Description

Technical Field

[0001] The utility model relates to the technical field of PCB detection, and in particular to a PCB detection light source and a detection device. Background Art

[0002] PCB is a basic component in electronic equipment, which plays a role in carrying various electronic components. Among them, there are many types of PCBs, and the detection device in the prior art cannot meet the detection requirements of various series of PCBs at the same time, and has the defect of poor compatibility. After searching, a Chinese patent with the authorization announcement number CN217879929U discloses a PCB detection light source and a detection device. The PCB detection light source includes a light source housing, and a camera hole and an observation hole are opened on the light source housing. By arranging a main light source component and a plurality of fill light source components between the camera hole and the observation hole, and making each fill light source component have a different inclination angle relative to the observation hole, the fill light effect corresponding to each fill light source component is different, so that the staff can enable the fill light source component according to the type of PCB, meet the lighting requirements of various PCBs, and improve the compatibility of the PCB detection light source; at the same time, a heat dissipation component is arranged on the cavity wall of the light source cavity, and the heat dissipation problem of the main light source component and the fill light source component is solved at the same time, and each light source component can be uniformly dissipated, so that the detection device only needs to install the PCB detection light source on each of its detection stations to meet the detection and heat dissipation requirements, reducing the difficulty of installation. In summary, the present application has the advantages of high compatibility and simple installation.

[0003] However, in actual use, since the light source housing and the camera unit are both fixed structures, this solution can only detect flat PCB panels. Once uneven placement or angled stacking occurs on the conveyor belt, blind spots will appear, affecting the accuracy of the entire detection work.

[0004] Therefore, we have made improvements to this and proposed a PCB detection light source and detection device. Utility Model Content
