[0044] The implementation of the present invention will be described in detail below in conjunction with specific embodiments.

[0045] In this embodiment:

[0046] Refer to Figure 1-2 As shown, a preferred embodiment is provided by the present invention.

[0047] The automatic assembly equipment for the motor rotor of this embodiment includes an assembly bin 1, two sets of material supporting belt conveyors 2, one set of feeding belt conveyor 3 and an electric control box 4 distributed around the assembly bin 1. A number of feeding trays 24 are conveyed on the two sets of material supporting belt conveyors 2 through belts. The feeding trays 24 are used to hold the motor rotor and keep the axis of the motor rotor upward. And the height of one set of material supporting belt conveyor 2 is higher than that of the other set of material supporting belt conveyor 2. The feeding belt conveyor 3 is used to convey the motor stator to the assembly bin 1;

[0048] A control panel 11 is installed on one side of the assembly bin 1, and a steering wheel 12 is installed inside the assembly bin 1. Assembly slots 126 for receiving the motor rotor are evenly distributed on the steering wheel 12. An upper material gripper 14 is arranged above one side of the steering wheel 12 close to the feeding belt conveyor 3. The upper material gripper 14 is used to transfer the motor stator on the feeding belt conveyor 3 to the assembly bin 1;

[0049] An assembly machine 13 is also installed inside the assembly bin 1. The assembly machine 13 includes two sets of assembly plates 134 arranged above and below the steering wheel 12. The two assembly plates 134 move synchronously and in opposite directions. Assembly rings 135 and top plates 132 for assembling the motor rotor and the motor stator are installed on the assembly plates 134.

[0050] Among them, the electric control box 4 is used to supply power to each component of the equipment. The control panel 11 includes a touch panel and a PLC of model S4 - 400, which realizes the real-time control of each electrical component through programming to complete the automatic assembly operation.

[0051] During the process of conveying the motor stator from the feeding belt conveyor 3 into the assembly bin 1, refer to the attachedFigure 5 As shown, a lifting and telescoping machine 141 is installed at the top of the assembly bin 1. The feeding gripper 14 is installed on the telescoping part of the lifting and telescoping machine 141. A guide rod 142 passing through the top of the assembly bin 1 is also provided at the top of the feeding gripper 14. The feeding gripper 14 includes an electromagnetic member 143, and an adsorption ring 144 is installed on the magnetic adsorption part of the electromagnetic member 143. The adsorption ring 144 is driven by the lifting and telescoping machine 141 to move up and down, and the electromagnetic member 143 is used to magnetize the adsorption ring 144, so that the motor stator above the end of the feeding belt conveyor 3 can be adsorbed. Since the adsorption ring 144 is annular and the motor stator is also annular, after the two are adsorbed, the motor stator can be adsorbed towards the center position of the adsorption ring 144, so that the motor stator can be placed above the steering wheel 12, facilitating the motor stator to fall off after the adsorption ring 144 is powered off and demagnetized to be sleeved outside the motor rotor;

[0052] In the attachment Figure 5 As shown, a bracket 121 is installed on the inner side of the bottom of the assembly bin 1. A stepping steering motor 122 is installed on the inner side of the bottom of the bracket 121. The output shaft of the stepping steering motor 122 is connected to the bottom of the steering wheel 12. The steering wheel 12 is driven by the stepping steering motor 122 to perform stepping rotation, so as to continuously convey the motor rotor onto the feeding gripper 14, sleeve it into the motor stator and send it into the assembly machine 13 for assembly operation.

[0053] It should be noted that in order to be able to step-convey the above-mentioned motor rotor through the steering wheel 12, referring to the attachment Figure 3 As shown, clamping pieces 123 are connected to the periphery of the steering wheel 12 through spring shafts on the periphery of the assembly groove 126. A rotating ring 124 is connected to the outside of the clamping pieces 123 through bearings on the assembly groove 126. A clamping telescoping machine 125 is installed on one side of the assembly groove 126 of the steering wheel 12. The telescoping part of the clamping telescoping machine 125 is connected to the rotating shaft on one side of the rotating ring 124. A wedge-shaped block 1231 is provided on the side of the clamping piece 123 close to the rotating ring 124. An extrusion block 1241 corresponding to the wedge-shaped block 1231 is provided on the inner wall of the rotating ring 124. An anti-inclined surface corresponding to the inclined surface of the wedge-shaped block 1231 is provided on one side of the extrusion block 1241. The rotating ring 124 is rotated along the anti-inclined surface direction by the pushing of the clamping telescoping machine 125. When the rotating ring 124 rotates under the pushing of the telescoping part of the clamping telescoping machine 125, the wedge-shaped block 1231 of the clamping piece 123 will be pushed by the anti-inclined surface of the extrusion block 1241, and then the clamping piece 123 will be pushed to close synchronously, realizing the clamping and fixing operation of the electrode rotor;

[0054] Referring to the attachment Figure 6As shown, the assembly machine 13 further includes a limit telescopic machine 131 and an assembly telescopic machine 133 installed at the upper and lower parts of the assembly bin 1.

A conical groove is formed inside the pressure cylinder 1321. By pressing against the end of the shaft of the main motor rotor with the pressure cylinder 1321, it can be kept in a centered state;

[0055] Further, referring to the attached Figure 7 As shown, the assembly plate 134 is fixedly installed on the telescopic part of the assembly telescopic machine 133. An assembly ring 135 and an adjustment motor 136 are arranged on the assembly plate 134. A number of guide grooves 1351 are circumferentially distributed on the assembly ring 135. The ends of the guide grooves 1351 are connected with support rods 137 through rotating shafts. The adjustment motor 136 is used to drive a number of the support rods 137 to rotate synchronously along the axial direction of the assembly ring 135. The inner wall of the assembly ring 135 is connected with an adjustment ring 139 through a bearing. Tooth grooves are arranged on the outer surface of the adjustment ring 139. A driving gear 1361 for driving the adjustment ring 139 to rotate is sleeved on the output shaft of the adjustment motor 136. An adjustment rod 138 is connected with the inner part of the guide groove 1351 through a bearing. A transmission bevel gear 1381 is sleeved on the end of the adjustment rod 138. An inclined tooth groove for driving the transmission bevel gear 1381 to engage is formed at the top of the adjustment ring 139. A connecting block 1371 is threadedly connected to the outside of the adjustment rod 138. An inclined support rod 1372 is connected with a rotating shaft between the connecting block 1371 and one side of the support rod 137. Driven by the adjustment motor 136, the adjustment ring 139 will drive the transmission bevel gear 1381 to rotate, and then drive a number of adjustment rods 138 to rotate synchronously. The adjustment rods 138 will push the connecting blocks 1371 threadedly connected to their outsides to slide inside the guide grooves 1351. During the sliding process, the connecting blocks 1371 will push a number of support rods 137 to rotate and open and close synchronously along the axial direction of the assembly ring 135 through the inclined support rods 1372, so as to be able to perform support adjustment according to the specifications of the motor stator and the motor rotor, so that the telescopic part of the assembly telescopic machine 133 can be used to push the lower part of the motor rotor and the upper part of the motor stator synchronously through the support rods 137 at the upper and lower parts, and press the two together for assembly;

[0056] In the attached Figure 2 and attached Figure 4In the embodiment, a first tripod 21 connected to one side of the assembly bin 1 is installed below the end of the material supporting belt conveyor 2, a feeding telescopic machine 22 is installed on the top of the first tripod 21, and the telescopic part of the feeding telescopic machine 22 is connected to the end of the material supporting belt conveyor 2, and a second tripod 23 is also installed below the other end of the material supporting belt conveyor 2, and a roller is installed at the bottom of the second tripod 23. Driven by the telescopic part of the feeding telescopic machine 22, the material supporting belt conveyor 2 can reciprocate toward the direction of the assembly bin 1, and the feeding tray 24 includes a U-shaped bracket 241, and the feeding tray 24 is connected by the vertical end rotating shaft of the U-shaped bracket 241, and counterweight blocks 242 are arranged on both sides of the bottom of the feeding tray 24, and the side walls of the feeding tray 24 are also installed There are two groups of lifting telescopic machines 243, the telescopic parts of the two lifting telescopic machines 243 extend to the inside of the feeding tray 24, and are equipped with a supporting piece 244, which is pushed out by the lifting telescopic machine 243 to lift the motor rotor. Under the action of the counterweight block 242, the feeding tray 24 with the rotating shaft installed on the U-shaped bracket 241 can always keep the axis of the motor rotor upward when lifting the motor rotor. When the motor rotor is transported to the assembly warehouse 1, the feeding telescopic machine 22 will push the supporting belt conveyor 2 toward the assembly warehouse 1, so that the motor rotor is placed above the assembly groove 126 of the steering wheel 12, and then the supporting piece 244 is driven by the telescopic part of the lifting telescopic machine 243 to contract and release the motor rotor, so that the motor rotor is transferred to the assembly groove 126;

[0057] Similarly, when it is necessary to unload and transport the assembled motor rotors and motor stators, a shorter set of supporting belt conveyors 2 is moved toward the assembly bin 1 through the feeding telescopic machine 22, and the motor rotors and motor stators that fall off the assembly groove 126 are received by the feeding tray 24.

[0058] The present embodiment uses a plurality of sets of matching equipment to complete the precise assembly of the motor rotor and the motor stator. First, the supporting belt conveyor 2 conveys the motor rotor through the feeding tray 24 and keeps its axis upward to the assembly bin 1. During this process, the feeding belt conveyor 3 conveys the motor stator to the assembly bin 1. Through the coordinated action of the loading gripper 14 and the lifting and telescopic machine 141, the motor stator is adsorbed by the adsorption ring 144 and transferred to the top of the assembly groove 126 of the steering wheel 12. The motor stator is released by the lifting and telescopic machine 243 to be inserted into the outside of the motor rotor in the assembly groove 126. Under the extrusion and cooperation of the two sets of assembly plates 134 and the two sets of assembly rings 135 of the assembly machine 13, the assembly of the rotor and the stator is completed. Finally, through the precise control of the stepping steering motor 122, the clip 123 and other components, the precise combination and feeding of the rotor and the stator are ensured.
