Description

Technical Field

[0001] The invention relates to the technical field related to sealing test of a sealed seed source titanium alloy tube, and in particular to a sealing test device and method for a sealed seed source titanium alloy tube. Background Art

[0002] The sealed seed source structure mainly consists of a titanium alloy tube with an outer shell structure, a silver wire as the core material, and the surface of the silver wire is plated with iodine [I-125] isotope. The two ends of the titanium alloy tube are formed by laser welding. If the welding point is damaged, or the surface of the titanium alloy tube is damaged and cracks exist, the iodine [I-125] isotope in the titanium alloy tube will be released into the environment or enter the human body fluids, causing harm to the human body. Therefore, it is necessary to use a test device to test the sealing of the titanium alloy tube to ensure that the sealed seed source is safe enough in actual use.

[0003] A titanium alloy tube sealing test system with application number 202310290821.2 for sealing seed sources comprises a test box, several of which are connected and distributed in sequence, an opening and closing door is rotatably installed on the upper end of the test box, a supporting unit for supporting the titanium alloy tube and an attaching unit for attaching filter paper are sequentially arranged in the test box from top to bottom, and test units for attaching ends and driving the titanium alloy tube to rotate are arranged in the test box and on both sides of the supporting unit; the present invention cooperates with the test unit and the attaching unit to tightly attach the filter paper and the filter paper cover to the surface of the titanium alloy tube to ensure that the filter paper and the filter paper cover can extract the sealing seed source leaking from the surface of the titanium alloy tube, so as to facilitate the subsequent testing of the sealing seed source activity by an activity tester to determine whether the titanium alloy tube has a leakage problem.

[0004] However, the above-mentioned testing system still has certain problems in actual use. For example, when testing titanium alloy tubes, the titanium alloy tubes need to be manually placed in the test box. After the test is completed, the tested titanium alloy tubes need to be removed and the titanium alloy tubes to be tested need to be placed again. This will result in a large workload for the staff when multiple titanium alloy tubes need to be tested, thereby reducing the test efficiency. Summary of the invention

DETAILED DESCRIPTION

[0053] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0054] Example: Figure 1-Figure 6As shown, the present invention provides a sealing test device and method for a titanium alloy tube of a sealed seed source, comprising: a test box 10 and at least eight titanium alloy tubes 11; an automatic feeding assembly 20 is arranged at the top of the test box 10, and the automatic feeding assembly 20 is used to stack and feed the titanium alloy tubes 11 one by one; a blanking channel 12, the blanking channel 12 is located on one side of the automatic feeding assembly 20 and the bottom passes through the test box 10 and is placed inside the test box 10, and a position-adjustable limiter is arranged on the outside of the blanking channel 12 located inside the test box 10 The blocking mechanism 30 is used to limit the titanium alloy tube 11 that falls into the blanking channel 12; the sealing detection component 40 is used to detect the sealing effect of the outer wall of the titanium alloy tube 11. It is located at the bottom of the blanking channel 12 and one end passes through the test box 10 and is placed outside the test box 10; the automatic material collecting component 50 is used to collect and store the titanium alloy tube 11 after detection. It is located on one side of the sealing detection component 40 and one end passes through the other side of the test box 10 and is placed outside the test box 10.

[0055] Among them, Figure 1 and Figure 2 As shown, the automatic loading component 20 includes an arc-shaped placement frame 21 with a quarter arc cross-section and a top opening vertically upward, and the titanium alloy tubes 11 are limited and stacked in the arc-shaped placement frame 21; the bottom opening of the arc-shaped placement frame 21 is horizontally arranged and a feeding cylinder 22 is arranged on one side of the opening, and a feeding inlet 23 for the titanium alloy tube 11 to enter is opened on one side of the feeding cylinder 22, and a servo motor 24 for driving the feeding cylinder 22 is arranged on one side.

[0056] It should be noted that: through the setting of the arc-shaped placement frame 21, multiple titanium alloy tubes 11 to be tested can be stacked and placed, and when the servo motor 24 rotates, it will drive the feeding cylinder 22 to rotate. When the feeding cylinder 22 rotates to make the feed inlet 23 correspond to the bottom opening of the arc-shaped placement frame 21, the bottom titanium alloy tube 11 will be pressed into the feeding cylinder 22 by the pressure of the top titanium alloy tube 11;

[0057] Furthermore, when the feeding cylinder 22 continues to rotate, the bottom opening of the arc-shaped placement frame 21 will be blocked by its outer wall. At this time, the titanium alloy tube 11 at the bottom will be blocked. When the feeding cylinder 22 rotates to the point where the feed inlet 23 corresponds to the blanking channel 12, the titanium alloy tube 11 in the feeding cylinder 22 will fall along the blanking channel 12 to the inside of the test box 10 for inspection. When the inspection is completed, the servo motor 24 will continue to work and drive the feeding cylinder 22 to load the material, thereby realizing automatic loading of the titanium alloy tubes 11 to be inspected one by one.

[0058] Among them, Figure 2As shown, both ends of the blanking channel 12 are open, and an inverted U-shaped limit stopper 13 is fixedly provided on the side of the top of the blanking channel 12 away from the feeding cylinder 22.

[0059] In detail, the setting of the limit stopper 13 can block the titanium alloy tube 11 falling from the feeding cylinder 22 into the blanking channel 12, thereby preventing the titanium alloy tube 11 from falling.

[0060] Among them, Figure 4 and Figure 5 As shown, the limit blocking mechanism 30 includes two sliding limit plates 31, and the two sliding limit plates 31 are respectively slidably arranged in sliding grooves opened on both sides of the blanking channel 12, and sliding rods 32 are fixedly arranged on both sides of the top of the two sliding limit plates 31, and the top of the sliding rod 32 is slidably connected to the blanking channel 12.

[0061] Specifically, through the cooperation of the sliding rod 32 , the sliding limit plate 31 can slide in the sliding groove, and the position stability of the sliding limit plate 31 when sliding in the sliding groove can also be improved.

[0062] Among them, Figure 4 As shown, two rack plates 33 arranged in the vertical direction are fixedly provided on the outer side of one of the sliding limit plates 31, and a rotating gear 34 is meshed with one side of the rack plate 33, and the axis of the two rotating gears 34 is connected to the same connecting shaft 35; a worm 36 is fixedly provided in the middle of the connecting shaft 35, and a worm wheel 37 is matched with the top of the worm 36, and a servo motor 38 for driving the worm wheel 37 is provided in the test box 10; both ends of the two sliding limit plates 31 are fixedly connected by a connecting member, and the connecting member is a U-shaped fixed rod 39 with both ends bent inward at right angles, and the bent ends of the fixed rod 39 are respectively fixedly connected to the two sliding limit plates 31.

[0063] It should be noted that the servo motor 38 drives the worm wheel 37 to rotate, and the rotation of the worm wheel 37 drives the worm 36 to rotate, and the rotation of the worm 36 can drive the connecting shaft 35 to rotate, and the rotation of the connecting shaft 35 drives the two rotating gears 34 to rotate at the same time, and the rotation of the rotating gear 34 drives the rack plate 33 to move upward or upward, and the rack plate 33 moves to drive the sliding limit plate 31 to move. When the sliding limit plate 31 moves to the highest position, the limit on the titanium alloy tube 11 can be removed;

[0064] Furthermore, by setting the fixing rod 39, the two sliding limit plates 31 can be connected, so that when one of the sliding limit plates 31 moves, the other sliding limit plate 31 can be driven to move at the same time.

[0065] Among them, Figure 6-Figure 9 As shown, the sealing detection component 40 includes a driving part for rotating the titanium alloy tube 11 and a part for extracting the sealing seed source leaked from the outer wall of the titanium alloy tube 11; the driving part includes a cylinder 41 and a driving motor 42, the cylinder 41 and the driving motor 42 are arranged opposite to each other and fixedly arranged on both sides of the test box 10, and the output end of the cylinder 41 is rotatably provided with a tightening plate 43, and the output end of the driving motor 42 is fixedly provided with a tightening plate 44, and the tightening plate 43 and the tightening plate 44 are respectively located on both sides of the titanium alloy tube 11 to be detected; the extraction part includes a conveying belt 45, and the conveying belt 45 is inclined downward at one end close to the blanking channel 12, and a driving motor 46 for driving the conveying belt 45 is arranged on one side outside the test box 10; a plurality of pasting grooves 47 are equidistantly provided on the outer surface of the conveying belt 45, and extraction test papers 48 are pasted in the pasting grooves 47.

[0066] In detail, when the titanium alloy tube 11 to be tested falls along the blanking channel 12 onto the conveyor belt 45 and contacts the extraction test paper 48 thereon, the cylinder 41 then drives the clamping plate 1 43 to move and push the titanium alloy tube 11 and clamp it against the clamping plate 2 44. The titanium alloy tube 11 is tightly connected by the clamping plate 1 43 and the clamping plate 2 44. When the driving motor 1 42 drives the clamping plate 2 44 to rotate, the titanium alloy tube 11 will rotate together. In this way, the outer wall of the titanium alloy tube 11 can completely contact the extraction test paper 48. If the sealing seed source leaks, the existence of the sealing seed source can be detected when the extraction test paper 48 is subsequently tested.

[0067] Furthermore, when the titanium alloy tube 11 is inspected and collected by the automatic collecting assembly 50, the driving motor 2 46 will drive the conveyor belt 45 to move, thereby driving the next unused extraction test paper 48 to the bottom of the blanking channel 12 for use in the next titanium alloy tube 11 inspection. In actual use, corresponding marks can be made between each extraction test paper 48 and the titanium alloy tube 11. When the tested extraction test paper 48 is transported to the outside of the test box 10, the staff can tear it off from the pasting groove 47 to detect whether there is a sealing seed source on it. If so, the corresponding titanium alloy tube 11 on the surface is leaking, otherwise there is no leakage.

[0068] Among them, Figure 1 , Figure 10-12 As shown, the automatic material receiving assembly 50 includes a material receiving box 51, which is located on one side of the conveyor belt 45 and has a top opening lower than the conveyor belt 45. A baffle 14 is provided at the bottom of the inner cavity of the test box 10 to block the material receiving box 51, and an electromagnet 15 is provided on the baffle 14 to adsorb and fix the position of the material receiving box 51.

[0069] It should be noted that, by setting the baffle 14, the position of the material receiving box 51 in the test box 10 can be limited to prevent the material receiving box 51 from directly contacting the conveyor belt 45 and affecting the rotation of the conveyor belt 45, and by setting the electromagnet 15, it can attract the metal part set at the corresponding position of the material receiving box 51, thereby improving the stability of the position of the material receiving box 51 in the test box 10.

[0070] Among them, Fig.11 and Fig.12 As shown, a carrying plate 52 is slidably provided inside the material receiving box 51, and sliding blocks are fixedly provided at both ends of the carrying plate 52, and the sliding blocks are slidably provided in the sliding grooves opened on the inner wall of the material receiving box 51; a traction rope 53 is provided at the top of the two sliding blocks, and one end of the traction rope 53 passes through the through hole 56 and bypasses the guide wheel 54 to be wound around the winding reel 55; the guide wheel 54 is fixedly provided on the top edge of the material receiving box 51, and a winding motor 57 for driving the winding reel 55 is provided on the material receiving box 51.

[0071] In detail, the winding motor 57 drives the winding spool 55 to rotate, and the traction rope 53 is wound by the winding spool 55. At this time, the traction rope 53 pulls the carrying plate 52 to slide upward. When the winding motor 57 rotates in the opposite direction, the traction rope 53 is released. At this time, the carrying plate 52 moves downward under the action of gravity, and then the position of the carrying plate 52 in the receiving box 51 can be adjusted by the winding motor 57 to retract or release the traction rope 53.

[0072] Furthermore, when there are no tested titanium alloy tubes 11 stored in the material receiving box 51, the supporting plate 52 can be moved to the top of the inner cavity of the material receiving box 51, so that when the tested titanium alloy tubes 11 roll from the conveyor belt 45 into the material receiving box 51, there will be no violent collision with the material receiving box 51, which can protect the titanium alloy tubes 11. As the number of titanium alloy tubes 11 in the material receiving box 51 increases, the position of the supporting plate 52 is gradually adjusted downward.

[0073] The present invention also provides a method for testing the sealing of a titanium alloy tube of a sealed seed source, comprising the following steps:

[0074] S1: stacking a plurality of titanium alloy tubes 11 to be tested in an arc-shaped placement frame 21, and pasting the same number of extraction test papers 48 in the pasting groove 47;

[0075] S2: The servo motor 24 drives the feeding cylinder 22 to rotate and feed the titanium alloy tube 11. The titanium alloy tube 11 falls along the material dropping channel 12 onto the conveying belt 45 and contacts the extraction test paper 48.

[0076] S3: The cylinder 41 pushes the clamping plate 1 43 to move, and the titanium alloy tube 11 to be tested is clamped by the clamping plate 1 43 and the clamping plate 2 44, and then the driving motor 1 42 drives the titanium alloy tube 11 to rotate, so that the outer wall of the titanium alloy tube 11 can be in contact with the extraction test paper 48 for detection;

[0077] S4: After the detection is completed, the servo motor 2 38 works to drive the two sliding limit plates 31 to move upward to remove the limit on the titanium alloy tube 11, and the cylinder 41 drives the clamping plate 1 43 to retract. At this time, the titanium alloy tube 11 after the detection will directly roll and fall into the material receiving box 51 for collection.

[0078] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
