DETAILED DESCRIPTION
[0019] The technical solutions in the embodiments of the present invention are described clearly and completely below.

[0021] For the three-color LED testing device designed in this scheme, it is mainly used in conjunction with the support plate frame 6 set up and the test loading assembly. When the circuit board with the LED lamp body needs to be tested with one side facing down, it can also be well adapted to the test. That is, it is mainly through the practical cooperation of the knob body 704 and the regulating screw column 702 set up to adjust the position of the regulating carrier board 701, so that the three-color LED circuit board has a flexible support and positioning, avoiding the three-color LED lamp body on the circuit board from affecting the detection work.
[0022] When the three-color LED is subjected to assembly line testing, that is, the circuit boards pass through the bottom side of the support frame 2 one by one, and are tested one by one through the test assembly 5 at the bottom of the transmission connecting shaft 4, there is no need to install and use auxiliary components, that is, the circuit board is supported by the adjustment carrier 701, that is, the adjustment screw 702 is driven to rotate by rotating the knob body 704, and then the position of the adjustment carrier 701 is raised and lowered until a suitable support is provided for the circuit board. When the circuit boards pass through the bottom position of the test assembly 5 one by one, the test assembly 5 tests them and leaves the inspection station after the test is completed. During this process, the auxiliary ball 904 arranged on the carrier block body 903 provides a protection for the circuit board to avoid friction.
[0023] When it is necessary to test the three-color LED on a single circuit board, in order to facilitate its detection work, this process requires installing an auxiliary component at the tail end of the regulating carrier 701, and the installed auxiliary component is used in conjunction with the loading positioning structure, wherein the regulating carrier 701 in the test loading assembly is arranged at the inner side of the support plate frame 6, and a regulating screw column 702 is provided with a threaded connection through the regulating carrier 701, one end of the regulating screw column 702 is arranged through the auxiliary bearing 703, and the end of the regulating screw column 702 is fixedly provided with a knob body 704, and the auxiliary bearing 703 is embedded and fixedly arranged in the support plate frame 6, the knob body 704 is set as a round block, and the outer side wall of the round block is provided with anti-slip grooves; here, the regulating carrier 701 and the support plate frame 6 are set in the same number of groups, that is, a regulating carrier 701 is provided on the inner side of a support plate frame 6, and one side of the regulating carrier 701 is in contact with the inner side of the support plate frame 6; the tail end of the regulating carrier 701 is connected with an auxiliary component.
[0024] As for the setting of the auxiliary component, the loading thread groove 801 in the auxiliary component is set at the tail end of the regulating carrier 701, the mounting plate 802 is provided with a mounting hole 805, and the mounting plate 802 is fixed by a positioning screw 806, and one end of the positioning screw 806 is fixedly provided with an auxiliary handle 807, and the auxiliary handle 807 is set as a cylinder, and the side wall of one end of the cylinder is equidistantly provided with anti-slip convex strips; an auxiliary spring 803 is symmetrically fixed on one side of the mounting plate 802, and the other end of the auxiliary spring 803 is fixedly provided on one side of the limit block 804, that is, when the auxiliary component is installed and used, first First, place the mounting plate 802 tightly against the rear end of the regulating carrier 701, and align the mounting hole 805 on the mounting plate 802 with the loading thread groove 801 at the rear end of the regulating carrier 701. Then, threadedly connect them through the positioning screw 806 until the auxiliary handle 807 is tightened. At this time, the limit block 804 set at one end of the auxiliary spring 803 is on the regulating carrier 701, and the bottom end of the limit block 804 is in contact with the regulating carrier 701. The installation of the auxiliary component is completed. It is easy to assemble and disassemble, and can be disassembled and assembled according to actual test work requirements, with better test work flexibility.
[0025] When placing the circuit board, if the board with the three-color LED needs to face down, the position of the regulating carrier 701 needs to be regulated, that is, the regulating screw 702 is rotated by the knob body 704 until the regulating carrier 701 is adjusted to a suitable position. Here, the outer wall of the knob body 704 is provided with anti-slip grooves to facilitate the operation of the staff. After reaching the appropriate position, the circuit board is placed and the two sides of the circuit board are slid on the regulating carrier 701. During the sliding placement process, the auxiliary balls 904 provided on the carrier block body 903 provide a sliding auxiliary effect for the circuit board and try to avoid friction damage to the board body to ensure The quality of the circuit board body; during the sliding process, until the other end of the circuit board contacts the limit stop 804, and continues to push the circuit board until the circuit board is in the detection position, that is, directly below the test component 5. At the same time, the auxiliary spring 803 connected to the limit stop 804 is in a compressed state. When the circuit board is moved to the detection position, in order to position the circuit board, the staff will rotate the positioning strip 907 on the side of the carrier block body 903 near the front end of the circuit board, that is, rotate it to the upper position, so that the positioning strip 907 blocks and limits the front end of the circuit board, that is, adjusts the carrier board A loading positioning structure is equidistantly provided on one side of 701, and the loading positioning structure includes a positioning groove 901, a through groove body 902, a bearing block body 903, an auxiliary ball 904, a limiting ridge 905, a U-shaped connector 906, a positioning strip 907, an auxiliary latch 908, a positioning auxiliary inclined surface 909, an elastic ridge 1001 and a limiting groove 1002; the positioning groove 901 is equidistantly provided on one side of the regulating carrier 701, and a through groove body 902 is provided on one side of the positioning groove 901, and the through groove body 902 extends to the side position of the regulating carrier 701, and the bearing block body 903 is connected to the positioning groove 901. 1 is adapted for card connection, and the number of groups of the supporting card block body 903 and the accommodating positioning groove 901 are the same. A limiting ridge 905 is fixedly provided on one side of the supporting card block body 903, and a U-shaped connector 906 is fixedly provided on the side wall of the limiting ridge 905. A positioning card strip 907 is provided on the port of the U-shaped connector 906 for rotational connection. An auxiliary pin 908 is inserted through the U-shaped connector 906 and the positioning card strip 907; an auxiliary ball 904 is movably embedded in the supporting card block body 903, and one supporting card block body 903 is provided with an auxiliary ball 904. The limiting ridge 905 is adapted for card connection with the through-groove body 902.
[0026] The cam 906 is fixed with an elastic ridge 1001, which is adapted to engage with the limiting groove 1002. The limiting groove 1002 is arranged at the side of the positioning strip 907. After the positioning strip 907 is rotated, the positioning strip 907 is pressed again so that the limiting groove 1002 on the positioning strip 907 is engaged with the positioning strip 907 on the U-shaped connector 906, providing a position stabilization effect for the positioning strip 907. At this time, the knob body 704 is continued to drive the regulating screw column 702 to rotate, and the regulating carrier 701 is adjusted to rise until the side position of the circuit board contacts the top of the support plate frame 6, thereby positioning the circuit board for loading and positioning. The test assembly 5 can then be used for testing.
[0027] After the test work is completed, the tested three-color LED circuit board needs to be disassembled and another three-color LED circuit board needs to be reinstalled. During this process, first use your fingers to rotate and reset the positioning card strip 907, that is, release the blocking limit of the positioning card strip 907 on the front end of the circuit board, and then rotate the knob body 704 in the opposite direction. Under the driving action of the regulating screw column 702, the position of the regulating carrier plate 701 is moved downward. For the positioning contact of the circuit board, at the same time as the positioning contact, the circuit board is ejected outward a certain distance under the rebound action of the auxiliary spring 803, which makes it easier for the staff to take out the circuit board, and then reload another three-color LED circuit board to be tested, and follow the corresponding operations.
[0028] In this solution, on the one hand, an auxiliary component is set at the tail end of the control carrier 701, and the auxiliary component is detachable, which is convenient for assembly and disassembly and can adapt well to different forms of testing work requirements to improve the flexibility of testing work; on the other hand, the carrier card block body 903 in the loading and positioning structure is clamped with the accommodating positioning groove 901. If the carrier card block body 903 needs to be disassembled, the carrier card block body 903 can be directly taken out from the accommodating positioning groove 901.
[0029] During actual testing, for setting multiple groups of three-color LEDs on the same circuit board, in order to improve the testing efficiency, it is generally necessary for the staff to hold the circuit board for testing, that is, to place the three-color LED circuit board on the adjustment carrier 701. At this time, the auxiliary components and the loading positioning structure need to be disassembled, that is, it is only necessary to adjust the adjustment carrier 701 to the appropriate position through the knob body 704. After the test of the three-color LED at a certain place on the circuit board is completed, the staff slides the position of the adjustment circuit board by hand to move the three-color LED at another place to the inspection station, and then performs the test work through the test component 5; the auxiliary components can also be installed to cooperate with the staff to operate, that is, the limit block 804 in the auxiliary component provides a simple limiting effect on the circuit board.
