[0002] In the prior art, the detection head of a cutting machine includes a material suction device and a detection camera. After being cut, the product is conveyed to the feeding tray.

Moreover, the bottom plate can reflect light, and the reflected optical fiber reduces the detection accuracy of the detection camera.

[0034] To solve the above problems, as Figure 1 and Figure 2 shown, this embodiment provides a suction structure, which includes a bottom plate 1, a light-absorbing baffle 2 and a suction nozzle assembly 3; the light-absorbing baffle 2 is detachably connected to one side of the bottom plate 1, and the light-absorbing baffle 2 is used to reduce the reflection of interfering light to the detection end during product detection, and the detection end can be a detection camera; the light-absorbing baffle 2 is provided with an avoidance hole 21, the suction nozzle assembly 3 passes through the avoidance hole 21, and the suction nozzle assembly 3 is detachably connected to the bottom plate 1, and the suction nozzle assembly 3 is used to adsorb the product. During use, the suction nozzle assembly 3 adsorbs the product for the detection camera to detect the product on the suction nozzle assembly 3. During detection, the light-absorbing baffle 2 can absorb light, reduce the reflection of interfering light to the detection end during product detection, and improve the detection accuracy of the detection camera for the product. When the suction nozzle assembly 3 is damaged, there is no need to replace the entire suction structure. The suction nozzle assembly 3 can be disassembled, replaced or repaired through the bottom plate 1. Through the replaceable design, the maintenance cost of the suction structure is significantly reduced, the service life and stability of the suction structure are improved, and the possibility of misjudgment of the product size caused by the damage of the suction nozzle assembly 3 is reduced.

[0035] Preferably, the light-absorbing baffle 2 is black to prevent light reflection. Further preferably, the side of the light-absorbing baffle 2 away from the bottom plate 1 is a matte surface to further prevent light reflection.

During actual use, when the suction nozzle 32 is damaged due to reasons such as the stickiness or poor position of the product surface, only the suction nozzle 32 needs to be disassembled and replaced; if the support column 31 is damaged, the support column 31 can also be disassembled and replaced separately.

[0037] In this embodiment, the suction nozzle 32 is provided with a connection hole 22, and the second end of the support column 31 is in interference fit with the connection hole 22, realizing the detachable connection between the suction nozzle 32 and the support column 31.
