[0060] like Figure 1 As shown, the rotor iron ring pressing device includes a working platform 1, a feeding and pressing module 2, an iron ring feeding module 3, an iron ring picking module 4, and a pressing module 5. The feeding and pressing module 2, the iron ring feeding module 3, the iron ring picking module 4, and the pressing module 5 are all located on the working platform 1. The iron ring feeding module 3 is used to feed and position the iron ring. The feeding and pressing module 2 is used to feed and position the rotor and transport the iron ring from the feeding position to the pressing position. The iron ring picking module 4 is used to pick up the iron ring from the iron ring feeding module 3 and transfer it to the feeding and pressing module 2. Finally, the pressing module 5 picks up the iron ring and presses it onto the rotor. The following is a detailed description through specific embodiments.
[0061] like Figure 2As shown, the feeding and pressing module 2 includes a slide rail 21, a moving platform 22, a rotor feeding module 23, an iron ring picking platform 24, and a first drive module 25. The slide rail 21 consists of two rails arranged as a set and laid on the working platform 1. The moving platform 22 is slidably connected to the working platform 1 via the slide rail 21. The first drive module 25 is located on the working platform 1 and between the two slide rails 21. The moving platform 22 is located at the drive end of the first drive module 25. The rotor feeding module 23 and the iron ring picking platform 24 are located on the moving platform 22. The rotor feeding module 23 includes a rotor feeding platform 231 and a rotor fixing chamber 232. The rotor feeding platform 231 is supported by a support column. The rotor fixing chamber 232 is located on the rotor feeding platform 231 and consists of two arc-shaped vertical plates. The arc-shaped vertical plates do not touch each other end to end, forming a certain gap between them. A through hole is provided at the center of the circle formed by two arc-shaped vertical plates, and the rotor shaft can be inserted into the through hole. The rotor is picked up by a robot and placed in the rotor fixing chamber 232. The two arc-shaped vertical plates limit and fix the outside of the rotor. The gap between the arc-shaped vertical plates can be used by the robot to avoid obstacles when placing the rotor. The iron ring picking platform 24 includes a lower support platform 241, a fixing block 242 and an upper support platform 243. The lower support platform 241 is set on the rotor loading platform 231 by a support column. The upper support platform 243 is set on the lower support platform 241 by an elastic support member. The fixing block 242 is set on the upper support platform 243. The fixing block 242 is composed of three identical fan-shaped protrusions spaced apart. Its diameter is the same as the inner circle of the iron ring. The iron ring can be fitted onto the fixing block 242.
[0062] Preferably, the feeding and pressing module 2 also includes a moving platform blocking block 26 and a moving platform limiting structure 27. The moving platform blocking block 26 is disposed on the working platform 1 and located at both ends of the stroke of the moving platform 22, and is used to limit the movement of the moving platform 22. The moving platform limiting structure 27 includes a probe 271 and a sensing device 272. The sensing device 272 is disposed on the working platform 1 and located at both ends of the stroke of the moving platform 22. The probe 271 is disposed on the moving platform 22 and can pass through the sensing device 272. The sensing device 272 is used to determine the stroke of the moving platform 22.
[0063] like Figure 3As shown, the iron ring feeding module 3 includes an iron ring feeding platform 31, columns 32, and iron ring detection devices 33. The iron ring feeding platform 31 is mounted on the working platform 1 and located on both sides of the slide rail 21 via support columns. The columns 32 are mounted on the iron ring feeding platform 31, and multiple columns 32 are arranged around it (three are used as an example in this embodiment, which can limit the iron rings) to form a hopper. The iron ring detection devices 33 are located on both sides of the iron ring feeding platform 31. One is used to emit a light beam, and the other is used to receive the light beam. The position of the light beam is slightly higher than the surface of the iron ring feeding platform 31. When the light beam is blocked, it means that there are still iron rings in the hopper. If the light beam is received by one end, it means that the iron rings in the hopper have been used up, and an alarm will be issued. A pair of iron ring detection devices 33 corresponds to a hopper composed of columns 32. In this embodiment, there are two sets, but there can also be multiple sets.
[0064] like Figure 4 As shown, the iron ring material handling module 4 includes a second drive module 41, a gripper drive assembly 42, a connecting plate 43, and a gripper drive assembly limiting device 44. The second drive module 41 is a two-axis module that can drive the connecting plate 43 to move horizontally and vertically. The gripper drive assembly 42 is slidably connected to the connecting plate 43. A blocking plate is provided on the connecting plate 43. The blocking plate is located on one side of the movement direction of the gripper drive assembly 42. The blocking plate and the gripper drive assembly 42 are connected by a connecting rod. One end of the connecting rod is connected to the gripper drive assembly 42, and the other end passes through the blocking plate and is locked on one side of the blocking plate. The gripper drive assembly limiting device 44 is provided on the connecting rod, which can determine the movement position of the gripper drive assembly 42 (the working principle is the same as that of the moving platform limiting structure, and will not be described again). An elastic component is sleeved on the connecting rod to block the movement trend of the gripper drive assembly 42.
[0065] Preferably, the gripper drive assembly 42 includes a gripper drive part 421, an inner support gripper 422, and an adsorption gripper 423. The gripper drive part 421 is provided with an internal drive groove at intervals. The inner support gripper 422 is located in the internal drive groove and can move from the inside to the outside. The adsorption gripper 423 is provided at intervals on the gripper drive part 421, and the adsorption gripper 423 and the inner support gripper 422 are spaced apart. The adsorption surface of the adsorption gripper 423 is slightly higher than the clamping surface of the inner support gripper 422. The adsorption gripper 423 first adsorbs onto the surface of the iron ring, so that the iron ring is in a horizontal state. This avoids the iron ring being unable to be gripped when the inner support gripper 422 opens from the inside to the outside due to the relative tilt of the iron ring and the inner support gripper. This achieves the picking up of the iron ring.
[0066] like Figure 5As shown, the press-fit module 5 includes a drive module support platform 51, a third drive mechanism 52, a press-fit module connecting mechanism 53, and a press head module 54. The drive module support platform 51 is mounted on the working platform 1 via support columns. The third drive mechanism 52 is mounted on the drive module support platform 51. The press-fit module connecting mechanism 53 is located at the drive end of the third drive mechanism 52 and is sleeved on the support column supporting the drive module support platform 51, and is located below the drive module support platform 51. The press head module 54 is connected to the press-fit module connecting mechanism 53. The third drive mechanism 52 can drive the press-fit module connecting mechanism 53 to press down, thereby driving the press head module 54 to press down. The press-fit module connecting mechanism 53 includes a first connecting platform 531, a buffer block 532, and a guide ring 533. 33 is located at the four ends of the first connecting platform 531 and is sleeved on the support of the support platform 51 of the drive module. It plays a guiding role in the movement of the pressing module connecting mechanism 53. The buffer block 532 is located on the first connecting platform 531 and between the first connecting platform 531 and the drive module support platform 51 to prevent direct collision between the first connecting platform 531 and the drive module support platform 51. The pressing head module includes a second connecting platform 541 and a pressing head 542. The pressing head 542 is indirectly connected to the first connecting platform 531 through the second connecting platform 541. The top of the pressing head is provided with a cavity. The cavity is provided with a magnetic mechanism and a negative pressure mechanism. The shape of the cavity matches the iron ring. The magnetic mechanism is used to attract the iron ring. The negative pressure mechanism is used to detect the negative pressure in the cavity. If the iron ring is not attracted evenly, the negative pressure display is abnormal and an alarm will be triggered.
[0067] In summary, the iron ring is placed in the iron ring feeding device 3, and the feeding and pressing module 2 is located on the side away from the iron ring feeding device 3. After the rotor is placed in the rotor fixing chamber 232, the feeding and pressing module 2 moves toward the iron ring feeding device 3. At the same time, the iron ring picking module 4 picks up the iron ring from the iron ring feeding device 3 and places it on the feeding and pressing module 2 that has arrived at the iron ring feeding device 3. It should be noted that because the fixing block 242 is set with three fan-shaped intervals, when the inner support claw 422 is placed on the fixing block, the inner support claw 422 falls between the three fan-shaped protrusions, which can place the iron ring on the upper support platform 243, avoiding the obstruction of the fixing block 242. Then the moving platform 22 moves to the bottom of the pressing module, and the pressing head 542 picks up the iron ring and presses it onto the rotor, thus completing the installation of the rotor iron ring.
[0068] The above description is only the preferred embodiment disclosed in this utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
