Description

Technical Field

[0001] This invention belongs to the field of welding, and specifically relates to a welding helmet for observing the molten pool. Background Technology

[0002] Welding operations require strict process control according to welding technology requirements. Constant and careful observation of the weld pool is crucial to promptly adjust electrode and wire handling techniques or halt welding in case of abnormalities. Because welding arc light is highly irritating and harmful to the eyes, measures must be taken to reduce arc light damage while ensuring effective observation of the weld pool. In traditional manual welding, welders primarily use welding helmets with goggles for protection. However, goggles cannot completely prevent arc light damage; they only provide some protection by reducing the amount of light entering the weld pool and also affect the welder's real-time observation of the weld pool. This situation makes welding quality control extremely difficult and results in a very short career path for welders. Furthermore, welding operators require high skill levels and have long training / certification periods. As years of experience accumulate, welders often retire from frontline work due to eye injuries or other reasons, even at a high level of skill and experience, causing losses to individuals, companies, and the industry as a whole.

[0003] In recent years, some automatic welding machines have been equipped with cameras and displays to avoid arc damage through digital display. However, this method lacks flexibility and versatility. Therefore, a new welding observation tool is needed. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a welding helmet for observing the molten pool.

[0005] The present invention is implemented as follows: a weld pool observation welding helmet, comprising a multi-link, a helmet optical chip transparent screen, a helmet body, an external battery, a flashlight, and an industrial digital camera;

[0006] One end of the multi-link is fixed to the bottom of the helmet, and the other end is connected to the industrial digital camera; the lighting flashlight is installed below the industrial digital camera; the external battery is installed on the left side of the inner shell of the helmet.

[0007] As described above, in a weld pool observation welding helmet, the industrial digital camera and the optical chip transparent screen are connected by a PD cable, and the external battery material is lithium iron phosphate, which provides the power required for the operation of the weld pool observation welding helmet, and is connected to the industrial digital camera and the optical chip transparent screen respectively through a power cable.

[0008] As described above, a welding helmet for observing a molten pool includes a shell, an observation window, a ventilation opening, and an adjustment ring.

[0009] The welding helmet for observing the molten pool described above has an outer shell made of PP material, which is shockproof, drop-resistant, and lightweight.

[0010] As described above, in a weld pool observation welding helmet, the optical chip transparent screen includes optical components, an adaptive dimming device, an automatic focusing device, and auxiliary software.

[0011] As described above, in a weld pool observation welding helmet, the optical chip transparent screen is mounted on the observation window, and the two ventilation openings are respectively located on both sides of the outer shell.

[0012] The welding helmet for observing molten pools, as described above, has an optical chip transparent screen with a resolution of up to 1280x1024 pixels and a high dynamic performance of ≥140dB.

[0013] The above-mentioned weld pool observation helmet, wherein the industrial digital camera has functions such as high pixel count, high temperature resistance, three-proof (waterproof, dustproof, and shockproof) and storage, and its size is 40x43x90mm.

[0014] As described above, in a weld pool observation welding helmet, the optical chip transparent screen selectively controls light through a nano-optical structure. When no display is needed, it is just an ordinary piece of glass; when a display is needed, it switches to a display screen.

[0015] The significant advantages of this invention are: it has the advantages of reasonable design, strong practicality, safety and reliability, wide versatility, and high flexibility, and is used in a welding helmet that can directly display the image of the weld pool during manual welding. Specifically, it includes the following:

[0016] 1. The wearer of the weld pool observation helmet of the present invention can adjust the position of the industrial digital camera through the multi-link to obtain a better welding observation environment, meet the framing requirements under different conditions, and solve traditional welding problems such as difficult positions and insufficient space.

[0017] 2. The weld pool observation welding helmet of the present invention integrates the optical chip transparent screen on the observation window, which completely isolates the direct arc light during the welding process and can effectively avoid arc light damage during welding operations.

[0018] 3. The weld pool observation helmet of the present invention, because the industrial digital camera can be closer to the weld pool than the human eye, the shortened observation distance can improve the observation effect of the weld pool and is beneficial to welding quality control.

[0019] 4. The weld pool observation welding helmet described in this invention can realize functions such as full-process recording and storage from a first-person perspective, remote monitoring, and visual operation assistance, thereby improving welding quality and engineering traceability.

[0020] 5. The optical chip transparent screen has high pixel density and high dynamic performance (≥140dB), which can clearly observe the electric arc and molten pool, and can switch freely between the display screen and the transparent glass, resulting in high performance and flexibility.

[0021] 6. The external battery is made of lithium iron phosphate material, which has the advantages of high discharge power, fast charging and long cycle life, large capacity per unit weight, and high stability in high temperature and high heat environment. Attached Figure Description

[0028] A welding helmet for observing molten pools includes a multi-link system, a transparent screen with a helmet optical chip, a helmet body, an external battery, a flashlight, and an industrial digital camera.

[0029] One end of the multi-link is fixed to the bottom of the helmet, and the other end is connected to the industrial digital camera. A flashlight is mounted below the industrial digital camera. The external battery is mounted on the left side of the inner shell of the helmet.

[0030] The industrial digital camera and the transparent screen of the optical chip are connected by a PD cable. The external battery material is lithium iron phosphate, which provides the power required for the operation of the weld pool observation helmet. It is connected to the industrial digital camera and the transparent screen of the optical chip through a power cable.

[0031] The helmet body includes an outer shell, observation window, ventilation opening, and adjustment band.

[0032] The outer shell is made of PP material, which is shockproof, drop-resistant, and lightweight.

[0033] The optical chip transparent screen includes optical components, an adaptive dimming device, an autofocus device, and auxiliary software.

[0034] The optical chip transparent screen is mounted on the observation window, and the two ventilation openings are respectively located on both sides of the outer casing.

[0035] Furthermore, the optical chip transparent screen has a resolution of up to 1280x1024 pixels and high dynamic performance (≥140dB).

[0036] The industrial digital camera features high resolution, high temperature resistance, ruggedness, and storage capabilities, and measures (40x43x90) mm in size.

[0037] The optical chip transparent screen can selectively control light through a nano-optical structure. When not in use, it is just a piece of ordinary glass, and when needed, it switches to a display screen.

[0038] The welder wears the welding helmet for observing the weld pool. By actively changing his / her position and posture or manually adjusting the length and shape of the multi-link, the industrial digital camera can be positioned at the optimal location for observing the weld pool.

[0039] The real-time images captured by the industrial digital camera are displayed on the transparent screen of the optical chip in real time, and have the function of magnifying and reducing the molten pool image.

[0040] The industrial digital camera has a light-sensing function, and its parameters can be automatically switched during arc ignition and arc extinguishing.

[0041] In practice, welders need to wear the weld pool observation helmet before welding. By changing their own body position and posture or manually adjusting the length and shape of the multi-link, the industrial digital camera is placed in the best position for observing the weld pool. Then, the industrial digital camera and the transparent screen of the optical chip are turned on, and welding work is then carried out.

[0042] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
