Description

Technical Field

[0001] This application relates to the field of mechanical equipment, and in particular to a side punching mechanism for a lead-acid battery casing. Background Technology

[0002] Lead-acid battery casings contain vertically arranged separators. Punching these separators is a crucial manufacturing step. In some applications, a swing-type punching method is used. The punching die swings at a certain angle during the punching process, allowing it to penetrate the battery casing and punch the separator. However, because the contact between the punching die and the separator is not perfectly perpendicular, burrs often remain at the edges of the punched holes. These burrs not only affect the quality of the separator but may also adversely impact battery performance.

[0003] Therefore, this application studies a side punching mechanism for a lead-acid battery casing, which can avoid burrs, improve the quality of the separator, and ensure the performance of the battery. Utility Model Content

[0004] In order to avoid burrs, improve the quality of the separator, and ensure the performance of the battery, this application provides a side punching mechanism for a lead-acid battery casing.

[0005] This application provides a side punching mechanism for a lead-acid battery casing, which adopts the following technical solution:

[0006] A side punching mechanism for a lead-acid battery casing includes a driving member, a connecting rod assembly, and a positioning seat. The connecting rod assembly includes a first connecting rod, and the driving member drives the first connecting rod to move horizontally. A punching component is connected to the first connecting rod. The positioning seat is disposed on one side of the punching component, and a limiting groove is vertically formed on the positioning seat. During punching, a partition is inserted into the limiting groove for limitation, and the punching component is simultaneously located on one side of the partition. The driving member drives the first connecting rod to drive the punching component to punch the partition.

[0007] By adopting the above technical solution, the first connecting rod is driven by the driving component to drive the punching component to punch. The punching component moves in a horizontal linear motion, and the separator is limited to the vertical direction by the limiting groove. Therefore, when the punching component punches the separator horizontally, it is in a completely vertical state. In addition, the limiting groove can also make the separator be punched stably, thereby avoiding burrs on the edge of the hole, improving the surface quality of the separator, and ensuring the performance of the battery.

[0008] Optionally, the positioning seat has a clearance hole that penetrates the limiting groove, and the clearance hole corresponds to the position of the punched part.

[0009] By adopting the above technical solution, the clearance hole can further guide the punching position of the punched part, further ensure the stability of punching, and also avoid the displacement or deformation of the partition due to the impact force of the punched part, thereby further improving the punching quality.

[0010] Optionally, the linkage assembly further includes a second linkage, one end of which is rotatably connected to the output end of the drive member, and the other end of which is rotatably connected to the first linkage; during punching, the drive member drives the second linkage to rotate and pushes the first linkage to move in the horizontal direction, thereby driving the punching member to punch holes in the partition.

[0011] By adopting the above technical solution, the second link can disperse the impact force on the partition, so that the impact force can be transmitted to the punching part more evenly, ensuring the stable horizontal movement of the punching part during punching and improving the punching quality.

[0012] Optionally, it also includes a mounting base, the mounting base being provided with a rotating rod, the rotating rod passing through the side of the second connecting rod near the first connecting rod, and the second connecting rod being rotatably connected to the rotating rod, and the end of the driving member away from the second connecting rod being rotatably disposed.

[0013] By adopting the above technical solution, the setting of the rotating rod effectively limits the swaying or deviation of the second link during the movement, making the movement trajectory of the punching part more accurate and further improving the stability of punching.

[0014] Optionally, the drive member and the first link are located on the same side of the second link.

[0015] By adopting the above technical solutions and optimizing the spatial layout, the footprint of the equipment can be reduced, saving space.

[0016] Optionally, it also includes a guide rod, which is horizontally arranged, and the first connecting rod is sleeved on the guide rod and slidably connected to the guide rod.

[0017] Optionally, it also includes a fixed base, which has a sliding groove, and the first connecting rod is slidably connected in the sliding groove. The positioning seat is detachably installed on the fixed base.

[0018] Optionally, the positioning seat is also provided with a guide groove, and during punching, the punching part approaches the positioning seat and enters the guide groove.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] The first connecting rod is driven by the driving component to punch the part. The punching part moves horizontally in a straight line. The separator is limited to the vertical direction by the limiting groove. Therefore, when the punching part punches the separator horizontally, it is in a completely vertical state. In addition, the limiting groove can also make the separator be punched stably, thereby avoiding burrs on the edge of the hole, improving the surface quality of the separator, and ensuring the performance of the battery.

[0021] The clearance hole can further guide the punching position of the punched part, further ensure the stability of punching, and also prevent the partition from shifting or deforming due to the impact force of the punched part, thus further improving the punching quality.

[0022] The second link can disperse the impact force on the partition, so that the impact force can be transmitted to the punching part more evenly, ensuring the stable horizontal movement of the punching part during punching and improving the punching quality. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0028] This application discloses a side punching mechanism for a lead-acid battery casing. (Refer to...) Figure 1The side punching mechanism of the lead-acid battery casing includes a driving component 1, a connecting rod assembly 2, and a positioning seat 5. The connecting rod assembly 2 includes a first connecting rod 21. In this embodiment, the driving component 1 is a cylinder, which drives the first connecting rod 21 to move horizontally. A punching component 4 is connected to the first connecting rod 21. In this embodiment, the punching component 4 includes an integrally formed punching seat 41 and a cylindrical punching head 42. The punching head 42 is used for punching. The punching seat 41 and the first connecting rod 21 are fixed by bolts. In other embodiments, they can also be fixed by snap-fitting, bonding, or other methods. The positioning seat 5 is disposed on one side of the punching component 4. A limiting groove 6 is vertically formed on the positioning seat 5 to limit the position of the partition.

[0029] During punching, the separator is inserted into the limiting groove 6 for limitation. At this time, since the positioning seat 5 is located on one side of the punching part 4, when the separator is inserted, the punching part 4 also enters the lead-acid battery casing. The punching part 4 is simultaneously located on one side of the separator. The driving component 1 drives the first connecting rod 21 to drive the punching part 4 to punch the separator. Therefore, by limiting the separator vertically through the limiting groove 6, the driving component 1 pushes the punching part 4 horizontally, so that the punching part 4 can punch the separator completely vertically, effectively avoiding burrs, thereby improving the quality of the separator and ensuring the performance of the battery.

[0030] In some embodiments, the positioning seat 5 has a clearance hole 7 that penetrates the limiting groove 6, and the clearance hole 7 corresponds to the position of the punching part 4. In this embodiment, clearance holes 7 are provided on both sides of the positioning seat 5, that is, the punching head 42 can pass through the clearance hole 7 on one side to punch the partition and then pass through the clearance hole 7 on the other side. This allows the length of the positioning seat 5 to extend below the punching position, which can better stabilize the partition. Furthermore, by corresponding with the punching part 4, the clearance hole 7 provides a punching channel for the punching part 4, making the punching position more accurate. At the same time, the limiting position of the positioning seat 5 on both sides around the punching position can better avoid the deformation of the partition and further improve the punching quality.

[0031] In some embodiments, the linkage assembly 2 further includes a second linkage 22, one end of which is rotatably connected to the output end of the drive member 1, in this embodiment being rotatably connected to the end of the telescopic rod of the cylinder. The other end of the second linkage 22 is rotatably connected to the first linkage 21. During punching, the drive member 1 drives the second linkage 22 to rotate and pushes the first linkage 21 to move horizontally, thereby driving the punching member 4 to punch the partition. The second linkage can disperse the impact force, making the partition more evenly stressed during punching.

[0032] Reference Figure 1 and Figure 2In some embodiments, a mounting base 8 is also included, which is provided with a rotating rod 9. The rotating rod 9 passes through the second connecting rod 22 on the side near the first connecting rod 21, and the second connecting rod 22 is rotatably connected to the rotating rod 9. The end of the driving member 1 away from the second connecting rod 22 is rotatably disposed. The driving member 1 drives the second connecting rod 22 to rotate along the rotating rod 9. When the extension rod of the cylinder extends, it pushes out the second connecting rod 22, and the second connecting rod 22 rotates along the rotating rod 9. On the other side, it pushes the punching part 4 of the first connecting rod 21 toward the positioning seat 5, thereby realizing punching. When the extension rod of the cylinder retracts, it pulls back the second connecting rod 22, and the second connecting rod 22 rotates along the rotating rod 9. On the other side, it pulls out the punching part 4 of the first connecting rod 21 away from the positioning seat 5, and inserts the next partition into the limiting groove 6 to continue punching.

[0033] Continue to refer to Figure 2 In some embodiments, the drive member 1 and the first connecting rod 21 are located on the same side of the second connecting rod 22. This embodiment also includes a mounting plate, with the mounting base 8 screwed to the bottom of the mounting plate. The first connecting rod 21 is located below the mounting plate, and the mounting plate has a through slot. The second connecting rod 22 passes through the through slot from top to bottom, with one end connected to the first connecting rod 21, and the other end located above the mounting plate and connected to the drive member 1. The drive member 1 is rotatably connected to the top of the mounting plate, which allows for full utilization of space, saves floor space, and optimizes the layout.

[0034] Refer again Figure 1 In some embodiments, a guide rod 10 is also included. The guide rod 10 is horizontally arranged. In this embodiment, one end of the guide rod 10 is connected to the mounting base 8, and the other end is connected to the bottom of the mounting plate. The first connecting rod 21 is sleeved on the guide rod 10 and slidably connected to the guide rod 10. The guide rod 10 enables the first connecting rod 21 to move horizontally more stably, improving the stability of the punching.

[0035] Reference Figure 2 In some embodiments, a fixing base 11 is also included. In this embodiment, the fixing base 11 is installed below the mounting plate. The fixing base 11 has a sliding groove 12, and the guide rod 10 is also disposed through the sliding groove 12. The first connecting rod 21 is slidably connected in the sliding groove 12, and the other side can cooperate. Figure 1 View. The positioning seat 5 is detachably installed on the fixed seat 11. In this embodiment, the positioning seat 5 has a "U" shaped structure, with both ends inserted into the fixed seat 11 and screwed to the fixed seat 11. The concave surface is in contact with the lower surface of the first connecting rod 21.

[0036] Reference Figure 3 In some embodiments, the positioning seat 5 is also provided with a guide groove 13. During punching, the punching part 4 approaches the positioning seat 5 and enters the guide groove 13. In this embodiment, the punching seat 41 partially enters the guide groove 13. The guide groove 13 can better guide and limit the punching part 4, making the punching of the partition plate more stable.

[0037] The implementation principle of the side punching mechanism of the lead-acid battery casing in this application embodiment is as follows: the first connecting rod 21 is driven by the driving component 1 to drive the punching component 4 to punch. The punching component 4 moves horizontally in a straight line, and the separator is limited to the vertical direction by the limiting groove 6. Therefore, when the punching component 4 punches the separator horizontally, it is in a completely vertical state. In addition, the limiting groove 6 can also make the separator be punched stably, thereby avoiding burrs on the edge of the hole, improving the surface quality of the separator, and ensuring the performance of the battery.

[0038] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
