Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In the first embodiment, the conveying and loading mechanism includes a backlight conveyor line body 2 fixedly mounted on the top of the backlight conveyor line bracket 1, the backlight conveyor line body 2 includes a driving motor 101 arranged on one side, and a speed regulator 102 fixedly connected to the backlight conveyor line body 2 is arranged on one side of the driving motor 101, so as to facilitate the use of the driving motor 101 to drive the backlight conveyor line body 2 to rotate and convey.

[0022] Among them, the speed of the driving motor 101 can also be adjusted by the speed regulator 102, a backlight source 103 is arranged inside the backlight conveyor line body 2, and a transparent belt 104 is movably connected to the top of the backlight conveyor line body 2 to facilitate light transmission, a tracking encoder assembly 3 is arranged on the top of the backlight conveyor line body 2, and a panoramic camera bracket 4 is fixedly installed on one side of the backlight conveyor line bracket 1.

[0023] In this embodiment, a panoramic camera body 5 is fixedly installed on one side of the panoramic camera bracket 4, a robot bracket 6 is arranged on one side of the backlight conveyor line body 2, a four-axis horizontal robot 7 is arranged on the top of the robot bracket 6, a vacuum solenoid valve 601 is arranged on one side of the robot bracket 6, and a vacuum suction cup 602 is arranged on one side of the four-axis horizontal robot 7, so that the vacuum solenoid valve 601 can drive the vacuum suction cup 602 to perform adsorption.

[0024] In the second embodiment, the tracking encoder assembly 3 includes a linear guide rail 401 fixedly mounted on the top of the panoramic camera bracket 4, a coupling 403 is movably connected to one side of the linear guide rail 401, an encoder body 402 is arranged on one side of the coupling 403, and a rubber-coated wheel 404 is arranged on the side of the coupling 403 away from the encoder body 402.

[0025] Among them, the encoder body 402 is connected to the rubber-coated wheel 404 through a coupling 403, and the rubber-coated wheel 404 is movably installed on the linear guide rail 401 of the Z axis, so that the rubber-coated wheel 404 and the backlight conveyor line body 2 can be closely contacted together by gravity. When the transparent belt 104 rotates, the rubber-coated wheel 404 is driven to rotate, and the encoder body 402 automatically calculates the rotation data.

[0026] It should be noted that the non-stop dynamic feeding mechanism, through the setting of the transmission feeding mechanism, makes it possible for the conveyor line to completely stop without having to stop, which can greatly improve production efficiency and grasping accuracy. The original feeding method uses a cylinder to mechanically calibrate the LCD screen at the end of the conveyor line, and the accuracy can only reach ±1 mm. The new method adopts visual capture. After the panoramic camera body 5 captures the LCD screen, the number and coordinate information of the LCD screen are calculated, and the tracking encoder component 3 installed on the backlight conveyor line body 2 continuously records the operation data of the backlight conveyor line body 2, with an accuracy improved to ±0.2 mm. The four-axis horizontal robot 7 ends the synchronous action with the conveyor line, and the LCD screen is transported to the next process, and the cycle is completed.

[0027] The working principle of the above embodiment is:

[0028] The non-stop dynamic feeding mechanism, the tracking encoder assembly 3 is installed above the backlight conveyor line body 2, the encoder body 402 is connected to the rubber-coated wheel 404 through the coupling 403, the rubber-coated wheel 404 is installed on the linear guide 401 of the Z axis, and the rubber-coated wheel 404 and the backlight conveyor line body 2 are in close contact with each other by gravity. When the transparent belt 104 rotates, the rubber-coated wheel 404 is driven to rotate, and the encoder body 402 automatically calculates the rotation data, the backlight conveyor line body 2 is docked with the upstream conveyor line, and the liquid crystal display automatically flows from the upstream conveyor line to the backlight conveyor line body 2, and the backlight conveyor line body 2 continues to operate. After the panoramic camera body 5 above captures the liquid crystal display, the number and coordinate information of the liquid crystal display are calculated, and the tracking encoder assembly 3 installed on the backlight conveyor line body 2 continuously records the operation data of the backlight conveyor line body 2;

[0029] The four-axis horizontal robot 7 moves to the top of the LCD screen according to the coordinate data fed back by the camera and the rotation data of the backlight conveyor line body 2 fed back by the tracking encoder component 3. The Z axis of the four-axis horizontal robot 7 descends, and the X and Y axes maintain the same speed and direction as the backlight conveyor line body 2, and are completely synchronized. The four-axis horizontal robot 7 opens the vacuum solenoid valve 601 and drives the vacuum suction cup 602 to suck the LCD screen and lift it to the specified height. After reaching the specified height, the four-axis horizontal robot 7 ends the synchronous action with the conveyor line and transports the LCD screen to the next process. The cycle is completed. During the above whole process, the backlight conveyor line body 2 is in continuous operation, which improves the production efficiency and increases the practicality of the device.
