Description

Technical Field

[0001] This utility model relates to the field of electronic manufacturing equipment, and in particular to a flip-up clamping mechanism for copper plating of PCB circuit boards. Background Technology

[0002] Traditional PCB copper plating clamping devices often suffer from insufficient positioning accuracy and difficulty in adapting to different PCB sizes. Furthermore, rigid clamping can easily damage the surface or internal circuitry of the PCB. Insufficient positioning accuracy is primarily due to their use of fixed clamping structures, lacking a dynamic adjustment mechanism and unable to precisely adjust to differences in the PCB's positioning hole positions. Difficulty in adapting to different PCB sizes stems from the limited range of clamping sizes and positioning methods, failing to meet the diverse needs of PCBs in terms of size, shape, and positioning hole layout. Rigid clamping damages the PCB because these devices often use rigid metal clamps for direct compression and fixation, lacking the ability to adaptively adjust clamping force. When the PCB is thin or has many surface components, this can easily cause scratches, deformation, and even internal circuit breaks or short circuits, impacting product quality and production efficiency.

[0003] While existing technologies can achieve certain clamping functions during use, they suffer from drawbacks: they lack the ability to adapt to different PCB board positioning functions and flexible protection structures. In view of this, we propose a flip-up clamping mechanism for copper plating of PCB circuit boards, which solves the above problems. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a flip-up clamping mechanism for copper plating of PCB circuit boards.

[0005] The technical solution of this utility model is as follows: A flip-up clamping mechanism for copper plating of PCB circuit boards includes a movable plate and a mating plate. The movable plate has a mating plate on one side. The movable plate has two symmetrical mounting slots. Two symmetrical guide rails are provided in the mounting slots. A lead screw is provided in the mounting slot. A second knob is fixedly connected to one end of the lead screw. The other end of the lead screw is connected to the inner wall of the mounting slot through a bearing. The lead screw has a movable block. A positioning pin is fixedly connected to the outer wall of one end of the movable block. The mating plate has a groove.

[0006] When using the flip-up clamping mechanism for copper plating of PCB circuit boards in this solution, rotate the second knob according to the position of the PCB board positioning hole to make the moving block move linearly along the guide rail until the positioning pin is aligned with the PCB board positioning hole, and the PCB board positioning hole and positioning pin are engaged. Rotate the first knob to make the bidirectional threaded rod rotate. At this time, the two moving plates move towards each other, and the moving plates fit with the corresponding mating plates. The positioning pin falls into the groove, completing the clamping of the PCB board. Fix the mounting plate in a suitable position above the copper plating tank, and drive the rotating motor to flip the mounting frame as a whole.

[0007] Preferably, the movable block has protruding structures on both sides, and the protruding structures are located inside the guide rail.

[0008] Preferably, both the movable plate and the mating plate are provided with through holes, and a limiting rod is provided in the through holes. One end of the limiting rod is fixedly connected to the outer wall of the fixed frame, and one side of the fixed frame is fixedly connected to the outer wall of the mounting frame. Two movable plates and four mating plates are provided on the limiting rod, and the mating plates are installed on the side corresponding to the positioning pin.

[0009] Preferably, one side of the outer wall of the mating plate is fixedly connected to one end of the spring, the other end of the spring is fixedly connected to one side of the outer wall of the fixing plate, one side of the fixing plate is fixedly connected to the inner wall of the mounting bracket, the fixing plate is provided with a through hole, and a bidirectional threaded rod is provided in the through hole.

[0010] Preferably, the mounting bracket is provided with a bidirectional threaded rod, one end of which is fixedly connected to the first knob, and the other end of which is connected to the inner wall of the mounting bracket through a bearing.

[0011] Preferably, a rotating rod is fixedly connected to one side of the outer wall of the mounting bracket, the rotation center of the rotating rod is fixedly connected to the output shaft of the rotating motor, and the rotating motor is fixedly connected to one side of the outer wall of the mounting plate.

[0012] Compared with existing technologies, the advantages of this utility model are:

[0013] I. This utility model, through an adjustable positioning pin structure that combines a lead screw and a guide rail, can flexibly adjust the position of the positioning holes on different PCB boards to achieve precise positioning. At the same time, the bidirectional threaded rod drives the moving plate to press against the mating plate, and combined with the spring for flexible fixation, which not only ensures the stable clamping of the PCB board, but also avoids damage to the circuit board caused by rigid compression, effectively improving the compatibility and reliability of PCB board positioning and fixing.

[0014] Second, based on the first beneficial effect, once the PCB board is securely clamped, due to accurate positioning and reliable fixation, when the drive motor rotates the mounting bracket to flip, the PCB board will not experience problems such as displacement, loosening, or even falling off. It can safely and stably complete processes that require flipping, such as double-sided copper plating, which greatly improves the efficiency and quality of copper plating processing.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Example 1

[0028] Please see Figures 1-5 As shown, this embodiment is a flip-up clamping mechanism for copper plating of PCB circuit boards, including a movable plate 9 and a mating plate 11. The movable plate 9 has a mating plate 11 on one side. The movable plate 9 has two symmetrical mounting slots. Two symmetrical guide rails 14 are provided in the mounting slots. A lead screw 16 is provided in the mounting slot. A second knob 15 is fixedly connected to one end of the lead screw 16. The other end of the lead screw 16 is connected to the inner wall of the mounting slot through a bearing. The lead screw 16 has a movable block 13. A positioning pin 12 is fixedly connected to the outer wall of one end of the movable block 13. The mating plate 11 has a groove 17. In use, rotating the second knob 15 can rotate the lead screw 16. The rotation of the lead screw 16 can drive the movable block 13 to move along the axial direction of the lead screw 16, thereby adjusting the position of the positioning pin 12 on the movable block 13 to adapt to the positioning holes on different PCB boards.

[0029] Example 2

[0030] Please see Figures 1-5 As shown, this embodiment, based on embodiment 1, further includes: protruding structures on both sides of the moving block 13, the protruding structures being located within the guide rail 14. During use, the protruding structures move linearly along the trajectory within the guide rail 14 to prevent the moving block 13 from deviating during movement and to ensure that the moving block 13 moves only along the axial direction of the lead screw 16.

[0031] Both the movable plate 9 and the mating plate 11 are provided with through holes, and a limiting rod 8 is provided in the through holes. One end of the limiting rod 8 is fixedly connected to the outer wall of the fixed frame 7, and one side of the fixed frame 7 is fixedly connected to the outer wall of the mounting frame 4. The limiting rod 8 is provided with two movable plates 9 and four mating plates 11. The mating plates 11 are installed on one side of the positioning pin 12. In use, each movable plate 9 is provided with two symmetrical positioning pins 12, and each positioning pin 12 is provided with a mating plate 11 on one side. When the bidirectional threaded rod 6 rotates, the limiting rod 8 restricts the rotational offset of the movable plate 9, ensuring that the movable plate 9 moves only along the axial direction of the bidirectional threaded rod 6, and at the same time restricts the mating plate 11 to move only along the axial direction of the limiting rod 8, ensuring that the positioning pin 12 can accurately fall into the groove 17.

[0032] One side of the outer wall of the mating plate 11 is fixedly connected to one end of the spring 10, and the other end of the spring 10 is fixedly connected to one side of the outer wall of the fixing plate 18. One side of the fixing plate 18 is fixedly connected to the inner wall of the mounting bracket 4. The fixing plate 18 is provided with a through hole, and a bidirectional threaded rod 6 is provided in the through hole. In use, the moving plate 9 and the mating plate 11 are pressed together to fix the PCB circuit board. During the pressing process, the spring 10 contracts to store energy and flexibly presses and fixes the PCB circuit board, reducing damage to the PCB circuit board.

[0033] The mounting bracket 4 is equipped with a bidirectional threaded rod 6. One end of the bidirectional threaded rod 6 is fixedly connected to the first knob 3, and the other end of the bidirectional threaded rod 6 is connected to the inner wall of the mounting bracket 4 through a bearing. In use, rotating the first knob 3 causes the bidirectional threaded rod 6 to rotate. The threads at the upper and lower ends of the bidirectional threaded rod 6 are opposite, causing the two moving plates 9 to move towards or away from each other at the same time. When moving towards each other, the moving plates 9 are close to the mating plate 11 to clamp the PCB circuit board. When moving away from each other, the moving plates 9 are away from the mating plate 11 to unload the PCB circuit board.

[0034] A rotating rod 2 is fixedly connected to one side of the outer wall of the mounting bracket 4. The rotation center of the rotating rod 2 is fixedly connected to the output shaft of the rotating motor 1. The rotating motor 1 is fixedly connected to one side of the outer wall of the mounting plate 5. In use, the rotating motor 1 is driven to rotate the rotating rod 2. The rotation of the rotating rod 2 can drive the mounting bracket 4 to rotate, thereby causing the clamped PCB circuit board to flip.

[0035] Instructions for use: When using this device, rotate the second knob 15 according to the position of the PCB board positioning hole, so that the moving block 13 moves linearly along the guide rail 14 until the positioning pin 12 is aligned with the PCB board positioning hole, and the PCB board positioning hole and positioning pin 12 are engaged. Rotate the first knob 3 to rotate the bidirectional threaded rod 6. At this time, the two moving plates 9 move towards each other and the moving plates 9 fit with the corresponding mating plates 11. The positioning pin 12 falls into the groove 17, completing the clamping of the PCB board. Fix the mounting plate 5 in a suitable position above the copper plating tank, and drive the rotating motor 1 to make the mounting frame 4 rotate as a whole.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
