Description

Technical Field

[0001] This invention relates to the field of capacitor manufacturing technology, and more specifically to a capacitor core conveying and feeding device. Background Technology

[0002] The capacitor core is the core energy storage component of a capacitor. The processing of capacitor cores includes processes such as cutting, riveting, winding, shaping, and gold spraying. Among these, the feeding process is the initial preparation stage of the winding process and is a preliminary step before the winding process. The feeding stage is responsible for organizing the capacitor cores produced by the winding machine from a messy state into a uniform and orderly queue, and then conveying them to the main body of the assembly machine for subsequent processes such as sleeve, sealing, and assembly.

[0003] Currently, existing equipment for core feeding, such as the "LKQPJ-20B Intelligent Chip Precision Arrangement Machine," mainly consists of a hopper, a vibratory feeder, and a guide rail. The core falls from the hopper into the vibratory feeder, where it is sorted by vibration. The vibratory feeder arranges the core into the circumferential rail for easy subsequent processing.

[0004] In actual operation, feeding requires conveying the coil core from the hopper to the vibratory feeder. Since traditional hoppers are usually located above the vibratory feeder, the coil core falls from the hopper into the feeder by gravity. During feeding, because the coil core is only made of thin metal, it is prone to deformation and damage due to contact and collision between the coil cores or with the inner wall of the vibratory feeder. Simultaneously, after the coil core falls to the bottom of the vibratory feeder, it disperses in all directions under the vibration of the feeder. The dispersed coil core needs to move along the inner wall of the vibratory feeder to align and enter the rising track. Because the bottom of a traditional vibratory feeder is usually flat or conical, its dispersion principle mainly relies on the radial driving force provided by the component of the coil core's own gravity along the inclined surface; the vibratory feeder only plays an auxiliary disturbance role. Since the magnitude of the gravity component is limited by the angle of the conical surface and its direction is fixed, it is difficult to form an effective dispersion effect across the entire area of ​​the vibratory feeder surface. This results in a large degree of randomness and lag in the movement path of the coil core at the bottom of the feeder, leading to a long alignment time and limiting feeding efficiency.

[0005] Therefore, the present invention provides a capacitor core conveying and feeding device to solve the above problems. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a capacitor core conveying and feeding device, which solves the problems of damage caused by gravity-induced impacts during the existing core feeding process and the easy alignment deviation caused by the planar arrangement of the vibratory feeder.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows: A capacitor core conveying and feeding device includes a hopper and a vibratory plate. A base is fixedly connected to the bottom of the vibratory plate, and a feeding track is connected to the bottom of the hopper. The other end of the feeding track is connected to the side wall of the base. A rotating shaft is rotatably connected to the bottom of the base, and a turntable is coaxially fixedly connected to the rotating shaft. An air bladder is fixedly connected to the top of the turntable. The air bladder has several air ports, some of which are equipped with one-way inlet valves and others with one-way outlet valves. A spiral rising track is provided on the side wall of the vibratory plate. Several guiding mechanisms for straightening the core are provided in the rising track. The guiding mechanisms are uniformly fixedly connected to the inner wall of the rising track. An arched limiting block for vertically adjusting the position of the core is detachably connected in the track near the top of the vibratory plate. A vibration component for assisting the vibration of the turntable is provided between the turntable and the air bladder.

[0008] The technical principles of the above solution are as follows: The coil core in the hopper enters the base sidewall at a low height through the feeding track and then falls onto the turntable. An air bladder is fixed to the top of the turntable. The coil core first contacts the surface of the air bladder. Upon impact, the air bladder elastically deforms, absorbing the kinetic energy of the coil core's fall and preventing it from directly colliding with the rigid turntable. Gas inside the air bladder is then expelled from the air outlet, further dispersing the coil core and reducing collisions between them. Simultaneously, the air bladder surface has a certain degree of friction and flexibility, allowing the coil core to bounce slightly at its initial landing point before settling smoothly, reducing damage caused by mutual impact.

[0009] The airbag vibrates under the action of the vibration component, while the rotating shaft drives the turntable to rotate. Under the synchronous action of vibration force and centrifugal force, the core rolls towards the edge of the turntable and enters the rising track. Rolling along the track, the core is gradually adjusted and unified under the regularizing action of the guiding mechanism and the limiting block, and is then transported to the rear processing stage along the rising track.

[0010] The above approach has the following beneficial effects: 1. This solution effectively absorbs the impact kinetic energy when the core falls by setting up an airbag buffer, avoiding direct rigid collision between the core and the turntable. At the same time, air jets are used to further disperse the core, reducing collisions between cores, thereby reducing core deformation or damage and improving the product yield.

[0011] 2. This solution uses the vibration component in conjunction with the rotation of the turntable to make the core roll evenly towards the edge under the combined action of centrifugal force and vibration force. With the help of the guiding mechanism and limit block, the posture is gradually regulated, so as to achieve continuous and stable directional conveying, and improve the feeding efficiency and consistency.

[0012] 3. This solution adopts a spiral rising track and detachable limiting blocks, which can flexibly adjust the regular position according to different specifications of core, enhancing the versatility and adaptability of the device, while reducing problems such as material jamming and stacking, and improving production reliability.

[0013] Furthermore, the guiding mechanism includes elastic levers and telescopic guide rods, all of which are detachably connected to the inner wall of the track, and the elastic levers are hinged to the corresponding guide rods.

[0014] Beneficial effects: The elastic lever is hinged to the guide rod, which can adaptively adjust the lever force by its own elasticity and hinge swing when the core passes through, effectively correcting the skewed posture of the core without causing hard jamming; at the same time, the guide rod is detachable, which makes it easy to replace or adjust the position of the guide mechanism according to the core size, and can adapt to different specifications of cores.

[0015] Furthermore, a motor is fixedly connected to the bottom of the vibratory feeder, and the rotating shaft is coaxially and fixedly connected to the output end of the motor.

[0016] Beneficial effects: By directly driving the rotating shaft with a motor to rotate the turntable, a stable and controllable speed can be provided, making the centrifugal force on the core uniform and consistent. This is conducive to the core rolling smoothly towards the edge on the turntable and entering the rising track in an orderly manner, avoiding the speed fluctuation problem caused by manual or indirect drive.

[0017] Furthermore, the vibration assembly includes a pulse electromagnet and a magnetic block. The pulse electromagnet is fixed inside the turntable, the magnetic block is fixedly connected to the bottom of the airbag, and a leaf spring is fixedly connected to the bottom of the magnetic block. The bottom of the leaf spring is fixedly connected to the turntable.

[0018] Beneficial effects: The use of pulse electromagnets and magnetic blocks, with vibration transmitted through leaf springs, allows the airbag to rotate with the turntable and generate controllable micro-amplitude high-frequency vibrations. The leaf spring has a simple structure and sensitive response, which can effectively assist the core in overcoming static friction on the surface of the airbag and moving it to the edge, while avoiding rigid impacts and improving the smoothness of feeding.

[0019] Furthermore, the base is equipped with a control component for controlling the pulse electromagnet to generate periodic magnetic force. The control component includes a controller and a photoelectric sensor. The photoelectric sensor is located above the turntable, and the controller is fixedly connected inside the base. The photoelectric sensor and the pulse electromagnet are both electrically connected to the controller.

[0020] Beneficial effects: By using photoelectric sensors to detect the stacking density or conveying speed of the core on the turntable in real time, the controller automatically adjusts the working frequency of the pulse electromagnet accordingly, so that the vibration intensity is dynamically matched with the feeding requirements. This not only prevents the core from being too dense and causing blockage, but also avoids insufficient feeding due to weak vibration, thus achieving intelligent, energy-saving and stable feeding.

[0021] Furthermore, the inner wall of the vibratory feeder is provided with an elastic layer.

[0022] Beneficial effects: When the core moves towards the edge of the turntable and enters the rising track under the action of centrifugal force and vibration, it may touch the inner wall of the vibratory plate; the elastic layer can buffer the collision between the core and the inner wall, reduce scratches and chips on the edge or end face of the core, and at the same time absorb noise to a certain extent, thus improving the production environment.

[0023] Furthermore, an inclined plate is fixedly connected between the turntable and the rising track, and the side wall of the inclined plate is fixedly connected to the inner wall of the vibrating plate.

[0024] Beneficial effects: The inclined plate forms a smooth transition slope between the edge of the turntable and the entrance of the rising track, guiding the core to roll smoothly from the turntable surface into the track, avoiding material jumping and jamming caused by steps or gaps.

[0025] Furthermore, the surface of the inclined plate is provided with anti-slip texture.

[0026] Beneficial effects: The anti-slip texture increases the coefficient of friction between the core and the inclined plate, making the core's speed controllable and direction stable when sliding down the inclined plane. This prevents the core from sliding down quickly and disorderly or colliding with each other due to an overly smooth surface, and further ensures the consistency of the core's posture when entering the track.

[0027] Furthermore, the bottom of the limiting block is symmetrically and fixedly connected with retractable connecting rods, and the bottom ends of the connecting rods are all fixedly connected to the side wall of the rising track.

[0028] Beneficial effects: With symmetrically arranged telescopic connecting rods, operators can quickly adjust the height and angle of the limit block relative to the rising track to adapt to the vertical posture regularity requirements of capacitor cores of different heights or shapes; the telescopic structure is easy to adjust and reliable in positioning, and there is no need to replace the limit block as a whole, saving changeover time.

[0029] Furthermore, a transmission rail is detachably connected to the side of the ascending track near the top of the vibratory plate.

[0030] Beneficial effects: The detachable connection of the conveyor track makes it easy to flexibly extend or change the conveyor path according to the location of equipment in subsequent processes; at the same time, when it is necessary to clean the track, change product specifications, or maintain equipment, the conveyor track can be quickly removed, which improves the maintenance convenience of the device and the flexibility of the production line layout.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention.

Therefore, they should not be construed as limitations on the invention.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0036] The following detailed description illustrates the specific implementation method: Example 1:

[0037] As attached Figure 1 and Figure 3As shown: A capacitor core conveying and feeding device includes a hopper 1 and a vibrating plate 2. A base 3 is welded to the bottom of the vibrating plate 2. A feeding track 4 is connected to the bottom of the hopper 1. The other end of the feeding track 4 is connected to the base 3. Both ends of the feeding track 4 are fixedly connected to the side walls of the hopper 1 and the base 3, respectively. A rotating shaft 5 is rotatably connected to the bottom of the base 3. A turntable 6 is coaxially fixedly connected to the rotating shaft 5 (the turntable 6 is equipped with a screen for separating the core from impurities, and a cleaning groove is opened between the screen and the turntable 6). A motor 12 is fixedly connected to the bottom of the vibrating plate 2 (a support frame is installed at the bottom of the vibrating plate 2, and the motor 12 is located inside the support frame). The rotating shaft 5 is coaxially fixedly connected to the output shaft of the motor 12.

[0038] An airbag 7 is fixedly connected to the top of the turntable 6. The airbag 7 has several air ports, each with a one-way valve on its inner wall. Some air ports have inlet one-way valves, while others have outlet one-way valves. The outlet one-way valves allow gas inside the airbag 7 to diffuse outwards, while the inlet one-way valves allow gas to enter the airbag 7. (To further maintain the internal air pressure of the airbag 7, it can be connected to an air pump to replenish the internal air pressure.) A spiral ascending track 8 is provided on the inner wall of the vibrating plate 2, and an elastic layer 18 is provided on its inner wall. An inclined plate 19 is fixedly connected between the turntable 6 and the ascending track 8 (the angle between the inclined plate 19 and the turntable 6 is preferably 5 degrees; the inclined plate 19 acts as a buffer structure to reduce the resistance required during the upward movement of the winding core). The gravitational component is reduced, thereby reducing the resistance when the core rises. The inclined plate 19 is welded and fixed to the side wall of the vibratory plate 2. The bottom of the inclined plate 19 is connected to the turntable 6. The surface of the inclined plate 19 is provided with anti-slip texture 20. The rising track 8 is provided with several guide mechanisms for straightening the core. The guide mechanisms are uniformly fixed to the inner wall of the rising track 8. The rising track 8 near the top of the vibratory plate 2 is detachably connected with an arched limiting block 9 for vertically adjusting the position of the core. A vibration component for assisting the vibration of the turntable 6 is provided between the turntable 6 and the airbag 7. The design of the rising track 8 and the vibratory plate is based on the existing CNC vibratory plate (at the same time, small axial vibrators can be symmetrically installed on the outer wall of the vibratory plate 2 near the rising track 8 to help speed up the speed at which the core enters the rising track 8).

[0039] The specific implementation process is as follows: During feeding, the core is poured into hopper 1 (keeping it stationary in hopper 1). The core is then conveyed to base 3 via feeding track 4. The core first falls onto airbag 7, which acts as a buffer to prevent damage during the fall. Simultaneously, as the core falls onto airbag 7, gravity compresses it, causing gas to escape from the vents. This gas acts on the core, dispersing it in all directions. Because the inlet one-way valve controls air intake and the outlet one-way valve controls exhaust, the airbag 7 generates pulsed airflow during both intake and exhaust, further dispersing the core and effectively preventing collisions between cores, thus reducing core loss. Furthermore, the elasticity of the airbag 7 surface provides an upward force to the core, causing it to bounce upwards and disperse.

[0040] The motor 12 is started, which drives the rotating shaft 5 and the turntable 6 to rotate. During the rotation of the turntable 6, the core gains centrifugal force towards the surroundings and gradually moves towards the edge of the turntable 6. Under the vibration of the vibration component, the airbag 7 vibrates, further strengthening the upward elasticity of the core. Under the combined action of the basic elasticity of the airbag 7, the centrifugal force driven by the motor 12, and the vibration force of the vibration component, the core quickly and orderly passes through the inclined plate 19 (the inclined plate 19 connects the rising track 8 and the turntable 6) and enters the rising track 8 along the inclined plate 19. The anti-slip texture 20 on the surface of the inclined plate 19 increases the friction between the core and the inclined plate 19, preventing slippage and effectively improving the feeding efficiency. During the exhaust process of the airbag 7 and under the action of the basic elasticity of the airbag 7, metal particles, oxide layers, dust and other impurities attached to the surface of the core are blown away and shaken off simultaneously. Under the action of centrifugal force towards the surroundings, the impurities move towards the side wall of the base 3 and fall into the cleaning groove through the mesh of the screen.

[0041] As the core rises along the ascending track 8, the guiding mechanism will straighten any tilted cores to ensure that they continue to rise in the correct direction. When the core reaches the top of the ascending track 8, the arched limiting block 9 inside the ascending track 8 will adjust and screen the core vertically. The arched channel of the limiting block 9 only allows single-layer cores with the correct posture to pass through. Cores that are blocked will fall onto the airbag 7 and be reloaded.

[0042] In this design, the elastic layer 18 and the airbag 7 are used as a buffer structure. The airbag 7 can catch the cores falling from the feed track 4, and the elastic layer 18 can protect the cores that collide with the inner wall of the vibratory plate 2, thereby reducing the collision between the cores and the bottom wall of the vibratory plate 2. At the same time, the motor 12 drives the turntable 6 to rotate, and the cores receive centrifugal force that disperses in all directions, automatically moving towards the edge of the turntable 6. The vibration component between the turntable 6 and the airbag 7 applies continuous vibration to the airbag 7, which not only makes the cores disperse quickly in all directions and prevents damage to the cores, but also further improves the feeding rate. In addition, the elastic buffer and exhaust mechanism of the airbag 7 can reduce the collision between cores and remove impurities attached to the surface of the cores with the help of airflow, achieving protection and cleaning.

[0043] Example 2:

[0044] As attached Figure 4 and Figure 5 As shown, the difference from Embodiment 1 is that, in order to accommodate winding cores of different sizes, the guiding mechanism in this embodiment has been improved accordingly. Specifically, the guiding mechanism includes elastic levers 10 and telescopic guide rods 11 (the design of the guide rods 11 can refer to the existing LA-T8 mini electric telescopic rod). The guide rods 11 are all detachably connected to the inner wall of the rising track 8, and the elastic levers 10 are all hinged to the corresponding guide rods 11. The bottom of the limiting block 9 is symmetrically and fixedly connected to telescopic connecting rods 21 (the design of the connecting rods 21 can refer to the existing IP60 mini electric telescopic rod). The bottom end of the connecting rods 21 is fixedly connected to the side wall of the rising track 8. The side of the rising track 8 near the top of the vibratory feeder 2 is detachably connected to a transmission track 22.

[0045] The specific implementation process is as follows: Before feeding, the operator needs to adjust the length of the guide rod 11 and the height of the limit block 9 according to the size of the core. After the adjustment is completed, feeding begins.

[0046] During the conveying of the core along the ascending track 8, the elastic lever 10, with its elasticity and hinge structure, adaptively touches the side of the core as it passes by, straightening the core that is axially or radially skewed. Since the elastic lever 10 can swing around the hinge point, it will not jam the core and can straighten cores of different sizes.

[0047] After being horizontally aligned, the core roll moves along the rising track 8 to the top of the vibratory plate 2, and then enters the transmission track 22 after being screened by the limiting block 9, and is then transmitted to the subsequent processing structure.

[0048] In this design, the guiding mechanism features both telescopic and hinged adjustability, enabling it to adapt to various core specifications. It also assists in self-correction as the core rises. Simultaneously, the height of the limiting block 9 is telescopically adjustable, achieving precise vertical screening and improving the uniformity rate. Furthermore, the flexible adjusting block 10 reduces the risk of material jamming and damage.

[0049] Example 3:

[0050] As attached Figure 3 As shown, the difference from Embodiment 2 is that the vibration assembly includes a pulse electromagnet 13 and a magnetic block 14. The pulse electromagnet 13 is preferably an SDT-1912S series high-frequency pulse electromagnet 13. The pulse electromagnet 13 is fixed inside the turntable 6, and the magnetic block 14 is fixedly connected to the bottom of the airbag 7. A leaf spring 15 is fixedly connected to the bottom of the magnetic block 14, and the bottom of the leaf spring 15 is fixedly connected to the turntable 6. The base 3 is provided with a control assembly for controlling the pulse electromagnet 13 to generate periodic magnetic force. The control assembly includes a controller 16 and a photoelectric sensor 17. The photoelectric sensor 17 is located above the turntable 6, and the controller 16 is fixedly connected inside the base 3. The photoelectric sensor 17 and the pulse electromagnet 13 are both electrically connected to the controller 16. The photoelectric sensor 17 is preferably a BUP-30-P type photoelectric sensor 17, and the controller 16 is preferably a C10-1VF type frequency converter controller 16.

[0051] The specific implementation process is as follows: Start the motor 12, the rotating shaft 5 drives the turntable 6 to rotate, and at the same time, the controller 16 controls the pulse electromagnet 13 to generate periodic magnetic force. The pulse electromagnet 13 and the magnetic block 14 generate periodic magnetic coupling, thereby driving the leaf spring 15 to generate elastic deformation and reset, thereby driving the airbag 7 to generate high-frequency axial vibration.

[0052] During the conveying process, the photoelectric sensor 17 detects the stacking density and distribution of the core on the airbag 7 in real time. The photoelectric sensor 17 converts the detected light signal into an electrical signal and transmits it to the controller 16 in real time. When the photoelectric sensor 17 detects that the core stacking on the airbag 7 is too high (exceeding the set density threshold), the controller 16 increases the frequency of the pulse electromagnet 13 to enhance the vibration intensity of the airbag 7, while reducing the input frequency of the hopper 1 to accelerate the conveying speed of the core to the edge of the turntable 6 and the rising track 8.

[0053] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
