A platform circulation supply lamination production line and its circulation lamination process

Abstract

The invention discloses a platform circulation supply lamination production line and its circulation lamination process, comprising a lamination mechanism, a lamination platform, a driving mechanism, a lifting mechanism, a slide rail and a rubber-coated blanking mechanism. The upper slide rail and the lower slide rail are arranged at intervals in parallel directions, and the two sides of the upper slide rail and the lower slide rail are respectively equipped with lifting stations, and the upper slide rail is provided with a stacking station, and one end of the lower slide rail is provided with a blanking station; The stacking platform is slidably set on the slide rail; the lifting mechanism includes two sets, which are respectively set at the lifting stations on both sides; the driving mechanism is set at the stacking station, and the stacking mechanism is set above the stacking station; The glue blanking mechanism is arranged outside the blanking station. The invention adopts the circular movement of the lamination platform along the rectangular path, which greatly improves the production capacity of the whole line, ensures the stability of the carrying position of the pole piece group, realizes automatic film pressing and avoids interference with the pole piece lamination, and realizes the automatic encapsulation At the same time, it maintains continuous pressing to effectively ensure the quality of the lagging.

Description

technical field [0001] The invention relates to the field of automation equipment, in particular to a platform circulation supply lamination production line and its circulation lamination process in the field of lithium ion power battery automation production equipment. Background technique [0002] Lithium battery refers to batteries containing lithium in the electrochemical system, including metal lithium, lithium alloys, lithium ions, and lithium polymers. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium battery is a rechargeable battery that mainly relies on lithium ions to move between positive and negative electrodes to work. During charging and discharging, lithium ions intercalate and deintercalate back and forth between the two electrodes: when charging the battery, lithium ions are deintercalated from the positive electrode, inserted into the negative electrode through the electrolyte, and the...

2. The traditional lamination platform adopts a fixed structure, that is, after the lamination mechanism and the film covering mechanism are laminated on the lamination platform to form a pole piece group, then the pole piece group is taken out and the pole piece group is fixed with glue. There is a waiting time for the two processes of lamination and encapsulation. For example, the encapsulation process can only be carried out after the lamination is completed to form a pole piece group, which affects the production capacity; material time problem

5. As mentioned above, the positive and negative electrodes and diaphragms in the pole piece group are prone to misalignment. Therefore, the pole piece set on the stacking platform needs to be fixed with glue. The external covering tape fixes the positions of the pole pieces and diaphragms in it for subsequent processing; therefore, it is necessary to solve the problem of automatic encapsulation of the pole piece group, and at the same time, it is necessary to solve the problem of each pole piece and diaphragm in the pole piece group during the encapsulation process. The position of the diaphragm is prone to misalignment
