Even if the installers reduce the installation speed, it cannot effectively avoid the edge of the display from being damaged, and the installation efficiency will be greatly reduced. According to the light-emitting principle of the LED display, each small lamp bead needs to be arranged in an array and the distance between the lamp beads should not be too large. The lamp beads are encapsulated on the unit board, so seamless splicing is required during splicing. Therefore, it is difficult to reduce the damage to the edge of the LED module panel from the installation process.

Specifically, a shell is added to the outside of the LED display screen, and a protection cover is added to the outside of the shell.

[0028] It should be further explained that the drawings and implementation modes of the present invention mainly describe the concept of the present invention. On the basis of this concept, the specific forms and settings of some connection relationships, positional relationships, power mechanisms, power supply systems, hydraulic systems and control systems may not be fully described. However, on the premise that those skilled in the art understand the concept of the present invention, those skilled in the art can implement the above-mentioned specific forms and settings in a well-known manner.

[0029] When an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or indirectly connected to the other element.

[0030] The directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself. The directions or positional relationships indicated by the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" are based on the directions or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0031] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure.

According to the generation requirements, the adjacent optical fiber spacing in the optical fiber group located at the annular mold is 0, and the maximum adjacent optical fiber spacing at the rest of the optical fiber group is 1mm. After the mold cutting block 4 is snapped, the glue injection mechanism 6 injects glue into the annular mold to solidify the optical fiber.

[0037] like Figure 1 to Figure 2 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0038] The arrangement mechanism 3 includes a tooth inserting device 31, a feeding conveyor belt 32 and a manipulator 33; a plurality of tooth inserting devices 31 are provided, and the tooth inserting devices 31 are used to be inserted into the optical fiber group at intervals to form an optical fiber array; the feeding conveyor belt 32 is arranged at the feeding end of the conveying mechanism 2, and the feeding conveyor belt 32 is used to place a plurality of tooth inserting devices 31; the manipulator 33 is arranged on the frame 1, and the manipulator 33 is used to insert the tooth inserting device 31 on the feeding conveyor belt 32 into the optical fiber group.

[0039] Specifically, in this embodiment, the number of optical fiber groups is 36*36, and the inserting teeth 31 are 36-tooth inserting plates, which can be adjusted according to production requirements. In this embodiment, there are two groups of manipulators 33, which are respectively located on both sides of the conveying mechanism 2, and the inserting teeth 31 inserted into the optical fiber groups by the two groups of manipulators 33 are arranged perpendicular to each other.

[0040] The robot 33 grabs the inserting teeth 31 on the feeding conveyor belt 32 and inserts them into the optical fiber group, so that the optical fiber arrangement efficiency is higher and the horizontal and vertical positioning of the optical fiber is completed.

[0041] like Figures 1 to 3 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0042] The mold material picking and fastening mechanism 5 includes a mold conveyor belt 51, a moving rotating component 52 and an electromagnetic suction component 53; the mold conveyor belt 51 is arranged on the frame 1, and the mold conveyor belt 51 is used to place and transport the mold cutting block 4; the moving rotating component 52 is arranged on the frame 1; the electromagnetic suction component 53 is arranged on the moving rotating component 52; the moving rotating component 52 is used to drive the electromagnetic suction component 53 to move and rotate, so that the electromagnetic suction component 53 can suck up the mold cutting block 4 on the mold conveyor belt 51 and fasten it to the optical fiber group.

[0043] In this embodiment, the annular mold can be divided into three mold cutting blocks 4, or can be divided into two or four blocks. The number of the mold material taking and locking mechanisms 5 is consistent with the number of the divided mold cutting blocks 4.

[0044] refer to Figure 4 and Figure 5 Specifically, in this embodiment, the annular mold is divided into three parts, consisting of two side parts and a top part, and the two side parts include the bottom part.

[0045] The moving and rotating assembly 52 drives the electromagnetic suction assembly 53 to move and rotate, so that the electromagnetic suction assembly 53 can absorb the mold cutting block 4 on the mold conveyor belt 51 and buckle it onto the optical fiber group at the same time.

[0046] like Figure 6 and Figure 7 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0047] The movable rotating assembly 52 includes a vertical linear module 521, a horizontal linear module 522, a first rotating motor 523, a first rotating member 524 and a second rotating motor 525; the vertical linear module 521 is installed on the frame 1; the horizontal linear module 522 is installed on the vertical linear module 521; the first rotating motor 523 is installed on the horizontal linear module 522; the vertical linear module 521 and the horizontal linear module 522 realize the XY axis movement of the first rotating motor 523; the first rotating member 524 is installed on the output shaft of the first rotating motor 523; the second rotating motor 525 is installed on the electromagnetic suction assembly 53, and the output shaft of the second rotating motor 525 is fixed on the first rotating member 524; the first rotating motor 523 and the second rotating motor 525 are arranged perpendicular to each other.

[0048] The vertical linear module 521 and the horizontal linear module 522 realize the XY axis movement of the electromagnetic suction component 53, and the first rotary motor 523 and the second rotary motor 525 realize the rotation of the electromagnetic suction component 53 in two directions, so that the fastening of the mold cutting block 4 is more efficient and accurate.

[0049] like Figure 6 to Figure 7As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0050] The electromagnetic suction component 53 includes a base plate 531, an electromagnet 532, an elastic telescopic part 533 and a push-out part 534; the base plate 531 is installed on the movable rotating component 52; the electromagnet 532 is located on the outer side of the base plate 531, and the electromagnet 532 is fixed to the base plate 531 through a connecting rod; the elastic telescopic part 533 is installed on the base plate 531, and the electromagnet 532 is located on the side of the elastic telescopic part 533 away from the base plate 531; the push-out part 534 is arranged on the side of the elastic telescopic part 533 away from the base plate 531, and protrudes from the electromagnet 532.

[0051] Specifically, the ejecting member 534 is a roller, and there are at least two ejecting members 534 , which are symmetrically arranged on both sides of the electromagnet 532 .

[0052] When the electromagnetic suction component 53 moves to the mold conveyor belt 51, the electromagnet 532 is set opposite to the mold cutting block 4, and the electromagnet 532 is energized to suck the mold cutting block 4 tightly. At this time, the ejection member 534 is squeezed by the mold cutting block 4, causing the elastic telescopic member 533 to shrink. When the mold cutting block 4 moves to the optical fiber group for buckling, the electromagnet 532 is powered off, and the elastic telescopic member 533 is reset, so that the ejection member 534 pushes the mold cutting block 4 onto the optical fiber group and separates from the electromagnet 532, thereby achieving a higher degree of automation and efficiency.

[0053] Specifically, in this embodiment, the elastic telescopic member 533 includes a movable plate 5331, a telescopic rod 5332 and a plurality of springs 5333. The telescopic rod 5332 is connected between the bottom plate 531 and the movable plate 5331. There are four springs 5333, which are respectively located at the four corners of the bottom plate 531 and the movable plate 5331 to balance the force exerted by the ejection member 534 on the mold cutting block 4.

[0054] like Figure 1 and Figure 3 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0055] The glue injection mechanism 6 includes a glue injection linear module 61 and a glue injection gun 62; the glue injection linear module 61 is arranged on the frame 1 and is located on one side of the conveying mechanism 2; the glue injection gun 62 is arranged on the glue injection linear module 61, and a glue injection hole 41 for inserting the end of the glue injection gun 62 is opened on the mold cutting block 4.

[0056] The glue injection linear module 61 drives the glue injection gun 62 to move toward or away from the glue injection hole 41 on the mold cutting block 4, and the structure is simple and efficient.

[0058] The conveying mechanism 2 adopts a sprocket chain type conveying, and a plurality of limit frames 21 are arranged on the outer ring of the chain, and the optical fiber group passes through the limit frames 21. Further, after the mold cutting block 4 is buckled, the two sides of the mold cutting block 4 are in contact with the inner wall of the limit frame 21.

[0059] The limiting frame 21 can limit the conveyance of the optical fiber group and the mold cutting block 4 after being fastened, thereby improving the conveyance stability of the optical fiber array as a whole.

[0060] like Figures 1 to 3 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0061] A limiting pipe 22 is arranged at the rear of the conveying mechanism 2, and the optical fiber group after glue injection passes through the limiting pipe 22; the side and top of the limiting pipe 22 are rotatably connected to a row of limiting wheels 23, and the inner end of the limiting wheel 23 abuts against the outer surface of the mold cutting block 4.

[0062] Since it takes some time for the glue to solidify after injection, the limiting pipe 22 can guide and limit the optical fiber array being solidified, and the limiting wheel 23 can limit the annular mold and reduce friction to ensure the transportation stability of the optical fiber array.

[0063] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
