Abstract

Disclosed herein are apparatuses for breaking a glass panel unified with a process table which break the glass panel formed with scribing lines along the scribing lines by irradiating laser beams. The apparatuses for breaking a glass panel unified with a process table to conduct breaking operations of the glass panel after scribing work of the glass panel as one body with the process table are installed on both sides of the process table included in a transfer-type cutting head laser cutting device. Each apparatus for breaking the glass panel unified with the process table comprises: breaking bars for cutting the glass panel by applying pressure to cutting sections of the glass panel; rotating devices for rotating the breaking bars by combining with both ends of the breaking bars; and a support equipped with cylinders for vertically moving the rotating devices in both sections.

Claims (21)

1. A system for breaking a glass panel formed with scribing lines, comprising:

a process table configured to receive the glass panel; and

apparatuses in communication with the process table, wherein the apparatuses comprise:

at least one support supporting a lower part of the glass panel, and oriented along the scribing lines;

at least one vertical movement device provided in an area below the glass panel and near an edge of the glass panel while being out of the scribing line; and

at least one rotating device provided on the vertical movement device and at least one breaking bar formed in oblong bar shape along the entire scribing line, cutting sections of the at least one breaking bar being formed in U-shape with an open face, one end of the U-shape being coupled to the at least one rotating device and the other end of U-shape being capable of being rotated over a upper part of the glass from a location under the glass panel by the at least one rotating device,

wherein the at least one vertical movement device moves the at least one breaking bar and the at least one rotating device vertically downwards when the other end of the U-shape of the at least one breaking bar is located over the upper part of the glass and whereby the at least one breaking bar puts pressure in a direction from the upper part of the glass to the lower part of the glass panel along the entire scribing line at breaking operation.

2. The system of claim 1 , wherein the at least one vertical movement device includes cylinders attached to both sections of the support, and wherein the at least one rotating device is mounted on upper parts of the cylinders such that both ends of each breaking bar are connected to the at least one rotating device.

3. The system of claim 1 , wherein the apparatuses further comprise a scrap unit having one side formed as an inclined surface and installed to be positioned on an outer side of the support by fixing both ends thereof to the at least one rotating device.

4. The system of claim 1 , wherein the apparatuses further comprise a plurality of linear guides for moving the at least one support, the at least one vertical movement device, and the at least one breaking bar in a direction vertical to the scribing lines.

5. The system of claim 1 , wherein the apparatuses are installed on both sides of the process table of a laser cutting device which employs a method of moving laser cutting heads.

6. The system of claim 1 , wherein a plurality of holes are formed on each side of the at least breaking bar.

7. The system of claim 6 , wherein the apparatuses further comprise a scrap unit having one side formed as an inclined surface and installed to be positioned on an outer side of the support by fixing both ends thereof to the at least one rotating device.

8. The system of claim 6 , wherein the apparatuses further comprise a plurality of linear guides for moving the at least one support, the at least one vertical movement device, and the at least one breaking bar breaking the glass along the scribing lines.

9. The system of claim 6 , wherein the apparatuses are installed on both sides of the process table of a laser cutting device which employs a method of moving laser cutting heads.

10. The system of claim 1 , wherein the apparatuses further comprise a plurality of linear guides for moving the at least one support, the at least one vertical movement device, and the at least one breaking bar breaking the glass along the scribing lines.

11. The system of claim 1 , wherein the apparatuses are installed on both sides of the process table of a laser cutting device which employs a method of moving laser cutting heads.

12. The system of claim 1 , wherein the at least one rotating device comprises:

servo motors for providing rotative power and controlling movement in accordance with the rotative power;

a plurality of pulleys for delivering the rotative power generated by the servo motors; and

belts for connecting the plurality of pulleys.
