[0002] With the popularity of electric vehicles, portable electronic devices, etc., lithium batteries have become increasingly important as an efficient energy storage solution. However, the safety of lithium batteries is directly related to the reliability of the products used and the safety of users. The airtightness defects of the shell may cause the battery performance to decline and even cause safety problems. The traditional manual inspection method is inefficient on high-speed production lines and has the risk of missed inspections and inspection errors. It cannot guarantee the qualified rate of battery shell processing.

[0003] Therefore, it is necessary to design a defective product rejection device for battery shell processing to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of the utility model is to provide a defective product rejection device for battery shell processing to ensure the qualified rate of battery shell processing, thereby solving the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A defective product rejection device for battery shell processing comprises a battery shell quality inspection lower die seat, a classification activity cavity is penetrated through the inner center of the battery shell quality inspection lower die seat, an airtightness detection boss is movably installed inside the classification activity cavity through an electric rotating rod, an unqualified material discharge channel and a qualified material discharge channel are fixedly installed on the front and rear sides of the airtightness detection boss respectively, and automatic conveying devices are movably installed at the bottom of the unqualified material discharge channel and the qualified material discharge channel.

[0007] As a preferred solution of the utility model, a vacuum nozzle and a vacuum sensor are fixedly installed on the top surface of the airtightness detection boss, a vacuum pump is fixedly installed inside the airtightness detection boss, and the vacuum nozzle and the vacuum pump are connected through an air path, a PLC control system box is fixedly installed on one side of the battery shell quality inspection lower mold base, and the electric rotating rod, vacuum sensor, vacuum pump and PLC control system box are electrically connected.

[0008] As a preferred solution of the utility model, a first electric telescopic cylinder is embedded and installed on both sides of the airtightness detection boss near the inside of the lower mold base for quality inspection of the battery shell, and a locking buckle is movably installed at one end of the first electric telescopic cylinder near the airtightness detection boss, and edge sealing pads are pasted and installed around the top surface of the airtightness detection boss, and corresponding locking grooves are provided on both sides of the airtightness detection boss near the locking buckle.

[0009] As a preferred solution of the utility model, the top surface of the battery shell quality inspection lower mold base is fixedly installed with a battery shell quality inspection upper mold base through a column, and a battery shell positioning fixture is movably installed at the center of the top surface of the airtightness detection boss between the battery shell quality inspection upper mold base and the battery shell quality inspection lower mold base through a second electric telescopic cylinder.

[0010] As a preferred solution of the utility model, bearing rings are fixedly installed on both sides of the airtightness detection boss near the electric rotating rod, balls are movably installed around the inner wall of the bearing ring, and the electric rotating rod passes through the inner center of the bearing ring.

[0011] Beneficial effect: In view of the low efficiency of traditional manual inspection methods in the prior art on high-speed production lines, and the risk of missed inspections and detection errors, and the inability to ensure the qualified rate of battery shell processing, in the utility model, a vacuum pump is set up to work, and a vacuum nozzle is used to vacuum the inside of the battery shell placed on the top surface of the airtightness detection boss. At the same time, the vacuum sensor detects the vacuum environment and can maintain the vacuum state for a certain period of time, indicating that the airtightness of the battery shell is good and has no defects. At this time, the electric rotating rod rotates to the side close to the qualified discharge channel, and the battery shell that has completed the inspection will pass through the qualified discharge channel and fall into the automatic conveying device to enter the next processing step. If the vacuum state cannot be maintained for a certain period of time, the electric rotating rod rotates to the side close to the unqualified discharge channel for removal, and returns using the automatic conveying device. The automatic airtightness detection removes the unqualified battery shells, thereby improving the processing efficiency, avoiding the risk of missed inspections and detection errors, and ensuring the qualified rate of battery shell processing.
