Description

Technical Field

[0001] The present application relates to a device for manufacturing an inductor, and in particular to a stacking device and a stacking method for an inductor. Background Art

[0002] At present, the multilayer chip inductor is a widely used miniature electronic component with a complicated manufacturing process, which mainly includes the following steps: sanding → casting → film cutting → punching → printing → stacking → lamination → cutting → degumming → firing → chamfering → end sealing → end burning → deposition → appearance → testing → taping → packaging and delivery.

[0003] The lamination process is a key process, which aims to stack the multi-layer dielectric film and protective film to form a bar. The materials of the dielectric film and protective film are protected by PET film (Polyethylene Elycol Terephthalate), and the PET film cannot be retained in the bar. The quality of the bar is closely related to the lamination method.

[0004] In the conventional scheme, the dielectric film needs to be flipped over, with the PET film facing upward, and then the flipped dielectric film is transferred to the surface of the stacked semi-finished product block and laminated. When the PET film shrinks inconsistently, the PET film will pull the raw tape layer and the silver layer to deform together, causing the dielectric layers of different PET films to deform in different directions and to different degrees. The stacking degree between the films will be greatly reduced. When they are not aligned, when they are cut into single units of the inductor, the single units at the cutting point are prone to silver leakage. Products with silver leakage are defective products that cannot be used, thus affecting the product qualification rate. Summary of the invention

[0014] According to a second aspect of the present application, there is provided a method for stacking an inductor. The stacking method is applied to a controller connected to the stacking device provided by the first aspect of the present application, and the stacking method comprises: fixing a material on a movable workbench; determining the position of the material on the movable workbench by means of an alignment lens; using the position as an offset parameter, controlling the movable workbench to transport the material from the working range of the alignment lens to the working range of a movable tool head; controlling the movable tool head to move toward the movable workbench so that a cutting knife on the movable tool head cuts a raw tape layer of the material into a main body and a stripping portion; controlling the movable work head to transfer the cut material to the working range of the stripping tool head; controlling a clamping mechanism of the stripping tool head to clamp the stripping portion and the PET film at the same time; controlling the movable mechanism to drive the clamping mechanism to move downward so that the stripping portion and the PET film are separated from the main body; controlling the movable tool head to move the material stripped of the PET film onto the fixed workbench; fixing the material stripped of the PET film on the fixed workbench; and controlling the movable tool head to move toward the fixed workbench to stack a number of materials stripped of the PET film.

[0015] In one embodiment, the lamination method further comprises: controlling the moving tool head to maintain pressure on the plurality of materials peeled off the PET film for a preset time.

During the transportation process, correction can be performed according to the position information obtained by the alignment camera. While the mobile tool head is picking up, the raw tape layer in the material can be cut. Since PET cannot be cut, the stripping tool head simultaneously clamps a part of the raw tape layer and the PET film, and the PET film can be torn off. The material with the PET film torn off is then transferred to a fixed workbench by the mobile tool head for the lamination step. Since the PET film no longer exists during lamination, the PET film will not pull the raw tape layer and the silver layer together to deform, thereby improving the stacking degree of the material, which can significantly improve the qualified rate of the bar block, and then improve the qualified rate of the entire inductor.

[0032] The specific implementation methods of the present application are further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application but are not intended to limit the scope of the present application.

[0033] In the description of the present application, it should be understood that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned 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 the embodiments of the present application can be implemented in a marking manner other than illustrated or described. In addition, "including", "having" and any variation thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of components, steps or units is not necessarily limited to those components, steps or units explicitly listed, and may also include other components, steps or units that are not explicitly listed but are inherent to these processes, methods, products or devices.

[0034] It should be understood that, for the convenience of description, the “material 2 ” in the present application may refer to the dielectric diaphragm 20 or the protective diaphragm 21 .

[0035] In various laminated electronic components, such as laminated chip inductors, lamination is one of the important processes. The purpose of lamination is to stack multiple layers of materials 2 together. Since the materials 2 themselves have a certain viscosity, a protective film is usually provided on one side of the materials 2 for the convenience of storage and implementation of the pre-process.

[0036] For example, in a stacked inductor, Figure 1 As shown, a single dielectric film 20 is composed of a silver layer 203, a green tape layer 202 and a PET film 201. Figure 2 As shown, a single protective film sheet 21 is composed of a raw tape layer 202 and a PET film 201. It can be seen that the PET film 201 exists in any material 2, and if the PET film 201 is involved in lamination and then torn off, the silver layer 203 or the raw tape layer 202 will be pulled during lamination, affecting the product quality, and it is difficult to tear or tear off completely due to excessive pressure when torn off.

[0037] For example Figure 2The block is shown as a stacked block, which is also the internal electrode structure formed by stacking, and is the main part of the inductor. As an example in the figure, the block is obtained by stacking the upper protective layer (that is, the protective film sheet 21 with three layers of PET film 201 torn off), the lower protective layer, and the middle dielectric layer (that is, the dielectric film sheet 20 with three layers of PET film 201 torn off). Combined with the structure of the block, it can be more intuitively understood why tearing off the PET film 201 is the most important part of the lamination process.

[0038] The material 2 may be a dielectric film 20 or a protective film 21 . Specifically, the dielectric film 20 may include a PET film 201 , a green tape layer 202 and a silver layer 203 , and the protective film 21 may include a PET film 201 and a green tape layer 202 .

[0039] In order to overcome the defects of the traditional solution of laminating first and then tearing the film, Figure 3 As shown, a stacking device 1 according to a preferred embodiment of the present application is shown.

[0040] The stacking device 1 is used to stack a plurality of materials 2 into blocks. The stacking device 1 comprises: a body 10 , an alignment lens 11 , a movable workbench 12 , a movable tool head 13 , a stripping tool head 14 , and a fixed workbench 15 .

[0041] The above-mentioned several components can all be connected to the body 10. In order to facilitate an intuitive understanding of the structure of the stacking device 1 in the present application, the present application appropriately omits the description of the body 10 in the text records and drawings. This omission is for the convenience of readers to understand and is not used to limit the scope of protection of the present application.

[0042] In the laminating device 1 of the present application, specifically, the PET film 201 of the material 2 is placed on the movable workbench 12 with one side facing downward.

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

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

[0045] The cutting knife 131 is arranged on the movable tool head 13 , and is used to cut the raw tape layer 202 of the material 2 into a main body portion 2021 and a stripping portion 2022 . The movable tool head 13 is also used to transfer the cut material 2 to the working range of the stripping tool head 14 .

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

[0047] The mobile tool head 13 is further used to move the material 2 with the PET film 201 peeled off onto the fixed workbench 15 , and the mobile tool head 13 is further used to stack several materials 2 with the PET film 201 peeled off.

[0048] When the laminating device 1 of the present application is used to produce inductors, after the material is fed in, the material 2 with the PET film 201 can always keep the PET film 201 facing downward without turning it over. At the same time, since the cutting knife 131 is integrated on the moving tool head 13, the material 2 can be cut at the same time when the moving tool head 13 takes the material 2. Figure 4 As shown, the lamination process is shown in detail. Combined with the step of tearing the PET film 201, it can be seen that the raw material layer is cut (if the material 2 is a dielectric film 20, the silver layer 203 will also be cut at the same time), while the PET layer maintains its original structure due to its greater toughness.

[0049] The cut material 2 can be referenced Figure 6 The structure of the cut material 2 is exemplarily shown in the partial view A. The dielectric film 20 is taken as an example in the figure. If the cut material is the protective film 21, the silver layer 203 in the figure can be removed. The raw material layer in the protective film 21 can also be divided into a main body 2021 and a peeling portion 2022 after being cut.

[0050] Based on this, in combination with the peeling tool head 14 in the present application, after cutting, thanks to the certain thickness of the peeling portion 2022, the clamping mechanism 141 in the peeling tool head 14 can clamp the peeling portion 2022 and the PET film 201 at the same time, and then the moving structure drives the entire peeling tool head 14 to move in a direction away from the moving tool head 13 (as exemplified in the figure, downward movement), and the peeling portion 2022 can be torn off together with the PET film 201.

[0051] The material 2 with the PET film 201 torn off is then transferred by the mobile tool head 13 to the fixed workbench 15 for pressing. After the materials are fed and pressed one by one, a bar block can be obtained.

[0052] Due to the special cutting method combined with the matching stripping tool head 14, the work of stripping the PET film 201 before re-lamination is achieved. Based on this re-lamination, the alignment of several material 2 layers in the obtained block is higher, so the yield of the produced inductor is also higher.

[0053] In one embodiment, the laminating device 1 further includes a material receiving trough 16 , which is disposed below the stripping tool head 14 , and is used to accommodate the stripping portion 2022 and the PET film 201 stripped by the clamping mechanism 141 .

[0054] In the present application, the opening direction of the clamping mechanism 141 can always be along the horizontal direction. When the moving tool head 13 sends the peeling part 2022 to the clamping mechanism 141, the clamping mechanism 141 clamps the peeling part 2022 and the PET film 201, and cooperates with the moving mechanism 142 to tear off the peeling part 2022 and the PET film 201.

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

[0056] Therefore, in one embodiment of the present application, if Figure 1 and Figure 8 As shown, the stripping tool head 14 may further include a rotating mechanism 143 , and the rotating mechanism 143 is used to adjust the clamping angle of the clamping mechanism 141 .

[0057] Due to the existence 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 to the tearing position. Since the tearing position keeps changing during tearing, the rotating mechanism 143 drives the clamping mechanism 141 to rotate accordingly, which can appropriately improve the uniformity of the force, thereby improving the flatness of the raw material layer.

[0058] In the present application, the material 2 is fixed and transferred at multiple locations, and various methods can be used for the fixation and transfer. For example, in one embodiment, a clamp can be used to clamp the material 2 on the mobile workbench 12, the mobile tool head 13, and the fixed workbench 15.

[0059] In another embodiment, Figure 3 As shown, the movable workbench 12 may include a first vacuum hole, the movable work head may include a second vacuum hole, and the fixed workbench 15 may include a third vacuum hole.

[0060] Based on this, the lamination device 1 may further 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 the above-mentioned vacuuming method, combined with the flatness of the PET film 201 itself, the vacuum hole combined with the vacuum source can use the vacuum attraction to fix the material 2 on the mobile workbench 12, the mobile tool head 13 and the fixed workbench 15. By switching the first vacuum hole, the second vacuum hole and the third vacuum hole on or off, the material 2 can be fixed or transferred.

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

[0063] A vacuum pump can directly generate a vacuum. A vacuum generator can convert the discharged compressed air into a vacuum for intake. Based on the existing pneumatic components, compressed air can be reused to generate new functions, which can save production costs.

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

[0065] In the present application, the cutting knife 131 can be in various forms. For example, in one embodiment, a strip-shaped knife can be used to cut the material 2 at one time.

[0066] In another embodiment, the cutting blade 131 may be a cutting roller. When the roller cuts at high speed, it can effectively reduce the heat accumulation during the cutting process, and prevent the material from being deformed, melted, or burned due to overheating, which is just suitable for the temperature-sensitive PET film 201 in this application. Since the PET film 201 is not easily affected by heat and is difficult to deform, the flatness of the raw material layer can be better maintained during the cutting stage.

[0067] In this application, if Figure 5 As shown, since the material 2 is placed with the PET film 201 facing downward, it does not need to be flipped during the subsequent steps. Therefore, the flipping step and the corresponding mechanism are omitted, which can save production time. Each layer can save a certain amount of time, and the production efficiency can be increased nearly exponentially in the long run.

[0068] In traditional schemes, Figure 7 As shown, since there is no similar peeling tool head 14 in the present application, the topmost material 2 has to be fixed by the adhesive force of the block after lamination, and then the film tearing operation is performed manually. Since the PET layer needs to directly contact the workbench and needs to be aligned, the PET film 201 cannot be turned upward when feeding, so the flipping mechanism in the traditional solution is difficult to cancel, and the defect of processing time caused by this cannot be compensated.

[0069] In the present application, the material 2 after film tearing can be transferred to the fixed workbench 15 by the mobile tool head 13, and at the same time, the mobile tool head 13 performs a pressure holding operation on the material 2 on the fixed workbench 15. After the pressure holding operation is completed, new material 2 is transferred, and this cycle is repeated to form a block.

[0070] In another embodiment of the present application, Fig. 9 As shown, an additional pressure-maintaining tool head can be provided, which is provided corresponding to the fixed workbench 15 and can move up and down. When the pressure-maintaining tool head and the fixed workbench 15 perform pressure-maintaining operation on the previous material 2, the movable work head can cooperate with the stripping tool head 14 to tear the film of the next material 2. Therefore, pressure maintenance does not need to wait for the film tearing to be completed, and film tearing does not need to wait for the pressure maintenance to be completed, so at least one step of operation time is saved, thereby greatly improving the production efficiency of the product.

[0071] In order to avoid interference, the upward stroke of the pressure-maintaining tool head needs to exceed that of the moving tool head 13 .

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

[0073] Specifically, Fig.10 As shown, the stacking method may include:

[0074] S101 , fixing the material 2 on the mobile workbench 12 .

[0075] S102 , determining the position of the material 2 on the movable workbench 12 through the alignment lens 11 .

[0076] S103 , using the position as an offset parameter, controlling the mobile workbench 12 to transport the material 2 from the working range of the alignment lens 11 to the working range of the mobile tool head 13 .

[0077] S104 , controlling the movable tool head 13 to move toward the movable workbench 12 , so that the cutting knife 131 on the movable tool head 13 cuts the raw tape layer 202 of the material 2 into a main body portion 2021 and a peeling portion 2022 .

[0078] S105 , controlling the mobile working head to transfer the cut material 2 into the working range of the stripping tool head 14 .

[0079] S106 , controlling the clamping mechanism 141 of the stripping tool head 14 to clamp the stripping portion 2022 and the PET film 201 simultaneously.

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

[0081] S108 , controlling the mobile tool head 13 to move the material 2 with the PET film 201 peeled off onto the fixed workbench 15 .

[0082] S109 , fixing the material 2 with the PET film 201 peeled off on the fixed workbench 15 .

[0083] S110, controlling the mobile tool head 13 to move toward the fixed workbench 15, and stacking the plurality of materials 2 from which the PET films 201 have been peeled off into blocks.

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

[0085] In another embodiment, the stacking device 1 also includes a material receiving trough 16, which is arranged below the stripping tool head 14, and the stacking method also includes: controlling the clamping mechanism 141 of the stripping tool head 14 to loosen the stripping part 2022 and the PET film 201, so that the stripping part 2022 and the PET film 201 fall into the material receiving trough 16.

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

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

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

[0089] The step of fixing the material 2 with the PET film 201 peeled off on the fixed workbench 15 includes controlling the vacuum source to evacuate the third vacuum hole, and fixing the material 2 with the PET film 201 peeled off on the fixed workbench 15 by using vacuum suction.

[0090] In summary, the embodiment of the present application provides a lamination device 1 and a lamination method for an inductor, which is placed with the PET film 201 facing downward, and transported to the stripping tool head 14 after alignment by the alignment camera. During the transportation process, correction can be performed according to the position information obtained by the alignment camera. While the mobile tool head 13 is taking, the raw tape layer 202 in the material 2 can be cut. Since the PET cannot be cut, the stripping tool head 14 simultaneously clamps a part of the raw tape layer 202 and the PET film 201, and the PET film 201 can be torn off. The material 2 with the PET film 201 torn off is then transferred to the fixed workbench 15 by the mobile tool head 13 for the lamination step. Since the PET film 201 does not exist during lamination, the PET film 201 will not pull the raw tape layer 202 and the silver layer 203 together to deform, thereby improving the stacking degree of the material 2, which can significantly improve the qualified rate of the bar block, and then improve the qualified rate of the entire inductor.

[0091] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present application. These improvements and substitutions should also be regarded as the scope of protection of the present application.
