Automatic cutting machine and cutting method thereof

Abstract

The invention discloses an automatic cutting machine and a cutting method thereof. The automatic cutting machine comprises a frame, a feeding mechanism and a cutting mechanism, the feeding mechanism and the cutting mechanism are arranged from front to back, the feeding mechanism comprises a feeding wheel and a driving motor driving the feeding wheel to rotate, the feeding wheel and the driving motor are arranged on the frame, a monitoring device which is connected with a frequency converter of the driving motor through a data transmission line is fixedly arranged on the frame in front of the cutting mechanism, and raw materials to be cut travel below the monitoring device. The monitoring device is arranged on a transferring path of the raw materials to be cut, and monitoring results are transmitted to the frequency converter of the servo motor by the aid of the data transmission line, so that the servo motor is controlled to slow down in advance and completely stops until to-be-cut lines on the raw materials to be cut reach below a cutter, and further cutting accuracy and product one-step cutting forming are achieved.

Description

technical field [0001] The invention belongs to the technical field of cutting machines, and in particular relates to an automatic cutting machine and a cutting method thereof. Background technique [0002] In the electronics industry, flexible sheet products such as insulating sheets, masking sheets, and adhesive sheets with various functional functions can be seen everywhere, and more than 95% of the products need to cut the raw material semi-finished products or finished products into sheets before processing. delivery. At present, most of the automatic cutting machines are used to cut the processed semi-finished or finished roll raw materials into the required flexible sheet products. The automatic cutting machine of the prior art is shown in the Chinese utility model patent CN202181135U, which discloses an automatic cutting machine for flexible sheet materials, including a frame, a reel support frame, a tensioning roller, a feeding mechanism, and a cutting mechanism a...

AI Technical Summary

Problems solved by technology

However, due to the inertia of the servo motor during high-speed operation, the servo motor cannot stop in time when the line to be cut on the raw material reaches the bottom of the cutter, which makes the cutting not accurate enough. As the cutting work continues, in the cutting process Accumulated tolerances will be generated in the process, and the size of the cut product is accurate to ±1mm, which cannot reach the ±0.3mm required by the customer at all. Therefore, the product needs to be cut many times to meet the accuracy requirements of the customer, resulting in waste of manpower and cost. , low production efficiency
