[0013] Compared with the prior art, the utility model provides a laser cutting head anti-collision structure, which has the following beneficial effects:

[0014] 1. The anti-collision structure of the laser cutting head is provided with a sensor mounting plate, a strong magnet at the bottom and a strong magnet at the top. The first connecting plate and the second connecting plate are connected by magnetic attraction, which is a non-rigid connection. The laser cutting head and the first connecting plate can be dislocated after a collision to avoid the collision force acting directly on the laser cutting head, which can provide a certain protection for the laser cutting head.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0023] Refer to Figures 1-4, a laser cutting head anti-collision structure, including a laser cutting head 1. A connecting piece 2 is fixedly connected to the top of the laser cutting head 1. The top of the connecting piece 2 is connected to a first connecting plate 3. A fixing hole 14 is opened at a position near the middle of the top of the first connecting plate 3. A bottom strong magnet 15 is arranged inside the fixing hole 14. The first connecting plate 3 and the bottom strong magnet 15 are fixedly sleeved. Cutting head mounting holes 16 are opened at positions near the left and right edges of the first connecting plate 3. The top of the first connecting plate 3 is magnetically connected to a second connecting plate 4. A top strong magnet 19 is fixedly sleeved at a position near the middle of the bottom of the second connecting plate 4. The arrangement of the bottom strong magnet 15 and the top strong magnet 19 enables the first connecting plate 3 and the second connecting plate 4 to be connected conveniently and stably. At the same time, after the laser cutting head 1 collides, they can be effectively separated to protect the laser cutting head 1 and also facilitate later resetting. Component connecting holes 18 are opened at positions near the front and back of the bottom of the second connecting plate 4. First threaded holes 13 are opened at positions near the front and back of the first connecting plate 3. Second threaded holes 17 are opened at positions near the front and back of the second connecting plate 4. A sensor mounting plate 11 is fixedly connected to the left side near the middle of the first connecting plate 3. A baffle 12 is fixedly connected to the left side near the middle of the second connecting plate 4. The arrangement of the sensor mounting plate 11 and the baffle 12 can monitor the states of the first connecting plate 3 and the second connecting plate 4 in real time. When the first connecting plate 3 drives the baffle 12 to become dislocated, a signal is transmitted to the control system in time, so that the control system stops the whole device and cuts off the laser light to avoid damage to the whole system. When the fixing hole 14 on the first connecting plate 3 sleeves the bottom strong magnet 15, the fixing hole 14 presents a concave state. When the bottom of the second connecting plate 4 sleeves the top strong magnet 19, the bottom of the second connecting plate 4 presents a convex state. The top of the bottom strong magnet 15 and the bottom of the top strong magnet 19 are opposite magnetic poles. The first connecting plate 3 and the second connecting plate 4 are magnetically connected through the bottom strong magnet 15 and the top strong magnet 19. When the first connecting plate 3 and the second connecting plate 4 are in contact with each other, the top of the bottom strong magnet 15 is in contact with the bottom of the top strong magnet 19.

[0024] Refer to Figures 1-3As described above, limiting plates 10 are fixedly connected to the positions of the first connecting plate 3 and the second connecting plate 4 close to the front and back of the sensor mounting plate 11 and the baffle 12. A first connecting bolt 5 is threadedly connected to the inner side of the first threaded hole 13. A fixing block 7 is clamped between the first connecting bolt 5 and the second connecting bolt 6 and the first connecting plate 3 and the second connecting plate 4. One end of the fixing block 7 close to the sensor mounting plate 11 is fixedly connected to a connecting block 8. One end of the connecting block 8 close to the sensor mounting plate 11 is welded with a steel wire rope 9. The steel wire rope 9 is used to connect the first connecting plate 3 and the second connecting plate 4, so as to prevent the first connecting plate 3 from colliding with the ground together with the laser cutting head 1 when it is dislocated, and secondary damage to the laser cutting head 1 can be avoided. One end of the steel wire rope 9 close to the sensor mounting plate 11 is located at the bottom on the side close to the center of the first connecting plate 3 and the second connecting plate 4 of the limiting plate 10. A second connecting bolt 6 is threadedly connected to the inner side of the second threaded hole 17.

[0025] In the present utility model, during a collision, the first connecting plate 3 and the second connecting plate 4 are separated. Since there is a steel wire rope 9 connecting them, the laser cutting head 1 and the first connecting plate 3 will not fall to the ground, avoiding secondary collision of the laser cutting head 1. At the same time, after the distance sensor installed on the second connecting plate 4 fails to detect the baffle 12 on the first connecting plate 3, it will send a signal to the control system. The control system shuts down the entire device and cuts off the laser, avoiding damage to the entire system. At this time, the maintenance personnel check the degree of collision. After confirming that there is no mechanical damage, the first connecting plate 3 and the second connecting plate 4 are magnetically reset again through the bottom strong magnet 15 and the top strong magnet 19. The device clicks the reset signal and can then be used continuously. If there are damaged components, after replacement, the above steps are executed and the device can be used again.

[0026] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
