Abstract
The invention provides a method used for cleaning a sintering furnace metal mesh belt. 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 the field, be specifically related to a kind of method of cleaning the sintering furnace metal mesh belt.
Background technology
Sintering circuit is last operation that crystal silicon solar energy battery is made, and is the process that silver is starched and aluminium paste passes through the quick high-temp sintering that will print at wafer in the silkscreen process.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.Front wafer surface was placed on up on the sintering furnace metal mesh belt and enters in the sintering furnace after serigraphy was finished, at high temperature Fast Sintering.
The sintering furnace metal mesh belt is after long-term the use, and the dust such as aluminium powder that can be come off in dust, the aluminium paste cover.So need every now and then used sintering furnace metal mesh belt to be carried out cleaning.At present, be only to adopt the pure water Ultrasonic Cleaning mostly to the cleaning method of sintering furnace metal mesh belt.This kind 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 the sintering furnace metal mesh belt to clean when scavenging period is inadequate, and chip back surface aluminium paste sintering was incomplete when the aluminium powder that does not clean up on the sintering furnace metal mesh belt can cause the sintering furnace metal mesh belt to reuse, thereby affected the battery qualification rate.
Summary of the invention
Technical problem to be solved by this invention provides 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:
A kind of method of cleaning the sintering furnace metal mesh belt, the method comprises following operating procedure:
(1) sintering furnace metal mesh belt to be cleaned is placed pure water, ultrasonic cleaning 5～10min washes the dust on the sintering furnace metal mesh belt;
(2) the sintering furnace metal mesh belt is placed the ethyl acetate aqueous solution, ultrasonic cleaning 20～40min washes the aluminium powder on the sintering furnace metal mesh belt, and wherein the volume ratio of ethyl acetate and water is 1:30～45 in the ethyl acetate aqueous solution;
(3) the sintering furnace metal mesh belt is placed pure water, ultrasonic cleaning 5～10min washes ethyl acetate residual on the sintering furnace metal mesh belt;
(4) the sintering furnace metal mesh belt is dried, bake out temperature is 100～200 ℃, and drying time is 2～10min.
As preferably, the ultrasonic cleaning time is 8min in the described step (1).
As preferably, the ultrasonic cleaning time is 30min in the described step (2).
As preferably, the ethyl acetate of the ethyl acetate aqueous solution and the volume ratio of water are 1:30 in the described step (2).
As preferably, the ultrasonic cleaning time is 10min in the described step (3).
As preferably, bake out temperature is 150 ℃ in the described step (4), 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 the 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, increased equipment capacity, and can fully the aluminium powder on the sintering furnace metal mesh belt be cleaned up, Effective Raise the battery qualification rate.
