[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] Please refer to the following: Figures 1-2 An automated installation device for motor rotors is designed to automate the installation of motor stators and rotors, thereby improving production efficiency. The device has a compact overall structure, with all components working collaboratively to complete the assembly of the stator and rotor.

[0028] The equipment mainly includes a frame 1. On one side of the frame 1, a stator conveyor line 2, a rotor conveyor line 3, and a recycling conveyor line 9 are arranged in sequence. The stator conveyor line 2 is used to convey the stator tray 4 loaded with stators, the rotor conveyor line 3 is responsible for conveying the rotor tray 5 loaded with rotors, and the recycling conveyor line 9 is used to recycle the rotor tray 5 that has become empty after the rotor has been removed.

[0029] The frame 1 serves as the supporting structure for the entire equipment, providing a stable mounting base for other components. A YZ-axis drive mechanism 6 is mounted on the frame 1; this mechanism is a key component for achieving precise movement of the stator in space. The YZ-axis drive mechanism 6 includes a Y-axis linear motor 61 fixed to the frame 1. The output shaft of the Y-axis linear motor 61 is fixedly connected to a Z-axis cylinder 62, and the output end of the Z-axis cylinder 62 is fixedly connected to a fixing plate 7. Through the coordinated action of the Y-axis linear motor 61 and the Z-axis cylinder 62, the fixing plate 7 can achieve precise movement in the Y and Z axis directions.

[0030] A gripping part 8 is fixedly installed on the bottom of the fixing plate 7. The gripping part 8 can be a commonly used mechanical gripper or an electromagnet. When the gripping part 8 is an electromagnet, it will generate magnetism when energized, thereby attracting the iron rotor.

[0031] It should be noted that both the stator conveyor line 2 and the rotor tray 5 can be controlled to reach their designated positions by setting corresponding sensors. A positioning camera can be used to photograph and position the gripped rotor, enabling the YZ axis drive mechanism 6 to drive the gripping unit 8 to precisely assemble the rotor. These are all commonly used technologies in the prior art, and will not be elaborated upon here.

[0032] The rotor is initially placed on the rotor tray 5, which has multiple rotor mounting slots 51. The rotor is placed within these slots. Driven by the YZ-axis drive mechanism 6, the gripping part 8 moves above the rotor tray 5, adsorbs the rotor, and then moves it above the stator tray 4, gradually inserting the rotor into the stator mounting slots 41 on the stator tray 4, thus completing the assembly of the stator and rotor. After assembly, the YZ-axis drive mechanism 6 continues to reciprocate to perform the assembly of the next set of stator and rotor.

[0033] The specific structure of the stator conveyor line 2 is as follows: It includes a stator conveyor frame 21, with a stator drive conveyor roller 22 and a stator driven conveyor roller 23 rotatably connected to both ends of the stator conveyor frame 21. The stator drive conveyor roller 22 and the stator driven conveyor roller 23 are connected by two stator conveyor belts 24, and the bottom of the stator tray 4 is placed on these two stator conveyor belts 24. A stator conveyor motor 25 is also installed on the stator conveyor frame 21, and the output shaft of the stator conveyor motor 25 is fixedly connected to the end of the stator drive conveyor roller 22. When the stator conveyor motor 25 starts, it drives the stator drive conveyor roller 22 to rotate, which in turn drives the stator driven conveyor roller 23 to rotate through the stator conveyor belts 24, thus realizing the conveying of the stator tray 4 on the stator conveyor line 2.

[0034] The structure of the rotor conveyor line 3 is similar to that of the stator conveyor line 2: it includes a rotor conveyor frame 31, with a rotor active conveyor roller 32 and a rotor driven conveyor roller 33 rotatably connected to both ends of the rotor conveyor frame 31. The rotor active conveyor roller 32 and the rotor driven conveyor roller 33 are connected by a rotor conveyor belt 34, and the bottom of the rotor tray 5 is placed on the rotor conveyor belt 34. A rotor conveyor motor 35 is mounted on the rotor conveyor frame 31, and the output shaft of the rotor conveyor motor 35 is fixedly connected to the end of the rotor active conveyor roller 32. After the rotor conveyor motor 35 starts, it drives the rotor active conveyor roller 32 to rotate, which in turn drives the rotor driven conveyor roller 33 to rotate through the rotor conveyor belt 34, thus realizing the conveying of the rotor tray 5 on the rotor conveyor line 3. The rotor is installed in the rotor mounting slots 51 on the rotor tray 5, and these rotor mounting slots 51 are distributed in a strip array.

[0035] On the rotor conveyor line 3, a pushing device 10 is also installed to push the empty rotor tray 5 onto the recycling conveyor line 9. The pushing device 10 includes a cylinder 101 fixed on the rotor conveyor frame 31, and a push plate 102 is fixedly connected to the output end of the cylinder 101. A baffle 103 is also fixed on the rotor conveyor frame 31, and a notch 104 is provided on the rotor conveyor frame 31 directly opposite the push plate 102. When all the rotors on the rotor tray 5 are removed and it becomes empty, the cylinder 101 will be activated, pushing the push plate 102 forward, pushing the empty rotor tray 5 from the rotor conveyor line 3 across the notch 104 and onto the recycling conveyor line 9 for recycling by workers.

[0036] In addition, the equipment is equipped with a manual transfer and installation assembly a, which is used for manually assembling the rotor with the stator on the stator tray 4. The manual transfer and installation assembly a includes a handheld positioning plate a1 and a rotor adsorption transfer plate a2. The handheld positioning plate a1 has multiple limiting holes a12 for positioning and limiting the rotor, and the bottom of the rotor adsorption transfer plate a2 has multiple magnetic rods a21 for adsorbing the rotor fixed at equal intervals.

[0037] The top of the stator tray 4 is also provided with a positioning groove 42, and the bottom of the handheld positioning plate a1 is provided with a positioning protrusion a11 that cooperates with the positioning groove 42.

[0038] In this embodiment, the positioning groove 42 is a rectangular groove. Along the length of the handheld positioning plate a1, the length of the positioning groove 42 is greater than the length of the positioning protrusion a11. Along the width of the handheld positioning plate a1, the width of the positioning groove 42 is equal to the width of the positioning protrusion a11. After the positioning protrusion a11 fits into the positioning groove 42, it can push the handheld positioning plate a1 to move along the length of the positioning groove 42, so that the limiting hole a12 and the mounting groove 41 are aligned, and the rotor can be assembled from the limiting hole a12 onto the stator in the mounting groove 41, or the limiting hole a12 and the mounting groove 41 can be misaligned, so that when the rotor adsorption transfer plate a2 rises away, the handheld positioning plate a1 can limit the rotor on the stator.

[0039] In actual operation, the operator holds one end of the handheld positioning plate a1 with their left hand and inserts the positioning protrusion a11 into the positioning groove 42 on the stator tray 4, making the lower surface of the handheld positioning plate a1 in close contact with the upper surface of the stator tray 4. At this time, the limiting hole a12 will be aligned with the stator mounting groove 41 on the stator tray 4. Next, the operator holds the rotor adsorption transfer plate a2 with their right hand, causing the magnetic rod a21 at the bottom of the rotor adsorption transfer plate a2 to adsorb a row of rotors. Then, the rotor adsorption transfer plate a2 with the adsorbed rotors is moved along the limiting hole a12 to install a row of rotors onto the stator in the mounting groove 41. After installation, the operator moves the handheld positioning plate a1 horizontally, causing the limiting hole a12 and the mounting groove 41 to misalign. The edge of the limiting hole a12 presses against the rotor, and then the magnetic rod a21 moves away from the rotor, leaving the rotor mounted on the stator.

[0040] Through the coordinated work of the above components, the automatic installation equipment for the motor rotor can realize the automated installation of the stator and rotor, which greatly improves production efficiency, reduces labor costs, and ensures the accuracy and quality of installation.

[0041] Working principle of automatic motor rotor installation equipment:

[0042] Stator Conveying: The stator conveying line 2 consists of a stator conveying frame 21, a stator active conveyor roller 22, a stator driven conveyor roller 23, a stator conveyor belt 24, and a stator conveying motor 25. When the stator conveying motor 25 starts, it drives the stator active conveyor roller 22 to rotate, which in turn drives the stator driven conveyor roller 23 to rotate via the stator conveyor belt 24. This causes the stator tray 4 (containing stators) placed on the stator conveyor belt 24 to move along the stator conveying line 2 to the designated position.

[0043] Rotor Conveying: The structure of rotor conveying line 3 is similar to that of stator conveying line 2, consisting of rotor conveying frame 31, rotor active conveying roller 32, rotor driven conveying roller 33, rotor conveying belt 34, and rotor conveying motor 35. When rotor conveying motor 35 starts, it drives rotor active conveying roller 32 to rotate, which in turn drives rotor driven conveying roller 33 to rotate via rotor conveying belt 34. This causes the rotor tray 5 (containing the rotor) placed on rotor conveying belt 34 to move along rotor conveying line 3 to a designated position. The rotors are installed in rotor mounting slots 51 arranged in a strip-like array on rotor tray 5.

[0044] Rotor adsorption and assembly: The YZ-axis drive mechanism 6 on the frame 1 is a key component for achieving precise movement of the stator in space. The Y-axis linear motor 61 and the Z-axis cylinder 62 work together to enable the gripping part 8, which is fixed on the output end fixing plate 7 of the Z-axis cylinder 62, to move precisely in the Y and Z axes. Driven by the YZ-axis drive mechanism 6, the gripping part 8 moves above the rotor tray 5 and adsorbs the rotor in the rotor mounting slot 51.

[0045] After the rotor is adsorbed, the gripping part 8 moves above the stator tray 4 under the drive of the YZ axis drive mechanism 6, so that the rotor is gradually inserted into the stator mounting slot 41 on the stator tray 4, thus completing the assembly of the stator and rotor.

[0046] Empty rotor tray recycling: A pushing device 10 is installed on the rotor conveyor line 3 to push the empty rotor tray 5 onto the recycling conveyor line 9. The pushing device 10 includes a cylinder 101 fixed on the rotor conveyor frame 31, a push plate 102 fixedly connected to the output end of the cylinder 101, a baffle 103 fixed on the rotor conveyor frame 31, and a notch 104 provided on the rotor conveyor frame 31 directly opposite the push plate 102. When all the rotors on the rotor tray 5 are removed and it becomes empty, the cylinder 101 is activated, pushing the push plate 102 forward, pushing the empty rotor tray 5 from the rotor conveyor line 3 across the notch 104, and onto the recycling conveyor line 9 for recycling.

[0047] Cyclic operation: After the unloaded rotor tray 5 is pushed out, an employee on one side of the recycling conveyor line 9 manually places a full rotor tray 5 onto the rotor conveyor line 3. After assembly, the YZ axis drive mechanism 6 will continue to move back and forth to carry out the assembly of the next set of stators and rotors. At the same time, the stator conveyor line 2 and the rotor conveyor line 3 will continue to transport new stator trays 4 and rotor trays 5 to achieve continuous automated production.

[0048] Since rotor tray 5 has many rotors, the automatic assembly of the rotors by the gripping unit 8 takes a relatively long time. Meanwhile, an employee on one side of the recycling conveyor line 9 takes a stator tray 4 and a rotor tray 5 to be assembled, and then manually assembles the rotor with the stator on the stator tray 4 using the manual transfer and installation assembly component a. This allows employees to simultaneously handle the feeding of incoming rotors onto the rotor conveyor line 3 and manually assemble the stator and rotor, resulting in low overall cost and high efficiency.

[0049] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
