Description

Technical Field

[0001] The utility model relates to the technical field of lead-acid battery grid production, in particular to a device for trimming flash and burrs of a lead strip of a battery. Background Art

[0002] The grid is the main component of the lead-acid battery and the collector skeleton of the electrode. It conducts, collects and evenly distributes current. It also supports the active material and is the carrier of the active material. The advantages of continuous casting and rolling grids, such as strong density and corrosion resistance, have gradually replaced the traditional weight casting grids. The continuous casting and rolling grids first make the lead strips, and then punch them into grids. In the process of manufacturing the lead strips, the basic lead strips are rolled several times into ultra-thin lead strips. The basic lead strips come out of the lead pot through rollers. The outer edges of the basic lead strips often have lead flash, etc. If they are not trimmed, these flashes will cause the lead strips to be delaminated after multiple rolling, resulting in quality problems such as poor corrosion resistance of the grid bars.

[0003] The patent document with application number CN202121142296.2 and invention name "A device for trimming flash and burrs on battery lead strips" discloses a device that can use a cutter to remove flash and burrs on both sides of the lead strip. During operation, the lead strip is passed through the gap between paired rollers. When the lead strip reaches the cutter, the guide head corrects the direction of the lead strip and allows the lead strip to be inserted into the cutter. The upper and lower sides of the lead strip are in contact with the blade, and the lead strip is trimmed of flash and burrs when it passes through the cutter.

[0004] However, since the lead strip is relatively soft, during the process of the cutter cutting the burrs and flashes of the lead strip, the patent only relies on the guide head to straighten the direction of the lead strip entering the blade, and the straightened portion of the lead strip during movement is relatively small. During the movement of the lead strip, the burrs and flashes above and below the lead strip, as well as the burrs and flashes on the side of the lead strip, are sheared and cut by the cutter at the same time. When the thickness of the burrs and flashes is large, the lead strip is easily deformed by the resistance of the cutter. After the burrs and flashes of the lead strip are cut by the cutter, the side of the lead strip is easily deformed, which in turn affects the quality of subsequent grid production. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a device for trimming the flash and burrs of the lead strip of a battery, which can effectively remove the burrs and flashes of the lead strip, and can effectively straighten the lead strip in the process of removing the burrs and flashes of the lead strip to avoid deformation of the side of the lead strip. In order to achieve the above purpose, the technical solution provided by the utility model is:

[0006] A device for trimming flash and burrs of a lead strip of a storage battery comprises a platform, two brackets are fixed on the platform, and a first drive assembly and a second drive assembly are respectively arranged in the two brackets. The first drive assembly and the second drive assembly can drive the lead strip to move, and the second drive assembly is opposite to the movement direction of the lead strip relative to the first drive assembly. Two cutting assemblies are arranged on the platform between the two brackets, and the two cutting assemblies are located between the first drive assembly and the second drive assembly. The lead strip is located between the two cutting assemblies. The cutting assembly comprises a fixed block fixed on the platform, and two scrapers are fixed on one side of the fixed block facing the second drive assembly. One end of the scraper away from the fixed block is inclined toward the center of the lead strip. The two scrapers are symmetrically arranged up and down, and the lead strip is located between the two scrapers. The lead strip is in sliding contact with the scraper, and a blade is processed on the side of the scraper away from the center of the lead strip.

[0007] A milling cutter is rotatably connected between the two scrapers, and a second motor driving the milling cutter to rotate is fixed on any scraper, and the outer edge of the milling cutter contacts the side wall of the lead belt on one side thereof.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] 1. The utility model provides a scraper, and the end of the scraper away from the fixed block is inclined toward the center of the lead tape, and the scraper is in sliding contact with the lead tape. Therefore, during the process of scraping off burrs and flash on the upper and lower sides of the side of the lead tape, and before the blade of the scraper cuts the burrs and flash on the lead tape, the scraper part can always effectively straighten the lead tape to prevent the side of the lead tape from being deformed due to the resistance of the scraper.

[0010] 2. By setting the first drive assembly and the second drive assembly, and the cutting assembly is located between the first drive assembly and the second drive assembly, the first drive assembly and the second drive assembly drive the lead tape at the same time, and the lead tape is simultaneously driven by the driving force of the first drive assembly and the second drive assembly, so that the stability of the lead tape during movement is good. When the cutting assembly processes the burrs and flash on the side of the lead tape between the first drive assembly and the second drive assembly, it can avoid the change in the direction of movement of the lead tape after the resistance of the scraper is applied. The first drive assembly and the second drive assembly can clamp and drive the lead tape on both sides of the cutting assembly. When the burrs and flash on the side of the lead tape are thick, it can avoid the deformation of the lead tape after the scraper generates greater resistance to the lead tape.

[0011] 3. Use the scrapers on the upper and lower sides to scrape off the burrs and flash on the upper and lower sides of the lead tape, and use the rolling cutter to grind and remove the burrs and flash on the side of the lead tape. This can reduce the resistance encountered by the lead tape during movement and prevent the side of the lead tape from being deformed due to large shear force.

[0012] 4. By setting a limit wheel, the movement direction of the lead belt can be further limited to avoid excessive grinding of the lead belt by the rolling milling wheel. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0032] Embodiment 1:

[0033] Reference Figure 1-Figure 2 As shown, a device for trimming flash and burrs of battery lead strips includes a platform 1, two brackets 2 are fixed on the platform 1, and a first drive assembly and a second drive assembly are respectively arranged in the two brackets 2. The first drive assembly and the second drive assembly can drive the lead strip 15 to move, and the second drive assembly is opposite to the movement direction of the lead strip 15 relative to the first drive assembly.

[0034] In this embodiment, the first driving assembly is located on the left side, the second driving assembly is located on the right side, and the lead belt 15 moves from right to left.

[0035] The first driving assembly includes two guide rollers 3 rotatably connected to one of the brackets 2, and the two guide rollers 3 are symmetrically arranged up and down. There is a positioning gap between the two guide rollers 3 for the lead belt 15 to pass through. A first motor 4 is fixed to the bracket 2 where the guide rollers 3 are located, and the first motor 4 is connected to any one of the guide rollers 3.

[0036] The second driving assembly includes two rotating rods 5 rotatably connected to another bracket 2, and the two rotating rods 5 are symmetrically arranged up and down. A plurality of guide wheels 6 are fixed on each rotating rod 5, and the guide wheels 6 on the upper and lower rotating rods 5 correspond to each other, and there is a positioning gap between the upper guide wheel 6 and the lower guide wheel 6 for the lead tape 15 to pass through. A first motor 4 is fixed on the bracket 2 where the rotating rod 5 is located, and the first motor 4 is connected to any one of the rotating rods 5.

[0037] Two cutting assemblies are arranged on the platform 1 between the two brackets 2, and the two cutting assemblies are located between the first driving assembly and the second driving assembly. The lead belt 15 is located between the two cutting assemblies.

[0038] By providing a first drive assembly and a second drive assembly, and with the cutting assembly located between the first drive assembly and the second drive assembly, the first drive assembly and the second drive assembly drive the lead belt 15 simultaneously, and the lead belt 15 has good stability during movement.

[0039] When the cutting assembly processes the burrs and flashes on the side of the lead tape 15 between the first driving assembly and the second driving assembly, it can prevent the lead tape 15 from changing its moving direction after being resisted by the cutting assembly.

[0040] When the burrs and flashes on the side of the lead strip 15 are relatively thick, it is possible to avoid that the scraper 8 generates a large resistance to the lead strip 15, which causes the lead strip 15 portion between the first drive assembly and the second drive assembly to be deformed.

[0041] The cutting assembly includes a fixed block 7 fixed on the platform 1, and two scrapers 8 are fixed on one side of the fixed block 7 facing the second driving assembly. The end of the scraper 8 away from the fixed block 7 is inclined toward the center of the lead belt 15. The two scrapers 8 are symmetrically arranged up and down, and the lead belt 15 is located between the two scrapers 8. The lead belt 15 is in sliding contact with the scraper 8, and a blade is processed on the side of the scraper 8 away from the center of the lead belt 15.

[0042] A hob 10 is rotatably connected between the two scrapers 8. A second motor 11 driving the hob 10 to rotate is fixed on any one of the scrapers 8. The outer edge of the hob 10 contacts the side wall of the lead belt 15 on one side thereof.

[0043] When the lead tape 15 is driven by the first driving assembly and the second driving assembly, the lead tape 15 moves to the left. When the burrs and flashes on the upper and lower sides of the side of the lead tape 15 come into contact with the blades of the upper and lower scrapers 8, the blades of the upper and lower scrapers 8 can scrape off the burrs and flashes on the upper and lower sides of the side of the lead tape 15.

[0044] Before the burrs and flashes on the upper and lower sides of the side of the lead strip 15 come into contact with the blade of the scraper 8, and during the process of the scraper 8 scraping off the burrs and flashes on the lead strip 15, the scraper 8 can straighten the lead strip 15. During the process of the scraper 8 scraping off the burrs and flashes on the lead strip 15, the side of the lead strip 15 can be prevented from being deformed due to the resistance of the scraper 8.

[0045] The scrapers 8 on the upper and lower sides are used to scrape off the burrs and flash on the upper and lower sides of the lead strip 15. The hobbing cutter 10 is used to grind off the burrs and flash on the side of the lead strip 15. This can reduce the resistance of the lead strip 15 during movement and prevent the side of the lead strip 15 from being deformed due to a large amount of shear force.

[0046] Embodiment 2:

[0047] Based on Example 1, refer to Figure 2 As shown, the upper and lower scrapers 8 located on the same side are fixedly connected by a plurality of connecting frames 9, and the connecting frames 9 are in an inverted U shape.

[0048] The connecting frame 9 can improve the stability of the scraper 8 when removing burrs and flashes on the lead strip 15.

[0049] Embodiment three:

[0050] Based on Example 1, refer to Figure 2 As shown, the ends of the upper and lower scrapers 8 on the same side away from the fixed block 7 are fixed with guide blocks 14, the end of the upper guide block 14 away from the scraper 8 is curved upward, and the end of the lower guide block 14 away from the scraper 8 is curved downward.

[0051] During the movement of the lead tape 15 , the guide block 14 can guide the lead tape 15 entering between the upper and lower scrapers 8 to prevent the end of the scraper 8 away from the fixed block 7 from scratching the lead tape 15 .

[0052] Embodiment 4:

[0053] Based on Example 1, refer to Figure 2 As shown, the fixing block 7 is provided with a groove 12 on one side facing the lead tape 15, and a limiting wheel 13 is rotatably connected in the groove 12, and the limiting wheel 13 is in rolling contact with the side edge of the lead tape 15 on one side thereof.

[0054] By providing the limiting wheel 13 , the moving direction of the lead belt 15 can be further limited, thereby preventing the milling wheel from excessively grinding the lead belt 15 .
