Description

Technical Field

[0001] This invention relates to the technical field of zipper manufacturing, and more particularly to a butterfly-shaped top stop feeding mechanism and top stop machine. Background Technology

[0002] The top stop of a zipper is a stop fixed to the top of the zipper and the two teeth on the left and right sides. Its main function is to prevent the zipper pull from slipping off the top of the chain when it is pulled or closed, and to ensure that the zipper stays in the correct position when closed.

[0003] Currently, there is a butterfly-shaped top stop, which includes a butterfly-shaped body and a buckle set on the body. The body and buckle are integrally formed and are generally made of metal (e.g., copper butterfly buckle). Its shape resembles butterfly wings and can disperse stress through its wing-like structure, making it more resistant to impact and repeated bending. At the same time, the metal material gives it excellent strength and toughness, which has led to its good application in the zipper manufacturing field.

[0004] The top stop machine is used to install butterfly-shaped top stops onto the zipper tape. For example, the utility model with authorized publication number CN223195629U relates to a metal butterfly-shaped movable top stop machine, which includes a frame, a feeding mechanism, and an installation mechanism. The feeding mechanism is used to arrange the scattered top stops and transport them one by one to the installation mechanism. The installation mechanism is used to install the top stops onto the zipper tape. The installation mechanism includes a tape pressing assembly and an assembly assembly. The tape pressing assembly is used to drive the zipper tape into a Y shape. The assembly assembly includes a positioning plate set on the mounting frame and a mold base slidably set on the positioning plate. The mold base is slidably fitted with the positioning plate. The mounting frame is also provided with a drive seat. An elastic element is provided at the opening of the positioning plate. The elastic element connects the positioning plate and the mold base. The mold base is integrally formed with a mold block. The shape of the mold block is adapted to the shape of the top stop. The elastic element causes the mold block to abut against the end outlet of the feeding mechanism. In use, the feeding mechanism arranges the scattered top stops and transports the end top stops to the mold block for support. At the same time, the pressing assembly drives the zipper tape into a Y shape. The driving mold base extends into the positioning plate, and the elastic element is compressed, aligning the top stops on the mold block with the branch of the Y-shape of the zipper tape, with the top stops positioned above the branch of the Y-shape. Then, by pressing down on the top stops, they are detached from the mold block. During this process, the elastic element is further compressed, and the buckle of the top stops passes through the fabric tape and locks with the outer lower mold, completing the installation.

[0005] However, the butterfly-shaped top stop is a tiny, irregularly shaped component, characterized by its light weight, susceptibility to wobbling, and tendency to shift. Current feeding processes rely solely on conventional vibration feeding and simple guidance. However, due to its unique shape and small size, this arrangement easily leads to jamming or stacking of multiple top stops, causing production interruptions. Furthermore, the telescopic mold base is prone to wobbling during movement, ultimately resulting in unstable feeding positions and affecting assembly accuracy and reliability.

[0006] Therefore, the existing butterfly-shaped top stop machine still requires manual supervision to ensure operation, and can only achieve semi-automatic operation as a whole, and the degree of automation needs to be improved. Summary of the Invention

[0007] To address the issue that existing systems still require manual supervision to ensure operation and can only achieve semi-automatic operation, this invention provides a fully automatic, high-precision, and high-yield butterfly-shaped top-stop feeding mechanism and top-stop machine.

[0008] The first objective of this invention is to provide a butterfly-shaped top-stop feeding mechanism, which adopts the following technical solution: A butterfly-shaped top stop feeding mechanism includes a material handling component, a transport track, a material control component, a material conveying component, and a positioning seat. The material handling component is used to handle the material, arranging the top stops in a desired posture in an orderly sequence and outputting them to the transport track. The transport track forms a conveying channel for the top stops to pass through, and a guide block is provided on the transport track to restrict the posture of the top stops in the conveying channel. The conveying channel forms a discharge position that is just enough for a single top stop to be removed. The positioning seat forms a positioning slot that engages with the top stop, and the material conveying component is used to transfer the top stop at the discharge position to the positioning seat. The material control assembly includes a material control chute connected to the discharge position and a clamping block slidably disposed in the material control chute; the clamping block includes an integrally formed support part and a connecting part, the support part always supports the upper stop of the discharge position within the sliding stroke of the clamping block, and the side wall shape of the discharge position is adapted to the upper stop; the support part is provided with a limit strip, and each limit strip is formed with a correction part, which is used to correct the posture of the upper stop of the discharge position.

[0009] By adopting the above technical solution, during feeding, the upper stops are arranged in the required posture in an orderly manner and output to the transport track. The guide block ensures that the conveying channel is only for the upper stops to pass through in the required posture, thereby eliminating upper stops with abnormal posture and effectively avoiding material jamming, stacking, or workstation docking deviation caused by disordered upper stop posture.

[0010] Next, the clamping block is driven to slide along the material control chute, causing the limiting strip to extend out of the discharge position, allowing the top stop closest to the discharge position in the conveying channel to enter the discharge position. Then, the clamping block is driven again, causing the limiting strip to extend into the discharge position. The correction unit abuts against and drives the front wing of the main body, pushing the top stop of the discharge position against the wall of the conveying channel, thus achieving position correction. The correction unit effectively solves the problems of the top stop being lightweight, prone to shaking, easy to deviate, and having difficulty in accurately controlling its posture. Through precise fitting and abutment correction, it avoids positioning failure due to small size. At the same time, it can reduce the gap error between the top stop and the channel, ensuring uniform posture and consistent position when multiple top stops are continuously feeding, and significantly reducing the impact of small deviations on the accuracy of subsequent installation. The material conveying component removes the top stop from the discharge position. Simultaneously, the driving clamping block slides along the material control chute, allowing the limit strip to fully extend into the discharge position. This blocks and isolates subsequent top stops waiting to be discharged within the conveying channel, preventing them from rushing into the discharge position and interfering with the material handling process during the material handling moment, thus ensuring a smooth and uninterrupted material handling process. Finally, the material conveying component transfers the top stop to the positioning slot, completing the loading of the top stop.

[0011] Through the structural design of the clamping block and limiting strip, a single drive source enables multiple positioning functions, including entry and release, posture correction, and material handling and blocking. While simplifying the overall structure, this design makes the connection between each process step more compact and reliable. The correction unit matches the shape of the upper stop's front wing, and the two correction units create a positioning trend that drives the upper stop towards the center, further ensuring the upper stop's posture is centered and corrected, eliminating lateral movement margins, and ensuring the upper stop is always in the preset reference position within the discharge position. This effectively improves positioning consistency and repeatability accuracy, providing a more stable and reliable upper stop state for subsequent gripping and assembly processes. It effectively solves the problems of positioning deviation and motion interference that easily occur during the feeding process of butterfly-shaped upper stops. The overall technical solution is ingeniously conceived and highly integrated.

[0012] It solves the problems of material jamming, stacking, production interruption and low assembly accuracy caused by the butterfly-shaped upper stop being light, easy to shake, easy to deviate and improper posture arrangement. It effectively eliminates the accumulation of small deviations and material picking interference, eliminates the need for manual assistance and supervision, and greatly improves the upper stop feeding positioning accuracy and assembly reliability. It realizes the leap from semi-manual intervention to fully automatic, high-precision and high-stability feeding, and significantly improves assembly reliability and operation efficiency.

[0013] Preferably, the transport track is provided with a detection element for detecting whether the discharge position has an upper stop and an indicator element for indicating whether there is an upper stop, and the indicator element is electrically connected to the detection element.

[0014] By adopting the above technical solution, during the detection process, if there is no upper stop at the discharge position, the indicator status changes to indicate that the discharge position does not have an upper stop, and the material conveying component is prohibited from working; if there is an upper stop at the discharge position, the indicator status changes to indicate that the discharge position has an upper stop, and the material conveying component proceeds to the next step. This effectively avoids malfunctions such as empty picking and empty feeding, prevents equipment from running idle or interfering, ensures stable and reliable connection between upper stop feeding and subsequent processes, and improves the continuity and safety of the entire machine operation.

[0015] Preferably, the material handling assembly includes a Z-axis sliding section, an X-axis sliding section, a Y-axis sliding section, and a gripping component.

[0016] By adopting the above technical solution, the X-axis sliding part, Y-axis sliding part, and Z-axis sliding part work together to allow the gripper to remove the material from the discharge position and transfer it to the positioning slot. The Z-axis sliding part, X-axis sliding part, and Y-axis sliding part enable the gripper to move in three axes, ensuring the flexibility of the gripper's movement.

[0017] Preferably, the gripper is a rotary pneumatic gripper, vacuum suction cup, vacuum nozzle, or other type of pneumatic gripper.

[0018] By adopting the above technical solution, suitable gripping components can be flexibly selected according to the material and assembly posture requirements of the upper stop.

[0019] Preferably, the gripper is a rotary pneumatic gripper; the transport track is also provided with a clearance groove, the clearance groove is for the gripper to clamp inside, and the clearance groove is connected to the discharge position; the support part forms a clearance area, the clearance area is connected to the clearance groove; the bottom of the positioning slot is also provided with a relief groove, the relief groove is used to provide clearance space for the opening action of the gripper.

[0020] By adopting the above technical solution, when the gripper is a rotating pneumatic gripper, collisions between the gripper and the gripper during the internal clamping process are avoided, making the upward transfer process smoother.

[0021] The second objective of this invention is to provide an upper stop mechanism, which adopts the following technical solution: An upper stop mechanism includes a feeding mechanism as described in any of the above, and further includes an installation mechanism and a belt pulling mechanism; the installation mechanism is used to install the upper stop in the positioning slot onto the zipper belt; the belt pulling mechanism is used to drive the zipper belt forward, advancing by the length of one zipper segment each time.

[0022] By adopting the above technical solutions, the various mechanisms work together to achieve fully automated operation of the entire process of loading, transferring, positioning and assembly, thereby improving production efficiency.

[0023] Preferably, the installation mechanism includes a pressing assembly and an assembly assembly; the pressing assembly includes a lower mold base, a guide plate, a forming base, and a forked stop slidably disposed on the forming base; the guide plate and the forming base are distributed sequentially along the forward direction of the zipper belt, the guide plate has a zipper belt groove for sliding, and the forked stop can extend and retract on the forming base; two sets of pusher blocks are slidably disposed on the forming base, the two sets of pusher blocks are distributed relative to each other, and each set of pusher blocks contains at least one pusher block; when the two sets of pusher blocks move in a mutually oriented direction, the two sets of pusher blocks respectively push the two sides of the zipper belt in a mutually approaching direction.

[0024] By adopting the above technical solution, the forked stop bar is driven to pass through the forming seat and extend into the two side fabric strips of the zipper belt. By driving the two sets of pusher sliders to move in opposite directions, the two side fabric strips of the zipper belt are pushed in a direction closer to each other. After being blocked by the forked stop bar, the two side fabric strips gradually tighten along the edge of the forked stop bar, which helps to pinch the zipper belt into a Y-shape, so as to meet the assembly requirements of the butterfly-shaped top stop.

[0025] Preferably, the pressing belt assembly further includes a hook body; the guide plate has a hook groove communicating with the chain groove, the hook body slides and engages with the hook groove, so that the hook body moves closer to or away from the fork stop; the hook body can extend into or out of the chain groove; the hook body is provided with a baffle to prevent the two fabric strips of the zipper belt from approaching each other; the baffle is provided with a beveled corner.

[0026] By adopting the above technical solution, the hook body is driven to extend out of the chain groove. With the help of the inclined guide structure of the front corner of the hook, the baffle is guided to smoothly and steadily pass between the two sides of the zipper tape, so that the two sides of the tape are naturally placed on the left and right sides of the baffle, separating the two sides of the tape. Then, the hook body is driven to approach the fork stop so that after the fork stop bar extends, it can be inserted more accurately between the two sides of the zipper tape.

[0027] Preferably, the pressing assembly further includes a fourth driving member, a slide rail fixing seat, and a fabric pressing plate. The fabric pressing plate includes a pressing part. The fourth driving member is used to drive the fabric pressing plate to move in a direction close to or away from the chain groove. The driving end of the fourth driving member is connected to the slide rail fixing seat. The slide rail fixing seat is provided with a fabric pressing slide rail, and the distribution direction of the fabric pressing slide rail is the same as the sliding direction of the hook body in the hook groove. The fabric pressing plate is connected with a fabric pressing slider, which slides and cooperates with the fabric pressing slide rail, and the fabric pressing slider and the fabric pressing slide rail are anti-detached. The hook body is provided with a pin that engages with the fabric pressing plate, and the fabric pressing plate has a slot that engages with the pin.

[0028] By adopting the above technical solution, the hook body extends out of the zipper groove, and with the help of the inclined guide structure of the beveled end of the hook, the baffle is guided smoothly and steadily into the space between the two sides of the zipper tape. This allows the two sides of the tape to be naturally positioned on the left and right sides of the baffle, separating the two sides of the tape. By driving the fabric pressure plate, the pin and the insertion port are interlocked, and at the same time, the pressing part of the fabric pressure plate and the hook clamp and fix the zipper tape. This prevents the two sides of the tape from lifting or flipping up, and provides a pre-tightening effect on the zipper tape, providing stable support for the subsequent installation process and ensuring the stability and reliable positioning of the zipper tape.

[0029] Preferably, the positioning slot is directly opposite the Y-shaped branch of the zipper tape; the assembly includes a sliding cover plate, a large slider slidably disposed on the sliding cover plate, and a punch slidably disposed on the positioning seat; the positioning seat is fixed to the sliding cover plate, and the large slider slides and engages with the sliding cover plate, so that the positioning seat is close to or away from the Y-shaped branch of the zipper tape; the punch slides and engages with the positioning slot, and the sliding direction of the punch is consistent with the sliding direction of the large slider; the punch is connected to a small slider.

[0030] By adopting the above technical solution, since the positioning slot is directly opposite the Y-shaped branch of the zipper belt, when the feeding mechanism engages the upper stop in the positioning slot, the large slider is driven to bring the positioning seat closer to the Y-shaped branch of the zipper belt, allowing the upper stop's buckle to pass through the zipper belt for installation. Simultaneously, the small slider is driven to slide the die, pushing the upper stop out of the positioning slot and releasing it from the engagement. This allows the upper stop to completely detach from the positioning slot and remain smoothly on the zipper belt.

[0031] Compared with the prior art, the present invention has the following beneficial effects: 1. By integrating clamping blocks and limiting strips through a single drive source, multiple positioning functions such as entry release, posture correction, and material handling are achieved. The correction unit matches the shape of the upper stop wing, forming a positioning trend that tightens towards the center, eliminating lateral movement, and ensuring that the upper stop maintains the preset benchmark within the discharge position. This significantly improves positioning consistency and repeatability, and solves the problems of easy deviation and interference of butterfly-shaped upper stops. The structure is compact and highly integrated. 2. The feeding mechanism solves the problems of material jamming, stacking, production interruption, and low assembly accuracy caused by the butterfly-shaped upper stop due to its light weight, easy swaying and deviation, and improper posture. It eliminates the accumulation of small deviations and material handling interference, requiring no manual assistance. It realizes the leap from semi-manual intervention to fully automatic, high-precision, and high-stability feeding, significantly improving assembly reliability and work efficiency; 3. Drive the hook to extend out of the chain groove, and guide the baffle at the front bevel to smoothly insert it between the fabric strips, so that the fabric strips on both sides naturally separate. The fabric pressure plate interlocks with the insertion port through the pin, and its pressing part and the hook together clamp the zipper strip to prevent the fabric strip from lifting or flipping, thus achieving pre-compression and providing a stable and reliable zipper strip posture for subsequent top stop installation; 4. Through a multi-layered structural design that integrates step-by-step guiding and separation of the zipper tape, pre-compression to prevent warping, Y-shaped precision forming, and top stop positioning and fastening, installation errors such as tape folding, misalignment, top stop deviation, and poor buckle bending are avoided from the source. While ensuring smooth process connections and accurate and reliable positioning, it can also effectively reduce tape jamming and machine downtime caused by unstable positioning, and reduce the frequency of equipment debugging and maintenance. It achieves fully automated continuous operation without manual intervention, and ensures a high degree of uniformity in top stop installation force and fastening shape, further improving the neatness of the finished product appearance and the strength of the connection, extending the overall service life of the zipper, and adapting to high-speed continuous production lines to achieve high-quality, high-stability, and high-economic large-scale production.

[0047] The following will refer to the appendices in the embodiments of the present invention. Figures 1 to 13The technical solutions in the embodiments of the present invention are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1:

[0048] A butterfly-shaped top-stop feeding mechanism, as shown in the reference. Figure 1 It includes material handling component 1, transport track 2, material control component 3, material conveying component 4, and positioning seat 5.

[0049] It should be noted that, referring to Figure 2 In this embodiment, the upper stop 17 is a copper butterfly bracket, comprising a butterfly-shaped body 171 and buckles 172. The body 171 has an axially symmetrical structure, including two forewings and two hindwings, with the forewings slightly longer than the hindwings, causing a portion of the forewings to protrude beyond the hindwings. The buckles 172 are long rods, and the buckles 172 slope outwards from the body 171 towards the body 171, with a total of four buckles 172. The four buckles 172 are divided into two groups, with one group consisting of two buckles 172, for a total of two groups. The two buckles 172 in one group are symmetrically located at the ends of the two forewings of the body 171, and the two buckles 172 in the other group are symmetrically located at the ends of the two hindwings of the body 171. During installation, the upper stop 17 is transported to the area above the Y-shaped branch of the zipper tape, and the buckles 172 are driven through the tape and bent to complete the installation.

[0050] Reference Figure 1 The material handling component 1 is used to handle materials, arranging the upper stops 17 in a desired order and outputting them to the transport track 2. In this embodiment, the material handling component 1 is a vibratory feeder. The upper stops 17 are positioned with their bodies 171 facing down and their feet 172 facing up, arranged sequentially in a manner where "the front wing of the preceding upper stop 17 abuts against the front wing of the following upper stop 17," forming a continuous and orderly feeding sequence. The material handling component 1 is existing technology and will not be described in detail here. During material handling, the scattered upper stops 17 are placed into the material handling component 1. The vibration force of the material handling component 1 causes the bodies 171 of the upper stops 17 to face down and their feet 172 to face up, arranged sequentially in a manner where "the front wing of the preceding upper stop 17 abuts against the front wing of the following upper stop 17," and then output to the transport track 2. The downward orientation of the bodies 171 of the upper stops 17 has the advantage of a more stable center of gravity and is less prone to tipping over.

[0051] Reference Figure 3 and Figure 4The transport track 2 is elongated, with one end serving as the feed end. The discharge end of the material handling component 1 connects to the feed end of the transport track 2. The transport track 2 forms a conveying channel 6 for the passage of the upper stop 17. The conveying channel 6 extends through the feed end and the upper surface of the transport track 2, connecting the conveying channel 6 to the discharge end of the material handling component 1. The arrangement of the upper stop 17 in the conveying channel 6 is consistent with that of the discharge end of the material handling component 1. Thus, the upper stop 17 output from the material handling component 1 can be continuously fed into the conveying channel 6. A guide block 7 is provided on the transport track 2. The guide block 7 is used to restrict the posture of the upper stop 17 in the conveying channel 6. The guide block 7 is an inverted U-shaped block and is connected to the transport track 2 by bolts. One side of the guide block 7 extends into the conveying channel 6 from above the transport track 2. When the drive stop 17 enters the conveying channel 6, the two sets of latches 172 of the stop 17 are located on both sides of the guide block 7, and the body 171 of the stop 17 is located below the guide block 7. This allows the conveying channel 6 to allow the stop 17 to pass through in the required posture, thereby eliminating the stop 17 with abnormal posture and ensuring that the stop 17 entering the next process maintains the correct posture. The guide block 7 further optimizes the posture consistency and conveying stability of the conveying, effectively avoiding material jamming, stacking, or workstation docking deviation caused by the incorrect posture of the stop 17, improving the reliability and efficiency of feeding and subsequent assembly processes. At the same time, the guide block 7 can prevent the stop 17 from leaving the track above the conveying channel 6.

[0052] Reference Figure 3 and Figure 4 The end of the conveying channel 6 is formed with a discharge position 61, which is just enough for a single top stop 17 to be taken out from above the conveying channel 6. The material control component 3 is used to control the top stop 17 of the conveying channel 6 to enter the discharge position 61 and to correct the posture of the top stop 17 at the discharge position 61.

[0053] In use, the scattered upper stop 17s are placed into the material handling component 1. The vibration of the material handling component 1 causes the upper stop 17s to face downwards with their bodies 171 and their buckles 172 upwards, arranged sequentially in a manner where the front wing of the previous upper stop 17 abuts against the front wing of the next upper stop 17. They are then output into the conveying channel 6 of the transport track 2. Guide blocks 7 ensure that the conveying channel 6 only allows the upper stop 17s to pass through in the required posture, thereby eliminating upper stop 17s with abnormal postures. This effectively avoids material jamming, stacking, or workstation misalignment caused by disordered posture of the upper stop 17s. The upper stop 17 of the conveying channel 6 is controlled by the material control component 3 to enter the discharge position 61, and the posture of the upper stop 17 is further corrected to ensure that the upper stop 17 is in a precise position. Finally, the material conveying component 4 removes the upper stop 17 from above the conveying channel 6. The setting of the material control component 3 can keep the upper stop 17 in accurate positioning and uniform posture at the discharge position 61, which significantly improves the orderliness and positioning accuracy of the upper stop 17 removal position, provides a reliable foundation for subsequent gripping, assembly and other processes, and helps to improve the overall equipment operation stability and work efficiency.

[0054] Specifically, refer to Figure 3 and Figure 4 The material control assembly 3 includes a material control chute 31 connected to the discharge position 61, a clamping block 32 slidably disposed in the material control chute 31, and a first driving member 34 for driving the clamping block 32 to slide. The material control chute 31 is formed on the side wall of the transport track 2, and the material control chute 31 is distributed along the width direction of the transport track 2 and extends through the transport track 2. The top end of the material control chute 31 is connected to the discharge position 61, and the clamping block 32 slides and engages along the length direction of the material control chute 31.

[0055] Reference Figure 3 and Figure 4 The clamping block 32 is elongated and distributed along the width of the transport track 2. The clamping block 32 includes an integrally formed support portion 321 and a connecting portion 322. The support portion 321 supports the upper stop 17 of the discharge position 61. Within the sliding stroke of the clamping block 32, the support portion 321 consistently supports the upper stop 17 of the discharge position 61, ensuring that the upper stop 17 of the discharge position 61 is at the same height as the upper stop 17 of the conveying channel 6. The sidewall shape of the discharge position 61 is adapted to the upper stop 17, effectively preventing the upper stop 17 from shifting its posture or sliding with the clamping block 32 within the sliding stroke range of the clamping block 32.

[0056] Continue to refer to Figure 3 and Figure 4 A limiting strip 33 is provided on the support part 321. The limiting strip 33 is used to restrict the upper stop 17 from entering the discharge position 61. The limiting strip 33 is strip-shaped and distributed along the length direction of the clamping block 32. The limiting strip 33 is integrally formed on the top side of the support part 321. The limiting strip 33 is close to one end of the support part 321 and far away from the connecting part 322. Two limiting strips 33 are provided, and the two limiting strips 33 are distributed opposite to each other along the width direction of the clamping block 32. Each limiting strip 33 has an inclined correction part 331. The correction part 331 is used to correct the posture of the upper stop 17 of the discharge position 61. The correction part 331 is located at one end of the limiting strip 33 and is inclined from the direction close to the connecting part 322 to the direction away from the connecting part 322.

[0057] Reference Figure 3 and Figure 4 The first driving component 34 is a cylinder in the prior art. The driving end of the first driving component 34 is fixedly connected to the connecting part 322 of the clamping block 32. The clamping block 32 can be driven to slide in the material control groove 31 by the first driving component 34, so that the limiting strip 33 extends into or out of the discharge position 61.

[0058] In use, the clamping block 32 is driven by the first driving member 34 to slide along the material control groove 31, so that the limiting strip 33 extends out of the discharge position 61, and the upper stop 17 closest to the discharge position 61 in the conveying channel 6 can enter the discharge position 61; then the first driving member 34 drives the clamping block 32 again, so that the limiting strip 33 partially extends into the discharge position 61, the correction part 331 abuts against and drives the front wing of the body 171, and the correction part 331 is located at the part of the front wing that protrudes from the rear wing. The shape of the correction part 331 matches the position where the front wing is abutted, thereby pushing the upper stop 17 of the discharge position 61 to press against the wall of the conveying channel 6, so as to achieve position correction. Since the upper stop 17 itself is a miniature component, the straightening unit 331 can effectively solve the problems of the upper stop 17 being lightweight, easy to shake, easy to deviate, and difficult to accurately control its posture. Through precise pressing and fitting abutment correction, the small gap error between the upper stop 17 and the channel is reduced, ensuring that the posture and position are consistent when multiple upper stops 17 are continuously fed, and greatly reducing the impact of the accumulation of small deviations on the subsequent installation accuracy.

[0059] The material conveying component 4 is used to transfer the upper stop 17 of the discharge position 61 to the positioning seat 5. According to the control system settings, when the material conveying component 4 removes the upper stop 17 of the discharge position 61, the first driving component 34 synchronously drives the clamping block 32 to slide along the material control slide 31, so that the limiting strip 33 fully extends into the discharge position 61, blocking and isolating the subsequent upper stop 17 waiting to be discharged in the conveying channel 6, avoiding the subsequent upper stop 17 rushing into the discharge position 61 at the moment of material picking, and interfering with or colliding with the material picking action, thus ensuring that the material picking process is smooth and uninterrupted.

[0060] Through the structural design of the clamping block 32 and the limiting strip 33, multiple positioning functions such as entry release, posture correction, and material picking and blocking can be achieved through a single drive source. While simplifying the overall structure, it makes the connection between each process more compact and reliable. Moreover, the action switching is fast and there are no unnecessary pauses. With the continuous feeding of the vibratory feeder, it can meet the cycle time requirements of high-speed automated production lines. In addition, the correction part 331 matches the shape of the front wing part of the upper stop 17, and the two correction parts 331 form a positioning trend that drives the upper stop 17 to tighten towards the center, further ensuring that the upper stop 17 is centered and corrected, eliminating lateral movement margin, and keeping the upper stop 17 always in the preset reference position within the discharge position 61. This effectively improves the positioning consistency and repeatability accuracy, and provides a more stable and reliable upper stop 17 state for subsequent gripping and assembly processes. It effectively solves the problems of positioning deviation and action interference that are prone to occur during the feeding process of the butterfly-shaped upper stop 17. The overall technical solution is ingeniously conceived and highly integrated.

[0061] Furthermore, to prevent the material conveying component 4 from empty picking or grabbing due to the absence of an upper stop 17 at the discharge position 61, the transport track 2 is also equipped with a detection element for detecting whether the discharge position 61 has an upper stop 17 and an indicator element for indicating whether an upper stop 17 is present. The detection element is an infrared sensor, with its probe facing the discharge position 61. It senses the presence of an upper stop 17 within the discharge position 61 through infrared light reflection and distance changes. In this embodiment, the indicator element is an indicator light, specifically a red light, and is electrically connected to the detection element. The infrared sensor, indicator element, and related control logic are all existing technologies and will not be described in detail. During the detection process, if the discharge position 61 lacks an upper stop 17, the indicator light illuminates, and the material conveying component 4 is prohibited from operating; if the discharge position 61 has an upper stop 17, the indicator light goes out, and the material conveying component 4 proceeds to the next step. This effectively avoids malfunctions such as empty picking or empty feeding, prevents equipment from running idle or interfering, ensures stable and reliable connection between the upper stop 17 feeding and subsequent processes, and improves the continuity and safety of the entire machine operation.

[0062] Specifically, refer to Figure 5 The material handling assembly 4 includes a Z-axis sliding part, an X-axis sliding part, a Y-axis sliding part, and a gripper 41.

[0063] Reference Figure 5 The Z-axis sliding part includes a Z-axis slider 42 and a Z-axis drive 43 for driving the Z-axis slider 42 to slide. The Z-axis slider 42 is a rectangular block and horizontally distributed, and the X-axis sliding part is disposed on the Z-axis slider 42. The Z-axis drive 43 is a cylinder, and the driving end of the Z-axis drive 43 is connected to the Z-axis slider 42, and the Z-axis drive 43 can drive the Z-axis slider 42 to move in the vertical direction.

[0064] Reference Figure 5 The X-axis sliding part includes an X-axis slider 44 and an X-axis drive 45 for driving the X-axis slider 44 to slide. The X-axis slider 44 is also rectangular in shape, and the Y-axis sliding part is disposed on the X-axis slider 44. The X-axis drive 45 is a cylinder, and the X-axis drive 45 is disposed on the Z-axis slider 42. The driving end of the X-axis drive 45 is connected to the X-axis slider 44, and the X-axis drive 45 can drive the X-axis slider 44 to move along the length direction of the Z-axis slider 42.

[0065] Reference Figure 5 The Y-axis sliding part includes a Y-axis slider 46 and a Y-axis drive member 47 for driving the Y-axis slider 46 to slide. A gripper 41 is disposed on the Y-axis slider 46. The Y-axis drive member 47 is a cylinder and is disposed on the X-axis slider 44. The drive end of the Y-axis drive member 47 is connected to the Y-axis slider 46, and the Y-axis drive member 47 can drive the Y-axis slider 46 to move along the length direction of the X-axis slider 44.

[0066] Continue to refer to Figure 5In this embodiment, the gripper 41 is a conventional rotary pneumatic gripper. The gripper 41 includes two gripper arms, meaning it has a rotational function. In this embodiment, the rotation angle of the gripper 41 is limited to a 180° reciprocating swing. Thus, through the cooperation of the X-axis sliding part, the Y-axis sliding part, and the Z-axis sliding part, the position of the gripper 41 can be adjusted, and the upper stop 17 can be clamped and removed to the discharge position 61 by the gripper 41. In other embodiments, the gripper 41 can also be a vacuum suction cup, a vacuum nozzle, or other types of pneumatic grippers.

[0067] In addition, refer to Figure 3 and Figure 5 To facilitate the insertion of the gripper 41 into the discharge position 61 to clamp the upper stop 17, a clearance groove 9 is also provided on the transport track 2. The clearance groove 9 allows the gripper 41 to be clamped inside, extends to the top of the transport track 2, and is connected to the discharge position 61. Correspondingly, the support part 321 of the clamping block 32 forms a clearance area 10, which is connected to the clearance groove 9. The clearance groove 9 and the clearance area 10 on the clamping block 32 are designed to correspond, allowing the gripper 41 claw arm to extend into the upper and lower sides of the body 171 without obstruction. With the precise positioning after correction, it avoids clamping the upper stop 17 due to positional deviation.

[0068] When the upper stop 17 is removed from the discharge position 61, the gripper 41 passes through the clearance groove 9 and extends into the discharge position 61 through the cooperation of the X-axis sliding part, Y-axis sliding part and Z-axis sliding part. The two claw arms are located on the upper and lower sides of the body 171 respectively. The gripper 41 is driven to clamp the upper stop 17. The Z-axis drive 43 drives the Z-axis slider 42 to move upward, which drives the gripper 41 upward to remove the upper stop 17. At this time, the upper stop 17 on the gripper 41 has its latch 172 facing upward and its body 171 facing downward. The first drive 34 will synchronously drive the clamping block 32 to slide along the material control groove 31, so that the limiting strip 33 fully extends into the discharge position 61, blocking and isolating the upper stops 17 waiting to be discharged in the conveying channel 6, ensuring that the material picking process is smooth and uninterrupted.

[0069] Reference Figure 1 and Figure 6The positioning seat 5 is located above the zipper tape. A positioning groove 8 is formed at the bottom of the positioning seat 5, and the positioning groove 8 is directly opposite the Y-shaped branch of the zipper tape. The positioning groove 8 engages with the upper stop 17. Because the buckles 172 of the upper stop 17 are all inclined outwards, during the process of inserting the upper stop 17 into the positioning groove 8, the groove wall of the positioning groove 8 compresses the buckles 172, causing the buckles 172 to undergo elastic deformation. The restoring elastic force of the buckles 172 acts in the opposite direction on the groove wall of the positioning groove 8, thereby achieving reliable locking and positioning between the upper stop 17 and the positioning groove 8. When the upper stop 17 engages with the positioning groove 8, the body 171 of the upper stop 17 faces upwards and the buckles 172 face downwards (towards the lower zipper tape). Therefore, by driving the upper stop 17 within the positioning groove 8, the buckles 172 can be driven through the fabric tape, facilitating the installation of the upper stop 17. The bottom of the positioning slot 8 is also provided with a clearance slot 11, which is used to provide clearance space for the opening action of the gripper 41.

[0070] Reference Figure 1 and Figure 6 Since the upper stop 17 is removed from the discharge position 61 with the buckle 172 facing upward and the body 171 facing downward, the upper stop 17 is rotated by rotating the gripper 41 by 180°. The position of the gripper 41 is adjusted by the cooperation of the X-axis sliding part, the Y-axis sliding part and the Z-axis sliding part, so that the gripper 41 drives the upper stop 17 to extend into the positioning slot 8. The upper stop 17 is engaged with the positioning slot 8, the gripper 41 is opened, and the claw arm located above returns to the initial position from the relief slot 11 by the X-axis sliding part, the Y-axis sliding part and the Z-axis sliding part, thus completing the feeding of the upper stop 17.

[0071] The implementation principle of this embodiment is as follows: During loading, the scattered top stops 17 are placed into the material handling component 1. The vibration force of the material handling component 1 is used to make the body 171 of the top stops 17 face down and the buckle 172 face up. They are arranged in sequence in the manner of "the front wing of the previous top stop 17 abutting the front wing of the next top stop 17". Then they are output to the conveying channel 6 of the transport track 2. The guide block 7 makes the conveying channel 6 only allow the top stops 17 to pass through in the required posture, thereby removing the top stops 17 with abnormal posture and effectively avoiding material jamming, stacking or workstation docking deviation caused by the disordered posture of the top stops 17.

[0072] Next, the clamping block 32 is driven by the first driving member 34 to slide along the material control groove 31, so that the limiting strip 33 extends out of the discharge position 61, and the upper stop 17 closest to the discharge position 61 in the conveying channel 6 can enter the discharge position 61; then the first driving member 34 drives the clamping block 32 again, so that the limiting strip 33 partially extends into the discharge position 61, the correction part 331 abuts against and drives the front wing of the body 171, and the correction part 331 is located in the part of the front wing that protrudes from the rear wing. The shape of the correction part 331 matches the position where the front wing is abutted, thereby pushing the upper stop 17 of the discharge position 61 to press against the wall of the conveying channel 6, and realizing position correction. The correction unit 331 effectively solves the problems of the upper stop 17 being lightweight, easy to shake, easy to deviate, and difficult to control its posture precisely. Through precise fitting and abutment correction, it avoids positioning failure due to its small size. At the same time, it can reduce the gap error between the upper stop 17 and the channel, ensuring that the posture and position are consistent when multiple upper stops 17 are continuously fed, and greatly reducing the impact of the accumulation of small deviations on the subsequent installation accuracy.

[0073] The X-axis sliding part, Y-axis sliding part, and Z-axis sliding part work together to allow the gripper 41 to pass through the clearance groove 9 and extend into the discharge position 61. The two claw arms are located on the upper and lower sides of the body 171, respectively. The gripper 41 is driven to clamp the upper stop 17. The Z-axis drive 43 drives the Z-axis slider 42 to move upward, which in turn drives the gripper 41 to lift the upper stop 17 out. The first drive 34 synchronously drives the clamping block 32 to slide along the material control groove 31, so that the limit bar 33 fully extends into the discharge position 61, blocking and isolating the subsequent upper stop 17 waiting to be discharged in the conveying channel 6. This prevents the subsequent upper stop 17 from rushing into the discharge position 61 at the moment of material picking, thus avoiding interference or collision with the material picking action and ensuring a smooth and uninterrupted material picking process.

[0074] Next, by rotating the gripper 41 180°, the upper stop 17 is rotated. Then, through the cooperation of the X-axis sliding part, Y-axis sliding part and Z-axis sliding part, the position of the gripper 41 is adjusted so that the gripper 41 drives the upper stop 17 to extend into the positioning slot 8. The upper stop 17 engages with the positioning slot 8, the gripper 41 is opened, and then the X-axis sliding part, Y-axis sliding part and Z-axis sliding part are used to restore it to the initial position, thus completing the loading of the upper stop 17.

[0075] This solves the problems of material jamming, stacking, production interruption, and low assembly accuracy caused by the butterfly-shaped top stop 17 due to its light weight, easy shaking, easy deviation, and improper posture arrangement. It effectively eliminates the accumulation of small deviations and material picking interference, eliminates the need for manual assistance and supervision, and greatly improves the material feeding and positioning accuracy and assembly reliability of the top stop 17. It realizes the leap from semi-manual intervention to fully automatic, high-precision, and high-stability material feeding, and significantly improves assembly reliability and operation efficiency. Example 2:

[0076] One type of upper stop 17 machine, refer to Figure 7The system includes a chassis 18 and a feeding mechanism as described in Embodiment 1. The chassis 18 is rectangular and is distributed vertically. Four casters 19 are provided at the bottom of the chassis 18, and the four casters 19 are located near the four corners of the bottom of the chassis 18 to facilitate moving and transporting the chassis 18.

[0077] Reference Figure 7 The machine also includes a guide frame 40, a mounting mechanism 12, and a belt pulling mechanism 13. The guide frame 40, mounting mechanism 12, feeding mechanism, and belt pulling mechanism 13 are all mounted on the machine housing 18. The guide frame 40, mounting mechanism 12, feeding mechanism, and belt pulling mechanism 13 are distributed sequentially along the conveying direction of the zipper belt.

[0078] The guide frame 40 guides the zipper tape into the mounting mechanism 12. The guide frame 40 is existing technology and commonly used in zipper production equipment, so it will not be described in detail. The mounting mechanism 12 installs the top stop 17 in the positioning slot 8 onto the zipper tape. The pull mechanism 13 drives the zipper tape forward, advancing one zipper segment at a time. In use, a continuous, uncut zipper tape (connecting multiple independent zipper segments) is passed sequentially through the guide frame 40, the mounting mechanism 12, the feeding mechanism, and the pull mechanism 13. The pull mechanism 13 intermittently drives the zipper tape, advancing one zipper segment at a time. Simultaneously, the feeding mechanism feeds the top stops 17 one by one to the mounting mechanism 12, and the mounting mechanism 12 installs the zipper segments one by one, achieving continuous installation of the top stops 17.

[0079] Specifically, refer to Figure 8 The mounting mechanism 12 includes a mounting bracket 20 mounted on the chassis 18, a pressure belt assembly mounted on the mounting bracket 20, and an assembly assembly. The pressure belt assembly drives the zipper belt to form a Y shape, and the assembly assembly drives the upper stop 17 in the positioning seat 5 to be mounted at the branch of the Y shape of the zipper belt.

[0080] Reference Figure 7 and Figure 8 The mounting frame 20 is an inverted L-shaped block, with one end fixedly connected to the machine frame. A fixing plate is provided on the transport track 2, and the fixing plate is connected to both the transport track 2 and the mounting frame 20 by bolts, thereby connecting the transport track 2 to the mounting frame 20 via the fixing plate. A base 21 is also provided on the mounting frame 20.

[0081] Furthermore, refer to Figure 9 and Figure 10The pressing assembly includes a lower die base 121, a guide plate 122, a forming seat 123, and a forked stop bar 124 slidably disposed on the forming seat 123. The lower die base 121 is a rectangular block, distributed vertically, and mounted on a mounting frame 20. The lower die base 121 is connected to the mounting frame 20 via connecting blocks. The guide plate 122 is disposed on the lower die base 121 and connected to the lower die base 121 by bolts. The guide plate 122 is a long plate. The guide plate 122 has chain grooves 14 for sliding of the zipper belt, distributed along the length of the guide plate 122 and extending through both ends of the guide plate 122.

[0082] Reference Figure 9 and Figure 10 The forming seat 123 is disposed on the lower mold base 121. The forming seat 123 is a long strip-shaped block and is located at one end of the guide plate 122. The guide plate 122 and the forming seat 123 are distributed sequentially along the forward direction of the zipper belt. The forked stop bar 124 is a long bar and is distributed along the length direction of the lower mold base 121. The forked stop bar 124 is located inside the lower mold base 121, and its top end protrudes from the forming seat 123. The forked stop bar 124 slides and engages with the forming seat 123 along its axial direction, so that the forked stop bar 124 can slide into or out of the forming seat 123 relative to it. That is, the forked stop bar 124 can extend and retract on the forming seat 123. A second driving member 138 is provided at the end of the lower mold base 121 opposite to the forming base 123. The second driving member 138 is a cylinder and is used to drive the forked stop bar 124 to slide along its axial direction. The driving end of the second driving member 138 is connected to the forked stop bar 124. Thus, the forked stop bar 124 is driven to slide along its axial direction by the second driving member 138, causing the forked stop bar 124 to slide into or out of the forming base 123.

[0083] Reference Figure 10 and Figure 11 A fabric pusher slider 125 is slidably disposed on the forming base 123. There are two sets of fabric pusher sliders 125, which are distributed opposite to each other along the length of the forming base 123. Each set of fabric pusher sliders 125 contains at least one fabric pusher slider 125. When the two sets of fabric pusher sliders 125 move in a direction facing each other, the two sets of fabric pusher sliders 125 respectively push the two sides of the zipper tape in a direction that brings them closer to each other.

[0084] Reference Figure 9 and Figure 11 In this embodiment, there is only one pusher slider 125 in each set of pusher sliders 125, meaning there are a total of two pusher sliders 125. A first groove is provided on the molding base 123. 22 and second chute 23, first chute 22 and the second groove 23 respectively extend through the first and second ends of the forming base 123 along its length direction, the first groove 22 and the second groove 23 are spaced apart along the width direction of the molding seat 123, and the first groove 22 is close to the guide plate 122. The pusher block 125 includes a drive block 1251, a first limiting block 1252 and a second limiting block 1253 disposed on the drive block 1251. The first limiting block 1252 and the second limiting block 1253 are both located on the side of the drive block 1251 facing the forming seat 123. The first limiting block 1252 forms a first fabric belt gap 24 for the fabric belt to pass through, and the first limiting block 1252 and the first sliding groove are... 22. Sliding engagement: The second limiting block 1253 forms a second fabric belt gap 25 for the fabric belt to pass through, and the second limiting block 1253 slides into the second sliding groove 23. By driving the driving block 1251 to slide along the length direction of the forming seat 123, the first limiting block 1252 can be simultaneously moved along the first sliding groove. 22 slides, and the second limiting block 1253 slides along the second slide groove 23.

[0085] When installing the zipper tape, pass the zipper tape through the zipper groove 14 and place the end of one zipper segment on the forming seat 123. Then, place the two sides of the tape at the end into the first tape gap 24 and the second tape gap 25 respectively, so that the two tapes fall into the two pusher sliders 125. At this time, the fork stop bar 124 faces the gap between the two tapes.

[0086] Reference Figure 10 and Figure 11 A third driving component 139 is provided on the lower mold base 121. The third driving component 139 is a cylinder. The driving end of the third driving component 139 is connected to the driving block 1251. The third driving component 139 can drive the pusher slider 125 to slide as a whole, and simultaneously cause the first limiting block 1252 to slide along the first groove. 22 Slide, the second limiting block 1253 slides along the second slide groove 23. The number of third driving members 139 corresponding to the push cloth slider 125 is set to two, and the two third driving members 139 are connected one-to-one to the driving blocks 1251 of the two push cloth sliders 125.

[0087] Furthermore, since the two push-cloth sliders 125 are distributed relative to each other, the two third drive members 139 can drive the two push-cloth sliders 125 to slide in directions facing each other or away from each other. When the two third drive members 139 drive the two push-cloth sliders 125 to move in directions facing each other, the two push-cloth sliders 125 push the two sides of the zipper tape towards each other.

[0088] Reference Figure 10 and Figure 12The pressing assembly also includes a fourth drive member 128, a slide rail fixing seat 129, and a cloth pressing plate 130. The cloth pressing plate 130 includes a pressing part 1301. The fourth drive member 128 is mounted on the machine base 21 and is a cylinder. The fourth drive member 128 is used to drive the cloth pressing plate 130 to move in a direction close to or away from the chain groove 14. The driving end of the fourth drive member 128 is connected to the slide rail fixing seat 129.

[0089] Additionally, refer to Figure 9 and Figure 11 To ensure that the fork stop bar 124 can accurately extend into both sides of the zipper tape, the tape pressing assembly also includes a hook body 126, a baffle bar 140, and a limit bar 141.

[0090] Reference Figure 10 and Figure 11 A hook groove 15 is provided at one end of the guide plate 122 near the forming base 123. The hook groove 15 extends along the length of the guide plate 122 and connects to the chain groove 14, extending to the bottom wall of the guide plate 122. The hook body 126 is elongated, with one end located inside the lower mold base 121 and the other end passing through the hook groove 15 and located in the chain groove 14. By driving the hook body 126 to move vertically, the hook body 126 can extend or retract relative to the chain groove 14, that is, the hook body 126 extends into or out of the chain groove 14.

[0091] Reference Figure 11 and Figure 12 The baffle rod 140 is a rectangular long rod, distributed in the same direction as the guide plate 122. The baffle rod 140 is connected to one end of the hook body 126 located inside the lower mold base 121. The lower mold base 121 also has an inner sliding groove 26, which is slidably fitted with an inner slide seat 142, through which the baffle rod 140 passes. The inner slide seat 142 and the inner sliding groove 26 slide and engage along the extension and retraction direction of the hook body 126 relative to the chain groove 14. The lower mold base 121 is also provided with a fifth driving member 143, which is a cylinder. The driving end of the fifth driving member 143 extends into the inner sliding groove 26 and is connected to the inner slide seat 142. Thus, the fifth driving member 143 drives the hook body 126 to extend into or out of the chain groove 14.

[0092] Reference Figure 11 and Figure 12The hook body 126 slides along the length of the guide plate 122 and engages with the hook groove 15, allowing the hook body 126 to move closer to or further away from the forked stop bar 124. The stop bar 140 slides along its length and engages with the inner slide block 142. The limiting bar 141 is also a rectangular long bar, and the end of the stop bar 140 away from the hook body 126 is connected to the limiting bar 141. The limiting bar 141 and the distribution direction of the stop bar 140 are perpendicular, thereby limiting the stop bar 140. A sixth driving component, which is a cylinder, is provided on the inner slide 142. The sixth driving component is used to drive the hook body 126 to move along the length direction of the guide chain plate 122. The driving end of the sixth driving component is connected to the limiting rod 141, so that the limiting rod 141 is driven by the sixth driving component, which drives the baffle rod 140 to slide along its length direction in the inner slide 142, thereby driving the hook body 126 to move along the length direction of the guide chain plate 122, so that the hook body 126 moves closer to or away from the forked baffle rod 124.

[0093] Reference Figure 10 and Figure 12 A fabric-pressing slide rail 131 is provided on the slide rail fixing base 129. The distribution direction of the fabric-pressing slide rail 131 is the same as the sliding direction of the hook body 126 in the hook groove 15. A fabric-pressing plate 130 is connected to a fabric-pressing slider 132, which slides and engages with the fabric-pressing slide rail 131, and the fabric-pressing slider 132 and the fabric-pressing slide rail 131 are anti-detached. In this embodiment, the fabric-pressing plate 130 is located above the chain groove 14, and the pressing part 1301 of the fabric-pressing plate 130 faces the chain groove 14, so that the fabric-pressing plate 130 can slide back and forth along the zipper belt.

[0094] Reference Figure 9 and Figure 11 The hook body 126 is provided with a baffle 127 for preventing the two fabric strips of the zipper tape from approaching each other, and a pin 133 for interlocking with the fabric pressure plate 130. The baffle 127 is a rectangular plate and is distributed along the length of the hook body 126. The baffle 127 has a chamfered portion 1271, which has an inclined guiding structure. This reduces the lateral dimension of the end of the baffle 127 and forms a guide slope, making it easier for the baffle 127 to enter the gap between the two fabric strips of the zipper tape. This effectively avoids interference, scratching, or jamming between the baffle 127 and the edge of the fabric strip, thus enabling the baffle 127 to be smoothly inserted and positioned in the working position. The fabric pressure plate 130 has an insertion port 16, which is square and extends through the pressing part 1301. The pin 133 is a square long rod. The pin 133 is distributed along the length of the hook body 126, and the length of the baffle 127 is greater than the length of the pin 133. The pin 133 and the socket 16 are directly opposite each other in the vertical direction, and the pin 133 and the socket 16 are inserted into each other.

[0095] When the zipper tape is installed, the fifth driving component 143 drives the hook body 126 to extend out of the zipper tape groove 14. With the help of the inclined guide structure of the guide angle part 1271 at the front end of the hook, the baffle 127 is guided to smoothly and steadily pass between the two sides of the zipper tape, so that the two sides of the tape are naturally placed on the left and right sides of the baffle 127, separating the two sides of the tape. The fourth driving component 128 drives the fabric pressure plate 130 to move in the vertical direction, and the pin 133 and the insertion port 16 are inserted into each other. At the same time, the pressing part 1301 of the fabric pressure plate 130 and the hook clamp and fix the zipper tape, which can prevent the two sides of the tape from lifting or flipping, and pre-tighten the zipper tape, providing stable support for the subsequent installation process of the upper stop 17, ensuring the stability of the zipper tape posture and reliable positioning.

[0096] Subsequently, the sixth driving component drives the hook body 126 to approach the fork stop bar 124. Since the pin 133 is inserted into the insertion port 16, it drives the fabric pressure plate 130 and the fabric pressure slider 132 to slide, simultaneously driving the zipper tape of the separated parts of the two fabric tapes to approach the fork stop bar 124. Then, the second driving component 138 drives the fork stop bar 124 to pass through the forming seat 123, so that the fork stop bar 124 can accurately extend into the two fabric tapes of the zipper tape. Two third drive components 139 drive two pusher sliders 125 to move in opposite directions, pushing the two sides of the zipper tape towards each other. After being blocked by the fork stop bar 124, the two sides of the tape gradually tighten along the edge of the fork stop bar 124, making the zipper tape Y-shaped. Then, the upper stop 17 on the positioning seat 5 is installed at the branch of the Y-shape of the zipper tape by the assembly component. Finally, all components are driven to reset, and the zipper tape mechanism 13 drives the zipper tape forward by one zipper segment length, so that the next round of installation work can be carried out.

[0097] Additionally, refer to Figure 9 A guide groove 27 is provided at the forming seat 123 corresponding to the upper stop 17 buckle 172. The guide groove 27 is used to guide the buckle 172 of the upper stop 17 to bend correctly. There are four guide grooves 27, each corresponding to one of the four buckles 172, and all four guide grooves 27 are close to the fork stop bar 124.

[0098] Specifically, refer to Figure 7 and Figure 13The assembly includes a sliding cover plate 134, a large slider 135 slidably disposed on the sliding cover plate 134, and a punch 136 slidably disposed on the positioning seat 5. The sliding cover plate 134 is connected to the machine base 21, and is elongated in shape, with the sliding cover plate 134 distributed vertically. The large slider 135 slides vertically and engages with the sliding cover plate 134. The positioning seat 5 is fixed on the sliding cover plate 134 and is located near the bottom of the large slider 135. The punch 136 slides into the positioning slot 8, and the sliding direction of the punch 136 is consistent with the sliding direction of the large slider 135. A small slider 137 is connected to the punch 136 and slides within the sliding cover plate 134.

[0099] Since the positioning slot 8 is directly opposite the Y-shaped branch of the zipper tape, when the feeding mechanism engages the upper stop 17 in the positioning slot 8, the large slider 135 is driven to bring the positioning seat 5 closer to the Y-shaped branch of the zipper tape, allowing the buckle 172 of the upper stop 17 to pass through the zipper tape for installation. Simultaneously, the small slider 137 is driven to slide the die 136 vertically, pushing the upper stop 17 out of the positioning slot 8, releasing the engagement between the upper stop 17 and the positioning slot 8, thus completely detaching the upper stop 17 from the positioning slot 8 and allowing it to remain smoothly on the zipper tape. After completion, the mechanism resets, and the feeding mechanism reloads for the next installation operation.

[0100] Reference Figure 13 The base 21 is equipped with a drive assembly for driving the large slider 135 and the small slider 137 to slide vertically. The drive assembly includes a drive motor 28, a first helical gear 29, a second helical gear 30, and a main shaft 35.

[0101] Reference Figure 13 A drive motor 28 is mounted on a base. The axle of the first helical gear 29 is vertically oriented, and the output shaft of the drive motor 28 is connected to the axle of the first helical gear 29. Both the first helical gear 29 and the second helical gear 30 are 45-degree helical gears. The second helical gear 30 meshes with the first helical gear 29, and the axle of the second helical gear 30 is perpendicular to the axle of the first helical gear 29, thereby achieving power reversal. The axle of the second helical gear 30 is connected to a main shaft 35, and the main shaft 35 is oriented in the same direction as the axle of the second helical gear 30. A turntable 36 is mounted on the main shaft 35. The turntable 36 is circular, and a connecting shaft 37 is mounted on the turntable 36. The connecting shaft 37 is distributed along the length of the main shaft 35 and is located near the edge of the turntable 36. A first link 38 and a second link 39 are rotatably connected on the connecting shaft 37. The first link 38 and the second link 39 are closely arranged along the length of the connecting shaft 37, and the first link 38 is close to the turntable 36.

[0102] During operation, the drive motor 28 drives the first helical gear 29 to rotate, which in turn drives the second helical gear 30, the main shaft 35, and the turntable 36 to rotate. Since the connecting shaft 37 is eccentrically positioned at the edge of the turntable 36, it rotates in a circular motion with each revolution of the turntable 36. Driven by the connecting shaft 37, the first and second linked rings 38 and 39 rotate eccentrically, thereby pushing the large slider 135 and the small slider 137 to reciprocate vertically, achieving linear driving action in the vertical direction.

[0103] The drive motor 28 reverses its direction through a pair of 45° helical gears, driving the horizontal main shaft 35 to rotate and achieve power reversal. One rotation of the eccentric turntable 36 on the main shaft 35 causes the small slider 137 and the large slider 135 to move vertically once and then reset via two connecting rings. After being limited by the sliding cover plate 134, both the small slider 137 and the large slider 135 slide vertically.

[0104] Furthermore, the pull belt mechanism 13 adopts the existing mature zipper belt drive structure. The zipper belt is inserted into the pull belt mechanism 13, and the pull belt mechanism 13 drives the zipper belt to achieve step-by-step conveying, and each time it advances by the length of one zipper segment.

[0105] The implementation principle of this application is as follows: when installing the zipper tape, the continuous and uncut zipper tape (which is connected in sequence with multiple independent zipper segments) is passed through the guide frame 40, the installation mechanism 12, the feeding mechanism and the zipper tape mechanism 13 in sequence.

[0106] During installation, the upper stop 17 is engaged in the positioning slot 8 by the feeding mechanism described in Example 1. The hook body 126 is driven by the fifth driving member 143 to extend out of the chain groove 14. With the help of the inclined guide structure of the guide angle part 1271 at the front end of the hook, the baffle 127 is guided to smoothly and steadily pass between the two sides of the zipper tape, so that the two sides of the tape are naturally placed on the left and right sides of the baffle 127, separating the two sides of the tape. The fabric pressure plate 130 is driven by the fourth driving member 128 to move in the vertical direction. The pin 133 and the insertion port 16 are interlocked. At the same time, the pressing part 1301 of the fabric pressure plate 130 and the hook clamp and fix the zipper tape, which can prevent the two sides of the tape from lifting or flipping, and pre-press the zipper tape, providing stable support for the subsequent installation process of the upper stop 17, ensuring the stability of the zipper tape posture and reliable positioning.

[0107] Subsequently, the sixth driving component drives the hook body 126 to approach the fork stop bar 124. Since the pin 133 is inserted into the insertion port 16, it drives the fabric pressure plate 130 and the fabric pressure slider 132 to slide, simultaneously driving the zipper tape of the separated fabric tape on both sides to approach the fork stop bar 124. Then, the second driving component 138 drives the fork stop bar 124 to pass through the forming seat 123, so that the fork stop bar 124 can accurately extend into the fabric tape on both sides of the zipper tape. The two third driving components 139 drive the two pusher sliders 125 to move in opposite directions, pushing the fabric tape on both sides of the zipper tape in the direction of approaching each other. After being blocked by the fork stop bar 124, the fabric tape on both sides gradually tightens along the edge of the fork stop bar 124, making the zipper tape Y-shaped.

[0108] Next, by driving the large slider 135, the positioning seat 5 is brought close to the Y-shaped branch of the zipper tape, allowing the buckle 172 of the upper stop 17 to pass through the zipper tape for installation. Simultaneously, by driving the small slider 137, the punch 136 slides vertically, pushing the upper stop 17 out of the positioning slot 8, releasing the upper stop 17 from the positioning slot 8, thus allowing the upper stop 17 to completely detach from the positioning slot 8 and remain smoothly on the zipper tape. At this point, guided by the guide groove 27, the four buckles 172 of the upper stop 17 bend correctly, thus securing the upper stop 17 to the Y-shaped branch of the zipper bag. After completion, the large slider 135 and small slider 137 are reset.

[0109] Finally, all components are reset, and the zipper pull mechanism 13 drives the zipper belt forward by one zipper segment length. The feeding mechanism then feeds the zipper belt again, allowing for the next round of installation. This achieves fully automated and stable processing of the zipper belt from separation, pre-compression, Y-forming to installation and fastening at the top stop 17. The process is smooth, the positioning is precise, and the finished product quality is consistent, significantly improving production efficiency and yield.

[0110] In summary, through the collaborative design of multiple structures, including step-by-step guiding and separation of the zipper tape, pre-compression to prevent warping, precise Y-shaped forming, and positioning and fastening at the top stop 17, installation errors such as tape folding, misalignment, top stop 17 deviation, and poor bending of the buckle 172 are avoided from the source. While ensuring smooth process connection and accurate and reliable positioning, it can also effectively reduce tape jamming and machine downtime caused by unstable positioning, and reduce the frequency of equipment debugging and maintenance. It can achieve fully automated continuous operation without manual intervention, and ensures that the installation force and fastening shape of the top stop 17 are highly uniform, further improving the neatness of the finished product appearance and the connection firmness, extending the overall service life of the zipper, and adapting to high-speed continuous production lines to achieve high-quality, high-stability, and high-economic large-scale production.

Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention.
