Description

Technical Field

[0001] This invention relates to the field of ultrathin ceramic electrode film manufacturing technology, and more specifically to an ultrathin ceramic film peeling and stacking system. Background Technology

[0002] Multilayer ceramic capacitors (MLCCs) are the most widely used electronic components, found in almost all electronic products. A single mobile phone contains over 1500 MLCCs, and a new energy vehicle contains over 20,000. Due to their large usage and wide applications, MLCCs are often referred to as "industrial electronic rice." With the miniaturization and increasing intelligence of electronic products, the size of MLCCs has become a significant challenge, making miniaturization a key focus of technological research and development for various manufacturers. After miniaturization, MLCCs still need to maximize their capacitance. Stacking as many layers as possible within a limited space to increase product capacity has become a key technological focus. Currently, high-end MLCC products stack over 1000 thin films on a 0.5mm thickness. To achieve this, the ceramic electrode film must be made as thin as possible. When the ceramic electrode film is less than 1μm, the key technical challenge is how to completely and without damage peel the less than 1μm ceramic electrode film from the PET plastic film.

[0003] In existing technologies, since it is not necessary to make the ceramic electrode film very thin, the peeling process is not a technical challenge in the stacking process for thicker ceramic electrode films, such as... Figure 1 As shown, a sharp-angle peeling process is typically used to stretch the PET plastic film, making it relatively easy to detach the ceramic electrode film. However, with the increasing demand for miniaturization, when the ceramic electrode film is ultra-thin, the sharp-angle peeling process cannot completely and without damage remove the ceramic electrode film.

[0004] In addition, such as Figure 2 and Figure 3 As shown, the peeled ceramic electrode films are typically stacked using a flatbed direct-pressing process, similar to applying a ceramic protective cover to a mobile phone screen. Direct pressing results in numerous air bubbles across the entire screen. As the ceramic electrode films become thinner and the number of layers increases, the accumulation of air bubbles generated by the traditional direct-pressing process severely impacts subsequent processes and product quality. Summary of the Invention

[0005] The purpose of this invention is to provide an ultrathin ceramic film peeling and stacking system to solve the problem of thinner ceramic films than 1 The technical challenge of non-destructive peeling and stacking of ceramic electrode films.

[0006] To address the aforementioned problems, this invention discloses an ultrathin ceramic membrane peeling and stacking system. The ultrathin ceramic electrode membrane peeling and stacking system is used to peel and stack ultrathin ceramic electrode membranes.

The other end of each gas pipeline is flush with the arc surface of the peeling and stacking roller shaft. The gas delivery device draws gas from the multiple gas pipelines, causing the peeling and stacking roller shaft to exert a detachment adsorption force on the ceramic electrode membrane or the ceramic protective cover.

[0013] The stacking support platform is located below the peeling and stacking roller shaft. The peeling and stacking roller shaft moves downward in the vertical direction to the stacking support platform.

[0018] Optionally, the mesh layer thickness is 100. -300 The adsorption layer has a thickness of 80 mm. -200 The mesh layer is a metal crimped wire mesh structure, which is formed by multiple rolled wavy metal wires overlapping horizontally and vertically, and the mesh aperture of the mesh layer is 80-400 mesh.

[0019] Optionally, the peeling and stacking roller shaft rotates counterclockwise along the axis. When the peeling and stacking roller shaft lifts the ceramic electrode film material, the rotation direction of the peeling and stacking roller shaft is the same as the conveying direction of the ceramic electrode film material. When the peeling and stacking roller shaft lifts the ceramic protective cover sheet material, the rotation direction of the peeling and stacking roller shaft is the same as the conveying direction of the ceramic protective cover sheet material.

[0020] Optionally, the wrap angle formed when the peeling and stacking rollers lift the ceramic electrode film material is 15°. o -30 o The wrap angle formed when the peeling and stacking rollers lift the ceramic protective cover strip is 15 degrees. o -30 oThe central angle of the adsorption section on the peeling stacking roller is 15 degrees. o -30 o .

[0021] Optionally, the stacked support platform is mounted on a conveyor rail, and after the ceramic electrode film and the ceramic protective cover are stacked on the stacked support platform, they are removed by the conveyor rail.

[0022] Optionally, the ultra-thin ceramic electrode film peeling and stacking system further includes a ceramic electrode film strip reel, a ceramic electrode film strip tension roller, a ceramic electrode film cutter, a ceramic electrode film strip power conveyor shaft, and a ceramic electrode film strip recovery reel. The ceramic electrode film strip reel extends from the ceramic electrode film strip, which is conveyed to the ceramic electrode film strip power conveyor shaft via the ceramic electrode film strip tension roller. The ceramic electrode film strip is then cut by the ceramic electrode film cutter, conveyed to the ceramic electrode film corner peeling device, and finally recovered by the ceramic electrode film strip recovery reel.

[0023] Optionally, the ultra-thin ceramic electrode film peeling and stacking system further includes a ceramic protective cover strip reel, a ceramic protective cover strip tension roller, a ceramic protective cover cutter, a ceramic protective cover strip power conveyor shaft, and a ceramic protective cover strip recycling reel;

[0024] The ceramic protective cover sheet material strip reel extends out of the ceramic protective cover sheet material strip, which is then conveyed to the ceramic protective cover sheet material strip power conveyor shaft via the ceramic protective cover sheet material strip tension roller. The ceramic protective cover sheet is then cut by the ceramic protective cover sheet cutter, conveyed to the ceramic protective cover sheet corner peeling device, and finally recycled by the ceramic protective cover sheet material strip recycling reel.

[0025] Optionally, it also includes a servo motor and a moving platform, wherein the stripping and stacking roller is driven to rotate by the servo motor; the stripping and stacking roller is mounted on the moving platform, and the moving platform drives the stripping and stacking roller to reciprocate in the horizontal and vertical directions.

[0026] Beneficial effects:

[0027] This invention discloses an ultra-thin ceramic diaphragm peeling and stacking system. By setting the corner peeling device to two peeling rollers, the material strip passes around the two peeling rollers, and the peeling and stacking roller shaft moves upward, pushing the material strip between the two peeling rollers upward to form a corner. At the same time, the gas conveying device draws gas from multiple gas pipelines, so that the ceramic electrode diaphragm in the corner generates a separation force from the peeling and stacking roller shaft. An approximately vacuum area is formed between the peeling and stacking roller shaft and the ceramic electrode diaphragm. Under the rolling of the peeling and stacking roller shaft and the conveying of the ceramic electrode diaphragm, the ceramic electrode diaphragm is completely and undamagedly peeled off from the material strip.

[0028] The stripping and stacking roller moves downwards to the stacking support platform. Through rolling, one side of the ceramic electrode film or ceramic protective cover is first pressed onto the stacking support platform. Then, as the stripping and stacking roller rolls, the entire ceramic electrode film or ceramic protective cover is stacked onto the stacking support platform. This avoids the generation of air bubbles in the ceramic electrode film or ceramic protective cover during the stacking process. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0045] The technical solution of the present invention will be further illustrated below through specific embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The content of the embodiments does not constitute a limitation on the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] like Figures 4-11 As shown, the present invention discloses an ultrathin ceramic film peeling and stacking system. The ultrathin ceramic electrode film peeling and stacking system is used to peel and stack ultrathin ceramic electrode films. The ultrathin ceramic electrode film peeling and stacking system includes a corner peeling device, a peeling and stacking roller 1, a film adsorption mechanism, and a stacking support platform 2.

[0047] The corner peeling device includes two parallel peeling rollers 3, spaced apart. The spacing and relative position of the two peeling rollers 3 can be set according to actual needs. Two corner peeling devices are provided: one for peeling the ceramic electrode film corner and the other for peeling the ceramic protective cover corner.

[0048] The ceramic electrode diaphragm corner peeling device and the ceramic protective cover corner peeling device are arranged at intervals, and the specific interval can be set according to actual needs. The ceramic electrode diaphragm strip 4, carrying the ceramic electrode diaphragm, is wound around and conveyed through the two peeling rollers 3 of the ceramic electrode diaphragm corner peeling device. The ceramic protective cover strip 5, carrying the ceramic protective cover, is wound around and conveyed through the two peeling rollers 3 of the ceramic protective cover corner peeling device. Here, "winding" refers to wrapping around the peeling rollers 3, not multiple turns. The diameter of the peeling rollers 3 is not specifically limited in this application; the ease of peeling the ceramic electrode diaphragm and ceramic protective cover is not directly related to the diameter of the peeling rollers 3, and the diameter of the peeling rollers 3 can be set according to actual needs.

[0049] The peeling and stacking roller 1 is located below the ceramic electrode film wrapping angle peeling device. The peeling and stacking roller 1 can rotate along the axis and can reciprocate in the horizontal and vertical directions respectively.

[0050] After the peeling and stacking roller 1 moves horizontally and vertically, it can lift the ceramic electrode film strip 4 between the two peeling rollers 3 of the ceramic electrode film corner peeling device. The film adsorption mechanism adsorbs the ceramic electrode film, and the peeling and stacking roller 1 rotates along the axis to detach the ceramic electrode film from the ceramic electrode film strip 4. After the peeling and stacking roller 1 moves horizontally and vertically, it can lift the ceramic protective cover strip 5 between the two peeling rollers 3 of the ceramic protective cover corner peeling device. The film adsorption mechanism adsorbs the ceramic protective cover, and the peeling and stacking roller 1 rotates along the axis to detach the ceramic protective cover from the ceramic protective cover strip 5.

[0051] The membrane adsorption mechanism includes a gas delivery device and multiple gas pipelines. The gas delivery device can be a vacuum pump, a suction pump, or a suction machine. The gas delivery device is located outside the peeling and stacking roller 1, while the multiple gas pipelines are located inside the peeling and stacking roller 1. One end of each gas pipeline is connected to the air inlet of the gas delivery device, and the other end extends into the peeling and stacking roller 1, passing through the arc surface of the peeling and stacking roller 1, i.e., connecting to the adsorption surface of the peeling and stacking roller 1. The ports of the multiple gas pipelines are flush with the arc surface of the peeling and stacking roller 1. The gas delivery device draws gas from the multiple gas pipelines, removing air between the peeling and stacking roller 1 and the ceramic electrode membrane or ceramic protective cover, creating a near-vacuum region. This causes the peeling and stacking roller 1 to exert a detachment force on the ceramic electrode membrane or ceramic protective cover. Then, as the peeling and stacking roller 1 rotates, the ceramic electrode membrane or ceramic protective cover can be easily peeled off.

[0052] Specifically, such as Figures 9-10 As shown, the peeling stacking roller 1 includes an adsorption section 22 and a non-adsorption section 23 along the circumferential direction. The adsorption section 22 includes a shaft body 11, a mesh layer 12, and an adsorption layer 13. The mesh layer 12 is disposed on the outside of the shaft body 11, and the adsorption layer 13 is disposed on the outside of the mesh layer 12.

[0053] like Figure 11 As shown, the multiple gas pipelines include transfer pipelines, multiple main pipelines 19, multiple branch pipelines 20, and multiple adsorption holes 21. The main pipeline 19 is a tubular structure open at one end and closed at the other. The shaft body 11 has multiple blind holes for accommodating the main pipelines 19. These blind holes extend axially along the peeling and stacking roller shaft 1 and are staggered radially and circumferentially along the peeling and stacking roller shaft 1. In this application, the blind holes can be used directly as the main pipelines 19, or pipelines can be placed within the blind holes to serve as the main pipelines 19.

[0054] The transfer line is used to connect multiple main lines 19 together to the gas delivery equipment. One end of the transfer line is connected to the inlet of the gas delivery equipment, and the other end is connected to the open end of the multiple main lines 19.

[0055] The shaft body 11 has multiple through-hole structures radially arranged to accommodate branch pipes 20. One end of each through-hole structure connects to a blind hole, and the other end connects to the side wall of the shaft body 11. The side wall of each main pipe 19 connects to one end of each of the multiple branch pipes 20, and the other ends of each of the multiple branch pipes 20 connect to the side wall of the shaft body 11. In this application, the through-hole structure can be used directly as the branch pipe 20, or a pipe can be set in the through-hole structure as the branch pipe 20.

[0056] Multiple adsorption pores 21 are disposed on the adsorption layer and penetrate the adsorption layer. The diameter of the adsorption pores 21 is between 0.3 mm and 0.6 mm.

[0057] Since the grid layer 12 itself has multiple grids and is not a closed structure, the grid layer 12 does not need to be equipped with pipelines, and gas can also flow through the grid.

[0058] Specifically, when it is necessary to peel off the ceramic electrode film, the peeling stacking roller 1 moves horizontally to below the ceramic electrode film corner peeling device, and then moves upward to lift the ceramic electrode film strip 4 between the two peeling rollers 3 of the ceramic electrode film corner peeling device. A corner is formed between the peeling stacking roller 1 and the ceramic electrode film strip. At this time, the gas conveying equipment starts to evacuate the air between the peeling stacking roller 1 and the ceramic electrode film strip 4, so that the air between the peeling stacking roller 1 and the ceramic electrode film strip 4 is discharged, forming a near-vacuum area. This makes the atmospheric pressure between the peeling stacking roller 1 and the ceramic electrode film strip 4 lower than the external atmospheric pressure, thereby generating a peeling adsorption force. At this time, as the peeling stacking roller 1 continues to rotate, the ceramic electrode film strip 4 continues to be conveyed. Under the action of the peeling adsorption force and the pulling force generated by the rotation, the ceramic electrode film detaches from the ceramic electrode film strip 4 and is adsorbed onto the peeling stacking roller 1. Similarly, the ceramic protective cover detaches from the ceramic protective cover strip 5 using the same principle and is adsorbed onto the peeling stacking roller 1.

[0059] Preferably, the stacking support platform 2 is located below the peeling and stacking roller 1. The peeling and stacking roller 1 moves vertically downward to the upper surface of the stacking support platform 2. At this time, the gas conveying equipment stops pumping air, and the ceramic electrode film or ceramic protective cover is no longer subject to peeling adsorption force. Under high temperature conditions, relying on the action of the PVB additive (adhesive) inside the film, the peeling and stacking roller 1 rotates along the axis to stack the ceramic electrode film or ceramic protective cover onto the upper surface of the stacking support platform 2.

[0060] In this application, the peeling and stacking roller 1 alternately peels and stacks the ceramic electrode film and the ceramic protective cover, so that the ceramic electrode film and the ceramic protective cover on the stacking support platform 2 are also stacked alternately.

[0061] Preferably, the peeling stacking roller 1 rotates counterclockwise along the axis. When the peeling stacking roller 1 lifts the ceramic electrode film material, the rotation direction of the peeling stacking roller 1 is the same as the conveying direction of the ceramic electrode film material. Setting the rotation direction of the peeling stacking roller 1 and the conveying direction of the ceramic electrode film material to be the same is beneficial to the peeling of the ceramic electrode film, making it easier and more complete to peel the ceramic electrode film.

[0062] After the ceramic electrode film or ceramic protective cover is stacked on the stacking support platform 2, the peeling and stacking roller 1 rotates clockwise to reset and perform the next peeling and stacking process, and so on in a reciprocating cycle.

[0063] Furthermore, such as Figure 5 As shown, the wrap angle formed when the peeling and stacking roller 1 lifts the ceramic electrode film strip is 15°. o -30 o The wrap angle formed when the peeling stacking roller 1 lifts the ceramic protective cover strip is 15 degrees. o -30 o The central angle of the adsorption section 22 on the peeling stacking roller 1 is 15 degrees. o -30 o The specific wrap angle can be determined based on actual usage requirements. When peeling requires greater adsorption force, the wrap angle can be increased; when peeling requires less adsorption force, the wrap angle can be decreased.

[0064] Mesh layer 12 has a thickness of 100. -300 The adsorption layer 13 has a thickness of 80 mm. -200 The mesh layer 12 is specifically a crimped metal mesh structure, formed by multiple rolled, wavy metal wires interlocked horizontally and vertically. The mesh size of the mesh layer 12 is 80-400 mesh. Figure 8 and Figure 9 As shown, the interlacing of multiple metal wires creates regular protrusions and recesses on the mesh layer 12. This transforms the contact between the peeling and stacking roller 1 and the stacking support platform 2 from a single line to multiple small planes, resulting in more uniform pressing of the ceramic electrode film or ceramic protective cover by the peeling and stacking roller 1. Each part of the ceramic electrode film or ceramic protective cover can adhere to the stacking support platform 2, allowing for more thorough expulsion of air from under the ceramic electrode film or ceramic protective cover, leading to a neater stacking of the ceramic electrode film and ceramic protective cover. In other embodiments, both the mesh layer 12 and the adsorption layer 13 can be made of metal or non-metal materials.

[0065] Due to the grid layer 12, the original entire adsorption layer 13 is divided into multiple small adsorption units, with each small grid forming an adsorption unit. Each adsorption unit has multiple adsorption holes 21. The number of adsorption holes 21 on the adsorption layer 13 is greater than the number of branch pipes 20 in the shaft body 11, while the number of branch pipes 20 in the shaft body 11 is greater than the number of main pipes 19. Due to the uniform peeling adsorption force, the ceramic electrode film or ceramic protective cover can be more easily peeled off from the strip, and it is not easily damaged during the peeling process.

[0066] like Figure 7 As shown, when the peeling and stacking roller 1 stacks ceramic electrode films or ceramic protective covers onto the stacking support platform 2, the peeling and stacking roller 1 and the stacking support platform 2 make line contact, forming a stacking line. Normally, two points in the stacking line determine a straight line, making it easy for air bubbles to appear in the stacked layers during the stacking process, affecting the quality of the stacked layers. However, in this application, because the peeling and stacking roller 1 has an uneven structure on its surface, when the peeling and stacking roller 1 makes line contact with the stacking support platform 2, there will be multiple contact points on the stacking line. During the process of the peeling and stacking roller 1 rolling and stacking the ceramic electrode films or ceramic protective covers from one side to the other, air bubbles in the stacked layers will be squeezed out, avoiding the formation of air bubbles in the stacked layers, making the stacked layers more uniform and with better hardness.

[0067] Optionally, the grid in grid layer 12 is a rectangular structure. The purpose of setting grid layer 12 is to increase the number of contact points on the contact line between the peeling stacking roller 1 and the stacking support platform 2; therefore, the grid in grid layer 12 can be square or rectangular. Figure 8 As shown, this application adopts a square structure grid, and tens of thousands of contact points are formed on the stacking line formed by the contact between the peeling stacking roller 1 and the stacking support platform 2.

[0068] Preferably, the stacking support platform 2 is mounted on a conveyor rail. After the ceramic electrode films and ceramic protective covers are stacked on the stacking support platform 2, they are removed by the conveyor rail. Then, the stacked layers are unloaded from the stacking support platform 2, and the next stacking operation begins. The conveyor rail can be moved manually or by a motor to drive the stacking support platform 2.

[0069] Specifically, the ultra-thin ceramic electrode diaphragm peeling and stacking system also includes a ceramic electrode diaphragm strip reel 6, a ceramic electrode diaphragm strip tension roller 7, a ceramic electrode diaphragm cutter 8, a ceramic electrode diaphragm strip power conveyor shaft 9, and a ceramic electrode diaphragm strip recovery reel 10. Multiple tension rollers 7 and two power conveyor shafts 9 are provided. The ceramic electrode diaphragm strip extends from the ceramic electrode diaphragm reel 6, is conveyed via the tension rollers 7 to the power conveyor shaft 9, where it is cut by the cutter 8, then conveyed to the corner peeling device, subsequently to another power conveyor shaft 9 and tension roller 7, and finally recovered by the recovery reel 10.

[0070] Specifically, the ultra-thin ceramic electrode film peeling and stacking system also includes a ceramic protective cover sheet material roll 14, a ceramic protective cover sheet material tension roller 15, a ceramic protective cover sheet cutter 16, a ceramic protective cover sheet material power conveyor shaft 17, and a ceramic protective cover sheet material recycling roll 18. Multiple ceramic protective cover sheet material tension rollers 15 and two ceramic protective cover sheet material power conveyor shafts 17 are provided.

[0071] The ceramic protective cover sheet material reel 14 extends out of the ceramic protective cover sheet material. The ceramic protective cover sheet material is conveyed to the ceramic protective cover sheet material power conveyor shaft 17 via the ceramic protective cover sheet material tension roller 15, and then cut by the ceramic protective cover sheet cutter 16. It is then conveyed to the ceramic protective cover sheet corner peeling device, and then to another ceramic protective cover sheet material power conveyor shaft 17 and ceramic protective cover sheet material tension roller 15, and finally recycled by the ceramic protective cover sheet material recycling reel 18.

[0072] Furthermore, the ultrathin ceramic electrode film peeling and stacking system also includes a servo motor. The output shaft of the servo motor is fixedly connected to the peeling and stacking roller shaft 1, which is driven to rotate by the servo motor. The servo motor can precisely control the rotation speed of the peeling and stacking roller shaft 1, and can be set according to the peeling and stacking requirements to ensure that the ceramic electrode film or ceramic protective cover can be completely peeled off and that the stacking can be carried out smoothly.

[0073] Furthermore, the ultrathin ceramic electrode film peeling and stacking system also includes a moving platform. The peeling and stacking roller 1 is mounted on the moving platform, and the moving platform drives the peeling and stacking roller 1 to reciprocate in the horizontal and vertical directions. The moving platform is also driven by a servo motor to ensure the accurate positioning of the peeling and stacking roller 1.

Those skilled in the art should understand that any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention fall within the scope of protection and disclosure of the present invention.
