[0036] To make the objectives, technical solutions, and advantages of this application more clear, the following will further describe the embodiments of this application in detail with reference to the accompanying drawings.

[0037] In the description of this application, it should be understood that the orientation or positional relationships indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings. These are only for the convenience of describing this application 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 thus should not be construed as a limitation to this application.

[0038] As mentioned above, laser marking is a marking method that uses a laser to locally irradiate the product to be marked, causing the surface material of the product to be marked to vaporize or change color, thereby leaving a permanent mark. Laser marking can create various characters, symbols, patterns, etc. on the product surface of the product to be marked, which can play a role in anti-counterfeiting or identification. Currently, laser marking equipment only marks the products to be marked on a single production line. However, since the products to be marked need to be marked after the testing is completed, and the testing time of the products to be marked is much longer than the marking time of the laser marking equipment for the products to be marked, the laser marking equipment is idle for most of the time. For example, if the testing time of the product to be marked is 10 minutes, and the laser marking time of the laser marking equipment for the product to be marked is 3 minutes, then the laser marking equipment only works for 3 minutes within 10 minutes and is idle for 7 minutes, resulting in a low utilization rate.

[0039] In the embodiment of this application, the laser marking equipment includes a base, a conveying module, a robotic arm, and a marking module. The conveying module and the robotic arm are arranged on the base. The conveying module includes a tray and a conveying track. The tray can slide along the conveying track, can pick up the products to be marked from the first production line or the second production line, and transport the products to be marked to the first position. The robotic arm grabs the product to be marked at the first position and transports the product to be marked to the second position. The marking module performs laser marking on the product to be marked at the second position, thereby realizing the marking operation. Since the tray can pick up the products to be marked from the first production line when it slides to the first end of the conveying track, and the tray can pick up the products to be marked from the second production line when it slides to the second end of the conveying track, the laser marking equipment can mark the products to be marked from the second production line after marking the products to be marked from the first production line. Compared with the laser marking equipment in the prior art that only marks the products on a single production line, the idle time of the laser marking equipment is less. It can laser mark the products on another production line while a production line is testing the products, and the utilization rate of the equipment is higher.

[0040] It should be noted that the various specification drawings of this application are only for facilitating the description and understanding of this embodiment, and do not serve as any limitation to this application. They are not necessarily drawn to actual scale. It should be understood that for the convenience of description, in this application, the products before laser marking, the products after laser marking is completed, the products undergoing laser marking, as well as the marked finished products and marked waste products are collectively referred to as products to be marked.

[0041] The following will describe in detail the laser marking device provided by the embodiments of this application with reference to the drawings.

[0042] Figure 1 is a schematic diagram of a laser marking device provided by an embodiment of this application. As Figure 1 shown, the laser marking device 10 includes: a base 11, a conveying module 13, a robotic arm 12, and a marking module 14. The robotic arm 12 and the conveying module 13 are disposed on the base 11. The conveying module 13 includes a conveying track 131 and a tray 132. The tray 132 is configured to move along the conveying track 131. When the tray 132 moves along the conveying track 131 to the first end of the conveying track 131, it can pick up the products to be marked from the first production line, and when the tray 132 moves along the conveying track 131 to the second end of the conveying track 131, it can pick up the products to be marked from the second production line. And after picking up the products to be marked, it moves along the conveying track 131 to the first position. After the tray 132 moves to the first position, the robotic arm 12 can grab the products to be marked from the tray 132 and transport the products to be marked to the second position. The marking module 14 can perform laser marking on the products to be marked located at the second position.

[0043] The base 11 can be disposed on the ground. The conveying module 13 and the robotic arm 12 are fixedly disposed on the base 11. The conveying module 13 includes a conveying track 131 and a tray 132. The tray 132 can slide along the conveying track 131. In one example, both ends of the conveying track 131 can be connected to the production line, or the conveying track 131 can be disposed below the production line. When the production line finishes testing the products to be marked, the products to be marked can fall onto the tray 132 of the conveying track 131 under the action of gravity, or the feeding mechanism provided on the production line can place the products to be marked on the tray 132, thereby realizing picking up the products to be marked through the tray 132.

[0044] When the tray 132 moves along the conveying track 131 to the first end of the conveying track 131, it can pick up the products to be marked on the first production line disposed near the first end of the conveying track 131. When the tray 132 moves along the conveying track 131 to the second end of the conveying track 131, it can pick up the products to be marked on the second production line disposed near the second end of the conveying track 131. The products to be marked from the first production line and the second production line can be the same products or different products.

[0045] After the tray 132 picks up the product to be marked from the first production line or the second production line, it can move along the transfer track 131 to the first position. In one example, the first position can be directly below the marking module 14. When the tray 132 moves to the first position, the robotic arm 12 grabs the product to be marked on the tray 132 and drives the product to be marked to the second position, and the marking module 14 performs laser marking on the product to be marked at the second position.

[0046] In the embodiment of the present application, the laser marking device 10 includes a base 11, a transfer module 13, a robotic arm 12, and a marking module 14. The transfer module 13 and the robotic arm 12 are arranged on the base 11. The transfer module 13 includes a tray 132 and a transfer track 131. The tray 132 can slide along the transfer track 131, can pick up the product to be marked from the first production line or the second production line, and transport the product to be marked to the first position. The robotic arm 12 grabs the product to be marked at the first position and transports the product to be marked to the second position. The marking module 14 performs laser marking on the product to be marked at the second position, thereby realizing the marking operation. Since the tray 132 can pick up the product to be marked from the first production line when it slides to the first end of the transfer track 131, and the tray 132 can pick up the product to be marked from the second production line when it slides to the second end of the transfer track 131, the laser marking device 10 can perform marking on the product to be marked from the second production line after completing the marking of the product to be marked from the first production line. Compared with the laser marking device 10 in the prior art that only marks the products on a single production line, the laser marking device 10 has less idle time and can perform laser marking on the products on another production line when testing the products on one production line, and the utilization rate of the device is relatively high.

[0047] Figure 2 is a schematic diagram of a transfer module provided by an embodiment of the present application, as Figure 2As shown in the figure, the tray 132 includes a first slider 1321, a first loading platform 1322, a second slider 1323 and a second loading platform 1324. Both the first slider 1321 and the second slider 1323 are connected to the transfer track 131. A first through hole is provided on the first slider 1321, and a second through hole is provided on the second slider 1323. The first surface of the first loading platform 1322 is used to provide a loading surface. The second surface of the first loading platform 1322 includes a first trapezoidal protrusion. When the first loading platform 1322 is attached to the first slider 1321, the first trapezoidal protrusion is located within the first through hole. The first surface of the second loading platform 1324 is used to provide a loading surface. The second surface of the second loading platform 1324 includes a second trapezoidal protrusion. When the second loading platform 1324 is attached to the second slider 1323, the second trapezoidal protrusion is located within the second through hole.

[0048] The transfer track 131 includes a first track 1311 and a second track 1312 arranged in parallel. The first side of the first track 1311 includes a first driving mechanism 1331. The first slider 1321 is connected to the first driving mechanism 1331. The second side of the first track 1311 faces the first side of the second track 1312. A second driving mechanism 1332 is provided on the second side of the second track 1312. The second slider 1323 is connected to the second driving mechanism 1332. The first driving mechanism 1331 is used to drive the first slider 1321 to move from the first end of the transfer track 131 to the first position. The second driving mechanism 1332 is used to drive the second slider 1323 to move from the second end of the transfer track 131 to the first position.

[0049] The working process of the product to be marked from the second production line and the second slider 1323 is similar to that of the first slider 1321 in the above example. The only difference is that the second slider 1323 slides from the second end of the transfer track 131 to the first position under the drive of the second driving mechanism 1332, which will not be elaborated here.

[0050] In one example, the sizes and shapes of the first through hole and the second through hole are the same as those of the first trapezoidal protrusion and the second trapezoidal protrusion. When the first loading platform 1322 is attached to the first slider 1321 or the second loading platform 1324 is attached to the second slider 1323, the first trapezoidal protrusion fits with the first through hole, and the second trapezoidal protrusion fits with the second through hole to achieve the positioning of the first loading platform 1322 and the second loading platform 1324.

[0051] In another example, as Figure 2 shown, the first loading platform 1322 and the second loading platform 1324 may include grooves. When the product to be marked is located on the first loading platform 1322 or the second loading platform 1324, part of the product to be marked is embedded in the grooves, so that the product to be marked will not move when the slider slides, and the position of the product to be marked is positioned.

[0052] In an embodiment of the present application, the tray 132 includes a first slider 1321, a first loading platform 1322, a second slider 1323, and a second loading platform 1324. Thus, the products to be marked from the first production line or the second production line can be transported from both ends of the transfer track 131 to the first position by the two sliders, realizing laser marking on the products to be marked from the two production lines. Since the first slider, the first loading platform, the second slider, and the second loading platform are provided, the products to be marked from the first production line and the products to be marked from the second production line can be picked up simultaneously, preventing the tray from being unable to pick up the products to be marked from the two production lines simultaneously when the first production line and the second production line produce the products to be marked synchronously.

[0053] In a possible implementation, as Figure 2 shown, the transfer module 13 further includes a lifting mechanism 134. The lifting mechanism 134 is disposed on the base 11. After the tray 132 moves to the first position and receives the first control signal, the lifting mechanism 134 can drive the first loading platform 1322 or the second loading platform 1324 to rise through the lifting rod 1341 to transport the product to be marked to the second position. After the marking module 14 finishes marking the product to be marked on the first loading platform 1322 or the second loading platform 1324, the lifting rod 1341 is used to drive the first loading platform 1322 or the second loading platform 1324 to descend to fit with the first slider 1321 or the second slider 1323, so that the robotic arm 12 can grab the product to be marked from the tray 132.

[0054] The following is an illustration with an example. When the product to be marked on the first production line is placed on the first carrier 1322 at the first end of the transfer track 131, the first driving mechanism 1331 drives the first slider 1321 to slide from the first end of the transfer track 131 to the first position. At this time, if the lifting mechanism 134 receives the first control signal, the lifting mechanism 134 transports the first carrier 1322 to the second position through the lifting rod 1341. At this time, the marking module 14 can perform laser marking on the product to be marked located at the second position and on the first carrier 1322. It should be understood that when the marking module 14 performs laser marking on the product to be marked on the first carrier 1322, the marked surface of the product to be marked is the grasping surface of the robotic arm 12. For example: the bottom surface of the product to be marked. After the laser marking of the product to be marked is completed, and when the lifting mechanism 134 receives the second control signal, the lifting rod 1341 of the lifting mechanism 134 descends, driving the first carrier 1322 to descend until it fits with the first slider 1321. At this time, since the laser marking of the grasping surface of the product to be marked has been completed, the robotic arm 12 can grasp the marked grasping surface to complete the marking work on other surfaces to be marked of the product to be marked. It should be noted that after the robotic arm 12 grasps the product to be marked, the first slider 1321 can return to the first end of the transfer track 131 under the drive of the first driving mechanism 1331. It should also be noted that when the grasping surface of the product to be marked does not need to be laser marked, the lifting mechanism 134 will not receive the first control signal, that is, it will not lift or lower the first carrier 1322 through the lifting rod 1341, but directly grasp the product to be marked by the robotic arm 12 to perform laser marking on the surface to be marked of the product to be marked.

[0055] In the embodiment of the present application, the transfer module 13 includes a lifting mechanism 134. When it is necessary to perform laser marking on the grasping surface of the robotic arm 12 on the product to be marked, the first carrier 1322 or the second carrier 1324 can be lifted to the second position through the lifting mechanism 134, so that the marking module 14 performs laser marking on the grasping surface of the product to be marked carried on the first carrier 1322 or the second carrier 1324 and opposite to the marking module 14. Thus, the marked grasping surface can be grasped by the robotic arm 12, without the need for the robotic arm 12 to grasp the product to be marked from the first carrier 1322 or the second carrier 1324 multiple times, simplifying the laser marking process. While realizing laser marking on multiple surfaces to be marked of the product to be marked, the working efficiency of the laser marking device 10 is improved.

[0056] Figure 3 is a schematic diagram of a laser marking device including a finished product transfer unit provided by an embodiment of the present application, as Figure 3As shown in the figure, the laser marking device 10 further includes a first finished product conveying unit 151 and a second finished product conveying unit 152. The first finished product conveying unit 151 and the second finished product conveying unit 152 are respectively connected to the base 11. The robotic arm 12 can place the to-be-marked products that are qualified for marking and come from the first production line onto the first finished product conveying unit 151, and place the to-be-marked products that are qualified for marking and come from the second production line onto the second finished product conveying unit 152. The first finished product conveying unit 151 can convey the to-be-marked products placed by the robotic arm 12 to the first finished product area, and the second finished product conveying unit 152 can convey the to-be-marked products placed by the robotic arm 12 to the second finished product area.

[0057] The laser marking device 10 further includes a first finished product conveying unit 151 and a second finished product conveying unit 152. The first ends of the first finished product conveying unit 151 and the second finished product conveying unit 152 are respectively connected to the base 11, and the second ends of the first finished product conveying unit 151 and the second finished product conveying unit 152 are respectively located outside the laser marking device 10. In one example, a first finished product area is provided directly below the second end of the first finished product conveying unit 151, and a second finished product area is provided directly below the second end of the second conveyor belt.

[0058] After the marking module 14 finishes marking the to-be-marked product located at the second position grabbed by the robotic arm 12, the robotic arm 12 places the to-be-marked products that are qualified for marking and come from the first production line onto the first end of the first finished product conveying unit 151, and places the to-be-marked products that are qualified for marking and come from the second production line onto the first end of the second finished product conveying unit 152. The first finished product conveying unit 151 and the second finished product conveying unit 152 convey the to-be-marked products that are qualified for marking placed by the robotic arm 12 from the first end to the second end to be conveyed to the corresponding finished product area.

[0059] In one example, as Figure 3 shown, the first finished product conveying device and the second finished product conveying device can be chutes. The distance from the first end of the chute to the ground is greater than the distance from the second end of the chute to the ground. In another example, the first finished product conveying unit 151 and the second finished product conveying unit 152 can be conveyor belts. The conveying directions of the first finished product conveying unit 151 and the second finished product conveying unit 152 are perpendicular to the conveying track 131 and parallel to the base 11, that is, the first finished product conveying unit 151 and the second finished product conveying unit 152 are arranged parallel to the base 11.

[0060] In the embodiment of the present application, the laser marking device 10 further includes a first finished product conveying unit 151 and a second finished product conveying unit 152. The first finished product conveying unit 151 can convey the qualified products to be marked from the first production line placed by the robotic arm 12 to the first finished product area, and the second finished product conveying unit 152 can convey the qualified products to be marked from the second production line placed by the robotic arm 12 to the second finished product area. Thus, the products to be marked that have been marked and are qualified can be conveyed out of the laser marking device 10. Since two finished product conveying units are provided, the products to be marked that are qualified and come from different production lines can be conveyed to different finished product areas, preventing the finished products after marking from being confused.

[0061] Figure 4 It is a schematic diagram of a laser marking device including a chute provided by an embodiment of the present application. As Figure 4 shown, the laser marking device 10 further includes a first chute 161 and a second chute 162. The height of the first end of the first chute 161 is greater than the height of the second end of the first chute 161, and the height of the first end of the second chute 162 is greater than the height of the second end of the second chute 162. The first end of the first chute 161 is disposed opposite to the first end of the second chute 162. The robotic arm 12 can place the products to be marked that are unqualified and come from the first production line at the first end of the first chute 161, and place the products to be marked that are unqualified and come from the second production line at the first end of the second chute 162. The first chute 161 can convey the products to be marked placed by the robotic arm 12 to the first waste area, and the second chute 162 can convey the products to be marked placed by the robotic arm 12 to the second waste area.

[0062] The laser marking device 10 further includes a first chute 161 and a second chute 162. The first chute 161 and the second chute 162 are in a groove structure, that is, the first chute 161 includes a slideway and side walls, and the side walls are disposed on both sides of the slideway. The height of the first end of the first chute 161 and the second chute 162 is greater than the height of the second end. In an example, as Figure 4 shown, both the first chute 161 and the second chute 162 include a first sub-chute and a second sub-chute. The first end of the first sub-chute is higher than the second end of the first sub-chute. The first end of the second sub-chute is connected to the second end of the first sub-chute, and the second sub-chute is parallel to the base 11, that is, the first end and the second end of the second sub-chute have the same height. The first ends of the first chute 161 and the second chute 162 are located inside the laser marking device 10 and are disposed opposite to each other. The second ends of the first chute 161 and the second chute 162 are located outside the laser marking device 10.

[0063] The robotic arm 12 places the products to be marked that are unqualified in marking from the first production line on the first end of the first chute 161, and places the products to be marked that are unqualified in marking from the second production line on the first end of the second chute 162. The first chute 161 and the second chute 162 convey the products to be marked that are unqualified in marking placed by the robotic arm 12 from the first end to the second end, so as to convey them to the corresponding waste areas. In one example, the first waste area and the second waste area can be respectively located at the bottom of the second end of the first chute 161 and the bottom of the second end of the second chute 162. After the robotic arm 12 places the products to be marked that are unqualified in marking on the first chute 161 or the second chute 162, the products to be marked slide along the first chute 161 or the second chute 162 under the action of gravity and fall into the first waste area or the second waste area.

[0064] In the embodiment of the present application, the laser marking device 10 further includes a first chute 161 and a second chute 162. The first chute 161 can convey the products to be marked that are unqualified in marking from the first production line placed by the robotic arm 12 to the first waste area, and the second chute 162 can convey the products to be marked that are unqualified in marking from the second production line placed by the robotic arm 12 to the second waste area. Thus, the products to be marked that are unqualified in marking can be conveyed out of the laser marking device 10. Since two chutes are provided, the products to be marked that are unqualified in marking from different production lines can be conveyed to different waste areas, and the waste products that are unqualified in marking can be prevented from being confused.

[0065] Figure 5 is a schematic diagram of another laser marking device provided by the embodiment of the present application, as Figure 5 shown, the laser marking device 10 includes a control module 17. The marking module 14 includes a first vision unit. The first vision unit can collect the first image of the product to be marked when the product to be marked is in the second position, and send the first image to the control module 17. The control module 17 can send a marking instruction to the marking module 14 after receiving the first image. Among them, the marking instruction includes marking angle compensation and marking position compensation. The marking module 14 can perform laser marking on the target position on the product to be marked according to the marking instruction.

[0066] As Figure 5 shown, the laser marking device 10 includes a control module 17. The control module 17 can be a module with a control function such as a computer or a single-chip microcomputer. The control module 17 is arranged on one side of the marking module 14. The control module 17 can control the conveying module 13, the robotic arm 12 and the marking module 14.

[0067] The marking module 14 is provided with a first vision unit, and the first vision unit can collect images. Specifically, the first vision unit can be a camera, a webcam, etc. In one example, the first vision unit is arranged on the side of the marking module 14 opposite to the conveying track 131.

[0068] When the product to be marked is at the second position, the first vision unit can collect a first image of the product to be marked and send the first image to the control unit. When receiving the first image, the control unit determines the deviation angle and deviation coordinates of the product to be marked in the first image. It should be understood that since the position of the product to be marked on the tray 132 may not be the same each time, after the robotic arm 12 grabs the product to be marked and transports it to the second position, there may be an angular deviation. For example, the target position of the product to be marked deviates from the normal marking position by a certain angle, or the x-axis and y-axis coordinates of the target position of the product to be marked deviate from the normal marking position by a certain coordinate. After determining the deviation angle and deviation coordinates, the control unit sends a marking instruction to the marking module 14. The marking instruction at least includes marking angle compensation and marking position compensation.

[0069] The marking module 14 adjusts the laser emission angle and laser emission position according to the marking angle compensation and marking position compensation in the marking instruction, so as to perform laser marking at the target position on the product to be marked, preventing the laser marking from exceeding the target position due to the position change of the product to be marked. It should be understood that the marking instruction can be obtained by image recognition of the first image, or can be selected and input by the user according to the collected first image. For example, the user inputs the marking position compensation and marking angle compensation.

[0070] In the embodiment of the present application, the laser marking device 10 includes a control module 17, whereby the control module 17 can control the conveying module 13, the robotic arm 12 and the marking module 14 of the laser marking device 10 to realize laser marking on the products to be marked from the first production line and the second production line. The marking module 14 includes a first vision unit, whereby the first vision unit can collect a first image of the product to be marked at the second position, whereby the control unit can send a marking instruction, and the marking module 14 can compensate for the marking position and marking angle according to the marking instruction to perform laser marking at the target position on the product to be marked, whereby it can prevent the marking module 14 from not performing laser marking at the target position when laser marking due to the different positions of the product to be marked when grabbed by the robotic arm 12, and can improve the qualification rate of marking the products to be marked.

[0071] In a possible implementation, after the marking module 14 finishes marking the product to be marked, the first vision unit can collect a second image of the product to be marked and send the second image to the control module 17. The control module 17 can send a discard instruction to the robotic arm 12 based on the second image. When receiving the discard instruction, the robotic arm 12 can discard the product to be marked from the first production line into the first chute 161 or discard the product to be marked from the second production line into the second chute 162.

[0072] The first vision unit can also collect a second image of the product to be marked after the marking module 14 finishes laser marking the product to be marked. In one example, when multiple surfaces to be marked of the product to be marked need to be marked, the second image of each surface to be marked can be collected after the marking of each surface to be marked is completed. After the first vision unit collects the second image, it sends the second image to the control unit. After receiving the second image, the control unit identifies whether the marking result of the product to be marked is qualified based on the second image. When it is identified as unqualified, it sends a discard instruction to the robotic arm 12. After receiving the discard instruction, the robotic arm 12 moves the grabbed product to be marked from the second position to the first end of the first chute 161 or the second chute 162 to discard the product to be marked into the waste area.

[0073] It should be understood that the control module 17 can also send a qualified instruction to the robotic arm 12 after the laser marking of each surface to be marked of the product to be marked is completed and when it is determined that the marking of the last surface to be marked is qualified based on the second image of the last surface to be marked. At this time, the robotic arm 12 moves the grabbed product to be marked from the second position to the first end of the first finished product conveying unit 151 or the second finished product conveying unit 152. It should be noted that when any surface to be marked of the product to be marked is unqualified, the marking will not continue but will be directly discarded. It should also be understood that the discard instruction can be obtained by performing image recognition on the second image or can be selected and input by the user based on the collected second image. For example, the user inputs a discard instruction to the laser marking system according to the second image.

[0074] In the embodiment of the present application, after the marking module 14 finishes marking the product to be marked, the first vision unit can collect a second image of the product to be marked. The control module 17 can send a discard instruction to the robotic arm 12 based on the second image. When receiving the discard instruction, the robotic arm 12 can move the grabbed product to be marked from the second position to the first end of the first chute 161 or the second chute 162. Thereby, the product to be marked with unqualified marking can be discarded, unqualified products can be screened out in time and discarded, the qualification rate of the product to be marked can be improved, and it is ensured that the products to be marked located in the finished product area are all products to be marked with qualified marking.

[0075] In a possible implementation, such asFigure 1 As shown, the robotic arm 12 includes a grasping unit 121. After the tray 132 moves to the first position, the grasping unit 121 can grasp the product to be marked from the tray 132. The robotic arm 12 can transport the product to be marked grasped by the grasping unit 121 to the second position and make the surface to be marked of the product to be marked face the marking module 14.

[0076] The robotic arm 12 includes a grasping unit 121. The grasping unit 121 can grasp the product to be marked located at the first position. In one example, as Figure 1 shown, the grasping unit 121 can adsorb on the adsorption surface of the product to be marked to achieve the grasping function. The robotic arm 12 may include a plurality of rotating units. One end of the robotic arm 12 is fixed on the base 11. Through the plurality of rotating units, the robotic arm 12 can make the surface to be marked of the product to be marked grasped by the grasping unit 121 face the marking module 14. In one example, the robotic arm 12 can rotate the plurality of rotating units to make different surfaces to be marked of the product to be marked face the marking module 14 respectively.

[0077] In the embodiment of the present application, the robotic arm 12 includes a grasping unit 121. After the tray 132 moves to the first position, the grasping unit 121 can grasp the product to be marked from the tray 132. The robotic arm 12 can transport the product to be marked grasped by the grasping unit 121 to the second position and make the surface to be marked of the product to be marked face the marking module 14. Thus, marking of multiple surfaces to be marked of the product to be marked can be achieved. Since the surface to be marked of the product to be marked is directly made to face the marking module 14 by the robotic arm 12, it is not necessary to put the product to be marked back into the tray 132 and re-grasp it for different surfaces to be marked, simplifying the marking process and improving the efficiency of laser marking of the product to be marked by the laser marking device 10.

[0078] In a possible implementation manner, the grasping unit 121 includes a second vision unit. After the tray 132 moves to the first position, the second vision unit can collect a third image of the product to be marked and send the third image to the control module 17. The control module 17 can send a grasping instruction to the robotic arm 12 based on the third image. The grasping instruction is used to indicate the surface to be marked of the product to be marked. After the grasping unit 121 grasps the product to be marked, the robotic arm 12 can transport the product to be marked to the second position according to the grasping instruction and make the surface to be marked of the product to be marked face the marking module 14.

[0079] The second vision unit is disposed on the grasping unit 121 of the robotic arm 12. When the robotic arm 12 grasps the product to be marked located at the first position, the second vision unit on the grasping unit 121 collects the third image of the product to be marked and sends the third image to the control module 17. The control module 17 can send a grasping instruction to the robotic arm 12 based on the third image. In one example, the third image can be an image with a QR code. The control module 17 identifies the QR code in the third image, determines at least one surface to be marked of the product to be marked, and sends a grasping instruction to the robotic arm 12.

[0080] After receiving the grasping instruction, the robotic arm 12 grasps the product to be marked located at the first position, and rotates multiple rotating units on the robotic arm 12 according to at least one surface to be marked of the product to be marked indicated by the grasping instruction, so that at least one surface to be marked faces the marking module 14 in sequence. The marking module 14 performs laser marking on the surface to be marked facing the marking module 14. It should be understood that the grasping instruction can be obtained by performing image recognition on the third image, or can be selected and input by the user according to the collected third image. For example: the user inputs a grasping instruction to the laser marking system according to the third image.

[0081] In one example, when the control module 17 recognizes that the grasping surface of the robotic arm 12 of the product to be marked needs to be laser marked according to the third image, it first controls the lifting mechanism 134 in the conveying module 13 to lift and lower to perform laser marking on the grasping surface, and after lowering the lifting mechanism 134, it controls the robotic arm 12 to grasp the grasping surface of the product to be marked and perform laser marking on other surfaces to be marked of the product to be marked.

[0082] In the embodiment of the present application, the grasping unit 121 includes a second vision unit. The second vision unit can collect the third image of the product to be marked located at the first position. The control unit can send a grasping instruction to the robotic arm 12 based on the third image. After receiving the grasping instruction, the robotic arm 12 can grasp the product to be marked located at the first position and make the surface to be marked of the product to be marked face the marking module 14. Thus, different surfaces to be marked can face the module respectively. Since the control module 17 sends a grasping instruction according to the third image, when marking products to be marked from two production lines, different surfaces to be marked can be marked according to the marking requirements of different products to be marked, and the laser marking device 10 can be applied to mark different products to be marked.

[0083] Figure 6 is a schematic diagram of a laser marking device including a cleaning module provided in an embodiment of the present application, as Figure 6As shown, the laser marking device 10 further includes a cleaning module 18. The cleaning module 18 is disposed near the base 11. The cleaning port of the cleaning module 18 is disposed opposite to the conveying track 131. The cleaning module 18 can clean the dust generated when the marking module 14 performs laser marking on the product to be marked.

[0084] The laser marking device 10 further includes a cleaning module 18. The cleaning module 18 is disposed near the base 11. In one example, the height of the cleaning port of the cleaning module 18 from the ground is greater than the height of the base 11 from the ground. The cleaning port of the cleaning module 18 is disposed opposite to the conveying track 131. In one example, the cleaning module 18 can be a dust suction device, and the dust suction device can suck the dust generated when the laser marking device 10 performs laser marking on the product to be marked through the cleaning port.

[0085] In the embodiment of the present application, the laser marking device 10 further includes a cleaning module 18. Thus, the dust generated when the product to be marked is laser marked can be cleaned by the cleaning module 18, ensuring the cleanliness inside the laser marking device 10, preventing the occurrence of danger, and preventing the laser marking device 10 from being damaged by dust.

[0086] Figure 7 is a schematic diagram of a laser marking device including an alarm module provided by an embodiment of the present application. As Figure 7 shown, the laser marking device 10 further includes an alarm module 19. The alarm module 19 is disposed outside the laser marking device 10. The alarm module 19 can send an alarm signal when the laser marking device 10 has a fault.

[0087] The laser marking device 10 further includes an alarm module 19. As Figure 7 shown, the alarm module 19 is disposed outside the laser marking device 10. When the laser marking device 10 has a fault, the alarm module 19 sends an alarm signal. In one example, the control module 17 can send an alarm instruction to the alarm module 19 when the laser marking device 10 has a fault. For example: send a high-level signal to the alarm module 19, and the alarm module 19 sends an alarm signal when receiving the alarm instruction. In one example, the alarm module 19 can include a light emitting unit and a sound emitting unit, and can emit a flashing red light or yellow light through the light emitting unit, and emit an alarm sound through the sound emitting unit to realize sending an alarm signal.

[0088] In the embodiment of the present application, the laser marking device 10 further includes an alarm module 19. The alarm module 19 can send an alarm signal when the laser marking device 10 has a fault. Thus, the fault of the laser marking device 10 can be alarmed in time, ensuring that the laser marking device 10 can work normally.

[0089] In a possible implementation, the control module 17 includes a display unit. The display unit can display the working state of the laser marking device 10 and receive touch commands through a touch layer provided on the display unit.

[0090] The control module 17 includes a display unit. The display unit can be a display device such as a display screen. The control module 17 can display the working state of the laser marking device 10 through the display unit. For example, it can display the images collected by the first vision unit and the second vision unit, display the current laser marking process, and so on.

[0091] A touch layer can be integrated on the display unit. A user can send touch commands to the control module 17 through the touch layer. For example, commands such as pause, stop, or start can be sent to the control module 17 through the touch layer.

[0092] In the embodiment of the present application, the control module 17 includes a display unit. The display unit can display the working state of the laser marking device 10 and receive touch commands through a touch layer provided on the display unit. Thus, it can facilitate a user to monitor the working state of the laser marking device 10 and control the laser marking device 10.
