Film cutting method, film cutting system and film cutting equipment for coating surface of material with film

Abstract

The invention discloses a film cutting method, a film cutting system and film cutting equipment for coating the surface of a material with a film. The film cutting method comprises the following stepsthat delay time and the moving speed of a workpiece are obtained, and delay displacement is determined according to the delay time and the moving speed; theoretical displacement is determined according to target displacement and the delay displacement of the workpiece; and when the moving distance of the workpiece after the response moment is equal to the theoretical displacement, a cutting instruction is generated so as to execute film cutting operation. According to the film cutting method, the delay displacement of the workpiece in the delay time is determined, and the target displacementis corrected by utilizing the delay displacement, so that the workpiece just moves the target displacement distance from the time when the workpiece is sensed by a sensor to the time when a cutter acts, and the effects of improving the film cutting precision and reducing the damage rate of the cutter are achieved.

Description

technical field [0001] The invention relates to the technical field of mobile phone window panel processing, and more specifically, relates to a film cutting method, a film cutting system and a film cutting equipment for coating the surface of a material. Background technique [0002] In the production process of mobile phone window glass, in order to avoid damage caused by mutual friction, it is necessary to cover the upper and lower sides of the mobile phone window glass with an electrostatic film for packaging. In the lamination process, the film to be covered is a continuous 100m / roll electrostatic film, that is, one electrostatic film will cover the surfaces of multiple mobile phone window glasses at the same time, so the back-end process needs to remove the static electricity between adjacent mobile phone window glasses. Membrane cut. [0003] In the prior art, the workpiece is conveyed quickly, and when it moves to the detection area of ​​the sensor, the sensor gener...

However, in the actual control process, it takes a certain amount of time for the signal to be transmitted before the controller can receive and process it.

When the moving speed of the workpiece is high, the deviation of the stop position of the workpiece will be large, and the faster the moving speed of the workpiece, the closer the stop position of the workpiece is to the cutter, and it may even happen that the workpiece is just below the cutter when it stops. At this time, the cutting operation will cause double damage to the workpiece and the cutter, which directly affects the processing quality and production efficiency.
