[0002] An electric motor typically consists of a stator and a rotor, with the stator or rotor usually using a core made of laminated pure iron or electromagnetic steel sheets.

[0024] In one possible implementation, the glue application assembly further includes a glue adjustment assembly, which is mounted on the frame and used to adjust the glue thickness on the glue application roller.
[0025] In one possible implementation, the glue adjusting assembly includes: distance adjusting members respectively disposed on both sides of the glue-applying roller along a first direction.
[0026] The glue baffle is set on the distance adjustment component and forms a glue adhesion space between itself and the outer wall of the glue-applying roller.
[0027] The adhesive baffle can be moved in the first direction by adjusting the distance adjustment component to adjust the size of the adhesive adhesion space.
[0028] In one possible implementation, the gluing mechanism further includes a driving component, which comprises:

In the first state, multiple iron chips continuously press against the glue coating roller and are coated with glue.
[0042] The iron core strip is cut, and the iron chips are separated from the iron core strip one by one. In the first state, the iron chips without glue form the bottom iron core, and in the second state, the iron chips with glue are stacked and bonded together.
[0043] Beneficial Effects: Compared with existing technologies, this application provides a gluing mechanism, motor core manufacturing equipment, and manufacturing method. The method involves passing a core strip through a frame, allowing the iron chips on the core strip to pass through the frame sequentially for gluing. During the gluing process, the glue is first stirred and transferred evenly by a glue-spreading component. Then, a glue-coating roller and a pressing component work together to apply glue to a predetermined number of subsequent iron chips without applying glue. The core strip is then cut, causing the iron chips to detach sequentially. The un-glued iron chips form the bottom layer of the core, while the subsequent glued iron chips are stacked and bonded together to form the motor core. This method achieves automatic gluing of the bottom layer of iron chips without applying glue, while the upper layers are glued sequentially. It allows the cut iron chips to be directly bonded to form a motor core, resulting in high automated production efficiency, consistent product quality, and cost savings. Attached Figure Description

[0049] This application provides a gluing mechanism, a motor core manufacturing equipment, and a manufacturing method. To make the objectives, technical solutions, and effects of this application clearer and more explicit, the following detailed description is provided with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit the scope of this application.
[0050] The existing process of manually applying adhesive and bonding iron chips is not only slow and leads to high production costs, but also results in uncontrollable quality of the motor iron cores due to the limitations of manual experience, making it difficult to guarantee the quality of the motor iron cores. Furthermore, the existing stamping mechanism produces the iron chips individually into finished products, which are then glued and bonded together using additional equipment, increasing the number of production steps, including transfer and reordering processes, and significantly reducing production efficiency. Therefore, this application provides the following embodiments to solve the above problems.
[0051] Example 1
[0052] like Figure 1 , Figure 2As shown, this embodiment provides a gluing mechanism. It is used to apply glue to iron chips 11 on an iron core strip 10. The iron core strip 10 moves along a first direction, sequentially passing through a stamping mechanism (not shown in the figure), this gluing mechanism, and a subsequent shearing mechanism (not shown in the figure). During the movement of the iron core strip 10, it is first stamped by the stamping mechanism, thereby forming iron chips 11 on the iron core strip 10. The iron chips 11 remain connected to the iron core strip 10 and enter the gluing mechanism for gluing as the iron core strip 10 moves. The iron chips 11 on the iron core strip 10 are arranged along the first direction. After the iron core strip 10 moves into the gluing mechanism, the gluing mechanism sequentially applies glue to specific (at predetermined intervals) iron chips 11. The gluing mechanism in this embodiment mainly includes: a frame 100, a glue-spreading assembly 200, a glue-coating roller 300, and a pressing assembly 400. The frame 100 can be vertically installed. The vertical direction of the frame 100 when vertically installed is defined as the up-down direction in this structural description. The left-right direction of the frame 100 is defined as the first direction in this structural description. The direction perpendicular to the up-down and left-right directions is defined as the front-back direction. A material passage groove 131 is provided through the left-right sides of the frame 100. The material passage groove 131 is used to pass through the iron core strip 10, allowing the iron core strip 10 to pass through the frame 100 and move in the left-right direction. A glue-spreading assembly 200 is installed inside the frame 100 and is used to agitate and apply glue. A glue-coating roller 300 is rotatably installed inside the frame 100 and located above the glue-spreading assembly 200 (it can be directly above or slightly off-center). The rotation of the glue-coating roller 300 applies the glue from the glue-spreading assembly 200 to the surface of the glue-coating roller 300, thus achieving the function of receiving the glue from the glue-spreading assembly 200. A tablet pressing assembly 400 is mounted on the frame 100 and spaced apart from the coating roller 300. The tablet pressing assembly 400 is positioned above the coating roller 300. An iron core belt 10 passes through the gap between the tablet pressing assembly 400 and the coating roller 300 and moves stepwise from left to right, causing the iron chips 11 to sequentially pass above the coating roller 300. Driven by the tablet pressing assembly 400, the iron core belt 10 has a first state of being close to the coating roller 300 and a second state of being away from the coating roller 300. In the first state, a predetermined number of iron chips 11 continuously pass through the coating roller 300 and are coated with adhesive. In the second state, an iron chip 11 is spaced a predetermined distance from the coating roller 300 and is not coated with adhesive.
[0053] The effect of the gluing mechanism in the above embodiment is as follows: by passing the iron core strip 10 through the frame 100, the iron chips 11 on the iron core strip 10 pass through the frame 100 in sequence and are coated with glue. During the gluing process, the glue is first stirred evenly and transferred by the glue-spreading component. The glue-spreading roller 300 cooperates with the pressing component 400 to apply glue to one iron chip 11 without applying glue, and to apply glue to a predetermined number of subsequent iron chips 11. Subsequently, the iron core strip 10 is cut so that the iron chips 11 are separated from the iron core strip 10 in sequence. The iron chips 11 without glue form the bottom iron core, and the multiple iron chips 11 with glue are stacked and bonded in sequence to form the motor iron core. For example, when the first iron chip 11 passes over the coating roller 300, the pressing assembly 400 is lifted without pressing down on the iron core belt 10. The iron core belt 10 returns to the conveying position. When it is in the conveying position, there is a certain distance between the iron core belt 10 and the surface of the coating roller 300, so that the glue on the coating roller 300 cannot be applied to the first iron chip 11, and the first iron chip 11 is not covered with glue. As the moving iron core belt 10 continues to move to the right, bringing the second iron chip 11 to the adhesive application position, the pressing assembly 400 presses down on the iron core belt 10, causing it to move to the coating position. At this position, the iron core belt 10 abuts against the surface of the adhesive roller 300, allowing the adhesive on the roller to be applied to the second iron chip 11. The lower surface of the second iron chip 11 becomes coated with adhesive. As the iron core belt 10 continues to move, the adhesive roller 300 rotates. When the next iron chip 11 moves to the adhesive application position, the adhesive roller 300, now coated with adhesive, rotates to the lower surface position of the next iron chip 11, applying adhesive to it. The subsequent third to Nth iron chips 11 are all coated with adhesive during the pressing process of the pressing assembly 400. These N iron chips 11 form a group of iron chips 11 for a motor core. During bonding, the bottom of the first iron chip 11 is not coated with glue and is cut off from the core strip 10, located at the bottom layer. Subsequent iron chips 11 are coated with glue at the bottom, cut, and stacked sequentially. This achieves automatic stacking and bonding, thus forming a motor core. The iron chips 11 of the next motor core undergo a second and first state during production, ensuring that the bottom of the first iron chip 11 of the next motor core is not coated with glue, preventing interference between motor cores. This second and first state are executed sequentially and cyclically, enabling continuous production of motor cores. Therefore, the function of automatically not applying glue to the bottom layer of iron chips 11 while sequentially applying glue to the upper layers allows the iron chips 11 to be directly bonded after cutting to form a motor core, resulting in high automated production efficiency, consistent product quality, and cost savings. Moreover, the automated production process has been achieved, which standardizes the size and gluing process of each group of iron chips 11, ensuring uniform product quality of motor iron cores, facilitating product quality management, and contributing to quality improvement.In addition, by cooperating with the stamping machine and shearing mechanism, a standardized assembly line production process has been achieved, which optimizes the production process, further improves production efficiency, and reduces production costs.
[0054] like Figure 1 , Figure 2 As shown, the frame 100 in this embodiment specifically includes: a base plate 110, a left support 120, a right support 130, a front cover plate 140, a rear cover plate 150, and a top plate 160, forming a square structure. An installation cavity 170 is formed inside the frame 100. A material feed groove 131 is opened on the left support 120 and the right support 130, and the iron core strip 10 moves from left to right within the material feed groove 131. The glue application assembly 200 and the glue application roller 300 are both disposed within the installation cavity 170, where the glue application function is realized.
[0055] like Figure 2 , Figure 3 As shown, the tableting assembly 400 in this embodiment specifically includes: a drive cylinder 410, a push connecting part 420, and a tableting roller 430. The drive cylinder 410 is mounted on the frame 100 and located outside the mounting cavity 170. The piston rod of the drive cylinder 410 extends through the top plate 160 into the mounting cavity 170. The push connecting part 420 is connected to the piston shaft of the drive cylinder 410 and is located inside the mounting cavity 170. The push connecting part 420 moves up and down under the drive of the drive cylinder 410, thus moving the push connecting part 420 closer to or further away from the coating roller 300. The tableting roller 430 is rotatably mounted on the push connecting part 420, and an iron core strip 10 is threaded between the tableting roller 430 and the coating roller 300. When the pressure roller 430 moves downward synchronously by pushing the connecting part 420 downward, it presses the iron core strip 10 located at the conveying position (upper position) down to the coating position (lower position), so that the lower surface of the iron chip 11 contacts the surface of the coating roller 300 for coating. When the pressure roller 430 moves upward synchronously by pushing the connecting part 420 upward, the iron core strip 10 is not subjected to downward pressure, and thus moves upward under the return force of external equipment (such as winding and unwinding equipment) to return to the conveying position for left-to-right movement. By driving the cylinder 410, the pressure roller 430 can move up and down quickly, achieving a relatively agile response. Furthermore, the pressing roller 430 is used to press down the iron core belt 10. Since both the pressing roller 430 and the glue coating roller 300 are rotating, even during the pressing and glue coating process, the iron core belt 10 is subjected to uniform force from top to bottom, the glue coating thickness is uniform, and the iron core belt 10 can move normally left and right, ensuring the stability of the movement of the iron core belt 10.
[0056] like Figure 2 , Figure 3As shown, further, the pushing connection part 420 in this embodiment specifically includes: a pushing horizontal plate 421 and a pushing vertical plate 422. The pushing horizontal plate 421 is horizontally arranged and fixedly connected to the end of the piston rod of the driving cylinder 410. The pushing vertical plate 422 is vertically connected to the pushing horizontal plate 421 and is located at one end of the pushing horizontal plate 421 in the front-rear direction. The pressure roller 430 is rotatably arranged on the pushing vertical plate 422. The pushing horizontal plate 421 and the pushing vertical plate 422 move up and down under the push of the driving cylinder 410. A guide groove 121 is formed on the inner wall of the bracket in the left-right direction, and the guide groove 121 extends a predetermined length in the up-down direction. The left and right ends of the push vertical plate 422 are respectively embedded in the guide grooves 121 on the left and right sides, so that the part of the push vertical plate 422 located in the guide groove 121 forms a guide boss 423. The guide boss 423 is slidably disposed in the guide groove 121, thereby guiding the up and down movement of the entire push connection part 420, so that the pressure roller 430 connected to it can move stably in the up and down direction.
[0057] like Figure 3 As shown, the push vertical plate 422 in this embodiment is square, and its left and right ends can be directly used as guide bosses 423 for guidance. The front and rear sides of the push vertical plate 422 are used to provide support positions for the installation of the tableting roller 430, so that the push vertical plate 422 can both support the tableting roller 430 and guide it, thus optimizing the structure.
[0058] like Figure 2 , Figure 4 As shown, the glue-spreading assembly 200 further includes: a glue storage box 210, a glue-spreading roller 220, and a glue-spreading roller 230. The glue storage box 210 has an opening at its top, and is used to inject glue. The glue storage box 210 is located within the mounting cavity 170. A mounting groove 151 is provided at the lower end of the rear cover plate 150 of the frame 100. A "┐"-shaped frame 212 is fixed to the rear end face and / or front end face of the base plate 110 by screws. The "┐"-shaped frame 212 extends into the mounting cavity 170 through the mounting groove 151, and the glue storage box 210 is fixed to the "┐"-shaped frame 212. Specifically, a lower limiting step is provided on one end of the "┐"-shaped frame 212 located within the mounting cavity 170, and the edge of the glue storage box 210 is embedded in the limiting step to achieve installation and fixation. In addition, if it is necessary to adjust the vertical position of the glue storage box 210, the vertical height of the "U"-shaped frame 212 can be adjusted directly. For example, the hole for fixing the screw on the "U"-shaped frame 212 can be set as an oblong hole extending in the vertical direction, so that the vertical adjustment of the glue storage box 210 can be achieved by matching the screw with the oblong hole.
[0059] like Figure 2 , Figure 4As shown, the glue-applying roller 220 is rotatably mounted on the frame 100 and located within the mounting cavity 170. The glue-applying roller 220 is positioned above the glue storage box 210, and its rotation causes the glue inside the storage box 210 to be rolled up. To ensure uniform glue application on the glue-applying roller 220, it is positioned above the center of the glue storage box 210 in the left-right direction, with a portion of its outer circumference below the plane of the opening of the glue storage box 210. The glue-spreading roller 230 is rotatably mounted on the frame 100, and its outer wall contacts both the outer wall of the glue-applying roller 300 and the glue-applying roller 220 after it has been coated with glue. In the specific structure, the glue-spreading roller 230 is located slightly to the left or right above the glue-spreading roller 220. The rotation direction of the glue-spreading roller 230 is opposite to that of the glue-spreading roller 220. This allows the glue on the glue-spreading roller 220 to be smoothly applied to the glue-spreading roller 230. There is a relatively small gap between the glue-spreading roller 220 and the glue-spreading roller 230, which allows the amount of glue on the glue-spreading roller 230 to be controlled.
[0060] like Figure 2 , Figure 3 , Figure 4 As shown, the coating roller 300 is positioned slightly to the left or right above the leveling roller 230. The rotation direction of the leveling roller 230 is opposite to that of the coating roller 300, allowing the adhesive on the leveling roller 230 to be applied onto the coating roller 300. The rotation of the coating roller 300 during the coating process provides a certain traction force to the iron core belt 10; therefore, the coating roller 300 rotates clockwise from left to right.
[0061] In this embodiment, the leveling roller 230 is offset from directly above the launching roller 220, and the coating roller 300 is also offset from directly above the leveling roller 230. This reduces the structural height and facilitates the structural design of the coating structure within the impact mold. In this embodiment, the leveling roller 230 is offset to the left from directly above the launching roller 220, and the coating roller 300 is offset to the left from directly above the leveling roller 230. This ensures that the leveling roller 230 and coating roller 300 are offset to the same side, preventing residual glue on each roller from falling onto the lower roller and affecting the coating effect.
[0062] like Figure 2 , Figure 4As shown, in this embodiment, the surface of the coating roller 300 is further provided with an adhesive layer 310, the shape of which matches the outline of the iron chip 11. When the coating roller 300 rotates, the outline of the adhesive layer 310 on the horizontal plane is the same as the outline of the iron chip 11. The surface of the adhesive layer 310 is protruding, so that during coating, the adhesive layer is mainly adhered to the adhesive layer. Through the rotation of the coating roller 300 and the movement of the iron core belt 10, the coating is carried out simultaneously, so that the adhesive coverage area on the adhesive layer is completely the same as the surface outline of the iron chip 11, achieving precise coating. This avoids adhesive waste and also prevents other areas of the iron core belt 10 from being glued and interfering with the subsequent iron chip 11 cutting process. After cutting, only the lower surface area of the iron chip 11 is glued, which makes it easier for the iron chips 11 to be stacked and automatically bonded.
[0063] like Figure 2 , Figure 3 As shown, the glue application assembly 200 further includes an adhesive adjusting assembly 240, which is mounted on the frame 100 and used to adjust the adhesive thickness on the glue-applying roller 220. The thickness of the adhesive adhering to the surface of the glue-applying roller 220 can be adjusted by the distance (typically a small gap) between the adhesive adjusting assembly 240 and the surface of the glue-applying roller 220. This allows for control of the amount of glue applied as needed, preventing excessive glue application and waste.
[0064] like Figure 2 , Figure 3 As shown, the glue adjusting assembly 240 further includes: distance adjusting members 250 located on the left and right sides of the glue-applying roller 220, and a glue-blocking plate 241 on each distance adjusting member 250. A glue adhesion space is formed between the glue-blocking plate 241 and the outer wall of the glue-applying roller 220. The glue-blocking plate 241 can move in the left and right direction by adjusting the distance adjusting members 250 to adjust the size of the glue adhesion space. When glue is applied to the outer wall of the glue-applying roller 220 from below, it rotates and passes the glue-blocking plate 241. If the thickness of the glue is greater than the width of the glue adhesion space, the excess glue will be scraped off by the glue-blocking plate 241, thus making the glue thickness on the glue-applying roller 220 equal to the width of the glue adhesion space, achieving the purpose of adjusting the glue thickness.
[0065] like Figure 2 , Figure 3As shown, the distance adjustment component 250 specifically includes: an adjusting horizontal plate 251, an adjusting vertical plate 252, and an adjusting pad 253. The adjusting horizontal plate 251 extends a predetermined length in the left-right direction and passes through the side of the frame 100 to extend into the mounting cavity 170. A baffle plate 241 is disposed on the adjusting horizontal plate 251. The adjusting vertical plate 252 is vertically connected to the adjusting horizontal plate 251 in the up-down direction and is located on the outside of the frame 100. The adjusting vertical plate 252 and the adjusting horizontal plate 251 can be integrally formed, thereby ensuring the structural strength of the entire plate. The adjusting vertical plate 252 is connected to the side of the frame 100 by through screws. An adjusting pad 253 is disposed between the adjusting vertical plate 252 and the side of the frame 100. The screws can pass through the adjusting pad 253 to fix the adjusting pad 253. The thickness of the adjusting pad 253 is pre-configured as needed. By replacing the adjusting pads 253 of different thicknesses, the distance between the adjusting vertical plate 252 and the side of the frame 100 can be changed, thereby changing the width of the adhesive adhesion space.
[0066] An installation step is provided on the end of the adjusting plate 251 facing the glue-applying roller 220. A through hole is provided on the glue-blocking plate 241, which is fixed to the installation step by screws. If it is necessary to adjust the width of the glue adhesion space by adjusting the glue-blocking plate 241, the through hole on the glue-blocking plate 241 can be made into an oblong shape. This allows the position of the glue-blocking plate 241 in the left-right direction to be adjusted through the oblong shape and the screws, thereby changing the width of the glue adhesion space.
[0067] like Figure 1 , Figure 4As shown, the gluing mechanism further includes a drive assembly 500, which specifically includes a drive motor 510, a drive shaft 520, a drive gear 530, a first driven gear 540, and a second driven gear 550. The drive shaft 520 is rotatably connected to the frame 100 via bearings and extends through the frame 100 into the mounting cavity 170. One end of the drive shaft 520 is connected to the drive motor 510, and the other end, located in the mounting cavity 170, is connected to the gluing roller 300. Therefore, when the drive motor 510 is energized, it rotates, driving the drive shaft 520 to rotate, which in turn drives the gluing roller 300 to rotate. A drive gear 530 is connected to a drive shaft 520. A first driven gear 540 is rotatably connected to the frame 100 and meshes with the drive gear 530. A spreading roller 230 is connected to the frame 100 via a bearing seat and passes through the frame 100 to connect with the first driven gear 540. The drive gear 530 drives the first driven gear 540 to rotate, and the first driven gear 540 drives the spreading roller 230 to rotate. A spreading roller 220 is rotatably connected to the frame 100 via a bearing seat and passes through the frame 100 to connect with a second driven gear 550. Thus, the second driven gear 550 is rotatably connected to the frame 100 and meshes with the first driven gear 540. The first driven gear 540 drives the second driven gear 550 to rotate, and the second driven gear 550 drives the spreading roller 220 to rotate. The meshing connection of the drive gear 530, the first driven gear 540 and the second driven gear 550 enables a relatively precise transmission, which allows the adhesive layer 310 on the coating roller 300 to be accurately aligned with the moving iron core belt 10 during rotation, and the glue on the adhesive layer 310 can be accurately coated on the surface of the iron chip 11 on the iron core belt 10.
[0068] Example 2
[0069] This application discloses a motor core manufacturing apparatus, comprising a stamping mechanism, a gluing mechanism as described in Embodiment 1, and a cutting mechanism arranged sequentially in a left-right direction. The core strip moves sequentially from left to right, passing through the stamping mechanism, the gluing mechanism, and the cutting mechanism. The stamping mechanism stamps the core strip to form iron chips arranged in a first direction on the core strip (the iron chips remain attached to the core strip and continue moving with it); the gluing mechanism applies glue to the iron chips on the core strip; the cutting mechanism cuts and stacks the glued iron chips on the core strip, causing them to detach from the core strip and then be sequentially bonded to form the motor core.
[0070] Example 3
[0071] This application proposes a method for manufacturing a motor core, wherein the method for manufacturing a motor core, using the gluing mechanism as described in Embodiment 1, includes the following steps:
[0072] Step S100: Stamp the iron core strip to form iron chips arranged along the first direction on the iron core strip.
[0073] In the specific process, a stamping mechanism is provided, which stamps out iron chips sequentially on the iron core strip by moving the iron core strip (the iron chip is not an independent iron chip, but still has part of its structure connected to the iron core strip, and can move with the iron core strip).
[0074] Step S200: Through the action of the pressing assembly, one iron chip on the iron core belt is in the second state, and several subsequent iron chips are in the first state. The iron core belt cycles between the second state and the first state in sequence. In the second state, one of the iron chips is away from the coating roller and is not coated with glue. In the first state, multiple iron chips continuously abut against the coating roller and are coated with glue.
[0075] In the specific process, through the action of the pressing assembly of the gluing mechanism, the bottommost iron chip in a single motor core is in the second state and no glue is applied to the bottom, while the bottom of the second to Nth layers of iron chips in a single motor core is in the first state and glue is applied.
[0076] Step S300: Cut the iron core strip and separate the iron chips from the iron core strip in sequence, so that the iron chips without glue in the first state form the bottom iron core and the iron chips with glue in the second state are stacked and bonded in sequence.
[0077] In the specific process, the iron chips on the core strip are cut into complete and independent iron chips. The bottom layer of iron chips is not coated with glue, while the upper layers are coated with glue and stacked sequentially, automatically bonding together to form the motor core. The bottom layer of iron chips for the next motor core is not coated with glue, thus preventing the individual motor cores from sticking together and allowing them to separate automatically.
[0078] The above process continues, thus forming an assembly line production line to continuously produce motor cores, greatly improving production efficiency.
[0079] In summary, the gluing mechanism, motor core manufacturing equipment, and manufacturing method disclosed in this solution not only apply glue by passing the core strip through the frame and allowing the iron chips on the core strip to pass through the frame sequentially for gluing, but also, during the gluing process, the glue is first stirred and transferred evenly by a glue-spreading component. Then, a glue-spreading roller and a pressing component work together to apply glue to a predetermined number of subsequent iron chips without applying glue to one chip. Subsequently, the core strip is cut, causing the iron chips to detach sequentially. The un-glued iron chips form the bottom layer of the core, while the subsequent glued iron chips are stacked and bonded together to form the motor core. This achieves the function of automatically applying glue to the bottom layer of iron chips without applying glue, while applying glue to the upper layers sequentially. This allows the cut iron chips to be directly bonded to form a motor core, resulting in high automated production efficiency, consistent product quality, and cost savings.
[0080] It should be understood that the application of this application is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
