[0021] In order to make the technical means, creative features, objectives and effects of the utility model easy to understand, the utility model is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0022] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings.

[0023] Example 1

[0024] like Figure 1-4As shown, an LED light strip detection device includes a conveyor belt 1. Telescopic rods 3 are provided on both sides of the top of the conveyor belt 1, and push plates 2 are provided at the ends of the telescopic rods 3. A shell 4 is provided in the middle of the top of the conveyor belt 1, and an industrial camera 8 is provided at the top of the inner side of the shell 4. A positioner 7 and a power-on structure connected to the conveyor belt 1 are provided on both sides of the industrial camera 8, and a coder 11 is provided on the side of the power-on structure.

[0025] The bottom end of the push plate 2 is matched with the middle of the top end of the conveyor belt 1, so that when the telescopic rod 3 drives the push plate 2 to move, a large friction force between the push plate 2 and the telescopic rod 3 can be avoided.

[0026] A control panel 5 is provided at the top of the shell 4, and the control panel 5 is respectively connected to the shell 4, the industrial camera 8, the inkjet printer 11 and the power-on structure wires. The working parameters of the shell 4, the industrial camera 8, the inkjet printer 11 and the power-on structure can be set through the control panel 5, and the brightness of the lamp beads can be photographed by the industrial camera 8.

[0027] The power supply structure includes a lifting rod 9 arranged inside the housing 4, and a power supply 10 installed at the bottom end of the lifting rod 9 and connected to the light bar.

[0028] A T-shaped slide groove is provided at the bottom end of the lifting rod 9, and the top end of the power supply 10 is located inside the slide groove of the lifting rod 9. The top size of the power supply 10 is adapted to the inside of the slide groove of the lifting rod 9. The power supply 10 can be quickly disassembled through the slide groove, and the telescopic rod 3 drives the push plate 2 to adjust the position, so that LED light strips of different widths can be detected on the conveyor belt 1.

[0029] The inkjet printer 11 is installed on the side of the power supply 10 to change the distance between the inkjet printer 11 and the LED light bar to avoid the lower installation colliding with the LED light bar and the higher installation causing unclear coding.

[0030] There are openings on both sides of the bottom of the shell 4, and the opening height is adapted to the height of the push plate 2 and the light strip, and the opening width is adapted to the middle of the top of the conveyor belt 1. When the push plate 2 clamps LED light strips of different widths, the darkness inside the shell 4 is brought to the lowest state to improve the detection results of the LED light strips.

[0031] A protective pad 6 is provided on the side of the push plate 2. The protective pad 6 is made of soft insulating material and can protect the LED light strip when the push plate 2 clamps it. The protective pad 6 has a depression under the squeezing of the push plate 2 and the LED light strip, thereby improving the stability of the LED light strip and preventing the lifting rod 9 from driving the power supply 10 to descend and failing to power on the LED light strip for light detection.

[0032] Working principle:

[0033] When in use, the LED light strip is placed in the middle of the top end of the conveyor belt 1, and is transported to the inner side of the shell 4 through the conveyor belt 1. At the same time, the positioner 7 detects the position of the LED light strip to stop the conveyor belt 1, and drives the push plate 2 to move toward the LED light strip through the telescopic rod 3, so that the two push plates 2 clamp and fix the LED light strip. At the same time, the lifting rod 9 drives the power supply 10 to descend, so that the power supply 10 contacts the LED light strip, and the powered lamp beads of the LED light strip are illuminated. Then the industrial camera 8 is used to detect and take pictures of the light source, and the inkjet printer 11 inkjet codes the LED light strip to determine whether the LED light strip is a qualified product, and moves out through the other end of the shell 4, so that the LED light strip is continuously tested, so that the detection efficiency of the LED light strip is higher.

[0034] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
