This invention discloses a method for detecting the adhesive color of Mini-LED beads, comprising the following steps: S1: Under fixed ambient light conditions, acquiring a first image of the Mini-LED bead to be tested after surface magnification before reflow treatment, and a second image of the Mini-LED bead to be tested after surface magnification after reflow treatment; S2: Restoring the Mini-LED bead to be tested from the first and second images; S3: Performing color analysis on the restored first and second images to obtain the first chromaticity value of the Mini-LED bead before reflow treatment and the second chromaticity value after reflow treatment; S4: Calculating the difference between the first and second chromaticity values ​​to determine whether the surface adhesive color of the Mini-LED bead is qualified based on the difference. This method for detecting the adhesive color of Mini-LED beads can automatically identify the surface adhesive color at the Mini-LED bead level and screen Mini-LED beads from the source, thereby improving the display effect of subsequent displays.

This utility model relates to an ultra-large diameter interchangeable roughing and finishing boring integrated device that can realize roughing and finishing of ultra-large diameter inner holes of different specifications. It includes a roughing and finishing boring body, a tool body connecting shank, a keyway box, a finishing boring tool box, a finishing boring cover, a roughing boring tool head, and a wooden guide key. These seven parts are assembled using screws, T-bolts, washers, and nuts. The wooden guide key is installed in the keyway box 1, and the roughing boring tool head's square groove is fitted with... Insert the rough boring tool, adjust the dimensions, and tighten the rough boring tool with screws. After adjusting the dimensions, install the finish boring tool into the tool slot of the finish boring tool box. Connect this device to the tool holder. The spindle rotates, and the tool holder drives the integrated rough and finish boring device to make linear motion, realizing one-time clamping and machining of the inner hole rough and finish boring. The keyway box, finish boring cover, and finish boring tool box can be replaced according to the hole diameter, so as to perform rough and finish boring of inner holes with different diameters.
