In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0030] Example 1

[0031] The following is for reference. Figures 1-7 The substrate wafer 900 visual inspection device 1000 according to an embodiment of the present invention includes a base 100, a rotating component 700, a stage 400, an adjusting component 200, a telescopic component 300, and a control component. The rotating component 700 is mounted on the base 100 and is rotatable relative to the base 100. A housing 800 is mounted on the upper part of the rotating component 700. Referring to Figure 4, three first strip-shaped holes 801 are evenly distributed circumferentially on the side wall of the housing 800. The stage 400 is mounted on the top of the housing 800. Figure 3 As shown, the upper part of the stage 400 has three radially evenly distributed strip-shaped grooves 401. Each strip-shaped groove 401 has a second strip-shaped hole 4011 at its bottom. The adjusting component 200 is placed inside the housing 800. The adjusting component 200 includes an adjusting nut 230, an adjusting screw 220, and a driving component 210. The driving component 210 is mounted on the rotating component 700. The bottom of the adjusting screw 220 is connected to the driving component 210, and the adjusting nut 230 is fitted onto the adjusting screw 220. Specifically, in this embodiment, the driving component 210 is a stepper motor. The stepper motor drives the adjusting screw 220 to rotate, thereby causing the adjusting nut 230 to move on the adjusting screw 220. The telescopic component 300 includes a tension rod 301 and a slider 302. The slider 302 is installed in the strip-shaped groove 401. A support column 500 for supporting the substrate 900 is installed on the top of the slider 302. (Refer to...) Figure 1 and Figure 5 As shown, one end of the tension rod 301 passes through the first strip hole 801 and is hinged to the side wall of the adjusting nut 230, and the other end passes through the second strip hole 4011 and is hinged to the bottom of the slider 302. The control component is connected to the drive component 210 and the power supply respectively. The control component is used to control the drive component 210 to work or stop working.

[0032] Specifically, in some embodiments, the control component of this utility model includes a controller 600 and a control panel 601. The control panel 601 includes an up button, a down button, and a stop button. (See reference...) Figure 6 As shown, the up button controls the adjusting nut 230 to rise, the down button controls the adjusting nut 230 to fall, and the stop button controls the drive component 210 to stop working. In this embodiment, the drive component 210 is a stepper motor, and the output end of the stepper motor is connected to the bottom of the adjusting screw 220. The controller 600 is electrically connected to both the stepper motor and the control panel 601. To facilitate the movement of the support column 500 to a designated position, markings indicating common substrate sheet 900 sizes such as 4-inch, 6-inch, and 8-inch can be made next to the strip groove 401. Since the tension rod 301, slider 302, and adjusting nut 230 in this embodiment are all connected by hinges, the tension rod 301 can rotate flexibly relative to the slider 302 or adjusting nut 230. Furthermore, for aesthetic purposes, the rotating component 700 in this embodiment can be a hollow structure, and the controller 600 is installed inside the rotating component 700.

[0033] For example, if an operator needs to inspect the surface defects of an 8-inch substrate 900, the support column 500 is moved to the 8-inch position. The operator presses the up button, and the controller 600 controls the stepper motor to rotate, causing the adjusting nut 230 to rise. The extension rod rises accordingly, pushing the slider 302 outwards (towards the edge of the stage 400) during the ascent. When the slider 302 reaches the 8-inch mark, the stop button is pressed, and the controller 600 stops the stepper motor. At this point, the support column 500 above the slider 302 also reaches the 8-inch mark. (Reference) Figure 1 As shown, the 8-inch substrate 900 to be inspected is then placed on the support column 500, and the operator then inspects the surface of the substrate 900. The edge of the substrate 900 can be inspected 360° by rotating the stage 400 to check for edge defects.

[0034] When inspecting the 6-inch substrate 900, press the down button. The controller 600 will control the stepper motor to rotate, causing the adjusting nut 230 to move downwards. The tension rod 301 will then move downwards, thereby moving the slider 302 inwards (towards the center of the stage 400). When the slider 302 reaches the 6-inch mark, press the stop button. The controller 600 will stop the stepper motor. At this point, the support column 500 will be at the 6-inch mark. (Refer to...) Figure 2 As shown, the 6-inch substrate 900 to be inspected is placed on the support column 500, and the operator then inspects the 6-inch substrate 900. Since the stage 400 is mounted on the rotating component 700 through the housing 800, the substrate 900 can be inspected 360° by rotating the stage 400.

[0035] refer to Figure 1 and Figure 2 As shown, in some embodiments, the rotating component 700 of this invention has a cylindrical structure, and the upper surface of the base 100 is provided with a mounting groove. The rotating component 700 is mounted in the mounting groove by bearings. In this embodiment, the rotating component 700 is mounted in the mounting groove by bearings, which reduces the friction between the rotating component 700 and the side wall of the mounting groove. This extends the service life of the rotating component 700 and makes the rotation of the rotating component 700 smoother.

[0036] In some embodiments, the support column 500 of this invention has a conical structure, which reduces the contact area with the substrate 900, thereby reducing damage to the substrate 900.

[0037] This invention can support substrates 900 of multiple sizes, enabling surface defect inspection of substrates 900 of different sizes without requiring a separate inspection stage 400 for each size of substrate 900, thus effectively saving production costs for enterprises.

[0038] Example 2

[0039] Example 2 is largely the same as Example 1, except that: (Refer to...) Figure 7 As shown, the control component in this embodiment includes an input panel 602, which is a touchscreen panel. The input panel 602 has size keys for commonly used 4-inch, 6-inch, 8-inch, and 12-inch substrates 900, as well as a reset button. The input panel 602 is electrically connected to a controller 600. The controller 600 pre-stores different sizes and their corresponding stepper motor rotation counts. The controller 600 receives the size information transmitted from the input panel 602 and controls the stepper motor to operate, causing the support column 500 to reach the corresponding size position. Specifically, when an operator needs to inspect an 8-inch substrate 900, they first press the reset button to reset the stepper motor, returning it to its initial state. (Refer to...) Figure 3 As shown, then click the 8-inch button on the input panel 602. After receiving the size information, the controller 600 controls the stepper motor to rotate. When it rotates to the number of revolutions corresponding to 8 inches, it stops rotating. At this time, the support column 500 stops at the 8-inch position. Place the 8-inch substrate 900 on the support column 500, and the staff can check the surface defects of the substrate 900.

[0040] When the staff needs to inspect the 6-inch substrate 900, the steps are the same as above. First, click the reset button on the input panel 602, and then click the 6-inch button on the input panel 602. After receiving the size information, the controller 600 controls the stepper motor to rotate. When the support column 500 reaches the 6-inch position, the controller 600 controls the stepper motor to stop working. The staff can then place the 6-inch substrate 900 on the support column 500 to inspect the surface defects of the substrate 900.

[0041] This embodiment is simpler. Each time the stage 400 is adjusted to support different substrates 900, it only needs to be reset first, and then the corresponding size is clicked on the input panel 602. Under the combined action of the stepper motor, adjusting screw 220, adjusting nut 230, tension rod 301, and slider 302, the corresponding size position can be reached. Compared with Embodiment 1, the adjustment method of this embodiment is simpler and faster, requiring no manual control and improving the accuracy of adjustment.
