Multi-angle line light source used for detection

Abstract

The invention discloses a multi-angle line light source for detection, which comprises a plurality of strip line light sources, line light fixing plates arranged at both ends of the strip line light source for fixing, and fan fixing plates arranged on both sides of the line light fixing plate 1. A cover plate is provided on the top of the line light fixing plate. There are cooling fans on the fan fixing plate and the cover plate. The fan fixing plate and the line light fixing plate form a downward light-emitting gap. Both ends of the board, the base plate is attached with a heat dissipation silicone grease sheet, and the heat dissipation silicone grease sheet is attached to a PCB board. There are many high-power LED lamp beads on the PCB board. The inner cavity of the light source has a cylindrical condenser lens at the opening of the inner cavity of the line light source, the end plate is fixedly connected with the line light fixing plate, and the center line of the cover plate has a camera detection through hole. The invention has better light concentrating effect, stronger light and higher brightness, and is more conducive to the lighting detection of various defects of mobile phone screens and the surface of PCB boards, etc., and has better detection effect.

Description

Technical field [0001] The invention relates to an illumination device for detection, in particular to a multi-angle line light source for detection. Background technique [0002] Existing linear light sources used for detection, because the illumination angle and condensing design of the light source are not reasonable, or because the design of the light path is not scientific, the light of the light source is often not concentrated, the condensing effect is not good, and the brightness is not enough , The light is not strong enough, resulting in poor illumination and detection effects for various defect detection of mobile phone screens, PCB board surface detection, etc., and the quality or difference of the detected objects cannot be well presented, which is not conducive to detection. Therefore, it is necessary to develop a new multi-angle line light source for inspection to overcome these shortcomings. Summary of the invention [0003] In order to overcome the shortcomings o...

Problems solved by technology

[0002] The existing line light source used for detection, because of the unreasonable irradiation angle and spotlight design of the light source, or the unscientific design of the optical path, often causes the light of the light source to be not too concentrated, the light spotting effect is not good, and the brightness is not enough , the light is not strong enough, resulting in poor illumination and detection effects for various defect detection of mobile phone screens, PCB board surface detection, etc., and the quality or difference of the detected object cannot be well presented, which is not conducive to detection
