Description

Technical Field

[0001] The present invention relates to the field of welding and cutting, and more specifically, to laser protective glasses based on an Internet of Things welding system. Background Art

[0002] Laser, the full name of which is "light amplification by stimulated emission of radiation", is a special kind of light. The main difference between it and traditional light is that the laser beam has the characteristics of monochromaticity, unidirectionality and coherence, which makes the light with extremely high focusing performance and invisible to the naked eye 100 times brighter than ordinary light sources.

[0003] Due to the invisibility and high-energy focusing of lasers, it is easy to cause irreversible damage to our bodies, especially our eyes, without people being on guard.

[0004] With the increasing popularity of laser applications, laser protective glasses have also emerged. However, traditional laser glasses

[0005] It is just a pair of glasses with laser protection. Although most people will wear protective glasses to prevent laser damage to their eyes, a considerable proportion of operators will ignore the importance of wearing glasses and be exposed to laser radiation, causing irreparable losses. Summary of the invention

[0006] In view of the problems existing in the prior art, the present invention provides a laser protective glasses based on the Internet of Things welding system, which can sense the input signal of the device after being worn through the sensor on the laser protective glasses, and then output and send the processed output signal to the laser power supply or smart device through WIFI or Bluetooth through the control unit of the protective glasses, open the safety setting switch and channel for the laser device or smart device, and finally output laser energy.

[0007] This invention can effectively prevent operators from starting laser power supplies or smart devices without wearing protective glasses, thereby protecting operators from harm caused by laser equipment.

[0008] In order to solve the above technical problems, the technical solution adopted by the present invention is: to provide a laser protective glasses based on the Internet of Things welding system, including: the device includes four parts: laser protective glasses, a power module, a sensor unit, and a control unit;

[0010] Laser protective glasses based on an Internet of Things welding system include laser protective glasses, a power module, a sensor unit and a control unit;

[0011] The laser protective glasses have two laser-proof glass lenses, a frame and two temples. The upper side of the frame is a cavity to form a glasses cavity channel, and the middle of the temples is a cavity to form a temple cavity channel.

[0012] The sensor unit is installed in the middle of the eyeglass cavity channel, and a nose pad slide groove is provided in the middle of the eyeglass frame below the sensor unit, and the eyeglass nose pad can be inserted into the nose pad slide groove and move up and down along the nose pad slide groove; a nose pad trigger rod is provided above the eyeglass nose pad, and when the eyeglass nose pad is forced to slide upward along the nose pad slide groove, the nose pad trigger rod is driven to move toward the sensor unit and trigger the sensor sensing device to generate an action signal;

[0013] The control unit is installed in a temple cavity channel; the control line of the sensor unit is connected to the control unit through the glasses cavity channel and the temple cavity channel, and can transmit the action signal generated by the upward movement of the glasses nose pad to the control unit;

[0015] Furthermore, the control unit is connected to the external laser power supply through a wireless signal or a Bluetooth signal. The control unit also includes a PCB circuit board and a wiring terminal. The PCB circuit board has a control circuit and a chip for receiving signals and transmitting WIFI or BLUETOOTH signals to the outside. The wiring terminal is used to connect the control line from the sensor.

[0016] Furthermore, a power switch and a power indicator light are provided on the temples, and the power switch and the power indicator light are connected to the control unit, and the power indicator light displays the power-on status of the control unit and the signal matching status between the control unit and the laser power supply. The power of the control panel can be turned on and off by long pressing the power switch button.

[0020] After the nose pads of the laser protective glasses come into contact with the operator, the nose bridge will push the nose pads upward along the slide slot due to the weight of the glasses, and the moving nose pad trigger rod will push the mechanical switch upward or approach the proximity switch to trigger the signal. After receiving the signal from the sensor unit, the control unit sends an enable signal to the laser power supply or smart device in the form of WIFI / BLUEETOOTH, and the laser power supply can then output laser energy.

[0021] When the worker takes off his glasses, the nose pads fall back to their original initial position.

[0022] The laser protective glasses device based on the Internet of Things welding system can effectively prevent operators from starting the laser power supply or smart device without wearing any protective equipment, thereby avoiding harm to the operator caused by radiation from the laser equipment.
