Embodiment Construction

[0046] The embodiments of the present application will be described in detail below with reference to the accompanying drawings and examples, so as to fully understand and implement the implementation process of how to apply technical means to solve technical problems and achieve technical effects in the present application.

[0047] It should be noted that the embodiments in the present application and the features of the embodiments may be combined with each other in the case of no conflict.

[0048] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relationship between various components under a certain posture (as shown in the accompanying drawings). The relative positional relationship, the movement situation, etc., if the specific posture changes, the directional indication also changes accordingly.

[0049] In the invention, unless otherwise expr...

Abstract

The invention provides an AOI detection device and a detection method thereof. The AOI detection device includes a frame, a feeding mechanism, a first buffer platform mechanism, a first material moving mechanism, a visual positioning mechanism, a platform mechanism, a detection mechanism, a second material moving mechanism mechanism, the second cache platform mechanism and the blanking mechanism. The present invention automatically carries out the feeding and detection of workpieces through the cooperation of various mechanisms, which has a high degree of automation and improves production efficiency. In particular, the platform mechanism can automatically energize the workpieces without manual powering of the workpieces; and the visual positioning mechanism can detect the workpieces Then control the first material handling mechanism to place the workpiece on the appropriate position of the platform mechanism to ensure that the LCM can be powered on and detected smoothly; the first cache platform mechanism can locate the position of each component on the workpiece to avoid the relative position of each component on the workpiece. precise.

Description

technical field [0001] The invention relates to the technical field of AOI (Automated Optical Inspection, automatic optical inspection) detection, in particular to an AOI detection device and a detection method thereof. Background technique [0002] The full name of AOI (Automated Optical Inspection) is automatic optical inspection, which is a device that detects common defects encountered in welding production based on optical principles. It has now become an important testing tool and process quality control tool for the electronics manufacturing industry to ensure product quality. AOI is to compare the standard digital image stored in the AOI system with the actual detected image through the graphic recognition method, so as to obtain the detection result. Images are compared to detect product defects. [0003] When the display module is produced, it is necessary to perform defect detection on the display module to detect whether the display module has defects such as a...
