Abstract

The present invention provides a control system and method for a liquid crystal panel hoist, the system comprising: a PLC controller connected to a barcode reader for outputting control according to the position information of the barcode tape read by the barcode reader signal; the drive motor is used to drive the lifting of the car of the hoist; the frequency converter is connected to the PLC controller and the drive motor respectively, and is used to control the drive motor according to the control signal of the PLC controller; the servo motor is used to drive Lifting and lowering of the transport line in the car; the servo driver is connected to the PLC controller and the servo motor respectively, and is used to drive the servo motor to rotate according to the control signal of the PLC controller. The present invention realizes the lifting and lowering of the transportation line in the car through the servo motor, which solves the problem that the deformation of the steel wire rope causes the deviation of the height of the transportation line in the car and the external transportation line, and makes the position control accuracy of the transportation line in the car Control within 0.5mm.

Description

technical field [0001] The invention relates to the technical field of hoists, in particular to a precise positioning control system and method for a hoist with a liquid crystal panel. Background technique [0002] The hoist is a mechanical conveying device with a fixed device, which can realize vertical reciprocating conveying of materials up and down. This type of LCD panel hoist has the characteristics of advanced control, reliable performance, and high positioning accuracy of the hoisting car, so it is widely used in automatic production industries such as home appliances, machinery and electronics, and warehousing and logistics. However, when the weight of the goods in the car is too large, after the goods are transported out of the car, the steel wire rope of the hoist will have a certain elastic deformation, resulting in a deviation in the positioning of the car when it is empty and loaded. The goods are transported from the transport line inside the car to the outsi...
