[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.
[0027] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 An embodiment of the present application provides an electrode needle grinding device, including a fixing member 100, a grinding platform 300 and a sandpaper discharge assembly 400.
[0028] See also Figure 1 , the fixing part 100 is used to install the electrode needle 200. The fixing part 100 is installed on the polishing platform 300. For example, the fixing part 100 is a plate-like structure, the polishing platform 300 is also a plate-like structure, and the fixing part 100 is connected to the polishing platform 300 at a certain angle. The angle between the fixing part 100 and the polishing platform 300 is less than 90°, so that the end of the electrode needle 200 is tilted toward the surface of the polishing platform 300. The fixing part 100 and the polishing platform 300 can adopt a split structure, and the fixing part 100 is connected to the polishing platform 300 by bolt connection or clamping. The fixing part 100 and the polishing platform 300 can also be formed as an integral structure.
[0029] See also Figure 1 、 Figure 2 and Figure 5The sandpaper unwinding assembly 400 includes a unwinding mechanism 410 and a rewinding mechanism 420. The unwinding mechanism 410 is used to unwind sandpaper 500, while the rewinding mechanism 420 is used to rewind discarded sandpaper 500. The unwinding and rewinding mechanisms 410 and 420 tension the sandpaper 500 on the side of the polishing platform 300 facing the electrode needle 200. The polishing platform 300 has a first side 310 and a second side 320. The sandpaper 500 drawn by the unwinding mechanism 410 adheres to the first side 310, is drawn along the surface of the polishing platform 300 from the second side 320, and is wound around the rewinding mechanism 420. In some embodiments, the first and second sides 310, 320 have curved surfaces. These curved surfaces reduce resistance at corners of the sandpaper 500, facilitating movement of the sandpaper 500. In some embodiments, the first side 310 and the second side 320 are provided with limiting notches, the width of which matches the width of the sandpaper 500. The limiting notches restrict the movement of the sandpaper 500 along the width direction of the sandpaper 500, thereby reducing the probability of wrinkling of the sandpaper 500 and improving the sanding effect.
[0030] In the embodiment of the present application, the electrode needle is polished by the electrode needle polishing device, which reduces the probability of uneven discharge caused by electrode needle oxidation, which affects welding quality, and thus increases the service life of the electrode needle. The sandpaper 500 is retracted and released by the discharge mechanism 410 and the reeling mechanism 420, which is simple to operate and highly automated. The sandpaper 500 is tensioned on one side of the polishing platform 300, reducing the probability of wrinkling of the sandpaper 500 during polishing of the electrode needle 200, which affects the polishing effect.
[0031] In some embodiments, see Figure 2 、 Figure 4 and Figure 5 The discharge mechanism 410 includes a pressing plate 411 and an elastic member 412. The pressing plate 411 is arranged on the side of the polishing platform 300 away from the electrode needle 200, and the pressing plate 411 and the polishing platform 300 form a gap 413 for the sandpaper 500 to pass through. The elastic member 412 is connected to the pressing plate 411, and the elastic restoring force of the elastic member 412 acts on the pressing plate 411, so that the pressing plate 411 presses the sandpaper 500 toward the polishing platform 300 side. The sandpaper 500 passes through the gap 413 between the pressing plate 411 and the back side of the polishing platform 300, and the pressing plate 411 always presses the sandpaper 500, reducing the probability of the sandpaper 500 loosening. The discharge mechanism 410 is arranged on the back side of the polishing platform 300, with a reasonable space design and a compact structure.
[0032] In some embodiments, see Figure 2 、 Figure 4 and Figure 5The pressure plate 411 includes a first end and a second end. The first end is rotatably connected to the polishing platform 300. An elastic member 412 has one fixed end and the other end abutting the second end. The first end of the pressure plate 411 is rotatably connected to the polishing platform 300. Rotating the pressure plate 411 adjusts the size of the gap 413 between the second end and the polishing platform 300, facilitating the passage of sandpaper 500 through the gap 413. The elastic member 412 is a spring. One end of the spring abuts the side of the pressure plate 411 facing away from the polishing platform 300, while the other end is fixed.
[0033] In some embodiments, see Figure 4 The first end of the pressing plate 411 is provided with a curved surface 414. The first end of the pressing plate 411 is a hollow cylindrical structure, with both sides of the first end rotatably connected to the sanding platform 300 via a rotating shaft. Sandpaper 500 enters through the curved surface 414 and exits through the second end of the pressing plate 411. The smooth curved surface 414 provides minimal resistance to the movement of the sandpaper 500, preventing cuts.
[0034] In some embodiments, see Figure 2 The sandpaper discharge assembly 400 includes a first mounting bracket 430 , which is detachably connected to a side of the grinding platform 300 away from the fixing member 100 , and the discharge mechanism 410 is mounted on the first mounting bracket 430 .
[0035] For example, see Figure 2 The first mounting bracket 430 includes a first mounting plate 431 and a second mounting plate 432, and the first mounting plate 431 and the second mounting plate 432 are arranged relative to each other at a distance. The first mounting plate 431 and the second mounting plate 432 are detachably fixedly connected to the grinding platform 300 by screws. The pressing plate 411 is located between the first mounting plate 431 and the second mounting plate 432. The first end of the pressing plate 411 is rotatably connected to the first mounting plate 431 and the second mounting plate 432. An installation space is provided on the first mounting plate 431 and the second mounting plate 432, and the elastic member 412 is located in the installation space, one end of the elastic member 412 abuts against the first mounting plate 431 or the second mounting plate 432, and the other end abuts against the bottom surface of the pressing plate 411 near the second end.
[0036] In the embodiment of the present application, the discharge mechanism 410 is detachably connected to the polishing platform 300 via the first mounting bracket 430 , which has a simple structure and facilitates installation and disassembly of the discharge mechanism 410 .
[0037] In some embodiments, see Figure 5The unloading mechanism 410 includes an unloading roller 415, which is mounted on the side of the polishing platform 300 facing away from the fixed member 100. Sandpaper 500 is wound around the unloading roller 415. The unloading roller 415 can also be mounted on the back side of the polishing platform 300. The height of the unloading roller 415 is lower than that of the pressure plate 411. The sandpaper 500 discharged from the unloading roller 415 is flattened and taut by the pressure plate 411 and then tensioned on the front side of the polishing platform 300. The unloading roller 415 unloads the sandpaper 500 and cooperates with the winding mechanism 420 to facilitate the tensioning of the sandpaper 500.
[0038] In some embodiments, see Figure 2 and Figure 5 The rewinding mechanism 420 includes a rewinding roller 421, which is mounted on a side of the polishing platform 300 facing away from the fixing member 100. Sandpaper 500 is wound around the rewinding roller 421. The rewinding roller 421 is located on the back side of the polishing platform 300, near the second side 320 of the polishing platform 300. Discarded sandpaper 500 is rewound by the rewinding roller 421, making it easier to replace the sandpaper.
[0039] In some embodiments, see Figure 2 and Figure 5 The sandpaper unloading assembly 400 includes a second mounting bracket 440 , which is detachably connected to a side of the grinding platform 300 away from the fixing member 100 , and the receiving roller 421 is mounted on the second mounting bracket 440 .
[0040] For example, see Figure 2 and Figure 5 The second mounting bracket 440 includes a third mounting plate 441 and a fourth mounting plate 442, which are removably mounted to the back of the grinding platform 300 using screws. The third and fourth mounting plates 441, 442 are spaced apart from each other. The receiving roller 421 is mounted between the third and fourth mounting plates 441, 442. One end of the receiving roller 421 is rotatably connected to the third mounting plate 441, and the other end is rotatably connected to the fourth mounting plate 442. The receiving roller 421 is installed at a lower height than the unwinding mechanism 410.
[0041] In the embodiment of the present application, the receiving roller 421 is installed through the second mounting bracket 440, which facilitates the installation and disassembly of the receiving roller 421 and facilitates maintenance.
[0042] In some embodiments, see Figure 2 and Figure 5 The receiving roller 421 has a through hole 423 extending radially therethrough, and one end of the sandpaper 500 passes through the through hole 423 and is wound around the receiving roller 421 .
[0043] In the embodiment of the present application, one end of the sandpaper 500 passes through the through hole 423 and is then wrapped around and fixed to the surface of the receiving roller 421, ensuring the tension of the sandpaper 500 when it is rolled up, which is beneficial for the receiving roller 421 to roll up the sandpaper 500 and tension the sandpaper 500.
[0044] In some embodiments, see Figure 1 The fixture 100 is mounted on one side of the polishing platform 300 and is provided with a plurality of spaced mounting holes 110. The fixture 100 is a plate-like structure, with the plurality of mounting holes 110 spaced along its length. Electrode needles 200 are mounted within the mounting holes 110. The electrode needle polishing device can polish multiple electrode needles 200, improving polishing efficiency. Along the length of the fixture 100, the spacing between any two adjacent mounting holes 110 is uniform.
[0045] In some embodiments, see Figure 1 The mounting hole 110 is tilted, with one end of the mounting hole 110 closer to the polishing platform 300 than the other end. The mounting hole 110 is tilted along its length, and accordingly, the electrode needle 200 mounted within the mounting hole 110 is tilted. The tip of the electrode needle 200 contacts the sandpaper 500 on the polishing platform 300, polishing only the oxide on the end of the electrode needle 200, thereby improving polishing accuracy.
