Example one
Referring to fig. 1 to 4, the present embodiment provides a wafer R-axis refining apparatus 1 for refining the R-axis of a sapphire wafer 2 having an a-axis. Here, the gem wafer 2 having the axis direction a 18 means the gem wafer 2 in which the thickness direction of the gem wafer 2 is identical to the a axis direction 18 of the gem wafer 2 itself. One of the end faces of the gemstone wafer 2 along the axial direction is a bottom face, and the other end face is a top face. Optionally, the thickness of the gemstone wafer 2 is 3-7mm, for example, the thickness of the gemstone wafer 2 is 3mm, 4mm, 5mm, 6mm or 7 mm.
The wafer R-axis fine-tuning device 1 provided in this embodiment includes a light-transmitting support 15, a light source 14, an observation portion, a first polarizing plate 12, a second polarizing plate 13, a mounting body 10, and a film 16.
Hereinafter, the above-described components of the wafer R-axis fine adjustment device 1 will be specifically described.
In this embodiment, the light-transmitting support 15 is used to support the bottom surface of the gemstone wafer 2, the light source 14 is disposed at the bottom side of the light-transmitting support 15, the light source 14 can emit natural light to the light-transmitting support 15, and the light-transmitting support 15 has light-transmitting property, so that light can enter the gemstone wafer 2 through the light-transmitting support 15.
The transmission directions of the first polarizing plate 12 and the second polarizing plate 13 are parallel to each other, that is, both allow polarized light of the same vibration direction to be transmitted. The first polarizer 12 is disposed between the light transmissive support 15 and the light source 14, and the second polarizer 13 is disposed at an interval on the top side of the light transmissive support 15, such that the interval is used to accommodate the gemstone wafer 2 by having an interval between the second polarizer 13 and the light transmissive support 15. The natural light emitted from the light source 14 becomes a first polarized light beam through the filtering action of the first polarizer 12, the first polarized light beam becomes a second polarized light beam through the light-transmitting support portion 15 and the gemstone wafer 2, and the second polarized light beam becomes a third polarized light beam through the second polarizer 13.
The observation portion 19 is disposed on the top side of the second polarizer 13 to observe the light transmission of the second polarizer 13, and the light transmission observed in the observation portion 19 is the third polarized light beam, that is, the light transmission specifically refers to the brightness of the third polarized light beam. Alternatively, the observation section 19 is observed by human eyes so that the operator can move the gemstone wafer 2 while observing the brightness of the third polarized light beam.
Alternatively, the same type of polarizer is used for the first polarizer 12 and the second polarizer 13, and the transmission directions of the first polarizer 12 and the second polarizer 13 may be ensured to be parallel to each other by installing the first polarizer 12 and the second polarizer 13 in parallel to each other.
The gem wafer 2 can move on the light-transmitting support part 15, the R-axis direction 17 can also move along with the movement of the gem wafer 2, the second polarized light beam can change along with the change of the R-axis direction 17, and meanwhile, the brightness of the third polarized light beam can also change along with the change of the brightness, so that the direction characteristics of the R axis can be observed and judged through the brightness of the third polarized light beam.
The light-transmitting support 15 has a first mark portion, and the position of the first mark portion is fixed and does not change with the movement of the gemstone wafer 2. In view of this, when the brightness of the third polarized light beam is zero, the direction of the R axis is defined with reference to the first marker. That is, when the observation unit 19 observes that the light transmission of the gemstone wafer 2 is dark and opaque, the R-axis direction 17 of the gemstone wafer 2 can be determined to be a direction that is deflected by a predetermined angle 20 in the counterclockwise direction from the first marker.
Optionally, the first identification portion may be any structure capable of playing a role of identification, such as printing, protrusion, notch, and the like.
It is worth explaining that the size of the predetermined angle 20 is related to the position of the first marker and the kind of gemstone. The predetermined angle 20 will be different for the same gemstone wafer 2, with the position of the first mark being chosen differently. For the first mark portion at the same position, the predetermined angle 20 will be different if the kind of the gemstone wafer 2 is different.
In general, before the wafer R-axis measuring apparatus 1 measures the R-axis of a batch of gemstone wafers 2, the predetermined angle 20 is measured by: one gemstone wafer 2 in which the R axis has been accurately calibrated is extracted from the batch of gemstone wafers 2, the gemstone wafer 2 is used as a measurement gemstone wafer 2, the measurement gemstone wafer 2 is placed on the light-transmitting support 15, the light source 14 is turned on, the measurement gemstone wafer 2 is moved on the light-transmitting support 15, the light transmission of the measurement gemstone wafer 2 is observed through the observation unit 19 until the light transmission of the measurement gemstone wafer 2 is dark and opaque, the angle of the known R axis of the measurement gemstone wafer 2 deflected counterclockwise with respect to the first marker is measured, and the measured angle is the predetermined angle 20.
It will be understood that the cross-section defined as a section perpendicular to the axial direction is not limited to the cross-sectional shape of the gemstone 2, and may be circular, polygonal, or other regular or irregular shape.
In an alternative of the present embodiment, the adhesive film 16 includes a protective film 160 and a second identification portion provided to the protective film 160. The protective film 160 is attached to the top surface of the gemstone 2 and the second mark corresponds to the first mark, so that the top surface of the gemstone 2 can be protected by attaching the protective film 160 to the top surface of the gemstone 2 in the first aspect.
The second aspect can be on protective film 160 silk screen printing fine R axle direction 17 to avoid because silk screen printing causes stained to gem wafer 2, and then in gem wafer 2's use and installation, need not to clear up the silk screen printing vestige, be favorable to improving efficiency and the convenience that the customer used and installed gem wafer 2.
In a third aspect, the second identification portion is generally used for silk-screen logo or model information, and the second identification portion corresponds to the first identification portion, so that the directional pasting operation of the pasting film 16 can be completed quickly and accurately.
In the present embodiment, the outline of the protection film 160 is retracted by a first predetermined gap compared to the outline of the gemstone 2, so that the protection film 160 can be attached to the top surface of the gemstone 2 more smoothly. Optionally, the protection film 160 has a back adhesive so that the protection film 160 can be firmly attached to the top surface of the gemstone wafer 2.
