Abstract

PURPOSE:To maintain the delivery of coating agent constant at all times by providing a sensor for detecting the amount of coating agent in a syringe and a controller for controlling a pressure supply valve to maintain the unit delivery of coating agent constant based on the output from the sensor. CONSTITUTION:A coating device to be employed tor securing electronic chip parts onto a printed board is provided with a sensor 50 for detecting the coating amount in a syringe 10 and a controller 57 for controlling a pressure supply valve 60 to maintain unit delivery of the coating agent constant based on the output from the sensor 50. Relation between the residual amount of adhesive in the syringe 10 and the delivery under a predetermined pressure, for example, is contained in a RAM 58. When the adhesive is fed, residual amount of adhesive in the syringe 10 is detected by a line sensor 50 through the position of a float 51, then the detected value is compared with a standard delivery at the comparing section in a CPU 57. Thereafter, pressurizing time or pressurizing force necessary for the standard delivery is calculated at the calculating section in the CPU 57 in order to control an air valve 60.
