Abstract
Description
Technical Field
[0001] This utility model belongs to the field of optical devices, specifically relating to a manual crimping mechanism, crimping assembly, and testing device. Background Technology
[0002] After production, optical devices require comprehensive performance testing. The test data serves as the parameter basis for the devices' shipment and is provided to customers for reference. When performance testing is required, the flexible circuit board in the optical device needs to be temporarily connected to the PCB board used for testing to enable the testing.
[0003] When a temporary connection between a flexible circuit board and a PCB is required, the conventional method is to use a crimping device to press the flexible circuit board onto the PCB, thereby achieving a crimped connection. However, in existing technologies, the crimping device is often held by the operator during crimping, which means the crimping device cannot provide a stable crimping force for an extended period, leading to an unstable crimped connection between the flexible circuit board and the PCB. Utility Model Content
[0004] This utility model provides a manual crimping mechanism, crimping component and testing device, the purpose of which is to solve the problem that the crimping component in the prior art cannot provide a stable crimping force for a long time.
[0005] To achieve the above objectives, this utility model provides a manual crimping mechanism, characterized in that:
[0006] A crimping member, the crimping member being provided with a crimping portion; and
[0007] The crimping structure includes a mounting base, an operating handle, and an arc-shaped connecting plate. The upper end of the operating handle is rotatably mounted on the mounting base. The lower part of the mounting base has a guide opening. The crimping member is accommodated in the guide opening and can extend and retract vertically within the guide opening. The two ends of the arc-shaped connecting plate are rotatably connected to the operating handle and the crimping member, respectively.
[0008] When a stable crimping of a flexible circuit board and a PCB board is required, the operator manually rotates the operating handle, causing the crimping component to move downwards. The crimping part of the crimping component achieves a stable crimping of the flexible circuit board and the PCB board. Simultaneously, because the operating handle presses against the arc-shaped connecting plate, which further restricts the crimping component, it cannot automatically spring back. This allows the crimping component to provide a stable crimping force, overcoming the shortcomings of existing technologies.
[0009] Preferably, to address the issue of hard contact between the crimping component and the flexible circuit board, the crimping component in this solution includes a crimping section and a connecting section. The connecting section and the crimping section are telescopically connected, and the connecting section is connected to the crimping structure. A spring is disposed between the connecting section and the crimping section, with both ends of the spring engaging with the connecting section and the crimping section respectively. This solution, by making the connecting section and the crimping section telescopically connected and by using a spring for buffering, solves the problem of damage to the flexible circuit board caused by hard contact between the crimping component and the flexible circuit board.
[0010] Preferably, in order to adjust the pressing force of the pressing part on the flexible circuit board, the pressing component of this solution further includes a screw and a threaded hole. The screw and the threaded hole are respectively disposed in the pressing section and the connecting section. The pressing section and the connecting section are threadedly connected by the screw and the threaded hole, and the spring is sleeved on the screw.
[0011] This solution allows for adjustment of the distance between the connecting section and the crimping section by rotating the bolt and threaded hole. When the distance between the connecting and crimping sections is adjusted, the deformable range of the spring located between them differs, thus adjusting the crimping force of the crimping part on the flexible circuit board. This solution allows for adjustment of different crimping forces according to different application scenarios, making it more practical.
[0012] Preferably, since the surface of the flexible circuit board is planar, the pressing part is designed to adhere to the surface of the flexible circuit board. In this solution, the pressing part is a pressing block, and the pressing surface of the pressing block is planar. By setting the pressing surface of the pressing block to a planar surface, when the pressing surface contacts the flexible circuit board, the pressing surface adheres more closely to the surface of the flexible circuit board, resulting in a more stable pressing of the flexible circuit board.
[0013] Preferably, to address the issue of the crimping portion tilting along with the crimping member when it is tilted, the crimping portion in this design is rotatably mounted on the end of the crimping member. Because the crimping portion is rotatably mounted, when the crimping member is tilted, the crimping portion can automatically adjust to a horizontal position due to gravity, thereby ensuring a better fit between the crimping portion and the surface of the flexible circuit board.
[0014] The second aspect of this utility model discloses a crimping assembly, including the aforementioned manual crimping mechanism and a moving mechanism, wherein the moving mechanism is connected to the manual crimping mechanism. In this design, the manual crimping mechanism drives the crimping assembly to move, and after the manual crimping mechanism moves, its crimping position changes. Therefore, when different flexible circuit boards need to be crimped, the crimping position of the manual crimping mechanism can be adjusted accordingly, making it more practical.
[0015] Preferably, in order to achieve the X-axis position of the pressing mechanism, the moving mechanism of this solution includes an X-axis moving unit, which is used to drive the pressing mechanism to move along the X-axis direction.
[0016] To achieve the Y-axis position of the crimping mechanism, the moving mechanism described in this solution includes a Y-axis moving unit, which is used to drive the crimping mechanism to move along the Y-axis direction.
[0017] In order to achieve the Z-axis position of the crimping mechanism, the moving mechanism described in this solution includes a Z-axis moving unit, which is used to drive the crimping mechanism to move along the Z-axis direction.
[0018] The third aspect of this utility model discloses a testing device, including the aforementioned crimping assembly. This solution solves the problem that the crimping component cannot provide a stable crimping force to the flexible circuit board by using the aforementioned crimping assembly to crimp the flexible circuit board and the PCB board.
[0019] The beneficial effects of this invention are as follows: When a flexible circuit board and a PCB board need to be stably crimped, the operator manually rotates the operating handle, causing the crimping component to move downwards. The crimping part of the crimping component achieves a stable crimping of the flexible circuit board and the PCB board. Simultaneously, because the operating handle presses against the arc-shaped connecting plate, the arc-shaped connecting plate further restricts the crimping component, preventing it from automatically springing back. This allows the crimping component to provide a stable crimping force, overcoming the shortcomings of existing technologies. Attached Figure Description

Detailed Implementation
[0026] 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.
[0027] 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.
[0028] Example 1
[0029] The basics are as follows: Figure 1 As shown, a crimping mechanism includes a crimping member 1 and a crimping structure 3.
[0030] In this embodiment, the crimping member 1 is used for crimping flexible circuit boards and PCB boards. The crimping member 1 is a crimping rod. A crimping part 2 is provided at the lower end of the crimping member 1. The crimping part 2 is block-shaped and can be made of Teflon material. The bottom of the crimping part 2 is a crimping surface, which is flat and can fit more closely to the flexible circuit board. The crimping part 2 is preferably rotatably mounted on the lower end of the crimping section 11 using a rotating shaft. In practice, a notch is provided at the lower end of the crimping section 11. The notch is a rectangular notch, and a rotating shaft is provided inside the notch. A connecting hole is provided at the top of the crimping part 2, and the connecting hole is fitted onto the rotating shaft, so that the crimping part 2 can rotate around the rotating shaft.
[0031] Taking one application scenario as an example: when the crimping component 1 shifts during the crimping process (i.e., the crimping component 1 is not in a vertical state), the crimping part 2 located at the lower end of the crimping component 1 adjusts to a horizontal state under the action of gravity. The crimping surface of the crimping part 2 is in a horizontal state, and the horizontal crimping surface is in contact with the surface of the flexible circuit board, thereby making the flexible circuit board and the PCB board stably crimped.
[0032] In this embodiment, the crimping structure 3 is fixedly connected to the crimping member 1, and the crimping structure 3 is used to drive the crimping member 1 to move up and down. At the same time, when the crimping member 1 reaches the crimping position, the crimping structure 3 will lock to prevent the crimping member 1 from springing back upward.
[0033] like Figure 2As shown, the crimping structure 3 in this embodiment includes a mounting base 31, an operating handle 32, and an arc-shaped connecting plate 33. The upper part of the mounting base 31 is provided with a rotating shaft mounting portion, on which the rotating shaft is mounted. The lower part of the mounting base 31 is provided with a guide opening, which accommodates the upper end of the crimping member 1. The crimping member 1 can move up and down within the guide opening. The upper end of the operating handle 32 is rotatably connected to the rotating shaft, and the operating handle 32 can rotate around the rotating shaft. The arc-shaped connecting plate 33 is generally arc-shaped, with its upper end rotatably connected to the top of the crimping member 1 via a rotating shaft, and its other end rotatably connected to the operating handle 32.
[0034] Taking one application scenario as an example: When it is necessary to crimp a flexible circuit board and a PCB board, the operator rotates the operating handle 32 downwards. During the rotation of the operating handle 32, the arc-shaped connecting plate 33 moves downwards accordingly. Since the arc-shaped connecting plate 33 is connected to the crimping member 1, the arc-shaped connecting plate 33 can push the crimping member 1 downwards, and the crimping member 1 drives the configured crimping part 2 to crimp the flexible circuit board. At the same time, when the operating handle 32 is rotated downwards to its maximum angle, the arc-shaped connecting plate 33 abuts against the crimping member 1, preventing the crimping member 1 from springing back upwards on its own, ensuring that the crimping part 2 can continuously and stably provide crimping force to the flexible connecting plate.
[0035] The following detailed description illustrates the specific implementation method: When it is necessary to press the flexible circuit board and the PCB board together, the user manually operates the operating handle 32 to move the pressing member 1 downwards. The pressing part 2 configured on the pressing member 1 can press the flexible circuit board and the PCB board together. At the same time, since the pressing member 1 cannot spring back upwards on its own, the pressing member 1 can provide a stable pressing force on the flexible circuit board and the PCB board.
[0036] Example 2
[0037] The difference between this embodiment and Embodiment 1 is that, as Figure 3 As shown, the crimping component 1 in this embodiment includes a crimping section 11 and a connecting section 12, both of which are rod-shaped. A crimping portion 2 is provided at the lower end of the crimping section 11.
[0038] In this embodiment, the lower end of the connecting section 12 is provided with a threaded hole, and a bolt is installed inside the threaded hole. The bolt is installed in the threaded hole through threads, and can extend or retract within the threaded hole. The upper end of the bolt is threadedly connected to the threaded hole, and the lower end of the bolt is telescopically connected to the crimping member 1. In a specific implementation, a receiving channel is provided at the top of the crimping section 11, and the end of the bolt is received inside the receiving channel, allowing the bolt to extend and retract within the receiving channel. A limiting ring is provided at the opening of the receiving channel to prevent the bolt from separating from the crimping section 11. At the same time, the cross-section of the receiving channel is hexagonal, so that the bolt and the receiving channel can mutually limit each other, preventing the screw 14 from rotating on its own inside the receiving channel.
[0039] Taking one application scenario as an example: when it is necessary to adjust the crimping depth of the crimping part 1, the distance between the crimping section 11 and the connecting section 12 can be adjusted by using bolts, thereby adjusting the crimping depth of the crimping part 1, so that the crimping part 2 can accurately crimp the flexible circuit board and the PCB board.
[0040] In this embodiment, a spring 13 is disposed between the connecting section 12 and the crimping section 11. The spring 13 is sleeved on the surface of the bolt, and its two ends abut against the lower end of the connecting section 12 and the upper end of the crimping section 11, respectively. The spring 13 reduces the crimping force of the crimping part 2 on the flexible circuit board and the PCB board, thus preventing damage to the flexible circuit board and the PCB board due to hard contact.
[0041] Example 3
[0042] The difference between this embodiment and Embodiment 2 is that, as Figure 4 As shown, in this embodiment, a threaded hole is located at the top of the crimping section 11, and the lower end of the bolt is also accommodated inside the threaded hole. The upper end of the bolt is telescopically connected to the connecting section 12. In specific implementation, a receiving channel is provided at the top of the connecting section 12, and the end of the bolt is accommodated inside the receiving channel, allowing the bolt to telescopically move within the receiving channel. A limit ring is provided at the opening of the receiving channel to restrict the bolt from separating from the connecting section 12. At the same time, the cross-section of the receiving channel is hexagonal, allowing the bolt to be mutually restrained by the receiving channel, preventing the screw 14 from rotating on its own inside the receiving channel.
[0043] Example 4
[0044] This embodiment provides a crimping assembly, such as... Figure 5 As shown, it includes a manual pressing mechanism and a moving mechanism 4, as described in Embodiment 1, Embodiment 2, or Embodiment 3. The manual pressing mechanism and the moving mechanism 4 are fixedly connected. The moving mechanism 4 is used to drive the manual pressing mechanism to move, thereby changing the pressing position.
[0045] The moving mechanism 4 in this embodiment includes an X-axis moving unit, a Y-axis moving unit, and a Z-axis moving unit. The X-axis moving unit includes a crossbeam 41 and a transverse block. The crossbeam 41 has an X-axis direction guide groove, and the transverse block has a mounting base 31 for the pressing structure 3 fixedly mounted on it. A threaded hole is provided on the back of the transverse block. The transverse block can move along the X-axis direction guide groove, thereby causing the pressing structure 3 to move in the X-axis direction. Simultaneously, when it is necessary to lock the transverse block, a screw or bolt is screwed into the threaded hole to fix the transverse block to the crossbeam 41.
[0046] The Z-axis moving unit in this embodiment includes two columns 42 and a lifting block. The two columns 42 are symmetrically arranged. Each column 42 has a threaded hole, and the lifting block has Z-axis guide grooves on both sides. The lifting block and the crossbeam 41 can be integrally formed, or they can be separate components, fixedly connected by welding or fasteners. When Z-axis movement is required, the lifting block moves up and down, thereby driving the crossbeam 41 to move up and down. Simultaneously, when locking the lifting block, a screw or bolt is screwed into the threaded hole to fix the lifting block to the column 42.
[0047] The Y-axis moving unit of this embodiment includes a base 43 and a telescopic block. The base 43 is rectangular and located at the bottom. Threaded holes are provided on both sides of the base 43, and Y-axis guide grooves are constructed on the telescopic blocks on both sides. The telescopic block and the column 42 can be integrally formed, or they can be separate components, fixedly connected by welding or fasteners. When Y-axis movement is required, the telescopic block extends and retracts, thereby driving the column 42 to extend and retract as well. Simultaneously, when locking the telescopic block, screws or bolts are screwed into the threaded holes to fix the telescopic block to the base 43.
[0048] Taking one application scenario as an example: when different PCB boards and flexible circuit boards are pressed together, the X-axis moving unit, Y-axis moving unit and Z-axis moving unit work together to move the pressing mechanism precisely above the position to be pressed, thus ensuring the precise pressing of the flexible circuit board and the PCB board.
[0049] It should be noted that in this embodiment, the moving mechanism 4 includes an X-axis moving unit, a Y-axis moving unit, and a Z-axis moving unit. However, in some other embodiments, the moving mechanism 4 may only include any two of the X-axis, Y-axis, and Z-axis moving units. Of course, in this case, the flexibility of the moving mechanism 4 will be reduced. Furthermore, this embodiment provides a structure for the moving mechanism 4; however, in some other embodiments, the moving mechanism 4 can be other types of moving mechanisms. For example, the moving mechanism 4 can also be configured as a six-axis robotic arm or similar device to achieve the movement of the manual pressing mechanism.
[0050] Example 5
[0051] This embodiment provides a testing device, including the crimping assembly of Embodiment 4. The crimping assembly crimps and connects the PCB board to the flexible circuit board of the optical device.
[0052] To secure the PCB board and the flexible circuit board of the optical device, the PCB board and the flexible circuit board of the optical device can be fixed on their respective worktables.
[0053] 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. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
