Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing equipment technology, specifically to an electrolyte filling device. Background Technology

[0002] In the production process of secondary batteries (such as lithium-ion batteries and sodium-ion batteries), the electrolyte acts as a "bridge" for ion transport between the positive and negative electrodes. The quality of its filling process directly determines the core performance of battery energy storage and release, and it is a key link connecting electrode preparation and packaging.

[0003] According to the authorized announcement number CN213340669U, an electrolyte filling device is disclosed, including a base plate, a support fixedly connected to the top of the base plate, a liquid storage tank at the bottom of the support, a delivery pipe at the bottom of the liquid storage tank, a solenoid valve on the outside of the delivery pipe, an outer frame at the top of the base plate, a vertical cylinder at the top of the outer frame, and a clamping assembly inside the outer frame. The clamping assembly includes a first airbag, which is disposed inside the vertical cylinder. The number of first airbags is set to multiple. The electrolyte filling device can pull the second airbag by a first pull rope and a second pull rope, thereby increasing the volume of the second airbag, which is conducive to inflating the second airbag through the air inlet pipe. This device has a novel and compact structure, and can automatically fix the battery when it is placed, thereby facilitating the delivery of electrolyte into the battery and improving the filling efficiency.

[0004] However, the above-mentioned device still has shortcomings. Although a multi-airbag installation method is adopted to improve the efficiency of electrolyte filling, manual handling is still required, which affects the filling efficiency and increases the workload of manual labor. There are also placement and installation risks during the filling process. Utility Model Content
