The setting of the adsorption plate 42 can effectively adsorb the dust onto the adsorption plate 42, preventing the dust from being lifted up again after falling to the bottom, helping to maintain a clean working environment. By driving the triangular star-shaped plate 37 to rotate through the rotating shaft 31, the triangular star-shaped plate 37 drives the moving plate 43 to move forward. The moving plate 43 drives the connecting rod 44 to slide back and forth in the through slot 45. The connecting rod 44 drives the connecting frame 46 to slide back and forth. The connecting frame 46 drives the arc-shaped scraper 47 to slide back and forth. The arc-shaped scraper 47 pushes the dust on the surface of the adsorption plate 42 away from the surface of the adsorption plate 42, preventing the holes of the adsorption plate 42 from being blocked by too much dust, and effectively reducing the potential impact of impurities on electronic components.
[0032] Turn on the electric push rod. The electric push rod drives the telescopic rod 51 to move downward. The telescopic rod 51 drives the die-cutting block 52 to move downward. After the pushing block 53 touches the mobile phone motherboard, the pushing block 53 will move upward. The setting of the pushing block 53 plays a role in impact buffering.
