Detailed description of the invention
In order to more clearly state this utility model, below in conjunction with the accompanying drawings this utility model is further described.
Refering to Fig. 1-4, the spraying shielding tooling of this utility model circuit board, including frock body 1, it is arranged on frock body
Multiple shielded areas 11 on 1, circuit board 2 is provided with multiple Jin Pen district 21, and multiple Jin Pen districts 21 are connected and form a Ge Jinpen district
Territory, and multiple shielded area 11 be connected and formed one with prohibit the suitable mask in spray region, mask passes through detent mechanism button
After being combined in taboo spray region, expose between frock body 1 and circuit board 2 and have area to be sprayed；The inside edge of mask is toward circuit
Plate 2 direction is extended with for completely cutting off taboo spray region and the protection board 12 of area to be sprayed, and encloses between mask and protection board 12
The blind area in spray region is prohibited in synthesis one sealing.
Compared with prior art, the spraying shielding tooling of circuit board of the present utility model, realize covering by detent mechanism
Cover is fastened on taboo spray region, it is ensured that accurate positioning so that mask is corresponding with the position prohibiting spray region, it is to avoid because covering not
Precisely drain spray, operating personnel is easy to operate, and effectively saves labour cost；Protection board 12 is used for completely cutting off taboo spray region and to be painted
It is coated with region, effectively prevents from spraying to prohibit spray region；Frock body 1 is one-body molded, easy to use and can repeatedly use, significantly
Save gummed paper cost；Owing to prohibiting, spray region is the most shielded is covered with effect protection, so shower nozzle simply the most back and forth sprays, and spray
Painting efficiency is high, improves more than 50% than selective spray efficiency.The spraying shielding tooling of circuit board of the present utility model has operation
Facilitate, save labour turnover, accurate positioning, reusable repeatedly and be conducive to improving the feature of spray efficiency.
In the present embodiment, multiple shielded areas 11 include the 111, second shielded area, the first shielded area 112 and the 3rd shielded area
113, multiple Jin Pen districts 21 include lead location district 211, multiple socket position district 212 and multiple screw hole lane place 213, multiple
The region that socket position district 212 is connected to form is socket region, and the region that multiple screw hole lane place 213 is connected to form is spiral shell
Silk bore region；First shielded area 111 is suitable with the size in lead location district 211, and the second shielded area 112 is fitted mutually with socket region
Join, and the 3rd shielded area 113 is suitable with screw hole region.Lead location district 211, socket position district 212 and screw hole position
The part polluted is avoided, if three is polluted by three-proofing coating, it is easy to cause insulation to lose during district 213 usually spraying three-proofing coating
Remove electric function, can effectively protect three by the 111, second shielded area, the first shielded area 112 and the 3rd shielded area 113.Certainly,
Need on circuit board 2 to be protected to be not limited to above-mentioned three, it is also possible to be that other need parts to be protected, if simply changing
The parts of protection, are simple deformation and the conversion of this case, fall in the range of this case protection.
In the present embodiment, detent mechanism is multiple locating dowels 13, and each locating dowel 13 inserts location corresponding on circuit board 2
Behind hole 22, mask is fastened on taboo spray region.Locating dowel 13 is conducive to installing/dismounting with the mode in hole 22, location, it is simple to work
Personnel's operation, and accurate corresponding good mask with prohibit the position in spray region, before spraying, locating dowel 13 only need to be inserted correspondence
Hole 22, location, after material to be sprayed solidification, only need to take out locating dowel 13 in hole 22, location, can take off this frock.
In the present embodiment, the shape in the second shielded area 113, shielded area the 112, the 3rd, socket region and screw hole region is
Strip.Shape after being connected due to the region at socket position district 212 or place, screw hole lane place 213 is usually strip, and the
Two shielded areas 112 are corresponding with socket region, and the 3rd screw hole region, territory, shielded area 113 is corresponding, therefore, and the second shielded area 112
It is strip, effectively protection socket region and screw hole region with the 3rd shielded area 113；Multiple screw hole lane place 213 are connected
The region formed is the most all strip, certainly, if the region shape at place, single screw hole lane place 213 is generally circular,
Therefore this case is not limited to the screw hole region of strip, the second shielded area, the 3rd shielded area and socket region, such as screw hole
The shape in region can also be circular, as long as the shape of the shielded area of device needing on circuit board to cover can effectively be covered, all
For simple deformation and the conversion of this case, fall in the range of this case protection.
In this case, the material of frock body 1 is silica gel material, polyurethane material, metal material, bakelite or organic conjunction
Become the one in macromolecular material.The material of frock body 1 makes this frock to repeatedly use, and easy cleaning spray
On frock body 1 after painting.The bottom of frock body 1 can be pasted last layer and be had viscosity and elastic dielectric film, and dielectric film has
Having certain thickness, and be silica gel material, dielectric film can effectively prevent sprayed on material from flowing in taboo spray region so that frock is originally
Body 1 can cement circuit board 2, also allows for taking off frock body 1.
Advantage of the present utility model is:
1) detent mechanism is passed through, it is achieved mask is fastened on taboo spray region, it is ensured that accurate positioning so that mask and taboo
The position in spray region is corresponding, it is to avoid because covering not precisely drain spray；
2) protection board 12 is used for completely cutting off taboo spray region and area to be sprayed, effectively prevents from spraying to prohibit spray region；
3) frock body 1 is one-body molded, the not reproducible use of gummed paper and this frock can repeatedly use, be greatly saved glue
Paper cost；
4) save labour cost, save more than 60% cost of labor than traditional rubberizing paper；
5) improve efficiency more than 60% than the protection of traditional rubberizing paper, improve efficiency than one connector protection cover of once mounting
More than 10%；
6) being protected due to taboo spray region, so shower nozzle simply the most back and forth sprays, spray efficiency is high, than
Selective spray efficiency improves more than 50%.
Only several specific embodiments of the present utility model disclosed above, but this utility model is not limited to this,
The changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
