DETAILED DESCRIPTION

[0029] At present, the pre-stressing and bending process of FPC cables mainly relies on manual cylinder squeezing. Although this method can realize the pre-stressing and bending operation of FPC cables, there is an unstable pressure during the pre-stressing and bending process, which not only leads to poor consistency of the shape and angle of the FPC cables after bending, and the quality cannot be guaranteed, but also, since the FPC cables are relatively soft, it is easy to cause damage or even breakage of the FPC cables. In addition, the efficiency of pre-stressing and bending FPC cables manually is low and cannot meet production needs.

[0030] Therefore, the purpose of the present invention is to provide an FPC pre-stressing and bending device to at least solve the technical problem that the pre-stressing and bending of FPC cables by manual method results in poor consistency of shape and angle after bending.

[0031] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0032] Figure 1 This is one of the structural schematic diagrams of the FPC cable pre-pressing and bending device provided in this embodiment. Figure 1 As shown, this embodiment provides an FPC cable pre-stressing and bending device, including a supporting assembly 100, a wire pressing assembly 200 and a bending assembly 300, wherein the supporting assembly 100 includes a support platform 110 for supporting the FPC cable; the wire pressing assembly 200 includes a fixed knife 210 and a wire pressing drive mechanism 220 for driving the fixed knife 210 to approach or move away from the FPC cable.

[0033] Figure 2 for Figure 1 A magnified view of the local structure at point A in the middle. Figure 3 This is the second structural diagram of the FPC cable pre-pressing and bending device provided in this embodiment. Please continue to refer to Figure 1 , and combined with Figure 2 and Figure 3 The fixed knife 210 includes a pressing surface 211 facing the FPC cable and an inclined surface 212 set at an angle to the pressing surface 211, and the pressing surface 211 and the inclined surface 212 intersect to form a forming angle block 213; the bending assembly 300 includes a moving knife 310 and a bending drive mechanism 320 for driving the moving knife 310 to approach or move away from the FPC cable. The moving knife 310 and the fixed knife 210 are respectively arranged on the upper and lower sides of the FPC cable, and the moving knife 310 is provided with a forming notch 311 that is adapted to the shape of the forming angle block 213.

[0034] When the FPC cable needs to be pre-pressed and bent, the FPC cable can be placed on the support platform 110. At this time, one of the fixed knife 210 and the movable knife 310 is located above the FPC cable, and the other of the fixed knife 210 and the movable knife 310 is located below the FPC cable. Afterwards, the pressing drive mechanism 220 is actuated to drive the fixed knife 210 to approach the FPC cable, and the FPC cable is pressed by the pressing surface 211 of the fixed knife 210. Then, the bending drive mechanism 320 is actuated to drive the movable knife 310 to approach the FPC cable. In the process of the movable knife 310 gradually approaching the FPC cable, the forming notch 311 provided on the movable knife 310 will first contact the FPC cable, and further drive the FPC cable to be bent in the direction of the forming angle block 213. When the forming notch 311 of the movable knife 310 is engaged with the forming angle block 213 of the fixed knife 210, the bending operation of the FPC cable is completed. After the bending operation is completed, the fixed knife 210 is driven away from the FPC cable by the pressing drive mechanism 220, while the movable knife 310 is driven away from the FPC cable by the bending drive mechanism 320, thereby obtaining a bent FPC cable.

[0035] The FPC cable pre-pressing and bending device realizes automatic bending of the FPC cable by using the cooperation of the movable knife 310 and the fixed knife 210, so that the shape and angle of the FPC cable after bending are determined by the shapes and angles of the movable knife 310 and the fixed knife 210, and the pressure is stable, thereby ensuring the consistency of the shape and angle. Moreover, this method of pre-pressing and bending the FPC cable using the FPC cable pre-pressing and bending device has high production efficiency and can meet production needs.

[0036] Figure 4 This is one of the structural schematic diagrams of the bending assembly 300 of the FPC cable pre-pressing and bending device provided in this embodiment; Figure 5 This is the second structural diagram of the bending assembly 300 of the FPC cable pre-pressing and bending device provided in this embodiment. Figure 1 , and combined with Figure 4 and Figure 5 In this embodiment, the bending drive mechanism 320 may include a linear drive member 321, and the bending assembly 300 also includes a connecting frame 330 and a buffer structure 340, wherein the connecting frame 330 includes a first plate 331 and a second plate 332 connected at an angle, the first plate 331 is fixedly connected to the output end of the linear drive member 321, and the movable knife 310 is slidably installed on the first plate 331, and the sliding direction of the movable knife 310 is consistent with the power output direction of the linear drive member 321; the buffer structure 340 is arranged between the movable knife 310 and the second plate 332.

[0037] When the FPC cable is pre-bent, the linear drive member 321 is actuated to drive the movable knife 310 to move in the direction of the FPC cable, so that the forming notch 311 of the movable knife 310 is engaged with the forming angle block 213 of the fixed knife 210, thereby bending the FPC cable between the movable knife 310 and the fixed knife 210. After the forming notch 311 of the movable knife 310 is fully engaged with the forming angle block 213 of the fixed knife 210, as the movable knife 310 continues to move, the pressure between the movable knife 310 and the fixed knife 210 will be buffered by the buffer structure 340.

[0038] The buffer structure 340 can buffer the pressure between the movable knife 310 and the fixed knife 210 to prevent the FPC cable from being damaged by excessive pressure between the movable knife 310 and the fixed knife 210, thereby protecting the FPC cable to a certain extent.

[0039] In this embodiment, the first plate 331 and the second plate 332 are connected at approximately right angles; the linear drive member 321 is a servo electric cylinder; the power output direction of the linear drive member 321 is obliquely upward, that is, the movable knife 310 moves obliquely upward to engage with the fixed knife 210.

[0040] Please continue to refer to Figure 1 , Figure 4 and Figure 5 In this embodiment, the bending assembly 300 may further include a pressure sensor 350 . Specifically, the pressure sensor 350 is disposed between the buffer structure 340 and the second plate 332 . The pressure sensor 350 is configured to sense the pressure of the movable knife 310 transmitted through the buffer structure 340 .

[0041] In the process of the linear drive member 321 driving the movable knife 310 to move in the direction of the FPC cable to bend the FPC cable, after the forming notch 311 of the movable knife 310 is fully engaged with the forming angle block 213 of the fixed knife 210, as the movable knife 310 continues to move, the movable knife 310 will slide downward on the first plate 331 of the connecting frame 330; when the movable knife 310 slides downward for a certain distance, the pressure sensor 350 will be triggered, and as the movable knife 310 continues to slide downward, the buffer structure 3 40 will buffer the pressure between the movable knife 310 and the fixed knife 210 to prevent the FPC cable from being damaged by excessive pressure. In this process, the pressure sensor 350 senses the pressure of the movable knife 310 transmitted by the buffer structure 340, that is, the pressure of the FPC cable is fed back in real time through the pressure sensor 350 to control the extension action of the linear drive member 321 to prevent the linear drive member 321 from being damaged by excessive pressure on the FPC cable due to excessive movement.

[0042] The arrangement of the pressure sensor 350 can achieve real-time sensing of the pressure on the FPC cable, thereby accurately controlling the extension of the linear drive member 321, achieving automatic pressure adjustment, and effectively improving the situation of excessive or insufficient pre-pressure in the manual method, improving the manufacturing quality, and ensuring the yield rate. In addition, the arrangement can also avoid damage or breakage caused by excessive pressure on the FPC cable, and play a certain protective role on the FPC cable.

[0043] Please continue to refer to Figure 4 and Figure 5 In this embodiment, the first plate 331 is installed with a slide rail 360, and the movable knife 310 is fixedly connected with a first slider 370, wherein the slide rail 360 extends along the power output direction of the linear drive member 321, and the first slider 370 slides with the slide rail 360.

[0044] By providing a slide rail 360 on the first plate 331 and a first slider 370 slidably matched with the slide rail 360 on the movable knife 310, not only the sliding connection between the movable knife 310 and the first plate 331 is achieved, but also the smoothness of the sliding of the movable knife 310 relative to the first plate 331 is ensured.

[0045] Please continue to refer to Figure 4 and Figure 5 In this embodiment, the buffer structure 340 may include a second slider 341, a fixed block 342, a guide rod 343, a coil spring 344 and a mounting block 345, wherein the second slider 341 is slidably matched with the slide rail 360, and the second slider 341 is close to the second plate 332, that is, the first slider 370 is located above the second slider 341; the fixed block 342 is fixedly connected to the second slider 341, the guide rod 343 is fixedly connected to the fixed block 342, the mounting block 345 is fixedly connected to the movable knife 310, and the mounting block 345 is provided with a guide hole for the guide rod 343 to pass through; the coil spring 344 is sleeved on the rod section of the guide rod 343 located between the fixed block 342 and the mounting block 345.

[0046] When the linear drive member 321 drives the movable knife 310 to extend excessively so that the movable knife 310 is subjected to pressure from the fixed knife 210, the movable knife 310 will slide downward on the first plate 331 through the first slider 370; in the process of the movable knife 310 sliding downward, the first slider 370 will drive the mounting block 345 fixed thereon to slide downward, during which the movement of the mounting block 345 is transmitted to the second slider 341 through the coil spring 344 and the fixed block 342, thereby realizing the synchronous movement of the movable knife 310, the first slider 370, the mounting block 345, the guide rod 343, the coil spring 344, the fixed block 342 and the second slider 341, during which the coil spring 344 does not generate compression potential energy; as the movable knife 310 slides downward, the first slider 370 will drive the mounting block 345 fixed thereon to slide downward, during which the movement of the mounting block 345 is transmitted to the second slider 341 through the coil spring 344 and the fixed block 342, thereby realizing the synchronous movement of the movable knife 310, the first slider 370, the mounting block 345, the guide rod 343, the coil spring 344, the fixed block 342 and the second slider 341, during which the coil spring 344 does not generate compression potential energy; 310 continues to slide downward, and the fixed block 342 will contact the sensing end of the pressure sensor 350 to trigger the pressure sensor 350 to perform pressure detection, thereby accurately controlling the extension length of the linear drive member 321 to prevent the FPC cable from being crushed. In this process, when the extension length of the linear drive member 321 is not adjusted in time, that is, when the fixed block 342 has contacted the pressure sensor 350 and the movable knife 310 still drives the fixed block 342 to move downward, the movable knife 310 will compress the coil spring 344 through the mounting block 345, and use the elastic potential energy generated by the compression of the coil spring 344 to buffer the pressure on the movable knife 310, so as to achieve the purpose of protecting the FPC cable.

[0047] This arrangement of the buffer structure 340 can not only effectively buffer the pressure exerted on the movable knife 310, but also has a simple structure and is easy to arrange.

[0048] Please continue to refer to Figure 4 and Figure 5 In this embodiment, the buffer structure 340 may further include an adjustment plate 346. Specifically, the adjustment plate 346 is provided with a clearance hole 3461 and a strip hole 3462, wherein one end of the adjustment plate 346 is fixedly connected to the first slider 370, and the mounting block 345 is passed through the clearance hole 3461; the second slider 341 is provided with a connecting screw hole (not shown in the figure) opposite to the strip hole 3462, and the connecting screw hole is adapted to the strip hole 3462 opened in the adjustment plate 346, that is, the connecting screw hole opened in the second slider 341 is used in conjunction with the strip hole 3462 opened in the adjustment plate 346.

[0049] When the buffer structure 340 is in use, the preload force of the coil spring 344 can be adjusted in advance to ensure that the coil spring 344 has different support stiffnesses, so that the buffer structure 340 has different support capabilities. Specifically, when the supporting stiffness of the coil spring 344 needs to be increased, the second slider 341 can be moved upward so that the connecting screw hole is opposite to the upper section of the strip hole 3462, and the connecting bolt is passed through the strip hole 3462 and screwed into the connecting screw hole to fix the adjustment plate 346 at the current position. At this time, the distance between the fixing block 342 and the mounting block 345 is reduced, the coil spring 344 is compressed, and the supporting stiffness of the coil spring 344 is increased; and when the supporting stiffness of the coil spring 344 needs to be reduced, the second slider 341 is moved downward so that the connecting screw hole is opposite to the lower section of the strip hole 3462, and the connecting bolt is passed through the strip hole 3462 and screwed into the connecting screw hole to fix the adjustment plate 346 at the current position. At this time, the distance between the fixing block 342 and the mounting block 345 is reduced, and the coil spring 344 is stretched under the action of the elastic potential energy originally stored, so as to achieve the purpose of reducing the supporting stiffness of the coil spring 344.

[0050] By providing the adjustment plate 346 , the support stiffness of the coil spring 344 can be adjusted, so that before the bending assembly 300 bends the FPC cable, the buffer structure 340 can have different buffering properties to adapt to different bending conditions.

[0051] Please continue to refer to Figure 4 and Figure 5 In this embodiment, a limiting plate 380 is fixedly disposed on the first plate 331, and the limiting plate 380 is configured to limit the maximum travel of the first slider 370 moving in the direction of the FPC cable.

[0052] The setting of the above-mentioned limiting plate 380 can limit the maximum travel of the first slider 370 moving in the direction of the FPC cable, thereby preventing the first slider 370 from escaping from the slide rail 360 .

[0053] Please continue to refer to Figure 1 and Figure 3 In this embodiment, the bending drive mechanism 320 may further include a bending slide 322, wherein the linear drive member 321 is installed at the output end of the bending slide 322, and the bending slide 322 is configured to drive the linear drive member 321 to move in the X direction and the Y direction.

[0054] Before using the FPC cable pre-compression bending device, the bending slide 322 can be used to adjust the position of the linear drive member 321 in the X direction and the Y direction, that is, to achieve the purpose of adjusting the position of the movable knife 310 in the X direction and the Y direction. It can be seen that the setting of the bending slide 322 realizes the adjustment of the position of the movable knife 310 in the X direction and the Y direction, thereby ensuring the reliability of the movable knife 310 engaging with the fixed knife 210 after being extended.

[0055] Please continue to refer to Figure 1 and Figure 3 In this embodiment, the bending drive mechanism 320 may further include a first mounting seat 323 , and the linear drive member 321 is mounted on the output end of the bending slide 322 through the first mounting seat 323 .

[0056] Please continue to refer to Figure 1 and Figure 3 In this embodiment, the supporting assembly 100 may further include a supporting driving mechanism 120. Specifically, the support platform 110 is installed at the output end of the supporting driving mechanism 120, and the supporting driving mechanism 120 is configured to drive the support platform 110 to move in the X direction, the Y direction and the Z direction; the wire pressing driving mechanism 220 is configured to drive the fixed knife 210 to move in the X direction, the Y direction and the Z direction.

[0057] Before using the FPC cable pre-stressing and bending device, the support driving mechanism 120 can be used to adjust the position of the support platform 110 in the X direction, the Y direction and the Z direction to ensure the bearing accuracy of the FPC cable; and the position of the fixed knife 210 in the X direction and the Y direction can be adjusted by the wire pressing driving mechanism 220, so that the position of the fixed knife 210 in the X direction and the Y direction is consistent with the support platform 110, that is, the fixed knife 210 is located above the support platform 110, so that when the wire pressing driving mechanism 220 drives the fixed knife 210 to move downward, the FPC cable is pressed against the support platform 110.

[0058] Please continue to refer to Figure 1 and Figure 3 In this embodiment, the supporting drive mechanism 120 may include a supporting cylinder 121, a supporting slide 122, and a second mounting seat 123, wherein the second mounting seat 123 is fixedly connected to the output end of the supporting slide 122, and the supporting cylinder 121 is mounted on the second mounting seat 123. When the supporting slide 122 moves, the second mounting seat 123 and the supporting cylinder 121 mounted on the second mounting seat 123 are driven to move along the X direction and the Y direction to ensure the position of the support platform 110 in the X direction and the Y direction; when the support platform 110 moves to the required X direction and Y direction position, the supporting slide 122 stops moving, and the supporting cylinder 121 extends upward to support the FPC cable.

[0059] Please continue to refer to Figure 1 and Figure 3In this embodiment, the wire pressing drive mechanism 220 may include a translation cylinder 221, a lifting cylinder 222, a wire pressing slide 223 and a third mounting seat 224. Specifically, the third mounting seat 224 is installed at the output end of the wire pressing slide 223, the lifting cylinder 222 is installed at the third mounting seat 224, and the translation cylinder 221 is installed at the output end of the lifting cylinder 222. The translation cylinder 221 is used to drive the fixed knife 210 to approach or move away from the movable knife 310 in the horizontal plane.

[0060] Before using the wire pressing assembly 200, the position of the third mounting seat 224 in the X direction and the Y direction can be adjusted by using the wire pressing slide 223. At this time, the lifting cylinder 222, the translation cylinder 221 and the fixed knife 210 will move synchronously in the X direction and the Y direction to ensure the position of the fixed knife 210 in the X direction and the Y direction; when the fixed knife 210 moves to the required position in the X direction and the Y direction, the wire pressing slide 223 stops moving, and the lifting cylinder 222 extends downward, so that the pressing surface 211 of the fixed knife 210 presses the FPC cable on the support platform 110. After the bending operation of the FPC cable is completed, the translation cylinder 221 will move to drive the fixed knife 210 to move in a direction away from the movable knife 310, so that the fixed knife 210 withdraws from the bending part of the FPC cable to form a gap; then, the upward movement of the lifting cylinder 222 is used to make the fixed knife 210 move upward away from the FPC cable to release the pressing effect on the FPC cable.

[0061] The arrangement of the above-mentioned translation cylinder 221 can realize the retraction of the fixed knife 210, and avoid the fixed knife 210 directly moving upward and retracting after bending to destroy the bending angle or even damage the FPC cable, further ensuring the bending quality of the FPC cable. Before the fixed knife 210 is used for the next pressing, it is only necessary to make the translation cylinder 221 drive the fixed knife 210 to translate and reset.

[0062] It should be noted that, in the present embodiment, the supporting slide 122, the pressing slide 223 and the bending slide 322 can be manual slides or electric slides for outputting movements along the X-direction and the Y-direction. The specific structure and working principle can be obtained by those skilled in the art based on the prior art. This embodiment does not make any improvements on this, so it will not be described in detail.

[0063] In this embodiment, the fixed knife 210 is detachably disposed at the output end of the wire pressing driving mechanism 220 . Specifically, the fixed knife 210 is detachably connected to the output end of the translation cylinder 221 .

[0064] The above-mentioned setting of the fixed knife 210, on the one hand, is convenient for disassembling and maintaining the fixed knife 210 after being used for a period of time, thereby improving the convenience of maintaining the fixed knife 210. On the other hand, it is also convenient for adaptively adjusting the specifications of the fixed knife 210 after the size of the FPC cable is changed, without the need to replace the FPC cable pre-stressing and bending device as a whole, thereby improving the versatility of the FPC cable pre-stressing and bending device.

[0065] In this embodiment, the movable knife 310 is detachably disposed at the output end of the bending drive mechanism 320 . Specifically, the movable knife 310 is detachably connected to the first sliding block 370 .

[0066] The above-mentioned setting of the movable knife 310, on the one hand, is convenient for disassembly and maintenance of the movable knife 310 after being used for a period of time, thereby improving the convenience of maintenance of the movable knife 310; on the other hand, it is also convenient for adaptively adjusting the specifications of the movable knife 310 after the specifications of the fixed knife 210 are adjusted, without the need to replace the FPC cable pre-stressing and bending device as a whole, thereby further improving the versatility of the FPC cable pre-stressing and bending device.

[0067] Please continue to refer to Figure 1 In this embodiment, the number of the supporting platforms 110 is two, and the two supporting platforms 110 are arranged at intervals along the X direction. The number of the fixed knives 210 is the same as the number of the supporting platforms 110, which is also two. The two fixed knives 210 are respectively arranged in a one-to-one correspondence with the two supporting platforms 110; the number of the bending assemblies 300 is the same as the number of the fixed knives 210, which is two groups, and the two groups of bending assemblies 300 are respectively arranged in a one-to-one correspondence with the two fixed knives 210.

[0068] This arrangement enables simultaneous bending of two FPC cables, further improving the bending efficiency.

[0069] Please continue to refer to Figure 1 Specifically, the two supporting platforms 110 are installed at the output end of the supporting cylinder 121, and are driven by the supporting cylinder 121 to rise and fall synchronously; the two fixed knives 210 are installed at the output end of the translation cylinder 221, and are driven by the translation cylinder 221 to translate synchronously.

[0070] In other embodiments, the number of the support platforms 110 may be other numbers. In this case, the number and position of the fixed knives 210 and the bending components 300 can be adjusted synchronously.
