Embodiment Construction

[0027] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0028] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

A light-emitting diode (LED) testing device comprises a working table, a support, a push-and-pull assembly and a test fixture. The working table is provided with a positioning station for positioning a to-be-tested substrate with a plurality of LEDs, and the support is fixedly arranged on the working table and located on one side of the positioning station. The push-and-pull assembly comprises a swing arm, a push-and-pull rod and a connecting piece, wherein the swing arm is rotatably connected with the support, the push-and-pull rod is slidably connected with the support, one end of the connecting piece is rotatably connected with one end of the push-and-pull rod far away from the working table, the other end of the connecting piece is rotatably connected with the swing arm, and the rotating axis of the connecting piece and the rotating axis of the swing arm are not coaxial. The test fixture is arranged between the working table and the push-and-pull rod, is fixedly connected with one end of the push-and-pull rod close to the working table and is provided with a plurality of test probes corresponding to anodes and cathodes of the LEDs on the substrate. When the swing arm is rotated, the swing arm drives one end of the connecting piece to rotate, so that the push-and-pull rod can be pushed to slide towards the working table. The testing efficiency of the LED testing device is high.

Description

【Technical field】 [0001] The invention relates to a testing device, in particular to an LED testing device for testing a substrate provided with a plurality of LEDs. 【Background technique】 [0002] At present, the factory needs to light up the LED patch after the substrate. During the test, the two test leads of the multimeter are aligned with the positive and negative poles of the substrate to check whether the LED is on. This method can only test one patch at a time. A good LED substrate, but a substrate with multiple LEDs needs to repeat the test action many times. In this way, the test efficiency is low, making the test cycle longer. 【Content of invention】 [0003] In view of the above situation, it is necessary to provide an LED testing device with high testing efficiency. [0004] A LED testing device, comprising: [0005] The workbench is provided with a positioning station for positioning the substrate with a plurality of LEDs to be tested; [0006] a bracket f...
