Description

Technical Field

[0001] The invention relates to the technical field of capacitor processing, in particular to a hot air circulation oven for producing microwave oven high-voltage capacitors. Background Art

[0002] At present, capacitors are one of the electronic components used in large quantities in electronic equipment. They are widely used in circuits for DC isolation, AC connection, coupling, bypass, filtering, tuning circuits, energy conversion, control, etc. Capacitors are usually referred to as capacitors, represented by the letter C. They are devices that hold electric charge. Any two conductors (including wires) that are insulated from each other and very close to each other constitute a capacitor. During the stamping process, the capacitor shell needs to be added with an appropriate amount of lubricating oil to extend the life of the die and improve the quality of the capacitor shell. Therefore, the stamped capacitor shell must be cleaned. In order to remove the oil stains on the capacitor shell during processing, the capacitor shell needs to be cleaned, and the cleaned capacitor shell needs to be dried.

[0003] After searching, a Chinese invention patent disclosed a drying device for the production and processing of capacitor shells with publication number CN119022602A, which solves the problems of low drying efficiency, poor drying effect and inconvenient movement in the prior art. The device comprises a shell and a heater, the output end of the heater is fixedly connected with an air inlet pipe by screws, the air inlet pipe fixed sleeve is arranged inside the shell, the inside of the air inlet pipe is fixedly connected with a sliding sleeve by screws, the sliding sleeve is slidingly assembled with a sliding block inside, and the servo motor is started by setting the first screw, the second screw and other structures, and the servo motor drives the first screw to rotate intermittently forward and reverse, and the air guide vane is rotated left and right by the sliding sleeve, and the drying box is moved left and right by the second screw and the fixed block, and the rotation direction of the bottom of the air guide vane is opposite to the movement direction of the drying box, which reduces the moving stroke and increases the flow range of hot air, accelerates the air drying of parts, and achieves the effect of improving drying efficiency.

[0004] Existing ovens do not have a special fixing structure for capacitors during the drying process. If the capacitors are not fixed properly during drying, they may be displaced by the hot air, resulting in uneven drying, and may even collide with other parts inside the oven and be damaged. There may be no effective way to deal with the steam after the liquid on the outer surface of the capacitor evaporates. The steam diffused in the oven may affect the drying effect, and if the steam condenses on the inner wall of the oven, it may cause corrosion and other damage to the internal structure of the oven.

[0005] Therefore, the existing hot air circulation oven for producing high-voltage capacitors in microwave ovens cannot meet the needs in actual use, so there is an urgent need for improved technology in the market to solve the above problems. Summary of the invention

The capacitor is stable in position during the drying process to avoid shaking that affects the drying effect or causes damage to the capacitor. The blast structure allows the hot air to be evenly blown to the capacitor, improving the uniformity and efficiency of drying.

[0034] Working principle: When working, pull the control lock 232 to make the door panels 231 rotate toward each other, thereby opening the inner cavity of the protective frame 21. At this time, pull the extrusion plates 74 toward each other to make the spring on the sliding rod 73 contract, so that the extrusion plates 74 on the upper and lower sides of the rotating shaft 71 slide relative to each other, thereby increasing the distance between the extrusion plates 74 and the rotating shaft 71. At this time, the personnel places the capacitor between the extrusion plates 74 and the rotating shaft 71. At this time, release the extrusion plates 74 to make the spring on the outer surface of the sliding rod 73 extend, so that the extrusion plates 74 and the rotating shaft 71 are close to each other, thereby squeezing and fixing the capacitor, and then push the door panel 231 in the opposite direction, so that the door panel 231 rotates in the opposite direction, so that the door panel 231 closes the inner cavity of the protective frame 21. When drying, the heating control structure 9 is started, and the power of the control module 93 is transmitted to the heating tube 83 through the transmission cable 92, so that the air at the lower end of the top plate 22 is heated, and the blowing structure 10 is further started to rotate the output end of the micro-motor in the inner cavity of the rotating shaft 103, so that the fan blade 104 rotates, thereby blowing the hot air heated by the heating tube 83 to the fixed structure 7, so that the capacitor is dried with hot air. When the capacitor is dried, the liquid on the outer surface of the capacitor evaporates due to the heat, so the evaporated liquid rises upward, and then the pumping structure 4 is started, so that the pumping pump 41 starts to work, and the liquid between the bottom plate 1 and the placement plate 62 is transported to the condensation structure 3 through the water pipe 42 and the connecting rod 43, so that the low-temperature liquid enters the inner cavity of the condenser tube 32, so the temperature of the outer surface of the condenser tube 32 is reduced, so that the heated capacitor liquid vapor adheres to the outer surface of the condenser tube 32, and at this time, the condensed water on the outer surface of the condenser tube 32 falls on the upper end surface of the unidirectional water permeable membrane 51 under the action of gravity, and further makes the condensed water fall on the upper end surface of the bottom plate 1 through the unidirectional water permeable membrane 51. At this time, the water flow between the bottom plate 1 and the placement plate 62 is circulated in the pumping structure 4 through the pumping pump 41, the water pipe 42 and the connecting rod 43, so that the steam during drying is condensed and collected. When the air blowing structure 10 performs air blowing drying, the fixed structure 7 rotates due to the effect of wind force, thereby achieving cyclic and uniform drying of the capacitor.
