[0029] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0030] Such as Figures 1-4As shown in the figure, the automatic winding device proposed by the present utility model includes a transmission mechanism 1, a bobbin assembly 2 driven by the transmission mechanism 1 to rotate, and a translation mechanism 3 driven by the transmission mechanism 1 to translate. The translation mechanism 3 includes a wire guide 31, a reciprocating lead screw 32 threadedly engaged with the top end of the wire guide 31, and a guiding optical rod 33 movably sleeved on the bottom end of the wire guide 31. Both ends of the reciprocating lead screw 32 and the guiding optical rod 33 are rotatably connected to the following fixed base 5 through bearing seats. In addition, the transmission mechanism 1 includes a first transmission wheel 11 coaxially and fixedly connected to the following first connecting shaft 213, a second transmission wheel 13 coaxially and fixedly connected to the reciprocating lead screw 32, and a transmission gear set 12 rotatably connected to the fixed base 5. The transmission gear set 12 is driven by a chain belt between the first transmission wheel 11 and the second transmission wheel 13, and an external motor is used to drive the first transmission wheel 11 or the transmission gear set 12 or the second transmission wheel 13 to rotate. Since the above structures are the prior art of the existing winding device, they will not be elaborated here.

[0031] In this embodiment, as Figure 2 shown, it includes at least a pair of yarn check mechanisms 4 installed on the wire guide 31 and translating with the wire guide 31. The yarn check mechanism 4 includes a fixed seat 41 fixedly connected to the wire guide 31 by bolts, a rotating rod 42 rotatably connected to the end of the fixed seat 41, a connecting arm 43 fixedly connected to the end of the rotating rod 42 at one end, a clamping cylinder 44 connected to the other end of the connecting arm 43, and a torsion spring 45 sleeved outside the rotating rod 42 and fixedly connected to the fixed seat 41 and the rotating rod 42 at both ends respectively. When the yarn 7 is cut off, the connecting arms 43 on the two yarn check mechanisms 4 clamp the yarn 7 under the elastic action of the torsion spring 45 as Figure 2 shown, so that the movable end of the yarn 7 will not easily retract, and this V-shaped clamping will not hinder the normal unwinding of the yarn 7.

[0032] In this embodiment, as Figure 3 shown, the bobbin assembly 2 includes a fixed cylinder part 21, a bobbin 22 detachably and snap-fittedly connected to the fixed cylinder part 21, and a movable cylinder part 23 connected to one end of the fixed cylinder part 21 for limiting the bobbin 22 on the fixed cylinder part 21;

[0033] Among them, the fixed cylinder part 21 includes a fixed cylinder edge plate 211, a fixed cylinder shaft 212 coaxially and fixedly connected to one end face of the fixed cylinder edge plate 211 and snap-fittedly sleeved with the bobbin 22, and a first connecting shaft 213 fixed to the other end face of the fixed cylinder edge plate 211 and coaxially and fixedly connected to the first transmission wheel 11. A pair of spline strips 2121 are integrally provided on the outer wall of the fixed cylinder shaft 212, and spline grooves 221 matching the spline strips 2121 are provided on the inner wall of the bobbin 22;

[0034] Among them, the movable cylinder part 23 includes a movable cylinder side plate 231, a movable cylinder shaft sleeve 232 fixed to one end face of the movable cylinder side plate 231 and sleeved on the end of the fixed cylinder shaft 212, and a second connecting shaft 233 fixed to the other end face of the movable cylinder side plate 231 and rotatably connected to the following movable part 52. The bobbin 22 is limited on the fixed cylinder part 21 by the movable cylinder part 23 and rotates together with the fixed cylinder part 21 by the engagement between the spline bar 2121 and the spline groove 221.

[0035] In this embodiment, as Figure 4 shown, it further includes a pair of fixed bases 5. One of the fixed bases 5 includes a fixed part 51, a movable part 52, a pair of guiding optical rods 53 with one end fixedly connected to the fixed part 51 and the other end movably passing through the movable part 52, and a threaded ring 54 threadedly engaged with the threaded part of the guiding optical rod 53 to limit the movable part 52. The horizontal sliding of the movable part 52 can be realized through the guiding optical rod 53, and then the movable cylinder part 23 is driven to slide horizontally, so as to facilitate the disassembly and assembly of the bobbin 22.

[0036] In this embodiment, it further includes a glue coating mechanism 6 for coating a glue line on the surface of the bobbin 22 to fix the movable end of the yarn 7. The glue coating mechanism 6 includes a glue coating box 61 fixedly connected to the fixed part 51 and a glue coating brush 62 arranged at the glue outlet of the glue coating box 61. The glue coating box 61 can adopt a traditional glue outlet device. A glue coating brush 62 is installed at its glue outlet. When the bobbin 22 is installed, since it is installed horizontally, the glue coating brush 62 will draw a glue line on the outer wall of the bobbin 22. After winding the movable end of the yarn 7 around the bobbin 22 and adhering it to the glue line, fixation can be achieved. When it is necessary to remove the bobbin 22 after the winding is completed, the soft bendability of the glue coating brush 62 itself enables it to still draw a glue line on the wound yarn 7 to fix the other movable end of the yarn 7 to prevent it from spreading. In other embodiments, the glue coating mechanism 6 can also be removed or designed to be vertically rotatable and reset, and only coat and draw lines when installing the bobbin 22, or choose an adhesive with low viscosity to ensure that the yarn 7 can be fixed while being easy to remove from the bobbin. This will not be elaborated here.

[0037] The working principle of this embodiment is: through the design of the yarn check mechanism 4, the movable end of the yarn 7 can be limited when the yarn 7 is cut off, preventing it from slipping out of the wire guide 31 and requiring re-threading;

[0038] Through the combined structure design of the bobbin assembly 2 and one of the fixed bases 5, the bobbin 22 can be quickly disassembled and replaced; through the design of the glue coating mechanism 6, the yarn 7 can be fixed when disassembling and assembling the bobbin 22, preventing problems such as inability to wind and spreading. Specifically, as Figure 4 shown, the movable part 52 is translated to one side to be separated from the fixed part 51, and the bobbin 22 is as Figure 3As shown, it is installed on the fixed cylinder member 21. During this process, the outer wall of the bobbin 22 moves relative to the glue brush 62, so that a glue line is drawn on the outer wall of the bobbin 22 through the glue brush 62. Then, the movable part 52 is moved back to its original position and limited by the threaded ring 54. The movable end of the yarn 7 is wound around the bobbin 22 and adhesively fixed to the above glue line.

[0039] The above specific embodiments are only several alternative embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
