Description

Technical Field

[0001] The utility model relates to the field of inspection robots, in particular to a robot for inspecting surface defects of plastic products. Background Art

[0002] The plastic product inspection robot is an automated device specifically designed to detect surface defects in plastic products. Through high-precision visual systems and algorithms, it can quickly and accurately detect surface defects on plastic products, such as cracks, burrs, and missing glue, thereby improving product quality and production efficiency.

[0003] Common inspection robots are usually composed of an integrated structure and can detect defects on the surface of workpieces. However, they lack quick-release structures and adjustment mechanisms, making it impossible to quickly install and remove measuring instruments, and the inspection angle of the measuring instrument cannot be freely adjusted. This not only affects the accuracy of the inspection robot, but also reduces work efficiency and practicality.

[0004] Therefore, in view of the fact that the above-mentioned inspection robot lacks a quick-release structure and an adjustment mechanism, and is unable to quickly install and disassemble the measuring instrument, and is unable to freely adjust the inspection angle of the measuring instrument, a plastic product surface defect inspection robot can be designed. By rotating the adjustment rod, the robot's rocker arm can be driven to rotate, and when the robot's rocker arm rotates, it will drive the optical image measuring instrument on its right end to move synchronously, and by starting the second motor, the rotating shaft and the movable plate can be driven to rotate synchronously, thereby adjusting the inspection angle of the optical image measuring instrument. When the optical image measuring instrument needs to be disassembled, the upper end of the second connecting member can be rotated to separate it from the mounting block, and at the same time, the second connecting member can be pulled to extend the telescopic pull rod, thereby increasing the distance between the second connecting member and the mounting block, so as to facilitate the separation of the first connecting member from the rear side of the mounting block, thereby quickly disassembling the optical image measuring instrument.
