An alcohol spraying mechanism 2 is provided on the front side of the first brush 7 of the second set of brushes for spraying alcohol onto the middle surface of the phone back cover 00. First, the alcohol spraying mechanism is activated to spray alcohol onto the middle surface of the phone back cover. The phone back cover is then conveyed to the area below the second clamping belt along the conveyor belt. The second clamping belt runs in the opposite direction with the conveyor belt. The two ends of the phone back cover are clamped by the second clamping belts on both sides and the conveyor belt. At the same time, the cleaning motor in the middle is activated, allowing the rotating brushes to clean the exposed surface of the middle part of the phone back cover.

[0032] To further optimize the above solution, auxiliary pressing blocks 10 for pressing the back cover 00 of the mobile phone are provided between the upper and lower belts of the first pressing belt 4 and the second pressing belt 9. The two sides of the auxiliary pressing blocks 10 are connected to the body 1 through support rods 11. With the help of the auxiliary pressing blocks, the back cover of the mobile phone can be further pressed to ensure that it will not shift during the brush cleaning process.

[0033] In specific assembly, the brush 7 is cylindrical, and the top of the connecting end of the brush 7 is coaxially fixed with the output shaft of the cleaning motor 8. The cleaning motor 8 is connected to the machine body 1 through a gantry frame (not shown in the figure).

[0034] In specific embodiments of this utility model, such as Figure 1 , 2 As shown, a positioning plate 21 is provided on the side of the feed end of the conveyor belt 3 for positioning the back cover of the mobile phone on the conveyor belt 3; the positioning plate 21 is set on the top of the machine body 1, and its positioning end extends above the conveyor belt 3. The mobile phone back cover is placed onto the conveyor belt manually with the help of the positioning plate, ensuring consistent placement and maintaining the consistent position of the mobile phone back cover relative to the conveyor belt and the brush above during transportation and cleaning, further ensuring the cleaning effect. Alternatively, it can be used in conjunction with a feeding machine, which transports the mobile phone back covers one by one onto the conveyor belt, and then manually adjusts their positions by contacting one end with the positioning plate.

[0035] In the specific production process, such as Figure 2 As shown, the conveyor belt 3 is driven by a conveyor motor, and the rollers at both ends are connected to the machine body 1 via connecting frames 12. The side of the machine body 1 is equipped with a speed control knob 13 and a switch 14 for controlling the conveyor belt 3. The conveyor motor, alcohol spraying mechanism 2, and cleaning motor 8 are all connected to a controller (not shown in the figure), which is located inside the machine body 1. The speed control knob and switch control the running speed and start / stop of the conveyor belt, while the controller controls the actions of each component, enabling automatic conveying of the mobile phone back cover, automatic alcohol spraying by the alcohol spraying mechanism, and automatic cleaning by the brush, thus improving the automation level of the equipment. The conveyor belt and controller are conventional technologies in this field, and their structures will not be described in detail here.

[0036] In a specific embodiment of this utility model, protective plates 15 are installed on both sides of the machine body 1 to protect the conveyor motor and controller inside the machine body. Simultaneously, four casters 16 and 14 are installed at the bottom of the machine body, respectively located at the four corners of the bottom, and each caster 14 is equipped with a brake. The casters facilitate moving the equipment to any work location, improving the equipment's flexibility.

[0037] In specific design, such as Figure 1 , 2 As shown, the alcohol spraying mechanism 2 is an electric pneumatic spray bottle. The bottle body of the electric pneumatic spray bottle is located on the top of the machine body 1, and the nozzle at the end of the spray pipe faces the surface of the phone's back cover. The electric pneumatic spray bottle in this embodiment is existing technology; appropriate specifications can be purchased externally according to production needs. The spray volume is adjusted using the air valve on the electric pneumatic spray bottle to spray alcohol onto the surface of the phone's back cover and the character area.

[0038] In specific embodiments of this utility model, such as Figure 1 , 2 As shown, the flipping unit 200 includes a rotating drum 17 and a flipping motor 18. The output shaft of the flipping motor 18 is coaxially fixed with the rotating drum 17. Multiple buckets 19 are radially evenly distributed on the outer circumference of the main shaft of the rotating drum 17. Baffles 20 are provided at both ends of the rotating drum 17, and the two ends of the buckets 19 are respectively connected to the inner walls of the baffles 20 on both sides. In specific manufacturing, the ends of the buckets can be slightly tilted upwards to ensure that the back cover of the mobile phone will not slide out inside the bucket. The flipping motor has a built-in reducer to drive the buckets to rotate at a low speed. When the bucket on the left rotates upwards in the figure, it can catch the back cover of the mobile phone that slides off the conveyor belt of the front cleaning station on the left. Then, the bucket carries the back cover of the mobile phone to the right side of the reverse cleaning station. When the bucket rotates downwards, the back cover of the mobile phone can slide onto the conveyor belt of the reverse cleaning unit.

[0039] Further optimize the above solution, such as Figure 3 As shown, the upper conveyor belt 3 of the first cleaning component is higher than the upper conveyor belt 3 of the second cleaning component. The conveyor belt 3 of the first cleaning component is positioned diagonally above the rotating drum 17, and the conveyor belt 3 of the second cleaning component is positioned diagonally below the rotating drum 17. This structure allows the left-side phone back cover to slide smoothly into the bucket that rotates to the left side. After the bucket rotates to the right side, the phone back cover can slide smoothly onto the right-side conveyor belt.

[0040] In summary, this utility model has the advantages of compact structure, high work efficiency, and good cleaning quality. After the phone back cover is positioned by the positioning block, it moves to the front cleaning station by the conveyor belt. The electric pneumatic sprayers on both sides spray alcohol onto the surfaces at both ends and the character area of ​​the phone back cover. Then, it moves to below the first pressing belt, where the brushes on both sides are activated for cleaning. Subsequently, the electric pneumatic sprayers spray alcohol onto the middle surface of the phone back cover, which then moves to below the second pressing belt, where the brushes in the middle are activated for cleaning. After the front cleaning, the phone back cover falls into the bucket by the conveyor belt. The rotating bucket flips it over and places it onto the conveyor belt at the reverse cleaning station, repeating the front cleaning process to complete the reverse cleaning of the phone back cover. This utility model utilizes universal casters, allowing the equipment to be moved at any time by plugging in electricity or air, making it convenient and flexible. The positioning block device ensures the consistent position of the phone back cover. Alcohol is automatically sprayed before cleaning, and the upper and lower belts rotate and press the phone back cover, ensuring that the product does not shift during operation. This realizes an automated cleaning line for phone back cover cases. This invention liberates labor, improves cleaning efficiency, and ensures the cleaning quality of the phone's back cover.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
