[0002] Laptop computers need to undergo a series of inspections before leaving the factory, including key inspection, four-color brightness inspection, aging inspection, hinge inspection, etc. Only when laptops complete factory inspections can they meet the national production standards.

[0003] Factory inspection of notebooks is usually done manually. The assembled notebooks move slowly along the transportation line, and the buttons, screens, hinges and other inspections are completed at different workstations. The screen of the laptop is inspected using built-in inspection software. The inspection software will display various colors in turn, and the staff can observe whether there are dead pixels or bright spots on the screen. The state stipulates that more than three dead pixels do not meet the production standards.

[0004] The screen detection of a laptop is usually completed by the detection software inside the laptop, but the detection capability of the detection software is limited. In order to better improve the inspection work of the laptop, the brightness, color difference, brightness of the backlit keyboard, and brightness of the illuminated logo on the back of the flip cover of the laptop screen are also required to be tested to improve the factory standards of the laptop.

[0049] Embodiment 2

[0050] Screen brightness test device, such as Fig.10 As shown, two groups of rotating seats 507 are rotatably connected with a lift cover plate 508, and one end of the lift cover plate 508 is connected with a driving component 509, a plurality of groups of suction cups 510 are installed on one side of the lift cover plate 508, and a second sensor 511 is installed on one side of the lift cover plate 508. By setting the lift cover plate 508 connected with the driving component 509, the lift cover plate 508 can adjust the angle of the screen of the product 10. When the product 10 is transported from the coarse positioning mechanism 2, the screen of the product 10 is less than ninety degrees, which will affect the detection of the second colorimeter 8. Because the lift cover plate 508 can not only help adjust the screen of the product 10 to ninety degrees, but also rotate the screen of the product 10 multiple times to detect the rotation axis of the product 10.

[0051] The working principle of the utility model is as follows: the top of the base 1 includes a protective equipment cover 9, and the products 10 are installed in the pallet 11. Multiple groups of pallets 11 are placed on the roller assembly line 201 for transportation. When the pallet 11 is transported to the bottom of the barcode scanner 204, the barcode scanner 204 identifies and starts the positioning mechanism 202. The positioning mechanism 202 is mainly driven by a cylinder. The positioning mechanism 202 pushes the pallet 11 to one side of the roller assembly line 201, and then the blocking cylinder 203 blocks the pallet 11 from moving forward. Then the surface light 206 above the pallet 11 takes a picture of the product 10 and records the model data of the product 10. The camera 205 helps the surface light 206 focus the light source.

[0052] Next, the robot arm 3 drives the conveying mechanism 4 to work, and the first cylinder 402 is extended and retracted, and the distance between the two sets of guide rail sliders 404 can be adjusted by rotating the adjusting pulley 403, so that the two sets of guide rail sliders 404 can expand and contract at the bottom of the robot arm connecting mechanism 401, and the conveying mechanism 4 grabs a group of products 10, wherein the first sensor 405 works to identify and ensure that the conveying mechanism 4 successfully completes the grabbing work.

[0053] Next, the conveying mechanism 4 places the grabbed product 10 on the second mounting plate 504, and the second cylinder 506 works to drive the two groups of clamping components 505 to approach each other, so that the two groups of clamping components 505 clamp the product 10. At this time, the screen of the product 10 is in an open state, and then the driving component 509 works to drive the flip cover plate 508 to rotate a certain angle, so that the flip cover plate 508 fits the flip cover of the product 10, and is recognized by the second sensor 511. The suction cup 510 works to adsorb the flip cover of the product 10 on one side of the flip cover plate 508, and then the driving component 509 repeatedly rotates and works, driving the flip cover plate 508 to rotate repeatedly, thereby testing the shaft performance of the product 10. After the shaft performance detection structure, the driving component 509 works to ensure that the screen of the product 10 is in a ninety-degree state, and then the suction cup 510 stops working.

[0054] Next, the slide rail mechanism 501 works to drive the first mounting plate 502 to adjust its position, and the electric telescopic rod 503 works to adjust the height of the second mounting plate 504, thereby adjusting the position of the product 10 in the horizontal direction and the vertical direction, so that the first colorimeter 7 can detect the brightness of the backlight keyboard of the product 10, and the second colorimeter 8 can detect the screen brightness and color difference of the product 10. After the detection is completed, the robot arm 3 can also transfer and send out the product 10.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model.
