[0002] In the field of motor manufacturing, the gluing and assembly of rotor magnetic sheets is a crucial link, which directly affects the performance and life of the motor. The traditional gluing and assembly process of motor rotor magnetic sheets mostly relies on manual operation, which has problems such as uneven gluing, low pressing accuracy, and low production efficiency. Manual gluing is difficult to ensure the precise control of the amount of glue, and is easily affected by the skill level of the operator, resulting in uneven gluing results. At the same time, when manually pressing the magnetic sheets, it is difficult to ensure the precise alignment and uniform force between the magnetic sheets and the rotor mounting slots, which in turn affects the fixing effect of the magnetic sheets and the overall performance of the motor.

[0060] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0061] Embodiment 1:

[0062] like Figures 1 to 4 As shown, the present invention provides a motor rotor magnetic sheet gluing assembly mechanism, which mainly includes a push-pull assembly 4, a magnetic sheet pressing assembly 5 and a gluing assembly 6.

[0063] Combination Figures 1 to 4 As shown, the push-pull assembly 4 is arranged in parallel above the rotor 2. The rotor 2 is positioned on the positioning fixture 3 and the axis of the rotor 2 is arranged horizontally. The frame 7 includes an upper cross plate 72, and a pair of support plates 71 are fixed under the upper cross plate 72. The push-pull assembly 4 includes a cylinder 41 fixedly penetrated on the two support plates 71, and the cylinder 41 is parallel to the axis of the rotor 2. A movable plate 42 is fixed to the piston rod end of the cylinder 41, and a pair of guide slide rods 43 are slidably penetrated in the slide holes on the two support plates 71, and one end of the guide slide rod 43 is fixedly connected to the movable plate 42. The cylinder 41 drives the movable plate 42 by the extension and contraction of the piston rod, and the two guide slide rods 43 provide support and guidance for the movable plate 42 to ensure the movement accuracy of the movable plate 42.

[0064] A limiting bolt 44 opposite to the upper horizontal plate 72 is fixed on the movable plate 42 . Before the cylinder 41 retracts to the limit position, the limiting bolt 44 will abut against the upper horizontal plate 72 to limit the piston rod of the cylinder 41 .

[0065] Combination Figures 1 to 4 As shown, the glue coating assembly 6 is arranged parallel to the rotor 2. The glue coating assembly 6 includes a cylinder 61 parallel to the axis of the rotor 2, and the cylinder 61 slides through the sliding holes on the two support plates 71. The middle of the cylinder 61 has a step 67, and the floating spring 66 is sleeved on the cylinder 61. Figure 2As shown, the floating spring 66 and the cylinder bottom 611 of the cylinder 61 are arranged on both sides of the rear support plate 71, and the two ends of the floating spring 66 are respectively against the rear support plate 71 and the step 67. Under the thrust of the floating spring 66, the cylinder bottom 611 is tightly attached to the rear side of the support plate 71, thereby realizing the floating positioning of the cylinder bottom 611.

[0066] The hollow piston rod 62 is installed in the cylinder 61, and the inner cavity of the hollow piston rod 62 is connected to the inner cavity of the cylinder 61. The end of the hollow piston rod 62 away from the cylinder 61 is fixedly connected to the one-way glue head 63, and the one-way glue head 63 is connected to the inner cavity of the hollow piston rod 62. The one-way glue head 63 is provided with a glue hose that cooperates with the glue storage groove 22 on the rotor 2. A one-way valve is provided in the one-way glue head 63 to ensure that the glue can only flow out in one direction. The one-way glue head 63 is fixedly connected to the moving plate 42. Driven by the moving plate 42, the one-way glue head 63 and the hollow piston rod 62 can move repeatedly.

[0067] The cylinder bottom 611 of the cylinder 61 is connected to the glue tank through a one-way liquid inlet valve 64, and the cylinder bottom 611 is further connected to the glue tank through a flow-adjustable valve 65. When the hollow piston rod 62 extends out of the cylinder 61, the glue in the glue tank is sucked into the cylinder 61 through the one-way liquid inlet valve 64 and the valve 65; when the hollow piston rod 62 retracts into the cylinder 61, the glue in the cylinder 61 is squeezed out from the one-way glue outlet head 63, and part of the glue will flow back to the glue tank from the valve 65; therefore, by adjusting the valve 65, the amount of glue squeezed out from the one-way glue outlet head 63 can be controlled to adapt to different rotors 2.

[0068] Combination Figures 1 to 4 As shown, the magnetic sheet pressing assembly 5 includes a support frame 51 fixedly connected to the movable plate 42. The pull rod 52 is slidably mounted on the support frame 51. An adjusting bolt 53 is connected to the end of the support frame 51 away from the push-pull assembly 4, and the adjusting bolt 53 abuts against one side of the pull rod 52. When in use, the position of the pull rod 52 can be adjusted by screwing in or out the adjusting bolt 53 to accommodate magnetic sheets 1 of different lengths. When the cylinder 41 drives the hollow piston rod 62 to retract the cylinder barrel 61, the glue in the cylinder barrel 61 is squeezed out from the one-way glue outlet head 63 to the glue storage groove 22; in this process, the cylinder 41 will simultaneously drive the support frame 51 to move toward the rotor 2, and the lower end of the pull rod 52 gradually presses the magnetic sheet 1 into the magnetic sheet mounting groove 21 on the rotor 2, so as to realize the glue coating and the pressing of the magnetic sheet 1 at the same time.

[0069] Embodiment 2:

[0070] Based on the above embodiment 1, Figures 1 to 4 As shown, a receiving assembly 54 cooperating with the magnetic sheet 1 is provided at the lower end of the pull rod 52 to improve the press-fitting accuracy of the magnetic sheet 1 .

[0071] The receiving assembly 54 includes an abutment block 541 fixed to the lower end of the pull rod 52 facing the push-pull assembly 4, and the abutment block 541 is mainly used to push the magnetic sheet 1. There is an avoidance groove 542 below the abutment block 541, and the receiving plate 543 is slidably installed in the avoidance groove 542 on the lower side of the abutment block 541. The tension spring 545 is connected between the receiving plate 543 and the lower end of the pull rod 52, and is used to pull the receiving plate 543 out of the avoidance groove 542. The receiving plate 543 is provided with a receiving stop 544 that cooperates with the magnetic sheet 1 on the side facing the push-pull assembly 4, and the receiving stop 544 has a slope for guiding the magnetic sheet 1. Figure 3 As shown, when there is no external force, under the action of the tension of the tension spring 545, the receiving stop 544 of the receiving plate 543 extends out of the avoidance groove 542 to receive the magnetic sheet 1. However, when the receiving plate 543 is subjected to a certain external force opposite to the tension of the tension spring 545, the receiving stop 544 of the receiving plate 543 can be completely retracted into the avoidance groove 542, so that the abutment block 541 contacts the magnetic sheet 1.

[0072] Working process:

[0073] by Figure 2 This is the initial state. At this time, the cylinder 61 has already sucked the glue liquid. Put the magnetic sheet 1 into Figure 2 The cylinder 41 begins to slowly retract, the movable plate 42 drives the one-way glue head 63 and the hollow piston rod 62 to retract, and at the same time pulls the support frame 51 and the pull rod 52; the glue in the cylinder 61 is gradually squeezed out from the one-way glue head 63 into the glue storage groove 22, and the pull rod 52 gradually presses the magnetic sheet 1 into the magnetic sheet installation groove 21;

[0074] arrive Figure 5 When the position is shown, the hollow piston rod 62 has been completely retracted into the cylinder 61, and no more glue will be squeezed out from the one-way glue head 63, and the one-way glue head 63 just reaches the end of the glue storage groove 22; at this time, the cylinder 41 continues to slowly retract, and the moving plate 42 drives the hollow piston rod 62 and the cylinder 61 to compress the floating spring 66 until the one-way glue head 63 is separated from the magnetic sheet installation groove 21; in this process, the pull rod 52 continues to move to completely press the magnetic sheet 1 into the magnetic sheet installation groove 21;

[0075] arrive Figure 6 In the position shown, the magnetic sheet 1 has been completely pressed into the magnetic sheet installation groove 21, and the cylinder 41 has retracted into position; in addition, the receiving plate 543 is now against one end of the rotor 2, and is then squeezed back into the avoidance groove 542 to avoid hindering the rotation of the rotor 2;

[0076] Then, the rotor 2 is rotated to another magnetic sheet installation slot 21 position; the cylinder 41 begins to extend, and the cylinder 61 gradually absorbs the glue until Figure 2 The position shown in the figure returns to the initial state, at which time, the installation of the next magnetic disk 1 begins.

[0077] Embodiment three:

[0078] Based on the above embodiment 1 or embodiment 2, Figures 1 to 4 As shown, this embodiment provides a positioning tool 3 for positioning the rotor 2 and controlling the rotor 2 to rotate around the axis of the rotor 2. Figure 1 As shown, the circumferential surface of the rotor 2 is provided with evenly distributed magnetic sheet installation grooves 21, the bottom of the magnetic sheet installation grooves 21 is provided with a glue storage groove 22, and the magnetic sheet installation grooves 21 are provided with a section of cutout 23 so that the magnetic sheet 1 can be smoothly placed during processing.

[0079] Recombination Figure 7 As shown, the positioning fixture 3 includes a support seat 31 fixed on the lower cross plate 73, and a support shaft 32 is rotatably mounted on the support seat 31. One end of the support shaft 32 is connected to a stepper motor, and the rotation angle of the support shaft 32 is accurately controlled by the stepper motor. An adjustment sleeve 33 and a positioning sleeve 37 are mounted on the support shaft 32. The cross-section of the positioning sleeve 37 and the support shaft 32 is a polygon, which prevents the positioning sleeve 37 and the support shaft 32 from rotating relative to each other. The positioning sleeve 37 is mounted in the axial hole of the rotor 2, and the convex strip 371 on the surface of the positioning sleeve 37 cooperates with the keyway in the axial hole of the rotor 2 to prevent the positioning sleeve 37 and the rotor 2 from rotating relative to each other. The adjustment sleeve 33 is located between the support seat 31 and the rotor 2. The use of adjustment sleeves 33 of different lengths can adjust the relative position of the rotor 2 and the upper glue coating component 6.

[0080] The ejector pin 34 is rotatably mounted on the sliding seat 35, and the sliding seat 35 is slidably connected to the lower cross plate 73. A positioning bolt 36 is mounted on the sliding seat 35 and abuts against the lower cross plate 73 to limit the relative position of the sliding seat 35 and the lower cross plate 73. When in use, the ejector pin 34 is pressed against the end of the rotor 2 away from the support shaft 32 to achieve stable support of the rotor 2.
