Description

Technical Field

[0001] This utility model relates to the field of inductance testing fixture technology, specifically an inductance testing jig. Background Technology

[0002] After production, inductors need to be tested. During testing, the inductor is connected to the circuit by contacting the test pins with the inductor pins to test whether it is working properly. Traditionally, testing is done manually. There is now an automated testing device that can perform automatic testing. However, the existing automated inductor testing device has a complex structure, high overall manufacturing cost, and increased operation and maintenance costs.

[0003] Chinese patent document CN219496554U discloses a finished product testing fixture, including a support, a vertical plate, a reciprocating motion device, a moving frame, a pneumatic nozzle, a detection component, a conveyor belt, a cylinder, and a push plate. The vertical plate is fixed to the top of the support, the reciprocating motion device is disposed on the vertical plate, and the moving frame is fixed to the output end of the reciprocating motion device. The reciprocating motion device is used to drive the moving frame to move back and forth. The pneumatic nozzles are respectively fixed to two ends of the moving frame. The detection component is fixed to the outer wall of the support, with one of the pneumatic nozzles facing the detection component. The conveyor belt is installed on the outer wall of the support. This application greatly simplifies the structure of the entire testing device while ensuring the completion of inductor testing, reducing the cost of manufacturing, use, and maintenance of the testing device. However, this device cannot mark qualified and unqualified products, which can easily lead to confusion between qualified and defective products. Utility Model Content

[0004] The purpose of this invention is to provide an inductance testing fixture to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An inductance testing fixture includes a base, a platform at the top of the base, an upright back plate mounted on the rear side of the platform, a support plate on the front side of the back plate, a pair of guide rods erected between the support plate and the platform, a slide plate slidably mounted on the guide rods, a test cylinder mounted on the top of the support plate, a push rod of the test cylinder connected to the top of the slide plate, and an upper testing fixture at the bottom of the slide plate.

[0007] The platform is equipped with a lower inspection fixture, which faces the upper inspection fixture and is mounted on a carrier plate.

[0008] A marking component is provided on one side of the lower detection fixture;

[0009] The marking assembly includes a base frame, the top of which is an inclined surface that slopes toward the lower detection fixture. A guide rail extending toward the lower detection fixture is mounted on the inclined surface. A mounting frame is slidably disposed on the guide rail. A marker pen is mounted on the mounting frame with its tip pointing toward the lower detection fixture. A marking cylinder is mounted on the inclined surface and its push rod is connected to the rear end of the mounting frame.

[0010] Beneficial effects:

[0011] This fixture is specifically designed for testing the performance of inductive components. Qualified products are automatically marked by a marking component, making it easy to distinguish between qualified and defective products. Attached Figure Description
