[0044] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.

[0045] Example 1

[0046] The assembling machine disclosed in this embodiment is used to assemble the front part of a double-pull-tab self-locking zipper head. As Figure 1 , 2 shown, this assembling machine includes a machine base 1 and a rotatable turntable 11. A number of station devices 12 are arranged on the turntable 11. An feeding mechanism 2 composed of a slider body feeding mechanism 21, a pull-tab feeding mechanism 22, a hook feeding mechanism 23, and a cap feeding mechanism 24. Each feeding mechanism is used to transfer materials to the corresponding station device 12 for installation; each feeding mechanism is respectively connected to a vibrating bowl 3. The materials are conveyed to the feeding mechanism through the vibrating bowl 3, and the materials are conveyed through the feeding channel; in the vibrating bowl 3 for placing the slider body of this assembling machine, there is a slider alignment mechanism 4. The slider alignment mechanism 4 is used to align the slider body. In this embodiment, for example, through the slider alignment mechanism 4, the slider bodies entering the feeding channel are unified into a state with the front side facing up; a riveting mechanism 5 for riveting the cap and the slider body; a blanking mechanism 8 for blanking the finished zipper head; this assembling machine also has a lifting mechanism 6, which specifically includes a liftable lifting plate 61. The lifting plate 61 is located below the turntable 11. The lifting plate 61 corresponds to the slider body feeding mechanism 21 and the pull-tab feeding mechanism 22. The lifting plate 61 is used to jack up the working device for the feeding and assembling of the slider body and the pull-tab. The feeding and assembling process of this assembling machine is fully automatic without manual intervention, which can effectively improve the production efficiency of the zipper head.

[0047] An inclined feeding plate 31 is provided outside the vibrating bowl 3. A feeding channel is provided inside the feeding plate 31. The materials screened by the vibrating bowl 3 are regularly conveyed to the feeding mechanism through the feeding channel.

[0048] The machine base 1 is a frame structure with a workbench surface. A turntable driving device is provided below the turntable 11. The turntable driving device can be a motor, and this motor is fixed on the workbench surface.

[0049] As Figure 3 shown, the slider alignment mechanism 4 includes a fixed bottom plate 41. The fixed bottom plate 41 is fixed in the vibrating bowl 3. The fixed bottom plate 41 is connected to the feeding channel of the vibrating bowl 3. An arc-shaped sorting boss 42 is provided on the fixed bottom plate 41. Baffle plates 43 are respectively provided at both ends of the sorting boss 42. A guiding inclined surface 421 is provided at the feeding end of the sorting boss 42. Grooves with different depths are provided on the front and back sides of the slider body. The height of the sorting boss 42 is the same as the depth of the deepest groove in the slider body. When the shallower groove cooperates with the sorting boss 42, the slider body will fall back into the vibrating bowl 3 during the vibrating transfer process of the vibrating bowl 3. Through the above process, it is ensured that the front and back orientations of the slider body are consistent before feeding.

[0050] As Figure 16 , 17As shown, the station devices 12 are evenly distributed on the edge of the turntable 11. The station devices 12 are mainly used for clamping the slider body and transporting the slider body to subsequent assembly mechanisms through the rotation of the turntable 11. The station device 12 includes a station positioning seat 121 fixed on the turntable 11. A swing groove 1211 is provided on the station positioning seat 121. The swing groove 1211 can penetrate the entire station positioning seat 121. A pressing seat 122 is rotatably connected in the swing groove 1211. A first return spring 123 is provided between the turntable 11 and the pressing seat 122. A pressing piece 124 is fixed on the pressing seat 122. The first spring provides rotational potential energy for the pressing seat 122, so that the pressing piece 124 has a force to press the slider body. A top block 125 is connected below the pressing piece 124. The top block 125 penetrates the swing groove 1211. A roller 126 is rotatably connected to the bottom end of the top block 125. When the roller 126 contacts the lifting plate 61, the frictional resistance can be reduced. When the lifting plate 61 moves upward, the pressing piece 124 is pushed upward through the top block 125, so that the gap between the pressing piece 124 and the station positioning seat 121 increases, facilitating the installation of the slider body onto the station positioning seat 121. An installation relief groove 1241 is further provided at the front end of the pressing piece 124, and subsequent materials can be installed onto the slider body through the installation relief groove 1241.

[0051] As Figure 5 , 6As shown in the figure, the slider body feeding mechanism 21 includes a slider feeding block 211 that can slide along the feeding plate 31 and a slider feeding seat 212 fixed to the machine base 1. The rear end of the slider feeding block 211 is connected to a slider feeding cylinder 213, and the slider feeding cylinder 213 is fixed to the feeding plate 31. The inner side of the slider feeding seat 212 is rotatably connected to a slider clamping block 214. A slider feeding channel 2141 is provided through the slider clamping block 214. During the feeding process, the slider feeding channel 2141 is arranged opposite to the feeding channel, and the two are kept connected. The slider body is pushed from the feeding channel into the slider feeding channel 2141 by the slider feeding block 211. The slider clamping block 214 is fixedly connected to one end of a linkage rod 215. The other end of the linkage rod 215 is connected to a control rod 216 that can move up and down reciprocally. When the control rod 216 moves downward, the linkage rod 215 swings downward under the action of gravity, and at the same time drives the slider clamping block 214 to swing until the slider feeding channel 2141 moves to a horizontal state. Specifically, a bearing is provided at the end of the linkage rod 215, and the bearing is kept in contact with the control rod 216 to achieve linkage. A feeding push piece 217 is slidably connected to the slider feeding seat 212. One end of the feeding push piece 217 is connected to a feeding push cylinder 218. The movement of the feeding push piece 217 pushes the slider body from the slider feeding channel 2141 to the working station device 12. Specifically, the feeding of the slider body includes three steps: the slider feeding block 211 pushes the slider body downward, the slider clamping block 214 drives the slider body to rotate, and the feeding push piece 217 pushes the slider body onto the working station device 12.

[0052] Meanwhile, an upper feeding control board 219 is provided above the slider feeding seat 212. A number of controllable needles 2191 that can cycle and expand and contract are provided on the upper feeding control board 219. The controllable needles 2191 are located on one side of the feeding channel. When the controllable needles 2191 extend, they can prevent the slider body in the feeding channel from falling, so as to realize the orderly falling of the slider body and avoid the accumulation or dropping of the slider body. Specifically, the controllable needles 2191 are fixedly connected to a strip-shaped block with an arc-shaped end. The strip-shaped block is slidably connected to a controllable needle base 2191. A lifting rod with a trapezoidal notch is slidably connected to the controllable needle base 2191. The lifting rod reciprocates up and down through a cylinder. When the trapezoidal notch fits with the strip-shaped block, the controllable needles 2191 retract, and vice versa, the controllable needles 2191 extend. The controllable needles 2191 are arranged vertically.

[0053] As Figure 7 、 8As shown, the pull-tab feeding mechanism 22 includes a pull-tab feeding seat 221 fixed on the machine base 1 and a liftable pull-tab lower pressing plate 226, the pull-tab lower pressing plate 226 is lifted and lowered by a cylinder, a pull-tab feeding seat 222 is slidably connected to the pull-tab feeding seat 221, one end of the pull-tab pushing seat 222 is connected to a pull-tab pushing cylinder 223, an upwardly tilted pull-tab abutting piece 224 and a pull-tab fixing block 225 are provided on the pull-tab pushing seat 222, and the front end of the pull-tab fixing block 225 is provided with mutually staggered transversely arranged A clamping groove 2251 and a longitudinally arranged abutment and yielding groove 2252, the front end of the pull-tab abutment piece 224 is provided with an abutment and yielding groove 2252, and the front end portion of the pull-tab fixing block 225 is arranged in the abutment and yielding groove 2252, so that the pull-tab fixing block 225 and the pull-tab abutment piece 224 form a partially staggered position relationship, and the pivot of the pull tab is clamped between the clamping groove 2251 and the pull-tab abutment piece 224, and the pull-tab abutment piece 224 and the pull-tab fixing block 225 are pushed toward the workstation device 12 together through the pull-tab pushing seat 222. Before the pull tab is loaded, the clamping plate 124 in the work station device 12 should be tilted upward under the action of the lifting plate 61. After the pull tab enters the predetermined position, the pull tab lower pressure plate 226 descends until it passes through the abutment and clearance groove 2252 and presses the pull tab to the slider body. Then the pull tab fixing block 225 and the pull tab abutment plate 224 retract, and the clamping plate 124 presses down to press the pull tab and the slider body. The pull tab lower pressure plate 226 rises to its original position. At this time, the installation of the pull tab is completed.

[0054] like Figure 11 , 12As shown in the figure, the cap feeding mechanism 24 includes a cap feeding base 241 fixed to the machine base 1. A longitudinally adjusting groove 2411 and a laterally adjusting groove 2412 that communicate with each other are provided in the cap feeding base 241. A cap synchronization block 242 is slidably connected in the longitudinally adjusting groove 2411. A cap ejecting block 243 and a cap anti - detachment block 244 are slidably connected in the laterally adjusting groove 2412. An anti - detachment extension 2441 is provided on the cap anti - detachment block 244, and the anti - detachment extension 2441 abuts against the cap ejecting block 243. A blanking slot 2431 is provided on the cap ejecting block 243. Part or all of the cap ejecting block 243 is surrounded by the cap anti - detachment block 244 and the anti - detachment extension 2441. The cap ejecting block 243 is linked with the cap synchronization block 242. When the cap synchronization block 242 moves downward, the cap ejecting block 243 is pushed outwards until the blanking slot 2431 is completely aligned with the feeding channel in the feeding plate 31. At this time, the cap in the feeding channel can enter the blanking slot 2431. To make the ejection process smoother, a top - out inclined surface is provided at the end of the cap synchronization block 242, and the top - out inclined surface cooperates with the cap ejecting block 243. A second return spring 245 is provided between the cap anti - detachment block 244 and the cap feeding base 241. When the cap ejecting block 243 moves outwards, it pushes the cap anti - detachment block 244 to move outwards synchronously. At this time, the second return spring 245 deforms. When the cap synchronization block 242 rises, the second return spring 245 pushes the cap anti - detachment block 244 and the cap ejecting block 243 back to their original positions. A liftable driving block 56 is fixed above the cap synchronization block 242. A cap feeding cylinder is connected to the driving block 56. At the same time, a cap feeding piece 247 is fixed to one side of the driving block 56. The cap feeding piece 247 and the cap synchronization block 242 rise and fall simultaneously. The cap feeding piece 247 descends until it extends into the blanking slot 2431, and the cap is pressed into the pull - head body through the cap feeding piece 247.

[0055] Referring to Figure 9 、 10 As can be seen, the structural operating principle of the hook feeding mechanism 23 is the same as that of the cap feeding mechanism 24. Specifically, the hook synchronization block 231 and the hook feeding piece 234 move downward simultaneously. The hook synchronization block 231 pushes the internal hook ejecting block 232 to move outwards, and the hook is pressed into the pull - head body through the hook feeding piece 234. The difference is that the hook anti - detachment block 233 remains fixed. No blanking slot 2431 is provided on the hook ejecting block 232. At the same time, a hook pressing block 2331 is slidably connected to the hook anti - detachment block 233. A fourth return spring 2332 is provided between the hook pressing block 2331 and the hook anti - detachment block 233. The hook is fixed through the clamping cooperation between the hook pressing block 2331 and the hook ejecting block 232. It should be noted that during actual installation, the installation step of the hook is before the installation of the cap.

[0056] As shown in the figure, the riveting mechanism 5 includes a riveting fixed seat 51 fixed on the machine base 1 and a riveting driving rod 52 that can telescopically move up and down relative to the machine base 1. Two positioning plates 53 are arranged at intervals on the riveting fixed seat 51. A fixing rod 54 is arranged between the two positioning plates. A moving rod 531 is slidably connected to the positioning plate. The moving rod 531 extends into the space between the two positioning plates 53. A riveting block 532 is fixed to the inner end of the moving rod 531. A riveting convex point is arranged at the inner position of the riveting block 532. The two riveting blocks 532 are arranged oppositely. A third return spring 55 is arranged between the moving rod 531 and the positioning plate. Two driving blocks 56 are arranged at intervals on the riveting driving rod 52. The two riveting blocks 532 are arranged between the two driving blocks 56. An abutting inclined surface 561 is arranged on the riveting block 532. The driving block 56 is kept in contact with the abutting inclined surface 561. When the driving block 56 moves upward, under the action of the abutting inclined surface 561, the two riveting blocks 532 move inward simultaneously, and the cap is riveted by the riveting convex point. At this time, the third return spring 55 is compressed. After the riveting is completed, the driving block 56 moves downward, and the third return spring 55 pushes the moving rod 531 and the riveting block 532 to move outward synchronously.

[0057] As Figure 15 shown, the blanking mechanism 8 includes a blanking fixed seat 81 fixed on the machine base 1. A blanking moving rod 82531 is slidably connected to the blanking fixed seat 81. The blanking pull head is arranged at the end of the blanking moving rod 82531. The other end of the blanking moving rod 82531 is connected to a blanking driving cylinder 83. The assembled pull head body is taken down from the station device 12 by the blanking pull head and falls into the receiving port on the machine base 1. A lower waste material mechanism 7 with the same structure as the blanking mechanism 8 is also arranged on the machine base 1. The lower waste material mechanism 7 is arranged between the cap feeding mechanism 24 and the riveting mechanism 5. A detection mechanism is connected to each feeding mechanism. The detection structure may be located above the feeding mechanism or on one side of the feeding structure. The detection mechanism will detect the product after each feeding step. The lower waste material mechanism 7 will take down the unqualified products from the station device 12 in advance. The reason for setting it in front of the riveting mechanism 5 is to facilitate the disassembly of the unqualified products and put them back into production to avoid waste of materials.

[0058] As Figure 18As shown in the figure, a power device 13 is provided below the machine base. The power device 13 includes a main drive shaft 131 and a secondary drive shaft 132 that are rotationally connected to the machine base.

[0059] Embodiment 2

[0060] The assembly machine disclosed in this embodiment is used to assemble the reverse side of a double-pull-tab self-locking zipper head. At this time, the front part of the pull tab body has been installed by machine or manually. Since there are already pull tabs and cap covers on the pull tab body, the pull tab body positioning mechanism 4 in this embodiment is different from that in Embodiment 1. Other components such as the pull tab feeding mechanism 22, the hook feeding mechanism 23, the cap cover feeding mechanism 24, the riveting mechanism 5, the discharging mechanism 8, and the lifting mechanism 6 in this embodiment are the same as those in Embodiment 1.

[0061] As Figure 4 shown in the figure, the pull tab body positioning mechanism 4 in this embodiment includes two guide wires 45 arranged at intervals and a blow pipe 46. The guide wires 45 are fixedly connected to the vibrating disk 3. Inclined guide plates 451 are respectively provided at the feeding ends of the two guide wires 45. The discharging end of the inner guide wire 45 is inclined downward. The air outlet of the blow pipe 46 is arranged facing the feeding end of the guide wire 45. A stable feeding state is that the front side of the pull tab body faces downward, the pull tabs are located between the two guide wires 45, and the end of the pull tab body with the chain separating plate is at a lower position. If any of these three positional relationships does not meet the requirements, the pull tab body will fall back into the vibrating disk 3 during the movement along the guide wire 45. The airflow blown by the blowing pipe pushes the pull tab body to move along the guide wire 45, preventing the pull tab body from piling up.

[0062] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
