The embodiment of the present application discloses a battery manufacturing method and system based on negative pressure components. The negative pressure assembly includes a negative pressure cup, a negative pressure nozzle and a normally closed automatic control valve; the automatic control valve includes a negative pressure joint and a control part; the method includes: using the negative pressure suction of the negative pressure assembly The nozzle crimps the liquid injection port of the battery located in the tray so that the internal space of the battery can be communicated with the internal space of the negative pressure assembly to form a closed space; the negative pressure assembly is locked with the tray to form a Negative pressure closes the entire tray; uses air tightness testing equipment to apply negative pressure to the confined space through the negative pressure connector of the negative pressure assembly to perform air tightness detection on the confined space; operates the control part to make the The negative pressure connector communicates with the internal space of the battery. Through the embodiment of the present application, during the battery production process, a closed environment can be formed for the battery whose liquid injection hole is not double-sealed but opened, and the requirement for indoor air in making the battery can be reduced.
Description
technical field [0001] The present application relates to the technical field of batteries, in particular to a method and system for manufacturing batteries based on negative pressure components. Background technique [0002] With the emergence of various electronic devices, the application of square aluminum lithium-ion batteries in various fields is becoming more and more popular. In the process of lithium-ion battery liquid injection and welding sealing nails, the traditional lithium-ion battery process is: liquid injection-nail insertion-standstill, circulation-nail pulling-negative pressure formation-secondary liquid replenishment-welding sealing nails. After the battery is injected, it enters the static process. Although there are nails to block the liquid injection port, in order to prevent the electrolyte in the battery from being affected by the air, it is still necessary to keep the indoor air dry and pure; after the static is completed, the battery is in the proce...
