Specifically, the ear strap assembly 33 includes an ear strap linear drive module 331 and an ear strap clamp 332. The ear strap linear drive module 331 is mounted on the frame 1 and connected to the ear strap clamp 332. The ear strap linear drive module 331 drives the ear strap clamp 332 to move closer to the ear strap guide module 32, causing the ear strap clamp 332 to clamp the ear strap on the ear strap guide module 32. The ear strap linear drive module 331 drives the ear strap clamp 332 to move away from the ear strap guide module 32, causing the ear strap clamp 332 to pull the ear strap out of the ear strap guide module 32.

After the ear strap is cut by the cutting assembly 34, the ear strap linear drive module 411 drives the two ear strap carrying clamps 42 to move in the opposite direction, so that the two ear strap carrying clamps 42 carry the ear strap to the welding station 13. Then, the two ear strap flipping cylinders 413 respectively drive the two ear strap carrying clamps 42 to flip, thereby flipping the two ends of the ear strap onto the mask surface located at the welding station 13, so that the ultrasonic welding mechanism 5 can weld the mask surface and the ear strap together. However, the structure of the ear strap clamping moving drive mechanism 41 is not limited to this. For example, the ear strap clamping moving drive mechanism 41 can also adopt an existing three-axis manipulator or a four-axis manipulator, etc.

The specific structure and principle of the welding upper portion 51 and the welding lower portion 52 of the ultrasonic welding mechanism 5 are well known to those skilled in the art and are not described in detail here.

[0033] See also Figure 1 and Figure 9 The head-mounted welding headset 100 of the present invention further includes a blanking robot 6, which is disposed on the frame 1.

The output end of the blanking transverse movement cylinder 63 is connected to the blanking clamp 64. The blanking transverse movement cylinder 63 can drive the blanking clamp 64 to move transversely. The blanking clamp 64 is used to grab the mask surface body with welded ear straps. The unloading clamp 64 is driven downward by the unloading lifting cylinder 61, so that the unloading clamp 64 grabs the mask with the ear straps welded to it at the welding station 13. The unloading lifting cylinder 61 drives the unloading clamp 64 upward, and the unloading transverse cylinder 63 drives the unloading clamp 64 transversely, thereby transporting and unloading the grabbed mask. However, the structure of the unloading robot 6 is not limited to this. For example, the unloading robot 6 can adopt an existing three-axis robot or a six-axis robot.

[0034] Combine Figures 1 to 9 The specific working principle of the headset 100 of the present invention is as follows:

[0035] The loading rotation drive mechanism 231 drives the driving wheel 232 to rotate forward or reverse, thereby driving the synchronous transmission member 235 arranged around the driving wheel 232, the first driven wheel 233 and the second driven wheel 234 to rotate forward or reverse, thereby driving the first clamp assembly 21 and the second clamp assembly 22 to move respectively, so that when the first clamp assembly 21 is located at the first loading station 11, the second clamp assembly 22 is located at the welding station 13, or, when the first clamp assembly 21 is located at the welding station 13, the second clamp assembly 22 is located at the second loading station 12. The first clamp assembly 21 is loaded at the first loading station 11 or the second clamp assembly 22 is loaded at the second loading station 12. At the same time, the ear strap clamping mechanism 4 drives the two ear strap carrying clamps 42 to move through the ear strap clamping linear drive module 411, so that the ear strap carrying clamps 42 first clamp the two ends of the ear strap pulled out by the ear strap pulling assembly 33. After the ear strap is cut by the cutting assembly 34, the ear strap clamping linear drive module 411 drives the two ear strap carrying clamps 42 to move in the opposite direction, so that the two ear strap carrying clamps 42 carry the ear strap to the welding station 13, and then the two ear strap clamping flip cylinders 413 respectively drive the two ear strap carrying clamps 42 to flip, thereby flipping the two ends of the ear strap onto the mask surface body located at the welding station 13. The welding lower portion 52 of the ultrasonic welding mechanism 5 rises and fixes the mask surface body on the second clamp assembly 22 through the second positioning hole 221, and the welding upper portion 51 descends and welds the mask surface body and the ear strap together. Finally, the blanking robot 6 takes the mask surface body with the ear straps welded thereon from the first fixture assembly 21 or the second fixture assembly 22 and blanks it.

[0036] In summary, the head-mounted welding headset 100 of the present invention can weld the mask surface and ear straps while loading the next mask surface to be processed, so that after the previous mask surface and ear straps are welded together, the first clamp assembly 21 and the second clamp assembly 22 are switched to achieve rapid material replacement, thereby improving production efficiency.
