Description

Technical Field

[0001] This utility model relates to an X-ray non-destructive testing device, specifically a vertical conveyor assembly line device for CT imaging testing. Background Technology

[0002] The application of non-destructive testing (NDT) technology is becoming increasingly widespread, with more and more industries demanding higher precision, particularly in the military and aerospace sectors. These industries require the inspection of a wide variety of workpieces with complex shapes and varying sizes. Existing traditional X-ray digital imaging equipment remains in a manual or semi-automatic inspection state, resulting in low efficiency. Current CT technology performs individual workpiece inspections on a single platform, failing to achieve automated, high-speed, assembly-line inspection. Most existing X-ray assembly line inspection technologies employ a horizontal conveyor structure where inspection flows in from one side of the inspection chamber and out from the other, divided into several inspection areas. This results in a large overall footprint, a bulky system, and significantly higher costs for radiation protection and equipment. Furthermore, the large footprint limits its use in confined spaces, leading to high costs and significant limitations. There is an urgent need for a streamlined inspection system that can perform automated, high-speed inspection while being compact, less restrictive, and widely applicable. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, this utility model provides a vertical conveyor line device for CT imaging inspection, which meets the requirements of automated inspection of workpiece CT imaging, improves inspection efficiency, reduces limitations, and greatly expands the scope of application.

[0005] The reversing conveyor line includes: a reversing conveyor frame, reversing conveyor rollers, a reversing drive motor, a forward conveyor base plate, linear guide rails, a lifting cylinder, a forward conveyor toothed belt guide chain, a forward drive motor, and inlet / outlet guide blocks. The reversing conveyor frame is installed at the rear of the upper assembly line frame and the lower assembly line frame. The reversing conveyor frame is equipped with reversing conveyor rollers and a reversing drive motor, which are connected by a toothed belt. A forward conveyor base plate is located above the reversing conveyor frame. Linear guide rails and a lifting cylinder are directly connected between the reversing conveyor frame and the forward conveyor base plate. The base of the linear guide rail is fixed to the reversing conveyor... On the conveyor frame, the movable end of the linear guide rail is fixed to the lower plane of the forward conveyor base plate. The base of the lifting cylinder is fixed to the reversing conveyor frame, and the movable rod end of the lifting cylinder is fixed to the lower plane of the forward conveyor base plate. The forward conveyor base plate is connected to the forward conveying toothed belt guide chain and the forward drive motor. The forward conveying toothed belt guide chain and the forward drive motor are connected by a chain drive, which drives the toothed belt guide chain to roll and convey. The lifting cylinder moves up and down along the direction of the linear guide rail, which drives the forward conveyor base plate and the forward conveying toothed belt guide chain on it to move up and down. An inlet and outlet guide block is installed above the reversing conveyor frame to guide the workpieces in and out.

[0006] The forward conveying toothed belt guide chain is a long strip guide chain. The forward conveying toothed belt guide chain has a skeleton support in the middle and rollers at both ends for guidance. The guide chain is a standard guide transmission chain structure above the skeleton.

[0007] The drive motor is connected to the upper and lower conveyor rollers by either a toothed belt or a chain.

[0008] The conveyor system is a vertical conveyor structure with two layers. It works in conjunction with the loading and unloading mechanism to transport the workpiece tray and workpieces from the lower conveyor rollers of the lower layer of the conveyor system into the testing chamber. After testing, the workpiece tray and workpieces are lifted and pushed out by the loading and unloading mechanism from the upper conveyor rollers of the upper layer of the conveyor system.

[0009] The beneficial technical effects of this utility model are as follows: By adopting the above technology, the shortcomings and drawbacks of the existing technology are well overcome. It breaks through the barrier of the existing horizontal conveying structure from one side of the detection chamber to the other side. The existing technology has the disadvantages of large overall space, large system, high radiation protection cost and equipment cost, and great limitation of the space to be used. This utility model has the performance of integration. It can not only complete the automatic high-speed detection of the production line, but also has the advantages of small footprint, small limitation, wide applicability, and broad development space.
