[0050] 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.

[0051] The core of the utility model is to provide a fully automatic laser cutting machine, which can ensure positioning accuracy while achieving high laser cutting efficiency.

[0052] Please refer to Figure 1 The present invention provides a fully automatic laser cutting machine, comprising a laser cutting machine body 1, an edge-finding detector 12, a gripper 2, a transfer device 3, and a controller. The laser cutting machine body 1 comprises a workbench for placing material 11; an edge-finding detector 12 slidably disposed on the periphery of the workbench for detecting the side edges of the material 11 placed on the workbench; a gripper 2 for grasping the material 11; the gripper 2 being disposed on the transfer device 3 and driven by the transfer device 3 to move within a preset range, for grasping the material 11 from a preset position and transferring it to the workbench; the gripper 2, the edge-finding detector 12, and the transfer device 3 are all connected to the controller signal.

[0053] like Figure 1As shown, the laser cutting machine body 1 is used to place and laser cut the material 11. It should be noted that the laser cutting machine body 1 is an existing mature technology and will not be described in detail here. In conjunction with this, an edge-finding detector 12 is provided on the periphery of the workbench of the laser cutting machine body 1 for placing the material 11. The edge-finding detector 12 uses a position sensor or camera that moves along the X and Y directions to detect the position of the material 11, so that edge-finding operations can be performed on the material 11 placed on the workbench. A transfer device 3 is provided, and a gripper 2 is provided at the end of the transfer device 3, so that the material 11 can be grabbed from a specified position to transfer the material 11 to the workbench of the laser cutting machine body 1, and the gripper 2, the transfer device 3 and the edge-finding detector 12 are all operated under the control of the controller.

[0054] Optionally, the transfer device 3 adopts a vehicle body with a walking structure such as a track assembly, wheels, or a track wheel pair.

[0055] Optionally, the transfer device 3 adopts a multi-joint robotic arm, and the transfer device 3 is set at a preset position. Under the coordinated action of each joint, the transfer device 3 can drive the gripper 2 to reciprocate between the specified position and the laser cutting machine body 1, so as to repeatedly grab the material 11 through the gripper 2 that can be opened and closed at the end position of the transfer device 3 and place it on the laser cutting machine body 1.

[0056] Optionally, the transfer device 3 includes a first linear slide 31, a second linear slide 32 and a third linear slide 33, and the second linear slide 32, the first linear slide 31 and the third linear slide 33 are perpendicular to each other; the first linear slide 31 is slidably arranged on the second linear slide 32, the third linear slide 33 is slidably arranged on the first linear slide 31, and the gripper 2 is slidably arranged on the third linear slide 33; the second linear slide 32 is located at the top of the laser cutting machine body 1.

[0057] Specifically, the transfer device 3 uses a rectangular coordinate system robot arm, such as Figure 1 and Figure 4As shown, the first linear slide 31 extends along the X direction, the second linear slide 32 extends along the Y direction, and the third linear slide 33 extends along the Z direction. The first linear slide 31 can slide along the second linear slide 32, and the third linear slide 33 can slide along the first linear slide 31. The gripper 2 is slidably arranged on the third linear slide 33, and the second linear slide 32 is located at the top of the laser cutting machine body 1. When in use, the material 11 is first placed at the specified position, and the transfer device 3 is controlled to drive the gripper 2 to the specified position. The gripper 2 is driven down by the third linear slide 33 to grab the material 11 through the gripper 2. Then, the gripper 2 is guided and driven by the third linear slide 33 to drive the material 11 to rise, and under the guidance and drive of the first linear slide 31 and the second linear slide 32, the material 11 is driven to move above the laser cutting machine body 1 to realize the transfer of the material 11.

[0058] When in use, the fully automatic laser cutting machine is started, and the transfer device 3 is controlled to start by the controller. The transfer device 3 drives the gripper 2 to move to the location of the material 11, and grabs the material 11 under the control of the controller, and then transfers the material 11 to the workbench of the laser cutting machine body 1. Then, the edge-finding detector 12 is started by the controller and driven to move to perform an edge-finding operation on the material 11, that is, to determine the exact position of the material 11 on the workbench of the laser cutting machine body 1. Finally, the laser cutting machine body 1 is started to work to complete the cutting operation of the material 11. With such a setting, the fully automatic laser cutting machine has a high degree of automation, a high efficiency in laser cutting the material 11, and a high positioning accuracy. It can position materials 11 of different shapes, has strong compatibility, and can position a variety of different materials.

[0059] On the basis of the above embodiment, it also includes a loading workbench 4 and a loading sensor 5; the loading workbench 4 is located on the side of the laser cutting machine body 1, and the material 11 can be placed on the loading workbench 4; the detection head of the loading sensor 5 is facing the loading workbench 4 to detect whether the material 11 is placed on the loading workbench 4, and the loading sensor 5 is connected to the controller signal.

[0060] like Figure 1 As shown, the top surface of the loading workbench 4 is used to place and support the material 11 to be processed. It should be noted that there is no restriction on the type of the loading workbench 4, such as a frame structure or a solid seat structure, as long as it can meet the above functions; in conjunction with this, a loading sensor 5, such as a camera or an optical sensor, is provided on the peripheral surface of the loading workbench 4 to detect whether there is material 11 placed on the surface of the loading workbench 4.

[0061] During use, the controller receives the detection signal of the loading sensor 5. When there is material 11 on the loading workbench 4, the controller controls the transfer device 3 to grab the material 11 from the loading workbench 4 and transfer the material 11 to the laser cutting machine body 1 for cutting the material 11; and when it is detected that there is no material 11 on the loading workbench 4, the controller outputs the detection result to remind the operator to load the material to the loading workbench 4.

[0062] On the basis of the above embodiment, the first end and the second end of the loading workbench 4 along the X direction are both provided with a first limit member 6 for limiting the movement of the material 11 along the X direction, and the first end and the second end of the loading workbench 4 along the Y direction are both provided with a second limit member 7 for limiting the movement of the material 11 along the Y direction, and the X direction is perpendicular to the Y direction.

[0063] like Figure 1 、 Figure 3 and Figure 4 As shown, a first limiter 6 is provided at both ends of the upper surface of the loading workbench 4 along the X direction. The first limiter 6 can be a long strip-shaped protrusion structure extending along the Y direction or a cylindrical structure extending along the Z direction. When in use, the material 11 is placed between the first limiters 6 at both ends, and the first limiters 6 at both ends can cooperate to limit the material 11 from moving arbitrarily along the X direction; similarly, a second limiter 7 is provided on both sides of the upper surface of the loading workbench 4 along the Y direction. The second limiter 7 can be a long strip-shaped frame structure extending along the X direction or a cylindrical structure extending along the Z direction. When in use, the material 11 is placed between the second limiters 7 on both sides, and the second limiters 7 on both sides can cooperate to limit the material 11 from moving arbitrarily along the Y direction.

[0064] In some embodiments, as Figure 3 and Figure 4 As shown, the second stopper 7 on one side of the loading platform 4 along the Y direction is an arched frame structure. Two spaced-apart second stoppers 7 are installed on the other side of the loading platform 4 along the Y direction. These second stoppers 7 are strip-shaped stoppers. Furthermore, the height of these strip-shaped stoppers along the Z direction is lower than the height of the arched frame structure along the Z direction. This reduces the weight of the loading platform 4 while enhancing the second stopper 7's ability to limit the position of materials 11 at different heights, helping to prevent the materials 11 from tilting and falling.

[0065] It should be noted that the first limiting member 6 and the second limiting member 7 can be the same or different, the first limiting members 6 located on both sides can be the same or different, and the second limiting members 7 located on both sides can be the same or different.

[0066] Furthermore, the first limit member 6 can be optionally set at different positions of the loading workbench 4 along the X direction, and the second limit member 7 can be optionally set at different positions of the loading workbench 4 along the Y direction. Specifically, the first limit member 6 and the second limit member 7 are installed on the loading workbench 4 in a detachable manner such as snap connection or bolt connection, and a number of first connection parts connected to the same first limit member 6 are provided on the loading workbench 4, and a number of second connection parts connected to the same second limit member 7 are provided on the loading workbench 4. The first connection part and the second connection part can adopt threaded holes or snap-on terminals, etc., and the first limit member 6 and the second limit member 7 can be set according to materials 11 of different sizes or shapes. With this arrangement, while ensuring the positioning accuracy of the material 11, the compatibility of the loading workbench 4 can be effectively improved.

[0067] With such arrangement, the first limiting members 6 and the second limiting members 7 located at the periphery can more accurately position the material 11 placed on the loading workbench 4 .

[0068] Based on the above embodiment, the loading sensor 5 is installed on the loading workbench 4, and the top surface of the loading workbench 4 has a detection window 41. The detection head of the loading sensor 5 extends into the detection window 41, and the detection head of the loading sensor 5 faces the top surface of the loading workbench 4.

[0069] Optional, such as Figure 1 、 Figure 3 and Figure 4 As shown, the loading workbench 4 adopts a frame structure, and the top of the loading workbench 4 is composed of several staggered beam structures, and space is left between adjacent beam structures as a detection window 41; optionally, the loading workbench 4 adopts a hollow box structure, and a through hole is opened on the top plate of the box structure as the detection window 41, and the loading sensor 5 is installed on the loading workbench 4 through a rod structure or a base structure, and the detection head of the loading sensor 5 extends into the detection window 41 and faces upward to detect the material 11 placed on the loading workbench 4. It should be noted that the loading workbench 4 and the detection window 41 are not limited to the above-mentioned example types, as long as the above-mentioned functions can be met.

[0070] In conjunction with the embodiment in which the first limiting member 6 and the second limiting member 7 are provided, the detection window 41 is provided between the first limiting members 6 on both sides and between the second limiting members 7 on both sides.

[0071] On the basis of the above embodiment, the number of the second linear slide rails 32 is two, and the two second linear slide rails 32 are arranged in parallel on both sides of the laser cutting machine body 1, and the first linear slide rail 31 is slidably arranged on the two second linear slide rails 32 at the same time, such as Figure 1 and Figure 2As shown, a second linear slide rail 32 is provided on both the left and right sides of the laser cutting machine body 1 . With such a configuration, the first linear slide rail 31 moves more stably under the guidance of the two second linear slide rails 32 .

[0072] Based on the above embodiment, a support leg 8 is provided at the bottom of the second linear slide rail 32, and corresponding support legs 8 are provided at both ends of the two second linear slide rails 32; the ends of the two second linear slide rails 32 on the same side can be connected by a reinforcement beam 9.

[0073] like Figure 1 and Figure 2 As shown, the two second linear slide rails 32 can be relatively stably set on the ground through the four support legs 8 located below them at intervals, and the height of the support legs 8 is greater than the height of the laser cutting machine body 1, so that the second linear slide rails 32 are higher than the laser cutting machine body 1, and the ends of the two second linear slide rails 32 on one side along the Y direction are connected by a reinforcing beam 9, and the ends of the two second linear slide rails 32 on the other side along the Y direction can be connected by another reinforcing beam 9. With this arrangement, the structure of the transfer device 3 is relatively simple and the operation stability is relatively high.

[0074] Preferably, the four supporting legs 8 are located outside the adjacently arranged laser cutting machine body 1 and the loading workbench 4 to ensure that the gripper 2 can reciprocate between the loading workbench 4 and the laser cutting machine body 1 .

[0075] Based on the above embodiment, the gripper 2 further includes a support member 21, a suction cup 22, a vacuum switch 23, an on-off valve 24, and a vacuum generator 25. The transfer device 3 is connected to the top of the support member 21, and a connector can be provided on the top of the support member 21 to connect the transfer device 3. The suction cup 22 is mounted on the bottom of the support member 21 to suck up the material 11. The vacuum generator 25 is electrically connected to the suction cup 22. The vacuum switch 23 and the on-off valve 24 are both mounted on the support member 21, and the vacuum generator 25 and the suction cup 22 are electrically connected via the vacuum switch 23 and the on-off valve 24. The vacuum switch 23 and the on-off valve 24 are both connected to the controller signal.

[0076] like Figure 1 and Figure 5 As shown, the support member 21 can adopt a frame structure or a flat plate structure, etc., which is used to install and support components such as a suction cup 22, a vacuum switch 23, a switch valve 24 and a vacuum generator 25. The transfer device 3 is connected to the top of the support member 21, and the suction cup 22 is installed on the lower surface of the support member 21, and the opening of the suction cup 22 faces downward. Then, after driving the gripper 2 to descend to a preset height, the suction cup 22 can be brought into contact with the material 11. Optionally, a suction cup 22 is set in the middle position of the support member 21. Optionally, a plurality of suction cups 22 are evenly set along a rectangular path around the support member 21.

[0077] In coordination, the vacuum generator 25 is connected to the suction cup 22 through a pipeline, and a vacuum switch 23 and a switch valve 24 are set in the pipeline system between the vacuum generator 25 and the suction cup 22. When in use, after driving the gripper 2 to move to the specified position, the gripper 2 is driven down by the third linear slide 33 until the suction cup 22 contacts the material 11, and then the switch valve 24 is controlled to open and the vacuum generator 25 is started by the controller to create a negative pressure environment between the suction cup 22 and the material 11. At the same time, the negative pressure value between the suction cup 22 and the material 11 is detected by the vacuum switch 23. After the negative pressure value reaches the standard, the switch valve 24 is controlled to close and the vacuum generator 25 is stopped by the controller, and then the gripper 2 is driven to rise by the third linear slide 33 to suck up the material 11.

[0078] Based on the above embodiment, a micro switch 26 is further installed at the bottom of the support 21; the distance between the suction cup 22 and the bottom end of the support 21 is greater than the distance between the micro switch 26 and the bottom end of the support 21; the micro switch 26 is connected to the controller signal.

[0079] The micro switch 26 and the suction cup 22 are both installed below the support 21. When in use, the controller controls the transfer device 3 to drive the gripper 2 to descend along the Z direction. Since the position of the micro switch 26 is higher than that of the suction cup 22, when driving the support 21 and the micro switch 26 and suction cup 22 thereon to descend synchronously, the suction cup 22 first contacts the material 11. Then, under the continuous downward pressure of the transfer device 3, the suction cup 22 will first produce a certain compression until the micro switch 26 comes into contact with the material 11, so that the transfer device 3 is controlled by the controller to stop descending, and the switch valve 24 and the vacuum generator 25 are started to generate a vacuum between the suction cup 22 and the material 11. With such an arrangement, under the control of the micro switch 26 and the controller, since the vacuum generator 25 is started only under the premise that over-pressure contact has been generated between the suction cup 22 and the material 11, the vacuum switch 23 can quickly generate a signal that the negative pressure value meets the standard, which is beneficial to improve the transfer efficiency and reduce energy loss.

[0080] Furthermore, the support member 21 and the loading workbench 4 both adopt a frame structure, which effectively reduces the weight of the fully automatic laser cutting machine.

[0081] On the basis of the above embodiment, the support member 21 is further installed with a vacuum filter 27 . The inlet of the vacuum filter 27 is connected to the outlet of the vacuum generator 25 , and the outlet of the vacuum filter 27 is connected to the suction cup 22 .

[0082] like Figure 5As shown, a vacuum filter 27 is further provided in the pipeline system between the vacuum generator 25 and the suction cup 22 , so the negative pressure airflow generated by the vacuum generator 25 will first be filtered by the vacuum filter 27 and then generate negative pressure in the suction cup 22 .

[0083] In some possible embodiments, the support member 21 includes a connecting beam 213, a first frame 211 and a second frame 212. The first frame 211 and the second frame 212 are arranged parallel to each other and are fixedly connected as a whole by a plurality of connecting beams 213; the width of the first frame 211 along the Y direction is equal to the width of the second frame 212 along the Y direction, and the length of the first frame 211 along the X direction is less than the length of the second frame 212 along the X direction; the end beams of the first frame 211 along the X direction are parallel to the end beams of the second frame 212 along the X direction, and the end beams of the second frame 212 along the Y direction are parallel to the end beams of the second frame 212 along the Y direction; the end of the transfer device 3 is connected to the top of the first frame 211, and the suction cup 22, vacuum switch 23, switch valve 24, vacuum generator 25 and micro switch 26 are all installed on the second frame 212.

[0084] like Figure 5 As shown, the first frame 211 and the second frame 212 are both rectangular, and the two are arranged in parallel and connected as a whole through a connecting beam 213; and the end beams at both ends of the first frame 211 along the Y direction are parallel to the end beams at both ends of the second frame 212 along the Y direction, and the end beams at both ends of the first frame 211 along the X direction are parallel to the end beams at both ends of the second frame 212 along the X direction. The width of the first frame 211 along the Y direction is equal to the width of the second frame 212 along the Y direction, and the length of the first frame 211 along the X direction is less than the length of the second frame 212 along the X direction. One end of the connecting beam 213 is connected to the end beams around the first frame 211, and the other end of the connecting beam 213 is connected to the end beams at both ends of the second frame 212 along the Y direction, and is connected to the middle position of the second frame 212 along the X direction, so that the support member 21 is a T-shaped structure.

[0085] coordinated, combined Figure 1 and Figure 5 As shown, the end of the transfer device 3 is connected to the top of the first frame 211, and the vacuum switch 23, the switch valve 24, the vacuum generator 25, the suction cup 22 and the micro switch 26 are all installed on the second frame 212 located on the lower side.

[0086] With such a configuration, the weight of the support member 21 is relatively low, which is beneficial for reducing the load of the transfer device 3 and making it easier to take the material 11 from the loading workbench 4 .

[0087] Furthermore, the connecting beam 213 is perpendicular to the first frame 211 and the second frame 212, and the connecting beam 213 and the first frame 211, and the connecting beam 213 and the second frame 212 are connected by corner joints, which can be made of T-shaped angle steel or right-angle steel.

[0088] Going further, Figure 5 As shown, the suction cup 22 and the micro switch 26 are located on the side of the second frame 212 away from the first frame 211 , and the vacuum switch 23 , the switch valve 24 , the vacuum generator 25 and the vacuum filter 27 are all located on the side of the second frame 212 close to the first frame 211 .

[0089] On the basis of the above embodiment, a dust removal filter 10 is further included. The inlet of the dust removal filter 10 is connected to the exhaust port of the laser cutting machine body 1 to remove dust from the workbench. While the fully automatic laser cutting machine is performing laser cutting, the dust removal filter 10 can absorb metal slag and dust on the workbench to ensure the cleanliness of the working environment of the fully automatic cutting machine.

[0090] Preferably, the dust removal filter 10 is connected to the controller signal, so that the dust removal filter 10 can be started by controlling the controller before laser cutting.

[0091] It should be noted that there is no restriction on the type of controller, such as a PLC programmable logic controller or a CPU central processing unit, as long as the above control functions can be achieved.
