Description

Technical Field

[0001] This application relates to the field of motor assembly technology, and in particular to an automatic assembly and dispensing equipment for magnetic steel sheets. Background Technology

[0002] The magnetic steel sheet is the core permanent magnet material of the motor rotor, and it together with the rotor core constitutes the rotor part of the motor.

[0003] Currently, there are two main methods for mounting magnets and rotor cores: surface mounting and embedded mounting. Embedded mounting involves machining magnet slots or holes into the rotor core, inserting the magnets into these slots or holes to assemble the magnets and rotor core. To improve the connection strength between the magnets and rotor core, adhesive is usually applied to the magnet slots. Because the magnets are relatively small and adjacent magnets are often attracted together, current assembly methods involve manually removing each magnet individually and inserting it into the magnet slot, resulting in low overall assembly efficiency. Summary of the Invention

[0004] To improve the assembly efficiency of magnet sheets and rotor cores, this application provides an automatic assembly and dispensing device for magnet sheets.

[0005] This application provides an automatic assembly and dispensing equipment for magnetic steel sheets, which adopts the following technical solution: An automatic assembly and dispensing device for magnetic steel sheets includes an assembly bracket, a positioning and placement seat, a rotation mechanism disposed on the assembly bracket and used to drive the positioning and placement seat to rotate, a transfer mechanism for driving the positioning and placement seat to move horizontally, a dispensing mechanism disposed at one end of the rotation mechanism, and a pressing mechanism disposed at the other end of the transfer mechanism and used to press multiple sets of magnetic steel sheets simultaneously.

[0006] By adopting the above technical solution, the assembly process of magnet sheets and rotor core is automated, which can avoid manual assembly, improve assembly efficiency, and simultaneously press multiple sets of magnet sheets, further improving assembly efficiency.

[0007] Optionally, the rotating mechanism includes a positioning base, a rotating drive component disposed at the bottom of the positioning base, a rotating shaft disposed on the output shaft of the rotating drive component, and a positioning mold sleeve limited and sleeved on the rotating shaft. An origin sensing plate is also sleeved on the rotating shaft, and a photoelectric switch for detecting the origin sensing plate is disposed on the positioning base.

[0008] By adopting the above technical solution, the rotation drive component of the rotating mechanism drives the rotating shaft to rotate, thereby driving the positioning and placement seat to rotate. The positioning mold sleeve is limited and fitted on the rotating shaft so that the rotor core can rotate with the rotating shaft. The original point sensing plate and photoelectric switch work together to achieve precise positioning of the rotation position, improving the accuracy and efficiency of the magnetic steel sheet assembly.

[0009] Optionally, the positioning mold sleeve has a limiting insertion hole for inserting the rotor, and the rotor and the positioning mold sleeve are circumferentially fixed through the limiting insertion hole. The outer wall of the rotating shaft is provided with a first driving surface, the inner wall of the positioning mold sleeve is provided with a second driving surface that abuts against the first driving surface, and the inner wall of the positioning placement seat is provided with bearing components that rotate with the rotating shaft at intervals.

[0010] By adopting the above technical solution, the rotor and the positioning mold sleeve can be circumferentially fixed by using the limiting insertion hole. The abutment between the first driving surface and the second driving surface can drive the rotating shaft to rotate the positioning mold sleeve. The rotational cooperation between the bearing component and the rotating shaft can ensure the stable rotation of the rotating shaft. Overall, the positioning accuracy and rotational stability of the equipment are improved, thereby increasing the assembly efficiency of the magnetic steel sheet.

[0011] Optionally, the transfer mechanism includes a translation component and a lifting component. The translation component includes a translation plate for mounting the positioning and placement seat, a horizontally arranged translation screw, and a translation drive component for driving the translation screw to rotate. The bottom of the translation plate is provided with a translation drive block that is threadedly engaged with the translation screw. The lifting component includes a lifting drive component, a cylinder mounting plate for mounting the lifting drive component, and a connector disposed on the output shaft of the lifting drive component. The other end of the connector is fixed to the bottom of the positioning and placement seat.

[0012] By adopting the above technical solution, the translation drive component drives the translation screw to rotate, which in turn moves the translation drive block that is threadedly engaged with the translation screw, thereby causing the positioning placement seat mounted on the translation plate to move horizontally; the lifting drive component drives the positioning placement seat to lift and lower through the connecting component, realizing the horizontal movement and lifting of the positioning placement seat, improving the flexibility of the positioning placement seat position adjustment during the magnetic steel sheet assembly process, and improving the working efficiency of the automatic assembly and dispensing equipment for magnetic steel sheets.

[0013] Optionally, the dispensing mechanism includes two sets of dispensing mounting seats symmetrically arranged along the axis of the positioning and placement seat, a dispensing valve slidably disposed on the dispensing mounting seat, and a dispensing drive component for driving the dispensing valve to slide. A pressure holding valve is provided at the bottom of the assembly bracket.

[0014] By adopting the above technical solution, the two sets of symmetrical dispensing mounting seats of the dispensing mechanism can ensure the balance and stability of dispensing. The dispensing valve can slide on the dispensing mounting seat and can flexibly adjust the dispensing position. The dispensing drive component drives the dispensing valve to slide to realize the automation of dispensing. The pressure holding valve can ensure the pressure stability of the dispensing process, thereby improving the assembly efficiency and connection strength of the magnet sheet and the rotor core.

[0015] Optionally, the pressing mechanism includes a pressing fixing plate, a guide component disposed on the pressing fixing plate, a pressing limiting strip with one end corresponding to the guide component and used for storing the magnetic steel sheet, and a pressing component disposed on the assembly bracket and used for pressing the magnetic steel sheet.

[0016] By adopting the above technical solution, the pressing and fixing plate can be equipped with a guide component, which provides guidance for the pressing of the magnetic steel sheet. The pressing and limiting strip can store the magnetic steel sheet, and the pressing and fixing component can press the magnetic steel sheet, realizing the simultaneous pressing of multiple sets of magnetic steel sheets and improving the assembly efficiency of the magnetic steel sheet and the rotor core.

[0017] Optionally, the guide assembly includes an upper guide block and a lower guide block respectively fixed to the upper and lower sides of the press-fit fixing plate. The outer side wall of the upper guide block is provided with a feeding groove that communicates with the press-fit limiting strip. The upper guide block has an upper guide hole that penetrates through both end faces. The lower guide block has a guide insertion hole that is inserted into the rotor shaft, and a lower guide hole corresponding to the upper guide hole is provided outside the guide insertion hole.

[0018] By adopting the above technical solution, the feeding trough is connected to the pressing limit strip, which facilitates the entry of the magnetic steel sheet into the upper guide block. The upper guide hole penetrates through both ends of the upper guide block, and the lower guide hole corresponds one-to-one with the upper guide hole. The guide insertion hole of the lower guide block is inserted into the rotor shaft, which can provide accurate guidance for the pressing of the magnetic steel sheet, so that the magnetic steel sheet can be smoothly inserted into the magnetic steel slot of the rotor core. In conjunction with other mechanisms of the automatic magnetic steel sheet assembly dispensing equipment, the assembly efficiency of the magnetic steel sheet and the rotor core is improved.

[0019] Optionally, the pressing assembly includes a pressing plate, a pressing linear module disposed on the pressing plate, a push rod seat disposed on the driving block of the pressing linear module, and a pressing push rod disposed on the push rod seat. The pressing push rod corresponds one-to-one with the upper guide block, and the pressing push rod is partially inserted into the upper guide hole.

[0020] By adopting the above technical solution, the assembly bracket, rotating mechanism, transfer mechanism, dispensing mechanism and pressing mechanism work together to realize automatic assembly and dispensing of magnetic steel sheets, thereby improving the assembly efficiency of magnetic steel sheets and rotor core; the pressing linear module of the pressing assembly drives the pressing push rod to move through the push rod seat. The pressing push rod corresponds to the upper guide block and is partially inserted into the upper guide hole, which can accurately press the magnetic steel sheet to the designated position, further improving the pressing efficiency and accuracy of the magnetic steel sheet.

[0021] In summary, this application includes at least one of the following beneficial technical effects: The pressing mechanism can press multiple sets of magnets simultaneously, solving the problem of low assembly efficiency caused by manually inserting magnets one by one, and improving the assembly efficiency of magnets and rotor core. It can meet the needs of large-scale production, solve the problem that existing assembly methods cannot meet the production needs in large-scale production, and improve the production speed and output of motors; By coordinating the rotation mechanism, transfer mechanism, dispensing mechanism, and pressing mechanism, the assembly and dispensing of magnetic steel sheets are automated, reducing manual operation, avoiding the influence of skill level and working condition on manual operation, and improving the stability of assembly quality.

[0037] Reference Figure 2 and Figure 3 The rotating mechanism 2 includes a rotating drive 22 fixed to the bottom of the positioning base 21, a rotating shaft 23 connected to the output shaft of the rotating drive 22, and a positioning mold sleeve 24 sleeved on the rotating shaft 23. The positioning base 21 is a column extending through both the top and bottom. The rotating drive 22 is a stepper motor as in the prior art, with its output shaft arranged vertically upwards. The motor end cover of the rotating drive 22 is fixedly connected to the bottom of the positioning base 21.

[0038] The output shaft of the rotating shaft 23 and the rotating drive component 22 are coaxially fixed. The positioning base 21 has a positioning rotation groove 211 for the rotating shaft 23 to be inserted. A thrust bearing is installed in the positioning rotation groove 211 of the positioning base 21, and a thrust clamping ring 232 is pressed against the thrust bearing on the outside of the rotating shaft 23.

The sensing notch 251 corresponds to a set of limiting arc surfaces 2411 of the positioning mold sleeve 24, so that when the rotor core 6 is inserted into the positioning mold sleeve 24, the magnet slot of the rotor corresponds to the sensing notch 251, ensuring the accuracy of dispensing.

[0042] A photoelectric switch 26 corresponding to the origin sensing plate 25 is provided on the positioning base 21. The photoelectric switch 26 is used to detect whether the sensing notch 251 is in the initial state. In the initial state, the sensing notch 251 and the photoelectric switch 26 correspond. When the rotor core 6 is inserted into the positioning mold sleeve 24 and the sensing notch 251 and the photoelectric switch 26 are interleaved, the control rotation drive 22 rotates the rotating shaft 23 to the initial state.

A pressure holding valve 44 is also installed at the bottom of the mounting bracket 1 to ensure the internal pressure of the dispensing valve 42.

[0049] After the rotating shaft 23 rotates to the initial state, the dispensing drive 43 is activated to move the dispensing valve 42 toward the positioning seat 21, so that the output end of the dispensing valve 42 corresponds to the magnet slot. The dispensing valve 42 is activated to squeeze the glue out of the valve body. At the same time, the rotating mechanism 2 is moved to make the glue evenly applied to the magnet slot. After dispensing a set of magnet slots, the rotor core 6 is rotated 90 degrees and the above actions are repeated to dispense glue to the other set of magnet slots of the rotor.

[0057] The implementation principle of the automatic assembly and dispensing equipment for magnetic steel sheets in this application embodiment is as follows: The rotor core 6 is positioned and inserted into the positioning mold sleeve 24. The rotating shaft 23 is rotated to the initial position by the rotating mechanism 2. Then, the dispensing drive 43 is started, and the dispensing valve 42 is moved so that the output port of the dispensing valve 42 is close to one end of the magnetic steel slot. The dispensing valve 42 is started to dispense glue. At the same time, the translation plate 311 is moved horizontally by the transfer mechanism 3 so that the glue is evenly applied to the opening of the magnetic steel slot. After completing one set of glue application, the rotor core 6 is rotated 90 degrees and then glue is applied to another set of magnetic steel slots. Afterward, the positioning placement seat 21 is moved to the bottom of the pressing and fixing plate 51 by the translation component 31. The positioning placement seat 21 is lifted by the lifting component 32 so that the rotor core 6 and the lower guide block 522 are inserted and engaged. The pressing component 53 is started to insert four sets of magnetic steel sheets into the rotor core 6 at the same time. The positioning placement seat 21 is retracted and the rotor core 6 with the completed magnetic steel sheet assembly is removed.
