At this time, the CCD component can take a picture of the workpiece and transmit the information to the inside of the cover assembly. The conveying assembly is controlled and operated by the cover assembly. The surface of the workbench 10 is installed with a cover assembly. Through the control panel inside the cover assembly, the full-automatic manipulator 40, the motor 20, the pressure head 504 and the welding head 60 are timely controlled to facilitate operation. The rotating table 201 drives the workpiece on the surface to perform circular motion, and the fully automatic manipulator 40 picks up the processed workpiece after the rotating table 201 rotates one circle. The evaluation components 202 are symmetrically arranged on both sides of the rotating table 201, and the evaluation components 202 are symmetrically arranged on both sides of the tooling component 206 on one side.

[0027] The workpiece is manually placed on the surface of the feeding belt 30. At this time, the photoelectric sensor 302 can detect the incoming material on the surface of the feeding belt 30 to prevent the workpiece from being stacked or lacking. At this time, the feeding belt 30 drives the workpiece on the surface to move and transport the workpiece. The CCD component 304 at this location takes a picture of the position of the workpiece, and the position of the workpiece is confirmed by the CCD component 304. The workpiece position information is transmitted to the fully automatic manipulator 40, and the fully automatic manipulator 40 drives the cylinder 401 and the magnet 402 to move. At this time, the magnet 402 is moved onto the workpiece. The control cylinder 401 starts, and the end of the cylinder 401 extends to push the magnet 402 downward, so that the magnet 402 adsorbs the workpiece, and the CCD component 304 continues to detect the workpiece. When the CCD component 304 detects that the workpiece is abnormally damaged, it is transported to the NG unloading flow line 305 by the fully automatic robot 40 to remove the defective workpiece. At this time, when the fully automatic robot 40 drives the workpiece to move above the CCD component 304, it needs to stay above the CCD component 304 for 0.5S, and the CCD component 304 is precisely positioned.

[0028] Embodiment 2: The high-precision four-station rotor welding machine with automatic incoming material sorting is convenient for one-piece processing of parts. The specific implementation method is as follows: The surface of the workbench 10 is installed with a connecting frame 506, and the surface of the connecting frame 506 is installed with an electric cylinder 50, and the end of the electric cylinder 50 is a shift plate 507, and the end of the shift plate 507 is connected to a pressure head 504, and a pressure sensor 501 is embedded on the surface of the shift plate 507, and a grating ruler 502 is installed on the surface of the shift plate 507, and the jig assembly 206 is installed around the surface of the rotating table 201, the feeding belt 30 and the fully automatic manipulator 40 are arranged on the same side of the evaluation assembly 202, and the positions of the feeding belt 30 and the discharge belt 301 are arranged correspondingly, and the two CCD assemblies 304 correspond to the feeding belt 30 and the discharge belt 301 respectively. The discharge transmission belt 301 is placed in the position, and the feeding transmission belt 30 and the discharge transmission belt 301, the feeding dust extraction port 602 are symmetrically arranged on both sides of the pressure head 504, and the end of the welding head 60 is arranged corresponding to the position of the pressure head 504, the component 206 is arranged corresponding to the position of the pressure head 504, and the jig component 206 is installed around the surface of the rotating table 201, the feeding transmission belt 30 and the full-automatic manipulator 40 are arranged on the same side of the evaluation component 202, and the positions of the feeding transmission belt 30 and the discharge transmission belt 301 are arranged correspondingly, and the two CCD components 304 are placed corresponding to the positions of the feeding transmission belt 30 and the discharge transmission belt 301 respectively.

[0029] The fully automatic manipulator 40 can drive the workpiece to move to the inside of the jig assembly 206. At this time, the bottom of the workpiece contacts the surface of the step block 207. At this time, the optical fiber sensor 205 can check the position of the workpiece. The optical fiber sensor 205 can detect whether the product is horizontal. When the position of the product is horizontal, the motor 20 is started, and the output shaft of the motor 20 drives the rotating table 201 to rotate. The rotating table 201 drives the position of the jig assembly 206 on the surface to rotate. At this time, the jig assembly 206 with the workpiece is moved to the bottom of the pressure head 504, and the motor 20 is turned off. At this time, the position of the workpiece is fixed, and the electric cylinder 5 is started. 0, the electric cylinder 50 drives the pressure head 504 to move downward through the shift plate 507, so that the end of the pressure head 504 presses the workpiece downward, and the workpiece is flattened at this time. During the pressing, the pressure sensor 501 can detect the pressure award of the pressure head 504 to prevent the pressure head 504 from causing damage to the workpiece. At this time, the grating ruler 502 can ensure the pressing accuracy and stability of the pressure head 504. After the flattening is completed, the electric cylinder 50 drives the position of the pressure head 504 to be restored. When flattening is performed at this position, the fully automatic manipulator 40 repeats the above instructions to place the new workpiece on the surface of the next jig component 206 of the jig component 206, and performs a cycle operation.

[0030] Embodiment 3: The high-precision four-station rotor welding machine with automatic incoming material sorting can automatically weld workpieces. The specific implementation method is as follows: A slide module 601 is installed on the surface of the workbench 10, and the end of the slide module 601 is connected to a welding head 60, and a dust extraction port 602 is embedded in the surface of the welding head 60, the evaluation components 202 are symmetrically arranged on both sides of the rotating table 201, and the evaluation components 202 are symmetrically arranged on both sides of the jig component 206 on one side, the position of the jig component 206 is corresponding to the position of the pressure head 504, and the feeding drive belt 30 and the discharging drive belt 301 are symmetrically arranged, the dust extraction port 602 is symmetrically arranged on both sides of the welding head 60, and the end of the welding head 60 is arranged corresponding to the position of one of the jig components 206.

[0031] At this time, the output shaft of the motor 20 drives the rotating table 201 to rotate, so that the rotating table 201 drives the workpiece on the surface to continue to rotate. When the workpiece rotates to the bottom of the welding head 60, it stops moving. At this time, the next slide module 601 of the slide module 601 drives the workpiece on the surface to move to the bottom of the pressure head 504. At this time, the slide module 601 drives the position of the welding head 60 to move up and down, so that the welding head 60 is closer to the surface of the published workpiece. At this time, the welding head 60 can weld the workpiece and perform all-round welding on the workpiece. Since the workpiece is placed on the surface of the step block 207, it can prevent the workpiece from being mistakenly welded with the jig assembly 206. When welding is performed at this location, the pressure head 504 can flatten the workpiece at the next slide module 601 of the slide module 601. When the welding head 60 is welding, the smoke purifier can be turned on through the control panel, and the air at the welding location is driven by the smoke purifier to enter the dust extraction port 602. At this time, the dust extraction port 602 transmits the smoke to the inside of the smoke purifier, and the masonry is purified and discharged through the smoke purifier.

[0032] Embodiment 4: The high-precision four-station rotor welding machine with automatic incoming material sorting drives the workpiece on the surface to rotate in a circular manner and removes the workpiece after processing. The specific implementation method is as follows: A motor 20 is installed inside the workbench 10, and the end of the output shaft of the motor 20 passes through the workbench 10 and is connected to a rotating table 201; evaluation components 202 are symmetrically arranged on the surface of the workbench 10, and the surfaces of the two evaluation components 202 are connected to optical fiber sensors 205, a cam divider 204 is arranged on the bottom surface of the rotating table 201, a jig assembly 206 is arranged on the surface of the rotating table 201, and the surface of the jig assembly 206 is connected to a step block 207, a feeding transmission belt 30 and a discharging transmission belt 301 are symmetrically arranged on the surface of the workbench 10, and a photoelectric sensor 30 is installed between the feeding transmission belt 30 and the discharging transmission belt 301.

[0033] The motor 20 continues to drive the rotating table 201 to rotate. After the rotating table 201 drives the jig assembly 206 to rotate one circle, the fully automatic robot 40 can remove the workpiece after welding from the surface of the jig assembly 206. At this time, the fully automatic robot 40 moves to the workpiece launcher. At this time, the workpiece is placed on the surface of the discharge conveyor belt 301 through the cylinder 401 and the magnet 402. The workpiece is transported by the discharge conveyor belt 301. At the same time, when the fully automatic robot 40 moves the workpiece, the CCD component 304 at this location detects the position of the workpiece, and controls the fully automatic robot 40 to place the workpiece on the surface of the conveyor belt 301 through the CCD component 304.

[0034] Working principle: By placing the workpiece on the surface of the feeding transmission belt 30, the position of the workpiece is sensed by the internal photoelectric sensor 302, and the position of the workpiece is adjusted. At this time, the CCD component 304 can take a picture of the workpiece and transmit the information to the inside of the full-automatic robot 40. The full-automatic robot 40 controls and operates the conveying of the workpiece. At this time, the full-automatic robot 40 prevents the workpiece from being on the surface of the jig assembly 206. The motor 20 drives the jig assembly 206 to rotate through the rotating table 201, and performs a circular motion on the workpiece on the surface of the jig assembly 206. The jig assembly 206 continuously transports the workpiece to the bottom of the pressure head 504 and the welding head 60, and the pressure head 504 flattens the workpiece, and the welding head 60 welds the workpiece. At the same time, the motor 20 drives the jig assembly 206 to rotate, and the full-automatic robot 40 can take out the welded workpiece and place a new workpiece on the surface of the jig assembly 206 for a cyclic motion.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

The fully automatic manipulator (40) grasps the workpiece by magnetic force, and the CCD component (304) simultaneously detects the position of the product, so that the fully automatic manipulator (40) can more accurately place the workpiece on the surface of the four-station rotating platform; Step 3: When the workpiece is placed on the surface of the rotating table (201), the optical fiber sensor (205) can detect the position of the workpiece, and at the same time, the rotating table (201) drives the workpiece on the surface to rotate. At this time, the workpiece can be moved to the bottom of the pressure head (504) and the welding head (60), and the surface of the workpiece is processed by the pressure head (504) and the welding head (60). After the workpiece is processed, the rotating table (201) drives the workpiece on the surface to rotate one circle. At this time, the fully automatic robot (40) can take out the processed product, place it on the surface of the discharge conveyor belt (301), and transport the workpiece out through the discharge conveyor belt (301).
