Double-station offline cell EL detection sorting device

Abstract

The invention discloses a double-station offline cell EL detection sorting device, and the device comprises a frame structure capable of moving freely, a first station detection line and a second station detection line, wherein the first station detection line and the second station detection line are located in the frame structure, are the same and are symmetrically arranged. Each of the two station detection lines comprises a material box conveying and lifting device, a sucking and rotating device, an EL detection device and a sorting and transplanting device. The material box transporting and lifting device is used for conveying the battery plate material box filled with the to-be-detected cell panel material sheet to the lower part of the sucking and rotating device, lifting the to-be-detected cell panel material sheet to a required height; the to-be-detected cell panel sheet is sent to a feeding line of the EL detection device through the sucking and rotating device, then enters the EL detection device, and emits light after being powered on and are photographed, wherein obtained pictures are sent to a master control machine to be analyzed, and whether the corresponding cell panel sheet is qualified or not is judged according to the pictures, and the numbering is conducted; the detected cell panel material sheet enters a material line of the sorting and transplanting device, and the qualified material sheets and unqualified material sheets are separated out through the sorting and transplanting device.

Description

technical field

[0001] The invention belongs to the field of battery plate production and processing, in particular to a dual-station off-line battery sheet EL detection and sorting device. Background technique

[0002] In the field of solar photovoltaic technology, in the actual production of photovoltaic modules, EL detection (electron luminescence detection) is required to determine whether there are defects. The EL detector is a testing instrument specially used for EL detection. At present, the existing equipment is an online detection device, which is tested during the production process of the battery panel. The equipment is not flexible enough, occupies the production line, is inconvenient to maintain, and affects the production capacity. Moreover, the single-line production has a low production capacity; if the old production line needs to add EL detection equipment , the line needs to be stopped for renovation, which increases the renovation cost and makes construc...
