Description

Technical Field

[0001] This utility model belongs to the field of PCB boards, specifically relating to a fixing structure, a PCB board adjustment mechanism, and a coupling device. Background Technology

[0002] PCB, or Printed Circuit Board, is an important electronic component. Electronic Components Item The support structure is where electronic components are electrically interconnected. carrier PCB boards are widely used in optical modules, and lenses can be mounted onto them. When mounting the lens onto the PCB board, the PCB board needs to be kept stable to ensure that the lens can be accurately installed at the coupling position and to avoid misalignment.

[0003] To secure PCB boards, clamps are often used to hold them in a stable position. However, because the edges of PCB boards are often irregular, they cannot fully conform to the clamps during clamping, resulting in poor fixation and easy displacement of the PCB board under stress. Utility Model Content

[0004] This utility model provides a fixing structure and PCB board adjustment mechanism, the purpose of which is to solve the problem of instability in fixing PCB boards in the prior art.

[0005] To achieve the above objectives, this utility model provides a fixing structure, including...

[0006] A first fixing component, wherein multiple first fixing components are arranged in a retractable manner, and the first fixing component is retractably mounted on the mounting base;

[0007] A second fixing component is disposed opposite to the first fixing component, and the first and second fixing components are used to clamp the PCB board; and

[0008] A driving component is connected to the second fixed component, and the driving component is used to drive the second fixed component to move closer to or away from the first fixed component.

[0009] This design incorporates multiple first fixing components, which are retractable. Therefore, when it is necessary to fit against the edge of the PCB board, the retraction state of the first fixing component is adjusted to bring it into contact with the edge of the PCB board. Subsequently, a second fixing component is driven by a drive assembly to move towards the first fixing component, and the second and first fixing components clamp and secure the PCB board.

[0010] Preferably, in order to fit the front, middle and rear ends of the PCB board, the first fixing component in this solution is set to three, and the first fixing component is arranged in a straight line.

[0011] This solution sets up three first fixing components to fit the front, middle and rear ends of the PCB board respectively, so that the front, middle and rear ends of the PCB board can be attached to the first fixing components, and the first fixing components will fix the PCB board better.

[0012] Preferably, in order to guide the first fixed component during extension and retraction, the mounting base of this solution is constructed with a mounting groove, the mounting groove corresponding one-to-one with the first fixed component, and the first fixed component can be extended and retractedly installed in the mounting groove.

[0013] In this design, the first fixing component is installed inside the mounting groove. Therefore, when the first fixing component extends or retracts inside the mounting groove, the mounting groove guides the first fixing component.

[0014] Preferably, in order to achieve telescopic installation of the first fixing component, the first fixing component in this solution is constructed with a slot, the mounting slot having a threaded hole inside, the slot accommodating a fastener, and the fastener passing through the slot and connecting to the threaded hole.

[0015] Preferably, to achieve vertical positioning of the left side of the PCB board, the first fixing component in this solution has a first inclined surface that tilts downwards. The first inclined surface and the top of the mounting base can vertically limit the PCB board. In this solution, the upper left side of the PCB board is restricted by the first inclined surface, and the lower left side of the PCB board is restricted by the mounting base. The first inclined surface and the mounting base cooperate to achieve vertical positioning of the left side of the PCB board, preventing the PCB board from moving up and down and making the PCB board more stable.

[0016] To achieve vertical positioning of the right side of the PCB board, the second fixing component in this design has a second inclined surface. This second inclined surface slopes downwards and is positioned above the mounting base. The second inclined surface and the top of the mounting base can vertically limit the PCB board. In this design, the upper right side of the PCB board is restricted by the second inclined surface, and the lower right side of the PCB board is restricted by the fixing base. The second inclined surface and the fixing base work together to achieve vertical positioning of the right side of the PCB board, preventing vertical movement and making the PCB board more stable.

[0017] Preferably, to achieve the movement of the second fixed component, the driving assembly of this solution includes a sliding module and a driver. The second fixed component is disposed on the sliding module, and the driver is connected to the sliding module, driving the sliding module to move. This solution provides power through the driver, which drives the sliding module to slide. When the sliding module slides, it causes the second fixed component to move, bringing the first and second fixed components closer together.

[0018] Preferably, to facilitate the operator in moving the second fixing component away from the first fixing component, thereby enabling the placement and removal of the PCB board, the driving assembly in this solution includes a manipulator connected to the sliding module. The manipulator can drive the second fixing component away from the first fixing component. When it is necessary to place or remove the PCB board, the operator can drive the manipulator to move the second fixing component away from the first fixing component, creating space between the first and second fixing components, thus facilitating the placement and removal of the PCB board.

[0019] The second aspect of this utility model discloses a PCB board adjustment mechanism, including the aforementioned fixing structure and power unit, wherein the power unit is connected to the fixing structure.

[0020] In this design, the fixing structure is used to secure the PCB board. Then, the power unit operates to adjust the PCB board's orientation, bringing it to a horizontal position. A horizontal PCB board facilitates subsequent lens coupling.

[0021] Preferably, to adjust the orientation of the PCB board, the power unit of this solution includes a rotary displacement stage, which is used to drive the fixed structure to rotate. To adjust the tilt angle of the PCB board, the power unit of this solution includes a tilt displacement stage, which is used to drive the fixed structure to tilt.

[0022] The third aspect of this utility model discloses a coupling device, including the aforementioned PCB board adjustment mechanism. By incorporating the aforementioned PCB board adjustment mechanism into the coupling device, the PCB board can be kept in a horizontal state for coupling.

[0023] The beneficial effects of this utility model are as follows: This solution provides multiple first fixing components, and the first fixing components are retractable. Therefore, when it is necessary to fit against the edge of the PCB board, the retractable state of the first fixing component is adjusted so that the first fixing component contacts the edge of the PCB board. Then, the second fixing component is driven by the driving assembly to move towards the first fixing component, and the second fixing component and the first fixing component clamp and fix the PCB board.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0032] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" are defined based on the contours of the corresponding components. Terms such as "first" and "second" used in this disclosure are for distinguishing one element from another and do not imply sequence or importance.

[0033] Example 1

[0034] The basics are as follows: Figure 1 To be continued Figure 2 As shown, a fixing structure includes a first fixing component 1, a second fixing component 2, a mounting base 3, a drive assembly 4, and a mounting plate 5.

[0035] In this embodiment, the mounting base 3 is rectangular and platform-shaped. The bottom of the mounting base 3 is mounted on the mounting plate 5, ensuring its stability. The mounting base 3 can be mounted on the mounting plate 5 by welding or by using fasteners. The top of the mounting base 3 is flat and is used to place the PCB board. The mounting base 3 has an internal cavity and a connection port on its top that communicates with the outside.

[0036] To facilitate the removal of the PCB board placed on top of the mounting base 3, the top of the mounting base 3 is provided with a through-hole 32, the top of which is open. When it is necessary to remove the PCB board, the operator inserts two fingers into the through-hole 32, which accommodates the fingers. The two fingers can then pinch the sides of the PCB board and remove it. To facilitate precise placement of the PCB, an L-shaped positioning protrusion is provided on the top left side of the mounting base 3. The L-shaped positioning protrusion contacts the top and left ends of the PCB board, achieving initial positioning of the PCB board.

[0037] In this embodiment, a mounting groove 31 is provided at the top left side of the mounting base 3. The mounting groove 31 communicates with both the receiving cavity inside the mounting base 3 and the connection port at the top of the mounting base 3. A first fixing component 1 is installed inside the mounting groove 31. The first fixing component 1 is rectangular. A first inclined surface 11 is also provided on the side of the first fixing component 1, which is inclined downward. The first inclined surface 11 can contact the side of the PCB board to limit the top of the PCB board. Preferably, three first fixing components 1 are provided, which respectively contact the front, middle and rear parts of the side of the PCB board, making the PCB board more stable. At the same time, the first fixing component 1 is telescopically installed inside the mounting groove 31. In implementation, the first fixing component 1 is provided with a slot 12, which runs through the first fixing component 1 from top to bottom. A threaded hole is provided inside the mounting groove 31. When it is necessary to move the first fixing component 1, it is only necessary to separate the bottom of the fastener from the threaded hole, so that the first fixing component 1 can telescopically move along the mounting groove 31. When it is necessary to fix the first fixing component 1, the fastener is passed through the slot 12 and the bottom of the fastener is connected to the threaded hole, so as to fix the first fixing component 1 in the mounting slot 31.

[0038] Taking one application scenario as an example: Since the edges of the PCB board are irregularly shaped, the extension state of the first fixing component 1 is adjusted so that it fits against the side of the PCB board. When the first fixing component 1 fits against the PCB board, the PCB board is fixed in place. Simultaneously, when the PCB board is placed on top of the mounting base 3, the first inclined surface 11 contacts the side of the PCB board. The top of the PCB board is restricted by the first inclined surface 11, and the bottom of the PCB board contacts the top of the mounting base 3. Therefore, both the upper and lower ends of the PCB board's side are limited, and the PCB board's side is fixed vertically, making the PCB board more stable.

[0039] In this embodiment, the second fixing component 2 is sheet-shaped, and its overall form is Z-shaped. The fixing end of the second fixing component 2 extends above the mounting base 3. The fixing end of the second fixing component 2 is provided with a second inclined surface 21, which slopes downwards. When the PCB board is placed on top of the mounting base 3, the second inclined surface 21 contacts the side of the PCB board. The top of the PCB board is restricted by the second inclined surface 21, and the bottom of the PCB board contacts the top of the mounting base 3. Through the cooperation of the second inclined surface 21 and the top of the mounting base 3, the upper and lower ends of the PCB board are limited, and the PCB board is fixed vertically.

[0040] To drive the second fixing component 2, in this embodiment, the second fixing component 2 is connected to the driving assembly 4. When the driving assembly 4 operates, it drives the second fixing component 2 to move, causing the first fixing component 1 and the second fixing component 2 to move closer to or further away from each other. When the first fixing component 1 and the second fixing component 2 move closer to each other, they clamp and fix the PCB board, keeping it stable. When the first fixing component 1 and the second fixing component 2 move further away from each other, they release the PCB board, allowing it to be removed.

[0041] The driving component 4 in this embodiment includes a sliding module 41 and a driver 42. The sliding module 41 includes a slide rail and a slider. The slide rail is mounted on the mounting plate 5, and the slider is mounted on the slide rail, allowing it to move along the slide rail. The top of the slider is fixedly connected to the second fixed component 2. When the slider moves along the slide rail, it drives the second fixed component 2 to move. The sliding module 41 guides and fixes the second fixed component 2, making its movement more precise and stable.

[0042] To facilitate the operator moving the first fixing component 1 and the second fixing component 2 away from each other when handling the PCB board, this embodiment preferably includes an operating part 43 on the slider. The operating part 43 is rod-shaped. The operating part 43 can be integrally formed with the slider, or it can be connected to the slider by welding or fasteners. The operating rod extends through the mounting base 3 to the outside of the mounting base 3. When using the device, the operator can hold the mounting base 3 with one hand and simultaneously push the operating part 43 to move the first fixing component 1 and the second fixing component 2 away from each other.

[0043] In this embodiment, the actuator 42 is a tension spring 421. One end of the tension spring 421 is fixedly connected to the slider or the second fixing component 2, and the other end of the tension spring 421 is fixedly disposed. In implementation, a mounting post can be provided on the slider or the second fixing component 2, and one end of the tension spring 421 is sleeved on the mounting post, thus fixing the first end of the tension spring 421 to the slider or the second fixing component 2. Simultaneously, a mounting post is also provided at the bottom of the mounting plate 5 or inside the mounting base 3, and the second end of the spring is sleeved on the mounting post to fix the second end of the spring. Furthermore, at least two tension springs 421 are provided, preferably two. The two tension springs 421 are respectively adapted to both sides of the slider or the second fixing component 2, ensuring that the slider or the second fixing component 2 is subjected to force on both sides, and that the second fixing component 2 is subjected to force evenly.

[0044] The following detailed description illustrates the process: When the PCB board needs to be fixed, firstly, push the operating part 43 to separate the first fixing part 1 and the second fixing part 2; then, place the PCB board on top of the mounting base 3, and make the front end and left side of the PCB board contact the L-shaped positioning protrusions respectively to achieve initial positioning of the PCB board. Next, release the operating part 43, and the first fixing part 1 and the second fixing part 2 move closer to each other under the action of the tension spring 421, clamping and fixing the PCB board. Finally, adjust the extension state of the first fixing part 1 so that it contacts the left side of the PCB board.

[0045] Example 2

[0046] The difference between this embodiment and Embodiment 1 is that the driver 42 in this embodiment is a compression spring. One end of the compression spring is connected to the sliding module 41, and the other end is connected to the column. The column is mounted on the mounting plate 5. When it is necessary to fix the PCB board between the first fixing part 1 and the second fixing part 2, the operator pushes the operating part, and the first fixing part 1 and the second fixing part 2 move away from each other, so that the PCB board can be placed between the first fixing part 1 and the second fixing part 2. At this time, the compression spring is in a compressed state. When fixing the PCB board, the operator releases the operating part, and the compression spring in the compressed state rebounds, and the first fixing part 1 and the second fixing part 2 move closer to each other, clamping the PCB board between them.

[0047] Example 3

[0048] The difference between this embodiment and Embodiment 1 is that the driving component 4 in this embodiment is a linear module or a driving cylinder. The linear module and the driving cylinder are fixedly connected to the second fixed component 2 by welding or configuring fasteners. When the linear module or the driving cylinder works, the linear module or the driving cylinder drives the second fixed component 2 to move, the second fixed component 2 moves towards the first fixed component 1, and the first fixed component 1 and the second fixed component 2 move closer to each other.

[0049] When it is necessary to fix the PCB board, the operator controls the linear module or drive cylinder to work, and the linear module or drive cylinder moves the second fixing component 2 closer to the first fixing component 1. When the first fixing component 1 and the second fixing component 2 are close to each other, the PCB board is clamped and fixed; when the first fixing component 1 and the second fixing component 2 are far apart, the PCB board is released.

[0050] Example 4

[0051] This embodiment provides a PCB board adjustment mechanism, including the fixing structure and power unit 6 described in Embodiments 1, 2, or 3, with the power unit 6 connected to the fixing structure. The power unit 6 drives the fixing structure to move, thereby adjusting the posture of the PCB board and keeping it in a horizontal state.

[0052] The power unit 6 in this embodiment includes a rotary displacement stage 61 and a tilt displacement stage 62, both of which employ existing technology. The tilt displacement stage 62 is located at the bottom of a fixed structure, which can be installed onto the tilt displacement stage 62 using fasteners; while the rotary displacement stage 61 is located at the bottom of the tilt displacement stage 62, and the rotary displacement stage 61 and the tilt displacement stage 62 are connected by fasteners.

[0053] Example 5

[0054] This embodiment provides a coupling device, including the adjustment mechanism, lens moving mechanism, adhesive application mechanism, and fixing mechanism of Embodiment 4.

[0055] In this embodiment, the adjustment mechanism fixes the PCB board so that it is in a horizontal state; the lens moving mechanism moves the lens from the lens container to the coupling position on the PCB board; the glue application mechanism is used to release glue to the coupling position on the PCB, and the glue is used to stick and fix the lens; the fixing mechanism is used to cure the glue.

[0056] The lens moving mechanism, adhesive application mechanism, and fixing mechanism in this embodiment can employ existing technologies.

[0057] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model.
