Abstract
Description
Technical Field
[0001] This application relates to the field of fabric processing technology, and in particular to a pressure-resistant button fastening device. Background Technology
[0002] Fastener-attaching equipment is widely used in the clothing, leather goods, and packaging industries to quickly fix fasteners to material surfaces for connection or decoration. Existing fastener-attaching equipment uses mechanical transmission or pneumatic systems to drive a stamping rod to complete the stamping and fixing operation. This equipment significantly improves processing efficiency in industrial production and meets the needs of mass production.
[0003] Existing fastening equipment has significant shortcomings in operational safety, particularly in preventing accidental hand injuries to operators (i.e., the "hand injury problem"), lacking effective protection mechanisms. This safety deficiency poses a considerable risk to the equipment in high-intensity or long-term operating environments, limiting its further promotion and application in modern production. In existing technologies, fastening equipment typically employs simple mechanical or pneumatic drives, using the up-and-down movement of a stamping rod to secure the fastener. Some equipment is equipped with basic detection devices, such as a single limit switch or photoelectric sensor, to monitor the movement of the stamping rod.
[0004] However, these devices have limited functionality and struggle to effectively identify and respond to anomalies within the operating area. For instance, when an operator's hand accidentally enters the stamping area, existing equipment often fails to detect and interrupt the stamping process in time, resulting in a high risk of the operator's hand being struck by the stamping rod. This inadequate safety protection not only increases the probability of operator injury but can also cause production interruptions, impacting overall production efficiency and the company's safety management. Summary of the Invention
[0005] The purpose of this application is to provide a pressure-resistant button fastening device to solve the technical problem mentioned in the background art that existing button fastening devices lack an effective protection mechanism to prevent accidental injury to the operator's hands.
[0006] To achieve this objective, the present application adopts the following technical solution: A pressure-resistant button fastening device, comprising: A workbench, on which a chassis body is mounted, and a first sensor and a second sensor are mounted on the side of the chassis body; A buckle mechanism is provided on the front of the main body of the chassis, including a stamping rod and a slider. An elastic element is sleeved on the outer surface of the stamping rod. The slider is connected to the stamping rod. A drive mechanism is provided at the end of the stamping rod away from the worktable. A linkage mechanism is provided on the side of the main body of the chassis, and one side of the linkage mechanism abuts against the slider. When the linkage mechanism drives the slider to move closer to the worktable, it drives the stamping rod to move down synchronously, triggering the first and second sensors. Then, the drive mechanism drives the stamping rod to perform a stamping and buckling operation on the fastener placed on the worktable.
[0007] Furthermore, it also includes a foot pedal, which is connected to the linkage mechanism. The foot pedal includes a foot pedal body and a connecting component. The foot pedal body is connected to the linkage mechanism through the connecting component. Stepping on the foot pedal body can drive the linkage mechanism to move.
[0008] Furthermore, the linkage mechanism includes a first link and a second link, both of which are connected to the side of the main body of the chassis via a pivot; one end of the first link is connected to the foot pedal, and the other end abuts against one end of the second link.
[0009] Furthermore, the linkage mechanism also includes an abutment plate, the first end of which is fixedly connected to the first link, and the second end of which is provided with a first guide ring. The first guide ring is connected to the second end of the first link via a rotating shaft. The first guide ring is used to slide along the outer surface of the second link when the first link moves.
[0010] Furthermore, the linkage mechanism also includes a first limiting member, which is disposed on the side of the second link close to the first link. The first limiting member is used to block the first guide ring when it slides along the outer surface of the second link to a specific position, thereby limiting the relative range of motion of the first link and the second link.
[0011] Furthermore, the buckling mechanism also includes a vertical track, which is disposed on the front of the main body of the chassis, and the slider slides on the vertical track; a second limiting member is also disposed on the vertical track, which is used to limit the sliding stroke of the slider on the vertical track, wherein the position of the second limiting member corresponds to that of the first sensing member.
[0012] Furthermore, a second guide ring is provided on the side of the slider, and one side of the second connecting rod abuts against the outer peripheral surface of the second guide ring. When the second connecting rod moves, the slider is driven to slide on the vertical track through the second guide ring.
[0013] Furthermore, it also includes a third limiting block, which is disposed on the chassis body at the position corresponding to the second connecting rod. The end of the third limiting block near the second connecting rod is provided with an inclined surface, and the inclination angle of the inclined surface is adapted to the inclination angle of the second connecting rod in the preset motion trajectory.
[0014] Furthermore, the drive mechanism includes a motor, a reducer, and an eccentric wheel. The motor is connected to the reducer, the output end of the reducer is connected to the eccentric wheel, and the eccentric wheel abuts against the end of the stamping rod away from the worktable.
[0015] Furthermore, it also includes a first mold and a second mold. The first mold is set on the worktable to fix the position of the fastener. The second mold is set at one end of the stamping rod near the worktable and corresponds to the first mold. When the stamping rod moves down, the second mold cooperates with the first mold to complete the stamping and fastening operation of the fastener.
[0016] Compared with the prior art, this application has the following beneficial effects: This application provides a pressure-resistant button fastening device. A linkage mechanism moves a slider closer to the worktable, simultaneously causing a pressing rod to move downwards and trigger a second sensor. Subsequently, an elastic element recovers its deformation, pushing the pressing rod upwards to reset and trigger a first sensor. The linkage mechanism then again moves the pressing rod downwards, triggering the second sensor, thereby triggering a drive mechanism to drive the pressing rod to complete the precise pressing and fastening operation of the fastener on the worktable. This dual-sensor triggering mechanism ensures the accuracy and controllability of the pressing rod's movement. The fastening action is only initiated after the sensors are triggered in sequence, effectively preventing accidental injury when the operator's hand enters the pressing area and greatly improving the safety performance of the equipment.

[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 5A pressure-resistant button fastening device includes a workbench 1, on which a housing body 11 is mounted. A first sensor 12 and a second sensor 13 are mounted on the side of the housing body 11. A fastening mechanism 2 is located on the front of the housing body 11 and includes a stamping rod 21 and a slider 22. An elastic element 23 is fitted onto the outer surface of the stamping rod 21. The slider 22 is connected to the stamping rod 21, and a driving mechanism 5 is located at the end of the stamping rod 21 away from the workbench 1. A linkage mechanism 3 is located on the side of the housing body 11, with one side abutting against the slider 22. When the linkage mechanism 3 moves the slider 22 towards the workbench 1, it simultaneously moves the stamping rod 21 downwards, triggering the first sensor 12 and the second sensor 13. The driving mechanism 5 then drives the stamping rod 21 to perform a stamping and fastening operation on the fastener placed on the workbench 1.
[0025] In this embodiment, a chassis body 11 is provided on the workbench 1, and two sensors are provided on the side of the chassis body 11. The function of the sensors is to detect the movement state of the stamping rod 21 and determine whether the safety conditions for triggering the drive mechanism 5 are met, thereby ensuring that the stamping operation is only carried out under safe conditions. Specifically, the first sensor 12 and the second sensor 13 can be position sensors (such as photoelectric sensors or limit switches), which are used to monitor the position of the stamping rod 21 at different stages of movement to ensure that the equipment completes the necessary detection steps before performing the stamping action. The snapping mechanism 2 is provided on the front of the chassis body 11 and includes the stamping rod 21, the slider 22, the elastic element 23, and the drive mechanism 5. The stamping rod 21 is the component that directly performs the stamping action. The outer surface of the stamping rod is fitted with an elastic element 23 (such as a spring) for pushing the stamping rod 21 to reset after stamping and for buffering. The slider 22 is mechanically connected to the stamping rod 21 and plays the role of transmitting motion and force. The drive mechanism 5 (which can be a servo motor 51 or a similar power device) provides the necessary driving force to the stamping rod 21. The drive mechanism 5 is located at the end of the stamping rod 21 furthest from the worktable 1. Power is transmitted to the stamping rod 21 via mechanical transmission (such as a cam or crank), thereby driving it to complete the stamping and fixing operation of the fastener. The linkage mechanism 3 is located on the side of the main body 11, with one side abutting against the slider 22, forming a mechanical linkage. The function of the linkage mechanism 3 is to move the slider 22 closer to the worktable 1 via external operation (such as stepping on a foot pedal), thereby causing the stamping rod 21 to move downwards. The operator can swing the linkage mechanism 3 by stepping on the foot pedal, causing the sliding linkage to push the slider 22 downwards, thus causing the stamping rod 21 to move downwards synchronously. This converts the operator's input action into linear motion of the stamping rod 21, while the geometric design of the linkage mechanism 3 ensures the smoothness and reliability of the action. The anti-hand-striking principle of the equipment is specifically reflected in the process of the linkage mechanism 3 driving the slider 22 and the stamping rod 21 downwards, triggering the first sensor 12 and the second sensor 13. When the operator presses the foot pedal, the linkage mechanism 3 begins to move, causing the slider 22 and the stamping rod 21 to move downwards. The stamping rod 21 first reaches the position of the second sensor 13, triggering the second sensor 13 and sending a signal to the control system. After the stamping is completed, the elastic element 23 recovers its deformation, pushing the stamping rod 21 upwards to reset, until the slider 22 returns to its highest point and triggers the first sensor 12. Only when the slider 22 moves downwards again and triggers the second sensor 13 will the control system send a signal to start the drive mechanism 5 (such as the servo motor 51) to drive the cam to rotate, thereby driving the stamping rod 21 to complete the stamping and fixing operation of the fastener. The key to this design is that the drive mechanism 5 must be started through the sequential triggering of the first sensor 12 and the second sensor 13. If the stamping rod 21 does not return to its highest point to trigger the first sensor 12 (i.e., the reset action is not completed), even if the second sensor 13 is triggered, the drive mechanism 5 will not start, thus preventing the stamping rod 21 from performing the stamping action in an abnormal state.This dual-sensor triggering mechanism significantly improves the safety performance of the equipment.
[0026] Specifically, the operator first places the button on the workbench 1. The operator then presses the foot pedal for the first time, causing the linkage mechanism 3 to move, moving the slider 22 and the punching rod 21 downwards. The punching rod 21 first reaches the position of the second sensor 13. During this process, the punching rod 21 gradually approaches the fastener on the workbench 1 and first triggers the second sensor 13 located on the side of the main body 11. After detecting the position of the punching rod 21, the second sensor 13 sends a signal to the control system. The control system then controls the drive mechanism 5 to start, causing the cam to rotate and complete the buttoning work (i.e., the initial positioning and fixing of the button), but the complete punching operation is not performed at this time. Subsequently, the operator releases the foot pedal, and the elastic element 23 takes effect, pushing the punching rod 21 upwards to reset. When the punching rod 21 is fully reset, the slider 22 returns to its highest point and triggers the first sensor 12, the control system records this state, indicating that the equipment is ready for the next safe punching operation. At this point, the operator places the fabric in the corresponding position on the workbench 1. Since the fastening mechanism 2 will not perform the stamping action if the first sensor 12 is not triggered, it can greatly avoid accidental operation that could cause injury to the operator's hand. When the operator steps on the foot pedal again, the linkage mechanism 3 drives the slider 22 and the stamping rod 21 to move downwards again. The stamping rod 21 reaches the position of the second sensor 13 again, and the second sensor 13 sends a signal to the control system again. Since the first sensor 12 has been triggered and the stamping rod 21 has completed its reset, the control system determines that the safety conditions are met and then sends a signal to start the drive mechanism 5. The drive mechanism 5 drives the cam to rotate, which in turn drives the stamping rod 21 to perform a complete stamping and fastening operation on the fabric and fastener placed in the corresponding position on the workbench 1, firmly fixing the fastener to the fabric. This design effectively prevents hand injuries caused by operator error or equipment malfunction. For example, during equipment operation, if the operator accidentally steps on the foot pedal again before the stamping rod 21 has fully reset, the control system will not activate the drive mechanism 5 to perform the stamping because the first sensor 12 will not be triggered, thus preventing the stamping rod 21 from causing crushing injury to the operator's hand in an abnormal position. Similarly, if a malfunction occurs that prevents the stamping rod 21 from resetting properly, the first sensor 12 will also not be triggered, and the drive mechanism 5 will not start, ensuring the safety of the equipment in malfunction conditions.
[0027] In one embodiment, a foot pedal 4 is also included. The foot pedal 4 is connected to the linkage mechanism 3. The foot pedal 4 includes a foot pedal body 41 and a connecting component 42. The foot pedal body 41 is connected to the linkage mechanism 3 through the connecting component 42. Stepping on the foot pedal body 41 can drive the linkage mechanism 3 to move.
[0028] In this embodiment, the foot pedal 4 is the component for interaction between the operator and the device. The operator's stepping action drives the linkage mechanism 3, thereby initiating the entire buckling process. The foot pedal 4 includes a foot pedal body 41 and a connecting component 42. The foot pedal body 41 is the part directly stepped on by the operator, and the connecting component 42 connects the foot pedal body 41 to the linkage mechanism 3, ensuring that the stepping action is effectively transmitted to the linkage mechanism 3. This design allows the operator to control the device's operation with simple foot movements, conforming to ergonomics and improving operational convenience and efficiency. When the operator steps on the foot pedal 4, the force is transmitted to the linkage mechanism 3 through the connecting component 42, which in turn moves the slider 22 and the stamping rod 21 downwards, triggering the sensor and realizing the buckling operation.
[0029] In one embodiment, the linkage mechanism 3 includes a first link 31 and a second link 32, both of which are connected to the side of the chassis body 11 via a pivot 36; one end of the first link 31 is connected to the foot pedal 4, and the other end abuts against one end of the second link 32.
[0030] In this embodiment, the linkage mechanism 3 consists of a first link 31 and a second link 32. One end of the first link 31 is connected to the foot pedal 4, and the other end abuts against one end of the second link 32. This abutting relationship allows the stepping action of the foot pedal 4 to be transmitted to the second link 32 through the first link 31, thereby driving the movement of the entire linkage mechanism 3. The rotating shaft 36 is a component that connects the linkage mechanism 3 to the side of the chassis body 11, allowing the first link 31 and the second link 32 to rotate around the rotating shaft 36 when subjected to external force, thereby achieving the linkage effect of the linkage mechanism 3. When the operator steps on the foot pedal 4, the first link 31 is subjected to a downward force and rotates clockwise around the rotating shaft 36 (assuming the view is from the side of the chassis body 11), while its other end pushes one end of the second link 32 upward. Since the other end of the second link 32 abuts against the slider 22, the upward movement of the second link 32 will drive the slider 22 to move closer to the worktable 1, thereby linking the stamping rod 21 to move downward. The design of this linkage mechanism 3 cleverly utilizes the lever principle and mechanical linkage to convert the operator's foot movements into the linear movement of the stamping rod 21, achieving automation and safety in the buckling process. Simultaneously, the setting of the rotating shaft 36 ensures the stability and reliability of the linkage mechanism 3 during movement, reducing the risk of failure due to mechanical friction or loosening. The advantage of using two linkages is that they can effectively amplify and convert the input torque, achieving a larger stamping stroke and a more flexible movement path (a single linkage cannot simultaneously meet the requirements of long-distance transmission and angle adaptation). At the same time, the first limiting member 35 restricts the sliding range of the first guide ring 34, and the inclined surface of the third limiting block 37 adapts to the preset trajectory of the second linkage 32, ensuring precise control of the relative movement of the linkages, avoiding over-extension or jamming, and improving transmission stability and durability. Furthermore, the double-link structure facilitates a compact layout on the side of the main body 11, reducing the overall height, and, in conjunction with the reset mechanism 23, enhances safety against misoperation.
[0031] In one embodiment, the linkage mechanism 3 further includes an abutment plate 33. The first end of the abutment plate 33 is fixedly connected to the first connecting rod 31, and the second end of the abutment plate 33 is provided with a first guide ring 34. The first guide ring 34 is connected to the second end of the first connecting rod 31 through a rotating shaft 36. The first guide ring 34 is used to slide along the outer surface of the second connecting rod 32 when the first connecting rod 31 moves.
[0032] In this embodiment, the relative motion trajectory of the first link 31 and the second link 32 is guided by the sliding motion of the first guide ring 34, thereby improving the smoothness and accuracy of the linkage mechanism 3. When the operator presses the foot pedal 4, the first link 31 is subjected to force and moves. Through the action of the abutment plate 33 and the first guide ring 34, the second link 32 is pushed to move in a specific direction (upward), avoiding deviation or instability during the movement. The sliding contact between the first guide ring 34 and the outer surface of the second link 32 reduces frictional resistance, while the connection through the rotating shaft 36 ensures the flexibility of the structure. This structural design not only optimizes the motion efficiency of the linkage mechanism 3, but also reduces the risk of equipment failure due to mechanical deviation through the guiding effect.
[0033] In one embodiment, the linkage mechanism 3 further includes a first limiting member 35, which is disposed on the side of the second link 32 near the first link 31. The first limiting member 35 is used to block the first guide ring 34 when it slides along the outer surface of the second link 32 to a specific position, thereby limiting the relative range of motion of the first link 31 and the second link 32.
[0034] In this embodiment, the first limiting member 35 controls the range of motion of the linkage mechanism 3. When the first guide ring 34 slides along the outer surface of the second link 32 to a specific position, it is blocked by the first limiting member 35, thereby preventing the first link 31 and the second link 32 from continuing to move relative to each other. This design effectively prevents mechanical failures or damage caused by excessive extension or contraction of the linkage mechanism 3 during movement, improving the reliability and durability of the equipment. At the same time, the position of the first limiting member 35 can be adjusted according to actual needs to adapt to the fastening operation of fasteners of different sizes or shapes, further enhancing the flexibility and applicability of the equipment.
[0035] In one embodiment, the buckling mechanism 2 further includes a vertical track 24, which is disposed on the front of the chassis body 11, and the slider 22 slides on the vertical track 24; a second limiting member 25 is also disposed on the vertical track 24, which is used to limit the sliding stroke of the slider 22 on the vertical track 24, wherein the second limiting member 25 corresponds to the position of the first sensing member 12.
[0036] In this embodiment, the vertical track 24 provides a sliding path for the slider 22, ensuring stable vertical movement of the slider 22 during motion and preventing inaccurate stamping due to offset or wobbling. The second limiting member 25 restricts the sliding stroke of the slider 22. When the slider 22 slides to the position of the second limiting member 25, it is blocked and stops sliding down, protecting the equipment from excessive impact and ensuring that the stamping rod 21 accurately reaches the predetermined position before each stamping operation. Since the second limiting member 25 corresponds to the position of the first sensor 12, when the slider 22 triggers the second limiting member 25, it also approaches or has reached the detection range of the first sensor 12. This provides a reliable positioning basis for subsequent sensor triggering and drive mechanism 5 activation. Through the synergistic effect of the vertical track 24 and the second limiting member 25, the stamping accuracy and stability of the equipment are significantly improved, while also providing a safer and more reliable working environment for the operator.
[0037] In one embodiment, a second guide ring 26 is provided on the side of the slider 22, and one side of the second connecting rod 32 abuts against the outer peripheral surface of the second guide ring 26. When the second connecting rod 32 moves, the slider 22 is driven to slide on the vertical track 24 through the second guide ring 26.
[0038] In this embodiment, the second guide ring 26 optimizes the motion transmission efficiency between the slider 22 and the second connecting rod 32. When the second connecting rod 32 swings or moves linearly under the drive of the linkage mechanism 3, its side remains in contact with the outer peripheral surface of the second guide ring 26, driving the second guide ring 26 to move synchronously through friction or mechanical meshing. Since the second guide ring 26 is fixed to the side of the slider 22, this motion transmission is directly converted into the directional sliding of the slider 22 on the vertical track 24, ensuring the accuracy and stability of the pressing action of the stamping rod 21. The second guide ring 26 is made of a low-friction coefficient material, reducing energy loss during movement. At the same time, its outer peripheral surface is precision machined to maintain a high degree of compatibility with the contact surface of the second connecting rod 32, avoiding motion vibration caused by gaps or eccentricity. The design of the second guide ring 26 also considers wear resistance and impact resistance, enabling it to maintain structural integrity during long-term high-frequency use and further extending the service life of the equipment. With the cooperation of the second guide ring 26 and the vertical rail 24, the movement trajectory of the slider 22 is strictly limited within a predetermined range. Even under external force interference or equipment vibration, the vertical pressing action of the stamping rod 21 can be kept undeformed, thereby ensuring the forming quality and consistency of the fastener stamping.
[0039] In one embodiment, a third limiting block 37 is also included. The third limiting block 37 is disposed at the position of the chassis body 11 corresponding to the second connecting rod 32. The end of the third limiting block 37 near the second connecting rod 32 is provided with an inclined surface. The inclination angle of the inclined surface is adapted to the inclination angle of the second connecting rod 32 in a preset motion trajectory.
[0040] In this embodiment, the third limiting block 37 further optimizes the motion control of the linkage mechanism 3. Its inclined surface, designed near the end of the second link 32, matches the tilt angle of the second link 32 along its preset motion trajectory, allowing the second link 32 to smoothly contact the third limiting block 37 during movement. When the second link 32 moves to the position of the third limiting block 37 along the predetermined trajectory, the inclined surface design ensures a gradual transition in contact between the two, avoiding impact forces caused by sudden collisions, thereby reducing mechanical wear and noise. The third limiting block 37 ensures the accuracy and reliability of the overall motion of the linkage mechanism 3 by limiting excessive swinging or offset of the second link 32. This design improves the stability of the equipment during long-term operation and extends the service life of key components by reducing unnecessary mechanical stress. The position and inclined surface angle of the third limiting block 37 can be adjusted according to actual fastening requirements to adapt to the processing of fasteners of different sizes or shapes, further enhancing the flexibility and adaptability of the equipment.
[0041] In one embodiment, the drive mechanism 5 includes a motor 51, a reducer 52, and an eccentric wheel 53. The motor 51 is connected to the reducer 52, the output end of the reducer 52 is connected to the eccentric wheel 53, and the eccentric wheel 53 abuts against the end of the stamping rod 21 away from the worktable 1.
[0042] In this embodiment, the drive mechanism 5 achieves precise driving of the stamping rod 21 through a combination of a motor 51, a reducer 52, and an eccentric wheel 53. The motor 51, as the power source, converts electrical energy into mechanical energy, and the reducer 52 adjusts the speed and torque. The reducer 52 reduces the speed of the motor 51 through gear transmission while increasing the output torque, ensuring that the eccentric wheel 53 receives sufficient driving force. The eccentric design of the eccentric wheel 53 converts rotational motion into reciprocating linear motion of the stamping rod 21. When the eccentric wheel 53 rotates, its eccentric portion pushes the stamping rod 21 downwards, completing the stamping action; when the eccentric wheel 53 continues to rotate to the other side, the stamping rod 21 returns to its original position under the action of the elastic element 23. This design, through the conversion of mechanical structures, achieves efficient and stable movement of the stamping rod 21, while avoiding the impact and vibration that might result from direct drive by the motor 51. The eccentric wheel 53 can be made of high-strength alloy steel, and after precision machining and heat treatment, it can maintain dimensional stability and surface hardness under high load and high frequency working environment, thereby extending the service life of the drive mechanism 5. Through the coordinated work of the motor 51, reducer 52 and eccentric wheel 53, the drive mechanism 5 not only provides stable stamping power, but also ensures the safety and reliability of the stamping rod 21 during the movement process through mechanical limit and elastic reset mechanisms.
[0043] In one embodiment, the system further includes a first mold 14 and a second mold 15. The first mold 14 is disposed on the workbench 1 and is used to fix the position of the fastener. The second mold 15 is disposed at one end of the stamping rod 21 near the workbench 1 and corresponds to the first mold 14. When the stamping rod 21 moves down, the second mold 15 cooperates with the first mold 14 to complete the stamping and fastening operation of the fastener.
[0044] In this embodiment, the first mold 14 is fixed on the worktable 1, which can accurately position the fastener and prevent it from shifting or deflecting during the stamping process. The second mold 15 is installed at the lower end of the stamping rod 21, forming a vertically corresponding structure with the first mold 14. When the stamping rod 21 moves downward under the action of the drive mechanism 5, the second mold 15 approaches the first mold 14 and applies sufficient pressure at the moment of contact, so that the fastener is tightly bonded to the fabric. This mold matching method ensures the accuracy of stamping and avoids fastener deformation or fabric damage through uniform pressure distribution. The modular structure allows maintenance personnel to quickly replace worn mold parts, reducing equipment downtime and maintenance costs.
