Description

Technical Field

[0001] This utility model relates to the field of LEDs, and more specifically, to an RGB LED testing mechanism. Background Technology

[0002] RGB LEDs require electrical tests during production, including tests for conductivity and color consistency. Traditional testing methods rely on manual operation of probes to contact the pins, which can lead to positioning errors and inaccurate test results.

[0003] Therefore, a new solution is needed to address this problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an RGB LED testing mechanism that achieves rapid clamping and accurate testing of LEDs through the synergistic effect of the pressure pin and the elastic test pin.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: The RGB LED testing mechanism includes a base and a pin holder. The pin holder is embedded in the base and is fixedly connected to the base through a pin holder cover plate. A pin pressing groove is provided on the side of the pin holder cover plate away from the base. A pin pressing is slidably connected in the pin pressing groove. The pin pressing is held in the pin pressing groove by the pin pressing cover plate. The pin holder is provided with a plurality of test pins and a plurality of elastic elements corresponding to the test pins. The test pins can slide relative to the pin holder, and the elastic elements are used to keep the test pins at the bottom. A test contact is provided at the bottom of the test pin, and a wiring hole is provided at the top.

[0006] The present invention is further configured such that: the upper end of the needle holder is provided with six upper needle grooves and the lower end of the needle holder is provided with a corresponding lower needle groove, and the same test needle is provided on the upper needle groove and the corresponding lower needle groove.

[0007] The present invention is further configured such that: the needle holder is a rectangular frame structure, a limiting frame is formed inside the needle holder, a limiting block is provided on the side of the test needle facing the needle holder, and one end of the elastic member abuts against the limiting frame and the other end abuts against the limiting block.

[0008] The present invention is further configured such that: a spring groove is provided on the pressure needle, a spring post is provided on the pressure needle slide groove that can extend into the spring groove, and a return spring is provided between the groove wall of the spring groove and the spring post, and the return spring can keep the pressure needle at the bottom end in a natural state.

[0009] The present invention is further configured such that: the bottom end of the pressure needle is provided with a bayonet, and the two sides of the bayonet are provided with guide slopes.

[0010] In summary, this utility model has the following beneficial effects: In this invention, the height tolerance of each test probe can be automatically compensated by its corresponding elastic element to ensure consistent contact pressure. The pressure pin's locking mechanism fixes the LED edge, and the test probe elastically presses against the pin, forming a dual stability. Attached Figure Description

Detailed Implementation

[0013] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0014] Example: RGB LED testing mechanism, such as Figs. 1-3 As shown, the needle holder 2 is embedded in the center of the base 1 and is locked and fixed by the needle holder cover plate.

[0015] like Fig. 3 As shown, the needle holder 2 is rectangular and has a limiting frame 10 inside. Six corresponding upper needle grooves 8 and lower needle grooves 9 are opened at the upper and lower ends respectively. Six test needles 6 pass vertically through the upper and lower needle grooves 9. Each test needle 6 can slide along the needle groove. The bottom of the test needle 6 is provided with a test contact and the top is provided with a wiring hole for connecting the test circuit. The side of the test needle 6 facing the limiting frame 10 is fixed to the limiting block 11. The two ends of the elastic member 7 press against the limiting frame 10 and the limiting block 11 respectively, so that the test needle 6 maintains the bottom position in the natural state. The pressure needle cover plate 17 covers the needle holder cover plate, and the surface of the pressure needle 5 has a sliding groove 4.

[0016] like Figs. 1-3 As shown, the pressure needle 5 is embedded in the slide groove, with a retaining groove 15 extending from the bottom. Guide slopes 16 are designed on both sides of the retaining groove 15. A spring groove 12 is opened on the side of the pressure needle 5. A spring post 13 fixed in the slide groove is inserted into the spring groove 12, and a return spring 14 is set between the two. The return spring 14 keeps the pressure needle 5 at its lowest position in its natural state.

[0017] During testing, the RGB LED component is fixed on the test platform with the pins facing upwards. The test mechanism is located above the test platform, with the pressure pin 5 at the bottom and the reset spring 14 in a naturally extended state. The test pin 6 is kept at the lowest position due to the action of the elastic element 7.

[0018] Next, the entire testing mechanism moves downwards, and the guide slope 16 at the bottom of the pressure pin 5 first contacts the edge of the LED. Guided by the slope, the LED automatically slides into the bayonet 15 of the pressure pin 5, completing horizontal positioning. The mechanism continues to press down, and the pressure pin 5 slides upwards relative to the LED along the groove 4 of the pressure pin 5, compressing the return spring 14; at the same time, the bayonet 15 locks the edge of the LED to prevent displacement during the test.

[0019] At this time, the LED pin pushes the test pin 6 upward, and the test pin 6 slides upward in the pin groove, compressing the elastic element 7 inside. The reverse elastic force of the elastic element 7 drives the test contact at the bottom of the test pin 6 to press tightly against the LED pin, forming a stable electrical connection.

[0020] External testing equipment inputs a detection signal to the pin through the wiring hole at the top of test pin 6 to collect parameters such as the conductivity and chromaticity value of the RGB LED.

[0021] The elastic element 7 of the test pin 6 provides adaptive pressure, compensates for pin height tolerances, ensures consistent contact force at all contacts, and avoids damage from poor connection or overvoltage.

[0022] After the test is completed, the entire mechanism is raised upwards. The return spring 14 releases energy, pushing the pressure pin 5 down the slide to the bottom, and the bayonet 15 disengages from the LED edge. The elastic element 7 inside the test pin 6 extends synchronously, pushing the test pin 6 down to reset to the initial position, and the test contact is completely separated from the LED pin.

[0023] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
