[0002] With the continuous upgrading of mobile phones, MP3, MP4 and other electronic products, the products tend to be thinner and lighter, and the requirements for the strength and light transmittance of glass products used as windows are getting higher and higher. In order to make thinner glass have greater impact resistance, extrusion resistance and high light transmittance, more and more glass lens polishing, grinding and strengthening processes have emerged.

[0003] During the production process of camera lenses, it is often necessary to apply a film to the camera lenses to provide temporary protection for the camera lenses, such as as a mask for ink silk screen printing, or as a mask for some local strengthening treatments, or as a mask for laser processing, or as a full cover to protect the camera from mechanical scratches.

[0004] Many film laminating operations require that the position correspondence between the lens and the film sheet has a high precision requirement. The corresponding position error between the film sheet and the lens reaches the micron level. If the lens or the film sheet is misaligned, it will cause misalignment in the subsequent process, affecting the quality of the finished lens. Existing film laminating operations mainly rely on manual operation with mechanical assistance. However, manual operation is difficult to meet the precision requirements of many film laminating operations. The laminating precision control is difficult, and there is a high defect rate in the subsequent inspection stage, resulting in material waste and increased processing costs.

[0036] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] See also Figure 1-2As shown, the present invention provides a lens film sticking jig 1, comprising a lens positioning film 11, a lens positioning frame 12 and a lens placing component 14, wherein the lens placing component 14 is provided with a lens placing jig 141 and a plurality of first positioning pins 1422, the outer diameter of the top end of the first positioning pin 1422 gradually decreases in the direction away from the first positioning pin 1422, the lens placing jig 141 is used to place a plurality of lenses 13, the plurality of first positioning pins 1422 are telescopically arranged on the periphery of the lens placing jig 141, the lens positioning frame 12 is detachably sleeved on the periphery of the lens placing jig 141, the lens positioning frame 12 is provided with first positioning holes 121 corresponding to the positions of the plurality of first positioning pins 1422, when the first positioning pin 1422 is converted from a retracted state to an extended state, the top end of the first positioning pin 1422 cooperates with the first positioning hole 121 to drive the position of the lens positioning frame 12 to be finely adjusted; the lens positioning film 11 is used to cover the lens positioning frame 12 and the top of the lens placing jig 141.

[0038] The lens positioning film 11 has an adhesive force on the side facing the lens positioning frame 12, which can bond and position the lens positioning frame 12 and the lens 13. Specifically, the adhesive force can be possessed by the film positioning film 21 itself, such as the film positioning film 21 adopts a smooth PET film, which has a certain adsorption effect on the smooth surface; or, the adhesive force can be obtained by forming an adhesive layer on the surface of the film positioning film 21. It should be noted that if an adhesive layer is used, the adhesive layer needs to be torn off along with the film positioning film 21 to avoid residual adhesive on the lens 13 and the lens positioning frame 12.

[0039] The lens film-sticking jig 1 is used to temporarily position a plurality of lenses 13. The plurality of lenses 13 are first fixed at certain positions in a lens positioning frame 12, and then the lenses 13 and the lens positioning frame 12 are respectively attached via a lens positioning film 11. The lens positioning frame 12 can then be used as a carrier for the plurality of lenses 13 to perform subsequent film-sticking operations and other processing steps.

[0040] Specifically, the working process of the lens film sticking fixture 1 is as follows:

[0041] Fix the lens placement jig 141 on the lens placement component 14, place multiple lenses 13 at the preset positions of the lens placement jig 141, pre-place the lens positioning frame 12 on the periphery of the lens placement jig 141, extend multiple first positioning pins 1422, the first positioning pins 1422 are concentrically matched with the first positioning holes 121, and fine-tune the lens positioning frame 12 to a predetermined position so that the positions of the lens positioning frame 12 and the lens placement jig 141 are relatively fixed, and then cover the lens positioning frame 12 and the lens placement jig 141 with a lens positioning film 11, the periphery of the lens positioning film 11 is bonded to the lens positioning frame 12, and the middle part of the lens positioning film 11 is used to bond and fix the multiple lenses 13 on the lens placement jig 141, so that the lens positioning frame 12, the lens positioning film 11 and the multiple lenses 13 form a whole, and the overall structure formed by the lens positioning frame 12, the lens positioning film 11 and the multiple lenses 13 is taken out and can be used for subsequent process operations.

[0042] The lens positioning frame 12 is provided with a plurality of first positioning holes 121, which can be used as positioning references in subsequent processes, so as to realize simultaneous positioning of a plurality of lenses 13, and also facilitate fixed-point processing in subsequent process flows. In order to ensure the relative position accuracy between the lens positioning frame 12 and the plurality of lenses 13, that is, it is necessary to ensure the position accuracy between the lens positioning frame 12 and the lens placement jig 141, a plurality of retractable first positioning pins 1422 are provided on the periphery of the lens placement jig 141, and the top of the first positioning pin 1422 is a conical structure with a gradually decreasing outer diameter. When placing the lens positioning frame 12 After that, the first positioning pin 1422 extends out. Even if there is a certain position deviation when the lens positioning frame 12 is placed, the first positioning hole 121 can be driven to a position cocentric with the first positioning pin 1422 through the cooperation of the top of the conical structure of the first positioning pin 1422 and the first positioning hole 121, thereby ensuring the position accuracy of the lens positioning frame 12. After the lens positioning film 11 is attached to fix the position of the lens 13 and the lens positioning frame 12, the relative accuracy of their positions is high, which can ensure that multiple lenses 13 are in the predetermined position in multiple subsequent operations, thereby ensuring the accuracy of the lens 13 processing.

[0043] In one embodiment, the lens positioning frame 12 is a square metal frame.

[0044] like Figure 1As shown, in one embodiment, the lens placement assembly 14 includes a lens sliding seat 142 and the lens placement jig 141, and the lens placement jig 141 is provided with a plurality of lens grooves 1411 for placing the lenses 13, and the shape of the lens grooves 1411 is adapted to the shape of the lenses 13, and the lens placement jig 141 is detachably arranged on the lens sliding seat 142, and a plurality of the first positioning pins 1422 are telescopically arranged on the lens sliding seat 142.

[0045] By detachably installing the lens placement jig 141, it is convenient to replace the lens placement jig 141. In actual operation, the shapes of camera lenses of different mobile phones are different. Multiple lens placement jigs 141 corresponding to multiple lenses can be set for replacement, thereby achieving the film-applying operation of lenses of different specifications by the same lens film-applying jig 1, saving jig costs and improving the adaptability and adjustability of the lens film-applying jig 1.

[0046] It should be noted that the number of the first positioning holes 121 is preferably 3 or more. When the number of the first positioning holes 121 is too low, it is easy to cause a slight angular deviation of the lens positioning frame 12 during fine-tuning, which is not conducive to improving the positioning accuracy.

[0047] In one embodiment, the number of the first positioning holes 121 is four, the lens placement fixture 141 is a square structure, and the four first positioning holes 121 are respectively located at the four corner positions of the lens placement fixture 141 .

[0049] Along the sliding direction of the lens sliding seat 142, the first guide groove 1431 is provided with a first concave section 1433, a first transition section 1434 and a first convex section 1435 in sequence, the depth of the first concave section 1433 is greater than the depth of the first convex section 1435, and the first transition section 1434 is a slope structure provided between the first concave section 1433 and the first convex section 1435, for ensuring the smooth movement of the first positioning pin 1422;

[0050] When the lens sliding seat 142 is located at the first position, the bottom end of the first positioning pin 1422 abuts against the first recessed section 1433, the first positioning pin 1422 is in a contracted state on the lens sliding seat 142, and the first spring 1423 is naturally extended;

[0051] When the lens sliding seat 142 is in the second position, the bottom end of the first positioning pin 1422 abuts against the first protruding section 1435 , the first positioning pin 1422 is in an extended state on the lens sliding seat 142 , and the first spring 1423 is compressed.

[0052] The lens sliding seat 142 and the lens sliding base 143 are slid relative to each other to drive the displacement of the first recessed section 1433, the first transition section 1434 and the first raised section 1435 of the first positioning pin 1422 in the first guide groove 1431, thereby simultaneously driving the lifting of multiple first positioning pins 1422. The structure of the first guide groove 1431 can ensure the movement synchronization of each first positioning pin 1422, and ensure the synchronization of position fine-tuning of each first positioning hole 121 on the lens positioning frame 12. At the same time, the sliding operation of the lens sliding seat 142 can be performed by manual or mechanical push, and the operation is relatively convenient, which can effectively avoid the influence of errors existing in manual operation.

[0053] like Figure 1 As shown, in one embodiment, a first limiting wall 1432 is disposed around the top periphery of the lens sliding base 143 , and the first limiting wall 1432 is used to limit the sliding direction and displacement range of the lens sliding seat 142 .

[0054] In one embodiment, a first embedding opening 1421 is defined on the lens sliding seat 142 , and the lens placing fixture 141 is detachably embedded in the first embedding opening 1421 .

[0055] See also Figure 3 to Figure 5As shown, another embodiment of the present invention provides a film film fixture 2, including a film positioning film 21, a film positioning frame 22 and a film placement component 24, the film placement component 24 is provided with a film placement fixture 241 and a plurality of second positioning pins 2422, the top outer diameter of the second positioning pin 2422 gradually decreases in the direction away from the second positioning pin 2422, the film placement fixture 241 is used to place a plurality of films 23, and the plurality of second positioning pins 2422 can be retractably arranged on the outer surface of the film placement fixture 241 The diaphragm positioning frame 22 is detachably mounted on the outer periphery of the diaphragm placing jig 241, and the diaphragm positioning frame 22 is provided with second positioning holes 221 corresponding to the positions of a plurality of second positioning pins 2422. When the second positioning pins 2422 are transformed from a retracted state to an extended state, the top ends of the second positioning pins 2422 cooperate with the second positioning holes 221 to drive the fine adjustment of the position of the diaphragm positioning frame 22; the diaphragm positioning film 21 is used to cover the top of the diaphragm positioning frame 22 and the diaphragm placing jig 241.

[0056] The side of the diaphragm positioning film 21 facing the diaphragm positioning frame 22 has an adhesive force, which can bond and position the diaphragm positioning frame 22 and the diaphragm 23. Specifically, the adhesive force can be possessed by the diaphragm positioning film 21 itself, such as the diaphragm positioning film 21 adopts a smooth PET film, which has a certain adsorption effect on the smooth surface; or, the adhesive force can be obtained by forming an adhesive layer on the surface of the diaphragm positioning film 21. It should be noted that if an adhesive layer is used, the adhesive layer needs to be torn off along with the diaphragm positioning film 21 to avoid residual adhesive on the diaphragm 23 and the diaphragm positioning frame 22.

[0057] The diaphragm pasting jig 2 is used to temporarily position multiple diaphragms 23. The multiple diaphragms 23 are first fixed at a certain position in the diaphragm positioning frame 22, and then the diaphragms 23 and the diaphragm positioning frame 22 are respectively pasted through the diaphragm positioning film 21. Then, the diaphragm positioning frame 22 can be used as a carrier of the multiple diaphragms 23 to perform subsequent film pasting operations and other processing steps.

[0058] Specifically, the workflow of the diaphragm film sticking fixture 2 is as follows:

[0059] The diaphragm placement jig 241 is fixed on the diaphragm placement assembly 24, a plurality of diaphragms 23 are placed at the preset positions of the diaphragm placement jig 241, a diaphragm positioning frame 22 is pre-placed on the periphery of the diaphragm placement jig 241, a plurality of second positioning pins 2422 are extended, the second positioning pins 2422 are concentrically matched with the second positioning holes 221, the diaphragm positioning frame 22 is finely adjusted to a predetermined position, so that the positions of the diaphragm positioning frame 22 and the diaphragm placement jig 241 are relatively fixed, and then the diaphragm positioning frame 22 is fixed to the predetermined position. The frame 22 and the diaphragm placement jig 241 are covered with a diaphragm positioning film 21, the periphery of the diaphragm positioning film 21 is bonded to the diaphragm positioning frame 22, and the middle part of the diaphragm positioning film 21 is used to bond and fix multiple diaphragms 23 on the diaphragm placement jig 241, so that the diaphragm positioning frame 22, the diaphragm positioning film 21 and the multiple diaphragms 23 form a whole, and the overall structure formed by the diaphragm positioning frame 22, the diaphragm positioning film 21 and the multiple diaphragms 23 is taken out and can be used for subsequent process operations.

[0060] The diaphragm positioning frame 22 is provided with a plurality of second positioning holes 221, which can be used as positioning references in subsequent processes, thereby realizing simultaneous positioning of a plurality of diaphragms 23, and facilitating fixed-point processing in subsequent process flows.

[0063] By installing the diaphragm placement jig 241 detachably, it is convenient to replace the diaphragm placement jig 241. In actual operation, there are certain differences in the shapes of camera diaphragms of different mobile phones. Multiple diaphragm placement jigs 241 corresponding to multiple diaphragms can be set for replacement, thereby realizing the film-sticking operation of diaphragms of different specifications by the same diaphragm sticking jig 2, saving jig costs and improving the adaptability and adjustability of the diaphragm sticking jig 2.

[0064] It should be noted that the number of the second positioning holes 221 is preferably 3 or more. When the number of the second positioning holes 221 is too small, it is easy to cause a slight angular deviation of the diaphragm positioning frame 22 during fine-tuning, which is not conducive to improving the position accuracy.

[0065] In one embodiment, the number of the second positioning holes 221 is four, the diaphragm placement fixture 241 is a square structure, and the four second positioning holes 221 are respectively located at the four corner positions of the diaphragm placement fixture 241 .

[0066] like Figure 2 As shown, in one embodiment, the diaphragm placing assembly 24 also includes a diaphragm sliding base 243, and the diaphragm sliding base 242 can be slidably arranged on the diaphragm sliding base 243 between the third position and the fourth position, and a plurality of second connecting holes are provided on the diaphragm sliding base 242, and a plurality of second positioning pins 2422 are slidably arranged in the plurality of second connecting holes in a one-to-one correspondence, and the inner diameter of the second positioning hole 221 is consistent with the maximum outer diameter of the top end of the second positioning pin 2422, and a plurality of second guide grooves 2431 are provided on the diaphragm sliding base 243 at positions corresponding to the plurality of second connecting holes, and the bottom end of the second positioning pin 2422 passes through the second connecting hole and abuts against the second guide groove 2431, and a second spring 2423 is provided between the second positioning pin 2422 and the diaphragm sliding base 242, and the second spring 2423 is used to provide power for the telescopic return stroke of the second positioning pin 2422;

[0067] Along the sliding direction of the diaphragm sliding seat 242, the second guide groove 2431 is provided with a second recessed section 2433, a second transition section 2434 and a second raised section 2435 in sequence, the depth of the second recessed section 2433 is greater than the depth of the second raised section 2435, and the second transition section 2434 is a slope structure provided between the second recessed section 2433 and the second raised section 2435, for ensuring the smooth movement of the second positioning pin 2422;

[0068] When the diaphragm sliding seat 242 is located at the third position, the bottom end of the second positioning pin 2422 abuts against the second recessed section 2433, the second positioning pin 2422 is in a contracted state on the diaphragm sliding seat 242, and the second spring 2423 naturally extends;

[0069] When the diaphragm sliding seat 242 is in the fourth position, the bottom end of the second positioning pin 2422 abuts against the second protruding section 2435, the second positioning pin 2422 is in an extended state on the diaphragm sliding seat 242, and the second spring 2423 is compressed.

[0070] The diaphragm sliding seat 242 and the diaphragm sliding base 243 are slid relative to each other to drive the displacement of the second recessed section 2433, the second transition section 2434 and the second raised section 2435 of the second positioning pin 2422 in the second guide groove 2431, thereby simultaneously driving the lifting of multiple second positioning pins 2422. The structure of the second guide groove 2431 can ensure the movement synchronization of each second positioning pin 2422, and ensure the synchronization of position fine-tuning of each second positioning hole 221 on the diaphragm positioning frame 22. At the same time, the sliding operation of the diaphragm sliding seat 242 can be performed by manual or mechanical push, and the operation is relatively convenient, which can effectively avoid the influence of errors existing in manual operation.

[0071] like Figure 5 As shown, in one embodiment, a second limiting wall 2432 is disposed around the top periphery of the diaphragm sliding base 243 , and the second limiting wall 2432 is used to limit the sliding direction and displacement range of the diaphragm sliding seat 242 .

[0072] like Figure 1 As shown, in one embodiment, a second embedding opening 2421 is opened on the diaphragm sliding seat 242 , and the diaphragm placing fixture 241 is detachably embedded in the second embedding opening 2421 .

[0073] like Figure 1 to Figure 7As shown, another embodiment of the present invention provides a lens film bonding system, including a bonding jig, the lens film bonding jig 1 as described above, and the film film bonding jig 2 as described above, wherein the bonding jig is used to bond the multiple lenses 13 positioned by the lens positioning film 11 and the multiple film sheets 23 positioned by the film positioning film 21 in a one-to-one correspondence.

[0074] like Figure 6 As shown, in one embodiment, the bonding jig includes a pressing plate 3, a base plate 4 and a driving mechanism (not shown in the figure), the lens positioning frame 12 is detachably arranged on the base plate 4, the diaphragm positioning frame 22 is detachably arranged on the pressing plate 3, a plurality of first bonding positioning pins 41 are arranged on the base plate 4, and the plurality of first bonding positioning pins 41 correspond one-to-one to the positions of the plurality of first positioning holes 121 on the lens positioning frame 12, a plurality of second bonding positioning pins (not shown in the figure) are arranged on the pressing plate 3, and the plurality of second bonding positioning pins correspond one-to-one to the positions of the plurality of second positioning holes 221 on the diaphragm positioning frame 22, and the driving mechanism is used to drive the pressing plate 3 and the base plate 4 to close and separate from each other.

[0075] Since the lens-film bonding system adopts the above-mentioned lens-film bonding jig 1 and film-film bonding jig 2, it is possible to obtain a plurality of lenses 13 arranged with a certain position and a plurality of films 23 arranged with a certain position. At the same time, the plurality of lenses 13 are positioned by the lens positioning frame 12, and the plurality of films 23 are positioned by the film positioning frame 22, thereby reducing the difficulty of aligning the lenses 13 and the films 23 in the subsequent pressing of the pressing plate 3 and the base plate 4.

[0076] like Figure 7 As shown, in one embodiment, the outer shape of the lens positioning frame 12 is matched with the inner frame shape of the diaphragm positioning frame 22, and the lens positioning frame 12 can be embedded in the diaphragm positioning frame 22 to improve the pairing accuracy.

[0077] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
