[0023] like Figures 1 to 4As shown, a clamping device for a bobbin comprises a clamping arm 1 arranged at both ends of the bobbin, and one end of each of the two clamping arms 1 is connected to a positioning member 2 for abutting the bobbin; the two clamping arms 1 are both connected to the flip structure 3, and the flip structure 3 can drive the clamping arms 1 to rotate; at least one of the two clamping arms 1 is connected to the flip structure 3 through a translation structure 4, and the translation structure 4 is used to adjust the distance between the two clamping arms 1; at least one of the two clamping arms 1 is connected to a rotating structure 5, and the rotating structure 5 can drive the bobbin to rotate to achieve winding.

[0024] The present application realizes the adjustment of the distance between the two clamping arms 1 through a translation structure, thereby realizing the function of the clamping arm 1 to clamp the bobbin, and the positioning member 2 can fix the bobbin more specifically, ensuring a better clamping effect, deepening the degree of automation of the winding work, and improving production efficiency.

[0025] The flip structure 3 includes a flip platform 31, a flip bracket 32 ​​rotatably connected to at least one end of the flip platform 31, and a flip drive assembly 33 that drives the flip platform 31 to rotate; the flip drive assembly 33 includes a first driven wheel 331, a first driving wheel 332 that drives the first driven wheel 331 to rotate, and a first driving member that drives the first driving wheel 332 to rotate; at least one end of the flip platform 31 is connected to the first driven wheel 331, and both the first driven wheel 331 and the first driving wheel 332 are rotatably connected to the flip bracket 32.

[0026] The clamping arms 1 are all connected to the flip platform 31. The rotation of the flip platform 31 drives the clamping arms 1 to rotate, thereby transferring the bobbin from the working area to the non-working area, thereby realizing the function of automatic unloading.

[0027] In the present application, the first driven wheel 331 and the first driving wheel 332 are driven by a synchronous belt. In other embodiments, the first driven wheel 331 and the first driving wheel 332 can also be driven by direct engagement.

[0028] Furthermore, a limiting groove 321 is provided on the flip bracket 32, and a limiting column 3311 is provided on the first driven wheel 331. The limiting column 3311 is at least partially located in the limiting groove 321. The cooperation between the limiting groove 321 and the limiting column 3311 determines the angle at which the first driven wheel 331 can rotate.

[0029] The cooperation between the limiting groove 321 and the limiting column 3311 limits the rotation angle of the flip platform 31 to prevent the clamping arm 1 from rotating excessively.

[0030] The translation structure 4 includes a guide rail 41 fixed on the flip structure 3 and a slider 42 slidably connected to the guide rail 41 , and the number of the slider 42 is at least one; at least one of the two clamping arms 1 is connected to the slider 42 .

[0031] By driving the slider 42 to move on the guide rail 41 , the distance between the two clamping arms 1 can be adjusted, thereby achieving clamping of the bobbin, and is applicable to bobbins of various specifications.

[0032] Furthermore, the slider 42 is connected to a fastener, which fastens the slider 42 to the guide rail 41 so that the slider 42 cannot move relative to the guide rail 41; the slider 42 is connected to a clamping drive assembly 44, and the clamping drive assembly 44 includes a hinged seat 441 connected to the slider 42 and a driving cylinder 442, the middle part of the clamping arm 1 is hinged to the hinged seat 441, one end of the driving cylinder 442 is connected to the slider 42, and the other end is connected to the clamping arm 1.

[0033] In this embodiment, the slider 42 is fixed to the guide rail 41 by fasteners according to the size of the bobbin, and then the clamping arm 1 is driven to rotate relative to the hinge seat 441 by the clamping drive assembly 44, and can perform opening and closing actions, thereby clamping the bobbin; when clamping the bobbin, the two clamping arms 1 are first driven to open the opening, and when the bobbin or the clamping arm moves to the specified position, the clamping arm 1 is driven to close the opening, thereby clamping the bobbin; after the bobbin is wound, the rotation of the flip platform 31 drives the clamping arm 1 to rotate, transferring the bobbin from the working area to the non-working area, and then driving the two clamping arms 1 to open the opening, and the bobbin that has been wound will automatically fall off, realizing the function of automatic unloading.

[0034] The rotating structure 5 includes a rotating drive member 51 and a rotating shaft 52 connected to the clamping arm 1. One end of the rotating shaft 52 is connected to the clamping arm 1, and the other end is connected to the positioning member 2. The rotating drive member 51 is used to drive the rotating shaft 52 to rotate.

[0035] Furthermore, the rotary drive member 51 and the rotary shaft 52 are connected to each other via a transmission assembly; the clamping arm 1 is also connected to a detection structure for detecting the winding progress.

[0036] In this embodiment, the transmission component adopts sprocket transmission, which has a good transmission effect and can control the winding process by controlling the number of rotations of the driving wheel motor. In other embodiments, belt transmission can also be used. If the output line is stuck during the winding process, the line can be prevented from being broken by slipping, thereby ensuring a better winding effect.

[0037] Through the detection structure, when it is detected that the amount of thread on the bobbin meets the requirement, the winding can be automatically stopped and the next step can be carried out to realize automated production and ensure uniform winding.

[0038] Among them, the detection structure can be a mass sensor that detects based on weight. When the mass of the thread on the bobbin reaches a preset value, it is judged that the winding is completed; it can also be a light sensor that detects the winding diameter, such as an infrared sensor. One of the clamping arms 1 is provided with a transmitting end, and the other clamping arm 1 is provided with a receiving end. If the receiving end cannot receive the light from the transmitting end, the thread on the bobbin blocks the light, and it is judged that the winding is completed.

[0039] At least one of the two clamping arms 1 is connected to a thread clamping structure 6, which is used to clamp the thread before winding.

[0040] The wire clamping structure 6 includes a plate body 61 for clamping the wire, a wire clamping drive assembly 62 is connected to the plate body 61 , and a buffer pad 21 is provided on the contact surface between the positioning member 2 and the plate body 61 .

[0041] The thread end is clamped by the positioning member 2 and the plate 61, which ensures that the thread will not slide relative to the thread drum in the early stage of winding, thereby ensuring a better winding effect.

[0042] In order to ensure that the positioning member 2 and the clamping structure 6 can rotate synchronously, a guide column 22 is further connected between the positioning member 2 and the clamping structure 6. The guide column 22 can play a transmission role, further ensuring that the positioning member 2 and the clamping structure 6 can rotate synchronously.

[0043] In this embodiment, the buffer pad 21 is made of rubber, which can not only buffer the impact between the two plates 61 and extend the service life of the plates, but also increase the friction between the contact surfaces and clamp the thread ends well.

[0044] Furthermore, the wire clamping drive assembly 62 includes an electromagnetic component 621 and a magnetic component 622 connected to the corresponding plate body 61, and the electromagnetic component 621 can attract the plate body 61 connected to the magnetic component 622; the wire clamping drive assembly 62 also includes a spring 623; one end of the spring 623 abuts against the magnetic component 622 or the plate body 61, and the spring 623 can push the plate body 61 away from the electromagnetic component 621.

[0045] In this embodiment, the electromagnetic component 621 cooperates with the magnetic component 622 to drive the movement of the plate body. When the electromagnetic component 621 is energized, it will attract the plate body 61 with the magnetic component 622, so that there is a gap between the two plate bodies 61, and the thread end is sent into the gap through the cooperation of other structures; when the thread end is sent into the gap, the electromagnetic component 621 is de-energized, and the plate body 61 with the magnetic component 622 will move away from the electromagnetic component 621 under the action of the spring 623, and abut against the other plate body 61, thereby clamping the thread end.

[0046] It should be noted that the above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above embodiments, it should be understood by those skilled in the art that the present invention can still be modified or replaced by equivalents, and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
