Let’s talk about how to enhance the stability of the automatic riveting machine during riveting?

How to enhance the stability of the automatic riveting machine when riveting? After riveting, the edge size of the rivet fastener needs to be measured, and the contour defects also need to be detected. The edge detection algorithm can be applied to the detection of fastener head size and contour defects, and It allows us to understand the actual effect of detection. In the original input image, we first need to determine the projection rectangle and projection image, and then we need to determine the filtering and edges.

And the difference between the pixels of the two line segments is the pixel size, which gives a good measure of the rivet size by calibrating the actual size.

In the input image, if there is a shadow inside the rivet edge outline, it should be merged.

In fact, the outline of the edge can be determined by the directionality of the grayscale change at the edge to eliminate interference.

Using the dimensional measurement method, the detection of contour defects can be completed. The principle is the same as that of dimensional measurement.

 

The specific detection method is as follows: first you need to determine a projected rectangle, starting from the fastener head, and then measure the size. The projected rectangle is rotated in a fixed circle, and then the size is measured. Each time it is rotated, its angle should be according to the outline. Determine the accuracy required for defect detection. If high rivet accuracy is required, the angle of each rotation should be smaller.

 

When the automatic riveting machine is riveting, the rivets need to have a certain degree of stability. Under the action of riveting, the column rivets are prone to losing stability, causing bending deformation, and even ball jamming, and the bearing rotation is ineffective.

 

The rivets of the automatic riveting machine are relatively flexible when bending in the thickness direction, so the stability of the rivets in the thickness direction needs to be checked.

 

When the automatic riveting machine is riveting, the lower end of the rivet can be fixed, but the upper end can only translate and not rotate. For rivets with a shorter length, their flexibility is less than the flexibility of the corresponding material, so the rivet is a small compliance rod. Once the rivet loses its stable critical stress, It is necessary to check the stability of the pressure rod.

 

If the rivets do not meet the requirements during inspection, it means that the rivets are not stable enough when the automatic riveting machine is riveting. The thickness of the rivets should be increased to improve the stability during riveting.

 

In short, in order to enhance the stability of the automatic riveting machine, you need to pay attention to the thickness and length of the rivets.
