[0037] See Figure 1 and Figure 2 An automatic coding tube device for wire harnesses includes a support assembly 1 and a wire feeding assembly 2. The support assembly 1 is provided with a rotating assembly 7 and wire feeding assemblies 4 and heat shrinking mechanisms 5 respectively arranged on both sides of the rotating assembly 7. Clamping assemblies 6 and cutting assemblies 9 are respectively arranged at the front and rear ends of the rotating assembly 7. A coding assembly 3 is arranged above the wire feeding assembly 4. A cooling pipe 8 is installed on the support base 11.

[0038] Support component 1 forms the main body of the equipment, providing installation positions and support foundations for each component. The internal layout of these components enables efficient collaborative operation, ensuring convenient insertion and removal of the coding tube. The wire feeding component 2 delivers the coding tube into support component 1, ensuring an orderly supply. The coding component 3 performs laser coding on the coding tube. The wire feeding component 4 positions and delivers the coding tube, ensuring its position does not shift during coding. The heat-shrinking mechanism 5 heats the wire harness already inserted into the coding tube, causing the coding tube to shrink and wrap tightly around the wire harness after heating. The clamping component 6 clamps and positions the wire harness inserted into the rotating component 7, preventing the coding tube from falling off due to movement or vibration after insertion. The rotating component 7 serves as the core channel, guiding the wire harness to connect with the coding tube and rotating to insert the coding tube, achieving continuous and efficient operation. The cooling pipe 8 cools the heat-shrinked coding tube, quickly shaping it and enhancing its fit with the wire harness, ensuring a secure connection. The cutting component 9 cuts the encoding tube. After the encoding tube is fed into the rotating component 7, the cutting component 9 cuts it precisely according to the preset length to ensure that each segment of the encoding tube meets the specifications.

[0039] See Figure 3 The support assembly 1 includes a support base 11, a workbench 12 is mounted on the support base 11, a support plate 13 is provided in the middle of the support base 11, a guide groove 14 is provided on the support plate 13, a protective cover 15 is provided above the support base 11, and a control module 16 is installed on the side wall of the protective cover 15.

[0040] The support base 11 provides an installation position for the workbench 12 and the support plate 13 and supports the entire main structure of the equipment. The workbench 12 places the wire harness and facilitates the operator to feed the wire harness into the rotating component 7. The support plate 13 forms a support structure inside, which is convenient for installation. The guide groove 14 provides rotation conditions for the wire feeding component 4, so that the wire feeding component 4 can rotate on the support plate 13. The protective cover 15 protects the components on the support plate 13, forming a semi-enclosed structure, which effectively prevents external dust and interference factors from affecting the operation of the equipment, and at the same time facilitates maintenance and repair. The control module 16 monitors the entire device. The control module 16 collects the equipment operation data in real time and feeds it back to the control system to realize the coordination of the actions and parameter optimization of each execution component, ensuring seamless connection of processes such as sleeve, coding, heating, and cooling. The control module 16 is connected to the host computer, where the initial parameters are preset.

[0041] See Figure 4 and Figure 5 The wire feeding assembly 2 is installed inside the support assembly 1. The wire feeding assembly 2 includes a wire feeding mounting block 21, a connecting plate 22 is mounted on the wire feeding mounting block 21, a feeding shaft 23 is provided on the connecting plate 22, and a first wire feeding wheel 24 and a second wire feeding wheel 25 are rotatably sleeved on the feeding shaft 23. The wire feeding mounting block 21 is a support structure for the wire feeding assembly 2. It is used to fix the connecting plate 22 and ensure its stable installation in the support assembly 1. The connecting plate 22 supports the first wire feeding wheel 24 and the second wire feeding wheel 25 through cooperation with the feeding shaft 23. The first wire feeding wheel 24 and the second wire feeding wheel 25 respectively feed two coding tubes. The first wire feeding wheel 24 and the second wire feeding wheel 25 can rotate on the feeding shaft 23 and supply two coding tubes at the same time.

[0042] The marking component 3 includes a positioning plate 31, which is mounted on the support base 11. A laser marking device 32 is mounted on the positioning plate 31, and the position of the laser marking device 32 is adapted to the position of the wire feeding component 4.

[0043] The positioning plate 31 provides positioning for the laser marking device 32. The positioning plate 31 is fixed on the support base 11. The laser marking device 32 is installed on the positioning plate 31 and performs marking operations on the coding tube. Through the installation position of the positioning plate 31, the laser marking head of the laser marking device 32 can be accurately aligned with the designated area of ​​the coding tube, ensuring that the marking position is consistent and clearly identifiable. The laser marking device 32 adjusts the marking parameters through the control module 16, and automatically matches the laser power and pulse frequency according to the material and wire diameter of the coding tube.

[0044] See Figure 4 , Figure 5 , Figure 6 , Figure 8 and Figure 12 The wire feeding assembly 4 includes a wire pressing component 41, a reversing component 42, and a conveying component 43. The wire pressing component 41 includes a wire pressing table 411, a wire pressing groove 412 is provided on the wire pressing table 411, and multiple sets of wire pressing plates 413 are also installed on the wire pressing table 411.

[0045] The crimping component 41 limits the two fed coding tubes, restricting their feeding positions. The position of the crimping component 41 is adapted to the position of the laser marking device 32, ensuring that the laser marking device 32 marks the two coding tubes on the crimping component 41. The two coding tubes are fed in by the first feeding wheel 24 and the second feeding wheel 25, respectively. The crimping table 411 provides a position for the crimping groove 412. The size of the crimping groove 412 is adapted to the size of the two coding tubes, guiding the position of the coding tubes and ensuring that the coding tubes remain stably aligned during the conveying process. The crimping plate 413 limits the vertical position of the two coding tubes in the crimping groove 412 to prevent jumping or deviation. The reversing component 42 turns the coding tubes after marking, changing the two coding tubes from a horizontal state to a vertical state. The conveying component 43 conveys the turned coding tubes and sends them into the rotating component 7. The cutting component 9 cuts the coding tubes.

[0046] The commutation component 42 includes a commutation plate 421, on which two wire feed grooves 422 are symmetrically arranged.

[0047] The reversing plate 421 provides a setting position for the wire feeding groove 422. The two vertically set wire feeding grooves 422 convey the two encoder tubes vertically and send them into the conveying component 43.

[0048] The conveying component 43 includes a conveying motor 431, which is mounted below the support base 11. The output end of the conveying motor 431 is connected to a drive shaft 432 in a guide groove 14. A drive roller 433 is mounted on the drive shaft 432. A conveying plate 434 is provided on one side of the drive roller 433. A connecting shaft 435 is mounted on the conveying plate 434, and a driven roller 436 is rotatably mounted on the connecting shaft 435. The conveyor motor 431 is fixed on the support base 11. The output end of the conveyor motor 431 rotates to drive the transmission shaft 432 to rotate, which in turn drives the active roller 433 to rotate synchronously. The conveyor plate 434 is fixed on the support base 11. The driven roller 436 can rotate on the connecting shaft 435. When the two coding tubes enter between the active roller 433 and the driven roller 436 in a vertical state, the active roller 433 and the driven roller 436 squeeze the coding tubes. While the active roller 433 rotates to drive the coding tubes to be conveyed, it also drives the driven roller 436 to rotate. The synchronous rotation of the squeeze forms a traction force. The vertical conveying facilitates the continuous and stable transmission of the active roller 433 and the driven roller 436, avoids slippage or jamming, and ensures that the coding tubes maintain a uniform speed during the vertical conveying process. The vertically conveyed coding tubes are sent to the rotating assembly 7. The cutting assembly 9 cuts the coding tubes to a fixed length. The vertical state facilitates precise control of the cutting.

[0049] See Figure 10 The heat shrinking mechanism 5 includes a heating component 51, which includes a first mounting platform 511. A first driving cylinder 512 is mounted on the first mounting platform 511, and a heating plate 513 is provided on the first driving cylinder 512. The length of the heating plate 513 is adapted to the position of the insertion slot 75.

[0050] Heating component 51 heats the encoder tube in rotating assembly 7. The encoder tube is heated in rotating assembly 7 and adheres to the insulation of the wire harness to achieve heat shrinking and shaping. First mounting platform 511 provides mounting position for first drive cylinder 512. First drive cylinder 512 drives heating plate 513 to move horizontally. Heating plate 513 on first drive cylinder 512 heats encoder tube. Heating plate 513 is a heating wire. After being energized, it can dissipate heat to make encoder tube shrink evenly and tightly wrap the wire harness. When first drive cylinder 512 drives heating plate 513 to move, the purpose of heat shrinking encoder tubes of different lengths is achieved. By adjusting the extension and retraction of first drive cylinder 512, the heat shrinking requirements of wire harnesses of different specifications can be adapted.

[0051] The heat shrinking mechanism 5 also includes a supporting component 52, which includes a second mounting platform 521. The second mounting platform 521 is disposed on the side of the first mounting platform 511. A second driving cylinder 522 is mounted on the second mounting platform 521. An extension plate 523 is mounted on the output end of the second driving cylinder 522. A supporting platform 524 is disposed on the extension plate 523. A supporting plate 525 is mounted on the supporting platform 524.

[0052] The holding component 52 restricts the position of the wire harness extending into the rotating assembly 7 to prevent the wire harness from being inserted too deeply, which would cause the mounting position of the encoder tube to deviate from the preset path. The first mounting platform 511 provides an installation position for the first drive cylinder 512. The output end of the second drive cylinder 522 drives the extension plate 523 to move horizontally, adjusting the depth of the wire harness inserted into the rotating assembly 7. The holding platform 524 provides a setting position for the holding plate 525. The holding plate 525 abuts against the end of the wire harness. By adjusting the position of the holding plate 525 on the holding platform 524, the length of the wire harness end in the rotating assembly 7 is controlled.

[0053] The clamping assembly 6 includes a clamping mounting block 61. A wire inlet cylinder 62 is mounted on the side wall of the clamping mounting block 61. A clamping cylinder 63 is mounted on the output end of the wire inlet cylinder 62. A clamping groove 66 is provided on the output end of the wire inlet cylinder 62. A pressure plate 64 is mounted on the output end of the clamping cylinder 63. The pressure plate 64 is slidably disposed in the clamping groove 66. A wire passage groove 65 is provided on the output end of the wire inlet cylinder 62.

[0054] The clamping mounting block 61 is fixed on the support base 11, providing an installation position for the inlet cylinder 62. The inlet cylinder 62 has a clamping groove 66 above the two wire passage grooves 65. The pressure plate 64 is L-shaped, and the size of the clamping groove 66 is adapted to the size of the pressure plate 64. When the output end of the clamping cylinder 63 retracts, it drives the pressure plate 64 to descend. When the wire harness is inserted into the rotating assembly 7, the output end of the inlet cylinder 62 moves and moves closer to each other, so that the two wire passage grooves 65 restrict the position of the wire harness. After the inlet cylinder 62 finishes moving, the pressure plate 64 descends to press and fix the wire harness, ensuring that the wire harness is in a pressed state for coding tube sleeve and heat shrinking, and the two wire passage grooves 65 can guide the insertion position of the wire harness.

[0055] See Figure 5The rotating assembly 7 includes a first fixed plate 71 and a second fixed plate 72. A rotating motor 73 is installed between the first fixed plate 71 and the second fixed plate 72. The output end of the rotating motor 73 passes through the second fixed plate 72 and is mounted on a threading turntable 74. The threading turntable 74 is provided with multiple sets of insertion slots 75. The position of the cooling pipe 8 corresponds to the position of the threading turntable 74. The first fixed plate 71 and the second fixed plate 72 fix the rotating motor 73. The rotation of the output end of the rotating motor 73 drives the threading turntable 74 to rotate. After the wire harness passes through two insertion slots 75, it abuts against the supporting plate 525. At the same time, after passing through the two insertion slots 75, the encoding tube is assembled. After abutting in place, the output end of the wire inlet cylinder 62 actuates, moving closer together, limiting... The axial position of the wire harness in the wire guide groove 65 is determined. The clamping cylinder 63 drives the pressure plate 64 to descend and press the wire harness. The output end of the first drive cylinder 512 extends to heat the encoder tube, causing it to shrink and adhere to the surface of the wire harness. After heating, the first drive cylinder 512 retracts, and the output end of the clamping cylinder 63 drives the pressure plate 64 to rise and release the wire harness. The output end of the wire inlet cylinder 62 actuates, causing the wire guide groove 65 to separate and no longer restrict the axial position of the wire harness. The wire threading turntable 74 rotates and adjusts to the processing position of the next set of insertion slots 75 to continue inserting the wire harness. The wire harness at the heat-shrinked position rotates to the position of the cooling pipe 8. The cooling pipe 8 blows cold air onto the heat-shrinked wire harness to accelerate the cooling and shaping of the encoder tube, ensuring uniform and tight shrinkage and preventing springback deformation.

[0056] See Figure 11 The cutting assembly 9 includes a cutting positioning seat 91, a cutting cylinder 92 is mounted on the cutting positioning seat 91, and a cutting blade 93 is mounted on the output end of the cutting cylinder 92.

[0057] The cutting positioning seat 91 is fixed on the support seat 11 and is set between the conveying component 43 and the insertion slot 75. After the coding tube is conveyed, the output end of the cutting cylinder 92 extends and drives the cutting blade 93 to cut the coding tube.

[0058] When the driving roller 433 and driven roller 436 of the conveying component 43 continuously convey the two coded tubes in a vertical state downwards and reach the preset length, the conveying motor 431 stops. At this time, the threading turntable 74, driven by the rotating motor 73, has rotated its set of empty insertion slots 75 and stopped at the receiving station directly opposite the discharge port of the conveying component 43. This station is located at the position of the cutting blade 93 of the cutting component 9. The end of the conveying plate 434 or the cutting positioning seat 91 is provided with a guide funnel or centering gripper (not shown in the figure, but for this purpose). (A conventional alignment structure easily implemented by those skilled in the art); When the lower end of the encoder tube approaches the entrance of the insertion slot 75, the guide structure fine-tunes the encoder tube so that its axis coincides with the axis of the target insertion slot 75. Subsequently, the cutting cylinder 92 actuates, driving the cutting blade 93 to simultaneously cut the two encoder tubes at a preset length. The two cut, predetermined length encoder tubes, under their own weight and possibly with the assistance of air blowing or small push rods, fall smoothly into the two corresponding insertion slots 75 directly below, and are initially positioned and held by the inner wall of the insertion slot 75. After the encoder tube insertion is completed, the rotating motor 73 starts again, driving the threading turntable 74 to rotate at a certain angle. Depending on the number of insertion slots, the insertion slot 75 that just contained the encoder tube is rotated to the next wire bundle insertion and heat shrinking station, while a new set of empty insertion slots 75 is rotated to the receiving station to receive the next round of fed and cut encoder tubes, thus realizing a cyclic operation.

[0059] The output end of the rotating motor 73 passes through the second fixed plate 72 and is then installed on the threading turntable 74. The threading turntable 74 is equipped with multiple sets of insertion slots 75.
