DETAILED DESCRIPTION

[0025] In order to make the technical purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the embodiment described below is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention 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 therefore cannot be understood as a limitation on the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0027] The embodiment of the utility model provides a laser marking machine 100. In order to clearly describe the technical solution of the utility model, the plane where the turntable 121 is located is defined as a vertical plane, the direction perpendicular to the vertical plane is defined as a first direction V1, and the marking direction of the laser emitting device 110 is defined as a second direction V2; the direction perpendicular to the second direction V2 and the first direction V1 is defined as a third direction V3, wherein the plane where the second direction V2 and the third direction V3 are located is the vertical plane.

[0028] See also Figure 1 and Figure 2 In one embodiment, the laser marking machine 100 comprises: a laser emitting device 110, a workpiece positioning device 120, a first supporting component 130, a second supporting component 140 and a driving device 150;

[0029] The laser emitting device 110 is horizontally arranged on the first supporting assembly 130 along the second direction V2, and the marking direction of the laser emitting device 110 is away from the direction of the worker's operation area, and is used for surface treatment of the workpiece;

[0030] The workpiece positioning device 120 includes a turntable 121 and a plurality of clamping assemblies 122 arranged on the plane where the second direction V2 and the third direction V3 are located; the plurality of clamping assemblies 122 are arranged at equal intervals in an annular manner on the edge of the turntable 121 for clamping and fixing the workpiece;

[0031] The driving device 150 is installed on the second supporting member 140 and is used to drive the turntable 121 to rotate intermittently, so that the laser emitting device 110 can continuously and intermittently complete the surface treatment of the workpiece.

[0032] It is understandable that the technical solution of the utility model is to set a turntable 121 and a plurality of clamping assemblies 122 on the turntable 121, and while the laser emitting device 110 performs surface treatment on the workpiece, the operator performs loading and unloading operations on the workpiece on the clamping assembly 122 in the worker's operation area. Therefore, the laser marking process and the loading and unloading process can be carried out simultaneously, which improves the production and processing speed of the workpiece.

[0033] It should also be noted that the above-mentioned intermittent rotation means that when the laser emitting device 110 is marking the workpiece, the turntable 121 stops rotating; after completing the marking of the workpiece, the turntable 121 rotates to allow the next workpiece to enter the marking area, and then stops rotating, thereby rotating in a cycle.

[0034] Please continue reading Figure 1 In a specific embodiment of the utility model, the clamping assembly 122 includes a guide member 1221, an elastic member 1222, a movable clamp 1223 and a fixed clamp 1224; the guide member 1221 passes through the movable clamp 1223 and slidably cooperates with the movable clamp 1223; one end of the guide member 1221 is fixedly connected to the turntable 121, and the other end of the guide member 1221 is fixedly connected to the fixed clamp 1224; the elastic member 1222 is arranged between the turntable 121 and the movable clamp 1223. It can be understood that when the elastic member is a compression spring, the workpiece can be clamped between the movable clamp 1223 and the fixed clamp 1224, and the clamped workpiece can be subjected to laser surface treatment on the clamping assembly 122.

[0035] Optionally, the elastic member 1222 is a tension spring. Further, when the elastic member 1222 is a tension spring, one end of the tension spring is fixedly connected to the rotating disk 121, and the other end of the tension spring is connected to the movable member. At this time, the workpiece can be clamped between the movable clamp 1223 and the rotating disk 121; when the tension spring also has a contraction performance, the workpiece can also be clamped and fixed between the movable clamp 1223 and the fixed clamp 1224.

[0036] It should also be noted that while the laser emitting device 110 is performing surface treatment on the workpiece, the operator needs to perform unloading or loading operations on the workpiece other than the processed workpiece. Specifically, the operator can perform unloading operations and then loading operations when moving the movable clamp 1223. At the same time, it should also be noted that the setting of the guide rod can also provide support for the workpiece, so that the operator can quickly locate the position of the workpiece on the clamping assembly 122.

[0037] In one embodiment, if Figure 2 As shown, a buckle ring 1225 is also provided on one side of the movable clamp 1223. Optionally, in order to facilitate right-hand operation, the buckle ring 1225 is provided on one side of the movable clamp 1223 close to the turntable 121, and the buckle ring 1225 is used to facilitate workers to move the movable clamp 1224, so as to detach or install the workpiece to the clamping assembly 122.

[0038] See also Figure 1 and Figure 2In another specific embodiment of the utility model, the driving device 150 includes a first motor 151, a first rotating member 152, a second rotating member 153, a synchronous belt 154 and an angle sensor 155; the first motor 151 is fixed to the second supporting member 140, and drives the first rotating member 152 to rotate; the second rotating member 153 is fixedly connected to the turntable 121, and the second rotating member 153 rotates synchronously with the first rotating member 152 through the synchronous belt 154; the angle sensor 155 is connected to the first motor 151 by signal, and is used to control the intermittent operation of the first motor 151. It should be noted that the first rotating member 152 and the second rotating member 153 are gears or pulleys, and the synchronous belt 154 is a toothed belt or a belt. Preferably, in order to slow down the rotation speed of the turntable 121 and prevent the rotation of the turntable from accidentally injuring workers, the outer dimensions of the second rotating member 153 are larger than those of the first rotating member 152.

[0039] In a specific embodiment, the first motor 151 is an electromagnetic brake motor. It is understood that the brake motor can achieve accurate rotation control, can accurately stop the rotation of the turntable 121, and can restart within a predetermined time interval.

[0040] See also Figure 2 In another specific embodiment, the driving device 150 further includes a brake pad 156 and a brake member 157 that rotate synchronously with the second rotating member 153. The brake member 157 is connected to the angle sensor 155 by signal. The brake member 157 has an electromagnet. When the electromagnet is energized, the brake member 157 can prevent the brake pad 156 from rotating. It can be understood that the setting of the brake pad 156 can quickly lock the position of the second rotating member 153 to prevent the rotating disk 121 from shaking before the stop state occurs, which affects the marking quality of the workpiece.

[0041] See also Figure 1 In another specific embodiment of the utility model, the first support assembly 130 includes a first displacement module 131 and a second displacement module 132. The laser emitting device 110 is fixedly mounted on the first displacement module 131, and the first displacement module 131 is mounted on the second displacement module 132. The first displacement module 131 is used for the laser emitting device 110 to move along the first direction V1, and the second displacement module 132 is used for the laser emitting device 110 to move along the second direction V2. It can be understood that the second displacement module 132 is used to adjust the distance between the laser emitting device 110 and the workpiece, and the first displacement module 131 is used to adjust the position of the laser emitting device 110 relative to the workpiece in the left and right directions.

[0042] Optionally, both the first displacement module 131 and the second displacement module 132 are screw-slider displacement modules.

[0043] Optionally, the first supporting assembly 130 further includes a third displacement module 133, and the third displacement module 133 is used to adjust the position of the laser emitting device 110 relative to the workpiece in the up and down directions.

[0044] It should also be noted that if Figure 1 As shown, the first displacement module 131 can drive the laser emitting device 110 to move in the second direction V2; the second displacement module 132 can drive the laser emitting device 110 to move in the first direction V1; and the third displacement module 133 can drive the laser emitting device 110 to move in the third direction V3.

[0045] Furthermore, the laser marking machine 100 further includes a base 161 and a back plate 162, the first support assembly 130 and the second displacement module 132 are mounted on the base 161, and the back plate 162 is located in the marking direction of the laser emitting device 110 and connected to the base 161. The worker's operating area is arranged opposite to the back plate 162.

[0046] like Figure 2 As shown, in one embodiment, the laser marking machine 100 further includes a residue collection frame 170, which is located on the base 161 and movably connected to the base 161. The residue collection frame 170 is used to collect residues dropped during the printing process of the workpiece.

[0047] like Figure 1 As shown, in one embodiment, the laser marking machine 100 includes a suction assembly 180, which is disposed on the back plate 162 and close to the marking direction of the laser emitting device 110, for removing smoke and dust generated during laser processing of the workpiece surface.

[0048] As described above, the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
