[0002] A welding mask is a protective device used by welders to effectively protect themselves during welding, effectively shielding the eyes and face from arc radiation. However, while this effective protection comes with some inconveniences, such as viewing welding machine parameters.

The optical waveguide assembly is integrally bonded and fixed to the welding mask body. The bonding standard is that the coupling display window of the optical waveguide lens is located within the liquid crystal glass area, and the fixed cover is located outside the liquid crystal glass area.

[0016] The device comprises a wire which connects an operation control circuit PCB board, an optical waveguide component, a power supply of a welding mask body and a welding control circuit; and transmits a signal received by the operation control circuit PCB board to the optical waveguide component for amplified display via the wire.

[0025] Bulleted List DETAILED DESCRIPTION

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] As shown in Figures 1-7, a welding mask with an optical waveguide assembly for an IoT-based welding system includes a wireless signal receiver 1, an optical waveguide assembly 2, a welding mask body 4, a mounting housing 5, wires 7, and screws 9. The welding mask body 4 has a mounting hole for the wireless signal receiver and two mounting holes for the mounting housing. The welding mask body 4 also features a color-changing function for mask protection.

[0028] Figure 4 shows the wireless signal receiver and the calculation and control circuit PCB, which has two mounting holes. The calculation and control circuit PCB 14 is fixedly mounted within the fixed housing 5. The wireless signal receiver 1 is mounted within the fixed housing 5 and is signal-connected to the calculation and control circuit PCB 14, transmitting received signals to the calculation and control circuit PCB. The top end of the wireless signal receiver 1 extends through the wireless signal receiver mounting hole in the welding mask body 4 and is exposed to the outside of the welding mask body 4.

[0029] As shown in Figures 2 and 3, the fixed shell 5 is a plastic box-shaped structure with an open upper end. Two fixed shell mounting studs 6 are provided in the fixed shell 5. The two fixed shell mounting studs 6 pass through the two mounting holes on the PCB board and correspond one-to-one with the two fixed shell mounting holes on the welding mask body 4. The fixed shell 5 is fixedly connected by screws 9 to install it inside the welding mask body 4.

[0030] The optical waveguide assembly shown in Figure 6 includes a microdisplay 13, a fixed cover 12, and an optical waveguide lens 11. The microdisplay 13 is fixed to one end of the optical waveguide lens 11 via the fixed cover 12 to form an integral unit. The information displayed on the microdisplay 13 is magnified and displayed through the optical waveguide lens 11 in a coupled display window 16 at the other end of the optical waveguide lens 11. The optical waveguide assembly 2 is fixed to the welding mask body 4 by gluing. The glue can be applied to the liquid crystal glass of the welding mask using transparent glue or to the side of the liquid crystal glass. The bonding standard is that the coupled display window 16 of the optical waveguide lens 11 is located within the liquid crystal glass area, and the fixed cover 12 is located outside the liquid crystal glass area. This is because the fixed cover 12 must not enter the liquid crystal glass area of ​​the welding mask to avoid affecting the welder's vision.

[0031] The wires on the calculation and control circuit PCB pass through the U-shaped notch 15 of the fixed shell. They connect the optical waveguide assembly 2, the power supply of the welding mask body, and the welding control circuit 8. The signals received by the calculation and control circuit PCB are transmitted to the optical waveguide assembly through wires 7 for amplification and display.

[0032] Figure 7 illustrates the working principle of an optical waveguide assembly: A microdisplay 13 displays various signals, such as voltage, current, and alarm signals. These signals, such as light 19, enter the assembly through an incoupling window 17. The light propagates within the assembly, where its coating 18 propagates the light in a specific pattern until it exits through an outcoupling display window 16 and reaches the human eye. The entire assembly is transparent, offering excellent light transmittance, ensuring unobstructed viewing of objects within the area covered by the assembly.

[0033] During installation, as shown in Figure 5, install the wireless signal receiver inside the welding mask body. Drill a hole for the wireless signal receiver in the top of the welding mask body (or other suitable location). The hole diameter can be determined by the exposed portion of the wireless signal receiver. Next, drill two mounting holes for the mounting housing. The sizes of the two mounting holes are determined by the two screws in the mounting housing. Then, place the wireless signal receiver and the operation and control circuit PCB into the mounting housing and insert the wires into the U-shaped notch of the mounting housing. Attach the mounting housing to the welding mask with screws.

[0034] The wireless signal receiver receives wireless signals from the paired welding equipment (including but not limited to welding current, voltage, shielding gas pressure, wire feed speed, and alarm signals). These signals are then transmitted to the calculation and control circuit PCB, which then transmits these signals via wires to the optical waveguide assembly, which amplifies and displays the corresponding welding parameters or alarm information. The optical waveguide assembly has excellent light transmittance, ensuring that the normal viewing and protective functions of the welding mask remain intact. This allows the welding mask to provide intuitive display of relevant parameters while protecting the welder, making welding more convenient.

[0035] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
