Description

Technical Field

[0001] This utility model relates to the field of inductor manufacturing technology, and in particular to an inductor tape coating equipment. Background Technology

[0002] Miniature inductors are devices that can convert electrical energy into magnetic energy and store it. The structure of an inductor is similar to a transformer, but it has only one winding. An inductor has a certain inductance; it only impedes changes in current. A single inductor is like... Figure 10 As shown, it has a base and two pins.

[0003] After manufacturing small inductor components, they need to be connected in series for easy transport and subsequent use. This is typically done by using tape to attach the leads on both sides of the inductor component one by one, thus connecting the inductors in series. After series connection, as shown... Figure 10 As shown. Traditionally, this is a manual process. First, the adhesive side of the tape is laid flat, then the inductor components are placed one by one, and then another layer of tape is applied with the adhesive side down. This coating process is inefficient, and manual operation results in uneven spacing between adjacent inductor components, making it inconvenient to retrieve them later. Therefore, how to efficiently coat inductor components and neatly collect them after coating is a problem that those skilled in the art need to consider. Utility Model Content

[0004] The purpose of this invention is to provide an inductor tape coating device to solve the problems of low coating efficiency and uneven coating of inductor components in the prior art.

[0005] The technical solution of this utility model is: an inductor component tape coating device, comprising:

[0006] The feeding mechanism includes a first material tray bin, a first receiving bin bin, a first driving device connecting the first material tray bin and the first receiving bin bin, and a pushing component disposed between the first material tray bin and the first receiving bin bin. The first driving device drives the material tray in the first material tray bin to the first receiving bin bin, while the pushing component pushes the inductive element in the material tray to the coating mechanism.

[0007] The coating mechanism includes a coating component connected to the pushing component, a first feeding component and a second feeding component respectively disposed above and below the coating component. The coating component includes a first coating wheel and a second coating wheel tangentially connected to the first coating wheel. An inductive element enters between the first coating wheel and the second coating wheel. The tape at the first feeding component passes around the first coating wheel from top to bottom and is attached to the inductive element. The tape at the second feeding component passes around the second coating wheel from bottom to top and is attached to the inductive element.

[0008] The feeding mechanism includes a second material tray bin, a second receiving bin bin, a second drive device connecting the second material tray bin and the second receiving bin bin, and a material pulling assembly disposed between the second material tray bin and the second receiving bin bin. The second drive device drives the material tray in the second material tray bin to the second receiving bin bin. At the same time, the material pulling assembly pulls the coated inductor element into the material tray.

[0009] When the first rubber-coated wheel rotates, it drives the inductor to transmit data, and the speed at which the first rubber-coated wheel drives the inductor to transmit data is greater than the speed at which the pusher assembly drives the inductor to transmit data.

[0010] Preferably, the pushing assembly includes a pushing module, a pushing plate connected to the pushing module via a third driving device with a vertical driving direction, and a feeding track with a feeding groove. The pushing module drives an inductive element to move within the feeding groove via the pushing plate.

[0011] The feed track is connected to the rubber coating assembly.

[0012] Preferably, a limiting plate is provided on the feeding track, and the limiting plate partially covers the feeding trough.

[0013] Preferably, the first rubber-coated wheel has an annular first clearance groove at its center, and a first pressing part is formed on both sides of the first clearance groove; the second rubber-coated wheel has an annular second clearance groove at its center, and a second pressing part is formed on both sides of the second clearance groove.

[0014] Preferably, the first feeding assembly includes a first guide wheel group and two first feeding rollers, and the tape on the two first feeding rollers respectively wraps around the first guide wheel group and is connected to the first pressing part;

[0015] The second feeding assembly includes a second guide wheel assembly and two second feeding rollers, with the tape on the two second feeding rollers respectively passing around the second guide wheel assembly and being wound around the second pressing part.

[0016] Preferably, the rubber coating assembly includes a first bracket and a first connecting rod connected to the first rubber coating wheel. The first connecting rod is rotatably connected to the first bracket, and the end of the first connecting rod away from the first rubber coating wheel is connected to the upper end of the first bracket through a first spring.

[0017] The first spring pulls the first connecting rod, causing the first connecting rod to have a rotational tendency on the first bracket, which in turn causes the first rubber-coated wheel to have a rotational tendency and press against the second rubber-coated wheel.

[0018] Preferably, the coating mechanism further includes a pressing assembly, which is connected to the coating assembly via a transmission rail. The pressing assembly includes a first pressing wheel and a second pressing wheel tangentially connected to the first pressing wheel, and the coated inductor is connected between the first pressing wheel and the second pressing wheel.

[0019] Preferably, the material pulling assembly includes a material pulling module, a material carrier plate disposed below the material pulling module, and a material unloading device fixedly connected to the material pulling module. The material pulling module is connected to a gripper device, which is disposed above the material carrier plate.

[0020] The feeding device includes a fifth driving device fixedly connected to the feeding module and a feeding push plate connected to the fifth driving device. The feeding push plate is disposed above the carrying plate.

[0021] The fifth driving device drives the feeding pusher plate to move, so as to push the inductor components on the carrier plate to be fed out.

[0022] Preferably, a cutting component is provided on the side of the material pulling component near the coating mechanism.

[0023] The end of the feeding track is equipped with a cutter and an eighth driving device for driving the cutter to move vertically.

[0024] Compared with the prior art, the advantages of this utility model are:

[0025] (1) When the rotation speed of the first coating wheel is uniform and greater than the conveying speed of the pusher assembly, the inductor element enters the coating mechanism from the feeding track for coating. Through the speed difference, the adjacent inductor elements that are connected to each other at the feeding track can be separated one by one and evenly arranged for coating.

[0026] (2) The entire process of feeding, coating and unloading after coating is completed automatically, which greatly improves production efficiency and reduces labor costs. Attached Figure Description

[0041] Inductor 4, substrate 41, pin 42, tape 43. Detailed Implementation

[0042] The present invention will be further described in detail below with reference to specific embodiments:

[0043] like Figure 1-10 As shown, this is applied to the coating of inductor components. A tray containing inductor components is placed in the first tray compartment 11. The inductor components are loaded at the loading mechanism 1; the coating is completed at the coating mechanism; and at the unloading mechanism, the coated inductor components are cut and placed one by one into the tray. Specifically:

[0044] like Figures 1-2 As shown, the feeding mechanism 1 includes a first material tray 11, a first receiving tray 12, a first driving device 13 connecting the first material tray 11 and the first receiving tray 12, and a pushing component 14 disposed between the first material tray 11 and the first receiving tray 12. The first driving device 13 drives the material tray in the first material tray 11 to the first receiving tray 12, while the pushing component 14 pushes the inductor in the material tray to the coating mechanism 2.

[0045] The feeding assembly 14 includes a feeding module 141, a feeding plate 143 connected to the feeding module 141 via a third driving device 142 with a vertical driving direction, and a feeding track 144 with a feeding groove 1441. The feeding module 141 drives an inductive element to move within the feeding groove 1441 via the feeding plate 143. A limiting plate 1442 is provided on the feeding track 144, and the limiting plate 1442 partially covers the feeding groove 1441.

[0046] In this embodiment, multiple trays carrying inductor components are stacked in the first tray bin 11, and empty trays are stacked one by one in the first receiving tray bin 12. The process of the bottommost tray moving downwards in the first tray bin 11 is prior art, and similarly, the process of stacking the trays upwards in the first receiving tray bin 12 is also prior art, and will not be described in detail in this embodiment.

[0047] During the process of the first driving device 13 driving the material tray to move towards the first receiving bin 12, the movement is gradual. Each movement causes each group of inductors on the material tray to connect sequentially to the feeding slot 1441. During feeding, the third driving device 142 drives the pusher plate 143 downwards, and the pusher module 141 drives the pusher plate 143 to contact the inductors in the material tray and push them into the feeding slot 1441. The limiting plate 1442 is designed to prevent the inductors from detaching from the feeding slot 1441 due to mutual compression during feeding.

[0048] like Figures 3-5As shown, the coating mechanism 2 includes a coating component 21 connected to the feeding component 14, a first feeding component 22 and a second feeding component 23 respectively disposed above and below the coating component 21. The coating component 21 includes a first coating wheel 211 and a second coating wheel 212 tangentially connected to the first coating wheel 211. The inductor enters between the first coating wheel 211 and the second coating wheel 212. The tape at the first feeding component 22 passes around the first coating wheel 211 from top to bottom and is attached to the inductor. The second feeding component 23 passes around the second coating wheel 212 from bottom to top and is attached to the inductor.

[0049] The first rubber-coated wheel 211 has an annular first clearance groove 2111 at its center, and a first pressing part 2112 is formed on both sides of the first clearance groove 2111; the second rubber-coated wheel 212 has an annular second clearance groove 2121 at its center, and a second pressing part 2122 is formed on both sides of the second clearance groove 2121.

[0050] The first feeding assembly 22 includes a first guide wheel group 221 and two first feeding rollers 222. The tape on the two first feeding rollers 222 respectively wraps around the first guide wheel group 221 and is connected to the first pressing part 2112. The second feeding assembly 23 includes a second guide wheel group 231 and two second feeding rollers 232. The tape on the two second feeding rollers 232 respectively wraps around the second guide wheel group 231 and is connected to the second pressing part 2122. Both the first guide wheel group 221 and the second guide wheel group 231 contain multiple guide wheels to limit the tape transmission and prevent tape deviation. The tape in the two first feeding rollers 222 is respectively attached to the upper ends of the leads on both sides of the inductor element; the tape in the two second feeding rollers 232 is respectively attached to the lower ends of the leads on both sides of the inductor element.

[0051] In this embodiment, a drive motor (not shown in the figure) is connected to the first coating roller 211. When the first coating roller 211 rotates, it drives the first feeding roller 222 and the second feeding roller 232 to feed the tape. The linear velocity of the first coating roller 211 driven by the drive motor is greater than the speed at which the pushing assembly 14 pushes the inductor element in the feed groove 1441, so that the inductor element is accelerated when it enters the coating assembly 21, thereby making the coated inductor elements arranged at intervals. In addition, the rotation speed of the first coating roller 211 is set uniformly so that the interval between two adjacent inductor elements after coating is consistent.

[0052] During the encapsulation process, the substrate of the inductor element passes between the first clearance groove 2111 and the second clearance groove 2121, while the leads on both sides are transferred between the first pressing part 2112 and the second pressing part 2122 on both sides, respectively. The adhesive tape is wrapped around the first pressing part 2112 and the second pressing part 2122, respectively. Therefore, the encapsulation of the leads on both sides is completed simultaneously with the transfer.

[0053] To further ensure the stability of the adhesive application during the coating process, the coating assembly 21 is also provided with a first bracket 213 and a first connecting rod 2131 connected to the first coating wheel 211. The first connecting rod 2131 is rotatably connected to the first bracket 213, and the end of the first connecting rod 2131 away from the first coating wheel 211 is connected to the upper end of the first bracket 213 via a first spring 2132. The first spring 2132 pulls the first connecting rod 2131, causing the first connecting rod 2131 to have a rotational tendency on the first bracket 213. Consequently, the first coating wheel 211 has a rotational tendency and presses against the second coating wheel 212, resulting in a large clamping force between the first pressing part 2112 and the second pressing part 2122 during the coating process.

[0054] The coating mechanism 2 also includes a pressing assembly 24, which is connected to the coating assembly 21 via a transmission rail 25. The pressing assembly 24 includes a first pressing roller 241 and a second pressing roller 242 tangentially connected to the first pressing roller 241. The coated inductor is located between the first pressing roller 241 and the second pressing roller 242.

[0055] In this embodiment, after the overmolding is completed, the inductor element is further pressed between the first pressing roller 241 and the second pressing roller 242 to ensure the stability of the overmolding bonding. The structure of the pressing assembly 24 is basically the same as that of the overmolding assembly 21, and will not be described again here.

[0056] like Figures 6-8 As shown, the feeding mechanism 3 includes a second material tray 31, a second receiving tray 32, a second driving device 33 connecting the second material tray 31 and the second receiving tray 32, and a material pulling assembly 34 disposed between the second material tray 31 and the second receiving tray 32. The second driving device 33 drives the material tray in the second material tray 31 to the second receiving tray 32, while the material pulling assembly 34 pulls the coated inductor components into the material tray. The second material tray 31 completes the feeding of empty material trays, and the second receiving tray 32 completes the receiving of material trays containing inductor components. Its structure and movement process are existing technologies and will not be described in detail in this embodiment. The second driving device 33 drives the material tray in a step-by-step manner, sequentially positioning the material slots on the material tray below the carrier plate, thereby allowing the inductor components on the carrier plate to be pushed into the carrier plate.

[0057] The material pulling assembly 34 includes a material pulling module 341, a carrier plate 342 disposed below the material pulling module 341, and a material unloading device 343 fixedly connected to the material pulling module 341. A gripper device 3411 is connected to the material pulling module 341 and is positioned above the carrier plate 342. The material pulling module 341 can use the gripper device 3411 to grasp the coated inductor components and move them onto the carrier plate 342. The material unloading device 343 includes a fifth drive device 3431 fixedly connected to the material pulling module 341 and a material unloading push plate 3432 connected to the fifth drive device 3431. The material unloading push plate 3432 is positioned above the carrier plate 342. The fifth drive device 3431 drives the material unloading push plate 3432 to move, thereby pushing the inductor components on the carrier plate 342 to be unloaded.

[0058] A cutting assembly 35 is provided on the side of the feeding assembly 34 near the overmolding mechanism 2. The cutting assembly 35 includes a sixth driving device 351 with a horizontal driving direction and a feeding track 352 connected to the sixth driving device 351. The feeding track 352 is connected to a pressure block 354 through a seventh driving device 353 with a vertical driving direction. A cutter 355 and an eighth driving device 356 are provided at the end of the feeding track 352 to drive the cutter 355 to move vertically are provided.

[0059] In this embodiment, the coated inductor moves to the cutter 355 via the feeding track 352. The gripper device 3411 grips the inductor at the cutter 355 and pulls it a preset distance under the drive of the pulling module 341, so that the coated inductor is placed on the carrier plate 342. The seventh drive device 353 drives the pressure block 354 to press down on the inductor to fix it, while the eighth drive device 356 drives the cutter 355 to cut it. At this time, the cut inductor is completely placed on the carrier plate 342, and the fifth drive device 3431 pushes the inductor into the tray via the feeding push plate 3432. During the cutting, the tape between two adjacent inductors is cut. After cutting, the sixth drive device 351 drives the feeding track 352 to move towards the cutter 355, so that the inductor on the feeding track 352 passes through the cutter 355, so that the gripper device 3411 can grip it again.
