Description

Technical Field

[0001] The present application relates to the field of grinding technology, and in particular to a grinding headstock and a grinding machine tool. Background Art

[0002] When processing crystal materials, the crystal rod needs to be cut into multiple cylindrical blocks, and then the blocks are ground to form the wafers required for subsequent production. When grinding the blocks, the crystal orientation needs to be measured, and then the crystal grinding is performed based on the results of the crystal orientation measurement. Crystal grinding includes grinding from the end face of the crystal and grinding from the circumference of the crystal.

[0003] Among them, the end face of the crystal needs to be exposed during end face grinding, and at this time it is necessary to clamp and fix it from the circumferential surface of the crystal; the circumferential surface of the crystal needs to be exposed during circumferential surface grinding, and at this time it is necessary to clamp it from both ends of the crystal. This results in the need to replace different grinding equipment when grinding at different positions to meet the corresponding clamping and fixing methods. However, when replacing different equipment, re-positioning, fixing, etc. are required, and there will be assembly errors between different equipment, which not only makes the processing accuracy easily damaged, but also the processing efficiency is low. Even if the related technology uses viscose, wax and other fixing methods to eliminate the assembly errors between different equipment, it will increase the wax sticking and dewaxing environment, thereby increasing the processing time.

[0027] Unless otherwise defined, all technical and scientific terms used in the specification of this application have the same meaning as those commonly understood by those skilled in the art of the technical field of this application. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0028] See also Figures 1 to 4 In an optional embodiment, the grinding head frame 100 includes a clamping jaw assembly 30, a support table 20 and a driving assembly 10. The driving assembly 10 includes a power shaft 11 having a first axis, and the support table 20 is connected to the power shaft 11 and can rotate around the first axis under the action of the power shaft 11. The clamping jaw assembly 30 is connected to the driving assembly 10, and the clamping jaw assembly 30 includes at least two clamping arms 31 arranged at intervals around the first axis, and each clamping arm 31 is jointly enclosed to form a clamping space. Each clamping arm 31 can move closer to or away from the support table 20, and each clamping arm 31 can move relative to the support table 20 along the first axis direction so that the support table 20 is accommodated in the clamping space or outside the clamping space. Among them, the direction of the first axis can be the X-axis direction, hereinafter referred to as the first axial direction or the X-axial direction.

[0029] In actual use, the crystal rod is first cut into a plurality of cylindrical crystal blocks, and then the cylindrical crystal blocks are ground to form the wafers required in the subsequent process. The grinding head frame 100 provided in this embodiment is used to fix the cut cylindrical crystal blocks to achieve grinding. Therefore, the crystals referred to below all refer to cylindrical crystal blocks.

[0030] It can be understood that, since each clamping arm 31 can move relative to the support table 20 along the first axis direction, the position of the support table 20 relative to each clamping arm 31 can be adjusted. When each clamping arm 31 moves to the point where the support table 20 is outside the clamping space, the support table 20 can cooperate with the grinding tailstock 200 to clamp at both ends of the crystal in the thickness direction, and the circumferential surface of the crystal can be exposed at this time, which can be used for circumferential surface grinding; and, precisely because of the movement of each clamping arm 31, no interference is caused to the cooperation of the grinding tailstock 200, thereby ensuring the clamping stability. When each clamping arm 31 moves to the point where the support table 20 is located in the clamping space, at least two clamping arms 31 can cooperate with each other to clamp at the circumferential surface of the crystal, causing one end face of the crystal along its own thickness direction to be exposed, which can be used for end face grinding; and, at this time, the crystal can also be abutted against the support table 20 to limit the clamping position of the crystal along its own thickness direction, ensuring that a portion of the crystal can protrude relative to the clamping arm 31, thereby avoiding interference with the grinding operation.

[0031] In summary, the grinding head frame 100 provided in this embodiment is not only used to fix the crystal during end face grinding, but also can be used to fix the crystal during circumferential surface grinding. Therefore, there is no need to replace different equipment at different grinding positions, and only the position of each clamping arm 31 relative to the support table 20 needs to be adjusted. Such a setting not only reduces the time consumed in the circulation between different equipment and the time consumed in the loading and unloading processes involved in the circulation process, and improves the processing efficiency of the crystal; and, it avoids assembly errors when clamping different equipment as much as possible, and improves the processing accuracy. In addition, compared with the use of wax to fix the crystal in the related art, the grinding head frame 100 provided in this embodiment is free from the wax sticking and dewaxing links, which greatly shortens the processing time.

[0032] Wherein, the drive assembly 10 can adopt a motor, and the power shaft 11 can be the motor shaft of the motor, or it can be a shaft connected to the motor shaft for transmitting power and bearing. Alternatively, the drive assembly 10 also includes a motor, and the motor shaft of the motor is connected to the power shaft 11, such as a key connection, or the power shaft 11 is connected to the motor shaft through a transmission structure such as a transmission belt group. As long as it can realize the rotation of the power shaft 11, an example is given here. The drive assembly 10 also includes an assembly shell 12 installed on the outside of the power shaft 11, and the clamping jaw assembly 30 can be connected to the assembly shell 12 to ensure that the clamping jaw assembly 30 is stable during the clamping process. Of course, the clamping jaw assembly 30 can also be connected to the power shaft 11 to rotate under the action of the power shaft 11 and cooperate with the grinding wheel for grinding.

[0033] Please continue reading Figures 1 to 4 Exemplarily, the clamping assembly 30 also includes a clamping seat 32, and the clamping seat 32 is sleeved on the power shaft 11, and the power shaft 11 can rotate around the first axis relative to the clamping seat 32 to drive the support table 20 to rotate synchronously. Such a configuration can ensure that the clamping assembly 30 is installed stably and improve the clamping and fixing effect. Each clamping arm 31 is movably connected to the clamping seat 32, so that each clamping arm 31 can move closer to or away from the support table 20 to achieve clamping and loosening of the crystal; at the same time, each clamping arm 31 can move relative to the clamping seat 32 along the first axis to adjust the position relative to the support table 20 along the first axis, so as to achieve switching of different fixing methods, thereby meeting various operation requirements.

[0034] Further, the clamping jaw seat 32 includes a first seat body 321, a second seat body 323 and a linear drive member 322. The first seat body 321 and the second seat body 323 are both sleeved on the outer side of the power shaft 11 and arranged at intervals along the first axis direction. The first seat body 321 is connected to the assembly housing 12 in the drive assembly 10 to ensure the stable assembly of the clamping jaw assembly 30, and the power shaft 11 rotates around the X-axis relative to the first seat body 321 and the second seat body 323. The second seat body 323 is movably connected to each clamping arm 31 to meet the needs of each clamping arm 31 to move closer to or farther from the support platform 20 to achieve clamping and loosening. The linear drive member 322 is connected between the first seat body 321 and the second seat body 323, and is used to drive the second seat body 323 to move along the first axis direction. The second seat body 323 drives each clamping arm 31 to move synchronously, thereby meeting the needs of each clamping arm 31 to move along the X-axis direction, so as to adjust the position of each clamping arm 31 relative to the support platform 20 and meet different fixing methods.

[0035] Each clamping arm 31 can be rotatably connected to the second seat body 323, for example, by using a hinge seat and a hinge structure to be hinged to the second seat body 323. Each clamping arm 31 rotates closer to the first axis to clamp, and rotates away from the first axis to release. Alternatively, each clamping arm 31 can also be slidably connected to the second seat body 323, for example, by using a slide rail and a slide groove, each clamping arm 31 can move along the radial direction of the power shaft 11, move radially inward to clamp, and move radially outward to release.

[0036] In some specific embodiments, the linear drive member 322 may be an oil cylinder, a gas cylinder or an electric push rod. At the same time, the number of the linear drive members 322 is at least two, and they are arranged at intervals around the first axis to ensure stable force. For example, there are two linear drive members 322, and they are arranged at an interval of 180 degrees.

[0037] like Figure 1 and Figure 3 As shown, further, the first seat body 321 may be provided with an assembly cavity 3210, and each linear drive member 322 and the second seat body 323 are accommodated in the assembly cavity 3210. The clamping jaw seat 32 also includes a first end plate 324, which is connected to the open portion of the assembly cavity 3210 to cooperate with the first seat body 321 to form a protection for the linear drive member 322 and the second seat body 323; and the first end plate 324 can also be used as a movement limiter for the second seat body 323 to prevent the clamping arm 31 from extending too much. The linear drive member 322 includes a cylinder body and a first piston rod, the cylinder body is connected to the first seat body 321, and the first piston rod is connected to the second seat body 323. The extension and retraction of the first piston rod are used to realize the linear movement of each clamping arm 31.

[0038] Alternatively, each clamping arm 31 may be provided with a corresponding linear drive member 322. Each clamping arm 31 is connected to the first piston rod of the corresponding linear drive member 322, and a mounting block is provided between the first piston rod and the corresponding clamping arm 31, and the clamping arm 31 is rotationally connected or slidably connected to the corresponding mounting block to achieve linear motion, clamping, and loosening of each clamping arm 31. Alternatively, each clamping arm 31 corresponds to a second seat body 323, and the number of the second seat bodies 323 is the same as the number of the clamping arms 31, and they are arranged at intervals around the X-axis, and a linear drive member 322 is connected between each second seat body 323 and the first seat body 321.

[0039] The first end plate 324 is configured with an assembly hole for the movement of the clamping arm 31 or the second seat body 323 to avoid interference with the adjustment of each clamping arm 31 relative to the support platform along the radial direction of the power shaft 11 .

[0040] In another specific embodiment, the number of the clamping arms 31 is two and arranged at 180 degrees intervals; it can also be three and arranged at 120 degrees intervals; or even four and arranged at 90 degrees intervals. The number of the clamping arms 31 should not be too large, which will not only waste resources and make assembly inconvenient, but also may cause crystal wear due to the larger clamping range with the crystal; nor should it be too small, which will affect the clamping stability.

[0041] like Figure 1 and Figure 4 As shown, illustratively, the support table 20 is constructed with a plurality of adsorption holes 21 arranged at intervals and air passages connected to each adsorption hole 21. The grinding head frame 100 also includes an exhaust assembly, which is connected to the air passage so that negative pressure can be formed at each adsorption hole 21, and then the crystal is fixed by adsorption using the negative pressure. Compared with the use of wax to fix the crystal in the related art, the grinding head frame 100 provided in this embodiment is free from the wax sticking and dewaxing links, which greatly shortens the processing time; and, such a setting can further improve the fixing effect of the crystal.

[0042] When the support table 20 cooperates with the clamping jaw assembly 30 to achieve crystal fixation, the adsorption effect on the crystal can improve the stability of the crystal when loading and unloading relative to the clamping jaw assembly 30 and prevent it from detaching. When the support table 20 cooperates with the grinding tailstock 200 to achieve crystal fixation, the adsorption effect on the crystal can minimize the radial movement caused by the grinding force during the grinding process. At the same time, when orienting, each clamping arm 31 moves to move the support table 20 out of the clamping space, and the support table 20 adsorbs and fixes the crystal so that the end face and circumferential surface of the crystal are exposed, which can be used for end face orientation and circumferential surface orientation of the crystal to avoid directional interference caused by the clamping jaw assembly 30.

[0043] It should be added that the orientation mentioned in this application refers to the measurement of the crystal orientation. Therefore, end face orientation is the measurement of the crystal end face orientation, and circumferential face orientation is the measurement of the crystal circumferential face orientation.

[0044] like Figure 1 and Figure 3 As shown, in actual use, the air extraction component includes a pneumatic source and an air pipe, and the air pipe is connected between the pneumatic source and the airway. Since the support platform 20 is connected to the end face of the power shaft 11, the power shaft 11 is configured with a through hole 1101 that penetrates along the first axis direction, and the air pipe can be penetrated in the through hole 1101 to ensure that the pneumatic source can be set at the end of the drive component 10 away from the support platform 20, and is not connected to the drive component 10, thereby reducing the load of the drive component 10 and improving the rotation stability. In addition, the through hole 1101 of the power shaft 11 is arranged to facilitate the installation and storage of the air pipe, and reduce the interference between the rotation and the air pipe assembly.

[0045] Please continue reading Figures 1 to 4 Optionally, the grinding head frame 100 also includes a turntable 40 and a mounting seat 50 mounted on the turntable 40. The turntable 40 has a second axis, and the mounting seat 50 can rotate around the second axis under the action of the turntable 40. The second axis is set at an angle to the first axis. Among them, take the Z-axis direction as an example. The drive assembly 10 is mounted on the mounting seat 50, and the clamping jaw assembly 30 can also be connected to the mounting seat 50. With such a setting, the angle adjustment of the mounting seat 50 can be achieved by utilizing the setting of the turntable 40, and then the installation angle of the clamping jaw assembly 30 and the support table 20 relative to other structures can be adjusted.

[0046] For example, when end face grinding is required, it can be rotated to a position facing the end face grinding mechanism; when circumferential surface grinding is required, it needs to be rotated to a position facing the grinding tailstock 200, so as to facilitate the cooperation with the grinding tailstock 200 to clamp the crystal. Therefore, the setting of the turntable 40 facilitates the rotation of the grinding headstock 100 to different positions to achieve adjustment of different workstations. The turntable 40 is driven by a motor and includes a turntable and a turntable shaft, which is rotatably connected to the turntable to rotate around a second axis; and the turntable shaft is connected to a turntable to connect to the support portion 52 of the mounting seat 50.

[0047] Further, the mounting seat 50 includes a sleeve portion 51 and a support portion 52. The support portion 52 is mounted on the turntable 40, and the sleeve portion 51 is connected to one end of the support portion 52 away from the turntable 40 along the second axis direction. The sleeve portion 51 is configured with a barrel cavity 5101 whose axis is along the first axis direction, the drive assembly 10 is mounted in the barrel cavity 5101, and partially extends out of the barrel cavity 5101 to connect to the support table 20, and the clamping jaw assembly 30 is connected to the end of the sleeve portion 51 facing the support table 20. It can be understood that the setting of the support portion 52 can raise the installation position of the drive assembly 10, the clamping jaw assembly 30 and the support table 20 to ensure that there is sufficient space under the crystal. The support portion 52 can be solidly set to ensure structural strength, thereby improving the support effect. The setting of the sleeve portion 51 facilitates the assembly of the drive assembly 10 relative to the mounting seat 50 and protects the drive assembly 10. Second end plates 53 may be provided at both ends of the sleeve portion 51 along the X-axis direction to provide protection. The clamping jaw seat 32 in the clamping jaw assembly 30 may be connected to the second end plate 53 at one end of the sleeve portion 51 facing the support platform 20 .

[0048] See also Figure 4 As shown, in another embodiment of the present application, a grinding machine tool is also provided, including a grinding tailstock 200 and the above-mentioned grinding headstock 100. The grinding tailstock 200 and the grinding headstock 100 are arranged at intervals. The grinding tailstock 200 includes a pressure head 210, and the pressure head 210 can cooperate with the support table 20 to clamp the workpiece to be processed (i.e., the crystal). At this time, the grinding headstock 100 can also use the turntable 40 to rotate relative to the grinding tailstock 200 to rotate the jaw assembly 30 and the support table 20 to other positions for orientation or end surface grinding, etc.

[0049] In actual use, the grinding headstock 100 has a first position and a second position. The grinding machine also includes a first grinding mechanism and a second grinding mechanism, which are arranged at intervals and are arranged at intervals relative to the grinding headstock 100. In the first position, the grinding headstock 100 and the grinding tailstock 200 are arranged oppositely and at intervals along the first axis direction, which is convenient for clamping the crystal from both ends of the crystal in the thickness direction. The first grinding mechanism is used to grind the outer peripheral surface of the workpiece to be processed to achieve circular surface grinding. In the second position, the grinding headstock 100 and the second grinding mechanism are arranged oppositely and at intervals along the first axis direction. The second grinding mechanism is used to grind the end face of the workpiece to be processed to achieve end face grinding.

[0050] In this way, the setting of the turntable 40 can be used to make the grinding head frame 100 rotate between different structures, and then the grinding machine can be used to achieve circular surface grinding and end surface grinding, without the need to specially set up corresponding grinding mechanisms for different grinding positions, which not only simplifies the structure but also improves the grinding efficiency.

[0051] Furthermore, the grinding machine also includes a crystal orientation meter for measuring the crystal orientation.

[0052] Taking the top view of the grinding machine as an example, the grinding head frame 100 has left and right sides and upper and lower sides. At this time, the grinding tailstock 200 can be arranged on the right side of the grinding head frame 100, the first grinding mechanism can be arranged on the lower side of the grinding head frame 100, and the second grinding mechanism can be arranged on the left side of the grinding head frame 100. In this way, the grinding head frame 100 rotates under the action of the turntable 40 until the support table 20 and the clamping jaw assembly 30 face the left side. At this time, the clamping jaw assembly 30 can be used to clamp the circumferential surface of the crystal for end face grinding. When the grinding head frame 100 rotates under the action of the turntable 40 until the support table 20 and the clamping jaw assembly 30 face the right side, the grinding tailstock 200 can be used to cooperate with the support table 20 to clamp on both sides of the crystal thickness for circumferential surface grinding.

[0053] Of course, the specific operation methods include but are not limited to the above, which are only given as examples here.

[0054] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
