[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0024] Please refer to Figures 1 to 5 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, which is a handling and riveting mechanism.

[0025] The movable module 50 enables the riveting module 60 and the feeding module 70 to move back and forth, realizing loading and riveting, improving loading and riveting efficiency, and saving time. At the same time, the workpiece attachment 12 is directly loaded onto the workpiece body 11 on the second feeding module 30, eliminating the need for loading the workpiece body 11, which can further improve riveting efficiency and speed.

[0026] This application provides a riveting and handling mechanism, including a first feeding module 20; a second feeding module 30 disposed beside the first feeding module 20; a moving module 50 disposed above the second feeding module 30; a riveting module 60 and a loading module 70 disposed on the moving module 50; and a drive module 40 disposed above the riveting module 60. The first feeding module 20 supplies a workpiece attachment 12; the second feeding module 30 supplies a workpiece body 11; the loading module 70 can load the workpiece attachment 12 onto the workpiece body 11; and the drive module 40 drives the riveting module 60 to rivet the workpiece attachment 12 and the workpiece body 11 together. The moving module 50 can be a lead screw servo module, which enables the riveting module 60 and the loading module 70 to move back and forth, realizing simultaneous material picking and riveting actions. Compared with a robotic arm, this mechanism is more efficient, has lower equipment costs, and significantly improves riveting efficiency and speed. The drive module 40 provides power to the riveting module 60, which rivets the workpiece body 11 and the workpiece attachment 12 together. The second feeding module 30 delivers the workpiece body 11, and the loading module 70 directly assembles the workpiece attachment 12 onto the workpiece body 11. This assembly method is more efficient and further improves riveting efficiency.

[0027] Preferably, the first feeding module 20 includes a fixed material tray 21, a gear 22 connected to the fixed material tray 21, and a rack 23 meshing with the gear 22; a first cylinder 24 connected to the rack 23; the first cylinder 24 can drive the fixed material tray 21 to rotate. The fixed material tray 21 is provided with a fixed material groove 25. The workpiece attachment 12 is placed in the fixed material groove 25 for positioning, and then picked up by the suction head on the feeding module 70, and then placed on the workpiece body 11 for assembly. There are two or more fixed material grooves 25. The first cylinder 24 drives the gear 22 to rotate through the rack 23, thereby causing the fixed material tray 21 to rotate as well. This design facilitates connection with other mechanisms and improves equipment adaptability.

[0028] Preferably, the second feeding module 30 includes a clip 31, a base plate 32, a cover plate 33, and a pusher plate 35; the cover plate 33 is disposed on the base plate 32, and a pusher channel is formed between the base plate 32 and the cover plate 33; the clip 31 is disposed at the inlet of the pusher channel; the cover plate 33 is provided with a first contour hole 34; the pusher plate 35 is provided with a second contour hole 36; the pusher plate 35 passes through the pusher channel; the pusher plate 35 pushes the workpiece 10 forward. The second feeding module 30 also includes a top material seat 37 and a fixed material seat 39; the top material seat 37 is disposed on the base plate 32 and can lift the workpiece 10 in the second contour hole 36; the fixed material seat 39 is disposed on the upper side of the top material seat 37; the fixed material seat 39 presses down on the top material seat 37. The root of the pusher plate 35 is mounted on the fifth slide block 350, which slides on the fifth slide rail 351 and is connected to the output end of the second cylinder 352. The magazine 31 has a feeding channel; a through hole is formed on its side. The magazine 31 contains a large number of workpiece bodies 11, which move downwards under gravity; the through hole facilitates observation of the material. The second cylinder 352 pushes the fourth slide block 422 to slide back and forth on the fourth slide rail 421, thereby allowing the pusher plate 35 to move back and forth in the feeding channel. When the second contour hole 36 moves to the discharge port of the magazine 31, the workpiece body 11 falls into the second contour hole 36, and then the pusher plate 35 pushes the workpiece body 11 forward in the pusher channel. When the workpiece body 11 moves to the riveting position, the third cylinder 38 drives the stationary seat 39 to press against the workpiece body 11, so that the workpiece body 11 will not loosen. At this time, the top seat 37 will drop a certain distance, and the workpiece body 11 will also drop synchronously. When the top seat 37 drops to the designed distance, the riveting table on the base plate 32 will support the riveting position, and then the riveting head 64 will rivet the workpiece body 11 and the workpiece attachment 12 together. After the riveting is completed, the top seat 37 will be lifted up by the action of the spring, lifting the finished product back to the second contour hole 36. Then the pusher plate 35 continues to push the workpiece 10 forward to the unloading position. The number of the first contour hole 34, the second contour hole 36, the top seat 37, and the stationary seat 39 are matched. This design makes the assembly and loading of workpiece 10 simpler, and the structure is simpler, resulting in lower equipment costs.

[0029] Preferably, the moving module 50 includes a mounting frame 51, a first lead screw servo assembly 52 disposed on the mounting frame 51, a first slide rail 53 disposed on the mounting frame 51, and a first slide block 54 slidably disposed on the first slide rail 53; the first lead screw servo assembly 52 drives the first slide block 54 to slide on the first slide rail 53; the riveting module 60 and the feeding module 70 are disposed on the first slide block 54. The first lead screw servo assembly 52 drives the first slide block 54 to slide on the first slide rail 53, so that the riveting module 60 and the feeding module 70 can move back and forth, realizing that the suction seat 73 of the feeding module 70 picks up the workpiece attachment 12; at the same time, the riveting module 60 rivets the workpiece body 11 and the workpiece attachment 12 together. This design has higher work efficiency and greatly saves the waiting time of the process.

[0030] Preferably, the riveting module 60 includes a second slide rail 61, a second slide block 62 slidably disposed on the second slide rail 61, a first spring rod 63 connected to the second slide block 62, and a riveting head 64 disposed on the second slide block 62; the second slide block 62 can compress the first spring rod 63. When the drive module 40 drives the riveting module 60 to operate, the first spring rod 63 can provide a certain buffering force to the second slide block 62, which can improve the downward pressure of the riveting head 64 and prevent damage to the product.

[0031] Preferably, the feeding module 70 includes a third slide rail 71, a third slide block 72 slidably disposed on the third slide rail 71, a suction seat 73 disposed on the third slide block 72, and a limiting rod disposed on the movement trajectory of the third slide block 72; the limiting rod can stop the third slide block 72. The limiting rod is used to control the movement range of the third slide block 72 to ensure movement accuracy. The fourth cylinder drives the third slide block 72 to slide up and down, and the suction seat 73 moves downward to pick up the workpiece attachment 12 on the fixed plate 21, and then loads the workpiece attachment 12 into the corresponding first contour hole 34, so that the workpiece body 11 and the workpiece attachment 12 are initially assembled together, which facilitates subsequent riveting.

[0032] Preferably, the drive module 40 includes a cam assembly 410 and a transmission assembly 420. The cam assembly 410 includes a cam 411 and a first servo motor 412, which drives the cam 411 to rotate. The transmission assembly 420 includes a fourth slide rail 421, a fourth slide block 422 slidably disposed on the fourth slide rail 421, and a force-receiving wheel 423 disposed on the fourth slide block 422. A second spring rod 424 is connected to the fourth slide block 422. The fourth slide block 422 can compress the second spring rod 424. The cam 411 can press against the force-receiving wheel 423. The first servo motor 412 can directly drive the cam 411 to rotate, or it can drive the cam 411 to rotate through a gearbox. When the cam 411 presses against the force-receiving wheel 423, the third slide block 72 moves downward, and then the third slide block 72 presses against the second slide block 62, causing the second slide block to move downward, ultimately enabling the riveting head 64 to rivet the workpiece body 11 and the workpiece attachment 12. The third spring rod provides cushioning and rebound force for the third slide 72, resulting in better riveting force and preventing impact damage to the equipment.

[0033] In summary, the key design feature of this invention is that its moving module 50 enables the riveting module 60 and the feeding module 70 to move back and forth. The driving module 40 drives the riveting module 60 to rivet the workpiece attachment 12 and the workpiece body 11 together, achieving material handling and riveting while saving process time. The feeding module 70 directly pre-assembles the workpiece attachment 12 onto the workpiece body 11, resulting in higher assembly efficiency, a more compact device, and improved production efficiency.
