[0026] Embodiment 1
[0027] A metal surface defect detection device is provided, wherein a detection component 10 is installed on a door frame 60 .
[0028] The detection component 10 is used to detect defects on the surface of metal parts. The detection component 10 includes a cover 11 and an ultrasonic flaw detector 12 arranged on the lower side of the door frame 60, and the cover 11 is covered on the outside of the ultrasonic flaw detector 12.
[0029] The cover 11 protects the ultrasonic flaw detector 12. When detecting defects, the ultrasonic signal emitted and received by the ultrasonic flaw detector 12 is processed into a waveform image. The shape of the waveform can be used to identify minor defects such as scratches, local bumps, etc. on the surface of the metal part.
[0030] The frame 20 is located below the detection assembly 10 . A first roller 21 and a second roller 22 are disposed on the frame 20 . Two annular grooves 23 are formed on the first roller 21 and the second roller 22 .
[0031] The frame 20 is fixed to the door frame 60 , and the first roller body 21 and the second roller body 22 are rotatably connected to the frame 20 .
[0032] The carrying assembly 30 includes a power source 31 and two belts 32. The power source 31 is installed on the frame 20 and is transmission-connected to the first roller 21. The two belts 32 are sleeved on the first roller 21 and the second roller 22. The two belts 32 are respectively embedded in the two annular grooves 23 and are distributed in parallel.
[0033] One end of the two belt bodies 32 is a loading station, and the other end is a discharging station. The power source 31 is preferably a servo motor. The output end of the power source 31 is connected to a main gear ring 311, and the first roller body 21 is connected to a slave gear ring 312. The main gear ring 311 is meshed with the slave gear ring 312. Multiple metal parts are placed on the two belt bodies 32 at intervals. The first roller body 21 is driven to rotate at intervals by the power source 31, so that the two belt bodies 32 can operate to transport multiple metal parts.
[0034] The push plate 40 is connected to the frame body 20 through a telescopic source 41. A fixing component 50 is arranged on the push plate 40. The push plate 40 can push the metal parts on the two strip bodies 32 to move upward and approach the detection component 10.
[0035] The telescopic source 41 is installed on the frame body 20. The push plate 40 is connected to the movable rod of the telescopic source 41. The push plate 40 is located between the two strip bodies 32. The telescopic source 41 is preferably an electric cylinder body. After the metal part runs above the push plate 40 and stays, the movable rod of the telescopic source 41 extends, so that the push plate 40 ejects the metal part from the two strip bodies 32, and makes the metal part move upward and maintain a certain distance for defect detection. After the detection is completed, the metal part is reset and placed on the two strip bodies 32, and is conveyed away with the operation of the two strip bodies 32. Thus, the remaining metal parts can be detected in turn without long-distance handling, effectively improving the detection efficiency.
[0036] Embodiment Two
[0037] A metal surface defect detection device is provided. A plurality of idler rollers 201 for supporting the strip body 32 are arranged on the frame body 20.
[0038] The idler rollers 201 support the strip body 32 to prevent the strip body 32 from sagging downward and causing the metal parts to overturn, realizing the stable conveying of the metal parts. And the idler rollers 201 do not extend between the two strip bodies 32 and will not contact the metal parts.
[0039] A plurality of lifting plates 221 are arranged on the second roller body 22. The plurality of lifting plates 221 are all rubber plates.
[0040] After the metal parts are detected, the lifting plates 221 can lift the metal parts upward, which is convenient for taking.

[0042] The suction source 52 is preferably a vacuum pump. After the push plate 40 contacts the metal part, a negative pressure is generated at the suction holes 51 by the suction of the suction source 52. Thus, the position of the metal part on the push plate 40 is fixed, and it is not easy to damage the metal part.
