Description

Technical Field

[0001] The utility model belongs to the technical field of industrial DR detection, and in particular relates to an industrial DR detection device based on flat belt transmission. Background Art

[0002] Industrial DR testing, as a nondestructive method for examining a product's internal structure, is widely used across various industries. Industrial DR testing uses X-rays to penetrate the product being inspected and illuminate a detector for real-time imaging. The detector displays images with varying grayscale values based on the density of each part of the product, allowing for the detection of internal structural defects. In conventional industrial DR testing, the product to be inspected is typically transported to the DR inspection station by a conveyor or manually. It is then moved between an X-ray emitter and receiver (i.e., the detector) by a robot, fixture, or manually for inspection. The inspected product is then removed from the X-ray emitter and receiver. This results in low inspection efficiency on the production line. Furthermore, existing industrial DR testing equipment only uses line scan detectors for flat belt surface inspection, which does not meet high inspection standards. Utility Model Content

[0003] The purpose of the utility model is to provide an industrial DR detection device based on flat belt drive to solve the technical defects described in the background technology.

[0005] According to the technical solution, when the conveyor belt device of the industrial DR inspection equipment transports the product to a certain target location, the product will pass between the flat-panel receiving device and the X-ray tube. At this time, the X-ray rays emitted by the X-ray tube will penetrate the passing product and irradiate the flat-panel receiving device, thereby inspecting the internal structure of the product. Therefore, the utility model achieves the following beneficial effects:

[0006] The present invention can complete DR inspection while the conveyor belt device is transporting the product to a certain target location, without the need to deliberately move the product from the conveyor line to between the flat-panel receiving device and the X-Ray tube. After the product has completed DR inspection, there is no need to use a robot, a clamp or manual labor to take the product out from between the flat-panel receiving device and the X-Ray tube. Therefore, the inspection efficiency of the product on the product production line is greatly improved. At the same time, the present invention cooperates with the X-Ray tube and the flat-panel receiving device to increase the imaging area and clarity and ensure the correct image ratio, thereby improving the inspection effect and meeting higher standards and requirements.

[0034] The flat plate receiving device 4 includes a receiver mounting frame 41 and a flat plate receiver 42. The receiver mounting frame 41 is fixedly installed in the frame cover 1. The receiver mounting frame 41 is installed with a receiver screw module 43 that drives the flat plate receiver 42 to rise and fall. The flat plate receiver 42 is located above the conveyor belt device 3.

[0035] The base plate 2 is equipped with a slide rail 21 , a frame drive module, an adjustment frame 61 and a ray tube lead screw module 51 .

[0036] The two ends of the conveyor belt device 3 pass through the frame outer cover 1 and are used to connect to another conveying device or production line equipment. The conveyor belt device 3 includes a conveyor belt 31 and two conveyor frames 32 arranged on the left and right. The two conveyor frames 32 are both provided with a belt support shaft 33. One of the conveyor frames 32 is equipped with a conveying motor 34 that drives the belt support shaft 33 to rotate. The conveyor belt 31 surrounds the belt support shafts 33 on the two conveyor frames 32. When transporting products, the products are placed on the conveyor belt 31. The conveyor belt 31 is parallel to the flat plate receiver 42. Each conveyor frame 32 is equipped with a slider 35, and the slide rail 21 cooperates with the slider 35. The frame drive module is used to drive the two conveyor frames 32 to move closer or open to each other. The frame drive module can be a screw module, a belt module or a cylinder module, etc., which can drive the two conveyor frames. 32 modules that are close to or open to each other; a number of empty holes 36 are arranged on the conveyor belt 31, and a product sensor 37 for identifying whether there is a product on the conveyor belt 31 through the empty holes 36 is installed on the conveyor frame 32 located in front of the flat plate receiving device 4. The product sensor 37 can be an infrared distance sensor or a visual system that can identify whether there is a component on the conveyor belt 31; a guide beam 38 is installed on the conveyor frame 32 located in front of the flat plate receiving device 4, which is horizontally extended above the conveyor belt 31. The guide beam 38 is provided with a positioning plate 39 located above both sides of the conveyor belt 31 for pushing the product to the center of the conveyor belt 31. The positioning plate 39 can slide on the guide beam 38 and can be fixed at a certain position. The positioning plate 39 can be fixed to a certain position on the guide beam 38 by screws or buckles.

[0037] The axis of the adjustment frame 61 is connected to a rotatable adjustment shaft 62, which can be fixed to the adjustment frame 61 at a certain rotation angle by means of screws, clamping rings or buckles.

In addition, when another product sensor can identify that the product is between the flat panel receiving device 4 and the X-Ray tube 52, the conveyor belt device 3 can suspend the transportation of the product, so that the product temporarily remains between the flat panel receiving device 4 and the X-Ray tube 52; thereafter, the X-RAY rays emitted by the X-Ray tube 52 will penetrate the passing product and irradiate the flat panel receiving device 4, so that the flat panel receiving device 4 displays images with different grayscale values, thereby realizing DR detection of the internal structure of the product; after the product is inspected, the conveyor belt device 3 continues to transport the product to a certain target position, and the product is moved out from between the flat panel receiving device 4 and the X-Ray tube 52.

[0041] When the conveyor belt 31 on the conveyor belt device 3 needs to be replaced or repaired, the frame drive module drives the two conveyor frames 32 to move closer together to stop tightening the conveyor belt 31. At this time, the conveyor belt 31 can be removed from the conveyor frames 32 for replacement or repair. Thereafter, the repaired or new conveyor belt 31 is wrapped around the belt support shafts 33 on the two conveyor frames 32. The frame drive module then drives the two conveyor frames 32 to open toward each other to tighten the conveyor belt 31. When the conveyor belt device 3 is transporting products to the target location, the conveying motor 34 drives the belt support shaft 33 to rotate, which in turn drives the conveyor belt 31 to move, thereby transporting the products placed on the conveyor belt 31 to the target location.
