Description

Technical Field

[0001] The invention relates to the technical field of magnetic stirrers, in particular to an automatic magnetic material taking device. Background Art

[0002] Magnetic stirrers are often used together with magnetic stirrers, mainly for stirring or heating low-viscosity liquids. The principle is to use the magnetic field to drive the magnetic stirrer in the container to move, thereby stirring the liquid. Combined with a temperature control system, the heating temperature can be adjusted according to experimental requirements to ensure that the liquid mixing achieves the desired effect.

[0003] The combination of magnets and magnetic stirrers often appears in the scene of drug preparation. For example, in the process of preparing perovskite precursor solution, the purpose is to fully dissolve methylamine iodide and formamidine chloride in the organic solution dimethylformamide and dimethyl sulfoxide. Due to the instability of drugs, the preparation process is usually carried out in a glove box under a closed inert atmosphere. When adding magnets to the container in the glove box, the experimental results may not meet expectations due to factors such as difficult operation and easy contamination of other drug particles. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention proposes an automatic magnetic particle taking device, which automatically adds magnetic particles and is not easily contaminated by drug particles in the glove box during the adding process of the magnetic particles.

[0008] Preferably, a top cover is provided on the top of the storage bin. The top cover prevents the drug particles in the glove box from entering the storage bin during the circulating air washing process and contaminating the magnet. The top cover covers the top of the storage bin to form a sealed isolation to prevent foreign particles or impurities from falling into the storage bin, thereby ensuring the cleanliness of the magnet and the accuracy of the material distribution operation.

[0009] Preferably, the bottom of the stepper motor is mounted on a mounting column, and the outer shell is provided with a notch for mounting the stepper motor. In the above technical solution, a stable installation of the stepper motor is provided, and the compact structure and maintenance of the device are facilitated. It is ensured that the output end of the stepper motor can be docked with the rotating shaft, which facilitates the layout and installation of the overall device.

[0010] Preferably, the output end of the stepper motor is fixedly connected to one end of the rotating shaft, and the other end of the rotating shaft is fixedly connected to the center of the rotating material distribution disk. In the above technical solution, the precise rotation of the material distribution disk is achieved by transmitting the power of the stepper motor to the rotating material distribution disk. The stepper motor is connected to the rotating shaft through the output end, and the rotational power is transmitted to the center of the rotating material distribution disk, driving the material distribution disk to rotate precisely at a set angle, thereby realizing the material distribution and discharge functions of the magnet.

[0011] Preferably, the base is provided with a start switch for controlling the power supply of the stepper motor and the electromagnetic coil.

[0012] Preferably, the notch of the buffer slot is provided with an arc-shaped notch. The arc-shaped notch guides the magnet to smoothly enter the discharge channel to avoid jamming or retention. The arc-shaped notch provides a larger fault tolerance space, guides the magnet to smoothly slide into the discharge channel during the rotation of the distribution disc, and reduces friction during movement.

[0013] Preferably, the buffer groove is formed by extending from the radial outer wall of the rotating material distribution disk toward the center.

[0014] Preferably, the inner diameters of the material distribution channel, through hole, buffer tank and discharge channel are the same. In the above technical solution, the smooth flow of the magnetic particles in the entire material distribution and discharge process is guaranteed to prevent jamming or blockage. The same inner diameter design ensures that when the magnetic particles enter the buffer tank from the through hole and then to the discharge channel, they will not be retained or blocked due to changes in channel size, thereby improving the stability and reliability of equipment operation.

[0015] The present invention has the following characteristics and beneficial effects:

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0025] The present invention provides a magnetic automatic material taking device, such as Figure 1-Figure 3 As shown, it includes a mounting mechanism and a material storage mechanism and a material distribution mechanism installed on the mounting mechanism.

[0026] Specifically, the material storage mechanism includes a material storage bin 2, the bottom of the material storage bin 2 is a funnel-shaped structure, a material distribution opening is provided at the center of the bottom of the material storage bin 2, the material distribution opening extends downward to form a material distribution channel 9, the material distribution channel 9 is made of metal material, and the outer wall of the material distribution channel 9 is sleeved with an electromagnetic coil 3. It can be understood that by passing the electromagnetic coil 3, a magnetic field is generated, and the magnetic particles in the material storage bin 2 are loaded into the material distribution mechanism under the action of the magnetic field, thereby completing the subsequent material distribution operation.

[0027] A further configuration of the present invention is that the material distributing mechanism includes a stepper motor 8, a fixed material distributing disk 6 and a rotating material distributing disk 4, the fixed material distributing disk 6 is a circular ring structure, the rotating material distributing disk 4 is arranged in the fixed material distributing disk 6, the fixed material distributing disk 6 coincides with the center of the rotating material distributing disk 4, the fixed material distributing disk 6 is provided with two through holes penetrating the inner and outer walls, the two through holes coincide with the axis of the material distributing channel 9, the rotating material distributing disk 4 is provided with a cache slot, and the output end of the stepper motor 8 is fixedly connected to the center of the rotating material distributing disk 4.

[0028] Further, the mounting mechanism includes a base 14, a mounting column 13 and an outer shell 11, the mounting column 13 is fixed on the base 14, the outer shell 11 is mounted on the mounting column 13, the storage bin 2 is fixed in the outer shell 11, the fixed material distribution plate 6 is fixedly mounted at the bottom of the outer shell 11, and the bottom of the outer shell 11 is provided with a discharge channel 12 that is axially overlapped with the material distribution channel 9. The bottom of the stepper motor 8 is mounted on the mounting column 13, and the outer shell 11 is provided with a notch for the stepper motor 8 to be installed. The output end of the stepper motor 8 is fixedly connected to one end of the rotating shaft 5, and the other end of the rotating shaft 5 is fixedly connected to the center of the rotating material distribution plate 4.

[0029] It can be understood that the buffer groove is formed by extending the radial outer wall of the rotating material distribution plate 4 toward the center, and the inner diameters of the material distribution channel 9, the through hole, the buffer groove and the discharge channel 12 are the same.

[0030] In the above technical solution, when the power is first plugged in, the device will initialize the rotating material distribution disc 4, so that it automatically rotates to a preset initial numerical position to ensure that the material distribution disc is in a standard starting state. Thereafter, each time the device is started, the material distribution disc 4 will rotate at an angle of 180°. In the process of the magnet entering the through hole of the fixed material distribution disc 6 and waiting for material to be taken, the stepper motor 8 is started by the start switch 7, and the rotating material distribution disc 4 is driven by the rotating shaft 5 to rotate. When the buffer slot coincides with the material distribution channel 9, the magnet enters the buffer slot; the rotating material distribution disc 4 continues to rotate, and when the buffer slot containing the magnet coincides with the discharge channel 12, the magnet is taken through the discharge channel 12.

[0031] It should be noted that the slot of the buffer slot is provided with an arc-shaped notch 10. The arrangement of the arc-shaped notch enables the device to take magnetic particles of different size ranges.

[0032] Furthermore, a top cover 1 is provided on the top of the storage bin 2 .

[0033] It can be understood that the base 14 is provided with a start switch 7 for controlling the power supply of the stepping motor 8 and the electromagnetic coil 3 .

[0034] The working principle of this embodiment is as follows:

[0035] How it works

[0036] The magnetic particle automatic material taking device of the present invention realizes the function of taking out the magnetic particles in the storage bin and distributing them into the experimental container through an automated process. The specific working principle is as follows:

[0037] The magnets are first stored in the storage bin 2, the bottom of which is funnel-shaped, which is conducive to the flow of the magnets. A material distribution port is provided at the center of the bottom of the storage bin, and the material distribution port extends downward to form a material distribution channel 9. The material distribution channel 9 is made of metal material, and an electromagnetic coil 3 is sleeved on the outer wall.

[0038] When the device is powered on, the electromagnetic coil 3 is powered on and generates a magnetic field, which attracts the magnetic particles in the storage bin, and the magnetic particles enter the material distribution channel 9 through the material distribution port and wait for further distribution. This process ensures that the magnetic particles can smoothly enter the material distribution system.

[0039] When the magnet enters the through hole of the fixed distribution disc 6 through the distribution channel 9, the user starts the stepper motor 8 by starting the switch 7. The output end of the stepper motor 8 is connected to the rotating distribution disc 4 through the rotating shaft 5, driving the rotating distribution disc 4 to rotate.

[0040] During the rotation of the rotating material distribution disc 4, when the buffer groove overlaps with the material distribution channel 9, the magnetic particles enter the buffer groove from the material distribution channel 9 for temporary storage. The magnetic particles in the buffer groove continue to rotate with the rotating material distribution disc 4.

[0041] When the rotating material distribution disc 4 continues to rotate and the buffer slot coincides with the discharge channel 12, the magnetic particles stored in the buffer slot are taken out through the discharge channel 12 and enter the experimental container. Through the precise control of the rotating material distribution disc 4, the distribution and retrieval process of the magnetic particles can be performed very accurately.

[0042] When the device is powered on for the first time, the rotating material distribution disc 4 will be initialized and automatically rotated to a preset initial position to ensure that the device works in a standard starting state. After that, each time the device is started, the rotating material distribution disc 4 will rotate 180° to ensure accurate distribution and discharge of the magnets.

[0043] In order to prevent external drug particles or impurities from entering the storage bin 2 and contaminating the magnets, a top cover 1 is provided on the top of the storage bin 2. The top cover 1 can effectively isolate external particles, ensure the cleanliness of the magnets in the storage bin and the accuracy of the material distribution process.

[0044] In order to cope with magnetic particles of different size ranges, an arc-shaped notch 10 is provided at the notch of the cache slot. The design of the arc-shaped notch can better adapt to magnetic particles of different sizes, ensuring that the magnetic particles smoothly enter the discharge channel 12 to avoid jamming or retention.

[0045] In summary, through the electromagnetic coil attracting the magnets, the stepper motor controlling the rotation of the rotating distribution plate, and the precise channel design, the present invention realizes the automatic material collection and precise distribution of the magnets, greatly improves the work efficiency, and at the same time avoids the risk of drug particles in the glove box contaminating the magnets, ensuring the cleanliness and accuracy of the experimental process.

[0046] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments including components are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
