Description

Technical Field

[0001] This utility model relates to the field of electronic wire harness inkjet printing technology, and in particular to an inkjet printing fixture for electronic wire harnesses. Background Technology

[0002] Electronic wire harness inkjet printing refers to the process of printing clear and identifiable marking information on the insulation surface of each wire in an electronic wire harness (an assembly consisting of multiple wires bundled and connected according to specific requirements, widely used in automobiles, home appliances, electronic equipment, etc.) using professional inkjet printing equipment (such as OMA-JET G8300T).

[0003] Electronic wire harness coding fixtures refer to the devices and tools used to fix and support wires and ensure coding quality during the wire coding process.

[0004] Currently, when marking electronic wire harnesses, a support frame and multiple sets of guide wheels are needed to support, guide, and straighten the wire harnesses to be marked. This ensures that the wire harnesses pass smoothly and taut through the marking equipment, preventing overlapping or uneven marking. Furthermore, before marking, the insulation layer of the wire harnesses needs to be cleaned to remove residual oil, dust (such as release agents or workshop dust from the production process) that could hinder ink adhesion. After passing through multiple guide rollers, the wire harnesses also require precise guidance using guide tubes to ensure they move along a fixed path during marking, resulting in accurate and consistent marking positions and preventing wire harness misalignment that could lead to incorrect or unclear markings.

[0005] In existing technologies, when cleaning the insulation layer of electronic wire harnesses, alcohol is sprayed onto the outer surface of the insulation layer using a spraying device. However, in traditional methods, not all the alcohol sprayed can be applied to the outer surface of the insulation layer, resulting in alcohol waste. Furthermore, the existing conduit and support frame are welded to each other. When a small electronic wire harness passes through the conduit, a gap remains between the insulation layer and the inner wall of the conduit. This prevents the conduit from accurately guiding the wire harness, causing it to move along a fixed path during the coding process. This results in inaccurate and consistent coding positions, preventing wire harness misalignment that could lead to incorrect or unclear coding. Utility Model Content

[0006] To overcome the above deficiencies, this utility model provides a coding fixture for electronic wire harnesses, aiming to improve the problems in the prior art.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1-5 One embodiment of this utility model provides: a coding fixture for electronic wire harnesses, comprising: The workbench 1 has a support platform 3 fixedly installed on its top. At least two support plates 20 are fixedly installed on the top of the support platform 3. The central axes of the two support plates 20 on adjacent sides coincide with each other.

[0023] A lower pressure plate 4 is slidably installed on the top of the support plate 20. The top of each of the two lower pressure plates 4 is rotatably sleeved with a drive threaded rod. The bottom of the drive threaded rod is rotatably connected to the top of the support platform 3. Rotating the drive threaded rod can realize the up and down movement of the lower pressure plate 4, thereby adjusting the distance between the lower pressure plate 4 and the support platform 3, and limiting the movement of the lower pressure plate 4 with the cooperation of the drive threaded rod.

[0024] Guide rollers 22 for guiding the electronic wire harness are rotatably mounted on one side of both the lower pressure plate 4 and the support plate 20. Before the electronic wire harness is marked, the free end of the electronic wire harness is first passed through the cleaning component. After the free end of the electronic wire harness passes through the cleaning component, it passes through one of the lower pressure plates 4 and the support platform 3 on one side, ensuring that the outer surface of the insulation layer of the electronic wire harness is in contact with the outer surface of the multiple guide rollers 22 mounted on one side of the support platform 3 and the lower pressure plate 4. The multiple guide rollers 22 can limit the movement trajectory of the electronic wire harness, preventing the electronic wire harness from deviating significantly during movement. Under the pressure of the multiple guide rollers 22, the bent outer surface of the electronic wire harness can be flattened, thus preparing for the subsequent marking operation.

[0025] By adjusting the height between the lower pressure plate 4 and the support platform 3, the distance between the guide roller 22 installed on one side of the lower pressure plate 4 and the guide roller 22 installed on the side of the support platform 3 is adjusted, so that electronic wire harnesses of different diameters can pass between the guide roller 22 installed on one side of the lower pressure plate 4 and the guide roller 22 installed on the side of the support platform 3, and ensure that the outer surface of the insulation layer of the moving electronic wire harness is in contact with the outer surface of the multiple guide rollers 22.

[0026] The conduit 9 is detachably installed on one side of one of the support plates 20. After the electronic wire harness passes between the guide roller 22 installed on one side of the lower pressure plate 4 and the guide roller 22 installed on one side of the support platform 3, the free end of the conduit 9 passes through the conduit 9.

[0027] A vertical plate is fixedly installed on the top of the support platform 3. Multiple support rollers are rotatably installed on one side of the vertical plate, and a drive plate 7 is fixedly installed on the top of the vertical plate. A drive wheel 8 for driving the electronic wire harness is fixedly installed on one side of the drive plate 7, and a drive motor for rotating the drive wheel 8 is fixedly installed on the other side of the drive plate 7. When the electronic wire harness passes through the inside of the conduit 9, the electronic wire harness passes between the support rollers and the drive wheel 8. At the same time, the outer wall of the electronic wire harness is in close contact with the drive wheel 8 and its outer wall. Under the action of the drive motor, the drive wheel 8 rotates along its own axis, thereby applying power to the electronic wire harness under the action of friction, so that the electronic wire harness can move stably along its own axis.

[0028] A coding device 6 (model OMA-JETG8300T) for marking electronic wire harnesses is fixedly installed on the top of workbench 1. This device features high printing speed and efficiency, and can meet the high-requirement, high-intensity, and long-term printing production needs while ensuring the clarity of the printed information. Its advanced functions and tools can minimize planned and unexpected downtime, helping to improve production efficiency and product quality.

[0029] The inkjet printer 6 has a fixed support base on its inkjet end. The outer wall of the support base is detachably equipped with a heating machine 2 for heating the insulation layer of the electronic wire harness. The inkjet printer 6 mainly consists of an inkjet printer body and an inkjet tube. The ink inlet end of the inkjet tube is connected to the ink outlet end of the inkjet printer body through a hose. At the same time, the inkjet tube is perpendicular to the top of the support platform 3, and the inkjet end of the inkjet tube points to the top of the support platform 3. After the electronic wire harness is removed from the inside of the conduit 9, the insulation layer of the electronic wire harness can be inkjet printed through the inkjet tube.

[0030] After the coding operation is completed, the air around the insulation layer can be heated by the heating machine 2 (heating temperature is 45℃-50℃), so that the ink attached to the outer surface of the electronic wire harness dries quickly and prevents the ink from falling off the outer surface of the electronic wire harness.

[0031] The workbench 1 has a lifting platform 5 slidably mounted on its top. One side of the lifting platform 5 is fixedly connected to the outer wall of the inkjet tube. The top of the lifting platform is rotatably mounted with a drive threaded rod. The bottom of the drive threaded rod is rotatably connected to the top of the workbench 1. By rotating the drive threaded rod, the straight distance between the inkjet end of the inkjet tube and the insulating wire harness can be adjusted to prevent the inkjet end from colliding with the surface of the wire and scratching the insulation layer, or ink accumulation that causes the characters to be too thick. By adjusting the height, it can be ensured that the inkjet distance (the vertical distance between the inkjet end and the surface of the wire harness) of different wire diameters is always in the "optimal range" (usually 2-5mm), ensuring the clarity and consistency of the characters (this is existing technology and will not be elaborated on here).

[0032] The straight-line distance between the inner wall of the conduit 9 and the outer surface of the insulation layer of the electronic wire bundle is no more than 0.5 mm, so as to avoid the electronic wire bundle from deviating after passing through the conduit 9 and to ensure that the electronic wire bundle can always maintain a straight-line movement.

[0033] Mounting block 24 is slidably mounted on the top of support platform 3. One end of guide tube 9 is fixedly sleeved with fixing plate 10. Mounting block 24 has a mounting groove on one side that communicates with its top. Fixing plate 10 is detachably mounted in the inner cavity of mounting groove. One end of fixing plate 10 has a mounting hole. Fixing screw 11 is detachably mounted in the inner cavity of mounting hole. The bottom of inner cavity of mounting groove has a fixing thread groove that matches fixing screw 11. When fixing plate 10 is inserted from the top of mounting block 24 and contacts the bottom of inner cavity of mounting groove, the middle of the opening end of mounting hole and the middle of the opening end of thread groove are on the same horizontal line. Then, the small end of fixing screw 11 passes through mounting hole and enters inner cavity of thread groove. Then, the large end of fixing screw 11 is continuously rotated until the large end of fixing screw 11 is in contact with the top of fixing plate 10, thus fixing fixing plate 10 in inner cavity of mounting groove.

[0034] When the fixing plate 10 is fixed in the inner cavity of the mounting groove, the middle part of the opening end of the conduit 9 coincides with the central axis of the free end of the electronic wire bundle, so that the electronic wire bundle can be smoothly inserted into the inner cavity of the conduit 9 while maintaining linear movement.

[0035] When it is necessary to perform inkjet printing on electronic wire harnesses of different diameters, a conduit 9 that matches the diameter of the electronic wire harness must be selected. Therefore, the conduit 9 needs to be replaced. When replacing the conduit 9, first use a tool to continuously rotate the large end of the fixing screw 11 until the small end of the fixing screw 11 is completely removed from the inside of the threaded groove. Then, the fixing plate 10 installed inside the mounting groove can be removed from the mounting groove. Then, the conduit 9 that matches the diameter of the electronic wire harness is connected to the mounting block 24 through the cooperation of the fixing plate 10 and the fixing screw 11.

[0036] The inner cavity of the mounting slot is symmetrically provided with receiving slots 23 that are adapted to the fixing plate 10. The mounting slot and the receiving slot 23 are adjacent to each other and a through slot 12 for wire harness movement is provided. The width and height of the receiving slot 23 are both greater than the diameter of the largest diameter conduit 9, so that electronic wire harnesses of different diameters can pass smoothly through the through slot 12 and enter the interior of the conduit 9.

[0037] Multiple lifting blocks 15 are fixedly installed on one side of the mounting block 24. One of the lifting blocks 15 has a drive threaded hole at its top that is connected to its bottom. A lifting threaded rod 14 is installed in the inner cavity of the drive threaded hole through a threaded engagement. Since the diameter of the electronic wire harness to be printed is different, the central axis of the free end of the electronic wire harness is offset from the central axis of the opening end of the conduit 9 before entering the interior of the conduit 9. Therefore, it is necessary to fine-tune the installation position of the conduit 9. When fine-tuning the position of the conduit 9, the lifting threaded rod 14 is continuously rotated, so that the mounting block 24 moves up or down along the axis of the lifting threaded rod 14. Thus, the height of the mounting block 24 is fine-tuned so that the opening end of the conduit 9 of different diameters can be flush with the middle of the free end of the electronic wire harness, and the electronic wire harness can always move along the central axis of the electronic wire harness, avoiding the electronic wire harness offset from causing the printing position to be incorrect or unclear.

[0038] The top of each of the remaining lifting blocks 15 is provided with a guide hole. A limiting rod 13 for limiting the movement trajectory of the mounting block 24 is slidably installed in the inner cavity of the multiple guide holes. Through the cooperation of multiple limiting rods 13 and multiple guide holes, the movement trajectory of the mounting block 24 can be limited, preventing the mounting block 24 from rotating when the lifting threaded rod 14 rotates, so that the mounting block 24 can always move along the axial direction of the lifting threaded rod 14.

[0039] The fixing plate 10, fixing screw 11, lifting threaded rod 14 and limiting rod 13 constitute the lifting component. The lifting component allows for the replacement of guide tubes 9 with different inner diameters. At the same time, the distance between the guide tube 9 and the top of the support platform 3 can be finely adjusted according to the diameter of the electronic wire harness, so that the opening end of the guide tube 9 with different diameters can be flush with the middle of the free end of the electronic wire harness, and the electronic wire harness can always move along the central axis of the electronic wire harness, avoiding the electronic wire harness from shifting and causing the inkjet printing position to be incorrect or unclear.

[0040] The cleaning tube 16 is detachably installed on the top of the support platform 3, and a cleaning sponge 18 is fixedly sleeved in the inner cavity of the cleaning tube 16. The cleaning tube 16 has a storage chamber for storing cleaning fluid. The inner wall of the storage chamber has wetting holes 19 arranged in a ring and communicating with the inner cavity of the cleaning tube 16. The cleaning fluid stored in the storage chamber can be immersed into the cleaning sponge 18 through multiple wetting holes 19, so that the cleaning sponge 18 can be quickly wetted.

[0041] Before the free end of the electronic wire harness is inserted between the guide roller 22 installed on one side of the lower pressure plate 4 and the guide roller 22 installed on one side of the support platform 3, the free end of the electronic wire harness is first inserted into the inner cavity of the cleaning sponge 18 and tightly adhered to the inner wall of the cleaning sponge 18. As the electronic wire harness continues to move, the cleaning sponge 18 can evenly apply the cleaning liquid to the outer surface of the electronic wire harness, thereby trapping the oil and dust adhering to the insulation layer on the inner wall of the cleaning sponge 18, avoiding obstruction when the ink adheres to the insulation layer, and preventing the cleaning liquid from splashing when applied to the insulation layer, thus preventing waste of the cleaning liquid.

[0042] Collection plates 17 for collecting cleaning fluid are fixedly installed at both ends of the cleaning tube 16. The collection plates 17 are bent, and the central axis of the collection plates 17 coincides with the central axis of the cleaning tube 16. When the electron beam moves continuously in the inner cavity of the cleaning sponge 18, the moving electron beam will squeeze the cleaning sponge 18. After the cleaning sponge 18 is squeezed, the cleaning fluid immersed in the cleaning sponge 18 is squeezed out. The squeezed cleaning fluid then flows into the top of the collection plate 17. Thus, the squeezed cleaning fluid is collected and reused under the action of the collection plate 17, avoiding waste of the cleaning fluid.

[0043] The top of the cleaning tube 16 is fixedly equipped with a replenishment tube 21 for replenishing the cleaning fluid. The inner cavity of the replenishment tube 21 is connected to the inner cavity of the storage chamber. The storage chamber can be filled with cleaning fluid in a timely manner through the replenishment tube 21, so that the cleaning sponge 18 is always kept wet by the cleaning fluid.

[0044] The cleaning sponge 18, cleaning tube 16, and collection plate 17 constitute the cleaning component. The cleaning component can evenly apply the cleaning fluid to the outer surface of the electronic wire harness and quickly remove the dust and oil adhering to the insulation layer, avoiding obstruction when the ink adheres to the insulation layer. At the same time, it can prevent the cleaning fluid from splashing when applied to the insulation layer, thus preventing waste of the cleaning fluid.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
