Abstract
The utility model discloses a positioning device for green oil exposure alignment, which is characterized by comprising two cylinders with different diameters by combining; an upper-end cylinder with a larger diameter is a cap; and a lower-end cylinder with a smaller diameter is a nail. The positioning device has the advantages of 1 simple structure and convenient manufacture, 2 capabilities of greatly reducing the times of film alignment feed adjustment, accordingly greatly improving manual alignment efficiency and reducing work difficulty by adopting the device for positioning, and 3 capability of greatly improving accuracy of exposure manual alignment as the device is in small allowance fit with a positioning hole on a PCB board.
Description
Technical field
The utility model relates to a kind of auxiliary locator that can improve pcb board green oil exposure manual alignment efficient.
Background technology
At present industry will be carried out exposure imaging to printing green oil when making the PCB green oil, reaching the purpose of image transfer, thereby will need the PAD that exposes to display.For exposure sources, industry also has the manual exposure machine of significant proportion at present, and this kind equipment is subjected to liking of PCB factory deeply because of cost is low.In operation, it need use Double-face gummed paper manual with the pattern on the film and the pcb board to together and fix, pcb board is sent into exposed then.Adopt thisly to the method for position contraposition, the precision of contraposition is subjected to employee's experience, technology and emotion influence especially, and is therefore this to the method for position operation easier is big, aligning accuracy is not high, quality is unstable and inefficiency.When being operated by a large amount of new employees, above shortcoming will be particularly outstanding.For this reason, industry presses for provides a kind of auxiliary exposure alignment device, reduces the operation easier of exposure hand contraposition, improves the precision and the efficient of manual alignment greatly, finally realizes the advantage maximization of green oil manual exposure machine, and shortcoming minimizes.
The utility model content
The purpose of this utility model is, overcomes the deficiencies in the prior art, and a kind of operation easier that can reduce the contraposition of exposure hand is provided, the auxiliary locator of the precision of raising manual alignment and the exposure manual alignment of efficient.
The technical solution adopted in the utility model is as follows:
A kind of locating device of green oil exposure aligning, the right cylinders different by two diameters combine, and the right cylinder that upper end diameter is bigger is the cap body, and the less right cylinder of lower end diameter is the nail body.
Preferably, described nail body diameter is 3.1mm, and length is 0.8mm.
Preferably, described nail body bottom margin is a lead angle, and the angle of described lead angle is 30 °.
Preferably, described cap body diameter is 7mm, thickness be 0.3mm.
Preferably, described cap body top is a lead angle, and the angle of described lead angle is 30 °.
The beneficial effects of the utility model are: 1, simple in structure, easy to make; 2, adopt this device location, can significantly reduce the number of times that contraposition advances to adjust the film, thereby improve the efficient of manual alignment greatly, reduce the difficulty of operation; 3, the pilot hole closed tolerance on this device and the pcb board cooperates, the accuracy that can improve exposure manual alignment greatly.
Description of drawings
Fig. 1 is the tangent plane structural drawing of the utility model embodiment.
Fig. 2 is the user mode synoptic diagram of the utility model embodiment.
The utility model content
Be further described below in conjunction with the auxiliary locator of accompanying drawing green oil exposure manual alignment of the present utility model.
As shown in Figure 1, a kind of auxiliary locator of green oil exposure manual alignment, it adopts stainless steel, comprise that successively cylindrical cap body 1 of being shaped as of vertical arrangement and nail body 2, two cylindrical axis overlap, its structure be it seems to "T"-shaped from sectional drawing, gross thickness is 1.5mm, wherein cap body 1 thickness a is 0.3mm, and diameter is 7mm, and the lead angle of 30 degree is led in the upper end; Following closely body 2 diameters is 3.1mm, and length is 0.8mm, makes lead angle in the bottom of nail body, and the lead angle angle is 30 degree, and the design of lead angle is intended to reduce this device and inserts the interior resistance of pcb board pilot hole, thereby improves efficiency of operation.
During operation, can be as follows with reference to the operation of concrete steps shown in the accompanying drawing 2:
1. utilize puncher to go out four diameters 3 four jiaos of the films and be 3.1mm circular hole 5;
2. this locating device is inserted in four jiaos of circular holes 5 from the front of the film 3, cap body 1 is followed closely body 2 outside interior;
3. outside cap body 1, stick the single face gummed paper, locating device is fixed on the film;
In the film 3 the insides four jiaos shown in regional 6 places stick double faced adhesive tape, be used for the film 3 is fixed on pcb board 4, stick single face glue at the two ends of two glue, this kind practice is intended to avoid when tearing the film 3, double faced adhesive tape counter being bonded on the pcb board 4 that come off;
5. at 4 four jiaos of the pcb boards diameter 3.175mm pilot hole 7 of respectively holing, circular hole 5 correspondences that this hole design attitude and the film are 3 four jiaos, size coupling;
6. according to the principle of the film 3 patterns and pcb board 4 pattern correspondences, earlier with the film 3 on one side the nail body of two locating devices be pressed in the pilot hole on the pcb board 4, again two on opposite is pressed in the pilot hole of pcb board 4, at last, with the hand film position 6 that double faced adhesive tape is housed once, the film 3 is bonded on the pcb board 4, and 3 contrapositions of the another side film are the same.Because all there is the film 3 on pcb board 4 two sides, whole as a sandwich, after the two sides contraposition is finished, pcb board 4 is sent into the manual exposure machine exposure, after exposure is finished the film 3 is torn, carry out operation next time again.
7. when Double-face gummed paper behind the certain number of times of operation is not sticking, change by above step 4 pair adhesive tape again.
For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of the utility model claim all according to technical scheme described above and design.
