Description

Technical Field

[0001] This invention relates to an automated liquid level constant distance device, belonging to the field of distance constant distance equipment. Background Technology

[0002] The microparticle preparation device is constructed by combining a high-voltage pulse-modulated electric field as a physical control method with a linkage injection device, becoming an integrated equipment for preparing microparticles. It is mainly used for the batch preparation of core material aqueous solutions and corresponding cell or drug nanoscale gel particles.

[0003] To produce even finer microparticles, most microparticle preparation systems incorporate a high-voltage pulsed electric field between the container and the syringe. This allows the core material inside the syringe to drip from the syringe under the influence of the electric field, forming even finer microparticles. To ensure stable production of fine microparticles, the distance between the reaction liquid surface in the container and the syringe needle must be kept within 30mm. However, as the microparticles drip into the container, the reaction liquid surface rises, reducing the distance between the reaction liquid surface and the syringe needle, thus affecting the microparticle preparation effect. Furthermore, visual observation alone can lead to significant errors.

[0004] For example, the specification of the Chinese invention patent (application number: CN200710158289.X) discloses "a multi-channel electrode with the same changing electric field force". It states that microcapsules can be prepared using a multi-channel electrode, but the distance between the reaction liquid surface and the syringe needle is observed with the naked eye, which has a large error.

[0005] Therefore, we made improvements and proposed an automated liquid level constant distance device. Summary of the Invention

[0006] (i) The technical problem to be solved by the present invention is that when the microparticles fall into the container, the liquid level of the reaction liquid in the container will rise with the drop of the microparticles, the distance between the liquid level of the reaction liquid and the syringe needle will be reduced, which will affect the preparation effect of the microparticles, and the error of the method of observation by the naked eye is large.

[0007] (II) Technical Solution To achieve the above-mentioned objectives, the present invention provides an automated liquid level distance constant device, comprising a base, a linkage injection device disposed on the rear side of the top of the base, an injector for producing microparticle glue disposed on the linkage injection device, a controller disposed in the middle of the top of the base, a horizontal mechanism for holding microparticle glue disposed on the top of the controller, a drive mechanism and an adjustment mechanism for adjusting the distance disposed on the horizontal mechanism, and a camera mechanism for cooperating with the drive mechanism and the adjustment mechanism mounted on one side of the top of the base. The camera mechanism includes a support frame fixedly installed on one side of the top of the base. An industrial camera for monitoring the distance between the liquid level and the syringe needle is fixedly installed on the support frame. By setting up the camera mechanism, drive mechanism, and adjustment mechanism, the industrial camera can replace the naked eye to monitor the liquid level of the reaction liquid in the water tank in real time. The monitoring accuracy is high and the error is small. When the liquid level of the reaction liquid rises, the position of the water tank can be adjusted by controlling the second motor. Furthermore, by rotating the connecting rod, the connecting rod can drive the movable rod to move and adjust the position of the disc blocking the first arc-shaped groove. When the raw material drips into the water tank, the overflowing water can be discharged through the first arc-shaped groove, thereby ensuring that the liquid level of the reaction liquid can always be kept within a safe range without repeated adjustments and without affecting the preparation effect due to changes in the liquid level.

[0008] The drive mechanism includes two connecting frames respectively located at the top of both sides of the controller. The ends of the connecting frames are connected to lead screws via bearings. A second motor for driving the lead screws to rotate is fixedly installed at the bottom of the connecting frames. By setting up the drive mechanism, the water tank can be raised or lowered, adjusting the distance between the liquid level in the water tank and the syringe needle.

[0009] The horizontal mechanism includes an I-beam frame disposed between two lead screws. The rear side of the I-beam frame is slidably connected to both sides of the linkage injection device. A connecting ball is fixedly connected to the middle of the top of the I-beam frame. A water tank is disposed on the connecting ball. A filter frame for holding microparticles is disposed inside the water tank. The filter frame has multiple fine holes for drainage. Multiple first springs are disposed between the filter frame and the I-beam frame.

[0010] The water tank is equipped with L-shaped frames fixedly installed at both ends of its front and rear sides. A first motor is fixedly installed on the L-shaped frame, and a swing rod is fixedly connected to the output shaft of the first motor. By setting up the L-shaped frame, the first motor, and the swing rod, the height of one corner of the water tank can be adjusted when the swing rod rotates downward. In conjunction with the other swing rods, the level of the water tank can be adjusted. When the swing rod rotates upward, it can push the filter frame out of the water tank, so that when people remove the microparticles inside the filter frame, they will not come into contact with the water tank, reducing the probability of people coming into contact with the residual current in the water tank. The L-shaped frame, the first motor, and the swing rod can be used to adjust the level of the water tank and to lift the filter frame to remove the microparticles, making it highly functional.

[0011] The adjusting mechanism includes two rotating cylinders respectively mounted on the middle of both sides of the water tank via bearings. A connecting rod is fixedly connected to the end of each rotating cylinder, and threaded rings that cooperate with the lead screw are provided at the top and bottom of one side of the connecting rod.

[0012] The first gear is fixedly connected to the end of the rotating drum away from the threaded ring. A second gear meshes with the first gear. A third motor is fixedly connected to the middle of the second gear. The third motor is fixedly installed on one side of the bottom of the water tank.

[0013] The rotating drum has a threaded rod internally connected to it. One end of the threaded rod is fixedly connected to a spring telescopic rod, and one end of the spring telescopic rod is fixedly connected to an elastic stop block. Limit grooves are formed on both sides of the threaded rod, and limit blocks are slidably connected inside the limit grooves. The limit blocks are fixedly installed on one side inside the water tank.

[0014] The water tank has a first arc-shaped groove on both sides of its top. A movable rod is slidably connected inside the first arc-shaped groove. A round block is fixedly connected to one end of the movable rod. A disc and a second spring are inserted and connected to the outside of the movable rod. By setting up the first arc-shaped groove, the movable rod, the round block, the disc, and the second spring, the liquid in the water tank can flow out through the first arc-shaped groove, so that when the raw materials drip into the water tank, the liquid level of the reaction liquid can always be kept within a safe range. The safe range of liquid flow can be adjusted by adjusting the position of the disc.

[0015] The water tank has a U-shaped groove at its bottom. Arc-shaped blocks are inserted into both sides of the U-shaped groove. A sealing plate is fixedly connected between two arc-shaped blocks. A connecting block is fixedly connected to the top of one side of the arc-shaped block. An elastic strip is provided on the connecting block. The two ends of the elastic strip are fixedly connected to one side of the water tank. A water tank is placed at the top of the controller. By setting up the arc-shaped blocks, sealing plates, connecting blocks, and elastic strips, when the connecting rod rotates, it can drive the connecting block to move, causing the arc-shaped blocks and sealing plates to descend and no longer block the U-shaped groove. This allows the liquid in the water tank to drain into the water tank through the U-shaped groove.

[0016] Conductive sheets are fixedly installed on one side of the linkage injection device and on one side of the water tank. Attached Figure Description

[0020] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0021] Example 1: like Figure 1 As shown, this embodiment proposes an automated liquid level distance constant device, including a base 1, a linkage injection device 2 is provided on the rear side of the top of the base 1, an injector 3 for producing microparticle glue is provided on the linkage injection device 2, a controller 4 is provided in the middle of the top of the base 1, a horizontal mechanism 6 for holding microparticle glue is provided on the top of the controller 4, a drive mechanism 7 and an adjustment mechanism 8 for adjusting the distance are provided on the horizontal mechanism 6, and a camera mechanism 5 for cooperating with the drive mechanism 7 and the adjustment mechanism 8 is installed on one side of the top of the base 1. The camera mechanism 5 includes a support frame 501 fixedly installed on one side of the top of the base 1. An industrial camera 502 for monitoring the distance between the liquid level and the needle of the syringe 3 is fixedly installed on the support frame 501. By setting up the camera mechanism 5, the drive mechanism 7 and the adjustment mechanism 8, the industrial camera 502 can replace the naked eye to monitor the liquid level of the reaction liquid in the water tank 601 in real time. The monitoring accuracy is high and the error is small. When the liquid level of the reaction liquid rises, the position of the water tank 601 can be adjusted by controlling the second motor 702. Furthermore, by rotating the connecting rod 802, the connecting rod 802 can drive the movable rod 813 to move the adjustment disc 815 to block the position of the first arc groove 812. When the raw material drips into the water tank 601, the overflowing water can be discharged through the first arc groove 812. Thus, the liquid level of the reaction liquid can always be kept within a safe range without repeated adjustment, and the preparation effect will not be affected by changes in the liquid level.

[0022] Example 2: The solution in Example 1 will be further described below with reference to its specific working method. like Figure 1 As shown, in a preferred embodiment, based on the above method, the drive mechanism 7 further includes two connecting frames 701 respectively disposed at the top of both sides of the controller 4. The ends of the connecting frames 701 are connected to lead screws 703 via bearings. The bottom end of the connecting frames 701 is fixedly installed with a second motor 702 for driving the lead screws 703 to rotate. By setting the drive mechanism 7, the water tank 601 can be driven to rise or fall, and the distance between the liquid level in the water tank 601 and the needle of the syringe 3 can be adjusted.

[0023] like Figure 1 , Figure 2 and Figure 10As shown, in a preferred embodiment, based on the above method, the horizontal mechanism 6 further includes an I-beam frame 602 disposed between two lead screws 703. The rear side of the I-beam frame 602 is slidably connected to both sides of the linkage injection device 2. A connecting ball 603 is fixedly connected to the middle of the top of the I-beam frame 602. A water tank 601 is disposed on the connecting ball 603. A filter frame 604 for holding microparticles is disposed inside the water tank 601. The filter frame 604 has multiple fine holes for drainage. Multiple first springs 605 are disposed between the filter frame 604 and the I-beam frame 602. By setting the filter frame 604, microparticles can be placed inside the filter frame 604. When the swing rod 608 lifts the filter frame 604, the liquid inside the filter frame 604 can be discharged through the fine holes, making it convenient for people to remove the microparticles inside the filter frame 604.

[0024] like Figure 1 , Figure 2 and Figure 10 As shown, in a preferred embodiment, based on the above method, an L-shaped frame 606 is fixedly installed at both ends of the front and rear sides of the water tank 601. A first motor 607 is fixedly installed on the L-shaped frame 606, and a swing rod 608 is fixedly connected to the output shaft of the first motor 607. By setting the L-shaped frame 606, the first motor 607, and the swing rod 608, the swing rod 608 can adjust the height of one corner of the water tank 601 during downward rotation. In conjunction with the other swing rods 608, the level of the water tank 601 can be adjusted. When the swing rod 608 rotates upward, it can push the filter frame 604 out of the water tank 601, so that when people take out the microparticles in the filter frame 604, they will not come into contact with the water tank 601, reducing the probability of people coming into contact with the residual current in the water tank 601. The L-shaped frame 606, the first motor 607, and the swing rod 608 can be used to adjust the level of the water tank 601 and to lift the filter frame 604 to take out the microparticles, which is highly functional.

[0025] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, in a preferred embodiment, based on the above method, the adjusting mechanism 8 further includes two rotating cylinders 801 respectively set in the middle of the two sides of the water tank 601 by bearings. The ends of the rotating cylinders 801 are fixedly connected to the connecting rods 802. The top and bottom ends of one side of the connecting rods 802 are provided with threaded rings 803 that cooperate with the lead screw 703. By providing the threaded rings 803, the lead screw 703 can drive the connecting rods 802 and the water tank 601 to move up and down during rotation.

[0026] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, in a preferred embodiment, based on the above method, a first gear 809 is fixedly connected to the end of the rotating drum 801 away from the threaded ring 803, a second gear 810 meshes with the first gear 809, a third motor 811 is fixedly connected to the middle of the second gear 810, and the third motor 811 is fixedly installed on one side of the bottom end of the water tank 601.

[0027] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, in a preferred embodiment, based on the above method, the rotating drum 801 is further provided with a threaded rod 804 internally threaded. One end of the threaded rod 804 is fixedly connected to a spring telescopic rod 805, and one end of the spring telescopic rod 805 is fixedly connected to an elastic abutment 806. Limiting grooves 807 are provided on both sides of the threaded rod 804, and limiting blocks 808 are slidably connected inside the limiting grooves 807. The limiting blocks 808 are fixedly installed on one side inside the water tank 601. By setting the spring telescopic rod 805 and the elastic abutment 806, when the rotating drum 801 rotates, the elastic abutment 806 can abut against the lead screw 703. Therefore, when the threaded ring 803 separates from the lead screw 703, the static friction between the elastic abutment 806 and the lead screw 703 prevents the water tank 601 from descending.

[0028] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, in a preferred embodiment, based on the above method, a first arc-shaped groove 812 is further provided on both sides of the top of the water tank 601. A movable rod 813 is slidably connected inside the first arc-shaped groove 812. A round block 814 is fixedly connected to one end of the movable rod 813. A disc 815 and a second spring 816 are inserted and connected to the outside of the movable rod 813. By setting the first arc-shaped groove 812, the movable rod 813, the round block 814, the disc 815 and the second spring 816, the liquid in the water tank 601 can flow out through the first arc-shaped groove 812, so that when the raw material drips into the water tank 601, the liquid level of the reaction liquid can always be kept within a safe range. By adjusting the position of the disc 815, the safe range of liquid level outflow can be adjusted.

[0029] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, in a preferred embodiment, based on the above method, a U-shaped groove 817 is further provided at the bottom of the water tank 601. Arc-shaped blocks 818 are inserted and connected to both sides inside the U-shaped groove 817. A sealing plate 819 is fixedly connected between the two arc-shaped blocks 818. A connecting block 820 is fixedly connected to the top of one side of the arc-shaped block 818. An elastic strip 821 is provided on the connecting block 820. The two ends of the elastic strip 821 are fixedly connected to one side of the water tank 601. A water tank 822 is placed at the top of the controller 4. By setting the arc-shaped blocks 818, sealing plate 819, connecting block 820 and elastic strip 821, when the connecting rod 802 rotates, it can drive the connecting block 820 to move, so that the arc-shaped blocks 818 and sealing plate 819 descend and no longer block the U-shaped groove 817. Thus, the liquid in the water tank 601 can be discharged into the water tank 822 through the U-shaped groove 817.

[0030] like Figure 1 As shown, in a preferred embodiment, based on the above method, conductive sheets 9 are further fixedly installed on one side of the linkage injection device 2 and one side of the water tank 601.

[0031] Example 3: The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods. Specifically, during operation / use, this automated liquid level constant distance device works as follows: The third motor 811 drives the second gear 810, the first gear 809, and the rotating drum 801 to rotate, causing the threaded ring 803 to separate from the lead screw 703. The threaded rod 804, restricted by the limiting groove 807 and the limiting block 808, moves with the rotation of the rotating drum 801, causing the elastic abutment 806 to abut against the lead screw 703. The connecting rod 802 contacts the movable rod 813 before the connecting block 820, causing the movable rod 813 to move upwards. Alternatively, it can... The position of the disc 815 is adjusted by manually pulling it. After adjustment, the threaded ring 803 is controlled to contact the lead screw 703. When the raw material enters the reaction liquid in the water tank 601, the liquid level rises and the overflowing liquid flows out through the first arc groove 812 and drips into the water tank 822. The industrial camera 502 can monitor the distance between the syringe needle 3 and the liquid surface in real time, and adjust the water tank 601 by controlling the rotation of the lead screw 703. At the same time, the position of the overflowing water level can be adjusted by adjusting the position of the disc 815. When it is necessary to remove the microparticles, the first motor 607 is controlled to drive the swing rod 608 to rotate, causing the filter frame 604 to rise and extend out of the water tank 601. The liquid in the filter frame 604 is discharged through the fine holes, and the microparticles can be removed from the filter frame 604. When it is necessary to drain the liquid in the water tank 601, repeat the above process, control the connecting rod 802 to contact the connecting block 820, so that the connecting block 820 drives the sealing plate 819 to descend, no longer sealing the U-shaped groove 817, and the liquid can be drained into the water tank 822 through the U-shaped groove 817.

[0032] The above embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Although the invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the invention do not depart from the spirit and scope of the invention and should be covered within the scope of the claims of the invention.
