Abstract

The invention discloses a lithium battery end cover pressing machine which comprises a rack, a workbench arranged on the rack, a chained end cover die, a rolling wheel type pressing head, bearings arranged at the two ends of a middle shaft of the pressing head, bearing pedestals, a driving motor connected with the middle shaft, and a pulse oil pump connected to the bearing pedestals. The end cover die comprises die units and a hinge structure connected between the die units. An end head is arranged on a rolling wheel of the pressing head, and matched with pressing grooves in the surfaces of the die units. According to the lithium battery end cover pressing machine, due to the fact that the chained end cover die and the rolling wheel type pressing head are arranged, continuous pressing of a lithium battery end cover is achieved, and pressing efficiency is improved.

Description

[0001] technical field [0002] The invention relates to a lithium battery processing equipment, in particular to a lithium battery end cover pressing machine. Background technique [0003] Lithium battery refers to a battery containing lithium (including metal lithium, lithium alloy, lithium ion, lithium polymer) in the electrochemical system. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium metal batteries are generally non-rechargeable and contain lithium in a metallic state. Li-ion batteries do not contain metallic lithium and are rechargeable. Lithium batteries usually come in two shapes: cylindrical and square. The inside of the battery adopts a spiral wound structure, and a very fine and highly permeable polyethylene film separator material is used to space the positive and negative electrodes. The positive electrode includes a current collector composed of lithium cobalt oxide (or lithium...
