The following illustrates the method of use of the present invention:
step one: expansion ring error-proof limit and assembly expansion ring
The transfer and feeding servo motor 292 controls the movement of the manipulator 26 by driving the screw rod 291, and the movement of the piston between each station is realized by grabbing and releasing the piston by the manipulator 26. When the piston moves to the first station 10, the limiting cylinder 52 acts to push the expansion ring error preventing port 53 to move to the position shown in fig. 4, the feeding servo motor 71 outputs power through the feeding screw rod 66 and drives the lower flange plate 65 through the feeding screw rod 66, the lower flange plate 65 pushes the upper flange plate 62 to move upwards, so that the expansion ring is pushed to feed, the expansion ring is expanded through the structure when passing through the tail end of the material rod 67, and the expansion ring just falls into a groove of the piston after falling off from the material rod 67.
Step two: fitting skirt wiper blade
The manipulator 26 grabs the piston and moves to the second station 20, the manipulator 26 grabs the piston and is positioned through the A face of the piston, and the tail end of the manipulator 26 is coplanar with the B face of the piston.
The electromagnetic switch is turned on, and the electromagnetic coil 82 is energized, and a ring-shaped magnetic force is generated around it. The expanding ring floats under the action of annular magnetic force, at the moment, the central axis of the expanding ring is just coincident with the central axis of the electromagnetic coil 82, the electromagnetic switch is closed, the expanding ring is adsorbed instantly under the action of peripheral strong magnetic force, and the expanding ring is tightly attached to the C surface of the piston.
The robot 26 is depressed to push the piston and the rod 67 of the skirt wiper down through the a-face of the piston, at which time the skirt wiper is immobilized with the rod support post 81 of the skirt wiper. As the robot 26 continues to press down, the topmost skirt wiper is ejected, losing the expansion of the rod 67 of the skirt wiper, which resumes its original size, falling into the groove of the piston.
Step three: assembly head wiper blade
The manipulator 26 grabs the piston and moves to the third station 30, the manipulator 26 grabs the piston and is positioned through the A face of the piston, and the distance between the tail end of the manipulator 26 and the C face of the piston is 0.3mm.
The electromagnetic switch is turned on, and the electromagnetic coil 82 is energized, and a ring-shaped magnetic force is generated around it. The expanding ring and the skirt scraping piece float and separate under the action of annular magnetic force, at the moment, the central axes of the expanding ring and the skirt scraping piece are just coincided with the central axis of the electromagnetic coil 82, the electromagnetic switch is closed, and the expanding ring is instantly adsorbed under the action of peripheral strong magnetic force and is tightly adhered to the B surface of the piston.
The manipulator 26 is pressed down, the piston and the rod 67 of the head wiper are pushed to move downwards by the A face of the piston, and at the moment, the head wiper and the rod supporting column 81 of the head wiper are not moved. As the robot arm 26 continues to press down, the topmost wiper loses the expansion of the rod 67, resumes its original size, and falls into the slot of the piston.
Step four: assembling the second ring
The mechanical arm 26 grabs the piston onto a material rod 67 of the second ring, the feeding servo motor 71 outputs power through the feeding screw rod 66 and drives the lower flange plate 65 through the feeding screw rod 66, the lower flange plate 65 pushes the upper flange plate 62 to move upwards, and therefore the second ring is pushed to be fed, the structure of the second ring is expanded when the second ring passes through the tail end of the material rod 67, and the second ring just falls into a groove of the piston after falling off from the material rod 67.
Step six: assembling a first ring
The mechanical arm 26 grabs the piston onto a material rod 67 of the first ring, the feeding servo motor 71 outputs power through the feeding screw rod 66 and drives the lower flange plate 65 through the feeding screw rod 66, the lower flange plate 65 pushes the upper flange plate 62 to move upwards, and therefore the first ring is pushed to be fed, the first ring is expanded in structure when passing through the tail end of the material rod 67, and the first ring falls into a groove of the piston after falling off from the material rod 67.
The foregoing description is only illustrative of the preferred embodiments of the present invention and is not to be construed as limiting the scope of the invention, and it will be appreciated by those skilled in the art that equivalent substitutions and obvious variations may be made using the description and illustrations of the present invention, and are intended to be included within the scope of the present invention.
