[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0029] Example 1: See Figure 1-4As shown, a bearing feeding mechanism for a driver motor includes a feeding block 51 and a feeding component mounted on a table panel 11. The feeding block 51 is provided with a feeding trough 52 that is arranged downwardly and tilted from the outside to the inside. The top of the outer end of the feeding trough 52 is connected to the top surface of the feeding block 51.

[0030] The front side of the loading block 51 is provided with a discharge port 53 communicating with the inner end of the feeding trough 52, and the rear side of the loading block 51 is provided with a through opening 54 communicating with the inner end of the feeding trough 52, and the through opening 54 is arranged opposite to the discharge port 53;

[0031] The feeding component is installed on the rear side of the loading block 51, and the feeding component includes a feeding cylinder 55 and a feeding rod 56. The feeding cylinder 55 is installed on the rear side of the loading block 51, and the rear end of the feeding rod 56 is connected to the output shaft of the feeding cylinder 55. The front end of the feeding rod 56 is inserted into the through opening 54. The feeding cylinder 55 drives the feeding rod 56 to move forward and backward. When the output shaft of the feeding cylinder 55 is retracted, the front end of the feeding rod 56 is retracted into the through opening 54; when the output shaft of the feeding cylinder 55 is extended, the front end of the feeding rod 56 passes through the feeding trough 52 and the discharge port 53 and is arranged on the front side of the loading block 51.

[0032] In the present invention, a discharge portion 3 is provided in the middle of the table panel 11, and the motor rotor 12 is transported from front to back through the discharge portion. Two sets of bearing feeding mechanisms are respectively provided on both sides of the discharge portion, and a bearing pressing mechanism 6 is provided on the front side of each bearing feeding mechanism. In this arrangement, mechanisms can be provided on both sides of the extension direction of the discharge portion as much as possible, and the space on both sides of the discharge portion for transporting the motor rotor can be fully utilized, which can reduce space waste and enable the motor rotor to be placed on an automated assembly line during the manufacturing process, with the bearing pressing process being in one of the processes. In this embodiment, the bearing 13 enters the feed trough from the top of the outer end of the feed trough, and the bearing rolls inward through the inclined feed trough to the feed trough at the discharge port. After rolling into the feed trough at the discharge port, it waits for the bearing pressing mechanism to receive the material. When a bearing is fed into the bearing pressing mechanism, the output shaft of the feed cylinder extends, driving the feed rod forward, pushing the bearing out of the discharge port and into the bearing pressing mechanism, and then the output shaft of the feed cylinder retracts to its original position (when the feed rod moves forward, it will block the bearing next to the feed trough at the discharge port position to prevent the bearing from rolling inward into the feed trough at the discharge port), and then the next bearing will continue to roll inward into the feed trough at the discharge port.

[0033] See also Figure 1-3 As shown, the feeding cylinder 55 is connected to the rear side of the loading block 51 via a mounting bracket 57 .

[0034] In this embodiment, the distance between the feed trough and the rear end surface of the loading block is relatively short, and the bearing is pushed out of the discharge port at a certain distance. The feed rod requires a certain length. Therefore, in order to ensure that the front end of the feed rod can be retracted into the through opening after the output shaft of the feed cylinder retracts, the mounting frame is set to set the feed cylinder backward away from the feed trough, so that the front end of the feed rod can be retracted into the through opening, and when the output shaft of the feed cylinder extends, the feed rod can push the bearing out of the feed trough and the discharge port.

[0035] See also Figure 1-3 As shown, the loading block 51 includes a rear side plate 510, a middle piece 511 and a shielding plate 512. The middle piece 511 is provided with a connecting opening facing outward. The middle piece 511 is mounted on the front side of the rear side plate 510. The shielding plate 512 is connected to the front side of the middle piece 511. The connecting opening between the shielding plate 512 and the rear side plate 510 constitutes the feeding chute 52.

[0036] The feeding component is installed on the rear side of the rear side plate 510 , and the through opening 54 is provided on the rear side plate 510 .

[0037] In this embodiment, the loading block is composed of three parts, which is convenient for assembly, maintenance and replacement, and also convenient for processing the feeding trough.

[0038] See also Figure 2 、 3 As shown, there is a distance between the inner end surface of the shielding plate 512 and the inner end surface of the connecting opening, and the inner end of the shielding plate 512 and the inner end of the connecting opening form the discharge port 53.

[0039] The middle member 511 includes an upper inclined plate 513, a lower inclined plate 514, and a C-shaped plate 515. The lower inclined plate 514 is arranged parallel to and below the upper inclined plate 513. The upper inclined plate 513 and the lower inclined plate 514 are arranged downwardly and inclined from the outside to the inside. The outer end of the C-shaped plate 515 is provided with a C-shaped opening 516. The inner ends of the upper inclined plate 513 and the lower inclined plate 514 are connected to the outer end surface of the C-shaped plate 515, and the distance between the upper inclined plate 513 and the lower inclined plate 514 is arranged to correspond to the C-shaped opening 516.

[0040] The shielding plate 512 is installed on the front side surfaces of the upper inclined plate 513 and the lower inclined plate 514. The inner end surface of the shielding plate 512 is flush with the inner end surfaces of the upper inclined plate 513 and the lower inclined plate 514. The front end of the C-shaped opening 516 constitutes the discharge port 53.

[0041] In this embodiment, the middle piece is composed of three parts, which is convenient for manufacturing and processing and reduces material consumption.

[0042] See also Figure 1 As shown, a material blocking component is also provided, which includes a material blocking cylinder 520 and a material blocking plate 521. A material blocking slider 522 is placed on the top surface of the loading block 51, and the material blocking cylinder 520 is installed on the top surface of the loading block 51. The output shaft of the material blocking cylinder 520 is connected to the material blocking slider 522, and the material blocking plate 521 is arranged on the front side of the loading block 51, and the top rear side of the material blocking plate 521 is connected to the front end of the material blocking slider 522; when the output shaft of the material blocking cylinder 520 is retracted, the material blocking plate 521 is arranged in the discharge port 53, and when the output shaft of the material blocking cylinder 520 is extended, the material blocking plate 521 is moved and arranged next to the discharge port 53.

[0043] In this embodiment, the material blocking plate is located at the inner end of the shielding plate, which is located at the front side of the C-shaped plate.

[0044] In this embodiment, when the bearing is in the feed trough, the axis of the bearing is parallel to the feed rod. Therefore, when the bearing rolls inward to the feed trough at the discharge port, the bearing may fall out of the discharge port. Therefore, in order to ensure that each bearing does not fall out of the discharge port when it rolls inward to the feed trough at the discharge port, a blocking component is also provided. When the bearing rolls inward to the feed trough at the discharge port, the output shaft of the blocking cylinder retracts, driving the blocking slider and the blocking plate to move outward, so that the blocking plate is in the discharge port, and it will rest on the baffle plate and can also be limited by the baffle plate. At this time, when the bearing rolls inward to the feed trough at the discharge port, the bearing will be blocked by the blocking plate and will not fall out of the feed trough. When the feed rod needs to push the bearing out of the inner end of the feed trough and onto the bearing press-fitting mechanism, the output shaft of the stopper cylinder extends, driving the stopper plate to move inward and away from the discharge port. Then the feed component sends the bearing from the feed trough and the discharge port into the bearing press-fitting mechanism, and this cycle continues to ensure the stability of the bearing feeding. In the utility model, after the bearing press-fitting mechanism receives the bearing, the axis of the bearing will be perpendicular to the axis of the motor rotor. Therefore, the bearing press-fitting mechanism can also be flipped 90 degrees so that the bearing and the motor rotor are coaxial, so as to ensure that the bearing press-fitting mechanism can smoothly, quickly and stably press-fit the bearing onto the motor rotor.

[0045] See also Figure 1-4 As shown, a material support plate 523 is further provided at the rear side of the outer end of the feeding trough 52 , and the front end of the material support plate 523 is connected to the loading block 51 .

[0046] A plurality of V-shaped brackets 524 are spaced apart on the material support plate 523 . The plurality of V-shaped brackets 524 are spaced apart from front to back, and the V-shaped brackets 524 are in communication with the outer top of the feeding trough 52 .

[0047] In this embodiment, the top of the outer end of the shielding plate is opposite the V-shaped bracket. In this way, multiple bearings can be placed in each V-shaped bracket from front to back, with the bearing axis parallel to the extension direction of the V-shaped bracket. The material support plate can be tilted downward from back to front and automatically slide forward by gravity, so that the bearing at the front end of the V-shaped bracket falls into the feed trough (the width of the feed trough is slightly larger than the thickness of a bearing. Therefore, at most only one bearing in each V-shaped bracket can move forward and fall into the feed trough at a time. The feed trough at the front end of the material support plate can also be stacked from bottom to top, with the excess bearings still in the V-shaped bracket. Alternatively, a lifting component, such as a spring or cylinder, is set at the rear end of the V-shaped bracket to push the bearing forward so that the bearings fall into the feed trough one by one. In this way, the top space is minimized and the space on both sides of the extension direction of the discharge portion is sufficient. Corresponding mechanisms can be set on both sides of the motor rotor conveying direction to facilitate the press-fitting of the motor rotor bearings and the arrangement of other motor rotor assembly mechanisms.
