Description

Technical Field

[0001] This utility model relates to the field of motor production and assembly equipment, specifically a tape reel oscillation device and a tape wrapping head. Background Technology

[0002] In motor manufacturing and assembly, automatic tape wrapping machines are used to wrap the coils with insulating tape. During the wrapping process, the wrapping head of the automatic tape wrapping machine drives a pair of tape reels to rotate around the coil, evenly overlapping the insulating tape onto the coil surface. To ensure a certain overlap rate of the insulating tape during wrapping and to prevent folding of the insulating tape, the tape reels need to be tilted within a certain range while rotating around the coil, allowing the insulating tape to be tilted and overlapped onto the coil surface. In existing technology, the tape reel tilting is achieved by a motor driving a reducer and gear transmission. Although this allows for precise control of the tape reel tilting angle, the excessive number of intermediate transmission components, and the increased clearance of worn gears and other transmission components, affect the accuracy of the tape reel tilting and are detrimental to the control of the overlap rate.

[0003] A search revealed existing technical documents concerning tape reel deflection or tape wrapping heads. Examples include the utility model patent announcement document with publication number "CN204046374U" entitled "A Tape Wrapping Head," and the utility model patent announcement document with publication number "CN211078009U" entitled "A CNC Tape Wrapping Head for Coil Insulation Tape." All the aforementioned tape reel deflection adjustment schemes in these existing technical documents suffer from the aforementioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a disc-driven oscillation device, including a rotating shaft capable of driving the disc to oscillate, a transmission arm connected to the rotating shaft, and a telescopic drive unit. The telescopic drive unit has a movable end and a fixed end, with the movable end hinged to one end of the transmission arm. The extension and retraction of the movable end of the telescopic drive unit can drive the transmission arm to oscillate, thereby driving the rotating shaft to rotate.

[0005] Furthermore, the fixed end of the telescopic drive unit is hinged to an external fixed component, and the length of the transmission arm is determined.

[0006] Furthermore, it also includes a mounting base, one end of which is connected to a hinged base. The hinged base and the fixed end of the telescopic drive unit are hinged together. One end of the base relative to the hinged base is a bearing seat. The rotating shaft is connected through the bearing seat. One end of the rotating shaft is connected to the transmission arm, and the other end is connected to the oscillation seat.

[0007] Furthermore, the hinge seat and the base are connected by a guide rail slide pair.

[0008] Furthermore, one side of the bearing seat has a scale, and the oscillating seat has a pointer or scale indicator groove.

[0009] Alternatively, the transmission arm is telescopic, with its telescopic end hinged to the movable end of the telescopic drive unit, and the fixed end of the telescopic drive unit fixedly connected to an external fixed component.

[0010] A strapping head is also proposed, characterized in that it includes the above-mentioned tape reel tilting device, and a tape reel seat is connected to the strapping head rotating body, with one end of the tape reel seat connected to the rotating shaft and the other end hinged to the strapping head rotating body.

[0011] Furthermore, the inner ring of the tape head rotating body is connected to the opposite first support plate and second support plate. The first support plate carries the tape reel deflection device, and the second support plate is hinged to one end of the tape reel seat.

[0012] Furthermore, the rotating shaft is also connected to a pair of zero plates, which have a through groove in the center and a photoelectric sensor is also provided on the first support plate.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects: The belt reel deflection device proposed in this utility model uses a telescopic drive unit and a transmission arm that are hinged to each other to drive the rotating shaft to rotate, thereby driving the belt reel to deflect. Since there are no excessive intermediate transmission components, the deflection control accuracy is higher, and the deflection angle control accuracy will not decrease due to the wear of transmission components. The wrapping head using this belt reel deflection device also has better stacking rate control accuracy. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] A disc-shaped oscillating device includes a rotating shaft 11 capable of driving the disc 1 to oscillate, a transmission arm 12 connected to the rotating shaft 11, and a telescopic drive unit 13, the telescopic drive unit 13 having a movable end and a fixed end, the movable end being hinged to one end of the transmission arm 12.

[0022] The above constitutes the basic structural design of the belt reel swaying device. When the movable end of the telescopic drive unit 13 extends or retracts, since the transmission arm 12 is hinged to the movable end, it can drive the transmission arm 12 to oscillate back and forth within a certain angle range, thereby driving the rotating shaft 11 to rotate. It can be understood that when the rotating shaft 11 rotates, if it is connected to the belt reel 1, it can drive the belt reel 1 to sway within a certain angle range. Unlike existing technologies, this structural design does not require excessive intermediate transmission components, improving the control accuracy of the belt reel swaying. Since there are no gears, belts, or other transmission components, the control accuracy of the belt reel swaying will not be reduced due to wear. Obviously, when the length of the transmission arm 12 and the stroke of the telescopic drive unit 13 are known, the belt reel swaying effect can be precisely controlled by controlling the extension and retraction stroke of the movable end of the telescopic drive unit 13, combined with certain feedback control. The specific implementation methods will be described below using different embodiments.

[0023] Example 1: See Figure 1 , Figure 3 and Figure 4 .

[0024] The fixed end of the telescopic drive unit 13 is hinged to an external fixed component, and the length of the transmission arm 12 is fixed. In this embodiment, both ends of the telescopic drive unit 13 are hinged, and the length of the transmission arm 12 during swaying is fixed. It should be noted that the length of the transmission arm 12 is fixed after the sway angle control range of the pulley is determined, but this does not mean that its length is fixed. It can be designed to be adjustable in length. When adjusted to a fixed length, under the premise that the stroke of the movable end of the telescopic drive unit 13 is fixed, the sway angle range of the pulley 1 is fixed. The structural principle is as follows: Figure 1 As shown, when the movable end of the telescopic drive unit 13 extends or retracts, the telescopic drive unit 13 itself will rotate around its fixed end hinge point, and the transmission arm 12 will rotate around the axis of the rotating shaft 11 under the drive of the movable end, thereby driving the pulley 1 to sway.

[0025] For a more preferred embodiment, see [reference needed]. Figure 3 and Figure 4 It also includes a mounting base 14, one end of which is connected to a hinge base 15. The hinge base 15 is hinged to the fixed end of the telescopic drive unit 13. The end of the mounting base 14 opposite to the hinge base 15 is a bearing seat 16. The telescopic drive unit 13 can be an electric cylinder. The rotating shaft 11 extends through the bearing seat 16 and out at both ends. One end is connected to a swing arm 17, and the other end is connected to a transmission arm 12. The swing arm 17 has connecting ears at both ends, which can be used to fix external components. The transmission arm 12 is fixedly connected to one end of the rotating shaft 11 by bolts, which facilitates assembly and disassembly.

[0026] In a more preferred embodiment, the hinge seat 15 and the mounting seat 14 are connected by a guide rail slide pair 18. This allows adjustment of the position of the fixed end of the electric cylinder, thereby adjusting the stroke range of its movable end.

[0027] In a more preferred embodiment, one side of the bearing seat 16 has a scale, and the yaw seat 17 has a pointer or scale indicator groove. Specifically, one side of the yaw seat 17 is an arc surface concentric with the swing path of the transmission arm 12. When the yaw seat 17 is driven to yaw, the angle of deflection can be indicated by the pointer or scale indicator groove.

[0028] Example 2: See Figure 2 .

[0029] The difference between this embodiment and Embodiment 1 lies in the connection method between the transmission arm 12 and the telescopic drive unit 13. Other specific structural components can be found in Embodiment 1. In this embodiment, the fixed end of the telescopic drive unit 13 is non-rotatable and can be fixed to an external component as needed. The transmission arm 12 is telescopic; when the movable end of the telescopic drive unit 13 extends or retracts, the transmission arm 12 can rotate around its hinge point with the movable end of the telescopic drive unit 13, while simultaneously extending and retracting itself, thereby driving the rotating shaft 11 to rotate.

[0030] Example 3: Based on the above examples, a bag strap head is also proposed, see details below. Figure 5 and Figure 6 .

[0031] A tape wrapping head includes the tape reel tilting device described in the foregoing embodiments. A tape reel seat 2 is connected to the tape wrapping head rotating body 3. One end of the tape reel seat 2 is connected to a rotating shaft 11, and the other end is hinged to the tape wrapping head rotating body 3. When the telescopic drive unit 13 drives the rotating shaft 11 to rotate, the tilting angle of the tape reel seat 2 can be precisely controlled, thereby controlling the tilting of the tape reel 1 connected to the tape reel seat 2. When the tilting accuracy of the tape reel 1 can be precisely controlled and will not be reduced due to wear of transmission components, the stacking rate control accuracy of this tape wrapping head during tape wrapping operations will be greatly improved and made more reliable.

[0032] In a more preferred embodiment, the inner ring of the tape head rotator 3 is connected to a first support plate 31 and a second support plate 31, with the first support plate 31 supporting the tape reel swaying device and the second support plate 32 hinged to one end of the tape reel seat 2. Specifically, the swaying devices are arranged in pairs. The mounting base 14 and the bearing seat 16 are fixedly supported on the first support plate 31, while the swaying seat 17 is suspended but connected to one end of the tape reel seat 2, and the second support plate 32 is hinged to the other end of the tape reel seat 2 via a shaft. Therefore, when the swaying device drives the swaying seat 17 to swing, the tape reel seat 2 will cause the tape reel 1 to sway between the first support plate 31 and the second support plate 31.

[0033] In a more preferred embodiment, to correct the horizontal zero position of the reel's sway, a pair of zero-position plates 33 are also connected to the rotating shaft 11. Each pair of zero-position plates 33 has a central slot, and a photoelectric sensor 34 is mounted on the first support plate 31. Specifically, the pair of zero-position plates 33 are fixedly connected to one side of the sway seat 17 via a connecting lug. When the reel is at the horizontal zero position, the central slot of the pair of zero-position plates 33 aligns with the transmission and reception path of the photoelectric sensor 34, at which point the photoelectric sensor 34 generates a valid zero-position signal. When the reel sways by a certain angle, the pair of zero-position plates 33 blocks the transmission and reception of the photoelectric sensor 34, at which point the zero-position signal becomes invalid.
