[0115] See also Figure 5 , the tray assembly 15 comprises:

[0116] The pallet positioning bars 151 are relatively fixed to one side of the second frame 8, and the pallets can be stacked and inserted in the cavity surrounded by the four pallet positioning bars 151;

[0118] The support plate 153 , which is used for supporting the stacked trays, is fixed to the moving end of the first linear motor 152 , and one side of the support plate 153 is located between the four tray positioning bars 151 .

[0119] It should be noted that after the commutator on a pallet is used, the pallet is placed inside the four pallet positioning bars 151 by the robot, and the first linear motor 152 drives the pallet to move downward by the thickness of a pallet, so that the empty pallet is stacked at the bottom.

[0120] See also Figure 5 , the transplanting assembly 16 comprises:

[0121] A second linear motor 161, wherein the second linear motor 161 is fixed on a side of the second frame 8 close to the tray assembly 15;

[0124] The first finger clamp 164 is fixed to the protruding end of the first cylinder 163 , and the first finger clamp 164 is located above the tray assembly 15 .

[0125] It should be noted that the commutator on the pallet can be picked up through the transfer assembly 16. By driving the first cylinder 163 to extend, the first finger clamp 164 reaches a commutator, and a commutator is clamped by the first finger clamp 164, and then retracted by driving the first cylinder 163, and then the commutator is moved to a position in the middle of the second finger clamp 173 by driving the second linear motor 161 and the third linear motor 162.

[0126] See also Figure 6 , the flip assembly 17 comprises:

[0127] A vertical plate 171, wherein the vertical plate 171 is fixed on a side of the second frame 8 close to the tray assembly 15;

[0128] A first rotating motor 172, wherein the first rotating motor 172 is fixed to one side of the upper end of the vertical plate 171;

[0129] The second finger clamp 173 is fixed to the output end of the rotating motor.

[0130] It should be noted that the flipping assembly 17 can flip the commutator, and after the commutator reaches the inner side of the second finger clamp 173, the second finger clamp 173 drives to clamp the commutator, and then the first finger clamp 164 is released and moves away from the commutator under the action of the second linear motor 161, the third linear motor 162 and the first cylinder 163 to pick up the material of the next commutator, and then drives the first rotating motor 172 to rotate, thereby driving the second finger clamp 173 to rotate, thereby realizing the commutation of the commutator.

[0131] See also Figure 8 and Fig. 9 , the positioning component 18 includes:

[0132] A positioning base 181, wherein the positioning base 181 is fixed on the second frame 8;

[0133] A second rotating motor 182, wherein the second rotating motor 182 is fixed to one side of the lower end of the positioning base 181;

[0134] A second cylinder 183, wherein the second cylinder 183 is fixed to the output end of the second rotating motor 182, and the protruding end of the second cylinder 183 passes through the positioning base 181 and extends to the top of the positioning base 181;

[0135] A sliding sleeve 184, wherein the sliding sleeve 184 is fixed to one side of the outer wall of the positioning base 181;

[0136] A lifting slide bar 185, wherein the lifting slide bar 185 is slidably connected to the inner wall of the sliding sleeve 184;

[0137] A lifting seat 186, wherein the lifting seat 186 is fixed to the top of the lifting slide rod 185, and the bottom of the lifting seat 186 is in contact with the top of the sliding sleeve 184;

[0138] A sliding block 187, wherein the sliding block 187 is slidably connected to the top of the lifting seat 186 via a linear slide rail;

[0140] The third cylinder 189 is fixed to one side of the top of the lifting seat 186 , and the protruding end of the third cylinder 189 is fixed to the outer wall of the sliding block 187 .

[0141] It should be noted that the translational pressing assembly 19 can remove the commutator on the second finger clamp 173 and move it to just above the second cylinder 183 on the positioning base 181, and when the next commutator is taken out, the previous commutator can be removed and pressed onto the rotor shaft. While the commutator is moved and placed on the positioning base 181, the second cylinder 183 extends, and the extended end of the second cylinder 183 is inserted into the middle of the commutator. The extended end of the second cylinder 183 has an interference fit with the inner side of the commutator. Then the translational pressing assembly 19 performs the next commutator taking out work. During this process, the second cylinder 183 continues to extend upward, and before the second cylinder 183 extends upward again, the third cylinder 189 is driven to extend, thereby pushing the positioning card plate 188 to a position just above the commutator. As the second cylinder 183 extends upward again, the third cylinder 189 is driven to extend, thereby pushing the positioning card plate 188 to a position just above the commutator. When the cylinder 183 is extended, the positioning card plate 188 can contact the top of the commutator, and under the push of the commutator, the lifting slide rod 185 slides upward along the inner wall of the sleeve 184, and the positioning card plate 188 also slides upward. When the second cylinder 183 is extended, the second rotating motor 182 is driven to rotate, driving the commutator to rotate slowly. Finally, after the positioning card plate 188 is aligned with the groove on the commutator, the positioning card plate 188 falls downward under the action of gravity and is stuck in the groove on the side of the commutator, thereby completing the positioning of the commutator, and then the translation pressing assembly 19 is used to pick up the next commutator. At the same time, the previous commutator that has been positioned can be removed, and then the positioned commutator is pressed onto the rotor shaft. The removed new commutator is simultaneously placed directly above the second cylinder 183 on the positioning base 181.

[0142] See also Fig. 9 The axial cross-sections of the sliding sleeve 184 and the lifting slide rod 185 are both arranged in a regular hexagon, which can ensure that the lifting slide rod 185 can stably slide up and down along the inner wall of the sliding sleeve 184 without rotating.

[0143] See also Figure 7 , the translation pressing component 19 includes.

[0144] A support plate 191, wherein the support plate 191 is fixed on one side of the second frame 8 close to the positioning base 181;

[0145] A fourth cylinder 192, wherein the fourth cylinder 192 is fixed to the upper end of the support plate 191;

[0146] The fourth linear motor 193, two of the fourth linear motors 193 are symmetrically slidably connected to the outer wall of the support plate 191 near the side of the positioning base 181, and the extended end of the fourth cylinder 192 is fixed to the outer wall of the fourth linear motor 193;

[0147] A third finger fixture 194, wherein the third finger fixture 194 is fixed to the bottom of the moving end of the fourth linear motor 193;

[0148] A transverse plate 195, wherein the transverse plate 195 is fixed to the moving end of the fourth linear motor 193;

[0149] The electromagnet assembly 196 is fixed on a side of the surface of the transverse plate 195 away from the third finger clamp 194 .

[0150] It should be noted that, by driving the moving end of the fourth linear motor 193 to move downward, and then driving the moving end of the fourth linear motor 193 to move upward, and then driving the fourth cylinder 192 to extend, and then driving the moving end of the fourth linear motor 193 to move downward again, after completing the pressing work, the moving end of the fourth linear motor 193 moves upward again, and then the fourth cylinder 192 is retracted. During this process, the electromagnet assembly 196 is energized to adsorb the commutator when it reaches the flip assembly 17, and then the commutator is placed on the positioning base 181. The power is turned off and the magnetic attraction is lost. A third finger clamp 194 close to one side of the electromagnet assembly 196 can clamp the commutator and move it to the position of the extended end of the second cylinder 183 above the positioning base 181, and a third finger clamp 194 at the end is used to clamp the commutator after positioning and press it onto the rotor shaft.

[0151] See also Fig.10 and Fig.11 , the unloading device 21 comprises:

[0160] It should be noted that after the commutator is installed, the rotor shaft moves toward one side of the unloading device 21. After moving into position, the seventh cylinder 218 is driven to extend, pushing the unloading longitudinal plate 213 downward into position, and then the sixth cylinder 217 is driven to extend, thereby pushing the finger cylinder mounting plate 215 to flip downward, so that the fourth finger clamp 216 is located on the outside of the rotor shaft, and the rotor shaft is clamped by the fourth finger clamp 216, and then the seventh cylinder 218 is driven to retract.
