Description

Technical Field

[0001] This utility model relates to the field of glass coating technology, specifically a coating positioning precision device. Background Technology

[0002] Glass coating is a technique that involves coating a glass surface with special chemical materials to alter its properties by forming one or more extremely thin protective films on the glass surface.

[0003] In the glass disk coating process, the way the worktable is fixed has a decisive impact on the coating accuracy and uniformity. Traditional coating equipment often places the glass disk directly on the worktable surface, a simple placement method with obvious technical limitations. Due to the lack of an effective positioning and fixing mechanism, the glass disk is prone to micro-displacement during the coating process due to equipment vibration, airflow disturbance, or mechanical transmission. This micron-level displacement leads to uneven film thickness distribution, especially at the edges where film thickness gradients are likely to occur, severely affecting the consistency of optical performance. At the same time, a statically placed glass disk cannot be rotated, meaning that the coating material can only be deposited along a fixed direction, making it difficult to ensure the uniformity of complex film structures at various azimuth angles.

[0023] 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.

[0024] Please see Figures 1 to 7 The present invention provides two embodiments:

[0025] Example 1: A precise positioning device for coating includes a base 1, a glass plate 6, and a rotating rod 33. A fixing rod 15 is fixed to the upper surface of the base 1. The top of the fixing rod 15 is rotatably connected to a rotating rod 10. A gear 9 is fixed to the rotating rod 10. A fixing plate 8 is fixed to the fixing rod 15. A rotating shaft 12 is rotatably connected to one side of the upper surface of the fixing plate 8. A gear 11 is fixed to the top of the rotating shaft 12. Gear 9 and gear 11 mesh with each other. A circular box 4 is fixed to the top of the rotating rod 10. A circular groove 5 is formed on the upper surface of the circular box 4. A circular ring 22 is fixed to the lower surface of the circular box 4. A through hole 23 is formed on the upper surface of the circular ring 22. 2. A long plate 2 is fixed to the outer wall. A long groove 19 is opened on the upper surface of the long plate 2. A connecting block 21 is inserted into the long groove 19. A motor 2 17 is fixed to the front end of the long plate 2. A screw 20 is fixed to the rear end of the transmission shaft of the motor 2 17. The rear end of the screw 20 passes through the connecting block 21 and is threaded. A movable plate 3 is fixed to the upper surface of the connecting block 21. The movable plate 3 is rotatably connected to the rotating rod 2 33. A movable rod 25 is installed at the rear end of the rotating rod 2 33. The rear end of the movable rod 25 passes through the round box 4 and extends into the round groove 5. A limit frame 28 is fixed to the rear end of the movable rod 25. A rubber pad 27 is fixed inside the limit frame 28. The rubber pad 27 is in contact with the glass plate 6.

[0026] The upper surface of the fixing plate 8 is provided with a mounting hole 7, the top end of the fixing rod 15 passes through the mounting hole 7, and the outer wall of the fixing rod 15 is fixed to the inner wall of the mounting hole 7.

[0027] A circular hole 13 is provided on the lower surface of the fixing plate 8. A motor 14 is fixed on the lower surface of the fixing plate 8. The top end of the transmission shaft of the motor 14 extends into the circular hole 13. A rotating shaft 12 is fixed on the top end of the transmission shaft of the motor 14.

[0028] Motor 14 is an AC motor. An AC motor is a device that converts alternating current electrical energy into mechanical energy. Its basic structure mainly consists of two parts: the stator and the rotor. The stator is the stationary part, while the rotor is the rotating part. The stator is made of laminated silicon steel sheets and has windings embedded inside. When alternating current is applied, it generates a rotating magnetic field.

[0029] The working principle of an AC motor is based on the interaction of electromagnetic induction and a rotating magnetic field. When three-phase alternating current is applied to the stator windings, a rotating magnetic field is generated inside the motor. The rotational speed of this rotating magnetic field is called the synchronous speed, and its magnitude is determined by the power supply frequency and the number of poles of the motor. The rotor conductors cut magnetic lines of force in the rotating magnetic field, generating induced electromotive force and induced current. The charged rotor conductors are subjected to electromagnetic force in the magnetic field, thereby generating electromagnetic torque to drive the rotor to rotate.

[0030] In this embodiment, when it is necessary to coat the glass disk 6, the glass disk 6 is fixed in place, and then the motor 14 is started, so that the gear 9 and gear 11 can rotate as needed. At the same time, the rotating rod 10, the round box 4 and the glass disk 6 can rotate as needed. Then, the coating device is used to coat the rotating glass disk 6, which achieves the effect of facilitating the rotation of the glass disk 6 and making it convenient to coat the glass disk 6.

[0031] Example 2:

[0032] The connecting block 21 has a threaded hole 24 at its front end, the long plate 2 has a round hole 18 at its front end, and the motor 2 has a screw 20 fixed at the rear end of its transmission shaft. The rear end of the screw 20 passes through the threaded hole 24 and is threadedly connected.

[0033] Three motors, number 2.17, are selected as servo motors. Servo motors are high-precision, high-response motors capable of quickly and accurately adjusting speed, torque, and position based on control signals. They consist of three main parts: the motor body, the encoder, and the controller, forming a closed-loop control system. The motor body typically uses a permanent magnet synchronous motor or a brushless DC motor structure, with three-phase windings wound on the stator core and a rotor constructed from high-performance permanent magnets. The encoder, serving as a position and speed detection element, is installed at the rear of the motor and can be photoelectric, magnetoelectric, or a rotary transformer, used to provide real-time feedback of the rotor's actual position information.

[0034] The working principle of a servo motor is based on precise adjustment through closed-loop control. When the controller receives a position, speed, or torque command, it compares it with the actual value fed back by the encoder. The resulting error signal is processed by a PID algorithm to generate the corresponding control quantity.

[0035] Three motors (217) are controlled by an electronic synchronizer, enabling them to rotate at the same speed. The electronic synchronizer is a multi-motor cooperative drive system based on closed-loop control principles. It achieves precise synchronous operation of the three motors through real-time monitoring and dynamic adjustment. The system mainly consists of a main control unit, a power drive module, a high-precision encoder, and a high-speed communication network. The main control unit typically uses a high-performance digital signal processor or an industrial-grade PLC as its core, responsible for running the synchronization control algorithm and processing real-time data from each node. The power drive module contains three independent inverter circuits, which can adjust the power supply parameters of each motor individually. High-resolution encoders are directly mounted on the shaft of each motor, detecting actual speed and position information at a microsecond-level sampling frequency.

[0036] Its working principle is embodied in a precise feedback adjustment process. During system operation, the main control unit first sets the target speed as the synchronization reference. The encoders equipped on the three motors continuously collect the actual speed signals and upload them through the communication network. An advanced multi-axis synchronous control algorithm compares the speeds of each motor in real time. When a speed deviation is detected in a motor due to load changes, the system immediately calculates the required torque compensation. The main control unit dynamically changes the drive current of the motors by adjusting the PWM output waveform of the corresponding inverters, causing lagging motors to accelerate or leading motors to decelerate. This adjustment process is executed cyclically with a millisecond-level response speed, forming a closed-loop control, thereby ensuring that the three motors maintain strict speed synchronization under any operating conditions.

[0037] The front end of the movable plate 3 has a second mounting hole 37, in which a bearing 34 is installed. The front end of the rotating rod 33 is fixed with a turntable 32, and the rear end of the rotating rod 33 passes through the bearing 34 and is rotatably connected. The rear end of the rotating rod 33 is fixed with a threaded post 35. The front end of the movable rod 25 has a threaded groove 36, and the threaded post 35 extends into the threaded groove 36 and is threadedly connected.

[0038] A through hole 31 is provided on the outer wall of the round box 4. A guide tube 16 is fixed on the outer wall of the round box 4. A pipe hole 26 is provided at the front end of the guide tube 16. The rear end of the moving rod 25 extends into the round groove 5 through the pipe hole 26 and the through hole 31.

[0039] A support rod 30 is fixed to the bottom of the inner wall of the circular groove 5, and a support plate 29 is fixed to the top of the support rod 30. The upper surface of the support plate 29 is in contact with the lower surface of the glass plate 6.

[0040] In this embodiment, when it is necessary to coat the glass disk 6, the glass disk 6 is placed on the support disk 29, and then the motor 17 is started, causing the screw 20 to rotate. The connecting block 21, the moving plate 3, the moving rod 25, and the limiting frame 28 can move as needed, so that the rubber pad 27 can fit against the side wall of the glass disk 6, allowing the glass disk 6 to be clamped and limited from multiple directions. This achieves the effect of facilitating the clamping and limiting of the glass disk 6, ensuring stable clamping and limiting of the glass disk 6, and ensuring accurate coating of the glass disk 6.

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.
