Description

Technical Field

[0001] The utility model relates to the technical field of automobile wiring harness coding, in particular to laser coding equipment for wiring harnesses. Background Art

[0002] As the connection component that connects various electrical devices in the automotive circuit, the wiring harness usually needs to be marked on its surface after it is formed during the production process. This is to achieve the purpose of marking the model or related parameters of the wiring harness, realize the effective traceability of subsequent products, and help manufacturers track and manage various types of wiring harnesses more conveniently during the production and maintenance process. It is also of great significance for fault diagnosis, repair and after-sales service.

[0003] Currently, when marking the surface of automotive wiring harnesses, the laser coding device is mainly placed above the surface of the wiring harness to achieve the coding operation. For example, in the prior art with patent application number CN202220347744.0, a laser coding machine for wires and cables is disclosed. Its main structure includes a base and a first motor. Feeding components are provided on both sides of the top of the base. The top of the base is connected to a housing. The top of the housing is connected to a cabinet. The outer surface of the cabinet is connected to a window. A laser coding device is installed above the interior of the cabinet. A cleaning component is provided inside the cabinet. It also includes roller structures provided on the left and right sides of the laser coding device.

[0004] It can be seen that the above-mentioned inkjet printer mainly relies on the guidance of rollers on both sides to restrain the wire harness during transportation, and then uses the laser inkjet printer to spray the code downward to achieve the purpose of spraying the mark on the surface of the wire harness. However, this inkjet printer has the following defects in the actual inkjet printing process:

[0005] Since the horizontal moving section of the finished wire harness cable is long and the diameter is thin, when the finished wire harness cable is pulled and moved, it often produces a small amplitude vibration, which will cause the marking code sprayed by the nozzle to deviate from the wire harness cable during coding, and then the marking code sprayed by the nozzle will be discontinuous or cannot be sprayed on the axis of the cable.

[0006] Based on this, the utility model improves and constrains the problems existing in the prior art during the laser coding of slender wire harnesses and cables, and specially proposes a laser coding device with a guiding constraint function specifically for long-distance wire harness coding, so as to better solve the problems existing in the prior art.

DETAILED DESCRIPTION

[0032] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the present invention's technical solution and are therefore only examples and are not intended to limit the scope of protection of the present invention. Figures 1-9 As shown in .

[0033] Example 1: A laser coding device for a wiring harness comprises a ground seat 1 fixed on the ground, a hanging top seat 2 fixedly suspended and installed directly above the ground seat 1, a laser coding machine 3 fixedly installed at the bottom center of the hanging top seat 2, ground cylinder groups installed on the tops of the left and right sides of the ground seat 1, a lower constraint guide unit installed on each of the ground cylinder groups, the two lower constraint guide units are arranged opposite to each other and the center planes are arranged coplanarly, and upper constraint guide units are respectively provided on the top cylinder groups fixedly connected above each of the lower constraint guide units, and each of the upper constraint guide units circumferentially constrains the wiring harness cable 4 to be coded passing through the two by cooperating with the lower constraint guide unit below it.

[0034] It should be noted that: when the laser coding equipment of the wire harness in the present invention is in use, one end of the wire harness cable 4 is passed through the space formed by the upper constraint guide unit and the lower constraint guide unit below the laser coding machine 3 from left to right, and then relies on the downstream traction machine to continuously pull the current wire harness cable 4 downstream. In the process of the wire harness cable 4 being pulled, the upper constraint guide unit and the lower constraint guide unit are controlled to move up and down to effectively ensure the tightness of the constraint guide of the current wire harness cable 4, so that it keeps matching the outer diameter of the current wire harness cable 4.

[0035] When the wiring harness cable 4 is being pulled, the wiring harness cable 4 section passing through the upper constraint guide unit and the lower constraint guide unit is supported on both sides, thereby effectively reducing the frequent and large-scale vibrations during the pulling process, thereby ensuring the accuracy of coding using the laser inkjet printer 3.

[0036] In any of the above schemes, it is preferred that the two upper constraint guide units are symmetrically arranged with respect to the central vertical plane of the laser inkjet printer 3 , and the two lower constraint guide units are symmetrically arranged with respect to the central vertical plane of the laser inkjet printer 3 .

[0037] The upper constraint guide unit and the lower constraint guide unit respectively provided on the left and right sides of the laser inkjet printer 3 can serve the purpose of circumferentially constraining the wiring harness cable 4 .

[0038] In any of the above schemes, it is preferred that the lower constraint and guide unit includes a horizontally arranged bottom translation cylinder 5, the cylinder barrel of the bottom translation cylinder 5 is fixedly mounted on the top of the ground-connecting cylinder group, and a lower translation seat 6 is fixedly mounted on the inner end of the piston rod of the bottom translation cylinder 5, and two lower constraint sleeves 7 are fixedly mounted on the top of the lower translation seat 6 along its front-to-back direction, and lower side guides 8 are respectively provided above the two lower constraint sleeves 7, and the bottom of each lower side guide 8 is movably inserted in the inner cavity of the lower constraint sleeve 7, and a horizontally arranged bottom telescopic guide A is provided above the ground-connecting seat 1 between the two lower side guides 8, and a lower U-shaped space 10 for the wiring harness cable 4 to pass through is formed between the bottom telescopic guide A and the two lower side guides 8, and the bottom and both side outer walls of the wiring harness cable 4 to be coded respectively abut against the top of the bottom telescopic guide A and the side walls of each lower side guide 8 at their corresponding positions.

[0039] It should be noted that: the lower constraint guide unit as a whole relies on the lifting and lowering of the ground cylinder group to control the height position of the entire structure, so as to achieve the purpose of matching different outer diameters of the wiring harness cables 4. When the ground cylinder group is lifted and lowered into place, controlling the extension and retraction of the bottom translation cylinder 5 can drive it to extend and retract along the traction direction of the wiring harness cables 4. Controlling the relative or opposite movement of the bottom translation cylinders 5 on both sides can change the spacing distance between the lower guide members 8 and the bottom telescopic guide members A on both sides, thereby changing the spacing size between the guided support parts at both ends of the wiring harness cables 4 in the middle, reducing its downward drooping amplitude, and thus reducing the amplitude of up and down vibrations during traction.

[0040] Controlling the extension or contraction of the bottom telescopic guide A can control the lateral size of the lower U-shaped space 10 , thereby achieving the purpose of quickly adjusting to match the outer diameter of the current wiring harness cable 4 .

[0041] In any of the above schemes, it is preferred that the upper constraint guide unit includes a horizontally arranged top translation cylinder 11, the cylinder barrel of the top translation cylinder 11 is fixedly installed at the bottom of the top cylinder group, and an upper translation seat 12 is fixedly installed at the inner end of the piston rod of the top translation cylinder 11, and two mounting bottom holes 13 are respectively arranged at intervals at the bottom of the upper translation seat 12, and a bottom connecting seat 14 is bolted and fixed to the bottom of the upper translation seat 12, and two upper constraint pipe sleeves 15 are respectively fixed on both sides of the bottom of the bottom connecting seat 14, and the inner cavity of each upper constraint pipe sleeve 15 is respectively connected to the inside of the corresponding mounting bottom hole 13 to form a T-shaped stepped circle. Hole 16, and an upper guide piece 9 coaxially arranged therewith is movably fitted and clamped below the two lower restraining sleeves 7. The top of each upper guide piece 9 is movable and coaxially clamped and inserted in the T-shaped stepped circular hole 16 of the lower restraining sleeve 7. A horizontally arranged top telescopic guide piece B is provided below the suspension top seat 2 between the two upper guide pieces 9. An upper U-shaped space 17 for the wiring harness cable 4 to pass through is formed between the top telescopic guide piece B and the two upper guide pieces 9. The top and both side outer walls of the wiring harness cable 4 to be coded respectively abut against the bottom of the top telescopic guide piece B and the side walls of each upper guide piece 9 at their corresponding positions.

[0042] Similarly, it should be noted that the upper constraint guide unit as a whole relies on the lifting and lowering of the top cylinder group to control the height position of the entire structure, so as to achieve the purpose of matching different outer diameters of the wiring harness cables 4. When the top cylinder group is lifted and lowered into place, controlling the extension and retraction of the top translation cylinder 11 can drive it to extend and retract along the traction direction of the wiring harness cables 4. Controlling the relative or opposite movement of the top translation cylinders 11 on both sides can change the spacing distance between the upper guide members 9 and the top telescopic guide members B on both sides, thereby changing the spacing size between the guided support parts at both ends of the wiring harness cables 4 in the middle, reducing its downward drooping amplitude, and thus reducing the amplitude of up and down vibrations during traction.

[0043] Controlling the extension or contraction of the top telescopic guide B can control the lateral size of the upper U-shaped space 17 , thereby achieving the purpose of quickly adjusting to match the outer diameter of the current wiring harness cable 4 .

[0044] In any of the above schemes, it is preferred that the ground cylinder group is composed of two lower lifting electric cylinders 18 arranged at intervals, the bottom of the cylinder barrel of each lower lifting electric cylinder 18 is fixed to the top of the ground connecting seat 1, and the top of the piston rod of each lower lifting electric cylinder 18 is fixed to the bottom of the bottom translation cylinder 5.

[0045] The lifting of the ground cylinder group can drive the lifting of the components installed on the top by controlling the synchronous extension of the two lower lifting electric cylinders 18, thereby controlling the overall lifting into place.

[0046] In any of the above schemes, it is preferred that the top cylinder group is composed of two upper lifting electric cylinders 19 arranged at intervals, the top of the cylinder barrel of each upper lifting electric cylinder 19 is fixed to the top of the suspension top seat 2, and the bottom of the piston rod of each upper lifting electric cylinder 19 is fixed to the top of the top translation cylinder 11.

[0047] The lifting of the top cylinder group can drive the lifting of the components installed on the top by controlling the synchronous extension of the two upper lifting electric cylinders 19, thereby controlling the overall lifting into place.

[0048] Example 2: Compared with Example 1, this example also includes the following technical features:

[0049] In any of the above schemes, it is preferred that the lower side guide member 8 includes two vertically arranged lower vertical shafts 801, the lower ends of the lower vertical shafts 801 are movably inserted in the inner cavity of the lower restraining sleeve 7, and a lower rubber guide roller 802 is coaxially movably sleeved on the middle outer wall of the lower vertical shaft 801, and the outer wall of the lower rubber guide roller 802 is used to abut against the outer wall of the wiring harness cable 4 to be coded.

[0050] When guiding, the lower guide member 8 mainly relies on the lower vertical shaft 801 to realize fixed-axis rotation in the inner cavity of the lower constraint sleeve 7. At the same time, since the lower rubber guide roller 802 is fitted on the outer wall of the lower vertical shaft 801, when the outer wall of the lower rubber guide roller 802 abuts against the outer wall of the wiring harness cable 4, the lower rubber guide roller 802 can rotate under the action of external traction and play a guiding role.

[0051] In any of the above schemes, it is preferred that the bottom telescopic guide A includes a horizontally arranged bottom horizontal double-axis telescopic cylinder 20, and the piston rods at both ends of the bottom horizontal double-axis telescopic cylinder 20 are respectively movably connected to the outer side walls of the lower vertical shaft 801 at their corresponding positions, and a bottom rubber guide roller 21 is movably connected to the middle outer side wall of the cylinder barrel of the bottom horizontal double-axis telescopic cylinder 20, and the top of the outer side wall of the bottom rubber guide roller 21 is used to abut against the outer side wall of the wiring harness cable 4 to be coded.

[0052] The bottom telescopic guide A mainly controls the extension and contraction of the piston rods at both ends of the bottom horizontal dual-axis telescopic cylinder 20 to drive the spacing distance between the lower guide members 8 at their corresponding positions, thereby effectively achieving the purpose of rapid adjustment according to the outer diameter of the current wiring harness cable 4.

[0053] When the wiring harness cable 4 passes through the top of the bottom rubber guide roller 21 , the fixed-axis rotation of the bottom rubber guide roller 21 can play a certain guiding and restraining role under the action of friction.

[0054] In any of the above schemes, it is preferred that the upper guide member 9 includes two vertically arranged upper vertical shafts 901, the upper ends of the upper vertical shafts 901 are movably inserted in the inner cavity of the upper constraint sleeve 15, and a contact plate 902 is coaxially fixed to the top of the upper vertical shaft 901, and the contact plate 902 is cooperatively inserted in the mounting bottom hole 13 at the top of the T-shaped stepped circular hole 16. The outer diameter of the contact plate 902 is larger than the inner diameter of the vertical section of the T-shaped stepped circular hole 16, and an upper rubber guide roller 903 is coaxially movably sleeved on the middle outer wall of the upper vertical shaft 901, and the outer wall of the upper rubber guide roller 903 is used to contact the outer wall of the wiring harness cable 4 to be coded.

[0055] When guiding, the upper guide member 9 mainly relies on the upper vertical shaft 901 to realize fixed-axis rotation in the inner cavity of the upper constraint sleeve 15. At the same time, since the upper rubber guide roller 903 is fitted on the outer wall of the upper vertical shaft 901, when the outer wall of the upper rubber guide roller 903 abuts against the outer wall of the wiring harness cable 4, the upper rubber guide roller 903 can rotate under the action of external traction and play a guiding role.

[0056] In any of the above schemes, it is preferred that the top telescopic guide member B includes a horizontally arranged top horizontal double-axis telescopic cylinder 22, and the piston rods at both ends of the top horizontal double-axis telescopic cylinder 22 are respectively movably connected to the outer side walls of the upper vertical shaft 901 at their corresponding positions, and a top rubber guide roller 23 is movably connected to the middle outer side wall of the cylinder barrel of the top horizontal double-axis telescopic cylinder 22, and the bottom of the outer side wall of the upper rubber guide roller 903 is used to abut against the outer side wall of the wiring harness cable 4 to be coded.

[0057] The top telescopic guide B mainly controls the extension and contraction of the piston rods at both ends of the top horizontal dual-axis telescopic cylinder 22 to drive the spacing distance between the upper guide members 9 at their corresponding positions, thereby effectively achieving the purpose of rapid adjustment according to the outer diameter of the current wiring harness cable 4.

[0058] When the wiring harness cable 4 passes through the bottom of the upper rubber guide roller 903 , the top rubber guide roller 23 can rotate along a fixed axis to play a certain guiding and restraining role under the action of friction.

[0059] Specific working principle: The equipment is powered on before use. When in use, one end of the wiring harness cable 4 is passed from left to right through the space formed by the upper constraint guide unit and the lower constraint guide unit below the laser inkjet printer 3, and then the downstream traction machine is used to continuously pull the current wiring harness cable 4 downstream.

[0060] During the pulling process of the wire harness cable 4, the upper and lower constraint guide units are controlled to move up and down, which effectively ensures that the tightness of the constraint guide on the current wire harness cable 4 matches the outer diameter of the current wire harness cable 4. During the pulling process of the wire harness cable 4, the wire harness cable 4 section passing through the upper and lower constraint guide units is supported on both sides, which effectively reduces frequent and large-scale vibrations during the pulling process, ensuring the accuracy of the coding by the laser inkjet printer 3.

[0061] From the above, it can be seen that the laser coding equipment of the present wiring harness can guide the wiring harness cable 4 passing under the laser coding machine 3 under the cooperation of the upper constraint guide unit and the lower constraint guide unit when coding the wiring harness cable 4, reduce the vibration amplitude of the cable during the dragging and traction process, and effectively play the role of circumferential constraint; by reasonably controlling the lifting height of the adjacent upper constraint guide unit and the lower constraint guide unit, it is possible to effectively control the tightening effect of the upper and lower outer walls of the wiring harness cable 4 passing through them, and effectively cooperate with the adjustment of the current top telescopic guide B and the bottom telescopic guide A to achieve the abutment constraint of wiring harness cables 4 with different outer diameters. Specifically, by controlling the horizontal movement of the upper constraint guide unit and the lower constraint guide unit, the length of the wiring harness cable 4 between the constraint points after the two ends are guided and constrained can be quickly controlled. Shortening the distance between the two guide constraint points can better reduce the sagging and vibration amplitude of the wiring harness cable 4 during the guiding movement, thereby improving the accuracy of coding.
