Description

Technical Field

[0001] The present application relates to the technical field of linear modules, and in particular to a high-protection double-slide linear module. Background Art

[0002] A linear module is a mechanical device that achieves linear motion. It primarily consists of guide rails, sliders, ball screws (or synchronous belts), motors, and drivers. The guide rails and sliders provide guidance, ensuring linear accuracy. The ball screw or synchronous belt converts the motor's rotational motion into linear motion. The motor provides power, while the driver controls its operation. In automated production lines, linear modules perform tasks such as handling and assembly, helping to improve production efficiency and quality. They also play a key role in achieving precise linear motion in CNC machine tools, semiconductor equipment, medical devices, robotics, and other fields.

[0003] However, the prior art still has the following problems:

[0004] The linear modules of the existing technology usually cannot guarantee accurate precision while having good stability. Some existing linear modules may adopt a single transmission method, such as screw transmission. When running at high speed or using for a long time, vibration is prone to occur, resulting in unstable transmission, affecting the operation accuracy and reliability of the equipment. In addition, the existing linear modules may only rely on simple structures for support and cannot provide sufficient stability for the moving parts. When bearing large loads, they are prone to deformation or shaking, affecting the accuracy and smoothness of the movement.

[0005] In response to the above-mentioned related technologies, the inventors proposed a high-protection double-slide linear module to solve the above-mentioned problems. Utility Model Content

Support grooves 26 are provided on both sides of the upper end of the shell 1, and the lower end of the movable plate 4 is in active contact with the support groove 26, further ensuring the stability of the movement of the movable plate 4. After the motor 22 is started The output end drives one of the pulleys 2 to rotate. Since the two corresponding pulleys 2 are connected by a connecting shaft 23, and a reinforcing shaft 25 is fixedly sleeved on the outer surface of the connecting shaft 23, the two pulleys 2 on one side rotate synchronously. The rotation of the pulley 2 drives the synchronous belt 21 to move, and the connecting block 24 on the synchronous belt 21 moves accordingly. The connecting block 24 drives the movable plate 4 to move, forming a driving mechanism of the linear module. The overall structural design is simple and reliable.

The overall structural design is simple and reliable to use. The transmission mode of two synchronous belts 21 and pulleys 2 is adopted, and the transmission is stable and accurate. The motor 22 drives the pulley 2 to rotate, and the power is transmitted to the connecting block 24 and the movable plate 4 through the synchronous belt 21 to realize linear motion.
