Description

Technical Field

[0001] This utility model relates to the technical field of opening the cap of a sampling tube, and in particular to an efficient cap-opening device for a sampling tube. Background Technology

[0002] Sampling tubes are used to collect samples, including blood or saliva. The tubes serve to hold the samples, facilitating their transfer to the laboratory and enabling staff to use specialized instruments to analyze the content or concentration of certain substances within the samples. Sampling tubes are made of materials such as glass and plastic. The structure of a plastic sampling tube is shown below. Figures 1-2 As shown, it includes a plastic tube 1 and a plastic cap 2. The bottom of the plastic tube 1 is closed and the top is open. A sample from the human body is pre-collected inside the plastic tube 1. The plastic cap 2 closes the opening of the plastic tube 1 and is press-fitted to the plastic tube 1.

[0003] When the laboratory staff receive a certain number of such Figures 1-2 After the sampling tubes are shown, the staff need to open the caps of each sampling tube, that is, to remove the plastic caps 2 on the plastic tube 1, so that the staff can use special instruments to test the samples inside the plastic tube 1.

[0004] The method for opening all received sampling tubes in the laboratory is as follows: S1, the staff first takes out a sampling tube to be opened; S2, the staff holds the plastic tube body 1 of the sampling tube with their left hand, and then uses their right hand to pull the plastic cap 2 off the plastic tube body 1; after pulling it off, the staff throws the plastic cap 2 into the waste bin, and then places the plastic tube body 1 at the detection station of the special instrument, thus completing the opening of the first sampling tube; S3, the staff repeats steps S1 to S2 multiple times to open all received sampling tubes in the laboratory.

[0005] However, while this method can open a batch of sampling tubes, it still reveals the following technical shortcomings in actual operation:

[0006] I. In step S2, the plastic tube body 1 of the sampling tube needs to be held manually with the left hand, and then the plastic cap 2 needs to be pulled off the plastic tube body 1 with the right hand to complete the opening of a sampling tube. The number of sampling tubes to be opened in a day is as high as 200. The staff open them one by one, which not only increases the workload of the staff, but also makes it take a long time to open all the sampling tubes. This undoubtedly reduces the efficiency of opening the sampling tubes.

[0007] II. In step S2, after the plastic cap 2 is pulled out of the plastic tube 1, the staff still need to manually throw the plastic cap 2 into the waste bin, which undoubtedly increases the workload of the staff.

[0008] Therefore, there is an urgent need for a highly efficient cap-opening device that can greatly reduce the workload of staff and significantly improve the efficiency of opening sampling tubes. Utility Model Content

[0009] The purpose of this invention is to overcome the shortcomings of the prior art and provide a highly efficient sampling tube opening device that greatly reduces the workload of staff and greatly improves the efficiency of opening the sampling tube.

[0010] The purpose of this utility model is achieved through the following technical solution: a high-efficiency capping device for a sampling tube, which includes a machine base, a negative pressure fixing component set on the machine base for fixing the plastic tube body of the sampling tube, and a picking and throwing component for automatically pulling the plastic cap off the plastic tube body and automatically throwing off the plastic cap.

[0011] The negative pressure fixing assembly includes two brackets fixed on the machine base, a positioning seat fixed between the two brackets, and a lifting cylinder fixed on the machine base. The positioning seat has a through hole penetrating its top and bottom surfaces. The lifting cylinder is located directly below the through hole of the positioning seat.

Multiple vacuum holes communicating with its inner cavity are opened on the top surface of the suction cup. A flexible hose is connected to the bottom of the suction cup. The other end of the flexible hose is connected to a vacuum pump.

[0012] The extraction and throwing assembly includes a main cylinder fixed on the machine base. A lifting plate is fixed on the working end of the piston rod of the main cylinder. A secondary cylinder is fixed on the bottom surface of the left end of the lifting plate. The piston rod of the secondary cylinder passes through the lifting plate upward, and an arc-shaped block is fixed on its extension end. A pulling plate extending to the left is hinged to the top surface of the right end of the lifting plate. The bottom surface of the extension end of the pulling plate is supported on the arc-shaped block. A U-shaped groove is opened at the left end of the pulling plate. The U-shaped groove is located directly above the through hole, and the width of the U-shaped groove is equal to the outer diameter of the plastic tube of the sampling tube.

[0013] Support legs are fixed on the bottom surface of the machine tool and at its left and right ends.

[0014] The outer diameter of the suction cup is smaller than the diameter of the through hole, and the vacuum pump is fixed on the table of the machine.

[0015] Protective plates are fixed on the top surface of the actuating plate and on its front and rear sides.

[0016] A hinge seat is fixed on the top surface of the right end of the lifting plate, and a support plate is fixed on the bottom of the actuating plate. The actuating plate is hinged to the support plate via the hinge seat.

[0017] A waste basket located to the right of the actuation plate is placed on the top surface of the machine.

[0036] The present invention will be further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following description:

[0037] like Figures 3-9 As shown, a high-efficiency capping device for a sampling tube includes a machine base 3, a negative pressure fixing component 4 mounted on the machine base 3 for fixing a plastic tube body 1 of the sampling tube, and a pulling and throwing component 5 for automatically pulling the plastic cap 2 off the plastic tube body 1 and automatically throwing off the plastic cap 2; support legs are fixed on the bottom surface of the machine base 3 and at its left and right ends.

[0038] The negative pressure fixing assembly 4 includes two brackets fixed on the machine base 3, a positioning seat 6 fixed between the two brackets, and a lifting cylinder 7 fixed on the machine base 3. The positioning seat 6 has a through hole 8 that penetrates its top and bottom surfaces. The lifting cylinder 7 is located directly below the through hole 8 of the positioning seat 6. A suction cup 9 is fixed on the working end of the piston rod of the lifting cylinder 7. The suction cup 9 extends into the through hole 8. The outer diameter of the suction cup 9 is smaller than the diameter of the through hole 8. A plurality of vacuum holes communicating with its inner cavity are opened on the top surface of the suction cup 9. A hose 10 is connected to the bottom of the suction cup 9. The other end of the hose 10 is connected to a vacuum pump. The vacuum pump is fixed on the table surface of the machine base 3.

[0039] The extraction and throwing assembly 5 includes a main cylinder 11 fixed on the machine base 3. A lifting plate 12 is fixed to the working end of the piston rod of the main cylinder 11. A secondary cylinder 13 is fixed to the bottom surface of the left end of the lifting plate 12. The piston rod of the secondary cylinder 13 passes upward through the lifting plate 12, and an arc-shaped block 14 is fixed to its extended end. A pulling plate 15 extending to the left is hinged to the top surface of the right end of the lifting plate 12. Protective plates 17 are fixed to the top surface of the pulling plate 15 and on both its front and rear sides. The bottom surface of the extended end of the pulling plate 15 is supported on the arc-shaped block 14. A U-shaped groove 16 is opened at the left end of the pulling plate 15. The U-shaped groove 16 is located directly above the through hole 8, and the width of the U-shaped groove 16 is equal to the outer diameter of the plastic tube body 1 of the sampling tube. A waste basket 19 located to the right of the pulling plate 15 is placed on the top surface of the machine base 3.

[0040] A hinge seat 18 is fixed on the top surface of the right end of the lifting plate 12, and a support plate is fixed on the bottom of the actuating plate 15. The actuating plate 15 is hinged to the support plate hinge seat 18.

[0041] The high-efficiency lid opening device also includes a controller. The controller is electrically connected to the lifting cylinder 7, the main cylinder 11, the auxiliary cylinder 13 and the vacuum pump via signal lines. The operator can control the extension or retraction of the piston rods of the lifting cylinder 7, the main cylinder 11 and the auxiliary cylinder 13 through the controller, and can also control the start or stop of the vacuum pump, which facilitates the operation of the operator.

[0042] The method for opening all received sampling tubes in the laboratory is as follows:

[0043] S1. The specific steps for opening the first sampling tube are as follows:

[0044] S11, The staff took out a... Figures 1-2 The sampling tube to be opened is shown in the diagram. The plastic tube body 1 of the sampling tube is passed sequentially from top to bottom through the U-shaped groove 16 of the actuating plate 15 and the through hole 8 of the positioning seat 6. Finally, the bottom surface of the plastic tube body 1 is supported on the top surface of the suction cup 9, thus achieving the positioning of the sampling tube. Figures 10-11 As shown, at this time, the bottom surface of the plastic tube body 1 of the sampling tube completely blocks all the vacuum holes on the suction cup 9, and at the same time, the bottom surface of the plastic cap 2 of the sampling tube is just supported on the top surface of the actuating plate 15.

[0045] S12. Control the vacuum pump to start. The vacuum pump evacuates the inner cavity of the hose 10 and the suction cup 9 and the vacuum hole on the suction cup 9. Under negative pressure, the plastic tube 1 is adsorbed and fixed on the suction cup 9.

[0046] S13. The piston rod of the main cylinder 11 extends upward, and the piston rod drives the lifting plate 12 to move upward. The lifting plate 12 drives the auxiliary cylinder 13, the arc block 14, the hinge seat 18 and the pulling plate 15 to move upward synchronously. During the upward movement, the pulling plate 15 gradually pulls the plastic cover 2 off the plastic tube 1. When the piston rod of the main cylinder 11 is fully extended, the plastic cover 2 is separated from the plastic tube 1, thus realizing the opening of the first sampling tube. At this time, the plastic cover 2 stays in the area enclosed by the pulling plate 15 and the two protective plates 17.

[0047] As can be seen from step S1, this cap-opening device only needs to first use the suction cup 9 to adsorb and fix the plastic tube body 1 of the sampling tube, and then the piston rod of the main cylinder 11 extends upward to make the pulling plate 15 move upward, thereby making the pulling plate 15 pull the plastic cap 2 off the plastic tube body 1, thus realizing the automatic removal of the plastic cap 2 from the plastic tube body 1. Figure 12As shown, this completes the automatic opening of the sampling tubes. Therefore, it is clear that there is no need for staff to manually open the sampling tubes, which not only greatly reduces the workload of staff but also allows all received sampling tubes to be opened in a short time, thus significantly improving the efficiency of opening the sampling tubes.

[0048] S2. Throwing of Plastic Cover 2: The piston rod of the auxiliary cylinder 13 extends upward, driving the arc-shaped block 14 to move upward. The arc-shaped block 14 pushes up the actuating plate 15, which rotates clockwise around the hinge seat 18. When the actuating plate 15 rotates to an inclined state, the plastic cover 2 on the actuating plate 15 slides down along the length of the actuating plate 15 into the waste bin 19, in the following direction. Figure 13 As shown by the middle arrow, this allows the plastic cap 2 to be thrown.

[0049] As can be seen from step S2, this cap-opening device only needs to control the auxiliary cylinder 13 to drive the arc-shaped block 14 to move upward, so that the pulling plate 15 tilts around the hinge seat 18, thereby automatically throwing the removed plastic cap 2 into the waste bin 19. Therefore, it can be seen that there is no need for the staff to manually throw the plastic cap 2 into the waste bin 19 after opening the cap, thus further reducing the workload of the staff.

[0050] S3. Removal of the plastic tube 1 containing the sample: The vacuum pump is turned off, the suction cup 9 no longer holds the plastic tube 1, and then the piston rod of the lifting cylinder 7 is extended upward. The piston rod drives the suction cup 9 to move upward, and the suction cup 9 drives the plastic tube 1 to move upward, so that the plastic tube 1 is removed from the positioning seat 6. After it is removed, the staff places the plastic tube 1 containing the sample at the detection station of the special instrument.

[0051] S4. By repeating steps S1 to S3 multiple times, all the sampling tubes received in the laboratory can be opened, and the removed plastic caps 2 can be automatically thrown into the waste bin 19.

[0052] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
