Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.

The present embodiment provides a jacquard assembly spring assembling apparatus for mounting a spring 102 to a base plate 100 to achieve an elastic connection with a moving iron 101; the automatic assembly of the jacquard machine assembly (Stainbi module assembly) is realized by using the assembly equipment, so that the aims of improving the assembly efficiency and reducing the labor cost input are fulfilled.

Specifically, the assembly equipment mainly comprises a moving iron straightening mechanism and a spring feeding mechanism; the following is a detailed description of the constituent structure:

the moving iron straightening mechanism is mainly used for adjusting the position of the moving iron 101, so that the influence on subsequent spring installation and matching is avoided, and the situation that the spring cannot be placed due to the disordered position of the moving iron 101 shown in fig. 2 is avoided.

Specifically, referring to fig. 3 to 4, the moving iron centering mechanism includes a centering block 21 disposed on the bottom plate 100 and capable of moving along the length direction of the bottom plate 100, and a guide groove 211 is disposed on the bottom surface of the centering block 21; the guide grooves 211 correspond to the moving irons 101 one by one, and when the centering blocks 21 move on the bottom plate 100 towards the moving irons 101, the front ends of the moving irons 101 are gradually guided into the guide grooves 211 to realize the centering of the whole moving irons 101.

Optionally, the notch of the guide groove 211 is enlarged, that is, the notch of the guide groove 211 is designed to be a horn-shaped structure, so that the front end of the moving iron 101 can smoothly enter the guide groove 211.

In this embodiment, the bottom surface of the centering block 21 is further provided with a chute 212, and the slotting direction of the chute 212 is the same as the length direction of the bottom plate 100; the width of the sliding groove 212 is the same as that of the bottom plate 100, so that the sliding groove 212 can be clamped on the bottom plate 100; the centering blocks 21 slide on the base plate 100 through the slide grooves 212, in a manner that is shown in fig. 5-6.

By providing the slide groove 212, stability of movement of the centering block 21 with respect to the base plate 100 is ensured, and a great promoting effect is exerted on contact guiding of the guide groove 211 and the movable iron 101.

In this embodiment, referring to fig. 4 to 6, the bottom surface of the centering block 21 has a first surface and a second surface which are arranged in parallel, and the distance between the first surface and the top surface of the centering block 21 is smaller than the distance between the second surface and the top surface of the centering block 21, so that the first surface and the second surface form a stepped structure; the first surface is close to the movable iron 101, the guide groove 211 is formed in the first surface, the sliding groove 212 is formed in the second surface, and the depth of the sliding groove 212 is not smaller than the height difference between the first surface and the second surface.

The centering block 21 realizes the limited sliding with the bottom plate 100 by the sliding groove 212, and the centering block 21 can stably move along the length direction; in the process that the centering block 21 gradually approaches the moving iron 101, the first surface gradually contacts with the mounting block 103 in a fitting manner, then the guide groove 211 in the first surface contacts with the front end of the moving iron 101, and the moving iron 101 is adjusted and centered in the moving process; the stepped structure is favorable for stopping and limiting the movement of the straightening block 21; that is, when the centering block 21 moves until the stepped surface formed by the first surface and the second surface comes into contact with the mounting block 103, the centering block 21 cannot move any more, and at this time, the centering adjustment of the movable iron 101 is completed.

Optionally, the centering block 21 is further provided with a clearance groove 213, so that the centering block 21 is of a U-shaped structure, an opening of the clearance groove 213 faces the direction of the moving iron 101, and the clearance groove 213 is used for the clearance mounting block 103.

In the embodiment, referring to fig. 3, the moving iron centering mechanism includes a first driver 22 and a second driver 23, the centering block 21 is fixedly mounted on the first driver 22, and the first driver 22 is used for driving the centering block 21 to move along the length direction of the bottom plate 100; the first driver 22 is installed on the second driver 23, and the second driver 23 drives the first driver 22 up and down to make the centering block 21 approach or move away from the bottom plate 100.

Here, the second driver 23 is provided, which is mainly convenient for the assembled stanotbeer component to be taken out smoothly, that is, after the moving iron is straightened by the moving iron straightening mechanism, the spring feeding mechanism carries out the feeding assembly of the spring, after the assembly is completed, the first driver 22 retracts, and then the second driver retracts, so that the straightening block 21 is suspended, and the whole assembled stanotbeer component is taken out smoothly.

Optionally, the first actuator 22 and the second actuator 23 are air cylinders.

The spring feed mechanism is described in detail below:

referring to fig. 7, the spring feeding mechanism includes a tray 11, a material channel 12 and a feeding claw 13, a spring in the tray 11 enters the material channel 12, the feeding claw 13 catches the spring in the material channel 12, and the spring is placed on a bottom plate 100 to be connected with a moving iron 101.

In this embodiment, the tray 11 is a vibrating tray, and the vibrating tray provides a vibrating force to gradually enter the spring into the material channel 12.

In this embodiment, referring to fig. 8, the material channel 12 includes a vibrating feeding channel 121 and a rotating feeding channel 122.

The vibration feeding channel 121 is communicated with a discharge hole of the vibration disc in an aligned mode, so that the spring smoothly enters the vibration feeding channel 121 after passing through the vibration disc; the vibrating feeding channel 121 is mounted on a linear vibrator, and the vibration action of the linear vibrator enables a spring therein to be linearly transmitted along the vibrating feeding channel 121.

The rotary feeding channel 122 is used for being in butt joint with the vibrating feeding channel 121 and facilitating clamping of the subsequent feeding clamping claws 13, specifically, a feeding position and a feeding position are arranged on the rotary feeding channel 122, and the rotary feeding channel 122 is installed on a rotary cylinder; it should be noted that the feeding level and the feeding level need to be switched according to the rotation of the rotary feeding channel 122, that is, the feeding level will become the feeding level after the rotation of the rotary feeding channel 122, and the feeding level will become the feeding level; therefore, it can be understood that, no matter how the rotary feeding channel 122 rotates, the end of the rotary feeding channel 122 aligned and communicated with the discharge port of the vibrating feeding channel 121 is always defined as a feeding position; the position clamped by the feeding clamping claws 13 is always defined as a feeding position; so that the spring reaches the feed position through the vibrating feed channel 121; the rotary cylinder drives the rotary feeding passage 122 to rotate, so that the spring reaches the feeding position to facilitate the gripping of the feeding gripper 13.

The rotary feeding channel 122 is specially arranged for realizing a certain separation distance between adjacent springs so as to facilitate the clamping of the feeding clamping jaws 13; it can be understood that the springs in end-to-end contact are conveyed in a vibrating manner through the vibrating feeding channel 121, after the spring at the foremost end (first position) enters the feeding position, the vibrating feeding channel 121 stops vibrating, and meanwhile, the rotating feeding channel 122 starts rotating to rotate the spring entering the feeding position to the feeding position, so that the spring at the foremost end (first position) and the spring at the second position have a certain distance; when material loading clamping jaw 13 got the spring like this, can effectually avoid being located the interference influence of the spring of second position.

Alternatively, the rotary feeding channel 122 is a straight channel formed on a circular table, and the rotation angle of the rotary cylinder is fixed and rotated by 180 °.

Optionally, referring to fig. 7, a defective product detecting mechanism is disposed beside the feeding position of the rotary feeding channel 122, specifically, the detecting mechanism includes a manipulator, a detecting camera and a mechanical arm 141, the manipulator and the detecting camera are both fixedly mounted on the mechanical arm 141, the detecting camera is used for detecting whether a spring located on the feeding position is qualified, an unqualified spring is clamped by the manipulator and is removed, and a qualified spring is clamped by the feeding clamping claw 13 for next transportation.

In this embodiment, the feeding gripper 13 is used to grip qualified springs on the feeding position to transport the springs to the base plate 100; specifically, referring to fig. 9, the feeding jaw 13 is disposed to be movable up and down and left and right with respect to the base plate 100, and the feeding jaw 13 includes a first clamp body and a second clamp body, which are movably disposed with respect to each other to clamp the spring from the material supply position to the base plate 100.

Here, the left and right movement of the feeding clamping jaw 13 is realized by a left and right driver, and the up and down movement of the feeding clamping jaw 13 is realized by an up and down driver; specifically, the feeding clamping jaw 13 is fixed on an upper driver and a lower driver, and the upper driver and the lower driver are fixed on a left driver and a right driver; the driving movement of the left driver and the right driver enables the upper driver and the lower driver and the feeding clamping claws 13 to move synchronously, and the driving action of the upper driver and the lower driver enables the feeding clamping claws 13 to move up and down to clamp or place the spring.

The up-down driver and the left-right driver may be a motor, an electric cylinder, an air cylinder, or the like, which is commonly used at present, and the air cylinder is preferred in this embodiment.

In this embodiment, in order to improve the assembly efficiency, the spring feeding mechanisms are paired, and referring to fig. 7, it can be understood that the spring feeding mechanisms include a left spring feeding mechanism and a right spring feeding mechanism, and the left spring feeding mechanism is specially used for feeding a left spring in the stanobil module; the right spring feeding mechanism is specially used for feeding the right spring; the left spring feeding mechanism and the right spring feeding mechanism are identical in structure.

Considering that the spring placed by the feeding jaw 13 may have a certain deviation due to the elasticity of the spring and at the same time due to the limitation of the placing position of the spring on the bottom plate 100, resulting in unstable placing of the spring, in order to further ensure that the spring can be accurately and stably placed on the bottom plate 100, the assembling apparatus further includes a pressing mechanism, see fig. 9-10, for pressing the spring placed on the bottom plate 100 to ensure stable placing position, thereby ensuring stable connection of the spring and the moving iron 101.

Specifically, the pressing mechanism includes a pressing blade 151, the pressing blade 151 is disposed above the bottom plate and can move up and down, a pressing opening 152 is disposed on one side of the pressing blade 151 close to the bottom plate 100, and the pressing opening 152 is of a semicircular structure.

Here, in order to adapt to the shape structure of the spring, the pressing opening 152 with a semicircular structure is provided, and after the spring is placed on the feeding jaw 13, the pressing blade 151 descends again to make the pressing opening 152 act on the spring, so that the spring is further pressed, and the spring can be perfectly pressed into the placing position.

In this embodiment, the up-and-down movement of the pressing blade 151 is realized by the pressing cylinder 153, and the pressing cylinder 153 is fixed to the left and right drivers, which can be understood as that the driving action of the left and right drivers not only makes the up-and-down drivers and the feeding clamping jaw 13 move, but also makes the pressing blade 151 move synchronously.

The novel structure is designed, the automatic swing of the moving iron and the automatic feeding of the spring in the automatic assembly process are realized by arranging the moving iron swing mechanism and the spring feeding mechanism, and compared with the traditional manual operation, the process flow is simplified; the method has great promotion effect on the improvement of the assembly efficiency.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
