The second driving mechanism 31 drives the cleaning head 32 to contact the rear shell 100 in the vertical direction, so that the cleaning surface 320 abuts against the flat plate portion 101 and the bottom of the recessed portion 321 abuts against the surface of the boss portion 102.

[0045] In this embodiment, the working principle of the cleaning head 32 is as follows: the recessed portion 321 is arranged corresponding to the boss portion 102 of the rear shell 100, the recessed depth of the recessed portion 102 is equal to the height of the boss portion 102 protruding from the flat plate portion 101, when cleaning, the second driving mechanism 31 drives the cleaning head 32 to move in the vertical direction, when the cleaning head 32 contacts the boss portion 102, the boss portion 102 is accommodated in the recessed portion 321, when the first driving mechanism 22 drives the stage 23 to move, the bottom of the recessed portion 321 rubs against the surface of the boss portion 102, and the inner wall of the recessed portion 321 rubs against the peripheral wall of the boss portion 102, so as to clean. While cleaning the boss portion 102, the cleaning surface 320 of the cleaning head 32 also contacts the flat plate portion 101 of the rear shell 100, and while cleaning the boss portion 102, the cleaning surface 320 also rubs against a part of the flat plate portion 101, so as to clean the flat plate portion 101 at the same time.

[0046] In some embodiments, the recessed portion 321 may be a complete groove, the groove shape being set corresponding to the shape of the boss portion 102, or may be configured as a half groove. When configured as a half groove, two recessed portions 321 are usually provided, such as Figure 5 As shown. The two recessed portions 321 are respectively used to clean half of the side wall of the boss portion 102. Specifically, the cleaning head 32 is first driven by the second driving mechanism 31 to contact the rear shell 100, and the first recessed portion 321 is aligned with a part of the boss portion 102. The first driving mechanism 22 drives the stage 23 to move and start cleaning a part of the boss portion 102. After cleaning this part of the boss portion 102, the second driving mechanism 31 drives the cleaning head 32 away from the rear shell 100. The stage 23 can be moved or the cleaning head 32 can be driven to move by setting a separate driving device to align the other recessed portion 321 with the remaining uncleaned part of the boss portion 102. The second driving mechanism 31 drives the cleaning head 32 to contact the rear shell 100, so that the other recessed portion 321 contacts the uncleaned part of the boss portion 102, and the first driving mechanism 22 drives the stage 23 to move and continue cleaning.

[0047] Reference Figure 3 In some embodiments, the cleaning device 3 provided in the embodiment of the present invention further includes a first transmission mechanism 33, and the first transmission mechanism 33 includes a cam assembly 331 and a sliding assembly 332, wherein:

[0048] The cam assembly 331 includes a cam 3311 and a guide plate 3312. The cam 3311 is disposed at the output end of the first driving mechanism 22. The guide plate 3312 is disposed on the stage 23.

The two slide rails 3321 are arranged at intervals. Each slide rail 3321 is generally slidably connected with a slider 3322. The slider 3322 is connected to the worktable 23. When the first drive mechanism 22 outputs a torque and the cam 3311 rotates, the cam 3311 rotates to move the worktable 23. The setting direction of the slide rail 3321 provides guidance for the worktable 23, that is, when the cam 3311 rotates, the worktable 23 reciprocates horizontally along the setting direction of the guide rail 421, so that the recessed portion 321 can clean the boss portion 102 and its surrounding side.

[0051] In some embodiments, the first driving mechanism 22 may be a stepper motor or a servo motor, and those skilled in the art may select and design the motor according to actual needs.

[0052] In some embodiments, the cam assembly 331 can also be configured as follows: the limiting hole of the guide plate 3312 is configured as a waist-shaped groove, and the cam 3311 is configured as an ordinary circular roller. When the circular roller is driven to rotate, it contacts the inner wall of the waist-shaped groove and moves, and the horizontal reciprocating movement of the worktable 23 required for cleaning the rear shell 100 can also be achieved. Technical personnel in this field can select and design according to actual conditions.

[0053] In some embodiments, the sliding assembly 332 may also use a linear motion system of an optical axis and a linear bearing as a replacement, and the specific situation and corresponding design may be designed according to actual conditions.

[0054] Reference Figure 6 and Figure 7 In some embodiments, the cleaning device 3 proposed in the embodiment of the present invention also includes a mounting frame 34 arranged on the frame 1, and the second driving mechanism 31 includes a second driving motor 311 and a back pressure assembly 312 arranged on the mounting frame 34, one end of the back pressure assembly 312 is slidably connected to the mounting frame 34, and the other end is connected to the cleaning head 32, which is used to drive the cleaning head 32 to press the rear shell 100 on the stage 23.

[0055] In this embodiment, the second driving mechanism 31 also includes a screw nut 313, a screw 314, a screw seat 315 and a first mounting seat 316. The back pressure assembly 312 includes a second mounting seat 3120, a back pressure cylinder 3121, a back pressure valve 3122 and a balance spring 3123. The cleaning head 32 is installed on the first mounting seat 316. The output end of the second driving motor 311 is connected to the screw 314 through a coupling. The end of the screw 314 away from the second driving motor 311 is rotatably connected to the screw seat 315. The screw seat 315 is installed on the first mounting seat 316. The screw nut 313 is screwed to the screw 314 and installed on the second mounting seat 3120. A vertically arranged guide rail is provided on the mounting frame 34. The first mounting seat 316 and the second mounting seat 3120 are both equipped with sliders, and each slider is slidably connected to the guide rail. The fixed end of the back pressure cylinder 3121 is arranged on the second mounting seat 3120, and the output end of the back pressure cylinder 3121 is connected to the first mounting seat 316. There are two balancing springs 3123, one end of each balancing spring 3123 is connected to the first mounting seat 316, and the other end is connected to the second mounting seat 3120. The back pressure valve 3122 is arranged on the second mounting seat 3120 and connected to the back pressure cylinder 3121.

[0056] When cleaning is required, first the output end of the second drive motor 311 outputs torque, the screw rod 314 rotates, driving the screw nut 313 threaded therewith to move in the vertical direction, thereby driving the second mounting seat 3120 to move up and down, and the first mounting seat 316 connected by the back pressure cylinder 3121 moves synchronously with the movement of the second mounting seat 3120, so that the cleaning head 32 approaches the rear shell 100 on the lower stage 23 in the vertical direction until the cleaning head 32 contacts the rear shell 100, and the second drive motor 311 stops outputting, at which time the back pressure cylinder 3121 outputs driving force, causing the cleaning head 32 to move downward in the vertical direction, pressing the rear shell 100 below, and then the first drive mechanism 22 drives the stage 23 Movement for cleaning, the back-pressure cylinder 3121 applies force to the cleaning head 32 to make it press against the rear shell 100 with a certain pressure to ensure the cleaning force. The back-pressure valve 3122 is connected to the back-pressure cylinder 3121, and is used to adjust the output force of the back-pressure cylinder 3121, that is, the pressure that drives the cleaning head 32 to press against the rear shell 100. Under appropriate pressure, the rear shell 100 will not be broken due to excessive force, nor will the cleaning effect be poor due to too small force on the rear shell 100. The balancing tension spring 3123 is used to balance the output force of the back-pressure cylinder 3121 when it outputs, so that the output force process of the back-pressure cylinder 3121 is smooth, avoiding damage to the rear shell 100 that is pressed below due to excessive output force of the back-pressure cylinder 3121.

[0057] Reference Figure 3In some embodiments, the cleaning device 3 proposed in the embodiment of the present invention also includes a dust-free cloth mechanism 35 arranged on the mounting frame 34, the dust-free cloth mechanism 35 includes a dust-free cloth 351, a cloth supply assembly 352, a cloth collection assembly 353 and at least two tensioning wheels 354, the two tensioning wheels 354 are horizontally spaced and arranged between the stage 23 and the cleaning head 32, one end of the dust-free cloth 351 is wound around the cloth supply assembly 352, and the other end is sequentially wound around the two tensioning wheels 354 and then connected to the cloth collection assembly 353, the dust-free cloth 351 is used to wipe the rear shell 100 on the stage 23, the cloth supply assembly 352 is used to provide clean dust-free cloth 351, and the cloth collection assembly 353 is used to recycle the dust-free cloth 351 after use.

[0058] In this embodiment, the cloth supply assembly 352 is a first air-expanding shaft rotatably connected to the mounting frame 34, the clean dust-free cloth 351 is wound on the first air-expanding shaft, the cloth collection assembly 353 is composed of a second air-expanding shaft and a drive motor, the drive motor is arranged on the mounting frame 34, and its output end is connected to the second air-expanding shaft. The dust-free cloth extends out from the cloth supply assembly 352, passes through the two tensioning wheels 354 in turn, and is wound on the second air-expanding shaft of the cloth collection assembly 353. At this time, the dust-free cloth 351 is located in a section between the two tensioning wheels 354. Located between the cleaning head 32 and the stage 23, when cleaning is in progress, the second driving mechanism 31 drives the cleaning head 32 to move toward the stage 23, the cleaning head 32 first contacts the dust-free cloth 351, and then presses against the dust-free cloth 351, so that the dust-free cloth 351 contacts the rear shell 100 on the stage 23, and then the first driving mechanism 22 drives the stage 23 to move, so that the rear shell 100 on the stage 23 rubs against the dust-free cloth 351 pressed by the cleaning head 32, and the dust-free cloth 351 cleans the rear shell 100. After cleaning is completed, the second driving mechanism 31 drives the cleaning head 32 to move in the direction away from the loading platform 23, and then the driving motor of the cloth collecting assembly 353 is output to rotate the second air expansion shaft connected to the driving motor, and the dust-free cloth 351 is wound onto the cloth collecting assembly 353. At the same time, the clean dust-free cloth 351 wound on the cloth supply assembly 352 is driven to move between the two tensioning wheels 354. When the clean and unwiped dust-free cloth 351 moves between the cleaning head 32 and the loading platform 23, the cleaning operation of the next uncleaned rear shell 100 is continued.

[0059] The function of the dust-free cloth 351 is that when the cleaning head 32 is made of a slightly hard material, the cleaning head 32 is directly brought into contact with the rear shell 100, which may easily damage the rear shell 100. Using the dust-free cloth 351 as an intermediate contact material can play a certain buffering role, and the cleaning effect of the dust-free cloth is good. Most existing devices use the dust-free cloth 351 for cleaning.

[0060] In some embodiments, Figure 3As shown, the number of tensioning wheels 354 can be set as needed. The tensioning wheels 354 are used to tension the dust-free cloth 351 stored and received between the cloth supply assembly 352 and the cloth receiving assembly 353, and provide guidance for the movement of the dust-free cloth 351.

[0061] Reference Figure 3 , Figure 6 and Figure 8 In some embodiments, the cleaning device 3 proposed in the embodiment of the present invention also includes an alcohol spraying mechanism 36. There are two cleaning devices 3. The two cleaning devices 3 are horizontally spaced apart and arranged between the cloth supply assembly 352 and the cloth collection assembly 353. The alcohol spraying mechanism 36 is arranged between the two cleaning devices 3. The output end of the alcohol spraying mechanism 36 is arranged toward the dust-free cloth 351 between the two tensioning wheels 354, and is used to spray alcohol on the dust-free cloth 351.

[0062] In this embodiment, the fully automatic cleaning device for the back shell of the mobile phone of the present invention divides the cleaning of the back shell 100 into two types: dry cleaning and wet cleaning.

At this time, the alcohol spraying mechanism 36 first sprays alcohol onto the dust-free cloth 351 between the two tensioning wheels 354 to wet the dust-free cloth 351. Then the second driving mechanism 31 drives the cleaning head 32 to move in the direction toward the carrier 23, and the wet dust-free cloth 351 is abutted against the rear shell 100 on the carrier 23. Then the first driving mechanism 22 drives the carrier 23 to move for wet cleaning. After wet cleaning, the carrier device 2 is driven to move to the second cleaning device 3, and the second cleaning device 3 performs dry cleaning on it. The cleaning steps of dry cleaning of the second cleaning device 3 are different from those of wet cleaning in that there is no alcohol spraying mechanism 36 to spray alcohol, and the other steps are the same.

[0072] In this embodiment, the transfer device 5 is a linear motor, and the base 21 of the carrying device 2 is arranged on the mover of the linear motor. When the transfer device 5 outputs driving force, the carrying device 2 moves horizontally. When performing cleaning operations, the transfer device 5 first drives the loading platform 23 to receive the rear shell 100 to be cleaned at the loading position, and then drives the loading platform 23 to move to the first cleaning device 3 position for wet cleaning. After the wet cleaning is completed, the transfer device 5 drives the loading platform 23 to move to the second cleaning device 3 position for dry cleaning. After the dry cleaning is completed, the transfer device 5 drives the loading platform 23 to move to the bottom of the hole cleaning device 4 for hole cleaning. After the hole cleaning is completed, the transfer device 5 drives the loading platform 23 to the unloading position, waiting for manual or other handling devices to remove the cleaned rear shell 100, and then drives the loading platform 23 back to the loading position to continue loading, and repeats the loading, cleaning and unloading processes to realize automatic cleaning of the rear shell 100.

[0073] In some embodiments, the transfer device 5 can also be other driving devices such as a servo motor, a stepper motor, etc., and those skilled in the art can design it according to actual conditions.

[0074] Reference Figure 1 , Figure 3 Fig. 9 In some embodiments, there are four carrying devices 2 proposed in the embodiments of the present invention. The four carrying devices 2 are arranged at intervals along the material conveying direction. A temporary storage mechanism 6 is provided between every two adjacent carrying devices 2. The temporary storage mechanism 6 is located above the loading platform 23. Each temporary storage mechanism 6 is used to take and place the rear shell 100 on the two adjacent carrying devices 2.

[0075] In this embodiment, the transfer device 5 is provided with four movers, and four bearing devices 2 are respectively provided on one mover. The transfer device 5 can drive any mover independently, and the bearing devices 2 provided along the material conveying direction are respectively used for:

[0076] The first carrier device 2 receives the rear shell 100 at the loading position and is driven by the transfer device 5 to move to the first temporary storage mechanism 6. The first temporary storage mechanism 6 takes the rear shell 100 on the first carrier device 2, and then the first carrier device 2 is driven to return to the loading position to continue waiting for loading;

[0077] The second carrying device 2 is driven by the transfer device 5 to move to the first temporary storage mechanism 6, receives the rear shell 100 taken by the first temporary storage mechanism 6, and then is driven to move to the bottom of the first cleaning device 3 for wet cleaning. After the wet cleaning is completed, it is driven to move to the bottom of the second temporary storage mechanism 6. The second temporary storage mechanism 6 takes the rear shell 100 after wet cleaning, and then the second carrying device 2 is driven back to the first temporary storage mechanism 6 to continue receiving the rear shell 100.

[0078] The third carrying device 3 is driven by the transfer device 5 to move to the bottom of the second temporary storage mechanism 6, receives the wet-cleaned rear shell 100 from the second temporary storage mechanism 6, and then is driven to the bottom of the second cleaning device 3 to perform dry cleaning. After dry cleaning, it is driven to the third temporary storage mechanism 6. The third temporary storage mechanism 6 takes the rear shell 100 that has completed dry cleaning. Then, the third carrying device 2 is driven back to the bottom of the second temporary storage mechanism 6 to continue receiving the rear shell 100.

[0079] The fourth carrying device 2 is driven by the transfer device 5 to move to the bottom of the third temporary storage mechanism 6, receives the dried and cleaned rear shell 100 from the third temporary storage mechanism 6, and then continues to be driven to the bottom of the hole cleaning device 4 to clean the hole. After the hole cleaning, it is continued to be driven to the unloading position to wait for manual or other handling devices to unload the material. After the unloading is completed, it is continued to be driven back to the bottom of the third temporary storage mechanism 6 to continue receiving the rear shell 100.

[0080] Each carrying device 2 is driven individually by the transfer device 5, which saves transfer time during the automated cleaning process. If only a single carrying device 2 is provided, the single carrying device 2 must go through wet cleaning, dry cleaning, and hole cleaning in sequence from the loading position to the unloading position. After unloading, it returns to the loading position to receive the rear shell 100 for the next cleaning operation. The transportation time of the rear shell 100 is long, and the utilization rate of each device is low. Most of the time, it is in standby mode, which affects the efficiency of the cleaning operation. Setting multiple carrying devices 2 can segment the overall cleaning operation, saving the transportation time of the rear shell 100, thereby improving the efficiency of the equipment.

[0081] In some embodiments, the temporary storage mechanism 6 includes a driving cylinder disposed on the mounting seat 34 and a negative pressure suction head disposed on the output end of the driving cylinder. When the stage 23 is driven by the transfer device 5 and moved to the bottom of the temporary storage mechanism 6, the driving cylinder drives the negative pressure suction head to move in the direction toward the stage 23, so that the negative pressure suction head contacts the rear shell 100 on the stage 23, and the negative pressure suction head uses negative pressure to absorb the rear shell 100. Then, the driving cylinder drives the negative pressure suction head to move in the direction away from the stage 23 to pick up the rear shell 100 from the stage 23. While waiting for another stage 23 to come over to receive the rear shell 100, the driving cylinder cooperates with the negative pressure suction head to place the absorbed rear shell 100 on it.
