Description

Technical Field

[0001] This utility model relates to the field of engraving equipment technology, and more specifically to a laser engraving equipment for shoe sole patterns. Background Technology

[0002] Existing laser engraving equipment for shoe sole patterns mostly uses fixed-angle laser engraving equipment. The laser emission direction is singular and cannot be flexibly adjusted according to the curvature of the shoe sole surface and the depth of the pattern, resulting in insufficient engraving precision. In addition, the laser lens is easily contaminated by dust during the processing, affecting the laser transmission quality and service life. At the same time, some equipment has a complex structure, is difficult to adjust and maintain, and has low overall reliability.

[0003] Existing shoe sole engraving equipment, such as the patent application number CN209047505U, "A Novel Shoe Sole Engraving Pattern Processing Equipment," uses a shoe sole clamp on a fixed platform and a laser engraving component directly above it to achieve laser processing of shoe sole patterns. The structure is relatively simple and can be used with a robotic arm and clamping mechanism to complete loading and drying. However, its optical path adjustment mainly relies on the movement of the robotic arm, the laser emission angle is not precisely adjustable, and there is no protective lens component for easy maintenance. Optical dust prevention and lens replacement are inconvenient, making it difficult to achieve stable and high-precision multi-angle engraving for complex curved patterns. Utility Model Content

Detailed Implementation Example 1

[0015] like Figures 1 to 4As shown, this utility model proposes a laser engraving device for shoe sole patterns, including a frame 3, an operating table 4, a laser 2, and a corner mechanism 1 for adjusting the laser emission direction; the frame 3 adopts a portal frame structure, is made entirely of metal profiles, and its bottom is fixedly connected to the operating table 4 to form a stable support frame; the laser 2 is installed below the crossbeam of the frame 3, and its emission end is opposite to the entrance window 14 of the corner mechanism 1, for projecting the laser beam vertically into the interior of the corner mechanism 1; the laser 2 is preferably a CO2 laser 2, which has stable output power and can meet the engraving processing requirements of various shoe sole materials such as rubber, EVA, and TPU.

[0016] The operating table 4 is located in the middle area at the bottom of the frame 3. The table surface is a flat and smooth metal working surface, which is used to place the shoe sole workpiece to be engraved. The operating table 4 can be used with positioning fixtures as needed to fix shoe soles of different specifications and ensure processing accuracy.

[0017] The corner mechanism 1 is installed above the operating table 4 and is fixedly connected to the frame 3 through the side wall connecting column 13, so that the corner mechanism 1 is on the laser beam transmission path; the corner mechanism 1 is a rectangular shell structure, with a protective mirror assembly 11 in the middle of the interior and a reflection mechanism 12 in the bottom side plate 15.

[0018] The protective lens assembly 11 includes a pull plate 111, a locking button 112, a connecting plate 114, and a protective window 113. The pull plate 111 is installed on the outer side of the middle part of the housing of the corner mechanism 1 via a hinge and can be flipped open along the surface of the housing. The connecting plate 114 is vertically connected to the pull plate 111, and the protective window 113 is fixed on the connecting plate 114 and located on the laser incident light path. The protective window 113 is preferably made of ZnSe material, which has high transmittance and heat resistance, and can effectively prevent laser energy loss and dust contamination. The locking button 112 is located on the outer side of the pull plate 111 and is used to lock and fix the protective lens assembly 11 when it is closed to prevent vibration and loosening during processing. With the above structure, the protective lens assembly 11 can be opened without disassembling the corner mechanism 1, which facilitates cleaning or replacement of the protective window 113 and ensures the cleanliness of the light path.

[0019] The reflecting mechanism 12 is located inside the bottom side plate 15 of the corner mechanism 1, and includes a knob 121, a rotating plate 122, a rotating shaft 123, and a reflector 124. The reflector 124 is installed at the front end of the rotating plate 122, and the rotating plate 122 is fixedly connected to the rotating shaft 123. The knob 121 is located outside the side wall of the corner mechanism 1. The knob 121 drives the rotating shaft 123 to rotate, thereby driving the reflector 124 to rotate synchronously, so as to realize the continuous adjustment of the laser reflection angle. The reflector 124 is preferably a solid Mo mirror with a high reflectivity coating on its surface, which can effectively reflect CO2 laser. The outer surface of the knob 121 is provided with anti-slip texture for easy manual operation, and the reflection angle can be precisely fixed through the threaded locking structure. The tilt angle adjustment range of the reflector 124 is 0 to 90 degrees, which can flexibly adjust the laser emission direction according to the height of the sole surface and the engraving depth, so that the laser beam irradiates the sole surface at the optimal angle.

[0020] During operation, the laser beam emitted by the laser 2 enters the corner mechanism 1 through the entrance window 14, passes through the protective window 113 of the protective mirror assembly 11, and reaches the reflection mechanism 12. The operator adjusts the angle of the reflector 124 by the knob 121 according to the engraving position and texture depth of the sole, so that the laser beam is reflected and projected onto the sole surface, thereby realizing the engraving of textures in different directions, depths and shapes. After the engraving is completed, the protective mirror assembly 11 can be opened for lens cleaning to prevent dust accumulation from affecting the light path.

[0021] The structural design of this utility model makes the laser optical path closed and stable, preventing impurities from entering the optical channel and extending the life of optical components; through the adjustable structure of the reflector 124, the laser emission angle can be flexibly controlled, enabling multi-angle engraving operations for different shoe sole patterns, improving engraving accuracy and efficiency.
