[0035] This utility model discloses an automatic riveting machine.
[0036] like Figures 1 to 4 As shown, the automatic riveting machine includes a worktable 10, on which a rectangular track 20 is mounted. Multiple carriers 30 are mounted on the rectangular track 20. The rectangular track 20 includes a first side 21, a second side 22, a third side 23, and a fourth side 24. The first side 21 connects to the second side 22, the second side 22 connects to the third side 23, the third side 23 connects to the fourth side 24, and the fourth side 24 connects to the first side 21. The first side 21 is used for loading materials and moving the carrier 30 carrying the workpiece to the second side 24. Side 22; the second side 22 is used to move the carrier 30 carrying the workpiece to the third side 23; the side of the third side 23 is equipped with a riveting actuator 40 and a unloading robot 50. The riveting actuator 40 is used to perform riveting operations on the workpiece on the carrier 30 of the third side 23, and the unloading robot 50 is used to clamp the workpiece after the riveting operation and unload it. The third side 23 is used to move the empty carrier 30 to the fourth side 24; the fourth side 24 is used to move the empty carrier 30 to the first side 21.
[0037] The aforementioned automatic riveting machine includes a worktable, on which a rectangular track is installed. Multiple carriers are set on the rectangular track. The rectangular track includes a first side, a second side, a third side, and a fourth side. The first side connects to the second side, the second side connects to the third side, the third side connects to the fourth side, and the fourth side connects to the first side. When the automatic riveting machine starts working, an empty carrier is placed on the first side. The workpiece to be riveted can be placed on the empty carrier on the first side manually or by a loading robot. Then, the carrier carrying the workpiece is moved to the second side by the drive mechanism, and then to the third side. The riveting actuator installed on the side of the third side can perform riveting operations on the workpiece on the carrier on the third side. Then, the carrier carrying the riveted workpiece is moved to the operating area of the unloading robot by the drive mechanism. The unloading robot picks up the workpiece after the riveting operation and unloads it. Then, the empty carrier on the third side is moved to the fourth side by the drive mechanism, and then the empty carrier on the fourth side is moved to the first side so that the manual or loading robot can continue to perform loading operations. In this way, the automatic riveting machine can automatically complete the three core processes of loading, riveting and unloading, effectively improving the automation level of the riveting process and meeting the user's needs for efficient production.
[0038] All carriers 30 are square. A first cylinder 211 is installed at the end of the first side 21, a second cylinder 221 is installed at the end of the second side 22, a third cylinder 231 is installed at the end of the third side 23, and a fourth cylinder 241 is installed at the end of the fourth side 24. The carriers 30 on the first side 21 are connected adjacent to each other. The first cylinder 211 is used to push the carrier 30 on the first carrier position 25 a preset length along the direction of the first side 21 when there is an empty carrier 30, thereby moving the carrier 30 carrying the workpiece on the first side 21 to the second carrier position 26. The second cylinder 221 is used to push the carrier 30 on the second carrier position 26 to the third carrier position 27 along the direction of the second side 22 when there is a carrier 30 on the second carrier position 26. The carriers 30 on the third side 23 are connected adjacent to each other. The third cylinder 231 is used to push the carrier 30 on the third carrier position 26 to the third carrier position 27 when there is an empty carrier 30 on the second carrier position 26. When there is a vehicle 30 on the third side 23, the vehicle 30 on the third vehicle position 27 is pushed a preset length along the direction of the third side 23, thereby pushing the empty vehicle 30 on the third side 23 to the fourth vehicle position 28; the vehicle 30 on the fourth side 24 is connected adjacently, and the fourth cylinder 241 is used to push the empty vehicle 30 on the fourth vehicle position 28 a preset length along the direction of the fourth side 24 when there is an empty vehicle 30 on the fourth vehicle position 28, thereby pushing the empty vehicle 30 on the fourth side 24 to the first vehicle position 25; the preset length is equal to the side length of the vehicle 30, the first vehicle position 25 is the vehicle position adjacent to the first side 21 and the fourth side 24, the second vehicle position 26 is the vehicle position adjacent to the first side 21 and the second side 22, the third vehicle position 27 is the vehicle position adjacent to the second side 22 and the third side 23, and the fourth vehicle position 28 is the vehicle position adjacent to the third side 23 and the fourth side 24.
[0039] It should be noted that, since the carriers 30 on the first side 21 are closely connected, when the first cylinder 211 pushes the carrier 30 on the first carrier position 25 a predetermined length along the direction of the first side 21, all the carriers 30 on the first side 21 move as a whole towards the second side 22 a predetermined length. This allows the carrier 30 carrying the workpiece on the first side 21 that is closest to the second side 22 to enter the second carrier position 26. The second cylinder 221 further pushes the carrier 30 carrying the workpiece from the second carrier position 26 to the third carrier position 27. Since the carriers 30 on the third side 23 are closely connected, when the third cylinder 231 pushes the carrier 30 on the third side 23... After the vehicle 30 on the third vehicle position 27 is pushed a preset length, all the vehicles 30 on the third side 23 move as a whole towards the fourth side 24 by a preset length, thereby allowing the empty vehicle 30 on the third side 23 that is closest to the fourth side 24 to enter the fourth vehicle position 28. Since the empty vehicles 30 on the fourth side 24 are connected in close proximity, when the fourth cylinder 241 pushes the vehicle 30 on the fourth vehicle position 28 along the direction of the fourth side 24 by a preset length, all the vehicles 30 on the fourth side 24 move as a whole towards the first side 21 by a preset length, thereby allowing the empty vehicle 30 on the fourth side 24 that is closest to the first side 21 to enter the first vehicle position 25. By controlling the action rhythm of the first cylinder 211, the second cylinder 221, the third cylinder 231 and the fourth cylinder 241, the carrier 30 can be cyclically moved from the first side 21 to the second side 22, from the second side 22 to the third side 23, from the third side 23 to the fourth side 24, and then from the fourth side 24 back to the first side 21. Combined with workpiece loading, workpiece riveting and workpiece unloading, the automation level of the riveting process can be significantly improved.
[0040] Each carrier 30 is provided with a first workpiece position 31 and a second workpiece position 32. The riveting execution mechanism 40 includes a first execution mechanism 41 and a second execution mechanism 42, which are spaced apart. The first execution mechanism 41 is used to perform riveting operation on the workpiece at the first workpiece position 31, and the second execution mechanism 42 is used to perform riveting operation on the workpiece at the second workpiece position 32.
[0041] By setting a first workpiece position 31 and a second workpiece position 32, each carrier 30 can carry two workpieces. When the carrier 30 moves on the third side 23, the first actuator 41 performs riveting operations only on the workpieces at the first workpiece position 31, and the second actuator 42 performs riveting operations only on the workpieces at the second workpiece position 32. Furthermore, when the carrier 30 moves on the third side 23, the first actuator 41 and the second actuator 42 perform riveting operations simultaneously. Through the cooperation of the first actuator 41 and the second actuator 42, the efficiency of the riveting operation can be improved.
[0042] The unloading robot 50 includes a first gripper 51 and a second gripper 52. The first gripper 51 is used to grip the workpiece on the first workpiece position 31, and the second gripper 52 is used to grip the workpiece on the second workpiece position 32. By setting the first gripper 51 and the second gripper 52, the unloading robot 50 can grip two workpieces on each carrier 30 at the same time, effectively improving the unloading efficiency.
[0043] Furthermore, the third side 23 is also equipped with a first pressing mechanism 60 that cooperates with the first actuator 41 and a second pressing mechanism 70 that cooperates with the second actuator 42. The first pressing mechanism 60 includes a fifth cylinder 61 and a first pressure plate 62 connected to the fifth cylinder 61. The second pressing mechanism 70 includes a sixth cylinder 71 and a second pressure plate 72 connected to the sixth cylinder 71. The first pressure plate 62 is used to press the workpiece on the first workpiece position 31 when the first actuator 41 performs riveting operation. The second pressure plate 72 is used to press the workpiece on the second workpiece position 32 when the second actuator 42 performs riveting operation. The first pressure plate 62 is provided with a first through hole that cooperates with the first actuator 41. The second pressure plate 72 is provided with a second through hole that cooperates with the second actuator 42.
[0044] By setting up the first pressing mechanism 60 and the second pressing mechanism 70, the workpiece on the carrier 30 is more stable and less prone to deviation during the riveting operation of the first actuator 41 and the second actuator 42, effectively improving the accuracy of the riveting operation. By setting up the first through hole and the second through hole, the riveting head of the first actuator 41 and the second actuator 42 can pass smoothly through the first through hole and the second through hole, respectively, thereby completing the riveting operation.
[0045] The workbench 10 is also equipped with a conveyor belt 80 that works in conjunction with the unloading robot 50. By setting up the conveyor belt 80, the riveted workpiece can be unloaded quickly.
[0046] The unloading robot 50 is installed between the conveyor belt 80 and the riveting actuator 40. Installing the unloading robot 50 between the conveyor belt 80 and the riveting actuator 40 makes the layout of the automatic riveting machine more rational. Preferably, the riveting actuator 40 is installed closer to the second side 22, and the conveyor belt 80 is installed closer to the fourth side 24, thereby effectively coordinating the working processes of the riveting actuator 40 and the conveyor belt 80.
[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0048] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
