Spot welding is a common technical means of connecting the ear straps to the main body of the mask during the processing and production of masks. Commonly used methods include single-point welding, double-point welding, and semi-automatic welding; single-point welding is to manually hold the mask and ear straps and complete the welding at the four points where the ear straps contact the mask.

[0003] The Chinese patent with the authorization publication number CN115782193A discloses an ultrasonic spot welding machine for mask ear straps, which includes a base, a conveyor belt and a mask template. Baffles are installed on the top of both sides of the base, a conveyor belt is installed between the two baffles, a motor is installed at one end of the baffle on one side, and a support table is installed at one end of the baffle on the other side. Support frames are installed at both ends of the top of the support table, and ultrasonic transmitters are installed on the top of the two support frames. Multiple mask templates are evenly installed on the surface of the conveyor belt through fixed blocks. The patent of the present invention installs a mask template, puts the mask and ear straps into the mask template according to the specified position, and then transmits them to the bottom of the ultrasonic generator through the conveyor belt. When welding the mask and ear straps, it can effectively prevent the ear straps from shifting during welding, and does not require support from staff, and also greatly increases the efficiency of mask production.
