Description

This disclosure claims priority to Chinese patent application No. 202323067523.1, “Cover Removal Device and Battery Electrolyte Injection Equipment,” filed with the China National Intellectual Property Office on November 14, 2023, and its entirety is incorporated herein by reference. This disclosure relates to the technical field of lithium battery equipment, and more particularly to cover removal devices and battery electrolyte injection equipment. After placing the lithium battery in its outer casing, it needs to be placed in a battery electrolyte injection facility for electrolyte injection. During the injection process, typically, multiple batteries are placed in batches on a tray and placed in the battery electrolyte injection facility. Then, an upper cover containing multiple electrolyte cups is placed above the tray. Each of the electrolyte cups is connected to the electrolyte injection port of a battery, and a fixed amount of electrolyte is injected into each cup. The electrolyte can then gradually flow into the battery through the drain hole at the bottom, thereby successfully injecting the electrolyte into the battery. The top cover and the electrolyte cup on top of it also place the battery in an isobaric cavity, circulating positive and negative pressure, allowing it to settle and thereby promoting electrolyte absorption. After settling is complete, the entire top cover can be removed from the tray, allowing the battery to move on to the next process. However, due to factors such as the tilt of the electrolyte cup or blockage of the drain hole, smooth electrolyte dispensing may not be possible, potentially leaving electrolyte residue in the cup even after dispensing is complete. When removing the top cover from the tray, this residual electrolyte can leak, contaminating the batteries in the tray. This can lead to problems such as battery reprocessing or disposal, increasing maintenance work. Therefore, to solve the above problem, we provide a cover removal device and battery electrolyte injection equipment that can effectively prevent the electrolyte from contaminating the battery. A cover removal device, Rack and, A transport mechanism mounted on the rack, comprising a lifting assembly, a gripping assembly, and a plurality of closing assemblies, wherein the gripping assembly can grasp and release an upper cover containing a plurality of liquid dispensing cups, and can move along the vertical direction under the drive of the lifting assembly to remove the upper cover from the tray, and each of the closing assemblies includes a stopper, The closing assembly can move together with the gripping assembly, and when the gripping assembly grips the upper cover, the plugs of the multiple closing assemblies can each extend into the multiple liquid injection cups and close the drain holes of the liquid injection cups. In one embodiment, the gripping assembly includes a support plate, a drive member, and two opposing clamp plates, the support plate being connected to the drive end of the lifting assembly, a positioning pin provided on one side of each clamp plate facing the other clamp plate, the two clamp plates slidably mounted on the support plate, and the drive member capable of driving the two clamp plates toward or toward each other, thereby inserting or removing the positioning pins into mounting holes on the side of the upper cover. In one embodiment, the transport mechanism further includes a base plate for supporting the lifting assembly, the gripping assembly, and the closing assembly, the base plate being mounted on the rack, the gripping assembly further including a guide rod extending in the vertical direction, the base plate being provided with a linear bearing, the guide rod being slidably drilled into the linear bearing, and one end thereof being connected to the support plate. In one embodiment, multiple closing assemblies are attached to the support plate and can move along the vertical direction together with the support plate. In one embodiment, the stopper can elastically contact the bottom of the liquid dispensing cup along the vertical direction. In one embodiment, each closing assembly further includes a base and an elastic member, wherein the stopper is slidably mounted on the base along the vertical direction, and the elastic member applies a downward tightening force to the stopper. In one embodiment, the base is columnar, and the elastic member is a compression spring fitted to the base and in contact with the plug. In one embodiment, the system further includes a waste discharge carrier provided on the rack, wherein the transport mechanism can move along a predetermined direction perpendicular to the vertical direction, thereby driving the gripping assembly to move above the waste discharge carrier, and the gripping assembly moves along the vertical direction under the drive of the lifting assembly, allowing the gripped upper cover to be placed on the waste discharge carrier.
