Automobile rain inspection conveying electric control system and method

Abstract

The invention relates to an automobile rain inspection conveying electric control system and method. A drive shaft and a tension shaft are rotatably mounted on a conveying frame. A drive wheel is fixed on the drive shaft. A tension wheel is fixed on the tension shaft. A roller shaft is rotatably mounted on the conveying frame between the drive shaft and the tension shaft. A roller is fixed on the roller shaft. A plate strip is arranged on the drive wheel and the tension wheel. A main drive motor and a standby drive motor are arranged on the conveying frame on one side of the drive shaft. The drive shaft is driven by the main drive motor. A main tension motor and a standby tension motor are arranged on the conveying frame on one side of the tension shaft. The tension shaft is driven the main tension motor. The main drive motor and the main tension motor rotate in the same direction. According to the automobile rain inspection conveying electric control system and method, dual-motor servo control is adopted, the traditional tension component is not required, creeping easily caused by the use of a common plate strip is avoided, and tension and system damping can be adjusted online.

Description

technical field [0001] The invention relates to an electric control system and an electric control method applied to a conveying system for testing the sealing of a closed part of a whole vehicle. Background technique [0002] The electric control system of the traditional steel belt and belt conveyor adopts single-side drive, and is equipped with a mechanical tension drive scheme, which has the disadvantages of easy crawling. Later, dual-motor control was adopted to better realize the automatic adjustment of the tension of the strip, but now the dual-motor control is commonly used in plastic strip conveying systems, and the tensioning motor and the driving motor output reverse torque among the two motors. This control method not only makes the tensioning motor do work, but also needs to increase the braking resistor to absorb energy, and the reverse torque is not easy to adjust, the speed is difficult to control, and it is easy to cause failures such as the strip pin breaki...

Problems solved by technology

[0002] The electric control system of the traditional steel belt and belt conveyor adopts single-side drive, and at the same time configures the drive scheme of mechanical tension, which has the disadvantages of easy crawling and so on.

Later, dual-motor control was adopted to better realize the automatic adjustment of the tension of the strip, but now the dual-motor control is commonly used in plastic strip conveying systems, and the tensioning motor and the driving motor output reverse torque among the two motors. This control method not only makes the tensioning motor do work, but also needs to increase the braking resistor to absorb energy, and the reverse torque is difficult to adjust, the speed is difficult to control, and it is easy to cause failures such as strip pin breaking or tensioning motor damage.
