Abstract
An automatic pick-and-place system is provided, including a feeding device, a visual pattern formed on a fixed part of the feeding device, a manipulator, and a processing unit. An electronic component can be held between the fixed part and a gripping part of the feeding device. A visual module on the manipulator captures an image of the visual pattern, and the processing unit calculates the coordinate value of the electronic component. Thus, the manipulator can move to the target position and pick up the electronic element according to the coordinate value.

An automatic pick-and-place system, comprising:
- a feeding device, configured to move a tape and a plurality of electronic components disposed on the tape, wherein the feeding device has a base and a clamping unit disposed on the base, and the clamping unit includes a main body, a fixed part, and a gripping part, wherein the fixed part comprises a block mounted on the main body, the gripping part is movably disposed on the main body, and when the tape and one of the electronic components move to a predetermined position, the gripping part slides relative to the main body so that the electronic component is positioned between the gripping part and the fixed part;
- a visual pattern, formed on a surface of the block;
- a manipulator, having a visual module and a tooling module;
- and
- a processing unit, electrically connected to the visual module, wherein the visual module captures an image of the visual pattern on the fixed part and transmits the image to the processing unit, the processing unit calculates a coordinate value of the electronic component according to the image, the manipulator moves to a target position according to the coordinate value, and the tooling module then picks up the electronic component;
- wherein the visual pattern includes a first reference feature, a second reference feature, and a third reference feature, a first datum axis extends through the first reference feature and the second reference feature, and a second datum axis extends through the first reference feature and the third reference feature;
- wherein the first reference feature, the second reference feature, and the third reference feature are blind holes formed on a top surface of the fixed part.
