Description

[0002] With the development of my country's photovoltaic industry, the demand for photovoltaic cells is increasing day by day, and the solar photovoltaic manufacturing industry has attracted worldwide attention. Excellent photovoltaic cells require perfect preparation technology, sophisticated manufacturing equipment and strict testing equipment to be tempered. In the existing photovoltaic cell industry testing equipment, the linear motion mode is generally a motor with a linear module and a cylinder. In the battery string EL testing equipment, there are four stations that need to be moved, the feeding position is for feeding, the detection position is for power-on photo testing, and the good film is sent to the OK position, and the bad film is sent to the NG position material box. This process also includes the up and down linear motion of the battery string.

[0003] In the existing battery string EL detection equipment, the movement of the battery string in the work station is achieved through linear modules or electric cylinders, which are essentially motor-driven linear motion. Its advantages are that it can be moved to any position and the movement is relatively stable. However, the cost of the motor drive mechanism is too high. A motor drive structure with a stroke of 200 is close to one thousand yuan. Although the cylinder is low in cost, the limitation of its movement position greatly restricts its use, and the stability of the cylinder is also relatively poor. Utility Model Content
