Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery production equipment, and in particular to a liquid injection device and a transportation device for a liquid injection jig for a battery. Background Art

[0002] Liquid injection and resting are crucial processes in lithium battery production. A liquid injection jig is assembled from a liquid injection cup carrier loaded with liquid injection cups and a battery cell carrier loaded with battery cells. The liquid injection cups and battery cells are docked together, and the liquid injection jig then completes liquid injection during the liquid injection process and resting during the resting process. After liquid injection and resting, the battery cell carrier needs to be unloaded and reloaded, and the liquid injection cups in the liquid injection cup carrier also need to be cleaned.

[0003] The liquid injection equipment mostly uses automated means to achieve the above process. Usually, the battery cell carrier to be unloaded is taken out from the liquid injection equipment, and other loaded battery cell carriers are placed into the liquid injection equipment. The liquid injection cup carrier to be cleaned is taken out from the liquid injection equipment, and the cleaned liquid injection cup carrier is placed into the liquid injection equipment. The liquid injection equipment can use automated means to assemble and separate the liquid injection cup carrier and the battery cell carrier.

[0004] However, this type of liquid injection equipment usually requires two transport devices, one for transporting the liquid injection jig to be separated after liquid injection and the other for transporting the liquid injection jig to be injected after assembly. This will undoubtedly affect the automated production process of the liquid injection equipment and increase production costs for manufacturers. On the other hand, when the liquid injection equipment is loading and unloading battery cells, the battery cell carrier that has been injected is usually removed from the transport device and replaced with a battery cell jig loaded with liquid to be injected. This may cause the position of the battery cell carrier to shift, affecting the assembly accuracy of the liquid injection cup carrier and the battery cell carrier and the positioning accuracy of the liquid injection jig.
