Anti-oxidation device for heterojunction low-temperature welding strip

Abstract

The invention discloses an anti-oxidation device for a heterojunction low-temperature welding strip. The anti-oxidation device for the heterojunction low-temperature welding strip comprises a mountingbracket, an anti-oxidation pipe, a linear guide rail, an inlet guide wheel, an outlet guide wheel and an annealing water tank; the linear guide rail is vertically arranged on the mounting bracket; the anti-oxidation pipe is arranged on the linear guide rail; the annealing water tank is arranged below the anti-oxidation pipe; a floating part is arranged at the lower end port of the anti-oxidationpipe, so that the anti-oxidation pipe floats on water in the annealing water tank; the inlet guide wheel is arranged on the mounting bracket and located at the upper end of the anti-oxidation pipe; the outlet guide wheel is arranged in the annealing water tank; a base band is guided by the inlet guide wheel and the outlet guide wheel to pass through the anti-oxidation pipe without making contact with the inner wall; the inlet guide wheel and the outlet guide wheel are connected with a power source; and heating is performed through a base band short circuit, and a nitrogen injection port is formed in the inlet end of the anti-oxidation pipe. The floating type anti-oxidation pipe is matched with the floating part, synchronous moving along with the change of the liquid level is achieved, thelength of the anti-oxidation pipe is adjusted through a fixing sleeve at the upper end, and it is guaranteed that the base band does not make contact with air.

Description

technical field [0001] The invention relates to the field of photovoltaics, in particular to an anti-oxidation device for low-temperature heterojunction welding ribbons. Background technique [0002] In the preparation process of the photovoltaic ribbon, the base strip needs to be annealed first, and the annealing process is to heat the base strip and then enter the water for rapid cooling. During the heating process, the base strip is exposed to the air at high temperature. The baseband is not up to the production standard. SUMMARY OF THE INVENTION [0003] Aiming at the above-mentioned defects of the prior art, the main purpose of the present invention is to overcome the deficiencies of the prior art, and discloses an anti-oxidation device for a low-temperature welding ribbon of a heterojunction, including a mounting bracket, an anti-oxidation tube, a straight line Guide rail, inlet guide wheel, outlet guide wheel and annealing water tank, the linear guide rail is verti...
