Description

Technical Field

[0001] The utility model belongs to the technical field of resistor processing equipment, and in particular relates to a chip mounter for resistor processing. Background Art

[0002] Chip resistors, also known as name card fixed resistors, are a type of metal glass glaze resistors. They are made by mixing metal powder and glass glaze powder and printing them on a substrate using screen printing. They are resistant to moisture and high temperatures and have a small temperature coefficient. They can greatly save circuit space costs and make the design more refined. The resistor mounter is a device that accurately mounts the chip resistor on the surface of the workpiece. However, most resistor mounters do not clamp and fix the substrate when mounting the resistor, which can easily cause the substrate to move, resulting in inaccurate mounting. Therefore, a resistor mounting machine is needed to solve the above problems. Utility Model Content
