[0043] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 5 , the riveting device according to the first aspect embodiment of the present application comprises a first moving mechanism 100 and a first stamping mechanism 200.

[0044] The first moving mechanism 100 comprises a first moving driver 110 and a first carrier 120, and the first moving driver 110 drives the first carrier 120;

[0045] The first stamping mechanism 200 includes a first stamping driver 210, a first punch 220, and a first base plate 230. The first base plate 230 has a first punch hole 231. A first stamping area 240 is formed between the first punch 220 and the first base plate 230. The first stamping area 240 is located above the moving path of the first carrier 120. The first stamping area 240 is used for passing the strip 900. The first stamping driver 210 drives the first punch 220 to pass through the first punch hole 231 to punch the strip 900 to form a first sheet 910.

[0046] The first stamping mechanism 200 is provided with at least two, and the first stamping areas 240 of the multiple stamping mechanisms are distributed along the moving path of the first carrier 120. After the first punch 220 passes through the first punch hole 231, it can also cooperate with the first carrier 120 to rivet the first sheet 910 on the first carrier 120.

[0047] Understandably, multiple first stamping mechanisms 200 can stamp multiple strips 900 of different materials to form first sheet 910 of different materials. The first moving drive 110 drives the first carrier 120 to move sequentially below the first stamping areas 240 of different first stamping mechanisms 200, so that the stamped first sheet 910 can land on the first carrier 120. After the first punch 220 of the previous first stamping mechanism 200, in conjunction with the first punch 231, forms the first sheet 910 that lands on the first carrier 120, the first punch 220 of the next first stamping mechanism 200, in conjunction with the first punch 231, forms the first sheet 910 that lands above the previous first sheet 910. Subsequently, the first punch 220 can continue to move downward under the drive of the first punch driver 210 to apply downward pressure to the next first sheet 910, so that the next first sheet 910 is riveted to the previous first sheet 910. Thus, the first carrier 120 can receive and stack multiple first sheets 910 while cooperating with multiple first punches 220 to rivet multiple stacked first sheets 910 together. This facilitates the stacking and mutual fixation of the first sheets 910, which is convenient for subsequent processing, reduces manual intervention, and improves production efficiency.

[0048] For example, a part is made of nickel-copper composite sheet, copper material sheet and copper-nickel composite sheet stacked together, with the side containing nickel material facing outward. In one embodiment, the first stamping mechanism 200 is provided with three, which stamp the three types of strips 900 respectively. The three types of strips 900 include nickel-copper composite strip 900a, copper material strip 900b and copper-nickel composite strip 900c. The upper layer of nickel-copper composite strip 900a is nickel material and the lower layer is copper material, and the upper layer of copper-nickel composite strip 900c is copper material and the lower layer is nickel material.

[0049] Firstly, the first moving driver 110 drives the first carrier 120 to move to the position below the first punching area 240 of the first punching mechanism 200 corresponding to the copper-nickel composite material strip 900c, the copper-nickel composite material strip 900c passes through the first punching area 240 of the first punching mechanism 200, and the first punch 220 punches the copper-nickel composite material strip 900c through the first punching hole 231 on the first bottom plate 230, so that the copper-nickel composite material strip 900c forms a copper-nickel composite material sheet and falls on the first carrier 120.

[0050] Then, the first moving driver 110 drives the first carrier 120 to move to the position below the first punching area 240 of the first punching mechanism 200 corresponding to the copper material strip 900b, the copper material strip 900b passes through the first punching area 240 of the first punching mechanism 200, and the first punch 220 punches the copper material strip 900b through the first punching hole 231 on the first bottom plate 230, so that the copper material strip 900b forms a copper material sheet and falls on the first carrier 120, and the copper material sheet will fall on the copper-nickel composite material sheet, and the first punch 220 is driven by the first punching driver 210, so that the copper material sheet and the copper-nickel composite material sheet are riveted together.

[0051] Then, the first moving driver 110 drives the first carrier 120 to move to the position below the first punching area 240 of the first punching mechanism 200 corresponding to the copper-nickel composite material strip 900c, the copper-nickel composite material strip 900c passes through the first punching area 240 of the first punching mechanism 200, and the first punch 220 punches the copper-nickel composite material strip 900c through the first punching hole 231 on the first bottom plate 230, so that the copper-nickel composite material strip 900c forms a copper-nickel composite material sheet and falls on the first carrier 120.

[0052] Subsequently, in order to facilitate discharging, the first moving driver 110 drives the first carrier 120 to move to the discharging position 140 away from the first punching mechanism 200, so as to facilitate the manual or mechanical hand to take away the first sheet 910 stacked and riveted together in the first carrier 120. Then, the multiple first sheets 910 can be further fixed to each other by welding or bonding.

[0053] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 6According to some embodiments of the present application, the riveting device further comprises a second moving mechanism 300 and a second punching mechanism 400; the second moving mechanism 300 comprises a second moving driver 310 and a second carrier 320, the second moving driver 310 is drivingly connected to the second carrier 320; the number of the second punching mechanism 400 corresponds to the number of the first punching mechanism 200, and the corresponding first punching mechanism 200 and the second punching mechanism 400 are distributed along the conveying direction of the material belt 900; the second punching mechanism 400 comprises a second punching driver 410, a second punch 420 and a second bottom plate 430, the second bottom plate 430 is provided with a second punching hole 431, and the second punch 420 and the second bottom plate 430 form a second punching area 440 therebetween, the second punching area 440 is above the moving path of the second carrier 320, the second punching area 440 is used for passing the material belt 900, the second punching driver 410 is drivingly connected to the second punch 420, and is used for driving the second punch 420 to penetrate into the second punching hole 431 to punch and cut the material belt 900 provided with the first material sheet 910 to form a second material sheet 920; wherein the cross section of the second punch 420 is rotationally symmetrical to the cross section of the first punch 220.

[0054] It can be understood that along the conveying direction of the material belt 900, the material belt 900 is conveyed from back to front, and each first punching mechanism 200 is provided with a second punching mechanism 400 in front of the first punching mechanism 200, and the cooperation mode of the second punching mechanism 400 and the second moving mechanism 300 is the same as the cooperation mode of the first punching mechanism 200 and the first moving mechanism 100, which can form the second material sheet 920 on the material belt 900 from which the first material sheet 910 has been punched out. It should be noted that the first material sheet 910 is substantially L-shaped, and after the first material sheet 910 is punched out on the material belt 900, there will be a lot of available waste area on the material belt 900, and by setting the cross section of the second punch 420 to be rotationally symmetrical to the cross section of the first punch 220, the second punch 420 cooperating with the second punching hole 431 can utilize the waste area on the material belt 900 to punch and cut the second material sheet 920 which is rotationally symmetrical to the first material sheet 910, thereby improving the utilization rate of the material belt 900.

[0055] Referring to Figure 3 and Figure 4According to some embodiments of the present application, the riveting device further comprises a third punching mechanism 600, the number of the third punching mechanism 600 corresponds to the number of the first punching mechanism 200, and the corresponding third punching mechanism 600 and the first punching mechanism 200 are distributed along the conveying direction of the material belt 900; the third punching mechanism 600 comprises a third punching driver 610, a third punch 620, and a third bottom plate 630, the third bottom plate 630 is provided with a third punch hole 631, and the third punch 620 and the third bottom plate 630 form a third punching area 640, the third punching area 640 is used for passing through the material belt 900, the third punch 620 is driven by the third punching driver 610, and the third punch 620 is driven to penetrate into the third punch hole 631 to form a riveting protrusion 911 on the material belt 900 before the material belt 900 is punched to form the first material piece 910.

[0056] It can be understood that a third punching mechanism 600 is arranged behind each first punching mechanism 200, and the material belt 900 will pass through the third punching area 640 before entering the first punching area 240, the third punch 620 is driven by the third punching driver 610 to descend, and the third punch 620 cooperates with the third punch hole 631 to punch the material belt 900 passing through the third punching area 640 to form a riveting protrusion 911 on the material belt 900, and correspondingly, the riveting protrusion 911 forms a riveting groove 912, it should be understood that the position of the riveting protrusion 911 corresponds to the forming position of the first material piece 910, when the first punch 220 punches the material belt 900, the first material piece 910 will form the riveting protrusion 911 after the first punch 220 punches out the first material piece 910, then the first punch 220 continues to press down to extrude the first material piece 910 on the first carrier 120, so that the riveting protrusion 911 of the first material piece 910 is inserted into the riveting groove 912 of the first material piece 910 below, so that the adjacent first material pieces 910 are riveted. By pre-setting the riveting protrusion 911 on the material belt 900 corresponding to the position of the first material piece 910 through the third punching mechanism 600, it is beneficial to the subsequent riveting of the first material piece 910.

[0057] Specifically, the third punching mechanism 600 forms a plurality of riveting protrusions 911, and part of the riveting protrusions 911 correspond to the punching position of the second punch 420.

[0058] In other embodiments, the punched first material piece 910 can also directly realize the simultaneous punching of the outer shape and the formation of the riveting protrusion 911 by the first punch 220, so that the first material piece 910 is directly riveted with the first material piece 910 below in the process of being pushed by the first punch 220.

[0059] According to some embodiments of the present application, a punching mechanism is further included, the punching mechanism is used for punching the first material piece 910 after riveting, and the punching position covers the riveting protrusion 911.

[0060] It can be understood that the part produced by the riveting device has a circular hole, and the first sheet 910 after riveting can be punched by the punching mechanism to form the circular hole. It should be noted that the riveting protrusion 911 is a temporary fixing means for stacking the first sheet 910, and after the riveted first sheet 910 is fixed by welding, the riveting protrusion 911 needs to be removed. Thus, the position of the riveting protrusion 911 corresponds to the punching position, and after the punching mechanism punches, the riveting protrusion 911 can be removed along with the circular hole waste. It can be seen that the riveting protrusion 911 can be formed at the corresponding position of the circular hole by using the circular hole feature of the produced part itself, and after the riveted first sheet 910 is fixed, the riveting protrusion 911 is punched out at the same time as the circular hole, reducing the step of removing the riveting protrusion 911.
