Solar cell chip bonding machine

Abstract

The invention discloses a solar battery welding machine, comprising a frame, a large cylinder, a small cylinder, a large cylinder pushing plate, a floating plate, a welding head guiding shaft, a guideway and a welding head; the large cylinder is fixed on the frame; the lower end of the large cylinder is connected with the large cylinder pushing plate; the end of the large cylinder pushing plate and the end of a welding head supporting crossbeam are fixedly connected with a guideway sliding block; the small cylinder is fixed on the welding head supporting crossbeam; the small cylinder pushing plate is fixed on the small cylinder; two ends of the small cylinder pushing plate are fixedly connected with a welding head guiding shaft which is connected with the floating plate by a conical surface matching pair; the welding process of the welding machine is completed by two strokes, thus avoiding the impact on the welding part caused by that the large cylinder is punched to the bottom; the welding head guiding shaft and the conical surface matching pair floating mechanism of the floating plate of the welding machine lead the welding head to be always attached to the welding parts of different feeding precisions reliably and closely, thus reducing the requirement on the welding part and the feeding mechanism precision and ensuring the welding quality.

Description

technical field [0001] The invention relates to a welding machine, in particular to a pneumatic welding machine for welding solar cells into strings. Background technique [0002] In the packaging process of flexible sheet solar cell modules, it is necessary to weld single-chip cells together, such as welding in series and parallel, which is a very important process. The quality of welding directly affects the reliability of solar cell modules. At present, major manufacturers of solar photovoltaics are based on the current limited welding equipment technology, and most of them use relatively cumbersome manual soldering irons for welding. Manual welding is labor-intensive and low in labor efficiency. At present, there are also welding machines that imitate manual welding, but this kind of welding machine has insufficient repeat positioning accuracy and has a large impact on the battery sheet, making it difficult to control the welding quality.

At present, the major manufacturers of solar photovoltaics are based on the current limited welding equipment technology, and most of them use relatively cumbersome manual soldering irons for welding. Manual welding is labor-intensive and low in labor efficiency.

At present, there are also welding machines that imitate manual welding, but this kind of welding machine has insufficient repeat positioning accuracy and has a large impact on the battery, making it difficult to control the welding quality.
