Description

Technical Field

[0001] The utility model relates to an automatic installation tool for a negative pressure cap of a large cylindrical battery, belonging to the technical field of battery manufacturing. Background Art

[0002] With the rapid development of the lithium battery industry, large cylindrical batteries have their own advantages in terms of economy, safety, recycling value, etc., and thus have an irreplaceable position. Due to its production process, negative pressure formation is required, and the negative pressure cap is affected by the number of times it is used. Therefore, replacing the negative pressure cap is an inevitable problem in battery production. Moreover, due to the increase in the number of batteries on a single tray, higher requirements are also put forward for the automatic replacement of negative pressure caps.

[0003] Conventional negative pressure caps are replaced manually, but because of the large number of caps to be installed, workers need to enter the equipment to install them, which results in labor costs and potential safety hazards. In addition, only one negative pressure cap can be installed at a time. Since the number of negative pressure caps on a single device exceeds 100, the installation time cost is also very high, which will also indirectly affect the operating efficiency of the equipment.

[0009] 2. The external cylinder at the bottom of the base plate pushes up, pushing the external probe to lift up, thereby driving the spring mechanism unit to lift up, and then installing the negative pressure cap upward into the large cylindrical battery at the work station. At this time, the spring is in a compressed state.

[0010] 3. After the negative pressure cap is installed like a large cylindrical battery, the external cylinder descends, and the spring of the spring mechanism unit pushes the spring mechanism unit to reset.
