Description

Technical Field

[0001] This application relates to the technical field of industrial film production, and in particular to a multi-stage stepped film production component and an automated production line film production system. Background Technology

[0002] Testing the physical and mechanical properties of building waterproofing materials and coatings is a crucial step in ensuring product quality. In this field, the membrane-forming process is a key step that directly impacts the accuracy and reliability of the test results. Traditional membrane-forming methods have been continuously optimized through long-term practice, providing fundamental support for the industry. However, with increasing market demands for testing precision and greater focus on experimental efficiency, the limitations of traditional membrane-forming technologies are gradually becoming apparent.

[0003] Currently, to prepare test films meeting standard thicknesses, laboratories typically employ manual methods. This involves mixing two-component or multi-component materials, pouring the mixture onto a flat plate, and then applying multiple coats using templates of varying thicknesses and a scraper. Specifically, researchers select templates of appropriate thicknesses based on standard requirements. For example, a 0.5mm or 0.8mm template might be used for the first coat, while a 1.2mm, 1.5mm, or 1.8mm template is used for the second coat, and so on, until the final dry film thickness of (1.5 ± 0.2) mm is achieved. Alternatively, foam strips can be used to control coating thickness, but this method relies heavily on manual operation.

[0004] However, the above methods have significant shortcomings. Rigid frames are prone to deformation during cleaning and replacement, leading to uneven sample thickness; flexible frames, due to insufficient rigidity, experience uneven stress during coating, similarly affecting the consistency of film thickness. Furthermore, the wide variety of frame materials and the lack of standardized procedures, coupled with varying operating techniques among different personnel, further exacerbate errors in film thickness. In addition, the use of foam adhesive strips is not only costly but also difficult to reuse, while rigid frames, although reusable, require time-consuming and labor-intensive cleaning, resulting in low economic efficiency. These factors collectively lead to significant deviations in experimental results, making it difficult to guarantee data consistency between different laboratories.

[0005] To address the limitations of traditional film-forming methods, this application proposes a multi-stage stepped film-forming component and an automated production line film-forming system. Utility Model Content

[0006] To address the limitations of traditional film-forming methods, this application provides a multi-stage stepped film-forming component and an automated production line film-forming system.

[0007] In a first aspect, this application provides a multi-stage stepped film-forming assembly, which adopts the following technical solution:

[0008] A multi-stage stepped film-forming assembly includes a template and a scraper. The template includes a substrate and a stepped groove disposed on the substrate. The stepped groove has at least two stages with a certain height difference between adjacent stages. The number of scrapers is equal to the number of stages of the stepped groove, and the width of any stage of the scraper matches the width of the stepped groove. Each scraper is provided with an anti-overflow baffle.

[0009] By adopting the above technical solution, and combining multi-level stepped grooves with matching scrapers, the template can be made into different films according to actual needs, thereby improving the adaptability of the template. By setting an anti-overflow baffle on the scraper, the slurry can be guided during scraping to prevent the slurry from overflowing the template.

[0010] Preferably, a discharge ramp is provided on one side of the substrate along the direction from the bottom to the top of the stepped groove.

[0011] By adopting the above technical solution, since a discharge ramp is provided on one side of the substrate along the bottom to top direction of the stepped groove, it is convenient to discharge excess slurry smoothly, avoid slurry accumulation at the edge of the template, reduce cleaning workload, and improve film making efficiency and ease of operation.

[0012] Preferably, there are two overflow baffles located at both ends of the scraper, the scraper is inclined towards the side closer to the overflow baffle, and the overflow baffle is inclined towards the side closer to the scraper.

[0013] By adopting the above technical solution, the anti-overflow baffles at both ends of the scraper can effectively prevent slurry from overflowing, reduce slurry waste, and keep the work surface clean. At the same time, the scraper is inclined towards the side closer to the anti-overflow baffle, which helps the slurry to be more evenly distributed in the stepped groove, improving the uniformity of film thickness. The anti-overflow baffle is inclined towards the side closer to the scraper, which can better guide the slurry to the designated area, thereby further improving the controllability and efficiency of the film-making process.

[0014] Preferably, the scraper is provided with a handle.

[0015] By adopting the above technical solution, the handle setting provides the operator with a stable gripping point, effectively preventing the problem of inconsistent film thickness caused by uneven hand force during the coating process, thereby improving the quality and uniformity of film production.

[0016] Preferably, one end of the scraper is provided with a housing, the housing including a housing part and a positioning part, the scraper including a scraping part and an adjusting part, the adjusting part being slidably disposed in the housing part, the positioning part of the housing being threadedly connected with a positioning bolt, the positioning bolt forming an abutting fit with the adjusting part, the housing being open downwards, the housing being provided with an arc-shaped limiting groove communicating with the opening of the housing, and the adjusting part forming an embedded sliding fit with the arc-shaped limiting groove.

[0017] By adopting the above technical solution, the adjustable length of the scraper is achieved. The scraping part of the scraper is used for the actual scraping operation, while the adjustment part is cleverly slidable within the storage part of the housing. By stretching the adjustment part within the storage part, the effective length of the scraping part can be flexibly adjusted, allowing a single scraper to adapt to the different width requirements of multi-level stepped grooves. The opening of the housing faces downward, and the adjustment part and the arc-shaped limiting groove within the storage part form an embedded sliding fit. This ensures that the bottom surface of the housing and the scraper are both in contact with the steps, and also prevents the scraper from falling out of the housing during the scraping process. In addition, the positioning part of the housing is threaded with a positioning bolt. When the scraper is adjusted to the appropriate length, the positioning bolt passes through the positioning part and abuts against the scraper, ensuring that the length of the scraper remains stable during the scraping process. This avoids uneven film thickness caused by length changes, thereby improving the accuracy and consistency of film formation.

[0018] Preferably, an elastic body is provided inside the storage part of the storage housing. One end of the elastic body is fixedly connected to the end of the storage part away from the positioning part, and the other end is fixedly connected to the adjustment part of the scraper.

[0019] By adopting the above technical solution, the elastomer is pulled along with the adjustment part of the scraper during the scraper length adjustment process. When the positioning bolt fixes the scraper at a suitable length, the elastomer can provide appropriate elastic support during the scraping process, thereby ensuring the uniformity of the slurry scraping. After the scraping is completed, the scraper can be automatically stored by unscrewing the positioning bolt, thereby reducing the operation steps in the storage process, improving work efficiency and reducing the manual burden.

[0020] Preferably, the spill prevention baffle includes a first baffle and a second baffle. The first baffle is fixedly connected to the positioning part of the housing, and the second baffle is fixedly connected to the scraping part of the scraper at one end away from the housing. The handle includes a first handle and a second handle. The first handle is fixedly connected to the positioning part, and the second handle is fixedly connected to the scraper at one end near the second baffle.

[0021] By adopting the above technical solution, the first baffle is fixed on the positioning part of the housing and is stable and immovable. The second baffle is set on the scraping part of the scraper at the end away from the housing, so that the second baffle can move flexibly with the adjustment of the scraper length. Thus, when the scraper is scraping any step, the first baffle and the second baffle can work together to ensure that both ends of the scraper have an anti-overflow effect, effectively avoiding the waste of slurry and keeping the operating environment clean. At the same time, the first handle is fixed on the positioning part, and the second handle moves flexibly with the adjustment of the scraper length, ensuring that when the scraper is scraping any step, the first handle and the second handle can be located at both ends of the scraping part of the scraper, so that the scraper is subjected to uniform force during the scraping process.

[0022] Secondly, this application provides an automated film-making production line system, which adopts the following technical solution:

[0023] An automated production line film-forming system including multi-stage stepped film-forming components includes a robot and a robotic arm mounted on the robot. The robotic arm is equipped with a clamping plate, which forms a clamping engagement with a handle on a scraper.

[0024] By adopting the above technical solution, using robots and robotic arms in conjunction with multi-stage stepped film-forming components, precise and efficient film-forming operations can be achieved in automated production lines. The clamping plates on the robotic arms and the handles on the scraper form a stable clamping fit, ensuring that the scraper remains stable during operation and avoiding errors caused by human operation.

[0025] Preferably, both the first handle and the second handle are T-shaped, and two corresponding snap-fit ​​grooves are provided on the clamp plate, with the first handle and the second handle fitting into the snap-fit ​​grooves.

[0026] By adopting the above technical solution, both the first and second handles are T-shaped and fit into the snap-fit ​​groove on the clamping plate, which further improves the reliability of the connection, prevents the scraper from shifting during the scraping process, and ensures that the scraper accurately fits the stepped groove of the template, thereby producing a coating with uniform thickness that meets the standard requirements. This solution not only improves the film-making efficiency, but also effectively reduces the problem of uneven thickness caused by manual operation.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The stepped groove template combined with the matching multi-stage scraper allows the template to produce different films according to actual needs, improving the practicality of the template. The stepped groove is equipped with a discharge ramp, which allows the waste generated during the scraping process to be discharged directly, improving the film making efficiency. The anti-overflow baffles at both ends of the scraper can guide the slurry in the template and prevent the slurry from overflowing.

[0029] 2. A storage housing is provided at one end of the scraper to store the scraper's adjustment part, so that the scraping part of the scraper that actually scrapes can be flexibly adjusted in length, thereby enabling a single scraper to adapt to the different width requirements of multi-level stepped grooves. An elastic body is provided in the storage housing and connected to the scraper's adjustment part, which can provide a certain elastic support during the scraping process and realize the automatic storage of the adjustment part.

[0030] 3. Using robots to replace manual labor for coating reduces the probability of errors and improves film-making efficiency. The handle is T-shaped and the clamping plate of the robotic arm is equipped with corresponding locking grooves. The handle and locking grooves form an embedded fit, making the connection more stable and preventing the scraper from shifting during the coating process. This ensures that the scraper is subjected to uniform force during the coating process and further improves the accuracy of film making. Attached Figure Description

[0038] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail.

[0039] Embodiment 1 of this application discloses a multi-level stepped film-forming assembly.

[0040] Reference Figure 1 A multi-stage stepped film-forming assembly includes a template 1 and a scraper 2. The template 1 is made of a rigid material and is selected from materials with an easy-to-release coating or polytetrafluoroethylene. The template 1 includes a rectangular substrate 11 and stepped grooves 12 disposed on the substrate 11. A discharge ramp 13 is provided on one side of the substrate 11 along the bottom to top direction of the stepped grooves 12, that is, the side with the discharge ramp 13 is the final direction of scraping. Vaseline or stone can also be used inside the stepped grooves 12. Wax and other release agents are used for demolding. The stepped groove 12 can be made into multiple steps such as two, three, and four steps according to the characteristics of existing market products. There is a certain range of height difference Δh between adjacent steps (e.g., Δh = 0.5mm to 0.8mm). The number of scrapers 2 is equal to the number of steps of the stepped groove 12. The width of each scraper 2 matches the width of the stepped groove 12 to adapt to different widths of the stepped groove 12. Both ends of the scraper 2 have anti-overflow baffles 3.

[0041] In practical use, films of different thicknesses can be made by filling the stepped grooves 12 with the slurry used for film making at different heights, thereby improving the adaptability of the template 1. The anti-overflow baffles 3 set at both ends of the scraper 2 guide the slurry during the scraping process, preventing the slurry from overflowing. In addition, excess slurry during the scraping process can be directly discharged through the discharge ramp 13, thereby improving the film making efficiency.

[0042] Reference Figure 1 The scraper 2 is tilted vertically at about 60-70 degrees to the side near the overflow baffle 3. Both overflow baffles 3 are tilted horizontally at about 70-80 degrees to the center of one side of the scraper 2. The handle 4 is located at the center of the scraper 2 and is a hexagonal prism, that is, six symmetrical contact surfaces 40 are formed on the handle 4.

[0043] In practical use, the scraper 2 has a certain tilt angle to be closer to the slurry, which helps to scrape the slurry evenly. The anti-overflow baffles 3 on both sides taper slightly inward, which can better guide the flow of the slurry and make the film formation more uniform. The handle 4 and the contact surface 40 provide the operator with a relatively stable point of force application, avoiding the problem of inconsistent film thickness caused by uneven force application during the scraping process.

[0044] The implementation principle of Embodiment 1 of this application is as follows: By setting a stepped groove 12 on the substrate 11 and matching it with a multi-stage scraper 2, the template 1 can produce different films according to actual needs, which improves the adaptability of the template 1. At the same time, a discharge ramp 13 is set on one side of the substrate 11, so that the excess material generated during the scraping process can be directly discharged from the discharge ramp 13, which further improves the scraping efficiency. Slightly inwardly converging anti-overflow baffles 3 are set at both ends of the scraper 2, which can guide the slurry in the template 1 and prevent the slurry from overflowing during the scraping process. The design of the scraper 2 tilting towards the anti-overflow baffle 3 makes the scraper 2 closer to the slurry, which helps to scrape the slurry evenly. Finally, a handle 4 is set on the scraper 2 and a contact surface 40 is set on the handle 4, which provides a relatively stable force point for the operator and avoids the problem of inconsistent film thickness caused by uneven force during the scraping process.

[0045] This application also discloses a multi-stage stepped film-forming assembly in embodiment two, which differs from embodiment one in that:

[0046] Reference Figure 2 and Figure 3 The scraper 2 has a housing 5 at one end. The housing 5 includes a housing part 51 and a positioning part 52. The width of the housing 5 does not exceed the width difference between adjacent steps. The housing part 51 is perpendicular to the positioning part 52. The scraper 2 includes a scraping part 21 and an adjustment part 22 located in the housing part 51. The housing 5 is set with an opening facing downward. The bottom surface of the housing 5 and the scraper 2 can be attached to any step horizontal surface of the stepped groove 12. The arc-shaped limiting groove 511 is set with a crescent-shaped cross section and is connected to the opening of the housing 5. The adjustment part 22 and the arc-shaped limiting groove 511 form an embedded sliding fit.

[0047] In practical use, the effective length of the scraping part 21 can be flexibly adjusted by the stretching adjustment part 22, so that both ends of the length direction of a single scraper 2 can adapt to the different steps of the multi-level stepped groove 12. At the same time, the adjustment part 22 and the arc-shaped limiting groove 511 in the storage part 51 form an embedded sliding fit, which can prevent the scraper 2 from falling out of the storage housing 5 during the scraping process.

[0048] Reference Figure 2 and Figure 4 The positioning bolt 521 is threaded onto the positioning part 52, and the positioning bolt 521 and the adjusting part 22 of the scraper 2 form an abutting fit. The elastic body 512 inside the housing 5 is a spring rope, and one end of the elastic body 512 is fixedly connected to the end of the housing 51 away from the positioning part 52, and the other end is fixedly connected to the adjusting part 22 of the scraper 2.

[0049] In practical use, when the scraper 2 is adjusted to a suitable length, the positioning bolt 521, which is threaded onto the positioning part 52, abuts against the scraper 2, ensuring that the length of the scraper 2 remains stable during the scraping process. When adjusting the length of the scraper 2, the elastic body 512 is also pulled along with the adjustment part 22 of the scraper 2, thereby providing appropriate elastic support during the scraping process and ensuring the uniformity of the slurry scraping. At the same time, after the scraping is completed, as long as the positioning bolt 521 on the positioning part 52 is unscrewed, the elastic body 512 in the storage part 51 will pull the scraper 2 to slide into the storage housing 5, thereby realizing the automatic storage of the scraper 2, thereby reducing the operation steps in the storage process. In other embodiments, the scraper 2 can also be manually pushed for storage adjustment.

[0050] Reference Figure 2 and Figure 3 The spill baffle 3 includes a first baffle 31 and a second baffle 32. The first baffle 31 is fixedly connected to the positioning part 52 of the housing 5, and the second baffle 32 is fixedly connected to the scraping part 21 of the scraper 2 at the end away from the housing 5. Both the first baffle 31 and the second baffle 32 are inclined inward at about 70-80 degrees. The handle 4 includes a first handle 41 and a second handle 42. The first handle 41 is also fixedly connected to the positioning part 52 of the housing 5, and the second handle 42 is fixedly connected to the scraper 2 at the end near the second baffle 32.

[0051] In actual use, the first baffle 31 and the first handle 41 are fixed on the positioning part 52 of the housing 5 and remain stationary, while the second baffle 32 and the second handle 42 move with the length change of the coating part 21 during the length adjustment of the scraper 2. This ensures that when the scraper 2 is adjusted to any length, the anti-overflow baffle 3 and the handle 4 can remain in fixed positions on both sides of the scraper 2, ensuring that the anti-overflow baffle 3 can guide the slurry at any step, and at the same time ensuring that the handle 4 is subjected to balanced force on both sides of the scraper 2, thereby avoiding the problem of uneven film thickness during the film making process.

[0052] The implementation principle of Embodiment 2 of this application is as follows: A storage housing 5 for accommodating the scraper 2 is provided using the space between adjacent steps of the stepped groove 12. The adjustment part 22 of the scraper 2 is housed within the storage part 51 of the storage housing 5. By stretching the adjustment part 22, the length of the scraping part 21 actually used for scraping can be flexibly adjusted. Simultaneously, the positioning bolt 521 threaded onto the positioning part 52 abuts against the adjustment part 22 of the scraper 2, fixing the position of the adjustment part 22 after the scraper 2 is adjusted to a suitable length. This allows a single scraper 2 to adapt to different width requirements of the multi-level stepped groove 12. The opening of the storage housing 5 faces downwards, allowing both the bottom surface of the storage housing 5 and the scraper 2 to conform to any step of the stepped groove 12's horizontal surface. The positioning groove 511 is connected to the opening of the housing 5, and the arc-shaped limiting groove 511 forms an embedded sliding fit with the adjustment part 22 of the scraper 2. This can prevent the scraper 2 from falling out of the housing 5 with the bottom opening during the scraping process. The elastic body 512 in the housing part 51 is fixedly connected to the housing part 51 and the adjustment part 22 respectively. When the adjustment part 22 is stretched, the elastic body 512 is pulled along with the adjustment part 22, thereby providing appropriate elastic support during the scraping process and ensuring the uniformity of the slurry scraping. After the scraping is completed, as long as the positioning bolt 521 on the positioning part 52 is unscrewed, the elastic body 512 in the housing part 51 will pull the scraper 2 to slide into the housing 5, thereby realizing the automatic storage of the scraper 2 and reducing the operation steps in the storage process.

[0053] The anti-overflow baffles 3 on the scraper 2 are divided into a first baffle 31 and a second baffle 32, and the handle 4 is divided into a first handle 41 and a second handle 42. The first baffle 31 and the first handle 41 are fixed to the positioning part 52 of the housing 5 and cannot be moved. The second baffle 32 and the second handle 42 are fixed to the scraping part 21 of the scraper 2 at the end away from the housing 5. When adjusting the length of the scraping part 21 of the scraper 2, the second baffle 32 and the second handle 42 move with the scraping part 21, thereby ensuring that the anti-overflow baffles 3 on both sides of the scraper 2 can guide the slurry at any step during the scraping process, and at the same time ensure that the handle 4 is subjected to balanced force on both sides of the scraper 2, so as to avoid the problem of uneven film thickness during the film making process.

[0054] Embodiment 3 of this application also discloses an automated production line film-forming system including the above-mentioned multi-stage stepped film-forming components, which differs from Embodiments 1 and 2 in that:

[0055] Reference Figure 5 An automated film-making production line system includes a robot 6 and a robotic arm 61 mounted on the robot 6. The clamping plate 62 on the robotic arm 61 can form a clamping engagement with the handle 4 of the scraper 2.

[0056] When the clamping plate 62 on the robotic arm 61 is engaged with the first embodiment of the application, the robot 6 replaces the manual to perform the scraping work. The clamping plate 62 on the robotic arm 61 forms a clamping engagement with the hexagonal prism handle 4 in the first embodiment. The abutting surface 40 on the handle 4 abuts against the clamping plate 62, making the clamping engagement more stable.

[0057] Reference Figure 5 and Figure 6 When the clamping plate 62 on the robotic arm 61 is engaged with the second embodiment of the application, the first handle 41 and the second handle 42 are both arranged in a "T" shape, and there are two corresponding snap-fit ​​grooves 621 at both ends of the clamping plate 62. The first handle 41 and the second handle 42 are respectively engaged with the snap-fit ​​grooves 621.

[0058] In actual use, the two snap-fit ​​grooves 621 on the clamp plate 62 are fitted into the first handle 41 and the second handle 42, which are T-shaped in the second embodiment, further improving the reliability of the connection and enabling the scraper 2 to accurately fit the stepped groove 12 during the scraping process.

[0059] The implementation principle of Embodiment 3 of this application is as follows: The robotic arm 61 of the robot 6 replaces the manual labor for the coating work. The automated operation reduces human intervention, thereby reducing the probability of error and improving the film-making efficiency. The clamping plate 62 on the robotic arm 61 forms a clamping fit with the hexagonal prism handle 4 in Embodiment 1. The contact surface 40 of the handle 4 makes the clamping fit more stable. In Embodiment 2, the first handle 41 and the second handle 42 are both set in a "T" shape. The clamping plate 62 of the robotic arm 61 also has two corresponding snap-fit ​​grooves 621. The snap-fit ​​grooves 621 form an embedded fit with the first handle 41 and the second handle 42, which prevents the scraper 2 from deviating during the coating process, thereby ensuring that the scraper 2 is subjected to uniform force during the coating process and further improving the accuracy of film making.

[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
