Embodiment
The device of embodiment one, a kind of digital pneumatic regulating sheet adhesive machine pick-up head pressure of the present invention as shown in Figure 1 has pick-up head, oil mist separator 27 and electricity-gas proportioning valve 26, and the automatically controlled input of electricity-gas proportioning valve connects with computer 25.Pick-up head (referring to Fig. 2, Fig. 3, Fig. 4, Fig. 5) have fixed station 4, with the spline housing 5 splined shaft suction pipe 2 movingly of fixed station, compression spring 3 is arranged between splined shaft suction pipe and the fixed station, fixed station also is being provided with cylinder block 9 and supporting piston 13 with the coaxial position of splined shaft suction pipe, and piston is fixedlyed connected with the splined shaft suction pipe.The compressed air cell of cylinder has air inlet, air inlet is communicated with compressed-air actuated source of the gas by air inlet pipeline, air inlet pipeline also is being provided with oil mist separator 27 and electricity-gas proportioning valve 26, the automatically controlled input of electricity-gas proportioning valve connects with computer 25, realize the air pressure in the computer-controlled cylinder block and the equilibrant force of piston and compression spring, thereby guarantee the splined shaft suction pipe of pick-up head and the pressure that suction port presses down chip adhesive.
The device of embodiment two, a kind of digital pneumatic regulating sheet adhesive machine pick-up head pressure of the present invention, as Fig. 1,2, shown in.By 2. splined shaft suction pipes, 3. balancing spring, 4. fixed station, 5. spline housing, 6. bearing, 7. the axial limiting piece, 8. lining, 9. cylinder block, 10. flange lining, 11. rotary stopper pieces, 12. bearings, 13. pistons have been formed the pick-up head that has air rammer.The splined shaft suction pipe all is mounted in suction pipe top with the parts of upper part.The flange lining is installed in the cylinder block.Piston is fixed on the splined shaft suction pipe by jackscrew.Piston 13 can rotate in flange lining 10 and move up and down, lining 8 is pressed in 9 times holes of cylinder block, stop compressed air to be revealed, the flange of flange lining 10 covers the last hole of cylinder block 9, when compressed air enters in the cylinder block 9 from pipe joint 18, meeting jack-up piston, and piston drives the absorption bar motion that the splined shaft suction pipe forms.The compressed air cell of cylinder is communicated with compressed air source by pipeline, and pipeline one end is connected with the interface of cylinder block 9, and the other end is connected with compressed gas source.Pipeline also is provided with oil mist separator and electricity-gas proportioning valve, and the automatically controlled input of electricity-gas proportioning valve connects with computer.Splined shaft suction pipe upper end and gas path joint socket, gas path joint is by pipe joint and air-breathing soft pipe connection.When pressing down, in splined shaft suction pipe 2 screens portions suction pipe and suction port are applied downward power by balancing spring by basic shell and fixed station 4 drive pick-up heads.At this moment, by computer control electricity-gas proportioning valve, control compressed air enters the pressure of cylinder block 9 driven plunger and the displacement movement of piston, controls the pressure that balancing spring presses down the splined shaft suction pipe, just can reach the downward pressure of control suction port.Even the performance index at the use spring change, because the compressed air require and the pressure of computer control electricity-gas proportioning valve output are certain, just the pressure that can keep balancing spring that the splined shaft suction pipe is pressed down is certain.In conjunction with computer system, just realized Digital Control like this, guaranteed that effectively the suction port of splined shaft suction pipe lower end presses down the pressure of chip.
