[0002] The tightness of explosion-proof valves and the like of battery top covers has a great impact on the use safety of batteries. In order to ensure the tightness of battery top covers, tightness detection is required during the production process of battery top covers. At present, helium leak detectors are generally used in the market to detect the tightness of battery top covers;

[0003] The patent publication number CN 219416596 U discloses a double-station helium leak detector for battery top covers, including a feeding device arranged on the machine body. The battery top cover is conveyed to the detection device through the feeding device and conveyed out of the detection device through the feeding device.

[0004] When in use, the device requires workers to take the battery top covers that have been detected during feeding, and after taking them, place the battery top covers to be detected in turn inside the feeding device, resulting in low work efficiency and taking a long time for loading and unloading after detection. Therefore, we propose a double-station helium leak detector for battery top covers. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art and propose a double-station helium leak detector for battery top covers.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

On the front inner wall of the fixed frame, a second motor is fixedly installed. The output end of the second motor is fixedly installed with a second lead screw. On the front and rear sides of the outer side of the second lead screw, sliders are threadedly installed. At the four corners of the bottom inner wall of the fixed frame, fixing plates are fixedly installed; a disassembly and assembly component, which is installed on the fixing plate; a lifting component, which is installed on the support frame.

[0008] Preferably, the disassembly and assembly component includes a sliding rod, a force-receiving block, a spring and a clamping block. The sliding rod is slidably installed inside the fixed plate. The force-receiving block is fixedly installed on the outer side of one end of the sliding rod. One end of the spring is fixedly installed on one side of the fixed plate, and the other end of the spring is fixedly installed on one side of the force-receiving block. The clamping block is fixedly installed on the outer side of the other end of the sliding rod.

[0009] By adopting the above technical solution, the disassembly and assembly of the helium leak detection lower mold by the device is more convenient and fast, and the work efficiency is improved.

[0010] Preferably, the lifting component includes a limiting rod and a helium leak detection upper mold. The limiting rod is fixedly installed between the top inner wall and the bottom inner wall of the support frame. The sliding block is slidably installed on the outer side of the limiting rod. The helium leak detection upper mold is fixedly installed at the bottom of the sliding block.

[0011] By adopting the above technical solution, the lifting of the device only needs to be driven by the first motor, so that the energy cost and manufacturing cost are relatively low.

[0012] Preferably, the height of the sliding block is the same as the distance between the bottom inner wall and the top inner wall of the fixed frame. The sides of the sliding block and the force-receiving block are provided with inclined surfaces.

[0013] By adopting the above technical solution, it is difficult for the second lead screw to drive the sliding block to rotate after rotation. After the sliding block slides, it can drive the force-receiving block to slide through the cooperation of the inclined surface, so that the force-receiving block can drive the clamping block to slide into the inside of the connecting block.

[0014] Preferably, sliding grooves are provided on the front and rear sides of the fixed frame, and a sliding groove is provided on one side of the fixed plate. The sliding rod is slidably installed inside the sliding groove.

[0015] By adopting the above technical solution, the sliding groove facilitates the sliding in or out of the helium leak detection lower mold through the pulley, making it more convenient for the staff to load and unload the battery top cover plate inside the helium leak detection lower mold.

[0016] Preferably, a locking groove is provided on one side of the connecting block, and the clamping block fits with the locking groove.

[0017] By adopting the above technical solution, the clamping block can easily lock the connecting block through the locking groove, making the helium leak detection lower mold more stable after being fixed.

[0018] Preferably, a threaded hole is provided at the top of the sliding block, and the first lead screw meshes with the threaded hole.

[0019] By adopting the above technical solution, the first lead screw can drive the sliding block to be stressed through thread fit after rotation.

[0020] Preferably, a limiting groove is formed at the top of the sliding block, and the outer diameter of the limiting rod is the same as the inner diameter of the limiting groove.

[0021] By adopting the above technical solution, the limiting groove facilitates the limiting rod to limit the sliding block, so that the sliding block can only slide after being stressed.

[0022] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0023] (1) For a double-station helium leak detector for battery top covers of the present utility model, after helium leak detection of the battery top cover is completed through the provided disassembly and assembly component, the second motor is controlled to drive the second lead screw to rotate, so that the second lead screw drives the slider to slide, so that the slider does not contact the force-bearing block, so that the spring drives the sliding rod and the clamping block to slide, so that the clamping block slides out from the inside of the connecting block, so that the helium leak detection lower mold slides out through the pulley below, and a new helium leak detection lower mold is slid into the inside of the fixing frame through the pulley, and the connecting block is locked by the clamping block, so that the device can perform loading and unloading during the helium leak detection process, improving the work efficiency;

[0024] (2) For a double-station helium leak detector for battery top covers of the present utility model, after the helium leak detection lower mold is fixed through the provided lifting component, the first motor is controlled to drive the first lead screw to rotate, so that the first lead screw drives the sliding block to be stressed through screw fit. Since the limiting rod limits the sliding block, the sliding block can only drive the helium leak detection upper mold to slide after being stressed, so that the helium leak detection upper mold can be attached to the helium leak detection lower mold and perform helium leak detection on the internal battery top cover.
