[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0026] The utility model discloses a device for continuously cleaning dust and foreign matter on a carrier plate and reducing dust on the surface of a blue diaphragm. Figure 1-3 As shown, it includes a brush cleaning unit 3 arranged on the carrier conveyor frame 1, and also includes a lifting unit 4 and a dust collection unit 5 on the carrier conveyor frame 1;

[0027] The brush cleaning unit 3 is used to clean the carrier plate body 6 on the conveyor belt 2.

[0028] The lifting unit 4 is used to control the lifting of the brush cleaning unit 3, thereby adjusting the contact area and friction between the brush body 301 and the carrier body 6, thereby ensuring that the brush cleaning unit 3 has a good cleaning effect on the carrier body 6.

[0029] The dust collection unit 5 is used to absorb and remove dust and foreign matter cleaned by the brush body 301 .

[0030] The brush cleaning unit 3 includes a brush body 301 arranged on the conveyor belt 2, a support arm 302 and a motor 303 arranged on the carrier conveyor frame 1. The brush body 301 is arranged at the lower return entrance of the PVD host, and the motor 303 is arranged on the support arm 302 and is connected to the rotating shaft of the brush cleaning unit 3; a pulley 304 is provided on the rotating shaft of the brush body 301, and a belt 305 is provided on the pulley 304 and the transmission wheel at the output end of the motor 303;

[0031] The rotation of the brush body 301 in the brush cleaning unit 3 is driven by the motor 303. The output end of the motor 303 drives the belt 305 to rotate, the belt 305 drives the pulley 304 to rotate, and the pulley 304 drives the brush body 301 to rotate along the support arm 302. When the brush body 301 contacts the surface of the carrier body 6 and rotates, the surface of the carrier body 6 is cleaned.

[0032] The lifting unit 4 includes an electric push rod 401 fixedly connected to the carrier conveyor frame 1, and the output end of the electric push rod 401 is connected to the support arm 302;

[0033] When the brush cleaning unit 3 needs to be controlled to rise and fall, it is driven by the electric push rod 401, which drives the support arm 302 to move, and the support arm 302 drives the motor 303 and the brush body 301 to move, thereby controlling the lifting action of the brush cleaning unit 3;

[0034] The bottom of the support arm 302 is fixedly connected to a support rod 403, and the plate conveyor frame 1 is connected to a support tube 402. The support rod 403 is slidably connected to the support tube 402. When controlling the lifting and lowering of the brush cleaning unit 3, the support arm 302 drives the support rod 403 to slide along the inside of the support tube 402, so that the support arm 302 is supported, ensuring the good lifting and lowering stability of the brush cleaning unit 3.

[0035] The dust collection unit 5 includes a closed cover 501 arranged on the support arm 302 and a dust collection fan connecting pipe 502 arranged on the closed cover 501. The dust collection fan connecting pipe 502 is connected to the dust collection fan. When the dust collection fan is operating, suction is generated to absorb the dust inside the closed cover 501, thereby ensuring that the device has a good cleaning effect on the carrier body 6.

[0036] A metal strip 5011 is provided on the closed cover 501, and a dust-proof brush 5012 is provided on the metal strip 5011. The metal strip 5011 and the dust-proof brush 5012 make it convenient for the carrier body 6 to enter the interior of the closed cover 501 and be isolated from the external environment when the conveyor belt 2 transports the carrier body 6.

[0037] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
