Description

Technical Field

[0001] The utility model belongs to the technical field of laser engraving processing, and specifically refers to a laser engraving device for processing notebook shells. Background Technique

[0002] Laser engraving, also known as laser carving or laser marking, is based on numerical control technology and uses laser as the processing medium. The processed material undergoes physical denaturation of instantaneous melting and gasification under the irradiation of laser engraving, enabling laser engraving to achieve the processing purpose. It is commonly used in the processing of notebook shells. The existing laser engraving devices for notebook shell processing, such as a laser engraving device for notebook shell processing disclosed in the application number CN202323039532.X, are equipped with a sliding device that facilitates the tightening structure and is used in conjunction with a cooling unit to shorten the cooling waiting time, improve safety, and utilize a limiting mechanism to facilitate avoiding the risks of falling and scalding caused by excessive displacement, and can improve the heat dissipation efficiency.

[0003] However, in actual use, the existing laser engraving devices in the prior art cannot achieve continuous automatic processing during the processing. After the laser engraving is completed and the heat dissipation is over, the notebook shell needs to be removed from the sliding seat and the sliding seat needs to be reset before the next step of work can be carried out. The operation steps are cumbersome, the efficiency is low, it is not convenient to achieve mass production and processing, and the open structure generates dust during the laser engraving process. Long-term inhalation will cause harm to the human body and is not conducive to maintaining the environment. Therefore, we propose a laser engraving device for notebook shell processing to solve the above problems. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figure 1 , Figure 2 , Figure 3 , Figure 4 shown, a laser engraving device for processing a notebook housing proposed by the present invention includes a workbench 1, guiding side plates 2, and a bottom protection plate 3.

A conveyor belt 12 is provided on the conveying rollers 11, and the inner side of the conveyor belt 12 is slidably connected between the upper and lower ends of the guiding side plate 2. A double-output motor 13 is provided inside the side protection plate 10, and the output shaft of the double-output motor 13 is connected to the conveying roller 11.

[0024] In order to facilitate the rotation of the notebook housing for processing, the rotating mechanism 4 includes a rotating base 14, a driving motor 15, a driving gear 16, and a driven gear 17. The rotating base 14 is rotatably connected to the bottom inside the bottom protection plate 3. The driving motor 15 is arranged at the bottom of the bottom protection plate 3 and on one side of the rotating base 14. The driving gear 16 is arranged on the output shaft of the driving motor 15. The driven gear 17 is fixed to the top of the rotating base 14 and meshes with the driving gear 16. The electric push rod 5 is vertically fixed to the middle of the upper end of the rotating base 14 and penetrates through the driving gear 16.

[0025] In order to fix the notebook housing, the clamping and fixing mechanism 7 includes a clamping rod 18, a fixed clamping plate 19, and a connecting rod 20. The clamping rod 18 is rotatably connected to the side wall of the electric push rod 5. The fixed clamping plate 19 is fixed to the movable end of the clamping rod 18 and arranged on both sides of the lifting platform 6. One end of the connecting rod 20 is rotatably connected to the side wall of the output end of the electric push rod 5, and the other end of the connecting rod 20 is rotatably connected to the inner wall of the clamping rod 18.

[0026] In order to collect the soot generated during the laser engraving process, the dust removal mechanism 9 includes a dust collection hood 21, a dust storage box 22, a dust conveying pipe 23, an intake fan 24 and a dust suction fan 25. The dust collection hood 21 is fixed on the side wall of the bracket 8 and communicates with the inside of the bracket 8. The dust storage box 22 is fixed on the side wall of the bottom guard plate 3 and is arranged below the workbench 1. The dust conveying pipe 23 is connected between the dust storage box 22 and the dust collection hood 21. The intake fan 24 is arranged on the side wall of the bracket 8 and is symmetrically arranged with the dust collection hood 21. The dust suction fan 25 is arranged inside the dust collection hood 21.

[0027] As Figure 1 and Figure 3 shown, a laser box 26 is provided at the top of the bracket 8. A linear motor 27 is provided at the top inside the bracket 8. A slide table 28 is slidably connected to the linear motor 27. A laser head 29 is provided at the bottom of the slide table 28, and the laser head 29 is connected to the laser box 26.

[0028] As Figure 2 , Figure 3 and Figure 4 shown, the electric push rod 5 is vertically arranged with respect to the workbench 1. The lifting platform 6 is arranged between the electric push rod 5 and the bracket 8. The guiding side plate 2 is arranged between the bracket 8 and the workbench 1. The bottom guard plate 3 is arranged in a U shape. The bracket 8 is arranged in a hollow cuboid shape. The guiding side plate 2 is arranged in a cuboid shape with circular grooves on both sides. The clamping rod 18 is arranged in an L shape.

[0029] During specific use, the double-output motor 13 drives the conveying rollers 11 to rotate, causing the conveyor belt 12 thereon to rotate under the support of the guiding side plates 2, thereby conveying the notebook shell from one side of the bracket 8 to the other side. When the notebook shell on the conveyor belt 12 enters the bracket 8 and is under the laser head 29, the electric push rod 5 extends upward, causing the lifting platform 6 to rise and lift the notebook shell. At the same time, as the output end of the electric push rod 5 rises, the connecting rod 20 pulls the clamping rod 18 to rotate towards the middle lifting platform 6. Thus, after moving to the extreme position, the fixed clamping plate 19 at the upper end of the clamping rod 18 clamps the notebook shell on the lifting platform 6, and then the laser box 26 can be opened to use the laser head 29 to perform laser engraving processing on the notebook shell. During the processing, the dust suction fan 25 and the intake fan 24 are turned on. The intake fan 24 sends external air into the bracket 8, and the dust suction fan 25 on one side of the dust collection hood 21 sucks the smoke and dust generated during processing into the dust conveying pipe 23 and sends it into the dust storage box 22 for storage. At the same time, the heat generated by the laser engraving processing at the upper end of the notebook shell is taken away by the air flow in the bracket 8, achieving a heat dissipation effect. After the processing is completed, the electric push rod 5 retracts downward, and the notebook shell falls back onto the conveyor belt 12 and can be sent out to complete the processing. Through the above steps, continuous processing of the notebook shell can be achieved. When it is necessary to rotate the notebook shell, just turn on the drive motor 15 to drive the driving gear 16 to rotate, and the driven gear 17 meshing with the driving gear 16 drives the rotating base 14 to rotate. The above is the entire usage process of the laser engraving device for notebook shell processing.

[0030] The above describes the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the creative concept of the present invention, design structurally similar ways and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
