[0057] In this specific embodiment, in order to improve the efficiency of the overall spring riveting process, each corresponding station adopts a double-station working mode.

[0058] When the present invention is working, first, the iron sheet vibration disk device 6 and the iron sheet feeding device 7 cooperate to transfer the iron sheet from the iron sheet vibration disk device 6 to the iron sheet feeding device 7. Specifically, the iron sheet slides from the vibration disk 62 along the iron sheet slideway 65 and moves to the middle of the iron sheet feeding device 7 through the straight vibration track 63. After arriving at the iron sheet feeding device 7, it is respectively located on both sides of the pushing manipulator 72. At this time, the pushing manipulator 72 on the iron sheet feeding device 7 pushes to the left and right sides, pushing the iron sheet to the iron sheet rotation position 75 respectively. Driven by the internal cylinder, the rotating gear 76 rotates the iron sheet rotation position 75 by 90 degrees, and the iron sheet rotation position 75 will be aligned with the iron sheet chute 821 on the riveting fixture 82. Then, the pushing cylinder 73 controls the pushing block 74 to move forward, pushing the iron sheet along the iron sheet chute 821 to the riveting fixture 82, and the iron sheet is located directly below the spring clamping block 822.

[0059] Under the action of the internal driving cylinder of the indexing turntable 83, the turntable 83 drives the riveting fixture 82 to rotate and comes to the bottom of the fixture alignment device 5. At this time, the positioning pin 52 moves downward to determine whether the positioning pin 52 is just inserted into the positioning hole 824. If it is inserted accurately, it works normally and continues to work at the next station, otherwise it stops automatically and waits for adjustment. Under normal working conditions, the riveting fixture 82 continues to move forward. At this time, it comes to the bottom of the spring corner device 4. Since the spring corner device 4 is the station for completing the preliminary fitting of the iron sheet and the spring, before the riveting fixture 82 comes. The spring corner device 4 needs to complete the following work at the same time, that is, cooperate with the spring taking device 3 to complete the preparation for placement of the spring. Specifically, the spring enters from the material receiving device 33, passes through the rotator 35 inside it, and the rotator 35 rotates 180 degrees to ensure that the end of the spring with the notch is facing down and the end with the horizontal bar is facing up, and then falls into the spring placement position 34. With the cooperation of the stepping feeding device 32 , the spring moves along the direction of the spring corner device 4 .

[0060] When the spring reaches the spring corner device 4, the first clamp 43, under the control of the lifting cylinder 42, clamps the spring downwards and places it on the second clamp 48. The second clamp 48 places the spring in the positioning pin 410. The notch at the bottom of the spring just matches the positioning pin 410. After the positioning pin 410 rotates a certain angle, the direction of the notch at the bottom of each spring can be guaranteed to be consistent. After that, the third clamp 47 moves the spring to the riveting fixture 82, so that the notched part at the bottom of the spring and the raised part in the middle of the iron sheet are fitted together, completing the preparation for the first step.

[0061] After the preparation work is completed, the riveting fixture 82 is moved to the station of the spring cross bar detection device 10. At this time, the optical fiber sensor 102 detects the position of the cross bar on the spring and sends the detection result to the next station.

[0062] After entering the spring riveting device 9 station, the riveting rod 95 and the riveting head 96 rotate the angle according to the detection result of the previous station, so as to avoid the horizontal bar on the spring. Under the drive of the cylinder, the riveting head 96 is pressed down to rivet the spring and the iron sheet together. After the riveting is completed, the finished product is transported to the spring finished product stacking mechanism 2. The material taking manipulator 25 grabs the finished spring. At this time, the indexing turntable fixture 84 located on the fixed plate 85 is pushed out in the direction of the riveting fixture 82, and the spring release block 823 is pushed into the inside of the riveting fixture 82. Then, the spring clamping block 822 releases the spring under the action of the wedge structure, so that the finished spring is grabbed and placed on the material plate 22 under the action of the manipulator. The material plate 22 moves forward little by little under the cooperation of the conveyor belt and the loose plate cylinder on the spring finished product stacking mechanism 2. The material plate 22 filled with finished springs is stacked and stacked one by one under the action of the stacking cylinder 24, which is convenient for subsequent loading and shipping.

[0063] Embodiment 2:

[0064] This embodiment is an expansion based on the first embodiment. Based on the first embodiment, the corresponding spring bar detection device 10 can be used as an omitted component, that is, the automatic riveting function is directly realized only by the spring riveting device 9. In this specific real-time mode, since the spring bar is not detected in the previous work, when the spring riveting step is performed, the first step is to press the rivet head 96 directly downward. Since there is a gap in the rivet head 96, there are two situations in the direction of the gap when it moves downward. One is that the bar is not aligned directly with the gap on the rivet head 96, and the spring can be pressed down directly, which belongs to normal operation. When there is a bar that is not aligned with the gap on the rivet head 96, the spring will be pressed down to form a certain deformation. At this time, the spring deformation is controlled within a certain range, and there will be no certain loss to the elasticity of the spring. Then the rivet head 96 will move upward again, complete the second downward pressure, complete the alignment operation of the bar, and then the riveting work of the spring and the iron sheet can be completed directly. In this way, the process of omitting a work station is realized, and the entire riveting process is more direct and efficient.

[0065] The above implementation modes are only used to illustrate the present invention, but not to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention.
