[0026] Combine the following Figure 1-Figure 4 The specific implementation of the sealing and storage device for sterility testing of the utility model is described.

[0027] like Figure 1 As shown, the utility model provides a sealing and preservation device for sterility testing, comprising: a workbench 10, which is arranged in a sterile environment; a sealing mechanism, which is arranged on the workbench 10, and comprises a mechanical arm 20 and a sealing assembly arranged at the end of the mechanical arm 20, wherein the sealing assembly comprises a gun tip transfer device 30 for installing a sealing gun tip; a gun tip buffer rack 40, which is used to receive the sealing gun tip, and the gun tip buffer rack 40 is arranged on the workbench 10 and is located within the operating range of the mechanical arm 20. The device realizes the sample sealing operation under sterile conditions through the above-mentioned integrated automation design, greatly improves the sterility guarantee capability of the detection process, reduces the risk of contamination caused by manual operation, and significantly improves the work efficiency and detection accuracy through the optimization of the automation process, and is particularly suitable for commercial sterility experimental detection occasions with strict requirements on the sterile environment, such as product quality control in the food, beverage and other industries.

[0028] Specifically, the workbench 10 of the sealing storage device is placed in a sterile environment to ensure that all operations are carried out under as sterile conditions as possible to prevent contamination by external microorganisms. The sterile environment may include a sterile laboratory, or a sterile isolation environment created by a workstation hood, etc. The sealing mechanism is arranged on the workbench 10 for performing the sealing operation. The mechanical arm 20 of the sealing mechanism preferably has a high degree of flexibility and precise positioning capability, and can perform complex sealing tasks. The sealing assembly is located at the front end of the mechanical arm 20 and is the specific implementation mechanism of the sealing operation. The gun head transfer device 30 of the sealing assembly can install and operate the sealing gun head to ensure that the sealing process is fast and accurate. The gun head cache rack 40 is located on the workbench 10, close to the operating range of the mechanical arm 20, for temporary storage and management of the sealing gun head. The existence of the gun head cache rack 40 allows the sealing gun head to be properly handled before and after use, ensuring that it is clean and sterile each time it is used, and also facilitates the rapid grasping and replacement of the mechanical arm 20.

[0029] According to the utility model, a sealing and storage device for sterility testing is provided, such as Figure 2 As shown, the gun tip transfer device 30 includes a vertical rod 31, a sleeve 32 and a first driver 33. The vertical rod 31 and the first driver 33 are fixedly arranged relative to each other at the front end of the robot arm 20; the sleeve 32 is sleeved on the vertical rod 31 and cooperates with the first driver 33 in transmission, so as to move along the vertical rod 31 under the drive of the first driver 33. Specifically, the vertical rod 31 and the first driver 33 are arranged at the front end of the robot arm 20, and the two are relatively fixed to form a stable driving foundation, while the sleeve 32 is sleeved on the outside of the vertical rod 31 and can slide up and down along the vertical rod 31. The first driver 33, as a power source, generates a driving force in the vertical direction when it is started, pushing the sleeve 32 to move accurately up and down along the vertical rod 31. The sealing gun tip is squeezed or discharged by the movement of the sleeve 32, and then the sealing operation of the sample container is completed, thereby realizing the automation of the sealing process, avoiding the risk of contamination and inconsistency that may be introduced by manual operation, and improving the sealing efficiency and the sterility of sample preservation. The gun tip transfer device 30 integrates mechanical transmission and automatic control, realizes automatic squeezing and discharge of sealing gun tips, provides reliable support for the sealing and preservation process of sterility testing, and improves the automation level of the entire testing process and the reliability of the test results.

[0030] According to a sealing and preservation device for sterility testing provided by the utility model, a vertical rod 31 and a first driver 33 are arranged in parallel; a detachable connecting plate 34 is arranged between the driving end of the first driver 33 and the sliding sleeve 32. The vertical rod 31 and the first driver 33 are arranged in parallel, which helps to maintain the compactness and stability of the system and also facilitates the direct transmission of the driving force. A detachable connecting plate 34 is arranged between the driving end of the first driver 33 and the sliding sleeve 32, which gives the device higher maintenance convenience and flexibility.

[0031] Specifically, the existence of the connecting plate 34 not only makes the installation and removal of the sliding sleeve 32 easier and faster, and is convenient for daily maintenance or replacement of damaged parts, but also allows for quick adjustment or upgrade of components when necessary without affecting the main structure of the entire device. The detachable nature of the connecting plate 34 means that the connecting plate 34 can be adjusted or customized according to different experimental requirements to accommodate gun tips or packaging materials of different specifications, thereby enhancing the versatility and adaptability of the device.

[0032] According to the utility model, a sealing and storage device for sterility testing is provided, such as Figure 3 As shown, the gun tip transfer device 30 includes a mounting seat 35. The vertical rod 31 is arranged on the mounting seat 35, and at least a part of the vertical rod 31 protrudes downward from the mounting seat 35 for sliding cooperation with the sliding sleeve 32; the first driver 33 is installed on one side of the mounting seat 35. Specifically, the mounting seat 35 of the gun tip transfer device 30 plays the role of supporting and integrating other components. The vertical rod 31 is firmly mounted in the mounting seat 35, extending downward beyond the bottom of the mounting seat 35, forming a sliding cooperation relationship with the sliding sleeve 32, so that the sliding sleeve 32 can move up and down smoothly along the vertical rod 31. The first driver 33 is installed on one side of the mounting seat 35, and the transmission path of the driving force is more direct and efficient. By optimizing the configuration of the moving parts, the flexibility and automation of the sealing operation are significantly improved, providing a more reliable and efficient solution for the sterile preservation of samples during sterility testing.

[0033] According to the utility model, a sealing and storage device for sterility testing is provided, such as Figure 3 and Figure 4 As shown, the sealing mechanism includes a packaging material fixing assembly, and the packaging material fixing assembly includes a second driver 51 and a mounting plate 52. The second driver 51 is installed at the front end of the robot arm 20, and the mounting plate 52 is in transmission cooperation with the second driver 51 to move vertically under the drive of the second driver 51, and the mounting seat 35 is arranged on the mounting plate 52. Through the packaging material fixing assembly, the sealing mechanism can not only perform the sealing operation, but also take into account the fixing and releasing functions of the packaging material, so as to achieve the completion of multiple tasks in the same module, reflecting the efficiency and versatility of the device.

[0034] Specifically, the second driver 51 is connected to the mounting plate 52 through transmission, and can be driven in the vertical direction to move the mounting plate 52 up and down. When sealing operation is required, the second driver 51 presses down the mounting plate 52 to ensure that the sampling packaging material is firmly fixed, providing a stable foundation for the subsequent precise sealing of the sealing gun head. After sealing, the second driver 51 moves again to move the mounting plate 52 upward. This action not only releases the fixation of the packaging material, but also sends a signal to the material transfer robot through the corresponding sensor or control system, instructing it to carry out the next step of material transfer work, forming a smooth automated operation process.

[0035] The first driver 33 and the second driver 51 can select different drive types according to the scene requirements. According to a sealing and preservation device for sterility testing provided by the utility model, the first driver 33 and the second driver 51 are preferably cylinders, and the driving directions of the first driver 33 and the second driver 51 are perpendicular to the workbench 10. Specifically, the first driver 33 and the second driver 51 in the device are both designed as cylinders, which can use the energy of compressed gas to generate linear reciprocating motion. The driving directions of these two cylinders are perpendicular to the workbench 10, so as to provide push and pull forces in the vertical direction, respectively controlling the squeezing and discharge operations of the sealing gun head and the fixing and release of the packaging material.

[0036] According to a sealing and storage device for sterility testing provided by the utility model, the mounting plate 52 is L-shaped, the horizontal portion of the L-shaped mounting plate 52 is arranged at the driving end of the second driver 51, and the mounting seat 35 is detachably mounted on the vertical portion of the mounting plate 52. The horizontal portion of the L-shaped mounting plate 52 serves as a mounting structure matched with the driving end of the second driver 51, and the vertical portion serves as a mounting base for the mounting seat 35 of the gun tip transfer device 30, thereby achieving a compact mounting matching form.

[0037] Further, according to a sealing and preservation device for sterility testing provided by the utility model, the packaging material fixing assembly preferably further includes a driving plate 53; the driving plate 53 is L-shaped, the horizontal portion of the L-shaped driving plate 53 is installed between the horizontal portion of the mounting plate 52 and the driving end of the second driver 51, and a slide rail structure 54 is provided between the vertical portion of the driving plate 53 and the main body of the second driver 51. The L-shaped driving plate 53 not only optimizes space utilization, but also strengthens the ability to work in coordination with the second driver 51.

[0038] Specifically, the horizontal portion of the L-shaped driving plate 53 is installed between the horizontal portion of the mounting plate 52 and the driving end of the second driver 51, and a slide rail structure 54 is added between the vertical portion of the driving plate 53 and the main body of the second driver 51 to support the smooth sliding of the driving plate 53 in the vertical direction to avoid displacement deviation caused by vibration or wear, thereby improving the accuracy and repeatability of the sealing operation.

[0039] According to the utility model, a sealing and storage device for sterility testing is provided, such as Figure 1 As shown, at least one side of the gun tip cache rack 40 is preferably provided with a gun tip holder. The gun tip holder includes a horizontal driver 41 and a limit block 42 provided at the driving end of the horizontal driver 41. The gun tip holder includes a limit state and a release state; in the limit state, the horizontal driver 41 drives the limit block 42 to extend horizontally toward the gun tip cache rack 40 to form a limit fit with the gun tip inner lining plate in the gun tip cache rack 40; in the release state, the horizontal driver 41 drives the limit block 42 to be retracted. The gun tip holder realizes the precise positioning and release of the gun tip inner lining plate, further improving the accuracy and efficiency of the automated operation.

[0040] Specifically, the design of the gun tip cache rack 40 not only takes into account the storage requirements of the sealed gun tips, but also creates a dynamic limit and release mechanism through the gun tip holder set on at least one side. In the limit state, the horizontal driver 41 drives the limit block 42 to extend horizontally and cooperate with the gun tip inner lining plate in the gun tip cache rack 40 to ensure that the gun tip remains stable during storage and transportation to prevent it from falling off or misalignment. When switching to the release state, the horizontal driver 41 retracts the limit block 42 to facilitate the placement of materials.

[0041] The gun tip cache rack 40 can be customized according to the hanging height of the gun tip and the actual size of the inner lining plate, ensuring that the gun tip can be stored safely and appropriately. Multiple groups of chamfered module blocks can be arranged around the top to facilitate the gripping operation of the transfer robot.

[0042] In particular, the gun tip cache rack 40 is preferably provided with at least two groups of gun tip holders located on opposite sides, so that during the material discharge and material retrieval process, precise control of the gun tip inner lining plate can be achieved through their flexible switching between the limiting and releasing states.

[0043] In order to ensure the accuracy of the sealing operation and the continuity of the automated process, according to a sealing storage device for sterile testing provided by the utility model, at least one side of the gun tip cache rack 40 is preferably provided with a photoelectric sensor 43. The detection direction of the photoelectric sensor 43 is toward the gun tip cache rack 40, so as to detect the sealing gun tip in the gun tip cache rack 40. The photoelectric sensor 43 is preferably a diffuse reflection photoelectric sensor 43. When the light beam is emitted from the photoelectric sensor 43 and touches the surface of the target object (i.e., the sealing gun tip), the reflected light will be received by the photoelectric sensor 43. By analyzing the changes in the reflected light, it can be accurately determined whether there is a gun tip in the predetermined position, and then provide an immediate feedback signal. The introduction of the monitoring mechanism enables the system to automatically identify whether the gun tip is ready, thereby ensuring that before the sealing operation, the transfer robot can accurately grasp the sealing gun tip, avoiding the interruption of the operation due to the lack of sealing materials, and improving the continuity and efficiency of the entire automated detection process.

[0044] According to the technical solution of the utility model, the sealing and preservation device meets the requirements of aseptic preservation of samples to be tested, ensuring that a review can be quickly conducted when there are doubts about the test results. It preferably uses a 1000μL large-capacity aseptic plug core gun tip to enhance the sealing of the sample during transportation. The sealing and preservation device avoids the time consumption and resource waste caused by manual intervention in traditional testing, and significantly improves the detection speed and accuracy through a fully automated process. The device almost eliminates the dependence on the technical operation of on-site testing personnel through a highly integrated mechanical and electronic system. The transfer robot and the sealing and preservation device can seamlessly perform sealing and subsequent sample handling through simple signal exchange, ensuring the smooth progress of the sample sealing step in the automated commercial sterile testing workstation, strengthening the rigor of the detection link and the problem tracing capability, not only reducing labor costs, but also promoting a continuous and efficient detection cycle of the workstation.
