Description

Technical Field

[0001] This utility model relates to the field of number tube processing technology, specifically to a laser marking mechanism for number tubes. Background Technology

[0002] In the industrial wire harness manufacturing field, number tubes are an important carrier for identifying electrical circuits. They are tubular labels used to identify materials such as wires, cables, and insulated cores, typically made of heat-shrinkable material. By printing numbers, specifications, and other information, they enable precise management of equipment and cables. Their core function is to ensure the correctness of wiring connections, facilitating construction, repair, and daily maintenance. Number tubes often have printed identification information, achieving accurate identification and efficient equipment and cable management. Traditional number tube printing usually uses thermal transfer technology to transfer ink from a ribbon to the surface of the number tube. This requires ribbon consumables and is suitable for complex graphics or small font sizes, offering high compatibility. However, due to the ease of wear and tear on the markings and the high cost of consumables, devices using laser marking to engrave number tubes have emerged on the market.

[0003] However, existing laser marking devices for number tubes are prone to problems such as misalignment and cross-entanglement when printing multiple number tubes simultaneously. The tubes are difficult to sort out, and after marking, the number tubes need to be clamped and positioned before being cut by a cutting mechanism. The marking process for number tubes is cumbersome and inefficient. This solution addresses this technical problem. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a laser marking mechanism for number tubes. A combing component combs multiple number tubes, preventing cross-entanglement and misalignment, making the transport of multiple number tubes more convenient and reliable. A fixture one or two positions the multiple number tubes, and a laser marking machine marks and prints the markings on these tubes, resulting in high marking efficiency. A traction cutting component simultaneously traction and cuts the multiple number tubes, further enhancing the efficiency of number tube transport and marking processing.

[0029] To more clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0030] See Figures 1-7 A laser marking mechanism for number tubes includes a base 1, and further includes a combing assembly 2, a traction cutting assembly 3 and a laser marking assembly 4 respectively disposed on the base 1, wherein a plurality of number tubes 5 pass through the combing assembly 2 and the traction cutting assembly 3 in sequence.

[0032] A support frame 11 is provided on the base 1. The traction unit 31 includes an active roller 311 and a driven roller 312 respectively rotatably mounted on the support frame 11, a motor 313 for driving the active roller 311 to rotate, a gear 314 at the other end of the active roller 311, and a gear 315 at the upper end of the driven roller 312. The motor 313 is mounted on the base 1. The gear 314 meshes with the gear 315. A number tube 5 is squeezed through between the active roller 311 and the driven roller 312.

[0033] One end of the drive roller 311 is provided with a first synchronous pulley 316, and the output end of the motor 313 is provided with a second synchronous pulley 317. A synchronous belt 318 is tensioned between the first synchronous pulley 316 and the second synchronous pulley 317.

[0034] The bracket 11 has adjustable blocks 319 at both ends that can be raised and lowered. The driven roller 312 is rotatably mounted on the adjustable blocks 319. The adjustable blocks 319 have internal threads. The top of the bracket 11 has a hand-tightening bolt 3191 for adjusting the position of the adjustable blocks 319. The hand-tightening bolt 3191 is threadedly connected to the adjustable blocks 319.

[0035] The platform 1 has two vertical supports 12, and a connecting plate 13 is provided between the two supports 12. The cutting unit 33 includes a fixed blade 331 provided on the connecting plate 13, a liftable blade holder 332 provided on the support 12, and a movable blade 333 provided on the blade holder 332. The number tube 5 passes through the space between the fixed blade 331 and the movable blade 333.

[0036] The cutting unit 33 also includes a second motor 334 mounted on the base 1. The output end of the second motor 334 is provided with a connecting block 335. A support roller 336 is eccentrically mounted on the connecting block 335. The cutter holder 332 is provided with a waist-shaped hole 3321. The support roller 336 is slidably mounted in the waist-shaped hole 3321.

[0037] The fixture unit 32 includes fixture one 321 and fixture two 322 for different types of number tubes 5 to pass through. The top sides of fixture one 321 and fixture two 322 are provided with opening slots 323 that allow laser etching of number tubes 5. Fixture one 321 and fixture two 322 limit different types of number tubes 5 so that different types of number tubes 5 can be marked by laser marking assembly 4 through the opening slots 323.

[0038] The combing component 2 includes a second support 21 mounted on the base 1, a plurality of distributing holes 22 arrayed at one end of the second support 21, and a first guide rod 23, a second guide rod 24, and a third guide rod 25 sequentially mounted on the second support 21. A plurality of isolation rings 26 for isolating two adjacent number tubes 5 are arrayed on the first guide rod 23 and the second guide rod 24. Each number tube 5 passes through the distributing hole 22, the first guide rod 23, the second guide rod 24, and the third guide rod 25 in sequence and then connects to the traction and cutting component 3.

[0039] The bracket 21 is equipped with an array of photoelectric sensors 27 for detecting the passage of the number tube 5. The photoelectric sensors 27 are electrically connected to the laser marking machine 42, motor 1 313 and motor 2 334 respectively through the controller. When the photoelectric sensors detect the passage of the number tube 5, the laser marking machine 42, motor 1 313 and motor 2 334 enter the running mode to perform the marking and conveying operations of the number tube.

[0040] The laser marking assembly 4 includes a support 3 41 vertically mounted on the base 1 and a laser marking machine 42 mounted on the support 3 41, with the laser marking machine 42 facing the fixture unit 32.

[0041] The support plate 43 is raised and lowerable on the bracket 3 41. The laser marking machine 42 is mounted on the support plate 43. The support plate 3 41 is equipped with a hand-cranked lifting mechanism 44. The support plate 43 is raised and lowered by the hand-cranked lifting mechanism 44, thereby adjusting the height of the laser marking machine 42 and thus adjusting the focus of the laser marking machine 42. The hand-cranked lifting mechanism 44 is implemented using existing technology and will not be described in detail.

[0042] The specific working process of this utility model:

[0043] In use, several number tubes 5 are sequentially passed through the material distribution hole 22, guide rod 1 23, guide rod 24 and guide rod 3 25 of the combing component 2, and then inserted into the fixture 1 321 of the fixture unit 32. Several isolation rings 26 are adjustablely set on guide rod 1 23 and guide rod 2 24 to guide and adjust the position of the number tubes 5. Then, the motor 1 313 is started. The synchronous wheel 2 317 on the motor 1 313 drives the synchronous wheel 1 316 to rotate through the synchronous belt 318, thereby driving the drive roller 311 to rotate. The drive roller 311 drives the driven roller 312 to rotate through the meshing rotation of gear 1 314 and gear 2 315. At this time, several number tubes 5 are inserted along the fixture 1 321 between the drive roller 311 and the driven roller 312. Under the squeezing and pulling action between the drive roller 311 and the driven roller 312, several number tubes 5 are pulled forward. Then the motor 1 313 stops rotating.

[0044] When the laser marking machine 42 of the laser marking assembly 4 is started, and the photoelectric sensor 27 on the second bracket 21 detects that a number tube 5 is passing through the corresponding material distribution hole 22, the laser marking machine 42 performs laser marking towards the opening slot 323 of the first fixture 321. After a section of the number tube 5 is marked, the first motor 313 is started again to pull the marked number tube 5 until the end of the section of the number tube 5 is pulled between the fixed blade 331 and the movable blade 333. Then the second motor 334 is started. The second motor 334 drives the support roller 336 to slide in the waist-shaped hole 3321 through the connecting block 335, so that the blade holder 332 drives the movable blade 333 to move upward. The number tube 5 is cut off by the shearing force of the fixed blade 331 and the movable blade 333. Then the movable blade 333 descends and stops. The first motor 313 is started again to pull the next section of the number tube 5. Then the laser marking machine 42 is used to mark the next section of the number tube 5 towards the first fixture 321.

[0045] The combing component 2 combs multiple number tubes 5, avoiding cross-entanglement and misalignment of the number tubes 5, making the transport of multiple number tubes 5 more convenient and reliable. The multiple number tubes 5 are positioned by fixture one 321 or fixture two 322, and the multiple number tubes 5 in fixture one 321 or fixture two 322 are marked and printed by laser marking machine 42, with high marking efficiency. The traction and cutting component 3 simultaneously traction and cuts multiple number tubes 5, with high transport and marking efficiency of number tubes 5.

[0046] The material distribution hole 22, guide rod 1 23, guide rod 24 and guide rod 3 25 in the combing component 2 play a combing and guiding role for the number tube 5, avoiding cross-entanglement when multiple number tubes 5 are marked at the same time. By adjusting the position of the isolation ring 26, the conveying position of the number tube 5 is adjusted, so that the number tube 5 can smoothly enter the fixture 1 321 or fixture 2 322, making the conveying of the number tube 5 safer and more reliable.

[0047] The number tube 5 is clamped and conveyed by the rotation of the active roller 311 and the driven roller 312. The pressure of the driven roller 312 on the number tube 5 is adjusted by hand-tightening the screw, making the clamping and traction of different types of number tubes 5 safer, more reliable, and more adaptable. The shearing force formed by the moving blade 333 and the fixed blade 331 driven by the motor 334 cuts the number tube 5. The cutting unit 33 has a simple and reliable structure, and the cutting of the number tube 5 is convenient and quick, improving the efficiency of marking the number tube 5.

[0048] The technical features of this utility model not described can be implemented by or by using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this utility model, and this utility model is not limited to the examples above.
