Embodiment Construction

[0039] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments:

[0040] During the assembly process of the ultrasonic motor, the assembly of the terminals and the PCB board often requires manual participation due to the high precision and small structure, which is not conducive to the industrialization and integration of the ultrasonic motor. The effect of manual assembly and welding is affected by many factors, and the production effect of ultrasonic motor products is often unstable.

[0041] To solve the above problems, this example discloses a machine vision-based multi-point positioning assembly mechanism for an ultrasonic motor and a method thereof.

[0042] like Figure 1-6 As shown, the multi-point positioning assembly mechanism of ultrasonic motor based on machine vision includes welding actuator 1, ultrasonic motor part grabbing manipulator 2, frame 3, visual inspection and information se...

Abstract

The invention proposes a machine vision-based multi-point positioning assembly mechanism for ultrasonic motors and its method, including a welding actuator, a manipulator for grabbing parts of ultrasonic motors, a frame, a visual detection and information sending device, a material transmission device, and a workpiece carrier. Disc, small terminal grabbing mechanism, the invention realizes the position and angle positioning of the ultrasonic electronic stator assembly in space by integrating several steps of machine vision, automatic assembly, feeding and welding, and combines it with machine learning, It can continuously learn through actual operation data to achieve better assembly effect and welding progress.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic motor manufacturing, in particular to a machine vision-based multi-point positioning assembly mechanism for an ultrasonic motor and a method thereof. Background technique [0002] At present, the holes on the PCB board of the ultrasonic motor are only 1 to 2 mm in size when assembled. In the current process, the ultrasonic motor stator PCB board and the terminals are basically matched by hand due to the small holes and relatively close positions. However, when the ultrasonic motor is mass-produced, the efficiency of manual assembly is too low, and it needs to consume a lot of manpower. Therefore, it is necessary to adopt the method of machine learning and robotic assembly to reduce the use of actual manual labor and improve the accuracy of assembly. SUMMARY OF THE INVENTION [0003] In order to solve the above problems, the present invention proposes a multi-point positioning assembly mecha...
