When in use, the display screen 200 to be tested is installed on the carrier module 4. Open the two-position two-way valve and the gas path is connected. Intake air into the Z-direction cylinder barrel 2171 and push the Z-direction piston 2172 to move upward. The Z-direction piston 2172 pushes the Z-direction piston rod 2173 to move upward. The end of the Z-direction piston rod 2173 away from the Z-direction piston 2172 pushes up the end of the upper clamping block 213 close to the test module 3. The elastic member 216 is in a compressed state. The upper clamping block 213 drives the indenter 215 to lift up. The first air pipe 2114 takes air into the cylinder barrel 2111 into the X direction, and the second air pipe 2115 exhausts air to the outside, so that the X direction cylinder slider 210 slides away from the test module 3. Connect the connecting female end 302 on the test module 3 to the connecting male end 218 on the adjustment module 2. Adjust the first adjusting bolt 2043 to push the Y-direction slider 202 to slide. This makes the first detection point 303 of the test module 3 correspond to the second detection point 2001 on the display screen 200 in the Y direction. Then tighten the first fixing screw 205 so that the Y-direction slider 202 remains unchanged in the Y-direction. Then adjust the second adjusting bolt 2083 to push the X-direction slider 206 to slide. This makes the first detection point 303 of the test module 3 correspond to the second detection point 2001 on the display screen 200 in the X direction. Then tighten the second fixing screw 209 so that the X-direction slider 206 remains unchanged in the X-direction. The second air pipe 2115 enters X into the cylinder barrel 2111, and the first air pipe 2114 exhausts outward. This makes the X-direction cylinder slider 210 slide toward the test module 3. Close the two-position two-way valve, the gas path is not connected. The third air pipe 2174 exhausts outward, and the Z-direction piston 2172 moves downward. The indenter 215 drops, and the indenter 215 presses the first detection point 303 and the second detection point 2001 tightly. The first aviation socket 304 and the second aviation socket 101 are connected with a connecting wire, the control device 5 is turned on, and the lighting test of the display screen 200 on the lighting fixture 110 is started.
When changing the display screen 200 of different specifications for testing, open the two-position two-way valve and the gas path is connected. Intake air into the Z-direction cylinder barrel 2171 and push the Z-direction piston 2172 to move upward. The Z-direction piston 2172 pushes the Z-direction piston rod 2173 to move upward. The end of the Z-direction piston rod 2173 away from the Z-direction piston 2172 pushes up the end of the upper clamping block 213 close to the test module 3. The elastic member 216 is in a compressed state. The upper clamping block 213 drives the indenter 215 to lift up. The first air pipe 2114 takes air into the cylinder barrel 2111 into the X direction, and the second air pipe 2115 exhausts air to the outside, so that the X direction cylinder slider 210 slides away from the test module 3. Remove the original display screen, replace with a new display screen, and install the test module 3 matching the new specification display screen on the adjustment module 2.
In summary, the lighting fixture 110 of this embodiment mounts the display screen 200 on the carrier module 4. The test module 3 corresponding to the display screen 200 is installed on the adjustment module 2. The first detection point 303 of the test module 3 is correspondingly connected to the second detection point 2001 on the display screen 200 through the adjustment module 2. This can improve the alignment accuracy of the first detection point 303 and the second detection point 2001 and improve the detection efficiency.
The lighting fixture 110 of this embodiment can be adjusted accurately and quickly switch display screens 200 of different specifications for lighting testing. This reduces the replacement time of the lighting fixture 110 during the lighting test of the display screens 200 of different specifications and improves the replacement efficiency. This enhances the versatility of the lighting fixture 110 and improves the repetitive utilization of the lighting fixture 110. This reduces the cost of the lighting fixture 110. This reduces the types of lighting fixtures 110 and reduces the occupation of the company's inventory space. This reduces the production cost of the enterprise.
