Description

Technical Field

[0001] This utility model belongs to the technical field of electronic equipment manufacturing, specifically relating to an electromagnetic shielding disk assembly device, used to achieve precise, efficient and automated assembly between the electromagnetic shielding disk and the base. Background Technology

[0002] In the manufacturing process of electronic equipment, electromagnetic shielding panels, as important electromagnetic compatibility (EMC) components, are widely used in various applications requiring electromagnetic shielding. The main function of electromagnetic shielding panels is to prevent or reduce electromagnetic wave leakage and interference, thereby protecting sensitive electronic components inside the equipment from the influence of the external electromagnetic environment. However, currently, the assembly of electromagnetic shielding panels largely relies on manual operation, which presents the following problems:

[0003] Inaccurate positioning: During manual installation, the matching of the shielding plate and the base often depends on the operator's experience and skills, making it difficult to guarantee the precise position of each assembly, resulting in unstable assembly quality;

[0004] Uneven force: The force applied manually is difficult to control precisely, which can easily lead to uneven force on the shielding plate, affecting the tightness of the fit between it and the base, and even causing the shielding plate to deform or be damaged.

[0005] Height tolerance and parallelism are difficult to control: During manual assembly, it is difficult to accurately control the height tolerance and parallelism between the shielding plate and the base (usually within ±0.05mm), which can easily affect the overall performance and stability of the equipment.

[0006] Low production efficiency: Manual assembly is slow and cannot meet the needs of large-scale production, increasing production costs and time.

[0007] Existing technologies include research addressing numerous problems with manual assembly operations. For example, patent CN219465347U – an automatic assembly device for EMI shielding materials and screws – uses a suction head and guide post for positioning, but its structure relies on a vibratory feeder, which cannot meet the rigid structure of electromagnetic shielding discs and the high-efficiency assembly requirements of multiple riveting points. Another example is patent CN219704056U – an automatic assembly device for protective sleeves, which achieves automation through a vibratory feeder and gripper material transfer components. However, it adopts a linear multi-station layout, occupies a large space, and the gripping and riveting are performed in separate steps, making it difficult to achieve high-precision synchronous positioning.

[0008] In summary, existing automated assembly devices have limited automation functions, making it difficult to automate the entire process of electromagnetic shielding disc assembly, from gripping to riveting. They also struggle to meet the high-efficiency, high-precision assembly requirements of electromagnetic shielding discs and lack a vertically intersecting layout design for the electromagnetic shielding disc and its base, resulting in redundant transmission paths and low station switching efficiency during assembly. Therefore, a new technical solution is needed to address these issues. Utility Model Content

[0009] The purpose of this utility model is to provide an electromagnetic shielding disk assembly device to solve the problems mentioned in the background art. The current automatic assembly device is difficult to automate the entire process of electromagnetic shielding disk from gripping to riveting, and it is also difficult to meet the requirements of high efficiency and high precision assembly of electromagnetic shielding disk. Furthermore, it lacks a vertical cross-layout design for electromagnetic shielding disk and base, resulting in problems such as redundant transmission paths and low workstation switching efficiency during the assembly process.

[0010] To achieve the above objectives, this utility model provides the following technical solution: an electromagnetic shielding disk assembly device, comprising a base guide rail and a shielding disk guide rail. The end of the base guide rail is located above the end of the shielding disk guide rail in the vertical direction, and the two form a vertically intersecting layout in three-dimensional space at their intersection area. A base is provided on the inner side of the intersection area. The base integrates a gripping and riveting mechanism. The gripping and riveting mechanism includes a rotating arm that rotates around the vertical axis of the base and a gripping module and a riveting module fixed to the end of the rotating arm. The gripping module is hinged to the end of the riveting module. Multiple bases are evenly arranged along the length of the base guide rail. The bases are fixed to the positioning seats of the base guide rail. Multiple shielding disks that match the bases are correspondingly arranged on the shielding disk guide rail. The shielding disks are positioned on the positioning blocks on the shielding disk guide rail by riveting posts. Multiple shielding disks are sequentially assembled onto the corresponding bases by gripping by the gripping module, transmission by the rotating arm, and riveting by the riveting module.

[0011] Furthermore, one end of the rotating arm is threaded to the upper part of the vertical shaft of the base, and a servo motor is connected to its bottom plane and driven by the servo motor to rotate around the vertical shaft of the base. A support plate is vertically fixed on the end face of the other end of the rotating arm, and the upper part of the side surface of the support plate away from the rotating arm is fixedly connected to the riveting module.

[0012] Furthermore, the riveting module includes a riveting cylinder fixed to the upper part of the side surface of the support plate. The bottom end of the riveting cylinder is fixedly connected to an installation shaft. The installation shaft passes through a fixed plate fixed in the lower part of the support plate and its bottom end is hinged to the gripping module. A stroke fine-tuning nut is sleeved at the connection between the installation shaft and the upper part of the fixed plate, and a guide sleeve is sleeved at the connection between the installation shaft and the lower end of the fixed plate.

[0013] Furthermore, the gripping module includes multiple claws hinged to the bottom end of the mounting shaft axially. The inner side of each claw elastically abuts against a spring piece. The upper end of the spring piece is fixed to the bottom end of the mounting shaft axially upward, and its lower end is bent inward to form a hook. The hook is embedded in a groove at the lower end of the inner side of the claw. The upper end of each claw is hinged to the bottom end of the mounting shaft axially upward, and its lower end has a positioning groove. The upper end of the positioning groove is horizontally fitted with a positioning boss. The outer center of the positioning boss has an arc-shaped positioning hole, and a transverse groove is left between its bottom plane and the lower end face of the positioning groove. The lower end face of the positioning groove extends outward to form a hook.

[0014] Furthermore, the center of the shielding disk is provided with a ring that cooperates with the transverse slot and the hook. The upper end surface of the ring is vertically upwardly provided with a positioning post that matches the arc positioning hole, and the lower end surface of the ring is vertically downwardly provided with multiple riveting posts. The riveting posts are provided one-to-one with the riveting holes on the upper end surface of the base.

[0015] Furthermore, a claw closing cylinder is fixed through the fixed plate and arranged parallel to the riveting cylinder. The bottom end of the piston rod of the claw closing cylinder is fixed with a guide plate arranged parallel to the fixed plate. A guide post is vertically fixed on each side of the guide plate and passes through the corresponding position of the fixed plate. The guide plate moves up and down directly below the fixed plate through the guide post and the claw closing cylinder. The guide plate is provided with a limiting hole that passes through and limits the claw. The claw is retracted into the limiting hole through the claw closing cylinder and riveted to the ring of the shielding disk by the riveting cylinder.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model utilizes a three-dimensional vertical intersecting layout formed by the base guide rail and the shielding disk guide rail in the intersection area, with a base set in the intersection area. This design not only optimizes space utilization but also enables the gripping, conveying, and riveting actions to be completed efficiently within a compact space. Compared to linear or parallel layouts, this layout reduces the space occupied by the device, improves the integration and flexibility of the production line, and also helps reduce path redundancy during the conveying process, improving assembly efficiency. It is particularly suitable for high-frequency, high-volume production scenarios. By integrating the gripping module and the riveting module at the end of the same rotating arm to form an integrated gripping and riveting mechanism, the gripping, conveying, and riveting actions of the shielding disk are realized. The continuous and seamless connection achieves fully automated operation, avoiding the tedious steps of multiple positioning and workstation changes required in the traditional assembly process, significantly improving overall assembly efficiency, reducing error accumulation during assembly, and improving assembly accuracy and stability. Utilizing the rotation of the rotating arm, the shielding disk is transferred from the shielding disk guide rail to the base guide rail. Compared with traditional linear transmission or robotic arm gripping transmission methods, this is more flexible and efficient. It can not only accurately control the position and orientation of the shielding disk, providing strong support for subsequent riveting operations, but also adapt to the assembly requirements of electromagnetic shielding disks and bases of different specifications and models, achieving efficient and high-precision assembly of electromagnetic shielding disks.

[0018] 2. This utility model utilizes the fast response speed of the servo motor to quickly adjust the position of the rotating arm to adapt to the needs of different assembly rhythms. It also improves the positioning accuracy and repeatability of the rotating arm, making the assembly process more stable and reliable. By designing a stroke fine-adjustment nut at the connection between the mounting shaft and the upper end of the fixed plate, the operator can adjust the downward stroke of the riveting cylinder according to actual needs, thereby adjusting the height of the chuck and ensuring the riveting quality between the shielding plate and the base.

[0019] 3. This invention utilizes the elastic contact of the spring sheet to enable the claw to automatically adjust its position when gripping the shielding disk, adapting to the slight unevenness on the surface of the shielding disk. Based on this, the design of bending the lower end of the spring sheet inward to form a hook enhances the connection stability between the claw and the spring sheet, preventing the phenomenon of falling off during the gripping process. Through the precise cooperation of the positioning boss, arc positioning hole, transverse groove, and hook with the positioning post, ring, and riveting post on the shielding disk, the stability and accuracy of the shielding disk during the assembly process are ensured, realizing high-precision positioning of the shielding disk and reducing assembly failure or defect rate caused by inaccurate positioning.

[0020] 4. The present invention utilizes the limiting hole to limit the claw to the guide plate, so that the claw can maintain a stable posture and position when gripping and releasing the shielding disk, effectively preventing the claw from deviating or shaking during the movement, and also ensuring the precise engagement of the shielding disk's annular feature with the transverse slot. On this basis, the guide plate is used to precisely control the claw by closing the cylinder, ensuring the synchronicity and consistency of the claw during the gripping process.

[0021] 5. The assembly device of this utility model is not only suitable for assembling electromagnetic shielding disks and bases of specific specifications and models, but also has a certain degree of adaptability and flexibility. By adjusting the relevant parameters of the gripping module and the riveting module, it can adapt to the assembly requirements of electromagnetic shielding disks and bases of different sizes and shapes. It can also be seamlessly connected with other automated production lines to further optimize and upgrade the production process. Attached Figure Description

[0031] The following embodiments are used to further illustrate the content of this utility model, and do not limit the application of this utility model.

[0032] Please see Figures 1-8 This utility model provides an electromagnetic shielding disk assembly device, including a base guide rail 1 for base transmission and a shielding disk guide rail 2 for shielding disk 10 transmission (the movement trajectory of the shielding disk guide rail is reciprocating from right to left). The end of the base guide rail 1 is located above the end of the shielding disk guide rail 2 in the vertical direction, and the two form a vertical cross layout in three-dimensional space in the intersection area. The inner side of the intersection area is provided with a base 3 for fixing the gripping and riveting integrated mechanism. The base 3 integrates a gripping and riveting integrated mechanism for realizing gripping and riveting actions. The gripping and riveting integrated mechanism includes a rotating arm 4 that rotates around the vertical axis 301 of the base 3, a gripping module 5 fixed to the end of the rotating arm 4 for gripping the shielding disk 10, and a riveting module 6 for riveting the shielding disk 10 to the base 8. The gripping module 5 is hinged to the end of the riveting module 6 to realize the linkage of gripping and riveting actions.

[0033] Multiple positioning seats 7 are evenly arranged along the length of the base guide rail 1. Each positioning seat 7 is fixed with a base 8. The upper end face of the base 8 is provided with a riveting hole 801 for installing the shielding plate 10. The base guide rail 1 is driven by a motor (the functions and structures of conventional equipment such as motors are well known in the art, and the connection settings are also common knowledge, so they will not be described in detail here, and are not shown in the attached drawings) to move back and forth from back to front, ensuring that the base 8 is transported to the assembly station according to the preset rhythm.

[0034] The shielding disk guide rail 2 has multiple positioning blocks 9 evenly arranged along its length, and each positioning block 9 positions a shielding disk 10. The center of the shielding disk is provided with a ring 1001. Multiple positioning posts 1002 are vertically arranged upward on the upper end surface of the ring 1001, and multiple riveting posts 1003 corresponding to the riveting holes 801 are vertically arranged downward on its lower end surface. The shielding disk guide rail 2 is also driven by a motor to move back and forth from right to left and form a vertical cross layout with the base guide rail 1. Before installation, the shielding disk 10 is embedded in the corresponding hole of the positioning block 9 by its riveting posts 1003 to ensure the stability of the shielding disk 10 during the gripping process.

[0035] Please see Figures 1-6 One end of the rotating arm 4 is fixed to the upper part of the vertical shaft 301 of the base 3 by a threaded connection, and its bottom plane is connected to the servo motor 11 (selected as a position rotation servo motor), so that it is driven by the servo motor 11 to rotate around the vertical shaft 301. The other end face of the rotating arm 4 is vertically fixed with a support plate 12 for fixing the gripping module 5 and the riveting module 6.

[0036] A riveting cylinder 601 of the riveting module 6 is fixed to the upper part of the side surface of the support plate 12 away from the rotating arm 4. The bottom end of the riveting cylinder 601 is fixedly connected to a mounting shaft 602 for mounting claws 501. The mounting shaft 602 passes through the fixing plate 13 in the lower part of the support plate 12, and the downward stroke is adjusted by the stroke fine-tuning nut 14 threaded at the connection between the mounting shaft 602 and the upper end of the fixing plate 13 to ensure the riveting quality between the shielding disk 10 and the base 8. A guide sleeve 15 for stroke guidance is sleeved at the connection between the mounting shaft 602 and the lower end of the fixing plate 13. The bottom end of the mounting shaft 602 is connected to multiple claws 501 of the gripping module 5 (such as...). Figure 2 (The diagram shows four jaws 501 as an example) Hinged together, the jaws 501 are hinged to the bottom end of the mounting shaft 602 via pins;

[0037] The inner side of the claw 501 is elastically contacted by a spring piece 16. The upper end of the spring piece 16 is fixed to the bottom end of the mounting shaft 602 and axially upward, while its lower end is bent inward to form a hook 1601. The hook 1601 is embedded in the groove 5011 at the lower end of the inner side of the claw 501. The lower end of the outer side of the claw 501 is provided with a positioning groove 17. The upper end of the positioning groove 17 is horizontally embedded with a positioning boss 18. The middle of the outer side of the positioning boss 18 is provided with an arc positioning hole 1801 for the positioning post 1002 to be inserted. A transverse groove 5012 for the ring 1001 to be inserted is left between its bottom plane and the lower end face of the positioning groove 17. The lower end face of the positioning groove extends to form a hook 19 for supporting the shielding plate 10.

[0038] A claw closing cylinder 20 is fixed through the fixed plate 13, which is parallel to the riveting cylinder 601 and is used to control the retraction of the four claws 501. A guide plate 21 is fixed at the bottom of the piston rod of the claw closing cylinder 20, which is parallel to the fixed plate 13 and is used to assist the claw closing cylinder 20 in retracting the claws 501. A guide post 22 is fixed vertically on each side of the guide plate 21, which passes through the corresponding position of the fixed plate 13 and is used for guidance. The guide plate 21 moves up and down directly below the fixed plate 13 through the guide post 22 and the claw closing cylinder 20.

[0039] The guide plate 21 has a limiting hole 2101 that penetrates the claw 501, and the side wall of the limiting hole 2101 has a locking hole 23 that matches the slope of the claw 501 and limits its movement. The claw 501 is retracted into the limiting hole 2101 by the claw closing cylinder 20 with the assistance of the locking hole 23, and is riveted to the ring 1001 of the shielding plate 10 by the riveting cylinder 601.

[0040] The working principle and usage process of this utility model are as follows: Figures 1-8 As shown, after the electromagnetic shielding disk assembly device is assembled, the operator installs the entire electromagnetic shielding disk assembly device onto the electronic manufacturing equipment (the functions and structures of conventional equipment such as electronic manufacturing equipment are well known in the field, and the connection settings are also common knowledge, so they will not be explained in detail here, nor are they shown in the attached drawings). The purpose is to solve the core problems of low automation, insufficient positioning accuracy, and poor adaptability in the existing technology through spatial layout optimization, functional integration design, and high-precision mechanical structure innovation, thereby realizing the efficient and high-precision assembly of the electromagnetic shielding disk.

[0041] When an electromagnetic shielding disk needs to be installed on electronic manufacturing equipment, the operator first positions and fixes the base 8 and the shielding disk 10 onto the base guide rail 1 and the shielding disk guide rail 2 respectively using the positioning seat 7 and the positioning block 9. Then, the base guide rail 1 and the shielding disk guide rail 2 are moved back and forth from back to front and from right to left respectively by motor drive until they are conveyed to the intersection of the two workstations according to the rhythm. The servo motor 11 drives the rotating arm 4 to rotate the gripping and riveting integrated mechanism 90° to the right (i.e., the direction of the shielding disk guide rail 2) until it reaches above the shielding disk 10 (e.g., as shown in the image). Figure 8 (As shown in the first picture), and then control the riveting cylinder 601 to drive the chuck 501 to press down (as shown in the first picture). Figure 8(As shown in the second figure), at this time, the chamfer at the front of the hook 19 will be squeezed by the edge of the inner hole of the ring 1001. The claw 501 will retract under the squeezing action. The claw 501 will continue to descend under the control of the riveting cylinder 601 until the transverse groove 5012 of the claw 501 matches the feature of the ring 1001. Then, using the elastic resistance of the spring piece 16, the claw 501 will expand outward under the elastic action. At this time, the transverse groove 5012 of the claw 501 will be locked on the inner wall of the ring 1001 of the shielding disk 10. On the inner side of the ring 1001 of the shielding disk 10, the upper surface of the hook 19 abuts against the lower surface of the ring 1001, the lower surface of the positioning boss 18 abuts against the upper surface of the ring 1001, and the arc positioning hole 1801 is engaged with the positioning post 1002 on the upper surface of the ring 1001, thus completing the gripping of the shielding disk 10. Then, the servo motor 11 drives the rotating arm 4 to rotate the gripping and riveting integrated mechanism 90° to the left (i.e., the direction of the base guide rail 1), so that the shielding disk 10 gripped by the claw 501 is moved to the top of the base 8 under the rotation of the rotating arm 4 (e.g., as shown in the image). Figure 7 The first picture and Figure 8 (As shown in the third figure), then the riveting cylinder 601 is controlled to drive the chuck 501 to press down again. At this time, the lower surface of the positioning boss 18 will apply pressure to the ring 1001 of the shielding disk 10, so that the riveting post 1003 of the shielding disk 10 can be pressed into the riveting hole 801 of the base 8 under this pressure (as shown in the third figure). Figure 7 The second picture and Figure 8 As shown in the fourth figure, the riveting of the shielding disk 10 is completed. Finally, the piston rod of the control claw closing cylinder 20 extends downward and drives the guide plate 21 to move downward. At this time, the limiting hole 2101 and the oblique locking hole 23 of the guide plate 21 will press the outer surface of the claw 501 under the downward movement, causing the locking hook 19 of the claw 501 to retract inward (as shown in the figure). Figure 8 (As shown in the fifth figure), thereby disengaging the hook 19 from the ring 1001 of the shielding disk 10 (as shown in the fifth figure). Figure 7 As shown in the third figure, the automatic release action is completed. During the release action, the hook 1601 of the spring piece 16 is inserted into the inner groove of the claw 501. When the spring piece 16 pushes the hook 19 open, the hook 1601 can hold the hook 19, thus avoiding the problem of the hook 19 opening at too large an angle.

[0042] When the riveting height changes, the riveting cylinder 601 is adjusted by rotating the stroke fine-tuning nut 14 to control the downward stroke of the mounting shaft 602, thereby controlling the height position of the chuck 501 and ensuring that the riveting height tolerance is controlled within ±0.05mm.
