Description

A magnetic tile assembly device for a stator assembly

Technical Field

The invention relates to the technical field of special equipment for motor assembly, and in particular to magnetic shoe assembly equipment for a stator assembly.

Background technique

The motor stator is an important part of the motor, which is mainly used to generate a rotating magnetic field. The existing motor stator includes a shell and magnetic tiles evenly distributed in the shell. The magnetic tiles are mainly used in permanent magnet motors. Unlike electromagnetic motors that generate magnetic potential sources through excitation coils, permanent magnet motors use permanent magnetic materials to generate constant magnetic potential sources. Permanent magnetic tiles instead of electric excitation have many advantages, which can make the motor simple in structure, easy to maintain, light in weight, small in size, reliable in use, less copper, low copper consumption, and low energy consumption.

On the one hand, the magnetic tiles are adsorbed on the inner wall of the shell by magnetic attraction, and on the other hand, they are bonded to the inner wall of the shell by adhesive. In order to keep the adjacent magnetic tiles at equal angles, it is necessary to wait for a period of time (generally 5-10 minutes) after the magnetic tiles are bonded to the inner wall of the shell to ensure that the adjacent magnetic tiles will not be attracted. For example, a Chinese patent (application publication number CN218217048U) discloses a stator magnetic bonding tool for a starting motor, which includes a positioning seat, a plurality of pins corresponding to the magnetic tiles are arranged on the top surface of the positioning seat, a through hole is provided on the positioning seat, and a limiting portion movably inserted in the through hole is provided, and a plurality of installation spaces for installing the magnetic tiles are provided between the outer wall of the limiting portion and each pin, and a gluing channel connecting the installation space and being used for gluing the magnetic tiles from the bottom of the casing is provided upwardly through the limiting portion and the bottom of the base. Since the magnetic tiles need to wait for the adhesive to dry naturally after assembly, the assembly efficiency of the existing magnetic tile assembly equipment is low.

Summary of the invention

The purpose of the present invention is to provide a magnetic tile assembly device for a stator assembly, which ensures that adjacent magnetic tiles are adsorbed on the inner wall of the outer shell at equal intervals by assembling magnetic isolation between adjacent magnetic tiles, thereby solving the problem of having to wait for a long time for the adhesive to dry naturally during assembly, thereby greatly improving the assembly efficiency of the magnetic tiles.

The magnetic separator pushing mechanism includes a mounting seat, a magnetic separator and a third driving mechanism. The output end of the third driving mechanism is provided with a pushing claw. Under the action of the third driving mechanism, the pushing claw can push the magnetic separator installed in the mounting seat into the retreat space so that the magnetic separator separates adjacent magnetic tiles.

Furthermore, the first driving mechanism includes a movable shaft and a cylinder. The movable shaft is arranged in the sleeve rod and can move axially along the sleeve rod under the action of the cylinder. The sleeve rod is provided with a plurality of groups of accommodating holes penetrating the outer wall of the sleeve rod along its radial direction. The partition is accommodated in the accommodating hole. The axial reciprocating movement of the movable shaft is used to drive the partition to switch between a first position extending out of the accommodating hole and a second position retracted into the accommodating hole.

Furthermore, a guide surface with a gradually increasing outer diameter is provided on the outer periphery of the movable shaft, an elastic member is provided in the accommodating hole to drive the partition to bias toward the movable shaft, the inner end of the partition abuts against the outer wall of the movable shaft under the action of the elastic member, and a limiting member is provided on the sleeve rod to prevent the partition from falling out of the accommodating cavity.

Furthermore, the movable shaft is axially provided with multiple sections of consistent guide surfaces, and the sleeve rod is provided with multiple rows of accommodating holes matching the guide surfaces. Each accommodating hole accommodates a partition and an elastic member that drives the partition to bias toward the movable shaft, and the partition is against the guide surface on the movable shaft.

Furthermore, the push claw is fixedly connected to the movable shaft, and the cylinder of the first driving mechanism also serves as the third driving mechanism. When the cylinder outputs, it drives the push claw and the movable shaft to move synchronously along the axial direction of the sleeve rod.

Furthermore, the mounting seat is fixedly installed on the outer periphery of the sleeve rod, and multiple groups of guide grooves are provided around the mounting seat. A limiting ring is provided on the outer periphery of the mounting seat corresponding to the guide groove. The magnetic partition is installed in the guide groove and can move along the guide groove to the avoidance space of the adjacent magnetic tile under the action of the push claw.

The magnetic tiles are pre-installed on the outer periphery of the sleeve rod through magnetic attraction with the iron rings. The magnetic attraction between the magnetic tiles and the outer shell is greater than the magnetic attraction between the magnetic tiles and the iron rings, so that when the outer shell moves to the outer periphery of the magnetic tiles, the magnetic tiles can be adsorbed on the inner wall of the outer shell.

Furthermore, a guide ring is extended from the other side of the sleeve rod relative to the motor, a guide portion matching the inner diameter of the guide ring is provided on the outer side of the movable shaft, a socket for inserting the magnetic tile and the sleeve rod is provided at the insertion end of the shell, and a through hole for the guide ring to pass through is provided at the other end of the shell.

The magnetic tile assembly equipment of the present invention first separates the magnetic tiles pre-installed on the sleeve rod at equal intervals through multiple groups of partitions. When the outer shell is transferred to the outer periphery of the sleeve rod, the magnetic tiles are adsorbed on the inner wall of the outer shell because the magnetic attraction between the magnetic tiles and the outer shell is greater than the magnetic attraction between the magnetic tiles and the iron ring. At the same time, due to the constraints of the partitions, the adjacent magnetic tiles are evenly separated. At this time, the first driving mechanism drives the partition to move to form a retreat space between adjacent magnetic tiles. At the same time, the third driving mechanism pushes the magnetic partition into the retreat space of adjacent magnetic tiles to ensure that the adjacent magnetic tiles are adsorbed on the inner wall of the outer shell at equal intervals, thereby solving the problem of having to wait for the adhesive to dry naturally for a long time during assembly, thereby greatly improving the assembly efficiency of the magnetic tiles.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings.

As shown in Figures 1-11, a magnetic tile assembly device for a stator assembly includes a magnetic tile pre-installation mechanism 1, a magnetic isolation pushing mechanism 2 and a shell transfer mechanism 3, which constitute the basic structure of the present invention. The magnetic tile 14 assembly device also includes a base 4, a glue dispensing mechanism 5 and a magnetic tile distribution mechanism 6. The magnetic tile pre-installation mechanism 1, the magnetic isolation pushing mechanism 2 and the shell transfer mechanism 3 are arranged on the base 4. The glue dispensing mechanism 5 is used to dispense glue on the outer wall of the magnetic tile 14 pre-installed on the periphery of the sleeve rod 12. The glue dispensing mechanism 5 includes a glue dispenser, a first transverse movement mechanism 41 that drives the glue dispenser to move transversely, and a first vertical movement mechanism 42 that drives the glue dispenser to move vertically. The base 4 is provided with a second transverse movement mechanism 43 that drives the magnetic tile pre-installation mechanism 1 to move between the glue dispensing station and the magnetic tile 14 distribution station. The magnetic tile distribution mechanism 6 is a prior art and is not described in detail in the present invention.

The magnetic tile pre-installation mechanism 1 includes a support base 11, a sleeve rod 12 rotatably set on the support base 11, a motor 13 driving the sleeve rod 12 to rotate, multiple groups of magnetic tiles 14 pre-installed on the outer periphery of the sleeve rod 12, multiple groups of partitions 15 for separating adjacent magnetic tiles 14, and a first driving mechanism 16 that drives the partitions 15 to move to form a retreat space between adjacent magnetic tiles 14, wherein the motor 13 drives the sleeve rod 12 to rotate, and when the magnetic tile 14 rotates with the sleeve rod 12, the glue dispensing mechanism 5 is used to perform uniform glue dispensing on the outer curved surface of the magnetic tile 14.

The first driving mechanism 16 includes a movable shaft 161 and a cylinder 162. The movable shaft 161 is arranged in the sleeve rod 12 and can move axially along the sleeve rod 12 under the action of the cylinder 162. Specifically, a mounting plate is connected to the support seat 11. The cylinder 162 is provided with two groups and is symmetrically installed at both ends of the mounting plate. The output ends of the two cylinders 162 are connected with a connecting plate. The first end of the movable shaft 161 is connected to the connecting plate so that the cylinder 162 can drive the movable shaft 161 to move axially along the sleeve rod 12 when outputting. The sleeve rod 12 is provided with a plurality of groups of accommodating holes 121 penetrating the outer wall of the sleeve rod 12 along its radial direction. The partition 15 is accommodated in the accommodating hole 121. The axial reciprocating movement of the movable shaft 161 drives the partition 15 to switch between a first position extending out of the accommodating hole 121 and a second position retracted into the accommodating hole 121.

The outer periphery of the movable shaft 161 is provided with a guide surface 1611 with an outer diameter gradually expanding, and an elastic member 163 is provided in the accommodating hole 121 to drive the partition 15 to bias toward the movable shaft 161. The inner end of the partition 15 abuts against the outer wall of the movable shaft 161 under the action of the elastic member 163, and the sleeve rod 12 is provided with a limiter to prevent the partition 15 from falling out of the accommodating cavity. In the present invention, in order to facilitate the assembly of the partition 15 and the elastic member 163, the limiter and the sleeve rod 12 adopt a split design. During installation, the partition 15 and the elastic member 163 are first assembled into the accommodating hole 121, and then the limiter is installed at the outer end of the accommodating hole 121. Preferably, the iron ring 122 also serves as a limiter. Specifically, the iron ring 122 is fixedly arranged on the sleeve rod 12 corresponds to the outer periphery of the accommodating hole 121, and a through hole is opened on the iron ring 122 for the partition 15 to partially extend out. The position of the through hole corresponds to the position of the accommodating hole 121, and the iron ring 122 plays a limiting role, thereby greatly shortening the assembly time of spare parts. When the movable shaft 161 moves outward, the outer diameter of the guide surface 1611 gradually narrows, so that the partition 15 retracts into the accommodating hole 121 under the elastic force of the elastic member 163, that is, the partition 15 is in the second position at this time. When the movable shaft 161 moves inward, the outer diameter of the guide surface 1611 gradually increases, so that the partition 15 extends out of the accommodating hole 121 under the action of the guide surface 1611, that is, the partition 15 is in the first position at this time.

The separator 15 includes a ball head and a separator column arranged at the upper end of the ball head. The connection between the ball head and the separator column forms a step surface. The elastic member 163 is disposed between the step surface and the limit member. The ball head abuts against the guide surface 1611.

The movable shaft 161 is axially provided with a plurality of consistent guide surfaces 1611, and the sleeve rod 12 is provided with a plurality of rows of accommodating holes 121 matching the guide surfaces 1611. A separator 15 and an elastic member 163 for biasing the separator 15 toward the movable shaft 161 are accommodated in each accommodating hole 121. The separator 15 abuts against the guide surface 1611 on the movable shaft 161. In the present invention, two rows of accommodating holes 121 are provided on the sleeve rod 12, and two consistent guide surfaces 1611 are circumferentially provided on the movable shaft 161, which is equivalent to providing two rows of separators 15 on the sleeve rod 12, so as to ensure that the separators 15 stably separate the magnetic tiles 14 at both ends thereof, and avoid the problem that one end of the adjacent magnetic tiles 14 is separated by the separators 15 and the other end is attracted.

The shell transfer mechanism 3 includes a shell 31 and a second drive mechanism 32. The shell 31 can be moved to the periphery of the magnetic tile 14 under the drive of the second drive mechanism 32 to attract the magnetic tile 14 to the inner wall of the shell 31. Specifically, the shell transfer mechanism 3 also includes a fixed seat 33 and a clamping mechanism 34. The fixed seat 33 is provided with a groove for accommodating the shell 31. The fixed seat 33 is provided with a supporting portion at one end close to the sleeve rod 12. The clamping mechanism 34 includes a clamping cylinder 341 that moves synchronously with the fixed seat 33 under the action of the second drive mechanism 32. The output end of the clamping cylinder 341 A clamping block 342 is provided, and the clamping block 342 is arranged at the other end of the fixing seat 33 relative to the abutting portion. The outer shell 31 is fixedly clamped in the groove of the fixing seat 33 by the clamping cylinder 341, that is, the clamping cylinder 341 drives the clamping block 342 to move the outer shell 31 toward the abutting portion, so that the outer shell 31 is clamped between the abutting portion and the clamping block 342. At the same time, the second driving mechanism is used to drive the outer shell 31 to move between the assembly position of the outer periphery of the sleeve rod 12 and the outer end position away from the sleeve rod 12. The second driving mechanism 32 can be an actuator such as a cylinder 162 and an electric cylinder.

At least one group of iron rings 122 is provided at the position where the sleeve rod 12 is pre-installed with the magnetic tile 14. In the present invention, two groups of iron rings 122 are provided at intervals on the outer periphery of the sleeve rod 12. The magnetic tile 14 is pre-installed on the outer periphery of the sleeve rod 12 through the magnetic attraction with the iron rings 122. The magnetic attraction between the magnetic tile 14 and the outer shell 31 is greater than the magnetic attraction between the magnetic tile 14 and the iron rings 122, so that when the outer shell 31 moves to the outer periphery of the magnetic tile 14, the magnetic tile 14 can be adsorbed on the inner wall of the outer shell 31.

A guide ring 123 is extended from the other side of the sleeve rod 12 relative to the motor 13, and a guide portion 1612 matching the inner diameter of the guide ring 123 is provided on the outer side of the movable shaft 161. The insertion end of the shell 31 is provided with a socket for inserting the magnetic tile 14 and the sleeve rod 12, and the other end of the shell 31 is provided with a through hole for the guide ring 123 to pass through.

The magnetic partition pushing mechanism 2 includes a mounting seat 21, a magnetic partition 22 and a third driving mechanism, wherein the magnetic partition 22 is a sheet structure after multiple bendings and is elastic. A push claw 23 is provided at the output end of the third driving mechanism. Under the action of the third driving mechanism, the push claw 23 can push the magnetic partition 22 installed in the mounting seat 21 into the retreat space so that the magnetic partition 22 separates the adjacent magnetic tiles 14. Furthermore, the mounting seat 21 is fixedly installed on the outer periphery of the sleeve rod 12, and a plurality of groups of guide grooves 211 are provided around the mounting seat 21. A limiting ring 212 is provided on the outer periphery of the guide groove 211 of the mounting seat 21 corresponding to the guide groove 211. The limiting ring 212 is provided to prevent the magnetic partition 22 from falling out of the guide groove 211 during the movement along the guide groove 211. The magnetic partition 22 is installed in the guide groove 211 and can move along the guide groove 211 to the avoidance space of the adjacent magnetic tile 14 under the action of the push claw 23.

Furthermore, the push claw 23 is fixedly connected to the movable shaft 161, and the cylinder 162 of the first driving mechanism 16 also serves as the third driving mechanism. When the cylinder 162 is output, it drives the push claw 23 and the movable shaft 161 to move synchronously along the axial direction of the sleeve rod 12, that is, the third driving mechanism is the two groups of cylinders 162 in the first driving mechanism 16. The push claw 23 is fixedly connected to the movable shaft 161 and the connecting plate to ensure that the magnetic partition 22 moves synchronously with the movable shaft 161.

The magnetic tile 14 assembly equipment of the present invention first separates the magnetic tiles 14 pre-installed on the sleeve rod 12 at equal intervals through multiple groups of partitions 15. When the outer shell 31 is transferred to the outer periphery of the sleeve rod 12, the magnetic tiles 14 are adsorbed on the inner wall of the outer shell 31 because the magnetic attraction between the magnetic tiles 14 and the outer shell 31 is greater than the magnetic attraction between the magnetic tiles 14 and the iron ring 122. At the same time, due to the constraints of the partitions 15, the adjacent magnetic tiles 14 are evenly separated. At this time, the first driving mechanism 16 drives the partitions 15 to move to form a retreat space between the adjacent magnetic tiles 14. At the same time, the third driving mechanism pushes the magnetic partitions 22 into the retreat space of the adjacent magnetic tiles 14 to ensure that the adjacent magnetic tiles 14 are adsorbed on the inner wall of the outer shell 31 at equal intervals, thereby solving the problem of having to wait for the adhesive to dry naturally for a long time during assembly, thereby greatly improving the assembly efficiency of the magnetic tiles 14.

The operating principle of the present invention is as follows:

1. After the magnetic tile 14 is glued, the second driving mechanism 32 moves the housing 31 to the assembly position. When the inner cavity of the housing 31 overlaps with the magnetic tile 14, the magnetic tile 14 is attracted by the housing 31 and separated from the sleeve rod 12. The outer arc surface of the magnetic tile 14 is bonded to the inner wall of the outer wall. Since the adjacent magnetic tiles 14 are constrained by the separator 15, the magnetic tiles 14 are arranged at equal intervals on the inner wall of the housing 31.

2. The cylinder 162 pushes the push claw 23, and the movable shaft 161 moves outward synchronously. During the outward movement of the movable shaft 161, the outer diameter of the guide surface 1611 gradually narrows, so that the separator 15 is retracted into the accommodating hole 121 under the elastic force of the elastic member 163. That is, the separator 15 is in the second position at this time, that is, an avoidance space is formed between adjacent magnetic tiles 14, and at the same time, the magnetic separator 22 is pushed between adjacent magnetic tiles 14 under the action of the push claw 23;

3. After the magnetic partition 22 is pushed into place, the second driving mechanism 32 moves the press-fitted stator assembly of the motor 13 (housing 31, magnetic tile 14 and magnetic partition 22) to the outer end position and leaves the press-fitting area. The return stroke of the cylinder 162 drives the push claw 23 and the movable pin to retreat. When the movable shaft 161 moves inward, the outer diameter of the guide surface 1611 gradually increases, so that the partition 15 extends out of the accommodating hole 121 under the action of the guide surface 1611, that is, the partition 15 is in the first position at this time.

The above description is only a preferred embodiment of the present invention, so all equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
