Description

Technical Field

[0001] This utility model relates to the field of glass processing technology, and in particular to a glass substrate processing debris collection device. Background Technology

[0002] With the rapid development of industries such as electronic displays and photovoltaic glass, the demand for high-precision processing of glass substrates continues to grow. If the debris generated during processing (including micron-sized dust to millimeter-sized fragments) is not collected in a timely manner, it can easily lead to equipment wear and scratches on product surfaces. Currently, the industry generally uses negative pressure dust collection devices or mechanical cleaning structures for debris handling: negative pressure dust collection relies on high-power fans to maintain airflow, resulting in high energy consumption and insufficient separation efficiency for larger particles; mechanical cleaning mechanisms (such as scrapers and brushes), while simple in structure, have blind spots and require frequent manual cleaning of residual debris.

[0003] A Chinese patent with publication number CN222039148U discloses a debris collection device for a glass cutting machine, including a frame, a cutting machine body, a slide rail, a collection device housing (including a vertical plate, a falling cavity, and a crushing roller), an inclined slider, a brush, a conveyor belt, a driven roller, a driving roller, a receiving trough, and pipes. When the cutting machine is working, the collection device slides in the opposite direction along the slide rail. The brush sweeps the debris to the conveyor belt, and the debris is guided by the inclined slider to the falling cavity, where it is crushed by the crushing roller and discharged through the pipes, achieving automatic debris collection and crushing. This solution uses multiple sets of motors to drive the brush, conveyor belt, and crushing roller, resulting in high energy consumption and the inability to screen the debris.

[0004] In view of the above-mentioned related technologies, a glass substrate processing debris collection device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

The scraper 4 and the cleaning roller 3 are arranged in the orthogonal direction of the cutting table 1. The cleaning roller 3 rotates and sweeps the debris to the edge of the scraper 4. The orthogonal arrangement ensures that the debris is collected without dead corners.

The drive assembly 5 simultaneously drives the scraper 4 and the screening unit 6 to generate two-stage linkage. At the same time, the cleaning roller 3 rotates to sweep the debris into the periphery of the collection trough 10. When the rack 55 moves back and forth, it drives the scraper 4 through the guide rod 551 to push the debris around the collection trough 10 into the collection trough 10. After entering the collection frame 64, the multi-layer grading screen plate 641 uses the decreasing aperture and vibration to achieve particle size grading. The pull-out drawer 642 collects dust, and the collection frame 7 collects glass fragments.
