Description

Technical Field

[0001] The present invention relates to the technical field of glass processing, and particularly to a cleaning device and a using method for coated glass processing. Background Art

[0002] Cleaning before coated glass processing (especially offline Low-E, solar control coating, etc.) is an extremely crucial process, which directly determines the quality and performance of the final coating.

[0003] The core objectives of cleaning are: Thoroughly remove contaminants: Remove all physical and chemical contaminants adhering to the glass surface during processes such as cutting, edging, drilling, transportation, and storage, including: Dust and particulate matter: Glass powder, environmental dust, fibers, etc.

[0004] Oils and fingerprints: Residues from operator contact and equipment lubricating oils.

[0005] Organic residues: Cutting oil, residue of protective film adhesive, residue of packaging materials, etc.

[0006] Inorganic residues: Salts, scale, oxides, etc. in the edge grinding coolant.

[0007] Moisture: Residual water stains and water marks.

[0008] Form a highly active surface: The glass surface after cleaning needs to have extremely high cleanliness and hydrophilicity (good wettability) to ensure uniform adhesion and excellent performance (low emissivity, high light transmittance, uniform color, etc.) of subsequent coatings (such as magnetron sputtering).

[0009] Avoid film layer defects: Any remaining contaminants (even invisible to the naked eye) may cause problems such as pinholes, spots, rainbow patterns, poor adhesion, uneven color, and poor conductivity in the coating layer, and even lead to the scrapping of the entire piece of glass.

[0010] Currently, most of the existing technologies have a fixed spraying range and cannot adapt to glass of different widths. A large amount of water is wasted when cleaning narrow glass, and the edges of wide glass are not thoroughly cleaned; there are defects in water curtain control. When adjusting, there will be a water cut-off phenomenon, and uneven coverage is caused by changes in water pressure. Mechanical components are prone to scaling and damage; the precision control is insufficient. The spring system adjustment is inaccurate, and there are problems of rebound and oscillation.

[0011] In view of this, we propose a cleaning device and a using method for coated glass processing. Summary of the Invention

[0012] The object of the present invention is to provide a cleaning device and a usage method for coated glass processing, so as to solve the problems of fixed spraying range, water curtain control defects, and insufficient precision control in the prior art mentioned in the above background technology. To achieve the above object, the present invention provides the following technical solution: A cleaning device for coated glass processing, including a cleaning table, and two side rails are symmetrically arranged on the top of the cleaning table. A roller for conveying glass from left to right is arranged between the two side rails, and suspensions are fixedly arranged on both side rails. A main water pipe is fixedly installed between the two suspensions, and a plurality of spray nozzles are arranged at the bottom of the main water pipe.

[0013] The spray washer regulator includes a notch opened along the top of the side rail, and a slide rail is arranged in the notch. A slide frame is slidably connected in the slide rail, and the part of the slide frame located above the roller is set as an inclined plate. A chute is opened on the inner bottom wall of the notch, and a slide post is slidably connected in the chute. A limiting spring is arranged in the chute, and the limiting spring pushes the slide post to slide towards the direction of the glass to limit the inclined plate.

[0014] Both ends of the main water pipe are fixedly provided with ring sleeves with openings at the bottom, and the two ring sleeves are distributed in an opposite and staggered manner along the left and right sides of the main water pipe.

[0015] A sub-water pipe with both ends closed is slidably connected in the ring sleeve, and a plurality of spray nozzles are also arranged at the bottom of the sub-water pipe. The slide frame is fixedly connected to the sub-water pipe through a connecting rod.

[0016] An outlet communicating with the main water pipe is opened inside the ring sleeve. A plurality of water inlets are opened on the side surface of the sub-water pipe and are matched with the outlet, and the plurality of water inlets correspond to the plurality of spray nozzles on the sub-water pipe one by one.

[0017] A ring seat is fixedly arranged inside the sub-water pipe between adjacent two spray nozzles. A ring seat is also fixedly arranged in the water inlet, and a groove is opened on the surface of the ring seat. A one-way sealing cover that rotates in a one-way manner is rotatably connected in the groove.

[0018] A water curtain adjustment component is arranged in the spray nozzle.

[0019] Preferably, the water curtain adjustment component includes a hollow valve head fixedly installed in the spray nozzle, and a fan shell is fixedly arranged at the bottom of the hollow valve head. A fan groove is opened inside the fan shell, and the bottom of the fan groove communicates with the outside. An inner hole is opened at the top of the fan shell, and the inner hole communicates the fan groove with the hollow valve head.

[0020] Two fan plates are slidably connected in the fan groove, and sealing plates that are matched with each other are fixedly connected to the relative sides of the surfaces of the two fan plates. The area between the two sealing plates and the two fan plates is set as a spray hole.

[0021] A slide plate is slidably connected inside the hollow valve head, and a top spring is arranged inside the hollow valve head. The top spring pushes the slide plate to move upward, and a sleeve with internal threads is fixedly arranged at the bottom of the slide plate.

[0022] A rotating shaft with threads on the upper side is rotatably connected inside the inner hole through a bracket, and the upper shaft body of the rotating shaft is assembled inside the sleeve through threads.

[0023] The bottom end of the rotating shaft is fixedly connected with a gear, and fan-shaped distributed tooth grooves meshing with the gear are arranged on the side surface of the fan plate.

[0024] A speed regulating component for controlling the downward movement speed of the slide plate is arranged on the hollow valve head.

[0025] Preferably, the speed regulating component includes a micro electric cylinder fixedly installed on the side surface of the hollow valve head, and a sleeve is fixedly connected to the side surface of the hollow valve head. A gas plug is slidably connected inside the sleeve, and the telescopic rod of the micro electric cylinder is fixedly connected with the gas plug.

[0026] An air bag is fixedly arranged inside the hollow valve head, and the air bag is located below the slide plate. An air hole communicating the air bag with the sleeve is arranged on the hollow valve head.

[0027] Preferably, a hoop is arranged on the suspension, and the main water pipe is fixed through the hoop.

[0028] Preferably, the connecting rod and the auxiliary water pipe are fixed through bolts.

[0029] Preferably, a tapered edge is fixedly arranged at the bottom edge of the fan plate on the side opposite to the spray holes.

[0030] Preferably, the inside of the spray port is set as a threaded interface, and the hollow valve head is screwed into the threaded interface.

[0031] A usage method of a cleaning device for processing coated glass includes the following steps: S1. Place the coated glass on the roller, and the rotating roller conveys the coated glass from left to right. During this process, water is conveyed into the main water pipe by an external water pump and sprayed downward along the spray port to wash the coated glass. S2. When the coated glass is conveyed along the roller, its side contacts the inclined plate and squeezes the sliding frame to slide outward along the slide rail. During this process, the auxiliary water pipe slides outward synchronously with the sliding frame. The width of the glass corresponds to the moving amount of the auxiliary water pipe, and the water inlets at different positions are aligned with the water outlets. The water in the main water pipe enters the auxiliary water pipe along the water inlets and then sprays out along the corresponding spray ports. Moreover, the water in the auxiliary water pipe can push open the upper-stage one-way sealing cover, enabling the upper-stage spray ports passing through the ring sleeve to spray water synchronously, while being unable to push open the lower-stage one-way sealing cover. S3. The water in the nozzle is injected into the hollow valve head and enters the spray holes along the inner hole and sprays out. During this process, increasing the water pressure can push the slide plate to compress the top spring and move downward, and make the sleeve move downward to drive the rotating shaft to rotate. The following rotating gear then pushes the two fan plates to slide away from each other along the tooth grooves. At this time, the two sealing plates move relatively away from each other, increasing the spray width of the spray holes. S4. When the slide plate moves downward, start the electric cylinder to drive the air plug to move downward. The air plug injects air into the airbag along the sleeve, so that the gas in the airbag is compressed. At this time, the hardness of the airbag increases, and the downward movement speed of the slide plate squeezing the airbag slows down, that is, the adjustment speed of the water curtain width of the spray hole becomes slower.

[0032] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, the dynamic spray range adjustment system realizes the real-time adaptive adjustment of the spray width through the linkage design of the carriage-inclined plate mechanical induction mechanism and the secondary water pipe. When the glass edge touches the inclined plate, it pushes the carriage to drive the secondary water pipe to move outward, so that the water inlet at a specific position is accurately aligned with the water outlet of the main water pipe. The one-way sealing cover group ensures that the water flow is only supplied to the working area in a directional manner, forming a spray zone that precisely matches the width of the glass. The actual measurement shows that this design improves the water-saving effect compared with the traditional fixed nozzle and avoids the spray blind area at the edge.

[0033] In the present invention, the water pressure-driven water curtain control mechanism adopts a hydraulic-mechanical conversion system. When the water pressure exceeds, it pushes the slide plate to move downward, and converts the linear motion into the rotational motion of the gear through the threaded sleeve, driving the sector gear plate to realize stepless adjustment of the spray hole width. This mechanism enables the water curtain coverage area to change dynamically, and always maintains continuous spraying during the adjustment process, solving the problem of cleaning interruption existing in the traditional deflection nozzle and improving the uniformity of the water film on the glass surface.

[0034] In the present invention, the pneumatic damping precision speed regulation system precisely controls the air pressure in the airbag through a micro electric cylinder to form a programmable damping effect. When the water pressure fluctuates, the volume change of the compressed gas in the airbag generates a progressive resistance, enabling the moving speed of the slide plate to be accurately regulated within a certain range. Compared with the spring damping, this scheme eliminates the elastic hysteresis phenomenon, improves the adjustment accuracy of the spray hole width, and the air pressure adjustment and water pressure drive can operate independently, realizing the two-stage control of coarse adjustment - fine adjustment.

Detailed implementation manners

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical staff in the art without creative work belong to the protection scope of the present invention.

[0038] Please refer to Figures 1 to 11, the present invention provides a technical solution: a cleaning device for processing coated glass, including a cleaning table 1, and two side rails 2 are symmetrically arranged on the top of the cleaning table 1. A roller 3 for conveying glass from left to right is arranged between the two side rails 2. The coated glass is placed on the roller 3, and the rotating roller 3 conveys the coated glass from left to right. Suspensions 4 are fixedly arranged on both side rails 2, a main water pipe 5 is fixedly installed between the two suspensions 4, and a number of spray nozzles 6 are arranged at the bottom of the main water pipe 5. Water is conveyed into the main water pipe 5 by an external water pump and sprayed downward along the spray nozzles 6 to wash the coated glass. A spray regulator 7 for adjusting the spray range according to the width of the glass is arranged on the side rail 2.

[0039] The spray regulator 7 includes a notch 71 opened along the top of the side rail 2, a slide rail 72 is arranged in the notch 71, a carriage 73 is slidably connected in the slide rail 72, and the part of the carriage 73 located above the roller 3 is set as an inclined plate 74. A chute 75 is opened on the inner bottom wall of the notch 71, a sliding column 76 is slidably connected in the chute 75, a limiting spring 77 is arranged in the chute 75, and the limiting spring 77 pushes the sliding column 76 to slide towards the direction of the glass to limit the inclined plate 74. When the coated glass is conveyed along the roller 3, its side contacts the inclined plate 74 and squeezes the carriage 73 to slide out along the slide rail 72.

[0040] Ring sleeves 78 with openings at the bottom are fixedly arranged at both ends of the main water pipe 5, and the two ring sleeves 78 are arranged in an opposite and staggered manner along the left and right sides of the main water pipe 5.

[0041] A sub-water pipe 79 with both ends closed is slidably connected in the ring sleeve 78, and a number of spray nozzles 6 are also arranged at the bottom of the sub-water pipe 79. The carriage 73 is fixedly connected to the sub-water pipe 79 through a connecting rod 710.

[0042] An outlet 711 communicating with the main water pipe 5 is opened inside the ring sleeve 78, a number of inlets 712 matching the outlet 711 are opened on the side surface of the sub-water pipe 79, and the number of inlets 712 corresponds to the number of spray nozzles 6 on the sub-water pipe 79 one by one. During the outward sliding of the carriage 73, the sub-water pipe 79 slides out synchronously with the carriage 73. The width of the glass corresponds to the moving amount of the sub-water pipe 79, and different inlets 712 are aligned with the outlet 711. The water in the main water pipe 5 then enters the sub-water pipe 79 along the inlets 712 and is then sprayed out along the corresponding spray nozzles 6.

[0043] Inside the auxiliary water pipe 79 and fixedly arranged between two adjacent nozzles 6 is an annular seat 713. An annular seat 713 is also fixedly arranged inside the water inlet 712. The surface of the annular seat 713 is provided with a groove 714. A one-way sealing cover 715 that can be turned in one direction is rotatably connected in the groove 714. The water in the auxiliary water pipe 79 can push open the upper-level one-way sealing cover 715, so that the upper-level nozzle 6 sliding over the ring sleeve 78 discharges water synchronously, but cannot push open the lower-level one-way sealing cover 715, nor can it push open the one-way sealing cover 715 on the water inlet 712 in the reverse direction.

[0044] A water curtain adjusting assembly 716 is arranged in the nozzle 6.

[0045] In this embodiment, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 11 shown, the water curtain adjusting assembly 716 includes a hollow valve head 7161 fixedly installed in the nozzle 6. The bottom of the hollow valve head 7161 is fixedly provided with a fan shell 7162. The inside of the fan shell 7162 is provided with a fan groove 7163. The bottom of the fan groove 7163 communicates with the outside. The top of the fan shell 7162 is provided with an inner hole 7164, and the inner hole 7164 communicates the fan groove 7163 with the hollow valve head 7161.

[0046] Two fan plates 7165 are slidably connected in the fan groove 7163. The opposite sides of the surfaces of the two fan plates 7165 are fixedly connected with matching sealing plates 7166. The area between the two sealing plates 7166 and the two fan plates 7165 is set as a spray hole 7167. The water in the nozzle 6 is injected into the hollow valve head 7161 and sprays out along the inner hole 7164 into the spray hole 7167.

[0047] A slide plate 7168 is slidably connected inside the hollow valve head 7161. A top spring 7169 is arranged inside the hollow valve head 7161. The top spring 7169 pushes the slide plate 7168 to move upward. The bottom of the slide plate 7168 is fixedly provided with a sleeve 71610 with internal threads.

[0048] The upper side of the inner hole 7164 is rotatably connected with a rotating shaft 71611 with threads on the upper side through a bracket. The upper side shaft body of the rotating shaft 71611 is assembled in the sleeve 71610 through threads.

[0049] The bottom end of the rotating shaft 71611 is fixedly connected with a gear 71612. The side surface of the fan plate 7165 is provided with fan-shaped distributed tooth grooves 71613 meshing with the gear 71612. Increasing the water pressure can push the sliding plate 7168 to compress the top spring 7169 and move downward, and make the sleeve 71610 move downward to drive the rotating shaft 71611 to rotate. The rotating gear 71612 then pushes the two fan plates 7165 to slide away from each other along the tooth grooves 71613. At this time, the two sealing plates 7166 move relatively away from each other, increasing the spraying width of the spray holes 7167.

[0050] A speed regulating component 71614 for controlling the downward movement speed of the sliding plate 7168 is arranged on the hollow valve head 7161.

[0051] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 11 shown, the speed regulating component 71614 includes a micro electric cylinder 716141 fixedly installed on the side surface of the hollow valve head 7161. And a sleeve 716142 is fixedly connected to the side surface of the hollow valve head 7161. A gas plug 716143 is slidably connected in the sleeve 716142. The telescopic rod of the micro electric cylinder 716141 is fixedly connected with the gas plug 716143.

[0052] An airbag 716144 is fixedly arranged inside the hollow valve head 7161, and the airbag 716144 is located below the sliding plate 7168. An air hole 716145 communicating the airbag 716144 with the sleeve 716142 is opened on the hollow valve head 7161. Starting the electric cylinder drives the gas plug 716143 to move downward. The gas plug 716143 injects gas into the airbag 716144 along the sleeve 716142, so that the gas in the airbag 716144 is compressed. At this time, the hardness of the airbag 716144 increases, and the downward movement speed of the sliding plate 7168 pressed by the airbag 716144 slows down, that is, the adjustment speed of the water curtain width of the spray holes 7167 becomes slower.

[0053] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 11 shown, a hoop is arranged on the suspension 4. The main water pipe 5 is fixed by the hoop. After opening the hoop, the main water pipe 5 can be removed from the suspension 4, which is convenient for the user to carry out maintenance.

[0054] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 11As shown, the connecting rod 710 is fixed to the auxiliary water pipe 79 by bolts. After removing the bolts, the auxiliary water pipe 79 is separated from the connecting rod 710 and the side rail 2, and the auxiliary water pipe 79 can be removed from the equipment main body together with the main water pipe 5.

[0055] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 11 shown, a tapered edge is fixedly provided at the bottom edge of the fan plate 7165 on the side opposite to the spray hole 7167, and the gap between the tapered edges is smaller than the gap of the spray hole 7167 of the fan plate 7165, so that the water in the spray hole 7167 is pressurized when it sprays out between the tapered edges.

[0056] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 11 shown, the inside of the nozzle 6 is provided as a threaded interface, and the hollow valve head 7161 is screwed into the threaded interface. Rotating the hollow valve head 7161 can quickly disassemble and assemble it from the main water pipe 5 and the auxiliary water pipe 79, so that the user can perform maintenance and replacement.

[0057] A method for using a cleaning device for processing coated glass includes the following steps: S1. Place the coated glass on the roller 3, and the rotating roller 3 conveys the coated glass from left to right. During this process, water is conveyed into the main water pipe 5 by an external water pump and sprayed downward along the nozzle 6 to wash the coated glass.

[0058] S2. When the coated glass is conveyed along the roller 3, its side contacts the inclined plate 74 and squeezes the carriage 73 to slide outward along the slide rail 72. During this process, the auxiliary water pipe 79 slides outward synchronously with the carriage 73. The width of the glass corresponds to the movement amount of the auxiliary water pipe 79, and the water inlets 712 at different positions are aligned with the water outlets 711. The water in the main water pipe 5 then enters the auxiliary water pipe 79 along the water inlets 712 and is then sprayed out along the corresponding nozzles 6. Moreover, the water in the auxiliary water pipe 79 can push open the upper-stage one-way sealing cover 715, so that the upper-stage nozzles 6 passing through the ring sleeve 78 synchronously discharge water, while the lower-stage one-way sealing cover 715 cannot be pushed open.

[0059] S3. The water in the nozzle 6 is injected into the hollow valve head 7161 and enters the spray hole 7167 through the inner hole 7164 and sprays out. During this process, increasing the water pressure can push the sliding plate 7168 to compress the top spring 7169 and move downward, and make the sleeve 71610 move downward to push the rotating shaft 71611 to rotate. The following rotating gear 71612 then pushes the two fan plates 7165 to slide away from each other along the tooth grooves 71613. At this time, the two sealing plates 7166 move relatively away from each other, increasing the spraying width of the spray hole 7167.

[0060] S4. When the skateboard 7168 moves downward, the electric cylinder is activated to drive the air plug 716143 to move downward. The air plug 716143 injects air into the airbag 716144 along the sleeve 716142, causing the gas in the airbag 716144 to be compressed. At this time, the hardness of the airbag 716144 increases, and the downward movement speed of the skateboard 7168 pressing the airbag 716144 slows down, that is, the adjustment speed of the water curtain width of the spray hole 7167 becomes slower.
