Description

Technical Field

[0001] This invention relates to the field of chemical testing equipment, specifically to a multi-channel open-top storage device and method for chemical containers. Background Technology

[0002] As the core container for samples and reagents, the opening of reagent bottles is a fundamental and crucial step in the experimental and testing process. The opening method for reagent bottles on the market is usually manual, which requires operators to manually unscrew or pry open the bottle caps. This is not only labor-intensive and inefficient, but also difficult to meet the needs of large-scale sample processing. To improve efficiency, a multi-channel automated opening device is disclosed in the publication document CN121672384A, which realizes automatic opening. However, the device has certain limitations in use. For example, it lacks measures to manage the removed bottle caps. The device only has a single bottle cap rack to store the removed bottle caps, which means that the device cannot manage multiple bottle caps at the same time. Furthermore, the bottle caps are stored haphazardly, which means that when it is time to put the cap back on, the removed bottle cap cannot be put back on the original bottle. Also, it takes a lot of time to find the corresponding bottle cap for the reagent bottle, which affects the capping efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a multi-channel openable storage device and method for chemical containers, which solves the problem of the lack of existing management measures for removed bottle caps.

[0004] The present invention achieves the above objectives through the following technical solution: a multi-channel open-top storage device for chemical containers, comprising: a base, wherein the base is provided with a support frame for placing reagent bottle racks and a transmission mechanism for driving the support frame to move, and the support frame is provided with a bracket for placing bottle cap racks. The base is equipped with a cap opening mechanism, a cap rack storage mechanism, a cap rack moving mechanism, a detector, and a control device. The detector is used to scan and identify the reagent bottle rack placed on the support frame. The control device is used to control the bottle cap rack moving mechanism to take the corresponding bottle cap rack from the bottle cap rack storage mechanism and place it on the support according to the content identified by the detector, so as to collect the bottle caps. The control device is also used to control the bottle cap rack moving mechanism to move the bottle cap rack containing the bottle caps from the support to the bottle cap rack storage mechanism for storage.

[0005] Preferably, the cap-opening mechanism includes a third mounting frame, a movable frame mounted on the third mounting frame, a third driving component for driving the movable frame to rise and fall, and a cap-tightening unit mounted on the movable frame.

[0006] Preferably, a guide rod is slidably provided on the movable frame, the moving direction of the guide rod is the same as the moving direction of the movable frame, and the guide rod is connected to the capping unit, and an elastic element is provided between the guide rod and the movable frame.

[0007] Preferably, the capping unit includes a rotary motor, an electromagnetic clamping head disposed on the output shaft of the rotary motor, and grippers disposed on the electromagnetic clamping head.

[0008] Preferably, the base is provided with two fixing mechanisms located on both sides of the support frame; The fixing mechanism includes a first mounting frame, a first driving member disposed on the first mounting frame, and a clamping plate disposed on the moving end of the first driving member.

[0009] Preferably, the bottle cap rack storage mechanism includes a second mounting frame, a plurality of brackets arranged sequentially from top to bottom on the side wall of the second mounting frame, and a marking element provided on the brackets, wherein the brackets are used to place the bottle cap rack; The bottle cap holder is provided with a first slot, and the bracket is provided with a first insert for insertion into the first slot.

[0010] Preferably, the bottle cap holder moving mechanism includes a first moving component, a second moving component disposed on the moving end of the first moving component, a storage box disposed on the moving end of the second moving component, a second driving component disposed inside the storage box, and a tray disposed on the moving end of the second driving component. The bottle cap holder is provided with a second slot, and the tray is provided with a second insert for insertion into the second slot.

[0011] Preferably, the bottle cap holder is provided with a first magnetic element, and the tray is provided with a second magnetic element for attracting the first magnetic element.

[0012] Preferably, the tray is provided with a baffle, and the storage box is provided with a photoelectric switch located below the baffle.

[0013] Preferably, a method for storing a chemical container with a multi-channel open lid, utilizing the aforementioned chemical container storage device, includes the following steps: S1: The transmission mechanism drives the support frame to move outward to the base. After placing the reagent bottle rack above the support frame, the transmission mechanism drives the support frame to move in the opposite direction, moving the reagent bottle rack below the capping mechanism. S2: The detector scans and identifies the reagent bottle rack placed on the support frame and transmits the information to the control device. The control device controls the bottle cap rack moving mechanism to take the corresponding bottle cap rack from the bottle cap rack storage mechanism and place it on the support according to the content identified by the detector. S3: After the capping mechanism removes the cap from the reagent bottle, the transmission mechanism drives the support frame to move so that the cap holder on the support is below the capping mechanism to receive the removed cap. S4: After the transmission mechanism drives the support frame to move in the opposite direction and reset, the bottle cap rack moving mechanism moves the bottle cap rack from the support to the bottle cap rack storage mechanism for storage.

[0014] The beneficial effects of this invention are as follows: 1. The reagent bottle rack placed on the support frame is scanned and identified by the detector. Based on the identification result, the control equipment automatically controls the bottle cap rack moving mechanism to retrieve the corresponding bottle cap rack from the bottle cap rack storage mechanism, so that the bottle cap can be accurately placed on the matching bottle cap rack. In the capping operation, the corresponding bottle cap can also be quickly located, so that the original bottle cap is returned to the original bottle, effectively avoiding confusion and improving the overall work efficiency of opening and capping. 2. The bottle cap rack storage mechanism is equipped with multiple trays, allowing for the simultaneous storage of multiple bottle cap racks. This facilitates the categorized storage and management of removed bottle caps. Each tray is identified using markers to ensure that the bottle cap rack moving mechanism does not become confused during the retrieval and placement process. It also allows for quick location of the target bottle cap's storage area, further improving operational efficiency. Furthermore, it supports continuous opening of multiple reagent bottles. Through the above structure and management mechanism, problems such as mixed stacking, cross-contamination, or mismatching of bottle caps during the opening process are effectively prevented, ensuring the cleanliness and traceability of bottle cap management and improving the standardization and reliability of the work process.

Detailed Implementation

[0017] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0018] Example 1

[0019] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 A multi-channel openable storage device for chemical containers includes: a base 1, a transmission mechanism 9 on the top wall of the base 1, the transmission mechanism 9 including two drive wheels, a conveyor belt sleeved on the outer wall of the two drive wheels, and a motor connected to the shaft of one drive wheel. The motor drives one drive wheel to rotate, thereby driving the conveyor belt. A moving block is provided on the conveyor belt, and a support frame 3 is provided on the top wall of the moving block. One side of the top of the support frame 3 is used to place a reagent bottle rack 10, and a bracket 8 is provided on the other side of the top wall of the support frame 3. The top of the bracket 8 is used to place a bottle cap rack 603. The top wall of the base 1 is provided with an opening mechanism 5, a bottle cap rack storage mechanism 6, a bottle cap rack moving mechanism 7, a detector 11 (specifically a scanner, which can be a barcode scanner or barcode reader) and a control device 12 (such as a PLC controller).

[0020] A multi-channel open-top storage method for chemical containers includes the following steps: First: The transmission mechanism 9 drives the support frame 3 to move outward to the base 1, and after placing the reagent bottle rack 10 above the support frame 3 (the external robotic arm holds the reagent bottle rack 10 and drives the reagent bottle rack 10 to move above the support frame 3), the transmission mechanism 9 drives the support frame 3 to move in the opposite direction, and moves the reagent bottle rack 10 directly below the cap opening mechanism 5. Second: The detector 11 scans the QR code on the reagent bottle rack 10 placed on the support frame 3 and transmits the information to the control device 12 for recording. The control device 12 controls the bottle cap rack moving mechanism 7 to take the corresponding bottle cap rack 603 from the bottle cap rack storage mechanism 6 and place it on the bracket 8 according to the content identified by the detector 11. Third: After the capping mechanism 5 removes the cap from the reagent bottle, the transmission mechanism 9 drives the support frame 3 to move outward from the base 1, so that the cap holder 603 on the bracket 8 is below the capping mechanism 5 to receive the removed cap; when the cap holder 603 is directly below the capping mechanism 5, the reagent bottle rack 10 is outside the base 1. At this time, the external robotic arm can remove the reagent bottle rack 10 from the bracket 8 and place other unopened reagent bottle racks 10 (this step can be selected according to whether there is a need for continuous capping) so that the capping work can be carried out continuously. Fourth: After the bottle cap is placed on top of the bottle cap rack 603, the transmission mechanism 9 drives the support frame 3 to move in the opposite direction to reset. Then, under the control of the control device 12, the bottle cap rack moving mechanism 7 moves the bottle cap rack 603 from the bracket 8 to the bottle cap rack storage mechanism 6 for storage.

[0021] The specific steps for sealing multi-channel chemical containers are as follows: First: The transmission mechanism 9 drives the support frame 3 to move outward from the base 1, and after placing the reagent bottle rack 10 (the reagent bottles stored in the reagent bottle rack 10 have had their caps removed) above the support frame 3, the transmission mechanism 9 drives the support frame 3 to move in the opposite direction. Second: The detector 11 scans and identifies the reagent bottle rack 10 and transmits the information to the control device 12 to check whether the bottle cap rack storage mechanism 6 contains the corresponding bottle cap of the reagent bottle. If not, the subsequent work stops. If it does, the control device 12 controls the bottle cap rack moving mechanism 7 to take the corresponding bottle cap rack 603 from the bottle cap rack storage mechanism 6 and place it on the bracket 8. Third: The transmission mechanism 9 drives the support frame 3 to move outward to the base 1, so that the bottle cap rack 603 on the bracket 8 is below the cap opening mechanism 5. After the cap opening mechanism 5 picks up the bottle cap from the bottle cap rack 603, the transmission mechanism 9 drives the support frame 3 to move in the opposite direction, moving the reagent bottle rack 10 directly below the cap opening mechanism 5. Fourth: The cap opening mechanism 5 installs the cap onto the reagent bottle, while the control device 12 controls the cap holder moving mechanism 7 to move the cap holder 603 from the support 8 to the cap holder storage mechanism 6 for storage. The transmission mechanism 9 drives the support frame 3 to move outward from the base 1, removing the reagent bottle holder 10 from the support frame 3.

[0022] It should be noted that the top wall of the base 1 is provided with a shell 2, which is used to cover the device installed on the top of the base 1. An opening is provided on the side wall of the shell 2, allowing the end of the support frame 3 to move outward from the base 1, so that the reagent bottle rack 10 can be placed on the support frame 3, or the reagent bottle rack 10 can be removed from the support frame 3.

[0023] In this embodiment, as a further optimization, please refer to... Figure 2 and Figure 9 The cover opening mechanism 5 includes a third mounting frame 501 mounted on the top wall of the base 1, a movable frame 502 slidably mounted on the side wall of the third mounting frame 501 (the movable frame 502 can move up and down), a third driving component 503 mounted on the side wall of the third mounting frame 501, and a cover tightening unit 504 mounted on the movable frame 502. The third driving component 503 can be a cylinder, an electric telescopic rod, or a motor, a lead screw mounted on the output shaft of the motor, and a sliding sleeve mounted on the outer wall of the lead screw (the sliding sleeve is connected to the movable frame 502), used to drive the movable frame 502 to rise and fall. Please refer to Figure 9 and Figure 10The capping unit 504 includes a rotary motor 5041, an electromagnetic clamping head 5042 mounted on the output shaft of the rotary motor 5041, and grippers 5043 mounted on the electromagnetic clamping head 5042. The electromagnetic clamping head 5042 uses a miniature electromagnet; when energized, it generates magnetic force to drive the grippers 5043 to close inwards, and when de-energized, it releases. A third driving component 503 drives the moving frame 502 to move downwards, positioning the grippers 5043 on the side of the bottle cap. Then, the electromagnetic clamping head 5042 is energized, causing the grippers 5043 to close inwards and adhere to the side wall of the bottle cap, clamping it. Next, the rotary motor 5041 drives the electromagnetic clamping head 5042 and grippers 5043 to rotate, while the third driving component 503 drives the moving frame 502, along with the rotary motor 5041 and grippers 5043, to move upwards, thereby removing the bottle cap from the test... The reagent bottle is removed; during the capping process, the third drive 503 drives the moving frame 502 to move downward, so that the gripper 5043 is on the side of the cap holder 603 where the cap is placed. Then, the electromagnetic gripping head 5042 is energized, so that the gripper 5043 moves inward and fits against the side wall of the cap to clamp it. After clamping the cap, the third drive 503 drives the moving frame 502 to move upward with the cap. After the cap is moved above the reagent bottle, the third drive 503 drives the moving frame 502 to move downward with the cap, so that the cap is inserted into the mouth of the reagent bottle. At the same time, the rotating motor 5041 drives the electromagnetic gripping head 5042 and the gripper 5043 to rotate, tightening the cap. After the capping is completed, the electromagnetic gripping head 5042 drives the gripper 5043 to release the cap. Then, the third drive 503 drives the moving frame 502 to move upward with the cap.

[0024] It should be noted that multiple capping units 504 are installed on the mobile frame 502, so that the capping mechanism 5 can simultaneously open or cap multiple reagent bottles.

[0025] In this embodiment, as a further optimization, please refer to... Figure 9 and Figure 10 A guide rod 506 is slidably mounted on the movable frame 502. The direction of movement of the guide rod 506 is the same as that of the movable frame 502. The guide rod 506 is connected to the capping unit 504. An elastic element 505 (spring) is provided between the guide rod 506 and the movable frame 502. As the guide rod 506 moves up and down at the movable frame 502 and the elastic element 505 extends and retracts, the pressure exerted on the capping unit 504 when it comes into contact with the reagent bottle is not too great, thus achieving a compensation and buffering effect.

[0026] In this embodiment, as a further optimization, please refer to... Figure 3 and Figure 4 Two fixing mechanisms 4 are provided on the top wall of the base 1, and the two fixing mechanisms 4 are located on both sides of the support frame 3 respectively; The fixing mechanism 4 includes a first mounting frame 401, a first driving member 402 (such as a cylinder) mounted on the first mounting frame 401, and a clamping plate 403 mounted on the moving end of the first driving member 402. The first driving member 402 drives the clamping plate 403 to move closer to the support frame 3 and contact the reagent bottles on the reagent bottle rack 10 to fix the reagent bottles so that the reagent bottles will not move when the cap is opened or closed.

[0027] Example 2

[0028] As a further optimization of Example 1, please refer to Figure 2 , Figure 5 and Figure 6 The bottle cap rack storage mechanism 6 includes a second mounting bracket 601 mounted on the top wall of the base 1, several brackets 602 arranged sequentially from top to bottom on the side walls of the second mounting bracket 601, and a marking element 605 (such as an electronic price tag, used to number each bracket 602) on the brackets 602. The top wall of the bracket 602 is used to place the bottle cap rack 603. A first slot 606 is provided on the bottom wall of the bottle cap rack 603, and a first insert 607 is provided on the top wall of the bracket 602. The first insert 607 is inserted into the inner cavity of the first slot 606, fixing the bottle cap rack 603 above the bracket 602 so that it will not move arbitrarily and fall off. The marking element 605 is used to identify the bracket 602 so that the bottle cap rack moving mechanism 7 will not make mistakes when picking up the bottle cap rack 603 (the bottle cap corresponds to the bottle cap rack 603 used to store the bottle cap), and at the same time, it can quickly find the storage area of ​​the bottle cap, improving the efficiency of opening and closing the cap.

[0029] In this embodiment, as a further optimization, please refer to... Figure 2 , Figure 5 , Figure 7 and Figure 8The bottle cap holder moving mechanism 7 includes a first moving member 701, a second moving member 702 disposed on the moving end of the first moving member 701, a storage box 703 disposed on the moving end of the second moving member 702, a second driving member 706 (such as a cylinder) disposed inside the storage box 703, and a tray 704 disposed on the moving end of the second driving member 706. The first moving member 701 and the second moving member 702 can be servo slides. The first moving member 701 is used to move the second moving member 702 horizontally, and the second moving member 702 is used to move the storage box 703 up and down, moving the storage box 703 below a tray 602. Then, the second driving member 706 drives the tray 704 to move upward and contact the bottom of the bottle cap holder 603, lifting the bottle cap holder 603 and separating it from the tray 602. Then, the first moving member 701... The bottle cap holder 603 is removed from the bracket 602 by moving the second moving part 701 and the second moving part 702 (after the first moving part 701 and the second moving part 702 move the storage box 703 to a position below the bracket 602, and the bottle cap holder 603 above the tray 704 is directly above the bracket 602, the second driving part 706 drives the tray 704 to move down, so that the bottle cap holder 603 contacts the top of the bracket 602, thus completing the placement of the bottle cap holder 603); a second slot 608 is provided on the bottom wall of the bottle cap holder 603, and a second insert 707 is provided on the top wall of the tray 704. When the top of the tray 704 contacts the bottom of the bottle cap holder 603, the second insert 707 is inserted into the second slot 608 to position the bottle cap holder 603 so that it will not move easily above the tray 704 and avoid falling off.

[0030] In this embodiment, as a further optimization, please refer to... Figure 8 The bottle cap holder 603 has a first magnetic element 604 on its bottom wall and a second magnetic element 705 on its top wall. The first magnetic element 604 and the second magnetic element 705 are magnetic blocks, and the bottom magnetic pole of the first magnetic element 604 is opposite to the top magnetic pole of the second magnetic element 705. When the tray 704 holds the bottle cap holder 603, the first magnetic element 604 and the second magnetic element 705 are in contact and attract each other, fixing the bottle cap holder 603 to the top of the tray 704. Even if the bottle caps are unevenly placed on the top of the bottle cap holder 603, causing uneven force on both sides of the bottle cap holder 603, the bottle cap holder 603 will not tip over, ensuring the stability of the tray 704 when picking up the bottle cap holder 603.

[0031] In this embodiment, as a further optimization, please refer to... Figure 8The tray 704 is provided with a baffle 709, and the storage box 703 is provided with a photoelectric switch 708. The photoelectric switch 708 is located below the baffle 709. When the second drive member 706 moves the tray 704 downward, the baffle 709 moves along with it. When the baffle 709 covers the photoelectric switch 708, the second drive member 706 stops working and is used to control the downward position of the tray 704.

[0032] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
