The other end of the flexible flat cable 30 is in communication with a plug-in interface of the to-be-rotated component 70, so that the power provided by the industrial control mechanism 80 sequentially flows through the adapter port 122, the flexible flat cable 30, the first port 211, the power passing interface, the second port 221, the flexible flat cable 30, and the plug-in interface (not shown in the figure) of the to-be-rotated component 70, thereby supplying power to the to-be-rotated component 70.

[0047] As shown in Figure 7As shown, in the embodiment, the first power supply end 21 and the second power supply end 22 are both installed on the mounting position 111 of the side surface of the rotating shaft 11, that is, the first power supply end 21 and the second power supply end 22 both rotate with the rotation of the rotating shaft 11, and the rotating shaft 11 is arranged to rotate to drive the to-be-rotated component 70 to rotate, so that the to-be-rotated component 70 rotates simultaneously with the second power supply end 22, that is, both are relatively static, that is, the cable path of the flexible flat cable 30 connected to the second power supply end 22 and the plug-in interface will not be wound with the rotation of the rotating shaft 11.

[0048] In a further embodiment, the width ratio of the limiting strip row 40 to the flexible flat cable 30 is any value in the range of 1.1-1.5, that is, the width ratio of the limiting strip row 40 to the flexible flat cable 30 can be 1.1, 1.15, 1.2, 1.25, 1.3, 1.35, 1.4, 1.45 or 1.5, or any value in the range of 1.1-1.5. In the embodiment, the width of the limiting strip row 40 is always greater than the width of the flexible flat cable 30, and the width ratio of the limiting strip row 40 to the flexible flat cable 30 is in the above range, so that the limiting strip row 40 arranged between the adjacent two flexible flat cables 30 can isolate the flexible flat cables 30, so that the adjacent two flexible flat cables 30 do not contact when rotating around the rotating shaft 11, that is, the anti-wear performance of the cable anti-winding device 100 is further improved.

[0049] In a further embodiment, the material of the limiting strip row 40 is any one of polyethylene, polypropylene, polystyrene or polycarbonate. In the embodiment, the material of the limiting strip row 40 can be any one of polyethylene, polypropylene, polystyrene or polycarbonate, because the limiting strip row 40 made of polyethylene, polypropylene, polystyrene or polycarbonate not only has strong flexibility, but also has high wear resistance, so that the limiting strip row 40 can tightly fit the corresponding flexible flat cable 30 when winding around the rotating shaft 11, thereby completely isolating the flexible flat cable 30.

[0050] As shown in the drawings, Figure 5As shown, in a further embodiment, the limiting strip row 40 is provided with a limiting block 41 at one end away from the first power supply end 21, and the adapter assembly 12 further comprises a plurality of first fixing members 123 corresponding to the limiting strip row 40, each first fixing member 123 is arranged at the corresponding adapter port 122, and the first fixing member 123 comprises a through hole 124 extending in the vertical direction and a limiting hole 125 at the top end for limiting the limiting block 41. In this embodiment, each adapter port 122 of the adapter assembly 12 is provided with a first fixing member 123, the through hole 124 of the first fixing member 123 penetrates the limiting strip row 40, and the top of the first fixing member 123 is provided with a limiting hole 125 for limiting the limiting block 41 at the end of the limiting strip row 40, so that when the rotating shaft 11 rotates to drive the flexible flat cable 30 and the limiting strip row 40 to wind around the rotating shaft 11, the limiting strip row 40 gradually releases along the through hole 124 towards the rotating shaft 11, so as to increase the rotating stroke of the limiting strip row 40 and the flexible flat cable 30, thereby increasing the rotating angle range of the rotating shaft 11 while preventing the flexible flat cable 30 from being wound.

[0051] As shown in the drawings, Figure 5 In a further embodiment, the first fixing member 123 comprises a vertical portion 126 and a protruding portion 127, the through hole 124 is formed in the interior of the vertical portion 126, the protruding portion 127 is located at the top end of the vertical portion 126 and protrudes from the top end of the vertical portion 126 towards the end away from the vertical portion 126, and the limiting hole 125 is formed in the protruding portion 127, and the limiting block 41 of the limiting strip row 40 is arranged at the top of the protruding portion 127 to limit the length of the limiting strip row 40, so that the length of the limiting strip row 40 meets the maximum rotating stroke of the flexible flat cable 30 when the rotating shaft 11 rotates, and at the same time, the limiting block 41 is engaged with the limiting hole 125 when the maximum stroke of the flexible flat cable 30 is reached to stop the rotation of the rotating shaft 11, preventing the flexible flat cable 30 from being torn off due to excessive rotation of the rotating shaft 11.

[0052] As shown in the drawings, Figure 6 In a further embodiment, the adapter assembly 12 further comprises a plurality of second fixing members 128 corresponding to the flexible flat cable 30, each second fixing member 128 is provided with a through hole 129 for penetrating the flexible flat cable 30, and the second fixing member 128 is in a pipe clamp structure, and the second fixing member 128 is arranged at the corresponding adapter port 122, and the second fixing member 128 is arranged in a pipe clamp structure to clamp the flexible flat cable 30 and lock the second fixing member 128 by screws and nuts, thereby limiting and positioning the corresponding flexible flat cable 30, and at the same time, the pipe clamp structure can be flexibly adjusted according to the width or diameter of the flexible flat cable 30, so that the second fixing member 128 can be applied to flexible flat cables 30 of various sizes.

[0053] AsFigure 4 As shown, in this embodiment, the cable anti-tangling device 100 further includes a clamping member 60, which is sleeved on the end of all the limiting strips 40 and all the flexible flat cables 30 near the first power supply terminal 21. In this embodiment, the clamping member 60 is configured to fix and clamp all the limiting strips 40 and all the flexible flat cables 30, so as to provide a second force point for all the limiting strips 40 and all the flexible flat cables 30. When the rotating shaft 11 rotates and causes all the limiting strips 40 and all the flexible flat cables 30 to become entangled, it can prevent the tension generated by the rotation from causing the flexible flat cables 30 to fall off from the first port 211, thereby further improving the structural stability of the cable anti-tangling device 100.

[0054] In a further embodiment, the drive source 50 is a servo motor. The servo motor can precisely control its position, speed and acceleration to achieve high-precision motion control and has excellent response speed. It can start, stop and reverse quickly to meet the needs of high-speed motion and frequent start and stop. It has strong anti-abnormal and anti-disturbance performance and good stability. The drive source 50 is set as a servo motor, which can not only meet the rotation angle requirements of the rotating part 70, but also meet its controllable rotation stroke, while improving the high-precision control requirements of the cable anti-tangling device 100.

[0055] like Figure 1 As shown, in this embodiment, the cable anti-tangling device 100 also includes a transmission mechanism. The transmission mechanism includes two synchronous pulleys and a synchronous belt connected to the two pulleys. One synchronous pulley is connected to the end of the rotating shaft 11 away from the adapter assembly 12, and the other synchronous pulley is connected to the drive source 50. This allows the drive source 50 to drive one synchronous pulley to rotate, which in turn drives the synchronous belt and the other synchronous pulley, thereby rotating the rotating shaft 11. In other words, the synchronous belt drive relies on the meshing of the pulleys and the synchronous belt to transmit motion and power, ensuring an accurate transmission ratio, effectively improving transmission efficiency, and enabling more efficient utilization of input power, thus improving resource utilization. Simultaneously, the synchronous belt drive system has a compact structure and smooth operation, reducing energy consumption and noise levels, thereby improving the structural stability of the cable anti-tangling device 100. Here, the cable anti-tangling device can be applied to verification equipment for MEMS sensors.

[0056] In this embodiment, the working principle of the cable anti-tangling device 100 is as follows: the rotating shaft 11 of the rotating mechanism 10 is rotated in a controlled manner, driving the first power supply end 21, the second power supply end 22 and the component to be rotated 70 to rotate, so as to meet the rotation angle requirements of the component to be rotated 70. When the rotating shaft 11 rotates, the flexible flat cable 30 connecting the first port 211 of the first power supply end 21 and the adapter port 122 of the adapter component 12 rotates and winds around the rotating shaft 11. The presence of the limiting strip 40 makes the flexible flat cables 30 have no contact, thereby preventing the flexible flat cables 30 from tangling and wearing.

[0057] Any combination of the technical features in the above-described embodiments can be made, and for the sake of brevity, not all possible combinations are described, however, as long as the combination of the technical features does not exist in contradiction, it shall be considered as within the scope of the present disclosure.

[0058] The above-described embodiments only express several implementation manners of the present application, the description is relatively specific and detailed, but it shall not be understood as a limitation on the scope of the present application patent. It should be pointed out that, for ordinary skilled in the art, under the premise of not departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application patent shall be subject to the appended claims.
