The method comprises the following operation steps of: placing the sintering furnace metal mesh belt to be cleaned in pure water, carrying out ultrasonic cleaning for 5-10 minutes, and cleaning dust on the sintering furnace metal mesh belt; placing the sintering furnace metal mesh belt in an ethyl acetate water solution, carrying out ultrasonic cleaning for 20-40 minutes; cleaning aluminium dust on the sintering furnace metal mesh belt, wherein the volume ratio of ethyl acetate to water in the ethyl acetate water solution is (1:30) to 45; and placing the sintering furnace metal mesh belt in the pure water, carrying out ultrasonic cleaning for 5-10 minutes, cleaning residual ethyl acetate on the sintering furnace metal mesh belt, and drying the sintering furnace metal mesh, wherein the drying temperature is 100-200 DEG C, and the drying time is 2-10 minutes. The method provided by the invention has the advantages that the cleaning time of the sintering furnace metal mesh belt is saved, and a cleaning effect is effectively improved.
Description
Technical field
The present invention relates to crystal silicon solar energy battery and make field, be specifically related to a kind of method of cleaning sintering furnace metal mesh belt.
Background technology
Sintering circuit is last operation that crystal silicon solar energy battery is made, and is by the process of the silver slurry printing on wafer in silkscreen process and aluminium paste process quick high-temp sintering.In silkscreen process, can be successively at wafer printed back silver slurry (back electrode), back side aluminium paste (back of the body electric field) and front side silver paste.After serigraphy completes, front wafer surface is placed on upward on sintering furnace metal mesh belt and enters in sintering furnace, at high temperature Fast Sintering.
Sintering furnace metal mesh belt is after long-term use, and the dust such as the aluminium powder that can be come off in dust, aluminium paste cover.So need carry out cleaning to sintering furnace metal mesh belt used every now and then.At present, be only to adopt pure water Ultrasonic Cleaning mostly to the cleaning method of sintering furnace metal mesh belt.This kind of method scavenging period probably needs 4 hours, and scavenging period is long, and line output is produced in impact; And it is not thorough also can to cause sintering furnace metal mesh belt to clean in the time that scavenging period is inadequate, when the aluminium powder not cleaning up on sintering furnace metal mesh belt can cause sintering furnace metal mesh belt to reuse, chip back surface aluminium paste sintering is incomplete, thereby affects battery qualification rate.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of method that can save scavenging period, improve the cleaning sintering furnace metal mesh belt of cleaning performance.
The technical solution adopted in the present invention is:
Clean a method for sintering furnace metal mesh belt, the method comprises following operating procedure:
(1) sintering furnace metal mesh belt to be cleaned is placed in to pure water, ultrasonic cleaning 5～10min, washes the dust on sintering furnace metal mesh belt;
(2) sintering furnace metal mesh belt is placed in to the ethyl acetate aqueous solution, ultrasonic cleaning 20～40min, washes the aluminium powder on sintering furnace metal mesh belt, and wherein in the ethyl acetate aqueous solution, the volume ratio of ethyl acetate and water is 1:30～45;
(3) sintering furnace metal mesh belt is placed in to pure water, ultrasonic cleaning 5～10min, washes ethyl acetate residual on sintering furnace metal mesh belt;
(4) sintering furnace metal mesh belt is dried, bake out temperature is 100～200 ℃, and drying time is 2～10min.
As preferably, in described step (1), the ultrasonic cleaning time is 8min.
As preferably, in described step (2), the ultrasonic cleaning time is 30min.
As preferably, in described step (2), the ethyl acetate of the ethyl acetate aqueous solution and the volume ratio of water are 1:30.
As preferably, in described step (3), the ultrasonic cleaning time is 10min.
As preferably, in described step (4), bake out temperature is 150 ℃, and drying time is 8min.
Compared with prior art, the present invention has following remarkable advantage and beneficial effect: with respect to the method that only adopts pure water ultrasonic cleaning, the scavenging period cleaning sintering furnace metal mesh belt about 4 hours in prior art, it is short that the present invention cleans the method scavenging period of sintering furnace metal mesh belt, ethyl acetate aqueous solution ultrasonic cleaning process makes cleaning performance good, not only effectively reduce the maintenance time of sintering furnace metal mesh belt, increase equipment capacity, and can completely the aluminium powder on sintering furnace metal mesh belt be cleaned up, effectively improve battery qualification rate.
