Automatic aligning assembly system for micro members

Abstract

The invention discloses an automatic aligning assembly system for micro members and belongs to the field of automatic control. The system has a function of assembling a part to be assembled on a basic part accurately and preventing the part to be assembled and the basic part from squeezing each other and being damaged. In the system, a control device is adopted, a motor servo system is adopted to control the rotation of a swing arm, an angle calibration device makes the rotation angle of the swing arm more accurate by testing the rotation angle, and a micro displacement worktable is adjusted to be able to rotate in six degrees of freedom by performing the corresponding calculation of images acquired by a microscope imaging system, so that the basic part and the part to be assembled can be matched accurately. In the invention, by regulating the operation of all parts through the control device, the assembly efficiency and precision are improved.

Description

technical field [0001] The invention relates to an automatic alignment assembly system for micro-sized structural parts, which belongs to the field of automatic control. Background technique [0002] Existing assembly systems for micro-sized structural parts generally have a vision system, most of which only play a monitoring role. The motion operation is realized by a combination of multiple manipulators and multiple degrees of freedom, and the random error is relatively large during the operation process. The operator controls the movement of the robot through the relative position of the assembly on the monitor to realize the tentative assembly operation. This assembly method results in large time consumption, low assembly efficiency, and poor consistency of assembly accuracy. In addition, for accurate alignment, the respective orientations of the two images must first be determined. The traditional method for determining orientations is through image template matching, ...

This assembly method results in a large time-consuming, low assembly efficiency, and poor consistency of assembly accuracy

In addition, for accurate alignment, the respective orientations of the two images must first be determined. The traditional method of determining the orientation is through the image template matching method, which has low accuracy and it is difficult to establish a standard template for absolute orientation determination.
