[0018] Refer to Figures 1 to 4 As shown in the figure, the utility model provides an automatic rotor magnet steel embedding device, including: a magnet steel embedding machine 1, a magnet steel loading tray 2 and an embedding pressure plate 3. The upper end of the table surface of the magnet steel embedding machine 1 is connected with a magnet steel loading tray 2 and an embedding pressure plate 3 through a lifting platform 4.

[0019] A central column 14 is welded in the middle of the upper table surface of the magnet steel embedding machine 1. Limit insertion plates 5 are distributed on the outer side of the central column 14. A pressure plate 51 is fixedly connected to the lower end surface of the limit insertion plate 5 by screwing. The lower end of the pressure plate 51 is connected to the groove wall of the moving bottom plate 52 through a spring 55. The middle of the moving bottom plate 52 is connected with a lead screw 53 through a driving block 57. The lead screw 53 is installed on the inner side wall of the magnet steel embedding machine 1. The lower end of the lead screw 53 is axially connected with a motor 2 54. A pressure sensor 56 is installed on the upper groove surface of the moving bottom plate 52.

[0020] When carrying out the rotor magnet steel embedding process, first, the magnet steel sheet is sent to the groove of the magnet steel loading tray 2 of the magnet steel sheet by a feeding manipulator for adsorption, and then the rotor is inserted into the central column 14 on the upper table surface of the steel embedding machine 1, so that the limit insertion plate 5 is inserted into the rotor magnetic groove. The magnet steel loading tray 2 is pressed down to fit on the surface of the rotor. At the same time, the embedding pressure plate 3 is pressed down to push the magnet steel sheet into the rotor magnetic groove. The pressed magnet steel sheet pushes the limit insertion plate 5 downward to squeeze the spring 55, so that the pressure plate 51 contacts the pressure sensor 56, senses the downward pressure of the magnet steel sheet. When the downward pressure of the magnet steel sheet reaches a preset constant value, the moving bottom plate 52 starts to descend, and the descending speed is the same as the downward pressing speed of the embedding pressure plate 3, so as to maintain the constancy of the pressure when the magnet steel sheet moves until the moving bottom plate 52 moves down to the lowest end. At this time, the magnet steel sheet is embedded in place, the embedding pressure plate 3 and the magnet steel loading tray 2 are lifted, and the embedded rotor can be taken out.

[0021] In this embodiment, a feeding slide 11 is installed on the surface of the frame of the magnet steel embedding machine 1; and a feeding manipulator is slidably connected to the surface of the feeding slide 11. The front surface of the frame of the magnet steel embedding machine 1 is equipped with a lifting platform 4.

[0022] As a preferred embodiment, the feeding slide table 11 facilitates the movement of the feeding manipulator in and out, enabling the feeding manipulator to send the rotor and the magnetic steel sheets to the table of the magnetic steel inserting machine 1 and the slots of the magnetic steel feeding tray 2. Meanwhile, after the inserting is completed, the inserted rotor is moved to the next processing equipment by the manipulator on the other side. The lifting platform 4 facilitates driving the magnetic steel feeding tray 2 and the inserting pressure plate 3 to move up and down.

[0023] In this embodiment, a central control box 12 is fixed on the right side of the lifting platform 4, an alarm 13 is installed at the lower end of the central control box 12, and a first motor 41 is fixed on the upper surface of the lifting platform 4.

[0024] As a preferred embodiment, the central control box 12 facilitates controlling the electrical equipment used for the automatic insertion of the rotor and the magnetic steel. The alarm 13 facilitates prompting the alarm signal for the failure of mechanical connection and the insertion not in place, pausing the inserting process, and facilitating the operator to promptly repair the magnetic steel inserting machine 1.

[0025] In this embodiment, the lower end of the first motor 41 is connected to the magnetic steel feeding tray 2 through a rotating rod 42, and the lower end of the lifting platform 4 is connected to the inserting pressure plate 3 through an electric push rod 31; and the inserting pressure plate 3 is located above the magnetic steel feeding tray 2, and a rubber pad 32 is adhered to the lower surface of the inserting pressure plate 3. A vacuum suction port 22 is arranged on the inner groove surface of the magnetic steel feeding tray 2; and a magnetic steel sheet is adsorbed on the surface of the vacuum suction port 22, and the vacuum suction port 22 is connected to a vacuum pump through a vacuum tube 21.

[0026] As a preferred embodiment, the first motor 41 drives the magnetic steel feeding tray 2 to rotate at a fixed angle through the rotating rod 42, so that the inner groove of the magnetic steel feeding tray 2 rotates and moves above the feeding manipulator, facilitating adsorbing the magnetic steel sheet clamped by the feeding manipulator and facilitating loading and inserting the magnetic steel sheet into the slot of the magnetic steel feeding tray 2. The inserting pressure plate 3 presses down to push the magnetic steel sheet in the slot of the magnetic steel feeding tray 2, so that the magnetic steel sheet is inserted into the magnetic slot of the rotor. The vacuum suction port 22 facilitates the magnetic steel feeding tray 2 to firmly adsorb the magnetic steel sheet inserted in the slot.

[0027] In this embodiment, a positioner 15 is embedded and fixed on the surface of the central column 14, the lower end of the lead screw 53 is axially connected to a second motor 54, and the pressure sensor 56 is located at the lower end of the pressing plate 51.

[0028] As a preferred embodiment, the positioner 15 facilitates positioning the loading position of the rotor, enabling the rotor to be inserted at the central column 14, and facilitating the magnetic insertion processing of the rotor. The second motor 54 controls the rotation speed of the lead screw 53, so that the driving block 57 converts the rotational motion of the lead screw 53 into a linear motion, driving the moving bottom plate 52 to descend, and enabling the limit insertion plate 5 to descend and move out of the rotor magnetic slot.

[0029] In this embodiment, the embedded pressing plate 3, the limiting insertion plate 5, the pressing plate 51, the spring 55, the moving bottom plate 52, the lead screw 53 and the pressure sensor 56 constitute a constant-pressure embedding mechanism.

[0030] As a preferred implementation manner, the constant-pressure embedding mechanism is convenient for accurately ensuring the automatic embedding of the rotor and the permanent magnet in place, effectively avoiding the situation of the permanent magnet shifting or not being inserted in place, facilitating the maintenance of the stability of the permanent magnet embedding force, preventing the permanent magnet from breaking due to excessive embedding force, and improving the embedding effect of the rotor permanent magnet.
