Observation patch with multiple eye shield structures for laser welding detection tool

Abstract

The invention discloses an observation patch with multiple eye shield structures for a laser welding detection tool, and relates to the technical field of laser welding. The observation patch is specifically provided with a mirror bracket and a connecting shaft; a transparent lens is installed at the inner side of the mirror bracket, a silica gel attaching pad is fixedly arranged at the rear sideof the mirror bracket, the left and right sides of the silica gel attaching pad are each provided with a connector, a side head strap is connected to the rear sides of the connectors, a head strap clamp is arranged at the rear side of the head strap, a top head strap is connected to the upper portion of the head strap clamp, an elastic connecting piece is installed at the outer side of the side head strap, and a fixing clamp is arranged at the rear side of the elastic connecting piece. According to observation patch with multiple eye shield structures for the laser welding detection tool, dueto the crossed structure formed by the side head strap and the top head strap, the patch can be matched with the shape of the human head, the wearing stability of the device is improved, the patch isprevented from falling down, the two hands of the user can be liberated, and use is more convenient.

Description

technical field [0001] The invention relates to the technical field of laser welding protection devices, in particular to an observation goggle with multiple eye protection structures for laser welding detection. Background technique [0002] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. Laser welding is one of the important aspects of the application of laser material processing technology. Due to its unique advantages, it has been successfully applied to the precision of micro and small parts. During welding, laser welding needs to observe the welding effect in real time in order to make adjustments. However, laser welding will produce severe flashes. Excessive flashes are harmful to the eyes. If you do not wear leather or protective glasses, it is easy to damage the eyes. Therefore, Appropriate eye protection must be worn when observing laser welding work. [0003] The existing protective device for ...

[0002] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. Laser welding is one of the important aspects of the application of laser material processing technology. Due to its unique advantages, it has been successfully applied to the precision of micro and small parts. During welding, laser welding needs to observe the welding effect in real time in order to make adjustments. However, laser welding will produce severe flashes. Excessive flashes are harmful to the eyes. If you do not wear leather or protective glasses, it is easy to damage the eyes. Therefore, Appropriate eye protection must be worn when observing laser welding work

[0003] The existing protective device for laser welding observation glasses has a relatively simple structure, with only one layer of filter lens, which is less stable when worn, easy to slip off, and has a fixed structure, which cannot be adjusted in real time according to the user. It is flexible and comfortable to wear At the same time, it is impossible to adjust the filter effect of the glasses according to the different flash brightness during welding. The use mode is relatively single, and it cannot adapt to the changing working environment and needs of welding.

[0004] A kind of factory welding goggles disclosed in the Chinese Utility Model Patent Application Publication No. CN207168638U. Although the factory welding goggles are provided with a foldable folding structure, they can not only protect the eyes and faces of workers, but also facilitate storage. And carry, without hand support, which greatly facilitates the electric welding work of electric welding workers. However, the welding goggles in this factory have only one layer of filter lens design. When performing welding work, it is often necessary to observe the welding effect with the naked eye after welding a part. It is not convenient to switch the filter effect according to the different working conditions
