Description

Technical Field

[0002] Film cutting is a process in the production of elevator enclosures, which involves cutting the film encapsulated on the surface of the sheet.

When the photoelectric proximity switches B and C detect the plate at the same time, it means that the X-axis positioning is completed. At this time, the Y-axis positioning drive 605 starts to move and drives the Y-axis first positioning baffle 604 to move. Three groups of photoelectric proximity switches are installed on the X-axis moving unit mounting member 204, which are used to detect the origin, left limit position and right limit position of the X-axis moving unit slide 203.

Then, the tool telescopic driving member 406 of the Y-axis first cutting unit 401 and the Y-axis second cutting unit 403 drives the cutting tool 405 to extend and act on the film, and the Y-axis moving unit servo motor 303 drives the Y-axis moving unit slide 304 to move, so that the Y-axis first cutting unit 401 and the Y-axis second cutting unit 403 move along the Y-axis to achieve film cutting in the Y-axis direction; after the film cutting in the Y-axis direction is completed, the cutting props 405 of the Y-axis first cutting unit 401 and the Y-axis second cutting unit 405 are retracted to avoid scratching the plate.

[0025] After the film cutting is completed, the X-axis positioning drive 602 contracts to reset the X-axis positioning baffle 603, and the Y-axis positioning drive 605 drives the Y-axis first positioning baffle 604 to move away from the Y-axis second positioning baffle 607. The plate positioning module 6 no longer clamps the plate. At this time, the plate conveying unit 5 continues to convey the plate that has completed the film cutting to the next process.
