Description

Technical Field

[0001] This invention relates to the field of capacitor manufacturing technology, specifically a method for preventing the core leads from bending during capacitor manufacturing. Background Technology

[0002] Two conductors close to each other, with a non-conductive insulating medium in between, constitute a capacitor. When a voltage is applied between the two plates of the capacitor, the capacitor stores charge. The capacitance of a capacitor is numerically equal to the ratio of the charge on one conductive plate to the voltage between the two plates. Capacitors are common electronic components. A capacitor consists of a core, leads at one end of the core, a casing over the core, and rubber caps over the leads. The production of a capacitor requires multiple steps. For example, the Chinese authorized patent (capacitor production equipment) with announcement number CN116564723A includes a machine base, a conveying device, a clamping device, a straightening device, and a pin insertion device. The machine base is equipped with a feeder; the conveying device is located on the machine base; the clamping device is located on the machine base and is used to transfer elements from the feeder to the conveying device, separating the pins of the elements during the transfer process; the straightening device is located on the machine base and is used to straighten tilted elements on the conveying device; the pin insertion device is located on the machine base and is used to insert the pins of the elements conveyed by the conveying device into a cap. This capacitor production equipment uses automated means to insert the pins of the elements into the cap, exhibiting a high degree of automation and high work efficiency, making it highly worthy of promotion.

[0003] However, in the aforementioned existing technologies, the preceding processes in capacitor production include winding, impregnation, and assembly. When transitioning from one process to the next, the core package inevitably experiences contact and friction. This causes the core leads to bend easily under stress. Furthermore, when operators manually straighten the leads, weaker parts of the leads are prone to damage and defects. Such defective leads may appear broken but are not completely broken, and if they are released, they will exhibit poor performance, and in severe cases, they may even explode. Therefore, this does not meet the current requirements. In response, we have proposed a manufacturing method that prevents the core leads from bending during capacitor production. Summary of the Invention

[0004] The purpose of this invention is to provide a method for manufacturing capacitors without bending the core leads during production. This addresses the problem mentioned in the background art where, in the prior art, capacitor production processes include winding, impregnation, and assembly. When transitioning from one process to the next, the core package inevitably experiences contact and friction, making the core leads prone to bending under stress. Furthermore, when operators manually straighten the leads, weaker parts of the leads are easily damaged, resulting in defective leads that appear broken but are not. Once these defective leads are shipped out, they will exhibit poor characteristics, and in severe cases, may even explode.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a method for manufacturing capacitors without bending the core leads during production, comprising the following steps: Step 1: First, wind the cores together using a winding machine. When the capacitor winding machine starts working, the motor transmits power to the winding disc through the transmission device, causing it to rotate. At the same time, the control system controls the working status of the capacitor winding machine and monitors parameters such as the position and tension of the wire. Step 2: During the winding process, the wire to be wound is fixed on the nails on the reel, and the tension of the wire is adjusted. As the reel rotates, the wire will be wound on the reel. At the same time, the reel will adjust the winding speed according to the instructions of the control system. During this process, the capacitor winder will continuously detect the tension and position of the wire and adjust it according to different needs. When the wire is fully wound or reaches the set winding length, the capacitor winder will automatically stop working. Step 3: Then, heat treatment is performed on the capacitor. The capacitor is heated to a predetermined temperature to ensure uniform temperature throughout the capacitor and prevent thermal stress caused by temperature gradients. After that, the capacitor is kept warm and cooled at the predetermined temperature to improve its internal structure and achieve the required physical and chemical properties. Heat treatment also sterilizes and removes impurities from the capacitor. Step 4: Then, use an impregnation machine to perform an impregnation operation, immersing the capacitor's electrodes and surrounding areas in the electrolyte to ensure reliable contact between the electrodes and the electrolyte, enabling the electrodes to function normally. During the impregnation process, the electrolyte will form an aluminum oxide film on the aluminum foil surface, and at the same time, the electrolyte will form a relatively thick fixing layer on the electrode surface. Step 5: Finally, the assembly operation is performed. The assembly machine uses the electric field force between the two plates of the capacitor to fix one plate in place, while the other plate can reciprocate under the action of the electric field force. When the capacitor is connected to the power supply, the charge will accumulate between the two plates and form an electric field. When the capacitor is disconnected from the power supply, the charge will flow from one plate to the other plate, and the electric field will disappear. This charging and discharging process generates an electric field force, which causes one plate of the capacitor to reciprocate. The winding machine, impregnation machine, and assembly machine used in the above steps include: winding equipment, impregnation tank, holding basket, feeding mechanism, and heat treatment device. The winding equipment is provided with an operation panel on top, a support base is provided at the bottom of the operation panel, a material conveying frame is provided on one side of the upper surface of the support base, a control panel is provided on the front end of the operation panel, a first drive disk is provided below the control panel, a second drive disk is provided below the first drive disk, and a first placement rod is installed on both the first drive disk and the second drive disk.

[0007] Preferably, a movable groove is provided on one side of the limiting rod, a movable rod is installed inside the movable groove, and the movable rod is slidably connected to the inside of the movable groove. A limiting piece is provided on the front end face of the movable rod, a support bracket is installed below the limiting piece, and a second placement rod is installed on the front end face of the limiting piece.

[0008] Preferably, a cutting mechanism is provided on one side of the moving groove, a turntable is installed on the cutting mechanism, an adjusting rod is provided on the front end face of the turntable, and a cutting rod is installed at the bottom of the adjusting rod.

[0009] Preferably, a sealing cover is installed on the top of the impregnation tank, a motor is installed on the upper surface of the sealing cover, a sealing edge is installed on the lower surface of the sealing cover, and a limiting seat is provided at the bottom of the inside of the impregnation tank.

[0010] Preferably, a bottom plate is provided at the bottom of the interior of the holding basket, and an opening and closing plate is installed on the rear end face of the holding basket, the opening and closing plate being plugged into the holding basket.

[0011] Preferably, the top of the holding basket is provided with a support frame, the upper surface of the support frame is equipped with a driver, the bottom of the driver is provided with a lifting rod, and the lifting rod is fixedly connected to the upper surface of the base plate.

[0012] Preferably, the feeding mechanism has a base at its bottom, a support column on its upper surface, a feeding tray on its upper surface, a conveying channel inside the feeding tray, and a first discharge port on one side of the feeding tray.

[0013] Preferably, the rear end of the feeding mechanism is provided with a vibrating frame, and the front end of the vibrating frame is provided with a second discharge port.

[0014] Preferably, the front end of the heat treatment device is provided with a door, the rear end of the door is provided with a first heating wall, the interior of the heat treatment device is provided with a second heating wall, a rotating roller is installed between the second heating walls, a connecting frame is installed on the upper and lower end faces of both sides of the rotating roller, a tray is installed on the connecting frame, and the tray is rotatably connected to the connecting frame.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention utilizes a basket for holding core packages during the winding process. The core packages are then placed in the impregnation tank, and the wound core packages are conveyed directly to the basket via a conveyor frame for impregnation. This replaces the traditional core package turnover box, avoiding multiple transfers after the core packages are unloaded. This allows operators to easily verify the basket number before impregnating the cores. Furthermore, the basket is compatible with the impregnation tank and vibration frame, reducing friction and collisions between cores during unloading, preventing lead bending. This ensures that the cores in the capacitor production process do not undergo any intermediate transfers within the container, but directly move from one process to the next without direct human contact. This breaks away from the traditional production process of using mesh bags or baskets to hold cores for turnover before impregnation. After impregnation, the capacitor core can be directly placed on a vibratory conveyor for assembly and sealing via vibration. This eliminates the need for operators to rework the core leads during operation, reducing wasted time and significantly improving work efficiency. This method also reduces material blockages caused by bent core leads, further enhancing equipment production efficiency. It solves the problem in existing capacitor production processes, where the core bundle inevitably bumps and rubs against each other during transitions between processes. This causes the core leads to bend easily, and manual straightening can damage weak points, resulting in defective leads that appear broken but are actually broken. If these defective leads are discharged, they can cause poor performance and, in severe cases, even explosions.

[0016] 2. By installing an opening and closing plate on the end face of the basket, the opening and closing plate can be removed during assembly and conveying, aligning the opening with the second discharge port on the vibrating frame. This allows the material to enter the feeding tray through the second discharge port, where it is fed by the rotation of the feeding tray. Simultaneously, a motor is installed on the sealing cap at the top of the impregnation tank. When the basket is placed inside the tank, its bottom connects to the limiting seat inside the tank. The sealing cap on the impregnation tank seals the core package, meeting the stringent process standards required during production. This prevents the core from being directly exposed to air, causing electrolyte evaporation and absorption of moisture, which could affect product quality. When the sealing cap closes, its internal connecting bushing connects to the driver at the top of the basket, allowing the motor to drive the basket's rotation, ensuring uniform impregnation. The driver at the top of the basket also drives the lifting rod at the bottom, raising and lowering the bottom plate inside the basket for easy observation of the core package.

[0017] 3. By setting a limit rod on the winding equipment, the material being wound can be limited during the winding process to prevent deviation. At the same time, the cooperation of the support frame, limit plate and cutting mechanism on the operation panel can ensure the winding quality.

[0018] 4. By setting a rotating roller inside the heat treatment device, the rotating roller is driven by a motor, which in turn drives the connecting frame to rotate. However, the tray on the connecting frame is rotatably connected to the connecting frame. When the connecting frame rotates, the tray will always be in a stable upward state due to the weight of the basket on it. At the same time as the rotating roller rotates, the first heating wall and the second heating wall are used to heat treat it, ensuring the uniformity and quality of the heat treatment.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Please see Figure 1-6 The present invention provides an embodiment of a method for manufacturing capacitors with non-bending core leads during production, comprising the following steps: Step 1: First, wind the cores together using a winding machine. When the capacitor winding machine starts working, the motor transmits power to the winding disc through the transmission device, causing it to rotate. At the same time, the control system controls the working status of the capacitor winding machine and monitors parameters such as the position and tension of the wire. Step 2: During the winding process, the wire to be wound is fixed on the nails on the reel, and the tension of the wire is adjusted. As the reel rotates, the wire will be wound on the reel. At the same time, the reel will adjust the winding speed according to the instructions of the control system. During this process, the capacitor winder will continuously detect the tension and position of the wire and adjust it according to different needs. When the wire is fully wound or reaches the set winding length, the capacitor winder will automatically stop working. Step 3: Then, heat treatment is performed on the capacitor. The capacitor is heated to a predetermined temperature to ensure uniform temperature throughout the capacitor and prevent thermal stress caused by temperature gradients. After that, the capacitor is kept warm and cooled at the predetermined temperature to improve its internal structure and achieve the required physical and chemical properties. Heat treatment also sterilizes and removes impurities from the capacitor. Step 4: Then, use an impregnation machine to perform an impregnation operation, immersing the capacitor's electrodes and surrounding areas in the electrolyte to ensure reliable contact between the electrodes and the electrolyte, enabling the electrodes to function normally. During the impregnation process, the electrolyte will form an aluminum oxide film on the aluminum foil surface, and at the same time, the electrolyte will form a relatively thick fixing layer on the electrode surface. Step 5: Finally, the assembly operation is performed. The assembly machine uses the electric field force between the two plates of the capacitor to fix one plate in place, while the other plate can reciprocate under the action of the electric field force. When the capacitor is connected to the power supply, the charge will accumulate between the two plates and form an electric field. When the capacitor is disconnected from the power supply, the charge will flow from one plate to the other plate, and the electric field will disappear. This charging and discharging process generates an electric field force, which causes one plate of the capacitor to reciprocate. The winding machine, impregnation machine, and assembly machine used in the above steps include: a winding device 1, an impregnation tank 20, a holding basket 25, a feeding mechanism 37, and a heat treatment device 38. An operation panel 2 is mounted on the top of the winding device 1, a support base 3 is mounted at the bottom of the operation panel 2, a material conveyor 13 is mounted on one side of the upper surface of the support base 3, a control panel 4 is mounted on the front end of the operation panel 2, a first drive disc 5 is mounted below the control panel 4, and a second drive disc 6 is mounted below the first drive disc 5. The first drive disc 5 and the second drive disc 6... Each tray 6 is equipped with a first placement rod 7. During the winding process, a basket 25 is used to hold the core package, which is then placed into the impregnation tank 20. The wound core package is conveyed to the basket via the conveyor frame 13 for direct impregnation, replacing the traditional core package turnover box. This avoids multiple turnovers of the core package after it is unloaded, making it easier for operators to check the basket number before impregnating the core directly. Furthermore, the basket is matched with the impregnation tank 20 and the vibration frame 34, reducing friction and collision between cores during the unloading process, and preventing lead wire from being damaged. The bending process allows the capacitor cores to be transferred directly from one process to the next without any intermediate handling within the container. This eliminates the need for direct human contact with the core pack, breaking away from the traditional production process of using mesh bags or baskets to hold the cores for transfer and then impregnation. After impregnation, the cores can be placed directly on the vibrating frame 34 for assembly and sealing via vibration conveying. This eliminates the need for operators to rework the core leads during operation, reducing wasted time and significantly improving work efficiency. This method also reduces material blockage on the conveying machine caused by bent cores, further enhancing equipment production efficiency. It solves the problem in existing capacitor production processes, including winding, impregnation, and assembly, where the core pack inevitably bumps and rubs against each other during transfer. This causes the core leads to bend easily under stress, and manual straightening can damage weak points in the leads, resulting in defects. These defects, appearing broken but not actually broken, can lead to poor performance if they are discharged, and in severe cases, even explosions.

The sealing cover 21 on the impregnation tank 20 can seal the core package to meet the stringent process standards required during the production process, prevent the core from being directly exposed to the air, and prevent the electrolyte from evaporating and absorbing moisture from the air, which would affect the product quality.

Claims

1. A method for preventing the core leads from bending during capacitor manufacturing, including the following steps: Step 1: First, wind the cores together using a winding machine. When the capacitor winding machine starts working, the motor transmits power to the winding disc through the transmission device, causing it to rotate. At the same time, the control system controls the working status of the capacitor winding machine and monitors the position and tension of the wire. Step 2: During the winding process, the wire to be wound is fixed on the nails on the reel, and the tension of the wire is adjusted. As the reel rotates, the wire will be wound on the reel. At the same time, the reel will adjust the winding speed according to the instructions of the control system. During this process, the capacitor winder will continuously detect the tension and position of the wire and adjust it according to different needs. When the wire is fully wound or reaches the set winding length, the capacitor winder will automatically stop working. Step 3: Then, heat treatment is performed on the capacitor. The capacitor is heated to a predetermined temperature to ensure uniform temperature throughout the capacitor and prevent thermal stress caused by temperature gradients. After that, the capacitor is kept warm and cooled at the predetermined temperature to improve its internal structure and achieve the required physical and chemical properties. Heat treatment also sterilizes and removes impurities from the capacitor. Step 4: Then, use an impregnation machine to perform an impregnation operation, immersing the capacitor's electrodes and surrounding area in the electrolyte to form a reliable contact between the electrodes and the electrolyte, enabling the electrodes to work normally. During the impregnation process, the electrolyte will form an aluminum oxide film on the aluminum foil surface, and at the same time, the electrolyte will form a fixed layer on the electrode surface.
