Embodiment Construction

[0015] The present invention will be described in detail in conjunction with accompanying drawing now. This figure is a simplified schematic diagram only illustrating the basic structure of the present invention in a schematic manner, so it only shows the components relevant to the present invention.

[0016] Such as Figure 1-2 As shown, a visual solar cell panel fragmentation detection mechanism of the present invention includes a conveyor belt 1, a vacuum adsorption assembly and a visual detection assembly. The solar cell panels 2 are placed on the conveyor belt 1 at equal intervals, and the vacuum adsorption assembly includes several adsorption plates. 3. The adsorption plate 3 is located under the conveyor belt 1. There is a cavity 4 inside the adsorption plate 3. The interior of the cavity 4 is connected to the negative pressure system 16. The upper end of the adsorption plate 3 has a plurality of through holes connecting the cavity 4 and the outside. 5. The conveyor be...

Abstract

The invention provides a visual detection mechanism for crack of a solar cell panel. The visual detection mechanism comprises a conveyor belt and a visual detection assembly. Solar cell panels are placed on the conveyor belt at an equal interval; the visual detection assembly comprises a first camera, first lens and first light source arranged over a solar cell panel about to enter a welding station, a second camera, second lens and second light source arranged over a solar cell panel having departed from the welding station, a data acquisition card, a display unit and an industrial control computer, wherein the first camera and the second camera are successively connected with the data acquisition card and the industrial control computer in a line connection manner, and the display unit is in line connection with the industrial control computer. The visual detection mechanism for crack of the solar cell panel employs combinations of the cameras, the lenses and the light sources to replace artificial detection of cracks on the solar cell panel, can effectively improve the detection speed and precision of a production line and prevents misjudgement and leak detection caused by fatigue of eyes of workers.

Description

technical field [0001] The invention relates to the technical field of solar cell panel manufacturing, in particular to a visual solar cell panel fragmentation detection mechanism. Background technique [0002] The existing solar cell module process mostly adopts automatic production, and its process includes cell sorting-single piece welding-string welding-stacking-inspection-lamination-curing-installation of frame and junction box --wipe--safety test--final test--final inspection-package and other links, among which, single-piece welding and series welding of cells can be carried out at the same time by welding machine, which can simplify the welding process. [0003] At present, the heat source used by the welding machine is an infrared lamp. Using the thermal effect of infrared rays, the ribbon can be spot-welded on the main grid line in the form of multiple points. The length of the ribbon is about twice the side length of the battery, and the extra ribbon is connected...
