Weighing and sorting device for lithium battery pole pieces

Abstract

The invention discloses a weighing and sorting device for lithium battery pole pieces. The device comprises a weighing tray, a base and an infrared ranging instrument, wherein a controller is arrangedat one end of the top part of the base, and the bottom end of the top part of the base is rotatably connected to a conveyor belt through a rotating shaft; a sensor frame is welded on the top part ofthe base and is close to the middle part of the conveyor belt; and the infrared ranging instrument is arranged in the inner center of the sensor frame. According to the weighing and sorting device forthe lithium battery pole pieces, the infrared ranging instrument is arranged on the top part of the conveyor belt; the thickness of the pole pieces is fixed, so that the quantity of the pole pieces can be determined by measuring the thickness of the pole pieces, and then whether the weight meets standard can be determined based on the quantity; with the adoption of the abovementioned sorting mode, a plurality of pole pieces can be synchronously weighed, so that the sorting efficiency is extremely improved; and moreover, no requirements are proposed to the quantity of the pole pieces, so thatthe sorting speed is further increased.

Description

technical field [0001] The invention relates to the technical field of lithium battery equipment, in particular to a lithium battery pole piece weighing and sorting device. Background technique [0002] "Lithium battery" is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. In 1912, the lithium metal battery was first proposed and studied by Gilbert N. Lewis. In the 1970s, M.S.Whittingham proposed and began to study lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, lithium batteries have become the mainstream now. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Li-ion batteries do not ...

Problems solved by technology

[0003] Lithium battery pole pieces are one of the essential components in the application of lithium batteries. The sorting of lithium battery pole pieces is very important. However, the existing sorting devices still have deficiencies in the process of use. First of all, , the existing sorting devices are often only capable of weighing a single or a fixed number of pole pieces and then sorting them. However, such weighing methods are relatively inefficient in actual use, and the sorting process requires The number of pole pieces is required, and the operation is troublesome; secondly, the existing weighing and sorting devices often need to separate weighing and sorting, or require manual intervention, such a sorting process is slow and has a high error rate , not conducive to sorting
