Description
Technical Field
[0001] The invention belongs to the technical field of motors and relates to a stator assembly tool for a linear motor. Background Art
[0002] A linear motor is a transmission device that converts electrical energy into linear motion without any intermediate conversion mechanism. A linear motor generally consists of a rotor and a stator, with multiple magnets mounted on the stator to form a magnetic circuit.
[0003] The stator of a linear motor mainly installs magnets on a magnetic plate with magnetic conductivity. There is a certain distance between each magnet on the magnetic plate, and at the same time ensures that the magnets will not move on the magnetic plate, and the magnets will not fall off when the linear motor moves.
[0004] Currently, most linear motor stators are manufactured by gluing magnets to the surface of a magnetic plate, creating a magnetic field loop between the magnets and the stator. This gluing method is typically done manually, which is time-consuming and labor-intensive, and prone to errors. Summary of the Invention

[0023] Compared with the prior art, the present invention has the following beneficial effects:
[0024] (1) The present invention provides a linear motor stator assembly tool, which realizes the automated assembly of the linear motor stator, thereby improving work efficiency and assembly accuracy;
[0025] (2) Through a reciprocating movement of the movable plate, relying on the convex part on the bearing bar, on the one hand, the magnetic steel sheet can be loaded into the corresponding groove on the magnetic conductive plate, and on the other hand, the plastic sheet adjacent to the magnetic steel sheet can be pulled out of the storage channel and taken out of the storage box through the sliding channel to prepare for the installation of the next magnetic steel sheet. No manual operation is required throughout the process, realizing true automatic assembly;
[0026] (3) Since the magnetic attraction between the magnetic steel sheet on the first bearing part and the magnetic conductive plate is a morphological "mutation" process, a chamfer is provided on the first bearing part to allow the magnetic steel sheet to tilt during the "mutation" process and reliably attract the magnetic conductive plate, thereby achieving reliable installation of the magnetic steel sheet;

[0049] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.
[0050] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0051] like Figure 1 The figure shows the structure of a stator 80 in a linear motor. The stator 80 includes a magnetic plate 81 with a plurality of grooves along its length. Multiple magnetic steel sheets 30 are embedded in the corresponding grooves and secured to the plate 81 with a colloid. Adjacent magnetic steel sheets 30 with the same orientation have opposite magnetic poles. That is, if the north pole of one magnetic steel sheet 30 faces upward, the south pole of the adjacent magnetic steel sheet 30 faces upward.
[0052] like Figures 2 to 9 As shown, the present invention provides a linear motor stator assembly tool, comprising:
[0053] The assembly plate 10 includes an upper surface 11, a lower surface 12, and a through groove 13, and the through groove 13 passes through the upper surface 11 and the lower surface 12;
[0054] The storage box 20 is mounted on the upper surface 11 and includes:
[0055] Multiple vertically arranged storage channels 21, wherein a portion of the storage channels 21 stores magnetic steel sheets 30 stacked with the N pole facing upward, and another portion of the storage channels 21 stores magnetic steel sheets 30 stacked with the S pole facing upward, wherein the two ends of the storage channels 21 are the feed end and the discharge end respectively, and adjacent magnetic steel sheets 30 are separated by a plastic sheet 40;
[0056] A plurality of sliding channels 22 and a plurality of assembly cavities 23 are respectively located on both sides of the discharge end of the corresponding storage channel 21, and the sliding channels 22 and the assembly cavities 23 are both connected to the storage channel 21, wherein the through groove 13 is located below the assembly cavity 23;
[0057] The discharge frame 50 is connected to the lower surface 12 and includes:
[0058] A discharge channel 51 is vertically arranged and communicates with the through slot 13;
[0059] The movable plate 60 slides on the upper surface 11, and a plurality of supporting bars 61 are provided on the movable plate 60, wherein each supporting bar 61 is inserted into the corresponding sliding channel 22, and a protrusion 62 is provided on each supporting bar 61. The width difference between the supporting bar 61 and the sliding channel 22 is greater than the thickness of the single magnetic steel sheet 30, and less than the sum of the thickness of the single magnetic steel sheet 30 and the single plastic sheet 40; the thickness of the plastic sheet 40 is greater than the thickness of the protrusion 62, and less than the width difference between the supporting bar 61 and the sliding channel 22.
[0060] The present invention provides a working principle of a stator assembly tool for a linear motor. In the initial state, the bottom magnetic steel sheet 30 of the stacked magnetic steel sheets 30 in the storage channel 21 abuts against the corresponding supporting bar 61. First, the magnetic conductive plate 81 coated with colloid in the groove is inserted into the discharge channel 51, and the magnetic conductive plate 81 is pushed into the preset position in the through groove 13 by an external mechanism (such as a cylinder), and the groove on the magnetic conductive plate 81 faces the assembly cavity 23. Then, the movable plate 60 is pushed so that the protrusion 62 on the supporting bar 61 contacts the side wall of the bottom magnetic steel sheet 30. As the supporting bar 61 moves, the bottom magnetic steel sheet 30 is separated from the adjacent plastic sheet 40, and the bottom magnetic steel sheet 30 is pushed into the corresponding assembly cavity 23. Through the magnetic attraction between the magnetic steel sheet 30 and the magnetic conductive plate 81, the magnetic steel sheet 30 located on the supporting bar The end of the magnetic steel sheet 30 on 61 close to the assembly cavity 23 is first attracted to the magnetic conductive plate 81. At this time, the magnetic steel sheet 30 on the supporting bar 61 is arranged at an angle. In addition, the protrusion 62 on the supporting bar 61 has passed the storage channel 21, so that the plastic sheet 40 adjacent to the currently assembled magnetic steel sheet 30 falls onto the supporting bar 61; then the movable plate 60 is pulled out. On the one hand, the contact area between the magnetic steel sheet 30 on the bottom layer gradually reduces the contact area with the corresponding supporting bar 61. When the magnetic steel sheet 30 on the bottom layer completely loses the support of the supporting bar 61, the entire magnetic steel sheet 30 is installed in the corresponding groove and is arranged horizontally. On the other hand, as the movable plate 60 is pulled out, the plastic sheet 40 is brought out of the sliding channel 22, completing the assembly of the magnetic steel sheet 30. Finally, the assembled stator 80 is moved out of the discharge channel 51 through an external mechanism.
[0061] The present invention provides a linear motor stator assembly tool, which realizes the automated assembly of the linear motor stator 80 and improves work efficiency and assembly accuracy.
[0062] It is worth mentioning that the protrusion 62 and the corresponding supporting bar 61 are integrally arranged, and the two sides of the protrusion 62 along the moving direction of the movable plate 60 are respectively a first contact surface 621 and a second contact surface 622, wherein the first contact surface 621 faces one side of the assembly cavity 23, and the second contact surface 622 faces away from the side of the assembly cavity 23. The first contact surface 621 contacts the magnetic steel sheet 30 at the discharge end of the corresponding storage channel 21 and pushes it away from the storage channel 21, and the second contact surface 622 contacts the plastic sheet 40 at the discharge end of the corresponding storage channel 21 and pulls it away from the storage channel 21.
[0063] It can be seen from this that through one reciprocating movement of the movable plate 60, relying on the protrusion 62 on the supporting bar 61, on the one hand, the magnetic steel sheet 30 can be loaded into the corresponding groove on the magnetic conductive plate 81, and on the other hand, the plastic sheet 40 adjacent to the magnetic steel sheet 30 can be pulled out of the storage channel 21 and brought out of the storage box 20 through the sliding channel 22, preparing for the installation of the next magnetic steel sheet 30. No manual operation is required throughout the process, realizing true automated assembly.
[0064] It is further pointed out that a first bearing portion 611 is formed between the first contact surface 621 of the protrusion 62 on the bearing bar 61 and the end surface of the bearing bar 61 facing the assembly cavity 23, and a second bearing portion 612 is formed between the second contact surface 622 of the protrusion 62 on the bearing bar 61 and the end surface of the bearing bar 61 facing away from the assembly cavity 23. The first bearing portion 611 is used to carry the magnetic steel sheet 30, and the second bearing portion 612 is used to carry the plastic sheet 40. Specifically, when the movable plate 60 is in the process of being withdrawn from the storage box 20 and the plastic sheet 40 is completely located outside the storage box 20, a portion of the structure of the first bearing portion 611 is still located below the storage channel 21. This structural arrangement ensures that when the plastic sheet 40 is withdrawn, the first bearing portion 611 can still reliably receive the next magnetic steel sheet 30 to be assembled, thereby ensuring the reliability of the assembly of the magnetic steel sheet 30.
[0065] Further preferably, a chamfer 613 is provided on one end of the first bearing portion 611 facing the assembly cavity 23 .
[0066] It is worth mentioning that when the first bearing portion 611 carries the magnetic steel sheet 30, a portion of the magnetic steel sheet 30 is completely in contact with the first bearing portion 611, and the other portion of the magnetic steel sheet 30 is just above the chamfer 613 and is in a "suspended" state. As the bearing bar 61 gradually approaches the assembly cavity 23, when the magnetic steel sheet 30 on the first bearing portion 611 is magnetically attracted to the magnetic plate 81, the end in the "suspended" setting will fall under the action of the "magnetic force" and fit with the surface of the chamfer 613, and the end originally in contact with the first bearing portion 611 will be in contact with the surface of the chamfer 613. 11 is completely fitted at one end, which "tilts up" so that the entire magnetic steel sheet 30 is "tilted". Then, as the supporting bar 61 moves further, when the magnetic steel sheet 30 reaches the preset position, the supporting bar 61 moves in the opposite direction. Since there is magnetic force between the magnetic steel sheet 30 and the magnetic plate 81, the magnetic steel sheet 30 will not follow the reverse movement of the supporting bar 61 but follow it synchronously. When the magnetic steel sheet 30 is completely separated from the corresponding first supporting portion 611, the magnetic steel sheet 30 is completely embedded in the groove corresponding to the magnetic plate 81, completing the installation of the magnetic steel sheet 30.
[0067] In this embodiment, since the magnetic attraction between the magnetic steel sheet 30 on the first supporting portion 611 and the magnetic conductive plate 81 is a morphological "mutation" process, a chamfer 613 is provided on the first supporting portion 611 to allow the magnetic steel sheet 30 to tilt during the "mutation" process and reliably attract the magnetic conductive plate 81, thereby achieving reliable installation of the magnetic steel sheet 30.
[0068] Further preferably, a guiding inclined surface 231 is provided on the bottom of the assembly cavity 23 , and the inclined direction of the guiding inclined surface 231 is parallel to the inclined direction of the chamfer 613 .
[0069] In this embodiment, by providing a guiding slope 231, when the "suspended" end of the magnetic steel sheet 30 on the first bearing portion 611 is magnetically attracted to the magnetic conductive plate 81, the tilted magnetic steel sheet 30 is exactly located between the chamfer 613 and the guiding slope 231, and there is a gap between the surface of the tilted magnetic steel sheet 30 and the guiding slope 231, or they are in contact with each other, thereby avoiding interference between the magnetic steel sheet 30 and the bottom of the assembly cavity 23 during the assembly process, thereby further improving the reliability of the installation of the magnetic steel sheet 30.
[0070] It is further pointed out that the opening direction of the assembly cavity 23 is toward the discharge channel 51, and the lengths on both sides of the opening end of the assembly cavity 23 are inconsistent, wherein the length of the end of the assembly cavity 23 connected to the sliding channel 22 is shorter than the length of the end of the assembly cavity 23 away from the sliding channel 22, and the end of the assembly cavity 23 away from the sliding channel 22 extends into the through groove 13.
[0071] In this embodiment, one end of the assembly cavity 23 away from the sliding channel 22 is extended into the through groove 13, and the end surface of this end can be used as a positioning surface to control the distance that the magnetic conductive plate 81 extends into the through groove 13 under the action of an external mechanism, thereby ensuring that the subsequent magnetic steel sheet 30 can be reliably installed in the corresponding groove on the magnetic conductive plate 81.
[0072] Preferably, the multiple storage channels 21 are divided into two groups and are located on both sides of the storage box 20, respectively. The storage channels 21 in one group are the first storage channels 211, and the storage channels 21 in the other group are the second storage channels 212. Any two adjacent first storage channels 211 are separated by a first baffle 213, and any two adjacent second storage channels 212 are separated by a second baffle 214. The positions of the multiple first storage channels 211 and the positions of the multiple second storage channels 212 are staggered in the horizontal plane, and the first storage channels 211 are used to place the magnetic steel sheets 30 with the N pole facing upward and stacked, and the second storage channels 212 are used to place the magnetic steel sheets 30 with the S pole facing upward and stacked.
[0073] It is worth mentioning that the positions of the multiple first storage channels 211 and the positions of the multiple second storage channels 212 are staggered in the horizontal plane, which means that the first baffle 213 between any two adjacent first storage channels 211 and one of the multiple second storage channels 212 are on the same straight line, and the second baffle 214 between any two adjacent second storage channels 212 and one of the multiple first storage channels 211 are on the same straight line.
[0074] It is further pointed out that the two sides of the discharge end of the first storage channel 211 are the first sliding channel 221 and the first assembly cavity 232 respectively, and the two sides of the discharge end of the second storage channel 212 are the second sliding channel 222 and the second assembly cavity 233 respectively, and the first sliding channel 221 and the second sliding channel 222 are located on both sides of the storage box 20 and are staggered, and the first assembly cavity 232 and the second assembly cavity 233 are on the same straight line and are spaced apart.
[0075] In this embodiment, the first material storage channel 211 and the second material storage channel 212 are staggered, the first sliding channel 221 and the second sliding channel 222 are staggered, the first assembly cavity 232 and the second assembly cavity 233 are on the same straight line and are spaced apart. This arrangement can achieve the synchronous installation of the magnetic steel sheet 30 with the N pole facing upward and the magnetic steel sheet 30 with the S pole facing upward, and the magnetic steel sheet 30 with the N pole facing upward and the magnetic steel sheet 30 with the S pole facing upward on the magnetic conductive plate 81 are spaced apart, further improving the assembly efficiency of the stator 80 of the linear motor.
[0076] Preferably, a hot air conduction chamber 24 is provided on the storage box 20 between the first storage channel 211 and the second storage channel 212, and at least one hot air inlet hole 241 is provided on the cavity wall of the hot air conduction cavity 24, and a plurality of hot air outlet holes 242 are provided on the cavity bottom of the hot air conduction cavity 24, and the position of the hot air outlet hole 242 corresponds to the position of the guide slope 231, wherein the hot air outlet hole 242 passes through the cavity bottom of the hot air conduction cavity 24 and extends into the assembly cavity 23.
[0077] In this embodiment, by providing the hot air conduction chamber 24, the curing time of the colloid can be further shortened, and the connection between the magnetic steel sheet 30 and the magnetic conductive plate 81 can be accelerated, thereby further improving the assembly efficiency of the stator 80 of the linear motor.
[0078] It is further pointed out that a step 25 is provided at the cavity opening of the hot air conduction cavity 24 , and a sealing plate 26 is placed on the step 25 , and the sealing plate 26 is connected to the step 25 by fasteners, wherein the cavity opening of the hot air conduction cavity 24 is sealed by the sealing plate 26 .
[0079] It is worth mentioning that due to the processing technology of the hot air conduction cavity 24, the cavity opening of the hot air conduction cavity 24 will be an open structure, which will cause the hot air in the hot air conduction cavity 24 to "escape" from the cavity opening, reducing the utilization rate of the hot air. The cavity opening of the hot air conduction cavity 24 is sealed by the sealing plate 26, so that the interior of the hot air conduction cavity 24 becomes a relatively "closed" space, thereby improving the utilization rate of the hot air and shortening the curing time of the colloid.
[0080] Preferably, a driving motor 70 is further provided on the assembly table 10 , and the output end of the driving motor 70 is connected to the movable plate 60 , wherein a slide groove 14 is provided on the upper surface 11 of the assembly table 10 , and the slide groove 14 is slidably matched with the movable plate 60 .

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.
