The frame 1 includes a frame bottom plate 1-1. The feeding unit 2 includes a feeding channel 2-1 (that is, the space where the rotor balance block 4 is stored in the figure) and a pushing mechanism 2-2. The pushing mechanism 2-2 is arranged at the rear of the feeding channel 2-1. The material separating unit 3 is arranged at the front of the feeding channel 2-1. The material separating unit 3 includes a material separating mechanism 3-1 and a material separating temporary storage space 3-2 for temporarily storing a single rotor balance block 4 to be separated. The material separating mechanism 3-1 includes a vertically arranged lifting cylinder 3-11. A vertically upward material separating push plate 3-12 is connected to the output end of the lifting cylinder 3-11. The material separating temporary storage space 3-2 is located directly above the material separating push plate 3-12 and is vertically through. And, in the initial state of material separation, the top surface 3-121 of the material separating push plate is flush with the bottom surface of the feeding channel 2-1 (the top surface 2-111 of the channel bottom plate 2-11 in this embodiment). The distance between the top surface 3-121 of the material separating push plate and the bottom surface 3-21 of the material separating temporary storage space can enable the rotor balance block 4 to pass through smoothly.

[0066] Please also refer to Figure 1 and Figure 4As shown in the figure, in this embodiment, the feeding channel 2-1 includes a channel bottom plate 2-11. A channel 2-112 for the linear movement of the pushing mechanism 2-2 is provided at the longitudinal center of the channel bottom plate 2-11. The channel bottom plate 2-11 is located directly above the frame bottom plate 1-1 and is fixedly connected to the frame bottom plate 1-1 through a plurality of vertical support frames 5.

[0067] Please also refer to Figure 1 , Figure 5 and Figure 6 As shown in the figure, in this embodiment, the pushing mechanism 2-2 includes a pushing block 2-21 and a pushing drive assembly 2-22 for driving the linear movement of the pushing block 2-21. The pushing drive assembly 2-22 includes a pushing drive servo motor 2-221, a pushing lead screw 2-222, a pushing lead screw fixing flange 2-223, a pushing linear guide rail 2-224 and a pushing slider 2-225. The output end of the pushing drive servo motor 2-221 is drivingly connected to the head end of the pushing lead screw 2-222. There is a driving connection between the pushing lead screw fixing flange 2-223 and the pushing lead screw 2-222. The pushing slider 2-225 is slidably connected to the pushing linear guide rail 2-224. A pushing block fixing seat 2-23 is fixedly provided at the top of the pushing lead screw fixing flange 2-223.

The pushing linear guide rail 2-224 is fixed on the upper surface of the frame bottom plate 1-1. When the pushing drive servo motor 2-221 rotates, it will drive the rotation of the pushing lead screw 2-222 (the pushing lead screw 2-222 is connected to the head end fixing plate 2-24 and the tail end fixing plate 2-25 by rotatable bearings). The rotation of the pushing lead screw 2-222 will drive the linear movement of the pushing lead screw fixing flange 2-223. The linear movement of the pushing lead screw fixing flange 2-223 will drive the linear sliding of the pushing slider 2-225 on the pushing linear guide rail 2-224, thereby driving the linear movement of the pushing block fixing seat 2-23, and further driving the linear movement of the pushing block 2-21. As the pushing block 2-21 moves forward, the rotor balance block 4 located at its front end can be pushed into the material distribution unit 3.

[0068] As a preferred solution, a pushing start position sensor 2-3 and a pushing end position sensor 2-4 are provided on the frame bottom plate 1-1. A sensor detection point 2-2251 adapted to the pushing start position sensor 2-3 and the pushing end position sensor 2-4 is provided on the pushing slider 2-225. By providing the pushing start position sensor 2-3 and the pushing end position sensor 2-4, it is possible to avoid the phenomenon of over-movement when the pushing mechanism 2-2 performs forward pushing and backward resetting.

[0069] In addition, the output end of the pushing drive servo motor 2-221 in this embodiment is drivingly connected to the head end of the pushing lead screw 2-222 through a synchronous belt drive assembly 2-226. The synchronous belt drive assembly 2-226 includes a driving pulley 2-2261, a driven pulley 2-2262, and a synchronous belt 2-2263. The driving pulley 2-2261 is provided at the output end of the pushing drive servo motor 2-221, and the driven pulley 2-2262 is provided at the head end of the pushing lead screw 2-222. The rotation of the pushing drive servo motor 2-221 drives the driving pulley 2-2261 to rotate, thereby driving the rotation of the driven pulley 2-2262 through the synchronous belt 2-2263, and the rotation of the driven pulley 2-2262 drives the rotation of the pushing lead screw 2-222.

[0070] Please refer to Figure 6 As shown, in this embodiment, the pusher block fixing seat 2-23 includes a horizontal fixing plate 2-231, a first vertical fixing plate 2-232, and a second vertical fixing plate 2-233, where: the horizontal fixing plate 2-231 is fixed to the top of the pushing lead screw fixing flange 2-223, the first vertical fixing plate 2-232 is vertically fixed to the top of the horizontal fixing plate 2-231, the second vertical fixing plate 2-233 is connected to the first vertical fixing plate 2-232, and the pusher block 2-21 is horizontally provided at the front end of the second vertical fixing plate 2-233. The pushing lead screw fixing flange 2-223 drives the horizontal fixing plate 2-231 to perform a linear motion, thereby driving the first vertical fixing plate 2-232 to perform a linear motion, and further driving the second vertical fixing plate 2-233 to perform a linear motion, thus driving the linear motion of the pusher block 2-21.

[0071] As a preferred solution, the pusher block 2-21 in this embodiment is detachably connected to the front end of the second vertical fixing plate 2-233 through a quick-release connector 2-26. This design is convenient for replacing the pusher block 2-21 that is adapted to different specifications of the rotor balance block 4 to be pushed.

[0072] As a preferred solution, a telescopic spring 2-27 is provided between the first vertical fixing plate 2-232 and the second vertical fixing plate 2-233 in this embodiment. A material shortage detection sensor 2-28 is fixedly provided at the top of the first vertical fixing plate 2-232, and a sensor induction piece 2-29 adapted to the material shortage detection sensor 2-28 is fixedly provided at the top of the second vertical fixing plate 2-233. Through this design, the induction detection of whether there is material in the feeding channel 2-1 can be realized simultaneously. The specific working principle is: when there is a rotor balance block 4 abutted against the front end of the pusher block 2-21, the telescopic spring 2-27 is in a compressed state, thereby making the sensor induction piece 2-29 located at the top of the second vertical fixing plate 2-233 approach and engage with the material shortage detection sensor 2-28 located at the top of the first vertical fixing plate 2-232 (please refer toFigure 2 As shown; when there is no rotor balance weight 4 abutted against the front end of the pusher block 2-21, the telescopic spring 2-27 will extend to separate the sensor sensing piece 2-29 located at the top of the second vertical fixing plate 2-233 from the material shortage detection sensor 2-28 located at the top of the first vertical fixing plate 2-232 (please refer to Figure 22 and Figure 23 As shown).

[0074] As a preferred solution, a synchronous belt pressing wheel 2-1265 is provided on the outer side of the first-stage synchronous belt 2-1254 to ensure the stability of transmission.

[0075] Please refer to Figure 1 As shown, in this embodiment, the main body of the lifting cylinder 3-11 is fixedly connected to the frame bottom plate 1-1 through a fixing frame 6.

[0076] Please refer to Figure 1 and Figure 11 、 Figure 12 As shown, in this embodiment, the material distribution unit 3 further includes a material distribution push plate limiting mechanism 3-3. The material distribution push plate limiting mechanism 3-3 includes a front baffle 3-31, a rear fixing plate 3-32 and a thickness adjustment block 3-33.

And the thickness adjustment block 3-33 is detachably fixedly connected between the lower part of the front baffle 3-31 and the rear fixing plate 3-32. The lower part of the front baffle 3-31, the two thickness adjustment blocks 3-33 and the rear fixing plate 3-32 form an up-and-down through limiting channel adapted to the material distribution push plate 3-12 (i.e., the channel where the upper part of the material distribution push plate 3-12 is located in the figure), so as to play a guiding and limiting role in the up-and-down movement of the material distribution push plate 3-12. By providing the thickness adjustment block 3-33 and making the thickness adjustment block 3-33 be detachably fixedly connected between the lower part of the front baffle 3-31 and the rear fixing plate 3-32, the thickness adjustment block 3-33 adapted to the different specifications of the rotor balance block 4 to be distributed can be replaced, so as to form a limiting channel adapted to the size of the rotor balance block 4 to be distributed. This is because there are differences in the thickness dimensions and diameter dimensions of different specifications of the rotor balance block 4. In order to achieve a better material distribution and pushing function, the material distribution push plate 3-12 needs to be replaced with an adapted size specification according to different specifications of the rotor balance block 4. Therefore, the limiting channel needs to be adjusted accordingly to play a more accurate guiding and limiting role in the up-and-down movement of the material distribution push plate 3-12.

[0078] As a preferred solution, in this embodiment, first U-shaped openings 3-311 are symmetrically formed on both sides of the center of the top of the front baffle 3-31, and second U-shaped openings 3-221 corresponding to the two first U-shaped openings 3-311 are formed on both sides of the center of the top of the rear baffle 3-22. By providing the first U-shaped openings 3-311 and the second U-shaped openings 3-221, it is convenient for the manipulator to smoothly pick up the rotor balance blocks 4 located in the material distribution and temporary storage space 3-2. Please refer to Figure 19 and Figure 21 shown in the figure.

[0079] Please refer to Figure 1 and Figure 14 、 Figure 15 shown in the figure. In this embodiment, the material distribution unit 3 further includes a material distribution product limiting mechanism 3-4. The material distribution product limiting mechanism 3-4 includes material distribution product baffles 3-41 located on the left and right sides at the front end of the feeding channel 2-1 and a material distribution product baffle front and rear position adjusting mechanism 3-42. The front ends of the two material distribution product baffles 3-41 are respectively located on the left and right sides of the material distribution and temporary storage space 3-2 (please refer to Figure 21As shown in the figure, the front and rear position adjustment mechanism 3-42 of the material distribution product baffle includes a material distribution product baffle fixing block 3-421. A lower part of the material distribution product baffle fixing block 3-421 is provided with an L-shaped notch 3-4211. A slider 3-422 is fixedly arranged in the L-shaped notch 3-4211. The slider 3-422 is slidably connected with a linear slide rail 3-423. An upper part of the material distribution product baffle fixing block 3-421 is fixedly connected with an outer side part of a rear end of the material distribution product baffle 3-41. The linear slide rail 3-423 is fixedly arranged on an outer side part of a front end of the material retaining plate 2-121. A positioning seat 3-424 is fixedly arranged on a top of a vertical connecting plate 2-123 close to the linear slide rail 3-423. An equal-height adjusting screw 3-425 is arranged between the positioning seat 3-424 and an upper part of the material distribution product baffle fixing block 3-421. A compression spring 3-426 is sleeved on the equal-height adjusting screw 3-425 located between the positioning seat 3-424 and the material distribution product baffle fixing block 3-421; The material distribution product baffle 3-41 includes a horizontal part 3-411 and a vertical part 3-412 arranged above a front end of the horizontal part 3-411. Lower parts of two sides of the rear retaining block 3-22 are respectively provided with U-shaped channels 3-222 with openings facing downwards for the horizontal parts 3-411 of the corresponding side material distribution product baffles 3-41 to pass through (please refer to Figure 1 As shown in the figure), vertical parts 3-412 of the two-side material distribution product baffles 3-41 are respectively located on left and right sides of the material distribution temporary storage space 3-2, and front end faces of the vertical parts 3-412 of the two-side material distribution product baffles 3-41 are abutted against inner wall surfaces of the front baffle 3-31 (please refer to Figure 14 As shown in the figure and Figure 21 As shown in the figure). The provided material distribution product limiting mechanism 3-4 can limit the rotor balance block 4 located in the material distribution temporary storage space 3-2 to ensure that the manipulator can smoothly clamp the rotor balance block 4 located in the material distribution temporary storage space 3-2. Because the provided front and rear position adjustment mechanism 3-42 of the material distribution product baffle can realize the front and rear position adjustment of the material distribution product baffle 3-41. In addition, because the material distribution product baffle 3-41 is connected with the material channel width adjustment mechanism 2-12 (please refer to Figure 7 As shown in the figure), it can change its left and right positions along with the expansion or contraction of the material channel width adjustment mechanism 2-12. Therefore, the provided material distribution product limiting mechanism 3-4 can accurately limit different specifications of rotor balance blocks 4.

[0080] Please further combine with Figure 2 , Figure 3 , Figures 16 to 18 , Figure 20 and Figure 23As shown in the figure, in this embodiment, the material distribution unit 3 further includes a material distribution product anti-falling mechanism 3-5. The material distribution product anti-falling mechanism 3-5 includes a fixed seat 3-51. A spring fixed seat 3-52 is horizontally penetrated through the center of the fixed seat 3-51. A telescopic spring 3-53 is horizontally penetrated through the center of the spring fixed seat 3-52. A U-shaped opening 3-521 with an opening facing backward is provided at the rear end of the spring fixed seat 3-52. A roller 3-54 is fixedly installed in the U-shaped opening 3-521. A telescopic spring pressing block 3-55 is fixedly connected to the front end of the fixed seat 3-51. The front end of the telescopic spring 3-53 is fixedly connected to the telescopic spring pressing block 3-55. The rear end of the telescopic spring 3-53 abuts against the roller 3-54. Moreover, the rear end face of the fixed seat 3-51 is connected to the front side face of the front baffle 3-31. A through hole 3-312 for the front end of the roller 3-54 and the spring fixed seat 3-52 to pass through is provided on the front baffle 3-31. As a preferred solution, the top surface of the through hole 3-312 is basically flush with the bottom surface 2-113 of the material channel bottom plate 2-11. With such a design, when the lifting cylinder 3-11 fails and the material distribution push plate 3-12 cannot push the rotor balance block 4 located in the material distribution temporary storage space 3-2 upward, the roller 3-54 can be timely pushed into the space at the rear under the elastic force of the telescopic spring 3-53 to block the further falling of the falling rotor balance block 4.

[0081] As a preferred solution, in this embodiment, a material distribution initial position detection sensor 7 for sensing that the material distribution product reaches the top surface 3-121 of the material distribution push plate and a material distribution end position detection sensor 8 for sensing that the material distribution product reaches the material distribution temporary storage space 3-2 are provided on the front baffle 3-31.

[0082] The operation of realizing the automatic separate feeding of a batch of rotor balance blocks by using the device described in this application is as follows:

[0083] First, according to the size specification of the rotor balance block 4 to be fed, adjust the width of the feeding channel 2-1 to be adapted to the transverse size of the rotor balance block 4 to be fed, and select the adapted pushing block 2-21 and the material distribution push plate 3-12, and select the adapted rear stop block 3-22 and the thickness adjustment block 3-33 so that both the material distribution temporary storage space 3-2 and the limiting channel of the material distribution push plate 3-12 are adapted to the size specification of the rotor balance block 4 to be distributed, and adjust the front and rear positions of the material distribution product baffle 3-41 so that it can accurately limit the rotor balance block 4;

[0084] Then, manually or by a manipulator, put the batch of rotor balance blocks 4 to be fed into the feeding channel 2-1 in the same direction, as Figure 1 shown;

[0085] In the initial state of material distribution, the top surface 3-121 of the material distribution push plate is flush with the bottom surface of the feeding channel 2-1 (in this embodiment, it is the top surface 2-111 of the channel bottom plate 2-11 of the feeding channel). Therefore, when the rotor balance weight 4 in the feeding channel 2-1 is pushed to the top surface 3-121 of the material distribution push plate, it will be detected by the initial position detection sensor 7 of the material distribution (please refer to Figure 2 and Figure 3 as shown). Then, the controller will start the lifting cylinder 3-11 to rise, thereby driving the material distribution push plate 3-12 to move upward, so that the rotor balance weight 4 located on its top surface is pushed into the material distribution temporary storage space 3-2. At this time, it will be detected by the end position detection sensor 8 of the material distribution (please refer to Figure 20 as shown). Then, the controller makes the manipulator (not shown in the figure) pick up the rotor balance weight 4 located in the material distribution temporary storage space 3-2. After the manipulator picks it up, the controller will make the lifting cylinder 3-11 descend, thereby driving the material distribution push plate 3-12 to descend to the initial position. Then, the pushing drive assembly 2-22 is started to make the pusher block 2-21 move forward in a straight line to push the rotor balance weight 4 in the feeding channel 2-1 forward until the next rotor balance weight 4 reaches the top surface 3-121 of the material distribution push plate. Then, the lifting cylinder 3-11 is started to rise again, and the material distribution push plate 3-12 is driven to move upward again, so that the current rotor balance weight 4 located on its top surface is pushed into the material distribution temporary storage space 3-2 to be picked up by the manipulator. This cycle repeats. When the current batch of rotor balance weights 4 in the feeding channel 2-1 is completely pushed away, since there is no rotor balance weight 4 at the front end of the pusher block 2-21 to abut against it, the telescopic spring 2-27 will stretch, causing the sensor sensing piece 2-29 located at the top of the second vertical fixing plate 2-233 to be separated from the material shortage detection sensor 2-28 located at the top of the first vertical fixing plate 2-232 (please refer to Figure 22 and Figure 23 as shown). The controller (not shown in the figure) will remind to replenish the feeding channel 2-1 by monitoring the disconnection signal between the material shortage detection sensor 2-28 and the sensor sensing piece 2-29.

[0086] As described above, it can be seen that by using the device of the present invention, automatic batch feeding of rotor balance weights can be realized, and it can cooperate with the manipulator to realize automatic feeding of rotor balance weights. It can not only effectively avoid the defects of high labor cost, high labor intensity, and low production efficiency existing in manual feeding, but also effectively avoid the risk that the direction of the rotor balance weight is easily misaligned during manual feeding, resulting in abnormal subsequent assembly operations. It has significant application value for realizing highly automated rotor assembly production.

[0087] Finally, it is necessary to point out here that: The above description is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
