Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, specifically to a laser cutting positioning platform for preventing edge chipping. Background Technology

[0002] Laser cutting is a modern processing technology that uses a high-power-density laser beam to precisely cut materials. It forms a kerf by melting, vaporizing, or burning the material and removing the slag with the help of an auxiliary gas.

[0003] Currently, when laser cutting brittle materials (such as glass, sapphire, and semiconductor wafers), edge chipping may occur. This is because the brittle material may undergo slight displacement due to vibration or other factors during processing, causing the processing path to deviate. If the processing path deviates, the laser may stray from the preset "low-stress path," leading to edge chipping. Therefore, an anti-chipping laser cutting positioning platform has been invented.

[0016] This utility model provides an anti-chipping laser cutting positioning platform. Please refer to [link / reference]. Figures 1-4 The system includes a base plate 10, with several supports on the top of the base plate 10. The supports are connected to the top of the base plate 10 via a position adjustment assembly to adjust the position of the supports. Each support has a clamping assembly for detecting the compressive force, and a detection assembly for detecting the position of the supports is provided on the side of the supports.

[0017] The position adjustment assembly includes: a first linear motor 20, a support plate 21, and a second linear motor 22; Two sets of first linear motors 20 are fixedly installed in four directions on the top of the base plate 10. The support plate 21 is fixedly installed on the top of the moving part of the first linear motor 20, and the second linear motor 22 is fixedly installed on the top of the support plate 21. The second linear motor 22 can be powered by a battery, and the battery can be installed on the support plate 21. In addition, the two sets of first linear motors 20 or the two sets of second linear motors 22 in the same direction can be connected to a controller.

[0018] The bracket includes: a first horizontal plate 30, a vertical plate 31, and a second horizontal plate 32; The first horizontal plate 30 is fixedly installed on the top of the mover seat of the second linear motor 22, the vertical plate 31 is fixedly installed on the top of the first horizontal plate 30, and the second horizontal plate 32 is fixedly installed on the top of the vertical plate 31. The first horizontal plate 30, the vertical plate 31 and the second horizontal plate 32 are arranged in a U-shape to accommodate the end of brittle material.

[0019] The clamping assembly includes: an electric push rod 40, a connecting plate 41, a first pressure sensor 42, a pressure plate 43, a second pressure sensor 44, and a limiting plate 45; The electric push rod 40 is fixedly installed on the top of the second horizontal plate 32, the connecting plate 41 is fixedly installed on the push rod of the electric push rod 40, the first pressure sensor 42 is fixedly installed on the bottom of the connecting plate 41, the pressure plate 43 is fixedly installed on the bottom of the first pressure sensor 42, the second pressure sensor 44 is fixedly installed on the inner side of the vertical plate 31, and the limiting plate 45 is fixedly installed on one side of the second pressure sensor 44. The electric push rod 40 can be powered by a battery, and the battery can be installed on the second horizontal plate 32. In addition, the electric push rod 40 can be connected to a controller.

[0021] In practical use, the specific operating steps for those skilled in the art are as follows: S1: A brittle material (such as glass, sapphire, semiconductor wafer) is placed between several supports, and the brittle material is preferably square; S2: The end of the brittle material is positioned in the support by the first linear motor 20 and the second linear motor 22. After the compressive force between the end of the brittle material and the second pressure sensor 44 reaches a preset value, the controller will stop the first linear motor 20 and the second linear motor 22. At the same time, the electric push rod 40 will cause the pressure plate 43 to compress the brittle material. After the compressive force between the brittle material and the first pressure sensor 42 reaches a preset value, the controller will stop the electric push rod 40. S3: The distance between the laser rangefinder 50 and the target plate 51 is detected by the laser rangefinder 50. When there is a deviation between the distance and the preset distance, the position of the laser rangefinder 50 is adjusted by the first linear motor 20 and the second linear motor 22 until the distance between the laser rangefinder 50 and the target plate 51 reaches the preset value. In this way, the position of the brittle material can be accurately located. S4: Perform laser cutting on the positioned brittle material, and during the cutting process, execute S3 to correct the position of the brittle material in a timely manner.
