Specifically, the inclined section is designed according to the size of the vehicle-mounted display screen 29, which is convenient for pressing against the vehicle-mounted display screen 29 and controlling the transportation.

[0034] The driving component includes a slide bar 20 fixedly connected to both sides of the inner wall of the shell 19. The two slide bars 20 are vertically slidably connected to a movable frame 21. The longitudinal section of the movable frame 21 is U-shaped. A plurality of active rollers 25 are evenly connected to the movable frame 21 for rotation. The outer wall of the active roller 25 is evenly provided with rubber protrusions. A chain 26 is engaged with one side of the plurality of active rollers 25.

[0035] A bracket 22 is fixedly connected to the top of the movable frame 21, and a motor 23 is fixedly connected to the top of the bracket 22. A spring 24 is connected to the top of the motor 23 and the inner wall of the shell 19 to elastically push the entire movable frame 21 downward, so that the active roller 25 abuts against the top of the vehicle-mounted display screen 29, and relies on the rubber protrusion on the active roller 25 to drive the vehicle-mounted display screen 29 to slide horizontally along the driven roller 16. The output shaft of the motor 23 is fixedly connected to the driving gear 28, and the driving gear 28 is meshed with the chain 27.

[0036] Specifically, each active roller 25 is provided with a protrusion at the coaxial position, the protrusion is rotatably connected to the movable frame 21, and a gear 1 is fixedly connected to one side of the protrusion located inside the movable frame 21.

[0038] The implementation principle of an aging detection system for vehicle-mounted screen production in the embodiment of the present application is as follows:

[0039] In the vehicle screen placement area, the vehicle display screen 29 is manually placed in order on the bottom positioning plate 15 between the two clamping plates 12. There is no need to manually adjust the state of the vehicle display screen 29. After all the vehicle display screens 29 are placed on the bottom positioning plates 15, the two motors 16 are synchronously controlled to connect the screw 7 with the threaded sleeve 8, so that the entire frame 9 is synchronously moved down vertically with the connecting block 10, so that multiple shells 19 are moved down synchronously. When the shell 19 moves down, the connecting arms 18 on both sides and the slide bar 17 are driven to move down first along the vertical section of the guide slot 14, and the active roller 2 is used first to move down. 5 pairs of top ends of the vehicle-mounted display screens 29 abut against each other, so that the vehicle-mounted display screen 29 remains flat under the abutment, and as the shell 19 continues to move downward, the slide bar 17 slides to the inclined section and continues to move downward, so that the two splints 12 slide synchronously inward along the horizontal slide groove 5 to the center, so that the inner walls of the two splints 12 push the vehicle-mounted display screen 29 and center it, and then synchronously drive multiple motors 23 to drive multiple active rollers 25 to rotate, and use the rubber protrusions on the active rollers 25 to use friction to push the vehicle-mounted display screen 29 to slide along the driven rollers 16 toward the partition 2, so that the vehicle-mounted display screen 29 is plugged into the connection plug at the specified position.

[0040] After all the installation, positioning and plugging are completed synchronously, the moving wheels set at the bottom are used to drive the device body to move to the detection area to implement tests such as temperature, humidity, signal transmission and power supply, and mark the vehicle-mounted display screen 29 one by one according to the test results and send them to the terminal.

[0041] After the test is completed, the motor 2 23 can be driven in reverse to release the connection between the vehicle display screen 29 and the connecting plug, and the frame 9 can be driven upward by the motor 1 6 at the same time, so that the slide bar 17 moves up along the guide groove 14 and releases the contact between the bottom end of the active roller 25 and the vehicle display screen 29, making it convenient to take it out later.

[0042] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
