Description

Technical Field

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

[0002] A PCB, or Printed Circuit Board, is an important electronic component. It serves as the support for electronic components and the carrier for their electrical interconnections. PCBs are also widely used in optical modules, where lenses can be mounted by adhesive bonding. When mounting a lens onto a PCB, the board must remain stable to ensure the lens is precisely positioned at the coupling point.

[0003] To secure the PCB board, it is typically necessary to connect the PCB board to the BOX housing, and then fix the BOX housing, thereby securing the PCB board. For a specific fixing structure, please refer to the applicant's prior application, application number 202211053358.1, entitled "A Coupling System and Lens Assembly Method."

[0004] However, in practice, it has been found that some PCB boards are not directly connected to the BOX housing, or the shape of some BOX housings is unusual, which can cause interference with lens installation. Therefore, a fixing device that can directly adapt to the PCB board and fix it is needed. Utility Model Content

[0005] This utility model provides a PCB board mounting bracket, which aims to solve the problem of the lack of a mounting device that can directly adapt to PCB boards in the prior art.

[0006] To achieve the above objectives, this utility model provides a PCB board mounting base, including...

[0007] The base, wherein the base is provided with a first fixing part; and

[0008] A fixed structure is provided, comprising a second fixing part and a fixing power source. The first fixing part and the second fixing part are disposed opposite to each other. The fixing power source is connected to the second fixing part and is used to drive the second fixing part to move closer to or away from the first fixing part.

[0009] This design incorporates a first fixing part on the base, followed by a fixing structure. The second fixing part in the fixing structure is positioned opposite the first fixing part, and their proximity clamps the PCB board in place. Once clamped, the PCB board is in a stable state, thus achieving its fixation.

[0010] Preferably, the PC board is fixed when the second fixing part moves closer to the first fixing part; the PC board is released when the second fixing part moves away from the first fixing part. Therefore, in order to make the movement of the second fixing part more precise and stable, the fixing power in this solution includes a sliding seat, and the second fixing part is disposed on the sliding seat.

[0011] This design connects the sliding base to the second fixing part. When the sliding base slides, it drives the second fixing part to slide as well. Because the second fixing part is moved by the sliding base, its movement is more precise and stable, ensuring that the first and second fixing parts accurately clamp the PCB board.

[0012] Preferably, in order to provide the moving power for the second fixing part, the fixing power of this solution includes a power component, which is connected to the sliding seat. The power component drives the sliding seat to move, so that the second fixing part moves closer to or away from the first fixing part.

[0013] In this design, the power unit is connected to the sliding base. The power unit drives the sliding base to slide, which in turn moves the second fixing part closer to the first fixing part. The first and second fixing parts clamp and fix the PCB board. Simultaneously, the power unit provides the fixing power to the second fixing part, ensuring that the second fixing part can stably cooperate with the first fixing part to clamp the PCB board.

[0014] Preferably, in this first embodiment, the power component is a tension spring.

[0015] Alternatively, in this second embodiment, the preferred power component is a compression spring.

[0016] Preferably, in order to facilitate the operator's operation and move the first fixing part and the second fixing part away from each other, the fixing power of this solution includes a control part, which is connected to the sliding seat or the second fixing part, and the control part is used to drive the second fixing part away from the first fixing part.

[0017] This solution includes an operating unit for user operation. By pushing the operating unit, the first fixing part and the second fixing part can be moved away from each other, making it easier to place the PCB board between the first fixing part and the second fixing part, or to remove the PCB board from between the first fixing part and the second fixing part.

[0018] Preferably, in order to achieve the initial positioning of the PCB board, the base of this solution is provided with a positioning protrusion, the positioning protrusion is L-shaped, and the positioning protrusion is used to contact the top and side of the PCB board.

[0019] This design incorporates positioning protrusions on the top and sides of the PCB board to achieve initial positioning. After the PCB board is initially positioned, the first and second fixing parts are brought closer together to clamp and fix the PCB board.

[0020] Preferably, to achieve upper and lower limits on the left side of the PCB board, the first fixing part in this solution has a first inclined surface that tilts downwards and is used to contact the side of the PCB board. In this solution, the upper left side of the PCB board is limited by the first inclined surface, and the lower left side of the PCB board is limited by the base. The first inclined surface and the base cooperate to achieve upper and lower limits on the left side of the PCB board, preventing the PCB board from moving up and down and making the PCB board more stable.

[0021] To achieve vertical positioning of the right side of the PCB board, the second fixing part in this design has a second inclined surface that slopes downwards and contacts the side of 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 is restricted by the base. The second inclined surface and the 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.

[0022] The second aspect of this utility model discloses an adjustment mechanism, including the aforementioned PCB board fixing base and a moving component, wherein the moving component is connected to the PCB board fixing base.

[0023] In this design, the PCB board holder is used to fix the PCB board in place. Then, the moving component operates, adjusting the PCB board's orientation until it is horizontal. A horizontal PCB board facilitates subsequent lens coupling.

[0024] Preferably, in order to adjust the orientation of the PCB board, the moving component of this solution includes a rotary displacement stage, which is used to drive the PCB board fixing seat to rotate.

[0025] In order to adjust the tilt angle of the PCB board, the moving component of this solution includes a tilt displacement stage, which is used to tilt the PCB board fixing base.

[0026] The third aspect of this utility model discloses a coupling device, including the aforementioned adjustment mechanism. By incorporating the adjustment mechanism into the coupling device, the PCB board can be kept in a horizontal state for coupling.

[0027] The beneficial effects of this utility model are as follows: This solution provides a first fixing part on the base, and then a fixing structure is provided in conjunction with the base. The second fixing part in the fixing structure is arranged opposite to the first fixing part, and the first fixing part and the second fixing part are close to each other, thereby clamping and fixing the PCB board. After the first fixing part and the second fixing part clamp the PCB board, the PCB board is in a stable state, thus achieving the fixing of the PCB board and solving the shortcomings of the prior art.

Detailed Implementation

[0037] 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.

[0038] 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.

[0039] Example 1

[0040] The basics are as follows: Figure 1 To be continued Figure 2 As shown, a PCB board mounting bracket includes a base 1, a fixing structure 2, and a mounting component. The base 1 and the fixing structure 2 are mounted on top of the mounting component, which provides a mounting base for the base 1 and the fixing structure 2. The mounting component can be a mounting plate 3 or a mounting platform. The base 1 and the fixing structure 2 can be fixed to the mounting component by welding or by configuring fasteners.

[0041] In this embodiment, the base 1 is rectangular. The top of the base 1 is flat and is used to place the PCB board 4. An L-shaped positioning protrusion 11 is provided on the left side of the top of the base 1. The L-shaped positioning protrusion 11 contacts the top and left ends of the PCB board 4, achieving initial positioning of the PCB board 4. The interior of the base 1 is hollow, and the top of the base 1 also has a connection port communicating with the outside.

[0042] To facilitate the removal of the PCB board 4 placed on top of the base 1, the top of the base 1 is provided with a retrieval opening that extends through the base 1, with the top of the retrieval opening being open. When it is necessary to remove the PCB board 4, the operator inserts two fingers into the retrieval opening, which accommodates the fingers. The two fingers can then pinch the two sides of the PCB board 4, thereby removing the PCB board 4.

[0043] To secure the PCB board 4, this embodiment provides a mounting groove at the top left side of the base 1. The mounting groove communicates with both the interior of the base 1 and the connection port at the top of the base 1. A first fixing part 12, which is rectangular in shape, is installed inside the mounting groove. The side of the first fixing part 12 is also provided with a first inclined surface 121, which slopes downwards. The first inclined surface 121 can contact the side of the PCB board 4, thereby limiting the top edge of the PCB board 4.

[0044] Taking one application scenario as an example: when PCB board 4 is placed on top of base 1, the first inclined surface 121 contacts the side of PCB board 4. The top of PCB board 4 is restricted by the first inclined surface 121, and the bottom of PCB board 4 contacts the top of base 1. Therefore, the upper and lower ends of the side of PCB board 4 are limited, and the side of PCB board 4 is fixed from top to bottom, making PCB board 4 more stable.

[0045] In this embodiment, multiple first fixing parts 12 are provided, preferably three. These three first fixing parts 12 respectively contact the front, middle, and rear sides of the PCB board 4, making the PCB board 4 more stable. Simultaneously, the first fixing parts 12 are telescopically installed inside the mounting groove. In implementation, the first fixing part 12 is provided with a slot 122 that extends from top to bottom through the first fixing part 12. The mounting groove has a threaded hole inside. When it is necessary to move the first fixing part 12, simply separate the bottom of the bolt from the threaded hole, allowing the first fixing part 12 to telescopically extend along the mounting groove, thus moving the first fixing part 12. When it is necessary to fix the first fixing part 12, pass the bolt through the slot 122, with the bottom of the bolt connecting to the threaded hole, thereby fixing the first fixing part 12 inside the mounting groove.

[0046] It is understandable that when PCB boards 4 of different shapes need to be fixed, the extension state of the first fixing part 12 is adjusted so that the first fixing part 12 fits against the side of the PCB board 4. After the first fixing part 12 fits against the PCB board 4, the PCB board 4 is fixed.

[0047] The fixing structure 2 in this embodiment includes a second fixing part 21 and a fixing power 22. The second fixing part 21 is plate-shaped and has an overall Z-shape. The top of the second fixing part 21 is used to contact the side of the PCB board 4. The second fixing part 21 is connected to the fixing power 22. When the fixing power 22 is working, it drives the second fixing part 21 to move, so that the first fixing part 12 and the second fixing part 21 move closer or further apart. When the first fixing part 12 and the second fixing part 21 move closer together, they clamp and fix the PCB board 4, keeping the PCB board 4 stable; when the first fixing part 12 and the second fixing part 21 move further apart, they release the PCB board 4.

[0048] To ensure a more stable fixation of the PCB board 4, this embodiment provides a second inclined surface 211 at the top of the second fixing part 21, with the second inclined surface 211 tilting downwards. When the PCB board 4 is placed on top of the base 1, the first inclined surface 121 contacts the side of the PCB board 4. The top of the PCB board 4 is restricted by the second inclined surface 211, and the bottom of the PCB board 4 contacts the top of the base 1. The upper and lower ends of the side of the PCB board 4 are limited, thus fixing the side of the PCB board 4 vertically.

[0049] The fixed power source 22 in this embodiment includes a sliding seat 221 and a power component 222. The sliding seat 221 is preferably a sliding module, comprising a slide rail and a slider. The slide rail is mounted on the mounting plate 3, 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 part 21. When the slider moves along the slide rail, it drives the second fixed part 21 to move. The sliding seat 221 guides and fixes the second fixed part 21, resulting in more precise and stable movement of the second fixed part 21.

[0050] Meanwhile, in order to accommodate the sliding seat 221, a receiving opening is provided on the side of the base 1, which communicates with the interior of the base 1. The front end of the sliding seat 221 can extend into the interior of the base 1 through the receiving opening, thus avoiding interference between the base 1 and the sliding seat 221.

[0051] To facilitate the operator moving the first fixing part 12 and the second fixing part 21 away from each other when picking up and placing the PCB board 4, this embodiment preferably provides an operating part on the slider, which is rod-shaped. The operating part 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 base 1 to the outside of the base 1. When using the device, the operator can hold the base 1 with one hand and push the operating part to move the first fixing part 12 and the second fixing part 21 away from each other.

[0052] In this embodiment, the power component 222 is a tension spring. One end of the tension spring is fixedly connected to the slider or the second fixing part 21, and the other end of the tension spring is fixedly disposed. In implementation, a mounting post can be provided on the slider or the second fixing part 21, and one end of the tension spring can be sleeved on the mounting post, so that the first end of the tension spring is fixedly connected to the slider or the second fixing part 21; at the same time, a mounting post can also be provided at the bottom of the mounting plate 3 or inside the base 1, and the second end of the spring can be sleeved on the mounting post to fix the second end of the spring.

[0053] In this embodiment, at least two tension springs are preferably provided, and more preferably two. The two tension springs are respectively adapted to both sides of the slider or the second fixing part 21. Through the two tension springs, it is ensured that the slider or the second fixing part 21 is subjected to force on both sides, and the second fixing part 21 can be subjected to force evenly.

[0054] The following detailed description illustrates the specific implementation method: When it is necessary to fix the PCB board 4, firstly, push the operating part to separate the first fixing part 12 and the second fixing part 21; then, place the PCB board 4 on top of the base 1, and make the front end and left side of the PCB board 4 contact the L-shaped positioning protrusion 11 respectively to achieve initial positioning of the PCB board 4. Then, release the operating part, and the first fixing part 12 and the second fixing part 21 move closer to each other under the action of the tension spring, clamping and fixing the PCB board 4. Finally, adjust the extension state of the first fixing part 12 so that the first fixing part 12 contacts the left side of the PCB board 4.

[0055] Example 2

[0056] The difference between this embodiment and Embodiment 1 is that, as Figure 7 As shown, in this embodiment, the power component 222 is a compression spring. One end of the compression spring is connected to the sliding seat 221, and the other end is connected to the column. The column is mounted on the mounting plate 3. When it is necessary to fix the PCB board 4 between the first fixing part 12 and the second fixing part 21, the operator pushes the operating part 223, and the first fixing part 12 and the second fixing part 21 move away from each other, so that the PCB board 4 can be placed between the first fixing part 12 and the second fixing part 21. At this time, the compression spring is in a compressed state. When fixing the PCB board 4, the operator releases the operating part 223, and the compression spring in the compressed state rebounds, and the first fixing part 12 and the second fixing part 21 move closer to each other, clamping the PCB board 4 between them.

[0057] Example 3

[0058] The difference between this embodiment and Embodiment 1 is that the fixing power 22 in this embodiment is a linear power source. The linear power source is a linear module or a drive cylinder. The linear module and drive cylinder are fixedly connected to the second fixing part 21 by welding or configuring fasteners. When the linear power source is working, it drives the second fixing part 21 to move, and the second fixing part 21 moves toward the first fixing part 12, and the first fixing part 12 and the second fixing part 21 move closer to each other.

[0059] When it is necessary to fix the PCB board 4, the operator controls the linear motor to move the second fixing part 21 closer to the first fixing part 12. When the first fixing part 12 and the second fixing part 21 approach each other, the PCB board 4 is clamped and fixed; when the first fixing part 12 and the second fixing part 21 move away from each other, the PCB board 4 is released.

[0060] Example 4

[0061] This embodiment provides an adjustment mechanism, including a PCB board 4 fixing base and a moving component 5 as described in Embodiments 1, 2, or 3. The moving component 5 is connected to the PCB board 4 fixing base. The moving component 5 drives the PCB board 4 fixing base to move, thereby adjusting the posture of the PCB board 4, and keeping the PCB board 4 in a horizontal state.

[0062] The moving component 5 in this embodiment includes a rotary displacement stage 52 and a tilt displacement stage 51, both of which employ existing technology. The tilt displacement stage 51 is disposed at the bottom of the PCB board 4 mounting base, which can be mounted to the tilt displacement stage 51 using fasteners; while the rotary displacement stage 52 is disposed at the bottom of the tilt displacement stage 51, and the rotary displacement stage 52 and the tilt displacement stage 51 are connected by fasteners.

[0063] Example 5

[0064] This embodiment provides a coupling device, including the adjustment mechanism, lens moving mechanism, adhesive application mechanism, and fixing mechanism of Embodiment 4.

[0065] In this embodiment, the adjustment mechanism fixes the PCB board 4 so that the PCB board 4 is in a horizontal state; the lens moving mechanism moves the lens from the lens container to the coupling position of the PCB board 4; 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.

[0066] The lens moving mechanism, adhesive application mechanism, and fixing mechanism in this embodiment can employ existing technologies.

[0067] 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.
