Plate feeding self-adaptive control method

Abstract

The invention discloses a plate feeding self-adaptive control method. According to plate feeding, a suction cup is adopted for plate taking in a negative pressure adsorption mode; the control system comprises a laser distance measuring sensor, a negative pressure sensor, a PLC (Programmable Logic Controller) and a motion executing mechanism for driving the sucking disc to lift and horizontally transfer. The laser distance measuring sensor is used for detecting the distance between the suction cup and the plate in real time to obtain a distance detection signal; the negative pressure sensor is used for monitoring the negative pressure of the sucker in real time to obtain a negative pressure detection signal; and the PLC controls the motion execution mechanism to execute corresponding actions according to the distance detection signal and the negative pressure detection signal, and self-adaptive control over plate feeding is achieved. The plate feeding device solves the plate feeding problem that a feeding station tray cannot automatically ascend and descend due to the fact that the thickness of a plate structural part is not fixed in a self-adaptive mode, can be widely applied to actual production, improves production efficiency and reduces production cost.

Description

technical field [0001] The invention relates to a control method of an automatic control system, more specifically a method for controlling plate material feeding, which can be widely used in the machining industry to realize automatic control of plate material feeding. Background technique [0002] In the process of CNC, stamping and other processing and production, the loading and unloading work of machine tools is highly repetitive. Although it is simple, many operators are no longer willing to engage in this kind of work due to the complexity and tediousness. Therefore, more and more attention has been paid to the automatic control technology to realize the loading and unloading of workpieces, and the application of related technologies is also becoming wider and wider. [0003] The application of CNC machine tools, industrial robot manipulators and various mechatronic equipment has accelerated the development of CNC machining. In order to improve the stability of loadi...

Problems solved by technology

In order to improve the stability of loading and unloading, the automation solution can be imported into the equipment for loading and unloading of machine tools, and industrial robots can be used with a variety of automation products to form a professional machine tool loading and unloading solution, so as to accurately complete loading and unloading and residue cleaning, and improve production efficiency. The degree of automation can improve the flexibility and efficiency of operations. However, the cost of related technologies and equipment is high and cannot be widely used.

At the same time, in different applications, due to the different heights and thicknesses of the stacked products, the traditional fixed-mode loading and unloading mechanism cannot meet the actual needs of loading and unloading.
