[0023] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-2 As shown, the present invention provides an earphone shell mounting device, which includes a platform 1, a lower mold 2, a clamping plate 3, an upper mold 4, a welding machine 5, and an ejector mechanism 7.

[0025] The tabletop 1 is provided with a connecting hole 11. The first fastener 33 connects the clamping plate 3 to the tabletop 1 through the connecting hole 11. There are two clamping plates 3. The lower mold 2 is located between the two clamping plates 3. The bottom of the lower mold 2 is provided with a base 24. The clamping plates 3 press on the base 24 and abut against the wall of the lower mold 2. Compared with directly abutting the clamping plates 3 against the two sides of the lower mold 2, the clamping and positioning structure that clamps the lower mold 2 while pressing the base 24 can more stably position the material and prevent the lower mold 2 from loosening during welding and assembly.

[0026] The clamping plate 3 is detachably fixed by the first fastener 33, making it easy to assemble and disassemble, and suitable for lower molds 2 of different specifications. The clamping plate 3 is provided with a fastening groove 31, and the table surface 1 is arranged with several connecting holes 11. The second fastener 32 passes through the fastening groove 31 and connects to the connecting holes 11. The second fastener 32 further strengthens the positioning strength of the clamping plate 3 for the lower mold 2, preventing the head of the clamping plate 3 from slipping and loosening against the wall of the lower mold 2. Moreover, the connection holes 11 can be selected at different positions according to the different sizes of the lower mold 2, thereby adjusting the installation position of the first fastener 33 and the second fastener 32.

[0027] like Figure 3 As shown, the lower mold 2 has a bottom shell placement groove 21 on its top, and the upper mold 4 is connected to the welding machine 5, as shown. Figure 4 As shown, the bottom of the upper mold 4 is provided with a cover placement groove 41; the bottom shell placement groove 21 is used to place the earphone bottom shell, and the cover placement groove 41 is used for the earphone cover. Since the earphone bottom shell and cover are small in size, it is not convenient for hand operation when putting in and taking out materials. The edge of the bottom shell placement groove 21 is provided with a first arc surface 23, and the edge of the cover placement groove 41 is provided with a second arc surface 42. The bottom shell quickly lies flat in the bottom shell placement groove 21 along the first arc surface 23. When the upper mold 4 is pressed down, the cover is embedded in the cover placement groove 41 along the second arc surface 42 to avoid the cover shifting during the pressing process.

[0028] The top-loading mechanism 7 is located below the table 1, such as... Figure 5 As shown, the top material mechanism 7 includes a driving component 71, a connecting plate 72, a top rod 73, and a spring 74. The driving component 71 is connected to the top rod 73 through the connecting plate 72, and the spring 74 is connected between the table 1 and the connecting plate 72. The table 1 is provided with a through opening 12, and the bottom surface of the bottom shell placement groove 21 is provided with a top material groove 22. The top rod 73, the top material groove 22, and the through opening 12 are coaxially arranged.

[0029] The driving component 71 can be a cylinder, which drives the push rod 73 to rise and fall. The push rod 73 passes through the material ejection groove 22 and pushes the welded earphone shell out of the bottom shell placement groove 21, facilitating quick unloading by the operator. The spring 74 can act as a buffer to improve the stability of the material ejection.

[0030] A guide rod 75 is provided between the connecting plate 72 and the table surface 1. The guide rod 75 ensures that the top rod 73 always moves up and down along the same straight line, preventing the top rod 73 from deviating.

[0031] like Figure 6 As shown, the top of the ejector rod 73 is provided with an ejector plate 73, which can more stably support the headphone shell and prevent the headphone shell from jumping out of the lower mold 2.

[0032] This utility model discloses an earphone shell mounting device. The bottom shell of the earphone is placed in the bottom shell placement groove 21, and the cover is placed on the bottom shell. The welding machine 5 is an existing ultrasonic plastic welding machine. The upper mold 4 is pressed down, and high-frequency mechanical vibration is used to make the contact surface of the bottom shell and the cover rub and heat up and fuse together, thereby achieving the purpose of assembly. After the upper mold 4 rises and resets, the push rod 73 pushes the assembled earphone shell out from the lower mold 2, which is convenient for the operator to manually unload the material.

[0033] The worktable 1 is equipped with an adjustment mechanism 6, and the welding machine 5 is connected to the worktable 1 through the adjustment mechanism 6. The adjustment mechanism 6 can be an existing worm gear mechanism, thereby realizing the initial height adjustment of the upper mold 4 to adapt to the assembly of headphone shells of different specifications and materials.

[0034] The preferred embodiments of this utility model have been described in detail above, but this utility model is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this utility model, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
