DETAILED DESCRIPTION
[0016] Clearly, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.
[0017] Please refer to Figs. 1-3This utility model provides a technical solution: a photovoltaic circuit breaker component welding and positioning device, including a positioning base plate 1, which is a rectangular plate structure with mounting holes at its four corners. Side plates 2 are symmetrically welded and fixed on both sides of the positioning base plate 1, arranged vertically. A push bar frame 4 is driven by a cylinder 3 on each corresponding side of the side plate 2. The inner end of the cylinder 3 is fixed to the side plate 2 with bolts. The output end of the cylinder 3 is fixedly connected to the middle of the back side of the push bar frame 4. A coupling 6 is symmetrically fixed through the push bar frame 4. A right-angled docking block 7 is connected to the outer end of the coupling 6. Clamping arms 8 are installed between the same group of docking blocks 7. The two ends of the clamping arms 8 are fitted into the interior of the docking blocks 7 and fixed with bolts. Symmetrical arrangements are provided between the back side of the clamping arms 8 and the push bar frame 4. The elastic support 9, the connection between the elastic support 9 and the clamping arm 8 and the push bar 4 can all be fixed by welding. The elastic support 9 can be made of materials suitable for manufacturing elastic elements, such as spring steel or stainless steel, which are alloy materials with excellent elasticity and corrosion resistance. Furthermore, the back side of the clamping arm 8 is fixed with a balance template 10 via a connector. The positioning base plate 1 of this structure provides a stable foundation platform, ensuring the stability of the entire device. The two side plates 2 enhance the rigidity of the overall structure, providing robust support for the positioning components. When the cylinder 3 is driven, it pushes the bar 4 to move precisely horizontally. When the bar 4 moves horizontally, it can drive the clamping arm 8 to the precise position of the component to be welded via the coupling 6 and the docking block 7. The device effectively absorbs vibrations that may occur during welding through the elastic support 9 during the clamping process, reducing component position displacement caused by vibration and ensuring component stability. The balancing template 10 further enhances the stability of the clamping arm 8, ensuring that the component maintains an ideal welding position throughout the welding process, even in the face of external interference such as ambient temperature changes or mechanical vibrations. Therefore, this device solves the problem of component position displacement caused by external factors such as temperature changes, differences in material thermal expansion coefficients, and mechanical vibrations in existing technologies. It avoids uneven weld joints or poor contact, improves welding consistency and precision, and significantly enhances the overall performance and service life of the product. It is particularly suitable for photovoltaic components requiring high precision. In the welding operation of circuit components, a telescopic column 601 is provided at the connection between the coupling 6 and the docking block 7, and a compression spring 602 is sleeved on the outside of the telescopic column 601. This structure of the telescopic column 601 allows the docking block 7 to be finely adjusted within a certain range to accommodate components of different sizes or shapes, ensuring that the clamping arm 8 can be accurately positioned to the required position. At the same time, the compression spring 602 can provide necessary buffering between the docking block 7 and the coupling 6, absorbing and mitigating the impact force caused by mechanical vibration or other external interference, thereby reducing the impact on the positioning accuracy of the components. A pressure sensor 1001, model PX309-100GV, is provided on the middle edge of the top of the clamping arm 8, and a dynamic module 1002 is symmetrically provided on the back side of the balance template 10 through the guide rail groove.The dynamic module 1002 is connected with the pressure sensor 1001 through wires. The pressure sensor 1001 of this structure can monitor the pressure applied to the element during clamping in real time and transmit these data to the dynamic module 1002 through wires. The dynamic module 1002 can move laterally along the guide groove on the back side of the balance template 10 to adjust to the most appropriate position, ensuring optimal support and stability during the entire welding process. The two sides of the push bar 4 are provided with linkage guide rods 5, which are connected to the push bar 4 by welding. The two sides of the side plate 2 are provided with perforations matched with the structure of the linkage guide rod 5. When the cylinder 3 drives the push bar 4 to move laterally, it will simultaneously drive the linkage guide rod 5 to slide smoothly along the perforations on the side plate 2. Through this precise cooperation mechanism, the linkage guide rod 5 not only provides additional guiding support, ensuring the linearity and stability of the movement of the push bar 4, but also effectively reduces the operation error caused by deviation or misalignment, making the entire device more accurate and reliable when performing welding positioning operations, especially in high-precision positioning scenarios such as photovoltaic circuit breaker element welding operations, which can significantly improve welding quality and consistency. The two sides of the bottom of the push bar 4 are welded with guide blocks 401, and the two sides of the top of the positioning bottom plate 1 are provided with guide grooves matched with the structure of the guide blocks 401. When the cylinder 3 drives the push bar 4 to move laterally, the guide blocks 401 can slide smoothly along the guide grooves on the positioning bottom plate 1, further preventing the push bar 4 from deviating or shaking during movement, ensuring higher accuracy and consistency during movement. The inside of the clamping arm 8 is uniformly provided with several heating elements 801, and the outer surface of the clamping arm 8 is bonded with flexible rubber pads. When the clamping arm 8 clamps the element, the heating elements 801 can uniformly provide heat to the clamping area, allowing the welding point to be welded at an appropriate temperature, avoiding welding defects caused by uneven temperature. At the same time, the flexible rubber pads on the outer surface of the clamping arm 8 not only provide good cushioning effect, reducing the mechanical damage to the element during clamping, but also increase the friction, further ensuring the stability of the element during welding.
[0018] Working principle: when using the photovoltaic circuit breaker element welding positioning device, first, the positioning base plate 1 is stably installed on the workbench through the mounting holes in the four corners, then the clamping arms 8 are inserted into the butt blocks 7 and fixed by bolts, ensuring that the clamping arms 8 are correctly installed between the butt blocks 7 of the same group, then the air cylinder 3 on the side plate 2 is started, the air cylinder 3 drives the push bar frame 4 to move horizontally, and the linkage guide rod 5 slides smoothly along the perforated hole on the side plate 2, the horizontal movement of the push bar frame 4 drives the coupling 6 and the butt block 7 to move synchronously, so that the clamping arm 8 is moved to the accurate position of the element to be welded, at this time, the heating element 801 in the clamping arm 8 starts to work, providing heat uniformly to the clamping area, at the same time, the dynamic module 1002 moves horizontally along the guide groove on the back side of the balance template 10 according to the real-time data provided by the pressure sensor 1001, and is adjusted to the most suitable supporting position, when the clamping arm 8 clamps the element, the flexible rubber pad contacts the element, and as the welding process proceeds, the elastic support 9 absorbs the vibration that may be generated during the welding process, ensuring that the element is stable and does not move, thereby completing a series of work.
[0019] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
