Problems solved by technology
Except for the size, the rest of the inspection items are appearance inspection, and the appearance inspection of colloidal products has always been a major problem in the field of automation equipment inspection, because the shape of colloidal products is ever-changing, which affects the accuracy of industrial cameras and the selection of light sources as well as The lighting scheme has very high requirements, and there are often such situations: when two or more light sources are selected, the light sources will interfere with each other, resulting in weakened lighting effects, so it is difficult to use one camera to take care of multiple detection item
[0003] In addition, when detecting high-speed conductive adhesive, the detection speed of the equipment is relatively high, and in general, the camera is detected in a static state, and it is difficult to detect in high-speed motion

Embodiment 1
[0032] A detection method for high-speed conductive adhesive, comprising the following steps:
[0033] (1) Select the most suitable light source according to different testing items. For example, the front of the product needs to detect wrinkled glue, lack of glue, indentation, dirt, and exposed copper. Therefore, two strip light sources need to be installed under the product , a flat light source, and a parallel surface light is installed between the upper surface of the product and the camera lens. In addition, the lens of Keyence HX-500M is selected. This type of lens has the characteristics of large depth of field and high precision. This solution can detect the above detection item; the lower surface of the product needs to detect the size, it needs to be equipped with parallel surface light and the same lens.
[0034] (2) The camera controller uses KEYENCE's CV-290F, which has a fast processing speed and can meet the requirements of product detection in fast motion; the ...

The invention discloses a method for detecting a high-speed conductive adhesive and application thereof. The method comprises the steps of performing visual part light source model selection, detecting the implementation of precise location of products in a high-speed movement state, detecting multiple indexes of the product and stripping unqualified products. The method for detecting the high-speed conductive adhesive is simple to operate, raw materials are easy to obtain, requirements for needed devices are low, the conductive adhesive can be detected at a high speed at a low price, and the detection speed is greatly improved. In addition, according to the method for detecting the high-speed conductive adhesive, mechanical intelligent detection is performed, relevant parameters of the conductive adhesive can be measured accurately, so that whether the conductive adhesive is qualified is determined, and the problem of a low rate of finished products caused by the use of unqualified conductive adhesives can be effectively solved.
Description
technical field [0001] The invention belongs to the field of machinery, and in particular relates to a detection method and application of high-speed conductive glue. Background technique [0002] High-speed conductive adhesive is a colloid product with both front and back sides, because it has many inspection items, including: wrinkled glue, lack of glue, indentation, dirt, exposed copper and size. Except for the size, the rest of the inspection items are appearance inspection, and the appearance inspection of colloidal products has always been a major problem in the field of automation equipment inspection, because the shape of colloidal products is ever-changing, which affects the accuracy of industrial cameras and the selection of light sources as well as The lighting scheme has very high requirements, and there are often such situations: when two or more light sources are selected, the light sources will interfere with each other, resulting in weakened lighting effects,...
