Description

Technical Field

[0001] This utility model relates to the field of post-processing equipment technology, specifically to a transfer mechanism and storage device. Background Technology

[0002] In the medical field, samples collected by medical personnel are typically stored in specialized refrigerators for low-temperature preservation. Generally, after post-processing, the sample tubes that have completed testing are automatically transferred from the post-processing equipment to the refrigerator by a transport mechanism, and the samples are placed on storage trays within the refrigerator.

[0003] However, in existing mechanical handling systems, the rotating drum inside the storage refrigerator has a rotation function. During storage operations, the control system needs to drive the rotating drum to rotate and guide the robotic arm to move to the connection port of the storage refrigerator. Due to the weight of the rotating drum itself and the weight of the sample tubes it carries, the rotating drum is under a large load, which can easily lead to significant deformation and rotational positioning deviations. This can cause the sample storage port on the rotating drum to misalign with the connection port, resulting in accidents such as collisions between the robotic arm and the rotating drum, posing a risk of equipment damage and sample contamination. Furthermore, a high-energy-consuming drive motor is required to rotate the drum, making the cost too high.

[0004] In addition, the current robotic arm technology has a short stroke, which makes it difficult to meet the needs of long-distance transportation, limiting the improvement of transportation efficiency and affecting the overall level of automation.

[0005] Therefore, existing technologies need further development. Utility Model Content

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0027] According to an embodiment of this utility model, a transfer mechanism is provided. Please refer to [link / reference]. Figures 1 to 5 The system includes: a support frame 210, the axis of rotation of which extends along a first preset direction; a rotation drive component 220, which is driven to connect with the support frame 210 to drive the support frame 210 to rotate around the axis of rotation; and a transfer assembly 230, which is movably connected to the support frame 210 and is movably arranged along the first preset direction. The transfer assembly 230 includes a transfer component 231 for transferring the material tray 200 and is movably arranged along a second preset direction, wherein the second preset direction is perpendicular to the first preset direction.

[0028] Specifically, the support frame 210 is one of the core components of the entire transfer mechanism. Its rotation axis extends along the first preset direction. When the transfer mechanism is installed inside the storage refrigerator, that is, the support frame 210 extends along the length of the storage refrigerator, allowing the support frame 210 to rotate freely 360 degrees on the horizontal plane, thereby moving to any angle of the storage tray.

[0029] Specifically, the rotation drive component 220 is driven to connect with the support frame 210, and is used to drive the support frame 210 to rotate around the rotation axis, ensuring that the support frame 210 can be precisely adjusted in angle as needed, so that the transfer component 230 can be accurately positioned to the required position.

[0030] Specifically, the transfer component 230 is movably connected to the support frame 210 and is movably set along the first preset direction. The transfer component 231 can also move along the second preset direction (perpendicular to the first preset direction). The transfer component 231 can move in two mutually perpendicular directions, which greatly expands the operating range of the transfer component 230. This not only increases the selectivity of the transfer path, but also enables it to operate flexibly in three-dimensional space.

[0031] In this way, the transfer component 230 can realize three types of movement, including linear movement along a first preset direction, linear movement along a second preset direction (perpendicular to the first preset direction), and rotational movement around the axis of rotation of the support frame. This allows the transfer component 231 to move quickly and accurately to the designated position while maintaining stability. The transfer component 231 can realize multi-dimensional spatial operation, which significantly improves the flexibility and efficiency of material tray 200 transfer. It solves the problem of low transfer efficiency caused by short stroke and inaccurate positioning of the robotic arm in traditional transfer mechanisms, making the transfer process more efficient and accurate, and solving the technical problem of low transfer efficiency of transfer mechanisms in related technologies.

[0032] Applying the transfer mechanism of this embodiment to the post-processing equipment keeps the storage tray (e.g., a rotating basket) for storing samples fixed, enables the transfer component 231 to perform multi-dimensional spatial operations, reduces the risk of collisions between devices, increases the movement stroke of the transfer component 231, and improves the reliability and safety of the system.

[0033] In the transfer mechanism of this embodiment, see Figure 2 The transfer assembly 230 includes: a fixed plate 232, which is movably connected to the support frame 210; and a drive plate 233, which is movably connected to the fixed plate 232. The drive plate 233 is movably arranged along a second preset direction, and a transfer component 231 is mounted on the drive plate 233, which is movably connected to the drive plate 233. With this arrangement, both the transfer component 231 and the drive plate 233 can move along the second preset direction. By controlling the drive plate 233 and the transfer component 231 to move along the second preset direction respectively, the transfer assembly 230 can achieve two-stage extension and retraction, thereby obtaining a longer travel distance.

[0034] In the transfer mechanism of this embodiment, see Figure 2-4 The drive plate 233 is equipped with a first drive motor 2331, and a first drive gear 2332 is mounted on the output shaft of the first drive motor 2331. A first drive rack 2321 meshes with the first drive gear 2332 on the fixed plate 232. The transfer component 231 is equipped with a second drive motor 2311, and a second drive gear 2312 is mounted on the output shaft of the second drive motor 2311. A second drive rack 2333 meshes with the second drive gear 2312 on the drive plate 233. In this way, both the drive plate 233 and the transfer component 231 complete reciprocating movement through a gear and rack structure. Compared with other drive mechanisms such as belts and pulleys used in the prior art, this allows for a greater effective stroke, increases the movement stroke of the robotic arm, and meets the needs of long-distance transfer.

[0035] In the transfer mechanism of this embodiment, see Figure 1-2One end of the transfer component 231 is provided with a support part for transferring the material tray 200. The other end of the transfer component 231 is provided with a clearance groove 2313, which is correspondingly provided with the first drive motor 2331 located on the drive plate 233. The clearance groove 2313 is provided to avoid the first drive motor 2331.

[0036] In the transfer mechanism of this embodiment, see Figure 1 The supporting part includes a positioning element 2314, which protrudes from the transfer component 231 and abuts against a positioning groove on the surface of the material tray 200. Multiple positioning elements 2314 are included. By setting the positioning element 2314, the material tray 200 is suspended in the air. When the transfer component 231 transfers the material tray 200, it inserts under the material tray 200 to lift it up. Simultaneously, the positioning element 2314 can be inserted into the positioning groove on the surface of the material tray 200 for positioning, ensuring the material accuracy of the material tray 200 and preventing the material tray 200 from falling.

[0037] It should be noted that the positioning elements are installed on at least two outer surfaces of the material tray to ensure that the material tray is accurately positioned and to prevent displacement of the material tray.

[0038] In some embodiments, the positioning element is a positioning pin, the support part is a flat plate structure, and the positioning element 2314 protrudes from the support part.

[0039] In the transfer mechanism of this embodiment, see Figure 1 The transfer mechanism includes: a drive rod 240 extending along a first preset direction, the drive rod 240 having an external thread, and the drive rod 240 being threadedly connected to a fixed plate 232; and a lifting drive component, which is drivenly connected to the drive rod 240 to drive the drive rod 240 to rotate. Specifically, the drive rod 240 converts rotational motion into linear motion through the threaded engagement between its external thread and the fixed plate 232, thereby driving the fixed plate 232 and its connected transfer assembly 230 to move up and down along the first preset direction.

[0040] In some embodiments, the lifting drive component includes a lifting drive seat with an internal thread, the lifting drive seat being threadedly connected to the drive rod 240, and a fixing plate 232 being fixedly disposed on the lifting drive seat.

[0041] In some embodiments, the lifting drive component includes a lifting drive motor and a belt. A pulley is mounted on the output shaft of the lifting drive motor, and a pulley is also mounted on the drive rod 240. The belt is connected to the pulleys on the lifting drive motor and the drive rod 240 to drive the drive rod 240 to rotate.

[0042] In the transfer mechanism of this embodiment, see Figure 1 The support frame 210 includes: a first support base 211 and a second support base 212, the first support base 211 and the second support base 212 being spaced apart along a first preset direction; a support rod 213, the two ends of the support rod 213 being connected to the first support base 211 and the second support base 212 respectively, and a drive rod 240 being rotatably mounted on the support rod 213.

[0043] By setting up a first support base 211 and a second support base 212 and arranging them at intervals along a first preset direction (usually the vertical direction or the length direction of the equipment), the overall stability and load-bearing capacity of the support frame can be improved. The drive rod 240 is compactly integrated inside or around the support rod 213, thereby saving space and making the overall structure more compact and efficient.

[0044] In the transfer mechanism of this embodiment, see Figure 5 The support rod 213 includes a first support rod 2131 and a second support rod 2132 arranged opposite to each other. The first support rod 2131 or the second support rod 2132 is hollow inside. A drive rod 240 is installed inside the first support rod 2131 or the second support rod 2132. A moving channel is formed between the first support rod 2131 and the second support rod 2132, and the moving channel accommodates the transfer assembly 230. By using the double support rod design (first support rod 2131 and second support rod 2132), the mechanical strength and stability of the entire support frame can be improved. The moving channel between the first support rod 2131 and the second support rod 2132 provides a passage for the transfer assembly 230 to avoid obstacles and move, making the overall layout more compact.

[0045] In the transfer mechanism of this embodiment, see Figure 1 The rotation drive component 220 includes: a rotation drive motor, on the output shaft of which a first pulley is mounted; a second pulley 221, which is connected to either a first support base 211 or a second support base 212; and a first transmission belt, which is fitted onto the first pulley and the second pulley 221. By using pulleys and a transmission belt for power transmission, a smooth and continuous power transmission process can be achieved, driving the support frame 210 to rotate.

[0046] A storage device, comprising the aforementioned transfer mechanism.

[0047] When the transfer mechanism of this embodiment is applied to storage devices such as storage refrigerators, the transfer component 230 can achieve three types of movement inside the storage refrigerator, including linear movement along a first preset direction, linear movement along a second preset direction (perpendicular to the first preset direction), and rotational movement around the axis of rotation of the support frame. This allows the transfer component 231 to move quickly and accurately to a designated position while maintaining stability. The transfer component 231 can achieve multi-dimensional spatial operation and can flexibly transfer the material tray 200 even when the storage tray is fixed, significantly improving the flexibility and efficiency of transfer. This solves the problem of low transfer efficiency caused by the short stroke of the robotic arm and inaccurate positioning in traditional transfer mechanisms, making the transfer process more efficient and accurate, and solving the technical problem of low transfer efficiency in related technologies.
