Description

Technical Field

[0001] This invention belongs to the field of spectacle lens processing technology, specifically relating to a fully automatic lens grooving and chamfering machine control system. Background Technology

[0002] Fully automatic lens grooving and chamfering machines are key equipment in spectacle lens processing, primarily used for grooving and chamfering the edges of lenses to meet the assembly requirements of different frames. However, current market offerings of this type of equipment still suffer from several technical shortcomings in practical applications: First, traditional equipment often combines mechanical transmission with manual adjustment, making processing accuracy susceptible to human factors, resulting in low repeatability and poor processing consistency. Second, their control systems rely heavily on discrete electrical components and relay logic, leading to slow system response, insufficient stability, and difficulty in troubleshooting. Third, the equipment often experiences significant vibration and noise during operation, affecting not only the surface quality of the processed material but also limiting the equipment's lifespan. Furthermore, most machines lack adaptive processing capabilities, failing to automatically adjust processing parameters based on differences in lens material and curvature, resulting in unsatisfactory processing effects and low yield rates. Finally, existing human-machine interfaces are generally rudimentary and complex to operate, hindering rapid adjustment of processing parameters and production management, and failing to meet the flexible demands of the modern eyewear industry for small-batch, multi-variety, and high-precision processing. Summary of the Invention

[0003] The present invention aims to provide a fully automatic lens grooving and chamfering machine control system to solve the comprehensive technical problems in the prior art, such as the large influence of human factors on processing accuracy, slow system response, poor stability, and lack of adaptive processing capability.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A fully automatic lens grooving and chamfering machine control system includes a voltage stabilizing module, a grinding module, a multi-axis motion control module, a human-machine interaction module, a microcontroller, a data transmission module, a cleaning module, and a data acquisition module; the control system is powered by an external power adapter. The microcontroller is electrically connected to the voltage stabilizing module, grinding module, multi-axis motion control module, human-machine interaction module, data transmission module, cleaning module, and data acquisition module, respectively. The control process of the control system is as follows: the user sets the processing parameters through the human-machine interaction module and sends them to the microcontroller; the microcontroller controls the multi-axis motion control module to transport the lens to the data acquisition area; the data acquisition module collects the lens's external dimensions and sends them back to the microcontroller; the microcontroller calculates and generates a three-dimensional processing path based on the collected data and controls the grinding module to perform the processing; after processing is completed, the cleaning module cleans and dries the lens.

[0005] Furthermore, the external power adapter directly supplies power to the grinding module, the multi-axis motion control module, and the voltage regulator module.

[0006] Furthermore, the external power adapter provides a voltage of 24V; The voltage regulator module adopts a three-stage non-isolated step-down architecture: the first-stage voltage regulator circuit uses a semiconductor switching regulator to convert 24V to 12V to power the human-machine interaction module and the cleaning module; the second-stage voltage regulator circuit uses a semiconductor switching regulator to convert 24V to 5V to power the data acquisition module; and the third-stage voltage regulator circuit uses a low-dropout linear regulator to convert 5V to 3.3V to power the microcontroller and the data transmission module.

[0007] Furthermore, the grinding module includes two H-bridge driver circuits, which are used to drive the grinding wheel motor and the clamping motor, respectively. The control signal input terminals of the two H-bridge driver circuits are connected to the microcontroller.

[0008] Furthermore, the H-bridge driver circuit for driving the clamping motor has a current sampling function, and its current sampling signal output terminal is connected to the analog-to-digital conversion pin of the microcontroller. The microcontroller realizes feedback control of the lens clamping force by monitoring the sampled current.

[0009] Furthermore, the multi-axis motion control module includes four stepper motor drivers, each using a TMC2209 chip; the four stepper motor drivers are configured with different UART addresses and connected to the same UART serial port of the microcontroller for unified addressing and control.

[0010] Furthermore, the cleaning module includes an image recognition unit, a light adjustment unit, a water pressure control unit, and a drying unit; the microcontroller is configured to execute the following cleaning control logic: after the grinding process is completed, the brightness is adjusted by the light adjustment unit, and the position and size of the grinding debris on the lens surface are identified by the image recognition unit, thereby controlling the water pressure control unit to adjust the water pressure to clean the lens; after cleaning is completed, the brightness is adjusted by the light adjustment unit, and the position and size of the water droplets are identified by the image recognition unit, thereby controlling the airflow of the drying unit.

[0011] Furthermore, the data acquisition module includes an RS485 interface circuit connected to the microcontroller and a displacement sensor interface. The RS485 interface circuit is used to communicate with the grating sensor to acquire lens thickness and curvature data; the displacement sensor interface is used to acquire lens outline data.

[0012] Furthermore, the human-computer interaction module is a serial port screen with capacitive touch function; the microcontroller communicates with the human-computer interaction module through the serial port and synchronously sends the three-dimensional machining path data obtained from the calculation to the human-computer interaction module for display.

[0013] Furthermore, the fully automatic lens grooving and chamfering machine control system also includes a buzzer module, which is connected to the microcontroller. The microcontroller controls the sound frequency of the buzzer to indicate to the user whether the touch is valid, the processing is complete, or the machine is in an abnormal state.

[0014] Compared with the prior art, the beneficial effects of the present invention are: (1) This invention automatically acquires the lens shape dimensions through a data acquisition module and performs three-dimensional path planning by a microcontroller, completely eliminating the random errors caused by manual measurement and experience-based parameter setting in traditional processing. The entire process, from positioning, measurement, planning to processing and cleaning, is fully automated, avoiding manual intervention and pauses between processes, greatly improving production efficiency, and ensuring excellent consistency of product quality in mass production.

[0015] (2) The present invention uses a high-performance microcontroller (STM32F407VET6) with an ARM Cortex-M4 core as the computing core, which is capable of complex real-time path calculation and multi-task scheduling, ensuring the system’s fast response capability.

[0016] The TMC2209 and other high-microstepping, low-noise stepper motor drivers were selected to achieve smooth and precise micro-stepping control. At the same time, the H-bridge driver with integrated current sampling, such as the DRV8872, was used to perform torque feedback control on the clamping motor, realizing precise closed-loop adjustment of the clamping force and effectively preventing damage to the lens due to excessive tightness or insufficient clamping force.

[0017] (3) The multi-axis motion control module adopts UART bus to centrally control four stepper motor drivers, using only one set of serial port resources of the microcontroller, and achieves unified addressing by configuring different addresses. This design greatly simplifies system wiring, reduces hardware complexity and cost, and ensures the synchronization and coordination of multi-axis motion.

[0018] The power module adopts a graded voltage regulation design, providing 12V, 5V and 3.3V power supplies respectively to meet the voltage and noise sensitivity of different modules. This not only ensures the driving capability of high-power components such as motors, but also provides a clean and stable working environment for core devices such as microcontrollers and sensors, thereby fundamentally improving the operational stability and anti-interference capability of the entire system.

[0019] (4) The cleaning module is not a simple rinse, but a closed-loop control system based on visual feedback. The distribution of abrasive and water droplets on the lens surface is dynamically detected by the image recognition unit, and the light contrast, water pressure and drying air volume are intelligently adjusted to achieve "cleaning on demand". This intelligent process not only cleans thoroughly without damaging the lens, but also avoids the waste of water and electricity in the traditional method, achieving a perfect combination of high efficiency, energy saving and reliability.

[0020] (5) The user-friendly human-machine interface (capacitive touch serial port screen) makes parameter setting intuitive and simple, and the processing path can be previewed in real time, reducing the skill threshold and training cost for operators. The rich data transmission interfaces (such as RS232, USB, and wireless modules) provide a foundation for the equipment to connect to the Industrial Internet of Things and realize remote monitoring and production data management, meeting the urgent needs of modern manufacturing for flexible and intelligent production.

[0021] Through the aforementioned comprehensive technical means, this invention has completely changed the traditional lens processing mode that relies on human experience, and realized automated and intelligent production driven by data and algorithms, achieving a leap forward in processing accuracy, production efficiency, operational stability and intelligence level.

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] The present invention will be further described in detail below with reference to the embodiments.

[0025] like Figure 1 As shown, the fully automatic lens grooving and chamfering machine control system of the present invention has a hardware core based on a 32-bit microcontroller 1 with an ARM Cortex-M4 core. In this embodiment, the microcontroller 1 is selected from STMicroelectronics' STM32F407VET6 chip, which has powerful floating-point arithmetic capabilities and rich peripheral interfaces, and can meet the needs of complex path planning and real-time multi-task control.

[0026] The system is powered by an external 100W 24V DC power adapter 2. The main components of the system include a voltage regulator module 3, a grinding module 4, a multi-axis motion control module 5, a human-machine interface module 6, a microcontroller 1, a data transmission module 7, a cleaning module 8, and a data acquisition module 9.

[0027] To ensure stable operation of each module and reduce interference, voltage regulator module 3 adopts a three-stage non-isolated buck architecture: see [link to relevant documentation] Figure 16 The first-stage voltage regulator circuit receives an externally input 24V DC power supply, which is then stepped down to 12V via a switching regulator chip (such as LM2596S-12). This power supply mainly powers the human-machine interface module 6 (serial port screen), the water pump in the cleaning module 8, and the lighting adjustment unit (LED light strip). See also... Figure 17 The second-stage voltage regulator circuit uses a switching regulator chip (such as LM2596S-5.0) to step down the 24V to 5V. This power supply mainly powers the data acquisition module 9 (such as the vision camera) and some communication interface circuits. See also... Figure 18The third-stage voltage regulator circuit uses a low-dropout linear regulator (LDO, such as AMS1117-3.3) to step down the 5V to 3.3V. Because the LDO output ripple is small, this power supply is dedicated to powering core logic devices that are sensitive to power supply noise, such as the microcontroller 1 and the data transmission module 7 (Flash storage, RS485 / 232 conversion chip).

[0028] See Figure 2-8 As shown, the system's control core is a 32-bit microcontroller 1U1 (STM32F407VET6) manufactured by STMicroelectronics. Its minimum system circuit includes: the chip's main logic interface ( Figure 2 ), used to connect various input / output peripherals; power supply pins and analog power supply filtering circuits ( Figure 3 The chip's analog power supply pin VDDA is isolated from the digital power supply VDD via a ferrite bead L3 and is equipped with a decoupling capacitor C17, significantly enhancing the anti-interference capability of the analog circuit; reset circuit ( Figure 4 It consists of resistor R1 and capacitor C2; external crystal oscillator circuit ( Figure 5 The chip is powered by an external 8MHz crystal oscillator Y1 and its load capacitors C1 and C3, which provide a reference clock. The download interface ( Figure 6 ), namely SWD program download interface J1, used for program burning and online debugging; user flash boot circuit ( Figure 7 ), namely the Boot mode selection circuit, used to set the startup mode; digital power supply decoupling capacitor circuit ( Figure 8 (), used to filter digital power supplies.

[0029] like Figure 9-13 As shown, the multi-axis motion control module 5 is responsible for controlling the X, Y, Z axes and rotary axes of the machine. This embodiment uses a four-channel stepper motor driver, which employs the TMC2209 chip. To save resources on the microcontroller 1 and achieve unified management, the four drivers utilize UART bus technology (…). Figure 13 The connection is established through a specific method: the UART receive pins (UART_RX) of the four stepper motor drivers are connected in parallel to the transmit pins (M_UART_TX) of microcontroller 1, and the transmit pins (UART_TX) are each connected to the receive pins (M_UART_RX) of microcontroller 1 via independent resistors. Crucially, a unique UART physical address is assigned to each driver by configuring the pull-down / pull-up resistor combinations (e.g., set to 00, 01, 10, 11 respectively) of the MS1 and MS2 pins of each driver chip. Microcontroller 1 can independently address, configure parameters, and control the motion of the four motors through only one UART interface, achieving precise control with high microstepping, low vibration, and low noise.

[0030] In addition, the multi-axis motion system is also equipped with a zero-position sensor and limit switch interface circuit (see...). Figure 26 (This is used to accurately calibrate the starting position and safety limits of each axis to prevent mechanical collisions.)

[0031] like Figure 14 and Figure 15 As shown, the grinding module 4 includes two H-bridge driver circuits. One H-bridge driver circuit drives the grinding wheel, using a DRV8874 chip (U19) to drive a DC grinding wheel motor. The PA8 and PA9 pins of the microcontroller 1 are connected to the chip's input terminals to control the high-speed rotation and braking of the grinding wheel. This chip has a peak current of up to 5.8A, meeting the grinding power requirements. The other H-bridge driver circuit controls the clamping force, using a DRV8872 chip (U18) to drive a DC clamping motor. To prevent the lens from breaking or the clamping from being loose, the current feedback function of the DRV8872 is utilized. The chip's current sampling output pin IPROP1 is connected to the ADC input pin (PC0) of the microcontroller 1 through an RC filter circuit. The microcontroller 1 collects this voltage value in real time, converts it into motor current, and then calculates the current clamping torque. When the current reaches a preset threshold, the microcontroller 1 immediately stops the motor, thus achieving closed-loop constant force clamping.

[0032] like Figure 19-23 As shown, cleaning module 8 is a closed-loop control subsystem, including an image recognition unit (USB camera), a lighting adjustment unit (LED light strip), a water pressure control unit (water pump), and a drying unit (hot air gun / fan). Its workflow is as follows: During the chip cleaning stage: Microcontroller 1 controls the lighting adjustment drive circuit via the PWM interface (PA10). Figure 21 The brightness of the LED light strip is adjusted to enhance the contrast between the abrasive debris and the lens surface. The image recognition unit connects via a USB interface (…). Figure 20 The image is transmitted back to identify the location and degree of wear debris accumulation. Based on this, microcontroller 1 outputs an analog voltage through the DAC interface (PA4) to control the water pressure regulation control circuit. Figure 19 Adjust the water pump drive circuit to regulate the water pressure and clean the area with abrasive debris.

[0033] Drying Stage: After washing, the system readjusts the lights, and the image recognition unit identifies residual water droplets. Microcontroller 1 controls the circuit via the drying relay ( Figure 22 The drying module is started, and the exhaust fan drive circuit is controlled simultaneously. Figure 23 Adjust the exhaust fan until the lens surface is detected to be dry.

[0034] like Figure 24 and 25As shown, the data acquisition module 9 includes an RS485 communication circuit (using an SP3485 chip) for connecting to a high-precision grating sensor to acquire lens thickness and curvature data. Additionally, it acquires lens outline data via a potentiometer / displacement sensor interface.

[0035] like Figure 27 As shown, the data transmission module 7 includes an RS232 interface, using a MAX3232 chip U3, for connecting to a host PC or debugging equipment to achieve parameter setting, status monitoring, and data export. In addition, the system can also integrate modules such as wireless network and Bluetooth, allowing users to customize external devices according to interface definitions and transmission protocols.

[0036] like Figure 31 As shown, the system is equipped with an external data storage module (Flash chip) for persistent storage of user-defined parameters and processing data.

[0037] like Figures 28 to 30 As shown, the human-computer interaction module 6 uses a serial port screen with capacitive touch function, which is connected via the serial port screen interface circuit ( Figure 28 It communicates with microcontroller 1. The user can input processing parameters on the screen. The system is also equipped with a buzzer module ( Figure 29 This is used to emit different frequencies of prompts when a touch operation is completed, processing is finished, or a system malfunction occurs. The system's real-time time is controlled by an independent real-time clock circuit (…). Figure 30 )maintain.

[0038] The workflow of the fully automatic lens grooving and chamfering machine control system of the present invention is as follows: After the system powers on and completes its self-test, the user sets the processing parameters via the serial port screen. Microcontroller 1U1 controls the multi-axis motion module to move the lens to the data acquisition area. Data acquisition module 9 (camera and sensors) collects the lens's external dimensions and sends it back to U1. U1 calculates the 3D processing path using its built-in algorithm and displays it synchronously on the serial port screen. After user confirmation, U1 coordinates with the multi-axis motion module and grinding module 4 to perform high-precision grooving and chamfering operations. After processing, the lens is sent to the cleaning station, and the intelligent cleaning module 8 starts, completing cleaning and drying based on visual feedback. Finally, the system notifies the user to pick up the part via the serial port screen and a buzzer, completing the fully automated processing cycle.
