Description

Technical Field

[0001] This utility model belongs to the field of chemical experimental technology, and in particular relates to a safe management storage cabinet. Background Technology

[0002] Safety management storage cabinets for chemical laboratories are core equipment for the standardized storage of hazardous chemicals in laboratories. They need to be suitable for the zoned storage of corrosive chemicals (such as acids and alkalis), flammable liquids (flash point <60℃), and toxic reagents. Based on the characteristics of the stored materials, a three-level labeling system is used: yellow (flammable), red (corrosive), and blue (toxic). Typical application scenarios include university chemistry laboratories, pharmaceutical R&D centers, and industrial quality inspection departments, effectively reducing the risks of fire, leakage, and cross-contamination.

[0003] Comparing with Chinese Patent CN220900446U, a safety management storage cabinet for chemical experiments is disclosed, including a cabinet body, a placement board, and an air exchange box. The cabinet body has a door on the front, and the placement board inside the cabinet has a fixing mechanism. A detection component is located on the back of the cabinet's interior. The air exchange box is fixedly connected to the top of the cabinet, and the air exchange box has an anti-clogging mechanism. An alarm light is fixedly connected to the front of the air exchange box. During heat dissipation, a fan inside the air exchange box draws in air, and the impeller drives a rotating rod to rotate. The rotating rod drives a cleaning rod to clean the filter screen, preventing clogging. This solves the problem that impurities are easily drawn into the air inlet of the air exchange box and the filter screen easily becomes clogged during heat dissipation.

[0004] However, the aforementioned patent requires the cabinet door to be fully opened and closed regardless of the chemical reagent being taken out or put in, which increases the risk of collision with other chemical reagents and reduces the convenience of operation. Therefore, a new device needs to be designed. Utility Model Content

[0005] The purpose of this invention is to provide a secure storage cabinet to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A safe storage cabinet includes a cabinet assembly for independently storing chemical reagents. The cabinet assembly contains a moving device for positioning and a retrieval device for inserting and placing chemical reagents. The cabinet assembly includes a cabinet body with an access component at the front for enhanced safety, allowing for the individual entry and exit of chemical reagents. Several storage slots are evenly distributed on the rear wall of the cabinet body, each containing a reagent rack. The moving device includes a moving frame with two first linear motors symmetrically mounted at its bottom. A first linear guide rail is positioned between the first linear motors, and a lifting component for vertical movement is located within the moving frame. The retrieval device includes a reciprocating selection component with a swing motor mounted on it. An insertion / removal bracket is mounted at the output end of the swing motor.

[0008] Furthermore: the access component includes a front cover plate, a fireproof glass plate is installed in the middle of the front cover plate, and an access window is installed on the fireproof glass plate.

[0009] Furthermore: the bottom of the reagent rack is provided with an insertion slot, and the top of the reagent rack is provided with a limiting slot.

[0010] Furthermore, the lifting assembly includes two symmetrically arranged second linear guide rails, on which a second linear motor is mounted, and a lifting frame is installed between the second linear motors.

[0011] Furthermore: the first linear guide rail is fixedly installed on the bottom surface of the cabinet, and the second linear guide rail is vertically installed on both sides of the movable frame.

[0012] Furthermore: the selection component includes a horizontally arranged third linear guide rail, a third linear motor is mounted on the third linear guide rail, a translation frame is mounted on the third linear motor, and a swing motor is mounted at the rear end of the translation frame.

[0013] Furthermore, the insertion rack is L-shaped, and its horizontal length is greater than the horizontal depth of the storage tank.

[0014] Compared with existing technologies, the beneficial effects are:

[0015] 1. By placing chemical reagents independently and accessing them through a unified access window, the risk of frequent opening and closing of cabinet doors is reduced, thus improving the safe storage of chemicals such as explosive, highly toxic, or volatile chemicals.

[0016] 2. A three-axis linear motor drive (first, second, and third linear motors) combined with a guide rail system enables horizontal movement (X-axis), vertical lifting (Z-axis), and front-to-back positioning (Y-axis) of the reagent rack, accurately aligning it with the target storage slot; a swing motor controls the rotation of the L-shaped insert rack to ensure that the reagent rack is parallel to the inlet / outlet window, simplifying the retrieval and placement process; the automated device replaces manual searching, shortening reagent positioning time, and is especially suitable for the management of large batches or high-risk reagents;

[0017] 3. The storage slots evenly distributed on the rear wall of the cabinet, combined with movable reagent racks, maximize the use of the cabinet space; the horizontal length of the rack is greater than the depth of the storage slot, ensuring that the reagent rack can only be removed after it is fully inserted, preventing accidental movement when not secured; it is significantly superior to traditional storage cabinets in terms of safety, operational efficiency and space utilization, and is especially suitable for professional fields with strict requirements for chemical management.

The access component includes a front cover plate 102, and an explosion-proof glass 103 is installed in the middle of the front cover plate 102. An access window 104 is installed on the explosion-proof glass 103. An insertion slot 107 is provided at the bottom of the reagent rack 106, and a limiting slot 108 is provided at the top of the reagent rack 106. Chemical reagents are placed in the limiting slot 108 of the reagent rack 106 and stored individually in the cabinet body 101 through the storage slots 105. The explosion-proof glass 103 facilitates viewing and selection. The insertion rack 305 is inserted into the insertion slot 107 at the bottom of the reagent rack 106. The reagent rack 106 is moved to the access window 104, and the access window 104 is opened to retrieve and place chemical reagents.

[0028] In this embodiment: the moving device includes a moving frame 201, with two first linear motors 203 symmetrically mounted on the bottom of the moving frame 201. A first linear guide rail 202 is provided between the first linear motors 203. A lifting assembly for vertical movement is provided inside the moving frame 201. The lifting assembly includes two symmetrically arranged second linear guide rails 204, with a second linear motor 205 mounted on the second linear guide rails 204. A lifting frame 206 is installed between the second linear motors 205. The first linear guide rails 202 are fixedly installed on the bottom surface of the cabinet body 101, and the second linear guide rails 204 are vertically installed on both sides of the moving frame 201. The first linear motors 203 drive the moving frame 201 to move along the first linear guide rails 202, so that the insertion rack 305 is inserted into the insertion slot 107 at the bottom of the reagent rack 106 in the limiting slot 108. The second linear motors 205 drive the lifting frame 206 to move up and down along the second linear guide rails 204 on the moving frame 201 for positioning.

[0029] In this embodiment: the pick-and-place device includes a selection component for reciprocating movement, a swing motor 304 is mounted on the selection component, and an insertion frame 305 is mounted on the output end of the swing motor 304; the selection component includes a horizontally arranged third linear guide rail 301, a third linear motor 302 is mounted on the third linear guide rail 301, a translation frame 303 is mounted on the third linear motor 302, and the swing motor 304 is mounted at the rear end of the translation frame 303; the insertion frame 305 is L-shaped, and its horizontal length is greater than the horizontal depth of the storage tank 105; the third linear motor 302 drives the translation frame 303 to move along the third linear guide rail 301 on the lifting frame 206, so that the insertion frame 305 is aligned with the pick-and-place position, and the insertion frame 305 is inserted into the insertion slot 107 at the bottom of the reagent rack 106. The translation frame 303 supports the swing motor 304 to rotate the insertion frame 305 horizontally, which facilitates pick-and-place.

[0030] Working principle: When retrieving chemical reagents stored in cabinet 101, the second linear motor 205 first drives the lifting frame 206 to move up and down along the second linear guide rail 204 on the moving frame 201. The third linear motor 302 drives the translation frame 303 to move along the third linear guide rail 301 on the lifting frame 206, so that the insertion rack 305 is aligned with the reagent rack 106 to be retrieved. Then, the first linear motor 203 drives the moving frame 201 to move along the first linear guide rail 202, so that the insertion rack 305 is inserted into the insertion slot 107 at the bottom of the reagent rack 106 in the limiting groove 108. Then, the second linear motor 205... 5. Then, the insertion rack 305 is slightly raised, causing the reagent rack 106 to detach from the bottom of the storage tank 105. The first linear motor 203 then drives the insertion rack 305 to move outward, moving the reagent rack 106 out of the storage tank 105. Next, the translation rack 303 supports the swing motor 304 to rotate the insertion rack 305 horizontally to the side at a 90-degree angle, parallel to the explosion-proof glass 103. Following the above moving steps, the reagent rack 106 is moved to the inlet / outlet window 104. The inlet / outlet window 104 is opened, and the chemical reagent can be taken out from the limiting groove 108 of the reagent rack 106. To put in the chemical reagent, the above steps are reversed.
