Description
Technical field
The utility model is related to a kind of single sweep drive shaft and may move polygon prism light path direct write equipment, belongs to direct write exposure skill
Art field.
Background technology
PCB (printed circuit board (PCB)) is the supporter of electronic component, while being also the carrier of electronic component electrical connection.
Common PCB production equipments have traditional exposure machine, polygon prism structure laser direct-writing exposure machine, the exposure of DMD structures laser direct-writing
Machine etc..Image directly can be imaged by laser direct-writing exposure machine on pcb board, relative to traditional exposure machine, it is not necessary to use
The film, the image of formation is apparent.
With functional requirement more and more higher of the market to pcb board, pcb board also becomes to become increasingly complex, and system compatibility is got over
It is high, it is sometimes necessary to size very big substrate, still, 48 inches of super large plate is more than for size, is not had also in the prior art
Can be with the technology and equipment of high-quality processing.Traditional exposure machine can produce super large plate, but its machining accuracy is poor, does not reach
The requirement of high density, thin space.
Circuit board full-size (610 × 530) that current laser direct writing equipment can expose, with the size of circuit board
Increase, it will cause contour size of the unit(s) to become big, influence splicing precision and aligning accuracy cause yields to decline.
If laser direct-writing exposure machine is prepared by increasing the method for the size that sucker can expose, due to required vacuum
Sucker size is that, than larger, sometimes more than 55 inches, there are the following problems for meeting：(1) when the pcb board actual size exposed
When smaller, and sucker structure supports larger vacuum range, and the region for being not covered with plank can produce gas leakage, and influence is inhaled
Absorption of the disk to substrate；(2) tilted due to might have corner during substrate transport, if pull of vacuum is not enough, sucker can not
Plank is inhaled flat, influences whether to expose the quality of pcb board, substrate can be caused to scrap.To solve this problem, current method has
Three kinds：
Method one：Directly ignore the problem, but can require very high to client factory pcb board, plank usually, can not come back and forth
Return and plank is bent manually, have a strong impact on production efficiency.
Method two：For various sizes of plank, different sucker backing plates are designed.The hole covering model of vacuum is inhaled on backing plate
Enclose, it is in the same size with plank.This method is simple, and operation is somewhat bothered, but when producing 55 inches of plank, it is necessary to change
55 inches of backing plate, difficulty is multiplied, and changes the time of backing plate, can increase by 150%~200%, have a strong impact on production efficiency.
Method three：Do not covered for plank and vacuumize region, blocked with article, conventional is to cut the used film.
This method very economical material benefit, but it is pretty troublesome, and different size of pcb board is, it is necessary to the film be cut into different sizes, for a long time
Get off, the film accumulation after the cutting of board producing region can be caused, the size that finding needs also is bothered.
As can be seen here, generally suitably given up using the replacing suitable sucker of size or searching shape size in the prior art
Abandon the film to block the mode of air leakage point, can all substantially reduce production efficiency.
To sum up, current polygon prism light path direct write equipment there are problems that super large plate, vacuum cup can not be produced urgently
It is to be solved.
