[0025] Ventilation holes are evenly spaced on the surface of the side plate 21 , and a plurality of blades 22 are evenly spaced and connected to the left side of the side plate 21 at positions corresponding to the ventilation holes. The blades 22 are in an L-shaped structure.

[0026] A filter assembly 4 is installed at a position close to the side panel 21 on the inner wall of the inspection chamber of the chip appearance inspection equipment 1. The filter assembly 4 includes a filter plate 41. A limiting plate 42 is provided at the bottom end of the filter plate 41. The limiting plate 42 is embedded in the inner wall of the inspection chamber of the chip appearance inspection equipment 1 through a limiting groove. The top of the filter plate 41 is fixed inside the chip appearance inspection equipment 1 through a locking component 43.

[0027] The engaging component 43 includes an insert shaft 431 , which passes through the filter plate 41 through a through hole, and the end of the insert shaft 431 is inserted into the inner wall of the chip appearance inspection device 1 through a slot, and a pull ring 434 is connected to the bottom end of the insert shaft 431 .

[0028] A ring plate 432 is connected to the outer side of the top end of the insertion shaft 431 , and a support spring 433 is connected to the bottom end of the ring plate 432 . The bottom end of the support spring 433 is fixed to the top surface of the filter plate 41 through a groove.

The card plate 23 can be separated from the card slot of the chip appearance inspection device 1 during the movement. When the side plate 21 is rotated under force, the side plate 21 can open the opening of the chip appearance inspection device 1, which is convenient for directly touching the main devices inside the chip appearance inspection device 1, and then the inside of the chip appearance inspection device 1 can be inspected. At the same time, according to the attached Figure 5 As shown, the pull ring 434 is pulled down, and the pull ring 434 can drive the plug shaft 431 to move, and then the plug shaft 431 is separated from the slot of the chip appearance inspection device 1, and then the filter plate 41 can be removed, which is convenient for cleaning the filter plate 41.
