Description

Technical Field

[0001] The present invention relates to the technical field of magnet assembly, and in particular discloses a rotary NdFeB magnet automatic assembly machine and an assembly method. Background Art

[0002] In the field of the assembly of NdFeB magnets and cover plates, traditional production methods mostly rely on manual or semi-automatic operations, which have significant limitations. On the one hand, manual assembly requires frequent material handling and process connection, and is easily affected by the operation proficiency, resulting in problems such as deviation in the fitting position and uneven glue coating, with poor product consistency and high rejection rate. On the other hand, existing semi-automatic equipment often disperses each process in independent workstations, and the connection between processes takes time and occupies a large space, making it difficult to meet the requirements of high-efficiency production. In addition, the traditional equipment has insufficient versatility. When facing magnets or cover plates of different specifications, it often requires large-scale replacement of tooling or even equipment modification, increasing the enterprise production cost and downtime. At the same time, there is a lack of real-time quality monitoring and data traceability mechanism, and it is difficult to quickly locate the root cause when quality anomalies occur, affecting process optimization and product reliability. With the increasing requirements for component stability (such as vibration resistance and shear resistance) in fields such as automotive motors and industrial sensors, the traditional assembly method can no longer adapt to the production trend of high precision and large scale, and there is an urgent need for an automated and flexible integrated solution. Summary of the Invention

[0006] Further, the cover plate feeding mechanism includes a cover plate guiding component, a cover plate supporting component slidably arranged on the cover plate guiding component, and a linear driving component for driving the cover plate supporting component to reciprocate on the cover plate guiding component; a cover plate transferring component is arranged between the cover plate supporting component and the carrying station, and the cover plate transferring component cooperates with the linear driving component to transfer the cover plates on the cover plate supporting component to the carrying station one by one.

[0007] Further, the cover plate feeding mechanism further includes a rotating turntable base body and a rotating driving component for driving the turntable base body to rotate. The number of the cover plate guiding components and the cover plate supporting components is set to be multiple, and the multiple cover plate guiding components and the multiple cover plate supporting components are all distributed along the circumferential direction of the turntable base body; the rotating driving component drives the turntable base body to rotate intermittently through a second cam divider, so that the cover plate supporting components on each cover plate guiding component cooperate with the material transferring component in turn to complete the continuous feeding of the cover plates.

[0008] Further, the dispensing mechanism includes a moving platform, a drying aid coating unit and an adhesive coating unit arranged on the moving platform, and the moving platform realizes reciprocating movement through a dispensing driving component.

[0009] Further, the pressing mechanism has a pressing member reciprocatingly arranged on the machine frame and a pressing driver for driving the pressing member to reciprocate, and the pressing head is located above the carrying station.

[0010] Further, the rotary NdFeB magnet automatic assembly machine further includes a turntable support component, and the turntable support component has a plurality of support columns arranged in a row along the direction of the rotation axis of the turntable component, and rolling members are movably arranged on the support columns to roll and abut against the turntable component.

[0011] Further, the carrying station has a carrying plate arranged on the turntable component. The carrying plate is provided with accommodation grooves for accommodating magnets and / or cover plates. The accommodation grooves are provided with slidable limit blocks. The limit blocks are connected to the turntable component via telescopic springs, and the limit blocks are provided with stop protrusions, and the stop protrusions abut against the turntable component via the elastic force of the telescopic springs.

[0012] A method for assembling a rotary NdFeB magnet, comprising the following steps:

[0013] S1: The rotary drive source drives the rotary table assembly to rotate intermittently through the first cam divider, so that a single loading station rotates to the loading position of the magnet feeding mechanism; the feeding drive assembly pushes the magnets at the front end of the queue in the magnet guiding assembly to the loading position one by one, the picking and executing assembly grabs the magnets and transfers them to the accommodating groove of the loading station, and after preliminary positioning through the cooperation of the limiting block and the spring, the blocking protrusion of the limiting block abuts against the rotary table assembly to perform secondary calibration on the position of the magnets;

[0014] S2: The rotary table assembly rotates, so that the loading station carrying the magnet rotates below the dispensing mechanism; the dispensing drive assembly of the dispensing mechanism drives and controls the drying agent coating unit and the adhesive coating unit through the moving platform to uniformly coat the drying agent and the adhesive on the preset bonding surface of the magnet;

[0015] S3: The rotary table assembly rotates to make the loading station carrying the glued magnet rotate to the discharge end of the cover plate feeding mechanism; the rotary drive assembly of the cover plate feeding mechanism drives the rotary table base to index through the second cam divider, the linear drive assembly drives the cover plate support assembly to reciprocate, and the cover plate transfer assembly cooperates with the linear drive assembly to transfer the cover plates to the loading station one by one, align and stack them above the dispensed magnets to complete the preliminary bonding of the two.

[0016] Further, it further comprises the following steps:

[0017] S4: The rotary table assembly indexes the loading station to the lower part of the pressing mechanism in sequence, and the pressing driver drives the pressing part to move downward to apply a preset pressure to the preliminarily bonded magnet and cover plate, so that the glue fully infiltrates the bonding surface and cures to complete the double fixation of mechanical and adhesive bonding;

[0018] S5: The rotary table assembly rotates the pressed and cured magnet and cover plate to the position of the discharging mechanism, and the discharging mechanism takes out the finished product from the loading station and transfers it to the required position by means of vacuum adsorption or clamping jaw grasping. At the same time, the rotary table assembly continues to rotate to enter the next round of cyclic process.

Detailed implementation manners

[0035] To further elaborate on the technical means and effects adopted by the present invention to achieve the intended invention purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation manners, structures, features, and their effects of the present invention as follows.

[0036] Please refer to Figures 1 to 6 As shown, a rotary NdFeB magnet automatic assembly machine of the present invention includes a frame 1, a turntable assembly 2 provided on the frame 1, a rotary drive source 3 for driving the rotation of the turntable assembly 2, a plurality of loading stations 4 provided on the turntable assembly 2 and distributed in the circumferential direction of the rotation axis of the turntable assembly 2, a magnet feeding mechanism 5 for feeding magnets onto the loading stations 4, a dispensing mechanism 6 for coating glue on a preset bonding surface of the magnets, a cover feeding mechanism 7 for feeding covers onto the preset bonding surface of the magnets after coating glue and initially bonding them, a pressing mechanism 8 for pressing and fixing the initially bonded covers and magnets, and a discharging mechanism 9 for transferring the covers and magnets pressed and fixed by the pressing mechanism 8 to the next process; a first cam divider 31 is provided between the rotary drive source 3 and the turntable assembly 2, and the first cam divider 31 is used to regulate the intermittent rotation of the turntable assembly 2 to cooperate with the coordinated work between the plurality of loading stations 4 and each mechanism, so as to realize the automatic positioning, glue coating, pressing, and discharging processes of the magnets and covers.

[0037] In actual use, through the circumferential station layout of the turntable assembly 2, the processes of magnet loading, glue dispensing, cover plate lamination, pressing and discharging are integrated into the same equipment, realizing the full process automation of "positioning → gluing → assembly → pressing → discharging", avoiding manual intervention and time-consuming material handling between processes, and significantly shortening the single product production cycle. The first cam divider 31 controls the intermittent rotation of the turntable, so that each bearing station 4 is precisely docked with each mechanism (loading, glue dispensing, pressing, etc.) in turn according to the set rhythm, ensuring that each process is carried out synchronously and orderly, avoiding conflicts in mechanism movements, and improving the operating efficiency and stability of the equipment.

[0038] The precise indexing function of the first cam divider 31 (such as the cam first cam divider 31) ensures that the turntable rotation angle error is extremely small (usually within ±15 seconds), and cooperates with the precise positioning of each mechanism (such as the mechanical gripper of the feeding mechanism and the coordinate calibration of the dispensing head) to ensure the uniformity of the fitting position of the magnet and the cover plate, the glue coating area and the pressing pressure, avoid problems such as position deviation or glue overflow in manual assembly, and improve the assembly accuracy and consistency of the product. The flow rate, pressure of the dispensing mechanism 6 and the pressure, time and other parameters of the pressing mechanism 8 can be accurately set through the control system to avoid subjective differences in manual operation, ensure that the glue coating amount and pressing strength of each product meet the process standards, and reduce the defective rate. The equipment can integrate sensors (such as pressure sensors, visual inspection modules) to monitor key parameters such as dispensing amount, fitting position, pressing pressure, etc. in real time, and cooperate with the control system to record production data, which is convenient for subsequent quality traceability and process optimization, and improves the transparency and controllability of the production process.

[0039] Furthermore, the magnet feeding mechanism 5 includes a magnet guide component 51, an elastic drive component 52, a feeding drive component 53 and a material picking execution component 54. The magnet guide component 51 is used to store magnets and guide the movement of magnets. One end of the elastic drive component 52 is connected to the magnet guide component 51, and the other end pushes the magnet through a slidable pushing block 55, so that the magnet forms a queue to be fed in the magnet guide component 51. The feeding drive component 53 is used to push the magnets at the front end of the feeding queue to the feeding position one by one. The elastic drive component 52 applies a continuous elastic force to the pushing block 55, so that the magnets at the rear end of the feeding queue automatically advance toward the front end. The material picking execution component 54 is used to move the magnets at the feeding position to the carrying station 4.

[0040] During actual use, the magnet guiding component 51 can store magnets and guide their movement. The elastic driving component 52 pushes the magnet through the pushing block 55, enabling the magnets to form a queue for feeding in the guiding component, ensuring the orderly feeding of magnets. This avoids situations such as chaos and accumulation of magnets during the feeding process, laying a foundation for subsequent accurate feeding one by one. The elastic driving component 52 applies a continuous elastic force to the pushing block 55, causing the magnets at the rear end of the feeding queue to automatically advance to the front end. This feature realizes the automatic replenishment of magnets, eliminating the need for frequent manual intervention and manual adjustment of magnet positions, saving labor and time costs, and improving the continuity of feeding and production efficiency.

[0041] The feeding driving component 53 pushes the magnets at the front end of the feeding queue to the feeding position one by one, capable of precisely controlling the quantity of each feeding, ensuring that only one magnet is pushed to the feeding position each time, avoiding problems such as overfeeding or missing feeding, improving the accuracy and reliability of feeding, and thus ensuring the smooth progress of subsequent assembly processes. The material taking and executing component 54 is used to transfer the magnets at the feeding position to the carrying station 4. This component can flexibly achieve the transfer action of the magnets according to the overall layout and operation requirements of the equipment. It can accurately place the magnets at the designated position of the carrying station 4 and cooperate with the turntable component 2 and other mechanisms to ensure the positioning accuracy of the magnets during the assembly process. The design of this feeding mechanism can adapt to magnets of different specifications and shapes (within a certain range). By appropriately adjusting components such as the magnet guiding component 51 and the pushing block 55, it can meet the feeding requirements of different products, having strong versatility and adaptability, and reducing the equipment transformation cost when the enterprise changes product models.

[0042] Furthermore, the cover plate feeding mechanism 7 further includes a rotating turntable base 75 and a rotating driving component 76 for driving the turntable base 75 to rotate. The number of the cover plate guiding components 71 and the cover plate supporting components 72 is set to be multiple, and the multiple cover plate guiding components 71 and the multiple cover plate supporting components 72 are all distributed circumferentially along the turntable base 75. The rotating driving component 76 drives the turntable base 75 to rotate intermittently through the second cam divider 77, enabling the cover plate supporting components 72 on each cover plate guiding component 71 to cooperate with the material transfer component in sequence to complete the continuous feeding of the cover plates.

[0043] During actual use, the cover plate guiding assembly 71 can store and guide the movement of the cover plate, keeping the cover plates in an orderly state during the conveying process, avoiding chaos, stacking, etc. between the cover plates, ensuring the stability and reliability of feeding, and preparing for accurately placing the cover plates onto the loading station 4 subsequently. The slidable cover plate supporting assembly 72 cooperates with the linear driving assembly 73 to enable the reciprocating movement of the cover plate on the guiding assembly. This design allows the cover plate to be accurately conveyed to the designated position, facilitating the grasping and transferring operations of the cover plate transferring assembly 74. Meanwhile, the use of the linear driving assembly 73 can precisely control the movement of the cover plate supporting assembly 72, improving the accuracy and efficiency of cover plate conveying.

[0044] The cover plate transferring assembly 74 cooperates with the linear driving assembly 73 to transfer the cover plates on the cover plate supporting assembly 72 to the loading station 4 one by one, capable of precisely controlling the quantity of each feeding, ensuring that only one cover plate is placed onto the loading station 4 each time, avoiding problems such as overfeeding or missing feeding, improving the accuracy of feeding, and guaranteeing the accuracy and quality of subsequent magnet and cover plate assembly. By appropriately adjusting components such as the cover plate guiding assembly 71 and the cover plate supporting assembly 72, this feeding mechanism can adapt to cover plates of different specifications and shapes (within a certain range), having strong versatility and adaptability. When an enterprise changes the product model, there is no need to conduct large-scale modification of the equipment. Only minor adjustments to relevant components are required to meet the new feeding requirements, reducing the equipment modification cost. This feeding mechanism realizes the automated operation of the cover plate from storage, conveying to transferring to the loading station 4, reducing manual intervention, lowering the labor cost, and improving the production efficiency. At the same time, the automated operation also reduces the influence of human factors on product quality, making the product quality more stable and reliable.

[0045] Furthermore, the cover plate feeding mechanism 7 further includes a rotating turntable base 75 and a rotary driving assembly 76 for driving the rotation of the turntable base 75. The numbers of the cover plate guiding assembly 71 and the cover plate supporting assembly 72 are both set to be multiple, and the multiple cover plate guiding assemblies 71 and the multiple cover plate supporting assemblies 72 are all circumferentially distributed along the turntable base 75. The rotary driving assembly 76 drives the turntable base 75 to perform indexing rotation through a second cam divider 77, enabling the cover plate supporting assemblies 72 on each cover plate guiding assembly 71 to cooperate with the material transferring assembly in sequence to complete the continuous feeding of the cover plates.

[0046] In actual use, multiple cover plate guiding components 71 and cover plate supporting components 72 are provided and distributed circumferentially along the turntable base 75. The turntable base 75 is driven to rotate by indexing through the rotation driving component 76, so that each cover plate supporting component 72 can cooperate with the material transfer component in turn for cover plate loading. This design realizes the continuous loading of the cover plate. Compared with the single-component loading, the loading speed is greatly improved, and further the production efficiency of the entire assembly machine is enhanced, meeting the requirements of large-scale production. The rotation driving component 76 drives the turntable base 75 to rotate by indexing through the second cam divider 77. The second cam divider 77 can provide accurate indexing motion, ensuring that each cover plate guiding component 71 and cover plate supporting component 72 can accurately reach the predetermined position during the rotation process, so that the material transfer component can accurately grasp and transfer the cover plate, improving the accuracy and reliability of the loading and ensuring the accuracy of the subsequent assembly of the cover plate and the magnet.

[0047] The application of the second cam divider 77 makes the rotation of the turntable base 75 stable and reliable, reducing the impact and vibration during the movement process. Multiple loading units work in sequence. Even if a certain unit has a short-term failure or abnormality, other units can still continue to operate, without causing the interruption of the entire loading process, improving the stability and reliability of the equipment operation and reducing the frequency of equipment shutdown for maintenance. Due to the adoption of the structure of multiple loading units distributed circumferentially, when it is necessary to improve the production efficiency or adapt to different production requirements, it is relatively convenient to increase or decrease the number of cover plate guiding components 71 and cover plate supporting components 72, flexibly expand or adjust the equipment, with good scalability and adaptability, and reducing the cost of equipment replacement due to changes in production scale for enterprises.

[0048] Furthermore, the dispensing mechanism 6 includes a moving platform 61, a drying aid coating unit 63 and an adhesive coating unit 64 arranged on the moving platform 61. The moving platform 61 realizes reciprocating motion through the dispensing driving component 62.

[0049] In actual use, the dispensing mechanism 6 integrates the drying aid coating unit 63 and the adhesive coating unit 64 on the moving platform 61, realizing the coating functions of two different liquids (drying aid and adhesive) in one mechanism. This reduces the number of independent mechanisms in the equipment, makes the structure of the entire assembly machine more compact, saves equipment space, and at the same time reduces the complexity and cost of the equipment. The moving platform 61 realizes reciprocating motion through the dispensing driving component 62, enabling the drying aid coating unit 63 and the adhesive coating unit 64 to flexibly move and operate at the positions where coating is required (such as the preset bonding surface of the magnet). It is possible to accurately control the coating units to perform coating at different positions and different areas according to different production requirements and product specifications, improving the flexibility and adaptability of the dispensing operation.

[0050] The dispensing drive assembly 62 can accurately control the movement of the dispensing mechanism 6, thereby ensuring the positional accuracy of the drying aid and the adhesive during the coating process and the uniformity of the coating amount. It helps to improve the bonding effect between the magnet and the cover plate, ensures the stability and consistency of the product quality, and reduces product defects caused by uneven coating. Since two coating functions are integrated in one mechanism and the coating operation can be quickly switched through the reciprocating motion of the moving platform 61, there is no need to transfer materials or adjust equipment between different independent mechanisms, saving production time and improving production efficiency. It can complete the glue coating process of the magnet more quickly, thereby accelerating the entire assembly process.

[0051] Further, the pressing mechanism 8 has a pressing member 81 reciprocatingly arranged on the frame 1 and a pressing driver 82 for driving the pressing member 81 to reciprocate, and the pressing head is located above the loading station 4.

[0052] During actual use, the pressing member 81 is reciprocatingly arranged on the frame 1 and is located above the loading station 4. After the magnet and the cover plate are initially fitted, it can accurately reach the predetermined position for the pressing action. The pressing driver 82 drives the pressing member 81 to move, which can precisely control the pressing force and stroke, ensuring a tight fit between the magnet and the cover plate, improving the quality and stability of product assembly, and reducing problems such as product looseness caused by insufficient pressing. By using the pressing driver 82 to achieve the reciprocating motion of the pressing member 81, the pressing process can be automated without manual operation of the pressing action. This further improves the automation level of the entire assembly machine, reduces the labor input, reduces the errors and labor intensity of manual operation, improves the production efficiency, and is conducive to realizing large-scale automated production.

[0053] Since the pressing driver 82 can adjust the motion parameters of the pressing member 81 (such as pressure magnitude, motion speed, stroke, etc.), the pressing mechanism 8 can adapt to the pressing requirements of magnets and cover plates of different specifications and types. For different combinations of material thickness and hardness, the best pressing effect can be achieved by adjusting the pressing parameters, which has strong versatility and adaptability, and reduces the cost for enterprises to replace equipment due to product model changes.

[0054] Further, the rotary NdFeB magnet automatic assembly machine further includes a turntable support assembly 11, and the turntable support assembly 11 has a plurality of support columns 12 arranged in a direction around the rotation axis of the turntable assembly 2, and rolling members 13 are movably provided on the support columns 12 to roll and abut against the turntable assembly 2.

[0055] In actual use, multiple support columns 12 are arranged around the rotation axis direction of the turntable assembly 2, providing multiple support points for the turntable assembly 2 and evenly dispersing the weight and load borne by the turntable assembly 2 during rotation. This effectively avoids unstable situations such as shaking and tilting of the turntable assembly 2 due to uneven force, ensures the smooth rotation of the turntable assembly 2, and further ensures the position accuracy of the materials (magnets and cover plates) on each loading station 4 during the processing, improving the assembly quality of the product. The rolling elements 13 movably arranged on the support columns 12 are in rolling contact with the turntable assembly 2. Compared with sliding friction, the friction coefficient of rolling friction is smaller. This greatly reduces the frictional resistance between the turntable assembly 2 and the support columns 12 during rotation, makes the rotation of the turntable assembly 2 smoother, reduces energy consumption, and improves the operating efficiency of the equipment. At the same time, the smaller frictional resistance also helps to extend the service life of the turntable assembly 2 and the support columns 12 and reduce the maintenance cost of the equipment.

[0056] Due to the presence of the rolling elements 13, the frictional resistance is reduced, enabling the turntable assembly 2 to rotate at high speed more easily. During the production process, the rotation speed of the turntable assembly 2 can be increased according to actual needs, thereby accelerating the production rhythm, improving production efficiency, and meeting the requirements of large-scale production. Moreover, the stable support and small friction also ensure the stability and reliability of the turntable assembly 2 during high-speed rotation. The design of this turntable support assembly 11 does not depend on the specific size or shape of the turntable assembly 2. Within a certain range, for turntable assemblies 2 of different specifications, only parameters such as the position and quantity of the support columns 12 need to be appropriately adjusted to achieve a good support effect. Therefore, this turntable support assembly 11 has strong versatility and can adapt to various types of rotary NdFeB magnet automatic assembly machines, reducing the cost of equipment design and manufacturing.

[0057] Furthermore, the loading station 4 has a loading plate 41 provided on the turntable assembly 2. The loading plate 41 is provided with a receiving groove 42 for receiving magnets and / or cover plates. A slidable limiting block 43 is provided in the receiving groove 42. The limiting block 43 is connected to the turntable assembly 2 via a telescopic spring 44, and the limiting block 43 is provided with a stop protrusion 45. The stop protrusion 45 abuts against the turntable assembly 2 by the elastic force of the telescopic spring 44.

[0058] In actual use, the receiving groove 42 on the bearing plate 41 is used to accommodate magnets and / or cover plates, which can preliminarily position the material and ensure that the material is accurately placed on the bearing station 4. At the same time, the slidable limit block 43 cooperates with the receiving groove 42 to further limit the material to prevent the material from being displaced or shaken during the rotation of the turntable assembly 2, thereby ensuring the position accuracy of the material in each process (such as dispensing, pressing, etc.), thereby improving the assembly quality of the product. The presence of the telescopic spring 44 not only enables the limit block 43 to flexibly adjust its position, but also plays a buffering role when the turntable assembly 2 rotates or is impacted by external forces. When the turntable assembly 2 suddenly accelerates, decelerates or is vibrated, the telescopic spring 44 can absorb part of the impact force, reduce the direct impact on the material, prevent the material from being damaged due to excessive force, protect the integrity of the material, and improve the yield rate of the product.

[0059] The limit block 43 is connected to the turntable assembly 2 through a telescopic spring 44. This elastic connection allows the limit block 43 to be adjusted to a certain extent according to the size of the material. For magnets and cover plates of different specifications, the limit block 43 can automatically adapt to the shape of the material under the action of the telescopic spring 44 to provide a suitable limiting effect. There is no need to frequently replace the structural components of the load-bearing station 4, which enhances the adaptability and versatility of the equipment to different products and reduces the cost of adjusting the equipment for enterprises due to changes in product models. The stop protrusion 45 on the limit block 43 contacts the turntable assembly 2 through the elastic force of the telescopic spring 44, so that the limit block 43 can maintain a stable position during the process of limiting the material. Even if the equipment is disturbed by a certain external force during operation, the contact between the stop protrusion 45 and the turntable assembly 2 can prevent the limit block 43 from sliding at will, ensuring the reliability of the limiting function and ensuring the stable placement of the material on the load-bearing station 4.

[0060] Furthermore, a turntable NdFeB magnet assembly method comprises the following steps:

[0061] S1: The rotary drive source 3 drives the turntable assembly 2 to rotate intermittently through the first cam divider 31, so that the single load-bearing station 4 rotates to the loading position of the magnet loading mechanism 5; the loading drive assembly 53 pushes the magnets at the front end of the queue in the magnet guide assembly 51 to the loading position one by one, and the material taking execution assembly 54 grabs the magnets and transfers them to the receiving groove 42 of the load-bearing station 4. After the initial positioning by the cooperation of the limit block 43 and the spring, the stop protrusion 45 of the limit block 43 contacts the turntable assembly 2, and the magnet position is calibrated for the second time;

[0062] S2: The turntable assembly 2 rotates to rotate the bearing station 4 bearing the magnet to the bottom of the glue dispensing mechanism 6; the glue dispensing driving assembly 62 of the glue dispensing mechanism 6 drives and controls the drying aid coating unit 63 and the adhesive coating unit 64 through the mobile platform 61 to evenly coat the drying aid and the adhesive on the preset bonding surface of the magnet;

[0063] S3: The turntable assembly 2 rotates to move the loading station 4 carrying the glued magnets to the discharge end of the cover feeding mechanism 7; the rotary drive assembly 76 of the cover feeding mechanism 7 drives the turntable base 75 to index through the second cam divider 77, the linear drive assembly 73 drives the cover support assembly 72 to reciprocate, and the cover transfer assembly 74 cooperates with the linear drive assembly 73 to transfer the covers to the loading station 4 one by one, accurately align and stack them above the magnet with glue applied, completing the preliminary fitting of the two.

[0064] In actual use, the dual application of the first cam divider 31 and the second cam divider 77 ensures the accurate indexing of the turntable assembly 2 and the cover feeding mechanism 7. The loading station 4 sequentially switches to stations such as magnet feeding, glue dispensing, and cover feeding according to a preset trajectory, and each process is seamlessly connected, avoiding idling or waiting time. Compared with traditional intermittent assembly, the production cycle is shortened, and the production capacity per unit time is significantly improved. When feeding the magnets, the limit block 43 and the spring form a flexible positioning system: the receiving groove 42 completes the initial positioning, the spring pushes the limit block 43 to adaptively fit the contour of the magnet, and the stop protrusion 45 abuts against the turntable assembly 2 to achieve secondary calibration, with the positioning error controlled within ±0.05 mm. This mechanism is compatible with magnets of various sizes, and only the spring pre-tightening force needs to be slightly adjusted during production changeover, reducing the cost of tooling replacement.

[0065] The drying aid and adhesive dual units of the glue dispensing mechanism 6 operate synchronously, and the moving platform 61 accurately controls the coating path. By presetting parameters through the PLC, the coating speed and flow rate can be adjusted according to the characteristics of different glue liquids. Compared with manual glue coating, the glue consumption is reduced and the coating uniformity is improved, effectively reducing the defect rates such as glue overflow and lack of glue. The cover feeding mechanism 7 adopts a "turntable + linear drive" composite mode, and multiple groups of guiding components distributed circumferentially can perform parallel feeding. The linear drive assembly 73 cooperates with the transfer mechanism to achieve "pick-up - translation - accurate alignment" of the cover. By replacing the appropriate fixtures, it can be compatible with various cover specifications such as square and round, improving the equipment reuse rate. The full process from magnet feeding to cover fitting is automated, reducing the manual operation links. The sensors monitor the material status of each station in real time, and when an abnormality occurs, it automatically triggers an alarm and pauses the turntable, avoiding material waste and equipment damage. The standardized operation process shortens the training cycle for new employees, significantly reducing the labor cost and the operation error rate.

[0066] Further, the following steps are also included:

[0067] S4: The turntable assembly 2 indexes the loading station 4 to the lower part of the pressing mechanism 8 in sequence, and the pressing driver 82 drives the pressing member 81 to move downward, applying a preset pressure to the preliminarily fitted magnet and cover, so that the glue fully infiltrates the fitting surface and cures, completing the double fixation of mechanical and adhesive bonding;

[0068] S5: The turntable assembly 2 rotates the magnet and cover plate after press-fitting and curing to the position of the discharging mechanism 9. The discharging mechanism 9 takes out the finished product from the loading station 4 and transfers it to the required position by means of vacuum adsorption or gripper grasping. At the same time, the turntable assembly 2 continues to rotate and enters the next round of cyclic processes.

[0069] In actual use, the press-fitting mechanism 8 realizes the synergistic effect of full infiltration of glue and mechanical fastening through preset pressure parameters (such as adjustable from 0.5 - 2 MPa). After testing, the shear strength of the finished product is increased by 40%, and the vibration resistance performance reaches the IP65 standard, effectively solving the problem of easy glue detachment in traditional single gluing, and is especially suitable for high-reliability demand scenarios such as automotive motors and industrial sensors. The dual-mode discharging mechanism 9 of vacuum adsorption and gripper grasping can be flexibly switched according to the product weight and surface characteristics. The adaptation cycle can reach 8 - 15 seconds per piece, supports docking with an automated sorting line or packaging equipment, and realizes the accuracy calibration of the discharging position within ±1 mm through PLC control, reducing the secondary positioning cost of the subsequent process.

[0070] The automatic reset function and process synchronization trigger mechanism of the turntable assembly 2 control the cycle error within ±0.3 seconds. Combined with the real-time monitoring of the discharging station by the sensor (automatic replenishment in case of material shortage), it can achieve non-stop production for 7×24 hours, and the overall equipment efficiency (OEE) is increased to more than 85%, reducing the downtime loss caused by manual intervention. Key parameters such as press-fitting pressure and discharging time are automatically recorded in the MES system to form a unique QR code traceability file for the product. When quality anomalies occur, the assembly parameters of the corresponding batch can be quickly located, and the traceability time of defective products is shortened from the traditional 2 hours to 15 minutes, facilitating quality control and process optimization. The modular design of the discharging mechanism 9 (quick-change interface for the adsorption head / gripper) shortens the single-station maintenance time to 10 minutes. The zeroing and calibration program of the turntable assembly 2 is integrated into the HMI interface, and the operator can complete the equipment initialization through one-key operation, with an efficiency improvement of 70% compared to traditional manual calibration, reducing the proportion of non-production working hours.

[0071] In this embodiment, the magnet guiding component 51 is a linear guiding member 511 provided on the frame 1. The linear guiding member 511 is provided with a guiding plate 512 and a guiding groove 513. The guiding groove 513 is recessed from the surface of the linear guiding member 511. The guiding plate 512 and the guiding groove 513 are both arranged along the length direction of the linear guiding member 511, and the guiding plate 512 at least partially covers the guiding groove 513 to limit the magnet located in the guiding groove 513.

[0072] In actual use, the linear guide 511 provides an accurate guiding path for the movement of the magnet. The guide plate 512 and the guide groove 513 are arranged along the length direction of the linear guide 511, enabling the magnet to move along a specific trajectory, avoiding deflection or shaking during the movement of the magnet, ensuring the linearity and stability of the magnet movement, and being beneficial to improving the accuracy and reliability of the equipment operation. The guide plate 512 at least partially covers the guide groove 513, playing a limiting role on the magnet located in the guide groove 513. This can prevent the magnet from disengaging from the guide groove 513, ensure the stable movement of the magnet in the guide groove 513, enhance the structural stability and safety of the magnet guiding assembly 51, and avoid equipment failures or damages caused by the magnet disengaging from the guide groove 513.

[0073] This design of the linear guide 511 can be applied to a variety of different equipment and scenarios, and can be used wherever guiding and limiting of the magnet are required, having strong versatility and adaptability. Since the magnet can move stably along an accurate path, the adjustment and calibration work required due to magnet deflection or shaking are reduced, thereby improving the working efficiency of the equipment and ensuring the continuity of production or operation. Through the effective guiding and limiting of the magnet, the operation of the entire system becomes more stable, reducing the vibration and noise caused by the instability of the magnet, and improving the quality of the equipment working environment.

[0074] In this embodiment, the elastic drive assembly 52 has a runner 521 rotatably arranged on the linear guide 511. The push block 55 is slidably connected to the guide plate 512, and a clockwork spring 522 is provided between the runner 521 and the push block 55.

[0075] In actual use, the clockwork spring 522 can store elastic potential energy when the runner 521 rotates and release it when needed, providing a continuous and stable elastic driving force to the push block 55. This enables the push block 55 to slide along the guide plate 512 and can adjust the force according to the specific working conditions during the sliding process to adapt to different working requirements. During the movement of the push block 55, the clockwork spring 522 can play a role in buffering and shock absorption. When the push block 55 encounters resistance or is impacted by an external force, the clockwork spring 522 can absorb and disperse the energy, reducing the impact of the impact force on the entire assembly, protecting the equipment components, and extending their service life.

[0076] By adjusting the pre-tightening force of the clockwork spring 522 or replacing the clockwork spring 522 with a different elastic coefficient, the driving force of the pushing block 55 can be conveniently adjusted. This enables the elastic driving assembly 52 to adapt to different working loads and operating conditions, improving the flexibility and adaptability of the device. The rotation of the runner 521 in cooperation with the clockwork spring 522 can make the sliding of the pushing block 55 smoother. The rotation of the runner 521 can evenly convert the elastic potential energy of the clockwork spring 522 into the kinetic energy of the pushing block 55, reducing the jamming and jitter phenomena during the movement of the pushing block 55 and improving the operating accuracy and stability of the device.

[0077] In this embodiment, the cover plate guiding assembly 71 includes a plurality of guide rods 711, the cover plate supporting assembly 72 is slidably connected to the plurality of guide rods 711, and the plurality of guide rods 711 and the cover plate supporting assembly 72 together form a bin for accommodating the cover plate.

[0078] During actual use, the arrangement of the plurality of guide rods 711 provides precise guidance for the cover plate supporting assembly 72, enabling the cover plate supporting assembly 72 to slide smoothly along the guide rods 711. This ensures that the cover plate does not shift or shake during movement, ensuring that the cover plate can accurately reach the predetermined position, which is beneficial to improving the operating accuracy of the device. The plurality of guide rods 711 and the cover plate supporting assembly 72 together form a bin, and this structure enhances the overall stability of the bin. The guide rods 711 can evenly bear the weight of the cover plate and other external forces, preventing the bin from deforming or being damaged due to uneven stress, and extending the service life of the device. The precise guidance and stable structure enable the cover plate to be quickly and accurately transported to the designated position, reducing the adjustment and waiting time caused by inaccurate cover plate positioning, improving the efficiency of cover plate installation or use on the production line, and thus enhancing the efficiency of the entire production process.

[0079] The formation of the bin facilitates the storage of the cover plate, can accommodate a certain number of cover plates, and reduces the storage space of the cover plates. At the same time, since the cover plate supporting assembly 72 is slidably connected to the guide rods 711, when taking the cover plate, the cover plate supporting assembly 72 can be easily slid to a suitable position, facilitating the operator to take the cover plate and improving the work efficiency. By increasing or decreasing the number of guide rods 711 and adjusting the spacing between the guide rods 711, the size and capacity of the bin can be conveniently adjusted to adapt to the storage requirements of cover plates of different sizes and quantities. This scalability makes the structure highly versatile and adaptable, capable of meeting the requirements of different production scales and product types.

[0080] In this embodiment, a connecting piece 712 is provided at the guiding end of the plurality of cover plate guiding assemblies 71, and the connecting piece 712 is connected to the plurality of guide rods 711 of the plurality of cover plate guiding assemblies 71 to enhance the stability between the guide rods 711.

[0081] In actual use, the connector 712 connects the multiple guide rods 711 of the multiple cover plate guide assemblies 71, so that the originally relatively independent guide rods 711 form a more stable overall structure. When bearing the weight of the cover plate and other external forces, the connector 712 can effectively disperse the stress, prevent the single guide rod 711 from being deformed, bent or damaged due to excessive force, and greatly improve the stability and reliability of the entire guide assembly system. When the stability between the guide rods 711 is enhanced, the straightness and relative position accuracy of the guide rods 711 can be better maintained in the process of guiding the cover plate support assembly 72 to slide. This helps to ensure that the cover plate always moves along the correct path during movement, reduces the cover plate positioning error caused by the shaking or deviation of the guide rods 711, thereby improving the guidance accuracy of the equipment to the cover plate and ensuring the smooth progress of subsequent work.

[0082] During the operation of the equipment, especially in some working conditions with large vibration or frequent start and stop, the guide rod 711 may have a slight displacement. The existence of the connecting piece 712 can limit the displacement of the guide rod 711, so that the guide rod 711 remains in a fixed position, maintains the normal working state of the guide assembly, and reduces the risk of equipment failure caused by the displacement of the guide rod 711. The stable guide rod 711 structure helps to improve the overall performance of the equipment, making the equipment more stable and reliable during operation. For equipment that requires high-precision operation, this improvement in stability can significantly improve production efficiency and product quality.

[0083] In this embodiment, an elastic buffer pad is provided at the bottom of the pressing member 81. The elastic buffer pad is made of rubber or silicone to avoid damage to the magnet and the cover during the pressing process.

[0084] In actual use, during the lamination process, the elastic buffer pad can effectively absorb and disperse the impact force generated during lamination. Rubber or silicone has good elastic deformation ability. When the lamination piece 81 contacts the magnet and the cover plate, the buffer pad will undergo elastic deformation to reduce the force of lamination, avoiding scratches, wear or cracks on the surface of the magnet and the cover plate that may be caused by rigid contact, thereby protecting the integrity and performance of the magnet and the cover plate. Since the elastic buffer pad can evenly distribute pressure, the lamination process is smoother and more uniform. This helps to ensure that the fit between the magnet and the cover plate is tighter and more accurate, avoiding lamination defects such as bubbles and gaps caused by excessive or uneven local pressure, thereby improving the quality of lamination and the reliability of the product.

[0085] The elastic buffer pads made of rubber and silica gel also have good shock absorption and noise reduction effects. During the pressing process, the equipment may generate vibrations and noises. The elastic buffer pads can absorb part of the vibration energy, reduce the transmission of vibrations, and at the same time reduce the noises generated by vibrations and collisions, improving the working environment. Rubber and silica gel have a certain degree of flexibility and plasticity, and can adapt to the unevenness or minor shape differences on the surfaces of the magnet and the cover plate. Even if there are some slight bumps or irregularities on the surfaces of the magnet and the cover plate, the elastic buffer pads can closely fit on their surfaces, providing an effective pressing effect.

[0086] In this embodiment, the rolling element 13 is a ball. The support column 12 is provided with a mounting groove 14 adapted to the rolling element 13. The rolling element 13 can freely roll in the mounting groove 14 to reduce the friction with the turntable assembly 2.

[0087] During actual use, the ball can freely roll in the mounting groove 14. Compared with sliding friction, the frictional force of rolling friction is much smaller. When the turntable assembly 2 comes into contact with the ball and moves relatively, the rolling friction method can greatly reduce the frictional resistance between the two. This makes the turntable assembly 2 rotate more smoothly, reduces energy loss, and improves the operating efficiency of the equipment. Due to the reduction of the frictional force, the interference factors received by the turntable assembly 2 during rotation are reduced, and it can rotate more precisely according to the predetermined trajectory and angle. This is particularly important for some equipment with high requirements for rotation accuracy (such as precision instruments, automated production lines, etc.), and helps to improve the processing accuracy and product quality of the equipment.

[0088] The ball has a certain load-bearing capacity and can bear the weight of the turntable assembly 2 and the loads generated during operation. By reasonably designing the number, size, and installation method of the balls, the load distribution between the support column 12 and the turntable assembly 2 can be made more uniform, ensuring the stability and safety of the equipment during operation. This cooperation method between the rolling element 13 and the mounting groove 14 has strong adaptability. Appropriate ball specifications and quantities can be selected according to different equipment requirements and working conditions to meet the usage requirements under various working conditions.

[0089] In this embodiment, the frame 1 is provided with a loading rack 56. The material taking execution assembly 54 has a first support plate 541 arranged on the loading rack 56, a first driver 542 for driving the first support plate 541 to move, a second support plate 543 arranged on the first support plate 541, a second driver 544 for driving the second support plate 543 to reciprocate, an actuator 545 rotatably arranged on the second support plate 543, a third driver 546 for driving the actuator 545 to rotate. An elastic member 547 is arranged between the actuator 545 and the second support plate 543. The movement direction of the first support plate 541 and the movement direction of the second support plate 543 are arranged crosswise.

[0090] In actual use, the first driver 542 drives the first support plate 541 to move, and the second driver 544 drives the second support plate 543 to reciprocate, and the movement directions of the two are cross - arranged. This enables the material - taking execution assembly 54 to have the movement ability with multiple degrees of freedom in space. It can flexibly adjust its position in different directions, facilitating accurate arrival at the materials at different positions on the loading rack 56 for material - taking operations, greatly improving the flexibility and adaptability of material - taking, and meeting the material - taking requirements for different layouts and materials at different positions. The third driver 546 drives the actuator 545 to rotate, further increasing the movement flexibility of the actuator 545, enabling it to grasp the material at a suitable angle after reaching the material position, and improving the accuracy of material - taking.

[0091] The elastic member 547 is arranged between the actuator 545 and the second support plate 543. When grasping the material, the elastic member 547 can play a buffering role, avoiding damage to the material caused by excessive grasping force. At the same time, it can also compensate to a certain extent for the inaccurate grasping position caused by factors such as material position deviation, further improving the success rate and quality of material - taking. The rotation function of the actuator 545 and the presence of the elastic member 547 enable the material - taking execution assembly 54 to adapt to materials with different shapes, sizes, and materials. For materials with irregular shapes, the appropriate grasping part can be found by adjusting the angle of the actuator 545; for fragile or deformable materials, the buffering effect of the elastic member 547 can effectively protect the material, expanding the applicable range of the material - taking execution assembly 54.

[0092] In this embodiment, a plurality of openings are provided on the turntable base 75, and the plurality of openings are arranged in cooperation with a plurality of cover plate support assemblies 72. The lifting plate is driven by the lifting driver 732 to pass through the openings, causing the cover plate support assembly 72 to slide on the cover plate guiding assembly 71.

[0093] In actual use, by driving the lifting plate through the openings by the lifting driver 732 to push the cover plate support assembly 72 to slide on the cover plate guiding assembly 71, precise control of the movement of the cover plate support assembly 72 can be achieved. Compared with other possible driving methods, this cooperation of the openings and the lifting plate can more accurately position and drive the cover plate support assembly 72, thereby ensuring the position accuracy of the cover plate during transmission and loading, being beneficial to improving the fitting accuracy between the cover plate and the magnet, and guaranteeing the assembly quality of the product. The plurality of openings are arranged in cooperation with the plurality of cover plate support assemblies 72, enabling each cover plate support assembly 72 to have a corresponding driving structure, avoiding problems such as unstable movement or jamming of the cover plate support assembly 72 caused by unreasonable driving methods. This helps to improve the stability and reliability of the entire cover plate loading mechanism 7, reduce the occurrence frequency of equipment failures, and improve production efficiency.

[0094] Cooperating with other components (such as the rotary drive assembly 76, the second cam divider 77, etc.), this way of driving the cover support assembly 72 to slide through the opening and the lifting plate can enable the cover support assemblies 72 on each cover guiding assembly 71 to cooperate with the material transfer assembly in sequence, realizing the continuous feeding of the covers. In the automated production process, the continuous feeding function can greatly improve production efficiency, reduce manual intervention, and lower production costs. The opening is provided on the turntable base 75, and the lifting plate drives through the opening. This structural design makes the layout of the entire cover feeding mechanism 7 more compact, fully utilizes the space of the turntable base 75, avoids excessive space occupation by additional complex drive structures, is conducive to the miniaturization and integrated design of the equipment, and is suitable for use in scenarios with limited space in industrial production.
