Solar panel bubble detecting device and detecting method thereof

Abstract

The invention provides a solar panel bubble detecting device and a detecting method thereof. The solar panel bulb detecting device includes a conveying belt, a linear light source, a CCD camera, a controller and a mechanical arm. The linear light source is arranged above the conveying belt in an inclined manner. The CCD camera is arranged above the conveying belt. The CCD camera is used for receiving light reflected by the solar panel after irradiating from the linear light source to the solar plane. The CCD camera and the mechanical arm are both in signal connection with the controller. The position of the linear light source and the position of the CCD camera are adjusted by utilizing the solar panel as the reference. The controller is utilized for contrasting received signals with a predetermined reference so as to test the solar panel and to judge whether bubbles exist in the solar panel or not. According to the invention, the different refractive indexes of light in an EVA layer and the bubbles are utilized and the CCD camera receives the light reflected by the solar panel after irradiating from the linear light source to the solar plane. Whether the position of light irradiating on the lens of the CCD camera surpasses a predetermined range or not is judged. Therefore, accuracy and efficiency are achieved and automation is realized.

Description

technical field [0001] The invention relates to the technical field of solar cell panel production, in particular to a solar cell panel air bubble detection device and a detection method thereof. Background technique [0002] The production process of solar panels is battery inspection, front welding, inspection, rear connection, inspection, laying (glass cleaning, material cutting, glass pretreatment, laying), lamination, deburring (deburring, cleaning), frame mounting (Glue application, corner key installation, punching, framing, scrubbing excess glue, welding junction box, high voltage test, component test, appearance inspection, packaging and storage). [0003] Such as Figure 4 As shown, the solar panel lays tempered glass 6, EVA layer 7, cell sheet 8, EVA layer, glass fiber and back sheet in order to prepare for lamination, but during lamination, due to the great pressure on the solar panel Large, and requires a very high temperature during lamination, and the gas gen...
