Embodiment 1
[0036] An embodiment of the present invention provides a method for chamfering a glass sheet by laser, comprising the following steps:
[0037] Carve the outline of the glass sample on the glass substrate, that is, the cutting line and the alignment mark, to form the sample to be processed;
[0038] Place the sample to be processed under the galvanometer scanning laser system, set the scanning line of the galvanometer scanning laser system to multiple sets of isomorphic scanning lines, use the camera to capture the alignment mark on the sample to be processed, and calculate the current sample According to the position coordinates obtained, the position of the scanning line is determined to ensure that the scanning line is aligned with the cutting line;
[0039] The galvanometer scanning laser system is used to scan the cutting line of the sample to be processed by multiple sets of isomorphic scanning lines to complete the chamfering. By setting the laser power, spot size, scan...
Embodiment 2
[0053] This embodiment discloses a method for laser processing a glass sheet, comprising the following steps:
[0054] Adopt the method for embodiment one to process glass sheet chamfering;
[0055] After chamfering, demoulding is carried out to obtain a processed glass cover plate. In this embodiment, the processed glass cover plate is obtained by tempering the glass for demoulding or scribing and demolding.
Embodiment 3
[0057] see figure 2 , this embodiment discloses a system for chamfering a glass sheet by laser, including a galvanometer scanning laser system, an off-axis camera 4, and a sample stage 6 for carrying a sample to be processed, and the galvanometer scanning laser system of the galvanometer scanning laser system The scanning lines are set as multiple sets of isomorphic scanning lines, and these isomorphic scanning lines are used to scan the cutting line multiple times to complete the chamfering. The off-axis camera is used to capture the alignment mark on the sample to be processed on the sample stage, and use the software The global coordinates of the current sample can be calculated to ensure that the scanning line and the cutting line are aligned, and the center of each group of isomorphic scanning lines is concentric with the Bezier cutting line without rotation. Scanning is achieved by deflecting the laser beam using a galvanometer.
[0058] Further, the galvanometer scann...
