[0024] Please see Figures 1 to 3 The image shows an LED bead testing fixture of the present invention, including a fixture body 10, which is a cylindrical structure. On the axial direction of the fixture body 10, a placement groove 101 is provided in the middle of the end face of one end of the fixture body 10. The placement groove 101 is used to place LED beads. Clamping components 30 are symmetrically provided on two opposite sides of the placement groove 101. The clamping components 30 are used to clamp and fix the LED beads in the placement groove 101.

[0025] Specifically, the bottom wall of the placement groove 101 is provided with a plurality of placement holes 102, and a pad contact point pin 20 is placed in the placement hole 102. The pad contact point pin 20 is used to contact the bottom of the pad of the lamp bead. In this embodiment, the bottom wall of the placement groove 101 is provided with four placement holes 102, which are respectively located in the four corner areas of the placement groove 101. Each placement hole 102 is provided with an adjustable position pad contact point pin 20, so that the pad contact point pin 20 can be adaptively adjusted according to the position of the connection point at the bottom of the lamp bead pad during actual testing.

[0026] Furthermore, two mounting grooves 103 are symmetrically provided on two opposite sides of the placement groove 101. The mounting grooves 103 are arranged radially along the clamp body 10 and communicate with the placement groove 101. The mounting grooves 103 are adapted to the clamping block 31. In this embodiment, the bottom wall of the mounting groove 103 is higher than the bottom wall of the placement groove 101, and the total length of the mounting groove 103 is greater than or equal to the total length of the clamping block 31.

[0027] Furthermore, a guide groove 104 is provided on one side of the placement groove 101. The guide groove 104 is arranged radially along the fixture body 10 and communicates with the placement groove 101. The bottom wall of the guide groove 104 is flush with the bottom wall of the placement groove 101, and one end of the guide groove 104 away from the center of the placement groove 101 is spatially connected to the outer edge of the fixture body 10, so that the lamp bead can be pushed into the placement groove 101 along the guide groove 104 for fixing, which greatly improves the accuracy of the placement position of the lamp bead on the fixture body 10.

[0028] Furthermore, the fixture body 10 is also provided with a control switch 40, which is located on the side where the guide groove 104 is located.

[0029] Furthermore, a scale 50 is provided on the end face of the fixture body 10, and the scale 50 is located on the side of the placement groove 101 opposite to the guide groove 104.

[0030] Furthermore, multiple positive and negative switches 60 are provided on the end face of the other end of the fixture body 10. Each positive and negative switch 60 corresponds one-to-one with a solder pad contact point pin 20, and the positive and negative switches 60 are electrically connected to the solder pad contact point pin 20 via wires. In practical applications, the arrangement of multiple positive and negative switches 60 can accommodate different series and parallel configurations, thus enabling compatibility with LED products having different solder pad pin supports, greatly improving applicability. As a specific example, in this embodiment, four positive and negative switches 60 are provided on the end face of the other end of the fixture body 10. The arrangement of these four positive and negative switches 60 achieves the purpose of energizing and lighting the test LED for testing.

[0031] As an example, the clamping assembly 30 includes a clamping block 31 and a limiting pin 32 for fixing the clamping block 31. The lamp bead is clamped and fixed in the placement groove 101 by changing the distance between the two clamping blocks 31. The shape of one end of the clamping block 31 near the center of the placement groove 101 is adapted to the shape of the outer edge of the lamp bead to achieve a tight fit between the clamping block 31 and the outer edge of the lamp bead. In this way, clamping blocks with different clamping ends and different thicknesses can be designed. When testing lamp beads of different shapes and specifications, only the clamping block in the mounting groove 103 needs to be replaced, which greatly improves the replacement efficiency. Moreover, the clamping block can be used in both directions, making the operation very convenient.

[0032] Furthermore, the clamping block 31 is provided with a limiting hole 301, which is an oblong hole structure, and the long axis of the limiting hole 301 is set along the length of the clamping block 31. A limiting pin 32 is provided in the limiting hole 301, and the limiting pin 32 is threadedly connected to the bottom wall of the mounting groove 103 to fix the position of the clamping block 31.

[0033] In practical use, the LED bead testing fixture of this utility model can be used as follows: First, loosen the limiting pin 32 and retract the end of the clamping block 31 near the center of the placement groove 101 into the mounting groove 103. Then, slowly push the LED bead into the placement groove 101 along the guide groove 104. During the placement of the LED bead, the four pad contact point pins 20 in the placement groove 101 can be adjusted to make adaptive contact with the bottom of the pads on the LED bead. When the LED bead is in the placement groove 101, the two clamping blocks 31 on opposite sides of the placement groove 101 can be moved so that the clamping ends of the two clamping blocks 31 can tightly abut against the outer edge of the LED bead. Then, tighten the limiting pin 32 accordingly to fix the position of the clamping blocks 31, thereby achieving the purpose of firmly fixing the LED bead in the placement groove 101. Finally, the LED bead is powered on and lit by turning on the control switch 40 and the corresponding positive and negative switches 60 to achieve the performance test of the LED bead.

[0034] In summary, the beneficial effects of this LED bead testing fixture are as follows: high applicability, compatible with LED beads of different specifications and LED beads with multiple pad pin brackets, enabling multiple LED bead products to share a single testing fixture, greatly reducing production costs. Furthermore, standardized accessories facilitate management and storage, thereby effectively ensuring production efficiency and product quality stability. Specifically, by setting clamping components on two opposite sides of the placement slot on the fixture body, the clamping components include clamping blocks and limiting pins for fixing the clamping blocks. By changing the distance between the two clamping blocks, the LED bead is clamped and fixed within the placement slot, making operation very convenient and greatly improving testing efficiency.
