Description
Technical Field
[0001] This invention relates to the field of test tube dispensing technology, specifically a device for automatically dispensing blood test tubes. Background Technology
[0002] Clinical treatment carts and emergency room treatment carts require various blood drawing tubes. These tubes are typically arranged on trays and are categorized by the color of their caps: red, purple, yellow, and blue. However, once the tubes are used up, they need to be replenished manually. Since each box contains tubes with caps of the same color, it is often necessary to replenish one or more types of caps separately. After all tubes are used up, they should be arranged according to need. Please refer to [link / reference needed]. Figure 8 It's not convenient to use. Summary of the Invention
[0003] The purpose of this invention is to provide an automatic blood tube dispensing device to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution:
[0005] An automatic blood tube dispensing device includes a visual image processing control mechanism and a configuration compartment. A lens extension compartment is fixedly connected to the top side of the configuration compartment. An inlet slot is opened on the side of the configuration compartment. A sliding guide rail is fixedly connected to the outside of the inlet slot. A tray is slidably connected inside the sliding guide rail. The tray is located directly below the lens extension compartment.
[0006] The configuration compartment is equipped with a material discharge module, a support plate, a pneumatic push module, an alignment perforated plate, and a material distribution module. The alignment perforated plate is located above the tray, and the material distribution modules are arranged in pairs on top of the alignment perforated plate in a stepped manner.
[0007] The discharge module includes a vertical compartment, a bottom guide arc plate, and a top guide arc plate. The bottom and top guide arc plates are distributed vertically to form a guide track that communicates with the bottom opening of the vertical compartment. The bottom and top guide arc plates guide the test tube from horizontal to vertical.
[0008] The surface of the tray has several tube grooves arranged in a matrix. The bottom surfaces of two adjacent columns of tube grooves are affixed with different primary markers, and different tube grooves in the same column are affixed with different secondary markers.
[0009] The support plate is located above the fabric module, and the pneumatic push module matrix is distributed on the surface of the support plate. Each pneumatic push module corresponds to the secondary marker, and the up and down movement of the pneumatic push module is controlled by the lens extension chamber and the visual image processing control mechanism.
[0010] As a further embodiment of the present invention: the top surface of the bottom guide arc plate is provided with a bottom guide groove, the bottom surface of the top guide arc plate is provided with a top guide groove, and the width of the top guide groove is greater than the width of the bottom guide groove.
[0011] As a further embodiment of the present invention: the holes on the surface of the alignment plate correspond to the grooves in the tube.
[0012] As a further embodiment of the present invention: the fabric module consists of two horizontally distributed conveyor belts, which are driven to rotate forward and reverse by a servo motor. Several equally spaced clamps are fixedly connected to the outer wall of the conveyor belts. A small arc portion is fixedly connected to the end of the clamp near the inlet slot, and a large arc portion is fixedly connected to the end of the clamp away from the inlet slot.
[0013] As a further aspect of the present invention: the distance between the two large arc portions that are opposite each other in the horizontal direction is less than the diameter of the test tube body, and the distance between the two small arc portions that are opposite each other in the horizontal direction is less than the diameter of the test tube body.
[0014] As a further aspect of the present invention, the card block is made of an elastic material.
[0015] As a further embodiment of the present invention: the edges of the card block, the small arc portion, and the large arc portion are provided with pushing slopes.
[0016] As a further aspect of the present invention, the method of using the device includes:
[0017] S1: Insert the used or unused tray into the sliding guide rail, capture the surface image information of the tray through the lens extension chamber, and transmit the data to the computer to collect the image of the tube groove that is not blocked by the test tube.
[0018] S2: Push the pallet into the configuration compartment through the sliding guide rail and the inlet slot. The vision image processing control mechanism switches the corresponding air-driven push module to the ready state based on the primary and secondary markers in the slot.
[0019] S3: The tray is pushed to the bottom of the alignment plate via the sliding guide rail. The test tubes at the edges of the bottom guide arc plate and the top guide arc plate are driven to slide inward in sequence by the fabric module. The test tubes are located directly above the holes of the alignment plate. The air-driven push module in the ready state is turned on. In the pushing state of the push end of the air-driven push module, the test tubes are sent into the tube groove.
[0020] S3: The fabric module reverses, pushing the test tube in the opposite direction through the top and bottom guide arc plates, so that the fabric module does not contain a test tube when not in use, ensuring that the fabric module is in a full test tube state after one rotation cycle when in use.
[0021] Compared with the prior art, the beneficial effects of the present invention are:
[0022] Using visual acquisition and control, the corresponding primary and secondary markers are clearly and easily obtained by utilizing the obstruction effect of the test tubes and the tube slots. By using the correspondence between the markers and the pneumatic push module, the reciprocating gravity-guided delivery and full-tube arrangement method simplifies the control process. The test tubes are pushed into the corresponding tube slots by the pneumatic push module, realizing the functions of full and partial supplementation, and improving the convenience of use for doctors.

[0033] Please see Figures 1-7 :
[0034] Example 1:
[0035] In this embodiment, a visual image processing control mechanism is included, as well as a configuration compartment 1. A lens extension compartment 2 is fixedly connected to the top side of the configuration compartment 1. An inlet slot 11 is opened on the side of the configuration compartment 1. A sliding guide rail 3 is fixedly connected to the outside of the inlet slot 11. A tray 4 is slidably connected inside the sliding guide rail 3. The tray 4 is located directly below the lens extension compartment 2.
[0036] In this embodiment, the configuration compartment 1 serves as a sealed protective structure. The lens extension compartment 2 extends outward from the top side of the configuration compartment 1, and a camera is installed at the bottom of the lens extension compartment 2. The camera is connected to the computer for data transmission. The visual image processing and control mechanism includes a computer, a controller, and software. The software processes the images captured by the camera, determines the corresponding empty areas on the tray 4, and after analysis by the software, uses the controller to control the test tubes to be filled into the corresponding areas, thereby achieving the filling purpose.
[0037] In this embodiment, the configuration compartment 1 is equipped with a discharge module 5, a support plate 6, a pneumatic push module 7, an alignment perforated plate 8, and a material distribution module 9. The alignment perforated plate 8 is located above the tray 4, and the material distribution modules 9 are arranged in pairs on top of the alignment perforated plate 8. The material distribution modules 9 are stepped.
[0038] In this embodiment, the discharge module 5 synchronously stores and transports a large number of test tubes of the same color, so that multiple test tubes of the same color can be replenished at once when materials are replenished. The test tubes are arranged longitudinally inside the vertical compartment 51. The support plate 6 provides a fixed support surface for the pneumatic push module 7, and the lower output end of the pneumatic push module 7 passes through the support plate 6 and acts on the surface of the test tubes.
[0039] In this embodiment, since the fabric module 9 is a closed-loop conveyor belt, it is arranged in a stepped pattern to achieve horizontal spatial avoidance, thus achieving a small-area horizontal distribution. To ensure the stability of the test tube transport, the movable end of the pneumatic push module 7 is fixed with an adhesive part, and a damping surface is fixedly connected to the inner wall of the tube groove 41. The adhesive part adheres to the top surface of the test tube and pushes the test tube downward. The bottom of the test tube is clamped in conjunction with the tube groove 41. When the adhesive part separates from the test tube, due to the high friction between the tube groove 41 and the test tube, the adhesive part can separate from the test tube.
[0040] In this embodiment, the discharge module 5 includes a vertical compartment 51, a bottom guide arc plate 52, and a top guide arc plate 53. The bottom guide arc plate 52 and the top guide arc plate 53 are distributed vertically to form a guide track that communicates with the bottom opening of the vertical compartment 51. The bottom guide arc plate 52 and the top guide arc plate 53 guide the test tube from horizontal to vertical.
[0041] In this embodiment, the top of the vertical compartment 51 is an open structure, allowing test tubes to be easily placed inside. The bottom guide plate 52 and the top guide plate 53 are arc-shaped, and both ends of the guide track are open structures. The connection points between the bottom guide plate 52, the top guide plate 53, and the fabric module 9 have a horizontal surface, allowing the test tubes to overcome gravity and enter the horizontal surface under the guidance of the bottom guide plate 52 and the top guide plate 53. The alignment plate 8 can act on the test tube from the side of the guide track, thereby pushing the end of the test tube to one side.
[0042] In this embodiment, the main purpose of setting the bottom guide arc plate 52 and the top guide arc plate 53 is to realize the delivery and return of the test tubes. When delivering, the material distribution module 9 can act on the test tube to transport the test tube to the outside. When returning, the material distribution module 9 reverses and pushes the test tube to the bottom guide arc plate 52 and the top guide arc plate 53, so that the test tube enters the interior of the vertical compartment 51 in the opposite direction, thereby ensuring that the interior is full of test tubes each time the material distribution module 9 performs the forward delivery.
[0043] In this embodiment, the surface of the tray 4 is provided with a number of tube grooves 41 distributed in a matrix. The bottom surfaces of two adjacent columns of tube grooves 41 are affixed with different primary markers, and different tube grooves 41 in the same column are affixed with different secondary markers.
[0044] In this embodiment, the tube groove 41 allows the test tube to be fixed vertically. In order to simplify the control process of the system, a primary marker is attached to the tube groove 41. The primary marker can be a color that corresponds to the color of the test tube cap. The secondary marker can be a number or a letter. Based on the color and number, the corresponding air-driven push module 7 can be identified, thereby placing the test tube into the corresponding tube groove 41 to complete the replenishment.
[0045] In this embodiment, the support plate 6 is located above the fabric module 9, and the pneumatic push modules 7 are matrixed on the surface of the support plate 6. Each pneumatic push module 7 corresponds to a secondary marker, and the up and down movement of the pneumatic push module 7 is controlled by the lens extension chamber 2 and the visual image processing control mechanism.
[0046] In this embodiment, the main body of the pneumatic push module 7 is composed of a piston. The fixed part of the piston is fixedly connected to the support plate 6. The movable part is connected to the bottom of the piston by a spring. Each air pipe of the pneumatic push module 7 is equipped with a corresponding solenoid valve and an exhaust valve. When controlling, it is only necessary to open the air passage solenoid valve to ensure smooth airflow. Under high air pressure, the movable part descends and contacts the test tube. When venting, the piston returns to its original position after the exhaust solenoid valve is opened.
[0047] In this embodiment, the top surface of the bottom guide arc plate 52 is provided with a bottom guide groove 521, and the bottom surface of the top guide arc plate 53 is provided with a top guide groove 531. The width of the top guide groove 531 is greater than the width of the bottom guide groove 521.
[0048] In this embodiment, the bottom guide arc plate 52 and the top guide arc plate 53 have corresponding bottom guide grooves 521 and top guide grooves 531, respectively. The bottom guide grooves 521 and top guide grooves 531 are aligned to form a through groove. The top guide groove 531 needs to accommodate the test tube cap, while the bottom guide groove 521 needs to accommodate the test tube base. Therefore, the width of the top guide groove 531 is greater than the width of the bottom guide groove 521.
[0049] In this embodiment, the holes on the surface of the alignment plate 8 correspond to the tube groove 41. The reason for this arrangement is to ensure that if the test tube can descend smoothly, it will pass through the holes of the alignment plate 8, thereby aligning with the tube groove 41 and inserting the test tube into the interior of the tube groove 41.
[0050] In this embodiment, the fabric module 9 consists of two horizontally distributed conveyor belts 91. The conveyor belts 91 are driven to rotate forward and reverse by a servo motor. Several equally spaced locking blocks 92 are fixedly connected to the outer wall of the conveyor belts 91. A small arc portion 921 is fixedly connected to the end of the locking block 92 near the inlet slot 11, and a large arc portion 922 is fixedly connected to the end of the locking block 92 away from the inlet slot 11.
[0051] In this embodiment, please refer to Figure 7 , Figure 7 The lower end is near the inlet slot 11. Therefore, in this configuration, the smaller arc 921 is shorter, making it easier to enter the front of the test tube, while the larger arc 922 is longer, making it easier to pull the pipe out of the track. First, the clamping block 92 is made of rubber, which can deform. At the same time, damping layers or elastic baffles are provided on the upper and lower end faces of the track to increase the damping of the test tube and prevent the pipe from shifting during the clamping process of the clamping block 92, which would result in incomplete clamping by the clamping block 92.
[0052] In this embodiment, the distance between the two large arc portions 922 that are opposite each other in the horizontal direction is smaller than the diameter of the test tube body, and the distance between the two small arc portions 921 that are opposite each other in the horizontal direction is smaller than the diameter of the test tube body; the clamping action of the locking block 92 can ensure bidirectional pushing of the test tube forward and backward.
[0053] In this embodiment, the edges of the card block 92, the small arc portion 921, and the large arc portion 922 are provided with pushing slopes 923. The pushing slopes 923 are mainly to make it easier for the air-driven pushing module 7 to push the test tube from top to bottom. The cap at the top of the test tube has a gap difference with the tube wall. The pushing slopes 923 allow the gap at the edge of the cap to pass smoothly between the two card blocks 92.
[0054] How to use:
[0055] S1: Insert the used or unused tray 4 into the sliding guide rail 3, capture the surface image information of the tray 4 through the lens extension chamber 2, and transmit the data to the computer to collect the image of the tube groove 41 that is not blocked by the test tube.
[0056] S2: The pallet 4 is pushed into the configuration compartment 1 through the sliding guide rail 3 and the inlet slot 11. The visual image processing control mechanism switches the corresponding air-driven push module 7 to the ready state according to the primary and secondary markers in the slot 41.
[0057] S3: The tray 4 is pushed to the bottom of the alignment plate 8 via the sliding guide rail 3. The test tubes at the edges of the bottom guide arc plate 52 and the top guide arc plate 53 are driven to slide inward in sequence by the fabric module 9. The test tubes are located directly above the holes of the alignment plate 8. The air-driven push module 7 in the ready state is turned on. In the pushing state of the push end of the air-driven push module 7, the test tubes are sent into the tube groove 41.
[0058] S4: The fabric module 9 reverses, pushing the test tube in the opposite direction through the top guide arc plate 53 and the bottom guide arc plate 52, so that the fabric module 9 does not contain a test tube when it is not in use, ensuring that the fabric module 9 is in a full test tube state after one rotation cycle when in use.
[0059] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
