[0021] (2) The invention drives the copper tube body to rotate by rotating the turntable. The inner and outer walls can be inspected in all directions by rotating the copper tube body, thereby improving the inspection efficiency and preventing some positions from not being detected, which may cause safety hazards. At the same time, the movement of the sliding plate toward the copper tube body drives the brush plate toward the copper tube body. The brush plate contacts the copper tube body, so that impurities attached to the copper tube body can be cleaned off during the rotation of the copper tube body. This prevents the impurities from causing image blur during image inspection, reducing the image clarity and affecting subsequent image processing and analysis.

[0022] (3) The invention uses a cleaning rod to clean impurities attached to the brush plate, preventing the impurities from being attached to the brush, causing the brush plate to be attached to the copper tube body again when it is cleaned next time, affecting the detection effect.

6. The copper tube surface defect image detection device according to claim 5, characterized in that: The anti-adhesion device comprises a trapezoidal slide plate (181), a connecting plate (182), a cleaning rod (183) and a fixing rod (184); the trapezoidal slide plate (181) is slidably mounted on the bottom of the sliding plate (176); a groove is provided on the top of the trapezoidal slide plate (181); the connecting plate (182) is fixedly mounted on the top of the trapezoidal slide plate (181); the cleaning rod (183) is fixedly mounted on the top of the connecting plate (182); and the fixing rod (184) is fixedly mounted on the top of the base (1).

7. The copper tube surface defect image detection device according to claim 6, characterized in that: A connecting frame (185) is fixedly mounted on the surface of the brush plate (178), a rotating block (186) is rotatably mounted on the inner wall of the connecting frame (185), and a limiting block (187) is fixedly mounted on the inner wall of the connecting frame (185).

8. The copper tube surface defect image detection device according to claim 7, characterized in that: A No. 6 spring is arranged between the trapezoidal slide plate (181) and the sliding plate (176), a No. 2 torsion spring is arranged between the connecting frame (185) and the rotating block (186), and the limiting block (187) is in surface contact with the rotating block (186).

9. A method for detecting copper tube surface defects using an image detection device, using the copper tube surface defects image detection device according to claim 8, characterized in that: The following steps are involved: Step 1: Place the copper tube body (7) on the top of the turntable (6), start the electric telescopic rod (3) to move downward, the electric telescopic rod (3) moves downward to drive the image detector (4) to move downward, and the image detector (4) moves downward to detect the inner and outer walls of the copper tube body (7) to prevent internal defects that may cause problems in subsequent use; Step 2: The inner wall of the copper tube body (7) is supported by the arc plate (12), and the support can provide a stable detection platform to reduce the detection error caused by external force or equipment vibration; Step 3: The L-shaped rod (11) moves toward the inner wall of the copper tube body (7) to drive the fixing plate (13) to move toward the inner wall of the copper tube body (7); the fixing plate (13) moves toward the inner wall of the copper tube body (7) to drive the L-shaped plate (14) to move toward the support seat (15); Step 4: Move the L-shaped plate (14) toward the support seat (15) to push one end of the rotating plate (16) to rotate upward. The upward rotation of one end of the rotating plate (16) drives the other end to rotate downward. The outer wall of the copper tube body (7) is supported by the rotation of the rotating plate (16). The supported outer wall can ensure that the copper tube maintains a stable posture during the detection process, avoiding the difficulty of defect detection caused by tilting or movement.
