[0041] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0042] The present invention relates to a structure and an assembly matching structure of an auxiliary component connected to a slider, such as Figure 8 and Fig. 9 As shown, a slider latch has a structure including a head 10 and two claws 20 extending and protruding from the lower surface of the head. The two claws 20 are symmetrically arranged at a central interval. The claws are divided into an upper section 201 connected to the head 10 and cannot be inserted into the slider 30, and a lower section 202 that can be correspondingly inserted into the slider 30. When in use, the two lower sections 202 are respectively inserted into the cloth seams on both sides of the slider 30, and the ends of the two lower sections 202 extend and protrude outward to form anti-slip convex parts 203 that can hook the slider 30.

[0043] This embodiment discloses a pull head latch assembly machine, such as Figure 1-Figure 7 As shown, it includes a machine base 1, a work station turntable 2, a pull head orientation fixture 3, a feeding device (including a pull head feeding device 41 and a latch feeding device 42), a unloading device (including a pull head unloading device 51 and a latch unloading device 52), a discharging device 6, a sensor detection device 7, etc. The structural position connection relationship of each part is described in detail below in conjunction with the accompanying drawings.

[0044] The machine base 1 is a metal frame structure with a stable structure, and its upper surface is a work surface for installation and support of other mechanical parts and equipment.

[0045] The workstation turntable 2 is a circular turntable mounted on a work surface, and a driving motor is connected to its bottom. A plurality of workstations are evenly spaced along the circumferential edge of the workstation turntable 2. The driving motor drives the turntable 2 to perform indexing rotation so that each workstation performs the corresponding process action in turn.

[0046] The pull head orientation fixture 3 is used to position the pull head for other actions. It is set on each station of the station turntable 2. Considering that a finished pull head has a pull tab, the pull head body has various sizes and specifications, and its pull tab is more diverse, in order to make the pull head orientation fixture adaptable to various pull head positioning uses, the present embodiment is as follows Figure 6As shown, the pull head orientation fixture 3 includes a fixed block 31 fixedly installed on the work station of the work station turntable 2, a pull head positioning groove 32 arranged on the fixed block 31, and a pull head blocking component 33 arranged corresponding to the outer side of the pull head positioning groove 32. The pull head positioning groove 32 is opened on the vertical outer side surface of the fixed block 31 (the side facing the outer side of the circumferential surface of the work station turntable 2) and passes through from top to bottom. The pull head positioning groove 32 is a structural setting in which the upper end opening width is greater than the lower end opening width, so that the pull head can fall into the upper end of the pull head positioning groove 32 and can prevent it from falling from the lower end. The pull head positioning groove 32 shown in the figure is a shape corresponding to the outer contour of both sides of the pull head, and can also better limit the pull head. The slider blocking component 33 is used to limit the slider to remain embedded in the slider positioning groove 32 without falling out, and at the same time cannot affect the normal entry of the slider into the slider positioning groove 32. The structure disclosed in this embodiment is a relatively simple and particularly practical structure. The slider blocking component 33 is a transverse round rod, which is perpendicular to the upper and lower ends of the slider positioning groove 32, directly corresponding to the outer side of the slider positioning groove 32, and its surface is an arc surface, which has an introduction function and will not cause the problem of the slider being stuck and unable to enter the slider positioning groove 32. It can also be further provided with a roller on the transverse round rod at the position corresponding to the slider positioning groove 32, which can make the introduction of the slider smoother, and can also reduce friction, thereby avoiding scratches on the color layer on the surface of the finished slider. The cam 33 is provided with a plurality of holes 35 on the two ends of the cam 33 so as to be able to move freely in the cam 33 and adjust the position of the cam 33. The slider orientation fixture 3 of the above-mentioned structural arrangement is not only simple in structure, easy to manufacture, easy to assemble and debug, but also has good basic use functions and applicability.

[0047] The feeding device and the unloading device are installed on the machine base 1. The slider feeding device 41 and the latch feeding device 42 are respectively used for uniformly oriented and orderly conveying the sliders and latches one by one, usually by means of vibration feeding. The input end of the slider unloading device 51 is connected to the output end of the slider feeding device 41, and the input end of the latch unloading device 52 is connected to the output end of the latch feeding device 42, so as to realize the conveying of the sliders and latches to the assembly stations one by one.

[0048] The pull head blanking device 51, the pin blanking device 52 and the discharging device 6 are arranged around the work station turntable 2 in sequence, and the sensor detection device 7 is respectively arranged around the work station turntable 2 between the pull head blanking device 51 and the pin blanking device 52, between the pin blanking device 52 and the discharging device 6, and between the discharging device 6 and the pull head blanking device 51. In this way, through the rotation of the work station turntable 2, each pull head orientation fixture 3 thereon can correspond to the discharging end of the pull head blanking device, the output end of the pin blanking device, the output end of the discharging device and the detection of each sensor detection device 7 one by one, so that the mechanical work can perform effective assembly actions. The setting of the sensor detection device 7 here can also be increased or removed according to the needs of actual conditions.

[0049] The structures of the slider unloading device 51 and the latch unloading device 52 disclosed in this embodiment are similar, and mainly include a unloading bracket 53, a unloading chute 54, a push arm 55, an unloading drive cylinder 56 and a push block 57. The lower end of the unloading bracket 53 is fixedly connected to the work surface, and the unloading chute 54 is vertically fixedly mounted on the unloading bracket 53, and a slideway 541 is provided along the length direction to prevent the slider or the latch from being separated. The upper end of the slideway 541 is the input end of the slider unloading device 51 connected to the output end of the slider feeding device 41 or the input end of the latch unloading device 52 connected to the output end of the latch feeding device 42, as shown in the corresponding connection in the figure, and the lower end of the slideway 541 is the discharge end 542 of the slider or the latch that can correspond to the slider positioning groove 32. The discharge end 542 is provided with a first elastic material stopping structure 581 and a second elastic material stopping structure 582 which are spaced apart from each other. The first elastic material stopping structure 581 is used at the top to block the sliders or latches that are neatly arranged and fed in, so that the bottom slider or latch can be unloaded. The sliders or latches above will not continue to slide down and affect the unloading action. The second elastic material stopping structure 582 is used to block the sliders or latches to avoid the situation of sliding down directly, but to unload the materials through a unloading action one by one. The unloading drive cylinder 56 is installed on the unloading bracket 53, and its piston rod is connected to the upper end of the vertically arranged pushing arm 55. The pushing arm 55 is slidably connected to the unloading bracket 53 through a vertical sliding guide structure to achieve smooth directional sliding. One end of the pushing block 57 is connected to the lower end of the pushing arm 55, and the other end thereof corresponds to the sliding channel 541. The action of the unloading drive cylinder 56 drives the pushing arm 55 to rise and fall, and at the same time drives the pushing block 57 to push the pull head or the pin to slide through the first elastic material blocking structure 581 and the second elastic material blocking structure 582 to realize the unloading activity.

[0050] Here, the push block is not simply capable of achieving the action of pushing down, but it cannot drive other pull heads or latches to rise back to their original positions to perform the next pull head or latch unloading action when it rises. Therefore, here, the push block 57 needs to be connected to the lower end of the push arm 55 through a push reset structure. The push reset structure is as follows: the lower end of the push arm 55 is provided with a mounting groove 551, and the upper top surface of the mounting groove 551 is an inclined surface 552 inclined downward toward the slide channel 541. One end is hinged in the installation groove 551 through a pin shaft 553, and a tension spring 557 is provided between the end of the push block 57 on one side of the pin shaft 553 and the inclined surface 552, and the upper surface of the push block on the other side of the pin shaft 553 is pressed against the lower edge of the inclined surface 552. The other end of the push block 57 is a U-shaped fork corresponding to the two ends of the upper side surface of the pull head or the pin in the slide channel 541, and the corresponding discharge end 542 on the unloading slide channel 54 is provided with an upper and lower sliding groove 543 for the U-shaped fork to pass through and embed into the slide channel 541. Through the above-mentioned structural setting, when the push arm 55 rises, the structural setting of the inclined surface 552 provides a rotatable space for the push block 57. When rising, the U-shaped fork hits the pull head or latch of the slide channel 541, and the resistance is relatively large, so the push block 57 can be easily rotated back to the original position without pushing the pull head or latch upward. When descending, the two ends of the U-shaped fork are stuck at the two ends of the upper side of the inner pull head or latch. When descending, the upper surface of the push block 57 presses against the lower edge of the inclined surface 552, and the push block 57 cannot rotate when the push arm 55 descends, so it can push the pull head or latch to slide down and discharge the material. In this embodiment, Figure 5 The upper end of the upper and lower sliding grooves 543 shown in the figure is provided with a blocking block 544 for pushing the U-shaped fork to rotate downward, and the blocking block 544 and the U-shaped fork are provided with relatively matching inclined guide surfaces 554. This structural setting can better push the U-shaped fork to rotate and reduce the wear caused by friction between the U-shaped fork and the surface of the pull head when the U-shaped fork rises.

[0051] In actual use, there are situations where individual pull tabs affect detection, individual pull tabs are large and cause abnormal noise, or are easily worn. In order to reduce the occurrence of these situations, the slider unloading device 51 in this embodiment is also provided with a blowing device having a blowing pipe 591. The air outlet end of the blowing pipe 591 is arranged at the outside of the discharge end 542 on one side of the pull tab when the slider slides down the slide channel 541, and air is blown at an inclined downward angle. When the slider is pushed down into the slider positioning groove 32, air is blown at the same time. This can keep the pull tab on the slider downward and pass through the slider positioning groove 32 together without being stuck above the horizontal round rod.

[0052] The first elastic material blocking structure 581 and the second elastic material blocking structure 582 respectively include a movable hole 583 opened on the side wall of the sliding channel 541, a material blocking arm 584 inserted in the movable hole 583 and an elastic connecting piece 585 elastically supporting the inner end of the material blocking arm 584 protruding from the inner wall of the sliding channel 541, and the inner end of the material blocking arm 584 is an end structure that facilitates the pull head or the pin to slide from top to bottom and guide the unloading of the material left and right, as shown in the structure in the figure. In addition, due to the structural characteristics of the latch component, in order to prevent the latch from being deflected to the front, back, left, and right during the blanking process, which may result in the inability to align and insert the latch onto the slider, the latch blanking device 52 described in this embodiment is provided with a guide block 586 at the inner end of a blocking arm 584 corresponding to the first elastic blocking structure 581 and the second elastic blocking structure 582 on the side opposite to the push block 57, which is used to guide the latch forward and backward when blanking, and the spacing distance between the inner end of the blocking arm 584 and the slider orienting fixture 3 is set to a height that is conducive to the slider or latch being able to be aligned and inserted.

[0053] The discharging device 6, as shown in the figure, includes a discharging chute 61, a pushing mechanism (not visible from the perspective of the figure) corresponding to the bottom of the slider positioning groove 32 for pushing the lower end of the latch so that the slider exits the slider positioning groove 32, and a blowing device (not visible in the figure) having a blowing nozzle (not visible in the figure) for blowing the slider exiting the slider positioning groove 32 into the entrance end of the discharging chute 61. The setting of the sensor detection device 7 can realize the detection of the pull head, the latch and the assembly status of the two. If there is no problem in the detection, the assembly is qualified, and if there is a problem, it is unqualified. In order to distinguish qualified and unqualified materials, the discharge chute 61 described in this embodiment includes a finished product chute 611, a defective chute 612 and a defective guide plate 613. The side wall of the finished product chute 611 is provided with a channel opening 614 corresponding to the entrance end of the defective chute 612. The defective guide plate 613 is connected to a driving flipping mechanism 615 for driving its flipping action. The flipping of the defective guide plate 613 can achieve the connection of one of the finished product chute or the defective chute. Specifically, the action of the driving flipping mechanism 615 is controlled according to the detection structure of the sensor detection device 7 to achieve the distinction and discharge.

[0054] The sensing detection device 7 is shown in the figure, which is arranged around the station turntable 2 between the slider feeding device 51 and the latch feeding device 52, between the latch feeding device 52 and the discharging device 6, and between the discharging device 6 and the slider feeding device 51. Through the rotation of the station turntable 2, each sensing detection device 7 can detect whether there is a slider or a latch on each slider orientation fixture 3. In the structure of this embodiment, the sensing detection device 7 arranged between the slider feeding device 51 and the latch feeding device 52, and between the latch feeding device 52 and the discharging device 6 is a distance sensing detection device, and the sensing detection device 7 between the discharging device 6 and the slider feeding device 51 is different from the previous two, because this part indicates that there is an object in the slider positioning groove 32 when there is a problem with the detection, then it is impossible to continue the feeding of the next slider, and a cleaning process is required. Therefore, the sensing detection device 7 between the discharging device 6 and the slider feeding device 51 in this embodiment includes A fixed mounting rod 71 and a toggle sensor 73 with a toggle rod 72 are fixedly mounted at the lower end. The toggle rod 72 corresponds to the top of the pull head orientation fixture 3. The height is set at a height at which the toggle rod 72 can be toggled by the plug pull head when there is still a pull head with a pin inserted in the pull head positioning groove 32. In this way, when there is still a pull head on the pull head orientation fixture 3, the toggle rod 72 will be touched when the work station turntable 2 rotates, triggering the sensor detection device 7 to remind that there is a pull head that needs to be processed. At this time, the pin assembly machine can be controlled to temporarily operate, the work station turntable 2 stops rotating, and the pull head of the pull head orientation fixture 3 is manually cleaned. In order to facilitate manual cleaning of the pull head, in this embodiment, a fixed plate 711 is provided at the upper end of the fixed mounting rod 71, and the toggle sensor 73 is arranged on a movable plate 712. The movable plate 712 is connected to the fixed plate 711 with a flip structure that can be flipped relative to the fixed plate 711. As shown in the figure, the toggle rod 72 is arranged on one side of the toggle sensor 73 and is arranged opposite to the rotation direction of the station turntable 2. A rotating shaft is provided on the fixed plate 711, and the movable plate 712 is hinged on the rotating shaft, so that it can be manually flipped and is easy to operate. It needs to be reset after flipping. When the slider is in the locked state, the slider 712 is moved back to its original position, and the slider 712 is reset to its original position. Therefore, an elastic reset structure 713 is also provided between the fixed plate 711 and the movable plate 712. As shown in the figure, a spring is connected between the fixed plate 711 and the movable plate 712, and a reset limit component 714 is provided on the fixed plate 711. The spring is stretched when flipping, and the spring elastic force retracts when releasing the flipping to pull the movable plate 712 to flip back. When it contacts the reset limit component, it is stuck and the reset is completed. Through this structural setting, when the slider is stuck by the toggle rod 72, the toggle rod 72 can be flipped open through the above structure to remove the slider.

[0055] The slider pin assembly machine of the above structure of the present invention, when working, the slider feeding device conveys the slider to the slider unloading device, and the pin feeding device conveys the pin to the pin unloading device. The station turntable indexing rotates continuously, and the slider unloading device discharges a slider into the slider positioning groove according to the rotation time of the station turntable, and the pin unloading device discharges a pin into the slider clamped in the slider positioning groove accordingly, and the discharging device disengages the slider with the pin inserted from the slider positioning groove and discharges it. During this process, the sensor detection device 7 will detect the stations on the station turntable between two adjacent stations. If there is a problem in the detection, a solution will be adopted, and then the subsequent actions will be continued. Or an automatic assembly working method of a slider pin assembly machine of the above mechanical structure of the present invention as disclosed in detail below, the working method steps are as follows,

[0056] 1) The slider feeding device is used to continuously and orderly output the sliders in a uniform direction and enter the slideway of the slider feeding device. The sliders in the slideway of the slider feeding device are as follows: the slider body of the slider is stuck in the slideway, and the pull tab of the slider is suspended outside the slideway. When the slider is used, the front end of the zipper closing operation faces upward.

[0057] The pin feeding device continuously outputs the pins in a uniform and orderly manner and enters the slideway of the pin feeding device. The pins in the slideway of the pin feeding device have their heads facing upwards.
