Two groups of pressing plates 3211 are provided, and the two groups of pressing plates 3211 are arranged in a stacked manner. Each group of pressing plates 3211 includes a main body 32111 and a plurality of fins 32112 arranged on both sides of the main body 32111. The multiple fins 32112 on each side of the main body 32111 are arranged at intervals along the X direction, and the fins 32112 on both sides of the main body 32111 are staggered so that the fiber line can be spirally wound; the support bar 3212 is provided between the two groups of pressing plates 3211 and is corresponding to the main body 32111. First mounting holes are provided at both ends of the support bar 3212, and second mounting holes are provided at both ends of the two groups of pressing plates 3211. The fixing parts pass through the corresponding first mounting holes and second mounting holes to fix the two groups of pressing plates 3211 and the support bar 3212 in connection. A plurality of support sheets 3213 are provided, and the plurality of support sheets 3213 are provided between the two groups of pressure plates 3211 and are located on one side of the support bar 3212. Each support sheet 3213 is provided in one-to-one correspondence with the fins 32112 on the corresponding side of the two groups of pressure plates 3211. A first fixing hole is provided on the support sheet 3213, and a second fixing hole is provided on the two groups of pressure plates 3211. The fixing member passes through the corresponding first fixing hole and the second fixing hole to fix the support sheet 3213 between the two groups of pressure plates 3211. A gap is formed between the support sheet 3213 and the support bar 3212 to form an accommodation space 3210 for clamping the spring coil (see Figure 8 ). When the clamping assembly 321 is assembled, the spring coil extends from one end of the clamping assembly 321 into the accommodating space 3210 through the clamping claw, and the spring coil is pulled into the accommodating space 3210 through the clamping claw. The clamping claw extends from the other end of the accommodating space 3210, and the spring coil is clamped in the accommodating space 3210. In order to prevent the spring coil from moving, a clamping plate can be inserted into the gap between the fins 32112 on one side of the supporting sheet 3213 to fix the spring coil. The method of fixing the spring coil by the clamping plate belongs to the prior art and will not be described in detail here.

[0084] After the fiber line is wound onto the clamping assembly 321, the fiber line can be cut along the gap between the pressing plates 3211 on the side where the supporting pieces 3213 are not installed. When the clamping assembly 321 is disassembled, the fiber line clamp is set in the pitch gap of the spring coil. The length of the fiber line on the spring coil can be controlled by replacing the clamping assembly 321 of different sizes.

[0085] Furthermore, the width of the fin 32112 gradually increases in a direction approaching the main body 32111. In the present embodiment, the structure of the fin 32112 is a trapezoidal structure, which is conducive to better insertion of the fiber line into the gap of the spring coil.

[0086] Alternatively, if Figure 1 and Fig.11As shown, the spring coil winding device also includes a visual system 4, which is used to detect whether the fiber wire is pressed into the preset pitch gap of the spring coil.

[0087] Specifically, the visual system 4 includes a visual support frame 41, a camera 42 and a light source 43. The visual support frame 41 is arranged at the output end of the driving device 21 or arranged on the weaving system 2; the camera 42 is installed on the visual support frame 41; the light source 43 is installed on the visual support frame 41, the light source 43 is located below the camera 42, and is arranged opposite to the camera head of the camera 42, and the light source 43 is an annular structure. Through the visual system 4, it is possible to detect whether the fiber line is pressed into the preset pitch gap of the spring coil to correct the winding error; the camera 42 is used to collect images during the winding process to determine whether the fiber line is pressed into the preset pitch gap of the spring coil, and the light source 43 can provide light for the image collection and improve the clarity of the image; the light source 43 of the annular structure avoids interference with the image collection of the camera 42. It should be noted that the visual system 4 is not limited to detection by the camera 42, and can also be other detection methods, as long as it can identify whether the fiber line is pressed into the preset pitch gap of the spring coil.

[0088] Preferably, the position and angle of the camera 42 can be adjusted through the visual support frame 41, and the position and angle of the light source 43 can also be adjusted through the visual support frame 41 to adapt to different usage scenarios.

[0089] Optionally, the spring coil winding device further includes a control system 5, and the visual system 4, the braiding system 2 and the winding system 3 are all connected to the control system 5. Specifically, the camera 42 and the light source 43 of the visual system 4, the rotating motor 331, the winding motor, the first driving mechanism 211 and the second driving mechanism 212 are all connected to the control system 5, and the control system 5 controls the actions of each component.

[0090] During operation, the camera 42 transmits the photographs of the fiber line wound by the winding system 3 to the control device. If the multiple strands of fiber line are only pressed into the same pitch gap of the spring coil, the control system 5 controls the various components to continue working; if the multiple strands of fiber line are pressed into different pitch gaps, it means that the tightness of the fiber line is too loose, then the control system 5 controls the rotating motor 331 to reverse and speed up the winding motor to make the multiple strands of fiber line more tightly woven, and then controls the rotating motor 331 to rotate forward again to press the fiber line into the gap of the spring coil until all windings are completed.

[0091] Operation process:

[0092] (1) The spring ring is inserted into the accommodation space 3210 of the clamping assembly 321, and then the clamping assembly 321 is fixed in the grooves 3221 of the two sets of mounting seats 322 and compressed with a locking member;

[0093] (2) Manually control the winding motor to weave and tighten the multiple strands of fiber wool, and the wound fiber line passes through the two guide wheels 242 in turn to be tensioned and then passes through the wire tube 232;

[0094] (3) The outlet position of the braiding mechanism 22 is adjusted by the second driving mechanism 212 so that the outlet is 20 mm away from the outer edge of the clamping assembly 321, and the drawn fiber line is wound around the fixing piece of the clamping assembly 321 for 2-3 turns to fix the free end of the fiber line;

[0095] (4) Adjust the rotation speed of the rotating motor 331 and the moving speed of the first driving mechanism 211, and change the working mode of the winding motor to automatic, and set the moving speed of the first driving mechanism 211;

[0096] (5) Start the light source 43 and the camera 42, take photos of the multiple strands of fiber hair pressed into the pitch gap of the spring coil in real time, and judge. When the multiple strands of fiber hair are pressed into only one pitch gap, the equipment continues to operate normally; when the multiple strands of fiber hair are pressed into only multiple pitch gaps, the control system 5 controls the rotating motor 331 to reverse, controls the winding motor to speed up, so that the multiple strands of fiber hair are woven more tightly, and then controls the rotating motor 331 to rotate forward again to press the multiple strands of fiber hair until all windings are completed.

[0097] (6) When the winding is completed, remove the clamping assembly 321 and use a blade to cut the fiber line along the gap between the two sets of pressing plates 3211 on one side of the unsupported loose piece 3213 of the clamping assembly 321, and remove the spring coil with the fiber hair, thus completing the winding of the fiber hair.
