[0002] Flexible printed circuits (FPC) are thin and light, so they are the best choice for most smart electronic products. However, they are also prone to folding, scratching, etc. during use, and have low mechanical strength and are prone to cracking. Therefore, reinforcing sheets are needed to enhance the mechanical strength of the flexible printed circuit board and facilitate the installation of parts on the surface of the flexible printed circuit board.

[0003] In the process of attaching the reinforcing sheet, it is usually necessary to manually remove the reinforcing sheet from the material strip and attach it to the FPC board, which has high labor and time costs. Some use reinforcing sheet attaching equipment for attaching, but the robot of the attaching equipment needs to grab the reinforcing sheet on the material strip and then move the reinforcing sheet to the position of the flexible circuit board, that is, the robot needs to constantly move back and forth between the material strip and the flexible circuit board, and can only attach one reinforcing sheet at a time, resulting in low working efficiency of the reinforcing sheet attaching equipment in the prior art.

[0019] The technical scheme in the embodiment of the present invention is described clearly and completely below in conjunction with the accompanying drawings in the embodiment of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0020] See also Figures 1 to 7 As shown, a reinforcing sheet bonding device for a flexible circuit board includes a workbench 1, a receiving component 2, two conveying components 3 and two bonding components 4. The receiving component 2 is arranged on the workbench 1, and is used to receive an FPC board 10 (an FPC board to be bonded with reinforcing sheets). The two conveying components 3 are arranged on the workbench 1 at intervals and are located on both sides of the length direction of the workbench 1. The receiving component 2 is located between the two conveying components 3. The two bonding components 4 are slidably arranged above the workbench 1. During implementation, the two bonding components 4 are used to staggeredly transfer the reinforcing sheets 36 on the two conveying components 3 to above the receiving component 2, and bond the reinforcing sheets 36 to the FPC board 10.

[0021] It should be noted that after the reinforcing sheet 36 is bonded to the FPC board 10, it is necessary to press it together at a certain temperature and pressure for a preset time to better bond the reinforcing sheet 36 to the FPC board 10. By setting two bonding components 4, the two bonding components 4 alternately bond the reinforcing sheets 36 on the two conveying components 3 to the FPC board 10 to improve work efficiency. For example, when one of the bonding components 4 is pressing and bonding the reinforcing sheet 36, the other bonding component 4 moves to the top of the conveying component 3 on the corresponding side to absorb the reinforcing sheet 36; when one of the bonding components 4 is bonded, it moves to the top of the conveying component 3 on the corresponding side and absorbs the reinforcing sheet 36, and at this time, the other bonding component 4 bonds the absorbed reinforcing sheet 36 to the FPC board 10. In this reciprocating manner, the two bonding components 4 alternately bond the reinforcing sheets 36 to the FPC board 10, thereby enhancing work efficiency.

[0022] See also Figure 1 , Figure 4As shown, in this embodiment, a frame 12 is fixedly provided on the top of the workbench 1, and two bonding components 4 are slidably arranged on the frame 12. Each bonding component 4 includes a first slide plate 41, a first lifting plate 42, a first telescopic cylinder 43, a first power unit 44 and a plurality of manipulators 45. The first slide plate 41 is slidably connected to the frame 12, and its sliding direction is parallel to the length direction of the workbench 1, that is, the first slide plate 41 can slide between the receiving component 2 and the conveying component 3. The first lifting plate 42 is arranged below the first slide plate 41, and the first telescopic cylinder 43 is fixed above the first slide plate 41. The output end 32 of the first telescopic cylinder 43 passes through the first slide plate 41 and is fixedly connected to the first lifting plate 42, thereby driving the first lifting plate 42 to rise and fall, and a plurality of manipulators 45 are fixedly arranged on the bottom surface of the first lifting plate 42.

[0023] It should be noted that the manipulator 45 is a mechanical gripper used in the prior art for sucking the reinforcing sheet 36, wherein the manipulator 45 has the function of sucking the reinforcing sheet 36 and the function of heating the reinforcing sheet 36 to melt the adhesive on the reinforcing sheet 36 so that the reinforcing sheet 36 and the FPC board 10 are fully bonded together, which will not be described in detail here. In addition, in this embodiment, there are multiple manipulators 45, and the multiple manipulators 45 can be arranged at intervals according to actual requirements, thereby, multiple reinforcing sheets 36 can be grabbed by multiple manipulators 45, and then multiple reinforcing sheets 36 are bonded to the FPC board 10 to better improve work efficiency.

[0024] The first power unit 44 is used to drive the first slide plate 41 to slide along the length direction of the workbench 1. Specifically, the two first power units 44 of the two laminating components 4 each include a first lead screw 441 and a first motor 442. Figure 1 As shown, the first slide plates 41 of the two laminating components 4 are respectively located on both sides of the length direction of the workbench 1 and are slidably connected to the frame 12. The first lead screws 441 of the two first power units 44 are arranged at intervals and are respectively rotatably connected to the two side walls of the length direction of the frame 12. The two first motors 442 are fixedly arranged on one side of the frame 12 and are respectively fixedly connected to the two first lead screws 441, thereby respectively driving the two first lead screws 441 to rotate. The two first lead screws 441 are respectively screwed to the two first slide plates 41 and are slidably connected to the other first slide plate 41.

[0025] Please continue reading Figure 4As shown, it should be noted that since the two first slide plates 41 have the same horizontal height, both of the two first lead screws 441 pass through the two first slide plates 41. However, each first lead screw 441 is screwed to one of the first slide plates 41 and is slidably connected to the other first slide plate 41. Thus, each first lead screw 441 can only drive the first slide plate 41 screwed thereto to reciprocate along the length direction of the workbench 1. For example, during implementation, when one of the first motors 442 is started, the first motor 442 drives the corresponding first lead screw 441 to rotate forward or backward, and the first slide plate 41 screwed to the first lead screw 441 reciprocates along the axial direction of the first lead screw 441. Since the other first slide plate 41 is slidably connected to the first lead screw 441, it will not move with the rotation of the first lead screw 441.

[0026] In this embodiment, both of the two conveying assemblies 3 include an input end 31 and an output end 32. Two fitting assemblies 4 are located above the output end 32 of the conveying assemblies 3. Above the input ends 31 of the two conveying assemblies 3, a loading plate 6 and a discharging plate 7 are respectively fixedly installed. The receiving assembly 2 is slidably connected to the workbench 1, and the sliding direction of the receiving assembly 2 is the same as the conveying direction of the conveying assemblies 3. On one side of the workbench 1, a second power unit 23 for driving the sliding of the receiving assembly 2 is provided.

[0027] Please refer to Figure 1 and Figure 3 As shown, specifically, two slide rails 11 are fixedly installed at intervals on the top surface of the workbench 1, and the central axes of the two slide rails 11 are parallel to the conveying direction of the conveying assemblies 3. The receiving assembly 2 includes a receiving plate 21 and a fixing block 22. The two sides of the bottom surface of the receiving plate 21 are slidably connected to the two slide rails 11, so that the receiving assembly 2 reciprocates along the conveying direction of the conveying assemblies 3. The fixing block 22 is fixedly installed at the bottom end of the receiving plate 21 and is located between the two slide rails 11. The second power unit 23 includes a second lead screw 231 and a second motor 232. The second lead screw 231 is rotatably arranged on the top surface of the workbench 1, the axial direction of the second lead screw 231 is parallel to the conveying direction of the conveying assemblies 3, and is screwed to the fixing block 22. The second motor 232 is fixedly installed on one side of the workbench 1, and its output end is fixedly connected to one end of the second lead screw 231. During implementation, by rotating the second motor 232 forward or backward, the second lead screw 231 is driven to rotate forward or backward, and then the fixing block 22 and the receiving plate 21 are driven to reciprocate along the conveying direction of the conveying assemblies 3. By setting the receiving assembly 2 to be slidably connected, it is convenient to transfer the FPC board 10.

[0028] Please refer to Figure 1 and Figure 2As shown, in this embodiment, a feeding component 5 is slidably arranged on the frame body 12. The feeding component 5 is used to transfer the FPC board 10 on the loading board 6 to the receiving component 2, and at the same time transfer the materials on the receiving component 2 to the discharging board 7. During implementation, the receiving component 2 is moved between the loading board 6 and the discharging board 7 by the second power unit 23. At this time, there are multiple FPC boards 10 with reinforcing patches 36 to be pasted on the loading board 6. Then, the feeding component 5 is started to transfer the FPC board 10 to the receiving component 2. Next, the second power unit 23 transfers the receiving component 2 and the FPC board 10 placed on the receiving component 2 to the lower part of the laminating component 4, so as to laminate the reinforcing patch 36 on the FPC board 10 through the laminating component 4. After the FPC board 10 and the reinforcing patch 36 are laminated, the receiving component 2 is transferred back between the loading board 6 and the discharging board 7 by the second power unit 23. Then, the FPC board 10 on the receiving component 2 is transferred to the discharging board 7 through the feeding component 5, and at the same time the FPC board 10 on the loading board 6 is transferred to the receiving component 2. The above steps are repeated until multiple FPC boards 10 are all pasted with reinforcing boards.

[0029] By providing the loading board 6, the discharging board 7 and the feeding component 5, the laminating device of the present application can automatically laminate the FPC board 10, reducing the labor cost. Preferably, a plurality of positioning holes (not shown in the figure) are respectively formed in each FPC board 10, and positioning pins 61 are respectively fixed on the loading board 6 and the discharging board 7 corresponding to each positioning hole. The plurality of positioning pins 61 are respectively inserted into the plurality of positioning holes to position the FPC board 10.

[0030] In this embodiment, the feeding component 5 includes a second slide plate 51, a third power unit 52, two second lifting plates 53, two second telescopic cylinders 54 and a plurality of grippers 55. The second slide plate 51 is located on the side of the workbench 1 away from the laminating component 4 and is slidably arranged on the frame body 12. The two second lifting plates 53 are arranged at intervals below the second slide plate 51, and the two second lifting plates 53 respectively correspond to the loading board 6 and the receiving component 2 or respectively correspond to the discharging board 7 and the receiving component 2. The two second telescopic cylinders 54 are fixed on the top surface of the second slide plate 51. The output ends of the two second telescopic cylinders 54 pass through the second slide plate 51 and are respectively fixedly connected to the two second lifting plates 53, thereby driving the two second lifting plates 53 to lift respectively.

[0031] A plurality of grippers 55 are evenly distributed on the bottom surface of the second lifting plate 53 for gripping the FPC board 10. Specifically, the gripper 55 is a suction gripper of the prior art, which is a device that uses the negative pressure principle to adsorb the surface of an object through a suction cup to achieve gripping and handling, and will not be elaborated here. Four grippers 55 are respectively fixedly arranged on the bottom surface of each second lifting plate 53, and the four grippers 55 are respectively fixedly arranged at the four corners of the corresponding bottom surface of the second lifting plate 53 to grip the four corners of the FPC board 10 by adsorption and transfer the FPC board 10 to a designated position.

[0032] The third power unit 52 includes a third motor 521 and a third lead screw 522. The axial direction of the third lead screw 522 is parallel to the length direction of the workbench 1. Its two ends are rotatably connected to the frame 12 and are also screwed to the second slide plate 51. The third motor 521 is fixedly arranged on one side of the frame 12, and its output end is fixedly connected to one end of the third lead screw 522 to drive the third lead screw 522 to rotate forward or backward. During implementation, the second slide plate 51 is moved above the loading plate 6 and the receiving plate 21 through the third motor 521 and the third lead screw 522. Two second telescopic cylinders 54 are started, and the two second telescopic cylinders 54 respectively drive the two second lifting plates 53 to move towards the direction close to the workbench 1 to respectively suck the FPC boards 10 on the loading plate 6 and the receiving plate 21 through a plurality of grippers 55. Then, the second slide plate 51 is transferred above the unloading plate 7 and the receiving plate 21 through the third motor 521 and the third lead screw 522 to transfer the FPC board 10 on the loading plate 6 to the receiving plate 21, and at the same time transfer the FPC board 10 with the reinforcing patch 36 already attached on the receiving plate 21 to the unloading plate 7, thereby achieving the purpose of automatic loading and automatic unloading.

[0033] Please refer to Figure 4 As shown, in this embodiment, each conveying assembly 3 includes a feeding reel 33, a winding reel 34, and a tape 35. The feeding reel 33 and the winding reel 34 are rotatably arranged under the workbench 1 and are respectively located on both sides of the workbench 1 in the width direction. The tape 35 is wound around the feeding reel 33, and a reinforcing patch 36 is adhered to the tape 35. Feeding ports 13 and discharging ports 14 that penetrate up and down are respectively formed on both sides of the workbench 1 corresponding to the feeding reel 33 and the winding reel 34. One end of the tape 35 passes through the feeding port 13 from bottom to top and extends towards the direction close to the discharging port 14, and then passes through the discharging port 14 from top to bottom and is wound around the outside of the winding reel 34. By arranging the feeding reel 33 and the winding reel 34 on the bottom surface of the workbench 1, the bonding device structure of this application is made more compact and the space occupation is reduced. The tape 35 is arranged on the top surface of the workbench 1 to facilitate the bonding assembly 4 to suck the reinforcing plate.

[0034] It should be noted that a driving motor 37 is provided on one side of the material receiving reel 34 to drive the material receiving reel 34 to rotate, thereby driving the material tape 35 to move towards the material receiving reel 34. Preferably, tension rollers 38 are respectively rotatably provided at the material inlet 13 and the material outlet 14 to make the movement of the material tape 35 smoother.

[0035] Please refer to Figure 1 , Figure 2 As shown, in this embodiment, the loading plate 6 and the unloading plate 7 have the same structure, both being U-shaped plates. The two material tapes 35 located above the workbench 1 respectively pass through the loading plate 6 and the unloading plate 7. Heating plates (not shown in the figure) are respectively provided inside the loading plate 6 and the unloading plate 7 to preheat the adhesive on the reinforcing sheet 36, so as to better adhere the reinforcing sheet 36 to the FPC board 10.

[0036] Preferably, guiding assemblies 39 are provided on both the loading plate 6 and the unloading plate 7 for limiting the corresponding material tapes 35 to prevent the material tapes 35 from skewing during movement. Specifically, each guiding assembly 39 includes a left-right lead screw 391 and two guiding rods 392. The left-right lead screw 391 is rotatably provided on the top surface of the loading plate 6, and the axial direction of the left-right lead screw 391 is perpendicular to the extending direction of the material tape 35. The top ends of the two guiding rods 392 are respectively screwed to both axial ends of the left-right lead screw 391. The loading plate 6 and the unloading plate 7 are respectively provided with sliding grooves 71 corresponding to the left-right lead screw 391. The free ends of each guiding rod 392 respectively pass through the sliding grooves 71 and extend towards the direction close to the workbench 1. Specifically, the free ends of the two guiding rods 392 respectively extend to both sides of the corresponding material tape 35 to limit the material tape 35.

[0037] During implementation, by rotating the left-right lead screw 391, at this time the two guiding rods 392 slide in the sliding grooves 71 and move towards each other or away from each other respectively until the bottom ends of the two guiding rods 392 abut against both sides of the material tape 35 to limit the material tape 35. By providing the left-right lead screw 391, it can adapt to material tapes 35 of different widths. Preferably, two guiding assemblies 39 are respectively provided on the loading plate 6 and the unloading plate 7. The two guiding assemblies 39 are respectively located on both sides of the opening direction of the corresponding loading plate 6 or unloading plate 7 to further limit the corresponding material tape 35. Preferably, a handle is fixedly provided at one end of the left-right lead screw 391 to facilitate the staff to rotate the left-right lead screw 391.

[0038] Please refer to Figure 3 , Figure 5 and Figure 7As shown, preferably, in this embodiment, a plurality of limiting components 8 are provided on the workbench 1 below the fitting component 4. The plurality of limiting components 8 are distributed on both sides in the width direction of each strip 35. While the guiding component 39 limits the strip 35 left and right, the limiting component 8 can further limit the strip 35 in the up and down directions. Specifically, each limiting component 8 includes a Z-shaped plate 81 and a threaded rod 82. One end of the Z-shaped plate 81 is suspended above the corresponding side of the strip 35 to limit the strip 35 and prevent the strip 35 from being lifted when the fitting component 4 sucks the reinforcing sheet 36 on the strip 35. The bottom end of the threaded rod 82 passes through the end of the Z-shaped plate 81 far from the corresponding strip 35 and is fixedly connected to the workbench 1 and is slidably connected to the Z-shaped plate 81. A nut 83 is screwed on the top end of the threaded rod 82. A first spring 84 is sleeved on the outer side of the threaded rod 82. Two ends of the first spring 84 respectively abut against the nut 83 and the Z-shaped plate 81.

[0039] Please continue to refer to Figure 7 As shown, taking the plurality of limiting components 8 on both sides in the width direction of one strip 35 as an example, the plurality of limiting components 8 are evenly distributed on both sides in the width direction of the strip 35, and the Z-shaped plates 81 on both sides in the width direction of the strip 35 are arranged in a mirror image. The ends of the plurality of Z-shaped plates 81 close to the strip 35 are respectively suspended above both sides in the width direction of the strip 35 to limit the strip 35. It can be understood that when the strip 35 moves upward due to the fitting component 4 pulling the reinforcing sheet 36, since the Z-shaped plates 81 on both sides are slidably connected to the threaded rod 82, they can slide upward along the axial direction of the threaded rod 82. At this time, the first spring 84 is compressed and the Z-shaped plate 81 moves upward. After the fitting component 4 sucks the reinforcing sheet 36, the Z-shaped plate 81 is reset by the elasticity of the first spring 84, thereby resetting the strip 35. By arranging the Z-shaped plate 81 in cooperation with the threaded rod 82, the first spring 84 and the nut 83, the problem that the strip 35 is deformed due to pulling the strip 35 during the process of the fitting component 4 sucking the reinforcing sheet 36 is avoided. At the same time, by arranging the nut 83 to be screwed on the threaded rod 82, the relative position of the nut 83 and the threaded rod 82 can be adjusted, that is, the relative height of the nut 83 on the threaded rod 82, and further the pressure of the first spring 84 on the Z-shaped plate 81 can be adjusted.

[0040] Please refer to Figure 1 and Figure 6As shown in the figure, in this embodiment, clamping components 9 are respectively arranged on both sides of the top surface of the receiving plate 21 for clamping the FPC board 10 located on the top surface of the receiving plate 21, so as to prevent the FPC board 10 from shifting during the movement of the receiving plate 21 or the fitting process of the fitting component 4, resulting in deviation of the fitting position. Specifically, grooves 211 are respectively formed on both sides of the receiving plate 21 in the direction close to the loading plate 6 and the unloading plate 7. Each clamping component 9 includes a pressing plate 91 arranged on the top surface of the receiving plate 21 and a semi-toothed gear 92 rotatably arranged in the groove 211. One radial side of the semi-toothed gear 92 is fixedly connected to the bottom surface of the pressing plate 91. Thus, by rotating the semi-toothed gear 92, the pressing plate 91 can be driven to rotate. A relief groove 212 communicating with the outside is arranged at the bottom end of the groove 211. A rack 93 meshing with the semi-toothed gear 92 is slidably arranged in the relief groove 212. One end of the rack 93 passes through the relief groove 212 and extends in the direction close to the corresponding loading plate 6 or unloading plate 7. A second spring 94 for pushing the rack 93 to move away from the receiving plate 21 is arranged in the relief groove 212. Pressing blocks 72 are respectively convexly arranged on one side of the loading plate 6 and the unloading plate 7 close to the receiving plate 21. When the receiving plate 21 moves to one side of the pressing block 72, the pressing block 72 presses the corresponding rack 93 into the interior of the relief groove 212.

[0041] During implementation, when the receiving plate 21 is located below the fitting component 4, the clamping components 9 clamp both sides of the FPC board 10 to position the FPC board 10. When the FPC board 10 on the receiving plate 21 is fitted with the reinforcing sheet 36, the second power unit 23 drives the receiving plate 21 to move towards the loading plate 6 and the unloading plate 7. At this time, the ends of the racks 93 of the two clamping components 9 away from the receiving plate 21 respectively abut against one side of the corresponding loading plate 6 and the unloading plate 7, causing the racks 93 to move towards the receiving plate 21. Since the racks 93 are meshed with the semi-toothed gears 92, the semi-toothed gears 92 will be driven to rotate, and then the pressing plates 91 will be driven to rotate. Specifically, the racks 93 can drive the free ends of the pressing plates 91 to rotate upwards, that is, the pressing plates 91 are adjusted from a horizontal state to a vertical state. At this time, the pressing plates 91 no longer press the FPC board 10, and the feeding component 5 can transfer the FPC board 10 on the receiving plate 21 to the unloading plate 7, and at the same time, the feeding component 5 transfers the FPC board 10 to be pasted with the reinforcing sheet 36 on the loading plate 6 to the receiving plate 21.

[0042] When the second power unit 23 transfers the receiving plate 21 to below the fitting component 4, the ends of the racks 93 away from the receiving plate 21 are disengaged from the abutment of the pressing blocks 72. Through the elastic reset of the second spring 94, the racks 93 move away from the receiving plate 21. Thus, the semi-toothed gears 92 are driven to rotate, and then the pressing plates 91 are reset and re-pressed on the FPC board 10 to limit the FPC board 10.

[0043] In the specific implementation of the present invention, the staff places the FPC boards 10 to which multiple reinforcing sheets 36 are to be pasted on the loading board 6. At this time, the two conveying components 3 are already installed (one end of the tape 35 on the unwinding reel 33 passes through the feeding port 13 and the discharging port 14 and then winds around the winding reel 34), and then the feeding component 5 is started. The feeding component 5 transfers the FPC board 10 located on the loading board 6 to the receiving component 2 (at the same time, the FPC board 10 on the receiving component 2 to which the reinforcing sheet 36 has been pasted is transferred to the discharging board 7). Then, the second power unit 23 is started, and the second power unit 23 drives the receiving plate 21 to move below the fitting component 4. During this process, the clamping component 9 clamps the FPC board 10 located on the receiving plate 21 to prevent the FPC board 10 from shifting. Then, the two fitting components 4 are started, and the two fitting components 4 staggeredly transfer the reinforcing sheets 36 on the two conveying components 3 above the receiving component 2 and paste the reinforcing sheets 36 on the FPC board 10. Repeat this cycle until the pasting of multiple FPC boards 10 is completed.

[0044] In the present invention, by arranging two fitting devices to staggeredly paste the reinforcing sheets 36 on the two conveying components 3 onto the FPC board 10, the working efficiency is improved. By arranging the loading board 6, the discharging board 7, the receiving component 2 slidably arranged on the workbench 1, and the feeding component 5, the fitting device of the present invention can automatically complete the pasting of the reinforcing sheets 36 on the FPC board, improving the working efficiency and saving labor costs at the same time. It should be noted that during the process of the fitting component 4 pasting the reinforcing sheet 36, the second power unit 23 can adjust the relative position of the receiving plate 21 and the second lead screw 231 to cooperate with the multiple manipulators 45 of the fitting component 4 to complete the pasting of the FPC board 10 and the reinforcing sheet 36.

[0045] By arranging the guiding component 39 to limit the tape 35 of the conveying component 3, it is avoided that the tape 35 shifts during the movement. By arranging the limiting component 8, while the guiding component 39 limits the tape 35 left and right, the limiting component 8 can further limit the tape 35 in the up and down directions; by arranging the clamping component 9, it is avoided that the FPC board 10 shifts during the movement of the receiving plate 21 or the fitting process of the fitting component 4, resulting in deviation of the fitting position.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.
