Description

Technical Field

[0001] The present invention relates to the technical field of stamping of new energy battery casings, and particularly to a battery casing stamping device. Background Art

[0002] With the transformation of the global energy structure and the development trend of the automotive industry towards cleaner and more intelligent, new energy vehicle technology is undergoing breakthrough innovations. As the core power source of new energy vehicles, the power battery pack adopts an innovative technical architecture - by integrating advanced power electronics technology, intelligent thermal management systems, and innovative structural designs, significant improvements in energy density and safety performance have been achieved. In the battery pack manufacturing process, the high-precision stamping-formed aluminum alloy casing has become the mainstream choice in the industry due to its excellent lightweight characteristics and structural strength.

[0003] However, there are still technical bottlenecks that need to be overcome in the practical application of the current mainstream progressive die stamping process. Notably, in the high-speed continuous blanking and stretching processes, intense friction between the die and the sheet metal generates micron-sized metal debris. These debris are likely to remain on the surface of the die cavity during the dynamic forming process, resulting in relative movement between the debris and the surface of the formed part during the ejection process during subsequent demolding, forming linear scratches, which will reduce the fatigue life of the casing structure. This phenomenon has become a problem that needs to be solved urgently by those in this field. Summary of the Invention

Specific embodiments

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figures 1-9, the present invention provides a technical solution: a battery case stamping device, including a stamping machine tool 1, a stamping mechanism is arranged on the stamping machine tool 1, a conveying mechanism is arranged on the left side of the stamping machine tool 1, and a control console 2 is arranged on the right side of the stamping machine tool 1;

[0038] The stamping mechanism includes an upper die assembly and a lower die assembly. The upper die assembly includes an upper stamping table 9, and the upper stamping table 9 is arranged above the stamping machine tool 1 through hydraulic drive. An upper punching die 24 is fixed to the bottom of the upper stamping table 9.

[0039] The lower die assembly includes a lower stamping table 6. Four groups of support rods 25 are fixed to the top of the lower stamping table 6. The four groups of support rods 25 are evenly distributed around the lower stamping table 6. A limiting plate 26 is fixed to the top of the four groups of support rods 25. A through groove 30 is formed in the middle of the limiting plate 26;

[0040] A lower punching die 34 is fixed to the middle of the lower stamping table 6. Two groups of placement tubes 37 are fixed inside the lower stamping table 6. Two groups of elastic telescopic rods 35 are arranged in the middle of the lower punching die 34. Each group of elastic telescopic rods 35 passes through the lower punching die 34 and is arranged inside the placement tube 37. The bottom of each group of elastic telescopic rods 35 is fixedly connected to the placement tube 37. A spring 36 is sleeved outside the elastic telescopic rod 35. The spring 36 is arranged inside the placement tube 37 and the lower punching die 34. A punching plate 29 is fixed to the top of each group of elastic telescopic rods 35. The punching plate 29 has a clearance fit with the lower punching die 34. The limiting plate 26 is located inside the through groove 30. The initial heights of the punching plate 29 and the limiting plate 26 are the same.

[0041] Two groups of first cylinders 27 are fixed to the limiting plate 26. The two groups of first cylinders 27 are respectively arranged on the front and back sides of the through groove 30. A positioning plate 28 is fixed to each group of first cylinders 27. The two groups of positioning plates 28 are used to position the sheet to be stamped.

[0042] It should be added that the height of the upper punching die 24 is greater than the sum of the height of the lower punching die 34 and the height of the first cylinder 27 to prevent the upper stamping table 9 from squeezing the first cylinder 27 during stamping.

[0043] When the battery housing needs to be stamped, the sheet to be stamped is placed on the bearing surface of the limit plate 26. Synchronously control the two groups of first cylinders 27 to extend, drive the positioning plate 28 to move against the edge of the sheet and form abutting positioning. Then start the stamping machine tool 1, and through hydraulic drive, control the upper stamping table 9 to drive the upper punch die 24 to stamp the sheet downward in the vertical direction. When the upper punch die 24 contacts the sheet during downward stamping, control the positioning plate 28 to move away from the sheet. The sheet contacts the limit plate 26 under the action of the upper punch die 24, and then compresses the elastic telescopic rod 35 to the bottom of the lower punch die 34, and the spring 36 enters the placement tube 37 as it is compressed. The sheet is stamped into the shape of a battery housing through the cavity matching of the upper punch die 24 and the lower punch die 34. After a stamping operation is completed, the upper punch die 24 resets and lifts. After the spring 36 and the elastic telescopic rod 35 are under contact pressure restraint, they elastically reset, and the stamped battery housing is lifted to the surface of the limit plate 26 through the stamping plate 29. Then control the first cylinder 27 to extend again to fix the formed battery housing through the positioning plate 28.

[0044] The transport mechanism includes a moving component and a cleaning component. The moving mechanism includes a first bearing platform 4 and a second bearing platform 7. The second bearing platform 7 is arranged on the right side of the first bearing platform 4. A conveyor belt 5 is arranged on the first bearing platform 4, and the formed battery housing is transported to other production lines through the conveyor belt 5. A placement platform 8 is driven and connected to the second bearing platform 7 through a cylinder. An installation column 10 is arranged on the front side of the first bearing platform 4. A mounting plate 12 is fixed on the side of the installation column 10 close to the first bearing platform 4. A first screw drive is arranged on the mounting plate 12. A connecting plate 13 is fixed to the bottom of the mounting plate 12. The first screw drive is connected to the connecting plate 13. A bearing rod 14 is fixed to the bottom of the connecting plate 13. A second screw drive is arranged inside the bearing rod 14. A moving block 15 is threadedly connected below the second screw drive. The cleaning component is arranged on the moving block 15. A first camera 18 and a second camera 19 are fixed on the side of the moving block 15 close to the stamping machine tool 1. The first camera 18 is located above the moving block 15, and the second camera 19 is located below the moving block 15;

[0045] A storage tank 11 is fixed to the top of the installation column 10, and a lubricating fluid is arranged inside the storage tank 11.

[0046] The cleaning component includes two groups of first bearing plates 16 and a robotic arm 3. The two groups of first bearing plates 16 are respectively located on the left and right sides of the moving block 15. Two second cylinders 17 are fixed on each group of first bearing plates 16. A connecting platform one 22 is fixed to the output end of the second cylinder 17. A central cavity 41 is opened in the middle of the connecting platform one 22. A number of first nozzles 40 are connected to the upper part of the connecting platform one 22. The number of first nozzles 40 are all connected to the central cavity 41. A central tube 38 is connected between the storage tank 11 and the central cavity 41, and a first pump body 42 is connected to the central tube 38;

[0047] On one side of the connecting platform 22 close to the stamping machine tool 1, two groups of connecting frames 20 are fixed. At the end of the connecting frame 20, an electromagnetic chuck 21 is fixed. Above the electromagnetic chuck 21, a temperature sensor 23 is arranged. The temperature sensor 23 is fixedly connected to the connecting frame 20. The formed battery housing can be adsorbed by the electromagnetic chuck 21.

[0048] A first motor 39 is fixed on the moving block 15. The output end of the first motor 39 is fixedly connected to the bearing plate 16.

[0049] The robotic arm 3, the temperature sensor 23, the first camera 18 and the second camera 19 are all electrically connected to the control console 2.

[0050] It should be noted that the first lead screw drive and the second lead screw drive are both prior arts and will not be elaborated here.

[0051] On one side of the robotic arm 3 close to the stamping machine tool 1, a second bearing plate 31 is fixed. On one side of the second bearing plate 31, two groups of third air cylinders 32 are fixed. At the output ends of the two groups of third air cylinders 32, a second connecting platform 43 is fixed. On one side of the second connecting platform 43 close to the stamping machine tool 1, a number of brushes 33 and a number of second nozzles 44 are fixed. The second nozzles 44 are arranged between the brushes 33. A number of transmission pipes 45 are fixedly connected between the second connecting platform 43 and the second bearing plate 31. The transmission pipes 45 are connected to a gas source (not shown in the figure) through pipelines.

[0052] The transmission pipe 45 is made of an elastic material.

[0053] When it is necessary to move and clean the formed battery housing, the synchronous control is started to drive the moving block 15 to move close to the formed battery housing, extend the electromagnetic chuck 21 on the right side of the moving block 15 into the cavity of the formed battery housing, start the electromagnetic chuck 21 to adsorb the battery housing. After the battery housing is adsorbed, control the moving block 15 to move away from the stamping machine tool 1, move the formed battery housing to the placing table 8. While the electromagnetic chuck 21 on the right side adsorbs the formed battery housing, judge whether there are scratches inside the cavity of the formed battery housing to ensure the stamping quality.

[0054] Specifically, while the electromagnetic chuck 21 on the right side of the moving block 15 enters the cavity of the battery housing, the temperature sensor 23 monitors the temperature inside the cavity of the battery housing and transmits it to the control console 2. Set the conventional temperature range value as a in the control console 2. When the temperature is greater than the range of a, it means that the temperature inside the cavity of the battery housing is high, indicating that the temperature on the upper punch die 24 becomes high during continuous stamping work. At this time, transmit the signal to the robotic arm 3, control the robotic arm 3 to drive the second nozzle 44 towards the upper punch die 24, and start the gas source to blow the gas through the second nozzle 44 to the surface of the upper punch die 24 to cool it, avoiding the upper punch die 24 deforming due to high temperature for a long time and affecting the quality of stamping the battery housing.

[0055] While the temperature sensor 23 is working, the first camera 18 and the second camera 19 respectively take pictures of the cavity where the battery case is formed and the upper punch die 24. The taken pictures are transmitted to the console 2 to identify whether there are impurities on the surface of the battery case and the upper punch die 24. When there are impurities on the upper punch die 24, the console 2 controls the robotic arm 3 to drive the brush 33 to contact the surface of the upper punch die 24 to remove the impurities on the surface of the upper punch die 24. When there are impurities inside the cavity of the battery case, the electromagnetic chuck 21 is first controlled to move out of the cavity of the battery case, and then the robotic arm 3 is started to rotate so that the brush 33 enters the cavity of the battery case. At the same time, the air source is started to spray gas into the cavity of the battery case through the nozzle two 44. The impurities in the cavity of the battery case are removed by the combination of the brush 33 and the air flow. Through this step, the impurities in the cavity where the battery case is formed and on the upper punch die 24 can be removed, avoiding linear scratches during demoulding.

[0056] It should be added that when using the brush 33 for cleaning, the third cylinder 32 is started synchronously to push the connecting table two 43 to move away from the bearing plate two 31, improving the efficiency of removing impurities.

[0057] Furthermore, the console 2 analyzes the frequency change between the number of times of cooling the upper punch die 24 and the number of times of cleaning the upper punch die 24 to analyze the stamping work quality of the stamping machine tool 1:

[0058] Specifically, the time interval between two coolings is recorded in the console 2 as , and the total working duration of the stamping machine tool 1 is set as t. The calculation formula for the frequency change of the number of cooling times is: , where is the ratio of the time of two coolings to the total working duration. When , it indicates that the frequency of the number of times of cooling the upper punch die 24 is fast. When , it indicates that the frequency of the number of times of cooling the upper punch die 24 is normal;

[0059] At the same time, record the number of times of cleaning the upper punch die 24 within time. When the frequency of the number of cooling times is fast and the number of cleaning times is greater than N, it means that the upper punch die 24 on the stamping machine tool 1 is damaged and needs to be replaced. When the frequency of the number of cooling times is fast and the number of cleaning times is less than N, it means that the heat dissipation of the upper punch die 24 on the stamping machine tool 1 is slow. When the frequency of the number of cooling times of the upper punch die 24 is normal and the number of cleaning times is less than N, it means that the quality of the upper punch die 24 is high. When the frequency of the number of cooling times of the upper punch die 24 is normal and the number of cleaning times is greater than N, it means that impurities are easily generated when the upper punch die 24 is stamping.

[0060] When the upper punch die 24 dissipates heat slowly, it is prone to deformation. To ensure the stamping quality, before the next sheet metal stamping, the lead screw drive one and the lead screw drive two are started to control the moving block 15 to move towards the sheet metal, so that the nozzle one 40 on the right side of the moving block 15 moves above the sheet metal. The first pump body 42 is started to spray the lubricating fluid in the storage tank 11 onto the surface of the sheet metal. At the same time, the first motor 39 is controlled to start, and the connecting table one 22 is driven to swing through the bearing plate one 16, increasing the spraying area of the nozzle one 40 so as to increase the contact area between the sheet metal and the lubricating fluid. At the same time, the nozzle two 44 on the robotic arm 3 is aligned with the surface of the upper punch die 24 to increase the cooling time. When the upper punch die 24 is formed with the sheet metal again, the lubricating fluid on the sheet metal further cools the upper punch die 24 through contact, avoiding the influence of the temperature on the upper punch die 24 on the stamping forming quality; when the stamping forming is completed, there is lubricating fluid attached to the upper punch die 24. At this time, the robotic arm 3 is controlled again to further increase the cooling effect on the upper punch die 24.

[0061] When impurities are easily generated when the upper punch die 24 is stamping, it means that the surface roughness of the upper punch die 24 is abnormal, and it is easy to generate frictional debris impurities with the surface of the sheet metal. At this time, in addition to removing the impurities on the surface of the upper punch die 24 through the robotic arm 3, it is also necessary to detect and judge whether there are scratches inside the cavity of the battery case. Specifically, the formed battery case is moved to the placement table 8, and the placement table 8 is lifted under the second camera 19 by controlling the cylinder drive. The second camera 19 takes an image of the cavity of the battery case and transmits it to the control console 2 again. When no scratches are recognized, it means that although the service life of the upper punch die 24 is reduced, it can still be used normally, and only normal maintenance is required. When scratches are recognized, it means that the surface roughness of the upper punch die 24 in this state has become larger, and the upper punch die 24 needs to be replaced to ensure the quality of the punch die. In addition, the staff removes the battery case with scratches.

[0062] It should be noted that while the formed battery case is being moved to the placement table 8 for inspection, the stamping machine tool 1 continues to stamp the next sheet metal. When the next sheet metal is stamped and formed, the moving block 15 is controlled to move towards the stamping machine tool 1 again. The electromagnetic chuck 21 on the right side of the moving block 15 is controlled to adsorb the just-formed battery case, while the electromagnetic chuck 21 on the left side of the moving block 15 adsorbs the battery case without scratches. When both are adsorbed synchronously, the moving block 15 is controlled to move to the left again. The battery case without scratches is moved to the conveyor belt 5 by the electromagnetic chuck 21 on the left to enter the next process, while the just-stamped battery case is moved to the placement table 8 for scratch testing. At this time, the stamping machine tool 1 continues to stamp, and the quality of the battery case is further ensured by this step when moving and transporting the formed battery case.

[0063] It should be added that when the electromagnetic chuck 21 is driven by the moving block 15 to adsorb and move the formed battery housing, the first motor 39 is synchronously started to work, controlling the rotation of the first bearing plate 16, and further driving the adsorbed formed battery housing to rotate through the connecting frame 20 on the first connecting platform 22. If the battery housing falls off the electromagnetic chuck 21 during the rotation and swing process, it indicates that there is a risk of adsorption failure due to excessive roughness at the bottom of the forming cavity of the battery housing. The battery housing can be removed and precisely inspected manually again.
