In the packaging production process of the photovoltaic solar cell module, insulation and voltage resistance test, IV test and EL test are generally required to be carried out on the packaged cell module, three transmission units are required to be arranged in the existing automatic packaging production line respectively, and each unit is required to carry out wiring before testing on the cell module. Then the test is carried out on a special test instrument. Some tests are carried out under the condition of ultrahigh pressure, and are automatically and independently completed by a test instrument in order to avoid personal injury. Therefore, in order to meet the test requirements, before the photovoltaic solar cell module enters the test, the lead on the module needs to be inserted into the connecting clamp, so that the probe on the test instrument is pressed on the copper plate of the connecting clamp, and the auxiliary process before the test is completed.
The prior auxiliary process steps before testing are as follows: a connection clamp is mounted to a corner of the module, the clamp having a length of wire and plug for insertion into the wire plug of the module. The assembly with attached clamps is then automatically tested by the test equipment. After the test is finished, the plug on the connecting clamp and the plug on the component are pulled out, then the connecting clamp is disassembled from the component, and the component flows to the next station. Therefore, the installation of the connecting clamp, the mutual insertion of the plugs, the pulling-out of the plugs and the removal of the connecting clamp are all completed manually.

Particularly, the quality accident of low power of the components during batch production is extremely easy to generate in the IV test. The testing work is severely restricted.
In order to match with an automatic production line to realize the capacity, the test station mostly adopts a method of additionally arranging stations and increasing personnel to ensure the capacity. However, labor costs and the day rise, and the employment of a large number of manual operators will be contrary to the principle of low cost, high efficiency and high quality production.
In order to pursue high automation and unmanned production process, installation of a module junction box, removal of a lead, removal of a connecting clamp and the like are always problems to be solved in the field.
