In this embodiment, the aforementioned back adhesive 70 is a common material in the art, and is generally attached to the base film 90 (please refer to fig. 8 herein), when the back adhesive 70 needs to be attached, the back adhesive 70 is torn off from the base film 90 and then attached to the back of the camera module 60, and the edge portion 71 of the back adhesive 70 extending beyond the back of the camera module 60 is bent to be attached to the circumferential side wall of the camera module 60.

In this embodiment, the camera module adhesive-bonding device includes a base 10, a camera module jig 20, a back adhesive jig 30, and a pressing bending mechanism 40.

The base 10 may be a plate-shaped member. In other embodiments, the base 10 may be a separate bracket, or a surface portion of another device or other member with a supporting function.

The camera module fixture 20 can be reciprocally and reversely arranged on the base 10 at the first position and the second position for clamping at least one camera module 60. Wherein the first position and the second position correspond to positions of two opposite parts of the top surface of the base 10; the overturning direction of the camera module jig 20 is the F1 direction.

The back glue fixture 30 is fixedly connected to the top surface of the base 10 and located at a first position for providing the back glue 70 to the camera module 60.

The pressing bending mechanism 40 is disposed on the top surface of the base 10 and above the second position, and is used for bending the back adhesive 70 of the camera module 60.

In this embodiment, the camera module jig 20 is used to carry the camera module 60, and the adhesive back jig 30 is used to carry the adhesive back 70. When the camera module jig 20 is turned to the first position, the back glue jig 30 provides back glue 70 for the camera module 60 carried by the camera module jig 20, so that the back glue 70 is attached to the back surface of the camera module 60; then, the camera module jig 20 is turned over to the second position, and the back glue 70 is extended to the edge portion 71 outside the back of the camera module 60 by the pressing bending mechanism 40 to bend, so that the edge portion 71 is attached to the circumferential side wall of the camera module 60.

The working principle of the embodiment comprises: when the camera module jig 20 works, the camera module 60 is limited on the camera module jig 20 at the second position, and the back surface of the camera module 60 faces upwards; manually overturning the camera module jig 20 forward by 180 degrees to a first position, enabling the back of the camera module 60 to face downwards, enabling the back of the camera module 60 to abut against the back glue 70 on the back glue jig 30, and enabling the back glue 70 to be adhered to the back of the camera module 60; manually reversing the camera module jig 20 by 180 degrees to a second position, wherein the back of the camera module 60 faces upwards; the downward bending mechanism 40 is pressed downward, and the edge portion 71 extending to the outside of the back of the camera module 60 is bent downward and adhered to the side wall of the camera module 60 in the circumferential direction, wherein the state before the back 70 is bent is shown in fig. 9; the state of the back adhesive 70 after bending is shown in fig. 10.

In other embodiments, a servo motor or a cylinder or other automatic driving member may be used to drive the camera module fixture 20 to reciprocate, and the pressing bending mechanism 40 may also be an automatic pressing driving member, such as a linear module or a telescopic cylinder or other linear driving mechanism. The scheme can save labor cost and improve working efficiency, but improves structural complexity, and manufacturing cost and maintenance cost are higher. In this embodiment, the manually driven camera module fixture 20 is used to turn over and the pressing bending mechanism 40 is driven to bend the back adhesive 70, so that the structure can be simplified, the manufacturing cost and the maintenance cost can be reduced, but the efficiency is lower.

In other embodiments, the camera module fixture 20 is fixedly connected to the top surface of the base 10 and is located at the second position. The adhesive-back jig 30 can be reciprocally and reversely arranged on the top surface of the base 10 at the first position and the second position. When the camera module jig 20 works, the camera module 60 is limited on the camera module jig 20 at the second position, and the back surface of the camera module 60 faces upwards; manually turning the back adhesive jig 30 180 degrees to a second position to enable the back surface of the back adhesive 70 to face downwards, wherein the back surface of the back adhesive 70 is abutted against the back surface of the camera module 60, so that the back adhesive 70 is adhered to the back surface of the camera module 60; manually turning the adhesive-backed jig 30 to the first position; the down-press bending mechanism 40 is pressed down, and the edge portion 71 extending beyond the back of the image capturing module 60 is bent downward and adhered to the side wall in the circumferential direction of the image capturing module 60. The technical effect to be achieved by the application can also be achieved by adopting the scheme of the embodiment.

Compared with the prior art, the technical scheme of the embodiment has the following advantages:

2. The back adhesive attaching device for the camera module of the embodiment can replace manual work to complete the attaching process and the bending process of the back adhesive 70 of the camera module 60, and is beneficial to improving the attaching efficiency and the attaching precision of the back adhesive 70.

3. The back glue pasting device for the camera module can complete the back glue pasting 70 procedure and the back glue bending 70 procedure, so that the camera module 60 is prevented from being carried in a long distance between the two procedures, the carrying time is saved, and the back glue pasting 70 efficiency is improved.

Next, the structure of the technical solution of the present embodiment will be further described.

Referring to fig. 1, 2 and 3, in the present embodiment, the camera module fixture 20 includes a bottom plate 21. The bottom plate 21 is reciprocally rotatably disposed on a mounting seat protruding from the top surface of the base 10 through a rotation shaft. A plurality of sinking tables for placing the camera module 60 are arranged on the top surface of the bottom plate 21. All sinking tables are arranged in an array, each sinking table can be provided with one camera module 60, so that a plurality of camera modules 60 can be loaded at one time, the back glue 70 and the bending back glue 70 can be attached to a plurality of camera modules at one time later, and the working efficiency is improved. In other embodiments, the number and arrangement of the sinking tables may be flexibly set according to actual requirements, for example, all the sinking tables may be arranged in other manners; for another example, the number of setting stages may be one.

Further, the sinking platform comprises a groove 211 and a step part 212 arranged at the edge of the groove 211. The shape of the groove 211 is matched with the shape of the bottom of the camera module 60, the bottom of the camera module 60 is embedded into the groove 211, the position of the camera module 60 is limited by the groove 211, and the camera module 60 is prevented from being shifted along the surface of the bottom plate 21; the circumferential side wall of the bottom of the camera module 60 is abutted against the inner wall of the groove 211, and the position of the camera module 60 is limited by the friction between the circumferential side wall of the bottom plate 21 of the camera module 60 and the inner wall of the groove 211, so that the camera module 60 is prevented from being separated from the groove 211. The number of the step portions 212 is four, and the four step portions 212 may be disposed at equal intervals around the groove 211; when the camera module 60 needs to be disassembled, the operator can grasp the camera module 60 from the step part 212 by fingers, and as shown in the figure, the step part 212 can increase the exposed area of the camera module 60, so that the operator can conveniently take out the camera module 60. In other embodiments, there may be two stepped portions 212, for which two stepped portions 212 are disposed on opposite sides of the recess 211; in other embodiments, the step portion 212 may be one, and the step portion 212 is disposed around the groove 211 in an arc shape, a half-moon shape, a square shape, or other shapes.

Further, a buffer floating head structure is disposed in the groove 211. The buffer floating head structure includes a floating head 23 and a first elastic member 24. The floating head 23 is provided in the groove 211 so as to be movable up and down. Specifically, the cross section of the groove 211 along the axial direction is in an inverted T shape, and the shape of the floating head 23 is matched with the shape of the groove 211, so that the lower part of the floating head 23 can be clamped in the groove 211, and the floating head 23 is prevented from being separated from the groove 211 upwards. When the camera module 60 is embedded in the groove 211, the floating head 23 can abut against the bottom surface of the camera module 60, so as to play a role in supporting the camera module 60 to a certain extent, and avoid the camera module 60 from excessively sinking into the groove 211 under the action of self gravity, thereby affecting the precision and attaching quality of the follow-up adhesive tape 70 and the bending adhesive tape 70.

The first elastic member 24 is located between the bottom surface of the floating head 23 and the bottom wall of the recess 211, and is used for forming a deformation elastic force for forcing the floating head 23 to restore to the original position when the floating head 23 is retracted. When the camera module is attached to the back glue 70, the camera module 60 extrudes the floating head 23, the floating head 23 can adaptively move, the camera module 60 can also adaptively move, the floating head 23 is prevented from being in rigid contact with the top surface of the back glue jig 30, and the probability of damage of the camera module 60 due to rigid extrusion is reduced. The first elastic member 24 may be a linear spring, where the top end and the bottom end of the linear spring respectively abut against the bottom surface of the floating head 23 and the bottom wall of the groove 211. In other embodiments, the first elastic member 24 may be a silica gel pad or a rubber pad or other elastic member.

The top surface of the bottom plate 21 is convexly provided with a limit post 213. When the pressing bending mechanism 40 is pressed down, the limiting column 213 can abut against the bottom surface of the pressing bending mechanism 40, so as to avoid the pressing bending mechanism 40 from excessively pressing the camera module 60 to damage the camera module 60. Preferably, the number of the limiting columns 213 is plural, the notch of the groove 211 is square, four limiting columns 213 are arranged around each groove 211, and the four limiting columns 213 are arranged in a rectangular shape and correspond to four corners of the notch of the groove 211 one by one. The inner side of the limiting column 213 is provided with an L-shaped chute 214, and the chute 214 extends along the length direction of the limiting column 213 and is communicated with the inner cavity of the groove 211. When the camera module 60 is loaded, the camera module 60 moves into the groove 211 along the chute 214 at the inner side of the limit post 213, so that the camera module 60 is more accurately embedded into the groove 211. In other embodiments, the number of the limiting posts 213 is one or more, and the limiting posts 213 may be disposed at other positions on the top surface of the base 31, so long as they can limit the pressing bending mechanism 40 from excessively pressing.

In the present embodiment, the top surface of the base 10 is provided with a supporting seat 22, and the supporting seat 22 is disposed at the second position. When the camera module jig 20 is at the second position, the bottom plate 21 is abutted against the top surface of the abutment seat 22. The abutment seat 22 can limit the bottom plate 21 at a preset position, so that the bottom plate 21 is kept in a horizontal state when being positioned at the second position, and then the back glue 70 adhered to the back of the camera module 60 is positioned in a horizontal state, so that the subsequent pressing bending mechanism 40 can bend the back glue 70 to extend to all positions outside the back of the camera module 60.

Referring to fig. 1, 4, 5 and 6, in the present embodiment, the pressing and bending mechanism 40 is suspended above the base 10 by a set of support plates 50. The number of the support plates 50 may be two, and the two support plates 50 are symmetrically disposed on the top surface of the base 10.

The pressing bending mechanism 40 includes a turnover plate 41, a lifting driving structure 42, and a bending pressing plate. The turnover plate 41 is provided to the support plate 50 so as to be vertically turnover, and the maximum angle of the turnover is 90 degrees. The elevation driving structure 42 is provided to the inversion plate 41. The bending press plate is arranged on the lifting driving structure 42, and the lifting driving structure 42 drives the bending press plate to move up and down so that the bending press plate bends downwards to form the back glue 70 on the camera module 60. When the turnover plate 41 is turned upwards, the lifting driving mechanism and the bending press plate are upwards far away from the base 10, so that the distance between the bending press plate and the camera module fixture 20 can be increased, and more operation space is provided for the process of loading or taking down the camera module 60.

The bending platen includes a base plate 43 and a ram structure. The substrate 43 is provided on the elevation driving structure 42. The pressing head structure is disposed on the bottom surface of the substrate 43, and is used for bending the back glue 70 of the camera module 60.

The lifting driving structure 42 may be a quick clip, which may be a product commonly used in the market, and the structural principle of the quick clip will not be described in detail herein. For the common quick clamp in the market, the movable end of the quick clamp can be moved up and down by manually pulling the handle of the quick clamp. The top surface of the base plate 43 is fixedly connected with the movable end of the quick clamp, so that the quick clamp can drive the base plate 43 to move up and down, and the base plate 43 drives the pressure head structure to move up and down; when the ram structure moves down, the ram structure bends the back glue 70. In other embodiments, the lift drive mechanism 42 may employ a linear module or a telescopic cylinder or other linear drive member to automate the up and down movement of the substrate 43.

Further, the number of the arranged press head structures is the same as the number of the arranged sinking tables, and in the process of bending the back glue 70, the positions of the press head structures correspond to the positions of the sinking tables one by one, so that the back glue 70 on the back of the camera module 60 on the sinking tables is bent by the press head structures at the same time.

The bottom surface of the substrate 43 is provided with a plurality of guide grooves 431, the number of the guide grooves 431 is the same as that of the pressing head structures, and each guide groove 431 is arranged corresponding to each pressing head structure one by one. The ram structure includes a floating ram 44, a second resilient member 45, and three bending ribs 432. The floating ram 44 is movably disposed in the guide groove 431 and partially exposed outside the guide groove 431. The guide groove 431 has a T-shaped cross section in the axial direction thereof, and the floating ram 44 has a shape matching the shape of the guide groove 431. The upper part of the floating pressure head 44 is clamped in the guide groove 431, so that the floating pressure head 44 is prevented from being separated from the guide groove 431 downwards. The lower portion of the floating ram 44 is exposed outside the guide groove 431 to bend the back adhesive 70.

The three bending convex strips 432 are respectively and convexly arranged at three edges of the notch of the guide groove 431, and each bending convex strip is arranged along the length direction of one notch edge of the guide groove 431. When the substrate 43 is pressed down, the three bending ribs 432 respectively press the back adhesive 70 to extend to three edge portions 71 outside the back of the camera module 60. Meanwhile, the bottom surface of the floating pressure head 44 can also squeeze the back adhesive 70, so that the back adhesive 70 is more firmly adhered to the back surface of the camera module 60. Of course, in other embodiments, the number of the bending ribs 432 may be increased or decreased according to actual needs, or may be arranged in other manners, so long as the bending adhesive 70 is provided.

The second elastic member 45 is disposed between the top surface of the floating ram 44 and the top wall of the guide groove 431 to form a deformation elastic force for forcing the floating ram 44 to return to its original position after the floating ram 44 moves upward. In operation, the second elastic member 45 can provide a cushioning effect to the floating ram 44. When the back glue 70 is bent, the camera module 60 is abutted against the floating pressure head 44, the floating pressure head 44 can adaptively and upwards displace, rigid contact between the floating pressure head 44 and the top surface of the camera module 60 is avoided, and the probability of damage of the camera module 60 due to rigid extrusion is reduced. The second elastic member 45 may be a linear spring, and the top end and the bottom end of the linear spring respectively abut against the top surface of the floating ram 44 and the bottom wall of the guide groove 431. In other embodiments, the second elastic member 45 may be a silica gel pad or a rubber pad or other elastic member.

The vacuum generator 81 may be a product commonly used in the market, and the structural principle of the vacuum generator 81 is not described in detail herein because the structural principle of the vacuum generator 81 is the prior art. The manual air valve 82 is arranged on the pipeline and is used for controlling the on-off of the pipeline so as to control the suction nozzle to form a negative pressure state or stop a negative pressure state.

In the present embodiment, the adhesive-back jig 30 further includes a release assembly for assisting the separation of the adhesive-back 70 from the base film 90. The stripping assembly comprises two guide convex strips 311, a cover plate 314 and two magnetic attraction groups. The two guide convex strips 311 are juxtaposed and protruded on the top surface of the base 31 at intervals. The two magnetic attraction sets are arranged on the top surface of the base 31 in parallel and at intervals, and the two magnetic attraction sets are positioned between the two guide convex strips 311. The magnetic attraction groups extend along the length direction of the guide convex strips 311, and the bearing grooves 312 are positioned between the two magnetic attraction groups; the cover 314 is disposed between the two guide ribs 311 in a manner capable of moving back and forth along the length direction of the guide ribs 311, and the cover 314 is magnetically attracted to the two magnetic attraction sets.

In operation, referring to fig. 7, the rolled base film 90 is manually laid between the two guide ribs 311. The two guiding convex strips 311 limit the base film 90, so that the base film 90 is laid on the top surface of the base 31 according to a preset position, and the surface attached with the back glue 70 faces downwards. Each of the backings 70 attached to the base film 90 corresponds one by one to each of the carrying grooves 312. The cover 314 is manually installed between the two guide convex strips 311, the cover 314 is magnetically attracted to the two magnetic attraction groups, so that the cover 314 is pressed to the bearing groove 312 by the magnetic attraction force of the magnetic attraction groups, and the cover 314 presses the base film 90 to the bearing groove 312, so that the suction nozzle of the subsequent bearing groove 312 can absorb the back glue 70. The manual air valve 82 is manually opened and the suction nozzle creates a negative pressure and adsorbs the adhesive backing 70. An operator grasps one end of the base film 90 and tears it backward (i.e., in the direction F2 in the drawing), while the operator drags the cover 314 backward (i.e., in the direction F2 in the drawing) with the other hand; in this process, the magnetic attraction group maintains the state of attracting the cover plate 314, so that the cover plate 314 is moved while maintaining the state of pressing the base film 90; further, since the suction nozzle adsorbs the back adhesive 70, the back adhesive 70 can be detached from the base film 90 when the base film 90 is torn; when the base film 90 is completely torn, all the back glue 70 on the base film 90 can be separated from the base film 90 and is adsorbed on the carrying groove 312 one by one correspondingly, so as to be attached to the back of each camera module 60.

In the above working process, the two magnetic attraction groups can simultaneously adsorb two opposite sides of the cover plate 314 in the width direction, so that the cover plate 314 can squeeze the base film 90 more uniformly, and poor contact between the back adhesive 70 on the base film 90 and the suction nozzle on the bearing groove 312 is avoided, thereby avoiding reduction of the adsorption force of the suction nozzle on the back adhesive 70, and improving the success rate of detachment of the back adhesive 70 from the base film 90.

In this embodiment, the magnet assembly is a plurality of magnet blocks 313 arranged at equal intervals along the length direction of the guide protruding strips 311, the magnets are embedded in the base 31, and the top surfaces of the magnet blocks 313 are flush with the top surface of the base 31. In other embodiments, the magnetic attraction group may be a bar-shaped magnet extending along the length direction of the guide protruding strip 311.
