Application of Dingge synchronous belt linear module in the electronic manufacturing industry

1、working principle

The operation of the Dingge synchronous belt linear module relies on a precise transmission mechanism. The power source is generally a servo motor or a stepper motor, which drives the driving wheel to rotate. The inner surface of the synchronous belt has a specific tooth profile that meshes with the tooth grooves of the driving wheel and the driven wheel, thereby smoothly converting the rotational motion of the motor into linear motion. A slider is fixed at a specific position on the synchronous belt, and the load is mounted on the slider. When the synchronous belt moves, the slider and the load undergo linear displacement, achieving positioning and linear conveyance. To ensure that the synchronous belt is always in working condition, the module is equipped with a tension adjustment device. By adjusting the tightness of the synchronous belt, slipping is prevented, ensuring the stability and accuracy of power transmission, and enabling the entire system to operate continuously and reliably. For example, in the process of mounting electronic components, the motor drives the driving wheel, which, through the synchronous belt, drives the mounting head on the slider to move to a designated position for mounting operations

2、main components

1. power system：Primarily composed of servo or stepper motors, it serves as the power source for the entire module. The performance of the motor directly determines key indicators such as the module's operating speed, acceleration, and positioning accuracy. High-performance servo motors can achieve more precise speed and position control, making them suitable for electronic manufacturing scenarios where high precision is required。
2. Transmission assembly：Including timing belts, pulleys, and couplings. As the core transmission component, the quality and tooth profile accuracy of the timing belt directly affect transmission efficiency and positioning accuracy; pulleys are divided into driving pulleys and driven pulleys, responsible for transmitting power; couplings are used to connect the motor shaft with the driving pulley, ensuring the coaxiality of power transmission, reducing vibration and deviation, and ensuring the smoothness of the transmission process。
3. guidance system：It is composed of a linear guide rail and a slider. The linear guide rail provides precise guidance for the slider's movement, ensuring the straightness and smoothness of the motion trajectory, so that the load is not disturbed by external factors during movement, achieving high-precision linear motion. At the same time, the linear guide rail has low friction characteristics, which can effectively reduce the resistance during the slider's movement, improving the smoothness and efficiency of the motion。
4. control unit：It encompasses motors (servo or stepper), photoelectric switches, and tension adjustment devices. The motor provides power, while the photoelectric switch detects the position of the slider to achieve positioning control. When the slider moves into the sensing area of the photoelectric switch, the switch emits a signal, and the control system can precisely control the movement of the module based on this signal, such as positioning, starting, and stopping operations. The tension adjustment device adjusts the tension of the timing belt in real time to ensure stable system operation and avoid transmission issues caused by improper tension。
5. frame structure：Generally, aluminum alloy profile frames are used, which not only provide a foundation for the installation of other components, but also ensure the structural stability of the module while reducing the overall weight, facilitating installation and debugging, and improving the overall mobility of the equipment
