Problems solved by technology
The common plug-in process in the circuit board mounting factory is manual operation or manual machine mixed plug-in, and then manually inspected and then enters the wave soldering equipment for soldering processing, so there are often direct plug-in omissions caused by human negligence in this process, The phenomenon of insertion deviation, even if there are inspectors behind the furnace to check, still increases the risk of defective products outflow and reduces production efficiency

Embodiment
[0020] The present embodiment provides a visual-based stereotypes and defective product detection method, which includes the following steps:
[0021] First of all, trim the electronic components. During the trimming process, the pneumatic unit provides power. Through the processing of the solenoid valve, the pin bending cylinder of the electronic component moves first, and the pins are bent according to the width required by the size. After the bending is completed The pin cutting cylinder of electronic parts starts to trim the pins; the trimmed electronic parts are plugged into the circuit board;

The invention discloses vision-based direct-insertion defective product shaping and detection equipment. The equipment comprises a shaping device and a detection device, wherein the shaping device comprises an adjustment block, an electronic component pin bending cylinder, an electronic component pin shearing cylinder, an electromagnetic valve and a pneumatic unit; a to-be-trimmed electronic device is placed on the adjustment block, and the electronic component pin bending cylinder and the electronic component pin shearing cylinder are connected with the pneumatic unit through the electromagnetic valve; the detection device comprises an alarm module, a microcontroller, an upper computer, an industrial camera, an adjustable light source, a detection module and a conveying chain; and the microcontroller is connected with the alarm module, the upper computer, the adjustable light source, the detection module and the conveying chain respectively, the industrial camera is connected with theupper computer, and the detection module is also connected with the conveying chain. Through the equipment, convenience is brought to trimming work and statistical work of three types of electronic components in different sizes by an operator; and when a trimmed product is inserted into a circuit board, subsequent inspection also can be performed.
Description
technical field [0001] The invention relates to a pre-furnace inspection device of wave soldering equipment, in particular to a vision-based in-line defective product sizing and testing equipment. Background technique [0002] With the increasing miniaturization of electronic components and the high integration of PCB boards, the traditional method of manual visual inspection has been completely unable to meet the almost demanding high pass rate requirements for modern product quality. Manual offline inspection is carried out in batches and in stages, ranging from one day to several days, mainly determined by the batch size of the product. Due to the "post-event" effect of the offline detection method, real-time detection and alarm in the production process cannot be realized, so that product defects cannot be discovered and corrected in time, resulting in a waste of production materials. Not only that, the off-line detection method relies heavily on people, and the detecti...
