[0031] This part is based on Figure 1-8The working process expressed in 11 and 12 is: in the process of continuous production and manufacturing of Mini LED display screens, in order to facilitate the lamination treatment of the surface of the initially manufactured Mini LED display screen, it is helpful to prevent the surface of the Mini LED display screen from being contaminated with dust and impurities when it is transported to the next workstation, thereby ensuring the overall quality of the Mini LED display screen. When in use, the output shaft of a first motor is fixedly connected to the right side of the rotating rod 103 through a coupling, and the first motor is fixedly connected to the right side of the horizontal frame 101 through bolts. Driving the first motor can rotate the rotating rod 103. At this time, the batch-produced Mini LED display screens are placed one by one on each square plate 203, and the four corners of the lower surface of the Mini LED display screen are adsorbed and limited by the adsorption pads 204 at the four corners of each square plate 203. The first motor is driven to rotate the rotating rod 103, so that the right-angle frame 201 connected to the right half of the lead screw of the rotating rod 103 moves toward the right side, and simultaneously drives multiple Mini LED display screens with adsorption limits to move synchronously, and makes any Mini The LED display screen is moved to the middle position of the support frame 401, and then one end of the covering film 503 wound on the long pulley 502 is pulled out by the staff and covered on the surface of the Mini LED display screen located in the middle position of the support frame 401, so that the staff can cut and cover the covering film 503 according to the size of the Mini LED display screen, thereby forming a continuous pre-protection work of the Mini LED display screen. In the process of continuous production and manufacturing of the Mini LED display screen, it is convenient to coat the surface of the initially manufactured Mini LED display screen, which helps to prevent the surface of the Mini LED display screen from being contaminated with dust and impurities when transporting it to the next workstation, thereby ensuring the overall quality of the Mini LED display screen. The covering film 503 is made of plastic wrap material.

[0032] Each of the adsorption pads 204 is made of rubber material with a concave middle portion.

[0033] This part is based on Figure 1-8 The working process expressed in 11 and 12 is: each adsorption pad 204 is made of rubber material with a concave middle part, so that the placed display screen can be stably adsorbed and placed by utilizing the concave shape of the middle part and the rubber material, so that the display screen will not be at risk of falling and tipping over when the covering film 503 is initially attached.

[0034] The upper side of the support frame 401 is slidably connected to a sliding frame 402, the front side of the sliding frame 402 is rotatably connected to a rotating rod 403, the left side of the rotating rod 403 is fixedly connected to a rotating head 406, one end of the coating film 503 is overlapped on the rotating rod 403, and a square hole is provided in the middle of the sliding frame 402.

[0035] The top right side of the support frame 401 is rotatably connected with a lead screw 404 , and the lead screw 404 is drivingly connected to the right lead screw of the sliding frame 402 .

[0036] This part is based on Figure 1-8 The working process expressed in 11 and 12 is: the coating film 503 can be automatically unfolded when it can be unfolded and the wrinkles after unfolding can be reduced, which is helpful for the subsequent cutting of the coating film 503 and covering it on the display screen. When in use, the output shaft of a second motor is fixedly connected to the front side of the screw 404 through a coupling, and the second motor is fixedly installed on the support frame 401 by bolts. The second motor is driven to rotate the screw 404, so that the sliding frame 402 connected to the screw 404 can move forward and backward. Before the sliding frame 402 moves forward and backward, the staff will The covering film 503 is pulled out from the long pulley 502 and overlapped on the rotating rod 403. When the rotating rod 403 moves following the sliding frame 402, the rotating rod 403 stretches and unfolds the covering film 503, and reduces wrinkles during the unfolding, thereby preventing wrinkles from being generated when the covering film 503 is subsequently attached to the surface of the display screen. Subsequently, the sliding frame 402 moves forward and backward to align the square hole in the middle with the display screen moving below, so that the covering film 503 can be automatically unfolded and the phenomenon of wrinkles after unfolding can be reduced, which is helpful for subsequently cutting the covering film 503 and covering it on the display screen.

[0037] The top of the support frame 401 is fixedly connected to an arch frame 405, and a lifting frame 601 is slidably connected to the arch frame 405. The bottom of the lifting frame 601 is fixedly connected to a cutting frame 602. The top of the lifting frame 601 is fixedly connected to the movable end of an electric push rod 603, and the fixed end of the electric push rod 603 is fixedly connected to the arch frame 405.

[0038] A blade is arranged around the bottom of the cutting frame 602 .

[0039] This part is based on Figure 1-12The working process expressed therein is: in order to facilitate cutting the unfolded covering film 503 along the square hole in the middle of the sliding frame 402 and adhering and covering the display screen on the square plate 203 at the corresponding position at the bottom, so that preventive coating work can be performed on multiple display screens in batches, when in use, the electric push rod 603 is driven to make the lifting frame 601 located at the movable end of the electric push rod 603 move downward, and then the cutting frame 602 located at the bottom of the lifting frame 601 uses the blades around its bottom to cut the unfolded covering film 503 along the square hole in the middle of the sliding frame 402, and the cut covering film 503 is covered on the display screen placed below by the descending of the cutting frame 602, and the shape of the cutting frame 602 is used to adapt to the size of the display screen, so that the unfolded covering film 503 is cut along the square hole in the middle of the sliding frame 402 and adhered and covered on the display screen on the square plate 203 at the corresponding position at the bottom, which helps to prevent the surface of the Mini LED display screen from being contaminated with dust and impurities when transporting it to the next station;

[0040] The width of the covering film 503 is greater than the width of the square hole in the middle of the sliding frame 402, so that the covering film 503 can cover the upper part of the middle square hole when unfolded, and the overall length of the cutting frame 602 is less than the overall width of the square hole in the middle of the sliding frame 402, so that the cutting frame 602 can press the covering film 503 and cut it, thereby driving the cut covering film 503 to pass through the square hole in the middle of the sliding frame 402, and further, the cut covering film 503 is pressed and attached to the surface of the display screen, and the overall cutting frame 602 is much larger than the size of the display screen, and after the cutting frame 602 covers the covering film 503, the covering film 503 follows the cutting size of the cutting frame 602 is also much larger than the size of the display screen, and when the cutting frame 602 moves downward and covers the display screen, no matter the position of the sliding display screen is biased towards any direction of its sliding direction, it can stably cover the surface of the display screen;

[0041] After a coating film 503 is cut, a worker can grab the rotating head 406 on the rotating rod 403 to rotate the rotating rod 403, so that the coating film 503 overlapped on the rotating rod 403 continues to be wound on the rotating rod 403, and the subsequent coating film 503 continues to be used for coating.

[0042] A feed rack 301 is fixedly connected to the left side of the transverse rack 101 , a belt conveyor 302 is installed on the upper side of the feed rack 301 , and a feed frame 303 is fixedly connected to the front side of the feed rack 301 .

[0043] The inner surface of the feeding frame 303 is polished.

[0044] This part is based on Figure 1-12The working process expressed therein is: when the Mini LED display screen produced by preliminary processing is connected and flows into the device, the production line of the Mini LED display screen produced by preliminary processing is connected to the belt conveyor 302. The belt conveyor 302 is a prior art product and will not be described in detail. Then, the belt conveyor 302 is driven to slide the produced Mini LED display screen into the feed rack 301, and move it to any square plate 203 below through the bottom opening of the feed frame 303. By analogy, the Mini LED display screens produced in batches fall into the square plate 203 to carry out subsequent coating work.

[0045] The structure shape of the feed frame 303 is conical, and the four sides are flat. A gentle slope is provided on the upper side of the interface with the belt conveyor 302, which can make the display screen flowing into the feed frame 303 slide more smoothly, and then slide down to the square plate 203 along the length direction of the display screen according to the bottom opening of the feed frame 303, so that the display screen is buffered according to the adsorption pads 204 at the four corners of the square plate 203, and the display screen is adsorbed on the surfaces of the four adsorption pads 204 and is in a horizontal state, ensuring the adsorption stability of the display screen, making the work of covering the coating film 503 more stable, and the overall size of the cutting frame 602 is larger than the size of the Mini LED display screen, so that the cut coating film 503 can be completely covered on the Mini LED display screen. On the LED display screen, the bottom opening of the feed frame 303 is rectangular, so that the two long sides of the display screen that slides in can slide out by leaning against the two long sides of the rectangular shape of the feed frame 303, so that the display screen can slide from the bottom opening of the feed frame 303 to the square plate 203 along the length direction. The overall size of the square plate 203 is smaller than the size of the display screen, so that the display screen can cover the entire area of ​​the square plate 203 when it slides. When the display screen slides, the adsorption pads 204 at the four corners of the square plate 203 cushion the display screen, and use the force of the display screen sliding to stably adsorb on the adsorption pads 204, so that the display screen can be placed more stably.

[0046] According to the process of manufacturing a Mini LED display screen by the Mini LED display screen manufacturing device, the process includes the following steps:

[0047] S1: docking the processed Mini LED display screen into the Mini LED display screen manufacturing device, and docking along the length direction of the Mini LED display screen production flow, so that the Mini LED display screen can enter the Mini LED display screen manufacturing device along its length direction;
