Abstract

The present invention discloses a quality measurement device and method. The device comprises a conveyor belt, a laser range finding module, a speed measurement module and an embedded analysis module. The speed measurement module is configured to measure the travel speed of the conveyor belt; the laser range finding module comprises a plurality of laser range finding sensors being in linear arrangement at intervals, the laser range finding sensors perform range finding along the direction perpendicular to a conveying surface, and are distributed along the direction being perpendicular to the travel speed of the conveyor belt; and the laser range finding module is connected with the embedded analysis module through a collection card, and the speed measurement module is connected with the embedded analysis module. The quality measurement device and method are fast in measurement reaction speed, cannot not cause measurement error because of cheap material stack positions and more accord with the usage requirement in the actual production.

Description

technical field [0001] The invention relates to a quality measuring device and a measuring method, in particular to a quality measuring device and a measuring method suitable for conveyor belts. Background technique [0002] At present, among industrial material measuring devices, static measuring buckets and mechanical belt scales are mostly used. [0003] The weighing hopper statically measures the quality of the material in the hopper through the weight sensor. This measurement method does not have a dynamic measurement function, which increases the workload and affects the industrial production efficiency. The harsh working environment will also greatly affect the accuracy of detection. [0004] The mechanical belt scale is an online measurement system composed of pressure sensors, speed sensors, etc. This kind of measuring device is a direct contact measuring method. When the material passes through the belt scale, the unevenness of the position and the speed will aff...
