[0003] like figure 1 , figure 2 , image 3 As shown, in the powder tank, the carrier paper tape must be transported by the pin wheel to ensure the accuracy of transmission. Therefore, before coating the epoxy resin, it is necessary to punch holes on the carrier paper tape and masking tape, and use it with the pin wheel; Masking tape is viscous, so during the punching process, there may be paper dust attached to the edge of the hole; in this way, during the later process of the material body adhering to the epoxy resin, these paper dust attached to the edge of the hole will be Constantly being squeezed by the pin wheel, it falls into the epoxy resin powder tank, and even adheres to the capacitor body being coated with epoxy resin. After the subsequent preheating and multiple coatings of the automatic coating machine, it will When encapsulated on the capacitor body, it is difficult to see the defect with the naked eye; if it is not found in the first encapsulation process, it will be more difficult to remove it in the subsequent encapsulation process, and even flow into the hands of customers

The invention discloses a powder tank device of an automatic coating machine, which comprises a support, a powder tank, a pin wheel, a cover plate and a hairbrush, wherein the powder tank, a central shaft of the pin wheel, the cover plate and the hairbrush are fixed to the support; the pin wheel is positioned right above the powder tank; the powder tank is covered by the cover plate, which is under the pin wheel; a product position-yield part is formed on the cover plate; the hairbrush is positioned right above the cover plate; and the head of the hairbrush brushes the side surface of the pin wheel. The powder tank device of an automatic coating machine provided by the invention can clean paper scraps attached to the side surface of the pin wheel so as to prevent the paper scraps from falling in the powder tank to influence the product quality.
Description
technical field [0001] The invention relates to capacitor production equipment, in particular to a powder tank device of an automatic coating machine. Background technique [0002] In the production process of ceramic capacitors, it is necessary to arrange the wires on the carrier paper tape (that is, kraft paper tape) first, and fix it with masking tape (that is, high-temperature tape), and then drive the wires through the transmission carrier paper tape for subsequent Wire bonding, chip insertion, soldering, coating, curing and other processing. Among them, the coating process is to adsorb epoxy resin on the surface of the capacitor body with ceramic chips welded at the end of the wire, so as to protect the capacitor body from damage and make the capacitor body moisture-proof. The coating process is completed using an automatic coating machine. First, a layer of epoxy resin is coated on the capacitor body through the powder tank, and then the capacitor carrier coated with...
