Special device for thermal infrared imager test of laminate

Abstract

The invention relates to a special device for thermal infrared imager test of a laminate, comprising a framework, an upper track, a lower track, a rolling circuit closer and a bottom rolling rubber wheel. The framework comprises two vertical rods, the upper sections of the two vertical rods are provided with upper track regulating tanks, and the middles of the two vertical rods are provided with circuit closer regulating tanks. The upper track and the lower track are fixedly installed on the two vertical rods with equal height. A battery laminate is inserted into notches of the upper track and the lower track, and the rolling circuit closer is in contact with the anode and the cathode of the battery laminate. Since an insertion sliding structure is adopted among the battery laminate, the upper track and the lower track, and the distance between the upper track and the lower track can be regulated, the testing requirement of battery laminates with different specifications can be met. The sliding type power connection testing device greatly simplifies the operation of the operating personnel in a darkroom, reduces the labor intensity, improves the detecting efficiency without damaging the battery laminate, avoids the tedious operation process for respectively clamping the anode and the cathode, and thoroughly puts an end to false connection of the anode and the cathode.

Description

Technical field: [0001] The invention relates to a device for testing a photovoltaic module, in particular to a special device for testing an infrared thermal image of a laminate. Background technique: [0002] The main production process of photovoltaic modules is to laminate raw materials such as glass, solar cells, plastic packaging materials and back sheets, and vacuumize and heat them through a laminator. The semi-finished product before the frame is called a laminate. Fractures or hidden fractures of the cells in the laminate will cause the battery to open. This failure will affect the life of the module, so it is necessary to inspect the laminate before framing. In the dark room, the laminate is fed with current, and the cooled CCD image sensor is used to capture the light emitted by the current-passed battery to generate an image. Observing the situation of the battery from the image is a method that is currently used more. The current method of passing current thr...
