Description

Technical Field

[0001] The utility model relates to the technical field of a test fixture, in particular to a foldable test fixture suitable for testing blade batteries in a temperature box. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloys as positive / negative electrode materials and a non-aqueous electrolyte solution. Due to the highly active chemical properties of lithium metal, its processing, storage, and use place very high demands on the environment. With the development of science and technology, lithium batteries have become mainstream. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. In response to the continuous expansion of the lithium battery new energy market, battery models and specifications have also diversified. Currently, due to site layout limitations and production capacity issues, manufacturers need to arrange some blade batteries before lithium battery testing to meet customer expectations and production capacity. In response to this situation, professional technicians from equipment manufacturers are needed to provide solutions and effectively implement them.

[0003] When using a high and low temperature test chamber, considering that a single experiment takes a long time, if multiple lithium batteries are tested sequentially, it will produce a very high time cost, which is not feasible in practice. On the other hand, if multiple lithium batteries under test cannot be raised to the predetermined temperature at the same time, the consistency of the experimental environment cannot be guaranteed, resulting in errors. Therefore, multiple lithium batteries must be tested in each experiment, and the test chamber must be kept closed during the experiment to reduce temperature fluctuations around the tested lithium batteries. The internal space of a small high and low temperature test chamber is small, and the lead holes are also small, so it is impossible to manipulate its interior in an overly complicated way. In order to reduce temperature fluctuations around the lithium batteries to be tested, once the experiment begins, it is necessary to avoid opening the high and low temperature test chamber as much as possible. However, with existing technologies, once the lithium batteries and fixtures under test are placed in the test chamber, they cannot be operated.

[0004] Currently, the probes on the market have complex structures, occupy large spaces, and have poor testing stability in high and low temperature environments; they are not compatible with large battery sizes, have no positioning adjustment function, and the probes are not compatible with large battery pole sizes; the movement of the probe requires tools to operate. Summary of the Invention
