A glass fiber strand winding assembly

Abstract

This utility model relates to the field of glass fiber tube production technology, and in particular to a glass fiber bundle winding assembly. It includes a frame, a winding reel horizontally rotatably connected to the frame, multiple connecting shafts evenly distributed around the winding reel's rotation axis and horizontally rotatably connected to the winding reel, multiple unwinding drums fixed one-to-one on the connecting shafts with their centerlines perpendicular to the winding reel's centerline, a first servo motor mounted on the frame for driving the winding reel's rotation, and an adjustment device mounted on the frame for driving the multiple connecting shafts to rotate synchronously relative to the winding reel, thereby fixing the angle between the centerlines of the multiple unwinding drums and the horizontal plane.

Description

Technical Field

[0001] This utility model relates to the field of glass fiber tube production technology, and in particular to a glass fiber wire harness winding assembly. Background Technology

[0002] Fiberglass tubes are typically produced using a fiber winding process, which involves winding bundles of fiberglass threads onto a rotating mold in a specific pattern to form a tubular structure. During the winding process, the fiberglass bundles are impregnated with resin to enhance the tube's strength and durability. This process enables continuous production of fiberglass tubes and offers advantages such as high production efficiency and consistent product quality.

[0003] In the production of fiberglass tubes, the multi-strand fiberglass winding process is a common method. This process is achieved by a rotating winding reel driving multiple unwinding drums, each containing a coil of fiberglass strands. The rotation of the winding reel pulls the fiberglass out of the unwinding drums and winds it onto a mold according to a specific pattern, thus forming the main structure of the fiberglass tube. This process improves production efficiency and ensures the quality and performance of the fiberglass tubes.

[0004] In multi-strand glass fiber winding processes, the unwinding drum and winding reel are connected by a rotating mechanism to prevent inversion. Under gravity, the opening of the unwinding drum faces upwards, effectively preventing the rolled glass fiber bundle from tipping out. However, in actual production, if the unwinding speed is too high, the unwinding drum will swing significantly, resulting in large fluctuations in the unwound glass fiber bundle. This fluctuation affects the uniform winding of the glass fiber, thus reducing the winding quality of the glass fiber tube. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a glass fiber wire harness winding assembly that can improve the winding quality of glass fiber tubes.

[0006] To solve the above-mentioned technical problems, the present invention provides a glass fiber wire harness winding assembly, including a frame, a winding disc horizontally rotatably connected to the frame, multiple connecting shafts evenly distributed around the circumference of the winding disc's rotation axis and horizontally rotatably connected to the winding disc, multiple unwinding drums fixed one-to-one on the multiple connecting shafts with their axis lines perpendicular to the winding disc's axis line, a first servo motor mounted on the frame for driving the winding disc's rotation, and an adjustment device mounted on the frame for driving the multiple connecting shafts to rotate synchronously relative to the winding disc so that the angle between the axis lines of the multiple unwinding drums and the horizontal plane is fixed.

[0007] As an improvement to the above solution, multiple unwinding drums are arranged one-to-one on the front side of the connecting shaft, and the center lines of the multiple unwinding drums are coplanar.

[0008] As an improvement to the above solution, the adjustment device includes an adjustment disc that is horizontally rotatably connected to the frame and whose rotation axis is coaxial with the rotation axis of the winding disc, a plurality of adjustment gears that are fixed one-to-one with each other on the rear side of the connecting shaft, an annular rack fixed to the adjustment disc and meshing with the plurality of adjustment gears, and a second servo motor mounted on the frame for driving the adjustment disc to rotate. The rotation axis of the adjustment disc, the rotation axis of the annular rack and the rotation axis of the winding disc coincide, and the rotation axis of the plurality of adjustment gears coincides with the rotation axis of the plurality of connecting shafts.

[0009] As an improvement to the above scheme, the outer side of the annular rack meshes with the outer sides of multiple adjusting gears, and the adjusting disc rotates in the same direction as the winding disc.

[0010] As an improvement to the above solution, the first servo motor is connected to the winding disc via a first belt drive mechanism, and the second servo motor is connected to the adjustment disc via a second belt drive mechanism.

[0011] As an improvement to the above solution, the winding disc is provided with a first clearance through hole, and the adjusting disc is provided with a second clearance through hole.

[0012] As an improvement to the above solution, the axis of the unwinding drum is perpendicular to the horizontal plane.

[0013] As an improvement to the above solution, the unwinding drum is provided with a unwinding hole on the side away from the connection with the connecting shaft, with the axis of rotation of the connecting shaft coinciding with the axis of rotation of the connecting shaft.

[0014] As an improvement to the above solution, the unwinding drum is also equipped with two sets of clamping mechanisms for clamping the rolled glass fiber bundles. The clamping mechanism includes an arc-shaped plate for abutting against the outer side of the glass fiber bundle, multiple guide rods spaced vertically and slidably connected to the unwinding drum, and multiple compression springs corresponding to each other and sleeved on the outer side of the guide rods. The two sides of the compression springs are respectively used to abut against the inner side of the unwinding drum and the outer side of the arc-shaped plate.

[0015] As an improvement to the above solution, the clamping mechanism further includes a vertical tie rod located outside the unwinding drum and fixed to the outer ends of multiple guide rods.

[0016] The present invention has the following beneficial effects:

[0017] This utility model discloses a glass fiber bundle winding assembly. Through the cooperation of a frame, winding disc, multiple connecting shafts, multiple unwinding drums, a first servo motor, and an adjustment device, even if the winding disc rotates at a high speed during the production process, the angle between the axis of the multiple unwinding drums and the horizontal plane remains unchanged as the winding disc drives the connecting shafts to rotate. This greatly reduces the swaying amplitude of the unwinding drums caused by their high-speed rotation, resulting in smaller fluctuations in the unwound glass fiber bundles. This makes the winding of the glass fiber bundles more uniform and improves the winding quality of the glass fiber tubes. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of this application implemented as described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] like Figures 1 to 10As shown, a glass fiber wire harness winding assembly in this embodiment of the present invention includes a frame 100, a winding disc 200 rotatably connected to the frame 100, multiple connecting shafts 300 evenly distributed around the circumference of the rotating axis of the winding disc 200 and rotatably connected to the winding disc 200, multiple unwinding drums 400 fixed one-to-one on the multiple connecting shafts 300 with their axis perpendicular to the axis of the winding disc 200, a first servo motor 500 mounted on the frame 100 for driving the winding disc 200 to rotate, and an adjustment device 600 mounted on the frame 100 for driving the multiple connecting shafts 300 to rotate synchronously relative to the winding disc 200 so that the angle between the axis of the multiple unwinding drums 400 and the horizontal plane is fixed.

[0041] In fact, the winding disc 200 can be connected to the machine horizontally via an arc-shaped groove, that is, the rotation axis of the winding disc 200 is parallel to the horizontal plane, and the winding disc 200 rotates under the drive of the first servo motor 500; the unwinding drum 400 is used to hold the rolled glass fiber bundles. During the production process of the glass fiber tube, the glass fiber bundles in the unwinding drum 400 are pulled out and wound onto the resin on the outer guide tube, thereby forming the glass fiber tube.

[0042] It should be noted that the adjustment device 600 can be adjusted by means of belt drive, gear drive and sprocket drive. For example, when the first servo motor 500 drives the winding disc 200 to rotate clockwise by 90 degrees, the adjustment device 600 can drive multiple connecting shafts 300 to rotate counterclockwise by 90 degrees at the same time, which cancels out the clockwise rotation of the unwinding drum 400 by 90 degrees, so that the angle between the axis of the multiple unwinding drums 400 and the horizontal plane remains unchanged.

[0043] This utility model discloses a glass fiber bundle winding assembly. Through the cooperation of a frame 100, a winding disc 200, multiple connecting shafts 300, multiple unwinding drums 400, a first servo motor 500, and an adjustment device 600, during the production process, even if the winding disc 200 rotates at a high speed, the angle between the axis of the multiple unwinding drums 400 and the horizontal plane remains unchanged as the winding disc 200 drives the connecting shafts 300 to rotate. This greatly reduces the swaying amplitude of the unwinding drums 400 caused by their high-speed rotation, resulting in smaller fluctuations in the unwound glass fiber bundles. This makes the winding of the glass fiber bundles more uniform and improves the winding quality of the glass fiber tubes.

[0044] Specifically, the multiple unwinding drums 400 are preferably arranged one-to-one with each other on the front side of the connecting shaft 300. The centerlines of the multiple unwinding drums 400 are coplanar, which makes the spatial distribution of the unwinding drums 400 more reasonable, facilitating the orderly unwinding and winding of the glass fiber bundle. Since the centerlines of the unwinding drums 400 are coplanar, the glass fiber bundle is subjected to more uniform force during the unwinding process, avoiding tension fluctuations in the bundle caused by uneven force, thereby improving the uniformity and consistency of winding.

[0045] It is worth mentioning that the adjustment device 600 preferably includes an adjustment disc 610 horizontally rotatably connected to the frame 100 and whose rotation axis is coaxial with the rotation axis of the winding disc 200; a plurality of adjustment gears 620 fixed one-to-one with each other on the rear side of the connecting shaft 300; an annular rack 630 fixed to the adjustment disc 610 and meshing with the plurality of adjustment gears 620; and a second servo motor 640 mounted on the frame 100 for driving the adjustment disc 610 to rotate. The rotation axes of the adjustment disc 610 and the annular rack 630 coincide with the rotation axis of the winding disc 200, and the rotation axes of the plurality of adjustment gears 620 coincide with the rotation axes of the plurality of connecting shafts 300. Since the adjustment gears 620 are fixed on the rear side of the connecting shaft 300, the angle between the adjustment gears 620 and the unwinding drum 400 remains unchanged, providing a basis for controlling the angle of the unwinding drum 400. During the unwinding process, to maintain the angle of the unwinding drum 400, it is only necessary to keep the adjusting gear 620 stationary relative to the frame 100. For example, when the winding disc 200 rotates 90 degrees clockwise, the ring rack 630 drives the adjusting gear 620 to rotate 90 degrees counterclockwise. If the transmission ratio between the ring rack 630 and the adjusting gear 620 is 1:2, then the second servo motor 640 drives the adjusting disc 610 to rotate the ring rack 630 by 45 degrees, ensuring that the angle of the unwinding drum 400 remains stable throughout the winding process, improving the uniformity and stability of the glass fiber bundle winding, and thus enhancing the winding quality of the glass fiber tube.

[0046] Furthermore, the outer side of the annular rack 630 preferably meshes with the outer sides of multiple adjusting gears 620, so that the annular rack 630 and the adjusting disc 610 combine to form a driving gear, driving multiple adjusting gears 620 as driven gears to rotate, thereby achieving a stable transmission effect. The adjusting disc 610 rotates in the same direction as the winding disc 200. When the winding disc 200 rotates clockwise, the adjusting disc 610 also rotates clockwise. Through the meshing of the annular rack 630 and the adjusting gears 620, the adjusting gears 620 can rotate counterclockwise relative to the winding disc 200, thereby counteracting the clockwise rotation of the unwinding drum 400 and keeping the angle between the axis of the unwinding drum 400 and the horizontal plane unchanged.

[0047] Specifically, the first servo motor 500 is preferably connected to the winding reel 200 via a first belt drive mechanism 510, and the second servo motor 640 is preferably connected to the adjusting disc 610 via a second belt drive mechanism 641. This avoids misalignment between the ring rack 630 and the multiple adjusting gears 620, thus preventing interference between the first servo motor 500 driving the winding reel 200 and the second servo motor 640 driving the adjusting disc 610, and the ring rack 630 driving the multiple adjusting gears 620. This achieves the unwinding function of the winding reel 200 and the adjustment function of the adjusting disc 610. Furthermore, the frame 100 has openings at the rotatable connection points with the winding reel 200 and the adjusting disc 610 to prevent interference between the frame 100 and the first belt drive mechanism 510 or the second belt drive mechanism 641.

[0048] It should be noted that the winding disc 200 is preferably provided with a first clearance through hole 210, and the adjusting disc 610 is preferably provided with a second clearance through hole 611. The first clearance through hole 210 and the second clearance through hole 611 are used to allow the external guide tube to pass through, so as to ensure that the resin on the guide tube is wound with glass fiber wire bundle.

[0049] In a preferred embodiment of the present invention, the axis of the unwinding drum 400 is preferably perpendicular to the horizontal plane, which ensures that the rolled glass fiber bundle can be stably placed in the unwinding drum 400, thereby maintaining stability during the unwinding process.

[0050] It is worth mentioning that the unwinding drum 400 preferably has a wire unwinding hole 410 on the side away from the connection with the connecting shaft 300, with the axis of the unwinding hole 410 coinciding with the axis of rotation of the connecting shaft 300. This makes the wire unwinding holes 410 in the multiple unwinding drums 400 evenly distributed around the axis of rotation of the winding disc 200. During the unwinding process of the glass fiber bundle, the glass fiber bundle of resin wound onto the external guide tube is more evenly distributed, further improving the uniformity of winding.

[0051] Furthermore, the unwinding drum 400 preferably also has two sets of clamping mechanisms 700 for clamping the wound glass fiber bundles. Each clamping mechanism 700 includes an arc-shaped plate 710 that abuts against the outer side of the glass fiber bundle, multiple guide rods 720 spaced vertically and slidably connected to the unwinding drum 400, and multiple compression springs 730 correspondingly sleeved on the outer side of the guide rods 720. The compression springs 730 abut against the inner side of the unwinding drum 400 and the outer side of the arc-shaped plate 710 on their respective sides. During unwinding, as the wound glass fiber bundle gradually decreases in size, the arc-shaped plate 710 moves along the guide rods 720 towards the center of the unwinding drum 400 to accommodate changes in the outer diameter of the bundle. The guide rods 720 ensure smooth and straight movement of the arc-shaped plate 710, preventing deviation. The compression springs 730 push the arc-shaped plate 710 to move, thereby maintaining the clamped glass fiber bundle. The above structure effectively prevents the wire harness from shaking within the unwinding drum 400, reduces unwinding instability caused by changes in wire harness diameter, and improves unwinding stability and winding uniformity.

[0052] Furthermore, the clamping mechanism 700 preferably includes a vertical pull rod 740 disposed outside the unwinding drum 400 and fixed to the outer ends of the multiple guide rods 720. The vertical pull rod 740 allows the operator to easily pull the arc-shaped plates 710 of the two clamping mechanisms 700 from outside the unwinding drum 400, causing the two arc-shaped plates 710 to move outward, thereby providing sufficient space for inserting or replacing the wound glass fiber bundle.

[0053] The above are merely specific embodiments of this utility model and do not limit the patent scope of this utility model. Although embodiments of this utility model have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the claims and their equivalents. Those skilled in the art can make various other corresponding changes and modifications based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model.
