Description

Technical Field

[0001] This application relates to the field of capacitor processing technology, and in particular to a capacitor core feeding mechanism. Background Technology

[0002] The capacitor manufacturing process involves multiple steps, including winding, gold spraying, heat setting, and assembly. The orderly arrangement of the capacitor cores at both ends is a crucial factor affecting production efficiency and product quality. Traditional production methods rely heavily on manual operation. Operators must manually separate stacked capacitor cores one by one, visually inspect the electrode positions and adjust their orientation, and then align the ends of the cores before neatly stacking them on a carrier or conveyor belt. This manual operation method has several drawbacks: First, a single operator can only process a few hundred capacitor cores per hour, resulting in low production efficiency and failing to meet the demands of modern large-scale production. Second, prolonged repetitive sorting and alignment operations can easily lead to visual fatigue and hand strain for operators, affecting operational accuracy. Third, manual operation can easily cause misalignment of capacitor cores, affecting the quality stability of subsequent gold spraying or welding processes, often requiring additional manual re-inspection, further increasing production costs. Furthermore, the consistency of manual operation is poor, making it difficult to ensure that the posture and position of each capacitor core meet process requirements, which creates difficulties for subsequent automated production lines. With the increasing automation in capacitor production, the reliance on manual material feeding has become a bottleneck restricting capacity expansion and product quality stability. Therefore, existing technologies urgently need improvement to address these issues. Utility Model Content To overcome the problems existing in related technologies, this application provides a capacitor core feeding mechanism that integrates a separation unit, electrode positioning and angle adjustment functions to achieve automated and orderly separation, precise attitude control and stable conveying of capacitor cores, effectively improving feeding efficiency and process adaptability.

In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0019] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0020] See Figure 1 and Figure 4 This application provides a capacitor core feeding mechanism, including a base 1 and a feeding assembly 2, a conveying assembly 3, a posture straightening assembly 4 and a discharging assembly 5 mounted on the base 1; The feeding assembly 2 is used to transport the capacitor core to be processed to the input end of the conveying assembly 3; The conveying assembly 3 is used to convey the capacitor core to the feed end of the discharge assembly 5; The attitude straightening component 4 is located above the conveying component 3 and includes a frame 41, a guide constraint structure 42, a drive unit 43, and a separation unit 44, a first clamping unit 45, and an angle adjustment unit 46 that are installed on the frame 41 and arranged sequentially along the conveying direction of the capacitor core. The guiding constraint structure 42 extends along the conveying direction and is suspended above the conveying assembly 3 via the frame 41, for defining the conveying trajectory of the capacitor core; The separation unit 44 is located above the guide constraint structure 42, and the driving unit 43 drives the separation unit 44 to rotate in order to separate the stacked capacitor cores. The first clamping unit 45 has two clamping surfaces, and electrodes for positioning the ends of the capacitor core are provided on the clamping surfaces; The angle adjustment unit 46 adjusts the angle of the capacitor core by rotating it; The discharge assembly 5 is used to maintain the orientation of the capacitor core and transport the capacitor core to the next process.

[0021] Specifically, the feeding assembly 2 can be connected to an external conveying device or manually loaded with capacitor cores. The feeding assembly 2 transports capacitor cores in batches to the conveying assembly 3. The feeding assembly 2 can use an inclined conveyor belt for continuous feeding, and vibration or gravity assistance is used to initially disperse the capacitor cores, preventing them from stacking and clogging. The end of the feeding assembly 2 connects to the input end of the conveying assembly 3. The conveying assembly 3 is a horizontal conveying structure and can be a belt conveyor. To improve the sliding friction on the capacitor cores, the surface of the belt conveyor can be covered with a rubber anti-slip layer to ensure that the capacitor cores can resist the reverse force of the separation unit 44. The posture straightening assembly 4 is located above the conveying assembly 3 and positions and adjusts the moving capacitor cores. Specifically, it achieves posture standardization through the coordinated operation of separation, clamping, detection, and rotation units, facilitating mechanized gold plating or welding of the capacitor cores.

[0022] In this embodiment, capacitor cores are conveyed from feeding assembly 2 to conveying assembly 3. During conveying, the conveying path of the capacitor cores is limited by the guiding constraint structure 42 to ensure that the capacitor cores can fall into the working positions of separation unit 44, first clamping unit 45, and angle adjustment unit 46. Separation unit 44 separates the stacked capacitor cores by a prying motion. The capacitor cores move in a single row along the conveying direction on conveying assembly 3, which facilitates the first clamping unit 45 to grasp the capacitor cores. The electrode structure set on the clamping surface is used to locate whether the end orientation of the capacitor cores is correct. Angle adjustment unit 46 rotates the capacitor cores to the target angle according to a preset program. Finally, the positioning plate 52 of the discharge assembly 5 holds the capacitor cores in position and conveys them to the gold spraying or welding station. Each component achieves continuous operation through timing control, completing the fully automated process of capacitor cores from disordered stacking to oriented arrangement.

[0023] In this embodiment, the electrodes on the clamping surface adopt a symmetrical double-contact layout. Each clamping surface embeds two circular conductive contacts with a diameter of 3mm. The spacing between the conductive contacts can be set to 5mm~10mm to adapt to the end dimensions of common capacitor cores. Simultaneously, the contact surface protrudes slightly beyond the clamping surface by 0.5mm to ensure full contact with the end electrodes of the capacitor core. Furthermore, to avoid scratching the capacitor core electrode layer, the contact edges can be rounded. The electrodes are made of brass substrate, and a 5μm thick gold layer can be plated on the surface to improve wear resistance and oxidation resistance, ensuring a contact resistance ≤50mΩ after long-term use. Simultaneously, the electrodes and clamping surfaces are insulated with PTFE gaskets to prevent current leakage or short circuits. In specific implementation, stepped holes are opened on the clamping surface. After the electrodes are pressed into the through holes with an interference fit, screws are used on the back to lock them to the clamping surface, ensuring that the electrodes are not loose. The first clamping unit 45 has a pre-reserved wire groove inside, and silver-plated copper wire is soldered to the back of the electrode. The wire is led through the groove to an aviation plug outside the first clamping unit 45 to achieve quick connection with the external detection circuit. The electrode is connected to the polarity detection module, which includes a 5V constant voltage source, a micro-current sensor, and a signal processing chip. When the clamping surface clamps the end of the capacitor core, the two electrodes contact the positive and negative terminals of the capacitor core, respectively. The detection module applies a weak current through the electrodes and determines the polarity based on the direction of the current. The electrode contact area can also integrate a pressure sensor. When the clamping force reaches a preset threshold, a positioning completion signal is triggered to ensure that the end of the capacitor core is completely in contact with the electrode, so as to avoid detection errors caused by poor contact. The motor detection result is transmitted to the angle adjustment unit 46 in real time through the signal processing chip. If the polarity is correct and the positioning is complete, the angle adjustment unit 46 maintains the current posture; if the polarity is incorrect, the angle adjustment unit 46 rotates the capacitor core by 90°.

[0024] It should be noted that the capacitor core involved in this application is a flat cylindrical shell with two ends and two sides. After the capacitor core is limited by the guide constraint structure 42, the two ends may correspond to the clamping surface, or the two sides may correspond to the clamping surface. At the same time, after being limited, the capacitor core is allowed to have a certain degree of inclination relative to the clamping surface on the conveying assembly 3 under the clamping of the first clamping unit 45.

[0025] In this embodiment, the present application achieves fully automated continuous feeding of capacitor cores, increasing processing efficiency to thousands of units per hour, completely eliminating the speed limitations of manual operation, and significantly improving product consistency in the gold plating or welding processes. The automated process reduces manual intervention, lowers labor intensity and quality re-inspection costs, and provides reliable technical support for the large-scale production of capacitors.

[0026] like Figure 2 and Figure 3Furthermore, the feeding assembly 2 includes a bracket 21, a conveyor belt 22, a storage bin 23, and a guide adjustment component 24. The conveyor belt 22 is obliquely mounted on the base 1 via the bracket 21. The storage bin 23 has an opening at the bottom, which is fastened to the conveyor belt 22. The storage bin 23 is provided with an inlet and an outlet. The outlet is connected to the guide adjustment component 24. The guide adjustment component 24 is used to adjust the landing position of the capacitor core in the conveying assembly 3.

[0027] The guide adjustment component 24 includes a housing 241, two guide plates 242, and a drive component 243. The housing 241 is mounted on the base 1, and its top side is connected to the discharge end of the conveyor belt 22. The two guide plates 242 are symmetrically arranged inside the housing 241 via a rotating shaft, respectively located on opposite inner sidewalls of the housing 241. The drive component 243 is fixed on the housing 241, and there are two drive components 243. The output end of the drive component 243 is connected to the guide plate 242 and is used to drive the guide plate 242 to rotate, thereby changing the tilt angle of the guide plate 242.

[0028] Specifically, the conveyor belt 22 is mounted at an angle on the base 1 via a bracket 21, with the angle adjustable from 30° to 45°. The bottom opening of the storage bin 23 is fastened to the surface of the conveyor belt 22. A feed inlet is located on the side of the storage bin 23 opposite to the conveyor belt 22. The operator feeds the capacitor cores into the storage bin 23 through the feed inlet. Under the action of the conveyor belt 22, the capacitor cores move along the conveying direction of the conveyor belt 22 to the discharge port. Due to the inclined conveyor belt 22, the capacitor cores are subjected to gravity during movement. Since the outer shell of the capacitor cores is made of metal, the friction between them is small. Under the action of gravity, the stacked capacitor cores can be separated. They then enter the housing 241 of the guide adjustment component 24. The guide plates 242 symmetrically arranged inside the housing 241 are adjusted at an angle via a drive component 243, forming a variable guide channel. As the capacitor cores slide along the surface of the guide plates 242, their landing position adjusts according to the angle of the guide plates 242. For example, when the guide plate 242 tilts inward, the landing point of the capacitor core shifts towards the center of the conveying assembly 3; when the guide plate 242 tilts outward, the landing point shifts to both sides. By dynamically adjusting the angle of the guide plate 242, the conveying requirements of capacitor cores of different specifications can be adapted to ensure that the landing point of the capacitor core can be aligned with the inlet of the guide constraint structure 42, thereby reducing the problem of blockage. In this embodiment, the housing 241 can be formed by welding metal sheets to create a box structure. The top opening of the housing 241 connects to the discharge end of the conveyor belt 22, and the bottom opening connects to the input end of the conveying assembly 3. The housing 241 restricts the movement path of the capacitor core. The guide plate 242 can be made of a smooth polyurethane board. The guide plate 242 is hinged to the side wall of the housing 241 via a rotating shaft. The two guide plates 242 are symmetrically inclined to form a V-shaped channel. The falling trajectory of the capacitor core can be changed by adjusting the tilt angle. The driving component 243 can be a push rod motor 463 or a stepper motor. When a stepper motor is selected, the output shaft of the stepper motor is connected to the rotating shaft through a gear transmission. The angle of the guide plate 242 can be adjusted by the forward and reverse rotation of the motor.

[0029] Furthermore, the discharge port is provided with a baffle plate 25, which has a plurality of elastic comb teeth extending toward the conveyor belt 22.

[0030] Specifically, the baffle plate 25 is installed on the discharge port of the storage bin 23. Elastic comb teeth are evenly distributed along the length of the baffle plate 25. The comb teeth are made of polyurethane, and the spacing between the teeth is slightly larger than the diameter of a single capacitor core, allowing for the separation of stacked capacitor cores and preventing jamming. When the conveyor belt 22 is running, if multiple capacitor cores stick together, the comb teeth are deformed under pressure and then reset, using elastic force to separate the stuck capacitor cores into a single layer. The distance between the baffle plate 25 and the conveyor belt 22 can be adjusted using bolt holes of different heights to accommodate the conveying needs of capacitor cores of different sizes.

[0031] Furthermore, the discharge port is also equipped with a through-beam switch, which is used to detect whether there is a capacitor core at the discharge port. If no capacitor core is detected for a long time, an alarm light will be used to remind the operator to add material.

[0032] like Figure 4 and Figure 5 As shown, the guide constraint structure 42 further includes a limiting channel and a width adjustment mechanism disposed at both ends of the limiting channel. The limiting channel includes a first limiting plate 421 and a second limiting plate 422 that are parallel to each other. The width adjustment mechanism includes a mounting bracket 423, a first screw 424, a second screw 425, a connecting block 426, a first slider 427 and a second slider 428. The mounting bracket 423 is mounted on the frame 41. The first screw 424 passes through the first end of the mounting bracket 423, and the second screw 425 passes through the second end of the mounting bracket 423. The first screw 424 and the second screw 425 are fixedly connected by a connecting block 426 and rotate synchronously. The first slider 427 is threadedly engaged with the first screw 424, and the second slider 428 is threadedly engaged with the second screw 425. The thread direction of the first screw 424 is opposite to the thread direction of the second screw 425, so that the first slider 427 and the second slider 428 move closer to or further away from the connecting block 426. The first limiting plate 421 is connected to the first slider 427, and the second limiting plate 422 is connected to the second slider 428. The end of the first screw 424 is also provided with a manual turntable 429.

[0033] Specifically, the limiting channel consists of a parallel first limiting plate 421 and a second limiting plate 422. The channel width is synchronously adjusted by width adjustment mechanisms at both ends. These mechanisms employ bidirectional screw drives to accommodate capacitor cores of different sizes. When the channel width needs adjustment, the operator rotates a manual turntable 429, causing the first screw 424 and the second screw 425 to rotate synchronously. Since the threads of the first screw 424 and the second screw 425 are opposite in direction, the first slider 427 and the second slider 428 move axially along the screw under the action of the threads, respectively moving the first limiting plate 421 and the second limiting plate 422 closer to or further away from the connecting block 426, thereby changing the distance between the two limiting plates. During this process, the width of the limiting channel is precisely adjusted to ensure that the capacitor core maintains a stable trajectory during transport, preventing the capacitor core from shifting or stacking due to an excessively wide channel.

[0034] Furthermore, the separation unit 44 includes a servo motor 441 and two parallel rollers 442. The servo motor 441 is fixed on the frame 41, and its rotating shaft is provided with a drive gear. The rollers 442 are provided with rotating shafts, and the two ends of the rotating shafts pass through the frame 41, with one end provided with a driven gear. The drive gear and the driven gear are connected by a transmission belt. The rotation direction of the servo motor 441 is opposite to the conveying direction of the conveying assembly 3. The outer periphery of the rollers 442 is provided with several outwardly extending elastic levers 443.

[0035] Specifically, two parallel rollers 442 are suspended above the limiting channel via a frame 41. 20 to 40 silicone elastic levers are evenly distributed around the outer circumference of the rollers 422. The length of the silicone elastic levers can be set to 20 mm to 30 mm. The servo motor 441 drives the rollers to rotate via gears and belts. The rotation speed of the rollers 442 can be set to 60-120 rpm, and the rotation direction is opposite to the movement direction of the conveying component 3. The silicone elastic levers are used to separate the stacked capacitor cores to ensure that each one passes through individually.

[0036] like Figure 6 As shown, the first clamping unit 45 further includes a dual-axis cylinder 451, a mounting base 452, and a clamp 453; the fixed end of the dual-axis cylinder 451 is fixed to the frame 41 by a crossbeam, and the output shaft of the dual-axis cylinder 451 is provided with the mounting base 452. The mounting base 452 is provided with a groove 4521 extending along the extension and retraction direction of the dual-axis cylinder 451 and an opening slot 4522 communicating with the groove 4521. One end of the clamp 453 is placed in the groove 4521, and a bolt is provided in the opening slot 4522. The bolt passes through the clamp 453 and is fastened by a nut. The clamp 453 has the clamping surface.

[0037] Specifically, one end of the clamp 453 is housed in the groove 4521 of the mounting base 452 and secured by bolts and nuts in the opening slot 4522; the other end of the clamp 453 is a clamping surface with electrodes for positioning the end of the capacitor core. These electrodes contact the end of the capacitor core, and the orientation of the capacitor core end is determined by detecting the conductivity of the electrodes, thus achieving automated positioning. The clamp 453 uses a smooth polyurethane plate to reduce wear on the capacitor core surface, while also possessing a certain degree of elasticity to accommodate minor differences in capacitor core dimensions. Its material is a conductive metal (such as copper alloy), and its smooth surface ensures good contact with the capacitor core's outer surface. The output shaft of the dual-axis cylinder 451 synchronously extends and retracts, causing the two mounting bases 452 to move towards each other, bringing the clamping surface of the clamp 453 into contact with the end electrodes of the capacitor core. The groove 4521 of the mounting base 452 constrains the clamp 453 to move along the cylinder extension direction. The bolt in the opening groove 4522 passes through the clamp 453 and is locked by the nut, allowing the operator to loosen the nut and adjust the installation angle of the clamp 453 in the groove 4521. When the capacitor core reaches the position of the first clamping unit 45 via the conveying assembly 3, the dual-axis cylinder 451 drives the clamp 453 to close. The clamping surface electrode clamps both ends or both sides of the capacitor core. The correct orientation of the capacitor core end is determined by the electrode conduction status. If the orientation of the capacitor core end is accurate, the angle adjustment unit 46 does not perform any action after the clamp releases the capacitor core. If the clamp 453 clamps both sides of the capacitor core, the electrode is not conductive. After the clamp 453 releases the capacitor, the angle adjustment unit 46 performs rotational correction.

[0038] Furthermore, the angle adjustment unit 46 includes a height adjustment component and a clamping component 460 with the same structure as the first clamping unit 45. The drive unit 43 is a rotary cylinder. The height adjustment component includes a lifting plate 461, a mounting plate 462, and a push rod motor 463. The lifting plate 461 is fixed to the frame 41 by a crossbeam. The mounting plate 462 is disposed on the lifting plate 461. The push rod motor 463 is fixed to the mounting plate 462, and the output shaft of the push rod motor 463 passes through the mounting plate 462 and is connected to the rotary cylinder. The fixed end of the rotary cylinder is provided with a slider. The lifting plate 461 is vertically provided with a guide rail, and the slider slides in cooperation with the guide rail.

[0039] Specifically, when the capacitor core reaches the angle adjustment unit 46 via the conveying assembly 3, the push rod motor 463 starts and drives the mounting plate 462 to move vertically along the lifting plate 461, causing the clamping member 460 to descend to the contact position with the capacitor core. The clamping member 460 is driven by the dual-axis cylinder 451 to close the clamping surface, fixing the electrodes at both ends of the capacitor core. Subsequently, the rotary cylinder drives the clamping member 460 to rotate around its axis, causing the capacitor core to rotate around its central axis to the target angle. During this process, the slider slides along the guide rail, constraining the lifting path of the rotary cylinder and preventing skew. After the angle adjustment is completed, the push rod motor 463 resets, the clamping member 460 releases the capacitor core, and the capacitor core continues to be conveyed to the discharge assembly 5.

[0040] like Figure 7 As shown, the capacitor core feeding mechanism further includes a second clamping unit, which has the same structure as the first clamping unit 45, and the angle adjustment unit 46 is located between the first clamping unit 45 and the second clamping unit. The discharge assembly 5 includes an adjusting plate 51 and two parallel positioning plates 52. The positioning plates 52 are mounted on the conveying assembly 3. Adjusting rods 53 are provided at both ends of the positioning plates 52. Fasteners 54 are provided at the ends of the adjusting rods 53 away from the positioning plates 52. The adjusting plate 51 has a slot 55 extending along its length. The fasteners 54 pass through the slots 55 and are fixed to the adjusting rods 53 and the adjusting plate 51 by locking components. The two positioning plates 52 of the discharge assembly 5 are connected to the adjusting plate 51 via the adjusting rods 53. After the operator loosens the locking components, the fasteners 54 can slide along the slots 55 to change the distance between the two positioning plates 52, matching the size of the capacitor core. After adjustment, the locking components are re-locked. The guide channel formed by the positioning plates 52 can accurately guide the capacitor core into the carrier of the next process.

[0041] like Figure 8 and Figure 9As shown, this application also proposes a gold spraying device 100, which includes a gold spraying mechanism, a housing 6, and the aforementioned capacitor core feeding mechanism. The housing 6 is covered on the base, and rotating doors are provided on both sides of the housing 6. The feeding operation and maintenance management of the capacitor core feeding mechanism can be realized through the doors. The discharge end of the discharge component 5 is connected to the receiving station of the gold spraying device 100. After the feeding station of the gold spraying device 100 transports the capacitor core to the gold spraying station, the gold spraying process can be performed.
