Description

Technical Field

[0001] This utility model relates to the field of X-ray inspection technology, and in particular to X-ray inspection systems. Background Technology

[0002] X-ray inspection, one of the five conventional non-destructive testing methods, has a wide range of applications in industry. X-rays are not fundamentally different from natural light; both are electromagnetic waves. However, the energy of X-ray photons is far greater than that of visible light. They can penetrate objects that visible light cannot, and while penetrating the object, they undergo complex physical and chemical interactions with the material. This can cause ionization of atoms, fluorescence in some substances, and photochemical reactions in others.

[0003] The utility model with announcement number CN207528660U discloses a radiation detection system. The radiation source is installed in the middle of the radiation source mounting cylinder and faces upward. The radiation source can swing around the axis of the radiation source mounting cylinder under power drive. The left and right ends of the radiation source mounting cylinder are installed at the bottom of the lead room. The radiation source mounting cylinder can move back and forth under power drive.

[0004] The aforementioned patent document describes a process where at least one lead inlet door and one lead outlet door are closed during the inspection of the workpiece. This saves space and ensures a more comprehensive and complete inspection of the workpiece. However, the overall process is rather cumbersome, and the workpiece is relatively fixed during inspection, which may lead to blind spots in the inspection. Therefore, improvements are needed. Utility Model Content

[0005] The technical problem to be solved by this invention is to overcome the shortcomings of existing technologies that may have blind spots in detection. This invention proposes a radiation detection system.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a radiation detection system, including a base, a sliding groove on the top of the base, a disinfectant tank and a detection chamber fixedly connected to the top of the base, a control panel at the front end of the detection chamber, shielding curtains on both sides of the detection chamber, a radiation generating device inside the detection chamber, a detection conveying mechanism inside the base, and a disinfection mechanism on the top of the base; the detection conveying mechanism includes a motor, a threaded rod, a moving block and a rack, the motor is fixedly installed inside the base, the threaded rod is rotatably connected inside the base, the moving block is slidably connected inside the base, a rotating column is rotatably connected to the top of the moving block, a driven gear is fixedly connected to the surface of the rotating column, a slot is opened on the top of the rotating column, an insert is inserted into the slot, a placement plate is fixedly connected to the top of the insert, the rack is fixedly connected to the top of the base, the output shaft of the motor is fixedly connected to the threaded rod, and the moving block is threadedly connected to the threaded rod through an internal thread.

[0007] Preferably, the rotating column is located inside the slide groove, and the bottom of the placement tray is hollowed out. The slide groove is used to limit the rotation column, and the hollowed-out placement tray allows dust and other debris to fall off.

[0008] Preferably, the teeth on the driven gear are matched with the teeth on the rack, and the number of teeth on the rack is equal to the number of teeth on the driven gear. When the driven gear moves and meshes with the rack, it will rotate, and it will only rotate one full revolution.

[0009] Preferably, the disinfection mechanism includes a pressure chamber, inside which a return spring is installed, and inside the pressure chamber a piston rod is slidably connected via the return spring piston. A suction pipe is passed through and fixedly connected to the rear end of the pressure chamber, and a spray pipe is passed through and fixedly connected to the top of the pressure chamber. An atomizing nozzle is installed at the end of the spray pipe away from the pressure chamber. Both the suction pipe and the spray pipe are equipped with one-way valves. The end of the suction pipe away from the pressure chamber is passed through and fixedly connected to a disinfectant tank.

[0010] Preferably, the one-way valve inside the suction tube is unidirectionally open to the inside of the pressure chamber. When a negative pressure is formed inside the pressure chamber, it will draw disinfectant from the disinfectant tank through the suction tube.

[0011] Preferably, the one-way valve inside the spray pipe is unidirectionally open towards the atomizing nozzle, and the bottom of the atomizing nozzle is higher than the top of the placement plate. When the pressure chamber is squeezed, the cleaning fluid in the pressure chamber will be sprayed out through the spray pipe in conjunction with the atomizing nozzle.

[0012] Compared with the prior art, the beneficial effects of this utility model include: by setting up a detection conveying mechanism, when a workpiece needs to be detected, the workpiece can be placed in the placement tray, and then the motor is turned on to drive the threaded rod to rotate. At this time, through the cooperation of components such as the moving block, rotating column, driven gear, and rack, the placement tray and the workpiece inside it will move into the detection chamber for X-ray detection. During this process, the placement tray will also rotate once so that the workpiece can be detected from all sides.

[0013] By incorporating a disinfection mechanism, when the workpiece is removed from the placement tray after testing and disinfection is required, the motor can be turned on to rotate the threaded rod, causing the placement tray to move to the far right. At this point, the piston rod, pressure chamber, return spring, and other components work together to draw disinfectant from the disinfectant tank through the suction pipe and spray it out through the spray pipe and atomizing nozzle to disinfect the placement tray, preventing it from affecting the testing of the next set of workpieces.

[0021] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0022] According to one embodiment of the present invention, in conjunction with Figures 1-5The X-ray detection system includes: a base 1, a groove 2 on the top of the base 1, a disinfectant tank 3 and a detection chamber 4 fixedly connected to the top of the base 1, a control panel 5 at the front of the detection chamber 4, shielding curtains 6 on both sides of the detection chamber 4, an X-ray generator 7 inside the detection chamber 4, a detection conveying mechanism 8 inside the base 1, and a disinfection mechanism 9 on the top of the base 1; the detection conveying mechanism 8 includes a motor 81, a threaded rod 82, a moving block 83, and a rack 89. The motor 81 is fixedly installed inside the base 1, the threaded rod 82 is rotatably connected inside the base 1, and the moving block 83 is slidably connected inside the base 1. The output shaft of the motor 81 is fixedly connected to the threaded rod 82, and the moving block 83 is threadedly connected to the threaded rod 82 through an internal thread. Turning on the motor 81 can drive the threaded rod 82 to rotate. The rotation of the threaded rod 82 will drive the moving block 83 to move laterally through the engagement of the threads. The top of the moving block 83 is rotatably connected to the rotating column 84. The surface of the rotating column 84 is fixedly connected to the driven gear 85. The top of the rotating column 84 has a slot 86. The slot 86 is inserted into the insert post 87. The top of the insert post 87 is fixedly connected to the placement plate 88. The rotating column 84 is located inside the slide groove 2. The bottom of the placement plate 88 is hollowed out. The slide groove 2 is used to limit the rotation of the rotating column 84. The hollowed-out placement plate 88 allows dust and other debris to fall off. The rack 89 is fixedly connected to the top of the base 1. The teeth on the driven gear 85 are matched with the teeth on the rack 89, and the number of teeth on the rack 89 is equal to the number of teeth on the driven gear 85. When the driven gear 85 moves and meshes with the rack 89, it will rotate and will only rotate one full revolution.

[0023] The disinfection mechanism 9 includes a pressure chamber 91, inside which a return spring 92 is installed. A piston rod 93 is slidably connected to the pressure chamber 91 via the return spring 92. A suction pipe 94 is connected through and fixedly to the rear end of the pressure chamber 91, and a spray pipe 95 is connected through and fixedly to the top of the pressure chamber 91. An atomizing nozzle 96 is installed at the end of the spray pipe 95 furthest from the pressure chamber 91. Both the suction pipe 94 and the spray pipe 95 have one-way valves inside. The one-way valve in the suction pipe 94 is pressure-sensitive. The internal direction of the pressure chamber 91 is unidirectional, and the end of the suction pipe 94 away from the pressure chamber 91 is connected to the disinfectant tank 3 through and fixedly. When a negative pressure is formed in the pressure chamber 91, the disinfectant in the disinfectant tank 3 will be drawn through the suction pipe 94. The one-way valve in the spray pipe 95 is unidirectionally open to the atomizing nozzle 96, and the bottom of the atomizing nozzle 96 is higher than the top of the placement plate 88. When the pressure chamber 91 is squeezed, the cleaning liquid in the pressure chamber 91 will be sprayed out through the spray pipe 95 in conjunction with the atomizing nozzle 96.

[0024] In this embodiment, when the workpiece needs to be inspected, the bottom insert 87 of the placement tray 88 is aligned with the top slot 86 of the rotating column 84 and inserted. The workpiece is placed inside the placement tray 88. The motor 81 is turned on, and the motor 81 drives the threaded rod 82 to rotate through its output shaft. The rotation of the threaded rod 82 causes the moving block 83 to move laterally through the engagement of the threads. The lateral movement of the moving block 83 causes the rotating column 84, the insert 87, the placement tray 88, and the workpiece inside to move into the inspection chamber 4 to cooperate with the X-ray generator 7 for X-ray inspection. When the rotating column 84 moves into the inspection chamber 4, it drives the driven gear 85 to move and mesh with the rack 89. The driven gear 85 rotates, causing the rotating column 84, the insert 87, the placement tray 88, and the workpiece inside to rotate. Only one complete rotation is achieved. This ensures that the workpiece is inspected from all angles, preventing blind spots. After inspection, the workpiece is removed from the other end of the inspection chamber 4. When the workpiece needs to be disinfected, the motor 81 is turned on to rotate the threaded rod 82, causing the placement tray 88 to move to the right and contact the piston rod 93. The piston rod 93 is squeezed and moves to the right, which squeezes the pressure chamber 91, causing the cleaning liquid in the pressure chamber 91 to be sprayed into the placement tray 88 through the spray pipe 95 and the atomizing nozzle 96 for disinfection, preventing it from affecting the inspection of the next set of workpieces. When the placement tray 88 leaves the piston rod 93, the return spring 92 rebounds and moves the piston rod 93 to the left to return to its original position. At this time, a negative pressure is formed in the pressure chamber 91, and the disinfectant liquid in the disinfectant tank 3 is drawn in through the suction pipe 94 to replenish it.

[0025] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
