Problems solved by technology

Since the optimal grinding gap between the three rollers of the existing three-roller grinding machine cannot be precisely controlled at one time, it is operated purely by the operator's debugging experience, which has high technical requirements for the operator, and human factors have little influence on the quality of the silver paste. large, and the product quality fluctuates greatly, which is the biggest defect of the existing three-roll mill, which directly affects the quality of the silver paste

Abstract

The invention relates to a roller spacing adjustment alarm prompting device comprising a front roller, a rear roller, four optoelectronic switches and an alarm, wherein the left sides and the right sides of the front roller and the rear roller are respectively provided with one optoelectronic switch. When the front roller and the rear roller are at the best position, the probing light beams of the optoelectronic switches are respectively aligned to different buses of the same side of the upper circular arc of the corresponding roller, and the four optoelectronic switches are connected with the alarm after being connected in parallel. An operator can rapidly and accurately adjust the front roller and the rear roller to the best grinding positions according to the prompt of the alarm only by respectively rotating corresponding hand wheels. The invention not only is convenient and rapid to operate but also has good repeatability, reduces the technical skill demand on operation staffs, can more stably ensure the silver paste grinding quality and eliminates the human influencing factor.

Description

technical field [0001] The invention relates to a production device of silver paste for battery sheets, in particular to an infrared control device of silver paste grinding equipment. Background technique [0002] Conductive silver paste is a viscous paste composed of high-purity (99.9%) metallic silver particles, binders, solvents, and additives. Conductive silver paste has very strict requirements on its components, and the particle size, shape and content of metallic silver are closely related to the performance of silver paste. [0003] Metallic silver particles are the main component of conductive silver paste, and the conductive properties of solar cells are mainly reflected by it. The content of metal silver particles in the paste is directly related to the conductivity. In a sense, the higher the content of metal silver particles, the better the conductivity of the silver paste. But when its content exceeds the critical volume concentration , its conductivity canno...
