[0030] An embodiment of the present application provides a glass cleaning device. Please refer to Figure 1 and Figure 2 , the glass cleaning device includes a box body 1, a conveying roller mechanism 2, a cleaning mechanism 3 and a drying mechanism 4. The conveying roller mechanism 2 is arranged horizontally in the box body 1, and the conveying roller mechanism 2 is used to convey glass from the inlet of the box body 1 to the outlet of the box body 1; the cleaning mechanism 3 includes a detergent brushing module 301 and a plurality of spraying modules arranged in sequence along the conveying direction of the glass. Spraying modules are arranged in front of and behind the detergent brushing module 301 along the conveying direction, and the cleanliness of the liquids sprayed by the plurality of spraying modules increases in sequence along the conveying direction; the drying mechanism 4 is arranged at the outlet of the box body 1.

[0031] Exemplarily, the glass cleaned by the glass cleaning device of the present application is subsequently subjected to TCO coating.

[0032] Optionally, the type of the glass is semiconductor glass, photovoltaic glass or optoelectronic glass, which is not uniquely limited herein.

[0033] In the embodiment of the present application, the glass cleaning device includes a box body 1, a conveying roller mechanism 2, a cleaning mechanism 3 and a drying mechanism 4. The conveying roller mechanism 2 is used to convey glass from the inlet of the box body 1 to the outlet of the box body 1. The cleaning mechanism 3 includes a detergent brushing module 301 and a plurality of spraying modules arranged in sequence along the conveying direction of the glass. Spraying modules are arranged in front of and behind the detergent brushing module 301 along the conveying direction, and the cleanliness of the liquids sprayed by the plurality of spraying modules increases in sequence along the conveying direction. The glass to be cleaned at the beginning is relatively dirty, and the use of a liquid with a relatively poor cleanliness can meet the preliminary cleaning requirements, and then gradually use a liquid with a relatively better cleanliness to ensure the final cleaning effect, so as to realize multi-stage and multi-level cleaning of the glass, while achieving reasonable resource allocation and improving the cleanliness of the glass.

[0034] On the other hand, the conveying roller mechanism 2, the cleaning mechanism 3 and the drying mechanism 4 of the present application are all integrated in the box body 1, and the installation is relatively convenient, and it can be quickly installed in a production site or other indoor spaces for automatic cleaning and drying.

[0035] In one embodiment, please refer toFigure 1 Among them, multiple spraying modules are, in sequence along the conveying direction, the first liquid cutting module 302, pure water spraying module 303, second liquid cutting module 304, third liquid cutting module 305, first high-pressure spraying module 306, second high-pressure spraying module 307, third high-pressure spraying module 308, two-fluid spraying module 309, and deionized water spraying module 310. The detergent scrubbing module 301 is arranged between the second liquid cutting module 304 and the third liquid cutting module 305.

[0036] Specifically, each liquid cutting module uses high-pressure water to wash the glass. The pure water spraying module 303 and each high-pressure spraying module are used to fully wet stubborn stains. The detergent scrubbing module 301 uses detergent to scrub stains and is the main module for removing stains.

[0037] Among them, the two-fluid sprayed by the two-fluid spraying module 309 refers to a mixture composed of two immiscible liquids, such as an oil-water mixture, hydrated oil, water hot air dry coating, etc. The reason for the existence of the two-fluid is that these two immiscible liquids have different properties such as density, surface tension, viscosity, and gas solubility, thus forming a mixture with unique fluid behavior. During the cleaning process, the high cleaning ability of the two-fluid mixture and its fluid behavior are used to clean the target surface. Specifically, two-fluid cleaning is a process of using a mixture of solvents, surfactants, etc. to clean the chemical and physical interactions formed between pollutants and the surface of the contaminated object. Two-fluid cleaning has excellent surface tension and viscosity, can form a cleaning layer that can cover and enter small pores on the target surface, and effectively remove surface pollutants; moreover, the solvent for two-fluid cleaning can be recycled, avoiding the generation of waste water and waste liquid that are difficult to handle in some iron cans, and at the same time having an energy-saving effect.

[0038] Among them, the deionized water (DI water) sprayed by the deionized water spraying module 310 refers to pure water from which impurities in ionic form have been removed, and has a high purity, which can effectively improve the cleaning effect.

[0039] In one embodiment, a first liquid receiving tank body is arranged below the pure water spraying module 303, a second liquid receiving tank body is arranged below the detergent scrubbing module 301, a third liquid receiving tank body is arranged below the first high-pressure spraying module 306, a fourth liquid receiving tank body is arranged below the second high-pressure spraying module 307, a fifth liquid receiving tank body is arranged below the third high-pressure spraying module 308, and a sixth liquid receiving tank body is arranged below the two-fluid spraying module 309.

[0040] By the above settings, the liquid receiving tank body can prevent liquid from accumulating in the box body 1. A liquid receiving tank body is provided at the bottom of each spraying module to collect the used liquid, and it can also determine whether to collect the liquid into the waste water bucket or reuse it according to the degree of liquid pollution, achieving reasonable allocation of resources and flexible use.

[0041] In one embodiment, a first liquid storage tank body 311 communicating with the first liquid receiving tank body is provided on the side of the first liquid receiving tank body, a second liquid storage tank body 312 communicating with the second liquid receiving tank body is provided on the side of the second liquid receiving tank body, a third liquid storage tank body 313 communicating with the third liquid receiving tank body is provided on the side of the third liquid receiving tank body, a fourth liquid storage tank body 314 communicating with the fourth liquid receiving tank body is provided on the side of the fourth liquid receiving tank body, a fifth liquid storage tank body 315 communicating with the fifth liquid receiving tank body is provided on the side of the fifth liquid receiving tank body, and a sixth liquid storage tank body 316 communicating with the sixth liquid receiving tank body is provided on the side of the sixth liquid receiving tank body.

[0042] Furthermore, the glass cleaning device further includes a safety alarm system. The safety alarm system includes an alarm lamp provided on the box body 1 and liquid level alarms provided in each liquid receiving tank body and each liquid storage tank body, which can prevent liquid from overflowing into the box body 1 and causing pollution or corrosion to the box body 1, and avoid increasing additional workload.

[0043] In one embodiment, please refer to Figure 1 that the liquid in the sixth liquid storage tank body 316 can overflow into the fifth liquid storage tank body 315, the liquid in the fifth liquid storage tank body 315 can overflow into the fourth liquid storage tank body 314, and the liquid in the fourth liquid storage tank body 314 can overflow into the third liquid storage tank body 313.

[0044] Specifically, the purity of the liquid in the sixth liquid storage tank body 316 is higher than that of the liquid in the fifth liquid storage tank body 315. Therefore, the liquid in the sixth liquid storage tank body 316 overflowing into the fifth liquid storage tank body 315 for reuse will not affect the quality of the liquid in the fifth liquid storage tank body 315; similarly, the liquid in the fifth liquid storage tank body 315 overflowing into the fourth liquid storage tank body 314 for reuse will not affect the quality of the liquid in the fourth liquid storage tank body 314, and the liquid in the fourth liquid storage tank body 314 overflowing into the third liquid storage tank body 313 for reuse will not affect the quality of the liquid in the third liquid storage tank body 313. In this way, the used liquid with higher purity is transported forward to the area with lower purity requirements for reuse, improving the resource utilization rate and reducing the cost.

[0045] Furthermore, each liquid storage tank body is externally connected with a liquid supplementing system, and the connection between the liquid supplementing system and the liquid storage tank body is sealed.

[0046] In one embodiment, please refer to Figure 2, the glass cleaning device further includes a reciprocating motion mechanism 6 disposed at the detergent scrubbing module 301. The reciprocating motion mechanism 6 includes an upper clamping rotating shaft 601 and a lower clamping rotating shaft 602 spaced apart in the vertical direction. The end of the upper clamping rotating shaft 601 and / or the lower clamping rotating shaft 602 is connected to a rotary drive mechanism. The rotary drive mechanism alternately rotates forward and backward to drive the upper clamping rotating shaft 601 and the lower clamping rotating shaft 602 to clamp the glass and make a reciprocating linear motion.

[0047] In this way, the glass at the detergent scrubbing module 301 makes a reciprocating linear motion under the clamping of the reciprocating motion mechanism 6, which can effectively improve the cleaning effect.

[0048] In one embodiment, please refer to Figure 1 , the detergent scrubbing module 301 and at least part of the spraying module are provided with nozzles both above and below the glass, which can effectively improve the cleaning effect.

[0049] In one embodiment, the glass cleaning device further includes a plurality of linear drive mechanisms corresponding to the detergent scrubbing module 301 and a plurality of spraying modules. The linear drive mechanism is used to drive the detergent scrubbing module 301 or the spraying module to move in the vertical direction.

[0050] With the above settings, the heights of the detergent scrubbing module 301 and the plurality of spraying modules are adjustable. Not only can the spraying distance be adjusted according to the glass thickness to improve the adaptability to various types of products, but also the spraying distance can be adjusted according to the cleaning requirements to enrich the working parameters of the glass cleaning device.

[0051] In one embodiment, please refer to Figure 1 , the glass cleaning device further includes an electrostatic elimination mechanism 5 disposed at the outlet of the box body 1. The electrostatic elimination mechanism 5 can eliminate the static electricity on the glass after drying is completed, reducing the possibility of dust adhering to the glass here.

[0052] In one embodiment, the glass cleaning device further includes a counting sensor, a temperature sensor and a timing sensor disposed in the box body 1.

[0053] With the above settings, the functions of automatic large-batch cleaning, counting and air drying can be realized. The working process is all carried out in the box body 1, effectively preventing potential safety hazards for operators. Through the monitoring of each sensor, the cleaning process can be fully automatic, eliminating human interference, and the cleaning is safe, thorough, standardized, convenient and fast.

[0054] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0055] The embodiments described above merely represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patented application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
