Description

[0001] The present invention belongs to the technical field of flexible printed circuit (FPC) perforation, and particularly relates to an assembled FPC perforation structure. Background Art

[0002] In current display modules, in order to improve the appearance of the product (meet the requirements of narrow bezels) and the dust, water, and smoke-proof performance of the product, the FPC on the backlight module needs to be assembled by perforation, which requires the introduction of a jig for perforating and assembling the FPC. There are currently two methods for perforating the FPC. One is that manual installation of the FPC is required, and at the same time, manual work for a long time results in low efficiency. The other is that the TFT module is adsorbed by a mechanical gripper to drive the TFT module to correspond to the backlight panel 101 and at the same time make the FPC 103 correspond to the interface. When descending, the TFT module is placed on the backlight panel, and at the same time, the FPC is inserted into the interface. In this case, the FPC is likely to be misaligned with the interface. If there is a deviation, it will be inserted obliquely. At the same time, the material of the FPC is relatively soft, and it may be bent and folded during insertion and blocked in the interface, affecting the efficiency. Summary of the Invention

The assembly FPC cable perforation structure guides the descending FPC cable through a U-shaped frame that is wider at the top and narrower at the bottom. Before the FPC cable comes into initial contact with the U-shaped frame, a force is applied to the side of the U-shaped frame through an adjustment component, causing the side of the U-shaped frame to bend outward synchronously to form an outward-expanded guiding channel to widen the cable channel. By reducing the contact area, the resistance during the feeding process of the end of the FPC cable is reduced, preventing the FPC cable from folding during descent, thus achieving accurate and complete access to the bottom opening of the U-shaped frame.

The assembly FPC cable perforation structure eliminates wrinkles in the FPC cable by using its own gravity after clamping the FPC cable, while avoiding damage to the material caused by hard pulling.

[0019] Embodiment 1: Refer to Figure 1 - Figure 10 , Figure 16 , an assembled flexible printed circuit (FPC) cable perforation structure, including a base 1, a TFT module 102, a YZ-axis moving and picking mechanism 2 for horizontally moving and vertically moving the TFT module 102, and a backlight panel 101 placed in the base 1; During use, the backlight panel 101 is placed in the base 1. The TFT module 102 is adsorbed by the suction cup at the output end of the YZ-axis moving and picking mechanism 2 and driven to move to the top of the base 1, and then pushed down to insert the FPC cable 103 of the TFT module 102 into the interface 104 opened on the base 1; In the prior art, there is a certain space between the FPC cable 103 and the interface 104, and there may be a certain deviation when pushing the FPC cable 103 into the interface 104, which affects the docking efficiency. Based on the above technical problems, the inventor of the present application first found that an auxiliary frame that can move and insert the FPC cable 103 into the interface 104 on the base 1 can be set. The auxiliary frame is composed of two clamping plates 311. Guide grooves 312 are opened on the opposite sides of the two clamping plates 311, which are arranged between the FPC cable 103 and the interface 104 to guide the inserted FPC cable 103 to solve the deviation of the FPC cable 103 inserted into the interface 104. Specifically, reference can be made to the attached Figure 1 - attached Figure 5 ; During use, control the auxiliary frame to move between the FPC cable 103 and the interface 104, control the YZ-axis moving and picking mechanism 2 to push the TFT module 102 and the FPC cable 103 down and insert them into the guide grooves 312 opened on the auxiliary frame. At this time, control the auxiliary frame and the TFT module 102 to descend simultaneously. After aligning the guide grooves 312 with the interface 104, control the YZ-axis moving and picking mechanism 2 to push the FPC cable 103 down and insert it into the interface 104 again; However, further, when the inventors of the present application were actually using it, they found a problem that there may be a certain distance when the FPC cable 103 is inserted into the guide groove 312, and the FPC cable may shift during movement, affecting the docking efficiency. Based on the above technical problems, the inventors of the present application first found that a U-shaped frame 313 can be installed on the guide groove 312, where the width of the U-shaped frame 313 in the vertical direction decreases sequentially from top to bottom; the bottom width of the U-shaped frame 313 corresponds to the guide groove 312. By expanding the range of the top opening of the U-shaped frame 313 and according to the characteristic that its width in the vertical direction decreases sequentially from top to bottom, it is convenient for the FPC cable to be inserted. Specifically, reference can be made to the attached Figure 1 - attached Figure 5 ; During use, control the auxiliary frame to move between the FPC cable 103 and the interface 104, and control the YZ-axis moving material taking mechanism 2 to push the TFT module 102 and the FPC cable 103 down to insert them into the top end of the U-shaped frame 313. According to the characteristic that its width in the vertical direction decreases sequentially from top to bottom, guide them to the outlet below the U-shaped frame 313 and insert them into the guide groove 312 at the same time; then control the auxiliary frame and the TFT module 102 to descend simultaneously. After aligning the guide groove 312 with the interface 104, control the YZ-axis moving material taking mechanism 2 to push the FPC cable 103 down to insert it into the interface 104 again; Specifically, reference can be made to the attached Figure 1 - attached Figure 10, wherein the distance between the two clamping plates 311 can be adjusted, and a distance adjusting mechanism is provided. The distance adjusting mechanism includes: a mounting plate 504 and an adjusting plate 501. There are two groups of adjusting plates 501, which are respectively fixedly connected to the front end of one of the two clamping plates 311. The bottom end of the adjusting plate 501 is fixedly connected with a third sliding frame 503. The inner wall of the third sliding frame 503 is slidably connected with a third guide rail 502. The bottom end of the third guide rail 502 is fixedly connected to the top end of the mounting plate 504. On both sides of the bottom end of the mounting plate 504, a second telescopic cylinder 506 is fixedly connected respectively. The output ends of the second telescopic cylinders 506 on both sides are respectively fixedly connected to one of the two adjusting plates 501. There is a U-shaped connecting frame 505 between the output end of the second telescopic cylinder 506 and the adjusting plate 501. The bottom end of the U-shaped connecting frame 505 is connected to the output end of the second telescopic cylinder 506, and the top end is fixedly connected to the adjusting plate 501. During use, by controlling the two second telescopic cylinders 506 to drive the adjusting plate 501 to move, at the same time driving the third sliding frame 503 at the bottom end of the adjusting plate 501 to move along the third guide rail 502, and the clamping plate 311 at the top end of the adjusting plate 501 to move, the positions of the two clamping plates 311 and the distance between the two clamping plates 311 are adjusted. The function of adjusting the position is to control the two second telescopic cylinders 506 to drive the two clamping plates 311 to move in the same direction respectively through the U-shaped connecting frame 505 and the adjusting plate 501 according to the position of the FPC flexible cable 103. There are two ways of moving. One is overall translation. According to the different positions of the FPC flexible cable 103 in different TFT modules 102, the position of the clamping plate 311 is adjusted. The second is to adjust the distance between the clamping plates 311 in the same group. The second movement has two functions. One is to adjust the distance between the clamping plates 311 according to the width of the FPC flexible cable 103 to expand the use range. The other is when the FPC flexible cable 103 does not need to be guided, control the two second telescopic cylinders 506 to drive the two clamping plates 311 to move to both sides respectively through the U-shaped connecting frame 505 and the adjusting plate 501 to release the restriction on the FPC flexible cable 103; An XZ-axis moving mechanism 6 for driving it to lift and move forward and backward is installed at the bottom end of the mounting plate 504. The XZ-axis moving mechanism 6 drives the distance adjusting mechanism 5 and the clamping plate 311 to move forward and backward and lift; When the bottom end of the FPC flexible cable 103 is inserted into the interface 104 opened on the base 1 and it is no longer necessary to use the clamping plate 311 and the U-shaped frame 313 to guide the FPC flexible cable 103, control the distance adjusting mechanism 5 to drive the two clamping plates 311 and the U-shaped frame 313 to separate from the FPC flexible cable 103. After releasing the restriction on the FPC flexible cable 103, control the XZ-axis moving mechanism 6 to drive the clamping plate 311 and the U-shaped frame 313 to be withdrawn from the gap between the TFT module 102 and the backlight plate 101, and then control the YZ-axis moving and picking mechanism 2 to drive the TFT module 102 to continue to descend, install it on the backlight plate 101 in the base 1, and then reset.

[0020] Example 2: Refer to Figure 11 - Figure 15 , which is basically the same as Example 1. When the inventor of the present application was actually using it, it was found that the problem in the above solution was that when the FPC cable 103 was inserted into the U-shaped frame 313, both sides of one side of the bottom end of the FPC cable 103 might be in linear contact with the inner wall hypotenuse of the U-shaped frame 313, and the increased friction might cause the FPC cable 103 to fold, affecting the wiring efficiency. Based on the above problems, the guide groove 312 was removed. Further, both side walls of the U-shaped frame 313 were made into bendable metal plates 3131. When the U-shaped frames 313 on the two clamping plates 311 were driven by an external force to move away from each other, their side walls bent outward synchronously to form an outward-expanded guiding channel to broaden the wiring channel, as Figure 15 shown, which was convenient for the FPC cable 103 to be inserted. At the same time, point contact was formed between the inner wall of the metal plate 3131 and the inserted FPC cable 103, reducing the contact surface and avoiding the folding of the FPC cable 103; When the FPC cable 103 was inserted into the bottom opening of the U-shaped frame 313, the two U-shaped frames 313 were driven by an external force to move closer to each other, and their side walls returned to a straight state to guide the transmitted FPC cable 103; Specifically, reference can be made to the attached[[ID=~12]] Figures 11 - 14 , where the external force is an adjusting component. The adjusting component is installed between the U-shaped frame 313 and the clamping plate 311 and is used to drive the U-shaped frame 313 to move. The adjusting component includes: a guide frame 41, which is installed at the top of the clamping plate 311; a first sliding rod 42, which is installed on one side of the U-shaped frame 313, and the outer wall of which is slidably connected to the inner wall of the guide frame 41; and a first telescopic cylinder 43, which is fixedly installed on the side of the guide frame 41 away from the U-shaped frame 313, and the output end of the first telescopic cylinder 43 is fixedly connected to the end of the first sliding rod 42. By controlling the first telescopic cylinder 43 to pull the first sliding rod 42 to move, the U-shaped frame 313 is pulled to move through the first sliding rod 42; A second connecting rod 410 is fixedly connected to the outside of the metal plate 3131, and a pulling component is arranged between the outside of the second connecting rod 410 and the first sliding rod 42. When the first telescopic cylinder 43 pulls the first sliding rod 42 to move, the pulling component will pull the metal plate 3131 to bend outward to form an outward-expanded guiding channel; Specifically, reference can be made to the attached Figures 11 - 14, wherein the pulling assembly includes: a hinge rod 49, one end of the hinge rod 49 is rotatably connected to the outside of the second connecting rod 410, and the other end of the hinge rod 49 is rotatably connected to a first connecting rod 48; and a linkage mechanism installed between the other end of the first connecting rod 48 and the first sliding rod 42. When in use: the first sliding rod 42 is pulled to move by controlling the first telescopic cylinder 43, the U-shaped frame 313 is pulled to move by the first sliding rod 42, the first sliding rod 42 pulls the first connecting rod 48 to move through the linkage mechanism, and the first connecting rod 48 pulls the side wall metal plate 3131 of the U-shaped frame 313 to open outward through the hinge rod 49; The linkage mechanism includes: a rack 46, the rack 46 is fixedly installed at one end of the first connecting rod 48 away from the hinge rod 49; a linkage gear set 44 is rotatably connected to the top end of the guide frame 41; and teeth 45 are horizontally and arrayedly distributed at the top end of the first sliding rod 42; The linkage gear set 44 includes a rotating shaft, a first gear fixedly installed in the middle of the rotating shaft, and second gears fixedly installed at both ends of the rotating shaft. The rotating shaft is rotatably connected to the top end of the guide frame 41, the first gear is meshed with the teeth 45, and the second gears are meshed with the rack 46; the diameter of the second gear is larger than that of the first gear; a first sliding frame 471 is fixedly connected to the bottom end of the rack 46, and a first guide rail 472 is slidably connected to the inner wall of the first sliding frame 471; a second sliding frame 411 is fixedly installed at the bottom of the rotating connection between the first connecting rod 48 and the hinge rod 49, and a second guide rail 412 is slidably connected to the inner wall of the second sliding frame 411; Working principle: the first sliding rod 42 is pulled to move by controlling the first telescopic cylinder 43, the U-shaped frame 313 is pulled to move by the first sliding rod 42, the first sliding rod 42 drives the first gear to rotate through the teeth, the first gear drives the second gears to rotate through the rotating shaft, and the rack 46 is driven to move through the meshing of the second gears and the rack 46. Since the diameter of the second gear is larger than that of the first gear, when the first gear and the second gears rotate one circle at the same time, the moving distance of the first sliding rod 42 is less than the moving distance of the rack 46; the first connecting rod 48 is pulled to move through the movement of the rack 46, and the first connecting rod 48 pulls the side wall metal plate 3131 of the U-shaped frame 313 to open outward through the hinge rod 49.

[0021] Example 3: Refer to Figure 1 - Figure 16 , which is basically the same as Example 2. Further: a BL platform 803 is arranged below the base 1, a support column 801 is installed at the top end of the BL platform 803, a vacuum chuck is installed at the top end of the support column 801 for adsorbing the base 1, and an X-axis moving mechanism 8 for driving it to move back and forth is installed at the bottom end of the BL platform 803, so as to move the base 1 without inserting the FPC cable 103 to the lower part of the output end of the YZ-axis moving and picking mechanism 2 for installing the TFT module 102, and then move out the base 1 installed with the TFT module 102 for blanking.

[0022] Example 4: Refer toFigure 8 - Figure 10 , which is basically the same as Example 3, but further comprises: a suspension pulling mechanism 7 is installed on the BL platform 803, the top of the suspension pulling mechanism 7 corresponds to the interface 104 opened on the base 1, and the suspension pulling mechanism 7 includes a clamping cylinder 701, the two output ends of the top of the clamping cylinder 701 move relative to each other, and a clamping plate 702 is installed. The bottom end of the clamping cylinder 701 is provided with a pushing mechanism. When in use: when the TFT module 102 is installed and the FPC cable 103 is fully inserted into the interface 104 on the base 1, the pushing mechanism is controlled to push the clamping cylinder 701 up. , control the clamping cylinder 701 to drive the clamping plate 702 to clamp the FPC cable 103 passing through the interface 104. After clamping, control the pushing mechanism to descend, and the top of the pushing mechanism is separated from the clamping cylinder 701, releasing the supporting force on it, so that the clamping cylinder 701 is suspended, and the FPC cable 103 is straightened by the self-gravity of the clamping cylinder 701. During the clamping process, the clamping length may be different. The suspended clamping cylinder 701 can straighten the FPC cable 103 to avoid wrinkles, and also avoid material damage caused by hard straightening.

[0023] Specifically, the suspension pulling mechanism 7 includes a clamping cylinder 701, both output ends of which are fixedly connected to a clamping plate 702, a connecting plate 703 fixedly connected to the rear side of the clamping cylinder 701, a sliding frame 704 fixedly connected to the rear side of the connecting plate 703, a guide rail 705 slidably connected to the inner wall of the sliding frame 704, and the guide rail 705 is fixedly connected to the BL platform 803; The driving mechanism includes: an L-shaped lifting frame 709, the top rear side of the L-shaped lifting frame 709 is fixedly connected to a horizontal plate 706, the top surface of the horizontal plate 706 contacts the bottom of the connecting plate 703, the middle part of the L-shaped lifting frame 709 is threadedly connected to a threaded screw 708, the outer wall of the threaded screw 708 is rotatably connected to the BL platform 803, a motor 707 is fixedly installed on one side of the BL platform 803, the output end of the motor 707 and the bottom end of the threaded screw 708 are connected by a belt and a pulley transmission, and both sides of the front end of the L-shaped lifting frame 709 are fixedly connected to a sliding frame 5 710, and the inner wall of the sliding frame 5 710 is slidably connected to a guide rail 5 711; Working principle: When the TFT module 102 is installed and the FPC cable 103 is fully inserted into the interface 104 on the base 1, the control motor 707 drives the threaded lead screw 708 to rotate through the transmission of the belt and the pulley. The threaded lead screw 708 drives the L-shaped lifting frame 709 to rise, and at the same time drives the slide frame five 710 fixedly connected to both sides of the front end of the L-shaped lifting frame 709 to move along the guide rail five 711 to guide the lifting of the L-shaped lifting frame 709. The rising of the L-shaped lifting frame 709 will drive the cross plate 706 to rise, and the cross plate 706 will push the connecting plate 703 to rise. When the connecting plate 703 rises, it will drive the slide frame four 704 and the clamping cylinder 701 to rise. The slide frame four 704 rises along the guide rail four 705. The control clamping cylinder 701 drives the clamping plate 702 to clamp the FPC cable 103 passing through the interface 104. After clamping, the control pushing mechanism descends, and the top of the cross plate 706 of the pushing mechanism is separated from the connecting plate 703, releasing the supporting force on it, so that the clamping cylinder 701 floats. The self-weight of the clamping cylinder 701 is used to straighten the FPC cable 103. During the clamping process, the lengths of the clamped parts may be different. When the floating clamping cylinder 701 straightens the FPC cable 103 to eliminate wrinkles, it also avoids material damage caused by hard straightening.
