At present for the glue point glue difficulty with particle.Nozzle striker injecting type point glue mode, utilize striker to hit nozzle, nozzle place liquid forms partial high pressure and then ejects glue, in the time containing solid particle in glue, metallic particles in liquid can be adsorbed on striker in the collision process of striker and nozzle, affect striker surface quality, thus impact point glue effect; Helicoidal pump formula point glue mode, utilizes screw pump rotation to carry out a glue, and in the time of glue, screw pump to an one point glue position rear motor drives a pump to rotate, and the some glue time is long.Time pressure formula point glue mode, air pressure and air pressure action time in the glue packing element of control point distribute glue, and in the glue distributing with solid particle, packing element internal gas pressure has resiliency, obtains compared with droplet difficulty, and the some glue time is long.
Summary of the invention
The present invention proposes a kind of Piezoelectric Driving point glue equipment.Utilize piezoelectric stack for power drive, the capable amplification of flexible hinge contraposition shift-in, top shoe sliding block is valve, and the glue that contains solid particle is carried out to a glue.
Guiding valve only has small part area to contact with liquid, valve did not clash into liquid in switch moment, the distribution effects of the metal pair valve in liquid does not affect, connect and cut off nozzle place glue and ambient pressure by the open and close moment of valve, in the process of guiding valve from full open to contract fully, displacement is little, have that the opening time is short, switching frequency is fast, liquid distributes short feature of time.
The present invention utilizes dual hinge structure, and first order hinge is T-shaped flexible hinge, is mainly piezoelectric stack to be produced to displacement be transformed into horizontal output amplification, and secondary hinge mainly drives top shoe to move, and slider displacement is limited.The displacement that piezoelectric stack produces is amplified and is produced lateral displacement through first order hinge and acts on the hinge of the second level, and secondary hinge drives at slide block transverse shifting, valve unlatching when top shoe centre bore and the connection of sliding block centre bore, and while staggering, valve cuts out; Secondary hinge movement drives slide block movement, and upper end of slide block supplies glue by flexible plastic pipe, and plastic tube absorbs motion and produces distortion, does not affect the proper motion of slide block.
It is upper that piezoelectric stack (4) elongation end acts on T-shaped flexible hinge (5), and it is upper that T-shaped flexible hinge (5) output withstands on flexible hinge (20), forms piezoelectric stack double-strand chain displacement structure for amplifying; Sliding block (22) is placed on base (3) circular hole, and top shoe (21) is arranged on slide block and compresses in inner sleeve (15); It is upper that top shoe (21) is placed in sliding block (22), and top shoe (21) is corresponding with sliding block (22) centre bore, forms valve body structure; Slide block compresses overcoat (18) bottom and is screwed on flexible hinge (20), compress between inner sleeve (15) and slide block compression overcoat (18) and be placed with spring (17) at slide block, press-cover screwing nut (16) is installed on the upper end of slide block compression overcoat (18), forms valve actuation hermetically-sealed construction; Band internal thread hole nut (25) is arranged on left frame (13), on the internal thread hole of band internal thread hole nut (25), screw (24) is installed, it is upper that the upper cover of screw (24) has spring (23), spring (23) other end to withstand on flexible hinge (20), forms valve restoring force structure.
Concrete, piezoelectric stack underframe 4 is screwed on base 3, piezoelectric stack displacement adjustment screw 6 is tightened on piezoelectric stack underframe 4, T-shaped flexible hinge 5 is fixed by screws on right support 7, piezoelectric stack 8 is placed in piezoelectric stack displacement adjustment screw 6, and piezoelectric stack 8 telescopic ends withstand on T-shaped flexible hinge 5; Flexible hinge 20 is arranged on base 3 by screw, by regulating piezoelectric stack displacement adjustment screw 6 that T-shaped hinge 5 bottoms are withstood on flexible hinge 20 just; Band internal thread hole nut 25 is arranged on left frame 13, and screw 24 is installed on the internal thread hole with internal thread hole nut 25, and on screw 24, cover has spring 23, spring 23 to withstand on flexible hinge 20, for flexible hinge 20 provides restoring force.
The invention has the advantages that, utilize secondary hinge to piezoelectric stack displacement amplify, secondary hinge has constraint slide block movement function simultaneously, and slide block can be moved in fixed position, simple in structure, reaction speed is fast, can fast allocation with the liquid of solid particle.

Detailed description of the invention:
With reference to accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, the present invention by syringe needle 1, syringe needle adapter 2, base 3, piezoelectric stack underframe 4, T-shaped flexible hinge 5, piezoelectric stack displacement adjustment screw 6, right frame 7, piezoelectric stack 8, enter cementing port 9, upper spider 10, pipe joint 11, plastic conduit 12, left frame 13, pipe joint 14, slide block and compress inner sleeve 15, press-cover screwing nut 16, spring 17, slide block and compress overcoat 18, O RunddichtringO 19, flexible hinge 20, top shoe 21, sliding block 22, spring 23, screw 24, band internal thread hole nut 25 and form.
Piezoelectric stack underframe 4 is screwed on base 3, piezoelectric stack displacement adjustment screw 6 is tightened on piezoelectric stack underframe 4, T-shaped flexible hinge 5 is fixed by screws on right support 7, piezoelectric stack 8 is placed in piezoelectric stack displacement adjustment screw 6, and piezoelectric stack 8 telescopic ends withstand on T-shaped flexible hinge 5; Flexible hinge 20 is arranged on base 3 by screw, by regulating piezoelectric stack displacement adjustment screw 6 that T-shaped hinge 5 bottoms are withstood on flexible hinge 20 just; Band internal thread hole nut 25 is arranged on left frame 13, and screw 24 is installed on the internal thread hole with internal thread hole nut 25, and on screw 24, cover has spring 23, and spring 23 other ends withstand on flexible hinge 20 left sides, for flexible hinge 20 provides restoring force.
Operation principle: enter into cementing port 9 with the glue of pressure.Regulating spring 23, screw 24 and piezoelectric stack displacement adjustment screw 6, make top shoe 21 to being displaced sideways, thereby with lucky separation of sliding block 22 centre bores, now valve cuts out suspension and can not continue to flow, when piezoelectric stack connects 8 while receiving high level signal, piezoelectric stack 8 extends, T-shaped flexible hinge 5 bottoms produce the lateral displacement amplifying, promoting flexible hinge 20 moves, flexible hinge 20 drives top shoe 21 to left movement, in the time that top shoe 21 overlaps with sliding block 22 center lines, flexible hinge 20 pushes up on screw 24, now top shoe 21 is connected with sliding block 22 centre bores, glue with pressure flows to syringe needle 1 place by top shoe 21 and sliding block 22, workpiece is carried out to a glue.In the time that piezoelectric stack 8 is received low level signal, piezoelectric stack 8 bounces back, and spring 23 promotes flexible hinge 20 and moves right, and top shoe 21 is separated with sliding block 22 axle center mouths, and liquid flow stops, and some glue stops.
