Description

Technical Field

[0001] This utility model belongs to the field of laboratory storage cabinets, and in particular relates to a laboratory hazardous chemical storage device. Background Technology

[0002] In laboratories, there are many types of experimental reagents, which are frequently purchased and consumed. Some of these reagents are highly hazardous, such as flammable and explosive chemicals, highly toxic chemicals, and strongly corrosive or oxidizing agents. These require storage in dedicated hazardous chemical cabinets, making their safe storage and management increasingly important. Existing hazardous chemical storage cabinets typically use common materials such as PP cabinets or metal cabinets. Common problems include the potential for reagents to be misused, misplaced, or incorrectly located during use. Traditional manual retrieval and placement methods require finding the reagent's location when retrieving it and finding its original position when returning it, which is time-consuming, labor-intensive, inefficient, and prone to errors. Utility Model Content

[0003] The purpose of this utility model is to provide a laboratory hazardous chemical storage cabinet that saves time and effort in storing pharmaceuticals.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A laboratory hazardous chemical storage device includes a cabinet. Storage areas are located on both sides of the cabinet's interior. Multiple storage trays are arranged within each storage area, and storage cavities are evenly distributed on the trays. These cavities are used to hold containers containing hazardous chemicals. A lifting platform is located in the center of the cabinet and is connected to the cabinet via a linear lifting assembly. A collaborative robot is mounted on the lifting platform. A pick-and-place area is located at the bottom of the cabinet, and a positioning device is installed within this area to determine the position of the containers to be stored in the cabinet.

[0006] A further technical solution is that the linear lifting component is a linear module, and a slider is provided on the linear module, and the lifting platform is fixed to the slider.

[0007] A further technical solution is that the positioning device includes an installation hole at the bottom of the cabinet in the pick-up and put-down area, a position sensor is installed in the installation hole, the position sensor is connected to a controller, and the controller is connected to the control switch of the indicator light.

[0008] A further technical solution is that the positioning device includes a base, an outer ring is fixedly mounted on the base, an inner ring is rotatably connected to the inner ring, a plurality of sliding grooves are provided on the outer ring, a support is slidably connected inside the sliding groove, a compression spring is provided inside the sliding groove, one end of the compression spring contacts the support, and the other end contacts the inner sidewall of the sliding groove, a lever is hinged to the support by a pin, the middle part of the lever is rotatably connected to the inner ring by a pin, a slot is opened on the outer ring, an operating rod is fixed on the inner ring, and the operating rod passes through the slot and is slidably connected to it.

[0009] A further technical solution is that the storage cavity is used to place the container, and when the container is in the storage cavity, there is a gap between the container and the storage cavity. An opening is provided at the top of the storage cavity, and the depth of the storage cavity and the diameter of the opening are both less than the height of the container.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0011] By setting up multi-layered storage trays in the storage area inside the cabinet, with storage cavities evenly distributed on the trays, and a lifting platform in the middle of the cabinet connected to the cabinet via a linear lifting assembly, the lifting platform can be driven to rise or fall. A collaborative robot is mounted on the lifting platform, allowing it to move vertically within the cabinet. A retrieval and placement area is located at the bottom of the cabinet, equipped with a positioning device to determine the location of containers to be stored. Since each type of medicine container corresponds to a storage cavity, when retrieving medicine, the collaborative robot's gripper moves to the storage cavity to grasp the medicine container and places it in the retrieval and placement area. Subsequent staff can then retrieve the medicine from the retrieval and placement area. When returning the medicine container, it is placed back on the positioning device in the retrieval and placement area, and the collaborative robot's gripper picks up the container and returns it. This eliminates the process of finding the medicine container when retrieving it and finding its location when returning it. Furthermore, the cabinet height can be set higher, and the storage capacity can be larger. This technical solution saves time and labor, improves work efficiency, and reduces the error rate.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1-9 As shown. A laboratory hazardous chemical storage device includes a cabinet 1. Storage areas 2 are provided on both sides of the cabinet 1. Multiple storage trays 3 are provided within each storage area 2. Receiving cavities 4 are evenly distributed on each storage tray 3. The receiving cavities 4 are used to place containers containing hazardous chemicals. A lifting platform 5 is located in the middle of the cabinet 1. The lifting platform 5 is connected to the cabinet 1 via a linear lifting assembly 6. A collaborative robot 7 is mounted on the lifting platform 5. A pick-and-place area 8 is located at the bottom of the cabinet 1. A positioning device is provided in the pick-and-place area 8 to determine the position of the container to be stored in the cabinet 1. The linear lifting assembly 6 is a linear module with a slider 9. The lifting platform 5 is fixed to the slider 9.

[0023] In use, the linear lifting assembly 6 is an existing linear module, which is driven by a servo motor to rotate a screw. A threaded sleeve is connected to the screw, and a slider 9 is connected to the sleeve and slidably connected to the linear module support 16. The servo motor drives the screw to rotate, which can control the reciprocating movement of the sleeve. The slider 9 is fixed to the lifting platform 5. The base of the collaborative robot 7 is fixed on the lifting platform 5. The gripper of the collaborative robot 7 is at least capable of three-dimensional movement. The linear module can adjust the position of the collaborative robot 7 in the vertical direction, increasing the range of motion of the collaborative robot 7. To pick up a container from the storage tray 3, the collaborative robot 7 moves to the storage tray 3 through the linear module, and then the robotic arm of the collaborative robot 7 extends the gripper above the container and then the gripper descends to pick up the container. The collaborative robot 7, also known as a robotic arm, is an automatic operating device that can imitate certain movements of the human hand and arm to grasp, move objects or operate tools according to a fixed program. This collaborative robot 7 can replace heavy human labor to achieve mechanization and automation of production, and can operate in hazardous environments to protect personal safety. The robot uses the Aobo collaborative robot 7, whose gripper employs a two- or three-jaw gripper structure. During use, the robot's actions—grabbing containers at each storage cavity 4, moving to the pick-and-place area 8, and picking up containers at the positioning device and placing them back into the storage cavity 4—are pre-programmed in the control devices of the collaborative robot 7 and the linear module. This allows users to directly select the desired medicine in the control device, and the collaborative robot 7 can automatically retrieve the corresponding container. Workers can then directly retrieve or place the medicine in the pick-and-place area 8. A weighing sensor is installed inside each storage cavity 4 to obtain the weight of the remaining medicine in the container, which is displayed through the controller and screen. Both the robot and the gripper utilize existing technology. This invention applies the robot to a storage cabinet without modifying the robot or gripper itself.

[0024] The positioning device includes an installation hole 10 at the bottom of the cabinet 1 in the pick-and-place area 8. A position sensor 11 is installed in the installation hole 10. The position sensor 11 is connected to a controller, and the controller is connected to the control switch of the indicator light. Three position sensors 11 are set to accurately locate the position of the container so that the collaborative robot 7 can accurately grasp it. When returning the container, the bottom of the container is triggered by the three position sensors 11. Then, the controller controls the indicator light or buzzer to start to make a prompt, which confirms that the position is accurate. The spacing between the three position sensors 11 should be such that the smallest container can cover it.

[0025] When the container is in the storage cavity 4, there is a gap between the container and the storage cavity 4. The top of the storage cavity 4 has an opening, and both the depth of the storage cavity 4 and the diameter of the opening are smaller than the height of the container. After placing the container (medicine bottle) in the storage cavity 4, even if the medicine bottle being retrieved or other nearby medicine bottles are touched while being retrieved or placed, the medicine bottle will at most tilt within the storage cavity 4, but will not fall over, thus providing protection. Furthermore, the storage cavity 4 can accommodate medicine bottles of various sizes, with few limitations.

[0026] Example 2:

[0027] The positioning device includes a base 12, on which an outer ring 13 is fixedly mounted. An inner ring 14 is rotatably connected to the outer ring 13. The outer ring 13 has multiple sliding grooves 15. A support 16 is slidably connected inside the sliding grooves 15. A compression spring 17 is installed inside the sliding grooves 15. One end of the compression spring 17 contacts the support 16, and the other end contacts the inner wall of the sliding groove 15. A lever 19 is hinged to the support 16 via a pin 18. The middle part of the lever 19 is rotatably connected to the inner ring 14 via a pin 20. A slot 21 is opened on the outer ring 13. An operating rod 22 is fixed on the inner ring 14. The operating rod 22 passes through the slot 21 and is slidably connected to it.

[0028] In use, after placing the container in the inner ring 14, the operating lever 22 is turned to rotate the inner ring 14. As the inner ring 14 rotates, it causes the lever 19 to move, with the free end of lever 19 moving closer to the center of the inner ring 14. The three levers 19 work together to center the container, achieving more accurate positioning. When the inner ring 14 rotates, pin 20 gradually moves closer to pin 18, thus compressing the support 16 and causing the spring 17 to move within the slide groove 15. After releasing the operating lever 22, the spring 17, support 16, and lever 19 simultaneously return to their original positions. This mechanical positioning of the container facilitates precise grasping by the collaborative robot 7.

[0029] The above are merely preferred embodiments of this utility model.
