Turnover equipment, turnaround method, and solar cell production line

Abstract

The invention discloses a turnover device, a turnover method and a solar battery production line, which are used for effectively integrating a conveying device and a sheet distributing device to improve the production efficiency of the solar battery production line. The turnover equipment includes: a signal acquisition device, a turnover device and a control device; the signal acquisition device is used to obtain the running position of the object to be turned over on the conveying device, and send the running position of the object to be turned over to the control device; the control device is used to stop the operation of the transfer device when it is determined that the running position of the object to be turned coincides with the designated position on the transfer device, and start the turnaround device, and the The objects to be turned around are turned around between the conveying device and the fabric sheeting device; wherein, the specified position is the position where the turning device is vertically projected on the conveying device.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a turnover device, a turnover method and a solar cell production line. Background technique [0002] The silicon-based thin film solar cell production line includes: edging equipment, cleaning equipment, laser scribing equipment, plasma enhanced chemical vapor deposition (Plasma Enhanced Chemical Vapor Deposition, PECVD) coating equipment, physical vapor deposition (Physical Vapor Deposition, PVD) coating equipment , material handling system (MaterialHandling System, MHS), etc., the silicon-based thin-film solar cells produced by it can be 5.7m in size 2 (Length 2.6m*Width 2.2m). Among them, the cleaning equipment uses transparent conductive oxide (Transparent Conductive Oxide, TCO) glass as the main substrate for cleaning. The size of the TCO glass is 5.7m 2 , after cleaning, the whole block of 5.7m 2 The TCO glass is directly sent to the PECVD equipment for coating, and ...

AI Technical Summary

Problems solved by technology

[0007] (1) The transmission device of the existing solar cell production line cannot effectively sense the lifting position of the lifting platform. When the transmission device continues to run and the lifting platform is lifted at the same time, the glass tray on the transmission device will hit the lifting platform, causing the glass tray to be scrapped. Even cause the transmission device to malfunction;

[0008] (2) When the glass tray leaves the conveying device with the rise of the lifting platform, when the sensor on the solar cell production line cannot detect the glass tray, it will judge that the glass tray is abnormal, that is, broken or lost, and the The relevant data information of the glass tray is cleared or lost, and when the glass tray is completed and the fabric is returned to the initial position of the conveyor, since the relevant data information of the glass tray has been cleared or lost, it is necessary to manually re-assign The new data information of the glass tray reduces the production efficiency of the solar cell production line, and cannot guarantee the consistency of the entire process information

[0009] To sum up, in the prior art, it is impossible to effectively integrate the conveying device and the laying device, which reduces the production efficiency of the entire solar cell production line
