Description

Technical Field

[0001] This utility model relates to a visual acquisition device and a probe assembly system including the same. Background Technology

[0002] Micro-nano measurement technology is a high-tech field that has emerged in recent years. It is one of the most forward-looking and driving key areas in basic research and high-tech development, and has become a strategic high ground in international technological competition. The probes required for measurement need to be vertically fixed at the center of the suspension structure, demanding extremely high assembly precision. If the probe assembly is inaccurate, such as tilting, offsetting, or loosening, it will lead to deviations in the measurement results and reduce measurement accuracy. Traditional probe assembly methods typically rely on human visual adjustment of the relative positions of the probe and the suspension structure during the assembly process. This results in inaccurate positioning, low efficiency, and significant measurement errors, affecting production quality and efficiency. Utility Model Content

[0013] Preferably, the two opposite edge regions of the first adjusting slide plate are not covered by the second adjusting slide plate, and the number of the first adjusting slide grooves is two, with one first adjusting slide groove provided for each edge region.

[0018] In this technical solution, by setting a second recessed space, the head of the second locking bolt will not protrude to the outside, ensuring that the second locking bolt will not be disturbed by external forces after being locked, thus improving the overall safety and reliability of the device.

[0019] Preferably, there are two second adjustment grooves, which are located on both sides of the rotating support.

[0020] In this technical solution, two second adjustment grooves are provided on both sides of the rotating support, which can ensure that the second adjustment slide can slide along the extension direction of the second adjustment groove when the second adjustment slide is adjusted; and after the second locking bolt is tightened, the two sides of the second adjustment slide are balanced by force.

[0021] Preferably, the horizontal adjustment assembly includes a rotating support, the upper surface of which is recessed downward to form a rotating space, the cross-section of which is circular, and the axis of which coincides with the vertical axis of the rotating assembly; the rotating assembly includes a rotating base column and an upper support member, the outer peripheral surface of which mates with the inner peripheral surface of the rotating space, the upper support member being fixed to the upper end surface of the rotating base column, and the upper support member cooperating with the lifting assembly.

After rotating into position, the rotating base column and the rotating support are relatively fixed, thus fixing the rotating component and the horizontal adjustment component relatively.

[0023] Preferably, the rotating assembly further includes a rotating rod fixed to the outer peripheral surface of the upper support member, the rotating rod extending outward in a direction perpendicular to the vertical axis.

[0024] In this technical solution, when it is necessary to rotate the rotating base column, the operator can grasp the rotating rod to drive the upper support and the rotating base column to rotate together, thereby realizing the angle adjustment of the rotating component, which makes it convenient for the operator to control the rotation of the upper support and the rotating base column.

[0025] Preferably, the rotating support is provided with a locking hole that extends radially through it; the rotating assembly also includes a fixing bolt, the thread of which is inserted into the locking hole, the thread of which is threadedly connected to the locking hole, and the head of the thread of which can abut against the outer circumferential surface of the rotating base column.

[0026] In this technical solution, after the rotating component is rotated to the position, the fixing bolt is tightened inward, so that the head of the fixing bolt can abut against the outer circumferential surface of the rotating base column, thereby fixing the rotating base column and the rotating support relative to each other, and thus fixing the rotating component and the horizontal adjustment component relative to each other.

[0027] Preferably, the upper support member includes a support base and a vertical support block, the support base being fixed to the upper end face of the rotating base column; the vertical support block being fixed to the upper surface of the support base, and the vertical support block cooperating with the lifting assembly.

[0028] In this technical solution, a vertical support block is used to install a lifting component. The lifting component can move vertically on the vertical support block, thereby adjusting the vertical height of the camera.

[0030] In this technical solution, when the adjustment handwheel is manually turned, the driving force is transmitted to the adjustment gear. The rotating adjustment gear meshes with the adjustment rack, converting the rotational motion of the adjustment gear into the linear motion of the adjustment rack, thereby driving the vertical moving block connected to the adjustment rack to move vertically. When the adjustment handwheel is released, the weight of the load will keep the adjustment gear and the adjustment rack tightly meshed, thereby preventing the vertical moving block from moving accidentally in the vertical direction and keeping the position of the camera stable.

[0031] Preferably, the lifting assembly includes a vertical moving block, and the side of the vertical moving block is provided with a horizontally arranged third mounting hole; the tilting assembly includes a horizontal fixing plate, a vertical connecting plate and a third locking bolt, the horizontal fixing plate fixing the camera; the vertical connecting plate is fixed to the horizontal fixing plate, the vertical connecting plate is in contact with the surface of the vertical moving block where the third mounting hole is provided, an arc-shaped groove is formed on the vertical connecting plate, the central axis of the arc-shaped groove is a horizontal axis; the third mounting hole is located in the arc-shaped groove; the screw of the third locking bolt passes laterally through the arc-shaped groove and is threadedly connected to the third mounting hole, and the head of the third locking bolt presses against the surface of the vertical connecting plate.

[0032] In this technical solution, by changing the locking position of the third locking bolt in the arc-shaped groove, the angle of the horizontal fixing plate around the horizontal axis can be changed, thereby adjusting the angle of the camera around the horizontal axis.

[0033] This utility model also provides a probe assembly system, including an installation platform, a probe assembly suspension clamp, a three-axis displacement stage, and a vision acquisition device. The probe assembly suspension clamp is fixed on the installation platform and is used to suspend the probe and control the probe to be pressed down and adhered to the suspension structure. The three-axis displacement stage is located below the probe assembly suspension clamp, and the side of the three-axis displacement stage facing the probe assembly suspension clamp is used to fix the suspension structure. The three-axis displacement stage can move horizontally or vertically. The vision acquisition device is fixed on the installation platform and, as described in the above technical solution, is signal-connected to the three-axis displacement stage.

[0034] In this technical solution, the relative position between the central circular surface of the suspension structure and the bottom surface of the probe is monitored in real time by a vision acquisition device. The relative distance between the central circular surface of the suspension structure and the bottom surface of the probe is calculated, and the three-axis displacement stage moves according to the calculated relative distance. This allows the alignment of the central circular surface of the suspension structure and the bottom surface of the probe to be achieved automatically, improving the alignment accuracy and speed.

[0035] Preferably, there are two visual acquisition devices, namely an X-axis visual acquisition device and a Y-axis visual acquisition device. The lens shooting directions of the X-axis visual acquisition device and the Y-axis visual acquisition device are both set horizontally, and the lens shooting directions of the X-axis visual acquisition device and the Y-axis visual acquisition device are perpendicular to each other.

[0036] In this technical solution, two mutually perpendicular X-axis visual acquisition devices and Y-axis visual acquisition devices can capture images of the relative positions of the central circular surface of the suspension structure and the bottom surface of the probe from two perpendicular angles. When calculating the relative distance, there are two relative position images in different directions for reference, which ensures the reliability of subsequent data calculation.

[0037] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0038] The positive and progressive effects of this utility model are as follows:

[0039] The aforementioned visual acquisition device and the probe assembly system including it allow the visual acquisition device to flexibly adjust the position of the camera in four dimensions: horizontal, vertical, vertical rotation, and horizontal rotation. This ensures optimal image acquisition of the relative position of the central circular surface of the suspension structure and the bottom surface of the probe. By monitoring the relative position between the central circular surface of the suspension structure and the bottom surface of the probe in real time, the visual acquisition device calculates the relative distance between them and moves the three-axis displacement stage according to the calculated relative distance. This enables fully automatic alignment between the central circular surface of the suspension structure and the bottom surface of the probe, improving alignment accuracy and speed.

[0092] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0093] Figure 1 and Figure 2 The diagram shows the structure of the probe assembly system of this utility model. The probe assembly system includes an installation platform 100, a probe assembly suspension clamp 200, and a three-axis displacement stage 300. The probe assembly suspension clamp 200 is fixed on the installation platform 100 and is used to suspend the probe 500 and control the downward pressure of the probe 500. The three-axis displacement stage 300 is located below the probe assembly suspension clamp 200. The side of the three-axis displacement stage 300 facing the probe assembly suspension clamp 200 is used to fix the suspension structure 600. The three-axis displacement stage 300 can move horizontally or vertically.

[0094] The assembled probe 500 needs to be vertically fixed to the center of the suspension structure 600. When the probe 500 is suspended above the suspension structure 600, the probe assembly and holding fixture 200 keeps the probe 500 vertical, while the three-axis displacement stage 300 can move horizontally or vertically, so that the center point of the central circular surface 601 of the suspension structure 600 and the center point of the bottom end surface 501 of the probe 500 are vertically aligned and maintained at a preset distance. Finally, the probe assembly and holding fixture 200 presses the probe 500 vertically downward, so that the bottom end surface 501 of the probe 500 contacts and adheres to the central circular surface 601 of the suspension structure 600, thus fixing the probe 500 and the suspension structure 600.

[0095] To ensure that the relative positions of the probe 500 and the suspension structure 600 are aligned vertically, the probe assembly system also includes a vision acquisition device 400, which is fixed on the mounting platform 100. The vision acquisition device 400 is used to acquire images of the relative positions of the central circular surface 601 of the suspension structure 600 and the bottom end surface 501 of the probe 500. The three-axis displacement stage 300 is used to move horizontally with reference to the relative position images until the center point of the central circular surface 601 of the suspension structure 600 and the center point of the bottom end surface 501 of the probe 500 coincide in the vertical direction and maintain a preset distance.

[0096] The visual acquisition device 400 monitors the relative position of the center circular surface 601 of the suspension structure 600 and the bottom end surface 501 of the probe 500 in real time, calculates the relative distance, and moves the three-axis displacement stage 300 according to the calculated relative distance. This allows the alignment of the center circular surface 601 of the suspension structure 600 and the bottom end surface 501 of the probe 500 to be achieved automatically, improving the alignment accuracy and speed.

[0097] Figures 3 to 7 The diagram illustrates an embodiment of a visual acquisition device 400. This device includes a horizontal adjustment assembly 1, a rotation assembly 2, a lifting assembly 3, a tilting assembly 4, and a camera 5. The horizontal adjustment assembly 1 is fixed to the mounting platform 100, and its relative position to the platform 100 can be adjusted horizontally. The rotation assembly 2 is fixed to the horizontal adjustment assembly 1 and can rotate around the vertical axis of the horizontal adjustment assembly 1 to adjust its relative position. The lifting assembly 3 is fixed to the rotation assembly 2 and can adjust its relative position to the rotation assembly 2 vertically. The tilting assembly 4 is fixed to the lifting assembly 3 and can rotate along the horizontal axis to adjust its relative position to the lifting assembly 3. The vertical axis is perpendicular to the horizontal axis. The camera 5 is fixed to the tilting assembly 4.

[0098] The horizontal adjustment component 1 can adjust the position of the camera 5 horizontally; the rotation component 2 can rotate the camera 5 around the vertical axis; the lifting component 3 can adjust the position of the camera 5 vertically; and the tilting component 4 can rotate the camera 5 around the horizontal axis. Through the structural design of the above-mentioned visual acquisition device 400, the position of the camera 5 can be adjusted in various directions, thereby ensuring that the camera 5 can be aligned with the central circular surface 601 of the suspension structure 600 and the bottom end surface 501 of the probe 500 for image capture.

[0099] like Figures 3 to 5As shown, the horizontal adjustment assembly 1 includes a first adjustment slide plate 11, a second adjustment slide plate 12, and a rotating support 13. The first adjustment slide plate 11 is fixed on the mounting platform 100, and the relative position of the first adjustment slide plate 11 and the mounting platform 100 can be adjusted in the horizontal direction. The second adjustment slide plate 12 is fixed on the first adjustment slide plate 11, and the relative position of the second adjustment slide plate 12 and the first adjustment slide plate 11 can be adjusted in the horizontal direction. The adjustment direction of the second adjustment slide plate 12 is perpendicular to the adjustment direction of the first adjustment slide plate 11. The rotating support 13 is fixed on the second adjustment slide plate 12, and the rotating assembly 2 is fixed on the rotating support 13. The rotating assembly 2 can rotate relative to the rotating support 13 about a vertical axis.

[0100] The first adjustment slide plate 11 and the second adjustment slide plate 12 are adjusted in two mutually perpendicular adjustment directions to adapt to the adjustment needs of multiple positions of the camera 5 in the horizontal direction; the rotating support 13 is used as a rotation support for the rotating component 2, so that the rotating component 2 can rotate relative to the rotating support 13 around the vertical axis.

[0101] like Figure 5 As shown, the first adjusting slide plate 11 is provided with a first adjusting groove 111, which extends from the upper surface to the lower surface of the first adjusting slide plate 11. The extending direction of the first adjusting groove 111 is consistent with the adjustment direction of the first adjusting slide plate 11. The mounting platform 100 is provided with a vertically arranged first mounting hole corresponding to the position of the first adjusting groove 111. The horizontal adjustment assembly 1 also includes a first locking bolt (not shown in the figure). The screw of the first locking bolt passes vertically through the first adjusting groove 111 and is threadedly connected to the first mounting hole. The head of the first locking bolt presses against the upper surface of the first adjusting slide plate 11. When the first adjusting slide plate 11 is adjusted to the correct position, the head of the first locking bolt presses against the upper surface of the first adjusting slide plate 11, thereby fixing the position of the first adjusting slide plate 11 relative to the mounting platform 100.

[0102] In this design, the upper surface of the first adjusting slide plate 11 surrounds the area of ​​the first adjusting slide groove 111 to form a first recessed space 112. The head of the first locking bolt is located within the first recessed space 112, and the head of the first locking bolt presses against the bottom surface of the first recessed space 112. By setting the first recessed space 112, the head of the first locking bolt will not protrude to the outside, ensuring that the first locking bolt will not be disturbed by external forces after being locked, thus improving the overall safety and reliability of the device.

[0103] In this design, the two opposite edge regions 113 of the first adjusting slide plate 11 are not covered by the second adjusting slide plate 12. There are two first adjusting grooves 111, one for each edge region 113. Correspondingly, there are also two first locking bolts. This ensures that when the first adjusting slide plate 11 is in the adjusted position, it can slide along the extension direction of the first adjusting groove 111; and after the first locking bolts are tightened, the forces on both sides of the first adjusting slide plate 11 are balanced.

[0104] like Figure 5 As shown, the second adjusting slide plate 12 is provided with a second adjusting groove 121, which extends from the upper surface to the lower surface of the second adjusting slide plate 12. The extension direction of the second adjusting groove 121 is consistent with the adjustment direction of the second adjusting slide plate 12. The first adjusting slide plate 11 is provided with a vertically arranged second mounting hole 114 corresponding to the position of the second adjusting groove 121. The horizontal adjustment assembly 1 also includes a second locking bolt (not shown in the figure). The screw of the second locking bolt passes vertically through the second adjusting groove 121 and is threadedly connected to the second mounting hole 114. The head of the second locking bolt presses against the upper surface of the second adjusting slide plate 12. When the second adjusting slide plate 12 is adjusted to the correct position, the head of the second locking bolt presses against the upper surface of the second adjusting slide plate 12, thereby fixing the relative positions of the second adjusting slide plate 12 and the first adjusting slide plate 11.

[0105] The upper surface of the second adjusting slide plate 12 surrounds the area of ​​the second adjusting slide groove 121 to form a second recessed space 122. The head of the second locking bolt is located within the second recessed space 122, and the head of the second locking bolt presses against the bottom surface of the second recessed space 122. By setting the second recessed space 122, the head of the second locking bolt will not protrude to the outside, ensuring that the second locking bolt will not be disturbed by external forces after being locked, thus improving the overall safety and reliability of the device.

[0106] There are two second adjusting slide grooves 121, located on opposite sides of the rotating support 13. Correspondingly, there are also two second locking bolts on each side of the rotating support 13. This ensures that the second adjusting slide plate 12 can slide along the extension direction of the second adjusting slide groove 121 when adjusting its position; and that the forces on both sides of the second adjusting slide plate 12 are balanced after the second locking bolts are tightened.

[0107] like Figures 5 to 6As shown, the rotating component 2 is mounted on the rotating support 13 of the horizontal adjustment component 1. The upper surface of the rotating support 13 is recessed downward to form a rotating space 131. The cross-section of the rotating space 131 is circular, and the axis of the rotating space 131 coincides with the vertical axis of the rotating component 2. The rotating component 2 includes a rotating base column 21 and an upper support member 22. The outer peripheral surface of the rotating base column 21 is matched with the inner peripheral surface of the rotating space 131. The upper support member 22 is fixed to the upper end surface of the rotating base column 21 and is matched with the lifting component 3.

[0108] During installation, the rotating base column 21 is installed within the rotation space 131 of the rotating support 13, and the rotating base column 21 can rotate around the vertical axis within the rotation space 131. After rotating into position, the rotating base column 21 and the rotating support 13 are relatively fixed, so that the rotating assembly 2 and the horizontal adjustment assembly 1 are relatively fixed.

[0109] like Figure 6 As shown, the rotating assembly 2 also includes a rotating rod 23, which is fixed to the outer circumferential surface of the upper support member 22 and extends outward in a direction perpendicular to the vertical axis. When it is necessary to rotate the rotating base column 21, grasping the rotating rod 23 will cause the upper support member 22 and the rotating base column 21 to rotate together, thereby achieving angle adjustment of the rotating assembly 2. The rotating rod 23 facilitates the operator's control of the rotation of the upper support member 22 and the rotating base column 21.

[0110] like Figures 5 to 6 As shown, the rotating support 13 has a radially penetrating locking hole 132; the rotating assembly 2 also includes a fixing bolt 24, the screw of which is inserted into the locking hole 132, and the screw of the fixing bolt 24 is threadedly connected to the locking hole 132. The head of the screw of the fixing bolt 24 can abut against the outer circumferential surface of the rotating base column 21. When the rotating assembly 2 is rotated into position, the fixing bolt 24 is tightened inward, so that the head of the screw of the fixing bolt 24 can abut against the outer circumferential surface of the rotating base column 21, thereby fixing the rotating base column 21 and the rotating support 13 relative to each other, thus fixing the rotating assembly 2 and the horizontal adjustment assembly 1 relative to each other.

[0111] like Figures 6 to 8 As shown, the upper support member 22 includes a support base 221 and a vertical support block 222. The support base 221 is fixed to the upper end face of the rotating base column 21. The vertical support block 222 is fixed to the upper surface of the support base 221 and cooperates with the lifting assembly 3. The vertical support block 222 is used to install the lifting assembly 3, which can move vertically on the vertical support block 222 to adjust the vertical height of the camera 5.

[0112] Specifically, the vertical support block 222 has a vertical guide rail 223 on its surface facing the lifting assembly 3; the lifting assembly 3 includes a vertical moving block 31, an adjusting gear 32, and an adjusting handwheel 33. The vertical moving block 31 has a guide groove 311 on its side facing the vertical support block 222, and the guide groove 311 is mounted on the vertical guide rail 223; the vertical guide rail 223 has a vertically extending adjusting rack 224 on its side facing the guide groove 311; the adjusting gear 32 is mounted in the guide groove 311, and the adjusting gear 32 meshes with the adjusting rack 224; the rotating shaft of the adjusting handwheel 33 passes through the vertical moving block 31 and is inserted into the guide groove 311, and the adjusting gear 32 and the rotating shaft of the adjusting handwheel 33 are coaxially fixed; when the adjusting handwheel 33 rotates, it drives the adjusting gear 32 to move on the adjusting rack 224.

[0113] Among them, the vertical guide rail 223 is a dovetail groove guide rail. The dovetail groove guide rail has high rigidity and stability, can effectively withstand lateral forces, and ensure the smoothness and accuracy of the vertical moving block 31 when it moves vertically.

[0114] When the adjustment handwheel 33 is manually turned, the driving force is transmitted to the adjustment gear 32. The rotating adjustment gear 32 meshes with the adjustment rack 224, converting the rotational motion of the adjustment gear 32 into the linear motion of the adjustment rack 224, thereby driving the vertical moving block 31 connected to the adjustment rack 224 to move vertically. When the adjustment handwheel 33 is released, the weight of the load will keep the adjustment gear 32 and the adjustment rack 224 tightly meshed, thereby preventing the vertical moving block 31 from moving accidentally in the vertical direction and keeping the position of the camera 5 stable.

[0115] like Figures 8 to 9 As shown, the lifting assembly 3 is also fixed to the tilting assembly 4, which allows the angle of the camera 5 around the horizontal axis to be adjusted. Specifically, the vertical moving block 31 is provided with a horizontally positioned third mounting hole. The tilting assembly 4 includes a horizontal fixing plate 41, a vertical connecting plate 42, and a third locking bolt. The horizontal fixing plate 41 fixes the camera; the vertical connecting plate 42 is fixed to the horizontal fixing plate 41, and the vertical connecting plate 42 is in contact with the surface of the vertical moving block 31 where the third mounting hole is located. An arc-shaped groove 421 is formed on the vertical connecting plate 42, and the central axis of the arc-shaped groove 421 is the horizontal axis; the third mounting hole is located in the arc-shaped groove 421; the screw of the third locking bolt passes laterally through the arc-shaped groove 421 and is threadedly connected to the third mounting hole, and the head of the third locking bolt presses against the surface of the vertical connecting plate 42.

[0116] By changing the locking position of the third locking bolt in the arc-shaped groove 421, the angle of the horizontal fixing plate 41 around the horizontal axis can be changed, thereby adjusting the angle of the camera 5 around the horizontal axis.

[0117] The vertical connecting plate 42 and the horizontal fixing plate 41 are perpendicular to each other and form an L-shape. The camera 5 is fixed on the horizontal fixing plate 41. The shapes of the vertical connecting plate 42 and the horizontal fixing plate 41 are adapted to the shape of the camera 5's chassis. The vertical connecting plate 42 is used to fix the vertical moving block 31, and the horizontal fixing plate 41 is used to fix the camera 5's chassis. This facilitates the installation of the camera 5 while also ensuring the structural compactness of the tilting component 4 and the lifting component 3 assembly.

[0118] The vertical connecting plate 42 surrounds the arc-shaped groove 421 to form an arc-shaped recessed space 422. The head of the third locking bolt is located within the arc-shaped recessed space 422, and the head of the third locking bolt presses against the bottom surface of the arc-shaped recessed space 422. By setting the arc-shaped recessed space 422, the head of the third locking bolt will not protrude to the outside, ensuring that the third locking bolt will not be disturbed by external forces after being locked, thus improving the overall safety and reliability of the device.

[0119] Using the aforementioned visual acquisition device 400 in the probe assembly system allows for flexible adjustment of the camera 5's position along four dimensions: horizontal, vertical, vertical rotation, and horizontal rotation. This ensures optimal performance when the camera 5 acquires images of the relative positions of the central circular surface 601 of the suspension structure 600 and the bottom surface 501 of the probe 500.

[0120] The mounting platform 100 has several mounting positions, all of which can be installed and fixed to the first adjustment slide plate 11 of the visual acquisition device 400, and the visual acquisition device 400 can be installed according to different image acquisition needs.

[0121] In this embodiment, there are two visual acquisition devices 400, namely an X-direction visual acquisition device 401 and a Y-direction visual acquisition device 402. The lens shooting directions of the X-direction visual acquisition device 401 and the Y-direction visual acquisition device 402 are both set horizontally, and the lens shooting directions of the X-direction visual acquisition device 401 and the Y-direction visual acquisition device 402 are perpendicular to each other.

[0122] Using two mutually perpendicular X-axis visual acquisition devices 401 and Y-axis visual acquisition devices 402, images of the relative positions of the central circular surface 601 of the suspension structure 600 and the bottom surface 501 of the probe 500 can be captured from two perpendicular angles. When calculating the relative distance, having two relative position images in different directions provides a reference, ensuring the reliability of subsequent data calculations.

[0123] The probe assembly system also includes a control module, which is signal-connected to the three-axis displacement stage 300 and the vision acquisition device 400. The vision acquisition device 400 transmits relative position images to the control module, which calculates the relative distance between the central circular surface 601 of the suspension structure 600 and the bottom end surface 501 of the probe 500 based on the relative position images. The control module also controls the movement of the three-axis displacement stage 300 based on the relative distance until the center point of the central circular surface 601 of the suspension structure 600 and the center point of the bottom end surface 501 of the probe 500 coincide in the vertical direction and maintain a preset distance. Controlling the movement of the three-axis displacement stage 300 through the control module is more precise and faster than manual adjustment.

[0124] The visual acquisition device 400 monitors in real time the relative position between the central circular surface 601 of the suspension structure 600 and the bottom end surface 501 of the probe 500, calculates the relative distance between the central circular surface 601 of the suspension structure 600 and the bottom end surface 501 of the probe 500, and moves the three-axis displacement stage 300 according to the calculated relative distance, so that the alignment of the central circular surface 601 of the suspension structure 600 and the bottom end surface 501 of the probe 500 can be achieved automatically, improving the alignment accuracy and alignment speed.
