Description
Technical field
The utility model is related to printed-board technology field, particularly a kind of contraposition caliberating device for exposing inner plating
And apply its exposure machine.
Background technology
Exposure machine is generally used during current industrial circle manufacture circuit board, can be used without any before being produced for inner plating
In the hole of mark or pattern, the method that traditional PCB internal layer manufacture crafts are taken is to expose glue first by the two sides of circuit board
Piece is aligned, and then inner layer circuit board is clipped in the middle of two films, and two sides is exposed processing simultaneously；But laser straight is delivered a child
Equipment is produced without using the digital print pattern shape of film, its alignment is by extracting in hole or pattern image on circuit board
Heart coordinate is matched with graph theory coordinate, and the operation such as translation is then zoomed in and out to figure by the data processing of figure,
Most theoretical diagram shape is accurately printed onto on circuit board at last.
Chinese patent literature CN104407502A discloses a kind of laser direct imaging equipment production non-porous circuit board of internal layer
Method, in the document, position alignment of inner layer plates is marked and imaging sensor is arranged at the same side of sheet frame, when inner plating is aligned, energy
Enough ensure the contraposition crawl of X-direction, but it cannot be guaranteed that precision is consistent with X-direction precision in the Y direction, it is impossible to ensure circuit board
XY directions harmomegathus value is consistent.
Utility model content
To solve above technical problem, the utility model devises a kind of contraposition caliberating device for exposing inner plating, can
Ensure that XY directions harmomegathus value is consistent when inner plating exposes.
The utility model adopts the following technical scheme that realization：
A kind of contraposition caliberating device for exposing inner plating, it is characterised in that including platform and exposure caliberating device is described flat
Platform surface is provided with mounting hole, and the exposure caliberating device is installed in mounting hole, and the exposure caliberating device includes two groups,
The edge that caliberating device is exposed described in two groups respectively close to platform arbitrary neighborhood is set.
Preferably, caliberating device is exposed described in every group and includes at least one.
Preferably, caliberating device is exposed described in one of which and includes at least two.
Preferably, covered with exposure figure film on the camera lens of the exposure caliberating device.
The contraposition caliberating device of the exposure inner plating of the utility model design, is divided into two groups by exposure caliberating device and is installed on
In platform, two groups of exposure caliberating devices are set respectively close to two edges of platform arbitrary neighborhood, are met and are divided on XY directions
Not can exposure aligning requirement, it is ensured that the uniformity of exposure figure harmomegathus value on XY directions, improve exposure demarcation essence
Degree.
The utility model have also been devised the exposure machine using above-mentioned demarcation alignment device, be specially：
A kind of exposure machine, including any of the above-described described contraposition caliberating device, contraposition harvester, direct write exposure device,
The stage+module is on moving track, and the direct write exposure device is installed on the top of platform with the contraposition harvester.

Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain
The utility model, is not used to limit the utility model.
It is exposure image system of the present utility model such as Fig. 1, wherein the contraposition caliberating device of exposure inner plating includes platform
1, two groups of exposure caliberating devices 21 and 22 are respectively arranged in the adjacent two sheet frame regions 11 and 12 of platform 1.It is additionally provided with direct write
Exposure device 3 and contraposition harvester 41,42, wherein direct write exposure device 3 fill 41,42 with contraposition collection and are arranged at the upper of platform
Side.
In the present embodiment, the exposure caliberating device 21 in sheet frame region 11 is set to 6, the exposure demarcation in sheet frame region 12
Device 22 is set to 4, and sheet frame region can set multiple exposure caliberating devices, can adapt to different size of inner plating and carries out
Exposure demarcation.
Such as Fig. 2, in actual exposure demarcation, inner plating 5 is positioned over the surface of platform 1, using exposing caliberating device to it
Carry out the demarcation of loci.While A face figures are exposed, on B faces in the region 11 to a point is demarcated as, in area
It is two points in domain 12, three exposure calibration points establish inner plating loci in the x-direction and the z-direction.Such as Fig. 3, work as A
After the completion of the graph exposure of face, inner plating upset carries out needing to carry out contraposition collection before graph exposure to the B faces of inner plating.It is right
Position harvester 42 and 41 captures loci in the x-direction and the z-direction respectively, it is ensured that harmomegathus value one is exposed on XY directions
Cause.
Covered with exposure figure film on the above-mentioned camera lens for using exposure caliberating device, wherein the figure for exposing demarcation can be with
For various figures, such as filled circles, hollow ring, cross or other forms, or many dot patterns, the present embodiment is
5 marker graphics.
It is described above, only the utility model preferably embodiment, but protection domain of the present utility model is not
This is confined to, any one skilled in the art can readily occur in the technical scope that the utility model is disclosed
Change or replacement, should all cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should
It is defined by scope of the claims.
