[0031] See also Figure 1 and Figure 2, the welding mechanism 100 provided in the embodiment of the present application is now described. The welding mechanism 100 provided in the embodiment of the present application includes a base 190, a movable adjustment component 110, a welding component 120, a wire feeding component 130 and a loading component 140, wherein the movable adjustment component 110 is arranged on the base 190; the welding component 120 includes a connecting seat 121 and a laser welding head 122, the laser welding head 122 is rotatably connected to the connecting seat 121, the connecting seat 121 is arranged on the movable adjustment component 110, and the movable adjustment component 110 can move and adjust the position of the connecting seat 121 in three-dimensional space; the wire feeding component 130 includes a wire drawing piece 131 for straightening the welding wire and a wire feeding nozzle 132 for guiding the output of the welding wire, and the wire drawing piece 131 and the wire feeding nozzle 132 are sequentially provided for the wire feeding device 140. The wire drawing piece 131 is relatively fixed to the connecting seat 121, the wire feeding nozzle 132 is relatively fixed to the laser welding head 122, and the wire feeding direction of the wire feeding nozzle 132 intersects with the light emitting direction of the welding head; the loading assembly 140 is arranged on the base 190, and the loading assembly 140 is rotatable relative to the base 190, and the loading assembly 140 is used to carry the product to be welded; wherein, the moving adjustment assembly 110 adjusts the three-dimensional spatial position of the connecting seat 121, thereby synchronously adjusting the three-dimensional spatial position of the laser welding head 122, and combined with the rotation adjustment of the laser welding head 122 relative to the connecting seat 121, the intersection of the light emitting direction of the laser welding head 122 and the wire feeding direction of the wire feeding nozzle 132 corresponds to the to-be-welded position of the product to be welded.

[0032] In the welding mechanism 100 of the embodiment of the present application, the base 190 serves as the structural foundation of the welding mechanism 100 and provides structural stability; the movable adjustment component 110 is used to move and adjust the position of the welding component 120 in three-dimensional space to adjust the welding component 120 to a desired processing position; the connecting seat 121 of the welding component 120 serves as a structural setting carrier of the laser welding head 122, the connecting seat 121 is connected to the movable adjustment component 110, and the laser welding head 122 is rotatably connected to the connecting seat 121 and can be used to adjust the angle of the laser welding head 122, and cooperate with the movable adjustment of the movable adjustment component 110, so that the laser welding head 122 can be used for welding. The wire feeding nozzle 132 of the wire feeding assembly 130 is used to guide the welding wire to the laser path emitted by the laser welding head 122, so that the laser melts the welding wire for welding products, and a wire supply can be set between the wire drawing piece 131 of the wire feeding assembly 130 and the welding wire supply source, and the wire drawing piece 131 is used to supply the straightened welding wire to the wire feeding nozzle 132, so as to improve the supply accuracy of the welding wire; the loading assembly 140 is used to carry and position the products to be welded, and the loading assembly 140 rotates relative to the base 190 to adjust the angle of the products to be welded relative to the laser welding head 122, so that the laser welding head 122 can weld the corresponding rotary welds on the rotary products.

[0033] Among them, before welding, after the product to be welded is placed on the carrier assembly 140 for positioning, the moving adjustment assembly 110 is controlled to move the laser welding head 122 to the desired processing position, and the laser welding head 122 is controlled to rotate relative to the connecting seat 121 to adjust the processing angle of the laser welding head 122, so that the laser emitted from the laser welding head 122 can be emitted to the weld to be welded of the product to be welded; during the welding process, the laser emitted from the laser welding head 122 melts the welding wire delivered by the wire feeding nozzle 132 to the weld of the product, and the molten welding wire is used to weld the product. At the same time, the carrier assembly 140 cooperates to rotate so that the rotary weld is gradually completed by welding.

[0034] By using the mobile adjustment component 110 and the rotatable laser welding head 122, the laser welding head 122 can adjust the processing angle positioning based on the positioning in three-dimensional space, so that it can be used to weld welds in various positions and angles, thereby improving the versatility of welding; at the same time, the method of using molten welding wire for welding, compared with the method of using laser to make the product self-melting welding, the welding of molten welding wire can help reduce the deformation caused by the high temperature generated by the direct absorption of laser by the product, and improve the accuracy of the product obtained after welding. Therefore, the welding mechanism 100 scheme of the present application can be used for the welding of various rotary products and welds at various angles, with high versatility, and can also ensure that the precision of the welded product is high.

[0035] It should be noted that the movable adjustment component 110 in the embodiment of the present application can be any component structure that can move and adjust the three-dimensional spatial position of the welding component 120, for example, it can be a mechanical arm, or a setting that cooperates with multiple drive modules to achieve three-dimensional spatial adjustment, etc. The rotatable connection between the laser welding head 122 and the connecting seat 121 can be a single-axis rotation setting or a multi-axis rotation setting; similarly, the rotatable setting of the material loading component 140 relative to the base 190 can be a single-axis rotation setting or a multi-axis rotation setting, which depends on actual needs and is not limited.

[0036] In addition, when the weld seam settings of the product to be welded are different, the welding effect achieved by the welding mechanism 100 provided in the embodiment of the present application is also different. For example, if the weld seam of the product to be welded reaches a certain width, the molten welding wire can enter deeper into the product along the weld seam, thereby achieving a deeper welding depth and a more solid welding.

[0037] Furthermore, a first direction, a second direction and a third direction are defined. The first direction, the second direction and the third direction respectively have an angle and constitute a three-dimensional space direction, wherein the first direction is recorded as X, the second direction is recorded as Y, and the third direction is recorded as Z.

[0038] See also Figure 1 and Figure 2In the embodiment of the present application, the mobile adjustment component 110 includes a first drive component 111, a second drive component 112 and a third drive component 113 as an example, wherein the first drive component 111 is arranged on the base 190, the second drive component 112 is connected to the first drive component 111 by driving, and the first drive component 111 can drive the second drive component 112 to move along the first direction; the third drive component 113 is connected to the second drive component 112 by driving, and the second drive component 112 can drive the third drive component 113 to move along the second direction; the connecting seat 121 is connected to the third drive component 113 by driving, and the third drive component 113 can drive the connecting seat 121 to move along the third direction. The first drive component 111, the second drive component 112 and the third drive component 113 can be any setting that satisfies the driving control of the movement of the welding component 120. In the embodiment of the present application, the first drive component 111, the second drive component 112 and the third drive component 113 are used as a drive module as an example, which can provide higher driving accuracy and help improve the positioning accuracy of the welding component 120.

[0039] See also Figure 3 The welding assembly 120 in the above embodiment may also include a detection member 123, which is connected to the laser welding head 122. The detection member 123 is used to detect and identify the welding position of the product to be welded to assist the laser welding head 122 in welding positioning.

[0040] The detection member 123 in the embodiment of the present application takes the detection image as an example, and the laser welding head 122 adjusts the position according to the weld position of the product to be welded detected by the detection member 123 to achieve precise welding. The detection member 123 is connected to the laser welding head 122, which can be directly connected or indirectly connected using an intermediate connecting member, so as to move synchronously with the laser welding head 122, which helps to associate and cooperate in functions. The embodiment of the present application takes the relative fixed setting of the detection member 123 and the laser welding head 122 as an example, but it should be noted that regarding the relative fixed setting of the detection member 123 and the laser welding head 122, the detection member 123 can be connected to the laser welding head 122 in an adjustable installation manner to facilitate correction and adjustment during installation, and during operation, the detection member 123 and the laser welding head 122 are relatively fixed.

[0041] See also Figure 2 The welding mechanism 100 in the above embodiment may also include a wire cutting piece 150, which is arranged on the base 190 and is used to cut off the molten nodule at the free end of the welding wire; controlling the movement of the laser welding head 122 can enable the welding wire to pass through the free end of the wire feeding nozzle 132 and move to the cutting position of the wire cutting piece 150.

[0042] The wire cutting piece 150 can cut the welding wire. After the welding wire is used for one welding, the free end of the welding wire passing through the wire feeding nozzle 132 is cooled to form a molten nodule. By controlling the movement of the laser welding head 122, the free end of the welding wire passing through the wire feeding nozzle 132 can be moved to the cutting station of the wire cutting piece 150. The wire cutting piece 150 is used to cut off the molten nodule on the free end of the welding wire so that the molten nodule will affect the welding quality and the aesthetic appearance of the welding trajectory when it is used for welding next time.

[0043] See also Figure 4 The welding mechanism 100 in the above embodiment may further include a heating element 160. The heating element 160 may be arranged to heat the loading station of the loading assembly 140 to heat the product to be welded placed at the loading station.

[0044] The heating element 160 in the embodiment of the present application can be set as long as it can meet the needs of heating the products to be welded at the loading station, and there is no limitation on the specific setting position, for example, it can be adjustable and set on the base 190, or it can be set on the loading assembly 140 or on the loading assembly 140. The heating element 160 is used to heat the products to be welded, so as to preheat the products before welding, which helps to improve the welding quality.

[0045] Furthermore, the welding mechanism 100 may further include a temperature measuring component 170 , which may be arranged to measure the temperature of the loading station of the loading assembly 140 to detect the surface temperature of the product to be welded placed at the loading station.

[0046] The temperature measuring element 170 in the embodiment of the present application can be set as long as it can meet the requirements of detecting the temperature of the product to be welded at the loading station, and there is no limitation on the specific setting position, for example, it can be adjustable and set on the base 190, or it can be set on the loading assembly 140 or on the loading assembly 140. The temperature measuring element 170 is used to measure the temperature of the product to be welded, so as to feedback control the heating operation of the above-mentioned heating element 160. For example, in the welding process, the product to be welded needs to be preheated to temperature T. When the temperature measuring element 170 detects that the temperature of the product rises to temperature T, the heating element 160 is controlled to stop, which helps to accurately control the preheating temperature of the product.

[0047] See also Figure 1 , Figure 2 and Figure 4, the welding mechanism 100 in the above embodiment may also include a press-fitting assembly 180, the press-fitting assembly 180 includes a press-fitting frame 181 and a press-fitting part 182, the press-fitting frame 181 is arranged on the base 190, the press-fitting part 182 can be rotatably arranged on the press-fitting frame 181, and the rotation center axis of the carrier assembly 140 and the rotation center axis of the press-fitting part 182 can be arranged to overlap, that is, the carrier assembly 140 and the press-fitting part 182 in the embodiment of the present application can be adjusted from the corresponding rotation center axis to the overlap state as needed. It can be understood that when the rotation center axis corresponding to the carrier assembly 140 and the press-fitting part 182 is in the overlap state, the corresponding product to be welded is in the welding station, which can be used to cooperate with the laser welding head 122 to complete the welding process of the product; and when the rotation center axis corresponding to the carrier assembly 140 and the press-fitting part 182 is in the non-overlapping state, the corresponding product to be welded is outside the welding station, for example, located at the loading and unloading station, so as to load and unload.

[0048] See also Figure 5 , wherein the carrier assembly 140 may also include a carrier 141, a mounting seat 142, a first driving member 143 and a transmission member 144, the mounting seat 142 is arranged on the base 190, the first driving member 143 is arranged on the mounting seat 142, the first driving member 143 is drivingly connected to the transmission member 144, the transmission member 144 is drivingly connected to the carrier 141, and the carrier 141 is rotatable relative to the mounting seat 142; when the rotation center axis of the carrier 141 coincides with the rotation center axis of the press-fitting member 182, the first driving member 143 drives the transmission member 144 to drive the carrier 141 to approach or move away from the press-fitting member 182 along the direction of the rotation center axis of the carrier 141.

[0049] The mounting seat 142 serves as a structural carrier for the material carrier 141, the first driving member 143 and the transmission member 144. The mounting seat 142 can be fixedly mounted on the base 190 or can be movably mounted on the base 190. In the embodiment of the present application, the mounting seat 142 can be movably mounted on the base 190 as an example, so as to realize the mobile product as described above, and the product can be moved to different workstations by moving the mounting seat 142. The first driving member 143 drives the transmission member 144, thereby driving the material carrier 141 to approach or move away from the press-fitting member 182 along the direction of the rotation center axis of the material carrier 141. Of course, the first driving member 143 can also directly drive the material carrier 141 to move. The use of the transmission member 144 in the embodiment of the present application can help reduce the difficulty of the structural setting of the material carrier 141 being rotatable relative to the mounting seat 142, and at the same time help to realize the drive control of the movement and rotation of the material carrier 141 respectively. The first driving member 143 in the embodiment of the present application takes an electrical driving member as an example, so that in conjunction with an automated control system, it is possible to calculate the torque of the first driving member 143 through current, and then obtain the force exerted by the first driving member 143 on the product, which helps to understand the stress state of the product.

[0050] When the first driving member 143 drives the carrier 141 to approach the pressing member 182 along the direction of the rotation center axis of the carrier 141, the product to be welded placed on the carrier 141 can be brought into contact with the pressing member 182. When the force exerted by the first driving member 143 on the product to be welded reaches the set value, the first driving member 143 stops driving, so that the product to be welded maintains the current stress state. At this time, the carrier 141, the product to be welded and the pressing member 182 can rotate synchronously to cooperate with the laser welding head 122 for welding processing of rotating products.
