Equipment for testing double sides IV and EL of cell

Abstract

The invention discloses equipment for testing double sides IV and EL of a cell. The equipment comprises a machine, a loading mechanism, a rotary transfer mechanism, a testing mechanism and an unloading mechanism, wherein the rotary transfer mechanism is fixed on the machine and comprises a four-station dividing plate and vehicles; the loading mechanism, the testing mechanism and the unloading mechanism are arranged on the machine or at the side of the machine along the rotating direction of the four-station dividing plate separately; four vehicles are connected outwards at uniform intervals along the periphery of the four-station dividing plate; the vehicles correspond to the loading mechanism, the testing mechanism and the unloading mechanism under the drive of the four-station dividing plate correspondingly; the vehicles are of a hollowed frame structure; and the testing mechanism is clamped towards the direction of the vehicles from the upper and lower sides. According to the equipment, simultaneous testing of the front and back sides of the cell can be achieved, the equipment is compact in structure, the space utilization efficiency is improved and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of solar battery testing equipment, in particular to a double-sided testing equipment for cell IV and EL. Background technique [0002] In order to ensure the working efficiency of the solar panel, it is necessary to test the battery sheet during the processing process to ensure that it has good electrical performance parameters. Testing and sorting of solar cells is an important link in the quality control of the finished solar module production process. However, the current test equipment mainly supports the testing of a single battery, that is, only one side of the battery can be tested, and the two sides of the battery cannot be tested at the same time. Therefore, in the specific implementation process, it is necessary to Manually test the other side of the cell after testing one side, the testing process is cumbersome and complicated, the testing equipment occupies a large area and the cost is high. ...

However, the current test equipment mainly supports the testing of a single battery, that is, only one side of the battery can be tested, and the two sides of the battery cannot be tested at the same time. Therefore, in the specific implementation process, it is necessary to Manually test the other side of the cell after testing one side, the testing process is cumbersome and complicated, the test equipment occupies a large area and the cost is high

[0003] In summary, there is currently no effective solution to the problem that double-sided cells cannot be tested simultaneously during the test process.
