Through the transverse sliding driving assembly 2-125 and the transverse sliding assembly 2-124, the material blocking plate 2-121 arranged on the left and right sides of the feeding channel 2-1 can realize outward expansion or inward contraction movement, so as to realize the adjustment of the width of the feeding channel 2-1, and better adapt to the feeding requirements of different specifications of rotor balancing blocks.

[0074] As a preferred solution, a synchronous belt pressing wheel 2-1265 is arranged outside the primary synchronous belt 2-1254 to ensure the stability of the transmission.

[0075] Please refer again to Figure 1 In this embodiment, the main body of the lifting cylinder 3-11 is fixedly connected with the rack bottom plate 1-1 through the fixing frame 6.

[0076] Please refer again to Figure 1 and Figure 11 、 Figure 12 In this embodiment, the material distribution unit 3 further comprises a material distribution push plate limiting mechanism 3-3, which comprises a front baffle 3-31, a rear fixed plate 3-32, and a thickness adjusting block 3-33. The rear fixed plate 3-32 is vertically upwardly fixed at the front end top of the rack bottom plate 1-1. A thickness adjusting block 3-33 is arranged between the left and right sides of the lower part of the front baffle 3-31 and the rear fixed plate 3-32. The thickness adjusting block 3-33 is detachably fixedly connected with the lower part of the front baffle 3-31 and the rear fixed plate 3-32. The lower part of the front baffle 3-31, the two thickness adjusting blocks 3-33, and the rear fixed plate 3-32 form a limiting passage (i.e., the passage in which the upper part of the material distribution push plate 3-12 is located) that is adapted to the material distribution push plate 3-12 and is through from top to bottom. Thus, the material distribution push plate 3-12 is guided and limited in upward and downward movement. By arranging the thickness adjusting block 3-33 and detachably fixing the thickness adjusting block 3-33 with the lower part of the front baffle 3-31 and the rear fixed plate 3-32, the thickness adjusting block 3-33 can be replaced according to the different specifications of the rotor balance block 4 to be distributed, so as to form a limiting passage that is adapted to the size of the rotor balance block 4 to be distributed. This is because the thickness and diameter of different specifications of the rotor balance block 4 are different. In order to better perform the material distribution and pushing function, the material distribution push plate 3-12 needs to be replaced with a size specification that is adapted to the different specifications of the rotor balance block 4. Therefore, the limiting passage needs to be adjusted accordingly to guide and limit the upward and downward movement of the material distribution push plate 3-12 more accurately.

[0077] Please refer again to Figure 1 and Figures 11 to 13As shown, in the embodiment, the material distribution temporary storage space 3-2 is formed by the rear block 3-22 with a top surface in the shape of a letter E and the upper part of the front baffle 3-31 being connected to each other, and the rear block 3-22 and the upper part of the front baffle 3-31 are detachably fixedly connected. The detachable fixed connection between the rear block 3-22 and the upper part of the front baffle 3-31 can facilitate replacement of the rear block 3-22 of a size suitable for the rotor balance weight 4 to be distributed, so as to ensure that the rear block 3-22 and the upper part of the front baffle 3-31 can form a material distribution temporary storage space 3-2 suitable for the size of the rotor balance weight 4 to be distributed.

[0078] As a preferred solution, in the embodiment, the top center of the front baffle 3-31 is symmetrically provided with a first U-shaped opening 3-311, and the top center of the rear block 3-22 is provided with a second U-shaped opening 3-221 corresponding to the first U-shaped opening 3-311. By providing the first U-shaped opening 3-311 and the second U-shaped opening 3-221, the robot can smoothly clamp the rotor balance weight 4 in the material distribution temporary storage space 3-2. Please refer to Figure 19 and Figure 21 as shown.

[0079] Please refer to Figure 1 and Figure 14 , Figure 15 As shown, in the embodiment, the material distribution unit 3 further comprises a material distribution product limiting mechanism 3-4, which comprises material distribution product baffles 3-41 located on the left and right sides of 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 temporary storage space 3-2 (please refer to Figure 21As shown), the product baffle front and rear position adjustment mechanism 3-42 includes a product baffle fixing block 3-421. The lower part of the product baffle fixing block 3-421 has an L-shaped notch 3-4211. A slider 3-422 is fixedly installed inside the L-shaped notch 3-4211. The slider 3-422 is slidably connected to a linear slide rail 3-423. The upper part of the product baffle fixing block 3-421 is fixedly connected to the outer rear end of the product baffle 3-41. The linear slide rail 3-423 is fixedly installed on the outer front end of the baffle plate 2-121. The vertical connecting plate 2-123 near the linear slide rail 3-423 is also fixedly installed on its top. A positioning seat 3-424 is fixedly provided. A height adjustment screw 3-425 is provided between the positioning seat 3-424 and the upper part of the product distribution baffle fixing block 3-421. A compression spring 3-426 is sleeved on the height adjustment screw 3-425 located between the positioning seat 3-424 and the product distribution baffle fixing block 3-421. The product distribution baffle 3-41 includes a horizontal part 3-411 and a vertical part 3-412 located above the front end of the horizontal part 3-411. The lower sides of the rear stop block 3-22 are respectively provided with downward-facing U-shaped channels 3-222 through which the horizontal parts 3-411 of the corresponding product distribution baffle 3-41 pass (see [link]). Figure 1 As shown), the vertical portions 3-412 of the two side distribution product baffles 3-41 are located on the left and right sides of the distribution temporary storage space 3-2, respectively, and the front end faces of the vertical portions 3-412 of the two side distribution product baffles 3-41 abut against the inner wall surface of the front baffle 3-31 (see [reference]). Figure 14 As shown and Figure 21 (As shown). The provided product limiting mechanism 3-4 can limit the rotor balance block 4 located in the product temporary storage space 3-2, ensuring that the robot can smoothly grip the rotor balance block 4 located in the product temporary storage space 3-2. The provided product baffle front-to-back position adjustment mechanism 3-42 can adjust the front-to-back position of the product baffle 3-41. Furthermore, the product baffle 3-41 is connected to the material channel width adjustment mechanism 2-12 (see [link]). Figure 7 As shown in the figure, it can change its left and right position as the material channel width adjustment mechanism 2-12 expands or contracts. Therefore, the material distribution product limiting mechanism 3-4 can play a precise limiting role for rotor balance blocks 4 of different specifications.

[0080] Please combine Figure 2 , Figure 3 , Figures 16 to 18 , Figure 20 and Figure 23As shown, in the embodiment, the material distribution unit 3 further comprises a material distribution product anti-falling mechanism 3-5, which comprises a fixed seat 3-51, a spring fixed seat 3-52 horizontally penetrating the center of the fixed seat 3-51, an extension spring 3-53 horizontally penetrating the center of the spring fixed seat 3-52, a U-shaped opening 3-521 with an opening facing backward arranged at the rear end of the spring fixed seat 3-52, a roller 3-54 fixedly arranged in the U-shaped opening 3-521, an extension spring compression block 3-55 fixedly connected to the front end of the fixed seat 3-51, the front end of the extension spring 3-53 is fixedly connected with the extension spring compression block 3-55, the rear end of the extension spring 3-53 abuts against the roller 3-54, and the rear end surface of the fixed seat 3-51 is connected with the front side surface of the front baffle 3-31, and the front baffle 3-31 is provided with a through hole 3-312 for the roller 3-54 and the front end of the spring fixed seat 3-52 to pass through. As a preferred solution, the top surface of the through hole 3-312 is substantially flush with the bottom surface 2-113 of the material channel bottom plate 2-11. In this way, when the lifting cylinder 3-11 fails to upwardly push the rotor balance block 4 located in the material distribution temporary storage space 3-2 due to failure, the roller 3-54 can be timely pushed into the space behind under the elastic force of the extension spring 3-53 to block the further falling of the falling rotor balance block 4.

[0081] As a preferred solution, in the embodiment, the front baffle 3-31 is provided with a material distribution initial position detection sensor 7 for sensing the arrival of the material distribution product to the top surface 3-121 of the material distribution push plate, and a material distribution terminal position detection sensor 8 for sensing the arrival of the material distribution product to the material distribution temporary storage space 3-2.

[0082] The operation of the device for automatically distributing a batch of rotor balance blocks is as follows:

[0083] Firstly, according to the size specification of the rotor balance block 4 to be fed, the width of the feeding channel 2-1 is adjusted to be suitable for the transverse dimension of the rotor balance block 4 to be fed, and the appropriate push block 2-21 and material distribution push plate 3-12 are selected, and the appropriate rear stop block 3-22 and thickness adjusting block 3-33 are selected so that the material distribution temporary storage space 3-2 and the limiting channel of the material distribution push plate 3-12 are suitable for the size specification of the rotor balance block 4 to be distributed, and the front and rear positions of the material distribution product baffle 3-41 are adjusted so that it can accurately limit the rotor balance block 4;

[0084] Then, the batch of rotor balance blocks 4 to be fed are put into the feeding channel 2-1 in a unified direction by artificial or mechanical hand, as shown in Figure 1 ;

[0085] Because 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, the top surface 2-111 of the channel bottom plate 2-11), when the rotor balance block 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 material distribution initial position detection sensor 7 (see Figs. 3 and 4), and 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 block 4 located on the top surface is pushed into the material distribution temporary storage space 3-2, at which time it will be detected by the material distribution termination position detection sensor 8 (see Figs. 3 and 4), and then the controller will make the robot (not shown in the figure) take away the rotor balance block 4 located in the material distribution temporary storage space 3-2. After the robot takes it away, 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, and then start the push driving assembly 2-22 to make the push block 2-21 move forward in a straight line, so as to push the rotor balance block 4 in the feeding channel 2-1 forward, until the next rotor balance block 4 reaches the top surface of the material distribution push plate, and then the lifting cylinder 3-11 is started again to rise, thereby driving the material distribution push plate 3-12 to move upward again, so that the current rotor balance block 4 located on the top surface is pushed into the material distribution temporary storage space 3-2 to be taken away by the robot, and the cycle is repeated. When the current batch of rotor balance blocks 4 in the feeding channel 2-1 are completely pushed away, because the front end of the push block 2-21 is not in contact with the rotor balance block 4 at this time, the extension spring 2-27 will be stretched to separate the sensor sensing sheet 2-29 located on the top of the second vertical fixed plate 2-233 from the material shortage detection sensor 2-28 located on the top of the first vertical fixed plate 2-232 (see Figs. 3 and 4), and the controller (not shown in the figure) will remind the feeding channel 2-1 to be replenished by monitoring the disconnection signal between the material shortage detection sensor 2-28 and the sensor sensing sheet 2-29. Figure 2 and Figure 3 When the current batch of rotor balance blocks 4 in the feeding channel 2-1 are completely pushed away, because the front end of the push block 2-21 is not in contact with the rotor balance block 4 at this time, the extension spring 2-27 will be stretched to separate the sensor sensing sheet 2-29 located on the top of the second vertical fixed plate 2-233 from the material shortage detection sensor 2-28 located on the top of the first vertical fixed plate 2-232 (see Figs. 3 and 4), and the controller (not shown in the figure) will remind the feeding channel 2-1 to be replenished by monitoring the disconnection signal between the material shortage detection sensor 2-28 and the sensor sensing sheet 2-29. Figure 20 When the current batch of rotor balance blocks 4 in the feeding channel 2-1 are completely pushed away, because the front end of the push block 2-21 is not in contact with the rotor balance block 4 at this time, the extension spring 2-27 will be stretched to separate the sensor sensing sheet 2-29 located on the top of the second vertical fixed plate 2-233 from the material shortage detection sensor 2-28 located on the top of the first vertical fixed plate 2-232 (see Figs. 3 and 4), and the controller (not shown in the figure) will remind the feeding channel 2-1 to be replenished by monitoring the disconnection signal between the material shortage detection sensor 2-28 and the sensor sensing sheet 2-29. Figure 22 When the current batch of rotor balance blocks 4 in the feeding channel 2-1 are completely pushed away, because the front end of the push block 2-21 is not in contact with the rotor balance block 4 at this time, the extension spring 2-27 will be stretched to separate the sensor sensing sheet 2-29 located on the top of the second vertical fixed plate 2-233 from the material shortage detection sensor 2-28 located on the top of the first vertical fixed plate 2-232 (see Figs. 3 and 4), and the controller (not shown in the figure) will remind the feeding channel 2-1 to be replenished by monitoring the disconnection signal between the material shortage detection sensor 2-28 and the sensor sensing sheet 2-29. Figure 23 When the current batch of rotor balance blocks 4 in the feeding channel 2-1 are completely pushed away, because the front end of the push block 2-21 is not in contact with the rotor balance block 4 at this time, the extension spring 2-27 will be stretched to separate the sensor sensing sheet 2-29 located on the top of the second vertical fixed plate 2-233 from the material shortage detection sensor 2-28 located on the top of the first vertical fixed plate 2-232 (see Figs. 3 and 4), and the controller (not shown in the figure) will remind the feeding channel 2-1 to be replenished by monitoring the disconnection signal between the material shortage detection sensor 2-28 and the sensor sensing sheet 2-29.

[0086] As can be seen from the above, the device of the present application can realize automatic batch separation of rotor balance blocks, and can realize automatic feeding of rotor balance blocks in cooperation with the robot. It not only effectively avoids the defects of high labor cost, high labor intensity, and low production efficiency of manual feeding, but also effectively avoids the risk of misplacing the direction of the rotor balance block, which leads to subsequent normal assembly operation. It has significant application value for realizing high automation of rotor assembly production.
