Description

Technical Field

[0001] This utility model belongs to the field of metal processing technology, and specifically relates to a laser drilling device for metal filter screens. Background Technology

[0002] A laser drilling device for metal filters is a device that uses laser technology to process precise holes in metal filters. It generates a high-energy-density laser beam, focuses it on the surface of the metal filter, and rapidly melts and vaporizes the metal material to form the desired holes. The device features high precision, high efficiency, and non-contact processing, and can meet the drilling needs of different metal filters. It is widely used in aerospace, automotive, electronics, medical and other fields.

[0003] However, during the laser drilling process, the high-energy laser beam acts on the metal filter, causing the material to melt and vaporize rapidly, inevitably generating a large amount of metal debris and harmful gases. However, existing laser drilling equipment lacks an effective real-time cleaning mechanism during operation, making it difficult to remove the debris and gases generated by each drilling in a timely manner. These residual debris may adhere to the vicinity of the drilling area, causing interference with the energy transmission and focusing of subsequent laser beams, resulting in inconsistent hole sizes and even hole distortion. This not only affects drilling efficiency but also reduces the overall processing quality and precision of the metal filter.

[0004] To address the aforementioned issues, this application proposes a laser drilling device for metal filters. Utility Model Content

[0025] In this embodiment, the laser drilling machine 1 mainly consists of a laser generating system, namely a laser that generates a laser beam, a power supply and control system, a beam transmission and focusing system, including optical lenses and galvanometer systems, a mechanical motion system, including a worktable, motion control device and fixture system, and a cooling system. These systems work together to achieve high-precision drilling of materials such as metal filter screens. At the same time, two filter plates 16 are used to block debris and gas respectively. The filter plates are made of a composite structure of stainless steel wire mesh and glass fiber filter paper. The controller 7 is a master control device that controls the starting, speed adjustment, braking and reversing of the motor by changing the wiring of the main circuit or control circuit and changing the resistance value in the circuit according to a predetermined sequence.

[0026] Specifically, a sealing ring 3 is fixedly connected to the upper surface of the collection box 2. The inner wall of the sealing ring 3 is fixedly connected to the outer surface of the telescopic hose 4. In this embodiment, the sealing ring 3 can seal the connection between the telescopic hose 4 and the collection box 2, thereby improving the sealing performance of the equipment connection.

[0027] Specifically, two limiting frames 5 are fixedly connected to the upper surface and right side of the laser drilling machine 1. Each limiting frame 5 is sleeved on the outside of the telescopic hose 4. In this embodiment, the limiting frame 5 can limit the telescopic hose 4 to the laser drilling machine 1, thereby improving the stability of the telescopic hose 4.

[0028] Specifically, each metal flexible tube 9 is fixedly connected to a fixing bracket 8 on its outer surface. The two fixing brackets 8 are fixedly connected to the front and back sides of the laser drilling machine 1 respectively on their side facing each other. In this embodiment, the metal flexible tube 9 can be fixed to the laser drilling machine 1 by the fixing bracket 8. At the same time, the metal flexible tube 9 can undergo plastic deformation under the action of external force, and can maintain its shape after bending. It also has a certain elasticity to resist slight external force interference and maintain its shape.

[0029] Specifically, a connecting plate 10 is fixedly connected to the left side of the collection box 2. The left side of the connecting plate 10 is fixedly connected to the right side of the laser drilling machine 1. In this embodiment, the connecting plate 10 can fix the collection box 2 to the laser drilling machine 1 and make the collection box 2 sturdy.

[0030] Specifically, a sealing door 11 is movably hinged to the right side of the collection box 2, and a viewing plate 14 is fixedly connected to the inner wall of the sealing door 11. In this embodiment, the sealing door 11 allows the collection box 2 to be opened or closed, and the viewing plate 14 allows for convenient observation of the interior of the collection box 2.

[0031] Specifically, a mounting plate 12 is fixedly connected to the right side of the sealed door 11, and a handle 13 is fixedly connected to the right side of the mounting plate 12. In this embodiment, the handle 13 can be fixed to the sealed door 11 through the mounting plate 12, and the sealed door 11 can be easily opened or closed using the handle 13.

[0032] Specifically, a support base 17 is fixedly connected to the upper surface of the exhaust pump 18, and the upper surface of the support base 17 is fixedly connected to the bottom surface of the collection box 2. In this embodiment, the exhaust pump 18 can be fixed to the collection box 2 through the support base 17, and the exhaust pump 18 can be used stably for exhaust.

[0033] The working principle and usage process of this utility model are as follows: First, connect the sealing door 11, exhaust pump 18, and controller 7 to the power supply. Simultaneously, connect the exhaust pump 18 to the controller 7 via a wire. Place the laser drilling machine 1 in a suitable position. When it is necessary to drill holes in the metal filter, place the material on the appropriate position on the laser drilling machine 1. Simultaneously, turn on the laser drilling machine 1 and the exhaust pump 18. The laser drilling machine 1 will drill holes in the metal filter. At the same time, the exhaust pump 18 will start operating, creating a negative pressure in the collection box 2. The debris and gas generated during the drilling process are sucked into the collection box 2 through two metal hoses 9, a three-way pipe 6, and a telescopic hose 4. When the airflow carrying debris and gas passes through the filter plate 16, the stainless steel wire mesh layer of the filter plate 16 first intercepts larger metal debris. The glass fiber filter paper layer further adsorbs tiny gas particles, achieving solid-gas separation and ensuring that the discharged gas meets clean standards. Due to the malleable and shape-fixed characteristics of the metal hose 9, the angle can be flexibly adjusted according to the drilling position, always maintaining an efficient exhaust path. The telescopic hose 4 can also extend and move in conjunction with the metal hose 9, ensuring that the entire exhaust system follows the working position changes of the laser drilling machine 1, continuously collecting the generated debris and gas in a timely manner. After the drilling work is completed, the laser drilling machine 1 and the exhaust pump 18 are turned off, the power is cut off through the controller 7, and the internal situation is observed through the viewing plate 14. If it is necessary to clean the debris in the collection box 2 and replace the filter plate 16, the sealing door 11 is opened through the handle 13, and the filter plate 16 on the sliding tray 15 is taken out for cleaning or replacement, ensuring the efficient operation of the device for the next use.

[0034] 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.
