Description

Technical Field

[0001] The utility model belongs to the technical field of laser welding machines, and in particular relates to a head-mounted protective mechanism for laser welding machines. Background Art

[0002] Laser welder, also commonly known as laser welder or laser welder, is a machine used for laser welding in material processing. Laser welding uses high-energy laser pulses to locally heat the material in a small area. The energy of the laser radiation diffuses into the interior of the material through heat conduction, melting the material to form a specific molten pool. However, when the laser welder is welding, the laser emits strong light, and workers often wear goggles or masks for eye protection.

[0003] However, when wearing eye masks or face masks, when workers need to observe the welding of products, they often take off the eye masks or face masks to observe. However, this method is cumbersome and needs to be put on again. At the same time, the smoke and dust generated during welding diffuses in the air and is easily inhaled into the lungs by workers, causing discomfort.

[0004] Based on this, a head-mounted protective mechanism for laser welding machine is designed, which combines an extruded breathing mask, a transparent eye mask and a flip-up laser protective eye mask. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a head-mounted protective mechanism for a laser welding machine. The specific technical solution is as follows:

[0006] A head-mounted protective mechanism for a laser welder comprises a breathing mask, a head-mounted elastic rope for head wearing is installed on the back of the breathing mask, a transparent eye mask for eye protection against foreign objects is fixed on the upper part of the breathing mask, a laser protective eye mask for laser protection is rotatably installed on the upper end of the transparent eye mask through a resistance bearing, a sealing rubber ring for sealing with the face is provided at the edge of the breathing mask, and a non-woven filter is fixedly installed on the breathing hole in the middle of the breathing mask through a magnetic positioning mechanism.

[0007] Preferably, a clamping ring is integrally formed on the edge of the sealing rubber ring, a convex ring is integrally formed on the edge of the breathing mask, and the clamping ring is clamped on the outside of the convex ring, and a buffer cavity for buffering is provided inside the sealing rubber ring.

[0008] Preferably, the magnetic positioning mechanism includes a cover ring and a mesh cover integrally formed with the cover ring, and the mesh cover is covered on the outside of the non-woven filter, a first magnet is fixed in a groove opened at the edge of the cover ring, a second magnet is fixed in a groove opened at the edge of the breathing hole in the middle of the breathing mask, and the first magnet and the second magnet are attracted to each other by magnetic force.

[0009] Preferably, the mesh cover plate is a mesh structure.

[0010] Preferably, two headband elastic cords are provided.

[0011] Preferably, the upper portion of the laser protective eyewear is arc-shaped.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the laser protective eye mask installed on the upper end of the transparent eye mask is rotated by a resistance bearing, and the transparent eye mask is fixed on the upper part of the breathing mask, so that the breathing mask can be worn on the head through the head-mounted elastic rope, thereby realizing the protection of the eyes during laser welding by the transparent eye mask and the laser protective eye mask when the breathing mask is worn, thereby improving the protection performance of the head-mounted protection mechanism, and the non-woven fabric filter installed in the middle of the breathing mask through the magnetic positioning mechanism enables the breathing mask to isolate dust in the air through the non-woven fabric filter, thereby reducing the inhalation of welding fumes by workers during laser welding, and the sealing rubber ring arranged on the edge of the breathing mask facilitates the breathing mask to better fit the face through the sealing rubber ring.

[0020] In the present embodiment, the laser protective eye mask 4 mounted on the upper end of the transparent eye mask 3 is rotatably mounted by a resistance bearing, and the transparent eye mask 3 is fixed to the upper part of the breathing mask 1, so that the breathing mask 1 is worn on the head through the head-mounted elastic rope 2, thereby realizing the protection of the eyes during laser welding by the transparent eye mask 3 and the laser protective eye mask 4 when the breathing mask 1 is worn, thereby improving the protection performance of the head-mounted protection mechanism, and the non-woven fabric filter 11 installed in the middle of the breathing mask 1 through the magnetic positioning mechanism, so that the breathing mask 1 is isolated from dust in the air through the non-woven fabric filter 11, thereby reducing the inhalation of welding fumes by workers during laser welding, and the sealing rubber ring 5 arranged on the edge of the breathing mask 1 facilitates the breathing mask 1 to better fit the face through the sealing rubber ring 5.

[0021] Specifically, a clamping ring 6 is integrally formed on the edge of the sealing rubber ring 5 , a convex ring 7 is integrally formed on the edge of the breathing mask 1 , and the clamping ring 6 is clamped on the outside of the convex ring 7 , and a buffer cavity 8 for buffering is provided inside the sealing rubber ring 5 .

[0022] In this embodiment, the clamp ring 6 is integrally formed on the edge of the sealing rubber ring 5, and the clamp ring 6 is clamped outside the buffer cavity 8 integrally formed on the edge of the breathing mask 1, so as to facilitate the connection between the sealing rubber ring 5 and the breathing mask 1. The buffer cavity 8 provided in the sealing rubber ring 5 facilitates the deformation of the sealing rubber ring 5 when it is squeezed, so that the sealing rubber ring 5 is easy to fit the face.

[0023] Specifically, the magnetic positioning mechanism includes a cover ring 9 and a mesh cover 10 integrally formed with the cover ring 9, and the mesh cover 10 covers the outside of the non-woven filter 11, a first magnet 12 is fixed in a groove at the edge of the cover ring 9, a second magnet 13 is fixed in a groove at the edge of the breathing hole in the middle of the breathing mask 1, and the first magnet 12 and the second magnet 13 are attracted to each other by magnetic force, and the mesh cover 10 is a mesh structure.
