Description

Technical Field

[0001] This utility model belongs to the technical field of capacitor processing equipment, specifically a welding fixture for capacitors. Background Technology

[0002] In the capacitor manufacturing process, the welding process is a crucial step. Traditional capacitor welding methods often require manual positioning and clamping of the capacitor. This method is not only inefficient, but also difficult to guarantee consistent welding quality due to variations in human operation. Furthermore, manual clamping of capacitors can easily damage them due to improper force control, affecting their performance and lifespan.

[0003] To improve the efficiency and quality of capacitor welding, various welding fixtures have been developed. However, some existing welding fixtures suffer from problems such as complex structure and inconvenient adjustment. For example, some fixtures cannot be flexibly adjusted to accommodate capacitors of different specifications, limiting their applicability; others experience insufficient smooth sliding between components during operation, resulting in poor overall stability and reliability. Therefore, developing a welding fixture that is simple in structure, easy to adjust, and adaptable to various capacitor welding needs is of significant practical importance. Utility Model Content

By rotating the adjustment handle, the adjustment screw can be driven to rotate, thereby causing the clamping plate to move along the height direction of the movable plate.

[0012] As a preferred embodiment, an elastic buffer layer is provided on the inner wall of the clamping groove. The elastic buffer layer is used to buffer the capacitor when clamping it, so as to avoid damaging the capacitor.

[0013] As a preferred embodiment, a lubricating layer is provided at the sliding connection between the movable plate and the worktable, and between the clamping plate and the movable plate. The lubricating layer is used to reduce sliding friction and make sliding smoother.

[0014] As a preferred embodiment, the telescopic rod is an electric telescopic rod, which can achieve telescopic movement through electric drive, thereby precisely controlling the movement of the movable plate.

[0015] As a preferred embodiment, the adjustment handle is provided with anti-slip texture, which is used to increase the friction when gripping, making it easier for the operator to turn the adjustment handle.

[0016] As a preferred embodiment, the bottom of the workbench is provided with support feet for supporting the workbench, and the bottom of the support feet is provided with anti-slip pads to prevent the workbench from sliding during operation.

[0017] As a preferred embodiment, the clamping grooves on the clamping plate are arranged at equal intervals, and the size of the clamping grooves is designed according to the different specifications of capacitors to meet the welding requirements of various capacitors.

[0018] Beneficial effects:

[0019] I. Significantly Improved Welding Efficiency: This welding fixture, through the coordinated operation of the power and adjustment components, greatly shortens the positioning and adjustment time before capacitor welding. The electric telescopic rod, as the core of the power component, can quickly and accurately drive the movable plate to move along the width of the worktable, increasing speed several times compared to manual movement. The adjustment screw and handle design in the adjustment component allows operators to quickly adjust the clamping plate height, conveniently and quickly positioning the capacitor to the optimal welding position. Simultaneously, multiple clamping slots arranged at equal intervals on the clamping plate can hold multiple capacitors at once, enabling batch welding and significantly increasing welding output per unit time, thus significantly improving overall welding efficiency.

[0020] II. Effectively Ensuring Welding Quality: Stable and precise positioning is key to ensuring welding quality. The high-precision sliding connections between the movable plate and the worktable, and between the clamping plate and the movable plate, along with the cooperation between the guide groove and the guide block (or guide wheel), ensure that the capacitor maintains a stable position throughout the welding process, avoiding welding defects caused by positional misalignment. The elastic buffer layer on the inner wall of the clamping groove not only securely holds the capacitor but also prevents damage during clamping, ensuring that the capacitor's performance is not affected. This effectively improves welding quality and reduces the product defect rate.

[0021] III. Enhanced Tooling Applicability: Considering the diversity of capacitor specifications on the market, this tooling is highly flexible in design. The clamping slot dimensions are specifically designed for different capacitor specifications, ensuring a suitable clamping slot for both small surface-mount capacitors and large electrolytic capacitors, greatly expanding the tooling's applicability.

[0022] IV. Reduced Tooling Maintenance Costs: The simple and clear structural design is a major advantage of this welding fixture. Compared to traditional welding fixtures with complex structures, this utility model has a reduced number of components and a simple and easy-to-understand connection method. This not only reduces the manufacturing cost of the fixture but also enables quick location of problematic components for efficient repair or replacement during routine maintenance and troubleshooting. For example, when a component malfunctions, the clear connections between the components allow maintenance personnel to quickly disassemble and replace it, greatly shortening downtime and reducing production losses caused by equipment failure, while also lowering long-term maintenance costs.

[0023] V. Enhanced Ease of Operation: The anti-slip textured design on the adjustment handle fully considers the operator's experience. During actual operation, operators can more easily and stably rotate the adjustment handle to achieve precise control of the clamp height. The support feet and anti-slip pads at the bottom of the workbench ensure the stability of the fixture during operation, eliminating concerns about fixture slippage and allowing operators to focus on welding work, further enhancing ease of operation and comfort.

[0031] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figure 1-3 The detailed description of the embodiments will clearly demonstrate this. All structural details mentioned in the following embodiments are based on the accompanying drawings.

[0032] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0033] Example 1: A welding fixture for capacitors mainly consists of a worktable 1, a movable plate 11, a clamping plate 12, a power assembly 14, and an adjustment assembly 15. The worktable 1 serves as the basic support structure of the entire fixture, providing a stable platform for the installation and operation of other components. The movable plate 11 is slidably connected along the width direction of the worktable 1, while the clamping plate 12 is slidably connected along the height direction of the movable plate 11. Multiple clamping grooves 13 are evenly distributed on the clamping plate 12 for securely holding the capacitor. Through the coordinated sliding of the movable plate 11 and the clamping plate 12, the position of the capacitor can be flexibly adjusted to meet the requirements of different welding processes.

[0034] Power Component 14: The power component 14 is mounted on the worktable 1, and its core function is to drive the movable plate 11 to make precise extension or retraction movements along the width direction of the worktable 1. The surface of the worktable 1 has a sliding groove 2 adapted to the movable plate 11. A guide groove 21 is machined on the inner wall of the sliding groove 2. A guide block 22 or guide wheel is correspondingly provided at the bottom of the movable plate 11. The two work together to effectively ensure the stability and straightness of the movable plate 11 during sliding, avoiding deviation or jamming. The power component 14 specifically includes a telescopic rod 141 fixedly installed in the sliding groove 2. The extended end of the telescopic rod 141 is firmly connected to the movable plate 11. When the telescopic rod 141 is activated, its extension and retraction movements can precisely control the movement of the movable plate 11, ensuring that the capacitor is accurately delivered to the welding position. In a preferred embodiment, the telescopic rod 141 is an electric telescopic rod 141. With the help of electricity, the electric telescopic rod 141 can achieve precise extension and retraction control, greatly improving the accuracy and repeatability of the movement of the movable plate 11, laying the foundation for high-quality welding operations.

[0035] Adjustment Component 15: The adjustment component 15 is mounted on the movable plate 11. Its main function is to drive the clamping plate 12 to move along the height direction of the movable plate 11, thereby achieving precise adjustment of the capacitor's height position. The movable plate 11 has an adjustment groove 23 adapted to the clamping plate 12. The adjustment component 15 includes an adjustment screw 151 rotatably connected to the inner wall of the adjustment groove 23. The adjustment screw 151 is threadedly connected to the clamping plate 12. An adjustment handle 152 is fixedly mounted on one end of the adjustment screw 151. By rotating the adjustment handle 152, the operator can easily drive the adjustment screw 151 to rotate. Due to the characteristics of threaded transmission, the clamping plate 12 will move smoothly along the height direction of the movable plate 11. To facilitate the operator's application of force, the surface of the adjustment handle 152 is designed with anti-slip textures to increase friction during gripping, making the adjustment operation smoother and less strenuous.

[0036] Protection and Adaptability Design: Considering the vulnerability of capacitors to external force during clamping, this invention incorporates an elastic buffer layer on the inner wall of the clamping groove 13. This elastic buffer layer is typically made of soft materials with good cushioning properties, such as rubber or silicone. When the capacitor is placed within the clamping groove 13, the elastic buffer layer effectively absorbs and disperses the clamping force, preventing scratches, deformation, and other damage to the capacitor casing caused by hard compression, thus ensuring that the capacitor's performance remains unaffected. Furthermore, the clamping grooves 13 on the clamping plate 12 are designed with equal spacing, and the dimensions of the clamping grooves 13 are carefully planned to be customized for various capacitor specifications commonly found on the market. This allows the welding fixture to be widely adaptable to a wide range of capacitors, significantly improving its versatility and practicality.

[0037] Lubrication and Support Design: To ensure smooth and unobstructed sliding connections between the movable plate 11 and the worktable 1, and between the clamping plate 12 and the movable plate 11, a lubrication layer is provided at these sliding connections. The lubrication layer is typically achieved by applying lubricating oil or installing self-lubricating bearings, which effectively reduces sliding friction between components, lowers energy loss, and extends the service life of the tooling. Simultaneously, support feet are provided at the bottom of the worktable 1. These feet not only support the worktable 1 but also have anti-slip pads affixed to their bottoms. The anti-slip pads are generally made of high-friction materials such as rubber, effectively preventing the worktable 1 from sliding due to external vibrations or improper operation during operation, ensuring the stability and reliability of the welding tooling during operation.

[0038] When using,

[0039] Tooling installation steps: First, place the workbench 1 on a level and stable workbench 1, ensuring that the anti-slip pads at the bottom of the support feet are in close contact with the workbench surface, providing a stable support foundation for the entire tooling. Next, install the movable plate 11, accurately embedding the guide block 22 or guide wheel at the bottom of the movable plate 11 into the guide groove 21 on the inner side wall of the slide groove 2 of the workbench 1. Gently push the movable plate 11 to check if its sliding within the slide groove 2 is smooth. If there is any jamming, adjust the position of the guide block 22 or guide wheel promptly. Then, install the power assembly 14, fixing the telescopic rod 141 to the pre-set installation position within the slide groove 2, and using bolts or other connectors to firmly connect the extended end of the telescopic rod 141 to the movable plate 11, ensuring the strength and stability of the connection. For the adjustment assembly 15, first install the adjustment screw 151 on the inner wall of the adjustment groove 23 through rotating connecting parts such as bearings to ensure that the adjustment screw 151 can rotate flexibly. Then, connect the clamping plate 12 to the adjustment screw 151 with threads. Finally, install the adjustment handle 152 and check whether the movement of the adjustment screw 151 and the clamping plate 12 is normal when the adjustment handle 152 is rotated.

[0040] Tooling Usage Procedure: Before using the welding tooling, select a suitable clamping slot 13 according to the specific specifications of the capacitor to be welded. Carefully place the capacitor in the selected clamping slot 13; the elastic buffer layer will automatically cushion and protect the capacitor. Then, the operator precisely adjusts the height of the clamping plate 12 according to the welding process requirements by rotating the adjusting handle 152, ensuring the capacitor is at the ideal welding height. After height adjustment, start the power assembly 14. If an electric telescopic rod 141 is used, the moving distance and speed of the movable plate 11 can be set via the control button or the control program on the operation panel. The electric telescopic rod 141 drives the movable plate 11 to move smoothly along the width of the worktable 1, accurately delivering the capacitor to the designated welding position below the welding equipment. During welding, if the capacitor's position requires further fine-tuning, the welding operation can be paused at any time, and the capacitor's position can be precisely adjusted again via the adjusting handle 152 or the control device of the power assembly 14 to ensure welding quality.

[0041] Key points for tooling maintenance: Regular maintenance of welding tooling is crucial for ensuring its long-term stable operation. During routine maintenance, first check the connections between components, such as bolts and nuts, for looseness. If loosening is found, tighten them promptly using tools. Simultaneously, regularly clean debris and dust from the slide groove 2, adjusting groove 23, and all sliding connections to prevent these impurities from entering the sliding parts and affecting the smoothness of the components' movement. For the lubrication layer, replenish lubricating oil or replace self-lubricating bearings at specified intervals or usage cycles to ensure that sliding friction remains at a low level. Furthermore, frequently check the elastic buffer layer for wear, aging, or damage. If a decrease in the buffering performance of the elastic buffer layer is found, replace it immediately to ensure effective protection of the capacitor. For electrical components such as the electric telescopic pole 141, regularly check the electrical connections for security and for any safety hazards such as damaged or short-circuited wires. If any faults are found, repair or replace the corresponding components promptly to ensure the normal operation of the power assembly 14.

It should be understood that the present utility model is not limited to the above embodiments, and various modifications that conform to the concept of the present utility model are within the protection scope of the present utility model.
