INSPECTION APPARATUS FOR WELDING TIP OF SPOT WELDING GUN AND ANALYSIS METHOD FOR POLLUTION AND ARRAY OF WELDING TIP USING THE SAME

摘要

The present invention discloses methods and apparatus for increasing inspection efficiency and reducing time for analyzing an image when inspecting contamination and alignment of the welding tip of the spot welding gun. An apparatus for inspecting a welding tip according to some embodiments of the present invention is configured to inspect the contamination and the alignment of the welding tip based on an end-surface image and a profile image of the welding tip. In particular, when recording the welding tip through an internal housing arranged in an internal space of an external housing, the noise generated from an external light source can be blocked, and hence the contamination and the alignment of the welding tip can be inspected by using a clearer image, thus improving the accuracy of the inspection.

主权项

1. An apparatus for inspecting a welding tip of a spot welding gun, the apparatus comprising:
an external housing including
an internal space therein, andan external inlet configured to allow each of a pair of welding tips facing each other to be inserted into the internal space; an internal housing arranged in the internal space of the external housing and including
a first internal inlet formed on a first side of opposing sides facing each other and configured to allow a first welding tip of the pair of welding tips inserted from the external inlet on one side to be inserted,a second internal inlet formed on a second side of the opposing sides and configured to allow a second welding tip of the pair of welding tips inserted from the external inlet on the other side to be inserted, anda first monitoring hole and a second monitoring hole respectively arranged close to the first internal inlet and the second internal inlet, a lighting unit configured to provide light to an inspection space defined by the internal housing; a camera unit arranged on the external housing and configured to record the pair of welding tips inserted into the inspection space and to acquire images of the pair of welding tips; and a control unit configured to receive the images of the pair of welding tips from the camera unit and to analyze a state of the welding tips by analyzing the images.
