Technical Field
[0001] The utility model belongs to the technical field of battery shells, in particular to a battery shell welding device. Background Art
[0002] The battery case refers to the container or shell on the outside of the battery, usually made of metal or other suitable materials, which is used to wrap and protect the electrochemical components inside the battery. The main function of the battery case is to provide structural support, protect the internal components of the battery from the external environment, and ensure the normal operation and safety of the battery.
[0003] The battery shell usually includes a shell and an upper cover. The battery is placed in the shell and buckled with the upper cover. The upper cover and the shell need to be welded together. The commonly used welding method is generally to use an ultrasonic welding device for welding. However, since the size of the current welding device is generally fixed, and the length of the battery shell is usually larger than the welding device, only part of the position can be welded at one time during welding, and then the operator manually moves the battery shell to continue welding. This not only has low welding efficiency, but also may cause hand injuries to the operator. For this reason, we propose a battery shell welding device. Utility Model Content
[0004] In order to solve the problem that the size of the current welding instrument is generally fixed, while the length of the battery shell is usually larger than the welding instrument, and only part of the position can be welded at a time during welding, and then the operator manually moves the battery shell to continue welding, which not only has low welding efficiency but also may cause hand injuries to the operator, the utility model provides the following technical solutions: a battery shell welding device, comprising a base, a workbench is installed on the base, a welding instrument is arranged above the workbench, a column is connected between the welding instrument and the workbench, a clamping and pushing mechanism is installed on the workbench, the clamping and pushing mechanism comprises a mounting frame, the bottom of the mounting frame is threadedly mounted on one end of the upper wall of the workbench, the top of the mounting frame is threadedly mounted with a double-column cylinder, the telescopic direction of the double-column cylinder is parallel to the workbench, the telescopic end of the double-column cylinder is threadedly mounted with a clamping assembly, the clamping opening of the clamping assembly faces the other end of the workbench, and the clamping opening of the clamping assembly can clamp the shell.
[0005] Preferably, the clamping assembly includes a cross bar, which is fixedly connected to the telescopic end of the double-column cylinder, and clamps are slidably inserted at both ends of the cross bar. The two clamps can be close to each other to clamp the shell, and a spring is fixedly connected between the two clamps. The spring is arranged in the cross bar, and the two clamps can move away from each other. The spring is stretched to prevent the two clamps from moving away from each other.
[0006] Preferably, there are two clamps, the two clamps are arranged opposite to each other, and buffer pads are arranged on the opposite surfaces of the two clamps. The buffer pads are made of silicone material, and the buffer pads can prevent the clamps from clamping the surface of the shell.
[0007] Preferably, a slide groove is provided on the upper wall of the workbench, and the shell can slide on the slide groove.
[0008] Preferably, an operating panel is provided on the base, and the operating panel is electrically connected to the clamping and pushing mechanism.
[0009] Compared with the prior art, the beneficial effects of the utility model are:
[0010] When working, first manually open the two clamps to both sides, the spring is stretched, and then the upper cover of the battery shell is placed upward on the slide slot, and the side wall of the battery shell is clamped between the two clamps, and the clamps are released. The two clamps are close to each other under the tension of the springs to stably clamp the battery shell, and then the switch and button on the operation panel are used to start the control of the double-column cylinder, so that the double-column cylinder pushes the battery shell to the bottom of the welding instrument, and the head of the welding instrument descends to the top wall of the battery shell for welding. After the welding is successful, the welding instrument is lifted, and the double-column cylinder is controlled again to push the unwelded part of the battery shell to the bottom of the welding instrument, and the welding instrument is controlled to weld. If there are still unwelded parts, continue to control the double-column cylinder to cooperate with the welding instrument for welding. After all welding is completed, manually open the two clamps, take the battery shell out of the two clamps, and move the battery shell by the double-column cylinder, which is convenient for welding battery shells longer than the welding instrument and avoids hand injuries to the operator.
