The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0063] like Figures 1 to 12 As shown, the present invention is an intelligent welding device for metal parts, comprising: a welding platform 1, a loading component 2 for conveying metal parts to the welding platform 1, a fixing component 3 for fixing the metal parts, a welding robot 4, an absorbing component 5 for absorbing smoke generated by welding, a unloading component for unloading after welding is completed, and a control system.

[0066] As an optional solution, the limiting groove 2432 is composed of two vertically arranged side plates 24321, a bottom plate fixedly installed at the bottom of the two side plates 24321, and a back plate 24322 slidably installed at the two side plates 24321, with a gap in the middle of the bottom plate; a sliding groove 24323 is opened on the side where the two side plates 24321 are close to each other, and the sliding groove 24323 gradually slopes downward from the axis of the separation plate 243 outward; a telescopic cylinder 245 is also installed at the bottom of the separation plate 243, and the piston rod of the telescopic cylinder 245 is fixedly connected with a connecting block 246, and the connecting block 246 passes through the gap at the bottom and is connected to the back plate 24322, so that when the piston rod of the telescopic cylinder 245 is extended, the back plate 24322 can be driven to extend outward through the connecting block 246, thereby The metal parts are pushed to the fixing component 3; optionally, the separation disk 243 is an inclined separation disk 243, and its end facing the feeding component 2 is higher than the end facing the welding platform 1, so that when the workpiece rotates to one end of the welding platform 1 along with the limiting groove 2432, it slides from the limiting groove 2432 to the welding platform 1; in addition, these two embodiments can also be combined with each other. For example, when the workpiece fails to slide out of the limiting groove 2432, the workpiece is pushed out by the telescopic cylinder 245; optionally, in this embodiment, the diameter of the separation disk 243 can also be enlarged, and the separation disk 243 can be set at a position close to the welding platform 1, so that during the rotation of the separation disk 243, the limiting groove 2432 can be rotated to the welding position on the welding platform 1, thereby facilitating welding.

[0067] The swinging member 242 includes: a transverse telescopic block 2421 which is slidably mounted on the guide member 241 and can be telescoped laterally, a vertical telescopic block 2422 which is slidably mounted on the guide member 241 and can be telescoped up and down, and a half gear 2423 which is rotatably mounted on one side of the guide member 241; the half gear 2423 can be connected to the double gear transmission on the roller 22 through a chain, or can be driven to rotate by an independent motor; the transverse telescopic block 2421 is provided with vertical connecting teeth meshing with the half gear 2423, and transverse connecting teeth meshing with the first gear 2434; the vertical telescopic block 2422 is provided with connecting teeth meshing with the half gear 2423; the transverse telescopic block 2421 and the vertical telescopic block 2422 are respectively fixedly connected with a reset member 2424, and when the transverse telescopic block 2421 or the vertical telescopic block 2422 is offset from the half gear 2423, the reset member 2424 drives the transverse telescopic block 2421 and the vertical telescopic block 2422 to reset;

[0068] When loading, the metal parts are poured directly onto the conveyor belt 21 from the storage tray or storage box. During the movement of the metal parts along the conveyor belt 21, the metal parts are gradually brought closer to the middle of the conveyor belt 21 through the guide member 241, and form a row to move toward the lower feeding end; then, the transverse telescopic block 2421 is extended under the drive of the half gear 2423, and is retracted under the action of the reset member 2424 when it is separated from the half gear 2423, thereby pushing the metal parts of the upper layer toward the upper feeding end to prevent the metal parts from being vertically accumulated on the unloading side of the swing member 242; the vertical telescopic block 2422 is extended under the drive of the half gear 2423, and is retracted under the action of the reset member 2424 when it is separated from the half gear 2423. When the vertical telescopic block 2422 is extended, it presses the metal parts of the lower layer; when the vertical telescopic block 2422 is retracted, the metal parts of the lower layer can pass through the vertical telescopic block 2422; thereby The metal parts intermittently pass through the vertical telescopic block 2422 and continue to move toward the lower material end; that is, through the extension and retraction of the vertical telescopic block 2422, the metal parts movement channel is opened or closed, so that the metal parts can intermittently pass through the vertical telescopic block 2422; when the horizontal telescopic block 2421 is retracted, it drives the first gear 2434 to rotate, and then drives the connecting shaft 2433 to rotate, thereby driving the separation disk 243 to rotate, so that the metal parts passing through the vertical telescopic block 2422 can slide into the limiting groove 2432 of the separation disk 243, and then rotate with the separation disk 243, driving the metal parts to rotate with the separation disk 243; when the metal parts are brought to one side of the welding platform 1, the telescopic cylinder 245 is started to drive the connecting block 246 to extend, thereby driving the back plate 24322 to extend outward, and tilt downward during the extension process, so that the metal parts move to the fixed component 3.

Optionally, the unloading assembly includes: a push block, and a power source for driving the push block to move; the unloading assembly can also be an unloading manipulator; it can also be manual unloading; in this application, the fixing assembly 3 and the unloading assembly are both common structures.

[0070] During the laser welding process, the high-energy laser beam will cause the metal material to melt rapidly and partially vaporize to form metal vapor. The metal vapor will condense into tiny metal particles during the cooling process, forming smoke. When laser welding is performed in air or a protective atmosphere, the molten metal may react with oxygen or other gases to form oxide particles, which will also exist in the form of smoke or particles. In order to protect the health of workers and avoid polluting the environment, it is necessary to treat the smoke generated by welding.

At the same time, the telescopic bevel block 51142 triggers the sensor 51143, and the fan-shaped piece 51141 is powered off. Then the fan-shaped piece 51141 continues to rotate and separates from the telescopic bevel block 51142. When separated, the telescopic bevel block 51142 is reset, triggering the sensor 51143. At this time, the fan-shaped piece 51141 is powered on and continues to adsorb metal particles.

[0075] The telescopic inclined block 51142 includes: an outer shell 511421, an inner shell 511422, and a return spring 511423 connecting the outer shell 511421 and the inner shell 511422; the sensor 51143 is installed between the outer shell 511421 and the inner shell 511422.
