[0103] Embodiment 1
[0104] The fixture for assisting in taping a wire in this embodiment is as Figure 1-2 shown. The fixture includes a first clamping portion 1 and a second clamping portion 2. The first clamping portion 1 and the second clamping portion 2 are integrally connected by a pivot structure. The first clamping portion 1 and the second clamping portion 2 can rotate around the pivot structure to open and close. When the first clamping portion 1 and the second clamping portion 2 are closed, a first inner contour 4 of the first clamping portion 1 and a second inner contour 5 of the second clamping portion 2 form a groove, which is used to make the tape adhere to the wire for winding when the tape wraps around the wire. The pivot structure includes a spring (not shown), and the spring provides a restoring force that tends to keep the first clamping portion 1 and the second clamping portion 2 in a closed state. The spring is sleeved on a pivot 3 of the pivot structure. A first end of the spring is fixedly connected to the first clamping portion 1, and a second end of the spring is fixedly connected to the second clamping portion 2. The inner surface of the fixture is treated to prevent adhesion. For example, the inner surface of the fixture is coated with an anti-adhesive coating (such as Teflon).
[0105] The first inner contour 4 is a single-curvature arc, and its radius is 10 - 15 times the radius of the wire. The second inner contour 5 includes a first curvature arc and a second straight line. The first curvature arc is arranged close to the pivot point, and the second straight line is arranged outside the first curvature arc. The radius of the first curvature arc is 1.1 - 2 times the radius of the wire. The second straight line is a tangent extending outward from the first curvature arc.
[0106] In another embodiment, the second straight line can be replaced by a second curvature arc, and the radius of the second curvature arc is 5 - 20 times the radius of the wire.
[0107] The first clamping portion 1 includes a first pivot hole 6, and the second clamping portion 2 includes a second pivot hole 7. The first pivot hole 6 is arranged on the first connecting side of the first clamping portion 1, and the second pivot hole 7 is arranged on the second connecting side of the second clamping portion 2. Among them, the first pivot hole 6 and the second pivot hole 7 are used to accommodate the pivot 3 of the pivot structure.
[0108] The first clamping portion 1 includes a first handle 8 extending outward from the first connection side of the first clamping portion 1. The second clamping portion 2 includes a second handle 9 extending outward from the second connection side of the second clamping portion 2. The opening and closing angle of the first clamping portion 1 relative to the second clamping portion 2 is controlled by controlling the first handle 8 and the second handle 9. The angle formed by the first handle 8 and the first clamping portion 1 is between 120° and 170°; the angle formed by the second handle 9 and the second clamping portion 2 is between 90° and 150°.
[0109] The tape includes a first adhesive section, a second adhesive section, and optionally a third adhesive section. The first adhesive section and the second adhesive section are respectively arranged at both ends of the inner surface of the tape. In use, the first adhesive section is first attached to the outer periphery of the wire. After the tape is wrapped around the wire by the fixture, the second adhesive section adheres to the outer surface of the tape to complete the wrapping. The third adhesive section is arranged on the outer surface of the tape and is used to bond with the second adhesive section at the end of the wrapping, so as to reinforce the stability of the wrapping.
[0110] The wire can be a single wire in segments or a combination of multiple wires (such as a bundled structure of multiple wires, etc.). The diameter of the wire to be wrapped is 3 - 30 mm; preferably, 9 - 25 mm; more preferably, 15 - 20 mm. The length of the wire is 5 - 40 cm; preferably, 10 - 30 cm; more preferably, 15 - 25 cm.
[0111] The length of the fixture is 10 - 50 cm; preferably, 15 - 40 cm; more preferably, 20 - 30 cm. Preferably, the fixtures can be combined into a whole in the length direction to be applicable to wires with longer lengths.
[0112] Preferably, the length is configured such that the length of the fixture is greater than the length of the tape and less than the length of the wire.
[0113] Embodiment 2
[0114] The tape - wrapped wire system of this embodiment is as Figure 3 shown. The system includes a feeding device (not shown), a preliminary attachment device (not shown), a fixture and a mechanical clamp for assisting in wrapping the wire 11 with the tape.
[0115] The feeding device includes a tape feeding device and a wire feeding device. The tape feeding device is used to provide a segmented tape, and the wire feeding device is used to provide a segmented wire 11.
[0116] The mechanical clamp 10 is used to clamp both ends of the wire 11 respectively, and can drive the wire 11 to rotate by the rotation of the motor shaft of the motor 12. The mechanical clamp 10 includes a horizontal slide rail 13 and a vertical lifting bracket 14. The mechanical clamp 10 realizes movement in the horizontal plane through the horizontal slide rail 13 and realizes movement in the vertical plane through the vertical lifting bracket 14. Thus, the free movement of the mechanical clamp 10 in the three-dimensional space can be realized. In another preferred example, the movement of the mechanical clamp 10 is not realized in the above manner but directly controlled by a robotic arm to move in space. The operations of wire feeding, preliminary attachment, and tape wrapping all require the operation of the mechanical clamp 10.
[0117] The preliminary attachment device is used to attach the first adhesive section of the tape to the outer periphery of the wire 11. The operating surface of the preliminary attachment device is anti-stick treated, which is particularly applicable when there are adhesive parts on both sides (inner surface and outer surface) of the tape (for example, in the tape in Embodiment 1, in addition to the first adhesive section and the second adhesive section, there is also a third adhesive section), to avoid unwanted adhesion, such as avoiding the tape sticking to the operating table, etc.
[0118] The preliminary attachment device is configured to turn the inner surface of the tape upward, and the wire 11 falls from top to bottom onto the first adhesive section, so as to attach the first adhesive section of the tape to the outer periphery of the wire 11. Preferably, after the wire 11 falls from top to bottom onto the first adhesive section, the mechanical clamp 10 further presses down the wire 11. More preferably, after further pressing down the wire 11, the mechanical clamp 10 pre-rotates 5 - 15 degrees. These are all to strengthen the firmness of the preliminary attachment.
[0119] In another embodiment, the preliminary attachment device is configured to set an arc-shaped groove on the operating platform, where the arc-shaped groove and the wire 11 are adapted, that is, the arc-shaped groove can exactly accommodate the wire 11. Place one end of the tape with the first adhesive section and the inner surface upward above the arc-shaped groove, and control the mechanical clamp 10 to drop the wire 11 from top to bottom onto the first adhesive section and further press down until the wire 11 tightly presses the bottom of the arc-shaped groove, so as to attach the first adhesive section of the tape to the outer periphery of the wire 11.
[0120] In another embodiment, the preliminary attachment device is configured to place the tape with the inner surface upward on a pneumatic plane. By controlling the mechanical clamp 10 to drop the wire 11 from top to bottom onto the first adhesive section of the tape, the pneumatic plane inflates and expands to tightly attach the tape, especially the tape part with the first adhesive section, to the wire 11, so as to attach the first adhesive section of the tape to the outer periphery of the wire 11. The pneumatic plane deflates to complete the preliminary attachment work.
[0121] The fixture for assisting in taping a wire in this embodiment includes a first clamping portion 1 and a second clamping portion 2. The first clamping portion 1 includes a first inner contour 4, and the first inner contour 4 is a single-curvature arc with a radius 10 - 15 times that of the wire 11. The second clamping portion 2 includes a second inner contour 5; the second inner contour 5 is a single-curvature arc with a radius 1.5 - 10 times that of the wire 11. The second clamping portion 2 is fixed on the operating tabletop, and the first clamping portion 1 can rotate around one of its sides under the drive of a driving device to realize the opening and closing of the first clamping portion 1 relative to the second clamping portion 2. When the first clamping portion 1 and the second clamping portion 2 are closed, the first inner contour 4 and the second inner contour 5 form a groove, and the groove is used to make the tape adhere to the wire 11 for wrapping when the tape surrounds the wire 11.
[0122] During operation, the mechanical clamp 10 moves the wire 11 with the tape preliminarily attached thereto into the second inner contour 5 of the second clamping portion 2 where the first clamping portion 1 and the second clamping portion 2 are in an open state. The first clamping portion 1 rotates and presses down unilaterally to form a groove with the second clamping portion 2. The groove provides a force for the tape to adhere to the wire 11 for wrapping, and the mechanical clamp 10 drives the wire 11 to rotate so that the tape wraps around the wire 11.
[0123] In another embodiment, the fixture is configured like a coiled metal sheet. In the preliminary attachment stage, the metal sheet is in an extended state. After the preliminary attachment is completed, the metal sheet is released into a coiled state to semi-wrap the wire, and the mechanical clamp is controlled to rotate the wire so that the tape wraps around the wire.
[0124] Embodiment 3
[0125] The tape-wrapping wire system of this embodiment is similar to that of Embodiment 2. The difference is that in this embodiment, the wire is placed on a (hollow) support frame, and it is fed through the support frame and remains on the support frame subsequently. The preliminary attachment device is configured to set an arc-shaped groove on the lower operating platform, where the arc-shaped groove is adapted to the wire, that is, the arc-shaped groove can exactly accommodate the wire, and part of the wire is exposed outside the arc-shaped groove. By first moving up the lower operating platform to accommodate the wire in its arc-shaped groove, the tape is clamped or adsorbed on the upper operating platform with its inner surface facing down. By pressing down the upper operating platform, or by the magnetic force that the upper operating platform and the lower operating platform can generate mutual attraction to fit when energized, the upper operating platform and the lower operating platform are closed, so that the first bonding section of the tape is attached to the outer periphery of the wire. Preferably, the upper operating platform is provided with an arc-shaped groove corresponding to the arc-shaped groove, and the first bonding section of the tape is arranged corresponding to this arc-shaped groove.
[0126] The mechanical clamp includes an opening / closing mechanical control part and a circumferential rotation control part. The opening / closing mechanical control part is used to control the opening and closing of the first clamping part and the second clamping part. The opening / closing mechanical control part is arranged on the circumferential rotation control part, and the circumferential rotation control part is used to control the rotation of the opening / closing mechanical control part together with the fixture. The opening / closing mechanical control part includes a first opening / closing mechanical control part and a second opening / closing mechanical control part. The first opening / closing mechanical control part is connected to the first clamping part, and the second opening / closing mechanical control part is connected to the second clamping part. The circumferential rotation control part includes an arc-shaped slide rail and a sliding part that can slide along the arc-shaped slide rail; the sliding part is detachably / adsorptively connected to the fixture or the opening / closing mechanical control part, and the rotation of the fixture is driven by the circumferential movement of the sliding part along the arc-shaped slide rail.
[0127] When the tape (for example, the first bonding section of the tape) is preliminarily attached to the outer periphery of the wire, local auxiliary heating with a temperature of 30-50 °C is provided to the tape for 3-10 s, so that the tape is more firmly attached to the outer periphery of the wire.
