[0002] Laser engraving equipment is commonly used for precision machining of workpieces. It generates a laser through a laser engraving mechanism to process the workpiece fixed on a clamping mechanism. In existing technology, the laser generated by the laser engraving mechanism can only cover a portion of the workpiece. When the area to be processed on the workpiece is large, the laser engraving equipment cannot meet the processing requirements. Furthermore, if there is a deviation in the position of the workpiece fixed on the clamping mechanism, it will lead to a large processing error. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a laser engraving device that can adapt to processing workpieces of different processing area sizes and improve processing accuracy.

[0004] This utility model provides a laser engraving device, which includes a laser engraving mechanism, a clamping mechanism, and a detection mechanism. The laser engraving mechanism includes multiple laser engraving components, whose laser emission directions are tilted relative to each other to simultaneously process a workpiece at multiple angles. The clamping mechanism is movably connected to the laser engraving mechanism, used to mount the workpiece, and can drive the workpiece to move relative to the laser engraving components. The detection mechanism is connected to the laser engraving mechanism and used for visual positioning of the workpiece. The detection mechanism is electrically connected to the clamping mechanism, and the detection mechanism and clamping mechanism can collaboratively control the position of the workpiece relative to the laser engraving mechanism.

[0005] The laser engraving equipment provided by this utility model has at least the following beneficial effects:

[0006] The laser engraving component generates laser light to process the workpiece, while the clamping mechanism moves the workpiece relative to the laser engraving component, enabling the laser engraving equipment to adapt to workpieces of varying processing area sizes. The detection mechanism provides visual positioning of the workpiece, and the detection and clamping mechanisms work together to control the workpiece's position relative to the laser engraving component, improving the processing accuracy of the laser engraving equipment. Multiple laser engraving components generate lasers with mutually tilted emission directions, allowing for simultaneous processing of a single workpiece from multiple angles, thus increasing processing efficiency.

[0007] In one embodiment of this implementation, the clamping mechanism is used to drive the workpiece to move in a horizontal plane, two laser engraving components are spaced apart, the detection mechanism is disposed between the two laser engraving components, the line of sight of the detection mechanism is perpendicular to the horizontal plane, and the laser emission directions generated by the two laser engraving components are at the same angle to the line of sight of the detection mechanism.

[0008] In one embodiment of this implementation, the laser engraving equipment further includes a feeding mechanism and a first transfer mechanism. Both the feeding mechanism and the first transfer mechanism are connected to the laser engraving mechanism. The feeding mechanism is used to store stacked trays, on which multiple workpieces are carried. The first transfer mechanism is used to move the trays to the clamping mechanism. The laser engraving assembly is used to process the workpieces on the trays.

[0009] In one embodiment of this implementation, the laser engraving equipment further includes a second transfer mechanism connected to the laser engraving mechanism, and the detection mechanism electrically connected to the second transfer mechanism. The clamping mechanism has a receiving groove for fixing the workpiece. The detection mechanism is also used to perform shape detection on the workpiece on the tray. The clamping mechanism drives the tray to move to the bottom side of the second transfer mechanism so that the second transfer mechanism can move the workpiece that does not meet the shape requirements to the receiving groove.

[0010] In one embodiment of this implementation, the clamping mechanism has a plurality of receiving slots.

[0011] In one embodiment of this implementation, the laser engraving equipment further includes a feeding mechanism connected to the laser engraving mechanism. The feeding mechanism is used to store the stacked material trays, and the first transfer mechanism is also used to move the material trays on the clamping mechanism to the feeding mechanism.

[0012] In one embodiment of this implementation, the first transfer mechanism includes a motion component and two connecting components. The two connecting components are mounted on the motion component. The motion component is used to drive the connecting components to move. The connecting components are used to connect with the material tray. When one of the connecting components drives the material tray on the loading mechanism to move toward the clamping mechanism, the other connecting component drives the material tray on the clamping mechanism to move toward the unloading mechanism.

[0013] In one embodiment of this implementation, the feeding mechanism includes a feeding bin and a discharging component. The feeding bin is used to store the material tray and has an opening at the top. The discharging component is connected to the feeding bin and is used to drive the material tray in the feeding bin to move toward the opening at the top of the feeding bin. The first transfer mechanism can remove the material tray from the feeding bin through the opening at the top of the feeding bin.

[0014] In one embodiment of this implementation, the feeding mechanism is provided with a feeding bin and a return component. The return component is connected to the feeding bin.

[0034] Please see Figure 1 , Figure 2 , Figure 3 and Figure 6 , Figure 1 This is a three-dimensional structural schematic diagram of a laser engraving device 100 according to one embodiment of the present utility model; Figure 2 yes Figure 1 An enlarged schematic diagram of some of the structures shown; Figure 3 yes Figure 1 A schematic diagram of the structure of the laser engraving mechanism 10, the detection mechanism 30, and the second transfer mechanism 60; Figure 6 yes Figure 1 A schematic diagram of the clamping mechanism 20 is provided. This utility model provides a laser engraving device 100, which includes a laser engraving mechanism 10, a clamping mechanism 20, and a detection mechanism 30. The laser engraving mechanism 10 includes multiple laser engraving components 11, whose laser emission directions are inclined relative to each other to simultaneously process a workpiece 200 at multiple angles. The clamping mechanism 20 is movably connected to the laser engraving mechanism 10, and is used to mount the workpiece 200 and move the workpiece 200 relative to the laser engraving components 11. The detection mechanism 30 is connected to the laser engraving mechanism 10 and is used for visual positioning of the workpiece 200. The detection mechanism 30 is electrically connected to the clamping mechanism 20, and the detection mechanism 30 and the clamping mechanism 20 can collaboratively control the position of the workpiece 200 relative to the laser engraving mechanism 10.

[0035] Please refer to the following for details. Figure 4 and Figure 5 , Figure 4 yes Figure 3 A schematic diagram of the structure of the laser engraving mechanism 10, the detection mechanism 30, and the second transfer mechanism 60 from another perspective; Figure 5 yes Figure 4The diagram shows an enlarged view of a portion of the structure. Two laser engraving components 11 are provided, tilted relative to each other. The tilt angle of the two laser engraving components 11 is set according to the area and position of the processing area of ​​the workpiece 200. The clamping mechanism 20 includes a carrier 22, an X-axis linear driver 23, and a Y-axis linear driver 24. The driving direction of the X-axis linear driver 23 is along the X direction at 40°, and the driving direction of the Y-axis linear driver 24 is along the Y direction at 50°. The stator of the X-axis linear driver 23 is fixed relative to the laser engraving component 11. The stator of the Y-axis linear driver 24 is mounted on the mover of the X-axis linear driver 23. The carrier 22 is mounted on the mover of the Y-axis linear driver 24 and is used to fix the workpiece 200. The detection mechanism 30 includes a visual positioning camera, which is fixed relative to the laser engraving component 11.

[0036] Understandably, tilting the two laser engraving components 11 relative to each other allows their laser emission directions to be tilted, enabling the lasers generated by the two components to irradiate different processing areas on the same workpiece 200. This allows the two components to simultaneously process a single workpiece 200 from multiple angles, improving efficiency. The X-axis linear driver 23 and Y-axis linear driver 24 can move the workpiece 200 relative to the laser engraving components 11, ensuring that the lasers generated by the components completely scan the processing areas on the workpiece 200. The vision positioning camera is fixed relative to the laser engraving components 11, allowing it to more accurately determine the position of the workpiece 200 relative to the components.

[0037] It should be noted that before the laser engraving equipment 100 processes the workpiece 200, the detection mechanism 30 first determines the position of the workpiece 200 relative to the laser engraving component 11. Then, the detection mechanism 30 sends the position information of the workpiece 200 to the clamping mechanism 20. According to the received position information, the clamping mechanism 20 drives the workpiece 200 to move so that the laser energy generated by the laser engraving component 11 can irradiate the preset starting point in the processing area of ​​the workpiece 200. During the processing of the workpiece 200 by the laser engraving equipment 100, the clamping mechanism 20 drives the workpiece 200 to move so that the laser energy can sweep across the entire processing area from the preset starting point in the processing area of ​​the workpiece 200.

[0038] The laser engraving device 100 of this invention includes a laser engraving component 11 that generates laser light to process a workpiece 200. A clamping mechanism 20 moves the workpiece 200 relative to the laser engraving component 11, enabling the laser engraving device 100 to adapt to processing workpieces 200 with different processing area sizes. A detection mechanism 30 performs visual positioning of the workpiece 200. The detection mechanism 30 and the clamping mechanism 20 can work together to control the position of the workpiece 200 relative to the laser engraving mechanism 100, improving the processing accuracy of the workpiece 200. Multiple laser engraving components 11 generate lasers with mutually tilted emission directions, allowing simultaneous processing of a workpiece 200 from multiple angles, thus improving the processing efficiency of the workpiece 200.

[0039] In one embodiment of this implementation, please refer to Figure 1 , Figures 2 to 6 The clamping mechanism 20 is used to drive the workpiece 200 to move in the horizontal plane. Two laser engraving components 11 are arranged at intervals. The detection mechanism 30 is arranged between the two laser engraving components 11. The line of sight 31 of the detection mechanism 30 is perpendicular to the horizontal plane. The laser emission directions generated by the two laser engraving components 11 are at the same angle as the line of sight 31 of the detection mechanism 30.

[0040] Specifically, the laser beam is emitted from the laser engraving component 11 along the light ray 111 and irradiates the workpiece 200. The line of sight 31 forms the angle bisector of the angle formed by the two light rays 111.

[0041] Understandably, the laser emission directions generated by the two laser engraving components 11 are at the same angle to the line of sight 31 of the detection mechanism 30. This ensures that the laser beams emitted by the two laser engraving components 11 are symmetrically distributed on the workpiece 200 with the detection mechanism 30 as the center, which is beneficial for improving the positioning effect and reducing design difficulty. Since the workpiece 200 can move in the horizontal plane, and the line of sight 31 of the detection mechanism 30 is perpendicular to the horizontal plane, this also helps improve the positioning effect of the detection mechanism 30 on the workpiece 200.

[0042] In one embodiment of this implementation, please refer to Figure 1 , Figure 2 , Figure 7 and Figure 8 , Figure 7 yes Figure 1 A schematic diagram of the feeding mechanism 40; Figure 8 yes Figure 1A schematic diagram of the structure of the first transfer mechanism 50 is shown. The laser engraving equipment 100 also includes a feeding mechanism 40 and a first transfer mechanism 50. Both the feeding mechanism 40 and the first transfer mechanism 50 are connected to the laser engraving mechanism 10. The feeding mechanism 40 is used to store stacked material trays 300, on which multiple workpieces 200 are carried. The first transfer mechanism 50 is used to move the material trays 300 to the clamping mechanism 20. The laser engraving assembly 11 is used to process the workpieces 200 on the material trays 300.

[0043] Specifically, multiple workpieces 200 are arranged at intervals on a tray 300, and the trays 300 are stacked vertically on a loading mechanism 40. The loading mechanism 40 is located on one side of the clamping mechanism 20 along the Y direction 500. The first transfer mechanism 50 can move the trays 300 from the loading mechanism 40 to the clamping mechanism 20 along the Y direction 500. The laser engraving assembly 11 processes the multiple workpieces 200 on the trays 300 in sequence. Before the laser engraving component 11 processes each workpiece 200, the detection mechanism 30 first positions the workpiece 200 to be processed. Then, the detection mechanism 30 sends the position information of the workpiece 200 to the clamping mechanism 20. According to the received position information, the clamping mechanism 20 drives the material tray 300 to move so that the laser energy generated by the laser engraving component 11 can irradiate the preset starting point in the processing area of ​​the workpiece 200 to be processed. During the processing of the workpiece 200 by the laser engraving equipment 100, the clamping mechanism 20 drives the material tray 300 to move so that the laser energy can scan the entire processing area from the preset starting point in the processing area of ​​the current workpiece 200.

[0044] Understandably, the feeding mechanism 40 and the first transfer mechanism 50 work together to achieve automatic feeding, thereby improving production efficiency. The clamping mechanism 20 drives the material tray 300 to move, enabling multiple workpieces 200 arranged on the material tray 300 to move relative to the laser engraving assembly 11. This allows the laser engraving assembly 11 to directly process the workpieces 200 on the material tray 300, reducing the need for transfer operations on the workpieces 200 and thus improving efficiency.

[0045] In one embodiment of this implementation, please refer to Figures 1 to 3 The laser engraving equipment 100 also includes a second transfer mechanism 60, which is connected to the laser engraving mechanism 10. The detection mechanism 30 is electrically connected to the second transfer mechanism 60. The clamping mechanism 20 has a receiving groove 21 for fixing the workpiece 200. The detection mechanism 30 is also used to perform shape detection on the workpiece 200 on the material tray 300. The clamping mechanism 20 drives the material tray 300 to move to the bottom side of the second transfer mechanism 60 so that the second transfer mechanism 60 can move the workpiece 200 that does not meet the shape conditions to the receiving groove 21.

[0046] Specifically, the second transfer mechanism 60 includes a lifting driver 61 and a suction nozzle 62. The lifting driver 61 is driven in the Z-direction 600 and is connected to the laser engraving mechanism 10. The suction nozzle 62 is located on the driving end of the lifting driver 61. A receiving groove 21 is formed on the carrier 22 and can move synchronously with the material tray 300. The X-axis linear driver 23 and the Y-axis linear driver 24 can drive the carrier 22 to move horizontally relative to the suction nozzle 62 so that the workpiece 200 on the material tray 300 that does not meet the shape requirements is close to the suction nozzle 62. When the workpiece 200 that does not meet the shape requirements moves to the bottom side of the suction nozzle 62, the lifting driver 61 drives the suction nozzle 62 to move closer to the suction nozzle 62 in the Z-direction 600, and the suction nozzle 62 will pick up the workpiece 200 that does not meet the shape requirements. The X-axis linear driver 23 and the Y-axis linear driver 24 can drive the carrier 22 to move horizontally relative to the suction nozzle 62, so that the receiving groove 21 is close to the suction nozzle 62. When the receiving groove 21 is located at the bottom of the suction nozzle 62, the lifting driver 61 drives the suction nozzle 62 to descend, so as to put the workpiece 200 that does not meet the shape conditions into the receiving groove 21. It should be noted that after the laser engraving assembly 11 finishes processing a workpiece 200, the detection mechanism 30 can perform shape detection on the processed workpiece 200. If the workpiece 200 does not meet the shape conditions, the detection mechanism 30 can record the position information of the workpiece 200 on the tray 300. After the laser engraving assembly 11 finishes processing all the workpieces 200 on a tray 300, the detection mechanism 30 sends the position information of the workpieces 200 that do not meet the shape conditions to the clamping mechanism 20. The clamping mechanism 20, the detection mechanism 30 and the secondary transfer mechanism work together to move the workpieces 200 that do not meet the shape conditions into the receiving groove 21.

[0047] This setup allows workpieces 200 that do not meet the shape requirements to be rejected, reducing the risk of them flowing into the next process.

[0048] In one embodiment of this implementation, please refer to Figure 2 The clamping mechanism 20 has multiple receiving slots 21. Specifically, the multiple receiving slots 21 are arranged at intervals of 50° along the Y direction. It can be understood that providing multiple receiving slots 21 can reduce the risk of the workpiece 200 overflowing from the receiving slots 21 when they are full.

[0049] In one embodiment of this implementation, please refer to Figure 1 and Figure 9 , Figure 9 yes Figure 1 A schematic diagram of the unloading mechanism 70 is shown. The laser engraving equipment 100 also includes the unloading mechanism 70, which is connected to the laser engraving mechanism 10. The unloading mechanism 70 is used to store the stacked material trays 300. The first transfer mechanism 50 is also used to move the material trays 300 on the clamping mechanism 20 to the unloading mechanism 70.

[0050] Specifically, the unloading mechanism 70 is located on one side of the clamping mechanism 20 along the Y direction 500. It can be understood that the unloading mechanism 70 and the first transfer mechanism 50 work together to achieve automatic unloading, thereby improving production efficiency.

[0051] In one embodiment of this implementation, please refer to Figure 1 , Figures 7 to 9 The first transfer mechanism 50 includes a motion component 51 and two connecting components 52. The two connecting components 52 are mounted on the motion component 51. The motion component 51 is used to drive the connecting components 52 to move. The connecting components 52 are used to connect with the material tray 300. When one of the connecting components 52 drives the material tray 300 on the feeding mechanism 40 to move toward the clamping mechanism 20, the other connecting component 52 drives the material tray 300 on the clamping mechanism 20 to move toward the feeding mechanism 70.

[0052] Specifically, the feeding mechanism 40, clamping mechanism 20, and unloading mechanism 70 are arranged at intervals along the Y direction 500. The interval between the feeding mechanism 40 and the clamping mechanism 20 is equal to the interval between the clamping mechanism 20 and the unloading mechanism 70. Two connecting components 52 are also arranged at intervals along the Y direction 500, with the interval between them equal to the interval between the feeding mechanism 40 and the clamping mechanism 20. The motion component 51 can drive the two connecting components 52 to move along the Y direction 500. The connecting component 52 is a clamp adapted to the material tray 300, and the motion component 51 is a linear actuator with a driving direction along the Y direction 500. It is understood that this arrangement allows feeding and unloading on the clamping mechanism 20 to occur simultaneously, which is beneficial for improving production efficiency.

[0053] In one embodiment of this implementation, please refer to Figure 1 , Figure 7 and Figure 8 The feeding mechanism 40 includes a feeding bin 41 and a discharging component 42. The feeding bin 41 is used to store the material tray 300. The feeding bin 41 has an opening at the top. The discharging component 42 is connected to the feeding bin 41 and is used to drive the material tray 300 in the feeding bin 41 to move to the opening at the top of the feeding bin 41. The first transfer mechanism 50 can move the material tray 300 out of the feeding bin 41 from the opening at the top of the feeding bin 41.

[0054] Specifically, the discharge assembly 42 includes a discharge linear motor 421 and a discharge lifting component 422. The stator of the discharge linear motor 421 is connected to the feeding bin 41, and the mover of the discharge linear motor 421 is connected to the discharge lifting component 422. The driving direction of the discharge linear motor 421 is Z-direction 60°. The discharge lifting component 422 can abut against the lowest material tray 300 in the feeding bin 41. The discharge linear motor 421 can drive the discharge lifting component 422 to rise, so that the material tray 300 stacked in the feeding bin 41 moves vertically upward and approaches the opening above the feeding bin 41. During the feeding process, the first transfer mechanism 50 removes the topmost tray 300 from the feeding bin 41 and moves it to the clamping mechanism 20. The tray 300 located below the original topmost tray 300 becomes the topmost tray 300 in the feeding bin 41 at this time. The discharge linear motor 421 drives the discharge lifting component 422 to rise a preset distance, and drives the remaining trays 300 in the feeding bin 41 to rise, so that the topmost tray 300 in the feeding bin 41 is at a preset height. Then, the first transfer mechanism 50 moves the topmost tray 300 in the feeding bin 41 to the clamping mechanism 20. The cycle of the above process constitutes the feeding action of the first transfer mechanism 50.

[0055] Understandably, the opening of the feeding bin 41 is located at the top of the feeding bin 41, which facilitates the first transfer mechanism 50 to remove the material tray 300. The discharge component 42 keeps the material tray 300 at the top of the feeding bin 41 at a preset height, so that the first transfer mechanism 50 can grab the material tray 300 from a fixed position in each cycle of the feeding action, which is conducive to the stable feeding of the laser engraving equipment 100.

[0056] In one embodiment of this implementation, please refer to Figure 1 , Figure 8 and Figure 9 The feeding mechanism 70 is equipped with a feeding bin 71 and a return component 72. The return component 72 is connected to the feeding bin 71. The feeding bin 71 has an opening at the top. The feeding bin 71 is used to store the material tray 300. The first transfer mechanism 50 can move the material tray 300 into the feeding bin 71 from the opening at the top of the feeding bin 71. The return component 72 can drive the material tray 300 entering from the opening at the top of the feeding bin 71 to move to the bottom of the feeding bin 71.

[0057] Specifically, the return assembly 72 includes a return linear motor 721 and a return support 722. The stator of the return linear motor 721 is connected to the discharge bin 71, and the mover of the return linear motor 721 is connected to the return support 722. The drive direction of the return linear motor 721 is vertical. The return support 722 can abut against the bottommost tray 300 in the discharge bin 71. The return linear motor 721 can drive the return support 722 to descend, so that the tray 300 stacked in the discharge bin 71 moves vertically downward and towards the bottom of the discharge bin 71. During the unloading process, the first transfer mechanism 50 moves the tray 300 from the clamping mechanism 20 to the unloading bin 71, and puts the tray 300 into the unloading bin 71 through the opening above the unloading bin 71. This tray 300 becomes the tray 300 stacked on top of the unloading bin 71 at this time. The return linear motor 721 drives the return support 722 to descend a preset distance, and lowers all the trays 300 in the unloading bin 71 so that the tray 300 stacked on top of the unloading bin 71 is at a preset height. Subsequently, the first transfer mechanism 50 moves another tray 300 from the clamping mechanism 20 to the unloading bin 71. The cycle of the above process constitutes the unloading action of the first transfer mechanism 50.

[0058] Understandably, the opening of the unloading bin 71 is located at the top of the unloading bin 71, which facilitates the first transfer mechanism 50 to put the material tray 300 in. The return component 72 keeps the material tray 300 at the top of the unloading bin 71 at a preset height, so that the first transfer mechanism 50 can put the material tray 300 down from a fixed position in each cycle of the unloading action, which is conducive to the stable unloading of the laser engraving equipment 100.

[0059] In one embodiment of this implementation, please refer to Figure 7 The feeding mechanism 40 includes a feeding bin 41 and a feeding drawer 43. The feeding drawer 43 is movably connected to the feeding bin 41. The feeding drawer 43 is used to place the material tray 300. The feeding drawer 43 can drive the material tray 300 in and out of the feeding bin 41.

[0060] Specifically, the feeding drawer 43 and the feeding bin 41 can slide together along the X direction 400°.

[0061] Understandably, the loading drawer 43 is used by the operator to load the pallet 300 into the upper material hopper 41. When the loading drawer 43 exits the upper material hopper 41, the operator can place the pallet 300 onto the loading drawer 43. At this time, the loading lifting component is located below the upper material hopper 41 and is positioned lower than the loading drawer 43 in the Z direction 600. After placing the pallet 300 on the loading drawer 43, the operator pushes the loading drawer 43 to move it in the X direction 400. The loading drawer 43 carries the pallet 300 into the upper material hopper 41 and moves it above the loading lifting component. Then, the loading lifting component pushes the stacked pallets 300 into the opening above the upper material hopper 41 to complete the process of replenishing the pallet 300 to the loading mechanism 40. This arrangement facilitates the operator in replenishing the pallet 300 to the loading mechanism 40.

[0062] In some other embodiments, the feeding mechanism 70 includes a feeding drawer 73 that can slide along the X direction 400 and engage with the feeding bin 71.

[0063] Understandably, the material drawer is used by the operator to retrieve the material tray 300 from the material hopper 71. During the material unloading process of the laser engraving equipment 100, the material trays 300 stacked on the return support 722 gradually increase in number. The return support 722 drives the material trays 300 to gradually descend relative to the material drawer 73. After the return support 722 descends until the material tray 300 abuts against the material drawer 73, the material drawer 73 can restrict the descent of the material tray 300. Subsequently, the return support 722 continues to descend and separates from the material tray 300. At this point, the material drawer 73 can drive the material tray 300 out of the material hopper 71, and the operator can retrieve the material tray 300 from the material drawer 73. This arrangement facilitates the operator's retrieval of the material tray 300 from the material unloading mechanism 70.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
