Description

Technical Field

[0001] This utility model relates to the field of crystal rod edge grinding technology, and in particular to a substrate crystal rod edge grinding device. Background Technology

[0002] Indium phosphide (InP) substrates, due to their excellent electron mobility and high breakdown electric field characteristics, have become an ideal choice for manufacturing high-frequency, high-power devices, enjoying a wide range of applications in radio frequency (RF) devices such as fiber optic communication, wireless transmission, and radio astronomy. Particularly in high-end applications such as satellites and radar, RF devices manufactured using InP substrates have demonstrated superior performance. These devices exhibit strong competitiveness in the RF front-ends of radar and communication systems and in wide-bandwidth analog / mixed-signal circuits, making them ideal for applications requiring high-speed data processing and high-precision wide-bandwidth A / D conversion.

[0003] Indium phosphide (IP)-based radio frequency (RF) devices, such as low-noise amplifiers, modules, and receivers, are widely used in satellite communications, millimeter-wave radar, and active and passive millimeter-wave imaging. Particularly at ultra-high bandwidth levels above 100 GHz, IPT-based RF devices have demonstrated significant advantages in wireless transmission for backhaul networks and point-to-point communication networks.

[0004] Despite the significant advantages of indium phosphide in high-performance radio frequency devices, current technological development focuses on improving manufacturing processes to further enhance production efficiency and reduce manufacturing costs. For example, the traditional method for chamfering indium phosphide substrate ingots is to use a single chamfer, which means that an ingot needs to be chamfered twice and requires multiple loading and unloading operations, resulting in low efficiency.

[0029] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0030] like Figure 1 and Figure 3 As shown, this utility model provides a substrate ingot edge grinding device, including a loading mechanism 1, a transfer mechanism 2, a chamfering mechanism 3, and an unloading mechanism 4. The loading mechanism 1 is located at the feeding end of the transfer mechanism 2 to transport the ingot 5 to the transfer mechanism 2, realizing automated loading, improving production efficiency, and reducing manual intervention. The transfer mechanism 2 is located at the feeding end of the unloading mechanism 4 to transport the processed ingot 5 to the unloading mechanism 4, completing the end operation of the automated production line. There are two chamfering mechanisms 3, which are arranged opposite to each other on both sides of the transfer mechanism 2, for simultaneously chamfering the two side edges of the ingot 5. The chamfering mechanism 3 includes a first drive assembly 31, a first drive member 32, a mounting plate 33, and a chamfering grinding wheel 34. The first drive assembly 31 is located on one side of the transfer mechanism 2 and is connected to the mounting plate 33 to drive the mounting plate 33 to move towards or away from another chamfering mechanism 3. The chamfering grinding wheel 34 is rotatably mounted on the side of the mounting plate 33 facing the transfer mechanism 2. The chamfering grinding wheel 34 is used to directly contact the edge of the crystal ingot 5 and grind its edge by high-speed rotation to form the required chamfer shape (such as a 45° chamfer). The first drive member 32 is mounted on the mounting plate 33 and connected to the chamfering grinding wheel 34 to drive the chamfering grinding wheel 34 to rotate, providing grinding power, effectively removing edge burrs and sharp angles of the crystal ingot 5, preventing edge chipping and cracking in the subsequent slicing process, and improving wafer yield.

[0031] Based on the above structure, in this embodiment, the crystal rod 5 is fed into the transfer mechanism 2 by the feeding mechanism 1. The transfer mechanism 2 transports the crystal rod 5 to the chamfering station. The chamfering grinding wheels 34 on both sides approach the crystal rod 5 under the push of the first driving component 31. The first driving component 32 is activated, driving the chamfering grinding wheels 34 to rotate at high speed. The chamfering grinding wheels 34 contact the edge of the crystal rod 5 to perform chamfering grinding. After the processing is completed, the chamfering grinding wheels 34 retract, and the transfer mechanism 2 sends the crystal rod 5 to the unloading mechanism 4. The unloading mechanism 4 outputs the finished crystal rod 5, completing one processing cycle.

[0032] This embodiment integrates the entire process of feeding, conveying, processing, and unloading, reducing manual operations and improving production efficiency. It also employs a symmetrical double-sided chamfering method to ensure consistent chamfering at both ends of the crystal ingot 5, avoiding stress deformation caused by unilateral processing. Furthermore, the first drive component 31 can adjust the distance between the chamfering grinding wheel 34 and the crystal ingot 5, making it suitable for crystal ingots 5 of different lengths and offering high flexibility. It should be noted that the first drive component 32 in this embodiment is a motor.

[0033] like Figure 3 As shown, the first drive assembly 31 includes a second drive component 311 and a base 312. The second drive component 311 is mounted on the mounting platform via the base 312, and the second drive component 311 is connected to the mounting plate 33.

[0034] Based on the above structure, the second driving component 311 is detachably mounted on the mounting platform via the base 312 to ensure its stable position. The moving end of the second driving component 311 is connected to the mounting plate 33. When chamfering is required, the second driving component 311 is activated, pushing the mounting plate 33 forward. The mounting plate 33 drives the first driving component 32 and the chamfering wheel 34 to move together towards the crystal rod 5. The chamfering wheel 34 contacts the end of the crystal rod 5 and rotates at high speed under the drive of the first driving component 32 to chamfer the edge of the crystal rod 5. After the operation is completed, the second driving component 311 moves in the opposite direction (i.e., retracts), pulling the mounting plate 33, the first driving component 32, and the chamfering wheel 34 back to their original positions, thus separating the chamfering wheel 34 from the crystal rod 5 and avoiding interference with subsequent processes or damage.

[0035] It should be noted that the second driving component 311 in this embodiment is a slide cylinder, and the mounting platform can be a bracket, a worktable or a machine tool surface, without any particular limitation. The mounting platform is intended to provide a mounting base for the chamfering mechanism 3 to facilitate the stability of the chamfering mechanism 3 during processing.

[0036] like Figure 1 , Figure 2 and Figure 4As shown, the transfer mechanism 2 includes a support frame 21, a moving fixture 22, a second drive assembly 23, and a third drive assembly 24. The support frame 21 serves as the skeleton of the transfer mechanism 2, providing support and positioning. It is located between the loading mechanism 1 and the unloading mechanism 4, allowing the crystal rod 5 to be transported from the loading mechanism 1 to the chamfering station and then to the unloading mechanism 4. The support frame 21 has a displacement channel 211 and multiple placement positions 212 arranged on both sides of the displacement channel 211. These placement positions 212 are used to support the crystal rod 5. The multiple placement positions 212 are spaced apart along the extension direction of the displacement channel 211. The second drive assembly 23 is installed below the displacement channel 211 and connected to the third drive assembly 24 to drive the third drive assembly 24 to move up and down. The moving fixture 22 is used to carry and fix the crystal rod 5 to be transported. It is located in the displacement channel 211, and the third drive assembly 24 is connected to the moving fixture 22 to drive the moving fixture 22 to reciprocate within the displacement channel 211, realizing the transfer of the crystal rod 5 between different placement positions.

[0037] Based on the above structure, after the feeding mechanism 1 places the crystal rod 5 on the moving fixture 22, the second driving component 23 drives the moving fixture 22 to rise until the crystal rod 5 is separated from the support frame 21. The third driving component 24 drives the crystal rod 5 to move along the extension direction of the displacement channel 211 to move forward one placement position 212. At this time, the second driving component 23 drives the moving fixture 22 to descend until the crystal rod 5 lands on the placement position 212 on the support frame 21. This process is repeated to realize the displacement of the crystal rod 5 between the placement positions 212 on the support frame 21, so as to transport the crystal rod 5 to the chamfering station and the unloading end. This allows for synchronous operation and improves production efficiency.

[0038] Furthermore, two chamfering grinding wheels 34 are disposed on both sides of the same placement position 212, and are correspondingly disposed to the placement position 212. In this embodiment, a chamfering grinding wheel 34 is installed on the left and right sides of a specific placement position 212 (i.e., the chamfering station), and the two chamfering grinding wheels 34 face the placement position 212. When the crystal ingot 5 is delivered to this position, the chamfering grinding wheels 34 can simultaneously chamfer the crystal ingot 5 from both ends, realizing integrated processing capabilities in the handling process, eliminating the need for a separate chamfering mechanism 3, and the two chamfering grinding wheels 34 work simultaneously from both ends, improving processing efficiency and symmetry (such as edge deburring, corner grinding, etc.).

[0039] Furthermore, the support frame 21 includes two support plates 213, which are spaced apart to define a displacement channel 211. Each support plate 213 has multiple first placement slots 2131, and the first placement slots 2131 on the two support plates 213 are arranged in a one-to-one correspondence to form a placement position 212. In this embodiment, the support frame 21 is composed of two symmetrically arranged support plates 213, which is easy to process and assemble. In addition, each placement position 212 is composed of a pair of first placement slots 2131. The multiple first placement slots 2131 are distributed along the displacement channel 211 to realize the layout of multiple equidistant placement positions 212. The placement positions 212 formed by the first placement slots 2131 provide a positioning reference for the crystal rod 5, ensuring its accurate position during transportation.

[0040] Furthermore, the moving fixture 22 has multiple second placement slots spaced apart along its length. These second placement slots are used to hold the crystal ingots 5. The interval between two second placement slots matches the interval between two placement positions 212, so that when the moving fixture 22 moves one step, each second placement slot is aligned with the first placement slot 2131 at the next position. In this embodiment, the moving fixture 22 has three second placement slots, which can transport three workpieces at a time, moving one placement position 212 at a time, to achieve step-by-step assembly line operation and batch transfer of crystal ingots 5.

[0041] It should be noted that the number of the second placement slots in this embodiment can be adjusted as needed, and no particular limitation is made here.

[0042] like Figure 5 As shown, the second drive assembly 23 includes a third drive member 231 and a rising plate 232. The rising plate 232 is a flat plate structure used to support the third drive assembly 24. Two third drive members 231 are disposed at both ends of the rising plate 232 to drive the rising plate 232 to rise and fall along the height direction of the support frame 21. The moving fixture 22 changes its height through the third drive member 231 so that the crystal rod 5 can be removed from the support frame 21 for subsequent movement to the next placement position 212.

[0043] Based on the above structure, in this embodiment, two third driving components 231 drive the rising plate 232 to move up and down along the height direction of the support frame 21, thereby driving the movable fixture 22 placed on it to rise or fall. When rising, the crystal rod 5 is driven to detach from the support frame 21, so that the crystal rod 5 can be easily moved from the current position to the next placement position 212; when falling, the crystal rod 5 is driven to be installed on the corresponding placement position 212.

[0044] It should be noted that the third driving component 231 in this embodiment is a cylinder, and the third driving component is mounted on the mounting platform via a mounting bracket or mounting plate or other mounting structure. The mounting platform can be a bracket, a worktable, or a machine tool surface, and is not particularly limited here. The purpose of the mounting platform is to provide a mounting base for the third driving component to facilitate the stability of the third driving component during processing. It can be understood that the mounting platform can be a different horizontal plane with the same structure as the previous mounting platform, or it can be a different mounting platform.

[0045] Furthermore, the third drive assembly 24 includes a mounting base 241, a slider, a fourth drive member 242, a coupling 243, a lead screw 244, and a connecting plate 245. The mounting base 241 serves as the basic support structure for the entire third drive assembly 24 and is used to fix other components. It is mounted on the side of the rising plate 232 facing the displacement channel 211. The fourth drive member 242 and the lead screw 244 are mounted on the mounting base 241. The fourth drive member 242 and the lead screw 244 are connected by the coupling 243 so that the lead screw 244 can be driven to rotate by the fourth drive member 242. The slider is mounted on the lead screw 244 so that it can move axially as the lead screw 244 rotates. The moving fixture 22 is connected to the slider through the connecting plate 245.

[0046] Based on the above structure, after the fourth drive component 242 is started, its output shaft rotates and transmits torque to the lead screw 244 through the coupling 243, so that the lead screw 244 rotates synchronously. The slider is installed on the lead screw 244. As the lead screw 244 rotates, the slider generates linear reciprocating motion according to the thread lead. The slider drives the moving fixture 22 to move together through the connecting plate 245, so as to realize the linear displacement of the moving fixture 22 in the horizontal direction.

[0047] It should be noted that the fourth driving component 242 in this embodiment is a motor.

[0048] like Figure 1 and Figure 6As shown, the feeding mechanism 1 includes a first support 11, a first linear module 12, a fifth drive member 13, a first gripper assembly 14, and a feeding fixture 15. The feeding fixture 15 has multiple first grooves for placing crystal rods 5, each first groove can accommodate one crystal rod 5, serving to position, prevent rolling, and arrange neatly. The feeding fixture 15 is located at the feeding end of the transfer mechanism 2, allowing the crystal rods 5 to be fed from the feeding fixture 15 onto the transfer mechanism 2. The first support 11 is disposed on one side of the feeding fixture 15 to serve as a support frame for the first gripper assembly 14. The first linear module 12 is mounted on the first support 11, and the fifth drive member 13 is mounted on the first linear module 12 to move along the length of the first support 11. The fifth drive member 13 is connected to the first gripper assembly 14 to drive the first gripper assembly 14 to rise and fall. The first gripper assembly 14 is located above the feeding fixture 15 so that the first gripper assembly 14 can approach the crystal rods 5 from above, facilitating the gripping of the crystal rods 5 placed in the first grooves.

[0049] Based on the above structure, the operator or the preceding process places multiple crystal rods 5 into the first groove of the loading fixture 15. The first linear module 12 drives the fifth drive component 13 and the first gripper assembly 14 to move directly above the target crystal rod 5. The fifth drive component 13 drives the first gripper assembly 14 to descend, and the first gripper assembly 14 grabs the crystal rod 5. Subsequently, the first gripper assembly 14 rises and is then moved by the first linear module 12 above the transfer mechanism 2. The first gripper assembly 14 descends and releases the crystal rod 5, placing it into the transfer mechanism 2. Then, the first gripper assembly 14 rises and is moved by the first linear module 12 to the corresponding first groove for the next transfer. This embodiment realizes the automatic transfer of crystal rods 5 from the loading fixture 15 to the automated production line, reducing manual intervention. Multiple first grooves can hold multiple crystal rods 5 at once, improving loading efficiency and enabling continuous, cyclical loading to meet the needs of continuous production.

[0050] It should be noted that the fifth driving component 13 in this embodiment is a slide cylinder, and the first linear module 12 is a conventional linear motion module, which is not particularly limited here. In addition, the first gripper assembly 14 includes a gripping cylinder and two grippers, and the gripping cylinder drives the two grippers to open or grip.

[0051] Understandably, the loading fixture 15 is mounted on a mounting platform, which can be a bracket, a worktable, or a machine tool surface, without particular limitation. The mounting platform is designed to provide a mounting base for the loading fixture 15 to facilitate its stability. Understandably, the mounting platform can be a different horizontal plane with the same structure as the previous mounting platform, or it can be a different mounting platform.

[0052] like Figure 1 and Figure 7As shown, the unloading mechanism 4 includes a second support 41, a second linear module 42, a sixth drive component 43, a second gripper assembly 44, and an unloading fixture 45. The unloading fixture 45 has multiple second grooves for placing crystal rods 5, each second groove can accommodate one crystal rod 5, serving to position, prevent rolling, and arrange neatly. The unloading fixture 45 is located at the discharge end of the transfer mechanism 2, allowing the crystal rods 5 to be fed from the transfer mechanism 2 onto the unloading fixture 45. The second support 41 is disposed on one side of the unloading fixture 45. The second linear module 42 is mounted on the second bracket 41 as a support frame for the second gripper assembly 44. The sixth drive member 43 is mounted on the second linear module 42 to move along the length direction of the second bracket 41. The sixth drive member 43 is connected to the second gripper assembly 44 to drive the second gripper assembly 44 to rise and fall. The second gripper assembly 44 is located above the unloading fixture 45 so that the second gripper assembly 44 can approach the unloading fixture 45 from above and place the gripped crystal rod 5 into the second groove.

[0053] Based on the above structure, the second linear module 42 drives the sixth driving component 43 and the second gripper assembly 44 to move directly above the target crystal ingot 5. The sixth driving component 43 drives the second gripper assembly 44 to descend, and the second gripper assembly 44 grips the crystal ingot 5 located on the transfer mechanism 2 and processed by the chamfering grinding wheel 34. Subsequently, the second gripper assembly 44 rises and is then moved by the second linear module 42 to above the unloading fixture 45. The second gripper assembly 44 descends and releases the crystal ingot 5, placing it into the unloading fixture 45. Then, the second gripper assembly 44 rises and is moved by the second linear module 42 to above the corresponding crystal ingot 5 for the next transfer. This embodiment realizes the automatic transfer of the crystal ingot 5 from the transfer mechanism 2 to the unloading fixture 45, reducing manual intervention. Multiple second grooves can hold multiple crystal ingots 5 at one time, improving unloading efficiency and enabling continuous and cyclic unloading to meet the needs of continuous production.

[0054] It should be noted that the sixth driving component 43 in this embodiment is a slide cylinder, and the second linear module 42 is a conventional linear motion module, which is not particularly limited here. In addition, the second gripper assembly 44 includes a gripping cylinder and two grippers, and the gripping cylinder drives the two grippers to open or grip.

[0055] Understandably, the unloading fixture 45 is mounted on a mounting platform, which can be a bracket, a worktable, or a machine tool surface, without particular limitation. The mounting platform is designed to provide a mounting base for the unloading fixture 45 to facilitate its stability. Understandably, the mounting platform can be a different horizontal plane with the same structure as the previous mounting platform, or it can be a different mounting platform.

[0056] The working principle is as follows:

[0057] At the feeding mechanism 1, a corresponding number of crystal rods 5 are manually loaded into the feeding fixture 15. The first linear module 12 at the feeding mechanism 1 drives the fifth driving component 13 and the first gripper assembly 14 to move above the corresponding crystal rod 5. At this time, the fifth driving component 13 drives the first gripper assembly 14 to move down to the corresponding crystal rod 5. The first gripper assembly 14 clamps the crystal rod 5. The fifth driving component 13 drives the first gripper assembly 14 to move up until the crystal rod 5 is released from the feeding fixture 15. The first linear module 12 drives the first gripper assembly 14 to move above the support plate 213 at the transfer mechanism 2. The fifth driving component 13 drives the first gripper assembly 14 to move down to the second placement slot of the moving fixture 22 (that is, the corresponding placement position 212). The first gripper assembly 14 releases the crystal rod 5 and rises to detach from the crystal rod 5. At this time, the third drive member 231 moves upward, causing the moving fixture 22 and the crystal rod 5 to rise until the crystal rod 5 is separated from the support plate 213. The fourth drive member 242 drives the moving fixture 22 forward, so that the crystal rod 5 moves forward one placement position 212. Then the third drive member 231 descends, causing the moving fixture 22 and the crystal rod 5 to fall back to the placement position 212 on the support plate 213. When the crystal rod 5 is transported to the chamfering processing position, the second drive member 311 rotates, causing the chamfering grinding wheel 34 to rotate. The second drive member 311 moves forward, causing the chamfering grinding wheel 34 to move toward the crystal rod 5 to perform the chamfering operation. After the operation is completed, the second drive member 311 retracts, causing the chamfering grinding wheel 34 to retract as well. Then, the second linear module 42 drives the second gripper assembly 44 to move above the corresponding crystal rod 5. The sixth drive unit 43 drives the second gripper assembly 44 to move down to the corresponding crystal rod 5. The second gripper assembly 44 clamps the crystal rod 5. The sixth drive unit 43 drives the second gripper assembly 44 to move up until the crystal rod 5 is disengaged from the moving fixture 22. The second linear module 42 drives the second gripper assembly 44 to move above the unloading fixture 45. The sixth drive unit 43 drives the first gripper assembly 14 to move down to the second groove. The second gripper assembly 44 releases the crystal rod 5 and rises to disengage from the crystal rod 5. The operation is completed.

[0058] Understandably, the above-described process is for a single crystal ingot 5. This process can simultaneously transport multiple crystal ingots 5, and after the chamfering wheel 34 completes the chamfering of one crystal ingot 5, the next crystal ingot 5 is directly transported and chamfered, forming a continuous assembly line operation. This structure allows for centralized material loading to reduce manual loading multiple times, improving work efficiency. At the same time, the assembly line layout saves space and floor space.

[0059] In summary, this utility model embodiment provides a substrate crystal rod edge grinding device that integrates the entire process of feeding, conveying, processing, and unloading, reducing manual operation and improving production efficiency. It adopts a symmetrical double-sided chamfering method to ensure the consistency of the chamfers at both ends of the crystal rod 5, avoiding stress deformation caused by single-sided processing. At the same time, the first driving component 31 can adjust the distance between the chamfering grinding wheel 34 and the crystal rod 5, making it suitable for crystal rods 5 of different lengths and highly flexible.

[0060] 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.
