Description
Technical field
The present invention relates to a kind of clamped-in style crystal oscillator components of monolithic piezoelectric crystal, belong to Printing techniques field.
Background technique
The present invention relates to a kind of continuous ink jet technology (Continuous Inkjet Printer) abbreviation CIJ ink jet numbering machines
The design of crystal oscillator driving structure part, specifically a kind of code spraying machine shower nozzle that can be realized generate accurate and stable ink dot separation
Device.
Continuous ink jet technology (Continuous Inkjet Printer) abbreviation CIJ ink jet numbering machine, is that one kind passes through software
Control, the equipment being identified on product using cordless.
Ink jet numbering machine at work, needs the crystal oscillator chamber line of ink marker entered under the effect of the pressure in spray head, then from
Nozzle projects.Ink is fragmented into that a string continuous, spacing is equal by the effect of the piezo-electric crystal in crystal oscillator chamber when by nozzle
And the identical ink droplet of size, one continuous line of ink marker is separated into this important work of ink dot to complete ink jet numbering machine.
At present in ink jet numbering machine manufacturing field, most of numerous ink jet numbering machines including several one line brands of the world use glue
Water connects both techniques of crystal oscillator bar to make bonding piezo-electric crystal with crystal oscillator bar or using multi-disc piezoelectric crystal stack clamping
Crystal oscillator bar assembly, both techniques are respectively present following problems:
A. the crystal oscillator bar assembly of glue bonding
(1) glue is easy to fall off to which crystal oscillator bar fails.
The crystal oscillator bar assembly bonded using glue can draw when encountering temperature change, spray head vibration and glue aging
It plays piezo-electric crystal and crystal oscillator bar is detached from the vibration of derivative crystal and passes to failure, cause the line of ink marker that cannot normally be separated into ink dot.
(2) crystal oscillator resonance point is unstable, sideslip is easy, to influence the normal separation of ink dot.
Glue to bond crystal oscillator bar assembly generally uses the epoxy glue of two-component, it generally requires to bond laggard baking oven
Solidified.Since piezo-electric crystal is made of ceramics, parameter characteristic itself has some variations before and after hot setting, this just makes
It can change that subsequent increase resonance point is needed to compensate and adjust afterwards before curing at the presetting resonance point of crystal oscillator component
This road technique, and subsequent compensation can only be carried out in small range, just can not be adjusted to original by compensating when deviation is larger
Set crystal oscillator point.
(3) bonding, mounting process are complicated, and product qualified rate is low.
B. crystal oscillator bar assembly is connected with the clamping of multi-disc piezoelectric crystal stack
(1) the crystal oscillator bar assemblies of multi-disc piezo crystals is since it is to meet coding by being superimposed the piezo-electric crystal of different number
Per a piece of piezo-electric crystal parameter in ink jet numbering machine use process different degrees of change can occur for the requirement of machine different frequency
To change, is also equivalent to parameter variation value is exaggerated more times using multi-disc superposition, this can increase the range of resonance frequency sideslip, from
And improve the failure rate of ink dot separation.
(2) the resonance frequency adjustment of the crystal oscillator bar assembly of multi-disc piezo crystals and compensation range are small, difficulty is high.Due to the structure
Changing frequency using the method for screw head cladding scolding tin, this method can only be reduced unidirectionally and cannot improve frequency,
Simultaneously because adjustment amplitude is directly proportional with the size of tin amount is mended, it is clear that in view of the size of entire crystal oscillator bar, mending tin amount will not be too
Greatly.
For various drawbacks of both the above crystal oscillator component, the present invention is clamped using monolithic piezoelectric crystal by the way of crystal oscillator bar
Crystal oscillator bar is assembled, the above problem is fundamentally solved and installation has used on a large scale.
Summary of the invention
Clamped-in style crystal oscillator component is made of eight parts: example is shown in Fig. 1, is the crystal oscillator component that resonance frequency is 88K.
Entire crystal oscillator bar assembly is bound up eight parts by lock-screw, and ink jet numbering machine at work, drives
The oscillator signal that dynamic circuit can issue assigned frequency (88K) is given to piezoelectric ceramics, and at this moment entire crystal oscillator bar assembly can be with this
Frequency carries out regular vibration axially to guarantee to make continuous line of ink marker fracture separation at point.
One pole-face of crystal oscillator bar and piezoelectric ceramics is close together, and is made into hardness and all very high plastics of dielectric strength
Two insulation sleeves two pole-faces of piezoelectric ceramics have been isolated, while the two insulation sleeves have functioned well as centralized positioning work again
With convenient for the installation of entire component.
Clump weight, which mainly plays, can adjust resonance frequency on a large scale to adapt to the configuration such as different frequency, nozzle, ink
Coding demand, example is shown in that Fig. 2 is the crystal oscillator component that resonance frequency is 125K, and 125K crystal oscillator component is free of clump weight.It can send out
It is existing, using the piezoelectric ceramics of same size and frequency, different frequencies are assembled into can be convenient by adjusting the thickness of clump weight
The crystal oscillator bar assembly of rate is used to be assembled into the ink jet numbering machine of various model specifications.
Silver soldering piece is plated to drive by insulation sleeve and the isolation of crystal oscillator bar and another pole-face of connection piezoelectric ceramics, ink jet numbering machine concussion
Dynamic signal is imported by weld tabs.The fastener as composed by lock screw, flat shim and spring shim is first is that play entire component
Locking effect, another important role are the resonance that can finely tune entire component when locking by the size of coupling mechanism force
Point.
The present invention is changed the glue bonding of previous ink jet numbering machine crystal oscillator component or is connected using the clamping of multi-disc piezoelectric crystal stack
Crystal oscillator bar mounting means improves crystalline substance with succinct, reliable, installation is rapid, debugging is convenient and adapts to wide clamping mounting means
