[0006] when the elastic sheet is sucked by vacuum suction rod, the pressing plate is pressed down, first drive sliding seat horizontal movement, then press vacuum suction rod down, and the elastic sheet is conveyed to zip head.

[0007] Preferably, the hand component further comprises a first reset device and a second reset device corresponding to the sliding seat and the vacuum suction rod respectively, and the first reset device and the second reset device are in transmission connection with the sliding seat and the vacuum suction rod respectively. The first reset device and the second reset device are used for driving the sliding seat and the vacuum suction rod to reset respectively, so as to ensure the repeated accuracy of the vacuum suction rod when catching the thin elastic sheet each time, and improve the reliability of the hand component.

[0008] Preferably, the first reset device comprises a mounting seat, a first elastic unit and a pressing rod in sliding connection with the mounting seat, one end of the first elastic unit is in abutment with the mounting seat, and the other end is in elastic connection with the pressing rod, and the pressing rod is driven to press the sliding seat. Since the sliding seat is in wedge connection with the transmission member, when the transmission member resets, the sliding seat will not reset automatically, the first elastic unit drives the pressing rod to press the sliding seat, so that the sliding seat is always in contact with the transmission member, and when the transmission member resets, the sliding seat resets synchronously, thereby improving the repeated accuracy of the vacuum suction rod when catching the thin elastic sheet each time, and improving the reliability of the hand component.

[0009] Specifically, the mounting seat is L-shaped, the end of the pressing rod passes through the mounting seat to form a clamping part. The second conveying channel is provided with a hollow part corresponding to the pressing rod, and the pressing rod covers the hollow part when the pressing rod is pressed against the sliding seat. In order to make the thin elastic sheet move smoothly in the second conveying channel, a gap is provided between the thin elastic sheet and the second conveying channel to prevent the thin elastic sheet from being stuck when moving in the second conveying channel. However, after the front thin elastic sheet is in place, the rear thin elastic sheet still has a tendency to move forward. Since the thin elastic sheet is thin, the rear thin elastic sheet may be inserted into the gap between the front thin elastic sheet and the second conveying channel, causing the second conveying channel to be blocked. The clamping part is used to pull the pressing rod when the second conveying channel is blocked, so that the pressing rod is separated from the sliding seat, thereby exposing the hollow part, facilitating the staff to dredge the second conveying channel, and improving the maintenance convenience of the second conveying channel.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1-8As shown, a zipper head assembly thin bullet catch mechanism, including feeding assembly 1, the feeding assembly 1 includes a first conveying channel 11, the first conveying channel 11 end is equipped with a hand component 2, the hand component 2 includes base 21, the base 21 is equipped with pressing plate 211, and drive unit 212 drives the pressing plate 211 to lift along the longitudinal direction; The base 21 is also transversely slidingly connected with sliding seat 23, the sliding seat 23 is equipped with longitudinally sliding vacuum suction rod 24; In the embodiment, the hand component 2 further includes adjusting plate 29, the adjusting plate 29 is equipped with adjusting hole vertically arranged. The adjusting plate 29 is used to adjust the height of the hand component 2, so that the hand component 2 can catch and release thin bullets on different models of pull head, which improves the compatibility of the hand component 2.

[0031] The lower end of the vacuum suction rod 24 is provided with a suction port for sucking the bullet; The vacuum suction rod 24 is located below the pressing plate 211, and the pressing plate 211 is in contact with or away from the vacuum suction rod 24; The lower end of the pressing plate 211 is also provided with a transmission member 22, which is used to convert the longitudinal lifting of the pressing plate 211 into the transverse movement of the sliding seat; The base 21 is provided with a second conveying channel 28, which is in communication with the first conveying channel 11, for receiving the bullets conveyed by the feeding assembly 1 for the vacuum suction rod 24 to suck; Because thin bullets are small, light and thin, it is easy to deform thin bullets by clamping, and thin bullets also have the characteristics of smooth surface, so the vacuum suction rod 24 can catch thin bullets without damaging them, improving the reliability of the hand component 2.

[0032] When the bullet is sucked by the vacuum suction rod 24; The pressing plate 211 is pressed down, first drives the sliding seat 23 to move transversely, and then presses the vacuum suction rod 24 to move down, to convey the bullet to the zipper head. By driving the pressing plate 211 and the transmission member 22 to drive the vacuum suction rod 24 and the sliding seat 23 respectively, the vacuum suction rod 24 moves in different directions under the drive of a single power source, saving the number of power sources and reducing the cost of the hand component 2.

[0033] In the embodiment, the transmission member 22 is provided with a first inclined surface 221 corresponding to the sliding seat 23, and the sliding seat 23 is provided with a second inclined surface 231 matched with the first inclined surface 221, and the first inclined surface 221 and the second inclined surface 231 are connected by inclined wedge to drive the sliding seat 23 to slide outward. By the inclined wedge connection of the first inclined surface 221 and the second inclined surface 231, the vertical motion of the transmission member 22 can be directly converted into horizontal motion, reducing the parts needed for motion conversion, and further reducing the complexity of the hand component 2 and improving the stability.

[0034] Specifically, a gap is arranged between the pressing plate 211 and the vacuum suction rod 24. When the transmission member 22 drives the sliding seat 23 to the position, the pressing plate 211 presses the vacuum suction rod 24 and drives the vacuum suction rod 24 to slide longitudinally. The gap is used to avoid the transmission member 22 and the pressing plate 211 driving the sliding seat 23 and the vacuum suction rod 24 to move simultaneously. When the transmission member and the pressing plate 211 drive the sliding seat 23 and the vacuum suction rod 24 simultaneously, the vacuum suction rod 24 will be directly pressed on the second conveying channel 28, which will cause the thin bullet to be damaged, and even cause the second conveying channel 28 to be damaged.

[0035] In the embodiment, the side surface of the vacuum suction rod 24 is provided with an air extraction hole 241 which is communicated with the suction port. The air extraction hole 241 is connected with an external vacuum extraction device through an air pipe. By arranging the air extraction hole 241 on the side surface of the vacuum suction rod 24, the air pipe is exposed outside the gripper assembly 2. When the vacuum suction rod 24 needs to be replaced, the air pipe can be quickly assembled and disassembled with the vacuum suction rod 24, which improves the maintenance convenience of the vacuum suction rod 24.

[0036] In the embodiment, the upper and lower end surfaces of the vacuum suction rod 24 are made of metal material. Since the upper end surface of the vacuum suction rod 24 frequently abuts against the transmission member 22, and the lower end frequently sucks the thin bullet, the upper and lower end surfaces of the vacuum suction rod 24 are easily worn. When the upper and lower end surfaces of the vacuum suction rod 24 are made of metal material, the wear degree of the upper and lower end surfaces of the vacuum suction rod 24 can be reduced, and the service life of the vacuum suction rod 24 is improved.

[0037] In the embodiment, the gripper assembly 2 further comprises first and second reset devices corresponding to the sliding seat 23 and the vacuum suction rod 24 respectively, and the first and second reset devices are drivingly connected with the sliding seat 23 and the vacuum suction rod 24 respectively. The first and second reset devices are respectively used to drive the sliding seat 23 and the vacuum suction rod 24 to reset, so as to ensure the repeated accuracy of the vacuum suction rod 24 when sucking the thin bullet each time, and the reliability of the gripper assembly 2 is improved.

[0038] In the embodiment, the first reset device 26 comprises a mounting base 261, a first elastic unit 263 and a pressing rod 262 in sliding connection with the mounting base 261, one end of the first elastic unit 263 is in abutment with the mounting base 261, and the other end is in elastic connection with the pressing rod 262, the pressing rod 262 is driven to press against the sliding base 23. Since the sliding base 23 is in wedge connection with the transmission member 22, when the transmission member 22 is reset, the sliding base 23 will not be automatically reset, the first elastic unit 263 drives the pressing rod 262 to press against the sliding base 23, so that the sliding base 23 is always in contact with the transmission member 22, when the transmission member 22 is reset, the sliding base 23 is reset synchronously, the repeated accuracy of the vacuum suction rod 24 when grabbing the thin bullet each time is improved, and the reliability of the gripper assembly 2 is improved.

[0039] Specifically, the mounting base 261 is L-shaped, the end of the pressing rod 262 penetrates through the mounting base 261 to form a clamping portion 2621. The second conveying channel 28 is provided with a hollow portion corresponding to the pressing rod 262, and the pressing rod 262 covers the hollow portion when the pressing rod 262 presses against the sliding base 23. In order to make the thin bullet move smoothly in the second conveying channel 28, a gap is provided between the thin bullet and the second conveying channel 28 to prevent the thin bullet from being stuck when moving in the second conveying channel 28, but after the front thin bullet is in place, the rear thin bullet still has a tendency to move forward. Since the thin bullet is thin, the rear thin bullet can be inserted into the gap between the front thin bullet and the second conveying channel 28, causing the second conveying channel 28 to be blocked. When the second conveying channel 28 is blocked, the clamping portion 2621 is used to pull the pressing rod 262, so that the pressing rod 262 is separated from the sliding base 23, and then the hollow portion is exposed, which facilitates the staff to dredge the second conveying channel 28, and improves the maintenance convenience of the second conveying channel 28.

[0040] In the embodiment, the second reset device comprises a second elastic unit 27, one end of the second elastic unit 27 is connected with the pressing plate 211, and the other end is in elastic connection with the vacuum suction rod 24. When the pressing plate 211 is reset, the vacuum suction rod 24 is driven to reset by the second elastic unit 27, so that the impact force received by the vacuum suction rod 24 when resetting is reduced, the wear of the vacuum suction rod 24 is reduced, and the service life of the vacuum suction rod 24 is improved.

[0041] Specifically, the gripper assembly 2 further comprises a limiting unit 25, the vacuum suction rod 24 is provided with a limiting rod 242 matched with the limiting unit 25, and the limiting rod 242 is in abutment with the limiting unit 25 after the second elastic unit 27 drives the vacuum suction rod 24 to reset. The limiting unit 25 and the limiting rod 242 are used to limit the reset position of the vacuum suction rod 24, and prevent the vacuum suction rod 24 from being in abutment with the pressing plate 211 directly under the driving of the second elastic unit 27, so that the distance between the vacuum suction rod 24 and the thin shell fragment is too large to suck the thin shell fragment, and the reliability of the gripper assembly 2 is improved.

[0042] According to the disclosure and teaching of the above description, those skilled in the art of the present application can also make changes and modifications to the above embodiments. Therefore, the present application is not limited to the specific embodiments disclosed and described above, and some modifications and changes of the present application should fall within the protection scope of the claims of the present application. In addition, although some specific terms are used in the specification, these terms are only for convenience of explanation and do not constitute any limitation on the present application.
