[0002] In the field of automatic production and testing of lighting strips, it has become a common practice in the industry to complete the final inspection before the product is put into operation by combining special fixtures with detection equipment. In the prior art, the testing of lighting strips is usually completed in series on multiple independent stations in a linear layout, such as loading, power-on, optical performance detection, connector PIN detection, and final sorting in open or semi-enclosed stations. Some improved schemes attempt to install a local light shield in the optical detection link and introduce a mechanical arm to perform product transfer between stations in order to improve the degree of automation of the operation.

[0003] However, such prior art solutions have a series of inherent defects that are interrelated: first, the serial operation process limits the overall test cycle to the time consumed by the slowest process, resulting in low comprehensive utilization of equipment and restricting further improvement of production efficiency; second, the semi-enclosed structure of the optical detection station cannot completely isolate environmental light interference, and subtle changes in external light can easily cause the consistency of CCD camera image acquisition to decrease, affecting detection accuracy and reliability; third, existing equipment lacks the ability to perform integrated, high-precision terminal testing of lighting strips, making it difficult to simultaneously complete reliable evaluation of their electrical performance (such as circuit conduction and electrical parameters) and optical performance in a closed environment, and the testing of different models of lighting strips, especially the detection of connector PINs, often requires downtime and manual replacement of corresponding clamping fixtures, which not only increases operational complexity and labor costs, but also disrupts the continuity of production, making it difficult to meet the needs of flexible production; in addition, the functional modules in existing solutions are usually independent units, lacking system-level integration and collaborative control, and there is still a gap in the full-process integrated solution from testing to automatic sorting of qualified and unqualified products, making the entire testing process still have many manual intervention links.
