Description

Technical Field

[0001] This utility model relates to the technical field of slot coating equipment, and in particular to an adaptive base and a scraping device. Background Technology

[0002] In slot coating, high-viscosity solutions are prone to lingering at the slot exit of the coating head, forming residues. If these residues are not removed promptly and effectively during production, they will accumulate rapidly and even solidify, directly causing quality defects such as uneven coating thickness, streaks, and trailing in the coating film, severely impacting product yield.

[0003] Currently, the industry mainly relies on manual wiping, solvent rinsing, or ultrasonic cleaning after disassembly for cleaning coating heads after shutdown. These traditional methods not only disrupt continuous production and reduce equipment uptime, but also have poor cleaning results due to heavy reliance on manual operation.

[0004] More importantly, existing cleaning device bases for mounting the scraper are typically rigid structures, lacking adaptive adjustment capabilities. In practical applications, the coating head itself may have manufacturing errors, thermal deformation, or minor deviations in its mounting posture, meaning its surface is not an ideal, perfectly flat plane. The scraper on the rigid base cannot conform to these subtle surface undulations and angular changes, resulting in either cleaning dead zones where residue is not completely removed, or excessive local pressure that wears down or even damages the expensive coating head lip surface.

[0005] It is evident that there are contradictions in the existing technology: on the one hand, high-viscosity coating requires online, real-time dynamic cleaning to ensure quality and efficiency; on the other hand, the existing cleaning device base, due to the limitations of its rigid structure, cannot intelligently adapt to the actual working state of the coating head, resulting in poor cleaning effect and safety hazards.

[0006] Therefore, this application proposes an adaptive base and a scraping device. Utility Model Content

[0007] The purpose of this invention is to provide an adaptive base and a scraping device. The adaptive base enables the scraping component to automatically adapt to the height changes or slight undulations of the object being cleaned (such as the coating head) in the Z-axis direction, and to maintain a constant and appropriate contact pressure. This solves the problem that traditional rigid cleaning devices may damage the coating head due to excessive pressure or fail to clean thoroughly due to insufficient pressure.

[0008] The objective of this utility model is achieved through the following technical solution:

[0009] On the one hand, this utility model provides an adaptive base, comprising:

[0010] Mounting plate, the mounting plate being used to mount the wiping assembly;

[0011] The Z-axis adaptive assembly includes one or more elastic structures, each of which includes a first support column and a spring. One end of the spring is connected to the first support column, and the other end of the spring is connected to the mounting plate. The assembly provides an elastic force that presses the squeegee against the object being cleaned, enabling the squeegee to move adaptively along the Z-axis to maintain a constant contact pressure with the object being cleaned.

[0012] The beneficial effect of the above solution is that, through the setting of the Z-axis adaptive component, the scraping component can automatically adapt to the height change or slight undulation of the object to be cleaned (such as the coating head) in the Z-axis direction, and always maintain a constant and appropriate contact pressure. This solves the problem that traditional rigid cleaning devices may damage the coating head due to excessive pressure or fail to clean thoroughly due to insufficient pressure. It ensures a stable and efficient cleaning effect without damaging the object to be cleaned.

[0013] Furthermore, the spring has a deformation range of 2 mm to 5 mm along the Z-axis.

[0014] The beneficial effect of the above solution is that by limiting the deformation range of the spring to 2mm to 5mm, the adaptive stroke is quantified, which can effectively absorb and compensate for sufficient working height error and vibration, ensuring adaptability, and avoid the device structure becoming loose or unstable due to excessive stroke.

[0015] Furthermore, the Z-axis adaptive component also includes:

[0016] A support plate, the support plate being connected to the elastic structure;

[0017] One or more telescopic structures, one end of which is connected to the support plate and the other end of which is connected to the mounting plate;

[0018] The telescopic structure's telescopic range in the Z-axis direction is adapted to the deformation range of the spring.

[0019] The beneficial effects of the above solution are that, by adding a telescopic structure and adapting it to the deformation range of the spring, this utility model provides guidance and stability for the lifting and lowering movement of the mounting plate, preventing it from deviating, jamming or twisting during the adaptive process, and ensuring smooth and reliable Z-axis movement; it also enhances the structural rigidity and motion accuracy of the entire Z-axis adaptive assembly.

[0020] Furthermore, the telescopic structure includes a first catheter and a second catheter;

[0021] The first conduit is connected to the support plate, and the second conduit is connected to the mounting plate. The second conduit is slidably inserted into the first conduit.

[0022] The first or second catheter is provided with a limiting part, which is used to limit the extension and retraction of the second catheter.

[0023] The beneficial effect of the above solution is that the present invention plays an overload protection role by setting the limiting part, preventing the spring from being damaged or malfunctioning due to excessive compression, thereby improving the reliability and service life of the device.

[0024] Furthermore, the adaptive base also includes a pitch angle compensation component, which includes:

[0025] A fixing block, wherein a bearing is provided on the fixing block;

[0026] A connecting shaft passes through the bearing and connects to the mounting plate, allowing the support plate to rotate about the connecting shaft.

[0027] The beneficial effect of the above solution is that, by adding a pitch angle compensation component, the entire scraping component (through the support plate) can rotate around a horizontal axis (connecting axis). This allows the scraping component to not only adapt to height changes but also to adapt to the pitch angle deviation (such as rotation around the Y-axis) of the surface being cleaned, ensuring that the scraper blade can fully fit the irregular or slightly tilted surface being cleaned, further improving the uniformity and reliability of cleaning.

[0028] Furthermore, the pitch angle compensation component also includes:

[0029] A response block, wherein the response block is disposed on the support plate;

[0030] A driving block, one end of which is connected to the connecting shaft, and the other end of which is in contact with the response block;

[0031] When the drive block rotates with the connecting shaft, it pushes the response block to make the support plate rotate around the connecting shaft, causing the scraping assembly to swing up and down around the connecting shaft to adapt to the angle changes of the surface of the object being cleaned and to maintain a constant contact pressure between the scraping assembly and the object being cleaned.

[0032] The beneficial effect of the above solution is that, through the cooperation mechanism of the drive block and the response block, this utility model converts the rotation of the connecting shaft (which may be triggered by external displacement or the angle of the object being cleaned) into the pitching and swaying of the support plate. This achieves a passive or active, automatic angle following compensation function, making the angle adaptation process more sensitive and automated, and continuously ensuring the best contact state.

[0033] Furthermore, the horizontal height of the driving block is higher than the horizontal height of the fixed block.

[0034] The beneficial effect of the above solution is that by limiting the horizontal height difference between the driving block and the fixed block, the lever arm of the lever action is defined and optimized, which can adjust the sensitivity and range of angle compensation, ensuring that the angle compensation action is both effective and does not overreact, thus improving the accuracy of control.

[0035] Furthermore, the adaptive base also includes a Y-axis compensation component, which comprises:

[0036] A first slider is slidably connected to the fixed block along the Y-axis direction;

[0037] A first driving member is connected to the fixed block to drive the fixed block to move along the Y-axis direction, so that the scraping assembly is aligned with the actual position of the object to be cleaned on the Y-axis.

[0038] The beneficial effect of the above solution is that, by adding a Y-axis compensation component, this utility model can drive the scraping component to move along the Y-axis to compensate for the positioning error of the coating head in the Y-axis direction. This solves the problem of misalignment between the scraping component and the coating head caused by mechanical repetitive positioning accuracy issues, ensuring that the scraping action always acts on the correct position and avoiding missed scraping or misalignment.

[0039] Furthermore, the adaptive base also includes an X-axis compensation component, which includes:

[0040] The second slider is slidably connected to the first slider along the X-axis direction;

[0041] A second driving member is connected to the first slider to drive the first slider to move along the X-axis direction, so that the scraping assembly is aligned with the actual position of the object to be cleaned on the X-axis.

[0042] The beneficial effect of the above solution is that by driving the scraping component to move along the X-axis (usually the coating direction), the present invention can adjust the position of the scraping component in the stroke or compensate for the deviation in this direction, thereby enhancing the adaptability and positioning accuracy of the entire system in multi-dimensional space.

[0043] Secondly, this utility model provides a scraping device, comprising:

[0044] The aforementioned adaptive base;

[0045] A wiping assembly, detachably mounted on the adaptive base, is used to wipe and clean the surface of the workpiece to be cleaned.

[0046] The beneficial effects of the above solution are that, by detachably mounting the scraping component on the adaptive base, this invention possesses multi-dimensional (Z-axis, pitch, X-axis, Y-axis) adaptive and compensatory capabilities, intelligently maintaining the scraping component in the optimal relative position and contact state with the cleaning object in complex motion. Furthermore, the detachable design of the scraping component facilitates replacement, maintenance, and cleaning, improving the equipment's usability and maintenance efficiency.

[0047] Compared with the prior art, the beneficial effects of this utility model include at least the following:

[0048] This invention, through the setting of the Z-axis adaptive component, enables the scraping component to automatically adapt to the height changes or slight undulations of the object being cleaned (such as the coating head) in the Z-axis direction, always maintaining a constant and appropriate contact pressure. This solves the problem that traditional rigid cleaning devices may damage the coating head due to excessive pressure or fail to clean thoroughly due to insufficient pressure. It ensures a stable and efficient cleaning effect without damaging the object being cleaned. Attached Figure Description

[0063] Furthermore, to provide the public with a better understanding of this utility model, certain specific details are described in detail in the following description. However, those skilled in the art can fully understand this utility model even without these detailed descriptions.

[0064] refer to Figure 1 The scraping device of this utility model includes: an adaptive base 300 and a scraping component 200.

[0065] When applying, refer to Figure 2The scraping assembly 200 includes a first assembly 21 and a second assembly 22 arranged sequentially along the extension direction of the slit 401 outlet. The first assembly 21 is located upstream of the second assembly 22, meaning that the first assembly 21 scrapes the coating liquid on the slit 401 first, and the second assembly 22 scrapes the coating liquid on the slit 401 subsequently. Further, each scraper assembly includes a first scraper 23 and a second scraper 24 arranged relatively parallel to each other, and both the first scraper 23 and the second scraper 24 are made of PFA or UHMW polymer material. The first scraper 23 includes a straight cutting edge 231, configured to scrape against the plane of the slit 401 outlet; the second scraper 24 includes a V-shaped cutting edge 241, configured to scrape against the side of the slit 401 outlet, and the second scraper 24 is located downstream of the first scraper 23. Specifically: First, the straight blade 231 of the first scraper 23 of the first component 21 is used to scrape the coating liquid on the surface of the slit 401 outlet for rough scraping. At this time, some of the coating liquid will be squeezed onto the side of the slit 401. Then, the V-shaped blade 241 of the second scraper 24 of the first component 21 is used to scrape the coating liquid on the side of the slit 401 for preliminary fine scraping. Next, the straight blade 231 of the first scraper 23 of the second component 22 is used to scrape the coating liquid on the surface of the slit 401 outlet, and the V-shaped blade 241 of the second scraper 24 of the second component 22 is used to scrape the coating liquid on the side of the slit 401 for secondary fine scraping to ensure cleaning effect.

[0066] In practical applications, refer to Figure 3 The straight cutting edge 231 includes a first cutting edge 2312 and a second cutting edge 2313. The second cutting edge 2313 connects to the first cutting edge 2312, and the angle between them is obtuse. The first cutting edge 2312 is configured to conform to the plane of the slit 401 outlet; the second cutting edge 2313 serves as a first guide surface to guide the coating liquid scraped off by the first cutting edge 2312. Furthermore, the lowest point of the V-shaped cutting edge 241 is provided with a second guide surface 2411, which can convert the sharp angle of the lowest point of the V-shaped cutting edge 241 into a flat angle, reducing the cleaning difficulty of the second scraper 24. Simultaneously, the second guide surface 2411 is parallel to the first guide surface, and the second guide surface 2411 and the first guide surface can guide all the waste liquid scraped off by the scraper to flow in the same direction, establishing a unified and efficient waste liquid outflow channel, greatly facilitating the centralized collection of waste liquid, maintaining the cleanliness of the working area, and preventing waste liquid dripping and contaminating products or equipment.

[0067] In actual implementation, the adaptive base 300 has multi-dimensional (Z-axis, pitch, X-axis, Y-axis) adaptive and compensation capabilities. The squeegee assembly 200 is detachably installed on the adaptive base 300, which not only facilitates replacement, maintenance and cleaning, improving the availability and maintenance efficiency of the equipment, but also intelligently maintains the squeegee assembly 200 in the optimal relative position and contact state with the cleaning object 400 in complex movement, so as to facilitate squeegee cleaning of the surface of the object to be cleaned.

[0068] The adaptive base 300 of this utility model includes: a mounting plate 31 and a Z-axis adaptive component 32.

[0069] In application, the mounting plate 31 is used to mount the scraping assembly 200. Preferably, the scraping assembly 200 is detachably mounted on the mounting plate 31. The Z-axis adaptive assembly 32 is disposed below the mounting plate 31 to enable the scraping assembly 200 to move adaptively along the Z-axis direction to maintain a constant contact pressure with the object being cleaned 400.

[0070] In practical applications, refer to Figure 4 The adaptive base 300 of this utility model may further include a pitch angle compensation component 33, a Y-axis compensation component 34, and an X-axis compensation component (not shown). The pitch angle compensation component 33 is disposed below the Z-axis adaptive component 32 and is used to enable the scraping component 200 to swing around the Y-axis in pitch angle. The Y-axis compensation component 34 is disposed below the pitch angle compensation component 33 and is used to drive the scraping component 200 to move along the Y-axis direction to compensate for positional deviation. The X-axis compensation component is disposed below the Y-axis compensation component 34 and is used to drive the scraping component 200 to move along the X-axis direction.

[0071] In actual implementation, refer to Figure 4 The adaptive base 300 of this utility model may also include a housing 35, with a mounting plate 31 mounted on the upper surface of the housing 35. The Z-axis adaptive component 32, the pitch angle compensation component 33, the Y-axis compensation component 34, and the X-axis compensation component are built into the housing 35 to protect each component.

[0072] To address the issues of traditional rigid cleaning devices potentially damaging the applicator due to excessive pressure or failing to clean thoroughly due to insufficient pressure, this invention ensures stable and efficient cleaning results without damaging the object being cleaned (400). The Z-axis adaptive component 32 of this invention includes one or more elastic structures 321.

[0073] When applying, refer to Figure 5Each elastic structure 321 includes a first support post 3211 and a spring 3212. One end of the spring 3212 is connected to the first support post 3211, and the other end of the spring 3212 is connected to the mounting plate 31. It is used to provide an elastic force that presses the scraping assembly 200 against the cleaning object 400, so that the scraping assembly 200 can move adaptively along the Z-axis direction to maintain a constant contact pressure with the cleaning object 400. Furthermore, the connection between the spring 3212 and the first support post 3211 can include at least two methods: (1) The spring 3212 is disposed on the top of the first support post 3211, one end of the spring 3212 is connected to the top of the first support post 3211, and the other end of the spring 3212 is connected to the mounting plate 31. (2) The spring 3212 is sleeved on the outside of the first support post 3211, one end of the spring 3212 is connected to the bottom of the first support post 3211, and the other end of the spring 3212 is connected to the mounting plate 31. Furthermore, in order to quantify the adaptive stroke of the Z-axis, effectively absorb and compensate for sufficient working height error and vibration to ensure adaptability, and avoid excessive stroke leading to loose or unstable device structure, this utility model limits the deformation range of spring 3212 to 2mm to 5mm.

[0074] In practical applications, the Z-axis adaptive component 32 may further include a support plate 322 and one or more telescopic structures 323. The support plate 322 is connected to the elastic structures 321. Preferably, multiple elastic structures 321 are evenly spaced on the support plate 322. One end of the telescopic structure 323 is connected to the support plate 322, and the other end is connected to the mounting plate 31. Preferably, multiple telescopic structures 323 are evenly spaced along the edge or at the four corners of the support plate 322. One end of each telescopic structure 323 is connected to the edge of the support plate 322, and the other end is connected to the edge of the mounting plate 31.

[0075] Furthermore, in order to provide guidance and stability for the lifting and lowering movement of the mounting plate 31, prevent it from skewing, jamming, or twisting during the adaptive process, ensure smooth and reliable Z-axis movement, and enhance the structural rigidity and motion accuracy of the entire Z-axis adaptive assembly 32, this invention adapts the extension and retraction range of the telescopic structure 323 in the Z-axis direction to the deformation range of the spring 3212.

[0076] During implementation, refer to Figure 5The telescopic structure 323 includes a first conduit 3231 and a second conduit 3232 that are interlocked. Specifically, the first conduit 3231 is connected to a support plate 322, and the second conduit 3232 is connected to a mounting plate 31. The second conduit 3232 is slidably inserted into the first conduit 3231. Furthermore, a limiting part (not shown) is provided on the conduit to limit the telescopic stroke of the second conduit 3232, which provides overload protection, preventing the spring 3212 from being excessively compressed and damaged or malfunctioning, thus improving the reliability and service life of the device. Furthermore, the limiting part of this utility model includes a first limiting step (not shown) and a second limiting step (not shown): when the compression of the spring 3212 is a first preset value, the second conduit 3232 abuts against the first limiting step, the contraction displacement of the first conduit 3231 and the second conduit 3232 reaches its maximum and cannot continue to contract, at which time the compression of the spring 3212 reaches its maximum; after the external force of compression on the spring 3212 disappears, when it continues to be subjected to tension, the spring 3212 stretches, when the stretch of the spring 3212 is a first preset value, the first conduit 3231 abuts against the second limiting step, the elongation displacement of the first conduit 3231 and the second conduit 3232 reaches its maximum and cannot continue to elongate, at which time the stretch of the spring 3212 reaches its maximum.

[0077] To enable the entire squeegee assembly 200 (via support plate 322) to rotate around a horizontal axis, allowing it to adapt not only to height changes but also to the tilt angle deviation (such as rotation around the Y-axis) of the surface of the object being cleaned 400, this ensures the squeegee blade makes full contact with the irregular or slightly tilted surface of the object being cleaned 400, further improving the uniformity and reliability of the cleaning process. (Refer to...) Figure 6 The pitch angle compensation component 33 of this utility model includes: a fixing block 331 and a connecting shaft 332.

[0078] In application, a bearing is provided on the fixing block 331, and a connecting shaft 332 passes through the bearing. The connecting shaft 332 connects to the mounting plate 31, allowing the support plate 322 to rotate around the connecting shaft 332. For details, please refer to [reference needed]. Figure 7 A first through hole 3312 is formed on the fixing block 331 along the Y-axis / X-axis direction. A first bearing 333 and a second bearing 334 are respectively provided on the hole walls at both ends of the first through hole 3312. The connecting shaft 332 is inserted into the first through hole 3312 and passes through the first bearing 333 and the second bearing 334, and is connected to the inner ring of the bearings. The connecting shaft 332 is parallel to the Y-axis / X-axis and can rotate around the Y-axis / X-axis when subjected to external force. Preferably, the connecting shaft 332 is parallel to the Y-axis.

[0079] Furthermore, two sets of adjustment units (the adjustment units are fixed blocks 331 and connecting shafts 332) can be set up. The two sets of adjustment units are arranged side by side along the Z-axis, and the connecting shaft 332 of one set of adjustment units is parallel to the Y-axis, while the connecting shaft 332 of the other set of adjustment units is parallel to the X-axis.

[0080] In practical applications, to make the angle adaptation process more sensitive and automated, and to continuously ensure the best contact state, the new pitch angle compensation component 33 of this machine also includes a response block and a drive block. Specifically, the response block is set on the support plate 322; one end of the drive block is connected to the connecting shaft 332, and the other end of the drive block is in contact with the response block; when the drive block rotates with the connecting shaft 332, it pushes the response block, causing the support plate 322 to rotate around the connecting shaft 332, causing the scraping component 200 to pitch around the connecting shaft 332 to adapt to the angle changes (e.g., tilt) of the surface of the object being cleaned 400, and to maintain a constant contact pressure between the scraping component 200 and the object being cleaned 400.

[0081] Furthermore, a first response block 335 and a second response block 336 are respectively provided at both ends of the support plate 322, and a first drive block 337 and a second drive block 338 are respectively provided at both ends of the connecting shaft 332. The first response block 335 and the first drive block 337 are in contact with each other, and the second response block 336 and the second drive block 338 are in contact with each other. During the cleaning process of the part to be cleaned, due to the different tilt angles of the part to be cleaned, the connecting shaft 332 can be driven to rotate clockwise or counterclockwise around the Y-axis / X-axis by the drive structure to adjust the angle of the scraping assembly 200 so that the blade of the scraping assembly 200 is aligned with the slit 401 of the part to be cleaned.

[0082] In actual implementation, the horizontal height of the drive block is higher than that of the fixed block 331. Furthermore, the difference in horizontal height between the drive block and the fixed block 331 can be limited according to actual needs to define and optimize the lever arm of the lever action. This allows for adjustment of the sensitivity and range of angle compensation, ensuring that the angle compensation action is both effective and does not overreact, thus improving the accuracy of control.

[0083] In order to drive the scraping assembly 200 to move along the Y-axis and compensate for the positioning error of the coating head in the Y-axis direction, this invention solves the problem of misalignment between the scraping assembly 200 and the coating head caused by mechanical repetitive positioning accuracy issues, ensuring that the scraping action always acts on the correct position and avoiding missed scraping or misalignment. The Y-axis compensation assembly 34 of this invention includes: a first slider 341 and a first driving member (not shown).

[0084] In application, the first slider 341 and the fixed block 331 are slidably connected along the Y-axis direction, and the first driving member is connected to the fixed block 331 to drive the fixed block 331 to move along the Y-axis direction, so that the scraping assembly 200 is aligned with the actual position of the cleaning object 400 on the Y-axis.

[0085] In practical applications, the first slider 341 has a first groove 342, and the fixing block 331 has a first protrusion 343 that matches the first groove 342. The first protrusion 343 is engaged in the first groove 342, forming a first slide rail extending along the Y-axis. The first driving member drives the fixing block 331, and the fixing block 331 moves along the Y-axis through the first slide rail, so that the scraping assembly 200 is aligned with the actual position of the cleaning object 400 on the Y-axis.
