Description

Technical Field

[0001] The invention relates to annular component welding, in particular to an automatic welding device for annular components. Background Art

[0002] In the prior art, annular components are formed by bending or other processes of long strip components to form annular components with notches, and then welding the two ends of the annular components together to form a complete annular component. However, when welding annular components, the two ends need to be completely aligned before welding to avoid the problem of deviation in the connection of the two ends. If the two ends are not aligned, there will be some problems after welding. First, the shape of the annular component will change, the size of the inner ring and the outer ring will deviate, and the roundness deviation will be large. Therefore, when welding, the two ends are mostly aligned manually and then welded by a welding machine, which is difficult to produce automatically. However, this manual control method has cumbersome positioning, extremely low processing efficiency, high labor intensity and high cost. Especially for annular components such as wave springs, due to their inherent wavy shape, the height difference of the waves makes it more difficult to align the ends. Therefore, it is more difficult to accurately position the ends of the wave spring, making it difficult to ensure the quality of welding and the quality of the processed wave spring, resulting in a high rejection rate. To this end, an automatic welding device for annular components is proposed. Summary of the Invention

The top camera 272 and the bottom camera 273 photograph and detect the upper and lower sides of the welded part, thereby improving the detection accuracy.

[0023] In one embodiment, it further includes an output mechanism 28 for outputting the processed annular member and a blanking mechanism 29 installed on the chassis 1 for grasping the annular member completed welding on the clamping tooling 24 and moving it to the output mechanism 28; The described blanking mechanism 29 includes a blanking frame 291, a manipulator 292 installed on the blanking frame 291, a grasping frame 293 installed on the manipulator 292, a plurality of grasping cylinders 294 installed on the grasping frame 293, and clamping jaws 295 installed on the grasping cylinders 294; the manipulator 292 is used to drive the grasping frame 293, the grasping cylinders 294, and the clamping jaws 295 to move, and the grasping cylinders 294 are used to drive the clamping jaws 295 to clamp or release the annular member; The described output mechanism 28 includes an output frame 281, rollers 282 installed on the output frame 281, a conveyor belt 283 installed on the rollers 282, and an output motor 21 for driving the rollers 282 to rotate and drive the conveyor belt 283 to act; the output motor 21 drives the rollers 282 to rotate, and during the rotation process, the rollers 282 drive the conveyor belt 283 to act and drive the annular member to be output; a non-conforming product recycling bin can also be set beside the output frame 281. During the detection process, when it is detected that the welding position is inaccurate, the welding is not firm after welding, and the annular member with deviation problems in the welding position is grabbed by the manipulator 292 and dropped into the non-conforming product recycling bin when blanking, and only the annular member that passes the detection is transported to the conveyor belt 283 of the output mechanism 28 by the manipulator 292 for output.

[0024] Through the setting of the blanking mechanism 29, after the manipulator 292 drives the grasping frame 293 and the clamping jaws 295 to remove the annular member that has completed welding and detection, it is first moved to the bottom camera 273, and the bottom of the annular member is photographed by the bottom camera 273, and then it is moved to the conveyor belt 283 of the output mechanism 28 for output.

Then, by setting the notch positioning part 354, when stacking a number of annular components, the opening groove on the annular component is clamped on the notch positioning part 354 to limit the circumferential position of the annular component on the tooling base 351, ensuring that when the annular component is grabbed onto the clamping tooling 24 by the feeding mechanism 4, the notch of the annular component can be limited to the set position.

[0029] The working process of the present invention: The operator only needs to stack a number of annular members (the annular members in this embodiment are wave springs) on the turntable tooling 35 of the material storage 3; both the video display one and the video display two in the present invention can use a computer and a display; During processing, the servo drive system 42 drives the moving frame 43 to move above the turntable tooling 35 at the loading position of the material storage 3, and then controls the loading cylinder 44 to drive the gripping frame 293 to move downward to the material taking position. Then, the gripping cylinder 294 is controlled to drive the gripper 295 to clamp the wave spring, and then the loading cylinder 44 is controlled to reset. Then, the servo drive system 42 drives the moving frame 43 to move above the clamping tooling 24, and then controls the loading cylinder 44 to drive the wave spring to move downward onto the clamping tooling 24, and then the gripper 295 is released to place the wave spring on the carrier upper plate one 242 and the carrier upper plate two 243 of the clamping tooling 24, and at the same time, the opening grooves at the joints at both ends of the wave spring are stuck at the ejector fork 249 and then reset to prepare for the loading of the next wave spring; The control system controls the clamping cylinder 245 to start. The clamping cylinder 245 drives the upper carrier plate two 243 to move, driving the outer stopper 244 to push the wave spring until the outer stoppers 244 on the upper carrier plate one 242 and the upper carrier plate two 243 clamp the wave spring. Then the positioning cylinder 246 is started. The positioning cylinder 246 drives the positioning member 247 to press against the inner sides of both ends of the wave spring. Then the lateral movement cylinder 251 is started. The lateral movement cylinder 251 drives the pull plate cylinder 253 and the clamping jaw cylinder 255 to move to the set position. Then the clamping jaw cylinder 255 is started. The clamping jaw cylinder 255 drives the clamping jaw 256 to press against the outer sides of both ends of the wave spring, realizing the limitation of the inner and outer positions of both ends of the wave spring. Then the pull plate cylinder 253 is started. The pull plate cylinder 253 drives the pull plate 254 to move downward. The pull plate 254 forms a downward extrusion force on both ends of the wave spring, making the bottoms of both ends of the wave spring fit with the adapter support member 6, so that the positions of both ends of the wave spring are completely aligned. Then control the ejector cylinder 248 to drive the ejector fork 249 to reset, exposing the joint of both ends of the wave spring; Then control the motor 21 to start. The motor 21 drives the divider 22 to act. The divider 22 drives the turntable 23 to rotate the moving station, driving the wave spring to move to the detection mechanism 26. The control system controls the camera 262 to take a picture of the joint of the wave spring. The taken image is sent to the video display one 264 and aligned with the set standard image in the video display one 264 to determine whether the positioning of the wave spring is accurate and send the information to the control system, If the detection is qualified, normal work is carried out. If the detection is unqualified, the control system controls the subsequent welding machine 56 not to weld the wave spring until the manipulator 292 removes the wave spring during blanking and places it in the unqualified product recycling bin; After the wave spring with qualified detection moves to the welding station along with the turntable 23, the control system controls the welder 5 to drive the welding machine 56 to move to the welding position and weld the joint of both ends of the wave spring; After welding is completed and moves to the finished product detection position along with the turntable 23, the control system controls the top camera 272 to take a picture of the welded parts at both ends of the wave spring. The taken image is sent to the video display two 271 and compared with the standard image in the video display two 271, and the detection result is sent to the control system. If the detection is qualified, normal work is carried out. If the detection is unqualified, the control system controls the subsequent manipulator 292 to remove the wave spring during blanking and place it in the unqualified product recycling bin; After the turntable 23 drives the wave spring to rotate to the blanking position, the control system releases the clamping of the wave spring by the clamping tooling 24, controls the manipulator 292 to drive the grasping cylinder 294 and the clamping jaw 295 to grasp the wave spring and move to the bottom camera 273. The bottom camera 273 takes a picture of the bottom of the welded part of the wave spring and sends it to the video display two 271 for comparison with the set standard image; If the detection is qualified, the manipulator 292 will move the wave spring onto the conveyor belt 283 and then release the clamping jaw 295, dropping the wave spring onto the conveyor belt 283 for output. If the detection is unqualified, the wave spring will be put into the recycling bin for unqualified products. During the working process, set the continuous unqualified quantity n. When the continuously detected unqualified quantity reaches n during the actual working process, the control system controls the entire device to stop working and wait for the staff to carry out maintenance and repair.
