Automatic diaphragm pressing and pole piece pressing group lamination carrying device

Abstract

The invention discloses an automatic diaphragm pressing and pole piece group pressing lamination carrying device which comprises a lamination platform and a driving mechanism. The driving mechanism is horizontally arranged at a lamination station, and a platform space is arranged in the driving mechanism. The driving mechanism comprises a jacking assembly, two sets of cutting assemblies and two sets of film pressing assemblies, wherein the jacking assembly is arranged below the platform space, and the two sets of cutting assemblies and the two sets of film pressing assemblies are arranged on the left side and the right side of the platform space correspondingly. The lamination platform is movably arranged in the platform space, and comprises a bearing assembly and material pressing assemblies. The bearing assembly is horizontally arranged. The two pressing assemblies are arranged on the left side and the right side of the bearing assembly correspondingly. According to the invention, automatic lamination bearing and pole piece group carrying are realized, the waiting time is shortened, the capacity of the whole line is improved, a self-pressing function is realized, the stability of a pole piece group carrying position is ensured, automatic connection of lamination and pole piece group carrying is ensured, automatic film pressing is realized, interference with pole piece lamination is avoided, and automatic connection of film pressing and lamination is effectively ensured.

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
