One of standby key index.There are many influence factor of internal layer alignment precision, such as the positioning accuracy of platform, the processing essence of alignment cameras
Degree, the precision and alignment device of alignment algorithm processing overleaf expose the precision of MARK.Currently used internal layer alignment dress
In setting, light hole is to be ensured that circular degree is a very difficult thing using the method for mechanical processing, such processing circular hole, carried
The deviation of the centre coordinate taken will be very big, reduces internal layer alignment precision.
Utility model content
The purpose of this utility model is to provide a kind of internal layer alignment devices for laser direct imaging equipment, improve
Alignment precision and stability improve the performance of equipment, improve the alignment precision of processing inner plating, improve production
Yield.
To achieve the above object, the utility model uses following technical scheme：
A kind of internal layer alignment device for laser direct imaging equipment, including mounting base, in the inside of the mounting base
Sky is equipped with light source in the upside of the light source base that is internally provided with of mounting base, the light source base, is set in the mounting base above light source
There are lens, the top of the mounting base to be equipped with trepanning corresponding with the lens, the outside of the trepanning is equipped with transparent glass
The middle part of piece, the transparent glass piece is equipped with light transmission circular hole, is the region of photo-etching machine exposal on the outside of light transmission circular hole.
As a further improvement of the above technical scheme：
The lens are fixed on the inside of the mounting base by trim ring.
The light source base is fixedly connected by screw with mounting base, and the light source is by being fixedly welded on light source base.
The light source is ultraviolet light.
As shown from the above technical solution, the internal layer described in the utility model for laser direct imaging equipment is directed at dress
It sets, substantially increases the yield of PCB inner platings production, it is simple in structure, by modularized design and installation, greatly improve peace
Dress and the convenience safeguarded.

As shown in figure 3, when specifically used, the internal layer alignment device for laser direct imaging equipment of the present embodiment is installed
On sucker 7, general internal layer pcb board needs two sides to expose, and first exposure front exposes the back side again, and the figure of face exposure is wanted
It is corresponding with the figure at the back side, as shown, internal layer alignment device PCB expose front when, by mounting base 1 PCB's
The back side marks, and after turnover panel, the position of the label of mounting base 1 is found by alignment cameras, then pass through inside alignment methods and rotation
Turn, harmomegathus means the figure at the back side is matched, by internal layer alignment device, the back side explosion figure and front description it is fine
Aligned.
Internal layer alignment device 10 is mounted on the sucker 7 of equipment, and the opposite of sucker is equipped with alignment device to corresponding phase
Machine 8.General internal layer pcb board needs two sides to expose, and exposes the positive post-exposure back side, and the figure of face exposure will be with the back side
Figure needs on corresponding.Internal layer alignment device passes through mounting base 1 when PCB exposes front（IMARK devices）PCB's
The back side marks.After turnover panel, the position of IMARK labels is found by alignment cameras 6, then passes through internal layer alignment algorithm.Pass through
Rotation, the means such as harmomegathus match the figure at the back side.Pass through internal layer alignment device, the figure and front description of back-exposure
It is aligned well.
Embodiment described above is only that preferred embodiments of the present invention are described, not to this practicality
Novel range is defined, and under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are to this
The various modifications and improvement that the technical solution of utility model is made should all fall into the protection of the utility model claims book determination
In range.
