The embodiment of the invention discloses a battery manufacturing method and system based on a negative pressure assembly. The negative pressure assembly comprises a negative pressure cup, a negativepressure suction nozzle and a normally closed automatic control valve. The automatic control valve comprises a negative pressure joint and a control part. The method comprises the steps that the negative pressure suction nozzle of the negative pressure assembly is connected with a liquid injection port of a battery located in a tray in a pressing mode so that the internal space of the battery canbe communicated with the internal space of the negative pressure assembly, and a closed space is formed; the negative pressure assembly and the tray are locked to form a negative pressure closed traywhole body; negative pressure is applied to the closed space through the negative pressure joint of the negative pressure assembly by using air tightness detection equipment so as to carry out air tightness detection on the closed space; and the control part is operated to communicate the negative pressure joint with the internal space of the battery. According to the embodiment of the invention,a closed environment can be formed for the battery of which the liquid injection hole is not subjected to secondary sealing and which is opened in the battery production process, so that the requirement of manufacturing the battery on indoor air is 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...
