Description

Technical Field

[0001] The utility model relates to the field of electronic processing and manufacturing equipment, in particular to a conductive cloth attaching and folding edge fixture. Background Art

[0002] Nowadays, camera modules have been widely used in electronic devices. Camera modules are usually composed of circuit boards, photosensitive chips, packages, lens assemblies, housings and other components. They are generally installed inside electronic devices, and the lenses and part of the housing extend out of the device to capture external images. The camera module may generate electromagnetic radiation during operation, and the exposed parts make the camera module susceptible to external static electricity and external electromagnetic interference. In particular, when the camera module housing is made of metal, the collected image will be abnormal or the camera will be damaged, so the camera module needs to be electrostatically shielded.

[0003] Conductive fabric is often used as a means of electrostatic shielding due to its excellent conductivity and electromagnetic shielding performance. It can be tightly wrapped around the periphery or key parts of the camera module to form an effective electromagnetic protection barrier, reducing interference to the outside world and sensitivity to internal circuits. Conductive fabric can also be used to ensure a good ground connection between components, helping to eliminate static electricity accumulation and protect components from damage by electrostatic discharge.

[0004] At present, during the production process of the camera module, it is necessary to align and fold a layer of conductive cloth on the camera module and attach it to the outer surface of the camera module. The existing technology generally uses manual placement of the camera module into the positioning groove, manually aligning the release film, and then using a press assembly to attach the conductive cloth on the release film to the camera module. This has low working efficiency, high work intensity, unstable bonding position and force, and poor consistency in the bending and attaching position and force control of the conductive cloth. Utility Model Content

[0005] The purpose of the utility model is to provide a conductive cloth attaching folding jig, aiming to solve the technical problems existing in the prior art of low working efficiency, high working intensity, unstable attaching position and force, and poor consistency in the position and force control of the conductive cloth bending attachment.

[0006] In order to solve the above technical problems, the utility model provides a conductive cloth attaching folding jig, comprising:

[0007] Base;

[0008] A positioning block, disposed on the base, wherein the positioning block is provided with a positioning groove for placing the material to be processed; and

[0009] The rotating member comprises a connecting portion and a bending portion, wherein the connecting portion is rotatably connected to the positioning block, the bending portion is adjacent to the positioning groove, and the rotating member can rotate around the connection between the connecting portion and the positioning block to flip the bending portion.

[0010] In the above-mentioned implementation, the positioning groove of the positioning block can limit the position of the conductive cloth and the camera module, so that the attachment position of the conductive cloth and the camera module is unified, and the rotating member includes a connecting portion and a bending portion, and the connecting portion and the positioning block are rotatably connected, driving the bending portion to rotate so that the conductive cloth is bent and attached to the camera module. The specific method of use is that the staff puts the conductive cloth into the positioning groove of the positioning block with the adhesive surface facing up, and then puts the camera module into the positioning groove of the positioning block, so that the bottom of the camera module fits with the conductive cloth, and rotates the rotating member so that the connecting portion drives the bending portion to rotate above the positioning block, and further bends the tail end of the conductive cloth and attaches it to the camera module, thereby achieving a stable bending and attachment position and force, and achieving consistency in the bending and attachment position and force control of the conductive cloth.

[0011] Preferably, it further comprises a fixing block, wherein the fixing block is mounted on the base, and the positioning block is mounted on the fixing block.

[0014] Limiting the position of the adsorption part helps to place the camera module in the positioning groove, limiting the position of the positioning groove of the positioning block and the adsorption part on the same axis, reducing the position offset between the positioning groove and the adsorption part, and the first adsorption hole passing through the adsorption part in the height direction helps to adsorb the conductive cloth, making the conductive cloth flat, without bending and fixed in position, further helping to improve the attachment position accuracy and achieve consistency in the attachment position of the conductive cloth.

[0015] Preferably, a vacuum groove is provided at one end of the adsorption member away from the positioning groove, and a negative pressure joint is provided at the base, and the negative pressure joint is connected to the vacuum groove.

[0016] The vacuum groove of the adsorption part is connected to the negative pressure joint to provide a vacuum environment inside the groove, so that the adsorption hole generates suction. The adsorption hole applies adsorption force to the part of the conductive cloth in the positioning groove, which helps to fix and flatten the conductive cloth.

[0017] Preferably, a support portion is provided at one end of the positioning groove, and the support portion is provided with a plurality of second adsorption holes.

[0018] The positioning groove is structurally divided into a main body and a bending and attaching part. The main body supports the main part of the conductive cloth and the camera module, and the supporting part supports the bending and attaching part of the conductive cloth and the camera module. The adsorption force of the second adsorption hole helps to make the bending and attaching part of the conductive cloth flat, without bending and fixed in position.

[0019] Preferably, the connecting portion is provided at one end or both ends of the positioning block, and an extension line of a rotation axis of the connecting portion passes through the positioning groove.

[0020] The rotating part is divided into two parts: a connecting part and a bending part. The connecting part is connected to one end or both ends of the positioning block, which helps to determine the rotation axis of the rotating part. The extension line of the rotation axis of the connecting part passes through the positioning groove, which helps to drive the bending part during rotation, accurately bend the tail end of the conductive cloth and attach it to the camera module, further helping to improve the attachment position accuracy and achieve consistency in the conductive cloth attachment position.

[0022] The third adsorption hole helps to fix the position of the conductive cloth part to be bent, and makes the conductive cloth part to be bent flat and without bending. The gas channel can be connected to the vacuum environment to provide the adsorption force of the third adsorption hole, which is further beneficial to fix the position of the conductive cloth part to be bent and make it flat and without bending, improve the position accuracy of the attachment, and achieve consistency in the bending and attachment position of the conductive cloth.

[0023] Preferably, a connecting piece is provided at one end of the rotating piece, and the connecting piece is communicated with the gas channel.

[0024] The connecting part is arranged on the rotating part, connecting the gas channel with the provided external vacuum environment, so that a vacuum environment is formed in the gas channel, and further a vacuum environment is formed in the third adsorption hole, providing adsorption force, and further achieving the position of the conductive cloth part to be bent to be fixed and flat without bending, thereby improving the attachment position accuracy and achieving consistency in the bending and attachment position of the conductive cloth.

[0025] Preferably, it further comprises a limiting member, which is arranged on the fixed block and is used to limit the rotation angle of the rotating member.

[0026] After the rotating part is flipped, the surface of the bent part will completely overlap with the surface of the positioning block.

[0039] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0040] In the description of the present invention, it should be understood that terms such as "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0041] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0042] In this embodiment, combined with Figure 1 , 2As shown in FIG. 3 , the present invention provides a conductive cloth attaching folding jig, which includes a base 10, a positioning block 20, an adsorption member 30 and a rotating member 40. The base 10 is the base on which all components are installed. A groove 11 is provided on the top of the base 10, and a threaded hole for connecting a negative pressure connector 60 is provided on the groove 11. The positioning block 20 is provided with a positioning groove 21 and a positioning hole 22 along the height direction, and a threaded hole for connecting the negative pressure joint 60 is provided at the bottom of the positioning block 20. It can be understood that the positioning groove 21 is matched with the shape of the camera module 80 but is larger in size. The positioning hole 22 is located on one side of the positioning block 20, and the positioning groove 21 is located on the top of the positioning block 20. The positioning groove 21 is divided into a main body 212 and a support part 213. The main body of the positioning groove 21 is coaxial with the positioning hole 22, and the support part 213 of the positioning groove 21 is adjacent to the positioning hole 22. In this embodiment, the size of the positioning groove 21 is larger than the positioning hole 22, and the positioning groove 21 and the positioning hole 22 are stepped to achieve the positioning of the conductive cloth 70 and the camera module 80, thereby further improving the accuracy of the attachment position. The rotating member 40 includes a connecting portion 41 and a bending portion 42. The connecting portion 41 is rotatably connected to the positioning block 20. When driven by an external force, the rotating member 40 can rotate around the connection between the connecting portion 41 and the positioning block 20, so that the portion to be bent of the conductive cloth 70 can be bent and attached to the camera module 80.

[0043] In addition, the positioning block 20 can also be made of a retractable material. After unrestricted flipping so that the surface of the bent portion completely overlaps with the surface of the positioning block, if the external force still exists, it can buffer the additional force and excessive flipping of the rotating part 40 to a certain extent, thereby achieving the consistency requirement of force control.

[0044] In this embodiment, a fixing block 50 is further included. The fixing block 50 is provided with a first through hole 51 and a plurality of threaded holes. The fixing block 50 is connected to the base 10 with bolts. The positioning block 20 is connected to the fixing block 50 with bolts. The first through hole 51 is coaxial with the positioning groove 21.

[0045] It is understandable that in other embodiments, the first through hole 51 of the fixed block 50 may not be coaxial with the positioning groove 21. Further, the first through hole 51 may not be provided. In this case, the fixed block 50 is only used as an auxiliary positioning of the positioning block 20 and the adsorption component 30. Furthermore, the fixed block 50 may not be provided, and the positions of the positioning block 20 and the adsorption component 30 on the base shall prevail.

[0046] In this embodiment, please refer to Figure 3 and Figure 4As shown, an adsorbent 30 is provided at the bottom of the positioning groove 21 of the positioning block 20, and the adsorbent 30 passes through the positioning hole 22 of the positioning block 20 and is installed on the groove 11 at the top of the base 10. The adsorbent 30 is provided with a plurality of first adsorbent holes 32 that penetrate along the height direction of the adsorbent 30. The positions of the groove 11 at the top of the base 10, the positioning groove 21 of the positioning block 20 and the adsorbent 30 are restricted on the same axis, further limiting the position of the adsorbent 30 and improving the accuracy and consistency of the attachment position of the conductive cloth 70.

[0047] In addition, please refer to Figure 3 As shown, the adsorption member 30 can also be passed through the first through hole 51 of the fixing block 50 to fix the positions of all components on the base 10, improve the stability of the vacuum condition, help to adsorb the conductive cloth 70, and further help to make the conductive cloth 70 flat and without bending.

[0048] For details, please refer to Figure 3 and Figure 4 As shown, a vacuum groove 31 is provided at one end of the adsorption member 30 away from the positioning groove 21, that is, the bottom of the adsorption member 30. It can be understood that the size of the vacuum groove 31 is smaller than the size of the groove 11. The negative pressure joint 60 is connected with the threaded hole of the groove 11 of the base 10. The negative pressure joint 60 forms a vacuum environment between the vacuum groove 31 and the groove 11 through the threaded hole, so that the first adsorption hole 32 of the adsorption member 30 generates an adsorption force, thereby realizing the fixation and flattening of the conductive cloth 70 and improving the attachment effect of the conductive cloth 70.

[0049] In addition, a sealing member such as a rubber gasket may be provided between the adsorption member 30 and the groove 11 to facilitate the formation of a vacuum environment.

[0050] In addition, the adsorption component 30 may not pass through the first through hole 51 of the fixed block 50. In this case, the fixed block 50 can omit the first through hole 51, so that the vacuum groove 31 of the adsorption component 30 and the groove 11 on the top of the base 10 can form a vacuum environment to ensure that there is no offset between the adsorption component 30 and the positioning block 20.

[0051] In this embodiment, please refer to Figure 5 and Figure 6 As shown, a support portion 213 is provided at one end of the positioning groove 21 near the bending portion 42, and the support portion 213 is used to support the position of the camera module 80 to be bent and adsorbed by the conductive cloth 70. It can be understood that the shape and structure of the support portion 213 change with the camera module 80. A plurality of second adsorption holes 211 are provided on the support portion 213 of the positioning groove 21, and an internal channel 23 connected to the second adsorption holes 211 is provided inside the positioning block 20. A threaded hole for connecting the negative pressure joint 60 is provided at the bottom of the positioning block 20. The negative pressure joint 60 is connected to the internal channel 23 to form a vacuum environment, so that the second adsorption holes 211 generate adsorption force.

[0052] In addition, instead of setting the internal channel 23 connected to the negative pressure connector 60 inside the positioning block 20, a groove can be set at the second adsorption hole 211 at the bottom of the positioning block 20, and the groove is connected to the negative pressure connector 60 to form a vacuum environment to provide adsorption force.

[0053] In this embodiment, please refer to Figure 1 and Figure 2 As shown, the connecting part 41 is connected to both ends of the positioning block 20. When the connecting part 41 rotates, the extension line of the rotation axis passes through the positioning groove 21. When rotating with the axis, the bending part 42 can accurately bend the part of the conductive cloth 70 to be bent and attach it to the camera module 80.

[0054] In addition, in addition to the connection between the connecting portion 41 and both ends of the positioning block 20, it can also be connected to only one end of the positioning block 20. Further, the rotating member can be independently provided to achieve consistency in the bending and attaching position of the conductive cloth.

[0055] In this embodiment, please refer to Figure 7 and Figure 8 As shown, the bending portion 42 is also provided with a plurality of third adsorption holes 421, and the third adsorption holes 421 are arranged along the height direction of the bending portion 42, and the third adsorption holes 421 are located at one end of the bending portion 42 close to the positioning groove 21. A gas channel 44 is also provided inside the rotating part 40, and the gas channel 44 is connected to the third adsorption holes 421 to ensure that the third adsorption holes 421 can generate adsorption force, so as to realize the flatness and position fixation of the conductive cloth to be bent and attached.

[0056] In addition, the shapes and structures of the connecting portion 41 and the bending portion 42 can be changed, so that the bending portion 42 can bend the conductive cloth 70 with a small offset and attach it to the camera module 80 .

[0057] For details, please refer to Figure 1 As shown, a connecting member 43 is provided at one end of the rotating member 40, that is, the connecting member 43 is arranged at one end of the connecting portion 41, and the connecting member 43 is connected to the gas channel 44 inside the rotating member 40. The connecting member 43 can provide a vacuum environment for the gas channel 44 of the rotating member 40 together with an external device, so that the third adsorption hole 421 generates an adsorption force.

[0058] In this embodiment, the rotating member 40 also includes a limit member not shown in the figure. In this embodiment, the limit member is a limit pin. The limit member can be set on the contact surface of the fixed block 50 that can contact the rotating member 40. When the rotating member 40 flips over to the fixed block 50, that is, the bending portion 42 flips over to the positioning block 20, so that the part of the conductive cloth 70 to be bent and attached is bent and attached to the camera module 80, the limit member restricts the rotating member 40 from continuing to flip, thereby protecting the camera module 80 from being affected by additional force, thereby achieving force control consistency of the bending and attachment of the conductive cloth 70.

[0059] In addition, the limiter can also be set on the contact surface of the rotating member 40 that can contact the fixed block 50 or the contact surface of the bending portion 42 and the positioning block 20, so as to limit the rotating member 40 from continuing to flip and achieve the force control consistency of the bending and attachment of the conductive cloth 70.

[0060] In addition, the limiting member may also be a limiting block, etc., so as to limit the rotating member 40 from further turning over.

[0061] The specific application process of the utility model is as follows:

[0062] Place the conductive cloth with the adhesive surface facing up in the positioning groove of the positioning block and on the adsorption piece. The negative pressure joint is connected to the vacuum groove, and the vacuum environment generated causes the adsorption holes of the adsorption piece to generate suction. The adsorption holes make the conductive cloth flat and fix the position of the conductive cloth. Place the camera module in the positioning groove and on the conductive cloth, so that the bottom of the camera module fits with the adhesive surface of the main part of the conductive cloth. The connecting part of the rotating part is driven by an external force to rotate with the connection between the connecting part and the positioning block as the axis. The connecting part drives the bending part, and the bending part rotates to the top of the positioning block. The bending part bends the part of the conductive cloth to be bent and attached, and makes the part fully attached to the camera module, then the rotating part returns to its position, and the camera module is taken out to complete the folding and attachment of the conductive cloth.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
