[0002] A capacitor is composed of two conductors close to each other with a non-conductive insulating medium in between. When a voltage is applied between the two plates of a capacitor, the capacitor will store charge. The capacitance of a capacitor is numerically equal to the ratio of the charge on one conductive plate to the voltage between the two plates. The basic unit of capacitance of a capacitor is farad (F). In circuit diagrams, the letter C is usually used to represent capacitor components.

[0003] Capacitors play an important role in tuning, bypassing, coupling, filtering and other circuits. They are used in the tuning circuit of transistor radios, as well as in the coupling circuit and bypass circuit of color TVs.

The first belt conveyor 1 is started and stopped by a controller (not shown in the figure). The feeding device is used to feed the test bench 2. The capacitor on the test bench 2 is transported by the first belt conveyor 1. There are several test benches 2 and they are distributed along the conveying direction of the first belt conveyor 1. A connecting table 3 is rotatably installed between adjacent test benches 2. The rotating shaft of the connecting table 3 is located on the test bench 2 in front or behind the conveying direction. An A cylinder 4 is installed at the bottom of the connecting table 3. The A cylinder 4 is used to disconnect the connection between adjacent test benches 2. A plurality of B cylinders 5 corresponding to the test bench 2 are installed on the frame of the first belt conveyor 1. A detection module is installed on the piston rod of the B cylinder 5. The detection module is used to press the capacitor on the test bench 2. The test is carried out on the electrode plate, the detection module is electrically connected to the controller, and a photoelectric sensor (not shown in the figure) is installed next to the B cylinder 5. After the photoelectric sensor detects the capacitance, it sends a signal to the controller, stops the first belt conveyor 1 through the controller, and then starts the B cylinder 5. After the test is completed, the first belt conveyor 1 is restarted through the controller. At the same time, the controller analyzes whether the A cylinder 4 is started according to the result of the test module. The test process is as follows: After the test bench 2 is loaded through the loading device, the capacitor to be tested is sent to the test module for testing through the first belt conveyor 1. Qualified products continue to flow to the test module of the next project for testing, while unqualified products are disconnected from the two test benches 2 through the connecting table 3, so that the unqualified products fall under the test bench 2 to complete the sorting. The work efficiency is high and the labor intensity of workers is low. At the same time, unqualified products of different projects are collected and processed in a centralized manner, which avoids subsequent classification, saves labor and reduces production costs.

[0023] In this embodiment, if Figure 1 and Figure 3 As shown, a slope is provided at the end of the test bench 2 near the feeding device, and the slope is used to temporarily store the capacitor delivered to the test bench 2 by the feeding device. A plurality of evenly distributed first push plates 6 are fixed on the belt of the first belt conveyor 1 along the conveying direction, and the first push plates 6 are used to push the capacitor on the slope toward the detection module, and the capacitor is temporarily stored by the slope while being positioned at the initial position, so as to avoid the capacitor rolling and causing an inaccurate initial position, which may cause the first push plate 6 to press on the capacitor and cause damage when it rotates to the connection point.

[0024] In this embodiment, if Figure 1As shown, the feeding device includes a second belt conveyor 7, a linear module 8 and an automatic feeding vibration disk 9. There are N second belt conveyors 7 and N test lines, where N is an integer not less than two. Each second belt conveyor 7 is installed at the end of a corresponding test line. The linear module 8 and the automatic feeding vibration disk 9 are both installed at the end of the second belt conveyor 7. The conveying directions between the linear module 8 and the second belt conveyor 7 are perpendicular to each other. A third belt conveyor 10 is installed on the slider of the linear module 8. The conveying directions of the third belt conveyor 10 and the second belt conveyor 7 are parallel to each other. The third belt conveyor 10 is used to deliver the capacitance conveyed by the automatic feeding vibration disk 9 to the corresponding second belt conveyor 7. The number of test lines can be increased or decreased according to actual production conditions, with high flexibility and strong on-site adaptability.

[0025] In this embodiment, if Figure 1 and Figure 2 As shown, a skirt 11 is provided on the belt of the first belt conveyor 1. There are two skirts 11 and they are respectively located on both sides of the first push plate 6. The skirt 11 is used to prevent the capacitor on the first belt conveyor 1 from sliding outward. The skirt 11 limits the lateral movement of the capacitor during the conveying process, so that the detection module on the side of the first belt conveyor 1 is accurately pressed on the plate of the capacitor for testing, avoiding poor contact affecting the accuracy of the test results.

[0026] In this embodiment, if Figure 3 and Figure 4 As shown, a plurality of evenly distributed second push plates 12 are fixed on the belt of the second belt conveyor 7 along the conveying direction, and a plurality of evenly distributed third push plates 13 are fixed on the belt of the third belt conveyor 10 along the conveying direction. A notch is provided on the second push plate 12, and the notch is used for passing the third push plate 13 to avoid interference between the second and third belt conveyors at the connection due to the push plates, thereby affecting the transmission of capacitors.

[0027] In this embodiment, if Figure 1 As shown, transparent acrylic plates are mounted on the frames of the second belt conveyor 7 and the third belt conveyor 10, and gaps are set between the second push plate 12 and the transparent acrylic plate, and between the third push plate 13 and the transparent acrylic plate. The gap is no more than one millimeter, which is convenient for observing the capacitor transmission situation and can limit the capacitor to avoid stacking and affect the subsequent loading of the test bench 2.

[0028] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
