Description
Technical Field
The utility model relates to a frock field especially relates to a frock for article detecting system.
Background
Referring to a tool for an article inspection system, which is applied by the applicant on 29/05/2015, the granted publication number of the patent is CN204649989U, the tool is used for collecting X-ray images of articles, a driving mechanism drives an object to be inspected to rotate around an X-axis, and a first positioning plate drives a second positioning plate to rotate together through a positioning rope. And when the first positioning plate rotates, the synchronous belt wheel on the worm gear mechanism rotates around the synchronous belt wheel fixed on the rack through the synchronous belt, so that the worm gear mechanism rotates to drive the first positioning plate to turn around the Z axis. The first positioning plate and the second positioning plate are connected through a positioning rope, so that the second positioning plate is driven to turn over, and the two positioning plates are kept in parallel. And the object to be detected is fixed on the positioning rope between the two positioning plates, so the object to be detected rotates around the Z axis while rotating around the X axis, the object to be detected can be stopped at any angle, and at the moment, the article detection system and the object to be detected together pass through the X-ray machine by using tooling, so that an X-ray scanning picture of the object to be detected at the angle is obtained.
However, the patent currently has the following problems:
1. the positioning rope and the positioning plate are rigidly connected, and the two positioning plates cannot be absolutely parallel in the processes of processing, assembling and debugging. Therefore, after the tool runs for a long time, the positioning rope is loosened due to the influence of alternating tension. The positioning plate is deformed seriously, so that the image acquisition is difficult;
2. the driving mechanism directly drives the first mounting mechanism to rotate, and then drives the second mounting mechanism to rotate through the positioning rope. Because the positioning rope is flexible, the first mounting mechanism and the second mounting mechanism are driven by the positioning rope to not synchronously rotate, and the first mounting mechanism does not necessarily rotate at a constant speed because the bearing has certain friction force, assembly precision and other problems. Resulting in the object to be detected not being positioned in the desired position. The positioning rope bears certain torsion while bearing tensile force, so that the loosening phenomenon of the positioning rope is aggravated;
3. the driving mechanism drives the first mounting mechanism to rotate, and the belt wheel drives the worm and gear mechanism to rotate, so that the positioning plate is turned over. The positioning plate is turned to the limit position, the driving mechanism is manually stopped, and then the driving mechanism is switched to rotate reversely, so that the positioning plate rotates reversely. When the locating plate rotates to the limit position, in order to realize reverse overturning of the locating plate, the reverse rotation of the driving mechanism needs to be manually switched, and automatic control cannot be realized. And the operator is required to visually observe the limit position, the positioning is not accurate, and the operation is more complicated.
