Description

Technical Field

[0001] This utility model relates to the field of LED display module production technology, and in particular to a module bottom shell and edge structure and an assembly positioning fixture. Background Technology

[0002] With advancements in technology, expansion of application areas, and changes in market demand, LED outdoor displays are no longer limited to large-pitch products; there is a growing demand for small-pitch LED outdoor displays that achieve high-definition display. To meet waterproofing requirements, the design of LED outdoor displays typically embeds the LED board into the base shell. When the LED pitch of the display is small, a very thin base shell needs to be formed to meet the LED pitch requirements when splicing the cabinets. However, in the actual injection molding process, the very thin sidewalls make sidewall forming difficult. Therefore, a separate manufacturing method is used for the base shell and the edge guards, which are then assembled.

[0003] Currently, the assembly of the base shell and the flange is generally done by adhesive bonding. Adhesive is injected at the connection between the flange and the base shell to form an adhesive layer, thereby fixing the base shell and flange in place, as shown in Chinese patent CN210110219U. However, because the flange wall is relatively thin, adhesive bonding results in poor assembly stability between the base shell and the flange. Furthermore, the flange's thinness makes it prone to deformation, leading to poor assembly quality. Additionally, the fluidity of the adhesive causes it to flow to the side walls of the base shell and flange, requiring scraping after curing. This reduces assembly efficiency and makes assembly inconvenient. Therefore, to address these issues, it is necessary to improve the structure of the base shell and flange and the assembly tooling. Utility Model Content

[0004] The purpose of this utility model is to provide a module bottom shell and edge structure and an assembly positioning fixture that provide good assembly stability and prevent deformation during assembly, thereby improving assembly quality.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] Please see Figure 1 and Figure 2 A module bottom shell and edge guard structure includes a bottom shell body 100 and an edge guard strip body 200. Both the bottom shell body 100 and the edge guard strip body 200 are square in shape, and the size of the edge guard strip body 200 corresponds to the size of the bottom shell body 100. Several first fixing holes 110 are provided on the edge of the bottom shell body 100. The edge guard strip body 200 includes an edge guard portion 210 and a fixing portion 220. The fixing portion 220 is located at the bottom end of the edge guard portion 210 and is perpendicular to the edge guard portion 210. The fixing portion faces the inner side of the edge guard portion 210. Several second fixing holes 230 corresponding to the first fixing holes 110 are provided on the fixing portion 220.

[0022] Specifically, in this embodiment, several first fixing holes 110 are provided on the four sides of the bottom shell body 100, and several second fixing holes 230 are provided on the fixing part 220 of the edge strip body 200. During assembly, the edge strip body 200 is placed at the edge of the bottom shell body 100, and the second fixing holes 230 of the fixing part 220 are aligned with the first fixing holes 110. Then, self-tapping screws are threaded through the second fixing holes 230 and connected to the first fixing holes 110, thereby achieving the connection and fixation between the edge strip body 200 and the bottom shell body 100. The use of screw fixing method can ensure the firmness of the connection between the edge strip body 200 and the bottom shell body 100. In addition, to facilitate the screw passing through the second fixing hole 230, the diameter of the second fixing hole 230 is either the same as the diameter of the first fixing hole 110, or the diameter of the second fixing hole 230 is larger than the diameter of the first fixing hole 110. Using the first fixing hole 110 and the second fixing hole 230 with the same diameter facilitates screw insertion and fastening. When the diameter of the second fixing hole 230 is larger than the diameter of the first fixing hole 110, the screw head size will be larger than the diameter of the second fixing hole 230. Therefore, the edge strip body 200 and the bottom shell body 100 can be fastened in the same way. Alternatively, a washer can be placed between the screw head and the second fixing hole 230. The fastening between the edge strip body 200 and the bottom shell body 100 can also be achieved using the washer. The specific choice can be made according to actual needs.

[0023] Please see Figures 1 to 4 To facilitate the assembly and locking of the bottom shell body 100 and the edge strip body 200, this utility model also provides an assembly positioning fixture, which includes a fixture base plate 300, a fixture cover plate 400, a first positioning plate 500, a second positioning plate 600, a movable positioning plate 700, and the module bottom shell and edge strip structure described in any one of the above. The first positioning plate 500 is respectively provided on the left and right sides of the fixture base plate 300, the second positioning plate 600 is provided at one end of the fixture base plate 300, and the movable positioning plate 700 is movably provided at the other end of the fixture base plate 300. The first positioning plate 500, the second positioning plate 600 and the movable positioning plate 700 on both sides together form a positioning assembly groove, and the fixture cover plate 400 covers the positioning assembly groove.

[0024] By setting first positioning plates 500 on the left and right sides of the jig base plate 300, and setting second positioning plates 600 and movable positioning plates 700 on the upper and lower ends of the jig base plate 300, a positioning assembly groove is formed. The size of the positioning assembly groove can be adjusted by the movable positioning plate 700, so that the positioning assembly groove can cooperate with the bottom shell body 100 and the side strip body 200 of different sizes to realize the loading and positioning of the bottom shell body 100 and the side strip body 200.

[0025] Furthermore, a plurality of positioning holes 410 corresponding to the first fixing hole 110 and the second fixing hole 230 are provided on the edge of the fixture cover plate 400, and the diameter of the positioning hole 410 is larger than the diameter of the second fixing hole 230, and an opening is formed on the outside of the positioning hole 410. At the same time, the size of the fixture cover plate 400 is adapted to the inner size of the side guard 210, and a handle 420 is provided in the middle of the fixture cover plate 400.

[0026] When assembling and locking the bottom shell body 100 and the edge strip body 200, the bottom shell body 100 is placed in the positioning assembly groove, and then the edge strip body 200 is placed on the bottom shell body 100. The positioning assembly groove positions the bottom shell body 100 and the edge strip body 200, preventing them from shifting during assembly and ensuring proper positioning between them. After the edge strip body 200 is placed on the bottom shell body 100, the edge strip body 200... The side of edge 210 is flush with the side of bottom shell body 100, and the fixing part 220 is placed on the top edge of bottom shell body 100. The position of the second fixing hole 230 corresponds to the position of the first fixing hole 110. Then, the jig cover plate 400 is covered, and after the jig cover plate 400 is covered, it will be placed inside the side of the retaining edge 210, and its edge will limit the inside of the side of the retaining edge 210. The position of the positioning hole 410 will correspond to the second fixing hole 230 and the first fixing hole 110. At this time, Next, the assembly positioning fixture is placed onto the automatic screw fastening machine, which passes the screws through the positioning hole 410, through the second fixing hole 230, and threadedly connects them to the first fixing hole 110. This achieves the assembly and locking of the edge strip body 200 and the bottom shell body 100. The first positioning plate 500, the second positioning plate 600, and the movable positioning plate 700 limit the outer side of the edge portion 210 of the edge strip body 200, and the fixture cover plate 400 further restricts the edge of the edge strip body 200. The inner side of the edge 210 is limited to prevent deformation and deviation when the edge strip body 200 is locked, thereby improving the assembly quality and efficiency between the edge strip body 200 and the bottom shell body 100. Furthermore, the positioning hole 410, which has a diameter larger than the second fixing hole 230, can prevent the screws from locking the fixture cover plate 400, and the fixture cover plate 400 can be easily removed through the large-diameter positioning hole 410 with an opening, so as to facilitate the removal of the locked bottom shell body 100 and edge strip body 200.

[0027] To facilitate the movement of the movable positioning plate 700, an elongated fixing hole (not shown in the figure) is provided on the fixture base plate 300. The movable positioning plate 700 is movably connected to the fixture base plate 300 through the elongated fixing hole. The movable positioning plate 700 is moved and fixed by screws and nuts engaging with the elongated fixing hole. For example, a groove is provided at the bottom of the elongated fixing hole, the nut is placed in the groove, and the screw is inserted downwards from the top of the movable positioning plate 700, passing through the elongated fixing hole and threadedly connected to the nut. This elongated fixing hole is existing technology and will not be described in detail here.

[0028] Furthermore, to improve the assembly efficiency between the edge strip body 200 and the bottom shell body 100, multiple sets of movable positioning plates 700 are provided in this embodiment. These multiple sets of movable positioning plates 700 are arranged in parallel intervals, and each set cooperates with the first positioning plate 500 and the second positioning plate 600 on both sides to form multiple positioning assembly slots. Through the multiple positioning assembly slots formed by the multiple sets of movable positioning plates 700, multiple edge strip bodies 200 and multiple bottom shell bodies 100 can be assembled and locked simultaneously, thereby improving the assembly efficiency between the edge strip body 200 and the bottom shell body 100.

[0029] In order to facilitate the removal of materials from the assembled base plate body 100 and the edge strip body 200, the first positioning plate 500 is provided with a notch 510, and the position of the notch 510 corresponds to the position of the positioning assembly groove. The notch 510 allows for easy material removal by a robot or by manual labor.

[0030] Finally, to facilitate the handling of the assembly positioning fixture, the fixture base plate 300, first positioning plate 500, second positioning plate 600, movable positioning plate 700, and fixture cover plate 400 are all made of aluminum, and the fixture base plate 300 has weight-reducing holes 310. Because aluminum has a lower density, about one-third that of steel, it is lighter. Combined with the weight-reducing holes 310, this effectively reduces the overall weight of the assembly positioning fixture, thus facilitating its handling and transportation and improving its practical performance.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description; however, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model; furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
