Closed cavity for injecting liquid into button cell

Abstract

The invention relates to a closed cavity for injecting liquid into a button cell, the closed cavity comprises a servo motor, a hollow rotating platform, a liquid injection valve assembly, a cleaning one-way valve, a liquid injection cavity and a cleaning cavity, one side of the servo motor is connected with the hollow rotating platform, and a fixed platform is fixedly arranged below the hollow rotating platform; the liquid injection valve assembly and the cleaning one-way valve are fixedly arranged on one side of the fixed platform, the hollow rotating platform is connected with a rotating shaft, a rotating fixing frame is fixedly arranged on the rotating shaft, the liquid injection cavity and the cleaning cavity are formed in the two sides of the rotating fixing frame in an up-down movingmode, and a liquid injection receiving table is movably arranged below the liquid injection cavity. The liquid injection cavity and the cleaning cavity are separated and work at the same time, the battery liquid injection efficiency is improved, the liquid injection cavity and the cleaning cavity are made of tempered glass, the situation in the cavities can be conveniently observed, and after theliquid injection machine finishes liquid injection and stops, the waste liquid receiving funnel can be rotated to the position below the liquid injection valve to prevent liquid drops remaining on aneedle head from dropping to other places of equipment.

Description

technical field [0001] The invention relates to the technical field of battery liquid injection, in particular to a sealed cavity for button battery liquid injection. Background technique [0002] Button battery is also called button battery, which refers to a battery whose shape is like a small button. Generally speaking, the diameter is larger and the thickness is thinner. Button batteries are divided into batteries from the shape, and the corresponding battery classification is cylindrical batteries. , Square battery, shaped battery. Generally speaking, there are two types of button batteries, rechargeable and non-rechargeable. The rechargeable ones include 3.6V rechargeable lithium-ion button batteries (LIR series), 3V rechargeable lithium-ion button batteries (ML or VL series); Charging includes 3V lithium-manganese button cells (CR series) and 1.5V alkaline zinc-manganese button cells (LR and SR series). Button batteries are widely used in various miniature electroni...
