[0034] The working principle of the circuit board detection device in this embodiment is: a manual or automatic device places the circuit board on the table 2, then retrieves the pre-stored data to perform two-point positioning of the circuit board, and then controls the three-dimensional moving device to drive the optical lens module 3 to move to perform line detection and hole wall detection on the circuit board, and outputs optical detection data at the same time, and finally automatically or manually determines whether the circuit board is qualified.

[0035] Compared with the prior art, the circuit board detection device in this embodiment is designed with a three-dimensional mobile device on the frame 1 and then sets a hole wall detection component 31 and a line detection component 32 on the three-dimensional mobile device, and the hole wall detection component 31 and the line detection component 32 are structurally defined respectively.
