Description

Technical Field

[0001] This application relates to the field of capacitor manufacturing technology, and in particular to a spin-drying clamping device. Background Technology

[0002] In the automated production process of capacitors, the impregnated capacitor elements need to be dehydrated. This dehydration process requires a spin-drying clamping device to hold the capacitor elements. In related technologies, spin-drying clamping devices typically use cam bearings moving within cam slots to bring coaxial connecting rods together or separate, thus opening and closing the clamping units. While this structure achieves automatic opening and closing, switching between elements of different diameters requires manual adjustment of the first positive and negative thread screws to rotate, causing two gears to mesh and drive the second positive and negative thread screws to rotate. This adjusts the spacing of the clamping units to accommodate elements of different diameters. This design is complex and cumbersome to operate.

[0003] It should be noted that the information disclosed in the above background section is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0005] This application provides a spin-drying clamping device for use in a spin-drying drum, the device comprising:

[0006] A rotating base is rotatably mounted inside the spin dryer drum.

[0007] Four clamping mechanisms are evenly distributed on the rotating base and rotatably connected to the rotating base. Each clamping mechanism includes: a base plate, a driven gear, a forward and reverse threaded rod, a first threaded rod nut, a second threaded rod nut, a first clamping assembly, and a second clamping assembly. One end of the base plate is rotatably connected to the rotating base. The forward and reverse threaded rods are rotatably disposed in the bottom.

[0033] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0034] like Figures 1 to 6 As shown in the figure, this application provides a spin-drying clamping device for use in a spin-drying drum. The device includes a rotating base 100, a clamping mechanism 200, a driving mechanism 300, and a lifting mechanism 400. The device drives a driven gear via the driving mechanism 300, causing the forward and reverse threaded rods 220 to rotate. The first clamping assembly 250 and the second clamping assembly 260 can then move towards or away from each other, thereby clamping and releasing capacitor elements. Simultaneously, the driving mechanism 300 can adjust the gap between the first clamping assembly 250 and the second clamping assembly 260 to clamp capacitor elements of different sizes.

[0035] The following is a detailed description of the structure of the spin-drying clamping device.

[0036] The rotating base 100 is rotatably mounted inside the spin dryer. The rotating base 100 can rotate 90° at a time to facilitate the engagement of the lifting mechanism 400 with different clamping mechanisms 200.

[0037] Four clamping mechanisms 200 are evenly distributed on the rotating base 100 and rotatably connected to it. By setting multiple clamping mechanisms 200, the number of capacitor elements clamped during the spin-drying step is increased, effectively improving the spin-drying efficiency of the capacitor elements. Each clamping mechanism 200 can be rotatably connected to the rotating base 100. During the spin-drying step, all four clamping mechanisms 200 are located in an inclined state in the spin-drying drum. When it is necessary to load or unload capacitor elements, the lifting mechanism 400 can drive the two opposing clamping mechanisms 200 to a horizontal state, thereby facilitating the loading and unloading of capacitor elements.

[0038] Specifically, the clamping mechanism 200 may include: a base plate 210, a driven gear 280, a forward and reverse threaded screw 220, a first threaded screw nut 230, a second threaded screw nut 240, a first clamping assembly 250, and a second clamping assembly 260. One end of the base plate 210 is rotatably connected to the rotating base 100. The forward and reverse threaded screw 220 is rotatably disposed in the bottom. The driven gear 280 is sleeved on the forward and reverse threaded screw 220. The first threaded screw nut 230 is drivenly connected to the forward tapping part of the forward and reverse threaded screw 220. The first clamping assembly 250 is connected to the first threaded screw nut 230. The second threaded screw nut 240 is drivenly connected to the reverse tapping part of the forward and reverse threaded screw 220. The second clamping assembly 260 is connected to the second threaded screw nut 240.

[0039] When the clamping mechanism 200 is in a horizontal state, it is driven to connect with the drive mechanism 300. The drive mechanism 300 drives the driven gear 280 to rotate, causing the lead screw 220 to rotate. The first lead screw nut 230 and the second lead screw nut 240 move towards or away from each other along the length of the lead screw 220. At this time, the first clamping assembly 250 and the second clamping assembly 260 can move towards or away from each other, thereby adjusting the clamping distance between the first clamping assembly 250 and the second clamping assembly 260.

[0040] The drive mechanism 300 is located on the outside of the spin dryer body and meshes with the driven gear 280. It is used to drive the forward and reverse threaded rods 220 to rotate, so that the first clamping assembly 250 and the second clamping assembly 260 can move towards each other or away from each other.

[0041] The lifting mechanism 400 is movably mounted on the rotating base 100. The lifting mechanism 400 is used to drive the two opposing clamping mechanisms 200 to a horizontal state.

[0042] In practical applications, during capacitor element loading, the rotating base 100 rotates, positioning the lifting mechanism 400 below the two opposing clamping mechanisms 200. The lifting mechanism 400 moves upward and slides into contact with the two opposing clamping mechanisms 200, changing their tilted state to a horizontal state. At this point, the two clamping mechanisms 200 are connected to the drive mechanism 300. The drive mechanism 300 operates, enabling the first clamping assembly 250 and the second clamping assembly 260 to move in opposite directions, placing the capacitor element on the base plate 210 between the first clamping assembly 250 and the second clamping assembly 260. The drive mechanism 300 then reverses its operation, causing the first clamping assembly 250 and the second clamping assembly 260 to move towards each other, thus clamping the capacitor element. The lifting mechanism 400 moves downward and slides into contact with the two opposing clamping mechanisms 200, returning them to their initial state. The rotating base 100 is rotated 90° so that the lifting mechanism 400 is located below the other two opposing clamping mechanisms 200, and the above feeding process is repeated.

[0043] Since the process of loading and unloading capacitor elements is the same, it will not be described in detail here.

[0044] like Figures 1 to 6 As shown, in some embodiments, the clamping mechanism 200 further includes a pulley assembly 270, which is disposed on the side of the base plate 210 away from the rotating base 100, and is used to slide with the lifting mechanism 400. Through the sliding connection between the pulley assembly 270 and the lifting mechanism 400, the clamping mechanism 200 can change from an inclined state to a horizontal state, enabling the capacitor elements to be loaded and unloaded from the clamping mechanism 200.

[0045] like Figures 1 to 6 As shown, in some embodiments, the first clamping assembly 250 includes: a first clamping block 251 and a first connecting rod 252. There are two first connecting rods 252, which are arranged side by side in the base plate 210. The two first connecting rods 252 are located on both sides of the positive and negative threaded screw 220. There are three first clamping blocks 251, which are spaced apart on the first connecting rods 252. One first clamping block 251 is connected to the first threaded screw nut 230.

[0046] The three first clamping blocks 251 are connected by the first connecting rod 252, which effectively simplifies the structure of the first clamping assembly 250 and avoids the clamping mechanism 200 from being too complex. By connecting one of the first clamping blocks 251 to the first lead screw nut 230, the three first clamping blocks 251 can be controlled to move synchronously, realizing the automated movement of the first clamping assembly 250.

[0047] like Figures 1 to 6As shown, in some embodiments, the second clamping assembly 260 includes: a second clamping block 261 and a second connecting rod 262. There are two second connecting rods 262, which are arranged side by side in the base plate 210. The two second connecting rods 262 are located on both sides of the positive and negative threaded screw 220. There are three second clamping blocks 261, which are spaced apart on the second connecting rods 262. One second clamping block 261 is connected to the second threaded screw nut 240.

[0048] The three second clamping blocks 261 are connected by the second connecting rod 262, which effectively simplifies the structure of the second clamping assembly 260 and avoids the clamping mechanism 200 from being too complex. By connecting one of the second clamping blocks 261 to the second lead screw nut 240, the three second clamping blocks 261 can be controlled to move synchronously, realizing the automated movement of the second clamping assembly 260.

[0049] like Figures 1 to 6 As shown, in some embodiments, the drive mechanism 300 includes: a mounting base 310, a buffer assembly 320, a fixed plate 330, a drive motor 340, a drive gear 350, and a transmission gear 360. The mounting base 310 is disposed on the spin-drying drum body. The fixed plate 330 is slidably connected to the mounting base 310 through the buffer assembly 320. The drive motor 340 is disposed on the fixed plate 330, and the output end of the drive motor 340 meshes with the drive gear 350. The transmission gear 360 is rotatably disposed on the fixed plate 330 and meshes with the drive gear 350. When the clamping mechanism 200 is in a horizontal state, the transmission gear 360 meshes with the driven gear 280.

[0050] During the meshing process of the drive gear 360 and the driven gear 280, the buffer assembly 320 helps to reduce and disperse the vibration caused by meshing, thereby improving the stability and durability of the drive mechanism 300.

[0051] like Figures 1 to 6 As shown, in some embodiments, the buffer assembly 320 includes a first screw 321, a second screw 322, and a tension spring 323. The first screw 321 is disposed on the fixing plate 330, the second screw 322 is disposed on the mounting base 310, and the tension spring 323 is disposed between the first screw 321 and the second screw 322.

[0052] like Figures 1 to 6 As shown, in some embodiments, the lifting mechanism 400 includes a lifting cylinder, a lifting rod 410, and a lifting seat 420. The lifting cylinder is located on one side of the spin dryer body and is coaxially connected to the lifting rod 410. The lifting seat 420 is located on the lifting rod 410 and has a sliding surface. The clamping mechanism 200 is slidably engaged with the sliding surface.
