Precise positioning technology is one of the fundamental technologies supporting the high precision and high speed of modern manufacturing equipment, measuring equipment, and high-density intelligence machines. It is also one of the criteria for judging high-quality linear modules. Therefore, linear modules adopt a reasonable positioning structure design to achieve high precision. Let's take a closer look.
1. High-precision motion reference: High-precision motion is generally determined by the motion reference data of mechanical motion. In a stable linear module, the motion reference of the servo electric cylinder can be composed of guide rail elements. When sensors are used to measure and compensate for motion errors, the mechanical system of the linear module, such as a steel ruler, becomes the data of the measurement target. Therefore, manufacturers will use the shape accuracy of the height as the reference of the linear module and the linear motor to improve its motion accuracy.
2. Reasonable motion organization planning: A high-precision motion reference is essential, but a reasonable motion organization plan is also necessary to perfectly coordinate with it and achieve high precision. Therefore, during manufacturing, the linear module considers the influence of internal and external forces, as well as the effects of elastic and plastic deformation and friction of the parts. The miniature electric steel rationally plans the component equipment and structure of the motion system to ensure that shape errors do not occur.
3. Correct motion sensor system detection: Even with correct motion references and organization, a sensor system capable of accurately detecting motion is necessary to ensure the motion accuracy of the linear module. Therefore, the linear module will reflect the displacement signal of the moving part to the control system, forming a closed-loop control, with a single-axis arm to measure and correct the positioning accuracy of the moving body.
Precision is a crucial parameter for linear modules, so companies should research which manufacturers offer the best manufacturing processes when purchasing them. Excellent manufacturing processes are essential for producing high-quality linear modules. After purchase and installation, the orthogonal robot can enhance the precision of the production equipment, resulting in more reliable product quality.
