Drying machine of photovoltaic welding strip

Abstract

The invention discloses a drying machine of a photovoltaic welding strip. The drying machine comprises a wind washing chamber, a rack and a drying chamber, wherein a first conveyer belt is mounted at one end of the top end of the rack; a first driving motor is mounted in the first conveyer belt; the wind washing chamber is mounted on the first conveyer belt; a dust collection chamber is mounted on one side of the wind washing chamber; a sliding block is arranged on an electromagnetic slide rail; a hydraulic telescopic rod is mounted at the bottom end of the sliding block; an electromagnet is mounted at the bottom end of the hydraulic telescopic rod; and an infrared emitter is mounted in the bottom end of the electromagnet. According to the drying machine, the wind washing chamber, the first conveyer belt, a cleaning tank, the drying chamber and a second conveyer belt are mounted, the to-be-dried photovoltaic welding strip is sequentially subjected to cleaning, soaking and welding, full automation of the device is achieved, working efficiency is greatly improved, labor intensity is greatly reduced, and labor force is saved.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to a photovoltaic welding dryer. Background technique [0002] Manual welding of photovoltaic ribbons requires that the ribbons be as soft as possible. Soft ribbons will be in good contact with the cells after the soldering iron passes by. The stress generated during the welding process is very small, which can reduce the fragmentation rate. However, the tensile strength of the ribbon that is too soft will be reduced and it will be easily broken. For the automatic welding process, the ribbon can be slightly harder, which is beneficial to the straightening and pressure welding of the ribbon by the welding machine, and the ribbon that is too soft is easily deformed by machine welding, thereby reducing the yield of the product. Soldering with lead ribbon is relatively easy. Generally, you only need to choose the appropriate flux and the temperature compensation of the solderi...

Problems solved by technology

However, if the ribbon is too soft, the tensile strength will be reduced and it will be easily broken

For the automatic welding process, the welding strip can be slightly harder, which is beneficial to the straightening and pressure welding of the welding machine to the welding strip, and the too soft welding strip is easily deformed by machine welding, thereby reducing the yield of the product

It is relatively easy to solder with lead soldering tape. Generally, you only need to choose the appropriate flux and the temperature compensation of the soldering iron is enough. However, it is really troublesome to solder with lead-free soldering tape. Many manufacturers feel headaches about this.
