Description

Technical Field

[0001] The utility model belongs to the technical field of welding protection equipment, in particular to a welding mask with a wireless remote control light-changing lens that changes from a transparent lens to a dark lens. Background Art

[0002] On July 27, 2022, the applicant submitted a Chinese utility model patent with publication number CN218684932U, "A Wireless Remote Control Flip Welding Mask". In actual application, it solved the problem of frequently having to manually lift and close the welding mask, thereby improving welding efficiency. However, this solution also has some defects. For example, when the sunglasses are flipped by remote control, if the flipping speed is designed to be too slow, it will affect the welding efficiency. If the flipping speed is designed to be too fast, the flipped sunglasses frame will impact and collide with the welding mask, making a "bang bang" sound. Long-term use will cause auditory fatigue to the welder.

[0003] Existing auto-darkening welding masks have achieved a delay of only 0.1 milliseconds for changing the color of the lens from clear to dark. If this auto-darkening welding mask is used for a short period of time, the welder's eyes will not feel the damage caused by the strong welding light. However, if this welding mask is used for a long time, the welder's eyes will be exposed to the strong welding light for a long time, which will affect the welder's vision and cause the occupational disease of electro-optical eye.

[0004] Numerous prior art solutions exist for welding protective masks, including CN217448215U, a light-changing welding mask for a multifunctional argon arc cold welder; CN207627484U, an automatic light-changing welding mask; CN211326113U, a wireless infrared remote-controlled automatic light-changing welding mask; and CN204192860U, a novel welding goggles and their wireless controller. These solutions fall into two categories: automatic light-changing and manual light-changing. Automatic light-changing solutions often lack adjustable light-changing delays or require complex setup, consuming time and effort. Manual light-changing solutions typically require a control switch mounted on the welding mask. This requires holding the welding torch in one hand and controlling the welded part in the other, forcing the user to pre-activate the light-changing lens switch, free up one hand to touch the switch, or hold the workpiece or welding torch to touch the switch, making operation very inconvenient. Summary of the Invention

[0005] In response to the problems described in the background technology, the present invention aims to provide a wireless remote-controlled dimming lens welding protective mask, which can not only accurately control the start and close time of the dimming lens to protect the welder's eyes, but also facilitate the actual operation of the welder.

[0006] In order to solve the problems described in the background technology, the present invention adopts the following technical solutions:

[0007] Wireless remote control dimming lens welding protective helmet, including:

[0008] A visor helmet, wherein the visor helmet is provided with an observation window;

[0009] A variable light lens installed in the observation window;

[0010] A wireless remote control receiver, which is fixed to the mask helmet and connected to the power supply of the electrode that controls the arrangement direction of the liquid crystal in the variable light lens, and is used to output a switching signal to the power supply of the electrode;

[0011] A wireless remote control controller is configured in any of the following three ways:

[0012] The wireless remote control controller is installed on the welding gun, and the wireless remote control controller is connected to the wireless remote control key switch, and the wireless remote control key switch is installed near the switch of the welding gun;

[0013] Alternatively, the wireless remote control controller is installed on the welding gun, and the wireless remote control controller and the welding gun share a switch;

[0014] Alternatively, the wireless remote control controller is connected to a wireless remote control foot switch.

[0015] Regarding remote control method 1: Fix the wireless remote controller on the welding gun and fix the wireless remote control button switch behind the welding gun switch. Before welding, the welder first presses the "off" button of the wireless remote control button switch to send a shutdown signal. After the wireless remote control receiver receives the shutdown signal, it controls the dimmer lens to change from a transparent lens to a dark lens. Then, press the "on" button of the welding gun switch to start the welding arc and start welding. After the weld is completed, press the "off" button of the welding gun switch to turn off the welding arc and stop welding. No more welding strong light is emitted. Then press the "on" button of the wireless remote control button switch to send a start signal. After receiving the start signal, the wireless remote control receiver controls the dimmer lens to change from a dark lens to a transparent lens.

[0016] Regarding the second remote control method: the remote control button switch and the welding switch of the welding gun are designed to be a master switch. The master switch is fixed on the welding gun. When the master switch is pressed for the first time, the dimmer lens is controlled to change from a transparent lens to a dark lens. After a delay of 0.01 seconds, the welding gun is controlled to start the arc and start welding. After the weld is completed, the master switch is pressed for the second time. The welding arc is turned off first, the welding light disappears, and after a delay of 0.01 seconds, the dimmer lens is controlled to change from a dark lens to a transparent lens.

[0017] Regarding the third remote control method: the switch of the wireless remote controller is designed as a foot switch. Before welding, step on the wireless remote control foot switch for the first time to control the diopter lens from transparent lens to dark lens, and then press the "on" button of the welding gun to start the welding arc and start welding. After the weld is completed, press the "off" button of the welding gun to turn off the welding arc and stop welding. No more welding strong light is emitted, and then step on the wireless remote control foot switch for the second time to control the diopter lens from dark lens to transparent lens.

[0018] Compared with the existing technology, the utility model overcomes the defects of remote-controlled sunshade sunglasses with mechanical flip-up welding protective masks, which have a flipping delay affecting work efficiency and noise, and the defect of automatic darkening welding protective masks, which have a dimming delay causing eyes to be irradiated with strong light.

[0019] Compared to the drawback of light-sensitive automatic-darkening welding helmets, which require strong welding light to trigger the light-sensitive switch and change the dimming lens from clear to dark lens, this process requires strong light to be emitted before the dimming lens changes from clear to dark lens, resulting in a light-sensing delay. During this delay, the eyes are directly exposed to the strong welding light radiation, causing eye damage. Although the light-sensing delay is only 0.1 milliseconds, long-term use can lead to the occupational disease of electro-optical eye. The remote-controlled dimming lens welding helmet adopted by the utility model solves the problem of light-sensing delay. The dimming lens is first remotely controlled to change from clear to dark lens before welding. Before the strong welding light is emitted, the dimming lens has already changed from clear to dark lens, eliminating the strong light exposure to the eyes and protecting the eyes throughout the welding process. In contrast, light-sensitive automatic-darkening welding helmets cannot protect the eyes from the strong welding light radiation during this delay. The remote-controlled dimming welding helmet technology solves this drawback and protects the welder's eyes from the strong welding light radiation throughout the welding process.

[0020] Compared with the solution of mechanically flipping sunglasses, the utility model does not make additional noise when the dimming lenses are triggered, and will not affect welders.

[0021] Compared with the solution of setting the dimming lens switch on the mask, the utility model integrates the dimming lens switch into the welding gun, or replaces it with a foot switch, so there is no need to free up an extra hand to trigger the dimming lens, which makes operation easier.

[0027] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. However, it should not be understood that the scope of the subject matter described in the present invention is limited to the following embodiments. Without departing from the above-mentioned technical ideas of the present invention, various modifications, substitutions and changes made according to common technical knowledge and customary means in the field are included in the scope of the present invention.

[0028] The utility model designs a welding mask with a wireless remote control transparent lens that can be changed into a dark lens. The structure of the welding mask comprises a mask helmet 1, a variable light lens 2, a wireless remote control receiver 3 and a wireless remote control controller 4.

[0029] The variable light lens 2 and the wireless remote control receiver 3 are installed on the mask helmet 1. The switch control design of the wireless remote control controller 4 has three control modes:

[0030] Remote control switch control method 1, such as Figure 2 , install the switch of the wireless remote controller 4 (wireless remote control button switch 5) on the welding gun 8. Before the welder welds, the dimming lens 2 is in the transparent lens state, and the welder can clearly observe the weld. When the welder welds, he first presses the "off" button of the wireless remote control button switch 5, and the dimming lens 2 changes from a transparent lens to a dark lens. Then the welder presses the "on" button of the welding gun 8 to start welding. At this time, the dark lens blocks the strong welding light to protect the eyes. After welding is completed, the welder presses the "off" button of the welding gun 8 to end welding. The weld will no longer emit strong welding light. At this time, the welder presses the "on" button of the wireless remote control button switch 5, and the dimming lens 2 changes from a dark lens to a transparent lens, and the welder can clearly observe the weld.

[0031] Remote control switch control method 2, such as Figure 3The switch button of the wireless remote controller 4 and the welding switch button of the welding gun 8 are integrated into one switch button. That is, there were originally four switch buttons, but now the four switch buttons are integrated into one wireless remote controller and welding main switch 7. Before the welder welds, the dimmer lens 2 is in the transparent lens state, and the welder can clearly observe the weld. When the welder welds, the first time he presses the wireless remote controller and welding main switch 7, the dimmer lens 2 changes from transparent to dark lens. 0.01 second later, the welding starts to emit strong light. At this time, the dimmer lens 2 has already changed from transparent to dark lens before the strong light is emitted, protecting the welder's eyes from the harm of strong light exposure. After welding is completed, the welder presses the wireless remote controller and welding main switch 7 a second time, and the welding ends and no strong light is emitted. 0.01 second later, the dimmer lens 2 changes from dark lens to transparent lens, and the welder can clearly observe the weld.

[0032] Remote control switch control method three, such as Figure 4 , the switch of the wireless remote control controller 4 is installed on a wireless remote control foot switch 6. When the wireless remote control foot switch 6 is stepped on for the first time, the remote control dimming lens 2 changes from a transparent lens to a dark lens. When the wireless remote control foot switch 6 is stepped on for the second time, the remote control dimming lens 2 changes from a dark lens to a transparent lens. Before welding, the welder first steps on the second time 6, and the remote control dimming lens 2 changes from a transparent lens to a dark lens. Then, the welder presses the welding "on" button of the welding gun 8 to start welding. At this time, the dark lens can block the strong light emitted by welding and protect the eyes. After welding is completed, the welder first presses the welding "off" button of the welding gun 8 to end welding. After welding is completed, the welding strong light is no longer emitted. Then, the wireless remote control foot switch 6 is stepped on again, and the remote control dimming lens 2 changes from a dark lens to a transparent lens. The welder can clearly observe the weld.

[0033] like Figure 1 The dimmer lens 2 is mounted on the mask helmet 1, and the wireless remote control receiver 3 is mounted on the mask helmet 1. The wireless remote control receiver 3 is electrically connected to the dimmer lens 2 through a wire. The wireless remote control receiver 3 controls the dimmer lens to switch between the transparent lens mode and the sunglasses lens mode by receiving the switch information sent by the wireless remote control controller 4.

[0034] On the one hand, because all three remote control methods remotely control the dimming lens 2 to change from a transparent lens to a dark lens before the welding glare is generated, the welder's eyes are protected from the welding glare. On the other hand, all three remote control methods remotely control the dimming lens 2 to change from a dark lens to a transparent lens after the welding glare disappears. This design protects the welder's eyes from being damaged by the welding glare throughout the entire welding process.

[0035] The above is only one specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
