Description

Technical Field

[0001] This invention belongs to the field of radioactive source assembly, and in particular relates to an assembly table for a radioactive source. Background Technology

[0002] In the field of radioactive source assembly, due to the radioactivity of radioactive sources, the safety, accuracy, and stability requirements of the assembly process are extremely high. Traditional radioactive source assembly mostly relies on simple tooling, which has obvious shortcomings. Simple tooling lacks integrated design and requires multiple transfers of the radioactive source to complete processes such as receiving, shell loading and unloading, source core transportation and maintenance. This is not only inefficient, but also prone to insufficient assembly accuracy due to vibration or positioning deviation during the transfer process. Moreover, existing equipment has not optimized vibration reduction and protection structures for the special needs of radioactive source assembly. External vibration or internal component movement vibration can easily affect precision operation, thereby reducing assembly quality and even causing radioactive safety hazards. It is difficult to meet the requirements of efficient, accurate and safe assembly of radioactive sources. Therefore, an integrated radioactive source assembly platform is needed to meet the assembly work of radioactive source cores. Summary of the Invention

[0003] In view of this, the present invention aims to provide an assembly platform for a radioactive source to solve the problem of low work efficiency caused by the need to change multiple devices when performing different operations on a radioactive source in the prior art.

[0004] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0056] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0057] like Figure 1 and Figure 2As shown, an assembly table for a radioactive source includes a housing 1. Inside the housing 1 are a rotating support platform 2, a core clamping device 3, a six-axis robotic arm 4, and a turntable assembly device 5. The rotating support platform 2, the six-axis robotic arm 4, and the turntable assembly device 5 are sequentially arranged along the direction of movement of the radioactive source within the housing 1. A set of core clamping devices 3 is arranged on each side of the six-axis robotic arm 4, and the two sets of core clamping devices 3 are parallel to each other. The rotating support platform 2 is used to support the entire radioactive source; the core clamping device 3 is used to install or remove the radioactive source casing; the six-axis robotic arm 4 is used to transport the radioactive source core; and the turntable assembly device 5 is used to maintain the radioactive source core. The six-axis robotic arm 4 is existing technology, model ER20B-1760. By providing anti-vibration feet 11, the shaking of the entire device during operation can be reduced, protecting internal precision components and extending the service life of the equipment.

[0058] like Figure 3 As shown, the rotating platform 2 includes a rotating platform body 21. The rotating platform body 21 is installed inside the housing 1. The storage tank 22 and the density source tank 23 are placed on the upper end of the rotating platform body 21. The rotating platform body 21 includes a rotating disk 211, casters 212, a slewing support 213 and a drive unit 214. The lower end of the slewing support 213 is fixedly connected inside the housing 1. The upper end of the slewing support 213 is rotatably connected to the rotating disk 211. Multiple casters 212 are arranged circumferentially at the lower end of the rotating disk 211. The outer periphery of each caster 212 is rolledly connected inside the housing 1. The drive unit 214 is arranged in the middle of the rotating disk 211. The drive unit 214 is used to drive the rotating disk 211 to rotate.

[0059] like Figure 4-6 As shown, the drive unit 214 includes a motor base 2141, a first servo motor 2142, a first gear 2143, and a motor cover 2144. The first servo motor 2142 is fixedly installed inside the housing 1 via the motor base 2141. The motor cover 2144 is sleeved around the first servo motor 2142. The output shaft of the first servo motor 2142 is fixedly sleeved around the first gear 2143. The inner ring of the rotating disk 211 is provided with an internal gear. The outer ring of the first gear 2143 meshes with the inner gear. The first servo motor 2142 is existing technology, and its model is MS1H4-75B30CB-T331R. When the controller is turned on, the controller drives the first servo motor 2142 to rotate, which in turn drives the first gear 2143 to rotate. Under the action of gear meshing, the rotating disk 211 will rotate, which will drive the storage tank 22 and density source tank 23 placed above to rotate, so as to better cooperate with the six-axis robotic arm 4 to pick up the source core.

[0060] like Figure 7As shown, the rotary table body 21 also includes an induction plate 215, an origin induction switch 216, and an origin induction base 217. The origin induction switch 216 is fixedly installed on the periphery of the rotary support base 213 through the origin induction base 217. One end of the induction plate 215 is fixedly connected to the lower end of the rotary disk 211. The other end of the induction plate 215 is used as the execution end of the origin induction switch 216. The origin induction switch 216 is existing technology, and the model of the origin induction switch 216 is Omron EE-SX671. When the rotary support table 2 is started, the drive unit 214 drives the rotary disk 211 to rotate, and the induction plate 215 rotates synchronously with the rotary disk 211.

[0061] When the sensing plate 215 rotates to the execution end of the origin sensing switch 216, the origin sensing switch 216 detects the signal of the sensing plate 215 and then sends an origin trigger signal to the assembly table control system. After receiving the signal, the control system determines that the rotating disk 211 has reached the preset origin position, and then controls the first servo motor 2142 to adjust the speed or stop rotating to complete the origin calibration of the rotating disk 211. The origin calibration component is set to ensure that the rotating disk 211 can return to the fixed origin after each rotation, so that the storage tank 22 and the density source tank 23 are always within the grasping range of the six-axis robotic arm 4, avoiding the failure of the robotic arm to grasp or the collision of the source core due to the positioning deviation of the rotating disk.

[0062] like Figure 8 As shown, the source core clamping device 3 includes a clamping seat 31, a horizontal displacement component 32, a vertical displacement component 33, a gripper 34, and a support plate 35. The clamping seat 31 and the horizontal displacement component 32 are installed in the housing 1 through the support plate 35, and the clamping seat 31 is located on one side of the horizontal displacement component 32. The movable end of the horizontal displacement component 32 is fixedly connected to the vertical displacement component 33, and the movable end of the vertical displacement component 33 is fixedly connected to the gripper 34. The horizontal displacement component 32, which can move horizontally, and the vertical displacement component 33, which can move vertically, are provided, which allows the gripper 34 to move in a two-dimensional plane, thereby enhancing the flexibility of the gripper 34.

[0063] like Figure 9As shown, the clamping seat 31 includes a first clamp 311, a second clamp 312, a support rod 313, a first cylinder 314, and multiple supports 315. The four supports 315 are arranged in pairs facing each other on the upper end of the support plate 35. A support rod 313 is arranged between every two supports 315. The outer peripheries of the two support rods 313 are slidably connected to one end of the first clamp 311. The first clamp 311 and the second clamp 312 are arranged facing each other. The lower end of the second clamp 312 is fixedly connected to the upper end of the support plate 35. The first cylinder 314 is fixedly mounted on the support plate 35 via the supports 315 and is located on the side close to the first clamp 311. The first clamp 311 is fixedly connected to the movable end of the first cylinder 314. Grooves are provided on the inner sides of both the first clamp 311 and the second clamp 312, and these grooves are used to abut against the outer periphery of the source core. The first cylinder 314 is... In the existing technology, the first cylinder 314 is model SDAS-25x2020. When the six-axis robotic arm 4 transports the radioactive source core with its outer shell to the clamping seat 31, the six-axis robotic arm 4 places the radioactive source in the groove between the first clamp 311 and the second clamp 312. The first cylinder 314 is extended by controlling the extension of the first cylinder 314. The movable end of the first cylinder 314 pushes the first clamp 311 to slide along the support rod 313 towards the second clamp 312 until the inner grooves of the first clamp 311 and the second clamp 312 are completely in contact with the outer periphery of the radioactive source shell. At this time, the radioactive source shell is fixed, and the clamping and positioning are completed. The clamping seat 31 is set up to accommodate radioactive source shells of different diameters. It can meet the assembly requirements of various specifications of radioactive sources without replacing the entire component, thereby improving the applicability of the assembly table and reducing the equipment modification cost.

[0064] like Figure 9 As shown, the horizontal displacement component 32 includes a first mounting base 321, a first slider 322, and a second servo motor 323. The first mounting base 321 is fixedly mounted on the upper end of the support plate 35. One side of the first mounting base 321 is slidably connected to one end of the first slider 322, and the other end of the first slider 322 is fixedly connected to the vertical displacement component 33. The second servo motor 323 is fixedly mounted on one side of the outside of the first mounting base 321. The second servo motor 323 is existing technology, and its model is MS1-R. A first lead screw is rotatably installed inside the first mounting base 321. The output shaft of the second servo motor 323 is fixedly connected to one end of the first lead screw. The outer thread of the first lead screw is connected to the first slider 322. The controller controls the rotation of the second servo motor 323, which in turn drives the first lead screw to rotate. Since the outer thread of the first lead screw is connected to the first slider 322, during the rotation of the first lead screw, the first slider 322 moves along the direction of the first lead screw, which in turn drives the vertical displacement component 33 to move horizontally.

[0065] Two sets of first photoelectric switches 3211 are arranged on one side of the first mounting base 321, and the two sets of first photoelectric switches 3211 are arranged parallel to each other. One side of the first slider 322 is fixedly connected to one end of the first photosensitive film 3221. The other end of the first photosensitive film 3221 is used to sense the recognition end of any first photoelectric switch 3211. The first photoelectric switch 3211 is existing technology, and the model of the first photoelectric switch 3211 is EE-SX672. The second servo motor 323 drives the first slider 322 to move. When the first photosensitive film 3221 moves to the recognition end of one of the sets of first photoelectric switches 3211, the first photosensitive film 3221 moves with the slider during horizontal displacement. When it reaches the recognition end of the corresponding set of first photoelectric switches 3211 at the target position, two sets of first photoelectric switches 3211 and first photosensitive film 3221 are set up. Through non-contact sensing, the position of the first slider 322 can be detected, and the signal can be fed back to the control system to control the start and stop of the second servo motor 323, avoiding displacement deviation and ensuring that the gripper 34 is aligned with the operating reference, which can improve the assembly accuracy of the source core.

[0066] like Figure 10 As shown, the vertical displacement assembly 33 includes a second mounting base 331, a third servo motor 332, and a second slider 333. The second mounting base 331 is fixedly mounted on one side of the first slider 322, and the second slider 333 is slidably connected to one side of the second mounting base 331. A gripper 34 is rotatably arranged inside the second slider 333. The third servo motor 332 is fixedly mounted on the upper end of the second mounting base 331. Two sets of second photoelectric switches 3311 are arranged on one side of the second mounting base 331, and the two sets of second photoelectric switches 3311 are arranged parallel to each other. One end of a second photosensitive film 3331 is fixedly connected to one side of the second slider 333, and the other end of the second photosensitive film 3331 is used to sense the execution end of any second photoelectric switch 3311. A second lead screw is rotatably arranged inside the second mounting base 331, and the output shaft of the third servo motor 332 is fixedly connected to one end of the second lead screw. The second slider 333 is threadedly connected to the outer periphery of the second lead screw.

[0067] like Figure 12As shown, the gripper 34 includes a pneumatic chuck 341, a rotating shaft, and a first rotary motor 342. The first rotary motor 342 is fixedly mounted on the upper end of the second slider 333. The movable end of the first rotary motor 342 is fixedly connected to the upper end of the rotating shaft. The outer periphery of the rotating shaft is rotatably disposed within the second slider 333. The first rotary motor 342 is prior art, and its model is ATO-60SY-M01330S. The pneumatic chuck 341 is fixedly mounted on the lower end of the rotating shaft. The pneumatic chuck 341 is prior art, and its model is DH-Robotics. RGI, the controller controls the vertical displacement component 33 to move downwards and approach the radioactive source core. The pneumatic chuck 341 clamps the outer shell of the radioactive source core. At this time, the controller controls the first rotary motor 342 to rotate and drive the outer shell of the radioactive source core to rotate, thus removing the outer shell of the radioactive source core. When installing the outer shell of the radioactive source core, the controller repeats the above operation, first controlling the first rotary motor 342 to rotate and drive the outer shell of the radioactive source core to rotate, and then releasing the pneumatic chuck 341 to lower the outer shell of the radioactive source core.

[0068] like Figure 12 As shown, a test tube holder 6 is also provided inside the housing 1. The test tube holder 6 is located between the turntable assembly device 5 and the six-axis robotic arm 4. The test tube holder 6 is used to temporarily store the source core. The test tube holder 6 can connect the turntable assembly device 5 and the source core clamping device 3, making it convenient for the turntable assembly device 5 to take out the source core.

[0069] like Figure 12 As shown, the turntable assembly device 5 includes a steel brush station 51, a go gauge station 52, a no-go gauge station 53, a vision station 54, an adhesive dispensing station 55, a source station 56, a head removal station 57, and a turntable 58. The turntable 58 is installed inside the housing 1. The steel brush station 51, go gauge station 52, no-go gauge station 53, vision station 54, adhesive dispensing station 55, source station 56, and head removal station 57 are evenly distributed around the turntable 58.

[0070] like Figures 13-15 As shown, multiple clamps 581 are evenly distributed circumferentially on the upper end of the rotating disk 58. The clamps 581 are used to clamp and rotate the radiation source core. Multiple clamps 581 and a robotic gripper are evenly distributed circumferentially on the upper end of the rotating disk 58. A clamping assembly 59 is provided below each clamp 581. The clamping assembly 59 is installed on the production line. The clamping assembly 59 is used to rotate the clamp 581 and the radiation source core. The clamps 581 are used to clamp the radiation source core.

[0071] The rotating disk 58 includes an indexing disk 583, a cam divider 584, a rotary servo motor 585, and a fixed disk 586. The fixed disk 586 is fixedly installed inside the housing 1. The indexing disk 583 is rotatably sleeved around the fixed disk 586. The cam divider 584 is installed at the lower end of the fixed disk 586. The output shaft of the cam divider 584 is fixedly connected to the indexing disk 583. The rotary servo motor 585 is fixedly installed on one side of the cam divider 584. The output shaft of the rotary servo motor 585 and the input shaft of the cam divider 584 are connected by a synchronous belt to form a transmission structure. The rotary servo motor 585 is existing technology, and its model number is 01113977-wxstep. The robotic gripper is existing technology, and its model number is RM01. The cam divider 584 is existing technology, and its model number is 45DF.

[0072] like Figure 16 As shown, the input shaft of the cam divider 584 is fixedly sleeved with an induction disk 5841. The notch in the induction disk 5841 is used to sense the actuator of the zero-position switch 5842. The zero-position switch 5842 is fixedly installed on the outer wall of the cam divider 584. The zero-position switch 5842 is existing technology; its model is EE-SX671. The zero-position switch 5842, in conjunction with the induction disk 5841, enables zero-position calibration, ensuring consistent starting positions for each rotation, guaranteeing batch operation stability, and improving the efficiency of radioactive source core maintenance.

[0073] like Figure 17 and Figure 18 As shown, the indexing plate 583 has multiple mounting slots 5831 circumferentially arranged on its upper end. Each mounting slot 5831 contains a clamping sleeve 581, and a clamping assembly 59 is arranged below each clamping sleeve 581. The clamping assembly 59 can drive the clamping sleeve 581 to rotate. The clamping sleeve 581 includes a clamping body 5811, a bearing 5812, a pull rod 5813, a pull block 5814, and a second gear 5815. A sleeve 5816 is arranged around the clamping body 5811, and the sleeve 5816 rotates through the bearing 5812. Set within the mounting slot 5831, the jacket body 5811 can move axially relative to the sleeve 5816, and the upper outer periphery of the jacket body 5811 is engaged with the upper inner ring of the sleeve 5816. The lower end of the jacket body 5811 is fixedly connected to one end of the pull rod 5813, and the other end of the pull rod 5813 is rotatably connected to the pull block 5814. The pull block 5814 can be engaged within the clamping assembly 59. The outer periphery of the pull rod 5813 is fixedly sleeved with the second gear 5815, which can mesh with the clamping assembly 59.

[0074] like Figure 17 and Figure 18As shown, the clamping assembly 59 includes a pull-down base 591, a second cylinder 592, and a fourth servo motor 593. The outer periphery of the second gear 5815 can mesh with the output gear of the fourth servo motor 593. The fourth servo motor 593 is fixedly mounted on the production line. The second cylinder 592 is fixedly mounted on one side of the fourth servo motor 593. The movable end of the second cylinder 592 is connected to the closed end of the pull-down base 591. The other end of the pull-down base 591 is used to clamp the outer periphery of the pull block 5814. The second cylinder 592 is prior art, and its model is MD25x20-S20. The fourth servo motor 593 is prior art, and its model is 57CM13. The clamping body 5811 is prior art, and its model is Huo. The control system of the Huffman ER13835010900 sends a command to the second cylinder 592. The movable end of the second cylinder 592 pulls the pull-down seat 591, which drives the pull rod 5813 to slide. This causes the inner ring of the jacket body 5811 to contract and tightly fit the outer periphery of the radiation source core within the sleeve 5816, firmly clamping the source core and preventing displacement or shaking during subsequent transport and operation. The fourth servo motor 593 starts, and its output gear meshes with the second gear 5815 on the periphery of the jacket body 5811, driving the jacket body 5811 and the internal source core to rotate synchronously within the mounting groove 5831. The jacket 581 is designed to clamp the radiation source core and rotate it to cooperate with subsequent workstation operations, improving work efficiency and the overall automation level of the device.

[0075] like Figure 19 As shown, the steel brush station 51 includes a third mounting base 511, a third slider 512, and a fifth servo motor 513. The third mounting base 511 is installed inside the housing 1. The third slider 512 is slidably connected to one side of the third mounting base 511. The fifth servo motor 513 is fixedly installed at the upper end of the third mounting base 511. The fifth servo motor 513 is existing technology, and its model number is 01113977-wxstep. A third lead screw is rotatably connected inside the third mounting base 511. One end of the third lead screw is fixedly connected to the movable end of the fifth servo motor 513. The fifth servo motor 513 is fixedly installed at the upper end of the third mounting base 511. The outer thread of the third lead screw is connected to the third slider 512. When the fifth servo motor 513 is started, it drives the third lead screw inside the third mounting base 511 to rotate. Since the third lead screw is threadedly connected to the third slider 512, the third slider 512 slides vertically along the third mounting base 511, and drives the steel brush installed at the upper end to move to the upper end of the source core.

[0076] like Figure 19As shown, two sets of third photoelectric switches 5111 are installed on one side of the third mounting base 511. The two sets of third photoelectric switches 5111 are arranged parallel to each other. One side of the third slider 512 is fixedly connected to one end of the third photosensitive film 5121. The other end of the third photosensitive film 5121 is used to sense the execution end of any third photoelectric switch 5111. When the photosensitive film triggers one set of third photoelectric switches 5111 on the third mounting base 511, the control system determines that the steel brush 514 has descended to a preset height that is flush with the outer teeth of the source core. The fifth servo motor 513 stops rotating, and the vertical position calibration is completed. The third photoelectric switch 5111 is existing technology, and the model of the third photoelectric switch 5111 is EE-SX672.

[0077] Figure 19 As shown, the steel brush station 51 also includes steel brushes 514, a steel brush cover 515, a third gear 517, and a second rotating motor 518. Two steel brushes 514 are rotatably connected inside the third slider 512. The two steel brushes 514 are arranged parallel to each other. One end of each steel brush 514 is fixedly sleeved with the third gear 517. The outer periphery of each third gear 517 meshes with the output gear of the second rotating motor 518. The second rotating motor 518 is fixedly mounted on the upper end of the third slider 512. The outer periphery of the third slider 512 is fixedly sleeved with the steel brush cover 515. The second rotating motor 518 is existing technology. The second rotating motor 518, model ATO-60SY-M01330S, is activated by turning on the controller. The controller controls the second rotating motor 518 to rotate, which in turn drives the steel brush 514 to rotate synchronously. This cleans both sides of the upper end of the core. The collaborative cleaning method using high-speed rotation of the two steel brushes can clean the outer teeth of the core without dead angles. Compared with manual cleaning or cleaning with a single steel brush, it can thoroughly remove stubborn impurities from the surface of the outer teeth and ensure that the tooth shape is intact and the surface is smooth. This provides a reliable foundation for subsequent inspection of go gauges and no-go gauges and for the core installation, reducing assembly failures caused by incomplete cleaning.

[0078] like Figure 19 and Figure 20 As shown, the lower end of the third mounting base 511 is connected to the suction end of the dust hood 519, the outlet end of the dust hood 519 is connected to an external vacuum cleaner, the inner side of the steel brush cover 515 is equipped with an air nozzle 516, the air inlet end of the air nozzle 516 is connected to an external air pump, and the air jet end of the air nozzle 516 faces the brush head of the steel brush 514. The vacuum cleaner is existing technology, and the model of the vacuum cleaner is Weideer WX-3610. The air pump is existing technology, and the model of the air pump is Yufeng 2RB410-7H1 / 380V.

[0079] like Figure 13 and Figure 21As shown, the go gauge station 52 includes a go gauge drive unit and a go gauge sleeve 526. The go gauge drive unit is fixedly installed inside the housing 1, and the lower end of the go gauge drive unit is rotatably connected to the go gauge sleeve 526. The no-go gauge station 53 includes a no-go gauge drive unit and a no-go gauge sleeve. The no-go gauge drive unit is fixedly installed inside the housing, and the lower end of the go gauge drive unit is rotatably connected to the no-go gauge sleeve.

[0080] The go gauge drive unit and the no-go gauge drive unit have the same structure. The go gauge drive unit includes a fourth mounting base 521, a fourth slider 522 and a sixth servo motor 523. The fourth mounting base 521 is provided inside the housing 1. The fourth slider 522 is slidably connected to one side of the fourth mounting base 521. The sixth servo motor 523 is fixedly installed on the upper end of the fourth mounting base 521.

[0081] The go gauge drive unit also includes a third rotary motor 524 and two sets of thread gauge concentric clamps 525. A go gauge sleeve 526 or a no-go gauge sleeve is rotatably installed inside the fourth slider 522. The upper end of the go gauge sleeve 526 or the no-go gauge sleeve is fixedly connected to the output shaft of the third rotary motor 524. The third rotary motor 524 is fixedly installed on the upper end of the fourth slider 522. A set of thread gauge concentric clamps 525 is provided on both sides of the go gauge sleeve 526 or the no-go gauge sleeve. The two sets of thread gauge concentric clamps 525 are arranged opposite each other. Each set of thread gauge concentric clamps 525 is fixedly installed on the fourth slider 522. The third rotary motor 524 is prior art. The model of the third rotary motor 524 is ATO-60SY-M01330S.

[0082] The thread gauge concentric clamp 525 includes a third cylinder 5251 and a chuck 5252. A fourth slider 522 is fixedly mounted on the third cylinder 5251. The movable end of the third cylinder 5251 is fixedly connected to the chuck 5252. The inner side of the chuck 5252 is used to abut against the outer periphery of the go gauge sleeve 526 shaft.

[0083] When the gauge station 52 is working, it first waits for the rotating disk 58 to drive the clamping sleeve 581, which clamps the source core, to move to the corresponding position. The indexing disk 583 stops rotating. Then, the sixth servo motor 523 drives the fourth lead screw in the fourth mounting base 521 to rotate, causing the fourth slider 522 to move vertically. When the fourth photosensitive film 5221 on one side of the fourth slider 522 triggers the fourth photoelectric switch 5211, the fourth slider 522 stops moving, aligning the gauge sleeve 526 with the source core. Then, the third cylinder 5251... The chuck 5252 is pushed to clamp the go gauge sleeve 526 shaft to ensure concentricity. The third rotary motor 524 drives the go gauge sleeve 526 to rotate. At the same time, the sixth servo motor 523 drives the fourth slider 522 to move down, so that the go gauge sleeve 526 engages with the external thread of the source core to complete the go gauge inspection. After the inspection is completed, the third rotary motor 524 stops, the third cylinder 5251 drives the chuck 5252 to release, the sixth servo motor 523 drives the fourth slider 522 to reset, and the rotating disk 58 transfers the source core to the next workstation.

[0084] like Figure 21As shown, the thread gauge concentric clamp 525 includes a third cylinder 5251 and a chuck 5252. A fourth slider 522 is fixedly mounted on the third cylinder 5251. The movable end of the third cylinder 5251 is fixedly connected to the chuck 5252. The inner side of the chuck 5252 is used to abut against the outer periphery of the GO gauge sleeve 526 shaft. The third cylinder 5251 is existing technology, and its model is MD25x20-S20. The controller controls the extension of the third cylinders 5251 on both sides, which in turn drives the chucks on both sides to extend, determining the position of the GO gauge sleeve 526 and ensuring that the GO gauge sleeve 526 can be accurately positioned. The gauge sleeve is placed on the upper end of the source core for testing. Under the action of the third cylinder 5251, the chuck 5252 of the concentric clamp 525 firmly clamps the shaft of the go gauge sleeve 526. The concentric clamp 525 is designed to prevent the go gauge sleeve from shaking or shifting during rotation and engagement with the source core. This not only ensures the stability of the testing process and makes the contact between the gauge and the outer teeth of the source core more uniform and the testing process more stable, but also avoids unnecessary scratching or damage to the outer teeth of the source core caused by the gauge shaking, thus protecting the integrity of the source core and ensuring that the testing work will not have a negative impact on the quality of the source core.

[0085] like Figure 22 The visual workstation 54 shown includes an infrared camera 541 and a backlight 542. The infrared camera 541 is fixedly mounted on the upper end of the mounting plate 586, and the infrared emitting end of the infrared camera 541 faces the backlight 542. The backlight 542 is fixedly mounted inside the housing 1. The infrared camera 541 is existing technology, and the model of the infrared camera 541 is Fluke TI401-PRO-KIT. The backlight 542 is existing technology, and the model of the backlight 542 is FPD-6060T.

[0086] When the vision workstation 54 is working, it first waits for the rotating disk 58 to drive the clamping sleeve 581, which clamps the radiation source core, to be transferred to the corresponding detection position. The indexing disk 583 stops rotating. Then, the fourth servo motor 593 of the clamping sleeve 581 drives the clamping sleeve 581 and the internal source core to rotate slowly through the second gear 5815. At the same time, the backlight 542 is turned on to provide uniform illumination for the source core. The infrared camera 541 on the upper end of the fixed disk 586 is started. Its infrared emitter is aimed at the rotating source core to capture images of the source core surface in real time and transmit them to the control system. After the source core completes the rotation and image capture, the control system analyzes the image to determine whether the source core meets the standard. After the detection is completed, the infrared camera 541 stops working, the backlight 542 is turned off, and the control system analyzes the image to determine whether the source core meets the standard. After the determination is completed, the rotating disk 58 transfers the source core to the next workstation, and the vision workstation 54 enters the standby state.

[0087] A vision workstation 54 is set up, which uses an infrared camera 541 and a backlight 542. The backlight can provide a uniform and stable lighting environment for the source core, eliminating the interference of reflection or shadow on the source core surface on the imaging. This allows the infrared camera 541 to clearly capture details such as the integrity of the external teeth and surface defects of the source core. Compared with manual visual inspection, it can avoid misjudgment caused by eye fatigue and subjective judgment bias, ensuring the objectivity and accuracy of the inspection results, and screening out qualified source cores for subsequent processes.

[0088] like Figure 23 The dispensing station 55 shown includes a fifth mounting base 551, a fifth slider 552, and a seventh servo motor 553.

A fifth lead screw is rotatably connected inside the fifth mounting base 551. One end of the fifth lead screw is fixedly connected to the movable end of the seventh servo motor 553. The outer thread of the fifth lead screw is connected to the fifth slider 552.

[0089] like Figure 23 As shown, the dispensing station 55 also includes a needle holder 554, a fifth cylinder 555, a needle 556, and a fourth cylinder 557. The fourth cylinder 557 is fixedly mounted on one side of the fifth slider 552. The movable end of the fourth cylinder 557 is fixedly connected to the needle holder 554. The fifth cylinder 555 is fixedly mounted on one end of the needle holder 554. The other end of the needle holder 554 holds the needle 556. The movable end of the fifth cylinder 555 is used to push the piston of the needle 556. The fourth cylinder 557 is prior art, and its model number is MY3A. The fifth cylinder 555 is prior art, and its model number is MD25x20-S20.

[0090] When the dispensing station 55 is working, it first waits for the rotating disk 58 to drive the clamping sleeve 581, which holds the radiation source core, to move to the corresponding dispensing position. The indexing disk 583 stops rotating. Then, the seventh servo motor 553 drives the fifth lead screw in the fifth mounting base 551 to rotate, causing the fifth slider 552 to move vertically. When the fifth slider 552 moves to align the needle tube 556 with the preset dispensing position of the source core, the fourth cylinder 557 pushes the needle tube seat 554 to adjust the horizontal position of the needle tube 556, ensuring that the needle tube nozzle accurately fits the dispensing point of the source core. Then, the movable end of the fifth cylinder 555 pushes the needle tube... The piston of tube 556 evenly squeezes the adhesive from the syringe to the designated position of the source core. After dispensing, the fifth cylinder 555 resets, the seventh servo motor 553 drives the fifth slider 552 to lift the syringe 556 to reset, the fourth cylinder 557 drives the syringe seat 554 back to its original position, and the rotating disk 58 transfers the source core to the next workstation. The dispensing workstation 55 is set up to ensure that the adhesive is evenly and stably coated on the designated position of the source core, avoiding the position deviation and uneven dispensing problems of manual dispensing, ensuring dispensing accuracy, and providing a reliable guarantee for the subsequent connection or sealing of the source core with other components.

[0091] like Figure 25 As shown, the source station 56 includes a material distribution unit 561 and a tightening unit 562. The material distribution unit 561 is set on the processing production line of the radioactive source core, and the tightening unit 562 is set on one side of the material distribution unit 561. The tightening unit 562 is fixedly installed on the production line. The material distribution unit 561 is used to transport the density source 56137, and the tightening unit 562 is used to install the density source 56137 on the source core.

[0092] The material distribution unit 561 includes a bracket 5611, a material distribution component 5612, and a material preparation component 5613.

One end of the material distribution component 5612 is fixedly connected to the material preparation component 5613. The material preparation component 5613 is located on one side of the tightening unit 562. The material distribution unit 561 can work closely with other workstations on the radioactive source processing production line to accurately transfer the density source 56137 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.

[0093] The material dispensing assembly 5612 includes a material dispensing cylinder 56121, a slide block 56122, and a material dispensing plate 56123. Two slide blocks 56122 are fixedly installed on the upper end of the bracket 5611. The two slide blocks 56122 are arranged parallel to each other, and each slide block 56122 is slidably connected to the periphery of the material dispensing plate 56123. One end of the material dispensing plate 56123 is fixedly connected to the movable end of the material dispensing cylinder 56121, and the other end of the material dispensing plate 56123 is fixedly connected to the material preparation assembly 5613. The material dispensing cylinder 56121 is fixedly installed on the upper end of the bracket 5611. The material dispensing cylinder 56121 is prior art, and its model is MD25x20-S20.

[0094] The material preparation assembly 5613 includes a first support plate 56131, a second support plate 56136, a pushing part, and a receiving part. The first support plate 56131 is fixedly installed on the upper end of the bracket 5611. A pushing part is provided at one end of the first support plate 56131, and the other end of the first support plate 56131 abuts against one end of the second support plate 56136. A receiving part is provided at the other end of the second support plate 56136. A material distribution plate 56123 is fixedly connected to the outer side of the second support plate 56136. A feeding groove is provided on the first support plate 56131, and an arc-shaped groove is provided on the second support plate 56136. The feeding groove can communicate with the arc-shaped groove. Multiple density sources 56137 are placed in the feeding groove in sequence. The pushing part is used to feed the density sources 56137 into the receiving part in sequence along the direction of the feeding groove.

[0095] The pushing part includes a pushing cylinder 56132 and a pushing block 56133. The pushing cylinder 56132 is fixedly installed at one end of the first support plate 56131, and the moving end of the pushing cylinder 56132 is fixedly connected to the pushing block 56133. The periphery of the pushing block 56133 is slidably connected to the feeding groove. The receiving part includes a receiving cylinder 56134 and a receiving clamp 56135. The receiving cylinder 56134 is installed at one end of the second support plate 56136, and the moving end of the receiving cylinder 56134 is fixedly connected to one end of the receiving clamp 56135. The other end of the receiving clamp 56135 is provided with a clamping groove for clamping the density source 56137. The receiving clamp 56135 is a plastic elastic clamp. The push cylinder 56132 is prior art, and the model of the push cylinder 56132 is MD25x20-S20. The receiving cylinder 56134 is prior art, and the model of the receiving cylinder 56134 is MD25x20-S20.

[0096] Multiple density sources 56137 are sequentially placed in the feeding trough of the first support plate 56131. ​​One end of the first support plate 56131 abuts against one end of the second support plate 56136, connecting the feeding trough with the arc-shaped groove of the second support plate 56136. The receiving cylinder 56134 of the receiving unit drives the receiving clamp 56135 to move to a receiving position close to or away from the arc-shaped groove.

[0097] Furthermore, the receiving clamp 56135 is slidably connected to the square hole of the second support plate 56136. Subsequently, the pushing unit is activated, and the movable end of the pushing cylinder 56132 drives the pushing block 56133 to slide along the feeding groove, pushing the density source 56137 in the feeding groove to the arc-shaped groove in sequence, and then into the clamping end of the receiving clamp 56135. The receiving clamp 56135 elastically clamps the density source 56137. Since the distribution plate 56123 is fixedly connected to the outside of the second support plate 56136, when the distribution cylinder 56121 drives the distribution plate 56123 to slide along the slide block 56122, it will drive the second support plate 56136 as a whole. Move to one side of the tightening unit 562 to complete the preparation for conveying the density source 56137. After the tightening unit 562 locks the density source 56137, push the cylinder 56132 to retract, pull the receiving clamp 56135 to release the clamped density source 56137 from the receiving clamp 56135, and wait for the next feeding cycle. The material distribution unit 561 is set up to accurately transfer the density source 56137 to the handover position that matches the tightening unit 562. It is compatible with the entire automated process of radioactive source processing, 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.

[0098] like Figure 28 As shown, the tightening unit 562 includes a sixth mounting base 5621, a sixth slider 5622, and an eighth servo motor 5623.

[0099] like Figure 28 As shown, two sets of fifth photoelectric switches 5624 are installed on one side of the sixth mounting base 5621. The two sets of fifth photoelectric switches 5624 are arranged in parallel to each other. One side of the sixth slider 5622 is fixedly connected to one end of the fifth photosensitive film 5625. The other end of the fifth photosensitive film 5625 is used to sense the actuation end of any fifth photoelectric switch 5624. The fifth photoelectric switch 5624 is prior art, and the model of the fifth photoelectric switch 5624 is EE-SX672.

[0100] like Figure 28 and Figure 29As shown, a sixth lead screw is rotatably connected inside the sixth mounting base 5621. One end of the sixth lead screw is fixedly connected to the movable end of the eighth servo motor 5623. The outer periphery of the sixth lead screw is threadedly connected to the sixth slider 5622. The tightening unit 562 also includes a tightening shaft 5626, a tightening head 5627, and a third rotary motor 5628. The third rotary motor 5628 is fixedly mounted on the upper end of the sixth slider 5622. The movable end of the third rotary motor 5628 is fixedly connected to the upper end of the tightening shaft 5626. The outer periphery of the tightening shaft 5626 is rotatably connected inside the sixth slider 5622. The lower end of the tightening shaft 5626 is fixedly connected to the tightening head 5627.

[0101] When the tightening unit 562 is working, it first waits for the material distribution unit 561 to transfer the density source 56137 to the preset handover position, and the rotating disk 58 drives the clamping sleeve 581 of the source core to transfer to the corresponding tightening station. The indexing disk 583 stops rotating, and then the eighth servo motor 5623 starts, driving the sixth lead screw in the sixth mounting base 5621 to rotate, driving the sixth slider 5622 to slide vertically along the sixth mounting base 5621. The fifth photosensitive film 5625 on one side of the sixth slider 5622 moves with the slider. When a set of fifth photoelectric switches on the sixth mounting base 5621 is triggered... At time 5624, it is determined that the screwing head 5627 has descended to the height where it aligns with the density source 56137 and the source core. The eighth servo motor 5623 stops, and then the third rotary motor 5628 starts, driving the tightening shaft 5626 and the screwing head 5627 at its lower end to rotate. After the screwing head 5627 grabs the density source 56137 conveyed by the material distribution unit 561, the eighth servo motor 5623 continues to drive the sixth slider 5622 to move slightly downward, so that the density source 56137 is aligned with the source core mounting position. The screwing head 5627 tightens the density source 56137 onto the source core. After tightening is completed, the third rotary motor 5628 stops, and the eighth servo motor 5623 drives the sixth slider 5622 to drive the screwing head 5627 to rise and reset. When the fifth photosensitive film 5625 triggers another set of fifth photoelectric switches 5624, the slider stops, and the rotating disk 58 transfers the source core to the next workstation.

[0102] like Figure 30 As shown, the head removal station 57 includes a lateral displacement component 571, a longitudinal displacement component 572, a head removal component 573, and a collection box 574. The lateral displacement component 571 is fixedly installed inside the housing 1. The longitudinal displacement component 572 is slidably connected to the upper end of the lateral displacement component 571. The head removal component 573 is slidably connected to one side of the longitudinal displacement component 572. The collection box 574 is fixedly installed inside the housing 1 and located below the head removal component 573. Both the lateral displacement component 571 and the longitudinal displacement component 572 are equipped with linear modules. The linear modules are linear motors, lead screws, or screw slides. The screw slide is existing technology, and the model of the screw slide is ZCH110. The movement of the linear modules drives the lateral displacement component 571 and the longitudinal displacement component 572 to move.

[0103] When the head removal station 57 is working, it first waits for the rotating disk 58 to drive the clamping sleeve 581, which clamps the radiation source core, to be transferred to the corresponding head removal position. The indexing disk 583 stops rotating. Then, the lateral displacement component 571 is activated, and through its internal linear module, it drives the longitudinal displacement component 572 to slide horizontally, adjusting the lateral position of the head removal 573 so that it is aligned with the head of the source core to be removed. Then, the linear module of the longitudinal displacement component 572 drives the head removal 573 to approach the source core vertically until the head removal 573 clamps the head of the source core to be removed. After that, the head removal 573 starts the disassembly action and removes the head of the source core. The waste generated during disassembly falls directly into the collection box 574 below. After disassembly is completed, the head removal 573 is released, the longitudinal displacement component 572 drives the head removal 573 to rise and reset, and the lateral displacement component 571 drives the longitudinal displacement component 572 and the head removal 573 back to the initial position. The rotating disk 58 then transfers the processed source core to the next station.

[0104] The working process of an assembly table for a radioactive source:

[0105] When installing the density source head 56137 for the new radioactive source core, the entire radioactive source is supported by the rotating support platform 2. The first servo motor 2142 inside the housing 1 is fixed by the motor base 2141. Its output shaft drives the first gear 2143 to rotate, which meshes with the gear in the inner ring of the rotating disk 211 to drive the rotating disk 211 to rotate. The casters 212 at the lower end of the rotating disk 211 roll along the housing 1 to assist in stability. At the same time, the sensing plate 215 at the lower end of the rotating disk 211 rotates with it. When the sensing plate 215 triggers the origin sensing switch 216 on the periphery of the rotary support 213, the rotating disk 211 completes the origin calibration, ensuring that the upper storage tank 22 and density source tank 23 are precisely within the grasping range of the six-axis robotic arm 4. Subsequently, the six-axis robotic arm 4 moves from the storage tank 211 to the density source tank 23. The radioactive source is picked up from the density source tank 23 and transported to one of the source core clamping devices 3. The first cylinder 314 of the source core clamping device 3 pushes the first clamp 311 to move along the support rod 313 to the second clamp 312, clamping the radioactive source shell through the grooves on both sides. At the same time, the second servo motor 323 of the horizontal displacement component 32 drives the first lead screw to move the first slider 322. The third servo motor 332 of the vertical displacement component 33 drives the second lead screw to move the second slider 333, so that the gripper 34 is aligned with the shell. The first rotation motor 342 drives the pneumatic chuck 341 to rotate, removing the shell from the source core. The six-axis robotic arm 4 then transports the source core with the shell removed to the test tube seat 6 for temporary storage or directly to the turntable assembly device 5.

[0106] When the turntable assembly device 5 is started, the servo motor 585 drives the input shaft of the cam divider 584 to rotate via a synchronous belt. The six-axis robotic arm 4 places the source core into the clamp 581 on the indexing plate 583. The second cylinder 592 pushes the pull-down seat 591 to drive the clamp 5811 to clamp the source core. Then, the servo motor 585 drives the cam divider 584 to drive the indexing plate 583 to rotate step by step, sending the source core to each station in sequence: the steel brush station 51 drives the steel brush 514 to rotate and clean the outer teeth of the source core, the dust hood 519 simultaneously sucks in the residue, the air nozzle 516 sprays air to assist in cleaning, the go gauge station 52 and the no-go gauge station 53 complete the go and no-go gauge inspection. The go gauge station 52 is used to detect the minimum size of the upper end of the radioactive source core, and the no-go gauge station 53 is used to detect the maximum size of the upper end of the radioactive source core. The backlight 542 of the vision station 54 is turned on, and the infrared camera 541 captures the image of the rotating source core and... The data is transmitted to the control system for analysis. The dispensing station 55 completes the dispensing at the top of the source core. In the material distribution unit 561 of the source station 56, the seventh cylinder 5642 pushes the pusher block 5643 to push the density source 56137 to the material distribution block 5645. The sixth cylinder 5631 drives the material distribution plate 5633 to be transferred to the tightening unit 562. The eighth servo motor 5623 of the tightening unit 562 drives the sixth lead screw to drive the sixth slider 5622 to descend. The third rotary motor 5628 drives the screwing head 5627 to tighten the density source 56137 onto the source core. After all the station operations are completed, the robotic arm gripper grabs the source core and places it in the test tube seat 6. The six-axis robotic arm 4 takes out the source core and puts it back into the source core clamping device 3. The source core clamping device 3 drives the gripper 34 to cooperate with the fixture in the reverse process to reinstall the outer shell onto the source core, completing the entire assembly and maintenance process of the radiation source.

[0107] When replacing the old density source 56137 with a new one, the old source core is received by the rotating material receiving table 2 and transferred to the turntable assembly device 5. It first passes through the disassembly station 57. The lateral displacement component 571 and the longitudinal displacement component 572 of the disassembly station 57 drive the disassembly 573 to disassemble the old density source 56137. The waste falls into the collection box 574. The above-mentioned go / no-go gauge inspection, visual inspection, glue dispensing and new source assembly are repeated in this way.

[0108] 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.

[0109] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
