Description

Technical Field

[0001] This utility model specifically relates to the field of laser engraving machine technology, and more specifically to a laser engraving machine with positioning function. Background Technology

[0002] A laser engraving machine is a device that uses a high-energy laser beam to precisely process the surface of materials. Through the high temperature and high energy characteristics of the laser, permanent marks, engraved patterns, or cutting marks are formed on the surface of the material. Its core principle is to use the focused energy of the laser to cause physical or chemical changes (such as melting, vaporization, discoloration, etc.) on the surface of the material, thereby achieving fine processing effects. As a device used for laser engraving on the surface of materials, the working stability of the laser engraving machine is crucial to the engraving accuracy.

[0003] However, in practice, it has been noted that because the materials being processed are relatively light, they are not stable when placed on the worktable. During the engraving process, slight movement of the material can cause deviations, affecting the precision and quality of the laser engraving. Furthermore, the materials need to be manually aligned when placed. To ensure the quality of the laser engraving, the placement of the materials needs to be strictly controlled, but manual alignment takes a long time, resulting in reduced efficiency. Also, because the distance between the laser head and the material is small, using a baffle for positioning can easily obstruct the normal movement of the laser head, affecting normal processing. Utility Model Content

[0004] The purpose of this invention is to provide a laser engraving machine with a positioning function. A height-adjustable positioning structure is provided around the processing position, allowing for rapid positioning of the material to be processed. When the laser engraving head moves, the positioning structure automatically descends to prevent interference with the normal operation of the laser engraving head. Furthermore, the negative pressure adsorption structure at the bottom prevents material movement during processing, thereby improving laser engraving accuracy and quality. This addresses the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A laser engraving machine with positioning function includes a worktable, a movable module above the worktable, and an acrylic plate fixedly connected to the worktable at one end of the movable module. Both the acrylic plate and the worktable have corresponding air intake holes arranged in a rectangular array. The bottom of the worktable is movably connected to a workpiece locator, and the other end of the workpiece locator extends to the top of the worktable through a through groove opened at the end of the worktable.

[0006] As a further technical solution of this utility model, the workpiece positioner includes L-shaped limiting plates arranged in a rectangular array. The L-shaped limiting plates are located at the corner of the acrylic plate, and the end of the L-shaped limiting plates extends through the worktable to the bottom of the worktable.

[0007] As a further technical solution of this utility model, the bottom of the workbench is provided with a movable base plate that is fixedly connected to the L-shaped limiting plate, and the side of the movable base plate is provided with a pin connecting rod that is movably connected to the workbench, and the end of the pin connecting rod away from the movable base plate is integrally provided with a trapezoidal slider. The top of the trapezoidal slider extends through the through groove to the top of the worktable, while the end of the pin connecting rod away from the trapezoidal slider is also provided with a limiting groove.

[0008] As a further technical solution of this utility model, the bottom of the movable base plate is fixedly connected to a pin seat, and the end of the pin seat is movably connected to a rotating roller corresponding to the pin connecting rod, and the bottom of the rotating roller is located inside the limiting groove.

[0009] As a further technical solution of this utility model, the bottom of the workbench is also fixedly connected with a sealing connection cover that communicates with the air intake hole, and the movable base plate is located below the sealing connection cover. A vacuum pump is also installed on the inner side of the frame, and the vacuum pump is connected to the inner side of the sealed connection cover through a pipe.

[0010] As a further technical solution of this utility model, the mobile module includes two symmetrically arranged mounting brackets, each of which is movably connected to an adjusting screw, and the mounting bracket is fixedly connected to the worktable.

[0011] As a further technical solution of this utility model, a linear module is provided between the two mounting brackets, and both ends of the linear module are threaded with adjusting screws. A movable slide is slidably connected to the side of the linear module, and a laser engraving device is fixedly connected to the other side of the movable slide.

[0012] As a further technical solution of this utility model, the linear module is also fixedly connected to an extension arm on the side away from the laser engraver, and a pressing roller is movably connected to the end of the extension arm, and the pressing roller is located on the side of the trapezoidal slider.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, the material to be processed is placed on an acrylic plate. At this time, the vacuum pump in the frame body adsorbs the air inside the sealed connection cover through the pipe, so that the inside of the sealed connection cover is negative pressure. Then, the material to be processed covering it is adsorbed through the air intake hole, which prevents the material from shifting during processing and thus improves the laser engraving accuracy of the material. 2. In this utility model, when placing materials, since the laser engraver is located above the trapezoidal slider, the pressing roller on the side of the laser engraver presses the trapezoidal slider, causing the other end of the pin connecting rod to push the moving base plate upward, so that the end of the L-shaped limiting plate moves above the acrylic plate, quickly positioning the material to be processed, shortening the positioning time when placing materials, improving positioning efficiency, and thus improving processing efficiency; 3. In this utility model, after the material is placed in the designated position, the moving module will drive the laser engraver to move. At this time, the extension arm will drive the pressing roller to move away from the top of the trapezoidal slider, and the moving base plate will move downward on the end of the pin connecting rod by its own gravity, thereby causing the end of the L-shaped limiting plate to move downward to the inside of the worktable, thus preventing the normal movement of the laser engraver.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-9 This utility model embodiment provides a laser engraving machine with positioning function, including a worktable 2, a movable module 4 above the worktable 2, and an acrylic plate 8 fixedly connected to the worktable 2 at one end of the movable module 4. Both the acrylic plate 8 and the worktable 2 are provided with corresponding air intake holes 10 in a rectangular array. The bottom of the worktable 2 is movably connected to a workpiece locator 9, and the other end of the workpiece locator 9 extends to the top of the worktable 2 through a through groove 12 opened at the end of the worktable 2. The workpiece positioner 9 includes L-shaped limiting plates 92 arranged in a rectangular array. The L-shaped limiting plates 92 are located at the corner of the acrylic plate 8, and the end of the L-shaped limiting plates 92 extends through the worktable 2 to the bottom of the worktable 2.

[0026] By adopting the above technical solution, the material to be processed is placed on the acrylic plate 8. At this time, the vacuum pump in the frame 1 adsorbs the air inside the sealing connection cover 11 through the pipeline, so that the inside of the sealing connection cover 11 forms a negative pressure. Then, the material to be processed covered on it is adsorbed through the air intake hole 10 to prevent the material from shifting during processing, thereby improving the laser engraving accuracy of the material.

[0027] More specifically, the bottom of the workbench 2 is provided with a movable base plate 91 that is fixedly connected to the L-shaped limiting plate 92, and the side of the movable base plate 91 is provided with a pin connecting rod 93 that is movably connected to the workbench 2, and the end of the pin connecting rod 93 away from the movable base plate 91 is integrally provided with a trapezoidal slider 94. The top of the trapezoidal slider 94 extends through the through groove 12 to the top of the worktable 2, while the end of the pin connecting rod 93 away from the trapezoidal slider 94 is also provided with a limiting groove 96.

[0028] Furthermore, the bottom of the movable base plate 91 is fixedly connected to a pin seat 95, and the end of the pin seat 95 is movably connected to a rotating roller 97 corresponding to the pin connecting rod 93, and the bottom of the rotating roller 97 is located inside the limiting groove 96.

[0029] By adopting the above technical solution, when placing the material, since the laser engraver 5 is located above the trapezoidal slider 94, the pressing roller 46 on the side of the laser engraver 5 presses the trapezoidal slider 94, causing the other end of the pin connecting rod 93 to push the moving base plate 91 upward, so that the end of the L-shaped limiting plate 92 moves above the acrylic plate 8, quickly positioning the material to be processed, shortening the positioning time when placing the material, improving positioning efficiency, and thus improving processing efficiency.

[0030] Furthermore, the bottom of the workbench 2 is also fixedly connected to a sealing connection cover 11 that communicates with the air intake hole 10, and the movable base plate 91 is located below the sealing connection cover 11. A vacuum pump is also installed on the inner side of the frame body 1, and the vacuum pump is connected to the inner side of the sealing connection cover 11 through a pipe.

[0031] Furthermore, the mobile module 4 includes two symmetrically arranged mounting brackets 41, each of which is movably connected to an adjusting screw 42, and the mounting bracket 41 is fixedly connected to the worktable 2.

[0032] More specifically, a linear module 43 is provided between the two mounting brackets 41, and both ends of the linear module 43 are threadedly engaged with the adjusting screw 42. Furthermore, a movable slide 44 is slidably connected to the side of the linear module 43, and a laser engraver 5 is fixedly connected to the other side of the movable slide 44.

[0033] Furthermore, the linear module 43 is also fixedly connected to an extension arm 45 on the side away from the laser engraver 5, and a pressing roller 46 is movably connected to the end of the extension arm 45, and the pressing roller 46 is located on the side of the trapezoidal slider 94.

[0034] By adopting the above technical solution, after the material is placed in the designated position, the moving module 4 will drive the laser engraver 5 to move. At this time, the extension arm 45 will drive the pressing roller 46 to move away from the top of the trapezoidal slider 94, and the moving base plate 91 will move downward on the end of the pin connecting rod 93 by its own gravity, thereby causing the end of the L-shaped limiting plate 92 to move downward to the inside of the worktable 2, thereby preventing the normal movement of the laser engraver 5.

[0035] Furthermore, a semi-open protective cover 3 is fixedly connected to the side of the workbench 2 to provide protection during processing, and the bottom of the workbench 2 is fixedly connected to the frame 1.

[0036] Furthermore, the trapezoidal slider 94 is inclined on the side near the pin connecting rod 93. When the pressing roller 46 moves to the side of the trapezoidal slider 94, the pressing roller 46 will apply downward pressure to the trapezoidal slider 94 along the inclined surface of the trapezoidal slider 94, thereby causing the trapezoidal slider 94 to move downward.

[0037] Furthermore, a servo motor is fixedly connected to the end of the mounting bracket 41, and the end of the servo motor is in transmission cooperation with the adjusting screw 42. The side of the frame body 1 is also provided with an auxiliary frame 6, and a control computer 7 is installed on the top of the auxiliary frame 6. The control computer 7 can control the servo motor to drive the adjusting screw 42 to rotate, thereby driving the laser engraver 5 to move along the X direction. It can also control the linear module 43 to drive the laser engraver 5 to move along the Y direction, thereby performing laser engraving processing.

[0038] The working principle of this utility model is as follows: First, the material to be processed is placed on the acrylic plate 8. Since the acrylic plate 8 has vertical L-shaped limiting plates 92 around its perimeter, the material can be quickly positioned. Simultaneously, the vacuum pump in the frame 1 draws air from the inside of the sealing cover 11 through a pipe, creating a negative pressure inside the sealing cover 11. Then, the material to be processed is drawn in and fixed through the suction hole 10, preventing displacement during processing. Next, the moving module 4 moves the laser engraving device 5. At this time, the extension arm 45 moves the pressing roller 46 from the trapezoidal slider 94. The base plate 91 moves downwards under its own weight, causing the end of the L-shaped limiting plate 92 to move downwards to the inside of the worktable 2, thus preventing the laser engraver 5 from moving normally. After laser engraving is completed, the extension arm 45 pushes the pressing roller 46 to press the trapezoidal slider 94 again, causing the trapezoidal slider 94 to move downwards. At this time, the other end of the pin connecting rod 93 pushes the base plate 91 upwards, causing the end of the L-shaped limiting plate 92 to move above the acrylic plate 8, quickly positioning the material to be processed next, thereby improving positioning efficiency and thus improving the laser engraving efficiency of the material to be processed.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
