Description

Technical Field

[0001] The present invention relates to the field of mechanical automation technology, and is used for the transmission of items requiring precise guidance. A servo motor cooperates with a reduction motor to directly drive a synchronous wheel to drive a belt to perform linear motion, and in particular, relates to a novel linear motion module. Background Art

[0002] The linear motion device is the most common motion mechanism in machinery, and the present invention is also one of the common devices that convert rotation into linear motion. The linear motion device is one of the most commonly used mechanisms in the field of modern mechanical manufacturing, and is widely used in various mechanical equipment, robots, tools and other fields. Existing linear motion mechanisms usually use screw rods, synchronous belts, chains or motor drives, which have the characteristics of high precision, accurate positioning and fast speed. Traditional linear motion mechanisms use different types of drive forms to meet the use requirements according to different usage scenarios and load sizes. For environments that require diverse transportation, the cost increases and the applicability is poor; therefore, we propose a new linear motion module to solve this problem.
