Description

Technical Field

[0001] The utility model relates to the field of picking equipment, in particular to an AOI picking equipment. Background Art

[0002] Automated Optical Inspection (AOI) is a high-speed and high-precision optical image inspection system. It uses machine vision as a standard inspection technology to improve the shortcomings of traditional human-powered optical instrument inspection. Automated Optical Inspection (AOI) is an effective inspection method for industrial automation. It uses machine vision as a standard inspection technology and is widely used in LCD / TFT, transistor and PCB industrial processes. In the prior art, a Chinese invention type patent with a public document number of CN116642894B discloses an AOI inspection device. In the document, multiple support components and limit modules are set. The multiple support components are equidistantly distributed relative to a reference point. The limit module is used to control the multiple support components to approach or move away from each other at the same time, which can adapt to the shape and size of the board to be inspected. There is no need to switch different drive motors for boards of different shapes to be inspected, thereby improving the inspection efficiency.

[0003] However, in this document, the workpiece is placed stationary below the AOI inspection lens during the inspection process. However, some workpieces are connected to a large number of components, such as a PCB is connected to a large number of electronic components, and the connection between some electronic components and the PCB is not firm. In a vibrating environment, they are easy to fall off from each other, resulting in poor contact. However, when the workpiece is placed stationary below the inspection lens, this situation is easy to be ignored, resulting in inaccurate inspection results. At the same time, the existing inspection equipment has a single operation method for the workpiece and cannot achieve synchronous action. For example, the workpiece can only move in parallel and cannot be flipped. As a result, when inspecting the other side of the workpiece, it is necessary to disassemble and install it again for re-inspection. Each time the workpiece is fully inspected, a long time of waiting is required, resulting in unnecessary waste of time and reduced efficiency. Therefore, improvement is needed. Utility Model Content

During the flipping process, the slide column 34 first moves out of the slide hole 19, the No. 2 slider 32 moves inward to compress the No. 2 spring 33, and after the flip frame 20 is flipped, the slide column 34 slides into the slide hole 19 again, thereby fixing the flip frame 20, and then the No. 2 slider 32 moves inward to compress the No. 2 spring 33. After the flip frame 20 is flipped, the slide column 34 slides into the slide hole 19 again, thereby fixing the flip frame 20, and then the No. The robot arm 9 removes the square sleeve 11 and releases the connection with the square block 35, and then the No. 1 stepper motor 7 continues to rotate, so that the flipped circuit board 30 moves again through the second AOI detection module 5 to detect the other side of the circuit board 30.
