[0020] The present invention is further described in detail below in conjunction with embodiments and drawings, but the embodiments of the present invention are not limited thereto.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense, and those skilled in the art can understand the specific meanings of the above terms in the present invention in specific circumstances. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0022] like Figures 1 to 6 As shown, the small-size cover cleaning machine comprises a frame 10 and a control box 20. The control box 20 is used to control the operation state of the entire device so that each mechanism cooperates with each other to complete the cleaning work of the small-size cover.

[0023] The frame 10 is provided with a feed port 50, a first wind shear chamber 51, a first cleaning area 52, a second wind shear chamber 53, a second cleaning area 54, a third wind shear chamber 55, a third cleaning area 56, a fourth cleaning area 57, a fifth cleaning area 58, a fourth wind shear chamber 59, and a discharge port 60 in sequence. The frame 10 is also provided with a conveying mechanism 30 and a water tank 40. The cover plate to be cleaned enters from the feed port 50 once and passes through the above-mentioned treatment chamber, and is finally taken out from the discharge port 60 after cleaning.

[0024] The conveying mechanism 30 passes through the inlet 50 and the outlet 60 of the frame 10, and includes a transmission motor 31 and a conveying roller 32 connected to the output end of the transmission motor 31. The conveying mechanism 30 includes multiple groups of conveying rollers 32. The conveying roller 32 includes a plurality of parallel and evenly arranged shaft cores 321 and a rubber ring 322 sleeved on the shaft core, and the rubber ring 322 is sleeved on two adjacent shaft cores 321 and arranged crosswise. Preferably, the rubber ring 322 is a fluororubber O-ring.

[0025] Fluorine rubber O-rings are widely used in automobiles, electronics, aerospace, ships and other fields that require high precision. They are resistant to high temperatures and wear and can work in harsh working environments. The main component is rubber containing fluorine in the molecule, which is divided into different types according to the fluorine content. Its high temperature resistance is better than that of silicone rubber, and it has excellent chemical resistance, resistance to most oils and solvents (except ketones and esters), weather resistance and ozone resistance.

[0026] The water tank 40 supplies water to the first cleaning area 52, the second cleaning area 54, the third cleaning area 56, the fourth cleaning area 57, and the fifth cleaning area 58. The first cleaning area 52, the second cleaning area 54, and the third cleaning area 56 are deionized water roller brush cleaning areas, the fourth cleaning area 57 is a deionized water spray cleaning area, and the fifth cleaning area 58 is a pure water rinse area.

[0027] The deionized water roller brush cleaning area includes a deionized water filter, a spray assembly and a roller brush assembly, the deionized water spray cleaning area includes a deionized water filter and a spray assembly, and the pure water flushing area includes a pure water filter and a spray assembly.

[0028] The spray assembly includes a spray pipe arranged on the upper and lower sides of the cover plate and a nozzle arranged on the spray pipe. The water inlet of the deionized water filter is connected to the water tank 40, and the water outlet is connected to the spray pipe. The water in the water tank 40 flows out through the deionized water filter or the pure water filter, and then sprays out from the nozzle through the spray pipe. The nozzle is preferably an umbrella-shaped nozzle, and 2-3 nozzles are evenly arranged on each spray pipe. The roller brush assembly includes an upper roller brush and a lower roller brush arranged on the upper and lower sides of the cover plate. The upper roller brush contacts the upper surface of the cover plate, and the lower roller brush contacts the lower surface of the cover plate.

[0029] Preferably, the filtration accuracy of the water used in the first cleaning area 52, the second cleaning area 54, the third cleaning area 56, the fourth cleaning area 57, and the fifth cleaning area 58 is 10μm, 5μm, 5μm, 1μm, and 0.5μm, respectively. The cover plate passes through the cleaning chambers with increasingly higher filtration accuracy in turn, and the impurities in the cleaning water are gradually reduced, thereby improving the final cleaning effect. The water used in the third cleaning area 56 and the second cleaning area 54 is preferably of the same filtration accuracy, and the significance is to add the third cleaning area 56 with the same cleaning intensity to consolidate and strengthen the cleaning effect of the second cleaning area 54.

[0030] A filter assembly 41 is provided between the deionized water filter, the pure water filter and the water tank 40. The filter assembly 41 is composed of two annular clamping plates 411 and a stainless steel filter screen 412. The filter screen 412 is sandwiched between the two annular clamping plates 411. The filter assembly 41 can pre-filter out large particles of impurities entering the water tank 40, reduce the filtering pressure of the rear equipment and reduce the loss of the equipment overload. Here, the filter screen 412 is preferably a 304 stainless steel filter screen 412, and the annular clamping plate 411 is connected to the water tank 40 by spot welding.

[0031] The first wind shear chamber 51, the second wind shear chamber 53, and the third wind shear chamber 55 include drying wind knives arranged on the upper and lower sides of the cover plate, and the direction of the drying wind knife air outlet is parallel to the conveying direction of the cover plate. The first wind shear chamber 51, the second wind shear chamber 53, and the third wind shear chamber 55 are arranged alternately with the first cleaning area 52, the second cleaning area 54, and the third cleaning area 56, with a single "drying-cleaning" as a cleaning operation unit, and the cleaning effect is gradually enhanced in combination with the filtering accuracy of different cleaning chambers. The drying effect of the wind shear chamber ensures that when the cover plate enters the next cleaning chamber for cleaning, there is no residual water from the previous cleaning unit on the surface, so as to carry out the next cleaning with higher cleanliness. The fourth wind shear chamber 59 includes four groups of drying wind knives, and the four groups of drying wind knives are evenly distributed on the upper and lower sides of the cover plate, and the air outlet direction is at an angle of 0-5° to the conveying direction of the cover plate. The fourth wind shear chamber 59 is located in the last step of the entire cleaning process. Its function is to air dry all the water residue on the surface of the cover plate after cleaning, and at the same time prevent the residual water on the cover plate from being taken out from the discharge port 60 and then absorbing the particulate impurities suspended in the air to cause secondary pollution.

[0032] Specifically, the drying air knife is powered by a high-pressure air pump, which compresses and heats the air and blows it out from the drying air knife. The air inlet of the high-pressure air pump is equipped with an air filtration system to filter out dust, impurities and static electricity in the air. Correspondingly, an air distributor and an air volume regulating valve are provided between the drying air knife and the high-pressure air pump, and an air pressure gauge is provided in each air cutting room to monitor the air pressure in real time.

[0033] Specifically, a roller brush motor is also provided on the frame 10 to drive the roller brush to rotate. A solenoid valve is provided at the water inlet of the water tank 40, and the remaining water in the water tank 40 can be autonomously monitored in real time through the sensor to realize automatic water supply. In addition, each cleaning area is also provided with a temperature control system for water heating. The deionized water filter, the pure water filter, the roller brush motor and the transmission motor 31 are electrically connected to the control box 20 respectively. The control box 20 is correspondingly provided with an operating table on the frame 10. During the operation of the equipment, the operator can control the working status of each component through the operating table. Specifically, the operating table includes but is not limited to the motor emergency stop button, the motor speed control button, the water tank 40 automatic water supply, the temperature control, the wind pressure control and other function buttons.

[0034] The specific implementation of the present invention is as follows:

[0035] After the equipment is installed according to the structure described above, it enters the waiting state. After the equipment is started, the conveying mechanism 30 is operated, and the cover plate to be cleaned is placed on the inlet 50. The conveying motor drives the conveying roller 32 to operate, and the shaft core 321 of the conveying roller 32 rotates to drive the rubber ring 322 to operate so that the cover plate moves to one end of the discharge port 60. On the way, it passes through the first wind shear chamber 51, the first cleaning area 52, the second wind shear chamber 53, the second cleaning area 54, the third wind shear chamber 55, and the third cleaning area 56 in sequence for three rounds of deionized water cleaning and drying with increasing purity, and then passes through the fourth cleaning area 57 for spray cleaning with higher purity deionized water, and the fifth cleaning area 58 for pure water cleaning, and finally passes through the four groups of drying air knives in the fourth wind shear chamber 59 to dry and remove the water droplets on the surface of the cover plate, and then the cleaned cover plate is taken out from the discharge port 60 to complete the cleaning process of the cover plate.

[0036] The above-mentioned embodiments only express the implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
