Technical Field

[0001] The utility model belongs to the technical field of zipper assembly equipment and relates to a zipper head assembly device. Background Art

[0002] A zipper is a connector widely used in clothing and luggage, and is mainly composed of a cloth tape, chain teeth, a zipper head, a pin and a socket. Among them, the zipper head usually adopts an elephant trunk zipper head, which mainly includes a slider and a pull tab, and the slider and the pull tab are assembled by riveting. The structure of the existing zipper head assembly device is relatively complex. For example, the Chinese patent application (application number: 202120287131.8) discloses an elephant trunk zipper head assembly machine, which includes an assembly machine base, an assembly machine transmission part is provided in the base, and a turntable, a slider vibration disk, an adjustable elephant trunk slider runway, a zipper clamping device, a triangular piece riveting device, and a discharge device are provided on the upper panel of the base. The zipper head is assembled through precise coordination of each station. However, the power sources of the various stations of the existing zipper head assembly machine are mostly independent of each other, and the stations are coordinated through electronic control. The mutual correlation and synchronization coordination are poor, which can easily lead to the misalignment of the working frequency, resulting in inability to cooperate and the occurrence of waste. Summary of the Invention

[0003] The purpose of the present invention is to solve the above problems in the existing technology and to propose a zipper head assembly device. The technical problem to be solved by the present invention is: how to improve the synchronization and coordination of each station of the zipper head assembly device.

[0004] The purpose of the utility model can be achieved through the following technical solutions: A zipper head assembly device, including a frame, a power source, a slider runway, a slider vibration plate for conveying the slider to the slider runway, a pull tab runway, and a pull tab vibration plate for conveying the pull tab to the pull tab runway, characterized in that it also includes: an assembly runway located on the frame, for receiving the slider and pull tab conveyed by the slider runway and the pull tab runway;

[0005] Slider opening and closing mechanism, used to open and close the slider runway;

[0006] Pull tab opening and closing mechanism, used to open and close the pull tab runway;

[0007] Feeding mechanism, used to push the pull head on the assembly runway forward;

[0008] The clamping mechanism is used to cooperate with the feeding mechanism to clamp and fix the slider;

[0009] Riveting mechanism, used for punching and riveting the trunk of the slider;

[0010] The slider opening and closing mechanism, the pull tab opening and closing mechanism, the feeding mechanism, the clamping mechanism and the riveting mechanism are all transmission-connected to the power source and are only powered by the power source.

[0011] The slider opening and closing mechanism, the tab opening and closing mechanism, the feeding mechanism, the clamping mechanism, and the riveting mechanism of the utility model are all powered by the same power source. During the assembly process, the slider is transported to the slider runway by the slider vibrating disk, and the tab is transported to the tab runway by the tab vibrating disk. The slider and the tab move to the front ends of the slider runway and the tab runway under the action of gravity. Then, the slider opening and closing mechanism opens the slider runway, allowing a slider to slide into the assembly runway. The feeding mechanism then pushes the slider forward. When the slider moves below the tab runway, the tab opening and closing mechanism opens the tab runway, allowing a tab to fall and form a connection with the slider's trunk. The feeding mechanism continues to push the slider forward and positions the slider directly below the riveting mechanism. Driven by the power source, the clamping mechanism also moves toward the slider and clamps the slider in tandem with the feeding mechanism. The riveting mechanism then moves downward and presses the slider's trunk to connect the tab to the slider. Throughout the entire process, all mechanisms are coordinated through mechanical transmission, making the entire assembly process more stable and precise.

[0012] In the aforementioned zipper pull assembly device, a rotating shaft 1 is provided on the frame, which is transmission-connected to a power source. The slider opening and closing mechanisms and the pull tab opening and closing mechanisms have the same structure, both comprising a cam 1, a slider 1, and a baffle. The cam 1 is disposed on the rotating shaft 1, and the slider 1 is disposed above the cam 1 and can move up and down under the rotation of the cam 1. The baffle is fixedly connected to the slider 1 and is located at the exit of the slider runway or the pull tab runway. The rotating shaft, through the cooperation of the cam 1 and the slider 1, can drive the baffle to move up and down to open and close the slider runway and the pull tab runway.

[0013] In the aforementioned zipper pull assembly device, the feeding mechanism includes a second cam, a rocker, a spring seat, and a first push rod. The rocker is vertically arranged with its lower end hinged to the frame. The second cam is mounted on the first rotating shaft and is used to push the rocker to swing to one side. The spring seat is fixed to the frame along the length of the assembly track. The spring seat contains a spring for driving the rocker to swing to the other side. The first push rod is arranged at the rear side of the assembly track along the length of the assembly track and is fixed to the upper end of the first push rod. When the rotating shaft rotates, the rocker, in cooperation with the second cam and the spring, can drive the first push rod to move forward and backward.

[0014] In the aforementioned zipper head assembly device, the clamping mechanism includes a second rotating shaft, a third rotating shaft, a cam plate, a second slider, and a second push rod. The second slider is slidably mounted on the frame along the length of the assembly track and is located at the front of the assembly track. The second rotating shaft is arranged parallel to the first rotating shaft and connected via a belt drive. The third rotating shaft is arranged perpendicular to the second rotating shaft and is connected to the second rotating shaft via a bevel gear pair. The cam plate is connected to the third rotating shaft and is used to drive the second push rod to move forward and backward along the length of the assembly track. The second push rod is opposite the first push rod, and through the cooperation between the second push rod and the first push rod, the slider can be clamped and fixed forward and backward.

[0015] In the aforementioned zipper pull assembly device, the riveting mechanism includes a crank, an eccentric wheel, a third slider, and a punch. The eccentric wheel is fixed to the first rotating shaft. One end of the crank is rotatably connected to the eccentric wheel. The third slider is slidably mounted above the crank and hinged to the other end of the crank. The punch is fixed to the third slider and located directly above the assembly track. Through the cooperation of the eccentric wheel, crank, and slider, the rotation of the first rotating shaft drives the punch to move up and down, punching and riveting the trunk of the slider.

[0016] In the above-mentioned zipper head assembly device, a hand wheel is further provided at one end of the rotating shaft 1. The provision of the hand wheel enables a person to manually adjust the angle of the rotating shaft 1, facilitating later adjustment.

[0017] In the above-mentioned zipper head assembly device, a discharge hopper is provided just below the front end of the assembly track.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] 1. In the present invention, the slider opening and closing mechanism, the pull tab opening and closing mechanism, the feeding mechanism, the clamping mechanism, and the riveting mechanism are all connected to the power source, so that the above mechanisms can form a stable coordinated cooperation, the cooperation between the mechanisms is more precise and stable, the assembly is more stable and reliable, and the yield rate is higher.

[0020] 2.

DETAILED DESCRIPTION

[0028] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0029] A zipper head assembly device, such as Figure 1 As shown, the assembly includes a frame 1, a power source 2, a slider track 33, a slider vibration plate 31, a tab track 34, a tab vibration plate 32, an assembly track 11, a slider opening and closing mechanism 4a, a tab opening and closing mechanism 4b, a feeding mechanism 5, a clamping mechanism 6, and a riveting mechanism 7. The power source 2 is in transmission connection with the slider opening and closing mechanism 4a, the tab opening and closing mechanism 4b, the feeding mechanism 5, the clamping mechanism 6, and the riveting mechanism 7, so that each of the aforementioned mechanisms is powered solely by the power source 2, thereby ensuring coordinated cooperation among the aforementioned mechanisms.

[0030] Specifically, such as Figure 1As shown, the slider vibration plate 31, the tab vibration plate 32, the slider runway 33, the tab runway 34 and the assembly runway 11 are all arranged on the table top of the frame 1, wherein the slider vibration plate 31 and the tab vibration plate 32 are used to transport the slider and the tab to the slider runway 33 and the tab runway 34 respectively, the slider runway 33 and the tab runway 34 are both inclined, and the assembly runway 11 is horizontally arranged on the table top, the tab runway 34 and the slider runway 33 are both located above the assembly runway 11 and their lower ends are both facing the assembly runway 11, and at the same time, the tab runway 34 is located in front of the slider runway 33, so that the slider runway 33 falls into the assembly runway 11, and when the slider moves forward to the bottom of the tab track, the tab falls into the assembly runway 11 and forms a match with the slider. Figure 2 、 Figure 3 、 Figure 5 As shown, in this embodiment, the power source 2 is a drive motor. The frame 1 is provided with a rotating shaft 8, which is connected to the drive motor via a belt drive. The slider opening and closing mechanism 4a and the tab opening and closing mechanism 4b have the same structure, each comprising a cam 41, a slider 42, and a baffle 43. Cam 41 is fixedly mounted on cam 41, and slider 42 is vertically positioned above cam 41 and can slide up and down relative to the frame 1. Slider 42 is provided with a roller at its lower end and abuts against cam 41 via the roller. Baffle 43 is fixedly connected to slider 42, so that when rotating shaft 8 drives cam 41 to rotate, slider 42 and baffle 43 can be driven up and down. Baffle 43 of the slider opening and closing mechanism 4a is located at the exit of the slider runway 33, while baffle 43 of the tab opening and closing mechanism 4b is located at the exit of the tab runway 34, so that when baffle 43 moves up and down, it opens or closes the exit of the slider runway 33 or the tab runway 34.

[0031] like Figure 2 、 Figure 3 、 Figure 5 As shown, the feeding mechanism 5 includes a cam 2 52, a rocker 51, a spring seat 53 and a push rod 1 54, wherein the cam 2 52 is fixed on the rotating shaft 1 8, the rocker 51 is vertically arranged and the lower end of the rocker 51 is hinged to the frame 1 through a ball joint, the spring seat 53 is arranged along the length direction of the assembly runway 11 and is fixed relative to the frame 1, a spring is arranged in the spring seat 53 and the two ends of the spring are respectively abutted against the spring seat 53 and the upper end of the rocker 51, the push rod 1 54 is arranged along the length direction of the assembly runway 11 and is fixed to the upper end of the rocker 51, and a roller is further provided on one side of the rocker 51 and abuts against the cam 2 52 through the roller, so that when the rotating shaft 1 8 rotates, the rocker 51 can swing back and forth under the action of the cam 2 52 and the spring, thereby driving the push rod 1 54 to move back and forth along the length direction of the assembly runway 11.

[0032] like Figure 4 、 Figure 5As shown, the clamping mechanism 6 includes a second rotating shaft 61, a third rotating shaft 64, a cam plate 65, a second slider 66 and a second push rod 67, wherein a pulley 62 is provided on the rotating shaft 8, the second rotating shaft 61 is arranged relatively parallel to the rotating shaft 1 8 and a pulley 2 63 is provided at one end of the rotating shaft 2 61, and the pulley 1 62 and the pulley 2 63 are connected by a belt transmission, the rotating shaft 3 64 is arranged vertically relative to the rotating shaft 2 61 and the other end of the rotating shaft 2 61 is connected to the lower end of the rotating shaft 3 64 by a bevel gear pair, and a cam guide is provided on the cam plate 65 and The second slider 66 is fixedly connected to the upper end of the rotating shaft 3 64 and can be slidably arranged on the frame 1 along the length direction of the assembly runway 11 and is located on the front side of the assembly runway 11. The rear end of the slider 2 66 is provided with a pulley that slides with the cam guide rail on the cam plate 65. The push rod 2 67 is connected to the slider 2 66 so that when the rotating shaft 1 8 drives the cam plate 65 to rotate, the push rod 2 67 can be driven to move back and forth along the length direction of the assembly runway 11. In this way, the pull head in the assembly runway 11 can be clamped and fixed front and back through the cooperation between the push rod 2 67 and the push rod 1 54.

[0033] like Figures 4-6 As shown, the riveting mechanism 7 includes a crank 72, an eccentric wheel 71, a slider three 73 and a punching head 74. The eccentric wheel 71 is fixed on the rotating shaft 8. The slider three 73 is vertically arranged above the eccentric wheel 71 and can move up and down relative to the frame 1. The punching head 74 is fixedly connected to the slider three 73 and is located directly above the assembly runway 11. One end of the crank 72 is rotatably connected to the eccentric wheel 71 and the other end is hinged to the lower end of the slider three 73, so that the rotating shaft 8 can drive the slider three 73 and the punching head 74 to move up and down.

[0034] like Figure 4 As shown, in this embodiment, a discharge hopper 9 and a sensor are further provided at the front end of the assembly runway 11. The discharge hopper 9 is located below the assembly runway 11. The discharge hopper 9 has two discharge ports, one of which is an outlet for qualified products and the other is an outlet for defective products. A control device that communicates with the sensor is also provided in the discharge hopper 9. The sensor can detect whether the pull tab and the pull head are assembled qualified. If qualified, the control device connects the feed port of the discharge hopper 9 to the outlet for qualified products. Otherwise, the controller connects the feed port of the discharge hopper 9 to the outlet for defective products.

[0035] Furthermore, a hand wheel 81 is provided at one end of the rotating shaft 8, and the rotation angle of the rotating shaft 8 can be manually adjusted by the hand wheel 81.

[0036] The working process of the present invention is as follows: the slider vibration plate 31 and the tab vibration plate 32 transport the slider and the tab to the slider runway 33 and the tab runway 34 respectively. Driven by the rotating shaft 8, the slider opening and closing mechanism 4a is opened and closed once, so that a slider falls into the assembly runway 11, and then the top rod 54 of the feeding mechanism 5 moves forward and pushes the slider forward. When the slider moves to the bottom of the tab runway 34, the tab opening and closing mechanism 4b is opened and closed once, so that a tab falls into the assembly runway 11 and is sleeved on the slider's trunk. At this time, the feeding mechanism 5 continues to push the slider forward, and the clamping mechanism 5 is clamped. The second push rod 67 of the mechanism 6 moves toward the first push rod 54, causing the front and rear ends of the slider to abut against the second push rod 67 and the first push rod 54 respectively, and the slider is fixed directly below the punch head 74. At this time, the punch head 74 of the riveting mechanism 7 moves downward and rivets the trunk of the slider, connecting the pull tab and the slider. After the punching is completed, the second push rod 67 retracts, and the assembled slider continues to move forward and passes through the sensor and falls into the discharge hopper 9. If the sensor detects that it is qualified, it slides out of the qualified product outlet of the discharge hopper 9. If the sensor detects that it is unqualified, it slides out of the defective product outlet of the discharge hopper 9. Since the slider opening and closing mechanism 4a, the pull tab opening and closing mechanism 4b, the feeding mechanism 5, the clamping mechanism 6, and the riveting mechanism 7 are all transmission-connected to the rotating shaft 1 8, in this embodiment, one rotation of the rotating shaft 1 8 completes the assembly of the zipper slider.
