Description

Technical Field

[0001] The invention relates to the technical field of tractor wire harness production, and in particular to a tractor wire harness production and processing device. Background Art

[0002] The wiring harness of the tractor needs to be wrapped with tape during the production process. The tape wrapped on the outside of the wire harness can wrap the exposed wire harness to prevent the wire harness from mechanical wear and improve the wear resistance and aesthetics of the wire harness. At present, the tape wrapping of the tractor's wire harness is generally performed manually. The operator uses a handheld tape wrapping machine to wrap the wire harness with tape. However, the handheld operation mainly relies on manpower and has low efficiency, especially for large-scale production, which requires a lot of manpower.

[0003] In order to solve the above problems, some semi-automatic tape winding machines are now available on the market. The machines can replace part of the manpower to perform tape winding on the wire harness. The machines can automatically wind tape on the outside of the wire harness, but the operator is required to constantly pull the wound wire harness out of the machine at a uniform speed by hand to ensure the uniformity of the tape winding on the outside of the wire harness. Due to the different sizes of the wire harnesses processed in the factory, the speed of pulling the wire harness each time is also different. In the actual operation process, the operator judges the speed and strength of pulling the wire harness based on his own observations, so it is impossible to accurately guarantee the uniformity of the tape winding on the outside of the wire harness. If the speed of pulling the wire harness is too fast, the tape will be too loose, thereby affecting the protective effect of the tape on the wire harness. If the speed is too slow, the tape will be too much wound, which will not only affect the heat dissipation of the wire harness but also waste resources. Therefore, based on the above problems, the present invention provides a tractor wire harness production and processing device to meet the needs. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a tractor wire harness production and processing device by arranging a combing component and a pulling component. The combing component can not only improve the efficiency of the user in placing the wire harness, but also tighten and limit the loose wire harness according to the size of the wire harness during the placement process; the pulling component can not only quickly fix one end of the wire harness, but also automatically pull the wound wire harness out of the device instead of manpower. Such an arrangement ensures that the wire harness will not be unevenly wound with the tape due to too fast or too slow speed during the pulling process. The above arrangement can solve the problem that the speed of the wire harness being pulled by the existing wire harness tape winding equipment during use is difficult to control by manpower, which leads to great operation difficulty and low product quality.

[0008] Optionally, the combing cylinder is a conical structure, and a gradual groove with a V-shaped profile is provided on the top of the combing cylinder, and the size of one end of the conical cylinder close to the body is smaller than the size of the end away from the body.

[0009] Optionally, a weakening groove is provided at the connection position between the expansion piece and the straight tube.

[0010] Optionally, the straight tube, the expansion piece and the adjustment piece are an integrally manufactured structure, an adjustment slot is provided on the adjustment piece, an adjustment knob is inserted into the adjustment slot, and the adjustment knob is connected to the body by a thread.

[0011] Optionally, an arc-shaped structure opening outward is provided at the end of the guide piece, the thickness of the guide piece is smaller than the thickness of the combing cylinder, and a lightweight groove is provided on the guide piece.

[0012] Optionally, a mounting frame is fixedly connected to the bottom of the combing cylinder, and the mounting frame is fixed to the machine body by bolts.

[0013] Optionally, the pulling assembly includes a linear guide rail fixedly connected to the body, a guide rail seat is slidably connected to the linear guide rail, the top of the guide rail seat is fixedly connected to a shell, a frame is fixedly connected to the shell, one end of the frame is fixedly connected to a down-pressing rod, the down-pressing rod is rotatably connected to two connecting rods, one end of the connecting rod is rotatably connected to a sliding rod, the two connecting rods are respectively obliquely arranged on both sides below the down-pressing rod, and the sliding rod and the down-pressing rod are used to squeeze and fix the wiring harness wrapped thereon.

[0014] Optionally, a bending portion is fixedly connected to the other end of the skeleton, and a mounting portion is fixedly connected to one end of the bending portion away from the skeleton. The mounting portion, the bending portion and the skeleton are an integrally manufactured structure, the bending portion is a curved elastic structure, and the mounting portion and the shell are fixed by bolts.

[0015] Optionally, the first locking block and the second locking block are sequentially sleeved on the outer walls of the pressure rod and the sliding rod, and an arc-shaped structure recessed toward the middle is provided at the middle position of the first locking block and the second locking block, and the first locking block and the second locking block are both made of rubber, and an "L"-shaped bending structure is provided at the end of the pressure rod away from the skeleton, and the outer shell is provided with vertical sliding grooves and straight sliding grooves corresponding to the positions of the pressure rod and the sliding rod, respectively.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, by setting a combing component and a pulling component, the combing component and the pulling component are respectively arranged at the wire input end and the wire output end of the machine body. The combing component can not only improve the efficiency of the user in placing the wire harness, but also can tighten and limit the loose wire harness according to the size of the wire harness during the placement process, so that it is more convenient for the device to wrap the wire harness with tape; the pulling component can not only quickly fix one end of the wire harness, but also can automatically pull the wound wire harness out of the device instead of manpower. Compared with manually pulling out the wire harness, such a setting has a more uniform speed and a gentler force in the process of pulling the wire harness, so that the wire harness will not be unevenly wrapped with tape due to excessively fast or slow speed during the pulling process, and the speed of pulling the wire harness can be adjusted according to the size of different wire harnesses in the actual production process, thereby ensuring that the wire harness can be fully wrapped with tape, thereby improving the quality and output of the product.

[0018] By setting a combing cylinder, the overall contour of the combing cylinder is a conical structure and a gradient groove with a "V"-shaped contour is opened on the top. In the process of placing the wire harness, the user can directly place multiple wire harnesses into the combing cylinder from top to bottom along the direction of the conical structure of the combing cylinder and the "V"-shaped groove structure. In the process of placing the wire harness, the conical contour of the combing cylinder combined with the "V"-shaped groove structure can not only squeeze and comb the loose wire harnesses more compactly, but also such a structural setting can improve the efficiency of wire harness placement, and in the process of placing the wire harness, the loose wire harnesses will not be knotted or bent and folded, so that the wire harness is neater before being wrapped with tape, which improves the efficiency of the operator in arranging the wire harness and the quality of the tape wrapped around the wire harness.

[0019] By setting the guide piece, when the user places the wire harness from top to bottom, the wire harness can automatically slide into the combing cylinder with the help of the arc structure of the guide piece. The arc structure can not only prevent the wire harness from being scratched by the corners of the combing cylinder during the placement process, but also can uniformly guide multiple wire harnesses to be stored in the combing cylinder. Such a structural setting, combined with the tapered profile of the combing cylinder and the "V"-shaped groove structure, can further improve the efficiency and neatness of the placement of the wire harness, and effectively improve the efficiency and quality of the tape winding of the wire harness.

[0020] By arranging the straight tube, the expansion piece and the adjustment piece, the straight tube can constrain and limit the wire harnesses of different sizes, ensuring that the wire harnesses are more compact when entering the body, improving the quality and efficiency of the wire harnesses during the tape winding process, and using the expansion piece and the adjustment piece to change the size of the straight tube, not only is the structure simple and clever, but also the actual operation is convenient and labor-saving. In addition, the straight tube, the expansion piece and the adjustment piece are an integrated manufacturing structure. Such an arrangement makes the processing technology of the three simpler during the production process, easier to produce, and reduces the manufacturer's capital investment.

[0021] By setting a pressing rod and a sliding rod, there are two states between the pressing rod and the two sliding rods: before the pressing rod is pressed down, the two sliding rods are located on both sides of the pressing rod, and the relative positions of the three are relatively compact; after the pressing rod is pressed down, the two sliding rods move away from the pressing rod while the pressing rod slides downward, and the relative positions of the three are relatively loose; during actual operation, the user can fix the wiring harness with the help of the above two states, and such fixing method is not only simple in structure and low in cost, but also highly efficient. More importantly, such fixing method will not cause damage to the wiring harness, and the efficiency of wiring harness fixing and disassembly is higher, and it can be applied to wiring harnesses of different sizes.

[0041] like Figures 1 to 10As shown, an embodiment of the present invention provides a tractor wiring harness production and processing device, including a body 1, a wire input end of the body 1 is fixedly connected with a combing component, the combing component is used to assist the user in placing the wiring harness, and the combing component is connected to the body 1; a pulling component is provided at the wire output end of the body 1, the pulling component is used to fix and pull the wiring harness, and the pulling component is connected to the body 1. The wiring harness production and processing device provided by the present application is suitable for the processing flow of tape winding the wiring harness during the production process of the tractor wiring harness. Before tape winding, the wiring harness needs to pass through one end of the body 1 and then be processed by the winding mechanism, and finally, multiple wiring harnesses are bundled into one wiring harness by means of tape winding. In the present application, the working principle of the winding mechanism and the body 1 to tape the wiring harness is disclosed as the prior art, so no further elaboration is made. In the actual product, the winding mechanism is arranged at one end of the body 1 (such as Figure 1 As shown), in the present application, the end close to the winding mechanism is the line inlet end, and the end away from the winding mechanism is the line outlet end.

[0042] By setting a combing component and a pulling component, which are respectively arranged at the wire input end and the wire output end on the body 1, the combing component can not only improve the efficiency of the user in placing the wire harness, but also can tighten and limit the loose wire harness according to the size of the wire harness during the process of placing the wire harness, so that it is more convenient for the device to tape the wire harness; the pulling component can not only quickly fix one end of the wire harness, but also automatically pull the wound wire harness out of the device instead of manpower. Compared with manually pulling out the wire harness, such a setting has a more uniform speed and a gentler force in the process of pulling the wire harness by the pulling component, so that the wire harness will not be unevenly wound with the tape due to excessively fast or slow speed during the pulling process, and the speed of pulling the wire harness can be adjusted according to the size of different wire harnesses in the actual production process, thereby ensuring that the wire harness can be fully wrapped with the tape, thereby improving the quality and output of the product.

[0043] As an implementation method in this embodiment, Figures 1 to 6As shown, the combing assembly includes a combing cylinder 2 fixedly connected to one end of the machine body 1, and a mounting frame 201 is fixedly connected to the bottom of the combing cylinder 2, and the mounting frame 201 is fixed to the machine body 1 by bolts. The combing cylinder 2 is a conical structure, and a gradual groove with a "V"-shaped profile is provided on the top of the combing cylinder 2. The size of the end of the conical cylinder 2 close to the machine body 1 is smaller than the size of the end away from the machine body 1. Guide pieces 4 are symmetrically installed on the top of the combing cylinder 2, and the ends of the guide pieces 4 are provided with arc structures opening outward. The thickness of the guide pieces 4 is smaller than the thickness of the combing cylinder 2, and a lightweight groove is provided on the guide pieces 4. The combing assembly is arranged at the inlet end of the machine body 1, and is mainly composed of a combing cylinder 2 and a straight cylinder 3, wherein the combing cylinder 2 is fixed to the machine body 1 by the mounting frame 201, one end of the mounting frame 201 is fixed to the bottom of the combing cylinder 2, and the other end is fixed to the outer wall of the machine body 1 by bolts. The overall profile of the combing cylinder 2 is a conical structure, close to the machine body 1 The size of one end is smaller than the size of the end away from the body 1, and a gradual groove with a "V"-shaped profile is opened on the top of the combing cylinder 2. The setting of the "V"-shaped groove structure makes the top of the combing cylinder 2 a gradual open profile inclined toward the middle. Through the setting of this structure, the user can directly put multiple wire bundles into the combing cylinder 2 from top to bottom along the direction of the tapered structure of the combing cylinder 2 and the "V"-shaped groove structure during the process of placing the wire bundles. In the process of placing the wire bundles, the tapered profile of the combing cylinder 2 combined with the "V"-shaped groove structure can not only squeeze and comb the loose wire bundles more compactly, but also such a structural setting can improve the efficiency of placing the wire bundles, and in the process of placing the wire bundles, the loose wire bundles will not be knotted or bent and folded, so that the wire bundles are neater before being wrapped with tape, which improves the efficiency of the operator in arranging the wire bundles and the quality of wrapping the wire bundles with tape.

[0044] Furthermore, a guide piece 4 is installed on the top of the combing cylinder 2. The guide piece 4 is installed at the position of the "V"-shaped groove structure on the top of the combing cylinder 2. The thickness of the guide piece 4 is less than the thickness of the combing cylinder 2, and the end of the guide piece 4 is provided with an arc-shaped structure flipped toward the outside. The setting of this structure enables the wire harness to automatically slide into the combing cylinder 2 with the help of the arc-shaped structure of the guide piece 4 during the process of the user placing the wire harness from top to bottom. The setting of the arc-shaped structure can not only prevent the wire harness from being scratched by the corners of the combing cylinder 2 during the placement process, but also can uniformly guide and store multiple wire harnesses into the combing cylinder 2. Such a structural setting, combined with the tapered profile of the combing cylinder 2 and the setting of the "V"-shaped groove structure, can further improve the efficiency and neatness of the placement of the wire harness, and effectively improve the efficiency and quality of the tape winding of the wire harness.

[0045] At present, in the actual production process, before the device wraps the wire harness with tape, the operator needs to manually twist and organize multiple wire harnesses to make the loose wire harnesses relatively compact to facilitate the wrapping of the wire harness with tape. However, due to the large length of the wire harness and the obstruction of the device structure, the step of twisting and arranging the wire harness is relatively laborious to operate manually. In the present application, the setting of the combing component not only effectively solves this problem, but also improves the efficiency of the wire harness placement process and the integrity of the wire harness after placement.

[0046] In this embodiment, if Figures 4 to 6 As shown, the end of the combing cylinder 2 close to the machine body 1 is fixedly connected to the straight cylinder 3, and the two sides of the straight cylinder 3 are fixedly connected to the expansion piece 301, and one end of the expansion piece 301 is fixedly connected to the adjustment piece 302, and a weakening groove 305 is provided at the connection position of the expansion piece 301 and the straight cylinder 3. The straight cylinder 3, the expansion piece 301 and the adjustment piece 302 are an integrated manufacturing structure, and an adjustment groove 303 is provided on the adjustment piece 302, and an adjustment knob 304 is inserted in the adjustment groove 303. The adjustment knob 304 and the machine body 1 are connected by threads, and one end of the straight cylinder 3 is fixed to the combing cylinder 2, and the other end is connected by two sets of expansion pieces. The sheet 301 and the regulating sheet 302 are fixed to the body 1, one end of the expansion sheet 301 is fixed to the straight tube 3, and the rest of the structure is an open structure without constraints. A weakening groove 305 is provided at the connection position between the expansion sheet 301 and the straight tube 3, and the weakening groove 305 thins the connection position between the two. Such a setting makes it easier for the expansion sheet 301 to bend and deform at the position of the weakening groove 305 under the action of external force. The regulating sheet 302 is fixed to the end of the expansion sheet 301 away from the straight tube 3, and the regulating sheet 302 has an outward curvature and conflicts with the outer wall of the body 1 (such as Figures 4 to 6As shown in the figure, the above structure allows the user to change the size of the inner circumferential cross-sectional area of ​​the straight tube 3 by changing the positions of the adjusting piece 302 and the expansion piece 301. Specifically, the adjusting piece 302 is provided with an adjusting slot 303 for fixing the position of the adjusting piece 302. The adjusting knob 304 is inserted into the adjusting slot 303. The adjusting knob 304 is fixed to the body 1 through a threaded connection. When the user needs to change the position of the adjusting piece 302, the user can first loosen the adjusting knob 304 and then slide the adjusting piece 302 to change its position. After the position is determined, the adjusting knob 304 can be tightened again to complete the adjustment operation of the adjusting piece 302. During the process of changing the position of the adjusting piece 302, the expansion piece 301 will be driven to move together. During the displacement of the expansion piece 301, bending deformation will occur from the position where the weakening groove 305 is opened, thereby changing the cross-sectional area of ​​the inner circumference of the straight tube 3. This arrangement allows the straight tube 3 to constrain and limit wire harnesses of different sizes, ensuring that the wire harnesses are more compact when entering the body 1, improving the quality and efficiency of the wire harnesses during tape winding, and using the expansion piece 301 and the adjustment piece 302 to change the size of the straight tube 3, not only is the structure simple and ingenious, but also the actual operation is convenient and labor-saving. In addition, the straight tube 3, the expansion piece 301 and the adjustment piece 302 are an integrated manufacturing structure. This arrangement makes the processing technology of the three simpler during the production process, easier to produce, and reduces the manufacturer's capital investment.

[0047] As an implementation method in this embodiment, Figures 1 to 3 and Figures 7 to 10As shown, the pulling assembly includes a linear guide rail 5 fixedly connected to the body 1, a guide rail seat 501 is slidably connected to the linear guide rail 5, the top of the guide rail seat 501 is fixedly connected to a shell 6, a frame 7 is fixedly connected inside the shell 6, one end of the frame 7 is fixedly connected to a bending portion 701, and the end of the bending portion 701 away from the frame 7 is fixedly connected to a mounting portion 702, the mounting portion 702, the bending portion 701 and the frame 7 are an integral manufacturing structure, the bending portion 701 is a curved elastic structure, the mounting portion 702 and the shell 6 are fixed by bolts, and the linear guide rail 5 in the pulling assembly can drive the guide rail seat 501 to generate linear displacement, and the moving speed of the guide rail seat 501 can be adjusted according to the size of the wire harness. Section, and with the help of system control, in the present application, the working principle of the linear guide 5 and the guide seat 501 is disclosed as the prior art, so it will not be described in detail. In the pulling component, the skeleton 7 is fixed in the shell 6 through the mounting portion 702, and a bending portion 701 is arranged between the mounting portion 702 and the skeleton 7. The bending portion 701 is a "J"-shaped curved elastic structure. Such a structural arrangement makes the overall structure of the skeleton 7 elastic. Under the action of elasticity, the skeleton 7 can be displaced under the pressing action of an external force, and restore the deformation after the external force stops pressing. The mounting portion 702, the bending portion 701 and the skeleton 7 are arranged as an integrated structure. The overall structure of the skeleton 7 is simpler and more ingenious, and is easy to produce and manufacture and install and disassemble.

[0048] In this embodiment, if Figures 7 to 10As shown, the other end of the skeleton 7 is fixedly connected to a push rod 8, and two connecting rods 9 are rotatably connected to the push rod 8. One end of the connecting rod 9 is rotatably connected to a sliding rod 901. The housing 6 is provided with a vertical slide groove 601 and a straight slide groove 602 corresponding to the positions of the push rod 8 and the sliding rod 901, respectively. The outer walls of the push rod 8 and the sliding rod 901 are sequentially sleeved with a first locking block 801 and a second locking block 902. An arc-shaped structure concave toward the middle is provided at the middle position of the first locking block 801 and the second locking block 902. The first locking block 801 and the second locking block 902 are both made of rubber. An "L"-shaped bending structure is provided at one end of the lower pressure rod 8 away from the frame 7. The lower pressure rod 8 is divided into two parts, which are located inside and outside the shell 6 respectively. The lower pressure rod 8 located inside the shell 6 is fixed to the frame 7, and two connecting rods 9 are rotatably connected on the outer wall. The two connecting rods are respectively tilted on both sides of the lower pressure rod 8. One end of the connecting rod 9 is rotatably connected to the lower pressure rod 8, and the other end is rotatably connected to the sliding rod 901. The sliding rod 901 extends outward. The vertical slide groove 601 and the straight slide groove 602 on the outer shell 6 correspond to the positions of the pressing rod 8 and the sliding rod 901 respectively. The vertical slide groove 601 and the straight slide groove 602 can respectively limit the sliding of the pressing rod 8 and the sliding rod 901 in one direction. Under the limiting action of the vertical slide groove 601, the pressing rod 8 can only slide up and down, and under the limiting action of the straight slide groove 602, the sliding rod 901 can only slide left and right. Through the above-mentioned structure, when the user presses the pressing rod 8, the pressing rod 8 slides downward, thereby driving the two sliding rods 901 slides toward the two sides of the pressing rod 8. When the user stops applying force to the pressing rod 8, the pressing rod 8 will be reset to the initial position under the elastic action of the frame 7. The above structure allows two states between the pressing rod 8 and the two sliding rods 901: before the pressing rod 8 is pressed down, the two sliding rods 901 are located on both sides of the pressing rod 8, and the relative positions of the three are relatively compact; after the pressing rod 8 is pressed down, while the pressing rod 8 slides downward, the two sliding rods 901 move away from the pressing rod 8, and the relative positions of the three are relatively loose.During the actual operation process, the user holds one end of the wire harness, then presses down the pressing rod 8 to create a sufficient gap between the pressing rod 8 and the sliding rod 901, and then winds the wire harness around the sliding rod 901 and the pressing rod 8 in a "ji" - shaped trajectory. The winding sequence is as follows: first, the sliding rod 901 on one side of the pressing rod 8, then the pressing rod 8, and finally the sliding rod 901 on the other side of the pressing rod 8. After winding, stop pressing the pressing rod 8 to let it reset. After the pressing rod 8 and the sliding rod 901 reset, their relative positions become compact, and the wound wire harness will also be squeezed together by the three, thereby forming a fixing effect on the wire harness. Fixing the wire harness in this way not only has a simple structure and low cost, but also high efficiency. Importantly, such a fixing method will not damage the wire harness. The efficiency of wire harness fixing and disassembly is higher, and it can be applied to wire harnesses of different sizes. After the wire harness is fixed, the user can start the linear guide 5 to pull the wire harness.;

[0049] Furthermore, a first locking block 801 and a second locking block 902 are sequentially sleeved on the pressing rod 8 and the sliding rod 901 outside the housing 6. The first locking block 801 and the second locking block 902 are the same in terms of the contour of the structure, the installation method, and the material except for the different sizes. Here, the first locking block 801 on the pressing rod 8 will be mainly described, and the second locking block 902 will not be elaborated too much. A convex structure with a conical contour is provided on the inner wall of the first locking block 801, and a concave structure that matches the convex structure is provided on the outer wall of the pressing rod 8. The user can fix and sleeve the first locking block 801 on the pressing rod 8 by means of the convex structure and the concave structure. An inward - concave arc - shaped structure is provided at the middle position of the first locking block 801. The setting of the structure contour, combined with the rubber material of the first locking block 801, enables the wire harness to be guided and limited by its arc - shaped structure when passing through the surface of the first locking block 801. Moreover, the rubber material can not only increase the friction between the wire harness and the first locking block 801, but also make the first locking block 801 soft enough to prevent the wire harness from being pulled and deformed and damaged, thus ensuring the stability and safety of wire harness fixing. The "L" - shaped bending structure at the end of the pressing rod 8 is to facilitate the user to more easily掰动 (it should be "move" in English, for example, "掰动下压杆8" can be "move the pressing rod 8 downwards") the pressing rod 8 to make it move downwards.

[0050] The working principle of the technical solution provided by the present invention is as follows:

[0051] It should be noted that there may be some inaccuracies in the original Chinese text, such as the unclear "掰动" which is translated as "move" in a general sense here. You may need to check and correct the original text for more accurate translation.In use, the user first places the wire harness into the combing cylinder 2 from top to bottom. Since the overall contour of the combing cylinder 2 is a conical structure, and a gradually changing groove body with a "V"-shaped contour is opened at the top of the combing cylinder 2, during the process of placing the wire harness, the conical contour of the combing cylinder 2配合 with the "V"-shaped groove body structure can not only squeeze and comb the loose wire harness to be more compact, but also such a structural setting can improve the efficiency of placing the wire harness, and during the process of placing the wire harness, the loose wire harness will not be knotted or bent and folded, so that the wire harness is neater before tape winding, improving the efficiency of the operator in sorting the wire harness and also improving the quality of the wire harness tape winding; the guiding piece 4 is installed at the position of the "V"-shaped groove body structure at the top of the combing cylinder 2. The thickness of the guiding piece 4 is less than the thickness of the combing cylinder 2, and the end of the guiding piece 4 is provided with an arc-shaped structure that turns outward. The setting of this structure enables the wire harness to automatically slide into the combing cylinder 2 by means of the arc-shaped structure of the guiding piece 4 during the process of the user placing the wire harness from top to bottom. The setting of its arc-shaped structure can not only prevent the wire harness from being scratched by the corners of the combing cylinder 2 during the placement process, but also guide and collect multiple wire harnesses into the combing cylinder 2 uniformly. Such a structural setting can further improve the efficiency and neatness of placing the wire harness, effectively improving the efficiency and quality of the wire harness tape winding. After the wire harness is placed, the user holds one end of the wire harness and then presses down the pressing rod 8 to make the pressing rod 8 slide downward. During the process of the pressing rod 8 sliding downward, it will drive the two sliding rods 901 to slide toward both sides of the pressing rod 8. At this time, their relative positions are relatively loose, and a sufficient gap is generated between the pressing rod 8 and the sliding rods 901. The user winds the wire harness around the sliding rods 901 and the pressing rod 8 in a "ji"-shaped trajectory in sequence. The winding order is: first the sliding rod 901 on one side of the pressing rod 8, then the pressing rod 8, and finally the sliding rod 901 on the other side of the pressing rod 8. After winding, stop pressing the pressing rod 8 to let it automatically reset under the elastic action of the skeleton 7. After the pressing rod 8 and the sliding rods 901 are reset, their relative positions become compact, and the wound wire harness will also be squeezed together by the three, thereby forming a fixing effect on the wire harness. After the wire harness is fixed, the user starts the device to perform tape winding treatment on the wire harness. The wound wire harness is pulled out through the linear guide rail 5. Using the linear guide rail 5 to pull the wire harness instead of human hands has a more uniform speed and a gentler pulling force, so that the wire harness will not have uneven tape winding due to too fast or too slow speed during the pulling process. Moreover, in the actual production process, the speed of pulling the wire harness can be adjusted according to the sizes of different wire harnesses, thereby ensuring that the wire harness can be fully wound with tape, improving the quality and output of the product.
