Description

technical field [0001] The invention relates to the field of film capacitor production and manufacturing, in particular to a longitudinal spraying range characterization control system of a film capacitor gold spraying machine. Background technique [0002] In the manufacturing process of film dielectric capacitors, gold spraying is a very critical production process. This process is to use arc or flame to melt the metal wire, and then use compressed air to spray it from the nozzle at high speed in the gap between the end surface of the metallized film of the capacitor core, so that the inner winding layer and the outer layer of the metallized film of the capacitor core The winding layers respectively form a metal electrode surface with the same potential, so as to achieve the purpose of leading out the electrodes; a certain number of capacitor cores to be sprayed are neatly placed in the core carrier gold-sprayed frame, and the gold-sprayed frame is placed on the transmissi...

Problems solved by technology

This process is to use arc or flame to melt the metal wire, and then use compressed air to spray it from the nozzle at high speed in the gap between the end surface of the metallized film of the capacitor core, so that the inner winding layer and the outer layer of the metallized film of the capacitor core The winding layers respectively form a metal electrode surface with the same potential, so as to achieve the purpose of leading out the electrodes; a certain number of capacitor cores to be sprayed are neatly placed in the core carrier gold-sprayed frame, and the gold-sprayed frame is placed on the transmission chain On the top, under the spray gun sent to the spray chamber by the transmission chain, the spray gun scans left and right as the horizontal direction, and the transmission chain drives the gold spraying frame to move slowly as the vertical direction to complete the gold spraying task of the capacitor core in a certain area; the gold spraying frame is used as the carrier of the capacitor core , its size is fixed, if the capacitor cores are filled horizontally in the frame, the distance of the spray gun scanning left and right along the horizontal direction can be fixed, but for different batches of different sizes, capacitor core groups may be arranged vertically in the frame Dissatisfaction, that is to say, the capacitor core group changes along the longitudinal distance in the frame. If the gold spraying process is sprayed with a fixed distance in the vertical direction, it will inevitably lead to waste of spraying materials; in order to save spraying materials, the CN102517534A patent document discloses a longitudinal The capacitor gold spraying device with controllable spraying range can adjust the stop spraying point according to capacitor cores of different specifications, but this device makes the peripheral circuit of the control system not simple enough, and the equipment failure rate is high
