Description

Technical Field

[0001] The present application relates to the technical field of zipper manufacturing, and particularly to an automatic zipper head assembly device. Background Art

[0002] A self-locking zipper head is a zipper head that can achieve self-locking under specific conditions, which can prevent the zipper head from automatically sliding open on the teeth. The self-locking zipper head is usually an alloy part, which includes a head body, a pull tab and a leaf spring. The leaf spring is riveted on the head body and elastically presses the pull tab, and the leaf spring has a card that extends through the opening on the pull tab to the teeth. When the pull tab is in a flat state, the card interferes with the teeth to achieve self-locking and cannot move on the teeth; when the pull tab is in a lifted state, the pull tab pushes the leaf spring to elastically deform upward, and the card is lifted off the teeth to achieve unlocking, so that the zipper head can be pulled on the teeth.

[0003] The assembly of traditional self-locking zipper heads is usually to manually assemble the head body, the pull tab and the leaf spring together and then rivet them. The low degree of automation results in low work efficiency and high labor intensity. Based on this problem, improved solutions have also been proposed in the prior art. For example, the patent document with the Chinese invention patent publication number CN103240361A discloses an assembly machine for the upper spring piece of a self-locking alloy YG head with a pull tab, which can realize the feeding, riveting, detecting and discharging of the zipper head. However, it is applicable to the zipper head in which the pull tab and the head body have been assembled, and the assembly of the pull tab and the head body still needs to be completed manually; moreover, the entire assembly process is completed in the head track, and only after the riveting is completed can the waste products and qualified products be separately discharged, and it is difficult to detect and discharge waste for each step of the assembly process, resulting in a high waste product rate and the components of the waste products being difficult to reuse.

[0004] In view of this, it is necessary to propose a new technical solution to overcome the problems existing in the prior art. Summary of the Invention

[0061] The following will describe in detail some embodiments of the present application with reference to the accompanying drawings. Without conflict, the features in the following embodiments can be combined with each other.

[0062] Please refer to Figures 1 to 17 As shown, the present application provides a zipper head automatic assembly device 100 for assembling a slider 11, a pull tab 12, and a spring piece 13 into a zipper head 200.

[0063] The following will first describe in detail the structure of the zipper head 200 assembled by the zipper head assembly device 100 of the present application. Please refer to Figure 16 and Figure 17 As shown, the zipper head 200 includes a slider 11, a pull tab 12, and a spring piece 13. The slider 11 is for two rows of teeth of the zipper to pass through, and can realize the engagement and separation of the two rows of links when pulled on the two rows of teeth. The top surface of the slider 11 is provided with a front bump 111 and a limit bump 112, and a tab insertion hole 110 is opened near the limit bump 112 on the top surface. A riveting groove 113 is provided on the front side surface of the slider 11. The pull tab 12 is an overall rectangular plate body, one end of which is a connection end for connecting with the slider 11 and the spring piece 13, and the other end is a hand-pulling end for the user to pull when in use. A card hole 122 is opened at the hand-pulling end of the pull tab 12, and an opening 120 is opened at the connection end. Both the opening 120 and the card hole 122 are circumferentially closed and vertically penetrating holes. A rotating shaft bar 121 is formed between the opening 122 and the edge of the connection end. The thickness of the rotating shaft bar 121 is less than its width. In other words, when the pull tab 12 is in a horizontal state, the dimension of the rotating shaft bar 121 in the up and down direction is less than the dimension of the rotating shaft bar 121 in the up and down direction when the pull tab 12 is in a vertical state. The spring piece 13 is an overall L-shaped metal sheet body, which has a riveting portion 131 that can be riveted to the slider 11 and a pressing portion 132 that can elastically press against the rotating shaft bar 121 of the pull tab 12. A limit hole 130 that cooperates with the limit bump 112 of the slider 11 and a tab 133 that cooperates with the tab insertion hole 110 of the slider 11 are also opened on the spring piece 13.

[0064] Please continue to refer to Figure 16 and Figure 17As shown in the figure, the assembly relationship of each component of the slider 200 is as follows: The rotating shaft bar 121 of the pull tab 12 is placed between the front bump 111 and the limiting bump 112 of the slider body 11, and the opening 120 of the pull tab 12 passes through the limiting bump 112 of the slider body 11; The riveting part 131 of the elastic piece 13 is riveted and fixed on the riveting groove 113 of the slider body 11, the pressing part 132 of the elastic piece 13 is pressed on the rotating shaft bar 121 of the pull tab 12, the limiting hole 130 of the elastic piece 13 passes through the limiting bump 112, and the lug 133 of the elastic piece 13 is inserted into the lug jack 110 of the slider body 11. The limiting bump 112 is in an inverted L shape, and it can be clamped with the limiting hole 130 of the elastic piece 13 to limit the upward movement distance of the pressing part 132. The state of the slider 200 during use is as follows: When the pull tab 12 is in a flat state, since the lug 133 passes through the lug jack 110 and is clamped with the teeth of the zipper passing through the slider body 11, the slider 200 cannot move on the teeth, realizing self-locking; When the pull tab 12 is in a lifted state, since the rotating shaft bar 121 changes from a horizontal state to a vertical state, the elastic piece 13 can be pushed to elastically deform upward, and the lug 133 of the elastic piece 13 is lifted away from the teeth, realizing unlocking, so that the slider 200 can be freely pulled on the teeth.

[0065] Please refer to Figures 1 to 15 As shown in the figure, the automatic zipper slider assembling device 100 provided by the present application can be used for automatically assembling the above-mentioned slider 200. The automatic zipper slider assembling device 100 includes a frame 1 and a turntable 2. A plurality of positioning jigs 21 are arranged on the turntable 2, and the slider body 11, the pull tab 12 and the elastic piece 13 are conveyed into the positioning jigs 21 to be assembled into the slider 200. A slider feeding mechanism 3, a pull tab feeding mechanism 4, an elastic piece feeding mechanism 5 and a riveting and fixing mechanism 6 are arranged on the frame 1. The slider feeding mechanism 3 is configured to convey the slider body 11 to the positioning jig 21; The pull tab feeding mechanism 4 is configured to convey the pull tab 12 to the positioning jig 21; The elastic piece feeding mechanism 5 is configured to convey the elastic piece 13 onto the slider body 11 and the pull tab 12 that have been positioned in the positioning jig 21; The riveting and fixing mechanism 6 is configured to: press the elastic piece 13 so that the slider body 11, the pull tab 12 and the elastic piece 13 are in a preset assembly position, and at the preset assembly position, rivet and fix the elastic piece 13 on the slider body 11, and at the same time, the elastic piece 13 is elastically pressed on the pull tab 12.

[0066] Please refer to Figure 3 and Figure 4As shown, it is a jig for assembling a zipper head according to an embodiment of the present application, which includes a turntable 2 and a plurality of positioning jigs 21 provided on the turntable 2. The turntable 2 is an indexing turntable, and a plurality of mold cavities 201 are provided thereon. A positioning jig 21 is correspondingly installed in each mold cavity 201. During operation, the indexing turntable is driven by a motor to rotate one index at a time, so that each positioning jig 21 sequentially passes through each assembly station, so as to complete the corresponding process on each assembly operation.

[0067] Please refer to Figure 4 As shown, the positioning jig 21 is used to limit the slider 11 and the slider plate 12 that can be assembled into the zipper head 200. The positioning jig 21 includes an elastic top member, a bottom plate 212, a slider positioning seat 213, a slider plate positioning seat 214, a pressing block 215 and an elastic pressing rod 216. The bottom plate 212, the slider positioning seat 213, the slider plate positioning seat 214 and the pressing block 215 are provided with screw holes that communicate up and down. A screw passes through the pressing block 215, the slider plate positioning seat 214, the slider positioning seat 213 and the bottom plate 212 from top to bottom in sequence and is locked and connected to the mold cavity 201 of the turntable 2. The slider positioning seat 213 has a slider positioning cavity 2130 for accommodating the slider 11. The slider positioning seat 213 includes a base 2131 and a core-pulling member 2132 installed on the base 2131. The slider positioning cavity 2130 is opened on the base 2131. The end of the core-pulling member 2132 protrudes into the slider positioning cavity 2130. The slider 11 is inserted into the slider positioning cavity 2130 and sleeved on the end of the core-pulling member 2132.

[0068] The elastic top member is arranged below the slider positioning seat 213 and protrudes into the slider positioning cavity 2130, and is used to elastically abut against the slider 11 accommodated in the slider positioning cavity 2130, so as to increase the holding force on the slider 11 and prevent the slider 11 from being thrown out and falling during the rotation of the turntable 2. In this embodiment, the elastic top member includes a spring (not shown) and a top bead 211 elastically abutted by the spring. The bottom wall of the mold cavity 201 of the turntable 2 is provided with a top member mounting hole 2011. The top member mounting hole 2011 is a blind hole. The helical spring is installed in the top member mounting hole 2011. The top bead 211 is installed at the top opening of the blind hole and is elastically supported by the spring. The bottom plate 212 is arranged below the slider positioning seat 213. The bottom plate 212 is provided with a round hole 2120 for the top bead 211 to protrude. The diameter of the round hole 2120 is smaller than the diameter of the top bead 211 to prevent the top bead 211 from falling off upward through the round hole 2120. In this way, when the slider 11 is installed in the slider positioning cavity 2130, the slider 11 is sleeved on the end of the core-pulling member 2132, and the bottom of the slider 11 is located on the bottom plate 212 and is abutted by the top bead 211, realizing the stable positioning of the slider 11 on the positioning jig 21.

[0069] The pull plate positioning seat 214 has a pull plate positioning cavity 2140 for accommodating the pull plate 12. The shape of the pull plate positioning cavity 2140 is the same as the contour shape of the pull plate 12, so as to position the pull plate 12 accommodated therein. The pull plate positioning cavity 2140 is located above the pull head positioning cavity 2130 and communicates with the pull head positioning cavity 2130. The pull plate 12 accommodated in the pull plate positioning cavity 214 overlaps the pull head 11 accommodated in the pull head positioning cavity 213.

[0070] The pressing block 215 is pressed on the pull plate positioning seat 214, and the elastic pressing rod 216 is hinged to the pressing block 215 through the rotating shaft 217. The middle part of the pressing block 215 is provided with an avoidance cavity 2150 connected with the pull plate positioning cavity 2140. The elastic pressing rod 216 is installed in the avoidance cavity 2150 and is rotatably and elastically pressed on the pull plate 12 accommodated in the pull plate positioning cavity 2140. The elastic pressing rod 216 includes a rotating shaft mounting portion 2163 for mounting the rotating shaft 217, and a tilting end 2161 and a crimping end 2162 located on both sides of the rotating shaft mounting portion 2163. The elastic pressing rod 216 is in the form of a seesaw with the rotating shaft 217 as a fulcrum. The tilting end 2161 of the elastic pressing rod 216 is pushed up by an elastic member such as a spring, and the crimping end 2162 is crimped on the pull plate 12. Furthermore, the crimping end 2162 also has a hook 2164 that is clamped in the clamping hole 122 of the pull plate 12, and the clamping hole 122 is a through hole. The cooperation between the hook 2164 and the clamping hole 122 can prevent the pull plate 12 from easily escaping from the pull plate positioning cavity 2140. The outward end surface of the hook 2164 is set as an inclined surface or an arc surface, which has the function of guiding the pull plate 12 to be obliquely inserted under the crimping end 2162. The pull plate positioning seat 214 and the elastic pressure rod 216 limit the pull plate 12 in all directions.

[0071] See also Figure 1 , Figure 2 and Figure 5 As shown, the slider loading mechanism 3 is used to transport the slider 11 to the positioning fixture 21. The slider loading mechanism 3 includes a slider driving cylinder 31 and a slider conveying guide rail 32. The slider conveying guide rail 32 is inclined and is configured to guide the slider 11 to move from top to bottom. The slider driving cylinder 31 is used to punch a slider 11 located at the lower end of the slider conveying guide rail 32 onto the slider positioning seat 213 of the positioning fixture 21. Figure 1 and Figure 2 As shown, the slider loading mechanism 3 also includes a slider regularizing device for regularizing the slider into an orderly state, and the slider regularizing device includes a vibrating plate provided with a regular track.

[0072] See also Figures 6 to 9As shown, the pull plate feeding mechanism 4 is configured to convey the pull plate 12 to the pull plate positioning seat 214. The pull plate feeding mechanism 4 includes a pull plate conveying guide rail 42 and a pull plate pushing device 43 disposed near the lower end of the pull plate conveying guide rail 42. The pull plate conveying guide rail 42 is used to convey the neatly arranged pull plates 12 towards the assembly jig. The pull plate conveying guide rail 42 has a pushing waiting section 424 near the assembly jig, and at least the pushing waiting section 424 is inclined; in this embodiment, the entire pull plate conveying guide rail 42 is inclined from top to bottom. Please refer to Figure 8 As shown, the pull plate conveying guide rail 42 includes a pull plate guide rail main body 421 and a pull plate cover plate 422 covering the pull plate guide rail main body 421. A guide groove for accommodating the pull plate 12 is formed on the pull plate guide rail main body 421, and the pull plate cover plate 422 covers the inner sides of both edges of the guide groove to prevent the pull plate 12 in the guide groove from disengaging upward from the guide groove. As Figure 1 and Figure 2 As shown, the pull plate feeding mechanism 4 further includes a pull plate regularizing device for regularizing the pull plates into an orderly state. The pull plate regularizing device includes a vibrating disk provided with a regularizing track.

[0073] The pull plate pushing device 43 is used to push the pull plate 12 at the lowermost end of the pushing waiting section 424 of the pull plate conveying guide rail 42 to be obliquely inserted between the elastic pressing rod 216 of the positioning fixture 21 and the pull plate positioning seat 214. When the pull plate pushing device 43 retracts, the elastic pressing rod 216 elastically resets to press the pull plate 12 flat in the pull plate positioning seat 214. The pull plate pushing device 43 has a push rod 433 and a driving member for driving the movement of the push rod 433. The driving member is a pull plate driving cylinder 41. The push rod 433 abuts against the pull plate 12 located on the pushing waiting section 424. The driving member drives the push rod 433 to push the pull plate 12 to be obliquely inserted between the pull plate positioning seat 214 of the assembly jig and the elastic pressing rod 216 from the pushing waiting section 424. After the push rod 233 retracts, the pull plate 12 is pressed by the elastic pressing rod 216 and placed horizontally on the pull plate positioning seat 214 from an inclined state.

[0074] Please refer with emphasis to Figure 9As shown, the pull plate pushing device 43 further includes a push rod support. The push rod support includes a first seat body 431 located beside the pull plate conveying guide rail 42, and a second seat body 432 that is rotatably connected to the first seat body 431 and extends above the pull plate conveying guide rail 42. The push rod 433 is arranged on the second seat body 432, and the pull plate driving cylinder 41 is connected to the first seat body 431 through a cylinder push head 411. The push rod support further includes an elastic member 434. In this embodiment, the elastic member 434 is a return spring that provides an elastic force when being stretched and deformed. One end of the elastic member 434 is connected to the first seat body 431, and the other end is connected to the second seat body 432. The elastic member 434 is configured to provide an elastic force for the second seat body 432 to rotate relative to the first seat body 431, so that the push rod 433 located on the second seat body 432 abuts against the pull plate 12. In this embodiment, the push rod 433 abutting against the pull plate 12 specifically means that the lower end of the push rod 433 is inserted into the opening 120 of the pull plate 12 to push the pull plate 12 to be inserted into the assembly jig.

[0075] Please continue to refer to Figure 9As shown, the pull plate pushing device 43 further includes a retraction guide 44, the retraction guide 44 has an upward guide surface 4431, and the upward guide surface 4431 is extended upward in the direction of the push rod 433 retraction; the second seat body 432 is provided with a guide portion 4321 sliding along the upward guide surface 4431, so that the push rod 433 has an upward movement to separate from the pull plate 12 during the retraction process. In this embodiment, the retraction guide 44 includes a fixed seat 444 fixedly arranged beside the pull plate conveying guide rail 42 and a movable seat 442 movably arranged beside the pull plate conveying guide rail 42, the movable seat 442 is provided with a wedge block 443 protruding from the fixed seat 444, and one side of the wedge block 442 forms the upward guide surface 4431. The wedge block 443 is fan-shaped, and has an arc surface, a lower side surface 4432 connected to the lower edge of the arc surface, and an upper side surface 4433 connected to the upper edge of the arc surface, and the arc surface forms the upward guide surface 4431. The lower side surface 4431 is attached to the fixed seat 444, so that the guide portion 4321 of the push rod 433 slides on the upward guide surface 4431 during the retreat process, and the route of the push rod 433 when retreating is an upward arch arc line; a wedge space 4430 is formed between the upper side surface 4432 and the fixed seat 444, so that the guide portion 4321 of the push rod 433 slides from the bottom of the wedge block 443 through the wedge space 4430 during the advancement process, and the route of the push rod 433 when advancing is an inclined straight line. The setting of the wedge block 443 makes the forward and backward paths of the push rod 433 different, ensuring that the push rod 433 can well resist the pull plate 12 when advancing, and can timely detach from the pull plate 12 when retreating to avoid pulling the pull plate 12 out again. Further, the retraction guide 44 includes a mounting seat 441 fixedly arranged beside the pull plate conveying guide rail 42, one end of the movable seat 442 can be rotatably connected to the mounting seat 441, and the other end is provided with the wedge block 443, and the wedge block 443 is overlapped on the fixed seat 444. In this embodiment, the wedge block 443 is overlapped on the fixed seat 444 by relying on the deadweight of the wedge block 443 and the movable seat 442. In other embodiments, an elastic member can be provided to apply force to the movable seat 442 so that the wedge block 443 is overlapped on the fixed seat 444.

[0076] See also Figures 6 to 9As shown in the figure, the operation process of the pull plate loading mechanism 4 is as follows: The pull plate driving cylinder 41 pushes the first seat body 431 forward. The first seat body 431 and the second seat body 432 move forward. The guiding part 4321 on the second seat body 432 passes through between the wedge block 433 and the fixed seat 444. Since the lower end of the push rod 433 on the second seat body 432 is inserted into the opening 120 of the pull plate 12, the pull plate 12 is driven to be obliquely inserted downward between the pull plate positioning seat 214 and the elastic pressing rod 216 of the positioning fixture 21. The pressing end 2162 of the elastic pressing rod 216 is pushed by the pull plate 12 and lifted upward. The pull plate driving cylinder 41 moves backward, and the first seat body 431 and the second seat body 432 are forced to retreat. Since the guiding part 4321 on the second seat body 432 is located outside the lower edge of the arc surface of the wedge block 443, that is, the upward moving guiding surface 4431 at this time, when the second seat body 432 retreats, the guiding part 4321 moves along the arc surface of the wedge block 443, causing the second seat body 432 to rotate upward relative to the mounting seat 441, driving the push rod 433 to lift up and detach from the opening 120 of the pull plate 12, so that the push rod 433 will not bring out the pull plate 12 pushed into the positioning fixture 21 when it retreats. After the push rod 433 retreats, the pressing end 2162 of the elastic pressing rod 216 of the positioning fixture 21 moves downward to press the pull plate 12.

[0077] Please refer to Figures 10 to 12 As shown in the figure, the shrapnel loading mechanism 5 is used to convey the shrapnel 13 to the assembly fixture of the zipper head. The shrapnel 13, the pull head 11, and the pull plate 12 are assembled into the zipper head 200 on the assembly fixture. The shrapnel loading mechanism includes 51, a shrapnel conveying guide rail 52, a receiving member 53, a receiving member mounting seat 54, and a return spring 55. The shrapnel conveying guide rail 52 is used to convey the neatly arranged shrapnel 13 towards the assembly fixture. The shrapnel conveying guide rail 52 has an end close to the assembly fixture. The receiving member 53 is docked at the end of the shrapnel conveying guide rail 52 to receive the shrapnel 13 conveyed from the end of the shrapnel conveying guide rail 52. The receiving member 53 is located above the assembly fixture and can rotate in the vertical plane. The driving assembly 51 includes a driving cylinder and a driving ejector rod 511. The driving cylinder drives the driving ejector rod 511 to push the receiving member 53 to rotate from top to bottom, so that the shrapnel 13 located on the receiving member 53 moves down to the assembly fixture. As Figure 1 and Figure 2 shown in the figure, the shrapnel loading mechanism 5 further includes a shrapnel regularizing device for regularizing the shrapnel into an orderly state. The shrapnel regularizing device includes a vibrating disk provided with a regularizing track.

[0078] Specifically, the shrapnel conveying guide rail 52 includes an upper section guide rail 521 and a lower section guide rail 522 that are separately arranged. The upper section guide rail 521 is inclined and straight, and the lower section guide rail 522 is arc-shaped and is smoothly connected to the upper section guide rail 521. The upper section guide rail 521 includes a guide rail main body 5211 and a cover plate 5212 covering the guide rail main body 5211. An upper section guide groove for accommodating the shrapnel 13 is formed on the guide rail main body 5211, and the cover plate 5212 covers above the upper section guide groove to prevent the shrapnel 13 in the upper section guide groove from disengaging upward from the upper section guide groove. The lower section guide rail 522 includes an outer mold 5222 and a mold core 5221 disposed inside the outer mold 5222. A lower section guide groove is formed between the mold core 5221 and the outer mold 5222. The shrapnel 13 conveyed by the shrapnel conveying guide rail 52 changes from an inclined state to a horizontal state and is conveyed to the receiving member 53 one by one.

[0079] Please refer to Figure 11 and Figure 12 As shown, the receiving member 53 includes a rotating shaft portion 531, a receiving portion 532 and a reset force applying portion 533 that perform a seesaw motion with the rotating shaft portion 531 as a fulcrum. The rotating shaft portion 531 is used to rotatably connect the receiving member 53 through a rotating shaft. The receiving portion 532 is docked with the end of the shrapnel conveying guide rail 52. The reset force applying portion 533 is used to be stressed to drive the receiving member 53 to reset when the driving ejector rod 511 retracts. In this embodiment, a reset spring 55 in a tensioned state is connected to the reset force applying portion 533. The reset force applying portion 533 includes a connecting shaft 5331, and one end of the reset spring 55 is sleeved on the connecting shaft 5331. The receiving member 53 is rotatably connected to the receiving member mounting seat 54 through a rotating shaft. The receiving member mounting seat 54 has a mounting groove, and the receiving member 53 is pivotally connected in the mounting groove in a plate shape. The reset force applying portion 533 further includes a limiting block 534 that abuts against the receiving member mounting seat 54 to limit the receiving member 53 in the reset position. The shrapnel conveying mechanism 5 conveys the shrapnel 13 to the positioning fixture 21 and places it on the pull head 11 and the pull plate 12 that have been positioned on the positioning fixture 21, and will be riveted and fixed at the next working station.

[0080] Please refer to Figures 13 to 15As shown, the riveting and fixing mechanism 6 includes a positioning component and a riveting component. The positioning component includes an upper ejector pin 62 vertically pressing against the top of the elastic piece 13 and an upper ejector pin driving cylinder 61 for driving the movement of the upper ejector pin 62. The crimping portion 132 and the riveting portion 131 of the elastic piece 13 are connected in an L shape. The crimping portion 132 is located on the top surface of the pull head 11, and the riveting portion 131 is located on the side surface of the pull head 11. The positioning component further includes a side ejector pin 63 horizontally pressing against the riveting portion 131. The side ejector pin 63 is driven by an ejector pin cam 631. The riveting component includes a riveting head 64, and the riveting head 64 is driven by a riveting cam 641. The movement of the riveting cam 641 driving the riveting head 64 lags behind the movement of the ejector pin cam 631 driving the side ejector pin 63. In this way, the side ejector pin 63 can move first to tightly press the riveting portion 131 in place, and then the riveting action can be carried out, which can improve the riveting quality. In this embodiment, the ejector pin cam 631 and the riveting cam 641 are connected to the same driving shaft 65 for coaxial driving. The ejector pin cam 631 is located above the riveting cam 641. The ejector pin cam 631 drives the movement of the side ejector pin 63 through a first convex circle 632, and the riveting cam 641 drives the movement of the riveting head 54 through a second convex circle 642. In the rotation direction of the ejector pin cam 631 and the riveting cam 641, the convex portion of the ejector pin cam 631 is located in front of the convex portion of the riveting cam 641 to realize the sequential execution of side pressing and riveting.

[0081] In this embodiment, the riveting and fixing process is as follows: First, the upper ejector pin driving cylinder 61 pushes the upper ejector pin 62 to press the elastic piece 13 downward from the top; then, the ejector pin cam 631 drives the side ejector pin 63 to tightly press the elastic piece 13 laterally so that the riveting portion 131 of the elastic piece 13 is closely attached to the riveting groove 113 of the pull head; finally, the riveting cam 641 drives the riveting head 64 to rivet and fix the riveting portion 131 on both sides of the riveting groove 113.

By adding the second riveting mechanism 7, the riveting quality can be ensured; since the zipper head 200 at the station of the second riveting mechanism 7 has already been riveted once, the second riveting mechanism 7 does not need to cause a large riveting amount to the pull head 11, and the second riveting mechanism 7 is not easily worn and has a better service life. The component structures of the second riveting mechanism 7 are the same as those of the riveting and fixing mechanism 6, and the two can share the upper thimble driving cylinder 61. The component structures of the second riveting mechanism 7 can be understood by referring to the riveting and fixing mechanism 6 and will not be elaborated here.

The detection device further includes an elastic piece detection device 83 arranged between the elastic piece feeding mechanism 5 and the riveting and fixing mechanism 6 for detecting whether the elastic piece 13 is fed in place, and a riveting detection device 84 arranged between the riveting and fixing mechanism 6 and the finished product taking-out mechanism 93 for detecting whether the riveting is qualified. The elastic piece detection device 83 and the riveting detection device 84 are optical detection devices, that is, they detect by taking pictures or other optical imaging methods. A first waste discharging mechanism 91 is arranged between the elastic piece detection device 83 and the riveting and fixing mechanism 84, and the first waste discharging mechanism 91 is used to take out the unqualified zipper heads 200 detected by the elastic piece detection device 83 from the positioning jig 21. A second waste discharging mechanism 92 is arranged between the riveting detection device 84 and the finished product taking-out mechanism 93, and the second waste discharging mechanism 92 is used to take out the unqualified zipper heads 200 detected by the riveting detection device 84 from the positioning jig 21. The technical solution of the present application enables the assembly stations to be arranged in sequence through the use of the indexing turntable, and can perform detection after each action station, realizing timely detection and waste discharging of each step in the assembly process, which can reduce the scrap rate and timely recycle and reuse the unassembled components before riveting.
