[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0024] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.

[0025] refer to Figures 1 to 8 This application discloses a mounting mechanism for mounting flexible circuit boards (FPCs) to components. The components can be the housing of a product, or a part of the product used to mount the FPC. Besides these, the mounting mechanism can also be applied to other scenarios, which are not specifically limited here. The disclosed mounting mechanism includes a fixture 30, a clamping assembly 10, and a mounting assembly 20.

[0026] The fixture 30 is a load-bearing component that provides a support base for the flexible circuit board and components. Optionally, before mounting, the flexible circuit board can be placed in the fixture 30 and moved synchronously by transferring the fixture 30, so as to facilitate the transfer of the fixture 30 and the flexible circuit board to the mounting station.

[0027] Then, the parts can be transferred to the fixture 30 by a robot arm, so that the parts can be carried by the fixture 30 and positioned to correspond with the flexible circuit board, so as to lay the foundation for subsequent mounting operations.

[0028] The clamping assembly 10 is used to clamp the parts so that the parts can be fixed on the fixture 30. In this way, when the parts are subjected to force during the placement process, they will not move relative to the fixture 30 or even fall off the fixture 30, thus ensuring the stability of the parts during the placement process.

[0029] The mounting assembly 20 is used to apply mounting force to the flexible circuit board. The mounting assembly 20 may include a movable support top 21 for supporting the flexible circuit board so that the flexible circuit board is mounted to the component.

[0030] Based on the above settings, the mounting mechanism in this embodiment can press and limit the parts through the clamping component 10 during the mounting process to prevent the parts from moving randomly, and apply a supporting force to the flexible circuit board through the mounting component 20 to mount the flexible circuit board to the parts.

[0031] Compared to the manual mounting method in related technologies, the embodiments of this application can improve the mounting efficiency of flexible circuit boards and effectively avoid the situation where the mounting position is offset due to human factors, resulting in low mounting accuracy. This can improve mounting accuracy, ensure product quality, and also improve mounting efficiency and reduce the labor intensity of personnel.

[0032] refer to Figure 6In some embodiments, the mounting assembly 20 may include a first driving member 22 and a pressure sensing element 23. The pressure sensing element 23 is disposed between the support top 21 and the driving end of the first driving member 22, and is used to detect the driving force of the first driving member 22 on the support top 21. Based on this, during the driving process of the first driving member 22, the pressure sensing element 23 can carry the support top 21 towards the flexible circuit board, so that the support top 21 provides support for the flexible circuit board, enabling the flexible circuit board to move towards the component and ultimately be mounted to the component.

[0033] In addition, during the mounting process, the pressure detection element 23 can detect the pressure of the support top 21 on the pressure detection element 23 in real time. According to the principle of action and reaction force, the supporting force of the support top 21 on the flexible circuit board can be obtained, which can lay the data foundation for subsequent control of the magnitude of the supporting force of the support top 21 on the flexible circuit board.

[0034] Optionally, the pressure detection element 23 can be a pressure sensor, or other components, which are not specifically limited here; the first driving component 22 can be an electric cylinder, a pneumatic cylinder, a hydraulic cylinder, etc., and its specific form is not limited.

[0035] Continue to refer to Figure 6 In some embodiments, the mounting assembly 20 may further include a movable base 24, which is disposed on the pressure sensing element 23, and the support top 21 may be disposed on the movable base 24 so as to fix the support top 21 in place by the movable base 24.

[0036] The support top 21 may include a top rod 211, which is disposed on the movable seat 24. Thus, under the driving action of the first driving member 22, the movable seat 24 can drive the top rod 211 to move, thereby realizing the support function for the flexible circuit board.

[0037] Optionally, the support top 21 may include one support rod 211 or multiple support rods 211, and the multiple support rods 211 are distributed at different positions of the movable seat 24, so as to support different positions of the flexible circuit board, thereby increasing the support area of ​​the flexible circuit board and alleviating the problem of bending deformation and breakage of the flexible circuit board caused by the concentration of support force on the flexible circuit board.

[0038] Furthermore, the support top 21 may also include an extension top block 212, which is disposed on the movable seat 24 and spaced apart from the top rod 211 in a plane perpendicular to the moving direction of the support top 21. Based on this, during the process of the first driving member 22 driving the movable seat 24 to move, the movable seat 24 can also drive the extension top block 212 to move synchronously, so that the flexible circuit board can be supported by the extension top block 212 in conjunction with the top rod 211, thereby further increasing the support area.

[0039] refer to Figure 8 In some embodiments, the fixture 30 may be provided with a clearance hole 32, through which the support top 21 passes and supports the flexible circuit board carried on the fixture 30. Based on this, by providing the clearance hole 32, clearance space can be provided for the support top 21 to prevent obstruction of the movement of the support top 21 and ensure that the support top 21 can smoothly support the flexible circuit board.

[0040] Optionally, the clearance hole 32 may include a push rod hole and a push block hole, wherein the push rod hole is for passing through the push rod 211 and the push block hole is for passing through the push block.

[0041] refer to Figures 1 to 3 In some embodiments, the support top 21 of the mounting assembly 20 may be located on one side of the fixture 30 to support the flexible circuit board from one side of the fixture 30; the clamping part of the clamping assembly 10 may be located on the opposite side of the fixture 30 from the support top 21 to clamp the part from the other side of the fixture 30. Therefore, when the support top 21 supports the flexible circuit board from one side, the part can be clamped and fixed by the clamping part to ensure the stability of the part during the mounting process.

[0042] Optionally, the mounting mechanism may also include a mounting bracket connected to one side of the fixture 30, and the mounting assembly 20 connected to the mounting bracket, so as to support and fix the mounting assembly 20 through the mounting bracket, thereby ensuring the stability of the mounting assembly 20.

[0043] Continue to refer to Figure 8 In some embodiments, the fixture 30 may be provided with a positioning post 31, which is used to engage with the positioning hole provided on the flexible circuit board. Based on this, when the flexible circuit board is placed in the fixture 30, the positioning post 31 can be inserted into the positioning hole, thereby realizing the positioning of the flexible circuit board. On the one hand, it improves the limitation of the flexible circuit board, and on the other hand, it can accurately position the flexible circuit board to ensure the positional accuracy of the flexible circuit board.

[0044] refer to Figure 7 In some embodiments, the clamping assembly 10 may include a second drive member 11 and a clamping head 12. The drive end of the second drive member 11 is connected to the clamping head 12 and is used to drive the clamping head 12 to clamp the part, thereby ensuring the stability of the part during the mounting process.

[0045] Optionally, the second driving component 11 can be a pneumatic cylinder, a hydraulic cylinder, an electric cylinder, etc. Of course, it can also be other forms, which are not specifically limited here.

[0046] Considering that after the fixture 30 carries the flexible circuit board to the mounting station, the parts need to be transferred to the fixture 30, in order to avoid the clamping assembly 10 interfering with the transfer of the parts, the clamping assembly 10 in this embodiment may also include a cantilever 13. One end of the cantilever 13 is connected to the second drive member 11, and the cantilever 13 is rotatable around the axis of the second drive member 11. The pressure head 12 is located at the other end of the cantilever 13.

[0047] Based on the above settings, when it is necessary to transfer a part to the fixture 30, the pressure head 12 is rotated away from the fixture 30 by the cantilever 13 to prevent the pressure head 12 or the cantilever 13 from contacting the part; when the part is transferred onto the fixture 30, the pressure head 12 can be rotated to the position corresponding to the part by the cantilever 13 so as to press the part by the pressure head 12 and ensure the stability of the part on the fixture 30.

[0048] Optionally, the second driving member 11 may include a main body and a driving shaft as the driving end, which can both extend and rotate relative to the main body; one end of the cantilever 13 is connected to the driving shaft so as to drive the cantilever 13 to extend, rotate and rotate via the driving shaft.

[0049] For example, the power for the rotation of the drive shaft relative to the main body can come from manual operation or electric motor drive.

[0050] In some embodiments, the mounting mechanism may further include a control element electrically connected to the first drive member 22 and the pressure detection element 23, respectively. Thus, during the mounting process, the pressure detection element 23 can detect the mounting pressure in real time and transmit the mounting pressure information to the control element. After analysis and processing by the control element, it can send control commands to the first drive member 22 to control the mounting pressure. Even when the support top 21 moves rapidly, a soft landing and overshoot-free mounting process can be achieved, maximizing the protection of the flexible circuit board.

[0051] Therefore, the bonding mechanism in this embodiment can achieve precise bonding of the flexible circuit board by controlling the bonding pressure, so as to prevent the flexible circuit board from being damaged due to excessive pressure or the flexible circuit board from being unable to be bonded properly due to insufficient pressure.

[0052] In this embodiment of the application, the mounting process of the flexible circuit board is as follows:

[0053] After removing the release paper, the flexible circuit board with the coaxial cable welded and the circuit board connected is assembled onto the fixture 30, ensuring that the positioning holes of the flexible circuit board are aligned with the positioning posts 31 of the fixture 30, and assembled in place.

[0054] Move fixture 30 to the mounting station, and use a robot to transfer the parts onto fixture 30 and set them up to correspond with the flexible circuit board.

[0055] When the clamping assembly 10 is activated, it clamps the parts through the clamping part;

[0056] When the mounting assembly 20 is activated, the flexible circuit board is supported by the support top 21, so that the flexible circuit board is brought close to and mounted to the part. During this process, the positioning hole of the flexible circuit board can be disengaged from the positioning post 31 of the fixture 30 and fitted onto the positioning pin of the part, thereby ensuring the positional accuracy of the flexible circuit board.

[0057] After the flexible circuit board is in place, the support top 21 moves back, the clamping part releases the clamping on the parts and returns to its original position, and the fixture 30 carries the assembled flexible circuit board and parts to the next station.

[0058] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
