Description

Technical Field

[0001] This invention relates to the field of coal mine truck painting technology, specifically to an auxiliary device for a digital painting depth camera. Background Technology

[0002] Coal mine railway freight cars operate in harsh environments characterized by high abrasion and corrosion. The coal they transport is inherently abrasive, and the frequent mechanical collisions during loading and unloading, coupled with exposure to sunlight and rain, coal dust, winter de-icing agents, and corrosive media such as sulfides and moisture contained in the coal, make the steel structure of the cars highly susceptible to rust and paint peeling. Therefore, implementing standardized and effective paint protection for coal mine railway freight cars is crucial. The core objective is to construct a long-lasting anti-corrosion coating system, isolate corrosive media, slow down the rate of steel corrosion, significantly extend the overhaul cycle and service life of the vehicles, ensure transportation safety and efficiency, and simultaneously improve the vehicles' appearance.

[0003] Currently, large coal mining enterprises or railway vehicle depots generally have dedicated freight car maintenance and painting lines or areas. A typical painting process mainly includes: first, thorough pretreatment of the car body surface, including high-pressure water or chemical cleaning to remove oil, old paint, and coal sludge. A key step is sandblasting or shot blasting to remove rust, achieving the required metal cleanliness and roughness. Subsequently, in a clean and dry environment, air spraying or airless spraying technology is used to apply primer, intermediate coat, and topcoat in layers. The primer is usually a strong-adhesion, rust-resistant epoxy zinc-rich primer or epoxy zinc phosphate primer; the topcoat often uses aliphatic polyurethane paint or modified epoxy paint with good weather resistance and abrasion resistance. Construction emphasizes environmental temperature and humidity control, uniform paint film thickness, and interlayer time management to ensure the overall protective performance of the coating system. Some advanced production lines have introduced automated or semi-automated painting equipment to improve efficiency and consistency.

[0004] Existing digital painting technologies typically model different types of trucks before painting them. When painting the same type of truck later, the stored model data can be used to achieve higher precision. Depth cameras are essential in the digital painting process. However, when painting the exterior of a truck, reflected paint may adhere to the depth camera's lens. Due to the small space in the painting booth, it is difficult to clean the paint manually during operation. This can cause significant deviations in the depth camera's image modeling, affecting the accuracy of the modeling. Summary of the Invention

[0005] In view of this, the technical problem to be solved by the present invention is to provide an auxiliary device for a digital spraying depth camera to solve the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an auxiliary device for a digital spraying depth camera, comprising a mounting housing, a depth camera body and a rear cover mounted within the mounting housing, and further comprising:

[0007] A cleaning mechanism is installed in front of the camera on the depth camera body. The movement of the cleaning mechanism prevents the rebounded paint from adhering to the camera.

[0008] A scraping mechanism is located inside the mounting housing, behind the depth camera body, and is used to clean the paint adhering to the cleaning mechanism to enhance the cleaning effect of the cleaning mechanism.

[0009] A drive mechanism, located inside the mounting housing, is used to drive the cleaning mechanism and the scraping mechanism.

[0010] The cleaning mechanism includes a mounting base, and several mounting bases are provided. A rotating roller is rotatably mounted on the mounting base, and a transparent film is sleeved on the rotating roller. The rotating roller on one of the mounting bases is connected to a drive mechanism.

[0011] Preferably, the scraping mechanism includes a fixing plate, which is mounted on the top plate of the mounting housing. A scraping component is rotatably mounted on the fixing plate. A storage box is provided on the side of the scraping component away from the depth camera body. The storage box is fixedly mounted on the top plate of the mounting housing. The storage box and the scraping component are connected by a connector.

[0012] Preferably, the scraping component includes a scraping plate with an inner cavity. A rotating shaft is fixedly installed on the side wall of the scraping plate, and a return spring is sleeved on the rotating shaft. One end of the return spring is fixedly connected to the scraping plate, and the other end is fixedly connected to a fixed plate.

[0013] Preferably, the connector includes a fixed base on which a connecting rod is hinged.

[0014] Preferably, the storage box has a storage cavity, a push plate is slidably installed in the storage cavity, a connecting block is fixedly installed on the push plate, the connecting block is hinged to the connecting rod, a feed pipe is fixedly installed on the top of the storage box, and several transport pipes are fixedly installed on the storage box, with the other end of the transport pipes communicating with the inner cavity of the scraper.

[0015] Preferably, a cleaning sponge is fixedly installed at one end of the scraper near the inner cavity.

[0016] Preferably, the driving mechanism includes a drive motor, which is fixedly mounted on a mounting base. The output end of the drive motor passes through the side wall of the mounting base and is fixedly connected to a rotating roller. A connecting rod is fixedly mounted on the side of the rotating roller away from the drive motor, and the connecting rod is fixedly connected to a rotating roller on another mounting base.

[0017] Preferably, a drive wheel is rotatably mounted on the outer wall of the mounting base, and a driven wheel is rotatably mounted on the fixed plate. The driven wheel and the drive wheel are connected by a belt drive. A striking roller is fixedly mounted on the driven wheel, and several striking plates are evenly arranged on the striking roller.

[0018] Preferably, the mounting bases in this device are provided in eight groups of four, with two groups positioned at the camera positions on the depth camera body.

[0019] Preferably, the transparent film can be a high-transparency PET-based optical film.

[0020] Compared with the prior art, the present invention provides an auxiliary device for a digital spraying depth camera, which has the following beneficial effects:

[0021] 1. By setting up a cleaning mechanism, this invention can block the reflection path of the spray paint when it is reflected in the spray painting workshop, reduce the coverage of the depth camera by the spray paint, and improve the accuracy of depth camera shooting and modeling.

[0022] 2. By setting up a scraping mechanism, the transparent film of the cleaning mechanism can be cleaned of the spray paint when it adheres to the film, which will affect the shooting of the depth camera. The scraping mechanism can clean the spray paint on the transparent film, extend the cleaning cycle of the transparent film, and improve work efficiency.

[0023] 3. By setting a tapping plate circumferentially on the tapping roller, the present invention can periodically squeeze the scraper against the transparent film, thereby periodically cleaning the transparent film. At the same time, the reset spring set on the tapping plate will cause the scraper to vibrate when it resets, which can shake off the cleaned paint, so that the scraper can achieve a self-cleaning effect.

[0024] 4. By setting up a storage box, the present invention allows the addition of a corresponding cleaning solution, such as turpentine or water, to the storage box. While scraping off the coating on the transparent film, the cleaning solution can be used to make the cleaning effect more significant and improve the accuracy of depth camera shooting and modeling.

[0038] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, some features described in the examples may be combined in other examples.

[0039] like Figures 1 to 8As shown, this embodiment of the invention provides an auxiliary device for a digital spraying depth camera, including a mounting housing 1, a depth camera body 2 mounted inside the mounting housing 1, and a rear cover 3, and further including:

[0040] The cleaning mechanism 4 is located in front of the camera on the depth camera body 2. The movement of the cleaning mechanism 4 prevents the rebounded paint from adhering to the camera.

[0041] The scraping mechanism 5 is located inside the mounting housing 1 and behind the depth camera body 2. It is used to clean the paint adhering to the cleaning mechanism 4 to enhance the cleaning effect of the cleaning mechanism 4.

[0042] The drive mechanism 6 is located inside the mounting housing 1 and is used to drive the cleaning mechanism 4 and the scraping mechanism 5.

[0043] The cleaning mechanism 4 includes a mounting base 41, which has several mounting bases. A rotating roller 42 is rotatably mounted on the mounting base 41, and a transparent film 43 is fitted on the rotating roller 42. The rotating roller 42 on one of the mounting bases 41 is connected to the drive mechanism 6.

[0044] The working principle and beneficial effects of the above technical solution are as follows: When using a depth camera, the depth camera body 2 is installed inside the mounting housing 1, and then the mounting housing 1 is installed in a position that facilitates scanning. When the truck is being painted, when the paint sprayed from the nozzle comes into contact with the truck, most of the paint will adhere to the truck, and a small portion of the paint will bounce back. The bounced paint will be intercepted by the cleaning mechanism 4 and will adhere to the transparent film 43, thus preventing the paint from directly contacting the lens of the depth camera, which would not only be difficult to clean but would also cause corrosion damage to the lens.

[0045] In one embodiment: the scraping mechanism 5 includes a fixing plate 51, which is mounted on the top plate of the mounting housing 1. A scraping component 52 is rotatably mounted on the fixing plate 51. A storage box 53 is provided on the side of the scraping component 52 away from the depth camera body 2. The storage box 53 is fixedly mounted on the top plate of the mounting housing 1. The storage box 53 and the scraping component 52 are connected by a connector 54.

[0046] The working principle and beneficial effects of the above technical solution are as follows: when a certain amount of spray paint adheres to the transparent film 43 of the cleaning mechanism 4, the scraper 52 will rotate under the drive of the drive mechanism 6, so that the scraper 52 can approach the transparent film 43. When the scraper 52 contacts the transparent film 43 and the rotating roller 42 at the transparent film 43, the spray paint on the transparent film 43 can be cleaned.

[0047] In one embodiment: the scraping member 52 includes a scraping plate 521, an inner cavity 522 is provided in the scraping plate 521, a rotating shaft 523 is fixedly installed on the side wall of the scraping plate 521, a return spring 524 is sleeved on the rotating shaft 523, one end of the return spring 524 is fixedly connected to the scraping plate 521, and the other end is fixedly connected to the fixing plate 51.

[0048] The working principle and beneficial effects of the above technical solution are as follows: When the scraping plate 521 rotates, after the external force is removed, the scraping plate 521 will be reset under the reset action of the reset spring 524. At the same time as the reset, the scraping plate 521 will vibrate to a certain extent. The vibration can shake off the spray paint cleaned off the scraping plate 521, so that the subsequent scraping effect is better.

[0049] In one embodiment, the connector 54 includes a base 541 on which a connecting rod 542 is hinged.

[0050] The working principle and beneficial effects of the above technical solution are as follows: when the scraping plate 521 rotates, it will drive the connecting piece 54 to move. That is, while the fixed seat 541 moves with the scraping plate 521, the connecting rod 542 will rotate on the fixed seat 541.

[0051] In one embodiment: a storage cavity 531 is provided inside the storage box 53, a push plate 532 is slidably installed inside the storage cavity 531, a connecting block 533 is fixedly installed on the push plate 532, the connecting block 533 is hinged to the connecting rod 542, a feed pipe 534 is fixedly installed on the top of the storage box 53, and a plurality of transport pipes 55 are fixedly installed on the storage box 53, the other end of the transport pipes 55 is connected to the inner cavity 522 of the scraper 52.

[0052] The working principle and beneficial effects of the above technical solution are as follows: When the connecting rod 542 moves, it will drive the connecting block 533 to move along the direction of the storage cavity 531, and then drive the push plate 532 to move along the direction of the storage cavity 531. The cleaning fluid in the storage box 53 can be transported to the inner cavity 522 of the scraper 52 through the transport pipe 55. A screw cap can be set on the feed pipe 534. When the cleaning fluid needs to be added, the screw cap can be opened to add the material. Furthermore, a one-way valve can be set on both the feed pipe 534 and the transport pipe 55, and a liquid pump can be connected to the feed pipe 534 to ensure the one-way flow of the cleaning fluid. Furthermore, the liquid pumped by the liquid pump can be preheated to improve the cleaning effect.

[0053] In one embodiment, a cleaning sponge 525 is fixedly installed at one end of the scraper 521 near the inner cavity 522.

[0054] The working principle and beneficial effects of the above technical solution are as follows: the cleaning fluid in the inner cavity 522 of the scraper 521 will wet the cleaning sponge 525. On the one hand, it can prevent the cleaning fluid from dripping onto the depth camera and damaging the camera. On the other hand, the cleaning sponge 525 can also increase the contact area between the cleaning fluid and the transparent film 43, resulting in a better cleaning effect.

[0055] In one embodiment, the drive mechanism 6 includes a drive motor 61, which is fixedly mounted on a mounting base 41. The output end of the drive motor 61 passes through the side wall of the mounting base 41 and is fixedly connected to a rotating roller 42. A connecting rod 62 is fixedly mounted on the side of the rotating roller 42 away from the drive motor 61, and the connecting rod 62 is fixedly connected to a rotating roller 42 on another mounting base 41.

[0056] The working principle and beneficial effects of the above technical solution are as follows: when the drive motor 61 is started, the rotating roller 42 will rotate, thereby causing the transparent film 43 to move slowly. At the same time, when the rotating roller 42 rotates, it will drive the connecting rod 62 to rotate, which will enable another set of cleaning mechanisms 4 to perform cleaning.

[0057] In one embodiment: a drive wheel 57 is rotatably mounted on the outer wall of the mounting base 41, a driven wheel 56 is rotatably mounted on the fixed plate 51, the driven wheel 56 and the drive wheel 57 are connected by a belt 58, a striking roller 59 is fixedly mounted on the driven wheel 56, and a plurality of striking plates 591 are evenly arranged on the striking roller 59.

[0058] The working principle and beneficial effects of the above technical solution are as follows: the drive wheel 57 rotates under the drive of the rotating roller 42, which drives the belt 58 to move, thereby driving the driven wheel 56 to rotate, which in turn drives the striking roller 59 to rotate. The striking plates 591, which are evenly arranged on the striking roller 59, can periodically squeeze and scrape the scraping plate 521 for periodic cleaning.

[0059] In one embodiment, there are eight mounting bases 41 in this device, and four are arranged in groups of two, with the two groups positioned at the camera positions on the depth camera body 2.

[0060] The working principle and beneficial effects of the above technical solution are as follows: the number of mounting bases 41 and rotating rollers 42 can be adjusted according to the actual situation. In this solution, a four-in-a-group setting method is adopted, which can guide the transparent film 43 at the four corners of the depth camera, minimize the contact between the transparent film 43 and the depth camera housing, and reduce wear. In actual use, it can also be adjusted according to the number of cameras and lighting lamps of the depth camera.

[0061] In one embodiment, the transparent film 43 may be a high-transparency PET-based optical film.

[0062] The working principle and beneficial effects of the above technical solution are as follows: the light transmittance of the high-transmittance PET-based optical film is not less than 92%, the haze is not higher than 0.5%, the surface hardness is moderate, and it takes into account both optical performance and scratch resistance. At the same time, the cost is low, making it cheaper and more practical in the environment in which this device is used.

[0063] Working principle and usage process: When using the depth camera, the depth camera body 2 is installed into the mounting housing 1, and then the mounting housing 1 is installed in a position that is easy to scan. When the truck is being painted, when the paint sprayed from the nozzle comes into contact with the truck, most of the paint will adhere to the truck, and a small portion of the paint will bounce off. The bounced paint will be intercepted by the cleaning mechanism 4 and will adhere to the transparent film 43, thus preventing the paint from directly contacting the lens of the depth camera, which would not only be difficult to clean but would also cause corrosion damage to the lens.

[0064] When the drive motor 61 is started, the rotating roller 42 will rotate, thereby causing the transparent film 43 to move slowly. At the same time, when the rotating roller 42 rotates, it will drive the connecting rod 62 to rotate, which will enable another set of cleaning mechanisms 4 to clean. The drive wheel 57 rotates under the drive of the rotating roller 42, which will drive the belt 58 to move, thereby driving the driven wheel 56 to rotate, which will drive the striking roller 59 to rotate. The striking plates 591, which are evenly arranged on the striking roller 59, can periodically squeeze the scraping plate 521 to perform periodic cleaning.

[0065] When the scraper plate 521 rotates, it drives the connecting piece 54 to move. That is, while the fixed seat 541 moves with the scraper plate 521, the connecting rod 542 rotates on the fixed seat 541. When the connecting rod 542 moves, it drives the connecting block 533 to move along the direction of the storage cavity 531, and then drives the push plate 532 to move along the direction of the storage cavity 531. The cleaning fluid in the storage tank 53 can be transported to the inner cavity 522 of the scraper 52 through the transport pipe 55. A screw cap can be installed on the feed pipe 534. When the cleaning fluid needs to be added, the screw cap can be opened to add the fluid. Furthermore, one-way valves can be installed on both the feed pipe 534 and the transport pipe 55, and a liquid pump can be connected to the feed pipe 534 to ensure the one-way flow of the cleaning fluid. Furthermore, the liquid pumped by the liquid pump can be preheated to improve the cleaning effect.

[0066] The cleaning fluid inside the cavity 522 of the scraper 521 will wet the cleaning sponge 525. On the one hand, this can prevent the cleaning fluid from dripping onto the depth camera and damaging it. On the other hand, the cleaning sponge 525 can also increase the contact area between the cleaning fluid and the transparent film 43, resulting in a better cleaning effect. The scraper 521 rotates. When the external force is removed, the scraper 521 will be reset by the reset action of the reset spring 524. At the same time as resetting, the scraper 521 will vibrate to a certain extent. The vibration can shake off the spray paint cleaned off the scraper 521, making the subsequent scraping effect better.

[0067] The embodiments of the present invention have been described above, but the embodiments are not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the embodiments described above, all of which are within the protection scope of the embodiments described above.
