Precision positioning technology is one of the basic technologies that support the realization of high precision and high speed in today's manufacturing equipment, measurement equipment and high-density intelligence machines, and is also one of the criteria for judging high-quality linear modules. Therefore, the linear module adopts a reasonable position positioning mechanism design, so that it can achieve high precision. Let's have a detailed understanding with the linear module manufacturer.

1. High-precision motion benchmark

High-precision motion is usually determined by the motion reference data of mechanical motion. In linear modules with stable performance, the motion reference can be composed of guide rail elements. When sensors are used to measure and compensate for motion errors, the linear module The mechanical system, such as steel ruler, will become the data of the measurement object, so the manufacturer will use the high degree of shape accuracy as the benchmark of the linear module in order to improve its motion accuracy.

2. Reasonable motion mechanism design

With high-precision motion datum, it is also necessary to have a reasonable motion mechanism design, so as to cooperate with the motion datum to achieve high precision. Therefore, the linear module will consider the influence of internal force and external force, as well as the influence of elastic plastic deformation and friction of parts, and reasonably design the component configuration and structure of the motion system to ensure that no shape error occurs.

3. Correct detection of motion sensor system

Even with the correct motion datum and mechanism, a sensor system that can correctly detect motion is required to ensure the motion accuracy of the linear module. Therefore, the linear module will feed back the displacement signal of the moving body to the control system to form a closed-loop control to measure and correct the positioning target accuracy of the moving body.

Accuracy is a crucial parameter for linear modules, so companies should learn more about which process is better for linear modules when purchasing, because good manufacturing processes can produce high-quality linear modules. In this way, after the purchase and installation, the production equipment can be obtained with higher precision and the production quality of the product can be more reliable.
