Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automation transportation, especially to a battery roll core transportation tray. BACKGROUND

[0002] In the battery roll core production process, after the battery roll core completes the last process operation, it needs to be transported to the next process by the material line tray. The existing battery roll core transportation tray directly bears the battery core by the tray without any anti-collision protection mechanism. In the transfer process, the vibration and shaking of the conveying line are inevitable, and the four corners of the battery roll core are prone to knock with the tray, causing the dust on the surface of the battery roll core to fall off. Part of the falling dust will fall into the battery, affecting the battery performance, even causing the battery to be scrapped, and in severe cases, causing internal short circuit of the battery, which poses a serious safety hazard.

[0003] A "lithium battery square battery double roll core tray" is disclosed in Chinese patent documents, with publication number CN219155021U. The utility model discloses a lithium battery square battery double roll core tray, which comprises a tray bottom plate, a roll core placement area is arranged on the tray bottom plate, and a tray merging installation assembly is arranged on the tray bottom plate. The tray merging installation assembly comprises a protruding part arranged on the tray bottom plate, and the protruding part can be fixed by a merging installation block to realize the merging of the tray. The lithium battery square battery double roll core tray improves the tray core loading capacity and improves the production capacity. The tray can be used alone or merged according to the needs of different processes, which can reduce the types of trays and reduce the cost of trays. However, the tray does not have an anti-collision protection function, and the four corners of the battery roll core are prone to knock with the tray due to vibration and shaking of the conveying line, causing the dust on the surface of the battery roll core to fall off. Part of the falling dust will fall into the battery, affecting the battery performance, even causing the battery to be scrapped, and in severe cases, causing internal short circuit of the battery, which poses a serious safety hazard.
