[0048] The handheld laser welding machine involved in the present application comprises a main chassis 1, a quick-release connection assembly 11 and a peripheral chassis. Figures 1 to 7 As shown, a laser emitting component for emitting laser is provided in the main chassis 1; the peripheral chassis can be configured as a wire feeding chassis 2 in one case, as an air feeding chassis 3 in another case, and can be configured with a wire feeding chassis 2 and an air feeding chassis 3 in another case. Among them, the wire feeding chassis 2 is used to transmit welding wire, and the air feeding chassis 3 is used to transmit shielding gas, so as to cooperate with the laser emitting component to perform laser wire welding on the workpiece to be processed. In addition, the peripheral chassis can be detachably arranged on any side wall of the main chassis 1 through a quick-release connection component 11, for example: the top, bottom or side wall of the main chassis 1, to achieve quick disassembly and quick installation of the peripheral chassis, so as to facilitate user maintenance and replacement. In other words, the peripheral chassis of the present application is modularly designed, and can be integrated and installed on the main chassis 1, or taken out therefrom and used separately.

[0049] This solution improves the modularity and compatibility of the wire feeder, the protective gas equipment and the laser chassis, so that the equipment is more centralized. The user only needs to move one chassis during use, and can easily cooperate with the handheld welding gun 13 to complete the conversion of the processing scene, and there is no need to set up a long integrated armor cable 14; secondly, the user can configure according to actual needs, and freely combine the wire feeder chassis 2, the gas supply chassis 3 and the main chassis 1 to perform laser melting welding or laser wire filling welding. At the same time, the wire feeder chassis 2, the gas supply chassis 3 and the main chassis 1 can be used independently and can be used in conjunction with other chassis, 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.

[0050] In one embodiment, Figures 1 to 4 , Figure 6 and Figure 8As shown, the welding machine also includes a handheld welding gun 13 and an integrated armor cable 14. The two ends of the integrated armor cable 14 are respectively connected to the handheld welding gun 13 and the main box 1. A channel is provided in the integrated armor cable 14, and the channel is used to transmit the optical fiber of the laser emission component and the wires in the main box 1 to protect the optical fiber and the wires. At the same time, the integrated armor cable 14 has a certain strength and flexibility to prevent the user from directly pulling the main box 1 by dragging the integrated armor cable 14. At the same time, the integrated armor cable 14 is also convenient for winding and storage.

[0051] Optionally, there are no more than 5 channels in the integrated armored cable 14 for transmitting lasers and electrical signals output from the main chassis 1, and shielding gas and / or welding wire output from the peripheral chassis.

[0052] Now refer to Figures 1 to 4 , Figure 6 and Figure 7 , further explaining the specific implementation plan of the cooperation between the peripheral chassis and the main chassis 1.

[0053] In one embodiment, in one case, when the wire feeding box 2 is configured in the external box, a wire guide tube 21, a wire reel and a wire guide assembly for conducting the welding wire are provided in the wire feeding box 2. One end of the wire guide tube 21 is connected to the wire reel in the wire feeding box 2 under the conduction of the wire guide assembly, and the other end extends out of the wire feeding box 2 and is internally or externally placed relative to the integrated armored cable 14.

[0054] In other words, the wire guide tube 21 can be integrated inside the channel of the integrated armor cable 14, and fixed to the rear of the gun body 132 of the handheld welding gun 13 through the integrated armor cable 14 adapter, and then directly transmit the welding wire from the inside of the gun body 132 and the gun rod 131 to the surface of the workpiece to be processed. In another case, the wire guide tube 21 coming out of the integrated armor cable 14 adapter can transmit the welding wire from the outside of the gun body 132 and the gun rod 131 to the surface of the workpiece to be processed. At this time, a bracket can be set on the gun rod 131 or / and the gun body 132 to fix the wire guide tube 21 to ensure that the welding wire will not deviate during welding.

[0055] In another case, the wire guide tube 21 can be integrated and arranged outside the channel of the integrated armor cable 14 containing optical fiber, and then the welding wire is directly transmitted to the surface of the workpiece to be processed through the gun body 132 and the gun rod 131. In another case, a bracket can be set on the gun rod 131 or / and the gun body 132 to fix the wire guide tube 21, and the wire guide armor tube is directly transmitted from the external chassis to the bracket, which is external to the integrated armor cable 14 containing optical fiber and the handheld welding gun 13.

[0056] In one embodiment, when the external chassis is configured with a wire feeding chassis 2 and an air feeding chassis 3, one of the wire feeding chassis and the air source can be arranged inside the other, that is, one of the wire feeding chassis 2 and the air feeding chassis 3 is in a built-in relationship relative to the other.

[0057] In other words, in one case, the wire feeder box 2 can be integrated inside the housing of the gas feeder box 3, that is, the gas feeder box 3 can be used to output the shielding gas while also transmitting the welding wire for welding. In another case, the gas feeder box 3 can be integrated inside the housing of the wire feeder box 2, that is, the wire feeder box 2 can be used to transmit the welding wire for welding while also outputting the shielding gas.

[0058] Optionally, in the above two cases, the wire feeder box 2 and the air feeder box 3 can also be quickly released and quickly installed through the quick release connection assembly 11.

[0059] In one embodiment, when the peripheral chassis is equipped with a wire feeding chassis 2 and an air feeding chassis 3, the air feeding chassis 3 is detachably arranged on any side wall of the main chassis 1 through a quick-release connection component 11, that is, the wire feeding chassis 2 and the air feeding chassis 3 form a relatively external relationship, and the air feeding chassis 3 can be adjacent to, opposite to, or connected to the wire feeding chassis 2. Similarly, when the two form a relatively external relationship, the wire feeding chassis 2 and the air feeding chassis 3 can also be quickly removed and quickly installed through the quick-release connection component 11.

[0060] In one embodiment, the air feeding box 3 and the wire feeding box 2 can be quickly removed from the main box 1 and used independently relative to the main box 1, and can be used with other styles of main boxes 1 (ie, lasers, etc.).

[0061] In one embodiment, the air feeding box 3 and the wire feeding box 2 are combined and connected to form an integrated wire feeding and air feeding machine, which can be used independently of the main box 1. Although the prior art solves the flexibility and convenience problems of the handheld welding gun 13, the laser, wire feeder, and shielding gas equipment have always been heavy and unportable. The wire feeder and air feeder of the present application can be freely combined and cooperate with the main box 1 to form a modular, integrated, and highly compatible laser welding machine, which greatly improves the overall flexibility of the handheld laser welding equipment.

[0062] In one embodiment, when the external chassis is equipped with an air supply chassis 3, the air supply chassis 3 includes an air duct 31 and an air source, one end of the air duct 31 is connected to the air source of the air supply chassis 3, and the other end extends out of the air supply chassis 3 and is internally or externally placed relative to the integrated armored cable 14.

[0063] In other words, the air duct 31 can be integrated inside the channel of the integrated armor cable 14, and fixed to the rear of the gun body 132 of the handheld welding gun 13 through the integrated armor cable 14 adapter, and then directly transmit the shielding gas from the inside of the gun body 132 and the gun rod 131 to the surface of the workpiece to be processed. In another case, the air duct 31 coming out of the integrated armor cable 14 adapter can transmit the shielding gas from the outside of the gun body 132 and the gun rod 131 to the surface of the workpiece to be processed. In this case, a bracket can be set on the gun rod 131 or / and the gun body 132 to fix the air duct 31 to ensure that the shielding gas does not move during welding.

[0064] In one case, the air guide tube 31 can be integrated outside the channel of the integrated armor cable 14 containing the optical fiber, and then directly transmit the protective gas to the surface of the workpiece to be processed through the inside of the gun body 132 and the gun rod 131.

[0065] In one case, a bracket can be provided on the gun barrel 131 and / or the gun body 132 to fix the air duct 31. The air duct 31 is directly transmitted from the external chassis to the bracket. Compared with the integrated armor cable 14 containing optical fiber and the handheld welding gun 13, both are external. This embodiment can reduce the waste of protective gas, realize small flow gas use, and accurately control the airflow.

[0066] In another case, when the air duct 31 is built into the handheld welding gun 13, the corresponding air path and laser channel 134 are independently arranged or at least partially connected to each other, so as to achieve the effect of saving gas.

[0067] In addition, under the premise that the wire guide tube 21 and / or the air guide tube 31 are externally arranged relative to the integrated armor cable 14, the welding machine further includes a clamp 4 for positioning the integrated armor cable 14 and each tube to avoid the pipeline being scattered.

[0068] Further, one of the cases of the peripheral chassis may be as follows Fig.12 As shown, the gas source or welding wire reel can be quickly removed and installed from the top of the chassis shell, and a flap is provided at the corresponding top position. An opening can also be provided on the circumferential side wall of the chassis shell, and the gas source or welding wire reel can be quickly removed and installed from the opening.

[0069] like Fig.12 As shown, when the peripheral chassis is an air supply chassis 3, an air outlet interface 32, a wire outlet interface 33 and a wire outlet adapter interface are respectively provided on the top and bottom of the chassis shell, so that the wire guide tube 21 and the air guide tube 31 in each chassis can be smoothly connected to the inside of the main chassis 1, and then connected to the inside of the integrated armor cable 14, finally realizing the integration of the chassis, the armor cable and the handheld welding gun 13.

[0070] Furthermore, in order to ensure the miniaturization and lightness of the chassis, the volume of each peripheral chassis does not exceed one third of the main chassis, such as the volume of the air supply chassis 3 or the wire feeding chassis 2 does not exceed one third of the main chassis.

[0071] Optionally, a handle is provided on the top or rear side wall of the main chassis for the user to carry or hold the main chassis to move the entire main chassis.

[0072] Optionally, a shoulder strap may be provided on the top of the main chassis for the user to carry the device on his / her body. Whether in the moving process or the processing process, the user has a variety of moving modes to choose from.

[0073] For further information, please refer to Fig. 9 and Fig.10 The handheld welding gun 13 includes a gun body 132, a base 133 and a gun rod 131 which are connected in sequence. Fig. 9 , which is a schematic diagram of the wire guide tube 21 and / or the wire guide tube 21 being built in the gun barrel 131: wherein the gun barrel 131 is provided as one, and a wire outlet channel 136 and an air channel 135, which are independently provided or interconnected with each other, and a laser channel 134 are provided on the gun barrel 131 and the base 133. It can be further known that a docking groove 137 is provided on the end of the base 133 away from the gun barrel 131, so as to facilitate assembly with the gun body 132, so as to ensure the sealing of the air channel 135 and the laser channel 134.

[0074] Furthermore, the quick-release connection assembly 11 of one of the above-mentioned embodiments may also be used between the base 133 and the gun body 132 .

[0075] Further, Fig.10 , which is a schematic diagram of the wire guide tube 21 and / or the wire guide tube 21 being built in the gun rod 131 : wherein, there are multiple gun rods 131 , and two are taken as an example for explanation here.

[0076] The air channel 135 , the wire outlet channel 136 and the laser channel 134 are respectively arranged in one-to-one correspondence with the gun rods 131 ; or any two of them are arranged on the same gun rod 131 , and the two gun rods 131 are independent of each other and arranged at intervals.

[0077] It is worth noting that the wire outlet channel 136 and the laser channel 134 must be separated from each other to prevent the heat flux generated by the laser from penetrating the inner wall of the wire outlet channel 136 through the gun barrel wall and then melting the welding wire.

[0078] In one embodiment, there are multiple peripheral chassis, each of which is detachably arranged along one side of the main chassis 1, and two adjacent peripheral chassis are connected by a quick-release connection assembly 11. Alternatively, each peripheral chassis is arranged corresponding to a side wall of the main chassis 1. Figures 1 to 4 , Figure 6 and Figure 7 As shown, the peripheral chassis can be arranged in sequence along the vertical direction. Since a heavy wire reel is provided inside the wire feeding chassis 2 and a heavy air source is provided inside the air supply chassis 3, the weight is concentrated at the bottom of the main chassis 1 to increase the stability of the entire chassis.

[0079] Optionally, when the configuration weight of the peripheral chassis is less than that of the main chassis 1, the peripheral chassis is arranged on the top of the main chassis 1, and a handle is arranged on the upper part of the chassis.

[0080] In other embodiments, the peripheral chassis can be arranged in the circumference of the main chassis 1, for example, on one of the front, rear, left and right side walls of the main chassis 1, and correspondingly, evenly distributed moving wheels are arranged at the bottom of the main chassis 1 and the peripheral chassis to facilitate the movement of the entire chassis.

[0081] The quick-release connection assembly 11 in the above technical solution can be of the same structure or of different structures. The quick-release connection assembly 11 includes: one or more of a thread, an adapter, a rotary lock structure or a fastener.

[0082] In one case, if Fig.11 As shown, when the quick-release connection assembly 11 is set as a rotary lock structure, the quick-release connection assembly 11 includes a turn buckle 111 and an alignment slot column 112 that cooperate with each other. The turn buckle 111 is provided with a stopper, and the alignment slot column 112 is provided with a slot that matches the stopper around the circumference. The turn buckle 111 is set on the shell of one of the chassis. When the alignment slot column 112 is inserted into the slot of the turn buckle 111, the turn buckle 111 can be rotated so that the stopper is inserted into the slot on the alignment slot column 112, and then the two are locked. The alignment slot column 112 is set on the outer shell of one of the chassis, and the turn buckle 111 is set on the outer shell of another chassis connected thereto.

[0083] In one embodiment, a cooling line pipe is provided in the integrated armor cable, and the cooling line pipe can be used to provide cooling medium such as refrigerant and shielding gas for the laser emission assembly or the welding gun 13. When the cooling line pipe is used to transport shielding gas as the cooling medium, the cooling line pipe can be an air guide pipe.

[0084] The above embodiments of the present invention focus on the differences between the various embodiments. As long as the different features of the various embodiments are not contradictory, they can be combined to form more specific embodiments. Considering the simplicity of the text, they will not be repeated here.

[0085] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
