Referring to fig. 1 and 2, the present application provides a commutator mounting apparatus. The commutator installation equipment comprises a frame 1, a turntable assembly 2 rotatably arranged on the frame 1, and a rotor feeding device 3, a detection turnover device 4, a commutator assembly device 5, a rotor blanking device 6 and a circulating receiving device 7 which are sequentially arranged on the frame 1 around the turntable assembly 2; the turntable assembly 2 comprises a turntable main body 21 and a plurality of profiling 22 which are arranged on the periphery side of the turntable main body 21 and are used for magnetically attracting the rotor; the rotating disc assembly 2 rotates to drive the profiling 22 to be sequentially abutted against the rotor feeding device 3, the detection overturning device 4, the commutator assembling device 5 and the rotor discharging device 6; the circulating receiving device 7 is arranged opposite to the rotor blanking device 6 and is used for circulating conveying of the jig.

According to the technical scheme, after the rotor feeding device 3 is fed onto the profiling 22, the rotor feeding device can move to the corresponding station of each device along with the turntable main body 21, and the assembling operation of the commutator is realized by matching each device with the profiling 22, so that the automatic degree is high, and the commutator can be efficiently and accurately installed.

Referring to fig. 8, in some embodiments, the rotor feeding device 3 includes a rotor feeding conveyor line 31 and a rotor feeding grabbing module 32; the rotor feeding conveying line 31 comprises two parallel conveying belts 311 which are synchronously conveyed, a guiding and limiting mechanism 312 is arranged along the conveying direction of the two conveying belts 311, and a rotor is supported between the two conveying belts 311 and conveyed along the guiding and limiting mechanism 312; the rotor material loading snatchs the module 32 butt joint and is arranged between rotor material loading transfer chain 31 and profiling 22 for snatch the rotor on the rotor material loading transfer chain 31 and shift to the profiling 22.

In this embodiment, the rotor feeding conveyor line 31 is abutted with a processing device, for example, a rotor feeding device, and the rotor feeding device transfers the rotor from the tray to the rotor feeding conveyor line 31 for conveying. The rotor feeding conveying line 31 adopts the conveying belts 311 with synchronous action, and is limited by the guiding limiting mechanism 312 on the rotor conveyed on the rotor feeding conveying line 31, when the rotor is placed on the rotor feeding conveying line 31, the rotor is only required to be aligned between the two conveying belts 311, so that the structure design is relatively simple, and the rotor is easy to be positioned and placed on the rotor feeding conveying line 31.

And then after the rotor is conveyed in place on the rotor feeding conveyor line 31, the rotor feeding grabbing module 32 grabs the rotor and transfers the rotor to the profiling 22. The rotor loading grabbing module 32 generally includes a grabbing robot and a robot moving module for transferring the robot, which are conventional design means in the art and will not be described herein. Moreover, it should be noted that, in the technical scheme of the present application, other grabbing and transferring devices related to the rotor are all similar structures, such as the rotor blanking device 6, and are not described in detail in the technical scheme of the present application.

In some embodiments, the master 22 includes a master base 221 and a magnet 222; the die holder 221 is mounted on the peripheral side of the rotor body, and a placement position for placing the rotor is formed on the die holder 221, and the placement position supports the rotor from the bottom; the magnetic attraction piece 222 is correspondingly arranged in the die holder 221 and is used for magnetically attracting the rotor on the fixed position.

In this embodiment, when the rotor is placed on the die holder 221, the die holder 221 can support the rotor from the bottom, and can fix the rotor through the magnetic attraction piece 222, so that the rotor can be abutted from the bottom in the process of pressing down the rotor when the commutator is installed, and the assembly of the commutator is assisted.

The magnetic attraction pieces 222 are disposed on the master base 221 beside the placement position, the placement position is a semi-arc leaning slot, a plurality of magnetic attraction pieces 222 are disposed, and the magnetic attraction pieces 222 may be magnets.

Further, after the rotor is transferred and placed on the profiling 22, the turntable body 21 rotates to drive the profiling 22 to move to the detection turnover device 4. Referring to fig. 1, the detecting and turning device 4 includes a visual detecting mechanism 42 and a turning reversing assembly 41; the visual detection mechanism 42 is used for detecting whether the rotor on the master 22 is placed in a predetermined direction; the turnover reversing assembly 41 is disposed below the visual detection mechanism 42 and is disposed opposite to the master 22, and the turnover reversing assembly 41 is configured to adjust the direction of the rotor on the master 22 when the visual detection member detects that the rotor is placed in a non-predetermined direction.

In this embodiment, the visual inspection mechanism 42 may be a CCD visual inspection machine. It will be appreciated that the side of the rotor on which the commutator is mounted is provided with a clamping hole adapted to the commutator jaw, and that when the clamping hole is not provided on the upward side of the rotor on the master 22, the direction of placement of the rotor on the master 22 is considered to be the opposite direction, and at this time, the assembly of the commutator in the next station cannot be performed. Therefore, the purpose of the visual detection mechanism 42 is to determine whether the rotor is correctly placed on the master 22 by detecting whether the rotor has the hole, if so, the rotor continues to be transferred to the next station along with the master 22 for assembling the commutator, and if not, the reversing assembly 41 starts to act to reverse the rotor at 180 and then continues to be transferred to the next station.

The turnover reversing assembly 41 can rotate 180 degrees relative to the rotor feeding grabbing module 32, and can drive the rotor to reverse.

Further, the rotor is transferred to the commutator assembly apparatus 5 along with the cam 22 for commutator assembly.

Referring to fig. 1, in some embodiments, the commutator assembly apparatus 5 includes a commutator preassembling apparatus 51 and a commutator pressing and positioning apparatus 52, which respectively implement pre-pressing and finish-pressing of the commutator; in this way, the mounting of the commutator is divided into the two steps, and the accuracy of the mounting of the commutator is ensured.

Referring to fig. 3 and 4, the commutator preassembling device 51 includes a vibration feeding mechanism 53 and a material taking preassembling mechanism 54 abutted to the vibration feeding mechanism 53, wherein the vibration feeding mechanism 53 is used for providing orderly-conveyed commutators, and the material taking preassembling mechanism 54 is used for grabbing the commutators and prepressing the commutators onto a rotor.

Specifically, the vibration feeding mechanism 53 includes a vibration plate mechanism 531 and a direct vibration mechanism 532; the direct vibration mechanism 532 is connected to the output end of the vibration disc mechanism 531, and screening and conveying of the commutator are achieved through cooperation between the vibration disc mechanism 531 and the direct vibration mechanism 532. The conveyance path of the oscillating mechanism 532 is a straight-through type, which is understood to mean that the commutator can be conveyed on the oscillating mechanism 532 along its conveyance path until it is disengaged. Therefore, a dam mechanism 533 is provided at the output end of the direct vibration mechanism 532, and the dam mechanism 533 is used for positioning the commutator conveyed on the direct vibration mechanism 532, thereby preventing the commutator from being separated.

Wherein the feed path of the direct vibratory mechanism 532 is designed to be straight through for the purpose of cooperating with the take-off pre-load mechanism 54 to facilitate transfer of the diverter. The transfer process comprises the following steps: the straight vibration mechanism 532 conveys the diverter until it is blocked by the dam mechanism 533, the take-off pre-load mechanism 54 grabs the positioned rotor and continues to move along the conveying path of the straight vibration mechanism 532, which pushes the dam mechanism 533 to open the conveying path of the blocked straight vibration mechanism 532 until the take-off pre-load mechanism 54 grabs the diverter and breaks away along the conveying path.

To achieve the relevant action of the striker mechanism 533, the striker mechanism 533 is movably disposed. Referring to fig. 4, in some embodiments, the striker mechanism 533 includes a stopper 5331 and a telescoping spring 5332; one end of the stop 5331 is transversely arranged on the conveying path of the direct vibration mechanism 532, and the other end of the stop 5331 is rotatably arranged; one end of the telescopic spring 5332 is connected to the other end of the stop block 5331, and the other end of the telescopic spring is fixedly arranged; when the stopper 5331 rotates in the conveying direction of the direct vibration mechanism 532, the expansion spring 5332 deforms.

Further, when the take-out pre-loading mechanism 54 grips the positioned rotor and moves along the conveying path of the vertical vibration mechanism 532, the stopper 5331 is pushed to rotate around the other end thereof, so that the conveying path of the blocked vertical vibration mechanism 532 is opened. The expansion spring 5332 is deformed, and the deformation is usually stretched, so that after the commutator is transferred, the rotating stop 5331 returns to the original position under the restoring force of the expansion spring 5332, and the next commutator conveyed by the direct vibration mechanism 532 is continuously blocked. In order to ensure that the stopper 5331 returns to the same position each time, to achieve positioning accuracy of the commutator, a stop structure may be provided for the return action of the stopper 5331, and the stop structure may be a stop block (not shown in the drawings) provided on one side of the corresponding stopper 5331.

Referring to fig. 3, in some embodiments, take-off pre-load mechanism 54 includes a movement module 541, a take-off assembly 542, and a guide sleeve assembly 545; the moving module 541 is configured to drive the material taking assembly 542 and the guide sleeve assembly 545 to move between the vibratory feeding mechanism 53 and the profile 22; the material taking assembly 542 is connected to the moving module 541, and the material taking assembly 542 includes a material taking needle 543 and a material needle driving member 544 for driving the material taking needle 543 to move in a vertical direction; the guide sleeve assembly 545 is connected to the moving module 541, the guide sleeve assembly 545 comprises a guide sleeve 546, a guide sleeve mounting plate 547 and a guide sleeve driving piece 548, the guide sleeve 546 is connected to the guide sleeve driving piece 548 through the guide sleeve mounting plate 547, and the guide sleeve driving piece 548 is used for driving the guide sleeve 546 to move in the vertical direction; the guide sleeve 546 is sleeved on the material taking needle 543.

In this embodiment, the picking needle 543 is used to complete the grabbing of the commutator positioned on the direct vibration mechanism 532. It can be understood that when the commutator is assembled on the rotor, the middle part of the commutator is provided with an assembly hole assembled with the rotating shaft in the rotor, and the grabbing process of the commutator on the direct vibration mechanism 532 in this embodiment is as follows: the moving module 541 drives the material taking assembly 542 to move to the upper part of the positioned commutator on the direct vibration mechanism 532, and the material taking needle 543 is opposite to the assembly hole of the commutator; then, under the action of the needle driving piece 544, the needle 543 moves downwards to be inserted into the assembling hole of the commutator, and the diameter of the needle 543 is slightly larger than that of the assembling hole, so that the needle 543 is relatively tight to the assembling hole of the commutator, and the commutator cannot fall off relative to the needle 543.

Then, the moving module 541 acts to drive the commutator to move and abut against the rotating shaft of the rotor on the die 22, and the commutator is further preassembled on the rotor under the cooperation of the material taking needle 543 and the guide sleeve assembly 545. The process comprises the following steps: the guide sleeve driving piece 548 drives the guide sleeve 546 to move downwards, so that the commutator on the material taking needle 543 can be pushed to move along the material taking needle 543, and when the material taking needle 543 is abutted against the rotating shaft of the rotor, the commutator moves and transits to the rotating shaft of the rotor, and preassembling of the commutator is completed.

Further, the master 22 moves to drive the preloaded commutator to move to the commutator pressing and positioning device 52 for fine press assembly of the commutator. The commutator depression positioning device 52 is disposed adjacent to the commutator preassembling device 51.

Referring to fig. 5-7, in some embodiments, the commutator pressing and locating device 52 includes a mounting seat 55, and a locating mechanism 56 and a rotating pressing mechanism 57 disposed on the mounting seat 55, where the locating mechanism 56 is disposed parallel to the master 22 and is used to cooperate with the master 22 to fix the rotor; the rotary pressing mechanism 57 is used for driving the commutator pre-pressed on the rotor to rotationally press down, so that assembly between the commutator and the rotor is completed.

In this embodiment, the adopted process of coining the commutator is that the commutator is driven to rotate while the commutator is pressed down, and in the rotating and pressing process, if the claw on the commutator rotates to the position above the corresponding clamping hole on the rotor, the claw can be clamped into the clamping hole under the pressing acting force, so that the coining assembly of the commutator is completed. Therefore, the rotor is fixed by the positioning mechanism 56, and the rotary pressing mechanism 57 drives the commutator to rotationally press down so as to achieve the action of the commutator relative to the rotor.

Referring to fig. 7, in some embodiments, positioning mechanism 56 includes a positioning block 561 and a positioning drive 562; the positioning driving member 562 is connected to the mounting base 55, and an output end of the positioning driving member 562 is connected to the positioning block 561, where the positioning driving member 562 is used to drive the positioning block 561 to approach or separate from the rotor on the master 22.

The positioning block 561 is provided with a fitting groove formed by fitting the periphery of the rotor, so that the fixing effect on the rotor is better when the positioning block is matched with the master 22.

In some embodiments, the mount 55 is provided with a push-down slide rail; the rotary pressing mechanism 57 includes a pressing-down driving member 571 and a rotary pressing-down module; the pressing-down driving member 571 is mounted on the mounting seat 55; the rotary pressing module is in sliding connection with the pressing sliding rail and is connected with the pressing driving piece 571 so as to move in the vertical direction along the pressing sliding rail under the driving of the pressing driving piece 571, and the rotary pressing module is used for driving the commutator to rotationally press. In this way, the rotary pressing module is driven by the pressing driving member 571 to move to a predetermined position in advance, and when the rotary pressing module is at the predetermined position, the rotary pressing module can provide a continuous pressing force for the commutator based on its own structural design, and further complete the rotary pressing action for the commutator when rotating.

Referring to fig. 8 and 7, in some embodiments, the rotary press-down module includes a rotary drive member 572, a press-down sleeve 573, a press-down head 574, and an elastic member (not shown in the figures); the rotary driving member 572 is mounted above the mount 55; the hold down sleeve 573 is connected to the output end of the rotary drive member 572; the lower pressure head 574 is partially sleeved in the lower pressure sleeve 573 and can move along the lower pressure sleeve 573 in the vertical direction, an anti-rotation structure is arranged between the lower pressure head 574 and the lower pressure sleeve 573, and the anti-rotation structure is used for the lower pressure head 574 to rotate along with the lower pressure sleeve 573; the elastic piece is arranged between the pressing sleeve 573 and the pressing head 574 and is used for providing the acting force of the pressing movement of the pressing head 574; wherein, still be provided with the anticreep structure between lower pressure head 574 and the sleeve 573 that pushes down for prevent to push down pressure head 574 and break away from the sleeve 573, this anticreep structure can be the anticreep step that sets up between pressure head main part 5741 and the sleeve 573 that pushes down.

In this embodiment, the lower ram 574 is the component in contact with the commutator. Wherein the continuous depression driving force is provided by an elastic member, which is a compression spring, which is abutted between the top of the lower ram 574 and the top inner wall of the depression sleeve 573. The rotation is driven by the rotation driving member 572 to rotate the pressing sleeve 573 and thus the pressing head 574.

Specifically, referring to fig. 7, lower ram 574 includes ram body 5741 and abutment bar 5742; the lower end of the ram body 5741 extends out of the hold-down sleeve 573; the pushing rods 5742 extend downwards from the end part of the lower end of the pressure head main body 5741 and are used for being inserted between adjacent lugs on the periphery side of the commutator, and the number of the pushing rods 5742 is opposite to that of the lugs on the periphery side of the commutator; when the lower ram 574 rotates, the abutting rod 5742 abuts against the bump to drive the commutator to rotate.

As can be appreciated, when the rotary drive member 572 drives the lower ram 574 to rotate, the abutment lever 5742 rotates, and the abutment lever 5742 further abuts against the boss provided on the peripheral side of the commutator, thereby pushing the commutator to rotate.

The principle is as follows: when the commutator is coined in place, as the clamping claw on the commutator is clamped into the clamping hole of the rotor, the commutator can downwards move for a certain distance based on the height drop, and then the test plate 5752 is driven to move, and the sensing detection mechanism 5753 detects the movement of the test plate 5752.

More specifically, the sensing detection mechanism 5753 is an infrared sensor, and the test board 5752 is provided with a light avoiding hole through which infrared light emitted by the infrared sensor passes. When the commutator is coined in place, the light dodging holes on the test plate 5752 can just pass through the infrared optical fibers of the infrared sensor, so that the detection purpose is achieved.

After finishing the commutator finish-pressing assembly, the rotor on the profiling 22 is transferred to the circulating receiving device 7 by the rotor blanking device 6 for blanking and conveying, and the rotor blanking device 6 is not repeated.
