[0038] See also Figures 1 to 6 This embodiment provides a movable tantalum slit polishing tool for polishing and clamping a tantalum slit sheet 100. The tantalum slit sheet 100 has a side edge 110 to be polished. The movable tantalum slit polishing tool includes a clamping seat 1, a supporting seat 2 and a locking member 3.

[0039] A polished supporting surface 11 is formed on one side of the clamping seat 1 .

[0040] The support seat 2 is disposed in the clamping seat 1 and can move longitudinally relative to the polishing support surface 11 . The support seat 2 is used to support the tantalum slit sheet 100 so that the side edge 110 to be polished is exposed and extends outside the polishing support surface 11 .

[0041] The locking member 3 is connected to the clamping seat 1 and is used to lock the relative positions of the supporting seat 2 and the clamping seat 1 .

[0042] See also Figure 1 , which are the front view and top view of the tantalum slit sheet 100, the top side of the tantalum slit sheet 100 is the side edge 110 to be polished, see Figure 2 , which is a schematic diagram of the splicing of the tantalum slit sheets 100. During the splicing, the sides of two polished tantalum slit sheets 100 need to be butted together so that there is no light leakage after the splicing. Therefore, the polishing of the tantalum slits has extremely high requirements.

[0043] See also Figure 3 The support seat 2 can slide up and down in the clamping seat 1, and one end of the support seat 2 supports the tantalum slit sheet 100, so that the side edge 110 to be polished at the top of the tantalum slit sheet 100 is exposed and parallel to the polishing support surface 11. When the support seat 2 slides, the exposed height of the side edge 110 to be polished also changes accordingly, so as to control the width of the tantalum slit after polishing. During polishing, the polishing instrument moves along the surface of the polishing support surface 11 to polish the side edge 110 of the tantalum slit sheet 100, thereby avoiding the occurrence of side wall tilting or edge collapse. After the locking member 3 locks the relative position of the support seat 2 and the clamping seat 1, the exposed side edge 110 to be polished of the tantalum slit sheet 100 is also fixed, so the width of the tantalum slit sheet 100 after polishing can also be accurately controlled.

[0044] The present embodiment provides a movable tantalum slit polishing tool, which locks the relative positions of the clamping seat and the supporting seat by a locking piece to control the width of the side edge 110 of the tantalum slit sheet 100 to be polished that is exposed from the polishing support surface, thereby accurately controlling the width of the tantalum slit after polishing, and by placing the tantalum slit sheet 100 below the polishing support surface, the polishing tool can only polish the side edge 110 to be polished that is exposed outside the polishing support surface, so as to avoid the occurrence of side wall tilting or edge collapse.

[0045] For further information, see Figure 4 and Figure 5 The clamping seat 1 includes an assembly clamping block 12, and a first limiting groove 121 is provided on the inner side of the clamping block 12. The first limiting groove 121 is connected to the polishing support surface 11 and extends in a direction perpendicular to the polishing support surface 11. The support seat 2 is slidably arranged in the first limiting groove 121.

[0046] Specifically, there are two clamping blocks 12 in a group, and the first limiting grooves 121 on the two clamping blocks 12 are arranged relatively to each other, and the depth of the first limiting grooves 121 needs to be less than half of the thickness of the support seat 2. When the two clamping blocks 12 are tightly attached and locked, the support seat 2 can be fixed in the clamping seat 1 to limit the relative position of the support seat 2 and the clamping seat 1.

[0047] Furthermore, a second limiting groove 21 is formed on one side of the support seat 2 adjacent to the polishing support surface 11, and the second limiting groove 21 is used to place the tantalum slit sheet 100. The second limiting groove 21 can be a groove that matches the outer contour of the tantalum slit sheet 100. When the tantalum slit sheet 100 is placed in the second limiting groove 21, the movement of the tantalum slit sheet 100 can be stuck and restricted.

[0048] For further information, please see Figure 4 and Figure 5 , the clamping block 12 is provided with limiting holes 122 at both ends, and the locking member 3 is arranged through the limiting holes 122. The locking member 3 can lock the relative position of the support seat 2 and the clamping seat 1 by tightening the two clamping blocks 12.

[0049] Furthermore, the locking member 3 includes a bolt and a nut, and the limiting hole 122 is a bolt hole. By passing the bolt through the bolt hole and tightening the nut, the two clamping blocks 12 can be locked.

[0050] For further information, see Figure 7 , and also includes a measuring component 4, which includes a main scale 41 and a vernier scale 42.

[0051] The end of the main ruler 41 is connected to the side of the clamping seat 1 away from the polishing support surface 11.

[0052] The end of the vernier scale 42 is connected to the side of the support seat 2 away from the polishing support surface 11 , and the scale side of the vernier scale 42 is slidably matched with the scale side of the main scale 41 .

[0053] Among them, when the top of the support seat 2 is parallel to the polishing support surface 11, the zero scale of the vernier scale 42 is aligned with the zero scale of the main scale 41. When the tantalum slit sheet 100 is placed on the top of the support seat 2, the support seat 2 can slide longitudinally relative to the polishing support surface 11. At this time, the vernier scale 42 will slide relative to the main scale 41. The sliding distance of the support seat 2 can be accurately calculated by reading the zero scale of the vernier scale 42 and the number of grids on the main scale 41. The reading method is the same as the vernier caliper method, so it is not repeated in this embodiment.

[0054] Furthermore, the specification of the vernier scale 42 is 9 mm ten-degree, 19 mm twenty-degree or 49 mm fifty-degree, so that the measurement accuracy reaches 0.1 mm, 0.05 mm or 0.02 mm.

[0055] Furthermore, the polishing support surface 11 is a plane, and the side edge 110 to be polished is parallel to the polishing support surface 11 to ensure that the side edge of the tantalum slit sheet 100 is vertical after polishing.

[0056] Furthermore, the thickness of the support base 2 is consistent with the thickness of the tantalum slit sheet 100 to ensure that the tantalum slit sheet 100 is not easy to fall off after clamping.

[0057] Furthermore, the size of the bolts, nuts and bolt holes is M5 to match the overall size of the polishing tool. When the size of the tantalum slit sheet 100 is different, the sizes of the clamping seat 1, the support seat 2, the bolts, nuts and bolt holes may also be different.

[0058] Working principle: the support seat 2 is placed in the first limiting groove 121 on the inner side of the clamping block 12 and can move along the slotting direction of the first limiting groove 121. The tantalum slit sheet 100 is inserted into the second limiting groove 21 of the support seat 2 and makes the side edge 110 to be polished face the polishing support surface 11. When the support seat 2 is slid in the direction close to or away from the polishing support surface 11, the side edge 110 to be polished can be exposed outside the polishing support surface 11. When the exposed height is adjusted to meet the requirements, the two clamping blocks 12 are fitted so that the support seat 2 is located in the two first limiting grooves 121. At this time, the two clamping blocks 12 can be locked with bolts to fix the height of the side edge 110 to be polished exposed outside the polishing support surface 11. During polishing, the polishing tool can only polish the side edge 110 to be polished outside the polishing support surface 11, thereby avoiding tilting or collapsing edges.
