Description

Technical Field

[0001] This utility model belongs to the technical field of main control board fixing device, and in particular relates to a main control board mounting and fixing device. Background Technology

[0002] In the field of electronic equipment manufacturing, the main control board, as a core component, exhibits a trend of diversification in its specifications and models. Different customers and application scenarios have different requirements for the size, shape, and interface layout of the main control board. However, existing main control board mounting devices often lack sufficient adaptability in their design and can usually only be used for assembling main control boards of specific specifications. When it is necessary to install main control boards of different sizes or shapes, it is often necessary to replace the entire mounting device, which not only increases production costs but also reduces production efficiency.

[0003] Currently, most mainstream fixing devices use rigid clamping, which has significant drawbacks. Due to the uneven distribution of rigid clamping force, it is very easy to cause local stress concentration on the main control board, which can lead to damage to the clamping part or deformation of the main control board as a whole.

[0004] Furthermore, in scenarios involving frequent assembly and disassembly, the excessive clamping force applied by rigid clamping will further increase the risk of damage to the main control board, seriously affecting its service life and performance stability. Moreover, in the face of complex and ever-changing working environments, a single fixed rigid clamping mode lacks flexibility and adaptability, making it difficult to meet diverse usage needs. Utility Model Content

[0005] This utility model provides a main control board mounting and fixing device, which aims to solve the problems of existing rigid clamping and fixing devices, such as uneven force distribution leading to local stress concentration on the main control board, clamping damage and deformation, high frequency of installation and disassembly easily increasing the risk of board damage and affecting life performance due to excessive clamping force, and single mode being difficult to adapt to complex environments and unable to meet diverse needs.

[0006] This utility model is implemented as follows: a main control board mounting and fixing device includes a fixing base, the top of which is equipped with an adjustment platform that can rotate around a vertical axis via a rotary bearing;

[0007] A set of mounting shafts are symmetrically distributed on the side of the adjustment platform;

[0008] The two mounting shafts are rotatably fitted together by the same assembly table;

[0009] Side plates are provided on all four sides of the upper surface of the assembly table;

[0010] An electric push rod is fixedly connected to the inner side of each side plate in the horizontal direction, and the piston rod end of the electric push rod is connected to a flexible clamping assembly.

[0011] The flexible clamping assembly includes:

[0012] A fixed plate is fixedly connected to the electric push rod piston rod. At least two elastic columns are evenly arranged circumferentially on the inner side of the fixed plate. The ends of each pair of elastic columns are connected to the same flexible gasket, and a pressure sensor is embedded between the fixed plate and the flexible gasket.

[0013] Preferably, the top surface of the adjusting plate is provided with an assembly groove, and a lead screw is provided in the assembly groove. The two ends of the lead screw are rotatably connected to the end side of the groove through thrust bearings. An adjusting block is threaded on the lead screw. The bottom of the adjusting block is slidably engaged with the bottom surface of the groove through a linear bearing. A U-shaped assembly seat is fixedly connected to the top.

[0014] Preferably, an electric telescopic rod is installed inside the assembly base via a fixed shaft, and the output end of the electric telescopic rod is connected to the bottom side of the assembly table via a universal ball hinge.

[0015] Preferably, the end of the lead screw is flexibly connected to the output shaft of the stepper motor via a flexible coupling.

[0016] Preferably, a servo motor is provided on the top side of the fixed base, and the output end of the servo motor is fixedly connected to the end of the adjustment table through a flexible coupling.

[0017] Preferably, the surface of the flexible pad is provided with anti-slip texture, and the anti-slip texture is adapted to the edge shape of the main control board.

[0018] Preferably, the assembly table is provided with a sliding guide groove assembly, which includes linear guide grooves orthogonally distributed along the X / Y axes of the assembly table. Each linear guide groove is provided with a slider, and the slider is connected to the corresponding fixed plate.

[0019] Preferably, the outer edge of the side of the assembly table is provided with an annular stop bar that is higher than its horizontal height.

[0020] Compared with the prior art, the embodiments of this application have the following main advantages:

[0021] Firstly, this device possesses high adaptability and flexibility, fully meeting the processing requirements of fastening pads for main control boards of different specifications. Its assembly table has adjustable angle and tilt angle functions. During the assembly process, the angle and position of the assembly table can be precisely and flexibly adjusted according to actual production needs. This feature enables the device to easily adapt to various assembly tasks and accurately adapt to the installation requirements of main control boards and other components in diverse scenarios, significantly improving the flexibility and versatility of assembly operations and providing a strong guarantee for efficient and high-quality main control board assembly production.

[0022] Secondly, this device is equipped with a flexible clamping component inside the fixed plate. In practical applications, when the main control board is clamped, the flexible contact surface first contacts the edge of the main control board. Its soft material can evenly distribute the initial contact pressure and avoid local stress concentration. As the clamping action proceeds, the flexible clamping component undergoes elastic deformation and automatically adjusts the clamping force according to the reaction force of the main control board. While providing sufficient clamping force to ensure the stability of the main control board position, it uses elastic potential energy to absorb excessive clamping force and prevent the main control board from being damaged due to excessive pressure.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0031] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0032] This utility model embodiment provides a main control board mounting and fixing device, such as... Figure 1-6 As shown, it includes a fixed base 1, on the top of which an adjustment platform 3 that can rotate about a vertical axis is mounted via a rotating shaft 2;

[0033] A set of mounting shafts 4 are symmetrically distributed on the side of the adjustment platform 3;

[0034] The two mounting shafts 4 are rotatably fitted together by the same mounting table 5;

[0035] Side plates 6 are provided on all four sides of the upper surface of the assembly table 5;

[0036] An electric push rod 7 is fixedly connected to the inner side of each side plate 6 in the horizontal direction, and the piston rod end of the electric push rod 7 is connected to a flexible clamping assembly.

[0037] The flexible clamping assembly includes:

[0038] The fixing plate 8 is fixedly connected to the piston rod of the electric push rod 7. At least two elastic columns 9 are evenly arranged in the circumferential direction on the inner side of the fixing plate 8. The end of each pair of elastic columns 9 is connected to the same flexible gasket 10, and a pressure sensor 11 is embedded between the fixing plate 8 and the flexible gasket 10.

[0039] It should be noted that existing rigid clamping and fixing devices suffer from uneven force distribution, leading to localized stress concentration on the main control board, clamping damage and deformation. Frequent assembly and disassembly can easily increase the risk of board damage and affect lifespan performance due to excessive clamping force. Furthermore, a single mode is difficult to adapt to complex environments and cannot meet diverse needs. This solution significantly improves the efficiency and quality of main control board assembly operations through its high adaptability and flexibility. The adjustable angle and position of the assembly table 5 enable it to accurately adapt to the installation requirements of main control boards of different specifications, easily handling diverse assembly scenarios. At the same time, the flexible clamping components inside the fixing plate 8 can evenly distribute the initial contact pressure and automatically adjust the clamping force when clamping the main control board, ensuring the stability of the main control board position and preventing damage due to excessive pressure, effectively guaranteeing the efficiency of the assembly process and the safety of the main control board.

[0040] Specifically, in this embodiment, the solution mainly includes a fixed base 1, on which the main control board is placed on the assembly table 5. The rotating shaft 2 at the bottom of the adjustment table 3 is used to rotate the main control board around the vertical axis to adjust it to a suitable angle. Then, two mounting shafts 4 are used to finely adjust the angle of the assembly table 5 so that the main control board is in a suitable installation position. After that, the piston rods of the electric push rods 7 on the inner side of each side plate 6 extend and drive the flexible clamping components at their ends to move toward the main control board. In the flexible clamping components, the fixed plate 8 moves with the piston rod, and the elastic columns 9 evenly arranged circumferentially on its inner side move accordingly. The flexible pads 10 at the ends of the elastic columns 9 contact the main control board and gradually clamp it. During this process, the pressure sensor 11 embedded between the fixed plate 8 and the flexible pads 10 monitors the clamping pressure in real time to ensure that the clamping force is appropriate and to avoid damage to the main control board, thereby achieving a stable installation and precise fixation of the main control board.

[0041] In a further preferred embodiment of this utility model, such as Figure 2 As shown, the top surface of the adjusting plate is provided with an assembly groove 12, and a lead screw 13 is provided in the assembly groove 12. The two ends of the lead screw 13 are rotatably connected to the end side of the groove through thrust bearings 14. An adjusting block 15 is threaded on the lead screw 13. The bottom of the adjusting block 15 is slidably engaged with the bottom surface of the groove through a linear bearing, and the top is fixedly connected with an assembly seat 16 with a U-shaped cross section.

[0042] In this embodiment, when the position of the mounting base 16 needs to be adjusted, the drive screw 13 rotates around its own axis. Since both ends of the screw 13 are rotatably connected to the end side of the mounting groove 12 through the thrust bearing 14, the screw 13 can rotate stably. At this time, the adjusting block 15, which is threadedly engaged with the screw 13, tends to move along the axis of the screw 13 under the action of the thread. At the same time, the bottom of the adjusting block 15 slides with the bottom surface of the groove through the linear bearing. The linear bearing guides and limits the adjusting block 15, so that the adjusting block 15 can only move linearly along the axis of the screw 13. This drives the U-shaped mounting base 16, which is fixed on its top, to move together, so as to realize the position adjustment of the mounting base 16 in the length direction of the mounting groove 12 on the top surface of the adjusting plate to meet different assembly requirements.

[0043] In a further preferred embodiment of this utility model, such as Figure 2 As shown, an electric telescopic rod 18 is installed inside the assembly base 16 via a fixed shaft 17, and the output end of the electric telescopic rod 18 is connected to the bottom side of the assembly table 5 via a universal ball hinge.

[0044] In this embodiment, when the posture of the assembly table 5 needs to be adjusted, the output end of the electric telescopic rod 18 in the assembly base 16 begins to extend and retract. Since the output end is connected to the bottom side of the assembly table 5 through a universal ball hinge, the universal ball hinge has multi-directional rotation capability and can flexibly adapt to changes in the movement direction of the output end of the electric telescopic rod 18. When the output end of the electric telescopic rod 18 extends and retracts, it will drive the assembly table 5 to produce corresponding movements around the center point of the universal ball hinge. This can change the height of the assembly table 5 to a certain extent, and can also tilt the assembly table 5 by coordinating different degrees and directions of extension and retraction, thereby flexibly adjusting the angle and position of the assembly table 5 to meet the installation requirements of components such as the main control board in diverse assembly scenarios.

[0045] In a further preferred embodiment of this utility model, such as Figure 2 As shown, the end of the lead screw 13 is flexibly connected to the output shaft of the stepper motor 19 via a flexible coupling.

[0046] In this embodiment, the end of the lead screw 13 is connected to the output shaft of the stepper motor 19 through an elastic coupling. The elastic element inside the elastic coupling undergoes elastic deformation under the action of torque, which transmits the rotational power of the motor output shaft to the lead screw 13 steplessly, continuously and smoothly, causing the lead screw 13 to rotate synchronously around its own axis.

[0047] In a further preferred embodiment of this utility model, such as Figure 6 As shown, a servo motor 20 is provided on the top side of the fixed base 1, and the output end of the servo motor 20 is fixedly connected to the end of the adjustment table 3 through a flexible coupling.

[0048] In this embodiment, when the servo motor 20 starts, the rotational power of the motor output shaft is transmitted to the adjustment table 3 via the flexible coupling, ensuring that the adjustment table 3 can rotate synchronously with the motor output shaft, thereby achieving efficient and stable power transmission from the servo motor 20 to the adjustment table 3.

[0049] In a further preferred embodiment of this utility model, such as Figure 1-3 As shown, the surface of the flexible pad 10 is provided with anti-slip texture, and the anti-slip texture is adapted to the edge shape of the main control board.

[0050] In this embodiment, when the clamping device applies pressure to the main control board, the anti-slip texture penetrates into the tiny gaps or uneven areas on the edge of the main control board, effectively preventing the main control board from sliding in the horizontal direction. The flexible pad 10 itself is elastic and can deform according to the shape of the edge of the main control board, so that the anti-slip texture fits tightly with the edge of the main control board. This tight fit further increases the contact area and frictional resistance between the two. Even if the main control board is subjected to a large lateral force or torsional force, it can be firmly fixed in place, improving the reliability and stability of clamping.

[0051] In a further preferred embodiment of this utility model, such as Figure 5 As shown, the assembly table 5 is provided with a sliding guide groove assembly, which includes straight guide grooves 21 orthogonally distributed along the X / Y axes of the assembly table 5. Each straight guide groove 21 is provided with a slider 22, and the slider 22 is connected to the corresponding fixed plate 8.

[0052] In this embodiment, the slider 22 in each linear guide groove 21 can slide along the guide groove, and the slider 22 is connected to the corresponding fixed plate 8. By sliding the slider 22 in the guide groove, the fixed plate 8 can be moved flexibly and positioned precisely in the X and Y axis directions to meet the assembly position adjustment requirements of different parts in the assembly operation.

[0053] In a further preferred embodiment of this utility model, such as Figure 1 As shown, the outer edge of the side of the assembly table 5 is provided with an annular baffle 23 that is higher than its horizontal height.

[0054] In this embodiment, the annular baffle 23, with its structure that extends above the plane of the assembly table 5, plays a role in boundary protection and constraint during the assembly process. On the one hand, it can effectively prevent parts, tools, or products to be assembled placed on the assembly table 5 from accidentally sliding off the table due to external forces, thus avoiding material damage, loss, and potential safety accidents. On the other hand, it can clearly define the effective area of ​​the assembly operation, assisting operators in placing items in a standardized manner and planning the assembly process, so that materials and processes are in a relatively orderly space, thereby improving the efficiency and accuracy of the assembly operation and ensuring the safe, stable, and orderly progress of the entire assembly process.

[0055] Working principle: In the main control board assembly operation, the main control board is first placed on the assembly table 5. The annular baffle 23 on the outer edge of the side of the assembly table 5, which is higher than its horizontal height, plays a boundary protection and constraint role during the assembly operation due to its structure that is higher than the plane of the assembly table 5. On the one hand, it can effectively prevent the parts, tools or products to be assembled placed on the assembly table 5 from accidentally sliding off the table surface due to external force, avoiding material damage, loss and possible safety accidents; on the other hand, it can clearly define the effective area of ​​assembly operation, assist operators in placing items in a standardized manner and planning the assembly process, so that materials and processes are in a relatively orderly space, laying the foundation for the efficient and accurate development of subsequent assembly operations.

[0056] Subsequently, the servo motor 20 is started, and the rotational power of the output shaft of the servo motor 20 is transmitted to the adjustment table 3 through the flexible coupling. The elastic element inside the flexible coupling undergoes elastic deformation under the action of torque, ensuring that the adjustment table 3 can rotate synchronously with the motor output shaft, realizing efficient and stable power transmission from the servo motor 20 to the adjustment table 3. The bottom of the adjustment table 3 is connected to the relevant structure through the rotating shaft 2, allowing it to rotate around the vertical axis. By rotating the adjustment table 3 to a suitable angle, it prepares for the subsequent fine-tuning of the angle of the assembly table 5.

[0057] Next, the piston rods of the electric push rods 7 inside each side plate 6 of the assembly table 5 extend out, and the sliders 22 in each linear guide groove 21 slide along the guide groove under the drive of the piston rod. Since the sliders 22 are connected to the corresponding fixed plates 8, the sliding of the sliders 22 in the guide groove can drive the fixed plates 8 to move flexibly and be precisely positioned in the X and Y axis directions, thereby driving the flexible clamping components at their ends to move towards the main control board.

[0058] As the fixed plate 8 moves with the piston rod, the elastic columns 9 evenly distributed circumferentially on its inner side move accordingly. The flexible pads 10 at the ends of the elastic columns 9 contact the main control board and gradually clamp it. During this process, the pressure sensor 11 embedded between the fixed plate 8 and the flexible pads 10 monitors the clamping pressure in real time to ensure that the clamping force is appropriate and to avoid damage to the main control board. At the same time, the anti-slip texture on the surface of the flexible pads 10 penetrates into the tiny gaps or uneven areas on the edge of the main control board, effectively preventing the main control board from sliding in the horizontal direction. The flexible pads 10 themselves are elastic and can deform according to the shape of the edge of the main control board, so that the anti-slip texture fits tightly with the edge of the main control board, further increasing the contact area and frictional resistance between the two. Even if the main control board is subjected to a large lateral force or torsional force, it can be firmly fixed in place, realizing the stable installation and precise fixation of the main control board.

[0059] When the tilt of the assembly table 5 needs to be adjusted, the stepper motor 19 starts, and the end of the lead screw 13 is connected to the output shaft of the stepper motor 19 through an elastic coupling. The elastic coupling transmits the rotational power of the motor output shaft to the lead screw 13 steplessly, continuously and smoothly, causing the lead screw 13 to rotate synchronously around its own axis. Since the two ends of the lead screw 13 are rotatably connected to the end side of the assembly groove 12 through the thrust bearing 14, the stable rotation of the lead screw 13 is ensured. At this time, the adjusting block 15, which is threaded with the lead screw 13, tends to move along the axis of the lead screw 13 under the action of the thread. At the same time, the bottom of the adjusting block 15 slides with the bottom surface of the groove through the linear bearing. The linear bearing guides and limits the adjusting block 15, so that the adjusting block 15 can only move linearly along the axis of the lead screw 13, thereby driving the U-shaped assembly seat 16 fixed on its top to move together, realizing the position adjustment of the assembly seat 16 in the length direction of the assembly groove 12 on the top surface of the adjusting plate.

[0060] The output end of the electric telescopic rod 18 inside the assembly base 16 begins to extend and retract. Since the output end is connected to the bottom side of the assembly table 5 through a universal ball hinge, the universal ball hinge has multi-directional rotation capability and can flexibly adapt to changes in the movement direction of the output end of the electric telescopic rod 18. When the output end of the electric telescopic rod 18 extends and retracts, it will drive the assembly table 5 to produce corresponding movements around the center point of the universal ball hinge. This can not only change the height of the assembly table 5 to a certain extent, but also tilt the assembly table 5 by coordinating different degrees and directions of extension and retraction, thereby flexibly adjusting the angle and position of the assembly table 5 to meet diverse assembly needs.
