Description

Technical Field

[0001] The utility model relates to the technical field of battery pack shell welding, in particular to a welding tool for a battery pack shell of a new energy vehicle. Background Art

[0002] At present, automobile technology is undergoing major technological changes such as fuel diversification and power electrification. Electric vehicles with high efficiency, energy saving, low emissions or zero emissions are the inevitable choice to solve the environmental crisis and the oil crisis. Therefore, they are highly valued by countries around the world. The biggest bottleneck in the development of new energy vehicles is the on-board power battery. The life and safety of the power battery play a vital role in the performance of new energy vehicles. The shell of the power battery is a vital component of the power battery and plays a role in packaging.

[0003] Publication number: CN215546121U provides a battery shell welding machine, which relates to the field of battery shell welding technology, and aims to solve the problem that the existing battery shell welding method has a long welding cycle, low welding accuracy, and cannot meet the needs of large-scale welding work. It includes a workbench, a guide rail, a battery shell fixing device, a battery shell to be welded, a welding fixture, and a welding device. The guide rail is installed on the workbench, the battery shell fixing device is installed on the guide rail, the welding fixture is installed above the workbench, and the welding device is installed on the welding fixture. The welding device can be adjusted on the welding fixture to increase the welding range of the welding device and improve the versatility of the entire welding machine. The overall structure of the battery shell welding machine is simple, the design is compact, and it is easy for the staff to install and maintain. The overall structure has good stability and is not easy to damage, which reduces the maintenance cost of the enterprise and realizes semi-automatic production and processing.

[0004] The applicant found that there are some deficiencies in use: when welding, after welding, the welded shell needs to be taken off the work board and put aside, and then the shell to be welded needs to be placed on the work board. Only after that can welding continue. This takes a certain amount of time, which affects the welding efficiency. In addition, the staff member holds the driving handle to push the work board to move the shell. The staff member's arm is under the welding device, which is prone to accidents and is not safe enough.

[0005] Therefore, the utility model designs a welding tool for a battery pack shell of a new energy vehicle to solve the problems existing in the prior art. Utility Model Content

By adjusting the front, back, left and right positions of the welding equipment, the staff does not need to manually move the position of the shell, which is more labor-saving, and the staff arms do not need to be under the welding equipment, thereby improving safety.

[0009] Preferably, the clamping mechanism includes a long groove, which is opened on the top of the placing plate, and a positive and negative threaded screw rod rotatably installed with the placing plate is provided in the long groove, and wire blocks are installed on both sides of the outer walls of the positive and negative threaded screw rods through threaded sliding, and a clamping plate is installed on the top of the wire block through a support rod. The positive and negative threaded screw rods are rotated to make the two wire blocks approach each other, and the two clamping plates are brought close to each other through the support rod, so that the shell can be clamped and fixed, which can improve the stability of the shell during welding and avoid welding deviation.

[0010] Preferably, a hand wheel is installed on one side of the forward and reverse threaded rod, and the hand wheel facilitates the staff to rotate the forward and reverse threaded rod.

[0011] Preferably, the switching mechanism includes a main shaft, which is rotatably installed in the middle of the workbench, and the top of the main shaft is connected to a connecting block, and the two sides of the connecting block are respectively connected to two placement disks, and the bottom of the main shaft is connected to the output end of a servo motor. The servo motor drives the main shaft to rotate 180 degrees, and the two placement disks can be switched. The shell to be welded is turned to the bottom of the welding equipment, and the already welded one is turned to the side of the staff. During the welding process, the staff can replace the shell, and welding and replacement are carried out simultaneously, which can improve the welding efficiency.

[0012] Preferably, rollers which are rotatably connected to the workbench are provided on both sides of the bottom of the connecting block, and the connecting block rotates to drive the rollers to roll on the top of the workbench, thereby reducing the rotation friction of the connecting block.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model is provided with two placement plates and a switching mechanism. The shells to be welded are placed on the two placement plates. When one shell is welded, the servo motor drives the main shaft to rotate 180 degrees, so that the connecting block drives the two placement plates to rotate 180 degrees, and the shell to be welded is transferred to the bottom of the welding equipment for further welding, while the welded shell is transferred to the side of the staff, who replace it. The welding and replacement are carried out simultaneously, thereby improving the welding efficiency;

[0015] 2. The utility model sets an adjusting mechanism and a switching mechanism. The adjusting mechanism can drive the welding equipment to move forward, backward, left and right, so that the welding equipment can weld the shell conveniently without the need for the staff to adjust the position of the shell. The switching mechanism can then automatically turn the welded shell to the side of the workbench away from the welding equipment. The staff only needs to stand on the side of the workbench away from the welding equipment to load and unload materials. Since it is away from the welding equipment, it is safer.
