Definitions

  • the present invention relates to a stator core having a central hole and slots around the central hole, and a wire bundle separation device and wire bundle separation method for separating the wire bundle from a stator having wire bundles bonded in the slots.
  • xEVs Cars that run on electricity can be broadly categorized into four types, but these are collectively referred to as xEVs.
  • Hybrid cars were the first to be sold commercially, but 20 years have passed since their release, and establishing recycling technology for xEVs is becoming a major challenge.
  • the challenge which differs greatly from the dismantling and recycling of conventional automobiles, is the dismantling and recycling of batteries and xEV motors.
  • the black motor is a device that compresses refrigerant gas to high pressure, and the motor and compressor are sealed together in a welded iron container called a shell.
  • the only inputs and outputs from this shell are the gas intake port, discharge port, and electrical leads, and it is completely sealed to prevent gas leaks. For this reason, it is not easy to dismantle it.
  • the other method is to melt or mechanically cut the shell of the black motor, remove the contents, and then disassemble it into smaller pieces.
  • the dismantling process for the black motor is outlined below.
  • First process Cutting the shell of the black motor. For rotary type black motors, two locations are cut, one at the top and one at the bottom, while for reciprocating type black motors, one location is cut along the circumference. There are several cutting methods, such as melting with gas or plasma, cutting by cutting, or cutting by the bite of a rotary blade using plastic deformation.
  • Second step Separating the motor part from the compressor. Remove the stator with the wires wound around it.
  • Third step Cutting the conductor. Cut one of the conductors at both ends of the stator along the stator surface.
  • Fourth step Pulling out the conductor. Fix the stator and grab the conductor coming out from the other end of the cut conductor and pull it out.
  • FIGS 1(a)-(f) show various stators 1 for xEV motors (reference numbers for each component of stator 1 are only given in Figure 1(a)).
  • Stator core 2 is made up of several hundred stacked silicon steel sheets with a thickness of about 0.1 mm, with round or square conductor wires wound according to a set rule between multiple slots 2b, and upper conductor wires 4U and lower conductor wires 4L exposed on the upper and lower stator surfaces 3U and 3L of stator core 2.
  • both the top and bottom are fixed to the circumference with string or the like, while in the case of square conductors, since they do not have the flexibility of round conductors, the top and bottom conductors are joined together by welding or other methods.
  • Square conductors are the mainstream for xEV motors because they can handle a higher current density.
  • the stator of the black motor can be carried by hand, but the stator 1 of the xEV motor weighs a maximum of 20 kg or more, and although it may be feasible in an experimental sense, it is commercially impossible to move, lift, turn over, and perform other tasks by hand on a continuous basis.
  • xEV motors are mainly used in passenger cars, but xEV motors for transport trucks, etc., which are expected to become more widespread in the future, are expected to become even larger and heavier.
  • Experiment 1 Pull-out method After cutting the winding (upper conductor 4U or lower conductor 4L) extending outward from either the upper or lower stator surface 3U, 3L of the stator core 2 along the stator surface 3U or 3L, a 60-degree circumference of the conductor protruding from the other stator surface 3U or 3L was gripped with a powerful hydraulic gripping mechanism, and several points on the stator surfaces 3U, 3L in the vicinity were pressed down to receive the reaction force when pulling out. When the gripping mechanism was lifted with a maximum thrust of 2000 kg, it was confirmed that the conductor was lifted slightly out of the stator 1. This proves that the gripping force and thrust are sufficient to move the conductor inside the stator 1.
  • Experiment 2 Method for press-extrusion of conductors in slots 2b
  • the upper conductors 4U and the lower conductors 4L at both ends of the stator 1 were cut along the stator faces 3U and 3L to make the slots 2b look neat.
  • a bundle of conductors 4M (not shown in FIG. 1 / see FIG. 2) adhered with resin or the like was left in the slots 2b.
  • the stator 1 that has been processed in this way will be referred to as the processed stator 1A.
  • a hole larger than the slot 2b was drilled in the reference face, the processed stator 1A was placed on the reference face with the slots 2b and the hole aligned, and a press rod was hydraulically pressed in from above the slots 2b.
  • the silicon steel plate was not deformed because the periphery of the slots 2b was supported in contact with the reference face, and it was possible to press out the plate by applying an appropriate force to the press rod.
  • Experiment 1 was performed in a 60-degree range of the processed stator 1A (8 to 12 slots 2b), but as in experiment 2, if it was performed for each slot 2b, it was possible to push out the conductor bundle 4M with a much smaller force.
  • the height 5 of the slot 2b is considerably longer than the cross-sectional dimension of the slot 2b. Therefore, when a long and thin press bar is inserted into the slot 2b with a large force, the part inserted into the slot 2b is guided by the inner wall of the slot 2b and does not bend. However, when the press bar starts to be inserted into the slot 2b, most of the press bar is exposed from the slot 2b, so there is a problem that the press bar buckles due to pressure. In experiment 2, a method was used in which multiple short bars were inserted in sequence, so buckling did not occur, but it is difficult to adopt a similar method in commercial equipment.
  • Task 4 When the outer diameter of the stator 1 is chucked, the chuck mechanism (chuck housing, etc.) completely shields the top and bottom surfaces of the stator, and the conductor bundle 4M in the slot 2b cannot be pressed out due to interference with the chuck mechanism.
  • the slot 2b In order to maximize the magnetic efficiency, the slot 2b is close to the inner diameter of the stator 1 as shown in Figure 1. Therefore, even when the central hole 2a is chucked from the inside, if the chuck mechanism becomes even slightly larger outside the central hole 2a, the pressed out conductor bundle 4M will interfere.
  • Task 5 When the press rod is pressed into the specified slot 2b while the inner or outer diameter of the stator 1 is chucked, the press force is applied to the entire chuck mechanism. If the chuck force is weak, the stator 1 may shift or tilt. On the other hand, if the chuck force is too strong, the silicon steel plate may be deformed.
  • Task 6 In order to press and push out the conductor bundle 4M in the slot 2b without deforming the silicon steel plate, a support that firmly supports the stator core around the slot is required. In order to separate the conductor bundle 4M from multiple slots, the stator needs to be rotated each time the conductor bundle 4M of each slot is separated, but it is not preferable for the stator to come into contact with the support during rotation.

  • Step 5 The pressing start position of the press bar 34 and the driving distance of the press actuator 31 according to the height 5 of the stator 1 may be stored in advance in a storage medium or the like.
  • the treated stator 1A can be freely moved on the table 60 without interfering with the chuck housing 15, the support 37, the press rod 34, and other members (see the arrow in FIG. 3).
  • Step 6 The treated stator 1A is slid on the table 60 and placed at the position of the opening 61a.
  • Step 7 The chuck unit 10 is raised to the first operating height H1 by driving the linear actuator 23. This causes the chuck jaws 11 to rise to a height at which they can chuck the central hole 2a.
  • Step 8 The tapered shaft 17 is raised by driving the fluid pressure actuator 28. As a result, the chuck jaws 11 move radially outward and come into contact with the inside of the central hole 2a of the treated stator 1A, and the treated stator 1A is chucked.
  • Step 9 The chuck unit 10 is raised to the second operating height H2 by driving the linear actuator 23.
  • Step 10 The press unit 30 is advanced along the linear guide 39 to a prescribed position according to the type of the treated stator 1A. Fine adjustment may be performed manually. If the rotational position of the treated stator 1A is misaligned, the rotary actuator 21 is rotated so that the slot 2b is positioned on the axis L. The rotation may be performed manually, and the alignment may be judged visually.
  • Step 11 for extruding and separating the conductor bundle 4M The press actuator 31 is driven to lower the press rod 34 in accordance with the following steps 11-1 and 11-2.
  • Step 11-2 When the upper surface 37b of the support 37 comes into contact with the lower surface of the stator core 2, the press unit 30 stops rising and, instead, the press bar 34 starts to fall from the contact position. Since the lower surface of the stator core 2 is supported by the upper surface 37b of the support 37 and cannot move downward, the press bar 34 enters the slot 2b and pushes the conductor bundle 4M from the slot 2b into the cavity 37a. Since the periphery of the slot 2b is supported by the upper surface 37b of the support 37, deformation of the silicon steel plate and the resulting deformation of the shape of the slot 2b can be prevented.
  • Step 12 When the extrusion of the conductor bundle 4M is completed, the press actuator 31 is driven to raise the press rod 34 to the initial position. The completion of the extrusion can be determined by measuring the height position of the press rod 34 by the linear position sensor 32 and comparing it with the driving distance of the press actuator 31 that is stored in advance for each type of processed stator 1A.
  • Step 13 After confirming that the press rod 34 has risen to the initial position, the rotary actuator 21 is driven to rotate the chuck unit 10 (processed stator 1A) to a position where the next slot 2b coincides with the axis L of the press rod 34. As described in step 9, the processed stator 1A can rotate freely.
  • Step 14 Thereafter, steps 11 to 13 are repeated to separate the conductor bundles 4M in all slots 2b.
  • Step 15 Opening and carrying out the processed stator 1A :
  • the linear actuator 23 lowers the chuck unit 10 to the first operating height H1, and then the fluid pressure actuator 28 lowers the tapered shaft 17 to release the chuck of the processed stator 1A by the chuck unit 10, and then the linear actuator 23 lowers the chuck unit 10 to the origin height H0.
  • the press unit 30 may be retreated on the linear guide 39 to the retracted position.
  • the treated stator 1A is slid on the table 60 by using the rolling of the rollers 65, 66 and is carried out of the apparatus.
  • steps 6 to 16 can be automatically operated by controlling actuators 21, 23, 28, 31, etc., using a control device or the like. In particular, it is preferable to automatically operate steps 11 to 15.
  • the wire bundle 4M is pushed out of the slot 2b by inserting the press rod 34 into the slot 2b while the underside of the stator core 2 (around the slot 2b) is supported by a support 37 having a hollow portion 37a through which the wire bundle 4M on the axis L of the press rod 34 can pass.
  • the stay 33 is guided by the linear guide 36 so that it can move up and down

Because the underside of the stator core 2 is supported by the support 37, it is possible to push out and separate the conductor bundle 4M with almost no external force acting on the stator core 2 or the chuck jaws 11.
  • the chuck housing 15 can pass through the central hole 2a, and the chuck claws 11 engage with the central hole 2a from the inside to chuck the processed stator 1A, and the linear actuator 23 can move the chuck housing 15 up and down between the origin height H0, the first operating height H1, and the second operating height H2. This prevents the chuck housing 15 from blocking the slot 2b, and allows the processed stator 1A to be moved on the table 60 without interfering with the chuck housing 15, and also allows the processed stator 1A to be rotated without coming into contact with the table 60.
  • the chuck jaws 11 are driven radially outward by sliding the cam follower 12 on a tapered shaft that moves up and down using the fluid pressure actuator 28 in the central shaft hole of the chuck housing, which prevents excessive gripping force from being applied to the processed stator 1A when chucking the processed stator 1A, preventing deformation of the silicon steel plate or slot 2b due to excessive gripping force and the resulting difficulty in extruding and separating the conductor bundle 4M.
  • the fluid pressure actuator 28 be of the pneumatic type and be operated at a pre-adjusted pressure.
  • a hollow rotating shaft is provided in the rotary actuator 21, a drive fluid line 20 is passed through the hollow rotating shaft, and both ends of the drive fluid line 20 are connected to the fluid pressure actuator 28 and the swivel joint 22, making it possible to supply working fluid to the fluid pressure actuator 28, which moves up and down and rotates.
  • a guide member 35 having a guide hole 35a is provided on the axis L, and the base end 34b of the press rod 34 has a larger moment of area than the tip end 34a.
  • the guide hole 35a has a cross-sectional shape that allows both the tip end 34a and the base end 34b to pass through, making it possible to prevent buckling of the press rod 34 when the conductor bundle 4M is pushed out.
  • the wire bundle separation device 6 and the dimensions, shape, arrangement, number, materials, etc. of those elements described in the above embodiment are merely examples, and other configurations are possible.
  • the table 60 and linear guide 39, etc. can be omitted, and since there is no need to move the chuck unit 10 from the second operating height H2, the linear actuator 23 can also be omitted.
  • the chuck unit 10 can be omitted.
