[0043] In view of the technical problems of the background technology, the present invention proposes a laser processing device 100 .

[0044] Reference Figure 1 and Figure 2 In one embodiment of the utility model, the laser processing equipment 100 includes an equipment body 10, a detection device 30 and an alarm device. The equipment body 10 is provided with a processing area 115; the detection device 30 is arranged in the equipment body 10; the alarm device is communicatively connected with the detection device 30 to issue an alarm when the detection device 30 detects a fire in the processing area 115.

Among them, the laser processing equipment 100 includes an equipment body 10 and a detection device 30 arranged on the equipment body 10. The equipment body 10 can be only a laser head 13 and a moving mechanism that drives the laser head 13 to move. The processing area 115 in the equipment body 10 is provided with a processing platform for placing the materials to be processed. The detection device 30 is used to detect whether there is a fire in the processing area 115. The detection device 30 can be a temperature sensor, which determines that a fire has occurred or there is a risk of fire when a higher temperature is detected. It can also be an optical sensor 31, which determines whether there is an open flame by detecting the light intensity. It can also be a detection device 30 such as a smoke alarm, or the detection device 30 can also be The image acquisition device such as a camera can determine the presence of a fire when at least one of flames and smoke is identified. When the detection device 30 detects a fire or determines that there is a risk of fire, the sensing signal can be transmitted to the alarm device so that the alarm device can sound an alarm to warn the user, so that the user can be informed of the fire in time and take corresponding measures to avoid safety accidents. The alarm device can sound an alarm by making the warning light stay on or flash, or by making a warning sound through a speaker, or by sending an alarm message to a terminal device connected to the laser processing equipment 100 for communication. A movable motion structure can also be set as an alarm device to sound an alarm by making the motion structure move, etc. In addition, in some embodiments, when the detection device 30 detects a fire, the laser processing equipment 100 can be controlled to stop processing.

[0046] Therefore, the technical solution of the present invention is to set a detection device 30 in the laser processing equipment 100 to timely detect the fire or fire risk in the laser processing equipment 100, and make the alarm device send an alarm signal, so that the user can be informed of the fire in time and take corresponding measures, thereby avoiding causing a fire and causing a production accident, thereby improving the safety of the use of the laser processing equipment 100.

[0047] In one embodiment of the present application, the detection device 30 is provided with a sensor 31, and the sensor 31 is used to detect at least one of flame, smoke, light intensity, and temperature.

[0048] In this embodiment, a sensor 31 is provided in the detection device 30. The sensor 31 may be a flame sensor, a smoke sensor, an optical sensor or a temperature sensor. The detection device 30 may be provided with only one type of sensor or may be provided with different types of sensors 31, so as to quickly and sensitively judge the fire condition and the existing fire risk according to the detection of different signals, thereby improving the sensitivity of fire detection.

[0049] Please refer to Figure 1 In one embodiment of the present application, the detection device 30 is disposed on the peripheral side of the processing area 115 .

[0050] It is understandable that during the operation of the laser processing equipment 100, there is a thermal effect between the laser beam and the material to be processed, that is, the risk of fire in the processing area 115 is relatively high. In this embodiment, the detection device 30 is arranged on the peripheral side of the processing area 115, so that the fire can be quickly discovered when the processing area 115 and the processing materials in the processing area 115 are on fire or about to catch fire, so that the user can deal with it in time to avoid more serious safety accidents. It should be noted that in this embodiment, the detection device 30 is arranged on the peripheral side of the processing area 115, which can be arranged around the processing area 115 or above the processing area 115, and is not limited here.

[0051] Please refer to Figures 2 to 6 In some embodiments of the present application, the detection device 30 includes at least two sensors 31, each of which is installed on the peripheral side of the processing area 115 and is spaced apart from each other.

[0052] In this embodiment, the detection device 30 is provided with at least two sensors 31, and each sensor 31 is installed at a different position around the processing area 115. With such a configuration, when the processing area 115 is large, it is possible to avoid the problem that a single sensor 31 is set or the detection devices 30 are installed in the same position, and the fire location is far away from the detection device 30, resulting in the detection device 30 being unable to detect the fire in time. The detection range and detection sensitivity of the detection device 30 are increased, and the safety of use of the laser processing equipment 100 is further improved.

[0053] It should be noted that the sensors 31 installed at different positions in the detection device 30 may be of the same type or of different types, or different types of sensors 31 may be arranged at the same position, which is not limited here.

[0054] Please refer to Figures 2 to 7In some embodiments of the present application, the laser processing equipment 100 is defined to have a front-to-back direction, and at least one sensor 31 is provided on the front side of the processing area 115; and / or, at least one detection device 30 is provided on the rear side of the processing area 115.

[0055] It can be understood that in the laser processing equipment 100, it is necessary to set a laser head 13 to emit a laser beam to the processing area 115 so as to process the processing materials placed on the processing area 115, and in the laser processing equipment 100, there is generally a position and direction that is convenient for the user to operate the equipment or to distinguish the materials, and the position is defined as the front of the laser processing equipment 100; in this embodiment, a sensor 31 is set at at least one of the front edge and the rear edge of the processing area 115, and the sensor 31 can be set at only one of the aforementioned positions, or at both positions at the same time; the sensor 31 of the detection device 30 can be installed at different positions according to actual needs. In some embodiments, the sensor 31 can also be set at the laser head 13 of the processing equipment 100, and the setting of the detection device 30 is more flexible.

[0056] Please refer to Figures 2 to 7 In some embodiments of the present application, at least two sensors 31 are provided at intervals on the front side of the processing area 115, at least two sensors 31 are provided at intervals on the rear side of the processing area 115, and at least one sensor 31 is provided on the laser head 13 of the device body 10.

[0057] In this embodiment, at least two sensors 31 are arranged at intervals along the edge of the processing area 115 on the front side of the processing area 115, and at least two sensors 31 are arranged at intervals along the edge of the processing area 115 on the rear side of the processing area 115, and a sensor 31 is arranged on the laser head 13 above the processing area 115. In this arrangement, the detection device 30 can monitor the processing area 115 in all directions, so as to promptly detect fire in the processing area 115, thereby improving the safety of the laser processing equipment 100.

[0058] Please refer to Figures 3 to 6 In some embodiments of the present application, the detection device 30 further includes a protective cover 32 , and the protective cover 32 is disposed on the sensor 31 .

[0059] In this embodiment, the detection device 30 further includes a shield 32, which is disposed on the side of the sensor 31 facing the processing area 115 to protect the sensor 31 and can be used to isolate high temperature and open flames, etc., so as to reduce the risk of damage to the sensor 31 when a fire occurs. In addition, according to different types of sensors 31, the structure of the shield 32 can be adaptively adjusted. For example, when the sensor 31 is a smoke sensor 31, a vent hole can be opened on the shield 32 so that smoke can flow to the sensor 31 to be sensed. When the sensor 31 is an optical sensor 31 for detecting the light intensity of the flame, at least part of the shield 32 can be made of a light-transmitting material; when the sensor 31 is a temperature sensor 31, the shield 32 can be made of a light-transmitting material without the function of isolating high temperature or can reduce the temperature limit judged as a fire, so that the shield 32 isolates part of the temperature. At this time, the sensor 31 transmits fire information when a lower preset temperature is detected. The specific structure of the shield 32 is not limited here.

[0060] Please refer to Figures 2 to 7 In some embodiments of the present application, the detection device 30 also includes a circuit board 33, the sensor 31 is disposed on the circuit board 33 and is electrically connected to the circuit board 33, and the circuit board 33 is electrically connected to the device body 10 and the alarm device.

In addition, when at least two sensors 31 are provided, the sensors 31 can also be provided on the same circuit board 33, and the circuit board 33 uniformly supplies power to each sensor 31 and processes the sensing signal of the sensor 31, and uniformly controls the operating state of each sensor 31. At this time, only the circuit board 33 is fixed to complete the installation of at least two sensors 31, which improves the installation convenience of the detection device 30. It should also be noted that the circuit board 33 can be directly fixed on the equipment body 10, or it can be installed through the fixing frame 36 as in the following embodiment, which is not limited here.

[0062] Combined with reference Figures 3 to 6 In some embodiments of the present application, the detection device 30 further includes a fill light 34 , which is disposed on the circuit board 33 and is disposed toward the processing area 115 .

In addition, the fill light 34 increases the brightness of the processing area 115, which can also improve the processing accuracy and is also convenient for observing the processing process and the processing status of the product. Among them, the light-emitting surface of the fill light 34 is directly exposed to the outside or covered with a light guide cover 35 in the following embodiment.

[0064] Please refer to Figures 3 to 6 In some embodiments of the present application, the detection device 30 further includes a light guide cover 35 , and the light guide cover 35 is disposed on the light emitting surface of the fill light 34 .

[0065] In this embodiment, the detection device 30 also includes a light guide cover 35 covered on the light emitting surface of the fill light 34. The light guide cover 35 can be used to guide the light emitted by the fill light 34 to be emitted evenly. The light emitting surface of the light guide cover 35 is spherical, so that the light emitted by the fill light 34 can be emitted evenly in all directions to form a diffuse reflection effect, thereby avoiding differences in brightness in the processing area 115. In addition, the light guide cover 35 can also protect the fill light 34, thereby preventing the fill light 34 from being directly exposed to the outside world and easily damaged.

[0071] In this embodiment, when the detection device 30 is provided with a fill light 34 and a light guide 35, the light guide 35 can be separately provided or integrally provided with the fixing frame 36.
