Description

Technical Field

[0001] The utility model relates to the technical field of biological sample freezing equipment, in particular to a conveying device for freezing biological samples. Background Art

[0002] In the biomedical field, biological samples such as blood samples, vaccines, and bacterial and viral strains need to be placed in liquid nitrogen for long-term active preservation. However, in the process of transporting biological samples to the freezing equipment, the biological samples need to be loaded into a test tube box, and then the test tube box is placed in a test tube box loading barrel. The test tube box loading barrel is transported by an AGV cart to transport the test tube box loading barrel to the designated freezing equipment for freezing. In order to prevent staff from directly contacting the test tube box loading barrel, a specific clamping device is required to take out the test tube box containing the biological sample from the test tube box loading barrel. After taking it out, the test tube box needs to be scanned for identification. After the scanning is completed, the test tube box is transferred to the freezing rack, and the freezing rack is placed in the liquid nitrogen tank of the freezing equipment for low-temperature refrigeration. An existing biological sample conveying device is as follows:

[0003] The Chinese patent document with publication number CN110182586A discloses a transfer and conveying device for a test tube rack, which specifically discloses: a rack, a transfer channel arranged on the rack, a discharge platform, a feeding platform, an identification mechanism, a side push mechanism and a conveying mechanism. The discharge platform and the feeding platform are respectively located at the two ends of the transfer channel. The side push mechanism is used to push the test tube rack on the output end of the previous detection process to the discharge platform; the conveying mechanism can convey the test tube rack located at the end away from the feeding platform to the feeding platform via the transfer channel. The above transfer and conveying device uses the identification mechanism to identify the information identification code on the test tube. When the test tube on the test tube rack does not need to enter the next detection process, the side push mechanism pushes the test tube rack to the discharge platform. Conversely, the conveying mechanism conveys the test tube rack to the feeding platform via the transfer channel for use in the detection of the next process.

[0004] However, in the process of transporting the test tube rack (or test tube box) to the feeding platform via the transfer channel by the transport mechanism, it is not stable. The test tube rack (or test tube box) is prone to collision during the transport process, causing the biological sample in the test tube rack (or test tube box) to splash out, thereby posing the risk of biological sample leakage. Therefore, a transport device for freezing biological samples is provided to solve the above technical problems. Utility Model Content

[0025] The following is a detailed description of a transport device for freezing biological samples according to the present invention with reference to the accompanying drawings.

[0026] like Figure 1 As shown, an embodiment of a conveying device for freezing biological samples of the utility model includes a support plate 4 and a support truss 501 arranged on the support plate 4, wherein a horizontal linear module 502 is arranged on the support truss 501, and a vertical linear module 503 is arranged on the horizontal linear module 502, and by running the horizontal linear module 502, the vertical linear module 503 can be made to move back and forth horizontally on the support truss 501. The vertical linear module 503 is provided with a picking mechanism 504 for gripping the test tube box 304. The picking mechanism 504 can move up and down by operating the vertical linear module 503. With the cooperation of the vertical linear module 503 and the horizontal linear module 502, the picking mechanism 504 can freely move vertically and horizontally, so that the picking mechanism 504 can grip the test tube box 304 placed at the specified position (i.e., in the test tube box loading barrel) and transfer the test tube box 304 placed at the specified position to the next mechanism.

[0027] In order to complete the code scanning process of the test tube box 304, a mounting frame 603 is provided on the support plate 4, and a photo recognition camera 604 for scanning the test tube box 304 is installed in the mounting frame 603, and the photo recognition camera 604 is placed at the end of the horizontal moving path of the test tube box 304; after the material picking mechanism 504 clamps the test tube box 304, it runs the horizontal linear module 502 to drive the test tube box 304 to move horizontally, and clamps the test tube box 304 to the top of the photo recognition camera 604 (i.e., the QR code reading position), and the QR code at the bottom of the test tube box 304 is scanned by the photo recognition camera 604 to record the information of the biological sample. In addition, a horizontally arranged conveying module 601 is also provided on the support plate 4, and a pushing module 602 for pushing the test tube box 304 to a specified position (i.e., for placing it on a freezing rack in the liquid nitrogen tank) is provided on the conveying module 601; after the test tube box 304 is scanned, the conveying module 601 is operated to drive the pushing module 602 to be placed directly above the photo recognition camera 604, and then the vertical linear module 503 is operated to drive the test tube box 304 to move downward, so that the test tube box 304 that has completed the code scanning is stably placed on the pushing module 602, and then the conveying module 601 is operated to drive the pushing module 602 to the initial position, so as to bring the test tube box 304 to the specified pushing position, and finally the pushing module 602 is operated to push the test tube box 304 onto the freezing rack, and after multiple test tube boxes 304 are pushed onto the freezing rack, the freezing rack is placed into the liquid nitrogen tank, thereby realizing the freezing and conveying processing of the biological sample.

[0028] The above-mentioned mechanisms and modules arranged on the support plate 4 are all placed in a relatively sealed space, so that the test tube box 304 can be transported in a relatively sealed environment. In order to clamp the test tube box 304 into the relatively sealed space, a feeding port 506 for the test tube box 304 to pass through is provided on the support plate 4, and a sealing cover 505 is placed at the feeding port 506 to cover it. Under the action of the sealing cover 505, the above-mentioned mechanisms and modules are always in a relatively sealed space; a barrel cover placement place 507 for placing the sealing cover 505 is also provided on the support plate 4, and the barrel cover placement place 507 is placed next to the feeding port 506. When the feeding mechanism 504 needs to take materials, the sealing cover 505 placed at the feeding port 506 is first clamped and transported to the barrel cover placement place 507 by the feeding mechanism 504, and then the vertical linear module 503 and the feeding mechanism 504 are reset to the initial position. , by running the vertical linear module 503 to drive the material picking mechanism 504 to move downward, the material picking mechanism 504 passes through the material picking port 506, and clamps the test tube box 304 in the test tube box loading barrel (not shown in the figure) placed at the specified position (the test tube box loading barrel placed at the specified position is connected to the sealed space, so after the sealing cover 505 is separated from the material picking port 506, the test tube box 304 in the test tube box loading barrel is always in a relatively sealed environment), the vertical linear module 503 then drives the material picking mechanism 504 to move upward to bring the test tube box 304 into the relatively sealed space, and finally runs the horizontal linear module 502 to transport the test tube box 304 horizontally to the top of the photo recognition camera 604 for code scanning processing.

[0029] like Figure 2 As shown, the transverse linear module 502 includes a transverse guide rail 5021 installed on the supporting truss 501, and a first sliding seat 5022 is provided on the transverse guide rail 5021, and the first sliding seat 5022 can slide back and forth along the transverse direction on the transverse guide rail 5021, and the vertical linear module 503 is arranged on the first sliding seat 5022; in order to enable the first sliding seat 5022 to slide automatically on the transverse guide rail 5021, a transversely arranged first screw rod 5023 is provided in the transverse guide rail 5021, and the first screw rod 5023 is threadedly connected to the first sliding seat 5022, and a first servo motor 5024 is also installed on the transverse guide rail 5021, and the output shaft of the first servo motor 5024 is transmission-connected to one end of the first screw rod 5023 through a first transmission member 5025. The first servo motor 5024 is started to drive the first lead screw 5023 to rotate through the first transmission member 5025, thereby driving the first sliding seat 5022 to slide back and forth freely on the transverse guide rail 5021, and the first sliding seat 5022 moves back and forth with the vertical linear module 503, the material removal mechanism 504 and the test tube box 304.

[0030] Furthermore, the vertical linear module 503 includes a vertical guide rail 5031 installed on the first sliding seat 5022, and a slider 5032 that can slide up and down is provided on the vertical guide rail 5031, and a lifting frame 5035 is provided on the slider 5032. The material picking mechanism 504 is arranged on the lifting frame 5035. When the slider 5032 slides up and down on the vertical guide rail 5031, the lifting frame 5035 and the material picking mechanism 504 arranged on the lifting frame 5035 can be moved up and down to control the material picking mechanism 504 to be placed at a specified height, so as to clamp the sealing cover 505 to the barrel cover placement 507. After the material picking mechanism 504 is reset, it passes through the material picking port 506 to extend into the loading barrel body, and the material picking mechanism 504 is operated to clamp the test tube box 304 containing the biological sample, and then the slider 5032 is driven to move upward to realize automatic material picking processing.

[0031] In order to drive the slider 5032 to freely move up and down on the vertical guide rail 5031, a second servo motor 5033 with an output shaft facing downward is installed on the top of the vertical guide rail 5031, and a second screw rod 5034 arranged vertically is provided on the output shaft of the second servo motor 5033, and the second screw rod 5034 is threadedly connected with the slider 5032; when it is necessary to control the height of the material taking mechanism 504, the second servo motor 5033 is started, and the second screw rod 5034 is driven to rotate to drive the slider 5032 to freely move up and down on the vertical guide rail 5031. In addition, a vertically arranged guide rod 5036 is fixed on the lifting frame 5035, and the guide rod 5036 is slidably arranged with the vertical guide rail 5031. Under the action of the guide rod 5036, the lifting frame 5035 can be more stable when moving up and down, thereby improving the accuracy of material taking.

[0032] Furthermore, the material taking mechanism 504 includes a clamping cylinder 5041 installed at the bottom end of the lifting frame 5035, and clamping blocks 5042 are provided on both movable ends of the clamping cylinder 5041, and protrusions 5043 for holding the test tube box 304 are provided on the sides where the clamping blocks 5042 on both sides are close to each other. When the clamping cylinder 5041 is operated to control the clamping blocks 5042 to clamp the test tube box 304, the test tube box 304 is driven to move upward and then move horizontally. During the movement, the protrusions 5043 always hold the test tube box 304 to prevent the test tube box 304 from falling during the process of clamping and transporting the test tube box 304, thereby causing leakage of the biological sample. In addition, an elastic anti-slip member 5044 for increasing friction is provided on the side where the clamping blocks 5042 on both sides are close to each other. The elastic anti-slip member 5044 increases the friction between the clamping blocks 5042 and the test tube box 304, further preventing the test tube box 304 from falling during the process of clamping and transporting the test tube box 304. The elastic anti-slip member 5044 can be a silicone strip, a rubber strip, or a PVC plastic strip.

Under the action of the second sliding seat 6012, the pushing module 602 moves back and forth on the conveying rail 6011 to transport the scanned test tube box 304 to the designated pushing position, so that the test tube box 304 is pushed to the freezing rack through the pushing module 602. After a plurality of test tube boxes 304 are placed on the freezing rack, the freezing rack is placed in the liquid nitrogen tank to realize the freezing treatment of the biological sample. In order to drive the second sliding seat 6012 to slide automatically on the conveying guide rail 6011, a third screw rod 6013 whose length direction is consistent with the sliding direction of the second sliding seat 6012 is provided in the conveying guide rail 6011, and the third screw rod 6013 is threadedly connected to the second sliding seat 6012. A third servo motor 6014 is provided at one end of the second sliding seat 6012, and the output shaft of the third servo motor 6014 is fixedly connected to one end of the third screw rod 6013. After the scanned test tube box 304 is placed at the designated position on the pushing module 602, the third servo motor 6014 is started to drive the third screw rod 6013 to rotate, so as to drive the second sliding seat 6012 to slide automatically on the conveying guide rail 6011, and the second sliding seat 6012 moves together with the pushing module 602 to transport the scanned test tube box 304 to the designated pushing position.

[0034] In addition, the pushing module 602 includes a loading frame 6021 fixedly arranged on the second sliding seat 6012 and a first slide rail 6022 arranged on the support plate 4. The length direction of the first slide rail 6022 is consistent with the sliding direction of the second sliding seat 6012. The bottom of the loading frame 6021 is slidably arranged on the first slide rail 6022, so that when the second sliding seat 6012 drives the loading frame 6021 to move, the loading frame 6021 moves more stably; the loading frame 6021 is provided with a test tube box placement place 6023, and a There is a pushing seat 6025 for pushing the test tube box 304 placed on the test tube box placement 6023 away from the loading frame 6021, so as to push the test tube box 304 onto the freezing rack (not shown in the drawing). Specifically, a horizontally arranged second slide rail 6024 is provided on the loading frame 6021, and the length direction of the second slide rail 6024 is perpendicular to the length direction of the first slide rail 6022. The pushing seat 6025 is slidably set on the second slide rail 6024. Under the action of the second slide rail 6024, the pushing seat 6025 can slide freely on the loading frame 6021. In order to drive the pushing seat 6025 to move, a fixed seat 6026 is also provided on the loading frame 6021, and a fourth screw rod 6027 is rotatably provided on the fixed seat 6026, whose axial direction is consistent with the length direction of the second slide rail 6024, and the fourth screw rod 6027 is threadedly connected to the pushing seat 6025; in addition, a fourth servo motor 6028 is installed on the loading frame 6021, and the output shaft of the fourth servo motor 6028 is connected to one end of the fourth screw rod 6027 through a second transmission member 6029; the fourth servo motor 6028 is started, and the fourth screw rod 6027 is driven to rotate through the second transmission member 6029, thereby driving the pushing seat 6025 to automatically slide on the loading frame 6021, thereby automatically pushing the test tube box 304 placed at the test tube box placement 6023 away from the loading frame 6021. In addition, a pair of clearance grooves 60210 for accommodating the clamping blocks 5042 are provided at the test tube box placement 6023; after the test tube box 304 is clamped and delivered to the top of the loading frame 6021 by the clamping claw cylinder 5041, the clamping claw cylinder 5041 is controlled to move downward to extend the clamping blocks 5042 on both ends of the clamping claw cylinder 5041 into the clearance grooves 60210, so that the bottom of the clamped test tube box 304 is in contact with the test tube box placement 6023, Then operate the clamping claw cylinder 5041 to control the clamping block 5042 to release the test tube box 304, so that the test tube box 304 is stably placed in the test tube box placement 6023, and under the action of the yield groove 60210, the test tube box 304 is placed on the loading frame 6021 without collision, preventing the test tube box 304 from falling and colliding with the loading frame 6021 after the clamping block 5042 releases the test tube box 304, thereby improving the stability of biological sample transportation.
