Description

Technical Field

[0001] The utility model relates to the technical field of LED display screen assembly, in particular to an LED display screen frame mounting device. Background Art

[0002] The existing common large-scale LED display screens are mainly made of substrates, LED unit screens and frames. The LED unit screens are arranged in a matrix and plugged into the substrate. The LED unit screens plugged into the substrate form a complete screen, and then the frame is encapsulated on the periphery of the screen to improve the strength of the entire display screen. Since each LED unit screen on the substrate can be installed and removed separately, the frame is actually used to improve the strength of the substrate body, and also provides safety protection for the substrate.

[0003] Currently, due to the large size of the baseboard, most existing frames are designed with a plug-in structure for the front and rear frames. When the front and rear frames are plugged in, an annular retaining groove is formed between them, which secures the baseboard. After the front and rear frames are plugged in to retain the baseboard in place, screws are used to fasten the front and rear frames together. Given the large size of the aforementioned baseboard, docking the baseboard with the front and rear frames is also difficult. Specifically, the existing docking method typically requires manually lifting the baseboard and placing it within the rear frame, and then manually lifting the front frame and snapping it into the rear frame. This installation method is not only inconvenient to align, but also labor-intensive.

[0004] To this end, the utility model provides a device for installing a frame of an LED display screen. Utility Model Content

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 3 The utility model provides a technical solution: a device for installing the frame of an LED display screen, comprising a base 1 and a frame assembly 4, wherein the frame assembly 4 comprises a front frame 41 and a rear frame 42 connected to the front frame 41 by snapping, wherein a snap hole is provided at the joint surface of the front frame 41, and an insertion shaft is fixedly provided at the joint surface of the rear frame 42, and the front frame 41 and the rear frame 42 are snapped together to form a complete frame.

[0022] In this technical solution, a positioning tray 2 and a lifting ring 3 are provided above the base 1. The positioning tray 2 is accommodated in the lifting ring 3. The positioning tray 2 is used to support the substrate covered with LED unit screens, and the lifting ring 3 is used to lift and control the lifting of the rear frame 42. In specific implementation, the bottom of the lifting ring 3 is fixedly connected to the upper end face of the base 1 through the lifting cylinder 101, and the bottom of the positioning tray 2 is fixedly connected to the upper end face of the base 1 through the pillar 102. When in use, the rear frame 42 is first placed on the top of the lifting ring 3, and then the substrate is placed on the positioning tray 2. The lifting ring 3 is controlled to rise to drive the rear frame 42 and the substrate to dock, which greatly reduces the difficulty of docking the rear frame 42 and the substrate, and has the advantage of labor-saving docking.

[0023] Furthermore, a column 9 is provided on one side of the lifting support ring 3, and the bottom of the column 9 is fixedly connected to the top of the base 1. A rotating arm 5 is provided on the top of the column 9, and a rotating shaft 6 is provided at the bottom of the rotating arm 5. The rotating shaft 6 is the output shaft of the control motor, and the bottom of the rotating shaft 6 is connected to a four-sided clamp group 8 through a lifting control rod 7. The lifting control rod 7 can be an electric push rod or a cylinder. When the rotating arm 5 rotates, it can drive the four-sided clamp group 8 to move to the top of the positioning tray 2. The function of the four-sided clamp group 8 is to clamp the substrate and the front frame 41. The clamping parts are the four sides of the substrate and the front frame 41. The rotation of the rotating arm 5 cooperates with the lifting function of the lifting control rod 7, which makes the loading of the substrate and the front frame 41 more labor-saving, and makes the docking of the substrate and the front frame 41 with the rear frame 42 more convenient and efficient.

[0024] Specifically, the four-sided clamp group 8 includes a hanging plate 81 and a clamping cylinder 82. The top of the hanging plate 81 is fixedly connected to a transfer shaft 811 fixedly connected to the rotating shaft 6. When the rotating shaft 6 rotates, the hanging plate 81 is driven to rotate by the transfer shaft 811. The bottom of the hanging plate 81 is fixedly connected to four positioning plates 812 that are evenly distributed axially relative to the transfer shaft 811. The clamping cylinder 82 is fixedly provided on the positioning plate 812. The action end of the clamping cylinder 82 is fixedly connected to a clamping plate 821. When clamping the substrate, the two opposite clamping plates 821 clamp the two sides of the substrate, and the other two opposite clamping plates 821 clamp the other two sides of the substrate. After being clamped, the substrate is in a centered state relative to the hanging plate 81.

[0025] In this embodiment, four corner blocks 31 are fixedly connected to the top of the lifting support ring 3. The four corner blocks 31 respectively cooperate with the four corners in the rear frame 42. The corner blocks 31 are round rod structures. After the rear frame 42 is placed on the lifting support ring 3, it will be limited and fixed by the corner blocks 31. In other words, the corner blocks 31 play a role in accurately positioning the rear frame 42.

[0026] In this embodiment, a side protective rubber pad 8211 is bonded to one side of the clamping plate 821 . The side protective rubber pad 8211 protects the substrate and the outer side wall of the front frame 41 to prevent the substrate and the outer side wall of the front frame 41 from being scratched.

[0027] In this embodiment, a support plate 813 located on one side of the positioning plate 812 is welded to the bottom of the suspension plate 81. A support sleeve 8131 is fixedly provided on the support plate 813 and is slidably connected to the action axis of the clamping cylinder 82. The function of the support sleeve 8131 is to support the clamping cylinder 82 and improve the positioning strength of the clamping cylinder 82 on the suspension plate 81.

[0028] Furthermore, a pressure plate 8212 near the top is fixedly connected to one side of the splint 821, and a lower protective rubber pad 82121 is bonded to the bottom of the pressure plate 8212. The function of the pressure plate 8212 is to insert the insertion shaft on the front frame 41 into the card hole on the rear frame 42 when it moves downward.

[0029] When in use, first place the substrate and the front frame 41 on their respective shelves close to the device, so that the substrate and the front frame 41 are in a position where the four-sided clamp group 8 can pass through, and then manually place the lightweight rear frame 42 on the lifting support ring 3, and the inner corner of the rear frame 42 is limited by the corner block 31, and then control the rotating arm 5 to rotate. When the four-sided clamp group 8 is above the substrate, control the rotating arm 5 to stop rotating, and control the lifting control rod 7 to drive the hanging plate 81 to descend. When the clamping plate 821 is located on the outside of the substrate, control the clamping cylinder 82 to act synchronously. The substrate is clamped by the surrounding clamping plates 821 and then lifted by the lifting control rod 7, and then control the rotating arm 5 to rotate so that the substrate is located directly above the rear frame 42, and then control the substrate to descend into the step groove in the rear frame 42. Then withdraw the four-sided clamp group 8, and then drive the front frame 41 to the top of the substrate in the above manner, control the lifting control rod 7 to descend, and the pressing plate 8212 presses the front frame 41 onto the rear frame 42, thereby completing the assembly of the substrate, the front frame 41 and the rear frame 42.

[0030] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
