Abstract
Description
Technical Field
[0001] This utility model relates to the field of clamping technology, and in particular to a capacitor welding clamp. Background Technology
[0002] A capacitor is a basic electronic component used to store and release electrical charge. It is usually cylindrical and has leads at one end, including axial leads and radial leads. The welding fixtures used in the production of capacitor products are mainly movable welding fixtures. The fixture is placed on the worktable, and then the capacitor is clamped and installed on the fixture and then welded.
[0003] When a capacitor is clamped, the frictional force between the clamp and the capacitor surface is mainly distributed along the circumference of the capacitor. If a torque is applied around the capacitor axis, the frictional force will generate resistance in the circumference. However, since the distribution of frictional force is continuous, the capacitor may still overcome these resistances and rotate.
[0004] Existing capacitor welding fixtures typically clamp the cylindrical surface of the capacitor, which does not affect the welding of the leads at both ends. However, if the clamping force is large, the cylindrical surface is more prone to plastic deformation and indentation compared to the ends. If the clamping force is small, the capacitor may rotate due to the friction generated by the clamping. Therefore, we propose a capacitor welding fixture to solve this problem. Summary of the Invention
[0005] The purpose of this utility model is to solve the problems mentioned in the background art and to provide a capacitor welding fixture.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A capacitor welding fixture includes a support frame with a V-groove. A capacitor cell is placed in the V-groove. An electric push rod is fixedly installed on the left side of the support frame. A lifting plate is fixedly installed on the top of the electric push rod. Two inclined pressure plates are fixedly installed on the bottom of the lifting plate. A baffle is fixedly installed on the front side of the support frame. A sliding plate is slidably installed in the V-groove. A pressure spring is fixedly connected to the front side of the sliding plate. A push plate is fixedly connected to the front end of the pressure spring. The front side of the push plate movably abuts against the rear end of the capacitor cell.
[0008] Preferably, the front side of the baffle has two square holes, the top of which is open, and the capacitor cell includes two pins, which are movably engaged in the corresponding square holes.
[0009] Preferably, an L-shaped plate is fixedly installed on the rear side of the lifting plate, a vertical groove is provided on the top of the sliding plate, and the bottom of the L-shaped plate and the inner wall of one side of the vertical groove are both set as inclined surfaces. The L-shaped plate and the vertical groove cooperate to drive the sliding plate to move horizontally.
[0010] Preferably, a sliding groove is provided on the bottom inner wall of the V-shaped groove, and a sliding block is fixedly installed on the bottom of both the sliding plate and the push plate, and the sliding block is slidably installed in the sliding groove.
[0011] Preferably, side plate one and side plate two are fixedly installed on the left and right sides of the support frame, respectively. The bottom end of the electric push rod is fixedly connected to the top of side plate one. Wing plates are fixedly installed on both the left and right sides of the lifting plate. The output end of the electric push rod is fixedly connected to the corresponding wing plate.
[0012] Preferably, a guide plate is fixedly installed on the top of the second side plate, and a guide hole is opened on the top of the right wing plate, and the guide plate is slidably installed in the guide hole.
[0013] Preferably, anti-slip pads are provided on both inner walls of the V-groove and the bottom of the pressure plate. The anti-slip pads are made of rubber and have multiple anti-slip grooves. The support frame has multiple mounting holes.
[0014] The beneficial effects of this utility model are as follows:
[0015] 1. By using the combination of pressing spring, push plate and baffle, the capacitor cells are clamped and fixed in the front and back directions, increasing the circumferential friction of the capacitor and preventing the capacitor cells from rotating. By using the combination of pressure plate and V-groove, the capacitor cells are pressed and fixed in the vertical direction, providing more circumferential friction and further preventing the capacitor cells from rotating.
[0016] 2. By setting two square holes on the baffle, the two pins are locked in the square holes on the baffle, thereby restricting the rotation of the capacitor cell and ensuring that the capacitor cell remains in a fixed position during installation and use. Attached Figure Description

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0024] Reference Figure 1-4 A capacitor welding fixture includes a support frame 1, a V-groove 2 on the support frame 1, a capacitor cell 3 placed in the V-groove 2, an electric push rod 4 fixedly installed on the left side of the support frame 1, a lifting plate 5 fixedly installed on the top of the electric push rod 4, two inclined pressure plates 6 fixedly installed on the bottom of the lifting plate 5, a baffle 7 fixedly installed on the front side of the support frame 1, a sliding plate 8 slidably installed on the V-groove 2, a pressure spring 9 fixedly connected to the front side of the sliding plate 8, a push plate 10 fixedly connected to the front end of the pressure spring 9, and the front side of the push plate 10 movably abutting against the rear end of the capacitor cell 3.
[0025] It should be noted that the inner walls on both sides of the V-groove contact the surface of the target, forming two contact surfaces. The friction between these two contact surfaces can effectively prevent the capacitor from rotating. Each contact surface includes multiple contact points, and the friction is more evenly distributed, making it more difficult for the capacitor cells to rotate when subjected to external torque.
[0026] like Figure 1 As shown, two square holes 11 are provided on the front side of the baffle 7. The top of the square holes 11 is open. The capacitor cell 3 includes two pins, which are movably engaged in the corresponding square holes 11. The square holes can restrict the rotation of the capacitor cell and ensure that the capacitor cell remains in a fixed position during installation and use. The square holes can also help the pins of the capacitor cell to be precisely aligned with the pads on the circuit board, ensuring good contact between the pins and the pads during soldering.
[0027] like Figure 2 and Figure 3As shown, an L-shaped plate 12 is fixedly installed on the rear side of the lifting plate 5, and a vertical groove 13 is provided on the top of the sliding plate 8. The bottom of the L-shaped plate 12 and the inner wall of one side of the vertical groove 13 are both set with slopes. The L-shaped plate 12 and the vertical groove 13 cooperate to drive the sliding plate 8 to move horizontally.
[0028] A sliding groove 15 is provided on the bottom inner wall of the V-groove 2. Sliding blocks are fixedly installed on the bottom of both the sliding plate 8 and the push plate 10. The sliding blocks are slidably installed in the sliding groove 15, which plays a role in guiding the movement of the sliding plate and the push plate and preventing the sliding plate and the push plate from deviating during horizontal movement.
[0029] like Figure 1 and Figure 4 As shown, side plate one and side plate two are fixedly installed on the left and right sides of the support frame 1, respectively. The bottom end of the electric push rod 4 is fixedly connected to the top of side plate one. Wing plates 16 are fixedly installed on both the left and right sides of the lifting plate 5. The output end of the electric push rod 4 is fixedly connected to the corresponding wing plate 16.
[0030] A guide plate 17 is fixedly installed on the top of the second side plate. A guide hole is opened on the top of the right wing plate 16. The guide plate 17 is slidably installed in the guide hole. The cooperation between the guide plate and the guide hole guides the vertical movement of the lifting plate and prevents the lifting plate from deviating during movement, which would affect the contact between the pressure plate and the capacitor cell.
[0031] In this embodiment, anti-slip pads are provided on both sides of the inner wall of the V-groove 2 and the bottom of the pressure plate 6. The anti-slip pads are made of rubber and have multiple anti-slip grooves. Multiple mounting holes 14 are provided on the support frame 1.
[0032] The working principle of this utility model is as follows: The capacitor cell is placed in the V-shaped groove, with the front side of the capacitor cell abutting against the baffle plate and the two leads being locked in the square holes on the baffle plate. The rear side of the capacitor cell abuts against the push plate. The electric push rod is activated, thereby driving the lifting plate, L-shaped plate and pressure plate to move downward synchronously. During the descent of the lifting plate, firstly, the bottom of the L-shaped plate slides downward along the slope of the vertical groove, thereby squeezing the sliding plate to move forward and compressing the compression spring. Through the cooperation of the compression spring, push plate and baffle plate, the capacitor cell is clamped and fixed in the front-back direction, increasing the circumferential friction of the capacitor and preventing the capacitor cell from rotating. Then, the pressure plate abuts against the outer side of the capacitor cell, providing more circumferential friction and further preventing the capacitor cell from rotating.
[0033] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.

This utility model is limited only by the claims and their full scope and equivalents.
