Description

Technical Field

[0001] The invention relates to the technical field of industrial automation, in particular to a stable encoder soft connector. Background Art

[0002] Encoders, also known as code disks, are widely used in the field of industrial automation because of their ability to convert angular displacement into electrical signals. They are usually used to measure the speed or angle of motors and are irreplaceable. The measurement accuracy and service life of encoders are related to the site environment and installation method in addition to their own quality. For encoders of the same quality, their installation method directly determines their service life. Usually, the installation method of encoders has the following disadvantages: ① Poor stability: Encoders are precision instruments, and their performance and service life are affected by the installation method; encoders and drive shafts are often hard-connected, and the drive shaft vibrates when rotating, damaging the encoder. ② Large vibration: The installation method of encoders is fixed because they are connected with their transmission equipment, such as motor encoders, or installed on motor shafts, or installed on other mechanical transmission adapters. The motor itself vibrates during operation, and the encoder attached to it also has mechanical vibration. ③ Large movement: In addition to vibration from the circumferential direction, the encoder is also affected by axial movement; the center axis of the encoder does not coincide with the center line of the drive shaft, and the encoder is affected by the eccentric force of the drive shaft when rotating, causing mechanical movement in the axial direction. ④Poor redundancy: Production equipment is generally equipped with one encoder. For equipment with high control accuracy requirements, when the encoder fails, there is no spare encoder to switch to, resulting in downtime.

[0003] The measurement accuracy of the encoder directly affects the control accuracy. If the installation of the encoder cannot solve the mechanical vibration and mechanical movement, it cannot provide accurate speed matching and angle positioning for the control system. Summary of the invention

[0042] When measuring the motor speed or angle, the external mechanical structure can drive the base panel 105 to rotate around the fixed axis 105b, and then drive the connecting rod 103 to rotate through the damping connecting shaft 104. Finally, the speed or angle is measured by the encoder. In this process, the mechanical vibration caused by the rotation of the motor and the base panel 105 is eliminated by the damping connecting shaft 104 before being transmitted to the connecting rod 103. The present invention also arranges two encoders to operate simultaneously, thereby improving the system redundancy. The encoder is installed in the soft connector and is independent of the main device.
