Description

Technical Field

[0001] The utility model relates to the technical field of cell culture, and particularly relates to a capping device. Background Art

[0002] Cell therapy is a treatment that uses living cells from patients or donors to replace damaged or diseased cells, stimulate the body's immune response, or regenerate. Stem cells and immune cells are commonly used.

[0003] In the field of cell therapy, the culture of isolated cells is an important process. At present, most of them are manually cultured, which is more dependent on the technical proficiency of operators, etc., and the degree of automation is low. Among them, cell culture flasks are important materials used in the cell culture process for cell growth and proliferation. At present, the opening and capping of cell culture flasks are mainly manually operated and have not been automated. In addition, since cell drug products have high environmental requirements during production, the automated equipment used needs to be able to meet the VHP disinfection requirements and the GMP environmental requirements required during the production process of cell drug products. Summary of the Invention

[0004] An object of the utility model is to provide a sealing assembly that can be used in the production equipment of cell drug products, especially for achieving dynamic sealing of a sealing object.

[0005] A sealing assembly provided by the utility model has more than one sealing groove, and more than one corrugated structure is provided on the sealing groove. The sealing assembly is formed by a flexible material.

[0006] Dynamic sealing refers to a sealing method in which the relative positions of the sealing assembly and the sealing object will have relative movement during the sealing process, where the sealing assembly and / or the sealing object move alone or jointly; compared with static sealing in which the relative positions of the sealing assembly and the sealing object remain fixed during the sealing process, dynamic sealing requires a sealing effect under long-term dynamic action.

[0007] For the sealing assembly of the utility model, the corrugated structure provided on the sealing groove, and at the same time, the sealing assembly is set to be formed by a flexible material. The flexible material can adapt to the deformation and movement of the sealing object within a certain range, maintain a long-term sealing effect, and has high sealing reliability. The corrugated structure can increase the surface area of the sealing assembly, increase the movement range of the sealing object, and the corrugated structure is more likely to adapt to the deformation of the sealing surface during movement, such as surface undulation, deformation, etc., to maintain a good sealing effect, and the corrugated structure can absorb the vibration generated by dynamic movement and reduce its impact on sealing. The corrugated structure is preferably a radial corrugated structure. Radial refers to the direction outward from the center point of the object, perpendicular to the axial direction. When the outer contour of the corrugated structure is circular, the radial direction is the vector direction extending from the center of the circle to any position on the circumference.

[0008] The flexible material of the sealing component in the present utility model refers to a material that can produce obvious elastic deformation under stress and the deformation can return to its original shape, such as silicone rubber material.

[0009] If the sealing component needs to be used under corrosive working conditions, the sealing component is preferably formed of an elastic material with corrosion resistance, such as silicone rubber material.

[0010] As an alternative, since the sealing component is formed of a flexible material, the corrugated structure is formed by bending the upper and lower parts of the sealing groove. After the upper and lower parts of the sealing groove are bent, more than one annular groove and annular protrusion are formed, which is the corrugated structure. The corrugated structure can be a corrugated type or a V-type similar to the corrugated type, etc. Multiple corrugations are preferably concentrically arranged.

[0011] Optionally, more than one through hole is provided on the sealing groove, and the through hole can be used as a fixing hole or an installation hole for the sealed object.

[0012] Preferably, a sealing edge is provided on the sealing component, and a first protrusion is provided on the sealing edge.

[0013] Through the setting of the first protrusion, the sealing performance and fixing performance of the sealing component of the present utility model can be further enhanced. Grooves provided on other structures corresponding to the sealing component, such as the sealed object, or on the fixing structure for fixing the sealing component, cooperate with the first protrusion of the sealing component to further strengthen the sealing effect of the sealing component.

[0014] Preferably, a second protrusion is provided on the outer side of the sealing groove.

[0015] The second protrusion provided on the outer side of the sealing groove can cooperate with the groove provided on the sealed object to increase the sealing effect of the sealed object.

[0016] During the production process of cell drug products, measures should be taken to prevent contamination and cross-contamination as much as possible, meeting the relevant requirements of GMP. That is, the GMP environment is a production environment that conforms to a series of quality management principles and specifications, ensuring the quality and safety of the produced cell products. An object of the present utility model is to provide a capping device.

The rotary clamping driving assembly is connected to the output end of the linear driving assembly, and the linear driving assembly drives the capping component and the rotary clamping driving assembly to achieve linear motion. The linear motion is a horizontal motion or an approximately horizontal motion forming an angle of 0 - 5 degrees with the horizontal direction, which is achieved by setting the output direction of the linear driving assembly to be in the horizontal direction or an approximately horizontal direction forming an angle of 0 - 5 degrees with the horizontal direction. The capping device of the present utility model solves the problem of automatic capping operation for non-vertically placed containers through the above settings and can be used for screwing on or unscrewing operations of containers in the horizontal direction or an approximately horizontal direction forming an angle of 0 - 5 degrees with the horizontal direction.
