Abstract
An apparatus for laser processing a board is provided. The apparatus for laser processing a board includes a chip, a laser, a modulating device and a focus device. The chip receives a first frequency signal to generate a second frequency signal. The laser receives the first frequency signal to emit a first laser beam. The modulating device receives the second frequency signal and the first laser beam, and adjusts the first laser beam to emit a second laser beam. The focus device focuses the second laser beam to emit a third laser beam onto the board for forming plural dots on the board.
Claims18
An apparatus for laser processing a light guide board, comprising:
- a chip directly receiving a first frequency signal and an external command both to generate a second frequency signal having a pulse width determined by the external command;
- a laser device directly receiving the first frequency signal to emit a first laser beam;
- a modulating device directly receiving the second frequency signal and the first laser beam, and adjusting the first laser beam to emit a second laser beam based on the pulse width of the second frequency;
- and
- a focus device focusing the second laser beam to emit a third laser beam onto the light guide board for forming plural dots sequentially along a horizontal path on the light guide board,
- wherein the modulating device intercepts a predetermined time section of the first laser beam based on the pulse width of the second frequency signal to generate the second laser beam.
An apparatus for laser processing a light guide board, comprising:
- a laser device receiving a first frequency signal to emit a first laser beam;
- a modulating device receiving a second frequency signal having a pulse width and the first laser beam, and adjusting the first laser beam to emit a second laser beam based on the second frequency signal, wherein the first frequency signal is a periodical signal having a positive edge trigger and the second frequency signal is generated by referring to the positive edge trigger of the first frequency signal;
- and
- a focus device focusing the second laser beam to emit a third laser beam onto the light guide board for forming plural dots of uniform appearance, radius and depth sequentially along a horizontal path on the light guide board,
- wherein the modulating device intercepts a predetermined time section of the first laser beam based on the pulse width of the second frequency signal to generate the second laser beam.
