Problems solved by technology

However, it is difficult to solve the problem of visual occlusion when the assembly is close to each other. Most of them can only control the manipulator according to the previous image for tentative assembly.
This kind of assembly is time-consuming, low in efficiency, and difficult to guarantee accuracy

Embodiment Construction

[0021] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0022] Such as figure 1 As shown, a high-precision visual coaxial optical alignment assembly system for micro-sized structural parts includes a manipulator, a light source, an optical alignment device, a micro-motion platform, a camera device, and a control device; wherein the camera device and the optical alignment device are located at On the same horizontal line, the manipulator and the micro-motion platform are respectively located above and below the optical alignment device;

[0023] The manipulator includes a suction head for absorbing the accessories to be attached, which can automatically realize the adsorption and release of the accessories to be treated under the control of the control device, and there is no adhesion between the manipulator and the accessories to be attached.

[0024] The light source includes the light source of the base part and the lig...

Abstract

The invention provides a high-accuracy visual coaxial optical alignment assembly system for a miniature structural member. The system comprises a manipulator, a light source, an optical alignment device, a micro-positioning platform, an image pick-up device and a control device, wherein the image pick-up device and the optical alignment device are positioned on the same horizontal line; and the manipulator and the micro-positioning platform are positioned above and below the optical alignment device respectively. A local template is used, images of both a base member and a member to be arranged are binary images, and a binary edge only exists in the template matching process, so the calculated amount is greatly reduced and the speed is improved during matching, and the requirement on a positioning real-time property is met. The local template is used for searching an accurate alignment pixel coordinate and a directional line included angle of the base member and the member to be arranged, and the micro-positioning platform is adjusted under control of a control signal generated by the system, so that the system has higher alignment accuracy.

Description

technical field [0001] The invention relates to a high-precision visual coaxial optical alignment assembly system for miniature structural parts, which belongs to the field of mechanical assembly. Background technique [0002] With the development and rise of micro-mechanical technology and micro-electromechanical systems (MEMS), micro-miniature devices and systems are widely used in notebook computers, aerospace equipment, medical It is widely used in equipment and other products, involving various fields such as industry, aerospace, and medical treatment. Some micro-miniature devices are assembled through smaller structural parts. Therefore, the development and research of automatic and semi-automatic micro-structural part assembly systems has become an important research field. At present, most micro-assembly systems use a display device to display the assembly image, and the staff monitors the assembly image and uses the relative movement between the manipulators to com...
