Stringer Flux Auxiliary Landing and Stringer

Abstract

The invention discloses a series welding machine scaling powder auxiliary receiving disc. The series welding machine scaling powder auxiliary receiving disc comprises a receiving disc body, and the receiving disc body is provided with an absorption groove and mounting portions, wherein the receiving disc body and a mechanical arm of a series welding machine are oppositely fixed through the mounting portions. The receiving disc body and the mechanical arm are oppositely fixed through the mounting portions, and the receiving disc body and the mechanical arm synchronously move and cannot affect the motion that a nozzle sprays scaling powder to a battery piece; the absorption groove is arranged to receive the scaling powder dropping from the nozzle, the scaling powder is prevented from dropping on the battery piece, and the negative effect caused by crystallization of the scaling powder on the nozzle can be reduced; the sprayed initial segment is uniform in thickness, the tolerance of the dropping phenomenon of the nozzle can be improved, the replacement period is prolonged, and the use cost is reduced; the absorption groove of the receiving disc body can avoid the sputtering problem of instant spraying of the scaling powder, the pollution to a non-spraying area of the battery piece is relieved, and product quality problems like hidden cracks in the welding process of the battery piece can be solved.

Description

technical field [0001] The invention relates to a stringer, in particular to a solder flux auxiliary connecting plate of the stringer and a stringer. Background technique [0002] As a clean energy source, solar energy is widely used. The main method of solar energy application is solar power generation. Solar panels are an indispensable and important part of solar power generation. Welding battery cells together to make large panels is an important part of the solar panel processing process. The welding process is usually completed by a stringer. During the welding process of the ribbon and the cell, in order to ensure the welding effect, it is necessary to spray flux. The flux spraying action is generally controlled by a high-frequency solenoid valve, and the spraying effect is completely controlled by the high-frequency solenoid valve. [0003] The above-mentioned stringer mainly has the following defects: [0004] (1) The residual flux at the nozzle of the solenoid va...

AI Technical Summary

Problems solved by technology

[0004] (1) The residual flux at the nozzle of the solenoid valve will crystallize, resulting in the thickness of the initial section of spraying being different;

[0005] (2) When multiple solenoid valves work at the same time, there is a certain error in their synchronization, resulting in different starting points of spraying;

[0006] (3) At the moment when the solenoid valve is turned on and starts spraying, the flux will sputter, causing pollution to the non-spraying area of ​​the cell; causing product quality problems such as hidden cracks during the welding process of the cell;

[0007] (4) After the solenoid valve works for a long time, the sealing material wears and leaks, which cannot meet the spraying accuracy, and needs to be replaced regularly, and the use cost is high
