Description

Technical Field

[0001] The present invention relates to the technical field of insulating cardboard detection, and particularly to an X-ray detection device for insulating cardboard. Background Art

[0002] The published patent with the publication number CN210512930U discloses an insulating cardboard detection system. The insulating cardboard thickness measurement device behind the first belt conveyor includes a frame, an upper bracket and a lower bracket are both fixed on the frame. There is an upper air cylinder on the upper bracket, an upper contact roller is installed at the lower end of the piston rod of the upper air cylinder, there is a pressing plate at the bottom of the upper contact roller, and a thickness gauge is installed on the upper air cylinder; there is a lower air cylinder on the lower bracket, and a lower contact roller is installed at the upper end of the piston rod of the lower air cylinder. The insulating cardboard metal detection device in front of the first belt conveyor includes a frame, an upper X-ray detector and a lower X-ray detector are arranged above and below the opening in the middle of the frame; the insulating cardboard surface quality detection device in front of the second belt conveyor includes a frame, and cameras are arranged above and below the opening in the middle of the frame. This patent is designed to solve the problems that the current manual detection of the thickness, surface defects, etc. of insulating cardboard is slow, time-consuming and laborious.

[0003] The varieties of insulating cardboard mainly include low-density boards, medium-density boards and high-density boards classified by density. When performing X-ray detection on high-density insulating cardboard, it is necessary to ensure accurate setting of equipment parameters, stable placement and accurate position of the test piece in order to obtain clear X-ray images. By interpreting and analyzing the images, it can be determined whether there are defects inside the insulating cardboard, such as cracks, surface or internal metal foreign objects, etc. X-ray detection is a non-destructive testing technology and can be used for the quality detection of materials such as insulating cardboard without damaging the test piece.

[0004] By adjusting the detection range of the X-ray machine, the operator needs to select appropriate detection areas and parameters according to the size, shape, material of the insulating cardboard and the specific requirements of the detection. By adjusting the detection range, it is ensured that the X-ray can penetrate the insulating cardboard to achieve a comprehensive detection of the entire insulating cardboard, while avoiding radiation to unnecessary areas, so as to better judge the quality of the insulating cardboard. However, the existing insulating cardboard is not fixed in position on the conveyor belt and shifts, which is likely to cause misjudgment by the X-ray machine. At the same time, the X-ray machine can detect the thickness of the insulating cardboard but cannot detect the length and width of the insulating cardboard. When the insulating cardboard has requirements for dimensions, it is still necessary for manual workers to measure the dimensions of the insulating cardboard using a tape measure or a vernier caliper, etc., which is time-consuming and laborious.
