Description

Technical Field

[0001] The utility model belongs to the technical field of laser welding equipment design, and specifically relates to an integrated laser welding machine and a handheld laser welding equipment. Background Art

[0002] The handheld laser welding equipment is equipped with a handheld welding gun. Due to the advantages of the handheld welding gun, such as flexible control, fast welding speed and beautiful welds, the handheld laser welding equipment is very popular among users.

[0003] In the specific welding process, as the welding position changes, the user will hold the handheld welding gun and move it, and use the power cord, welding wire tube, gas pipe, laser transmission fiber, control signal line, etc. to pull the battery pack, welding wire storage module, gas cylinder, optical module, control box module and other equipment to move, so as to adapt to the new welding position. Because these devices are independent of each other and large in size, the wires and various chassis are placed in a messy manner in the processing site, which seriously affects the overall portability and flexibility of the handheld welding equipment. Utility Model Content

[0004] The utility model discloses an integrated laser welding machine and a handheld laser welding device, so as to solve the problem of low portability and flexibility of the handheld welding device as a whole in the prior art.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] In a first aspect, an embodiment of the utility model discloses a laser welding machine, comprising a chassis and a gas cylinder, an optical module, a battery pack, a welding wire storage module and a heat dissipation structure compactly arranged inside the chassis along the direction of gravity.

[0007] In the second aspect, an embodiment of the utility model discloses a handheld laser welding device, which includes an integrated armored cable, a handheld welding gun and a laser welding machine described in any one of claims 1 to 4, wherein the two ends of the integrated armored cable are respectively provided with a first connector and a second connector, one end of the integrated armored cable is fixed to a side wall of the chassis close to the gas outlet of the gas cylinder through the first connector, and the other end of the integrated armored cable is fixed to the tail end of the handheld welding gun through the second connector, and the first connector and the chassis as well as the second connector and the handheld welding gun are respectively connected by one or more of threads, adapter blocks, fasteners and clip-on connections.

[0008] The technical solution adopted by the utility model can achieve the following technical effects:

[0009] 1. Integrate the gas cylinder, optical module, battery pack, and welding wire storage module into the chassis to achieve their integration. This structure enables the user to directly pull an overall modular laser welding machine when changing the welding position, which is more flexible in use. This solution effectively solves the problem of low portability and flexibility of handheld welding equipment in the prior art.

[0010] 2. At the same time, the laser welding machine disclosed in the embodiment of the utility model is not a simple piece together of gas cylinders, optical modules, battery packs, and welding wire storage modules. The laser welding machine disclosed in the embodiment of the utility model makes full use of the gas cylinder, a component with a relatively low temperature, to conduct heat to the battery pack and the optical module, thereby dissipating heat and cooling the battery pack and the optical module. At the same time, a passive heat dissipation method of a heat sink group is combined with an active heat dissipation method of a fan to achieve efficient and rapid heat dissipation of the heat generated by heat-generating devices such as battery packs and optical modules during operation. It can be seen that the laser welding machine disclosed in the embodiment of the utility model forms a multiple cooling structure through targeted design of the structure, and can ultimately achieve better heat dissipation and cooling of the heat-generating devices integrated in the chassis, avoiding the problem that the heat generated by the heat-generating devices cannot be dissipated due to the integrated design, resulting in the difficulty of stable integration.

[0011] 3. At the same time, the gas cylinder not only serves as a gas source, but also helps cool the battery pack and optical module, thereby achieving a one-piece multi-purpose effect. In this case, the laser welding machine does not need to be equipped with too many cooling and heat dissipation devices, which is conducive to the miniaturization design of the laser welding machine. This structure of the laser welding machine is also more convenient for users to drag and move when changing the welding position. In addition, due to the large size and weight of the gas cylinder, setting the gas cylinder at the bottom of the chassis can also make the gas cylinder play a counterweight role, so that the entire laser welding machine can be more stable during the pulling and moving process, and not easy to tip over.

[0031] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0032] The technical solutions disclosed in various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] Please refer to Figures 1 to 7 The embodiment of the utility model discloses a laser welding machine, which is a part of a handheld laser welding device. The laser welding machine disclosed in the embodiment of the utility model comprises a chassis 10, a gas cylinder 20, an optical module 30, a battery pack 40, a welding wire storage module 50 and a heat dissipation structure 60.

[0034] The chassis 10 is a basic component of the laser welding machine, which can not only provide an installation basis for other components of the laser welding machine, but also provide protection for the components arranged in the chassis 10. In the embodiment of the utility model, the gas cylinder 20, the optical module 30, the battery pack 40, the welding wire storage module 50 and the heat dissipation structure 60 are all installed in the chassis 10 with the chassis 10 as the installation basis, thereby forming an integrated module with the chassis 10 as the shell.

[0035] In order to improve the protection capability and provide good support capability, the chassis 10 can be made of a metal material with high strength, such as stainless steel. Of course, the chassis 10 can also be made of a non-metal material with high strength, such as polyethylene. The embodiment of the utility model does not limit the specific material of the chassis 10.

[0036] The gas cylinder 20 is used to contain the shielding gas. The shielding gas can be an inert gas, or other gas that can form a shielding atmosphere that is isolated from air at the welding position during the welding process. The embodiment of the utility model does not limit the specific type of shielding gas. During welding, the shielding gas forms a shielding atmosphere that is isolated from air at the welding position, thereby preventing the air from oxidizing the welding position at high temperature and causing the problem of poor welding quality. Since a large amount of shielding gas is required during the welding process, the volume of the gas cylinder 20 is large, and a large amount of compressed (for example, liquid) shielding gas is stored in the gas cylinder 20. The weight of the gas cylinder 20 is large, and the gas cylinder 20 is not a heat source, so the overall temperature of the gas cylinder 20 is relatively low. In the embodiment of the utility model, the gas cylinder 20 is arranged at the bottom of the chassis 10, that is, the gas cylinder 20 is at a lower position on the chassis 10.

[0037] The battery pack 40 is the energy module of the handheld welding device. The battery pack 40 can provide electrical energy for the electrical components of the handheld welding device and is a heat generating device in the laser welding machine. Specifically, the battery pack 40 is electrically connected to the electrical components of the handheld welding device, thereby providing power to these electrical components. For example, the optical module 30 needs electricity in the process of generating laser, and the battery pack 40 is electrically connected to the optical module 30, thereby providing power to the optical module 30.

[0038] The optical module 30 is a device for generating laser. The laser generated by the optical module 30 will eventually be transmitted to the welding position, thereby providing the high temperature required for welding. The optical module 30 will also generate a large amount of heat during operation, so the optical module 30 is also a heat-generating device in the laser welding machine. In an embodiment of the utility model, the battery pack 40 and the optical module 30 are respectively arranged on opposite sides of the gas cylinder 20, and respectively cooperate with the gas cylinder 20 for heat conduction to cool down through the gas cylinder 20. Specifically, the battery pack 40 and the optical module 30 are respectively located on opposite sides of the gas cylinder 20 in the horizontal direction.

[0039] Specifically, the battery pack 40 and the gas cylinder 20 as well as the optical module 30 and the gas cylinder 20 can achieve direct thermal coordination through direct contact, or can achieve indirect thermal coordination by setting a thermally conductive material with a high thermal conductivity between them, which is not limited in the embodiments of the present utility model.

[0040] The welding wire storage module 50 is used to store the welding wire 93. In the specific welding process, the welding wire 93 will be consumed, so as the welding work continues, the welding wire 93 will continue to be drawn out from the welding wire storage module 50. The structure of the welding wire storage module 50 can be various. For example, the welding wire storage module 50 can be a welding wire storage box. For another example, the welding wire storage module 50 can be a welding wire reel, which can be rotatably arranged in the chassis 10. As the welding work continues, the welding wire reel continues to rotate to realize the release of the welding wire 93. In the embodiment of the utility model, the welding wire storage module 50 is arranged above the gas cylinder 20.

[0041] The heat dissipation structure 60 is the heat dissipation part of the laser welding machine, which is used to conduct heat generated by the heat generating device of the laser welding machine during operation. In the embodiment of the utility model, the heat dissipation structure 60 includes a heat sink group 61 and a fan 62. The fan 62 is supported above the heat sink group 61 and is located between the top cover 11 of the chassis 10 and the heat sink group 61. The heat sink group 61 is located between the fan 62 and the gas cylinder 20.

[0042] The chassis 10 has a top cover 11 and a bottom cover that are arranged opposite to each other. The top cover 11 and the bottom cover are respectively provided with first heat dissipation holes 111 to form a convection space. The fan 62, the heat sink group 61 and the gas cylinder 20 are sequentially arranged in the convection space from top to bottom. Specifically, there are a plurality of first heat dissipation holes 111, and they are arranged in an array. The heat sink group 61 includes a plurality of heat sinks 611 arranged in a row, and a first air gap 612 is provided between two adjacent heat sinks 611. The fan 62 is used to drive air flow, and the first air gap 612 is connected to the air inlet end of the fan 62, and the air outlet end of the fan 62 is connected to the first heat dissipation hole 111.

[0043] The plurality of heat sinks 611 may be made of a material with good thermal conductivity, for example, the material of the plurality of heat sinks 611 may be a metal material (such as stainless steel, copper, etc.). The first air gap 612 facilitates air flow, thereby facilitating rapid removal of heat energy introduced to the heat sink 611 by air convection.

[0044] In the specific heat dissipation process, the heat generated by the heat-generating device in the laser welding machine during operation will be transmitted to the heat sink group 61. Driven by the fan 62, the air flows faster and passes through the first air gap 612, the fan 62 and the first heat dissipation hole 111 in sequence and flows out of the laser welding machine, thereby finally bringing the heat out of the laser welding machine and dissipating it.

[0045] The laser welding machine disclosed in the embodiment of the utility model integrates the gas cylinder 20, the optical module 30, the battery pack 40, and the welding wire storage module 50 in the chassis 10, so as to realize their integration. This structure enables the user to directly pull an integral modular laser welding machine when changing the welding position. Compared with pulling the gas cylinder 20, the optical module 30, the battery pack 40, and the welding wire storage module 50 separately to move them, which may easily cause damage to each other and to equipment in the environment, the gas cylinder 20, the optical module 30, the battery pack 40 and the welding wire storage module 50 are integrated in the chassis 10, so that there will be no collision between these components during the movement, and the probability of collision with equipment in the environment can also be reduced.

[0046] At the same time, the laser welding machine disclosed in the embodiment of the utility model is not a simple piece together of the gas cylinder 20, the optical module 30, the battery pack 40, and the welding wire storage module 50. The laser welding machine disclosed in the embodiment of the utility model makes full use of the gas cylinder 20, which is a component with a relatively low temperature, to conduct heat to the battery pack 40 and the optical module 30, thereby dissipating heat and cooling the battery pack 40 and the optical module 30. At the same time, the heat sink group 61, a passive heat dissipation method, is combined with the fan 62, an active heat dissipation method, to achieve efficient and rapid heat dissipation of the heat generated by the heat-generating devices such as the battery pack 40 and the optical module 30 during operation. It can be seen that the laser welding machine disclosed in the embodiment of the utility model forms a multiple heat dissipation and cooling structure through targeted design of the structure, and can ultimately achieve better heat dissipation and cooling of the heat-generating devices integrated in the chassis, avoiding the problem that the heat generated by the heat-generating devices cannot be dissipated due to the integrated design, which makes it difficult to stably achieve integration.

[0047] At the same time, the gas cylinder 20 not only serves as a gas source, but also can assist in cooling the battery pack 40 and the optical module 30, thereby achieving a one-thing-for-multiple-purposes effect. In this case, the laser welding machine does not need to be equipped with too many cooling and heat dissipation devices, which is conducive to the miniaturized design of the laser welding machine. The laser welding machine with this structure is also more convenient for users to drag and move when users change the welding position. In addition, due to the large volume and weight of the gas cylinder 20, setting the gas cylinder 20 at the bottom of the chassis 10 can also make the gas cylinder 20 play a counterweight role, so that the entire laser welding machine can be more stable during the pulling and moving process, and not easy to tip over. This can further reduce the probability of collision during movement.

[0048] In order to facilitate the control during the welding process, the laser welding machine disclosed in the embodiment of the utility model may also include a control box module 70, which is used to control some components of the handheld laser welding device. For example, the control box module 70 can control the battery pack 40, the optical module 30, and the handheld welding gun 92 mentioned later. The control box module 70 is arranged in the chassis 10. In the embodiment of the utility model, the control box module 70 can be arranged in multiple positions in the chassis 10, and the embodiment of the utility model is not limited.

[0049] Since the heat dissipation structure 60 includes a heat sink group 61 and a fan 62, and in order to dissipate heat better, the heat sink group 61 and the fan 62 are designed to have larger dimensions in the stacking direction of the heat sink group 61 and the fan 62, while the welding wire storage module 50 and the heat dissipation structure 60 are arranged side by side above the gas cylinder 20, and the size of the welding wire storage module 50 in the stacking direction of the heat sink group 61 and the fan 62 can be designed to be smaller. Based on this, in one embodiment, the control box module 70 can be arranged between the welding wire storage module 50 and the gas cylinder 20. The welding wire storage module 50 is supported on the control box module 70. In this case, the welding wire storage module 50 and the control box module 70 are stacked above the gas cylinder 20, thereby making full use of the space arranged side by side with the heat dissipation structure 60, which is conducive to a more compact structure of the laser welding machine.

[0050] Furthermore, the gas cylinder 20 and the welding wire storage module 50 can be respectively thermally coordinated with the control box module 70 to cool the control box module 70. The control box module 70 also generates heat during operation. This embodiment uses the gas cylinder 20 to cool the control box module 70 to avoid excessive temperature of the control box module 70. This can make the layout of the laser welding machine more reasonable. At the same time, the control box module 70 also cooperates with the welding wire storage module 50 for thermal conductivity, so that the heat generated by the control box module 70 can be transferred to the welding wire storage module 50, thereby preheating the welding wire 93, so that the welding wire stored in the welding wire storage module 50 will not be too low in temperature to affect the flexibility of the welding wire, and the welding wire storage module 50 is easier to release the wire. This embodiment can not only make full use of the gas cylinder 20 to cool down, but also make full use of the heat generated by the control box module 70 during operation to preheat the welding wire 93, which makes the layout of the control box module 70 more reasonable.

[0051] Similarly, the control box module 70 can achieve thermal coordination with the gas cylinder 20 or the welding wire storage module 50 through direct contact or through a heat-conducting member with a high thermal conductivity, and the embodiment of the utility model does not limit the thermal coordination method between them. In other embodiments, the control box module 70 may not be thermally coordinated with the gas cylinder 20 or the welding wire storage module 50.

[0052] In the specific welding process, the shielding gas is gradually consumed. Once the shielding gas is consumed, the gas cylinder 20 needs to be replaced. Based on this, in one embodiment, the gas cylinder 20 can be detachably installed in the chassis 10. There are many ways to achieve the detachable installation of the gas cylinder 20. In a more specific embodiment, the battery pack 40, the control box module 70, the heat dissipation structure 60 and the optical module 30 surround the installation space. The chassis 10 may be provided with an avoidance hole 121, and the gas cylinder 20 can be inserted into the installation space through the avoidance hole 121. In this case, the user can realize the disassembly and assembly of the gas cylinder 20 by pushing and pulling operations during the process of replacing the gas cylinder 20, thereby facilitating the replacement of the gas cylinder 20. In order to facilitate the user's pulling and pulling operations, a gripping handle may be provided at the end of the gas cylinder 20 adjacent to the avoidance hole 121. During the specific operation process, the user can manipulate the gripping handle to realize the push-pull operation of the gas cylinder 20.

[0053] Of course, in order to prevent the end of the gas cylinder 20 from being exposed through the avoidance hole 121, the avoidance hole 121 can be installed with a shielding structure, and the shielding structure can be detachably connected to the chassis 10, so as to achieve the coverage of the avoidance hole 121. When removing the gas cylinder 20, the user can remove the shielding structure. The shielding structure can be a concealing panel, or other structure that can cover the avoidance hole 121. The embodiment of the utility model does not limit the specific structure of the shielding structure.

[0054] In order to improve the installation stability of the gas cylinder 20, locking devices can be respectively provided at the two ends of the chassis 10 adjacent to the gas cylinder 20. The locking devices can respectively lock the two ends of the gas cylinder 20, thereby preventing the gas cylinder 20 from moving, and ultimately enabling the gas cylinder 20 to be more stably installed in the chassis 10.

[0055] In order to dissipate heat better, in one embodiment, a second air gap 14 may be provided between the gas cylinder 20 and the components enclosing the installation space, and the second air gap 14 is connected to the avoidance hole 121, and is connected to the external environment of the laser welding machine through the avoidance hole 121. The extension direction of the second air gap 14 is different from the extension direction of the first air gap 612. Specifically, the extension direction of the first air gap 612 may be perpendicular to the extension direction of the second air gap 14. In this case, the heat inside the chassis 10 can be output to the outside of the chassis 19 through the first air gap 612 and the second air gap 14, respectively, so as to achieve multi-directional heat dissipation, which can greatly improve the heat dissipation capacity of the laser welding machine.

[0056] Furthermore, the shielding structure mentioned above can be a fan structure, which is installed at the avoidance hole 121 to achieve hiding. At the same time, the fan structure can drive air flow, so that the air in the chassis 10 carries heat and is output to the outside of the chassis 10 more efficiently, and finally achieves better heat dissipation.

[0057] In the embodiment of the utility model, the heat sink group 61 and the optical module 30 can be in direct contact to achieve thermal coordination, or can be indirectly thermally coordinated through other middleware, as long as the heat generated by the optical module 30 during operation can be transferred to the heat sink group 61. In one embodiment, the chassis 10 may include a first side cover 13, the top end of the first side cover 13 may be connected to the top cover 11, the first side cover 13 is located on the first side of the heat sink group 61 and the optical module 30, and the heat sink group 61 is connected to the first side cover 13 and thermally coordinated. The optical module 30 is in thermal contact with the heat sink group 61 and the first side cover 13 respectively. In this case, the optical module 30 can achieve thermal coordination with the heat sink group 61 through the first side cover 13. In this case, the first side cover 13 is connected to the optical module 30 and the heat sink group 61, so as to at least assist the installation of the optical module 30 and the heat sink group 61, so that the optical module 30 and the heat sink group 61 are more stable in the chassis 10, and the first side cover 13 also plays a thermal conductive function.

[0058] The chassis 10 disclosed in the embodiment of the utility model may further include a second side cover 12 . The second side cover 12 and the first side cover 13 may be two adjacent side covers. The second side cover 12 may be provided with the avoidance hole 121 mentioned above.

[0059] In addition, as a part of the chassis 10, the first side cover 13 can cooperate with other components of the chassis 10 (such as the top cover 11, the second side cover 12 and the third side cover mentioned later, etc.), so as to facilitate the heat generated by the optical module 30 when working to be conducted to the entire chassis 10, and the heat is dissipated into the environment with the outer surface of the entire chassis 10 as the heat dissipation surface, which is more conducive to the all-round heat dissipation and cooling of the laser welding machine.

[0060] The chassis 10 disclosed in the embodiment of the utility model may include a top cover 11, a bottom cover and a plurality of side covers, wherein the plurality of side covers may include a first side cover 13, a second side cover 12 and a third side cover mentioned later. In the embodiment of the utility model, the top cover 11, the bottom cover and the side cover are detachable structural parts that can be removed from a laser welding machine. This structure enables them to be disassembled, thereby facilitating the exposure of the internal structure of the corresponding part of the chassis 10, and further facilitating maintenance or replacement of parts.

[0061] Furthermore, the top cover 11 may be provided with a handle, which can be grasped by the user, so that the user can lift the entire laser welding machine to achieve displacement when necessary. In the embodiment of the utility model, the top cover 11 can be matched with other parts of the chassis 10 by a detachable connection or a rotating connection, so that the user can open the top cover 11 when it is necessary. Furthermore, the top cover 11 can be locked and fastened with other parts of the chassis 10 (such as the side cover) by the top cover lock 15.

[0062] In order to further improve the heat dissipation performance, in a further optional solution, the bottom cover and the side cover may also be provided with a second heat dissipation hole, so that the entire laser welding machine has a better heat dissipation performance. Furthermore, the second heat dissipation hole is provided in the area opposite to the heating device on the bottom cover or the side cover, so that more targeted heat dissipation can be achieved.

[0063] In a further technical solution, the laser welding machine disclosed in the embodiment of the utility model may also include a metal connecting plate 81, which may be arranged on the second side of the heat sink group 61. It should be noted that the second side of the heat sink group 61 and the first side of the heat sink group 61 are the opposite sides of the heat sink group 61. The top of the metal connecting plate 81 may be connected to the heat sink group 61. The bottom end of the metal connecting plate 81 may be connected to the battery pack 40, and the metal connecting plate 81 is at least used to transfer the heat generated by the battery pack 40 to the heat sink group 61. Specifically, the heat sink group 61 may be supported on the battery pack 40 by the metal connecting plate 81. In this case, the heat sink group 61 can be supported on the battery pack 40 by the metal connecting plate 81, so that the heat sink group 61 can be installed more stably. At the same time, the metal connecting plate 81 can also play a heat conduction function, so that the heat generated by the battery pack 40 during operation is transferred to the heat sink group 61, so as to achieve better heat conduction, which can further facilitate the final dissipation of heat.

[0064] At the same time, the heat sink group 61 is connected to the first side cover 13 and the metal connecting plate 81 on its opposite first and second sides, respectively, so that the heat sink group 61 can be installed more evenly and stably, and at the same time, the heat generated by the battery pack 40 and the optical module 30 can be more evenly dissipated, which is conducive to more balanced heat dissipation.

[0065] The chassis 10 disclosed in the embodiment of the utility model may further include a third side cover, and the third side cover may be opposite to the first side cover 13. The metal connecting plate 81 may be a bent structure, and the metal connecting plate 81 is bent to form a recessed structure 141 facing the third side cover. In this case, the metal connecting plate 81 with a bent structure has a higher strength, so that it can better support the heat sink group 61. At the same time, the recessed structure 141 is formed by bending the metal connecting plate 81 to create a space, which is conducive to the layout of other components of the laser welding machine in the recessed structure 141. In the embodiment of the utility model, the metal connecting plate 81 can be made of a material with high strength and good thermal conductivity. For example, the metal connecting plate 81 can be a stainless steel bent plate, a copper plate, etc. The embodiment of the utility model does not limit the specific material of the metal connecting plate 81.

[0066] The laser welding machine disclosed in the embodiment of the utility model may also include a welding wire driving module 82, which cooperates with the welding wire storage module 50, and the welding wire driving module 82 is used to drive the welding wire 93 stored in the welding wire storage module 50 to collect and release the wire. Under the drive of the welding wire driving module 82, the welding wire 93 moves to finally realize the transportation of the welding wire 93. In a more specific embodiment, the welding wire driving module 82 can be arranged in the recessed structure 141. In this case, the welding wire driving module 82 makes full use of the recessed structure 141 formed after the metal connecting plate 81 is bent for layout, which is conducive to improving the compactness of the structure of the laser welding machine.

[0067] Further, a heat-conducting support member 142 may be provided in the recessed structure 141, and the heat-conducting support member 142 may be a heat-conducting support plate, or other structures that can play a supporting role. The heat-conducting support member 142 may be provided with a wire guide tube 143, and the wire guide tube 143 is located between the welding wire driving module 82 and the welding wire storage module 50. In a specific welding process, the welding wire 93 released from the welding wire storage module 50 may pass through the wire guide tube 143 and the welding wire driving module 82 in sequence. The direction of the wire guide tube 143 may be adjusted so that the welding wire 93 moves in a preferred path. The wire guide tube 143 is also used to preheat the passing welding wire 93. In the specific welding process, the heat generated by the battery pack 40 will be conducted along the metal connecting plate 81 to the heat sink group 61, and the heat-conducting support member 142 is arranged in the recessed structure 141, so part of the heat transmitted on the metal connecting plate 81 will be conducted along the heat-conducting support member 142 to the wire guide tube 143, and finally transmitted to the traveling welding wire 93 through the wire guide tube 143, so that the welding wire 93 can be preheated. This structure can preheat the welding wire 93, so that the temperature of the welding wire 93 finally transmitted to the welding position is not too low, which is conducive to the welding wire 93 to participate in welding more efficiently.

[0068] At the same time, the metal connecting plate 81 forms a recessed structure 141, which can provide accommodation space for the welding wire drive module 82, the heat-conducting support member 142 and the wire guide tube 143, while also being able to preheat the welding wire 93. Ultimately, a structure that combines the advantages of compact layout, preheating the welding wire 93 and assisting heat conduction can be formed, thereby improving the various performance aspects of the laser welding machine disclosed in the embodiment of the utility model.

[0069] In order to further improve the heat dissipation performance of the laser welding machine, the laser welding machine disclosed in the embodiment of the utility model may also include a heat pipe 83. The heat pipe 83 can achieve directional heat conduction, so as to be more conducive to the targeted directional conduction of the heat generated by the heat generating device when it is working. The heat pipe 83 can be one or more, and the embodiment of the utility model does not limit the specific number of the heat pipes 83.

[0070] Since the light module 30 generates a large amount of heat during operation, based on this, the evaporation end 831 of the heat pipe 83 can be thermally connected to the light module 30, and the condensation end 832 of the heat pipe 83 can be thermally connected to the heat sink group 61. In this case, the evaporation end 831 of the heat pipe 83 absorbs the heat generated by the light module 30, so that the heat-conducting medium (such as water) in the heat pipe 83 is vaporized and transferred to the condensation end 832 of the heat pipe 83, and finally condenses at the condensation end 832 of the heat pipe 83 to release heat. The condensed heat-conducting medium will flow back to the evaporation end 831 of the heat pipe 83 under the guidance of the capillary structure in the heat pipe 83, and then participate in the next heat conduction cycle. In this process, the heat generated by the light module 30 during operation will be transmitted to the heat sink group 61 along the extension direction of the heat pipe 83, thereby achieving more direct and directional heat conduction, which is ultimately conducive to improving the heat conduction efficiency. This method of combining liquid heat conduction with wind heat conduction formed by the cooperation of the heat sink group 61 and the fan 62 mentioned above can improve the heat dissipation performance of the laser welding machine.

[0071] Furthermore, the evaporation end 831 of the heat pipe 83 can be lower than the condensation end 832 of the heat pipe 83. In this case, after the heat transfer medium is condensed into a liquid at the condensation end 832 of the heat pipe 83, it can flow to the evaporation end 831 of the heat pipe 83 more easily and quickly under the action of gravity, thereby entering the next heat transfer cycle faster. This structure makes the heat pipe 83 easier to operate, which is more conducive to the heat pipe 83 to implement more efficient heat conduction. Of course, the heat pipe 83 can also be connected between the battery pack 40 and the heat sink group 61. Considering that the heat module 30 generates more heat than the battery pack 40 during operation, the heat pipe 83 is designed to connect the light module 30 and the heat sink group 61. The structure is more targeted.

[0072] Optionally, the heat pipe 83 is in a 7-shaped structure as a whole, the condensation end 832 of the heat pipe 83 is attached to the upper surface of the heat sink group 61, and the evaporation end 831 of the heat pipe 83 is attached to the outer wall of the battery pack 40, thereby saving space and forming a compact layout. Optionally, the condensation end 832 of the heat pipe 83 is arranged in the vertical direction, and under the action of gravity, the water reflux inside the heat pipe 83 is accelerated, so that the maximum heat removal power is more than 50% higher than that of a flat gravity heat pipe.

[0073] As described above, in the specific working process, the condensation end 832 of the heat pipe 83 condenses and releases heat. Based on this, in a further optional solution, there may be a wire gap between the condensation ends 832 of the multiple heat pipes 83. Specifically, the wire gap may be a part of the first air gap 612. The wire gap is located on the transmission path of the welding wire 93. The welding wire 93 released by the welding wire storage module 50 can pass through the wire gap and thermally contact with the condensation end 832 of at least part of the heat pipe 83. In this case, since the welding wire 93 will be in thermal contact with the condensation end 832 of the heat pipe 83 during the transmission process, the welding wire 93 can be preheated, so that the welding wire 93 has a certain temperature when it is transported to the welding position, which is more conducive to the welding wire 93 to participate in welding better, thereby improving the welding efficiency and welding quality. Of course, since the welding wire 93 can be preheated, the welding wire 93 is more flexible during the transmission process, which is conducive to improving the adaptability of the welding wire 93 during the transmission process.

[0074] Furthermore, the laser welding machine also includes a frame arranged inside the chassis and connected to the chassis, and the heat dissipation structure 60, the welding wire storage module 50, the battery pack 40, the optical module 30 and the gas cylinder 20 can be detached from the frame. Secondly, the heat conductive support 142 and the metal connecting plate 81 are connected to the frame, which can effectively enhance the strength and stability of the entire chassis. The frame can be a support frame of the frame, or a structure such as multiple support columns.

[0075] Furthermore, the chassis 10 also includes wire tubes, which include air pipes, optical fibers and wires. A plurality of wire tube fixing positions are provided on the inner wall and / or the frame of the chassis. The wire tube fixing positions can be configured as: slots, buckles or cable ties, etc., to fix the wire tubes, facilitate wiring, and further save space.

[0076] Optionally, there may be a plurality of gas cylinders 20 , and each gas cylinder 20 is vertically placed side by side at the bottom of the chassis 10 .

[0077] Optionally, the gas cylinder 20 may also be arranged in a lying position at the bottom of the chassis 10. In order to improve its safety, a plurality of fixing brackets, fixing slots and corresponding shock absorbing components are arranged in the chassis 10 to fix the gas cylinder 20 to prevent the gas cylinder 20 from shaking and causing an explosion. In addition, a corresponding pressure relief valve is arranged at the outlet of the gas cylinder 20.

[0078] On the other hand, in order to ensure the refrigeration effect of the gas cylinder 20, air flow needs to be ensured between the various fixed positions.

[0079] In addition, a temperature alarm device is provided inside the laser welding machine to monitor the surface temperature of the optical module 30, the battery pack 40, the control box module 70, and the ambient temperature inside the chassis 10 to prevent damage to electrical components and unsafe accidents of gas cylinders caused by excessively high or low temperatures.

[0080] Optionally, there is a certain gap between each device inside the chassis 10 and the gas cylinder 20, or a buffering component with good thermal conductivity is set, which on the one hand increases the air circulation between the device and the gas cylinder 20; on the other hand reduces the friction and shaking between the device and the gas cylinder 20, so as to improve the stability and safety of the gas cylinder.

The battery pack 40 is electrically connected to the handheld welding gun 92 through the power cord 912, and is also used to power the electrical components in the handheld welding gun 92. The welding wire tube 913 is used for the welding wire 93 traveling during the transmission process to pass through, and guide the welding wire 93 to be transported toward the handheld welding gun 92, and finally transported from the handheld welding gun 92 to the welding position. One end of the gas pipe 914 is connected to the gas cylinder 20, and the other end of the gas pipe 914 is connected to the handheld welding gun 92, and is sprayed from the handheld welding gun 92 to the welding position during welding. One end of the laser transmission optical fiber 915 is connected to the optical module 30, and the other end of the laser transmission optical fiber 915 is connected to the handheld welding gun 92.

[0085] This structure integrates some pipelines into the protective cover 911 to form a modular armored cable 91, so that when the user pulls the laser welding machine to move, the pipelines will not be entangled or interfered with each other, nor will they be entangled or connected with equipment in the environment, thereby facilitating the user's pulling operation.

[0086] In the case where the laser welding machine includes a control box module 70 disposed in the chassis 10, the armor cable 91 may further include a control signal line 916, and the control signal line 916 may also be integrated in the protective cover 911. One end of the control signal line 916 is electrically connected to the control box module 70, and the other end passes through the protective cover 911 and is electrically connected to the handheld welding gun 92, thereby controlling the handheld welding gun 92.

[0087] As the outermost layer, the protective cover 911 can be made of wear-resistant insulating material to alleviate the wear between the protective cover 911 and the ground during the dragging process. For example, the protective cover 911 can be made of polyethylene material. Of course, it can also be made of other materials.

[0088] Furthermore, the first connector 94 and the chassis 10 as well as the second connector and the handheld welding gun 92 are respectively connected in one or more ways including threads, adapter blocks, fasteners and clamping.

The transfer block 95 is hollow, and pipelines and other devices pass through the transfer block 95 and lead to the interior of the first connector 94 .

[0090] In order to prevent the pipelines from being worn in the protective cover 911 during the pulling process, in a further embodiment, the armored cable 91 disclosed in the embodiment of the utility model may further include a filler 917, which is filled in the protective cover 911 and fills the gaps between the pipelines in the protective cover 911, thereby separating the pipelines and preventing the pipelines from rubbing in the protective cover 911. The filler 917 may be a sponge, foam, etc., and the embodiment of the utility model does not limit the specific material of the filler 917.

[0091] In order to facilitate the collection of the armor cable 91, in one embodiment, the chassis 10 may be provided with an armor cable winding member 17, and when no welding is performed, the armor cable 91 may be wound around the armor cable winding member 17, thereby preventing the armor cable 91 from being randomly placed. Specifically, the armor cable winding member 17 may be provided on a side cover of the chassis 10.

[0092] In the embodiment of the utility model, a roller 16 may be installed at the bottom of the chassis 10, and the number of rollers 16 may be multiple and spaced apart. In this case, the laser welding machine is supported on the ground by the rollers 16, and the rolling of the rollers 16 during the displacement process can drive the entire laser welding machine to move, thereby making it more convenient for the user to perform the displacement operation of the laser welding machine.
