[0039] Furthermore, a cylinder assembly for assembling with a workpiece on a carrier is manually placed on the feeding device 3. The cylinder assembly is first placed on the feeding rail 12 of the feeding device 3. The feeding rail 12 transports the cylinder assembly to a pushing mechanism 13 installed on the feeding rail 12. When the inductive push plate 15 on the pushing mechanism 13 senses that a cylinder assembly is in place, the first drive 18 is started, so that the inductive push plate 15 pushes the cylinder assembly at that position on the feeding rail 12 toward the discharge port of the feeding rail 12. At the same time, the position sensor 16 located at the discharge port end of the feeding rail 12 senses that the cylinder assembly is in place.

[0040] Furthermore, the orienting device 4 is arranged on one side of the discharge port of the feeding device 3. After the aforementioned picking device 10 clamps the shaped cylinder assembly, it places the cylinder assembly on the correction seat 26 of the correction mechanism 25. The correction seat 26 has a precise positioning groove. The cylinder assembly is placed in the positioning groove to achieve further shaping, and the correction seat 26 is connected to the negative pressure adsorption component 28. The crank part is sucked by the negative pressure adsorption component 28, and the cylinder part is clamped and positioned by the correction clamp 27. The rotating mechanism 24 is powered by the motor to rotate 90°, and the correction mechanism 25 is rotated simultaneously with the rotation of the rotating mechanism 24, so that the cylinder assembly originally in a perpendicular relationship with the carrier track 9 is rotated to a position parallel to the carrier track 9, waiting for the clamping device 5 to pick up the material.

[0041] Furthermore, the sliding mechanism 30 on the clamping device 5 is started, and the slider 33 drives the jaw 31 installed thereon to slide along the slide rail 32, so that the jaw 31 slides to the top of the correction seat 26 after the turn, and the jaw 31 is lowered by the lifting drive 34. At the same time, the correction clamp 27 releases the cylinder part, and the jaw 31 clamps the cylinder assembly parallel to the carrier track 9. Then, the jaw 31 with the cylinder assembly is moved to the front of the crank riveting device 6 through the slider 33, and the cylinder assembly is transported to the top of the carrier track 9 of the carrier carrying the workpiece after oiling.

[0042] Further, when the clamping device 5 clamps the workpiece and moves to the front of the crank riveting device 6, the pressing mechanism 37 on the support frame 38 is started, and the support frame 38 is set above the carrier track 9 as a whole and fixedly installed on the frame 1, and the pressing mechanism 37 is set on the support frame 38 at a certain angle through the sliding seat 60 as a whole. The fourth drive 63 on the pressing mechanism 37 is started, and the guide block 61 set on the sliding seat 60 is pushed out in the direction of the carrier track 9 through the output shaft 64, so that the pressure rod 62 set at the bottom of the guide block 61 The first guide mechanism 36 starts to start, and the bending arm 56 on the mounting platform 53 of the first guide mechanism 36 pushes the connecting block 54 toward the direction of the carrier track 9, and the connecting block 54 drives the positioning guide mechanism 55 to be pushed toward the carrier track 9. Specifically, the positioning guide mechanism 55 includes a positioning plate 57, a third drive 58 and a plurality of guide pins 59, and the positioning plate 57 and the connecting plate 53 are connected. The blocks 54 are connected to each other. When the connecting block 54 is pushed out, the positioning plate 57 slides along its guide rail 71 to one side of the carrier track 9. The third drive 58 is started to push the guide pin 59 into the carrier track 9, so that the guide pin 59 is respectively inserted into the riveting holes of the assembled crank part and the workpiece that cooperate with each other, so that the cylinder assembly and the workpiece are positioned with each other. Subsequently, the material tray 46 on the material distribution assembly 43 on the first rivet conveying mechanism 35 conveys the rivets to its material distribution rail 47 through vibration. The material distribution rail 47 rivets the rivets one at a time or one at a time according to production requirements. The feeding is carried out in multiple ways, here there are two, the rivets are sent to the feeding block 51 by the fan through the tube body connected to the dividing rail 47 and the feeding block 51, and the feeding block 51 has a guide component 45 on one side. The rivets sent to the feeding block 51 are corrected by the correction block 52 of the guide component 45, and then the push rod 50 is pushed out by the second drive 49 located on the fixed seat 48, so that the push rod 50 can penetrate the corrected rivet in the feeding block 51 into the guide needle 59, so that the rivet can accurately enter the riveting hole of the positioned crank part and the workpiece that cooperate with each other.

[0043] Furthermore, the assembly part with rivets installed in the crank part is transported by the carrier along the carrier track 9 to the riveting mechanism 11 of the next processing unit of the crank riveting device 6. The riveting mechanism 11 includes a rotary riveting machine and a rotary riveting joint supporting mechanism coaxially arranged on both sides of the carrier track 9. The assembly part is supported by the rotary riveting joint supporting mechanism, and the rotary riveting machine completes the riveting of the rivet on the first riveting position on the crank part.

[0044] Furthermore, the crank riveted assembly is then sent to the cylinder positioning device 7 by the carrier track 9. At the same time, the adsorption component 28 on the other side of the riveting mechanism 11 is provided with a top block at the joint of the top cylinder part. The top block presses down to make the cylinder tilt up, and the adsorption component 28 sucks the cylinder part. The rotation direction selection device on the cylinder positioning device 7 is lowered on the slide rail 32 along with the slider 33 through the motor, and the orientation head 72 at the end of the rotating seat 68 is moved to the cylinder part, so that the cylinder part is clamped in the orientation head 72 and is connected to the rotating shaft 69 in the orientation head 72. Then, the servo drive is started, and the pulley 73 drives the rotating shaft 69 in the rotating seat 68 to rotate, and the rotating shaft 69 drives the cylinder part to rotate in the orientation head 72, so that the riveting holes on both sides of the orientation head 72 are rotated to be on the same axis with the elastic locating pins 74 on both sides of the interior of the orientation head 72. At this time, the elastic locating pins 74 in the orientation head 72 pop out and get stuck in the riveting holes on both sides of the cylinder part, thereby realizing the rotation orientation function of the cylinder. After the orientation is completed, the riveting mechanism 11 rivets the second riveting position on the crank part according to the above-mentioned operation.

[0045] Furthermore, after the riveting of the second riveting position of the crank portion is completed, the carrier is sent to the cylinder riveting device 8 with the carrier track 9, and the fifth drive 75 on the pressing and positioning mechanism 41 is started to push down the transmission block 76 arranged on the fixed frame 42. At the same time, the sixth drive 77 installed on the transmission block 76 descends in the direction of the carrier track 9 together with the transmission block 76. After descending to a certain stroke, the sixth drive 77 is started to make the pressure block 78 installed at the bottom of the transmission block 76 extend and press down, and the pressure block 78 presses the cylinder assembly as a whole into the workpiece. Then, the bending arm 56 on the mounting platform 53 of the second guide mechanism 40 pushes the connecting block 54 in the direction of the carrier track 9, and the connecting block 54 drives the positioning guide mechanism 55 to be pushed toward the carrier track 9. When the connecting block 54 is pushed out, the positioning plate 57 on the positioning guide mechanism 55 slides along its guide rail 71 to one side of the carrier track 9. The drive 58 is started, and the guide needle 59 is pushed out into the carrier track 9, so that the guide needle 59 is inserted into the riveting hole position where the cylinder part and the workpiece cooperate with each other after the directional assembly, so that the cylinder assembly and the workpiece are positioned with each other. Subsequently, the material tray 46 on the dividing assembly 43 on the second rivet conveying mechanism 39 conveys the rivet to its dividing rail 47 by vibration. The dividing rail 47 feeds the rivet in a single or multiple manner according to production requirements. Here, the rivet is sent to the feeding block 51 by a fan through a tube body connected to the dividing rail 47 and the feeding block 51. The feeding block 51 has a guide assembly 45 on both sides. After the rivet sent to the feeding block 51 is corrected by the correction block 52 of the guide assembly 45, the push rod 50 is pushed out by the second drive 49 located on the fixed seat 48, so that the push rod 50 inserts the corrected rivet in the feeding block 51 into the riveting hole where the cylinder part and the workpiece cooperate with each other after positioning.

[0046] Furthermore, after completing the operation, the workpiece with rivets on the cylinder part is sent to the riveting mechanism 11 behind the cylinder riveting device 8, and the rivets on the cylinder part are riveted by the rotary riveting machine. At this point, the production process of automatic riveting and assembly of the entire hinge is completed.
