Description

Technical Field

[0001] The present invention relates to the field of liquid cooling plate production and manufacturing, and particularly to an assembly device for liquid cooling plate welding. Background Art

[0002] For new energy battery cooling plates, high-frequency welding is usually carried out by using flux-cored wires to melt at high temperature for welding aluminum parts. On the one hand, the flux-cored wires improve the fluidity of the molten slag, reduce weld slag spatter, and enhance arc stability, thereby optimizing the welding process. On the other hand, they can improve the high-temperature oxidation resistance and corrosion resistance of the molten metal, enabling the weld seam to have excellent resistance to hot cracks and low-temperature toughness. For the existing accordion tube water-cooling plates, due to the high requirements for the surface quality of the products, there should be no obvious scratches, particles, and pits, so nitrogen protection welding cannot be used, and only induction welding can be used. The product is divided into three main parts: the current collector, the accordion tube, and the welding wire. The welding wire is placed in the current collector, and then the current collector and the accordion tube are assembled together for welding. The surface requirements of the product are high, and the quality is not easy to control. The assembly before welding takes a long time, and the assembly process cannot be monitored. The assembly effect can directly affect the welding result of the product. In mass production, equipment is needed to improve the assembly efficiency and rhythm, and during the assembly process, it is necessary to detect the assembly effect and the cross-sectional size of the accordion tube. Therefore, it is very important to solve the above problems. Summary of the Invention

[0014] Advantages of the present invention: The present invention rotates the square frame by setting a turntable. Two clamping mechanisms are arranged on each side of the square frame to clamp the harmonica tube, and two fixing mechanisms are arranged to position and place the current collector. In this way, one side of the four sides of the square frame is for feeding, one side is for assembly and pressing, one side is for inspection, and one side is for discharging, improving production efficiency. The pressing mechanism and the cross-section inspection mechanism are arranged on the side of the top frame. The pressing mechanism presses down to contact the top end of the harmonica tube to limit its top end. After the fixing mechanism places the current collector, it rises so that the current collector is assembled with the bottom end of the limited harmonica tube. After assembly, the turntable rotates the harmonica tube and the current collector to one side of the cross-section inspection mechanism, and the cross-section inspection mechanism detects the cross-sectional size of the harmonica tube. After detection, the turntable rotates to the other side for discharging. In this way, automatic assembly and inspection are realized, with high efficiency, good effect, small floor area, and suitable for large-scale production. The clamping mechanism of the present invention clamps the harmonica tube through the flexible clamping wheels on both sides of the mounting frame, so that the position of the harmonica tube can be conveniently adjusted. After the position is adjusted, the suction cup adsorbs and fixes the position of the harmonica tube. The fixing mechanism of the present invention drives the welding base to rise and fall through the upward pushing electric cylinder, and the welding base positions and places the current collector through the placement groove. The pressing mechanism of the present invention drives the pressing block to move down through the downward pressing electric cylinder to contact and limit the top end of the harmonica tube. A force sensor is arranged on the downward pressing electric cylinder. During the process of the upward pushing electric cylinder driving the current collector to rise and assemble with the harmonica tube, the force sensor will sense the force received and transmit it to the MES system, and the MES system then starts the turntable to rotate. The cross-section inspection mechanism of the present invention detects the cross-sectional size of the harmonica tube through the cross-section inspection camera, and the detected data is transmitted to the MES system, and the inspection process is illuminated by the lighting lamp 1. The welding inspection mechanism of the present invention detects whether the welding wire is installed through the welding wire inspection camera, and the result is transmitted to the MES system, and the inspection process is illuminated by the lighting lamp 2.
