Description

Technical Field

[0001] The invention belongs to the technical field of automated production lines, and in particular relates to automated cryopreservation tube assembly and coding equipment and a method. Background Art

[0002] The traditional cryopreservation tube assembly and coding process mostly relies on manual operation, which has problems such as low production efficiency, high labor intensity, and difficulty in ensuring product quality. Therefore, the application of automated production line technology in the field of biological experimental consumables production has gradually become a trend in the development of the industry.

[0003] With the rapid development of biotechnology, the demand for biological experimental consumables is growing, especially key consumables such as cryotubes used to preserve biological samples such as cells and tissues, which put forward higher requirements on the quality, safety and information traceability of cryotubes. Therefore, traditional cryotube processing equipment needs to improve its performance and adaptability through technological innovation to meet the needs of the development of modern biotechnology. For example, by adopting laser marking technology, the durability and reliability of cryotube labels can be improved, avoiding the problem of label falling off in low temperature environments. At the same time, by improving the structural design of cryotubes, such as adopting anti-contamination cell cryotube design, the sealing of cryotubes can be improved, sample contamination can be avoided, thereby improving the overall performance and applicability of cryotubes.

[0004] However, traditional equipment relies on manual operation, and production efficiency is affected by many factors such as workers' skill level and work attitude. Traditional production lines often cannot reach the level of automated production lines in terms of production efficiency. Secondly, with the continuous development of automation technology, the introduction of new equipment and systems has put forward higher requirements on the skills of maintenance personnel. Finally, due to relatively low production efficiency and unstable product quality, enterprises often need to invest more time and resources to deal with these problems, thereby increasing production costs.

The trigger mechanism is elastic, and when the telescopic clamp clamps the tube cap, an upward force is applied to the cryopreservation tube in the fixed unit.

[0022] In a preferred embodiment of the present invention, a telescopic member is provided on the second conveyor belt for limiting the displacement of the storage box.

[0023] In a preferred embodiment of the present invention, the shifting mechanism includes a telescopic rod, a rotating shaft rotatably connected to the telescopic rod, and a limiting member fixedly connected to the rotating shaft.

[0024] The present invention also provides an automated cryotube assembly and coding method, comprising the following steps: S1. Prepare the tube body and tube cap that need to be assembled and coded, mark the required coding area on the tube body, and check whether the marking area of ​​all tube bodies is accurate.

[0025] S2, separate the tube body and the tube cap in S1 for loading.

[0029] In a preferred embodiment of the present invention, the number of tube bodies and tube caps assembled each time is limited in step S3, so that the number of assembled cryopreservation tubes is an approximate multiple of the number of tubes that can be stored in the storage box.

[0030] In a preferred embodiment of the present invention, before laser coding the marking area of ​​the qualified cryogenic tube body assembled in S3 in step S4, the relative position of the marking area of ​​each cryogenic tube body and the laser coding machine is adjusted so that all the marking areas are facing the laser coding machine.

[0031] The present invention solves the defects existing in the background technology and has the following beneficial effects: (1) The present invention realizes efficient and accurate assembly and coding through full automation control from the loading of the tube body and the tube cap, to assembly, laser coding, and finally sorting and collection, and also significantly improves product consistency, bringing significant beneficial effects to the large-scale production of cryopreservation tube consumables.

[0032] (2) In the automated cryotube assembly and coding equipment provided by the present invention, a positioning baffle that expands radially outward is arranged on the circumferential side of the bottom of the tube body, a positioning hole is arranged in the fixing unit of the support platform, and a positioning groove that matches the cross-section of the positioning baffle is arranged axially in the positioning hole. The lateral shaking and rotation of the tube body in the fixing unit are limited by physical embedding, thereby improving the stability of the tube body in the storage area, assembly area, laser engraving area and collection area.

[0033] (3) In the automated cryopreservation tube assembly and coding equipment provided by the present invention, the rotary assembly mechanism in the assembly area uses a multi-stage columnar suction nozzle to pick up the tube cap, and a plurality of spherical protrusions are provided on the circumference of the suction nozzle. When picking up the tube cap, the spherical protrusion is tangent to the inner wall of the star-shaped limiter at the top of the tube cap. When the rotary assembly mechanism controls the rotation of the suction nozzle, the spherical protrusion abuts against the inner wall of the star-shaped limiter, driving the tube cap to rotate relative to the tube body and tighten. Compared with the prior art that only relies on negative pressure to rotate the tube cap, the rotation instability caused by uneven negative pressure is reduced, ensuring the tight fit between the tube body and the tube cap.

[0034] (4) In the automated cryopreservation tube assembly and coding equipment provided by the present invention, the telescopic clamp of the sorting mechanism has an arc structure and an elastic limiter that match the curvature of the tube cap. The trigger mechanism is located below the fixed unit and is elastic. The telescopic clamp clamps the tube cap through the arc structure. The trigger mechanism provides an upward force to separate the cryopreservation tube from the fixed unit, solving the problem that the assembled cryopreservation tube cannot be taken out with a suction nozzle. At the same time, the elastic limiter reduces the direct friction and collision between the sorting mechanism and the tube cap, playing a buffering role.

[0035] (5) In the automated cryogenic tube assembly and coding equipment provided by the present invention, the positioning baffle on the side of the tube body is embedded in the positioning groove in the fixing unit, forming a tight fit and precise positioning, effectively preventing the tube body from shaking during rotation, and ensuring the stability of the tube body position; the spherical protrusion on the suction nozzle of the rotating assembly mechanism cooperates with the star-shaped columnar hollow inside the star-shaped limiting part at the top of the tube cap, effectively preventing the tube cap from falling off during suction and rotation, and at the same time reducing the shaking of the tube cap during assembly; through the combination of the above structures, the consistency and accuracy of each cryogenic tube during assembly, coding and collection are ensured, avoiding the problem of inconsistent coding effect due to position deviation.

[0036] (6) In the automated cryogenic tube assembly and coding method provided by the present invention, the coding area is marked on the tube body in advance to ensure that the coding position on each tube body is consistent and correct. Before laser coding the tube body, the relative position of the marked area on each cryogenic tube body and the laser coding machine is adjusted so that all marked areas are facing the laser coding machine, compensating for the positional deviation of the tube body during the transmission and assembly process, thereby improving the consistency of the coding effect.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the invention, unless otherwise specified, "multiple" means two or more.

[0041] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood by specific circumstances.

[0042] In the present invention, the power source and mobile support of the feeding device, the collecting device, and the rotating assembly device can be realized by relying on existing mature technologies, and these power sources include but are not limited to motors, cylinders, hydraulic devices, etc. Since the selection and application of these power sources are already quite mature and common in this field, and are not the core innovation of the present invention, they are not described in detail in the specification of this application.
