Abstract

The invention discloses a device and method for detecting bubbles of a solar photovoltaic panel. The device comprises a first sliding mechanism, a second sliding mechanism and a controller. The firstsliding mechanism comprises a first guiding rail, a connecting rod and a first slider, the first guiding rail and the connecting rod are connected by a fastener, the first slider slides along the transverse direction of the first guiding rail, and the first slider is provided with the second sliding mechanism. The second sliding mechanism includes a second guiding rail and a second slider slides along a longitudinal direction of the second guiding rail. The top and bottom of the second slider are respectively provided with an X-ray imaging system and a light receiving and transmitting device.The controller controls the first slider mechanism and the second slider mechanism to move to an area to be detected, the controller compares light signals transmitted and received by the light receiving and transmitting device and controls the X-ray imaging system to move to a bubble distribution area to take a photo. According to the invention, the comprehensive detection of the solar photovoltaic panel is achieved, and the distribution densities and sizes of the bubbles can be accurately determined.

Description

technical field [0001] The invention belongs to the technical field of solar photovoltaic panel production, and particularly relates to a solar photovoltaic panel air bubble detection device and a detection method thereof. Background technique [0002] The production process of solar photovoltaic panels is battery inspection, front welding, inspection, back connection, inspection, laying (glass cleaning, material cutting, glass pretreatment, laying), lamination, deburring (deburring, cleaning), assembly Frame (glue coating, corner keying, punching, framing, scrubbing residual glue, welding junction box, high voltage test, component test, appearance inspection, packaging and storage). [0003] The solar photovoltaic panel lays tempered glass, EVA layer, battery sheet, EVA layer, glass fiber and back sheet in order to prepare for lamination, but during lamination, due to the great pressure on the solar photovoltaic High temperature is required during lamination, and the gas g...
