The working process of the whole foot equipment of the present invention is as follows:

The whole-leg capacitor (3) is arranged in the feeding chute (2). Since the feeding chute (2) is installed obliquely, under the action of gravity, the whole-leg capacitor (3) falls into the distribution chute of the first station ; At this moment, the stepper motor (26) drives the material distribution tray (5) to rotate until the whole foot capacitance (3) is aligned with the first station working groove, and the first blowing pipe (4) blows air so that the whole foot The capacitor (3) is subjected to forward thrust and bias force, and the bias force makes the capacitor (3) to rotate under the action of the limit piece (7). The station material distribution chute moves to the first station working chute. The stepping motor (26) drives the working disk (6) to rotate, and the capacitor (3) to be processed is sent to the second station of the working disk (6), that is, the leg station, and the next capacitor (3) to be processed is in place.

When the whole-foot capacitor (3) arrives at the whole-foot station, when the pins of the whole-foot capacitor (3) are placed in the groove (43), the second cylinder (30) works, and the mechanical fingers (33) are closed. The first cylinder (28) works, and the piston rod of the first cylinder (28) stretches out to drive the connecting rod (29) to move upward, thereby driving the mechanical clamp finger (33) to move upward. Due to the restriction of the groove (43), the capacitor pin is Straighten outwards from the root, when the stroke of the first cylinder (28) is maximum, the second cylinder (30) works in reverse, the mechanical gripper (33) opens, the first cylinder (28) works in reverse, the mechanical gripper ( 33) Return to the original position; at the same time, the working disc (6) rotates, and the whole-foot capacitor is sent to the visual inspection station, and the next whole-foot capacitor (3) is sent to the whole-foot station.

The image acquisition device (10) collects the image of the capacitor pin located at the visual inspection station, and processes the image of the capacitor pin to judge whether the whole capacitor is a qualified product. If judged as a qualified product, the air compressor (16) works, and the second air blowing pipe (25) blows, and under the baffle plate effect, the qualified capacitor falls to the qualified product conveyor belt (14). If it is judged as unqualified product, the working disk (6) rotates, the capacitor is transferred to the next station, that is, the recovery station, the air compressor (16) works, the third blowing pipe (25) blows air, and under the action of the baffle , the unqualified capacitor falls to the unqualified product recovery belt (9) and reclaims.

Judging whether the whole-foot capacitor is a qualified product according to the image of the capacitor pin can be automatically carried out by a computer program, and further includes steps:

(1) Image preprocessing:

When acquiring images, due to factors such as cameras and light sources, the acquired images may not be able to fully present all the information of the capacitor pins, so image preprocessing is required to improve image quality. The image preprocessing of the present invention mainly includes image smoothing and image sharpening. In the specific implementation, image smoothing uses median filter to effectively suppress noise. The basic principle is to replace the pixel value of a certain point in the image with the median value of the pixel values of all neighboring points of the point, thereby eliminating isolated noise points. Since image smoothing often leads to blurred image boundaries and contours, in order to reduce such adverse effects, the Sobel differential operator is used for image sharpening in the specific implementation to effectively enhance the edges or gray-scale jump parts and make the image clear.

(2) ROI selection:

In the specific implementation, a rectangular region of interest (ROI, region of interest) is used, the ROI region is manually selected, and the ROI sub-image is extracted from the preprocessed image as the object of subsequent image processing and analysis. Extracting ROI sub-images can avoid useless search and interference of non-detection target areas in the whole image, thereby improving image detection efficiency and calculation accuracy.

(3) Threshold segmentation:

Based on the pixel value of the original image, the ROI sub-image is thresholded to quickly and effectively separate the end face of the capacitor pin and the background. The gray mean value of the ROI sub-image is used as the initial threshold T _i of threshold segmentation, and then the threshold is adjusted according to the following steps until a given criterion is met.

(a) Use the current threshold T _i to divide the ROI sub-image into regions R ₁ and R ₂ , and calculate the gray mean values μ ₁ and μ ₂ of the regions R ₁ and R ₂ respectively:

Among them, i represents the gray value of the pixel, and n _i represents the number of pixels with the gray value i.

(b) Adjust the threshold according to formula (3):

(c) With the threshold T _i+1 as the current threshold, repeat steps (a) and (b) until T _i+1 -T _i <ε, where ε is a given convergence value, usually 0.02-0.05.

(4) Mathematical Morphological Operation:

Since the end face of the capacitor pin is not completely flat, there are some isolated point noises and small holes in the connected area in the image after threshold segmentation, which increases the difficulty of subsequent measurement of the end face parameters of the pin. Therefore, the present invention adopts the morphological opening operation to smooth the boundary of the end surface of the capacitor pin while maintaining the original shape of the end surface of the capacitor pin. Among them, the morphological opening operation is completed by using two basic morphological operations of erosion first and then dilation.

(5) Judging whether it is qualified:

Based on the image after the mathematical morphology operation, measure the area of the end face of the capacitor pin and the distance between the centroids of the end faces of the two pins, and compare it with the preset standard index of the capacitor pin. If the area of the end face of the capacitor pin and the distance between the centroids of the two end faces If they all fall within the standard index range of the capacitance pin, it is a qualified product; otherwise, it is unqualified.

The above is only the specific implementation of the invention, and the above illustrations do not limit the essence of the present invention. Those of ordinary skill in the art can modify or deform the above specific implementation after reading this specification, without depart from the spirit and scope of the invention.
