AI Technical Summary
During the processing of existing photovoltaic silicon wafer water plating film, the silicon wafer fixing mechanism cannot be synchronized from both sides of the silicon wafer, and cannot be placed in the center when the silicon wafer is fixed, resulting in the coating discharge nozzle not directly above the silicon wafer, affecting the coating processing efficiency.
A photovoltaic silicon wafer water plating film device is designed, which uses guide sliding of the guide tube to the movable rod, and the rotating transmission of the bidirectional screw to the transmission sleeve. Combined with the transmission conversion of the push rod, the tightening plate can tightly fix the silicon wafer from both sides of the carrier table, while the silicon wafer can be pushed to be placed in the center.
It reduces the operating steps and labor consumption required by operators to fix silicon wafers, improves the efficiency of water-plating film treatment of photovoltaic silicon wafers, and ensures the stable fixation and central placement of silicon wafers.

Abstract
Description
Technical Field
[0001] The utility model is applicable to the technical field of photovoltaic silicon slice production, and particularly relates to a photovoltaic silicon slice water film plating device. Background Art
[0002] At present, coating is to cover a layer of material film on the surface of the material by physical or chemical methods. The purpose is to change the surface characteristics of the product so that it has certain functions. Nowadays, in order to protect the surface of photovoltaic silicon wafers, water film coating is often performed on the surface.
[0003] However, when water coating is performed on the surface of photovoltaic silicon wafers, it is often necessary to fix silicon wafers of different sizes before coating. During the coating process, the silicon wafer fixing mechanism is often not only unable to adjust from both sides of the silicon wafer simultaneously, but also unable to center the silicon wafer while fixing it. The operator needs to center the silicon wafer and the fixed position again to ensure that the coating discharge nozzle is directly above the silicon wafer for coating, which affects the efficiency of water coating processing on photovoltaic silicon wafers. Therefore, we propose a photovoltaic silicon wafer water coating device. Utility Model Content

[0008] The outer surfaces of both ends of each transmission sleeve are movably sleeved with a push rod, and the top end of the side edge of the push rod is hinged to the outer side of the connection block through a rotating shaft.

[0024] In this technical solution (through Figure 1 , Figure 2 and Figure 3As shown), a servo motor 28 is fixedly mounted on the outer surface of each transmission frame 21, and the side of the servo motor 28 transmission shaft is fixedly connected to the outer side of the bidirectional screw rod 22 through a coupling, and a bidirectional screw rod 22 is rotatably mounted inside each transmission frame 21 through a bearing, and a transmission sleeve 23 is movably sleeved on the outer end surfaces of each bidirectional screw rod 22, and a guide tube 25 is transversely fixedly mounted on the middle end surface of the side of each support plate 2 away from the transmission frame 21, and a movable rod 26 is slidably installed inside each guide tube 25, and a connecting block 27 is fixedly mounted on the end surface of each movable rod 26 away from the support plate 2, and a clamping plate 29 is fixedly mounted on the end surface of each connecting block 27 away from the movable rod 26.

[0026] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), a fixing frame 3 is fixedly installed on the top side surface of the base 1, a delivery pipe 31 is fixedly installed on the top surface of the fixing frame 3, a spray pipe 32 is fixedly installed on the bottom side of the fixing frame 3, and the bottom of the delivery pipe 31 and the top of the spray pipe 32 are fixedly connected.
