[0027] Example

[0028] like Figures 1 to 4 As shown, a dust collection port device for laser processing includes a dust collection outer cover 1. A mounting plate 2 is connected to the upper end of the dust collection outer cover 1. A dust collection inner core tube 24 is connected to the mounting plate 2. The dust collection inner core tube 24 is located at the center of the inner cavity of the dust collection outer cover 1. A dust collection gap is provided between the outer wall of the dust collection inner core tube 24 and the inner wall of the dust collection outer cover 1. An optical lens 21 is connected between the dust collection inner core tube 24 and the mounting plate 2. A drain pipe connector 25, communicating with the dust collection inner core tube, is connected to the outer wall of the dust collection inner core tube 24. A lower air knife blowing block 3 is connected to the lower end of the dust collection outer cover 1. The lower air knife blowing block 3 has a dust collection through hole that communicates with the dust collection distance. The lower end of the dust collection inner core tube 24 extends into the dust collection through hole and is flush with the bottom of the lower air knife blowing block 3. The bottom of the lower air knife blowing block 3 has a lower air knife blowing groove 33 that communicates with the dust collection through hole. The outer side of the lower air knife blowing block 3 is connected to a lower air knife pipe connector 32 that communicates with the lower air knife blowing groove 33. The side of the dust collection outer cover 1 is connected to a dust extraction pipe 12 that communicates with the dust collection outer cover 1. The outer side of the dust collection outer cover 1 is connected to a bent pipe connector 16 that communicates with the dust collection outer cover 1.

[0029] In Example 1

[0030] Based on the embodiment, optical lenses can be protected, and the shielding airflow of the upper air knife effectively reduces the adhesion of a small amount of rising dust to the optical lenses. The specific structure is as follows: an upper air knife cover plate 22 is connected between the dust collection inner tube 24 and the mounting plate 2. A lens groove for placing the optical lens 21 is opened in the center of the upper air knife cover plate 22. A circular shielding groove 26 for shielding the dust of the optical lens is opened at the upper end of the dust collection inner tube 24. A shielding channel communicating with the dust collection inner tube 24 is provided between the bottom of the upper air knife cover plate 22 and the circular shielding groove 26. An upper air knife tube connector 23 communicating with the circular shielding groove 26 is connected to the outer wall of the dust collection inner tube 24.

[0031] Meanwhile, the mounting plate 2 located at the optical lens has a lens through hole, and the optical lens is fixed in the lens groove by the mounting plate 2, which facilitates installation.

[0032] The dust collection hood 1 has several dust collection ports, and the dust extraction pipe 12 is connected to the dust collection hood 1 through the dust collection ports. A sealing plate 11 is connected to each dust collection port. The installation position can be changed by using different dust collection ports, making it highly practical. The installation of the dust collection ports and the dust extraction pipe 12 can be adjusted according to the actual needs of the installed equipment. After one dust collection port is installed, the other dust collection ports are sealed by the sealing plate 11, achieving a semi-sealed structure for the dust collection hood.

[0033] In both the embodiment and the first embodiment, the dust collection cover 1 is connected to a threaded adapter 14, the bent pipe joint 16 is connected to the threaded adapter 14, and the threaded adapter 14 is connected to a T-shaped pipe joint 15 installed inside the dust collection cover.

[0034] In both the embodiment and embodiment one, the lower air knife blowing block 3 is provided with four lower air knife blowing grooves 33. The lower air knife blowing block 3 is connected to lower air knife pipe connectors 32 that correspond to and communicate with the four lower air knife blowing grooves 33. A lower air knife cover plate 31 is connected to the bottom of the lower air knife blowing block 3. A lower air knife channel communicating with a dust collection hole is provided between the lower air knife cover plate 31 and the lower air knife blowing grooves 33. The lower air knives at different positions can quickly blow away dust and other particles from the surrounding area.

[0035] In both the embodiment and the first embodiment, the dust collection inner core tube 24 connected to the drainage pipe connector 25 is provided with a drainage hole. The drainage hole has an inclined structure, which allows for downward airflow.

[0036] The working principle of this invention is as follows:

[0037] like Figure 5 As shown, in specific work, such as Figure 1 The installation relationship is to assemble the dust collection port to form an annular closed space. The dust collection port is close to the surface of the object being processed. Then, the dust collection fan connected to the dust collection pipe is turned on. At the same time, gas with a specified flow rate and pressure is introduced into the upper air knife pipe joint, the diversion pipe joint, and the four lower air knife pipe joints 32 (the flow rate and pressure can be adjusted by those skilled in the art and can be increased or decreased according to actual requirements). At this time, the airflow A ejected from the gap (shielding channel) formed by the upper air knife cover plate 22 and the dust collection core 24 forms an air shield layer to reduce the pollution of the optical lens 21 by rising dust. The airflow B ejected from the diversion pipe joint 25 guides the airflow to sink and form a mixed airflow C, which is divided into airflow D1 and D2 on the surface of the object. The airflow E1 and E2 ejected from the gap (lower air knife channel) formed by the lower air knife blowing block 3 and the lower air knife cover plate 31 are led to point F by the negative pressure of the dust collection fan, thereby collecting the smoke, small particles, etc. generated by laser processing and sending them to the processing device for processing through the dust collection pipe.

[0038] This invention is applicable to the processing of flat products. It features a simple and compact structure, and works best when used with a high-powered dust collection fan. It can be used close to the object surface, effectively reducing the possibility of dust escape. This invention adds an optical lens and an upper air knife connector for dust removal, effectively preventing a small amount of rising dust from adhering to the laser lens without affecting the laser processing effect. The shielded airflow of the upper air knife further reduces the adhesion of rising dust to the optical lens, lowering the wear and tear costs of the laser lens. This invention is easily automated, provides excellent dust collection, improves production efficiency, and saves costs.

[0039] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0040] In the description of this application, it should be noted that the terms "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0041] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or vertical, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0042] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
