Description

Technical Field

[0001] This application relates to the field of laser technology, and more specifically, to a laser. Background Technology

[0002] A laser is a device that can generate and emit a highly directional, monochromatic, and coherent beam of light, and is commonly used in industrial production, cutting, welding, and other fields.

[0003] In related technologies, lasers typically weigh over 50 kilograms, making them difficult for a single operator to lift directly. Furthermore, when lasers require inspection or maintenance, it is usually necessary to disassemble each component in sequence, inspect and repair them, and then reassemble them in sequence, making the operation quite cumbersome and complex. Utility Model Content

[0004] In order to at least address some of the shortcomings mentioned in the related technologies, this application provides a laser.

[0005] To achieve the above objectives, this application provides a laser, including a housing. Openings communicating with the outside are formed on two opposite end faces of the housing, and a sealing plate is detachably mounted at each opening. Both the housing and the sealing plate are made of plastic. Multiple electronic devices are disposed within the housing, and these electronic devices are arranged flat within the housing near the openings.

[0006] Furthermore, an optical fiber assembly is disposed within the housing, positioned at the center of the housing to divide the internal space of the housing into two independent receiving cavities. Each receiving cavity communicates with the opening, and multiple electronic devices are housed within the receiving cavity.

[0007] Furthermore, the electronic device includes two circuit boards, both of which are disposed within one of the receiving cavities, and a pump source is disposed between the two circuit boards, with a gap between the pump source and the circuit boards.

[0008] Furthermore, a heat sink is disposed within the receiving cavity where the circuit board is located, and the heat sink is attached to the optical fiber assembly. The pump source is disposed concurrently with the heat sink, and the circuit board is at least partially disposed concurrently with the heat sink.

[0009] Furthermore, the pump source integrates at least two optical pumps and at least one red light pump.

[0010] Furthermore, the housing is provided with an installation port that connects the inside and outside, and a pressure valve is sealed and installed at the installation port.

[0011] Furthermore, the outer surface of the housing is provided with a grip portion, which is a plastic handle, and the interior of the plastic handle has a cavity filled with a sheet metal bracket.

[0012] Furthermore, a sealing element is provided at the opening, and the sealing element is evenly distributed along the edge of the opening facing the sealing plate. When the sealing plate is installed at the opening, it compresses the sealing element to seal the gap between the opening and the sealing plate.

[0013] Furthermore, a bracket is also provided inside the housing. The bracket is disposed inside the housing and is attached to the inner wall of the housing to support the housing. The bracket is detachably assembled from multiple sheet metal parts.

[0014] Furthermore, a control unit is provided on the housing, which is electrically connected to the electronic device for operator control. The control unit includes a screen and is also provided with an interface for data communication with the screen. The interface is located at the opening and is blocked by the sealing plate.

[0015] Through the above technical solution, the laser of this application has a plastic housing, which reduces the overall weight of the laser, making it easier to handle, and effectively reduces production costs. Furthermore, since the electronic components of the laser of this application are all laid flat at the opening of the housing, when the laser needs inspection or maintenance, only the sealing plate needs to be removed, allowing the operator to directly and clearly see all the electronic components and perform inspection and maintenance without having to remove each component from the housing. This makes the maintenance and inspection process simple, convenient, and easy to operate.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0024] In the description of this application, it should be noted that the terms "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.

[0025] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" 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 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.

[0026] This application provides a laser to solve the problems in related technologies, such as the large overall weight of the laser, which makes it inconvenient to handle, move, and perform inspection and maintenance.

[0027] Please see Figures 1 to 3This embodiment provides a laser, including a housing 100. Openings 110 communicating with the outside are formed on two opposite end faces of the housing 100. A sealing plate 120 is detachably installed at each opening 110. Both the housing 100 and the sealing plate 120 are made of plastic. Multiple electronic devices 300 are disposed inside the housing 100, and these devices are arranged flatly inside the housing 100 near the openings 110.

[0028] Specifically, this embodiment uses plastic as the material for the housing 100, which significantly reduces the overall weight of the laser. This is especially important for applications requiring frequent relocation, making handling and installation easier and more convenient.

[0029] Typically, the housing of lasers in related technologies is made of metal and weighs over 50 kilograms. By making the housing 100 plastic, the weight can be reduced to about 20 kilograms, ensuring that a single operator can lift and move it normally.

[0030] After replacing the housing 100 with a plastic material, the requirements for mechanical strength, heat resistance, electrical insulation, and chemical stability of the housing 100, which serves as the laser, must be comprehensively considered. Polycarbonate, polyamide, and acrylonitrile-butadiene-styrene copolymer can be selected as the main materials for the housing 100. These plastics not only possess high strength and rigidity but also good impact resistance. Polycarbonate, in particular, also exhibits good heat resistance and flame retardancy. Of course, other plastics can also be selected according to actual needs, as long as the resulting housing 100 meets the requirements of the laser.

[0031] Structurally, all electronic components 300 are laid out flat near the opening 110, meaning that after opening the sealing plate 120, all components are immediately visible, and each electronic component 300 can be directly accessed without further disassembly. This greatly simplifies the inspection, debugging, and maintenance process. Since maintenance can be performed without disassembling the complex internal structure, downtime is significantly reduced, work efficiency is improved, and the risk of additional damage due to improper disassembly or assembly is minimized.

[0032] Furthermore, for technicians, such an easily accessible design reduces the skill requirements, allowing even non-experts to easily perform basic maintenance tasks, such as replacing parts or troubleshooting simple faults, thus further improving the versatility of this embodiment.

[0033] In one embodiment, exemplarily, such as Figures 1 to 3As shown, the bottom of the housing 100 is provided with support legs 150. Because the material of the housing 100 has been improved in this embodiment, the overall weight has been greatly reduced. Therefore, the support legs 150 support the laser, preventing it from directly contacting the ground and protecting it. Furthermore, compared to caster supports used in related technologies for easy movement, the support legs 150 in this embodiment, due to their smaller weight, do not affect the movement of the laser. The support legs 150 also ensure reliable support while preventing displacement of the laser during use, making the support more reliable.

[0034] In one embodiment, exemplarily, such as Figure 2 , Figure 3 As shown, an optical fiber assembly 200 is disposed inside the housing 100. The optical fiber assembly 200 is located in the middle of the housing 100 to divide the internal space of the housing 100 into two independent receiving cavities 210. The receiving cavity 210 communicates with the opening 110, and multiple electronic devices 300 are disposed inside the receiving cavity 210.

[0035] In this embodiment, the fiber optic assembly 200 includes a fiber optic disk and a disk cover. The fiber optic disk is used to house and organize the fiber optics for use by the laser, while the disk cover is disposed outside the fiber optic disk to protect it. By using the fiber optic assembly 200 as a physical barrier, the space within the housing 100 can be organized and allocated more effectively. This allows components with different functions to be optimally arranged in their respective spaces, avoiding mutual interference between components. The separate receiving cavities 210 can accommodate different functional modules as needed, such as one for housing the power supply 330 and another for housing the laser generator, circuit board 310, or other sensitive components, improving the overall system integration.

[0036] Furthermore, if an electronic component 300 in one of the housing cavities 210 malfunctions or generates heat, the fiber optic assembly 200 acts as an isolation layer, preventing these problems from directly affecting components in the other housing cavity 210. This reduces the risk of fault propagation and improves system stability. The independent housing cavities 210 also facilitate better thermal management. For example, targeted heat dissipation paths can be designed to ensure effective cooling of each area, preventing overheating from impacting equipment performance.

[0037] Furthermore, when a specific part needs to be inspected or repaired, all components of that part can be accessed simply by opening the corresponding sealing plate 120, without moving other unrelated parts. Moreover, when repairing the electronic device 300 in one of the accommodating cavities 210, the electronic device 300 in the other accommodating cavity 210 will not be affected. This design greatly simplifies the maintenance process and reduces downtime.

[0038] Please continue reading. Figures 1 to 3 For example, the electronic device 300 includes two circuit boards 310, each disposed within a receiving cavity 210. A pump source 320 is also disposed between the two circuit boards 310, with a gap between the pump source 320 and the circuit boards 310. The pump source 320, as the excitation source of the laser, generates heat during operation. By leaving a gap between the pump source 320 and the circuit boards 310, airflow can be promoted, aiding in heat dissipation. This helps maintain all components within a suitable operating temperature range, preventing performance degradation or damage due to overheating. The gap between the pump source 320 and the two circuit boards 310 also isolates the heat source to some extent, preventing direct thermal impact on the circuit boards 310, thereby protecting sensitive electronic components.

[0039] The clearance provides a degree of physical buffer for the pump source 320, reducing the risk of damage to the pump source 320 and its connection points caused by vibration or impact. This is especially important for lasers that need to be moved or deployed in unstable environments. Furthermore, the appropriate clearance makes it easier for maintenance personnel to access various components for inspection, repair, or replacement without disassembling too many parts. It avoids the problem of seeing electronic components 300 but lacking operating space, further simplifying the maintenance process.

[0040] In one embodiment, exemplarily, such as Figure 2 As shown, a heat sink 220 is disposed within the receiving cavity 210 containing the circuit board 310, and the heat sink 220 is attached to the fiber optic assembly 200. The pump source 320 is arranged overlapping the heat sink 220, and the circuit board 310 is at least partially overlapped with the heat sink 220. By allowing the pump source 320 and the circuit board 310 to directly or indirectly contact or partially overlap with the heat sink 220, an efficient heat conduction path can be formed. This helps to quickly transfer the generated heat from the heat-generating element to the heat sink 220 and further dissipate it, thereby effectively reducing the operating temperature of key components such as the pump source 320 and the circuit board 310. The heat sink 220 is attached to the fiber optic assembly 200, using the fiber optic assembly 200 as an additional heat conduction path, increasing the overall heat dissipation area and improving heat dissipation efficiency.

[0041] In one embodiment, for example, the pump source 320 integrates at least two optical pumps and at least one red pump. In other words, this embodiment integrates multiple pump sources 320 together, and also integrates the red pump within the pump source 320. By integrating multiple optical pumps and the red pump, the input energy can be distributed and utilized more efficiently. This allows the embodiment to flexibly adjust the pump sources of different wavelengths or powers according to the specific requirements of the laser medium, ensuring that energy is converted into laser output to the maximum extent. The integrated design also reduces energy transfer losses between different pump sources and avoids energy waste caused by external connections. Furthermore, it can reduce the fiber splicing error rate and improve production efficiency during use.

[0042] On the other hand, integrating multiple pump sources into a single module significantly reduces the system's size and weight, making the entire laser more compact and portable, suitable for space-constrained applications. The integrated design reduces external connection cables and interfaces between pump sources<141, lowering wiring complexity and also reducing potential failure points, thus improving system reliability.

[0043] In one embodiment, exemplarily, such as Figure 3 As shown, the housing 100 has an internal and external connecting mounting port, and a pressure valve 410 is sealed and installed at the mounting port. Many types of lasers require a specific pressure environment to operate to ensure optimal performance. By installing the pressure valve 410, the pressure level inside the housing 100 can be precisely adjusted and maintained by introducing or extracting gas into the housing 100, avoiding pressure fluctuations caused by changes in external pressure or internal heating.

[0044] The pressure valve 410 can automatically adjust when it detects that the air pressure inside the housing 100 exceeds the safe range, such as releasing excess gas in the case of overpressure, or allowing outside air to enter in the case of underpressure, thereby protecting the equipment from damage.

[0045] It should be noted that proper air pressure management helps protect the delicate electronic components 300 and optical components inside the laser from external dust, moisture, or other contaminants. The air pressure valve 410 acts as a barrier to prevent these harmful substances from entering the housing 100.

[0046] It is worth mentioning that, in this embodiment, the pneumatic valve 410 is directly mounted on the housing 100. When it is necessary to regulate the pneumatic pressure, the operator can directly operate the pneumatic valve 410. Compared with the related technologies, where the pneumatic valve 410 requires additional adapter accessories to be mounted on the housing 100, the installation method of this embodiment is simpler and more direct, with higher assembly efficiency and lower production costs.

[0047] In one embodiment, exemplarily, such as Figures 1 to 3 As shown, the outer surface of the housing 100 is provided with a grip portion 130, which is a plastic handle. The plastic handle has an internal cavity filled with a sheet metal support. Choosing plastic as the handle material significantly reduces the overall weight of the device, making it easier for users to carry and operate. By filling the plastic handle with a sheet metal support, the mechanical strength and durability of the handle can be greatly enhanced without significantly increasing its weight. This composite structure effectively resists external forces such as impacts and pulls during daily use, preventing the handle from breaking or deforming.

[0048] In terms of user experience, plastic handles can be designed according to ergonomic principles to provide a better grip and increase comfort.

[0049] Furthermore, considering heat transfer, if the laser generates a large amount of heat during operation, the plastic handle offers better heat insulation than a metal handle, preventing the risk of hand burns due to heat conduction. Even if the internal temperature is high, the external temperature remains within a relatively comfortable range, ensuring normal operation. The internal sheet metal support not only enhances structural strength but also serves as part of an auxiliary heat dissipation path, helping to disperse heat transferred from the interior to the handle and further improving overall thermal management.

[0050] In one embodiment, for example, a seal is provided at the opening 110, and the seals are evenly distributed along the edge of the opening 110 facing the sealing plate 120. When the sealing plate 120 is installed at the opening 110, it compresses the seal to seal the gap between the opening 110 and the sealing plate 120. The seal can effectively prevent dust, moisture and other contaminants from entering the interior of the housing 100, protecting sensitive electronic devices 300 and optical components from contamination and ensuring long-term stable operation of the laser. Furthermore, if the laser needs to maintain a specific gas pressure or gas environment, such as inert gas or other gas filling, good sealing performance can prevent gas leakage and ensure the stability of the internal environment.

[0051] By incorporating sealing elements, the waterproof and dustproof rating of the device can be significantly improved, reaching standards such as IP67 or higher, enabling the laser to operate reliably in harsh environments. Compared to related technologies that use multi-layer foam sealing within the housing, the sealing method in this embodiment not only achieves the same effect but is also easier to assemble and manufacture.

[0052] In one embodiment, for example, a bracket is also provided within the housing 100. The bracket is disposed within the housing 100 and is fitted against the inner wall of the housing 100 to support the housing 100. The bracket is detachably assembled from multiple sheet metal parts. By installing the bracket within the housing 100, the overall rigidity and deformation resistance of the housing 100 can be significantly enhanced, especially when subjected to external impacts, vibrations, or the weight of internal components, effectively preventing deformation or damage to the housing 100. The bracket can evenly distribute the weight and stress of the various components within the housing 100, avoiding structural failure caused by local overload and ensuring long-term stable operation of the equipment.

[0053] The bracket is designed as a detachable assembly of multiple sheet metal parts, allowing each part to be manufactured, transported, and stored independently, reducing manufacturing complexity and costs. The detachable design allows for more flexible assembly methods, facilitating quick installation and commissioning by workers. Furthermore, when repairs or replacements of certain internal components are needed, only the corresponding sheet metal parts need to be disassembled, eliminating the need for large-scale disassembly of the entire unit and minimizing downtime.

[0054] In one embodiment, exemplarily, such as Figure 2 As shown, a control unit 140 is provided on the housing 100. The control unit 140 is electrically connected to the electronic device 300 for operator control of the electronic device 300. The control unit 140 includes a screen and an interface 141 for data communication with the screen. The interface 141 is located at the opening 110 and is covered by a sealing plate 120. The screen provides an intuitive user interface, allowing the operator to easily view system status, parameter settings, and other relevant information. This greatly simplifies the operation process and reduces the possibility of misoperation. Integrating all control functions into a single control unit 140 allows the operator to complete all control tasks in one place without having to distract themselves searching for different control points.

[0055] Interface 141 is located at opening 110 and is shielded by sealing plate 120, effectively preventing dust, moisture, and other contaminants from entering the interior of interface 141 and avoiding functional failure or damage due to poor contact. Sealing plate 120 provides additional physical protection for interface 141, reducing the risk of damage from accidental collisions or external objects and extending the service life of interface 141. Correspondingly, during use, the sealing plate 120 can be directly removed, and any soft adhesive that may be present at interface 141 can be pulled out to perform data processing, data upgrades, and other operations on the control unit 140, further ensuring simplicity and convenience in the use of this embodiment.

[0056] In one embodiment, exemplarily, such as Figure 1As shown, the sealing plate 120 is provided with an armored cable coil cover 121, and a hook 122 for hanging a handheld welding torch is also provided at the edge of the sealing plate 120. The armored cable coil cover 121 can provide physical protection for the optical fiber cable, preventing the optical fiber from being mechanically damaged by bending, squeezing or cutting during use, thereby improving the stability and reliability of the laser system.

[0057] Hooks 122 are installed on the edge of the sealing plate 120 to provide a fixed hanging position for the handheld welding gun, making it easy for the operator to access and store it at any time, reducing the time spent searching for tools and improving work efficiency. By suspending the handheld welding gun on the sealing plate 120, the limited space can also be effectively utilized, making the work area more tidy and orderly, and avoiding the chaos caused by tools being placed randomly.

[0058] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0059] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
