[0023] Example:

[0024] Reference Figure 1-Figure 4A brushless motor rotor assembly platform includes a base 1, a vertical plate 101 is fixedly arranged on the base 1, a sleeve 2 is rotatably arranged on the vertical plate 101, and a first motor 201 for driving the sleeve 2 to rotate is fixedly arranged on the vertical plate 101, a rotor body 7 is installed in the sleeve 2, wherein a positioning shaft 202 is coaxially fixedly arranged in the sleeve 2, and a positioning hole 701 corresponding to the positioning shaft 202 is coaxially opened on the rotor body 7, which can improve the installation accuracy of the rotor body 7, and then improve the installation accuracy of the magnetic steel block 8. A support seat 5 is slidably arranged on the base 1, a discharge plate 501 is fixedly arranged on the top of the support seat 5, a magnetic steel block 8 is installed on the discharge plate 501, and a plurality of groups of mounting grooves 702 for mounting the magnetic steel block 8 are evenly arranged on the rotor body 7, and at least two groups, preferably eight groups, of the mounting grooves 702 are arranged, and the end surface at the bottom of the topmost mounting groove 702 is lower than the top end surface of the discharge plate 501, and the height range between the two is 2mm-4mm, preferably 2mm, on the one hand, it is convenient for the magnetic steel block 8 to slide into the mounting groove 702, and on the other hand, during the sliding process, it can avoid pushing the glue at the bottom of the magnetic steel block 8 to one end of the magnetic steel block 8, thereby improving the fixing effect between the magnetic steel block 8 and the mounting groove 702; on the end of the discharge plate 501 close to the sleeve 2 A glue storage box 4 is fixedly arranged, and a glue coating roller 401 is rotatably arranged in the glue storage box 4. A third motor for driving the glue coating roller 401 to rotate is fixedly arranged on the outer wall of the glue storage box 4, and the end of the glue coating roller 401 away from the glue storage box 4 is pressed against the bottom of the magnetic steel block 8. When in use, when the magnetic steel block 8 slides into the mounting groove 702 at the top, the magnetic steel block 8 will slide from the top of the glue coating roller 401. During this process, glue can be evenly applied to the bottom of the magnetic steel block 8, and the end face at the bottom of the top mounting groove 702 is lower than the top end face of the discharge plate 501, which can prevent the glue from being pushed toward one end of the magnetic steel block 8 during the sliding process of the magnetic steel block 8, thereby improving the fixing effect and preventing the glue from dripping into the sleeve 2, thereby improving the cleaning effect inside the sleeve 2.

[0025] When in use, by applying glue to the bottom of the magnetic steel block 8 when installing the magnetic steel block 8 on the rotor body 7, it is possible to prevent glue from dripping, resulting in a reduction in the amount of glue and affecting the fixing effect. In addition, the end surface at the bottom of the topmost mounting groove 702 is lower than the top end surface of the discharge plate 501, which can prevent the magnetic steel block 8 from being pushed toward one end of the magnetic steel block 8 during the sliding process, thereby improving the fixing effect. By slidingly setting a pressing block 301 in the sleeve 2, and slidingly setting a connecting plate 3 fixedly connected to the pressing block 301 on the outer wall of the sleeve 2, on the one hand, through the pressing Block 301 can drive the rotor body 7 to rotate with the sleeve 2, which is convenient for assembling the magnetic steel block 8. On the other hand, the magnetic steel block 8 can be tightly fitted with the inner bottom of the installation groove 702 to improve the fixing quality. In addition, an arc block 103 is fixedly arranged on the vertical plate 101, and a sliding plate 302 is fixedly arranged on the connecting plate 3, so that the connecting plate 3 at the top can be raised to a certain height, so that the pressing block 301 is close to the inner wall of the sleeve 2, which can avoid applying pressure to the magnetic steel block 8 during the sliding process of the magnetic steel block 8, causing the glue to be pushed to one end, thereby further improving the fixing effect.

[0026] Reference Figure 1 , Figure 2 and Figure 4 , multiple groups of pressing blocks 301 are evenly and slidably arranged in the sleeve 2, and at least two groups of pressing blocks 301 are arranged. Here, we arrange the pressing blocks 301 to be the same in number as the mounting grooves 702, that is, the multiple groups of pressing blocks 301 correspond to the mounting grooves 702 one by one, and the two side surfaces of the pressing blocks 301 are respectively fitted with the two side surfaces of the inner wall of the corresponding mounting grooves 702. When in use, by fitting the two side surfaces of the pressing blocks 301 with the two side edges of the mounting grooves 702, when the sleeve 2 rotates, the pressing blocks 301 can drive the rotor body 7 to rotate together, which is convenient for assembling the magnetic steel block 8 and improving the use effect.

[0027] Reference Figure 1 , Figure 2 and Figure 4 , multiple groups of connecting plates 3 are evenly and slidably arranged on the outer wall of the sleeve 2, and the number of connecting plates 3 corresponds to the pressing block 301 one by one, and the multiple groups of connecting plates 3 are fixedly connected to the corresponding pressing block 301 through the connecting shaft 303, that is, two groups of symmetrically distributed connecting shafts 303 are fixedly arranged on the connecting plate 3, and one end of the connecting shaft 303 extending into the sleeve 2 is fixedly connected to the corresponding pressing block 301, and a spring 304 is sleeved on the connecting shaft 303, and the two ends of the spring 304 are respectively against the inner wall of the sleeve 2 and the pressing block 301, and the end surface of the pressing block 301 away from the connecting shaft 303 is against the top of the magnetic steel block 8. When in use, after the magnetic steel block 8 is installed in place, the sleeve 2 rotates a certain angle. During the rotation process, the bottom of the pressing block 301 can be against the top of the magnetic steel block 8 under the elastic force of the spring 304, so that the magnetic steel block 8 can be pressed tightly in the current installation groove 702, thereby improving the fixing effect.

[0028] Reference Figure 1 and Figure 4 , an arc block 103 is fixedly arranged on the vertical plate 101, and a sliding plate 302 is fixedly arranged on one end of the multiple groups of connecting plates 3 close to the vertical plate 101, so that the top of the arc block 103 is butted against the bottom end face of the sliding plate 302 currently at the top. When in use, when the sleeve 2 rotates a certain angle, the sliding plate 302 originally at the top slides off the arc block 103. At this time, the original pressing block 301 can press the magnetic steel block 8 into the mounting groove 702, and the sliding plate 302 at the top at this time will slide to the top of the arc block 103. In this process, the connecting plate 3 and the pressing block 301 at the top will rise to a certain height, so that the bottom end face of the pressing block 301 is away from the top end face of the magnetic steel block 8, which can avoid the pressing block 301 from applying pressure to the magnetic steel block 8 when the magnetic steel block 8 slides into the mounting groove 702, causing the glue at the bottom of the magnetic steel block 8 to be pushed to one end, affecting the fixing effect.

[0029] Reference Figure 1 and Figure 2 A fixing plate 102 is fixedly provided on the base 1. We symmetrically set two groups of fixing plates 102. A screw 6 is rotatably provided between the two groups of fixing plates 102. The end of the support seat 5 away from the discharge plate 501 is threadedly connected to the screw 6, and the bottom of the support seat 5 is abutted against the top of the base 1. This can ensure the reliable sliding of the support seat 5 and prevent it from flipping over and affecting normal use. A second motor 601 for driving the screw 6 to rotate is fixedly provided on one of the groups of fixing plates 102. When in use, the second motor 601 drives the screw 6 to rotate, so as to drive the support seat 5 to approach or move away from the sleeve 2, which is convenient for the assembly of the magnetic steel block 8, and convenient for installing the rotor body 7 into the sleeve 2 or removing it from the sleeve 2, thereby improving the use effect.

[0030] Reference Figure 2 and Figure 3Two sets of guide plates 502 are fixedly arranged on the discharge plate 501. The two sets of guide plates 502 are symmetrically arranged and extend all the way to the top of the glue storage box 4, so that the two side surfaces of the magnetic steel block 8 are respectively against the inner walls of the corresponding guide plates 502, which can ensure the reliable sliding of the magnetic steel block 8 and prevent the magnetic steel block 8 from being deflected and affecting the assembly effect. A push plate is slidably arranged between the two sets of guide plates 502, and one end of the push plate is against the magnetic steel block 8. A clamping plate is fixedly arranged on the top of the push plate, and the top of the magnetic steel block 8 close to the push plate is against the inner bottom of the clamping plate. This can prevent the magnetic steel block 8 from sliding into the installation groove 702 when the magnetic steel block 8 is pushed. The length of the end close to the installation groove 702 is greater than the length close to the push plate end when the glue coating roller 401 is used as the dividing line, so that the magnetic steel block 8 is subjected to unbalanced force, resulting in the end close to the push plate being tilted upward. When the magnetic steel block 8 continues to slide into the installation groove 702, the glue is easily pushed to One end, and it also affects the gluing effect of the glue coating roller 401. A cylinder 503 for driving the push plate to slide is fixedly arranged on the discharge plate 501. When in use, the magnetic steel block 8 is placed between the two sets of guide plates 502, so that one end of the magnetic steel block 8 is against the push plate and is under the card plate, and then the cylinder 503 is started to push the magnetic steel block 8 to slide into the installation groove 702 at the top. During this process, the glue coating roller 401 can apply glue to the bottom of the magnetic steel block 8. When the magnetic steel block 8 completely slides over the glue coating roller 401, the magnetic steel block 8 will fall into the installation groove 702. At this time, the cylinder 503 continues to push the magnetic steel block 8 a certain distance, so that the end of the magnetic steel block 8 away from the push plate is against the inner wall of the sleeve 2. At this time, the current magnetic steel block 8 is installed, and then the sleeve 2 is rotated a certain angle, and the above process is repeated. Another magnetic steel block 8 can be installed in the next installation groove 702 to improve the use effect.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
