Description
Technical Field
The invention relates to the technical field of dispensing detection, in particular to an on-line detection system and method for a mobile phone shell glue line.
Background
After dispensing is performed on the frame of the mobile phone shell, in order to prevent abnormal dispensing (too much or too little dispensing) from causing abnormal conditions after the screen is attached, the dispensing quality needs to be detected so as to ensure the product quality.
The existing main detection modes comprise two types, one is off-line manual detection, and the other is on-line camera shooting detection.
However, the following disadvantages exist for off-line manual detection: 1. offline shutdown detection is required to ensure accuracy, resulting in low efficiency; 2. the surface and the side surface of the product can be damaged by multiple times of transportation; 3. the reliability and accuracy are low due to factors such as semitransparent glue paths, eye fatigue, inconsistent judgment of glue path corner parts and the like. For on-line camera photographing detection, the misjudgment rate is higher due to the factors such as the semitransparent glue path, the conical light path of the camera and the like.
Disclosure of Invention
In view of the defects in the prior art, an object of the present invention is to provide an on-line detection system for a mobile phone shell glue line, which has the advantages of improving detection efficiency, reliability and accuracy.
In order to achieve the purpose, the invention provides the following technical scheme:
an on-line detection system for a mobile phone casing adhesive circuit, comprising:
a platen;
a four-axis linkage mechanism carried on the platen;
the 3D vision sensor is borne on the four-axis linkage mechanism; and the number of the first and second groups,
and the conveying platform is matched with the 3D vision sensor and is provided with a dispensing table for bearing the mobile phone shell.
Furthermore, the four-axis linkage mechanism comprises an X-axis moving mechanism, a Y-axis moving mechanism, a Z-axis moving mechanism and a U-axis moving mechanism.
Another object of the present invention is to provide an on-line detection method for a mobile phone casing adhesive circuit, which has the advantages of improving detection efficiency, reliability and accuracy.
In order to achieve the purpose, the invention provides the following technical scheme:
an online detection method for a mobile phone shell rubber circuit comprises the following steps:
s100, before dispensing of the mobile phone shell, measuring a height difference H1 between a shell side (the highest horizontal position of the mobile phone shell relative to a dispensing table) and the dispensing table by using an online detection system of a mobile phone shell glue line;
s200, after dispensing of the mobile phone shell, measuring a height difference H2 between a glue line and a shell edge by using an online detection system of a mobile phone shell glue line;
and S300, measuring to obtain the height H3 and the width W1 of the glue line.
Further, in step S200, if the glue dispensing table can be identified, the height H3 of the glue line can be directly measured and obtained with the glue dispensing table as a reference.
Further, in step S300, the height H3 of the glue line is H1-H2.
Further, in step S300, the width of the glue line is measured by taking the shell side as a horizontal line, moving the height H1 downward to make a cross-sectional line, and obtaining two intersections of the cross-sectional line and the glue line, i.e., the width W1 of the glue line can be measured.
In conclusion, the invention has the following beneficial effects:
1. after the width and the height of the glue line are measured, the ratio of the height to the width of the glue line is calculated, and then the glue treading (too little glue dispensing) or glue overflowing (too much glue dispensing) of the glue line can be judged, so that the product quality can be ensured;
2. because the quality control of the height difference between the shell edge and the dispensing table is loose, and the variation of the value H1 is large, the height H3 of the glue line and the width W1 of the glue line are required to be accurately obtained, the height value H1 must be accurately measured, H1 is measured before dispensing, and H2 is measured after dispensing, so that the reliability and the accuracy of detection can be improved;
3. the online detection can be realized without stopping, the efficiency is higher, and the damage to the product caused by multiple times of conveying is reduced;
4. the intelligent 3D vision sensor is adopted for processing, so that the misjudgment rate caused by eye fatigue is reduced, and the reliability is greatly improved;
5. the data processing can generate the height, the width and the ratio of the glue line, realize the data tracking of the production line body and effectively track each parameter of the production flow;
6. the compatibility is high, and the detection and tracking of multiple products can be realized.
