TECHNICAL FIELD

[0001] The utility model relates to battery pack production technical field especially relates to a pressure detection device for battery pack production extrusion. BACKGROUND

[0002] In the production process of battery pack, pressure detection is an important step to ensure its mechanical strength and safety performance. The traditional pressure detection method usually involves applying single direction pressure test to battery pack. In order to comprehensively evaluate the pressure resistance of battery pack, it needs to be tested in multiple directions. At present, two ways are generally used in the industry to achieve this purpose: one is to rely on manual intervention to change the surface, that is, when the pressure test in one direction is completed, the operator manually turns over or repositions the battery pack to prepare for the next direction test. The other is to use an automatic clamping system to complete the surface changing process, reducing the influence of human factors.

[0003] However, both methods have certain limitations. For manual surface changing, not only is it inefficient, but it also introduces human error, increasing the risk and cost of operation. For the existing automatic clamping surface changing scheme, although it can improve the level of automation and the consistency of testing, most automatic clamping structures have fixed strokes and cannot flexibly adapt to battery packs of different sizes. Since battery packs may have significant differences in size, this fixed clamping structure cannot effectively adapt to various types of battery packs, affecting the effectiveness of surface turning and the accuracy of test results.

[0004] In view of the above deficiencies in the prior art, we provide a pressure detection device for battery pack production extrusion. This device can automatically adapt to the size difference of battery packs. After completing the pressure test in one direction, it automatically fits the side of the battery to control its surface turning, ensuring that regardless of the specific size of the battery pack, it can stably and accurately complete the conversion from one surface to another.

The support base 1 is equipped with a splash-proof assembly for preventing the battery pack from exploding and splashing.

[0020] When using the device, the operator places the battery pack to be pressure tested on the placement seat 4, then controls the hydraulic cylinder 3 to extend and drive the lower pressure frame 31 to slide downward. After the lower pressure frame 31 slides downward, it applies pressure to the battery pack for pressure testing. After applying pressure in one direction, the operator controls the hydraulic cylinder 3 to shorten and drive the lower pressure frame 31 to slide upward and separate from the battery pack.
