Abstract: The present disclosure discloses a fully-automatic device for detecting substrate size, a substrate detection line and a detecting method thereof. The fully-automatic device for detecting substrate size includes a main frame, a load plate, a conveying belt, a gate-type travelling mechanism and a laser sensor. A plurality of the load plates are fixed on the main frame, and one conveying belt is arranged between two adjacent load plates, and a travelling rail is arranged on the load plates located on both sides and along the length direction thereof, and the gate-type travelling mechanism is mounted on the travelling rail, and the laser sensor is mounted on the gate-type travelling mechanism through a third travelling mechanism. The present disclosure can automatically detect the substrate size instead of manual work, and thereby having advantages of fast detection speed and high detection accuracy.

Abstract: The present disclosure discloses a solar cell co-evaporation production line, which includes a base support transfer line, a substrate transfer line, and a master control room. The base support transfer line is provided with a base support upper line port and a base support lower line port. The substrate transfer line is connected to a co-evaporation device and is provided with a feed port and a discharge port. Both the feed port and the discharge port are connected to the base support transfer line. The master control room is used for controlling the base support transfer line and the substrate transfer line to act.

Abstract: Disclosed are a cooling water circulating system and a cooling water circulating control method. The cooling water circulating system comprises a main tank (2) disposed as a water supply, and a first return pipeline (9) allowing water in a glass edge grinding machine (1) to return to the main tank (2); the main tank (2) is communicated with the glass edge grinding machine (1) through a water supply pipeline; the cooling water circulating system further comprises a filtering mechanism which is configured to filter and collect glass powder in circulating water.

Abstract: An edging method is provided, comprising: providing an edging apparatus comprising at least one sensor configured to detect a distance from the sensor to the edge to be ground; providing a workpiece having an edge to be ground; setting a base value of the distance; detecting a variation value, the variation value is a difference between a present distance from the sensor to the edge to be ground during grinding and the base value; and regulating a grinding feed amount of the edging apparatus according to the variation value. An edging apparatus is further provided.

Abstract: The present disclosure provides a splicing mechanism for fixing a photovoltaic module and a photovoltaic curtain wall. The splicing mechanism includes a supporting bracket with a fixing groove and a sliding rail detachably mounted in the fixing groove. The sliding rail is provided with a sliding groove for mounting the photovoltaic module. A preset inclination angle is defined between the sliding groove and a bottom surface of the sliding rail. A first end of a first sliding groove coincides with a first end of the sliding rail; and a second end of the second sliding groove coincides with a second end of the sliding rail.

Abstract: This embodiment discloses a photovoltaic module unit and a photovoltaic device. The photovoltaic module unit includes: a support frame, whose side face is provided with a lapping portion; a photovoltaic module, two ends of which are lapped at the lapping portion; and load-bearing glass, bottom faces at two ends of the load-bearing glass being fixed to a top of the support frame. A preset clearance is provided between the load-bearing glass and the photovoltaic module. In the photovoltaic module unit and the photovoltaic device provided by this embodiment, the support frame is arranged to be supported on a road surface and to support the photovoltaic module, and the load-bearing glass is arranged to protect and cover the photovoltaic module. The ground photovoltaic power generation module unit and the ground photovoltaic power generation module are low in installation cost, convenient for maintenance and time-saving, and can be installed in different roadbed conditions.
