Description

Technical Field

[0001] This utility model relates to the field of electrical testing technology, and more specifically, to a potentiometer linearity testing operation platform. Background Technology

[0002] A potentiometer is a type of variable resistor, typically consisting of a resistive element and a rotating or sliding system. A partial voltage output is obtained by moving a movable contact along the resistive element. Before use, potentiometers usually need to be tested to verify that the change in voltage or resistance value is unidirectional and smooth throughout its effective electrical travel.

[0003] Linearity testing is a method used in product development or quality control to evaluate product performance, aiming to check whether the product's response is linearly related to the input conditions. Simply put, when the input variable increases by a certain proportion, the output should also increase by the same proportion or the expected proportion. Linearity testing of a potentiometer verifies whether its output is linearly related to the input (rotation angle or slider position). Specifically, it checks whether the potentiometer's resistance changes uniformly as the knob is turned or the slider moves.

[0004] After production, existing potentiometers require linearity testing. The typical procedure involves an operator manually handling each potentiometer individually, placing it in a test fixture, and then applying power for testing. After testing, qualified and defective potentiometers are separated. Carbon element testing and finished product testing are two distinct quality control steps in potentiometer production, inspecting the potentiometer's components (such as the carbon element) and the final assembled product, respectively. The carbon element is one of the core components in many potentiometers, determining its resistance characteristics. Therefore, individual testing of the carbon element is crucial during potentiometer manufacturing. Finished product testing refers to comprehensive functional and performance testing of the fully assembled potentiometer.

[0005] The existing operating platform test fixtures are complex in structure, inconvenient to operate, and have unreasonable space settings, which is not conducive to long-term testing by testers.

[0006] Therefore, a potentiometer linearity testing platform is needed to solve the above problems. Utility Model Content
