Description

Batch tube dispenser and automatic test tube feeding system for automatic test tube labeling machine Technical Field

[0001] This application relates to the field of medical devices, and more particularly to a batch tube dispenser and an automatic tube feeding system for an automatic tube labeling machine. Background Technology

[0002] In testing experiments in fields such as medicine, biology, and food, it is often necessary to label hundreds or even thousands of test tubes to distinguish different sample information and avoid confusion. With the development of automation technology, automatic test tube labeling machines have gradually replaced manual labeling and become the mainstream equipment. However, the feeding process of current automatic test tube labeling machines still has significant shortcomings, making it difficult to match the high-speed labeling capabilities of the machines, which has become a key bottleneck restricting overall operational efficiency.

[0003] Existing test tube loading methods are mainly divided into two categories: manual single-tube loading and loading assisted by simple tools. Manual single-tube loading requires operators to remove each test tube from the foam test tube holder and place it into the loading track of the automatic labeling machine. This is not only time-consuming and labor-intensive, but also prone to operator fatigue due to prolonged repetitive operation, resulting in problems such as test tubes falling or being placed in the wrong position. At the same time, manual contact with test tubes may also increase the risk of sample contamination. While loading assisted by simple tools (such as ordinary test tube clamps and trays) can achieve the synchronous transfer of a small number of test tubes, it has many drawbacks: First, it cannot accurately control the posture of the test tubes. When transferring them to the loading station of the labeling machine, the test tubes are prone to tilting or inverting, requiring manual adjustment. This cannot meet the precise requirements of the automatic labeling machine for test tube posture. Second, the gripping stability is poor. Ordinary tools only fix the test tubes by simple clamping or lifting, and the test tubes are prone to shaking and falling off during the transfer process.

[0004] Therefore, how to achieve efficient batch grasping and stable posture maintenance of test tubes is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] This application provides a batch tube dispenser and an automatic tube feeding system for an automatic tube labeling machine to improve feeding efficiency and stability.

[0006] To address the aforementioned technical problems, this application discloses the following technical solution: On one hand, it provides a batch tube extractor for an automatic test tube labeling machine, comprising: a long, strip-shaped main body, the interior of which forms a cap cavity; one end of the main body is closed, and the other end is open, forming a cap inlet / outlet communicating with the cap cavity; the bottom of the main body is open, forming a tube body clearance opening communicating with the cap cavity; the two sides of the tube body clearance opening are bent inwards to form retaining edges for limiting cap detachment; and a clamping module, the clamping module including a clamping handle, a connecting post, an elastic reset member, and a tube. The cap clamping strip has one end of the connecting post fixedly connected to the clamping handle, and the other end passing through the top wall of the cap cavity and fixedly connected to the cap clamping strip located inside the cap cavity. The elastic reset member elastically acts on the clamping handle, causing the clamping handle to switch between a clamping state and a released state. The clamping module is configured to: by pressing the clamping handle to compress the elastic reset member, drive the cap clamping strip to move towards the sidewall, thereby clamping and fixing the test tube cap contained in the cap cavity between the cap clamping strip and the sidewall.

[0007] In addition to one or more of the features disclosed above, or alternatively, the inner width of the cap cavity is greater than the cap diameter of the test tube, and the distance between the two flanges is less than the cap diameter but greater than the tube body diameter of the test tube.

[0008] In addition to one or more of the features disclosed above, or as an alternative, the clamping module includes at least two of the connecting posts, and at least two holes are correspondingly provided on the top wall of the cap cavity, with each of the connecting posts passing through one of the holes.

[0009] In addition to one or more of the features disclosed above, or as an alternative, each of the connecting posts is fitted with a resilient reset element.

[0010] In addition to one or more of the features disclosed above, or as an alternative, the elastic reset element is a compression spring.

[0011] In addition to one or more of the features disclosed above, or as an alternative, the surface of the cap clamping bar opposite to the flange is a plane or an arcuate surface that matches the shape of the cap.

[0012] In addition to one or more of the features disclosed above, or as an alternative, a positioning part is provided at the junction of the top wall of the cap cavity and the cap inlet / outlet; one end of the positioning part is fixedly connected to the top wall of the cap cavity, and the other end extends away from the cap inlet / outlet.

[0013] In addition to one or more of the features disclosed above, or as an alternative, a pair of grippers are provided on the outer surface of the body, which are symmetrically arranged relative to the clamping handle, and the grippers extend from the outer surface of the body in a direction away from the body.

[0014] In addition to one or more of the features disclosed above, or alternatively, the diameter of at least a portion of the passage near the cap inlet and outlet gradually widens from the inside out, thereby forming a test tube guide surface.

[0015] On the other hand, a test tube automatic feeding system is further disclosed, comprising: a batch tube picker as described in any of the above claims; and a test tube automatic labeling machine having a feeding slot; wherein the batch tube picker is used to pick up and transfer a row of test tubes in batches to the feeding slot of the test tube automatic labeling machine.

[0016] One of the above technical solutions has the following advantages or beneficial effects: through the coordinated operation of the cap cavity and the clamping module, a complete technical path of "cap placement and positioning in the cavity—clamping module fixation—overall transfer and loading" is constructed. Specifically, the elongated U-shaped structure of the cap cavity and the baffle at its bottom, together with the tube body clearance opening, form a "cap-locking without body-locking" limiting mechanism, allowing the caps of the entire row of test tubes to fall naturally into the predetermined position when pushed in, while the tube bodies hang freely without interfering with each other. On this basis, the clamping module utilizes the energy storage and release characteristics of the elastic reset component to drive the cap clamping strip to move towards the baffle by pressing the clamping handle, thereby forming a stable clamping force in the vertical or lateral directions of the cap, so that the posture of the entire row of test tubes is completely locked during the transfer process, which not only avoids the possible tilting, shaking or falling off of individual test tubes, but also eliminates the risk of sample contamination caused by manual contact. When the clamping handle is pressed, the elastic reset element is compressed and stores potential energy. The tube cap clamping strip and the guard together form a reliable clamping interface. After being transferred to the labeling machine's loading slot, the clamping handle is released, and the elastic reset element releases its potential energy, causing the clamping strip to reset. The test tube slides smoothly out along the tube cap inlet and outlet under gravity and falls into the slot. The entire process, from gripping to releasing, can be completed with a single pressing action, making the operation smooth and simple. In addition, by setting a positioning part and a test tube guide surface, the rapid docking of the tube picker with the loading slot and the guiding assistance when the test tubes fall into place are further realized, enabling the batch tube picker to accurately adapt to the working rhythm of the automatic labeling machine. Thus, this embodiment of the application realizes the batch gripping, posture fixation, and precise release of an entire row of test tubes with a purely mechanical structure, optimizing the loading process that originally relied on manual operation of each tube into a batch operation that can be completed in one action, significantly improving loading efficiency and stability, and providing a reliable front-end guarantee for the high-speed and continuous operation of the automatic test tube labeling machine.

Detailed Implementation

[0019] To make the objectives, technical solutions, and beneficial effects of this application clearer, the following detailed description, in conjunction with the accompanying drawings and specific embodiments, further illustrates this application. It should be understood that the specific embodiments described in this specification are merely for explaining this application and are not intended to limit it.

[0020] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0021] This application provides a batch tube picker for an automatic test tube labeling machine. To achieve a single, stable gripping of an entire row of test tubes and ensure the deterministic posture of the test tubes during the gripping process, thereby providing a precise positioning basis for subsequent automated feeding, this embodiment designs the overall structure of the batch tube picker as follows.

[0022] As shown in Figure 1, a batch tube dispenser 1 for an automatic test tube labeling machine includes a long strip-shaped body 11 and a clamping module. The body 11 has a cap cavity 111 for accommodating test tube caps. Specifically, one end of the body 11 is closed, and the other end is open, forming a cap inlet / outlet 111b communicating with the cap cavity 111, through which the test tube cap enters. The bottom of the body 11 is open, forming a tube body clearance opening 111a communicating with the cap cavity 111. This clearance opening 111a is used to accommodate the tube body portion of the test tube 2 during dispensing. The two side edges of the clearance opening 111a are bent inwards to form a pair of opposing baffles 111c. These baffles 111c hook the lower edge of the cap during dispensing, preventing the test tube from detaching from the bottom during transfer.

[0023] Referring to Figures 2 and 3, the clamping module includes a clamping handle 12, a connecting post 13, an elastic reset member 131, and a cap clamping strip 14. One end of the connecting post 13 is fixedly connected to the clamping handle 12, and the other end passes through the top wall of the cap cavity 111 and is fixedly connected to the cap clamping strip 14 located inside the cap cavity 111. The elastic reset member 131 elastically acts on the clamping handle 12, allowing the clamping handle 12 to switch between a clamping state and a released state. In this embodiment, the elastic reset member 131 is a pressure spring, with one end abutting against the clamping handle 12 and the other end abutting against the outer wall of the main body 11.

[0024] When the operator presses the clamping handle 12, the clamping handle 12 compresses the elastic reset member 131, and drives the connecting post 13 and the cap clamping strip 14 to move closer to the stop edge 111c. At this time, if the cap is already housed in the cap cavity 111, the cap will be firmly clamped and fixed between the cap clamping strip 14 and the stop edge 111c. When the clamping handle 12 is released, the elastic potential energy of the elastic reset member 131 is released, driving the clamping handle 12, the connecting post 13, and the cap clamping strip 14 to reset, thereby releasing the clamping of the cap.

[0025] Therefore, this embodiment uses the tube cap clamping strip and the retaining edge as the clamping force-applying and force-receiving components, and uses an elastic reset component to switch the clamping state. This allows the batch tube picker to grab an entire row of test tubes at once with a simple pressing operation. After grabbing, the test tubes are fixed in posture and not easy to shake or fall off, providing a reliable guarantee for accurate docking with the automatic labeling machine.

[0026] Referring to Figures 2 and 3, this embodiment optimizes the dimensions of the cap cavity based on Embodiment 1. To ensure that the test tube cap can smoothly enter the cap cavity, be effectively hooked by the retaining edge in the clamped state, and allow the test tube body to freely pass through the bottom clearance opening, thus balancing the smoothness of tube removal and the reliability of fixation, this embodiment limits the relevant dimensional relationships.

[0027] Specifically, the inner width of the cap cavity 111 is set to be greater than the cap diameter of the test tube 2, thereby ensuring that the cap can slide into the cavity without interference. Simultaneously, the distance between the two flanges 111c is set to be less than the cap diameter but greater than the test tube body diameter. This dimensional design allows the lower edge of the cap to reliably abut against the flanges 111c when the test tube is lifted, while the tube body can freely pass through the tube body clearance opening 111a without obstruction.

[0028] Therefore, by limiting the above-mentioned dimensional relationships, the batch tube picker of this embodiment achieves the positioning effect of "catching the cap but not the body" for the test tubes. This ensures that the cap can be effectively hooked during tube picking, while avoiding unnecessary interference between the tube body and the picker, thus ensuring the smoothness and stability of the batch transfer process.

[0029] Referring again to Figure 2, the connection structure of the clamping module has been optimized in this embodiment. In order to improve the stability and synchronization of the clamping module when driving the movement of the tube cap clamping bar, and to avoid the tube cap clamping bar from deflecting or jamming due to single-point force, thereby ensuring that a uniform and reliable clamping force is applied to the entire row of test tubes, the number and arrangement of the connecting columns have been designed in this embodiment.

[0030] Specifically, the clamping module includes at least two connecting posts 13. Correspondingly, the top wall of the cap cavity 111 has at least two holes, the same number and corresponding in position as the connecting posts 13. One end of each connecting post 13 is fixedly connected to the clamping handle 12, and the other end passes through one of the holes and is fixedly connected to the cap clamping strip 14. Furthermore, to provide a uniform restoring force, each connecting post 13 is fitted with an elastic restoring element 131, such as a pressure spring.

[0031] Therefore, by setting two or more connecting columns and configuring elastic reset elements for each of them, this embodiment enables the clamping handle to drive the cap clamping bar to move smoothly in a straight line through multi-point synchronous transmission when under force, effectively avoiding the torsion problem that may occur in a single-column structure, and significantly improving the reliability of the clamping action and the uniformity of the clamping force.

[0032] This application specifies the particular form of the elastic reset element. In order to achieve the elastic reset function of the clamping handle between the clamping and releasing states in the most economical, reliable and easy-to-install manner, this embodiment selects a pressure spring as the elastic reset element.

[0033] A compression spring is a standard mechanical component with advantages such as simple structure, low cost, stable performance, and linear force-displacement characteristics. When fitted onto a connecting post, with one end acting on the clamping handle and the other end acting on the top wall of the main body, it provides a stable reset driving force for the clamping handle and clear tactile feedback when pressed.

[0034] Therefore, using a pressure spring as an elastic reset component not only simplifies the assembly process and reduces manufacturing costs, but also ensures the working stability and service life of the batch tube pickers under long-term, high-frequency use.

[0035] Referring to Figure 4, the structure of the cap clamping strip 14 has been optimized in this embodiment. In order to obtain a larger contact area and a more stable clamping effect when clamping the cap, and to adapt to caps of different shapes, the surface of the cap clamping strip in contact with the cap has been designed in this embodiment.

[0036] Specifically, the surface of the cap clamping bar 14 opposite to the flange 111c is designed as a flat surface or an arc-shaped surface that matches the shape of the cap. The flat surface is simple, easy to process, and suitable for test tubes with a flat top. The arc-shaped surface can form better surface or line contact with the round or spherical cap, increasing the stability during clamping and preventing the test tube from rolling or tilting in the clamped state.

[0037] Therefore, by selecting a flat or curved surface as the clamping working surface, the batch tube picker of this embodiment can better adapt to test tube caps of different shapes and sizes, expand the product's applicability, and further improve the reliability and stability of clamping.

[0038] Referring to Figures 1 and 2, this embodiment adds a positioning part to the main body 11. In order to quickly and accurately determine the relative position of the tube picker and the feeding slot when placing a row of test tubes into the labeling machine slot, and to avoid the test tubes failing to fall into the slot or colliding due to misalignment, this embodiment provides a positioning part at the junction of the top wall of the cap cavity and the cap inlet / outlet.

[0039] Specifically, a positioning part 115 is provided at the junction of the top wall of the cap cavity 111 and the cap inlet / outlet 111b. One end of the positioning part 115 is fixedly connected to the top wall of the cap cavity 111, and the other end extends away from the cap inlet / outlet 111b. During use, the positioning part 115 can serve as a mechanical reference, cooperating with the corresponding structure of the labeling machine's feeding slot, such as a positioning groove or positioning surface, to achieve rapid and accurate alignment of the tube picker with the feeding slot.

[0040] Therefore, by adding a positioning unit, the batch tube picker in this embodiment achieves physical docking and guidance with the labeling machine's feeding station, greatly simplifying the operator's positioning operation, improving feeding accuracy and efficiency, and enabling the batch tube picker to be better integrated into the automated operation process.

[0041] Furthermore, this embodiment adds a gripper to the main body. To improve the comfort and stability of the operator when holding the tube retriever and performing a series of operations such as tube retrieval, transfer, and release, and to reduce the risk of operational errors caused by hand fatigue or slippage, this embodiment provides a pair of grippers on the outer surface of the main body.

[0042] Specifically, a pair of gripper members 113 are provided on the outer surface of the main body 11, symmetrically arranged relative to the clamping handle 12. The gripper members 113 extend from the outer surface of the main body 11 in a direction away from the main body 11. The gripper member 113 can be plate-shaped, column-shaped, or other ergonomically designed to provide a stable support point and force application point for the operator's fingers, enabling them to more firmly control the tube extractor, especially when pressing the clamping handle and transferring heavy objects.

[0043] Therefore, by setting symmetrical grippers, this embodiment optimizes the human-computer interaction experience of the batch tube picker, making the operation more labor-saving and stable, effectively reducing fatigue caused by long-term operation, and reducing the risk of test tubes falling due to unstable grip.

[0044] Furthermore, referring to Figure 4, the structure of the cap inlet and outlet in this embodiment of the application has been optimized. In order to guide the cap of the test tube to slide smoothly and easily out of the cap cavity when the test tube is placed into the feeding slot of the labeling machine, and to avoid the test tube getting stuck or tipping over due to a sudden change in diameter, this embodiment designs the part of the cap cavity near the inlet and outlet as a gradually widening structure.

[0045] Specifically, the diameter of at least a portion of the channel near the cap inlet / outlet 111b of the cap cavity gradually widens from the inside out, thus forming a test tube guide surface 115. This guide surface 115 can be an inclined slope or a smooth arc. When the operator releases the clamping handle, and the test tube slides out of the cap cavity under gravity or a slight external force, this guide surface can guide the test tube cap to the outside and allow it to fall into the loading trough below in a controllable manner.

[0046] Therefore, by setting a test tube guide surface, this embodiment further improves the smoothness of the feeding process, effectively avoids the test tubes getting stuck or losing their posture at the outlet, and ensures that the entire row of test tubes can fall neatly and stably into the feeding slot of the labeling machine, thus achieving precise feeding.

[0047] This application also provides an automated test tube feeding system. To integrate the advantages of the aforementioned batch tube feeder into a complete automated workflow and address the issues of low efficiency and poor stability in the feeding process in existing technologies, this embodiment constructs a system comprising a batch tube feeder and an automated test tube labeling machine.

[0048] Specifically, an automatic test tube feeding system includes a batch tube picker 1 as described in any of the foregoing embodiments and an automatic test tube labeling machine. The automatic test tube labeling machine has a feeding slot. The batch tube picker 1 is used to pick up entire rows of test tubes in batches and accurately transfer them to the feeding slot of the automatic test tube labeling machine. The feeding slot may be equipped with a positioning structure that cooperates with the positioning part 115 on the tube picker to achieve rapid docking.

[0049] During operation, the operator first uses the batch tube picker 1 to grab a whole row of test tubes from the foam base at once. Then, the tube picker holding the test tubes is transferred to the top of the labeling machine, where it is quickly aligned with the feeding slot by the positioning part. Finally, the clamping handle is released, and the test tubes fall neatly into the feeding slot under the guidance of the guide surface, completing the feeding process. The labeling machine then automatically labels the test tubes that have fallen into the slot.

[0050] Therefore, this embodiment organically combines the batch tube picker with the automatic labeling machine to form a highly efficient and stable feeding system. This system overcomes the shortcomings of manual single-tube feeding or feeding with simple tools, which are characterized by low efficiency, easy errors, and uncontrollable posture. It realizes the "batch, stable, and accurate" transfer of test tubes from the storage carrier to the labeling station, significantly improving the overall operating efficiency and automation level of the automatic test tube labeling machine.

[0051] This application also describes in detail the operation method of batch tube picking and placing using the batch tube picker 1 described in any of the foregoing embodiments. In order to fully disclose the technical solution of the present invention, so that those skilled in the art can clearly and accurately understand and implement the entire process of batch tube picking, thereby giving full play to the advantages of the batch tube picker in improving material feeding efficiency and stability, the operation steps are described in detail below.

[0052] As shown in Figures 1 and 2, the operation method of this batch tube picker 1 includes the following steps: (1) Preparation and tube picking steps: The operator first holds the batch tube picker 1 with one or both hands. In the initial state, the clamping handle 12 is in the released state under the action of the elastic reset member 131, that is, a large gap is maintained between the tube cap clamping bar 14 and the stop edge 111c.

[0053] The operator aligns the cap inlet / outlet 111b of the batch tube picker 1 with the caps of one row of test tubes 2 in a foam test tube base typically arranged in a 10×10 pattern. Then, the caps of the entire row of test tubes are pushed horizontally into the cap cavity 111. During this process, the tube body of the test tube 2 hangs naturally through the tube body clearance opening 111a, while the cap is completely contained within the cap cavity 111, with its lower edge positioned above the retaining edge 111c.

[0054] (2) Clamping Step: The operator presses the clamping handle 12 with their palm or fingers, causing the clamping handle 12 to move towards the main body 11 against the elastic force of the elastic reset member 131. The pressing force is transmitted to the cap clamping bar 14 through the connecting column 13, driving the cap clamping bar 14 to move towards the side flange 111c until the caps of the entire row of test tubes are firmly clamped and fixed between the cap clamping bar 14 and the side flange 111c.

[0055] In this clamped state, because the baffle 111c hooks the lower edge of the cap from below, and the cap clamping bar 14 presses the cap from above or the side, the posture of the entire row of test tubes 2 is completely locked, and they cannot move up and down or sway left and right.

[0056] (3) Transfer Step: The operator keeps pressing the clamping handle 12 to keep the test tubes 2 clamped. Then, the operator lifts the batch tube extractor 1 upwards. Because the lower edge of the tube cap is blocked by the retaining edge 111c, the entire row of test tubes 2 is pulled out of the insertion hole of the foam base by the tube extractor and detaches from the original carrier together with the tube extractor.

[0057] The operator keeps the tube picker clamped and transfers the batch tube picker 1 along with the entire row of test tubes 2 to the top of the loading trough of the automatic test tube labeling machine. During this process, if the tube picker is equipped with a gripper 113, the operator can place their fingers on the gripper 113 for a more stable and effortless grip.

[0058] (4) Alignment and Release Steps: After transferring to the target position, the operator adjusts the posture of the batch tube picker 1 so that the tube body of the test tube 2 is aligned with the feeding slot on the labeling machine. If the tube picker is equipped with a positioning part 115, the operator can use the positioning part 115 to quickly and accurately dock with the corresponding positioning structure on the feeding slot, such as the positioning groove or positioning surface, to ensure that the landing position of the test tube 2 is accurate.

[0059] Once the batch tube picker 1 is accurately positioned, the operator releases the clamping handle 12. At this time, the elastic reset component 131 releases its elastic potential energy, driving the clamping handle 12, connecting column 13, and cap clamping strip 14 to reset. The clamping force between the cap clamping strip 14 and the cap disappears, and the test tubes 2 fall naturally under gravity. If there is a test tube guide surface 115 at the cap inlet / outlet 111b, the cap of the test tube 2 will slide smoothly out of the cap cavity 111 along the guide surface, and the entire row of test tubes 2 will fall neatly and stably into the bottom of the feeding trough.

[0060] (5) Reset Step: The operator removes the batch tube picker 1 to complete a batch loading operation. At this time, the elastic reset component 131 of the batch tube picker 1 has restored the clamping handle 12 and the tube cap clamping strip 14 to the initial release state, which can be used for the next tube picking operation.

[0061] Therefore, through the above steps, operators can use this batch tube picker to perform a continuous operation of "push-press-lift-transfer-align-release," completing the batch grabbing and precise loading of an entire row of test tubes in one go. This method is simple to operate, has continuous actions, and is highly reliable. It effectively replaces the cumbersome process of traditional manual single-tube loading or loading with simple tools, significantly improving the efficiency and stability of the loading stage of the automatic test tube labeling machine, and reducing the labor intensity and operational error rate of operators.

[0062] The above steps are provided only to help understand the method, structure, and core ideas of this application. Those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims.
