Description

Technical Field

[0001] This utility model relates to the field of sample tube labeling technology, and more specifically, to an automatic sample tube labeling device. Background Technology

[0002] In the medical field, affixing barcode labels to sample tubes is not only to meet the requirements of laws and regulations, but also a key measure to ensure patient safety and improve the quality and efficiency of medical services. Therefore, barcode affixing is very important for the accuracy, integrity and readability of samples.

[0003] The currently disclosed technical solutions for automatic labeling equipment have at least the following problems:

[0004] 1. Single-station processing bottleneck: Traditional equipment adopts a single labeling station architecture, which cannot realize multi-process collaborative operation. Sample tubes need to flow sequentially between tube supply, labeling, buffering, output and barcode reading. The high coupling between processes and the existence of mechanical waiting time result in limited system throughput.

[0005] 2. Defects in the split-type labeling design: Although some multi-station improvement schemes achieve parallel labeling, they often use independent labeling stations for secondary processing. This step-by-step operation leads to:

[0006] 2.1 Risk of label bonding failure: Delay in the label pressing process can lead to insufficient curing of the adhesive, resulting in labels falling off or becoming missing.

[0007] 2.2 Fragmented Inspection Process: Barcode reading needs to be performed separately after labeling, which cannot achieve real-time online verification. This requires the addition of a re-inspection station, which reduces the production line cycle time and the labeling success rate.

[0008] Therefore, existing equipment has structural defects in terms of parallel processing capability, process integration and quality control. How to improve the labeling efficiency and quality of sample tubes is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0009] In view of this, the purpose of this utility model is to provide an automatic labeling device for sample tubes, which can improve the labeling efficiency and quality of sample tubes.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] An automatic labeling device for sample tubes, comprising:

[0012] The turntable mechanism includes multiple workstations, a turntable, and a first drive assembly. The multiple workstations are arranged around the rotation direction of the turntable. The turntable is provided with multiple tube sleeves corresponding to the multiple workstations. The tube sleeves allow sample tubes to be placed vertically and can rotate with the turntable to pass through the multiple workstations in sequence. One of the workstations is a labeling workstation.

[0013] The labeling mechanism includes a rotating shaft group, a fixed shaft group, a second drive assembly, and a third drive assembly. The second drive assembly connects the rotating shaft group and the fixed shaft group, which are both vertically arranged, to drive them to move towards or away from each other around the labeling station. The third drive assembly connects to the rotating shaft group to drive the rotating shaft group to rotate.

[0014] A label printer, located adjacent to the labeling station, is used to print labels and peel the labels off to a position between the sample tube and the fixed shaft assembly;

[0020] Preferably, the turntable mechanism further includes an origin sensor facing the placement station, used to detect the origin position of the turntable and transmit the signal to the control device.

[0021] Preferably, the labeling mechanism further includes a bracket, a guide shaft, a rotating shaft bracket, and a fixed shaft bracket. The guide shaft is disposed on the bracket and is horizontally located above the labeling station. The rotating shaft bracket and the fixed shaft bracket are slidably sleeved on the guide shaft. One side of the rotating shaft bracket is rotatably connected to the rotating shaft assembly, and one side of the fixed shaft bracket is fixedly connected to the fixed shaft assembly.

[0022] Preferably, compression springs are fitted at both ends of the guide shaft, and the two compression springs are respectively connected to the opposite ends of the rotating shaft bracket and the fixed shaft bracket. Abutment blocks are provided on the other side of both the rotating shaft bracket and the fixed shaft bracket.

[0023] The second drive assembly includes a second driver, a first transmission assembly, and a support plate. The second driver is disposed on the bracket and located on the side of the guide shaft facing away from the fixed shaft assembly. The second driver is connected to the support plate through the first transmission assembly to drive the support plate to rotate.

[0024] When the two edges of the support plate along its length abut against the two abutment blocks respectively, the rotating shaft support and the fixed shaft support are in their maximum open state.

[0025] When the two edges of the support plate in the width direction abut against the two abutment blocks respectively, the rotating shaft support and the fixed shaft support are in a closed state.

[0026] Preferably, the rotating shaft assembly includes two rotating shafts, which are arranged along an extension direction perpendicular to the guide shaft and with a gap between them; the fixed shaft assembly includes one fixed shaft, which is positioned directly opposite the gap.

[0027] The third drive assembly includes a third driver and a second transmission assembly. The third driver is mounted on the bracket and located on the side of the rotating shaft bracket facing away from the fixed shaft bracket. The third driver connects the two rotating shafts through the second transmission assembly to synchronously drive the two rotating shafts to rotate.

[0028] Preferably, the labeling mechanism further includes a third sensor and a fourth sensor, both mounted on the bracket;

[0029] The third sensor is located directly above the maximum opening position of the fixed shaft bracket, and is used to detect whether the fixed shaft bracket and the rotating shaft bracket are fully opened, and transmit the signal to the control device.

[0030] The fourth sensor is located directly above the closed position of the fixed shaft bracket and is used to detect whether the fixed shaft bracket and the rotating shaft bracket are closed in place, and transmit the signal to the control device.

[0031] Preferably, the device further includes a slide drawer assembly, which includes a drawer body and a slide assembly. The drawer body is movably disposed in the extending direction of the slide assembly, and the drawer body and the slide assembly are detachably connected.

[0032] The turntable mechanism, the labeling mechanism, the label printer, and the barcode scanner are all located on the drawer body.

[0033] Preferably, the drawer body includes a main board, a pull plate, and two sliding plates. The pull plate is located at one end of the main board along its length, and the two sliding plates are located on both sides of the main board along its width.

[0034] The slide rail assembly includes two slide rails and a frame. The two slide rails are respectively located on the two side plates in the width direction of the frame and are detachably and slidably connected to the two slide plates.

[0035] Preferably, a sleeve is connected to the bottom end of the main board away from the pull plate, and an electromagnet suction plate and an electromagnet suction plate are connected to the bottom end of the main board adjacent to the pull plate.

[0036] One end of the skeleton along its length is provided with a positioning shaft that is compatible with the sleeve for insertion, and the other end of the skeleton along its length is provided with an electromagnet and a positioning sensor. When the electromagnet suction plate is attracted to the electromagnet, the electromagnet suction plate triggers the positioning sensor to send a positioning signal to the control device.

[0037] The automatic labeling device for sample tubes provided by this utility model allows for manual or robotic placement of a sample tube vertically into the corresponding sleeve at a turntable station (e.g., the placement station). A first drive component drives the turntable to rotate counter-clockwise, moving the sample tube from the previous station to the next (e.g., from the placement station to the buffer station). Simultaneously, a manual or robotic hand places the next sample tube into the corresponding sleeve at the previous station on the turntable. The first drive component then drives the turntable to rotate counter-clockwise again until the sample tube reaches the labeling station. At this point, the rotating shaft assembly and the fixed shaft assembly are opened by the second drive component. The label printer then prints the label and peels it off between the sample tube and the fixed shaft assembly. Afterward, a third drive component drives the rotating shaft assembly to rotate, and the second drive component... The component drives the rotating shaft group and the fixed shaft group to move towards each other around the labeling station, so that they come together and clamp the sample tube, thereby attaching the label to the sample tube. The rotating shaft group drives the sample tube to rotate, and the barcode scanner continuously scans the sample tube until it is successfully read. At this time, the label has been completely attached along the circumference of the sample tube. The third drive component stops driving the rotating shaft group to rotate, and the sample tube stops rotating. Then, the second drive component drives the rotating shaft group and the fixed shaft group to move away from each other around the labeling station. After the rotating shaft group and the fixed shaft group are in the open state, the first drive component drives the turntable to rotate counterclockwise again and rotates the sample tube to the next station (e.g., the picking station) to wait for manual or robotic arm to pick it up. At the same time, the next sample tube will follow the turntable to rotate to the labeling station and repeat the above labeling process.

[0038] In summary, the automatic labeling device for sample tubes provided in this application has the following beneficial effects:

[0039] (1) The turntable has multiple stations, which can realize continuous supply of sample tubes, sample tube buffering, automatic labeling and sample tube picking, thereby improving the labeling efficiency of sample tubes.

[0040] (2) By using a fixed shaft group and a rotating shaft group to clamp the sample tube for labeling, the label paper can be completely attached along the circumference of the sample tube by rotating the sample tube, avoiding problems such as label wrinkles, label skew, and label curling, thus improving the labeling quality of the sample tube.

[0041] (3) The rotating shaft assembly enters the rotating state before clamping the sample tube, which can not only prevent the rotating shaft assembly from sticking to the label and improve the labeling quality of the sample tube, but also improve the labeling efficiency of the sample tube.

[0042] (4) During the process of clamping the sample tube with the fixed shaft group and the rotating shaft group, the barcode scanner continuously scans the sample tube. When the barcode scanner successfully reads the code, it means that the label is completely attached to the sample tube. There is no need to enter the next station for scanning and detection, thereby improving the labeling efficiency of the sample tube. Attached Figure Description

[0058] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0059] The core of this invention is to provide an automatic labeling device for sample tubes, which can improve the labeling efficiency and quality of sample tubes.

[0060] It should be noted that in this embodiment, the orientation or positional relationship indicated by "up", "down", "front", "back", "left", "right", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing this application and simplifying the description, and is not intended to 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, it should not be construed as a limitation on this application.

[0061] Please refer to Figure 1 This application provides an automatic labeling device for sample tubes, including a turntable mechanism 1, a labeling mechanism 2, a label printer 3, a barcode scanner 4, and a control device.

[0062] The turntable mechanism 1 includes multiple workstations, a turntable 11, and a first drive assembly. The multiple workstations are arranged around the rotation direction of the turntable 11. The turntable 11 is provided with multiple tube sleeves 12 that correspond one-to-one with the multiple workstations. The tube sleeves 12 allow the sample tubes to be placed vertically and can rotate with the turntable 11 to pass through the multiple workstations in sequence. One of the workstations is the labeling workstation C. The first drive assembly is connected to the turntable 11 to drive the turntable 11 to rotate.

[0063] It should be noted that a workstation refers to a specific position where the equipment completes a certain process, and therefore, the workstation remains fixed. In this application, multiple workstations can be divided into placement workstation A, labeling workstation C, and picking workstation D according to the type of process. Placement workstation A is used to specify the position where a person or robot places the sample tube, labeling workstation C is used to realize the automatic labeling of the sample tube, and picking workstation D is used to specify the position where a person or robot picks up the labeled sample tube. The above-mentioned placement workstation A, labeling workstation C, and picking workstation D are arranged in sequence around the rotation direction of turntable 11. In this way, the sample tube can sequentially pass through placement workstation A, labeling workstation C, and picking workstation D to perform processes such as supply, automatic labeling, and sample tube picking.

[0064] Preferably, the multiple workstations may also include at least one buffer workstation B, which is located between the placement workstation A and the labeling workstation C. Buffer workstation B is used as a position for placing the sample tubes to be labeled, which can reduce the time it takes for the sample tubes to rotate to the labeling workstation C, thereby reducing the downtime of the equipment during labeling and thus improving the labeling efficiency of the sample tubes.

[0065] In addition, such as Figure 2 As shown, the turntable 11 is provided with multiple tube sleeves 12, and the multiple tube sleeves 12 are arranged in a one-to-one correspondence with multiple workstations. That is to say, when the turntable 11 is at the zero point position (i.e., the initial position), each workstation has a tube sleeve 12. In this way, the sample tube on each tube sleeve 12 can rotate with the turntable 11 to pass through multiple workstations in sequence. The tube sleeve 12 is used to vertically fit the sample tube, and the tube sleeve 12 restricts the radial movement of the sample tube to prevent the sample tube from tipping over. The turntable 11 restricts the downward movement of the sample tube to support the sample tube.

[0066] The labeling mechanism 2 includes a rotating shaft group, a fixed shaft group, a second drive assembly, and a third drive assembly. The second drive assembly connects the rotating shaft group and the fixed shaft group, which are both vertically arranged, to drive them to move towards or away from each other around the labeling station C. The third drive assembly connects to the rotating shaft group to drive the rotating shaft group to rotate.

[0067] Label printer 3 is located adjacent to labeling station C and is used to print labels and peel them off to the position between the sample tube and the fixed shaft assembly. This position is related to the label ejection port position of label printer 3, and the height of the label ejection port of label printer 3 can be adjusted according to the actual labeling position requirements of the sample tube. It should be noted that the specific structure of label printer 3 can be found in existing technology, but it is not the focus of this application and will not be described in detail here.

[0068] The barcode scanner 4 is positioned towards the labeling station C and is used to scan the labels on the sample tubes. In other words, the scanning head of the barcode scanner 4 is aligned with the labeling station C to scan the sample tubes located at the labeling station C, thereby determining whether the label is completely affixed to the sample tube, i.e., whether the labeling of the sample tube is complete. It should be noted that the specific structure of the barcode scanner 4 can be found in existing technology, but it is not the focus of this application and will not be described in detail here.

[0069] The control device is connected to the first drive assembly, the second drive assembly, the third drive assembly, the label printer 3, and the barcode scanner 4.

[0070] It should be noted that a control device is a device used to receive signals, make judgments, and execute instructions. The control device controls various components in a coordinated manner to achieve automated labeling of the equipment.

[0071] The following example uses multiple workstations, including equally spaced placement workstation A, buffer workstation B, labeling workstation C, and pickup workstation D, to illustrate the labeling process of the automatic labeling equipment for sample tubes provided in the above embodiment. The specific process is as follows:

[0072] First, either manually or with a robotic arm, the first sample tube can be placed onto tube sleeve #1 at placement station A. The first drive component drives turntable 11 to rotate 90 degrees counterclockwise, switching tube sleeve #1 to buffer station B. At this time, tube sleeve #2 is switched to placement station A. The manual or robotic arm can then place the second sample tube onto tube sleeve #2 at placement station A. Simultaneously, the second drive component drives the rotating shaft group and the fixed shaft group to move in opposite directions around placement station A, keeping them in an open state to avoid interfering with the rotation of tube sleeve #1 to placement station A. Then, the first drive component drives turntable 11 to rotate 90 degrees counterclockwise again, switching tube sleeve #1 to placement station A. At this time, tube sleeve #2 is switched to buffer station B, and tube sleeve #3 is switched to placement station A. The manual or robotic arm can then place the third sample tube onto tube sleeve #3 at placement station A. Simultaneously, label printer 3 prints a label and peels it off onto the sample tube on tube sleeve #1. After fixing the position between the fixed shaft groups, the third drive component drives the rotating shaft group to enter the rotation state. The second drive component drives the rotating shaft group and the fixed shaft group to move towards each other around the labeling station C, so that they come together and clamp the sample tube, thereby attaching the label to the sample tube. The rotating shaft group drives the sample tube to rotate, and at the same time, the barcode scanner 4 continuously scans the sample tube until the reading is successful. At this time, the label has been completely attached along the circumference of the sample tube. The third drive component stops driving the rotating shaft group to rotate, and the sample tube stops rotating. Then, the second drive component drives the rotating shaft group and the fixed shaft group to move away from each other around the labeling station C. After the rotating shaft group and the fixed shaft group are in the open state, the first drive component drives the turntable 11 to rotate 90 degrees counterclockwise again. The tube sleeve No. 1 is switched to the picking station D, waiting for manual or robotic arm to pick it up. At the same time, the tube sleeve No. 2 is switched to the labeling station C, the tube sleeve No. 3 is switched to the buffer station B, and the tube sleeve No. 4 is switched to the placement station A, starting a new round of the above labeling process.

[0073] Therefore, the automatic labeling equipment for sample tubes provided in the above embodiments has the following advantages:

[0074] First, the turntable 11 has multiple workstations, which can realize continuous supply of sample tubes, sample tube buffering, automatic labeling and sample tube picking, thereby improving the labeling efficiency of sample tubes.

[0075] Secondly, by using a fixed shaft group and a rotating shaft group to clamp the sample tube for labeling, the label paper can be completely attached along the circumference of the sample tube by rotating the sample tube, avoiding problems such as label wrinkles, label skew, and label curling, thus improving the labeling quality of the sample tube.

[0076] Third, the rotating shaft assembly enters a rotating state before clamping the sample tube, which not only prevents the rotating shaft assembly from sticking to the label and improves the labeling quality of the sample tube, but also improves the labeling efficiency of the sample tube.

[0077] Fourth, during the process of clamping the sample tube with the fixed shaft group and the rotating shaft group and labeling it, the barcode scanner 4 continuously scans the sample tube at the same time. When the barcode scanner 4 successfully reads the code, it means that the label is completely attached to the sample tube. There is no need to enter the next station for scanning and detection, thereby improving the labeling efficiency of the sample tube.

[0078] Based on the above embodiments, as a preferred embodiment, the turntable mechanism 1 further includes a mounting frame 14, on which a first drive component is mounted and its shaft is connected to the turntable 11.

[0079] Specifically, the first drive component adopts a first driver 13, which is mounted on the mounting bracket 14, and the rotating shaft of the first driver 13 is connected to the turntable 11 to support the turntable 11 to rotate stably. In addition, the first driver 13 is preferably a stepper motor, which precisely controls the angular displacement by the number of pulses, thereby enabling precise control of the single rotation angle of the turntable 11 (e.g., 90 degrees).

[0080] It should be noted that the multiple workstations include a placement workstation A, a buffer workstation B, a labeling workstation C, and a pickup workstation D. These four workstations are arranged at equal intervals around the rotation direction of the turntable 11. Even if the angle between two adjacent workstations is 90 degrees, this workstation setup not only reduces the downtime during labeling and improves the labeling efficiency of the sample tubes, but also ensures that each workstation has a tube sleeve 12 when the first driver 13 continuously and repeatedly drives the turntable 11 to rotate 90 degrees. This allows for the parallel completion of continuous supply, sample tube buffering, automatic labeling, and sample tube pickup processes across multiple workstations. The following embodiments will use this workstation setup as an example for explanation.

[0081] Based on the above embodiments, as a further preferred option, please refer to... Figure 2 The turntable mechanism 1 also includes a first sensor 16 facing the placement station A. The first sensor 16 is used to detect whether the tube sleeve 12 located at the placement station A has a sample tube and transmits the signal to the control device.

[0082] Therefore, for example, when any of tube sleeves 1-4 12 are switched to placement station A, if the first sensor 16 does not detect a sample tube, it sends a sample tube placement command to the control device. The control device can then control the robotic arm to place the sample tube onto the tube sleeve 12, or it can emit an audible sound to remind the operator to place the sample tube onto the tube sleeve 12. If the first sensor 16 detects a sample tube, it sends a sample tube positioning command to the control device. The control device then controls the first driver 13 to drive the turntable 11 to rotate 90 degrees counterclockwise, moving the sample tube to buffer station B. Thus, the first sensor 16 can continuously and automatically supply sample tubes, thereby reducing downtime during labeling and improving labeling efficiency.

[0083] For specific installation instructions for the first sensor 16, please refer to [link / reference]. Figure 2 The turntable mechanism 1 also includes a first sensor mounting bracket 15, which is set facing the placement station A. The first sensor 16 is set on the first sensor mounting bracket 15 and is at the same height as the tube sleeve 12, so that it can more sensitively detect whether the tube sleeve 12 at the placement station A has a sample tube.

[0084] Based on the above embodiments, as a further preferred option, please refer to... Figure 2 The turntable mechanism 1 also includes a second sensor 19 facing the pickup station D. The second sensor 19 is used to detect whether the tube sleeve 12 located at the pickup station D has a sample tube and transmits the signal to the control device.

[0085] Thus, for example, after tube #1 is automatically labeled at labeling station C, it rotates 90 degrees with turntable 11 to pick-up station D. At this time, the second sensor 19 detects the sample tube and sends a pick-up command to the control device. The control device can then control the robotic arm to move to pick-up station D to remove the sample tube, or it can emit an audible sound to remind a person to remove the sample tube from pick-up station D. Therefore, the second sensor 19 can continuously and automatically pick up labeled sample tubes, thereby reducing the downtime during labeling and improving the labeling efficiency of sample tubes.

[0086] For specific installation instructions for the second sensor 19, please refer to [link / reference needed]. Figure 2 The turntable mechanism 1 also includes a second sensor mounting bracket 18, which is directly opposite the pickup position. The second sensor 19 is mounted on the second sensor mounting bracket 18 and is at the same height as the tube sleeve 12, so that it can more sensitively detect whether the tube sleeve 12 of the pickup station D has a sample tube.

[0087] Based on the above embodiments, as a further preferred option, please refer to... Figure 2The turntable mechanism 1 also includes an origin sensor 17 facing the workstation A, which is used to detect the origin position of the turntable 11 and transmit the signal to the control device.

[0088] The origin sensor 17 is mounted on the first sensor mounting bracket 15 and is also set facing the placement station A. Therefore, the tube sleeve 12 initially located on the turntable 11 at the placement station A can be used as the origin position of the turntable 11. For example, a sensing block can be set at the position of tube sleeve No. 1 on the turntable 11. When the turntable 11 rotates, the origin sensor 17 can scan the sensing block on the turntable 11 in real time and transmit the signal to the control device. This allows the control device to accurately control the movement trajectory of the turntable 11 based on the obtained origin position, ensuring that the turntable 11 can return to the predetermined starting position each time it starts, that is, the tube sleeve No. 1 is rotated back to the placement station A, thereby ensuring that the movement trajectory of the turntable 11 is accurate and stable.

[0089] Based on the above embodiments, as a further preferred option, please refer to... Figure 3 The labeling mechanism 2 also includes a support frame, which includes an inverted L-shaped column 21 and a crossbeam 22. The column 21 is located on one side of the labeling station C, and the bottom end of the vertical plate of the column 21 is provided with a column support 23 for stable support of the column 21. The horizontal plate of the column 21 is connected to the horizontal crossbeam 22, which spans above the labeling station C. Both the rotating shaft assembly and the fixed shaft assembly can be movably mounted on the crossbeam 22, thereby enabling the rotating shaft assembly and the fixed shaft assembly to move towards or away from each other with the labeling station C as the center.

[0090] Based on the above embodiments, and considering the specific arrangement of the rotating shaft assembly and the fixed shaft assembly, please refer to the following as a further preferred embodiment. Figure 3 The labeling mechanism 2 also includes a guide shaft 217, a rotating shaft bracket 216, and a fixed shaft bracket 215. The guide shaft 217 is mounted on the bracket and is horizontally located above the labeling station C. The rotating shaft bracket 216 and the fixed shaft bracket 215 are slidably mounted on the guide shaft 217. One side of the rotating shaft bracket 216 is rotatably connected to a rotating shaft assembly, and one side of the fixed shaft bracket 215 is fixedly connected to a fixed shaft assembly.

[0091] Specifically, the guide shaft 217 is fixed on the horizontal plate of the column 21 and is horizontally located above the labeling station C. Both the rotating shaft bracket 216 and the fixed shaft bracket 215 are provided with through holes that are slidably adapted to the guide shaft 217. The front side of the rotating shaft bracket 216 and the labeling station C are aligned in the front-to-back direction. The front side of the rotating shaft bracket 216 is rotatably connected to a vertical rotating shaft assembly. The front side of the fixed shaft bracket 215 and the labeling station C are aligned in the front-to-back direction. The front side of the fixed shaft bracket 215 is fixedly connected to a vertical fixed shaft assembly.

[0092] Therefore, the opening or closing motion of the rotating shaft support 216 and the fixed shaft support 215 along the guide shaft 217 can realize the movement of the rotating shaft 27 and the fixed shaft 28 towards or away from each other with the labeling station C as the center. The sliding fit between the rotating shaft support 216, the fixed shaft support 215 and the guide shaft 217 can guide the rotating shaft 27 and the fixed shaft 28 to move smoothly on the specified trajectory, thereby ensuring that the rotating shaft 27 and the fixed shaft 28 can clamp or release the sample tube of the labeling station C.

[0093] Furthermore, please refer to Figure 3 The labeling mechanism 2 also includes a guide rail 2115, which is horizontally mounted on the crossbeam 22 and located below the guide shaft 217. The rotating shaft bracket 216 and the fixed shaft bracket 215 are also slidably mounted on the guide rail 2115, so that the guide rail 2115 and the guide shaft 217 work together to guide the rotating shaft bracket 216 and the fixed shaft bracket 215 to slide, thereby more firmly supporting the smooth sliding of the rotating shaft bracket 216 and the fixed shaft bracket 215.

[0094] Based on the above embodiments, and considering the specific methods for opening or closing the rotating shaft assembly and the fixed shaft assembly, as a further preferred option, please refer to... Figure 3 Compression springs 2112 are fitted at both ends of the guide shaft 217. The two compression springs 2112 are respectively connected to the opposite ends of the rotating shaft bracket 216 and the fixed shaft bracket 215. Abutment blocks 218 are provided on the other side of the rotating shaft bracket 216 and the fixed shaft bracket 215. The second drive assembly includes a second driver 29, a first transmission assembly and a support plate 214. The second driver 29 is located on the bracket and on the side of the guide shaft 217 opposite to the fixed shaft assembly. The second driver 29 is connected to the support plate 214 through the first transmission assembly to drive the support plate 214 to rotate. When the two edges of the support plate 214 in the length direction abut against the two abutment blocks 218 respectively, the rotating shaft bracket 216 and the fixed shaft bracket 215 are in the maximum open state. When the two edges of the support plate 214 in the width direction abut against the two abutment blocks 218 respectively, the rotating shaft bracket 216 and the fixed shaft bracket 215 are in the closed state.

[0095] Specifically, a first compression spring 2112 is sleeved on the left end of the guide shaft 217 and connected to the left end of the rotating shaft bracket 216. A second compression spring 2112 is sleeved on the right end of the guide shaft 217 and connected to the right end of the fixed shaft bracket 215. An abutment block 218 is provided on the rear side of both the rotating shaft bracket 216 and the fixed shaft bracket 215.

[0096] Additionally, please refer to Figure 3The bracket also includes a first mounting plate 24. The end of the horizontal plate of the column 21 away from its vertical plate is vertically connected to the first mounting plate 24. The second driver 29 is fixed on the first mounting plate 24. Since the fixed shaft assembly and the rotating shaft assembly are both located in front of the guide shaft 217, the second driver 29 is located behind the guide shaft 217 to avoid interfering with the opening or closing of the fixed shaft assembly and the rotating shaft assembly. The second driver 29 is connected to the support plate 214 through the first transmission assembly, so that the second driver 29 can drive the support plate 214 to rotate. The support plate 214 is located between the two abutment blocks 218 and is set opposite to the labeling station C. Thus, when the support plate 214 rotates to the point where its two edges in the length direction abut against the two abutment blocks 218 respectively, the rotating shaft bracket 216 and the fixed shaft bracket 215 are in the maximum open state. Correspondingly, the rotating shaft 27 and the fixed shaft 28 are in the maximum open state. At this time, the two compression springs 2112 are compressed, such as Figure 4 and Figure 5 As shown; when the support plate 214 rotates to the point where its two edges in the width direction abut against the two abutment blocks 218 respectively, the rotating shaft support 216 and the fixed shaft support 215 close. Correspondingly, the rotating shaft 27 and the fixed shaft 28 are in the minimum closed state. It should be noted that during the closing process of the rotating shaft support 216 and the fixed shaft support 215, the elastic restoring force of the two compression springs 2112 drives the rotating shaft support 216 and the fixed shaft support 215 to close.

[0097] Therefore, the above structure is used to open or close the rotating shaft 27 and the fixed shaft 28. That is, only one drive component is used to drive the opening, and the elastic restoring force of the compression spring 2112 is used to drive the closing. This method has a simple structure and saves costs.

[0098] For specific details regarding the configuration of the first transmission assembly, please refer to [link / reference]. Figure 3 , Figure 4 and Figure 6 The first transmission assembly includes a first driving pulley 210, a first driven pulley 211, and a first synchronous belt 212. The first driving pulley 210 is sleeved on the rotating shaft of the first driver 13. The first driven pulley 211 is fixed on the first mounting plate 24 and is positioned opposite to the labeling station C. The first synchronous belt 212 connects the first driving pulley 210 and the first driven pulley 211. A connecting shaft 213 is provided on one side of the support plate 214 in the thickness direction, and the connecting shaft 213 is coaxially connected to the first driven pulley 211. Thus, the first driver 13 drives the first driving pulley 210 to rotate, the first driving pulley 210 drives the first driven pulley 211 to rotate via the first synchronous belt 212, and the first driven pulley 211 then drives the support plate 214 to rotate via the connecting shaft 213, thereby transmitting the driving force of the first driver 13 to the support plate 214 to drive the support plate 214 to rotate. It should be noted that the first transmission assembly uses a synchronous belt pulley set for driving force transmission, which provides high transmission accuracy, smooth transmission, and high efficiency.

[0099] Based on the above embodiments, as a further preferred option, please refer to... Figure 3 The rotating shaft assembly includes two rotating shafts 27, which are arranged along the extension direction perpendicular to the guide shaft 217 and with a gap between them. The fixed shaft assembly includes a fixed shaft 28, which is positioned directly opposite the gap.

[0100] Understandably, the two rotating shafts 27 are arranged side by side in the front-to-back direction, and a fixed shaft 28 is set directly opposite the gap between the two rotating shafts 27. In this way, on the one hand, the two rotating shafts 27 and the fixed shaft 28 can be arranged in a triangle, which can clamp the sample tube more firmly. On the other hand, the two rotating shafts 27 work together to drive the sample tube to rotate, which can rotate the sample tube smoothly and quickly, thereby improving the labeling efficiency of the sample tube.

[0101] Based on the above embodiments, and considering the specific way of realizing the rotation of the rotating shaft assembly, as a further preferred embodiment, the third drive assembly includes a third driver 219 and a second transmission assembly. The third driver 219 is mounted on the bracket and located on the side of the rotating shaft bracket 216 facing away from the fixed shaft bracket 215. The third driver 219 connects the two rotating shafts 27 through the second transmission assembly to synchronously drive the two rotating shafts 27 to rotate.

[0102] Specifically, the bracket also includes a second mounting plate 25, which is connected to the first mounting plate 24 and is opposite to the horizontal plate of the column 21. A crossbeam 22 is connected between the second mounting plate 25 and the horizontal plate. A third driver 219 is fixed on the second mounting plate 25. The third driver 219 is connected to two rotating shafts 27 through the second transmission assembly, so that it can synchronously drive the two rotating shafts 27 to rotate.

[0103] For specific details regarding the configuration of the second transmission assembly, please refer to [link / reference]. Figure 3 and Figure 5 The second transmission assembly includes three rollers 2111 and a second timing belt 2110. The first roller 2111 is mounted on the shaft of the third driver 219. Two fixed shafts 2117 are arranged sequentially from front to back on the front side of the rotating shaft support 216. The bottom of each fixed shaft 2117 is fitted with a second roller 2111 and a third roller 2111, respectively. The second roller 2111 is coaxially connected to one rotating shaft 27, and the third roller 2111 is coaxially connected to another rotating shaft 27. The second timing belt 2110 connects the three rollers 2111. Thus, the rotation of the shaft of the third driver 219 can synchronously drive the rotation of the two rotating shafts 27 via the timing belt.

[0104] Based on the above embodiments, as a further preferred option, please refer to... Figure 3The labeling mechanism 2 also includes a third sensor 2113 and a fourth sensor 2114, both mounted on the bracket. The third sensor 2113 is directly above the maximum opening position of the fixed shaft bracket 215 and is used to detect whether the fixed shaft bracket 215 and the rotating shaft bracket 216 are fully open and transmit the signal to the control device. The fourth sensor 2114 is directly above the closed position of the fixed shaft bracket 215 and is used to detect whether the fixed shaft bracket 215 and the rotating shaft bracket 216 are fully closed and transmit the signal to the control device.

[0105] Specifically, the bracket also includes a top plate 26, which covers the top of the horizontal plate of the vertical plate, the first mounting plate 24, and the second mounting plate 25. Even though the top plate 26 is located above the crossbeam 22, it can protect the components below it. The top plate 26 has a notch, and the bottom end of the top plate 26 is connected to a third sensor bracket 2116. The third sensor 2113 and the fourth sensor 2114 are both mounted on the third sensor bracket 2116 and are located below the notch, which facilitates sensor wiring. The third sensor 2113 is located directly above the maximum open position of the fixed shaft 28 and can detect whether the fixed shaft bracket 215 and the rotating shaft bracket 216 are fully open and transmit the signal to the control device. The fourth sensor 2114 is located directly above the closed position of the fixed shaft bracket 215 and can detect whether the fixed shaft bracket 215 and the rotating shaft bracket 216 are fully closed and transmit the signal to the control device.

[0106] In this way, two sensing blocks can be set on the fixed shaft bracket 215. The two sensing blocks are respectively in sensing cooperation with the third sensor 2113 and the fourth sensor 2114. When the third sensor 2113 senses its corresponding sensing block, the third sensor 2113 will send an opening position signal to the control device. When the fourth sensor 2114 senses its corresponding sensing block, the fourth sensor 2114 will send a closing position signal to the control device.

[0107] Thus, the control device can determine whether the fixed shaft bracket 215 and the rotating shaft bracket 216 are fully open based on the signal obtained from the third sensor 2113, and further determine whether the fixed shaft group and the rotating shaft group are fully open. Similarly, the control device can determine whether the fixed shaft bracket 215 and the rotating shaft bracket 216 are fully closed based on the signal obtained from the fourth sensor 2114, and further determine whether the fixed shaft group and the rotating shaft group are fully closed, thereby enabling the equipment to better control the labeling mechanism 2 to complete automatic labeling.

[0108] Based on the above embodiments, for further preferred settings of the barcode scanner 4, please refer to [reference needed]. Figure 3The vertical plate of the column 21 is equipped with a barcode scanner bracket 41, and the barcode scanner 4 is mounted on the barcode scanner bracket 41. In this way, the barcode scanner 4 and the labeling mechanism 2 are set up in one place, which can save space.

[0109] Understandably, after a period of use, the label paper of label printer 3 needs to be replaced, and even the main body (including turntable mechanism 1, labeling mechanism 2, label printer 3 and barcode scanner 4) may need to be repaired.

[0110] To facilitate easy replacement of the label paper or main body, as a further preferred option based on the above embodiments, please refer to... Figure 1 and Figure 7 The equipment also includes a slide drawer assembly, which includes a drawer body 5 and a slide assembly 6. The drawer body 5 is movable in the extension direction of the slide assembly 6, and the drawer body 5 and the slide assembly 6 are detachably connected. The turntable mechanism 1, the labeling mechanism 2, the label printer 3, and the barcode scanner 4 are all located on the drawer body 5.

[0111] Thus, when it is necessary to replace the label or the main body, the drawer body 5 can be pulled out from the slide rail assembly 6 to remove the entire main body. When it is necessary to reset the main body, the drawer body 5 can be pushed into the slide rail assembly 6 to reset the main body, thereby making it convenient to replace the label or the main body.

[0112] Based on the above embodiments, and considering the specific structures of the drawer body 5 and the slide rail assembly 6, for further preferred embodiments, please refer to... Figure 2 and Figure 7 The drawer body 5 includes a main board 51, a pull plate 52 and two slide plates 53. The pull plate 52 is located at one end of the main board 51 in the length direction, and the two slide plates 53 are located on both sides of the main board 51 in the width direction. The slide rail assembly 6 includes two slide rails 61 and a frame. The two slide rails 61 are located on both side plates 62 in the width direction of the frame, and the two slide rails 61 are detachably and slidably connected to the two slide plates 53.

[0113] In this way, the two sliding plates 53 and the two slide rails 61 slide in a corresponding and coordinated manner, allowing the drawer body 5 to be pushed and pulled smoothly, preventing damage to its components due to excessive vibration when pulling the drawer body 5. In addition, the operator can simply push and pull the pull plate 52 to reset or pull out the drawer body 5, making it more convenient to replace labels or repair the main body.

[0114] Regarding the specific connection method between skateboard 53 and slide rail 61, as follows: Figure 7As shown, the slide rail 61 has a groove 63 extending along its length, with one end of the groove 63 being closed and the other end being open. The slide plate 53 has a slide bar extending along its length on the side facing the other slide plate 53, and the slide bar is slidably embedded in the groove 63. It should be noted that the open end of the groove 63 is located at the end of the frame adjacent to the pull plate 52, ensuring that the slide bar slides out from the open end of the groove 63, thereby allowing the drawer body 5 to be fully pulled out from the slide rail assembly 6.

[0115] Based on the above embodiments, as a further preferred option, please refer to... Figure 2 and Figure 7 The bottom end of the main board 51 away from the pull plate 52 is connected to a sleeve 54, and the bottom end of the main board 51 adjacent to the pull plate 52 is connected to an electromagnet suction plate 55 and an electromagnet suction plate 68. One end of the skeleton in the length direction is provided with a positioning shaft 65 that is compatible with the sleeve 54, and the other end of the skeleton in the length direction is provided with an electromagnet 68 and a positioning sensor 69. When the electromagnet suction plate 68 is attracted to the electromagnet 68, the electromagnet suction plate 55 triggers the positioning sensor 69 to send a positioning signal to the control device.

[0116] Specifically, the bottom end of the main board 51 away from the pull plate 52 is provided with a first upright plate, and a sleeve 54 is provided on the first upright plate. The bottom end of the main board 51 adjacent to the pull plate 52 is connected to an electromagnet suction plate 55 and an electromagnet suction plate 68. A second upright plate 64 is provided between one end of the two side plates 62 of the frame. The second upright plate 64 is provided with a positioning shaft 65 that is compatible with the sleeve 54. A second horizontal plate 66 is provided between the other ends of the two side plates 62 of the frame. A fixing plate 67 is vertically provided on the second horizontal plate 66. An electromagnet 68 and a positioning sensor 69 are mounted side by side on the fixing plate 67. The electromagnet 68 is attracted to the electromagnet suction plate 55, and the electromagnet suction plate 55 is triggered and sensed by the positioning sensor 69.

[0117] In this way, when resetting the main body, the drawer body 5 pull plate 52 is pushed, and the positioning shaft 65 is first inserted into the sleeve 54. When the electromagnet 68 of the drawer body 5 is attracted to the electromagnet 68 of the slide rail assembly 6, the electromagnet 55 of the drawer body 5 triggers the position sensor 69 of the slide rail assembly 6. The position sensor 69 can send a position signal to the control device to indicate to the operator that the reset has been completed. In this way, it is convenient for the operator to judge whether the main body has been reset, thereby ensuring that the main body is reset.
