[0034] Referring to Figure 1 As shown, this application provides a laser marking device 100. The laser marking device 100 mainly includes a frame 10, a conveyor line 20, a laser marking machine 30, and a grasping and flipping assembly 40. Specifically:

[0035] The frame 10 is the support structure of the entire device, which can ensure the stable installation of all components and can withstand various forces and vibrations during operation.

[0036] The conveyor line 20 is disposed on the frame 10 and is used to convey the boat plate 200 on which the workpiece is placed. A marking station is provided on the conveyor line 20. Specifically, the conveyor line 20 is used to convey the workpiece from one end of the frame 10 to the other end. During the conveying process, it will pass through the marking station provided thereon, and the marking station is the position where the laser marking machine 30 operates.

[0037] The laser marking machine 30 is disposed on the frame 10 corresponding to the conveyor line 20, and it performs engraving, marking, or cutting on the surface of the workpiece by emitting a laser beam with a high energy density. The output head of the laser marking machine 30 is correspondingly disposed above the marking station. In this way, when the workpiece is conveyed to the marking station, the laser beam can irradiate the marking area of the workpiece below for marking operations.

[0038] The grasping and flipping assembly 40 is disposed corresponding to the marking station and is used to grasp the workpiece positioned at the marking station for lifting and flipping, so as to preprocess the workpiece before laser marking to make the marking area provided on the workpiece correspond to the output head. Specifically, this assembly can accurately grasp the workpiece positioned at the marking station and lift it to a certain height and flip it if necessary. This can keep the marking area on the workpiece aligned with the output head to ensure the accuracy and quality of marking.

[0039] Therefore, the technical solution claimed by the technical solution of the present application can achieve the effect of marking the surface of the workpiece facing away from the output head, thereby improving the adaptability of the laser marking device 100.

[0040] Refer to Figure 2 As shown, in some embodiments, the grasping and flipping assembly 40 includes a bracket 41, a first transverse plate 42, and a grasping and flipping mechanism 43; the bracket 41 is disposed on the frame 10 across the conveying line 20 corresponding to the marking station; the first transverse plate 42 is movably mounted on the bracket 41 in the vertical direction; the grasping and flipping mechanism 43 is disposed on the first transverse plate 42 for grasping the workpiece positioned at the marking station and driving it to flip.

[0041] In this embodiment, the bracket 41 is the basic structure of the entire grasping and flipping assembly 40, providing a stable support platform for subsequent components (such as the first transverse plate 42 and the grasping and flipping mechanism 43), and ensuring stability during operation. Further, the bracket 41 is composed of four guiding support columns. These four columns are grouped in pairs and are respectively disposed on both sides of the conveying line 20 to form a stable support frame.

[0042] The first transverse plate 42 is movably mounted on the bracket 41 in the vertical direction, specifically on the four guiding support columns of the bracket 41, such that the first transverse plate 42 can freely move in the vertical direction to adapt to the grasping requirements of workpieces of different heights. Among them, the first transverse plate 42 is connected to the guiding support columns through sliding bearings, and the design of the sliding bearings reduces friction, making the movement of the first transverse plate 42 smoother and more stable.

[0043] Further, the grasping and flipping mechanism 43 is disposed on the first transverse plate 42 and moves with it in the vertical direction. The main function of this mechanism is to grasp the workpiece positioned at the marking station and drive it to flip, thereby meeting specific requirements in the production process.

[0044] Refer to Figure 2 As shown, in some embodiments, a first driving cylinder 44 is disposed on the first transverse plate 42; the grasping and flipping assembly 40 further includes a second transverse plate 45 disposed opposite to the upper side of the first transverse plate 42, and a second driving cylinder 46 is disposed on the second transverse plate 45, and the output ends of the first driving cylinder 44 and the second driving cylinder 46 are connected.

[0045] In this embodiment, through the cooperative drive of the first driving cylinder 44 and the second driving cylinder 46, the first transverse plate 42 is driven to lift the grasping and flipping assembly 40 to different heights to meet the lifting requirements of the workpiece.

[0046] Exemplarily, the driving stroke of the first driving cylinder 44 is 30 mm, and the driving stroke of the second driving cylinder 46 is 50 mm. When the output ends of the first driving cylinder 44 and the second driving cylinder 46 are connected, the stroke of the first transverse plate 42 can reach 80 mm. In specific applications, if only a height increase of 30 mm is required, only the first driving cylinder 44 can be driven to act; if only a height increase of 50 mm is required, only the second driving cylinder 46 can be driven to act, so as to meet different stroke requirements.

[0047] Refer to Figure 2 As shown, in some embodiments, the grasping and flipping mechanism 43 is movably arranged on the first transverse plate 42, and the moving direction of the grasping and flipping mechanism 43 is a lateral movement perpendicular to the conveying line 20.

[0048] In this embodiment, the grasping and flipping mechanism 43 can perform a lateral movement in a direction perpendicular to the conveying line 20, so as to adjust the position to adapt to the grasping of workpieces in different position states. For example, the workpieces can be placed on the ship plate 200 in a front and back state according to requirements. In the front placement state, the part of the workpiece to be grasped is close to one side of the conveying line 20, while in the back placement state, the part of the workpiece to be grasped is close to the other side of the conveying line 20. At this time, the slidably arranged grasping and flipping mechanism 43 can adjust the position to achieve the grasping function and further perform flipping after lifting. It can be immediate because the workpiece placement states are different, so different lifting heights are required for flipping.

[0049] Refer to Figure 2 As shown, in some embodiments, the grasping and flipping mechanism 43 includes a rotation driving member 431 and a clamping member 432; the rotation driving member 431 is slidably connected to the lower side of the first transverse plate 42 through a slider; the clamping member 432 is connected to the rotation driving member 431, and the clamping member 432 includes a clamping driving member and clamping jaws connected to the clamping driving member, and the clamping driving member is used to drive the clamping jaws to open / close.

[0050] In this embodiment, the rotation driving member 431 is slidably connected to the lower side of the first transverse plate 42 through a slider, so that the rotation driving member 431 can perform a lateral movement under the first transverse plate 42 to adapt to the grasping of workpieces in different position states. It is responsible for providing rotational power to drive the clamping member 432 and the workpiece thereon to flip. The clamping member 432 is composed of a clamping driving member and clamping jaws connected to the clamping driving member. The clamping driving member is the key component for driving the clamping jaws to move, and the clamping jaws are directly in contact with the workpiece to be grasped. The clamping member 432 is designed to stably grasp the workpiece and maintain a firm grip on the workpiece during the flipping process. The clamping driving member realizes the clamping and releasing of the workpiece by driving the opening and closing actions of the clamping jaws.

[0051] Refer to Figure 1As shown, in some embodiments, the laser marking device 100 further includes a dust suction hood assembly 50. The dust suction hood assembly 50 is disposed over the marking station and is used to remove the dust generated during the laser marking process.

[0052] It can be understood that during the laser marking process, due to the ablation or vaporization of the material surface, a certain amount of dust and particles will be generated. The purpose of the dust suction hood assembly 50 is to collect the generated dust and particles to prevent them from scattering into the working environment, thereby keeping the working area clean.

[0053] The dust suction hood assembly 50 generally includes a hood body and a dust suction fan connected to the hood body, which work together to remove dust to the greatest extent without affecting the marking quality.

[0054] Refer to Figure 2 As shown, in some embodiments, the laser marking device 100 further includes a positioning and lifting mechanism 60. The positioning and lifting mechanism 60 is correspondingly disposed below the marking station and is used to lift the ship plate 200 after positioning the ship plate 200.

[0055] In this embodiment, the primary function of the positioning and lifting mechanism 60 is to ensure that the ship plate 200 can be accurately and stably positioned on the marking station. Once the ship plate 200 is accurately positioned, the positioning and lifting mechanism 60 will perform a lifting action to lift the ship plate 200 and send the part of the workpiece to be grabbed into the jaws of the grasping and flipping mechanism 43, facilitating the grasping of the workpiece on the ship plate 200 by the grasping and flipping mechanism 43.

[0056] Refer to Figure 1 As shown, in some embodiments, a detection station is provided at the inlet of the conveyor line 20. A plurality of detection devices are provided corresponding to the detection station, and each detection device is used to detect the workpiece on the ship plate 200 at the inlet. Exemplarily, the detection devices at least include a first detection device 71 and a second detection device 72. The first detection device 71 is disposed on the side of the detection station and is used to detect whether the heights of all parts of the workpiece on the ship plate 200 meet the standards; the second detection device 72 is disposed above the detection station and is used to detect whether the shapes and sizes of all parts of the workpiece on the ship plate 200 meet the standards.

[0057] Among them, both the first detection device 71 and the second detection device 72 can adopt a vision detection system to capture images of the workpiece through a camera and use image processing technology to analyze and identify the images. The purpose of each detection device is to ensure the stability and compatibility of the workpiece during subsequent processing or assembly.

[0058] The above are only partial or preferred embodiments of the present application. Neither the text nor the drawings can limit the scope of protection of the present application. Any equivalent structural transformation made using the content of the specification and drawings of the present application under the overall concept of the present application, or any direct / indirect application in other related technical fields, is included within the scope of protection of the present application.
