A solar cell screen printing detection system

Abstract

The invention discloses a silk screen detecting system of solar cells. The system comprises a cylinder barrel and a cylinder cover; a first oil pipe and a second oil pipe are arranged on the side surface of the cylinder barrel; a piston and a guide sleeve are arranged in the cylinder barrel; a piston rod is fixed in the piston; one end, towards the cylinder cover, of the piston rod movably penetrates through the guide sleeve and the cylinder cover, and is connected with an output head by a bolt; a resistance heating wire is arranged in the cylinder wall of the cylinder barrel; the outer side of the cylinder barrel is coated with a matched insulation layer; annular piston pads are arranged at two ends of the piston; the outer diameters of the annular piston pads are equal to the inner diameter of the cylinder barrel; and the inner diameters of the annular piston pads are gradually increased along the piston to two ends of the cylinder barrel. The system is provided with the annular piston pads; and in low-temperature environment, even if hydraulic oil generates the phenomenon of slow flowing speed and partial condensation to cause low acting force acted on the piston, a hydraulic oil pump can allow the device to normally work under the preconditions of not increasing excessive power consumption and providing higher output pressure.

Description

technical field

[0001] The invention relates to a hydraulic cylinder, in particular to a silk screen detection system for solar cells. Background technique

[0002] Solar energy refers to the thermal radiation energy of the sun. It is a renewable resource with many advantages such as large amount, harmless and universal. The history of human use of solar energy can be traced back to ancient times when people used sunlight to dry items and make food. Today, people's demand for solar energy is no longer simply to use the heat of the sun. In 1615, French engineer Cox invented the world's first solar-driven engine, which opened the history of modern solar energy utilization.

[0003] A solar panel refers to a device that directly or indirectly converts solar radiation energy into electrical energy through the photoelectric effect or photochemical effect. Solar panels are now mainly used in many fields such as transportation, communications, oil drilling platforms, street ligh...
