The laser beam shape that the spacing that is open adjustment passes through the opening.
Preferably, anti-dazzling screen described in two groups passes through the reversed spiral shell of double thread that elastic slice seat is installed vertically on X, Y direction respectively
Bar, the X, Y-axis double thread counterscrew the other end one driving motor is installed respectively.
Preferably, anti-dazzling screen described in two groups respectively has two panels, and material is the copper sheet of 0.2mm thickness.
Preferably, the double thread counterscrew is installed on bottom plate by screw mandrel support seat.
Preferably, the driving motor is stepper motor, and the driving motor is fixedly installed in bottom by motor mounting plate
On plate.
Preferably, the guide rail includes guiding cushion block and cover board, and the guiding cushion block top edge is a step, the cover board
The guide rail of groove-like is formed after covering on guiding cushion block, the anti-dazzling screen is slided along guide rail.
Preferably, which further includes limit film, limit switch and L-type boat fork metal plate.
Using the technical solution of the utility model, have the advantages that

It closes, square focus spot is shaped to when round laser passes through anti-dazzling screen, and the size of hot spot and Aspect Ratio can be with anti-dazzling screens
Movement and change, obtain the hot spot of different mode, it is versatile, and spot energy distribution is uniform, edge is sharp keen, different shape
Short-circuit foreign matter once repairs success by converting hot spot, and reparation precision is higher, greatly improves remediation efficiency.
Detailed description of the invention
Fig. 1 is the utility model structure chart；
Fig. 2 is the utility model anti-dazzling screen mispairing Local map；
Fig. 3 is the utility model effect picture.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
Referring to Fig.1, the utility model provides a kind of laser beam shaping device, the bottom plate 1 including an X/Y plane and is parallel to
Bottom plate 1 and orthogonal two groups of anti-dazzling screens 201,202, anti-dazzling screen 201,202 described in two groups can be parallel to X, Y-axis side in edge respectively
To guide rail 301,302 slide switchings, adjusted by the opening spacing of each group of anti-dazzling screen 201,202 of control and pass through the opening
Laser beam shape.
Anti-dazzling screen 201,202 described in two groups is installed vertically on the double thread of X, Y direction by elastic slice seat 501,502 respectively
Counterscrew 401,402, the X, Y-axis double thread counterscrew 401,402 the other end install respectively a driving motor 701,
702。
Anti-dazzling screen 201,202 described in two groups respectively has two panels, and material is the copper sheet of 0.2mm thickness.
The double thread counterscrew 401,402 is installed on bottom plate 1 by screw mandrel support seat 601,602.
The driving motor 701,702 be stepper motor, the driving motor 701,702 by motor mounting plate 801,
802 are fixedly installed on bottom plate 1.
The guide rail 301,302 includes guiding cushion block and cover board, and the guiding cushion block top edge is a step, the cover board
The guide rail 301,302 of groove-like is formed after covering on guiding cushion block, the anti-dazzling screen 201,202 is slided along guide rail 301,302.
The laser beam shaping device further includes limit film 9, limit switch 10 and L-type boat fork metal plate 11.
The working principle of the utility model are as follows:
The rotation of driving motor 701,702 drives the double thread counterscrew 401,402 of X, Y-axis to rotate, thus the side of drive
The anti-dazzling screen 201,202 of shape opens or closure, when round laser is by being shaped to square focus spot when anti-dazzling screen 201,202,
Because anti-dazzling screen 201,202 is moved with double thread counterscrew 401,402 along X, Y direction, therefore the size and length-width ratio of hot spot
Example can also change correspondingly, and focus on operation material eventually by optical lens, minimum light spot can reach 0.8um.
The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model,
Under all utility models in the utility model are conceived, equivalent structure made based on the specification and figures of the utility model
Transformation, or directly/be used in other related technical areas indirectly and be included in the protection scope of the utility model.
