Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1 to 6 The present invention provides two embodiments:
[0022] Example 1: Ultra-thin glass appearance defect detection equipment includes a work frame 2, a disc 4, a connecting plate 7 and a glass disc 15. The front end of the work frame 2 is provided with a groove 3. Four pillars 1 arranged in a rectangular array are fixed on the lower surface of the work frame 2. The four pillars 1 can support the work frame 2, so that the whole device is placed stably.
[0023] The rear end of the inner wall of the groove 3 is rotatably connected to the rotating rod 9. The rear end of the work frame 2 is provided with a round hole 10. The rear end of the work frame 2 is fixed with a motor 8. The front end of the transmission shaft of the motor 8 extends into the round hole 10. The front end of the transmission shaft of the motor 8 is fixed with the rotating rod 9. The rotating rod 9 is fixed by the transmission shaft of the motor 8, which provides power for the rotation of the rotating rod 9 and the turntable 14, so as to facilitate the rotation of the glass plate 15 for testing. The front end of the rotating rod 9 is fixed with the turntable 14. The front end of the turntable 14 is fixed with a pressure detection belt 16. The front end of the pressure detection belt 16 is equipped with a rubber ring 17.
[0024] Motor 18 uses an AC motor, which is a device that converts alternating current electrical energy into mechanical energy. Its core structure consists of two main parts: the stator and the rotor. The stator is the stationary part of the motor, usually made of laminated silicon steel sheets, with windings embedded inside. These windings are arranged in a certain pattern, and when alternating current is applied, they generate a rotating magnetic field. The rotor is the rotating part of the motor, installed inside the stator, supported by bearings, and can rotate freely.
[0025] A fixing block 13 is fixed to the side wall of turntable 2 14. Three fixing blocks 13 are fixed in a circular array on the side wall of turntable 2 14. Long plates 5 are fixed to the front ends of the three fixing blocks 13 respectively. The three long plates 5 are fixed by the three fixing blocks 13 respectively, so that three connecting plates 7 are installed on the three long plates 5. At the same time, the three connecting plates 7 are connected to the disc 4, so that the disc 4 is installed stably. The front end of the fixing block 13 is fixed to the long plate 5. The long plate 5 has a long groove 21. The width of the long groove 21 is matched with the width of the connecting block 20. By matching the width of the long groove 21 with the width of the connecting block 20, the long groove 21 can limit the movement of the connecting block 20. The connecting block 20 is inserted into the long groove 21. Motor 2 11 is fixed to the front end of the long plate 5. A screw 18 is fixed to the rear end of the drive shaft. The rear end of the screw 18 passes through the connecting block 20 and is threaded. The front end of the connecting block 20 has a threaded hole 19. The front end of the long plate 5 has a second round hole 22. A second motor 11 is fixed to the front end of the long plate 5. The rear end of the drive shaft of the second motor 11 extends into the second round hole 22. The rear end of the drive shaft of the second motor 11 is fixed with a screw 18. The rear end of the screw 18 passes through the threaded hole 19 and is threaded. The screw 18 is fixed by the drive shaft of the second motor 11, which provides power for the rotation of the screw 18. This allows the disc 4 and the turntable 6 to rotate as needed, which is convenient for clamping the glass disc 15 and for inspecting the side wall of the glass disc 15. The connecting block 20 is fixed to the connecting plate 7, and the connecting plate 7 is fixed to the disc 4.
[0026] Three motors, number 211, are selected as servo motors. Servo motors are high-precision motors capable of quickly and accurately adjusting speed and position based on control signals, and are widely used in automation control, robotics, CNC machine tools, and other fields. Their structure mainly consists of three parts: the motor body, the encoder, and the control driver. The motor body typically uses a permanent magnet synchronous motor or a brushless DC motor. The stator consists of multi-phase windings that generate a rotating magnetic field when energized; the rotor uses high-performance permanent magnet materials, such as neodymium iron boron, to enhance the magnetic field strength and improve response speed. The encoder, acting as a position and speed sensor, detects the rotor position in real time and feeds it back to the control system, forming a closed-loop regulation to ensure motion accuracy. The servo driver receives pulse or analog signals from the host computer and, combined with encoder feedback, dynamically adjusts the current magnitude, frequency, and phase of the motor windings through complex control algorithms, thereby precisely controlling torque, speed, and position. The core of the servo motor lies in closed-loop control, which can compensate for load changes and external disturbances in real time, achieving rapid start-stop, precise positioning, and stable operation.
[0027] The three motors (211) are synchronized, enabling them to rotate at the same speed. A synchronizer is a control device used to coordinate the speeds of multiple motors. Its core objective is to ensure that multiple motors maintain synchronous operation under load changes or external disturbances through real-time monitoring and dynamic adjustment. The synchronizer typically consists of three main parts: a main control unit, a speed detection module, and a power drive module. The main control unit, as the core of the system, is responsible for receiving the set speed and processing real-time feedback signals from each motor. It generally uses a high-performance microprocessor or a dedicated motion control chip to implement complex algorithms. The speed detection module usually consists of an encoder or tachometer mounted on the shaft of each motor. It can accurately capture changes in rotor position and speed and transmit these analog or digital pulse signals to the main control unit. The power drive module adjusts the voltage, current, or frequency supplied to each motor according to control commands. In AC motor systems, frequency converters are often used, while in DC or servo systems, PWM modulation is used to control the drive circuit.
[0028] Its working principle is essentially an extension of closed-loop control. The main control unit first compares the deviations of the feedback signals of each motor with the set values, and then calculates the compensation amount through control algorithms such as PID. When the speed of a motor decreases due to a sudden change in load, the synchronizer will immediately increase the drive power of that motor, while appropriately adjusting other motors to maintain overall synchronization.
[0029] The rear end of the disc 4 is rotatably connected to the rotating rod 12. The rear end of the rotating rod 12 is fixed with the turntable 6. The rear end of the turntable 6 is fixed with the pressure detection belt 16. The rear end of the pressure detection belt 16 is equipped with a rubber ring 17. The glass disc 15 is located between the turntable 6 and the turntable 14.
[0030] The rubber ring 17 is used to protect the clamped glass disk 15 and prevent excessive clamping force from damaging the glass disk 15. The pressure detection band 16 can detect the clamping force and prevent excessive clamping force from damaging the glass disk 15.
[0031] The pressure sensing strip 16 is a flexible sensing device capable of measuring distributed pressure or pressure distribution on a contact surface. Its structure mainly consists of a flexible substrate, a pressure-sensitive layer, an electrode array, and a signal processing circuit. The flexible substrate is typically made of elastic materials such as polyester film or silicone, ensuring the sensing strip can bend and conform to the surface being measured. The pressure-sensitive layer is a key component, made of piezoresistive or piezoelectric materials; its resistance or charge characteristics change with the magnitude of pressure when subjected to external force. The electrode array is arranged in a row-column matrix on both sides of the sensitive layer, forming multiple independent pressure sensing units. The signal processing circuit is responsible for scanning the signal changes of each sensing unit and converting the pressure distribution into a digital matrix output through analog-to-digital conversion.
[0032] The working principle is based on the piezoresistive or piezoelectric effect. When pressure is applied to the surface of the sensing strip, the microstructure of the sensitive layer material deforms, resulting in a change in resistance or the generation of a weak charge. The electrode array sequentially detects the changes in the electrical parameters of each sensing unit in a high-speed scanning manner. The signal processing circuit converts these changes into corresponding pressure values, ultimately constructing a two-dimensional pressure distribution map of the entire detection area.
[0033] When it is necessary to inspect the sidewall of the glass disk 15, the glass disk 15 is placed between turntable 6 and turntable 14. Then, motor 11 is started, causing screw 18 to rotate. Connecting block 20, connecting plate 7, disc 4, and turntable 6 can be moved as needed, so that the rubber rings 17 at both ends clamp and limit the glass disk 15. Motor 8 is then started, causing rotating rod 9, turntable 6, and turntable 14 to rotate as needed. At the same time, the glass disk 15 can rotate as needed. Finally, the glass defect detection device is used to inspect the sidewall of the glass disk 15. This achieves the effect of facilitating comprehensive inspection of the sidewall of the glass disk 15, saving time and effort, and improving work efficiency.
