Optical mode plate spray coating operations platform.
Background technology:
Surface mounting technology, i.e. SMT, be most popular a kind of technology and technique in Electronic Assemblies industry.At present, mass
Circuit printing is all the processing using laser cutting technique to carry out SMT printing stencil, therefore the printing stencil of correspondence claims SMT mode of laser
Plate.The patent of Patent No. 201510779566.3 proposes a kind of nanometer solution for SMT laser template and automatically sprays dress
Putting, SMT laser template is placed in the work platforms being provided with vacuum absorption holes by it, utilizes camera collection SMT laser template, and
Work platforms is delivered to below the spray gun specified by structure for conveying, it is achieved automatically sprays, thus replaces spraying operation manually;
Wherein solution resettlement groove be provided with respective row fluid apertures structure on its work platforms used, and its vacuum absorption holes is also molded over work
Make the solution resettlement groove of platform, then during spraying, its solution is easily accessible in vacuum absorption holes, is easily caused absorption facility and event occurs
Barrier.
Summary of the invention:
The purpose of the present invention is aiming at the deficiency of prior art, and provides the SMT laser template of a kind of structure optimization
Spray coating operations platform, it is set up between solution resettlement groove on vacuum adsorption plate and work platforms and seals structure accordingly, it is to avoid
Spray solution enters vacuum adsorption plate, it is to avoid causes adsorbing facility and breaks down.
For achieving the above object, technical scheme is as follows:
The SMT laser template spray coating operations platform of a kind of structure optimization, including the body of work platforms, the upper surface of body
On form concave station, the center grafting of concave station be fixed with circle vaccum-suction attachement pad, it is recessed that body is exposed in the upper end of vaccum-suction attachement pad
The bottom surface of platform is also inserted with inner position ring and outer positioning ring, and inner position ring and outer positioning ring are pasted and fixed on the bottom surface of concave station,
Between inner position ring and outer positioning ring, grafting is fixed with sealing ring, and the upper surface of sealing ring forms the sealing lip of some arcs,
The top of sealing lip is positioned at the upside of vaccum-suction attachement pad upper surface.
Being fixed with detent mechanism on the two side that described body concave station is adjacent, detent mechanism includes that be fixed on body consolidates
Determining plate, fixed plate is bolted with regulation bolt, the end of regulation bolt is fixed with locating piece.
Forming several adsorption holes on described vaccum-suction attachement pad, adsorption hole is around the center of vaccum-suction attachement pad battle array ringwise
Row.
The concave station outage to connection is formed on the sidewall of the body of described work platforms.
The upper surface of described vaccum-suction attachement pad and the upper surface of inner position ring or outer positioning ring flush, and sealing ring is pasted solid
Being scheduled on inner position ring and outer positioning ring, the lower end of sealing ring is pressed against on the bottom surface of body concave station.
Sealing lip on described sealing ring is at least provided with two circles, and on sealing ring, the sealing lip top of inner ring is less than outside sealing ring
The top of the sealing lip of circle.
Described detent mechanism is distributed on the sidewall of body concave station one jiao, and the regulation bolt on detent mechanism uses Flos Mume
Hook bolt, same described detent mechanism regulates bolt and fixed plate is perpendicular.
The beneficial effects of the present invention is:
1, its simple in construction, sets up between solution resettlement groove on vacuum adsorption plate and work platforms and seals knot accordingly
Structure, it is to avoid spray solution enters vacuum adsorption plate, it is to avoid cause adsorbing facility and break down.
2, it sets up detent mechanism on work platforms simultaneously, facilitates the location of its SMT laser template.

Detailed description of the invention:
Embodiment: as shown in Fig. 1 is to 3, the SMT laser template spray coating operations platform of a kind of structure optimization, put down including work
The body 1 of platform, the upper surface of body 1 forms concave station 11, and the center grafting of concave station 11 is fixed with the vaccum-suction attachement pad of circle
2, the upper end of vaccum-suction attachement pad 2 is exposed the bottom surface of body 1 concave station 11 and is inserted with inner position ring 3 and outer positioning ring 4, inner position ring
3 and outer positioning ring 4 be pasted and fixed on the bottom surface of concave station 11, between inner position ring 3 and outer positioning ring 4, grafting is fixed with sealing ring
5, the upper surface of sealing ring 5 forms the sealing lip 51 of some arcs, and the top of sealing lip 51 is positioned at vaccum-suction attachement pad 2 upper surface
Upside.
Being fixed with detent mechanism 6 on the two side that described body 1 concave station 11 is adjacent, detent mechanism 6 includes being fixed on body 1
On fixed plate 61, fixed plate 61 is bolted with regulation bolt 62, regulation bolt 62 end be fixed with locating piece 63.
Form several adsorption holes 21 on described vaccum-suction attachement pad 2, adsorption hole 21 around the center of vaccum-suction attachement pad 2 in
Annular array.
The concave station 11 outage 12 to connection is formed on the sidewall of the body 1 of described work platforms.
The upper surface of described vaccum-suction attachement pad 2 and the upper surface of inner position ring 3 or outer positioning ring 4 flush, and sealing ring 5 glues
Patch is fixed on inner position ring 3 and outer positioning ring 4, and the lower end of sealing ring 5 is pressed against on the bottom surface of body 1 concave station 11.
Sealing lip 51 on described sealing ring 5 is at least provided with two circles, and on sealing ring 5, sealing lip 51 top of inner ring is less than close
The top of the sealing lip 51 of seal 5 outer ring.
Described detent mechanism 6 is distributed in the regulation bolt 62 on the sidewall of body 1 concave station 11 1 jiaos, on detent mechanism 6
Use wabbler bolt, same described detent mechanism 6 regulates bolt 62 and fixed plate 61 is perpendicular.
Operation principle: the present invention is the structure of SMT laser template spray coating operations pad optimization, it is predominantly in storage spraying
Readily install inner position ring 3 and outer positioning ring 4 in resettlement groove (concave station 11 on work platforms body 1), and install sealing ring
5, thus spray solution and vaccum-suction attachement pad 2 are separated, during SMT laser template absorption simultaneously, the sealing lip 51 of its sealing ring 5 is real
The best sealing effectiveness;And it sets up detent mechanism 6 at concave station 11 one jiao, regulated by regulation bolt 62, locating piece
63 can carry out setting up the benchmark of SMT laser template side, facilitate SMT laser template to lay.
