Abstract

To provide a head drive device and method capable of discharging a required amount of viscous material from a head having a pressure generating element such as a piezoelectric element, a droplet discharge device having the head drive device, a head driver program, and a manufacturing process One of them is a device manufacturing method having a step of ejecting the viscous body using this method. The driving signal (COM) is a signal applied to a pressure generating element such as a piezoelectric element provided on the head. Furthermore, the clock signal (CLK2) is a signal supplied to a drive signal generation circuit that generates a drive signal (COM), and the drive signal generation circuit generates the drive signal (COM) in synchronization with the clock signal (CLK2). The present invention changes the rate of change of the voltage value per unit time of the drive signal (COM) by changing the frequency of the clock signal (CLK2) in accordance with the rate of deformation of the pressure generating element per unit time.

Problems solved by technology

As mentioned above, the conventional nozzle driving device is designed to vibrate the piezoelectric element at high speed, and the time required for rising or falling can only be set to about 102.4 μs at the longest, so it is impossible to simply drive the nozzle for general household use. The problem that the device is used as a head drive device for a droplet discharge device that discharges a high-viscosity viscous body
