Description

Technical Field

[0001] The present invention relates to the technical field of glass cleaning, in particular to a novel automatic cleaning device for clean thick glass. Background Art

[0002] In today's high-end optical manufacturing industry, the importance of specialty glass, as a core base material for optical equipment, is self-evident. This is especially true in large optical equipment, where the glass used is often thick and heavy. The processing of this type of specialty glass requires multiple precision steps, including blank manufacturing, polishing, cleaning, testing, and sealing and packaging. The final product must not only meet stringent standards for highly consistent dimensions but also achieve the ultimate requirements of high surface cleanliness and no damage. Against this backdrop, the importance of the cleaning process, as a key link in ensuring product quality, has become increasingly prominent. However, traditional clean glass cleaning processes still rely heavily on manual labor. Workers are required to wear dust-free suits in a clean room, holding dust-free cloths and spray bottles to clean the glass. This manual wiping method has many obvious disadvantages. On the one hand, the cleaning efficiency of workers wearing dust-free suits is low, which is especially obvious when cleaning thick glass. On the other hand, since different workers may have different operating techniques, strength and cleaning levels, it is difficult to ensure the consistency of cleaning quality, which will affect the subsequent processing steps and the overall quality of the product. In addition, the cleaned workpieces usually need to be air-dried in the air duct, but the static air duct outlet is easily affected by the air flow disturbance at the bend of the duct, causing the end wind pressure to drop by 15%-20%, reducing the drying efficiency.

[0003] At present, the cleaning of thick and high-cleanliness glass generally has problems such as low automation and poor coordination of various cleaning links. The connection between the feeding, cleaning, drying and other processes of the equipment is not smooth enough, resulting in low overall cleaning efficiency and difficulty in meeting the growing production needs.

[0007] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0008] 1. This equipment integrates four systems: feeding, spraying, wiping, and air drying, creating a fully automated cleaning system. The reciprocating wiping trajectory driven by the robotic arm and the synchronous operation of the spray head form a dynamic cleaning interface. Compared with traditional step-by-step cleaning processes, the overall efficiency is improved by over 40%, achieving a highly efficient connection of the cleaning process.

[0009] 2. The front end of the robotic arm is integrated with a six-dimensional torque sensor, a spring buffer assembly, and a front-end wiping soft-installation assembly: the spring buffer assembly has the functions of both shock absorption and constant pressure output. Combined with the real-time pressure monitoring of the torque sensor, it can accurately control the contact force between the wiping assembly and the workpiece to avoid surface damage; the wiping soft pad is made of TPE material. With its high flexibility, compressibility and surface self-lubricating properties, it can precisely fit the surface of the workpiece under the action of spring pressure to ensure the wiping effect. Two sets of nozzles are configured at the front end of the robotic arm, symmetrically aligned with the pressing surface of the wiping assembly and the workpiece. Through the coordinated adjustment of the water pump and the water tank return valve, the pure water spray pressure is precisely controlled to avoid water impact and damage to the workpiece. The dual robotic arms are distributed on both sides of the workpiece and can complete double-sided spraying simultaneously. The symmetrical layout of the nozzles ensures full coverage of the water flow and effectively dissolves residual particles, organic matter and metal ions.

[0010] 3. When the dust-free cloth on the surface of the TPE soft pad contacts the workpiece, the synchronously sprayed pure water can soften the surface pollutants and form a liquid boundary layer during the wiping process, which not only ensures the efficiency of pollutant removal but also avoids surface scratches caused by mechanical friction.

[0011] 4. After the workpiece that has been wiped with pure water spray enters the alcohol spray station, the upper nozzle sprays alcohol along the top edge of the workpiece. The spray pressure is adjusted by the alcohol water tank reflux valve to make the alcohol flow downward evenly along the surface at an appropriate flow rate; the lower nozzle replenishes alcohol along the center line of the workpiece to ensure full coverage of the lower part of the large surface and quickly remove surface moisture.

[0012] 5. The air drying mechanism utilizes a high-pressure vortex blower with primary and secondary filters to generate clean, dry air. The symmetrically arranged rotating duct assembly utilizes a motor-driven pulley system for angular deflection. Three rows of 1mm diameter chamfered holes on the duct expand the airflow coverage area to 40% while preventing high-pressure airflow from damaging the glass surface. The diffused jet airflow ensures simultaneous drying of alcohol from the workpiece surface. The rotary motion achieves uniform drying across different locations, improving drying efficiency and consistency. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In addition, “several” means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0026] The embodiment of the present invention discloses a vertical automatic cleaning device.

[0027] Example 1 Reference Figure 1 and Figure 2 The vertical automatic cleaning equipment includes a feeding mechanism 1, a spraying and wiping mechanism 2, an alcohol spraying component 3, an air drying mechanism 4, and a water tank component 5; The feeding mechanism 1 includes a first frame 38, a fourth frame 226, a linear motor 10, and a fixed tooling 9. The spray and wiping mechanism 2 includes a second frame 54, and the air-drying mechanism 4 includes a third frame 133. The first frame 38, the second frame 54, the third frame 133, and the fourth frame 226 are sequentially fitted together. The linear motor 10 is placed between the frames. The fixed tooling 9 is placed on the linear motor 10. The linear motor 10 can sequentially feed the workpiece 6 to be cleaned into the loading section, the spray and wiping section, the alcohol spraying section, the air-drying section, and the unloading section. In the present invention, the transmission component can be a linear motor 10 or a synchronous belt guide rail. The loading section is located on the first frame 38. A first limit switch 401 is provided on the left side of the first frame 38. The feeding mechanism 1 is provided with a water baffle. When the water baffle contacts the first limit switch 401, the feeding mechanism 1 stops moving and places the workpiece 6 to be cleaned on the bottom limit block 20 and the bottom support block 21. The four sets of side locking assemblies 13 tighten and secure the workpiece 6. Then, the linear motor 10 moves the secured workpiece 6 to the spray wiping section. The spray wiping section is located on the second frame 54, and the first manipulator assembly 11 and the second manipulator assembly 12 are respectively arranged on both sides of the second frame 54. The first manipulator 69 and the second manipulator 68 first drive the wiping spray head connection assembly 65 to spray along the upper edge of the workpiece to wet the entire large surface. After the spraying is completed, the first manipulator 69 and the second manipulator 68 come to the initial wiping position, and the front end wiping soft assembly 80 is pressed against the large surface of the glass to wipe. When wiping, the spray nozzle needs to spray water uniformly to wet the wiping surface. When the fixing tool 9 fixes both sides of the workpiece 6, space is left on both sides. The side pressure block 14 is smaller than the thickness of the glass. The front end wiping soft assembly 80 It is necessary to wipe from the right gap to the left gap of the large glass surface. After wiping is completed, the first manipulator 69 and the second manipulator 68 need to drop a certain height and repeat the wiping action until the entire large surface is wiped. During the initial spraying and wiping, the first manipulator 69 and the second manipulator 68 must ensure simultaneous and unidirectional movement. After the large surface is wiped, the wiping spray head connection assembly 65 is equipped with a double-claw cylinder 84, which can quickly replace the front-end wiping soft-installation component 80. The manipulator places the front-end wiping soft-installation component 80 on the front-end component placement table 98, and clamps another front-end wiping soft-installation component 80 on the front-end component placement table 98 to continue wiping the workpiece 6; The front-end wiping soft-installation assembly 80 includes a soft-installation clamping plate 85, a triangle plate 86, and a TPE soft pad 87. The TPE soft pad 87 is arranged on the triangle plate 86. A dust-free cloth is arranged on the TPE soft pad 87 for wiping. The TPE soft pad 87 is equipped with a dust-free cloth. After being wetted with pure water, it will not scratch the surface of the workpiece 6. Its elastic structure cooperates with the spring 89 to fit the surface of the workpiece 6 well. Even if the surface is slightly tilted, it can ensure constant fit. The pressure is evenly distributed during the wiping process. The composite dust-free cloth is used to wipe the surface of the TPE plate. The high adsorption and low particle shedding characteristics of the dust-free cloth can effectively remove dust, oil and organic residues on the surface of the workpiece 6. Reference Figure 4 and Figure 5Linear motor 10 is flanked by gutter 613, which has an outlet 614 below alcohol spray assembly 3. The gutter 613 bottom plates 620 on either side of outlet 614 are inclined. Ribs 622 are located on either side of gutter 613, with a water retaining plate 30 positioned between them to ensure that all spray wastewater flows into outlet 614. The lowest point of gutter 613 is higher than wastewater tank 265. The drainage system utilizes a gravity-guided water collection path design. The inclined bottom plates of gutter 613 create a height difference, ensuring that cleaning wastewater flows smoothly into wastewater tank 265, effectively reducing the risk of liquid stagnation. Wastewater tank 265 is equipped with a float switch 270, a pipe slipknot 275, and a wastewater valve 276. Its non-fixed mounting structure connects to the drainage pipeline via the pipe slipknot 275, allowing for flexible adaptation to wastewater treatment requirements in varying operating conditions. When the wastewater level triggers the float switch 270, the system automatically closes the wastewater valve 276. At this time, the pipe knot 275 can be unscrewed to quickly disassemble the float switch 270. After the wastewater treatment is completed, it can be restored to recycling.

[0028] Example 2 Reference Figure 1 、 Figure 7 and Figure 9 After the spraying and wiping is completed, the linear motor 10 drives the workpiece 6 into the third frame 133. The third frame 133 is provided with a pipe mounting plate 340. The alcohol spray assembly 3 includes a first alcohol upper nozzle 178, a second alcohol upper nozzle 175, a first alcohol lower nozzle 179, and a second alcohol lower nozzle 176. The nozzles are installed on the pipe mounting plate 340. The nozzles are symmetrically arranged on both sides of the linear motor 10. The linear motor first feeds the material to the initial alcohol spraying station, the first alcohol upper valve 185 and the second alcohol upper valve 183 are opened, and then the alcohol water pump 99 is started to supply liquid to the upper nozzle. The linear motor slowly feeds the material to the final alcohol spraying station, and then waits for a few seconds. The first alcohol lower valve 186 and the second alcohol lower valve 184 are opened, and the alcohol water pump 99 is started to supply liquid to the lower nozzle. The linear motor slowly feeds the material to the initial alcohol spraying station. After the alcohol spraying is completed, it is sent to the air drying station.

[0029] Example 3 Reference Figure 1 and Figure 3 The air drying mechanism 4 includes a third frame 133, a pure water pump 100, an alcohol water pump 99, a high-pressure vortex fan 192, a primary filter 138, a secondary filter 145, a first rotary air duct assembly 190, and a second rotary air duct assembly. Figure 3This is a schematic diagram of the first rotating air duct assembly 190. The high-pressure vortex fan 192 provides sufficient air volume for the first rotating air duct assembly 190. The primary filter 138 (removes large particles) and the secondary filter 145 (precision filtration) ensure that the air is clean and pollution-free (Note: in order to keep the drawings simple, the air ducts are not shown in the drawings). The first rotating air duct assembly 190 and the second rotating air duct assembly are symmetrically arranged. The main air inlet pipe 217 is connected to the secondary filter 145 through a pipe. The main air inlet pipe 217 supplies air to the four rotating air ducts 211. The top of the rotating air duct is provided with a bearing and a sealing ring, and the bottom is provided with a bearing and a driven bevel gear 215. The drive motor 219 drives the active bevel gear 206, thereby driving the driven bevel gear 215 to rotate. The four rotating air ducts 211 rotate in the same direction and speed. The frequency of the high-pressure vortex fan 192 is adjustable to prevent excessive wind speed from damaging the surface of the workpiece 6. The linear motor 10 delivers the workpiece to the center of the four rotating air ducts 211. The drive motor 219 drives the four rotating air ducts 211, slowly rotating them left and right. This concentrates the clean, dry airflow into sheets at high speed, rapidly sweeping across the surface of the workpiece 6 in a laminar flow pattern, evenly drying the surface of the workpiece 6. The rotating air ducts 211 ensure that the airflow trajectories of adjacent apertures form a 10%-30% overlap on the glass surface. The centrifugal force generated by the rotation creates a vortex ring effect at the aperture outlet. Compared to static air ducts, the effective range is increased by 40%-60% at the same air volume, improving drying efficiency and reducing energy consumption by 20%-35%. Compared with the transmission air knife spraying method, manual blowing can dry the workpiece 6 after spraying, but the manual blowing distance is difficult to control. The drying efficiency is low at a distance and there may be a risk of residual water stains. If it is too close, the wind speed will be too high and the surface of the workpiece 6 will be damaged. Therefore, this embodiment can ensure that the workpiece 6 is completely dry and the surface is not damaged after the entire process.

[0030] Example 4 refer to Figure 2 The unloading section is located in the fourth frame 226, and a second limit switch 402 is provided on the right side of the fourth frame 226. The feeding mechanism 1 is provided with a water baffle. After the water baffle contacts the second limit switch 402, the feeding mechanism 1 stops moving, and the side locking assembly 13 can be loosened to remove the workpiece 6.

[0031] Example 5 refer to Figure 6The triangular plate 86 in the front-end wiping soft furnishing component 80 is specifically a triangular structure with an angle of about 110° and a large rounded corner in the middle. The TPE soft pad 87 fits tightly on the triangular plate 86. When the TPE soft pad 87 contacts the workpiece, due to the clamping force, the TPE soft pad 87 will deform, thereby realizing a composite contact of surface contact and line contact. The spray universal nozzles 94 on the top of the front-end wiping soft furnishing component 80 are arranged symmetrically, and the spray universal nozzles are directed toward the rounded corner side of the upper part of the front-end wiping soft furnishing component 80 to ensure that the spray always wets the contact area of ​​the front-end wiping soft furnishing component 80 during wiping. Spraying pure water can instantly soften the pollutants and form a liquid boundary layer at the same time. Through the composite contact design of the front-end wiping soft furnishing component 80 (the synergistic effect of surface contact and line contact), the wiping efficiency of surface particulate pollutants can be significantly improved, and the friction during wiping can be reduced to avoid the influence of friction marks on the surface of the workpiece 6.

[0032] The above embodiment effectively solves the problems of extremely low manual efficiency and difficulty in ensuring consistent cleaning quality. The cleaning process is as follows: first spray with pure water, then wipe while spraying multiple times, then spray with alcohol, and then air dry. The purpose of spraying first is to prevent mechanical friction between solid particles on the surface and the wiping surface in a dry state, which could cause particles to embed into the material surface or cause microscopic scratches.

[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced therein.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment have also been appropriately combined to form other implementation methods that are easy for those skilled in the art to understand.
