[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] For large-format laser cutting, the cutting worker cannot clearly observe the laser cutting status. In order to observe the cutting status, the worker will stand on the table and follow the beam, which undoubtedly increases the damage to the worker caused by laser radiation, and there is also the risk of being hit by the beam, which seriously affects the worker's safety. At the same time, if the laser cutting head hits the lifted plate and is not discovered in time, it will affect the stability and quality of subsequent cutting, and may even cause permanent damage to the cutting head, resulting in great losses; if the air pressure is unstable during laser cutting, the plate will not be cut through. At this time, the worker needs to stop the machine in time to adjust the air pressure before cutting. If it is not discovered in time, the cutting will continue, and the cut plate cannot be removed from the motherboard. The cut area of the plate cannot be used, resulting in waste of the plate. The following describes a monitoring device for a laser cutting machine provided by some embodiments of the present invention in conjunction with the accompanying drawings.
[0023] Example 1:
[0024] In order to enable the staff to observe the working status of the laser cutting machine in real time, so as to promptly discover the problems that may occur during the working process, combined with Figure 1-Figure 4As shown, a monitoring device for a laser cutting machine is proposed, by setting a main body mechanism 1, a connecting mechanism 2 is provided on the main body mechanism 1, a monitoring camera 4 is provided on one side of the connecting mechanism 2, and a fixing mechanism 3 is provided on the monitoring camera 4. The main body mechanism 1 and the monitoring camera 4 cooperate to perform real-time monitoring of the laser cutting, which saves the workload of the staff. The position of the fixing mechanism 3 is fixed by the connecting mechanism 2, and the monitoring camera 4 can be easily disassembled and assembled through the fixing mechanism 3, and the stains on the explosion-proof shield can be easily cleaned, thereby maintaining a good monitoring state.
[0025] In order to enable the device to easily disassemble and assemble the monitoring camera 4, a fixing mechanism 3 is proposed. By fixing a fixing plate 301 on one side of the protective shell 202, an electric telescopic rod 302 is installed at the bottom of the fixing plate 301, and the movable end of the electric telescopic rod 302 is fixedly connected to the connecting plate 303. The bottom of the fixing plate 301 is rotatably connected to a rotating plate 304, and the bottom of the rotating plate 304 is fixedly connected to a circular plate a. One side of the connecting plate 303 is fixedly connected to a support plate 305, and one side of the support plate 305 is fixedly connected to a fixing ring 306. A circular fixing block 307 is detachably installed on the top of the monitoring camera 4, and a cleaning member 306 is provided on one side of the fixing ring 306 for easily cleaning the lens of the monitoring camera 4. The component 308, the diameter of the circular fixed block 307 is larger than the diameter of the fixing ring 306, the position of the electric telescopic rod 302 and the rotating plate 304 is fixed by the fixing plate 301, the position of the support plate 305 is fixed by the connecting plate 303, the position of the fixing ring 306 is fixed by the support plate 305, the height of the fixing ring 306 is adjusted by the electric telescopic rod 302, the monitoring camera 4 is installed and fixed to the circular fixed block 307, the monitoring camera 4 is passed through the fixing ring 306, at this time the circular fixed block 307 is engaged with the top of the fixing ring 306, the electric telescopic rod 302 is adjusted again, and the monitoring camera 4 is adjusted to a suitable height, so as to monitor the laser cutting process in real time.
[0026] The main body 1 consists of an operating table 101, a camera display 102 connected to the monitoring camera 4, and a laser cutting head 103 installed in a protective shell 202. The image of the monitoring camera 4 is displayed through the camera display 102, which is convenient for the staff to view. The connecting mechanism 2 includes a protective shell 202, and a fixing frame 201 is fixed on the protective shell 202. The protective shell 202 is fixed by the fixing frame 201, and the position of the laser cutting head 103 and the fixing mechanism 3 is fixed through the protective shell 202. At the same time, the outer surface of the laser cutting head 103 can be protected to a certain extent.
[0027] Example 2:
[0028] On the basis of Example 1, the technical solution proposed in Example 1 is used to solve the problem in the prior art that workers stand on the table and follow the beam in order to observe the cutting status, which undoubtedly increases the damage to workers caused by laser radiation and there is also a risk of being hit by the beam, seriously affecting the safety of workers. However, after long-term use, the surface of the explosion-proof shield of the monitoring camera 4 will have stains. If it is not cleaned in time, the monitoring effect of the device will be affected.
[0029] In order to ensure the real-time monitoring of the laser cutting process by the device, combined with Figure 1 and Figure 3 as well as Figure 4 As shown, a cleaning assembly 308 is proposed, which is fixedly connected to a cross block 3081 at the bottom of the circular plate a, and a circular plate b is fixedly connected to the top of the circular fixed block 307. A cross groove 3082 is provided on the circular plate b, and a connecting block 3083 is fixedly connected to one side of the fixing ring 306. A square hole is provided on one side of the connecting block 3083, and two magnetic plates a3084 are fixedly connected in the square hole. A fixing rod is rotatably connected in the square hole, and magnetic plates b3085 are fixedly connected to the top of the two sides of the fixing rod respectively. The magnetic plates a3084 and the magnetic plates b3085 attract each other, and the bottom end of the fixing rod is fixedly connected to an arc-shaped cleaning rack 3086. A cleaning cloth is detachably installed on the inner side of the arc-shaped cleaning rack 3086, and a micro-drive for driving the rotating plate 304 is installed on the top of the fixed plate 301. The motor adjusts the electric telescopic rod 302 so that the cross slot 3082 on the circular plate b is engaged with the cross block 3081 on the circular plate a. At this time, the micro motor drives the rotating plate 304 to rotate, so that the circular plate a drives the circular plate b to rotate, and the circular fixed block 307 drives the monitoring camera 4 to rotate. At this time, the magnetic plate b3085 on one side of the fixed rod is connected to the magnetic plate a3084 at the lower part of the square hole, thereby fixing the position of the arc cleaning frame 3086, so that the explosion-proof shield rotates by friction on the surface of the cleaning cloth. When cleaning is completed, the fixed rod is rotated so that the magnetic plate b3085 on the other side of the fixed rod is connected to the magnetic plate a3084 at the upper part of the square hole, thereby avoiding the arc cleaning frame 3086 from blocking the monitoring screen and ensuring the monitoring effect of the device.
[0030] The head of the monitoring camera 4 is detachably equipped with an explosion-proof shield. If there are stains on the surface of the explosion-proof shield that are difficult to wipe off, affecting the shooting clarity, it is only necessary to replace a new explosion-proof shield without replacing the entire camera, saving the user's usage costs.
