[0032] The fixing mechanism also includes an air pump 305 fixedly connected to the inner bottom wall of the supporting frame 301. The air pump 305 is connected to the suction cup 302 through a pipeline. By fitting the back of the mobile phone with the top of the suction cup 302, and then pressing the mobile phone downward until the mobile phone fits with the top of the supporting frame 301, the suction cup 302 will fit tightly with the back of the mobile phone under the action of the connecting spring 303. Then, by starting the air pump 305, air is pumped into the interior of the suction cup 302, so that the interior of the suction cup 302 presents a negative pressure, thereby fixing the mobile phone. There are several fixing mechanisms, which are linearly and evenly distributed on the outer surface of the conveyor belt 1.

[0033] By fitting the back of the mobile phone with the top of the suction cup 302, and then pressing the mobile phone downward until the mobile phone fits with the top of the carrier frame 301, the suction cup 302 will fit tightly with the back of the mobile phone under the action of the connecting spring 303, and then starting the air pump 305 to evacuate the inside of the suction cup 302, so that the inside of the suction cup 302 presents a negative pressure, thereby fixing the mobile phone, and then conveying the mobile phone to the bottom of the cleaning mechanism through the conveyor belt 1.

[0034] Embodiment 2: Figure 1-5 As shown, a dust removal device for a mobile phone LCD screen includes a conveyor belt 1 and a bracket 2 fixedly connected to the top of the conveyor belt 1, a fixing mechanism arranged on the top of the conveyor belt 1, and a cleaning mechanism fixedly connected to the bottom of the bracket 2;

[0035] The fixing mechanism includes a carrying frame 301 fixedly connected to the top of the conveyor belt 1, and a suction cup 302 movably arranged on the top of the carrying frame 301 for adsorbing the mobile phone;

[0036] The cleaning mechanism includes a transmission block 404 movably disposed at the bottom of the bracket 2, and a cleaning sponge 405 connected to the transmission block 404 via a connecting piece for cleaning the display screen.

[0037] The cleaning mechanism also includes an electric push rod 401 fixedly connected to the bottom of the bracket 2, a mounting frame 402 fixedly connected to the output end of the electric push rod 401, and a flip motor 403 fixedly connected to the inner side wall of the mounting frame 402;
