Description

Technical Field

[0001] This utility model belongs to the field of laser marking equipment technology, and more specifically, relates to a semi-automatic multi-functional laser marking instrument for cryopreservation tubes. Background Technology

[0002] Cryopreservation tubes, as key containers for the storage and transportation of biological samples, are widely used in life sciences, medical research, drug development, and clinical diagnostics. To achieve traceable management of samples, cryopreservation tubes typically require labeling. Laser marking, as a non-contact, pollution-free, and high-precision marking method, has been widely adopted in cryopreservation tube labeling. However, current cryopreservation tube laser marking equipment generally suffers from limitations in functionality, applicability, and cost. Specifically, existing equipment is mostly designed for specific specifications or types of cryopreservation tubes, lacking compatibility support for various types of cryopreservation tubes (such as different diameters, heights, materials, or cap structures). Furthermore, their complex design and low modularity result in high unit prices, limiting their widespread adoption in small and medium-sized laboratories or institutions with limited budgets.

[0003] To address these issues, some patents and published literature have proposed improvements through equipment structure optimization, control system upgrades, and modular design. For example, some patents suggest adapting to cryovials of different sizes by replacing clamps or adjusting positioning devices, thereby improving the equipment's versatility. Furthermore, some technical solutions introduce multi-axis motion platforms or automatic optical adjustment systems to achieve flexible control over the marking positions on the surfaces of different types of cryovials. Other manufacturers are attempting to adopt standardized interfaces and modular components to reduce equipment maintenance costs and lower the barriers to expansion.

[0004] Although existing technologies have made some efforts to improve the versatility and economy of laser marking machines for cryopreservation tubes, there are still many shortcomings. For example, most equipment is still designed based on fixed workstations or special fixtures, and the marking direction is fixed, making it difficult to quickly switch to adapt to different models of cryopreservation tubes, resulting in cumbersome operation and low efficiency. Secondly, the control system generally adopts a single programming logic, lacking adaptive adjustment capabilities, and cannot automatically match the optimal marking parameters according to the type of cryopreservation tube, affecting the marking quality and consistency. In addition, existing equipment often does not consider future functional expansion and module updates, resulting in a limited equipment life cycle and a low return on investment for users. Utility Model Content

[0005] To address the aforementioned deficiencies or improvement needs of existing technologies, this utility model provides a semi-automatic multi-functional cryopreservation tube laser marking instrument. Through a support cavity and a rotating unit, the laser can cover multiple positions around the cryopreservation tube in five directions, enabling omnidirectional and multi-angle marking operations. This greatly enriches the expressive forms and information capacity of the marking content, thus adapting to marking operations on various types of cryopreservation tubes. Secondly, by setting up a support unit, a support unit, a laser marking unit, and a rotating unit, and combining them with a first moving mechanism to achieve a sliding connection of the support unit on the base plate, the equipment possesses good structural stability and spatial adaptability. Furthermore, it effectively improves the equipment's compatibility with cryopreservation tubes of different sizes and specifications, enhances positioning accuracy and operational stability during operation, thereby effectively ensuring the clarity and consistency of the marking.

Furthermore, this half-width fitting structure design has excellent versatility; by replacing different specifications of the support platform, it can adapt to cryopreservation tubes of various sizes and shapes, greatly expanding the equipment's application range and solving the problem of poor compatibility caused by traditional equipment only being able to adapt to a single type of cryopreservation tube.

[0018] 3. The laser marking instrument of this utility model, through the coordinated arrangement of the first motor, the connecting transmission plate, and the first beam transmission tube, enables the marking head to rotate around the first beam transmission tube as the center, thereby achieving circumferential scanning and all-round coverage of the area to be marked by the laser beam on the cryopreservation tube. This effectively solves the marking blind spot problem existing in the traditional fixed marking method, improving the integrity and readability of the marking. Secondly, the first beam transmission tube is movably connected to one side of the marking head through a bearing in the connecting transmission plate, ensuring a stable transmission path of the laser beam during the rotation of the marking head, avoiding optical path deviation or energy attenuation caused by mechanical rotation, and further ensuring the accuracy and consistency of marking. In addition, this structural design integrates key transmission components inside the connecting transmission plate, effectively improving space utilization, enhancing the overall rigidity and anti-interference ability of the system, and contributing to improving the stability and service life of the equipment.

[0019] 4. The laser marking instrument of this utility model marks the cryopreservation tube by rotating it. This allows for continuous scanning and marking of the circumferential surface of the cryopreservation tube with a laser beam without adjusting the position of the marking head. This effectively solves the problem of marking blind spots caused by limited movement or inaccurate positioning of the marking head in traditional equipment, significantly improving the integrity and recognizability of the marking. At the same time, it avoids the instability of the optical path that may be caused by the relative displacement between moving parts, ensuring the efficiency and consistency of laser energy during transmission. This improves the accuracy and clarity of marking, effectively simplifies the complexity of the optical system, and reduces the overall manufacturing and maintenance costs of the equipment.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] Example 1 like Figures 1 to 4 , Figure 9As shown, one embodiment of this utility model provides a semi-automatic multifunctional cryopreservation tube laser marking instrument, including: a support unit 1, a carrier unit 2, a laser marking unit 3, and a rotating unit 4; the support unit 1 is disposed on a workbench, and includes a base plate 11 and a first bracket 12 fixedly disposed on the upper end of the base plate; the carrier unit 2 is slidably connected to the base plate 11 through a first moving mechanism 13 disposed on the upper end of the base plate 11, and its upper end is provided with a carrier cavity adapted to the cryopreservation tube 5; the laser marking unit 3 is disposed on the first bracket 12, and its marking head 31 is aligned with the cryopreservation tube 5 on the carrier unit 2; the rotating unit 4 is rotatably connected to the marking head 31 or the cryopreservation tube 5 and drives the marking head 31 or the cryopreservation tube 5 to rotate, so that the laser scans the area to be marked on the cryopreservation tube 5. This invention's laser marking instrument, through its support cavity and rotating unit, allows the laser to cover multiple positions around the cryopreservation tube in five directions, enabling omnidirectional and multi-angle marking operations. This greatly enriches the expressive forms and information capacity of the marking content, thus adapting to marking operations on various types of cryopreservation tubes. Secondly, by setting up a support unit, a support unit, a laser marking unit, and a rotating unit, and combining them with a first moving mechanism to achieve a sliding connection of the support unit on the base plate, the equipment possesses good structural stability and spatial adaptability. Furthermore, it effectively improves the equipment's compatibility with cryopreservation tubes of different sizes and specifications, enhances the positioning accuracy and operational stability during operation, and thus effectively ensures the clarity and consistency of the marking. At the same time, the modular approach of this structure, with standardized interfaces between various functional units, facilitates later maintenance, upgrades, and expansions, reducing overall manufacturing and usage costs.

[0024] It should be noted that the laser marking unit 3 is a laser marking instrument in the prior art, including but not limited to a laser generator, a beam transmission system, a galvanometer scanning system, and a focusing system, and the marking head 31 includes at least a galvanometer scanning system and a focusing system to achieve stability and accuracy in marking the cryopreservation tube 5.

[0025] like Figures 1 to 4 As shown, the bottom end of the base plate 11 of the support unit 1 is evenly provided with a number of pads 14 to ensure that the device as a whole is stably placed on the workbench.

[0026] It should be noted that in this embodiment, the first moving mechanism 13 is a guide component commonly used in the prior art, such as a guide rail. Of course, in other embodiments, the first moving mechanism 13 may also be other devices, and this utility model does not limit this.

[0027] It should be noted that in other embodiments, other types of support units may be used to ensure the smooth operation of other components. No specific limitations are made here, but these solutions are all within the protection scope of this utility model.

[0028] In an optional embodiment, a limiting block 111 is provided at the upper end of the base plate 11 to prevent the bearing unit 2 from sliding out of the marking area and to improve the positioning accuracy.

[0029] like Figures 1 to 4 As shown, the support unit 2 includes a first support platform 21, at least one of which is detachably connected to the first moving mechanism 13, and its upper surface is provided with a plurality of support cavities adapted to the cryopreservation tube 5 at equal intervals along the moving direction of the first moving mechanism 13.

[0030] Furthermore, the shape of the bearing cavity is adapted to the horizontal quarter or half-section profile of the cryopreservation tube 5 in a horizontally placed state.

[0031] It should be noted that the above design, employing a multi-cavity layout, enables the simultaneous support and positioning of multiple cryopreservation tubes 5, thereby improving the equipment's continuous operation capability and marking efficiency. It also effectively avoids cycle time delays caused by single-station operations, improving the overall production cycle time. Secondly, the matching design between the support cavity and the quarter or half-section profile of the cryopreservation tube allows for stable fitting and self-centering positioning within the support cavity, reducing displacement deviations caused by vibration or external forces, thus ensuring positional accuracy and marking quality during laser marking. Furthermore, this half-width fitting structure design has excellent versatility; by replacing different specifications of the support platform, it can adapt to cryopreservation tubes 5 of various sizes and shapes, greatly expanding the equipment's application range and solving the problem of poor compatibility caused by traditional equipment only being able to adapt to a single type of cryopreservation tube.

[0032] like Figures 1 to 4 As shown, the rotating unit 4 includes: a first motor 41 and a connecting transmission plate 42; the first motor 41 is fixedly disposed on one side of the connecting transmission plate 42, and its output shaft passes through the connecting transmission plate 42; the connecting transmission plate 42 is a hollow plate, one end of which is fixedly connected to the first beam transmission tube 32, and the first motor 41 and the first beam transmission tube 32 are located on the same side of the connecting transmission plate 42.

[0033] Furthermore, the first beam transmission tube 32 is movably connected to one side of the marking head 31 via a bearing within the connecting transmission plate 42 (not shown in the figure) to ensure that the beam is stably transmitted to the marking head 31 through the first beam transmission tube 32.

[0034] Furthermore, the output shaft of the first motor 41 is rotatably connected to one side of the marking head 31 via a connector within the connecting transmission plate 42 (not shown in the figure). It can be understood that the connector can be a belt or gear transmission mechanism, so that the marking head 31 rotates at a certain angle around the first beam transmission tube 32 under the drive of the first motor 41, and completes the marking operation on the cryopreservation tube 5.

[0035] It should be noted that, through the above design, the coordinated arrangement of the first motor 41, the connecting transmission plate 42, and the first beam transmission tube 32 enables the marking head 31 to rotate around the first beam transmission tube, thereby achieving circumferential scanning and all-round coverage of the area to be marked on the cryopreservation tube by the laser beam. This effectively solves the problem of blind spots in traditional fixed marking methods, improving the integrity and readability of the markings. Secondly, the first beam transmission tube 32 is movably connected to one side of the marking head 31 within the connecting transmission plate 42 via a bearing, ensuring a stable transmission path for the laser beam during the rotation of the marking head 31. This avoids optical path deviation or energy attenuation caused by mechanical rotation, further ensuring the accuracy and consistency of the marking. In addition, this structural design integrates key transmission components inside the connecting transmission plate 42, effectively improving space utilization and enhancing the overall rigidity and anti-interference capability of the system, which is beneficial to improving the stability and service life of the equipment.

[0036] In an optional embodiment, the cryovial 5 includes polypropylene cryovials and polyethylene cryovials, which can improve the marking quality while effectively ensuring the safety and traceability of the sample. It is understood that the laser marking instrument of this embodiment can also be used for marking other types and sizes of sample storage tubes, and this is not a limitation.

[0037] It should be noted that the laser marking unit 3 also includes an electronic device 33, which includes at least a memory, a processor, and a computer program stored in the memory and capable of running on the processor. When the processor executes the computer program, it realizes the marking operation of the laser marking unit 3 on various types of cryopreservation tubes 5 in this embodiment.

[0038] like Figure 9As shown, the electronic device 33 in this embodiment may include a processor 331, a network interface 334, and a memory 335. Furthermore, the electronic device 33 may also include a user interface 333 and at least one communication bus 332. The communication bus 332 is used to enable communication between these components. The user interface 333 may include a display screen and a keyboard; optionally, the user interface 333 may also include a standard wired interface or a wireless interface. The network interface 334 may optionally include a standard wired interface or a wireless interface (such as a Wi-Fi interface). The memory 335 may be a high-speed RAM or non-volatile memory, such as at least one disk storage device. Optionally, the memory 335 may also be at least one storage device located remotely from the aforementioned processor 331. Figure 9 As shown, the memory 335, which is a computer-readable storage medium, may include an operating system, a network communication module, a user interface module, and a device control application.

[0039] like Figure 9 In the electronic device 33 shown, the network interface 334 can provide network communication functions and can communicate with the motor of the rotating unit 4; while the user interface 333 is mainly used to provide an input interface for the user; and the processor 331 can be used to call the device control application stored in the memory 335 to realize the semi-automatic marking operation of the laser marking unit 3 on various types of cryopreservation tubes 5.

[0040] It should be understood that in some feasible implementations, the processor 331 described above may be a central processing unit (CPU), or it may be other general-purpose processors, DSPs, ASICs, FPGAs, or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The general-purpose processor may be a microprocessor or any conventional processor. The memory 335 may include read-only memory and random access memory, and provides instructions and data to the processor 331.

[0041] Example 2 like Figures 5 to 8 As shown, based on Embodiment 1, in this Embodiment 2, the marking head 31 is fixedly connected to the first beam transmission tube 32; the carrying unit 2 includes: a second carrying platform 22 detachably disposed on the upper end of the first moving mechanism 13, and a plurality of clamping platforms 23 disposed at equal intervals along the moving direction of the first moving mechanism 13.

[0042] like Figure 7 and Figure 8 As shown, the clamping platform 23 includes: a second support 231, a third support 232, a fourth support 233, a second moving mechanism 234, a first clamping rod 235, a second clamping rod 236, a clamping head 237, and a guide rod 238. The second support 231 is vertically mounted on the upper end of the second support platform 22 and has a bearing adapted to the first clamping rod 235. The second moving mechanism 234 is mounted on the upper end of the second support platform 22, and its axis is collinear with the axis of the second support 231. The third support 232 is mounted on the upper end of the second moving mechanism 234 and has a bearing adapted to the second clamping rod 236. The bearing is aligned with the bearing of the second bracket 231; the fourth bracket 233 is located on one side of the second support platform 22; one end of the guide rod 238 is fixedly connected to the fourth bracket 233, and the other end is located in the guide hole 232a on the third bracket 232, and the end of the guide rod 238 is fixedly connected to the end of the guide hole 232a through an elastic element (not shown in the figure); the first clamping rod 235 and the second clamping rod 236 are provided with a support cavity for accommodating the cryopreservation tube 5 at their respective near ends, and the two clamping heads 237 are respectively symmetrically arranged at the ends of the first clamping rod 235 and the second clamping rod 236 at their respective near ends.

[0043] It is understood that, through the cooperation of the guide rod 238 and the second moving mechanism 234, the distance between the second support 231 and the third support 232 can be conveniently adjusted manually, thereby facilitating the placement operation of the cryopreservation tube 5. At this time, the elastic element is in a compressed state. Subsequently, by releasing the third support 232, the rebound of the elastic element can effectively utilize the first clamping rod 235 and the second clamping rod 236 to stably clamp the cryopreservation tube 5. At this time, the elastic element has not yet fully returned to its natural state, thereby further stabilizing the clamping of the cryopreservation tube 5. It should be noted that in other embodiments, other types of clamping structures can also be used, which are not specifically limited here, but these solutions are all within the protection scope of this utility model.

[0044] In an alternative embodiment, the elastic element may be a compression spring.

[0045] In an optional embodiment, the clamping head 237 is a horn-shaped rubber pad used to stably clamp different types of cryopreservation tubes 5.

[0046] It should be noted that in this embodiment, the second moving mechanism 234 is a guide component commonly used in the prior art, such as a guide rail. Of course, in other embodiments, the second moving mechanism 234 may be other devices, and this utility model does not limit this.

[0047] Furthermore, the rotating unit 4 includes a second motor 43, which is fixedly mounted on one side of the third bracket 232, and its output shaft is connected to the second clamping rod 236 via a transmission component 431. It should be noted that the second motor 43 and the transmission component 431 can effectively drive the second clamping rod 236 to rotate, and simultaneously drive the cryopreservation tube 5 to rotate, thereby ensuring the laser marking range.

[0048] In an optional embodiment, the transmission component 431 includes a gear transmission structure and a belt transmission structure to adapt to different rotation requirements.

[0049] In an optional embodiment, the rotating unit 4 further includes a third motor 44, which is fixedly mounted on one side of the second bracket 231. Its output shaft is connected to the first clamping rod 235, causing the first clamping rod 235 and the second clamping rod 236 to rotate synchronously. This avoids slippage that may occur when a single motor rotates the cryopreservation tube 5, ensuring the rotational stability of the cryopreservation tube 5. It is understood that both the second motor 43 and the third motor 44 maintain a communication connection with the electronic device 33 of the laser marking unit 3, thereby achieving precise marking.

[0050] It should be noted that, through the above design, the marking is performed by rotating the cryopreservation tube 5, which enables continuous scanning and marking of the circumferential surface of the cryopreservation tube by the laser beam without adjusting the position of the marking head. This effectively solves the problem of marking blind spots caused by limited movement or inaccurate positioning of the marking head in traditional equipment, significantly improving the integrity and recognizability of the marking. At the same time, it avoids the instability of the optical path that may be caused by the relative displacement between moving parts, ensuring the efficiency and consistency of laser energy in the transmission process, thereby improving the marking accuracy and clarity, and effectively simplifying the complexity of the optical system and reducing the overall manufacturing and maintenance costs of the equipment.

[0051] Other technical features are the same as in Embodiment 1 and can achieve the same technical effects, so they will not be described in detail here.

[0052] The working principle of this utility model is as follows: In the sample laying area, multiple cryopreservation tubes 5 to be marked are manually placed on the support unit 2, and the cryopreservation tubes 5 are pushed to the laser marking area for marking by the first moving mechanism 13; then, the laser marking unit 3 controls the operation of the first motor 41, or the second motor 43 and the third motor 44, thereby adjusting the rotation of the marking head 31 or the rotation of the cryopreservation tubes 5 to achieve marking at different positions; after all the cryopreservation tubes 5 on the same support platform are marked, the first moving mechanism 13 pushes the cryopreservation tubes 5 out of the laser marking area and replaces the next batch of cryopreservation tubes 5 to be marked, until the marking operation of all the cryopreservation tubes 5 is completed.

[0053] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0054] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0055] In this invention, the terms "comprising," "including," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model, and not to limit it; those skilled in the art will readily understand that the above description is only a preferred embodiment of this utility model, and is not intended to limit this utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
