When the sealing of the battery pack does not meet the requirements, it will cause dust, moisture or even water leakage in the battery pack
These situations will lead to damage to the battery system, and more serious may lead to safety accidents
[0004] The sealing performance of the battery pack PACK casing (including the battery pack PACK upper cover and the battery pack PACK lower casing) itself is a key factor affecting the sealing of the battery pack, so the leak detection of the battery pack PACK casing is very important, so It is necessary to test the airtightness of the upper cover of the battery pack and the lower case of the battery pack, but at present, few manufacturers test the lower case of the battery pack, and even less special equipment for corresponding detection

The invention discloses a sealing performance testing device and a sealing performance testing method. The sealing performance testing device comprises a jacking device, a fixing frame, a workpiece sealing mold and a workpiece conveying mechanism; the jacking device is provided with a liftable bracket and a driving device for driving the liftable bracket to lift; the fixing frame is arranged abovethe jacking device in a spaced mode; the workpiece sealing mold is adjustably arranged on the fixing frame and can rotate towards the jacking device; the workpiece conveying mechanism can move the workpiece located on the workpiece conveying mechanism to the position between the jacking device and the workpiece sealing mold from the outer side of the jacking device. According to the scheme, the workpiece conveying mechanism is used for positioning and conveying the workpiece, the workpiece and the mold are combined into the cavity in combination with the jacking device, so that an effective implementation device is provided for automatic sealing performance testing, the mold is fixed to the fixing frame in a position-adjustable mode, the mold can be conveniently mounted, convenience is provided for testing, and the equipment assembling difficulty can be reduced favorably.
Description
technical field [0001] The invention relates to the field of battery pack processing equipment, in particular to a sealing test device and a sealing test method thereof. Background technique [0002] With the rapid development of new energy vehicles, battery packs, which are the core components of new energy vehicles, have attracted more and more attention from enterprises. [0003] In the production process of battery packs, the sealing and waterproof performance of battery packs is an important safety requirement, and the protection level requirements of battery packs in certain layout positions are more stringent, such as the battery pack at the bottom, whose sealing level reaches IP67. When the airtightness of the battery pack does not meet the requirements, it will cause dust, moisture or even water leakage in the battery pack. These situations will lead to damage to the battery system, and more serious may lead to safety accidents. [0004] The sealing performance of...
