Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of carbon brush welding, in particular to an automatic screw rod carbon brush welding device. BACKGROUND

[0002] At present, new energy vehicles mainly refer to electric vehicles, and as important components of electric vehicles, the motor needs to ensure the size of the carbon brush and the quality of the brush braid in production and assembly, which plays an important role in the overall quality of the motor. Generally, a connecting rod for adjustment is installed on the brush braid or carbon brush, and the screw rod at the end of the brush braid is welded as an example:

[0003] The existing welding of the screw rod and the carbon brush braid is that one hand puts the screw rod into the welding electrode of the welding machine, and the other hand holds the carbon brush braid on the top of the screw rod, and then the welding machine is used for welding. Although the existing method saves the cost of equipment, this welding method not only has high labor intensity, but also cannot guarantee safety, and manual operation cannot guarantee the consistency of the welding quality, which affects the yield.

[0004] In view of the above situation, at present, there is a lack of corresponding automatic assembly welding device in this welding link, and only the automatic welding technical scheme of the previous welding link can be referred to in the same field, such as Chinese patent CN110640284A-A kind of motor carbon brush braid welding is used automatic pre-welding machine, which specifically is a kind of motor carbon brush braid welding is used automatic pre-welding machine, including operation rack, the upper surface middle part of operation rack is provided with index table, the upper surface edge of index table is provided with material clamping plate at equal distance, the upper surface right end of operation rack is provided with feeding vibration mechanism, the upper surface right side of operation rack is provided with feeding mechanism, the feeding end of feeding mechanism is connected with feeding vibration mechanism, the discharge end of feeding mechanism corresponds with the material clamping plate on index table, the upper surface middle front side of operation rack is provided with wire straightening mechanism.

Two vibrators 203 are installed separately at the lower part of the carbon brush track 204 along the conveying direction. If the carbon brush is placed in the track alone, the posture is easy to change during the vibration discharging process, so two carbon brush track baffles 205 are designed to be placed parallel to the upper end surface of the track, with a gap in the middle to ensure that the brush braid is placed upward and can be translated through. The mounting plate 202 of each vibrator 203 is vertically placed on the workbench 1 through four lead screws 201 arranged at the four corners, so that the inclination angle of the mounting plate 202 can be changed by adjusting the lead screws 201.

Figure 3As shown, the detection track 3 is provided with detection electrodes and position sensors; preferably, the detection track 3 has an L-shaped structure in plan view, the short side is connected with the discharge port of the linear conveying mechanism, and a twisting roller 302 is installed laterally on the short side, specifically, the twisting roller 302 is installed on the side opening of the short side and is in contact with the carbon brush or brush braid to push the carbon brush to continue advancing. The roller motor 301 is fixed to the short side through a motor mounting bracket 303. Further, the end of the short side is also provided with a cutoff mechanism, including a cutoff cylinder 304 and a cutoff cylinder mounting plate 305, and the connection of the long side of the detection track 3 is designed as an open design, when the cutoff cylinder 304 receives a signal and extends, it can block the carbon brush from moving along the track. Further, the long side of the detection track 3 is uniformly provided with six brush positions, among which the first brush position 313 corresponds to the cutoff position, followed by the second brush position 314, the third brush position 315, the fourth brush position 316, the fifth brush position 317, and the last sixth brush position belongs to the position of the end feeding, which is specifically set as a material taking position, and a laser position sensor 311 is fixed on the lateral side through a sensor bracket 310, which is used to detect whether there is material in the sixth brush position. Further, the detection track 3 is also provided with detection electrodes 307 at the position corresponding to the second brush position 314, as shown, the upper and lower electrode sheets are horizontally arranged and fixed to the lateral side of the long side through a nylon bracket 308, the upper electrode sheet of the detection electrode 307 is in contact with the carbon brush braid, and the lower electrode sheet is in contact with the rubber tube sleeved on the brush braid, which is used to detect whether the carbon brush tube is in place.

[0038] The moving slide 4 is a two-dimensional moving platform, the main body is fixed to the workbench 1 through two slide mounting seats 401, the longitudinal execution unit is a longitudinal cylinder 402, which is fixedly connected with the bottom plate, and the piston rod end is fixedly connected with a longitudinal sliding plate 403. The longitudinal sliding plate 403 is fixedly installed with a transverse cylinder 404, the piston rod end is fixedly connected with a transverse sliding plate 405 through an adapter, and the transverse sliding plate 405 serves as the moving end of the moving slide 4. Preferably, a limit stop plate 406 is arranged at the limit position of the transverse sliding plate 405, the limit stop plate 406 is fixedly connected with the longitudinal sliding plate 403 and is provided with a limit screw 408 and a buffer 407. The transverse sliding plate 405 is provided with a fork at a position corresponding to each brush position of the detection track 3, it is necessary to point out that in this embodiment, five forks are uniformly distributed on the side of the transverse sliding plate facing the brush positions of the detection track 3, and the interval is consistent with the interval of the brush positions, and they are sequentially a first fork 410, a second fork 411, a third fork 412, a fourth fork 413 and a fifth fork 414. The first fork 410 is provided with an electric contact 409.

[0039] The main function of the movable slide 4 is to move the longitudinal cylinder 402 forward and the transverse cylinder 404 backward, waiting to receive carbon brushes. When the carbon brush at the first brush position 313 is in place, the electrical contact 409 is turned on, stopping the forward position of the stop cylinder 304 and preventing the carbon brush from moving forward. The transverse cylinder 404 moves the shift fork to move the carbon brush at the first brush position 313 to the second brush position 314. At the same time, the carbon brushes at the second to fifth brush positions are moved sequentially from the second to fifth shift forks to the third to sixth brush positions. After they are in place, the longitudinal cylinder 402 is in the backward position, the transverse cylinder 404 is retracted, and the longitudinal cylinder 402 moves forward again, ready to enter the next cycle.

[0040] like Figure 5 As shown, the main body of the braid shaping mechanism 5 is a lifting mechanism, and a rotary mechanism is installed at the movable end. The movable end of the rotary mechanism is provided with a first clamping mechanism. Preferably, the main body of the lifting mechanism is a lifting cylinder 503, which is connected to the lifting mechanism mounting seat 501 via a longitudinal cylinder mounting plate 502. The piston rod of the lifting cylinder 503 is equipped with a rotary mechanism, which includes a first rack cylinder 507, a rack 506, a rack guide seat 505, and a first gear 508. The rack guide seat 505 is a horizontally open square groove, in which the rack 506 is embedded and slidably connected. The top surface of the rack guide seat 505 is fixedly connected to the piston rod, and a slider is installed on the back. Correspondingly, a linear guide rail 504 is installed at the corresponding position on the lifting mechanism mounting seat 501 to form a sliding mechanism. A first rack cylinder 507 is mounted laterally on the rack guide seat 505. The piston rod end of the first rack cylinder 507 is fixedly connected to the rack 506, which drives the rack 506 to slide along the slot of the rack guide seat 505. A first bearing 509 is also provided on the front side of the rack guide seat 506. A first gear 508 is located above the first bearing 509 and is coaxially connected to a first clamping mechanism via a rotating shaft 510. In this embodiment, the first clamping mechanism is a vertically arranged gripper cylinder 511, and the gripper finger 512 at the end is used to clamp the end of the brush braid. The first gear 508 meshes with the rack 507 and rotates as the first rack cylinder 507 moves. The main function of the brush braid shaping mechanism 5 is to complete the rotation and upward pulling action of the brush braid at the fourth brush position, straightening the line. When the carbon brush at the fourth brush position 316 is in place, the lifting cylinder 503 lowers, the gripper finger 512 of the clamping cylinder 511 clamps the brush head, the first rack cylinder 507 moves forward, and at the same time the lifting cylinder 503 moves up, driving it to rotate and rise. After it reaches the position, the first rack cylinder 507 retracts to the rear position.

Two parallel screw baffles 604 are arranged on both sides of the screw track 607 with a spacing in the middle, and a screw limiting baffle 605 is arranged at the end of the screw track 607 for blocking the screw from being pushed out, thereby forming a screw taking position. The surface of the screw baffle 604 is further provided with two elastic blocks 606 to prevent the robot 7 from directly colliding with the baffle when taking the screw, thereby playing a buffering role. The screw stop cylinder 603 and the push rod cylinder 602 are connected through a cylinder mounting plate 608 at the front end opening of the screw track 607. The movable end of the screw stop cylinder 603 is provided with a block or a baffle for intercepting the screw, and the push rod cylinder 602 is used for pushing the screw to move along the track.
