Abstract
Description
Technical Field
[0001] This utility model relates to the field of crystal rod wire cutting technology, and in particular to a crystal rod cutting device. Background Technology
[0002] Indium phosphide (IP) substrates have applications in the manufacture of high-frequency, high-power devices, fiber optic communications, wireless transmission, radio astronomy, and other radio frequency (RF) devices. RF devices manufactured using IPP substrates have demonstrated excellent performance in applications such as satellites and radar. They are highly competitive in the RF front-end of radar and communication systems and in analog / mixed-signal wide-bandwidth circuits, making them suitable for applications such as high-speed data processing and high-precision wide-bandwidth A / D conversion. IPP substrates are obtained by dicing crystal rods into wafers. Current crystal rod dicing equipment uses a pair of dicing wheels to drive the dicing wire to cut the crystal rod. If multiple dicing wires are used, the transmission power of the dicing wire will be insufficient, resulting in unstable dicing wire movement. If only one dicing wire is used, the dicing efficiency will be low. Utility Model Content

These terms are used solely for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. That is, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. Furthermore, unless otherwise stated, "a plurality of" means two or more.
[0029] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.
[0030] like Figures 1-5 As shown, the crystal rod cutting device of this utility model embodiment includes: a guide rail 1, a fixture 2, a drive unit 3, and a cutting assembly 4. The guide rail 1, the drive unit 3, and the cutting assembly 4 are all installed in the working area, and exemplaryly, they are all installed on a frame to maintain stable operation.
[0031] The fixture 2 is slidably mounted on the guide rail 1, and the fixture 2 is used to mount the crystal rod 5. Specifically, the fixture 2 has a groove, and the crystal rod 5 is bonded to the groove of the fixture 2.
[0032] The drive unit 3 includes a first drive source 31 and a drive gear 32. The drive gear 32 is mounted on the drive end of the first drive source 31, and there are two drive units 3. Specifically, the first drive source 31 is mounted on the frame.
[0033] The cutting assembly 4 has multiple sets arranged from the outside to the inside. Each cutting assembly 4 includes a cutting line 41 and two spaced-apart cutting units 42. The cutting lines 41 of each cutting assembly 4 are spaced apart. Each cutting unit 42 includes a guide wheel 421, a drive shaft 422, a driven gear 423, and two bearing seats 424. The guide wheel 421 is mounted on the drive shaft 422, and both ends of the drive shaft 422 are rotatably connected to the two bearing seats 424. One end of the drive shaft 422 passes through the bearing seat 424 and connects to the driven gear 423. The peripheral wall of the guide wheel 421 has a guide groove 425. The cutting line 41 is installed in the guide groove 425 of the guide wheel 421 of the two cutting units 42. The driven gears 423 of adjacent sets of cutting assemblies 4 mesh with each other, thus ensuring that each guide wheel 421 can be driven by an independent driven gear 423, guaranteeing the stability of the rotation of the guide wheel 421, and consequently ensuring the stable movement of the cutting line 41. Specifically, the bearing seats 424 are mounted on the frame.
[0034] In this embodiment, the drive gears 32 of the two drive units 3 are meshed with the driven gears 423 of the two cutting units 42 of the outermost cutting assembly 4 in a one-to-one correspondence. The guide rail 1 is used to drive the crystal rod 5 to move towards the cutting line 41 to perform the cutting action. In this way, by driving the driven gears 423 of the outermost cutting assembly, the driven gears 423 of the two cutting units 42 of the remaining cutting assemblies 4 can be driven sequentially from the outside to the inside.
[0035] During operation, the first drive source 31 is activated to drive the drive gear 32 to rotate. The drive gear drives each driven gear 423 to rotate, causing each guide wheel 421 to rotate, which in turn drives each cutting line 41 to move. The guide rail 1 is activated to drive the fixture 2 to move, causing the crystal rod 5 to move toward the cutting line 41 and come into contact with the cutting line 41 to perform the cutting operation. Two adjacent cutting lines 41 cut the crystal rod to form a wafer, which is used as a substrate.
[0036] Based on the above structure, each guide wheel 421 can be independently driven to rotate by the transmission shaft 422, so that each cutting line 41 can move stably, achieving high cutting accuracy and high cutting efficiency.
[0037] like Figure 4 As shown, in some embodiments, each guide wheel 421 has two guide grooves 425 on its peripheral wall, and each set of cutting components 4 includes two cutting lines 41, with equal spacing between adjacent cutting lines 41. It should be noted that the spacing between the multiple cutting lines 41 arranged horizontally in multiple sets of cutting components 4 is equal, thus ensuring that the wafer thickness formed by cutting the crystal rod is consistent.
[0038] like Figure 1As shown, in some embodiments, a frame 6 is included, and the bearing 422 of the cutting unit 41 is mounted on the frame 6. Specifically, four frames 6 are provided, and each cutting assembly 4 has a bearing 424, so that bearings 424 on the same side of multiple sets of cutting assemblies 4 are mounted in one frame 6. Specifically, the bearings 424 are mounted on a frame via the frame 6.
[0039] like Figure 1 As shown, in some embodiments, the guide rail 1 includes a second drive source 11, a transmission base 12, a lead screw 13, and a slider 14. The second drive source 11 is mounted on one end of the transmission base 12, the lead screw 13 is mounted in the transmission base 12, and one end of the lead screw 13 extends out of the transmission base 12 and is connected to the second drive source 11 for transmission. The slider 14 is mounted on the lead screw 13, and the fixture 2 is mounted on the slider 14. Thus, turning on the second drive source 11 can drive the lead screw 13 to rotate, causing the slider 14 to move along the extension direction of the lead screw 13.
[0040] like Figure 1 As shown, in some embodiments, the guide rail 1 includes a coupling 15, and the second drive source 11 is connected to the lead screw 13 via the coupling 15. Thus, the coupling 15 stabilizes the transmission between the second drive source 11 and the lead screw 13.
[0041] like Figure 1 As shown, in some embodiments, a mounting bracket 7 is included, and two guide rails 1 are provided. The mounting bracket 7 is mounted on the sliders 14 of the two guide rails 1, and the fixture 2 is mounted on the mounting bracket 7. In this way, the mounting bracket 7 is driven by the two guide rails 1 to ensure the stable movement of the fixture 2.
[0042] In some embodiments, both the first drive source 31 and the second drive source 11 are motors. Thus, the first drive source 31 can rapidly drive the cutting line 41 to move, and the second drive source 11 can rapidly drive the crystal rod 5 on the fixture 2 to move.
[0043] In some embodiments, the cutting wire 41 is diamond wire. Diamond wire has the advantages of high cutting efficiency, low wear, and low pollution.
[0044] like Figure 1 As shown, in some embodiments, the moving direction of the fixture 2 is perpendicular to the moving direction of the cutting line 41. This facilitates accurate cutting of the crystal rod 5.
[0045] like Figure 1 As shown, in some embodiments, the distance between the two cutting units 42 of the innermost cutting assembly 4 is greater than the diameter of the crystal rod 5. Thus, during the cutting of the crystal rod 5, the cutting units 42 do not obstruct the movement of the crystal rod 5.
[0046] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
