[0042] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0043] like Figure 1 and Figure 2 As shown, this utility model embodiment provides a handheld cutting and grinding device, including: a handle 1, a cutting component 2, a grinding component 3, and a controller 4. Both ends of the handle 1 are provided with mounting chambers 11. The cutting component 2 is installed in one of the mounting chambers 11, with its cutting head located outside the mounting chamber 11. The grinding component 3 is installed in the other mounting chamber 11, with its grinding head 322 located outside the mounting chamber 11. The controller 4 is installed inside the handle 1 and is electrically connected to the cutting component 2 and the grinding component 3.
[0044] During use, the user holds the cutting and grinding device. For small pieces of carbon traces, either the cutting component 2 or the grinding component 3 can be used to remove them. However, for larger carbon traces, the cutting component 2 should be used first to cut off the carbon trace portion. When the carbon trace is reduced to a smaller size, the grinding component 3 is used to grind it off. During grinding and cutting, the rotation speed of the grinding component 3 and the cutting component 2 can be adjusted according to the size of the carbon trace. This reduces the amount of scrap and debris generated during the cutting and grinding process, maximizing the utilization rate of polycrystalline silicon carbon traces.
[0045] More specifically, such as Figure 1 and Figure 2 As shown, the grinding assembly 3 includes a grinding motor 31 and a grinding element 32. The grinding motor 31 is installed inside the mounting chamber 11, and the output shaft of the grinding motor 31 is positioned facing the outside of the mounting chamber 11. One end of the grinding element 32 is connected to the output shaft of the grinding motor 31 and extends outside the mounting chamber 11. The grinding head 322 of the grinding element 32 has a tapered structure at the end away from the grinding motor 31, and grooves 33 are intersecting on its outer side wall. The surface formed between the grooves 33 is the grinding surface 34.
[0046] When using the device to grind small carbon marks, the grinding motor 31 drives the grinding part 32 to rotate, and the carbon marks are ground off during the rotation of the grinding part 32. During the grinding process, the controller 4 controls the speed of the grinding motor 31, so that the amount of bottom material and debris generated by the grinding part 32 during the grinding process is reduced.
[0047] It should be noted that the polishing surface 34 removes carbon marks.
[0048] In one embodiment, such as Figure 1 and Figure 2 As shown, in order to make it easier for the user to hold the handle 1, the middle part of the handle 1 is the grip part 12, and the grip part 12 is provided with an anti-slip sleeve 13.
[0049] In one embodiment, such as Figure 1 and Figure 2 As shown, in order to facilitate the adjustment of the rotation speed of the cutting component 2 and the grinding component 3, a clearance opening 14 is provided on the outer wall of the handle 1, through which the start button 41 and the speed adjustment button 42 of the cutting component 2 and the grinding component 3 are exposed.
[0050] It should be noted that the speed adjustment button 42 is provided to facilitate the adjustment of the speed of the grinding motor 31 and the cutting motor 21 during use.
[0051] In one embodiment, such as Figure 1 and Figure 2 As shown, the cutting assembly 2 includes a cutting motor 21 and a cutting blade 22. The cutting motor 21 is installed in another mounting chamber 11, and the output shaft of the cutting motor 21 is positioned opposite to the output shaft of the grinding motor 31. The cutting blade 22 is mounted on the output shaft of the cutting motor 21, and the diameter of the cutting blade 22 is larger than the diameter of the handle 1.
[0052] When large carbon marks need to be removed, the cutting motor 21 drives the cutting blade 22 to cut the carbon marks. During the cutting process, the speed of the cutting motor 21 can be adjusted as needed to reduce the amount of scrap and debris on the cutting surface, thereby maximizing the utilization rate of polycrystalline silicon carbon marks.
[0053] In one embodiment, to improve the service life of the cutting blade, the cutting blade 22 is a diamond grinding wheel.
[0054] In one embodiment, such as Figure 1 and Figure 2 As shown, the grinding component 32 includes a connecting rod 321 and a grinding head 322. One end of the connecting rod 321 is detachably connected to the output shaft of the grinding motor 31. The grinding head 322 is disposed at the other end of the connecting rod 321, and the end of the grinding head 322 near the grinding motor 31 converges radially toward the end away from the grinding motor 31.
[0055] To facilitate the grinding of carbon marks by the grinding head 322, the end of the grinding head 322 near the grinding motor 31 is radially converged toward the end away from the grinding motor 31.
[0056] To facilitate the replacement of different sized grinding heads 322, the connecting rod 321 is detachably connected to the output shaft of the grinding motor 31.
[0057] In one embodiment, to improve the service life of the grinding head 322, the grinding head 322 is a diamond grinding head.
[0058] In one embodiment, such as Figure 1 and Figure 2 As shown, the cutting and grinding device further includes a battery 5, which is installed inside the handle 1 and supplies power to the grinding assembly 3 and the cutting assembly 2.
[0059] In order to facilitate power supply to the grinding component 3 and the cutting component 2 during use, a storage battery 5 is installed in the handle 1.
[0060] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
