Description

Technical Field

[0001] This utility model relates to the field of machine tool control technology, specifically to a machine tool barcode scanning start control device. Background Technology

[0002] In traditional machine tool operation scenarios, equipment start-up control primarily relies on physical button triggers, password authentication, and key switches. While these traditional start-up methods can achieve basic equipment operation management functions, they exhibit several limitations in practical applications: First, the operation process is significantly inefficient, requiring manual intervention for authorization verification, with redundant steps leading to prolonged equipment response times. Second, password-based identity verification systems have inherent security vulnerabilities; passwords are easily leaked due to human error or technical attacks, and the risk of misoperation is high, making it difficult to guarantee the security and reliability of equipment operation. Third, physical control components are prone to mechanical wear over long-term use, leading to performance degradation and increased failure probability. Furthermore, they cannot provide complete operation records and traceability during equipment use, failing to meet the digital and intelligent development needs of modern intelligent manufacturing for the entire equipment lifecycle management. Utility Model Content

[0003] In view of this, the present invention provides a machine tool scanning start control device to solve the technical problems of traditional machine tool operation, such as cumbersome operation, need for manual confirmation of authorization, low efficiency, easy leakage or misoperation of password, insufficient security, easy wear and tear, inconvenient management, lack of operation record traceability function, and difficulty in meeting the needs of intelligent management.

[0004] To achieve the above objectives, this utility model provides the following technical solution: It mainly provides a machine tool barcode scanning start control device, comprising a scanning module, a main control module, an execution module, and an intelligent alarm module. The scanning module, as the system's front-end data acquisition unit, uses an industrial-grade QR code scanner head, featuring high precision and high reliability. It is used to scan QR codes or barcodes provided by the operator. This module integrates an automatic lighting unit, achieving adaptive light adjustment through an ambient light sensing feedback mechanism. The lighting unit circuit consists of a closed-loop control system composed of a photoresistor RL, an operational amplifier U1, and a transistor Q1.

When the information is verified, the main control module sends start information to the execution module. The execution module adopts a distributed control architecture, configuring independent start-up power control circuits for multiple CNC machine tools. Each control circuit consists of a drive circuit, relays, and AC contactors. If the information verification fails, an alarm signal is sent to the intelligent alarm module. The intelligent alarm module adopts a multi-alarm mechanism of sound and light. The execution module is used to receive the start signal sent by the main control module and control the power circuit of the machine tool. When the execution module receives the start signal, it connects the power circuit of the machine tool to start the machine tool.

[0005] The main control module includes a microcontroller, a memory, a communication module, and an LCD display. The industrial-grade QR code scanner is electrically connected to the microcontroller. The memory, communication module, and LCD display are all electrically connected to the microcontroller. The main control module also has the function of communicating with a host computer to realize remote management and updates.

[0006] The execution module includes multiple sets of startup power control circuits, which are set on the power supply circuit of each CNC machine tool and electrically connected to the microcontroller, thereby controlling the startup of each CNC machine tool.

[0007] The intelligent alarm module includes a buzzer alarm and an LED light assembly. The buzzer alarm is electrically connected to the microcontroller via a control circuit, and the LED light assembly is also electrically connected to the microcontroller.

[0008] Furthermore, the scanning module is equipped with a transparent protective cover.

The other end of the photoresistor RL is connected to one end of resistor R2 and the inverting input of operational amplifier U1. The other ends of resistors R2 and R3 are both connected to a power supply. The other end of resistor R3 is connected to the power supply of resistor R1. The other end is connected to the non-inverting input of operational amplifier U1 and one end of resistor R4. The other end of resistor R4 is connected to the output of operational amplifier U1 and one end of resistor R5. The other end of resistor R5 is connected to one end of resistor R6 and one end of resistor R7. The other end of resistor R6 and the emitter of transistor Q1 are both connected to the power supply.

[0013] As can be seen from the above technical solution, the main advantages of this utility model include:

[0014] 1. This utility model achieves secure and rapid startup through QR code verification and automatic execution, and supports operation record storage. It avoids the traditional startup method that requires manual intervention for authorization verification and redundant operational steps. By using QR code or barcode scanning for identity recognition and authorization verification, operators only need to bring the QR code or barcode close to the scanning module to quickly complete information collection and verification, shortening the equipment response cycle and improving the operational efficiency of machine tool startup. Furthermore, compared to password-based identity recognition systems, QR codes or barcodes offer higher security. In addition, the main control module's camera records the operator's image information, which, combined with the scanned QR code or barcode information, provides a more comprehensive record of the operator's information and operational behavior.

This utility model reduces the use of physical control components, lowers the risk of failure due to mechanical wear, extends the service life of the equipment, and the dual alarm method can more effectively attract the attention of operators and promptly remind them to handle abnormal situations.

[0016] 3. The execution module adopts a distributed control architecture, which can configure independent start-up power control circuits for multiple CNC machine tools, thereby improving control efficiency. Attached Figure Description

[0021] This embodiment provides a machine tool barcode scanning start control device that solves the problems of cumbersome operation and insufficient safety in traditional machine tool start control methods, and is convenient to operate, highly safe, and easy to manage. For example... Figure 1 and Figure 2As shown, this machine tool barcode scanning start control device consists of several key modules working together, closely interconnected. Specifically, it includes a scanning module, a main control module, an execution module, and an intelligent alarm module. It employs an industrial-grade QR code scanner, characterized by high precision and reliability, used to scan QR codes or barcodes provided by the operator. This module integrates an automatic lighting unit, achieving adaptive light adjustment through an ambient light sensing feedback mechanism. The main control module includes a microcontroller, memory, communication module, and LCD display. The industrial-grade QR code scanner is electrically connected to the microcontroller, transmitting the scanned information to the main control module. The execution module is electrically connected to the main control module. When the information verification is successful, the main control module sends start information to the execution module. The execution module adopts a distributed control architecture, configuring independent start-up power control circuits for multiple CNC machine tools. Each control circuit consists of a drive circuit, relays, and AC contactors. The execution module receives the start signal sent by the main control module and controls the on / off state of the machine tool's power circuit. When the execution module receives the start signal, it connects the machine tool's power circuit, starting the machine tool. The memory, communication module, and LCD display are all electrically connected to the microcontroller. The communication module includes an industrial bus module, a 4G / 5G wireless communication module, and a ZigBee network module. If information verification fails, an alarm signal is sent to the intelligent alarm module. The intelligent alarm module employs a multi-mode alarm mechanism, including a buzzer and LED lights. The buzzer and LED lights are electrically connected to the microcontroller via a control circuit.

[0022] In this embodiment, an industrial-grade QR code scanner, model DM3700, is used. It features high precision and reliability, supports mainstream code recognition such as QRCode and DataMatrix, and achieves a scanning accuracy of up to 5 mil. The scanning module also integrates an automatic illumination unit, achieving adaptive light adjustment through an ambient light sensing feedback mechanism. The scanner head adopts an IP65 protection rating design, with an external high-strength acrylic transparent protective cover, effectively resisting the intrusion of industrial contaminants such as cutting fluid and dust, ensuring stable operation under harsh conditions. The main control module uses an STM32F745VET6 controller chip and an AT24C256 high-capacity EEPROM with a storage capacity of 32KB, used to store system configuration parameters and operation logs, supporting 1 million erase / write cycles. The LCD display is a 3.5-inch TFT color LCD screen (320×240 resolution), combined with a 4×4 matrix keypad for parameter setting and status display functions. The main control module's camera module, OV7670 (640×480 resolution), supports image recording during operation. The communication module integrates multiple redundant communication interfaces. Among them, the industrial bus interface supports Modbus RTU and Profibus-DP protocols, with a communication rate of up to 12Mbps; the wireless communication interface has a built-in 4G / 5G communication module (model: EC200S), which supports multiple network standards such as LTE-FDD / LTE-TDD / WCDMA / GSM, and also integrates a ZigBee wireless module (model: CC2530) to support Mesh self-organizing network communication.

[0023] The intelligent alarm module includes a buzzer and LED lights. The buzzer uses an SFM-27 buzzer with a working voltage of 5V, and the LED lights are RGB tri-color LED warning lights with red, yellow, and green display functions. The control circuit is based on a 74HC595 shift register to expand the I / O ports, enabling parallel control of multiple alarm signals.

[0024] In this embodiment, the main control module also includes a setting button and a power module. The setting button is electrically connected to the microcontroller and is used to set startup delay parameters, etc. The power module is used to output the voltage required by each module of the device. It adopts a multi-stage power conversion architecture, supports a wide voltage range of 18-36VDC for input power, and has built-in overvoltage, overcurrent, and reverse connection protection circuits. It can output 12V, 5V, and 3.3V DC voltage.

[0025] like Figure 2As shown, the lighting unit circuit consists of a closed-loop control system composed of a photoresistor RL, an operational amplifier U1, and a transistor Q1. When the ambient light intensity is lower than the threshold (200 lux), the change in the resistance of the photoresistor triggers the operational amplifier to output a high level, driving the transistor to conduct and causing the relay K1 to engage, automatically turning on the LED supplementary light group; when the light intensity returns to normal, the system automatically cuts off the lighting circuit.

[0026] Specifically, the lighting unit includes a photoresistor RL, resistors R1, R2, R3, R4, R5, R6, and R7, a transistor Q1, an operational amplifier U1, a diode D1, and a first relay. One end of the photoresistor RL is connected to one end of resistor R1 and then grounded. The other end of the photoresistor RL is connected to one end of resistor R2 and the inverting input of operational amplifier U1. The other ends of resistors R2 and R3 are both connected to the power supply. The other end of resistor R3 is connected to the other end of resistor R1 and the non-inverting input of operational amplifier U1. One end of resistor R4 is connected to the output terminal of operational amplifier U1, and the other end of resistor R4 is connected to one end of resistor R5. The other end of resistor R5 is connected to one end of resistor R6 and one end of resistor R7. The other end of resistor R6 and the emitter of transistor Q1 are both connected to the power supply. The other end of resistor R7 is connected to the base of transistor Q1. The collector of transistor Q1 is connected to the cathode of diode D1 and one end of the first relay. The anode of diode D1 and the other end of the first relay are grounded. The first relay controls the on / off state of the LED lighting. When the ambient illuminance drops to the set value, the resistance of the photoresistor increases, causing the potential at the inverting input of operational amplifier U1 to rise. Its output excites transistor Q1 to conduct. The excitation current of transistor Q1 causes the relay to operate, closing the normally open contact and opening the normally closed contact, thereby controlling the LED lighting and achieving auxiliary lighting.

[0027] In this embodiment, a cloud server is also included. The microcontroller is electrically connected to the cloud server through a communication module, and the main control module communicates with the cloud server using the MQTT protocol.

[0028] The execution module adopts a distributed control architecture, configuring independent startup power control circuits for multiple CNC machine tools. Specifically, multiple startup power control circuits are set on the power supply circuit of each CNC machine tool, and are electrically connected to the microcontroller to control the startup of each CNC machine tool. Each startup power control circuit includes a second relay and a drive circuit. The control terminal of the drive circuit is electrically connected to the signal output terminal of the microcontroller, and the output terminal of the drive circuit is electrically connected to the control terminal of the second relay. The second relay is electrically connected to a contactor. Each control circuit consists of a Darlington transistor drive circuit, an SRD-05VDC-SL-C relay, and an LC1-D18 AC contactor. The TTL control signal output by the microcontroller is optocoupled and then drives the ULN2003A, thereby controlling the on / off state of the relay coil. The relay contacts control the contactor coil, ultimately achieving reliable on / off control of the 380V / 50Hz machine tool main power supply.

[0029] The working principle of this device is as follows:

[0030] Operators use mobile phones or other scanning devices to scan the provided QR codes or barcodes. After scanning, the scanning module transmits the information to the main control module. The main control module, upon receiving the information, sends a start signal to the execution module. If the information verification fails, an alarm signal is sent. Upon receiving the start signal, the execution module connects the machine tool's power circuit, starting the machine tool. Upon receiving a stop signal or alarm signal, it disconnects the machine tool's power circuit, stopping the machine tool. The main control module has the function of communicating with a host computer, which can be connected via wired or wireless means. The host computer can send valid QR code / barcode information to the scanning module for remote management and updates. The main control module can also upload the machine tool's operating status to the host computer for remote monitoring.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the embodiments of the present utility model.
