On-line appearance detecting machine after lamination of solar cell panels

Abstract

The invention relates to an on-line appearance detecting machine after lamination of solar cell panels, which comprises a main machine frame, a turnover mechanical arm and a drive device for driving the turnover mechanical arm to turn over, wherein the turnover mechanical arm and the drive device are arranged on the main machine frame. At least two sucking discs are arranged on the turnover mechanical arm, a placing frame for placing the solar cell panels is obliquely arranged on the main machine frame in the upward turning-over direction of the turnover mechanical arm, and the lower portion of the placing frame is provided with a stop opening for preventing the solar cell panels from falling down. The solar cell panels are turned over from bottom to top by the turnover mechanical arm, the fixing is achieved by sucking glass surfaces of the solar cell panels, the just-laminated solar cell panels which are not influenced, quality hidden danger caused by sucking force is avoided, and the product quality is improved. When the on-line appearance detecting machine performs detection, operation is completely exposed in the presence of detecting workers, the detection is performed in place, and detection of dead corners is avoided.

Description

technical field [0001] The invention relates to the technical field of photovoltaic module appearance inspection equipment, in particular to an online appearance inspection machine for laminated solar panels. Background technique [0002] Crystalline silicon photovoltaic modules (also called solar cell modules) are the core part of the solar power generation system and the most valuable part of the solar power generation system. Its function is to convert the solar energy into electrical energy, or store it into the battery, or promote work load. The quality and cost of solar panels will directly determine the quality and cost of the entire system. [0003] Solar laminates are the most commonly used type of crystalline silicon photovoltaic modules. Tempered glass, EVA, solar cells, EVA, and back sheets are placed in a solar vacuum laminator in sequence for vacuum lamination. After about 20 minutes of lamination Take it out after operation, and a solar laminate comes out. ...

Problems solved by technology

Some of the existing technologies use manual flipping to reduce costs, which is less efficient and has potential safety hazards

There is also a method of mechanical overturning, such as the appearance inspection machine disclosed in Chinese Patent Application No. ZL 201120197977.9, which uses a turning mechanism to drive a swing support device to turn over the laminate, and the swing claws of the swing support device play a role in fixing and supporting the laminate. function, but swinging claws will affect the viewing angle, and there is a blind spot

There are also those that use suction cups to absorb the laminate and turn it over to achieve appearance inspection, but after the solar laminate is laminated, the glass is on the bottom layer and the top layer is the backplane.

At this time, the suction force of the suction cup acts on the back plate, which will have a certain pulling force on the battery. Because the laminate has not been completely solidified at this time, it will leave a quality hazard for the battery. After long-term use, the hidden danger will be exposed. The chip does not work properly and the service life is shortened
