TECHNICAL FIELD
[0001] The present application relates to the technical field of automobile door handle detection, and particularly relates to a visual detection device for automobile door handle. BACKGROUND
[0002] Automobile parts are units that constitute the whole of automobile parts processing and products that serve automobile parts processing. Some automobile parts need to be electroplated after production, and the electroplated parts need to be visually detected by using a detection tool. The existing detection device uses a single light source to visually detect the parts. Since the inspected object lacks level changes of light, it is equivalent to visually judging the inspected object by relying on a single plane photo, and the accuracy is slightly poor. Therefore, the industry has made improvements.

By being provided with a white light LED lamp holder, a red light LED lamp holder and a blue light LED lamp holder, the detection of the door handle is changed from the original single white light detection to the detection of multiple light rays, so that the precision of the door handle detection is improved, and the ability to find defective products is greatly enhanced.
[0004] In actual use, the technology still has some shortcomings. When the visual detection device is detected, the worker only simply places the handle on the support plate.
