Description

Technical Field

[0001] This utility model relates to the field of electroplating technology, and in particular to an electroplating fixture for irregularly shaped plates. Background Technology

[0002] Irregularly shaped board electroplating fixtures are specially designed tools primarily used to fix and support irregularly shaped circuit boards for electroplating. These fixtures ensure the stability of the circuit boards during electroplating, preventing processing defects caused by movement or vibration, thereby improving electroplating quality and efficiency.

[0003] A search revealed Chinese Patent Publication No. CN209456603U, which discloses an electroplating fixture for irregularly shaped plates. This fixture allows for the clamping of irregularly shaped workpieces by tilting the clamp, reducing manufacturing costs. It includes a main clamping body that is horizontally arranged in a strip shape. Outer clamping bodies are located on both sides of the main clamping body. Connecting strips extending downwards are fixed to the front ends of both the main and outer clamping bodies, each used to connect to a clamp. The lower end of the outer clamping bodies is hinged to the lower end of the main clamping body. Connecting rings are horizontally arranged on the upper parts of the rear ends of both the main and outer clamping bodies. These connecting rings are connected by hook connectors. The hook connectors include a pair of horizontal hooks and several pairs of angled hooks of different specifications. When the horizontal hooks are attached to the connecting rings on the main and outer clamping bodies, the upper ends of the main and outer clamping bodies are in contact, and they are located on the same plane. When the angled hooks are attached to the connecting rings on the main and outer clamping bodies, the upper end of the outer clamping body tilts outwards. However, in actual use, the above-mentioned device has limitations. The hook has strong limitations. When facing irregularly shaped plates of different sizes, the tilt angle of the clamp is limited, and the distance between them is difficult to adjust, resulting in motion interference and affecting normal clamping. Therefore, an electroplating fixture for irregularly shaped plates is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an electroplating fixture for irregularly shaped plates, which aims to improve the problem of motion interference caused by the limited tilt angle of the clamps and the difficulty in adjusting the distance between them when facing irregularly shaped plates of different sizes in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an electroplating fixture for irregularly shaped plates, comprising a mounting frame and a sliding frame, wherein an extension plate is slidably connected to the inner wall of the sliding frame, a rotating plate is rotatably connected to the bottom of the extension plate, a clamping assembly is provided on the front side of the rotating plate, a take-up drum is fixedly connected to the front side of the sliding frame, a braking component is installed inside the take-up drum, a spring is fixedly connected to the outer wall of the braking component, a winding tape is fixedly connected to one end of the spring, one end of the winding tape passes through the inner wall of the take-up drum and is fixedly connected to the front side of the extension plate, a locking plate is fixedly connected to the right side of the inner wall of the take-up drum, a pressing component is installed at the right end of the braking component passing through the inner wall of the take-up drum, and a mounting mechanism is provided on the front side of the mounting frame.

[0006] The above technical solution works as follows: when encountering an irregularly shaped plate that needs to be clamped, the extension plate is dragged downwards and the tape slides downwards by unlocking the spring. After adjusting to a suitable position to clamp the edge of the irregularly shaped plate, the shape rotation plate works in conjunction with the clamping assembly to clamp the irregularly shaped plate. At the same time, the pressing part is pressed to fix the spring through the braking part, thereby completing the clamping and adjustment of irregularly shaped plates of different sizes and shapes.

[0007] As a further description of the above technical solution:

[0008] The installation mechanism includes an adjusting bolt, the bottom end of which is threaded to the top of the mounting frame. The bottom end of the adjusting bolt passes through the top of the mounting frame and is rotatably connected to a lifting plate. Each of the inner walls of the lifting plate is rotatably connected to a pulley. The front side of the mounting frame has an installation groove, and the bottom of the inner wall of the installation groove is rotatably connected to multiple pulleys. A connecting plate is fixedly connected to the rear side of the sliding frame.

[0009] The above technical solution involves connecting the sliding frame to the mounting frame via a connecting plate on the rear side. The connecting plate is inserted into the mounting slot, and the adjusting bolt is rotated to press the lifting plate downwards. Finally, the connecting plate is clamped and limited by pulley one and pulley two. This not only enables the clamping and adjustment of irregularly shaped plates of different sizes, but also allows for the quick installation and disassembly of the fixture.

[0010] As a further description of the above technical solution:

[0011] The clamping assembly includes two mounting plates, the rear sides of which are fixedly connected to the front side of the rotating plate. A clamping plate is rotatably connected between the two mounting plates. A limit post is fixedly connected to the front side of the rotating plate, and a return spring is fixedly connected to the outer wall of the limit post.

[0012] The above technical solution involves the clamping plate clamping the edge of the irregular plate by the mutual contact between the clamping plate and the rotating plate under the return spring.

[0013] As a further description of the above technical solution:

[0014] A rubber pad is fixedly connected to the front side of the clamping plate, and the front end of the reset spring is fixedly connected to the rear side of the clamping plate.

[0015] Through the above technical solution, the rubber pad can effectively improve the friction during operation, making it more convenient to press the clamp.

[0016] As a further description of the above technical solution:

[0017] Both the clamping plate and the rotating plate are fixedly connected to a protrusion on their adjacent sides, and an inclined groove is formed on the adjacent side of each of the two protrusions.

[0018] The above technical solution, with its protrusion and inclined groove design, allows it to adhere more firmly to the surface of the irregularly shaped plate, thus preventing slippage.

[0019] As a further description of the above technical solution:

[0020] The front side of the sliding frame is threaded with a reinforcing bolt, and the front side of the mounting frame is fixedly connected with a rubber strip.

[0021] The above technical solution involves rotating the reinforcing bolt backwards after the sliding frame is adjusted, so that the rear end of the reinforcing bolt fits against the surface of the rubber strip, thereby increasing the fixation of the sliding frame.

[0022] As a further description of the above technical solution:

[0023] Handles are fixedly connected to both the left and right sides of the extension plate, and anti-slip sleeves are fixedly connected to the outer walls of both handles.

[0024] The above technical solution allows for better adjustment of the clamp's position through the handle design.

[0025] As a further description of the above technical solution:

[0026] The mounting bracket is fixedly connected to both the upper and lower sides with fixing plates, and bolts are threaded to the front sides of the fixing plates.

[0027] The above technical solution involves mounting the frame onto the equipment surface using a fixing plate and bolts, facilitating subsequent electroplating.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the extension plate and the sliding frame are connected by a winding belt. The other end of the winding belt is connected to a spring. The winding belt is pulled up and down by adjusting the extension plate, which facilitates the adjustment and clamping of the edge position of irregular plates of different sizes. When the pressing part is pressed, the spring can be braked by the braking part. At the same time, the angle of the clamping component can be adjusted by the rotation connection between the rotating plate and the extension plate. After the position of the clamping component is adjusted, the edge of the irregular plate is clamped by the protrusion between the clamping plate and the rotating plate. Under the squeezing action of the return spring, the clamping force is increased, and the edge of the irregular plate is fully clamped.

[0030] 2. In this utility model, the connecting plate is inserted into the mounting groove. At this time, the lifting plate inside the mounting groove is driven to slide up and down by rotating the adjusting bolt. The connecting plate is clamped by pulley one and pulley two. A limit block is set at the rear end of the connecting plate. When clamped, the limit block will engage with the bottom of the inner wall of the mounting groove, thereby achieving the function of limiting. This installation method can install multiple clamps, improving installation efficiency. Attached Figure Description

A rubber pad 16 is fixedly connected to the front side of the clamping plate 13 and the spring 15. The front end of the return spring 15 is fixedly connected to the rear side of the clamping plate 13. A protrusion 17 is fixedly connected to the adjacent side of the clamping plate 13 and the rotating plate 5. An inclined groove 18 is opened on the adjacent side of the two protrusions 17. After the position of the clamping assembly is adjusted, the return spring 15 is squeezed against each other by pressing the top of the clamping plate 13. The edge of the irregular plate is clamped by the protrusion 17 between the clamping plate 13 and the rotating plate 5. The clamping force is increased under the squeezing action of the return spring 15.

[0040] Specifically, the fixture mainly consists of a mounting frame 1 and a sliding frame 3. The inner wall of the sliding frame 3 is designed with a sliding track, allowing the extension plate 4 to slide smoothly up and down on its inner wall. The bottom of the extension plate 4 is connected to the rotating plate 5 via a rotating shaft.

A locking plate 10 is fixedly connected to the right side of the inner wall of the take-up drum 6. The right end of the braking element 9 passes through the inner wall of the take-up drum 6 and is equipped with a pressing element 11. When the operator presses the pressing element 11, the braking element 9 applies a brake to the spring 7, thereby controlling the winding and unwinding of the winding belt 8. Conversely, when the pressing element 11 is pulled out, the winding belt 8 will automatically... The extension plate 4 is retracted into the take-up drum 6, allowing it to slide upwards and adjust the position of the clamping assembly. The rear side of the mounting plate 12 is fixedly connected to the front side of the rotating plate 5. A clamping plate 13 is rotatably connected between the two mounting plates 12. A limit post 14 is fixedly connected to the front side of the rotating plate 5, and a return spring 15 is fixedly connected to the outer wall of the limit post 14. A rubber pad 16 is fixedly connected to the front side of the clamping plate 13 to provide cushioning and protection when clamping irregularly shaped plates. The front end of the return spring 15 is fixedly connected to the rear side of the clamping plate 13 to ensure that the clamping plate 13 is in a stable position. After release, it can automatically return to the initial position; protrusions 17 are fixedly connected to adjacent sides of the clamping plate 13 and the rotating plate 5, and inclined grooves 18 are opened on adjacent sides of the two protrusions 17. When the clamping assembly is adjusted to the appropriate position, the top of the clamping plate 13 is pressed, causing the return springs 15 to squeeze each other. Then, the protrusions 17 between the clamping plate 13 and the rotating plate 5 are used to clamp the edge of the irregular plate. Under the squeezing action of the return springs 15, the clamping force is significantly improved, ensuring the stability and safety of the irregular plate in the electroplating process.

[0041] Reference Figure 1 , Figure 2 and Figure 5The installation mechanism 2 includes an adjusting bolt 201, the bottom end of which is threaded to the top of the mounting frame 1. The bottom end of the adjusting bolt 201 passes through the top of the mounting frame 1 and is rotatably connected to a lifting plate 202. By rotating the adjusting bolt 201, the lifting plate 202 inside the mounting groove 204 is driven to slide up and down. The bottom of the inner wall of the lifting plate 202 is rotatably connected to a pulley 203. The front side of the mounting frame 1 has a mounting groove 204. The bottom of the inner wall of the mounting groove 204 is rotatably connected to multiple pulleys 205. The pulleys 203 and 205 work together to clamp the connecting plate 206. The rear side of the sliding frame 3 is fixedly connected to the connecting plate 206. The rear end of the connecting plate 206 is provided with a limit block. When clamped, the limit block will be stuck at the bottom of the inner wall of the mounting groove 204, thereby achieving the function of limiting. This installation method can install multiple clamps, improving installation efficiency.

[0042] Specifically, the bottom end of the adjusting bolt 201 is connected to the top of the mounting bracket 1. The bottom end of the adjusting bolt 201 penetrates the top structure of the mounting bracket 1 and is rotatably connected to the lifting plate 202. By rotating the adjusting bolt 201, the lifting plate 202 inside the mounting groove 204 can be driven to perform precise up and down sliding operations. The bottom of the inner wall of the lifting plate 202 is evenly rotatably connected to a pulley 203, which plays a key role in the mechanism. The front part of the mounting bracket 1 is specially provided with a mounting groove 204, and the bottom of the inner wall of the mounting groove 204 is also... Multiple pulleys 205 are connected and rotated evenly. The cooperation between pulley 203 and pulley 205 enables the mechanism to effectively clamp the connecting plate 206. The connecting plate 206 is fixedly connected to the rear part of the sliding frame 3, and the rear end of the connecting plate 206 is carefully designed with a limit block. When the connecting plate 206 is clamped, the limit block can engage with the bottom of the inner wall of the mounting groove 204, thereby achieving a precise limiting function. This innovative installation method can not only efficiently install multiple clamps, but also significantly improve the overall installation efficiency.

[0043] Reference Figure 1 , Figure 2 and Figure 5 The front side of the sliding frame 3 is threaded with a reinforcing bolt 19, the front side of the mounting frame 1 is fixedly connected with a rubber strip 20, the left and right sides of the extension plate 4 are fixedly connected with handles 21, the outer walls of the two handles 21 are fixedly connected with anti-slip sleeves 22, the upper and lower sides of the mounting frame 1 are fixedly connected with fixing plates 23, and the front sides of the multiple fixing plates 23 are threaded with bolts 24.

[0044] Specifically, a reinforcing bolt 19 is connected to the front of the sliding frame 3, which can effectively enhance the stability of the sliding frame. Handles 21 are fixedly connected to both sides of the extension plate 4. The handles 21 allow users to easily grip and operate. In order to further improve the comfort and safety during use, an anti-slip sleeve 22 is fixedly connected to the outer wall of each handle 21. The anti-slip sleeve 22 can effectively prevent the hand from slipping and ensure the safety of operation.

[0045] Working principle: First, the extension plate 4 slides up and down on the inner wall of the sliding frame 3. The extension plate 4 and the sliding frame 3 are connected by a winding belt 8. The other end of the winding belt 8 is connected to the spring 7, which facilitates the adjustment and clamping of the edge position of irregular plates of different sizes. When the pressing part 11 is pressed, the spring 7 can be braked by the braking part 9. Conversely, pulling out the pressing part 11 allows the winding belt 8 to be retracted into the drum 6. At the same time, under the rotational connection between the rotating plate 5 and the extension plate 4, the angle of the clamping assembly can be adjusted. After the position of the clamping assembly is adjusted, pressing the top of the clamping plate 13 causes the return springs 15 to squeeze against each other, and the clamping plate 13 and the rotating plate 5 are squeezed against each other. The protrusion 17 clamps the edge of the irregular plate. Under the compression of the return spring 15, the clamping force is increased, achieving full clamping of the edge of the irregular plate and improving the clamping firmness. Furthermore, the connecting plate 206 is inserted into the mounting groove 204. At this time, the lifting plate 202 inside the mounting groove 204 is driven to slide up and down by rotating the adjusting bolt 201. The connecting plate 206 is clamped by the pulley 1 203 and the pulley 205. The rear end of the connecting plate 206 is provided with a limit block. When clamped, the limit block will engage with the bottom of the inner wall of the mounting groove 204, thereby achieving the limiting function. This installation method can install multiple clamps, improving installation efficiency.
