In addition, the terms "first" and "second" are only used to distinguish in the description, and have no special meaning.

[0043] The rotor assembly press fitting device can improve the stability and reliability of the rotor assembly during the press fitting process, improve the production yield, and save costs.

[0044] As shown in Figure 1 , Figures 7-10 , the rotor assembly press fitting device mainly comprises a work platform 10, a support base 400, a first press head assembly 500, a second press head assembly 600, and a magnetic attraction assembly 16. The work platform 10 is provided with a second station 12 and a mechanical hand 14, and the mechanical hand 14 can carry the rotor assembly to the second station 12. The second station 12 is provided with the support base 400, the first press head assembly 500, the second press head assembly 600, and the magnetic attraction assembly 16. The first press head assembly 500 and the second press head assembly 600 are coaxially arranged, and the first press head assembly 500 and the second press head assembly 600 are located directly above the support base 400. The first press head assembly 500 is used for press fitting the commutator of the rotor assembly, and the second press head assembly 600 is used for press fitting the magnetic sensing coil on the shell of the rotor assembly. The magnetic attraction assembly 16 is located on one side of the rotor assembly, and is used for magnetically attracting the rotor assembly, so that the shell of the rotor assembly maintains a predetermined gap with the support base 400 when the first press head assembly 500 press fits the commutator.

[0045] Based on the above design, in the present embodiment, the mechanical hand 14 can carry the rotor assembly that has completed appearance detection at the first station 11 to the second station 12, and then the magnetic attraction assembly 16 can attract the rotor assembly. At this time, the rotor assembly is located directly above the support base 400, and the shell of the rotor assembly maintains a predetermined gap with the support base 400. The support base 400 is provided with a wedge-shaped block 410, and the work platform 10 is provided with a first driving cylinder 430. The output end of the first driving cylinder 430 is connected with a wedge-shaped rod 440, the inclined surface of the wedge-shaped rod 440 abuts against the inclined surface of the wedge-shaped block 410, and the wedge-shaped rod 440 can push the wedge-shaped block 410 to move upward in the support base 400, so that the wedge-shaped block 410 abuts against the shaft end of the rotor assembly. The support base 400 is also provided with a top block 420, which is arranged above the wedge-shaped block 410 and abuts against the wedge-shaped block 410. The top block 420 can abut against the shaft end of the rotor assembly.

[0046] Specifically, the first driving cylinder 430 is started, the first driving cylinder 430 can drive the wedge-shaped rod 440 to move, the inclined surface of the wedge-shaped rod 440 abuts against the inclined surface of the wedge-shaped block 410, the wedge-shaped rod 440 can push the wedge-shaped block 410, so that the wedge-shaped block 410 can move upwards inside the support base 400, the wedge-shaped block 410 pushes the top block 420 to move upwards, so that the top block 420 can abut against the lower end of the shaft body of the rotor assembly. Then the first pressing head assembly 500 is started, the first pressing head assembly 500 is lowered, so that the first pressing head assembly 500 can press the commutator of the rotor assembly, so that the position of the commutator meets the design requirements. During the pressing of the first pressing head assembly 500, the ejector rod in the support base 400 can support the shaft body of the rotor assembly, thereby avoiding the phenomenon that the rotor assembly rotates, improving the reliability and stability of the pressing. At the same time, during the pressing of the commutator, the magnetic attraction assembly 16 always magnetically attracts the rotor assembly, avoiding the phenomenon that the rotor assembly is displaced or tilted.

[0047] Then the first driving assembly drives the wedge-shaped rod 440 to retract, so that the wedge-shaped block 410 and the top block 420 can move downwards, at this time the top block 420 does not contact the shaft body of the rotor assembly, and the magnetic attraction assembly 16 still attracts the rotor assembly. Then the second pressing head assembly 600 is started, the second pressing head assembly 600 moves downwards, so that the second pressing head assembly 600 can press the magnetic sensing coil on the shell of the rotor assembly, so that the position of the magnetic sensing coil can meet the design requirements. Usually, during the pressing of the magnetic sensing coil by the second pressing head assembly 600, the pre-set gap between the shell of the rotor assembly and the support base 400 gradually decreases to zero, improving the reliability and stability of the pressing of the magnetic sensing coil by the second pressing head assembly 600.

[0048] Optionally, the pre-set gap in the embodiment is set to be between 2mm and 5mm. For example, it can be set to 2mm, 3mm, 4mm, 5mm, etc.

[0049] As Figures 7-8As shown, in this embodiment, the first pressure head assembly 500 includes a first guide post 510, a first pressure plate 520, a first pressure head 530, and a drive cylinder 540. The first guide post 510 is disposed on the working platform 10, the first pressure plate 520 is slidably sleeved on the first guide post 510, and the first pressure head 530 is disposed on the side of the first pressure plate 520 facing the rotor assembly. The first pressure head 530 is used to press and install the commutator, and the drive cylinder 540 is drivenly connected to the first pressure plate 520. The second pressure head assembly 600 includes a second guide post 610, a second pressure plate 620, a second pressure head 630, and a second drive cylinder 640. The second guide post 610 is disposed on the working platform 10, the second pressure plate 620 is slidably sleeved on the second guide post 610, the second pressure head 630 is disposed on the side of the second pressure plate 620 facing the rotor assembly, and the second pressure head 630 is used to press and install the magnetic coil. The second drive cylinder 640 is drivenly connected to the second pressure plate 620.

[0050] By integrating both the first pressure head assembly 500 and the second pressure head assembly 600 onto the working platform 10, and with the first pressure head 530 and the second pressure head 630 coaxially arranged, installation space can be saved, the rotor assembly pressing device can be miniaturized, costs can be reduced, and work efficiency can be improved.

[0051] like Figure 8 As shown, in this embodiment, the rotor assembly pressing device also includes a fastening component 700. The fastening component 700 is disposed on the working platform 10 and is located on one side of the rotor assembly. The fastening component 700 can hold the rotor assembly tightly.

[0052] Specifically, the fastening assembly 700 includes a clamping block 710 and a third drive cylinder 720. The third drive cylinder 720 is drivenly connected to the clamping block 710, which can clamp the rotor assembly. In actual operation, after the magnetic attraction assembly 16 attracts the rotor assembly, the output end of the third drive cylinder 720 drives the clamping block 710 to extend, enabling the clamping block 710 to clamp the rotor assembly. This further improves the stability and reliability of the rotor assembly during the press-fitting process, increases product yield, and saves costs.

[0053] This embodiment also provides a rotor assembly processing equipment, which includes the rotor assembly pressing device described above. The rotor assembly pressing device includes a work platform 10 and a robot arm 14. The robot arm 14 is mounted on the work platform 10 and can transport rotor assemblies from the transfer track to the work platform 10. This rotor assembly processing equipment can improve the reliability and stability of the rotor assembly pressing process, increase production yield, and achieve cost savings.

[0054] This embodiment also provides a rotor assembly appearance inspection device, which can improve inspection efficiency and product yield, save time and effort, and achieve the goal of cost saving.

[0055] like Figures 1-6 As shown, the rotor assembly appearance inspection device mainly includes a working platform 10, a shooting component 15, a rotating component 100, a first housing 140, a lifting component (not shown in the figure), a clamping component 200, and a movable component 150. The working platform 10 is provided with a first station 11 and a shooting component 15. The shooting component 15 is used to shoot the rotor assembly at the first station 11. The first workstation 11 is equipped with a rotating component 100, a first housing 140, a lifting component, a chuck assembly 200, and a movable component 150. The rotating component 100 passes through the work platform 10. The first housing 140 is connected to one end of the rotating component 100 and is located above the work platform 10. The lifting component and the movable component 150 are both located inside the first housing 140. The lifting component and the movable component 150 are drivenly connected. The lifting component can drive the movable component 150 to move up and down. The movable component 150 has a hollow structure. The chuck assembly 200 is inserted into the movable component 150. The movable component 150 can open and close the chuck assembly 200 during the lifting movement so that the chuck assembly 200 can loosen or clamp the rotor assembly.

[0056] Based on the above design, in this embodiment, a support part (not shown in the figure) is provided inside the first housing 140, and the clamp assembly 200 is disposed on the support part. This can provide a certain support for the clamp assembly 200, prevent the clamp assembly 200 from falling into the first housing 140, and improve the stability and reliability of the clamp assembly 200.

[0057] Optionally, the lifting component in this embodiment can be a cylinder, the movable part 150 can be a sleeve, and the output end of the cylinder is connected to the sleeve drive so that the cylinder can drive the sleeve to perform lifting and lowering movements.

[0058] like Figure 6 As shown, the chuck assembly 200 in this embodiment includes a rod portion 220 and a plurality of gripper portions 210. The plurality of gripper portions 210 are all disposed at one end of the rod portion 220. The plurality of gripper portions 210 can be opened and closed. The rod portion 220 is housed within the first housing 140, and the gripper portions 210 protrude from the end face of the first housing 140.

[0059] Specifically, when the chuck assembly 200 is not clamping the rotor assembly, the clamping jaw part 210 of the chuck assembly 200 is in an open state, the manipulator 14 can carry the rotor assembly to the chuck assembly 200, so that the shaft body of the rotor assembly can extend into the clamping jaw part 210, then the sleeve is driven to rise by the cylinder, so that the sleeve can close the clamping jaw part 210, at this time the clamping jaw part 210 can clamp the shaft body of the rotor assembly, then the rotating assembly 100 is started, the rotating assembly 100 drives the first shell 140 to rotate, thereby the chuck assembly 200 can drive the rotor assembly to rotate, and the shooting assembly 15 on the operation platform 10 can continuously shoot the rotor assembly, so as to detect the surface scratches or particulate foreign matter of the rotor assembly.

[0060] Further, the clamping jaw part 210 in the embodiment can be three, and the three clamping jaw parts 210 are annularly and uniformly distributed about the axis of the rod part 220. In this way, the clamping effect of the clamping jaw part 210 on the shaft body of the rotor assembly can be improved, and the risk of loosening or even falling off of the rotor assembly during rotation can be avoided, and the work efficiency can be improved. Of course, the number of clamping jaw parts 210 can be flexibly set by the operator according to actual needs, for example, four, five, six or the like, which will not be repeated here.

[0061] It should be noted that the lifting assembly and the first shell 140 in the embodiment are both conventional components in the art, and therefore the specific structure and working principle thereof will not be repeated here.
