Description

Technical Field

[0001] The present application relates to the field of label printing equipment, and in particular to a label printer. Background Art

[0002] Conventional label sticking devices are mainly used to stick labels on the body of a test tube. If a label needs to be stuck on the cap of a test tube, the test tube needs to be sunk into the device so that the body is in the labeling operation area of ​​the device. In this case, since the test tube is completely sunken inside the machine, it is difficult to detect when the test tube is placed incorrectly, and it is also difficult to adjust, which is not conducive to ensuring the quality of labeling.

[0003] In view of this, the purpose of this application is to overcome the deficiencies in the prior art and to provide a labeling printer that can easily control and adjust the posture of the test tubes and improve the labeling quality.

[0004] This application provides the following technical solutions:

[0005] The embodiment of the present application provides a labeling printer, which includes a scanning device, a label printing device and a labeling device;

[0006] The scanning device is used to scan and obtain the ID information of the end of the test tube, the label printing device is electrically connected to the scanning device, the label printing device is used to generate printing information and print labels according to the ID information, and the labeling device is used to stick the label to the side wall of the test tube; wherein

[0007] The labeling device includes a pair of tube pressing rollers, a roller frame, a first driving member, a label pressing roller, a second driving member and a supporting member; the pair of tube pressing rollers are rotatably connected to the roller frame, and the pair of tube pressing rollers and the label pressing rollers are arranged in parallel, a clamping area is formed between the pair of tube pressing rollers, the label pressing rollers and the supporting member, and the supporting member can support the test tube located in the clamping area, the first driving member is connected to the roller frame, the first driving member can drive the roller frame to move, and the movement of the roller frame is configured to enable the pair of tube pressing rollers to approach or move away from the label pressing roller; the second driving member is connected to the label pressing roller, and the second driving member can drive the label pressing roller to rotate.

[0008] In one embodiment, the carrier has a transparent area; wherein the transparent area can expose the label of the end of the test tube abutting against the carrier.

[0009] In one embodiment, the labeling device further comprises:

[0010] A buffer member, wherein the first driving member is connected to the roller frame through the buffer member, and the buffer member is configured to be elastically deformable in the moving direction of the roller frame.

[0011] In one embodiment, the buffer comprises:

[0012] A transfer part, a guide part and an elastic part, wherein the first driving member is connected to the transfer part, and the transfer part is connected to the roller frame through the elastic part;

[0013] Wherein, the elastic part is set as an elastic structure, and the adapter part is also connected to the roller frame through the guide part, so that when the elastic part is in elastic deformation, the guide part can limit the roller frame to approach or move away from the adapter part in its moving direction.

[0014] In one embodiment, the guide portion comprises:

[0015] A guide rod and a spring, the adapter having a slideway, the slideway and the guide rod both extending along the moving direction of the roller frame, one end of the guide rod being connected to the roller frame, and the other end being slidably inserted into the slideway, the spring being sleeved on the guide rod, and the spring being clamped between the adapter and the roller frame.

[0016] In one embodiment, the labeling device comprises:

[0017] A third driving member is connected to the bearing member, and can drive the bearing member to move along a preset direction, wherein the preset direction is parallel to the axial direction of the label pressing roller. The third driving member can accurately adjust the labeling position.

[0018] In one embodiment, the width of the contact area between the support and the test tube in the moving direction of the roller frame is smaller than the diameter of the test tube; wherein, when the test tube is in a clamped state, there is a gap between the support and the tube pressing roller and the label pressing roller respectively.

[0019] In one of the embodiments, in an initial state, the tube pressing roller, the label pressing roller and the supporting member can be positioned opposite to the test tube in the clamping area so that the test tube is located in the clamping area and parallel to the tube pressing roller.

[0020] The embodiments of the present application have the following advantages:

That is to say, the movement of the roller frame is controlled by the first driving member to achieve precise position control and posture adjustment of the test tube. Among them, when the test tube is stably clamped, the second driving member is started to drive the label pressing roller to rotate, and the label pressing roller works together with the tube pressing roller during the rotation process to apply uniform pressure to the test tube, ensuring that the label can be smoothly and firmly attached to the test tube through the label pressing roller. The bearing member provides necessary support for the test tube in this process, ensuring that the test tube remains stable during the entire labeling process, avoiding displacement or tipping caused by external force, thereby improving the stability and quality of the labeling operation. The scanning device captures the ID information, and it will immediately transmit the information to the label printing device electrically connected to it through an electronic signal.

The generated label is then printed out instantly and accurately attached to the corresponding test tube by the labeling device.

[0022] Therefore, through the adjustable tube pressing roller and label pressing roller, the device can flexibly adapt to test tubes of different sizes, and accurately adjust the position and posture of the test tube before labeling, which significantly improves the accuracy and quality of labeling. In addition, since the test tube is placed in the clamping area in an inverted position, only part of the test tube needs to enter the device, and the adjustment of its placement posture becomes more intuitive and convenient. The operator can more easily find and correct the error of the test tube position or posture, avoiding the problem of difficult adjustment due to the test tube being deeply trapped inside the device. In addition, the coordinated use of the first drive member and the second drive member makes the entire labeling process fast and automated, reduces manual intervention, improves the efficiency of the labeling operation, and enables the device to adapt to test tubes of different specifications, meet the needs of different test tube labeling in laboratories, medical institutions or production lines, and enhance the versatility and practicality of the equipment. In addition, the entire process from scanning to printing and labeling is done in one go, which not only ensures high efficiency, but also ensures the uniqueness and accuracy of each test tube label. Such an integrated system significantly improves the efficiency and accuracy of laboratory management, especially when processing a large number of samples. It can effectively avoid human errors and accelerate sample tracking and management. It is extremely important for clinical trials, biobank management and various scientific research activities.

The terms used herein in the specification of the template are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0035] In the related art, when using test tubes, a label pasting device is mostly used to print labels and paste the printed labels on the test tubes. Conventional label pasting devices are mainly used to paste labels on the tube body of the test tube. If a label needs to be pasted on the tube cover of the test tube, the test tube needs to be sunk into the device so that the tube body is in the labeling operation area of ​​the device. In this case, since the test tube is completely sunken inside the machine, when the test tube is placed in an incorrect posture, it is not easy to be discovered and adjusted, which is not conducive to ensuring the quality of labeling.

[0036] like Figure 1 , Figure 2 and Figure 3As shown, in order to solve the above technical problems, the embodiment of the present application provides a labeling printer, which includes a scanning device 200, a label printing device 300 and a labeling device 100; the scanning device 200 is used to scan and obtain the ID information of the end of the test tube 400, the label printing device 300 is electrically connected to the scanning device 200, the label printing device 300 is used to generate printing information according to the ID information and print a label, and the labeling device 100 is used to stick the label to the side wall of the test tube 400; the labeling device 100 includes a pair of tube pressing rollers 130, a roller frame 120, a first driving member 140, a label pressing roller 150, a second driving member 180 and a supporting member 160; a pair of tube pressing rollers 130 are rotatably connected to the roller frame 120, and the pair of tube pressing rollers 130 and the label pressing roller 150 are arranged in parallel, a clamping area is formed between the pair of tube pressing rollers 130, the label pressing roller 150 and the supporting member 160, a first driving member 140 is connected to the roller frame 120, the first driving member 140 can drive the roller frame 120 to move, and the movement of the roller frame 120 is configured to enable the pair of tube pressing rollers 130 to approach or move away from the label pressing roller 150; a second driving member 180 is connected to the label pressing roller 150, the second driving member 180 can drive the label pressing roller 150 to rotate; the supporting member 160 can support the test tube 400 located in the clamping area.

[0037] In this embodiment, the scanning device 200 generally adopts technologies such as a barcode reader, a two-dimensional code scanner or an RFID reader, and is installed at an appropriate position of the label printer so as to automatically capture the ID information attached to the end of the test tube 400 when the test tube 400 enters the processing area. This step is automated and does not require manual intervention, which greatly improves the processing speed and accuracy.

[0038] Once the scanning device 200 captures the ID information, it will immediately transmit the information to the label printing device 300 electrically connected thereto via an electronic signal. In this process, a simple data verification or comparison with a database is involved to ensure the accuracy and latest status of the information.

[0039] After receiving the ID information, the label printing device 300 generates a personalized label containing the specific ID information according to a preset template or logic. This process can be customized to meet the needs of different laboratories or research projects. The generated label is then printed out instantly and accurately attached to the corresponding test tube 400 through the labeling device 100. The entire process from scanning to printing and labeling is done in one go, which not only ensures high efficiency, but also ensures the uniqueness and accuracy of the label of each test tube 400. Such an integrated system significantly improves the efficiency and accuracy of laboratory management, especially when processing a large number of samples, it can effectively avoid human errors and accelerate the tracking and management of samples, which is extremely important for clinical trials, biological sample library management and various scientific research activities.

[0040] In this embodiment, a pair of tube pressing rollers 130 and label pressing rollers 150 are arranged in parallel, and the clamping area formed between them is the key area for positioning and labeling the test tube 400. The first driving member 140 is connected to the roller frame 120, and can control the movement of the roller frame 120, thereby adjusting the distance between the tube pressing roller 130 and the label pressing roller 150. This design enables the device to adapt to test tubes 400 of different diameters, and at the same time facilitates the adjustment of the correct position of the test tube 400 before labeling, and is used to clamp the test tube 400, thereby improving the control ability of the test tube 400 posture.

[0041] In addition, during labeling, the tube pressing roller 130 and the label pressing roller 150 contact and clamp the test tube 400, and the label pressing roller 150 is driven to rotate by the second driving member 180 to attach the label to the surface of the test tube 400. This rotation action cooperates with the clamping of the tube pressing roller 130 to ensure that the label can be flatly and accurately attached to the test tube 400, whether it is the body of the test tube 400 or the tube cover.

[0042] The carrier 160 can stably carry the test tube 400 to ensure that the test tube 400 is always in the clamping area, and then cooperate with the pair of tube pressing rollers 130 and the label pressing roller 150 to clamp the test tube 400. It should be noted that the clamping area is formed between the carrier 160, the pair of tube pressing rollers 130 and the label pressing roller 150.

[0043] Exemplarily, the support member 160 may be configured as a plate-like structure, so that the end of the test tube 400 is in surface contact with the support member 160 , thereby maintaining and improving the stability of the support.

[0044] For example, the tube pressing roller 130 and the label pressing roller 150 are both arranged vertically, and the supporting member 160 is arranged horizontally, so that the test tube 400 placed on the supporting member 160 is in a vertical state. Of course, in other embodiments, the tube pressing roller 130, the label pressing roller 150 and the supporting member 160 can also be arranged tilted, and the axial directions of the supporting member 160 and the tube pressing roller 130 are perpendicular, which is not specifically limited here.

[0045] Therefore, through the adjustable tube pressing roller 130 and label pressing roller 150, the device can flexibly adapt to test tubes 400 of different sizes, and accurately adjust the position and posture of the test tube 400 before labeling, which significantly improves the accuracy and quality of labeling. In addition, since the test tube 400 is placed in the clamping area in an inverted position, only part of the test tube 400 needs to enter the device, and the adjustment of its placement posture becomes more intuitive and convenient. The operator can more easily find and correct the error of the position or posture of the test tube 400, avoiding the problem of the test tube 400 being deeply trapped in the device and difficult to adjust. In addition, the coordinated use of the first drive member 140 and the second drive member 180 makes the entire labeling process fast and automated, reduces manual intervention, improves the efficiency of the labeling operation, and enables the device to adapt to test tubes 400 of different specifications, meet the needs of medical institutions for labeling of different test tubes 400, and enhance the versatility and practicality of the equipment.

[0046] like Figure 3 As shown, in some embodiments, the carrier 160 has a transparent area; wherein the transparent area can expose the label of the end of the test tube 400 abutting against the carrier 160.

[0047] That is, when it is necessary to scan the ID information at the end of the test tube 400, the ID information is exposed from the transparent area, so that it is convenient for the scanning device 200 to scan and obtain the information. For example, the ID information can be a QR code to bind the user's personal information, such as personal identity information, and the scanning device 200 can be a barcode scanner to read the QR code. Of course, it can also be set in other forms, which are not specifically limited here.

[0048] Exemplarily, the carrier 160 is configured as a transparent plate; of course, in other embodiments, an opening may also be provided on the carrier 160, and the opening forms a transparent area to expose the ID information from the opening.

[0049] like Figure 1 As shown, in some embodiments, the labeling device 100 further includes a buffer 190 , and the first driving member 140 is connected to the roller frame 120 via the buffer 190 . The buffer 190 is configured to be elastically deformable in the moving direction of the roller frame 120 .

[0050] In these embodiments, the elastic buffer 190 can provide gentle power transmission during the movement of the roller frame 120, reduce direct hard collisions with the test tube 400, extend the service life of the equipment, and protect components such as the first drive member 140 and the roller frame 120 from damage caused by sudden impacts.

[0051] Furthermore, the elastic deformation of the buffer 190 can automatically compensate for slight displacements caused by equipment vibration or the test tube 400 not being placed completely flat to a certain extent, which helps to improve the accuracy of the labeling position and the flatness of the label pasting, thereby ensuring the labeling quality.

[0052] In addition, the buffer member 190 is configured to allow elastic deformation only in the moving direction of the roller frame 120. That is, the first driving member 140 can cooperate with the buffer member 190 to adjust the squeezing force of the tube pressing roller 130 on the test tube 400, thereby further controlling the labeling quality.

[0053] In some embodiments, the first driving member 140 is configured as a linear moving module. In other embodiments, the first driving member 140 may also be configured as an electric push rod, a pneumatic cylinder, etc., which are not specifically limited here, as long as it can drive the tube pressing roller 130 to approach or move away from the label pressing roller 150.

[0054] like Figure 1 As shown, in some embodiments, a pair of tube pressing rollers 130 are symmetrically arranged about the marking roller 150, that is, the marking roller 150 is located on the symmetry plane of the pair of tube pressing rollers 130, and the moving direction of the roller frame 120 is located on the symmetry plane of the pair of tube pressing rollers 130 and is arranged perpendicular to the axis of the marking roller 150.

[0055] In some embodiments, the first driving member 140 is configured as a driving motor, and the driving motor is connected to the marking roller 150 to drive the marking roller 150 to rotate.

[0056] like Figure 1 As shown, in some embodiments, the buffer member 190 includes a transition portion 110, a guide portion and an elastic portion, the first driving member 140 is connected to the transition portion 110, and the transition portion 110 is connected to the roller frame 120 through the elastic portion; wherein the elastic portion is configured as an elastic structure, and the transition portion 110 is also connected to the roller frame 120 through the guide portion, so that when the elastic portion is in elastic deformation, the guide portion can limit the roller frame 120 to approach or move away from the transition portion 110 in its moving direction.

[0057] In this embodiment, the adapter 110 serves as a direct connection point between the first driving member 140 (such as a motor) and the buffer member 190. The function of the adapter 110 is to effectively transmit the driving force to the elastic member and the roller frame 120. The elastic member is usually composed of a spring 191, an elastic material or a similar deformable element, and its design purpose is to allow a certain elastic displacement between the roller frame 120 and the adapter 110 under the drive of the first driving member 140. This elastic deformation can absorb the vibration and impact force generated when the equipment is running, reduce the influence of these external forces on the precision labeling process, and adjust the squeezing force of the tube pressing roller 130 and the label pressing roller 150 on the test tube 400, thereby protecting the entire device and improving the labeling accuracy.

[0058] It should be noted that the guide part ensures the directionality and limit function of the roller frame 120 during the movement. When the elastic part is deformed under the force, the guide part guides and limits the movement trajectory of the roller frame 120 through its structural design, so that it approaches or moves away from the adapter 110 in a predetermined direction, while ensuring the smoothness of the movement process and the accuracy of repeated positioning, avoiding unnecessary lateral deviation or swing.

[0059] like Figure 1 As shown, in some embodiments, the guide portion includes a guide rod 192 and a spring 191, the adapter portion 110 has a slide, the slide and the guide rod 192 both extend along the moving direction of the roller frame 120, one end of the guide rod 192 is connected to the roller frame 120, and the other end is slidably inserted into the slide, the spring 191 is sleeved on the guide rod 192, and the spring 191 is clamped between the adapter portion 110 and the roller frame 120.

[0060] In this embodiment, the guide rod 192 is combined with the slideway on the adapter 110 to form a linear guide system. One end of the guide rod 192 is fixed to the roller frame 120, and the other end slides in the slideway of the adapter 110. This design ensures the linearity of the roller frame 120 during movement, and can maintain the accuracy of its movement trajectory even when disturbed by external forces, which is crucial for accurately controlling the labeling position.

[0061] The spring 191 is sleeved on the guide rod 192 and is located between the adapter 110 and the roller frame 120. The function of the spring 191 is not only to provide elastic force to keep the guide rod 192 in the slideway with appropriate contact pressure to ensure smooth movement without jamming, but also when the roller frame 120 moves, the compression and rebound of the spring 191 can absorb and alleviate the impact and vibration during the movement, further improving the running stability of the entire device and reducing the influence of vibration on the labeling accuracy.

[0062] Obviously, the combination of the guide rod 192 and the spring 191 forms a connection system that is both stable and elastic. When the roller frame 120 needs to move due to external force, the elastic deformation of the spring 191 can absorb energy in time, while the guide rod 192 ensures the linearity of the movement. Under the combined action of the two, the moving direction of the roller frame 120 is precisely controlled and dynamically adjusted, which improves the stability and accuracy of the labeling process.

[0063] For example, a linear bearing is provided on the adapter 110, and the inner hole of the linear bearing forms the above-mentioned slideway. It is foreseeable that the use of a linear bearing to construct the slideway can reduce the friction between the guide rod 192 and the slideway.

[0064] like Figure 1 and Figure 3 As shown, in some embodiments, the labeling device 100 includes a third driving member 170, and the third driving member 170 is connected to the carrier 160. The third driving member 170 can drive the carrier 160 to move along a preset direction, and the preset direction is parallel to the axial direction of the labeling roller 150. The third driving member 170 can accurately adjust the labeling position. Taking a cryogenic tube as an example, the cryogenic tube is composed of a tube cap and a tube body. By driving the carrier 160 to move by the third driving member 170, both the cap of the cryogenic tube and the tube body can be labeled.

[0065] In these embodiments, the third driving member 170 is responsible for driving the carrier 160 to move along a preset direction parallel to the axis of the labeling roller 150, which means that the carrier 160 loaded with the test tube 400 can be automatically sent to the labeling position, thereby realizing the automatic feeding of the test tube 400, that is, it is possible to adjust the labeling position of the test tube 400. This method significantly improves the automation and work efficiency of the labeling operation, reduces the reliance on manual operation, and can accurately control the labeling position.

[0066] For ease of understanding, through the precise control of the third driving member 170, the movement of the carrier 160 can be executed according to a preset program or instruction, ensuring that the test tube 400 is in an accurate position when it reaches the labeling area, which is crucial to improving labeling accuracy and labeling position.

[0067] For example, the roller frame 120 moves along the X-axis direction, the supporting member 160 moves along the Y-axis direction, and then the third driving member 170 cooperates with the aforementioned buffer member 190 and the guide part to achieve precise positioning of the test tube 400 in the X and Y axes, ensuring that the label can be affixed to the correct position every time.

[0068] In addition, since the carrier 160 can move parallel to the axial direction, this means that the device can adapt to test tubes 400 of different lengths through program control, and it only needs to adjust the moving distance of the carrier 160, which increases the versatility and flexibility of the labeling device 100. Obviously, the design of automatic sample delivery reduces the time of manually adjusting the position of the test tube 400, making the labeling process continuous and fast, especially when processing a large number of test tubes 400 in batches, which can significantly improve the overall production efficiency and throughput. In addition, automation and precise control reduce the uncertainty caused by manual operation, avoid labeling errors caused by human factors, and improve the consistency and reliability of labeling.

[0069] like Figure 1 As shown, in some embodiments, the width of the contact area between the supporting member 160 and the test tube 400 in the moving direction of the roller frame 120 is smaller than the diameter of the test tube 400; wherein, when the test tube 400 is in a clamped state, there is a gap between the supporting member 160 and the tube pressing roller 130 and the marking roller 150 respectively.

[0070] In this embodiment, by setting the width of the contact area of ​​the carrier 160 and the position of the carrier 160, when the tube pressing roller 130 and the label pressing roller 150 clamp the test tube 400, the tube pressing roller 130 and the label pressing roller 150 do not contact the carrier 160. In other words, the width of the contact area between the carrier 160 and the test tube 400 is smaller than the diameter of the test tube 400. Such a design ensures that the test tube 400 can be firmly held on the carrier 160 during the labeling process, while allowing the tube pressing roller 130 and the label pressing roller 150 to effectively clamp and operate the test tube 400 from both sides. Such a size arrangement avoids interference between the carrier 160 and the tube pressing roller 130 and the label pressing roller 150, and ensures that the tube pressing roller 130 and the label pressing roller 150 can smoothly act on the surface of the test tube 400 for accurate positioning and labeling.

[0071] Exemplarily, the carrier 160 is a transparent support sheet, which is replaceable to fit test tubes 400 of different sizes, and is set as a rectangular parallelepiped, and the width of the transparent support sheet is smaller than the minimum diameter of the test tube 400, so that the transparent support sheet can be raised to the clamping area, and after the test tube 400 is placed, the label pressing roller 150 and the tube pressing roller 130 will not touch the transparent support sheet and cause interference during clamping, so that the test tube 400 will not be clamped tightly. Of course, in other embodiments, the transparent support sheet can also be set as a cube, a triangular prism, etc., which is not specifically limited here.

[0072] like Figure 1As shown, in some embodiments, in the initial state, the tube pressing roller 130 , the marking roller 150 and the supporting member 160 can limit the test tube 400 placed in the clamping area so that the test tube 400 is located in the clamping area and parallel to the tube pressing roller 130 .

[0073] In this embodiment, when the test tube 400 is placed in the clamping area, the tube pressing roller 130 and the label pressing roller 150 work together on the test tube 400 through their relative positions and the design of the clamping area, so that the test tube 400 is accurately limited in the horizontal direction. This means that no matter how the test tube 400 is placed, it can be quickly guided to an ideal position parallel to the tube pressing roller 130, laying the foundation for the subsequent labeling operation.

[0074] The supporting member 160 not only provides a supporting platform in this process, but also participates in the limiting process, and cooperates with the tube pressing roller 130 and the label pressing roller 150 to ensure that the test tube 400 is also stabilized in the vertical direction, preventing tilting or sliding due to improper alignment before labeling, thereby increasing the stability of labeling.

[0075] Obviously, this design simplifies the operation process, allowing operators to quickly complete the positioning of the test tube 400 without tedious manual adjustments, thereby improving the efficiency of the labeling operation, which is particularly important in scenarios where a large number of test tubes 400 need to be processed. In addition, through this automatic limit mechanism, it is ensured that the test tube 400 is in an ideal position and posture before labeling, thereby directly improving the accuracy and consistency of labeling and reducing labeling failures or quality problems caused by human operating errors.

[0076] For example, in the ready state before labeling is started, the tube pressing roller 130 and the label pressing roller 150 are both at a distance from the test tube 400, so as to ensure that the test tube 400 can be easily taken and placed. At the same time, the tube pressing roller 130 and the label pressing roller 150 surround the test tube 400 to prevent the test tube 400 from falling or tilting after being placed. Of course, in other embodiments, the tube pressing roller 130 and the label pressing roller 150 are both at a distance of 3 mm, 4 mm, or 5 mm from the test tube 400, which is not specifically limited here and is specifically selected according to the diameter of the test tube 400.
