Description

Technical Field

[0001] The utility model relates to the technical field of cutting mechanisms, in particular to a cam cutting mechanism. Background Art

[0002] At present, the AOI inspection equipment used to inspect LED lamp bead brackets needs to peel off and remove defective products on the inspected LED lamp bead brackets.

At the same time, there is no positioning mechanism for adjusting the position of the LED lamp bead bracket, nor is there a fixing mechanism for fixing the LED lamp bead bracket to prevent it from shifting during the cutting process. This will result in low cutting accuracy and stability during actual use, reduce cutting efficiency, and uneven cutting quality and effect.
