Description

Technical Field

[0001] The invention relates to a roller head cutting blade structure and an MLCC lamination device. Background Art

[0002] The existing MLCC stacking method is as follows: first, the dielectric layer film and the ceramic layer film are placed on both sides of the stacking table respectively, and then stacked together on the stacking table in the order of multiple ceramic layers, multiple dielectric layers, and multiple ceramic layers according to the work order; second, when the ceramic layer film is adsorbed on the ceramic layer cutting table, the stacking cutting head moves above the ceramic layer cutting table and then descends to the surface of the ceramic layer; after the circular cutting knife cuts the ceramic layer, it is adsorbed by the vacuum holes on the bottom of the stacking cutting head so that the cut ceramic layer is adsorbed on the bottom surface of the stacking cutting head; finally, after the stacking cutting head returns to the top of the stacking table and descends to the surface of the stacking table (applying a certain amount of pressure to the stacking table), when the stacking cutting head rises again, the vacuum holes blow air to make the ceramic layer adhere to the surface of the stacking table. When stacking the dielectric layer, the same cutting process as above is followed, and finally, multiple ceramic layers, multiple dielectric layers, and multiple ceramic layers can be stacked together in order according to the above method.

[0003] The above-mentioned stacking method has the following disadvantages: the stacking cutting head needs to move left and right, and up and down; and during cutting, the cutting circular knife needs to cut before it can adsorb the ceramic layer and move, and when placing the dielectric layer or ceramic layer from the stacking cutting head to the stacking table, it needs to be pre-pressed. The above-mentioned process will result in a waste of time and low cutting efficiency; in addition, because the contact surface between the stacking table and the stacking cutting head is a rectangular surface, that is, after each stacking, bubbles are often generated after the stacking due to the inability to discharge the gas, thereby affecting the stacking quality and product performance.

DETAILED DESCRIPTION

[0034] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0035] like Figure 1-2 The figure schematically illustrates a roller head cutting blade structure according to an embodiment of the present invention, used for cutting a film roll having both a ceramic layer and a dielectric layer. The structure comprises a crosscutting blade 13 rotating shaft and a cutting roller rotatably mounted on the crosscutting blade 13 shaft. The radial surface of the cutting roller comprises a first roller surface 11 and a second roller surface 12 having an axial diameter greater than the axial diameter of the first roller surface 11. The second roller surface 12 is arc-shaped, with crosscutting blades 13 extending axially disposed on both sides of the second roller surface 12. The arc length of the second roller surface 12 is greater than or equal to the length of the dielectric layer and the ceramic layer on the film roll. Multiple suction holes 14 are also evenly distributed on the second roller surface 12, each connected to an air source. When the cutting roller rotates, the two crosscutting blades 13 sequentially cut the film roll. Because the arc length of the second roller surface 12 is greater than or equal to the length of the dielectric layer and the ceramic layer on the film roll, the length of the film roll cut is the same as the length of the dielectric layer and the ceramic layer. After cutting, the film roll can be directly attached to the cutting roller using the suction holes 14, resulting in high cutting efficiency.

[0036] The principle of the cross-cutting knife 13 cutting the dielectric layer or ceramic layer is as follows: a rubber wheel is set on the upper part of the cutting roller, and the rubber wheel presses the dielectric layer film onto the cross-cutting knife 13 with a certain pressure to complete the cutting of the dielectric layer or ceramic layer. In order to reduce the impact of the blade compartment on the film, the distance between the two cross-cutting knives 13 should be as small as possible. At the same time, the edges of the compartments need to be rounded.

[0037] In order to provide uniform adsorption force, there are multiple adsorption holes 14 that are evenly arranged in multiple rows. Each row of adsorption holes 14 is connected to a connecting hole, and each connecting hole is connected to the air source.

[0038] In order to ensure that only the dielectric layer or the ceramic layer is cut and the film cannot be cut during cutting, the edges of both sides of the second roller surface 12 are provided with inwardly concave T-slots 15, one end of the cross-cutting knife 13 is stuck in the T-slot 15, and the other end of the T-slot 15 extends to the outside of the T-slot 15, and the other end of the T-slot 15 has a cutting edge; a first elastic member 16 is provided in the T-slot 15, one end of the first elastic member 16 abuts against the cross-cutting knife 13, and the other end of the first elastic member 16 abuts against the bottom of the T-slot 15; the elastic force of the first elastic member 16 is greater than the force of the cross-cutting knife 13 when cutting the dielectric layer and the ceramic layer at the same time, and is less than the force of cutting the dielectric layer, the ceramic layer and the film at the same time. During cutting, the cross-cutting knife can cut the dielectric layer or the ceramic layer, but cannot cut the film.

[0039] Furthermore, one end of the cross-cutting knife 13 has a base plate 17, on which a blade is vertically fixedly connected, and the blade has a cutting edge; the base plate 17 is locked in the T-slot 15, and the base plate 17 abuts against the first elastic member 16; the first elastic member 16 is specifically a spring.

[0040] like Figure 1-5 As shown, the MLCC stacking device of the embodiment of the present invention is schematically shown, which is used for cutting a film roll with a ceramic layer and a dielectric layer arranged at the same time, including a support 5, on which are arranged, from left to right, a reeling roller 2, a vertical cutting knife structure 3 for cutting the width of the film roll, a cross-cutting knife 13 structure for cutting the film roll and a reeling roller 4. Two cross-cutting knife structures 13 are arranged in sequence along the moving direction of the film roll, and each cross-cutting knife 13 structure includes a flexible wheel 10 and a roller head cutting knife structure that are abutted and fitted up and down; the flexible wheel 10 is specifically a rubber wheel rotatably arranged on the support 5; the film roll is taken off the reeling roller The film roll is wound after being cut in width by the vertical cutting knife structure 3 and in length by the cross cutting knife structure 13; the roller head cutting knife structure is the structure shown in the embodiment of the roller head cutting knife structure described above; a supporting platform 6 is provided on the support 5 at the lower part of the roller head cutting knife structure, and the adsorption hole 14 of the roller head cutting knife structure can adsorb the cut film roll on the second roller surface 12, and the cutting roller can be rotated to the lower part to fit with the supporting platform 6, so that the cut film roll can be placed on the supporting platform 6 when the cutting roller is released from adsorption and blown. The supporting platform 6 is used to carry the cut film roll for lamination.

[0041] The vertical cutter structure 3 includes a vertical cutter roller 31 and a vertical cutter support block 32 fixed to a support 5. A circular cutter shaft 33 extending in a forward and backward direction is fixed to the vertical cutter support block 32. Two circular cutter support arms 34 are rotatably mounted on the circular cutter shaft 33. Each circular cutter support arm 34 has a circular cutter 35 at its end for cutting the width of the film roll. The two circular cutter support arms 34 are spaced apart, with the spacing between the two circular cutters 35 being the width of the film roll to be cut. A second elastic member is disposed between each circular cutter support arm 34 and the vertical cutter support block 32. The elastic force of the second elastic member is greater than the force exerted by the circular cutter 35 when simultaneously cutting the dielectric layer and the ceramic layer, but less than the force exerted by the circular cutter 35 when simultaneously cutting the dielectric layer, the ceramic layer, and the film. The circular cutter shaft 33 rotates, driving the circular cutter support arms 34 to rotate. Under the action of the second elastic member, the circular cutter contact and cut the film roll. The elastic force of the second elastic member is set so that only the ceramic layer and the dielectric layer are cut without cutting the film layer.

[0042] Among them, a tension shaft 7 is provided between the unwinding roller 2 and the vertical cutting knife structure 3, between the vertical cutting knife structure 3 and the cross-cutting knife 13 structure, and between the cross-cutting knife 13 structure and the winding roller 4. The tension shaft 7 can move up and down, and guide rollers are provided between the unwinding roller and the vertical cutting knife structure 3, and between the tension shaft 7 and the cross-cutting knife 13 structure.

[0043] The present application includes three tension shafts 7, which are arranged in series with the rubber wheels. The three tension shafts 7 are at the same horizontal position, and the line connecting the top three points of the three tension shafts 7 should be higher than the point where the rubber wheel contacts the second roller surface 12. When the second roller surface 12 contacts the rubber wheel, pressure is applied, causing the film to deform and buckle under the rubber wheel. To maintain consistent tension, the three tension shafts 7 must be lowered. Simultaneously, when the rubber wheel is no longer in contact with the second roller surface 12, the three tension shafts 7 must be raised. The film tension balance is maintained by the up and down movement of the tension shafts 7.

[0044] Furthermore, a bearing seat 8 and a slider 9 are fixedly provided at the lower part of the support 5. A sliding groove 81 is provided in the bearing seat 8 along the moving direction of the film roll. The slider 9 is slidably set on the groove edge of the sliding groove 81. The lower part of the slider 9 extends downward and is matched and installed on the screw 82. The screw 82 is connected to the left and right drive motors; the left and right drive motors can drive the screw 82 to rotate to move the slider 9 left and right.

[0045] Furthermore, two supporting platforms 6 are provided, one located below each of the two roller head cutting blade structures. Two vertically extending screws 91 are rotatably mounted on the slider 9, with the two supporting platforms 6 threadedly mounted on the top of each screw 91. Each screw 91 is connected to a vertical drive motor at its bottom. The vertical drive motors rotate, driving the screws 91 to rotate, thereby driving the two supporting platforms 6 threadedly mounted on the screws 91 up and down, ensuring consistent pressure between the supporting platforms and the second roller surface 12 at all times. After the cross-cutting blade 13 cuts the film roll to form the dielectric layer and the ceramic layer, the vertical drive motors drive the supporting platforms 6 up and down, placing the dielectric layer and the ceramic layer on top of the supporting platforms 6.

[0046] Furthermore, each supporting platform 6 is provided with a plurality of air holes 61 .

[0047] The slider 9 is provided with a guide protrusion extending up and down, and the edge of each supporting platform 6 is provided with a groove matching the guide protrusion to facilitate the upward and downward guided movement of the supporting platform 6.

[0048] The working principle of the MLCC stacking device of the present invention is as follows: the ceramic layer and the dielectric layer are placed on the same film roll, and the order of silk screen printing is controlled by a silk screen printer to control the ratio of the number of ceramic layers to the dielectric layer. Assuming that the work order requires a bar block with the number of bottom ceramic layers, dielectric layers, and surface ceramic layers as 1, 2, and 1, then since the cross-cutting knife 13 structure of the present application has two, that is, each time is equivalent to stacking two bars, then the dielectric layers and ceramic layers on the film roll are distributed as follows: 2 ceramic layers, 4 dielectric layers, and 2 ceramic layers. Then, the subsequent dielectric layers and ceramic layers of the film roll are continuous in this order. To achieve this step, when silk screen printing, the dielectric layer is printed according to the intervals between the ceramic layers.

[0049] Specifically, the film roll is fixed on the unwinding wheel, and the film transfer position between the shafts is as follows: Figure 3 As shown, the film is driven from the unwinding wheel to the winding wheel, first reaching the vertical cutter structure 3, where the circular blade 35 on the vertical cutter completes the left and right cuts of the dielectric or ceramic layer on the film. Then, when it reaches the second roller surface 12, the crosscutting blade 13 on one side of the second roller surface 12 completes the first cut of the dielectric or ceramic layer. Then, through the air holes on the second roller surface 12, air is sequentially sucked out, peeling the dielectric or ceramic layer off the film onto the second roller surface 12. The crosscutting blade 13 on the other side of the second roller surface 12 completes the second cut of the dielectric or ceramic layer. At this point, the entire dielectric or ceramic layer is completely peeled off onto the second roller surface 12.

[0050] When the second roller surface 12 reaches the left side of the carrier, the air holes on the second roller surface 12 release air in sequence to place the dielectric layer or ceramic layer on the left side of the carrier. At this time, since the first roller surface 11 does not contact the film, the dielectric layer or ceramic layer below the peeled dielectric layer or ceramic layer will not be peeled off. At this time, this dielectric layer or ceramic layer will contact the cross-cutting knife 13 on the left side of the second roller surface 12 of the cross-cutting knife 13 structure on the right side under the action of the rightward movement of the carrier 6, completing the first cutting. Then the cross-cutting knife 13 structure on the right side cuts the roll film at the same time, which is consistent with the above-mentioned cross-cutting knife 13 structure process on the left side. The obtained dielectric layer or ceramic layer can be directly stacked on the dielectric layer or ceramic layer cut by the cross-cutting knife 13 structure on the left side. When the cross-cutting knife 13 structure has stacked the dielectric layer or ceramic layer, that is, when the first roller surfaces 11 of the two cross-cutting knife 13 structures are facing the carrier, the carrier moves to the left. When the two cross-cutting knife 13 structures are about to contact the carrier next time, they move to the right together, repeating the cycle to complete the stacking.

[0051] Assuming that the length of a dielectric layer or ceramic layer is 10 and the distance between dielectric layers is 1, the distance between the centers of the H roller head and the K roller head can be set to (11+22n, n>=0, and n is an integer).

[0052] The cross-cutting knife 13 structure and the vertical cutting knife structure 3 of the MLCC lamination device of the present invention do not need to move left and right or up and down; when cutting, the dielectric layer or ceramic layer is directly laminated on the lamination table without pre-pressing, thereby avoiding time waste and improving cutting efficiency; in addition, because the contact surface between the lamination table and the cross-cutting knife 13 structure is an arc surface, gas cannot be discharged, bubbles are not generated after lamination, and the lamination quality and product performance are not affected.

[0053] The above is only a preferred embodiment of the present invention. 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 invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
