Abstract

The invention provides a light bar, a light source and an optical detection device, which belong to detection devices for plate-shaped devices such as semiconductors and circuit boards. Locking head; multiple narrow light pieces are assembled in rows and arranged on the light-emitting surface; the light source includes a light source bracket, a lower light adjustment component, a medium light tile component, a glazing component and the above-mentioned light bar; two light bars are adjusted in the lower light The height adjustment is realized under the drive of the components; the light bar has a simple structure, modular design, good heat dissipation, and low cost. The light source using this light bar adopts two parallel light bars with oblique light outlets, and the height is adjustable; in summary, The light bar and the light source provide a stable and high-quality lighting environment for the optical detection device, facilitating popularization and application of detection equipment for circuit boards, silicon wafers and other board parts.

Description

technical field [0001] The invention belongs to the field of material feeding detection systems for plate-like devices such as semiconductors and circuit boards, and in particular relates to a light bar, a light source and an optical detection device. Background technique [0002] Circuit boards (including FPC and PCB HASL boards, immersion gold boards, gold-plated boards, immersion silver boards, immersion tin boards, OSP anti-oxidation boards, etc.) and silicon wafers are currently widely used in electronic and electrical systems. An important material to materialize circuit principles. In the prior art, the production of board materials or products such as circuit boards includes multiple processes, and the most important station is to perform optical measurement on the board surface of the board to be tested. However, the existing optical detection devices generally adopt the method of taking photos with a camera, that is, optical detection, but the ambient light provid...
