[0015] The brushless motor rotor press-fit assembly device includes an assembly plate 1, a magnetic sheet press-fit assembly 3, an adhesive application assembly 2, and a final assembly 4 (see the instruction manual appendix). Figure 1 , 2 and 3).

[0016] The center of assembly plate 1 is fitted with adhesive application component 2 (see instruction manual appendix). Figure 1 , 2 and 3).

[0017] The glue application assembly 2 includes an indexing plate 6, a driver 12, a glue dispensing head 10, and a rotating component 7 (see the attached instruction manual). Figure 4 and 8 ).

[0018] The indexing plate 1 is mounted on an indexing motor 5, and an indexing plate 6 is mounted on the indexing plate 6. Multiple rotating components 7 are evenly installed on the indexing plate 6 (see the instruction manual appendix). Figure 8 When the indexing plate 6 is working, it can drive the rotating component 7 to rotate intermittently at a fixed angle.

[0019] Rotating component 7 includes two sets of rotating positioning seats 13, a passive coupling chuck 16, and a drive belt 14 (see the instruction manual appendix). Figure 10 The indexing plate 6 is equipped with two sets of rotary positioning seats 13; the lower ends of the two sets of rotary positioning seats 13 extend below the indexing plate 6 and are connected to each other via a drive belt 14 and a pulley 15; one set of rotary positioning seats 13 extends below the indexing plate 6 and is equipped with a driven coupling chuck 16 (see the instruction manual appendix). Figure 10The purpose of this rotating component 7 is to enable the passive coupling chuck 16 to rotate synchronously via the transmission belt 14 and pulley 15 when it is subjected to force.

[0020] The rotary positioning seat 13 is provided with a positioning countersunk hole (not shown in the attached diagram of the instruction manual); multiple locking plungers 17 are evenly installed on the rotary positioning seat 13 around the positioning countersunk hole (see attached diagram of the instruction manual). Figure 11 The purpose of this rotating positioning seat 13 is to allow the locking plunger 17 to press the pressure sleeve 37 from the side after the component pressure sleeve 37 is placed on the rotating positioning seat 13 through the positioning countersunk hole during operation, so that the rotating positioning seat 13 can drive the pressure sleeve 37 to rotate synchronously when it rotates.

[0021] A lifting seat 9 is mounted above the indexing plate 6 via a bracket 8; two sets of dispensing heads 10 are mounted on the lifting seat 9; a control screw 11 is mounted on the bracket 8 via a motor; the control screw 11 is connected to the lifting seat 9 (see the instruction manual appendix). Figure 8 When the motor is working, the lifting seat 9 can be driven by the control screw 11 to move the glue injection head 10 up and down.

[0022] The drive unit 12 is mounted on the mounting plate 1 below the indexing plate 6 (see the instruction manual appendix). Figure 8 The drive unit 12 includes an active coupling chuck 21, a lifting plate 19, a lifting cylinder 18, and a rotary motor 20 (see the attached instruction manual). Figure 9 Below the indexing plate 6, a lifting plate 19 is mounted via a lifting cylinder 18; a drive coupling chuck 21 is mounted on the lifting plate 19 via a rotary motor 20. During operation, the lifting plate 19 moves upward, causing the drive coupling chuck 21 to engage with the driven coupling chuck 16. When the rotary motor 20 drives the drive coupling chuck 21 to rotate, the drive coupling chuck 21 can then drive the two sets of rotating positioning seats 13 to rotate synchronously via the driven coupling chuck 16, the transmission belt 14, and the pulley 15. The magnetic sheet pressing assembly 3 is mounted on the mounting plate 1 on one side of the adhesive application assembly 2 (see the instruction manual appendix). Figure 1 , 2 (and 3). The magnetic sheet pressing assembly 3 includes a pressing positioning sleeve 22, a lifting cylinder 25, a lifting frame 26, a driving pressure head 30, a rotating shaft 27, a lifting cylinder 23, and a lifting sleeve 24.

[0023] An extrusion positioning sleeve 22 is fixedly mounted on the assembly plate 1; the interior of the extrusion positioning sleeve 22 is evenly provided with multiple arc-shaped protrusions 33 (see the instruction manual appendix). Figure 7 During operation, when the motor rotor with the pre-installed magnetic sheet rotates inside the compression positioning sleeve 22, the compression positioning sleeve 22 can compress the magnetic sheet through the arc-shaped protrusion 33, causing it to be pressed into the inside of the motor rotor.

[0024] Below the compression positioning sleeve 22, there is a lifting cylinder 23 and a lifting rotating sleeve 24 (see the instruction manual appendix). Figure 6 The lifting sleeve 24 can rotate freely when subjected to force.

[0025] A lifting frame 26 is mounted above the extrusion positioning sleeve 22 via a lifting cylinder 25; a rotating shaft 27 is mounted on the lifting frame 26 via a bearing seat; the upper end of the rotating shaft 27 is connected to a drive motor 29 mounted on the lifting frame 26 via a transmission belt 28. A drive pressure head 30 is slidably mounted on the lower end of the rotating shaft 27 via a spline groove; a clamping ring 38 is mounted on the lifting frame 26 outside the drive pressure head 30 (see the attached instruction manual). Figure 5 and 6 A buffer spring 31 is provided between the upper end of the driving pressure head 30 and the rotating shaft 27 (see the instruction manual appendix). Figure 6 When the drive motor 29 is working, it can drive the drive pressure head 30 to rotate synchronously through the transmission belt 28 and the rotating shaft 27.

[0026] The purpose of setting the buffer spring 31 is to enable the drive pressure head 30 to overcome the elastic force of the buffer spring 31 and move upward when it is pressed, so that the drive pressure head 30 can be inserted and connected to the end of the electronic rotor under the action of the elastic force during operation.

[0027] The lower end of the drive pressure head 30 is provided with multiple insertion protrusions 32 (see the instruction manual). Figure 5 During operation, the drive pressure head 30 can be inserted into the hole at the end of the motor rotor via the insertion protrusion 32 to connect with it. In this way, when the drive pressure head 30 rotates, it can drive the motor rotor to rotate synchronously.

[0028] On the other side of the adhesive application assembly 2, the assembly plate 1 is fitted with the final assembly 4 (see the instruction manual appendix). Figure 1 , 2 (and 3). The final assembly 4 includes a clamping sleeve 34, a pressing cylinder 35, and a positioning sleeve 36; the positioning sleeve 36 is fixedly mounted on the assembly plate 1; the clamping sleeve 34 is mounted above the positioning sleeve 36 via the pressing cylinder 35 (see the appendix of the instruction manual). Figure 12 ).

[0029] In operation, the brushless motor rotor pressing and fitting device first manually places the brushless motor rotor, pre-loaded with magnetic plates, into the pressing and positioning sleeve 22. Then, the lifting cylinder 23 drives the lifting sleeve 24 to lift a certain distance, causing the brushless motor rotor to move upwards a certain distance. Afterwards, the lifting cylinder 25, through the lifting frame 26, drives the driving pressure head 30 downwards, allowing it to insert into the hole at the end of the motor rotor via the insertion protrusion 32, connecting with it. At this time, the clamping ring 38 presses and fixes the pressing and positioning sleeve 22.

[0030] After the above steps are completed, the drive motor 29 drives the drive pressure head 30 to rotate via the transmission belt 28 and the rotating shaft 27. During the rotation of the drive pressure head 30, the motor rotor can be driven to rotate synchronously with the assistance of the lifting sleeve 24. During the rotation of the motor rotor, the pressing positioning sleeve 22 can press the magnetic sheet through the arc-shaped protrusion 33 to press it into the inside of the motor rotor. Subsequently, the drive pressure head 30 drives the motor rotor to reverse and reset, and then the drive pressure head 30 moves upward to reset, and the lifting sleeve 24 moves downward to reset. At this point, the magnetic sheet pressing assembly 3 has completed the pressing work of the brushless motor rotor magnetic sheet.

[0031] When the magnetic sheet pressing assembly 3 is working, the pressing sleeve 37 to be coated with glue is placed on the rotating positioning seat 13 of the glue coating assembly 2. Then the indexing plate 6 rotates one position so that the rotating component 7 with the pressing sleeve 37 is rotated to correspond with the glue injection head 10.

[0032] When the pressure sleeve 37 aligns with the dispensing head 10, the lifting cylinder 18 of the driver 12 drives the lifting plate 19 to move upward, causing the active coupling chuck 21 to engage with the passive coupling chuck 16. Then, the rotary motor 20 drives the active coupling chuck 21 to rotate. When the active coupling chuck 21 rotates, it can drive the two sets of rotating positioning seats 13 and the pressure sleeve 37 to rotate synchronously via the passive coupling chuck 16, the transmission belt 14, and the pulley 15.

[0033] During the rotation of the pressure sleeve 37, the control screw 11 drives the lifting seat 9 to move down, so that the glue injection head 10 moves down into the inside of the pressure sleeve 37, so that the rotating pressure sleeve 37 can be reset after completing the glue application.

[0034] After the above actions are completed, the active coupling chuck 21 moves down to reset. At this point, the glue application assembly 2 has completed the glue application work on the pressure sleeve 37.

[0035] After the gluing assembly 2 completes the gluing of the pressure sleeve 37, it places the glued pressure sleeve 37 onto the positioning sleeve 36 of the assembly assembly 4. The brushless motor rotor, after the magnetic sheet pressing work is completed, is placed inside the pressure sleeve 37. Then, the pressing cylinder 35 drives the pressing sleeve 34 to move downward, so that it, with the cooperation of the positioning sleeve 36, presses the brushless motor rotor and the pressure sleeve 37 tightly and holds the pressure for a period of time. At this point, the brushless motor rotor pressing and assembly device has completed the assembly of the pressure sleeve. Then, the assembled motor rotor and pressure sleeve 37 are removed, and the assembly device can enter the next working cycle.

[0036] This brushless motor rotor pressing and assembly device has a compact structure and ingenious design. It can mechanize the pressing of magnetic sheets and the application of adhesive to the pressing sleeve, thereby solving the problem of low work efficiency in the existing installation method of brushless motor rotor pressing sleeve. It is particularly suitable for the needs of brushless motor rotor pressing and assembly.
