Description

Technical Field

[0001] This application relates to the field of clamp technology, and in particular to a clamp and coating equipment. Background Technology

[0002] Pipe clamps are connecting tools used to connect pipes, serving as detachable connection points and playing an indispensable role in pipe connections. The tightening requirements of the clamps vary depending on the fluid flowing through the pipe. However, related technologies suffer from low efficiency in clamp installation and inspection. Utility Model Content

[0003] The main purpose of this application is to provide a clamp and coating equipment, which aims to at least improve the technical problem of low installation and testing efficiency of clamps.

[0004] To achieve the above objectives, according to some embodiments of this application, this application provides a clamp, including a first body, a second body, an adjusting rod, and a marking scale: the two ends of the first body are a first end and a second end, respectively; the two ends of the second body are a third end and a fourth end, respectively; the first end is used to connect with the third end, the second end is provided with a first mounting hole, and the fourth end is provided with a second mounting hole; the adjusting rod passes through the first mounting hole and is installed in the second mounting hole, and the adjusting rod is used to drive the second end to move toward or away from the fourth end; the first body and the second body can form an installation channel; the marking scale is installed on the second end or the fourth end, and the marking scale has a first identification area and a second identification area with different markings, the first identification area and the second identification area being arranged along the moving direction of the second end.

[0005] The system comprises a first body, a second body, an adjusting rod, and a marking scale. The adjusting rod drives the second end of the first body to move towards or away from the fourth end of the second body. The first and second bodies can form an installation channel. The marking scale is installed at the second or fourth end and has a first and a second identification area with different markings. The first and second identification areas are arranged along the direction of movement of the second end. During the locking process of the adjusting rod, the product's qualification can be determined by the different identification areas it points to. This embodiment has the advantage of high installation and inspection efficiency.

[0006] In some embodiments, the marking scale includes a color scale, wherein the color scale has a first identification area and a second identification area with different color markings.

[0007] By using different colors as distinguishing markers for the first and second identification areas, operators can determine whether a product is qualified based on the different colors, making the operation very convenient.

[0008] In some embodiments, the first identification area is provided with a first fluorescent layer, and the second identification area is provided with a second fluorescent layer, wherein the first fluorescent layer and the second fluorescent layer are of different colors. In other embodiments, the first identification area is provided with a first reflective layer, and the second identification area is provided with a second reflective layer, wherein the first reflective layer and the second reflective layer are of different colors.

[0009] By setting up a fluorescent layer, the high brightness of the phosphor allows for clear identification even in low light conditions; the reflective layer reflects bright colors, allowing operators to clearly determine whether the clamp is secure based on the color area being pointed to, thus improving the ease of identification.

[0010] In some embodiments, the color scale also has a third recognition area, wherein the second recognition area and the third recognition area are respectively located on both sides of the first recognition area along the moving direction of the second end, and the third recognition area and the first recognition area have different colors.

[0011] By setting up a third recognition area, it is possible to determine the situation where gaskets are not installed between pipes, which improves the detection type of color scale structure, something that wrench detection cannot do.

[0012] In some embodiments, the second identification region and the third identification region are the same color; or, the second identification region and the third identification region are different colors.

[0013] By setting the second and third recognition areas to be the same color, product quality can still be determined, simplifying the manufacturing process and reducing the number of colors used. Alternatively, by setting the second and third recognition areas to be different colors, product quality and the type of defect can be determined directly based on color.

[0014] In some embodiments, a first transition region is provided between the first identification region and the second identification region, and a second transition region is provided between the first identification region and the third identification region. The first transition region has a different color from both the first identification region and the second identification region, and the second transition region has a different color from both the first identification region and the third identification region.

[0015] By setting a first transition zone and a second transition zone, the operator can be prompted, reducing the risk of over-tightening.

[0016] In some embodiments, the color scale includes a substrate layer, a coating layer, and a transparent film layer arranged sequentially from the inside out, wherein the coating layer covers the outer periphery of the substrate layer, and the transparent film layer covers the outer periphery of the coating layer.

[0017] By setting a color scale, which includes a substrate layer, a coating layer, and a transparent film layer arranged sequentially from the inside out, the substrate layer can provide a certain strength and hardness, the coating layer can provide a variety of colors, and the transparent film layer can protect the coating layer.

[0018] In some embodiments, the marking scale has a first identification area and a second identification area with different shapes.

[0019] By setting different shaped markers to distinguish between the first and second identification areas, different distinguishing markers can be set according to needs and actual processing conditions.

[0020] In some embodiments, the second end has a first plate body with the first mounting hole provided on the first plate body, the fourth end has a second plate body with the second mounting hole provided on the second plate body, the first plate body and the second plate body are arranged in parallel, and the color scale is arranged perpendicularly to the second plate body.

[0021] By setting a first plate and a second plate, with the first plate and the second plate arranged in parallel, the first plate moves toward the second plate when the adjusting rod moves, and the color scale is set perpendicular to the second plate, which makes it easy to identify.

[0022] In some embodiments, the second plate is provided with an indicator arrow pointing to the marking scale.

[0023] By setting indicator arrows, operators can easily read the position of the color scale directly with their eyes, making it convenient to judge whether the tightening is in place or qualified.

[0024] In some embodiments, both the first mounting hole and the second mounting hole are threaded holes, and the adjusting rod is a threaded rod that is rotatable to move within the second mounting hole along its own central axis.

[0025] By setting a threaded rod and a threaded hole to adjust the position of the adjusting rod, not only is the adjustment convenient and progressive, but it also has high connection strength.

[0026] In some embodiments, a notch is provided at the opening of the first mounting hole, and a buckle is provided on the adjusting rod to engage with the notch.

[0027] By setting a buckle on the adjusting rod and creating a notch in the first mounting hole to engage with the buckle, installation can be completed in one step, improving installation efficiency.

[0028] In some embodiments, the first body and the second body are both semi-circular in shape, and the first end and the third end are hinged to form a hinge point. The first body and the second body can rotate around the hinge point so that the second end and the fourth end move closer to or further away from each other.

[0029] By setting the first body and the second body to be hinged to each other, the clamp can be opened and closed by the relative rotation of the two during installation, which is convenient to operate.

[0030] According to some embodiments of this application, this application provides a coating device, which includes a first pipe and a second pipe, a first flange sleeved on the first pipe, a second flange sleeved on the second pipe, a gasket disposed between the first flange and the second flange, and also includes the clamps described above, with the first flange and the second flange disposed within the installation channel.

[0045] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0046] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this embodiment are only used to explain the relative positional relationship and movement of each component in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indicator will also change accordingly.

[0047] Furthermore, the use of terms such as "first," "second," etc., in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0048] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0049] Furthermore, the technical solutions of the various embodiments of this application can be combined with each other, but only if they are feasible to those skilled in the art.

It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0050] The descriptions of directions such as "up", "down", "front", "back", "left", and "right" in this application are based on the directions shown in the figure and are only used to explain the relative positional relationship between the components in the posture shown in the figure. If the specific posture changes, the directional indication will also change accordingly.

[0051] Currently, judging from market trends, the application of power batteries is becoming increasingly widespread. Power batteries are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but also widely applied in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in aerospace and other fields. With the continuous expansion of power battery applications, market demand is also constantly increasing.

[0052] Electrode coating is a crucial step in the manufacturing of power batteries. Coating is achieved using coating equipment, which injects various slurries that are transported through pipes and then coated onto the electrode sheets. These pipes are connected using clamps. Since the tightness of the clamps directly affects the tightness of the connection between the two pipes, loose clamps pose a risk of leakage. Therefore, the control of the clamp tightening force is quite stringent.

[0053] After careful study, the applicant discovered that the relevant technology generally involves first tightening the screws of the clamp to lock the two pipes together, and then using a torque wrench to check the torque, thus controlling the tightening force. However, using a torque wrench for testing is inefficient, and if the torque is not up to standard, it needs to be adjusted and checked again with a torque wrench, further reducing the testing efficiency.

[0054] Therefore, the applicant provides a clamp.

[0055] Reference Figures 1 to 3 According to some embodiments of this application, this application provides a clamp 100, including a first body 10, a second body 20, an adjusting rod 30, and a marking scale 40. The two ends of the first body 10 are a first end 11 and a second end 12, respectively. The two ends of the second body 20 are a third end 21 and a fourth end 22, respectively. The first end 11 is used to connect with the third end 21. The second end 12 is provided with a first mounting hole 122, and the fourth end 22 is provided with a second mounting hole 223. The adjusting rod 30 passes through the first mounting hole 122 and is installed in the second mounting hole 223. The adjusting rod 30 is used to drive the second end 12 to move toward or away from the fourth end 22. The first body 10 and the second body 20 can form an installation channel 50. The marking scale 40 is installed on the second end 12 or the fourth end 22. The marking scale 40 has a first identification area 411 and a second identification area 412 with different markings. The first identification area 411 and the second identification area 412 are arranged along the moving direction of the second end 12.

[0056] The first body 10 and the second body 20 are two parts that make up the clamp 100. The two parts can be spliced ​​and assembled to form an installation channel 50, which is used to install the pipes or flanges that need to be connected. In a specific application scenario, the clamp 100 can be used to connect a first pipe and a second pipe. The first flange is fitted at the connection port of the first pipe, and the second flange is fitted at the connection port of the second pipe. The clamp 100 is used to fit around the outer periphery of the first flange and the second flange, and the first body 10 and the second body 20 are locked together by the adjusting rod 30, thereby locking the first flange and the second flange along the normal direction of the first flange and the second flange, and thus connecting the first pipe and the second pipe.

[0057] The first body 10 and the second body 20 can be two separate parts. The first end 11 and the third end 21 can be connected by a threaded connection, and the second end 12 and the fourth end 22 can be connected by an adjusting rod 30. In another embodiment, the first body 10 and the second body 20 can be a connected structure, with the first end 11 and the third end 21 hinged by a hinge rod. During installation, simply rotate the first body 10 or the second body 20 around the hinge point to bring the second end 12 and the fourth end 22 closer together, and then lock them together by the adjusting rod 30. During disassembly, rotate the first body 10 and the second body 20 around the hinge point to move them apart, allowing the pipe or flange to be removed. Of course, the first end 11 and the third end 21 can also be connected by the adjusting rod 30, allowing the distance between the first end 11 and the third end 21 to be adjusted. In the above embodiments of this application, the marking scale 40 is provided on the second end 12 or the fourth end 22. This means that the marking scale 40 can be provided on the second end 12 of the first body 10 or on the fourth end 22 of the second body 20. When it is provided on the second end 12, the marking scale 40 will move with the movement of the second end 12. When it is provided on the fourth end 22, the marking scale 40 will not move. The end face of the second end 12, that is, the side facing the fourth end 22, can be used as the indicator mark, and the position of the end face alignment can be used as the position pointing to the marking scale 40. Alternatively, an indicator arrow 13 can be provided on the second end 12, and the position pointed to by the indicator arrow 13 can be used as the position for the operator to read, such as the first identification area 411 or the second identification area 412.

[0058] The marking scale 40 has a first identification area 411 and a second identification area 412 with different markings. The markings in the different markings can be different in color, shape, texture or other forms. All forms that can distinguish the first identification area 411 and the second identification area 412 are within the protection scope of this application. The second end 12 can move toward the fourth end 22 under the drive of the adjusting rod 30. The first identification area 411 and the second identification area 412 are arranged along the moving direction of the second end 12. For example, when the marking scale 40 is set at the fourth end 22, the marking scale 40 is stationary. When the second end 12 moves toward the fourth end 22, the second end 12 can point to different identification areas. Pointing to different identification areas can indicate the relative distance between the second end 12 and the fourth end 22. The relative distance between the second end 12 and the fourth end 22 can reflect the degree of tightening of the clamp 100. Thus, the degree of tightening of the clamp 100 can be judged by which identification area the second end 12 points to. For example, the degree of tightening of the clamp 100 can be judged by which identification area the end face of the second end 12 or the indicator arrow 13 set on the second end 12 points to. Similarly, when the marking scale 40 is set at the second end 12, the marking scale 40 will move with the second end 12. When the second end 12 moves towards the fourth end 22, the fourth end 22 can point to different recognition areas. Pointing to different recognition areas indicates the relative distance between the second end 12 and the fourth end 22. The relative distance between the second end 12 and the fourth end 22 reflects the degree of tightening of the clamp 100. Therefore, the degree of tightening of the clamp 100 can be judged by which recognition area the fourth end 22 points to. When designing the clamp 100, different recognition areas can be set according to the different tightening force ranges of the clamp 100. Thus, the tightening force range of the clamp 100 can be judged by the recognition area it points to, thereby judging whether the clamp 100 is installed correctly. In this way, the installation of the clamp 100 can be determined by visual recognition during the installation process, and the inspection can also be completed by visual recognition. Compared with the need to measure each clamp individually with a torque wrench, this example has the advantages of high installation efficiency and high inspection efficiency. Specifically, this application constructs a closed-loop quality control system for the locking operation of lithium battery production pipelines by visualizing mechanical parameters and identifying safety warnings for specific areas. Compared with traditional torque wrench detection solutions, this design reduces the single-point detection time from 120 seconds to 3 seconds and reduces manual verification workload by 87%, providing a highly reliable, low-cost, standardized locking solution for large-scale lithium battery manufacturing.

[0059] The clamp 100 includes a first body 10, a second body 20, an adjusting rod 30, and a marking scale 40. The adjusting rod 30 drives the second end 12 of the first body 10 to move toward or away from the fourth end 22 of the second body 20. The first body 10 and the second body 20 can form an installation channel 50. The marking scale 40 is installed on the second end 12 or the fourth end 22. The marking scale 40 has a first identification area 411 and a second identification area 412 with different markings, and the first identification area 411 and the second identification area 412 are arranged along the moving direction of the second end 12. During the locking process of the adjusting rod 30, the product's qualification can be determined by pointing to different identification areas. This embodiment has the advantage of high installation and testing efficiency.

[0060] Reference Figure 1 In some embodiments, the second end 12 is provided with an indicator arrow 13 pointing to the indicator scale 40.

[0061] As mentioned above, the side of the second end 12 facing the fourth end 22 can be used as an indicator, or an indicator can be set on the second end 12, namely the indicator arrow 13 in this embodiment, with the head of the arrow pointing in the direction of the indicator scale 40. Figure 1 As shown, it can also be positioned on the side closer to the first end 11. Of course, as... Figure 7 As shown, the indicator arrow 13 can be positioned on the side away from the first end 11. Of course, when the second end 12 has a second plate 221, the indicator arrow 13 can be positioned on the second plate 221. In this way, as the second end 12 moves toward the fourth end 22, the indicator arrow 13 also moves with the second end 12, thereby pointing to different positions on the color scale 41.

[0062] By setting the indicator arrow 13, the operator can easily read the position of the indicator color scale 41 with their own eyes, making it convenient to judge whether the tightening is in place or qualified.

[0063] Reference Figure 3 In some embodiments, the marking scale 40 includes a color scale 41, which has a first recognition area 411 and a second recognition area 412 with different color markings.

[0064] The color scale 41 refers to the fact that the colors of the first recognition area 411 and the second recognition area 412 of the indicator scale are different, such as Figure 3As shown, the first identification area 411 is below the second identification area 412. The first identification area 411 can be green, and the second identification area 412 can be red. If the color scale 41 is installed on the fourth end 22, during the locking process of the adjusting rod 30, an indicator mark, such as an indicator arrow 13, can be set on the second end 12. When the second end 12 moves towards the fourth end 22, if the indicator arrow 13 points to the red second identification area 412, it means that it has not been locked yet and the adjusting rod 30 needs to be tightened further. If the indicator arrow 13 points to the green first identification area 411, it means that the locking force is within the qualified range and the product is locked successfully. In this visual way, the operator can judge whether the product is qualified by visually identifying different color marks, which greatly improves the production efficiency and inspection efficiency.

[0065] By using different colors as distinguishing markers for the first identification area 411 and the second identification area 412, the operator can determine whether the product is qualified based on the different colors, making the operation very convenient.

[0066] In some embodiments, a first identification area 411 is provided with a first fluorescent layer, and a second identification area 412 is provided with a second fluorescent layer. The first and second fluorescent layers are of different colors. The fluorescent layers contain phosphors, and different colors of phosphors can display different colors. The different colors of the first and second phosphor layers indicate that the first identification area 411 and the second identification area 412 are of different colors. In low-light environments, ordinary paint or markers may be difficult to see, while phosphors can emit greater brightness, making them particularly suitable for use in low-light conditions. In other embodiments, a first identification area 411 is provided with a first reflective layer, and a second identification area 412 is provided with a second reflective layer. The first and second reflective layers are of different colors. A reflective layer is one that can reflect a bright light under illumination, making it easier for the operator to identify. Here, the first and second reflective layers are also of different colors, resulting in different colors for the first identification area 411 and the second identification area 412. The advantage of setting up a reflective layer is that, in low light conditions, external light sources such as flashlights can be used to illuminate the area, and the bright colors reflected by the reflective layer can be used to clearly determine which identification area is being pointed to, thereby determining whether the clamp 100 is properly locked.

[0067] By setting a fluorescent layer, the high brightness of the fluorescent powder allows for clear identification even in low light conditions; the reflective layer reflects bright colors, allowing the operator to clearly determine whether the clamp 100 is secure based on the color area being pointed to, thus improving the ease of identification.

[0068] Reference Figure 4In some embodiments, the color scale 41 also has a third recognition area 413. The second recognition area 412 and the third recognition area 413 are respectively located on both sides of the first recognition area 411 along the moving direction of the second end 12. The third recognition area 413 and the first recognition area 411 have different colors.

[0069] An indicator arrow 13 can be set on the second end 12 as an indicator, or the end face of the second end 12 facing the fourth end 22 can be used as an indicator. The color of the identification area on the color scale 41 pointed to by the indicator is used to determine whether the clamp 100 is qualified. When the color scale 41 is installed on the fourth end 22, during the locking process of the adjusting rod 30, the indicator usually points to the second identification area 412 first, indicating that the clamp 100 is not yet locked, the distance between the second end 12 and the fourth end 22 is large, and the locking force is insufficient. As the adjusting rod 30 is rotated to lock, the indicator arrow 13 moves towards the fourth end 22 and points to the first identification area 411, indicating that the locking force is sufficient and the clamp 100 is locked qualified.

[0070] Specifically, the design approach involves first establishing a mechanical database of the clamp 100's locking state. A 3D laser scanner is used to reverse engineer typical pipe interfaces, and combined with measured data from pressure sensors, a contact pressure distribution model of the pipe sealing surface is constructed. For common failure modes (such as missing gaskets, clamp 100 fatigue deformation, etc.), a torque monitoring device is used to conduct over 300 opening and closing tests, statistically determining the safe locking torque threshold to be 35-50 N·m. The innovatively designed dynamic scale uses a color-gradient structure, converting the acceptable torque range of the clamp 100 into an indicator arrow 13 pointing to the first identification area 411. If the clamp 100 is not locked, the indicator stays in the second identification area 412; if no gasket is installed between flanges, the indicator arrow 13 stays in the third identification area 413. Only when the gasket between flanges is properly installed and locked will the indicator arrow 13 stay in the first identification area 411, indicating that the clamp 100 is correctly tightened. In related technologies, using a wrench to measure torque is not only inefficient but also difficult to detect whether gaskets are installed between pipes. In a specific embodiment, when the torque is 0-30 N·m, corresponding to the clamp 100 not being fully engaged, the indicator arrow 13 points to the second identification area 412, indicating a risk of gasket misalignment or thread stripping; when the torque is 30-55 N·m, the indicator points to the first identification area 411, indicating normal installation. When the indicator points to the third identification area 413, it indicates that the gasket is not correctly installed on the pipe or flange. This application addresses the technical challenge of quantifying the clamp 100 locking status during equipment changeover by innovatively developing a torque visualization system based on a color-coded scale 41. Through the coupled design of mechanical parameters and visual indicators, it achieves accurate judgment and efficient management of the pipe locking status.

[0071] By setting the third recognition area 413, it is possible to determine the situation where gaskets are not installed between pipes, which improves the detection type of color scale structure, something that wrench detection cannot do.

[0072] In some embodiments, the second recognition area 412 and the third recognition area 413 are the same color; or, the second recognition area 412 and the third recognition area 413 are different colors.

[0073] The first identification area 411 can be green, while the second identification area 412 and the third identification area 413 can be the same color, for example, both red, indicating non-compliance. However, the reasons for non-compliance in the two identification areas are different. When the indicator arrow 13 points to the second identification area 412, it indicates that it is not tightened correctly. When the indicator arrow 13 moves past the first identification area 411 (indicating compliance) and points to the third identification area 413, it indicates that a gasket is not installed between the flanges. The operator can determine the cause of non-compliance by observing whether the red color, symbolizing non-compliance, appears before or after the green color during the tightening process. If it appears before the green color, it indicates that it is not tightened; if it appears after the green color, it indicates that a gasket is not installed. Of course, this determination of the type of non-compliance requires observation of the tightening process. To more quickly identify the type of non-compliance during re-inspection, the colors of the second identification area 412 and the third identification area 413 can be designed to be different, such as the second identification area 412 being red and the third identification area 413 being yellow. This allows for direct judgment of compliance and the type of non-compliance based on the color.

[0074] By setting the second recognition area 412 and the third recognition area 413 to have the same color, it is still possible to determine whether the product is qualified, and this simplifies the manufacturing process and reduces the number of colors used. By setting the second recognition area 412 and the third recognition area 413 to have different colors, it is possible to directly determine whether the product is qualified and the type of non-qualification based on the color.

[0075] Reference Figure 4 In some embodiments, a first transition region 414 is provided between the first identification region 411 and the second identification region 412, and a second transition region 415 is provided between the first identification region 411 and the third identification region 413. The first transition region 414 has a different color from the first identification region 411 and the second identification region 412, and the second transition region 415 has a different color from the first identification region 411 and the third identification region 413.

[0076] The first transition zone 414 and the second transition zone 415 are set up to serve as prompts. For example, when the adjusting rod 30 is moved or tightened until the indicator arrow 13 points to the first transition zone 414, it indicates to the operator that the first identification zone 411, which is the qualified zone, is about to be reached. This allows the operator to slow down the movement or tightening speed, reducing the risk of exceeding the tightening limit. When the adjusting rod 30 is moved or tightened until the indicator arrow 13 points to the second transition zone 415, it indicates that the qualified zone has been exceeded, and there is a situation where a gasket is not installed between the pipes or flanges. The movement or tightening speed should also be slowed down to reduce the risk of damage to the pipes or flanges. At the same time, setting transition zones can also reduce the risk of misjudging critical states, effectively improving the operator's identification accuracy.

[0077] By setting the first transition zone 414 and the second transition zone 415, the operator can be prompted, reducing the risk of over-tightening.

[0078] In some embodiments, the color scale 41 includes a substrate layer, a coating layer, and a transparent film layer arranged sequentially from the inside out, with the coating layer covering the outer periphery of the substrate layer and the transparent film layer covering the outer periphery of the coating layer.

[0079] The base layer can be made of metal materials to provide a certain strength and hardness, such as stainless steel base strip. The coating layer is a colored coating, such as red, yellow or green. The outer transparent film layer is a transparent film that allows the color of the coating layer to pass through, that is, the human eye can see the color of the coating through the transparent film layer. The wrapping film layer can reduce the risk of the coating falling off. To improve the wear resistance of the transparent film layer, PET film can be used. The full English name of PET is Polyethylene Terephthalate.

[0080] By setting a color scale 41, which includes a substrate layer, a coating layer, and a transparent film layer arranged sequentially from the inside out, the substrate layer can provide a certain strength and hardness, the coating layer can provide a variety of colors, and the transparent film layer can protect the coating layer.

[0081] Reference Figure 6 In some embodiments, the marking scale 40 has a first identification area 411 and a second identification area 412 with different shapes.

[0082] The preceding description describes an embodiment that uses color coding to distinguish between the first identification area 411 and the second identification area 412. For example, the first identification area 411 is green, and the second identification area 412 is red. When the indicator points to red, the identification is unqualified; when the indicator points to green, the identification is qualified. Of course, different shapes can also be used for differentiation, such as a circle within the first identification area 411 and a triangle within the second identification area 412. As an extended embodiment of this example, different stripes can also be used to distinguish between the first identification area 411 and the second identification area 412, such as... Figure 6 The first identification area 411 is set with a checkered pattern, and the second identification area 412 is set with diagonal lines. Any shape or stripe mark that can distinguish the first identification area 411 and the second identification area 412 is within the scope of protection of this application.

[0083] By setting different shaped marks to distinguish the first identification area 411 and the second identification area 412, different distinguishing marks can be set according to needs and actual processing conditions.

[0084] In some embodiments, the second end 12 has a first plate 121 with a first mounting hole 122, and the fourth end 22 has a second plate 221 with a second mounting hole 223. The first plate 121 and the second plate 221 are arranged in parallel, and the color scale 41 is arranged vertically on the second plate 221.

[0085] Both the first plate 121 and the second plate 221 are plate-shaped. A first mounting hole 122 is provided through the first plate 121 along its thickness direction, and a second mounting hole 223 is provided along the second plate 221 along its thickness direction. The central axes of the first mounting hole 122 and the second mounting hole 223 coincide, and their diameters are nearly equal. The first plate 121 and the second plate 221 are arranged parallel to each other. This allows the adjusting rod 30 to move as close as possible along the central axis of the first mounting hole 122 during movement, reducing the risk of tilting. The color scale 41 is vertically mounted on the second plate 221 and will not interfere with the movement of the first plate 121.

[0086] By setting a first plate 121 and a second plate 221, with the first plate 121 and the second plate 221 arranged in parallel, when the adjusting rod 30 moves, it drives the first plate 121 to move toward the second plate 221. The color scale 41 is set vertically on the second plate 221, which can facilitate identification.

[0087] In some embodiments, the first mounting hole 122 and the second mounting hole 223 are both threaded holes, and the adjusting rod 30 is a threaded rod that can rotate to move within the second mounting hole 223 along its own central axis.

[0088] The outer circumferential surface of the threaded rod is threaded, allowing it to be threadedly connected to the second mounting hole 223 and also to the first mounting hole 122. During tightening, as the threaded rod rotates, it gradually extends into the second mounting hole 223, simultaneously causing the second end 12 to move towards the fourth end 22.

[0089] The position of the adjusting rod 30 is adjusted by setting a threaded rod and a threaded hole to fit together. This not only makes adjustment convenient and enables gradual adjustment, but also provides high connection strength.

[0090] Reference Figure 8 In some embodiments, a notch 222 is provided at the opening of the first mounting hole 122, and a buckle 31 is provided on the adjusting rod 30 to engage with the notch 222.

[0091] A notch 222 is provided at the opening of the first mounting hole 122 on the side opposite to the second mounting hole 223. A buckle 31 is provided on the adjusting rod 30 to engage with the notch 222. This allows the adjusting rod 30 to be positioned so that when the buckle 31 engages with the notch 222, the adjusting rod 30 is precisely in the position where the clamp 100 is properly secured, i.e., the position indicated by the arrow 13 pointing to the first identification area 411 indicating compliance. The adjusting rod 30 can be a smooth rod, allowing direct insertion from the first mounting hole 122 into the second mounting hole 223, improving installation convenience. In other embodiments, a spring buckle 31 can be provided, with a spring inside the adjusting rod 30 and a stop block installed at the free end of the spring, keeping the spring in a compressed state. Alternatively, a pull rod can be provided on the adjusting rod 30, blocking the end of the stop block away from the spring, preventing the stop block from moving. When installation is required, pull out the lever to stop obstructing the abutment block. At this time, the abutment block is driven to move toward the second mounting hole 223 under the action of the elastic restoring force of the spring, which can also achieve one-step installation.

[0092] By setting a buckle 31 on the adjusting rod 30 and setting a notch 222 in the first mounting hole 122 to cooperate with the buckle 31, installation can be completed in one step, improving installation efficiency.

[0093] In some embodiments, the first body 10 and the second body 20 are both semi-circular in shape, and the first end 11 and the third end 21 are hinged to form a hinge point. The first body 10 and the second body 20 can rotate around the hinge point so that the second end 12 and the fourth end 22 move closer to or further away from each other.

[0094] The semi-circular shape can be square, semi-circular or semi-elliptical. Depending on the shape of the flange or pipe, a semi-circular shape can generally be used. The first end 11 and the third end 21 are hinged so that the first body 10 and the second body 20 can rotate relative to each other. When the clamp 100 needs to be locked, the second end 12 and the fourth end 22 can be brought closer to each other. When the clamp 100 needs to be opened, the second end 12 and the fourth end 22 can be moved away from each other.

[0095] By setting the first body 10 and the second body 20 to be hinged to each other, the clamp 100 can be opened and closed by the relative rotation of the two during installation, which is convenient to operate.

[0096] According to some embodiments of this application, this application provides a clamp 100, including a first body 10, a second body 20, an adjusting rod 30, and a color scale 41. The two ends of the first body 10 are a first end 11 and a second end 12, respectively; the two ends of the second body 20 are a third end 21 and a fourth end 22, respectively; the first end 11 is hinged to the third end 21; the second end 12 is provided with a first mounting hole 122; and the fourth end 22 is provided with a second mounting hole 223; the adjusting rod 30 passes through the first mounting hole 122 and is mounted in the second mounting hole 223, and the adjusting rod 30 is used to drive the second end 12 toward or away from the fourth end. 22. The first body 10 and the second body 20 can be arranged to form an installation channel 50. A color scale 41 is installed at the fourth end 22. An indicator mark pointing to the color scale 41 is provided on the second end 12. The color scale 41 has a first identification area 411, a second identification area 412, and a third identification area 413. The first identification area 411 and the third identification area 413 are respectively located on both sides of the second identification area 412 along the moving direction of the second end 12. The second identification area 412 is different in color from the first identification area 411, and the third identification area 413 is different in color from the first identification area 411. In some specific embodiments, the second end 12 has a first plate 121, on which a first mounting hole 122 is provided. The fourth end 22 has a second plate 221, on which a second mounting hole 223 is provided. The first plate 121 and the second plate 221 are arranged parallel to each other, and the color scale 41 is arranged perpendicularly to the second plate 221. The color scale 41 comprises a substrate layer, a coating layer, and a transparent film layer arranged sequentially from the inside out. The coating layer covers the outer periphery of the substrate layer, and the transparent film layer covers the outer periphery of the coating layer. Both the first mounting hole 122 and the second mounting hole 223 are threaded holes. The adjusting rod 30 is a threaded rod, capable of rotation to move within the second mounting hole 223 along its own central axis. This clamp 100 has the advantages of high installation efficiency and the ability to quickly detect whether the installation is qualified.

[0097] According to some embodiments of this application, this application provides a coating device, which includes a first pipe and a second pipe, a first flange sleeved on the first pipe, a second flange sleeved on the second pipe, a gasket disposed between the first flange and the second flange, and also includes the aforementioned clamp 100, with the first flange and the second flange disposed within an installation channel 50.

[0098] Coating equipment is used to coat the surface of electrode sheets for battery manufacturing with a slurry to form positive or negative electrode sheets. The coating machine requires various slurry raw materials and has many pipes inside. The pipes are connected by flanges, and a gasket is placed between the two connecting flanges. In a specific embodiment, the pipes include a first pipe and a second pipe that need to be connected to each other. A first flange is fitted on the first pipe, and a second flange is fitted on the second pipe. The first pipe and the second pipe are connected by connecting the first flange and the second flange. The clamp 100 forms an installation channel 50, which is actually a through hole. The first flange and the second flange are placed in the installation channel 50 and locked together by the adjusting rod 30, realizing the connection between the first pipe and the second pipe. If a gasket is placed between the first flange and the second flange, the adjusting rod 30 will not be able to be turned when the indicator points to the first identification area 411. If it can be turned further until the indicator points to the third identification area 413, it indicates that no gasket is placed between the first flange and the second flange, which is also a case of unqualified installation. In other words, the color scale 41 of the clamp 100 can not only detect whether the clamp 100 is tight, but also detect whether there is a shim, which is something that traditional torque wrenches cannot do.

[0099] In some embodiments, a U-shaped groove is provided on the inner wall surface of the installation channel 50. The groove is 1.2 mm deep and 2.5 mm wide. It is batch-processed using a CNC lathe to ensure a dimensional tolerance of ±0.05 mm. Part of the clamp 100 may also be clamped on the outer wall of the pipe. The U-shaped groove can be used to cooperate with the pipe to clamp the pipe.

[0100] The above description is merely an optional embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the content of the specification and drawings of this application under the concept of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
