Description

Technical Field

[0001] This invention belongs to the field of wire harness processing technology, and more specifically, relates to a connection device and method for wire harness processing. Background Technology

[0002] Wire harnesses are widely used in electronic and electrical products, and their manufacturing quality directly affects product performance and safety. Traditional manual inspection of wire harnesses is inefficient and prone to errors, while existing automatic inspection systems suffer from problems such as low detection accuracy, poor environmental adaptability, and difficulty in detecting multiple defects simultaneously. The invention disclosed in application number CN202511067464.9 (publication number CN120620887A) is a laser marking system for wire harnesses based on CCD camera recognition. The system includes a robotic arm, wire harness grippers, wire harness end clamping units, a horizontal guide rail, a CCD vision detection unit, and a laser marking device. Two wire harness end clamping units are coaxially arranged on one side of each other, with two wire harness end insertion ports. The two wire harness grippers are mounted on a displacement robotic arm and can respectively clamp the target wire harness near both ends. Under the action of the robotic arm, the gripped target wire harness is moved between the two wire harness end clamping units, so that the two ends of the target wire harness are coaxially aligned with the wire harness end insertion ports of the two wire harness end clamping units. The two wire harness end clamping units can synchronously move along the extension direction of the horizontal guide rail. The original characters and patterns on the target wire harness are deflected from the line of sight of the CCD vision detection unit by the CCD vision detection unit, thereby effectively avoiding the original characters and patterns on the wire harness surface during the final marking process. The aforementioned patent can inspect wire harnesses, but it is not convenient to classify wire harnesses based on the test results. Since there are qualified and unqualified wire harnesses, it is necessary to distinguish them after the wire harness is tested. Summary of the Invention
