Description

Technical Field

[0001] This utility model relates to the field of personal protective equipment, and in particular to a welding mask with laser protection. Background Technology

[0002] The technological background of laser welding stems from the relentless pursuit of "better, faster, and stronger" connection methods by high-end manufacturing industries. Its transition from the laboratory to industrialization and widespread adoption is attributed to the disruptive advancements in laser technology (especially fiber lasers) and its perfect integration with automation technology. Today, it has become an indispensable core process in high-end equipment manufacturing, particularly in the new energy vehicle and power battery industries, and is one of the important indicators of a country's advanced manufacturing level. As laser welding gradually penetrates into industrial production processes, it will inevitably place higher demands on the safety protection of personnel and equipment during the laser welding process.

[0003] Existing laser welding protection still relies on traditional handheld protective equipment. Laser welding protection must adopt more stringent protection strategies. However, existing ordinary welding masks do not meet the protection requirements for laser welding. The masks may be softened or even penetrated under the action of laser, causing permanent damage to the operator's eyes or face. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a welding mask with laser protection to protect the human eye and avoid temporary and permanent damage to the human eye caused by laser.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A welding mask with laser protection includes a helmet shell body, a laser protection filter, and a hat strap assembly fixedly connected to the helmet shell body. Its innovation lies in the following: the front of the helmet shell body has a viewing window, on which a laser protection filter is installed; the front of the helmet shell body is also covered with a carbon fiber cover plate.

[0006] The laser protective filter includes optical glass and an acrylic sheet, and the optical glass and the acrylic sheet are bonded together.

[0007] The laser protective filter includes optical glass and a liquid crystal light valve, and the optical glass and the liquid crystal light valve are bonded together.

[0008] The laser protective filter is also covered with carbon fiber cover plates on the upper and lower sides of the liquid crystal light valve.

[0009] The hatband assembly includes a head circumference fixing strap and a top pressure strap, the head circumference fixing strap and the top pressure strap are hinged together, and the hatband assembly is fixedly connected to the hat shell body by a buckle.

[0010] The head circumference fixing strap also has an adjustment button for adjusting the tightness.

[0011] In summary, the advantages of the present invention over traditional methods are as follows: the present invention uses a certain thickness of carbon fiber thermosetting sheet (or a thermoplastic material containing a certain proportion of glass fiber) to absorb and block laser light by utilizing the high ignition point of carbon fiber and glass fiber, thereby providing protection against laser light.

[0012] This invention has a simple structure and is easy to wear and operate. When using it, you only need to wear the mask. The laser welding mask of this invention is made of lighter materials and can achieve a good protective effect for laser protection. Attached Figure Description

[0013] The foregoing and other objects, features and advantages of the present invention will become apparent from the following detailed description taken in conjunction with the accompanying drawings.

[0014] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 for Figure 1 Exploded structure diagram; Figure 3 This is a schematic diagram of another structure of the present invention; Figure 4 for Figure 3 Exploded structure diagram; The components include: 1. Head shell body; 1-1. Vision window; 2. Carbon fiber cover plate; 3. Headband assembly; 3-1. Head circumference fixing strap; 3-2. Top pressure strap; 3-3. Buckle; 3-4. Adjustment button; 4. Laser protective filter; 4-1. Optical glass; 4-2. Acrylic plate; 4-3. Liquid crystal light valve. Detailed Implementation

[0015] Based on the preferred embodiments of this utility model, and through the following description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.

[0016] The present invention will be further described with reference to the following figures: like Figure 1-4As shown, a welding mask with laser protection includes a helmet body 1, a laser protection filter 4, and a hat strap assembly 3 fixedly connected to the helmet body 1. The helmet body 1 has a viewing window 1-1 on its front side, and the laser protection filter 4 is mounted on the viewing window 1-1. The front side of the helmet body 1 is also covered with a carbon fiber cover plate 2. The laser protection filter 4 of this invention can be a filter formed by bonding optical glass 4-1 and acrylic plate 4-2 together to block laser light, or it can be a laser protection filter 4 comprising optical glass 4-1 and a liquid crystal light valve 4-3 bonded together. The liquid crystal light valve 4-3 mentioned in this invention is a product developed and manufactured by our company with patent publication number CN221998182U. The optical glass 4-1 is coated using a coating process. After the optical glass is bonded to the acrylic sheet, it forms a filter with non-adjustable brightness, which is suitable for general simple laser welding scenarios. The optical glass 4-1, together with the structure of the liquid crystal light valve 4-3, can automatically adjust the brightness of the light valve according to different working conditions during the welding process, thereby protecting the eyes.

[0017] In the implementation of this utility model, the acrylic plate 4-2, the optical glass 4-1, and the liquid crystal light valve 4-3 are usually installed on the field of view window 1-1 after being installed through their filter frames.

[0018] like Figure 3-4 As shown, the laser protective filter 4 is also covered with carbon fiber cover plates 2 on the upper and lower sides of the liquid crystal light valve 4-3. This provides comprehensive protection.

[0019] like Figure 2 , 4 As shown, the hatband assembly 3 includes a head circumference fixing strap 3-1 and a top head pressure strap 3-2. The head circumference fixing strap 3-1 and the top head pressure strap 3-2 are hinged together. The hatband assembly 3 is fixedly connected to the hat shell body 1 via a buckle 3-3. The head circumference fixing strap 3-1 also has an adjustment button 3-4 for adjusting the tightness. The hatband assembly described in this invention can also take the form of other soft straps.
