Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of 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, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, belong to the protection scope of the present invention.
Example 1
As shown in fig. 1 and 2, the full-automatic detection device for the ac capacitor comprises a detection platform 20 and a conveying platform 10 arranged on one side of the detection platform 20, wherein a first conducting plate 21 and a second conducting plate 22 are arranged on a table top of the detection platform 20, the first conducting plate 21 and the second conducting plate 22 are insulated from each other, the first conducting plate 21 and the second conducting plate 22 respectively contact two pins of the capacitor and electrically connect the capacitor with a detection system, and the distance between two end parts of the second conducting plate 22 is greater than the terminal distance of the first conducting plate 21 to adapt to the capacitor.
Based on the technical scheme, the full-automatic detection device for the alternating current capacitor mainly solves the technical problems that the alternating current capacitor is complex in specification and different in terminal spacing, the contact distance of the traditional automatic detection device is fixed and cannot be matched with the sizes of all capacitors, or manual detection is carried out, but the manual detection efficiency is too low. Therefore, the full-automatic detection device for the alternating-current capacitor is designed, the conveying table 10 is used for conveying the capacitor in real time, the capacitor to be detected is conveyed to the detection table 20, the terminal of the capacitor to be detected faces one side of the detection table 20, when the capacitor to be detected enters the detection table 20, one terminal of the capacitor is in matched contact with the first conducting strip 21, the other terminal of the capacitor is in matched contact with the second conducting strip 22, the first conducting strip 21 and the second conducting strip 22 conduct two terminals of the capacitor with the electrical property of the detection system, and therefore performance detection of the capacitor is achieved. Since the distance between the two ends of the second conductive plate 22 is greater than that of the first conductive plate 21, that is, the second conductive plate 22 is long enough, when one terminal of the capacitor is matched with the first conductive plate 21, the other terminal of the capacitor falls above the second conductive plate 22 to contact with the second conductive plate, and since the second conductive plate 22 is long enough, the terminals of capacitors with different specifications can be matched.
It should be noted that the first conductive sheet 21 and the second conductive sheet 22 mainly function to electrically connect the terminal of the capacitor to be detected with the detection system, and the detection system actually used for detecting the capacitive performance may adopt the detection system of the prior art, and the wires of the detection system are respectively connected with the first conductive sheet 21 and the second conductive sheet 22 by soldering.
As an example of the above technical solution, as shown in fig. 4, the number of the second conductive sheets 22 is one, and the second conductive sheets 22 cover the other parts of the table top of the detection table 20 except the first conductive sheet 21. Thus, the span of the second conductive sheet 22 is large enough to meet the matching requirement with the capacitor terminal.
As shown in fig. 1, a pressing plate 23 is disposed above the inspection table 20, and the pressing plate 23 is rotatably connected to the inspection table 20 by a hinge or a hinge. The pressing plate 23 presses and attaches the terminal of the capacitor to be tested to the second conducting plate 22 and the first conducting plate 21 by rotating, so as to ensure the smoothness of the detection loop and ensure the stability of the detection result.
As shown in fig. 2, an insulating spacer 24 is disposed between the first conductive sheet 21 and the second conductive sheet 22. The insulating spacer 24 is provided to ensure insulation between the first conductive sheet 21 and the second conductive sheet 22, and prevent a short circuit phenomenon caused by filling easily conductive dust in a gap between the first conductive sheet 21 and the second conductive sheet 22.
As shown in fig. 2, the top of the insulating division bar 24 protrudes from the top surface of the first conductive sheet 21, and the cross section of the protruding portion of the insulating division bar 24 is in an arc shape or a triangular shape with a large top and a small bottom. When the terminal of the capacitor to be tested is located right above the insulating division bar 24, the terminal is pressed down by the pressing plate 23, and the terminal of the capacitor slides down along the arc surface or the inclined surface to enter the first conducting strip 21 or the second conducting strip 22 because the top of the insulating division bar 24 has no plane bearing surface.
Example 2
As another embodiment, the present embodiment is different from embodiment 1 in the structure and the number of the second conductive sheets 22.
As shown in fig. 1 to 3, the number of the second conductive sheets 22 is at least two, and the shape and specification of the second conductive sheets 22 are completely the same as those of the first conductive sheets 21, and the second conductive sheets 22 are uniformly distributed along the length direction of the inspection table 20 at intervals. Due to the structural characteristics, the matching requirements of different capacitor terminals can be met, the second conducting strip 22 and the first conducting strip 21 are designed to be in the same size specification, the detection error caused by the size difference between the second conducting strip 22 and the first conducting strip 21 during detection can be reduced, and the detection accuracy is improved. Based on the technical solution of this embodiment, each second conductive sheet 22 is connected with a branch conductive wire, the branch conductive wire connects the second conductive sheets 22 in parallel, and the ends of the branch conductive wires are connected with the total conductive wire, so that during detection, the other terminal of the capacitor only contacts one of the second conductive sheets 22 to finally complete the detection.
As shown in fig. 2, an insulating spacer 24 is also provided between the adjacent second conductive sheets 22, similarly to ensure insulation.
In addition, the shape and structure characteristics of the insulating division bar 24 in this embodiment are exactly the same as those in embodiment 1, so as to achieve the same technical effects.
Example 3
The present embodiment is further improved on the basis of embodiments 1 and 2 to improve the automatic control function of the full-automatic detection device for ac capacitors.
The full-automatic detection device for the alternating current capacitor further comprises a control system, and the control system comprises a detection unit 30, an information processing unit and a driving unit.
The detection unit 30 is used for detecting whether the terminal is entered into the detection stage 20 and forming detection signals "0" and "1";
the information processing unit is used for receiving the detection signal generated by the detection unit 30 and converting the detection signal into control signals 'A' and 'B';
the driving unit is directly controlled by the control signal provided by the information processing unit to perform control operation.
As described above, the detection signals "0" and "1" formed by the detection unit 30 indicate that no pin is detected and that a pin is detected, respectively; the control signals "a" and "B" generated by the information processing unit indicate that the driving unit makes a control-by-control operation and an operation opposite to the control-by-control operation, respectively.
The detection unit 30 is a grating sensor or an infrared sensor, and is a sensing device in the prior art, and the detection unit 30 is disposed at one end of the detection table 20 close to the first conductive sheet 21, so as to directly detect whether a capacitor enters the detection table 20, when a capacitor to be detected enters the detection table 20, the detection unit 30 detects that the edge of the pin forms a detection signal "1", and the detection signal "0" is maintained at other times.
The information processing unit is intended to receive the detection signals "1" and "0" while differentiating two consecutive detection signals "1" into 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 simultaneously generate a control signal "a", and in addition, 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 full-automatic detection device for the ac capacitor maintains the original state, and the control signal "B" is a detection state, that is, the transmission table 10 stops transmitting to keep the position of the capacitor fixed, and simultaneously, the pressing plate 23 is pressed down to press and attach the terminal of the capacitor to be detected to the second conductive plate 22 and the first conductive plate 21 to complete the detection of the capacitor.
The detection state duration time of the control signal 'B' is preferably 2-5 s, so that the pressing plate 23 has enough time to press the terminal, meanwhile, the detection system can complete detection smoothly, after the duration time of the control signal 'B' is finished, the information processing unit forms the received detection signal '0' into a control signal 'A' to control the full-automatic detection device of the alternating current capacitor to maintain the original state, namely, the pressing plate 23 is lifted, the conveying table 10 starts to work to convey the next capacitor to be detected to the detection table 20, and the last capacitor to be detected is conveyed out of the detection table 20.
It should be noted that the conveying table 10 is a conveying table in the prior art, the conveying belt is driven by the conveying roller to complete conveying, and power is provided by driving of a motor, which is one of the driving units; in addition, the raising and lowering of the platen 23 may be controlled by an air cylinder, which is also one of the driving 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.
With reference to the above description, as shown in fig. 3 and 4, the operation process of the ac capacitor full-automatic detection apparatus is as follows: the motor drives the transmission platform 10 to work to send the capacitor to be detected to the detection platform 20, the transmission direction is as shown by the arrow in the figure, when the capacitor approaches the first conducting strip 21 on the detection platform 20, the detection unit 30 detects the first terminal of the capacitor to form a detection signal "1" and converts the detection signal "1" into a normal state control signal "a" through the information processing unit, at this time, the transmission platform 10 continues to work to send the capacitor to the detection platform 20 until the detection unit 30 detects the second terminal of the capacitor to form a detection signal "1" and transmits the detection signal "1" to the information processing unit, for two continuous detection signals "1", the information processing unit converts the second detection signal "1" into a detection state control signal "B", so that the transmission platform 10 stops, thus the second terminal of the capacitor entering the detection platform 20 will fall onto the first conducting strip 21, the first terminal of the capacitor entering the detection platform 20 will fall onto the second conducting strip 22, the detection state control signal 'B' simultaneously controls the pressing plate 23 to press down to enable the capacitor terminal to be attached to the first conducting plate 21 and the second conducting plate 22, and detection is completed smoothly; after the detection is completed, the duration time of the detection state control signal 'B' is over, because the capacitor enters the detection table 20, the detection signal of the detection unit 30 will maintain '0', the information processing unit will receive the detection signal '0' of the detection unit 30 and convert it into the normal state control signal 'a', the pressing plate 23 is lifted up, the transmission table 10 continues to work, the next capacitor to be detected is transmitted to the detection table 20, and the last capacitor which has been detected is transmitted out of the detection table 20, and the above operation is repeated, so that the technical effect of the automatic control function can be realized.
