Description

Technical Field

[0001] This utility model relates to the field of engraving device technology, specifically a laser engraving device for plastic panels with a positioning structure. Background Technology

[0002] With the rapid development of consumer electronics, automotive electronics, medical devices and other fields, the annual growth rate of demand for laser engraving of ultra-thin (<15-10mm) and irregularly shaped plastic panels has reached 25%. Traditional mechanical engraving is prone to stress cracks due to contact processing, while laser engraving has become the mainstream technology due to its non-contact and high-precision advantages.

[0003] Traditional fixtures rely on manual adjustment and lack a two-way dynamic positioning mechanism, resulting in poor adaptability to changes in thickness and making them prone to offset errors. They cannot meet the requirements of plastic panels of different sizes and specifications. At the same time, plastic particles generated by laser cutting are prone to adhering to the surface of the laser head, causing energy attenuation. High-temperature debris may burn the panel surface, increasing the defect rate. In addition, the debris from thick plates is not completely removed, affecting the aesthetics of the process. Therefore, it is necessary to design a laser engraving device for plastic panels with a positioning structure. Summary of the Invention

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] Example 1:

[0024] Traditional laser engraving equipment for processing plastic panels suffers from several drawbacks. Firstly, it lacks a bidirectional dynamic positioning mechanism, leading to misalignment errors and the adhesion of tiny plastic particles from laser cutting to the laser head surface, causing energy attenuation. Additionally, high-temperature debris can burn the panel surface. Therefore, this invention provides a preferred embodiment of a laser engraving device for plastic panels with a positioning structure. Figure 1-4As shown: A laser engraving device for plastic panels with a positioning structure includes a laser base 1, a connecting arm 2 fixedly mounted on the outer wall of the laser base 1, a control display screen 3 fixedly mounted on the top of the connecting arm 2, a mounting long seat 4 fixedly mounted on the top of the laser base 1, a mounting groove formed on the top of the mounting long seat 4, and an adjusting vertical rail 41 fixedly mounted on the bottom of the inner wall of the mounting groove. A wide arched support frame 5 is slidably connected to the outer wall of the adjusting vertical rail 41, and an adjusting horizontal rail 51 is fixedly mounted on the top of the wide arched support frame 5. A connecting seat is slidably connected to the outer wall of 51, and a laser seat 6 is fixedly installed on the top of the connecting seat. A laser head 7 is provided at the bottom of the laser seat 6. A positioning air blowing assembly 8 is provided above and outside the laser base 1. The positioning air blowing assembly 8 includes: a guide positioning part 81, which is provided above and inside the laser base 1; and an adjusting air blowing part 82, which is provided above and outside the laser base 1, and is provided outside the guide positioning part 81.

[0025] The guide positioning part 81 includes: a thin arched support frame 811, which is fixedly installed on the top of the laser base 1; an alignment sliding hole 819, which is opened on the top of the laser base 1, and there are two sets of the alignment sliding hole 819 arranged symmetrically; a sliding hole 812 is opened on the top of the thin arched support frame 811, and there are two sets of the sliding hole 812 arranged symmetrically; a sliding hole 813 is provided below the sliding hole 812, and the sliding hole 813 is opened on the top of the laser base 1; the sliding hole 812 and the sliding hole 813 are compatible; a slider is slidably connected inside the sliding hole 812 and the sliding hole 813; and a connecting C-shaped sliding plate 814 is fixedly installed between the sliders, and there are two sets of the connecting C-shaped sliding plate 814 arranged symmetrically.

[0026] Springs 815 are evenly and uniformly fixedly installed on the inner side wall of the C-shaped slide plate 814. A limit guide plate 816 is fixedly installed on the other end of the springs 815. A cylinder 817 is fixedly installed on the top of the thin arch support frame 811. A connecting block 818 is fixedly installed on the connecting end of the cylinder 817 through a connecting rod.

[0027] A second cylinder 8110 is provided above the alignment sliding hole 819, and the second cylinder 8110 is fixedly installed on the top of the laser base 1. The connecting end of the second cylinder 8110 is fixedly installed with a connecting long slide plate 8111 through a connecting column, and the connecting long slide plate 8111 is slidably connected to the alignment sliding hole 819. The outer wall of the connecting long slide plate 8111 has vertical holes 8112, and there are two sets in total.

[0028] A second spring 8113 is fixedly installed on the bottom of the inner wall of the vertical hole 8112.

A positioning clamping plate 8115 is fixedly installed on the inner wall of the sliding frame 8114. A small cylinder 8116 is fixedly installed on the top of the connecting long slide plate 8111. The connecting end of the small cylinder 8116 is fixedly connected to the top of the positioning clamping plate 8115 through a connecting rod.

[0029] Furthermore, in this embodiment, a cylinder 817 drives a connecting block 818 to move a slider in sliding holes 812 and 813, thereby adjusting the spacing of the guide plate 816 to accommodate the centering of plastic panels of different widths. At the same time, a cylinder 8110 pushes a connecting slide plate 8111 to slide along an aligned sliding hole 819, which, together with a small cylinder 8116, drives the positioning clamping plate 8115 to rise and fall, forming a dual constraint of slide rail and elastic clamping. With the help of springs 815 and 8113, the small vibrations generated during laser processing are absorbed.

[0030] Example 2:

[0031] Please see Figures 1-4 Furthermore, based on Embodiment 1, the following is further obtained: the adjustable blowing part 82 includes: a mounting plate seat 821, which is fixedly installed on the top of the laser base 1, and there are two sets of the mounting plate seat 821 located inside the mounting plate seat 4; a blower 829, which is fixedly installed on the outer wall of the laser base 1 through a support plate; a small motor 822 is provided behind the mounting plate seat 821, and the small motor 822 is fixedly installed on the top of the laser base 1. A sliding groove is provided on the top of the mounting plate seat 821. An adjusting screw 823 is provided at the output end of the small motor 822 through a coupling. The adjusting screw 823 moves through the rear of the mounting plate seat 821 and extends to the inner wall of the sliding groove. A connecting arc frame 824 is slidably connected to the outer wall of the adjusting screw 823.

[0032] The bottom of the connecting arc frame 824 is provided with an installation groove, and an air blowing connecting shell 825 is fixedly installed on the inner wall of the installation groove. An air blowing hole 826 is provided at the bottom of the air blowing connecting shell 825. An air blowing pipe 827 is fixedly installed inside the air blowing connecting shell 825, and the air blowing pipe 827 extends to one side of the outer wall of the connecting arc frame 824. An air blowing hole 828 is provided at the bottom of the air blowing pipe 827, and the air blowing hole 828 is compatible with the air blowing hole 826.

[0033] The blower 829 has a connecting flexible hose 8210 connected to its connection port. The other end of the connecting flexible hose 8210 is connected to the inside of the air blowing pipe 827. The connecting flexible hose 8210 and the outer wall of the air blowing pipe 827 are fitted with a connecting sleeve 8211.

[0034] Furthermore, in this embodiment, a small motor 822 drives an adjusting screw 823 to move the air blowing connecting shell 825 synchronously with the laser head 7, ensuring that the first air blowing hole 826 and the second air blowing hole 828 are always aligned within 5-10mm in front of the processing area. In conjunction with the blower 829 and the connecting telescopic hose 8210, it can adapt to the airflow requirements of different processing depths. At the same time, the second air blowing hole 828 is tilted downward at 45° to form a spiral airflow field, which effectively removes processing debris and guides the smoke generated by laser burning to the dust collection part.

[0035] In use, firstly, cylinder 817 is in the retracted state, and connecting block 818 drives slider to the bottom of sliding hole 812. Limiting guide plate 816 maintains its maximum spacing under the action of spring 815. Then, cylinder 8110 retracts, and positioning clamping plate 8115 is at its lowest position under the action of spring 8113. Next, the plastic panel is placed on top of laser base 1, and cylinder 817 is activated to push connecting block 818 upwards. This causes slider to drive connecting C-shaped sliding plate 814 to move synchronously, and limiting guide plate 816 retracts inwards to the preset spacing, achieving lateral positioning of the panel.

[0036] Furthermore, the second cylinder 8110 pushes the connecting long slide plate 8111 to slide along the aligned sliding hole 819, and the small cylinder 8116 simultaneously pushes the positioning clamping plate 8115 to rise. The flexible clamping is achieved by the second spring 8113 in the vertical hole 8112, thus completing the longitudinal positioning of the panel.

[0037] Furthermore, after the blower 829 is started, the airflow is delivered to the air blowing pipe 827 through the connecting telescopic hose 8210, forming an initial airflow at the second air blowing hole 828. The small motor 822 drives the adjusting screw 823 to rotate, causing the connecting arc frame 824 to move along the slide groove, and the blowing angle is adjusted through the first air blowing hole 826 of the air blowing connecting shell 825. When the laser head 7 moves, the connecting telescopic hose 8210 automatically extends and retracts to maintain a stable airflow.

[0038] Furthermore, during the engraving process, the airflow field formed by air hole 1 826 and air hole 2 828 continuously removes debris from the panel surface, while airflow cooling suppresses the smoke generated by laser burning, protecting the optical components of the laser head 7.

[0039] By inputting parameters such as engraving path and power into the control display screen 3, the system calculates the movement trajectory of the laser head 7. When the laser head 7 moves along the preset path, the guide positioning part 81 keeps the panel fixed, the air blowing part 82 adjusts the air blowing position in real time according to the position of the laser head 7, and the blower 829 provides a continuous airflow, forming a protective airflow layer through the first air blowing hole 826 and the second air blowing hole 828.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
