FIGS. 8-1 to 8-5 are (a) a top view and (b) a front view showing first to fifth states of a partial configuration of a tape winding device according to an embodiment of the present invention, respectively. FIGS. 9-1 to 9-2 are (a) a top view, (b) a front view and (c) a right side view showing first to second states of a tape holding unit of a tape winding device according to an embodiment of the present invention, respectively. The front, back, left side, right side, and top of the tape winding device refer to the sides located in the forward, rear, left, right, and top directions, respectively, as indicated by arrows in Fig. 1. Below, the configuration of the tape winding device 1 in the embodiment of the present invention will be described using these figures as appropriate.

[0027] As shown in Fig. 8-1(a), the workpiece on which the adhesive tape is wound by the tape winding device 1 is made up of a first workpiece W1 and a second workpiece W2. The first workpiece W1 is made up of a substantially cylindrical electronic component body W1a, an electric wire (cable) W1b connected to one end thereof, and a connector W1c. The second workpiece W2 is made up of a cylindrical resin tube called a corrugated tube. The second workpiece W2 is attached in advance to the outer peripheral surface of the electric wire W1b of the first workpiece W1.

[0028] As shown in Figures 1 to 3, the tape winding device 1 includes a first work holding unit 10 (10a, 10b), a second work positioning unit 20, a second work holding unit 30, a tape winding unit 40, a tape holding unit 50, a tape pressing unit 60, and a base unit 70.

[0029] <Configuration of first workpiece holding unit 10> The first work holding unit 10 is composed of a first work holding unit 10a located on the left side of the tape winding device 1 and a first work holding unit 10b located on the right side of the tape winding device 1.

[0030] As shown in Figure 2, the first work holding unit 10a, located on the left side of the tape winding device 1, is equipped with a first work left side support block 11 that supports the electronic component body W1a of the first work W1 from below, a first work left side pressing plate 12 that presses the electronic component body W1a of the first work W1 from above, a left-right slide drive unit 13 that moves the first work left side support block 11 in the left-right direction, and a front-to-rear slide drive unit 14 that moves the first work left side pressing plate 12 in the front-to-rear direction.

[0031] As shown in FIG. 8-1(b), the first work left support block 11 is fixed to the movable part 131 of the horizontal slide drive unit 13, and is further fixed to the movable part 711 of the horizontal slide drive unit 71 of the base unit 70 via the horizontal slide drive unit 13. The first work left support block 11 has a recess with which the electronic component body W1a of the first work W1 engages. When the electronic component body W1a of the first work W1 engages with this recess, the electronic component body W1a of the first work W1 is positioned relative to the first work left support block 11. The first work left support block 11 can move in the horizontal direction together with the movable part 131 of the horizontal slide drive unit 13. When the movable part 131 of the horizontal slide drive unit 13 moves slightly to the left, the electronic component body W1a of the first work W1 supported by the first work left support block 11 also moves slightly to the left, and the tension acting on the electric wire W1b of the first work W1 increases by that amount. Conversely, when the movable part 131 of the horizontal slide drive part 13 moves slightly to the right, the electronic component body W1a of the first work W1 supported by the first-work left support block 11 also moves slightly to the right, and the tension acting on the electric wire W1b of the first work W1 decreases accordingly. In this way, the horizontal slide drive part 13 can adjust the tension acting on the electric wire W1b of the first work W1.

[0032] As shown in FIG. 8-1(b), the first work left side pressing plate 12 is fixed to the movable part 141 of the front-rear slide drive part 14. The first work left side pressing plate 12 can move in the front-rear direction together with the movable part 141 of the front-rear slide drive part 14. This allows the first work left side pressing plate 12 to take a first state shown in FIG. 8-1 and a second state shown in FIG. 8-2. In the first state shown in FIG. 8-1, the first work left side pressing plate 12 stops at a position a certain distance forward from the electronic component body W1a of the first work W1. When the state of the first work left side pressing plate 12 shifts from the first state shown in FIG. 8-1 to the second state shown in FIG. 8-2, the first work left side pressing plate 12 moves a certain distance backward and abuts against the upper surface of the electronic component body W1a of the first work W1 while sliding. As a result, the electronic component body W1a of the first work W1 is clamped between the upper surface of the first work left side support block 11 and the lower surface of the first work left side pressing plate 12.

[0033] 8-1(b), the left / right slide drive unit 13 and the front / rear slide drive unit 14 are fixed to a movable part 711 of the left / right slide drive unit 71 of the base unit 70. The left / right slide drive unit 13 and the front / rear slide drive unit 14 are formed of a power source such as a motor or an arbitrary drive mechanism, and are configured to linearly move the movable part 131 in the left / right direction and to linearly move the movable part 141 in the front / rear direction, respectively.

[0034] As shown in Figure 2, the first work holding unit 10b, located on the right side of the tape winding device 1, is equipped with a first work right side support block 15 that supports the right end portion (connector W1c) of the first work W1 from below, a first work right side pressing plate 16 that presses the right end portion of the first work W1 from above, and a front-to-rear slide drive unit 17 that moves the first work right side pressing plate 16 in the front-to-rear direction.

[0035] The first-work right-side support block 15 is fixed to the movable part 711 of the left-right slide drive part 71 of the base unit 70. The first-work right-side support block 15 has a recess with which the right end part of the first work W1 engages. When the right end part of the first work W1 engages with this recess, the right end part of the first work W1 is positioned at a predetermined position with respect to the first-work right-side support block 15.

[0036] As shown in FIG. 8-1(b), the first workpiece right side pressing plate 16 is fixed to the movable part 171 of the front-rear slide drive part 17. The first workpiece right side pressing plate 16 can move in the front-rear direction together with the movable part 171 of the front-rear slide drive part 17. As a result, the first workpiece right side pressing plate 16 can take a first state shown in FIG. 8-1 and a second state shown in FIG. 8-2. In the first state shown in FIG. 8-1, the first workpiece right side pressing plate 16 stops at a position a certain distance forward from the connector W1c of the first workpiece W1. When the state of the first workpiece right side pressing plate 16 shifts from the first state shown in FIG. 8-1 to the second state shown in FIG. 8-2, the first workpiece right side pressing plate 16 moves a certain distance backward and abuts against the upper surface of the connector W1c of the first workpiece W1 while sliding. As a result, the connector W1c of the first workpiece W1 is sandwiched between the upper surface of the first workpiece right support block 15 and the lower surface of the first workpiece right side pressing plate 16.

[0037] 8-1(b), the front-rear slide drive unit 17 is fixed to a movable part 711 of the left-right slide drive unit 71 of the base unit 70. The front-rear slide drive unit 17 is composed of a power source such as a motor or an arbitrary drive mechanism, and is configured to linearly move the movable part 171 in the front-rear direction.

[0038] <Configuration of second workpiece positioning unit 20> As shown in Figure 2, the second work positioning unit 20 includes a second work positioning plate 21 that positions the second work W2, a front-to-rear slide drive unit 22 that moves the second work positioning plate 21 in the front-to-rear direction, and a left-to-right slide drive unit 23 that moves the second work positioning plate 21 in the left-to-right direction.

[0039] As shown in FIG. 8-1(b), the second work positioning plate 21 is fixed to the movable part 221 of the front-rear slide drive unit 22, and is further fixed to the movable part 231 of the left-right slide drive unit 23 via the front-rear slide drive unit 22. As shown in FIG. 2, the second work positioning plate 21 has a V-shaped slit opening 211 at its tip into which the electric wire W1b of the first work W1 is inserted. The second work positioning plate 21 can move in the front-rear direction together with the movable part 221 of the front-rear slide drive unit 22, and can also move in the left-right direction together with the movable part 231 of the left-right slide drive unit 23. As a result, the second work positioning plate 21 can take a first state shown in FIG. 8-1, a second state shown in FIG. 8-2, and a third state shown in FIG. 8-3. In the first state shown in FIG. 8-1, the second work positioning plate 21 is stopped at a position a certain distance forward from the electric wire W1b of the first work W1. When the state of the second work positioning plate 21 transitions from the first state shown in Fig. 8-1 to the second state shown in Fig. 8-2, the second work positioning plate 21 moves a certain distance backward, the electric wire W1b of the first work W1 is inserted into the slit opening 211 at the tip, and the second work positioning plate 21 stops at a position facing the right side surface of the second work W2 with a certain gap in the left direction. When the state of the second work positioning plate 21 transitions from the second state shown in Fig. 8-2 to the third state shown in Fig. 8-3, the second work positioning plate 21 moves a certain distance leftward and abuts on the right side surface of the second work W2. As a result, the second work W2 is pressed against the right side surface of the electronic component body W1a of the first work W1 and is positioned with respect to the first work W1.

[0040] 8-1(b), the front-rear slide drive unit 22 is fixed to a movable part 231 of the left-right slide drive unit 23. The left-right slide drive unit 23 is fixed to a movable part 711 of the left-right slide drive unit 71 of the base unit 70. The front-rear slide drive unit 22 and the left-right slide drive unit 23 are constituted by a power source such as a motor or an arbitrary drive mechanism, and are respectively configured to linearly move the movable part 221 in the front-rear direction and to linearly move the movable part 231 in the left-right direction.

[0041] <Configuration of second workpiece holding unit 30> As shown in Figure 2, the second work holding unit 30 includes a second work holding hand 31 that grasps the second work W2, a front-to-rear slide drive unit 32 that moves the second work holding hand 31 in the front-to-rear direction, and a left-to-right slide drive unit 33 that moves the second work holding hand 31 in the left-to-right direction.

[0042] As shown in FIG. 8-1(b), the second work holding hand 31 is fixed to the movable part 321 of the front-rear slide drive unit 32, and is further fixed to the movable part 331 of the left-right slide drive unit 33 via the front-rear slide drive unit 32. As shown in FIG. 2, the second work holding hand 31 has a pair of claws 311 of an opening / closing drive type at its tip, which grips the second work W2 from above and below. The second work holding hand 31 can move in the front-rear direction together with the movable part 321 of the front-rear slide drive unit 32, and can also move in the left-right direction together with the movable part 331 of the left-right slide drive unit 33. As a result, the second work holding hand 31 can take a first state shown in FIG. 8-1, a fourth state shown in FIG. 8-4, and a fifth state shown in FIG. 8-5. In the first state shown in FIG. 8-1, the second work holding hand 31 is stopped at a position a certain distance forward from the second work W2. When the state of the second work holding hand 31 transitions from the first state shown in Fig. 8-1 to the fourth state shown in Fig. 8-4, the second work holding hand 31 moves a fixed distance backward and grips the second work W2 from above and below with the pair of claws 311. When the state of the second work holding hand 31 transitions from the fourth state shown in Fig. 8-4 to the fifth state shown in Fig. 8-5, the second work holding hand 31 moves a fixed distance rightward while still gripping the second work W2 from above and below with the pair of claws 311. As a result, the second work W2 moves a fixed distance rightward along the outer circumferential surface of the electric wire W1b of the first work W1.

[0043] As shown in Fig. 8-1(b), the front-rear slide drive unit 32 is fixed to a movable part 331 of the left-right slide drive unit 33. The left-right slide drive unit 33 is fixed to a movable part 711 of the left-right slide drive unit 71 of the base unit 70. The front-rear slide drive unit 32 and the left-right slide drive unit 33 are formed of a power source such as a motor or an arbitrary drive mechanism, and are configured to linearly move the movable part 321 in the front-rear direction and the movable part 331 in the left-right direction, respectively.

[0044] <Configuration of the tape winding unit 40> As shown in FIG. 2, the tape winding unit 40 includes a tape reel 41 that stores the adhesive tape T, a tape guide roller 42 that guides the adhesive tape T pulled out from the tape reel 41, a rotating plate 43 that supports the tape reel 41 and the tape guide roller 42, and a rotation drive unit 44 that rotates the rotating plate 43.

[0045] The tape reel 41 is attached to the right side surface of the rotating plate 43, and can freely rotate clockwise and counterclockwise about a predetermined rotation axis extending in the left-right direction. When the adhesive tape T is pulled out from the tape reel 41, the tape reel 41 rotates freely in a predetermined direction and sequentially delivers the adhesive tape T toward the tape holding unit 50.

[0046] The tape guide roller 42 is attached to the right side surface of the rotating plate 43, and can freely rotate clockwise and counterclockwise around a predetermined rotation axis extending in the left-right direction. When the adhesive tape T is pulled out from the tape reel 41, the tape guide roller 42 passively rotates in a predetermined direction while in contact with the adhesive surface of the adhesive tape T, and guides the adhesive tape T toward the tape holding unit 50.

[0047] The rotating plate 43 is attached to the right side surface of the rotation drive unit 44 and is connected to a drive mechanism provided inside the rotation drive unit 44. The rotating plate 43 has a U-shaped slit opening 431 into which the first work W1 and the second work W2 are inserted. The rotating plate 43 can rotate clockwise and counterclockwise around a predetermined rotation axis that passes near the center of the slit opening 431 and extends in the left-right direction. When the first work W1 and the second work W2 are inserted near the center of the slit opening 431, the rotating plate 43 can rotate around the first work W1 and the second work W2. The tape reel 41 and the tape guide roller 42 attached to the rotating plate 43 can also rotate around the first work W1 and the second work W2 together with the rotating plate 43. As a result, the adhesive tape T pulled out from the tape reel 41 is wound around the outer circumferential surfaces of the first work W1 and the second work W2.

[0048] The rotation drive unit 44 is fixed to the base 73 of the base unit 70. As a result, the tape winding unit 40 is fixed to the base 73 of the base unit 70 as a whole. The rotation drive unit 44 has a U-shaped slit opening 441 similar to the U-shaped slit opening 431 provided in the rotating plate 43. When the first work W1 and the second work W2 are inserted into the slit opening 431 of the rotating plate 43, the first work W1 and the second work W2 are also inserted into the slit opening 441 of the rotation drive unit 44. The rotation drive unit 44 is configured with a power source such as a motor or an arbitrary drive mechanism, and is configured to rotate the rotating plate 43.

[0049] <Configuration of the tape holding unit 50> As shown in Figure 9-1, the tape holding unit 50 includes a tape pressure roller 51 that presses the upper surface (adhesive surface) of the adhesive tape T from above, a support pillar 52 that supports the tape pressure roller 51, a rotation drive unit 53 that rotates the support pillar 52 in the left-right direction, a tape support block 54 that supports the lower surface (non-adhesive surface) of the adhesive tape T from below, an up-down slide drive unit 55 that moves the tape support block 54 in the up-down direction, a tape cutter 56 that cuts the adhesive tape T, an up-down slide drive unit 57 that moves the tape cutter 56 in the up-down direction, and an up-down slide drive unit 58 that moves all of these components together in the up-down direction.

[0050] The tape pressure roller 51 has a curved surface that contacts the upper surface of the adhesive tape. The tape pressure roller 51 is attached to the side of the upper end of the support 52. The tape pressure roller 51 can freely rotate clockwise and counterclockwise around a predetermined rotation axis that extends horizontally from the support 52. The lower end of the support 52 is connected to a drive mechanism of the rotation drive unit 53. The support 52 can rotate clockwise and counterclockwise around a predetermined rotation axis that extends vertically by the power of the rotation drive unit 53. This allows the tape pressure roller 51 to take a first state shown in FIG. 9-1 and a second state shown in FIG. 9-2. In the first state shown in FIG. 9-1, the tape pressure roller 51 is stopped in a state where it extends backward from the support 52. 9-2, the tape pressure roller 51 rotates by 90° to the right as viewed from above, using the support pillar 52 as a fulcrum, and stops in a state where it extends to the right from the support pillar 52. As a result, the tape pressure roller 51 faces the upper surface of the adhesive tape T pulled out from the tape winding unit 40 and the upper surface of the tape support block 54.

[0051] The tape support block 54 has a flat upper surface that contacts the lower surface of the adhesive tape T. The tape support block 54 is fixed to the movable part 551 of the vertical slide drive part 55. The tape support block 54 can move up and down together with the movable part 551 of the vertical slide drive part 55. This allows the tape support block 54 to take a first state shown in FIG. 9-1 and a second state shown in FIG. 9-2. In the first state shown in FIG. 9-1, the tape support block 54 stops at a position a certain distance downward from the tape pressure roller 51. When the state of the tape support block 54 shifts from the first state shown in FIG. 9-1 to the second state shown in FIG. 9-2, the tape support block 54 moves a certain distance upward and contacts the lower surface of the tape pressure roller 51. As a result, the adhesive tape T pulled out from the tape winding unit 40 is sandwiched between the upper surface of the tape support block 54 and the lower surface of the tape pressure roller 51.

[0052] The tape cutter 56 has a triangular blade at its tip in the upward direction. The tape cutter 56 is fixed to the movable part 571 of the vertical slide drive part 57. The tape cutter 56 can move in the upward and downward direction together with the movable part 571 of the vertical slide drive part 57. This allows the tape cutter 56 to take a first state shown in FIG. 9-1 and a second state shown in FIG. 9-2. In the first state shown in FIG. 9-1, the tape cutter 56 is stopped at a position a certain distance downward from the tape pressure roller 51. When the state of the tape cutter 56 shifts from the first state shown in FIG. 9-1 to the second state shown in FIG. 9-2, the tape cutter 56 moves a certain distance upward and is positioned at the same height as the tape pressure roller 51. As a result, the adhesive tape T pulled out from the tape winding unit 40 is cut by the tape cutter 56.

[0053] The rotary drive unit 53 supporting the tape pressure roller 51 and the support column 52, the vertical slide drive unit 55 supporting the tape support block 54, and the vertical slide drive unit 57 supporting the tape cutter 56 are fixed to a movable part 581 of the vertical slide drive unit 58. This allows all of the components, namely the tape pressure roller 51, the support column 52, the rotary drive unit 53, the tape support block 54, the vertical slide drive unit 55, the tape cutter 56, and the vertical slide drive unit 57, to move integrally in the vertical direction together with the movable part 581 of the vertical slide drive unit 58. In the first state shown in FIG. 9-1, all of the components, namely the tape pressure roller 51, the support column 52, the rotary drive unit 53, the tape support block 54, the vertical slide drive unit 55, the tape cutter 56, and the vertical slide drive unit 57, move integrally in the downward direction together with the movable part 581 of the vertical slide drive unit 58. In the second state shown in Figure 9-2, all of the components, namely the tape pressure roller 51, the support pillar 52, the rotation drive unit 53, the tape support block 54, the vertical slide drive unit 55, the tape cutter 56, and the vertical slide drive unit 57, move upward together with the movable part 581 of the vertical slide drive unit 58.

[0054] The vertical slide drive section 58 is fixed to a pedestal 73 of the pedestal unit 70. As a result, the tape holding unit 50 as a whole is fixed to the pedestal 73 of the pedestal unit 70.

[0055] The rotation drive unit 53, the vertical slide drive unit 55, the vertical slide drive unit 57, and the vertical slide drive unit 58 are composed of a power source such as a motor or an arbitrary drive mechanism, and are respectively configured to rotate the support 52, move the movable part 551 linearly in the vertical direction, move the movable part 571 linearly in the vertical direction, and move the movable part 581 linearly in the vertical direction.

[0056] <Tape pressing unit 60> As shown in FIG. 8-1, the tape pressing unit 60 includes a tape pressing block 61 that presses the adhesive tape T against the underside of the electric wire W1b of the first workpiece W1, and a rotation drive unit 62 that rotates the tape pressing block 61 in the vertical direction.

[0057] The tape pressing block 61 has a generally L-shaped outer shape. One end of the tape pressing block 61 is attached to a shaft member 621 of the rotation drive unit 62 arranged at the bottom of the first work right side support block 15. The shaft member 621 can rotate clockwise and counterclockwise around a predetermined rotation axis extending in the front-rear direction by the power of the rotation drive unit 62. When the shaft member 621 rotates, the other end of the tape pressing block 61 rotates by a predetermined angle in the vertical direction with the shaft member 621 as a fulcrum. When the other end of the tape pressing block 61 rotates from the bottom to the top, the lower surface (non-adhesive surface) of the adhesive tape T pulled out from the tape winding unit 40 is pushed up by the other end of the tape pressing block 61, and the upper surface (adhesive surface) of the adhesive tape T is pressed against the lower surface of the electric wire W1b of the first work W1.

[0058] The rotation drive unit 62 is fixed to a side surface of the first workpiece right side support block 15, and is fixed to a movable part 711 of the left-right slide drive unit 71 of the base unit 70 via the first workpiece right side support block 15. The rotation drive unit 62 is composed of a power source such as a motor or an arbitrary drive mechanism, and is configured to rotate a shaft member 621.

[0059] <Configuration of base unit 70> As shown in FIG. 2, the base unit 70 includes a left / right slide drive unit 71 that moves the first work holding unit 10 (10a, 10b), the second work positioning unit 20, the second work holding unit 30, and the tape pressing unit 60 together in the left / right direction, a front / rear slide drive unit 72 that moves all of these components together in the front / rear direction, and a base 73 that supports the left / right slide drive unit 71 and the front / rear slide drive unit 72.

[0060] 8-1, the left-right slide drive unit 71 is fixed to a movable part 721 of the front-rear slide drive unit 72. The front-rear slide drive unit 72 is fixed to a base 73. The first work holding unit 10 (10a, 10b), the second work positioning unit 20, the second work holding unit 30, and the tape pressing unit 60 are fixed to a movable part 711 of the left-right slide drive unit 71 and can move in the left-right direction together with the movable part 711 of the left-right slide drive unit 71. They are further fixed to the movable part 721 of the front-rear slide drive unit 72 via the left-right slide drive unit 71 and can move in the front-rear direction together with the movable part 721 of the front-rear slide drive unit 72.

[0061] The left / right slide drive unit 71 and the front / back slide drive unit 72 are composed of a power source such as a motor or an arbitrary drive mechanism, and are configured to respectively move the movable part 711 linearly in the left / right direction and move the movable part 721 linearly in the front / back direction.

[0062] <Other configurations> The tape winding device 1 has a control unit (not shown), and via this control unit, the operation of the first work holding unit 10 (10a, 10b), the second work positioning unit 20, the second work holding unit 30, the tape winding unit 40, the tape holding unit 50, the tape pressing unit 60, and the base unit 70 is electrically controlled.

[0063] 10-1 to 10-38 are diagrams showing the operation of the tape winding device in the embodiment of the present invention. Explanations of each diagram are given in the paragraph [Brief Description of the Drawings] and are therefore omitted here. Each diagram shows only the essential parts of the configuration related to the operation of the tape winding device in a simplified manner. Below, the operation of the tape winding device 1 in the embodiment of the present invention will be explained using these diagrams and the other diagrams mentioned above as appropriate.

[0064] The tape winding device 1 operates, for example, in sequence according to the following steps 1 to 47 (represented as S1 to S47, respectively) to wind the adhesive tape T around the outer circumferential surface of the electric wire W1b of the first workpiece W1 and the outer circumferential surface of the second workpiece W2.

[0065] <s1> First, as shown in Fig. 8-1, the electronic component body W1a of the first work W1 is placed in advance on the first-work left support block 11 of the first work holding unit 10a, and the connector W1c of the first work W1 is placed in advance on the first-work right support block 15 of the first work holding unit 10b. In this state, as shown in Fig. 10-1(a), the first-work left press plate 12 of the first work holding unit 10a moves a certain distance backward by the operation of the front-rear slide drive unit 14, and comes into sliding contact with the upper surface of the electronic component body W1a of the first work W1. As a result, the electronic component body W1a of the first work W1 is sandwiched between the upper surface of the first-work left support block 11 and the lower surface of the first-work left press plate 12. 10-1(b), the first workpiece right side pressing plate 16 of the first work holding unit 10b moves a certain distance backward by the operation of the front-rear slide drive unit 17 and comes into sliding contact with the upper surface of the connector W1c of the first workpiece W1. As a result, the connector W1c of the first workpiece W1 is clamped between the upper surface of the first workpiece right side support block 15 and the lower surface of the first workpiece right side pressing plate 16.

[0066] <s2> 10-2, the first work left support block 11 of the first work holding unit 10a moves slightly leftward by the operation of the left-right slide drive unit 13. As a result, the electronic component body W1a of the first work W1 moves slightly leftward, and the tension acting on the electric wire W1b of the first work W1 increases by that amount.

[0067] <s3> Next, as shown in FIG. 10-3(a), the second work holding hand 31 of the second work holding unit 30 moves a certain distance backward by the operation of the front-rear slide drive unit 32. As a result, a pair of claws 311 of the second work holding hand 31 faces the second work W2 in the up-down direction. Also, as shown in FIG. 10-3(b), the second work positioning plate 21 of the second work positioning unit 20 moves a certain distance backward by the operation of the front-rear slide drive unit 22. As a result, the electric wire W1b of the first work W1 is inserted near the center of the slit opening 211 provided in the second work positioning plate 21, and the left side surface of the second work positioning plate 21 faces the right side surface of the second work W2.

[0068] <s4> 8-3, the second work positioning plate 21 of the second work positioning unit 20 moves a certain distance to the left by the operation of the left-right slide drive part 23. As a result, the left side surface of the second work positioning plate 21 abuts against the right side surface of the second work W2, and accordingly the left side surface of the second work W2 abuts against the right side surface of the electronic component body W1a of the first work W1, and the second work W2 is positioned with respect to the electronic component body W1a of the first work W1.

[0069] <s5> 10-4, the pair of claws 311 of the second work holding hand 31 of the second work holding unit 30 move toward each other by a certain distance. As a result, the second work W2 is gripped from above and below by the pair of claws 311 of the second work holding hand 31.

[0070] <s6> Next, the second work positioning plate 21 of the second work positioning unit 20 moves a certain distance to the right by the operation of the left-right slide drive part 23. As a result, the second work positioning plate 21 moves away from the right side surface of the second work W2, and the second work positioning plate 21 moves to a predetermined position in the right direction (the position shown in FIG. 10-3(b)).

[0071] <s7> 10-5, the second work positioning plate 21 of the second work positioning unit 20 moves a certain distance forward by the operation of the front-rear slide drive part 22. As a result, the second work positioning plate 21 moves away from the electric wire W1b of the first work W1, and the second work positioning plate 21 moves to a predetermined position in the forward direction.

[0072] <s8> Next, the first work holding units 10a and 10b and the second work holding unit 30 move integrally to the right by a fixed distance by the operation of the left-right slide drive unit 71. As a result, the first work W1 and the second work W2 move integrally to the right by a fixed distance, and the electric wire W1b of the first work W1 extending rightward from the right end portion of the second work W2 moves to a position generally facing the tape guide roller 42 of the tape winding unit 40.

[0073] <s9> Next, the first work holding units 10a and 10b and the second work holding unit 30 move integrally a certain distance in the rear direction by the operation of the front-rear slide drive unit 72. As a result, as shown in FIG. 10-6, the first work W1 and the second work W2 move integrally a certain distance in the rear direction, and the electric wire W1b of the first work W1 extending rightward from the right end portion of the second work W2 moves to a position generally close to the tape winding unit 40 and the tape holding unit 50.

[0074] <s10> Next, the first work holding units 10a and 10b and the second work holding unit 30 are moved integrally rearward by a certain distance further by the operation of the front-rear slide drive unit 72. As a result, as shown in Fig. 10-7, the electric wire W1b of the first work W1 extending rightward from the right end portion of the second work W2 is inserted near the center of the slit opening 431 provided in the rotating plate 43 of the tape winding unit 40 and the slit opening 441 provided in the rotating drive unit 44.

[0075] <s11> 10-8, the tape pressure roller 51, tape support block 54, and tape cutter 56 of the tape holding unit 50 move upward a fixed distance together by the operation of the vertical slide drive unit 58. As a result, the adhesive tape T sandwiched between the tape pressure roller 51 and the tape support block 54 moves upward a fixed distance, and the upper surface of the adhesive tape T approaches the lower surface of the electric wire W1b of the first work W1. At this time, the lower surface of the tape pressure roller 51 is disposed at the same height as the lower surface of the electric wire W1b of the first work W1.

[0076] <s12> Next, as shown in FIG. 10-9, the rotating plate 43 of the tape winding unit 40 is rotated by a certain angle counterclockwise as viewed from the right by the operation of the rotation drive unit 44. As a result, the tape guide roller 42 of the tape winding unit 40 moves upward by a certain distance, and the upper surface of the adhesive tape T comes closer to or slightly contacts the lower surface of the electric wire W1b of the first work W1. At this time, the lower surface of the tape guide roller 42 is disposed at the same height as the lower surface of the electric wire W1b of the first work W1. Therefore, the adhesive tape T is disposed substantially horizontally between the tape guide roller 42 and the tape presser roller 51.

[0077] <s13> Next, the tape pressing block 61 of the tape pressing unit 60 rotates a certain angle clockwise as viewed from the front by the operation of the rotation drive part 62, and accordingly, the tip of the tape pressing block 61 moves a certain distance upward as shown in Fig. 10-10. As a result, the adhesive tape T is pressed against the lower surface of the electric wire W1b of the first workpiece W1 by the tip of the tape pressing block 61, and the upper surface (adhesive surface) of the adhesive tape T is affixed to the lower surface of the electric wire W1b of the first workpiece W1.

[0078] <s14> 10-11, the rotating plate 43 of the tape winding unit 40 rotates a certain angle clockwise as viewed from the right by the operation of the rotation drive unit 44. This causes the tape guide roller 42 of the tape winding unit 40 to move downward a certain distance, and accordingly the right side of the adhesive tape T moves downward a certain distance.

[0079] <s15> 10-12, the tape support block 54 of the tape holding unit 50 moves a certain distance downward by the operation of the vertical slide drive part 55. As a result, the tape support block 54 moves away from the adhesive tape T and moves downward to a predetermined position.

[0080] <s16> 10-13, the tape pressure roller 51, tape support block 54, and tape cutter 56 of the tape holding unit 50 move downward integrally by a certain distance by the operation of the vertical slide drive unit 58. As a result, the tape pressure roller 51 moves away from the adhesive tape T, and the tape pressure roller 51, tape support block 54, and tape cutter 56 each move downward to a predetermined position. At this time, the tape pressure roller 51 passively rotates counterclockwise as viewed from the right while in contact with the upper surface (adhesive surface) of the adhesive tape T due to adhesive force, and eventually separates from the upper surface (adhesive surface) of the adhesive tape T.

[0081] <s17> 10-14, the tape pressure roller 51 of the tape holding unit 50 is rotated by an angle of 90° counterclockwise as viewed from above, with the support pillar 52 as a fulcrum, by the operation of the rotation drive unit 53. As a result, the tape pressure roller 51 extends rearward from the support pillar 52.

[0082] <s18> 10-15, the rotating plate 43 of the tape winding unit 40 rotates 180° counterclockwise (half a turn) as viewed from the right by the operation of the rotation drive unit 44. As a result, the adhesive tape T is locally wound around the outer circumferential surface of the electric wire W1b of the first workpiece W1.

[0083] <s19> Next, the tape pressing block 61 of the tape pressing unit 60 rotates a certain angle counterclockwise as viewed from the front by the operation of the rotation drive part 62, and accordingly, the tip of the tape pressing block 61 moves a certain distance downward as shown in Fig. 10-16. As a result, the tip of the tape pressing block 61 moves away from the adhesive tape T and moves downward to a predetermined position.

[0084] <s20> 10-17, the rotating plate 43 of the tape winding unit 40 rotates counterclockwise at an angle of 360° as viewed from the right by the operation of the rotation drive unit 44. As a result, the adhesive tape T is wound around the outer peripheral surface of the electric wire W1b of the first workpiece W1 by 3 to 4 rotations, and the adhesive tape T is firmly fixed to the outer peripheral surface of the electric wire W1b of the first workpiece W1.

[0085] <s21> Next, the first work holding units 10a and 10b and the second work holding unit 30 move integrally a fixed distance forward by the operation of the front-rear slide drive unit 72. As a result, as shown in Fig. 10-18, the first work W1 and the second work W2 move integrally a fixed distance forward, and the adhesive tape T is pulled out forward from the tape reel 41 of the tape winding unit 40 by that distance.

[0086] <s22> Next, the first work holding units 10a and 10b and the second work holding unit 30 move integrally a certain distance in the rear direction by the operation of the front-rear slide drive unit 72. As a result, as shown in Fig. 10-19, the first work W1 and the second work W2 move integrally a certain distance in the rear direction, and the adhesive tape T is bent by that amount, and the tension acting on the adhesive tape T is reduced.

[0087] <s23> Next, as shown in FIG. 8-5, the second work holding hand 31 of the second work holding unit 30 moves a certain distance to the right by the operation of the left-right slide drive part 33. As a result, the second work W2 moves a certain distance to the right along the outer circumferential surface of the electric wire W1b of the first work W1, and the right side surface of the second work W2 strongly abuts against the left side surface of the adhesive tape T so as to slightly bite into it, and as shown in FIG. 10-20, a deformed part Ta is formed in the adhesive tape T due to curvature or bending, and a part of this deformed part Ta is relatively pressed into the gap between the outer circumferential surface of the electric wire W1b of the first work W1 and the inner circumferential surface of the second work W2. At this time, the distance by which the deformed part Ta of the adhesive tape T is pressed into the gap between the outer circumferential surface of the electric wire W1b of the first work W1 and the inner circumferential surface of the second work W2 is, for example, about half the width of the adhesive tape T.

[0088] <s24> 10-21, the rotating plate 43 of the tape winding unit 40 rotates 360° counterclockwise as viewed from the right, 3 to 4 times, by the operation of the rotation drive unit 44. As a result, the adhesive tape T is wound 3 to 4 times so as to straddle the outer circumferential surface of the electric wire W1b of the first work W1 extending rightward from the right end portion of the second work W2 and the outer circumferential surface of the right end portion of the second work W2.

[0089] <s25> Next, the first work holding units 10a and 10b and the second work holding unit 30 move integrally to the right at a constant speed by the operation of the left-right slide drive unit 71, while the rotating plate 43 of the tape winding unit 40 rotates a predetermined number of times through an angle of 360° counterclockwise as viewed from the right by the operation of the rotation drive unit 44. As a result, while the first work W1 and the second work W2 move integrally to the right at a constant speed, the adhesive tape T is spirally wound without gaps from the outer circumferential surface of the right end part of the second work W2 to the outer circumferential surface of approximately the center part of the second work W2.

[0090] <s26> 10-22, the pair of claws 311 of the second workpiece holding hand 31 of the second workpiece holding unit 30 move in directions away from each other. As a result, the second workpiece W2 is released from the constraint by the claws 311 of the second workpiece holding hand 31.

[0091] <s27> 10-23, the second work holding hand 31 of the second work holding unit 30 moves a certain distance forward by the operation of the front-rear slide drive part 32. As a result, the second work holding hand 31 moves away from the second work W2 and moves to a predetermined position in the forward direction.

[0092] <s28> Next, the second work holding hand 31 of the second work holding unit 30 moves a certain distance to the left by the operation of the left-right slide drive part 33. As a result, the second work holding hand 31 moves to a predetermined position in the left direction.

[0093] <s29> Next, as shown in Fig. 10-24, the first work holding units 10a and 10b move integrally to the right at a constant speed by the operation of the left-right slide drive unit 71, while the rotating plate 43 of the tape winding unit 40 rotates a predetermined number of times through an angle of 360° in a counterclockwise direction as viewed from the right by the operation of the rotation drive unit 44. As a result, while the first work W1 and the second work W2 move integrally to the right at a constant speed, the adhesive tape T is spirally wound without gaps from the outer circumferential surface of the approximately central part of the second work W2, via the outer circumferential surface of the left end part of the second work W2, and over the outer circumferential surface of the electric wire W1b of the first work W1 extending leftward from the left end part of the second work W2.

[0094] <s30> Next, the rotating plate 43 of the tape winding unit 40 rotates 360° counterclockwise as viewed from the right three or four times by the operation of the rotation drive part 44. As a result, the adhesive tape T is wound three or four times around the outer peripheral surface of the electric wire W1b of the first work W1 extending leftward from the left end part of the second work W2.

[0095] <s31> Next, as shown in FIG. 10-25, the first work holding units 10a and 10b are moved slightly to the left together by the operation of the left-right slide drive unit 71. As a result, the first work W1 and the second work W2 are moved slightly to the left together, and accordingly, the adhesive tape T wound around the electric wire W1b of the first work W1 extending leftward from the left end of the second work W2 is moved slightly to the left, and the adhesive tape T extends straight forward from the outer circumferential surface of the electric wire W1b of the first work W1 toward the tape guide roller 42. In addition, in the state immediately before this operation, the adhesive tape T extends slightly obliquely from the tape guide roller 42 toward the right side of the electric wire W1b of the first work W1 due to the influence of the adhesive tape T spirally wound around the outer circumferential surfaces of the first work W1 and the second work W2. If this state is maintained, there is a risk that the adhesive tape T cannot be reliably cut in S40 described later.

[0096] <s32> Next, the first work holding units 10a and 10b are moved integrally forward by a certain distance by the operation of the front-rear slide drive unit 72. As a result, the electric wire W1b of the first work W1 and the second work W2 are moved integrally from the inside to the outside of the slit opening 431 provided in the rotating plate 43 of the tape winding unit 40, and the adhesive tape T is pulled out from the tape reel 41 by that amount.

[0097] <s33> 10-27, the tape pressure roller 51, tape support block 54, and tape cutter 56 of the tape holding unit 50 move integrally upward a certain distance by the operation of the vertical slide drive unit 58. As a result, the lower surface of the tape pressure roller 51 is positioned slightly higher than the upper surface of the adhesive tape T.

[0098] <s34> 10-28, the tape pressure roller 51 of the tape holding unit 50 is rotated by an angle of 90° clockwise as viewed from above around the support post 52 by the operation of the rotation drive unit 53. As a result, the lower surface of the tape pressure roller 51 faces the upper surface of the adhesive tape T.

[0099] <s35> 10-29, the tape pressure roller 51, tape support block 54, and tape cutter 56 of the tape holding unit 50 move downwards a certain distance together by the operation of the vertical slide drive unit 58. As a result, the lower surface of the tape pressure roller 51 approaches the upper surface of the adhesive tape T.

[0100] <s36> 10-30, the first work holding units 10a and 10b are moved slightly backward by the operation of the front-rear slide drive unit 72. As a result, the electric wire W1b of the first work W1 and the second work W2 are moved slightly backward, and the adhesive tape T is slightly bent.

[0101] <s37> 10-31, the rotating plate 43 of the tape winding unit 40 rotates a certain angle counterclockwise as viewed from the right by the operation of the rotation drive unit 44. As a result, the tape guide roller 42 moves a certain distance upward, and the upper surface of the adhesive tape T comes close to or slightly contacts the lower surface of the tape pressure roller 51 of the tape holding unit 50.

[0102] <s38> 10-32, the tape support block 54 of the tape holding unit 50 moves a certain distance upward by the operation of the vertical slide drive unit 55. As a result, the adhesive tape T is clamped between the lower surface of the tape pressure roller 51 and the upper surface of the tape support block 54.

[0103] <s39> Next, the first work holding units 10a and 10b are moved integrally a certain distance forward by the operation of the front-rear slide drive unit 72. As a result, as shown in Fig. 10-33, the electric wire W1b of the first work W1 and the second work W2 are moved integrally a certain distance forward, and the tension acting on the adhesive tape T is increased.

[0104] <s40> 10-34, the tape cutter 56 of the tape holding unit 50 moves a certain distance upward by the operation of the vertical slide drive part 57. As a result, the adhesive tape T is cut by the tape cutter 56 between the electric wire W1b of the first workpiece W1 and the tape presser roller 51 and tape support block 54.

[0105] <s41> 10-35, the tape cutter 56 of the tape holding unit 50 moves a certain distance downward by the operation of the vertical slide drive unit 57. As a result, the tape cutter 56 moves away from the adhesive tape T and moves downward to a predetermined position.

[0106] <s42> Next, as shown in Fig. 10-36, the rotating plate 43 of the tape winding unit 40 rotates a certain angle clockwise as viewed from the right by the operation of the rotation drive unit 44. This causes the rotating plate 43 to move to the initial position.

[0107] <s43> Next, the first workpiece holding units 10a and 10b are moved integrally forward by a certain distance by the operation of the front-rear slide drive unit 72. As a result, the first workpiece W1 and the second workpiece W2 are moved integrally forward by a certain distance, as shown in FIG.

[0108] <s44> Next, the first workpiece holding units 10a and 10b are moved integrally to the left by a fixed distance by the operation of the left-right slide drive unit 71. As a result, the first workpiece W1 and the second workpiece W2 are moved integrally to the left by a fixed distance.

[0109] <s45> Next, the first work left support block 11 of the first work holding unit 10a moves slightly to the right by the operation of the left-right slide drive unit 13. As a result, the electronic component body W1a of the first work W1 moves slightly to the right, and the tension applied to the electric wire W1b of the first work W1 is released.

[0110] <s46> Next, the first work left side pressing plate 12 of the first work holding unit 10a moves a fixed distance forward by the operation of the front-rear slide drive unit 14, and the first work right side pressing plate 16 of the first work holding unit 10b moves a fixed distance forward by the operation of the front-rear slide drive unit 17. As a result, the first work left side pressing plate 12 moves away from the top surface of the electronic component body W1a of the first work W1, and the first work right side pressing plate 16 moves away from the top surface of the connector W1c of the first work W1, making it possible to remove the first work W1 from the first work left side support block 11 and the first work right side support block 15.

[0111] <s47> Finally, as shown in Figure 10-38, the tape pressure roller 51, tape support block 54 and tape cutter 56 of the tape holding unit 50 move downward a certain distance by the operation of the vertical slide drive unit 58. This returns the tape winding device 1 to its initial state.

[0112] After S47 is completed, the first work W1 and the second work W2 around which the adhesive tape T is wound are manually or automatically removed from the tape winding device 1. Then, as necessary, new first work W1 and second work W2 around which the adhesive tape T is not wound are manually or automatically supplied to the tape winding device 1, and S1 to S47 are performed again.

[0113] S1 to S47 are merely examples of the operations of the tape winding device 1, and various modifications are possible. For example, some of S1 to S47 can be performed at the same time or in a different order, as long as they do not interfere with each other's operations.

[0114] <Effects of tape winding device 1> According to the tape winding device 1, for example, the following effects can be obtained.

[0115] The second work holding hand 31 of the second work holding unit 30 moves the second work W2 along the outer peripheral surface of the electric wire W1b of the first work W1 and abuts the second work W2 against the side of the adhesive tape T to form a deformed portion Ta of the adhesive tape T, and a portion of this deformed portion Ta is relatively pushed into the gap between the outer peripheral surface of the electric wire W1b of the first work W1 and the inner peripheral surface of the second work W2.Therefore, the tape winding device 1 can wind the adhesive tape around the outer peripheral surface of the electric wire W1b of the first work W1 and the outer peripheral surface of the second work W2 while reliably inserting a portion of the adhesive tape T into the gap between the outer peripheral surface of the electric wire W1b of the first work W1 and the outer peripheral surface of the second work W2.

[0116] Since the second work positioning plate 21 of the second work positioning unit 20 positions the second work W2 relative to the first work W1, the tape winding device 1 can accurately move the second work W2 based on that position and properly abut the second work W2 against the adhesive tape T.

[0117] Since the tape pressing roller 51 and tape support block 54 of the tape holding unit 50 clamp the adhesive tape T, the tape winding device 1 can stably attach the adhesive surface of the adhesive tape T pulled out from the tape winding unit 40 to the electric wire W1b of the first workpiece W1, and can also stably cut the adhesive tape T pulled out from the tape winding unit 40.

[0118] Since the tape pressure roller 51 of the tape holding unit 50 rotates while contacting the adhesive surface of the adhesive tape T, the tape winding device 1 can separate the tape pressure roller 51 from the adhesive surface of the adhesive tape T without applying a large load to the adhesive tape T. On the other hand, since the flat surface of the tape support block 54 supports the non-adhesive surface of the adhesive tape T, the tape winding device 1 can stably hold the adhesive tape T.

[0119] Since the tape pressure roller 51 of the tape holding unit 50 rotates about the support pillar 52 as a fulcrum, the tape winding device 1 can easily switch between a state in which the tape pressure roller 51 faces the adhesive surface of the adhesive tape T and a state in which the tape pressure roller 51 does not face the adhesive surface of the adhesive tape T. This contributes to simplifying the configuration of the tape winding device 1 and improving the freedom of design.

[0120] Since the tape pressing block 61 of the tape pressing unit 60 presses the adhesive surface of the adhesive tape T against the electric wire W1b of the first workpiece W1, the tape winding device 1 can reliably apply the adhesive tape T to the electric wire W1b of the first workpiece W1.

[0121] The left-right slide drive unit 71 and the front-rear slide drive unit 72 of the base unit 70 move the first work holding unit 10 (10a, 10b) and the second work holding unit 30 in the left-right direction and the front-rear direction together, so that the tape winding device 1 can operate with a high degree of freedom. In contrast, the tape winding unit 40 is fixed to the base 73 of the base unit 70 so as not to move in the left-right direction and the front-rear direction, so that the configuration of the tape winding device 1 can be simplified compared to a case in which the tape winding unit 40 is configured to move in the left-right direction and the front-rear direction. In other words, the first work holding unit 10 (10a, 10b) and the second work holding unit 30 are configured to move in the left-right direction and the front-rear direction together, and the tape winding unit 40 is fixed to a predetermined position so as not to move, so that the tape winding device 1 can operate with a high degree of freedom with a simple configuration. Furthermore, the second work positioning unit 20 and the tape pressing unit 60 are configured to move integrally in the left-right and front-back directions together with the first work holding unit 10 (10a, 10b) and the second work holding unit 30 by the left-right slide drive unit 71 and front-back slide drive unit 72 of the base unit 70, and the tape holding unit 50, like the tape winding unit 40, is fixed to a predetermined position so as not to move, so that the tape winding device 1 can operate with even greater freedom with a simple configuration.

[0122] The operation of S2 increases the tension acting on the electric wire W1b of the first workpiece W1, so that the tape winding device 1 can properly wind the adhesive tape T around the outer peripheral surface of the electric wire W1b of the first workpiece W1.

[0123] The operations S21 to S22 reduce the tension acting on the adhesive tape T, so that in S23, the tape winding device 1 can easily deform the adhesive tape T to form a deformed portion Ta of an appropriate shape, and reliably press this deformed portion Ta into the gap between the outer peripheral surface of the electric wire W1b of the first work W1 and the inner peripheral surface of the second work W2.

[0124] The operation of S31 causes the adhesive tape T to extend straight from the outer peripheral surface of the electric wire W1b of the first workpiece W1 toward the tape guide roller 42, so that the tape winding device 1 can reliably cut the adhesive tape T in S40.

[0125] The present invention is not limited to the above-mentioned embodiment, and may have various other embodiments. The work is not limited to the above-mentioned first work W1 (electronic component) and second work W2 (resin tube), and may be other. [Explanation of symbols]
