Embodiment Construction

[0014] The present invention will now be described in detail with reference to the drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the present invention in a schematic way, so it only shows the structure related to the present invention.

[0015] Such as Figure 1-2 As shown, a pressure-type solar panel chipping detection mechanism of the present invention includes a conveyor belt 1, a vacuum suction assembly and a pressure detection assembly. The conveyor belt 1 is provided with multiple rows of through holes 2 along the conveying direction of the conveyor belt 1. This embodiment The through holes 2 are in four rows. The distance a between the two outermost rows of through holes 2 is smaller than the side length b of the solar panel 3 in the width direction of the conveyor belt. The solar panel 3 is placed on the upper surface of the conveyor belt 1 and follows the conveyor belt. 1 move together, the vacuum suction assembly...

Abstract

The invention provides a pressure type solar panel cracking detection mechanism. The pressure type solar panel cracking detection mechanism comprises a conveying belt, a plurality of vacuum adsorption assemblies and a pressure detection assembly; a plurality of rows of through holes are formed in the conveying belt; the distance between two rows of through holes at the outmost side is smaller than the length of sides of solar panels at the width direction of the conveying belt; each vacuum adsorption assembly comprises an adsorption plate located below the conveying belt; a cavity is formed in the adsorption plate; a plurality of through holes communicated with the cavity and the outside are formed at the upper end of the adsorption plate; the pressure detection assembly includes pressure sensors, a measuring circuit and a display device; the pressure sensors are arranged on the inner walls of the cavities; and the pressure sensors are in line connection with the measuring circuit and the display device outside the cavities successively. According to the pressure type solar panel cracking detection mechanism of the invention, the pressure sensors are adopted to monitor pressure change in the cavities in the adsorption plates, and therefore, automatic detection of the cracking of the solar panels can be realized, and the reliability of a welding system can be improved, and influence on downstream processes can be avoided, and work efficiency can be improved.

Description

Technical field [0001] The invention relates to the technical field of solar cell panel manufacturing, in particular to a pressure-type solar cell panel cracking detection mechanism. Background technique [0002] The existing solar cell module process flow mostly adopts automated production, and its process flow includes cell sorting-single chip welding-string welding-stacking-intermediate inspection-lamination-curing-frame mounting and junction box --Wipe--Safety test--Final test--Final test--Packaging, etc. Among them, the single-chip welding and string welding of the cell can be carried out simultaneously with a welding machine, which can simplify the welding process. [0003] At present, the heat source for welding of the welding machine is an infrared lamp, and the welding tape can be spot welded on the main grid line in the form of multiple points by using the thermal effect of infrared. The length of the solder ribbon is approximately twice the length of the battery side, a...
