Description

Technical Field

[0001] This utility model belongs to the field of zipper assembly, specifically relating to a riveting and testing mechanism for a linkage-type zipper assembly spring. Background Technology

[0002] Zippers, a common tool in clothing, are widely used in various garments. The spring-loaded zipper pull, with its self-locking function, prevents accidental slippage and is therefore very popular. To improve the production efficiency of spring-loaded zipper pulls, most zipper manufacturers have developed automatic spring assembly equipment. However, existing automatic spring assembly equipment typically checks the zipper pull for springs before riveting to prevent missing springs. But the springs in existing spring-loaded zipper pulls are usually small, light, and thin. When zipper pulls with unsecured springs operate across multiple stations, there is a risk of springs shifting or falling off.

[0003] In existing technologies, such as patent document CN118633809A, a zipper head assembly device and a zipper head assembly method are disclosed. The zipper head assembly device includes a workbench and a workstation turntable. An elasticity detection mechanism is set on the workbench, located between the spring pre-installation mechanism and the riveting mechanism. However, springs are usually small, light, and thin. Detecting the spring's condition before riveting it still carries the risk of spring displacement or falling off. Summary of the Invention

[0004] To address the problems in the existing technology, this utility model proposes a linkage-type zipper pull assembly spring clip riveting and detection mechanism. On the one hand, by placing the detection mechanism at the rear end of the riveting mechanism, it is used to detect whether the zipper pull after riveting is equipped with a spring clip, thereby improving the accuracy of spring clip detection and reducing the outflow of defective products. On the other hand, by using linkage, the riveting mechanism and the detection mechanism move synchronously, reducing the power source and lowering costs.

[0005] This invention is implemented as follows: a linkage-type zipper pull assembly spring clip riveting and detection mechanism includes a mounting plate, on which a transfer component for transporting the zipper pull is provided. A riveting component and a detection component are sequentially spaced along the transfer direction of the zipper pull. By placing the detection component at the rear end of the riveting component, the detection component directly detects whether there is a spring clip on the riveted zipper pull. Since the riveting component fixes the spring clip to the zipper pull, the spring clip will not shift during operation, thus improving the reliability of the detection component. Furthermore, the risk of spring clip displacement only exists in the process from spring clip loading to spring clip riveting. Compared to placing the detection component at the front end of the riveting component, placing the detection component at the rear end of the riveting component means that the spring clip only undergoes one transfer station from loading to riveting, while placing it at the front end involves two transfer stations: loading, detection, and riveting. Therefore, placing the detection component at the rear end of the riveting component further reduces the risk of spring clip displacement.

[0006] The riveting assembly and the detection assembly achieve synchronous up-and-down reciprocating motion through a shared power shaft; by driving the riveting assembly and the detection assembly simultaneously through the power shaft, an additional power source can be saved, reducing the manufacturing cost of the riveting assembly and the detection assembly.

[0007] A transmission module is mounted on the power shaft. The transmission module includes an eccentric wheel, a first connecting rod, and a second connecting rod. The eccentric wheel is pivotally connected to the power shaft and rotates synchronously with it. The first connecting rod is sleeved on the eccentric wheel and rotatably connected to it. When the eccentric wheel rotates, it drives the first connecting rod to reciprocate. One end of the second connecting rod is connected to the first connecting rod, and the other end is connected to the riveting assembly and the detection assembly. When the first connecting rod reciprocates, it drives the second connecting rod to move up and down. By simultaneously connecting the riveting assembly and the detection assembly with the second connecting rod, the riveting assembly and the detection assembly can move synchronously in a linked manner, reducing the power source and lowering costs.

[0008] Preferably, the riveting assembly further includes a support module. When the transfer assembly transports the pull head to the riveting assembly, the carrier carrying the pull head is located directly above the support module. When the riveting assembly rivets the pull head, the support module abuts against the carrier. Since the riveting unit applies significant pressure to the carrier during riveting, the support module balances the pressure exerted on the carrier by the riveting assembly, preventing damage to the carrier and improving its service life.

[0009] Specifically, the support module includes a mounting base installed on the mounting plate and a support unit that abuts against the vehicle. The mounting base has a limiting groove adapted to the support unit, and the support unit has a first adjusting groove, which is slidably connected to the limiting groove in a fixed manner. The first adjusting groove allows the support unit to be adjusted up and down, enabling it to adapt to vehicles of different sizes and improving the compatibility of the support module. The limiting groove restricts the freedom of the support unit, allowing it to slide only up and down, thus improving the convenience of adjustment.

[0010] Specifically, the riveting assembly includes a stamping head, which has a riveting groove and a clearance groove adapted to the slider. The bottom of the riveting groove is open, and its sides and top surfaces are rounded. When the sides and top surfaces of the riveting groove are rounded, the part of the slider being riveted also has a rounded transition, preventing sharp edges from appearing on the riveted part of the slider, thereby reducing the risk of injury from the slider and improving its safety.

[0011] Specifically, the stamping head is further provided with a second adjusting groove, which extends from the second connecting rod to the transfer assembly. The second adjusting groove is used to adjust the distance between the stamping head and the carrier, so that the riveting assembly can adapt to carriers and pull heads of different specifications, thereby improving the compatibility of the riveting assembly.

[0012] Preferably, the riveting assembly further includes a protective unit, which comprises a vertically arranged protective portion. When the carrier supporting the slider head is in place, the carrier approaches the protective portion. To improve the convenience of riveting the slider head, the part of the slider head to be riveted is usually inclined or arc-shaped. During the riveting process, there is a risk of slider head displacement. The protective unit is used to prevent the slider head from moving during riveting, thereby improving the reliability of the slider head riveting process.

[0013] Preferably, the mounting plate is further provided with a guide unit adapted to the second connecting rod, the guide unit being sleeved on the periphery of the second connecting rod. The guide unit is used to guide the second connecting rod during its up-and-down reciprocating motion, preventing changes in the movement trajectory of the second connecting rod and improving the reliability of the second connecting rod.

[0014] Specifically, the second connecting rod is prismatic in shape. When the second connecting rod is prismatic, the guide unit can restrict the rotation of the second connecting rod, thereby preventing the second connecting rod from rotating during its reciprocating motion and causing displacement of the riveting assembly and the detection assembly, thus improving the reliability of the second connecting rod. At the same time, by restricting the rotation of the second connecting rod through the guide unit, it is also possible to prevent the second connecting rod from generating torque on the first connecting rod, thereby preventing the first connecting rod from being subjected to torque and wearing, and improving the service life of the first connecting rod.

[0015] Preferably, the transfer assembly includes a divider, the output end of which is provided with a turntable. The power shaft is tractively connected to the input end of the divider, driving the turntable to rotate intermittently. The divider converts the continuous motion of the power shaft into the intermittent rotation of the turntable, ensuring that the carrier supporting the pull head is stationary when the riveting assembly and the detection assembly are working, thereby improving the convenience and reliability of the riveting assembly and the detection assembly.

[0016] Preferably, the detection component includes a sensing head, which is an infrared sensor or a proximity sensor. The detection end of the detection unit gradually decreases in size from top to bottom, forming a cone shape, and the radial dimension of the bottom of the detection end is adapted to the spring tab to prevent the pull head from causing false detections by the detection unit.

[0017] The beneficial effects of this utility model are:

[0018] This utility model proposes a riveting and detection assembly for a linked zipper pull assembly spring. On the one hand, by placing the detection assembly at the rear end of the riveting assembly, it is used to detect whether the zipper pull is equipped with a spring after riveting, thereby improving the accuracy of spring detection and reducing the outflow of defective products. On the other hand, by connecting the riveting assembly and the detection assembly simultaneously through the second connecting rod, the riveting assembly and the detection assembly can move synchronously in a linked manner, reducing the power source and lowering costs.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1-6 As shown, a riveting and detection mechanism for a linkage-type zipper pull assembly spring sheet includes a mounting plate 1. The mounting plate 1 is provided with a transfer assembly for transporting the zipper pull, and a riveting assembly and a detection assembly are arranged sequentially at intervals along the transfer direction of the zipper pull. By placing the detection assembly 4 at the rear end of the riveting assembly 3, the detection assembly 4 can directly detect whether there is a spring sheet on the riveted zipper pull. Since the riveting assembly 3 fixes the spring sheet to the zipper pull, the spring sheet will not be displaced during operation, thereby improving the reliability of the detection assembly 4. Furthermore, the risk of spring displacement exists only in the process from spring loading to spring riveting. Compared to placing the detection component 4 at the rear end of the riveting component 3, placing the detection component 4 at the rear end of the riveting component 3 means that the spring only goes through one station transfer from loading to riveting; while placing the detection component 4 at the front end of the riveting component 3 means that the spring goes through two stations transfer from loading to detection and then to riveting. Therefore, placing the detection component 4 at the rear end of the riveting component 3 further reduces the risk of spring displacement.

[0029] In this embodiment, the riveting assembly 3 further includes a support module 32. When the transfer assembly 2 transports the pull head to the riveting assembly 3, the carrier carrying the pull head is located directly above the support module 32. When the riveting assembly 3 rivets the pull head, the support module 32 abuts against the carrier. Since the riveting assembly 3 applies significant pressure to the carrier during riveting, the support module 32 balances the pressure exerted on the carrier during riveting, preventing damage to the carrier and improving its service life.

[0030] Specifically, the support module 32 includes a mounting base 321 mounted on the mounting plate 1 and a support unit 322 abutting against the carrier. The mounting base 321 is provided with a limiting groove 3211 adapted to the support unit 322. The support unit 322 is provided with a first adjustment groove 3212 and is slidably connected to the limiting groove 3211 in a fixed manner. The first adjustment groove 3212 allows the support unit 322 to be adjusted up and down, enabling the support unit 322 to adapt to carriers of different specifications and improving the compatibility of the support module 32. The limiting groove 3211 restricts the degree of freedom of the support unit 322, allowing the support unit 322 to slide only up and down, improving the convenience of adjustment of the support unit 322.

[0031] Specifically, the riveting assembly 3 includes a punch head 31, which has a riveting groove 311 and a clearance groove 312 adapted to the slider. The bottom of the riveting groove 311 is open, and its sides and top surfaces are rounded. When the sides and top surfaces of the riveting groove 311 are rounded, the part of the slider being riveted also has a rounded transition, preventing sharp edges from appearing on the riveted part of the slider, thereby reducing the risk of injury from the slider and improving its safety.

[0032] Specifically, the stamping head 31 is further provided with a second adjusting groove 313, which extends from the second connecting rod 63 to the transfer assembly 2. The second adjusting groove 313 is used to adjust the distance between the stamping head 31 and the carrier, so that the riveting assembly 3 can adapt to carriers and pull heads of different specifications, thereby improving the compatibility of the riveting assembly 3.

[0033] In this embodiment, the riveting assembly 3 further includes a protective unit 33, which includes a vertically arranged protective part 331. When the carrier carrying the slider head is in place, the carrier approaches the protective part 331. To improve the convenience of riveting the slider head, the part of the slider head to be riveted is usually inclined or arc-shaped. During the riveting process, there is a risk of slider head displacement. The protective unit 33 is used to prevent the slider head from moving during riveting, thereby improving the reliability of the slider head riveting.

[0034] In this embodiment, the detection component 4 includes a sensing head 41, which is an infrared sensor. The detection end of the sensing head 41 gradually decreases in size from top to bottom, forming a cone shape, and the radial dimension of the bottom of the sensing end is adapted to the spring sheet to prevent the pull head from causing false detection by the sensing head 41.

[0035] The riveting assembly 3 and the detection assembly 4 achieve synchronous up-and-down reciprocating motion through a shared power shaft 5. By driving the riveting assembly 3 and the detection assembly 4 simultaneously through the power shaft 5, an additional power source can be saved, reducing the manufacturing cost of the riveting assembly 3 and the detection assembly 4.

[0036] In this embodiment, the transfer assembly 2 includes a divider 21, the output end of which is provided with a turntable 22. The power shaft 5 is tractively connected to the input end of the divider 21, driving the turntable 22 to rotate intermittently. The divider 21 converts the continuous motion of the power shaft 5 into the intermittent rotation of the turntable 22, so that when the riveting assembly 3 and the detection assembly 4 are working, the carrier supporting the pull head is in a stationary state, improving the convenience and reliability of the riveting assembly 3 and the detection assembly 4.

[0037] A transmission module 6 is provided on the power shaft 5. The transmission module 6 includes an eccentric wheel 61, a first connecting rod 62, and a second connecting rod 63. The eccentric wheel 61 is connected to the power shaft 5 and rotates synchronously with it. The first connecting rod 62 is sleeved on the eccentric wheel 61 and rotatably connected to it. When the eccentric wheel 61 rotates, it drives the first connecting rod 63 to reciprocate. One end of the second connecting rod 63 is connected to the first connecting rod 62, and the other end is connected to the riveting assembly 3 and the detection assembly 4. When the first connecting rod 62 reciprocates, it drives the second connecting rod 63 to move up and down reciprocally. By connecting the riveting assembly 3 and the detection assembly 4 simultaneously through the second connecting rod 63, the riveting assembly 3 and the detection assembly 4 can move synchronously in a linked manner, reducing the power source and lowering costs.

[0038] In this embodiment, the mounting plate 1 is further provided with a guide unit 11 adapted to the second connecting rod 63. The guide unit 11 is sleeved on the periphery of the second connecting rod 63. The guide unit 11 is used to guide the second connecting rod 63 during its up-and-down reciprocating motion to prevent changes in the movement trajectory of the second connecting rod 63 and improve the reliability of the second connecting rod 63.

[0039] Specifically, the second connecting rod 63 is prismatic in shape. When the second connecting rod 63 is prismatic, the guide unit 11 can restrict the rotation of the second connecting rod 63, thereby preventing the second connecting rod 63 from rotating during its reciprocating motion, which would cause displacement of the riveting assembly 3 and the detection assembly 4, thus improving the reliability of the second connecting rod 63. At the same time, by restricting the rotation of the second connecting rod 63 through the guide unit 11, it is also possible to prevent the second connecting rod 63 from generating torque on the first connecting rod 62, thereby preventing the first connecting rod 62 from being worn due to torque and improving the service life of the first connecting rod 62.

[0040] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
