Description

Technical Field

[0001] The utility model relates to the technical field of display screen cutting, and specifically to a static electricity removal device used in display screen cutting. Background Art

[0002] LCD screen laser cutting machine is used for cutting display glass of mobile phones, computers, LCD screens, etc. Laser cutting of glass substrate is a complex process of interaction between laser and material. The process includes transient heat conduction of laser moving heat source to heat the material, thermal stress generated by temperature field gradient change, and thermal stress is used to induce crack extension until fracture, thereby dividing the glass substrate. During the cutting process, the material is rapidly heated by the laser beam, and then rapidly cooled by convection and heat conduction, which will cause an imbalance in the distribution of thermal stress field inside the material, leading to uncontrollable cracks and affecting the cutting quality. Numerical simulation of thermal stress field of laser cutting plays an important role in mastering the dynamic distribution of thermal stress field in the cutting process and optimizing the cutting process.

[0003] The patent specification with announcement number CN206662556U discloses an anti-static adsorption platform device for laser cutting display screen glass. It realizes the function of removing static electricity by blowing ion gas to the operating table. It realizes automatic movement and blowing through the combination of driving device, screw, fixed block and nozzle, which ensures the cleaning efficiency, improves the stability of the product and is suitable for promotion.

[0004] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: during the use of the above device, the ionized gas is blown to the operating table to achieve the function of removing static electricity, and the automatic movement and blowing are achieved through the combination of the driving device, the screw, the fixed block and the nozzle, thereby ensuring the efficiency of the removal, but the blowing cannot effectively and completely eliminate the influence of static electricity. When the slices are cutting the LCD screen, the slices are easily subjected to friction and generate static electricity, thereby affecting the quality of the screen. Therefore, further improvement is needed. Utility Model Content
