Glue point inspection method and device

Abstract

The invention relates to the field of image processing, and discloses a glue point inspection method and device. The glue point inspection method comprises the steps of acquiring a first image of the surface of an object to be inspected; separating a glue point in the first image of the surface of the object to be inspected from the background to obtain a second image with the background being removed; and judging whether the glue point in the second image is qualified or not, and displaying a judgment result. The embodiment of the invention further provides a glue point inspection device. Whether the glue point at the surface of the object to be inspected is qualified or not can be effectively inspected according to the invention. Meanwhile, the labor cost can be saved.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a glue point inspection method and device. Background technique [0002] Glue dispensing is usually the application, potting, and dripping of electronic glue, oil or other liquids on the product, so that the product can play the role of sticking, potting, insulating, fixing, and smoothing the surface. Since dispensing will significantly improve the reliability and life of products, with the rapid development of electronic products, the requirements for dispensing are getting higher and higher. The inspection of glue spots on the surface of products has gradually become an indispensable part of improving product quality. ring. The existing technology mainly adopts manual detection, and manually uses tools such as a magnifying glass to observe whether the glue spots on the surface of the product are qualified, so as to judge whether the product is qualified. [0003] In the proces...

Problems solved by technology

[0003] In the process of realizing the present invention, the inventors found that there are at least the following problems in the prior art: on the one hand, each production line is equipped with manpower, and the day and night shifts take turns to check whether the glue spots on the product surface are qualified, resulting in high labor costs. At the same time, Human fatigue due to long-term work is prone to misjudgment, which will affect the test results of the product

On the other hand, as the area of ​​glue dots formed by dispensing is getting smaller and smaller, the precision requirements are getting higher and higher, and it is difficult for human eyes to distinguish, which makes it more and more difficult to manually detect whether the glue dots on the surface of the product are qualified.
