It should be understood that the specific implementation manners described herein are only for explaining and illustrating the present invention, and are not used to limit the present invention.

[0039] This embodiment provides an FPC flexible cable bending and shaping device.

[0040] Please refer to Figure 1 、 Figure 2 、 Figure 10 and Figure 11 , Figure 1 which show the structural schematic diagrams of this embodiment, Figure 2 which shows the structural schematic diagram of the base 1 of this embodiment, Figure 10 which shows the structural schematic diagram of the FPC flexible cable 101 to be bent folded on the heating pressing block 6 of this embodiment, Figure 11 which shows the connection schematic diagram of the shaping pressing block 9 and the second extrusion block 7 of this embodiment.

[0041] In this embodiment, referring to Figure 1 、 Figure 11 and Figure 12, The FPC flexible cable bending and shaping device includes a base 1, a module pressing block 2, a supporting component, and a bending component.

[0042] A card slot 11 for placing the camera module 100 is provided on the base 1; the module pressing block 2 is detachably mounted on the base 1, where the module pressing block 2 covers part of the card slot 11 and can fix the camera module 100 in the card slot 11 to place it stably; the side wall of the module pressing block 2 for placing the FPC flexible cable 101 to be bent is the placement surface 21; and since the module pressing block 2 only covers part of the card slot 11 to expose the FPC flexible cable 101 on the camera module 100, the FPC flexible cable 101 to be bent on the camera module 100 can be bent upward and attached to the placement surface 21.

[0043] The supporting component includes a first support block 3 and a second support block 5. The first support block 3 is hinged to one side of the module pressing block 2, where the first support block 3 flips towards or away from the placement surface 13; the second support block 3 is hinged to the other side of the module pressing block 2, where the second support block 5 flips towards or away from the placement surface 21.

[0044] The bending component includes a bending block 4, a first extrusion block 8, a second extrusion block 7, a heating and laminating block 6, and a shaping and laminating block 9.

[0045] The bending block 4 is movably arranged on the module pressing block 2, where the bending block 4 moves along the direction of approaching or departing from the placement surface 21. When the first support block 3 is attached to the placement surface 21, the bending block 4 and the first support block 3 cooperate to perform the first bend on the FPC flexible cable 101 on the placement surface 21; after the first bend is completed, the first extrusion block 8 and the first support block 3 cooperate to perform the second bend on the FPC flexible cable 101 to be bent; after the second bend is completed, when the second support block 5 is attached to the placement surface 21, the second extrusion block 7 and the second support block 5 cooperate to perform the third bend on the FPC flexible cable 101 to be bent; after the third bend is completed, the heating and laminating block 6, the shaping and laminating block 9, and the second support block 5 cooperate to perform the fourth bend on the FPC flexible cable 101 to be bent.

[0046] In this application, through the cooperation of various components, the FPC flexible cable 101 to be bent can be folded into a predetermined shape, thus replacing the pure manual folding method, ensuring the folding accuracy and quality. At the same time, by using this application to fold the FPC flexible cable 101 to be bent, it can reduce the occurrence of situations such as spending a large amount of time to determine the folding position and folding mistakes during pure manual folding, thereby improving the folding efficiency and further improving the production efficiency.

[0047] In some embodiments, refer to Figure 2, at least one fixing post 12 is provided on the base 1. The fixing post 12 is located on the side of the card slot 11 and can be inserted into the hole positions on the side of the camera module 100, thereby positioning the camera module 100 so that it can be quickly placed in the corresponding position. At the same time, the fixing post 12 can play a certain fixing effect and enable the camera module 100 to be stably placed in the card slot 11.

[0048] Further, refer to Figure 2 , at least one sixth positioning post 13 is provided on the upper end surface of the base 1, and at least one positioning hole (not shown in the figure) is provided on the lower end surface of the module pressing block 2; the positioning holes and the sixth positioning posts 13 are in one-to-one correspondence, thereby realizing the detachable connection between the module pressing block 2 and the base 1.

[0049] Specifically in this embodiment, refer to Figure 13 , the FPC flexible cable 101 to be bent includes an inverted U-shaped structure, a horizontal straight-line structure, and a vertical straight-line structure; the FPC flexible cable 101 to be bent is bent four times to obtain the finished FPC flexible cable 102.

[0050] Correspondingly, please refer to Figure 3 and Figure 4 , in this embodiment, in order to make the placement of the FPC flexible cable 101 to be bent more rapid, a positioning component for positioning the FPC flexible cable 101 to be bent is provided on the placement surface 21. The design of this positioning component is based on the FPC flexible cable 101 to be bent. Specifically, the positioning component includes a positioning convex block 23 for positioning the inverted U-shaped structure and a positioning convex point 24 for positioning the vertical straight-line structure. The positioning convex block 23 is engaged with the inverted U-shaped structure to achieve positioning, and the vertical straight-line structure is positioned between the two positioning convex points 24. Of course, more positioning convex points 24 can also be provided as long as they are respectively on both sides of the vertical straight-line structure.

[0051] In order to fix the flexible printed circuit (FPC) cable 101 to be bent on the placement surface 21, a first air passage penetrating the module pressing block 2 is provided inside the module pressing block 2, and one end of the first air passage extends to the placement surface 21 to form a first suction port 22 on the placement surface; thus, after the FPC cable 101 to be bent is attached to the placement surface 21, the air extraction device is controlled to work through the first air passage, so that suction force is generated at the first suction port 22, thereby fixing the FPC cable 101 to be bent on the placement surface 21; the setting position and number of the first suction ports 22 on the placement surface 21 are determined according to the FPC cable 101 to be bent. That is to say, multiple first air passages can be provided inside the module pressing block 2. Of course, for more convenient air extraction, multiple first air passages can share a main air passage; specifically, the first suction ports 22 are provided at the positions on the placement surface 21 corresponding to the longitudinal linear structure. More specifically, the first suction ports 22 on the placement surface 21 for sucking the longitudinal linear structure are located between two positioning bumps 24, and the number thereof is two, and of course, it can also be more; the first suction ports 22 are also provided at the positions on the placement surface 21 corresponding to the inverted U-shaped structure. More specifically, the first suction ports 22 on the placement surface 21 for sucking the inverted U-shaped structure are arranged around the positioning bump 23, and the number thereof is four, and of course, it can also be more.

[0052] In order to be able to bend the horizontal linear structure of the FPC cable 101 to be bent by 90°, a receiving groove is machined on the upper end surface of the module pressing block 2, and a sliding groove penetrating the placement surface 21 is provided on the groove wall of the receiving groove. Among them, when the FPC cable 101 to be bent is attached to the placement surface 21, it is required that the bottom of the sliding groove, the upper end surface of the first support block 3, and the upper end surface of the second support block 5 are all located below the horizontal linear structure and above the inverted U-shaped structure; a sliding rod is provided in the receiving groove; the bending block 4 includes a pressing portion, the bending block 4 is arranged in the receiving groove, one end of the pressing portion is slidably connected with the sliding groove, and among them, the end of the pressing portion that is slidably connected with the sliding groove has a sixth side surface 41; the other end of the pressing portion is provided with a connecting portion; the connecting portion is slidably connected with the sliding rod; a spring 26 sleeved on the sliding rod is provided between the connecting portion and the groove wall of the receiving groove.

[0053] Furthermore, sliding rods are provided on both sides of the sliding groove in the receiving groove. Correspondingly, connecting portions are provided on both sides of the pressing portion, and the two connecting portions are respectively slidably connected with the two sliding rods, so as to make the installation and movement of the bending block 4 more stable.

[0054] In order to better place the horizontal linear structure, when the bending block 4 is not pushed to slide, the sixth side surface 41 is flush with the placement surface 21. At this time, in order to better fix the horizontal linear structure, a second air duct penetrating the bending block 4 is provided in the bending block 4. One end of the second air duct extends to the sixth side surface 41 to form a second suction port 42 on the sixth side surface 41. After the horizontal linear structure is attached to the sixth side surface 41, the pumping device operates to generate suction at the second suction port 42 through the second air duct, thereby fixing the horizontal linear structure on the sixth side surface 41.

[0055] See Figure 5 and Figure 6 , in order to be able to perform a 90° overpressure bending on the horizontal linear structure of the flexible FPC cable 101 to be bent, the first extrusion block 8 and the first support block 3 are used in cooperation to achieve this. The first support block 3 includes a first inclined surface 31, a first side surface 32, and a second side surface 33 for fitting with the placement surface 13. The first side surface 32 and the second side surface 33 are arranged opposite to each other; the upper end of the first inclined surface 31 is connected to the second side surface 33, and the lower end of the first inclined surface 31 is connected to the first side surface 32; a second positioning rod 34 is provided on the first inclined surface 31; the lower end surface of the first extrusion block 8 is a second inclined surface 81 matching the first inclined surface 31; the second inclined surface 81 is provided with a second positioning socket 82 for plugging and matching with the second positioning rod 34; specifically, the first support block 3 is flipped so that the first support block 3 is attached to and fixed on the placement surface 21, then the horizontal linear structure is manually moved to the first inclined surface 31, and then the first extrusion block 8 is manually or electrically controlled. The connection between the first extrusion block 8 and the first support block 3 is completed by the plugging of the second positioning rod 34 and the second positioning socket 82. When the first extrusion block 8 and the first support block 3 are completely attached, the horizontal linear structure is clamped between the second inclined surface 81 and the first inclined surface 31, and the second inclined surface 81 and the first inclined surface 31 cooperate to perform a 90° overpressure bending operation.

[0056] Furthermore, the number of the second positioning rods 34 is two. Correspondingly, the number of the second positioning sockets 82 is also two, so that the connection between the first extrusion block 8 and the first support block 3 is more stable. Of course, the number of the second positioning rods 34 can be more, depending on the specific situation.

[0057] Further, in order to make the first support block 3 fit more closely to the placement surface 21, an avoidance hole 36 for avoiding the positioning bump 24 and an avoidance notch 35 for avoiding the positioning projection 23 are provided on the first support block 3. A first positioning rod 37 and a first magnet 38 are provided on the second side surface 33. A first positioning socket 27 for inserting and mating with the first positioning rod 37 and a second magnet 25 for adsorbing and mating with the first magnet 38 are provided on the placement surface 21. In this way, the first support block 3 is flipped so that the first support block 3 is attached to and fixed to the placement surface 21, that is, the first positioning rod 37 and the first positioning socket 27 are inserted and mated, and the second magnet 25 and the first magnet 38 are fixed. In order for the first positioning rod 37 and the first positioning socket 27 to be inserted and mated after the first support block 3 is flipped, the first positioning socket 27 is an oval hole.

[0058] See Figure 7 , Figure 8 and Figure 11 , in order to bend an obtuse angle on the horizontal linear structure of the to-be-bent FPC flexible cable 101, the second support block 5 and the second extrusion block 7 are used in cooperation to achieve this. The upper end surface of the second support block 5 includes a first plane 51, a third inclined surface 52, and a second plane 53 that are sequentially connected. The upper end of the third inclined surface 52 is connected to the first plane 51, and the lower end of the third inclined surface 52 is connected to the second plane 53. A third positioning rod 54 is provided on the first plane 51. The lower end surface of the second extrusion block 7 includes a fourth inclined surface 71 that is inclined and mated with the third inclined surface 52, a third plane 72 that is mated with the first plane 51, and a fourth plane 73 that is mated with the second plane 53. A third positioning socket 74 for inserting and mating with the third positioning rod 54 is provided on the third plane 72. The second support block 5 is flipped so that the second support block 5 is attached to and fixed to the placement surface 21. It is required to manually move the vertical linear structure out from between the second support block 5 and the placement surface 21, then manually move part of the horizontal linear structure onto the first plane 51, and then manually or electrically control the second extrusion block 7. The connection between the second extrusion block 7 and the second support block 5 is completed by inserting the third positioning socket 74 and the third positioning rod 54. When the second extrusion block 7 and the second support block 5 are completely attached, part of the horizontal linear structure is clamped between the upper end surface of the second support block 5 and the lower end surface of the second extrusion block 7, and an obtuse angle is obtained by the cooperation of the first plane 51 and the third plane 72, the cooperation of the second plane 53 and the fourth plane 73, and the cooperation of the third inclined surface 52 and the fourth inclined surface 71.

[0059] Further, the number of the third positioning rods 54 is two. Correspondingly, the number of the third positioning sockets 74 is also two, so as to make the connection between the second support block 5 and the second extrusion block 7 more stable. Of course, the number of the third positioning rods 54 can be more, depending on the specific situation.

[0060] Further, in order to make the connection between the second support block 5 and the second extrusion block 7 more stable, a seventh magnetic block 513 is provided on the first plane 51.

[0061] Further, in order to make the second support block 5 fit more closely to the placement surface 21, the second support block 5 includes a fourth side surface 56 and a third side surface 55 for fitting with the placement surface 21. The third side surface 55 and the fourth side surface 56 are oppositely arranged. The third side surface 55 is provided with a fourth positioning rod 57 that is inserted and matched with the first positioning socket 27 and a third magnetic block 58 that is adsorbed and matched with the second magnetic block 25. In this way, the second support block 5 is flipped so that the second support block 5 is attached to and fixed to the placement surface 21, that is, the fourth positioning rod 57 and the first positioning socket 27 are inserted and matched, and the third magnetic block 58 and the second magnetic block 25 are fixed.

[0062] See Figure 9 、 Figure 10 and Figure 12, in order to bend the M-shaped structure on the finished FPC flexible cable 102 from the horizontal linear structure of the FPC flexible cable 101 to be bent, the cooperation of the heating pressing block 6, the shaping pressing block 9 and the second support block 5 is used to achieve this. The heating pressing block 6 includes a fifth side surface 61 for fitting with the fourth side surface 56. A shaping convex block is provided on the fifth side surface 61. The shaping convex block includes an M-shaped block 62 and a horizontal block 63 for fitting with the first plane 51 connected in sequence. The upper end surface of the horizontal block 63 is parallel to the upper end surface of the M-shaped block 62, and the angle between the lower end surface of the horizontal block 63 and the lower end surface of the M-shaped block 62 is an obtuse angle. A shaping groove 91 that is engaged with the shaping convex block is provided on the shaping pressing block 9. A fifth positioning socket for inserting and cooperating with the third positioning rod 54 is provided on the lower end surface of the shaping pressing block 9. Flip the second support block 5 so that the second support block 5 is only fixed to the inverted U-shaped structure with the placement surface 21. Then manually move part of the horizontal linear structure to the first plane 51. Then manually or electrically control the heating pressing block 6 so that the heating pressing block 6 fits with the fourth side surface 56. That is, part of the horizontal linear structure is limited between the lower end surface of the shaping convex block and the upper end surface of the second support block 5, that is, between the first plane 51 and the horizontal block 63 and between the lower end surface of the M-shaped block 62 and the third inclined surface 52. And the first plane 51 and the horizontal block 63 are used to cooperate to fix part of the horizontal linear structure. Then manually move the remaining part of the horizontal linear structure so that the remaining part of the horizontal linear structure bypasses the M-shaped block 62 and is placed on the upper end surface of the shaping convex block. Then manually or electrically control the shaping pressing block 9, and complete the connection between the shaping pressing block 9 and the second support block 5 by inserting the fifth positioning socket and the third positioning rod 54, and complete the fixation between the shaping pressing block 9 and the second support block 5 through the seventh magnetic block 513. When the shaping pressing block 9 and the second support block 5 are completely fitted, the shaping groove 91 is engaged with the shaping convex block, that is, the horizontal linear structure is limited between the shaping convex block, the shaping groove 91 and the upper end surface of the second support block 5. Finally, heat the shaping pressing block 9 or the heating pressing block 6 so that the shaping convex block, the shaping groove 91 and the upper end surface of the second support block 5 cooperate to bend out the M-shaped structure.

[0063] Further, in order to stably and quickly connect the second support block 5 and the heating and laminating block 6, a fifth positioning rod 59 and a fourth magnet 510 are provided on the fourth side surface 56, and a fourth positioning jack 64 that is inserted and cooperated with the fifth positioning rod 59 and a fifth magnet 65 that is adsorbed and cooperated with the fourth magnet 510 are provided on the fifth side surface 61. In order to better fix the forming convex block, both the fourth positioning jack 64 and the fifth magnet 65 are located directly below the forming convex block. In this way, the second support block 5 and the heating and laminating block 6 are attached and fixed, that is, they are inserted and cooperated through the fifth positioning rod 59 and the fourth positioning jack 64, and adsorbed and fixed by the fifth magnet 65 and the fourth magnet 510. Of course, in order to make the connection between the second support block 5 and the heating and laminating block 6 more stable, the number of the fifth positioning rods 59 is two, and correspondingly, the number of the fourth positioning jacks 64 is also two.

[0064] Further, in order to make the connection between the second support block 5 and the heating and laminating block 6 more stable, a support rod 511 for supporting the heating and laminating block 6 is provided on the fourth side surface 56, and a sixth magnet 512 for adsorbing the heating and laminating block 6 is provided on the fourth side surface 56.

[0065] Further, in order to make the operation of the shaping and laminating block 9 more convenient, the shaping and laminating block 9 is hingedly connected to the second support block 5, and the shaping and laminating block 9 is flipped towards or away from the upper end surface of the second support block 5. During operation, the shaping and laminating block 9 can be manually flipped to perform the bending work. In order to enable the fifth positioning jack and the third positioning rod 54 to be inserted and cooperated after the shaping and laminating block 9 is flipped, the fifth positioning jack is an oval hole.

[0066] In some embodiments, in order to facilitate manual operation, operating rods 10 are provided on the bending block 4, the first pressing block 8, the second pressing block 7, the heating and laminating block 6, and the shaping and laminating block 9.

[0067] The specific working process of this application is as follows:

[0068] 1. Place the camera module 100 into the card slot 11 of the base 1, and position the camera module 100 through the fixing column 12. Among them, the upper end surface of the camera module 100 is attached with the FPC flexible cable 101 to be bent, and at this time, the FPC flexible cable 101 to be bent is placed horizontally. (See Figure 12 ) The FPC flexible cable 101 to be bent includes an inverted U-shaped structure, a horizontal linear structure, and a vertical linear structure.

[0069] 2. Install the module pressing block 2 on the base 1, and insert and connect the module pressing block 2 through the sixth positioning column 13 to further fix the camera module 100 and make it stably placed.

[0070] 3. After fixing the camera module 100, the suction device operates to generate suction forces at both the first suction port 22 and the second suction port 42. Then, manually bend the flexible printed circuit (FPC) cable 101 to be bent on the camera module 100 upward. Due to the suction force, the inverted U-shaped structure and the vertical linear structure are closely attached to the placement surface 21, and the horizontal linear structure is also closely attached to the sixth side surface 41. Positioning is achieved through the engagement of the positioning bumps 24 with the vertical linear structure and the engagement of the positioning protrusions 23 with the inverted U-shaped structure (see Figure 4 ).

[0071] 4. Rotate the first support block 3 so that the first support block 3 moves towards the module pressing block 2. Continue to rotate the first support block 3 until the first support block 3 is closely attached to the placement surface 21. The first support block 3 is magnetically fixed to the module pressing block 2, and both the inverted U-shaped structure and the vertical linear structure are clamped between the side walls of the first support block 3 and the module pressing block 2 (see Figure 6 ).

[0072] 5. Push the bending block 4 so that the bending block 4 moves towards the FPC cable 101 to be bent. At the same time, the spring 26 is compressed. Continue to push the bending block 4 until the edge of the bending block 4 and the first support block 3 cooperate to bend the horizontal linear structure towards the first inclined surface 31, and at this time, the first bending, that is, a 90° bending, is completed.

[0073] 6. Release the bending block 4, and the bending block 4 resets under the action of the spring 26.

[0074] 7. Use the first extrusion block 8, insert the first extrusion block 8 onto the first support block 3, and place the horizontal linear structure between the first inclined surface 31 and the second inclined surface 81. Then, apply pressure to the first extrusion block 8 to shape the FPC cable 101 to be bent, so that an angle α is formed between the horizontal linear structure and the vertical linear structure and between the horizontal linear structure and the inverted U-shaped structure. At this time, the second bending, that is, a 90° overpressure bending, is completed.

[0075] 8. Remove the first extrusion block 8 and rotate the first support block 3 so that the first support block 3 moves away from the module pressing block 2.

[0076] 9. Rotate the second support block 5 so that the second support block 5 moves towards the module pressing block 2. Continue to rotate the second support block 5 until the second support block 5 is closely attached to the placement surface 21. Manual arrangement is required as follows: Take out the vertical linear structure from between the second support block 5 and the module pressing block 2, and make the end of the horizontal linear structure close to the inverted U-shaped structure fit onto the first plane 51 of the second support block 5.

[0077] 10. Use the second extrusion block 7. Insert the second extrusion block 7 onto the second support block 5. Part of the horizontal linear structure is clamped between the upper end face of the second support block 5 and the lower end face of the second extrusion block 7. Then, use the third inclined surface 52 provided on the upper end face of the second support block 5 and the fourth inclined surface 71 provided on the lower end face of the second extrusion block 7 to bend the horizontal linear structure, such that one end of the horizontal linear structure far from the inverted U-shaped structure is inclined downward relative to the other end. That is to say, after the horizontal linear structure is bent, it is divided into a horizontal section and an inclined section, completing the third bending, namely, bending an obtuse angle on the horizontal linear structure (see 11).

[0078] 11. Remove the second extrusion block 7. Use the heating and pressing block 6. Set the heating and pressing block 6 on the second support block 5, such that one end of the horizontal linear structure close to the inverted U-shaped structure is limited between the upper end face of the second support block 5 and the forming convex block. That is to say, the horizontal section of the horizontal linear structure is clamped between the first plane 51 of the second support block 5 and the lower end face of the horizontal block 63, and a part of the inclined section of the horizontal linear structure is located between the lower end face of the M-shaped block 62 and the third inclined surface 52. Among them, the following manual arrangement is required: bypass the remaining part of the inclined section of the horizontal linear structure around the V-shaped side surface of the M-shaped block 62 and place it on the upper end face of the forming convex block (see Figure 10 ).

[0079] 12. Rotate the shaping and pressing block 9, such that the shaping and pressing block 9 flips onto the forming convex block. Continue to rotate the shaping and pressing block 9 until the shaping and pressing block 9 fits with the first plane 51 of the second support block 5. Among them, the forming convex block is located between the shaping groove 91 and the second support block 5. In other words, the horizontal linear structure is arranged in the gap formed by the forming convex block, the shaping groove 91 and the second support block 5. Then, apply pressure at the shaping and pressing block 9 to extrude the horizontal linear structure to shape it. At the same time, the heating and pressing block 6 is electrified and heated to further ensure the shaping effect. Finally, an M-shaped structure will be formed on the finished FPC flexible cable 102 (see Figure 12 ).

[0080] 13. After the folding steps of the FPC flexible cable 101 to be bent are completed, subsequently, the shaping and pressing block 9, the heating and pressing block 6, the second support block 5 and the module pressing block 2 can be loosened in sequence, and then the finished FPC flexible cable 102 can be obtained (see Figure 14 ).

[0081] The finished FPC flexible cable 102 produced in this way can ensure the folding accuracy of the product to the greatest extent, ensure the folding quality, and the components cooperate with each other. Compared with the traditional pure manual folding method, the folding in this application is simple and convenient, with high work efficiency. At the same time, the components can be disassembled and assembled conveniently, which can further improve the work efficiency.

[0082] As long as it does not violate the idea of the present invention, any combination of various different embodiments of the present invention shall be regarded as the content disclosed by the present invention; within the scope of the technical concept of the present invention, various simple modifications of the technical solution and any combination of different embodiments that do not violate the idea of the present invention shall be within the protection scope of the present invention.
