Description

Technical Field

[0001] This invention belongs to the field of capacitor manufacturing technology, specifically relating to an integrated packaging device for dry film capacitors and its usage method. Background Technology

[0002] Dry-type film capacitors use metallized polypropylene film as the dielectric, featuring small size, light weight, low loss, and excellent insulation performance. They are widely used in demanding applications such as flexible DC power transmission and frequency converters. Their structure has no liquid dielectric, resulting in high safety, strong environmental protection, and low maintenance costs. Impregnation sealing is a common type of capacitor encapsulation. It involves immersing the capacitor element in insulating oil or impregnating agent to enhance its electrical performance and stability, while forming a solid seal on the outer layer to provide good mechanical protection and environmental adaptability.

[0003] A Chinese invention patent with publication number CN114628158A discloses a stacked electrolytic capacitor packaging device and method. This method involves setting up a core winding and forming device to first wind electrolytic paper tape into an electrolytic paper roll, then cutting the electrolytic paper roll into left and right parts, flattening and stacking the two parts to form a capacitor core, inserting the capacitor core into a capacitor casing, and finally assembling a positive electrode cap to complete the electrolytic capacitor packaging process. In the production of pin-type film capacitors, one end of the pin is flattened and welded to both ends of the core, then the pin is clamped while the core is immersed in an impregnating agent for coating, and finally cured to complete the packaging. However, clamping the pin can easily pull on the core's welding position, leading to poor connection or even short circuit, affecting the subsequent yield. Therefore, this invention provides an integrated packaging device for dry-type film capacitors and its usage method. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an integrated packaging device for dry film capacitors and its usage method.

[0005] The technical solution adopted to solve the above technical problems is: An integrated packaging device for dry film capacitors, comprising: The feeding mechanism includes a horizontally arranged guide rail, a support plate movably disposed in the middle of the guide rail, and a pusher disposed at the end of the guide rail; The auxiliary mechanism includes a platform, the platform having a notch at the end corresponding to the guide rail that mates with the bearing plate, and a movable plate movably mounted above the platform along the height direction, the movable plate having a receiving cavity in the middle; A transverse movement mechanism 1 includes a three-degree-of-freedom horizontal moving platform, a pickup head is installed at the free end of the three-degree-of-freedom horizontal moving platform, and a jetting component is coaxially provided on the outer side of the pickup head; The curing mechanism includes a chain conveyor, wherein a placement plate with a placement groove is installed on the outer circumference of the chain conveyor, and a curing lamp is provided directly above the placement plate; The second transverse movement mechanism includes a two-degree-of-freedom moving stage, wherein a contact head is installed on the free end of the two-degree-of-freedom moving stage; The impregnation mechanism includes a three-degree-of-freedom rotary table, an impregnation clamp is installed at the free end of the three-degree-of-freedom rotary table, and an open material box is provided below the impregnation clamp; The settling mechanism includes a two-degree-of-freedom moving stage 2, a negative pressure head installed at the free end of the two-degree-of-freedom moving stage 2, a guide platform provided below the negative pressure head, a conveying component embedded in the middle of the guide platform, and a receiving component slidably installed on the upper part of the guide platform.

[0006] The feeding mechanism and auxiliary mechanism work together to place the carrier plate containing the core under the moving plate and press it down. The first transverse mechanism works with the moving plate to pick up the core and apply UV paint. The core is then transported to the second transverse mechanism by the curing mechanism. During the transport process, the UV paint will cure and fix the core and pin to each other, ensuring that the welding position will not crack and cause a short circuit when the core is impregnated later. The second transverse mechanism transfers the core to the impregnation mechanism. The impregnation clamp holds the support segment and immerses the core and welding segment in the impregnating agent. The core is then placed vertically with its face upward until the impregnating agent cures into an outer layer. During the process, an extension will also be formed, increasing the contact area between the cured outer layer and the support segment. This ensures that the transition segment of the pin is completely wrapped and is not easily twisted or broken when the part is used in the later processing.

[0007] Furthermore, the pusher includes a telescopic cylinder, the end of which is provided with a straight plate, and a baffle is provided at the edge of the guide rail along the sliding direction of the straight plate, and the end of the bearing plate slides in contact with the vertical side wall of the baffle.

[0008] Through the above technical solution, in order to ensure the smooth pushing of the carrier plate, the telescopic cylinder adopts an electro-hydraulic actuator, which can extend and retract horizontally. The straight plate is flush with the carrier plate, which can push the long strip-shaped carrier plate to move along the guide rail. The straight plate is the same length as the carrier plate and contacts the long side of the carrier plate. Under the limitation of the baffle, it can ensure that the carrier plate is smoothly pushed onto the platform.

[0009] Furthermore, the platform is connected to the end of the guide rail via a loading slide, and a feeding channel is provided on the top surface of the platform at the corresponding notch. The extending direction of the feeding channel forms a 90-degree angle with the extending direction of the telescopic cylinder.

[0010] Through the above technical solution, in order to continuously feed materials, the feeding slide can be adjusted to move the platform downward and align it with the guide rail. The carrier tray containing the core will enter the feeding channel through the notch. After the core is removed, the push plate, driven by the feeding slide 26, moves along the feeding channel, which can push the carrier tray to move horizontally away from the curing mechanism and fall off the edge of the device. It can be collected for reuse. Then the push plate is reset and can continue to wait for the empty carrier tray to be pushed.

[0011] Furthermore, the three-degree-of-freedom horizontal moving stage includes a linear module one, a base plate is mounted on the free end of the linear module one, a linear module two is mounted on the lower part of the base plate, a linear module three is mounted on the free end of the linear module two, and a sliding base is mounted on the end of the linear module three.

[0012] The above technical solution discloses a specific configuration of a three-degree-of-freedom horizontal moving stage. Linear module one is horizontally installed and can drive the substrate to move horizontally left and right. Linear module two is installed at the bottom of the substrate and can drive linear module three to move up and down, so as to drive the pickup head and the spraying part to move back and forth along the height direction. Linear module three can be horizontally extended and retracted, but the extension and retraction direction is perpendicular to the movement direction of linear module one, so that the sliding base can move horizontally back and forth, so that the sliding base can approach and move away from the auxiliary mechanism and the curing mechanism for core transfer.

[0013] Furthermore, the spraying component includes a connecting frame, which is fixedly connected to the sliding base. A nozzle is installed at the bottom of the connecting frame, and a feed pipe is installed at the top of the nozzle. The pickup head includes a vertical pipe, an air distribution pipe is installed at the top of the vertical pipe, and an end sleeve is installed at the lower end of the vertical pipe. The end sleeve is slidably installed in the middle of the sliding base by a spring.

[0014] With the above technical solution, a pin is welded to each side of the core, and two spraying parts are designed. The welded sections of the pins are directly sprayed with paint from both sides. The supply pipe is connected to an external pumping device to continuously supply UV paint. The vertical tube is elastically installed with a spring, which can adaptively contract when in contact with the core. The vertical tube can slide upward to avoid excessive pressure causing core deformation. The air distribution pipe is connected to a negative pressure device to perform negative pressure suction on the core.

[0015] Furthermore, the bottom dimension of the connecting frame is larger than the top dimension of the accommodating cavity, the platform is connected to the moving plate through the feeding slide, the moving plate is provided with a suspended seat in the accommodating cavity, the vertical inner wall of the accommodating cavity is provided with a clearance groove that cooperates with the nozzle, and a waste collection shell is installed at the bottom of the accommodating cavity.

[0016] To prevent the sprayed UV paint from falling randomly in the air, the frame is placed over the top of the receiving cavity before spraying, blocking the opening at the top of the cavity. The nozzle is inserted into the receiving cavity and accommodated by the clearance groove, ensuring no gaps. The two nozzles spray paint on the connection between the two pins and the core from both sides. The core is pressed between the pickup head and the stand, so that the top and bottom surfaces of the core are blocked by the pickup head and the stand. The sprayed UV paint will fall downward through the stand and be collected by the waste collection shell.

[0017] Furthermore, the two-degree-of-freedom moving stage includes a lead screw slide, on which a vertical plate is mounted, and a second lead screw slide is mounted on the lower part of the vertical plate. A slide seat is mounted on the second lead screw slide, and the contact head is slidably mounted in the slide seat. An elastic element is provided between the slide seat and the contact head along the sliding direction of the slide seat, and the top of the contact head is connected to a negative pressure device through an air pipe.

[0018] The above technical solution discloses a specific configuration of a two-degree-of-freedom sliding stage. The first lead screw slide is arranged horizontally and drives the "T"-shaped support seat, so that the vertical plate will not interfere with the three-degree-of-freedom rotary sliding stage and the curing mechanism below when it moves horizontally. The second lead screw slide can drive the slide to slide up and down, so that the contact head can move up and down to pick up the core and move it away from the placement plate. The up and down displacement of the contact head can adjust the position of the impregnation clamp holding the support leg section, so that the support leg section is located as far as possible at the end of the impregnation clamp. Furthermore, the impregnation clamp is clamped as far away from the core as possible at the end of the support leg section, so that the impregnation clamp can be fully moved away from the impregnation agent during subsequent impregnation and the core can be fully inserted into the impregnation agent.

[0019] Furthermore, the three-degree-of-freedom rotary table includes a horizontal slide table, a crossbeam is mounted on the top of the horizontal slide table, a vertical slide table is mounted in the middle of the crossbeam, a middle frame is mounted on the free end of the vertical slide table, a rotary module is mounted on the end of the middle frame, and the rotary module is mounted on the circumferential side wall of the rotating shaft of the impregnation clamp.

[0020] The above technical solution discloses a specific configuration of a three-degree-of-freedom rotary transfer stage. The horizontal slide has two sections and a gantry frame as a base, which supports the cross frame and can drive the cross frame to slide horizontally. The vertical slide can drive the middle frame to slide along the height direction, so that the core can be inserted into or removed from the open material box. The rotary module is installed on the middle frame and can change the angle of the impregnation clamp, so that the core is inserted into the impregnating agent at an inclined angle. This can ensure that the core is fully inserted into the impregnating agent, but the end of the impregnating clamp will not be inserted into the impregnating agent, thus ensuring the cleanliness of the end of the impregnating clamp.

[0021] Furthermore, the impregnation clamp includes a movable clamp and a fixed clamp, a top spring is provided between the movable clamp and the fixed clamp, and the ends of the movable clamp and the fixed clamp are provided with a notch one and a notch two.

[0022] Through the above technical solution, in order to achieve stable clamping of the pins, the moving contact surface one of the moving clamp and the fixed contact surface one of the fixed clamp form a notch one, and the moving contact surface two of the moving clamp and the fixed contact surface two of the fixed clamp form a notch two. The distance between the fixed contact surface one and the fixed contact surface two is equal to the distance between the two pins. When clamping, the moving clamp is driven horizontally to approach the fixed clamp, compressing the top spring. The distance between the fixed contact surface one and the fixed contact surface two does not change. The moving contact surface one and the moving contact surface two will approach the fixed contact surface one and the fixed contact surface two respectively, completing the clamping action of the support segment. This can ensure that the distance between the two support segments remains unchanged, preventing the support segment from being broken or short-circuited due to relative displacement between the force and the core. After the negative pressure head picks up the core, the horizontal drive of the moving clamp disappears, and the top spring rebounds, causing the moving clamp to move away from the fixed clamp and relax the support segment.

[0023] Furthermore, the two-degree-of-freedom moving stage includes a driver, a mounting base is mounted on the top of the driver, a negative pressure head is mounted on the mounting base facing the immersion mechanism, a negative pressure pipe is mounted on the top of the negative pressure head, and the negative pressure pipe is connected to a negative pressure device.

[0024] The above technical solution discloses a specific configuration of a two-degree-of-freedom shift stage. The driver has an optical shaft with synchronous pulleys fixed at both ends. The optical shaft drives the synchronous belt to rotate through the synchronous pulleys. A mounting seat is fixed between the two synchronous belts, so that the mounting seat can slide horizontally close to the immersion mechanism, so that the workpiece on the immersion clamp can be transferred to the bottom of the negative pressure head. The operation of the negative pressure pipeline allows the negative pressure head to pick up the workpiece smoothly.

[0025] A method for using an integrated packaging device for dry film capacitors includes the following steps: S1. The top of the carrier plate accommodates multiple cores with welded pins. The stage descends to a position flush with the guide rail. The pusher extends to push the carrier plate through the notch to the top surface of the stage. The pusher shortens to allow the carrier plate filled with workpieces to be placed again. S2. The moving plate descends and presses the carrier plate onto the platform. The three-degree-of-freedom horizontal moving platform works, allowing the pickup head to directly contact the top surface of the core to complete the pickup and transport it into the receiving cavity. The spraying component sprays UV paint onto the connection between the core and the welding section. The pusher plate pushes the empty carrier plate away from the gap to make room for the subsequent carrier plate. S3. The three-degree-of-freedom horizontal moving stage works, allowing the pickup head to transfer the core to the placement slot of the placement plate. Sufficient distance is left between the vertical inner wall of the placement slot and the welding section to prevent the UV paint from sticking the welding section and the placement slot together. The chain conveyor drives the placement plate to quickly cure the UV paint through the curing lamp, so that a solid paint film is formed at the connection between the core and the welding section, completing the targeted reinforcement of the welding surface of the welding section and the core before impregnation. S4. The two-degree-of-freedom moving stage operates, allowing the contact head to directly contact the top surface of the core to complete the core pickup and transport it to the vertical impregnation clamp position. The impregnation clamp clamps the support segment of the needle. Driven by the three-degree-of-freedom rotating moving stage, the impregnation clamp tilts downward at a 45-degree angle, tilting and positioning the core and welding segment downward, and immersing them into the paste-like impregnating agent in the open material box. S5. The three-degree-of-freedom rotary table works, causing the impregnation clamp to lift the core and rotate it to a vertical position with the core facing upward. The impregnation agent on the outside of the impregnation clamp solidifies to form an outer layer. During the solidification process, the outer layer flows downward along the support leg section to form an extension that completely wraps the transition section. S6. The three-degree-of-freedom rotary stage rotates the core to a horizontal position. The two-degree-of-freedom stage operates, moving the negative pressure head directly above the core to capture the workpiece and transfer it to the receiving groove on the receiving component. The filled receiving component is then pushed horizontally along the guide table by the conveyor for unified collection. The empty receiving component is then added to wait for the next workpiece to be received.

[0026] The above technical solution reinforces the connection between the core and the welded section with UV paint before the clamped pins are impregnated with paint. This prevents the welded surface of the core from breaking due to external force during the subsequent impregnation of the core, thus avoiding short circuits caused by the impregnation process. Meanwhile, the impregnated core is placed vertically to allow the surface impregnating agent to solidify. During this process, the impregnating agent forms an extension in the transition section, increasing the contact area between the core and the pins and enhancing the connection strength between the pins and the core during later use.

[0027] The beneficial effects of this invention are as follows: This invention, through the setup of a feeding mechanism, an auxiliary mechanism, a first transverse movement mechanism, a curing mechanism, a second transverse movement mechanism, an impregnation mechanism, and a settling mechanism, allows the auxiliary mechanism to perform targeted paint reinforcement on the welding positions of the pins and the core during the impregnation and coating stage of the capacitor, before the equipment clamps the pins. This prevents short circuits caused by twisting due to the pins being clamped. During the curing process of the impregnating agent, the impregnation mechanism allows the impregnating agent to flow and coat the longer pins, ensuring the strength of the pins in later use. This invention optimizes the process flow by using UV paint to reinforce the connection between the core and the welded section before impregnating the clamped pins with paint. This prevents breakage between the welded surface of the core and the welded section due to external force during the subsequent core impregnation process, avoids short circuits caused by the impregnation process, and enhances the connection between the core and the pin by forming an extension in the transition section during the solidification process of the surface impregnating agent.

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0031] like Figure 1 - Figure 12 As shown, this embodiment provides an integrated packaging device for dry film capacitors. During the production of pin-type capacitors, the pins are flattened and then welded to both sides of the core 81 in order to weld them to the core 81. The welding points are relatively weak. Meanwhile, the pin support section 84 maintains its cylindrical shape, forming a transition section 83 with poor torsional resistance in the middle of the pin. Therefore, to specifically reinforce these weak points to adapt to immersion packaging and subsequent long-term use, a specific configuration is provided, including: The feeding mechanism 1 includes a horizontally arranged guide rail 12 with a flat top surface. A support plate 14 is movably provided in the middle of the guide rail 12. The support plate 14 can slide on the top surface of the guide rail 12. A pusher 11 is provided at the end of the guide rail 12 to provide a unidirectional driving force for the sliding of the support plate 14. The auxiliary mechanism 2 includes a platform 21. The platform 21 has a notch 211 at the end corresponding to the guide rail 12 that mates with the bearing plate 14. The width of the notch 211 is not less than the width of the bearing plate 14 so that the bearing plate 14 can pass smoothly. A movable plate 22 is installed on the platform 21 along the height direction. When the movable plate 22 moves down, it can press down on the edge of the bearing plate 14 to complete the positioning of the bearing plate 14. A receiving cavity 221 is opened in the middle of the movable plate 22. The receiving cavity 221 is staggered with the bearing plate 14. Specifically, the receiving cavity 221 is located between the extension of the movable plate 22 and the guide rail 12, and does not interfere with the bearing plate 14. The transverse mechanism 3 includes a three-degree-of-freedom horizontal moving stage. A pickup head 36 is installed at the free end of the three-degree-of-freedom horizontal moving stage. The pickup head 36 adopts a negative pressure suction pickup method. A spraying component 37 is coaxially provided on the outside of the pickup head 36. The spraying component 37 is used to seal the core 81 in the accommodating cavity 221 for targeted paint curing. The curing mechanism 4 includes a chain conveyor 41, which has a chain and two sprockets. A placement plate 42 with a placement groove 421 is installed on the outer circumference of the chain conveyor 41. As the chain rotates, the placement plate 42 can be continuously moved laterally and rotated back. A curing lamp 43 is provided directly above the placement plate 42. The curing lamp 43 emits ultraviolet light, which can accelerate the curing of UV paint 85. The second transverse mechanism 5 includes a two-degree-of-freedom moving stage 1, and a contact head 56 is installed at the free end of the two-degree-of-freedom moving stage 1. The contact head 56 adopts a negative pressure attraction pickup method. The impregnation mechanism 6 includes a three-degree-of-freedom rotary table. An impregnation clamp 65 is installed at the free end of the three-degree-of-freedom rotary table. The impregnation clamp 65 fixes the pins by mechanical clamping. An open material box 67 is provided below the impregnation clamp 65 to contain the paste impregnating agent so that the core 81 can be inserted for impregnation and coating. The open material box 67 is equipped with a heating device to prevent the impregnating agent in the open material box 67 from solidifying. A scraper 671 is provided at the position of the impregnating agent liquid surface in the open material box 67, which can be used to scrape and defoam after impregnation to prevent the foam on the surface of the impregnating agent from affecting the impregnation effect. The collection mechanism 7 includes a two-degree-of-freedom transfer stage 2. A negative pressure head 74 is installed at the free end of the two-degree-of-freedom transfer stage 2. After the impregnating agent is cured, the workpiece 8 is transferred by the negative pressure head 74 to the lower guide table 76. A conveyor 77 is embedded in the middle of the guide table 76. A receiving member 75 is slidably installed on the upper part of the guide table 76. The workpiece 8 is placed on the receiving member 75. The conveyor 77 is a belt with protrusions. When the belt is driven to rotate, the protrusions move laterally in the middle of the guide table 76, so that the receiving member 75 is horizontally pushed to the end of the belt and collected uniformly.

[0032] The working principle of this embodiment is as follows: First, refer to Figure 3 and Figure 4 The feeding mechanism 1 and the auxiliary mechanism 2 work together to place the carrier plate 14 containing the core 81 under the moving plate 22 and press it down. The transverse movement mechanism 3 works with the moving plate 22 to pick up the core 81 and spray UV paint 85. (Refer to...) Figure 6 The core 81 is conveyed by the curing mechanism 4 to the transverse movement mechanism 5. During the conveying process, the UV paint 85 will cure and fix the core 81 and the pins together, ensuring that the welding position will not crack and cause a short circuit when the pins are clamped and the core 81 is impregnated later. (Refer to...) Figure 7 and Figure 8 The transverse transfer mechanism 25 transfers the core 81 to the impregnation mechanism 6, as shown in the reference. Figure 9 Using the impregnation clamp 65 to hold the support leg section 84, immerse the core 81 and the welding section 82 in the impregnation agent, as per the instructions. Figure 11 The core 81 is placed vertically with the impregnating agent facing upwards until it cures into the outer layer 86. During the process, an extension 87 will also be formed, which increases the contact area between the cured outer layer 86 and the support segment 84, so that the transition segment 83 of the pin is completely wrapped when the part 8 is used in the later processing stage, making it less likely to twist or break.

[0033] In a further embodiment, to ensure the smooth pushing of the carrier disk 14, refer to Figure 3 The pusher 11 includes a telescopic cylinder, which adopts an electro-hydraulic actuator and can extend and retract horizontally. The end of the telescopic cylinder is provided with a straight plate, which is flush with the support plate 14. It can push the long strip support plate 14 to move along the guide rail 12. The straight plate is the same length as the support plate 14 and contacts the long side of the support plate 14. A baffle is provided at the edge of the guide rail 12 along the sliding direction of the straight plate. The end of the support plate 14 slides in contact with the vertical side wall of the baffle. Under the limitation of the baffle, the support plate 14 can be smoothly pushed onto the platform 21.

[0034] In a further embodiment, for continuous feeding, refer to Figure 3The platform 21 is connected to the end of the guide rail 12 via the loading slide 23. The top surface of the platform 21 is provided with a discharge channel at the corresponding notch 211. The loading slide 23 can adjust the platform 21 to descend and be flush with the guide rail 12. The carrier plate 14 containing the core 81 will enter the discharge channel through the notch 211. The extension direction of the discharge channel is at a 90-degree angle to the extension direction of the telescopic cylinder. After the core 81 is removed, the push plate 25 moves along the discharge channel under the drive of the loading slide 26, which can push the carrier plate 14 to move horizontally away from the curing mechanism 4 and fall off the edge of the device. It can be collected for reuse. After that, the push plate 25 is reset and can continue to wait for the empty carrier plate 14 to be pushed.

[0035] In a further embodiment, a specific configuration of a three-degree-of-freedom horizontal moving stage is disclosed, referring to... Figure 4 The three-degree-of-freedom horizontal moving stage includes a linear module 31, which is horizontally mounted and can drive the substrate 32 to move horizontally left and right. The substrate 32 is mounted on the free end of the linear module 31. A linear module 33 is mounted on the lower part of the substrate 32. A linear module 34 is mounted on the free end of the linear module 33, which can drive the linear module 34 to move up and down, so as to drive the pickup head 36 and the spraying part 37 to move back and forth along the height direction. A sliding seat is mounted on the end of the linear module 34. The linear module 34 can be horizontally extended and retracted, but the extension and retraction direction is perpendicular to the movement direction of the linear module 31, so that the sliding seat can move horizontally back and forth, so that the sliding seat can approach and move away from the auxiliary mechanism 2 and the curing mechanism 4 for the transfer of the core 81.

[0036] In a further embodiment, the specific configuration of the pickup head 36 and the spraying component 37 is disclosed. The spraying component 37 includes a connecting frame 373, which is fixedly connected to the sliding base. A nozzle 372 is installed at the bottom of the connecting frame 373, and a feed pipe 371 is installed at the top of the nozzle 372. Because a pin is welded to each side of the core 81, the spraying component 37 is also designed with two pins, and the welded sections 82 of the pins are directly sprayed with paint through both sides. The feed pipe 371 is additionally connected to an external pumping device to hold the UV paint 85. Continuing supply, the pickup head 36 includes a vertical tube 361, with an air distribution pipe 35 installed at the top of the vertical tube 361 and an end sleeve 363 installed at the lower end of the vertical tube 361. The end sleeve 363 is slidably installed in the middle of the sliding seat by a spring 362, while the vertical tube 361 is elastically installed by the spring 362, which can adaptively contract when contacting the core 81. The vertical tube 361 can slide upward to avoid excessive pressure causing deformation of the core 81. The air distribution pipe 35 is connected to a negative pressure device to perform negative pressure suction of the core 81.

[0037] In a further embodiment, to prevent the sprayed UV paint 85 from falling randomly in the air, refer to Figure 5The bottom dimension of the connecting frame 373 is larger than the top dimension of the receiving cavity 221. Before painting, the connecting frame 373 covers the top of the receiving cavity 221, blocking the top opening of the receiving cavity 221. The platform 21 is connected to the moving plate 22 via the second loading slide 24. The moving plate 22 has a support 224 in the receiving cavity 221. The vertical inner wall of the receiving cavity 221 has a relief groove 223 that mates with the nozzle 372. The nozzle 372 is inserted into the receiving cavity 221 and is protected by the relief groove 223. The groove 223 is used to accommodate the core 81 and ensure there are no gaps. Two nozzles 372 spray paint on the connection between the two pins and the core 81 from both sides. The core 81 is pressed between the pickup head 36 and the support 224, so that the top and bottom surfaces of the core 81 are blocked by the pickup head 36 and the support 224. A waste collection shell 222 is installed at the bottom of the accommodating cavity 221. The sprayed UV paint 85 will fall downward through the position of the support 224 and be collected by the waste collection shell 222.

[0038] In a further embodiment, a specific configuration of a two-degree-of-freedom shift stage is disclosed, referring to... Figure 7 and Figure 8 The two-degree-of-freedom moving stage includes a lead screw slide 52, which is horizontally arranged and drives a "T"-shaped support. A vertical plate 51 is mounted on the lead screw slide 52 to prevent interference with the three-degree-of-freedom rotary moving stage and the curing mechanism 4 below when the vertical plate 51 moves horizontally. A second lead screw slide 53 is mounted on the lower part of the vertical plate 51, which can drive the slide 55 to slide up and down, so that the contact head 56 can move up and down to pick up the core 81 and move it away from the placement plate 42. The slide 55 is mounted on the second lead screw slide 53, and the contact head 56 is slidably mounted in the slide 55. The displacement can adjust the position of the impregnation clamp 65 holding the support leg section 84, so that the support leg section 84 is located as far as possible at the end of the impregnation clamp 65, and the impregnation clamp 65 is clamped as far away from the end of the support leg section 84 as possible, so that the impregnation clamp 65 can be fully away from the impregnating agent during subsequent impregnation and the core 81 can be fully inserted into the impregnating agent. An elastic element is provided between the slide 55 and the contact head 56 along the sliding direction of the slide 55. The contact head 56 can be pressed upward when contacting the core 81 to avoid damaging the core 81. The top of the contact head 56 is connected to a negative pressure device through the air pipe 54 to provide negative pressure suction to smoothly pick up the core 81.

[0039] In a further embodiment, a specific configuration of a three-degree-of-freedom rotary table is disclosed, referring to... Figure 8 and Figure 9The three-degree-of-freedom rotary table includes two horizontal slides 61 with a gantry frame as a base. A crossbeam 62 is mounted on the top of the horizontal slides 61, which can be driven to slide horizontally. A vertical slide 63 is mounted in the middle of the crossbeam 62. The vertical slide 63 can drive the middle frame 64 to slide along the height direction, so that the core 81 can be inserted into or removed from the open material box 67. The middle frame 64 is mounted on the free end of the vertical slide 63. A rotating module 68 is mounted on the end of the middle frame 64. The rotating module 68 is mounted on the circumferential side wall of the impregnation clamp 65. It can change the angle of the impregnation clamp 65 so that the core 81 is inserted into the impregnating agent at an inclined angle. This ensures that the core 81 is fully inserted into the impregnating agent, but the end of the impregnation clamp 65 is not inserted into the impregnating agent, thus ensuring the cleanliness of the end of the impregnation clamp 65.

[0040] In a further embodiment, to achieve stable clamping of the pins, refer to Figure 10 and Figure 11 The impregnation clamp 65 includes a movable clamp 651 and a fixed clamp 652. A notch 654 is formed by the movable contact surface 656 of the movable clamp 651 and the fixed contact surface 657 of the fixed clamp 652. A notch 655 is formed by the movable contact surface 658 of the movable clamp 651 and the fixed contact surface 659 of the fixed clamp 652. The distance between the fixed contact surfaces 657 and 659 is equal to the distance between two pins. During clamping, the movable clamp 651 is horizontally driven closer to the fixed clamp 652. An electromagnet can be used as the power source for this horizontal drive. The electromagnet is installed on one side of the fixed clamp 652 and, when energized, can attract the movable clamp 651 closer to the fixed clamp 652. A top spring 653 is provided between 52. After the top spring 653 is compressed, the distance between the fixed contact surface 657 and the fixed contact surface 659 will not change. The moving contact surface 656 and the moving contact surface 658 will approach the fixed contact surface 657 and the fixed contact surface 659 respectively, completing the clamping action of the support leg section 84. This ensures that the distance between the two support leg sections 84 remains unchanged, preventing the support leg section 84 from being broken or short-circuited due to relative displacement between the force and the core 81. After the negative pressure head 74 picks up the core 81, the electromagnet is de-energized, the moving clamp 651 is horizontally driven away, and the top spring 653 rebounds, causing the moving clamp 651 to move away from the fixed clamp 652 and release the support leg section 84.

[0041] In a further embodiment, a specific configuration of a two-degree-of-freedom shift stage is disclosed, referring to... Figure 12The two-degree-of-freedom moving stage includes a driver 71. The driver 71 has an optical shaft with synchronous pulleys fixed at both ends and is connected to the driver for rotational drive. The optical shaft drives the synchronous belt to rotate through the synchronous pulleys. A mounting base 72 is installed on the top of the driver 71. The mounting base 72 is fixed between two synchronous belts, so that the mounting base 72 can slide horizontally close to the impregnation mechanism 6. A negative pressure head 74 is installed on the side of the mounting base 72 facing the impregnation mechanism 6. A negative pressure pipe 73 is installed on the top of the negative pressure head 74. The negative pressure pipe 73 is connected to the negative pressure equipment so that the workpiece 8 on the impregnation clamp 65 can be transferred to the bottom of the negative pressure head 74. The operation of the negative pressure pipe 73 allows the negative pressure head 74 to pick up the workpiece 8 smoothly.

[0042] A method for using an integrated packaging device for dry film capacitors includes the following steps: S1. The top of the carrier plate 14 accommodates multiple cores 81 with welded pins. The platform 21 is driven down by the loading slide 23 to a position flush with the guide rail 12. The pusher 11 extends to push the carrier plate 14 through the notch 211 to the top surface of the platform 21. The pusher 11 shortens and resets so that the carrier plate 14 filled with the workpiece 8 can be placed again. S2. The feeding slide 24 causes the moving plate 22 to descend, pressing the carrier plate 14 onto the carrier 21 from top to bottom. The three-degree-of-freedom horizontal moving table works, so that the pickup head 36 directly contacts the top surface of the core 81 from top to bottom. The negative pressure device evacuates the inside of the end sleeve 363 to suck up the core 81 and completes the pickup and transport to the receiving cavity 221. The spraying part 37 sprays UV paint 85 at the connection between the core 81 and the welding section 82. The pickup head 36 moves upward and will take the core 81 away from the carrier plate 14. The push plate 25 pushes the empty carrier plate 14 away from the notch 211 to make room for the subsequent carrier plate 14. S3. The three-degree-of-freedom horizontal moving table operates, allowing the pickup head 36 to transfer the core 81 to the placement slot 421 of the placement plate 42. The pickup head 36 is inflated to eliminate the negative pressure state, so that after the pickup head 36 is reset, the core 81 remains in the placement slot 421. Sufficient distance is left between the vertical inner wall of the placement slot 421 and the welding section 82 to prevent the UV paint 85 from sticking the welding section 82 and the placement slot 421 together. The chain conveyor 41 is in the shape of a ring and multiple placement plates 42 are installed on its outer wall. The chain conveyor 41 drives the placement plate 42 filled with cores 81 to move, and moves an empty placement plate 42 to the material feeding position of the pickup head 36. The core 81 above the placement plate 42 will be baked by the curing lamp 43, so that the UV paint 85 is cured quickly, and a solid paint film is formed at the connection between the core 81 and the welding section 82, completing the targeted reinforcement of the welding surface of the welding section 82 and the core 81 before impregnation. S4. The two-degree-of-freedom moving stage operates, causing the contact head 56 to contact the top surface of the core 81 from top to bottom. The contact head 56 is evacuated by the negative pressure device, completing the picking up of the core 81 and transporting it to the vertical position of the impregnation clamp 65. The impregnation clamp 65 clamps the support leg section 84 of the needle vertically upward. Driven by the three-degree-of-freedom rotating moving stage, the impregnation clamp 65 is tilted downward at a 45-degree angle, positioning the core 81 and the welding section 82 downward at an angle, and immersing them in the paste-like impregnating agent in the open material box 67, so that the surface of the core 81 is covered with a paint film. S5. The three-degree-of-freedom rotary table works, causing the impregnation clamp 65 to lift the core 81 and rotate it to a vertical position with the core 81 facing upward. The impregnation agent on the outside of the impregnation clamp 65 is cured to form an outer layer 86. During the curing process, the outer layer 86 flows downward along the support leg section 84 to form an extension 87 that completely wraps the transition section 83. After curing, the weak points of the pin are reinforced. S6. The three-degree-of-freedom rotary stage rotates the core 81 to a horizontal position. The two-degree-of-freedom rotary stage operates, moving the negative pressure head 74 from top to bottom to directly contact the outer layer 86 above the core 81. The negative pressure device evacuates the negative pressure head 74, capturing the workpiece 8. The workpiece 8 is transferred to the receiving groove on the receiving component 75. The filled receiving component 75 is horizontally pushed by the conveyor 77 along the guide table 76 for unified collection. After the conveyor 77 is translated and reset, the empty receiving component 75 is replenished to wait for the workpiece 8 to be collected again.

[0043] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention.
