The present invention is further illustrated by the following examples, but is not limited thereby in the scope of the examples described below.

Referring to fig. 1, a semi-automatic lens assembly apparatus according to an embodiment of the present invention includes a lens barrel and a target lens, wherein the target lens is pre-placed on the lens barrel and then assembled by the semi-automatic lens assembly apparatus according to the present invention. Herein, the objective lens is understood as a lens to be assembled into the lens barrel to distinguish other lenses by name.

The semi-automatic lens assembling device comprises a positioning module 1, a pressing and glue distributing module 2, a material pushing module 3 and an assembly line module 4. The positioning module 1 is used for positioning the lens, the pressing and glue distributing module 2 is used for pressing a target lens of the lens positioned on the positioning module 1 and enabling the target lens to be bonded on the lens cone, and the assembly line module 4 is used for receiving the lens pushed out by the material pushing module 3 and conveying the lens to the next work station.

The lens barrel is positioned by the positioning module 1, the target lens on the lens barrel can be positioned, and the lens is kept stable in subsequent pressing and dispensing operations by the positioning module 1, so that the assembling accuracy of the lens barrel and the target lens is improved, and the assembling quality consistency of the target lens and the lens barrel and the yield of products are effectively improved. During specific operation, the positioning module 1 can select a positioning block, the positioning block directly or indirectly positions the lens, and the positioning block can position the lens barrel in a limited manner in certain directions.

The pressing and glue spreading module 2 has a function of pressing the target lens and a function of bonding the lens cone and the target lens. The lens is always positioned on the positioning module 1 in the operation of pressing the target lens and the operation of bonding the lens barrel and the target lens, namely the lens does not need to be moved between the pressing operation and the bonding operation, so that the time for carrying the lens between the two operations is saved, and the assembly efficiency is improved; and manual operation is reduced, so that the cleanliness of the lens is kept in a better state, and the subsequent cleaning times of the lens can be reduced.

The assembly line module 4 has a transmission function, and the lens is pushed onto the assembly line module 4 by the pushing module 3 and then transmitted to the next work station, so that the semi-finished lens does not need to be manually carried, the assembly efficiency of the whole lens is further improved, and meanwhile, the cleanliness of the lens is further kept in a better state due to the reduction of manual operation actions.

In other words, the waiting time of the person is utilized during the lens assembling process, so as to further improve the working efficiency.

Therefore, the embodiment of the invention saves the manual carrying time between the pressing operation and the bonding operation, the time for conveying the lens to the next work station after assembling one lens and the time for waiting by personnel in the lens assembling process through the mutual cooperation of the positioning module 1, the pressing and glue spreading module 2, the material pushing module 3, the pipeline module 4 and the modules, thereby improving the assembling efficiency of the lens by shortening the assembling time of the lens cone and the target lens.

In the example of the present invention, the pressing and glue dispensing module 2 includes a pressing unit 21, a glue dispensing unit 22, and a linear moving unit 23, the pressing unit 21 is used for pressing the target lens, the glue dispensing unit 22 is used for dispensing glue to the lens so as to bond the target lens to the lens barrel, the linear moving unit 23 outputs a horizontal and vertical linear reciprocating motion, and an output end of the linear moving unit is connected to the pressing unit 21 and the glue dispensing unit 22.

The pressing unit 21 and the glue dispensing unit 22 work independently, but the transverse movement and the vertical movement of the pressing unit 21 and the glue dispensing unit 22 are controlled by the linear movement unit 23, and the linear movement unit 23 can be provided with a plurality of output ends so as to meet the movement requirements of the pressing unit 21 and the glue dispensing unit 22. The linear motion output by the linear motion unit 23 can be realized based on pneumatic technology, for example, by controlling the linear motion of the corresponding component by a cylinder.

In the present example, the pressing and glue dispensing module 2 bonds the target lens and the lens barrel by dispensing, that is, the shadowless glue is sprayed by the glue dispensing unit 22 at several selected positions in the circumferential direction of the target lens to achieve bonding with the lens barrel, the number of the selected positions may be multiple, for example, four, and the selected positions are preferably evenly spaced.

In an example of the present invention, the semi-automatic lens assembling apparatus further includes a pre-baking module (illustrated in the figure), and the lens is configured to be baked by the pre-baking module after the dispensing is completed. The pre-baking module adopts ultraviolet light to bake the lens so that the shadowless glue between the target lens and the lens cone is cured to a certain degree. And after dispensing, pre-baking is carried out, which is favorable for ensuring the assembly precision of the lens cone and the target lens. The baking at the position can also be understood as irradiation, namely, the working principle of the pre-baking module is that ultraviolet light is adopted to irradiate the lens, so that the shadowless glue is cured.

Referring to fig. 2, in the example of the present invention, the semi-automatic lens assembling apparatus further includes a plane baking module 5, and the plane baking module 5 is configured to bake the lens pushed out by the pushing module 3. The lens is baked again after being pushed out by the material pushing module 3, so that the shadowless glue between the target lens and the lens cone is better cured.

The plane baking module 5 adopts an external light baking lens, baking at the position can also be understood as irradiation, namely, the working principle of the plane baking module 5 is that ultraviolet light is adopted to irradiate the lens so as to cure the shadowless glue.

The plane baking module 5 and the pre-baking module bake the lens, wherein the purpose of the pre-baking module is to cure the glue material to a certain degree, so as to improve the accuracy of the relative position of the target lens and the lens barrel before entering the plane baking module 5, and the purpose of the plane baking module 5 is to cure the glue material to a better state, so as to stably and fixedly connect the target lens and the lens barrel.

Preferably, the plane baking module 5 is disposed above the assembly line module 4, and the lens is baked from above in the process of going to the next work station along with the assembly line module 4.

One of the technical effects of adopting the mode of combining the pre-baking module and the plane baking module 5 to cure the glue material is as follows: the assembling precision between the target lens and the lens barrel is ensured to be high, and meanwhile, in the time period that one lens is baked by the plane baking module 5, the other lens can be placed at the positioning module 1 for assembling, so that the assembling efficiency of the lens is improved. Indeed, in other examples, as an alternative, the lens may be baked by only using the pre-baking module to make the adhesive material stably solidified and then pushed out, and the lens is not subjected to other baking operations from being pushed out to being conveyed to the next station, and accordingly, the flat baking module 5 is not necessarily present in this example.

The above-listed examples illustrate a semi-automatic lens assembling apparatus based on a dispensing technique, and in other examples, the glue dispensing unit 22 may also bond the target lens and the lens barrel by a hot-melting technique as an alternative technique. The difference between the example based on the hot-melt technology and the example based on the dispensing technology is that the semi-automatic lens assembling apparatus based on the hot-melt technology is not provided with the pre-baking module and the planar baking module 5.

In the present example, the pushing module 3 outputs a horizontal linear reciprocating motion, and the pushing module 3 is reset after pushing out the lens, so as to assemble the next lens. Indeed, in other examples, as an alternative means, the pushing module 3 may be made to output linear reciprocating motions in other directions to push the lens. Preferably, the linear reciprocating motion of the pushing module 3 is realized by a cylinder.

In an example of the present invention, the semi-automatic lens assembling apparatus further includes a turnover jig through which the lens is set to be carried. Realize the location to the camera lens through fixing a position the turnover tool on orientation module 1, make the camera lens push the assembly line in through promoting the turnover tool.

The turnover jig is used as a bearing body of the lens and can limit the rotation and the transverse movement of the lens cone. The lens is usually small and light, and the lens cone are assembled after being carried on the turnover jig, so that the stability of the lens in the assembling process is improved, the assembling precision is ensured, and the product yield is improved.

In the example of the invention, the line module 4 comprises a conveyor belt to feed the shots to the next station. The next station may be for assembling another lens on the lens barrel, or other assembling operations of the lens barrel.

When a plurality of lenses need to be assembled on one lens, it is preferable that one assembly line module 4 corresponds to a plurality of semi-automatic lens assembling devices arranged at intervals. After one lens is assembled, the lens is conveyed to a work station where the next semi-automatic lens assembling device is located by a conveyor belt, another lens is manually placed on the lens cone, and then the assembling work of the lens at the work station is started.

Referring to fig. 3, in the present embodiment, the semi-automatic lens assembling apparatus further includes an operation table module 6. The positioning module 1, the pressing and glue spreading module 2 and the pushing module 3 are all arranged on the operating platform.

The line module 4 is disposed at one side of the table to correspond to a plurality of stations, facilitating continuous transfer of the lenses between the stations. Preferably, a guide 62 is provided at one side of the positioning module 1, and the guide 62 has a slide groove. The both ends of guide 62 are adjoined with orientation module 1 and assembly line module 4 respectively, and the turnover tool is pushed out the back by the windrow module, gets into the spout steadily and transition to assembly line module 4 steadily.
