Double-track conveying device for pipe cover of frozen pipe

Abstract

The invention relates to the technical field of biomedical devices, and discloses a double-track conveying device for a pipe cover of a frozen pipe. The double-track conveying device comprises a vibration mechanism and a material disc; the material disc is composed of an outer disc part and an inner disc part; a screw conveying plate is arranged on the inner wall of the inner disc part; the screwconveying plate is connected with two first arc conveying tracks; and the first arc conveying tracks are connected with second arc conveying tracks. Each first arc conveying tracks is provided with afirst guide rod; a second arc bottom plate is provided with a first arc hole communicating with the outer disc part; the second arc conveying tracks are connected with third arc conveying tracks; eachthird arc conveying track is provided with a second guide rod, a first lower flange and a second lower flange in sequence; the third arc conveying tracks are connected with fourth arc conveying tracks; and the fourth arc conveying tracks are connected with fifth arc conveying tracks. The double-track conveying device has the characteristics that conveying efficiency is high, labor cost is low andunqualified products are avoided.

Description

technical field [0001] The invention relates to the technical field of biomedical devices, in particular to a dual-track conveying device for cryopreservation tube caps. Background technique [0002] Cryopreservation tube is a disposable medical vessel commonly used in medical and laboratory research to store biological samples. In the era of translational medicine, a large number of biological sample banks began to be built. Personalized diagnosis and precise treatment for each person require biological samples. Long-term ultra-low temperature storage, low temperature storage can keep biological tissues such as blood, stem cells, and immune cells active for a long time. When storing, biological samples need to be submerged in a suitable freezing medium (such as liquid nitrogen). At present, the commonly used containers for storing biological samples are cryopreservation tubes. There are two types of storage tubes. In order to make the cryopreservation tube have good sealin...

AI Technical Summary

Problems solved by technology

[0003] The current cryopreservation tubes are made of polypropylene as raw material. After the tube body and the tube cover are manufactured, preliminary assembly is required, and then the sealing of the assembled cryopreservation tubes is tested in the subsequent process. The initial assembly process of the storage tube is actually to screw the tube cap on the tube body. At present, the initial assembly of the frozen storage tube after production is manual assembly and machine assembly. The disadvantages of manual assembly are obvious, and the labor cost is high. Low efficiency. Compared with manual assembly, machine assembly will be much better in terms of cost, efficiency, and assembly effect. However, in the current assembly process of cryopreservation tubes, the transport efficiency of the tube cap transport machine is low, and it cannot The tube caps are screened to a certain extent, and unqualified tube caps are easily transported to the subsequent process, making the assembly of the tube cap and the tube body in the entire cryotube unqualified, resulting in defective products, and even causing damage to subsequent assembly equipment

[0004] Therefore, the current transportation of cryopreservation tube caps has the problems of low transportation efficiency, high labor costs, and many unqualified products.
