End.
In the syringe needle residue glue blowning installation, radium-shine calibration component 800 includes the calibration plane of reference 811, when work, passes through radium
One a reference value is stored in intelligent terminal by the laser wires that jet device is sent out, and when entanglement occurs in each radium-shine value, passes through intelligence
Terminal operation and by laser wires move this calibration plane of reference 811 on compensate, it is radium-shine when so as to ensure dispensing
Precision.Also, since syringe needle correction component 900 includes correction unit for accommodating dispensing needle head and for acquiring dispensing needle head
The acquisition elements of coordinate information, under the driving of XYZ power modules mechanism, XYZ power modules mechanism can drive dispensing needle head
It is moved to correction unit, the initial coordinate values of dispensing needle head can be acquired by acquisition elements, and the coordinate value is stored in intelligence
Energy terminal can be corrected, and according to dispensing needle head X, Y, Z when replacing syringe needle or the entanglement of dispensing path by acquisition elements
Initial coordinate values carry out opposite compensation, to ensure the coordinate value accuracy of dispensing needle head, to ensure qualification rate for dispensing glue.
In addition, the blowning installation further includes blowing lacquer disk(-sc) 100, blows lacquer disk(-sc) 100 and be equipped with and blow glue for accommodate dispensing needle head
Hole 110, when using the blowning installation, drive dispensing needle head is moved to the position for blowing glue hole 110 by XYZ power module mechanisms,
Make syringe needle be placed in blow in glue hole 110, since one end of gas passage 200 is connected to air source, other end connection blows glue hole 110, blows
When, air-flow is blowed to the dispensing needle head in glue hole 110 by air source through gas passage 200, thus (herein by the foreign matter on syringe needle
" foreign matter " includes residue glue etc.) it blows off, fraction defective for dispensing glue when to reduce production, effectively ensure qualification for dispensing glue every time
Rate improves the dispensing effect of product.
On the basis of the above embodiments, as shown in fig. 6, radium-shine calibration component 800 is arranged in the side for blowing lacquer disk(-sc) 100；
Radium-shine calibration component 800 includes radium-shine calibrating block 810, and the upper surface of radium-shine calibrating block 810 is the calibration ginseng with a step surface
Examine face 811.
When specific operation, laser wires are moved to the calibration plane of reference 811 of radium-shine calibrating block 810 by radium-shine equipment
Top measures, such as：The step surface of 0.5 ± 0.02mm as an a reference value and is stored in intelligent terminal (or software system
System) in, when entanglement occurs in each radium-shine value, the top that the calibration plane of reference 811 is moved to by software operation is mended into correction
It repays.
As shown in Figure 6 and Figure 7, syringe needle correction component 900 is arranged in the side for blowing lacquer disk(-sc) 100；Wherein, syringe needle corrects component
900 include syringe needle correcting mount 910, and correction unit is a correction hole (through-hole), and correction hole is located at the middle part of syringe needle correcting mount 910.
Wherein, acquisition elements use correlation optical fiber 920, correlation optical fiber 920 to be equipped with two groups, two groups of correlation optical fiber
920 along the circumferentially disposed of correction hole.
Please continue to refer to Fig. 6, syringe needle correction component 900 further includes guiding axis 930 and the spacing collar that can move along its axis
940, syringe needle correcting mount 910 is connected on spacing collar 940.Wherein, guiding axis 930 is connected on pedestal 600.
Please continue to refer to Fig. 6 and Fig. 7, syringe needle correcting mount 910 is in the cylindrical structure of hollow out；Spacing collar 940, which is equipped with, to be used
In the through-hole for wearing correlation optical fiber 920.
After the good radium-shine height of calibration, the device is by software operation in 910 inside correlation optical fiber 920 of syringe needle correcting mount
The initial coordinate values of dispensing needle head X, Y, Z are demarcated, if replace syringe needle or the entanglement of dispensing path, are marked by correlation optical fiber 920
Surely it is corrected, and opposite compensation is carried out according to the initial coordinate values of dispensing needle head X, Y, Z, to ensure the coordinate of dispensing needle head
It is worth accuracy.
Detailed process is：
(A) two groups of correlation optical fiber 920 can be formed " cross molded line " to penetrating light, in XYZ power modules mechanism
Under driving, XYZ power modules mechanism can drive dispensing needle head to be moved at correction hole, determine the position of the dispensing needle head here
It is set to preliminary center, at this point, dispensing needle head deviates the intersection position of " cross molded line "；
(B) first, under the driving of XYZ power modules mechanism, dispensing needle head deviates above-mentioned preliminary center, with first
Walk the center center of circle, carry out picture circle operation, drawn circle and correlation optical fiber 920 be formed by " cross molded line " altogether there are four
Contact point (or intersection point), also, four points can form a quadrangle, and the diagonal line intersection of quadrangle is point plastic pin
Head origin, at this point, the X-axis and Y-axis of dispensing needle head can determine；
(C) under the driving of XYZ power modules mechanism, dispensing needle head slowly lifts at the origin position, in correlation
It is herein the origin of Z axis when optical fiber 920 incudes dispensing needle head blackout, that is, determines the Z axis of dispensing needle head.
It should be noted that after completion dispensing needle head for the first time is associated with the XY of CCD, is associated with radium-shine Z, need to record
This primary action, record XYZ are that initial coordinate values carry out this action after converting dispensing needle head later, and XYZ is first with before
The deviation of beginning coordinate value compensates.
As shown in fig. 6, the lower section of radium-shine calibrating block 810, which is disposed with liner plate, supports and fixes frame；Wherein, radium-shine calibration
Block 810 supports and fixes frame by liner plate and is connected on pedestal 600.
Wherein, a kind of dispensing method using above-mentioned syringe needle residue glue blowning installation, includes the following steps：
(A) radium-shine height is demarcated on the calibration plane of reference 811 by intelligent terminal and radium-shine equipment, and the plane of reference will be demarcated
811 are used as an a reference value, are stored in intelligent terminal；
(B) X, Y, Z initial coordinate values of the dispensing needle head in correction unit are demarcated by intelligent terminal and acquisition elements；
(C) debugging dispensing needle head is blowing the position point that residue glue is removed in glue hole 110.
