[0034] In the embodiment, as shown in Figures 1 to 3 The transmission mechanism includes a plurality of hollow wire feeding pipes arranged on the base 1, which form the transmission channel through which the spring rope 25 is transmitted; the transmission mechanism further includes a plurality of wire feeding wheel sets, each of which includes two wire feeding rollers 3 clamping the spring rope 25 and rotating under the drive of a first drive 4, which is a motor. In the embodiment, there are two wire feeding wheel sets, the first wire feeding wheel set is arranged at the inlet of the first wire feeding pipe 5, and the second wire feeding wheel set is arranged between the first wire feeding pipe 5 and the second wire feeding pipe 8. In the embodiment, the wire feeding rollers 3 in the same set are fixedly provided with gears that mesh with each other, one of the wire feeding rollers 3 is in transmission connection with the motor, and the other wire feeding wheel set is in transmission connection through a transmission belt.

[0035] In the embodiment, the spring rope cutting device 10 is arranged between the second wire feeding pipe 8 and the third wire feeding pipe 9. The device is a hot cutting machine, which can melt the spring rope 25 by heating the blade with a heating source, so as to make the cutting surface of the spring rope 25 at the cutting position more clean, reduce burrs and damage, and facilitate the spring rope 25 to pass through the spring buckle A.

[0036] In the embodiment, the feeding device 6 is a vibrating disc. The vibrating disc is used to feed the spring buckle A and is provided with a spring buckle limiting block 601, so that the vibrating disc can only sequentially output the spring buckle A with the front face upward, and the spring buckle A with the back face upward is bounced back into the vibrating disc by the limiting block 601 to be vibrated into the spring buckle A with the front face upward again for feeding. The discharging opening of the discharging channel of the feeding device 6 is provided with a sequential feeding mechanism 7, which includes a second drive 12, a first baffle 13 and a second baffle 14; the second drive 12 drives the first baffle 13 and the second baffle 14 to move back and forth on the discharging channel once, so as to realize the feeding of one spring buckle A. Specifically, as shown in Figure 6As shown, the first baffle 13 and the second baffle 14 are spaced apart by a distance of one outer dimension of the spring buckle A, and the left and right sides of the side wall of the discharge channel are respectively provided with a notch for the first baffle 13 and the second baffle 14 to pass through, so that the first baffle 13 and the second baffle 14 can be moved back and forth along a direction perpendicular to the discharge direction of the discharge channel under the driving of the second drive 12; and when the first baffle 13 and the second baffle 14 are pulled back and forth once under the driving of the second drive 12, the feeding of one spring buckle A is realized.

[0037] Preferably, a third drive 15, which can be a pneumatic cylinder, is further included for driving the positioning tool 17 to approach or move away from the discharge port, so that the discharge port is flush with the positioning tool 17, facilitating the smooth falling of the spring buckle A into the positioning tool 17.

[0038] As shown, Figure 8 and Figure 9 As shown, the front surface of the spring buckle A has a first rope passing hole A1 and a second rope passing hole A2 for the spring rope 25 to pass through, and the side surface has a through hole A4, and the edge portion of the through hole A4 is located outside the range of the rope passing hole. Therefore, in the embodiment, the sensor adopts a reflection type photoelectric sensor 26, which is arranged at an appropriate position on the side surface, so that the light thereof can only pass through the edge portion of the through hole A4 and cannot pass through the rope passing hole, thereby cooperating with the rotating disc 16 to rotate the spring buckle A to a position where the rope passing hole is aligned with the transmission channel; specifically, when the light of the reflection type photoelectric sensor 26 passes through the through hole A4, the rotating disc 16 is instructed to stop rotating, and at this time, the rope passing hole of the spring buckle A is aligned with the transmission channel. One end of the spring rope 25 can pass through the first rope passing hole A1 under the transmission of the transmission mechanism.

[0039] In the embodiment, the pressing mechanism 18 is arranged above the positioning tool 17 and includes a pneumatic cylinder driving a pressing block 24 that can move in a vertical direction, and after the spring buckle A is fed onto the positioning tool 17 and is adjusted to the correct position, the pressing block 24 moves downward to press the spring button of the spring buckle A.

[0040] In the embodiment, the base 1 is provided with a track 27, and the eccentric clamping jaw is moved along the track 27 under the driving of the fourth drive to approach or move away from the positioning tool 17. The eccentric clamping jaw comprises a first clamping jaw 19 fixed on a rotating table, and a second clamping jaw 20 which can approach or move away from the first clamping jaw 19 under the driving of a fifth drive; the rotating table can be rotated under the driving of a sixth drive; the operation process of the eccentric clamping jaw is as follows: when one end of the spring rope 25 passes through the first rope passing hole A1 and exceeds the clamping jaw by a certain length, the second clamping jaw 20 approaches the first clamping jaw 19 under the driving of the fifth drive, so as to clamp the spring rope 25, then the eccentric clamping jaw clamps the spring rope 25 and moves a certain distance behind the slide rail under the driving of the fourth drive, then the sixth drive rotates the one end of the spring rope 25 by 180°, and then the fourth drive moves to approach the second rope passing hole A2, so as to pass the one end of the spring rope 25 through the second rope passing hole A2 to complete the buckling. In the embodiment, the length by which the one end of the spring rope 25 exceeds the clamping jaw after passing through the first rope passing hole A1 is set to 4-5 cm, and the length is almost not sagged under the strong toughness of the spring rope 25; and the distance by which the eccentric clamping jaw clamps the spring rope 25 and moves behind the slide rail under the driving of the fourth drive is set to 6-7 cm, so as to facilitate the rotation of the one end of the spring rope 25 by 180°. Of course, in other embodiments, the above length and the distance of movement can be set according to the technical requirements of buckling, for example, according to different materials and the thickness of the spring rope 25.

[0041] Preferably, the first clamping jaw 19 and the second clamping jaw 20 are semicylindrical with a certain length, which can effectively avoid the situation that the buckling end of the spring rope 25 is bent after being rotated by 180°.

[0042] Preferably, the rotating table is further provided with an arc-shaped baffle 21, which can prevent the spring rope 25 from being damaged due to excessive bending when being rotated by 180° with the eccentric clamping jaw.

[0043] In this embodiment, a trumpet-shaped channel is provided between the eccentric gripper 28 and the positioning fixture 17, with its flared opening facing the eccentric gripper 28. The trumpet-shaped channel is divided into an upper channel portion 22 and a lower channel portion 23 along its axis; the lower channel portion 23 is fixed to the base 1; the upper channel portion 22 is connected to the pressing block 24 of the pressing mechanism 18 and can move up and down with the pressing block 24 to move closer to or away from the lower channel portion 23. The trumpet-shaped channel guides one end of the spring rope 25 after it has been rotated 180°, facilitating the passage of the spring rope 25 through the second rope-threading hole A2. Dividing it into the upper channel portion 22 and the lower channel portion 23 allows the upper channel portion 22 to move upwards with the pressing block 24 after the buckle is threaded, thus moving away from the lower channel portion 23, facilitating the automatic removal of the spring buckle A by the picking robot arm 29 after the buckle is threaded.

[0044] The following details the entire automated fastening process:

[0045] First, the positioning fixture 17 is moved to be flush with the discharge port of the vibratory feeder. Then, the vibratory feeder rotates and vibrates to feed the spring buckles A in a row, with the front-facing spring buckles A being fed sequentially. The sequential feeding mechanism 7 allows one spring buckle A to slide onto the positioning fixture 17. Next, the positioning fixture 17 is lowered to a height where the rope threading hole is flush with the transmission channel. Then, the turntable 16 drives the spring buckle A to rotate and, in conjunction with the photoelectric sensor, sends a command to stop the turntable after the photoelectric sensor passes through the through hole A4 on the side of the spring buckle A. At this point, the rope threading hole is aligned with the transmission channel. Then, the cylinder above drives the pressure block 24 to press down on the spring buckle A. At this time, the wire feeding wheel... The group begins feeding the rope. When one end of the spring rope 25 passes through the first rope-feeding hole A1 and extends 4-5 cm beyond the eccentric gripper, the gripper clamps the spring rope 25 and moves a distance along the slide rail following the rope feeding speed. Then, the gripper rotates one end of the spring rope 25 counterclockwise by 180°, and the spring rope 25 cutting device 10 cuts the spring rope 25. After the gripper rotates 180° counterclockwise, the eccentric gripper immediately drives one end of the spring rope 25 through the funnel-shaped pipe through the second rope-feeding hole A2, completing the buckle-feeding process. Then, the pressing block 24 of the pressing mechanism 18 moves upward and drives the upper part 22 of the channel to move upward. The picking robot 29 picks up the spring buckle A with the spring rope 25 threaded through it, completing the picking work.

[0046] The automatic spring buckle threading machine can realize automatic transmission of the spring rope 25, automatic positioning of the spring buckle A, cutting of the spring rope 25, and rotating the one end of the spring rope 25 through the first threading hole A1 of the spring buckle A by 180 degrees, and then threading out from the second threading hole A2 to realize the threading buckle action, and realize the full automation of the whole threading buckle work, and improve the production efficiency and reduce the cost investment.
