[0028] The following refers to Figures 1 to 3 to describe the cleaning system of the present application in detail.

[0029] Refer to Figure 1 and Figure 3, A cleaning system according to an embodiment of the present invention includes a first spraying module 100, an ultrasonic cleaning module 200, a second spraying module 300, a first transfer module 400, a second transfer module 500, and a transfer module 600; the first spraying module 100 has a first spraying area, and the first spraying module 100 is further provided with a first spraying port and a first drainage port communicating with the first spraying area; the ultrasonic cleaning module 200 has an ultrasonic cleaning area, and the ultrasonic cleaning module 200 is further provided with a liquid inlet and a second drainage port communicating with the ultrasonic cleaning chamber; the second spraying module 300 has a second spraying area, and the second spraying module 300 is further provided with a second spraying port and a third drainage port communicating with the second spraying area; a first water inlet of the first transfer module 400 is communicated with the third drainage port, and a first water outlet of the first transfer module 400 is communicated with the liquid inlet; a second water inlet of the second transfer module 500 is communicated with the second drainage port, and a second water outlet of the second transfer module 500 is communicated with the first spraying port; the transfer module 600 is used to drive the workpiece to sequentially pass through the first spraying area, the ultrasonic cleaning area, and the second spraying area.

[0030] For example, as Figure 1 and Figure 3 shown, the first spraying module 100, the ultrasonic cleaning module 200, and the second spraying module 300 are arranged from left to right, and the transfer module 600 is used to drive the workpiece to sequentially pass through the first spraying area, the ultrasonic cleaning area, and the second spraying area from left to right.

[0031] It should be noted that during the process of the workpiece sequentially passing through the first spraying area, the ultrasonic cleaning area, and the second spraying area, the impurities on the surface of the workpiece will become less and less. Correspondingly, the impurities contained in the water discharged from the first spraying area, the ultrasonic cleaning area, and the second spraying area will also become less and less.

[0032] It can be understood that in the cleaning system of the present application, after the water cleans the workpiece in the second spraying area, it can sequentially enter the ultrasonic cleaning area through the third drainage port, the first transfer module 400, and the liquid inlet to clean the workpiece in the ultrasonic cleaning area again. After that, the water can sequentially pass through the second drainage port, the second transfer module 500, and the first spraying port to enter the first spraying area to clean the workpiece in the first spraying area again; furthermore, in the cleaning system of the present application, the water can be used multiple times. On the premise of ensuring that the cleaning system of the present application can clean the workpiece cleanly, the water consumption of the cleaning system of the present application is lower.

[0033] In some embodiments of the present invention, the cleaning system further includes a third spraying module 700 and a third transfer module 800. The third spraying module 700 has a third spraying area, and the third spraying module 700 is further provided with a third spraying port and a fourth drainage port communicating with the third spraying area. The second water inlet of the third transfer module 800 is communicated with the fourth drainage port, and the third water outlet of the third transfer module 800 is communicated with the second spraying port. The transfer module 600 is used to drive the workpiece to sequentially pass through the first spraying area, the ultrasonic cleaning area, the second spraying area, and the third spraying area.

[0034] For example, as Figure 1 and Figure 3 shown, the cleaning system further includes a third spraying module 700, and the third spraying module 700 is located on the right side of the second spraying module 300. After the workpiece is cleaned in the second spraying area of the second spraying module 300, the transfer module 600 can drive the workpiece from the second spraying area of the second spraying module 300 into the third spraying area of the third spraying module 700 to clean the workpiece again.

[0035] It can be understood that by setting the third spraying module 700, the third spraying module 700 can clean the workpiece after being cleaned by the second spraying module 300 again to improve the cleaning quality of the workpiece by the cleaning system of the present application.

[0036] It can be understood that the setting of the third transfer module 800 enables the third spraying module 700 to transfer the water discharged from the third spraying area to the second spraying area to clean the workpiece in the second spraying area after the water in the third spraying area is used to clean the workpiece, thereby improving the utilization rate of water in the cleaning system of the present application and further reducing the water consumption of the cleaning system of the present application.

[0037] In some embodiments of the present invention, referring to Figure 3 , the first transfer module 400 includes a water storage tank 410 and an overflow tank 420. The water inlet of the overflow tank 420 is communicated with the overflow port of the water storage tank 410. The water inlet of the water storage tank 410 forms a first water inlet, and the drainage port of the overflow tank 420 forms a first water outlet.

[0038] It can be understood that the water discharged from the second spraying area can first enter the water storage tank 410 for precipitation. The water overflowing from the water storage tank 410 can flow into the overflow tank 420 for use in the ultrasonic cleaning area. Since part of the impurities in the water will precipitate in the water storage tank 410, the cleanliness of the water entering the ultrasonic cleaning area is improved.

[0039] It can be understood that since the water in the water storage tank 410 overflows into the overflow tank 420, even if the water in the overflow tank 420 is used up, there will still be a certain amount of water stored in the water storage tank 410 of the first transfer module 400 for use.

[0040] It should be noted that the specific structures of the second transfer module 500 and the third transfer module 800 refer to the first transfer module 400.

[0041] In some embodiments of the present invention, referring to Figure 2 , the ultrasonic cleaning module 200 includes a water storage tank 210 and an ultrasonic generator 220. An ultrasonic cleaning area is formed in the water storage tank 210. The ultrasonic generator 220 is disposed in the water storage tank 210 and is used to vibrate the liquid in the water storage tank 210.

[0042] It can be understood that water is stored in the water storage tank 210. After the transfer module 600 transports the workpiece into the water storage tank 210, the ultrasonic generator 220 can operate to cause the water in the water storage tank 210 to vibrate, thereby completing the cleaning of the workpiece in the water storage tank 210.

[0043] In a further embodiment of the present invention, the transfer module 600 includes a conveyor belt 610 for transporting workpieces.

[0044] For example, as Figure 2 shown, the transfer module 600 includes a conveyor belt 610 extending from left to right. The workpiece is carried on the conveyor belt 610. Under the conveyance of the conveyor belt 610, the workpiece sequentially passes through the first spraying area, the ultrasonic cleaning area, and the second spraying area from left to right.

[0045] In order to enable the conveyor belt 610 to drive the workpiece to stably enter below the liquid level of the water storage tank 210, in some embodiments of the present invention, the ultrasonic cleaning module 200 further includes a belt pressing structure 230. The belt pressing structure 230 is used to press the conveyor belt 610 below the liquid level of the water storage tank 210.

[0046] Specifically, referring to Figure 2 , the belt pressing structure 230 includes a mounting frame, a first set of pressing wheels 231, and a second set of pressing wheels. The first set of pressing wheels 231 and the second set of pressing wheels are distributed on the mounting frame along the width direction of the conveyor belt 610. An avoidance area allowing the workpiece to pass through is formed between the first set of pressing wheels 231 and the second set of pressing wheels. The first set of pressing wheels 231 includes a plurality of first pressing wheels spaced apart along the length direction of the conveyor belt 610. The second set of pressing wheels includes a plurality of second pressing wheels spaced apart along the length direction of the conveyor belt 610. The first pressing wheels and the second pressing wheels are both in contact with the upper surface of the conveyor belt 610 and are used to press the conveyor belt 610 below the liquid level of the water storage tank 210.

[0047] It can be understood that the first pressing wheel and the second pressing wheel can cooperate to abut against the upper surface of the conveyor belt 610. Under the action of the first pressing wheel and the second pressing wheel, the conveyor belt 610 can be pressed down to between the liquid levels of the water storage tank 210. During the process of the conveyor belt 610 driving the workpiece from the first spraying area to the second spraying area, the workpiece can enter the water storage tank 210 under the drive of the conveyor belt 610 and be completely immersed below the liquid level of the water storage tank 210. Under the action of the ultrasonic generator 220, the cleaning of the workpiece can be completed.

[0048] In some embodiments of the present invention, referring to Figure 1 and Figure 3 , the cleaning system further includes a drying module 900. The drying module 900 has a drying area for drying the workpiece. The transfer module 600 can drive the workpiece to sequentially pass through the first spraying area, the ultrasonic cleaning area, the second spraying area, and the drying area.

[0049] It can be understood that the drying module 900 also has an air outlet communicating with the drying area. After the transfer module 600 drives the workpiece into the drying area, the drying module 900 can convey dry hot air into the drying area through the air outlet to dry the workpiece in the drying area.

[0050] In some embodiments of the present invention, referring to Figure 1 and Figure 3 , the cleaning system further includes an air knife module 1000. An air knife area for blowing off the water droplets on the surface of the workpiece is formed in the air knife module 1000. The transfer module 600 can drive the workpiece to sequentially pass through the first spraying area, the ultrasonic cleaning area, the second spraying area, the air knife area, and the drying area.

[0051] It should be noted that after the workpiece passes through the second spraying area, a large amount of water droplets will adhere to the surface of the workpiece. In this case, if the workpiece directly enters the drying area, the moving process of the workpiece in the drying area is short, and the water droplets on the surface of the workpiece are difficult to completely evaporate in the drying area. As a result, when the workpiece leaves the drying area, water droplets still adhere to the surface of the workpiece.

[0052] It can be understood that in this embodiment, by arranging the air knife module 1000 between the second spraying module 300 and the drying module 900, the workpiece can enter the air knife area after leaving the second spraying area. Under the action of the air knife module 1000, most of the water droplets on the surface of the workpiece can be blown off to reduce the adhesion amount of the water droplets on the surface of the workpiece. Thus, after the workpiece enters the drying area, due to the small amount of water droplets on the surface of the workpiece, the workpiece can be dried more quickly in the drying area.

[0053] In some embodiments of the present invention, referring to Figure 1 and Figure 3, the cleaning system further includes an electrostatic elimination module 1100. An electrostatic elimination area for removing the static electricity on the surface of the workpiece is formed inside the electrostatic elimination module 1100. The transfer module 600 can drive the workpiece to sequentially pass through the first spraying area, the ultrasonic cleaning area, the second spraying area, the drying area, and the electrostatic elimination area.

[0054] It can be understood that after the drying module 900 dries the workpiece, a large amount of electric charges will be generated on the surface of the workpiece. The existence of these electric charges will make the surface of the workpiece easily adsorb impurities in the air, thus causing impurities to adhere to the surface of the workpiece again.

[0055] In this embodiment, by providing the electrostatic elimination module 1100, after the drying module 900 dries the workpiece, the electrostatic elimination module 1100 can remove the electric charges on the surface of the workpiece to reduce the probability of the surface of the workpiece adsorbing impurities again.

[0056] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
