Description

Technical Field

[0001] This application relates to equipment for manufacturing inductors, and more particularly to an inductor stacking apparatus and stacking method. Background Technology

[0002] Currently, multilayer chip inductors are a widely used micro electronic component. Their manufacturing process is complex and mainly includes the following steps: sanding → casting → film cutting → drilling → printing → lamination → lamination → cutting → glue removal → firing → chamfering → end sealing → firing → deposition → appearance → testing → tape and reel → packaging and shipping.

[0003] The lamination process is a critical step, designed to stack multiple layers of dielectric and protective films to form a block. Both the dielectric and protective films are protected by PET film (Polyethylene Elycol Terephthalate), which cannot remain within the block. Therefore, the quality of the block is directly related to the lamination method.

[0004] In the conventional process, the dielectric film needs to be flipped so that the PET film faces upwards. Then, the flipped dielectric film is transferred to the surface of the already stacked semi-finished product block and laminated. Due to inconsistent thermal shrinkage of the PET film, the PET film will deform along with the raw tape layer and the silver layer, resulting in different directions and degrees of deformation of the dielectric layers of different PET films. The alignment between the films will be greatly reduced. When they are misaligned, silver leakage is likely to occur at the cut points when cutting them into individual inductor units. Products with silver leakage are unusable defective products, which will affect the product qualification rate. Summary of the Invention

[0005] The technical problem this application aims to solve is: how to improve the pass rate of inductor blocks.

[0006] To address the aforementioned technical problems, this application provides an inductor stacking device and a stacking method.

[0007] Specifically, in a first aspect of this application, an inductor lamination apparatus is provided, wherein the materials include at least a PET film and a raw tape layer, and the lamination apparatus includes:

[0008] The system includes: a positioning lens for determining the position of the material on the moving worktable; a moving worktable on which the PET film side of the material is placed; a moving worktable for transporting the material from the working range of the positioning lens to the working range of the moving tool head; a moving tool head for gripping the material from the moving worktable; a cutting blade mounted on the moving tool head for cutting the raw material layer into the main body and the peeling part; the moving tool head also for transferring the cut material to the working range of the peeling tool head; a peeling tool head including a clamping mechanism and a moving mechanism; the clamping mechanism for simultaneously clamping the peeling part and the PET film; and a moving mechanism for moving the clamping mechanism up and down to separate the peeling part and the PET film from the main body; and a fixed worktable on which the moving tool head also transfers the material with the PET film peeled off onto the fixed worktable and stacks several pieces of material with the PET film peeled off.

[0009] In one embodiment, the laminating apparatus further includes a receiving trough located below the peeling tool head, the receiving trough being used to receive the peeled portion and PET film peeled off by the clamping mechanism.

[0010] In one embodiment, the stripping tool head further includes a rotating mechanism for adjusting the clamping angle of the clamping mechanism.

[0011] In one embodiment, the movable worktable further includes a first vacuum port, the movable work head includes a second vacuum port, and the fixed worktable includes a third vacuum port; the stacking device further includes a vacuum source, which is used to evacuate the first vacuum port, the second vacuum port, and the third vacuum port respectively.

[0012] In one embodiment, the vacuum source is a vacuum pump or a vacuum generator.

[0013] In one embodiment, the cutting blade is a cutting roller.

[0014] A second aspect of this application provides a method for stacking inductors. The stacking method is applied to a controller connected to the stacking equipment provided in the first aspect of this application. The stacking method includes: fixing material on a movable worktable; determining the position of the material on the movable worktable using a positioning lens; using the position as an offset parameter to control the movable worktable to transport the material from the working range of the positioning lens to the working range of a moving tool head; controlling the moving tool head to move towards the movable worktable, causing a cutting blade on the moving tool head to cut the raw material layer into a main body and a peeling part; controlling the moving tool head to transfer the cut material to the working range of a peeling tool head; controlling the clamping mechanism of the peeling tool head to simultaneously clamp the peeling part and the PET film; controlling the moving mechanism to drive the clamping mechanism downwards, separating the peeling part and the PET film from the main body; controlling the moving tool head to transfer the material with the PET film removed onto a fixed worktable; fixing the material with the PET film removed onto the fixed worktable; and controlling the moving tool head to move towards the fixed worktable to stack several pieces of material with the PET film removed.

[0015] In one embodiment, the lamination method further includes: controlling the moving tool head to maintain pressure on a predetermined time for a number of materials from which the PET film has been peeled off.

[0016] In one embodiment, the laminating apparatus further includes a receiving trough located below the peeling tool head, and the laminating method further includes: controlling the clamping mechanism of the peeling tool head to release the peeling part and the PET film, so that the peeling part and the PET film fall into the receiving trough.

[0017] In one embodiment, the movable worktable further includes a first vacuum port, the movable work head includes a second vacuum port, the fixed worktable includes a third vacuum port, and the lamination device further includes a vacuum source; the step of fixing the material on the movable worktable includes controlling the vacuum source to evacuate the first vacuum port, and using vacuum suction to fix the material on the movable worktable; the movable tool head evacuates the second vacuum port through the vacuum source to transport the material; the step of fixing the material with the PET film removed on the fixed worktable includes controlling the vacuum source to evacuate the third vacuum port, and using vacuum suction to fix the material with the PET film removed on the fixed worktable.

[0018] In one embodiment, the stacking apparatus and method for inductors according to this application have the following advantages compared with the prior art:

[0019] The lamination equipment in this embodiment places the PET film downwards, aligns it with a positioning camera, and then transports it to the peeling tool head. During transport, the position information obtained from the positioning camera can be used for correction. While the moving tool head picks up the material, it can cut the raw tape layer. Since PET cannot be cut, the peeling tool head simultaneously clamps a portion of the raw tape layer and the PET film, allowing the PET film to be peeled off. The material with the PET film removed is then transferred by the moving tool head to a fixed worktable for the lamination step. Because the PET film is no longer present during lamination, there is no risk of the PET film pulling and deforming the raw tape layer and silver layer together. This improves the material's alignment, significantly increases the yield of the inductor blocks, and consequently improves the overall yield of the inductor. Attached Figure Description

[0032] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but are not intended to limit the scope of this application.

[0033] In the description of this application, it should be understood that the terms "first," "second," etc., in the specification, claims, and accompanying drawings are intended to distinguish similar objects and are not used to describe a specific order or sequence. It should be understood that such terms are interchangeable where appropriate so that embodiments of this application can be implemented using notation methods other than those shown or described. Furthermore, "comprising," "having," and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that comprises a series of components, steps, or units is not necessarily limited to those components, steps, or units explicitly listed, but may also include other components, steps, or units not explicitly listed but inherent to these processes, methods, products, or devices.

[0034] It should be understood that, for ease of description, “material 2” in this application may refer to dielectric membrane 20 or protective membrane 21.

[0035] In various stacked electronic components, such as multilayer chip inductors, lamination is one of the important processes. The purpose of lamination is to stack multiple layers of material 2 together. Since material 2 itself has a certain degree of stickiness, a protective film is usually provided on one side of material 2 for easy storage and to facilitate the implementation of previous processes.

[0036] For example, in a multilayer inductor, such as Figure 1 As shown, a single dielectric film 20 is composed of a silver layer 203, a raw tape layer 202, and a PET film 201, and so on. Figure 2 As shown, a single protective film 21 is composed of a raw tape layer 202 and a PET film 201. It can be seen that a PET film 201 is present in any material 2. If the PET film 201 is involved in the lamination and then torn off, the silver layer 203 or the raw tape layer 202 will be pulled during the lamination, affecting the product quality. When it is torn off, it is difficult to tear or remove it completely due to the pressure it has been subjected to.

[0037] For example Figure 2As shown, this is the stacked electrode block, which is the internal electrode structure formed by the stacking and is the main part of the inductor. Exemplarily, the electrode block is formed by stacking an upper protective layer (i.e., three layers of protective film 21 with the PET film 201 removed), a lower protective layer, and an intermediate dielectric layer (i.e., three layers of dielectric film 20 with the PET film 201 removed). Understanding the structure of the electrode block provides a more intuitive understanding of why removing the PET film 201 is crucial in the lamination process.

[0038] Material 2 can be a dielectric film 20 or a protective film 21. Specifically, the dielectric film 20 can include a PET film 201, a raw tape layer 202 and a silver layer 203, and the protective film 21 can include a PET film 201 and a raw tape layer 202.

[0039] To overcome the shortcomings of the traditional method of laminating and then peeling the film, such as... Figure 3 As shown, a preferred embodiment of the present application is a stacking device 1.

[0040] The stacking equipment 1 is used to stack several materials 2 into a block. The stacking equipment 1 includes: a machine body 10, a positioning lens 11, a moving worktable 12, a moving tool head 13, a peeling tool head 14, and a fixed worktable 15.

[0041] All of the above-mentioned components can be connected to the body 10. In order to facilitate a direct understanding of the structure of the stacking device 1 in this application, the description of the body 10 in the text and drawings has been appropriately omitted. This omission is for the convenience of the reader and is not intended to limit the scope of protection of this application.

[0042] In the lamination equipment 1 of this application, specifically, the PET film 201 of material 2 is placed on the movable worktable 12 with one side facing down.

[0043] The movable worktable 12 is used to transport the material 2 from the working range of the alignment lens 11 to the working range of the movable tool head 13.

[0044] The moving tool head 13 is used to grab material 2 from the moving worktable 12.

[0045] The cutting blade 131 is mounted on the moving tool head 13. The cutting blade 131 is used to cut the raw strip layer 202 of the material 2 into the main body 2021 and the peeling part 2022. The moving tool head 13 is also used to transfer the cut material 2 to the working range of the peeling tool head 14.

[0046] The peeling tool head 14 includes a clamping mechanism 141 and a moving mechanism 142. The clamping mechanism 141 is used to clamp the peeling part 2022 and the PET film 201 at the same time, and the moving mechanism 142 is used to drive the clamping mechanism 141 to move up and down to separate the peeling part 2022 and the PET film 201 from the main body 2021.

[0047] The moving tool head 13 is also used to transfer the material 2 with the PET film 201 removed to the fixed worktable 15, and the moving tool head 13 is also used to stack several materials 2 with the PET film 201 removed.

[0048] Using the lamination equipment 1 of this application, during the production of inductors, after the material 2 with the PET film 201 is fed in, the PET film 201 can be kept facing downwards without needing to be flipped. Simultaneously, since the moving tool head 13 integrates a cutting blade 131, the material 2 can be cut simultaneously when the moving tool head 13 picks up the material 2. Figure 4 As shown, the lamination process is illustrated in detail. In the step of tearing the PET film 201, it can be seen that the raw material layer is cut off (if material 2 is a dielectric film 20, the silver layer 203 will also be cut off at the same time), while the PET layer retains its original structure due to its greater toughness.

[0049] The cut material 2 can be used as a reference. Figure 6 Partial view A shows the structure of the cut material 2 as an example. The dielectric film 20 is used as an example. If the cut material is a protective film 21, the silver layer 203 in the figure can be removed. After the raw material layer in the protective film 21 is cut, it can also be divided into a main body 2021 and a peeling part 2022.

[0050] Based on this, and in conjunction with the peeling tool head 14 in this application, after cutting, thanks to the certain thickness of the peeling part 2022, the clamping mechanism 141 in the peeling tool head 14 can simultaneously clamp the peeling part 2022 and the PET film 201. Then, the moving structure drives the entire peeling tool head 14 to move away from the moving tool head 13 (as exemplarily shown in the figure, it moves downwards), so that the peeling part 2022 and the PET film 201 can be peeled off together.

[0051] The material 2, after being peeled off from the PET film 201, is then transferred by the moving tool head 13 to the fixed workbench 15 for pressing. After pressing each piece, a block can be obtained.

[0052] Due to the special cutting method combined with the matching peeling tool head 14, the peeling of the PET film 201 before re-lamination is achieved. Based on this, the re-lamination results in a higher degree of alignment of the two layers of materials in the resulting block, thus producing a higher yield of inductors.

[0053] In one embodiment, the laminating device 1 further includes a receiving trough 16, which is located below the peeling tool head 14 and is used to receive the peeling portion 2022 and PET film 201 peeled off by the clamping mechanism 141.

[0054] In this application, the opening direction of the clamping mechanism 141 can always be horizontal. When the moving tool head 13 delivers the peeling part 2022 to the clamping mechanism 141, the clamping mechanism 141 clamps the peeling part 2022 and the PET film 201. With the cooperation of the moving mechanism 142, the peeling part 2022 and the PET film 201 can be peeled off.

[0055] Since material 2 usually has a certain length, when the opening direction is always facing one direction, different sections are prone to different stresses. Therefore, uneven stress is likely to occur when tearing the film, resulting in reduced flatness of the raw material layer.

[0056] Therefore, in one embodiment of this application, as Figure 1 and Figure 8 As shown, the peeling tool head 14 may also include a rotating mechanism 143, which is used to adjust the clamping angle of the clamping mechanism 141.

[0057] Due to the presence of the rotating mechanism 143, the opening direction of the clamping mechanism 141 can be adjusted at any time. For example, the opening direction of the clamping mechanism 141 can always point towards the tearing point. Since the tearing point is constantly changing during tearing, the rotating mechanism 143 drives the clamping mechanism 141 to rotate accordingly, which can appropriately improve the uniformity of force and thus improve the flatness of the raw material layer.

[0058] In this application, the material 2 is fixed and transferred in multiple places, and various methods can be used for fixing and transferring. For example, in one embodiment, a clamp can be used to hold the material 2 on a moving worktable 12, a moving tool head 13, and a fixed worktable 15.

[0059] In another embodiment, such as Figure 3 As shown, the movable worktable 12 may include a first vacuum port, the movable workhead may include a second vacuum port, and the fixed worktable 15 may include a third vacuum port.

[0060] Based on this, the stacking device 1 may also include a vacuum source, which is used to evacuate the first vacuum hole, the second vacuum hole and the third vacuum hole respectively.

[0061] By employing the aforementioned vacuuming method, and considering the flatness of the PET film 201 itself, the vacuum holes, combined with a vacuum source, can utilize the suction force of the vacuum to fix the material 2 onto components such as the movable worktable 12, the movable tool head 13, and the fixed worktable 15. By switching the first, second, and third vacuum holes on or off, the material 2 can be fixed or transferred.

[0062] Based on the above embodiments, in one embodiment, the vacuum source can be a vacuum pump or a vacuum generator.

[0063] A vacuum can be directly generated using a vacuum pump. However, by using a vacuum generator, the compressed air output can be converted into a vacuum for intake, allowing compressed air to be reused to create new functions based on existing pneumatic components, thereby saving production costs.

[0064] If a vacuum pump is selected as the vacuum source, any of the following can be used: piston vacuum pump, rotary vane vacuum pump, or molecular vacuum pump.

[0065] In this application, the cutting blade 131 can take many forms. For example, in one embodiment, a strip blade can be used to cut the material 2 in one go.

[0066] In another embodiment, the cutting blade 131 can be a cutting roller. When the roller cuts at high speed, it can effectively reduce heat accumulation during the cutting process, preventing the material from deforming, melting, or scorching due to overheating. This is particularly suitable for the temperature-sensitive PET film 201 in this application. Because the PET film 201 is not easily affected by heat and is therefore less prone to deformation, the flatness of the raw material layer can be better maintained during the cutting stage.

[0067] In this application, as Figure 5 As shown, since material 2 is placed with the PET film 201 facing down, there is no need to flip it during subsequent steps. This eliminates the need for flipping and the corresponding mechanism, saving production time. Each layer can save a certain amount of time, and over time, it can almost double the production efficiency.

[0068] In traditional solutions, such as Figure 7 As shown, since there is no peeling tool head 14 similar to that in this application, it is necessary to rely on the adhesive force of the pads to fix the top layer of material 2 after lamination, and then perform a manual film peeling operation. Because the PET layer needs to be in direct contact with the worktable and aligned, it is also impossible to turn the PET film 201 upward during feeding. Therefore, the flipping mechanism in the traditional solution is difficult to eliminate, and the resulting processing time deficiency cannot be compensated.

[0069] In this application, the moving tool head 13 can transfer the material 2 after the film is torn to the fixed worktable 15. At the same time, the moving tool head 13 performs a pressure holding operation on the material 2 on the fixed worktable 15. After the pressure holding is completed, a new material 2 is transferred, and the process is repeated to form a block.

[0070] In another embodiment of this application, such as Figure 9 As shown, an additional pressure-holding tool head can be provided, which is correspondingly set with the fixed worktable 15. The pressure-holding tool head can move up and down. When the pressure-holding tool head and the fixed worktable 15 perform a pressure-holding operation on the previous material 2, the moving work head can cooperate with the peeling tool head 14 to peel off the film on the next material 2. Therefore, pressure holding does not need to wait for film peeling to be completed, and film peeling does not need to wait for pressure holding to be completed, thus saving at least one step of operation time, thereby greatly improving the production efficiency of the product.

[0071] To avoid interference, the upward stroke of the pressure holding tool head needs to exceed that of the moving tool head 13.

[0072] Corresponding to the inductor stacking device 1, this application also provides an inductor stacking method, which is applied to a controller connected to the stacking device 1 provided in the first aspect of this application. The controller can be a controller installed in the stacking device 1 or a controller external to the stacking device 1; this application does not impose any limitations on this.

[0073] Specifically, such as Figure 10 As shown, the stacking method can include:

[0074] S101. Fix material 2 on the movable worktable 12.

[0075] S102. The position of material 2 on the moving worktable 12 is determined by the alignment lens 11.

[0076] S103. Using the position as an offset parameter, control the moving worktable 12 to transport the material 2 from the working range of the alignment lens 11 to the working range of the moving tool head 13.

[0077] S104. Control the moving tool head 13 to move toward the moving worktable 12, so that the cutting blade 131 on the moving tool head 13 cuts the raw strip layer 202 of the material 2 into the main body 2021 and the peeling part 2022.

[0078] S105. Control the moving working head to transfer the cut material 2 to the working range of the peeling tool head 14.

[0079] S106, The clamping mechanism 141 of the control peeling tool head 14 simultaneously clamps the peeling part 2022 and the PET film 201.

[0080] S107, the control moving mechanism 142 drives the clamping mechanism 141 to move downward, so that the peeling part 2022 and the PET film 201 are separated from the main body part 2021.

[0081] S108, control the moving tool head 13 to transfer the material 2 with the PET film 201 removed to the fixed worktable 15.

[0082] S109. Fix the material 2 with the PET film 201 removed onto the fixed workbench 15.

[0083] S110, control the moving tool head 13 to move toward the fixed worktable 15, and stack several materials 2 with the PET film 201 peeled off into a block.

[0084] In one embodiment, the lamination method may further include: controlling the moving tool head 13 to hold pressure on a plurality of materials 2 after the PET film 201 has been peeled off for a preset time.

[0085] In another embodiment, the laminating device 1 further includes a receiving trough 16, which is located below the peeling tool head 14. The laminating method further includes controlling the clamping mechanism 141 of the peeling tool head 14 to release the peeling part 2022 and the PET film 201, so that the peeling part 2022 and the PET film 201 fall into the receiving trough 16.

[0086] In another embodiment, the movable worktable 12 further includes a first vacuum port, the movable work head includes a second vacuum port, the fixed worktable 15 includes a third vacuum port, and the stacking device 1 further includes a vacuum source.

[0087] The step of fixing material 2 on the movable worktable 12 includes controlling the vacuum source to evacuate the first vacuum hole and using the vacuum suction to fix material 2 on the movable worktable 12.

[0088] The moving tool head 13 evacuates the second vacuum hole through a vacuum source to transport material 2.

[0089] The step of fixing the material 2 with the PET film 201 removed onto the fixed worktable 15 includes controlling the vacuum source to evacuate the third vacuum hole and using the vacuum suction to fix the material 2 with the PET film 201 removed onto the fixed worktable 15.

[0090] In summary, this application provides an inductor lamination device 1 and a lamination method. The PET film 201 is placed downwards, aligned by a positioning camera, and then transported to a peeling tool head 14. During transport, the device can be corrected based on the positional information obtained from the positioning camera. While the moving tool head 13 picks up the material 2, it can cut the raw tape layer 202. Since PET cannot be cut, the peeling tool head 14 simultaneously clamps a portion of the raw tape layer 202 and the PET film 201, allowing the PET film 201 to be peeled off. The material 2 with the PET film 201 removed is then transferred by the moving tool head 13 to a fixed worktable 15 for lamination. Because the PET film 201 is no longer present during lamination, the PET film 201 does not cause deformation of the raw tape layer 202 and the silver layer 203, thus improving the alignment of the material 2 and significantly increasing the yield of the inductor, thereby improving the overall yield of the inductor.

[0091] The above are merely preferred embodiments of this application. It should be noted that those skilled in the art can make several improvements and substitutions without departing from the technical principles of this application, and these improvements and substitutions should also be considered within the scope of protection of this application.
