Description

Technical Field

[0001] The present invention relates to the field of VHP transfer chambers, and in particular to an automatic sample conveying device for a VHP transfer chamber. Background Art

[0002] The VHP transfer chamber is a device used for biological decontamination of the outer surface of materials. It is mainly used for various clean and dry items that need to be transferred in sterile production, such as outer packaging of packaging materials, instruments, outer packaging of raw and auxiliary materials, accessories, environmental monitoring equipment, etc. This equipment uses hydrogen peroxide vapor (VHPS) as a biological decontaminant and is a decontamination process under low temperature and normal pressure conditions.

[0003] During the operation of the VHP transfer cabin, samples are sent from the low-level area of the VHP transfer cabin into the interior of the VHP transfer cabin, and are taken out from the high-level area after disinfection. In order to avoid mutual infection between the low-level area and the high-level area, the low-level area door and the high-level area door are interlocked to ensure that only one can be opened. The space inside the transfer cabin is limited. Therefore, when a large number of objects need to be transferred, staff are required on both sides of the VHP transfer cabin to alternately open the low-level area door and the high-level area door and place and take out the samples. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an automatic sample delivery device for a VHP transfer chamber.

A transport component, installed above the first support frame, for transporting the sample; Two conveying assemblies are provided on both sides of the VHP transfer cabin body, respectively used for storing and conveying unsterilized and sterilized samples, and used for aligning and connecting with the removed transfer assembly to convey the samples; The staff will place the samples to be transferred on the conveying assembly on the side of the low-level area in turn, and then open the low-level area door. When the low-level area door is opened, the high-level area door remains closed. Then, the limit assembly under the first mobile rack near the low-level area side maintains the card limit on the first mobile rack and the first support rack, while the limit assembly under the first mobile rack near the high-level area side cancels the card limit on the first mobile rack and the first support rack, so that the first support rack moves synchronously with the card limit of the first mobile rack near the low-level area side. After that, the mobile drive is started.

At this time, the conveying component and the transfer component are started, so that the sample placed on the conveying component is transported to the inside of the transfer component, thereby realizing automatic transportation of the sample. After the sample is transported to the top of the transfer component, the mobile driving component is started again, and the mobile driving component drives the first support rack and the first mobile rack near the low-level area.

DETAILED DESCRIPTION

[0029] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0030] like Figures 1 to 11 The VHP transfer chamber sample automated transport device shown includes a VHP transfer chamber body 1, the VHP transfer chamber body 1 includes a transfer chamber 101, the two ends of the transfer chamber 101 are respectively a low-level area 1011 and a high-level area 1012, and the low-level area 1011 and the high-level area 1012 are respectively installed with a low-level area door 102 and a high-level area door 103. The low-level area door 102 and the high-level area door 103 are equipped with an interlocking mechanism. The device also includes: Two first mobile racks 2 are respectively installed inside the transfer cabin 101 through mobile drive components; The first support frame 3 has two ends respectively connected to the two first mobile frames 2 by limiting components. When the first support frame 3 is connected to the corresponding first mobile frame 2 by only the limiting component at one end, the first support frame 3 moves out synchronously with the first mobile frame 2. The transport component is installed above the first support frame 3 and is used to transport the sample; Two conveying assemblies are provided on both sides of the VHP transfer chamber body 1, and are used to store and transport unsterilized and sterilized samples respectively, and are used to align and connect with the removed transfer assembly to transport the samples; During operation, samples are transported from the low-level area of the VHP transfer cabin into the interior of the cabin and taken out from the high-level area after disinfection. To prevent cross-infection between the low-level and high-level areas, the doors of the low-level and high-level areas are interlocked to prevent single-opening. However, the space inside the transfer cabin is limited. Therefore, when a large number of objects need to be transferred, staff are required on both sides of the VHP transfer cabin to alternately open the low-level and high-level area doors and place and remove samples. This embodiment of the present invention can solve the above problems. The specific implementation method is as follows: the staff will place the samples to be transferred on the conveying assembly located on the side of the low-level area 1011 in turn, and then open the low-level area door 102. When the low-level area door 102 is opened, the high-level area door 103 remains closed. Subsequently, the limiting assembly under the first movable rack 2 near the side of the low-level area 1011 maintains the card limit on the first movable rack 2 and the first support rack 3, while the limiting assembly under the first movable rack 2 near the side of the high-level area 1012 cancels the card limit on the first movable rack 2 and the first support rack 3, so that the first support rack 3 passes through the card limit on the first movable rack 2 near the side of the low-level area 1011.

The first movable rack 2 on the side of the level area 1011 is reset, thereby driving the transfer component to reset and drive the transferred sample into the interior of the transfer cabin 101. After the first support rack 3 is reset, the limit component is started to restore the limit of the first movable rack 2 and the first support rack 3, and then the low-level area door 102 is closed, and the sample is disinfected through the VHP transfer cabin body 1. After the disinfection is completed, the high-level area door 103 is opened, and the limit component under the first movable rack 2 near the high-level area 1012 side maintains the card connection limit of the first movable rack 2 and the first support rack 3, and the limit component under the first movable rack 2 near the low-level area 1011 side cancels the card connection limit of the first movable rack 2 and the first support rack 3, so that The mobile driving component drives the first mobile rack 2 near the high-level area 1012 to move toward the high-level area 1012. Similarly, the conveying component of the high-level area 1012 near the high-level area 1012 is aligned with the transfer component, so that the sample is conveyed to the conveying component of the high-level area 1012 near the high-level area to complete the removal of the sterilized sample. By repeating the above steps, a large number of samples can be automatically sterilized and transferred in a cycle, thereby eliminating the need for manual placement and removal of samples by staff, and without interfering with the single opening of the low-level area door 102 and the high-level area door 103 of the VHP transfer cabin body 1, thereby improving the efficiency of sample transportation, eliminating the need for staff settings, and saving labor costs.

Subsequently, the limiting assembly under the first movable rack 2 near the low-level area 1011 side maintains the card limit of the first movable rack 2 and the first support rack 3, while the limiting assembly under the first movable rack 2 near the high-level area 1012 side cancels the card limit of the first movable rack 2 and the first support rack 3, so that the first support rack 3 is synchronized with the card limit of the first movable rack 2 near the low-level area 1011 side. Move, thereafter, start the mobile driving component, and the mobile driving component drives the first mobile rack 2 near the low-level area 1011 side to move toward the low-level area 1011, and the first mobile rack 2 drives the first support rack 3 to move synchronously, thereby driving the conveying component of the first support rack 3 close to the high-level area 1012 side, until the conveying component is aligned with the transfer component on the first support rack 3, at this time start the conveying component and the transfer component, so that the sample placed on the conveying component is transported to the inside of the transfer component, thereby realizing the automatic transportation of the sample, and after the sample is transported to the top of the transfer component, start the mobile driving component again, and the mobile driving component drives the first support rack 3 and the one near the low-level area 1011 The first movable rack 2 on the side is reset, thereby driving the transfer assembly to reset and drive the transferred sample into the interior of the transfer chamber 101.
