[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] This utility model discloses a rapid assembly device for sampling tubes, such as... Figures 1-5As shown, the device includes a base 1. An assembly frame 2 for assembling sampling tubes and tube caps is fixedly installed on the right side of the top surface of the base 1, and a feeding frame 4 is fixedly installed on the left side of the top surface of the base 1. A first drive roller 3 is rotatably connected to the lower side of the inside of the assembly frame 2, and multiple feeding racks 5 are fixedly installed on the outer surface of the first drive roller 3. The first drive roller 3 can rotate inside the assembly frame 2, thereby driving the multiple feeding racks 5 to rotate.

[0025] The upper inner side of the assembly frame 2 is rotatably connected to the second drive roller 6, and the outer surface of the second drive roller 6 is provided with multiple cap-mounting components. The multiple cap-mounting components correspond one-to-one with multiple loading racks 5. When the second drive roller 6 rotates, it will drive the multiple cap-mounting components to rotate.

[0026] The outer surface of the loading rack 5 is provided with guide holes 503 on both sides, and two fixed plates 501 are slidably connected inside the two guide holes 503. The two fixed plates 501 can move along the two guide holes 503.

[0027] Five fixing slots 502 are provided on each of the two fixing plates 501 on opposite sides. The cross-sectional shape of the fixing slots 502 is arc-shaped so as to better fit the cylindrical test tube. Through the five fixing slots 502, when the two fixing plates 501 are close to each other, five test tubes to be assembled can be clamped and fixed at the same time.

[0028] A bidirectional threaded rod 504 is rotatably connected to one side of the outer surface of the loading trough, and one side of each of the two fixing plates 501 is threadedly connected to the bidirectional threaded rod 504. The outer surface of the bidirectional threaded rod 504 is provided with two opposite threads. When the bidirectional threaded rod 504 rotates, the two fixing plates 501 can move in opposite directions to clamp and fix test tubes of different diameters. A first micro motor 505 is fixedly installed on the outer surface of the loading rack 5 on one side of the bidirectional threaded rod 504, and the output end of the first micro motor 505 is fixedly connected to the bidirectional threaded rod 504. The first micro motor 505 can drive the bidirectional threaded rod 504 to rotate.

[0029] The capping assembly includes a first electric push rod 602 fixedly installed on the outer surface of the second drive roller 6, and a fixing box 603 fixedly installed at the output end of the first electric push rod 602. Two telescopic rods 601 are fixedly installed on the outer surface of the second drive roller 6 on one side of the first electric push rod 602, and both telescopic rods 601 are fixedly connected to the fixing box 603. When the first electric push rod 602 pushes the fixing box 603 to move, the two telescopic rods 601 will extend or retract.

[0030] The fixed box 603 has five rotating shafts 604 rotatably connected inside, and two sprockets 605 are fixedly installed on the outer surface of each of the five rotating shafts 604 on one side inside the fixed box 603. Multiple chains 606 are sleeved on the outer surface of the ten sprockets 605. When one of the rotating shafts 604 rotates, it will drive the other four rotating shafts 604 to rotate through the multiple chains 606.

[0031] Five pneumatic grippers 607 are rotatably connected to one side of the outer surface of the fixed box 603. The pneumatic grippers 607 are actuators that use compressed air as power to clamp or grasp workpieces. Since the pneumatic grippers 607 are existing technology, they will not be described in detail here.

[0032] Five pneumatic grippers 607 can hold five caps to be assembled at once, and five rotating shafts 604 are fixedly connected to the five pneumatic grippers 607 respectively. When the five rotating shafts 604 rotate, they will drive the five pneumatic grippers 607 to rotate.

[0033] A second micro motor 608 is fixedly installed on one side of the outer surface of the fixed box 603, and the second micro motor 608 is fixedly connected to one of the rotating shafts 604. When the second micro motor 608 drives one of the rotating shafts 604 to rotate, it will drive the other four rotating shafts 604 to rotate, thereby causing the five pneumatic grippers 607 to rotate.

[0034] Two first pulleys 201 are rotatably connected to one side of the outer surface of the assembly frame 2, and the two first pulleys 201 are fixedly connected to the first drive roller 3 and the second drive roller 6 respectively. When the two first pulleys 201 rotate, they will drive the first drive roller 3 and the second drive roller 6 to rotate.

[0035] The outer surface of the assembly frame 2 is rotatably connected to two second pulleys 203 on one side of the first pulley 201. Two belts 202 are respectively fitted between the two first pulleys 201 and the two second pulleys 203. When the first pulley 201 rotates, it will drive the second pulley 203 to rotate through the belts 202.

[0036] Each of the two second pulleys 203 has a drive gear 204 fixedly mounted on one end, and the two drive gears 204 mesh. When one drive gear 204 rotates, it will push the other drive gear 204 to rotate in the opposite direction, which will cause the two second pulleys 203 to rotate in the opposite direction.

[0037] A sector gear 206 is rotatably connected to one side of the drive gear 204 on the outer surface of the assembly frame 2, and the sector gear 206 meshes with one of the drive gears 204. A drive motor 205 is fixedly installed on one side of the assembly frame 2, and the output end of the drive motor 205 is fixedly connected to the sector gear 206. The drive motor 205 drives the sector gear 206 to rotate, and the rotating sector gear 206 will drive one of the drive gears 204 to rotate intermittently, which will cause the two drive gears 204 to rotate intermittently in opposite directions, which will cause the first drive roller 3 and the second drive roller 6 to rotate intermittently in opposite directions.

[0038] The user places the tube caps to be assembled between the clamping parts of the five pneumatic grippers 607 in sequence, so that the five pneumatic grippers 607 clamp and fix the five tube caps. The first micro motor 505 drives the bidirectional threaded rod 504 to rotate, so that the two fixing plates 501 move closer to each other, thereby clamping and fixing the test tube inserted between the two fixing plates 501. Then, as the first drive roller 3 and the second drive roller 6 rotate intermittently in opposite directions, the clamped test tube and the clamped tube cap will be driven to rotate intermittently in opposite directions.

[0039] When the clamped cap rotates to the top of the clamped test tube, the first electric actuator 602 pushes the fixing box 603 to move towards one side of the clamped test tube. At the same time, the second micro motor 608 drives one of the rotating shafts 604 to rotate, causing the five pneumatic grippers 607 to rotate the cap, thereby screwing the five caps onto one end of the five test tubes to complete the assembly of the test tubes and caps.

[0040] A discharge port 207 is provided on the right side of the top surface of the base 1, and the discharge port 207 is located below the assembly frame 2. After the test tube and the cap are assembled, as the first drive roller 3 and the second drive roller 6 continue to rotate, when the assembled test tube rotates to above the discharge port 207, the first micro motor 505 drives the bidirectional threaded rod 504 to rotate, so that the two fixing plates 501 move away from each other, and then the assembled test tube will fall through the discharge port 207 into the container placed below the discharge port 207, so as to collect the assembled test tube.

[0041] It should be noted that each rotation of the first drive roller 3 and the second drive roller 6 will cause one of the loading racks 5 and one of the fixed boxes 603 to rotate to the opposite position.

[0042] The feeding rack 4 has five storage slots 401 inside, and each of the five storage slots 401 has a guide slot 406 inside. Each of the five storage slots 401 is slidably connected to a movable rod 402. A part of the movable rod 402 is located inside the storage slot 401, and the other part of the movable rod 402 is located on the outer surface of the storage slot 401. The movable rod 402 can move inside the storage slot 401.

[0043] The five movable rods 402 are located at one end outside the storage tank 401 and are fixedly installed with a connecting plate 403. When the connecting plate 403 moves, it will drive the five movable rods 402 to move.

[0044] A second electric push rod 404 is fixedly installed on the outer surface of the feeding rack 4 near the connecting plate 403, and the output end of the second electric push rod 404 is fixedly connected to the connecting plate 403. When the second electric push rod 404 pushes the connecting plate 403 to move, it will drive the five movable rods 402 to move simultaneously.

[0045] Each of the five movable rods 402 has a push plate 405 fixedly installed at one end inside the storage tank 401. The test tubes to be assembled are placed horizontally in the storage tank 401 and stacked on top of each other. The first electric push rod 602 pushes the connecting plate 403 to move, which in turn causes the five movable rods 402 to push the five push plates 405 to move. The five push plates 405 then push the five test tubes to move, so that the five test tubes are inserted between the two fixed plates 501 through the five guide grooves 406 for assembly. The positions of the five guide grooves 406 correspond one-to-one with the positions of the five fixed grooves 502, so that the test tubes entering the guide grooves 406 can be accurately moved into the fixed grooves 502. Each rotation of the first drive roller 3 will cause one of the loading racks 5 to rotate to the same horizontal line as the guide groove 406.

[0046] The working principle of this utility model is as follows: After the user sets the control program, the test tubes to be assembled are placed horizontally in the storage tank 401 and stacked one after another until the five storage tanks 401 are filled with test tubes to be assembled. Then the user places the tube caps to be assembled between the clamping parts of the pneumatic gripper 607, so that the pneumatic gripper 607 clamps and fixes the tube caps.

[0047] The drive motor 205 drives the sector gear 206 to rotate. The rotating sector gear 206 drives one of the drive gears 204 to rotate intermittently, which in turn causes the two drive gears 204 to rotate intermittently in opposite directions. This causes the first drive roller 3 and the second drive roller 6 to rotate intermittently in opposite directions. When the loading rack 5 rotates to the opening of the guide groove 406, the first electric push rod 602 pushes the connecting plate 403 to move. This causes the five movable rods 402 to push the five push plates 405 to move. The five push plates 405 then push the five test tubes to move, so that the five test tubes are inserted between the two fixed plates 501 through the five guide grooves 406. The first micro motor 505 drives the bidirectional threaded rod 504 to rotate, so that the two fixed plates 501 move closer to each other to clamp and fix the five test tubes.

[0048] Then, as the first drive roller 3 and the second drive roller 6 continue to rotate, the clamped cap will rotate to the top of the clamped test tube. At this time, the first electric push rod 602 pushes the fixing box 603 to move to one side of the clamped test tube. The second micro motor 608 drives one of the rotating shafts 604 to rotate, causing the five pneumatic grippers 607 to rotate the cap, thereby screwing the five caps onto one end of the five test tubes to complete the assembly of the test tubes and caps. As the first drive roller 3 and the second drive roller 6 continue to rotate, the above steps will be repeated to continuously assemble the test tubes and caps.

[0049] During the entire assembly process, when the assembled test tube rotates to above the discharge port 207, the first micro motor 505 drives the bidirectional threaded rod 504 to rotate, causing the two fixing plates 501 to move away from each other. This causes the assembled test tube to fall through the discharge port 207 into the container placed below the discharge port 207 for collection. During the entire assembly process, the user only needs to set the control program before assembly, replenish the test tubes in the feeding rack 4, and periodically place the tube caps inside the pneumatic gripper 607.

[0050] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
