It should be understood that the specific examples described herein are only used to explain the present disclosure and do not limit the present disclosure.

It is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore the above terms cannot be understood as limiting the present application.

[0057] The present application will be further described in detail below in combination with the drawings, see for exampleFigures 1 to 8 illustrate.

[0058] This application provides a laser cutting device 1, such as... Figure 1 As shown, it includes a worktable 11, a material placement mechanism 12, a loading mechanism 13, a laser mechanism 14, and a unloading mechanism 15. The material placement mechanism 12, loading mechanism 13, laser mechanism 14, and unloading mechanism 15 are arranged on the worktable 11. The function of the material placement mechanism 12 is to guide the workpiece 2 from the loading station to the laser cutting station. The loading mechanism 13 is used to transfer the unprocessed workpiece 2 to the material placement mechanism 12. The laser mechanism 14 is used to cut the workpiece 2 into a specific shape. In this application, the laser mechanism 14 can cut the rectangular magnetic tile workpiece into a parallelogram. The unloading mechanism 15 unloads the workpiece 2 that has been cut on the material placement mechanism 12. In this application, the material placement mechanism 12 can temporarily store at least two workpieces 2 at the same time and can automatically push the workpiece 2 from the loading station to the laser cutting station to facilitate the laser mechanism 14 to cut the workpiece 2.

[0059] like Figures 1 to 3 As shown, the material placement mechanism 12 is equipped with a loading station and a laser cutting station, which are located at opposite ends of the material placement mechanism 12. The loading mechanism 13 is located on one side of the loading station, while the laser mechanism 14 and the unloading mechanism 15 are located on the other side of the laser cutting station. In this application, with the cooperation of the loading mechanism 13 and the material placement mechanism 12, after the laser mechanism 14 processes one workpiece 2 on the material placement mechanism 12, the material placement mechanism 12 can push at least one remaining workpiece 2 to the laser processing station. This provides a buffer time for the loading mechanism 13, allowing it to move back and forth between the storage area and the material placement mechanism 12 during this buffer time. Before all workpieces 2 on the material placement assembly 121 are processed, the material placement mechanism 12 is loaded again, enabling the material placement mechanism 12 to continuously guide workpieces 2 to the laser cutting station. The laser mechanism 14 can also continuously process workpieces 2, greatly reducing efficiency problems caused by long loading intervals, thereby significantly improving the overall working efficiency of the laser cutting device 1.

[0060] It should be noted that in this application, the displacement parallel to the workpiece 2 moving from the loading station to the laser cutting station on the material placement mechanism 12 is taken as the X-axis, the direction perpendicular to the X-axis on the worktable 11 is taken as the Y-axis, and the direction perpendicular to the worktable 11 is taken as the Z-axis. The X-axis, Y-axis, and Z-axis share a common reference coordinate system to facilitate the description of the relationship between the various mechanisms in this application.

[0061] Specifically, such as Figures 1 to 5As shown, the material placement mechanism 12 includes a material placement component 121 and a material pushing component 122. The material placement component 121 has a placement space arranged along the X-axis direction, which can simultaneously hold at least two workpieces 2. The material pushing component 122 is used to push the workpieces 2 on the material placement component 121 toward the laser processing station. That is, the material pushing component 122 can push the workpieces 2 along the X-axis direction so that the material placement mechanism can automatically transfer the workpieces 2 to the laser processing station.

[0062] Among them, such as Figures 4 to 5 As shown, the material placement assembly 121 includes a material placement platform 1211 and a pressing component 1212. Two material placement platforms 1211 are provided, and the two material placement platforms 1211 are arranged at intervals to form a material placement space for horizontally limiting the workpiece 2. The pressing component 1212 is connected to the material placement platform 1211 and is set on the laser processing station, which can press the workpiece 2 located on the laser station and limit the workpiece 2 in the Z-axis direction. In conjunction with the material placement space, the workpiece 2 is horizontally limited, so that the workpiece 2 can be limited in both the horizontal and vertical planes, so that the material can be kept stable during laser cutting and the processing yield can be improved.

[0063] Furthermore, the material placement platform 1211 is described in more detail; such as... Figures 4 to 5 , Figures 7 to 8 As shown, the material placement table 1211 is provided with a first limiting part 1215 and a second limiting part 1216. The first limiting part 1215 is a protrusion that extends and protrudes along the Y-axis towards the other material placement table 1211. That is, the first limiting part 1215 is connected to the side end of the second limiting part 1216 along the Y-axis. The upper end surface of the first limiting part 1215 is opposite to the bottom of the workpiece 2. In the Z-axis direction, the upper end surface of the first limiting part 1215 is lower than the upper end surface of the second limiting part 1216. The second limiting part 1216 forms a limiting position on the workpiece 2 along the Z-axis. The sides of workpiece 2 are opposite each other; when workpiece 2 is placed on the storage space, the bottom of workpiece 2 is in contact with the upper surface of the first limiting part 1215, and the second limiting part 1216 can limit the outer side of workpiece 2. The two second limiting parts 1216 together form a limit on workpiece 2 in the horizontal direction, and the two first limiting parts 1215 together form a limit on workpiece 2 in the vertical direction. The first limiting part 1215, after cooperating with the pressure member 1212, can completely limit workpiece 2 in the vertical direction, so that workpiece 2 is more stable during laser cutting.

[0064] Among them, such as Figure 5As shown, the material placing assembly 121 further comprises a material placing adjusting member 1214 connected with the at least one material placing table 1211, the material placing adjusting member 1214 is arranged parallel to the Y-axis direction, the material placing adjusting member 1214 comprises a guide rail and a sliding block, the guide rail is arranged on the workbench 11 along the Y-axis direction, the lower end of the sliding block is in sliding connection with the guide rail, and the upper end of the sliding block is fixedly connected with the material placing table 1211; the sliding block can drive the material placing table 1211 to slide along the guide rail, so as to adjust the size of the material placing space in the Y-axis direction, so that the material placing assembly 121 can place workpieces 2 of different sizes, and the application range of the laser cutting device 1 is improved. The material placing adjusting member 1214 can drive the material placing table 1211 to move by electricity or by gas, or the material placing table 1211 can be manually driven to move. In addition, a limiting member can also be arranged on the guide rail to fix the material placing table 1211 after displacement, so as to ensure the stability of the material placing table 1211.

[0065] It should be noted that, as Figure 8 shown, in the Y-axis direction, the horizontal distance between the two first limiting portions 1215 is L1, the horizontal distance between the two second limiting portions 1216 is L2, and the horizontal width of the workpiece 2 is L3, L2≥L3>L1, so that the material placing space formed by the first limiting portion 1215 and the second limiting portion 1216 can accommodate the workpiece 2.

[0066] On the basis of the above embodiment, the second limiting portion 1216 is further expanded; as Figure 7 、 Figure 8 shown, the second limiting portion 1216 comprises a material placing portion 1216.1, a guide portion 1216.2 and a material fixing portion 1216.3 connected in sequence along the X-axis, the material placing portion 1216.1 is close to the feeding mechanism 13, the material fixing portion 1216.3 is close to the laser mechanism 14, the guide portion 1216.2 is located between the material placing portion 1216.1 and the material fixing portion 1216.3, one end of the guide portion 1216.2 is connected with the material placing portion 1216.1, and the other end is connected with the material fixing portion 1216.3, wherein the material placing portion 1216.1 and the material fixing portion 1216.3 are arranged parallel to the X-axis, and the guide portion 1216.2 is inclined to the X-axis. Further, as Figure 8As shown, the distance between the material placement parts 1216.1 on the two material placement platforms 1211 is L21, and the distance between the material holding parts 1216.3 on the two material placement platforms 1211 is L23, where L21>L23=L2. That is, the material placement parts 1216.1 on the two material placement platforms 1211 form a space larger than the workpiece 2. When the feeding mechanism 13 places the workpiece 2 on the material placement part 1216.1, it does not need to be controlled too precisely, which increases the allowable error range of the feeding mechanism 13, improves fault tolerance, and speeds up the placement rate of the workpiece 2. The guide part 1216.2 can reduce the resistance of the workpiece 2 moving from the material placement part 1216.1 to the material holding part 1216.3, and guide the workpiece 2 to smoothly enter the material holding part 1216.3.

[0067] Furthermore, such as Figure 5 As shown, the material placement assembly 121 also includes a pressure adjustment member 1213, which is disposed on the outside of the material placement table 1211. The outer side of the pressure member 1212 is connected to the pressure adjustment member 1213. The other end of the pressure member 1212 extends toward the material placement space and is at least partially located within the material placement space. The pressure member 1212 is generally a rectangular arch structure. The portion of the pressure member 1212 located within the material placement space protrudes downward to fall above the first limiting part 1215 and cooperate with the first limiting part 1215 to press the workpiece 2. In this embodiment, the pressure adjustment member 1213 can drive the pressure member 1212 to move in the vertical direction to adjust the setting position of the pressure member 1212 in the Z-axis direction, so that the pressure member 1212 can press the workpiece 2 with different thicknesses.

[0068] In another optional embodiment at the other end of this application, such as Figure 2 , Figure 5 As shown, the feeding assembly 122 includes a feeding plate 1221 and a feeding displacement adjusting member 1222. The feeding displacement adjusting member 1222 is located on the side of the feeding assembly 121 away from the feeding mechanism 13. The feeding displacement adjusting members 1222 are spaced apart on the side of the feeding assembly 121 and are arranged parallel to the X-axis. The feeding plate 1221 is basically inverted L-shaped. One end of the feeding plate 1221 is slidably connected to the feeding displacement adjusting member 1222, and the other end of the feeding plate 1221... One end extends toward the material placement assembly 121 and at least partially extends downward along the Z-axis within the material placement space, and the bottom of the pusher plate 1221 is lower than the bottom of the workpiece 2 in the Z-axis direction; the pusher displacement adjustment component 1222 is used to drive the pusher plate 1221 to move along the X-axis. When the pusher plate 1221 moves, the pusher plate 1221 pushes the workpiece 2 to move along the X-axis, so that the workpiece 2 can move from the loading station to the laser cutting station, thereby realizing the automatic loading of the laser mechanism 14 by the pusher assembly 122.

[0069] It should be noted that the length of the pushing displacement adjusting piece 1222 is greater than the length of the placing table 1211, and the two ends of the pushing displacement adjusting piece 1222 exceed the two ends of the placing table 1211, so that the pushing plate 1221 can fully push the workpiece 2. At the same time, in the embodiment, a stroke sensor is arranged on the pushing displacement adjusting piece 1222, so that the pushing plate 1221 can move according to the set displacement, and the pushing accuracy of the workpiece 2 is ensured. In addition, in the embodiment, the pushing displacement adjusting piece 1222 adopts a linear motor module or other devices with the same effect.

[0070] On the basis of any of the above embodiments, the feeding mechanism 13 of the present application is further described; in an embodiment, the feeding mechanism 13 comprises a feeding suction disc 131 and a feeding adjusting assembly, the upper end of the feeding suction disc 131 is connected with the feeding adjusting assembly, and the feeding adjusting assembly is used to drive the feeding suction disc 131 to reciprocate between the storage area and the feeding station of the placing mechanism 12; the feeding suction disc 131 is provided with suction holes, and the feeding suction disc 131 can generate suction force to suck the workpiece 2.

[0071] Specifically, as shown in Figure 2 , Figure 6 The feeding adjusting assembly comprises a feeding horizontal displacement adjusting piece 133 and a feeding vertical displacement adjusting piece 132, the feeding horizontal displacement adjusting piece 133 is arranged along the Y axis, one end of the feeding horizontal displacement adjusting piece 133 corresponds to the storage area, and the other end corresponds to the feeding station of the placing assembly 121, and the feeding horizontal displacement adjusting piece 133 can drive the feeding suction disc 131 to reciprocate between the storage area and the feeding station; the feeding vertical displacement adjusting piece 132 is used to adjust the displacement of the feeding suction disc 131 in the vertical direction (Z axis direction), so that the storage condition of the workpiece 2 of different heights can be adapted, and the workpiece 2 can be accurately sucked. For example, when the stacking height of the workpiece 2 in the storage area is reduced, the feeding vertical displacement adjusting piece 132 can ensure that the feeding suction disc 131 is lowered to an appropriate height to suck the workpiece 2, and then the feeding horizontal displacement adjusting piece 133 moves the feeding suction disc 131 with the workpiece 2 to above the feeding station of the placing mechanism 12, and the feeding vertical displacement adjusting piece 132 adjusts the height again to place the workpiece 2 on the feeding station.

[0072] In the embodiment, one end of the feeding vertical displacement adjusting piece 132 is connected with the feeding suction disc 131, and the other end is connected with the feeding horizontal displacement adjusting piece 133; or one end of the feeding horizontal displacement adjusting piece 133 is connected with the feeding suction disc 131, and the other end is connected with the feeding vertical displacement adjusting piece 132. That is, the feeding horizontal displacement adjusting piece 133 can be arranged above the vertical displacement adjusting piece, or arranged below the vertical displacement adjusting piece, and the specific arrangement position can be selected according to the actual use requirement.

[0073] On the basis of any of the above embodiments, the laser mechanism 14 of the present application is further described; the laser mechanism 14 comprises a laser head 141 and a laser adjusting assembly, the laser head 141 is connected to the end of the laser adjusting assembly close to the material placing mechanism 12, the laser head 141 is located above the workpiece 2, which is used to generate a laser beam to perform laser cutting on the workpiece 2; and the laser adjusting assembly is arranged on the workbench 11, which is used to adjust the position of the head, so that the laser head 141 can be adjusted to the precise position to process the workpiece 2.

[0074] Specifically, as shown in Figure 2 、 Figure 3 , the laser adjusting assembly comprises a first laser displacement adjusting member 142, a second laser displacement adjusting member 143 and a third laser displacement adjusting member 144, the first laser displacement adjusting member 142 is used to drive the laser head 141 to displace parallel to the first direction, the second laser displacement adjusting member 143 is used to drive the laser head 141 to displace parallel to the second direction, and the third laser displacement adjusting member 144 is used to drive the laser head 141 to displace parallel to the third direction; wherein the first direction is parallel to the X axis, the second direction is parallel to the Y axis, and the third direction is parallel to the Z axis; under the joint action of the three laser displacement adjusting members, the position of the laser head 141 can be corrected to ensure cutting accuracy. The laser adjusting assembly can be in electric or pneumatic mode.

[0075] On the basis of any of the above embodiments, the unloading mechanism 15 of the present application is further described; as shown in Figure 1 、 Figure 4 , the unloading mechanism 15 comprises a guide plate 151 and a conveying belt 152, the conveying belt 152 is arranged along the Y axis, the conveying belt 152 is arranged at one end of the material placing assembly 121 close to the laser mechanism 14, and in the Z axis direction, the conveying belt 152 is located below the discharge port of the material placing assembly 121; the guide plate 151 is arranged at the discharge port of the material placing assembly 121, the guide plate 151 is arranged obliquely to the vertical direction, the upper end of the guide plate 151 corresponds to the discharge port of the material placing assembly 121, and the lower end corresponds to the conveying belt 152, the guide plate 151 is used to guide the workpiece 2 from the material placing assembly 121 to the conveying belt 152; the conveying belt 152 is used to convey the processed workpiece 2 to the unloading area, realize automatic unloading, and improve the automation degree of the laser cutting device 1.

[0076] In addition, in order to further improve the automation degree of the whole laser cutting device 1, an intelligent monitoring system can be considered for the device. The intelligent monitoring system can monitor the running state of each mechanism in real time, such as the feeding frequency of the feeding mechanism 13, the temporary storage condition of the workpiece 2 of the material placing mechanism 12, the cutting progress of the laser mechanism 14, and the unloading speed of the unloading mechanism 15.

[0077] When the intelligent monitoring system detects that the feeding frequency of the feeding mechanism 13 is abnormally reduced, it may be that the supply of workpieces 2 in the storage area is insufficient or that the feeding suction cup 131 is malfunctioning. At this time, the system can issue an alarm signal to remind the operator to replenish the workpieces 2 in time or to check whether the suction force of the feeding suction cup 131 is normal.

[0078] For the feeding mechanism 12, if it is found that the number of workpieces 2 temporarily stored therein has not changed for a long time, it may be that the pushing assembly 122 is blocked or that the feeding mechanism 13 fails to feed in time. The intelligent monitoring system can locate the specific problem and provide a corresponding solution, such as cleaning the pushing assembly 122 or adjusting the feeding rhythm of the feeding mechanism 13.

[0079] In terms of the laser mechanism 14, the monitoring system can accurately measure the cutting trajectory of the laser head 141. If it is found that the cutting trajectory deviates from the preset trajectory, in addition to automatic correction through the laser adjusting assembly, the deviation data can also be recorded for regular and accurate maintenance of the laser mechanism 14.

[0080] The speed of the conveyor belt 152 of the discharging mechanism 15 is also within the monitoring range.
