Detailed implementation manner

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0034] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0035] Embodiment 1:

[0036] Referring to Figures 1-8 , a device for detecting the anti-high-frequency interference performance of a ceramic capacitor, including a conveyor 1 and a mounting frame 2 fixed on its side wall. A bearing plate 21 is fixedly connected to the mounting frame 2, and the top of the bearing plate 21 is in contact with the upper belt of the conveyor 1. It further includes: a lifting platform 3, on which a detector group 4 is fixedly connected. Among them, mounting plates 31 are fixedly connected to both sides of the bearing plate 21. An electric push rod 32 is fixedly connected to the top of one mounting plate 31, and the lifting platform 3 is fixed to the top of the telescopic end of the electric push rod 32. Two guide rods are fixedly connected to the other mounting plate 31, and the lifting platform 3 is sleeved on the two guide rods, so as to use the guide rods to realize the guiding and limiting of the up and down sliding of the lifting platform 3. A detection part for detecting the capacitor is arranged on the lifting platform 3; a positioning component, which is arranged on the mounting plate 31 and is used for positioning the capacitor that moves to the lower part of the lifting platform 3 on the conveyor 1.

[0037] It should be noted that the detector group 4 specifically includes an LCR tester and a network analyzer. The LCR tester is used to measure the parameters of basic components such as the inductance, capacitance, and resistance of capacitors; the network analyzer is a standard tool for measuring the complex scattering parameters of components in a radio frequency circuit, and it can accurately measure the frequency response of capacitors, including impedance and phase changes; both of the above belong to the category of existing technologies, and the specific principles will not be elaborated here.

[0038] Referring to Figures 4-8 , wherein, the detection part includes two groups of symmetrically arranged detection cylinders 5, the two groups of detection cylinders 5 are respectively rotatably connected to both sides of the bottom of the lifting platform 3, an electricity connection groove 51 is opened in the upper part of the inner cavity of the detection cylinder 5, a plug-in groove 52 is opened in the lower part of the inner cavity of the detection cylinder 5, the plug-in groove 52 is communicated with the electricity connection groove 51, a contact plate 53 and a linkage plate 531 are slidably connected in the electricity connection groove 51, a first spring 532 is fixedly connected between the top of the contact plate 53 and the bottom of the linkage plate 531, a wire conduit 533 is fixedly connected to the top of the contact plate 53, the wire conduit 533 penetrates upward through the detection cylinder 5 and is rotatably connected to it, the other end of the wire conduit 533 is fixedly connected to the side wall of the detector group 4, and a clamping part that closely adheres to the outer wall of the capacitor's electricity connection end is arranged at the bottom of the contact plate 53; the clamping part includes an electrode plate 54, a plurality of groups of clamping grooves 541 are equidistantly opened at the bottom of the contact plate 53, the electrode plate 54 is slidably connected in the clamping grooves 541, a second spring 542 is fixedly connected between the side wall of the electrode plate 54 and the inner wall of the clamping groove 541, and the bottom of the electrode plate 54 is provided with an arc chamfer.

[0039] Through the setting of the above structure, during the downward movement of the lifting platform 3, the wiring end of the ceramic capacitor is inserted into the detection cylinder 5, and finally the wiring end will be inserted to the bottom of the contact plate 53. Under the pressure continuously applied downward by the lifting platform 3, the wiring end squeezes the bottom arc chamfer of the electrode plate 54, causing the electrode plate 54 to slide towards the side that compresses the second spring 542. When the wiring end is completely inserted into the cavity of the contact plate 53, under the rebounding action of the second spring 542, the electrode plate 54 is closely attached to the outer wall of the wiring end, achieving better electrical conduction. Moreover, under the rebounding action of the first spring 532, vertical clamping and fixing of the ceramic capacitor are also achieved, effectively ensuring the stability of the ceramic capacitor during the detection process.

[0040] Referring to Figures 6-8 , wherein, a grinding piece 55 is fixedly connected to the inner wall of the plug-in groove 52, a first motor 56 is fixedly connected to the top of the lifting platform 3, the output shaft of the first motor 56 penetrates to the lower part of the lifting platform 3 and is fixedly connected with a driving gear 561, and linkage gears 57 are fixedly connected to the upper parts of the outer walls of the two detection cylinders 5, and the two groups of linkage gears 57 are respectively meshed with the driving gear 561 from both sides.

[0041] By setting up the above structure, the first motor 56 is turned on. Through the meshing relationship between the linkage gear 57 and the driving gear 561, the detection cylinder 5 is driven to rotate. In this way, the wiring ends of the ceramic capacitors continuously inserted into the detection cylinder 5 are polished by the polishing piece 55, removing the oxide layer and dirt on the outer wall of the wiring ends of the ceramic capacitors, ensuring good conductivity and effectively improving the measurement accuracy at the same time.

[0042] In addition, when the detection cylinder 5 rotates, the wire conduit 533, the contact plate 53, the linkage plate 531, and the second spring 542 are all in a relatively stationary state. That is to say, the above structure does not rotate with the detection cylinder 5, which is convenient for arranging the circuits.

[0043] Refer to Figures 5-8 , in which, dust extraction rings 6 are rotatably connected to the outer walls of the two groups of detection cylinders 5. An air extraction cylinder 61 is fixedly connected between the two groups of dust extraction rings 6, and the dust extraction ring 6 is connected to the lower part of the inner cavity of the air extraction cylinder 61. An air extraction groove 62 is formed in the detection cylinder 5, and the air extraction groove 62 is connected to the dust extraction ring 6. A plurality of air extraction holes 63 are equidistantly arranged between the air extraction groove 62 and the insertion groove 52. An air extraction blade 64 is rotatably connected in the air extraction cylinder 61. The top end of the rotating shaft of the air extraction blade 64 is fixedly connected to the bottom end of the output shaft of the first motor 56, and a dust filtering plate 65 is fixedly connected in the air extraction cylinder 61; both sides of the top of the air extraction cylinder 61 are fixedly connected and communicated with exhaust pipes 66, and the other ends of the exhaust pipes 66 are connected to the upper part of the inner cavity of the power connection groove 51. Heat dissipation grooves 67 are equidistantly arranged on the side wall of the detection cylinder 5, and the heat dissipation grooves 67 are connected to the bottom of the inner cavity of the power connection groove 51. Ventilation grooves 68 are equidistantly arranged on the contact plate 53.

[0044] By setting up the above structure, while the first motor 56 drives the detection cylinder 5 to rotate and polish, it also drives the air extraction blade 64 to rotate rapidly in the air extraction cylinder 61. At this time, a suction force is generated below the air extraction blade 64 in the air extraction cylinder 61, and this suction force is transmitted to the inside of the detection cylinder 5 along the dust extraction ring 6, the air extraction groove 62, and the air extraction holes 63, so as to collect the polished debris, prevent the debris from flying everywhere, improve the cleanliness of the detection area. At the same time, the airflow sucked into the air extraction cylinder 61 will enter the upper part of the inner cavity of the power connection groove 51 along the exhaust pipe 66 after being filtered by the dust filtering plate 65, and then enter the lower part of the inner cavity of the power connection groove 51 along the ventilation groove 68 and flow out through the heat dissipation groove 67, so as to dissipate heat from the inside of the power connection groove 51, prevent heat accumulation from occurring in the power connection groove 51 during continuous detection, ensure the detection accuracy, and improve the detection effect; moreover, the airflow entering the lower part of the inner cavity of the power connection groove 51 will also move downward along the gap between the insertion groove 52 and the wiring end, so as to better blow off the debris attached to the surface of the wiring end, prevent the attached debris from affecting the conductive effect of the wiring end, and thus ensure the accuracy of the detection result.

[0045] Refer toFigures 1-4 Among them, the positioning component includes two groups of positioning seats 7, which are respectively fixed on both sides of the top of the mounting plate 31. A turning shaft 71 is fixedly connected between the two groups of positioning seats 7. A second motor 72 is fixedly connected to the side wall of the positioning seat 7, and the output shaft of the second motor 72 is fixedly connected to the end of the turning shaft 71. A turning plate 73 is fixedly connected to the outer wall of the turning shaft 71. A positioning screw rod 74 is rotatably connected between the inner walls on both sides of the turning plate 73. Positioning rods 75 are threadedly connected to both sides of the positioning screw rod 74. A third motor 76 is fixedly connected to the side wall of the turning plate 73, and the output shaft of the third motor 76 is fixedly connected to the end of the positioning screw rod 74; the threading directions of the two positioning screw rods 74 are opposite. A limiting slider 77 is fixedly connected to the side wall of the end of the positioning rod 75, and the bottom end of the limiting slider 77 is in contact with the turning plate 73; positioning plates 8 are fixedly connected to both sides of the belt of the conveyor 1, and the distance between the two positioning plates 8 is equal to the thickness of the ceramic capacitor. The vertical central axis of the detection cylinder 5 is perpendicular to the midpoint of the connection line of the two positioning plates 8.

[0046] Through the setting of the above structure, the ceramic capacitors to be detected are placed on the belt of the conveyor 1 at a certain interval and placed between the two positioning plates 8. As the conveyor 1 operates, the ceramic capacitors are moved to directly below the lifting platform 3, and the operation of the conveyor 1 is stopped. At this time, the second motor 72 is turned on to drive the turning shaft 71 to rotate, so that the two positioning rods 75 are turned to a state parallel to the surface of the lifting platform 3. Subsequently, the third motor 76 drives the positioning screw rod 74 to rotate, so that the two positioning rods 75 move closer to each other along the positioning screw rod 74 at the same time. Finally, the ceramic capacitor is accurately positioned at the center of the two positioning rods 75, which facilitates the subsequent rapid plug-in detection work. While ensuring the stability of the capacitor, the detection efficiency is also effectively improved.

[0047] Refer to Figures 1-8 , Embodiment 2:

[0048] Basically the same as Embodiment 1, on the basis of Embodiment 1, a method for detecting the high-frequency interference resistance performance of a ceramic capacitor is proposed, and the steps are as follows:

[0049] Step 1: Move and position the ceramic capacitor directly below the lifting platform 3 through the conveyor 1;

[0050] Step 2: Clean the terminals of the ceramic capacitor by friction;

[0051] Step 3: Connect the ceramic capacitor to the detector group 4;

[0052] Step 4: Detect the performance of the ceramic capacitor through the detector group 4.

[0053] Refer to Figures 1-8, in the present invention, during use, the ceramic capacitors to be detected are placed on the conveyor belt of the conveyor 1 at a certain interval and placed between the two positioning plates 8. As the conveyor 1 operates, the ceramic capacitors are moved to directly below the lifting platform 3, and the operation of the conveyor 1 is stopped. At this time, the second motor 72 is turned on to drive the turning shaft 71 to rotate, so that the two positioning rods 75 are turned to a state parallel to the surface of the lifting platform 3. Subsequently, the third motor 76 drives the positioning screw 74 to rotate, so that the two positioning rods 75 move closer to each other along the positioning screw 74 at the same time. Finally, the ceramic capacitor is accurately positioned at the center of the two positioning rods 75, ensuring the stability of the capacitor and effectively improving the detection efficiency. At this time, the wiring terminals of the ceramic capacitor also happen to be aligned with the detection cylinder 5; subsequently, the electric push rod 32 drives the lifting platform 3 to move downward, so that the wiring terminals of the ceramic capacitor are inserted into the detection cylinder 5. At the same time, the first motor 56 is turned on, and through the meshing relationship between the linkage gear 57 and the driving gear 561, it drives the detection cylinder 5 to rotate, thereby polishing the wiring terminals of the ceramic capacitor continuously inserted into the detection cylinder 5 with the polishing piece 55 to remove the oxide layer and dirt on the outer wall of the wiring terminal of the ceramic capacitor, ensuring good electrical conductivity and effectively improving the measurement accuracy; finally, the polished wiring terminal will be inserted into the bottom of the contact plate 53. Under the pressure continuously applied downward by the lifting platform 3, the wiring terminal squeezes the bottom arc chamfer of the electrode plate 54, causing the electrode plate 54 to slide towards the side of the compressed second spring 542. When the wiring terminal is completely inserted into the cavity of the contact plate 53, under the rebounding action of the second spring 542, the electrode plate 54 is in close contact with the outer wall of the polished wiring terminal, realizing better electrical conduction. Moreover, under the rebounding action of the first spring 532, the vertical clamping and fixing of the ceramic capacitor are also realized, effectively ensuring the stability of the ceramic capacitor during the detection process.

[0054] In addition, while the first motor 56 drives the detection cylinder 5 to rotate and polish, it also drives the air extraction blade 64 to rotate rapidly in the air extraction cylinder 61. At this time, a suction force is generated below the air extraction blade 64 in the air extraction cylinder 61, and this suction force is transmitted to the inside of the detection cylinder 5 along the dust extraction ring 6, the air extraction groove 62, and the air extraction hole 63, so as to collect the debris falling off during polishing, avoid the debris from splashing everywhere, improve the cleanliness of the detection area. At the same time, the airflow sucked into the air extraction cylinder 61 will enter the upper part of the inner cavity of the power connection groove 51 along the exhaust pipe 66 after being filtered by the dust filter plate 65, and then enter the lower part of the inner cavity of the power connection groove 51 along the ventilation groove 68, and flow out through the heat dissipation groove 67, so as to dissipate heat from the inside of the power connection groove 51, avoid the phenomenon of heat accumulation in the power connection groove 51 during continuous detection, ensure the detection accuracy, and improve the detection effect; moreover, the airflow entering the lower part of the inner cavity of the power connection groove 51 will also move downward along the gap between the insertion groove 52 and the connection terminal, so as to better blow off the debris attached to the surface of the connection terminal, avoid the influence of the attached debris on the conductive effect of the connection terminal, and thus ensure the accuracy of the detection result.

[0055] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered by the protection scope of the present invention.
