The cleaning device 100 for a traction motor according to the present invention includes a supporting means 200, a conveying means 300, a turntable 400 and a stopper means 500 as shown in FIGS. 2A and 2B .

The supporting means 200 is a means in which the conveying means 300 is installed and the turntable 400 is mounted. The supporting means 200 is installed to transfer the pallet 110 on which the stator or the rotor is mounted to the turntable 400 together with the conveying means 300. As shown in FIGS. 2A and 2B, the support means 200 includes a plurality of longitudinal frames 210, a transverse frame 220, and a connection frame 230 interlocked with each other. To be more specific, a plurality of longitudinal frames 210 and transverse frames 220 are fastened in a state of being in a state of being combined with each other, and a plurality of connection frames 230 are fastened across them. In addition, the support means 200 is installed across the support frame 240, which is capable of holding and fixing the turntable 400. The mounting height of the support frame 240 is such that the third support member 423 of the turntable 400 is positioned slightly lower than the conveyor 310 of the conveying means 300 described below. That is, when the pallet 110 transported along the conveyor 310 is positioned on the upper side of the third support member 423, the third support member 423 rises to lift the pallet 110 As shown in FIG.

The conveying means 300 is installed to convey the pallet 110 to which the stator or the rotor is loaded. The conveying means 300 includes a conveyor 310, a guide rail 320, and a pallet 110.

First, the conveyor 310 is mounted on the upper part of the support means 200, and is installed so that the pallet 110 is seated and moved. Thus, the pallet 110 is positioned on the conveyor 310 and enters the turntable 400 or is discharged from the turntable 400.

The guide rail 320 is disposed on the outer side of the conveyor 310 so as to be close to the side surface of the pallet 110 so that the pallet 110 is not released when the pallet 110 is moved. Therefore, when the pallet 110 moves away from the fixed position while moving along the conveyor 310, the pallet 110 is returned to the fixed position by the elasticity of the guide rail 320 while bumping against the guide rail 320.

3A, the pallet 110 includes a stopper hole 112 in which a stopper 510 is received on at least one side, a position fixing protrusion 423b (see FIG. 7A) described later, And at least one protrusion groove 111 into which the protrusion 111 is inserted. Here, the stopper hole 112 can be machined on four sides as in Fig. 3A. This is because the stopper 510 is inserted into the stopper hole 112 regardless of the direction in which the pallet 110 is lifted and rotated by the turntable 400 and placed on the conveyor 310, So that it can be stopped. The depth of the stopper hole 112 in the center direction is set such that the stopper 510 is inserted into the space between these stopper holes 112 when the two pallets 110 are connected to each other and the stopper holes 112 are in contact with each other It is enough to be able to be. The protruding grooves 111 are preferably formed in a hole shape passing through a part of the pallet 110 and may be formed in a groove shape on the lower surface of the pallet 110.

In order to distinguish the special palette 110 of the stator or the rotor, the RFID chip can be fixed or embedded in a part of the pallet 110 by attaching or inserting the RFID chip in a groove (not shown) (Number or symbol) can be displayed on one side of the display unit 110. [ In this pallet 110, a corresponding pallet 110 on which a stator or a rotor can be respectively loaded is separately manufactured. In this case, as shown in FIG. 3A, the pallet 110 on which the stator can be mounted is attached with a reinforcing support 113 made of a rigid material on the top surface to withstand the weight of the stator. 3 (b), the pallet 110 on which the rotors can be mounted is provided with at least two rollers 114 made of or coated with a urethane material or a soft material to protect the insulating paint and coating of the rotor Respectively.

4 and 5, the turntable 400 is lifted up to a predetermined height in a state where a stator or a rotor separated from the traction motor is loaded, and then is rotated clockwise or counterclockwise (hereinafter, Quot;). That is, ultimately, the turntable 400 is configured to be able to clean the entire region while moving the stator or the rotor in the arm movement range of the robot 600 (see FIG. 8) fixed in position. The turntable 400 includes a lifting / lowering means 410 and a rotating means 420. The robot 600 will be described later.

Also, the first driving source may be directly fixed to the supporting means 200 or the first supporting member 411 in a state in which the first supporting member 412a is excluded.

The air tube 412c, which is a lifting / lowering member, is installed to raise / lower the second supporting member 412b mounted on the upper portion while expanding or contracting due to air introduced or discharged from the first driving source. Here, the second supporting member 421 is provided on the second supporting member 412b. In addition, when the lifting / lowering member is a lifting / lowering cylinder, the lifting / lowering member may be installed on the first supporting member 412a or directly on the first supporting member 411 while excluding the first supporting member 412a, The first support member 412a and the first support member 411 may be removed and then installed directly on the support frame 240 of the support means 200. [ Of course, the second supporting member 412b may be installed on the upper portion of the lifting cylinder so as to raise / lower the second supporting member 421 mounted on the second supporting member 412b, The second support member 421 may be directly installed and raised / lowered while the member 412b is omitted.

The second support member 412b is provided to provide uniform upward and downward pressures with respect to a constant contact area of the second support member 421 when the air tube 412c expands and contracts. On the other hand, the second support member 412b may be omitted when the ascending / descending device is a lift / lower cylinder instead of the air tube 412c, and the second support member 421 is directly installed on the ascending / descending cylinder.

4 and 6A, a plurality of the horizontal holding devices 413 are mounted at positions symmetrical to each other with the rim of the second supporting member 412b, And is a device for holding and supporting the support member 421 in the horizontal direction within a certain range of inclination. Here, 'horizontal in a certain inclination range' means that as the second supporting member 421 is inclined, the pallet 110 is inclined with the third supporting member 423 so that the mounted stator or rotor does not fall , Which also applies to the same expressions described below. As shown in FIG. 6C, the horizontal holding device 413 is disposed through the connection box 413a and the connection box 413a. The horizontal holding device 413 includes a lift / lower shaft 413b and a lifting / lowering shaft 413b, A horizontal holding shaft 413c attached to both ends of the horizontal holding gear 413d arranged to be engaged with the mountains of the first and second supporting members 421 and 413b, And a flange 413e. At this time, horizontal holding gears 413d of the horizontal holding shaft 413c are accommodated in the connection box 413a. In addition, the horizontal holding device 413 may be mounted at a portion where the respective components are in contact with each other and where a motion is required. 6A and 6C, the horizontal holding device 413 is installed at the four corners of the second supporting member 421. In this case, More specifically, the connection box 413a, the lifting shaft 413b and the flange 413e are provided on the second support member 421 at each corner of the second support member 421, A horizontal holding shaft 413c is mounted to connect the shaft 413b. At this time, the horizontal holding gears 413d provided at the ends of two adjacent horizontal holding shafts 413c are disposed on one of the up / down shafts 413b, And is arranged to engage with the mountain processed in the step 413b. Therefore, when the ascending / descending axis 413b moves up and down, the two horizontal retaining shafts 413c rotate as the two horizontal retaining gears 413d engaged with the mountain of the ascending / descending axis 413b rotate, When the rotation of each of the horizontal holding shafts 413c rotates the horizontal holding gear 413d located at the other side portion, the other rising / falling shaft 413b is moved up and down by the other horizontal holding gear 413d. That is, when one of the up / down shafts 413b ascends or descends, the remaining three w / o shafts 413a, And the descending axis 413b is raised or lowered to the same height. Due to the operation of the horizontal holding device 413, the second supporting member 421 can be raised / lowered at the same height as the second supporting member 421 to firmly support the horizontal portion of the second supporting member 421 within a predetermined inclination range have.

Also, the rising / falling of the lifting / lowering shaft 413b may be performed as the lifting / lowering of the second supporting member 421 moves. In addition, a second driving source (not shown) for moving the above-described lifting / lowering shaft 413b or rotating the horizontal holding shaft 413c may be separately provided. In this case, the up / down shaft 413b is configured to be raised / lowered by the second drive source in conjunction with the up / down movement of the second support member 421, or the horizontal hold shaft 413c is configured to rotate, 2 supporting member 421 within a certain tilt range. Here, the horizontal support of the second support member 421 within a certain tilt range ultimately supports the weight of the stator or rotor, together with the pallet 110 loaded on the third support member 423, In order to avoid such problems.

The height restricting device 414 is a device for fixing the position of the second support member 421 and for restricting the height of the second support member 421 within a certain range. Thus, the height restricting device 414 can be eliminated. 4 and 6A, the height restricting device 414 is an apparatus that is operated to insert or withdraw the upper portion with respect to the lower portion. The height restricting device 414 is disposed symmetrically between the horizontal holding devices 413, And is firmly fastened to the second support member 421. Therefore, the upper portion of the height restricting device 414 is lifted or lowered along the second supporting member 421 which is ascending / descending, so that the horizontal holding device 413 The height of the second support member 421 with respect to the rise / fall of the second support member 421 is limited within a certain range.
