An automatic diaphragm pressing and stacking device for pressing pole pieces

Abstract

The invention discloses a lamination carrying device for automatically pressing diaphragms and pressing electrode groups, which comprises a lamination platform and a driving mechanism. Components, cutting components and film pressing components, the jacking component is set under the platform space, the material cutting component and film pressing component include two groups, which are respectively set on the left and right sides of the platform space; the lamination platform can be set in the platform space movably Inside, the lamination platform includes a bearing component and a pressing component, and the bearing component is arranged horizontally; the pressing component includes two sets, which are respectively arranged on the left and right sides of the bearing component. The invention realizes the automatic loading of laminations and pole piece groups, reduces the waiting time, improves the production capacity of the whole line, has the function of self-pressing material, ensures the stability of the carrying position of the pole piece group, and ensures the stability of the lamination and pole piece groups. The automatic connection of the carrier realizes automatic lamination and avoids interference with the pole piece lamination, effectively ensuring the automatic connection between the lamination and the lamination.

Description

technical field [0001] The invention relates to the field of automation equipment, in particular to an automatic diaphragm pressing device and a lamination carrying device for pressing pole piece groups in the field of automatic production equipment for lithium-ion power batteries. 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 electrol...

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
