Automatic marking device for positive and negative poles of lithium ion battery

Abstract

The invention relates to the technical field of lithium ion battery positive and negative pole marking, and discloses an automatic marking device for positive and negative poles of a lithium ion battery. The automatic marking device comprises a base plate, screws are fixedly arranged and are connected to the left end and the right end of the base plate in a rotating mode, and a fixing plate is fixedly arranged between the screws. According to the marking device, the lithium battery is moved to the lower end of the fixing plate through a conveying device on the base plate, then the fixing plateis driven to downwards get close to the lithium battery under the action of the screws, a groove body in the fixing plate is wrapped around a lithium battery body, then a driving rod is started to drive a detection rod to make contact with the upper end of the lithium battery, the detection rod can detect the existence of voltage, then the voltage is transmitted to magnetic wheels through wires,if the negative pole is detected, an electromagnetic toothed plate is negatively charged, S magnetism is presented, the magnetic wheel at the left end is attracted to rotate towards the inner side, the magnetic wheel at the right end is attracted to rotate towards the two sides, and therefore the magnetic wheel at the left end can mark the upper end of the lithium battery body, and the automatic marking effect is achieved.

Description

technical field [0001] The invention relates to the technical field of marking the positive and negative poles of lithium ion batteries, in particular to an automatic marking device for positive and negative poles of lithium ion batteries. Background technique [0002] Lithium-ion battery is a secondary rechargeable battery. It has positive and negative electrodes. The principle of use is to use a type of lithium metal or lithium alloy as the positive and negative electrodes and use a non-electrolyte solution. Lithium batteries are also divided into lithium metal Batteries and lithium-ion batteries, during the installation of lithium batteries, we need to distinguish the positive and negative electrodes of lithium batteries. [0003] At present, the main installation process of lithium batteries is manually installed. Before installation, it is necessary to judge the positive and negative poles. Generally, the positive and negative poles are measured manually. It is also ex...
