Description

Technical Field

[0001] This utility model belongs to the field of capacitor testing technology, specifically a capacitor testing device. Background Technology

[0002] Capacitance testing equipment is crucial in electronics manufacturing, repair, and R&D. It measures key performance parameters of capacitors, such as capacitance, ESR, and leakage current, ensuring their stability and quality. With advancements in electronic technology, capacitance testing equipment has continuously evolved, boasting higher precision, higher frequency measurement capabilities, and intelligent features. Modern equipment, such as digital capacitance meters, LCR meters, ESR meters, and automated testing systems, are widely used in power systems, signal processing, and high-frequency circuits to ensure the normal operation and performance optimization of electronic products. Regular testing with these devices can effectively extend the lifespan of capacitors, prevent malfunctions, and thus improve the reliability and efficiency of the overall electronic system.

[0003] A search revealed an existing patent (publication number: CN215142305U) that discloses a fully automatic high-precision testing device for electrolytic capacitors. The device includes a fixed block, an air supply chamber, and a testing body. The air supply chamber is fixedly connected to the right side of the fixed block, and a cylinder is fixedly connected to the right side of the air supply chamber. A piston rod is movably connected inside the cylinder, and a linkage lever is movably connected to the top of the piston rod. A limit rod is movably connected to the middle of the linkage lever, and a connecting rod is movably connected to the rear of the linkage lever. A fan is fixedly connected to the top of an infrared thermometer. The fan can drive rapid airflow to accelerate heat dissipation from the surface of the testing device, preventing overheating and significant errors in the test results, thus improving the device's practicality. The diameter of the limit hole is similar to the diameter of the capacitor, allowing for better fixation of the capacitor, further enhancing the device's practicality. A pressure sensor monitors the compressive force, preventing excessive pressure from damaging the capacitor under test, thus improving the device's practicality.

[0004] However, in actual use of the above solutions, the fixed setting of capacitors in the testing equipment may limit the flexibility and applicability of the equipment, making it unable to adapt to the testing of different types or specifications of capacitors. Secondly, long-term use of fixed settings may lead to a decrease in testing accuracy, especially when facing aging or deformed capacitors, where fixed settings may not provide accurate measurement results. In addition, fixed-configuration equipment may not be easy to upgrade and cannot meet the testing needs of technological advancements or new types of capacitors.

[0005] Therefore, this utility model provides a capacitance testing device. Utility Model Content

[0006] To overcome the shortcomings of existing technologies and solve the problem that capacitors cannot be rotated in testing equipment, this utility model proposes a capacitance testing device.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The capacitance testing device of this utility model includes a base, a support frame is fixedly connected to the rear top of the base, a testing host is fixedly connected to the front top of the support frame, a transmission ring is rotatably connected to the inner side of the top of the base, a transmission component is provided at the front end of the transmission ring, and a limit component is provided on the inner side of the transmission ring.

[0008] Furthermore, the transmission assembly includes a motor, which is fixedly connected to the inner side of the base, and a worm gear is fixedly connected to the right side of the motor, with the worm gear rotatably connected to the base.

[0009] Furthermore, a worm gear ring is fixedly connected to the outer end of the inner side of the transmission ring, and the worm gear ring is meshed with the worm.

[0010] Furthermore, the limiting component includes a connecting rod, the connecting rod is fixedly connected to the inner side of the transmission ring, the limiting frame is fixedly connected to the inner side of the connecting rod, the middle inner side of the limiting frame is slidably connected to left and right opposing first clamping blocks, and the inner side of the first clamping blocks is fixedly connected to an electric push rod.

[0011] Furthermore, a first transmission rod is rotatably connected to one end of the inner side of the first clamping block, a transmission disk is rotatably connected to the inner side of the first transmission rod, a limit post is rotatably connected to the inner side of the transmission disk, and the limit post is fixedly connected to the limit frame.

[0012] Furthermore, a second transmission rod is rotatably connected to the outer side of the transmission disk, and a second clamping block is rotatably connected to one end of the outer side of the second transmission rod. The second clamping block is slidably connected to the limiting frame.

[0013] Furthermore, a support ring is fixedly connected to the outer side of the top of the base, and a placement platform is rotatably connected to the top of the support ring. The outer wall of the placement platform is provided with evenly distributed sliding grooves, which are slidably connected to the first clamping block and the second clamping block.

[0014] Furthermore, a rubber layer is provided on the outer side of the top of the placement platform.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The capacitance testing device of this utility model uses a motor to drive a worm gear ring and a transmission ring to rotate. The transmission ring then drives the top limiting component and other structures and capacitors to rotate, thereby adapting to different types of capacitors, ensuring optimal contact and improving measurement accuracy. Simultaneously, it increases the flexibility of the device to meet different testing needs. Angle adjustment also optimizes the device layout and avoids poor contact caused by space constraints.

[0017] 2. The capacitance testing device of this utility model uses an electric push rod to drive a first clamping block to move in opposite directions. This movement of the first clamping block, along with the rotation of a limiting post via a first transmission rod, simultaneously drives a second clamping block to move in opposite directions via a second transmission rod. This movement is synchronized with the first clamping block, thus fixing the capacitor. This significantly improves the accuracy and efficiency of testing. Fixing the capacitor ensures stable contact, reduces errors caused by poor contact and vibration, and enhances measurement reliability. Furthermore, it prevents capacitor displacement, reduces human error, and improves batch testing efficiency.
