[0035] The present invention will be further described below in conjunction with the accompanying drawings.

[0036] Embodiment 1

[0037] like Figure 1 and Figure 2 As shown, the line number tube printing and sleeve-threading device of one embodiment of the present invention comprises a tube disc support 2, a conveying mechanism 3, a shearing mechanism 4, a printing mechanism 5, a tube supporting mechanism 6 and a manipulator 7 arranged in sequence, and the tube disc support 2 comprises a disc rack 23 for placing the line number tube. Figure 7 As shown, the tube supporting mechanism 6 includes a guide rod 67 for inserting into the line number tube, the guide rod 67 can position the line number tube output by the conveying mechanism 3 to the printing mechanism 5 for printing, the shearing mechanism 4 is used to cut the printed line number tube, and the manipulator 7 is used to clamp the cut line number tube and put it on the cable 1.

[0038] In this embodiment, the pipe reel bracket 2, conveying mechanism 3, shearing mechanism 4, printing mechanism 5, pipe supporting mechanism 6 and manipulator 7 arranged in sequence can respectively install, fix, convey, cut, print, support and thread the line number tube, so that the line number tube that is flattened and wound into a reel can be threaded on the cable 1 after printing and cutting through a series of processes, thereby realizing the automation of the printing and threading processing of the cable 1.

[0039] like Figure 3As shown, the tube reel bracket 2 also includes a support rod 21 and a horizontal axis 22. The horizontal axis 22 is arranged at the top of the support rod 21. A plurality of reels 23 are rotatably provided on the horizontal axis 22. Each reel 23 is used to place wire tubes of different specifications. The wire tubes of appropriate specifications can be selected according to the specifications of the cable 1 for printing and threading. There is no need to replace the wire tubes, which can improve work efficiency.

[0040] like Figure 4 As shown, the conveying mechanism 3 includes a base 31, a positioning groove 32, a driving motor 33 and two oppositely arranged pressing rollers 34. The positioning groove 32 and the pressing rollers 34 are respectively arranged on both sides of the base 31. The driving motor 33 is arranged on the base 31 and drives the pressing rollers 34. A pressing rod 35 is provided at one end of the positioning groove 32 away from the base 31, so that one end of the positioning groove 32 forms a strip hole for the wire tube on the disc rack 23 to enter, and the gap between the two pressing rollers 34 is arranged perpendicular to the strip hole. The wire tube is a plastic tube, which is rolled into a disc after being flattened to reduce its volume. Therefore, it is first necessary to open the flat wire tube to facilitate the processing of the wire tube. The flat wire tube can be inserted into the positioning groove 32 from the strip hole. Since the gap between the two pressing rollers 34 is arranged perpendicular to the strip hole, when the wire tube is rolled by the pressing roller 34, the pressing roller 34 will squeeze the folded edge of the wire tube, so that the end opening of the wire tube is open and shuttle-shaped.

[0041] The shearing mechanism 4 includes a pneumatic scissors 41, which are arranged on the base 31 and located on the side of the pressure roller 34 away from the base 31. The pneumatic scissors 41 can cut the line tube, and after cutting, the length of the line tube extending out of the pressure roller 34 is short, and no obvious sagging occurs. The end opening of the line tube is still facing the horizontal direction, which is convenient for the guide rod 67 in the tube support mechanism 6 to be inserted.

[0042] like Figure 3 As shown, the line number tube printing and sleeve-threading device of this embodiment further includes a translation bottom plate 8, and the tube disc support 2, the conveying mechanism 3 and the shearing mechanism 4 are all arranged on the translation bottom plate 8. Each disc rack 23 is provided with a corresponding conveying mechanism 3 and shearing mechanism 4, and the translation bottom plate 8 can be moved, so that the disc rack 23 with different specifications of line number tubes installed can be aligned with the printing mechanism 5 and the tube supporting mechanism 6, so as to realize the printing and sleeve-threading of different specifications of line number tubes.

[0043] like Figure 5 and Figure 6As shown, the printing mechanism 5 includes a marking machine 51 and a positioning assembly 52. ​​The positioning assembly 52 includes a lifting cylinder 521, a support plate 522 arranged on the lifting cylinder 521, and a positioning plate 523 arranged on the support plate 522. The support plate 522 is L-shaped, the positioning plate 523 is arranged horizontally, and a positioning hole 524 is opened on the positioning plate 523. The marking machine 51 is arranged above the positioning hole 524. The marking machine 51 in this embodiment is a laser marking machine. The initial position of the positioning plate 523 is located above the guide rod 67. When the guide rod 67 positions the line number tube below the positioning plate 523, the lifting cylinder 521 drives the positioning plate 523 to descend and contact the upper surface of the line number tube. Since there is a positioning hole 524 on the positioning plate 523, the marking machine 51 can print on the surface of the line number tube through the positioning hole 524. The guide rod 67 can provide a certain support effect, so that the surface of the line number tube to be printed is in a relatively flat state for easy printing.

[0044] Furthermore, the printing mechanism 5 also includes a camera 53 and a vacuum cleaner 54. The camera 53 is arranged on one side of the marking machine 51, and the vacuum cleaner 54 is arranged opposite to the marking machine 51. The camera 53 is used to detect whether the printed content and quality meet the requirements, and the vacuum cleaner 54 arranged opposite to the marking machine 51 is used to absorb dust generated during laser printing.

[0045] like Figure 7 and Figure 8 As shown, the pipe support mechanism 6 also includes a guide rail 61, a slider 62, a turntable 63, a telescopic cylinder 64, a mounting plate 65 and a plurality of support rods 66. The slider 62 is slidably arranged on the guide rail 61, the turntable 63 is arranged on the slider 62, the telescopic cylinder 64 is arranged on the turntable 63, the mounting plate 65 is rotatably arranged on the telescopic cylinder 64, and a plurality of support rods 66 are arranged on the mounting plate 65. Each support rod 66 is provided with a guide rod 67 at one end away from the mounting plate 65. The mounting plate 65 rotates to match the guide rods 67 and support rods 66 of corresponding specifications with the line number pipes to meet the support and positioning requirements of line number pipes of different specifications. The telescopic cylinder 64 realizes the movement of the support rod 66 and the guide rod 67 by extension and contraction. By setting the slider 62, the travel requirement of the telescopic cylinder 64 can be effectively reduced, and the guide rod 67 that is too long can be avoided to be easily bent. By setting the turntable 63, the support rod 66 and the guide rod 67 can rotate in the horizontal plane, and the line tube after printing is transferred to the side of the robot 7 for easy clamping by the robot 7. The robot 7 in this embodiment is a four-axis robot arm.

[0046] Furthermore, the end of the support rod 66 away from the mounting plate 65 is tapered. Since the wire gauge tube is not tightly sleeved on the guide rod 67, it is easy to fall off the guide rod 67 after the wire gauge tube is cut. Therefore, the support rod 66 needs to be inserted into the wire gauge tube and hold the wire gauge tube tightly to prevent the wire gauge tube from loosening during the transfer process. The end of the support rod 66 away from the mounting plate 65 is set to be tapered to facilitate the smooth insertion of the support rod 66 into the wire gauge tube. In addition, in order to prevent the pneumatic scissors 41 from cutting the guide rod 67 when cutting the wire gauge tube, the wire gauge tube also needs to be pulled out a certain distance before the cutting action is performed. This operation is achieved by contracting the telescopic cylinder 64. Therefore, it is also necessary to rely on the support rod 66 to hold the wire gauge tube tightly before the wire gauge tube can be pulled out.

[0047] Embodiment 2

[0048] like Fig. 9 As shown, an embodiment of the present invention also provides a method for printing and sleeve-threading a line number tube, comprising the following steps:

[0049] S1, the rolled line number pipe is installed on the pipe reel support 2, and the end opening of the line number pipe is in an open state after being rolled by two rollers 34 of the conveying mechanism 3;

[0050] S2, the slide block 62 in the pipe support mechanism 6 moves, so that the guide rod 67 is close to the end opening of the line number pipe, and the telescopic cylinder 64 is extended so that the guide rod 67 passes through the end opening of the line number pipe and is inserted into the interior of the line number pipe;

[0051] S3, the lifting cylinder 521 in the printing mechanism 5 contracts, causing the positioning plate 523 to descend and contact the upper surface of the line number tube, and the marking machine 51 prints on the line number tube through the positioning hole 524 on the positioning plate 523;

[0052] S4, the lifting cylinder 521 is extended to make the positioning plate 523 rise and reset, and the telescopic cylinder 64 is extended to make the end of the support rod 66 insert into the line number tube and tighten the line number tube;

[0053] S5, the telescopic cylinder 64 contracts, pulls the line number tube out of the set distance, and starts the shearing mechanism 4 to cut the line number tube;

[0054] S6, the slider 62 in the pipe supporting mechanism 6 moves, the turntable 63 rotates, and the pipe supporting mechanism 6 carries the line number pipe to the working area of ​​the manipulator 7;

[0055] S7, the robot 7 grabs the line tube and puts it on the cable 1.

[0056] The line number tube printing and sleeve threading method of this embodiment has a high degree of automation, and through the coordinated action of various mechanisms, the printing, cutting and sleeve threading processes of the line number tube can be efficiently completed.

[0057] Furthermore, after step S3, the camera 53 is used to detect whether the printed content is correct. If it is correct, the subsequent steps are performed. Otherwise, the cutting mechanism 4 is activated to cut off the line tube and discard it. By cutting off and discarding the line tube whose printed content does not meet the requirements, unqualified line tubes can be prevented from being put on the cable 1. The discarding operation of unqualified line tubes can also be performed by the robot 7. The robot 7 clamps the unqualified line tubes and places them at the designated recycling point for collection.
