An Accuracy Compensation System Applicable to Mounter

Abstract

The present invention provides an accuracy compensation system suitable for placement machines, including: a first camera, a second camera, a placement head, an image processing module and a control module, wherein the first camera is used to obtain the actual placement of the placement head The image information of the component; the second camera is used to obtain the image information of the standard mounted component preset on the PCB; the characteristic parameters of the actual mounted component are calculated according to the image information of the actual mounted component, and the actual mounted component is The characteristic parameters of the installed components are compared with the characteristic parameters of the standard mounted components to obtain the comparison results; according to the obtained comparison results, the air valve of the suction nozzle on the sticker is controlled to be closed and opened, so as to confirm whether the components are mounted. The present invention compares the information image of the actual mounted component with the standard mounted component, thereby judging whether the center coordinate and deflection angle of the actual mounted component absorbed meet the preset requirements to prompt the placement accuracy.

Description

technical field [0001] The invention relates to the technical field of placement machines, in particular to an accuracy compensation system suitable for placement machines. Background technique [0002] With the changes of the times and the continuous development of science and technology, in the production and manufacture of integrated circuits, the emergence of placement machines has greatly improved the efficiency of integrated circuit production and manufacturing. [0003] Today's placement machine mounts the electronic components on the PCB board through the single-chip microcomputer control program after the placement head picks up the electronic components to complete the placement work. However, there is a problem when the electronic components are mounted on the PCB board. Because the pick-and-place machine picks up the electronic components during the placement process, the angle of the electronic components will deflect when picking up, and it cannot be accurately...

Problems solved by technology

However, there is a problem when the electronic components are mounted on the PCB board. Because the pick-and-place machine picks up the electronic components during the placement process, the angle of the electronic components will deflect when picking up, and it cannot be accurately located in the center of the placement head. , resulting in inaccurate mounting accuracy
