Description

Technical Field

[0001] This invention relates to the field of magnetic powder core processing technology, and in particular to an automatic dispensing device for magnetic powder cores. Background Technology

[0002] Magnetic powder cores are made by coating a layer of insulating material onto the surface of soft magnetic metal particles and then pressing them together using specific processes. They are also known as soft magnetic composite materials. Magnetic powder cores have low permeability but good linearity and a wide operating frequency range, making them extremely important for the development of high-performance inductor products.

[0003] When manufacturing an inductor, the bonding surfaces of the upper and lower magnetic powder cores in the inductor need to be connected with adhesive. The traditional method of dispensing adhesive is to first apply adhesive manually to the bonding surface of one magnetic powder core, and then manually attach the other magnetic powder core to the adhesive-coated magnetic powder core.

[0004] If manual bonding is not timely during the dispensing process, the adhesive will become ineffective due to the long coating time. Moreover, since there are precise requirements for the relative position, fitting gap, and adhesive layer thickness after the upper and lower magnetic powder cores are firmly bonded, the processing personnel need to precisely control the applied force to adjust the inductance to the target value. However, this will inevitably lead to low processing efficiency and make it difficult to ensure process consistency, resulting in inconsistent inductance. Summary of the Invention

[0005] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes an automatic dispensing device for magnetic powder cores, which can realize the function of automatic dispensing of upper and lower magnetic powder cores in inductors, thereby improving processing efficiency and maintaining process consistency.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] An automatic dispensing device for magnetic powder cores includes a first conveying component, a dispensing table, and a second conveying component. The first conveying component is used to convey magnetic powder cores to be bonded. The dispensing table is located on the output side of the first conveying component and includes a gripping mechanism, a flipping mechanism, a dispensing mechanism, and a bonding mechanism. The gripping mechanism is used to grip the magnetic powder cores supported on the first conveying component and transfer them to the flipping mechanism and the dispensing mechanism. The flipping mechanism is used to flip the magnetic powder cores supported on it in the opposite direction. The bonding mechanism is used to bond the magnetic powder cores that have been coated with adhesive on the dispensing mechanism and the flipped magnetic powder cores on the flipping mechanism to each other. The second conveying component is located on one side of the dispensing table and its input side is close to the bonding mechanism. It is used to convey the magnetic powder core bonding body transferred from the bonding mechanism.

[0008] In addition, the automatic dispensing device for magnetic powder cores according to the present invention may also have the following additional technical features:

[0009] Furthermore, the flipping mechanism includes a drive base, a flipping claw, a first positive mounting support platform, and a reverse mounting support platform. The flipping claw is rotatably connected to the drive base. The first positive mounting support platform and the reverse mounting support platform are respectively located on opposite sides of the rotation path of the flipping claw. When the flipping claw is not flipped, it is attached to the top of the first positive mounting support platform. After the flipping claw is flipped, it is attached to the top of the reverse mounting support platform.

[0010] Furthermore, the gripping mechanism includes a first robotic arm and a first visual positioning device. The first robotic arm is equipped with a detachable first clamping member that is adapted to the shape and size of the magnetic powder core. The first visual positioning device is located on the first clamping member. There is an active space between the first robotic arm and the output side of the first conveying component, the first mounting support platform, and the dispensing mechanism, so as to enable the first clamping member and the first visual positioning device to move freely within this active space.

[0011] Furthermore, the dispensing mechanism includes a second robotic arm, a second vision positioning device, a dispensing component, and a second mounting support platform. The second robotic arm is equipped with a detachable second clamping component that is adapted to the shape and size of the magnetic powder core. The second vision positioning device is mounted on the second clamping component. There is a space between the second robotic arm and the second mounting support platform to allow the second clamping component and the second vision positioning device to move freely within this space. The dispensing component is configured to dispense adhesive onto the bonding surface of the magnetic powder core on the second mounting support platform using a matching coating model based on the image information obtained by the second vision positioning device.

[0012] Furthermore, the dispensing component includes a needle-type dispensing valve, a pressure tank, and an air compressor. The needle-type dispensing valve is fixed to the second clamping component. The discharge port of the pressure tank is connected to the inlet port of the needle-type dispensing valve, and the air outlet of the air compressor is connected to the air inlet port of the pressure tank.

[0013] Furthermore, the bonding mechanism includes a third robotic arm, a third mounting support platform, and a shaping and pressing mechanism. The third robotic arm is equipped with a detachable third clamping member that is adapted to the shape and size of the magnetic powder core. There is a space for movement between the third robotic arm and the third mounting support platform to allow the third clamping member to move freely within this space. The third mounting support platform is equipped with retractable fourth clamping members on opposite sides. The shaping and pressing mechanism is used to press the magnetic powder core bonded body up and down.

[0014] Furthermore, the shaping and pressing mechanism includes a telescopic cylinder, a rotating shaft, a support arm, and a hammer. The telescopic cylinder is mounted on the third positive mounting support platform, the rotating shaft is sleeved inside the telescopic cylinder, one end of the support arm is fixed to the rotating shaft, and the end of the support arm away from the rotating shaft is provided with a hammer.

[0015] Furthermore, the automatic dispensing device for magnetic powder cores also includes a drying device, which has a baking channel through which the magnetic powder core adhesive on the second conveying assembly passes.

[0016] Furthermore, the first conveying assembly includes a first conveyor platform and a first conveyor belt, with the first conveyor belt horizontally positioned on the first conveyor platform.

[0017] Furthermore, the second conveying assembly includes a second conveyor platform and a second conveyor belt, the second conveyor belt being horizontally disposed on the second conveyor platform.

[0018] This invention has the following beneficial effects: A gripping mechanism grips a first magnetic powder core and places it on a dispensing mechanism. A flipping mechanism then flips a second magnetic powder core in the opposite direction. After dispensing the first magnetic powder core, a bonding mechanism first places the first magnetic powder core supported by the dispensing mechanism onto a bonding mechanism. Then, the bonding mechanism vertically places the flipped second magnetic powder core onto the bonding surface of the first magnetic powder core and extrudes it for shaping. Once the two magnetic powder cores are bonded together to form a magnetic powder core bond, the bonding mechanism further secures the magnetic powder cores. The assembly is transferred to the second conveying component on one side of the dispensing station. By repeating the above actions, automatic dispensing of batches of magnetic powder cores can be achieved. Compared with manual dispensing, the dispensing efficiency is higher. At the same time, since the relative position, mating gap, and adhesive layer thickness of the two magnetic powder cores can be precisely controlled by these mechanical components, the consistency of the process during dispensing is ensured, thereby improving the quality of the magnetic powder core bonded body. In addition, the gripping, flipping, and dispensing operations of the magnetic powder cores can be performed in an alternating manner, which further improves the dispensing efficiency compared with manual dispensing.

Detailed Implementation

[0029] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of the invention are illustrated in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0030] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] refer to Figures 1 to 8This invention provides an automatic dispensing device for magnetic powder cores, comprising a first conveying component 100, a dispensing table 300, and a second conveying component 400. The first conveying component 100 is located to the left of the dispensing table 300 and is used to continuously convey magnetic powder cores to be bonded to the dispensing table 300. The dispensing table 300 is used to continuously dispense and bond the opposing bonding surfaces of two magnetic powder cores. The second conveying component 400 is located to the right of the dispensing table 300 and is used to continuously convey the magnetic powder core bonded body formed after dispensing and bonding.

[0033] The dispensing table 300 includes a gripping mechanism 310, a flipping mechanism 320, a dispensing mechanism 330, and a bonding mechanism 340. In use, the gripping mechanism 310 sequentially grips the magnetic powder core supported on the first conveying component 100 and places it onto the flipping mechanism 320 and the dispensing mechanism 330. Since glue is needed to bond the bonding surfaces of the two magnetic powder cores, after the gripping mechanism 310 grips the first magnetic powder core and places it on the dispensing mechanism 330, the flipping mechanism 320 needs to flip the second magnetic powder core it supports in the opposite direction. After the dispensing mechanism 330 dispenses glue onto the first magnetic powder core, the bonding mechanism 340 first places the first magnetic powder core supported on the dispensing mechanism 330 onto the bonding mechanism 340. Then, the bonding mechanism 340 vertically places the second magnetic powder core, which has been flipped in the opposite direction on the flipping mechanism 320, onto the bonding surface of the first magnetic powder core and extrudes and shapes it. After two magnetic powder cores are bonded together to form a magnetic powder core bond, the bonding mechanism 340 transfers the magnetic powder core bond to the second conveying assembly 300 on one side of the dispensing station 200. By repeating the above actions, automatic dispensing of batches of magnetic powder cores can be achieved.

[0034] In this embodiment, because the gripping mechanism 310, flipping mechanism 320, dispensing mechanism 330, and bonding mechanism 340 each have their own tasks and cooperate, they can work continuously and in parallel. For example, when the dispensing mechanism 330 is dispensing glue to the first magnetic powder core, the gripping mechanism 310 can grip the second magnetic powder core onto the flipping mechanism 320. Similarly, when the bonding mechanism 340 is in operation, the dispensing mechanism 330 can dispense glue to the third magnetic powder core, and the flipping mechanism 320 can then flip the fourth magnetic powder core in the opposite direction. Compared to manual dispensing, this method is highly automated, thus greatly improving dispensing efficiency. Furthermore, since the relative position, gap, and adhesive layer thickness of the two bonded magnetic powder cores can be precisely controlled mechanically, the consistency of the process during dispensing is effectively ensured, thereby improving the quality of the bonded magnetic powder cores.

[0035] In some alternative embodiments, such as Figure 2As shown, the flipping mechanism 320 includes a drive base 321, a flipping claw 322, a first positive mounting support platform 323, and a reverse mounting support platform 324. The flipping claw 322 is rotatably connected to the drive base 321, so that the flipping claw 322 can rotate under the drive of the drive base 321. Optionally, the drive base 321 can use a motor or cylinder as the drive source and be connected to the flipping claw 322 through a shaft. The first positive mounting support platform 323 and the reverse mounting support platform 324 are respectively located on opposite sides of the rotation path of the flipping claw 322. Taking the E-type magnetic powder core as an example, when in use, the gripping mechanism 310 grips the two sides of the E-type magnetic powder core and places its bottom surface flat on the first positive mounting support platform 323. Then, the flipping claw 322, which is attached to the top of the first positive mounting support platform 323, grips the two sides of the E-type magnetic powder core and rotates it as a whole. When the flipping claw 322 is attached to the top of the reverse mounting support platform 324, the adhesive surface of the E-type magnetic powder core contacts the table surface of the reverse mounting support platform 324. Then, the flipping claw 322 rotates in the opposite direction and stops on the top of the first positive mounting support platform 323, and continues to flip the next E-type magnetic powder core in the opposite direction.

[0036] It should be noted that, since the bonding surfaces of different magnetic powder cores have different shapes, and in order to stably place the bonding surfaces of the magnetic powder cores on the table surface of the reverse mounting support 324, the table surface of the reverse mounting support 324 can be set to a corresponding shape and size according to the outer dimensions of the bonding surfaces of the magnetic powder cores, so that the bonding surfaces of the magnetic powder cores will not move horizontally on the table surface of the reverse mounting support 324. For example, for E-type magnetic powder cores, the table surface of the reverse mounting support 324 can be processed into a shape with convex ends and concave middle, so that the central column of the E-type magnetic powder core is nested in the concave middle, thereby preventing the E-type magnetic powder core from moving horizontally.

[0037] In some alternative embodiments, such as Figure 4 As shown, the gripping mechanism 310 includes a first robotic arm 311 and a first visual positioning device 312. The first robotic arm 311 is equipped with a detachable first clamping member 3111 that is adapted to the shape and size of the magnetic powder core. The first visual positioning device 312 is mounted on the first clamping member 3111. Specifically, the first visual positioning device 312 can be a camera with image recognition function. During installation, the camera lens is placed side by side with the first clamping member 3111, and the two are aligned in the same direction. There is a space for movement between the first robotic arm 311 and the output side of the first conveying assembly 100, the mounting support platform, and the dispensing mechanism, so that the first clamping member 3111 and the first visual positioning device 312 can move freely within this space. Considering cost and installation space, preferably, the first robotic arm 311 is a four-axis robotic arm, that is, it can move along four dimensions: up and down, left and right, forward and backward, and rotation.

[0038] In this embodiment, since the magnetic powder cores supported on the first conveying assembly 100 may be unevenly distributed, the position of the magnetic powder core to be grasped is accurately located based on the image information obtained by the first visual positioning device 312, thereby causing the first robotic arm 311 to move and the first gripper 3111 to accurately grasp the magnetic powder core. Similarly, the position of the table surface of the first mounting support platform 323 is accurately located based on the image information obtained by the first visual positioning device 312, so that the grasped magnetic powder core is accurately placed on the table surface of the first mounting support platform 323. In addition, since the first gripper 3111 is detachably mounted on the first robotic arm 311, when it is necessary to apply adhesive to magnetic powder cores of other shapes, the first gripper 3111 with matching dimensions can be replaced, making the device more versatile and facilitating maintenance operations.

[0039] In some alternative embodiments, such as Figure 2 As shown, the dispensing mechanism 330 includes a second robotic arm 331, a second visual positioning device 334, a dispensing component 335, and a second mounting support platform 336. The second robotic arm 331 is equipped with a detachable second clamping component 3311 that is adapted to the shape and size of the magnetic powder core. The second visual positioning device 334 is mounted on the second clamping component 3311. Specifically, the second visual positioning device 334 can be a camera with image recognition function. During installation, the camera lens is placed side by side with the second clamping component 3311, and the two are aligned in the same direction. There is a space for movement between the second robotic arm 331 and the second mounting support platform 336 to allow the second clamping component 3311 and the second visual positioning device 334 to move freely within this space. During dispensing, since the magnetic powder cores include two shapes, ring-shaped and irregular, and the dispensing position, glue dot shape, and distribution are different for magnetic powder cores of different shapes and sizes, different coating models need to be matched to ensure the consistency of the dispensing process and the consistency of the inductance of the magnetic powder core adhesive. Based on this, the dispensing component 335 is configured to dispense adhesive onto the bonding surface of the magnetic powder core on the second mounting support 336 using a matching coating model, based on the image information acquired by the second visual positioning device 334. Taking an E-type magnetic powder core as an example, it is preferable to apply the adhesive to the bonding surface of the magnetic powder core at multiple points and to coat the adhesive dots in a hemispherical shape. When a single adhesive dot is flattened, due to the compression and mutual restriction of the surrounding adhesive, the final filled area can be approximated as a thin sheet with a square projected area.

[0040] Furthermore, considering cost and installation space, in this embodiment, the second robotic arm 331 is preferably a four-axis robotic arm, meaning it can move along four dimensions: up and down, left and right, forward and backward, and rotation. Moreover, since the second gripper 3311 is detachably mounted on the second robotic arm 331, when dispensing magnetic powder cores of other shapes is required, the second gripper 3311 with a matching external dimension can be replaced, making the device more versatile and facilitating maintenance. This example, by setting a second visual positioning device 334, can accurately grasp and place the magnetic powder core. Simultaneously, based on the image information acquired by the second visual positioning device 334, the external dimensions of the magnetic powder core can be accurately identified to dispense the magnetic powder core according to the matching coating model, thereby ensuring the consistency of the dispensing process for different magnetic powder cores and maintaining consistent inductance of the adhesive bodies for different magnetic powder cores.

[0041] In some alternative embodiments, such as Figure 2 , 6 As shown, the dispensing component 335 includes a needle-type dispensing valve 3351, a pressure tank 3352, and an air compressor (not shown in the attached drawings). The needle-type dispensing valve 3351 is fixedly mounted on the second clamping component 3311. The pressure tank 3352 contains adhesive. The discharge port of the pressure tank 3352 is connected to the inlet port of the needle-type dispensing valve 3351. The air outlet of the air compressor is connected to the air inlet port of the pressure tank 3352. When in use, the glue is loaded into the pressure tank 3352. The air compressor is turned on to allow compressed air to enter the pressure tank 3352. The high-pressure air forces the glue in the pressure tank 3352 through the pipe into the material cylinder (not shown in the attached drawing) of the needle-type dispensing valve 3351. At this time, an opening signal is sent to the solenoid valve (not shown in the attached drawing) of the needle-type dispensing valve 3351, thereby driving the piston in the needle-type dispensing valve 3351 to move downward. The glue is then squeezed out from the needle of the needle-type dispensing valve 3351 through the material cylinder. During this process, the amount of adhesive dispensed by the needle of the needle-type dispensing valve 3351 is determined by three factors: the control time of the solenoid valve, the air pressure of the pressure tank 3352, and the stroke of the piston. This allows the shape and size of the magnetic powder core on the second mounting support 336 to be determined based on the image information obtained by the second vision positioning device 334. This, in turn, controls the running path of the needle-type dispensing valve 3351, the solenoid valve time of the needle-type dispensing valve 3351, the air pressure of the pressure tank 3352, and the stroke of the piston. This enables the magnetic powder core to be dispensed with a matching coating model, ensuring consistency in the dispensing process and maintaining consistent inductance of the magnetic powder core adhesive.

[0042] In some alternative embodiments, such as Figure 6 , 8As shown, the bonding mechanism 340 includes a third robotic arm 341, a third mounting support platform 342, and a shaping and pressing mechanism 343. The third robotic arm 341 is equipped with a detachable third clamping member 3411 that is adapted to the shape and size of the magnetic powder core. There is a space between the third robotic arm 341 and the third mounting support platform 342 to allow the third clamping member 3411 to move freely within this space. In addition, the third mounting support platform 342 is equipped with retractable fourth clamping members 3421 on opposite sides. When the third clamping member 3411 places the magnetic powder core that has been flipped in the reverse direction on the flipping mechanism 320 onto the magnetic powder core that has been glued, the fourth clamping member 3421 retracts towards the magnetic powder core adhesive body, thereby fixing the position of the magnetic powder core adhesive body and preventing its position from shifting. Since the adhesive cannot be applied to the bonding surface between the two magnetic powder cores in one extrusion, a certain frequency of longitudinal pressure is required, i.e., multiple extrusions are needed to achieve the target air gap and inductance. Therefore, a shaping and pressing mechanism 343 is set up to press the magnetic powder core adhesive body from top to bottom, ensuring that the adhesive between the two magnetic powder cores completely fills the bonding surface and achieves good adhesion.

[0043] In this embodiment, considering cost and installation space, the third robotic arm 341 is preferably a four-axis robotic arm, meaning it can move along four dimensions: up and down, left and right, forward and backward, and rotation. Furthermore, since the third clamping member 3411 is detachably mounted on the third robotic arm 341, when it is necessary to clamp magnetic powder cores of other shapes, a third clamping member 3411 matching its dimensions can be used, making the device more versatile and facilitating maintenance.

[0044] In some alternative embodiments, such as Figure 8As shown, the shaping and pressing mechanism 343 includes a telescopic cylinder 3431, a rotating shaft 3432, a support arm 3433, and a hammer head 3434. The telescopic cylinder 3431 is fixedly installed on the third positive support platform 342. The rotating shaft 3432 is sleeved inside the telescopic cylinder 3431. One end of the support arm 3433 is fixedly installed on the rotating shaft 3432. The end of the support arm 3433 away from the rotating shaft 3432 is provided with a hammer head 3434. Before the bonding mechanism 340 completes the bonding operation on the magnetic powder core supported on the third mounting support 342, in order to avoid affecting the operation of the bonding mechanism 340, the support arm 3433 and the hammer head 3434 are rotated to one side of the third mounting support 342 via the rotating shaft 3432. After the bonding mechanism 340 completes the bonding operation on the magnetic powder core supported on the third mounting support 342, the support arm 3433 and the hammer head 3434 are rotated to the top of the magnetic powder core bonding body via the rotating shaft 3432. Then, the telescopic cylinder 3431 moves vertically up and down at a certain frequency, so that the hammer head 3434 regularly hammers the surface of the magnetic powder core bonding body. At the same time, the distribution of the hammering points and the hammering force are determined according to the different shapes and sizes of the magnetic powder cores, so as to ensure that the glue between the two magnetic powder cores completely fills the bonding surface and achieves good bonding.

[0045] In some alternative embodiments, such as Figure 3 As shown, the automatic magnetic powder core dispensing device also includes a drying device 500, which has a baking channel 510 through which the magnetic powder core adhesive on the second conveying assembly 400 passes. In this embodiment, the magnetic powder core adhesive, which has been bonded and shaped on the third mounting support 342, is first clamped onto the second conveying assembly 400 by the third robotic arm 341. When the second conveying assembly 400 conveys the magnetic powder core adhesive into the baking channel 510, the magnetic powder core adhesive can be baked, allowing the adhesive to solidify quickly. Then, the magnetic powder core adhesive is conveyed to the next station by the second conveying assembly 400, thus completing the dispensing process of the first magnetic powder core adhesive.

[0046] In some alternative embodiments, such as Figure 1 As shown, the first conveying assembly 100 includes a first conveyor platform 110 and a first conveyor belt 120. The first conveyor belt 120 is horizontally arranged on the first conveyor platform 110. Optionally, the first conveyor belt 120 can continuously convey a tray containing multiple magnetic powder cores to the dispensing machine 200, or, on its input side, the magnetic powder cores on the tray can be sequentially placed onto the first conveyor belt 120 by manual labor or a robotic arm. It is understood that the first conveying assembly 100 can also use other conveying mechanisms, not limited to a conveyor belt, such as conveyor rollers or linear motor modules.

[0047] In some alternative embodiments, such as Figure 1As shown, the second conveying assembly 400 includes a second conveyor platform 410 and a second conveyor belt 420. The second conveyor belt 420 is horizontally arranged on the second conveyor platform 410. Optionally, the second conveyor belt 420 can continuously convey a tray containing multiple magnetic powder cores to the dispensing machine 200, or, on its input side, the magnetic powder cores on the tray can be sequentially placed onto the second conveyor belt 420 by manual labor or a robotic arm. It is understood that the second conveying assembly 400 can also use other conveying mechanisms, not limited to a conveyor belt, such as conveyor rollers or linear motor modules.

[0048] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
