A chip resistor precision engraving machine

Abstract

The invention discloses a precision engraving machine for patch resistors, which comprises a track bottom plate, a track chute inside the track bottom plate, two track support plates distributed in parallel fixedly connected to the top of the track bottom plate, the two track Gravity slides are slidably connected between the support plates, and the inside of the track support plate has a slide plate groove for the slide of the gravity slide plate, a trigger switch is installed on the inner bottom of the slide plate groove, and a drive motor is installed on the top of the gravity slide plate. The bottom of the output shaft of the drive motor is fixedly connected with a chip resistor grinding disc, and the bottom of the outer end surface of the chip resistor grinding disc is provided with rounded corners. In the present invention, firstly, through the automatic grinding structure, the consumption of manpower is reduced, and the effect of grinding is improved; secondly, the feeding of chip resistors is realized while discharging, thereby improving the processing efficiency. Finally, a stable conveying mechanism is adopted to improve the effect of grinding chip resistors.

Description

technical field [0001] The invention relates to the technical field of chip resistance processing devices, in particular to a chip resistance precision engraving machine. Background technique [0002] Chip resistors are also business card-type fixed resistors, which are one of the metal glass glaze resistors. It is a resistor made by mixing metal powder and glass glaze powder and printing it on the substrate by screen printing. Resistant to humidity and high temperature, with a small temperature coefficient. It can greatly save the cost of circuit space and make the design more refined. SMD components have the advantages of small size, light weight, high installation density, strong shock resistance, strong anti-interference ability, good high frequency characteristics, etc., with small size, light weight, suitable for reflow soldering and wave soldering, stable electrical performance, reliable High performance, low assembly cost, matching with automatic placement equipme...
