Description

Technical Field

[0001] This utility model applies to the technical field of product positioning, and in particular relates to a copper busbar laser welding pressure claw structure. Background Technology

[0002] The traditional assembly process for new energy vehicle electronic control products requires multiple steps including screwing, gluing, and testing. The copper busbar connections within these products are gradually being replaced by laser welding, giving rise to a new assembly process – laser welding technology. Laser welding can withstand greater tensile and shear forces, and compared to screw connections, it is better able to withstand the vibrations and impacts of electronic control products under complex operating conditions, reducing the risk of malfunctions due to loose connections. With the rapid development of the new energy industry, the requirements for laser welding technology are becoming increasingly stringent. In the future, laser welding technology will develop towards higher power, higher precision, faster speed, and better intelligent control to meet the ever-increasing performance and quality requirements of new energy electronic control products. During laser welding, the requirements for the copper busbar clamping mechanism are also becoming increasingly stringent. It not only needs to clamp the copper busbar but also needs to blow protective gas and extract fumes during the welding process, which are crucial factors in ensuring the stability of the laser welding process.

[0003] Currently, the main method of laser welding copper busbars in electronic control products is lap welding, where one copper busbar is stacked on top of the other and welded together, with the lower busbar typically being thicker. Most current copper busbar clamping mechanisms are designed as open structures, with separate designs for blowing protective gas and dust extraction. If a simple copper busbar laser welding clamping mechanism could be designed that provides pressure and cushioning for the product while simultaneously enabling gas separation to maintain the stability of the laser-welded copper busbars, the aforementioned problems could be solved. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a copper busbar laser welding claw structure that is simple in structure, can press and buffer the product, and can realize air separation to maintain the stability of laser welding of copper busbars in laser welding products.

[0005] The technical solution adopted by this utility model is as follows: This utility model includes a lifting assembly, a buffer assembly, and a pressure claw assembly. The buffer assembly includes a lifting plate and a connecting plate. The lifting plate is connected to the movable end of the lifting assembly. The lifting plate is connected to the connecting plate through several sets of linear bearings. The pressure claw assembly is disposed at the lower end of the connecting plate. The lifting assembly drives the pressure head end of the pressure claw assembly to cooperate with the pressing end of the copper busbar product on the external welding station.

[0006] Furthermore, a buffer plate is provided between the lifting plate and the connecting plate, and the buffer plate is slidably engaged with the lower end of the linear bearing guide rod through several guide sleeves.

[0007] Furthermore, a plurality of buffer springs are provided between the buffer plate and the connecting plate.

[0008] Furthermore, a pressure sensor is provided at the lower end of the lifting plate, and the pressure sensor cooperates with the upper surface of the buffer plate.

[0009] Furthermore, the pressure claw assembly includes a quick-release head and a product pressure head. The quick-release head is connected to the lower end face of the connecting plate, and the product pressure head is connected to the lower end of the quick-release head by a plurality of quick-release screws.

[0010] Furthermore, the lower end of the product pressure head is provided with a pressure nozzle, the middle of the pressure nozzle is provided with a light-transmitting hole, the product pressure head is provided with a light-transmitting channel, the light-transmitting channel is connected and conductive with the light-transmitting hole, and the external laser equipment cooperates with the welding position of the copper busbar product through the light-transmitting hole.

[0011] Furthermore, the nozzle is provided with an air blowing hole in the middle, and the product pressure head is provided with an air blowing channel on one side. The air blowing channel is connected and communicates with the air blowing hole, and the air blowing hole is matched with the outer surface of the external copper busbar product.

[0012] Furthermore, a suction pipe is provided on one side of the quick-release head, and a suction channel is provided on one side of the light-transmitting channel. The suction channel is connected to the suction pipe.

[0013] The beneficial effects of this utility model are: the pressure claw assembly can achieve simultaneous pressing and welding by combining the pressure head and the laser channel, without the need for multiple components to operate independently. It also has an air blowing hole on one side of the light-transmitting hole, which can be used to separate the pressure head and the product after welding, preventing the product from falling off the welding station due to adhesion. At the same time, it is equipped with a lifting and buffering structure, which can effectively avoid overpressure and damage to the product during the pressing process. The structure is simple and the positioning welding efficiency is higher. Attached Figure Description

[0018] like Figures 1 to 4As shown, in this embodiment, the present invention includes a lifting assembly 1, a buffer assembly 2, and a pressure claw assembly 3. The buffer assembly 2 includes a lifting plate 21 and a connecting plate 22. The lifting plate 21 is connected to the movable end of the lifting assembly 1. The lifting plate 21 is connected to the connecting plate 22 through several sets of linear bearings 23. The pressure claw assembly 3 is disposed at the lower end of the connecting plate 22. The lifting assembly 1 drives the pressure head end of the pressure claw assembly 3 to cooperate with the pressing end of the copper busbar product on the external welding station. Therefore, the pressure claw assembly 3, through the multi-stage connection of the buffer assembly 2 and the movable end of the lifting assembly 1, achieves downward positioning, resulting in a simple structure and high positioning accuracy.

[0019] like Figure 2 As shown, in this embodiment, a buffer plate 24 is provided between the lifting plate 21 and the connecting plate 22. The buffer plate 24 is slidably engaged with the lower end of the guide rod of the linear bearing 23 via several guide sleeves 25. Therefore, the buffer plate 24 can serve as a lifting limit, preventing overpressure.

[0020] like Figure 2 As shown, in this embodiment, a plurality of buffer springs 26 are provided between the buffer plate 24 and the connecting plate 22. Therefore, the buffer springs 26 provide a downward buffering force during the synchronous movement of the buffer plate 24 and a restoring force after the welding operation is completed.

[0021] like Figure 2 As shown, in this embodiment, a pressure sensor 4 is provided at the lower end of the lifting plate 21, and the pressure sensor 4 cooperates with the upper surface of the buffer plate 24. Therefore, the pressure sensor 4 can sense the downward pressure during the pressing process, effectively preventing excessive pressure from damaging the product.

[0022] like Figure 1 and Figure 3 As shown, in this embodiment, the pressure claw assembly 3 includes a quick-release head 31 and a product pressure head 32. The quick-release head 31 is connected to the lower end face of the connecting plate 22, and the product pressure head 32 is connected to the lower end of the quick-release head 31 by a plurality of quick-release screws 33. Therefore, the quick-release head 31 can be adapted to various product pressure heads 32, eliminating the need to replace the entire assembly for different products, resulting in fast changeover speed and strong applicability.

[0023] like Figure 3 and Figure 4As shown, in this embodiment, the lower end of the product pressing head 32 is provided with a pressing nozzle 34, the middle of the pressing nozzle 34 is provided with a light-transmitting hole 35, and the product pressing head 32 is provided with a light-transmitting channel 36. The light-transmitting channel 36 is connected and conductive to the light-transmitting hole 35, and the external laser equipment cooperates with the welding position of the copper busbar product through the light-transmitting hole 35. It can be seen that the light-transmitting hole 35 can directly position the welding position when the pressing nozzle 34 presses the product, which can effectively avoid the situation of inaccurate positioning.

[0024] like Figure 4 As shown, in this embodiment, the nozzle 34 is further provided with an air blowing hole 37 in the middle, and the product pressing head 32 is provided with an air blowing channel 38 on one side. The air blowing channel 38 is connected and conductive to the air blowing hole 37, and the air blowing hole 37 mates with the outer surface of the external copper busbar product. Therefore, after the welding operation is completed, the air blowing hole 37 performs an air blowing operation, causing the nozzle 34 to separate from the product pressing surface, preventing the product from shifting or falling off.

[0025] like Figure 1 and Figure 3 As shown, in this embodiment, a suction pipe 5 is provided on one side of the quick-release head 31, and a suction channel 6 is provided on one side of the light-transmitting channel 36. The suction channel 6 is connected to the suction pipe 5. Therefore, during welding operations, dust and flammable metal particles are generated, and the suction channel 6 collects these impurities before they overflow into the light-transmitting channel 36.

[0026] The working principle of this utility model is as follows: Before starting the equipment, the corresponding product pressure head 32 is replaced according to the type of copper busbar product. After installation, an external robotic arm or motion device drives the lifting component 1 to the upper end of the copper busbar product at the welding station. The lifting component 1 drives the product pressure head 32 to press down and contact the copper busbar product, and achieves downward positioning. After pressing, the external laser equipment performs welding operation on the copper busbar product through the light-transmitting hole 35. After the welding operation is completed, the external air pump is started to blow air through the air blowing hole 37, so that the pressure nozzle 34 is separated from the copper busbar product, all components are reset, the copper busbar product to be welded is replaced, and the above steps are repeated to realize the pressing and positioning of the copper busbar product and the laser welding operation.

[0027] Although the embodiments of this utility model are described with reference to actual solutions, they do not constitute a limitation on the meaning of this utility model. For those skilled in the art, modifications to the implementation schemes and combinations with other schemes based on this specification are obvious.
