Visual detection robot for flexible circuit board and transmission method of visual detection robot

Abstract

The invention relates to a visual detection robot for a flexible circuit board and a transmission method of the visual detection robot. The visual detection robot comprises four parts of a feeding mechanism, a rotation mechanism, a visual assembly and a discharging mechanism. The feeding mechanism grabs the to-be-detected flexible circuit board, infrared rays emitted by an infrared transmitter arereceived by an infrared receiver, whether a pneumatic suction cup is aligned with a detection station or not is judged, and it is ensured that a to-be-detected workpiece is placed on the detection station smoothly and steadily. An image collecting module collects images and transmits the images back to a computer, and finally, sorting and discharging are completed by the discharging mechanism. Arotation disc can make dividing movement of 90 degrees once, the rotation disc is self-locked during every rotation of 90 degrees and stays by a predetermined time interval, and at the moment, the visual assembly captures images and transmits the images back to the computer for processing. The rotation mechanism can integrate four stations on one disc, the space is saved, the transmission precision is also improved, the visual detection robot is suitable for conveying of the flexible circuit board, transmission is smooth, vibration is avoided, and positioning is accurate.

Description

technical field [0001] The invention relates to a detection robot, in particular to a visual detection robot for a flexible circuit board and a transmission method thereof. Background technique [0002] Flexible circuit boards, also known as "soft boards", are printed circuits made of flexible insulating substrates, which can be bent, wound, and folded freely. Flexible circuits provide excellent electrical performance, can meet the design needs of smaller and higher density mounting, and also help reduce assembly processes and enhance reliability. FPCs may have defects such as broken seams, chain seams, pinholes, and folds. If the above defects are inspected only by human eyes, it is time-consuming and labor-intensive, and they are easy to miss. Therefore, automated equipment is needed for automatic detection. [0003] In the prior art, automatic equipment for testing flexible circuit boards usually uses linear rollers to transport the flexible circuit boards to be tested t...

Problems solved by technology

However, due to the softness of the flexible circuit board, the above solution has great disadvantages. The flexible circuit board on the way of transmission is very easy to be caught by the roller table on the linear roller table. Vibration is not conducive to the positioning operation of the detection module to detect the workpiece
