Description

Technical Field

[0001] This disclosure relates to the field of capping devices, and in particular to a bead filling and capping machine. Background Technology

[0002] Biochemical reagents are an indispensable part of life science research. They are biological materials or organic compounds used in life science research, as well as reagents used in clinical diagnosis and medical research. Due to the breadth and rapid development of the life science field, biochemical reagents are diverse and complex in nature.

[0003] For biological reagents requiring the filling of test solutions and grinding beads, the production process first involves filling test tubes with grinding beads, then injecting the test solution into the tubes, and finally tightening the caps onto the test tube openings using a capping machine. Traditionally, this involves manually counting the exact number of grinding beads to be filled into the test tubes, injecting the test solution into the test tubes using a handheld dispensing gun, and then capping the test tubes. The test tubes and caps are then transported to the capping machine via a conveyor belt for tightening. However, since both the grinding bead loading and dispensing processes are manual, there are issues with efficiency. Furthermore, errors during manual operation lead to a decrease in product yield. Additionally, during transport, caps may fall off or be capped at an angle, further reducing the capping yield.

[0004] Therefore, there is an urgent need for a device with a high degree of automation and a high yield rate of capping. Summary of the Invention

The bead filling mechanism loads the grinding beads into the test tubes, the liquid injection mechanism injects the test liquid into the test tubes, and finally the test tubes and bottle caps are tightened by the capping mechanism. All these processes are mechanized, reducing the number of manual operation steps and avoiding deviations caused by manual operation, thus improving production efficiency and product yield.

[0024] 2. In the above-mentioned bead filling and capping machine, when the test tube rotates to the capping mechanism, the clamping component first clamps the test tube in the embedded groove, the capping component clamps the bottle cap from the feeding conveyor component and moves it to the mouth of the test tube, and then the capping component screws the bottle cap and the test tube so that the bottle cap and the test tube are screwed and fixed. That is, the bottle cap is only clamped to the mouth of the test tube when it is screwed, which avoids the problem of the bottle cap falling off or being crooked when the bottle cap and the test tube are transported together, thereby improving the capping yield.

[0037] This disclosure provides a bead filling and capping machine 10, including a worktable 100, a rotating mechanism 200, a bead filling mechanism 300, a liquid injection mechanism 400, and a capping mechanism 500. The rotating mechanism 200 includes a turntable 210 and a rotating drive component 220. The rotating drive component 220 is mounted on the worktable 100, and the turntable 210 is connected to the power output end of the rotating drive component 220. The turntable 210 has an embedding groove 211 for embedding test tubes. The bead filling mechanism 300 is mounted on the worktable 100 and is used to fill grinding beads into the test tubes. The liquid injection mechanism 400 is mounted on the worktable 100 and is used to inject the test tubes into the liquid injection mechanism 500. Liquid is injected into the test tube; the capping mechanism 500 is installed on the workbench 100, and the bead loading mechanism 300, the liquid injection mechanism 400 and the capping mechanism 500 are arranged sequentially at intervals along the circumference of the turntable 210. The capping mechanism 500 includes a feeding conveying component 510, a pressing component 520 and a capping component 530. The feeding conveying component 510 is arranged adjacent to the workbench 100 and is used to convey bottle caps. The pressing component 520 is installed on the workbench 100 and is used to press the test tube in the embedded groove 211. The capping component 530 is used to clamp and move the bottle cap to the test tube and screw the bottle cap onto the test tube.

[0038] The aforementioned bead-filling and capping machine 10 uses a rotating drive 220 to drive a turntable 210 to rotate, causing test tubes in the embedding groove 211 to sequentially pass through a bead-filling mechanism 300, a liquid injection mechanism 400, and a capping mechanism 500. The bead-filling mechanism 300 loads grinding beads into the test tubes, the liquid injection mechanism 400 injects the test liquid into the test tubes, and finally, the test tubes are tightened to the caps via the capping mechanism 500. Multiple processes are mechanized, reducing manual operation steps and avoiding deviations caused by manual operation. This improves production efficiency and product yield. When the test tube rotates to the capping mechanism 500, the clamping component 520 first clamps the test tube in the embedding groove 211, and the capping component 530 clamps the bottle cap of the feeding conveying component 510 and moves it to the mouth of the test tube. Then, the capping component 530 screws the bottle cap and the test tube, so that the bottle cap and the test tube are screwed and fixed. That is, the bottle cap is only clamped to the mouth of the test tube when it is screwed, which avoids the problem of the bottle cap falling off or being crooked when the bottle cap and the test tube are transported together, thereby improving the capping yield.

[0039] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0040] like Figure 1 and Figure 2As shown, an embodiment of a bead filling and capping machine 10 includes a worktable 100, a rotating mechanism 200, a bead filling mechanism 300, a liquid injection mechanism 400, and a capping mechanism 500. The rotating mechanism 200 includes a turntable 210 and a rotating drive component 220. The rotating drive component 220 is mounted on the worktable 100. The turntable 210 is connected to the power output end of the rotating drive component 220. The turntable 210 has an embedding groove 211 for embedding test tubes. The bead filling mechanism 300 is mounted on the worktable 100 and is used to fill grinding beads into the test tubes. The liquid injection mechanism 400 is mounted on the worktable 100 and is used to inject test liquid into the test tubes.

[0041] Furthermore, the capping mechanism 500 is mounted on the workbench 100, and the bead loading mechanism 300, the liquid injection mechanism 400, and the capping mechanism 500 are arranged sequentially at intervals along the circumference of the turntable 210. Please refer to the following: Figure 2 and Figure 3 The capping mechanism 500 includes a feeding and conveying assembly 510, a pressing assembly 520, and a capping assembly 530. The feeding and conveying assembly 510 is arranged adjacent to the workbench 100 and is used to convey bottle caps. The pressing assembly 520 is installed on the workbench 100 and is used to press the test tube in the embedded groove 211. The capping assembly 530 is used to clamp and move the bottle cap to the test tube and screw the bottle cap onto the test tube.

[0042] In this embodiment, the bead filling mechanism 300, the liquid injection mechanism 400, and the capping mechanism 500 are arranged around the turntable 210 so that the test tubes pass through the bead filling mechanism 300, the liquid injection mechanism 400, and the capping mechanism 500 in sequence. The working process of the bead filling and capping machine 10 is as follows: First, the test tube is placed and fixed in the embedding groove 211. The rotating drive component 220 drives the turntable 210 to rotate to the bead filling mechanism 300, which loads a preset number of grinding beads into the test tube. Then, the rotating drive component 220 drives the turntable 210 to rotate to the liquid injection mechanism 400, which injects the test liquid into the test tube. Finally, the rotating drive component 220 drives the turntable 210 to rotate to the capping mechanism 500. At this time, the pressing component 520 moves to press the test tube into the embedding groove 211 to prevent the test tube from rotating when it is screwed. At the same time, the feeding and conveying component 510 conveys the cap to the predetermined position. The capping component 530 moves to clamp the cap and move it to the mouth of the test tube. The capping component 530 drives the cap to rotate so that the cap is screwed onto the test tube, thereby completing the capping operation. In this embodiment, the rotating drive component 220 is a motor or a cylinder.

[0043] The aforementioned bead-filling and capping machine 10 uses a rotating drive 220 to drive a turntable 210 to rotate, causing test tubes in the embedding groove 211 to sequentially pass through a bead-filling mechanism 300, a liquid injection mechanism 400, and a capping mechanism 500. The bead-filling mechanism 300 loads grinding beads into the test tubes, the liquid injection mechanism 400 injects the test liquid into the test tubes, and finally, the test tubes are tightened to the caps via the capping mechanism 500. Multiple processes are mechanized, reducing manual operation steps and avoiding deviations caused by manual operation. This improves production efficiency and product yield. When the test tube rotates to the capping mechanism 500, the clamping component 520 first clamps the test tube in the embedding groove 211, and the capping component 530 clamps the bottle cap of the feeding conveying component 510 and moves it to the mouth of the test tube. Then, the capping component 530 screws the bottle cap and the test tube, so that the bottle cap and the test tube are screwed and fixed. That is, the bottle cap is only clamped to the mouth of the test tube when it is screwed, which avoids the problem of the bottle cap falling off or being crooked when the bottle cap and the test tube are transported together, thereby improving the capping yield.

[0044] like Figure 3 As shown, in one embodiment, the screw cap assembly 530 includes a first fixed frame 531, a first vertical drive member 532, a first horizontal drive member 533, a rotary drive member 534, a movable frame 535, and two clamping plates 536. The first fixed frame 531 is mounted on the workbench 100. The first vertical drive member 532 is connected to the first fixed frame 531. The movable frame 535 is fixedly connected to the power output end of the first vertical drive member 532. The rotary drive member 534 is mounted on the movable frame 535. The power output end of the rotary drive member 534 is connected to the first horizontal drive member 533. The power output end of the first horizontal drive member 533 is connected to the two clamping plates 536 respectively, so that the two clamping plates 536 move closer to or further away from each other. In this embodiment, the first vertical drive member 532 is mounted on the first fixed frame 531. The first vertical drive member 532 drives the moving frame 535 to move, thereby causing the two clamping plates 536 to move up and down in the vertical plane. The rotation drive member 534 drives the first horizontal drive member 533 to rotate, thereby causing the two clamping plates 536 to rotate. The first horizontal drive member 533 causes the two clamping plates 536 to move closer or further away from each other, so that the two clamping plates 536 clamp or loosen the bottle cap. The movement process of the capping assembly 530 is as follows: when the bottle cap is conveyed to the predetermined position by the feeding conveying assembly 510, the first vertical drive member 532 drives the two clamping plates 536 to move downward to approach the test tube, and the first horizontal drive member 533 drives the two to move closer to each other to clamp the bottle cap. Then the first vertical drive member 532 continues to move downward to place the bottle cap on the mouth of the test tube. At this time, the rotation drive member 534 drives the two clamping plates 536 to rotate, thereby causing the bottle cap to be screwed onto the test tube. Furthermore, the first horizontal drive member 533, the rotary drive member 534, and the first vertical drive member 532 are motors.

[0045] like Figure 3 As shown, in one embodiment, the first fixed frame 531 is provided with a slide rail 531a, and the movable frame 535 is slidably disposed on the slide rail 531a, so that the first vertical drive member 532 drives the movable frame 535 to move along the extension direction of the slide rail 531a. In this embodiment, the first fixed frame 531 is provided with a slide rail 531a, and the movable frame 535 is slidably disposed on the slide rail 531a to further fix the movable frame 535. The output end of the first vertical drive member 532 drives the movable frame 535 to move up and down along the slide rail 531a, thereby driving the two clamping plates 536 to move up and down.

[0046] like Figure 3 As shown, in one embodiment, the clamping assembly 520 includes a second horizontal drive member 521, a pressure block 522, and a mounting bracket 523. The mounting bracket 523 is mounted on the workbench 100. The second horizontal drive member 521 is connected to the mounting bracket 523, and the power output end of the second horizontal drive member 521 is connected to the pressure block 522. The pressure block 522 is positioned opposite to the embedding groove 211, so that the second horizontal drive member 521 drives the pressure block 522 to press against the test tube. In this embodiment, the second horizontal drive member 521 is mounted on the mounting bracket 523. The second horizontal drive member 521 drives the pressure block 522 to move horizontally. When the turntable 210 rotates to a preset position, the pressure block 522 is positioned opposite to the embedding groove 211. At this time, the second horizontal drive member 521 drives the pressure block 522 to move closer to the embedding groove 211, so that the pressure block 522 presses the test tube into the embedding groove 211. Furthermore, the second horizontal drive component 521 is a motor or a cylinder.

[0047] like Figure 2 and Figure 4As shown, in one embodiment, the feeding and conveying assembly 510 includes a first vibrating feeding plate 511, a support frame 512, a conveying frame 513, a third horizontal drive member 514, and a first baffle 515. The first vibrating feeding plate 511 is disposed adjacent to the worktable 100. The support frame 512 is connected to the mounting frame 523. The third horizontal drive member 514 is mounted on the support frame 512. The first baffle 515 is fixedly connected to the power output end of the third horizontal drive member 514. The first baffle 515 is slidably disposed with respect to the support frame 512. The first baffle 515 has a receiving groove 515a. The conveying channel of the conveying frame 513 is connected to the first vibrating feeding plate 511 and the receiving groove 515a respectively. The third horizontal drive member 514 drives the first baffle 515 to move so that the first baffle 515 moves closer to or away from the conveying frame 513. In this embodiment, the first vibrating feeding plate 511 transports the test tube to the conveyor frame 513 and brings the test tube into the receiving groove 515a of the first baffle 515. At this time, the third horizontal drive member 514 drives the first baffle 515 to move below the first vertical drive member 532. The first vertical drive member 532 drives the two clamping plates 536 to move downward. The first horizontal drive member 533 drives the two clamping plates 536 to move closer to each other to clamp the test tube. Then, the third horizontal drive member 514 continues to drive the first baffle 515 to move away from the conveyor frame 513, so that a gap is formed between the first baffle 515 and the conveyor frame 513 to avoid the first baffle 515 interfering with the downward movement of the clamping plates 536. That is, the first vertical drive member 532 continues to drive the two clamping plates 536 through the gap between the first baffle 515 and the conveyor frame 513, thereby causing the bottle cap to be placed on the mouth of the test tube. Further, the third horizontal drive member 514 is a motor or a cylinder.

[0048] like Figure 4As shown, in one embodiment, the feeding and conveying assembly 510 further includes a second vertical drive member 516, a fourth horizontal drive member 517, a moving plate 518, and a first sensor 519. The second vertical drive member 516 is mounted on the mounting frame 523, and the fourth horizontal drive member 517 is mounted on the support frame 512. The conveying frame 513 includes a first conveying frame body 513a and a second conveying frame body 513b. The conveying channel of the first conveying frame body 513a communicates with the first vibrating feeding plate 511, and the conveying channel of the second conveying frame body 513b communicates with the receiving groove 515a. There is a gap between the first conveyor frame body 513a and the second conveyor frame body 513b. The moving plate 518 is located between the first conveyor frame body 513a and the second conveyor frame body 513b. The moving plate 518 has a groove. The moving plate 518 is fixedly connected to the power output end of the second vertical drive member 516. The first sensor 519 is installed on the support frame 512. The first sensor 519 is used to sense the bottle cap in the groove so that the output end of the fourth horizontal drive member 517 pushes the bottle cap in the groove into the second conveyor frame body 513b. In this embodiment, the first vibrating feeding plate 511 transports the bottle caps to the first conveyor frame body 513a. Since there is a gap between the first conveyor frame body 513a and the second conveyor frame body 513b, and the moving plate 518 is located in the gap, the bottle caps on the first conveyor frame body 513a eventually fall onto the moving plate 518 under the pushing force. The second vertical drive member 516 drives the moving plate 518 to move in the vertical direction so that the moving plate 518 is positioned opposite to the second conveyor frame body 513b. At this time, the first sensor 519 senses the bottle cap in the groove and releases a signal to make the fourth horizontal drive member 517 move so that the output end of the fourth horizontal drive member 517 pushes the bottle cap into the second conveyor frame body 513b. The fourth horizontal drive member 517 continues to move so that the bottle cap passes through the second conveyor frame body 513b and finally enters the receiving groove 515a of the first baffle 515. This makes the bottle cap clamping operation more accurate. Furthermore, the second vertical drive component 516 and the fourth horizontal drive component 517 are motors or cylinders.

[0049] In one embodiment, the first conveyor frame body 513a and the second conveyor frame body 513b are vertically offset. In this embodiment, the second conveyor frame body 513b is higher than the first conveyor frame body 513a. Bottle caps are transferred into the groove of the moving plate 518 via the first conveyor frame body 513a. The second vertical drive member 516 drives the moving plate 518 to rise, so that the groove is positioned opposite to the second conveyor frame body 513b. The output end of the fourth horizontal drive member 517 moves to push the bottle caps in the groove into the second conveyor frame body 513b.

[0050] like Figure 4 As shown, in one embodiment, the feeding and conveying assembly 510 further includes a slide plate 510a and a push rod 510b. The support frame 512 is provided with a guide rail 512a. The slide plate 510a and the first baffle 515 are both slidably disposed on the guide rail 512a. The slide plate 510a is fixedly connected to the output end of the fourth horizontal drive member 517. The push rod 510b is fixedly connected to the slide plate 510a and is correspondingly disposed with the groove. In this embodiment, the slide plate 510a is slidably disposed on the guide rail 512a. The fourth horizontal drive member 517 drives the slide plate 510a to move along the guide rail 512a, thereby driving the push rod 510b to move. This causes the push rod 510b to push the bottle cap in the groove into the second conveyor frame body 513b. When the push rod 510b continues to move, it pushes the bottle cap in the second conveyor frame body 513b into the receiving groove 515a of the first baffle 515. Furthermore, the first baffle 515 is slidably disposed on the guide rail 512a. The third horizontal drive member 514 drives the first baffle 515 to move horizontally along the extension direction of the guide rail 512a. When the bottle cap enters the receiving groove 515a of the first baffle 515, the two clamping plates 536 move to clamp the bottle cap in the receiving groove 515a. At this time, the third horizontal drive member 514 drives the first baffle 515 to continue to move in a direction away from the body of the second conveyor frame 513b, so that there is a gap between the first baffle 515 and the body of the second conveyor frame 513b. The two clamping plates 536 pass through the gap to cover the bottle cap on the test tube opening below.

[0051] like Figure 1 and Figure 5As shown, in one embodiment, the bead loading mechanism 300 includes a second fixed frame 310, a second vibrating feeding plate 320, a feeding pipe 330, a transmission plate 340, a second baffle 350, and a fifth horizontal drive member 360. The second fixed frame 310 and the second vibrating feeding plate 320 are both mounted on the worktable 100. The feeding pipe 330 is mounted on the second fixed frame 310. The fifth horizontal drive member 360 is fixedly connected to the second fixed frame 310. The transmission plate 340... The transmission plate 340 is connected to the power output end of the fifth horizontal drive member 360. A material passage 341 is opened inside the transmission plate 340. The feeding pipe 330 is connected to the material passage 341 and the second vibrating feeding plate 320 respectively. The second baffle 350 is fixedly connected to the second fixed frame 310. The second baffle 350 is provided with a clearance hole (not shown). The fifth horizontal drive member 360 is used to drive the transmission plate 340 to move so that the material passage 341 communicates with the clearance hole. In this embodiment, the second vibrating feeder 320 transports the grinding beads into the feed tube 330, and then into the feed channel 341 of the transmission plate 340. At this time, the grinding beads in the feed channel 341 are blocked by the second baffle 350. When the number of grinding beads in the feed channel 341 reaches a preset value, the fifth horizontal drive 360 ​​drives the transmission plate 340 to move horizontally so that the feed channel 341 communicates with the clearance hole. At this time, the grinding beads in the feed channel 341 fall into the test tube below through the clearance hole. Further, the fifth horizontal drive 360 ​​is a motor or a cylinder.

[0052] Furthermore, in order to improve the accuracy of measuring the number of grinding beads in the feed channel 341, such as... Figure 5 As shown, in one embodiment, the bead loading mechanism 300 further includes a second sensor 370, which is mounted on the second fixed frame 310. The transmission plate 340 has a through hole that communicates with the material passage 341. The second sensor 370 is used to sense the grinding beads in the material passage 341. In this embodiment, the second sensor 370 is mounted on the second fixed frame 310, and the through hole is located on one side of the end of the transmission plate 340. When the number of grinding beads in the material passage 341 reaches a preset value, the second sensor 370 senses this through the through hole and releases a signal to cause the fifth horizontal drive member 360 to drive the transmission plate 340 to move horizontally, so that the material passage 341 communicates with the clearance hole, thereby loading the accurately numbered grinding beads into the test tube below.

[0053] like Figure 6As shown, in one embodiment, the injection mechanism 400 includes a third fixing frame 410, an injection pipe 420, a pump (not shown), and a storage tank (not shown). The third fixing frame 410 is mounted on the workbench 100, and the injection pipe 420 is mounted on the third fixing frame 410. The injection pipe 420 is connected to the storage tank, and the pump is used to pressurize the test liquid in the storage tank into the injection pipe 420. In this embodiment, the pump pressurizes the test liquid in the storage tank into the injection pipe 420, and then the test liquid flows into the test tube through the injection pipe 420.

[0054] It is understandable that, in order to improve the convenience of feeding 10 pairs of test tubes into the bead filling and capping machine, such as... Figure 7 As shown, in one embodiment, the bead filling and capping machine 10 further includes a test tube feeding mechanism 600. The test tube feeding mechanism 600 includes a third vibrating feeding plate 610, a fourth fixing frame 620, and a third sensor 630. The third vibrating feeding plate 610 is disposed adjacent to the worktable 100, and the outlet of the third vibrating feeding plate 610 is connected to the embedding groove 211. The fourth fixing frame 620 is installed on the worktable 100 and disposed adjacent to the third vibrating feeding plate 610. The third sensor 630 is installed on the fourth fixing frame 620 and is used to detect the test tubes in the embedding groove 211. In this embodiment, the test tube feeding mechanism 600 is located adjacent to the bead filling mechanism 300, that is, the test tube feeding mechanism 600 is located on the side of the bead filling mechanism 300 away from the liquid injection mechanism 400, which is the first station. The third vibrating feeding plate 610 includes a feeding plate 611 and a conveying frame 612. The outlet of the feeding plate 611 is connected to the conveying frame 612. The conveying channel of the conveying frame 612 is correspondingly arranged with the embedding groove 211. The feeding plate 611 is used for vibrating feeding, so that the test tubes move along the outlet of the feeding plate 611. The material enters the conveyor frame, and finally the test tube passes through the conveyor frame and enters the embedding slot 211. The sensing end of the third sensor 630 is set in correspondence with the embedding slot 211. The third sensor 630 is used to sense whether there is a test tube in the embedding slot 211. When the test tube reaches the embedding slot 211, the third sensor 630 releases a signal to drive the rotary drive 220 to drive the turntable 210 to rotate. The cooperation of the third vibrating feeding plate 610 and the third sensor 630 makes the test tube feeding convenient and highly automated, thereby improving production efficiency. The working process of the test tube feeding mechanism 600 is as follows: the third vibrating feeding plate 610 is started, and the feeding plate 611 vibrates to feed the test tubes into the conveying channel of the conveying frame 612. Finally, the test tubes in the conveying channel enter the embedding slot 211. The third sensor 630 senses the test tubes in the embedding slot 211 and releases a signal to drive the rotating drive component 220 to drive the turntable 210 to rotate, so that the test tubes in the embedding slot 211 enter the bead loading mechanism 300, thus improving the convenience of test tube feeding.

[0055] Furthermore, after screwing the test tubes and bottle caps on, there may be issues such as them being screwed on crookedly or not tightened properly, leading to subsequent leakage. Therefore, it is necessary to test the test tubes and bottle caps after screwing them on. Figure 1 and Figure 8 As shown, in one embodiment, the bead filling and capping machine 10 further includes a height detection mechanism 700. The height detection mechanism 700 includes a fifth fixed frame 710, a fourth sensor 720, a third vertical drive member 730, and a contact plate 740. The fifth fixed frame 710 is mounted on the worktable, the third vertical drive member 730 is mounted on the fifth fixed frame 710, and the power output end of the third vertical drive member 730 is connected to the contact plate 740. The fourth sensor 720 is mounted on the fifth fixed frame 710 and is used to detect the height to which the contact plate 740 descends. In this embodiment, the fifth fixing frame 710 is arranged adjacent to the capping mechanism 500, that is, the fifth fixing frame 710 is located on the side of the capping mechanism 500 away from the liquid injection mechanism 400, so that after the test tube and bottle cap are screwed by the capping mechanism 500, the turntable 210 rotates to rotate the test tube and bottle cap to the fifth fixing frame 710. The third vertical drive member 730 is installed on the fifth fixing frame 710, and the power output end of the third vertical drive member 730 is fixedly connected to the contact plate 740. The contact plate 740 is correspondingly arranged with the embedded groove 211. The third vertical drive member 730 is used to drive the contact plate 740 to move up and down. The fourth sensor 720 is installed on the fifth fixing frame 710, and the sensing port of the fourth sensor 720 is arranged facing the contact plate 740 to detect the distance the contact plate 740 moves. Based on the distance the contact plate 740 moves, the overall height of the test tube and bottle cap can be deduced, thereby determining whether there are defects in the screwing of the test tube and bottle cap, so as to improve the product yield. Specifically, when the turntable 210 rotates to the height detection mechanism 700, the third vertical drive component 730 drives the contact plate 740 to descend, so that the contact plate 740 abuts against the bottle cap. At the same time, the fourth sensor 720 senses the descending height of the contact plate 740. Understandably, when the bottle cap and test tube are not tightened or are misaligned, the overall height of the bottle cap and test tube is greater than the height of a good product. Thus, the fourth sensor 720 can detect whether the bottle cap is tightened or misaligned. For example, if the normal value is set for the descending height of the contact plate 740 to be 2 cm, when the descending height of the contact plate 740 is less than 2 cm, it indicates that the height of the bottle cap and test tube is too large, meaning the capping is unqualified and needs to be reprocessed.

[0056] Furthermore, after the test tube and capping mechanism 500 are screwed on, there are problems such as misalignment or looseness. In order to facilitate the discharge of defective products, such as... Figure 1 and Figure 8As shown, in one embodiment, the bead filling and capping machine 10 further includes a pipe arrangement mechanism 800. The pipe arrangement mechanism 800 includes a sixth fixed frame 810, a sixth horizontal drive component 820, a push plate 830, and a collection box 840. The sixth fixed frame 810 is installed on the workbench 100. The sixth horizontal drive component 820 is connected to the sixth fixed frame 810. The power output end of the sixth horizontal drive component 820 is fixedly connected to the push plate 830. The push plate 830 is correspondingly arranged with the embedding groove 211. The collection box 840 is installed on the workbench 100 and is located below the embedding groove 211. In this embodiment, the pipe-laying mechanism 800 is located on the side of the height detection mechanism 700 away from the capping mechanism 600. That is, the turntable 210 passes through the capping mechanism 600 and then sequentially passes through the height detection mechanism 700 and the pipe-laying mechanism 800. The sixth horizontal drive member 820 is mounted on the sixth fixed frame 810. The push plate 830 is connected to the output shaft of the sixth horizontal drive member 820. There is a material passage gap between the push plate 830 and the sixth horizontal drive member 820 so that the turntable passes through the material passage gap when it rotates. The sixth horizontal drive member 820 is electrically connected to the fourth sensor 720 of the height detection mechanism 700 so that the sixth horizontal drive member 820 starts working when it receives the signal from the fourth sensor 720. The push plate 830 is located on one side of the embedding groove 211. When the sixth horizontal drive member 820 receives the signal... When a signal is received, it indicates that the test tube in the insert slot 211 is not properly capped. The sixth horizontal drive component 820 drives the push plate 830 to move towards the insert slot 211, so that the push plate 830 abuts against the test tube and pushes the test tube out of the insert slot 211. Finally, the test tube falls into the collection box 840 for further processing. Then, the sixth horizontal drive component 820 drives the push plate 830 to reset, allowing the next test tube to pass. In this way, the height detection mechanism 700 and the tube arrangement mechanism 800 cooperate to discharge products with poor capping, further improving the product yield and facilitating the rework of products with poor capping. At the same time, the height detection mechanism 700 and the tube arrangement mechanism 800 are arranged at intervals along the circumference of the turntable, which helps to improve the compactness and space utilization of the bead filling and capping machine 10. It can be understood that if the sixth horizontal drive component 820 does not receive a signal, it indicates that the test tube in the insert slot 211 is properly capped, and the sixth horizontal drive component 820 does not work, allowing the test tube to enter the next station.

[0057] Furthermore, to improve the convenience of test tube loading, such as... Figure 1 and Figure 8As shown, in one embodiment, the bead filling and capping machine 10 further includes a feeding mechanism 900. The feeding mechanism 900 includes a connecting rod 910, a blocking plate 920, and a feeding rack 930. The connecting rod 910 is installed on the worktable 100, and the feeding rack 930 is inclinedly arranged on the worktable 100. The feeding rack 930 is arranged adjacent to the embedding groove 211. The blocking plate 920 is installed on the connecting rod 910 and is located above the embedding groove 211. When the turntable 210 rotates, the blocking plate 920 abuts against the test tube. In this embodiment, the feeding mechanism 900 is located on the side of the tube arranging mechanism 800 away from the height detection mechanism 700. That is, the turntable 210 enters the feeding mechanism 900 after sequentially passing through the height detection mechanism 700 and the tube arranging mechanism 800. At this time, the defective products on the turntable 210 have been discharged by the tube arranging mechanism 800, and the test tubes arriving at the feeding mechanism 900 are good products. Specifically, the unloading rack 930 includes an unloading plate 931 and a support plate 932. The support plate 932 is mounted on the workbench. One end of the unloading plate 931 is connected to the workbench 100, and the unloading plate 931 is also connected to the end of the support plate 932, so that the unloading plate 931 is inclined on the workbench 100. The unloading plate is adjacent to the embedded groove 211, so that when the turntable 210 rotates to the position of the unloading plate 931, the embedded groove 211 is connected to the material passage of the unloading plate 931, and the blocking plate 920 passes through the connecting groove. The connecting rod 910 extends above the embedding groove 211. When the turntable 210 rotates to the position of the blocking plate 920, the test tube falls from the embedding groove 211 into the feeding plate 931 due to the force of the blocking plate 920. Since the feeding plate 931 is tilted, the test tube slides from the feeding plate 931 into the box below due to gravity, thus completing the feeding operation. The feeding mechanism 900 feeds the test tube, further improving the automation level and production efficiency of the bead filling and capping machine 10.

[0058] Furthermore, to ensure that the blocking plate 920 falls more effectively into the unloading rack 930 when it contacts the test tube, in one embodiment, the blocking plate 920 is arc-shaped and bends away from the unloading rack 930. It is understood that if the blocking plate 920 were strip-shaped, the test tube would experience a greater blocking force when it comes into contact with the blocking plate 920 due to the rotation of the turntable 210, making it easier for the test tube to bounce and fall into the unloading rack 930, which would be detrimental to its protection. By making the blocking plate 920 arc-shaped, when the test tube comes into contact with the blocking plate 920, it slides along the arc of the blocking plate 920 into the unloading rack 930 below, thus reducing the blocking force when the test tube contacts the blocking plate 920 and preventing the test tube from bouncing. Specifically, when the arc-shaped blocking plate 920 comes into contact with the rotating test tube, the test tube is blocked by the blocking plate 920 during rotation, causing the test tube to move along the arc of the blocking plate 920 and then slide off the embedded groove 211 into the lower feed plate 931. This reduces the force when the test tube comes into contact with the feed plate 931 and improves the protection effect on the test tube.

[0059] Compared with the prior art, this disclosure has at least the following advantages:

[0060] 1. The aforementioned bead filling and capping machine 10 uses a rotating drive 220 to drive the turntable 210 to rotate, causing the test tubes in the embedding groove 211 to pass sequentially through the bead filling mechanism 300, the liquid injection mechanism 400, and the capping mechanism 500. The bead filling mechanism 300 loads the grinding beads into the test tubes, the liquid injection mechanism 400 injects the test liquid into the test tubes, and finally the test tubes and bottle caps are tightened by the capping mechanism 500. Multiple processes are achieved through mechanization, reducing the number of manual operation steps and avoiding deviations caused by manual operation, thus improving production efficiency and product yield.

[0061] 2. In the aforementioned bead filling and capping machine 10, when the test tube rotates to the capping mechanism 500, the clamping component 520 first clamps the test tube in the embedding groove 211, and the capping component 530 clamps the bottle cap of the feeding conveying component 510 and moves it to the mouth of the test tube. Then, the capping component 530 screws the bottle cap and the test tube so that the bottle cap and the test tube are screwed and fixed. That is, the bottle cap is only clamped to the mouth of the test tube when it is screwed, which avoids the problem of the bottle cap falling off or being crooked when the bottle cap and the test tube are transported together, thereby improving the capping yield.

[0062] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure.
