[0002] With the rapid development of industrial automation technology, the demand for automatic raw material selection and dispensing in production lines is increasing. In traditional production models, manual material selection has many drawbacks, such as cumbersome operation, low efficiency, and susceptibility to errors. Although existing automated material selection devices can achieve partial automation, they still have limitations in accuracy and flexibility, failing to fully meet the demands of high-precision and high-efficiency production. Therefore, there is an urgent need for a new, efficient, flexible, and precise raw material selection and dispensing device. Summary of the Invention

[0012] Secondly, a control method for a database-based valve-operated material selection device as described in any of the first aspects is provided, including:

[0013] Step 1: Receive raw material selection instructions and query the database to obtain the standard graduation angle;

[0014] Step 2: Calculate the target rotation angle based on the standard graduation angle and compensation coefficient;

[0015] Step 3: Drive the servo motor to rotate the nylon disk 39 according to the target rotation angle; the injection component injects material.

[0016] Step 4: Obtain the actual rotation angle through the angle sensor, and determine whether the deviation between the actual rotation angle and the target rotation angle is greater than the angle deviation threshold. If yes, stop the machine immediately and record the accident; otherwise, proceed to step 5.

[0026] 4.

After 1000 consecutive runs, the angle deviation of the system remains at ±0.1°, and the stability is improved by 76%.

[0027] 5.

[0036] The present invention will be further described below with reference to embodiments. The description of the embodiments below is only for the purpose of helping to understand the present invention. It should be noted that those skilled in the art can make several modifications to the present invention without departing from the principle of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.

[0037] Example 1:

[0038] To address the problems of the prior art, Embodiment 1 of this application provides a database-based valve-operated material selection device, comprising:

[0039] The device comprises a drive system 1, a housing component 2, a rotating component 3, a docking component 4, a material injection component 5, and a database management system.

The drive system 1 includes a servo motor 11 and a reducer 12, which are used to receive the target rotation angle signals generated by the database management system and drive the rotating component 3 to rotate. The housing component 2 includes a frame 21 and an indexing plate 22. The indexing plate 22 is mounted on the frame 21 and has 160 sets of mounting holes evenly distributed on it for fixing the valve seat slider 51. Each set of holes corresponds to the positioning coordinates of the injection component for a certain raw material. The rotating component 3 includes a rotating shaft 32 and a nylon disc 39. The rotating shaft 32 is connected to the servo motor 11 through the reducer 12, and the nylon disc 39 is connected to the rotating shaft 32. The docking component 4 is used to dock the rotating component 3 and the injection component 5.

[0041] The database architecture is a layered structure, such as... Figure 1 As shown, the database architecture includes a basic layer: raw material static data and equipment parameter library; an operation layer: a scale angle matrix and a material injection pressure parameter table; and an optimization layer: a historical operation record library, an environmental compensation library, and an equipment wear model.

[0042] The rotating component 3 also includes a rotating frame 31, a rotating bushing 33, a rotating transition plate 34, a reducer gear 35, a magnetic cylinder plate 36, a stroke connecting plate 37, and a nylon disc fixing plate 38; wherein, the rotating frame 31 is connected to the frame 21 of the housing component 2 at the top for fixing the rotating component 3; the rotating bushing 33 and the rotating transition plate 34 are installed below the rotating shaft 32, the rotating bushing 33 is used to protect the rotating shaft 32, and the rotating transition plate 34 is used to control the nylon disc 39 to rotate to the corresponding angle; the reducer gear 35 and the magnetic cylinder plate 36 are also included. The reducer 12 is connected and a rotating shaft 32 is installed; the rotating transition plate 34 is used to connect the rotating shaft 32 and the magnetic cylinder plate 36, and the magnetic cylinder plate 36 is installed below the rotating transition plate 34; the stroke connecting plate 37 is used to connect the magnetic cylinder plate 36 and the nylon disc fixing plate 38, and the nylon disc 39 is installed on the nylon disc fixing plate 38, and is used to drive the servo motor 11 to rotate precisely to the target angle, so that its center hole is precisely aligned with the specified raw material position on the indexing plate 22, so as to achieve selective feeding of 160 kinds of raw materials.

[0043] The rotating component 3 can reduce the output speed of the servo motor 11 by adjusting the gear ratio of the reducer 12, while maintaining the output torque. This is used to precisely control the angle of the rotating device. Based on the angle data stored in the database, the nylon disc 39 in the rotating component is controlled to rotate to the specified position, thus completing the selection of the required raw materials and further improving the accuracy and stability of angle control.

[0044] The housing component 2 also includes a main board 23 on the frame and a large middle frame plate 24; the main board 23 on the frame is connected to the frame 21 and is used to fix the rotating frame 31 of the rotating component 3; the large middle frame plate 24 is used to mount the indexing plate 22 on the frame 21.

[0045] Example 2:

[0046] Based on Embodiment 1, Embodiment 2 of this application provides a more specific database-based valve-driven material selection device, including:

[0047] Drive system 1, housing components 2, rotating components 3, docking components 4, material injection components 5, and database management system;

[0048] The database management system stores raw material data for generating target rotation angle signals. The raw material data stored in the database includes: raw material ID, temperature compensation coefficient, humidity compensation coefficient, historical best indexing angle, and equipment wear correction parameters. Specifically, the rotating component can reduce the output speed of the servo motor by adjusting the gear ratio of the reducer while maintaining torque output. This allows for precise control of the rotating device's angle. Based on the angle data stored in the database, the nylon disc in the rotating component is controlled to rotate to a designated position, completing the selection of the required raw material and further improving the accuracy and stability of angle control.

[0049] The drive system 1 includes a servo motor 11 and a reducer 12, which are used to receive the target rotation angle signal generated by the database management system and drive the rotating component 3 to rotate; the housing component 2 includes a frame 21 and an indexing plate 22, with the indexing plate 22 mounted on the frame 21; the rotating component 3 includes a rotating shaft 32 and a nylon disc 39, with the rotating shaft 32 connected to the servo motor 11 via the reducer 12 and the nylon disc 39 connected to the rotating shaft 32; the docking component 4 is used to dock the rotating component 3 and the injection component 5.

[0050] The docking component 4 includes a cylinder 41, a pull rod 42, a pull rod support 43, a pull rod pin 44, a pull rod bearing 45, a support bearing 46, and a support pin 47. The cylinder 41 is connected to a magnetic cylinder plate 36, and the end of the cylinder 41 is connected to the pull rod 42 and the pull rod support 43. The pull rod 42 is equipped with the pull rod bearing 45 and the pull rod pin 44, and the pull rod support 43 is equipped with the support bearing 46 and the support pin 47. The two bearings ensure precise docking between the docking component 4 and the injection component 5. Simultaneously, the bearings play a crucial role during the extension and retraction of the cylinder 41, effectively reducing friction between the docking component 4 and the front end of the injection component 5, thereby ensuring smooth docking operation, reducing wear, and extending the service life of the equipment.

[0051] The injection component 5 includes a valve seat slider 51, a valve seat track 52, a valve body fixing seat 53, a valve body 54, a spray hole 55, a wiping device 56, a piping system 57, and a flow meter 58. The valve seat slider 51 is fixed on the indexing plate 22 and slidably connected to the valve seat track 52. One end of the valve seat track 52 is connected to the valve body fixing seat 53 to enable the sliding of the valve body 54. The upper end of the valve body 54 is connected to the valve body fixing seat 53, and the lower end of the valve body 54 is connected to the spray hole 55 for injecting raw materials. The wiping device 56 is installed on the indexing plate 22 and is used to wipe the spray hole 55 after injection. The wiping device 56 includes a steel ball, a steel ball seat, and a steel ball seat connecting rod. One end of the steel ball seat connecting rod is connected to the indexing plate 22 of the housing component 2, and the other end is fitted with the steel ball seat. The steel ball is installed on the steel ball seat and is used to wipe the spray hole 55 after injection to ensure that the spray hole 55 is clean. In addition, the piping system 57, flow meter 58 and valve body 54 are connected to precisely control the amount of injected raw material.

[0052] Furthermore, the valve-operated material selection device includes a safety device that monitors the pressure of the pipeline system 57 in real time via a pressure sensor. When the pressure is ≥10.5MPa or other abnormal conditions occur, its control unit will activate emergency protection: close the emergency stop valve and cut off the raw material supply; cut off the power to the servo motor 11 and lock the rotating part 3; demagnetize the magnetic cylinder plate 36, and return the material injection part 5 to its original position. The current raw material ID, the amount of material injected, and the pressure value are recorded in the database management system for fault traceability. Therefore, this application can prevent failures caused by excessive pressure or other abnormal conditions, and is also equipped with a filter to ensure the purity of the raw materials and the stable operation of the system. This invention adopts an integrated design of safety device and filter, overcoming the failure risks caused by pressure overload or raw material contamination in traditional equipment through a pressure threshold-triggered emergency stop mechanism (emergency stop at 10.5MPa) and raw material impurity filtration, thereby reducing the system failure rate by 60% and ensuring production safety and raw material purity.

[0053] It should be noted that the parts in this embodiment that are the same as or similar to those in Embodiment 1 can be referred to each other, and will not be repeated in this application.

[0054] Example 3:

[0055] Building upon Example 2, Example 3 of this application provides a control method for a database-based valve-operated material selection device. Before use, all relevant data of the raw materials (such as name, physical properties, injection volume, and selection angle) are stored in a database system. During production, the control system automatically queries the database to retrieve the corresponding raw material information based on actual needs. Specifically, for example... Figure 2 As shown, the method includes:

[0056] Step 1: Receive the raw material selection instruction and query the database to obtain the standard graduation angle.

[0057] For example, the raw material selection command allows the user to input the ID of the required raw material and the target dosage according to the formula. Then, the database can be queried based on the raw material ID to retrieve the corresponding static parameters, such as the standard graduation angle.

[0058] Step 2: Calculate the target rotation angle based on the standard graduation angle and compensation coefficient.

[0059] Specifically, the system collects the current ambient temperature and humidity using sensors, retrieves a pre-stored compensation coefficient table and historical operation records, obtains the temperature compensation coefficient, humidity compensation coefficient, and current wear coefficient, and outputs the target angle according to the calculation formula for generating the composite target angle. The calculation formula for the target rotation angle is as follows:

[0060]

[0061] in, Rotate by the target angle. For standard graduation angles, This is the temperature compensation coefficient (unit: 1 / ℃), which, through experimental calibration, has a typical value of 0.002 / ℃. Temperature deviation (the difference between the current temperature and the standard temperature of 20°C, in °C). This is the humidity compensation factor (unit: 1 / %RH), calibrated experimentally, with a typical value of 0.001 / %RH. Humidity deviation (the difference between the current humidity and the standard humidity of 50%RH, in %RH). The wear coefficient of the equipment. This is the cumulative wear value, quantified based on parameters such as gear clearance and bearing wear.

[0062] Step 3: Drive the servo motor 11 to rotate the nylon disc 39 according to the target rotation angle; the injection component 5 injects material.

[0063] Specifically, the target rotation angle is converted into a pulse signal. The servo motor 11 reduces its speed and amplifies its torque through the reducer 12, ensuring precise transmission of the rotating shaft 32. The database management system retrieves the pre-stored reducer gear ratio parameter i and calculates the number of output pulses from the servo motor 11 according to the formula:

[0064]

[0065] in, The encoder resolution is set to servo motor 11. Servo motor 11 drives reducer 12 based on the number of pulses, which reduces the output speed to 1 / i times and amplifies the torque to i times via reducer gear 35, ensuring that rotating shaft 32 precisely controls the rotation angle of nylon disc 39 with low speed and high torque. When nylon disc 39 rotates to the designated position, material selection is complete.

[0066] This invention employs a gear ratio parameterized control and closed-loop calibration mechanism. By dynamically adjusting the rotation speed and torque of the rotating shaft 32 through the pulse count of the servo motor 11, it overcomes the problem of cumulative deviation caused by gear wear in traditional open-loop control. This reduces the angle error rate after long-term operation from ≥1.5% to ≤0.2%, shortens the single positioning time to 0.5 seconds (1.2 seconds for traditional devices), and improves efficiency by 30%.

[0067] After the rotating component 3 rotates to the designated position, the tie rod bearing 45 and the support bearing 46 mate with the valve body fixing seat 53, completing the docking of the docking component 4 and the injection component 5. After docking, the cylinder 41 retracts, and the valve body 54 and the nozzle 55 slide to the center position of the nylon disc 39 under the sliding of the valve seat track 52, thereby ensuring that the nozzle is aligned each time material is added and that the raw material is accurately injected into the required position. The valve-driven material selection method, by controlling the rotation angle of the nylon disc 39, ensures that the device can accurately control the position of the nozzle 55 when selecting different raw materials, avoiding material mixing and improving the feeding accuracy and equipment efficiency. In addition, the pipeline system 57 and the flow meter 58 monitor and adjust the injection volume of the nozzle 55 in real time. The flow meter 58 provides real-time feedback on the injection volume, and the error data is sent back to the database to update and optimize the model (refer to subsequent step 5).

[0068] Furthermore, in step 3, the injection component 5 employs a staged injection method during the raw material injection process, with the injection volume decreasing progressively with each injection. This ensures that the amount of liquid injected each time becomes smaller and smaller, effectively reducing the error in each injection and optimizing the injection accuracy. The formula for the staged injection method is:

[0069]

[0070] The attenuation coefficient k = 0.05.

[0071] Step 4: Obtain the actual rotation angle through the angle sensor, and determine whether the deviation between the actual rotation angle and the target rotation angle is greater than the angle deviation threshold. If yes, stop the machine immediately and record the accident; otherwise, proceed to step 5.

[0072] For example, a high-precision angle sensor is installed at the end of the rotating shaft 32 to monitor the actual angle and calculate whether the angle deviation is greater than 0.1°. If so, the machine is stopped immediately and the accident is recorded. If not, the next step is performed.

[0073] Step 5: Obtain the actual injection volume through flow meter 58, and determine whether the deviation between the actual injection volume and the preset target injection volume is greater than the injection volume deviation threshold. If so, shut down the machine immediately and record the accident; otherwise, update the compensation coefficient.

[0074] For example, flow meter 58 monitors the injection volume in real time, calculates the flow meter error, and determines whether the error is greater than 0.5%. If so, it shuts down the machine immediately and records the incident. If not, it analyzes historical operating data based on the random forest algorithm and updates the compensation coefficient and wear coefficient to optimize the next operation.

[0075] Furthermore, after filling, cylinder 41 extends, the filling component returns to its initial position, valve seat track 52 returns to its original state, and wiping device 56 cleans nozzle 55, thus ending the filling of raw materials. Afterwards, preparations are made for the next round of raw material selection and filling. The entire process is controlled by a servo motor and precision reducer, combined with data from the database. This invention enables automated and precise raw material filling. The control method not only reduces manual operation and improves production efficiency but also allows for real-time adjustment of the raw material dosage during filling, avoiding common error problems in traditional batching methods. Through the implementation of this invention, problems such as inaccurate filling and complex equipment in existing technologies can be effectively solved, offering the following advantages: achieving precise filling and automated control of raw materials, reducing the complexity of manual operation; improving the overall efficiency of the production line and shortening the production cycle; ensuring the accuracy and consistency of each filling, avoiding production quality problems caused by inaccurate filling; and providing a flexible control method, using a database for raw material selection and filling to adapt to diverse production needs.

[0076] To verify the effectiveness of the technical solution of this invention, this device was compared with an existing device (XYZ-2000 material selection device). The test environment was: temperature 25±5℃, humidity 50±10%, and the test material was a chemical liquid with a viscosity range of 10-1000 mPa·s. The accuracy of the graduation angle, the injection error rate, and the equipment life were tested at different temperatures.

[0077] The graduation angle deviation of the present invention and the XYZ-2000 device was tested at different temperatures (20℃, 30℃, and 40℃). Each group was repeated 10 times, and the average value was taken. The experimental results are shown in Table 1. It can be seen that the angle deviation can be controlled within ±0.12° by using a dynamic compensation algorithm (temperature compensation coefficient α=0.002 / ℃), while the deviation of the existing technology increases significantly with increasing temperature due to the lack of a compensation mechanism.

[0078] Table 1 Comparison of graduation angle accuracy at different temperatures

[0079]

[0080] Taking a target injection volume of 100 mL as an example, 50 consecutive injections were performed, and the error rate (the percentage deviation between the actual injection volume and the target value) was statistically analyzed. The experimental results are shown in Table 2. The present invention uses a step-by-step decreasing injection algorithm (attenuation coefficient k=0.05), which effectively suppresses overshoot caused by inertia, reducing the error rate to 0.45% and the standard deviation to a smaller value, indicating better stability.

[0081] Table 2 Comparison of Injection Error Rates of Different Equipment

[0082]

[0083] After 1000 consecutive cycles, the wear of key components (connector bearing, nylon disc) was measured. The experimental results are shown in Table 3. This invention adopts a magnetic cylinder plate and dual bearing linkage design, which reduces frictional resistance by 70%, increases the docking success rate to 99.8%, and reduces the wear of key components to only 1 / 4 of that in the prior art, significantly extending the equipment life.
