[0025] As Figure 1 shown, a lighting test device is used to perform a lighting test on the lamp beads on product 1. Product 1 includes a radiator and lamp beads fixed on the radiator through a PCB board. The lighting test device includes a dark box 11 and a conveying module for conveying product 1 into the dark box 11. A visual detection module, a monitoring camera module, and a probe test module are arranged in the dark box 11. The probe test module includes a probe 2 and a driving member for driving the probe 2 to lift and lower. In this embodiment, the driving member for driving the probe 2 to lift and lower is a first lifting cylinder 3. The visual detection module is located above the probe test module, and the monitoring camera module is located on the side of the probe test module.
[0026] The conveying module includes an electric cylinder 4 and a fixture 5 located on the sliding table of the electric cylinder 4 for placing product 1. The electric cylinder 4 extends into the dark box 11 to transport product 1 placed on the electric cylinder 4 in the previous station into the dark box 11 for a lighting test. The fixture 5 includes a profiling part 6 and a tray 7 fixed on the profiling part 6. Fixing pins 8 and suction cups 9 are arranged on the profiling part 6. The suction cups 9 are connected to a vacuum generator 10. Product 1 is provided with pin holes corresponding to the fixing pins 8. When the fixing pins 8 are inserted into the pin holes, product 1 can be fixed while being positioned. A part of product 1 is placed on the profiling part 6 and fixed by the fixing pins 8 and the suction cups 9, and the other part is supported by the tray 7 to ensure the stable placement of product 1 on the fixture 5.
[0027] The light-tight box 11 includes a light-tight box body and a light-shielding cover 12 provided on the outer wall of the light-tight box body. The light-tight box body includes a light-tight box door 13 through which the product 1 loaded on the electric cylinder 4 passes. An opening is provided on the light-tight box door 13; a lifting door assembly is installed on the inner wall of the light-tight box door 13. The lifting door assembly includes a lifting door 14 and a driving member for driving the lifting door 14 to lift. In this embodiment, the driving member for driving the lifting door 14 to lift is a second lifting cylinder. A notch for avoiding the electric cylinder body is provided on the lifting door 14.

The electric cylinder 4 drives the fixture 5 and then drives the product 1 to sequentially pass through the light-shielding cover 12 and the lifting door 14 and enter the light-tight box 11. When the product 1 enters the predetermined position in the light-tight box 11, the lifting door 14 descends under the drive of the second lifting cylinder to block the light in the light-tight box 11; the first lifting cylinder 3 drives the probe 2 to descend, and the probe 2 is inserted into the test points on the PCB board. Whether the lamp beads are lit is detected by the CCD camera 16, and at the same time, monitoring is carried out by the monitoring camera 17; after the test is completed, the first lifting cylinder 3 drives the probe 2 to rise and reset, the second lifting cylinder drives the lifting door 14 to rise, the electric cylinder 4 drives the product 1 to move out of the light-tight box 11, and the material taking mechanism takes away the product 1 on the electric cylinder 4, and the product 1 is subjected to lighting tests in this cycle.
