Description

Technical Field

[0001] The invention belongs to the technical field of button manufacturing, and in particular relates to a button punching and buttoning device. Background Art

[0002] The button-setting machine is used to press and rivet the male / female buttons and the face buttons of the snap fastener together by external force, so that the male / female buttons and the face buttons are tightly fixed on the stored fabric. For higher process requirements, a pre-punching process is required.

[0003] In the related art, the buckle punching machine is powered by a motor plus a flywheel energy storage. On the one hand, the power system of the motor plus the flywheel is relatively slow in response speed and cannot be started and stopped frequently. When the punching step is added, the equipment needs to handle more processes. This slow response characteristic will further delay the overall production rhythm and further reduce production efficiency. On the other hand, the inertia of the flywheel system makes it difficult to stop quickly when the power needs to be stopped. When the punching step is added, the equipment needs to frequently switch between punching and buckling. If the power cannot be stopped in time, the mold may be subjected to unnecessary impact or pressure, thereby increasing the risk of damage to the buckle. Summary of the invention

[0018] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but are not to be construed as limiting the present invention. All other embodiments obtained by ordinary technicians in the field without creative work based on the embodiments of the present invention are within the scope of protection of the present invention.

[0020] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0021] Please refer to Figures 1 to 7 The present invention provides a button punching device 100, comprising a first layer structure 11 and a second layer structure 12, wherein the first layer structure 11 and the second layer structure 12 have a movement direction of approaching or moving away from each other; wherein the first layer structure 11 comprises a button punching member 111 and a punching member 112; the second layer structure 12 comprises a button punching seat 121 matched with the button punching member 111, a punching seat 122 matched with the punching member 112, and a movable connecting rod 123, wherein the movable connecting rod 123 is rotatably connected with the punching seat 122, and the movable connecting rod 123 drives the punching seat 122 to have a movement direction of approaching or moving away from the button punching seat 121; When the movable connecting rod 123 drives the punching seat 122 away from the fastening seat 121, the fastening seat 121 is exposed on the movement trajectory of the fastening member 111. When the movable connecting rod 123 drives the punching seat 122 close to the fastening seat, the punching seat 122 is located on the movement trajectory of the punching member 112 and blocks the fastening seat 121.

[0022] The design of the moving direction of the first layer structure 11 and the second layer structure 12 towards or away from each other enables the fastener 111 and the hole punching member 112 to coordinately complete the hole punching and button punching operations in the same device. Through the cooperation of the hole punching seat 122 and the button punching seat 121, and the connection of the moving connecting rod 123, this structure allows the device to complete complex processes without frequent position changes, thereby shortening the processing time and improving production efficiency.

[0023] By rotating the mobile connecting rod 123 and the punching seat 122, the punching seat 122 can be close to or away from the buckle seat 121. This design simplifies the operation, avoids the trouble of manually adjusting or repositioning the workpiece in traditional equipment, reduces positioning errors, and reduces the labor intensity of operators.

[0024] Specifically, the movable connecting rod 123 includes two first sections 1231, two second sections 1232 and a shielding portion 1233. The two ends of the shielding portion 1233 are respectively connected to the two second sections 1232. A punching seat 122 is installed on the shielding portion 1233. Each second section 1232 is rotatably connected to a first section 1231.

[0025] The two-stage structural design (two first sections 1231, two second sections 1232) and the connection of the shielding portion 1233 ensure that the flipping movement of the moving link 123 is more stable. This design can effectively avoid shaking or inaccurate positioning caused by a single link structure, and ensure that the punching seat 122 stably and accurately approaches or moves away from the buckle seat 121 during the flipping process.

[0026] The design of the rotation connection between each second section 1232 and a first section 1231 allows the movable connecting rod 123 to operate flexibly, helping the punching seat 122 to move between different positions more easily. This flexibility simplifies the operation, and the operator does not need to make frequent manual adjustments, but relies on the flipping of the connecting rod to automatically complete the process switching between punching and buckling.

[0027] The shielding part 1233, as a structure connecting the two second sections 1232, not only improves the rigidity and stability of the overall structure, but also makes the punching process more precise through the punching seat 122 installed thereon, reducing the offset or misalignment problem of the workpiece. Since the punching seat 122 is installed on the shielding part 1233, it means that the punching seat 122 can be integrated into the structure of the moving connecting rod 123, avoiding additional complex mechanical devices. The entire punching seat 122 and the moving connecting rod 123 have a compact structure and high integration, making the overall size of the equipment more compact and saving the space layout requirements of industrial equipment.

[0028] In another embodiment, a punching seat 122 is provided on the movable connecting rod 123, and the movable connecting rod 123 is slidably connected with the punching seat 121. Two relative slide rails are provided on the peripheral side of the punching seat 121, and the movable connecting rod 123 is assembled on the two slide rails. When the movable connecting rod 123 slides close to the punching seat 121, the punching seat 121 is aligned with the punching seat 122, and the punching seat 122 blocks the punching seat 121, and the punching member 112 can be used in conjunction with the punching seat 122; when the movable connecting rod 123 slides away from the punching seat 121, the punching seat 121 is separated from the punching seat 122, and the punching seat 122 is exposed, and the punching member 111 can be used in conjunction with the punching seat 121.

[0029] Please refer to Figure 3 and Figure 4 Furthermore, each first section 1231 is provided with a movable hole 1234 , and two bosses 1211 are protruded from both sides of the buckle seat 121 , and each boss 1211 is plugged into each movable hole 1234 in a one-to-one correspondence, and the boss 1211 has a movement direction along the extension direction of the movable hole 1234 .

[0030] The cooperation between the movable hole 1234 and the boss 1211 enables the punching seat 121 to move along a predetermined track during the movement without being restricted to a fixed path. The boss 1211 can slide in the movable hole 1234, which allows the punching seat 121 to adjust its position as needed to ensure the accuracy of the punching and punching operations. This design increases the flexibility of the equipment and adapts to different processing requirements.

[0031] The plugging of the movable hole 1234 and the boss 1211 increases the firmness of the structure. When the machine is working, the cooperation of the boss 1211 and the movable hole 1234 can withstand greater mechanical stress, avoiding the dislocation or damage of components caused by vibration or impact. This not only improves the stability of the equipment, but also extends the service life of the equipment.

[0032] Since the boss 1211 can move in the movable hole 1234, it is convenient for the maintenance and adjustment of the device. When the device needs to be calibrated or adjusted, the operator can fine-tune the device by controlling the position of the boss 1211, without replacing complex parts, simplifying the maintenance process.

[0033] The projection 1211 moves along the direction of the movable hole 1234, which can ensure that the button punching seat 121 can achieve accurate movement towards or away from each other between different operation stages (punching and button punching). This movement mode allows the button punching seat 121 and the hole punching seat 122 to switch with each other according to the process requirements, ensuring that each step of the operation can be smoothly connected and reducing unnecessary intermediate steps.

[0034] Please refer to Figure 2 In one embodiment of the present invention, the button punching device 100 also includes a protective structure 13, which includes an anti-beater safety cylinder 131 and an anti-beater trigger rod 132 transmission-connected to the anti-beater safety cylinder 131, the anti-beater safety cylinder 131 is used to drive the anti-beater trigger rod 132 to move closer to or away from the second layer structure 12, and the end of the anti-beater trigger rod 132 away from the anti-beater safety cylinder 131 is provided with a protective hole 133 smaller than the diameter of the button punching piece 111 or the punching piece 112.

[0035] The protection structure 13 is provided with a sensor between the first structure 11 and the second structure 12, which can automatically detect the presence of foreign objects or hands in the buckle or hole punching operation area. Once the hand or foreign object approaches the second structure 12 (i.e. the buckle punching seat 121 or the hole punching seat 122), the anti-hand-beating trigger rod 132 will detect and promptly stop the power output of the equipment, thereby effectively preventing the operator from being injured during the operation of the equipment, especially when the buckle punching member 111 or the hole punching member 112 is in motion.

[0036] The design diameter of the protection hole 133 is smaller than the diameter of the fastener 111 or the punch 112, so that the fastener 111 or the punch 112 cannot pass through, and when the movement of the anti-beater trigger rod 132 is triggered, the system will turn off the drive motor of the fastener 111 or the punch 112.

[0037] Driven by the anti-beater safety cylinder 131, the anti-beater trigger rod 132 can be continuously detected during the entire operation process. Real-time movement direction control ensures that the trigger rod can approach or move away from the second layer structure 12 at the appropriate time, achieving continuous safety monitoring. This not only improves the degree of automation, but also significantly improves the safety of the equipment, especially in high-frequency and high-speed working environments.

[0038] In addition to protecting the operator, the detection of the anti-beater trigger rod 132 can also prevent damage to the equipment due to tools or other objects accidentally entering the working area. When a foreign object enters the protection hole 133, the equipment will stop immediately to prevent unnecessary damage to the fastener 111 or the punch 112, thereby extending the service life of the equipment.

[0039] This design will not excessively interfere with the punching or buttoning operation. Although the trigger lever has a keen detection ability for foreign objects and hands, it ensures that the stop function is triggered only when necessary through the design of the protection hole 133, thereby avoiding unnecessary work interruptions and improving the balance between the work efficiency and safety of the equipment.

[0040] Please refer to Figure 6 In this embodiment, the first layer structure 11 is provided with two installation holes spaced apart from each other, and the fasteners 111 and the punching members 112 are respectively installed in the two installation holes, and the fasteners 111 and the fasteners 111 are both provided with elastic members 113 abutting against the periphery of the installation holes.

[0041] The setting of the elastic member 113 can play a buffering role when the fastener 111 and the punching member 112 are working. When the fastener 111 and the punching member 112 perform high-frequency punching or fastening operations, the elastic member 113 can absorb part of the impact force generated, reduce the wear of the equipment and the mold, and extend the service life of the equipment.

[0042] Since the elastic member 113 can exert a certain restoring force on the fastener member 111 and the punching member 112, they can quickly return to their original positions after being impacted, thereby ensuring that the fastener member 111 and the punching member 112 are always in the correct working position. This plays an important role in ensuring the accuracy of each punching or fastening operation.

[0043] Vibrations may occur during the punching and buttoning operations, especially during high-speed operation. The presence of the elastic member 113 can effectively reduce the impact of these vibrations on the equipment structure and enhance the stability of the working process. This can not only ensure the accuracy of the equipment, but also reduce the impact of vibrations on the surrounding environment and operators.

[0044] The buffering effect of the elastic member 113 can also reduce the metal collision sound generated by the fastener 111 and the punching member 112 during operation, effectively reduce the noise during equipment operation, and improve the comfort of the working environment, which is particularly important for protecting the operator during long-term continuous operation.

[0045] The elastic member 113 can disperse the stress during the operation of the equipment, reduce the direct wear of key components, and avoid fatigue damage caused by long-term high-intensity operation. This prolongs the maintenance cycle of the equipment, reduces the frequency of failures, and further improves the reliability and durability of the equipment.

[0046] Please refer to Figure 5 In this embodiment, the button punching device 100 also includes a first feeding component 14 and a second feeding component 15. The first feeding component 14 includes a first input port 141, a first material bin 142 and a first track 143. The first material bin 142 is equipped with male / female buckles, and the first track 143 is connected to the first layer structure 11. The second feeding component 15 includes a second input port 151, a second material bin 152 and a second track 153. The second material bin 152 is equipped with surface buckles, and the second track 153 is connected to the second layer structure 12.

[0047] The face button is first delivered to the designated buttoning seat 121 by the feeding assembly. Since the face button is located outside the button, it is usually the first to be fixed on the cloth. The installation of the face button is to place the face button into the buttoning bottom mold and fix it on the cloth to form the basic appearance part.

[0048] After the face buckle is installed, the male buckle and the female buckle are transported to the punching or buckling position through another feeding assembly. According to the design, a part of the male buckle or the female buckle will be mechanically buckled with the face buckle. This process can be completed by a buckling machine, and the male buckle and the female buckle are respectively combined with the face buckle through the buckling action to form a complete buckling structure.

[0049] If it is necessary to punch holes in the fabric first, the punching member 112 will be performed before installing the male buckle and the female buckle to ensure that the buckle can penetrate the fabric and be firmly connected to the surface buckle. Punching holes is to allow the male buckle or the female buckle to better embed into the fabric and improve the stability of installation.

[0050] The first feeding assembly 14 is responsible for conveying male / female buckles, and the second feeding assembly 15 is responsible for conveying face buckles. This separate feeding system can ensure that male / female buckles and face buckles are independently and orderly conveyed to their respective workstations during the production process. This can effectively prevent different types of fasteners from mixing or colliding during the conveying process, and ensure that each fastener accurately enters its corresponding installation position.

[0051] The two independent feeding assemblies are connected to the first layer structure 11 and the second layer structure 12 through rails, which means that the equipment can handle the conveying and installation operations of male / female buckles and face buckles at the same time. This can reduce the steps of frequently changing workpieces in the traditional single feeding system, greatly shorten the production cycle, improve production efficiency, and avoid repeated positioning and corresponding time waste.

[0052] Each feeding assembly is equipped with an independent track to guide the male / female buckle and face buckle to the correct working position. This design helps to improve positioning accuracy, ensuring that each fastener can accurately reach the punching or buckling position, ensuring the quality and consistency of installation.

[0053] The design of the automatic feeding component reduces the need for manual intervention and the risk of errors in manual operation. The independent feeding system enables the equipment to maintain high stability at high speeds, reduces downtime or failures caused by improper workpiece delivery, and further improves the automation of the equipment.

[0054] This independent feeding system design allows the equipment to adapt to a variety of specifications and types of fasteners, and male / female buckles and face buckles can be adjusted or replaced according to production needs. In practical applications, this flexibility can meet the personalized needs of different production lines or different batches of products, further enhancing the adaptability of the equipment.

[0055] Specifically, a feeding connecting rod is provided in the first material bin 142 and the second material bin 152. The swing connecting rod includes a swing rod, a transmission rod, a slider and a feeding cylinder connected in sequence. The swing rod is arranged in the first material bin 142 or the second material bin 152. The slider is provided with a cam bearing connected to the connecting rod. The feeding cylinder is used to drive the slider to move in a straight line.

[0056] The design of the cam bearing can efficiently convert the rotary motion of the feed cylinder into the linear motion of the slider. This conversion reduces power loss, enables the equipment to more accurately control the motion trajectory of the feed, and improves the feeding efficiency and accuracy. The slider is driven by the feed cylinder to move in a straight line, and the slider drives the connecting rod system to achieve precise feeding operation.

[0057] The setting of the cam bearing can effectively reduce the friction between the connecting rod and the slider, making the power transmission more stable. This design not only reduces the energy consumption of the equipment during operation, but also reduces equipment failures caused by wear, further improving the service life and reliability of the entire device.

[0058] The connection between the swing rod and the transmission rod, combined with the linear motion of the slider and the feeding cylinder, ensures that the feeding action is flexible and controllable. Driven by the feeding cylinder, the feeding speed and frequency can be flexibly adjusted according to actual needs to meet the production needs of different types and specifications of fasteners. This flexibility helps to improve production efficiency, especially when batching different fasteners, the feeding action can be adjusted according to product characteristics.

[0059] Specifically, the first layer structure 11 is provided with a male / female buckle positioning hole 171 and a male / female buckle positioning push rod 172, the second layer structure 12 is provided with a face buckle positioning hole 161 and a face buckle positioning push rod 162, the movement trajectory of the male / female buckle positioning push rod 172 is set between the first track 143 and the male / female buckle positioning hole 171, and the movement trajectory of the face buckle positioning push rod 162 is set between the second track 153 and the face buckle positioning hole 161.

[0060] The movement trajectory of the male / female buckle positioning push rod 172 and the face buckle positioning push rod 162 accurately controls the movement of the fastener from the track to the positioning hole. This ensures that the male / female buckle and the face buckle can accurately enter their corresponding positioning holes, avoiding the fastener from being offset or misaligned during the conveying process. This precise positioning improves the accuracy of subsequent buckling and punching operations.

[0061] This automated push rod design reduces manual intervention and ensures accurate positioning of male / female buckles and face buckles, thereby improving production efficiency. Through precise push rod movement, fasteners can be automatically sent to the working position for buckling and drilling, ensuring the consistency and stability of the production process.

[0062] The motion trajectory of the push rod is strictly controlled, ensuring that the fastener will not get stuck, misaligned or stagnant during the transportation process from the track to the positioning hole. This design avoids the accumulation or deviation of workpieces, reduces downtime in the production process, and reduces the possibility of equipment failure.

[0063] Please refer to Figure 7 In this embodiment, the button punching device 100 also includes an impact component 18, which includes a power assembly 181 and a pressure block 182 that is transmission-connected to the power assembly 181, and the pressure block 182 is provided with an impact position 1821 having the same cross-sectional area as the button punching member 111 or the punching member 112, and the hardness of the impact position 1821 is greater than the hardness of the peripheral area.

[0064] The hardness of the impact position 1821 is greater than that of the peripheral area, which means that during the buckling or punching operation, the impact position 1821 can provide sufficient rigidity and strength to make the punching or buckling process more precise. Through this differentiated hardness design, the buckling member 111 or the punching member 112 can be more evenly stressed during the processing, thereby ensuring the quality and appearance consistency of each buckle.

[0065] The design of the impact part 1821 having a harder surface than the peripheral area ensures that the part most susceptible to wear during the impact process has a stronger wear resistance. This can reduce the frequency of wear of the impact component 18 in long-term use, extend the service life of the equipment, and reduce the cost of repair and replacement of parts.

[0066] Since the hardness of the impact position 1821 is higher than that of the peripheral area, the impact force during the punching or drilling operation is concentrated on the impact position 1821 instead of being spread to the surrounding area. This reduces damage to the workpiece and other parts of the equipment and effectively prevents the workpiece from being deformed, cracked or otherwise damaged under high-intensity impact force.

[0067] Furthermore, the power assembly 181 includes a power servo motor 1811, a reducer 1812, an eccentric wheel 1813 and a power shaft 1814 which are sequentially connected in transmission. The power shaft 1814 is fixedly connected to the pressure block 182, and the eccentric wheel 1813 is used to change the rotation direction of the power servo motor 1811 into a linear direction.

[0068] The design of the eccentric wheel 1813 converts the rotary motion of the power servo motor 1811 into linear motion. This design ensures that the rotary power can be efficiently transmitted to the power shaft 1814 and drives the pressing block 182 to perform the buckling or punching operation. This power conversion reduces the power loss in the middle, ensures the efficient use of power, and enables the equipment to maintain stable operation under high load.

[0069] The use of the power servo motor 1811 greatly improves the motion accuracy of the entire power assembly 181. The power servo motor 1811 has programmable and high-precision control capabilities, and can accurately adjust the motion speed and force of the pressing block 182 as needed. Through this precise control, the buckling or punching operation can be more flexibly adapted to fasteners of different types and sizes, improving the accuracy and consistency of processing.

[0070] The addition of the reducer 1812 ensures that the high speed of the power servo motor 1811 can be converted into a low-speed, high-torque motion suitable for buttoning and punching operations. This not only improves the effective use of power, but also ensures the stability and durability of the equipment in high-load production. In this way, the equipment can complete more processing operations in a shorter time, thereby improving overall production efficiency.

[0071] The eccentric wheel 1813 converts the rotational motion into the linear motion. Through the smooth transition of the eccentric wheel 1813, the impact force in the power transmission process is effectively buffered, reducing the vibration and instability of the mechanical system. The fixed connection between the power shaft 1814 and the pressing block 182 also ensures the smooth power output during the punching and buttoning operations, reducing the damage to the workpiece and the wear of the equipment.

[0072] The combination of the power servo motor 1811 and the reducer 1812 can flexibly adjust the output power according to actual needs, avoiding the energy waste caused by frequent start and stop in traditional systems. The high efficiency and energy saving characteristics of the servo motor help reduce energy consumption in the production process and improve the economy of the equipment.

[0073] The power servo motor 1811 can adapt to different buckling and punching requirements, such as different fastener specifications and materials, through precise control. With the design of the reducer 1812 and the eccentric wheel 1813, the power shaft 1814 can quickly respond and adjust its motion trajectory and strength according to the workpiece requirements, so that the equipment can flexibly respond to diverse production tasks.

[0074] Furthermore, the power assembly 181 also includes a male / female buckle material taking cylinder 183, which is synchronously driven with the power servo motor 1811. The synchronous drive of the male / female buckle material taking cylinder 183 and the power servo motor 1811 ensures that before each buckle or hole punching operation, the male / female buckle can be accurately and timely taken out of the silo and transported to the buckle punching position. The synchronous drive design avoids the time misalignment between material taking and buckle punching, thereby making the entire production process smoother and continuous, reducing unnecessary waiting time, and significantly improving production efficiency.

[0075] Since the power servo motor 1811 and the male / female fastener picking cylinder 183 are driven synchronously, the picking and fastening actions are highly consistent, ensuring that each fastener can be accurately positioned and fastened at the right time. This avoids the possible problems of fastener misalignment, missed fastening or repeated operations, thereby improving the accuracy of the production process and the quality consistency of the product.

[0076] The button punching device 100 further includes a foot-operated start switch 19 , which is used to control the start and stop of the power assembly 181 .

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
