Through the limitation of the supporting balls 24, the reliability and smoothness of the movement of the second detection plate 18 in the Y direction can be improved.

[0037] Further, such as Figure 5As shown, the locking plate 25 is preferably C-shaped, and the locking plate 25 and the blocking block 26 are anti-slip in the Y direction and slidingly connected in the Z direction. Through the limitation of the locking plate 25 and the blocking block 26, the No. 2 detection plate 18 can be pushed to move in the Y direction through the No. 1 telescopic cylinder 8, and can also adapt to the lifting and lowering of the No. 2 detection plate 18.

After the diffuse reflection effect of the inner wall of the No. 1 spherical shell 35, the light signal is received by the No. 1 receiver 31 and transmitted to the computer. The light string is then tested by the No. 2 detection component 16. That is, when the LED light of the light string is aligned with the No. 2 light inlet 40, the light enters the No. 2 spherical shell 36 through the transmission glass 41 and is finally received by the No. 2 receiver 38, and the light signal is transmitted to the computer. In addition, during the testing process, the No. 1 light blocking column 30 and / or the No. 2 light blocking column 43 can be removed as needed to observe the situation.

[0046] The above embodiment of the present invention provides an LED light string detector. According to the distance between the LED lights on the light string, the distance between the first detection component 17 and the second detection component 16 is matched and adjusted, that is, two adjacent LED lights can correspond to the first light inlet 27 and the second light inlet 40 respectively; the second telescopic cylinder 10 controls the movement of the end plate 13, and the elastic ribs 14, the fixing plate 15 and the second detection plate 18 cooperate to clamp and fix the light string. Then, the light string can be controlled by the light string carrying drive mechanism to adjust the movement in the X, Y, and Z directions, so that the light string can be continuously tested and matched with the first light inlet 27 and the second light inlet 40. After the test is completed, the light string is removed, and the second detection plate 18 is reset to perform the next round of testing, which facilitates efficient testing.

[0047] In addition, the No. 1 transmission motor 6 and the No. 2 transmission motor 19 are preferably servo motors for easy transmission and resetting; the No. 1 telescopic cylinder 8, the No. 2 telescopic cylinder 10, and the No. 3 telescopic cylinder 22 are preferably hydraulic telescopic cylinders or electric telescopic cylinders for easy fixed-length control; the models and circuit connections of each component are not specifically limited and can be flexibly set in actual application.

[0048] The circuits, electronic components and modules involved are all existing technologies and can be fully implemented by those skilled in the art. Needless to say, the content protected by the present invention does not involve improvements to software and methods.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
