Abstract

The invention discloses an AOI detection clamp and a clamping method for a circuit board, and belongs to the field of electronic assembly and detection. The AOI detection clamp provided by the invention comprises fastening devices, locking devices, slide blocks, fixed supports, a frame, fixing bars and screws, wherein the two fixing bars are fixed on the frame in parallel, and a slide groove is arranged in each fixing bar; the two fixed supports are mutually parallel, vertically placed on the fixing bars, and matched with the slide grooves of the fixing bars through the fastening devices; a slide groove is arranged in each fixed support, and a plurality of movable slide blocks is installed in each slide groove; and an open hole capable of being matched with a circuit board installation hole is formed in each slide block, each slide block can be fixed to the circuit board and can be fixed to the slide groove of the corresponding fixed support through the locking devices. With the adoption of the AOI detection clamp and the clamping method for the circuit board, which are disclosed by the invention, the application range of AOI detection is expanded, thus more types of circuit boards can be subjected to the AOI detection; and meanwhile, the adverse effects of device damage, bonding pad falling-off and the like caused due to interference between the clamp and the devices of the circuit board are avoided.

Description

technical field [0001] The invention belongs to the field of electronic assembly and detection, and in particular relates to a circuit board AOI detection jig and a clamping method. Background technique [0002] AOI (Automatic Optical Inspection) is a device that detects common defects encountered in welding production based on optical principles. With the development of SMT technology, AOI detection technology has been applied more and more. When using AOI to inspect the circuit board, the circuit board needs to be firmly clamped. However, due to the limitations of AOI equipment itself, the fixtures it is equipped with cannot meet the demand. Contents of the invention [0003] In order to overcome the defects of the prior art, one of the objects of the present invention is to provide a circuit board AOI testing jig that is easy to operate, safe and reliable. At the same time, the invention also provides a circuit board clamping method. [0004] Technical scheme of the...
