In the present embodiment, the index 4 includes a rotary base 41 and a jig disk 42. The rotating seat 41 is connected with the rotary driving member 2, and the jig tray 42 is sleeved on the rotating seat 41, specifically, the jig tray 42 is sleeved on the rotating seat 41 through a bearing. The jig disc 42 is provided with an adsorption station 420, specifically, the top surface of the adsorption station 420 is inclined relative to the axis of the jig disc 42, so that when the rotary driving piece 2 drives the jig disc 42 to rotate the adsorption station 420 to a position away from the connecting plate 12, the top surface of the adsorption station 420 can be kept horizontal, and when a product is driven to the position away from the connecting plate 12 by the adsorption station 420 and a vacuum environment is not formed in the adsorption station 420, the product cannot fall off the adsorption station 420; it adsorbs passageway 421 to run through on the adsorption station 420, specifically, the quantity of adsorbing station 420 is four, be first adsorption station 420 respectively, second adsorption station 420, third adsorption station 420 and fourth adsorption station 420, four adsorption station 420's structure is the same, four adsorption station 420 are along the circumferential edge reason of tool dish 42 with equal interval evenly distributed, and the contained angle degree that two adjacent adsorption station 420 formed is 90 degrees, it adsorbs passageway 421 to run through on each adsorption station 420. The jig tray 42 is driven by the rotary driving member 2 to make the suction channels 421 of the suction stations 420 correspond to the air holes 314, so that a vacuum channel and the suction channel 421 form a working channel.

When the marking index plate of the vacuum adsorption IC product is operated, the adsorption channel 421 is aligned with the air hole 314, a vacuum environment is formed in the vacuum channel, the product to be marked is placed on the adsorption station 420 through an upstream instrument, the product is adsorbed on the adsorption station 420 under the action of vacuum, and the rotary driving piece 2 drives the jig plate 42 and the product thereon to rotate, so that the product is rotated to the marking instrument; in the process that the adsorption channel 421 of the jig disc 42 rotates between the positions of the two air holes 314, the annular vent groove 315 prevents the adsorption station 420 from driving the product to rotate by too large an angle, so that the product falls.

In the in-service use process, because position and angle when a plurality of products are adsorbed in tool dish 42 are not unified, make the quality that adsorbs station 420 department is uneven for each of tool dish 42 after adsorbing a plurality of products, tool dish 42 takes place to swing or rock easily when rotatory, if guide holder 311 is fixed for guiding axle 32, tool dish 42 that takes place to swing or rock then can with guide holder 311 nonparallel, thereby restrict tool dish 42's rotation, cause tool dish 42 card to die, for avoiding the emergence of this kind of condition, in this embodiment, guiding axle 32 passes through linear bearing 320 swing joint with guide holder 311, under the combined action of guiding axle and elastic component, guide holder 311 can swing along with tool dish 42 together when making rotary driving piece 2 drive tool dish 42 rotatory, thereby guarantee tool dish 42's normal rotation.

When the guide holder 311 swings, the guide holder 311 inevitably tends to separate from the air vent block 313 to generate a gap, and if the guide holder 311 separates from the air vent block 313, the air duct 312 cannot be always communicated with the air hole 314, and the product may fall off the jig tray 42. In the present embodiment, the guide holder 311 applies pressure to the elastic portion 33 due to the pressure generated when the jig disc 42 rotates, the elastic portion 33 generates elastic force while compressing and deforming, and the elastic force is used as a pre-tightening force to support the guide holder 311, so that the guide holder 311 is always attached to the air vent block 313 in the process of swinging along with the jig disc 42, thereby ensuring that the air channel 312 and the air hole 314 are always communicated, and effectively preventing the product from falling off the jig disc 42 in the process of transportation.

The vacuum sensor and the comparator are well known in the art, and their operation is not described herein.

The using method of the marking device comprises the following steps:

in the initial state, the first suction nozzle 34 corresponds to the first adsorption station 420, the second suction nozzle 34 corresponds to the second adsorption station 420, the third suction nozzle 34 corresponds to the third adsorption station 420, the fourth suction nozzle 34 corresponds to the fourth adsorption station 420, and the marker 5 corresponds to the first adsorption station 420.

Setting the vacuum degree: the setting module 71 is operated to set the pre-rotation vacuum degree in the suction nozzles 34, for example, the pre-rotation vacuum degree in the suction channel 421 corresponding to the four suction stations 420 is set to be a value a in the setting module 71.

Starting: and opening the vacuum pressure regulating valve to form a vacuum environment in the adsorption channels 421, wherein the vacuum degrees in the adsorption channels 421 are all P values.

Adsorption: the upstream instrument forwards the product to a plurality of adsorb station 420 on, and specifically, the production line of three IC products is provided with in the upper reaches of marking the device, and every production line sets up a mechanical arm, and the mechanical arm will correspond the IC product of production line and transport to a plurality of adsorb station 420. When the product is adsorbed to the adsorption station 420, the vacuum degree in the adsorption channel 421 changes, and the monitoring module 72 obtains the actual vacuum degree, for example, when the third adsorption station 420 adsorbs the product, the vacuum degree of the adsorption channel 421 corresponding to the third adsorption station 420 changes from the P value to the actual vacuum degree a value, and at this time, the third branch monitoring module obtains the actual vacuum degree a value.

And (3) instruction generation: when the upper computer 73 receives the comparison result signal of the adsorbed product of the adsorption station 420, the upper computer 73 generates an instruction for controlling the rotary driving piece 2 to rotate the adsorption station 420 of the adsorbed product to the marking device 5; when the upper computer 73 receives a comparison result signal that the adsorption station 420 does not adsorb a product, the upper computer 73 generates an instruction for controlling the rotary driving part 2 not to drive the adsorption station 420 that does not adsorb a product to rotate to the marker 5. For example, when the comparison result signal indicates that a product is adsorbed on the third adsorption station 420, the upper computer 73 generates an instruction for controlling the rotary driving member 2 to rotate the third adsorption station 420 by 180 ° to the marker 5; when the comparison result signal indicates that the third adsorption station 420 does not adsorb any product, the upper computer 73 generates an instruction for controlling the rotary driving member 2 not to drive the third adsorption station 420 to rotate to the marking device 5. When two or more than two adsorb station 420 and adsorb the product simultaneously, host computer 73 generates control rotary driving piece 2 and rotates two or more than two adsorb station 420 according to anticlockwise in proper order to the instruction of marking device 5 department.

Rotating: after the control module 74 receives an instruction to rotate the adsorption station 420 of the adsorbed product to the marker 5, the control module 74 controls the rotary driving element 2 to rotate the adsorption station 420 of the adsorbed product to the marker 5, for example, after the control module 74 receives a control instruction from the upper computer 73, the control module controls the rotary driving element 2 to rotate the third adsorption station 420 of the adsorbed product to the marker 5, that is, the third adsorption station 420 is rotated to the air hole 314 corresponding to the marker 5, and in the process, the rotary driving element 2 only drives the jig disc 42 to rotate.

Marking: the marker 5 performs marking operation on the product to obtain a marked product. The marker 5 is provided with a sensor for sensing the marking progress, and the sensor feeds the marking progress back to the control module 74.

Material stripping: when the marking device 5 completes the marking operation, the control module 74 controls the vacuum pressure regulating valve connected to the first suction nozzle 34 to no longer provide a vacuum environment for the first suction nozzle 34, and the mechanical arm downstream of the production line clamps the marked product off the jig disk 42.

In the operation process of the marking device, the control module 74 controls the rotary driving element 2 to rotate the adsorption station 420 on which the product is adsorbed to the marking device 5 according to the data fed back by the sensor on the marking device 5 to perform marking operation, for example, when the product adsorbed by the third adsorption station 420 has completed marking operation, the sensor receives the signal of completing marking operation and sends the signal to the control module 74, and the control module 74 controls the rotary driving element 2 to directly drive the product adsorbed by the second adsorption station 420 or the fourth adsorption station 420 to the marking device 5 to perform marking operation. The arrangement of the sensors and the connection control method between the sensors and the control module 74 are well known in the art and will not be described herein.

In the existing control method of the jig disc 42 in the prior art, for example, the chinese utility model patent publication No. CN209747473U "a vacuum valve automatic rotating disc", the jig disc 42 is set according to the rotation program, when the setting program is used for marking operation on the production line of a plurality of IC products, because it only carries out the mechanized rotation of a fixed angle at each time, when a certain adsorption station 420 does not adsorb a product, the adsorption station 420 still rotates to the marker, so that the number of times of rotation of the jig disc 42 without purpose is increased.

Above-mentioned marking method of marking device, monitoring module 72 can monitor the actual vacuum in the operation passageway, and actual vacuum contrasts in monitoring module 72 with the degree of vacuum of prerotation, when the absorption station 420 that has adsorbed the product matches at the actual vacuum that corresponds the operation passageway with the degree of vacuum of prerotation, monitoring module 72 confirms that the absorption station 420 that has adsorbed the product promptly, rotary driving piece 2 drives tool dish 42 and directly rotates the absorption station 420 that has adsorbed the product to marker 5 department promptly, the absorption station 420 that has adsorbed the product need not stop in the fixed angle department of graduation, thereby reduce tool dish 42 and have no destination number of rotations, make tool dish 42 overall slew velocity accelerate, the seal character positioning accuracy improves, efficiency obtains great promotion. In addition, adsorbed product just stays on tool dish 42 always after being adsorbed by adsorption station 420, need not to change the transport apparatus, and two work tasks of transport and marking location just can be accomplished along with tool dish 42 rotation to adsorbed product, have further promoted the efficiency of marking the operation.

The vacuum sensor and the comparator are well known in the art, and their operation is not described herein.

The using method of the marking device comprises the following steps:

Starting: opening the vacuum pressure regulating valve 6 and forming a vacuum environment in the adsorption channel 421 corresponding to the first suction nozzle 34, wherein the vacuum degree of the first suction nozzle 34 is a P value; the rest suction nozzles 34 are introduced with negative pressure and keep introducing the negative pressure all the time to form a vacuum environment.

Adsorption: the upstream instrument transfers the product to the adsorption station 420 corresponding to the first nozzle 34. specifically, the production line is provided with a robot arm that transfers the IC product of the production line to the first adsorption station 420. When the product is adsorbed to the adsorption station 420, the vacuum degree in the air channel 312 corresponding to the suction nozzle 34 changes, and the monitoring module 72 obtains the actual vacuum degree, specifically, when the first adsorption station 420 adsorbs the product, the vacuum degree in the air channel 312 corresponding to the first suction nozzle 34 changes from the P value to the actual vacuum degree a value, and the monitoring module 72 obtains the actual vacuum degree a value.

Marking: the marker 5 performs marking operation on the product to obtain a marked product. The marker 5 is provided with a sensor for sensing the marking progress, and the sensor feeds the marking progress back to the control module 74. In the operation process of the marking device, when the sensor senses that the marking operation of the marker 5 is completed, the result is fed back to the control module 74, the control module 74 controls the rotary driving member 2 to drive the marked product to the verifier 8 through the jig disc 42, for example, when the product adsorbed by the first adsorption station 420 is completed, the sensor receives a signal of completing the marking operation and sends the signal to the control module 74, and the control module 74 controls the rotary driving member 2 to drive the marked product of the first adsorption station 420 to the verifier 8 for verifying operation.

And (4) checking: the marked product is driven by the corresponding adsorption station 420 to rotate to the checker 8 to check whether the marking is complete.

Material stripping: when the checker 8 checks that the marking is successful, the corresponding adsorption station 420 drives the checked marked product to the vacuum channel corresponding to the suction nozzle 34 connected with the vacuum pressure regulating valve 6, and specifically, the first adsorption station 420 drives the checked marked product to the air hole 314 corresponding to the first suction nozzle 34; the control module 74 controls the vacuum pressure regulating valve 6 to no longer provide a vacuum environment for the corresponding suction nozzle 34, and the mechanical arm on the downstream of the production line clamps the marked product from the index member 4, and specifically, the control module 74 controls the vacuum pressure regulating valve 6 to no longer provide a vacuum environment for the first suction nozzle 34, and the mechanical arm on the downstream of the production line clamps the marked product from the first adsorption station 420.

In the conventional control method for the jig disk 42, for example, the chinese utility model patent publication No. CN209747473U "a vacuum valve automatic turntable", the jig disk 42 only performs the mechanical rotation of a fixed angle at each time according to the setting of the rotation program, and when no product is adsorbed on the first adsorption station 420, the first adsorption station 420 is still driven by the rotary driving member 2 to rotate to the marker, so that the number of times of rotation of the jig disk 42 is increased.

Adsorbed product just stops on tool dish 42 from being adsorbed by adsorption station 420 back always, need not to change the transport apparatus, and two work tasks of transport and marking location just can be accomplished along with tool dish 42 rotation to adsorbed product, have further promoted the efficiency of marking the operation. In addition, the vacuum pressure regulating valve 6 determines whether to provide the vacuum environment for the first nozzle 34 according to the comparison result signal of the monitoring module 72, so as to avoid the sticky material caused by continuously providing the vacuum environment for the first nozzle 34.
