Description

Technical Field

[0001] This invention relates to the field of linear motor manufacturing technology, and more specifically, to a high-precision automatic magnetizing device for a high-thrust stator. Background Technology

[0002] High-thrust linear motors are widely used in precision machining, semiconductor manufacturing, and high-end equipment. Their stators mainly consist of a stator base plate and powerful magnets arranged in an array on the stator base plate. During the stator assembly process, two magnets arranged one after the other in the same guide slot repel each other because they have the same polarity, while magnets in adjacent guide slots attract each other because they have opposite polarities. These two drastically different magnetic field characteristics make the magnet bonding process face a complex stress environment.

[0003] Currently, stator magnet bonding is mostly done manually. When operators handle and place magnets, the strong magnetic force of the magnets makes it easy for them to instantly attract and pinch fingers, causing accidents. At the same time, the repulsive force between magnets in the same guide groove makes it difficult to press the magnets stably into the predetermined position before the adhesive cures, resulting in inconsistent bonding accuracy and low work efficiency. Furthermore, the opposing attraction between magnets in adjacent guide grooves after bonding causes the product to adhere tightly to the tooling partition, making manual demolding difficult and prone to damage. Therefore, achieving automation, high precision, and safety in stator magnet bonding is a pressing technical problem that needs to be solved in this field. Summary of the Invention

[0004] The main objective of this invention is to provide a high-precision automatic magnetizing device for high-thrust stators, so as to solve the technical problems of high safety risks, poor bonding accuracy and difficult demolding in the prior art of manual magnetizing.

[0005] To achieve the above objectives, according to one aspect of the present invention, a high-precision automatic magnetizing device for a high-thrust stator is provided, comprising: a guide platform, mounted in the middle of the device via support legs, the guide platform having multiple guide grooves arranged in an array inside, and a positioning step at the bottom of the guide platform; a first linear module, arranged along the arrangement direction of the guide grooves; a second linear module, distributed parallel to the first linear module; a magnet pushing mechanism, mounted on the first linear module mover of the first linear module, for pushing the magnets to be magnetized one by one into the guide grooves; and a stator base plate loading and unloading mechanism, mounted on the second linear module mover of the second linear module, for carrying the stator base plate and feeding it directly below the guide platform. The stator base plate loading and unloading mechanism includes a stator base plate support platform, a preliminary positioning rod that moves through the stator base plate support platform, a clamping block, and a lifting cylinder that drives the stator base plate support platform to rise and fall. After the stator base plate support platform rises to the bottom of the guide platform, the stator base plate is released from the limit of the preliminary positioning rod and pushed by the clamping block to fit tightly against the positioning step to complete the fine positioning. The pressure holding mechanism is located on one side of the guide platform and is used to overcome the like repulsion force between adjacent magnets in the same guide groove after the magnet to be attached is pushed into the guide groove. The demolding mechanism is located above the guide platform and is used to apply a downward pushing force after all the magnets to be attached are attached to overcome the opposite attraction force between the magnets and the partitions in the adjacent guide grooves, and push the stator base plate together with the magnets out of the guide groove as a whole.

[0006] As a preferred embodiment of the present invention, the magnet pushing mechanism includes a ball screw slide, a lifting support plate disposed on the ball screw slide, a pushing translation cylinder mounted on the lifting support plate, a translation block connected to the piston end of the pushing translation cylinder, a magnet pushing cylinder mounted on the translation block, a pushing stop block connected to the piston end of the magnet pushing cylinder, and a magnet hopper mounted at the front end of the translation block. The ball screw slide is driven by a Z-axis lifting motor to adjust the vertical height of the magnet hopper. Through the series combination of multiple kinematic pairs, the magnet pushing mechanism can achieve precise addressing and pushing of the magnet to be attached in both the vertical and horizontal directions.

[0007] As a preferred embodiment of the present invention, the bottom of the inner cavity of the magnet hopper forms an open adhesive-free cavity along the feeding direction. The magnet hopper supports the magnet to be attached only through its solid edges on both sides. The bottom surface of the magnet to be attached is coated with adhesive and suspended above the adhesive-free cavity. This structure effectively prevents the adhesive from being scraped to the bottom of the hopper during the pushing process, causing it to scab and jam.

[0008] As a preferred technical solution of the present invention, the pressure holding mechanism includes a fixed block, a pressure holding cylinder mounted on the fixed block, a pressure holding block connecting plate connected to the piston end of the pressure holding cylinder, and a U-shaped pressure holding block mounted on the pressure holding block connecting plate. When the piston rod of the pressure holding cylinder retracts, the U-shaped pressure holding block is driven to move horizontally along the pushing direction of the magnet to be attached to the corresponding position of the guide groove through the pressure holding block connecting plate.

[0009] As a preferred technical solution of the present invention, the upper part of the U-shaped pressure block passes over the top surface of the magnet to be attached to form a top pressing surface, and the inner vertical arm of the U-shaped pressure block abuts against the front end surface of the magnet to be attached to form an end face limit. The U-shaped pressure block simultaneously constrains the magnet to be attached through the top pressing surface and the end face limit, thereby effectively overcoming the like repulsion force between magnets in the same slot and preventing the magnet from tilting or shifting.

[0010] As a preferred technical solution of the present invention, the U-shaped pressure holding block has a clearance gap in the middle. When demolding, the demolding pressure block of the demolding mechanism passes through the clearance gap and presses down on the magnet to be attached, thus realizing the anti-interference cooperation between pressure holding and demolding in a narrow space.

[0011] As a preferred embodiment of the present invention, the demolding mechanism includes a demolding bracket installed above the guide table, a demolding cylinder installed on the demolding bracket, and a demolding pressure block connected to the piston end of the demolding cylinder. The demolding pressure block is made of Teflon material to prevent damage to the magnet or the surface of the stator base plate during the demolding process.

[0012] As a preferred technical solution of the present invention, the stator base plate loading and unloading mechanism further includes a lifting plate, a clamping cylinder mounted on the lifting plate, and a clamping block connecting plate connecting the clamping cylinder and the clamping block. The lifting cylinder is mounted on the lifting plate and drives the stator base plate support platform to move up and down.

[0013] As a preferred technical solution of the present invention, the bottom end of the preliminary positioning rod is fixed on the base of the stator base plate loading and unloading mechanism and moves through the stator base plate support platform. During the process of the stator base plate support platform rising, the stator base plate slides vertically along the preliminary positioning rod until it breaks away from its limit and becomes a free floating state. Then, it is re-clamped by the clamping cylinder and pushed to the positioning step to complete the precise positioning.

[0014] As a preferred technical solution of the present invention, the main structure of the equipment is made of aluminum to prevent the magnet from being attracted by the equipment structure during transportation and pushing, and the demolding block that directly contacts the magnet to be attached is made of Teflon material to prevent the product from being crushed.

[0015] Compared with existing technologies, this invention achieves precise positioning and bonding of the magnet to be bonded within the guide groove by using a moving system composed of a first linear module and a second linear module, guide grooves arranged in an array on the guide platform, and secondary precision positioning by the stator base plate loading and unloading mechanism. At the same time, the U-shaped pressure block of the pressure holding mechanism moves horizontally along the pushing direction to constrain the magnet from both the top and end faces, effectively overcoming the like-pole repulsion force between adjacent magnets in the same guide groove. Furthermore, the demolding pressure block of the demolding mechanism applies downward force through the clearance of the U-shaped pressure block, overcoming the opposite-pole attraction force between the magnet and the partition between adjacent guide grooves. The entire process requires no manual intervention, eliminating the safety hazard of magnets pinching and injuring operators in traditional manual magnet bonding operations, and significantly improving bonding accuracy and production efficiency.

[0020] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0021] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0022] like Figure 1 and Figure 2As shown in this embodiment, a high-precision automatic magnetizing device for a high-thrust stator is provided, mainly including a magnet pushing mechanism 1, a guide table 2, a pressure holding mechanism 3, a stator base plate loading and unloading mechanism 4, a demolding mechanism 5, a first linear module 6, and a second linear module 7. The first linear module 6 is horizontally arranged along the arrangement direction of the guide grooves 201, and the second linear module 7 is parallel to the first linear module 6, providing a motion basis for the multi-station addressing of the whole machine. The magnet pushing mechanism 1 is mounted on the first linear module mover 601 of the first linear module 6, and can move stepwise along the axial direction of the first linear module 6 to push the magnets into each guide groove 201 in sequence. The stator base plate loading and unloading mechanism 4 is mounted on the second linear module mover 701 of the second linear module 7, and can send the stator base plate b into the area directly below the guide table 2 or remove it from the working area along the axial direction of the second linear module 7. The main structure of the equipment is mostly made of aluminum to prevent the strong magnets from being attracted by the equipment structure during transportation and pushing, thus affecting normal operation.

[0023] like Figure 4 As shown, the guide platform 2 is mounted in the middle of the equipment via support legs 202, spanning the intersection area of ​​the first linear module 6 and the second linear module 7. It remains stationary during operation, serving as a spatial reference for the entire magnetizing process. The guide platform 2 has multiple guide slots 201 arranged in an array inside. These slots are parallel to each other and evenly spaced, with adjacent slots separated by partitions. The cross-sectional shape of each guide slot 201 matches the external dimensions of the magnet a to be magnetized, providing physical guidance for the magnet's insertion trajectory. The bottom of the guide platform 2 has a positioning step 203, which serves as a precision positioning reference surface after the stator base plate b is raised. This positioning surface is precision-machined to ensure positioning accuracy.

[0024] like Figure 3 As shown, the magnet pushing mechanism 1 is mounted on the first linear module mover 601. The magnet pushing mechanism 1 includes a ball screw slide 101, driven by a Z-axis lifting motor 107, capable of precise vertical lifting. A lifting support plate 102 is mounted on the sliding component of the ball screw slide 101 and rises and falls synchronously. A pushing translation cylinder 103 is mounted on the lifting support plate 102, with its piston end connected to a translation block 105. When the pushing translation cylinder 103 extends, it drives the translation block 105 to move horizontally towards the guide platform 2. A magnet pushing cylinder 104 is mounted on the translation block 105, with its piston end connected to a pushing stop 106. A magnet hopper 108 is mounted at the front end of the translation block 105 and is used to load the magnets a to be attached, with glue applied to the bottom.

[0025] The bottom structure of the magnet hopper 108 is unique. Its inner bottom is not a completely closed plane, but rather an open, glue-avoiding cavity formed along the feeding direction, with the magnet to be attached supported only by the solid edges on both sides. Since the bottom surface of the magnet to be attached is pre-coated with instant adhesive, if a completely flat-bottomed hopper structure were used, the adhesive on the bottom surface would be squeezed and overflowed during the pushing process, easily forming a crust on the inner wall of the hopper and causing subsequent pushing to become stuck. This edge-supported, centrally suspended design ensures that the adhesive surface remains suspended and free throughout the pushing process, until the magnet is pushed into the guide groove 201 and then contacts the surface of the stator base plate b. The entire magnet pushing mechanism 1 thus forms a three-stage series motion pair: the first stage uses the Z-axis lifting motor 107 to drive the ball screw slide 101 to achieve precise vertical alignment; the second stage uses the pushing translation cylinder 103 to achieve horizontal forward and backward movement; and the third stage uses the magnet pushing cylinder 104 to achieve the final pushing stroke.

[0026] like Figure 7 and Figure 8 As shown, the stator base plate loading and unloading mechanism 4 is mounted on the second linear motion actuator 701. The stator base plate loading and unloading mechanism 4 includes a stator base plate support 401, a preliminary positioning rod 402, a clamping block 403, a lifting plate 404, a clamping cylinder 405, a clamping block connecting plate 406, and a lifting cylinder 407. The lifting plate 404 serves as the mounting base for the various functional components inside the stator base plate loading and unloading mechanism 4. The lifting cylinder 407 is mounted on the lifting plate 404, and its piston end is connected to the stator base plate support 401 to drive the stator base plate support 401 to perform vertical lifting and lowering movements. The bottom end of the preliminary positioning rod 402 is fixed to the base structure below the lifting plate 404, and the rod moves upward through a pre-set through hole on the stator base plate support 401. The clamping cylinder 405 is also mounted on the lifting plate 404 and is connected to the clamping block 403 via the clamping block connecting plate 406.

[0027] In the initial feeding stage, the stator base plate b is placed on the stator base plate support platform 401. At this time, the rod of the preliminary positioning rod 402 passes through the support platform 401 and extends into the corresponding hole on the stator base plate b, restricting the stator base plate b between the clamping block 403 and the preliminary positioning rod 402, completing the preliminary positioning with relatively low accuracy. This preliminary positioning is mainly used to prevent the stator base plate b from moving significantly on the support platform 401 during the high-speed translation of the second linear mold mover 701. The second linear mold mover 701 drives the entire stator base plate loading and unloading mechanism 4 to translate to directly below the guide table 2 and then stops. Subsequently, the lifting cylinder 407 is activated, driving the stator base plate support platform 401 to move upward. Since the bottom end of the preliminary positioning rod 402 is fixed on the lower base and moves through the support platform 401, during the upward movement of the support platform 401, the stator base plate b slides upward relative to the preliminary positioning rod 402, gradually breaking away from the limiting constraint of the preliminary positioning rod 402 on the stator base plate b. When the stator base plate support 401 carries the stator base plate b to near the bottom of the guide platform 2, the stator base plate b has already broken free from the constraint of the initial positioning rod 402 and is in a free-floating state. At this time, the clamping cylinder 405 drives the clamping block 403 to move again through the clamping block connecting plate 406, pushing the free-floating stator base plate b to produce a slight translation in the horizontal plane, so that the reference side of the stator base plate b is in close contact with the positioning step 203 at the bottom of the guide platform 2. Through the above combination of purely mechanical actions of first coarse positioning, then suspension and pressure relief, and then forced precise positioning, the positional deviation accumulated by the second linear motion element 701 during long-distance transportation and the machining tolerance of the stator base plate b itself are completely eliminated, providing an absolutely reliable reference surface for the high-precision bonding of the magnet in the guide groove 201.

[0028] like Figure 4 and Figure 5As shown, the pressure-holding mechanism 3 is located slightly below one side of the guide platform 2. The pressure-holding mechanism 3 includes a fixed block 303, a pressure-holding cylinder 304, a pressure-holding block connecting plate 302, and a U-shaped pressure-holding block 301. The fixed block 303 is rigidly mounted on the support leg 202 of the guide platform 2 or a related fixed structure. The pressure-holding cylinder 304 is mounted on the fixed block 303, and its piston end is connected to the U-shaped pressure-holding block 301 via the pressure-holding block connecting plate 302. The U-shaped pressure-holding block 301 is located near the opening on one side of the guide groove 201 of the guide platform 2. When the piston rod of the pressure-holding cylinder 304 retracts, the pressure-holding block connecting plate 302 pulls the U-shaped pressure-holding block 301 horizontally along the pushing direction of the magnet a to be attached, causing the U-shaped pressure-holding block 301 to enter the corresponding position in the guide groove 201. The U-shaped pressure-holding block 301 has a unique design: it is L-shaped when viewed from the side and U-shaped when viewed from above. When the U-shaped pressure block 301 moves forward into position, its upper part passes over the top surface of the magnet a to be attached, forming a top pressing surface, and its inner vertical arm abuts against the front end surface of the magnet a to be attached, forming an end face limit. Through the synergistic effect of these two contact surfaces, the U-shaped pressure block 301 prevents the magnet from being lifted upwards due to like-pole repulsion and also prevents it from sliding out in the reverse direction along the pushing direction, maintaining a closed-loop force during the pressure holding period. The bottom of the U-shaped pressure block 301 is provided with a slope to facilitate better sliding into the magnet from above to form a pressing effect. The middle of the U-shaped pressure block 301 has a clearance gap, which is directly opposite the central axis of the magnet in the guide groove 201. Its purpose is to provide a passage for the demolding block 503 of the subsequent demolding mechanism 5, so that the pressure holding and demolding processes can be switched without interference in the same small space.

[0029] like Figure 2 and Figure 3 As shown, the demolding mechanism 5 is located above the guide table 2. The demolding mechanism 5 includes a demolding bracket 501, a demolding cylinder 502, and a demolding pressure block 503. The demolding bracket 501 is fixedly installed in the upper area of ​​the guide table 2, and the demolding cylinder 502 is installed on the demolding bracket 501, with its piston end connected to the demolding pressure block 503. The demolding pressure block 503 is made of Teflon material, which has an extremely low coefficient of surface friction and excellent self-lubricating properties, preventing indentations or damage to the magnet surface or the stator base plate b surface during demolding.

[0030] The complete workflow of the equipment in this embodiment is as follows. After the equipment is powered on and supplied with air, each motion module first performs the initialization action of finding the mechanical origin. The first linear module mover 601 returns to the initial position, and the second linear module mover 701 returns to the loading and unloading position. After the operator or the preceding automated mechanism places the stator base plate b on the stator base plate support platform 401 and completes the initial positioning, the control system sends a signal, and the second linear module mover 701 drives the stator base plate loading and unloading mechanism 4 to move along the second linear module 7 to directly below the guide platform 2 and stop in place. The lifting cylinder 407 is activated, lifting the stator base plate support platform 401 and the stator base plate b upward. During the upward process, the stator base plate b gradually gets out of the constraint of the initial positioning rod 402. After it is in place, the clamping cylinder 405 clamps it again, pushing the stator base plate b to fit tightly against the positioning step 203 to complete the fine positioning.

[0031] After precise positioning, the magnet pushing operation begins. The pre-application adhesive mechanism loads the magnet a, with its bottom surface coated with instant adhesive, into the magnet hopper 108. The first linear module mover 601 drives the magnet pushing mechanism 1 to move to the position corresponding to the first guide groove 201. The Z-axis lifting motor 107 drives the ball screw slide 101 to adjust the height, so that the outlet of the magnet hopper 108 is aligned with the inlet of the guide groove 201. At this time, the height of the hopper outlet is slightly higher than the guide groove 201 to avoid spatial interference with the U-shaped pressure block 301. The pushing translation cylinder 103 extends, driving the translation block 105 and the magnet hopper 108 to move forward to the inlet of the guide groove 201. The magnet pushing cylinder 104 is activated, and the pushing stop 106 pushes the first magnet a to be attached in the magnet hopper 108 along the guide groove 201 to its bottom. When the first magnet enters, it is not affected by the repulsive force of like poles. After being pushed to the bottom, it can be attracted and adhered by the attraction force of the stator base plate b itself. No pressure holding is required at this stage. The magnet pushing cylinder 104 and the material pushing translation cylinder 103 return to their original positions in sequence.

[0032] Subsequently, the preceding mechanism reloads the next magnet to be attached, 'a', into the magnet hopper 108. The pusher cylinder 103 extends again, and the pusher cylinder 104 pushes the second magnet to be attached, 'a', into the same guide groove 201. Since the two magnets in the same guide groove 201 have the same polarity, the second magnet, upon entering, is subjected to a strong repulsive force and tends to be ejected. At this time, the pusher block 106 remains at the entrance of the guide groove 201 without reversing, continuously pressing the second magnet to prevent it from being ejected by the repulsive force. Simultaneously, the pressure-holding cylinder 304 actuates, the piston rod retracts, and the pressure-holding block connecting plate 302 pulls the U-shaped pressure-holding block 301 horizontally along the pushing direction to the position of the guide groove 201. The upper part of the U-shaped pressure-holding block 301 slides in from above the top surface of the magnet, and the inner vertical arm abuts against the front end face of the magnet, forming a double constraint of top surface pressing and end surface limiting. Only then can the pusher block 106 return and exit, and the magnet is completely pressured by the U-shaped pressure-holding block 301. The U-shaped pressure-holding block 301 maintains pressure for a period of time, allowing the instant adhesive on the bottom surface of the magnet to fully cure under pressure, firmly bonding the magnet to the stator base plate b. After pressure holding is completed, the piston rod of the pressure-holding cylinder 304 extends, and the U-shaped pressure-holding block 301 retracts to its original position. The first linear module mover 601 steps to the position corresponding to the next guide groove 201, repeating the above pushing and pressure-holding actions until all magnets in all guide grooves 201 have been pushed and pressure-held.

[0033] After all the bonding work is completed, the magnets in the adjacent guide grooves 201 are attracted to each other due to their opposite polarities, and the magnets are tightly adhered to the partition between the guide grooves 201. At this time, even if the lifting cylinder 407 drives the stator base plate support platform 401 to descend, the stator base plate b is already bonded to the magnet with glue, and the magnet is attracted by the partition, so the entire product is still suspended at the bottom of the guide platform 2 and cannot fall naturally by gravity. At this time, the demolding mechanism 5 is activated, and the demolding cylinder 502 drives the Teflon demolding block 503 to move downward, passing through the clearance in the middle of the U-shaped pressure block 301, and directly pressing against the magnet in the guide groove 201. The demolding cylinder 502 continues to apply downward thrust, overcoming the attraction between the magnet and the guide groove partition, and pushes the stator base plate b and the magnet bonded on it downward out of the guide groove 201, so that the finished product falls smoothly back onto the stator base plate support platform 401 that has descended and is waiting below. After the demolding block 503 is reset, the second linear mold mover 701 drives the stator base plate loading and unloading mechanism 4, which is loaded with finished products, to move out of the working area from below the guide table 2. The operator or subsequent automated mechanism takes away the finished products, and the entire magnetizing operation cycle is completed.

[0034] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art.
