[0068] The embodiments of the present invention are further described below in conjunction with the accompanying drawings:

[0069] As shown in the figure, a zipper head and pull tab assembly machine includes a frame 1, a rotating worktable 2, a zipper head feeding device, a pull tab feeding device, a riveting device 6, a stripping device 5 and a control system. The zipper head feeding device includes a zipper head vibration plate 9 and a zipper head conveying device 7. The pull tab feeding device includes a pull tab vibration plate 3 and a pull tab conveying device 4. The rotating worktable 2 is provided with a plurality of installation positions 8 for zippers and pull tabs to be placed and arranged along the circumferential direction. The zipper head conveying device 7 includes an inclined feeding mechanism and a horizontal feeding mechanism. The zipper head has a first state of sliding from the zipper head vibration plate 9 into the inclined feeding mechanism, a second state of being pushed into the horizontal feeding mechanism by the inclined feeding mechanism, and a third state of being aligned in the horizontal feeding mechanism and pushed into the installation position 8. The technical solution is generally By setting a zipper head vibration disk, the zipper heads with uniform orientation are fed into the zipper head conveying device. In the zipper head conveying device, they first pass through the inclined feeding mechanism. Due to the angle difference between the inclined feeding mechanism and the installation position, the zipper head cannot be directly conveyed, so it is transferred through the horizontal feeding mechanism to convert the zipper head into a horizontal state and finally push it into the installation position. This structure can effectively reduce the jamming that occurs during the zipper head unloading process. The installation position rotates with the rotating workbench to the pull-tab conveying device, and the pull tab enters the pull-tab conveying device through the pull-tab vibration disk. The pull tab is unloaded and aligned with the buckle on the zipper head and hung up. Thereafter, it is transported to the riveting device for riveting. After the riveting is completed, it is rotated to the stripping device to complete the stripping. The technical solution has the advantages of high working efficiency and good working stability.

[0070] The inclined feeding mechanism comprises:

[0071] A first fixing bracket 71, which is fixedly mounted on the frame 1, and a mounting seat 711 is provided at an upper end thereof;

[0072] The zipper head conveying track 712 has an upper end connected to the zipper head vibration plate 9 and a lower end fixedly mounted on the first fixed bracket 71. The zipper head conveying track in this embodiment includes a cover 7211 and a bottom strip 7222, with a partition 7233 provided between the two. Figure 3 As shown, the zipper head is provided with an inner cavity for inserting the partition from both sides, so that the zipper head can be stably transported in the zipper head conveying track without rotation, flipping, etc.;

[0073] The zipper head transition assembly 73 is fixedly mounted at the end of the zipper head conveying track 712 and the two are connected for the zipper head to slide, and includes a clamping block 734 for elastically clamping the zipper head; the clamping blocks of the zipper head transition assembly in this embodiment are symmetrically arranged on both sides, and the dimension between the two is smaller than the width dimension of the zipper head, so that the zipper head will be blocked when unloading;

[0074] The zipper head pusher assembly 74 is installed above the zipper head conveying track 712 and has a first action of moving downward to push the zipper head out of the clamping range of the clamping block 734 and a second action of retracting but not affecting the falling of the next zipper head. The function of the zipper head pusher assembly 74 is to push the zipper head into the horizontal feeding mechanism, but only one zipper head is pushed at a time. A limiting mechanism for only one zipper head at a time is provided on the zipper head conveying track, and the limiting mechanism will not be described in detail here.

[0075] The mounting seat 711 is U-shaped and horizontally disposed, and is provided with an inclined surface 713 for the zipper head transition assembly 73 to be installed obliquely.

[0076] The zipper slider transition assembly 73 also includes:

[0077] A transition base 731, which is fixedly mounted on the inclined surface 713 of the mounting base 711;

[0078] Spring seats 732, which are fixedly mounted on both sides of the transition base 731;

[0079] A spring 733 is provided between the spring seat 732 on each side and its corresponding clamp block 734 to interfere with the two. The clamp block 734 is slidably installed in the two side walls of the transition base 731. The clamp block 734 is provided with a chamfer. The spring at the end of the clamp block applies a pre-tightening force to the clamp block so that its head is always in a state of extending into the interior of the transition base, thereby intercepting the zipper head.

[0080] The zipper head pusher assembly 74 includes:

[0081] The tilting driving member 741 is fixedly mounted on the zipper head conveying track 712; the tilting driving member adopts a cylinder;

[0082] A material pushing movable plate 742, which is fixedly connected to the movable end of the inclined driving member 741 and slidably mounted on the upper surface of the zipper head conveying track 712;

[0083] The shift fork 743 is hingedly mounted on the front end of the push material movable plate 742, and a first elastic member 744 is provided between the shift fork 743 and the push material movable plate 742 to connect the two.

[0084] The front end of the pusher movable plate 742 is fixedly installed with a limit plate 745 that cooperates with the pusher movable plate 742 to wrap the upper end of the fork 743 and limit the rotation angle of the fork 743. The fork is in the shape of a fork with two forks, and the two forks are in contact with the clamping blocks on both sides respectively. The two states of the fork are as follows: Fig.11As shown, the shift fork moves forward, and the upper end of the shift fork is limited by the limit plate and does not rotate. The clamping blocks on both sides are pushed open to allow the zipper head to be unloaded. The shift fork retreats and is touched by the zipper head conveying track. It rotates at a certain angle to ensure that the zipper head in the zipper head conveying track can pass smoothly without being blocked by the shift fork. The shift fork and the limit plate are as shown in FIG. Fig.11 As shown, the lower end has a chamfer or arc.

[0085] The horizontal feeding mechanism comprises:

[0086] A rotating seat 721, which is hingedly mounted on both sides of the inner wall of the mounting seat 711;

[0087] The rotating driving member 722 is a cylinder, which is fixedly mounted on the side of the first fixed bracket 71, and its movable end is hinged to the side of the rotating seat 721;

[0088] an alignment assembly comprising clamping plates 723 elastically mounted on both sides;

[0089] The second zipper head pusher assembly includes a horizontal driving member 724 horizontally fixedly mounted on the first fixed bracket 71 and an inserting piece 725 mounted on the movable end of the horizontal driving member 724. The inserting piece 725 passes through the mounting seat 711. The front end of the inserting piece 725 is provided with an inserting strip 7251 that can enter the bottom. The horizontal driving member adopts a cylinder.

[0090] The alignment assembly has a rotating drive member 722 that controls the horizontal state and the inclined state of the rotating seat 721 during rotation. When it is in the inclined state, it is flush with the zipper head transition assembly 73 to ensure smooth entry of the zipper head. When it is in the horizontal state, it is aligned with the installation position 8 and can enable the rear insertion strip 7251 to be inserted and push the zipper head into the installation position 8. After the zipper head is pushed into the alignment assembly by the shift fork, the rotating drive member drives the rotating seat to rotate, changing from the inclined state to the horizontal state. Its height position is flush with the installation position, and the subsequent pushing work can be completed.

[0091] The alignment assembly further comprises:

[0092] Align the bottom plate 726, which is fixedly mounted on the rotating seat 721;

[0093] Cover plate 727, which is fixedly installed on both sides of the alignment base plate 726;

[0094] The alignment base plate 726 is provided with a sliding groove 7261 for the zipper head to slide through, and the clamping plate 723 is slidably mounted on the two side walls of the alignment base plate 726. The clamping plate 723 is composed of a sliding portion 7231 and an extension portion 7232. The extension portion 7232 is plate-shaped and has a chamfered upper end. A second elastic member 728 is provided between the end of the sliding portion 7231 and the inner side wall of the mounting seat 711 to interfere with the two. The zipper head is clamped by the clamping plates on both sides in the sliding groove of the alignment base plate. The clamping plates on both sides are kept in a clamped state by the pre-tightening force of the second elastic member. It is well known that the buckle of the zipper head is movably installed and will swing. In order to ensure that the buckle of the zipper head can be accurately clamped by the mounting position when the zipper head enters the mounting position, the clamping of the zipper head by the clamping plate must be kept centered at all times. Therefore, the clamping plate is provided with an extension portion to keep clamping the zipper head until it is completely separated from the alignment component.

[0095] The pull-tab conveying device 4 comprises:

[0096] A second fixing bracket 41, which is fixedly mounted on the frame 1;

[0097] A pull-tab conveying track 42, the upper end of which is connected to the pull-tab vibration plate 3, and the lower end of which is fixedly mounted on the second fixed bracket 41;

[0098] The second fixed bracket 41 is provided with a pull-tab hanging mechanism 43 corresponding to the bottom end of the pull-tab conveying track 42. The pull-tab conveying track 42 is also provided with a limiting mechanism for controlling the number of pull-tabs falling. The pull-tab hanging mechanism 43 includes a lower baffle assembly 44 and an upper pressing plate assembly 45. The pull-tab has a first state in which it is sent out from the pull-tab conveying track 42 and is caught by the lower baffle assembly 44 and aligned with the zipper head, a second state in which it is pressed on the lower baffle assembly 44 by the upper pressing plate assembly 45, and a lower baffle assembly 44. 44 When the pull tab retracts, the rear end of the pull tab naturally falls and is hung on the zipper head in the third state. When the pull tab is unloaded in the pull tab conveying track, the end with the hole faces downward. The pull tab conveying track is also provided with a limiting mechanism (not shown) for controlling the amount of unloading. It will be described in detail here. The pull tab falls and is caught by the lower baffle assembly and aligned with the buckle on the zipper head. The upper pressure plate assembly starts to move and cooperates with the lower baffle assembly to press the pull tab. After that, the lower baffle assembly retracts, and the pull tab is automatically hung on the buckle of the zipper head under the factor of gravity.

[0099] The lower baffle assembly 44 includes:

[0100] The lower baffle driving member 441 is a cylinder, which is horizontally mounted on the second fixing bracket 41;

[0101] An inclined sliding seat 442, which is fixedly mounted on the movable end of the lower baffle driving member 441, and has a slope 443 on its front surface;

[0102] The lower baffle 444 is fixedly mounted on the slope 443 and has an alignment groove 445 in the middle thereof which is connected to the pull-tab conveying track 42. The lower baffle driving member drives the inclined sliding seat to move to the end of the pull-tab conveying track, and the pull-tab falls into the alignment groove of the lower baffle and automatically aligns with the buckle of the zipper head.

[0103] The upper pressing plate assembly 45 comprises:

[0104] The upper platen driving member 451 is a cylinder, which is horizontally mounted on the side of the second fixing bracket 41;

[0105] The upper pressure plate 452 is fixedly mounted on the movable end of the upper pressure plate driving member 451, and is composed of an integrally formed extension portion 4521 and a pressure strip portion 4522. The extension portion 4521 is horizontally extended, and the pressure strip portion 4522 is inclined and its inclination is consistent with the lower baffle 444 and its position corresponds to the alignment groove 445. The pressure strip portion of the upper pressure plate presses the pull tab in the alignment groove. When the lower baffle retracts, the upper pressure plate is still above the pull tab, which ensures that the pull tab is stably hung and prevents the pull tab from vibrating and thus detaching from the zipper head.

[0106] The installation position 8 comprises:

[0107] A mounting base 81, which is fixedly mounted on the rotating workbench 2, and a mounting groove 82 for mounting a zipper head is provided at the front end thereof;

[0108] A cover body 83, which is arranged above the mounting base 81;

[0111] A lifting drive member 87 is provided on the frame 1 below the movable rod 84 and at a position corresponding to the zipper head conveying device 7 and the stripping device 5. The lifting drive member below adopts a cylinder to push the movable rod upward, and the movable rod drives the cover body to move upward, so that it can be opened to allow the zipper head to enter the installation groove. After installation, the lifting drive member falls back, and the movable rod drives the cover body to return to its original position under the action of the third elastic member, and always provides a pre-tightening force for the cover body and the installation base to fix and clamp the zipper head.

[0112] The riveting device 6 comprises:

[0113] The lifting mechanism is composed of a lifting rod 61, a motor located inside the frame 1, and a cam mechanism. The bottom end of the lifting rod 61 is connected to the upper end of the cam mechanism and extends out of the frame 1. The motor drives the cam mechanism to rotate.

[0114] The translation mechanism is composed of a translation driving member 62 and a riveting rod 63 installed at the movable end of the translation driving member 62. The riveting rod 63 is installed vertically, and the translation driving member 62 is installed horizontally at the top of the lifting rod 61. The riveting rod in the translation mechanism of this embodiment is driven by the translation driving member to move forward to the top of the installation position, and then the lifting mechanism controls the descent of the movable rod. Since the buckle of the zipper head does not require much force to complete the riveting, this embodiment adopts a motor-driven cam mechanism to drive the lifting rod up and down, which can fully meet the requirements; the translation driving member adopts a cylinder

[0115] The stripping device 5 comprises:

[0116] A fixed seat 51 is fixedly mounted on the frame 1 and a horizontally arranged stripping driving member 52 using a cylinder is mounted on its upper end;
