Abstract:
A pressure device comprisinga base plate, a support plate spaced at a prescribed distance from the base plate, a first slider and a second slider; the first slider and second slider being formed so that the two can move between the base plate and the support plate in a direction orthogonal to the base plate and the support plate and are capable of relative movement with each other in that direction, a position sensor for detecting the moving position of the second slider, a first drive means for driving the first slider, a second drive means disposed on the first slider for driving the second slider, and a central processing unit which controls the first drive means and the second drive means and receives and processes position signals from the position sensor, wherein a workpiece being pressed which is placed between the second slider and the base plate is pressed until the workpiece reaches a prescribed position by moving the second slider to a prescribed position by use of the second drive means based on position signals from the position sensor, while moving the first slider and the second slider by use of the first drive means.
