Embodiment Construction

[0076] figure 1 An automatic assembly machine 100 is shown which has a frame 102 on which two parallel guides 103 are arranged. Two guides 103 support a transversely upstanding support arm 104 . The transversely arranged support arm 104 has a guide 105 on which a support part 106 is slidably mounted. The two guides 103 run in the y-direction and the guides 105 run in the x-direction. Arranged on the support part 106 is an assembly head 107 which has at least one component holding device designed as a pipette 120 which can be moved along a direction perpendicular to the x- direction and z-direction movement perpendicular to the y-direction.

[0077] In order to correct the angular position of the clamped element and thus to be able to assemble the element correctly, a rotary drive (not shown) is also provided. The pipette 120 can be rotated about its longitudinal axis by means of the rotary drive.

[0078] In addition, the automatic assembly machine 100 also has a componen...

Abstract

The present application describes a method for automatically identifying an electronic component (260a, 260b) using image processing. The method has the following steps: (a) loading a data record having different descriptions of the visual appearance of the electronic component (260a, 260b) into a data processing device (151), (b) loading a picture of the electronic component (260a, 260b) which has been taken by a camera (150) into the data processing device (151), and (c) comparing at least one feature of the different descriptions with at least one feature (265a, 265b) of the picture, with the component (260a, 260b) being identified as corresponding to the data record if the at least one feature (265a, 265b) of the picture corresponds to at least one feature of the data record within a prescribed tolerance.

Description

technical field [0001] The invention relates to a method for identifying electronic components by means of image processing, in which a model of a component to be identified is compared with one of the images of the component taken by a camera and the model corresponds to the electronic component shown on the image Component identification is considered correct. [0002] The invention also relates to an image processing system and an automatic assembly machine, both of which are designed to carry out the method according to the invention for recognizing components. [0003] Furthermore, the invention relates to a computer-readable storage medium and a program element, which contain instructions for carrying out the method according to the invention for identifying components. Background technique [0004] When the component carrier is automatically assembled by means of a so-called automatic assembly machine, the components are provided by the component supply device to the...
