The detailed description and technical content of the present invention are described below with reference to the drawings, but the drawings are only for reference and explanation, and are not intended to limit the creation.

Please refer to the first to fourth figures. The present invention provides a cutting device for optical glass, which mainly comprises a base 1, a moving mechanism 2, a storage table 3, a cantilever mechanism 4, and a cutter device 5. And a laser cutting device 6.

The base 1 is provided as a base for the various mechanisms and devices; the moving mechanism 2 is mounted above the base 1, and the moving mechanism 2 is mainly composed of two sets of moving members 21, 22 that move perpendicularly to each other, the two groups The members 21, 22 are moved and can generate linear movement of two or more.

The stage 3 is placed on the axial movement mechanism 2, and the optical glass 9 is provided and fixed. The stage 3 is driven by the displacement of the moving mechanism 2, and the stage 3 itself is also provided with a rotating member 31. It enables it to make a rotary motion on the moving mechanism 2.

The cantilever mechanism 4 includes an arm portion 41 and a base portion 42 connected to one end of the arm portion 41. The seat portion 42 is disposed corresponding to the movement range of the storage table 3. The tool device 5 is mounted on the seat portion 42, and includes a diamond knife 50 and a tool holder 55 for mounting and fixing the diamond knife 50. The tool holder 55 is composed of three sets of transmission members 551, 552, and 553, respectively, by different motors and Components such as slide rails are formed to enable the tool holder 55 to produce linear movement in three dimensions. The details of the diamond knife 50 are described below.

The laser cutting device 6 includes a laser tube 61 disposed in the arm portion 41 and a microscope objective 62 mounted on the seat portion 42 for using a laser generated by the laser tube 61. The light beam 611 is focused on the optical glass 9 to be processed (refer to the fifth figure).

Further, the cutting apparatus of the present invention further includes a coolant supply mechanism 7 having a water jet head 71 which is mounted on the seat portion 42 and located at a position opposite to the cutter device 5 for output The coolant is supplied to provide a laser beam 611 during the cutting process so that the optical glass 9 can be cooled and cooled.

Referring to the fifth to sixth, the cutting device can be applied to the cutting process of the optical glass. In use, the optical glass 9 to be processed is fixed by a jig mounted above the stage 3, and the transmission in the tool holder 55 is utilized. The downward movement of the member 553 causes the diamond knife 50 to approach the direction of the optical glass 9, and the movement of the moving member 22 in the moving mechanism 2 to drive the stage 3 and the optical glass 9 toward the diamond knife 50, and The cutting edge ridge 523 of the diamond blade 50 first cuts the surface of the optical glass 9; then, the optical glass 9 is cut by the laser beam 611 with the aforementioned blade mark as a guide. Further, in conjunction with the application of the coolant supply mechanism 7, the water jet head 71 outputs a cooling liquid to cool and cool the cutting position of the laser beam 611. In this way, not only the cutting precision of the optical glass and the smoothness of the cut surface can be ensured, but also the processing speed can be effectively increased to meet the demand for mass production.

Referring to Figures 7 to 10, the present invention provides a diamond knife for cutting optical glass. The diamond knife 50 mainly includes a shank portion 51 and a blade portion 52. The shank portion 51 is made of a material such as high carbon steel, and has a substantially rectangular shape. A diamond is embedded in one end of the shank portion 51 to form a blade portion 52 together with the above-mentioned material such as high carbon steel. The blade portion 52 includes all the edge ridge lines 523 formed by the intersection of the two inclined surfaces 521 and 522. The two inclined surfaces 521 and 522 are formed with an inner angle Θ1, and the inner angle Θ1 ranges from 70° to 120°. . The range of the inner angle Θ1 is preferably between 80° and 108°, and the inner angle Θ1 is preferably 104.5°. When the inner angle Θ1 is larger than 120°, it is easy to cause micro-cracking marks on the surface of the optical glass 9 and the depth of the cut is insufficient, resulting in a low yield of the product. When the inner angle Θ1 is less than 70°, the life of the diamond knife 50 is short and the use cost of the tool is increased.

Further, the blade portion 52 further includes a static point plane 524 perpendicular to the center line of the shank portion 51, the dead spot plane 524 being in contact with the end of the cutting edge ridge 523. A forward bevel Θ2 is arranged around the extension line of the static spot plane 524 and the cutting edge ridge 523. The range of the bevel angle Θ2 ranges from 30° to 60°, wherein the range of the front bevel Θ2 ranges from 38° to 52°. Between ° is preferred. When the inner angle Θ2 is larger than 60°, it is easy to cause an impact with the surface of the optical glass 9 during cutting, resulting in a shortened service life of the cutter. When the inner angle Θ2 is less than 30°, the cutting edge ridge 523 cannot be cut on the machined surface of the optical glass 9.

Further, the blade portion 52 further includes two side slopes 525 and 526 located behind the movement paths of the two inclined surfaces 521 and 522. The angles Θ3 formed by the two side slopes 525 and 526 are between 40° and 60°. . The angle Θ3 is preferably 50°. When the inner angle Θ3 is greater than 60°, it is easy to cause microcracking marks on the surface of the optical glass. When the inner angle Θ3 is less than 40°, the service life of the tool is short. Furthermore, the end points of the two side slopes 525, 526 are in contact with the static point plane 524, and a width of 0.2 to 0.4 millimeters (mm) is formed in the static point plane 524.
