Abstract

The invention relates to an electrolyte priming head and belongs to the battery manufacturing field; the electrolyte priming head comprises a tube-shaped cavity and a pin valve; the pin valve is arranged at the top part of the tube-shaped cavity, and a valve port is arranged at the bottom part of the tube-shaped cavity; the valve port is provided with a channel which is communicated with a priming port of the battery; a vacuum-pumping line connecting port and a priming line connecting port are arranged on the tube-shaped cavity; the vacuum-pumping line and the priming line are communicated with the cavity; switches for controlling on and off are arranged on the vacuum-pumping line and the priming line. The pin valve can move up and down corresponding to the tube-shaped cavity, and one end of the pin valve is matched with the valve port. The electrolyte priming head has simple structure and high priming precision, can reduce the volatilization of the electrolyte and improve the battery performance.

Description

technical field [0001] The electrolyte injection head of the invention belongs to the field of battery manufacturing, and in particular relates to an electrolyte injection head used on a liquid injection machine for injecting electrolyte into a battery casing during battery production. Background technique [0002] During the battery production process, it is necessary to fill the battery case with electrolyte, and the amount of electrolyte charged directly affects the performance of the battery. In order to ensure the performance of the battery, it is necessary to strictly control the injection accuracy of the electrolyte. Usually, the injection of the electrolyte is realized through a liquid injection machine, and the liquid injection head of the liquid injection machine, such as the attached figure 1 As shown, it is in the shape of a syringe, its head is sealed and connected to the battery case, and the tail is provided with an electrolyte injection port, a vacuum port an...
