Problems solved by technology

However, this kind of coating production process has repeated coating every time, and there is a decrease in production efficiency, secondary pollution caused by secondary coating, increased bad appearance, film running phenomenon in the secondary alignment of the secondary feeding joint, curing loss and equipment failure. Increased energy consumption, waste of manpower and other technical problems
The equipment for this kind of coating production process is a separate coater, slitting machine, corona machine, AOI inspection machine, etc. or a combination of one or two of them. Two ovens are required to complete the secondary coating, which is costly. energy efficiency is wasted

Abstract

The invention discloses a photovoltaic module backboard integrated production line, which comprises a first coating production line, a second coating production line, a compound production line, a detection mechanism, a slitting mechanism and a winding mechanism. The invention relates to a photovoltaic module backboard integrated production line and a production method thereof, which can continuously complete corona, double-side coating, drying, cooling, compounding, slitting, testing and winding processes in a short period at a time. The coating process realizes seamless connection, and a double-roller cooling machine is used for cooling without the need of standing and cooling. A double-station online slitting machine can be used to replace the slitting blade without stopping the machine, saving the replacement time and operations of shutting down and starting up. One-step molding production is achieved, so as to greatly improve production efficiency and production yield, the degreeof automation is high, the labor cost is saved, equipment energy consumption is significantly reduced, and pollution waste in production is reduced.

Description

technical field [0001] The invention relates to the technical field of photovoltaic modules, in particular to a photovoltaic module backplane integrated production line and a production method thereof. Background technique [0002] Existing photovoltaic module backsheets include coated functional layers and main insulating layers. The coating production process is to first coat the first functional layer on the coating machine, wind up and unload to the shelf for static drying for 6 hours, and then Go to the coating machine to coat the second insulating layer, rewind and unload to the shelf for 6H, then perform high-temperature curing, and then post-processing, cutting, corona, inspection, and finally packaging and shipping. However, this kind of coating production process has repeated coating every time, and there is a decrease in production efficiency, secondary pollution caused by secondary coating, increased bad appearance, film running phenomenon in the secondary alignm...
