[0025] In order to make the utility model's purpose, features, and advantages more obvious and easy to understand, the following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the embodiments described below are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in 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] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0027] See also Figure 1 and Figure 2 As shown, the utility model designs a laser engraving device, which includes a workbench 10, a laser head 23 and an adjustment component. The workbench 10 supports a workpiece, the laser head 23 is arranged above the workpiece, and the adjustment component is connected to the laser head 23 for adjusting the distance between the laser head 23 and the workpiece.

[0028] Specifically, the adjustment component includes a Z-axis guide rail 20 , a connecting block 21 and a driver. The connecting block 21 is arranged on the Z-axis guide rail 20 and is connected to the laser head 23 and the driver. The driver is used to drive the connecting block 21 to slide along the Z-axis guide rail 20 .

[0029] Specifically, the adjustment component further includes a telescopic motor 22, a side of the telescopic motor 22 is connected to the connecting block 21, and an output end of the telescopic motor 22 is connected to the laser head 23 for driving the laser head 23 to move in a horizontal direction.

[0030] It should be noted that the driver of the utility model is a cylinder. When the cylinder is started, it drives the connection block 21 to slide up and down along the Z-axis guide rail 20, so that the laser head 23 connected to the connection block 21 can move up and down, thereby adjusting the vertical distance between the laser head 23 and the workpiece, which can ensure that the laser beam can act on the workpiece surface at the best distance. The telescopic motor 22 connects the connection block 21 and the laser head 23, and can drive the laser head 23 to make fine adjustments in the horizontal direction. This horizontal movement enables the laser head 23 to move slightly forward and backward without changing its vertical distance with the workpiece, so as to adapt to the laser engraving requirements of different areas on the workpiece surface. Compared with the prior art, the laser engraving spacing of the utility model can be adjusted, which can be applied to the laser engraving of workpieces of different specifications, and has high versatility. Of course, it should be noted that in actual applications, the adjustment of the spacing between the laser head 23 and the workpiece can also be achieved by other means, and the utility model does not limit this.

[0031] Specifically, the laser engraving device further includes a light source, which is arranged on both sides of the laser head 23 for illuminating the workpiece. Specifically, the light source includes a fixing block 30, a fixing rod 31 and a lamp assembly, the fixing block 30 is provided with an avoidance hole 33, the laser beam emitted by the laser head 23 reaches the workpiece through the avoidance hole 33, and the fixing rod 31 connects the lamp assembly and the fixing block 30.

[0032] Specifically, the lamp tube assembly includes a plurality of light strips 32 , and the plurality of light strips 32 are spaced apart and distributed on the fixing rod 31 .

[0033] When the light source of the utility model is started, each light strip 32 begins to emit light, providing sufficient illumination for the workpiece surface. This illumination can not only make the details of the workpiece surface more clearly visible, but also help the laser head 23 to more accurately identify and locate the area that needs laser engraving, thereby improving the accuracy of laser engraving. The fixed block 30 is provided with an avoidance hole 33, and the laser beam can pass through the light source part without hindrance and directly act on the workpiece surface to achieve the laser engraving effect.

[0034] Specifically, a conveying member 11 is provided on the workbench 10 , and the workpiece is placed on the conveying member 11 , and the conveying member 11 is used to convey the workpiece.

[0035] Specifically, the laser engraving device also includes a first baffle 14 and a second baffle 15 . The second baffle 15 is close to the conveying member 11 . The first baffle 14 is arranged on the conveying member 11 . The first baffle 14 pushes the workpiece to move toward the second baffle 15 so that the workpiece abuts the first baffle 14 and the second baffle 15 .

[0036] Specifically, the laser engraving device further includes a telescopic rod, which includes a telescopic portion and a fixed portion 13 . The fixed portion 13 is connected to the telescopic portion, and the telescopic portion is connected to the first baffle 14 .

[0037] Specifically, the laser engraving device further includes a positioning frame 12 , and the positioning frame 12 connects the workbench 10 and the fixing part 13 .

[0038] The conveying member 11 of the utility model includes a motor and a conveyor belt. When the motor is started, the conveyor belt is driven, and the conveyor belt drives the workpiece to move. When the workpiece moves to face the laser head 23, the motor is turned off, and the telescopic rod is started. The first baffle 14 is pushed by the telescopic rod, so that the workpiece is tightly abutted between the first baffle 14 and the second baffle 15, thereby preventing laser engraving errors caused by movement or shaking of the workpiece. The laser head 23 can perform laser engraving on the workpiece. The utility model can accurately control the distance between the first baffle 14 and the second baffle 15 by adjusting the length of the telescopic rod, so as to adapt to workpieces of different sizes and shapes, and has high versatility. Of course, it should be noted that in actual applications, other devices can also be used to replace the telescopic rod, and the utility model does not limit this.
