Referring to Fig. 1 to Fig. 5, in some embodiments, the present invention proposes a fully automatic cleaning device for the rear case of a mobile phone, which is used to clean the rear case 100 of an electronic product with a raised platform. The rear case 100 includes a flat part 101 and a raised The platform part 102 and the boss part 102 are provided with a plurality of through holes 103. It is characterized in that the fully automatic cleaning equipment for the rear case of the mobile phone includes:

Rack 1;

The carrying device 2 includes a base 21 located on the frame 1, a first drive mechanism 22 located on the base 21, and a stage 23 located at the output end of the first drive mechanism 22. The stage 23 is used to carry the rear shell 100 of the mobile phone ;

The cleaning device 3 is arranged on the frame 1 and is located above the object stage 23, and includes a second driving mechanism 31 and a cleaning head 32 arranged at the output end of the second driving mechanism 31. The second driving mechanism 31 is used to drive the cleaning head 32 to contact rear case 100;

The first driving mechanism 22 drives the stage 23 to move, so that the surface and peripheral side of the boss portion 102 are cleaned by the cleaning head 32 .

In this embodiment, the working principle of the fully automatic cleaning equipment for the rear case of the mobile phone of the present invention is as follows: firstly, the rear case 100 of the electronic product is placed on the stage 23 through manual loading or other feeding devices. The object table 23 is directly below the cleaning head 32, and the second driving mechanism 31 drives the cleaning head 32 to move vertically toward the rear case 100 on the object stage 23 until the cleaning head 32 touches the boss portion 102 on the rear case 100 , after contact, the first drive mechanism 22 drives the stage 23 to move, so that the surface of the boss portion 102 on the rear shell 100 and the peripheral side of the boss portion 102 rub against the cleaning head 32, and the cleaning head 32 is subjected to the rear shell 100. Cleans the rubbed parts and removes dirt. After the cleaning is completed, the second driving mechanism 31 drives the cleaning head 32 away from the rear case 100, and the cleaned rear case 100 is removed manually or by a feeding device, and then the process of loading, cleaning, and unloading is repeated to realize cleaning of the rear case 100. Automatic cleaning without manual cleaning, saving labor costs and high automation efficiency.

In some embodiments, the first driving mechanism 22 can also be set in the form of connecting the cleaning head 32. At this time, the stage 23 remains still, and the cleaning head 32 contacts the rear shell 100 on the stage 23, and is driven by the first The driving mechanism 22 moves to rub against the rear case 100 .
