Description

Technical Field

[0001] This utility model relates to the technical field of copper plating devices, specifically to a circuit board-assisted copper plating device. Background Technology

[0002] In copper plating technology, whether chemical or electrochemical copper plating processes are used, the quality of the circuit board surface has a crucial impact on the plating effect. Chemical copper plating uses a chemical reaction to deposit a thin layer of copper on the surface of the circuit board, such as the hole walls, as a conductive layer for subsequent electroplating. Electrochemical copper plating, on the other hand, uses electrolysis to deposit copper ions on the surface of the circuit board. If scratches occur when handling the circuit board, resulting in scratches, paint peeling, loose or detached components, it will directly affect the quality of the copper plating.

[0003] In existing circuit board placement frame designs, multiple circuit boards are usually arranged closely inside the frame. When it is necessary to remove one of the circuit boards, it is easy for it to come into contact and rub against the adjacent circuit boards. During the removal and placement process, the circuit board may scrape against other circuit boards or the inner wall of the placement frame. This scraping may not only scratch the surface of the circuit board, but also damage the electronic components on the circuit board, affecting its normal electrical performance and reliability, and causing the circuit board to malfunction. Therefore, a circuit board auxiliary copper plating device is needed to meet people's needs. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a circuit board auxiliary copper plating device, including a guide rail, a symmetrical drive seat installed at one end of the guide rail, a limit groove opened in the drive seat, a limit block installed at one end of the limit groove, a placement frame installed at one end of the limit block, and an auxiliary mechanism provided at one end of the placement frame;

[0006] Preferably, the auxiliary mechanism includes multiple sliding grooves formed in the placement frame, multiple rotating wheels installed in the sliding grooves, rotating shafts installed on the sides of two of the rotating wheels, a fixed frame installed at one end of the rotating shaft, an elastic clamp installed in the fixed frame, multiple snap-fit ​​grooves formed at one end of the placement frame, a connecting plate installed at one end of the snap-fit ​​grooves, multiple abutments installed at the bottom of the connecting plate, and a rotating disk threadedly connected to the side of the connecting plate.

[0012] Preferably, the threaded rod is connected to the output end of the drive motor, and the limiting block is threadedly connected to the side of the threaded rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) By setting up rotating wheels and rotating shafts, when the main body of the circuit board needs to be pulled out, the rotating disk drives the connecting plate to move up, thereby driving the abutment to slide in the snap-fit ​​groove, thus removing the obstruction of the rotating wheel. By pulling the fixed frame, multiple rotating wheels can be driven to rotate in the slide groove, the fixed frame can be pulled out, and then the main body of the circuit board can be taken out. The side of the main body of the circuit board is clamped and fixed by elastic clips. The main body of the circuit board can be pulled out in sequence through multiple separated fixed frames, preventing multiple circuit board bodies from scratching each other and improving the applicability of the placement rack.

[0015] (2) This utility model sets up a placement rack and a drive motor, etc. The drive motor is started to drive the threaded rod to rotate, which in turn drives the placement rack to slide in the limiting groove. The limiting block drives the placement rack to move down, immersing multiple circuit board bodies in the treatment pool. After the copper plating is completed, the threaded rod rotates to drive the placement rack to move up. The residual solution on the placement rack is discharged through the leakage tank. By adjusting the threaded rod to move up and down continuously, the residual solution on the circuit board body can be shaken off, reducing the loss of solution. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: Please refer to Figure 1-5This utility model provides a technical solution: a circuit board auxiliary copper plating device, including a guide rail 1, a symmetrical drive seat 3 installed at one end of the guide rail 1, a limit groove 4 opened in the drive seat 3, a limit block 5 installed at one end of the limit groove 4, a placement frame 6 installed at one end of the limit block 5, and an auxiliary mechanism 2 provided at one end of the placement frame 6; the auxiliary mechanism 2 includes multiple sliding grooves 21 opened in the placement frame 6, multiple rotating wheels 22 installed in the sliding grooves 21, a rotating shaft 23 installed on the side of two rotating wheels 22, a fixing frame 24 installed at one end of the rotating shaft 23, an elastic clamp 25 installed in the fixing frame 24, multiple snap-fit ​​grooves 26 opened at one end of the placement frame 6, a connecting plate 27 installed at one end of the snap-fit ​​groove 26, multiple abutments 28 installed at the bottom of the connecting plate 27, a rotating disk 29 threadedly connected to the side of the connecting plate 27, a processing pool 9 provided at the bottom of the guide rail 1, a circuit board body 10 installed at one end of the two fixing frames 24, and multiple... A leakage tank 11 is provided. The bottom of the placement rack 6 has symmetrical clearance openings 12. The rotating wheel 22 is rotatably installed in the slide groove 21. Two rotating shafts 23 are installed at one end of the fixed frame 24. The snap-fit ​​groove 26 is connected to the slide groove 21. One end of the abutment block 28 abuts against one end of the rotating wheel 22. When it is necessary to remove the circuit board body 10, the connecting plate 27 is moved by rotating one end of the rotating disk 29. The abutment block 28 slides in the snap-fit ​​groove 26. One end of the abutment block 28 separates from the rotating wheel 22 and removes the limit on the rotating wheel 22. At this time, the circuit board body 10 can be pulled to drive the fixed frame 24 to slide in the slide groove 21. The rotating wheel 22 rotates in the slide groove 21. After the fixed frame 24 is completely pulled out, the circuit board body 10 can be removed. The fixed frame 24 makes it easy for operators to disassemble and assemble the circuit board body 10. The circuit board body 10 is disassembled and assembled smoothly. Moreover, the distance between multiple circuit board bodies 10 is large, and there will be no scratching. This improves the applicability of the placement rack 6.

[0024] Example 2: As Figure 2-4As shown, a drive motor 7 is installed at one end of the drive base 3, and a threaded rod 8 is installed at the other end of the drive motor 7. The threaded rod 8 is connected to the output end of the drive motor 7. The limit block 5 is threadedly connected to the side of the threaded rod 8. When copper plating is required, the drive base 3 is moved to the top of the processing pool 9 via the guide rail 1. The two ends of the circuit board body 10 are inserted through the fixing frame 24. The side of the circuit board body 10 is pressed against the two ends of the elastic clamp 25. The elasticity of the elastic clamp 25 fixes the circuit board body 10 in the fixing frame 24. By using multiple circuits... The board body 10 is mounted on the placement rack 6. The drive motor 7 is started to drive the threaded rod 8 to rotate, which in turn drives the two limit blocks 5 to slide in the limit groove 4. The limit blocks 5 drive the placement rack 6 to move downward, so that multiple circuit board bodies 10 are lowered into the treatment pool 9 for immersion. After copper plating is completed, the threaded rod 8 rotates in the opposite direction to drive the placement rack 6 to rise. The solution on the placement rack 6 falls into the treatment pool 9 through the leakage tank 11. The threaded rod 8 can be continuously rotated to drive the placement rack 6 to move up and down, so as to shake off the residual solution on the circuit board bodies 10. The other features are the same as in Example 1.

[0025] The working principle is as follows: When copper plating is required, the guide rail 1 drives the drive seat 3 to move directly above the treatment tank 9. The two ends of the circuit board body 10 are inserted through the fixing frame 24, and the sides of the circuit board body 10 are pressed against the two ends of the elastic clamps 25. The elasticity of the elastic clamps 25 fixes the circuit board body 10 within the fixing frame 24. Multiple circuit board bodies 10 are mounted on the placement rack 6. The drive motor 7 is started to rotate the threaded rod 8, which in turn drives the two limiting blocks 5 to slide within the limiting groove 4. The limiting blocks 5 drive the placement rack 6 downwards, lowering the multiple circuit board bodies 10 into the treatment tank 9 for immersion. After copper plating is completed, the threaded rod 8 rotates in the opposite direction, causing the placement rack 6 to rise. The solution on the placement rack 6 falls into the treatment tank 9 through the leakage trough 11. The continuous rotation of the threaded rod 8 drives the placement rack 6 to move up and down, shaking off the residual solution on the circuit board body 10. When it is necessary to remove the circuit board body 10, the connecting plate 27 is moved by rotating one end of the rotating disk 29. The abutment 28 slides in the locking groove 26. One end of the abutment 28 separates from the rotating wheel 22, canceling the limitation on the rotating wheel 22. At this time, the circuit board body 10 can be pulled to drive the fixing frame 24 to slide in the slide groove 21. The rotating wheel 22 rotates in the slide groove 21. After the fixing frame 24 is completely pulled out, the circuit board body 10 can be removed. The fixing frame 24 makes it easy for operators to disassemble and assemble the circuit board body 10, making the disassembly and assembly of the circuit board body 10 stable. Moreover, the distance between multiple circuit board bodies 10 is large, so there will be no scratching, which improves the applicability of the placement rack 6.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
