Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a vaccine testing and delivery device with automatic return capability. Background Art

[0002] Currently, to improve the efficiency of doctors administering vaccines to patients, doctors are usually equipped with automated vaccine sorting boxes to eliminate the need for them to manually retrieve vaccines. Most existing automated vaccine sorting boxes consist of two parts: a sorting rack and a conveyor. The sorting rack automatically passes vaccine boxes containing vaccines to the conveyor, and the conveyor automatically transports the vaccine boxes to the doctor's vaccination station upon receiving them from the sorting rack.

[0003] However, vaccine boxes often deviate to varying degrees during their transfer from the sorting rack to the conveyor. If these vaccine boxes deviate too much, the identification codes on the vaccine boxes may be out of the detection area and difficult to detect. Consequently, the vaccine information contained in these deviated vaccine boxes will not only fail to be uploaded to the system for doctors to view the vaccine information, but will continue to be transmitted to the doctor's vaccination station by the conveyor.

[0004] As a result, more and more unidentified vaccine boxes will accumulate on the limited vaccination stations of doctors. If these unidentified vaccine boxes are not removed and redistributed in time, they will be mixed with identified vaccine boxes, which will interfere with the doctors' vaccination work and thus affect the overall vaccination efficiency.

[0025] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0026] Those skilled in the art should understand that, in the disclosure of this utility model, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0027] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0028] refer to Figures 1 to 3 The vaccine testing equipment with automatic return capability according to a preferred embodiment of the present invention will be described in detail below. The vaccine testing equipment with automatic return capability includes a loading rack 10, a feeding assembly 20 and a return mechanism 30. The loading rack 10 is provided with at least one loading layer 11, and each loading layer 11 extends at a predetermined angle in a downward direction to form at least one loading channel 1101. Each loading channel 1101 is used to load at least one material box 91. In addition, the loading rack 10 is also provided with a stop part 12 of predetermined height at the outlet of each loading channel 1101 to prevent the material box 91 from automatically leaving the loading channel 1101.

[0029] Understandably, the material box 91 loaded into the loading channel 1101 moves gradually from top to bottom to the outlet of the loading channel 1101 under the action of gravity in an inclined position. However, due to the obstruction of the baffle part 12, the material box 91 is temporarily restricted in the loading channel 1101. The unloading component 20 can remove the material box 91 restricted in the loading channel 1101 and move it to the return mechanism 30. Thus, after receiving the material box 91, the return mechanism 30 automatically detects the identification code on each material box 91 and transports the material box 91 with the detected identification code to the corresponding station 92, and returns the material box 91 with the undetected identification code to the loading rack 10.

[0030] It should be noted that each of the material boxes 91 has an identification code on each of its two sides for detection by the return mechanism 30. When the identification code on the two sides of the material box 91 is not facing the detection position of the return mechanism 30, the return mechanism 30 will not only not transport the material box 91 with the undetected identification code to the work station 92, but will also return the material box 91 with the undetected identification code to the inside of the loading rack 10. At this time, the material box 91 can be reloaded into the loading channel 1101 of the loading layer 11.

[0031] In a preferred embodiment, such as Figure 3 and Figure 7 As shown, the number of the loading layers 11 is set to three, and the loading layers 11 are evenly and intermittently arranged at the same vertical height along the top-to-bottom direction.

[0032] Specifically, the feeding assembly 20 includes at least one venting member 21 and the same number of connecting pipes 22 as the venting member 21. Each venting member 21 is configured to communicate with a port of one of the connecting pipes 22 to introduce gas into the connecting pipe 22. Each connecting pipe 22 extends from another port away from the venting member 21 toward the loading layer 11 to form at least one pipe branch 221 to communicate with one of the loading channels 1101, and each pipe branch 221 is configured to guide gas to blow vertically from bottom to top toward a material box 91 located in the loading channel 1101, so that each material box 91 at least partially passes over the baffle 12.

[0033] It is understood that each of the material boxes 91, at least partially passing the baffle 12, can gradually pass the baffle 12 under the action of gravity, thereby detaching itself from the loading channel 1101. Furthermore, when more than one material box 91 is loaded in each loading channel 1101, due to the inclined formation of the loading channel 1101, the material box 91 passing the baffle 12 is also pushed by the material box 91 located behind it under the action of gravity, thus making it easier for the material box 91 passing the baffle 12 to detach from the loading channel 1101.

[0034] Preferably, the ventilation component 21 is connected to the bottom of the material layer 11. Preferably, the ventilation component 21 includes, but is not limited to, a blower.

[0035] Preferably, the connection point between each pipe branch 221 and the loading channel 1101 is located at the outlet of the loading channel 1101 and close to the baffle 12. Thus, when the venting member 21 introduces gas into the connecting pipe 22, the gas exiting from the pipe branch 221 can directly blow the end of the material box 91 near the baffle 12 vertically, so that the end of the material box 91 near the baffle 12 is gradually lifted to a predetermined position above the baffle 12. Therefore, under the action of gravity, each material box 91 can more easily cross the baffle 12 and detach from the loading channel 1101.

[0036] Preferably, the feeding assembly 20 further includes a plurality of control units 23, each of the control units 23 being connected to one of the pipe branches 221, and each of the control units 23 being configured to open and close the inlet of gas to the loading channel 1101, thereby limiting the amount of gas to the loading channel 1101 to prevent excessive gas from blowing the material box 91 directly off the loading channel 1101.

[0037] Preferably, each of the control units 23 is implemented as a solenoid valve.

[0038] Specifically, the return mechanism 30 includes a material transfer unit 31, at least one detection unit 33, and a return component 33. The material transfer unit 31 has multiple material transfer sections 311 and multiple material unloading sections 312, wherein the material transfer sections 311 and the material unloading sections 312 are staggered and arranged on the same plane to receive the material box 91 that has exited the loading channel 1101, and the material transfer section 311 is also configured to roll and convey the material box 91 laterally. The detection unit 32 is arranged towards the material transfer section 311 to detect the identification code on the material box 91 conveyed by the material transfer section 311. When the detection unit 32 detects the identification code on the material box 91, the material transfer unit 31 is configured to shut down the material transfer section 311 and start the material unloading section 312 so that the material unloading section 312 rolls and conveys the material box 91 longitudinally to the work station 92. The return component 33 is disposed at the end position of the material box 91 conveyed by the material transfer section 311, and the return component 33 is configured to receive the material box 91 conveyed by the material transfer section 311 when the material transfer section 311 conveys the material box 91 to the end position and convey the material box 91 conveyed by the material transfer section 311 to the loading rack 10.

[0039] Those skilled in the art will understand that the material transfer unit 31 can transfer the material box 91 in two directions. When the detection unit 32 does not detect the identification code on the material box 91 transferred by the material transfer unit 311, the material transfer unit 31 does not start the unloading unit 312, and the material transfer unit 311 continues to transfer the material box 91 to the end position. At this time, the return member 33 receives the material box 91 transferred from the end position of the material transfer unit 311 and transfers the material box 91 whose identification code has not been detected by the detection unit 32 to the direction of the loading rack 10, so that the material box 91 can be reloaded into the loading channel 1101 of the loading layer 11.

[0040] In this way, the material box 91 that has not been identified by the identification code is difficult to be conveyed to the workstation 92 by the material transfer unit 31, thereby avoiding mixing with other material boxes 91 that have passed the detection at the workstation 92 and causing interference to the doctor's use. Accordingly, these material boxes 91 that have not been identified by the identification code will also be conveyed back to the loading rack 10 by the return material component 33, so as to be reloaded into the loading channel 1101 of the loading layer 11. Thus, each material box 91 after being conveyed by the return material component 33 can eventually be identified by the identification code by the detection unit 32 and then conveyed to the workstation 92 by the unloading part 312 of the material transfer unit 31 for the doctor's use.

[0041] Preferably, the material transfer unit 31 is configured as a cross-shaped conveying device composed of a roller and a conveyor belt, wherein the material transfer part 311 is configured as a roller and the material discharge part 312 is configured as a conveyor belt.

[0042] Preferably, the detection unit 32 is connected to the material transfer unit 31 and located at a predetermined position near the end of the material transfer section 311. Preferably, the detection unit 32 is configured as a scanner with identification function.

[0043] Preferably, the return material component 33 is implemented as a conveyor belt conveyor.

[0044] Furthermore, the return mechanism 30 also includes a receiving component 34, which is used to receive and transport the material box 91 that has detached from the loading channel 1101 to the material transfer unit 31.

[0045] Specifically, the receiving member 34 is maintained on the path of the material transfer section 311 receiving the material box 91, and the receiving member 34 has a receiving section 341, which is maintained at a predetermined height near the material layer 11 of the loading rack 10 to receive the material box 91 detached from the loading channel 1101, and the receiving section 341 is configured to move to the material transfer unit 31 to transport the material box 91.

[0046] In one embodiment, the receiving member 34 is configured as a robotic arm, and the receiving part 341 is configured as the end effector of the robotic arm, such as a suction cup. The suction cup moves with the robotic arm and is held above a material box 91 to be detached. Then, when the material box 91 detaches from the loading channel 1101, the robotic arm forms a negative pressure at the suction cup to adsorb the material box 91 and moves the adsorbed material box 91 toward the return mechanism 30.

[0047] Preferably, the welcoming portion 341 of the welcoming member 34 is disposed below the loading layer 11 of the loading rack 10, and the welcoming member 34 extends from the position of the welcoming portion 341 toward the position of the loading layer 11 at a predetermined angle in an upward direction to form a guide portion 342 for guiding the movement of the material box 91. The guide portion 342 defines a high end portion and a low end portion, wherein the high end portion is close to the material stop portion 12 of the loading rack 10, and the height of the high end portion is set to be at least level with the height of the material stop portion 12, and the height of the low end portion is set to be at least level with the height of the welcoming portion 341.

[0048] It is worth mentioning that the guide part 342 can also be formed by the loading rack 10 extending from the position of the loading layer 11 toward the position of the receiving part 341 in a downward direction at a predetermined angle.

[0049] Thus, when the material box 91 detaches from the loading channel 1101 and passes the baffle 12, each material box 91 can move along the guide 342 to the receiving part 341 under the action of gravity.

[0050] In one specific embodiment, such as Figure 2 , Figure 3 and Figure 7As shown, the receiving component 34 is configured as a conveyor belt conveying device, the receiving part 341 is configured as the conveyor belt of the conveyor belt conveying device, and the guide part 342 is configured as a guide ramp located on the side of the conveyor belt and close to the loading rack 10. Thus, when the material box 91 leaves the loading channel 1101, the material box 91 can fall onto the guide ramp under the action of gravity and move along the guide ramp toward the conveyor belt of the conveyor belt conveying device. In this way, the material box 91 that has moved to the conveyor belt is conveyed to the material transfer unit 31 along with the conveyor belt.

[0051] It is worth mentioning that the receiving component 34 can also be configured as a roller conveyor.

[0052] In one embodiment, the loading layer 11 is configured to move vertically so that the baffle portion 12 at the outlet of each loading channel 1101 is flush with the high end portion of the guide portion 342.

[0053] Conversely, in another embodiment, the receiving member 34 is configured to move vertically so that the high end of the guide 342 is level with the stop portion 12 at the outlet of each of the loading channels 1101.

[0054] It should be noted that if the guiding position of the guide part 342 is fixed, then when the number of the loading layers 11 exceeds one, the height at which the material box 91 located on the upper loading layer 11 detaches from the loading channel 1101 to move towards the receiving part 341 will increase. This makes it difficult for these material boxes 91 to maintain a consistent moving posture before moving to the receiving part 341, thus making it difficult to ensure that the posture of each material box 91 is consistent when it stops on the receiving part 341. The change in posture may cause the identification codes on both sides of the material box 91 to be covered on the receiving part 341, and the material box 91 1. The orientation of the material box 91 remains basically unchanged before and after being transferred to the material transfer unit 31. This causes the detection unit 32 to be unable to detect the identification codes on the material box 91 whose orientation has changed. Therefore, when the position of the receiving part 341 can be at least aligned with the material blocking part 12 of each material layer 11, the movement path of the material box 91 to the receiving part 341 is basically guided by the guiding part 342. Thus, the orientation of each material box 91 moving to the receiving part 341 remains basically consistent, thereby ensuring that the identification code on each material box 91 can be detected by the detection unit 32.

[0055] Furthermore, the automatically returnable vaccine testing equipment also includes a feeding device 40, which is used to automatically receive and load the material box 91 that has been conveyed by the return component 33 of the return mechanism 30 into the material channel 1101 of the material layer 11 of the material rack 10.

[0056] Specifically, the feeding device 40 includes a material-forming component 41, a feeding platform 42, and a feeding component 43. The material-forming component 41 is positioned below the end position of the return component 33 where the material box 91 is conveyed. The material-forming component 41 has an opening facing the end position of the return component 33 where the material box 91 is conveyed, for storing the conveyed material box 91. The material-forming component 41 also extends towards the feeding platform 42 to form a transmission channel 4102 communicating with the material box supply space 4101. Furthermore, the material-forming component 41 is configured to determine the position of each material box 91 to convey it to the feeding platform 42. The feeding platform 42 is connected to the outlet of the transmission channel 4102.

[0057] The feeding component 43 is provided with a movable arm 431 and a fixed part 432 movably connected to the end of the movable arm 431 in a vertical direction. The movable arm 431 is configured to carry the fixed part 432 to a position above the feeding platform 42 in a predetermined manner, so that the fixed part 432 can be moved to be positioned at both ends of a material box 91. The material box 91 positioned at the fixed part 432 is moved by the movable arm 431 to the inlet of the loading channel 1101 of the loading layer 11. After the fixed part 432 releases its positioning operation on the material box 91, the material box 91 can move under the action of gravity from the inlet of the loading channel 1101 to the outlet of the loading channel 1101 along the forming direction of the loading channel 1101.

[0058] Preferably, the material forming component 41 is implemented as a vibratory feeder.

[0059] Preferably, the feeding platform 42 has a pair of positioning parts 421 at its top. The two positioning parts 421 are arranged opposite to each other and spaced apart to form a guide channel 42101 and a limiting channel 42102. The guide channel 42101 is located between the limiting channel 42102 and the transmission channel 4102 and communicates with both the limiting channel 42102 and the transmission channel 4102. The inner diameter of the guide channel 42101 is set to gradually decrease from the outlet of the transmission channel 4102 to the inlet of the limiting channel 42102. The inner diameter of the limiting channel 42102 is set to be adapted to the size of each material box 91.

[0060] It is understood that when the material box 91 moves from the outlet of the transmission channel 4102 to the guide channel 42101, the material box 91 can gradually move along the inner wall forming the guide channel 42101 towards the limiting channel 42102. Due to the size of the inner diameter of the limiting channel 42102, each material box 91 that detaches from the limiting channel 42102 maintains a consistent posture when positioned by the feeding member 43.

[0061] In a preferred embodiment, such as Figure 2 and Figure 3 As shown, the feeding platform 42 is configured as a conveying device to automatically convey the material box 91 that has exited the conveying channel 4102 to the feeding component 43.

[0062] In one embodiment, the feeding component 43 is configured as a robotic arm, and the movable arm 431 is configured as the arm portion of the robotic arm, such as... Figure 6 As shown, the material fixing part 432 is configured as a suction cup installed at the end of the arm part, and when the bottom end of the suction cup is close to the material box 91 on the feeding platform 42, the suction cup is set at the bottom end to form a negative pressure to adsorb the material box 91.

[0063] It is worth mentioning that the material setting part 432 can also be configured as a tool with a clamping function.

[0064] Furthermore, the feeding device 40 also includes an adjusting member 44, which is used to further adjust the position of the feeding member 43 as a whole when the material box 91 is positioned by the material fixing part 432 of the feeding member 43, so that the positioned material box 91 can be moved to the inlet of the material channel 1101 of the different material layers 11 to complete the feeding operation.

[0065] Preferably, the adjusting member 44 includes a horizontal adjusting unit 441 and at least one vertical adjusting unit 442, wherein each vertical adjusting unit 442 is movably connected to the horizontal adjusting unit 441 in a horizontal direction, and the manner in which the horizontal adjusting unit 441 moves the vertical adjusting unit 442 is consistent with the arrangement of multiple loading channels 1101 in a single loading layer 11. The feeding member 43 is movably connected to the vertical adjusting unit 442 in a vertical direction, and the manner in which the vertical adjusting unit 442 moves the feeding member 43 is consistent with the arrangement of the multiple loading layers 11.

[0066] In a specific example, such as Figure 6As shown, the horizontal adjustment unit 441 is configured as a driving member 4411, a driving shaft 4412, a moving block 4413, and a guide rail 4414. The driving shaft 4412 is synchronously rotatably connected to the driving member 4411, and is threadedly connected to the moving block 4413. The extending direction of the driving shaft 4412 is consistent with the direction in which the single loading layer 11 arranges the plurality of loading channels 1101. The moving block 4413 is configured to be movably connected to the guide rail 4414 when the driving member 4411 drives the driving shaft 4412. The extending direction of the guide rail 4414 is parallel to the extending direction of the driving shaft 4412 to limit the movement of the moving block 4413.

[0067] Thus, the feeding component 43 as a whole can move along the direction consistent with the extension direction of the drive shaft 4412 and the guide rail 4414 when the drive member 4411 rotates the drive shaft 4412 synchronously, so that the material box 91 positioned by the fixed part 432 is moved to the inlet of the different material channels 1101 of the single material layer 11.

[0068] In a preferred embodiment, such as Figure 6 As shown, each of the vertical adjustment units 442 is implemented to include a hydraulic cylinder, and the telescopic end of each hydraulic cylinder is connected to the bottom of the feeding member 43 so that when the telescopic end of the hydraulic cylinder extends or retracts, the feeding member 43 is driven to move in the vertical direction, so that the material box 91, which is positioned by the fixed part 432, is moved to the inlet of the loading channel 1101 of the loading layer 11 at different heights.

[0069] It is worth mentioning that, in another variant embodiment, the vertical adjustment unit 442 can be implemented as a lifting device consisting of a lead screw drive component.

[0070] In this way, the feeding component 43 can accurately carry the positioned material box 91 to the inlet of the loading channel 1101 at different heights and different horizontal positions.

[0071] More preferably, the loading rack 10 also forms a processing chamber 101 for the installation of the feeding device 40. Furthermore, the loading rack 10 also has a switch door 13 on the inner wall forming the processing chamber 101 to close and open the entrance to the processing chamber 101.

[0072] As a further preferred embodiment, the return material member 33 at least partially penetrates the processing chamber 101 to convey the material box 91 to the material preparation member 41 of the feeding device 40.

[0073] Furthermore, the automatically returnable vaccine testing equipment also includes an identification inspection component 50, which is used to detect whether each of the material boxes 91 has an identification code on both sides before being loaded into the material loading rack 10, thereby ensuring that the material boxes 91 detected by the detection unit 32 of the return mechanism 30 have identification codes on both sides.

[0074] Preferably, the identification inspection component 50 includes a pair of inspection units 51 and a collector 52, wherein the two inspection units 51 are arranged opposite to and spaced apart on top of the collector 52 to form an inspection space 5101, and the inspection space 5101 is located on the path of the feeding member 43 carrying the material box 91 to detect the identification codes on both sides of the material box 91. The collector 52 has a collection space 5201 with an opening facing the location where the inspection space 5101 is formed. The feeding member 43 is controllably connected to the inspection units 51, so that when the inspection units 51 detect the identification codes on both sides of the material box 91, the material box 91 is moved to the inlet of the loading channel 1101 by means of the feeding member 43.

[0075] When the inspection unit 51 detects the identification codes on both sides of the material box 91, the feeding component 43 releases the positioning operation of the material box 91, so that the material box 91 falls from the inspection space 5101 to the collection space 5201 under the action of gravity.

[0076] Preferably, both the inspection unit 51 and the collector 52 are located in the processing chamber 101.

[0077] Preferably, the inspection unit 51 is implemented as a sensor with identification and control functions.

[0078] In addition, the automatically returnable vaccine testing equipment also includes a material guiding unit 60. Preferably, the material guiding unit 60 is disposed in the processing chamber 101, and the material guiding unit 60 is held above the material preparation component 41 and located below the end of the material box 91 conveyed by the return component 33, forming a funnel-shaped material guiding channel 601 to guide the material box 91 to move from top to bottom into the material box supply space 4101 of the material preparation component 41 under the action of gravity.

[0079] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from the stated principles.
