Description

Technical Field

[0001] This utility model relates to the field of assembly tooling technology, and more specifically, to a display cover connecting device. Background Technology

[0002] Currently, most display covers on the market use a snap-fit ​​method between the panel and the housing, which can lead to light leakage due to the gap between the positioning slot and the positioning pin during use, resulting in unclear display.

[0003] In view of this, the applicant hereby submits this application after studying the existing technology. Utility Model Content

[0004] This invention provides a display cover connecting device, which aims to improve at least one of the above-mentioned technical problems.

[0005] To solve the above-mentioned technical problems, this utility model provides a display cover connecting device, including a base and a top block. The upper end of the base is provided with a placement groove suitable for placing a panel. The lower end of the top block is connected to a heating module. A housing is provided between the panel and the heating module. Multiple connecting grooves are provided through the housing. A connecting block that matches the connecting groove is formed on the panel. The connecting block extends through the connecting groove into the housing. The bottom end of the heating module is provided with multiple welding parts corresponding to the positions of the connecting grooves. The ends of the welding parts are recessed to form welding grooves. Each welding groove matches the connecting block below it.

[0006] As a further optimization, a groove is coaxially provided at the end of the connecting groove away from the panel.

[0007] As a further optimization, the end cross-section of the welded portion is smaller than the cross-section of the groove.

[0008] As a further optimization, the welding part protrudes axially from the bottom end of the heating module and is arranged in a cylindrical shape.

[0009] As a further optimization, a limit stop is provided at the bottom of the heating module.

[0010] As a further optimization, a slot is provided on one side of the base to connect with the placement groove.

[0011] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0012] This application provides a display cover connecting device, including a base and a top block. The upper end of the base has a placement groove for positioning a panel. A heating module is connected to the lower end of the top block. The bottom end of the heating module has multiple welding portions corresponding to the positions of the connecting grooves on the housing. The ends of the welding portions are recessed to form welding grooves, each welding groove matching a connecting block on the lower panel that passes through the connecting groove. By controlling the heating module to descend, the welding groove covers the connecting block. The interior of the welding groove acts as a heating unit, heating the connecting block upon contact, thereby thermally fusing the connecting block and the connecting groove together and forming a seal. This prevents light leakage at the connection point, resulting in a clearer display on the panel. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Depend on Figures 1 to 6 As shown, this utility model embodiment provides a display cover connecting device, including a base 1 and a top block 2. The display cover includes a panel 3 and a housing 4. The panel 3 is used to connect to the outer side of the housing 4, and the inner side of the housing 4 is used to place light-emitting devices. Preferably, the upper end of the base 1 is provided with a placement groove 5 suitable for placing the panel 3 for positioning the panel 3, with the connecting surface of the panel 3 facing upward. A heating module 6 is connected to the lower end of the top block 2, and the movement of the heating module 6 is controlled by controlling the up and down movement of the top block 2 through a driving mechanism (not shown in the figure). During operation, the housing 4 is placed on the panel 3 and between the heating module 6. The housing 4 has multiple connecting grooves 7 running through it, and the panel 3 has protruding connecting blocks 8 that match the connecting grooves 7. The connecting blocks 8 extend through the connecting grooves 7 into the housing 4. The bottom end of the heating module 6 is provided with multiple welding portions 9 corresponding to the positions of the connecting grooves 7. The ends of the welding portions 9 are recessed to form welding grooves 10, and each welding groove 10 matches the connecting block 8 below it. During operation, panel 3 is placed on placement slot 5, and housing 4 is positioned on top of panel 3 via connecting slot 7 and connecting block 8. Top block 2 descends, causing welding groove 10 to cover connecting block 8. The interior of welding groove 10 acts as a heating unit, heating the connecting block 8 upon contact, thereby thermally fusing the connecting block 8 with connecting slot 7. Figure 6 This is to prevent light from escaping through the connection nodes, making the display on panel 3 clearer.

[0023] The axial positioning between the base 1 and the top block 2 can be achieved by matching the fixed base 1 with the drive mechanism above, or by setting guide posts. There are multiple methods, which will not be elaborated here.

[0024] Preferably, a groove 11 is coaxially provided at the end of the connecting groove 7 away from the panel 3. By providing a groove 11 at the connecting groove 7, and at the same time, the end cross-sectional size of the welding part 9 is smaller than the cross-sectional size of the groove 11, the welding part 9 can gradually extend into the groove 11 during the melting process, and the connecting block 8 can be concentrated and covered in the groove 11 after melting. This can not only concentrate and restrict the molten material, but also enhance the connection and sealing effect.

[0025] Preferably, the welding portion 9 protrudes axially from the bottom end of the heating module 6 and is cylindrical in shape. By providing a certain axial length to the welding portion 9, it is possible for the welding portion 9 to extend into the housing 4 and mate with the connecting groove 7, without being affected by other protruding structures of the housing 4.

[0026] Preferably, a limiting block 12 is provided at the bottom of the heating module 6. The limiting block 12 is a heat insulation component. During welding, the limiting block 12 is positioned between the housing 4 and the heating module 6. It not only applies pressure to the housing 4, tightly abutting it against the panel 3 for connection, but also serves as a limiting element, preventing the welding part 9 from excessively melting the housing 4 and damaging it. In this embodiment, two limiting blocks 12 are provided to ensure balanced abutment.

[0027] Preferably, a slot 13 is provided on one side of the base 1, which connects to the placement groove 5 and extends to the bottom of the panel 3. In order to better position the panel 3, the panel 3 is embedded in the placement groove 5 during connection. Therefore, by providing a slot 13 on one side of the placement groove 5, the panel 3 can be easily removed after the heat fusion connection is completed.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
