Description

Technical Field

[0001] This utility model relates to the field of vacuum insulation panel processing technology, and in particular to a VIP panel edge pulling mechanism. Background Technology

[0002] VIP panels (vacuum insulation panels) consist of an outer barrier film, an inner core of glass fiber cotton, and a getter. During the vacuum process, the vacuum chamber is evacuated to a high vacuum (approximately 5 x 10⁻⁶). -2 The vacuum level inside the VIP board barrier film is consistent with that inside the vacuum chamber, completing the sealing operation. After the vacuum is completed, the vacuum chamber is depressurized and air is drawn in. The air pressure is restored to atmospheric pressure. At this time, the inside of the VIP board maintains a high vacuum, while the outside is atmospheric pressure. The core material is compressed due to atmospheric pressure. Before compression, the side film bag and the core material thickness are the same. After compression, the core material size decreases, and the excess part of the film bag (i.e., barrier film) will be sucked at the edge of the core material. The sucked edge will affect the product's folding, size, appearance quality, etc.

[0003] To solve the problem of edge suction, the industry has been using manual methods to pull out the suction edges. However, the pulling force and speed are uncontrollable during manual operation. Excessive or concentrated force on the film bag can easily damage it, leading to air leakage and product scrapping. In addition, the manual edge pulling process is labor-intensive and can easily cause fatigue. Furthermore, the barrier film undergoes plastic deformation and becomes thinner during the edge pulling process, reducing its barrier performance and affecting product quality. Utility Model Content

[0004] This application discloses a VIP board edge pulling mechanism to solve the problems of uneven manual pulling force, severe plastic deformation of the barrier film, and high labor intensity of workers in the prior art.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A VIP board edge pulling mechanism, comprising:

[0007] The placement platform is used to place the VIP board;

[0008] Multiple clamping components are evenly distributed on the same side of the placement platform, with adjacent clamping components spaced apart. The clamping components are used to clamp the side film bag on one side of the VIP board so as to generate sufficient friction during the edge pulling process to provide pulling force for the side film bag to pull out the suction edge.

[0009] Multiple edge-pulling components are located on the same side of the placement platform, and each edge-pulling component corresponds to a clamping component. The clamping components are connected to the edge-pulling components, and the edge-pulling components are used to provide pulling force to the clamping components to pull out the suction edge.

[0010] The technical solution adopted in this utility model can achieve the following beneficial effects:

[0011] 1. This utility model involves placing a VIP board that needs to be pulled along its edges on a placement platform. The side film bag on one side of the VIP board is clamped by multiple clamping components to provide sufficient friction. Then, the pulling components provide a stable pulling speed to pull the side film bag on one side of the VIP board out as a whole. After the side film bag on one side of the VIP board is pulled out, the clamping components release the side film bag on that side, and the pulling components reset. Then, the side film bags on the other sides of the VIP board are pulled out one by one to complete the pulling out of the VIP board. The force is controlled within the plastic deformation range by the pulling components to maintain the performance of the barrier film and ensure product quality.

[0012] 2. This utility model adopts a multi-module parallel arrangement, which makes the pulling force more uniform and allows the entire single side to be pulled out simultaneously, thus improving efficiency;

[0013] 3. This utility model achieves uniform and controllable tension of the VIP board, reduces the air leakage and scrap rate in the edge-pulling process, and reduces the product scrap rate;

[0014] 4. This utility model ensures that the product has sufficient plasticity reserve by controlling the tensile force within the plastic deformation range, reducing the scrap rate of products in subsequent processes, and ensuring that the barrier film does not become thin due to plastic deformation, thus guaranteeing the barrier performance.

[0015] 5. This utility model improves edge-pulling efficiency and reduces company management costs such as personnel and inventory;

[0016] 6. This utility model reduces the labor intensity of operators. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," "third," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0029] The utility model concept of this application is described here:

[0030] The inventors discovered in practice that, since the industry standard is to manually pull out the suction edge using pliers, the pulling force and speed are uncontrollable during manual operation. Excessive or concentrated force on the film bag can easily damage it, leading to product leakage and scrapping. Manual pulling can only be done at a single point, and the pulling force is distributed among adjacent areas, requiring a large pulling force to pull out the suction edge. At the same time, the manual pulling process is labor-intensive and can easily cause fatigue. Long-term operation may cause hand deformities, affecting the health of employees. Furthermore, the barrier film undergoes plastic deformation and thins during the pulling process, reducing its barrier performance and affecting product quality.

[0031] Based on this, the inventor provides a VIP board edge pulling mechanism that allows the pulling force during the edge pulling process to be controlled within the plastic deformation range, ensuring that the product has sufficient plastic reserve, reducing the scrap rate of products in subsequent processes, and preventing the barrier film from thinning due to plastic deformation, thus ensuring barrier performance. At the same time, it avoids the problem of uncontrollable pulling force and pulling speed by operators, reducing the labor intensity of operators.

[0032] The following is in conjunction with the appendix Figures 1 to 4 The present application provides a detailed description of a VIP board edge-pulling mechanism through specific embodiments and application scenarios.

[0033] Reference Figure 1 and Figure 2 A VIP board edge pulling mechanism includes: a placement platform 100, multiple clamping components 200, and multiple edge pulling components 300;

[0034] Specifically, refer to Figure 1 The VIP board edge pulling mechanism also includes a frame 20, a workbench 30 is mounted on the top of the frame 20, a placement platform 100 is mounted on one side of the workbench 30, and multiple clamping components 200 and multiple edge pulling components 300 are mounted on the other side of the workbench 30. A controller 40 is mounted on one side of the frame 20 for electrically controlling the multiple clamping components 200 and multiple edge pulling components 300. The length direction of the placement platform 100 is consistent with the length direction of the workbench 30.

[0035] The placement platform 100 is used to place the VIP board 10, which facilitates the clamping component 200 and the edge-pulling component 300 to pull the edges of the VIP board 10.

[0036] Reference Figure 1 Multiple clamping components 200 are evenly distributed on the same side of the placement platform 100, and adjacent clamping components 200 are spaced apart. The clamping components 200 are used to clamp the side film bag 11 on one side of the VIP board 10 so as to generate sufficient friction during the edge pulling process to provide pulling force for the side film bag 11 to pull out the suction edge.

[0037] Specifically, multiple clamping components 200 are evenly arranged along the length of the placement platform 100.

[0038] After vacuuming, the excess part of the membrane bag (i.e., barrier membrane) will attract the edge at the core material edge. When the edge is pulled, the entire membrane bag is sealed and air will not re-enter the membrane bag. The attracting edge is equivalent to a fold. To straighten the fold, the membrane bag will slide along the side as its side membrane bag 11 is pulled until it is flattened.

[0039] The edge-pulling process involves pulling the side film bag 11 to overcome the friction between the film bag and the core material under atmospheric pressure, as well as the vacuum adsorption force at the edge suction point. If the pulling force is greater than the combined force of the friction and vacuum forces, the suction edge can be pulled out. Theoretically, the clamping components 200 are distributed without gaps along the side film bag 11, resulting in the minimum and most uniform force on the film bag, with the force per unit width equal to the resultant force per unit width. However, the suction edges on the VIP plate 10 are inconsistent, and the pulling lengths at adjacent positions may differ. The pulling forces between adjacent edge-pulling components 300 will affect each other, actually reducing the pulling force. To pull out the suction edge, the side film bag 11 may be subjected to a greater overall pulling force, which is not conducive to pulling out the suction edge. Therefore, the edge-pulling components 300 and the clamping components 200 adopt a single-sided linear array, and adjacent clamping components 200 are spaced apart. In this embodiment, the width of the clamping components 200 and the width of the gap are evenly distributed in a 2:1 ratio. The width of the clamping components 200 is 50mm, meaning the width of the gap is 25mm. The reason for the spacing is that the edge suction is inconsistent. Multiple clamping components 200 must be set to ensure that the pull-out length of each clamping component 200 can be different. If each clamping component 200 is close together, the pulling force between adjacent clamping components 200 will be affected when pulling the edge. For example, if one clamping component 200 only pulls out 1mm, the adjacent clamping component 200 needs to pull out 10mm. When two clamping components 200 pull out to 1mm at the same time, the first one stops, and the second one needs to pull out 9mm to pull out completely. During the pulling process of the second clamping component 200, the film bag clamped by the first clamping component 200 will pull the film bag next to it, causing the film bag clamped by the second clamping component 200 to be unable to be pulled out. Therefore, in order to reduce this impact, gaps need to be left between the clamping components 200 to achieve different pull-out lengths, so that the side film bags 11 are subjected to uniform force and the influence of the pull-out stroke variation between them is reduced.

[0040] Reference Figure 1 Multiple edge-pulling components 300 are located on the same side of the placement platform 100, and each of the multiple edge-pulling components 300 corresponds to a multiple clamping component 200. The clamping component 200 is connected to the edge-pulling component 300, and the edge-pulling component 300 is used to provide pulling force to the clamping component 200 to pull out the suction edge.

[0041] Specifically, multiple edge-pulling components 300 are evenly arranged along the length of the placement platform 100.

[0042] The reason why the multiple clamping components 200 and multiple edge-pulling components 300 in this embodiment are only set on the same side of the placement platform 100, and not on both sides of the placement platform 100, is that when both sides are pulled at the same time, the side film bags 11 on both sides will pull each other when subjected to force. Since the degree of edge suction is different at different parts of the VIP board 10, the side that is pulled out first will share some force with the other side that is not fully pulled out, resulting in uneven force on the side film bags 11 on both sides. Although the side that is pulled out first will continue to maintain the tension to clamp the side, the other side that is not fully pulled out will continue to pull, which will cause the side film bag 11 on the side that is pulled out first to deform, thereby damaging the side film bag 11. Therefore, this embodiment uses single-sided edge pulling to achieve edge pulling of the side film bag 11.

[0043] Reference Figure 2 and Figure 4 In this embodiment, the clamping assembly 200 includes a mounting bracket 210, a first telescopic member 220, an upper clamping end 230, and a lower clamping end 240.

[0044] The mounting bracket 210 is located on one side of the placement platform 100. A first telescopic member 220 is installed on the top of the mounting bracket 210. The telescopic end of the first telescopic member 220 extends into the mounting bracket 210 and is connected to the upper clamping end 230. A lower clamping end 240 located directly below the upper clamping end 230 is installed at the bottom of the mounting bracket 210.

[0045] Specifically, the mounting frame 210 is slidably mounted on the workbench 30, and the first telescopic member 220 is vertically mounted on the top of the mounting frame 210. The first telescopic member 220 can be a cylinder, an electric cylinder, or a hydraulic cylinder. In this embodiment, the first telescopic member 220 is preferably a cylinder. The telescopic end of the first telescopic member 220 passes through the top of the mounting frame 210 and extends into the mounting frame 210. The telescopic end of the first telescopic member 220 is slidably connected to the mounting frame 210. The upper clamping end 230 and the lower clamping end 240 are arranged opposite to each other to ensure that the tension on the side film bag 11 is evenly distributed. The side film bag 11 of the VIP plate 10 can extend into the space between the upper clamping end 230 and the lower clamping end 240.

[0046] During the edge pulling operation, the side film bag 11 of the VIP plate 10 is first placed between the upper clamping end 230 and the lower clamping end 240. The controller 40 controls the first telescopic member 220 to press down, and the upper clamping end 230 presses the side film bag 11 tightly onto the lower clamping end 240, providing sufficient pressure to ensure that sufficient friction is generated during the edge pulling process to provide pulling force for the side film bag 11 to pull out the suction edge.

[0047] Reference Figure 2 and Figure 4, in this embodiment, the mounting bracket 210 is arranged in a "C" - shaped structure, and the opening of the mounting bracket 210 faces the placing platform 100.

[0048] Specifically, by setting the opening of the mounting bracket 210 to face the placing platform 100, the side film bags 11 on the same side of the VIP board 10 can extend between the upper clamping end 230 and the lower clamping end 240.

[0049] Refer to Figure 2 and Figure 4 , in this embodiment, the ends of the upper clamping end 230 and the lower clamping end 240 close to the placing platform 100 are arranged horizontally, and the ends of the upper clamping end 230 and the lower clamping end 240 far from the placing platform 100 are arranged in a wavy shape.

[0050] Specifically, by arranging the front ends of the upper clamping end 230 and the lower clamping end 240 horizontally, the force on the side film bags 11 is more uniform. By arranging the rear ends of the upper clamping end 230 and the lower clamping end 240 in a wavy shape, when the upper clamping end 230 and the lower clamping end 240 clamp the side film bags 11, a greater frictional force is generated to ensure that the side film bags 11 do not slip during the edge - pulling process. The contact positions between the upper clamping end 230 and the lower clamping end 240 and the side film bags 11 all adopt rounded - corner transitions, making the force on the side film bags 11 uniform and avoiding stress concentration points on the side film bags 11.

[0051] Refer to Figure 2 and Figure 4 , in this embodiment, the upper clamping end 230 and the lower clamping end 240 are made of soft polyurethane material.

[0052] Specifically, during the edge - pulling process, the soft polyurethane deforms to distribute the pulling force, making the force - bearing area of the side film bags 11 larger, reducing the local strain increase and plastic deformation caused by concentrated force on the side film bags 11, and thus reducing the risk of air leakage.

[0053] Refer to Figures 1 to 4 , in this embodiment, the edge - pulling assembly 300 includes a second telescopic member 310 and a sliding member 320;

[0054] The output end of the second telescopic member 310 is connected to the side of the mounting bracket 210背离开口的一侧 (it seems there is a wrong expression here, maybe it should be "opposite to the opening side"), and the sliding member 320 is connected to the bottom of the mounting bracket 210.

[0055] Specifically, the second telescopic member 310 is installed on the side of the workbench 30 away from the placement platform 100, and the mounting bracket 210 is located on the side of the workbench 30 close to the placement platform 100. The second telescopic member 310 is horizontally arranged and can be a cylinder, electric cylinder, hydraulic cylinder, or linear motor. In this embodiment, the first telescopic member 220 is preferably a linear motor. The current of the linear motor is proportional to the tension. By controlling the current of the linear motor, the tension can be precisely controlled, providing a stable pull-out speed for the clamping assembly 200, keeping the tension within the plastic deformation range, maintaining the barrier film performance, and ensuring product quality.

[0056] Reference Figure 2 The edge-pulling assembly 300 also includes a fixing plate 330 mounted on the workbench 30. The fixing plate 330 is L-shaped and includes a horizontal part and a vertical part. The horizontal part of the fixing plate 330 is connected to the workbench 30. The second telescopic member 310 is mounted on the vertical part of the fixing plate 330, and the telescopic end of the second telescopic member 310 passes through the vertical part of the fixing plate 330 and is connected to the side of the mounting bracket 210 opposite to the opening. The telescopic end of the second telescopic member 310 is slidably connected to the vertical part of the fixing plate 330. The sliding member 320 is located between the placement platform 100 and the fixing plate 330.

[0057] After the upper clamping end 230 and the lower clamping end 240 clamp the side film bag 11, the second telescopic member 310 provides power to pull the mounting frame 210, thereby pulling the side film bag 11 and pulling out the suction edge.

[0058] Reference Figure 2 and Figure 4 In this embodiment, the slider 320 includes a linear slider 321 and a guide rail 322;

[0059] The linear slider 321 is connected to the bottom of the mounting bracket 210, and the linear slider 321 slides in conjunction with the guide rail 322.

[0060] Specifically, the guide rail 322 is installed on the workbench 30 and is located between the placement platform 100 and the fixed plate 330; the bottom of the mounting bracket 210 is connected to a linear slider 321. Through the sliding cooperation between the linear slider 321 and the guide rail 322, the mounting bracket 210 moves stably when the second telescopic member 310 pulls the mounting bracket 210.

[0061] Reference Figure 2 and Figure 4 In this embodiment, a boss 110 is provided on the side edge of the placement platform 100 near the mounting bracket 210.

[0062] Specifically, during the edge pulling process, the boss 110 blocks the side of the VIP plate 10 to prevent relative displacement when it is under tension; the height of the boss 110 is 3-8mm, and the upper part of the side away from the mounting bracket 210 is rounded. Preferably, the height of the boss 110 is 5mm, and the top surface of the boss 110 can be flush with the front horizontal surface of the lower clamping end 240; and during the edge pulling process, pressure can be applied manually to the top surface of the VIP plate 10 to further prevent relative displacement of the VIP plate 10.

[0063] Reference Figures 1 to 4 In this embodiment, the mechanical properties of the barrier film are determined based on the tensile mechanical property test of the barrier film bag as follows:

[0064] 1. The barrier film bag has no obvious yield point;

[0065] 2. The tensile elongation of the barrier film bag is >40%;

[0066] 3. From the stress-strain curve, it can be seen that when the tensile force is about 50% of the breaking tensile force, the membrane bag gradually changes from elastic deformation to plastic deformation, and the membrane bag begins to stretch and become thinner.

[0067] The results above show that when the edge is pulled out, the force per unit width at the clamping point of the film bag should be controlled at about 50% of the breaking tensile force to ensure that the film bag remains in elastic deformation without being damaged during the edge pulling process.

[0068] Before the VIP plate 10 is pulled along the edge, the breaking tensile force of the film bag is input into the controller 40. Based on the tensile mechanical properties of the barrier film bag, the controller 40 controls the tension of the second telescopic component 310 to not exceed 50% of the breaking tensile force. A manual mode can be set to manually increase the tension for special edge-pulling requirements. The edge-pulling process is divided into two stages:

[0069] Phase 1: Pull-out start, controller 40 controls the second telescopic component 310 to pull out the edge at a constant speed, and provides a maximum pulling force of 45% of the breaking pulling force according to the pulling force set current threshold, with a speed of 5-10mm / s. As the second telescopic component 310 is pulled out, the current gradually increases due to load changes. When the current reaches the threshold, the control mode switches to Phase 2.

[0070] Phase Two: Current threshold adjustment, providing a maximum tensile force of 50% of the breaking tensile force, the tensile force gradually increases. According to the current closed-loop control of the tensile force, when the tensile force of one of the second telescopic components 310 reaches the threshold, the second telescopic component 310 maintains the tensile force, while the tensile force of the adjacent second telescopic component 310 decreases due to the continued increase in the pull-out edge stroke. The aforementioned second telescopic component 310 will maintain the tensile force to continue pulling out, so as to reduce the mutual influence of the tensile forces of the adjacent second telescopic components 310, thereby achieving uniform force and low-speed pulling out, reducing damage to the film bag. When the tensile force of all second telescopic components 310 reaches the threshold, and the position of the telescopic end of the second telescopic component 310 does not change, then all the edges are pulled out, the upper clamping end 230 and the lower clamping end 240 are released, the second telescopic components 310 are reset, and the equipment enters the next cycle (that is, the edges of the film bags on the other sides of the VIP plate are pulled out one by one).

[0071] In this embodiment, the second telescopic member 310 is started simultaneously, and the tension of the linear motor is controlled by the current, so the current of each linear motor is controlled.

[0072] When the tension of one of the second telescopic members 310 reaches the predetermined tension, and the length of the film bag pulled out by the adjacent second telescopic member 310 is greater than the length of the film bag pulled out by the aforementioned second telescopic member 310 (because the degree of edge suction is different in different places, the length of the film bag pulled out when the edge suction is fully pulled out is also different in different places), since the film bags are connected together, the film bag pulled out by the aforementioned second telescopic member 310 will pull the film bag pulled out by the adjacent second telescopic member 310. It is equivalent to the tension of the adjacent second telescopic member 310 not only being applied to the film bag, but also sharing part of the force with the aforementioned second telescopic member 310. Therefore, the tension of the aforementioned second telescopic member 310 will decrease. In order to ensure that the adjacent second telescopic member 310 has enough tension to apply to the edge suction area, the tension of the aforementioned second telescopic member 310 must be maintained at the set value to ensure that there is enough force to pull out the edge suction.

[0073] For example, assuming we set the value to 100N, one of the aforementioned second telescopic members 310 pulls the film bag out by 1mm and then reaches 100N (meaning the film bag only needs to be pulled out 1mm to fully extend the suction edge at that point). The adjacent second telescopic member 310 only applies 50N when it pulls the film bag out 1mm (meaning the film bag at that point is not yet fully extended). The adjacent second telescopic member 310 will continue to pull the film bag until the tension reaches 100N. However, if the adjacent second telescopic member 310 continues to pull the film bag, it will also pull the film bag at the aforementioned second telescopic member 310 outwards. This means the tension from the adjacent second telescopic member 310 is not only applied to the film bag but also to the aforementioned second telescopic member 310. The 0 also diverts some of the pulling force. Assuming that one of the aforementioned second telescopic components 310 remains stationary, pulling 1mm only requires 100N. The adjacent second telescopic component 310 provides some pulling force to the aforementioned second telescopic component 310, so the pulling force of the aforementioned second telescopic component 310 is no longer 100N, but less than 100N. At this time, the aforementioned second telescopic component 310 needs to continue to pull out, maintaining 100N, so that the pulling force diverted to the aforementioned second telescopic component 310 by the adjacent second telescopic component 310 is reduced, in order to ensure that the adjacent second telescopic component 310 can reach the pulled-out state and ensure that the adjacent second telescopic component 310 has enough pulling force to pull out the suction edge.

[0074] This means that the edge-pulling stroke of each second telescopic component 310 is different. It is possible that one of the second telescopic components 310 will stop pulling the edge once it is fully pulled and maintain the set value, while the other second telescopic components 310 that have not yet been fully pulled will continue to pull the edge. The operator does not care about the edge-pulling stroke. As long as each second telescopic component 310 reaches the set value of the tension, the edge-pulling is considered to be completed. This is because the edge-pulling is divided into two stages. The first stage is to pull out the film bag, and the second stage is to maintain the tension. The holding stage is equivalent to compensating for the film bag being pulled out at the adjacent position.

[0075] Working principle: In use, the VIP board 10 that needs to be edge-pulled is placed on the placement platform 100. The side film bag 11 on one side of the VIP board 10 is inserted between the upper clamping end 230 and the lower clamping end 240. The controller 40 controls the first telescopic member 220 to press down, and the upper clamping end 230 presses the side film bag 11 tightly onto the lower clamping end 240, providing sufficient pressure. Then, the second telescopic member 310 provides power to pull the mounting frame 210. The mounting frame 210 moves along the guide rail 322 via the linear slider 321. This pulls the side film bag 11, thereby pulling out the suction edge. After the suction edge on one side of the VIP plate 10 is pulled out, the upper clamping end 230 and the lower clamping end 240 are opened by the first telescopic member 220, releasing the side film bag 11 on that side. The second telescopic member 310 pushes the mounting frame 210 to reset, and then the side film bags 11 on the other sides of the VIP plate 10 are pulled out one by one to complete the suction edge pulling out of the VIP plate 10. The force is controlled within the plastic deformation by the second telescopic member 310 to maintain the performance of the barrier film and ensure product quality.

[0076] This invention enables control of the tension during the edge-pulling process, keeping the tension within the range of plastic deformation. This ensures that the product has sufficient plastic reserve, reduces the scrap rate of products in subsequent processes, and prevents the barrier film from thinning due to plastic deformation, thus guaranteeing its barrier performance. At the same time, it avoids the problem of uncontrollable tension and pulling speed by operators, reducing the labor intensity of operators.
