Description

Technical Field

[0001] The invention belongs to the field of wire harness cutting and processing, in particular to a wire harness positioning device for lightweight wire harness cutting and processing. Background Art

[0002] A wiring harness is an electrical connection component that builds a bridge of communication between two or more isolated electronic circuits, allowing current to flow and realizing the functions of various electronic components. The wiring harness is an indispensable component in various electrical and electronic equipment, and is widely used in automobiles, new energy, industrial equipment, intelligent agricultural machinery and other fields.

[0003] Traditional wire harnesses are made by cutting extra-long wire coils into sections. During the cutting process, the cutting length needs to be predetermined first. After the wire harness is pulled to the predetermined length using a positioning device, the wire harness is cut again, and finally a batch of finished wire harnesses of the same length are obtained.

[0004] However, wire harnesses are often made of flexible materials. The traditional method is generally to use a robotic arm to grab the end of the wire roll, then pull it outward, and cut it after pulling it to the required length. However, when the required length of the wire harness is long, a particularly long robotic arm is required to pull and position it, which not only takes up a large space, but also the center part of the elongated wire harness will bend and sink, requiring the robotic arm to pull it with greater force, which can easily cause the wire harness to break.

[0005] To this end, the present invention provides a wire harness positioning device for lightweight wire harness cutting processing. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a wire harness positioning device for lightweight wire harness cutting processing described in the present invention comprises a positioning box, a front control panel is fixedly connected to the front end of the positioning box, two mutually parallel and vertically arranged limit shafts are arranged at the front end of the front control panel, two mutually parallel and horizontally arranged power shafts are arranged inside the positioning box, a winding shaft capable of horizontal movement is arranged inside the positioning box, a clamping hole for fixing the wire harness is opened on the side of the winding shaft facing the front control panel, and a driving motor 2 for driving the winding shaft to rotate is arranged at one end of the winding shaft;

[0008] Through the setting of the winding shaft, the end of the wire coil is first passed through the two limit shafts and then through the power shaft, and then the end of the wire coil is inserted into the clamping hole of the winding shaft. The clamping hole is provided with a second solenoid valve. The end of the wire coil is clamped by closing the second solenoid valve, and then the winding shaft is translated, thereby pulling the wire harness away from the positioning box for a distance. After stopping, the winding shaft is rotated by the drive motor 2, and the winding shaft is translated along its own length direction during the rotation process, so that the pulled wire harness can be evenly wound on the outside of the winding shaft, and it is ensured that the suspended wire harness is always in the same position. When the amount of wound wire harness is sufficient, the top-down and top-down cutting devices can cut the wire harness, leaving a wire harness of a predetermined length. Through this arrangement, a wire harness with a longer length can be pulled and positioned, and then cut. Since there are fewer wire harnesses in the suspended part, the wire harness can be kept straight without strong pulling, thereby ensuring the quality of the wire harness after cutting. After cutting, the power shaft rotates to move the end of the wire roll back to the position of the power shaft, and then the winding shaft returns to its position, and the end of the wire roll is re-clamped using the clamping hole, and the pulling, positioning and cutting process of the wire harness can be repeated.

[0009] Preferably, a horizontally arranged grabbing table is provided at the rear end of the positioning box, a screw threadedly connected to the winding shaft is provided in the middle of the winding shaft, the screw is arranged in sections, and the two sections of the screw are fixed by magnetic plug-in, and a solenoid valve 1 for fixing the end of the screw is installed in the middle of the grabbing table, and an electric telescopic rod for driving the grabbing table to translate is provided at the upper and lower ends of the grabbing table. When the cut wire harness is wound on the outside of the winding shaft, the screw is located in the grabbing table, and the solenoid valve 1 in the grabbing table fixes the end of the screw, and then the electric telescopic rod extends to drive the grabbing table and part of the screw to separate, and at the same time, the solenoid valve 2 is opened to release the end of the wire harness, so that the wound wire harness can be removed from the end of the winding shaft from the outside of the winding shaft, thereby recovering the processed wire harness.

[0010] Preferably, both ends of the limit shaft are equipped with sliding blocks, the sliding block is slidably engaged with the front control plate, and a compression spring is fixedly connected between the sliding block and the front control plate, and spring telescopic rods are installed between the two ends of the power shaft and the positioning box, and one end of the power shaft is equipped with a driving motor 1 for controlling the rotation of the power shaft. When the wire coil is inserted, the end of the wire coil is first placed between the two limit shafts, and the two limit shafts are squeezed toward the center by the compression spring, and the end of the wire coil is continuously conveyed inward, and the power shaft is driven by the driving motor 1 to rotate, thereby grabbing the end of the wire coil. At the same time, the two horizontally arranged power shafts squeeze the end of the wire coil toward the center under the squeezing of the spring telescopic rod, and cooperate with the limit shaft to ensure that the end of the wire coil is always kept in the center position, and the winding shaft is in the initial position, the clamping hole is opposite to the center position of the wire coil, and with the driving of the power shaft, the end of the wire coil can be inserted into the clamping hole, thereby ensuring the step of fixing the end of the wire coil before processing.

[0011] Preferably, an electric slide rail 1 is fixedly connected to one side of the positioning box, a moving end of the electric slide rail 1 is fixedly connected to a moving seat, the end of the moving seat is fixedly connected to a screw rod, and the screw rod and the winding shaft are controlled to move by the electric slide rail 1, so that the winding shaft is close to the power shaft to grab the end of the wire roll, or close to the grabbing table to reel in the wire harness.

[0012] Preferably, the end of the movable seat is also fixedly connected to a fixed mesh cover, the end of the fixed mesh cover is fixedly connected to a stripping ring, the outer side of the stripping ring is fixedly connected to a plurality of extrusion arms, the end of the extrusion arm is close to the winding shaft, in order to realize fully automated wire harness processing, after the wire harness is cut, as the screw is separated and the winding shaft rotates back, the stripping ring remains stationary, and as the winding shaft returns to its position, the stripping ring will push the wire harness wound on the outer side of the winding shaft off the winding shaft, and when the winding shaft returns to its position, the wire harness will be completely pushed out; since the fixed mesh cover is fixedly connected to the movable seat, the fixed mesh cover is stationary relative to the screw, so the stripping ring will always be at the edge of the wire harness, and thus after the winding shaft returns to its position, the wire harness will be pushed out, thereby completing the fully automatic process of wire harness processing.

The second driving motor can move horizontally along the sliding plate, and the transmission gear is driven by the second driving motor to rotate, and the transmission gear drives the gear ring and the winding shaft to rotate. Since the winding shaft and the screw are threadedly connected, the winding shaft starts to rotate and moves along its own length direction. The movement direction of the winding shaft is controlled by controlling the rotation direction. The second driving motor will slide along the sliding plate and translate with the winding shaft, thereby realizing that the winding shaft rotates and translates the wiring harness while rotating, so that the wiring harness can be neatly wound around its outside.

[0014] Preferably, a clamping block is fixedly connected to the end of the transmission gear, and an annular limiting groove is opened at the end of the winding shaft, and the clamping block is slidably clamped in the limiting groove.

Through this arrangement, only the driving motor 2 needs to be started to complete the two functions of rotation and advancement of the winding shaft, reducing the operation steps and difficulty.

[0015] Preferably, the sliding plate is fixedly connected to a fixed mesh cover, and the fixed mesh cover is sleeved on the outside of the winding shaft. By fixing the sliding plate and the fixed mesh cover together, the sliding plate can be always located below the second driving motor and move in translation following the second driving motor.

[0016] Preferably, the rear end of the positioning box is fixedly connected with a rear sealing plate, and the middle part of the positioning box is fixedly connected with a limiting rail, and the limiting rail is used to assist in fixing the screw, and the surface of the rear sealing plate is provided with a through hole for passing the fixed mesh cover, and the rear sealing plate reduces the influence of the external environment on the winding shaft and other parts, and the limiting rail is for receiving and guiding the screw close to the power shaft.

After the wire harness is straightened and positioned, it may also need surface marking, stripping and other processing. The entire positioning box can be controlled to move horizontally through the electric slide rail 2, so as to be moved to another processing equipment. The lifting seat is used to control the lifting and lowering of the positioning box, and also assists in moving the wire harness to the position where processing is required.

When the amount of wound wire harness is sufficient, the top-down and top-down cutting devices can cut the wire harness, leaving a predetermined length of wire harness. Through this setting, a longer wire harness can be pulled and positioned, and then cut. Since there are fewer wire harnesses in the suspended part, the wire harness can be straightened without strong pulling, thereby ensuring the quality of the wire harness after cutting.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figures 1 to 7 As shown, a wire harness positioning device for lightweight wire harness cutting processing described in an embodiment of the present invention comprises a positioning box 1, a front control panel 2 is fixedly connected to the front end of the positioning box 1, two mutually parallel and vertically arranged limit shafts 13 are arranged at the front end of the front control panel 2, two mutually parallel and horizontally arranged power shafts 9 are arranged inside the positioning box 1, a winding shaft 11 capable of horizontal movement is arranged inside the positioning box 1, a clamping hole 20 for fixing the wire harness is opened on the side of the winding shaft 11 facing the front control panel 2, and a driving motor 16 for driving the winding shaft 11 to rotate is arranged at one end of the winding shaft 11;

[0032] Through the setting of the winding shaft 11, the end of the wire coil is first passed through the two limit shafts 13, and then through the power shaft 9, and then the end of the wire coil is inserted into the clamping hole 20 of the winding shaft 11. The clamping hole 20 is provided with a solenoid valve 2. The end of the wire coil is clamped by closing the solenoid valve 2, and then the winding shaft 11 is translated, thereby pulling the wire harness away from the positioning box 1 for a distance. After stopping, the winding shaft 11 is driven by the driving motor 2 16 to rotate. At the same time, during the rotation process, the winding shaft 11 is translated along its own length direction, so that the pulled wire harness can be evenly wound on the outside of the winding shaft 11, and it is ensured that the suspended wire harness is always in the same position. When the amount of wound wire harness is sufficient, the cutting from top to bottom and from top to bottom is performed. The equipment can cut the wire harness, leaving a wire harness of a predetermined length. Through this arrangement, a wire harness of a longer length can be pulled and positioned, and then cut. Since there are fewer wire harnesses in the suspended part, the wire harness can be kept straight without strong pulling, thereby ensuring the quality of the wire harness after cutting. After cutting, the power shaft 9 rotates to move the end of the wire roll back to the position of the power shaft 9, and then the winding shaft 11 returns to its position, and the end of the wire roll is re-clamped using the clamping hole 20, and the pulling, positioning and cutting process of the wire harness can be repeated. A roller counter is provided at one end of the power shaft 9 for recording the number of turns passing through the power shaft 9, thereby calculating the length of the wire harness passing through the power shaft 9, and ensuring that the length of the cut wire harness is the predetermined length.

[0033] A horizontally arranged grabbing platform 7 is arranged at the rear end of the positioning box 1, a screw 22 threadedly connected to the winding shaft 11 is arranged in the middle of the winding shaft 11, the screw 22 is arranged in sections, the two sections of the screw 22 are fixed by magnetic plug-in, and the two sections of the screw 22 are splined, so that the two sections of the screw 22 cannot slide relative to each other, so the two sections of the screw 22 will not separate from each other during the rotation process, and a solenoid valve 1 for fixing the end of the screw 22 is installed in the middle of the grabbing platform 7, and the upper and lower ends of the grabbing platform 7 are provided with electric telescopic rods 6 for driving the grabbing platform 7 to translate;

[0034] During operation, after the cut wire harness is wound on the outside of the winding shaft 11, the screw 22 is located in the grabbing table 7. The solenoid valve 1 in the grabbing table 7 fixes the end of the screw 22. Then the electric telescopic rod 6 extends, driving the grabbing table 7 and part of the screw 22 to separate. At the same time, the solenoid valve 2 opens to release the end of the wire harness. In this way, the wound wire harness can be removed from the end of the winding shaft 11 from the outside of the winding shaft 11, thereby recovering the processed wire harness. It should be noted that the threaded connection between the screw 22 and the winding shaft 11 is located at the end away from the grabbing table 7. When the two sections of the screw 22 are separated, the connection between the screw 22 and the winding shaft 11 is still guaranteed. When the wire harness is removed, the separated screw 22 is docked again.

[0035] Slide blocks are installed at both ends of the limit shaft 13, and the slide blocks are slidably engaged with the front control panel 2, and a compression spring is fixedly connected between the slide block and the front control panel 2. Spring telescopic rods 14 are installed between both ends of the power shaft 9 and the positioning box 1, and a driving motor 12 for controlling the rotation of the power shaft 9 is installed at one end of the power shaft 9;

[0036] During operation, when putting in the wire coil, first put the end of the wire coil between the two limit shafts 13, the two limit shafts 13 are squeezed toward the center by the compression spring, and continue to transport the end of the wire coil inward, and drive the power shaft 9 to rotate by the driving motor 12, so as to grasp the end of the wire coil, and at the same time, the two horizontally arranged power shafts 9 squeeze the end of the wire coil toward the center under the pressure of the spring telescopic rod 14, and cooperate with the limit shaft 13 to ensure that the end of the wire coil is always kept in the center position, and the winding shaft 11 is in the initial position, and the clamping hole 20 is opposite to the center position of the wire coil, and with the driving of the power shaft 9, it can be ensured that the end of the wire coil is inserted into the clamping hole 20, which ensures the step of fixing the end of the wire coil before processing.

[0037] An electric slide rail 3 is fixedly connected to one side of the positioning box 1, a moving end of the electric slide rail 3 is fixedly connected to a moving seat 15, and an end of the moving seat 15 is fixedly connected to a screw rod 22;

[0038] During operation, the electric slide rail 3 controls the screw rod 22 and the winding shaft 11 to move, so that the winding shaft 11 is close to the power shaft 9 to grab the end of the wire coil, or close to the grabbing platform 7 to reel in the wire harness.

[0039] The end of the movable seat 15 is also fixedly connected to a fixed mesh cover 10, the end of the fixed mesh cover 10 is fixedly connected to a stripping ring 18, the outer side of the stripping ring 18 is fixedly connected to a plurality of extrusion arms 19, and the end of the extrusion arm 19 is close to the winding shaft 11;

[0040] During operation, in order to realize fully automated wire harness processing, after the wire harness is cut, as the screw 22 separates and the winding shaft 11 rotates back, the stripping ring 18 remains stationary. As the winding shaft 11 returns to its original position, the stripping ring 18 will push the wire harness wound on the outside of the winding shaft 11 off the winding shaft 11. When the winding shaft 11 returns to its original position, the wire harness will be completely pushed out. Since the fixed mesh cover 10 is fixedly connected to the movable seat 15, the fixed mesh cover 10 is stationary relative to the screw 22. Therefore, the stripping ring 18 will always be at the edge of the wire harness, and thus after the winding shaft 11 returns to its original position, the wire harness will be pushed out, thereby completing the fully automatic process of wire harness processing.

[0041] The output end of the second drive motor 16 is fixedly connected with a transmission gear 24, the end of the winding shaft 11 is fixedly connected with a gear ring 25 meshing with the transmission gear 24, a sliding plate 23 is arranged below the second drive motor 16, the bottom of the second drive motor 16 is slidably engaged with the sliding plate 23, and the second drive motor 16 can move horizontally along the sliding plate 23;

[0042] During operation, the transmission gear 24 is driven to rotate by the driving motor 2 16, and the transmission gear 24 drives the gear ring 25 and the winding shaft 11 to rotate. Since the winding shaft 11 and the screw 22 are threadedly connected, the winding shaft 11 starts to rotate and moves along its own length direction. The movement direction of the winding shaft 11 is controlled by controlling the rotation direction. The driving motor 2 16 will slide along the sliding plate 23 and translate with the winding shaft 11, thereby realizing that the winding shaft 11 rotates and translates while winding the wire harness, so that the wire harness can be neatly wound on its outside.

[0043] A clamping block is fixedly connected to the end of the transmission gear 24, and an annular limiting groove 26 is formed at the end of the winding shaft 11, and the clamping block is slidably clamped in the limiting groove 26;

[0044] During operation, since the end of the transmission gear 24 is restricted in the annular limiting groove 26, and the bottom of the driving motor 2 16 is clamped on the sliding plate 23, the transmission gear 24 and the gear ring 25 will always be in a meshing state, and when the transmission gear 24 drives the gear ring 25 and the winding shaft 11 to rotate and move, since the clamping block is restricted in the winding shaft 11, it will also carry the transmission gear 24 and the driving motor 2 16 to translate together. Through this arrangement, only the driving motor 2 16 needs to be started to complete the two functions of rotation and advancement of the winding shaft 11, reducing the operating steps and difficulty.

[0045] The sliding plate 23 is fixedly connected to the fixed mesh cover 10, and the fixed mesh cover 10 is sleeved on the outer side of the winding shaft 11;

[0046] During operation, the sliding plate 23 and the fixed mesh cover 10 are fixed together, so that the sliding plate 23 is always located below the second driving motor 16 and moves in translation following the second driving motor 16 .

[0047] The rear end of the positioning box 1 is fixedly connected with a rear sealing plate 8, the middle of the positioning box 1 is fixedly connected with a limit rail, the limit rail is used to assist in fixing the screw 22, and the surface of the rear sealing plate 8 is provided with a through hole for passing the fixed mesh cover 10;

[0048] When working, the rear sealing plate 8 reduces the influence of the external environment on the winding shaft 11 and other parts when not working, and the limit rail is for receiving and guiding the screw 22 close to the power shaft 9.

[0049] The bottom mounting portion of the positioning box 1 is provided with a lifting seat 5 for controlling the lifting of the positioning box 1, and the bottom of the lifting seat 5 is provided with an electric slide rail 2 4 for driving the lifting seat 5 to move horizontally;

[0050] During operation, after the wire harness is straightened and positioned, it may need to be surface marked, stripped, and other processes. The entire positioning box 1 can be controlled to move horizontally through the electric slide rail 4, so as to be moved to another processing equipment. The lifting seat 5 is used to control the lifting and lowering of the positioning box 1, and also to assist in moving the wire harness to the position where processing is required.

[0051] During operation, through the setting of the winding shaft 11, the end of the wire coil is first allowed to pass through the two limit shafts 13, and then through the power shaft 9, and then the end of the wire coil is inserted into the clamping hole 20 of the winding shaft 11, and the clamping hole 20 is provided with a solenoid valve 2. The end of the wire coil is clamped by closing the solenoid valve 2, and then the winding shaft 11 is translated, so as to pull the wire harness away from the positioning box 1 for a distance. After stopping, the winding shaft 11 is driven by the driving motor 2 16 to rotate, and the winding shaft 11 is translated along its own length direction during the rotation process, so that the pulled wire harness can be evenly wound on the outside of the winding shaft 11, and the suspended wire harness can be ensured. The harness is always in the same position. When the amount of wound harness is sufficient, the top-down and top-down cutting devices can cut the harness, leaving a harness of a predetermined length. Through this arrangement, a harness with a longer length can be pulled and positioned, and then cut. Since there are fewer harnesses in the suspended part, the harness can be straightened without strong pulling, thereby ensuring the quality of the harness after cutting. After the cutting is completed, the power shaft 9 rotates to move the end of the wire roll back to the position of the power shaft 9, and then the winding shaft 11 returns to its position, and the end of the wire roll is re-clamped using the clamping hole 20, and the pulling, positioning and cutting process of the harness can be repeated.

[0052] After the cut wire harness is wound on the outside of the winding shaft 11, the screw 22 is located in the grabbing table 7. The first solenoid valve in the grabbing table 7 fixes the end of the screw 22. Then the electric telescopic rod 6 extends to drive the grabbing table 7 and part of the screw 22 to separate. At the same time, the second solenoid valve opens to release the end of the wire harness. In this way, the wound wire harness can be removed from the end of the winding shaft 11 from the outside of the winding shaft 11, thereby recovering the processed wire harness.

[0053] When putting in the wire coil, first put the end of the wire coil between the two limit shafts 13. The two limit shafts 13 are squeezed toward the center by the compression spring, and the end of the wire coil continues to be transported inward. The power shaft 9 is driven to rotate by the driving motor 12, so that the end of the wire coil is caught. At the same time, the two horizontally arranged power shafts 9 squeeze the end of the wire coil toward the center under the pressure of the spring telescopic rod 14. With the limit shaft 13, it can be ensured that the end of the wire coil is always kept in the center position. When the winding shaft 11 is in the initial position, the clamping hole 20 is directly opposite to the center position of the wire coil. With the driving of the power shaft 9, it can be ensured that the end of the wire coil is inserted into the clamping hole 20, which ensures the step of fixing the end of the wire coil before processing.

[0054] The electric slide rail 3 controls the screw rod 22 and the winding shaft 11 to move, so that the winding shaft 11 is close to the power shaft 9 to grab the end of the wire coil, or close to the grabbing table 7 to reel the wire harness;

[0055] In order to realize fully automated wire harness processing, after the wire harness is cut, as the screw 22 separates and the winding shaft 11 rotates back, the stripping ring 18 remains stationary. As the winding shaft 11 returns to its original position, the stripping ring 18 will push the wire harness wound on the outside of the winding shaft 11 off the winding shaft 11. When the winding shaft 11 returns to its original position, the wire harness will be completely pushed out. Since the fixed mesh cover 10 is fixedly connected to the movable seat 15, the fixed mesh cover 10 is stationary relative to the screw 22. Therefore, the stripping ring 18 will always be at the edge of the wire harness, so that after the winding shaft 11 returns to its original position, the wire harness will be pushed out, thereby completing the fully automated process of wire harness processing.

[0056] The transmission gear 24 is driven to rotate by the driving motor 2 16, and the transmission gear 24 drives the gear ring 25 and the winding shaft 11 to rotate. Since the winding shaft 11 and the screw rod 22 are threadedly connected, the winding shaft 11 starts to rotate and moves along its own length direction. The moving direction of the winding shaft 11 is controlled by controlling the rotation direction. The driving motor 2 16 slides along the sliding plate 23 and moves along with the winding shaft 11, thereby realizing that the winding shaft 11 rotates and winds the wire harness while moving horizontally, so that the wire harness can be neatly wound on its outside;

[0057] Since the end of the transmission gear 24 is restricted in the annular restriction groove 26, and the bottom of the driving motor 2 16 is clamped on the sliding plate 23, the transmission gear 24 and the gear ring 25 will always be in a meshing state, and when the transmission gear 24 drives the gear ring 25 and the winding shaft 11 to rotate and move, since the clamping block is restricted in the winding shaft 11, it will also carry the transmission gear 24 and the driving motor 2 16 to translate together. Through this arrangement, only the driving motor 2 16 needs to be started to complete the two functions of rotating and advancing the winding shaft 11, reducing the operation steps and difficulty;

[0058] By fixing the sliding plate 23 and the fixed mesh cover 10 together, the sliding plate 23 can be always located below the second driving motor 16 and move in translation with the second driving motor 16;

[0059] The rear sealing plate 8 reduces the influence of the external environment on the winding shaft 11 and other parts when not working, and the limit rail is for receiving and guiding the screw 22 close to the power shaft 9;

[0060] After the wire harness is straightened and positioned, it may need to be surface marked, stripped, and other processes. The electric slide rail 4 can control the entire positioning box 1 to move horizontally, so that it can be moved to another processing equipment. The lifting seat 5 is used to control the lifting of the positioning box 1, and also to assist in moving the wire harness to the position where processing is required.

[0061] The above shows and describes the basic principles, main features and advantages of the present invention.
