Automatic inspection equipment for defects of PCB

Abstract

The invention discloses automatic inspection equipment for defects of a PCB. The automatic inspection equipment comprises a base, supporting legs are fixedly mounted at the bottom of the base; a workbench is fixedly installed in the middle of the base. Guide rails are arranged on the two sides of the workbench, clamping mechanisms are symmetrically arranged on the guide rails and slidably connected with the guide rails, a first conveying belt and a second conveying belt are fixedly installed at the two ends of the base, a supporting frame is fixedly installed above the base, a third conveyingbelt is fixedly installed in the middle of the supporting frame, and an inspection mechanism is fixedly installed at the top of the supporting frame. According to the invention, the third conveyor belt, the turntable and the clamping mechanism are matched; rapid feeding, alignment and clamping of the PCB are realized; the inspection mechanism can complete appearance inspection and power-on inspection of the PCB, qualified products can be discharged through the first conveying belt after inspection, unqualified products can be recycled through the second conveying belt, automatic inspection ofdefects of the PCB is achieved, and the inspection efficiency of the PCB is greatly improved.

Description

technical field [0001] The invention relates to the field of PCB circuit boards, in particular to an automatic detection device for PCB circuit board defects. Background technique [0002] PCB (printed circuit board) is a printed circuit board, referred to as a printed board, and is one of the important components of the electronics industry. Almost every kind of electronic equipment, ranging from electronic watches and calculators to computers, communication electronic equipment, and military weapon systems, as long as there are electronic components such as integrated circuits, in order to make the electrical interconnection between various components, printed circuit boards must be used. plate. The printed circuit board is composed of an insulating base plate, connecting wires and pads for assembling and welding electronic components, and has the dual functions of a conductive line and an insulating base plate. It can replace complex wiring and realize the electrical co...

Problems solved by technology

However, the operator needs to put the PCB circuit board to be inspected on the inspection table, and manually mark the detected defect position, then manually take it out and enter the next repair process

This kind of mechanical inspection relies on manual operation, the degree of automation is low, the inspection speed is slow, and the operation is cumbersome
