Description

Technical Field

[0001] This utility model relates to the field of component painting technology, and in particular to a visual protective tooling for painting high-speed train components. Background Technology

[0002] In the manufacturing process of EMU components and related equipment, it is usually necessary to paint the surface of the workpieces. For this purpose, a dedicated paint booth or paint station needs to be set up for the painting operation, and the painting process needs to be monitored in real time to ensure the painting effect and intervene in a timely manner, thereby ensuring the painting quality of the workpiece surface.

[0003] Spray booths need to be sealed for extended periods during the painting process to prevent paint mist from overflowing and polluting the factory environment, and to avoid external dust entering the operating space and affecting the painting effect. To allow real-time observation of the workpiece painting process within the enclosed space, most spray booths and spray tables on the market typically have an observation window installed on one wall of the spray booth or on the protective cover of the spray table. Related protective measures are employed to ensure that the observation window is not contaminated by paint mist, thus affecting the observation effect.

[0004] For example, the patent with application number CN201520151707.2 discloses a self-cleaning visual window for a paint spraying booth. It mainly uses a wiper similar to a car windshield wiper to clean the inner glass of the window during the painting process, thereby ensuring a clear visual effect of the painting process.

[0005] However, when painting train components, the large size of the components results in a longer painting time and a higher concentration of paint mist, leading to frequent contamination of the inner glass of the viewing window. In such cases, scraping the glass with a scraper can actually spread the paint mist evenly, causing further blurring of vision in a short period. This interrupts the observation process, requiring multiple scrapings to ensure complete glass cleaning. Traditional paint protection fixtures cannot guarantee continuous observation and intervention during the painting process.

[0006] To address the above issues, a specialized paint protection fixture for painting large workpieces such as train components is needed. Utility Model Content

[0007] The present invention aims to solve the problem in the prior art that it is impossible to continuously monitor large workpieces such as train components during the painting process.

[0008] To solve the above-mentioned technical problems, this utility model provides a visual protection fixture for spray painting of high-speed train components, including a lower guide rail and an upper guide rail respectively installed on the inner wall of the spray booth. An observation port is opened in the middle of the wall between the lower guide rail and the upper guide rail, and a cleaning area is set on both sides of the observation port. A sliding glass window that can simultaneously cover the observation port and one side of the cleaning area is slidably provided between the lower guide rail and the upper guide rail.

[0009] The paint spraying visual protection fixture also includes at least two scraping and cleaning devices mounted on the wall for scraping sliding glass windows, and at least two roller blind devices with waterproof curtains mounted above the cleaning area.

[0010] In the above technical solution, the scraping cleaning device includes a driver, a rotating arm, and a scraping blade connected in sequence; the driver is installed on the wall below the lower guide rail and is used to drive the rotating arm and the scraping blade to rotate within the cleaning area; the scraping blade is in close contact with the glass surface of the sliding glass window and is made of rubber strip, hard bristle brush strip, or cloth strip.

[0011] Furthermore, in the above technical solution, a rubber strip is installed on the outer side of the window frame of the sliding glass window, that is, on the side closest to the wall, and the rubber strip is tightly fitted to the wall. In addition, a suction cup handle is installed on the outer glass surface of the sliding glass window.

[0012] Furthermore, in the above technical solution, several sprayers are vertically installed on the ends of the cleaning areas on both sides of the wall, facing the sliding glass windows. These are used to spray clean water or turpentine and other cleaning solutions onto the glass surfaces entering the cleaning area. Correspondingly, several drainage holes are opened at the bottom of the lower guide rail to drain the liquid that flows into the guide rail after being cleaned by the sprayers.

[0013] Furthermore, in the above technical solution, a liquid guide channel and a liquid collection device are installed close to the wall below the lower guide rail. The liquid guide channel slopes downward from both ends of the wall towards the middle and connects to the liquid collection device in the middle of the wall.

[0014] Furthermore, in the above technical solution, limit devices are installed at both ends of the upper guide rail. Preferably, the limit devices are equipped with distance sensors for sensing the position of the sliding glass window, and the distance sensors are connected to the controllers of the scraping cleaning device and the sprayer.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] Because the spray booth walls are equipped with sliding glass windows, cleaning devices, and roller shutters, the roller shutters inside the booth prevent half of the sliding glass windows from being contaminated by paint mist during spraying operations. Meanwhile, observers can monitor the spraying process in real time through the viewing window from outside the booth. When the viewing window becomes obstructed by paint mist, the observer can slide the glass window to move the contaminated window sash to the cleaning area for cleaning, while the uncontaminated window sash is moved back to the viewing window. This allows the observer to continue monitoring without waiting for the viewing window to be completely cleaned, ensuring continuous observation of the workpiece spraying process and facilitating timely responses and interventions.

[0024] The technical solution of this utility model will now be described with reference to the accompanying drawings. However, the described embodiments are only a part of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] It should be noted that in the description of this utility model, the terms "upper," "lower," "left," "right," etc., indicating directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings, such as... Figure 1 , 2 The image shown illustrates the installation of the visual protective tooling for painting train components of this utility model on the wall of a paint booth in normal working condition; the terms "inner" and "outer" used to describe the positional relationship are based on the attached diagram. Figure 3 The directions or positional relationships shown are as follows: "inside" refers to the direction from the observation port toward the paint booth, and "outside" refers to the opposite direction. This is merely for ease of description and is not intended to indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] like Figure 1-5 As shown, this utility model provides a visual protection fixture for spray painting of high-speed train components, including a lower guide rail 11 and an upper guide rail 12 respectively installed on the inner wall of the spray booth. An observation port 4 is opened in the middle of the wall between the lower guide rail 11 and the upper guide rail 12. Cleaning areas 41 are respectively set on both sides of the observation port 4. A sliding glass window 1 is slidably provided between the lower guide rail 11 and the upper guide rail 12, which can simultaneously cover the observation port 4 and one side of the cleaning area 41.

[0027] The paint spraying visual protection fixture also includes at least two scraping and cleaning devices 2 installed on the wall for scraping the sliding glass window 1, and at least two roller blind devices 3 with waterproof curtains 31 installed above the cleaning area 41.

[0028] Under normal circumstances, such as Figure 1 As shown, half of the sliding glass window 1 is located in the observation port 4, while the other half is located in the clean area 41 on one side. During the painting process on the train components, the roller shutter 3 of the clean area 41 lowers the waterproof curtain 31 to protect the glass in the clean area 41 from paint mist contamination in the paint booth. When the glass surface in the observation port 4 is contaminated with paint mist, affecting the observer's view, the observer can operate the sliding glass window 1 to push the contaminated glass surface into the clean area 41, simultaneously moving the uncontaminated window glass to the observation port 4, ensuring uninterrupted observation. At the same time, the scraping and cleaning device 2 is activated. The glass entering the clean area 41 is then cleaned by the scraping and cleaning device 2 under the cover of the waterproof curtain 31, and after cleaning, it awaits its next push to the observation port 4.

[0029] In the above technical solution, the scraping cleaning device 2 includes a driver 21, a rotating arm 22 and a scraping blade 23 connected in sequence; the scraping blade 23 is in close contact with the glass surface of the sliding glass window 1, and the driver 21 is installed on the wall below the lower guide rail 11 to drive the rotating arm 22 and the scraping blade 23 to rotate within the cleaning area 41.

[0030] Since the scraping cleaning device 2 is installed at the two ends of the observation port 4, its working angle is always facing the cleaning area 41, and the rotation angle covers the corresponding cleaning area 41. This ensures that no afterimages are generated within the observation port 4 due to the rotation of the scraping cleaning device 2, thus affecting the line of sight. Furthermore, by maintaining this working angle and rotation range, it ensures that the scraping blade 23 always stays on the glass surface of the sliding glass window 1 and will not fall off the glass surface due to the movement of the sliding glass window 1, thus interrupting the cleaning work.

[0031] To adapt to different painting scenarios, the scraper blade 23 can be made of materials such as rubber strips, stiff-bristled brush strips, or cloth strips. For example, in wet spraying scenarios, the paint mist adheres to the glass surface and still retains a certain degree of humidity. The scraper blade 23 can be made of rubber strips or cloth strips to easily wipe away the wet paint mist formed on the glass surface. In dry spraying processes, the paint mist on the glass surface dries and adheres quickly. Therefore, the scraper blade 23 can be made of stiff-bristled brush strips to easily brush away the dried paint mist, resulting in a better cleaning effect.

[0032] Furthermore, in the above technical solutions, such as Figure 3 As shown, a rubber strip 15 is installed around the entire perimeter of the window frame 14 of the sliding glass window 1, near the wall. The other side of the rubber strip 15 is flush with the wall to ensure the overall airtightness of the paint booth and prevent paint mist from leaking out through the gap between the sliding glass window 1 and the observation port 4, which could be inhaled by observers, affecting their health or causing air pollution in the factory area. A suction cup handle 13 is installed on the glass of the sliding glass window 1 corresponding to the observation port 4, allowing observers to easily operate the sliding glass window 1 to slide or move it horizontally.

[0033] Furthermore, in the above technical solution, several sprayers 7 are vertically installed on the ends of the cleaning areas 41 on both sides of the wall, facing the sliding glass window 1, for spraying clean water or turpentine and other cleaning solutions onto the glass surface entering the cleaning area 41. By spraying the cleaning solution, the cleaning effect on contaminated glass can be enhanced, quickly dissolving paint mist on the glass surface, thereby improving cleaning efficiency. Moreover, since a roller shutter device 3 is installed in the solution, when using cleaning solutions that can dissolve paint, such as turpentine, the waterproof curtain 31 can cover the cleaning area 41, preventing the sprayed liquid from drifting into the paint booth and overflowing towards the workpiece, thus affecting the workpiece's painting effect.

[0034] Correspondingly, since the liquid sprayed by the sprayer 7 will flow downwards through the glass surface into the lower guide rail 11, in order to prevent water accumulation in the lower guide rail 11, such as... Figure 4 As shown, several drainage holes 16 are opened on the bottom surface of the lower guide rail 11 to drain the liquid flowing into the lower guide rail 11, so as to avoid the liquid accumulating in the guide rail and affecting its use.

[0035] Furthermore, in the above technical solution, a liquid guide channel 6 and a liquid collection device 5 are installed close to the wall below the lower guide rail 11. The liquid guide channel 6 is installed inclined downwards from both ends of the wall towards the middle, and is connected to the liquid collection device 5 in the middle of the wall. The liquid flowing down from the spray in the cleaning area 41 flows into the liquid collection device 5 through the liquid guide channel 6. Preferably, the liquid collection device 5 can also be connected to the wastewater treatment device corresponding to the paint booth through a pipe, so that the liquid flowing down from the spray in the cleaning area 41 is finally discharged to the wastewater treatment device.

[0036] like Figure 5 As shown, furthermore, limit devices 17 are installed at both ends of the upper guide rail 12 to limit the lateral movement range of the sliding glass window 1 and prevent the sliding glass window 1 from being pushed too far and damaging the sprayers 7 on both sides of the cleaning area 41.

[0037] Preferably, a distance sensor 8 is also installed on the limiting device 17 to identify the position of the sliding glass window 1. The distance sensor 8 is connected to the controller of the scraping cleaning device 2 and the sprayer 7. When the sliding glass window 1 is pushed to the limiting device 17, the distance sensor 8 identifies the position of the sliding glass window 1 and sends a signal to the controller. The controller then drives the scraping cleaning device 2 or the sprayer 7 in the cleaning area 41 on the same side as the window sash to start cleaning the window sash. By setting the distance sensor 8, the overall automation level of the paint spraying visual protection fixture can be improved, avoiding the need for observers to simultaneously operate the scraping cleaning device 2 and the sprayer 7 to clean the glass during the observation process, thus ensuring that the observer's attention is focused during the observation process.

[0038] The implementation process of this utility model is as follows:

[0039] When the train parts enter the paint booth for painting, the waterproof curtains 31 of the two cleaning zones 41 are first lowered. Observers stand outside the paint booth and observe the interior through the observation port. During the painting process, if the glass surface in the observation zone 4 is contaminated by paint mist, obstructing the view, the observer operates the sliding glass window 1 to push the contaminated glass surface into the cleaning zone 41, while simultaneously moving the uncontaminated window to the observation port 4 for continued observation. The sliding glass window 1 entering the cleaning zone 41 triggers the distance sensor 8 to transmit a signal, activating the scraping and cleaning device 2 and sprayer 7 on the side where the sliding glass window 1 is located. At this time, the glass entering the cleaning zone 41 is cleaned and the paint mist on the glass surface is wiped away by the scraping and cleaning device 2 and sprayer 7 under the cover of the waterproof curtains 31. When the glass surface in the observation port 4 is contaminated by paint mist again, the above operation of the sliding glass window 1 is repeated, pushing the contaminated glass surface into the other cleaning zone 41, while the previously cleaned glass surface is pushed to the observation port 4. The liquid generated by the sprayer 7 during the process will flow down the glass surface, continue to flow down into the liquid guide channel 6 through the drain hole 16 on the lower guide rail 11, and finally flow into the liquid collection device 5 for unified removal.

[0040] This utility model has many application scenarios, including but not limited to the following described scenarios:

[0041] In the maintenance and painting of high-speed train components, painting is a crucial step. A high-quality paint finish protects the components from corrosion, extends their lifespan, and ultimately ensures the safe operation of the train. The paint booth equipped with the viewing window protective fixture of this invention provides a stable environmental condition for this process. Continuous observation allows for real-time intervention in the painting process, preventing damage or poor painting results caused by errors in painting equipment or paint, thereby improving paint quality and maintenance efficiency.

[0042] Furniture and Interior Decoration Painting Scenarios: For wood products and home furnishings, painting is one of the most important steps in determining the product's appearance and quality. The paint booth equipped with the viewing window protective fixture of this utility model allows for real-time, continuous observation, ensuring timely monitoring of the painting process by professionals. This enables timely guidance and intervention, ensuring the best possible color application to the product surface.

[0043] Painting in the manufacturing of large machinery and equipment: The external coating treatment of large equipment and machinery also needs to be carried out in a controlled and continuously monitored environment to ensure that the painting quality of the equipment meets the requirements of production use.
