Description

Technical Field

[0001] This invention relates to the technical field of misaligned magnetic arrangement, and specifically to a Heilbeck array misaligned magnetic arrangement device. Background Technology

[0002] Helbeck array magnetic components, with their high-intensity and highly uniform magnetic field on one side, have become core magnetic components in high-end fields such as micro-motors, precision sensors, and biomedical devices. As downstream products move towards miniaturization and lightweighting, stringent requirements are placed on the precision of magnet arrangement and mass production efficiency. Helbeck arrays require arranging and bonding multiple sets of micro-magnets with different magnetic pole orientations according to a preset misalignment rule. Existing magnet loading processes (i.e., the process of transporting magnets of the same pole from their respective storage compartments to the bonding area via conveyor belts) often use a piece-by-piece method, pushing individual magnets onto the conveyor belt, which cannot achieve synchronous loading of multiple magnets of the same pole, resulting in low mass production efficiency. Existing technologies related to magnet arrangement are disclosed in the Chinese patent database. For example, CN223927198U discloses a magnet pushing and arranging fixture; and CN223140491U discloses a magnet arrangement structure.

[0003] The aforementioned prior art (CN223927198U, CN223140491U) does not disclose how to push multiple magnets onto the conveyor belt in batches. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a Heilbeck array misaligned magnetic arrangement device to solve the problem of how to push multiple magnets onto a conveyor belt in batches.

[0005] This invention discloses a Hellbeck array magnetic alignment device, comprising a base, an operating box fixedly installed on the upper surface of the base, and an internally formed closed receiving cavity; a bonding platform fixedly connected to the geometric center of the bottom plate of the receiving cavity, with a bonding positioning station on the upper surface for bonding and positioning of the Hellbeck array magnetic components; multiple curved conveyors arranged around the bonding platform and fixed to the bottom plate of the receiving cavity; the discharge ends of the multiple curved conveyors are connected to the corresponding feeding stations of the bonding platform, with the feeding ends extending outwards from the receiving cavity, and a Hall magnetic pole detection sensor for detecting the polarity of the flowing magnets is installed in the middle section of the conveying channel; a pusher storage mechanism is set one-to-one with the curved conveyors, fixed to the bottom plate of the receiving cavity, with the discharge port connected to the feeding end of the corresponding curved conveyor, for temporary storage and batch pushing of magnets; a multi-axis robotic arm is set inside the receiving cavity, with an operating radius covering the feeding stations of all pusher storage mechanisms, the magnetic pole detection and rejection stations of all curved conveyors, and the bonding platform.

[0006] Specifically, the material pushing and temporary storage mechanism includes a machine base. A horizontally continuous placement groove is formed on the side wall of the machine base, and a vertical groove is also formed inside the machine base. The lower end of the vertical groove communicates with the top of the placement groove cavity. A guide plate is vertically embedded in the vertical groove, with its lower end extending above the placement groove cavity. One side wall of the guide plate is integrally formed with multiple vertically distributed limiting channels in a linear array, the lower ends of which are all connected to the placement groove cavity. The placement groove cavity contains multiple horizontally extending sliding channels arranged in a linear array. The grooves, slides, and limiting channels correspond one-to-one; the vertical height inside the groove cavity is greater than the vertical height of a single magnet to be pushed, but less than the total vertical height of two magnets to be pushed; an electric cylinder is fixedly installed at one end of the groove cavity, the cylinder body of the electric cylinder is fixed to the machine base, and the sliding output end of the electric cylinder is arranged in the direction of extension of the groove; multiple push-pull rods arranged in a linear array are fixed on the slider of the electric cylinder, and each push-pull rod slides and adapts to the groove cavity of the corresponding groove.

[0007] The optimized design features fixed seats fixedly installed on the upper end face of the machine tool and on the left and right sides of the vertical groove. The inner side walls of the two sets of fixed seats respectively abut against and limit the left and right side walls of the guide plate and are fixedly connected to it, which is used to reinforce the guide plate and limit its radial movement.

[0008] In the optimized version, a sealing plate is also attached to the side of the guide plate with the limiting channel. The surface of the sealing plate completely covers the lateral openings of all the limiting channels. The sealing plate, guide plate and limiting channels work together to form a closed storage cavity with an upper opening and a lower end connected to the placement groove, which is used to prevent the magnet from coming out of the lateral opening of the limiting channel.

[0009] Specifically, the top panel of the control box is equipped with a controller, which integrates a display unit and operation buttons; the base includes a support frame; the upper end of the support frame is fixed to the bottom end of the control box, and casters are installed at the four corners of the bottom frame of the support frame; a fixed foot is also provided on the bottom frame of the support frame at the position corresponding to each caster, and the fixed foot is connected to the support frame by a threaded connection.

[0010] Specifically, the bonding platform includes a storage platform. The storage space is formed by the end of the conveying channels of multiple curved conveyors. The storage platform is set within the storage space and is used to support the bonding carrier. The upper surface of the bonding carrier has a groove, which corresponds one-to-one with the number and arrangement of magnets in the Helbeck array magnetic components to be formed. It is used to receive magnets of different polarities conveyed by the curved conveyors in different directions. Each curved conveyor has a support frame fixed at the end of its conveying channel. The support frame is equipped with a glue spray head. The glue spray heads are interconnected by rigid glue delivery pipes. The glue delivery pipes are equipped with glue inlets. The glue inlets are connected to a glue cylinder storing adhesive through a guide pipe. This is used to divert the adhesive to each glue spray head. The glue outlet of each glue spray head is positioned opposite to the edge of the corresponding groove of the bonding carrier on the storage platform.

[0011] The optimized design features an electric telescopic cylinder embedded in the shelf, which provides the telescopic driving force. The output end of the electric telescopic cylinder is fixed with a positioning block. The bottom of the bonding carrier has a square groove that corresponds to and matches the positioning block. The positioning block and the square groove are positioned opposite each other and can be plugged in to form a dedicated positioning structure for the bonding carrier.

[0012] The beneficial effects of this invention are as follows: This invention primarily addresses the problem of how to batch-push multiple magnets onto a conveyor belt. By utilizing the coordination of limiting channels, chutes, and multiple sets of push-pull rods in the material feeding temporary storage mechanism, this application enables the synchronous pushing of multiple magnets with the same pole, providing a stable and continuous batch material supply for the curved conveyor and significantly improving magnet feeding efficiency. By limiting the vertical height of the chutes, only one magnet is output per pushing action, effectively preventing the simultaneous removal of stacked magnets from the upper layers, eliminating the possibility of multiple magnets getting stuck or misaligned during output, and ensuring the accuracy and orderliness of the output process. Combined with a Hall effect magnetic pole detection sensor on the curved conveyor, the polarity of the flowing magnets can be identified in real time, and magnets with opposite poles can be rejected, ensuring that the polarity of the magnets entering the bonding station meets preset requirements, significantly improving the finished product qualification rate of the Heilbeck array magnetic components. By combining a multi-axis robotic arm and a bonding platform, the entire process from batch feeding and polarity screening to array bonding is automated, reducing errors caused by manual intervention and improving assembly accuracy and production efficiency.

[0029] To clearly understand the technical solution of this application, the following will describe in detail a Heilbeck array misaligned magnetic arrangement device provided by this application in conjunction with specific embodiments and accompanying drawings.

[0030] Example 1: This example provides a Hellbeck array misaligned magnetic arrangement device, referenced... Figures 1 to 2 , Figure 1 The diagram shown is a schematic representation of the overall structure of the present invention, while Figure 2The diagram shows a partial structural schematic of the present invention. As can be seen, the device includes a base 1, which serves as the basic mounting reference for the device. The bottom end face of the operating housing 2 is fixedly mounted to the upper end face of the base 1 using bolts. The operating housing 2 has a closed receiving cavity 3 formed inside. The horizontal bottom plate of the receiving cavity 3 provides a unified, coplanar mounting reference surface for all internal functional components. A bonding platform is provided at the geometric center of the receiving cavity 3. The lower end face of the bonding platform is fixedly connected to the bottom plate of the receiving cavity 3 using locating pins and bolts. The upper end face of the bonding platform has a bonding positioning station that matches the contour of the Hellbeck array magnetic components, serving as the final working reference for bonding the magnetic array. Three curved conveyors 4 (existing mature products; other numbers of curved conveyors 4 can be installed according to actual needs) are arranged in a circular, equidistant array around the geometric center of the bonding platform. The lower end of the frame of each curved conveyor 4 is fixedly connected to the bottom plate of the receiving cavity 3 by bolts. The discharge end (the end closest to the bonding platform) of each curved conveyor 4 precisely aligns with the corresponding feeding station on the periphery of the bonding platform, ensuring a smooth connection between the end of the conveying channel of the curved conveyor 4 and the bonding positioning station of the bonding platform. The feeding end (the end furthest from the bonding platform) of each curved conveyor 4 extends outwards towards the receiving cavity 3, aligning with the discharge port of a corresponding pusher storage mechanism. The lower end of the base 6 of the pusher storage mechanism is fixedly connected to the bottom plate of the receiving cavity 3 by bolts. At least one set of Hall effect magnetic pole detection sensors is fixedly installed in the middle section of the conveying channel of each curved conveyor 4. The detection area of ​​the Hall effect magnetic pole detection sensors completely covers the magnet passage path in the conveying channel, and can detect the magnetic pole polarity of the magnet flowing through it in real time. A multi-axis robotic arm (directly adopting existing mature technology, not shown in the attached figure) is also installed in the receiving cavity 3. The working radius of the end effector of the multi-axis robotic arm completely covers the material loading station of the storage cavity 13 of all pushing temporary storage mechanisms, the magnetic pole detection rejection station of all curved conveyors 4, and the bonding platform.

[0031] The general workflow of the Heilbeck array misaligned magnetic alignment device is as follows: In the feeding stage, the multi-axis robotic arm loads a large number of magnets with the same pole into the storage chamber 13 of the three pusher temporary storage mechanisms according to the preset magnetic pole requirements, thus completing the batch feeding of magnets with the same pole at a single station. In the synchronous feeding stage, the feeding components of the three feeding temporary storage mechanisms operate synchronously, pushing the four same-pole magnets in the storage chamber 13 to the feeding channel of the corresponding curved conveyor 4. In the magnetic pole detection and rejection process, the magnet is conveyed forward by the conveyor belt of the curved conveyor 4. When it passes through the detection area of ​​the Hall magnetic pole detection sensor, the sensor identifies the polarity of the magnet in real time. If a magnet with an opposite pole that does not meet the preset requirements is detected, the multi-axis robotic arm immediately moves to remove the magnet with an opposite pole that does not meet the preset requirements from the conveying channel of the curved conveyor 4. In the bonding and molding process, magnets of the same polarity that meet the polarity requirements are conveyed to the end via curved conveyor 4 and precisely fed into the corresponding feeding station of the bonding platform. After all magnets in the three directions have been delivered to the preset position of the bonding platform, the bonding and fixing of the magnets is completed, and the Heilbeck array magnetic component is finally obtained.

[0032] For details, please refer to Figures 3 to 4 ,in, Figure 3 The diagram shown is a first-view structural schematic of the material feeding and storage mechanism. Figure 4 The diagram shows a second-view structural schematic of the material pushing and storing mechanism. As can be seen, the mechanism includes a machine base 6, which serves as the core mounting base. Its lower end is fixedly connected to the bottom plate of the receiving cavity 3 of the operating box 2 via bolts. A horizontally extending placement groove 7 is formed on the side wall of the machine base 6. A vertical groove 8 is also formed inside the machine base 6. The lower end of the vertical groove 8 communicates with the top of the cavity of the placement groove 7, and the extension direction of the vertical groove 8 is perpendicular to the extension direction of the cavity of the placement groove 7. (Continue to refer to...) Figure 5 The diagram shows the installation of guide plate 9 and sealing plate 12. As can be seen, guide plate 9 is vertically embedded in vertical groove 8, with its lower end extending above the cavity of placement groove 7. Four vertically distributed limiting channels 10 are integrally formed on one side wall of guide plate 9 in a linear array. The lower ends of all four limiting channels 10 communicate with the cavity of placement groove 7, forming a vertical material discharge channel for the magnet. Fixing seats 11 are fixedly installed on the upper surface of machine base 6, located on the left and right sides of vertical groove 8. The opposing inner walls of the two sets of fixing seats 11 abut against and are fixedly connected to the left and right side walls of guide plate 9, respectively, for structural reinforcement and radial limiting of guide plate 9, preventing positional displacement of guide plate 9 during operation. Figure 5As shown, a sealing plate 12 is also attached to one side of the guide plate 9 where the limiting channels 10 are located. The surface of the sealing plate 12 completely covers the lateral openings of the four limiting channels 10. The sealing plate 12, together with the guide plate 9 and the limiting channels 10, forms a closed storage cavity 13 with an upper opening and a lower end connected to the placement groove 7. This prevents the magnet from coming out of the lateral opening of the limiting channel 10, ensuring that the magnet can only fall vertically downwards along the limiting channel 10. Inside the placement groove 7, four horizontally extending chutes 14 are fixedly arranged in a linear array. The four chutes 14 correspond one-to-one with the four limiting channels 10. The feed end of each chutes 14 is precisely connected to the lower discharge port of the corresponding limiting channel 10, allowing the magnet in the limiting channel 10 to fall vertically into the corresponding chutes 14. The vertical height inside the chute 14 is limited to being greater than the vertical height of a single magnet to be pushed, but less than the total vertical height of two magnets to be pushed. This structural limitation ensures that only one magnet can be accommodated in a single chute 14 at a time, completely preventing the upper magnet from being carried out synchronously with the lower magnet. This guarantees that only one magnet can be output in each pushing action, achieving precise and orderly discharge of a single magnet and eliminating the risk of multiple magnets getting stuck or misaligned during discharge. An electric cylinder 15 is fixedly installed at one end of the cavity of the placement slot 7. The cylinder body of the electric cylinder 15 is fixedly connected to the machine base 6. The sliding output end of the electric cylinder 15 is arranged in the extension direction of the slide 14. Four push-pull rods 16 arranged in a linear array are fixedly connected to the slider of the electric cylinder 15. The four push-pull rods 16 correspond one-to-one with the four slides 14. Each push-pull rod 16 slides and adapts to the cavity of the corresponding slide 14. The electric cylinder 15 can drive the four push-pull rods 16 to slide horizontally back and forth along the slide 14 synchronously, thereby pushing the magnet in the slide 14 synchronously to the feed end of the curved conveyor 4 on the outside of the mechanism.

[0033] For details, please refer to Figure 6The diagram shows a three-dimensional structural schematic of the control box 2 and the base 1. As can be seen, a controller 17 is embedded in the top panel of the control box 2, integrating a display unit and operation buttons. The base 1 consists of a support frame 18, casters 19, and fixed feet 20. The support frame 18 is a rectangular steel frame structure, its upper end face fixedly connected to the bottom end face of the control box 2 by bolts, providing a stable mounting support base for the control box 2 and its internal functional components. Casters 19 are installed at the four corners of the bottom frame of the support frame 18, facilitating the overall movement and transport of the equipment. Fixed feet 20 are also provided on the bottom frame of the support frame 18 at positions corresponding to each caster 19, and are secured by bolts. The fixed support 20 is connected to the support frame 18 by a grooved fit, and its vertical height can be adjusted by rotating the fixed support 20. When the equipment is moved to the preset work position, the fixed support 20 can be screwed so that its lower end face is lower than the bottom plane of the caster 19, lifting the entire equipment and making the caster 19 detach from the ground. The fixed support 20 is used to achieve horizontal support and positioning of the equipment, avoiding displacement or shaking during the operation of the equipment. At the same time, the level of the equipment can be finely adjusted by adjusting the extension length of each fixed support 20 to ensure the stability of the equipment operation.

[0034] For details, please refer to Figures 7 to 8 , Figure 7 The diagram shown is a three-dimensional structural schematic of the bonding platform, while Figure 8 The diagram shows the use of a multi-axis robotic arm bonding platform. As can be seen from the diagram, the bonding platform includes curved conveyors 4. The conveying channels of the three curved conveyors 4 enclose a storage space. A storage platform 21 is set in the storage space. The upper surface of the storage platform 21 is a horizontal bearing surface used to support the bonding carrier 22 (the bonding carrier 22 in the attached diagram is only for structural display and does not represent its actual size and proportion). The upper surface of the bonding carrier 22 has grooves 23 that correspond one-to-one with the number and arrangement of magnets in the Heilbeck array magnetic component to be formed. These grooves are used to receive magnets of different polarities conveyed from the three curved conveyors 4, providing a precise positioning reference for the bonding of the magnet array. At the end of the conveying channel of each curved conveyor 4, a support frame 24 is fixedly installed. The lower end of the support frame 24 is fixedly connected to the frame of the curved conveyor 4, and the upper end of the support frame 24 extends towards the center of the platform 21. A glue spray head 25 is fixedly installed at the extended end of the support frame 24. The three glue spray heads 25 are interconnected by a rigid glue delivery pipe 26. The glue delivery pipe 26 is provided with a glue inlet 27, which is connected to a glue cylinder 29 through a guide pipe 28. The adhesive stored in the glue cylinder 29 can enter the glue delivery pipe 26 through the guide pipe 28 and the glue inlet 27, and then be distributed to each glue spray head 25. The glue outlet of a single glue spray head 25 is positioned opposite to the edge of the corresponding groove 23 of the bonding carrier 22 on the platform 21.

[0035] This invention primarily addresses the problem of how to batch push multiple magnets onto a conveyor belt. By utilizing the limiting track 10, the chute 14, and multiple sets of push-pull rods 16 in the material feeding temporary storage mechanism, this application enables the synchronous pushing of multiple magnets with the same pole, providing a stable and continuous batch material supply to the curved conveyor 4 and significantly improving magnet feeding efficiency. By limiting the vertical height of the chute 14, only one magnet is output in a single pushing action, effectively preventing the simultaneous removal of stacked magnets from the upper layer, eliminating the faults of multiple magnets getting stuck or misaligned, and ensuring the accuracy and orderliness of the material output process. In conjunction with the Hall magnetic pole detection sensor on the curved conveyor 4, the polarity of the flowing magnets can be identified in real time, and magnets with opposite poles can be rejected, ensuring that the polarity of the magnets entering the bonding station meets the preset requirements, significantly improving the finished product qualification rate of the Heilbeck array magnetic components. By combining multi-axis robotic arms and bonding platforms, the entire process from batch feeding and polarity sorting to array bonding is automated, reducing errors caused by human intervention and improving assembly accuracy and production efficiency.

[0036] In Example 2, during actual continuous production, the bonded Helbeck array magnetic components need to be removed from the platform 21 along with the bonding carrier 22, and then replaced with a new empty bonding carrier 22 for the next round of work. To ensure that the bonded Helbeck array magnetic components can be quickly removed from the platform 21 along the a1 direction and that the new bonding carrier 22 can quickly enter the platform 21 along the a2 direction to complete the workstation switch, while ensuring the positioning accuracy of the bonding carrier 22 during the bonding operation, so that the multi-axis robotic arm can accurately and efficiently pick up and place the bonded Helbeck array magnetic components and the bonding carrier 22, this example further optimizes the design of the bonding carrier 22 on the platform 21.

[0037] For details, please refer to Figures 9 to 10 , Figure 9 The diagram shown is a three-dimensional structural schematic of the optimized adhesive carrier 22. Figure 10 The diagram shows the usage of the optimized bonding carrier 22. As can be seen from the diagram, in this embodiment, an electric telescopic cylinder 30 is embedded in the platform 21. A positioning block 31 is fixed on the output end of the electric telescopic cylinder 30. The bottom of the bonding carrier 22 is provided with a square groove 32 that corresponds to and matches the positioning block 31. The positioning block 31 and the square groove 32 are arranged opposite to each other, and the two can be inserted and matched to form a dedicated positioning structure for the bonding carrier 22.

[0038] In Example 3, during the bonding process between the magnet and the bonding carrier 22, the timing and rate of glue injection directly determine the bonding yield and production efficiency of the Heilbeck array magnetic components. In actual operation, if a single constant rate of glue injection is used, it cannot adapt to the different bonding requirements before and after the magnet enters the groove, and a series of defects are likely to occur: On the one hand, if glue is not injected in advance before the magnet enters the groove 23 of the bonding carrier 22, the magnet will have a rigid collision or dry friction with the groove 23 when it enters the groove, which is very easy to cause the magnet to chip and the plating to be scratched, affecting the magnetic properties and appearance yield of the magnet. Moreover, if glue is injected after the magnet enters the groove, the glue is difficult to evenly cover the bottom bonding surface of the magnet, which is prone to problems such as insufficient glue and weak bonding. Therefore, it is necessary to allow the glue to flow slowly into the groove 23 before the magnet enters the groove 23 of the bonding carrier 22, so as to form a uniform and flat pre-laid glue layer at the bottom of the groove 23. This can not only form a flexible buffer for the magnet entering the groove to avoid damage to the magnet, but also ensure that the bottom surface of the magnet is fully adhered to the adhesive layer after entering the groove, eliminating bonding blind spots. On the other hand, if the adhesive is still injected at a low speed after the magnet enters the groove 23 of the bonding carrier 22, it will not only fail to quickly fill the gap between the outer wall of the magnet and the inner wall of the groove 23, but will also easily leave air bubbles in the gap, significantly reducing the bonding strength and long-term stability of the bonded structure. Furthermore, it will slow down the overall production cycle and cannot meet the needs of automated continuous production. Therefore, after the magnet is positioned in the groove, the adhesive needs to be rapidly and instantly injected into the gap between the magnet and the groove 23 to quickly fill the gap, expel air, ensure that the bonding surface is free of bubbles and loose adhesion, improve the structural strength of the magnetic components and the product yield, and simultaneously meet the fast-paced operation requirements of the automated production line. To solve the problem of accurately controlling the injection rate at different stages before and after the magnet enters the groove during the above-mentioned magnet bonding process, this embodiment further optimizes the design of the bonding platform of the equipment.

[0039] For details, please refer to Figures 11 to 13 ,in Figure 11 The diagram shown is a schematic of the installation structure of the optimized bonding platform. Figure 12 The diagram shown is a three-dimensional structural schematic of the optimized bonding platform. Figure 13The diagram shows a partial structural schematic of the optimized bonding platform. As can be seen, the bonding platform also includes a mounting frame 33. The bottom of the mounting frame 33 is fixedly connected to the outer surface of the rigid adhesive delivery pipe 26, providing a stable mounting reference and radial structural limit for the entire mechanism. The body of the drive motor 34 is fixedly mounted on the inner mounting surface of the mounting frame 33. The output shaft of the drive motor 34 is arranged horizontally, and a half-gear 35 is concentrically fixedly connected to the end of the output shaft. The half-gear 35 has meshing teeth only in a portion of its circumferential area. These meshing teeth can mesh with the vertical teeth of the toothed plate 36 below. The drive motor 34 can drive the half-gear 35 to rotate circumferentially, and through meshing transmission, drive the toothed plate 36 to make vertical linear displacement. The toothed plate 36 is a vertically arranged plate-shaped component, with continuous vertical meshing teeth formed on the side wall facing the half gear 35. The top of the toothed plate 36 is vertically slidably connected to the upper part of the mounting bracket 33 through a sliding lug structure. The mounting bracket 33 limits the horizontal radial displacement of the toothed plate 36, allowing the toothed plate 36 to only reciprocate linearly in the vertical direction. The bottom end face of the toothed plate 36 is fixedly connected to the top end face of the plug 37. The vertical lifting displacement of the toothed plate 36 can synchronously drive the plug 37 to reciprocate along the same stroke in the vertical direction. The plug 37 is slidably inserted into the inside of the glue injection port 27, and the outer wall surface of the plug 37 is slidably sealed to the inner wall surface of the glue injection port 27. A lateral through hole 38 is provided on the side wall of the glue injection port 27, which is the connection point between the glue injection port 27 and the guide pipe 28. A telescopic spring 39 is provided between the plug 37 and the glue injection port 27. The axis of the telescopic spring 39 is coaxially arranged with the sliding axis of the plug 37 and the central axis of the glue injection port 27. When the telescopic spring 39 is in its naturally extended state, the side wall of the plug 37 completely covers and seals the lateral through hole 38 of the side wall of the glue injection port 27, blocking the glue passage between the guide pipe 28, the glue injection port 27, and the glue delivery pipe 26. When the half gear 35 meshes with the toothed plate 36 and drives the toothed plate 36 and the plug 37 to move upward, the plug 37 gradually moves upward and disengages from the lateral through hole 38, opening the glue passage between the guide pipe 28, the glue injection port 27, and the glue delivery pipe 26. When the half gear 35 rotates to the toothless area and disengages from the toothed plate 36, the toothed plate 36 and the plug 37 can slide downward instantaneously along the glue injection port 27 under the restoring force of the telescopic spring 39, resealing the lateral through hole 38.

[0040] Pre-applied adhesive stage (before the magnet enters the tank 23): The drive motor 34 drives the half gear 35 to rotate. The meshing teeth of the half gear 35 mesh with the tooth plate 36 and drive the tooth plate 36 to move upward. Simultaneously, the blocking column 37 slides upward, gradually releasing the blockage of the connection between the guide pipe 28 and the glue injection port 27. The glue in the glue cylinder 29 flows slowly into the glue delivery pipe 26 through the guide pipe 28 and the glue injection port 27, and then slowly flows into the tank 23 of the bonding carrier 22 through the glue spray head 25, forming a pre-applied adhesive layer at the bottom of the tank 23. Instant glue injection stage (after the magnet enters the tank 23): The half gear 35 rotates to the toothless area and disengages from the toothed plate 36. The toothed plate 36 and the plug 37 instantly return to their original positions under the return force of the telescopic spring 39. During the return process, the plug 37 creates an instantaneous impact on the glue in the glue injection port 27, pushing the glue in the glue delivery pipe 26 to be sprayed out at high speed through the glue spray head 25, quickly filling the gap between the magnet and the tank 23, and completing the glue injection.

[0041] Example 4: In actual production operations, there are still technical defects that need to be optimized during batch continuous production. The bonding and molding of the Heilbeck array magnetic components relies on three-directional curved conveyors 4 to accurately and synchronously feed magnets of corresponding polarities into the corresponding slots 23 of the bonding carrier 22. However, in the existing solution, the entry action of the magnets into the slots lacks coordinated control, which easily leads to deviations in the entry timing. This deviation not only causes inconsistent contact and curing times between each magnet and the pre-laid adhesive layer in the slot, resulting in uneven bonding strength, incomplete bonding, and other problems, but may also cause collisions and interference between magnets entering the slots at different positions, causing magnet edge breakage, plating scratches, array polarity misalignment, and other faults, seriously affecting product yield and production cycle stability. To solve the above technical problems, this embodiment further optimizes the magnet entry control structure by setting a blocking mechanism at the end of the conveyor belt of each curved conveyor 4, which is mechanically linked to the bonding platform. When the bonding platform performs a slow pre-applied adhesive application on the empty tank 23, the bonding platform simultaneously activates the blocking mechanism to seal the end of the conveying channel, preventing the magnet from entering the corresponding tank 23. When the bonding platform completes the pre-applied adhesive application and the blocking mechanism simultaneously releases the seal on the magnet, the magnets in the three directions can enter the tank simultaneously without deviation. At the same time, the bonding platform switches to a high-pressure instantaneous adhesive injection mode to complete the adhesive injection into the gap between the magnet and the tank 23. This achieves precise coordination of the entire process of simultaneous magnet entry into the tank and adhesive injection, greatly improving the stability of equipment operation and the product molding yield.

[0042] For details, please refer to Figure 14The diagram shows the installation structure of the blocking mechanism. As can be seen from the diagram, the blocking mechanism includes a connecting frame 40, which is a rigid load-bearing frame with a multi-branch structure. The middle part of the main body of the connecting frame 40 is fixedly connected to the top end face of the toothed plate 36, so that the connecting frame 40 and the toothed plate 36 form a rigid synchronous motion pair. It can move vertically back and forth in the same stroke and sequence as the vertical lifting and lowering movement of the toothed plate 36. The connecting frame 40 extends three equally spaced branches in a ring shape towards the conveying end of the three curved conveyors 4. A stop 5 is fixedly installed at the lower end of each branch. The three stops 5 are arranged one-to-one with the conveying channel ends of the three curved conveyors 4, so that the three stops 5 can achieve completely synchronous vertical lifting and lowering movements with the connecting frame 40 and the toothed plate 36. The stop 5 is fitted into the preset guide structure of the corresponding lifting frame 24 in a vertical sliding fit manner. The lifting frame 24 forms an omnidirectional limit on the horizontal radial displacement of the stop 5, allowing the stop 5 to reciprocate linearly along the vertical direction with the connecting frame 40 and the toothed plate 36.

[0043] When the drive motor 34 of the bonding platform drives the half gear 35 to rotate, and the meshing teeth of the half gear 35 mesh with the toothed plate 36 and drive the toothed plate 36 to gradually move upward, the connecting frame 40 simultaneously drives the three stops 5 to slide upward, gradually releasing the blockage of the conveying channel; when the half gear 35 and the toothed plate 36 are about to disengage, the bonding platform has completed the slow pre-applying of adhesive to the empty trough 23. At this time, the stops 5 have moved up to a high position where the blockage is completely released, and the magnets in the three conveying channels can simultaneously pass through the bottom of the stops 5 and accurately enter the corresponding trough 23 of the bonding carrier 22; When the half gear 35 rotates to the toothless region and completely disengages from the toothed plate 36, the toothed plate 36 instantly resets downward under the reset force of the telescopic spring 39. Simultaneously, the connecting frame 40 drives the three stops 5 to quickly return to their low position limit point. The blocking ends of the stops 5 re-enter the conveying channel, forming a stable blocking limit for the next magnet. At the same time, the bonding platform simultaneously completes instantaneous high-pressure glue injection, completing the glue injection and bonding of the magnet already in the groove and the groove 23.

[0044] Note: As Figure 15The diagram shows a schematic of the connection between the limiting channel and the chute of the present invention. As can be seen from the diagram, in this invention, the magnet to be pushed is assembled in the limiting channel 10 by a sliding fit. The pre-reserved fitting gap between a single magnet and the left and right side walls of the limiting channel 10 is insufficient to cause the magnet to deflect during vertical dropping. The inner width of the limiting channel 10 is completely consistent with the width of the chute 14, and the inner channel of the limiting channel 10 and the chute 14 are completely aligned vertically. The magnet falls vertically into the chute 14 via the limiting channel 10. During the process, no horizontal deviation will occur, thus preventing the magnet from deflecting within the chute 14. At the same time, the vertical height inside the chute 14 is greater than the vertical height of a single magnet to be pushed, but less than the total vertical height of two magnets to be pushed. This ensures that only one magnet can be accommodated in a single chute 14 at the same time. When the push rod 16 pushes the magnet out of the chute 14, it will not bring out the magnets stacked above the limit channel 10, ensuring that only one magnet can be output in a single pushing action, thus achieving orderly and precise magnet discharge.
