Detailed ways

In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The embodiments of the present invention are some of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Example 1

As shown in Figures 1 and 2, the AC capacitor automatic detection device includes a detection table 20 and a transfer table 10 arranged on one side of the detection table 20. The table surface of the detection table 20 is provided with a first conductive sheet 21 and a second conductive sheet 21. The conductive sheet 22, the first conductive sheet 21 and the second conductive sheet 22 are insulated from each other, the first conductive sheet 21 and the second conductive sheet 22 respectively contact two pins of the capacitor and electrically conduct the capacitor and the detection system, The distance between the two ends of the second conductive sheet 22 is greater than that of the first conductive sheet 21 to accommodate the distance between the terminals of the capacitor.

Based on the above technical solutions, the main technical problems solved by the automatic detection device for AC capacitors of the present invention are that the specifications of AC capacitors are complex and the spacing between terminals is different. The contact distance of traditional automatic detection devices is fixed and cannot match the size of all capacitors. Or manual detection, but the efficiency of manual detection is too low. Therefore, an automatic detection device for AC capacitors is designed. The transfer table 10 is used to transfer the capacitance in real time, and send the capacitor to be detected to the test table 20. The terminal of the capacitor to be detected faces the side of the test table 20. When the capacitor to be detected enters After the detection stage 20, one terminal of the capacitor is in matching contact with the first conductive sheet 21, and the other terminal of the capacitor is in matching contact with the second conductive sheet 22. The first conductive sheet 21 and the second conductive sheet 22 connect the two terminals of the capacitor with the second conductive sheet 22. The detection system is electrically turned on, thereby realizing the performance detection of the capacitor. Since the distance between the two ends of the second conductive sheet 22 is greater than that of the first conductive sheet 21, that is to say, the second conductive sheet 22 is long enough, when one terminal of the capacitor is in matching contact with the first conductive sheet 21, the other terminal of the capacitor A terminal will fall on the top of the second conductive sheet 22 and contact it. Since the second conductive sheet 22 is long enough, it can match terminals of different specifications of capacitors.

It should be noted that the main function of the first conductive sheet 21 and the second conductive sheet 22 is to electrically conduct the terminal of the capacitor to be detected with the detection system, and the detection system actually used to detect the performance of the capacitor can use the detection system of the prior art. system, the wires of the detection system are respectively connected to the first conductive sheet 21 and the second conductive sheet 22 by soldering.

As an embodiment of the above technical solution, as shown in FIG. 4 , the number of the second conductive sheet 22 is one, and the second conductive sheet 22 covers other parts of the detection table 20 except the first conductive sheet 21 . In this way, the span of the second conductive sheet 22 is large enough to meet the matching requirements with the capacitor terminals.

As shown in FIG. 1 , a pressure plate 23 is provided above the detection table 20 , and the pressure plate 23 and the detection table 20 are rotatably connected with the detection table 20 through hinges or hinges. The pressing plate 23 presses and sticks the terminals of the capacitor to be measured on the second conductive sheet 22 and the first conductive sheet 21 by rotating, so as to ensure the smoothness of the detection circuit and the stability of the detection result.

As shown in FIG. 2 , insulating spacers 24 are provided between the first conductive sheet 21 and the second conductive sheet 22 . The insulating spacer 24 is provided to ensure the insulation between the first conductive sheet 21 and the second conductive sheet 22, and to avoid the short circuit phenomenon caused by filling the gap between the first conductive sheet 21 and the second conductive sheet 22 with easily conductive dust. .

As shown in FIG. 2 , the top of the insulating spacer 24 protrudes from the top surface of the first conductive sheet 21 , and the cross-section of the protruding portion of the insulating spacer 24 is arc-shaped or triangular-shaped. When the terminal of the capacitor to be measured is just above the insulating spacer 24, the pressure plate 23 is pressed down. Since the top of the insulating spacer 24 does not have a plane bearing surface, the terminal of the capacitor will slide down along the arc surface or inclined plane and enter the first The conductive sheet 21 or the second conductive sheet 22 .

Example 2

As another embodiment, the difference between this embodiment and Embodiment 1 lies in the structure and quantity of the second conductive sheets 22 .

As shown in FIGS. 1 to 3 , the number of the second conductive sheets 22 is at least two, and the shape and specifications of the second conductive sheets 22 and the first conductive sheets 21 are exactly the same. The second conductive sheets 22 are along the length direction of the detection table 20 Evenly spaced. Such structural features can not only meet the matching requirements with different capacitor terminals, but also design the second conductive sheet 22 and the first conductive sheet 21 to have the same size specification, which can reduce the detection time of the second conductive sheet 22 and the first conductive sheet 21. The detection error caused by the size difference improves the detection accuracy. Based on the technical solution of this embodiment, each second conductive sheet 22 is connected with a branched conductive wire, the branched conductive wire connects the second conductive sheet 22 in parallel, and the ends of the branched conductive wire are connected to the main conductive wire, so that when detecting , the other terminal of the capacitor will only contact one of the second conductive sheets 22 and finally complete the detection.

As shown in FIG. 2 , insulating spacers 24 are also arranged between the adjacent second conductive sheets 22 , also to ensure insulation.

In addition, the shape and structural features of the insulating spacers 24 in this embodiment are exactly the same as those in Embodiment 1, so as to achieve the same technical effect.

Example 3

This embodiment is further improved on the basis of Embodiment 1 and Embodiment 2, so as to improve the automatic control function of the automatic AC capacitor detection device.

The AC capacitor automatic detection device further includes a control system, and the control system includes a detection unit 30, an information processing unit and a driving unit.

The detection unit 30 is used to detect whether the terminal enters into the detection station 20 and form detection signals "0" and "1";

The information processing unit is used to receive the detection signal generated by the detection unit 30 and convert it into control signals "A" and "B" at the same time;

The driving unit is directly controlled by the control signal provided by the information processing unit to perform control operations.

As mentioned above, the detection signals "0" and "1" formed by the detection unit 30 respectively indicate that the pin is not detected and that the pin is detected; the control signals "A" and "B" generated by the information processing unit respectively indicate that the driving unit makes Control actions and do the opposite of control actions.

The detection unit 30 is a grating sensor or an infrared sensor, both of which are sensing devices in the prior art, and the detection unit 30 is arranged on the detection table 20 near one end of the first conductive sheet 21 , and the purpose of this is to directly detect whether there is a capacitor entering the In the testing stage 20, when a capacitor to be tested enters the testing stage 20, the testing unit 30 will form a detection signal "1" when it detects the edge of the pin, and maintain the detection signal "0" at other times.

The information processing unit is designed to receive the detection signals "1" and "0", and at the same time distinguish two consecutive detection signals "1" to form different control signals "A" and "B". That is, after any two consecutive detection signals "1" enter the information processing unit, the information processing unit needs to filter or convert the first detection signal "1" into a detection signal "0", and generate a control signal "A" at the same time. The information processing unit needs to convert the second detection signal "1" into a control signal "B". In this embodiment, the control signal "A" is normal control, that is, the AC capacitor automatic detection device maintains the original state, and the control signal "A" B" is the detection state, that is, the transfer stage 10 stops the transfer to keep the capacitor position fixed, and at the same time, the pressure plate 23 is pressed down to press the terminals of the capacitor to be measured against the second conductive sheet 22 and the first conductive sheet 21 to complete the capacitance adjustment. detection.

The detection state duration of the control signal "B" is preferably 2-5s, to ensure that the pressing plate 23 has enough time to press the terminal, and the detection system can successfully complete the detection. After the duration of the control signal "B" ends, the information processing unit The received detection signal "0" is formed into a control signal "A" to control the AC capacitor automatic detection device to maintain the original state, that is, the pressure plate 23 is lifted, and the transfer table 10 starts to work to transfer the next capacitor to be measured to the test table 20. , and send the last capacitor that has been tested to the test stage 20 .

It should be noted that the transfer table 10 is a transfer table in the prior art, and the transfer belt is driven by the transfer roller to complete the transfer, and the motor is driven to provide power, and the motor is one of the driving units; Cylinder control, the cylinder is also one of the drive units. Since the driving structure of the transfer table 10 and the pressing plate 23 is not an innovative point of the present invention, it will not be described in detail here.

Combined with the above description, as shown in Figures 3 and 4, the working process of the AC capacitor automatic detection device is as follows: the motor drives the transmission table 10 to work to send the capacitor to be measured to the detection table 20, and the conveying direction is shown by the arrow in the figure. When the capacitor is close to the first conductive sheet 21 on the detection table 20, the detection unit 30 detects the first terminal of the capacitor, forms a detection signal "1" and converts it into a normal control signal "A" through the information processing unit. At this time, the transmission table 10 Continue to work to send the capacitor to the detection table 20 until the detection unit 30 detects the second terminal of the capacitor, forming a detection signal "1" and transmitting it to the information processing unit. For two consecutive detection signals "1", the information processing unit will The second detection signal "1" is converted into a detection state control signal "B", so that the transfer stage 10 stops, so that the second terminal of the capacitor that enters the detection stage 20 will fall on the first conductive sheet 21. The first terminal of the capacitor entering the test stage 20 will fall on the second conductive sheet 22, and the detection state control signal "B" simultaneously controls the pressing plate 23 to press down so that the terminal of the capacitor is connected to the first conductive sheet 21 and the second conductive sheet. 22 fit, and the detection is successfully completed; after the detection is completed, the duration of the detection state control signal "B" ends, because the capacitor enters the detection table 20, the detection signal of the detection unit 30 will remain "0", and the information processing unit will receive the detection The detection signal "0" of the unit 30 is converted into the normal control signal "A", the pressure plate 23 is lifted, the transfer table 10 continues to work, and the next capacitor to be tested is transferred to the test table 20, and the last completed test is sent. The capacitor is sent out to the detection table 20, and repeating the process, the technical effect of the automatic control function can be realized.
