Description

Technical Field

[0001] This invention relates to the field of camera manufacturing technology, and in particular to a bending fixture for camera module FPC. Background Technology

[0002] Currently, all camera modules contain FPCs. During the production process, the FPCs need to be bent into a specified shape to facilitate the subsequent production and assembly of the camera modules.

[0003] As per the instruction manual Figure 1-2 In this process, one end of FPC1-2 is located at the bottom of camera module 1-1, and the other end is connected to PCB1-3. During production, FPC1-2 needs to be bent three times. Specifically, the first bend is performed at the first bend angle 1-21, the second bend at the second bend angle 1-22, and the third bend at the third bend angle 1-23, thus bending FPC1-2 into a specified shape (e.g., ...). Figure 4 As shown), FPC1-2 and PCB1-3 are ultimately arranged around camera module 1-1 (as shown). Figure 3 As shown), even if FPC1-2 is attached to two adjacent first wall surfaces 1-12 and second wall surfaces 1-13 of camera module 1-1 (see... Figure 1 ).

[0004] Because the three corners of FPC1-2 need to be bent from multiple angles, but in actual production, existing fixtures are limited by space and angle constraints, making it difficult to bend FPC1-2 from multiple angles. Therefore, grippers or manual assistance are generally required to complete the bending of the three corners of FPC1-2, resulting in cumbersome operation. Furthermore, as... Figure 2 As shown, the third bend position 1-23 is located in the middle of FPC1-2. During bending, the electronic components 1-11 and other edge structures on the camera module 1-1 will create some obstruction and interference during the bending process of the third bend position 1-23. That is, if the bending position is not accurate when bending FPC1-2 at the third bend position 1-23, the electronic components 1-11 and other edge structures on the camera module 1-1 will hit and damage FPC1-2. Therefore, it is difficult for the fixture to determine the position of the third bend position 1-23, i.e., it is impossible to determine the bending reference point, thus affecting the bending work. In addition, after the FPC is bent through the existing production fixture, there will be a rebound phenomenon, making it difficult to form a stable shape, which will affect subsequent production assembly.

[0005] Therefore, it is necessary to provide a technical solution that can bend the three corners of an FPC and ensure the bending effect. Summary of the Invention

[0006] This invention proposes a camera module FPC bending fixture to solve the problems of existing production fixtures which are difficult to bend FPCs from multiple angles, require external assistance and thus cause operational inconvenience, and also have the problems of difficulty in determining the reference for the bending angle position of the FPC during the bending process, and the FPC rebounding after bending, affecting the bending effect.

[0007] The technical solution adopted in this invention is as follows: a camera module FPC bending fixture, the camera module includes a first wall and a second wall adjacent to the first wall, the camera module FPC bending fixture includes: a base plate, a base, a slider, a bending block and an extrusion block; The base is disposed on the base plate. The base is provided with a receiving groove and a limiting groove located on the side of the receiving groove and communicating with the receiving groove. The receiving groove is used to place the camera module and allow the FPC on the camera module to extend into the limiting groove. The bending block is rotatably mounted on the base plate, and the bending block rotates towards or away from the receiving groove; the extrusion block is detachably mounted on the upper end face of the bending block; the slider is mounted in the limiting groove, and the slider can move towards the receiving groove. The PCB, after being rotated 180 degrees counterclockwise, is clamped at the upper surface of the bending block by the bending block to bend the FPC at its first corner. The slider moves toward the camera module and bends the FPC, which extends into the limiting groove, upward and presses it against the first wall of the camera module to bend the FPC at its second corner. The bending block and the pressing block rotate together toward the camera module and bend the FPC against the second wall of the camera module to bend the FPC at its third corner, and then bend the first corner again to shape it. The first wall faces the limiting groove and is adjacent to the second wall.

[0008] In one embodiment, the extrusion block has a mounting groove for placing a PCB on its end face facing the bending block, and the upper end face of the bending block has at least one protrusion for fixing the PCB; the mounting groove and the protrusion cooperate to stably place the PCB between the bending block and the extrusion block.

[0009] In one embodiment, a slot is provided on the upper end face of the bending block facing the camera module. The slot is used to fit the edge structure of the camera module so that the pressing block can be tightly attached to the second wall of the camera module.

[0010] In one embodiment, a positioning strip is provided on the upper end face of the bending block, and a positioning hole is provided on the end face of the extrusion block facing the bending block. The positioning strip is inserted into the positioning hole to position the extrusion block and the bending block.

[0011] In one embodiment, the slider is provided with a through groove, and the extension direction of the through groove is towards the receiving groove; a limiting block is provided at the limiting groove, the limiting block is disposed on the base, and the limiting block is engaged in the through groove so that the slider is stably disposed on the base and can move.

[0012] In one embodiment, a first magnetic element is provided on the side of the slider away from the receiving groove, and a second magnetic element is provided on the side of the slider close to the receiving groove. Both the first magnetic element and the second magnetic element can be magnetically attracted to the limiting block.

[0013] In one embodiment, a rotating shaft is rotatably provided on the base plate; a protrusion is provided on one side of the bending block, and the protrusion is sleeved on the rotating shaft to rotatably mount the bending block on the base plate; The base has a clearance groove on the side near the bending block, and the rotating shaft and the protrusion are both located in the clearance groove so that the bending block can rotate and fit tightly against the side wall of the base.

[0014] In one embodiment, both the extrusion block and the slider are provided with threaded holes, and handles are installed on the threaded holes. The handles are used to drive the extrusion block and the slider to move, respectively.

[0015] In one embodiment, a magnetic block is provided on the end face of the bending block facing the base, and the magnetic block is magnetically attracted to the side wall of the base to fix the bending block.

[0016] In one embodiment, a third magnetic block is provided on the end face of the extrusion block facing the bending block, and the third magnetic block is magnetically attracted to the upper end face of the bending block to fix the extrusion block and the bending block.

[0017] The beneficial effects of this invention are: In this application, the PCB of the camera module is rotated 180° counterclockwise and placed between the bending block and the extrusion block. The bending block and the extrusion block work together to clamp and fix the PCB, and pre-bend the first corner of the FPC. Then, the slider is driven to move towards the camera module, bending the FPC inserted into the limiting groove upward and pressing it against the first wall of the camera module, thereby bending the second corner of the FPC. At this time, the slider is close to the first wall of the camera module and presses and fixes the side of the FPC containing the second corner. At this time, the third corner of the FPC corresponds to the corner of the camera module, thus determining the position of the third corner. Then, the bending block and the extrusion block are rotated, so that the bending block and the extrusion block bend and press the side of the FPC containing the first corner against the second wall of the camera module, thereby bending the third corner at the corner of the camera module. At the same time, the FPC structure corresponding to the first corner is extruded again. Therefore, the first bend can be bent and shaped again. In addition, the FPC is tightly pressed onto the side wall of the camera module by the bending block, the extrusion block and the slider. After the FPC is bent and shaped, the slider is first driven to move away from the camera module. Then, the extrusion block on the upper end of the bending block is removed. At this time, the position of the bending block does not move. Then, the bent and shaped camera module is taken out. Finally, the bending block is rotated away from the receiving groove and returned to its original position. This completes the bending and shaping of the product and removes it. This can prevent the FPC from rebounding after bending and ensure the bending effect. Therefore, in this application, the bending work of the FPC can be performed at three positions by the cooperation between the bending block, the extrusion block and the slider. It does not need to rely too much on external assistance. Moreover, the bending fixture of this application has a simple structure, is easy to operate, can determine the position of each bending point, and the FPC shape is stable after bending, avoiding the FPC rebounding after bending, which can ensure the bending effect and guarantee the bending quality of the product.

Detailed Implementation

[0020] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] Please see Figure 5-7 This embodiment provides a camera module FPC bending fixture, including: a base plate 1, a base 2, a slider 6, a bending block 3, and an extrusion block 4; the base 2 is disposed on the base plate 1, and the base 2 is provided with a receiving groove 201 and a limiting groove 202 located on the side of the receiving groove 201 and communicating with the receiving groove 201. The receiving groove 201 is used to place the camera module 1-1 and to allow the FPC 1-2 on the camera module 1-1 to extend into the limiting groove 202 (see...). Figure 15 At this time, the slider 6 does not move towards the receiving groove 201 and bend the FPC1-2, nor does it bend the second bend position 1-22; the bending block 3 is rotatably mounted on the base plate 1, and the bending block 3 rotates close to or away from the receiving groove 201, that is, the bending block 3 rotates close to or away from the second wall surface 1-13 of the camera module 1-1; the extrusion block 4 is detachably mounted on the upper end face of the bending block 3; the slider 6 is mounted in the limiting groove 202, and the slider 6 can move towards the receiving groove 201, that is, the slider 6 can move towards the first wall surface 1-12 of the camera module 1-1.

[0022] It is worth noting that the first wall 1-12 and the second wall 1-13 are two adjacent walls of the camera module 1-1 (see [link]). Figure 1After the camera module 1-1 is placed into the receiving slot 201, the first wall surface 1-12 faces the limiting slot 202, and the second wall surface 1-13 faces one side of the bending block 3 (see...). Figure 15 ).

[0023] The bending steps for FPC1-2 in this embodiment are as follows: First, place the camera module 1-1 in the receiving slot 201 (see...). Figure 15 Then, after rotating the PCB1-3 of the camera module 1-1 counterclockwise by 180°, place the PCB1-3 on the upper surface of the bending block 3 (see...). Figure 16-17 Next, the extrusion block 4 is installed. The bending block 3 and the extrusion block 4 cooperate to clamp and fix PCB1-3. During the counter-clockwise rotation of PCB1-3, the first bend corner 1-21 of FPC1-2 can be pre-bent. Then, the slider 6 is driven to move towards the first wall surface 1-12 of the camera module 1-1, bending and pressing the FPC1-2, which extends into the limiting groove 202, onto the first wall surface 1-12 of the camera module 1-1 (see...). Figure 16 , 17 This completes the bending operation of the second corner position 1-22 of FPC1-2 (see...). Figure 18 At this point, slider 6 is pressed tightly against the first wall 1-12 of camera module 1-1 and presses and fixes the side of PFC1-2 containing the second corner position 1-22. At this time, the third corner position 1-23 of FPC1-2 corresponds to the corner of camera module 1-1 (see...). Figure 16 This corner corresponds to the intersection of the first wall surface 1-12 and the second wall surface 1-13 of the camera module 1-1, that is, the intersection of two adjacent walls. This location determines the position of the third bend position 1-23 and the reference point for the bend. The first bend position 1-21 is located at the edge of the end face of the bending block 3 facing the camera module 1-1 (see...). Figure 16 Then, rotate the bending block 3 and the pressing block 4 to bend and press the side of FPC1-2 containing the first folded corner 1-21 onto the second wall surface 1-13 of the camera module 1-1 (see...). Figure 17 This allows the third bend position 1-23 to bend at the corner of camera module 1-1 (see...). Figure 3 Simultaneously, bending block 3 and pressing block 4 bend and press the FPC1-2 structure corresponding to the first folding corner 1-21 onto the second wall surface 1-13 of the camera module 1-1, thus allowing the first folding corner 1-21 to be pressed again (see...). Figure 17The bending process involves bending the first corner 1-21 again (the first corner 1-21 of FPC1-2 was pre-bent during the counterclockwise rotation of PCB1-3) to enhance the bending effect. Subsequently, the bending block 3, the extrusion block 4, and the slider 6 are left to stand for a period of time, allowing the entire camera module FPC bending fixture to continuously extrude pressure on FPC1-2. After FPC1-2 has completed bending, the slider 6 is first driven to move away from the camera module 1-1. Then, the extrusion block 4 on the upper surface of the bending block 3 is removed. At this time, the position of the bending block 3 remains unchanged. Then, the bent and shaped camera module 1-1 is taken out. Finally, the bending block 3 is rotated away from the receiving groove 201 and returned to its original position. This completes the bending and shaping of the product and removes it. This prevents FPC1-1 from rebounding after bending and ensures the bending effect.

[0024] Therefore, in this embodiment, the bending block 3, the extrusion block 4 and the slider 6 cooperate with each other to bend the three positions of FPC1-2, namely the corner positions, without relying too much on external aids. Moreover, the bending fixture of this application has a simple structure and is easy to operate. It can determine the position of each bending point and the reference point for bending. The shape of FPC1-2 is stable after bending, avoiding FPC rebound after bending, which can ensure the bending effect and guarantee the bending quality of the product.

[0025] For details, please refer to Figure 5-9 Both the base plate 1 and the base 2 are square structures, and the cross-sectional area of ​​the base plate 1 is larger than that of the base 2, so that the base 2 can be mounted on the base plate 1; wherein, a locking hole 103 is provided on the base plate 1, and a locking strip 205 is provided on the lower end face of the base 2 (e.g., Figure 8 As shown, the base 2 is positioned by inserting the clip 205 into the clip hole 103, allowing it to be quickly placed on the base plate 1. Preferably, two clips 205 are provided, distributed on both sides of the lower end face of the base 2, and two clip holes 103 are also provided. The clips 205 and clip holes 103 correspond one-to-one. The limiting effect of the two clips 205 allows the base 2 to be stably placed on the base plate 1. Furthermore, several first mounting holes 102 are provided on the base plate 1, and several second mounting holes 203 are provided on the base 2, penetrating the base 2. The first mounting holes 102 and second mounting holes 203 correspond one-to-one, so that screws can be installed in the first mounting holes 102 and second mounting holes 203 to fix the base plate 1 and the base 2.

[0026] A receiving groove 201 is provided on the upper surface of the base plate 1 and on one side. The structure of the receiving groove 201 corresponds to that of the camera module 1-1, so as to place the camera module 1-1 accordingly. At the same time, the receiving groove 201 penetrates the side wall of the base 2 facing the bending block 3, so that after the camera module 1-1 is installed in the receiving groove 201, the second wall 1-13 of the camera module 1-1 is exposed. In fact, the first wall 1-12 adjacent to the second wall 1-13 is also exposed when the slider 6 is not moving in close contact. In addition, the other two walls of the camera module 1-1 are in contact with the side wall of the receiving groove 201. The limiting groove 202 is located on the side of the receiving groove 201 and communicates with the receiving groove 201. The limiting groove 202 also penetrates the side wall of the base 2 facing the bending block 3. Furthermore, the bottom surface of the limiting groove 202 is higher than the bottom surface of the receiving groove 201 (see Figure 8 This forms a limiting structure, allowing the camera module 1-1 to be stably placed in the receiving groove 201. The slider 6 is movably mounted in the limiting groove 202, and the side wall of the slider 6 facing the camera module 1-1 has a push-fold surface 600 (see...). Figure 6 The slider 6 contacts the first wall 1-12 of the camera module 1-1 at the folding surface 600 to bend the second corner 1-22 of the FPC 1-2. The area of ​​the folding surface 600 is larger than the area of ​​the first wall 1-12 to ensure that the slider 6 completely covers and presses on the first wall 1-12, thus ensuring the bending effect of the FPC 1-2.

[0027] The bending block 3 is generally square in shape and is set on the base plate 1 and located on the side of the receiving groove 201. The side wall of the bending block 3 near the receiving groove 201 is the bending surface 306. During the rotation of the bending block 3, the bending surface 306 can rotate to move closer to or away from the base 2. Moreover, when the bending block 3 is close to the camera module 1-1, the bending surface 306 can be pressed tightly against the wall of the base 2.

[0028] The extrusion block 4 has a square structure and its size corresponds to the upper end face of the bending block 3. The side wall of the extrusion block 4 near the camera module 1-1 is the extrusion surface 400. During the rotation of the bending block 3, the extrusion surface 400 can rotate to move closer to or away from the second wall 1-13 of the camera module 1-1. Moreover, when the bending block 3 is close to the camera module 1-1, the extrusion surface 400 of the extrusion block 4 can be pressed tightly against the second wall 1-13 of the camera module 1-1 to cooperate with the bending block 3 to bend the first fold position 1-21 and the third fold position 1-23 of the FPC 1-2.

[0029] For further details, please see Figure 6 , 7Components 12-14 and 16: The extrusion block 4 has a mounting groove 405 for placing PCB 1-3 on its end face facing the bending block 3; the upper end face of the bending block 3 has at least one protrusion 303 for fixing PCB 1-3; the mounting groove 405 and the protrusion 303 cooperate to stably place PCB 1-3 between the bending block 3 and the extrusion block 4. Specifically, the protrusion 303 engages with the corresponding hole in PCB 1-3 (see...). Figure 16 This allows PCB1-3 to be stably placed on the upper surface of bending block 3 after being rotated 180° counterclockwise, thereby changing the position of PCB1-3 and avoiding obstruction of electronic components 1-11 of camera module 1-1, preventing electronic components 1-11 from blocking FPC1-2 and affecting the bending operation. Preferably, two protrusions 303 are provided and distributed on the upper surface of bending block 3. The limiting effect of the two protrusions 303 allows PCB1-3 to be placed more stably on the upper surface of bending block 3. The mounting groove 405 is located on the lower surface of extrusion block 4 and corresponds to the structure of PCB1-3. 4. When installed on the bending block 3, PCB1-3 is placed in the mounting slot 405 to ensure that PCB1-3 can be stably placed between the bending block 3 and the extrusion block 4. One side of the mounting slot 405 has a slot 406, which is used to fit and place FPC1-2. After PCB1-3 is placed in the mounting slot 405, FPC1-2 extends to the outside at the slot 406, and the first bend position 1-21 of FPC1-2 is located at the slot 406. Therefore, through the cooperation of the mounting slot 405 and the protrusion 303, PCB1-3 can be stably clamped between the bending block 3 and the extrusion block 4.

[0030] In addition, a mating hole 403 is provided on the extrusion block 4 and located in the mounting groove 405 (see Figure 14 The mating holes 403 and the protrusions 303 correspond one-to-one, and the protrusions 303 can be inserted into the mating holes 403 to prevent PCB1-3 from falling off the protrusions 303, thereby further ensuring the fixing effect of PCB1-3 on the bending block 3.

[0031] For further details, please refer to Figure 7 , 12 -13. A slot 302 is provided on the upper end face of the bent block 3 facing the camera module 1-1. The slot 302 passes through the bent surface 306 of the bent block 3, and extends to both ends at the bent surface 306 to penetrate the two adjacent walls of the bent surface 306 (see...). Figure 13 ); wherein, when the bending block 3 moves to the second wall 1-13 of the camera module 1-1 to bend the FPC 1-2, the electronic component 1-11 on the camera module 1-1 is accommodated by the slot 302 (see Figure 1And extends to both ends through the card slot 302 at the bent surface 306, the card slot 302 adapts to accommodate the edge structure of the camera module 1-1 (see Figure 1 Ultimately, the bending surface 306 of the bending block 3 can be tightly attached to the side wall of the base 2, thereby allowing the extrusion block 4 to be tightly attached to the second wall 1-13 of the camera module 1-1, thus ensuring the bending effect of FPC 1-2. Furthermore, through the card slot 302 and the card slot 302 extending to both ends at the bending surface 306, the electronic components 1-11 and edge structures on the camera module 1-1 can be effectively avoided.

[0032] For further details, please refer to Figure 6 , 12 -14. A positioning strip 301 is provided on the upper end face of the bending block 3, and a positioning hole 402 is provided on the end face of the extrusion block 4 facing the bending block 3. The positioning strip 301 is inserted into the positioning hole 402 to position the extrusion block 4 and the bending block 3. Specifically, the positioning strip 301 and the positioning hole 402 correspond in shape. In this embodiment, the positioning strip 301 is set as a rounded prism, while the positioning hole 402 is circular to fit the positioning strip 301. Preferably, there are two positioning strips 301, which are distributed on both sides of the upper end face of the bending block 3; there are two positioning holes 402, which are distributed on the lower end face of the extrusion block 4; the positioning strips 301 and the positioning holes 402 are matched one-to-one. Through the limiting of the two positioning strips 301, the extrusion block 4 can be stably placed on the bending block 3.

[0033] For further details, please refer to Figure 14 A third magnetic block 404 is provided on the end face of the extrusion block 4 facing the bending block 3. The third magnetic block 404 can be magnetically attracted to the upper end face of the bending block 3 to fix the extrusion block 4 onto the bending block 3. Specifically, the third magnetic block 404 is a component that can generate magnetic force. A magnetic component or metal component that can magnetically engage with the third magnetic block 404 is provided on the upper end face of the extrusion block 4, or the bending block 3 is set as a metal component that can magnetically engage with the third magnetic block 404, so that the third magnetic block 404 can be magnetically attracted to the bending block 3 to fix the extrusion block 4 and the bending block 3.

[0034] For further details, please refer to Figure 6-8 12-13, A rotating shaft 305 is rotatably mounted on the base plate 1. A protrusion 307 is provided on one side of the bending block 3. The protrusion 307 is sleeved on the rotating shaft 305, so that the bending block 3 is rotatably mounted on the base plate 1 through the cooperation of the rotating shaft 305 and the protrusion 307. A relief groove 204 is provided on the side of the base 2 near the bending block 3. The rotating shaft 305 and the protrusion 307 are both located in the relief groove 204, so that the bending block 3 can rotate and fit tightly against the side wall of the base 2. Specifically, a through hole 101 is provided on the base plate 1, and the rotating shaft 305 is rotatably mounted in the through hole 101. The side of the bending block 3 is provided with a protrusion 307 (e.g., Figure 13 As shown, the protrusion 307 has a hole that passes through the upper and lower end faces. The protrusion 307 is fitted onto the rotating shaft 305 through the hole, and the bending block 3 is then installed onto the rotating shaft 305. The relief groove 204 is provided on the wall of the base 2 near the bending block 3 and is recessed. The relief groove 204 avoids the position of the rotating shaft 305 to ensure the rotation effect of the bending block and to ensure that the bending block 3 can be tightly attached to the side wall of the base 2 when rotating, thereby ensuring the bending effect of FPC1-2.

[0035] For further details, please refer to Figure 5 , 13 A magnetic block is provided on the end face of the bending block 3 facing the base 2. The magnetic block is magnetically attracted to the side wall of the base 2 to fix the bending block 3 to the side wall of the base 2. Specifically, the magnetic block includes a first magnetic block 304 and a second magnetic block 308. The first magnetic block 304 is provided on the bending surface 306 of the bending block 3. When the extrusion block 4 and the bending block 3 rotate to the second wall surface 1-13 of the camera module 1-1 to extrude and bend the FPC 1-2, the first magnetic block 304 can be magnetically attracted to the side wall of the base 2 to fix the bending block 3, so that the bending block 3 can be stably attached to the side wall of the base 2, and the extrusion block 4 can be stably attached to the second wall surface 1-13 of the camera module 1-1 to ensure the bending effect. Moreover, when the external force is removed, the extrusion block 4 can be kept in place by the magnetic attraction of the first magnetic block 304. The FPC1-2 is stably compressed and bent; the second magnetic block 308 is located on the other side of the bending block 3. This side can fit against the side wall of the base 2 when the bending surface 306 is away from the FPC1-2. Therefore, when the FPC1-2 does not need to be compressed, the bending block 3 is magnetically fixed to the side wall of the base 2 by the second magnetic block 308, that is, the bending block 3 is placed on one side of the receiving groove 201 to prevent the bending block 3 from affecting the camera module 1-1 being placed into the receiving groove 201 before the bending work is prepared; furthermore, two of the first magnetic block 304 and the second magnetic block 308 are provided to further improve the fixing effect.

[0036] It is worth mentioning that the first magnetic block 304 and the second magnetic block 308 are components that can generate magnetic force, such as magnets, lodestones, electromagnets, etc. Then, a magnetic component or metal component that can magnetically attract and cooperate with the magnetic block is provided on the side wall of the base 2 facing the bending block 3, or the base 2 is set as a metal component that can magnetically attract and cooperate with the magnetic block, so that the first magnetic block 304 and the second magnetic block 308 can be magnetically attracted to the base 2, thereby fixing the bending block 3.

[0037] For further details, please refer to Figure 5-610-11, A through groove 601 is provided on the slider 6, and the extension direction of the through groove 601 faces the receiving groove 201; a limiting block 8 is provided at the limiting groove 202, the limiting block 8 is provided on the base 2, and the limiting block 8 is engaged in the through groove 601 to make the slider 6 stably set on the base 2. Specifically, the through groove 601 penetrates the upper and lower end faces of the slider 6, and the through groove 601 has a certain length and is set in the direction of the receiving groove 201; the limiting block 8 is cylindrical, and the limiting block 8 is engaged in the through groove 601 to limit the movement distance of the slider 6, and through the cooperation of the limiting block 8 and the through groove 601, the slider 6 can be stably installed and moved on the base 2, ensuring that the slider 6 can move to the first wall surface 1-12 of the camera module 1-1 to perform bending work on the FPC 1-2. Preferably, two through slots 601 are provided and distributed on both sides of the slider 6; two limiting blocks 8 are provided and distributed at intervals in the limiting slot 202; wherein, the limiting blocks 8 are inserted into the through slots 601 one by one, and the limiting blocks 8 can make the slider 6 more stably placed in the limiting slot 202 and make the slider 6 move stably and directly.

[0038] For further information, please refer to [link / reference]. Figure 5-610-11, A first magnetic element 602 is provided on the side of slider 6 away from the receiving groove 201, and a second magnetic element 603 is provided on the side of slider 6 near the receiving groove 201. Both the first magnetic element 602 and the second magnetic element 603 can be magnetically attracted to the limiting block 8. Specifically, the second magnetic element 603 is provided on the push-bend surface 600 of slider 6, and corresponds to the through groove 601 on slider 6 near the second bend position 1-22. The first magnetic element 602 is provided on the wall surface of slider 6 opposite to the push-bend surface 600, and also corresponds to the through groove 601 on slider 6 near FPC1-2. During the operation of slider 6, when the push-bend surface 600 of slider 6 is in close contact with the first wall surface 1-12 of camera module 1-1, the limiting block 8 is located on the side of through groove 601 away from the receiving groove 201. The first magnetic component 602 can be magnetically attached to the limiting block 8 to fix the slider 6, so that it can be stably pressed onto the first wall surface 1-12. After the bending work is completed, the limiting block 8 is moved away from the first wall surface 1-12 of the camera module 1-1. At this time, the limiting block 8 can be located on the side of the through groove 601 close to the receiving groove 201. Then, the second magnetic component 603 can be magnetically attached to the limiting block 8 to fix the limiting block 8, so that it is in the preparation state for bending work, preventing it from sliding and affecting the placement of the camera module 1-1 into the receiving groove 201. Preferably, two of each of the first magnetic element 602 and the second magnetic element 603 are provided. One of the two first magnetic elements 602 is located on the side wall opposite to the push-bend surface 600, and the other first magnetic element 602 is located on the side wall adjacent to the push-bend surface 600, with both first magnetic elements 602 corresponding to the same limiting block 8. Similarly, one of the two second magnetic elements 603 is located on the push-bend surface 600, and the other is located on the side wall adjacent to the push-bend surface 600, with both first magnetic elements 602 corresponding to the same limiting block 8. The two first magnetic elements 602 and the two second magnetic elements 603 enhance the magnetic adsorption effect on the limiting block 8, thereby improving the fixing effect and bending effect of the slider 6.

[0039] It is worth mentioning that the first magnetic component 602 and the second magnetic component 603 are both components that can generate magnetic force, such as magnets, lodestones, electromagnets, etc. Then, the limiting block 8 is set as a magnetic component or metal component that can magnetically cooperate with the first magnetic component 602 and the second magnetic component 603, so that the first magnetic component 602 and the second magnetic component 603 can be magnetically attracted to the limiting block 8 to fix the slider 6.

[0040] Furthermore, both the extrusion block 4 and the slider 6 are provided with threaded holes, and handles are installed on the threaded holes. The handles are used to drive the extrusion block 4 and the slider 6 to move, respectively.

[0041] For details, please refer to Figure 5-614. The threaded hole on the extrusion block 4 is the first threaded hole 401, and the handle installed on the first threaded hole 401 is the first handle 5. The first threaded hole 401 has an internal thread, and the lower end of the first handle 5 is provided with an external thread. The internal thread and the external thread are engaged to detachably install the first handle 5 in the first threaded hole 401. The first handle 5 provides a position for easy clamping or manual holding, thereby facilitating the rotation of the extrusion block 4 and the bending block 3.
