Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a clamping device. Background Technology

[0002] Scanning Capacitance Microscope (SCM) can be used to detect the morphology, size, and characteristics of ion implantation distribution areas, and can form planar differential capacitance images of the ion implantation area.

[0003] The cross-section of the SCM sample determines the quality of SCM testing. During analysis and testing, the surface of the SCM sample needs to be kept horizontal to ensure the accuracy and reliability of the measurement.

[0004] In traditional techniques, SCM samples are fixed to the holder by screw compression. However, the screw fixing method results in a small contact area with the sample, making it easy to crush the sample. Utility Model Content

[0005] Therefore, it is necessary to provide a clamping device to address the problem of SCM being difficult to clamp.

[0006] A clamping device, the clamping device comprising:

[0007] Base;

[0008] A clamping mechanism, disposed on the base, is used to clamp a target sample. The clamping mechanism includes a first rotating member and a second rotating member disposed opposite to each other, and the distance between the first rotating member and the second rotating member is configured to be adjustable.

[0009] The pressure-applying mechanism includes a first support member and a pressing assembly. The first support member is located on the base, and the pressing assembly is at least partially located above the clamping mechanism. The pressing assembly is slidably connected to the first support member and is movable along the extension direction of the first support member.

[0010] In one embodiment, the clamping mechanism further includes a second support member and a third support member disposed on the base and arranged opposite to each other, a first shaft inserted into the second support member, a second shaft inserted into the second support member, the first rotating member being rotatably connected to the second support member through the first shaft, and the second rotating member being rotatably connected to the third support member through the second shaft.

[0011] In one embodiment, an elastic element is provided between the first rotating member and the second supporting member; and / or,

[0012] An elastic element is provided between the second rotating member and the third supporting member.

[0013] In one embodiment, the pressure-applying mechanism includes a sliding seat with a through hole, the sliding seat being sleeved on the first support member through the through hole, and the pressing assembly being disposed on the sliding seat.

[0014] In one embodiment, the pressure-applying mechanism further includes a locking member disposed on the first support member for limiting the displacement of the sliding seat.

[0015] In one embodiment, the weight of the sliding seat is greater than the mass of the crimping assembly.

[0016] In one embodiment, the crimping assembly includes a first crimping member and a second crimping member, the first crimping member and the second crimping member being spaced apart and located on opposite sides of the axis of the first rotating member.

[0017] In one embodiment, the interval is smaller than the width of the target sample.

[0018] In one embodiment, the first pressing member and the second pressing member are disc-shaped structures, with the disc surfaces of the first pressing member and the second pressing member facing each other.

[0019] In one embodiment, the plane at the bottom of the crimping assembly is parallel to the surface of the base.

[0020] The aforementioned clamping device includes a base, a clamping mechanism, and a pressure-applying mechanism. The base supports the clamping and pressure-applying mechanisms. The clamping mechanism clamps the target sample, and the pressure-applying mechanism applies pressure to the target sample, adjusting its angle to meet requirements. Specifically, the clamping mechanism includes a first rotating member and a second rotating member. When the target sample is positioned between the first and second rotating members, the target sample, the first rotating member, and the second rotating member can rotate simultaneously. Thus, when the pressure-applying mechanism applies pressure to the target sample, it causes the target sample to rotate, thereby adjusting the rotation angle of the target sample's upper surface to meet usage requirements. Compared to traditional methods that use screws for fixing, the clamping device provided in this application avoids crushing the target sample during fixing and can replace human judgment of the sample surface angle, automatically adjusting the placement angle of the target sample, significantly saving time spent on repeated testing due to uneven placement.

[0027] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0028] See Figure 1 , Figure 1 A schematic diagram of the clamping device according to an embodiment of the present invention is shown. The clamping device provided in this embodiment includes a base 10, a clamping mechanism 20, and a pressure applying mechanism 30. The base 10 supports the clamping mechanism 20 and the pressure applying mechanism 30. The clamping mechanism 20 clamps a target sample 40; exemplarily, the target sample 40 may be an SCM sample. The pressure applying mechanism applies pressure to the target sample 40 when it is clamped by the clamping mechanism 20, ensuring that its upper surface meets the required angle.

[0029] Specifically, the clamping mechanism 20 is disposed on the base 10 for clamping the target sample 40. The clamping mechanism 20 includes a first rotating member 21 and a second rotating member 22 disposed opposite to each other, and the distance between the first rotating member 21 and the second rotating member 22 is configured to be adjustable.

[0030] The clamping mechanism 20 includes a first rotating member 21 and a second rotating member 22 arranged opposite to each other. In use, the target sample 40 is placed between the first rotating member 21 and the second rotating member 22, and the first rotating member 21 and the second rotating member 22 work together to achieve the clamping function. Both the first rotating member 21 and the second rotating member 22 can rotate. When the target sample 40 is placed between the first rotating member 21 and the second rotating member 22, the target sample 40, the first rotating member 21 and the second rotating member 22 can rotate along with it when a force is applied to the target sample 40.

[0031] The distance between the first rotating member 21 and the second rotating member 22 is configured to be adjustable, thereby enabling the clamping of target samples 40 of different sizes, such as SCM samples of different widths. Furthermore, the first rotating member 21 and the second rotating member 22 are subjected to elastic force, and when the target sample 40 is located between the first rotating member 21 and the second rotating member 22, pressure can be applied to the target sample 40 to fix it in place.

[0032] The pressure applying mechanism 30 includes a first support member 31 and a crimping assembly 32. The first support member 31 is located on the base 10 and serves a supporting function. The crimping assembly 32 is at least partially located above the clamping mechanism 20 and is supported by the first support member 31. The crimping assembly 32 is slidably connected to the first support member 31 and can move along the extending direction of the first support member 31. Exemplarily, the extending direction of the first support member 31 is perpendicular to the base 10.

[0033] Understandably, the crimping assembly 32 is vertically higher than the clamping mechanism 20, thus providing sufficient room for movement. It can translate along the extension direction of the first support member 31, moving towards or away from the clamping mechanism 20. This provides the crimping assembly 32 with a flexible operating range, adapting to different working requirements. In actual operation, when the target sample 40 is already clamped on the clamping mechanism 20, the crimping assembly 32 can gradually move downwards from above the clamping mechanism 20, approaching it until it contacts the target sample 40. At this point, the crimping assembly 32 applies a certain pressure to the target sample 40.

[0034] Since the first rotating member 21 and the second rotating member 22 on the clamping mechanism 20 can rotate independently, when the top plane of the target sample 40 has an inclined angle, presenting a situation where one side is higher than the other, the pressing assembly 32 will first contact the higher side when it moves down. Under the pressure of the pressing assembly 32, the higher side of the target sample 40 is subjected to a downward force, which drives the first rotating member 21 and the second rotating member 22 to rotate, causing the height of the higher side of the target sample 40 to decrease and the height of the lower side to increase. This process continues until the top plane of the target sample 40 is completely flush with the bottom plane of the pressing assembly 32, at which point the first rotating member 21 and the second rotating member 22 stop rotating.

[0035] The crimping assembly 32 and the clamping mechanism 20 can achieve precise cooperation and coordinated movement, which not only improves the efficiency of operation, but also enhances the stability and accuracy of the clamping process. As the target sample 40 rotates under the pressure of the crimping assembly 32, the rotating parts of the clamping mechanism 20 adjust synchronously, so that the rotation angle of the target sample 40 can be adjusted while clamping the target sample 40.

[0036] The aforementioned clamping device includes a base 10, a clamping mechanism 20, and a pressure applying mechanism 30. The base 10 supports the clamping mechanism 20 and the pressure applying mechanism 30. The clamping mechanism 20 clamps the target sample 40, and the pressure applying mechanism 30 applies pressure to the target sample 40, adjusting its angle to meet requirements. Specifically, the clamping mechanism 20 includes a first rotating member 21 and a second rotating member 22. When the target sample 40 is located between the first rotating member 21 and the second rotating member 22, the target sample 40, the first rotating member 21, and the second rotating member 22 can rotate simultaneously. Thus, when the pressure applying mechanism 30 applies pressure to the target sample 40, it causes the target sample 40 to rotate, thereby adjusting the rotation angle of the upper surface of the target sample 40 to meet usage requirements. Compared to the traditional method of fixing with screws, the clamping device provided in this application can avoid crushing the target sample 40 during fixing, and can replace the human eye to judge the angle of the sample surface, realize automatic adjustment of the placement angle of the target sample 40, and greatly save the time of repeated testing due to uneven placement.

[0037] Optionally, the surfaces of the first rotating member 21 and the second rotating member 22 may be configured with special clamping materials or clamping structures such as rubber pads to enhance their friction and clamping force. The rubber pads can also cushion the target sample 40 to ensure that the target sample 40 is not damaged during the clamping process.

[0038] See also Figures 2-4 , Figure 2 A front view schematic diagram of the clamping device in one embodiment is shown. Figure 3A side view of the clamping device in one embodiment is shown. Figure 4 A top view of the clamping device in one embodiment is shown. In some embodiments, the clamping mechanism 20 further includes a second support member 23 and a third support member 24 disposed on the base 10 and disposed opposite to each other, a first shaft inserted into the second support member 23, a second shaft inserted into the second support member 23, a first rotating member 21 rotatably connected to the second support member 23 via the first shaft, and a second rotating member 22 rotatably connected to the third support member 24 via the second shaft.

[0039] The second support member 23 and the third support member 24 are disposed on the base 10 and are used to provide support. The second support member 23 is used to support the first rotating member 21, and the third support member 24 is used to support the second rotating member 22.

[0040] In order to enable the first rotating member 21 to rotate, a through hole is provided on the second support member 23. The first shaft is inserted into the second support member 23 through the through hole. The first rotating member 21 is connected to the first shaft. If the axis of the first rotating member 21 can coincide with the axis of the first shaft, the first rotating member 21 can rotate around the first shaft as the rotation center.

[0041] In order to enable the second rotating member 22 to rotate, a through hole is provided on the third support member 24. The second shaft is inserted into the third support member 24 through the through hole. The second rotating member 22 is connected to the second shaft. If the axis of the second rotating member 22 can coincide with the axis of the second shaft, the second rotating member 22 can rotate around the second shaft as the rotation center.

[0042] In some embodiments, an elastic element 25 is provided between the first rotating member 21 and the second support member 23. In other embodiments, an elastic element 25 is provided between the second rotating member 22 and the third support member 24. This allows the first rotating member 21 and the second rotating member 22 to have restoring force under the action of the elastic element 25. When subjected to external compressive force, the elastic element 25 generates a counterforce, restoring the first rotating member 21 and the second rotating member 22 to their original state. In this way, the elastic element 25 plays a role in buffering and adjustment.

[0043] For example, when the target sample 40 is clamped between the first rotating member 21 and the second rotating member 22, the presence of the elastic member 25 allows the two rotating members to properly clamp the target sample 40 under pressure. During the clamping process of the target sample 40, the restoring force provided by the elastic member 25 ensures that the rotating members can apply a uniform clamping force to the target sample 40. The design of the elastic member 25 not only improves the stability of the clamping process, but also ensures that the target sample 40 can be firmly fixed during the clamping process, avoiding loosening or slippage.

[0044] Furthermore, depending on the specific characteristics of the target sample 40, the elastic force of the elastic element 25 can be adjusted to regulate the clamping force, thereby achieving precise fixation of the target sample 40. For example, the elastic element 25 can be a spring.

[0045] In some embodiments, the pressing mechanism 30 includes a sliding seat 33 with a through hole. The sliding seat 33 is sleeved on the first support member 31 through the through hole, and the pressing assembly 32 is disposed on the sliding seat 33. The sliding seat 33 serves as a support for the pressing assembly 32 and can provide support force to the pressing assembly 32. Thus, when the sliding seat 33 slides along the first support member 31, it can drive the pressing assembly 32 to move, causing the pressing assembly 32 to move up and down, realizing movement away from or towards the clamping mechanism 20.

[0046] The sliding seat 33 ensures that the position of the crimping assembly 32 can be precisely adjusted according to actual needs. Especially when clamping or crimping the target sample 40, the sliding of the sliding seat 33 and the coordinated movement of the crimping assembly 32 ensure a uniform distribution of the crimping force of the crimping assembly 32 on the target sample 40 and high operational efficiency.

[0047] For example, the weight of the sliding seat 33 is greater than the mass of the pressing assembly 32, which can effectively enhance the stability required by the pressing mechanism 30 during operation. Specifically, the larger mass of the sliding seat 33 enables it to resist interference from external unstable factors when sliding along the first support member 31, thereby reducing vibration or shaking that may occur during sliding.

[0048] Furthermore, the weight of the sliding seat 33 is significantly greater than the mass of the crimping assembly 32, enabling it to provide stronger support and greater stability during the application of pressure. This design uses the sliding seat 33 as a counterweight slider, fully utilizing its larger mass to improve the balance and stability of the sliding seat 33 as it moves along the first support member 31. The larger mass helps maintain a smoother movement trajectory for the crimping assembly 32, thereby improving the operational accuracy of the crimping assembly 32.

[0049] In some embodiments, the pressure applying mechanism 30 further includes a locking element disposed on the first support member 31 for limiting the displacement of the sliding seat 33. The main function of the locking element is to ensure that the sliding seat 33 does not move unnecessarily under certain operating conditions, thereby providing additional safety and accuracy.

[0050] During implementation, the locking component can cooperate with the first support component 31 in different ways, such as through mechanical snap-fit, bolt connection, or spring-loaded locking device. Specifically, the locking component plays a stabilizing role during the operation of the pressing mechanism 30. After the pressing assembly 32 finishes pressing the target sample 40, the target sample 40 is in the required position and angle. At this time, the locking component restricts the free displacement of the sliding seat 33 to ensure that the pressing position of the pressing assembly 32 does not shift, thereby maintaining the pressing accuracy.

[0051] In some embodiments, the crimping assembly 32 includes a first crimping member 321 and a second crimping member 322, which are spaced apart and located on opposite sides of the axis of the first rotating member 21. Since the first rotating member 21 and the second rotating member 22 are disposed opposite to each other, when the first crimping member 321 and the second crimping member 322 are located on opposite sides of the axis of the first rotating member 21, they are also located on opposite sides of the axis of the second rotating member 22.

[0052] Furthermore, in some other embodiments, the distance between the first crimping member 321 and the second crimping member 322 is less than the width of the target sample 40. Thus, the first crimping member 321 and the second crimping member 322 can press against both ends of the target sample 40.

[0053] This design allows the first crimping member 321 and the second crimping member 322 to apply pressure to both ends of the target sample 40, thereby achieving a crimping operation on both ends of the target sample 40. Due to the spacing between the crimping members, the middle region of the target sample 40 remains exposed. Specifically, after the target sample 40 is crimped at both ends, the middle region is exposed, becoming an object available for further analysis, testing, or processing.

[0054] Furthermore, the plane containing the bottom of the crimping assembly 32 is parallel to the surface of the base 10. For example, the surface of the base 10 is a horizontal plane, so the bottom of the crimping assembly 32 is also on a horizontal plane.

[0055] Specifically, when the pressure applying mechanism 30 applies pressure to the target sample 40, it causes the target sample 40 to rotate along with the first rotating member 21 and the second rotating member 22, eventually making the top surface of the target sample 40 flush with the bottom surface of the pressing assembly 32. Thus, when the plane containing the bottom of the pressing assembly 32 is parallel to the base 10, under the action of the pressure applying mechanism 30, the target sample 40 rotates with the first rotating member 21 and the second rotating member 22 until it is flush with the bottom surface of the pressing assembly 32, at which point the top surface of the target sample 40 is parallel to the surface of the base 10.

[0056] In some embodiments, the first pressing member 321 and the second pressing member 322 adopt a disc-shaped structure design, and the disc surfaces of the first pressing member 321 and the second pressing member 322 are placed opposite each other. Due to the special shape of the disc, the first pressing member 321 and the second pressing member 322 can occupy less space when rotating, avoiding occupying the space of the target sample 40 and reducing obstruction and interference with the target sample 40. In this way, not only can space be effectively saved, but the target sample 40 can also be ensured not to be subjected to unnecessary interference throughout the operation.

[0057] In addition, because the disc-shaped pressing component has a good streamlined shape during movement, it can rotate flexibly and adjust its position, avoiding unnecessary friction or inappropriate force during clamping, thereby reducing the risk of damage to the target sample 40.

[0058] More importantly, the disc-shaped crimping tool offers greater adaptability when dealing with target samples 40 of various shapes. Whether the target sample 40 is round, square, or other irregularly shaped, the disc design ensures the stability and effectiveness of the crimping tool. Its surface has a relatively uniform contact area with the sample, which can evenly distribute the pressure applied to the sample, thereby avoiding excessive or insufficient local pressure and ensuring uniform stress on the sample.
