Groove type alkali polishing and cleaning equipment

Abstract

The invention discloses trough type alkali polishing and cleaning equipment, and relates to the technical field of solar cell production equipment. A clamping mechanism used for clamping and fixing a wafer is arranged in a cleaning groove of the equipment, the clamping mechanism comprises a suction cup used for adsorbing and fixing the wafer, the suction cup is movably connected into the cleaning groove through a fixing base, a movable block is connected to the inner side wall of the cleaning groove in a sliding mode, and the movable block and the fixing base are fixed through a linkage rod. The movable blocks are symmetrically arranged on the two opposite side faces in the cleaning groove, the two movable blocks are symmetrically arranged on each side face, the positions of the fixing bases for fixing the wafers can be adjusted, the overall distance between the fixing bases can be reduced when the sizes of the wafers are small, and the overall distance between the fixing bases can be increased when the sizes of the wafers are large. Therefore, mutual adaptation between the fixed seat and the wafer is realized, the fixed seat is always fixed at the corresponding position of the wafer, the problem that the wafer cannot be fixed or the edge of the wafer is damaged is avoided, and the wafer can be prevented from being damaged by a harder connecting point.

Description

technical field [0001] The invention relates to the technical field of solar cell production equipment, in particular to a trough-type alkali polishing and cleaning equipment. Background technique [0002] The solar cell module is composed of high-efficiency monocrystalline / polycrystalline solar cells, low-iron ultra-white suede tempered glass, packaging materials (EVA, POE, etc.), functional backplane, interconnection bars, bus bars, junction boxes and aluminum alloy frames. . Its service life can reach 15-25 years. [0003] A single solar cell cannot be used as a power source directly. As a power supply, several single cells must be connected in series, connected in parallel and tightly packaged into components. The solar cell module is the core part of the solar power generation system and the most important part of the solar power generation system. [0004] In the production of solar cell modules, polishing and cleaning equipment is required. In order to improve pr...

Problems solved by technology

[0006] This kind of cleaning equipment has the advantage that the wafer is cleaned more thoroughly, and it is convenient to quickly dry the cleaned wafer. However, when this cleaning equipment cleans the wafer, it needs to fix the wafer as a whole in the cleaning tank. The existing fixing structure exists The connection point is hard, and it is easy to damage the chip under the action of washing. At the same time, the position of the fixed point is constant. If the size of the chip is large, the fixed point is close to the middle of the chip, which will easily cause damage to the chip at the edge. There is a problem that the fixed point is far away and cannot be fixed
