Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0028] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and 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, and therefore should not be construed as a limitation of this application.

[0029] Furthermore, where the term "and / or" appears, it merely describes the relationship between related objects and indicates that three relationships can exist. For example, A and / or B can represent the relationship between A and B: A alone, A and B simultaneously, and B alone. Additionally, the character " / " in this document generally indicates an "or" relationship between the related objects before and after it. Where the terms "first" and "second" appear, these terms are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature specified with "first" or "second" may explicitly or implicitly include at least one of those features. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, four, five, etc., unless otherwise explicitly specified.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0031] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0032] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0033] Please refer to the following: Figures 1 to 4 A laser welding machine 100 provided in one embodiment of this application includes a mounting base 10, a laser assembly 20, a wire feeding assembly 30, and a control assembly 40. The mounting base 10 includes a main body 11 and a cover 12. The main body 11 has an installation space 111 and an opening 112 communicating with the installation space 111. The cover 12 is detachably disposed on the opening 112. The laser assembly 20, the wire feeding assembly 30, and the control assembly 40 are all disposed on the mounting base 10 and are at least partially located within the installation space 111.

[0034] The laser welding machine 100 is specifically a handheld laser welding machine. Understandably, to achieve its normal function, the laser assembly 20 includes a laser 21, a welding torch 23, and a cable 25. The laser 21 generates laser light, and the cable 25 connects the laser 21 and the welding torch 23. The laser beam output from the laser 21 is transmitted to the welding torch 23 via the cable 25. The laser 21 is located in the installation space 111, and the welding torch 23 can be located outside the installation base 10. The installation base 10 is provided with a first placement plate 13 and a second placement plate 14. The first placement plate 13 supports the welding torch 23 when it is not in use, and the second placement plate 14 is used to wrap the cable 25.

[0035] The wire feeding assembly 30 includes a wire feeding reel 31, an air supply drive assembly 33, and a wire feeding sleeve 35. The wire feeding reel 31 is used to wind the welding wire, and the welding wire can be conveyed outward through the wire feeding sleeve 35 under the drive of the air supply drive assembly 33. The wire feeding reel 31 and the air supply drive assembly 33 can be located in the installation space 111 and can be specifically installed on the motor mounting plate 37. The wire feeding sleeve 35 can be located in the main body 11 and connect the inside and outside of the main body 11.

[0036] The control component 40 includes a controller 41 and a command input device. The command input device is communicatively connected to the controller 41, allowing the user to input commands to the controller 41. The controller 41 is communicatively connected to the laser assembly 20 and the wire feeding assembly 30, and is used to control the operation of the laser assembly 20 and the wire feeding assembly 30 according to the user-input commands or the programs stored within it. The controller 41 is located within the mounting space 111, and the command input device is located on the mounting base 10 and is at least partially exposed on the outer surface of the mounting base 10 for user operation.

[0037] In addition, the laser welding machine 100 may also include a power supply assembly 50 and an input terminal 51, an output terminal 53, an air switch 55, etc., connected to the power supply assembly 50. The input and output power supplies for the input terminal 51 and the output terminal 53 may be 220V AC. The laser welding machine 100 may also include a solenoid valve 60, etc., and the mounting base 10 may also have an air inlet 15, a grounding interface 16, etc., which will not be described in detail here.

[0038] The aforementioned laser welding machine 100 integrates the laser component 20, wire feeding component 30, and control component 40 onto the mounting base 10, making it easier to move as a whole and reducing the additional space occupied by separate components, thus providing a better user experience. Furthermore, the cover 12 of the mounting base 10 is detachably installed over the opening 112 of the main body 11. Therefore, even with the integrated design of the laser welding machine 100, users can easily remove the cover 12 to inspect and maintain the components located within the mounting space 111 through the opening 112.

[0039] In some embodiments, the main body 11 includes a frame 113 and a plate, with the plate connecting to the frame 113 and defining an installation space 111. Understandably, the frame 113 is the overall structural component of the main body 11, which can be formed by connecting structures such as square tubing. The plate, as the various surfaces of the main body 11, connects to the frame 113, forming a relatively more enclosed internal space. Furthermore, using square tubing for the frame 113 not only results in an aesthetically pleasing appearance but also a robust structure.

[0040] Specifically, the frame 113 can be generally rectangular, and the plate can include a bottom plate 1141, a front plate 1142, a rear plate 1143, a left side plate 1144, and a right side plate 1145. Correspondingly, the bottom plate 1141 is located at the bottom, the front plate 1142 and the rear plate 1143 are respectively located on the front and rear sides of the frame 113, the left side plate 1144 and the right side plate 1145 are respectively located on the left and right sides of the frame 113, and the opening 112 is formed at the top of the main body 11.

[0041] In some embodiments, the body 11 has a slot 115, and the cover 12 is configured to move along the slot 115 for attachment and removal relative to the opening 112.

[0042] Understandably, slot 115 can be positioned along a first direction parallel to the plane containing opening 112 (e.g., Figure 3 Extending in the X direction (as shown), it can limit the cover 12 located within the slot 115 in a direction intersecting the first direction. During installation, the cover 12 can be inserted into the slot 115 along the first direction and moved to cover the opening 112 with its orientation upward. During removal, the cover 12 can be disengaged from the slot 115 in the opposite direction, so that the opening 112 is fully exposed.

[0043] In this way, the cover 12 can be easily disassembled and assembled, and the slot 115 can limit the cover 12 in directions other than its own extension direction, thereby improving its stability.

[0044] Furthermore, the mounting base 10 also includes a locking element 17, which is detachably mounted on the movement path of the cover 12 along the slot 115.

[0045] Understandably, the locking element 17 is specifically detachably mounted on the movement path of the cover 12 along the slot 115 during disassembly.

[0046] Thus, after the cover 12 is installed in place, a locking element 17 can be installed to block the cover 12 in its movement path, preventing the cover 12 from dislodging from the slot 115 in the disassembly direction. When it is necessary to disassemble the cover 12, the user only needs to remove the locking element 17, and the cover 12 can then be moved outward along the slot 115 and removed normally.

[0047] Specifically, the locking element 17 is an L-shaped plate that is detachably connected to the main body 11 and is at least partially located on the moving path of the cover 12 along the slot 115 for disassembly.

[0048] Furthermore, the main body 11 also includes an adjustment plate 116, which forms a slot 115 with the frame 113 at a distance, and the distance between the adjustment plate 116 and the frame 113 is configured to be adjustable.

[0049] Specifically, the adjustment plate 116 is configured to change its mounting position relative to the frame 113, thereby changing the distance between the two and thus changing the size of the slot 115.

[0050] Thus, the slot 115 formed by the adjusting plate 116 and the frame 113 can change with the change of the distance between the adjusting plate 116 and the frame 113, which can better adapt to the thickness of the cover 12 and thus improve its assembly stability.

[0051] Furthermore, one end of the adjusting plate 116 may have a guide slope, at which the slot 115 gradually widens in an outward direction. In this way, the cover 12 can be inserted into the slot 115 more smoothly under the guidance of the guide slope.

[0052] Specifically, the mounting base 10 includes two adjustment plates 116, which are respectively located on the left side plate 1144 and the right side plate 1145, and form a slot 115 with the top square tube of the frame 113. The cover 12 can be inserted into the slot 115 from back to front.

[0053] The plate body is provided with a waist-shaped hole 1146, and the length direction of the waist-shaped hole 1146 intersects with the top square tube. The two adjusting plates 116 are provided with corresponding connecting holes, and are fixed to the left plate 1144 and the right plate 1145 respectively by connecting parts passing through the connecting holes and the waist-shaped hole 1146.

[0054] Thus, the connector can move along the length of the waist-shaped hole 1146 before it is fully fixed, thereby changing the distance between the adjusting plate 116 and the top square tube.

[0055] In some other embodiments, the adjusting plate 116 and the frame 113 may also be connected by elastic elements or threads in the direction intersecting with the top square tube, thereby changing the distance between the two by the elastic deformation of the elastic elements or the tightness of the threads, etc., without specific limitations.

[0056] In some embodiments, the mounting base 10 further includes at least two handles 18, all of which are located on at least two sides of the main body 11.

[0057] Understandably, the handle 18 may be located on top of the body 11 and at least partially spaced from the body 11 to form a gripping space.

[0058] In this way, users can lift, pull, and push the laser welding machine 100 by using the handle 18, making the laser welding machine 100 more portable and mobile.

[0059] Specifically, the mounting base 10 may include two handles 18, located on the front and rear sides of the main body 11 respectively, so that the user can push and pull the laser welding machine 100 from both the front and rear, and easily apply force to lift the laser welding machine 100 from both the front and rear.

[0060] In some other embodiments, the handles 18 may also be located on the left and right sides; or, the mounting base 10 may include four handles 18, which are located at the front, back, left and right of the main body 11, etc., and no specific limitation is made here.

[0061] In some embodiments, the mounting base 10 further includes a movable wheel 19, which is located at the bottom of the main body 11.

[0062] Understandably, the mounting base 10 can be stably placed on the ground by means of the casters 19. Specifically, the mounting base 10 may include four casters 19, which may be located at the four corners of the bottom. In addition, the casters 19 may be, but are not limited to, omnidirectional wheels.

[0063] In this way, the laser welding machine 100 can be moved more easily with the help of the moving wheels 19, reducing the difficulty for users to push and pull the laser welding machine 100 and making it easier to move.

[0064] In some embodiments, the mounting base 10 has a first side and a second side in the horizontal direction, the welding torch 23 and the cable 25 are disposed on the first side, and the wire feed spool 31 is disposed on the second side.

[0065] Specifically, the first side can be either the left or the right side, and the second side can be either the left or the right side.

[0066] Thus, the welding torch 23 and cable 25 and wire feed spool 31 are located on different sides of the mounting base 10, which can reduce mutual interference between them and each can obtain sufficient installation space 111.

[0067] In some embodiments, the installation space 111 includes a first space in which the laser 21 is disposed, and the first space is configured to accommodate at least two different sizes of laser 21.

[0068] Understandably, the first space being configured to accommodate at least two different specifications of lasers 21 means that the size and shape of the first space are sufficient to accommodate at least two different specifications of lasers 21 for installation. Different specifications of lasers 21 may refer to lasers 21 with different powers, or lasers 21 with different sizes and shapes.

[0069] Different welding processes require different lasers 21 for different materials. The first space can accommodate lasers 21 of different specifications, which helps to improve the compatibility of the laser welding machine 100 and make it more versatile. In the case of different welding materials, simply changing the laser 21 can ensure stable laser output during the welding process and guarantee welding quality.

[0070] In some embodiments, the laser welding machine 100 further includes a wind-cooled heat dissipation assembly (not shown), which is disposed within the installation space 111, and the main body 11 has heat dissipation holes 117 communicating with the installation space 111. Specifically, the wind-cooled heat dissipation assembly can be disposed in the first space to dissipate heat from the laser 21. Heat dissipation holes 117 can be provided on at least the front plate 1142 and the rear plate 1143 of the entire plate.

[0071] Among them, the air-cooled heat dissipation components may include air-cooled fans, heat dissipation fins, etc., as long as they can drive airflow and improve heat exchange efficiency to achieve air-cooled heat dissipation, and no specific limitations are made here.

[0072] In related technologies, laser welding equipment often employs water-cooling systems, which are complex in structure, have a high failure rate, and are heavier. The laser welding machine 100 uses an air-cooling system formed by air-cooling components, which has a simpler structure, helping to reduce equipment costs. The air-cooling effect improves its high-efficiency continuous welding capability, increasing production efficiency and reducing labor costs. At the same time, the air-cooling components are lighter, contributing to the portability of the laser welding machine 100.

[0073] In addition, the main body 11 has heat dissipation holes 117, which, together with the operation of the air-cooled heat dissipation components, can force air cooling of the laser 21 and quickly remove the heat generated during the welding process, thereby ensuring the stable operation of the equipment.

[0074] In some embodiments, the laser assembly 20 further includes a corrugated tube and a protective sleeve 27. The corrugated tube is sleeved outside the cable 25, and the protective sleeve 27 is sleeved on the corrugated tube near the plate and connected to the plate.

[0075] In this way, the corrugated pipe can protect the cable 25, and the protective sleeve 27 can protect the corrugated pipe, reducing the probability of fatigue fracture due to repeated bending of the corrugated pipe.

[0076] In some embodiments, the instruction input device includes a touch screen 43 and a wire feeding control panel 45, both of which are disposed on the mounting base 10 and are at least partially exposed on the outer surface of the mounting base 10.

[0077] Understandably, the touchscreen 43 can form virtual buttons and display commands and guidance. Furthermore, the wire feeding assembly 30 can be controlled by commands input through the touchscreen 43 or by commands input through the wire feeding control panel 45.

[0078] For non-professional users, the complexity of operating laser welding equipment is a common obstacle. Simplifying the user interface and processes, and providing intuitive operating guidance, is key to improving user experience and increasing equipment adoption. The touchscreen 43 offers better information interaction capabilities, making it easier for users to operate and allowing even non-professionals to quickly get started, thus contributing to improved user experience and equipment adoption. Furthermore, for quick operation of the wire feeding assembly 30, it can also be done directly through the wire feeding control panel 45.

[0079] Specifically, the main body 11 is equipped with a touch screen 43 which can be tilted to facilitate user operation.

[0080] In some embodiments, the control component 40 further includes control buttons, including a power-on switch 471, a wire feeding power-on switch 473, and an emergency stop switch 475, to enable one-button operation of the corresponding functions and improve the ease of operation of the laser welding machine 100.

[0081] In some embodiments, the control component 40 further includes an indicator light 49, which is capable of emitting at least two display signals.

[0082] Understandably, different display signals correspond to different working states of laser 21. Different display signals can be differences in the number of indicator lights 49 that are lit, differences in the color displayed by a single indicator light 49, or differences in the duration of a single indicator light 49 that is lit, etc., as long as they can be observed and distinguished.

[0083] In one embodiment, the control component 40 further includes three indicator lights 49, and the illumination of the three indicator lights 49 corresponds to the laser 21 being powered on, powered on, and malfunctioning, respectively.

[0084] In this way, the user can know the current working status of the laser 21 based on the display signal of the indicator light 49.

[0085] In addition, the touch screen 43 can also display the operating parameters of at least one of the laser assembly 20, wire feeding assembly 30, control assembly 40 and power supply assembly 50, so that the user can keep track of the operating status of the laser welding machine 100.

[0086] The aforementioned laser welding machine 100 integrates the laser component 20, wire feeding component 30, and control component 40 onto the mounting base 10. It employs air cooling with heat dissipation holes 117, resulting in a higher degree of integration and lighter weight, facilitating movement and portability. This allows for wide adaptability to various applications, and the excellent heat dissipation also contributes to improved welding stability. Furthermore, the laser welding machine 100 features a compatible structure; the first space within the main body 11 can accommodate lasers 21 of various powers. Selecting the appropriate power allows for excellent welding quality on various materials of different thicknesses. Users can also inspect and maintain the internal components of the laser welding machine 100 by disassembling the cover 12, operate the machine via command input and control buttons, and obtain the current operating status of the laser 21 via indicator lights 49.

[0087] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0088] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
