Description

Technical Field

[0001] This utility model relates to the field of laser engraving machine technology, and in particular to a positioning mechanism for a laser engraving machine. Background Technology

[0002] A laser engraving machine is a device that uses laser technology for marking, primarily used for marking and engraving on the surfaces of various materials. Its working principle is to use the high temperature generated by the laser beam to ablate the material surface, thereby leaving a mark or engraving a pattern. Laser engraving machines can be divided into several types, including laser stamping machines, laser lettering machines, and laser marking machines.

[0003] When processing materials using a laser engraving machine, the material needs to be manually picked up and placed on the operating table, and then positioned and fixed by a positioning mechanism. During this process, the material's position also needs to be manually adjusted to ensure precise alignment with the output end of the laser engraving machine. However, this entire process requires repeated manual comparisons to ensure accuracy, which is time-consuming and delays the processing schedule. Therefore, we propose a positioning mechanism for the laser engraving machine to solve these problems. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-4 A positioning mechanism for a laser engraving machine includes a support frame 1. Mounting seats 17 are provided at the bottom corners of the support frame 1. The mounting seats 17 are fixed to the support frame 1 by support legs 16. In actual use, bolts can be placed on the mounting seats 17 to fix the support frame 1 on the operating table of the laser engraving machine.

[0023] like Figure 1 and Figure 4 As shown, U-shaped frames 2 are provided on both sides of the support frame 1. The openings of the two U-shaped frames 2 are arranged opposite each other, and a pushing mechanism 3 is installed on the side of the two U-shaped frames 2 that is relatively far apart. The pushing mechanism 3 is fixed on the mounting frame 4, and the mounting frame 4 is fixed to the support frame 1. In actual use, the pushing mechanism 3 is one of an electric push rod, a pneumatic cylinder, or a hydraulic cylinder, which can drive the two U-shaped frames 2 to move closer or further apart.

[0024] Furthermore, a guide shaft 14 is provided parallel to the side of the pushing mechanism 3. One end of the guide shaft 14 is fixed to the U-shaped frame 2, and the other end of the guide shaft 14 slides through the mounting frame 4 to improve the movement stability of the U-shaped frame 2.

[0025] After bringing the two U-shaped frames 2 close together, the material to be processed placed between the U-shaped frames 2 can be clamped and fixed. A first drive sprocket 5 is provided at both ends of the inner side of the U-shaped frame 2. The end of the first drive sprocket 5 is rotatably connected to the inner wall of the U-shaped frame 2. A ring-shaped first pressure strip 6 is installed on the first drive sprocket 5 via a chain. The first pressure strip 6 is a rough-surfaced rubber strip. A drive motor 7 is installed on the end of one of the first drive sprockets 5 and is fixed to the U-shaped frame 2. Thus, the material to be processed placed between the two U-shaped frames 2 is pressed and fixed by the first pressure strip 6. Under the action of the drive motor 7, the first pressure strip 6 can be driven to move linearly along the length of the U-shaped frame 2, thereby adjusting the position of the material to be processed to improve positioning accuracy.

[0026] Furthermore, multiple first support sprockets 8 are provided inside the U-shaped frame 2. The first support sprockets 8 are located between two first drive sprockets 5, and the ends of the first support sprockets 8 are rotatably connected to the inner wall of the U-shaped frame 2. The first support sprockets 8 also mesh with the chain of the first pressure bar 6, which increases the force on the first pressure bar 6, allows the first pressure bar 6 to make full contact with the material to be processed, and improves the transmission effect of the first pressure bar 6 on the material to be processed.

[0027] Specifically, when adjusting the position of the material to be processed by the movement of the first pressure bar 6, the two pushing mechanisms 3 can also be controlled to achieve the same-direction movement of the two U-shaped frames 2, thereby providing more directional movement for the position adjustment of the material to be processed, so as to achieve more precise positioning operation.

[0028] It should be noted that when the material to be processed is placed between the two U-shaped frames 2, as the two U-shaped frames 2 move closer to the material to be processed, such as... Figure 2 and Figure 4 As shown, an L-shaped frame 9 is provided below the U-shaped frame 2. The top of the L-shaped frame 9 is fixed to the U-shaped frame 2. A strip groove 10 is provided on the bottom of the L-shaped frame 9, and the frontal projection of the strip groove 10 is located outside the U-shaped frame 2. A second drive sprocket 11 is provided at both ends of the strip groove 10. The end of the second drive sprocket 11 is rotatably connected to the inner wall of the strip groove 10. A ring-shaped second pressure bar 12 is installed on the second drive sprocket 11 by a chain, which allows the bottom side of the material to be processed to be placed on the second pressure bar 12, thereby providing upward support for the material to be processed, improving the strength of the material to be processed, and the transmission of the second pressure bar 12 will not affect the transmission effect of the first pressure bar 6 on the material to be processed.

[0029] Furthermore, a plurality of second support sprockets 13 are provided between the two second drive sprockets 11 at intervals. The ends of the second support sprockets 13 are rotatably connected to the inner wall of the strip groove 10, and the second support sprockets 13 mesh with the chain of the second pressure bar 12 to improve the support strength of the second pressure bar 12 for the material to be processed.

[0030] Furthermore, the mounting bracket 4 is L-shaped, and a reinforcing plate 15 is provided on the inner side of the mounting bracket 4. The side of the reinforcing plate 15 is fixed to the inner wall of the mounting bracket 4 to improve the support strength of the mounting bracket 4.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
