Abstract

A laser engraving machine having dual quick release mirror holders is provided. The laser engraving machine comprises a machine station, a first mirror holder and a second mirror holder. The machine station has a working platform, a rail and a first laser tube. The first mirror holder is disposed on the rail and receives the laser light emitted from the first laser tube for carrying out a laser processing on the working platform when moves back and forth on the rail. The second mirror holder is composed of a second laser tube assembled on an output module, wherein the output module has a first binding portion and a second binding portion. The first binding portion detachably attaches to the rail for the second mirror holder to move on the rail. The second binding portion detachably attaches to the first mirror holder.

Claims

1. A laser engraving machine having dual quick release mirror holders, comprising: a machine station having a working platform for a workpiece to be disposed thereon, wherein the machine station is provided with a rail mounted above the working platform, and a first laser tube for emitting a laser light along a light path; a first mirror holder disposed on the rail and receiving the laser light emitted from the first laser tube along the light path for carrying out a laser processing on the workpiece on the working platform when moves back and forth on the rail; a second mirror holder composed of a second laser tube assembled on an output module, wherein the output module have a first binding portion and a second binding portion, and the first binding portion detachably attaches to the rail for the second mirror holder to move on the rail, and the second binding portion detachably attaches to the first mirror holder to allow the second mirror holder to separately perform a laser output or synchronously perform the laser output with the first mirror holder.

2. The laser engraving machine according to claim 1, wherein a laser wavelength of the laser light of the second mirror holder is different from that of the first mirror holder.

3. The laser engraving machine according to claim 1, wherein the first binding portion of the output module is a roller set for engaging the rail and moving thereon.

4. The laser engraving machine according to claim 1, wherein the second binding portion is a joint connector, and a position of the first mirror holder corresponding to the second binding portion is disposed with a connecting interface, so as to allow the first mirror holder drives the second mirror holder to move on the rail after the joint connector connects with the connecting interface.

DETAILED DESCRIPTION OF THE INVENTION

[0017] Please refer to FIG. 1 to FIG. 5, which show an embodiment of a laser engraving machine having dual quick release mirror holders. The laser engraving machine is composed of a machine station 1, a first mirror holder 2 and a second mirror holder 3 configured on the machine station 1.

[0018] As shown in FIGS. 1 and 2, a machine station 1 has a working platform 11 for a workpiece 4 disposed thereon, and the working platform 11 is mounted a rail 12 thereon. The machine station 1 is futher configured to dispose a first laser tube 13.

[0019] The first mirror holder 2 is disposed on the rail 12, wherein the first mirror holder 12 receives the laser light from the first laser tube 13 via a light path 14 (as shown in FIG. 2) so that when the first mirror holder 2 moves on the rail 12 back and forth, the workpiece 4 is performed by a laser processing on the working platform 11.

[0020] As shown in FIGS. 3 to 5, the second mirror holder 3 is composed of a second laser tube 31 assembled on an output module 32. The laser wavelengths of the first laser tube 13 and the second laser tube 31 are different, and the wattage of the second laser tube 31 is lower than that of the first laser tube 13. The output module 32 has a first binding portion 321 and a second binding portion 322. The first binding portion 321 of the output module 32 is a roller set for engaging the rail 12 detachably. After the first binding portion 321 engages the rail, the second mirror holder 3 can move on the rail 12. The second binding portion 322 is a joint connector which can engage the first mirror holder 2 detachably. A position of the first mirror holder 2 is configured to dispose a connecting interface 21 corresponding to the second binding portion 322, so as to allow the first mirror holder 2 drives the second mirror holder 3 to move on the rail after the joint connector (the second binding portion 322) connects with the connecting interface. The second mirror holder 3 and the first mirror holder 2 perform a laser output on the working platform 11 separately or synchronously (as shown in FIG. 1).

[0021] Therefore, when implemented, the second mirror holder 3 can move on the rail 12 via the first binding portion 321 (i.e. roller set), and the second binding portion 322 is engaged with the connecting interface 21 of the first mirror holder 2. Therefore, when the laser processing operation is performed, the first mirror holder 2 is driven to move, and then the second mirror holder 3 can be moved synchronously, so as to respectively perform engraving or cutting operations with different laser wavelength outputs.

[0022] Thereby, there are following advantages in the present invention:

[0023] 1. With the design of the second mirror holder of the present invention and the second laser tube loaded on it, it can be connected with the first mirror holder in a detachable design. The design of the duel mirror holder can perform the output of different laser wavelengths separately or synchronously. There is no need to change the existing structure design of the machine to install other laser tubes or change the light paths. Two laser outputs can be performed on the rail without switching, which greatly improves work efficiency.

[0024] 2. The second mirror holder of the present invention can be connected with the first mirror holder through a simple connecting design (such as snap connection, magnetic attraction or locking, etc.). It does not need to spend too much time for the operator in the follow-up installation or maintenance, which is very convenient.

[0025] 3. Since the present invention utilizes the design of attaching a second mirror holder, the second laser tube on the second mirror holder can be replaced according to different processing requirements to achieve the laser light output of different wattages.

[0026] An embodiment of the present invention and the technical means applied are as described above. Based on the disclosure or teaching of the description, numerous variations and modifications may be derived, which are to be considered as equivalent changes of the concept of the present invention. Hence, the effectiveness generated by such variations and modifications are within the substantial spirits covered by the description and drawings, and are to be encompassed within the technical scope of the present invention.

[0027] In conclusion, based on the above disclosure, the laser engraving machine having dual quick release mirror holders of the present invention is capable of achieving expected objects of the present invention, and provides industrial applicability. Therefore, a patent application is submitted accordingly.

[0028] It should be understood that different modifications and variations could be made from the disclosures of the present invention by the people familiar in the art, which should be deemed without departing the spirit of the present invention.
