Description

Technical Field

[0001] The utility model belongs to the technical field of capacitor detection, and particularly relates to a test device for the capacitance value and insulation resistance of a ceramic capacitor. Background Technique

[0002] The main purposes of testing the capacitance and resistance of a ceramic capacitor are to ensure that its electrical performance meets the design requirements and to ensure stable and reliable operation during use. The following is a specific purpose analysis. The main purpose of capacitance testing is to measure the capacitance value of the ceramic capacitor to verify whether it meets the product specifications and design requirements. The capacitance value is one of the basic parameters of a capacitor and has an important impact on the stability and performance of the circuit. The insulation resistance is also one of the important indicators for evaluating its electrical performance. The purpose of insulation resistance testing is to measure the insulation resistance value between the two terminals of the capacitor to evaluate the insulation performance of the capacitor. A high insulation resistance value indicates that the capacitor has good insulation performance, which helps to prevent problems such as current leakage and short circuits. Through capacitance and resistance testing, it can be ensured that the electrical performance of the ceramic capacitor meets the design requirements, thereby guaranteeing the quality and reliability of the entire electronic product.

[0003] When the existing ceramic capacitors are tested, the capacitors cannot be quickly fixed to ensure that the positive and negative electrodes of the detection mechanism can be stably connected to the two pins of the capacitor respectively; in addition, after the detection is completed, the capacitors need to be manually collected and taken out, and the operation is relatively cumbersome, which affects the detection efficiency. Content of the Utility Model

[0017] As a further improvement of the above technical solution: an activity groove is formed on the support plate, the activity groove has a stepped structure, and the suction cup is installed in the activity groove.

[0018] The beneficial effects of this improvement are as follows: the activity groove provides an effective deformation space for the suction cup, enabling the center of the suction cup to sink and adsorb the surface of the capacitor.

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description of this part is only exemplary and explanatory, and should not have any restrictive effect on the protection scope of the present invention.

[0030] Embodiment 1:

[0031] As Figure 1As shown in FIGS. 5, a test device for the capacitance value and insulation resistance of a ceramic capacitor includes a chassis 1. A vertical frame 2 is installed on one side of the chassis 1. A collecting plate 3 is installed in the chassis 1. An electric push rod 4 and a controller 5 are installed at the top of the vertical frame 2. The bottom end of the piston rod of the electric push rod 4 is installed with a power supply component 6. A support plate 7 is installed on the chassis 1 below the power supply component 6. The bottom of the support plate 7 is respectively rotatably connected to a first connecting seat 71 and an electric telescopic rod 72 through a pin shaft. The first connecting seat 71 is installed on the chassis 1. The other end of the electric telescopic rod 72 is rotatably connected to the chassis 1 through a pin shaft. A fixing component 9 and an elastic support 10 are installed on the support plate 7. The fixing component 9 includes a suction cup 91. A connecting plate 92 is installed on the suction cup 91. The connecting plate 92 is installed at the top end of the piston rod of an electromagnet 93. The electromagnet 93 is installed on the support plate 7. The fixing component 9 can quickly adsorb and fix the capacitor 8. Cooperating with the use of the elastic support 10 enables the power supply component 6 to be stably electrically connected to the capacitor 8 for stable testing. When the electric telescopic rod 72 extends, the support plate 7 tilts to quickly remove the capacitor 8. The power supply component 6 includes an insulating rod 61. A first pin end 62 and a second pin end 63 are connected to the side of the insulating rod 61. The first pin end 62 and the second pin end 63 are electrically connected to a power supply line 64. The first pin end 62 and the second pin end 63 can be crimped on the pins of the capacitor 8 to stably output current to the capacitor 8. The elastic support 10 includes a bottom plate 101 and a support member 102. The number of the support members 102 is two and they are arranged opposite to each other left and right. The support member 102 is an elastic M-shaped plate structure. The support member 102 can effectively position the positions of the two pins of the capacitor 8, so that the pins of the capacitor 8 are accurately connected to the first pin end 62 and the second pin end 63. One end of the support member 102 is connected to the bottom plate 101. The bottom plate 101 is a polytetrafluoroethylene plate structure. When the support member 102 is subjected to the pressure of the first pin end 62 and the second pin end 63, it can generate elastic deformation, so that the contacts of the capacitor 8 are stably connected to the first pin end 62 and the second pin end 63. An activity groove 73 is formed on the support plate 7. The activity groove 73 is in a stepped structure and the suction cup 91 is installed in the activity groove 73. The activity groove 73 provides an effective deformation space for the suction cup 91, so that the center of the suction cup 91 sinks to adsorb the surface of the capacitor 8. When the electric telescopic rod 72 contracts to the end of its stroke, the top surface of the support plate 7 is parallel to the bottom surface of the chassis 1. The electric telescopic rod 72 and the collecting plate 3 are arranged opposite to each other on both sides of the first connecting seat 71. When the electric telescopic rod 72 extends, it drives the support plate 7 to flip, effectively unloading the capacitor 8 onto the collecting plate 3.

[0032] The working principle of this technical solution is as follows: In the initial state, the electric push rod 4 and the electric telescopic rod 72 contract to the minimum stroke. The capacitor 8 is placed on the suction cup 91, and the two pins of the capacitor 8 are placed on the two support members 102. The controller 5 is used to control the solenoid magnet 93 and the electric push rod 4 to operate in sequence. The contraction of the solenoid magnet 93 drives the connecting plate 92 to move downward, thereby causing the center of the suction cup 91 to sink downward, so that the capacitor 8 is stably adsorbed and fixed by the suction cup 91. The electric push rod 4 extends to drive the power supply assembly 6 to move downward, so that the first pin end 62 and the second pin end 63 installed on the insulating rod 61 are respectively pressed on the two pins of the capacitor 8, and the support member 102 undergoes elastic deformation. After the test, the solenoid magnet 93 and the electric push rod 4 are reset. Subsequently, the electric telescopic rod 72 extends to drive the support plate 7 to rotate with the pin on the first connecting seat 71 as the fulcrum, so that the capacitor 8 slides along the inclined surface of the support plate 7 and falls into the collection plate 3 for collection.
