Description

Technical Field

[0001] This utility model relates to the field of laser oscillating head technology, and in particular to a WOB laser oscillating head with a double protective lens structure. Background Technology

[0002] Laser cutting and welding technologies currently offer advantages such as narrow kerfs, high precision, and no contact stress, leading to their widespread application in industrial production. During laser processing, the laser beam needs to be shaped and focused using collimating and focusing lenses. However, molten metal droplets, dust, and impurities from the cutting gas generated during processing can easily adhere to the lens surface. This not only affects the lens's light transmittance, causing laser energy attenuation, but can also lead to excessively high lens temperatures due to heat accumulation, potentially burning out the lens and consequently impacting processing quality and equipment operation.

[0003] Traditional laser oscillating heads typically use a single-layer protective lens. When replacing the protective lens, the focusing lens is exposed to the surrounding environment for an extended period, increasing the risk of contamination. Furthermore, some single-protective-lens structures have poor sealing performance; the sealing strip is prone to wear after prolonged use, leading to decreased sealing performance and reducing the effectiveness of the protective lens. Utility Model Content

[0004] The purpose of this invention is to provide a WOB laser swing head with a dual protective lens structure, which solves the problems of poor sealing and dust prevention, easy contamination of focusing lenses, and high maintenance costs in the aforementioned background technology.

[0005] To achieve the above objectives, a WOB laser swing head with a dual-protection lens structure is provided, comprising: a protective lens cavity, an outer protective lens component, a hand-tightening screw, a ferrule seal, a protective lens, a Teflon seal, and an inner protective lens component. The outer protective lens component, hand-tightening screw, ferrule seal, protective lens, Teflon seal, and inner protective lens component are each provided in two sets. The lower surface of the ferrule seal is attached to the upper surface of the protective lens. The protective lens is installed in the inner protective lens component. The Teflon seal is installed inside the lower surface of the inner protective lens component. The hand-tightening screw is installed inside the protective lens cavity.

[0006] According to the WOB laser swing head with a dual protective lens structure, the front end of the hand-tightening screw is threadedly connected to the inside of the protective lens cavity.

[0007] According to the WOB laser swing head with a dual protective lens structure, the lower surface of the protective lens cavity is attached to the upper surface of the outer component of the protective lens.

[0008] According to the WOB laser swing head with a dual protective lens structure, the two outer protective lens components are fitted together, and the hand-tightened screw is fitted to the connection between the two adjacent protective lens cavities and the outer protective lens components.

[0009] The above-mentioned solution has the following beneficial effects: 1. This utility model comprises a protective lens cavity, an outer protective lens component, a hand-tightening screw, a plug sealing ring, a protective lens, a Teflon sealing ring, and an inner protective lens component, all working together. Furthermore, two sets of each component are provided. During cutting, this design prevents dust from the cutting gas itself from being carried into the gas path and potentially adhering to the protective lens. It also prevents splashed metal droplets and dust from easily adhering to the lower surface of the protective lens. The combination of the plug sealing ring and the Teflon sealing ring provides an effective seal, preventing external dust from easily entering and affecting the protective lens's performance, thus avoiding excessive lens temperature rise and poor cutting results.

[0010] 2. Generally, laser swing head focusing lenses use double protective lenses. When replacing the protective lenses, the focusing lenses will not be exposed to the surrounding environment for a long time, avoiding the risk of contamination of the focusing lenses and avoiding affecting the accuracy and quality of subsequent processing.

[0011] 3. By setting up a double-layer protective lens, it is easy to get contaminated, avoiding frequent replacements and not increasing consumable costs. Moreover, the equipment does not need to be shut down for maintenance frequently, which would affect production efficiency and avoid increasing the overall maintenance cost.

[0012] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0015] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0016] Reference Figure 1-4 This utility model embodiment discloses a WOB laser swing head with a double protective lens structure, comprising: a protective lens cavity 1, an outer protective lens component 2, a hand-tightening screw 3, a ferrule sealing ring 4, a protective lens 5, a Teflon sealing ring 6, and an inner protective lens component 7. The outer protective lens component 2, hand-tightening screw 3, ferrule sealing ring 4, protective lens 5, Teflon sealing ring 6, and inner protective lens component 7 are all provided in two sets. The ferrule sealing ring 4 and Teflon sealing ring 7 work together to effectively achieve a sealing effect. The double-layered protective lens 5 is less susceptible to contamination, avoiding frequent replacements and reducing consumable costs. The lower surface of the ferrule sealing ring 4 is attached to the upper surface of the protective lens 5. The protective lens 5 is installed in the inner protective lens component 7, the Teflon sealing ring 6 is installed inside the lower surface of the inner protective lens component 7, and the hand-tightening screw 3 is installed inside the protective lens cavity 1.

[0017] The front end of the hand-tightening screw 3 is threadedly connected to the inside of the protective mirror cavity 1. The lower surface of the protective mirror cavity 1 is attached to the upper surface of the protective mirror outer component 2. The two protective mirror outer components 2 are attached to each other. The hand-tightening screw 3 is attached to the connection between the two adjacent protective mirror cavities 1 and the protective mirror outer components 2.

[0018] Working principle: The structure allows for the replacement of the protective lens through a pull-in method. It mainly consists of two layers of protective lenses, each containing a D37*7mm protective lens 5. To replace the protective lens, first loosen the hand screw 3 from the protective lens cavity 1, then pull out the protective lens window, remove the sealing ring 4, insert the new protective lens into the slot of the protective lens inner component 2, reinstall the sealing ring 4, insert the protective lens into the protective lens cavity 1, and tighten the hand screw 3. Each protective lens is sealed at the top by a sealing ring 4, which is fixed by being recessed into the groove of the inner component 7 of the protective lens. When inserted into the protective lens cavity 1, it presses against the sealing ring 4 to achieve a sealing effect. It is sealed at the bottom by a Teflon sealing ring 6, which is also fixed by being recessed into the groove of the inner component 7 of the protective lens. When inserted into the protective lens cavity 1, the cavity presses against the Teflon sealing ring 6 to achieve a sealing effect, preventing dust from entering and greatly reducing the contamination of the focusing lens. The protective mirror opening consists of an outer protective mirror component 2 and an inner protective mirror component 7. The two components are fixed together by two M3 countersunk hexagonal screws. The two parts of the upper and lower protective mirrors are identical, except that the installation directions of the outer components of the upper and lower protective mirror openings are different. The screw holes of the outer components of the upper protective mirror opening are installed facing upwards, while the screw holes of the outer components of the lower protective mirror opening are installed facing downwards. The inner component 7 of the protective mirror is always facing upwards to prevent the protective mirror from falling off when the protective mirror opening is pulled out. The protective lens opening is designed as a drawer. When the bottom protective lens is contaminated or damaged, it can be replaced directly. When replacing the lens, because there is a second protective lens for sealing, the focusing lens above will not be easily contaminated, saving time and cost. After the protective lens opening is pushed in, it is locked by a hand screw.

[0019] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
