The light shielding panel is connected with a rotary connecting assembly. The light shielding panel is rotatably connected to the connecting piece through the rotary connecting assembly. The mounting body is installed below the connecting piece.

[0006] The outer side of the connecting piece is connected with an outer connecting ring below. A limiting ring groove is formed in the outer connecting ring. The mounting body is sleeved on the outer connecting ring and connected with the connecting piece through locking bolts. The locking bolts are threadedly connected with the mounting body, and the bottom end of the locking bolts penetrates through the mounting body and abuts against the bottom wall of the limiting ring groove.

[0007] The outer side of the connecting piece is also connected with an upper limiting ring. The rotary connecting assembly comprises a frame connected with the light shielding panel. The frame is connected with a first semicircle ring. The rotary connecting assembly further comprises a second semicircle ring matched with the first semicircle ring. The second semicircle ring is connected with the first semicircle ring through bolts, and forms a circular ring with the first semicircle ring. The circular ring is rotatably connected to the connecting piece and limited between the upper limiting ring and the mounting body.

[0008] The light shielding panel is coated with a light absorbing coating layer near the ultraviolet lamp belt side.

[0009] The light shielding panel is arc-shaped.

[0010] The utility model discloses a LED wafer inspection device can reach technical effect is: the utility model discloses a kind of LED wafer inspection device, including installation main body, connecting piece and the light shield panel for shielding ultraviolet light, the problem of ultraviolet light reflection damage human body is solved by light shield panel, and light shield panel is rotatably connected on connecting piece by rotating connection component, thus the position of light shield panel can be changed according to requirement;The light source of the utility model is annular ultraviolet lamp strip, so that the entire wafer is evenly excited, and the inspection error is improved.
