Pre-alignment machine for PCB processing

Abstract

The invention discloses a pre-alignment machine for PCB processing. The pre-alignment machinecomprises a rack main body, wherein the top of the rack main body is connected with an outer cover, one side of the rack main body is provided with a defective product moving device, the rack main body is provided with a bearing tray moving device on the lower side of the defective product moving device, the middle position of the rack main body is provided with a visual inspection device, and a correcting device is mounted on the other side of the rack main body. According to the invention, CCD and X-ray can be installed on a visual inspection device at the same time, so that interchangeability is achieved; two groups of main racks are symmetrically arranged left and right, so that left and right mounting can be realized, and left and right operation surfaces of the same rack can be exchanged; butt joint with various devices is realized, including butt joint with a mechanical arm feeding machine, butt joint with a common feeding machine, butt joint with an edge cutting and grinding machine and butt joint with a target drilling machine; and through the cooperative use of the visual detection device and the tray bearing and material moving device, the overall plate surface detection is realized, and the situation of inaccurate alignment is reduced.

Description

technical field [0001] The invention belongs to the technical field of graphic image detection and alignment, and in particular relates to a pre-alignment machine for PCB board processing. Background technique [0002] The existing PCB pre-alignment machine is part of the PCB trimming and edging production line, which is used to judge whether the target hole is accurate, determine the direction and position of the PCB through the target hole, and perform corresponding position correction, that is, realize pre-alignment. Generally, there are two ways to realize pre-alignment visual inspection, one is CCD and the other is X-ray, but the old equipment needs to be built on different racks, which cannot achieve interchangeability. At the same time, due to the uncertainty of the edge cutting and edging production line, the existing equipment cannot adapt to a variety of different usage scenarios, including different loading machines, and the old equipment cannot realize the overal...

Generally, there are two ways to achieve pre-alignment visual inspection, one is CCD, the other is X-ray, but the old equipment needs to be built on different racks, which cannot achieve interchangeability

At the same time, due to the uncertainty of the edge cutting and edging production line, the existing equipment cannot adapt to a variety of different usage scenarios, including different loading machines, and the old equipment cannot realize the overall board surface inspection of the PCB, which is likely to cause poor alignment
