Description

Technical Field

[0001] The utility model relates to the technical field of semiconductor production equipment, in particular to a stick gluing machine. Background Art

[0002] After tumbling, the surface of the ingot is provided with a notch, cut along a fixed crystal orientation. This notch is typically located at the outer edge of the ingot and extends axially through the ingot. Qualified ingots are then cut into wafers. The notch serves as a crucial guide for positioning during ingot cutting and subsequent wafer processing and testing.

[0003] The crystal ingot cutting process includes: first, the crystal ingot is placed on the roller of the ingot bonding machine and the notch of the crystal ingot is at the zero position, then the crystal orientation of the crystal ingot is measured, and then the roller is used to drive the crystal ingot to rotate a predetermined angle so that the notch reaches the bonding position, and then the crystal ingot is bonded to the resin plate, and the resin plate is fixed to the crystal support of the ingot bonding machine. Finally, the crystal ingot is cut by the cooperation of the resin plate and the wire cutting machine.

[0004] Among them, the step of using a roller to rotate the crystal ingot to a predetermined angle is very important. In the prior art, suction cup encoders or roller coaxial encoders are generally used to measure the rotation angle of the crystal ingot. The measurement accuracy of the suction cup encoder is affected by factors such as the coaxiality of the suction cup and the crystal ingot, the cleanliness of the crystal ingot end face, the smoothness of the crystal ingot end face, and the true roundness of the crystal ingot; the measurement accuracy of the roller coaxial encoder is affected by factors such as the cleanliness of the crystal ingot surface, physical defects on the crystal ingot surface, the true roundness of the crystal ingot, and the cleanliness of the roller surface. In practice, the measurement accuracy of suction cup encoders and roller coaxial encoders is approximately ±1°. In other words, the prior art measurement of the crystal ingot rotation angle is inaccurate, resulting in a large deviation between the actual position of the notch on the crystal ingot and the bonding position after the crystal ingot is rotated.

[0005] The utility model aims to provide a rod bonding machine, aiming to improve the accuracy of angle measurement during crystal rod rotation, thereby improving the quality of wafers obtained by subsequent slicing.

[0022] The aforementioned stick gluing machine includes a frame, a roller, and a rotation angle detection mechanism; the roller is rotatably mounted on the frame; the rotation angle detection mechanism includes a mounting frame, a base, and an angle detection element; the mounting frame is connected to the frame, the base is rotatably mounted on the mounting frame, and can be at least partially positioned at one axial end of the roller, the rotation axis of the base extending along the axial direction of the roller, and the base is further provided with an alignment portion; the angle detection element is configured to detect the rotation angle of the base. When the stick gluing machine is in use, the roller is used to support the crystal ingot and drive the crystal ingot to rotate. The rotation angle detection mechanism is used to detect whether the rotation angle of the crystal ingot is a predetermined angle, wherein the radius of the crystal ingot is equivalent to the distance from the alignment portion to the rotation axis of the base. The working process of the stick bonding machine is as follows: with the notch of the crystal ingot in the zero position, the alignment portion on the base is aligned with the notch, at which point the base's rotation axis coincides with the axis of the crystal ingot. The roller is then controlled to rotate to drive the crystal ingot to rotate, while also driving the base to rotate about its rotation axis. During the base's rotation, the angle detection element detects the base's rotation angle and controls the roller to stop rotating when the base's rotation angle reaches a predetermined angle. During this process, the rotation angle detection mechanism has no physical contact with the roller or the crystal ingot. Therefore, the detection accuracy of the angle detection element is not affected by the roller or the crystal ingot, resulting in high reliability. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Figure 1 FIG. 1 is a partial structural diagram of a stick gluing machine 10 provided by an embodiment of the present invention. Figure 1As shown, the stick gluing machine includes a frame 100, a roller 200 and a rotation angle detection mechanism 300. The roller 200 is rotatably arranged on the frame 100. The rotation angle detection mechanism 300 includes a mounting frame 310, a base 320 and an angle detection element 330. The mounting frame 310 is connected to the frame 100. The base 320 is rotatably arranged on the mounting frame 310, and the rotation axis of the base 320 extends along the axial direction of the roller 200. The base 320 can be at least partially located at one axial end of the roller 200, and an alignment portion 321 is further provided on the base 320. The angle detection element 330 is configured to detect the rotation angle of the base 320.

[0033] Figure 2 Schematic diagram of the application scenario of the stick gluing machine 10 is shown. Figure 2 As shown, in actual operation, the roller 200 is used to support the crystal ingot 20, and when the roller 200 rotates, it also drives the crystal ingot 20 supported thereon to rotate. The distance between the alignment portion 321 and the rotation axis of the base 320 is equivalent to the radius of the crystal ingot 20.

[0034] The stick gluing machine 10 is used to complete at least some operations in the cutting process of the crystal ingot 20. For example, the stick gluing machine 10 is used to perform crystal angle measurement on the crystal ingot 20 with the notch at the zero position, obtain the rotation angle (i.e., the preset angle) required for the crystal ingot 20 to rotate from the notch at the zero position to the notch reaching the gluing position, and control the rotation of the crystal ingot 20 until the notch of the crystal ingot 20 reaches the gluing position. The rotation angle detection mechanism 300 operates during the rotation of the crystal ingot 20.

[0035] Specifically, under the premise that the crystal ingot 20 is supported on the roller 200, the notch of the crystal ingot 20 is at the zero position, the alignment portion 321 of the base 320 is aligned with the notch of the crystal ingot 20, and the rotation axis of the base 320 coincides with the axis of the crystal ingot 20, the roller 200 is controlled to rotate to drive the crystal ingot 20 to rotate, and the base 320 is also controlled to rotate so that the alignment portion 321 of the base 320 is always aligned with the notch of the crystal ingot 20, and the rotation angle of the base 320 is detected by the angle detection element 330. When the angle detection element 330 detects that the rotation angle of the base 320 is the preset angle, the roller 200 is controlled to stop rotating.

[0036] Since the rotation angle detection mechanism 300 has no physical connection with the roller 200 and the crystal rod 20, the measurement accuracy of the angle detection element 330 is not affected by the roller 200 and the crystal rod 20, and has high reliability. It can be understood that the rotation angle of the base 320 is the same as the rotation angle of the crystal rod 20. Therefore, by detecting the rotation angle of the base 320 by the angle detection element 330 to detect the rotation angle of the crystal rod 20, the detection accuracy of the rotation angle of the crystal rod 20 can be improved, thereby reducing the deviation between the actual position of the notch of the rotated crystal rod 20 and the bonding position. In practice, the application of the utility model makes it possible to achieve a measurement accuracy of the rotation angle of the crystal rod 20 of ±0.3°.

[0037] Those skilled in the art will appreciate that the preset angle is no greater than 90°, and based on the zero position, the rotation direction of the crystal ingot 20 can be either positive or negative. In other words, based on the zero position, the rotation angle range of the crystal ingot 20 is [-90°, 90°]. Accordingly, the maximum rotation angle of the base 320 is no less than the maximum rotation angle of the crystal ingot 20. That is, based on the zero position, the rotation range of the base 320 is at least [-90°, 90°]. Of course, the rotation range of the base 320 can be even greater, for example, [-135°, 135°], [-180°, 180°], etc.

[0038] It is also understood that the number of rollers 200 can be two or more, and the two or more rollers 200 are spaced apart and arranged in parallel around a central axis. In practice, the central axis extends horizontally, and thus the rollers 200 also extend horizontally. In this way, the two or more rollers 200 can jointly support the crystal ingot 20, and the rotation of the two or more rollers 200 can drive the crystal ingot 20 to rotate. Preferably, the number of rollers 200 is an even number, and more preferably, the number of rollers 200 is two.

[0039] In an optional embodiment, the zero position is located at 12 o'clock. Those skilled in the art will appreciate that the notch may have a V-shaped cross-section, such that when the notch is at the zero position, a line connecting the tip of the V-shape and the center of the cross-section of the crystal ingot 20 extends vertically on any cross-section of the crystal ingot 20.

[0040] It can be understood that the stick gluing machine 10 includes a positioning mechanism (not shown in the figure), which is provided on the frame 100 and is used to position the crystal stick 20 carried on the roller 200 so that the notch of the crystal stick 20 is at the zero position.

[0041] Preferably, the rotation angle detection mechanism 300 has an initial state. For example, with the zero position at 12 o'clock, in this initial state, the base 320 extends vertically, and the alignment portion 321 is located above the rotation axis of the base 320. Thus, when the rotation axis of the base 320 is collinear with the axis of the crystal ingot 20 supported by the roller 200, the alignment portion 321 is aligned with the notch of the crystal ingot 20.

[0042] The roller 200 is in transmission connection with a first drive motor (not shown) and is driven to rotate by the first drive motor 200. The base 320 is in transmission connection with a second drive motor (not shown) and is driven to rotate by the second drive motor. Both the first drive motor and the second drive motor are connected to a control unit (not shown) and are controlled to operate or stop.

[0043] It can be understood that the control unit controls the operating parameters of the first drive motor and the operating parameters of the second drive motor so that when the roller 200 and the base 320 rotate, the notch of the crystal rod 20 carried on the roller 200 remains aligned with the alignment portion 321 of the base 320.

[0044] The stick gluing machine 10 may include the first driving motor and the control unit. The rotation angle detection mechanism 300 may include the second driving motor.

[0045] In an optional embodiment, the alignment portion 321 includes an integrated signal transmitter and signal receiver, the signal transmitter preferably transmits an optical signal, the signal receiver also receives an optical signal, and the signal receiver converts the optical signal into an electrical signal to determine whether the alignment portion 321 is aligned with the notch of the crystal rod 20.

[0046] Optionally, the base 320 includes an open linear scale. This open linear scale has the alignment portion 321 built into it, and its advantage lies in its high precision. When the open linear scale is used as at least a portion of the base 320, determining whether the alignment portion 321 is aligned with the notch of the crystal ingot 20 is well known to those skilled in the art and will not be elaborated upon here.

[0047] In an alternative embodiment, the base 320 is a rod-shaped structure without a grating, and the alignment portion 321 is provided on the rod-shaped structure. The alignment portion 321 is, for example, an infrared sensor with an integrated signal generator and signal receiver.

[0048] Optionally, the angle detection element 330 is an encoder. The encoder 330 can be directly or indirectly connected to the base 320. In an optional embodiment, the encoder is connected to the output shaft of the second drive motor and detects the rotation angle of the base 320 by detecting the rotation angle of the output shaft of the second drive motor.

[0049] It is understood that the stick gluing machine 10 further includes a crystal ingot measuring mechanism (not shown), which is spaced apart from the roller 200 in the axial direction of the roller 200. The end of the roller 200 away from the crystal ingot measuring mechanism is an operating end, where an operator performs predetermined operations on the crystal ingot 20, such as loading and unloading.

[0050] In some embodiments, a first positional relationship exists between the roller 200, the crystal vector measurement mechanism, and the rotation angle detection mechanism 300. Specifically, when the roller 200, the crystal vector measurement mechanism, and the base 320 are projected onto a plane parallel to the axial direction of the roller 200 and perpendicular to the base 320, the projection of the base 320 is located between the projection of the roller 200 and the projection of the crystal vector measurement mechanism. Thus, when the crystal ingot 20 rotates, the base 320 is at least partially located between the roller 200 and the crystal vector measurement mechanism.

[0051] In other embodiments, a second positional relationship exists between the roller 200, the crystal vector measurement mechanism, and the rotation angle detection mechanism 300. Specifically, when the roller 200, the crystal vector measurement mechanism, and the base 320 are projected onto a plane parallel to the axial direction of the roller 200 and perpendicular to the base 320, the projection of the base 320 is located at the end of the roller 200 that is away from the projection of the crystal vector measurement mechanism. Thus, when the crystal ingot 20 rotates, the base 320 is located at the end of the roller 200 that is away from the crystal vector measurement mechanism.

[0052] Regardless of whether the rotation angle detection mechanism 300, the crystal vector measurement mechanism, and the roller 200 are in the first positional relationship or the second positional relationship, it is preferred that the mounting frame 310 includes a movable seat 311 and a frame body 312. The movable seat 311 is movably connected to the frame 100 and can move along a preset direction, which is perpendicular to the extension direction of the roller 200. The frame body 312 is connected to the movable seat 311. The base 320 is rotatably connected to the frame body 312. By driving the frame body 312 to move along the preset direction through the movable seat 311, the relative position of the rotation angle detection mechanism 300 and the roller 200 can be changed.

[0053] As such, when the rotation angle detection mechanism 300, the crystal vector measurement mechanism, and the roller 200 are in the first positional relationship, before the crystal ingot 20 rotates, the movable seat 311 can drive the base 320 to move until the base 320 is at least partially located at one axial end of the roller 200, and the alignment portion 321 is aligned with the notch of the crystal ingot 20. Furthermore, before performing crystal vector measurement, the movable seat 311 can be moved to completely deviate from the roller 200 in a plane perpendicular to the extension direction of the roller 200, thereby preventing the rotation angle detection mechanism 300 from interfering with the crystal vector measurement.

[0054] When the rotation angle detection mechanism 300, the crystal ingot measurement mechanism, and the roller 200 are in the second positional relationship, before the crystal ingot 20 rotates, the movable seat 311 can drive the base 320 to move until the base 320 is at least partially located at one axial end of the roller 200, and the alignment portion 321 is aligned with the notch of the crystal ingot 20. Furthermore, before the operator performs the predetermined operation, the movable seat 311 is moved to completely deviate from the roller 200 in a plane perpendicular to the extension direction of the roller 200, thereby reducing the impact on the operator.

[0055] In an exemplary embodiment, the predetermined direction is a vertical direction, and when the movable seat 311 moves in a vertically upward direction, the base 320 can be at least partially located at one axial end of the roller 200, and the alignment portion 321 can be aligned with the notch on the crystal ingot 20. When the movable seat 311 moves in a vertically downward direction, the rotation angle detection mechanism 300 can be completely offset from the roller 200 in a vertical plane. In other embodiments, the predetermined direction can also be a horizontal direction.

[0056] The rotation angle detection mechanism 300 may further include a third drive motor (not shown in the figure), which is connected to the movable base 311 and is used to drive the movable base 311 to move along the preset direction.

[0057] Next, the method of using the stick glue machine 10 is described by taking the preset direction as the vertical direction, the zero position at 12 o'clock, and the rotation angle detection mechanism 300 in the initial state and completely deviated from the roller 200 in the vertical plane as an example.

[0058] The method of using the stick gluing machine 10 includes:

[0059] Step S1: The crystal ingot 20 is placed on the roller 200 , and the notch of the crystal ingot 20 is positioned at the zero position under the action of the positioning mechanism.

[0060] Step S2: Measure the crystal orientation of the crystal ingot 20 using the crystal orientation measurement mechanism.

[0061] Step S3: obtaining an angle at which the crystal ingot 20 needs to rotate when the crystal ingot 20 rotates from the current position to the notch on the notch being in the bonding position, as the preset angle.

[0062] Step S4 : Control the third driving motor to operate to drive the movable seat 311 to move vertically upward until the alignment portion 321 of the base 320 is aligned with the notch of the crystal ingot 20 .

[0063] Step S5: Control the first drive motor to operate to drive the roller 200 to rotate, thereby driving the crystal ingot 20 to rotate. Simultaneously, control the second drive motor to operate to drive the base 320 to rotate, so that the alignment portion 321 on the base 320 is always aligned with the notch of the crystal ingot 20. During the rotation of the base 320, the angle detection element 330 is used to detect the rotation angle of the base 320. When the rotation angle detected by the angle detection element 330 reaches the preset angle, the first drive motor is controlled to stop operating, and preferably, the second drive motor is also controlled to stop operating.

[0064] Wherein, the step S1, the step S2, and the step S3 can be performed with reference to the prior art.

[0065] While the present invention is disclosed above, it is not limited thereto. Persons skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims and their equivalents, the present invention is intended to encompass such modifications and variations.
