Embodiment Construction

[0023] The core of the invention is to provide an EL tester to improve the accuracy of the code scanning process.

[0024] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] Please refer to figure 2 As shown, the embodiment of the present invention discloses an EL tester, which includes a darkroom box 4 and a code scanner 3, wherein the scanner 3 is movably arranged inside the darkroom box 4 as the main component for scanning the barcode 2, And be installed on the top of the solar cell panel 1 at the stop position of the darkroom box body 4 . In order to complete the detection of the EL tester, it is necessary to take pictures of the stationary solar cell panel 1 to save the picture. Therefore, after the laminated solar cell panel 1 is transported to the detection position inside the darkr...

Abstract

The invention provides an EL tester. The EL tester comprises a darkroom box body and a code scanner, wherein the code scanner is movably arranged inside the darkroom box body and is arranged above a solar cell panel at a stopping position of the darkroom box body; the EL tester also comprises a driving device connected with the code scanner so as to drive the code scanner to realize scanning through bar codes. During working, after the solar cell panel moves to a detection position and stops, the driving device starts and drives the code scanner to move to realize the scanning for the bar codes, thus code scanning is completed. According to the EL tester, the code scanner is arranged inside the darkroom box body and can movably scan still bar codes, thus the problem that scanning is not completed by the code scanner due to ultrahigh speed of a conveyor belt is prevented, the accuracy of code scanning process is improved, and the accuracy of final detection is further improved.

Description

technical field [0001] The invention relates to the technical field of solar cell production, in particular to an EL tester. Background technique [0002] In the production process of solar cells, it is necessary to inspect the laminated solar cell components to judge whether there are quality problems in the cells inside the solar cell panel, so as to improve the quality of the product. [0003] The EL (solar cell module defect detection) tester is to make the internal cells of the solar cell panel glow by energizing the solar cell panel, and use a camera to take pictures of the luminous solar cell panel, and then judge the internal cells of the solar cell panel through the photos Whether there is an instrument with quality problems. [0004] In order to facilitate the traceability of the solar panel corresponding to the photo, a barcode is usually set on the solar panel. During the detection process, it is necessary to save the picture barcode and the barcode on the solar...
