Abstract

The invention relates to the technical field of SMT printing steel mesh appearance detection, in particular to a light-sensitive SMT detecting assembly. The light-sensitive SMT detecting assembly comprises a base, a support, a light source, a lens and a light sensing device. The top end of a vertical support body is fixedly connected with a transverse support body, and the other end of the transverse support body is fixedly connected with a lens holder. The light source is fixedly arranged on the upper surface of the lens, the bottom end of the vertical support body is fixedly connected to the side wall of the base, a first object table is a transparent device, the light sensing device is fixedly arranged on the upper surface of a second object table, a plurality of locating devices are fixedly arranged on the upper surface of the first object table, and an alarm is fixedly arranged below the second object table. A steel mesh and filler parts corresponding to holes of the steel mesh are placed on the first object table to form a light-tight layer, the steel mesh is tested through light irradiation of the light source and induction of the light sensing device on light, the workloads of workers are reduced, and meanwhile the test error rate is reduced.

Description

technical field [0001] The invention relates to the technical field of SMT printing steel mesh appearance inspection, in particular to a light-sensitive patch detection component. Background technique [0002] SMT is Surface Mount Technology (Surface Mount Technology) (abbreviation of Surface Mounted Technology), which is currently the most popular technology and process in the electronics assembly industry. SMT is an important link in the supply chain of the electronics manufacturing industry. The SMT printing stencil is a flat mold that must be used in the missing printing solder paste or dispensing process, and the SMT printing stencil is generally a steel mesh. SMT stencil manufacturing is an essential key process in the solder paste printing process, which directly affects the quality of the solder paste printing and is related to the quality of the entire SMT process. 70% of SMT quality problems are related to the printing of solder paste, and 35% of the defects are ...
