Problems solved by technology
Most manufacturers of chip resistor appearance visual inspection in the prior art use manual visual inspection, which has poor consistency, low efficiency, and high labor costs
Some manufacturers use CCD for appearance visual inspection, but the structure of the equipment is complex, the cost is high, and the accuracy of CCD appearance visual inspection is not high due to the low resolution and contrast of the supporting light source

The invention relates to six-face visual inspection equipment for surface mounted resistors. The equipment comprises a rigid structure body, a computer mainframe, a display, a pneumatic transmission mechanism, a feeding system, control buttons, an operation rotating plate, a visual inspection mechanism and a light source. The rigid structure body provides a rigid supporting frame for the inspection equipment; the pneumatic transmission mechanism provides movements of the operation rotating plate and the inspection mechanism; the light source provides a visual illumination imaging light source for to-be-inspected surface mounted resistors. The six-face visual inspection equipment for the surface mounted resistors has advantages that positioned and fixed input of the surface mounted resistors into the operation rotating plate is realized through the feeding system, an orientation monitoring CCD (charge coupled device) mechanism and a size monitoring mechanism are arranged on the same outer periphery of the operation rotating plate, and the equipment is simple in structure and low in cost; further, the semi-bowl or bowl shaped light source covers the to-be-inspected surface mounted resistors, and consequently high resolution and contrast ratio can be provided, and accuracy in quick visual inspection is improved.
Description
technical field [0001] The invention relates to a chip resistor visual detection device. Background technique [0002] SMD resistors are indispensable electronic components in electronic information circuits. The produced SMD resistors must undergo necessary visual inspection to ensure the quality before they can be packaged, stored and transported when the resistance value is qualified. Most manufacturers of chip resistor appearance visual inspection in the prior art use manual visual inspection, which has poor consistency, low efficiency, and high labor costs. Some manufacturers use CCD for appearance visual inspection, but the structure of the equipment is complex, the cost is high, and the accuracy of CCD appearance visual inspection is not high due to the low resolution and contrast of the matching light source. Contents of the invention [0003] Based on this, in view of the prior art, the technical problem to be solved by the present invention is to provide a six-s...
