Description

Technical Field

[0001] This application relates to the field of stacking and riveting technology, and in particular to a stacking and fixing device and production line. Background Technology

[0002] A component includes multiple stacked and fixed copper sheets. In related technologies, a copper strip is stamped by a stamping device to form individual copper sheets. A fixture is positioned below the stamping device, and multiple limiting blocks are set on the fixture. These limiting blocks enclose a limiting area, where the copper sheets fall and stack. Since the number of copper sheets in each component is fixed, and the stamping device stamps continuously, a separator plate needs to be placed on the stacked copper sheets after each preset number of copper sheets are stamped. After the strip is cut, adjacent copper sheets are welded together by a welding device. The separator plate cannot be welded to the copper sheets. After welding, the separator plate facilitates the separation of the copper sheets. The relative positions of the copper sheets can only be limited by the limiting blocks on the fixture, resulting in a relatively loose arrangement between the copper sheets. During the welding process, this can easily lead to incomplete soldering. Utility Model Content

[0003] This application aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes a stacking and fixing device that can stack and rivet punched copper sheets to make the copper sheets tightly connected, so as to prevent the copper sheets from loosening during welding.

[0004] This application also proposes a production line having the above-mentioned stacking and fixing device.

[0005] The stacking and fixing device according to a first aspect of the present application includes: a first moving mechanism, a first stamping mechanism, and a fixing mechanism.

[0006] The first moving mechanism includes a first moving drive and a first carrier. The first moving drive is connected to the first carrier and is used to drive the first carrier to move to the unloading position and the dropping position.

[0007] The first stamping mechanism includes a first stamping driver, a first punch, and a first base plate. The first base plate has a first punch hole. A first stamping area is formed between the first punch and the first base plate. The first stamping area corresponds to the area above the material dropping position. The first stamping area is used for passing material strip. The first stamping driver is connected to the first punch and is used to drive the first punch to pass through the first punch hole to punch the material strip to form a first sheet. Multiple first sheets fall into the first carrier located at the material dropping position. The first punch can also cooperate with the first carrier to rivet the first sheets in the first carrier.

[0008] A fixing mechanism used to secure the first stacked sheet.

[0009] The stacking and fixing device according to the first aspect embodiment of this application has at least the following advantages: the first stamping mechanism can continuously stamp the strip to form multiple first sheets. The first moving drive drives the first carrier to move to the dropping position, that is, below the first stamping area of ​​the first stamping mechanism, so that the punched-down first sheets can fall onto the first carrier. After the first punch of the first stamping mechanism, in conjunction with the first punch hole, forms a first sheet material that falls onto the first carrier, the first punch of the first stamping mechanism, in conjunction with the first punch hole, forms a second sheet material that falls above the previous sheet material. Subsequently, driven by the first stamping driver, the first punch continues to move downwards to apply downward pressure to the second sheet material, causing it to rivet together with the first sheet material. Thus, the first carrier can receive and stack multiple sheets material while simultaneously using multiple first punches to rivet multiple stacked sheets material together. After a predetermined number of sheets material are stacked, the first moving driver drives the first carrier to move to the unloading position to unload and fix the stacked sheets material. The fixing mechanism can then fix the stacked sheets material. In summary, the first stamping mechanism, in conjunction with the first carrier, can rivet multiple punched sheets together, ensuring a tight fit between them for easy fixing by the fixing mechanism, preventing unstable fixing. Furthermore, the first moving driver drives the first carrier to move between the unloading position and the dropping position for easy material handling, improving production efficiency.

The second stamping mechanism includes a second stamping driver, a second punch, and a second base plate. The second base plate has a second punch hole, and a second stamping area is formed between the second punch and the second base plate. The second stamping area is located above the moving path of the second carrier and is used for the material strip to pass through. The second stamping driver drives the second punch to pass through the second punch hole to punch the material strip with the first sheet to form a second sheet. The cross-section of the second punch is rotationally symmetrical with the cross-section of the first punch.

[0015] According to some embodiments of this application, it further includes a limiting mechanism, an upper template, and a lower template. The upper template is movable relative to the lower template. The first base plate is fixed to the lower template, and the first punch is movably disposed on the upper template.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0045] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 According to a first aspect embodiment of the present application, the stacking and fixing device includes: a first moving mechanism 100, a first stamping mechanism 200, and a fixing mechanism (not shown in the figure).

[0046] The first moving mechanism 100 includes a first moving driver 110 and a first carrier 120. The first moving driver 110 drives the first carrier 120 to move to the unloading position 140 and the dropping position.

[0047] 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 above the material drop position. The first stamping area 240 is used for passing the material strip 900. The first stamping driver 210 drives the first punch 220 to pass through the first punch hole 231 to punch the material strip 900 to form a first sheet 910. Multiple first sheets 910 fall into the first carrier 120 located at the material drop position. The first punch 220 can also cooperate with the first carrier 120 to rivet the first sheets 910 in the first carrier 120.

[0048] A fixing mechanism for fixing the first stacked sheet 910.

[0049] Understandably, the first stamping mechanism 200 can continuously stamp the strip 900 to form multiple first sheets 910. The first moving drive 110 drives the first carrier 120 to move to the dropping position, that is, below the first stamping area 240 of the first stamping mechanism 200, so that the stamped first sheets 910 can fall onto the first carrier 120. After the first punch 220 of the first stamping mechanism 200, in conjunction with the first punch 231, forms a first sheet 910 that falls onto the first carrier 120, the first punch 220 of the first stamping mechanism 200, in conjunction with the first punch 231, forms a second sheet 910 that falls above the previous sheet 910. After this, the first punch 220, driven by the first stamping driver 210, can continue to move downward to apply downward pressure to the second sheet 910, so that the second sheet 910 is riveted to the first sheet 910. Thus, the first carrier 120 can receive and stack multiple sheets 910 while simultaneously using multiple first punches 220 to rivet multiple stacked sheets 910. After the first sheets 910 are stacked to a predetermined number, the first moving driver 110 drives the first carrier 120 to move to the unloading position 140 to unload and fix the stacked sheets 910. The fixing mechanism can fix the stacked sheets 910. In summary, the first stamping mechanism 200, in conjunction with the first carrier 120, can stack and rivet multiple stamped first sheets 910, making the first sheets 910 tightly packed together, so that the fixing mechanism can fix them and avoid unstable fixing. Furthermore, the first moving drive 110 drives the first carrier 120 to move between the unloading position 140 and the dropping position, so as to facilitate material handling and improve production efficiency.

[0050] For example, a part includes 20 copper material sheets welded together. A first stamping mechanism 200 punches the copper material strip. A first carrier 120 moves to the dropping position. A first punch 220 cooperates with a first punch hole 231 on a first base plate 230 to punch the strip 900, so that the strip 900 forms a copper material sheet and falls onto the first carrier 120. Subsequently, the strip 900 is continuously conveyed forward. The first punch 220 punches the strip 900 multiple times and rivets adjacent copper material sheets together until after 20 punches, the first carrier 120 carries 20 copper material sheets that are stacked and riveted together. Next, the first moving drive mechanism drives the first carrier 120 to move to the unloading position 140. Multiple positioning blocks 121 are set on the first carrier 120. The multiple positioning blocks 121 surround to form a positioning area. The copper material sheet is located in the positioning area. The positioning blocks 121 limit the first material sheet 910. There are gaps between the positioning blocks 121. The fixing device can weld the stacked copper material sheets on the first carrier 120 through the gaps to fix the 20 stacked copper material sheets together. Since the 20 copper material sheets are riveted together, the connection is tight, the welding effect of the fixing device is good, and the risk of unstable connection of copper material sheets is reduced.

[0051] Reference Figure 1 , Figure 3 and Figure 4 According to some embodiments of this application, a third stamping mechanism 600 is also included. 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 has a third punch hole 631. A third stamping area 640 is formed between the third punch 620 and the third base plate 630. The third stamping area 640 is used for passing through the strip 900. The third stamping driver 610 drives the third punch 620 to pass through the third punch hole 631, so as to punch the strip 900 before forming the first sheet 910 in the strip 900 and form a riveting protrusion 911 on the strip 900.

[0052] Understandably, along the conveying direction of the strip 900, the strip 900 is conveyed from back to front. The third stamping mechanism 600 is located behind the first stamping mechanism 200. Before entering the first stamping area 240, the strip 900 will first pass through the third stamping area 640. The third stamping driver 610 drives the third punch 620 to descend. The third punch 620, in conjunction with the third punch hole 631, stamps the strip 900 passing through the third stamping area 640 to form a riveting protrusion 911 on the strip 900. Correspondingly, the riveting protrusion 911 will form The riveting groove 912 should be understood as corresponding to the forming position of the first sheet 910. When the first punch 220 cuts the strip 900, after cutting out the first sheet 910, the first punch 220 will form the riveting protrusion 911 on the first sheet 910. Then, the first punch 220 continues to press down, which can squeeze the first sheet 910 on the first carrier 120 so that the riveting protrusion 911 of the first sheet 910 can be inserted into the riveting groove 912 of the lower first sheet 910, so that the adjacent first sheets 910 can be riveted together. The third stamping mechanism 600 presets the riveting protrusion 911 on the strip 900 at the position corresponding to the first sheet 910, which is beneficial for the subsequent stacking and riveting of the first sheets 910.

[0053] According to some embodiments of this application, a punching mechanism (not shown in the figure) is also included, which is used to punch holes in the fixed first sheet 910, wherein the punching position covers the riveting protrusion 911.

[0054] It is understood that the parts produced by the stacking and riveting fixing device of this application have round holes. A punching mechanism can punch holes in the fixed first sheet 910 to form the aforementioned round holes. It should be noted that the riveting protrusion 911 is a temporary fixing means for stacking the first sheet 910. After the stacked first sheet 910 is welded and fixed, the riveting protrusion 911 needs to be removed. Therefore, the position of the riveting protrusion 911 corresponds to the punching position. After punching by the punching mechanism, the riveting protrusion 911 can be discharged along with the waste material from the round hole. It is understood that by utilizing the round hole feature inherent in the produced parts, the riveting protrusion 911 can be formed at the corresponding position of the round hole. After the stacked first sheet 910 is fixed, the punching mechanism punches out the round hole while simultaneously flushing away the riveting protrusion 911, reducing the steps required to remove the riveting protrusion 911.

[0055] Reference Figure 5 According to some embodiments of this application, the first punch 220 includes a first punching portion 221 and a first riveting portion 222 connected to each other. The first riveting portion 222 protrudes from the lower end face of the first punching portion 221. The first punching portion 221 corresponds to the outer contour of the first sheet 910, and the first riveting portion 222 corresponds to the riveting protrusion 911 on the first sheet 910.

[0056] Understandably, during the process of the first punch 220 engaging with the first punch hole 231, the first cutting part 221 is used to engage with the first punch hole 231 to form the outer contour of the first sheet 910, and the first riveting part 222 is used to insert into the riveting protrusion 911 and push the riveting protrusion 911 into the riveting groove 912 of the lower first sheet 910. Furthermore, the shape of the first riveting part 222 is adapted to the shape of the riveting protrusion 911, which can prevent the riveting protrusion 911 from deforming.

[0057] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6 According to some embodiments of this application, it also includes a second moving mechanism 300 and a second stamping mechanism 400;

[0058] The second moving mechanism 300 includes a second moving driver 310 and a second vehicle 320, wherein the second moving driver 310 drives the second vehicle 320.

[0059] The number of second stamping mechanisms 400 corresponds one-to-one with the number of first stamping mechanisms 200. The corresponding first stamping mechanisms 200 and second stamping mechanisms 400 are distributed along the conveying direction of the strip 900. The second stamping mechanism 400 includes a second stamping driver 410, a second punch 420, and a second base plate 430. The second base plate 430 has a second punch hole 431. A second stamping area 440 is formed between the second punch 420 and the second base plate 430. The second stamping area 440 is located above the moving path of the second carrier 320. The second stamping area 440 is used for passing the strip 900. The second stamping driver 410 drives the second punch 420 to pass through the second punch hole 431 to punch the strip 900 on which the first sheet 910 is formed to form the second sheet 920. The cross-section of the second punch 420 is rotationally symmetrical with the cross-section of the first punch 220.

[0060] It is understandable that a second stamping mechanism 400 is provided in front of each first stamping mechanism 200. The cooperation between the second stamping mechanism 400 and the second moving mechanism 300 is the same as the cooperation between the first stamping mechanism 200 and the first moving mechanism 100. This allows a second sheet 920 to be formed on the strip 900 that has already produced the first sheet 910. It should be noted that the first sheet 910 is roughly L-shaped. After the first sheet 910 is produced on the strip 900, there will be a lot of usable scrap area on the strip 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, in conjunction with the second punch hole 431, can utilize the scrap area on the strip 900 to punch and form a second sheet 920 that is rotationally symmetrical with the first sheet 910, thereby improving the utilization rate of the strip 900.

[0061] Specifically, the third stamping mechanism 600 has multiple riveting protrusions 911, some of which correspond to the punching positions of the second punch 420.

[0062] Specifically, refer to Figure 6 The second punch 420 includes a second punching portion 421 and a second riveting portion 422 connected to each other. The second riveting portion 422 protrudes from the lower end face of the second punching portion 421. The second punching portion 421 corresponds to the outer contour of the second sheet 920, and the second riveting portion 422 corresponds to the riveting protrusion 911 on the second sheet 920.

[0063] Understandably, during the process of the second punch 420 engaging with the second punch hole 431, the second cutting part 421 is used to engage with the second punch hole 431 to form the outer contour of the second sheet 920, and the second riveting part 422 is used to insert the riveting protrusion 911 and push the riveting protrusion 911 into the riveting groove 912 of the lower second sheet 920. Furthermore, the shape of the second riveting part 422 is adapted to the shape of the riveting protrusion 911, which can prevent the riveting protrusion 911 from deforming.

[0064] Reference Figure 7 and Figure 8 According to some embodiments of this application, it also includes a limiting mechanism 700, an upper template 810 and a lower template 820. The upper template 810 can be raised and lowered relative to the lower template 820. The first base plate 230 is fixed to the lower template 820. The first punch 220 is movably disposed on the upper template 810. The limiting mechanism 700 includes a plurality of limiting blocks 710. The limiting blocks 710 are disposed on the lower template 820 and can be raised and lowered relative to the first base plate 230. The limiting blocks 710 are at least partially located between the upper template 810 and the first base plate 230 and are located above the material strip 900. They can be pushed by the descending upper template 810 to press the material strip 900 onto the first base plate 230.

[0065] Understandably, when the upper mold plate 810 and the lower mold plate 820 are closed, the first stamping driver 210 is fixed to the upper mold plate 810 and can descend with the upper mold plate 810. The upper mold plate 810 pushes the limiting block 710 down, and the limiting block 710 presses down on the strip 900 to press the strip 900 onto the first base plate 230, thus limiting the strip 900. Subsequently, the first stamping driver 210 can drive the first punch 220 to rise and fall relative to the upper mold plate 810 to cooperate with the first punch 231 to punch the strip 900. When the upper mold plate 810 and the lower mold plate 820 are open, the upper mold plate 810 moves away from the limiting block 710, and the limiting block 710 resets, allowing the strip 900 to leave the first base plate 230, so that the strip 900 can be conveyed normally.

[0066] Reference Figure 7 and Figure 8According to some embodiments of this application, the limiting block 710 has a first limiting part 711 and a second limiting part 712 connected to each other. A limiting groove 713 is formed between the first limiting part 711 and the second limiting part 712. The limiting groove 713 is used for the material strip 900 to pass through. The first base plate 230 has a movable hole 232. The second limiting part 712 is vertically and vertically inserted through the movable hole 232. The first limiting part 711 is located between the upper template 810 and the first base plate 230. The size of the first limiting part 711 is longer than the diameter of the movable hole 232. The first limiting part 711 can be pushed by the upper template 810 to press the material strip 900 onto the first base plate 230.

[0067] Understandably, when the upper mold plate 810 and lower mold plate 820 open, the strip 900 passes through the limiting groove 713. The limiting groove 713 limits the width of the strip 900, ensuring that the conveying of the strip 900 is not skewed. At the same time, the second limiting part 712 protrudes from the movable hole 232, and the first limiting part 711 is located above the strip 900. When the upper mold plate 810 and lower mold plate 820 close, the upper mold plate 810 pushes the first limiting part 711, causing the second limiting part 712 to descend. The second limiting part 712 rises and falls relative to the movable hole 232 to allow the first limiting part 711 room to descend. The size of the first limiting part 711 is longer than the diameter of the movable hole 232, so the first limiting part 711 cannot pass through the movable hole 232. The first limiting part 711 presses the strip 900 onto the first base plate 230.

[0068] Specifically, at least two limit blocks 710 are provided, located on both sides of the width direction of the conveyor belt 900. The openings of the limit grooves 713 of the two limit blocks 710 are arranged opposite each other, so that the limit blocks 710 can only exert a clamping effect on the edge of the conveyor belt 900 in the width direction. Furthermore, multiple limit blocks 710 are provided, and the multiple limit blocks 710 are distributed along the conveying direction of the conveyor belt 900.
