Application of Solidot XB6 series EtherCAT slice I/O module in photovoltaic velvet feeding and discharging equipment

Photovoltaic

The photovoltaic industry is a new energy industry encouraged by the state, and it is also a component of strategic emerging industries supported by the state. For the photovoltaic industry, the country has issued a number of industry-specific support policies to encourage the development of the photovoltaic industry while establishing and improving industry regulations, creating a good policy environment for the development of the photovoltaic industry.

The wet manufacturing process is the beginning of the solar cell production process. The original cell sheet obtained from the superior manufacturer or superior raw material factory will start its new career here, as the beginning of the life of the cell. Wet processes such as texturing, is one of the most difficult processes to control in the entire production process. The main function of the texturing machine is to remove the mechanical damage layer, increase the surface area of the cell, reduce the reflectivity of the cell surface, and clean the surface oil and impurities. This case will focus on the application of XB6 series EtherCAT protocol slice I/O modules of SOLIDOT Technology in photovoltaic texturing loading and unloading machine equipment.

Photovoltaic texturing loading and unloading machine equipment process description

The raw materials are manually loaded into the designated position in the loading area, and then the AGV car automatically picks up the materials and transports them to the texturing loading machine. The loading machine transports the materials to the texturing machine for professional processing such as removing the mechanical damage layer. After the operation is completed, the materials is discharged through the texturing unloading machine and transported to the corresponding position by the AGV car. The main body of the loading and unloading machine is composed of conveyor belts, suction cups, flower baskets and other mechanisms. It has a large number of cylinders, photoelectric switches, proximity switches and other signals. It is characterized by a large number of signals and scattered installation locations. Therefore, the XB6 series slice I/O module is used to solve it. During the operation of the equipment, all sensor detection signals are collected by the XB6-3200A module, the actuator signals such as cylinders are controlled by the XB6-0032A module, and the servo motor controls the conveyor belt operation and transportation. The texturing loading machine uses 5 sets of XB6-EC series modules, and the texturing unloading machine uses 1 set of XB6-EC modules.
