Description

Technical Field

[0001] The utility model relates to the technical field of capacitor production and processing, in particular to a hot pressing device for film capacitors. Background Art

[0002] Film capacitors use metal foil as electrodes, which are overlapped with plastic films such as polyethylene, polypropylene, polystyrene or polycarbonate at both ends and then wound into a cylindrical structure to form capacitors. Film capacitors need to undergo a hot pressing process during processing to make the core structure of the film capacitor more stable and the capacitance more stable. When hot pressing film capacitors, hot pressing equipment is required. The existing hot pressing equipment requires manual removal of the film capacitors in the hot pressing equipment after the previous batch of film capacitors in the hot pressing equipment is completed, and then another batch of film capacitors is loaded and repeated during heating and pressing. As a result, when hot pressing film capacitors, manual removal is required to continuously remove the film capacitors from the hot pressing equipment. Since the temperature of the film capacitors is high after hot pressing, if the film capacitors are not taken out in time, their internal structure is easily damaged, affecting the production effect of the film capacitors. At the same time, the internal temperature of the hot pressing equipment is excessively wasted during the removal process, increasing the energy consumption of the equipment. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1

[0027] In order to solve the problem of tedious operation during processing of film capacitors and damage to their internal structure due to slow handling speed, please refer to Figure 1-Figure 5This embodiment provides a hot pressing device for film capacitors. After hot pressing, the cooling assembly 28 in the processing assembly 2 can promptly cool the film capacitors, preventing damage to their internal structure due to slow handling, thereby improving the production efficiency of film capacitors. The device includes a base 1 located within a processing area, which is used to support the processing assembly 2 and the conveying assembly 3. The base 1 is provided with the processing assembly 2 for processing the film capacitors, and the conveying assembly 3 for transporting the film capacitors. The conveying assembly 3 is provided with a loading plate 4 for holding the film capacitors. Before hot pressing the film capacitor, the loading plate 4 is installed on the conveying component 3, and then the film capacitor is loaded into the loading plate 4, and the film capacitor is conveyed to the processing component 2 for hot pressing by the conveying component 3. After the hot pressing is completed, the film capacitor is cooled by the processing component 2, and then conveyed out of the processing component 2 by the conveying component 3 for collection, thereby simplifying the tedious operation during the hot pressing of the film capacitor, avoiding damage to the internal structure of the film capacitor due to slow picking speed, and thus improving the work efficiency and production quality of the film capacitor.

[0028] The processing assembly 2 includes a processing chamber 21 fixedly mounted on the base 1. The processing chamber 21 is open at both ends and forms a hot pressing space inside, which is convenient for hot pressing of film capacitors therein. A cover plate 22 is fixedly connected to the processing chamber 21, and an inner cavity 23 is provided in the cover plate 22. Heating shafts 24 are symmetrically provided on the inner wall of the processing chamber 21. The heating shafts 24 are used to heat the interior of the processing chamber 21 so that the internal temperature reaches the temperature required for hot pressing of film capacitors to ensure the hot pressing effect. The heating can be done by electric heating or other heating methods. A pressing block 25 for hot pressing film capacitors is slidably connected to the processing chamber 21. The size of the pressing block 25 is compatible with the loading plate 4. A cylinder 26 is fixedly mounted on the cover plate 22 to drive the pressing block 25 to move vertically. The cylinder 26 serves as the power source for pressing the film capacitors. The processing chamber 21 is provided with an opening and closing assembly 27 for sealing or opening the hot pressing space. The processing chamber 21 is also provided with a cooling assembly 28 for dissipating heat from the film capacitors after hot pressing. The cooling assembly 28 includes an air outlet 281 provided on the top of the inner wall of the processing chamber 21. The air outlet 281 is connected to a fan 282 fixedly mounted on the cover plate 22. The fan 282 serves as a power source for air cooling the film capacitor. When the film capacitor is loaded into the loading plate 4, the film capacitor is transported into the processing chamber 21 with the cooperation of the opening and closing assembly 27 and the conveying assembly 3. The opening and closing assembly 27 then closes the processing chamber 21 and heats it via the heating shaft 24 to the desired hot pressing temperature. The cylinder 26 is then activated, and the pressing block 25 is moved vertically to the surface of the loading plate 4 under the action of the cylinder 26. The film capacitor is hot pressed by the cylinder 26 and the pressing block 25. After the hot pressing is completed, the film capacitor is transported to the cooling assembly 28 with the cooperation of the opening and closing assembly 27 and the conveying assembly 3. Subsequently, the fan 282 is started, and the film capacitors in the processing chamber 21 are cooled by air through the air outlet 281. After cooling, the film capacitors are transported out of the processing chamber 21 through the conveyor assembly 3, and the film capacitors after the hot pressing process are collected and the hot pressing process is completed. This reduces the tedious operations during the processing of the film capacitors, reduces the labor intensity, and improves the efficiency of the film capacitor processing. At the same time, with the cooperation of the opening and closing assembly 27, the conveyor assembly 3, and the cooling assembly 28, the film capacitors after hot pressing can be cooled in a timely manner, so that their internal structure will not be damaged due to slow manual handling and slow cooling, thereby improving their processing and production quality.

[0029] Considering that it takes a long time and is cumbersome to manually remove film capacitors from the hot pressing equipment, the heat inside the hot pressing equipment is lost quickly, which makes the next hot pressing take a long time and increases the energy consumption of the equipment. Figure 1-Figure 5The opening and closing assembly 27 includes a rotating wheel 271 rotatably mounted on the inner wall of the inner chamber 23. The rotating wheel 271 is used to drive a rack 272. The rotating wheel 271 is meshed with symmetrically arranged racks 272, each of which is fixedly connected to a symmetrically arranged opening and closing plate 273. A sliding groove 274 is provided on the processing chamber 21, and a sliding block 275 is fixedly connected to the opening and closing plate 273, which slides within the sliding groove 274. The sliding block 275 provides improved support for the opening and closing plate 273. A first motor 276 is fixedly mounted within the inner chamber 23 to drive the rotating wheel 271. The first motor 276 serves as the power source for the movement of the opening and closing plate 273. The opening and closing plate 273 is provided with a groove 33 that mates with the transmission belt 32. A locking slot 36 that mates with the opening and closing plate 273 is provided between two adjacent baffles 35. The groove 33 and the locking slot 36 ensure that the opening and closing plate 273 can close the processing chamber 21. When the conveying component 3 transports the film capacitors into the processing chamber 21, the first motor 276 is started, and the rotating wheel 271 is rotated by the first motor 276. The two racks 272 drive the opening and closing plates 273 along the movement direction of the racks 274 to the two ends of the opening of the processing chamber 21 through the rotating wheel 271. When the opening and closing plates 273 are opened, the film capacitors can be transported to the hot pressing processing area for hot pressing. After the transportation is completed, the opening and closing plates 273 can be quickly closed under the drive of the first motor 276 to seal the processing chamber 21, so that the film capacitors will not take too long to be transported, the heat loss inside the processing chamber 21 is reduced, and the energy consumption of the hot pressing equipment is reduced, thereby improving the work efficiency of the hot pressing processing of the film capacitors.

[0030] Considering that manually taking film capacitors to the hot pressing equipment is tedious and time-consuming, as time goes by, manual labor energy decreases, which easily leads to the failure to quickly remove the film capacitors during hot pressing, thus affecting the production quality of film capacitors. Figure 1 and Figure 5 The conveying assembly 3 includes two sets of transmission shafts 31 rotatably mounted on the base 1 and arranged in parallel. The two sets of transmission shafts 31 are connected by a transmission belt 32. A second motor 34 is fixedly mounted on the base 1 for driving the transmission shafts 31 to rotate. The second motor 34 serves as the power source for conveying the film capacitors. When conveying the film capacitors, the loading plate 4 is placed on the transmission belt 32, and the second motor 34 is started. Under the action of the second motor 34, the transmission shaft 31 rotates, and the film capacitors in the loading plate 4 are conveyed under the action of the transmission belt 32. This eliminates the need for manual removal of the film capacitors during hot pressing. Instead, the workers only need to place and collect the film capacitors at the starting end of the transmission belt 32, thereby reducing labor intensity and avoiding the inability to quickly remove the hot-pressed film capacitors due to a decrease in manual labor energy. This improves the work efficiency and production quality of the hot pressing process of the film capacitors.

[0031] Considering that when the film capacitor is cooled after hot pressing, the fan 282 blows air so that external impurities enter the processing chamber 21, making it easy for impurities to adhere to the film capacitor, causing the next step of processing to easily damage the film capacitor, affecting the processing quality of the film capacitor, refer to Figure 1 and Figure 5 A filter plate 283 is provided at the end of the air outlet 281, mounted on the inner wall of the processing chamber 21. The filter plate 283 is used to filter the interior of the processing chamber 21. The filter plate 283 has a plurality of filter holes 284 evenly distributed horizontally and vertically. The filter plate 283 filters the air entering the processing chamber 21, preventing impurities in the air from entering the processing chamber 21. This prevents impurities from adhering to the surface of the film capacitor during cooling, thereby improving the processing quality of the film capacitor in the next step.

[0032] Example 2

[0033] On the basis of Example 1, considering that when the loading plate 4 is being conveyed, the vibration generated by the transmission belt 32 may easily cause the loading plate 4 to shift position, resulting in an inaccurate hot pressing position, it is necessary to limit the position thereof, see Figure 1-Figure 5 A plurality of baffles 35 are fixedly connected to the transmission belt 32, and a loading plate 4 is detachably mounted between the baffles 35. The detachable mounting method can be to attach the loading plate 4 to the transmission belt 32 by bolts or the like so that the loading plate 4 can be mounted on the transmission belt 32 and can be transported along with the transmission belt 32. Before transporting, the loading plate 4 is mounted on the transmission belt 32 and restrained by the baffles 35 to prevent it from shaking during transport and causing displacement, thereby ensuring the correct position during the transport and hot pressing process.

[0034] Considering that when the fan 282 cools the film capacitor, if the wind direction is blowing directly on the film capacitor, it is easy to blow the film capacitor away or blow it off the loading plate 4, so it is necessary to ensure that the film capacitor will not be blown away during cooling. Figure 1-Figure 5 An air deflector 285 is installed on the top of the inner wall of the processing chamber 21. The air deflector 285 is tilted at an angle of 6-12 degrees. When the fan 282 blows air, the air deflector 285 guides the wind blowing into the processing chamber 21. The 6-12 degree tilt ensures that the wind does not blow directly toward the film capacitors, thereby preventing the film capacitors from being blown away by the fan 282 during cooling.

Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
