[0029] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0030] like Figures 1 to 6 As shown in the figure, this application provides a carbon nanotube positioning and drilling device, including an end cap 1, a drill jig 2, and a drill sleeve 3. The drill jig 2 has an internal accommodating cavity 21 for placing the carbon nanotube. One end of the drill jig 2 has a first opening 22, which communicates with the accommodating cavity 21. The end cap 1 is movably connected to one end of the drill jig 2, and recessed holes 23 are respectively formed on the side surfaces of both ends of the drill jig 2. The drill sleeve 3 is placed within the recessed holes 23, and the drill sleeve 3 and the recessed holes 23 are clearance-fitted.

[0031] The carbon nanotube positioning and drilling device of this application embodiment includes an end cap 1, a drill jig 2, and a drill sleeve 3. In use, the carbon nanotube is first placed into the receiving cavity 21 through the first opening 22. Then, the end cap 1 is connected to the drill jig 2, thereby fixing the carbon nanotube inside the drill jig 2. Next, the drill sleeve 3 is placed into the corresponding recessed hole 23, and a drilling tool is used to drill the hole. This application embodiment can achieve precise drilling of the carbon nanotube, ensuring the accuracy of the opening position. The drill sleeve 3 and the recessed hole 23 have a small clearance fit, making it easy for the drill sleeve 3 to be placed into the recessed hole 23.

[0032] In one embodiment, each end of the drill sleeve 3 is provided with at least two groove holes 23, the two groove holes 23 are arranged opposite to each other, and the two groove holes 23 are connected through the receiving cavity 21.

[0033] like Figure 1 As shown, in this embodiment, one end of the drill sleeve 3 has four grooved holes 23, which are opposite to each other, and the four grooved holes 23 are located on different sides of the drill sleeve 3. The other end of the drill sleeve 3 also has four grooved holes 23, which are opposite to each other, and the four grooved holes 23 are located on opposite sides of the drill sleeve 3.

[0034] In one embodiment, the end cap 1 is threadedly connected to the drill jig 2. After the end cap 1 is threadedly connected to the drill jig 2, the carbon tube can be pressed into the receiving cavity 21, so that the carbon tube is fixed in the receiving cavity 21, thereby making it easier to drill.

[0035] In one embodiment, to position the carbon nanotube placed in the receiving cavity 21, a first positioning part 11 is provided on the lower surface of the end cap 1, and the first positioning part 11 is located in the middle of the end cap 1. When the carbon nanotube is placed in the receiving cavity 21 and the end cap 1 is connected to the drill jig 2, one end of the carbon nanotube is sleeved on the first positioning part 11. The first positioning part 11 can be integrally formed with the end cap 1.

[0036] Furthermore, the first positioning part 11 has a frustum structure. The top of the frustum structure is connected to the bottom surface of the end cap 1, and the bottom of the frustum structure protrudes towards the center of the receiving cavity 21. The diameter of the frustum structure gradually decreases from top to bottom. After the carbon tube is placed in the receiving cavity 21 and the end cap 1 is threadedly connected to the drill jig 2, one end of the carbon tube is fitted onto the frustum structure, thereby positioning the carbon tube and automatically centering it on the drill jig 2. Because the diameter of the frustum structure gradually decreases from top to bottom, this frustum structure is suitable for positioning carbon tubes of different sizes.

[0037] In one embodiment, in order to position the other end of the carbon tube, a second positioning part 24 is provided inside the other end of the drill jig 2. The second positioning part 24 is located in the middle of the drill jig 2. When the carbon tube is placed in the accommodating cavity 21, the other end of the carbon tube is sleeved on the second positioning part 24.

[0038] Furthermore, the second positioning part 24 also has a frustum structure. The top of this frustum structure is connected to the bottom of the drill jig 2, and the top of the frustum structure protrudes towards the center of the receiving cavity 21. This frustum structure is the same as the frustum structure of the first positioning part 11, except that the diameter of the frustum structure gradually decreases from the bottom to the top. After the carbon nanotube is placed in the receiving cavity 21, the other end of the carbon nanotube is fitted onto this frustum structure, thereby positioning the carbon nanotube through this frustum structure and automatically centering it on the drill jig 2. Since the diameter of the frustum structure gradually decreases from the bottom to the top, this frustum structure can be used to position carbon nanotubes of different sizes.

[0039] In one embodiment, the drill jig 2 has an elongated groove 25, which is located between the two ends of the drill jig 2 and extends along the length of the drill jig 2. There can be two elongated grooves 25, which are arranged opposite each other. The carbon nanotubes placed in the receiving cavity 21 can be observed through the elongated grooves 25. Furthermore, the elongated grooves 25 save material on the drill jig 2, thereby reducing costs.

[0040] In one embodiment, a first through hole 12 is provided in the middle of the end cap 1. The first through hole 12 is located inside the first opening 22, thereby preventing the carbon tube from falling out of the first through hole 12. A second through hole 26 is provided at the other end of the drill jig 2, and the second through hole 26 communicates with the receiving cavity 21.

[0041] It should be noted that the drill sleeve 3 in this embodiment can be an existing drill sleeve 3 used for drilling carbon tubes. The inner diameter of the groove hole 23 is slightly larger than the diameter of the drill sleeve 3, and the drill sleeve 3 has a drill sleeve hole in the middle for the drill bit to pass through.
