Description

Background
Before the subsequent processing and production of the fired silicon carbide heat exchange tube, quality indexes such as diameter, straightness, ovality, surface defects and the like of the fired silicon carbide heat exchange tube are required to be detected to see whether the production requirements are met.
The existing straightness measuring method is to slide a measuring tube along the axial direction of a silicon carbide heat exchange tube by using a laser correlation type distance measuring sensor. The prior diameter and ellipticity measuring method, such as Chinese patent CN115112031B, discloses a measuring method and measuring equipment for the outer diameter and straightness of a pipe, which utilize a laser correlation ranging sensor to measure the diameter and ellipticity of the heat exchange pipe by sliding along the axial direction of a silicon carbide heat exchange pipe while rotating the heat exchange pipe. The existing measuring equipment has the following defects:
1. the laser correlation sensor is formed by two correlation and is distributed at an included angle of 90 degrees, when the bending direction of the pipe is consistent with the correlation direction of one group of correlation sensors, the straightness measurement of the pipe is accurate, but when the bending direction of the pipe is inconsistent with the correlation direction of the front correlation sensor, the maximum bending point can not be measured by the scheme, the straightness measurement of the pipe is inaccurate, and the measurement accuracy is lower.
2. The correlation angle of the laser correlation sensor is in a fixed direction, the tube rotates, and because the sensor moves along the axis direction of the tube and measures at the same time, on one hand, two sets of diameter data which may not be on the same section are obtained, so that ellipticity errors are inaccurate; on the other hand, even if two sets of diameter data on the same cross section are obtained, only one set of a large diameter and a small diameter on the same cross section can be measured, and the measured large diameter and small diameter cannot be determined as the maximum diameter and minimum diameter at the cross section, and thus an accurate ovality (ovality is the difference between the values of the maximum diameter and the minimum diameter on a circular cross section) cannot be obtained.
3. The measuring method has slower measuring speed, and the slower the measuring speed is, the more serious the data deviation is, the larger the error is, and the scratch and pit defects on the surface of the pipe cannot be accurately detected.
In addition, the quality detection, the identification printing and the heat exchange tube classification of the prior heat exchange tube adopt the cooperation of manpower and equipment to finish each process, and the heat exchange tube needs multiple circulation and more manpower and larger field; the manual operation error rate is high, the production efficiency is low, the cost is high, and the large-scale production is not easy.

Fourth, after the heat exchange tube marking is completed, the movable tube rack group at one end of the tube coming direction of the sorting mechanism transfers the heat exchange tubes on the fixed tube rack group at the marking mechanism to the fixed tube rack group at the sorting mechanism, and according to the diameter data information of the heat exchange tubes, the transition bracket of the sorting mechanism guides and conveys the heat exchange tubes to the storage spaces with corresponding diameters of the multi-layer storage bins to complete sorting actions. So far, the loading, scanning, marking, sorting and warehousing of one heat exchange tube are finished.
And simultaneously repeating the third step, moving the heat exchange tube after the next scanning detection to the marking mechanism, and printing the mark according to the third step.
The whole process does not need to be manually participated, and only the heat exchange tube is manually placed on the feeding frame.
The foregoing is illustrative of the best mode of carrying out the invention, and is not presented in any detail as is known to those of ordinary skill in the art. The protection scope of the invention is defined by the claims, and any equivalent transformation based on the technical teaching of the invention is also within the protection scope of the invention.
