DETAILED DESCRIPTION

[0024] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following embodiments or drawings are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] A thermoluminescent dosimeter automatic disassembly and assembly device, such as Figure 1 、 Figure 2 and Figure 3 As shown, it includes a workbench 1 and a two-axis picking mechanism 2 installed on the workbench 1, a material receiving box 3, a dosage tablet feeding port 4, a detection machine loading tray 5, a dosage tablet picking and placing rack 6, a workpiece disassembly and assembly mechanism 9 and a pushing mechanism 30. The two-axis picking mechanism 2 can move between the dosage tablet feeding port 4, the detection machine loading tray 5 and the dosage tablet picking and placing rack 6. The dosage tablet picking and placing rack 6 is equipped with a clip-type material bin 7. The workbench 1 is provided with a drop port 8 located on the right side of the dosage tablet picking and placing rack 6 and on the upper side of the material receiving box 3;

[0026] like Figure 3 and Figure 4 As shown, the workpiece disassembly and assembly mechanism 9 includes a first linear guide rail 10 installed in the workbench 1, and a disassembly and assembly pusher rod 11 is installed on the first linear guide rail 10. The top end of the disassembly and assembly pusher rod 11 extends from the front side of the dosage piece taking and placing rack 6 to the dosage piece taking and placing rack 6.

[0027] like Figure 4 and Figure 6 As shown, a storage slot 12, a pull-out slot 13 and a discharge port 14 are provided in the dosage tablet taking and placing rack 6. The rear portion of the storage slot 12 is located directly below the clip-type hopper 7. The pull-out slot 13 and the discharge port 14 are respectively connected to the left and right ends of the front portion of the storage slot 12. The discharge port 14 is located on the upper side of the blanking port 8. The top of the disassembly and assembly push rod 11 can move between the storage slot 12, the pull-out slot 13 and the discharge port 14.

[0028] like Figure 6 As shown, the dosimeter workpiece 15 includes a pull-out material clamp 16 and a loading sheet 17 located in the pull-out material clamp 16. A pull-out opening 18 for the loading sheet 17 to pass through is provided at the left end of the pull-out material clamp 16, and a loading slot 19 for placing the dose sheet is provided on the loading sheet 17.

[0029] like Figure 6 As shown, a card slot 20 with an opening toward the front is provided at the left end of the loading piece 17. When the loading piece 17 is received into the pull-out material clamp 16, the card slot 20 is located at the pull-out opening 18. A groove 21 and a ejector pin 22 located in the groove 21 and adapted to the card slot 20 are provided at the top of the disassembly and assembly push rod 11.

[0030] like Figure 3 As shown, an end cover 23 is installed on the upper end of the dosage tablet taking and placing frame 6. The end cover 23 is provided with a taking and placing opening 24 located on the upper side of the drawing groove 13 and for the dosage tablet to pass through.

[0031] like Figure 5 and Figure 6 As shown, the pushing mechanism 30 includes a pushing cylinder 25 mounted on the workbench 1 and located behind the dosage tablet pick-up and placement rack 6. A pushing plate 26 capable of moving within the storage tank 12 is mounted at the front end of the pushing cylinder 25. A baffle 27 is provided at the right side of the front end of the pushing plate 26. When the pushing plate 26 moves to the rear of the storage tank 12, the baffle 27 is blocked between the storage tank 12 and the discharge port 14.

[0032] The baffle 27 can prevent the dosimeter workpiece 15 from accidentally falling out of the discharge port 14 when pushing the dosimeter workpiece 15 from the rear of the storage slot 12 to the front of the storage slot 12, and can also assist in the disassembly and assembly of the push rod 11 to push the loading plate 17 back into the pull-out material clamp 16.

[0033] like Figure 1 and Figure 3 As shown, the two-axis picking mechanism 2 includes two second linear guide rails 28 mounted on the workbench 1 and stacked on each other, and a vacuum pickup 29 for sucking dosage tablets is mounted on the upper second linear guide rail 28 .

[0034] Working principle:

[0035] When the dosimeter workpiece 15 is pushed to the front of the storage slot 12, the loading piece 17 approaches the disassembly and assembly push rod 11 in the initial position, and the ejector pin 22 is naturally stuck in the card slot 20. Since the inner wall of the storage slot 12 restricts the pull-out material clamp 16 from moving to the left, the leftward movement of the disassembly and assembly push rod 11 can pull the loading piece 17 out of the pull-out material clamp 16. The loading slot 19 on the pull-out material clamp 16 pulled into the pull-out slot 13 corresponds to the pick-up and release port 24 up and down, and the dosage piece in the loading slot 19 can be operated by the two-axis picking mechanism 2. The rightward movement of the disassembly and assembly push rod 11 can not only push the loading piece 17 back into the pull-out material clamp 16, but also push the pull-out material clamp 16 out of the discharge port 14 and leave the dosage piece pick-up and release rack 6. The detached pull-out material clamp 16 will fall into the material receiving box 3 through the blanking port 8.

[0036] Automatic disassembly process:

[0037] The dose meter workpiece 15 that needs to be removed is manually placed into the clip-type hopper 7, and the equipment is started to perform the removal operation. The push cylinder 25 controls the push plate 26 to push the dosimeter workpiece 15 at the bottom of the clip-type hopper 7 to the front of the storage slot 12. The disassembly and assembly push rod 11 is controlled to move left to extract the loading piece 17, exposing the dose piece in the loading slot 19. The second linear guide 28 runs to move the vacuum suction end picker 29 to above the pick-up and release port 24. The vacuum suction end picker 29 absorbs the dose piece, and then moves the vacuum suction end picker 29 to above the detection machine loading tray 5 and puts down the dose piece. The disassembly and assembly push rod 11 moves to the right to push the loading piece 17 back into the pull-out material clamp 16. After controlling the push plate 26 to reset and open the discharge port 14, the dosimeter workpiece 15 is pushed into the receiving box 3 from the right side of the disassembly and assembly push rod 11.

[0038] Automatic loading process:

[0039] Manually place the empty dose meter workpiece 15 that needs to be loaded into the clip-type hopper 7, start the equipment to carry out the loading operation, and the push cylinder 25 controls the push plate 26 to push the dose meter workpiece 15 at the bottom of the clip-type hopper 7 to the front of the storage slot 12. The disassembly and assembly push rod 11 is controlled to move to the left to extract the loading piece 17, exposing the empty loading slot 19. The second linear guide 28 runs to move the vacuum suction end picker 29 to the dose sheet feeding port 4 and suck the dose sheet. Then the vacuum suction end picker 29 is controlled to move to the pick-up and release port 24 and put the dose sheet down. The dose sheet falls into the loading slot 19. The disassembly and assembly push rod 11 moves to the right to push the loading sheet 17 back into the pull-out material clamp 16. After controlling the push plate 26 to reset and open the discharge port 14, the dosimeter workpiece 15 is pushed into the receiving box 3 from the right side of the disassembly and assembly push rod 11.

[0040] The above are only preferred embodiments of the present invention and do not limit the present invention in any form. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present invention fall within the scope of protection of the present invention.
