Description

Technical Field

[0001] This utility model relates to the field of mica capacitor welding, and in particular to a mica capacitor electrode welding positioning device. Background Technology

[0002] Mica capacitors are capacitors that use mica as the dielectric. They have high stability, low loss and excellent temperature characteristics. Their structure is usually made of alternating layers of metal foil electrodes and mica sheets. They are suitable for high-frequency circuits, filters and precision electronic equipment. Mica capacitors are often welded to the surface of the electrode plate by zinc strips at the bottom.

[0003] Welding mica capacitors is mostly done through backplate welding. During the welding process, it is necessary to ensure the stability of the capacitor while welding in reverse. The welding space is also small, making the welding work extremely inconvenient. At the same time, when placing the mica capacitor, the electrode plate needs to maintain a certain stability. The electrode plate itself is relatively fragile, and physical clamps may cause damage to the sides of the electrode plate due to excessive clamping force. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mica capacitor electrode welding and positioning device that improves the convenience of welding mica capacitors to electrode plates and avoids damage to electrode plates caused by excessive clamping force of physical clamps.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A mica capacitor electrode welding and positioning device includes a bottom support plate for bottom support. A support placement seat is fixedly connected to the top center of the bottom support plate. An installation frame is slidably connected to the outer side of the support placement seat. An electric push rod is fixedly connected to the top inner side of the installation frame. A lower pressure plate is fixedly connected to the output end of the electric push rod. A soft rubber limiting pad is fixedly connected to the bottom end of the lower pressure plate. A positioning frame is attached to the top of the support placement seat. Connecting plates are fixedly connected to both sides of the positioning frame. The outer sides of the connecting plates are respectively fixedly connected to the inner sides of the installation frame. The outer side of the installation frame is connected to the top of the bottom support plate through a traction lifting component to facilitate welding of the electrode plate to the mica capacitor. An adsorption fixing component is installed inside the support placement seat to fix the electrode plate.

[0007] Furthermore, the adsorption and fixing assembly includes an exhaust hood located inside the support placement seat, a perforated plate is fixedly connected inside the exhaust hood, an air pump is fixedly connected to the middle of the front end of the support placement seat, an air extraction pipe is fixedly connected to the bottom end of the exhaust hood, and the front end of the air extraction pipe is fixedly connected to the input end of the air pump.

[0008] Furthermore, the traction lifting assembly includes a fixed seat located at the rear of the top of the bottom support plate. A rotating rod is rotatably connected inside the fixed seat, and a take-up roller is fixedly connected outside the rotating rod. Traction ropes are fixedly connected to both sides of the take-up roller, and right-angle pull rods are fixedly connected to the outer sides of the traction ropes. A flipping plate is rotatably connected to the inner side of the right-angle pull rod, and the top of the flipping plate is rotatably connected to the bottom of the mounting frame.

[0009] Furthermore, a drive motor is fixedly connected to the rear end of the fixed base, and the drive end of the drive motor is fixedly connected to the rear end of the rotating rod.

[0010] Furthermore, support limiting plates are fixedly connected to both sides of the top of the positioning frame to achieve positioning of the lower pressure plate pressing down.

[0011] Furthermore, limit rods are fixedly connected to both sides of the top of the lower pressure plate, and the outer sides of the limit rods are respectively slidably connected to the top of the mounting frame.

[0012] Furthermore, a sealing frame is fixedly connected to the bottom end of the positioning frame, and a sealing groove is opened at the top end of the support placement seat. A sealing gasket is fixedly connected to the bottom end of the inner part of the sealing groove, and the outer part of the sealing frame is nested inside the sealing groove.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, by pressing down with the lower pressure plate, the soft rubber limiting pad adheres to the outside of the mica capacitor, thereby limiting the mica capacitor and the electrode plate. Then, by winding up with the take-up roller, the right-angle tie rods on both sides are pulled inward at the same time, thereby raising the mounting frame, thereby expanding the welding space and improving the convenience of welding the mica capacitor and the electrode plate.

[0015] 2. In this utility model, the suction pump generates an outward suction force on the suction pipe, creating a negative pressure environment inside the suction hood. This allows the electrode plate to be adsorbed and fixed through the multiple slots of the perforated plate, avoiding damage to the electrode plate caused by excessive clamping force from the physical clamps, ensuring the integrity of the electrode plate welding, and reducing cost losses.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-3 This utility model provides an embodiment of a mica capacitor electrode welding and positioning device, comprising a bottom support plate 1 for bottom support, a support placement seat 2 fixedly connected to the top center of the bottom support plate 1, a mounting frame 8 slidably connected to the outer side of the support placement seat 2, an electric push rod 6 fixedly connected to the top inner side of the mounting frame 8, a lower pressure plate 16 fixedly connected to the output end of the electric push rod 6, a soft rubber limiting pad 17 fixedly connected to the bottom end of the lower pressure plate 16, and a positioning frame 4 abutting the top of the support placement seat 2. (Refer to...) Figure 4Both sides of the positioning frame 4 are fixedly connected to connecting plates 18. The outer sides of the connecting plates 18 are respectively fixedly connected to the inner sides of the mounting frame 8. The outer side of the mounting frame 8 is connected to the top of the bottom support plate 1 through a traction lifting assembly to facilitate the welding of the electrode plate to the mica capacitor. The support placement seat 2 is equipped with an adsorption fixing assembly to fix the electrode plate. The traction lifting assembly includes a fixing seat 12 located at the rear of the top of the bottom support plate 1. A rotating rod 14 is rotatably connected inside the fixing seat 12. A winding roller 11 is fixedly connected to the outside of the rotating rod 14. Both sides of the winding roller 11 are fixedly connected to... There is a traction rope 15, and right-angle pull rods 9 are fixedly connected to the outer side of the traction rope 15. A flip plate 10 is rotatably connected to the inner side of the right-angle pull rod 9. The top of the flip plate 10 is rotatably connected to the bottom of the mounting frame 8. A drive motor 13 is fixedly connected to the rear end of the fixed seat 12. The drive end of the drive motor 13 is fixedly connected to the rear end of the rotating rod 14. Support limiting plates 5 are fixedly connected to both sides of the top of the positioning frame 4 to realize the positioning of the lower pressure plate 16 pressing down. Limiting rods 7 are fixedly connected to both sides of the top of the lower pressure plate 16. The outer side of the limiting rods 7 is slidably connected to both sides of the top of the mounting frame 8.

[0025] During the welding process of the electrode plate backplate, the electric push rod 6 is first activated to push the lower pressure plate 16 downward until its bottom end contacts the top of the support limiting plate 5. At this time, the soft rubber limiting pad 17 is tightly attached to the surface of the mica capacitor to form a wrap to enhance stability. Subsequently, the drive motor 13 is started, driving the rotating rod 14 to rotate, which in turn causes the winding roller 11 to rotate, tightening the traction rope 15, applying an inward pulling force to the right-angle pull rods 9 on both sides, and pushing the flipping plate 10 to flip. The flipping action of the flipping plate 10 lifts the mounting frame 8 upward, and the positioning frame 4 is lifted synchronously through the connecting plate 18, so that the bottom of the electrode plate is completely exposed, thereby providing sufficient operating space for the backplate welding, significantly improving the convenience and efficiency of welding the mica capacitor and the electrode plate.

[0026] Reference Figure 2 , Figure 4 and Figure 5 The adsorption and fixing assembly includes an exhaust hood 21 located inside the support placement seat 2. A perforated plate 22 is fixedly connected inside the exhaust hood 21. An air pump 3 is fixedly connected to the middle of the front end of the support placement seat 2. An exhaust pipe 20 is fixedly connected to the bottom end of the exhaust hood 21. The front end of the exhaust pipe 20 is fixedly connected to the input end of the air pump 3. A sealing frame 19 is fixedly connected to the bottom end of the positioning frame 4. A sealing groove 23 is opened at the top end of the support placement seat 2. A sealing gasket 24 is fixedly connected to the bottom end of the sealing groove 23. The outer part of the sealing frame 19 is nested inside the sealing groove 23.

[0027] The electrode plate to be welded is placed in the inner slot of the positioning frame 4. Soft pads are evenly laid in the slot to provide cushioning and sealing. Then, the air pump 3 is started, and the air in the exhaust hood 21 is discharged outward through the exhaust pipe 20. At the same time, multiple holes on the perforated plate 22 generate a uniformly distributed suction force downward, which firmly attracts and fixes the bottom of the electrode plate. Next, the mica capacitors are inserted one by one into the reserved holes on the surface of the electrode plate. The suction force keeps the mica capacitors stable during installation, avoiding the electrode plate damage that may be caused by excessive clamping force in traditional physical clamps. This design not only ensures the integrity of the electrode plate during welding, but also reduces cost losses caused by damage and improves welding efficiency and quality.

[0028] Working principle: The electrode plate to be welded is placed in the inner slot of the positioning frame 4. The inner slot of the positioning frame 4 is evenly sealed with soft pads. At this time, the air pump 3 is started, and the air inside the exhaust hood 21 is discharged to the outside through the air extraction pipe 20. At the same time, suction force is generated downward through multiple holes in the perforated plate 22. The suction force generated by multiple holes is evenly distributed at the bottom of the electrode plate, thereby fixing the electrode plate. Then, mica capacitors are inserted into the pre-drilled holes on the surface of the electrode plate. As the suction force is generated, the inserted mica capacitors are simultaneously stabilized. When welding the back plate of the electrode plate, the electric push rod 6 is started to push the lower... The pressure plate 16 is pushed downwards until its bottom end contacts the top of the support limiting plate 5. The soft rubber limiting pad 17 contacts the surface of the mica capacitor, wrapping it to a certain extent to ensure its stability. At this time, the drive motor 13 is started to rotate the rotating rod 14, thereby rotating the winding roller 11 and winding the traction rope 15. This generates an inward pulling force on the right-angle pull rods 9 on both sides and a pushing force on the flipping plate 10. The flipping plate 10 flips, thereby lifting the mounting frame 8 upwards. The positioning frame 4 is simultaneously lifted upwards through the connecting plate 18, exposing the bottom of the electrode plate for backplate welding.
