Description

Technical Field

[0001] This invention relates to the field of capacitor equipment technology, and in particular to an automatic disassembly device for thin-film capacitors. Background Technology

[0002] In the manufacturing and handling of film capacitors, some products are prone to appearance defects due to collisions and friction during process flow. These defective products cannot directly enter the subsequent assembly process. To ensure product utilization, defective products need to be disassembled and reassembled. Currently, the industry generally uses manual disassembly, where operators manually peel off the product casing with simple tools such as scissors and then remove the intact internal core for reassembly. This manual operation mode has obvious limitations: on the one hand, the disassembly process relies on precise control of force and angle by humans, the labor is highly repetitive, and long-term operation can easily lead to employee fatigue and high labor intensity; on the other hand, the efficiency of manual disassembly is affected by factors such as operator proficiency and physical condition, resulting in low overall work efficiency, which is difficult to adapt to the pace requirements of large-scale production. Moreover, the lack of consistency in manual operation may cause secondary damage to the product core during disassembly, affecting the quality stability of the reassembled product. These problems all restrict the efficient advancement of the production process and urgently require an automated solution to improve it. Summary of the Invention

[0003] The present invention provides an automatic disassembly device for thin-film capacitors, which aims to solve the problem of low efficiency in the manual disassembly of defective thin-film capacitors.

[0004] In a first aspect, the present invention provides an automatic disassembly device for thin-film capacitors, comprising: A translational transport mechanism is used to transport film capacitors.

An ejection mechanism, located next to the ejection station, is used to eject the inner core of the thin-film capacitor.

[0005] Furthermore, the translational transport mechanism includes a product positioning component and a translational transport assembly. The upper surface of the product positioning component is sequentially and spaced apart from the cutting station, the shell-removing station, and the ejection station along the transport direction. The translational transport assembly is used to move along the transport direction to drive the thin film capacitor to be sequentially placed at the cutting station, the shell-removing station, and the ejection station.

[0006] Furthermore, the product positioning component has a through-hole ejection groove that extends along the transport direction and passes through at least the cutting station, the shell removal station, and the ejection station. The translational transport assembly includes a translational positioning component, a lifting component, and a translational component. The free end of the translational component is connected to the lifting component to drive the lifting component to translate along the transport direction. The free end of the lifting component is connected to the translational positioning component to drive the translational positioning component to push the thin film capacitor upward through the ejection slot from bottom to top.

[0007] Furthermore, the cutting station, the shell removal station, and the ejection station are positioning grooves formed on the product positioning component, and the groove surface of the positioning groove is adapted to the outer peripheral contour of the thin film capacitor.

[0008] Furthermore, the cutting station is provided with a rotating support member, which is used to support the outer periphery of the thin film capacitor so as to support the rotation of the thin film capacitor during cutting.

[0009] Furthermore, the product positioning component has a product guide component at one end near the cutting station, which is oriented towards the conveying direction. The product guide component is inclined downward and connected to the upper surface of the product positioning component; and / or, The product positioning component is provided with an inner core guide at one end near the ejection station, which guides the material in a direction perpendicular to the conveying direction. The inner core guide is inclined downward from the upper surface of the product positioning component.

[0010] Furthermore, the cutting mechanism includes a first lifting assembly, a rotary drive, and a cutter. The rotary drive is located at the free end of the first lifting assembly, and the first lifting assembly is used to drive the rotary drive to lift and lower. The cutter is located at the output end of the rotary drive, and the rotary drive is used to drive the cutter to rotate to cut the bottom shell of the thin-film capacitor.

[0011] Furthermore, the shell-removing mechanism includes a second lifting assembly, a gripper assembly, and a telescopic assembly. The telescopic assembly is located at the free end of the second lifting assembly, and the second lifting assembly is used to drive the telescopic assembly to move up and down. The gripper assembly is located at the free end of the telescopic assembly, and the telescopic assembly is arranged in a direction perpendicular to the conveying direction. The telescopic assembly is used to drive the gripper assembly to extend and retract toward the shell-removing station, and the gripper assembly is used to clamp or release the bottom shell.

[0012] Furthermore, the ejection mechanism includes a first positioning and pressing component and an ejection component.

The ejection component is disposed in a direction perpendicular to the transport direction and is used to extend toward the ejection station to eject the inner core of the thin film capacitor.

[0013] Furthermore, the ejection mechanism also includes a second positioning and pressing component, which is disposed above the shell removal station and extends downward to press the thin film capacitor against the shell removal station.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, the directional terms used are for illustrating and understanding this invention, and not for limiting it.

[0019] As a key component in electronic devices, film capacitors undergo multiple processes during manufacturing and handling. During this process, products are prone to appearance defects due to collisions and impacts during equipment transfers and workstation handovers. To avoid resource waste, these defective products need to be disassembled and their intact internal cores removed for reuse. Currently, the industry primarily relies on manual operation for disassembling such defective products. Operators must manually peel off the product casing using simple tools like scissors. This process is not only cumbersome and repetitive, leading to high labor intensity for employees, but also susceptible to subjective factors such as operator skill and physical condition, making it difficult to improve disassembly efficiency. This fails to meet the demands of efficient large-scale production and has become a prominent issue hindering production process optimization and cost control.

[0020] Therefore, this application proposes an automated film capacitor disassembly device. By incorporating a translation and transport mechanism, a cutting mechanism, a shell-removing mechanism, and an ejection mechanism, it automates the disassembly of the film capacitor casing and removes the inner core, replacing manual labor. This significantly reduces manual intervention, improves the consistency of the work rhythm, and thus achieves high efficiency, standardization, and large-scale operation of the film capacitor disassembly process. Ultimately, it significantly improves disassembly efficiency, reduces labor intensity, and ensures stable disassembly quality. Details are as follows: Please see Figures 1 to 8 , Figure 1 An automatic disassembly device for a thin-film capacitor 5, as proposed in an embodiment of the present invention, includes: a translational transport mechanism 1, a cutting mechanism 2, a shell removal mechanism 3, and an ejection mechanism 4. The translational transport mechanism 1 is used to transport the thin-film capacitor 5, and is sequentially provided with a cutting station 111, a shell removal station 112, and an ejection station 113 for placing the thin-film capacitor 5 along the transport direction of the translational transport mechanism 1; the cutting mechanism 2 is located next to the cutting station 111 and is used to cut the bottom shell of the thin-film capacitor 5; the shell removal mechanism 3 is located next to the shell removal station 112 and is used to remove the bottom shell of the thin-film capacitor 5; the ejection mechanism 4 is located next to the ejection station 113 and is used to eject the inner core of the thin-film capacitor 5.

[0021] Specifically, the translational transport mechanism 1 is used to realize the orderly transfer of the film capacitor 5 between different workstations. It has a stable bearing structure and precise displacement adjustment capability, which can smoothly lift and transport the film capacitor 5, ensuring that the product will not be shifted or damaged during the transport process. The transport path of this mechanism is sequentially set with a cutting workstation 111, a shell removal workstation 112, and an ejection workstation 113. Each workstation corresponds to a different subsequent disassembly process. The translational transport mechanism 1 maintains a preset positional correspondence with the cutting mechanism 2, the shell removal mechanism 3, and the ejection mechanism 4. The process is connected through the coordinated action of each mechanism. It can be implemented in various ways, such as a cylinder-driven translational structure, a motor-driven lead screw and slider structure, or a belt conveyor structure, to meet different transport efficiency and accuracy requirements. No limitation is made here. Throughout the disassembly process, after the film capacitor 5 flows into the translation and transport mechanism 1 from the upstream process, the mechanism first accurately transports the product to the cutting station 111. After the cutting process is completed, the product is then transferred to the shell removal station 112. After the shell removal process is completed, the product continues to be transported to the ejection station 113 until the core ejection process is completed, thus realizing the automated flow of the product between each station.

[0022] The cutting mechanism 2 is used to precisely cut the bottom shell of the film capacitor 5. Its structure can be implemented in various ways, and is not limited here. The bottom shell is the bottom of the film capacitor 5 housing. Optionally, the cutting mechanism 2 mainly includes a power output component, a cutting execution component, and a mounting and fixing component. The power output component provides stable rotational power, the cutting execution component has a sharp cutting edge to ensure cutting effect, and the mounting and fixing component is used to securely assemble the entire cutting mechanism 2. This mechanism is located next to the cutting station 111, corresponding to the position of the translation and transport mechanism 1, ensuring that the film capacitor 5 transported by the translation and transport mechanism 1 to the cutting station 111 can be accurately aligned with the cutting execution component. Its power output component can be a stepper motor, servo motor, or other types. The cutting execution component can be a disc cutter 23, a ring cutter 23, or other different structures. The mounting and fixing component is fixed to the equipment frame by bolts or other connecting parts to ensure structural stability during the cutting process. During the disassembly operation, after the translation and transport mechanism 1 delivers the film capacitor 5 to the cutting station 111 and completes the positioning, the power output component of the cutting mechanism 2 is activated, driving the cutting execution component to rotate at high speed. At the same time, the lifting component of the cutting mechanism 2 drives the cutting execution component to approach the bottom shell of the film capacitor 5 until the cutting edge contacts the bottom shell and completes the cutting. After the cutting is completed, the lifting component drives the cutting execution component to reset, waiting for the next cutting operation.

[0023] The shell-removing mechanism 3 is used to pull the cut bottom shell of the film capacitor 5 from the inner core. Its structure can be implemented in various ways, and is not limited here. Optionally, the shell-removing mechanism 3 mainly includes a clamping component, a driving component, and a guiding adjustment component. The clamping component reliably clamps the bottom shell, the driving component provides sufficient pulling force, and the guiding adjustment component ensures smooth and precise shell-removing action. This mechanism is located next to the shell-removing station 112 and cooperates with the transfer path of the translational conveying mechanism 1. The clamping range of the clamping component can be adjusted according to different specifications of the bottom shell of the film capacitor 5. The driving component can adopt various driving methods such as cylinders, hydraulic cylinders, or electric push rods. The guiding adjustment component achieves lifting and horizontal position adjustment through the cooperation of a slider and a guide rail, ensuring that the clamping component can accurately align and clamp the bottom shell. When the film capacitor 5 is sent to the shell removal station 112 by the translation and conveying mechanism 1 after the cutting process, the guide adjustment component of the shell removal mechanism 3 drives the clamping component to move to the bottom shell position. The clamping component closes and clamps the bottom shell. Then the drive component starts, driving the clamping component to move away from the inner core and pull the bottom shell out of the inner core. After the shell removal is completed, the clamping component is released, the bottom shell is collected or discharged, and the clamping component is reset under the action of the guide adjustment component, ready for the next shell removal operation.

[0024] The ejection mechanism 4 is used to eject the inner core of the film capacitor 5 from the remaining housing. Its structure can be implemented in various ways and is not limited here. Optionally, the ejection mechanism 4 mainly consists of a power drive component, an ejection execution component, and a positioning auxiliary component. The power drive component provides a smooth linear thrust, the end face of the ejection execution component that contacts the inner core is flat and smooth to avoid damage to the inner core, and the positioning auxiliary component is used to fix and limit the product during the ejection process. This mechanism is located next to the ejection station 113, corresponding to the position of the product transported to this station by the translation and conveying mechanism 1. The power drive component can be of different types, such as a cylinder or an electric cylinder. The ejection execution component can be designed as a push rod, push plate, or other structures. The positioning auxiliary component cooperates with the positioning structure of the translation and conveying mechanism 1 to ensure that the product remains stable during the ejection process. During the disassembly process, after the uncased film capacitor 5 is transported to the ejection station 113 by the translation and transport mechanism 1, the positioning auxiliary component first clamps and positions the product to prevent the product from shifting during the ejection process. Then, the power drive component is activated, driving the ejection execution component to extend into the product and smoothly eject the inner core from the shell. After the inner core is ejected, it falls into the preset collection device. The ejection execution component is reset under the action of the power drive component, and the positioning auxiliary component is released, completing one ejection operation.

[0025] Specifically, this embodiment constructs a complete automated disassembly process by setting up a translational transport mechanism 1, a cutting mechanism 2, a shell removal mechanism 3, and an ejection mechanism 4, and rationally distributing the positional relationships and coordinated actions of each mechanism, replacing the traditional manual disassembly method. The translational transport mechanism 1 realizes the automatic transfer of products between workstations, avoiding the tediousness and inefficiency of manual handling; the cutting mechanism 2 and the shell removal mechanism 3 respectively complete the precise cutting and reliable removal of the bottom shell, eliminating the need for manual operation with scissors or other tools, thus reducing labor intensity; the ejection mechanism 4 realizes the smooth ejection of the inner core, ensuring the integrity of the inner core. Each mechanism has a clear division of labor and works in concert, requiring no manual intervention throughout the process, effectively solving the technical problems of high labor intensity, low production efficiency, and easy damage to the inner core during traditional manual disassembly. Through this design, not only is the disassembly of defective film capacitors 5 automated, but the stability and reliability of the disassembly process are also improved, reducing reliance on manual labor, while ensuring the quality of the reassembled product, thereby achieving the technical effects of optimizing the production process and improving production efficiency.

[0026] Reference Figure 2 In one embodiment, the translational transport mechanism 1 includes a product positioning component 11 and a translational transport assembly. The upper surface of the product positioning component 11 is sequentially and spaced apart along the transport direction by the cutting station 111, the shell removal station 112, and the ejection station 113. The translational transport assembly is used to move along the transport direction to drive the thin film capacitor 5 to be sequentially placed at the cutting station 111, the shell removal station 112, and the ejection station 113.

[0027] Specifically, the translational transport mechanism 1 includes a product positioning component 11 and a translational transport assembly. The product positioning component 11 is a long strip-shaped structure with a flat upper surface. Its main function is to provide a stable placement and positioning base for the film capacitor 5. The translational transport assembly has the power output capability and positioning accuracy to drive the film capacitor 5 to move, and is used to drive the product to flow between different workstations. The structure of the translational transport assembly can be implemented in various ways, and is not limited here. The upper surface of the product positioning component 11 is arranged with cutting workstation 111, shell removal workstation 112 and ejection workstation 113 at intervals along the transport direction. The workstations are arranged in a straight line and the spacing is adapted to the movement stroke of the disassembly process. The translational transport assembly is set below or to the side of the product positioning component 11, and maintains a preset positional correspondence with the product positioning component 11, and can accurately act on the film capacitor 5 on the product positioning component 11.

[0028] During the entire disassembly process, the film capacitor 5 is first conveyed to the initial position of the product positioning component 11. The translational transport component then activates and cooperates with the product positioning component 11 to move the product from the initial position to the cutting station 111. After the cutting process is completed, the translational transport component activates again, sequentially transferring the product to the shell removal station 112 and the ejection station 113, until all disassembly processes are completed. The product positioning component 11 provides a stable support and positioning base, while the translational transport component provides precise movement power, ensuring the orderly flow of the film capacitor 5 between each station and preventing product displacement or damage during transport, thereby guaranteeing the smoothness and efficiency of the entire disassembly process.

[0029] Reference Figure 3 and 4 In this embodiment, the product positioning member 11 has a vertically penetrating ejection groove 114. The ejection groove 114 extends along the transport direction and passes through at least the cutting station 111, the shell removal station 112, and the ejection station 113. The translation transport assembly includes a translation positioning member 12, a lifting assembly 13, and a translation assembly 14. The free end of the translation assembly 14 is connected to the lifting assembly 13 to drive the lifting assembly 13 to translate along the transport direction. The free end of the lifting assembly 13 is connected to the translation positioning member 12 to drive the translation positioning member 12 to push the thin film capacitor 5 upward through the ejection groove 114 from bottom to top.

[0030] Specifically, the product positioning component 11 has a through-hole ejection groove 114, which extends along the transport direction and covers the cutting station 111, the shelling station 112, and the ejection station 113. The ejection groove 114 is a long groove, the width of which is adapted to the size of the translation positioning component 12, providing a channel for the lifting and traversing of the translation positioning component 12. The translation transport assembly includes a lifting component 13 and a traversing component 14. The translation positioning component 12 has a long strip structure with a positioning structure, such as a V-groove structure, on its upper part that contacts the product. The lifting component 13 uses a cylinder-driven structure to provide vertical lifting power, while the traversing component 14 can use a cylinder-driven, screw-driven, or slide rail structure to provide horizontal traversing power. The free end of the translation component 14 is fixedly connected to the lifting component 13, and the free end of the lifting component 13 is fixedly connected to the translation positioning component 12. The three form a linkage structure. The translation positioning component 12 can pass through the ejection slot 114 from bottom to top under the drive of the lifting component 13 and lift the thin film capacitor 5 on the product positioning component 11.

[0031] During the disassembly process, after the film capacitor 5 is placed on the product positioning component 11, the lifting component 13 is activated, which drives the translation positioning component 12 to move upward through the ejection slot 114, lifting the product and separating it from the upper surface of the product positioning component 11. Then, the translation component 14 moves, which drives the lifting component 13 and the translation positioning component 12 to move along the transport direction, transferring the product to the target workstation. The lifting component 13 resets, which drives the translation positioning component 12 to descend, and the product falls on the corresponding workstation of the product positioning component 11. The translation component 14 then resets again, which drives the lifting component 13 and the translation positioning component 12 back to the initial position, completing one transfer operation.

[0032] By setting up a combined structure of ejector slot 114 and translation positioning component 12, lifting component 13 and translation component 14, the problems of interference with products and insufficient transfer accuracy of traditional handling mechanisms are solved. The ejector slot 114 provides movement space for translation positioning component 12, and the linkage of lifting component 13 and translation component 14 realizes the smooth lifting and translation of products, avoiding collisions between products and other components during transfer. Precise position control ensures that products can accurately reach each workstation, thereby improving the stability and accuracy of the handling process.

[0033] In this embodiment, the cutting station 111, the shell removal station 112, and the ejection station 113 are positioning grooves formed on the product positioning component 11, and the groove surface of the positioning groove is adapted to the outer peripheral contour of the thin film capacitor 5.

[0034] Specifically, the cutting station 111, the shell removal station 112, and the ejection station 113 are all positioning grooves formed on the product positioning component 11. The groove surface of the positioning groove is an arc-shaped curved surface or a V-shaped groove surface that conforms to the outer peripheral contour of the film capacitor 5, which can form a circumferential limit on the film capacitor 5 and prevent the product from rotating or shifting during the corresponding process. The positioning grooves are arranged sequentially along the transport direction of the product positioning component 11, and the spacing between adjacent grooves matches the translation stroke of the translation transport component, ensuring that the translation transport component can accurately transfer the product from one groove to the next groove.

[0035] During the disassembly process, the film capacitor 5 is transferred to the positioning groove of the cutting station 111 by the translation and transport assembly. The positioning groove fixes the product circumferentially, providing stable support for the cutting action of the cutting mechanism 2. After the cutting is completed, the translation and transport assembly transfers the product to the positioning groove of the shell removal station 112. This groove also limits the product, ensuring that the shell removal mechanism 3 can accurately clamp the bottom shell and pull it out smoothly. After the shell removal is completed, the product is transferred to the positioning groove of the ejection station 113. The groove continues to fix the product, ensuring that the ejection mechanism 4 can smoothly eject the inner core.

[0036] By setting each workstation with a positioning groove that matches the outer contour of the product, the problem of unstable positioning of the product during each process is solved. The positioning groove can reliably limit the circumferential position of the film capacitor 5, preventing the product from shifting or shaking during the process, thereby improving the execution effect and reliability of each disassembly process.

[0037] Reference Figure 5 In this embodiment, the cutting station 111 is provided with a rotating support 15, which is used to support the outer periphery of the thin film capacitor 5 so as to support the rotation of the thin film capacitor 5 during cutting.

[0038] Specifically, the cutting station 111 is equipped with a rotating support 15, which can be constructed using multiple rolling bearings or rollers. These bearings are evenly distributed on the groove wall of the positioning groove in the cutting station 111. The rolling surfaces of the bearings protrude from the groove wall surface and contact the outer periphery of the film capacitor 5. They are used to support the smooth rotation of the product when the cutting mechanism 2 cuts the product's bottom shell. The rotating support 15 is connected to the positioning groove of the cutting station 111, and the bearing installation direction is adapted to the product's rotation direction, ensuring that the product can rotate along its own axis under the support of the bearings. Furthermore, the number and distribution of the bearings ensure uniform force on the product, preventing excessive localized force that could damage the product.

[0039] During the disassembly process, when the film capacitor 5 is moved into the positioning groove of the cutting station 111, the outer periphery of the product is in close contact with the rolling surface of the bearing of the rotating support 15. When the cutter 23 of the cutting mechanism 2 contacts the bottom shell of the product and drives the product to rotate, the bearing of the rotating support 15 rolls accordingly, providing support for the rotation of the product and reducing friction, so that the product can rotate smoothly and at a uniform speed, ensuring that the bottom shell is cut evenly.

[0040] By setting a rotating support 15 in the form of a rolling bearing at the cutting station 111, the problem of uneven cutting of the bottom shell caused by the product's uneven rotation during the cutting process is solved. The rolling bearing can effectively reduce the frictional resistance when the product rotates, ensuring that the product rotates smoothly during cutting, so that the cutter 23 can cut evenly along the circumference of the bottom shell, avoiding incomplete cutting or product damage. By improving the uniformity and integrity of the cutting, the smooth progress of the subsequent shell removal process is ensured.

[0041] Reference Figure 2In this embodiment, the product positioning member 11 is provided with a product guide member 16 facing the conveying direction at one end near the cutting station 111. The product guide member 16 is inclined downward and connected to the upper surface of the product positioning member 11; and / or, the product positioning member 11 is provided with an inner core guide member 17 facing the direction perpendicular to the conveying direction at one end near the ejection station 113. The inner core guide member 17 is inclined downward from the upper surface of the product positioning member 11.

[0042] Specifically, a product guide 16 is provided at the end of the product positioning component 11 near the cutting station 111. The product guide 16 has a channel-shaped structure and is inclined downwards in the transport direction. Its lower end is connected to the upper surface of the product positioning component 11, forming a smooth guide channel for guiding the film capacitor 5 from the upstream process onto the product positioning component 11. Simultaneously, an inner core guide 17 is provided at the end of the product positioning component 11 near the ejection station 113. The inner core guide 17 also has a channel-shaped structure and is inclined downwards in a direction perpendicular to the transport direction. Its upper end is connected to the upper surface of the product positioning component 11 for guiding the inner core ejected by the ejection mechanism 4 to a preset collection area. The product guide 16 is fixedly connected to the product positioning component 11, and its inclination angle ensures that the product smoothly slides to the initial position of the product positioning component 11 under gravity. The inner core guide 17 is also fixedly connected to the product positioning component 11, and its inclination angle can be adjusted according to the inner core collection requirements.

[0043] During the disassembly process, the film capacitor 5 from the upstream process is guided by the product guide 16 and smoothly slides to the initial position of the product positioning component 11, waiting for the translation and transportation component to transfer it. When the ejection mechanism 4 pushes the inner core out of the product shell, the inner core slides down along the inner core guide 17 under the action of gravity and enters the designated collection area to complete the collection of the inner core.

[0044] By setting up product guide component 16 and inner core guide component 17, the problems of jamming or falling during product feeding and inner core collection are solved. Product guide component 16 provides a smooth feeding channel for upstream products, ensuring that products can accurately enter the subsequent transfer process. Inner core guide component 17 provides a stable collection channel for the ejected inner cores, avoiding the scattering or damage of the inner cores. By realizing automated guidance for feeding and collection, the automation level and operating efficiency of the entire dismantling equipment are improved.

[0045] Reference Figure 6In one embodiment, the cutting mechanism 2 includes a first lifting component 21, a rotary drive component 22, and a cutter 23. The rotary drive component 22 is located at the free end of the first lifting component 21, and the first lifting component 21 is used to drive the rotary drive component 22 to lift and lower. The cutter 23 is located at the output end of the rotary drive component 22, and the rotary drive component 22 is used to drive the cutter 23 to rotate to cut the bottom shell of the thin film capacitor 5.

[0046] Specifically, the cutting mechanism 2 includes a first lifting assembly 21, a rotary drive component 22, and a cutter 23. The first lifting assembly 21 adopts a cylinder-guided slide rail drive structure, providing stable lifting power output. It drives the rotary drive component 22 and the cutter 23 to achieve vertical position adjustment. The rotary drive component 22 is a stepper motor or servo motor, providing continuous and controllable rotational power. The cutter 23 is a circular structure with a sharp cutting edge, used to directly contact and cut the bottom shell of the film capacitor 5. The first lifting assembly 21 is securely connected to the equipment frame via a fixed base. The rotary drive component 22 is fixedly installed at the free end of the first lifting assembly 21 and rises and falls synchronously with the first lifting assembly 21. The cutter 23 is detachably installed on the output shaft of the rotary drive component 22, ensuring high-speed rotation and preventing loosening during the cutting process. The entire cutting mechanism 2 is located next to the cutting station 111, precisely corresponding to the position of the film capacitor 5 transported to the station by the translation and conveying mechanism 1.

[0047] During the disassembly process, after the translation and transport mechanism 1 delivers the film capacitor 5 to the cutting station 111 and completes its positioning, the rotary drive component 22 is activated, driving the cutter 23 to rotate at high speed. Subsequently, the first lifting component 21 is activated, driving the rotary drive component 22 and the cutter 23 to descend towards the bottom shell of the film capacitor 5. After the cutter 23 contacts the bottom shell, it completes the bottom shell cutting under the combined action of rotational force and downward pressure. After the cutting is completed, the first lifting component 21 drives the rotary drive component 22 and the cutter 23 to rise and reset. The rotary drive component 22 stops working and waits for the next cutting operation.

[0048] The combination structure of the first lifting component 21, the rotary drive component 22, and the cutter 23 solves the problems of low efficiency and unstable cutting quality of manual cutting. The rotary drive component 22 provides stable rotational power, the first lifting component 21 precisely controls the cutting depth and force, and the cutter 23 ensures the cutting effect. The three work together to achieve automated and precise cutting of the bottom shell. By avoiding the subjectivity and limitations of manual operation, the consistency and reliability of the cutting process are ensured, laying a good foundation for the subsequent shell removal process.

[0049] Reference Figure 7In one embodiment, the shell-removing mechanism 3 includes a second lifting assembly 31, a gripper assembly 32, and a telescopic assembly 33. The telescopic assembly 33 is located at the free end of the second lifting assembly 31, and the second lifting assembly 31 is used to drive the telescopic assembly 33 to rise and fall. The gripper assembly 32 is located at the free end of the telescopic assembly 33. The telescopic assembly 33 is arranged in a direction perpendicular to the conveying direction. The telescopic assembly 33 is used to drive the gripper assembly 32 to extend and retract toward the shell-removing station 112. The gripper assembly 32 is used to clamp or release the bottom shell.

[0050] Specifically, the shell-removing mechanism 3 includes a second lifting component 31, a gripper component 32, and a telescopic component 33. The second lifting component 31 can achieve smooth lifting and lowering movements and is used to adjust the height position of the gripper component 32. The telescopic component 33 can be a cylinder or an electric push rod, and is set in a direction perpendicular to the transport direction, with precise telescopic stroke control capability. The gripper component 32 includes a gripper cylinder 321 and a clamping member 322. The contact surface of the clamping member 322 is adapted to the shape of the bottom shell and is used to reliably clamp or release the bottom shell. The second lifting assembly 31 is connected to the equipment frame via a fixed base. It employs a structure consisting of an adjusting handwheel 311, a threaded rod, a fixed base 312, and a guide rail 313. The fixed base 312 is fixed to the equipment frame and has a guide rail 313 with a threaded hole. The center of the adjusting handwheel 311 is connected to the threaded rod, which passes vertically through the threaded hole and connects to a slider 314 on the guide rail 313. The slider 314 serves as a free end, and its height can be adjusted by rotating the adjusting handwheel 311. The telescopic assembly 33 is fixedly installed at the free end of the second lifting assembly 31 and rises and falls synchronously with it. The gripper assembly 32 is installed at the free end of the telescopic assembly 33 and can move towards or away from the shell removal station 112 under the drive of the telescopic assembly 33. The shell removal mechanism 3 is positioned beside the shell removal station 112, corresponding to the position of the translational conveying mechanism 1, ensuring that the gripper assembly 32 can accurately align with the bottom shell of the thin-film capacitor 5 on the shell removal station 112.

[0051] During the disassembly process, after the film capacitor 5 is cut, it is transferred to the shell removal station 112. The second lifting component 31 is activated first, which drives the telescopic component 33 and the gripper component 32 to adjust to the height corresponding to the bottom shell. Then the telescopic component 33 extends and pushes the gripper component 32 closes to clamp the bottom shell. Then the telescopic component 33 retracts, which drives the gripper component 32 and the bottom shell to move away from the inner core, and pulls the bottom shell out of the inner core. After the shell removal is completed, the gripper component 32 is released and the bottom shell is discharged or collected. The telescopic component 33 and the second lifting component 31 are reset in sequence, ready for the next shell removal operation.

[0052] By setting up a linkage structure of the second lifting component 31, the gripper component 32, and the telescopic component 33, the problems of high labor intensity and easy damage to the inner core during manual shell removal are solved. The position of the gripper component 32 is precisely adjusted by the second lifting component 31 and the telescopic component 33, and the gripper component 32 reliably holds the bottom shell, realizing the automatic removal of the bottom shell. By avoiding the brute force of manual operation, the integrity of the inner core is protected, while improving shell removal efficiency and operational stability.

[0053] Reference Figure 8 In one embodiment, the ejection mechanism 4 includes a first positioning and pressing component 41 and an ejection component 43. The first positioning and pressing component 41 is disposed above the ejection station 113 and is used to extend downward to press the thin film capacitor 5 against the ejection station 113. The ejection component 43 is arranged in a direction perpendicular to the transport direction and is used to extend toward the ejection station 113 to eject the inner core of the thin film capacitor 5.

[0054] Specifically, the ejection mechanism 4 includes a first positioning and clamping assembly 41 and an ejection assembly 43. The first positioning and clamping assembly 41 may consist of a positioning cylinder 401 and a positioning pressure head 402. The positioning pressure head 402 is made of flexible material to avoid damaging the product during clamping and is used to press and fix the film capacitor 5 to the ejection station 113. The ejection assembly 43 includes an ejection cylinder and an ejection end, which is set in a direction perpendicular to the transport direction to provide a smooth thrust to eject the inner core. The first positioning and clamping assembly 41 is installed above the ejection station 113 and fixed to the equipment frame by a support plate and a fixing seat. Its output direction is vertically downward and corresponds to the position of the ejection station 113. The ejection assembly 43 is set on one side of the ejection station 113, and its extension and retraction direction is towards the ejection station 113. The ejection end corresponds to the end face of the inner core of the film capacitor 5.

[0055] During the disassembly process, after the uncased film capacitor 5 is transferred to the ejection station 113, the positioning cylinder 401 of the first positioning and pressing component 41 is activated, driving the positioning and pressing head 402 to extend downward and press the film capacitor 5 onto the ejection station 113 to prevent the product from shifting during the ejection process. Subsequently, the ejection cylinder of the ejection component 43 is activated, driving the ejection end to extend into the product. The ejection end contacts the inner core end face and applies a pushing force to smoothly eject the inner core from the remaining shell. After the inner core is ejected, the ejection component 43 and the first positioning and pressing component 41 are reset in sequence, waiting for the next ejection operation.

[0056] The cooperation of the first positioning and clamping component 41 and the ejection component 43 solves the problem of unstable product positioning during core ejection, which leads to unsmooth or damaged core ejection. The first positioning and clamping component 41 provides a reliable fixing effect, and the ejection component 43 provides a smooth ejection force. The two work together to achieve automated core ejection. By ensuring the stability and smoothness of the core ejection process, the integrity of the core is guaranteed, providing a good core product for subsequent reassembly operations.

[0057] In this embodiment, the ejection mechanism 4 further includes a second positioning and pressing component 42, which is disposed above the shell removal station 112. The second positioning and pressing component 42 is used to extend downward to press the thin film capacitor 5 against the shell removal station 112.

[0058] Specifically, the ejection mechanism 4 also includes a second positioning and clamping assembly 42, which is arranged adjacent to the first positioning and clamping assembly 41 and both are mounted on the same support plate. The structure of the second positioning and clamping assembly 42 is the same as that of the first positioning and clamping assembly 41, consisting of a positioning cylinder 401 and a positioning pressure head 402. The positioning pressure head 402 is made of flexible material and has good buffering performance, used to clamp and fix the film capacitor 5 during the shell removal process. The second positioning and clamping assembly 42 is installed above the shell removal station 112 and is fixed to the equipment frame by a support plate and a fixing seat. Its output direction is vertically downward, corresponding to the position of the shell removal station 112, and can accurately align the film capacitor 5 transferred to the station. It forms an upper and lower cooperation relationship with the gripper assembly 32 of the shell removal mechanism 3, and works together on the film capacitor 5.

[0059] During the disassembly process, after the film capacitor 5 is transferred to the shell removal station 112, the positioning cylinder 401 of the second positioning and pressing component 42 is activated, which drives the positioning pressure head 402 to extend downward and press the film capacitor 5 onto the shell removal station 112 to ensure that the product will not shake or shift during the shell removal process. Then, the gripper component 32 of the shell removal mechanism 3 clamps the bottom shell and performs the shell removal action. After the shell removal is completed, the positioning cylinder 401 of the second positioning and pressing component 42 is reset, which drives the positioning pressure head 402 to retract upward and release the product for subsequent transfer.

[0060] By adding a second positioning and clamping component 42, the problem of product instability during the shell removal process, which leads to difficulties in shell removal or product damage, is solved. The second positioning and clamping component 42 works in conjunction with the shell removal mechanism 3 to reliably fix the product during shell removal, preventing the product from shifting or rotating during the process. By improving the positioning stability of the shell removal process, the shell removal action can be carried out smoothly, reducing damage to the product shell and inner core during the shell removal process and ensuring the overall quality of the disassembly operation.

[0061] To further understand the automatic disassembly device for the thin-film capacitor 5 in this embodiment of the invention, the entire disassembly process of the thin-film capacitor 5 will be described below.

[0062] The film capacitor 5, transferred from the previous process, automatically flows into the product guide 16 of the translation conveying mechanism 1, and is precisely guided into the initial position of the product positioning component 11. Once the equipment senses the product's arrival, the lifting component 13 of the translation conveying assembly immediately moves, lifting the translation positioning component 12 upwards, simultaneously stabilizing the film capacitor 5 within the positioning structure of the translation positioning component 12. After the lifting component 13 rises to the preset high position, the translation component 14 extends, driving the lifting component 13, the translation positioning component 12, and the film capacitor 5 on them to move along the conveying direction until the product is transported above the cutting station 111. Then, the lifting component 13 retracts to its original position, the film capacitor 5 is stably placed on the cutting station 111 of the product positioning component 11, and the translation component 14 also retracts to its initial position, completing the transfer of the product to the cutting station 111.

[0063] Once the film capacitor 5 is positioned at the cutting station 111, the cutting mechanism 2 begins operation. The rotary drive component 22 of the cutting mechanism 2 starts running, driving the cutter 23 to rotate at high speed. Simultaneously, the first lifting component 21 actuates, driving the rotary drive component 22 and the cutter 23 downwards, causing the rotating cutter 23 to gradually approach the bottom shell of the film capacitor 5. Because the cutting station 111 is equipped with a rotating support component 15, which provides rotational support for the film capacitor 5, when the rotating cutter 23 contacts the film capacitor 5, it causes the product to rotate synchronously. Under the combined action of the continuous downward pressure applied by the first lifting component 21 and the rotational cutting force of the cutter 23, the bottom shell of the film capacitor 5 is precisely cut. After cutting, the first lifting component 21 drives the rotary drive component 22 and the cutter 23 to retract upwards to their original positions, the rotary drive component 22 stops operating, and the cutting process ends.

[0064] After the cutting process is completed, the lifting component 13 of the translation and conveying assembly extends upward again, lifting the translation positioning component 12 and positioning the film capacitor 5 in the positioning structure of the translation positioning component 12. After the lifting component 13 rises to the preset high position, the translation component 14 extends again, moving the lifting component 13, the translation positioning component 12, and the film capacitor 5 to above the shell removal station 112. Then, the lifting component 13 retracts, and the film capacitor 5 is placed on the shell removal station 112 of the product positioning component 11. The translation component 14 then resets. At this time, the second positioning and pressing component 42 actuates, causing the positioning and pressing head 402 to extend downward, pressing the film capacitor 5 onto the shell removal station 112. The shell-removing mechanism 3 begins operation. The second lifting component 31 first adjusts its height according to the product specifications to ensure that the gripper component 32 can accurately align with the bottom shell. Then, the telescopic component 33 extends, pushing the gripper component 32 closer to the bottom shell. The gripper component 32 closes and clamps the bottom shell. Next, the telescopic component 33 retracts, moving the gripper component 32 and the bottom shell away from the inner core, completely removing the bottom shell. After shell removal is complete, the gripper component 32 releases, and the bottom shell is discharged or collected. The telescopic component 33, the second lifting component 31, and the second positioning and clamping component 42 then reset sequentially, awaiting the next operation.

[0065] After the shell removal process is completed, the lifting component 13 of the translation and conveying assembly moves again to lift the translation positioning component 12, positioning the film capacitor 5 after the bottom shell has been removed. The translation component 14 drives it to move above the ejection station 113 and place it in place. The ejection mechanism 4 is activated, and the positioning cylinder 401 of the first positioning and pressing component 41 is activated, driving the positioning pressing head 402 to extend downward, pressing and fixing the film capacitor 5 on the ejection station 113 to prevent the product from shifting during the ejection process. Subsequently, the inner core ejection cylinder of the ejection component 43 is activated, pushing the ejection execution component, i.e., the ejection end, to extend into the film capacitor 5. The ejection end contacts the inner core end face and applies a smooth pushing force, smoothly ejecting the inner core from the remaining shell. The ejected inner core slides down the inner core guide component 17 to the preset collection area, completing the collection of the inner core. Finally, the ejection component 43 and the first positioning and pressing component 41 are reset in sequence, and the entire disassembly process of the film capacitor 5 is completed. The equipment waits for the next product to enter the disassembly cycle.

Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention.
