[0026] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 According to the first aspect of the present application, the stack riveting device includes: a first moving mechanism 100 and a first punching mechanism 200.

[0027] The first moving mechanism 100 includes a first moving driver 110 and a first carrier 120 , and the first moving driver 110 drives and connects the first carrier 120 ; The first punching mechanism 200 includes a first punching driver 210, a first punch 220 and a first bottom plate 230. The first bottom plate 230 is provided with a first punch hole 231. A first punching area 240 is formed between the first punch 220 and the first bottom plate 230. The first punching area 240 corresponds to the upper side of the moving path of the first carrier 120. The first punching area 240 is used to pass the material strip 900. The first punching driver 210 is connected to the first punch 220 and is used to drive the first punch 220 to penetrate the first punch hole 231 to punch the material strip 900 to form a first sheet 910. Among them, 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 penetrates the first punch hole 231, it can also cooperate with the first carrier 120 to rivet the first material sheet 910 on the first carrier 120.

[0028] It is understandable that the multiple first punching mechanisms 200 can punch multiple strips 900 of different materials, so that the multiple strips 900 form first sheets 910 of different materials. The first moving driver 110 drives the first carrier 120 to move to the bottom of the first punching areas 240 of different first punching mechanisms 200 in sequence, so that the punched first sheets 910 can fall on the first carrier 120. After the first punch 220 of the previous first punching mechanism 200 cooperates with the first punching hole 231 to form a first sheet 910 that falls on the first carrier 120, the first punch 220 of the next first punching mechanism 200 cooperates with the first punching hole 231 to form a first sheet 910 that falls on the top of the previous first sheet 910. Afterwards, the first punch 220 can continue to move downward under the drive of the first punching driver 210 to give downward pressure to the next first sheet 910, so that the next first sheet 910 is riveted with the previous first sheet 910. Therefore, the first carrier 120 can receive and stack multiple first sheets 910 while cooperating with multiple first punches 220 to rivet the multiple stacked first sheets 910 together, which can facilitate the stacking and mutual fixation of the first sheets 910, so as to facilitate subsequent processing, reduce manual intervention, and improve production efficiency.

[0029] For example, a part is formed by overlapping a nickel-copper composite sheet, a copper material sheet and a copper-nickel composite sheet. The side with the nickel material needs to face outward. In one embodiment, three first stamping mechanisms 200 are provided, which respectively stamp three material strips 900. The three material strips 900 include a nickel-copper composite material strip 900a, a copper material strip 900b and a copper-nickel composite material strip 900c. The upper layer of the nickel-copper composite material strip 900a is nickel material and the lower layer is copper material. The upper layer of the copper-nickel composite material strip 900c is copper material and the lower layer is nickel material.

[0030] First, the first moving driver 110 drives the first carrier 120 to move to the bottom of the first stamping area 240 of the first stamping mechanism 200 corresponding to the copper-nickel composite material strip 900c. The copper-nickel composite material strip 900c passes through the first stamping area 240 of the first stamping mechanism 200. The first punch 220 cooperates with the first punch hole 231 on the first base plate 230 to punch the copper-nickel composite material strip 900c, so that the copper-nickel composite material strip 900c forms a copper-nickel composite sheet and falls onto the first carrier 120.

[0031] Next, the first mobile driver 110 drives the first carrier 120 to move to the bottom of the first stamping area 240 of the first stamping mechanism 200 corresponding to the copper material strip 900b. The copper material strip 900b passes through the first stamping area 240 of the first stamping mechanism 200. The first punch 220 cooperates with the first punch hole 231 on the first base plate 230 to punch the copper material strip 900b, so that the copper material strip 900b forms a copper material sheet and falls onto the first carrier 120. The copper material sheet will fall on top of the copper-nickel composite sheet. Driven by the first stamping driver 210, the first punch 220 rivets the copper material sheet and the copper-nickel composite sheet together.

[0032] Then, the first moving driver 110 drives the first carrier 120 to move to the bottom of the first punching area 240 of the first punching mechanism 200 corresponding to the nickel-copper composite material strip 900a, and the nickel-copper composite material strip 900a passes through the first punching area 240 of the first punching mechanism 200. The first punch 220 cooperates with the first punch hole 231 on the first bottom plate 230 to punch the nickel-copper composite material strip 900a, so that the nickel-copper composite material strip 900a forms a nickel-copper composite sheet and falls on the first carrier 120, and the nickel-copper composite sheet will fall on the copper material sheet. The first punch 220 is driven by the first punching driver 210, and the nickel-copper composite sheet is riveted together with the copper material sheet. Thus, the riveting of the first sheet 910 of three different materials is completed.

[0033] Subsequently, in order to facilitate unloading, the first moving driver 110 drives the first carrier 120 to move to the unloading position 140 away from the first punching mechanism 200, so that a human or a robot can manually or mechanically remove the first material sheets 910 stacked and riveted together in the first carrier 120. Then, the multi-layer first material sheets 910 can be further fixed to each other by welding or bonding.

[0034] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6According to some embodiments of the present application, the stack riveting device further includes a second moving mechanism 300 and a second punching mechanism 400; the second moving mechanism 300 includes a second moving driver 310 and a second carrier 320, and the second moving driver 310 drives and connects the second carrier 320; the number of the second punching mechanisms 400 corresponds to the number of the first punching mechanisms 200, and the corresponding first punching mechanisms 200 and second punching mechanisms 400 are distributed along the conveying direction of the material belt 900; the second punching mechanism 400 includes 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 a second punching area 440 is formed between the second punch 420 and the second bottom plate 430. The second punching area 440 corresponds to the upper part of the moving path of the second carrier 320. The second punching area 440 is used to pass the material strip 900. The second punching driver 410 drives the second punch 420 to drive the second punch 420 to penetrate into the second punching hole 431 to punch out the material strip 900 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 with the cross section of the first punch 220.

[0035] 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 a second punching mechanism 400 is arranged in front of each first punching mechanism 200. 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, and the second material sheet 920 can be formed again 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 roughly L-shaped. After the first material sheet 910 is punched out on the material belt 900, there will be more usable waste areas on the material belt 900. By setting the cross-section of the second punch 420 to be rotationally symmetrical with the cross-section of the first punch 220, the second punch 420 cooperates with the second punching hole 431 to utilize the waste area on the material belt 900 to punch out a second material sheet 920 that is rotationally symmetrical with the first material sheet 910, thereby improving the utilization rate of the material belt 900.

[0036] Reference Figure 3 and Figure 4According to some embodiments of the present application, the stack riveting device also includes a third stamping mechanism 600, the number of the third stamping mechanisms 600 corresponds to the number of the first stamping mechanisms 200, and the corresponding third stamping mechanisms 600 and the first stamping mechanisms 200 are distributed along the conveying direction of the material strip 900; the third stamping mechanism 600 includes a third stamping driver 610, a third punch 620 and a third base plate 630, the third base plate 630 is provided with a third punching hole 631, and a third stamping area 640 is formed between the third punch 620 and the third base plate 630, and the third stamping area 640 is used to pass the material strip 900, and the third stamping driver 610 drives the third punch 620 to drive the third punch 620 to penetrate the third punching hole 631, so as to punch the material strip 900 before forming the first sheet 910 on the material strip 900 to form a riveting protrusion 911 on the material strip 900.

[0037] It can be understood that a third stamping mechanism 600 is arranged behind each first stamping mechanism 200. Before the material strip 900 enters the first stamping area 240, the material strip 900 will first pass through the third stamping area 640. The third stamping driver 610 drives the third punch 620 of the rod to descend. The third punch 620 cooperates with the third punch hole 631 to stamp the material strip 900 passing through the third stamping area 640 to form a riveting protrusion 911 on the material strip 900. Correspondingly, the riveting protrusion 911 will form a riveting groove 912. It should be understood that It is understood that the position of the rivet protrusion 911 corresponds to the forming position of the first material piece 910. When the first punch 220 punches the material strip 900, after the first punch 220 punches out the first material piece 910, a rivet protrusion 911 will be formed on the first material piece 910. Then, the first punch 220 continues to press down, which can squeeze the first material piece 910 on the first carrier 120, so that the rivet protrusion 911 of the first material piece 910 is inserted into the rivet groove 912 of the first material piece 910 below, so that adjacent first material pieces 910 are riveted together. The rivet protrusion 911 is preset at the position corresponding to the first material piece 910 on the material strip 900 by the third punching mechanism 600, which is convenient for the subsequent stacking of the first material piece 910.

[0038] Specifically, the third punching mechanism 600 is formed with a plurality of riveting protrusions 911 , and some of the riveting protrusions 911 correspond to the punching positions of the second punch 420 .

[0039] In other embodiments, the punched first sheet 910 can also be directly punched out and form the rivet protrusion 911 simultaneously by the first punch 220 , so that the first sheet 910 is directly riveted with the first sheet 910 below during being pushed by the first punch 220 .

[0040] According to some embodiments of the present application, a punching mechanism is further included, and the punching mechanism is used to punch holes in the first sheet 910 after overlapping and riveting, wherein the punching position covers the riveting protrusion 911.

[0041] It is understandable that the parts produced by the stack riveting device of the present application have round holes, and the first sheet 910 after stack riveting can be punched by the punching mechanism to form the above-mentioned round holes. It should be noted that the riveting protrusion 911 is a temporary fixing means for stacking the first sheet 910. After the first sheet 910 of the stack riveting is subsequently welded and fixed, 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 hole, the riveting protrusion 911 can be discharged with the round hole waste. It can be seen that the round hole feature of the produced parts itself can be used to form the riveting protrusion 911 at the corresponding position of the round hole. After the first sheet 910 of the stack riveting is fixed, the punching mechanism punches out the round hole while punching the riveting protrusion 911 away, reducing the steps of removing the riveting protrusion 911.

[0042] Reference Figure 5 According to some embodiments of the present application, the first punch 220 includes a first punching portion 221 and a first riveted portion 222 connected to each other, the first riveted portion 222 protrudes from the lower end surface of the first punching portion 221, the first punching portion 221 corresponds to the outer contour of the first sheet 910, and the first riveted portion 222 corresponds to the riveting protrusion 911 on the first sheet 910.

[0043] It can be understood that, in the process of the first punch 220 cooperating with the first punch hole 231, the first punching portion 221 is used to cooperate with the first punch hole 231 to form the outer contour of the first sheet 910, and the first riveted portion 222 is used to insert the riveted protrusion 911, and push the riveted protrusion 911 into the riveting groove 912 of the first sheet 910 below, and the shape of the first riveted portion 222 is adapted to the shape of the riveted protrusion 911, which can prevent the riveted protrusion 911 from deforming.

[0044] Reference Figure 6 According to some embodiments of the present application, the second punch 420 includes a second punching portion 421 and a second riveted portion 422 connected to each other, the second riveted portion 422 protrudes from the lower end surface of the second punching portion 421, the second punching portion 421 corresponds to the outer contour of the second sheet 920, and the second riveted portion 422 corresponds to the riveting protrusion 911 on the second sheet 920.

[0045] It can be understood that, in the process of the second punch 420 cooperating with the second punch hole 431, the second punching portion 421 is used to cooperate with the second punch hole 431 to form the outer contour of the second sheet 920, and the second riveted portion 422 is used to insert the riveting protrusion 911, and push the riveting protrusion 911 into the riveting groove 912 of the second sheet 920 below, and the shape of the second riveted portion 422 is adapted to the shape of the riveting protrusion 911, which can prevent the riveting protrusion 911 from deforming.

[0046] Reference Figure 1 and Figure 7 According to some embodiments of the present application, at least two first punching drivers 210 are distributed along the height direction.

[0047] It can be understood that the first punching driver 210 includes a cylinder and a plunger, and the cylinder pushes the first punch 220 up and down through the translation of the plunger. By distributing at least two first punching drivers 210 along the height direction, it is helpful to save space.

[0048] Reference Figure 1 According to some embodiments of the present application, at least two second punching drivers 410 are distributed along the height direction.

[0049] It can be understood that the second punching driver 410 includes a cylinder and a plunger, and the cylinder pushes the second punch 420 up and down through the translation of the plunger. By distributing at least two second punching drivers 410 in the height direction, it is helpful to save space.

[0051] It is understandable that when the upper template 810 and the lower template 820 are closed, the first punching driver 210 is fixed to the upper template 810 and can follow the upper template 810 to descend, the upper template 810 pushes the limit block 710 to descend, and the limit block 710 presses the material strip 900 downward to press the material strip 900 on the first bottom plate 230, which limits the material strip 900, and then the first punching driver 210 can drive the first punch 220 to rise and fall relative to the upper template 810 to cooperate with the first punching hole 231 to punch and cut the material strip 900. When the upper template 810 and the lower template 820 are opened, the upper template 810 is away from the limit block 710, and the limit block 710 is reset to allow the material strip 900 to leave the first bottom plate 230, so that the material strip 900 can be normally transported.

[0053] It is understandable that when the upper template 810 and the lower template 820 are opened, the material strip 900 passes through the limiting groove 713, and the limiting groove 713 limits the width direction of the material strip 900, ensuring that the conveying of the material strip 900 will not be deflected. At the same time, the second limiting portion 712 partially protrudes from the movable hole 232, and the first limiting portion 711 is located above the material strip 900. When the upper template 810 and the lower template 820 are closed, the upper template 810 pushes the first limiting portion 711 to drive the second limiting portion 712 to descend, and the second limiting portion 712 rises and falls relative to the movable hole 232 to allow the first limiting portion 711 to have space to descend. The size of the first limiting portion 711 is longer than the aperture of the movable hole 232, and the first limiting portion 711 cannot penetrate the movable hole 232. The first limiting portion 711 presses the material strip 900 on the first bottom plate 230.

[0054] Specifically, at least two limit blocks 710 are provided, and are located on both sides of the width direction of the material belt 900. The notches of the limit slots 713 of the two limit blocks 710 are arranged opposite to each other, so that the limit blocks 710 can only play a pressing role on the edge in the width direction of the material belt 900. Further, there are multiple limit blocks 710, and the multiple limit blocks 710 are distributed along the conveying direction of the material belt 900.

[0055] Specifically, the second base plate 430 and the third base plate 630 are fixed to the lower template 820, the second punch driver 410 and the third punch driver 610 are fixed to the upper template 810, the second punch 420 and the third punch 620 are movably arranged on the upper template 810, and the second base plate 430 and the third base plate 630 are also correspondingly provided with liftable limit blocks 710.

[0056] Reference Figure 7 and Figure 8 According to some embodiments of the present application, the limiting mechanism 700 further includes an elastic member 720 , one end of the elastic member 720 is connected to the lower end of the second limiting portion 712 , and the other end is fixedly connected to the lower template 820 .

[0057] It is understandable that during the opening process of the upper template 810 and the lower template 820, the elastic member 720 will give the second limiting portion 712 an upward elastic force so that the second limiting portion 712 can drive the first limiting portion 711 to rise, thereby realizing automatic resetting of the limiting block 710. At the same time, the second limiting portion 712 will push the material strip 900 away from the first base plate 230.

[0058] Reference Figure 2 According to some embodiments of the present application, the first moving mechanism 100 further includes a lifting driver 130 , and the lifting driver 130 is driven and connected to the first carrier 120 to drive the first carrier 120 to rise and fall.

[0059] It can be understood that the lifting drive 130 is arranged at the driving end of the first movable drive 110, and the first carrier 120 is arranged at the driving end of the lifting drive 130. The first movable drive 110 can drive the lifting drive 130 and the first carrier 120 to translate together. After the first carrier 120 moves to the first stamping area 240, the lifting drive 130 can drive the first carrier 120 to approach the first punching hole 231 so that the first sheet 910 can fall onto the first carrier 120 more accurately. Furthermore, the first carrier 120 can enter the first punching hole 231, and the first punching hole 231 can simultaneously limit the first carrier 120, thereby improving the stability of the first carrier 120 cooperating with the first punch 220 to perform riveting on the first sheet 910.

[0060] Specifically, refer to Figure 2 A plurality of positioning blocks 121 are disposed on the first carrier 120 , and the plurality of positioning blocks 121 enclose a positioning area. The first material piece 910 is located in the positioning area, and the positioning blocks 121 limit the first material piece 910 .

[0061] According to the stack riveting method of the second aspect of the present application, a plurality of sheets are stack riveted by the stack riveting device of the first aspect of the present application.

[0062] The stack riveting method according to the second aspect of the present application has at least the following beneficial effects: including all the beneficial effects of the stack riveting device of the first aspect.

[0063] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
