Description

Technical Field

[0001] The utility model relates to the technical field of battery production, and more specifically to a clamp device for producing square batteries. Background Art

[0002] The fixture device for square battery production is a lithium battery constraint fixture that uses a pressure-controlled method to simulate the preload and constraint environment of the lithium battery during the module design process. The lithium battery is squeezed and tested by controlling the telescopic rod to compress the four springs located at the four corners of the support plate. A gravity sensor is installed at the bottom of the lithium battery to facilitate real-time monitoring of the battery force evolution process in the constraint fixture, thereby facilitating the battery to remain stable during welding, assembly and testing.

[0003] The existing square battery production fixture device uses a pressure-controlled method to simulate the preload and constraint environment of the square battery during the module design process in daily use. When the square battery is unqualified, the parameters will be adjusted too much, causing the battery to explode and generate high temperature instantly during the explosion, which will cause safety accidents due to unqualified quality when the operator is using the equipment, thus affecting the operator's use.

[0004] In daily use, the existing square battery production fixture device requires the operator to conduct a large number of square batteries when conducting square battery simulation tests, which results in the operator manually placing the batteries for testing, which greatly affects the operator's testing efficiency and thus affects the operator's user experience.
