Description

technical field [0001] The present application relates to the technical field of mechanical equipment control, for example, to a control method for an intermittent cutting machine, a control device and the intermittent cutting machine. Background technique [0002] The automatic cutting machine is a device used for the division and cutting of sheets in various industries, including electronic materials. The cutting machine does not need any molds when it is working. The operator only needs to set the corresponding parameters on the user interface and transmit the corresponding data to the cutting machine. The cutting machine can quickly cut according to the received instructions, with automation The characteristics of high degree and simple operation. [0003] The traditional electronic material cutting machine needs to discharge the cut electronic materials after the cutting is completed; some electronic materials are very expensive, and the cut waste will be thrown away d...

Problems solved by technology

[0006] However, this method requires the operator to first set multiple sets of processing length parameters according to the product specifications, and then manually calculate the total length of the set parameters, plus a certain material gap, and input it into the control system as the required sheet distance value

This method of operation has a high probability of making mistakes, and the work efficiency will be virtually reduced.

[0007] In addition, converting the rotation angle of the encoder into a straight line length will inevitably lead to calculation errors; comparing the measured length with the manually input film pitch length will cause comparison errors

The consequence of these two errors to the cutting machine is that the cutting of the material will become more and more biased. Since the error is not compensated or eliminated in the control software, after a period of time the full-cut cutter will cut to the material. cause waste

In order to avoid material cutting deviation, it is necessary to manually stop the machine and re-set the tool, and then restart the processing, the processing efficiency is relatively low

[0008] As a key length feedback device, the encoder is installed on the full-break drawing machine, which increases the difficulty of mechanical installation, and is prone to damage to the internal grating due to equipment vibration or mis-knocking, which in turn causes the entire encoder to fail and affects the entire machine. device control
