Description

Technical Field

[0001] The invention belongs to the technical field of wire harness assembly, and in particular relates to a wire harness assembly device for an electric control system. Background Art

[0002] The wiring harness is used to carry signals and power connections between devices. The wiring harness assembly is the sum of strings of wires and cables that transmit information. In order to facilitate the connection of the wires, an assembly device is required to connect the wiring harness and the terminal blocks together. For example, an automatic pulling wiring harness assembly device is proposed in patent publication number CN217507884U.

[0003] When assembling the wire harness, it is necessary to pre-process the wire harness first, mainly by stripping off a certain length of the insulating outer sheath to expose the metal wire of the appropriate length (usually determined by the specifications and requirements of the terminal), then insert the stripped wire into the crimping part of the terminal, and finally, use the crimping tool to align the crimping part of the terminal for crimping. However, when the wire harness is automatically stripped, if the position of the wire harness is not accurate enough, the problem of inaccurate stripping length of the wire harness will occur. If the stripping length of the wire harness is too long, the excessively long bare wire will accidentally contact other surrounding lines or metal parts, thereby causing a short circuit; and if the stripping length of the wire harness is too short, it may not meet the connection requirements. For example, when using crimping terminals, stripping too short will cause the wire to be unable to be fully inserted into the crimping part of the terminal, resulting in an unstable connection.

When the wire harness needs to be stripped, the induction box 191 and the sliding block 192 can remain relatively fixed.

[0041] The operating principle of the present invention is now described as follows: the wiring terminal 7 is placed at a set position on the support table 301 by an external loading device, and the wiring harness is placed in the automatic clamp 82 (the external loading device can be a robot or other device). After the external loading device places the wiring harness in the automatic clamp 82, the PLC controller 3 controls the angle motor 6 to drive the turntable 5 to rotate. For example, when the number of the clamping components 8 is four, the PLC controller 3 controls the turntable 5 to rotate ninety degrees at a time by controlling the angle motor 6, so that the wiring harness clamped inside the automatic clamp 82 is aligned with the wiring part of the wiring terminal 7;

[0042] During the rotation of the turntable 5, the PLC controller 3 controls the first electric push rod 52 to work, and the first electric push rod 52 controls the support frame 101 to move outward to the set position, and then the PLC controller 3 controls the lifting electric push rod 102 to work, and the lifting electric push rod 102 drives the sensing component 19 and the fixed frame 12 to move upward to the set position through the second linear motor 11. During the upward movement of the fixed frame 12, the end of the wire harness is guided by the guide groove 18 on the surface of the guide plate 17, so that the end of the wire harness is located between the two stripping knives 14, and then the PLC controller 3 controls the second linear motor 11 to work, and the second linear motor 11 drives the fixed frame 12 to move to the left through the sensing component 19. At the same time, the PLC controller 3 controls the laser generator 15 to work. Since the end of the wire harness is located in the fixed frame 12 at this time, it will hinder the laser receiver 16 from receiving the laser signal. When the second linear motor 11 drives the laser receiver 16 and the laser generator 15 to separate from the end of the wire harness, the laser signal emitted by the laser generator 15 will be received by the laser receiver 16, and the laser After receiving the laser signal, the optical receiver 16 will control the second linear motor 11 and the laser generator 15 to stop working immediately through the PLC controller 3, and then the PLC controller 3 controls the second linear motor 11 to drive the fixed frame 12 and other components to move in the opposite direction for a certain period of time at a set speed (for example, when it is necessary to cut a five-centimeter-long insulating layer 25, by setting the second linear motor 11 to move at a speed of one centimeter per second for five seconds, it will drive the stripping knife 14 to move to a position five centimeters away from the end of the wire harness). Then the PLC controller 3 controls the lateral electric push rods 13 on both sides to work, so that the lateral electric push rods 13 drive the two stripping knives 14 to move in a direction close to each other to a set distance, and use the stripping knife 14 to cut a certain depth at the specified position of the wire harness. Then the PLC controller 3 controls the moving end of the second linear motor 11 to continue to move to the left, and the second linear motor 11 squeezes and pushes a certain length of the insulating layer 25 from the wire harness through the stripping knife 14. Then the PLC controller 3 controls the lifting electric push rod 102 to drive the fixed frame 12 to move downward to the initial position;

[0043] When the turntable 5 drives the stripped wire harness to align with the crimping part of the terminal 7, the PLC controller 3 will control the corresponding first linear motor 81 to work, and the first linear motor 81 will drive the wire harness to move toward the terminal 7 through the automatic clamp 82, so that the conductor of the wire harness is inserted into the crimping part of the terminal 7, and then the PLC controller 3 controls the upper hydraulic cylinder 35 to work, and the upper hydraulic cylinder 35 drives the upper crimping seat 36 to move downward, and the crimping part of the terminal 7 is squeezed by the mutual cooperation of the upper and lower crimping seats 36. The crimping part of the crimping terminal 7 is crimped to connect the wiring harness and the wiring terminal 7 together. Then the PLC controller 3 controls the upper hydraulic cylinder 35 to drive the upper crimping seat 36 to move upward to the initial position, and controls the lower hydraulic cylinder 35 to drive the lower crimping seat 36 to be recovered into the storage groove 34. Then the PLC controller 3 controls the fixed frame 12 to continue to move to the bottom of the wiring harness (the moving method refers to the above moving steps), and controls the micro electric push rod 49 to drive the conical seat 50 and the card slot 51 to separate, and then the PLC controller 3 controls the corresponding The first linear motor 81 and the automatic clamp 82 drive the assembled wiring harness to move toward the turntable 5, and the wiring harness drives the terminal block 7 to move to the right together. Since the width of the terminal block 7 is greater than the width of the fixed frame 12, during the movement of the wiring harness to the right, the terminal block 7 will squeeze the fixed frame 12, and the fixed frame 12 will drive the induction box 191 below to move to the right together (the second linear motor 11 is in a self-locking state at this time, and will drive the sliding block 192 to be relatively still through the square plate 20), so that the sliding block 192 is in the induction box 19 1 slides relatively to the left, the sliding block 192 drives the wheel frame 23 and the metal wheel 24 to move relatively to the left in the induction box 191 through the bending rod 22, and the metal wheel 24 stops rotating after rotating to a certain angle through the cooperation of the blocking rod 26 and the left stop block 28, and the insulating layer 25 on the surface of the metal wheel 24 contacts the induction plate 29 above, and the first linear motor 81 drives the wiring harness to gradually move to the right through the automatic clamp 82, and the interaction force between the terminal 7 at the left end of the wiring harness and the fixed frame 12 becomes larger and larger;

[0044] When the connection performance between the wiring harness and the terminal block 7 is poor, the terminal block 7 will be separated from the conductor of the wiring harness during the process of the first linear motor 81 driving the wiring harness and the terminal block 7 to move to the right, and the induction box 191 will move rapidly to the left under the elastic force of the spring, and the friction between the induction box 191 and the metal wheel 24 will drive the metal wheel 24 to rotate counterclockwise, so that the metal part of the metal wheel 24 will contact the induction plate 29. At this time, the metal wheel 24 is electrically connected to the external power supply through the conductive slip ring assembly. When the metal wheel 24 contacts the induction plate 29, an electrical signal will be transmitted to the PLC controller 3. In the subsequent angle motor 6 driving After the wire harness moves to the bottom of the recycling rack 42, the PLC controller 3 controls the third electric push rod 43 to drive the adjusting motor 44, the fourth linear motor 45 and the electric clamp 46 to move downward together, and uses the electric clamp 46 to clamp the problematic wire harness, and at the same time controls the corresponding automatic clamp 82 to release the wire harness, and then the adjusting motor 44 drives the fourth linear motor 45 and the electric clamp 46 to rotate ninety degrees clockwise, so that the problematic wire harness moves to the top of the recycling box 47 at the rear side, and then the PLC controller 3 controls the electric clamp 46 to separate, and the problematic wire harness will fall into the recycling box 47 at the rear under the action of gravity;

[0045] When the connection performance between the terminal block 7 and the wiring harness is good, after the first linear motor 81 drives the automatic clamp 82 to move to the right, the PLC controller 3 will control the first electric push rod 52 to drive the support frame 101 and the induction box 191 and other components to move to the right to the set position, and then the PLC controller 3 controls the lifting electric push rod 102 to drive the fixed frame 12 to move downward, so that the fixed frame 12 and the wiring harness are separated, and then the first linear motor 81 drives the wiring harness to continue to move to the right, so that the terminal block 7 at the left end of the wiring harness is squeezed to the first pressure sensor 31, and the first pressure sensor 31 will control the first linear motor 81 to stop working, and then the PLC controller 3 controls the angle motor 6 to drive the wiring harness with good connection performance to rotate to the bottom of the detection component 37, and then the PLC controller 3 controls the second electric push rod 372 to work, and the second electric push rod 372 drives the lifting plate 38 to move downward, and the lifting plate 38 will drive the conduction block 39 to move downward and contact the crimping part of the terminal block 7. The conductor inside the wiring harness can be electrically connected to the conduction block 39 through the crimping part, and at the same time the lifting plate 38 will The conductive wheel 41 is driven to contact the insulating layer 25 of the wiring harness, and then the PLC controller 3 controls the third linear motor 40 to work. The third linear motor 40 drives the conductive wheel 41 to move along the wiring harness in the direction away from the terminal 7 (a small section of the insulating layer 25 is stripped off at the end of the wiring harness away from the terminal 7, so that the internal conductor of the wiring harness leaks out). When the conductive wheel 41 moves to the end of the wiring harness away from the terminal 7, it will contact the internal conductor of the wiring harness. The conductive wheel 41 is electrically connected to the external power supply through the conductive slip ring assembly. When the conductor and the terminal 7 When the crimping part is in good contact, the external current will be transmitted to the PLC controller 3 through the conduction wheel 41, the internal conductor of the wiring harness, and the conduction block 39, indicating that the conductive performance of the wiring harness terminal 7 and the wiring harness is good. When the PLC controller 3 does not receive the electrical signal from the conduction block 39 within the set time, the PLC controller 3 will control the wiring harness to rotate to the bottom of the recovery rack 42, and repeat the above working steps to place the problematic wiring harness in the recovery box 47 on the rear side for storage, and the good wiring harness will be placed in the recovery box 47 on the front side for storage.
