[0015] Figure 3 This is a top view of the LED light guide column testing fixture of this utility model. Detailed Implementation

[0016] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] Please see Figure 1-3 This utility model discloses a testing fixture for LED light guide columns, comprising: a base 1, a support column 2 disposed on the base, and a positioning plate 3 disposed on the side of the support column. The positioning plate has a wave-shaped bending structure, which forms several workstation structures for placing the light guide columns to be tested after multiple bending. In this embodiment, sixteen workstation structures are provided, and each workstation structure can test two sets of light guide columns. In addition, thirty-two indicator lights are correspondingly configured to display the test results, with red indicating failure and green indicating success.

[0018] Specifically, the workstation structure includes a cavity 31 opened on the positioning plate. A guide block 32 is provided in the middle of the cavity. The guide block divides the cavity into a first guide groove 33 and a second guide groove 34 for placing the light guide column to be tested. The support column is provided with guide holes (not shown in the figure) that correspond one-to-one with the first guide groove and the second guide groove. An optical fiber sensor (not shown in the figure) is provided on the side of each set of guide holes. The optical fiber sensor is electrically connected to the main controller, wherein the main controller is a microcontroller. An indicator light 4 electrically connected to the main controller is provided on the upper plate of the base.

[0019] Specifically, the inner diameters of the first and second guide grooves are adapted to the outer diameter of the light guide post, and the inner diameter of the guide hole is adapted to the outer diameter of the light guide post. During testing, the light guide post 5 to be tested is slid inward along the outlet end of the first or second guide groove until the tail end of the light guide post is inserted into the guide hole. Limiting blocks 35 are provided on the side of the outlet end of the first and second guide grooves to limit the insertion position of the light guide post. At this time, the fiber optic sensor works to sense whether the light guide post is missing and transmits the signal to the main controller. The main controller displays the missing position and whether it is missing to the corresponding indicator light, which makes it convenient for staff to quickly find the missing position and greatly improves the testing efficiency.

[0020] Specifically, the upper plate of the base is also provided with a start button 6 that is electrically connected to the main controller.

[0021] The beneficial effects of this utility model are: changing the probe detection of the existing technology to fiber optic detection, effectively reducing the later maintenance cost and facilitating the operation of employees, effectively preventing the omission or under-installation of products, improving detection efficiency, and bringing great convenience to production and use.

[0022] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
