The workpiece is placed on the feeding member 14, and through the actions of the first moving component 11, the second moving component 12, and the rotating component 13, the workpiece cooperates with the cleaning structure 103 on the feeding member 14 to enable cleaning. It can be understood that the first direction can be the direction of moving left and right along the long axis direction of the frame 101. The second direction can be the direction of moving back and forth along the short axis direction of the frame 101. The rotating component 13 can drive the feeding member 14 and the workpiece located on the feeding member 14 to rotate to clean different parts of the workpiece. Among them, a vacuum suction member can be provided on the feeding member 14 to better adsorb the workpiece, so that the workpiece can be placed more stably on the feeding member 14. In some embodiments, the workpiece can be quadrilateral, and the rotating component 13 rotates 90° each time to clean different areas of the workpiece. The rotation angle of the rotating component 13 each time can be set according to the specific shape of the workpiece and the area to be cleaned, that is, the rotation angle of the rotating component 13 can also be 30°, 45°, 60°, etc., and the present application does not make specific limitations thereto. Exemplarily, the workpiece can be a mobile phone panel. The mobile phone frame and the screen are bonded by hot melt adhesive, which can play a role in waterproofing. However, during the bonding process, the glue will stick to the screen or the frame, and the cleaning device 100 of the present invention can be used for cleaning.

The material receiving mechanism 30 includes a second material rack 31 and a second driving component 32 connected to the second material rack 31. The cleaning belt is wound around the first material rack 21. The first driving component 23 and the second driving component 32 act to enable the cleaning belt to pass through the cleaning mechanism 50 and be received on the second material rack 31. Among them, the material receiving mechanism 30 further includes a pulling component 33 and an outer cover 34. The pulling component 33 is used to pull and feed the cleaning belt. An accommodating cavity for accommodating the second material rack 31 and the pulling component 33 is formed inside the outer cover 34. A first sensing component 35 for monitoring the gas concentration of the volatile cleaning liquid in the accommodating cavity is further provided in the accommodating cavity. It can be understood that the cleaning liquid can be alcohol. Since alcohol is highly volatile, flammable and explosive, there are certain safety hazards. Therefore, the cleaning cloth that has wiped the workpiece and has alcohol is received on the second material rack 31, and the second material rack 31 is arranged in a closed accommodating cavity to prevent the volatile alcohol gas from volatilizing into the air and causing danger. A first sensing component 35 for monitoring the alcohol concentration is provided in the accommodating cavity. When it is monitored that the alcohol concentration is greater than a certain range, the gas in the accommodating cavity can be pumped away or removed by other means. An opening for pumping air can be provided on the accommodating cavity.

[0051] Please refer to Figure 7 , in some alternative embodiments, the pulling component 33 includes a movable wheel 331, a traction wheel 332, a lifting cylinder 333 and a traction motor 334. Specifically, the number of the movable wheels 331 is two and they are arranged side by side to better cooperate with the traction wheel 332. The two movable wheels 331 are arranged opposite to the traction wheel 332, and the cleaning cloth passes through between the movable wheel 331 and the traction wheel 332. The movable wheel 331 is connected to the lifting cylinder 333. The lifting cylinder 333 acts to lift the movable wheel 331 away from the traction wheel 332 to facilitate the passing of the cleaning cloth. Or the lifting cylinder 333 acts to drive the movable wheel 331 closer to the traction wheel 332 to better pull the cleaning cloth. A plurality of grooves are evenly distributed on the traction wheel 332 to better pull the cleaning cloth. The traction wheel 332 is connected to the traction motor 334.

[0052] Please refer to Figure 8, in some alternative embodiments, the liquid spraying mechanism 40 includes a liquid storage member 41, a metering pump 42, and a liquid spraying assembly 44.

In this embodiment, the cleaning belt can be a dust-free cloth, and the cleaning liquid can be a liquid such as alcohol, thinners, degumming cleaner, and degumming liquid that can remove hot melt glue and oil stains. The cleaning liquid is stored in the liquid storage member 41, and the metering pump 42 can adjust the liquid output according to the size of the wiping area of the workpiece and the size of the cleaning cloth. The cleaning liquid passes through the metering pump 42 and then is filtered by the filter 43 and then reaches the liquid spraying assembly 44 for liquid spraying. At least one spray head 441 for spraying liquid is arranged on the liquid spraying assembly 44, and the number of spray heads 441 can be adjusted according to the size of the workpiece. It can be understood that if the wiping area of the workpiece is relatively narrow, the width of the cleaning cloth can be correspondingly narrowed, the liquid output adjusted by the metering pump 42 is also correspondingly reduced, and the number of spray heads 441 is also reduced. When the wiping area of the workpiece is relatively large, the width of the cleaning cloth is correspondingly increased, the liquid output adjusted by the metering pump 42 is also correspondingly increased, and the number of spray heads 441 can also be correspondingly increased.

[0053] Please refer to Figures 9 to 11, in some alternative embodiments, the cleaning mechanism 50 is movably disposed on the fixed seat 102 through a mounting plate 501, and the entire cleaning mechanism 50 can be lifted and lowered along with the lifting of the mounting plate 501. Among them, the cleaning mechanism 50 includes a first guiding component 51, a first clamping component 52, a cleaning component 53, and a second clamping component 54 disposed on the mounting plate 501. The first guiding component 51 guides the cleaning belt on the feeding mechanism 20 to the first clamping component 52. The first guiding component 51 includes two first guiding wheels 511 arranged side by side. The cleaning cloth passes between the two first guiding wheels 511 and reaches the cleaning component 53 through the first clamping component 52. The first clamping component 52 and the second clamping component 54 are used to clamp the cleaning belt to position the cleaning belt on the cleaning component 53 so as to clean the workpiece on the feeding mechanism 10. The first clamping component 52 includes a second guiding wheel 521, a first clamping block 522, and a first cylinder 523. The first clamping block 522 is in the shape of a triangular prism and is fixed to the mounting plate 501. The second guiding wheel 521 is connected to the first cylinder 523, and the first cylinder 523 is fixed to the mounting plate 501. The first cylinder 523 acts to move the second guiding wheel 521 closer to the first clamping block 522 to clamp the cleaning cloth; or the first cylinder 523 acts to move the second guiding wheel 521 away from the first clamping block 522 so that the cleaning cloth can be conveyed between the second guiding wheel 521 and the first clamping block 522. The second clamping component 54 is disposed opposite to the first clamping component 52 at both ends of the mounting plate 501. The second clamping component 54 includes a third guiding wheel 541, a second clamping block 542, and a second cylinder 543.

The second cylinder 543 acts to move the third guiding wheel 541 closer to the second clamping block 542 to clamp the cleaning cloth; or the second cylinder 543 acts to move the third guiding wheel 541 away from the second clamping block 542 so that the cleaning cloth can be conveyed between the third guiding wheel 541 and the second clamping block 542.

[0054] Please refer to Figure 11, in some alternative embodiments, the cleaning assembly 53 includes a cleaning wheel 532 detachably disposed on the mounting plate 501. The size of the cleaning wheel 532 is installed according to the shape and size of the workpiece. A quick-release button 531 is provided on the cleaning wheel 532. Through the quick-release button 531, the cleaning wheel 532 can be quickly replaced, and can also be quickly installed and fixed. The outer layer of the cleaning wheel 532 can be wrapped with silicone or other soft materials to prevent the workpiece from being damaged when cleaning the workpiece. Specifically, the cleaning belt is wound around one end of the cleaning wheel 532 close to the workpiece, and the workpiece or the cleaning wheel 532 moves so that the cleaning belt acts on the workpiece for cleaning. It can be understood that a cleaning cloth is wound around the cleaning wheel 532, and the feeding mechanism 10 or the cleaning mechanism 50 moves so that the cleaning cloth can wipe and clean the workpiece. Two or more cleaning wheels 532 can be provided simultaneously, and a cleaning belt can be wound around each cleaning wheel 532 to clean different parts of the workpiece simultaneously to improve the cleaning efficiency. Or cleaning belts are wound around different areas on the cleaning wheel 532 to clean different parts of the workpiece simultaneously to improve the cleaning efficiency.

[0055] Please refer to Figures 9 to 12 , in some alternative embodiments, the mounting plate 501 is connected to a third driving assembly 56 that drives the cleaning mechanism 50 to lift and lower. The third driving assembly 56 acts so that the mounting plate 501 and each component mounted on the mounting plate 501 are lifted and lowered as the mounting plate 501 is lifted and lowered. Among them, a pressure sensor 55 is provided between the mounting plate 501 and the third driving assembly 56 to monitor the pressure exerted by the cleaning assembly 53 on the workpiece through the pressure sensor 55. When the cleaning wheel 532 cleans the workpiece, the weight of the cleaning mechanism 50 acts on the workpiece through the cleaning wheel 532. The pressure sensor 55 is provided to monitor the pressure exerted by the cleaning wheel 532 on the workpiece to prevent the workpiece from being damaged during cleaning. Specifically, to prevent the gravity of the entire cleaning mechanism 50 from acting on the workpiece, the cleaning mechanism 50 is further connected to a counterweight mechanism 60. The counterweight mechanism 60 includes a connecting member 61, a support assembly 63, and a counterweight assembly 64. One end of the connecting member 61 is connected to the mounting plate 501, and the other end of the connecting member 61 is connected to the counterweight assembly 64 through a counterweight rope 62. The counterweight block on the counterweight assembly 64 is slidably disposed on the mounting plate 501 through a slide rail assembly 65. One end of the connecting block connected to the counterweight assembly 64 is further connected to a support assembly 63 to support the mounting plate 501 and each component located on the mounting plate 501 through the support assembly 63. The number of counterweight blocks in the counterweight assembly 64 can be adjusted according to the weight of the cleaning mechanism 50. The counterweight of the counterweight mechanism 60 is used to offset the self-weight of the cleaning mechanism 50 to prevent the weight of the cleaning mechanism 50 from directly acting on the workpiece.

[0056] Please refer to Figure 13, the present invention also provides a cleaning method 200 for cleaning a workpiece using the above-mentioned cleaning device 100, which is characterized by including the following steps:

[0057] S000 Adjust the metering pump 42 on the liquid spraying mechanism 40 according to the shape and size of the workpiece, and set an appropriate number of nozzles 441. At the same time, replace the cleaning wheel 532 with an appropriate size. And replace the cleaning belt with an appropriate size according to the size of the workpiece to be cleaned, so that the cleaning liquid can act better on the cleaning belt and avoid waste.

[0058] S001 Cooperate the feeding mechanism 20 and the receiving mechanism 30 with the cleaning mechanism 50 to wind the cleaning belt around the cleaning mechanism 50; before cleaning, debug the transmission route of the cleaning belt to better perform cleaning.

[0059] S002 Use the liquid spraying mechanism 40 to spray liquid on the cleaning belt before it passes around the cleaning mechanism 50, and the feeding mechanism 20 and the receiving mechanism 30 act to make the cleaning belt passing around the cleaning mechanism 50 adhere to the cleaning liquid. When the cleaning belt sprayed with the cleaning liquid winds around the cleaning wheel 532, the first clamping assembly 52 and the second clamping assembly 54 act to position the cleaning belt on the cleaning wheel 532, and the feeding mechanism 10 acts to make the cleaning belt act on the workpiece.

[0060] Before the cleaning belt reaches the cleaning wheel 532, it is first sprayed and immersed with the cleaning liquid through the liquid spraying mechanism 40 to enable the cleaning belt to better remove glue or oil stains. When the cleaning belt with the cleaning liquid reaches the cleaning wheel 532, the first clamping assembly 52 and the second clamping assembly 54 act to position the cleaning belt on the cleaning wheel 532, and then the feeding mechanism 10 acts to make the cleaning belt act on the workpiece for cleaning.

[0061] S003 Place the workpiece on the feeding member 14 of the feeding mechanism 10, and actuate the first moving assembly 11, the second moving assembly 12, and the rotating assembly 13 on the feeding mechanism 10 to move the workpiece closer to the cleaning mechanism 50 for cleaning.

[0062] The cleaning mechanism 50 and / or the feeding mechanism 10 act so that the cleaning belt acts on the workpiece for cleaning. After the cleaning belt acts on the workpiece once, the third driving assembly 56 acts to lift the cleaning mechanism 50, and the pulling assembly 33 acts to send the used cleaning belt away from the cleaning wheel 532, and then convey the cleaning belt sprayed with cleaning liquid to the cleaning wheel 532. The cleaning belt is fed in a cycle for multiple times to complete the cleaning of the preset area of the workpiece. It can be understood that the third driving assembly 56 acts to lift the cleaning mechanism 50, and the pulling assembly 33 acts to send the used cleaning belt away from the cleaning wheel 532, and then convey the cleaning belt sprayed with cleaning liquid to the cleaning wheel 532; so as to prevent the cleaned cleaning belt from wiping the workpiece again, avoid secondary contamination, and achieve a better cleaning effect. The preset area of the workpiece is the area where the cleaning wheel 532 can clean the workpiece through the cleaning belt when the workpiece and the cleaning wheel 532 are in relative motion.

[0063] The rotating assembly 13 on the feeding mechanism 10 acts to adjust the part of the workpiece to be cleaned, and the cleaning mechanism 50 and the feeding mechanism 10 act in a cycle until the workpiece is cleaned. It can be understood that there are multiple parts on the workpiece that need to be cleaned, and the rotating assembly 13 can drive the workpiece to rotate to clean different parts of the workpiece.
