Description

Technical Field

[0001] This invention relates to the field of automated assembly technology for electronic components, and in particular to an automated assembly device for cylindrical housings and insulating particles. Background Technology

[0002] In the large-scale, standardized manufacturing system of electronic components, the embedded riveting assembly process of insulating particles and cylindrical shells is a key assembly process that determines the core performance of components and the quality of finished products. This process mainly involves precisely embedding the insulating particles into pre-set assembly positions inside the cylindrical shell, and then locking them together through riveting and shaping to form an integrated assembly structure. The assembly accuracy and structural stability are directly related to the insulation protection performance, overall structural strength, shock resistance, and long-term reliability of electronic components, making it a core link in ensuring high-quality mass production of electronic components.

[0003] In existing technologies, to meet the assembly requirements of miniaturized and precision electronic components, cylindrical shells with multi-step structures are often used. The stepped limiting structure is used to initially position and embed the insulating particles, and then a general-purpose riveting device is used to complete the overall riveting and locking, thus achieving integrated assembly of the insulating particles and the cylindrical shell. This assembly method has a simple structure and strong adaptability, and can meet the basic assembly production needs of conventional electronic components. Therefore, it is widely used in the mass production of various small and medium-sized electronic components.

[0004] However, in actual large-scale production and application, the insulating particles are small in size, compact in volume, and thin in structure. Without an effective clamping and positioning structure, automated equipment cannot achieve accurate material picking, alignment, and embedding assembly. At present, most of the industry relies on manual assisted assembly or simple semi-automatic equipment to complete the assembly operation. The low degree of automation not only reduces the production assembly efficiency and makes it difficult to adapt to the needs of modern large-scale mass production, but also introduces human assembly errors, resulting in poor product assembly consistency.

[0005] Secondly, in the core processes of embedding the insulating particles and subsequent riveting and locking, the existing assembly process lacks a precise positioning and limiting structure and a uniform riveting control mechanism. On the one hand, manual or simple equipment assembly is prone to problems such as offset of the embedded position of the insulating particles, incomplete assembly, and misalignment or tilting; on the other hand, conventional riveting equipment suffers from uneven riveting pressure, uncontrollable riveting stroke, and offset of the force point, ultimately resulting in a large deviation in the embedding depth of the insulating particles inside the cylindrical shell, and difficulty in ensuring the coaxiality of the assembly between the insulating particles and the cylindrical shell, resulting in serious assembly dimensional errors.

[0006] In summary, the existing riveting assembly process for insulating particles and multi-step cylindrical shells suffers from numerous technical drawbacks, including low automation, poor assembly positioning accuracy, insufficient riveting uniformity, poor finished product consistency, and low yield. These shortcomings fail to meet the demands of high-precision, high-stability, and highly automated mass production. Therefore, there is an urgent need to develop a novel assembly structure and process to address the deficiencies of existing technologies and improve the assembly accuracy, structural stability, and mass production yield of electronic components.

Simultaneously, relying on the assembly component feeding mechanism, uniform orientation feeding of insulating particles is achieved. Combined with a rear-to-forward embedding method, this solves the technical problems of insulating particle alignment deviation, uneven embedding depth, and poor assembly coaxiality inherent in traditional manual and simple equipment assembly. Through the innovative adoption of an upper and lower swing arm opening and closing riveting structure, coupled with multiple circumferentially evenly distributed riveting heads, uniform riveting pressure can be applied to the cylindrical shell simultaneously from multiple directions. This eliminates defects such as uneven riveting force, workpiece skewing, and loose riveting caused by traditional single-point and single-sided riveting, improving the assembly accuracy, coaxiality, and structural riveting stability of the insulating particles and cylindrical shell. The entire system automates the entire process of feeding, positioning, embedding, and riveting, replacing manual assembly assistance, greatly improving assembly production efficiency and batch product assembly consistency, and effectively reducing assembly defect rates and production loss costs.

Detailed Implementation

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-18 In this embodiment of the invention, an automated assembly equipment for cylindrical shells and insulating particles is provided for embedding insulating particles 1 onto cylindrical shells 2 in the form of tape. The equipment includes a body 10, a support frame 11 horizontally mounted on the body 10, a transfer table 12 for carrying tape is provided on the front side of the support frame 11, and a tape translation conveying mechanism 20 located above the transfer table 12 is also installed on the front side of the support frame 11. The tape translation conveying mechanism 20 is used to drive the tape to move stepwise along the transfer table 12. A workpiece positioning mechanism 30 is also installed at the upper end of the support frame 11. The workpiece positioning mechanism 30 is used to position the cylindrical shell 2 on the tape onto the transfer table 12. The machine body 10 is also equipped with an assembly feeding mechanism 40, an assembly embedding mechanism 50, and a riveting point mechanism 60. The assembly feeding mechanism 40 is used to provide insulating particles 1 in a uniform orientation. The assembly embedding mechanism 50 is used to grab the insulating particles 1 in a uniform orientation and drive the grabbed insulating particles 1 from the rear of the transfer table 12 to the front to embed them into the positioned cylindrical shell 2. The riveting point mechanism 60 is used to rivet the cylindrical shell 2 from multiple evenly distributed orientations, thereby riveting and fixing the cylindrical shell 2 to the insulating particles 1. The riveting mechanism 60 includes a riveting seat 61 fixedly mounted on the body 10, a rotating shaft 62 disposed on the riveting seat 61, an upper swing arm assembly 63 rotatably connected to the rotating shaft 62, a lower swing arm assembly 64 rotatably connected to the rotating shaft 62, and a riveting power mechanism 65 fixedly mounted on the riveting seat 61. The riveting power mechanism 65 is used to push the front ends of the upper swing arm assembly 63 and the lower swing arm assembly 64 to press and engage. A positioning hole 66 matching the cylindrical outer shell 2 is provided between the upper swing arm assembly 63 and the lower swing arm assembly 64. A plurality of riveting heads 67 are evenly distributed in the positioning hole 66.

[0025] In the above technical solution, during operation, the tape conveyor 20 first drives the tape carrying the cylindrical shell 2 to complete the step-by-step precise feeding on the transfer table 12. This, combined with the workpiece positioning mechanism 30 at the upper end of the support frame 11, precisely limits and fixes the cylindrical shell 2 as it moves to the processing station, preventing workpiece offset and movement during assembly. Based on this, the assembly feeding mechanism 40 continuously outputs insulating particles 1 in a uniform orientation to the designated position, achieving standardized feeding of the insulating particles 1. Subsequently, the assembly embedding mechanism 50 grabs the standardized insulating particles 1 and smoothly embeds them into the positioned cylindrical shell 2 from the rear to the front of the transfer table 12, achieving the desired feeding of the insulating particles. 1. Precise alignment and embedded assembly; After the workpiece is embedded, the riveting point mechanism 60 is activated, and the upper swing arm assembly 63 and the lower swing arm assembly 64 are driven to rotate relative to each other around the rotating shaft 62 through the riveting power mechanism 65, and the front end is pressed together. The positioning hole 66 formed by the upper and lower swing arms is used to coaxially limit the cylindrical shell 2. Then, multiple riveting heads 67 evenly distributed in the positioning hole 66 are used to uniformly rivet the cylindrical shell 2 from multiple directions. Finally, the synchronous locking assembly of the cylindrical shell 2 and the insulating particle 1 is completed. The entire process of feeding, positioning, embedding and multi-point uniform riveting is completed automatically, realizing the automated assembly line operation of the tape-type cylindrical shell 2 and the insulating particle 1.

[0026] This technical solution, by adapting to the tape-type workpiece conveying mode and combining the tape-type translational conveying mechanism 20 with the workpiece positioning mechanism 30, achieves precise, continuous, and automated feeding and positioning of the cylindrical shell 2. Simultaneously, relying on the assembly part feeding mechanism 40, it ensures uniform feeding of the insulating particles 1. Combined with the rear-to-forward embedding method, it solves the technical problems of misalignment of the insulating particles 1, uneven embedding depth, and poor assembly coaxiality that exist in traditional manual and simple equipment assembly. Through the innovative use of an upper and lower swing arm opening and closing riveting structure, combined with multiple circumferentially evenly distributed riveting heads 67, uniform riveting pressure can be applied to the cylindrical shell 2 simultaneously from multiple directions, eliminating defects such as uneven riveting force, workpiece skewing, and loose riveting caused by traditional single-point riveting and single-sided riveting. This improves the assembly accuracy, coaxiality, and structural riveting stability of the insulating particles 1 and the cylindrical shell 2. The entire equipment achieves fully automated operation of feeding, positioning, embedding, and riveting processes, replacing manual assembly assistance, greatly improving assembly production efficiency and batch product assembly consistency, and effectively reducing assembly defect rate and production loss costs.

[0027] Please see Figure 6-7 Based on the above technical solution, it is further proposed that the upper swing arm assembly 63 includes a first upper swing arm 631 and a second upper swing arm 632 rotatably connected to the rotating shaft 62, and the lower swing arm assembly 64 includes a first lower swing arm 641 and a second lower swing arm 642 rotatably connected to the rotating shaft 62. The front ends of the first upper swing arm 631 and the first lower swing arm 641 are each provided with a first semicircular portion 601 that engages with each other. The front ends of the second upper swing arm 632 and the second lower swing arm 642 are each provided with a second semicircular portion 602 that engages with each other. A positioning hole 66 is formed between the two first semicircular portions 601. The riveting head 67 has a riveting post 671 that movably passes through the first semicircular portion 601 and a positioning hole 66 located between the two first semicircular portions 601. The abutting part 672 on the pressure column 671 is constrained between the first semicircular part 601 and the second semicircular part 602. The riveting power mechanism 65 is configured to first drive the first upper swing arm 631 and the first lower swing arm 641 to engage, and then drive the second upper swing arm 632 and the second lower swing arm 642 to engage. The transfer table 12 is provided with a notch 121 at the position corresponding to the riveting point mechanism 60, so that the first semicircular part 601 and the second semicircular part 602 can extend into the cylindrical shell 2. The engagement of the two first semicircular parts 601 is used to clamp the cylindrical shell 2, and the engagement of the two second semicircular parts 602 is used to drive the riveting head 67 to rivet the cylindrical shell 2.

[0028] This solution further configures the upper swing arm assembly 63 and the lower swing arm assembly 64 as two independently cooperating swing arm structures. The first semicircular portion 601, formed by the first upper swing arm 631 and the first lower swing arm 641, and the second semicircular portion 602, formed by the second upper swing arm 632 and the second lower swing arm 642, are engaged in a step-by-step manner. A torsion spring is used for reset between the first upper swing arm 631 and the first lower swing arm 641. Similarly, a torsion spring is used for reset between the second upper swing arm 632 and the second lower swing arm 642. Without external force, the first semicircular portion 601 on the first upper swing arm 631 and the second upper swing arm 632 is in the open state; based on this, a limiting structure is used, with the riveting column 671 movably passing through the first semicircular portion 601 and the abutment portion 672 limiting and constraining between the two sets of semicircular portions. At the same time, with the notch 121 of the transfer table 12, the riveting structure can accurately fit the workpiece position, and the riveting power mechanism 65 realizes the step-by-step operation logic of first clamping and positioning, and then riveting and forming. First, the first The semicircular part 601 first engages and clamps the cylindrical outer shell 2, enabling secondary precise coaxial positioning of the workpiece before riveting, eliminating minor workpiece offsets and gap wobble, and providing a precise reference for subsequent riveting processes. Then, the second semicircular part 602 engages and drives the riveting head 67 to precisely complete the riveting operation. The limiting constraint of the abutment part 672 ensures stable, offset-free, and jam-free movement of the riveting column 671, effectively avoiding problems such as workpiece misalignment, riveting misalignment, and uneven force that easily occur in traditional integrated riveting structures where positioning and riveting are performed simultaneously. This step-by-step positioning and riveting structure achieves separate and independent operation of the positioning and clamping processes, enabling higher precision positioning and smoother riveting action. It is also suitable for precise stationary operations of continuous tape-type workpieces, further improving the coaxiality, embedding depth consistency, and structural strength of the riveting assembly between the insulating particle 1 and the cylindrical outer shell 2, eliminating problems such as riveting loosening, workpiece deformation, and insulation failure from the structural root.

[0029] Please see Figure 5-7Based on the above technical solution, the riveting power mechanism 65 is further structurally optimized. The riveting power mechanism 65 includes a servo electric push rod 651 mounted on a riveting base 61 and a linkage push block 652 slidably connected to the riveting base 61. The linkage push block 652 is driven by the servo electric push rod 651. A first insert 653 and a second insert 654 of different lengths are provided on the linkage push block 652. Two inclined guide surfaces, upper and lower, are provided at the ends of the first insert 653 and the second insert 654. The first insert 653 is used to engage with the first... Between the swing arm 631 and the first lower swing arm 641, and through the inclined guide surface, the first upper swing arm 631 and the first lower swing arm 641 are driven. The second insert block 654 is used to dock between the second upper swing arm 632 and the second lower swing arm 642, and through the inclined guide surface, the second upper swing arm 632 and the second lower swing arm 642 are driven. The riveting power mechanism 65 achieves the docking of the first upper swing arm 631 and the first lower swing arm 641 first through the different lengths of the first insert block 653 and the second insert block 654, and then drives the second upper swing arm 632 and the second lower swing arm 642 to dock. By employing a servo electric actuator 651 in conjunction with a sliding linkage push block 652 as a unified power source, and setting a first insert 653 and a second insert 654 with different lengths on the linkage push block 652, and combining the upper and lower inclined guide surfaces at the ends of the inserts to drive the upper swing arm assembly 63 and the lower swing arm assembly 64 respectively, the timing linkage control is achieved by relying on the stroke difference of the long and short inserts. This eliminates the need for multiple independent drive elements and complex control programs, precisely realizing the step-by-step timing action of first driving the first upper swing arm 631 and the first lower swing arm 641 to close for clamping and positioning, and then driving the second upper swing arm 632 and the second lower swing arm 642 to close for riveting operations. This simplifies the overall transmission and control structure of the equipment, reduces manufacturing costs and the difficulty of later maintenance; simultaneously, the servo electric actuator... The 651 boasts advantages such as controllable stroke, uniform thrust, and high motion precision. Combined with an inclined push transmission method using a tilted guide surface, it can smoothly convert linear thrust into the rotational opening and closing motion of the swing arm. The transmission process is free from impact, jamming, and idle error, ensuring extremely high synchronization, stability, and repeatability of the swing arm's opening and closing motion. This effectively avoids problems such as motion jitter, stroke deviation, and timing disorder that exist in traditional cylinder and cam drive methods. This makes the process sequence of secondary precision positioning and riveting of workpieces more precise and controllable, further ensuring the consistency of clamping positioning accuracy and riveting pressure for each batch of products. It significantly reduces defects such as workpiece misalignment, incomplete riveting, and shell deformation caused by unstable power output, continuously improving component assembly accuracy, structural robustness, and mass production yield.

[0030] Please see Figure 8-11Based on the above technical solution, it is further proposed that the assembly feeding mechanism 40 is set in front of the transfer table 12. The assembly feeding mechanism 40 includes a feeding vibratory plate 41 fixedly installed on the machine body 10, a linear feeder 42 installed on the machine body 10, and a discharge component 43 fixedly installed at the discharge end of the linear feeder 42. The discharge component 43 has a discharge hole 44 that is connected to the linear feeder 42. The discharge hole 44 is used to provide insulating particles 1 in a uniform orientation. A needle cylinder 45 connected to the discharge hole 44 is also installed on the discharge component 43. The needle cylinder 45 is used to limit the insulating particles 1 in the discharge hole 44. By placing the assembly feeding mechanism 40 in front of the transfer table 12, a continuous automated feeding chain is formed through the feeding vibratory feeder 41, the linear feeder 42, and the discharge component 43. The vibratory feeder automatically sorts and neatly arranges the micro insulating particles 1, which are then conveyed at a constant speed by the linear feeder 42. Finally, the particles 1 are accurately discharged in a uniform orientation through the discharge hole 44 of the discharge component 43. At the same time, a needle cylinder 45 is set at the discharge hole 44 for limit locking, which can accurately control the discharge rhythm of a single insulating particle 1, effectively avoiding feeding abnormalities such as over-feeding, jamming, leakage, and cross-feeding. This achieves single-particle, directional, quantitative, and sequential accurate feeding of the insulating particles 1, which not only improves the stability and continuity of the feeding of micro insulating particles 1, providing a stable and reliable material basis for the subsequent precise gripping and alignment assembly of the embedding mechanism, but also eliminates problems such as assembly misalignment and incomplete embedding caused by feeding deviation, further improving the automation smoothness, assembly accuracy, and batch production stability of the overall assembly process.

[0031] Please see Figure 8-11Based on the above technical solution, it is further proposed that the component embedding mechanism 50 is located behind the transfer table 12. The component embedding mechanism 50 includes a first embedded ball screw linear module 51 fixedly installed on the machine body 10, a first fixed seat 52 powered by the first embedded ball screw linear module 51, a lifting cylinder 53 fixedly installed on the first fixed seat 52, a second fixed seat 54 powered by the piston end of the lifting cylinder 53, an air passage plate 55 installed on the second fixed seat 54, and a component embedding mechanism 50 installed on the first fixed seat 12. The two fixed bases 54 have a material-inserting cylinder 56 and a material-inserting pusher 57 that is powered to the material-inserting cylinder 56. The upper end of the air circuit plate 55 protrudes forward and has a boss 551 for docking with the cylindrical outer shell 2. A suction hole 552 is opened in front of the boss 551. The suction hole 552 is a through structure. The material-inserting pusher 57 is provided with a material-inserting push rod 571 that is axially docked with the suction hole 552. An expansion part 553 is provided inside the suction hole 552. The air circuit plate 55 is provided with an air passage 554 that docks with the expansion part 553. By arranging the component embedding mechanism 50 behind the transfer table 12, and relying on the first embedded ball screw linear module 51, the overall structure achieves high-precision horizontal displacement adjustment. Combined with the lifting cylinder 53, precise vertical alignment is achieved, enabling multi-dimensional precise movement of the entire mechanism and effectively meeting the precise docking requirements of the tape-making station. By setting a boss 551 with a through-hole suction hole 552 at the front end of the air circuit board 55, and combining it with the air passage 554 connecting to the suction hole 552 and the internal expansion part 553, the small insulating particles 1 can be stably sucked up using negative pressure adsorption. The expansion part 553 increases the adsorption cavity area and improves the adsorption adhesion. This effectively solves the problems of unstable gripping, easy detachment, and easy deviation of tiny insulating particles 1, ensuring that the insulating particles 1 are in the correct posture and constant position when picked up. At the same time, the inserting cylinder 56 drives the inserting push rod 571 to push the insulating particles 1 through the suction hole 552 axially, which can realize the coaxial, stable, and uniform forward pushing and inserting operation of the insulating particles 1. Compared with the traditional clamping type inserting structure, it avoids problems such as clamping deviation, damage to the insulating particles 1, and alignment deviation. The overall mechanism achieves high precision and high stability operation of the entire process of picking up, aligning, and inserting insulating particles 1 through the integrated structural design of precise positioning of the lead screw module, stable suction under negative pressure, and axial linear inserting.

[0032] In terms of structural layout, the discharge port 44 is located below the transfer table 12. The suction port 552 is horizontally aligned with the discharge port 44 by the retraction of the lifting cylinder 53, and horizontally aligned with the cylindrical shell 2 on the transfer table 12 by the extension of the lifting cylinder 53. The suction port 552 is driven by the first embedded ball screw linear module 51 to engage with the discharge port 44 or the cylindrical shell 2. The suction port 552 sucks up the insulating particles 1 from the discharge port 44 by adsorption. The suction port 552 is pushed into the positioned cylindrical shell 2 by the inserting push rod 571. By setting the discharge port 44 below the transfer table 12, the suction port 552 can achieve the desired effect. Below the conveying table 12, and relying on the horizontal displacement of the first embedded ball screw linear module 51 and the vertical extension stroke of the lifting cylinder 53, the suction hole 552 is precisely switched and aligned between the discharge hole 44 and the cylindrical shell 2. The equipment can first retract the lifting cylinder 53 to make the suction hole 552 horizontally align with the discharge hole 44 below, and use negative pressure adsorption to accurately pick up a single oriented insulating particle 1. Then, through the translation of the module and the extension of the lifting cylinder 53, the suction hole 552 with the adsorbed insulating particle 1 is precisely aligned with the cylindrical shell 2 that has been positioned on the conveying table 12. Finally, the embedded assembly is completed by axially pushing the insert push rod 571.

[0033] Please see Figure 3-4Based on the above technical solution, it is further proposed that a coaxiality detection mechanism 70 is installed on the machine body 10 at a position behind the transfer table 12. The coaxiality detection mechanism 70 includes a horizontal fine-tuning linear module 71 fixedly installed on the machine body 10, a third fixed seat 72 poweredly connected to the horizontal fine-tuning linear module 71, and a vision detection module 73 installed on the third fixed seat 72. The vision detection module 73 is used to detect the coaxiality between the cylindrical shell 2 and the insulating particles 1 after riveting and fixing. An assembly position detection mechanism 80 is also installed on the machine body 10 at a position behind the transfer table 12. The assembly position detection mechanism 80 includes a second embedded ball screw linear module 81 fixedly installed on the machine body 10, a fourth fixed seat 82 powered by the second embedded ball screw linear module 81, a sensor fixing fixture 83 installed on the fourth fixed seat 82, and a spring-loaded displacement sensor 84 installed on the sensor fixing fixture 83. The spring-loaded displacement sensor 84 makes contact with the insulating particles 1 riveted in the cylindrical shell 2 through the drive of the second embedded ball screw linear module 81. This solution further integrates a coaxiality detection mechanism 70 and an assembly position detection mechanism 80 behind the transfer table 12, constructing a comprehensive and high-precision automated assembly quality inspection system. The coaxiality detection mechanism 70, relying on the transverse fine-tuning linear module 71 to drive the vision inspection module 73, achieves precise workstation adaptation and fine-tuning alignment. Through non-contact visual imaging detection, it performs real-time precision inspection of the coaxiality of the riveted cylindrical shell 2 and the insulating particles 1, efficiently identifying various minor assembly misalignments and misalignment defects, avoiding the problems of low accuracy and high missed detection rate of manual inspection. Simultaneously, the assembly position detection mechanism 80 utilizes the second embedded ball screw linear module 81 to drive the spring-loaded displacement sensor 84 for precise displacement feeding. The sensor makes precise contact with the insulating particle 1, enabling high-precision detection of the actual embedding depth and assembly status of the insulating particle 1 inside the cylindrical shell 2. This accurately detects hidden assembly defects such as insufficient embedding, suspended assembly, and uneven depth. The dual detection mechanisms cooperate and complement each other for verification, allowing for comprehensive and accurate verification of the finished product assembly quality from two core dimensions: coaxiality accuracy and embedding assembly position. This achieves automated full-inspection screening of assembly defects, replacing the traditional manual sampling mode and improving detection accuracy and efficiency. Furthermore, a screening mechanism can be installed at the discharge end of the transfer table 12 to separate the finished products into good and defective products, thereby achieving fully automated assembly, inspection, and defective product rejection.

[0034] Please see Figure 2 , Figure 12-14Based on the above technical solution, a tape-and-reel translation conveying mechanism 20 is further proposed, comprising a translation cylinder 21 installed on the front side of the support frame 11, a multi-segment pushing mechanism 22 installed on the front side of the support frame 11 and arranged in a row laterally, and a linkage rod 23 connecting two adjacent pushing mechanisms 22; the pushing mechanism 22 includes a first linear guide rail 221 fixedly installed on the front side of the support frame 11, a pushing plate 222 slidably connected to the first linear guide rail 221, an inserting cylinder 223 fixedly installed in front of the pushing plate 222, and a power supply. The inserting plate 224 connected to the inserting cylinder 223 and the positioning pin 225 installed at the lower end of the inserting plate 224 are connected to the two adjacent pusher mechanisms 22 through the pusher plate 222 and the linkage rod 23. The translation cylinder 21 is used to drive the pusher plate 222 to move laterally. The positioning pin 225 is driven by the inserting cylinder 223 to engage with the tape on the transfer table 12, so that the translation cylinder 21 drives the tape to move laterally along the transfer table 12. A clearance groove 122 is provided on the transfer table 12 to cooperate with the positioning pin 225.

[0035] The tape has a continuous, uninterrupted long strip structure and cylindrical outer shells 2 uniformly connected to the front side of the long strip structure. A multi-segment pushing mechanism 22, in conjunction with linkage rods 23, forms an integrated synchronous conveying structure. A translation cylinder 21 provides unified conveying power, and each segment of the pushing mechanism 22 has its own independent first linear guide rail 221 for smooth sliding guidance. Insertion holes are provided on the tape structure to engage with positioning pins 225. The insertion cylinder 223 drives the insertion plate 224 to precisely insert and position the tape using the positioning pins 225. The long clearance grooves 122 on the transfer table 12 provide ample clearance space for the positioning pins 225, effectively preventing interference between the pins and the table. Through multi-segment pushing... The linkage transmission structure of the material feeding mechanism 22 enables multi-point uniform force traction and conveying of the tape, effectively preventing problems such as local stretching, offset, warping, and single workpiece positioning deviation during long-distance tape conveying. It ensures the synchronicity, straightness, and stability of the overall step-by-step translation of the tape. At the same time, the independent insertion and positioning method provides firm positioning and convenient disengagement. Combined with the workpiece positioning mechanism 30, it can accurately match the step-by-step assembly rhythm of the equipment, achieving high-precision and high-repeatability intermittent feeding of the tape. It effectively ensures the station accuracy of the cylindrical shell 2 after each feeding, providing a stable and accurate workpiece station foundation for subsequent processes such as embedding of insulating particles 1, riveting, and precision inspection, further improving the overall assembly consistency and mass production yield.

[0036] Please see Figure 2 , Figure 4 , 15-18, Based on the above technical solution, it is further proposed that workpiece positioning mechanisms 30 are provided at the positions of the fitting embedding mechanism 50, riveting point mechanism 60, coaxiality detection mechanism 70 and assembly position detection mechanism 80 on the transfer table 12. The workpiece positioning mechanism 30 includes a fifth fixed seat 31 installed on the upper end of the support frame 11, a positioning cylinder 32 installed on the fifth fixed seat 31, and a positioning plate 33 powered by the positioning cylinder 32. The positioning plate 33 is used to position the cylindrical shell 2 on the transfer table 12. In the design, the positioning plate 33 and the insert plate 224 are staggered. The positioning plate 33 is used to position the cylindrical shell 2 on the tape. The insert plate 224 cooperates with the strip structure on the tape. The two can be staggered to avoid conflict. The positioning plate 33 corresponding to the assembly insertion mechanism 50 is provided with a first positioning tooth 34 in a U-shape. The first positioning tooth 34 is configured to position and grip multiple adjacent cylindrical shells 2. A stripping cylinder 35 and a stripping plate 36 powered by the stripping cylinder 35 are also installed on the positioning plate 33. The stripping plate 36 pushes out the cylindrical shells 2 that are positioned and gripped in the first positioning tooth 34 by the drive of the stripping cylinder 35. Two sets of spaced-apart braided strips 37 are provided at the lower end of the positioning plate 33 corresponding to the riveting point mechanism 60. The braided strips 37 are used to press and position the braided portion on both sides of the cylindrical shell 2 when riveting. Specifically, the braided strips 37 are used to press the strip structure of the braided strip onto the transfer table 12, so that the braided strip located on the two braided strips 37 is straightened for processing by the riveting point mechanism 60; and the braided strips 37 and the insert plate 224 are staggered in front and behind. The lower end of the positioning plate 33 corresponding to the coaxiality detection mechanism 70 and the assembly position detection mechanism 80 is provided with a second positioning tooth 38 in a V-shape. The second positioning tooth 38 is configured to position multiple adjacent cylindrical shells 2.

[0037] In the above technical solution, the positioning cylinder 32 drives the positioning plate 33 to press down to achieve targeted locking and positioning of the cylindrical shell 2 at each workstation. The positioning structure is set differently according to the characteristics of different processes, which improves the adaptability and positioning reliability of each process. For the assembly part embedding mechanism 50, the positioning plate 33 with U-shaped first positioning teeth 34 is used, which can simultaneously clamp and position multiple sets of adjacent cylindrical shells 2. Combined with the structure of the stripping cylinder 35 and the stripping plate 36, the workpiece stuck in the first positioning teeth 34 can be accurately and smoothly pushed out, effectively solving the problem of dense workpiece positioning jamming and unloading difficulties, and ensuring the smoothness of continuous assembly. For the riveting point machine Structure 60 uses two sets of spaced-apart pressing strips 37 to press the braided areas on both sides of the riveting point, which can offset the workpiece movement and braided deformation caused by the instantaneous impact force of riveting, avoid workpiece displacement and braided warping deformation during riveting, and ensure the accuracy of riveting. For the inspection process, V-shaped second positioning teeth 38 are used to align and position multiple sets of workpieces. Utilizing the automatic centering characteristic of the V-shaped structure, it effectively ensures that the coaxial reference of the workpiece is consistent with that of the coaxiality detection mechanism 70 and the assembly position detection mechanism 80, avoiding problems such as detection data deviation and misjudgment caused by positioning eccentricity. This multi-station differentiated dedicated positioning structure can be adapted to the working force characteristics and accuracy requirements of each process.
