Technical Field

The utility model relates to a LED display device technical field especially relates to a structure and the manufacturing of the LED display screen body that tensile bonding board bore.

Background

Under the continuous development and promotion of 'Chinese manufacturing', the LED display screen chassis is increasingly pursuing to improve the splicing effect, save materials, save manual work and machine processing time and strive to reduce the cost under the condition of meeting the strength requirement. This requires continuous improvement in the structural design of LED displays, development and adoption of techniques and processes that have not been or have not been applied in large quantities thereto, such as the use of bonding, calendering and stretching techniques, in-line automated processing, and the like.

Chinese patent document CN207217015U discloses "LED display screen box", and fig. 1 (i.e. original fig. 3) is a schematic diagram of an exemplary embodiment of the solution. Referring to fig. 1, the front part of the frame body of the box body is provided with a plurality of LED module mounting frames arranged in a matrix manner by a plurality of connecting rod bodies which are arranged in a criss-cross manner, the rear part of the frame body is provided with a door, one side of the door is hinged with the frame body by an inserting and rotating structure, and the door is mounted on the frame body. The box edges and the box corners are complex in shape and difficult to use automatic machining and machine electric welding, and the design structure of the typical sheet metal case is obviously suitable for the manufacturing process of manual successive flanging and manual electric welding, so that the labor cost cannot be saved. Moreover, manual hemming and electric welding have their disadvantages, such as time and labor consumption, poor precision, polishing and surface treatment (painting, powder spraying, oxidation, etc.) after welding, which affect the manufacturing precision and efficiency.

Chinese patent document CN205194244U discloses an LED die-casting aluminum box, and the technical scheme considers that the problems of unreasonable structural design … …, poor box strength, heavy box, complex production and processing technology, high production and manufacturing cost and the like of the traditional sheet metal box exist, so that the scheme adopts the die-casting aluminum box to realize light weight, reasonable structural design and high support strength, adopts casting one-step forming and can realize box manufacturing through turning and milling technologies, thereby saving a large amount of production such as sheet metal machining, welding and the like, and effectively reducing the production and manufacturing cost. However, with the die-casting aluminum box, in order to ensure the die-casting quality, the effects of reducing the thickness, reducing the weight and increasing the strength are still insufficient due to the limitations of the die and the die-casting process, and meanwhile, the problems of long time consumption, high cost, easy size limitation of processing equipment and the like caused by the use of die-casting and turning and milling processes exist, and the splicing effect, the manufacturing efficiency and the production and manufacturing cost of the die-casting aluminum box still have room for improvement.

Chinese patent document CN209525865U discloses "LED display screen box, LED display screen box assembly and LED display screen", and this technical scheme considers that "a plurality of LED display screen boxes, on-the-spot concatenation forms LED display screen box group, can have the segment difference between … … adjacent two LED display screen boxes, and then leads to the lamp face of LED display screen to have the unevenness phenomenon, appears the dark line problem even, influences the user and uses and experience good feeling. Therefore, the scheme adopts a fine adjustment structure on the die-cast aluminum box body shown in the figure, and … … is used for fine adjustment of the installation flatness of the box body by controlling the length of the fine adjustment structure extending out of the installation hole. However, this obviously increases the complexity and production cost of the LED display screen structure. From experience in the industry, whether the metal plate box body or the die-casting aluminum box body is spliced, the cost of a lock catch or a bolt and an electric connector is increased, and the phenomenon that the lamp surface of the LED display screen is uneven is possibly caused. Therefore, the splicing is reduced, and the cost can be obviously reduced and the splicing effect can be improved by adopting the screen body without splicing or with few splices.
