Description

Technical Field

[0001] This utility model relates to the field of prepreg winding technology, specifically to a correction mechanism for high-tension winding. Background Technology

[0002] During the prepreg winding process, the correction mechanism is a device or system used to monitor and correct the lateral positional deviation of the prepreg on the winding path in real time; its core objective is to ensure that the prepreg is laid accurately along the preset trajectory and avoid product performance degradation caused by deviation.

[0003] In the prior art, the correction mechanism for prepreg winding mostly adopts mechanical limiting constraints, such as guide grooves and adjustable baffles, to restrict the lateral degree of freedom of the prepreg through rigid boundaries. However, the friction between the prepreg and the limiting mechanism can cause fiber breakage and resin interface peeling, resulting in burrs on the edge of the prepreg and reducing the interlayer bonding strength, thus limiting its application in precision motor rotor winding.

[0004] When the prepreg tape deviates from the centerline, the contact parts of the fixed device (such as guide grooves) generate a reverse force through extrusion or rolling friction, forcing the prepreg tape back to the set track. The existing technology has the following drawbacks:

[0005] 1. It cannot automatically adapt to different offsets and requires manual adjustment of the device position after stopping the machine;

[0006] 2. Friction between the prepreg tape and the limiting mechanism can cause burrs on the prepreg tape, affecting the fiber winding effect;

[0007] 3. The correction accuracy is low, making it difficult to meet high-precision requirements. Utility Model Content

[0008] The present invention aims to solve the above-mentioned technical problems by providing a correction mechanism for high-tension winding. This correction mechanism detects the deviation of the prepreg tape through a photoelectric sensor and compensates for it by moving the adjusting seat through a telescopic electric cylinder, thereby achieving high-precision dynamic correction.

[0009] To solve the above-mentioned technical problems, the present invention provides a technical solution for a correction mechanism for high-tension winding:

[0010] The device includes two side plates and a photoelectric sensor. Two guide shafts connect the two side plates. An adjusting seat is slidably connected to the two guide shafts. A telescopic cylinder is mounted on the front of the upper end of the adjusting seat. A fixed seat is mounted on the telescopic end of the telescopic cylinder. A pressure roller is rotatably connected below the fixed seat. A roller located below the pressure roller is also connected to the front of the adjusting seat. The photoelectric sensor is located behind the adjusting seat. One of the two side plates has a mounting plate connected to its side. An electric cylinder fixing seat is connected to the front of the mounting plate. A telescopic electric cylinder is mounted on the electric cylinder fixing seat. The telescopic end of the telescopic electric cylinder is connected to the adjusting seat.

[0011] The roller is rotatably connected to the guide shaft located above.

[0012] A first linear bearing is slidably connected to the guide shaft located above; a first spacer is connected to the outside of the first linear bearing; a first cover is connected to the side of the first spacer; the first cover and the first spacer are both connected to the adjusting seat by bolts; the roller is mounted on the first spacer.

[0013] A rotating shaft is connected below the fixed base; deep groove ball bearings are connected to both sides of the rotating shaft; the pressure roller is mounted on the two deep groove ball bearings.

[0014] A second spacer is placed between the deep groove ball bearing and the fixed seat.

[0015] Of the two guide shafts, a second linear bearing is slidably connected to the lower guide shaft; a third spacer is connected to the outside of the second linear bearing; a second cover is connected to the side of the third spacer; the second cover and the third spacer are both connected to the adjusting seat by bolts.

[0016] The side plate and the mounting plate are connected by reinforcing ribs.

[0017] The technical effects that this utility model can achieve are:

[0018] 1. This utility model is mainly composed of components such as a telescopic electric cylinder, a photoelectric sensor, and a pressure roller. After the photoelectric sensor detects that the prepreg tape has shifted, it can drive the telescopic electric cylinder to drive the adjusting seat and the prepreg tape located on the adjusting seat to perform lateral displacement compensation, thereby achieving high-precision dynamic correction.

[0019] 2. After the prepreg tape passes through the roller, the continuous pressure applied by the telescopic cylinder causes the pressure roller to press down to ensure that the prepreg tape fits the saddle-shaped roller surface of the roller, ensuring that the prepreg tape will not have a large deviation.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] See Figures 1 to 6 .

[0029] A correction mechanism for high-tension winding includes two side plates 4 and a photoelectric sensor 23. Two guide shafts 5 are connected between the two side plates 4. An adjusting seat 25 is slidably connected to the two guide shafts 5. A telescopic cylinder 14 is installed on the front side of the upper end of the adjusting seat 25. A fixed seat 13 is installed on the telescopic end of the telescopic cylinder 14. A pressure roller 19 is rotatably connected below the fixed seat 13. Specifically, in the installation of the pressure roller 19, a rotating shaft 18 is connected below the fixed seat 13. Deep groove ball bearings 21 are connected to both sides of the rotating shaft 18. The pressure roller 19 is installed on the two deep groove ball bearings 21. A second spacer 20 is placed between the deep groove ball bearings 21 and the fixed seat 13.

[0030] The front side of the adjusting seat 25 is also connected to a roller 15 located below the pressure roller 19. Specifically, the roller 15 is rotatably connected to the guide shaft 5 located above. More specifically, a first linear bearing 22 is slidably connected to the guide shaft 5 located above. A first spacer 8 is connected to the outside of the first linear bearing 22. A first cover 10 is connected to the side of the first spacer 8. The first cover 10 and the first spacer 8 are both connected to the adjusting seat 25 by bolts. The roller 15 is installed on the first spacer 8. This utility model uses a telescopic cylinder 14 to push the fixed seat 13 and the pressure roller 19 down, thereby ensuring that the prepreg tape adheres to the saddle-shaped roller surface of the roller 15.

[0031] The photoelectric sensor 23 is located behind the adjusting seat 25; one of the two side plates 4 is connected to the side of the mounting plate 2; preferably, a reinforcing rib 33 is connected between the side plate 4 and the mounting plate 2 to increase the connection strength between the side plate 4 and the mounting plate 2; the front side of the mounting plate 2 is connected to the electric cylinder fixing seat 1, and the electric cylinder fixing seat 1 is equipped with a telescopic electric cylinder 3, the telescopic end of the telescopic electric cylinder 3 is connected to the adjusting seat 25; on the guide shaft 5 located below, a second linear bearing 31 is slidably connected to the guide shaft 5 located below, a third spacer 9 is connected to the outside of the second linear bearing 31, a second cover 32 is connected to the side of the third spacer 9, and the second cover 32 and the third spacer 9 are both connected to the adjusting seat 25 by bolts.

[0032] After the prepreg tape passes through the roller 15, the continuous pressure applied by the telescopic cylinder 14 ensures that the prepreg tape adheres to the saddle-shaped roller surface of the roller 15. The advantage of the saddle-shaped roller surface is that when the prepreg tape deviates, the lateral friction force generated guides the prepreg tape back to the center. When the photoelectric sensor 23 detects that the prepreg tape has deviated, the telescopic cylinder 3 drives the adjusting seat 25 and the prepreg tape located on the adjusting seat 25 to perform lateral displacement compensation, thereby achieving high-precision dynamic correction.
