beneficial effect

First, the present invention not only has the transplanting function of realizing module welding loading and unloading, but also has the function of blocking the bottom of the copper nozzle of the welding fixture to facilitate cleaning, and the two functions are independent of each other in action and rhythm. There is no mutual interference and conflict.

Second, the pulling type transplanting structure of the present invention realizes loading and unloading by cooperating with the tray module and pulling the tray module to move. Compared with the traditional lifting type transplanting structure with pin hole positioning, the structure is simplified and the coordination efficiency is high. . In addition, in this traction type transplanting structure, the position of the tow bar will not hinder the flow of the tray module on the wire body, which simplifies the transplanting cycle process, and can shorten the transplanting action stroke, which is beneficial to improve the transplanting rhythm of the module. , to improve the efficiency of module welding and loading and unloading.

Detailed ways

The present invention will be further described below in conjunction with specific embodiments. It should be understood that these examples are only used to illustrate the present invention and not to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of the present application.

As shown in FIG. 1, a lithium battery laser welding transplanting and copper nozzle blocking mechanism includes a substrate 1, a transplanting cylinder 2, a guide rail 3, a mobile platform 4, a roller conveyor chain 5, a tow bar 6, and a blocking plate 7. and jacking up the cylinder 8.

The transplanting cylinder 2 and the guide rail 3 are installed vertically and in parallel above the base plate 1 through the bracket, and the moving table 4 is installed across the transplanting cylinder 2 and the guide rail 3 to form a gantry structure. The moving table 4 can be driven by the transplanting cylinder 2 along the Move vertically. A support frame 9 is installed on both sides of the base plate 1 near the transplanting cylinder 2 and the guide rail 3 in the longitudinal direction. The top of the support frame 9 is respectively installed with a roller conveyor chain 5.
