Description

Technical Field

[0001] The utility model relates to the technical field of battery pressure detection, in particular to a detection machine for detecting the bearing pressure of a battery module. Background Art

[0002] A battery is a device that converts chemical energy into electrical energy. It contains a cup, tank, or other container, or a portion of a composite container, that contains an electrolyte solution and metal electrodes to generate an electric current. It has two electrodes: a positive electrode and a negative electrode. With technological advancements, batteries generally refer to any small device capable of generating electrical energy. After production, batteries typically undergo pressure testing.

[0003] The existing reference publication number is CN109342200A, a Chinese utility model patent, which discloses a square battery internal load pressure detection device, including pressure detection devices respectively arranged on a vertical frame.

[0004] The testing mechanism and the battery placement mechanism to be tested on the horizontal base are controlled by a rodless cylinder to move the battery placement mechanism to the bottom of the pressure testing mechanism inside the vertical frame. Another cylinder controls the pressure testing mechanism to move downward to press the battery to be tested while injecting gas into the battery. The battery shell is monitored to see if there is any tearing under the set air pressure to complete the test. Compared with the existing technology, it has the following advantages: simple structure, convenient and fast testing, and can quickly and easily test whether the square battery is qualified for the bearing pressure. The shell is easy to take and put, which improves the testing efficiency. It also ensures good sealing performance during the testing process, increases the accuracy of the test results, has low equipment improvement costs, is flexible in application during daily work, and improves work efficiency.

[0005] Based on the search of the above patents and combined with the equipment in the prior art, it was found that battery modules need to be pressure tested after production. Traditional pressure testing devices are relatively single when performing pressure testing on battery modules. They are unable to perform uniform testing on battery modules of different sizes, resulting in different force areas in subsequent testing, causing inaccurate subsequent test data, affecting subsequent use. When performing pressure testing on battery modules, there is no protective structure around the traditional structure, resulting in battery module fragments splashing during subsequent battery module pressure testing, causing subsequent accidental injury to staff. The existence of these problems has affected the use of the device. Summary of the Invention
