Description
Technical field
The present invention relates to the process units of a kind of battery sheet, relate in particular to the infrared control device of silver slurry milling apparatus with the silver slurry.
Background technology
A kind of thick slurry that conductive silver paste is made up of particulate, adhesive, solvent, the auxiliary agent of highly purified (99.9%) argent.It is very strict that conductive silver paste requires its component, and the height of the particle size of argent, shape and content thereof all has substantial connection to silver slurry performance.
The particulate of argent is the Main Ingredients and Appearance of conductive silver paste, and the conductive characteristic of solar cell mainly is to embody by it.The content of argent particulate in slurry is directly relevant with electric conductivity, says that in a sense the content of argent particulate is high more, is useful to the electric conductivity that improves the silver slurry, but when its content surpassed critical size concentration, its electric conductivity can not improve.General silver content is when 80～90% (weight ratios), and its electric conduction quantity is just near peak, and when silver content continuation increase, the electrical property of silver slurry will no longer improve, and resistance value is in rising trend on the contrary; When silver content is lower than 60%, the resistance variations instability of silver slurry.In concrete application process, silver-colored fraction of particle control in the silver slurry should be considered stable resistance, restricted by factors such as curing characteristics, adhesive strength, economy, too high as silver-colored fraction of particle, it is low to be bonded the probability that resin wraps, the bonding force of silver conductor descends behind the film-forming, the danger that has silver granuel to come off.So the silver content in the silver slurry suits generally 60～70%.
The size of silver particulate is relevant with the electric conductivity of silver slurry.Under the condition of identical volume, equal silver content, the particle diameter of silver-colored particulate is big more, and the contact probability between particulate is on the low side, and leaves bigger space, and is occupied by idioelectric resin, thereby the conductor particulate is formed obstruct, and electric conductivity descends.Otherwise particle diameter is tiny more, and the contact probability between particulate improves, and the electric conductivity of silver slurry improves.This shows that the particle size of silver-colored particulate is very big to the influence of the electric conductivity of silver slurry.Owing to be subjected to the influence of processing conditions and screen printing mode, should satisfy the particulate mesh by silk screen smoothly, the condition that meets silver-colored particulate processing again, the particle diameter of silver particulate requires to be controlled at 3～5 μ m, this granularity requirements only is equivalent to 1/10～1/5 of the common silk screen net of 250 orders footpath, can make electrically conductive particles smoothly by mesh, be deposited on thick and fast on the stock, constitute full conductive pattern.
At present, in silver slurry production process, being used for silver-colored milling apparatus is three-roll grinder, three rollers are installed on three-roll grinder, wherein, middle roller is fixedly mounted on the frame rotationally, and the gap between two rollers in front and back and the middle roller can be regulated, by the friction of three roller surface mutual extrusion and different linear velocities, thereby realization is to the grinding of silver slurry.Grinding roller on the existing three-roll grinder is the steel roller of hollow, and the recirculated cooling water cooling is inserted at two ends, and silver slurry to be ground adds between preliminary roller and central roll, flows out from the back roller after grinding.Grinding principle according to existing three-roll grinder will seek out desirable grinding, the rotary speed that should be reasonable in design between three rollers, also must accurately regulate the gap between three rollers.The size in roll extrusion gap has influence on extruding friction and the shearing force of roller to the silver slurry between three rollers, directly has influence on the grinding effect of silver slurry.At present, the rotating speed of three rollers from after increase in turn forward, its rotating ratio is 1: 3: 9, so just produces good grinding effect.And the gap between three rollers by about two manual pulley regulate, this regulative mode is to determine distance between two rollers by test method(s), by detecting the size of silver-colored particle in the silver slurry, reaches predetermined value for well with the diameter of silver-colored particle.Because the best between three rollers of existing three-roll grinder is ground the gap and can't once accurately be controlled, pure commissioning experience operation by the operator, specification requirement to the operator is very high, human factor is bigger to the influence of silver slurry quality, the product quality fluctuation is big, this is the greatest drawback that existing three-roll grinder exists, and it directly has influence on the quality of silver slurry.
Summary of the invention
In order to overcome existing three-roll grinder above shortcomings, the invention provides a kind of roller spacing and regulate the alarm device.Adopt this infrared induction suggestion device, the operator can make three rollers reach the best gap of grinding quickly and accurately by rotating existing adjusting handle, need not to regulate repeatedly by artificial experience.
