Abstract
Description
Technical Field
[0001] This utility model relates to the field of crystal rod grinding technology, and in particular to a crystal rod straightening 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 processing crystal rods into wafers. During crystal rod processing, the crystal rod is positioned by identifying the lattice orientation within it. This requires straightening the edges of the crystal rod to meet the positioning requirements. Current edge straightening devices use manual methods to move the crystal rod and cannot adjust the edge straightening angle, resulting in low processing efficiency. 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.
[0030] 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.
[0031] like Figures 1-6 As shown, the crystal rod straightening device of this utility model embodiment includes: a conveying mechanism 1, a correction mechanism 2, a feeding mechanism 3, and a straightening mechanism 4. The conveying mechanism 1, the correction mechanism 2, the feeding mechanism 3, and the straightening mechanism 4 are all mounted on a worktable to ensure stable operation of each mechanism.
[0032] The conveying mechanism 1 includes a first slide rail 11 and a first pneumatic gripper 12, the first pneumatic gripper 12 being slidably mounted on the first slide rail 11 in a horizontal direction.
[0033] The calibration mechanism 2 is located below the first slide rail 11. The calibration mechanism 2 includes a first motor 21 and a rotating fixture 22. The rotating fixture 22 is connected to the drive end of the first motor 21 and is used to adjust the trimming angle of the crystal rod 5.
[0034] The feeding mechanism 3 is located below the first slide rail 11. The feeding mechanism 3 includes a second slide rail 31 and a second pneumatic gripper 32. The second pneumatic gripper 32 is slidably mounted on the second slide rail 31 in the vertical direction.
[0035] The straightening mechanism 4 is located on one side of the feed mechanism 3. The straightening mechanism 4 includes a motor base 41, a second motor 42 and a grinding wheel 43. The second motor 42 is mounted on the motor base 41, and the grinding wheel 43 is horizontally positioned above the motor base 41. The drive end of the second motor 42 is connected to the grinding wheel 43.
[0036] In this embodiment, the transport mechanism 1 is used to move the crystal rod 5 from the correction mechanism 2 to the feed mechanism 3, and the feed mechanism 3 is used to drive the crystal rod 5 to move vertically and be ground by the grinding wheel 43 to form a straight edge.
[0037] During operation, the crystal rod 5 with straight edges is identified under a microscope to determine the lattice direction, and the lattice direction is marked on the end face of the crystal rod 5. The transport mechanism 1 is activated, and the crystal rod 5 is clamped by the first pneumatic gripper 12 and moved along the first slide rail 11 to the correction mechanism 2 for release. The correction mechanism 2 is activated, and the crystal rod 5 on the rotating fixture 22 is rotated by the first motor 21 to adjust the crystal rod 5 to the required angle. The crystal rod 5 on the rotating fixture 22 is clamped by the first pneumatic gripper 12 and moved to the feed mechanism 3. The second pneumatic gripper 32 drives the crystal rod 5 to move vertically and be ground by the grinding wheel 43 to form a straight edge.
[0038] Based on the above structural setup, the trimming angle of the crystal rod can be adjusted by the correction mechanism 2. The conveying mechanism 1, correction mechanism 2, feeding mechanism 3 and trimming mechanism 4 work together to achieve automated trimming, which improves processing efficiency.
[0039] like Figure 1 and 6 As shown, in some embodiments, two sets of feeding mechanisms 6 are included. The feeding mechanism 6 is located below the first slide rail 11. The feeding mechanism 6 is used to mount multiple crystal rods 5, and the conveying mechanism 1 is used to move the crystal rods 5 from the feeding mechanism 6 to the correction mechanism 2. In this way, the conveying mechanism 1 can move along both sides horizontally to clamp the crystal rods 5, which facilitates the feeding of the crystal rods 5.
[0040] like Figure 1 and 6 As shown, in some embodiments, the loading mechanism 6 includes a third slide rail 61 and a loading fixture 62. The loading fixture 62 has multiple mounting slots 621. The loading fixture 62 is slidably mounted on the third slide rail 61 in a horizontal direction, and the moving direction of the loading fixture 62 is perpendicular to the moving direction of the first pneumatic gripper 12. In this way, the loading fixture 62 can hold multiple crystal rods 5, and the movement of the loading fixture 62 along the third slide rail 61 facilitates the first pneumatic gripper 12 of the conveying mechanism 1 to grasp the crystal rods 5.
[0041] In some embodiments, the first slide rail 11, the second slide rail 31, and the third slide rail 61 are all lead screw slide rails. Thus, using lead screw slide rails ensures precise movement. For example, a lead screw slide rail includes a motor, a coupling, a lead screw, and a slider. The motor drives the lead screw to rotate via the coupling, and the slider is mounted on the lead screw, thereby enabling the lead screw to drive the slider to move linearly. Each moving component is mounted on the slider for operation.
[0042] like Figure 2 As shown, in some embodiments, the conveying mechanism 1 includes two columns 13, which are respectively installed at both ends of the first slide rail 11. This provides space at the bottom of the first slide rail 11 for installing the correction mechanism 2, the feeding mechanism 3, and the straightening mechanism 4.
[0043] like Figure 2 As shown, in some embodiments, the handling mechanism 1 includes a dual-axis cylinder 14, which is slidably mounted on the first slide rail 11 in the horizontal direction. The output end of the dual-axis cylinder 14 is connected to the first pneumatic gripper 12, and the dual-axis cylinder 14 is used to drive the first pneumatic gripper 12 to move in the vertical direction. In this way, the first pneumatic gripper 12 can move in both the horizontal and vertical directions, which facilitates the handling of the crystal rod 5.
[0044] like Figure 2 As shown, in some embodiments, a camera 7 is included, which is mounted on the first slide rail 11 and is used to photograph the crystal rod 5. Thus, the camera 7 can acquire the rotation angle information of the crystal rod 5.
[0045] like Figure 3 As shown, in some embodiments, the correction mechanism 2 includes a rotating platform 23, and a first motor 21 is connected to a rotating fixture 22 via the rotating platform 23. The rotating fixture 22 rotates about the vertical direction. Specifically, the spindle of the first motor 21 drives the rotating platform 23 to rotate, and the rotating fixture 22 is mounted on the rotating platform 23, thereby causing the rotating fixture 22 to rotate.
[0046] like Figure 2 As shown, in some embodiments, the first pneumatic gripper 12 includes a first gripping cylinder 121 and a first gripper 122. The first gripping cylinder 121 is slidably mounted on the first slide rail 11 in a horizontal direction, and the first gripper 122 is mounted on the output end of the first gripping cylinder 121. Thus, the first gripping cylinder 121 drives the first gripper 122 to move closer together to clamp the crystal rod 5, and the first gripping cylinder 121 drives the first gripper 122 to move away from each other to release the crystal rod 5.
[0047] In some embodiments, the second pneumatic gripper 32 includes a second gripping cylinder 321 and a second gripper 322. The second gripping cylinder 321 is slidably mounted on the second slide rail 31 in a vertical direction, and the second gripper 322 is mounted on the output end of the second gripping cylinder 321. Thus, the second gripping cylinder 321 drives the second gripper 322 to move closer together to clamp the crystal rod 5, and the second gripping cylinder 321 drives the second gripper 322 to move away from each other to release the crystal rod 5.
[0048] 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.
