and S206, analyzing whether the capacitor has a fault of a fault type corresponding to the detection station or not according to the acquired image.
Through the steps, the capacitor is controlled to revolve to reach a plurality of detection stations, wherein different detection stations are used for detecting different fault types of the capacitor; when the capacitor is detected on each detection station, the capacitor is controlled to rotate, and image acquisition is carried out on the capacitor; according to the collected images, whether the capacitor has a fault type fault mode corresponding to the detection station or not is analyzed, the capacitor is subjected to all-dimensional image collection, faults of different fault types are detected through the collected images, and the purpose of effectively detecting the appearance fault of the capacitor is achieved, so that the technical effects of improving the detection efficiency and accuracy of the capacitor are achieved, and the technical problem of low efficiency of a capacitor detection method in the related technology is solved.
The capacitor revolution is carried out on the equipment by rotating around a certain central shaft outside the capacitor, and is mainly used for changing the relative position between the capacitor and a plurality of detection stations. The capacitance may be provided on an index plate, and the index plate may be rotated according to a control command to rotate the capacitance provided on the index plate, thereby moving the position of the capacitance with respect to the detection station. The detection stations are multiple, and multiple different detection stations are used for respectively detecting appearance faults of the capacitors with different fault types. The capacitor is subjected to multiple fault detection through the revolution and the multiple detection stations one by one, so that the purpose of effectively detecting the appearance fault of the capacitor is achieved, the technical effects of improving the detection efficiency and accuracy of the capacitor are achieved, and the technical problems of low detection capacity, single detection content and low efficiency of a capacitor detection method in the related technology are solved.
When appearance fault detection is carried out on the capacitor on each detection station, because the capacitor is a three-dimensional object which is usually cylindrical, similar to spherical or ellipsoidal, the appearance fault detection is carried out on the capacitor through the image acquisition device on the detection stations, and when the detection is carried out, the acquisition surfaces of the capacitor and the image acquisition device are limited, so that the image of the whole appearance of the capacitor is difficult to acquire at one time. In order to detect the capacitor more thoroughly and accurately, on each detection station, the capacitor is controlled to rotate according to the requirement of the detected appearance fault of the capacitor, and image acquisition is carried out on a plurality of angles of the capacitor, so that the detection accuracy and the detection efficiency of the capacitor are improved. Optionally, an image acquisition device and a light source are arranged on the detection station; the image acquisition device is used for acquiring images of the capacitors on the detection stations; and/or the light source is used for providing a light source for the capacitor on the detection station.
The rotation of the capacitor can be that the capacitor rotates around a certain central shaft in the capacitor, and the rotation of the capacitor is mainly used for changing and calling the pose of the image detection device which is fixed relative to the position, so that the capacitor can be effectively and perfectly detected on the corresponding detection station. The rotation can rotate the capacitor by virtue of a free arm, and the free arm can comprise a plurality of arm sections with different degrees of freedom so as to control the capacitor clamped at the end part of the free arm to realize the rotation with multiple dimensions.
And analyzing whether the capacitor has a fault of a fault type corresponding to the detection station or not according to the acquired image. For the appearance faults of the capacitors with different fault types, the rotation angles of the capacitors are different, the acquired images of the capacitors are also different, and the processing and analysis of the images are also different. For example, when the capacitance is monitored for deformation, it is only necessary to extract a capacitance profile in an acquired image of the capacitance, determine whether the profile has changed, and determine that the capacitance has deformed when the capacitance profile does not meet the requirement. When the capacitor is printed and detected, only the part of the capacitor with the printed content needs to be subjected to image acquisition, and the printed content in the acquired image is extracted and detected.
Optionally, the plurality of inspection stations includes at least one of: the first detection station is used for detecting whether the appearance of the top surface of the capacitor is complete, the second detection station is used for detecting whether the appearance of the side surface of the capacitor is complete, the third detection station is used for detecting whether the capacitor has integral appearance faults, and the fourth detection station is used for detecting whether the capacitor has deformation.

The failure of the capacitor can be known in detail through the detection result.
Optionally, when the capacitor is detected at each detection station, the capacitor is controlled to rotate, and image acquisition is performed on the capacitor; according to the collected images, whether the faults of the fault types corresponding to the detection stations exist in the capacitor or not is analyzed, and the method comprises the following steps: controlling the capacitor to revolve to a first detection station; acquiring a top surface image of the top surface appearance of the capacitor through a first image acquisition device; and determining whether the appearance of the top surface of the capacitor is good or not according to the top surface image.
The capacitor is controlled to revolve to a first detection station, the appearance of the top surface of the capacitor is detected, and specifically, a top surface image of the appearance of the top surface of the capacitor can be acquired through a first image acquisition device; and determining whether the appearance of the top surface of the capacitor is good or not according to the top surface image. And under the condition that the appearance of the top surface of the capacitor is determined to be intact, the capacitor is controlled to revolve to a second monitoring station, under the condition that the appearance fault of the top surface of the capacitor is determined, the capacitor is put into a feed opening, the capacitor is collected through the feed opening, and the collected fault capacitor is recycled or scrapped.
Optionally, before acquiring the top surface image of the top surface appearance of the capacitor by the first image acquisition device, the method includes: acquiring a pose image of the capacitor through a first image acquisition device; determining the rotation angle of the capacitor according to the acquired pose image, wherein after the capacitor rotates by the rotation angle, the top surface of the capacitor is over against the first image acquisition device; and controlling the rotation angle of the capacitor to enable the top surface of the capacitor to be opposite to the first image acquisition device.
It should be noted that, before the first image capturing device captures the top surface image of the top surface appearance of the capacitor, since the first detection station is the first detection station through which the capacitor passes, the position and orientation of the capacitor cannot be predicted, and of course, a position and orientation correcting device may be provided before the first detection station, so that the top surfaces of all capacitors passing through the position and orientation correcting device can face the first image capturing device of the first detection station. In this embodiment, before the pose of the capacitor is adjusted, an image of the current pose of the capacitor is acquired at the first inspection station, the current pose of the capacitor is determined, and the capacitor is rotated by a rotation device of the capacitor, such as the free arm, so that the top surface of the capacitor faces the first image acquisition device of the first inspection station, so that the first image acquisition device acquires a top surface image. The embodiment adds the pose correction function to the first detection station, avoids the arrangement of a pose correction device, and saves space and cost.
Therefore, the present embodiment includes, before the top surface image of the top surface appearance of the capacitor is acquired by the first image acquisition device: acquiring a pose image of the capacitor through a first image acquisition device; determining the rotation angle of the capacitor according to the acquired pose image, wherein after the capacitor rotates by the rotation angle, the top surface of the capacitor is over against the first image acquisition device; and controlling the rotation angle of the capacitor to enable the top surface of the capacitor to be opposite to the first image acquisition device.
Optionally, when the capacitor is detected at each detection station, the capacitor is controlled to rotate, and image acquisition is performed on the capacitor; according to the collected images, whether the faults of the fault types corresponding to the detection stations exist in the capacitor or not is analyzed, and the method comprises the following steps: controlling the capacitor to revolve to a second detection station; controlling the capacitors to rotate, and acquiring side images of the capacitors through a second image acquisition device; and determining whether the side appearance of the capacitor is good or not according to the plurality of side images.

However, at least four side images need to be detected at the second detection station, so that the side appearance of the capacitor can be accurately detected.
The four side images mean that the time for rotation of the capacitor and the matching of the second image acquisition device is longer, but the speed of the index plate cannot be reduced due to the fact that the index plate bears other capacitors, so that the matching of the capacitor and the second image acquisition device can be divided into two parts, namely, the capacitor is respectively matched with the first image acquisition device and the second image acquisition device on the first sub-station and the second sub-station, and the synchronous detection with other detection stations is realized. Thereby making pipelined capacitive sensing possible.

The four side images can be obtained by directly facing the side of the capacitor to a second image acquisition device of a second detection station after the capacitor is detected from the first detection station and then rotating around the central shaft of the capacitor to display the side of the capacitor rotating for one circle to the second image acquisition device, and the second image acquisition finger can acquire the side of the capacitor at the positions of 0 degree, 90 degrees, 180 degrees and 270 degrees of the rotation of the capacitor to obtain the four side images.
The number of the side images is at least two, and is not limited to a large number, and the observation becomes clearer as the number of the side images increases, but the image processing amount is multiplied accordingly. Moreover, the two side images may cause the side images at the edge portion to deform, which may cause the information recorded in the images to be unclear, so that the embodiment adopts four side images, which not only ensures the definition of the side images and ensures the integrity of the side images bearing information, but also avoids the problems of low processing speed and heavy processing load caused by excessive side images.
