[0040] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0041] against Figure 1 Automated assembly processes, such as Figure 2 and Figure 3 As shown, this utility model provides an automatic feeding and assembly device for double-gear motors, including a motor conveying mechanism, a gear conveying mechanism 2, and a transfer assembly mechanism 3. The motor conveying mechanism is used to place several motor components 10 one by one into the motor placement position 1, and to make the gear shaft on the motor component 10 vertically upward. The gear conveying mechanism 2 is used to convey several double-gear workpieces 20 one by one to the gear receiving position, which is located on one side of the motor placement position 1. The transfer assembly mechanism 3 is used to transfer the double-gear workpieces 20 one by one from the gear receiving position to the motor placement position 1, and to fit the double-gear workpieces 20 onto the gear shaft, and to rotate the double-gear workpieces 20 to a set angle.

[0042] Thus, by integrating automated conveying, precise positioning, and intelligent assembly, the assembly process is fully automated, effectively solving the problems of low efficiency, high labor intensity, and insufficient positioning accuracy in manual assembly. In particular, it ensures the rapid and accurate alignment and fitting of the double gear workpiece 20 and the gear shaft of the motor assembly 10, and ensures that the double gear is installed in place by controlling the assembly angle by rotation, which significantly improves assembly efficiency and product qualification rate.

[0043] In at least one embodiment, the transfer assembly mechanism 3 includes a three-axis drive module and a rotary gripper cylinder 31. The rotary gripper cylinder 31 is disposed at the output end of the three-axis drive module. The rotary gripper cylinder 31 is used to clamp the double gear workpiece 20 and drive the double gear workpiece 20 to rotate axially. The three-axis drive module is used to drive the rotary gripper cylinder 31 to move in the X, Y and Z directions relative to the motor placement position 1.

[0044] The three-axis drive module ensures that the double gear workpiece 20 is accurately moved in space to the gear shaft of the motor assembly 10, while the rotary gripper cylinder 31 is responsible for gripping the double gear workpiece 20 and can drive the double gear workpiece 20 to rotate to a preset assembly angle, ensuring that the double gear workpiece 20 is accurately meshed with the power gear or other gears of the motor assembly 10.

[0045] The rotary gripper cylinder 31 is existing technology and has clamping and rotation functions, which can meet the requirements of clamping and rotating the double gear workpiece 20 here.

[0046] The horizontal straight line from the gear receiving position to the motor placement position 1 is defined as the X direction, the vertical direction of the motor placement position 1 is defined as the Z direction, and the direction perpendicular to the X and Z directions is defined as the Y direction. The three-axis drive module includes a transfer frame 32 that can move along the X direction, a translation plate 33 that can move along the Y direction is provided on the transfer frame 32, a lifting plate 34 that can move along the Z direction is provided on the translation plate 33, and a rotary gripper cylinder 31 is mounted on the lifting plate 34.

[0047] The rotary gripper cylinder 31 moves along the X direction via the action of the transfer frame 32, the rotary gripper moves along the Y direction via the action of the translation plate 33, and the rotary gripper cylinder 31 moves along the Z direction via the action of the lifting plate 34. This ensures the repeatability and positioning accuracy of the rotary gripper cylinder 31 during the transfer of the double-gear workpiece 20, and enables a wide range of precise movements within a limited space.

[0048] Furthermore, X-axis guide rails 35 are provided on both sides of the gear receiving position, and the transfer frame 32 is slidably mounted on the X-axis guide rails 35 and driven by the first transfer cylinder; Y-axis guide rails 36 are provided on the transfer frame 32, and the translation plate 33 is slidably mounted on the Y-axis guide rails 36 and driven by the second transfer cylinder 38; Z-axis guide rails 37 are provided on the translation plate 33, and the lifting plate 34 is slidably mounted on the Z-axis guide rails 37 and driven by the third transfer cylinder 39.

[0049] Furthermore, position sensors 4 for monitoring the piston stroke of each cylinder are respectively installed on the first transfer cylinder, the second transfer cylinder 38 and the third transfer cylinder 39.

[0050] Multiple transfer cylinders and guide rails are used to ensure the movement accuracy in the X, Y, and Z directions. Each transfer cylinder is equipped with a position sensor 4 (such as a magnetic switch or displacement sensor) to provide real-time feedback on the output stroke of the corresponding transfer cylinder. This ensures that the rotary gripper cylinder 31 moves accurately when gripping and assembling the double gear workpiece 20, effectively avoiding problems such as the double gear workpiece 20 being missed, accidentally falling, being improperly assembled, or being over-assembled.

[0051] To further ensure the assembly effect, the transfer frame 32 is equipped with positioning sensors 5 on both sides of the motor placement position 1. The positioning sensors 5 on both sides are used to detect whether the double gear workpiece 20 is installed in place on the gear shaft, so as to effectively identify defective products such as missing parts, tilting, or incomplete installation. Incomplete installation here mainly refers to the gears not meshing properly.

[0052] In at least one embodiment, the gear conveying mechanism 2 includes a gear vibratory plate 21 and a lifting assembly. The gear vibratory plate 21 holds a plurality of double-gear workpieces 20. The output end of the gear vibratory plate 21 is provided with a conveying channel 22, and the double-gear workpieces 20 are output one by one along the conveying channel 22. The end of the conveying channel 22 is provided with a stop block 23, and the stop block 23 is provided with a limit groove. The limit groove is used to position the double-gear workpieces 20 located at the end of the conveying channel 22, and the gear receiving position is located directly above the limit groove. The lifting assembly is used to lift the double-gear workpieces 20 in the limit groove to the gear receiving position.

[0053] The gear vibratory plate 21 can realize the automatic sorting and directional conveying of a large number of double gear workpieces 20, improving the feeding efficiency and automation level; the lifting component will steadily lift the horizontally conveyed double gear workpieces 20 one by one to the set height (i.e., the gear receiving position), making it easier for the transfer assembly mechanism 3 to grab them.

[0054] Furthermore, the lifting assembly includes a lifting cylinder 24 disposed below the stop block 23. The output rod of the lifting cylinder 24 extends into the limiting groove, and the end of the output rod of the lifting cylinder 24 is provided with a positioning block 25 for supporting and positioning the double gear workpiece 20.

[0055] By driving the positioning block 25 on the output rod through the lifting cylinder 24, the double gear workpiece 20 can be gently lifted from the limiting groove. The design of the positioning block 25 can ensure that the double gear workpiece 20 maintains the correct posture and center position during the lifting process, preventing it from tipping over or shifting, thus laying a good foundation for subsequent gripping and assembly.

[0056] In summary, this automatic feeding and assembly device for double-gear motors constructs a highly efficient and precise automated assembly unit through the coordinated action of multiple mechanisms. In particular, the transfer assembly mechanism 3 achieves precise spatial positioning with its three-axis drive module. Combined with the application of the rotary gripper cylinder 31 and the positioning sensor 5, it ensures precise controllability throughout the entire process of double-gear gripping, angle rotation, and installation, guaranteeing positioning accuracy and assembly quality. This significantly improves production efficiency and product consistency, reduces labor costs and operational difficulty, and provides reliable technical support for the design of automated production lines.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
