Description

Technical Field

[0001] This application relates to the field of fabric processing technology, and in particular to a button fastening device. Background Technology

[0002] Button-attaching machines are specialized devices used to rivet and secure the various parts of a button (such as the face button, male and female buttons, etc.) and are widely used in the garment manufacturing industry. Existing button-attaching machines use a mechanical structure to push the button parts to designated positions and perform the riveting operation to complete the button assembly. These devices, to a certain extent, meet the basic needs of button assembly in garment production, especially in mass production, where they can improve production efficiency through automation or semi-automation.

[0003] However, existing button-fastening devices have shortcomings in terms of space utilization efficiency and synchronous conveying of different types of buttons. Current button-fastening devices employ a single push path or multiple sets of push components arranged side-by-side to convey different parts of the button to the riveting point for assembly. This design results in the device occupying a large horizontal space, especially when processing multiple types of buttons simultaneously (such as face buttons and male / female buttons). The side-by-side arrangement of the push components significantly increases the overall size of the device, increasing the space required in the production workshop and raising manufacturing and maintenance costs. Due to the dispersed layout of the push components, existing devices often require separate operation when conveying different types of buttons, making it difficult to achieve synchronous conveying and riveting of multiple fasteners. This leads to low production efficiency, especially when rapid switching between different button types or diversified production is required. Existing equipment cannot achieve efficient synchronous operation through programmed control, limiting its application in modern, flexible production environments.

[0004] To address the aforementioned issues, there is an urgent need for a button-attaching device that can efficiently and synchronously transport multiple types of buttons within a limited space. Summary of the Invention

[0005] The purpose of this application is to provide a button fastening device to address the shortcomings of existing button fastening devices mentioned in the background art in terms of space utilization efficiency and synchronous delivery of different types of buttons.

[0006] To achieve this objective, the present application adopts the following technical solution: A button fastening device, comprising: A control chassis, wherein the control chassis is provided with rivet points; The first pushing component includes a first support structure disposed on the control chassis, the first support structure corresponding to the riveting point, and a first pushing structure disposed on the first support structure for pushing the first fastener along the first support structure to the riveting point; The second pushing component includes a second support structure located directly above the first support structure. The second support structure is provided with a second pushing structure. The end of the second support structure away from the second pushing structure is provided with a docking slot. The second support structure is used to push the second fastener into the docking slot. The riveting assembly, installed on the control box and located directly above the riveting point, is used to move the second fastener on the mating slot to the riveting point and to perform riveting operations on the first fastener and / or the second fastener.

[0007] Furthermore, the first support structure includes a first support plate and a second support plate, with one end of the second support plate fixedly connected to the first support plate and the other end corresponding to the riveting point. The top surface of the first support plate and the bottom surface of the second support plate are located on the same horizontal plane. The first pushing structure includes a first sliding component, which is disposed on the first support plate.

[0008] Furthermore, the first sliding component includes a first track and a first slider. The first track is disposed on the first support plate, the first slider is slidably connected to the first track, and the top surface of the first slider is higher than the top surface of the second support plate.

[0009] Furthermore, it also includes a positioning component, which is disposed on the second support plate and includes two positioning plates. One end of each of the two positioning plates is provided with an arc-shaped positioning groove corresponding to the first fastener for positioning the first fastener. The length of the positioning plate is adapted to the sliding stroke of the first slider on the first track.

[0010] Furthermore, the first pushing structure also includes a first push rod, one end of which is fixedly connected to the first sliding assembly, and the other end is disposed on the second support plate; The first pushing structure further includes a fixed block, a transmission arm, and a first driving member. The fixed block has a first sliding cylinder at one end away from the first sliding assembly. The transmission arm has a rectangular hole corresponding to the first sliding cylinder. The sliding contact surface of the first sliding cylinder is slidably connected to the inner wall of the rectangular hole. The first driving member drives the transmission arm to perform a swing arm movement, thereby driving the first sliding assembly to drive the first push rod to perform a reciprocating movement.

[0011] Furthermore, a second sliding cylinder is provided on the side of the transmission arm away from the fixed block, and a transmission plate is provided on the sliding contact surface of the second sliding cylinder. The transmission plate is fixedly connected to the first driving member, and the first driving member drives the transmission arm to perform swing arm movement by driving the transmission plate.

[0012] Furthermore, the second support structure includes a third support plate and a fourth support plate. The third support plate is provided with a second track and a second slider. The second track is arranged in a direction perpendicular to the first support structure. The second slider is slidably connected to the second track. The second pushing structure is fixedly connected to the second slider. One end of the fourth support plate is fixedly connected to the end of the third support plate away from the second slider, and the other end extends to the docking slot.

[0013] Furthermore, the second pushing structure includes a second push rod and a second driving member. One end of the second push rod is connected to the second slider, and the other end faces the docking slot. The second driving member is used to drive the second slider to slide on the second track, thereby driving the second push rod to push the second fastener into the docking slot.

[0014] Furthermore, the riveting assembly includes a riveting head and a riveting drive. The riveting head is located directly above the riveting point and is connected to the riveting drive. The riveting drive can drive the riveting head to move downward, move the second fastener on the mating slot to the riveting point, and perform riveting operation on the first fastener and / or the second fastener.

[0015] Furthermore, it also includes a first stop and a second stop, the first stop being disposed on the first support structure and the second stop being disposed on the second support structure, both the first stop and the second stop including a fixed plate and a hook-shaped stop portion rotatably connected to the fixed plate.

[0016] Compared with the prior art, this application has the following beneficial effects: This application provides a button fastening device that, by placing a second pushing component directly above a first pushing component, ensures that both occupy the same projected area in the horizontal direction, significantly reducing the overall size of the device. This effectively lowers the space requirements of the production workshop and reduces the manufacturing and maintenance costs of the equipment. The first pushing component and the second pushing component independently push the first and second fasteners (such as face buttons and male and female buttons) to the riveting point. Through the coordinated work of the docking slot and the riveting component, precise positioning and efficient riveting operations of different types of buttons are achieved. This enables the simultaneous delivery and riveting of multiple fasteners, improving production efficiency and enhancing the flexibility of the equipment in diversified production. It is particularly suitable for modern production scenarios that require rapid switching between different button types. Attached Figure Description

[0021] To make the inventive objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] In the description of this application, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0023] The technical solution of this application will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] In one embodiment, please refer to Figures 1 to 6A button fastening device includes a control housing 1 with a riveting point 11; a first pushing assembly 2, including a first support structure 21 on the control housing 1, the first support structure 21 corresponding to the riveting point 11, and a first pushing structure 22 on the first support structure 21 for pushing a first fastener along the first support structure 21 to the riveting point 11; a second pushing assembly 3, including a second support structure 32 directly above the first support structure 21, the second support structure 32 having a second pushing structure 32, and a mating groove 12 at one end of the second support structure 32 away from the second pushing structure 32 for pushing a second fastener to the mating groove 12; and a riveting assembly 4, mounted on the control housing 1 and located directly above the riveting point 11, for moving the second fastener on the mating groove 12 to the riveting point 11, and for riveting the first fastener and / or the second fastener.

[0025] In this embodiment, the control housing 1 includes a control circuit for receiving operation commands and providing power to make each structure operate according to a preset program. The control housing 1 is provided with a riveting point 11, which is a key position for completing the riveting operation during the button-fastening process. The first pushing component 2 delivers the first fastener (such as a face fastener) to the riveting point 11, and includes a first support structure 21 and a first pushing structure 22. The first support structure 21 is fixed to the control housing 1 and corresponds to the position of the riveting point 11, that is, the spatial position of the first support structure 21 and the riveting point 11 matches, so that the first fastener can be delivered to the processing position. The first pushing structure 22 is used to drive the first fastener to move along the first support structure 21 to the riveting point 11. The first fastener can be a face fastener, which is the bottom or receiving part of the fastener. The first support structure 21 can be a guide rail or a groove to constrain the movement path of the first fastener. The first pushing structure 22 can be a pneumatic, hydraulic, or mechanical push rod, and the pushing of the fastener is achieved through program control. Guided by the first support structure 21, the first fastener can be delivered to the riveting point 11 along a stable path, avoiding offset or misalignment. The automated drive of the first pushing structure 22 reduces the complexity of manual operation and improves pushing efficiency. The structure of the second pushing component 3, which handles the second fastener (such as the male and female fasteners in the embodiment), is functionally complementary to the first pushing component 2. The second pushing component 3 includes a second support structure 32 and a second pushing structure 32. The second support structure 32 is located directly above the first support structure 21. The end of the second support structure 32 away from the second pushing structure 32 is provided with a docking slot 12 for receiving and positioning the second fastener. The function of the second pushing structure 32 is to push the second fastener into the docking slot 12, preparing it for subsequent riveting operations. The second fastener can be a male and female fastener, which is used in conjunction with a face fastener to form a complete button structure. The docking slot 12 serves to temporarily fix the second fastener. The second support structure 32 can be a track or platform suspended above the first support structure 21, with its opposite sides fixedly connected to the inner side of the protective housing on the control box 1. The layout of the first support structure 21 directly above it saves horizontal space, enabling the device to achieve synchronous transportation of the two types of fasteners in the vertical direction. Through the vertically stacked layout, the first pushing component 2 and the second pushing component 3 can work simultaneously in a limited space, greatly improving space utilization. The docking slot 12 enables the second fastener to be positioned, preventing displacement during transportation. The collaborative work of the second pushing component 3 and the first pushing component 2 enables parallel processing of different types of fasteners, thereby significantly improving production efficiency. The riveting component 4 is responsible for completing the riveting operation of the button. The riveting component 4 is installed on the control box 1 and located directly above the riveting point 11. It is responsible for moving the second fastener in the docking slot 12 to the riveting point 11, while simultaneously performing riveting operations on the first fastener and / or the second fastener.The riveting assembly 4 may include a riveting head 41 or a mold, which can complete the pressing of the fastener by mechanical, hydraulic or pneumatic drive, and can perform riveting operations on a single fastener or two fasteners according to actual needs.

[0026] In another embodiment, a feeding component is also included, which is respectively disposed at the pushing end position of the first support structure 21 and the second support structure 32, for automatically conveying the first fastener and the second fastener to the first support structure 21 and the second support structure 32 respectively. The feeding component may include a vibratory feeder, a conveyor belt and a corresponding positioning device.

[0027] It is worth noting that the feeding component and riveting component 4 in this embodiment can be any existing technical structure that can achieve the same function. For example, the feeding component can also use a robotic arm to grasp the fasteners to achieve automatic conveying. The robotic arm's movement path and grasping action are controlled by a preset program. In addition to the aforementioned mechanical, hydraulic or pneumatic drive methods, the riveting component 4 can also use an electric drive method, which drives the riveting head 41 to move up and down through a motor to achieve the pressing operation of the fasteners. No specific limitation is made in this embodiment.

[0028] In one embodiment, the first support structure 21 has a first support plate 211 and a second support plate 212. One end of the second support plate 212 is fixedly connected to the first support plate 211, and the other end corresponds to the riveting point 11. The top surface of the first support plate 211 and the bottom surface of the second support plate 212 are located on the same horizontal plane. The first pushing structure 22 includes a first sliding component 23, which is disposed on the first support plate 211.

[0029] In this embodiment, the first support structure 21 consists of a first support plate 211 and a second support plate 212, which are fixedly connected to form an integral support frame. The first support plate 211, as the main load-bearing part, provides the mounting base for the first sliding component 23. The second support plate 212 extends to the riveting point 11, allowing the first fastener to be guided to the processing position. The first support plate 211 and the second support plate 212 are connected to the top surface of the control box through support columns. The top surface of the second support plate 212 and the bottom surface of the first support plate 211 are on the same horizontal plane, which makes the connection between the two plates more stable. The height difference between them can accommodate the first sliding component 23, which pushes the first fastener along the first support plate 211 to the second support plate 212 through a sliding mechanism, and finally reaches the riveting point 11.

[0030] In one embodiment, the first sliding component 23 includes a first track 231 and a first slider 232. The first track 231 is disposed on the first support plate 211, the first slider 232 is slidably connected to the first track 231, and the top surface of the first slider 232 is higher than the top surface of the second support plate 212.

[0031] In this embodiment, the first sliding component 23 includes a first track 231 and a first slider 232. The first track 231 is fixedly mounted on the first support plate 211, forming a guide path for the movement of the first fastener. The first track 231 is a linear structure, providing stable sliding support for the first slider 232, allowing the first fastener to move in a predetermined direction during the pushing process. The first slider 232 is slidably connected to the first track 231, meaning the first slider 232 can reciprocate on the first track 231. This sliding connection reduces frictional resistance. The top surface of the first slider 232 is higher than the top surface of the second support plate 212, allowing the first slider 232 to directly contact the side of the second support plate 212 for a limiting effect during sliding, preventing deviation from the predetermined trajectory during movement. Through the cooperation of the first track 231 and the first slider 232, the first fastener can be guided and stably pushed. The fixed mounting of the first track 231 ensures the stability of the pushing path, avoiding path deviations caused by external vibrations or operational errors.

[0032] In one embodiment, a positioning component 5 is further included. The positioning component 5 is disposed on the second support plate 212 and includes two positioning plates 51. One end of each of the two positioning plates 51 is provided with an arc-shaped positioning groove 511 corresponding to the first fastener for positioning the first fastener. The length of the positioning plate 51 is adapted to the sliding stroke of the first slider 232 on the first track 231.

[0033] In this embodiment, the positioning component 5 is disposed on the second support structure 32, including two positioning plates 51. Each positioning plate 51 has an arc-shaped positioning groove 511 at one corresponding end for positioning the first fastener. The positioning component 5 is positioned on the second support plate 212. Its function is to fix and guide the first fastener using the arc-shaped positioning groove 511, ensuring accurate positioning of the first fastener when it moves to the riveting point 11, preventing offset or misalignment. The positioning component 5 includes two positioning plates 51, which are arranged opposite each other, each with an arc-shaped positioning groove 511 at one opposite end. Since button fasteners are typically circular or nearly circular, the arc-shaped positioning groove 511 matches the edge shape of the first fastener, forming a close contact surface, thus restricting the free movement of the first fastener in the horizontal direction. The arc-shaped positioning groove 511 design has high adaptability, accommodating first fasteners of different sizes or shapes. Simultaneously, the symmetrical arrangement of the two positioning plates 51 forms a stable clamping structure, maintaining the first fastener in a fixed posture during the pushing process. This clamping structure effectively prevents the first fastener from shifting due to vibration or external force during the pushing process, ensuring that the first fastener is aligned with the second fastener when it reaches the riveting point 11. The length of the positioning plate 51 is adapted to the sliding stroke of the first slider 232 on the first track 231. Through the matching of its length and sliding stroke, the arc-shaped positioning groove 511 can continuously guide and constrain the first fastener throughout the pushing process. This design avoids the first fastener from detaching from the control of the positioning groove during movement and also reduces positioning failure caused by excessively long or short pushing distances, thereby improving the operational stability and reliability of the device.

[0034] In one embodiment, the first pushing structure 22 further includes a first push rod 221, one end of which is fixedly connected to the first sliding assembly 23, and the other end is disposed on the second support plate 212; the first pushing structure 22 also includes a fixing block 222, a transmission arm 223, and a first driving member 225. The fixing block 222 has a first sliding cylinder 226 disposed at the end away from the first sliding assembly 23, and the transmission arm 223 has a rectangular hole 224 corresponding to the first sliding cylinder 226. The sliding contact surface of the first sliding cylinder 226 is slidably connected to the inner wall of the rectangular hole 224. The first driving member 225 drives the transmission arm 223 to perform a swing arm movement, thereby driving the first sliding assembly 23 to drive the first push rod 221 to perform a reciprocating movement.

[0035] In this embodiment, the first pushing structure 22 drives the first fastener to move along the first support structure 21 toward the riveting point 11. The first push rod 221 is a component that directly contacts the first fastener. One end of the push rod is fixedly connected to the first sliding assembly 23, and the other end extends to the second support plate 212, so that the first push rod 221 can directly act on the first fastener and push it toward the riveting point 11 through the movement of the sliding assembly. The fixing block 222 plays a supporting and guiding role in the first pushing structure 22. The end of the fixing block away from the first sliding assembly 23 is provided with a first sliding cylinder 226. The sliding cylinder is a transmission connection point and forms a sliding connection with the rectangular hole 224 on the transmission arm 223. The fixing block 222 provides a stable support point for the movement of the transmission arm 223. At the same time, through the cooperation of the sliding cylinder and the rectangular hole 224, the transmission arm 223 is allowed to slide relative to each other within a certain range, thereby effectively transmitting the power of the driving component to the push rod. The sliding contact surface between the sliding cylinder and the rectangular hole 224 optimizes friction performance, reduces energy loss during movement, and confines the sliding cylinder to the rectangular hole 224 for directional sliding, enabling the transmission arm 223 to drive the first push rod 221 when it swings. The first driving member 225 serves as the power source, driving the transmission arm 223 to perform swing arm movement. The swing of the transmission arm 223 is converted into the reciprocating motion of the first sliding component 23 through the sliding of the first sliding cylinder 226 within the rectangular hole 224. The first driving member 225 can be a motor, cylinder, or other power device. Its output power is converted into the reciprocating motion of the first sliding component 23 through the swing of the transmission arm 223, ultimately driving the first push rod 221 to move along the first support structure 21. The connection between the driving member and the transmission arm 223 can be achieved through a mechanical structure, such as gears, connecting rods, or cam mechanisms, to ensure efficient power transmission.

[0036] In one embodiment, a second sliding cylinder 227 is provided on the side of the transmission arm 223 away from the fixed block 222. A transmission plate 228 is provided on the sliding contact surface of the second sliding cylinder 227. The transmission plate 228 is fixedly connected to the first driving member 225. The first driving member 225 drives the transmission arm 223 to perform swing arm movement by driving the transmission plate 228.

[0037] In this embodiment, the transmission arm 223 serves as an intermediary connecting power input and output. Its two ends are connected to different sliding structures. One end interacts with the first sliding cylinder 226 through a rectangular hole 224, while the other end connects to the transmission plate 228 through a second sliding cylinder 227. This double-ended sliding connection design allows the transmission arm 223 to maintain stable force transmission during movement, while reducing friction and wear through the sliding structure. The second sliding cylinder 227 is installed on the side of the transmission arm 223 away from the fixed block 222, and its sliding contact surface is connected to the transmission plate 228. The design of the second sliding cylinder 227 ensures the stability of the transmission arm 223 when driven. Specifically, the transmission arm 223, transmission plate 228, and second sliding cylinder 227 are rotatably connected by a shaft. The output power of the first driving component 225 directly acts on the transmission plate 228, enabling the transmission plate 228 and the transmission arm 223 to rotate synchronously around the shaft. The sliding cylinder effectively disperses the force generated during movement, avoiding local stress concentration, and reduces direct friction between mechanical parts through sliding contact, extending the service life of the device. The first driving component 225 drives the transmission plate 228, which in turn drives the transmission arm 223 to perform a swing arm movement. This swing arm movement drives the first sliding component 23 and the first push rod 221 to complete the pushing task of the first fastener. The first driving component 225 can be a motor, a cylinder, or other device capable of providing linear or rotational power, thereby pushing the first push rod 221 to move along the first support structure 21 and delivering the first fastener to the riveting point 11.

[0038] In one embodiment, the second support structure 32 includes a third support plate 321 and a fourth support plate 322. The third support plate 321 is provided with a second track 35 and a second slider 36. The second track 35 is arranged in a direction perpendicular to the first support structure 21. The second slider 36 is slidably connected to the second track 35. The second pushing structure 32 is fixedly connected to the second slider 36. One end of the fourth support plate 322 is fixedly connected to the end of the third support plate 321 away from the second slider 36, and the other end extends to the docking slot 12.

[0039] In this embodiment, the second support structure 32 includes a third support plate 321 and a fourth support plate 322. A second track 35 and a second slider 36 are disposed on the third support plate 321. The second track 35 is arranged perpendicular to the first support structure 21, causing the spatial movement paths of the first fastener and the second fastener to form an intersecting structure, which facilitates docking at the riveting point 11. The fourth support plate 322 is connected to the third support plate 321, with one end fixed to the end of the third support plate 321 away from the second slider 36, and the other end extending to the docking groove 12. This allows the fourth support plate 322 to serve as the final guide channel for the second fastener, ensuring a stable position when the second fastener is pushed into the docking groove 12. The second track 35 and the second slider 36 are the core moving components of the second support structure 32. The second track 35, fixed to the third support plate 321, provides a path for the second slider 36 to slide. The second slider 36 is slidably connected to the second track 35, enabling smooth reciprocating motion on the second track 35. The second pushing structure 32 is fixedly connected to the second slider 36, meaning that the movement of the second pushing structure 32 is achieved through the sliding of the second slider 36 on the second track 35. This sliding connection allows the second pushing structure 32 to push the second fastener from its initial position into the docking slot 12. This design ensures high stability and controllability during the pushing process, as the movement of the second slider 36 is constrained by the second track 35, preventing potential deviations or jitters during the pushing process. One end of the fourth support plate 322 is fixed to the third support plate 321, and the other end extends directly into the docking slot 12, forming a continuous guiding structure. This allows the second fastener, when pushed by the second pushing structure 32, to directly reach the docking slot 12 along the path of the fourth support plate 322 without additional turning or adjustment. This linear guiding design reduces the resistance of the second fastener during movement and also reduces the risk of jamming or misalignment due to complex paths. The presence of the fourth support plate 322 also provides a stable support platform for the docking slot 12, so that the second fastener can be held in the predetermined position after reaching the docking slot 12, providing a positioning basis for subsequent riveting operations.

[0040] In one embodiment, the second pushing structure 32 includes a second push rod 33 and a second driving member 34. One end of the second push rod 33 is connected to the second slider 36, and the other end faces the docking slot 12. The second driving member 34 is used to drive the second slider 36 to slide on the second track 35, thereby driving the second push rod 33 to push the second fastener to the docking slot 12.

[0041] In this embodiment, one end of the second push rod 33 is connected to the second slider 36, and the other end faces the docking slot 12, allowing the second push rod 33 to directly contact the second fastener and push it to the designated position in the docking slot 12 through sliding motion. The connection between the second push rod 33 and the second slider 36 is a fixed connection, that is, the movement of the second push rod 33 is achieved through the sliding of the second slider 36 on the second track 35. The second driving member 34 is the power source of the second pushing structure 32, driving the second slider 36 to slide on the second track 35, thereby driving the second push rod 33 to complete the pushing action. The driving method of the second driving member 34 can be a motor, cylinder, or other mechanical driving device. The docking slot 12 is a receiving and positioning component for the second fastener, including a rectangular groove and a circular groove corresponding to the second fastener. The rectangular groove and the circular groove are connected, and the bottom of the circular groove is deeper than the rectangular groove, allowing the second fastener to fall into the circular groove through the rectangular groove. Elevating blocks are provided on both sides of the rectangular groove to limit the vertical displacement of the second fastener, ensuring that the second fastener falls accurately into the circular groove without shifting or popping out.

[0042] In actual production, the movement of the second push rod 33 is controlled by the second drive component 34. Push control can be achieved through programming or sensors, such as adjusting the push distance or speed according to the fastener size, thereby improving production efficiency and consistency. By adjusting the parameters of the second drive component 34 or changing the groove shape of the docking slot 12, the device can quickly adapt to fasteners of different specifications to meet diverse production needs.

[0043] In one embodiment, the riveting assembly 4 includes a riveting head 41 and a riveting drive 42. The riveting head 41 is located directly above the riveting point 11 and is connected to the riveting drive 42. The riveting drive 42 can drive the riveting head 41 to move downward, move the second fastener on the mating slot 12 to the riveting point 11, and perform riveting operation on the first fastener and / or the second fastener.

[0044] In this embodiment, the riveting assembly 4 completes the riveting of the first fastener, the second fastener, and the workpiece through mechanical action. The riveting head 41 is the actuating component of the riveting assembly 4, directly contacting the fastener and responsible for applying pressure to complete the riveting operation. The riveting head 41 is located directly above the riveting point 11, enabling it to accurately align with the engagement position of the first and second fasteners, avoiding riveting failure or fastener damage due to positional deviation. The riveting point 11 is fixedly connected to the protective housing on the control box 1. The positioning of the riveting head 41 directly above the riveting point 11 ensures that its movement path is consistent with the riveting point 11, thereby guaranteeing the stability of the fastener during the riveting process. The riveting drive component 42 is the power source of the riveting assembly 4, mechanically connected to the riveting head 41. It can be pneumatically, hydraulically, or electrically driven to provide sufficient torque and speed to drive the riveting head 41 to complete the pressing action. During the riveting process, the second fastener is moved from the mating slot 12 to the riveting point 11 and pressed together. During the riveting process, the riveting drive 42 controls the pressing speed and force of the riveting head 41 according to the preset program or sensor feedback, so as to avoid deformation or damage of the fastener due to excessive pressure, and also to prevent the riveting from being loose due to insufficient pressure.

[0045] In one embodiment, the system further includes a first stopper 6 and a second stopper 7. The first stopper 6 is disposed on the first support structure 21, and the second stopper 7 is disposed on the second support structure 32. Both the first stopper 6 and the second stopper 7 include a fixing plate 61 and a hook-shaped stopper 62 rotatably connected to the fixing plate 61.

[0046] In this embodiment, both the first stop 6 and the second stop 7 consist of two parts. A fixed plate 61 serves as the base, fixed to the corresponding support structure. A hook-shaped stop 62 is connected to the fixed plate 61 via a rotatable connection, allowing it to rotate around a fixed point under specific conditions. This rotatable connection can typically be achieved through hinges, pivots, or other mechanical connectors. The hook-shaped stop 62 is designed in a hook shape to block the fastener at a specific position, while being able to be pushed open by the push rod. The first stop 6 is mounted on the first support structure 21, and the second stop 7 is mounted on the second support structure 32. The positions of the first stop 6 and the second stop 7 are respectively associated with the movement paths of the first and second fasteners. Specifically, the stop is positioned between the positioning component 5 and the push rod, and its side corresponds to the feeding component, located between the feeding component (the mechanism responsible for providing the fastener) and the push rod (the mechanism responsible for pushing the fastener), controlling the timing of the fastener's entry. The side of the stop corresponds to the feeding assembly, directly blocking the fasteners in the feeding assembly and preventing them from entering the working area unexpectedly. The stop's function is to prevent the next fastener from entering the riveting point 11 or the mating slot 12. The feeding assembly continuously provides fasteners, and the push rod pushes them to the designated position for riveting. Without the stop's intervention, the next fastener might enter the working area before the current fastener has finished being pushed or riveted, causing fastener accumulation, misalignment, or device jamming. The stop effectively prevents this through its hook-shaped stop 62. The hook design locks the fastener, preventing it from moving forward. The rotatable connection between the hook-shaped stop 62 and the fixing plate 61 allows the push rod to directly push open the stop when pushing the current fastener, causing it to rotate upwards along the fixing plate 61, thus providing space for the current fastener to pass. This design combines blocking and release functions, preventing premature entry of fasteners without hindering the normal operation of the push rod. The hook-shaped stop part 62 of the stop component, through its flexible rotation design, can quickly move aside when the push rod applies force, reducing the resistance of the push rod. At the same time, it returns to its original position after the push rod completes the push and continues to block the next fastener, thereby improving the operating efficiency and stability of the device.
