Description

Technical Field

[0001] This utility model relates to the field of cold storage technology, specifically to a biological sample cold storage with a stacking mechanism. Background Technology

[0002] Biological sample cold storage facilities are used to store biological samples. They come in various types and have different characteristics, designed to ensure the quality and activity of biological samples. Biological sample cold storage facilities are typically equipped with refrigeration equipment capable of maintaining a specific temperature range to meet the storage needs of different biological samples. In practical use, biomedical cold storage facilities maintain an internal temperature of -80 degrees Celsius, thus meeting the storage requirements of most biopharmaceutical products. Biological sample cold storage facilities are also equipped with automatic temperature monitoring, display, recording, control, and alarm systems to ensure the stability and safety of the storage environment. These devices achieve fully automatic temperature control through high-precision temperature sensors, requiring no manual operation and greatly improving storage efficiency.

[0003] Cold storage facilities with stacking mechanisms are efficient and automated storage devices specifically designed for storing biological samples. These facilities combine the technological advantages of stacking mechanisms to enable rapid sample access and efficient management.

[0004] A search revealed a utility model patent with publication number CN205187779U, which discloses a stacker crane with a high-speed vertically balanced walking drive mechanism. The crane includes an upper guide rail, a lower guide rail, an upper crossbeam, a lower crossbeam, an upper walking drive mechanism housed within the upper crossbeam, a lower walking drive mechanism housed within the lower crossbeam, and a column connecting the upper and lower crossbeams. The upper walking drive mechanism can move along the upper guide rail, and the lower walking drive mechanism can move along the lower guide rail. At least one guide wheel device is provided on the lower crossbeam. This utility model, through simultaneous upper and lower drive, prevents the stacker crane from tilting, enabling simultaneous operation and stopping, reducing the requirements for the column, and saving manpower, materials, and other resources.

[0005] Although the aforementioned patent uses simultaneous top and bottom driving to prevent the stacker crane from tilting and allows for simultaneous operation and stopping, reducing the requirements for the uprights and saving manpower and material resources, when the stacker crane was used in cold storage, it could not directly place biological samples on the shelves. Staff needed to enter the cold storage to assist the stacker crane. However, staff entering the cold storage needed to wear thick anti-freeze clothing, and they were at risk of frostbite from being in the low-temperature cold storage for a long time.

[0006] Therefore, it is necessary to propose a cold storage for biological samples with a stacking mechanism to solve the above problems. Utility Model Content

[0007] The purpose of this invention is to provide a biological sample cold storage with a stacking mechanism. Through the cooperation of the internal parts of the sample placement mechanism, workers can move biological samples to the bottom of the stacker crane without entering the cold storage. Furthermore, through the cooperation of the internal parts of the sample storage mechanism, biological samples can be retrieved and stored in the storage shelves. This solves the problem in the prior art where, when stacker cranes are used in cold storage, biological samples cannot be directly placed on the shelves, requiring workers to enter the cold storage to assist the stacker crane. Workers entering the cold storage need to wear thick anti-freeze clothing, and there is a risk of frostbite for workers who are in the low-temperature cold storage for a long time.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a biological sample cold storage with a stacking mechanism, comprising a cold storage body, wherein a sample placement mechanism is provided inside the cold storage body and is slidably connected to the interior of the cold storage body, and wherein multiple sample storage mechanisms are provided inside the cold storage body and are located at one end of the sample placement mechanism;

[0009] The sampling mechanism includes a buffer compartment located inside the main body of the cold storage. The buffer compartment is mechanically connected to the main body of the cold storage by multiple sealed doors and is slidably connected inside the main body of the cold storage. A photoelectric sensor is installed and fixed inside the buffer compartment and is located below the sealed doors. A support frame is bolted inside the buffer compartment. A servo motor is fixed to the inner wall of the main body of the cold storage and its output end extends into the interior of the support frame. A threaded rod is rotatably connected inside the support frame and bolted to the output end of the servo motor. A sample platform is slidably sleeved on the top of the support frame and sleeved on the outer wall of the threaded rod and in contact with the photoelectric sensor.

[0010] The sample storage mechanism includes multiple ultra-low temperature storage rooms, which are located inside the main body of the cold storage and at one end of the buffer compartment. Storage racks are bolted to both sides of the inner walls of the multiple ultra-low temperature storage rooms. Stacker cranes are slidably connected inside the ultra-low temperature storage rooms and located between the storage racks.

[0011] Preferably, the sample storage mechanism further includes a connecting bracket, which is mechanically connected to the top of the stacker crane equipment. The bottom end of the connecting bracket is threaded with multiple electric suction cups. The bottom end of the connecting bracket is machined with an arc-shaped limiting block and is slidably connected to the inside of the stacker crane equipment. The top end of the stacker crane equipment is bolted with a drive motor, which is located below the connecting bracket. The output end of the drive motor is bolted with a transmission gear, which rotates inside the stacker crane equipment and is in contact with the surface of the connecting bracket.

[0012] Preferably, the outer wall of the cold storage body is hinged to a storage window, and a control panel is installed and fixed on one side of the window. The inner walls of the buffer compartment and the ultra-low temperature storage compartment are equipped with anti-frost structures, and the photoelectric sensor signal is interconnected with the control panel.

[0013] Preferably, the top of the support frame is provided with a sliding groove that matches the sample platform, and the inner wall of the sample platform is provided with a threaded groove that matches the thread on the outer wall of the threaded rod. The sealed door is slidably connected between the buffer compartment and the cryogenic storage compartment via an electric telescopic rod.

[0014] Preferably, the interior of the cryogenic storage room is provided with a moving space that matches the stacker crane equipment, and the surfaces of the stacker crane equipment and the storage rack are coated with a low-temperature resistant coating. The internal parts of the stacker crane equipment are all electrically driven.

[0015] Preferably, the top of the stacker equipment has an arc-shaped groove that matches the arc-shaped limiting block, the surface of the connecting bracket near the transmission gear has a toothed groove that matches the transmission gear, and the top of the stacker equipment has a rotating groove that matches the connecting bracket.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] 1. Staff open the storage window on the outer wall of the cold storage unit, place the biological sample on the sample platform, close the storage window, and start the servo motor via the control panel. The servo motor drives the threaded rod to rotate, which in turn causes the sample platform to slide stably on the support frame via the thread. This moves the sample on the sample platform to one end of the sealed door to be stored. The photoelectric sensor under the sealed door senses the signal and transmits it to the control panel. The control panel then drives the sealed door to open, thus releasing the seal between the buffer compartment and the ultra-low temperature storage room. This allows the stacker crane to easily retrieve the biological sample from the sample platform into the ultra-low temperature storage room.

[0018] 2. By moving the stacker crane within the cryogenic storage chamber, the connecting bracket is moved through the sealed door to the buffer compartment. An electric suction cup then picks up the biological sample. The stacker crane continues to move, carrying the sample into the cryogenic storage chamber. Simultaneously, the stacker crane itself adjusts its height, adjusting the sample height to match the storage shelf height via the connecting bracket. The drive motor is activated, driving the transmission gears to rotate. These gears, through their grooves, move the connecting bracket, causing it to rotate 90 degrees at the top of the stacker crane via an arc-shaped limit block. This rotation, combined with the electric suction cup, allows the sample to be placed on the storage shelf. This eliminates the need for personnel to manually operate the stacker crane within the main cold storage unit, reducing the risk of prolonged frostbite for workers inside the cryogenic storage chamber.

[0030] The sampling mechanism 2 includes a buffer compartment 201, which is located inside the main body of the cold storage 1.

[0031] The sample storage mechanism 3 includes a cryogenic storage room 301. There are multiple cryogenic storage rooms 301 located inside the main body of the cold storage 1 and at one end of the buffer compartment 201.

The top end of the stacker crane equipment 303 is bolted with a drive motor 307, which is located below the connecting bracket 304. The output end of the drive motor 307 is bolted with a transmission gear 308, which rotates inside the stacker crane equipment 303 and fits against the surface of the connecting bracket 304. The sample storage mechanism 3 utilizes the mutual cooperation between the internal parts.

[0034] Refer to the instruction manual appendix Figure 1-6 The outer wall of the cold storage body 1 is hinged to a storage window, and a control panel is installed and fixed on one side of the window. The inner walls of the buffer compartment 201 and the ultra-low temperature storage room 301 are equipped with anti-condensation structures. The photoelectric sensor 203 signal is connected to the control panel. The storage window is connected to the outer wall of the cold storage body 1 through the hinge, and a control panel is installed and fixed on one side of the window, so that staff can place samples on the sample platform 207 through the storage window.

[0035] Refer to the instruction manual appendix Figure 1-6 The top of the support frame 204 is provided with a sliding groove that matches the sample platform 207, and the inner wall of the sample platform 207 is provided with a threaded groove that matches the thread on the outer wall of the threaded rod 206. The sealed door 202 is slidably connected between the buffer compartment 201 and the cryogenic storage room 301 via an electric telescopic rod. The sealed door 202 is slidably connected between the buffer compartment 201 and the cryogenic storage room 301 via an electric telescopic rod, which facilitates the sealing and isolation between the buffer compartment 201 and the cryogenic storage room 301 by the sealed door 202.

[0036] Refer to the instruction manual appendix Figure 1-6 The cryogenic storage room 301 is equipped with a moving space that matches the stacker crane 303. The surfaces of the stacker crane 303 and the storage rack 302 are coated with a low-temperature resistant coating. The internal parts of the stacker crane 303 are all electrically driven, which facilitates the stable operation of the stacker crane 303 within the cryogenic storage room 301.

[0037] Refer to the instruction manual appendix Figure 1-6The top of the stacker crane 303 is provided with an arc-shaped groove that matches the arc-shaped limiting block 306. The surface of the connecting bracket 304 near the transmission gear 308 is provided with a tooth groove that matches the transmission gear 308. The top of the stacker crane 303 is provided with a rotating groove that matches the connecting bracket 304. The connecting bracket 304 near the transmission gear 308 is provided with a tooth groove that matches the transmission gear 308, and the top of the stacker crane 303 is provided with a rotating groove that matches the connecting bracket 304, which facilitates the connecting bracket 304 to rotate at a 90-degree angle on the stacker crane 303.

[0038] The working principle of this practical application is as follows:

[0039] Refer to the instruction manual appendix Figure 1-6 The staff opens the storage window on the outer wall of the main body of the cold storage 1, places the biological sample on the sample platform 207, closes the storage window, and starts the servo motor 205 through the control panel. The servo motor 205 drives the threaded rod 206 to rotate. The rotation of the threaded rod 206 causes the sample platform 207 to slide stably on the support frame 204 through the thread, so that the sample on the sample platform 207 moves to one end of the sealed door 202 to be stored. The photoelectric sensor 203 under the sealed door 202 senses the signal and transmits the signal to the control panel. The control panel drives the sealed door 202 to open, so that the sealing isolation between the buffer compartment 201 and the ultra-low temperature storage room 301 can be released. This makes it easy for the stacker crane equipment 303 to take the biological sample on the sample platform 207 into the ultra-low temperature storage room 301, so that the biological sample can be stored at a low temperature of -80 degrees Celsius, ensuring the stability and safety of the biological sample storage.

[0040] Refer to the instruction manual appendix Figure 1-6 The stacker crane 303 moves within the cryogenic storage chamber 301, causing the connecting bracket 304 to move through the sealed door 202 into the buffer compartment 201. An electric suction cup 305 then aspirates the biological sample. The stacker crane 303 continues to move, carrying the sample into the cryogenic storage chamber 301. Simultaneously, the stacker crane 303 itself undergoes height adjustment, using the connecting bracket 304 to adjust the sample height relative to the storage rack 302. The drive motor 307 is then activated. The machine 307 drives the transmission gear 308 to rotate. The rotation of the transmission gear 308 drives the connecting bracket 304 to move through the tooth groove. The connecting bracket 304 rotates at a 90-degree angle on the top of the stacker equipment 303 through the arc-shaped limit block 306. The rotation of the connecting bracket 304 can move the sample to the storage shelf 302 through the electric suction cup 305. This eliminates the need for staff to use the stacker equipment 303 inside the cold storage body 1, thus reducing the risk of staff suffering from frostbite at -80 degrees Celsius for a long time inside the ultra-low temperature storage room 301.

[0041] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
