The buckle needs to be clamped on a long line, such as Figure 1 As shown, under the action of external force, a pair of clamping parts are closed toward the buckle body, clamping the long line in the buckle, thereby realizing a fixed connection between the buckle and the long line. Summary of the invention

[0003] The technical problem solved by the present invention is to provide a set of mechanical structures for the matching and fixation of the long line and the buckle, so as to realize the automation of the matching and fixation of the long line and the buckle.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a mechanism for automatically loading, threading and tightening buckles, comprising a tightening assembly mechanism, a robot located next to the tightening assembly mechanism, the robot is provided with a long line loading clamp, the tightening assembly mechanism comprises a tightening device, a buckle supply device located next to the tightening device; the tightening device comprises a main fixture and a rotating disk, the main fixture is provided with a rotating disk clearance groove, the rotating disk clearance groove is connected with the feeding and conveying channel of the buckle supply device, the rotating disk is fitted in the rotating clearance groove, A buckle positioning groove is provided on the top of the rotating disk, and the depth of the buckle positioning groove is equal to or greater than the height of the buckle body; a first convex portion is provided on the side of the left end of the buckle positioning groove, and a second convex portion is provided on the side of the right end of the buckle positioning groove, the first convex portion and the second convex portion are respectively located on the front right sides of the buckle positioning groove, and the distance between the first convex portion and the second convex portion is equal to the distance between a pair of clamping parts on the buckle; a long-line fixing jaw is provided on the main fixture, and the long-line fixing jaw is distributed on the long-line positioning groove of the main fixture, and is located on both sides of the yield groove of the rotating disk.

[0005] The buckle supply device conveys the buckle to the buckle positioning groove of the rotating disk through the feeding conveying channel. When conveying the buckle, the buckle positioning groove is connected with the feeding conveying channel. Afterwards, driven by the robot, the long line feeding clamping claw obtains the long line from the long line material disk and transfers it to the main fixture. The long line is positioned in the long line positioning groove of the main fixture, and the long line is located on the upper surface of the rotating disk, perpendicular to the buckle. Since the depth of the buckle positioning groove is equal to or greater than the height of the buckle body, the notch of the buckle is fully or partially exposed above the rotating disk. Afterwards, a pair of long line fixing clamping claws clamp the long line, and the long line parts located on both sides of the rotating disk are clamped by the long line fixing clamping claws. Afterwards, the rotating disk rotates 90 degrees, driving the notch of the buckle to bite the long line on the rotating disk, so that the long line is clamped into the notch of the buckle, and the length direction of the long line coincides with the length direction of the buckle, and the angle between the long line and the buckle changes from the original 90 degrees to 0 degrees. The rotating disk continues to rotate, and the first convex portion and the second convex portion act on a pair of clamping parts of the buckle respectively, so that the pair of clamping parts are closed toward the buckle body, clamping the long line in the buckle, and realizing a fixed connection between the buckle and the long line.

[0006] The rotating disk is mounted on the rotating shaft of the first rotating cylinder, the first rotating cylinder is located below the rotating disk, and the first rotating cylinder is mounted on the bottom plate. The main fixture is mounted on the bottom plate through a pair of vertical plates.

[0007] The long-line fixed clamping jaw is installed on the first clamping jaw cylinder, the first clamping jaw cylinder is installed at the bottom of the main fixture, the main fixture is provided with a clamping jaw giving way groove, and the long-line fixed clamping jaw is located in the clamping jaw giving way groove.

[0008] The tensioning device also includes a wire pulling mechanism located on one side of the main fixture, the wire pulling mechanism includes a horizontal linear cylinder installed on the base plate, a slide seat connected to the horizontal linear cylinder, a wire pulling fixture arranged on the slide seat, a second clamping cylinder arranged on the wire pulling fixture, and a wire pulling clamp installed on the second clamping cylinder. The wire pulling fixture is provided with a long wire auxiliary positioning groove corresponding to the long wire positioning groove; when the wire pulling clamp clamps the long wire, the long wire fixing clamp located on the same side of the rotating disk's yield groove releases the long wire.

[0009] When the rotating disk rotates 90 degrees, the notch of the driving buckle bites the long wire on the rotating disk. After the long wire is clamped into the notch of the buckle, the long wire fixed jaw on the same side as the wire pulling jaw releases the long wire, and the long wire is clamped by the wire pulling jaw. At this time, the long wire is clamped by a long wire fixed jaw and a wire pulling jaw, and the long wire fixed jaw and the wire pulling jaw are respectively located on both sides of the rotating disk. Afterwards, driven by the horizontal linear cylinder, the wire pulling jaw has a tendency to move away from the rotating disk, and this tendency causes the part of the long wire that cooperates with the buckle to be tightened. The rotating disk continues to rotate in the original rotation direction, and the first protrusion and the second protrusion respectively act on a pair of clamping parts of the buckle. When the long wire is tightened, the pair of clamping parts are closed toward the buckle body, and the long wire is clamped in the buckle, realizing a fixed connection between the buckle and the long wire.

[0010] The number of the tensioning devices is a pair, and the pair of tensioning devices are distributed on both sides of the buckle supply device. The buckle supply device is provided with a feeding and conveying channel connected with the rotating disk yielding groove of the pair of tensioning devices. The pair of tensioning devices and the buckle supply device are installed on the rotating frame. The bottom of the rotating frame is connected to the rotating shaft of the second rotating cylinder. The second rotating cylinder is installed on the bottom bracket. An annular guide rail is fixed on the bottom bracket. The bottom of the rotating frame is provided with a rolling ball in contact with the annular guide rail.

[0011] In a pair of tensioning devices, one tensioning device is relatively close to the robot, and the other tensioning device is far away from the robot. When the robot transfers the long wire on the long wire tray to the main fixture of the tensioning device that is close to it, the tensioning device far away from the robot fixes the buckle to the long wire. After the manipulator takes away the long wire that has been fixed with the buckle from the tensioning device far away from the robot, the rotating frame rotates 180 degrees under the drive of the second rotating cylinder, and the unloaded tensioning device approaches the robot, while the tensioning device loaded with the long wire moves away from the robot. When the robot transfers the long wire on the long wire tray to the main fixture of the tensioning device that is close to it, the tensioning device far away from the robot fixes the buckle to the long wire. Repeating this process can improve production efficiency.

[0012] The long wire feeding clamp is driven by the third clamp cylinder, which is set on the long wire feeding template, and the long wire feeding template is connected to the execution end of the robot. Driven by the third clamp cylinder, the long wire feeding clamp grabs the long wire from the long wire feeding template, and driven by the robot, the long wire comes to the long wire positioning groove of the main fixture, and the long wire feeding clamp releases the long wire, and the long wire is positioned in the long wire positioning groove.

[0013] The present invention provides a mechanical structure for fixing clips on batches of long lines, and provides hardware support for the realization of production automation. BRIEF DESCRIPTION OF THE DRAWINGS

The main fixture 31 is provided with long-line fixing jaws 33 , which are distributed on the long-line positioning grooves 312 of the main fixture and are located on both sides of the rotating disk's clearance groove 311 .

[0037] Combination Figures 8 to 10 The rotating disk 32 is mounted on the rotating shaft of the first rotating cylinder 34 , the first rotating cylinder is located below the rotating disk, and the first rotating cylinder is mounted on the bottom plate 35 . The main fixture 31 is mounted on the bottom plate 35 through a pair of vertical plates 37 .

[0038] The long-line fixing clamp 33 is installed on the first clamp cylinder 36, and the first clamp cylinder is installed at the bottom of the main fixture 31. The main fixture is provided with a clamp yielding groove 313, and the long-line fixing clamp is located in the clamp yielding groove.

[0039] The tensioning device 30 also includes a wire pulling mechanism 40 located on one side of the main fixture 31, and the wire pulling mechanism includes a horizontal linear cylinder 41 installed on the base plate 35, a slide 42 connected to the horizontal linear cylinder, a wire pulling fixture 43 arranged on the slide, a second clamping cylinder 44 arranged on the wire pulling fixture, and a wire pulling clamp 45 installed on the second clamping cylinder. The wire pulling fixture is provided with a long wire auxiliary positioning groove 431 corresponding to the long wire positioning groove 312; when the wire pulling clamp clamps the long wire, the long wire fixing clamp 33 located on the same side of the rotating disk's yield groove 311 releases the long wire.

[0040] like Figure 6 , Figure 7The number of the tensioning devices 30 is a pair, and the pair of tensioning devices is distributed on both sides of the buckle supply device 50. The buckle supply device is provided with a feeding and conveying channel 51 connected with the rotating disk yielding groove 311 of the pair of tensioning devices. The pair of tensioning devices and the buckle supply device are installed on the rotating frame 60. The bottom of the rotating frame is connected to the rotating shaft of the second rotating cylinder 61. The second rotating cylinder is installed on the bottom bracket. The bottom bracket is fixed with an annular guide rail 62. The bottom of the rotating frame is provided with a rolling ball 63 in contact with the annular guide rail.

[0041] like Figure 4 The long line feeding clamp 21 is driven by a third clamp cylinder 22 , and the third clamp cylinder is arranged on a long line feeding template 23 , and the long line feeding template is connected to the execution end of the robot 20 .

[0042] refer to Figure 3 , Figure 5 , in a pair of tensioning devices 30, one tensioning device is relatively close to the robot 20, and the other tensioning device is far away from the robot. When the robot transfers the long wire on the long wire tray 81 to the main fixture 31 of the tensioning device that is close to it, the tensioning device far away from the robot 20 fixes the buckle 90 to the long wire 80. After the manipulator takes away the long wire that has been fixed with the buckle from the tensioning device far away from the robot, the rotating frame 60 rotates 180 degrees under the drive of the second rotating cylinder 61, and the unloaded tensioning device approaches the robot, while the tensioning device loaded with the long wire moves away from the robot. When the robot transfers the long wire 80 on the long wire tray 81 to the main fixture 31 of the tensioning device that is close to it, the tensioning device far away from the robot fixes the buckle 90 to the long wire 80. Repeat this process.

[0043] Among them, reference Figure 4 , Figure 5 The robot 20 transfers the long wire on the long wire material tray 81 to the main fixture 31 of the nearby tensioning device. The working principle is: under the drive of the third clamping cylinder 22, the long wire loading clamp 21 clamps the long wire 80 from the long wire loading template 81. Under the drive of the robot 20, the long wire comes to the long wire positioning groove 312 of the main fixture, and the long wire loading clamp releases the long wire, and the long wire is positioned in the long wire positioning groove.

[0044] Among them, reference Figures 6 to 12, the working principle of the tensioning device 30 fixing the buckle 90 on the long wire 80 is as follows. The buckle supply device 50 using a vibrating disk conveys the buckle 90 to the buckle positioning groove 321 of the rotating disk 32 through the feeding and conveying channel 51. When conveying the buckle, the buckle positioning groove is connected with the feeding and conveying channel 51. Afterwards, under the drive of the robot 20, the long wire loading clamp 21 positions the long wire 80 in the long wire positioning groove 312 of the main fixture, and the long wire is located on the upper surface of the rotating disk 32, perpendicular to the buckle 90. Since the depth of the buckle positioning groove 321 is equal to or greater than the height of the buckle body 91, the notch 93 of the buckle is fully or partially exposed above the rotating disk 32. Afterwards, a pair of long wire fixing clamps 33 clamp the long wire 80, and the long wire parts located on both sides of the rotating disk 32 are clamped by the long wire fixing clamps. Afterwards, the rotating disk 32 rotates 90 degrees, driving the notch 93 of the buckle to engage the long wire 80 on the rotating disk 32, so that the long wire is clamped into the notch of the buckle. The long wire fixed jaw 33 on the same side as the wire pulling jaw 45 releases the long wire 80, and the long wire is clamped by the wire pulling jaw 45. At this time, the long wire 80 is clamped by a long wire fixed jaw 33 and a wire pulling jaw 45, and the long wire fixed jaw and the wire pulling jaw are respectively located on both sides of the rotating disk 32. Afterwards, under the drive of the horizontal linear cylinder 41, the wire pulling jaw 45 has a tendency to move away from the rotating disk 32, and this tendency causes the long wire portion that cooperates with the buckle 90 to be tightened. The rotating disk 32 continues to rotate along the original rotation direction, and the first protrusion 322 and the second protrusion 323 respectively act on a pair of clamping parts 92 of the buckle. When the long line is tightened, the pair of clamping parts 92 are closed toward the buckle body 91, and the long line 80 is clamped in the buckle 90, thereby realizing a fixed connection between the buckle and the long line.
