Description

Technical Field

[0001] This utility model belongs to the field of radioactive source processing, and in particular relates to a feeding device for a radioactive source density source. Background Technology

[0002] Radioactive source density generators are core components of fluid density detection equipment in industries such as petroleum, chemical, and food processing. They must be precisely assembled onto the radioactive source core to ensure the accuracy of density detection data. In traditional production processes, the loading of density generators largely relies on manual operation. Firstly, due to the radiation characteristics of radioactive sources, direct human contact poses occupational health and safety risks. Secondly, the limited accuracy of manual positioning can easily lead to assembly deviations between the density generator and the source core, thus affecting subsequent detection accuracy. Furthermore, manual loading is inefficient and difficult to match the continuous operation rhythm of automated production lines, thus limiting overall capacity improvement. Utility Model Content

[0032] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] like Figure 1As shown, a feeding device for a density source of a radioactive source includes a feeding unit 1 and a tightening unit 2. The feeding unit 1 is set on the processing production line of the radioactive source core, and the tightening unit 2 is set on one side of the feeding unit 1. The tightening unit 2 is fixedly installed on the production line. The feeding unit 1 is used to transport the density source, and the tightening unit 2 is used to install the density source on the source core.

[0034] The material distribution unit 1 includes a support 11, a material distribution component 12, and a material preparation component 13. The support 11 is fixedly installed on the radioactive source core processing production line. The material distribution component 12 is set on the upper end of the support 11. One end of the material distribution component 12 is fixedly connected to the material preparation component 13. The material preparation component 13 is located on one side of the tightening unit 2. The material distribution unit 1 can work closely with other workstations on the radioactive source processing production line to accurately transfer the density source to the correct position. It is compatible with the automated process of the entire radioactive source assembly, which greatly improves the assembly efficiency. Moreover, this process does not require manual intervention, reducing the risk of manual contact with radioactive source-related components.

[0035] like Figure 2 As shown, the material distribution assembly 12 includes a first cylinder 121, a slide block 122, and a material distribution plate 123. Two slide blocks 122 are fixedly installed on the upper end of the bracket 11. The two slide blocks 122 are arranged parallel to each other, and each slide block 122 is slidably connected to the periphery of the material distribution plate 123. One end of the material distribution plate 123 is fixedly connected to the movable end of the first cylinder 121, and the other end of the material distribution plate 123 is fixedly connected to the material preparation assembly 13. The first cylinder 121 is fixedly installed on the upper end of the bracket 11. The first cylinder 121 is prior art, and its model is MD25x20-S20. Figures 3-5 As shown, the material preparation assembly 13 includes a first support plate 131, a second support plate 136, a pushing part, and a receiving part. The first support plate 131 is fixedly installed on the upper end of the bracket 11. A pushing part is provided at one end of the first support plate 131, and a receiving part is provided at one end of the second support plate 136. A material distribution plate 123 is fixedly connected to the outer side of the second support plate 136. The first cylinder 121 drives the second support plate 136 to move closer to or away from the first support plate 131 through the material distribution plate 123. The first support plate 131 is provided with a feeding groove, and the second support plate 136 is provided with an arc-shaped groove. The feeding groove can communicate with the arc-shaped groove. Multiple density sources 3 are placed in the feeding groove in sequence. The pushing part is used to send the density sources 3 into the receiving part in sequence along the direction of the feeding groove.

[0036] like Figures 3-6As shown, the pushing part includes a second cylinder 132 and a pushing block 133. The second cylinder 132 is fixedly mounted on one end of the first support plate 131. The movable end of the second cylinder 132 is fixedly connected to the pushing block 133, and the periphery of the pushing block 133 is slidably connected to the feeding groove. The receiving part includes a third cylinder 134 and a clamp 135. The third cylinder 134 is mounted on one end of the second support plate 136. The movable end of the third cylinder 134 is fixedly connected to one end of the clamp 135. The other end of the clamp 135 has a clamping groove for clamping the density source. The clamp 135 is a plastic elastic clamp. The second cylinder 132 is prior art, and its model number is MD25x20-S20. The third cylinder 134 is prior art, and its model number is MD25x20-S20.

[0037] Multiple density sources 3 are sequentially placed in the feeding groove of the first support plate 131, and the feeding groove is connected to the arc-shaped groove of the second support plate 136. The third cylinder 134 of the receiving unit drives the clamp 135 to move to the receiving position close to the arc-shaped groove, and the clamp 135 is slidably connected to the square hole of the second support plate 136. The movable end of the second cylinder 132 drives the pusher block 133 to slide along the feeding groove, pushing the density sources 3 in the feeding groove into the arc-shaped groove in sequence, and then into the clamping end of the clamp 135. Then the third cylinder 134 extends. The clamp 135 is pushed to slide within the square hole, utilizing the plastic elasticity of the clamp 135 to clamp the density source 3. Since the outer side of the second support plate 136 is fixedly connected to the distribution plate 123, when the first cylinder 121 drives the distribution plate 123 to slide along the slide block 122, it will drive the second support plate 136 to move as a whole to one side of the tightening unit 2, completing the preparation for conveying the density source 3. When the tightening head of the tightening unit 2 moves down and locks the density source 3, the movable end of the second cylinder 132 retracts, squeezing the density source 3 out of the clamp 135. The second support plate 136 is reset under the action of the distribution plate 123, and the pusher block 133 also returns to its position under the action of the second cylinder 132, waiting for the next feeding cycle. The distribution unit 1 is set up so that the density source can be accurately transferred to the handover position that matches the tightening unit 2, which is compatible with the entire automated process of radioactive source processing, greatly improving assembly efficiency. Moreover, this process does not require manual intervention, reducing the risk of manual contact with radioactive source-related components.

[0038] like Figure 7 As shown, the tightening unit 2 includes a mounting base 21, a slider 22 and a servo motor 23. The mounting base 21 is set on the processing production line of the radiation source core. The slider 22 is slidably connected to one side of the mounting base 21, and the servo motor 23 is fixedly installed on the upper end of the mounting base 21.

[0039] The mounting base 21 is rotatably connected to a lead screw. One end of the lead screw is fixedly connected to the movable end of the servo motor 23. The outer thread of the lead screw is connected to the slider 22. The servo motor 23 is existing technology, and the model of the servo motor 23 is 01113977-wxstep. When the controller is turned on, the controller controls the movable end of the servo motor 23 to rotate, which drives the lead screw to rotate. Since the outer thread of the lead screw is connected to the slider 22, the rotation of the lead screw will drive the slider 22 to move along the lead screw.

[0040] Two sets of photoelectric switches 24 are installed on one side of the mounting base 21. The two sets of photoelectric switches 24 are arranged parallel to each other. One side of the slider 22 is fixedly connected to one end of the photosensitive film 25. The other end of the photosensitive film 25 is used to sense the execution end of either photoelectric switch 24. The photoelectric switch 24 is existing technology, and the model of the photoelectric switch 24 is EE-SX672. A lead screw is rotatably connected inside the mounting base 21. One end of the lead screw is fixedly connected to the moving end of the servo motor 23. The outer thread of the lead screw is connected to the slider 22. When the controller is turned on, the photoelectric switches 24 can determine the position of the slider 22 by sensing the position of the photosensitive film 25. The two photoelectric switches 24 can determine the position of the screw head 27, which is convenient for accurately positioning the density source and accurately screwing the density source to the upper end of the radiation source core.

[0041] like Figure 7 As shown, the tightening unit 2 also includes a rotating shaft 26, a screwing head 27, and a rotating motor 28. The rotating motor 28 is fixedly installed on the upper end of the slider 22. The movable end of the rotating motor 28 is fixedly connected to the upper end of the rotating shaft 26. The outer periphery of the rotating shaft 26 is rotatably connected inside the slider 22. The lower end of the rotating shaft 26 is fixedly connected to the screwing head 27. The screwing head 27 is located above the radioactive source core transported from the upstream workstation.

[0042] When the tightening unit 2 is working, it first waits for the material distribution unit 1 to transfer the density source to the preset handover position. The servo motor 23 starts and drives the lead screw in the mounting base 21 to rotate, causing the slider 22 to slide vertically along the mounting base 21. The photosensitive film 25 on one side of the slider 22 moves with the slider. When a set of photoelectric switches 24 on the mounting base 21 is triggered, it is determined that the screwing head 27 has descended to the height of docking with the density source and the source core. The slider 22 continues to move downward, and the screwing head 27 presses down on the density source and squeezes the density source out of the clamp 135, and presses the density source down to the upper end of the radiation source core. Then the rotating motor 28 starts and drives the rotating shaft 26 and the lower screwing head 27 to rotate to perform the tightening operation. After the tightening is completed, the rotating motor 28 stops, and the servo motor 23 drives the slider 22 to drive the screwing head 27 to rise and reset.

[0043] The working process of a feeding device for a radioactive source density source:

[0044] After the upstream process delivers the radiation source core to the designated location, multiple density sources 3 are pre-stored in the loading groove of the first support plate 131 in the material preparation assembly 13. The density sources 3 are placed sequentially in the loading groove of the first support plate 131, and the loading groove is connected to the arc groove of the second support plate 136. The third cylinder 134 of the receiving part drives the clamp 135 to move to the receiving position close to the arc groove, and the clamp 135 is slidably connected to the square hole of the second support plate 136. The movable end of the second cylinder 132 drives the pusher block 133 to slide along the loading groove, pushing the density sources 3 in the loading groove sequentially to the arc groove, and then into the clamping end of the clamp 135. Then the third cylinder 134 extends, pushing the clamp 135 to slide in the square hole, using the plastic elasticity of the clamp 135 to clamp the density sources 3. Since the distribution plate 123 is fixedly connected to the outside of the second support plate 136, the first cylinder 121 drives the distribution plate 123 along the slide block 1. When cylinder 22 slides, it will drive the second support plate 136 to move to one side of the tightening unit 2, completing the conveying preparation of the density source 3. When the tightening head of the tightening unit 2 moves down and locks the density source 3, the movable end of the second cylinder 132 retracts, squeezing the density source 3 out of the clamp 135. Then the tightening unit 2 works, and the servo motor 23 drives the lead screw in the mounting base 21 to rotate, causing the slider 22 to drive the screwing head 27 to descend. When the photosensitive film 25 on one side of the slider 22 triggers the photoelectric switch 24, the screwing head 27 reaches the docking height, squeezing the density source 3 out of the clamp 135 and pressing it on the radiation source core. The rotating motor 28 drives the rotating shaft 26 and the screwing head 27 to rotate to complete the tightening. After tightening, the rotating motor 28 stops, the servo motor 23 drives the slider 22 to reset, and the material distribution unit 1 also drives the pusher block 133 and the clamp 135 to return to their positions under the action of the first cylinder 121 and the second cylinder 132, waiting for the next feeding cycle.

[0045] The control method in this embodiment is controlled by a controller. The controller circuit can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this document is mainly used to protect mechanical devices, and the control method and circuit connection will not be explained in detail here.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
