Problems solved by technology

[0004] Existing vision-based dispensing machines only control the three-dimensional positioning platform according to the two-dimensional visual information of the XY axis, and the Z-axis information is often given artificially. There is no corresponding solution for the acquisition of height information in the Z-axis direction
In addition, the calibration of the internal and external parameters of the visual camera is usually carried out using calibration blocks. The results of such calibration often depend on the accuracy of human calibration, so the positioning effect of the system is often poor, and the movement of the mechanical platform appears to be jittery and the overall deviation of the positioning position. shift

Abstract

The invention relates to a three-dimensional positioning device based on visual guidance and dispensing equipment. The three-dimensional positioning device comprises an X axis motion system; a Y axis motion system, wherein the X axis motion system is movably supported on the Y axis motion system, and the Y axis motion system drives the X axis motion system to move along the axial direction of the Y axis motion system; a Z axis motion system, wherein the Z axis motion system is installed on the Y axis motion system, the X axis motion system drives the Z axis motion system to move along the axial direction of the X axis motion system; an image obtaining unit installed above the Z axis motion system and used for obtaining the height position information of a target position and plane center position information of the target position; and a controller electrically connected with the X axis motion system, the Y axis motion system, the Z axis motion system and the image obtaining unit and used for driving the X axis motion system, the Y axis motion system and the Z axis motion system to move according to the height position information and the plane center position information. The three-dimensional positioning device provided by the invention improves the positioning effect of the system.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a three-dimensional positioning device and dispensing equipment based on vision guidance. Background technique [0002] At present, the known three-dimensional dispensing platform structure is composed of an X-axis motion system, a Y-axis motion system, a Z-axis motion system, and a dispensing valve. The three-dimensional coordinates of the fixed position are given, and the manipulator performs repeated positioning of the circuit board chip position, and then Control the dispensing valve for dispensing. [0003] However, due to the diversity and flexibility of operating circuit boards, the applicability of the three-dimensional dispensing positioning platform with fixed XYZ coordinates is very poor, and the mechanical screw will be worn after repeated positioning, resulting in poor positioning accuracy. to preset indicators. At present, most dispensing machine systems have poor repeatabi...
