注液机构及注液装置
摘要：
本发明公开了一种注液机构及注液装置，涉及电池制造技术领域。该注液机构，包括注液筒和活塞，注液筒包括相互连通的注液段和泄压段，泄压段的口径大于注液段的口径，注液段用于与待注液电芯连通，活塞设置于注液筒内，并能够于注液段和泄压段内运动，且活塞与注液段密封配合，与泄压段间隙配合。该注液机构及注液装置具有便于泄压，注液稳定，且安全可靠的特点。
摘要（英）：

The invention discloses a liquid injection mechanism and device and relates to the technical field of cell manufacturing. The liquid injection mechanism includes a liquid injection cylinder and a piston, wherein the liquid injection cylinder includes a liquid injection section and a pressure relief section which are communicated with each other, the diameter of the pressure relief section is larger than the diameter of the liquid injection section, the liquid injection section is used for communicating with a to-be-injected cell, the piston is disposed in the liquid injection cylinder and is movable in the liquid injection section and the pressure relief section, and the piston is sealingly matched with the liquid injection section to cooperate with the pressure relief section. The liquidinjection mechanism is advantaged in that the liquid injection mechanism is convenient for pressure relief, is stable for liquid injection and is safe and reliable.
