Abstract
Description
Technical Field
[0001] This utility model relates to the field of visual inspection technology, and in particular to a visual inspection device for electronic components. Background Technology
[0002] In machine vision inspection systems, the inspection light source is one of the most important components. The light emission effect of the inspection light source directly affects the inspection accuracy of electronic components. Inspection light sources include coaxial light sources, linear light sources, ring light sources, and so on.
[0003] Existing visual inspection devices typically illuminate electronic components by projecting light vertically downwards from a coaxial light source, and then a camera photographs the illuminated component to determine its compliance. This method has the following drawbacks: poor illumination of the outer periphery of the electronic component results in a relatively blurry image of the component's outer edge, hindering accurate inspection.
[0004] Therefore, it is necessary to design a visual inspection device for electronic components to improve the accuracy of electronic component inspection.
[0005] The above information is provided as background information only to aid in understanding this disclosure and does not constitute an assertion or admission that any of the above content can be used as prior art relative to this disclosure. Utility Model Content

[0014] The housing forms a mounting cavity for accommodating the detection light source.
[0015] Optionally, the electronic component visual inspection device further includes a lifting rod and a vertical lifting device for driving the lifting rod along the insertion hole into the inspection hole;
[0016] The top of the lifting rod is equipped with a suction nozzle for adsorbing electronic components.

[0046] Please refer to Figures 1 to 5 This utility model provides a visual inspection device for electronic components, including a detection light source 1. The detection light source 1 is used to provide illumination, illuminating the electronic components to be inspected and highlighting surface defects of the electronic components.
[0047] The detection light source 1 includes a mounting base 11 and a PCB light board 12 mounted on the mounting base 11; the mounting base 11 serves to support the PCB light board 12, and the PCB light board 12 emits light to illuminate electronic components.
[0048] In this embodiment, the mounting base 11 is provided with a detection hole 111 for electronic components to enter, and the mounting base 11 is arranged with a plurality of inclined mounting outer surfaces 112 in a circular array around the center line of the detection hole 111. Each inclined mounting outer surface 112 is provided with a light-emitting hole 113, which passes through the mounting base 11 and connects to the detection hole 111. The PCB lamp board 12 is attached to the inclined mounting outer surface 112, and the lamp beads on the PCB lamp board 12 pass through the light-emitting hole 113 and emit light downward at an angle through the light-emitting hole 113. The setting of the inclined mounting outer surface 112 allows the PCB lamp board 12 to be directly attached to the inclined mounting outer surface 112, so that the lamp beads emit light downward at an angle, simplifying the installation of the PCB lamp board.
[0049] In summary, the electronic component visual inspection device has multiple inclined mounting outer surfaces 112 arranged in a circumferential array on the mounting base 11, and each inclined mounting outer surface 112 has a light-emitting hole 113. The PCB lamp board 12 is attached to the inclined mounting outer surface 112 so that the light emitted by the lamp beads is inclined downward. When the electronic component enters the inspection hole 111, the light emitted downward can illuminate both the top surface and the outer surface of the electronic component, thereby improving the inspection accuracy. That is, the electronic component visual inspection device in this embodiment, by allowing the electronic component to enter the inspection hole 111 and arranging multiple inclined downward light-emitting PCB lamp boards 12 around the inspection hole 111, effectively improves the illumination effect on the electronic component, which is beneficial to improving the inspection accuracy of the electronic component.
[0050] It should also be noted that the PCB light board 12 is fitted onto the inclined mounting outer side 112, which is easy to install and can accurately define the tilted light emission angle of the lamp beads, improving the assembly efficiency and accuracy of the electronic component visual inspection device, and enabling the PCB light board 12 to illuminate the top and outer side of the electronic components. In this embodiment, the mounting base 11 is provided with threaded holes, and screws pass through the PCB light board 12 and are screwed into the threaded holes on the mounting base 11, thereby making the PCB light board 12 fit against the inclined mounting outer side 112.
[0051] Optionally, the electronic component visual inspection device further includes a housing 2; the housing 2 includes an upper housing 21 and a lower housing 22, the upper housing 21 is provided with a camera imaging hole 211 communicating with the detection hole 111, and the lower housing 22 is provided with an insertion hole 221 for electronic components to enter the detection hole 111, the insertion hole 221, the detection hole 111 and the camera imaging hole 211 are coaxial; the housing 2 forms a mounting cavity for accommodating the detection light source 1.
[0052] The outer casing 2 supports and protects the detection light source 1. In addition, the outer casing 2 surrounds the detection light source 1, preventing excessive light from escaping to the outside and confining the light within the mounting cavity. This not only improves the brightness of the light but also prevents strong light from injuring people.
[0053] Optionally, the electronic component visual inspection device further includes a lifting rod 3 and a vertical lifting device for driving the lifting rod 3 into the inspection hole 111 through the insertion hole 221; the top of the lifting rod 3 is provided with a suction nozzle 31 for adsorbing electronic components. In this embodiment, the suction nozzle 31 adsorbs electronic components, and then the vertical lifting device drives the lifting rod 3 into the inspection hole 111 through the insertion hole 221. Then, the inspection light source 1 illuminates the electronic components and the camera 4 takes pictures of the electronic components for inspection. Finally, the lifting rod 3 returns along the original path and exits the inspection hole 111, placing the inspected electronic components in a suitable position, which here refers to a qualified tray or an NG tray.
[0054] Optionally, the electronic component visual inspection device also includes a camera 4 and a lens 5 mounted on the camera 4, with the lens 5 facing the camera's image capture hole 211.
[0055] Optionally, the upper shell 21 is provided with a positioning groove 212 for positioning the mounting base 11, and the mounting base 11 has an annular positioning portion 114 for fitting against the side wall of the positioning groove 212; the positioning groove 212 forms part of the mounting cavity. Specifically, the bottom shape of the positioning groove 212 matches the outer peripheral shape of the annular positioning portion 114, thereby accurately positioning the mounting base 11.
[0056] Optionally, the mounting base 11 has a positioning surface for pressing against the top surface of the lower housing 22, and the top surface of the annular positioning portion 114 conforms to the bottom wall of the positioning groove 212. Specifically, the top surface of the annular positioning portion 114 conforms to the bottom wall of the positioning groove 212, the outer periphery of the annular positioning portion 114 conforms to the bottom shape of the positioning groove 212, and the positioning surface of the mounting base 11 away from the annular positioning portion 114 presses against the top surface of the lower housing 22, thereby achieving complete positioning of the mounting base 11.
[0057] Optionally, the inner wall surface of the detection hole 111 is a diffuse reflective surface. The diffuse reflective surface reflects the light from the PCB light board 12 and can reflect some of the light to the outside of the electronic components, avoiding dead corners around the electronic components that are not illuminated.
[0058] Optionally, all light-emitting apertures 113 are arranged in a circumferential array around the center line of the detection aperture 111.
[0059] Optionally, a first magnet is provided on the upper shell 21, and a second magnet is provided in the mounting base 11; when the mounting base 11 is inserted into the mounting cavity, the first magnet and the second magnet attract each other magnetically. Specifically, when the mounting base 11 is placed in the upper shell 21, the first magnet attracts the second magnet, causing the outer periphery of the annular positioning part 114 to fit against the side wall of the positioning groove 212, thus maintaining the relative position of the mounting base 11 with the upper shell 21 and making the installation of the mounting base 11 more convenient.
[0060] Optionally, the mounting base 11 is an insulated plastic base.
[0061] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application.
