Description

Technical Field

[0001] This utility model relates to the field of automotive trim technology, and in particular to a device for detecting surface defects in automotive trim. Background Technology

[0002] Automotive trim serves to decorate and beautify vehicles, and its quality directly impacts the car's interior and exterior image. Trim pieces should be selected strategically based on the car's specific needs, adhering to principles of aesthetics, harmony, practicality, and safety, to ensure the desired decorative effect.

[0003] Defect detection usually refers to the detection of surface defects of an item. Surface defect detection uses advanced machine vision inspection technology to detect defects such as spots, pits, scratches, color differences, and defects on the surface of a workpiece.

[0004] Currently, visual inspection technology is used to detect defects on the surface of ornaments. However, visual inspection is inconvenient for detecting the bottom of ornaments, as the ornaments need to be turned over, which makes the inspection process quite inconvenient. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems and shortcomings by proposing a device for detecting surface defects in automotive trim parts: A fixed motor is started to drive a bidirectional screw to rotate. The bidirectional screw, through a threaded block, drives the clamping plates on the connecting rod and support rod to move closer together. After the clamping plates move closer together, they clamp the two ends of the trim part through protective pads, facilitating the fixation of the trim part. Starting a rotating motor drives the clamping plates and the trim part to rotate, changing the detection surface of the trim part, facilitating adjustment, improving detection efficiency, and solving the problem of inconvenient flipping for detection.
