Plate protection film numerical control cutting-up equipment and cutting-up depth control method

Abstract

The numerical control cutting-up equipment for the plate protection film comprises a workbench, a transverse driving device, a longitudinal driving device and a film cutting-up machine head, the longitudinal driving device is arranged on the transverse driving device, and the film cutting-up machine head is arranged on the longitudinal driving device; the film scratching machine head comprises a voice coil motor, a bottom plate, a telescopic limiting mechanism and a small knife; the telescopic limiting mechanism is connected with the bottom plate and the small knife, and the small knife can stretch out or retract relative to the bottom plate under the limiting effect of the telescopic limiting mechanism; the voice coil motor is connected with the small knife through a telescopic limiting mechanism and used for driving the small knife to move up and down. Correspondingly, the invention further discloses a cutting depth control method for the plate protection film. By the adoption of the automatic film scratching device, automatic film scratching on the uneven workpiece surface can be achieved, the film scratching depth can be stably controlled, and the application occasion is wide.

Description

technical field [0001] The invention relates to a protective film dividing device, in particular to a numerical control cutting device and a cutting depth control method for a plate protective film. Background technique [0002] In the manufacturing process of household appliances, the appearance parts of household appliances, such as refrigerator door shells, side panels, rear panels, etc. Various types of metal-coated panels are generally used for back panels, washing machine covers, cabinets, water heater tubs, and microwave oven casings. The metal sheet coating is based on hot-dip galvanized steel sheet, galvanized steel sheet, electro-galvanized sheet, etc. After the surface chemical conversion pretreatment, one or several layers of polymer film is hot-coated on the surface, and then cooled and bonded. cured products. [0003] The coated steel plate purchased or processed for the first time is generally a whole piece of flat plate. Since the home appliance product is ...
