Coating spraying device for black silicon production

Abstract

The invention relates to the technical field of black silicon production, and discloses a coating spraying device for black silicon production. The coating spraying device comprises two support plates, two stabilizing pads are fixedly installed at the bottoms of the two support plates, and a stabilizing support is fixedly installed at the position of a crack formed by the two support plates. Two electric push rods are fixedly installed at the tops of the two support plates, and electric extension rods corresponding to the electric push rods are movably installed at the tops of the four electric push rods. According to the coating spraying device for black silicon production, by arranging a conveying rolling shaft, and sleeving a conveying belt on the outer surface of the conveying rollingshaft, under the driving of a power motor, the effects that the conveying belt can be driven to operate, and a to-be-machined silicon plate is driven to move at a uniform speed, are achieved; by arranging the electric push rods, the height of a top base can be conveniently adjusted according to machining requirements, and by arranging a spraying column head, the effect that workpieces on the conveying belt can be uniformly sprayed by the spraying column head, is achieved.

Description

Technical field [0001] The invention relates to the technical field of black silicon production, in particular to a coating spray device for black silicon production. Background technique [0002] Generally speaking, black silicon is to make the silicon wafer black. The silicon wafer is still the original silicon wafer. A layer of paint is used on the surface to reduce the reflection, so that the silicon wafer looks black. The preparation method is Brush the coating so that there are bumps on the surface. The main component of the coating is silicon dioxide. We see that the existing silicon cells are all blue, and there are grids on them. Passivation is done. The purpose of passivation is to reduce reflection and remove dangling bonds, but we still look blue and bright, so black silicon is much better than existing passivation. [0003] Existing passivation requires strict temperature requirements and vacuum. This black silicon material can capture almost all sunlight. It is like ...
