Description

Technical Field

[0001] This utility model relates to the technical field of cabinet assembly devices, and in particular to a variable-size speaker assembly device. Background Technology

[0002] The speaker is the core component of an audio system, responsible for converting electrical signals into sound waves that humans can hear. It is the terminal device for sound output and directly affects sound quality.

[0003] During the assembly of wooden speaker enclosures, after applying glue to the seams, the various components of the enclosure must be assembled according to the process and then secured with PP straps. The straps are only removed after the glue has dried to prevent the enclosure from warping or even falling apart if the glue is not completely dry. This process requires an automatic packing machine and disposable PP straps, which cannot be reused. Simply strapping the speaker enclosure with PP straps to secure it and then removing them afterward is not only time-consuming and wasteful of materials, but also environmentally unfriendly, contradicting the societal principles of energy conservation, emission reduction, and environmental protection.

Detailed Implementation

[0025] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0026] This embodiment provides a variable-size speaker assembly device, such as... Figure 1 As shown, it includes a support frame 1, a cylinder frame 2 fixedly installed at the top inside the support frame 1 in an inclined shape, and a cylinder 3 installed on the cylinder frame 2. The piston rod of the cylinder 3 is inclined downward, preferably at 45° in this embodiment. The piston rod pushes the extrusion frame 7 to press each panel of the speaker 6 forward and downward. The chamfered panels of the speaker 6 interlock with each other to prevent misalignment and maintain the original shape of the speaker 6. It also includes: the speaker 6, the junction of each panel of the speaker 6 shell is processed into a chamfered shape so that each panel interlocks with each other when under pressure;

[0027] Side support part 4 is provided on one side of the support frame 1 and is used to provide a counter thrust to the side wall of the speaker 6. The side support part 4 can adjust the horizontal position of the speaker 6.

[0028] The bottom support part 5 is horizontally disposed inside the support frame 1 and is used to support the speaker 6. The bottom support part 5 can adjust the vertical position of the speaker 6.

[0029] like Figure 2 and 3 As shown, a compression frame 7 is fixedly provided at the bottom of the piston rod of cylinder 3.

[0030] The extrusion frame 7 is a strip with an L-shaped cross-section. The opening of the extrusion frame 7 faces the top edge of the speaker 6. When the cylinder 3 pushes the extrusion frame 7 to squeeze the top edge of the speaker 6, the top edge of the speaker 6 is exactly located inside the extrusion frame 7, and the two fit together completely, increasing the contact area between the extrusion frame 7 and the speaker 6 and preventing the speaker 6 from being squeezed and deformed.

[0031] The side support part 4 includes a side support plate 41, which is fixedly mounted vertically on the side of the support frame 1 and faces the cylinder 3.

[0032] The side support part 4 also includes a side support plate 42, which is arranged in parallel with the side support plate 41, and the side support plate 42 is located inside the side support plate 41.

[0033] Both the side support plate 42 and the side brace plate 41 are provided with a lateral lead screw 43 and a lateral guide rod 44. The lateral lead screw 43 passes through the side support plate 42 and is rotatably connected to the side brace plate 41. The lateral guide rod 44 passes through the side support plate 42 and is rotatably connected to the side brace plate 41. The outer ring of the lateral lead screw 43 is fitted with a lateral lead screw nut 45. The lateral lead screw nut 45 is threadedly connected to the lateral lead screw 43 and is rotatably connected to the side brace plate 41.

[0034] The lateral lead screw 43 can slide back and forth along the side support plate 42 and can rotate freely. The lateral guide rod 44 can slide back and forth along the side support plate 42. Rotating the lateral lead screw nut 45 drives the lateral lead screw 43 to move left and right, thereby pushing the side support plate 41 to move left and right, so that the compression frame 7 can compress the speaker 6 to adapt to speaker 6 of different widths.

[0035] The bottom support part 5 includes a bottom support plate 52, which is fixedly installed in the support frame 1 in the horizontal direction.

[0036] The bottom support part 5 also includes a bottom support plate 51, which is arranged parallel to the bottom support plate 52 and is located above the bottom support plate 52.

[0037] Both the bottom support plate 51 and the bottom support plate 52 are equipped with bottom lead screws 53 and several bottom guide rods 54.

[0038] The bottom lead screw 53 passes through the bottom support plate 52 and is rotatably connected to the bottom support plate 51. The bottom guide rods 54 all pass through the bottom support plate 52 and are rotatably connected to the bottom support plate 51. The bottom lead screw nut 55 is sleeved on the outer ring of the bottom lead screw 53. The bottom lead screw nut 55 is threadedly connected to the bottom lead screw 53 and is rotatably connected to the bottom support plate 52.

[0039] The bottom lead screw 53 can slide back and forth along the bottom support plate 52 and can rotate freely. The bottom guide rods 54 can also slide back and forth along the bottom support plate 52. Rotating the bottom lead screw nut 55 drives the bottom lead screw 53 to move up and down, thereby pushing the bottom support plate 51 to rise and fall, so that the compression frame 7 can compress the speaker 6 to adapt to speakers 6 of different heights.

[0040] like Figure 4 As shown, a solenoid valve and a time relay for controlling the solenoid valve are installed inside the cylinder 3. The action time of the time relay is set to the length of time it takes for the hot melt adhesive to completely cure. Once the time is up, the time relay controls the solenoid valve to open the cylinder and complete the pressing action.

[0041] Apply a layer of glue to the chamfered edges of the top, bottom, and left and right side panels of speaker 6 to form a cuboid for initial fixation. Place speaker 6 on the base support plate 51 and rotate the lateral screw nut 45 and bottom screw nut 55 to adjust the positions of the side support plate 41 and the base support plate 51, thereby changing the position of speaker 6 so that when cylinder 3 pushes the pressing frame 7 forward, the pressing frame 7 presses precisely on the top edge of speaker 6. Quickly apply a layer of hot melt glue to the outside of the junction of the top, bottom, and left and right side panels of speaker 6. Activate cylinder 3, which pushes the pressing frame 7 toward speaker 6. Before the hot melt glue solidifies, the pressing frame 7 presses the top edge of speaker 6, making the top, bottom, and left and right side panels of speaker 6 tightly adhere together. After the hot melt glue solidifies, retract the piston rod of cylinder 3, and the pressing frame 7 leaves speaker 6, thus adhering the top, bottom, and left and right side panels of speaker 6 together.

[0042] Fix the front and rear side panels of speaker 6 in the above manner to complete the assembly of speaker 6.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
