Description

Technical Field

[0001] This utility model relates to the field of flexible circuit board manufacturing technology, specifically to a flexible circuit board manufacturing fixing clamp structure. Background Technology

[0002] Flexible printed circuit boards (FPCBs) are flexible electronic interconnect components made of flexible substrates such as polyimide (PI) or polyester (PET). They are widely used in consumer electronics, medical devices, automotive electronics, and other fields. During the production of FPCBs, when drilling or cutting them, a fixing clamp structure is required to fix the FPCBs in place to ensure that they do not shift during processing.

[0003] Traditional clamping structures can only effectively secure single-layer flexible circuit boards. When the flexible circuit board is multi-layered, the edges are difficult to align, resulting in the edges of the multi-layered flexible circuit boards not being able to completely overlap. Traditional clamping plates are on a vertical plane, making it impossible to clamp and secure the edges of each layer of flexible circuit board, or to clamp and secure flexible circuit boards of different sizes and widths at the same time. This results in low applicability, and the clamping force cannot be flexibly adjusted according to the actual clamping pressure required to avoid clamping marks or damage to the flexible substrate. Utility Model Content

[0004] To address the limitations of traditional clamping structures, which can only effectively secure single-layer flexible circuit boards (PCBs), and the difficulty in aligning the edges of multi-layer PCBs, resulting in incomplete overlap, and the fact that traditional clamping plates are on a vertical plane, making it impossible to clamp and secure the edges of each layer of PCBs simultaneously, or to clamp PCBs of different widths at once, thus limiting applicability, and failing to flexibly adjust the clamping force according to actual clamping pressure requirements to avoid clamp marks or damage to the flexible substrate, this invention provides a PCB manufacturing clamping structure.

[0005] A flexible circuit board manufacturing clamping structure includes a worktable with two sets of clamping assemblies. Each set of clamping assemblies includes a bidirectional lead screw rotatably mounted on the worktable surface. A clamping plate is movably mounted on the outer wall of the bidirectional lead screw. Several telescopic rods are fixedly mounted on the top and side walls of each clamping plate. A clamping block is fixedly mounted on the telescopic end of each telescopic rod. A buffer layer and a pressure sensor are fixedly mounted on the side wall of the clamping block. A reciprocating lead screw is rotatably mounted above the two sets of clamping assemblies, and a production workpiece is movably mounted on the outer wall of the reciprocating lead screw.

[0006] Furthermore, two grooves are fixedly installed on the workbench surface, and a bidirectional lead screw is rotatably installed in each groove. A guide groove is fixedly installed on the bottom wall of the groove. The clamping plate has an L-shaped structure, and its bottom end is threaded to the outer wall of the bidirectional lead screw. It can move left and right in the guide groove. One end of the bidirectional lead screw passes through the side wall of the groove and is fixedly installed with a crank handle.

[0007] Furthermore, each clamping plate has a receiving groove fixedly installed on its top and side walls, and a support plate is fixedly installed inside the receiving groove. Several micro motors are fixedly installed on the support plate by a mounting bracket, and a telescopic rod is fixedly installed at the output end of each micro motor.

[0008] Furthermore, several clamping blocks are evenly distributed, and a buffer layer is fixedly installed on the inner wall opposite the clamping blocks. The buffer layer is made of rubber, and the pressure sensor is fixedly installed inside the buffer layer.

[0009] Furthermore, a support frame is fixedly installed on the workbench table, and a guide groove is also fixedly installed on the top wall of the support frame. The reciprocating screw is rotatably installed at the top of the support frame, with one end passing through the support frame and fixedly connected to the output shaft of the positive and negative motor installed on the outer wall of the support frame. The production workpiece includes a movable seat, the top of which is movably installed inside the guide groove, and the bottom of which is threadedly connected to the outer wall of the reciprocating screw.

[0010] Furthermore, a drilling machine is installed on the bottom wall of the mobile seat via a mounting bracket, and a control panel is fixedly installed on the top wall of the support frame. The control panel is electrically connected to several micro motors, forward and reverse motors, and pressure sensors.

[0011] Compared with the prior art, the advantages of this utility model are: it can punch or cut multiple layers of flexible circuit boards at one time. When the width of each layer of circuit board is different, different clamping blocks can be used to fix and clamp the side wall of each layer of circuit board. It can punch or cut one or more layers of flexible circuit boards of different widths at the same time, which is highly flexible. At the same time, after the pressure value is preset in the PLC control system inside the control panel, the pressure sensor can sense the change of pressure value during the clamping process. When the pressure value reaches the preset pressure value on the control system, the clamping force is stopped, which can avoid clamping marks or damage to the flexible substrate.

The following will refer to the accompanying drawings. Figures 1-5 The present invention will be described in detail with reference to the embodiments.

[0019] A flexible circuit board production clamping structure includes a workbench 1 with two sets of clamping assemblies 2. A multi-layered flexible circuit board is placed on the table of the workbench 1 and below the two sets of clamping assemblies 2. A production workpiece 10 is placed between the two sets of clamping assemblies 2. The two sets of clamping assemblies 2 first fix and press the multi-layered flexible circuit board, and then the production workpiece 10 in the middle is used to punch holes or cut the pressed multi-layered flexible circuit board.

[0020] Each set of fixed clamping components 2 includes a bidirectional lead screw 3 rotatably mounted on the tabletop of the workbench 1. A set of clamping plates 4 are movably mounted on the outer wall of the bidirectional lead screw 3. Two grooves 11 are fixedly mounted on the tabletop of the workbench 1. A bidirectional lead screw 3 is rotatably mounted in each groove 11. A guide groove 12 is fixedly mounted on the bottom wall of the groove 11. The clamping plate 4 has an L-shaped structure. Its bottom end is threaded to the outer wall of the bidirectional lead screw 3 and can move left and right in the guide groove 12. One end of the bidirectional lead screw 3 passes through the side wall of the groove 11 and is fixedly mounted with a crank handle 13.

[0021] After placing the multi-layer flexible circuit board on the workbench 1, the clamping plates 4 are initially adjusted using the bidirectional lead screw 3 according to their width, so that the clamping plates 4 at both ends are close to the side wall of the flexible circuit board. The crank handle 13 is then turned to rotate the bidirectional lead screw 3, further bringing the clamping plates 4 closer together. This initial proximity to the side wall of the flexible circuit board minimizes the need for excessive extension when using the telescopic rod 5 to fix the board to the side wall, thus avoiding instability caused by excessive extension. The clamping plates 4 move left and right within the guide groove 12, further enhancing their stability during movement and also serving a guiding function.

[0022] Each clamping plate 4 has several telescopic rods 5 fixedly installed on its top and side walls. Each telescopic rod 5 has a clamping block 6 fixedly installed at its telescopic end. Each clamping plate 4 has a receiving groove 14 fixedly installed on its top and side walls. A support plate 15 is fixedly installed inside the receiving groove 14. Several micro motors 16 are fixedly installed on the support plate 15 by means of a mounting bracket. Each micro motor 16 has a telescopic rod 5 fixedly installed at its output end.

[0023] First, start the micro motor 16 on the top wall of the clamping plate 4, so that it drives the telescopic rod 5 to move downward until the clamping block 6 presses against the top wall of the multilayer flexible circuit board. Then, start the micro motor 16 on the side wall of the clamping plate 4, so that it drives the telescopic rod 5 to move left and right until the clamping block 6 contacts the two side walls of the multilayer flexible circuit board and clamps and fixes the side walls.

[0024] Several clamping blocks 6 are evenly distributed. A buffer layer 7 and a pressure sensor 8 are fixedly installed on the side wall of the clamping block 6. The buffer layer 7 is fixedly installed on the inner wall opposite to the clamping block 6 and is made of rubber. The pressure sensor 8 is fixedly installed inside the buffer layer 7.

[0025] A support frame 17 is fixedly installed on the tabletop of the workbench 1. A control panel 19 is fixedly installed on the top wall of the support frame 17. The control panel 19 is electrically connected to several micro motors 16, forward and reverse motors 18, and pressure sensors 8. The control panel 19 is equipped with a PLC control system. The PLC control system can control the several micro motors 16, forward and reverse motors 18, and pressure sensors 8. The control panel 19 is electrically connected to an external power supply.

[0026] The optimal pressure value that the pressure sensor 8 can sense can be preset inside the PLC control system. When the pressure value sensed by the pressure sensor 8 reaches the same as the preset pressure value, the PLC control system controls the micro motor 16 to stop. In other words, the telescopic rod 5 stops extending. At this time, the clamping force of the clamping block 6 on the top and side walls of the flexible circuit board is appropriate, which can play a fixing role without causing clamping marks or damaging the flexible substrate.

[0027] A reciprocating screw 9 is rotatably mounted above the two sets of fixed clamp assemblies 2. A guide groove 12 is also fixedly mounted on the top wall of the support frame 17. The reciprocating screw 9 is rotatably mounted on the top of the support frame 17. One end of the screw passes through the support frame 17 and is fixedly connected to the output shaft of the forward and reverse motor 18 mounted on the outer wall of the support frame 17. The forward and reverse motor 18 is mounted on the outer wall of the support frame 17 through a mounting bracket and can achieve forward and reverse rotation. The forward and reverse motor 18 is started by controlling the control panel 19, which allows the moving seat 20 to move left and right along the guide groove 12, thereby performing left and right movement drilling or cutting on the multi-layer flexible circuit board below.

[0028] A production workpiece 10 is movably mounted on the outer wall of the reciprocating lead screw 9. The production workpiece 10 includes a movable seat 20. The top of the movable seat 20 is movably mounted inside the guide groove 12. The bottom of the movable seat 20 is threadedly connected to the outer wall of the reciprocating lead screw 9. A punching machine 21 or a cutting blade is mounted on the bottom wall of the movable seat 20 through a mounting bracket. The production workpiece 10 includes a punched workpiece or a cut workpiece. After the two sets of fixing clamp assemblies 2 fix the multilayer flexible circuit board, the punching machine 21 or the cutting blade is used to punch or cut it. The punching machine 21 or the cutting blade is a commonly used punching and cutting structure in the prior art, which can punch and cut the circuit board.

[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
