Description

Technical Field

[0001] This invention relates to the field of wire harness processing technology, and more specifically to a wire harness double-end synchronous wiring hot pressing device. Background Technology

[0002] In the wire harness manufacturing process, some wire harnesses use terminals to connect two wire harnesses at their two ends to achieve specific functions, such as automotive internal control signal transmission wire harnesses. In the manufacturing process of this type of wire harness, the terminals at both ends and the conductor cores need to be heat-pressed together to ensure the stability and conductivity of the connection.

[0003] Typically, after the wire harness is connected at both ends, insulating sleeves and waterproof sleeves are applied to the connection points. Conventional wire harness hot pressing often involves hot pressing one end of the wire harness first, then removing the other end and re-fixing it for hot pressing. This clamping and positioning is done in two separate steps, resulting in cumbersome clamping operations and low processing efficiency. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a wire harness double-end synchronous wiring hot pressing device to solve the problem that the double-end hot pressing is carried out separately, resulting in cumbersome clamping operation and low processing efficiency.

[0010] As a further embodiment of the present invention, one end of the mounting frame is provided with a plurality of clamping components for clamping wire harnesses; the clamping components include: a lifting frame slidably mounted on one side of the mounting frame, the bottom of the lifting frame being provided with a first upper clamping claw cylinder and a second upper clamping claw cylinder; and a first electric push rod fixedly mounted on the top of the mounting frame, the movable end of the first electric push rod passing through the mounting frame and fixed to the lifting frame.

Detailed Implementation

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Reference Figures 1-11 This invention provides a wire harness double-end synchronous hot pressing device, which solves the problem of cumbersome clamping operations and low processing efficiency caused by separate double-end hot pressing. It mainly consists of a heat shrink station 3, an upper sleeve adjustment station 4, a synchronous hot pressing station 5, a material unloading station 6, a positioning module 8, and a material loading module 9, as detailed below: A mounting bracket 2 and a linear motor 7 (a Kollmorgen DDL series linear motor can be selected) are fixedly installed on the frame 1. Multiple movers can be set on the track of the linear motor 7. A feeding module 9 is installed on each mover. The feeding module 9 will clamp and position the wire harness and realize the switching of work positions under the drive of the linear motor 7. On the mounting frame 2, from left to right, there are heat shrink station 3, upper sleeve adjustment station 4, synchronous heat pressing station 5, and material unloading station 6. Among them, heat shrink station 3 is used to simultaneously heat shrink the heat shrink tube 12 at both ends of the wire harness; upper sleeve adjustment station 4 is used to transfer the two waterproof sleeves 13 sleeved on the middle line 10 to the outside of the heat shrink tube 12; synchronous heat pressing station 5 is used to simultaneously heat press the two ends of the waterproof sleeve 13 with the wire harness; and unloading station 6 is used to unload the wire harness after heat pressing. In addition to the heat shrink station 3 and the synchronous hot pressing station 5, a positioning module 8 is also set up to adjust the position of the sleeve fitted on the wire harness.

[0032] Specifically, such as Figure 4 As shown, the specific structure of the feeding module 9 is as follows: A mounting base 901 is fixedly installed on the mover of the linear motor 7. A slide block 903 is slidably installed on the top of the mounting base 901. A fourth electric push rod 902 is fixedly installed on one side of the mounting base 901. The movable end of the fourth electric push rod 902 passes through the mounting base 901 and is fixed to the slide block 903. The slide block 903 is moved on the mounting base 901 by the extension and retraction of the fourth electric push rod 902. A first lower gripper cylinder 904 is fixedly installed above the slide 903, and the first lower gripper cylinder 904 clamps both ends of the intermediate line 10; a U-shaped frame 906 is fixedly installed on one side of the mounting base 901, and a second lower gripper cylinder 905 is fixedly installed at the bottom of the U-shaped frame 906, and the second lower gripper cylinder 905 clamps the end line 11. The connection terminal between the intermediate line 10 and the end line 11 is located between the first lower gripper cylinder 904 and the second lower gripper cylinder 905. The clamping positions of the first lower gripper cylinder 904 and the second lower gripper cylinder 905 can be adjusted by moving the fourth electric push rod 902. Specifically, the adjustment is as follows: When the terminal is biased towards the first lower gripper cylinder 904, the first lower gripper cylinder 904 clamps the wire harness. The fourth electric push rod 902 pushes the slide 903 to move the first lower gripper cylinder 904 closer to the second lower gripper cylinder 905, so that the terminal is adjusted to the center position of the processing station. Conversely, it pulls the slide 903 to move in the opposite direction, so as to adapt to wire harnesses of different lengths and specifications, ensure that the terminal is always in the predetermined processing position, and avoid position deviation during processing affecting the accuracy of heat shrinking and heat pressing.

[0033] Furthermore, such as Figure 9 As shown, in order to allow the two feeding modules 9 to dock during workstation changes, a clamping assembly is also provided. The clamping assembly is mounted on the mounting frame 2, and its specific structure is as follows: A lifting frame 202 is slidably installed on one side of the mounting frame 2. A first upper gripper cylinder 203 and a second upper gripper cylinder 204 are provided at the bottom of the lifting frame 202. A chuck 907 is fixedly installed at the gripper of the first upper gripper cylinder 203, the second upper gripper cylinder 204, the first lower gripper cylinder 904, and the second lower gripper cylinder 905. The first upper gripper cylinder 203 and the second lower gripper cylinder 905 are used in conjunction, and the second upper gripper cylinder 204 and the first lower gripper cylinder 904 are used in conjunction. At the same time, a first electric push rod 201 is fixedly installed on the top of the mounting frame 2, and the movable end of the first electric push rod 201 passes through the mounting frame 2 and is fixed to the lifting frame 202; When the wire harness on the loading module 9 needs to be switched at a different workstation, the first electric push rod 201 pushes the lifting frame 202 down, and the first upper gripper cylinder 203 and the second upper gripper cylinder 204 extend their grippers to cooperate with the corresponding lower gripper cylinder below (when clamping the wire harness, the upper gripper cylinder and the lower gripper cylinder are misaligned to clamp), together clamping the corresponding position of the wire harness. Then the original loading module 9 carrying the wire harness releases its grippers, leaves the current workstation, and goes to the loading area to receive the next set of wire harnesses to be processed. The next empty loading module 9 moves to the lower part of the workstation and aligns. The lifting frame 202 moves down to allow the new loading module 9 to clamp the wire harness. The first upper gripper cylinder 203 and the second upper gripper cylinder 204 then release their grippers and are lifted back to their original positions by the lifting frame 202, completing the wire harness transfer between the two loading modules 9. This avoids wire harness misalignment during workstation switching and ensures the accuracy of the processing position at each workstation.

[0034] The first upper gripper cylinder 203, the second upper gripper cylinder 204, the first lower gripper cylinder 904, and the second lower gripper cylinder 905 are all flip-type gripper cylinders, which can avoid the wire harness after clamping it; the inner side of the clamping head 907 for clamping the wire harness is provided with an arc-shaped groove that matches the outer contour of the wire harness.

[0035] In addition, the first upper gripper cylinder 203 and the second upper gripper cylinder 204 in the clamping assembly located above the heat shrink station 3 and the synchronous heat pressing station 5 are both fixed on the lifting frame 202. The first upper gripper cylinder 203 in the clamping assembly located on the upper adjustment station 4 is fixed on the lifting frame 202, and the second upper gripper cylinder 204 is fixed on the movable seat 401 that slides on the lifting frame 202. A lead screw 402 is rotatably installed at the bottom of the lifting frame 202 in the upper adjustment station 4. The lead screw 402 works in conjunction with the movable seat 401. At the same time, a first reduction motor 404 is fixedly installed on one side of the lifting frame 202. The first reduction motor 404 is fixedly connected to the lead screw 402. The first reduction motor 404 drives the lead screw 402 to rotate, causing the moving seat 401 to slide at the bottom of the lifting frame 202, thereby adjusting the distance between the second upper gripper cylinder 204 and the first upper gripper cylinder 203. A connecting clamp 403 is fixedly installed on one side of the second upper gripper cylinder 204 in the upper adjustment station 4. The end of the connecting clamp 403 is provided with a slot 814. The inlet end of the slot 814 is a bevel 815. The bevel 815 facilitates the entry of the wire harness into the slot 814. When the first electric push rod 201 extends, it will drive the lifting frame 202 to move downward, thereby driving the first upper gripper cylinder 203 and the second upper gripper cylinder 204 to move downward synchronously. At this time, the connecting clamp 403 will contact the wire harness, causing the wire harness to enter the slot 814 and be located on one side of the waterproof sleeve 13 (i.e., the rear end of the waterproof sleeve 13). Subsequently, the second upper jaw cylinder 204 clamps the waterproof sleeve 13, causing the waterproof sleeve 13 to deform slightly. In this state, the waterproof sleeve 13 can be moved by the second upper jaw cylinder 204. If the waterproof sleeve 13 is displaced between the second upper jaw cylinder 204, it can also be moved by the connecting clamp 403 to ensure that the waterproof sleeve 13 is fitted on the outside of the heat-shrinkable tube 12 after heat shrinking, so as to avoid the waterproof sleeve 13 being not properly adjusted and affecting the accuracy of subsequent synchronous hot pressing.

[0036] Once both waterproof sleeves 13 are in place, the first upper gripper cylinder 203 and the second upper gripper cylinder 204 are released, and the lifting frame 202 drives the entire clamping assembly to rise and reset. Then, in conjunction with the linear motor 7, the feeding module 9 can be driven to transfer the wire harness to the next synchronous hot pressing station 5 for processing.

[0037] In order to heat shrink the heat shrink tubing 12, a hot air blower 301 (which can be composed of a miniature fan and a heating wire, and the hot air temperature can be adjusted by controlling the heating power of the heating wire to meet the heat shrinking requirements of heat shrink tubing 12 of different materials) is set in the heat shrinking station 3. The hot air blower 301 is installed at the predetermined position of the wiring terminal in the heat shrinking station 3, and the air outlet of the hot air blower 301 is aligned with the placement position of the heat shrink tubing 12. After the feeding module 9 drives the wire harness into the heat shrinking station 3 for positioning, the hot air blower 301 is started, which can blow hot air to heat the heat shrink tubing 12 at both ends of the wire harness, so that the heat shrink tubing 12 is heated and shrinks to cover the outside of the wiring terminal, completing the double-end synchronous heat shrinking operation. After the heat shrinking is completed, the hot air blower 301 stops working and waits for the wire harness to be transferred to the next station.

[0038] Before the heat shrinking process begins, the positioning module 8 will be used to adjust the position of the heat shrink tube 12 to ensure that the heat shrink tube 12 is located outside the wiring terminal.

[0039] Reference Figures 5-8 The specific structure of positioning module 8 is as follows: A movable frame 802 is slidably mounted on the frame 1. A third electric push rod 801 is fixedly installed on one side of the movable frame 802, and the cylinder of the third electric push rod 801 is fixed to the frame 1. The movable frame 802 is moved on the frame 1 by the extension and retraction of the third electric push rod 801. A fixed seat 803 is fixedly installed above the movable frame 802. A sliding groove 805 is opened on the top of the fixed seat 803. A slide 804 is slidably installed in the sliding groove 805. The two slides 804 are driven to move towards each other by the first synchronous moving component set above the fixed seat 803. Meanwhile, a guide groove 812 is opened on one side of the slide 804, and a clamp 813 is slidably installed in the guide groove 812. The end of the clamp 813 is the same as the end of the connecting clamp 403. The two clamps 813 are driven to move towards each other by the second synchronous moving component set on one side of the slide 804. When it is necessary to align the positions of the heat shrink tubing 12 or the waterproof sleeve 13, the third electric push rod 801 first extends to drive the moving frame 802 to move towards the terminal block, so that the clamps 813 on both sides are located on opposite sides of the two terminal blocks. Then the first synchronous moving component drives the two slides 804 to move towards the wire harness, so that the wire harness enters the slot 814. Subsequently, the second synchronous moving component drives the two clamps 813 to move towards each other along the guide groove 812. The clamps 813 position the heat shrink tubing 12 or the waterproof sleeve 13. If the position of the tubing is offset, the clamps 813 will push the tubing to the preset alignment position during the process of moving towards each other.

[0040] Once the position adjustment is complete, the first synchronous moving component and the second synchronous moving component drive in opposite directions, causing the two clamps 813 to reset. The third electric push rod 801 also drives the entire positioning module 8 to retract and avoid interference with subsequent heat shrinking processing.

[0041] The first synchronous moving component and the second synchronous moving component can adopt the same structure, or they can be adjusted according to actual needs.

[0042] The specific structure of the first synchronous movement component is as follows: A second reduction motor 808 is fixed at the bottom of the fixed base 803. The output shaft of the second reduction motor 808 passes through the fixed base 803 and a first gear 807 is fixedly installed thereon. A first rack 806 is fixedly installed on one side of the slide 804 and meshes with the first gear 807. The second reduction motor 808 drives the first gear 807 to rotate, which in turn drives the two meshing first racks 806 to move synchronously in opposite directions. This, in turn, drives the two slides 804 to move towards or away from each other in the slide groove 805, so as to realize the synchronous opening and closing of the two slides 804, accurately control the movement distance, and adapt to the positioning requirements of different specifications of tubing (heat shrink tubing 12 or waterproof sleeve 13).

[0043] The second synchronous moving assembly has the same structure as the first synchronous moving assembly. A third reduction motor 809 is fixedly installed on one side of the slide 804. A second gear 810 is fixedly installed on the output shaft of the third reduction motor 809. A second rack 811 is fixedly installed on one side of the clamp 813. The second gear 810 and the second rack 811 mesh. The second gear 810 is driven to rotate by the third reduction motor 809, which can drive the two clamps 813 to move synchronously towards or away from each other, thus completing the pushing and positioning operation of the sleeve (heat shrink tubing 12 or waterproof sleeve 13).

[0044] It should be noted that the first reduction motor 404, the second reduction motor 808, and the third reduction motor 809 are all speed-regulating motors with encoders and worm gear reducers, which can precisely control the rotation angle of the output shaft, thereby precisely controlling the movement distance of the corresponding components, adapting to the position adjustment requirements when processing wire harnesses of different specifications, and ensuring that the positioning accuracy meets the processing requirements.

[0045] Reference Figure 11 The specific structure of synchronous hot pressing station 5 is as follows: A lower support frame 501 is slidably installed on the frame 1. A lower heating block 504 is provided on the top of the lower support frame 501. A second electric push rod 502 is fixedly installed on the frame 1. The movable end of the second electric push rod 502 is fixed to the lower support frame 501. The lower support frame 501 is raised and lowered by the extension and retraction of the second electric push rod 502, thereby changing the height of the lower heating block 504. Meanwhile, a heating block 503 is installed at the bottom of the lifting frame 202 in the clamping assembly located above the synchronous hot pressing station 5. The upper heating block 503 and the lower heating block 504 work together. The lifting frame 202 is driven to move downward by the first electric push rod 201, so that the upper heating block 503 and the lower heating block 504 come closer to each other and compress and heat the waterproof sleeve 13 that is sleeved on the outside of the heat shrink tube 12. The end of the waterproof sleeve 13 is heated and shrinks and is tightly pressed together with the wire harness. The synchronous hot pressing station 5 can perform hot pressing operations on the waterproof sleeves 13 at both ends of the wire harness at the same time, and complete the double-end hot pressing processing in one go, avoiding the repeated clamping errors caused by processing twice and improving the processing accuracy.

[0046] After hot pressing is completed, the first electric push rod 201 drives the lifting frame 202 to rise, and the second electric push rod 502 drives the lower support frame 501 to fall. The upper heating block 503 and the lower heating block 504 move away from each other, and the processed wire harness can be transferred to the unloading station 6 by the loading module 9.

[0047] It should be noted that both the upper heating block 503 and the lower heating block 504 have built-in heating rods, and the preset temperature can be set according to the processing requirements of the waterproof sleeve 13 to keep the hot pressing temperature constant and avoid temperature fluctuations affecting the hot pressing processing quality. At the same time, the bottom of the upper heating block 503 and the top of the lower heating block 504 are provided with arc-shaped pressure grooves that match the contour of the end of the waterproof sleeve 13, so that pressure can be applied evenly during hot pressing, ensuring that the hot pressing part is heated and pressed evenly, and improving the sealing processing quality.

[0048] At the unloading station 6, the same transfer operation as at the upper sleeve adjustment station 4 and heat shrink station 3 is repeated. The clamping component clamps and lifts the processed wire harness, and the unloading mechanism can then remove the processed wire harness to complete the unloading. The empty loading module 9 returns to the loading area and the processing is repeated.

[0049] The unloading mechanism is driven by a ball screw module, and the rest of the structure is the same as the clamping components on the upper adjustment station 4 and the heat shrink station 3, thereby realizing automated unloading operation without manual unloading, which further improves the automation level of the wire harness waterproof sleeve 13 heat shrink and hot pressing processing equipment.

[0050] It should be noted that the first electric push rod 201, the second electric push rod 502, the third electric push rod 801, and the fourth electric push rod 902 are all linear motion power actuators that convert electrical energy into mechanical energy. They can be connected to an external power supply and control switch, and drive the push rod to perform linear reciprocating motion by controlling the forward and reverse rotation of the motor. By cooperating with limit switches or Hall sensors, the safety protection and position control of the push rod's extension and retraction stroke can be realized. Those skilled in the art can set them according to actual needs.

[0051] The following is the specific operating principle of this device: First, the wire harness is placed in the loading area by an automated loading device. The first empty loading module 9 clamps the middle wire 10 and the end wire 11 respectively. According to the initial position of the terminal block, the fourth electric push rod 902 pushes the slide block 903 to move, and adjusts the position of the first lower gripper cylinder 904 so that the terminal block moves to the predetermined center position of the processing station. Then, the loading module 9 moves with the wire harness under the drive of the linear motor 7.

[0052] Before the heat shrink tube 12 is heat-shrinked after the wire harness enters the heat shrink station 3, the positioning module 8 first positions and adjusts the heat shrink tube 12: the third electric push rod 801 pushes the moving frame 802 to move towards the terminal block, the first synchronous moving component drives the two slides 804 to move towards each other, so that the wire harness enters the slot 814 of the clamp 813, and then the second synchronous moving component drives the two clamps 813 to move towards each other, pushing the offset heat shrink tube 12 to the preset alignment position. After the adjustment is completed, the positioning module 8 retracts as a whole to avoid the misalignment. Then the hot air blower 301 starts blowing hot air, so that the heat shrink tube 12 is heated and shrinks to cover the outside of the terminal block, completing the double-end synchronous heat shrinking.

[0053] After heat shrinking is completed, the feeding module 9 transports the wire harness to the upper sleeve adjustment station 4. At this time, the outer side of the heat shrink tube 12 has been pre-covered with a waterproof sleeve 13. During the downward movement of the clamping component, the connecting clamp 403 first restricts the waterproof sleeve 13 into position. Then, the second upper jaw cylinder 204 clamps the waterproof sleeve 13. The first reduction motor 404 drives the lead screw 402 to rotate, adjusting the position of the second upper jaw cylinder 204 and pushing the waterproof sleeve 13 to the predetermined position outside the heat shrink tube 12. After ensuring that both waterproof sleeves 13 are adjusted into position, the clamping component rises and resets, and the feeding module 9 transfers the wire harness to the synchronous hot pressing station 5.

[0054] After entering the synchronous hot pressing station 5, the first electric push rod 201 drives the lifting frame 202 to move down, and the second electric push rod 502 drives the lower support frame 501 to rise, so that the upper heating block 503 and the lower heating block 504 close the mold, and simultaneously extrude and heat the waterproof sleeves 13 on both sides, so that the waterproof sleeves 13 shrink due to heat and are tightly pressed with the wire harness, completing the double-end hot pressing process in one go. After the hot pressing is completed, the upper and lower heating blocks separate, and the feeding module 9 transports the processed wire harness to the unloading station 6, where the unloading mechanism automatically takes it out to complete the unloading. The empty feeding module 9 returns to the feeding area to start the next round of processing.

[0055] The entire processing is automated, including position adjustment, heat shrinking, positioning, hot pressing, and unloading. No manual adjustments or repeated clamping are required. It can be adapted to wire harnesses of different lengths and specifications, effectively ensuring processing accuracy and improving processing efficiency.
