Description

Technical Field

[0001] This invention relates to the field of capacitor aging discharge technology, and in particular to a discharge device for secondary aging of aluminum electrolytic capacitors. Background Technology

[0002] In the secondary aging process of aluminum electrolytic capacitors, the design and operation of the discharge device are crucial. These devices are primarily used to accelerate capacitor aging by controlling the charging and discharging process, thereby assessing their long-term stability and reliability.

[0003] The prior art publication CN119291365B provides a fully automated capacitor aging test device. When multiple capacitors are continuously transported by a conveyor, the positive and negative leads of the multiple capacitors are sequentially passed through adjustment slots and guide slots to adjust the positive and negative leads of each capacitor to the same horizontal plane. After the multiple capacitors move to the second alignment mechanism, multiple guide tubes are moved close to the corresponding multiple capacitors so that the guide tubes are fitted onto the corresponding positive leads (if the positive leads are not aligned with the guide tubes, it is impossible to move the guide tubes to fit onto the positive leads). Through a pneumatic selection device, the capacitors with positive leads located in the guide tubes are rotated 180 degrees, while the capacitors with positive leads not in the guide tubes do not rotate. This achieves the adjustment of the positive or negative leads of multiple capacitors to the same side, which allows multiple capacitors to be quickly and accurately inserted into the capacitor test circuit board at the same time, thereby improving the test efficiency and the degree of automation.

[0004] Existing technology automatically inserts capacitor leads into the capacitor circuit test board. However, during use, capacitor leads may tilt or bend. Therefore, even if the capacitor leads have been adjusted to the same horizontal plane before testing, if the leads are bent or tilted, they may not be able to be accurately inserted into the slots of the test circuit board, resulting in test failure.

[0005] In summary, the existing technology lacks a technique for automatically correcting the bent leads of aluminum electrolytic capacitors. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of the prior art by providing a discharge device for the secondary aging of aluminum electrolytic capacitors.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a discharge device for secondary aging of aluminum electrolytic capacitors, comprising a discharge cabinet, a fixed base fixedly connected to the discharge cabinet, a fixed sleeve fixedly connected to the fixed base, a turntable rotatably connected through the fixed sleeve, two flipping frames rotatably connected to the turntable in a symmetrical structure, a capacitor positioning adjustment mechanism fixedly connected to the flipping frames, two push-pull mechanisms rotatably connected to the turntable in a symmetrical structure, and a capacitor pin correction mechanism provided on the push-pull mechanism.

[0008] Preferably, a discharge circuit board is fixedly connected to the mounting base.

[0009] Preferably, the outer wall of the fixing sleeve is provided with an annular stepped groove, and two arc-shaped racks are fixedly connected to one side of the top of the fixing sleeve.

[0010] Preferably, one end of the turntable passes through the fixed base and is fixedly connected to a motor, and the motor is fixedly connected to the fixed base.

[0011] Preferably, the tilting frame is rotatably connected to the turntable via a pin. An adjusting gear is fixedly connected to one end of the pin. An adjusting rack is meshed with one side of the adjusting gear. One end of the adjusting rack is slidably engaged with the inner wall of the turntable. A guide rod is fixedly connected to the bottom end of the adjusting rack. The other end of the guide rod is slidably engaged with the inner wall of the annular stepped groove.

[0012] Preferably, the capacitor positioning and adjustment mechanism includes an electric push rod 1, which is fixedly connected to the flipping frame. A motor 2 is fixedly connected to the output end of the electric push rod 1, and a placement sleeve is fixedly connected to the output end of the motor 2. An aluminum electrolytic capacitor is placed on the inner wall of the placement sleeve. Multiple electric push rods 2 are fixedly connected through the inner wall of the placement sleeve in a ring structure. A capacitor clamp is fixedly connected to the output end of the electric push rod 2, and the capacitor clamp abuts against the outer wall of the aluminum electrolytic capacitor.

[0013] Preferably, the push-pull mechanism includes a universal joint, one end of which extends through the top of the turntable and is fixedly connected to a hydraulic rod. The output end of the hydraulic rod is fixedly connected to a transmission wheel, which meshes with an arc-shaped rack for transmission. The other end of the universal joint is fixedly connected to a reciprocating screw, and the other end of the reciprocating screw is rotatably connected to a fixed frame. One end of the fixed frame is fixedly connected to the top of the turntable.

[0014] Preferably, the capacitor pin correction mechanism includes a slide block, which is slidably coupled to a reciprocating lead screw. An electric actuator three is fixedly connected to the top of the slide block, and a correction frame is fixedly connected to the output end of the electric actuator three. The other end of the correction frame has an E-shaped opening, and the two sides of the opening of the correction frame have an flared and inclined structure. Two pin clamps are slidably coupled to the inner wall of the correction frame in a symmetrical structure. A spring is fixedly connected between one end of the pin clamp and the correction frame.

[0015] Preferably, the pin clamp has two L-shaped rods symmetrically arranged at one end of the opening of the correction frame. A correction block is fixedly connected to the top of the L-shaped rod. An inclined groove is formed on the inner wall of the opening of the correction frame at the bottom of the L-shaped rod. The inner wall of the inclined groove is slidably engaged with the bottom of the L-shaped rod. A contact rod is fixedly connected to the end of the pin clamp near the spring. A contact plate is fixedly connected to the slide. Inclined surfaces are formed on both sides of the bottom of the contact plate. The bottom of the contact rod is slidably contacted with the side wall and the inclined surfaces of the contact plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By setting up a capacitor pin correction mechanism, before inserting the aluminum electrolytic capacitor pins into the discharge circuit board for discharge, the capacitor pin correction mechanism can automatically correct the pins when they are tilted or bent. The corrected pins can accurately align with the holes on the circuit board, reducing assembly errors caused by pin tilting or bending, and improving insertion accuracy. The capacitor pin correction mechanism can effectively improve production efficiency and capacitor performance, ensuring that the capacitor works stably and reliably in the discharge device during secondary aging.

[0018] 2. By setting up a push-pull mechanism, while the turntable rotates and drives the aluminum electrolytic capacitor to the discharge circuit board, the push-pull mechanism can automatically drive the capacitor pin correction mechanism to push out and retract, thereby correcting the pins. By driving the capacitor pin correction mechanism through the push-pull mechanism, the aluminum electrolytic capacitor is automatically corrected during the process of the turntable moving to the discharge circuit board, and the pins are inserted straight. This not only improves automation and efficiency, but also enhances the accuracy and reliability of the secondary aging test, while reducing the risk of damage, rework rate and production cost.

[0019] 3. By setting up a flipping frame, while the turntable rotates and drives the aluminum electrolytic capacitor to discharge, it can automatically flip up and down, and the pins are automatically corrected and accurately aligned with the discharge circuit board. This not only improves the degree of automation and discharge accuracy, but also improves the consistency of secondary aging discharge, reduces the risk of equipment and capacitor damage, saves time and costs, and enhances the overall reliability of the system.

Detailed Implementation

[0030] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0031] like Figures 1-8 The discharge device shown includes a discharge cabinet 1, a fixed base 2 fixedly connected inside the discharge cabinet 1, a fixed sleeve 3 fixedly connected to the fixed base 2, a turntable 4 rotatably connected through the fixed sleeve 3, two flipping frames 5 rotatably connected to the turntable 4 in a symmetrical structure, a capacitor positioning adjustment mechanism 6 fixedly connected to the flipping frame 5, and two push-pull mechanisms 7 rotatably connected to the turntable 4 in a symmetrical structure, with a capacitor pin correction mechanism 8 provided on the push-pull mechanism 7.

[0032] like Figure 3 As shown, a discharge circuit board 201 is fixedly connected to the mounting base 2.

[0033] The discharge circuit board 201 is made of flame-retardant epoxy fiberglass board, and its withstand voltage is adapted to the discharge voltage of aluminum electrolytic capacitors after secondary aging. The board is equipped with discharge sockets that are precisely corresponding to the capacitor pins.

[0034] like Figure 4 As shown, the outer wall of the fixed sleeve 3 has an annular stepped groove 301, and two arc-shaped racks 302 are fixedly connected to one side of the top of the fixed sleeve 3. The groove wall of the annular stepped groove 301 is polished and divided into two steps, a high position and a low position, to precisely control the flipping angle of the flipping frame 5 from 0° to 180°, ensuring that the leads of the capacitor are facing the discharge circuit board 201 after flipping. The arc-shaped racks 302 are made of high-precision quenched steel, with regular tooth shape, wear resistance and durability, and high meshing transmission accuracy. Its curvature is perfectly matched with the rotation trajectory of the turntable 4 and the movement stroke of the push-pull mechanism 7, realizing the automatic triggering of the push-pull mechanism 7 during capacitor transfer without the need for additional power drive, reducing energy consumption and structural complexity. The annular stepped groove 301 and the arc-shaped racks 302 are set coaxially to ensure that the flipping and correction actions are synchronized and coordinated without interference.

[0035] like Figure 3 As shown, one end of the turntable 4 passes through the fixed base 2 and is fixedly connected to a motor 401, which is fixedly connected to the fixed base 2.

[0036] The 401 motor adopts a servo geared motor with adjustable speed, precise positioning, and fast start / stop response. It can accurately control the rotation angle and dwell time of turntable 4, and realize precise cycle control of dual-station cyclic operation.

[0037] like Figure 5As shown, the tilting frame 5 is rotatably connected to the turntable 4 via a pin. An adjusting gear 501 is fixedly connected to one end of the pin. An adjusting rack 502 is meshed and driven on one side of the adjusting gear 501. One end of the adjusting rack 502 is slidably engaged with the inner wall of the turntable 4. A guide rod 503 is fixedly connected to the bottom end of the adjusting rack 502. The other end of the guide rod 503 is slidably engaged with the inner wall of the annular stepped groove 301.

[0038] The flipping frame 5 is made of lightweight, high-strength aluminum alloy, which is lightweight and has a strong load-bearing capacity, and can stably support the capacitor positioning and adjustment mechanism 6 and the aluminum electrolytic capacitor.

[0039] like Figure 6 As shown, the capacitor positioning and adjustment mechanism 6 includes an electric push rod 601, which is fixedly connected to the flipping frame 5. A motor 602 is fixedly connected to the output end of the electric push rod 601, and a placement sleeve 603 is fixedly connected to the output end of the motor 602. An aluminum electrolytic capacitor is placed on the inner wall of the placement sleeve 603. Multiple electric push rods 604 are fixedly connected to the inner wall of the placement sleeve 603 in a ring structure. A capacitor clamp 605 is fixedly connected to the output end of the electric push rod 604, and the capacitor clamp 605 abuts against the outer wall of the aluminum electrolytic capacitor.

[0040] Electric actuator 601 is a high-precision miniature electric actuator with adjustable stroke, which can drive motor 602 and placement sleeve 603 to move up and down, achieving precise docking of capacitor pins with the sockets of discharge circuit board 201. Motor 602 is a miniature stepper motor that can drive placement sleeve 603 to rotate. In conjunction with the photoelectric sensor at the top of the fixing bracket 704, it automatically detects the angle of capacitor pins and adjusts the pins to a symmetrical position to prepare for subsequent correction. Placement sleeve 603 is made of insulating and wear-resistant plastic material, and the inner wall curvature is adapted to the outer wall of aluminum electrolytic capacitor to avoid scratching the capacitor shell. Electric actuator 604 is evenly distributed in a ring and synchronously extends and retracts to drive capacitor clamp 605 to clamp the capacitor. The clamping force is uniform and prevents the capacitor from rotating or shifting. Silicone anti-slip pads are added to the inner side of capacitor clamp 605 to ensure firm clamping without damaging the outer wall of the capacitor.

[0041] like Figure 7As shown, the push-pull mechanism 7 includes a universal joint 701. One end of the universal joint 701 extends through the top of the turntable 4 and is fixedly connected to a hydraulic rod. The output end of the hydraulic rod is fixedly connected to a transmission wheel 702, which meshes with the arc-shaped rack 302 for transmission. The other end of the universal joint 701 is fixedly connected to a reciprocating screw 703, and the other end of the reciprocating screw 703 is rotatably connected to a fixing frame 704. One end of the fixing frame 704 is fixedly connected to the top of the turntable 4. A photoelectric sensor is installed at the top of the fixing frame 704. After the aluminum electrolytic capacitor is clamped and fixed, the sensor controls the rotation of the placement sleeve 603 based on the detection result, so that the two pins are at a symmetrical angle, facilitating the insertion of the straightening frame 803.

[0042] Building upon this foundation, an intelligent vision sensor is also installed on one side of the 704 mounting bracket, forming a multi-dimensional intelligent detection closed loop. The intelligent vision sensor employs a high-definition industrial macro probe, coupled with an image recognition algorithm, to collect real-time data on capacitor pin posture, bending angle, and spacing. It converts analog signals into digital signals and transmits them to the equipment's main control system, accurately identifying abnormalities such as pin misalignment, deformation, and missing pins. Through the collaborative work of the intelligent sensor and photoelectric sensor, fully intelligent control of capacitor posture detection and abnormality warning is achieved, further enhancing the automation accuracy, fault tolerance, and operational safety of the device.

[0043] The hydraulic rod enables the transmission wheel 702 to engage with the arc-shaped rack 302 when pin alignment is required, and to disengage the transmission wheel 702 from the arc-shaped rack 302 when alignment is not required. The photoelectric sensor adopts an infrared through-beam type, which has high detection accuracy and can quickly identify the pin position and feed back the signal to the motor 602 to realize automatic pin angle calibration. No manual intervention is required throughout the process, thus improving the level of automation.

[0044] like Figure 8 , Figure 9 As shown, the capacitor pin correction mechanism 8 includes a slide block 801, which is slidably engaged with a reciprocating lead screw 703. An electric push rod 802 is fixedly connected to the top of the slide block 801, and a correction frame 803 is fixedly connected to the output end of the electric push rod 802. The other end of the correction frame 803 has an E-shaped opening, and the two sides of the opening of the correction frame 803 have an flared and inclined structure. The inner wall of the correction frame 803 has two pin clamps 804 that are symmetrically engaged and slidably engaged. A spring 805 is fixedly connected between one end of the pin clamp 804 and the correction frame 803.

[0045] The electric actuator 802 uses a miniature servo actuator to precisely adjust the height of the straightening frame 803, adapting to the pin length of aluminum electrolytic capacitors. The straightening frame 803 is made of insulated hard plastic, and its E-shaped opening can simultaneously wrap two capacitor pins. The flared and tilted structure acts as a guide, facilitating the smooth entry of skewed pins into the straightening area and preventing jamming. The inner side of the pin clamp 804 is smoothed to prevent scratching the pin plating. The spring 805 is a stainless steel return spring with stable elasticity. In its natural state, it pushes the pin clamp 804 open, reserving space for the pins to enter.

[0046] Two L-shaped rods 806 are symmetrically arranged and slidably fitted at one end of the lead clamp 804 at the opening of the straightening frame 803. A straightening block 807 is fixedly connected to the top of each L-shaped rod 806. A sloping groove 808 is formed on the inner wall of the opening of the straightening frame 803 at the bottom of the L-shaped rod 806, and the inner wall of the sloping groove 808 slidably engages with the bottom of the L-shaped rod 806. A contact rod 809 is fixedly connected to one end of the lead clamp 804 near the spring 805. A contact plate 810 is fixedly connected to the slide block 801. Sloping surfaces 811 are formed on both sides of the bottom of the contact plate 810. The bottom of the contact rod 809 slidably contacts the side wall of the contact plate 810 and the sloping surfaces 811. The sloping surfaces 811 allow the lead clamp 804 connected to the contact rod 809 to move outward and engage with the inner wall of the opening of the straightening frame 803, thus achieving left and right straightening of the capacitor leads. The skewed slot 808 enables the two straightening blocks 807 to move closer to each other while the pin clamp 804 moves, thus straightening the pins back and forth.

[0047] The L-shaped rod 806 is made of wear-resistant metal and slides smoothly with the pin clamp 804. The straightening block 807 is made of soft insulating rubber, which fits the pin surface and leaves no scratches during straightening. The inclined groove 808 is precision milled with a precise tilt angle. When the pin clamp 804 moves, the bottom end of the L-shaped rod 806 slides along the inclined groove 808, causing the two straightening blocks 807 to move inward synchronously, completing the bending and straightening of the pin in the front and back directions. When the slide block 801 moves, the contact rod 809 slides along the inclined surface 811, pushing the pin clamp 804 to move, and working with the straightening frame 803 to complete the skew correction of the pin in the left and right directions, ensuring that the pin is completely straight.

[0048] By setting up a capacitor pin correction mechanism 8, before inserting the aluminum electrolytic capacitor pins into the discharge circuit board 201 for discharge, the capacitor pin correction mechanism 8 can automatically correct the pins when they are tilted or bent. The corrected pins can accurately align with the holes on the circuit board, reducing assembly errors caused by pin tilting or bending, and improving insertion accuracy. The capacitor pin correction mechanism 8 can effectively improve production efficiency and capacitor performance, ensuring that the capacitor works stably and reliably in the discharge device during secondary aging.

[0049] Working principle: After the device is powered on, motor 401 locks turntable 4, and the dual-station tilting frame 5 is in the loading / unloading station and the discharge station respectively. The operator puts the aluminum electrolytic capacitor after secondary aging into the placement sleeve 603 in the loading station. The electric push rod 604 extends synchronously, driving the capacitor clamp 605 to retract towards the center and evenly clamp the outer wall of the capacitor. The infrared photoelectric sensor at the top of the fixed frame 704 immediately detects the pin position and feeds the signal back to motor 602. Motor 602 drives the placement sleeve 603 to rotate slightly, adjusting the capacitor pin to a symmetrical angle to prepare for subsequent pin correction. When a bend in the pin is detected, the hydraulic rod drives the transmission wheel 702 to move to a position that can mesh with the arc-shaped rack 302.

[0050] After the positioning calibration is completed, motor 401 starts and drives turntable 4 to rotate at a constant speed, transferring the capacitor from the loading station to the discharge station. At the same time, the capacitor that has completed the discharge at the discharge station is transferred to the loading and unloading station. At this time, the guide slide 503 is located at the horizontal position at the bottom of the annular stepped groove 301, so that the capacitor keeps the pins facing upward.

[0051] Then, while the turntable 4 is transferring the capacitor, the transmission wheel 702 rotates along the arc-shaped rack 302 with the turntable 4, driving the reciprocating screw 703 to rotate through the universal joint 701, thereby driving the slide 801 to move smoothly towards the capacitor. When the open end of the straightening frame 803 is inserted into the two pins, the transmission wheel 702 disengages from the arc-shaped rack 302, and the electric push rod 802 drives the straightening frame 803 to move upward. At this time, the bottom end of the contact rod 809 slides along the inclined surface 811 of the contact plate 810, pushing the pin clamp 804 to move and cooperate with the inner wall on one side of the open end of the straightening frame 803 to clamp and straighten the pins from left and right. At the same time, when the pin clamp 804 moves, it moves along the inclined groove 808.

[0052] Under the action of the two straightening blocks 807, they will move inward synchronously to straighten the pins. Then, when the electric push rod 802 continues to push upward, it can straighten the bent pins.

[0053] Then the transmission wheel 702 will mesh with another arc-shaped rack 302, thereby continuing to drive the reciprocating screw 703 to rotate, thereby driving the capacitor pin correction mechanism 8 to reset. At the same time, the electric push rod 802 drives the correction frame 803 to move down and reset.

[0054] When the capacitor is about to be transferred to the discharge station, the guide slide 503 will move from the horizontal position at the bottom of the annular stepped groove 301 to the horizontal position of the annular stepped groove 301. At this time, it will drive the adjusting rack 502 to slide upward. The adjusting rack 502 and the adjusting gear 501 mesh and drive the drive pin to drive the flipping frame 5 to slowly flip downward by 180°, so that the capacitor changes from a vertical loading posture to a downward discharge posture, with the pins precisely aligned with the discharge circuit board 201. The motor 401 stops rotating and locks the turntable 4. The electric push rod 601 extends and drives the capacitor downward. The straightened pins are precisely inserted into the discharge socket of the discharge circuit board 201. The discharge circuit board 201 immediately starts the discharge program and quickly releases the residual charge of the capacitor through the current limiting resistor. After the discharge is completed, the electric push rod 601 retracts, driving the capacitor to detach from the discharge circuit board 201.
