Adhesive droplet applicator - has dosing control as function of adhesive temp.

摘要

To apply dosed adhesive droplets of adhesive to a substrate, such as for fitting surface mounted devices to a circuit board, the temp. is taken off the adhesive in the cartridge (1) and the dosing parameters for the flow volume are taken as the pressure and/or time of pressure application as a function of the temp. At least one dosing parameter is read out from a fixed value memory (12) according to the temp. value registered by a thermal sensor (6). ADVANTAGE - The method gives a constant dosed flow of adhesive, without the complication of maintaining the adhesive temp.
