Tin plate ear rate detection system

Abstract

The invention discloses a detection system for ear rate of tinplate. The system includes a detection module, an optical vision module, a micro-processing module and a PLC control device; the detection module consists of a rotating platform, a sample platform, an X linear module, a Y linear module The rotary platform drives the rotation of the sample platform, and the PLC control device controls the rotation of the rotary platform, the movement of the X linear module, the Y linear module, and the power-on and power-off of the power-off magnetic block; the optical vision module It is composed of a high-precision camera, an optical range finder, a reference rod and a luminous plate, and is set around the sample platform; the micro-processing module controls the action of the high-precision camera, optical range finder and luminous plate, and receives shooting information and distance measurement information. The processing module is connected with the PLC control device through two-way communication. This system adopts optical positioning and optical detection to detect the earing rate of the tinplate, which improves the efficiency and accuracy of the earing rate detection, and accurately reflects the anisotropy performance of the tinplate shaping plane.

Description

technical field [0001] The invention relates to a detection system for ear rate of tinplate. Background technique [0002] With the development and progress of production technology, tinplate is widely used in food and beverage fields, such as beer and beverage cans, food cans, food packaging bottle caps, etc. Due to the high requirements of food quality, higher testing requirements are put forward for the quality inspection of tinplate. The lug rate is one of the important indicators of the quality of the tinplate, and it is an important indicator reflecting the anisotropy performance of the tinplate's plastic plane. [0003] At present, there are two types of tinplate ear rate detectors on the market. The first is to use a displacement sensor to detect the ear-making rate. A small roller with a diameter of about 0.8cm is used to roll on the tinplate sample for one week. With the change of the surface height and height of the tinplate sample, the upper and lower positions...

AI Technical Summary

Problems solved by technology

The ear-making rate detector has the following disadvantages: the small roller cannot detect the concave bottom of the sample, and there is a detection error; the small roller has a pressure on the sample, and the sample is easy to tilt, causing detection errors

This fully automatic ear-making rate detector has the following disadvantages: the effective stroke of the three fixed pins is limited by the diameter of the rotating platform, and the effective stroke cannot meet the requirements of all samples. In this way, the trouble of manually adjusting the three fixing pins is increased, and because the positions of the three fixing pins may be inconsistent when manually adjusting the fixing pins, the sample is not very centered, and even Cause the sample clamp to be crooked, causing detection error
