Description

Technical Field

[0002] A magnetic stir bar is a laboratory instrument accessory that uses the magnetic field generated by the base of a magnetic stirrer to drive the rotation of the magnetic bar, thereby realizing the mixing of liquids. Magnetic stir bars are commonly used for the stirring and mixing of solutions, and are mostly used in laboratories such as chemistry and biology. During the experiment process, magnetic stir bars need to be frequently used. Between multiple experiments or different experimental steps, the transfer and positioning of magnetic stir bars usually require manual operation. Manual operation is prone to introducing human errors, which affects the accuracy of transfer and positioning, and further reduces the accuracy and reliability of subsequent experiments. Moreover, when performing manual operation, a large amount of time is required, resulting in low work efficiency in the entire laboratory, increasing the time and cost of manual operation. At the same time, during manual operation, the magnetic stir bar is directly exposed, and there is also a possibility of polluting the environment during the transfer process.

Detailed implementation manners

[0017] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with the detailed implementation manners.

[0018] As Figures 1-4 shown, an experimental magnetic stir bar transfer device includes a base 1, a clamping mechanism 2 and a recovery structure 3. The clamping mechanism 2 is installed on an externally connected moving structure, and the recovery structure 3 is arranged on the base 1. The clamping mechanism 2 includes a protective housing 4, a drive device 5, a telescopic rod 6, a connecting rod 7, a clamping piece 8 and a disengaging sleeve 9. An installation seat is provided on the protective housing 4, the drive device 5 is fixed on the installation seat, the telescopic rod 6 is fixedly connected with the connecting rod 7, and the telescopic rod 6 is connected with the drive device 5. The clamping piece 8 is arranged at the lower end of the connecting rod 7, and the disengaging sleeve 9 is sleeved on the connecting rod 7. Compared with the traditional manual operation mode, this device can realize the automatic transfer and positioning of magnetic stir bars, greatly improving the efficiency of laboratory work, reducing the time and cost of manual operation, and since it adopts automatic operation, reducing the possibility of human error and improving the accuracy and reliability of experiments.

[0019] When transferring the magnetic stir bar, the entire clamping mechanism 2 moves to the position where the magnetic stir bar to be transferred is located. The drive device 5 drives the movement of structures such as the telescopic rod 6 and the connecting rod 7, so as to use the clamping piece 8 to clamp the magnetic stir bar. Subsequently, the clamping mechanism 2 moves to the recovery structure 3. The connecting rod 7, the clamping piece 8 and the magnetic stir bar enter the recovery structure 3. After starting the drive device 5 again, the structures such as the telescopic rod 6 and the connecting rod 7 move upward, and the magnetic stir bar is detached through the disengaging sleeve 9 to realize the recovery of the magnetic stir bar, facilitating the transfer and positioning of the magnetic stir bar.

[0020] Through the above implementation solutions, the recycling structure 3 includes a recycling bin 10, a bin door 13, a column 18, a fixing plate 19 and a reset recycling component 20. The recycling bin 10 is fixed on the base 1. The bin door 13 is arranged inside the recycling bin 10. The fixing plate 19 is fixed on the base 1 through the column 18. The reset recycling component 20 is installed on the fixing plate 19. The recycling structure 3 further includes an opening 11, a rotating sleeve 12, a driven bevel gear 14, a micro motor 15, a driving bevel gear 16 and a sensing device 17. The opening 11 is arranged on the recycling bin 10. The rotating sleeve 12 is connected to the bin door 13 and is rotatably installed at the lower end of the recycling bin 10. The driven bevel gear 14 is fixed on the rotating sleeve 12. The micro motor 15 is connected to the driving bevel gear 16 and is installed inside the base 1. The driving bevel gear 16 is meshed with the driven bevel gear 14. The sensing device 17 is installed inside the base 1. By providing the independent recycling bin 10, the complete sealing of harmful substances during the recycling process is ensured, preventing spillage and cross-contamination, which is beneficial to the protection of the laboratory environment and the health and safety of the staff.

[0021] The reset recycling component 20 includes a fixed seat 2001, a recycling bracket 2002, a V-shaped opening 2003, a guiding rod 2004, a reset spring 2005 and a baffle 2006. The fixed seat 2001 is fixed on the lower surface of the fixing plate 19. The V-shaped opening 2003 is formed on the recycling bracket 2002, and the recycling bracket 2002 is fixedly connected to the guiding rod 2004. The guiding rod 2004 penetrates through the fixed seat 2001. One end of the reset spring 2005 is connected to the fixed seat 2001, and the other end is connected to the recycling bracket 2002. The baffle 2006 is fixed at the end of the guiding rod 2004. By arranging the reset recycling component 20 in the recycling structure 3, the reset spring 2005 can drive the recycling bracket 2002 to reset and cover the upper end of the recycling bin 10, improving the sealing effect. At the same time, the reset spring 2005 does not affect the quick movement and yielding of the recycling bracket 2002, making the operation highly convenient.

[0022] After the clamping mechanism 2 clamps the magnetic stir bar, it moves towards the recovery structure 3. At this time, the hatch 13 in the recovery bin 10 is in an open state. When the clamping mechanism 2 moves, after the telescopic rod 6 moves into the V-shaped opening 2003 on the recovery bracket 2002 in the reset recovery assembly 20, the telescopic rod 6 exerts a force on the recovery bracket 2002. The recovery bracket 2002 moves towards the fixed seat 2001 through the guide rod 2004, and at the same time compresses the reset spring 2005. As the movement progresses, when the connecting rod 7, the clamping member 8, and the magnetic stir bar enter the interior of the recovery bin 10, they stop moving. Subsequently, the micro motor 15 inside the base 1 is started. The micro motor 15 drives the driven bevel gear 14 to rotate through the driving bevel gear 16, so as to drive the hatch 13 to rotate through the rotating sleeve 12 until the hatch 13 closes the opening 11. During this process, the sensing device 17 performs real-time sensing, which can ensure the closing accuracy of the hatch 13. After the hatch 13 is closed, the clamping mechanism 2 is started to drop the magnetic stir bar, realizing the recovery of the magnetic stir bar. At the same time, most of the recovery bracket 2002 covers the recovery bin 10, which can play a role in closing. When the recovery of the magnetic stir bar needs to be carried out again, the micro motor 15 is started again to drive the hatch 13 to open through the relevant structure, then the clamping mechanism 2 is moved outwards to clamp the magnetic stir bar, and then it can be transferred and positioned for recovery according to the above process.
