Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of automated reagent filling equipment, and more specifically, it relates to an automatic filling machine for reagent filling. Background Technology
[0002] In the fields of medical testing, biopharmaceuticals, and chemicals, reagent filling demands extremely stringent requirements for precision, hygiene, safety, and corrosion resistance. Traditional filling equipment generally suffers from the following technical deficiencies:
[0003] 1. Insufficient structural stability: The base frame is mostly assembled with bolts or has a single-layer support structure. It is easily affected by vibration during equipment operation, which can cause the filling unit to shift and affect the positioning accuracy.
[0004] 2. Misalignment in transmission positioning: The indexing turntable has a simple limiting groove design (such as a rectangular groove), making it easy for reagent bottles to tip over when switching workstations. In addition, the feed conveyor belt is not coaxially connected to the turntable, causing the reagent bottle to shift or get stuck, resulting in a low yield rate.
[0005] III. Filling accuracy and corrosion prevention defects: The injection tube is mostly made of metal. Corrosive reagents can corrode the tube and cause contamination. In addition, the flow control of the metering valve fluctuates greatly, and the injection tube is too high from the reagent bottle mouth, which causes splashing and bubbles.
[0006] IV. Poor sealing reliability: Traditional suction cups have insufficient adsorption force, resulting in a high rate of cap detachment during reagent transfer. Furthermore, the excessive height difference between the feed port and the cap removal plane further exacerbates cap tilting.
[0007] Therefore, this utility model provides an automatic filling machine for reagent filling. Utility Model Content

[0041] This utility model provides an automatic filling machine for reagent filling. Please refer to [link / reference]. Figures 1 to 6As shown, it includes:
[0042] The base frame 1 is formed by welding a bottom support cabinet 11 and a frame skeleton 12, and the frame skeleton 12 has a layered truss structure.
[0043] Indexing transmission system 2, which is integrated into the base frame 1, includes a feeding conveyor belt 21 and a coaxially connected circular turntable 22, with an equal-angle arc-shaped limiting groove 221 on the edge of the circular turntable 22.
[0044] The filling unit 3 is fixed on the frame skeleton 12. The filling unit 3 includes a storage hopper 31 and a connected multi-channel filling head 32. The end of the multi-channel filling head 32 is fitted with a pneumatic metering valve 33. The injection tube 34 extends below the valve body of the pneumatic metering valve 33.
[0045] The sealing unit 4 is installed directly above the circular turntable 22. The sealing unit 4 includes a vibrating feeding device 41 and a sealing execution device 42. The rotation axis of the sealing execution device 42 coincides with the central axis of the arc-shaped limiting groove 221 of the circular turntable 22.
[0046] The pneumatic-electric integrated system 5 includes a pneumatic power unit and a PLC controller. The pneumatic power unit is connected to the pneumatic metering valve 33 through a pressure-resistant hose 51, and the PLC controller is installed in the bottom support cabinet 11.
[0047] It should be noted that the following design is adopted in this application: the base frame 1 provides high rigidity support through the welded structure of the bottom support cabinet 11 and the layered truss skeleton 12, which has strong vibration resistance and ensures long-term stable operation of the equipment; the indexing and transmission system 2 integrates the feeding conveyor belt 21 and the circular turntable 22 to realize continuous material input and intermittent precise positioning, thereby improving transmission efficiency; the filling unit 3 and the capping unit 4 are respectively fixed on the truss skeleton 12 and directly above the turntable, with a compact layout that reduces space occupation.
[0048] The multi-channel filling head 32, combined with the pneumatic metering valve 33, controls the reagent flow rate. The injection tube 34 extends to the mouth of the reagent bottle to avoid liquid splashing and ensure filling accuracy. The rotating shaft of the capping actuator 42 coincides with the central axis of the arc-shaped limiting groove 221 to ensure that the reagent cap and the reagent are accurately aligned.
[0049] The pneumatic-electric integrated system 5 coordinates the entire process of indexing, filling, and capping through a PLC controller, enabling unmanned operation. Furthermore, the pneumatic power unit drives the pneumatic metering valve 33, which has a fast response speed, high repeatability, and is suitable for corrosive reagent environments.
[0050] The base frame 1 also includes vertical columns 13. The frame skeleton 12 includes a first horizontal truss 121 and a second horizontal truss 122. The first horizontal truss 121 suspends the filling unit 3, and the second horizontal truss 122 suspends the capping unit 4. The drive motor of the circular turntable 22 is placed inside the bottom support cabinet 11 to reduce vibration interference, lower noise, and extend equipment life. The first horizontal truss 121 and the second horizontal truss 122 are both bolted to the bottom support cabinet 11 through the vertical columns 13. This application uses the first horizontal truss 121 to suspend the filling unit 3 and the second horizontal truss 122 to suspend the capping unit 4. The bolted connection of the vertical columns 13 ensures that each unit is independently adjustable, facilitating maintenance and upgrades.
[0051] The capping execution device 42 is fixed to the second horizontal truss 122 via a connecting column 123. A lifting cylinder 124 is provided on the connecting column 123. The movable end of the lifting cylinder 124 is connected to the capping execution device 42. A vacuum suction cup 421 is provided at the end of the capping execution device 42. The lifting cylinder 124 controls the lifting stroke of the capping execution device 42, and works with the vacuum suction cup 421 to adsorb reagent caps, resulting in smooth operation. The height difference between the cap-removing plane of the vacuum suction cup 421 and the feeding port of the vibrating feeding device 41 is less than or equal to 5mm, shortening the cap-removing path and preventing reagent caps from shifting or falling off.
[0052] The vibrating feeding device 41 includes a feeding pan 411, a vibrator 412, a rotating motor 413, a rotating disc 414, a guide rail 415, and a feeder 416. The rotating motor 413 is located at the bottom center of the feeding pan 411, and its output is connected to the feeding pan 411. The vibrator 412 is also located at the bottom of the feeding pan 411. The discharge port of the feeding pan 411 is connected to the inlet of the guide rail 415. The outlet of the guide rail 415 is located on the circular turntable 22. The feeder 416 is provided at the outlet of the guide rail 415. The feeder 416 is provided with a discharge guide plate 417. The discharge guide plate 417 accurately guides the reagent cap to the bottom of the capping execution device 42 for easy capping. The vibrator 412 and the transfer motor 413 work together to drive the feed tray 411. The reagent caps are oriented and arranged by the guide rail 415 and the discharge guide plate 417, resulting in a high feeding success rate.
[0053] The rubber contact surface of the vacuum suction cup 421 is provided with annular raised texture, the texture depth of which is 0.5mm. The outer diameter of the vacuum suction cup 421 matches the diameter of the standard reagent cap. The annular raised texture (0.5mm deep) on the rubber contact surface increases the friction force, matches the outer diameter of the standard reagent cap, and improves the adsorption force by 30%, preventing the reagent cap from slipping off.
[0054] The inner wall of the injection tube 34 is coated with a polytetrafluoroethylene (PTFE) anti-corrosion layer. The outer diameter of the injection tube 34 is Φ3±0.1mm. The length of the injection tube 34 extends to a position 10mm from the reagent bottle opening. The PTFE coating on the inner wall of the injection tube 34 is resistant to strong corrosive reagents (such as acids and alkalis). The outer diameter tolerance of ±0.1mm ensures stable liquid flow. Extending to 10mm from the reagent bottle opening reduces the generation of air bubbles.
[0055] The pneumatic power unit includes a pneumatic input pipe 52, which is connected to the pressure-resistant hose 51. A pneumatic valve 521 is installed at one end of the pneumatic input pipe 52, and the pneumatic input pipe 52 is connected to a pneumatic pressure source through the pneumatic valve 521. A pressure relief device 522 is installed at the other end of the pneumatic input pipe 52. The pressure relief device 522 automatically releases overload pressure, and the pneumatic valve 521 precisely adjusts the pneumatic pressure input to ensure the long-term stable operation of the pneumatic metering valve 33.
[0056] The circular turntable 22 has an arc-shaped limiting groove 221 in which a nylon slider is embedded. The upper surface of the nylon slider has a V-shaped guide surface with an included angle of 90°. This design of the circular turntable 22 reduces friction damage to the reagent bottle body, improves the guide error tolerance, and is suitable for different reagent bottle types.
[0057] The bottom support cabinet 11 is provided with an expansion slot, in which a detachable IO module is embedded. The detachable IO module is connected to the PLC controller via an aviation connector, which supports plug-and-play for peripheral devices such as sensors and actuators, reducing expansion costs.
[0058] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
