(1) Sewing equipment of the linear actuator
Over the past 100 years, people have continuously improved and innovated the sewing machine(linear actuator), from ordinary pedal household sewing machine to multi-functional industrial sewing machine. After entering the 1960s, the development of sewing machine began to apply electronic technology, and electromechanical integrated sewing machine appeared. This new type of sewing machine uses controllable motor and microprocessor to control the sewing process, which improves the flexibility of sewing machine. At present, the development of sewing equipment in the direction of electromechanical combination has been the consensus of people in the industry. Many people believe that in order to make the actions of the four mechanisms, the horizontal needle mechanism and the thread cutting mechanism "arbitrary", such as arbitrarily changing the behavior of the needle rod, the trajectory of the thread take-up hole and the action of the horizontal needle, only using the "traditional mechanism" is powerless, and we must turn to the "electromechanical motion technology" to improve the performance of the sewing equipment.
(2) Camera focusing system of the linear actuator
The camera is composed of lens, shutter, aperture, focusing device, viewfinder, film rolling mechanism and box body. Due to the wide application of mechatronics technology in this field, a large number of complex mechanisms have been replaced by integrated circuits, driving motors and electromagnetic actuators. The camera has developed from the traditional product of the combination of precision machinery and optics to the automation system of the integration of precision machinery, optics and microelectronics technology.(linear actuator)
