Description

Technical Field

[0001] This application relates to the field of semiconductor technology, and more specifically to an angle adjustment mechanism that can be used in a compact space. Background Technology

[0002] When photographing alignment marks (such as in a microscope), the light source needs to illuminate at a specific angle. The actual imaging effect is affected by multiple factors, including the parallelism and brightness of the light source, the shooting angle, and the illumination distance. In existing technologies, the light source cannot illuminate at the required specific angle when photographing alignment marks. Furthermore, due to the small working distance of microscope imaging objectives, existing light source adjustment structures often cannot be accommodated, ultimately resulting in poor imaging quality. Therefore, an angle adjustment mechanism suitable for use in compact spaces is proposed to solve the above problems. Utility Model Content

The corner housing has an upper end of its side wall rotatably connected to a rotating hole, and hollow shafts are respectively provided in the upper and lower side walls. The corner housing has a sliding shaft cavity with an opening facing a fixed plate. The sliding shaft cavity is fixedly connected to and communicates with two hollow shafts. The lower end of the limiting slide groove is inclined towards the corner housing. A sliding shaft component is disposed in the sliding shaft cavity, with its two ends respectively disposed in the two hollow shafts. The sliding shaft component includes a stud and a sliding shaft. The stud is disposed at one end of the sliding shaft and threadedly connected to one of the hollow shafts. The two ends of the sliding shaft are respectively disposed in… The two hollow shafts have internal threads on their inner sides, allowing the stud to be fed helically along the hollow shaft. One end of the sliding shaft is tightly abutted against one side of the stud, while the other end can slide axially relative to the hollow shaft. As the stud is fed helically, the sliding shaft slides axially along the hollow shaft. The sliding shaft has an ear plate at its center, with one end of the ear plate passing through the opening of the sliding shaft cavity and positioned within a limiting groove. The ear plate can slide and rotate relative to the limiting groove. Preload springs are provided between the ear plate and the two hollow shafts, and both preload springs are sleeved on the sliding shaft.

[0005] According to the aforementioned embodiment of the first aspect of this application, the outer wall of the sliding shaft is provided with a second threaded hole, and the other end of the ear plate is provided with a through hole and a third threaded hole.

The sliding shaft passes through the through hole so that the second threaded hole and the third threaded hole are aligned. The sliding shaft and the ear plate are detachably connected through the second threaded hole and the third threaded hole.

[0006] According to any of the foregoing embodiments of the first aspect of this application, the end face of one end of the ear plate is provided with two rotating protrusions, and a rotating shaft is provided between the two rotating protrusions. The rotating shaft is slidably disposed in the limiting groove.

[0007] According to any of the foregoing embodiments of the first aspect of this application, the ear plate is perpendicular to the axis of the sliding shaft, and one end of the ear plate is bent downward relative to the other end of the ear plate.

[0008] According to any of the foregoing embodiments of the first aspect of this application, a bushing is provided between the rotating shaft and the limiting slide groove, the rotating shaft passes through the bushing, and one end of the rotating shaft is threadedly connected to a nut, one side of the nut abuts against the side end of the bushing, and there is a gap between the outer wall of the bushing and the limiting slide groove.

[0009] According to any of the foregoing embodiments of the first aspect of this application, the upper and lower sidewalls of the corner housing are provided with first threaded holes, and the two hollow shafts are respectively threaded to the two first threaded holes.

Detailed Implementation

[0015] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0016] Firstly, such as Figure 1 As shown in the figure, this application embodiment provides an angle adjustment mechanism that can be used in a compact space, mainly including a fixed plate 100, an angle housing 200, and a sliding shaft 400. This device is mainly used for adjusting the angle of a light source.

[0017] In this embodiment, the fixing plate 100 is provided with a limiting slide groove 110 and a rotating hole 120. Both the limiting slide groove 110 and the rotating hole 120 penetrate through the two side walls of the fixing plate 100, and the limiting slide groove 110 is located below the rotating hole 120. Specifically, the rotating hole 120 is perpendicular to the surface of the fixing plate 100 and passes through the two side walls of the fixing plate 100. A semi-circular protrusion extends from the upper surface of the side end of the fixing plate 100 in the direction that the end face is facing. The rotating hole 120 is located on the semi-circular protrusion, and the axial direction of the rotating hole 120 coincides with the axial direction of the semi-circular protrusion. The lower side of the end face of the side end of the fixing plate 100 is inclined in the direction that the end face is facing, and the limiting slide groove 110 is opened at this position. The inclination direction of the limiting slide groove 110 is consistent with the inclination direction of the end face of the side end of the fixing plate 100.

[0018] In this embodiment, as Figures 1-4 As shown, the upper end of the side wall of the corner housing 200 is provided with two corner protrusions 230, and a rotating shaft 240 is provided between the two corner protrusions 230. The rotating shaft 240 is adapted to the rotating hole 120, so that the top of the side wall of the corner housing rotates relative to the fixed plate 100, thereby causing the upper side of the corner housing 200 to rotate relative to the side end of the fixed plate 100.

[0019] In this embodiment, as Figure 3 As shown, the other end of the fixing plate 100 is provided with a side plate 900. The surface of the side plate 900 is perpendicular to the end face of the other side of the fixing plate 100, thereby providing installation space for the installation and fixing of the fixing plate 100. Specifically, the fixing plate 100 and the side plate 900 are connected to each other to form a T-shaped plate.

[0020] The corner housing 200 can adopt a cylindrical or rectangular structure. For ease of description, in this embodiment, the corner housing 200 adopts a rectangular structure. The light source 3000 is disposed on the surface of the lower end of the corner housing 200, so that when the corner housing 200 rotates, it drives the light source 3000 to rotate as well.

[0021] One embodiment provides a light source 3000 mounted on the lower side of a corner housing 200, such as... Figure 7 As shown, the light source 3000 is disposed on the surface of the lower end of the corner housing 200. When the corner housing 200 rotates, it can drive the light source 3000 to rotate.

[0022] The upper end of the side wall of the corner housing 200 is rotatably connected to the rotating hole 120, and hollow shafts 300 are respectively provided in the upper and lower side walls. Specifically, the axial directions of the two hollow shafts 300 are perpendicular to the upper and lower side walls of the corner housing 200, respectively. The corner housing 200 is provided with a sliding shaft cavity 210, which is connected to the two hollow shafts 300. The sliding shaft cavity 210 has an opening facing the fixed plate 100, and the opening is at the same height as the sliding shaft cavity 210. The lower end of the limiting slide groove 110 is inclined towards the corner housing 200, and the other end of the limiting slide groove 110 is away from the corner housing 200.

[0023] In this embodiment, as Figure 1 and Figure 4 As shown, the sliding shaft 400 is disposed in the sliding shaft cavity 210, and its two ends are respectively disposed in two hollow shafts 300. Specifically, one of the hollow shafts 300 is provided with an internal thread, one end of the sliding shaft 400 is threadedly connected to one of the hollow shafts 300, and the other end of the sliding shaft 400 is disposed in the other hollow shaft 300. The hollow part of the other hollow shaft 300 is adapted to the other end of the sliding shaft 400 so that the other end of the sliding shaft 400 can slide axially relative to the other hollow shaft 300. The sliding shaft 400 is coaxially disposed with both hollow shafts 300, thereby allowing the sliding shaft 400 to be axially displaced relative to the hollow shafts 300.

[0024] In this embodiment, as Figure 1 , Figure 5 and Figure 6As shown, the sliding shaft component 400 has an ear plate 500 at its center, which is connected to the sliding shaft component 400. One end of the ear plate 500 passes through the opening of the sliding shaft cavity 210 and is disposed within the limiting slide groove 110. One end of the ear plate 500 can slide and rotate relative to the limiting slide groove 110. Specifically, the end face of one end of the ear plate 500 has two rotating protrusions 530, which are respectively disposed on both sides of the limiting slide groove 110 of the fixed plate 100. A rotating shaft 1000 is disposed between the two rotating protrusions 530 and is slidably disposed within the limiting slide groove 110. A bushing 2000 is disposed between the rotating shaft 1000 and the limiting slide groove 110, and the rotating shaft 1000 passes through the bushing 2000. The shaft 1000 has an external thread. After passing through the bushing 2000, one end of the shaft 1000 is connected to the nut 800, and the threaded sidewall abuts against the side end of the bushing 2000. The other end of the shaft 1000 has a limiting end 1100, and the sidewall of the limiting end 1100 abuts against the other side end of the bushing 2000. This allows the shaft 1000 and the bushing 2000 to be detachably connected. When the bushing 2000 slides and rotates relative to the limiting slide groove 110, it can drive the shaft 1000 to rotate and move, thereby driving the ear plate 500 to rotate and move. There is a gap between the bushing 2000 and the limiting slide groove 110, which provides a local degree of freedom for one end of the ear plate 500, ensuring that the one end of the ear plate 500 slides relatively smoothly relative to the limiting slide groove 110.

[0025] In this embodiment, as Figure 1 , Figure 5 and Figure 6 As shown, the outer wall of the sliding shaft 400 in the circumferential direction is provided with a second threaded hole 421, and the other end of the ear plate 500 is provided with a through hole 510 and a third threaded hole 520. The third thread is provided on the outer wall of the ear plate 500 in the circumferential direction and is located at one end of the limiting slide groove 110 away from the ear plate 500. The through hole 510 is adapted to the sliding shaft 400, so that the sliding shaft 400 can pass through the through hole 510. When the sliding shaft 400 passes through the through hole 510, the second threaded hole 421 and the third threaded hole 520 are aligned. The sliding shaft 400 and the ear plate 500 are connected by a connecting bolt 700, so that the sliding shaft 400 and the ear plate 500 are bolted together through the second threaded hole 421 and the third threaded hole 520, thereby making the sliding shaft 400 and the ear plate 500 detachably connected, and the sliding shaft 400 can drive the ear plate 500 to move.

[0026] In this embodiment, as Figures 1-3As shown, a preload spring 600 is provided between the ear plate 500 and the two hollow shafts 300. The two preload springs 600 are sleeved on the sliding shaft 400. Specifically, the two preload springs 600 are in a compressed state. One end of the two preload springs 600 abuts against the upper and lower side walls of the other end of the ear plate 500, respectively, and the other end of the two preload springs 600 abuts against the lower ends of the two hollow shafts 300, thereby fixing the sliding shaft 400 and the ear plate 500 at its center with the two preload springs 600, thus making the device transmission stable and the positioning reliable.

[0027] In some embodiments, such as Figure 5 and Figure 6 As shown, the ear plate 500 is perpendicular to the axis of the sliding shaft 400, and one end of the ear plate 500 is bent downward relative to the other end of the ear plate 500, so that the bushing 2000 at one end of the ear plate 500 can move more smoothly, and is relatively stable when stationary.

[0028] In some embodiments, as shown in the figure, the sliding shaft 400 includes a stud 410 and a sliding shaft 420. The stud 410 is disposed at one end of the sliding shaft 420 and abuts against one end of the sliding shaft 420. The stud 410 is threadedly connected to one of the hollow shafts 300. The two ends of the sliding shaft 420 are respectively disposed in the two hollow shafts 300. The lower side of the internal thread of one of the hollow shafts 300 has a hollow portion that is adapted to one end of the sliding shaft 420. The other hollow shaft 300 is adapted to the other end of the sliding shaft 420. Thus, by rotating the stud 410 and the action of the preload spring 600, the axial displacement of the sliding shaft 420 along the hollow shaft 300 can be controlled, thereby making the displacement of the sliding shaft 420 more convenient.

[0029] In this embodiment, the upper surface of the stud 410 is provided with a strip groove, so that the stud 410 can be rotated by tools such as screwdrivers, making the rotation of the stud 410 relatively easy.

[0030] In this embodiment, as Figure 1 , Figure 5 and Figure 6 As shown, the second threaded hole 421 is provided on the outer wall in the central circumferential direction, and the through hole 510 of the ear plate 500 is adapted to the slide shaft 420, so that the slide shaft 420 passes through the through hole 510, thereby aligning the third threaded hole 520 of the ear plate 500 with the third threaded hole 520 of the slide shaft 420, so that the slide shaft 420 and the ear plate 500 are detachably connected, and the slide shaft 420 can drive the ear plate 500 to move axially along the hollow shaft 300. The two preload springs 600 are both sleeved on the outside of the slide shaft 420.

[0031] In some embodiments, such as Figures 1-4As shown, the upper and lower sidewalls of the corner housing 200 are provided with first threaded holes 220. Two hollow shafts 300 are threadedly connected to the two first threaded holes 220 respectively. The lower end of the hollow shaft 300 is located in the sliding shaft cavity 210, and its diameter is smaller than the diameter of the shaft body of the hollow shaft 300 located in the wall of the corner housing 200. Two preload springs 600 are respectively sleeved on the outer wall of the shaft body of the two hollow shafts 300 located in the sliding shaft cavity 210, and abut against the lower end of the shaft body of the two sliding shaft cavities 210 located in the wall of the corner housing 200. This allows the preload force of the preload springs 600 to be adjusted by rotating the two hollow shafts 300, so that the preload force is moderate and matches the displacement of the sliding shaft 420, thereby stabilizing the sliding shaft 420 and making the whole device stable. In addition, it can also eliminate the connection gap between the mechanisms, thereby ensuring the transmission accuracy and providing the mechanism with the return driving force.

[0032] In some embodiments, such as Figures 1-2 As shown, the slide shaft cavity 210 is also provided with another opening. The two openings are arranged opposite to each other, so that the ear plate 500 and the slide shaft 420 can be disassembled through the position of the other opening, and the compression of the preload spring 600 and the displacement of the slide shaft 420 can be observed through the other opening, so as to adjust the preload spring 600 and the slide shaft 420.

[0033] According to the above embodiments, the working principle of this device is as follows: Rotate the two hollow shafts 300 to their preset positions. The lower ends of the larger diameter shafts of the two hollow shafts 300 abut against the two preload springs 600, thereby adjusting the preload force. The two preload springs 600 are in a compressed state.

[0034] Subsequently, if the stud 410 is screwed in, the stud 410 screws into the hollow shaft 300, the stud 410 presses against the end face of the sliding shaft 420, and the sliding shaft 420 moves downward along the hollow shaft 300, thereby driving the ear plate 500 to move axially along the hollow shaft 300. This causes the other end of the ear plate 500 to drive the rotating shaft 1000 and the bushing 2000 to move downward along the limiting slide groove 110. At the same time, the preload spring 600 on the upper side of the ear plate 500 extends, and the preload spring 600 on the lower side of the ear plate 500 is compressed. At this time, the ear plate 500 pushes the sliding shaft 420, thereby causing the corner housing 200 to drive the rotating shaft 240 to rotate clockwise relative to the rotating hole 120 of the fixed plate 100. Since the preload spring 600 is always in a compressed state, the connection gap between the mechanisms is eliminated, thereby ensuring the transmission accuracy and providing the mechanism with the return driving force.

[0035] If the stud 410 is unscrewed, the stud 410 disengages from the end face of the sliding shaft 420. Due to the inconsistent compression of the preload springs 600 on both sides of the ear plate 500, the preload spring 600 on the lower side of the ear plate 500 extends, while the preload spring 600 on the upper side of the ear plate 500 is compressed under the action of the ear plate 500. Under the action of the preload spring 600, the preload spring 600 on the lower side of the ear plate 500 pushes the ear plate 500 to move upward along the axial direction of the hollow shaft 300. This causes the ear plate 500 to drive the rotating shaft 1000 and the bushing 2000 to move upward along the limiting groove. Consequently, the corner housing 200 drives the rotating shaft 240 to rotate counterclockwise relative to the rotating hole 120 of the fixed plate 100, thereby adjusting the angle of the light source.

[0036] In this embodiment, the adjustment accuracy is high, and the mechanism has a compact structure, is easy to assemble and adjust, and has a high space utilization rate, thus enabling the device to be used in scenarios with narrow space and a wide adjustment range.
