[0042] Referring to Figures 1 to 3 , the circuit detection device for a flexible circuit board according to an embodiment of the present utility model, the circuit detection device for a flexible circuit board includes a frame (not shown in the figure), two groups of first clamping components 20, two groups of second clamping components 30, and a detection component 70. The frame is provided with a first sliding module 10, and the sliding direction of the first sliding module 10 extends along the first horizontal direction; the two groups of first clamping components 20 are respectively slidably arranged on the first sliding module 10 through mounting plates 21, the length direction of the mounting plate 21 extends along the second horizontal direction, the first horizontal direction is perpendicular to the second horizontal direction, the first clamping component 20 is slidably arranged on the mounting plate 21 along the second horizontal direction, the two groups of first clamping components 20 are arranged opposite to each other, and the first clamping component 20 is used for clamping two adjacent corners of the flexible circuit board; the second clamping component 30 is arranged on the mounting plate 21 and is respectively located on one side of the two groups of first clamping components 20, the two groups of second clamping components 30 are arranged opposite to each other, and the second clamping component 30 is used for clamping the other two adjacent corners of the flexible circuit board. The detection component 70 is movably arranged on the frame and is located on both the upper and lower sides of the first clamping component 20. The detection component 70 includes a third sliding module 71 and a detection jig 72. The detection jig 72 is arranged at the output end of the third sliding module 71 through a lifting component 73, the detection jig 72 is arranged at the output end of the lifting component 73, the third sliding module 71 drives the detection jig 72 to move on the flexible circuit board 1, and the lifting component 73 drives the detection jig 72 to be away from or in contact with the circuit on the flexible circuit board 1.

[0043] Specifically, the specific implementation manner is as follows: The circuit detection device for the flexible circuit board mainly includes a frame, a first sliding module 10, two groups of first clamping components 20, and two groups of second clamping components 30.

[0044] First, the frame is the basic structure of the fixture, which is used to support and fix the entire fixture. A first sliding module 10 is arranged on the frame. The sliding direction of the first sliding module 10 extends along the first horizontal direction (i.e., the left-right direction shown in the figure), that is, it can slide along this direction to facilitate the adjustment of the working position of the fixture. Secondly, two groups of first clamping components 20 are respectively slidably arranged on the first sliding module 10 through mounting plates 21. The length direction of the mounting plate 21 extends along the second horizontal direction (i.e., the front-back direction shown in the figure), and the first horizontal direction is perpendicular to the second horizontal direction. Such a design enables the first clamping components 20 to not only slide along the first horizontal direction on the first sliding module 10, but also slide along the second horizontal direction on the mounting plate 21, thereby realizing the fine adjustment of the clamping position of the flexible circuit board and improving the accuracy and flexibility of clamping. The two groups of first clamping components 20 are arranged oppositely to clamp two adjacent corners of the flexible circuit board. Finally, two groups of second clamping components 30 are arranged on the mounting plate 21 and are respectively located on one side of the two groups of first clamping components 20. Similarly, the two groups of second clamping components 30 are also arranged oppositely to clamp the other two adjacent corners of the flexible circuit board. Through such a layout, the four groups of clamping components act together on the four corners of the flexible circuit board, achieving a stable and reliable clamping effect.

[0045] When the first clamping component 20 and the second clamping component 30 clamp and fix the flexible circuit board 1 and tighten it, the detection component 70 can start the circuit detection of the flexible circuit board 1. Specifically, the third sliding module 71 includes sliding modules in the first direction and the second direction, which move successively or synchronously respectively, driving the detection jig 72 on its output end to move to the upper and lower sides of the flexible circuit board 1, specifically to the position of the circuit to be detected; then the lifting component 73 can drive the detection jig 72 to approach and contact the circuit on the flexible circuit board 1 respectively, so that the circuit of the flexible circuit board 1 can be detected by using the detection program.

[0046] It should be noted that the lifting component 73 can also be driven by a sliding module, or driven by a cylinder or a hydraulic cylinder. Moreover, an elastic member for buffering can be arranged on the lifting component 73 to prevent damage to the circuit board caused by impact when the detection jig 72 is attached to the flexible circuit board 1.

[0047] During specific use, first place the flexible circuit board within the working area of the fixture. Then, by adjusting the sliding positions on the first sliding module 10 and the mounting plate 21, align the two sets of first clamping components 20 and the two sets of second clamping components 30 with the four corners of the flexible circuit board respectively. Next, start the clamping mechanism of the fixture to simultaneously clamp the four corners of the flexible circuit board with the four sets of clamping components, thereby achieving stable clamping of it. After stable clamping, through the fine adjustment of the first clamping component 20 in the second horizontal direction and the fine adjustment of the mounting plate 21 in the first horizontal direction, the flexible circuit board can be pulled taut, which is convenient for the detection fixture to detect the flexible circuit board 1.

[0048] Therefore, it can be understood that the circuit detection device for the flexible circuit board according to the embodiment of the present invention has at least the following beneficial effects: after clamping the four corners of the flexible circuit board through the first clamping component 20 and the second clamping component 30 respectively, the first clamping component 20 that can slide through the first sliding module 10 slides in the first horizontal direction and the second horizontal direction respectively, thereby tightening the flexible circuit board, which is convenient for the detection fixture to detect the circuit structures on the upper and lower sides.

[0049] Refer to Figures 1 to 2 , in some embodiments of the present invention, a second sliding module 40 is provided on the mounting plate 21. The sliding direction of the second sliding module 40 extends along the second horizontal direction. The first clamping component 20 is provided at the output end of the second sliding module 40, and the second sliding module 40 drives the first clamping component 20 to slide in the second horizontal direction.

[0050] Specifically, the first clamping component 20 is provided at the output end of the second sliding module 40. When it is necessary to adjust the position of the first clamping component 20 in the second horizontal direction, just operate the second sliding module 40, which can drive the first clamping component 20 to slide along the second horizontal direction. This structure not only improves the flexibility of the fixture but also enables the fixture to adapt to flexible circuit boards of different sizes and shapes, thereby further improving the versatility and practicality of the fixture. In practical applications, the operator can precisely control the position of the first clamping component 20 by adjusting the second sliding module 40 according to the specific size and shape of the flexible circuit board. In this way, regardless of how the size and shape of the flexible circuit board change, the fixture can provide a stable and reliable clamping effect to ensure the smooth progress of the processing process.

[0051] Refer to Figures 1 to 3, in some embodiments of the present utility model, both the first clamping assembly 20 and the second clamping assembly 30 include: a mounting portion 51, two first connecting rods 52, two second connecting rods 54, and a jaw 53. The mounting portion 51 is disposed on the second sliding module 40, and a first driving member 55 is provided on the mounting portion 51; one ends of the two first connecting rods 52 are respectively connected to the output end of the first driving member 55 through gears, and the two first connecting rods 52 are oppositely disposed, and the first driving member 55 drives the first connecting rods 52 to swing around the rotation center of the gear; one ends of the two second connecting rods 54 are respectively hinged to the mounting portion 51 and are oppositely disposed; the other ends of the two first connecting rods 52 are respectively hinged to one end of the jaw 53, and the other ends of the two second connecting rods 54 are respectively hinged to the middle of the jaw 53, and the swinging first connecting rods 52 drive the jaw 53 to move to clamp or release the flexible printed circuit board.

[0052] Specifically, each clamping assembly includes a mounting portion 51, which is disposed on the second sliding module 40. A first driving member 55 is provided on the mounting portion 51 to provide the power required for the clamping action. Next, one ends of the two first connecting rods 52 are respectively connected to the output end of the first driving member 55 through gears. The two first connecting rods 52 are oppositely disposed, and when the first driving member 55 is started, it drives the first connecting rods 52 to swing around the rotation center of the gear. In addition, there are two second connecting rods 54, one ends of which are respectively hinged to the mounting portion 51 and are also oppositely disposed. The jaw 53 is the key part of the clamping assembly for actually clamping the flexible printed circuit board. The other ends of the two first connecting rods 52 are respectively hinged to one end of the jaw 53, while the other ends of the two second connecting rods 54 are respectively hinged to the middle of the jaw 53. When the first connecting rods 52 swing, they drive the jaw 53 to move, thereby realizing the function of clamping or releasing the flexible printed circuit board. Through the first connecting rods 52 and the second connecting rods 54, the two jaws 53 can be relatively opened so that the included angle of the jaws 53 reaches 180°, which is convenient for the printed circuit board to move into the clamping area without being interfered by the jaws 53, and finally it is convenient for the clamping assembly to clamp the flexible printed circuit board.

[0053] In practical applications, when it is necessary to clamp the flexible printed circuit board, the first driving member 55 is started and drives the first connecting rods 52 to swing around the rotation center of the gear. This swinging action further drives the jaw 53 to move to tightly clamp the flexible printed circuit board. On the contrary, when it is necessary to release the flexible printed circuit board, the first driving member 55 is driven in the reverse direction to release the jaw 53 and release the flexible printed circuit board.

[0054] Furthermore, in some embodiments of the present utility model, a protective pad (not shown in the figure) is provided on the surface of the jaw 53 in contact with the flexible printed circuit board. Further still, in some embodiments of the present utility model, the protective pad is a rubber pad.

[0055] Specifically, the protective pad is ingeniously installed at the key part where the clamping jaw 53 contacts the flexible printed circuit board. When the clamping jaw 53 clamps the flexible printed circuit board, the protective pad can effectively disperse the clamping force, avoid causing excessive local pressure on the flexible printed circuit board, and thus prevent it from being damaged. Further, a rubber pad is specifically selected as the material of the protective pad. The rubber pad has good elasticity and wear resistance, can effectively adapt to the shape of the flexible printed circuit board, and provide stable support and protection during the clamping process. At the same time, the softness of the rubber pad can also absorb the impact during clamping to a certain extent, further protecting the flexible printed circuit board from damage. In practical applications, the operator only needs to place the flexible printed circuit board at the designated position of the fixture and then start the clamping component. With the assistance of the protective pad, the clamping jaw 53 can stably clamp the flexible printed circuit board without causing any damage to it. When it is necessary to release the flexible printed circuit board, only the clamping component needs to be operated in reverse.

[0056] Referring to Figures 1 to 2 , in some embodiments of the present utility model, the first sliding module 10 includes a second driving member 11, a first lead screw 12 and a first slider 13. The lead screw includes two threads with opposite thread directions. One end of the second driving member 11 is connected to the output end of the second driving member 11, and the first sliders 13 are respectively screwed on the two threads with opposite thread directions. One end of the mounting plate 21 is arranged on the first slider 13.

[0057] The first sliding module 10 mainly includes a second driving member 11, a first lead screw 12 and a first slider 13. Among them, the first lead screw 12 includes two threads with opposite thread directions. This design enables that when the second driving member 11 is started, it can simultaneously drive the two first sliders 13 to move relatively or in opposite directions on the first lead screw 12.

[0058] Specifically, one end of the second driving member 11 is connected to its output end to provide power for the first sliding module 10. The two first sliders 13 are respectively screwed on the threads of the two sections of threads with opposite rotation directions. When the second driving member 11 is started, it will drive the two first sliders 13 to move at the same time through the rotation of the first lead screw 12. Since the rotation directions of the threads are opposite, the two first sliders 13 will move relative to or towards each other along the first lead screw 12. Further, one end of the mounting plate 21 is arranged on the first slider 13. In this way, when the first slider 13 moves, the mounting plate 21 will also move therewith. Since the second sliding module 40 and the clamping assembly are arranged on the mounting plate 21, this design enables the clamping assembly to be accurately slidably adjusted in the first horizontal direction to adapt to flexible circuit boards of different sizes and shapes. In practical applications, the operator can drive the first sliding module 10 to work by controlling the second driving member 11. When the position of the clamping assembly in the first horizontal direction needs to be adjusted, the second driving member 11 only needs to be started to drive the two first sliders 13 to move relative to or toward each other through the rotation of the first lead screw 12, thereby driving the mounting plate 21 and the clamping assembly to perform precise sliding adjustment in the first horizontal direction.

[0059] Further, refer to Figures 1 to 2 In some embodiments of the utility model, the first sliding module 10 further includes a slide rail 14, and the other end of the mounting plate 21 is slidably arranged on the slide rail 14 through the first slider 13. Specifically, in addition to the second driving member 11, the first lead screw 12 and the first slider 13, the first sliding module 10 also includes a slide rail 14. The main purpose of this design is to enhance the stability and guidance of the mounting plate 21 during the sliding process. In practical applications, the other end of the mounting plate 21 is slidably arranged on the slide rail 14 through the first slider 13. In this way, when the second driving member 11 drives the first lead screw 12 to rotate, the first slider 13 will not only rotate and move on the first lead screw 12, but also slide linearly along the slide rail 14. This double sliding design ensures the stability and accuracy of the mounting plate 21 during the movement process, and prevents deviation or shaking caused by the movement. In addition, the addition of the slide rail 14 also provides an additional support point for the mounting plate 21, so that it can maintain a stable sliding state even when it is subjected to a large clamping force. This not only improves the clamping effect of the clamp, but also effectively extends the service life of the clamp.

[0060] Similarly, refer to Figures 1 to 2 In some embodiments of the utility model, the second sliding module 40 includes a third driving member 41, a second lead screw 42 and a second slider 43, the second lead screw 42 is connected to the output end of the third driving member 41, the second slider 43 is threadedly connected to the second lead screw 42, and the second clamping assembly 30 is arranged on the second slider 43.

[0061] The second sliding module 40 mainly includes a third driving member 41, a second lead screw 42, and a second slider 43. Among them, the second lead screw 42 is connected to the output end of the third driving member 41, so that the third driving member 41 can provide power for the second sliding module 40. The second slider 43 is threadedly connected to the second lead screw 42. When the second lead screw 42 rotates, the second slider 43 will slide linearly along the second lead screw 42. Specifically, the second clamping assembly 30 is arranged on the second slider 43. In this way, when the second slider 43 slides, the second clamping assembly 30 will also move accordingly. Since the sliding direction of the second sliding module 40 extends along the second horizontal direction, this design enables the second clamping assembly 30 to make precise sliding adjustments in the second horizontal direction to adapt to flexible printed circuit boards of different sizes and shapes.

[0062] In practical applications, the operator can control the third driving member 41 to drive the second sliding module 40 to work. When it is necessary to adjust the position of the second clamping assembly 30 in the second horizontal direction, just start the third driving member 41, and the second slider 43 can be driven to slide linearly through the rotation of the second lead screw 42, thereby driving the second clamping assembly 30 to make precise sliding adjustments in the second horizontal direction. To sum up, through the structure of the second sliding module 40, the circuit detection device for flexible printed circuit boards realizes the precise sliding adjustment of the second clamping assembly 30 in the second horizontal direction, further improving the flexibility and versatility of the fixture. This design enables the fixture to be more adaptable to flexible printed circuit boards of different sizes and shapes in practical applications, improving the processing efficiency and processing quality.

[0063] Referring to Figures 1 to 2 , in some embodiments of the present utility model, the circuit detection device for flexible printed circuit boards further includes a lifting assembly 60. The lifting assembly 60 is arranged on the frame and is located below the first clamping assembly 20 and the second clamping assembly 30. The lifting assembly 60 is respectively located between two groups of the first clamping assemblies 20 and between two groups of the second clamping assemblies 30. The lifting assembly 60 is used to lift the flexible printed circuit board so that the first clamping assembly 20 and the second clamping assembly 30 clamp the flexible printed circuit board.

[0064] In the embodiment of the present utility model, a jacking assembly 60 is further added to further improve the functionality and practicality of the fixture. The jacking assembly 60 is arranged on the frame and is located below the first clamping assembly 20 and the second clamping assembly 30. Specifically, the jacking assembly 60 is respectively located between the two groups of first clamping assemblies 20 and between the two groups of second clamping assemblies 30. Such a layout ensures that the jacking assembly 60 can evenly jack up the flexible printed circuit board, making it in close contact with the clamping assembly. In practical applications, when it is necessary to clamp the flexible printed circuit board, the operator first activates the jacking assembly 60. The jacking assembly 60 will move upward, jacking up the flexible printed circuit board to a position where it contacts the first clamping assembly 20 and the second clamping assembly 30. Subsequently, the operator activates the clamping assembly to tightly clamp the flexible printed circuit board. In this way, with the assistance of the jacking assembly 60, the clamping assembly can clamp the flexible printed circuit board more stably and accurately, avoiding the problem of unstable clamping caused by position deviation or loosening.

[0065] Specifically, referring to Figures 1 to 2 , in some embodiments of the present utility model, the jacking assembly 60 includes a top plate 61 and a lifting mechanism 62. The lifting mechanism 62 is arranged on the frame, and the top plate 61 is installed at the output end of the lifting mechanism 62. The lifting mechanism 62 is used to drive the top plate 61 to lift. The jacking assembly 60 mainly includes a top plate 61 and a lifting mechanism 62. The lifting mechanism 62 is firmly arranged on the frame, providing stable support and a power source for the jacking assembly 60. The top plate 61 is installed at the output end of the lifting mechanism 62, so that the movement of the lifting mechanism 62 can be directly transmitted to the top plate 61.

[0066] In practical applications, when it is necessary to jack up the flexible printed circuit board, the operator activates the lifting mechanism 62. The lifting mechanism 62 immediately starts to work, driving the top plate 61 to perform a lifting movement. Since the top plate 61 is in direct contact with the flexible printed circuit board, the lifting movement of the top plate 61 will directly act on the flexible printed circuit board, jacking it up to a position where it contacts the clamping assembly. The design of the lifting mechanism 62 fully considers the stability and accuracy during the jacking process. It can provide a smooth and continuous lifting movement to ensure that the top plate 61 does not deviate or shake during the jacking process. At the same time, the lifting mechanism 62 also has sufficient output force to easily handle flexible printed circuit boards of different weights and sizes.

[0067] The above has described the embodiments of the present utility model in detail with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art to which it pertains, various changes can be made without departing from the gist of the present utility model.
