Motion platform control system and control method for optical detection equipment

Abstract

This application discloses a motion platform control system and control method for optical detection equipment, which relates to the field of optical detection technology, including: the motion platform control system includes a PLC master station, multiple slave stations and multiple action execution units, multiple action The execution unit is used to control the lifting of the loading ejector on which the object to be inspected is placed, to control the fixture of the optical inspection equipment, to control the movement of the object to be inspected in the X direction, and to control the movement of the optical inspection head in the YZ direction; The PC is used to run the UI interface of the display; the industrial PC is connected to the display and the PLC master station respectively; the PLC master station is connected to all slave stations. In the motion platform control system and control method of the present application, a PLC master station and a slave station are introduced into the motion platform control system, which reduces the cost of the control system and improves the stability of the control system.

Description

technical field [0001] The present application relates to the technical field of optical detection equipment control, in particular to a motion platform control system and control method for optical detection equipment. Background technique [0002] At present, the motion platforms of optical detection equipment on the market are based on industrial PCs. Due to the extremely high precision requirements of the motion platforms for optical detection, electrical components including axis control cards, axis drives controlled by axis control cards, and IO cards are mostly used. control system. Among them, the industrial PC can provide a good UI design, taking into account the motion control and logic control functions of the motion platform. At the same time, the industrial PC can also perform real-time data communication of vision and algorithms to complete the control of the entire electrical control system. [0003] However, the existing electrical control system has obvious...

Problems solved by technology

However, a variety of expansion cards are expensive, and the total number often requires more than 10 pieces. The configuration requirements for industrial PCs are also very high, which greatly increases the cost of the electrical control system.

[0005] ②Influence on the performance of industrial PCs, too many expansion cards increase the operating burden of industrial PCs, industrial PCs are prone to abnormalities such as computer blue screens, program freezes and crashes, and the stability of the electrical control system is poor

[0006] ③ The axis control card of the electrical control system needs more than 2 pieces, and the electric cylinder and the Z-axis servo drive are controlled in a pulse mode. The pulse signal cable is more than 10 meters long, which is easily interfered by the signal, and then affects the stability of the axis control. , and the construction wiring takes a long time
