Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of conveying devices, in particular to a conveying device and method for packaging aluminum electrolytic capacitors. BACKGROUND

[0002] The packaging device is mainly composed of a rotary locking unit, a hot melt sealing module and a pressure control system. The core principle is to realize the airtight sealing of the capacitor by mechanical force and heat force. The rotary locking device (feed tray) adopts V-shaped contraction groove matched with spring chuck. When the adjusting cylinder pushes the connecting rod, the spring chuck shrinks radially in the V-shaped groove, accurately clamping the aluminum shell. Then, the sealing cylinder drives the sealing pressure wheel to apply vertical pressure to the aluminum shell opening, while the hot melt module (such as the three-way forming briquette as described in the patent) melts the aluminum shell edge and rubber plug by heat, forming a permanent seal. This process needs to strictly control the pressure and temperature to avoid overpressure leading to aluminum shell deformation or insufficient sealing causing electrolyte leakage.

[0003] The conveying device relies on the cooperative operation of the ring-shaped step conveyor belt and the multi-channel feeding system to realize efficient continuous production. The ring-shaped step conveyor belt is driven by a motor-driven rotating shaft, which drives the rotating sleeve to rotate periodically through the transmission belt. The step distance is accurately matched with the distance between the stations. The feeding end adopts multiple parallel feeding pipes, and the pusher rod cylinder pushes the pusher column to synchronously push the capacitor inner core and cover into multiple packaging shell covers. The conveying support sequentially receives the materials and moves them to the packaging station during the stepping.

[0004] During the feeding process of the aluminum electrolytic capacitor packaging conveying device, the unsealed capacitors are usually moved to the top of the feeding tray and then released, so that the capacitors rely on free fall to fall into the inside of the clamp. The collision caused by free fall can easily cause deformation of the aluminum shell or damage to the internal structure, especially when the capacitor hits the inner wall of the clamp non-perpendicularly, the aluminum shell may have concave, indentation or notch burr, affecting the subsequent sealing tightness. Secondly, the positioning deviation during the falling process may cause oblique placement or jamming, causing the winding core package (including positive and negative electrode foils and electrolytic paper) to shift or the guide pin to bend, which not only reduces the packaging accuracy, but also may cause unstable capacity or even no capacity failure due to poor riveting, core extraction, etc. In addition, repeated impact will exacerbate the wear of the inner wall of the clamp, shorten the service life of the equipment, and increase the surface residual debris or scratches of the aluminum shell, weaken the pressure resistance and scratch resistance of the coated aluminum shell; finally, this method has a high risk of damaging precision parts such as rubber plugs, which may damage the integrity of the sealing structure and increase the probability of electrolyte leakage, ultimately leading to excessive leakage current or life attenuation of the product.

[0023] In the embodiment, the accelerator 3 can also be provided as a speed reducer, the speed reducer is reversely installed in connection with the accelerator 3, the feeding tray 2 drives the driving wheel 51 to rotate through the meshing effect, the driving wheel 51 drives the driven wheel 53 to rotate through the accelerator 3, the accelerator 3 realizes the conversion of 60 degrees of rotation of the driving wheel 51 into 180 degrees of rotation of the driven wheel 53 through the gear combination, the driven wheel 53 drives the transmission wheel 54 to rotate synchronously through the toothed belt 52, the transmission wheel 54 drives the rotating plate 8 to rotate synchronously, when the feeding tray 2 rotates to the top and the clamping shaft line of one of the clamps is consistent with the shaft line of the supporting plate 101, the rotating plate 8 releases the support of the hollow ring 91, and further releases the restriction of the damping spring 6. The buffer part 9 moves to the direction close to the feeding tray 2 under the action of its own gravity, the damping spring 6 releases the elastic force to push the hollow ring 91 to move along the outer side of the connecting rod 61, the side gear 93 drives the side rod 92 to rotate positively through the meshing effect with the toothed plate 94, and the side rod 92 drives the fixed rod 95 to move synchronously.

[0024] Specifically, the buffer part 9 also includes a pulley 96, which is rotatably connected to the inner side of the other end of the fixed rod 95. An elastic element 1 is fixed to the inner side of the side rod 92, and the other end of the elastic element 1 is fixedly connected to the fixed rod 95. The toothed plate 94 meshes with the side gear 93. The support member 10 includes a support plate 101 and a second base plate 102. The support plate 101 is fixed to the top of the toothed plate 94, and the second base plate 102 is slidably engaged with the inner side of the support plate 101. An elastic element 2 is fixed to one end of the second base plate 102, and the other end of the elastic element 2 is fixed to the inner side of the support plate 101.

[0025] In this embodiment, the hollow ring 91 drives the locking post 97 and the wedge plate 98 to move towards the side closer to the feeding tray 2. When the hollow ring 91 contacts the first base plate 7, the locking post 97 and the wedge plate 98 are completely removed from the inside of the support plate 101, thereby releasing the restriction on the feeding track 14 and the second base plate 102. Under the action of the elastic element 2, the second base plate 102 moves towards the axis of the support plate 101. Then, the feeding track 14 transports the aluminum electrolytic capacitor to the top of the support plate 101. The outer side of the aluminum electrolytic capacitor contacts the inner side of the corner bracket 62 to ensure the aluminum electrolytic capacitor... The axis of the capacitor is aligned with the axis of the support plate 101 and the hollow ring 91. Then the feed plate 2 continues to rotate. During the rotation of the rotating plate 8 by 90 degrees, the hollow ring 91 does not move. During the rotation of the rotating plate 8 from 90 degrees to 180 degrees, the rotating plate 8 squeezes the hollow ring 91 and moves it along the outside of the connecting rod 61 towards the side closer to the corner bracket 62. The hollow ring 91 squeezes the damping spring 6 to restore it to its initial state. The side gear 93 drives the side rod 92 to reverse through the meshing action with the toothed plate 94. The side rod 92 drives the fixed rod 95 to move accordingly, and finally restores the initial state.

[0026] Specifically, the encapsulation assembly includes a base 11, which is fixedly connected to the bottom of the feeding tray 2. An accelerator 3 is fixed to the top of the base 11. A waist-binding machine 12 and a sealing machine 13 are fixed to the top of the base 11. The sealing machine 13 is located on one side of the waist-binding machine 12. A feeding track 14 and a discharging track 15 are fixed to the top of the base 11. The feeding track 14 is located on one side of the waist-binding machine 12, and the discharging track 15 is located on one side of the sealing machine 13. A support plate 101 is fixedly connected to the output end of the feeding track 14.

[0027] In this embodiment, before using this device, the aluminum electrolytic capacitor needs to be assembled first. The worker packs the core containing the electrolyte into the aluminum shell, and the rubber stopper (including electrode leads) is pre-installed at the port of the aluminum shell. Epoxy resin is injected into the encapsulation part of the capacitor (the gap between the rubber stopper and the aluminum shell) to enhance the sealing of the product, thereby extending the evaporation cycle of the capacitor electrolyte and thus extending the product life. Then, the base is fixed to the bottom of the aluminum shell by threads or buckles. Finally, the aluminum electrolytic capacitor that has completed the initial assembly will be fed to the top of the feeding track 14. After the aluminum electrolytic capacitor is completely moved into the inner side of the clamp at the top of the feeding tray 2, the feeding tray 2 continues to rotate to transport the aluminum electrolytic capacitor to the inner side of the waisting machine 12. The waisting machine 12 forms an annular pressure groove on the surface of the aluminum electrolytic capacitor shell through lateral pressure, causing the shell to shrink inward and fit tightly against the cell, forming a physical snap-fit ​​structure, thereby restricting the displacement of the cell. This is existing technology and will not be elaborated further. The feeding tray 2 continues to rotate to transport the aluminum electrolytic capacitor to the inner side of the sealing machine 13. The sealing machine 13 uses ceramic sealing needles to roll and press the edge of the aluminum shell opening under high-speed rotation, and rotates and presses the opening of the aluminum electrolytic capacitor shell after waisting to achieve permanent sealing.

[0028] Specifically, a discharge component 4 is fixedly connected to the input end of the discharge track 15; the discharge component 4 includes a bracket 41 fixed to the input end of the discharge track 15, a horizontal plate 42 is slidably engaged on the inner side of the bracket 41, a cylinder 43 is fixed to the top of the horizontal plate 42, a telescopic rod 44 is fixed to the side of the bracket 41 away from the feed track 14, the output end of the telescopic rod 44 is fixedly connected to the horizontal plate 42, a C plate 45 is fixed to the output end of the cylinder 43, a clamping plate 46 is slidably connected to the inner side of the C plate 45, a limit plate 47 is fixed to the side of the two clamping plates 46 away from each other, an elastic element three is fixed to the side of each limit plate 47 near the clamping plate 46, the other end of the elastic element three is fixedly connected to the C plate 45, and two symmetrically arranged separation plates 48 are fixed to the inner walls of both sides of the C plate 45.

[0029] In this embodiment, the feeding tray 2 continues to rotate, conveying the aluminum electrolytic capacitor to the bottom of the discharge component 4. After processing, the aluminum electrolytic capacitor is moved into the inner side of the two clamping plates 46. Under the action of the elastic element 3, the two clamping plates 46 clamp the aluminum electrolytic capacitor. The control cylinder 43 retracts, and the cylinder 43 drives the clamping plates 46 to move closer to the top of the support 41 through the C plate 45. When the top of the C plate 45 is on the same horizontal plane as the bottom of the separation plate 48, the cylinder 43 is closed. The operator controls the telescopic rod 44 to retract, and the telescopic rod 44 drives the horizontal plate 42 to move. When the separation plate 48 moves to the side where the two clamping plates 46 are close, the telescopic rod 44 is closed, and the control cylinder 43 retracts. The separation plate 48 squeezes the two clamping plates 46 away from each other, placing the aluminum electrolytic capacitor inside the discharge track 15, completing the unloading.

[0030] Specifically, a transmission component 5 is connected to the outer side of the feeding disc 2; the transmission component 5 includes a drive wheel 51 rotatably connected to the top of the base 11 and a driven wheel 53 rotatably connected to the bottom of the feeding track 14. The drive wheel 51 meshes with the feeding component and is fixed to the input end of the accelerator 3. The driven wheel 53 is fixed to the output end of the accelerator 3. A transmission wheel 54 is fixed to the outer side of the rotating plate 8. The driven wheel 53 and the transmission wheel 54 are connected by a toothed belt 52. The top of the connecting rod 61 is fixed. An angle bracket 62 is fixed to the output end of the feed track 14 and is located above the support plate 101. The buffer part 9 also includes two locking posts 97, which are slidably connected to the top of the hollow ring 91. An elastic element 4 is fixed to the bottom of the locking post 97 and the bottom of the elastic element 4 is fixedly connected to the hollow ring 91. The locking post 97 is located inside the support plate 101. A wedge plate 98 is fixed to the top of the hollow ring 91 and is located inside the second base plate 102.

[0031] In this embodiment, the hollow ring 91 drives the locking post 97 and the wedge plate 98 to move away from the feeding tray 2. When the hollow ring 91 contacts the support plate 101, the locking post 97 and the wedge plate 98 completely move into the inner side of the support plate 101. The second bottom plate 102 moves away from the axis of the support plate 101 under the action of the shoe surface of the wedge plate 98, releasing the restriction on the inner side of the support plate 101. At this time, the aluminum electrolytic capacitor is supported by three pulleys 96, fixed rod 95 and side rod 92. The locking post 97 prevents the next aluminum electrolytic capacitor from squeezing the aluminum electrolytic capacitor that is being fed. When the rotating plate 8 rotates to 180 degrees, and the feed tray 2 rotates until the axis of one of its top clamps aligns with the axis of the support plate 101, the damping spring 6 releases its elastic force, pushing the hollow ring 91 to move along the outside of the connecting rod 61. The side gear 93, through its meshing with the toothed plate 94, drives the side rod 92 to rotate clockwise. The side rod 92 drives the fixed rod 95 to move accordingly. When the gear moves to one-third of the distance from the top of the toothed plate 94, the three pulleys 96 are located at the bottom edge of the aluminum electrolytic capacitor. At this time, the function of the three pulleys 96, the fixed rod 95, the side rod 92, and the hollow ring 91 changes from support to clamping. When the gear moves to two-thirds of the distance from the top of the toothed plate 94, the three pulleys 96... The pulley 96 is located at the top edge of the aluminum electrolytic capacitor. At this time, the function of the three pulleys 96, the fixed rod 95, the side rod 92 and the hollow ring 91 changes from clamping to releasing. At this time, the aluminum electrolytic capacitor is completely moved into the inner side of the clamp at the top of the feeding tray 2, thereby avoiding damage to the aluminum electrolytic capacitor caused by impact and vibration due to free fall. When the gear moves to the bottom of the toothed plate 94 from its top, the three pulleys 96 are located above the top of the aluminum electrolytic capacitor. During the rotation of the rotating plate 8 by 90 degrees, the hollow ring 91 does not move to avoid the buffer part 9 from rigidly colliding with the aluminum electrolytic capacitor, while ensuring that the aluminum electrolytic capacitor falls vertically.

[0032] Elastic component one, elastic component two, and elastic component three can all be set as springs or other devices that can provide elastic force.

[0033] Specifically, the method of using the conveying device for aluminum electrolytic capacitor packaging: S1. The packaging assembly is used for the transportation and processing of aluminum electrolytic capacitors; S2, the feeding tray 2 moves the aluminum electrolytic capacitor to different stations of the packaging assembly; S3. When the aluminum electrolytic capacitor moves to the top of the buffer section 9, the rotating plate 8 uses the power of the feeding tray 2 to release the support of the buffer section 9. The buffer section 9 moves towards the feeding tray 2 under the action of the damping spring 6. The buffer section 9 goes from supporting the aluminum electrolytic capacitor, clamping the aluminum electrolytic capacitor, and finally releasing the aluminum electrolytic capacitor into the feeding plate. S4. As the feeding plate rotates, it drives the buffer part 9 back to its original position to support the next aluminum electrolytic capacitor. Repeat step S3 to complete the repeated feeding.

[0034] Working principle: Initial state as follows Figures 1-13 As shown, the feeding disc 2 drives the drive wheel 51 to rotate through meshing. The drive wheel 51 drives the driven wheel 53 to rotate through the accelerator 3. When the feeding disc 2 rotates to the point where the axis of one of its clamps is aligned with the axis of the support plate 101, the buffer part 9 moves towards the feeding disc 2 under its own gravity, and the side rod 92 drives the fixed rod 95 to move accordingly. Hollow ring 91 drives the locking post 97 and wedge plate 98 to move closer to the feeding tray 2. When hollow ring 91 contacts the first base plate 7, locking post 97 and wedge plate 98 are completely removed from the inside of support plate 101, thereby releasing the restriction on feeding track 14 and second base plate 102. Then feeding track 14 delivers aluminum electrolytic capacitors to the top of support plate 101. Then feeding tray 2 continues to rotate. During the rotation of rotating plate 8 by 90 degrees, hollow ring 91 does not move. During the rotation of rotating plate 8 from 90 degrees to 180 degrees, the device returns to its initial state. When the rotating plate 8 rotates to 180 degrees, and the feed plate 2 rotates until the axis of one of its top clamps is aligned with the axis of the support plate 101, when the gear moves to one-third of the distance from the top of the toothed plate 94, the three pulleys 96 are located at the bottom edge of the aluminum electrolytic capacitor. When the gear moves to two-thirds of the distance from the top of the toothed plate 94, the three pulleys 96 are located at the top edge of the aluminum electrolytic capacitor. At this time, the function of the three pulleys 96, the fixed rod 95, the side rod 92 and the hollow ring 91 changes from clamping to releasing. The aluminum electrolytic capacitor is completely moved into the inside of the clamp on the top of the feed plate 2. When the gear moves to the bottom of the toothed plate 94 from its top, the three pulleys 96 are located on the top of the aluminum electrolytic capacitor. After the aluminum electrolytic capacitor is completely moved into the inside of the clamp at the top of the feeding tray 2, the feeding tray 2 continues to rotate to transport the aluminum electrolytic capacitor to the inside of the waist-binding machine 12 and the sealing machine 13 for processing. The feeding tray 2 continues to rotate, conveying the aluminum electrolytic capacitor to the bottom of the discharge part 4, and placing the aluminum electrolytic capacitor inside the discharge track 15 to complete the unloading.
