Description

A six-sided inspection and packaging device for electronic components

technical field

The utility model relates to the technical field of electronic component appearance inspection and packaging devices, in particular to a six-sided inspection and packaging device for electronic components.

Background technique

In the production line of batch testing and screening of electronic components, in the final visual inspection and packaging process, it is necessary to conduct a six-sided visual inspection of the tested and screened components with qualified electrical properties to screen out defective products and then pack them. In order to reduce manual operations, increase the degree of automation, and reduce the equipment footprint, it is usually required to integrate the six-sided visual inspection function and the packaging function into one device. For the material input mode of the integrated equipment, it is required to be consistent with the material output mode of the previous process, which can minimize the manual operation of material transfer and facilitate the automatic transfer of materials between devices. The previous process of this equipment is usually testing equipment, and there are mainly two ways of component output of automatic measuring equipment. One is a box-type test equipment, and the components of the output port of the equipment are installed in the carrier box. Another type of test equipment does not use the output of the carrier box, and the components are output in bulk. Therefore, for the six-sided inspection and packaging process, there are also two feeding methods required, one is the box-type feeding method, and the other is the bulk material feeding method.

For the way of bulk material feeding, the existing technology is to arrange the electronic components on the periphery of the horizontally rotating transparent glass disc, and then observe the movement of the electronic components along the circle by 6 cameras arranged around the disc. The six-sided appearance of each component of the camera in each direction. In this way, the shooting angle and distance of each component will be different. The output of the component is usually in the form of bulk material, which will bring great inconvenience to the subsequent taping and packaging. , can only use the vibrating plate and linear vibrating rail plus the optical recognition device to re-position the capacitors, and then the electronic components can be taken out from the linear vibrating rail for packaging, which will increase the cost of the packaging device, and it is not easy to make the six-sided appearance The inspection device and the packaging device are integrated in one piece of equipment, so that the visual inspection and packaging can only be separated into two pieces of equipment.

For the way of loading cassettes, the prior art, such as a patent application with the publication number CN112858322A, discloses that the components in the cassettes are first inspected facing upwards, and then a vertical suction head array is used to place a row of components in the cassettes. The components are picked up and passed through two cameras in a linear motion to complete the visual inspection of the two sides. After the end, the row of components is returned to the original row position of the carrier box. Then complete the same way row by row for the components in the carrier box. After the line-by-line inspection is completed, the carrier box moves to another station, and another horizontal suction head array picks up a row of components in the carrier box, and passes through the other two cameras in a straight line to complete the other two 2-side inspections. Finally, the flipping device turns the bottom of the capacitor to the front, and another camera takes pictures of each capacitor on this side. So far, the components of the entire carrier box have completed the visual inspection of 6 sides, and the components are still kept in the original carrier box. For the subsequent braiding and packaging device, it can be directly taped and packaged after taking the material from the carrier box, eliminating the need for a uniform orientation of the front side of the component and an directional operation device for the orientation of the electrical polarity, which can save costs and can also The six-sided inspection device is integrated with the tape packaging device, but the appearance inspection part has multiple stations, and the equipment structure of each station is complex, the overall equipment size is large, and the cost is also high.
