In step S18, when it is determined that the package bag in the palletizing box is not full, the package bag is returned to the palletizing box.

In step S19, if it is determined that the number of injection-molded articles in the acceptable article box is smaller than the preset value, it is returned to determine whether or not the injection-molded articles are acceptable articles.

In step S20, when it is determined that the injection molded article is not a conforming article, the injection molded article is conveyed to a conforming article box.

In steps S10 to S20, the injection molded article is detected, and if the injection molded article is a conforming article, the injection molded article is conveyed into the conforming article box 11. After the lithium battery accessories in the qualified product boxes 11 reach the preset number, the qualified product boxes 11 are switched to store, and meanwhile the full qualified product boxes 11 are packed and packaged. The mechanical arm 24 stacks the packaged lithium battery accessory packaging bags 20, and finally seals the case and runs off the line. The forming method can effectively ensure the detection precision of the lithium battery accessories, namely the offline quality, and the connection among the components is stable and rapid, so that the offline efficiency of the lithium battery accessories is effectively improved.
