Referring to fig. 1, a battery glue injection device comprises an installation plate 1, a charging barrel 2, a moving mechanism and a glue injection needle head.

Referring to fig. 1, the cartridge 2 is fixedly mounted on top of a mounting plate 1. In a preferred embodiment, a stirring paddle for uniformly stirring the glue solution is arranged inside the material cylinder 2, a stirring motor 21 for driving the stirring paddle to rotate is installed at the top of the material cylinder 2, and an output shaft of the stirring motor 21 is fixedly connected with the stirring paddle.

Referring to fig. 1, the moving mechanism includes a first rodless cylinder 31, a second rodless cylinder 32, and a third rodless cylinder 33. The first rodless cylinder 31 and the second rodless cylinder 32 are respectively and fixedly arranged on two sides of the bottom of the mounting plate 1. The first end of the third rodless cylinder 33 is fixedly connected with the outer slide block of the first rodless cylinder 31, and the second end of the third rodless cylinder 33 is fixedly connected with the outer slide block of the second rodless cylinder 32. The first rodless cylinder 31 and the second rodless cylinder 32 drive the glue injection needle to move in the X-axis direction; the third rodless cylinder 33 drives the glue injection needle to move in the Y-axis direction.

Referring to fig. 2 to 5, the glue injection needle includes a feed pipe 41, a needle tube 42 and a liquid extraction pipe 43.
