Specific embodiment
Below in conjunction with attached drawing, invention is further described in detail.
Referring to Figures 1 and 2, a kind of laser cutting machine, including machine body 1 and alarm device 2.Machine body 1 is used to put
It sets metal plate plate and sheet metal is cut.After completing to the cutting of sheet metal current on machine body 1, need
The sheet metal placed on 1 workbench 11 of machine body is replaced, workbench 11 is along 1 length direction court of machine body at this time
The end of reloading of machine body 1 is moved, after having replaced sheet metal, the cutting work station that workbench 11 restores, and then to new
Sheet metal cut.In remetal material, there are personnel to enter the feeding end of machine body 1 at this time, be easy to make
At safety accident.Alarm device 2 is used to be monitored the danger zone at the feeding end of machine body 1, when there is personnel to swarm into
It when danger zone, outwardly sends a warning, and then intruder is reminded, reduce the possibility that safety accident occurs.Swash
Light cutting machine further includes work light 3, and work light 3 is connected with alarm device 2 accesses circuit.And then in alarm device 2
When normal power supply, work light 3 is lighted, and when work light 3 extinguishes, then it is abnormal in power-off to represent 2 source of alarm device
State, and then staff is prompted to overhaul in time to alarm device 2.
Referring to Fig. 2, alarm device 2 includes detection module 21, central processing module 22, alarm module 23 and workbench 11
State detection module 21.The setting of detection module 21 is at 1 feeding end of machine body, and detection module 21 is to the people close to machine body 1
Body is detected, and sends human body signal to central processing module 22 when detecting human body；Central processing module 22 receives simultaneously
In response to the human body signal that detection module 21 issues, to 23 signal an alert of alarm module；Alarm module 23 is received and is responded
The alarm signal that central processing module 22 issues, outwardly alert.11 state detection module 21 of workbench for pair
11 motion state of workbench is detected, and then personnel swarm into danger zone and workbench 11 is towards 1 feeding of machine body when have
End controls 11 stop motion of workbench of machine body 1 by central processing module 22 when being moved, and then prevents to swarming into
Person damages.
Referring to Figure 1 and Figure 3, detection module 21 includes the detection stake 211 that the two sides at 1 feeding end of machine body are arranged in；Inspection
Surveying module 21 further includes that two groups of laser emitters 212 and laser induced switch 213(are not limited to two groups), laser emitter 212
It is horizontally fixed in the detection stake 211 of side, laser induced switch 213 is fixed in the detection stake 211 of the other side.Laser emission
The laser rays that device 212 emits is irradiated on the photographic department of laser induced switch 213.Central processing module 22 is using STM32 intelligence
Chip module, alarm module 23 include combined aural and visual alarm 231, and combined aural and visual alarm 231 simultaneously responds the sending of central processing module 22
Alarm signal outwardly issues sound-light alarm information.When there are personnel to swarm into danger zone, laser emitter 212 is issued
Laser block, when the photographic department of laser induced switch 213 loses laser irradiation, and then laser induced switch 213 is to centre
It manages module 22 and sends human body signal, so that central processing module 22 receives human body signal, and issue and report to combined aural and visual alarm 231
Alert signal after combined aural and visual alarm 231 receives the alarm signal of the sending of central processing module 22, outwardly issues sound-light alarm letter
Breath, and then dangerous tip is carried out to intruder and the operator of laser cutting machine is prompted.
Referring to Fig. 3 and Fig. 4,11 state detection module 21 of workbench includes distance measuring sensor 241.It detects fixed in stake 211
There is a testing stand 242, distance measuring sensor 241 is horizontally fixed on testing stand 242 and towards the workbench of machine body 1 11.It is logical
The distance for crossing workbench 11 of the distance measuring sensor 241 to distance measuring sensor 241 apart from machine body 1 is detected and be will test
Range information be sent to central processing module 22.When distance measuring sensor 241 detect distance values become larger by small, then say
Bright workbench 11 is moved by feeding end towards cut end.When the distance values that distance measuring sensor 241 detects are by gradually becoming greatly
It is small, then illustrate that workbench 11 is moved from cut end to feeding end.11 horizontal movement of workbench is driven by horizontal drive motor 12
Dynamic, horizontal drive motor 12 uses servo drive motor, when central processing module 22 receives the human body of the sending of detection module 21
Signal and central processing module 22 identify workbench 11 towards when 1 feeding end motion of machine body, and central processing module 22 is controlled
Horizontal drive motor 12 processed stops driving.To prevent when there is personnel to swarm into danger zone, the movement of workbench 11 is to swarming into
Person damages.
Referring to Fig. 4 and Fig. 5, two groups of laser emitters 212 and laser induced switch 213 are located on different height and positions,
One group is located at detection 211 top of stake, and one group is located at detection 211 lower part of stake, and then the laser rays of two laser emitters 212 transmitting
A vertical laser plane is formed, to prevent intruder from avoiding the laser rays that laser emitter 212 emits.Detect stake 211
Upper setting altitude scale 2111.Vertical sliding slot 2112 is arranged in detection stake 211, and 2112 length side along the chute is arranged in sliding slot 2112
To the T-type sliding block 214 of sliding, laser reflector and laser induced switch 213 are separately fixed at the T-type cunning that stake 211 is detected in two sides
On block 214, T-type sliding block 214 is provided with connection bolt 215 that is axial horizontal and being threadedly coupled with T-type sliding block 214, passes through company
The abutting of connecting bolt 215 and detection stake 211, and then T-type sliding block 214 is fixed on corresponding height and position.To which laser is sent out
Emitter 212 and laser induced switch 213 are realized in the function that vertical direction and detection stake 211 are slidably connected, and then user's energy
Enough actually detected effects according to workshop laser emitter 212 and laser induced switch 213, to laser emitter 212 and laser
The height and position of inductive switch 213 is adjusted, to realize to the better detection effect of intruder.Logical energy altitude scale 2111
Setting facilitates staff to carry out height to laser emitter 212 and laser induced switch 213 and is configured.
The implementation principle of the present embodiment are as follows:
When machine body 1 is cut by laser sheet metal, by alarm device 2 to positioned at 1 feeding end of machine body
Whether someone, which swarms into, for danger zone is detected.When there is personnel to swarm into danger zone, intruder is to laser emitter 212
The laser of sending causes to block, and then laser induced switch 213 loses laser irradiation, to send human body to central processing module 22
Signal so that central processing module 22 receives human body signal, and issues alarm signal, sound-light alarm to combined aural and visual alarm 231
After device 231 receives the alarm signal of the sending of central processing module 22, sound-light alarm information is outwardly issued.Pass through ranging simultaneously
The distance that the distance of workbench 11 of the sensor 241 to distance measuring sensor 241 apart from machine body 1 is detected and be will test
Information is sent to central processing module 22, when the distance values that distance measuring sensor 241 detects are by gradually becoming smaller greatly and central processing
When module 22 receives human body signal, the stalling of 22 controlled level driving motor 12 of central processing module.
The embodiment of present embodiment is presently preferred embodiments of the present invention, not limits protection of the invention according to this
Range, therefore: the equivalence changes that all structures under this invention, shape, principle are done, should all be covered by protection scope of the present invention it
It is interior.
