Description

Technical Field

[0001] The present invention belongs to the field of zippers, and particularly relates to an automatic assembly machine for a pull head with a thin elastic piece. Background Art

[0002] As one of the common tools on clothes, a zipper usually includes a chain belt and a pull head. The pull head slides back and forth on the chain belt, enabling the chain belt to quickly close the clothing. Among them, the pull head with a self-locking function is widely popular because it can prevent the pull head from accidentally sliding. To meet the market demand, automated equipment for assembling pull heads has emerged on the market to improve the assembly efficiency of pull heads. However, most of the existing automated equipment for assembling pull heads cannot assemble thin elastic pieces, and the assembly of thin elastic pieces still uses traditional manual assembly.

[0003] In the prior art, as disclosed in the patent document with the publication number CN218852099U, an automated assembly machine for a self-locking pull head for a zipper is disclosed, which includes an elastic piece feeding mechanism. The elastic piece feeding mechanism includes a driving component and a receiving part. The driving component rotates the receiving part through driving, so that the elastic piece on the receiving part is installed on the fixture. However, the thin elastic piece is light, thin, and small, and is prone to displacement during the flipping process, and this structure is not suitable for thin elastic pieces. Summary of the Invention

[0004] Aiming at the problems in the prior art, the present invention provides an automatic assembly machine for a pull head with a thin elastic piece. The thin elastic piece is automatically fed by the vacuum component of the elastic piece feeding mechanism, and the fed thin elastic piece is fixed to the pull head by a riveting mechanism, realizing the automatic assembly of the pull head with a thin elastic piece.

[0005] The present invention is realized as follows: An automatic assembly machine for a pull head with a thin elastic piece includes a frame. A transfer mechanism is provided on the frame. A pull head feeding mechanism, an elastic piece feeding mechanism, a riveting mechanism, and a discharging mechanism are sequentially arranged along the transfer direction of the transfer mechanism on the periphery of the transfer mechanism.

[0006] The pull head feeding mechanism includes a first conveying mechanism. A first guide rail is provided at the end of the first conveying mechanism. The pull head enters the first guide rail under the conveying of the first conveying mechanism. A pushing mechanism is provided at the end of the first guide rail. The pull head located at the end of the first guide rail enters the transfer mechanism under the pushing of the pushing mechanism. The first guide rail is used to guide the moving pull head to prevent the pull head from changing its posture during movement. The pushing mechanism makes the pull head more firmly installed on the transfer mechanism by pushing, thereby preventing the pull head from falling out of the transfer mechanism during transfer and improving the reliability of the pull head during transfer.

[0007] The chip loading mechanism includes a second conveying mechanism. A second guide rail is provided at the end of the second conveying mechanism. The thin chips enter the second guide rail under the conveyance of the second conveying mechanism. A grasping mechanism is provided at the end of the second guide rail. The grasping mechanism includes a first driving device, a sliding seat, and a vacuum assembly. The sliding seat is in transmission connection with the first driving device. The vacuum assembly is slidably mounted on the sliding seat. The first driving device drives the sliding seat and the vacuum assembly in sequence, so that the vacuum assembly moves back and forth between the second guide rail and the transfer mechanism. Due to the characteristics of small size, light weight, and thinness of the thin chips, grasping the thin chips by clamping is likely to cause deformation of the thin chips, and installing the thin chips by translation or inversion is likely to cause displacement of the thin chips, resulting in misalignment of the thin chips. Moreover, the thin chips also have the characteristic of a flat surface. The vacuum assembly can grasp the thin chips without damaging them. At the same time, the vacuum suction method can also prevent the thin chips from being displaced during the loading process, improving the reliability and loading accuracy of the grasping mechanism.

[0008] The riveting and pressing mechanism includes a riveting and pressing unit and a detection unit arranged in sequence along the transfer direction of the transfer mechanism, with the detection unit being arranged at the rear end of the riveting and pressing unit. Since the risk of displacement of the chips after loading only exists in the process from chip loading to chip riveting and pressing, compared with placing the detection unit at the front end of the riveting and pressing unit, when the detection unit is placed at the rear end of the riveting and pressing unit, at this time, the chips only pass through the transfer of one station from loading to riveting and pressing. While when the detection unit is placed at the front end of the riveting and pressing unit, the chips pass through the transfer of two stations from loading to detection and then to riveting and pressing. Comparing the two, placing the detection unit at the rear end of the riveting and pressing unit also reduces the risk of chip displacement.

[0009] The riveting and pressing unit and the detection unit are in transmission connection with the transfer mechanism and move synchronously under the drive of the transfer mechanism. By driving the riveting and pressing unit and the detection unit simultaneously through the transfer mechanism, it is possible to save additional power sources and reduce the manufacturing cost of the riveting and pressing mechanism.

[0010] The unloading mechanism includes a second driving unit. A claw adapted to the pull head is provided at the output end of the second driving unit, which is used to disengage the pull head from the transfer mechanism. Since the pull head is installed on the transfer mechanism through a pushing mechanism, there is a pre-tightening force between the pull head and the transfer mechanism. When the pull head needs to be disengaged from the transfer mechanism, the claw can overcome the pre-tightening force between the pull head and the transfer mechanism to disengage the pull head from the transfer mechanism, improving the reliability of the unloading mechanism.

[0011] Preferably, the grasping mechanism includes a base, on which a pressing plate is provided, and the first driving device drives the pressing plate to move up and down longitudinally; a sliding seat is also horizontally slidably connected to the base, and a vacuum assembly is longitudinally slidably connected to the sliding seat; an adsorption port is provided at the lower end of the vacuum assembly for sucking the elastic sheet; the vacuum assembly is located below the pressing plate, and the pressing plate abuts or separates from the vacuum assembly; a transmission member is further provided at the lower end of the pressing plate, and the transmission member is used to convert the longitudinal lifting of the pressing plate into the horizontal movement of the sliding seat; the second guide rail is in communication with the second conveying mechanism for receiving the elastic sheet conveyed by the second conveying mechanism for the vacuum assembly to suck; due to the characteristics of small size, light weight and thinness of the thin elastic sheet, grasping the thin elastic sheet by clamping is likely to cause deformation of the thin elastic sheet, and the thin elastic sheet also has the characteristic of a flat surface, and the vacuum assembly can grasp the thin elastic sheet without damaging it, improving the reliability of the grasping mechanism.

[0012] When the elastic sheet is sucked by the vacuum assembly; the pressing plate presses down, first driving the sliding seat to move horizontally, and then pressing against the vacuum assembly to move down, so as to convey the elastic sheet to the zipper head. By driving the vacuum assembly and the sliding seat respectively by the pressing plate and the transmission member, the vacuum assembly moves in different directions in sequence under the drive of a single power source, saving the number of power sources and reducing the cost of the grasping mechanism.

[0013] Specifically, a first inclined surface corresponding to the sliding seat is provided at the lower part of the transmission member, a second inclined surface adapted to the first inclined surface is provided on the sliding seat, and the first inclined surface and the second inclined surface are connected by a wedge to drive the sliding seat to slide outwards; a spacing is provided between the pressing plate and the vacuum assembly. After the transmission member drives the sliding seat in place, the pressing plate presses against the vacuum assembly and drives the vacuum assembly to slide longitudinally. Through the wedge connection between the first inclined surface and the second inclined surface, the vertical movement of the transmission member can be directly converted into horizontal movement, reducing the parts required for movement conversion, thereby reducing the complexity of the grasping mechanism and improving the stability.

[0014] Specifically, the gripping mechanism further includes a first reset mechanism and a second reset mechanism. The first reset mechanism includes a first elastic unit, one end of which is connected to the transmission member, and the other end is elastically connected to the vacuum component. Since the transmission member is pressed against the vacuum component, when the transmission member is reset, the vacuum component cannot be reset. The first elastic unit elastically connects the transmission member to the vacuum component, so that the vacuum component can be reset at any time when the transmission member is reset, thereby improving the reliability of the vacuum component. The second reset mechanism includes an elastic pressure rod, which is elastically pressed against the sliding seat. Since the sliding seat is connected to the transmission member in an oblique wedge manner, the transmission member cannot drive the sliding seat to reset after being reset. The elastic pressure rod causes the sliding seat to be subjected to a reset thrust. When the transmission member is reset, the sliding seat is automatically reset under the thrust of the elastic pressure rod, thereby improving the reliability of the sliding seat.

[0015] Specifically, the transfer mechanism includes a third drive device, a transmission shaft and a turntable which are sequentially connected in transmission. The third drive device drives the transmission shaft to rotate, thereby driving the turntable to rotate. The transmission shaft is also provided with a first transmission mechanism, which includes an eccentric wheel, a swing arm sleeved with the eccentric wheel, and a slide bar hinged with the swing arm. The riveting unit and the detection unit are installed on the slide bar, and the slide bar drives the riveting unit and the detection unit to move synchronously. The slide bar simultaneously connects the riveting unit and the detection unit, so that the riveting unit and the detection unit move synchronously in a linkage manner, which reduces the power source and reduces the cost.

[0016] Specifically, the transfer mechanism also includes a divider, the input end of the divider is connected to the transmission shaft, and the output end is connected to the turntable, so as to convert the continuous rotation of the transmission shaft into intermittent rotation of the turntable, so that when the riveting unit is riveting, the turntable is in a stationary state, thereby improving the riveting effect of the riveting mechanism and thus improving the reliability of the riveting mechanism.

[0017] Specifically, the turntable is also provided with a plurality of slider clamps, the slider clamps include a mounting seat relatively fixed to the turntable, and the mounting seat is also provided with a discharge port; since the slider is installed on the slider clamp by plugging, the slider will wear and produce waste during the plugging process, and the waste can be discharged in time through the discharge port to prevent the slider clamp from further wear, thereby increasing the service life of the slider clamp. A detachable positioning unit is provided on the mounting seat, and positioning parts are symmetrically provided at both ends of the positioning unit, so that the positioning unit can be used in both directions. When one end is excessively worn, the other end can be replaced for use, further increasing the service life of the slider clamp.

[0018] Specifically, the positioning portion includes a first support portion and second support portions symmetrically arranged on both sides of the first support portion. When the slider is connected to the positioning unit, the first support portion extends into the interior of the slider and abuts against the top plate and the bottom plate of the slider simultaneously; a gap for the chain belt to pass through is provided on the side plate of the slider, and the gap divides the side plate into an upper side plate and a lower side plate. The second support portions pass through the gap and abut against the upper side plate and the lower side plate simultaneously. By means of the first support portion and the second support portions supporting the top plate, the bottom plate and the side plate of the slider during riveting, it is prevented that the interior of the slider is suspended during riveting, thereby reducing the risk of deformation of the slider during riveting and improving the reliability of the positioning unit.

[0019] Preferably, the pushing mechanism includes a turning platform hinged to the end of the first guide rail, a third driving unit for driving the turning platform to rotate, and a pushing unit for pushing the slider. After the slider at the end of the first guide rail enters the turning platform, the third driving unit drives the turning platform to rotate so that the turning platform is docked with the transfer mechanism. Subsequently, the pushing unit pushes the slider on the turning platform to make the slider enter the transfer mechanism. By means of the turning platform turning the slider, the pushing unit can complete the pushing of the slider without affecting the continuous feeding of the slider, thereby improving the convenience of feeding the slider.

[0020] Preferably, there are two discharging mechanisms, which are arranged in sequence and are respectively formed into a finished product discharging mechanism and a defective product discharging mechanism. The finished product discharging mechanism is used for discharging finished products, and the defective product discharging mechanism is used for discharging defective products, enabling the automatic assembly machine to distinguish between finished products and defective products and improving the practicability of the automatic assembly machine.

[0021] Specifically, a finished product channel corresponding to the finished product discharging mechanism is further provided on the frame. The finished product channel is inclined, and its end extends out of the side wall of the frame. By means of the finished product channel extending out of the side wall of the frame, the finished products can be directly collected outside the assembly machine, thereby improving the efficiency of collecting finished products.

[0022] Preferably, an operation panel is further provided on the frame. The operation panel is electrically connected to the slider feeding mechanism, the shrapnel feeding mechanism, the riveting mechanism and the discharging mechanism. The operation panel can not only control the slider feeding mechanism, the shrapnel feeding mechanism, the riveting mechanism and the discharging mechanism uniformly, significantly improving the production efficiency and operation coherence, but also can display the equipment status in real time, such as fault alarm and operation parameters, facilitating quick maintenance in case of equipment failure and improving the maintenance convenience of the automatic assembly machine.

[0023] The beneficial effects of the present invention:

[0024] The present invention provides an automatic assembly machine with a thin elastic tab pull head. The pull head is pushed to a transfer mechanism by a pushing mechanism of a pull head feeding machine head, realizing automatic feeding of the pull head; a vacuum component of a tab feeding mechanism sucks the thin elastic tab, realizing automatic feeding of the thin elastic tab while preventing damage to the thin elastic tab and misalignment during feeding; the fed thin elastic tab is fixed to the pull head by a riveting and pressing mechanism; and the finished product is automatically discharged by a discharging mechanism, thereby realizing automatic assembly of the pull head with a thin elastic tab and improving the production efficiency of the pull head with a thin elastic tab.

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0040] As Figures 1 - 12 shown, an automatic assembly machine for a pull head with a thin shrapnel includes a frame 1, and a transfer mechanism 2 is provided on the frame 1. A pull head feeding mechanism 3, a shrapnel feeding mechanism 4, a riveting mechanism 5, and a discharging mechanism 6 are sequentially arranged along the transfer direction of the transfer mechanism 2 on the periphery of the transfer mechanism 2.

[0041] The pull head feeding mechanism 3 includes a first conveying mechanism 31. A first guide rail 32 is provided at the end of the first conveying mechanism 31. The pull head enters the first guide rail 32 under the conveyance of the first conveying mechanism 31. A pushing mechanism 33 is provided at the end of the first guide rail 32. The pull head located at the end of the first guide rail 32 enters the transfer mechanism 2 under the push of the pushing mechanism 33. The first guide rail 32 is used to guide the moving pull head to prevent the pull head from changing its posture during movement. The pushing mechanism 33 makes the pull head more firmly installed on the transfer mechanism 2 by pushing, thereby preventing the pull head from falling out of the transfer mechanism 2 during transfer and improving the reliability of the pull head during transfer.

[0042] In this embodiment, the pushing mechanism 33 includes a turning platform 331 hinged to the end of the first guide rail 32, a third driving unit 332 for driving the turning platform 331 to rotate, and a pushing unit 333 for pushing the pull head. After the pull head at the end of the first guide rail 32 enters the turning platform 331, the third driving unit 332 drives the turning platform 331 to rotate so that the turning platform 331 is docked with the transfer mechanism 2. Subsequently, the pushing unit 333 pushes the pull head on the turning platform 331 to make the pull head enter the transfer mechanism 2. By means of turning the pull head by the turning platform 331, the pushing unit 333 can complete the pushing of the pull head without affecting the continuous feeding of the pull head, improving the convenience of feeding the pull head.

[0043] The thin elastic sheet feeding mechanism 4 includes a second conveying mechanism 41. A second guide rail 42 is provided at the end of the second conveying mechanism 41. The thin elastic sheet enters the second guide rail 42 under the conveyance of the second conveying mechanism 41. A grasping mechanism 43 is provided at the end of the second guide rail 42. The grasping mechanism 43 includes a first driving device 431, a sliding seat 433, and a vacuum assembly 434. The sliding seat 433 is in transmission connection with the first driving device 431. The vacuum assembly 434 is mounted on the sliding seat 433 in a slidable manner. The first driving device 431 drives the sliding seat 433 and the vacuum assembly 434 in sequence, so that the vacuum assembly 434 moves back and forth between the second guide rail 42 and the transfer mechanism 2. Since the thin elastic sheet is small, light, and thin, grasping the thin elastic sheet by clamping is likely to cause deformation of the thin elastic sheet, and installing the thin elastic sheet by translation or inversion is likely to cause displacement of the thin elastic sheet, resulting in misalignment of the thin elastic sheet. The thin elastic sheet also has a flat surface. The vacuum assembly 434 can grasp the thin elastic sheet without damaging it. At the same time, the vacuum suction method can also prevent the thin elastic sheet from being displaced during the feeding process, improving the reliability and feeding accuracy of the grasping mechanism 43.

[0044] The riveting mechanism 5 includes a riveting unit 54 and a detection unit 55 arranged in sequence along the transfer direction of the transfer mechanism 2, so that the detection unit 55 is arranged at the rear end of the riveting unit 54. Since the risk of displacement of the elastic sheet after feeding only exists in the process from elastic sheet feeding to elastic sheet riveting, compared with placing the detection unit 55 at the front end of the riveting unit 54, when the detection unit 55 is placed at the rear end of the riveting unit 54, at this time, the elastic sheet only passes through the transfer of one station from feeding to riveting; while when the detection unit 55 is placed at the front end of the riveting unit 54, the elastic sheet passes through the transfer of two stations from feeding to detection and then to riveting. Comparing the two, placing the detection unit 55 at the rear end of the riveting unit 54 also reduces the risk of displacement of the elastic sheet.

[0045] The riveting unit 54 and the detecting unit 55 are in transmission connection with the transfer mechanism 2 and move synchronously under the drive of the transfer mechanism 2. By driving the riveting unit 54 and the detecting unit 55 simultaneously through the transfer mechanism 2, an additional power source can be saved, and the manufacturing cost of the riveting mechanism 5 is reduced.

[0046] In this embodiment, the grasping mechanism 43 includes a base 437. A pressing plate 438 is provided on the base 437. The first driving device 431 drives the pressing plate 438 to move up and down longitudinally. A sliding seat 433 is also connected to the base 437 in a transverse sliding manner. A vacuum assembly 434 is connected to the sliding seat 433 in a longitudinal sliding manner. An adsorption port is provided at the lower end of the vacuum assembly 434 for sucking the shrapnel. The vacuum assembly 434 is located below the pressing plate 438, and the pressing plate 438 abuts against or separates from the vacuum assembly 434. A transmission member 432 is further provided at the lower end of the pressing plate 438. The transmission member 432 is used to convert the longitudinal up and down movement of the pressing plate 438 into the transverse movement of the sliding seat 433. The second guide rail 42 is in communication with the second conveying mechanism 41 for receiving the shrapnel from the second conveying mechanism 41 for the vacuum assembly 434 to suck. Since the thin shrapnel has the characteristics of being small, light and thin, grasping the thin shrapnel by clamping is likely to cause the thin shrapnel to deform. And the thin shrapnel also has the characteristic of a flat surface. The vacuum assembly 434 can grasp the thin shrapnel without damaging it, improving the reliability of the grasping mechanism.

[0047] When the shrapnel is sucked by the vacuum assembly 434, the pressing plate 438 presses down, first driving the sliding seat 433 to move transversely, and then pressing against the vacuum assembly 434 to move down, so as to convey the shrapnel to the zipper head. By driving the vacuum assembly 434 and the sliding seat 433 respectively through the pressing plate 438 and the transmission member 432, the vacuum assembly 434 moves in different directions in sequence under the drive of a single power source, saving the number of power sources and reducing the cost of the grasping mechanism 43.

[0048] Specifically, a first inclined surface 4321 corresponding to the sliding seat 433 is provided at the lower part of the transmission member 432, a second inclined surface 4331 adapted to the first inclined surface 4321 is provided on the sliding seat 433, and the first inclined surface 4321 and the second inclined surface 4331 are connected by a wedge to drive the sliding seat 433 to slide outwards; there is a spacing between the pressing plate 438 and the vacuum assembly 434. After the transmission member 432 drives the sliding seat 433 in place, the pressing plate 438 presses against the vacuum assembly 434 and drives the vacuum assembly 434 to slide longitudinally. Through the wedge connection between the first inclined surface 4321 and the second inclined surface 4331, the vertical movement of the transmission member 432 can be directly converted into horizontal movement, reducing the parts required for movement conversion, thereby reducing the complexity of the grasping mechanism and improving the stability. The first driving device 431.

[0049] Specifically, the grasping mechanism 43 further includes a first reset mechanism and a second reset mechanism. The first reset mechanism includes a first elastic unit 435. One end of the first elastic unit 435 is connected to the transmission member 432, and the other end is elastically connected to the vacuum assembly 434; since the transmission member 432 presses against the vacuum assembly 434, when the transmission member 432 is reset, it cannot drive the vacuum assembly 434 to reset. The first elastic unit 435 elastically connects the transmission member 432 and the vacuum assembly 434, so that the vacuum assembly 434 is reset along with the reset of the transmission member 432, improving the reliability of the vacuum assembly 434. The second reset mechanism includes an elastic pressure rod 436, and the elastic pressure rod 436 elastically presses against the sliding seat 433. Since the sliding seat 433 is connected to the transmission member 432 by a wedge, the transmission member 432 cannot drive the sliding seat 433 to reset after resetting. The elastic pressure rod 436 applies a resetting thrust to the sliding seat 433. After the transmission member 432 is reset, the sliding seat 433 is automatically reset under the thrust of the elastic pressure rod 436, improving the reliability of the sliding seat 433.

[0050] Specifically, the transfer mechanism 2 includes a third driving device, a transmission shaft and a turntable 21 which are sequentially connected in transmission. The third driving device drives the transmission shaft to rotate, thereby driving the turntable 21 to rotate. The transmission shaft is also provided with a first transmission mechanism, which includes an eccentric wheel 51, a swing arm 52 sleeved with the eccentric wheel 51, and a slide bar 53 hinged with the swing arm 52. The riveting unit 54 and the detection unit 55 are installed on the slide bar 53, and the slide bar 53 drives the riveting unit 54 and the detection unit 55 to move synchronously. The slide bar 53 simultaneously connects the riveting unit 54 and the detection unit 55, so that the riveting unit 54 and the detection unit 55 move synchronously in a linkage manner, which reduces the power source and reduces the cost.

[0051] Specifically, the transfer mechanism 2 also includes a divider 22, the input end of the divider 22 is connected to the transmission shaft, and the output end is connected to the turntable 21, so as to convert the continuous rotation of the transmission shaft into the intermittent rotation of the turntable 21, so that when the riveting unit 54 is riveting, the turntable 21 is in a stationary state, thereby improving the riveting effect of the riveting mechanism 5 and thus improving the reliability of the riveting mechanism 5.

[0052] Specifically, the rotating disk 21 is also provided with a plurality of slider clamps 23, and the slider clamps 23 include a mounting seat 231 relatively fixed to the rotating disk 21, and a discharge port 2311 is also provided on the mounting seat 231; since the slider is installed on the slider clamp 23 by plugging, the slider will wear and produce waste during the plugging process, and the waste can be discharged in time through the discharge port 2311 to prevent the slider clamp 23 from further wearing, thereby improving the service life of the slider clamp 23. A detachable positioning unit 232 is provided on the mounting seat 231, and positioning parts 2321 are symmetrically provided at both ends of the positioning unit 232, so that the positioning unit 232 can be used in both directions. When one end is excessively worn, the other end can be replaced for use, further improving the service life of the slider clamp 23.

[0053] Specifically, the positioning portion 2321 includes a first support portion 43211 and second support portions 43212 symmetrically disposed on both sides of the first support portion 43211. When the slider is connected to the positioning unit 232, the first support portion 43211 extends into the interior of the slider and abuts against the top plate and the bottom plate of the slider at the same time; a gap for the chain belt to pass through is provided on the side plate of the slider, and the gap divides the side plate into an upper side plate and a lower side plate. The second support portion 43212 passes through the gap and abuts against the upper side plate and the lower side plate at the same time. By means of the first support portion 43211 and the second support portions 43212 supporting the top plate, the bottom plate and the side plate of the slider during riveting, it is prevented that the interior of the slider is suspended during riveting, thereby reducing the risk of deformation of the slider during riveting and improving the reliability of the positioning unit.

[0054] The blanking mechanism 6 includes a second driving unit 61, and a claw 62 adapted to the slider is provided at the output end of the second driving unit 61 for separating the slider from the transfer mechanism 2. Since the slider is mounted on the transfer mechanism 2 through the pushing mechanism 33, a pre-tightening force is generated between the slider and the transfer mechanism 2. When the slider needs to be separated from the transfer mechanism 2, the claw 62 can overcome the pre-tightening force between the slider and the transfer mechanism 2 to separate the slider from the transfer mechanism 2, improving the reliability of the blanking mechanism 6.

[0055] In this embodiment, two blanking mechanisms 6 are provided and arranged in sequence, which are respectively formed into a finished product blanking mechanism and a defective product blanking mechanism. The finished product blanking mechanism is used for blanking finished products, and the defective product blanking mechanism is used for blanking defective products, enabling the automatic assembly machine to distinguish between finished products and defective products and improving the practicability of the automatic assembly machine.

[0056] Specifically, a finished product channel corresponding to the finished product blanking mechanism is further provided on the frame 1. The finished product channel is inclined, and its end extends out of the side wall of the frame 1. By means of the finished product channel extending out of the side wall of the frame 1, the finished products can be directly collected outside the assembly machine, improving the finished product collection efficiency.

[0057] In this embodiment, an operation panel 7 is further provided on the frame 1. The operation panel 7 is electrically connected to the slider loading mechanism 3, the shrapnel loading mechanism 4, the riveting mechanism 5 and the blanking mechanism 6.
