[0001] The invention relates to the technical field of spring buckle threading devices, and in particular to an automatic spring buckle threading machine. Background Art

[0002] Spring buckles are widely used accessories in the processing of outdoor clothing series such as jackets and luggage series products. When threading the spring rope through the spring buckle, it is usually necessary to squeeze the limiter by external force to make the limit hole flush with the threading hole, so as to facilitate the spring rope to pass through.

[0003] At present, when threading spring buckles, most of them are done by manually pressing and then threading the spring rope, which is not only inefficient and labor-intensive; but also the spring buckles are not large and need to be pressed by fingers to apply force, and long-term assembly production will cause discomfort to workers' fingers. Although, in order to solve the discomfort caused by manual pressing operations, pressing jigs are usually set up to replace manual pressing, but they also require manual auxiliary operations for loading and unloading, and in a short time, the efficiency is even lower than manual operation.

DETAILED DESCRIPTION

[0017] Example Combination Figures 1 to 7As shown, this embodiment provides an automated spring buckle threading machine, including a feeding device 6 for transmitting a spring buckle A to a positioning tool 17, a spring rope bracket 2 for storing a spring rope 25, a pressing mechanism 18 for pressing the spring buckle A placed on the positioning tool 17, and also includes a transmission mechanism arranged downstream of the spring rope bracket 2 for transmitting the spring rope 25 along a transmission channel, a spring rope cutting device 10 arranged at an appropriate position of the transmission channel, a turntable 16 connected to the positioning tool 17, an eccentric clamping claw 28 arranged downstream of the positioning tool 17, and a sensor 26 electrically connected to the turntable 16; The turntable 16 and the sensor 26 cooperate to rotate the spring buckle A to a position where the rope threading hole is aligned with the transmission channel; the eccentric clamp 28 can move along the transmission direction of the spring rope 25, and can drive one end of the spring rope 25 passing through the first rope threading hole A1 of the spring buckle A to rotate 180 degrees, and then pass through the second rope threading hole A2.

[0018] In this embodiment, specifically, Figures 1 to 3 As shown, the spring rope bracket 2 for storing the spring rope 25 is arranged on the base 1. The transmission mechanism includes a plurality of hollow wire feeding tubes erected on the base 1, and the wire feeding tubes form the transmission channel, through which the spring rope 25 is transmitted; the transmission mechanism also includes a plurality of wire feeding wheel groups, each of which includes two wire feeding rollers 3 that clamp the spring rope 25 and are driven to rotate by the first drive 4, and the first drive 4 is a motor. In this embodiment, two wire feeding wheel groups are included, the first wire feeding wheel group is arranged at the entrance of the first wire feeding tube 5; the second wire feeding wheel group is arranged between the first wire feeding tube 5 and the second wire feeding tube 8. In this embodiment, the wire feeding rollers 3 of the same group are all fixed with mutually meshing gears, one of which is connected to the motor by transmission, and the other group of wire feeding wheel groups is connected by transmission belt.

[0019] In this embodiment, the spring rope cutting device 10 is arranged between the second wire feeding tube 8 and the third wire feeding tube 9. It adopts a heat cutter, and heats the blade through a heating source, so that the blade of the heat cutter can melt the spring rope 25, so that the cut of the spring rope 25 has a cleaner cross section, reduces burrs and damage, and facilitates the spring rope 25 to pass through the spring buckle A.

[0020] In the present embodiment, the feeding device 6 is a vibration plate. The vibration plate is used to convey spring buckles A, and a spring buckle limit block 601 is provided on the vibration plate, so that the vibration plate can only sequentially output the spring buckles A facing upward, and the spring buckles A facing upward are all rebounded by the limit block 601 into the vibration plate and re-vibrated into spring buckles A facing upward for conveyance. A sequential feeding mechanism 7 is provided at the discharge port of the discharge channel of the feeding device 6, which includes a second drive 12, and 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 discharge channel each time, thereby realizing the discharge of one spring buckle A. Specifically, as Figure 6 As shown, the first baffle 13 and the second baffle 14 are spaced apart along a distance equal to the outer dimension of the spring buckle A, and a notch for the first baffle 13 and the second baffle 14 to pass through are respectively provided on the left and right sides of the side wall of the discharge channel, so that the first baffle 13 and the second baffle 14 can move back and forth along a discharge direction perpendicular to the discharge channel under the drive of the second drive 12; and when the first baffle 13 and the second baffle 14 are pulled back and forth once under the drive of the second drive 12, the feeding of the spring buckle A is realized.

[0021] Preferably, a third drive 15 is also included, which can be a cylinder, used to drive the positioning fixture 17 to move closer to or away from the discharge port so that the discharge port is flush with the positioning fixture 17, making it convenient for the spring buckle A to fall into the positioning fixture 17 smoothly.

[0022] And as Figure 8 and Fig. 9 As shown, the front of the spring buckle A has a first rope threading hole A1 and a second rope threading hole A2 for threading the spring rope 25; and the side has a through hole A4, and the edge of the through hole A4 is located outside the range of the rope threading hole. Therefore, in this embodiment, the sensor adopts a through-type photoelectric sensor 26, which is set at an appropriate position on the side so that its light can only pass through the edge of the through hole A4 and cannot pass through the rope threading hole, so as to cooperate with the turntable 16 to rotate the spring buckle A to the position where the rope threading hole is aligned with the transmission channel; specifically, the turntable 16 drives the spring buckle A to rotate, and when the light of the through-type photoelectric sensor 26 passes through the through hole A4, an instruction is immediately issued to stop the turntable 16 from rotating, and at this time, the rope threading hole of the spring buckle A is just aligned with the transmission channel. Under the transmission of the transmission mechanism, one end of the spring rope 25 can pass through the first rope threading hole A1.

[0023] In this embodiment, the pressing mechanism 18 is arranged above the positioning tool 17, which includes a pressing block 24 driven by a cylinder and capable of moving in a vertical direction. After the spring buckle A is loaded onto the positioning tool 17 and its position is adjusted, the pressing block 24 moves downward to press the spring button of the spring buckle A.

[0024] In this embodiment, a track 27 is provided on the base 1 , and the eccentric clamping jaw 28 can move along the track 27 under the drive of the fourth drive to approach or move away from the positioning tool 17 . The eccentric clamp 28 includes a first clamp 19 fixed on a turntable, and a second clamp 20 that can approach or move away from the first clamp 19 under the drive of the fifth drive; the turntable can rotate under the drive of the sixth drive; the operation process of the eccentric clamp 28 is as follows: when one end of the spring rope 25 passes through the first rope threading hole A1 and crosses the clamp for a certain length, the second clamp 20 approaches the first clamp 19 under the drive of the fifth drive, thereby clamping the spring rope 25, and then under the drive of the fourth drive, the eccentric clamp 28 clamps the spring rope 25 and moves a certain distance backward on the slide rail, and then under the drive of the sixth drive, one end of the spring rope 25 is rotated 180°, and then under the drive of the fourth drive, it moves close to the second rope threading hole A2, and then one end of the spring rope 25 is passed through the second rope threading hole A2 to complete the buckle. In this embodiment, the length of one end of the spring rope 25 passing through the first rope threading hole A1 and over the clamping jaw is set to 4-5 cm, and the spring rope 25 hardly sags due to the strong toughness of the spring rope 25; and driven by the fourth drive, the eccentric clamping jaw 28 clamps the spring rope 25 and moves back on the slide rail to a distance of 6-7 cm, which is convenient for the subsequent rotation of one end of the spring rope 25 by 180°. Of course, in other embodiments, the above-mentioned length setting and the distance of the back movement can be set according to the technical requirements of the buckle threading, for example, according to different materials and the thickness of the spring rope 25.

[0025] Preferably, the first clamping jaw 19 and the second clamping jaw 20 are semi-cylindrical with a certain length, which can effectively prevent the buckled end from being bent due to the influence of the rear end after rotating one end of the spring rope 25 by 180°.

[0026] Preferably, an arc-shaped baffle 21 is further provided on the turntable to prevent the spring rope 25 from being damaged due to excessive bending when the eccentric clamping jaw 28 rotates 180°.

[0027] In this embodiment, a trumpet-shaped channel is further provided between the eccentric jaw 28 and the positioning fixture 17, and its trumpet mouth faces one side of the eccentric jaw 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 fixedly provided on 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 following the pressing block 24 to approach or move away from the lower channel portion 23. The trumpet-shaped channel guides one end of the spring rope 25 after rotating 180°, so that the spring rope 25 can pass through the second rope threading hole A2. By dividing it into the upper channel portion 22 and the lower channel portion 23, it is convenient that after the buckle is threaded, the upper channel portion 22 can move up following the pressing block 24 to move away from the lower channel portion 23, so that the picking robot 29 can automatically remove the spring buckle A after the buckle is threaded.

[0028] The following is a detailed description of the entire automated buckle threading process: First, move the positioning fixture 17 to be flush with the discharge port of the vibration disk, then the vibration disk vibrates and rotates to feed, and the spring buckles A facing upward are arranged in a row for sequential feeding, and one of the spring buckles A is allowed to slide onto the positioning fixture 17 through the sequential feeding mechanism 7; then, 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 cooperates with the photoelectric sensor, and after the photoelectric sensor passes through the through hole A4 on the side of the spring buckle A, a command is issued to stop the rotating disk, at which time the rope threading hole is aligned with the transmission channel; then the cylinder above drives the pressure block 24 to press down the tight spring buckle A; at this time, the wire feeding wheel assembly starts The rope feeding operation starts, and when the head of one end of the spring rope 25 passes through the first rope threading hole A1 and extends out of the eccentric clamping jaw 284-5 cm, the clamping jaw clamps the spring rope 25 and moves a distance along the slide rail following the rope feeding speed; then the clamping jaw rotates 180° counterclockwise with one end of the spring rope 25, and the spring rope 25 cutting device 10 cuts off the spring rope 25; and after the clamping jaw rotates 180° counterclockwise, the eccentric clamping jaw 28 immediately drives one end of the spring rope 25 through the funnel-shaped pipe through the second rope threading hole A2, completing the buckle threading process, and then the pressing block 24 of the pressing mechanism 18 moves up and drives the upper part 22 of the channel to move up, and the picking robot 29 picks up the spring buckle A with the spring rope 25 threaded to complete the picking work.

[0029] The automated spring buckle threading machine can realize automatic transmission of the spring rope 25, automatic positioning of the spring buckle A, and cutting of the spring rope 25, and can rotate one end of the spring rope 25 passing through the first threading hole A1 of the spring buckle A by 180 degrees, and then pass it through the second threading hole A2 to realize the threading action, thereby realizing full automation of the entire threading work, improving production efficiency and reducing cost investment.
