A system and method based on positioning control of logistics equipment

Abstract

The invention discloses a system and method for positioning control of a logistics device. The system comprises a plurality of keys, a remote I / O unit, a first controller, a second wireless optical communication circuit, a barcode measuring circuit, a second controller, a servo motor and a servo motor driving circuit. According to the system and method for positioning control of the logistics device, barcodes are measured and scanned in real time by the barcode measuring circuit, and thus barcode information is obtained; the second controller determines the current position of the logistics device according to the barcode information obtained by barcode information scanning, a position signal is subjected to physical address analysis, the target position is obtained, and the position wherethe logistics device is stopped at the last time serves as the starting position; and finally, the second controller drives the servo motor through the servo motor driving circuit according to the starting position, the current position and the target position, and the logistics device is driven to move the target position, so that the logistics device and a fixing station module are accurately positioned and controlled on an assembly line, the control precision is improved, and the control precision is controlled within 1 mm.

Problems solved by technology

When the traditional logistics device is applied to the assembly line, since the fixed station modules arranged along the line are equipped with independently controlled motors and reduction mechanisms to provide power for the station to enter and exit parts, the mechanical cooperation between the logistics device and the fixed station modules is generally not considered. Power transition, so the positioning control accuracy between the logistics device and the fixed station module is not high. In addition, the current method uses a proximity switch at the stop position for direct positioning or converts the stop position into pulses to directly give the number of pulses to The servo amplifier, without further feedback positioning or re-correction measures, is in a simple relative position positioning. In this way, the general positioning control accuracy is 5-6mm deviation, so as to ensure that the product is safely and smoothly placed in the logistics device and the fixed station module. It is obvious that the existing fixed station modules equipped with independent control motors and deceleration mechanisms for positioning control not only have the problem of low positioning control accuracy, but also have long standby times and low utilization rates for motors and deceleration mechanisms, and construction The time-consuming control loop is complex, time-consuming and labor-intensive, which leaves hidden dangers to the long-term operation stability of the assembly line equipment system. More importantly, due to the large increase in the use of motors, the overall power consumption of the assembly line is relatively high
