System and method for accurately measuring length in compensation chain boxing process

Abstract

The invention discloses a system and a method for accurately measuring the length in a compensation chain boxing process. The system comprises main control equipment, and a length measuring device, a transmission device, a clamping device and a compensation chain which are arranged on a supporting table. The length measuring device comprises an industrial camera installed at a chain outlet of the supporting table, a code spraying device installed at the left end of the supporting table and a hollow shaft encoder arranged at the right end of the supporting table. The transmission device comprises a first servo motor located at the right end of the supporting table and a conveying belt arranged above a cross beam of the supporting table in parallel. The clamping device comprises a chain inlet device and a chain outlet device which are the same in structure and arranged at the left end and the right end of the supporting table respectively. When the system works, the main control equipment firstly controls the clamping device to apply a certain pressure to the compensation chain and controls the length measuring device and the transmission device to work cooperatively, and finally, the main control equipment multiplies the pulse number of the hollow shaft encoder by a compensation coefficient k to achieve the purpose of high-precision length measurement.

Description

technical field [0001] The invention relates to the technical field of an intelligent length precise measurement, detection and alarm system, in particular to an accurate length measurement system and a method thereof during the packing process of a compensation chain. Background technique [0002] Accurate measurement and monitoring of the length of the compensation chain is particularly important during the packing process of the compensation chain. Since each packing has a uniform specification for the length of the compensation chain, the measurement requirements are particularly strict, and the control length cannot be accurately controlled by manual labor. Measurements are also time-consuming and labor-intensive. With the development of science and technology and the improvement of various hardware levels, processing algorithms such as preprocessing, segmentation, feature extraction and selection, and defect classification and recognition of various signal images are b...

Problems solved by technology

However, the compensation chain drive is driven by the motor. If the rotating shaft of the motor is set as a rotating disk, the final error will be large because the diameter of the shaft is too small; The precision drops, and there is no feedback alarm function. If there is an error in the middle, it will not be known at all. Only an overall error will be obtained in the final calculation, and rework and adjustment will be time-consuming and laborious. In addition, the surface of the cable is completely different from the compensation chain. Because the surface material of the cable is smooth, Therefore, the counting error is small by multiplying the number of rotations by the circumference of the rotating disk, but it is counterproductive to apply to the compensation chain with uneven surface, resulting in an increase in the measurement error. Therefore, this device and method are not applicable to the installation of the compensation chain around the chain through analysis. box system
