Several product positioning fixtures 21 are assembled on the circular conveyor track 2. The motor feeding assembly 5, the shaft plate feeding assembly, and the receiving assembly 9 have similar structures, the difference being the material gripped by the actuator.

[0030] An oiling assembly 3 is provided between the small gear assembly 7 and the idler gear assembly 6, as well as between the idler gear assembly 6 and the secondary gear assembly 8; and an oil hole venting assembly is provided after the oiling assembly 3.

[0031] In this embodiment, an automated motor assembly device also includes an external controller for controlling the start and stop of each component in the device. The circular conveyor track 2 can be positioned and stopped as needed, suspending the product positioning fixture under the designated component for assembly operations.

[0032] The specific assembly method of this invention is as follows: The circular conveyor track 2 is opened, driving the product positioning fixture 21 to rotate between the components. The product positioning fixture 21 first enters the motor loading position, where the motor loading assembly removes the motor from the centralized incoming material and transports it to the product positioning fixture 21. Then, it enters the shaft plate loading position, where the shaft plate loading assembly assembles the motor shaft plate onto the motor. Next, the shaft plate screw fastening assembly 4 screws the motor shaft plate onto the motor. The product positioning fixture 21 rotates to a position below the small gear assembly assembly 7, where the small gear is assembled onto the motor main shaft. Then, the first oiling is performed, followed by the idler gear spinning assembly position, where the idler gear spinning assembly 6 performs idler gear spinning assembly. The oiling operation is performed again, followed by the secondary gear spinning assembly position, where the secondary gear spinning assembly 8 spins the three secondary gears.

[0033] In this embodiment, the motor feeding assembly 5 includes a storage rack 52, a storage lifting assembly, a tray displacement assembly, a feeding X-transfer assembly, a feeding Y-transfer assembly, and a feeding transfer assembly.

Furthermore, the storage lifting assembly is connected to a lifting fixing frame 5. 5 is mounted below the equipment platform and includes a material storage lifting motor 551, a lifting reducer 552, a lifting connecting block 553, and a lifting screw 554.

The lifting motor 551 is mounted on the lifting fixed frame 55, and its output end drives the lifting reducer 552. The lifting connecting block 553 is mounted on the lifting screw 554, and the other end is fixed to the material storage rack body 52. ​​Furthermore, a material storage tripod 521 is provided at the bottom of the material storage rack body 52, and a material tray 522 is installed inside. The material storage tripod 521 is slidably connected to the rear end face of the lifting fixed frame 55, and the material storage tripod 521 is fixedly connected to the lifting connecting block 553.

[0034] The material lifting motor 551 provides the lifting power, driving the lifting screw 554 via the lifting reducer 552, which in turn drives the lifting connecting block 553. By presetting a specific rotation cycle for the lifting motor 551, the lifting connecting block 553 is driven to a predetermined position, which in turn drives the material storage rack 52. The up-and-down movement of the material storage rack 52, in conjunction with the material tray displacement component, allows the material tray 522 to be removed from the material storage rack 52 and returned to the material storage rack 522 after loading.

[0035] Furthermore, the tray displacement assembly includes a tray linear module 561 and a tray insert plate 562; the tray linear module 561 is mounted on the equipment table via several displacement mounting seats 563, and the tray insert plate 562 is assembled at the output end of the tray linear module 561.

[0036] The material tray linear module 561 drives the material tray insert plate 562 to reciprocate; it can take out and store the material tray 522 from the storage rack 52. The actuator of the material tray linear module 561 drives the material tray insert plate 562 at a specific distance, which can feed several rows of motors in the material tray 52 to the bottom of the loading and conveying component, so that the loading and conveying component can quickly grab them.

[0038] The X-transfer linear module 511 is a linear module driven by an encoder motor. It can be adjusted as needed to suspend the X-transfer lowering module 512 at the position of the motor in the material tray 522, so as to cooperate with the X-transfer pneumatic gripper 515 to grasp the material of the motor. Then, with the cooperation of the X-transfer linear module 511, the material of the motor is transported along the X axis, and the motor is placed on the loading Y-transfer assembly to wait for the next transfer loading.

[0039] Furthermore, the loading Y-transfer assembly is a Y-transfer linear module 53, and the execution end of the Y-transfer linear module 53 is equipped with a Y-transfer pneumatic gripper 532 through a Y-transfer seat block 531.

By adjusting the hovering position of the Y-transfer block 531, it can receive the motor brought by the loading X-transfer assembly and clamp and fix it by the Y-transfer pneumatic gripper 532, and then transfer it to the designated position to wait for the loading transfer assembly to transfer it.

[0041] Furthermore, the feeding and transfer assembly is mounted on the equipment table via a transfer frame 54, and includes a reciprocating module 541 and a transfer pneumatic gripper 542.

[0042] The feeding and transfer assembly removes the motor Y-type conveying assembly and transports the motor to the positioning fixture on the turntable via the reciprocating module 541, achieving rapid reciprocating feeding and stably and quickly transferring the material to the turntable.

[0045] In the shaft plate screw fastening assembly 4, the screw fastening displacement module 41 is a linear module that can hover the screw fastening lifting module 42 at multiple points, ensuring that the screw fastening lifting module 42 can reciprocate between the screw box 46 and the screw fastening auxiliary cylinder 44.
