Background

The capacitor is an electric element for storing electric quantity and electric energy (potential energy), which is widely used, and is composed of two conductors (polar plates) with a layer of non-conductive insulating medium sandwiched therebetween, when voltage is applied between the two polar plates of the capacitor, the capacitor stores electric charge, and the capacitor plays an important role in circuits such as tuning, bypass, coupling and filtering, so that the capacitor is widely used in various electric products. In the production and processing process of the capacitor, a metal wire is required to be used as a pin of the capacitor, and some types of capacitors have requirements on the distance between two pins, such as the distance between the two pins is required to be not smaller than a certain specific value, so that after the capacitor is produced, a capacitor product is required to be detected, and the distance between the two pins is measured so as to ensure that the distance between the two pins can meet the design requirements. In the conventional production process, the measurement of the distance between two pins of a capacitor is generally performed manually, and a staff member uses a measuring tape to measure the distance between two pins of the capacitor. With the development of technology, there is a way to measure the distance between the pins of the capacitor by using machine vision, for example, in a method for measuring and sorting the distance between the pins of the capacitor based on machine vision disclosed in patent publication No. CN114798474a, which discloses that after the capacitor image is collected, the distance between the pins of the metal is calculated according to the spatial resolution of the image, but the cost of machine vision is higher, in the detection process, if the position and the angle deviation of the capacitor position occur during the image collection, the accuracy of detection is easily affected, especially when detecting products with different specifications and shapes, new recognition algorithms need to be modified again or even developed again for specific products, further increasing the production cost, and when small-batch production is performed, the cost is too high to bear.

The measuring piece 233 is connected with the swinging bracket 231 through a screw, so that the installation position can be adjusted, and capacitors with different pitches can be flexibly adapted. Since the positions of the two measuring pieces 233 are adjustable, the distance between the two measuring pieces 233 can be adjusted according to the detected capacitor, and since the distance between the two measuring pieces 233 is fixed, the two pins of the capacitor can be determined as unqualified as long as the two pins of the capacitor are respectively conducted with the two measuring pieces 233, and the detection accuracy is high and the speed is high. Then, the test can be started, the pushing component 27 pushes the first measuring component 23 and the second measuring component 24 in the initial state, so that the measuring component 233 of the first measuring component 23 and the measuring component 233 of the second measuring component 24 are close to each other, the turntable mechanism 3 moves the capacitor to a position corresponding to the measuring component 233, at this time, the two measuring components 233 are located between two pins of the capacitor, then the pushing component 27 removes pushing force, the two measuring components 233 are far away from each other and are close to two pins of the capacitor respectively, if the two measuring components 233 are in contact conduction with the corresponding pins, the gap is too small, and the capacitor is judged to be defective, otherwise, the capacitor is qualified.
