Description

Technical Field

[0001] The present invention relates to the technical field of automobile wiring harnesses, and in particular to an automobile multi-channel low-voltage wiring harness detection device and a use method thereof. Background Art

[0002] Automotive low-voltage wiring harnesses distribute power from the power supply to various electrical consumers and transmit signals from these consumers back to the control unit. During the production process, testing can be used to screen out substandard wiring harnesses, preventing vehicle failures caused by wiring harness issues.

[0003] The inspection of automotive low-voltage wiring harnesses can be divided into appearance inspection, electrical performance test and mechanical performance test. During the test, the staff is required to fix the two ends of the low-voltage wiring harness, and then perform different tests on the low-voltage wiring harness in the straightened state. However, when testing multiple low-voltage wiring harnesses, the low-voltage wiring harness will be twisted due to external friction during movement. Therefore, when fixing the low-voltage wiring harness, the staff not only needs to fix the round terminals on both sides in turn, but also needs to restore the twisting of the low-voltage wiring harness during the extension process to avoid affecting the test results, thereby affecting the test efficiency during the multi-way low-voltage wiring harness inspection. Multiple groups of low-voltage wiring harnesses also need to be observed by the naked eye of the staff in turn, which can easily cause visual fatigue of the staff, thereby ignoring small damage on the outer skin of the low-voltage wiring harness, and when performing different tests, the multiple low-voltage wiring harnesses need to be transferred between different instruments.

[0017] A vehicle multi-channel low-voltage wiring harness detection device, wherein the method for using the vehicle multi-channel low-voltage wiring harness detection device comprises the following steps:

[0018] Step 1: Install the ring terminal at one end of the multi-way low-voltage wire harness onto the copper pillar 1 in sequence.

[0019] Step 2: Start the linear module 1, drive the movable plate and the wire pulley to move toward the power box, and put the multi-channel low-voltage wire harness into the slot plate under the action of the movement and rotation of the wire pulley. Then the electric telescopic rod is started, driving the pressure plate at the bottom of the movable shaft to move downward and contact the ring terminal of the multi-channel low-voltage wire harness, so that the multi-channel low-voltage wire harness is away from the copper column. The ring terminal at one end gradually fits with the bottom surface of the pressure plate and is in a horizontal state.

[0020] Step 3: Start the power box to drive the screw to rotate. Under the action of the thread, the screw drives the slider 1 and the dynamometer close to the slot plate. The dynamometer descends with the cooperation of the pin shaft and the inclined section of the limit slot 2, so that the hook on the dynamometer moves to the bottom of the unfixed ring terminal of the low-voltage wiring harness.

[0021] Step 4: Start the power box to drive the screw to rotate in the opposite direction, so that the screw drives the slider 1 and the dynamometer to move toward the power box. With the cooperation of the slider 2, the spring, the pin shaft and the limit slot 2, the dynamometer rises rapidly under the guidance of the inclined section of the limit slot 2, thereby hooking the hook on the dynamometer into the unfixed ring terminal of the low-voltage wiring harness, and then the multi-channel low-voltage wiring harness is straightened under the action of the screw continuing to drive the slider 1 and the dynamometer to slide.

[0022] Step 5: Start the electric telescopic rod 3 to push the lifting plate up, thereby pushing the copper column 2 upward until it contacts the ring terminal of the multi-channel low-voltage wiring harness hooked by the multimeter, and then use the multimeter to test the electrical performance of the multi-channel low-voltage wiring harness in turn.

[0023] Step 6: After the multi-channel low-voltage wiring harness is straightened, start the power box again, so that the slider 1 and the tension gauge continue to move toward the power box under the action of the screw rod. Since one end of the multi-channel low-voltage wiring harness is fixed by the copper column 1, the tension value when the tension gauge moves to pull the low-voltage wiring harness can be displayed on the tension gauge, thereby performing tension tests on the multi-channel low-voltage wiring harness in turn.

[0024] Step 7: After the tensile test, start the linear module 2 to drive the mobile frame and the industrial camera to move toward the fixed seat, scan the surface of the low-voltage wire harness, and transmit it to the external analysis equipment for analysis. Then start the electric telescopic rod 2 to push the rack. When the rack slides, the gear drives the rotating wheel to rotate. The rotating wheel drives the arc seat and the copper column to rotate, and drives the low-voltage wire harness to rotate. The industrial camera scans the entire outer skin of the multi-channel low-voltage wire harness during the back and forth movement under the action of the linear module 2.

[0025] As described above, the characteristics and advantages of the automotive multi-channel low-voltage wiring harness detection device of the present invention are:

[0026] Through the arrangement of the copper column and the slot plate, when installing a multi-channel low-voltage wiring harness, it is only necessary to sleeve the ring terminal on one side of the low-voltage wiring harness onto the copper column one in sequence, and drive the movable plate to move along the slot plate through the linear module. The wire wheel on the movable plate brings the low-voltage wiring harness outside the slot plate into the slot plate under the action of rotation, thereby achieving the effect of wiring management. In addition, the staff only needs to sleeve the ring terminal at one end of the multi-channel low-voltage wiring harness onto the copper column one, without having to fix the two ends of the multi-channel low-voltage wiring harness in sequence, and there is no need to manually restore the low-voltage wiring harness in a twisted state, which saves time and effort.

[0027] Through the cooperation of the pin shaft and the second limiting groove, when the dynamometer approaches the low-voltage wiring harness, the hook at the tail of the dynamometer will be lowered to the bottom of the unfixed ring terminal of the low-voltage wiring harness under the cooperation of the pin shaft and the second limiting groove. Then the screw drives the slider to move in the direction close to the power box. At the same time, the dynamometer gradually rises under the cooperation of the slider second, the spring, the pin shaft and the second limiting groove, so that the hook at the tail of the dynamometer is hooked into the unfixed ring terminal of the low-voltage wiring harness during the rising process. When the dynamometer continues to move, the hook and the ring terminal cooperate to gradually straighten the low-voltage wiring harness, thereby realizing the automatic straightening of multiple low-voltage wiring harnesses in sequence, saving time and effort.

[0028] Through the cooperation of copper pillar one and the force gauge, after the multi-channel low-voltage wiring harness is straightened under the cooperation of copper pillar one and the force gauge, the electric telescopic rod three is started to drive the lifting plate to rise, so that the multiple copper pillars two are in contact with the ring terminals on one side of the multi-channel low-voltage wiring harness. Since the ring terminals on the other side of the multi-channel low-voltage wiring harness are connected to wire one through copper pillar one, multiple multimeters are started at this time to perform electrical performance tests on the multi-channel low-voltage wiring harness, and the power box can be started to drive the screw rod to rotate further in the opposite direction, so that the slider one continues to drive the force gauge to move through the fixed frame and the slider two. When the force gauge moves to pull the low-voltage wiring harness, the value of the tension can be displayed on the force gauge, thereby achieving the effect of performing tension tests on the multiple low-voltage wiring harnesses in sequence, and under the precise movement of the screw rod and the slider one, the position of the force gauge can be slightly adjusted, thereby adjusting the tension of the force gauge on the multiple low-voltage wiring harness, making the test more accurate.

[0029] Through the cooperation of the rack and the gear, when the multiple low-voltage wiring harnesses are straightened under the fixation of the copper column 1 and the dynamometer, the linear module 2 starts and drives the mobile frame to move toward the fixed seat, thereby driving multiple industrial cameras to move along the path of the slot plate. The surface of the low-voltage wiring harness is carefully observed by the industrial camera to avoid overlooking the small damage on the surface of the low-voltage wiring harness when observing with the naked eye. The electric telescopic rod 2 can also be used to push the rack so that the rack drives the rotating wheel to rotate through the gear, and the rotating wheel drives the arc seat and the copper column 1 to rotate, driving the low-voltage wiring harness to rotate, so that the industrial camera can observe the entire outer skin of the multiple low-voltage wiring harnesses during the back and forth movement to avoid omissions. At the same time, the multiple low-voltage wiring harnesses rotate together, and there is no need to rotate them one by one for inspection, which saves time and effort during inspection.

[0050] In combination with the above embodiments, the entire working process and working principle of the above embodiments are as follows:

[0051] The initial state is:

[0052] The electric telescopic rod 2 402 is in a retracted state, the rack 403 does not move, the rotating wheel 303 does not rotate, the copper column 1 305 in the arc seat 304 is in a vertical upward state, the movable plate 307 is located on the side of the linear module 1 306 close to the fixed seat 2, the power box 309 is not powered, the slider 1 311 is located on the side of the screw rod 310 close to the fixed seat 2, the spring 504 is in an extruded state, the slider 2 503 is located at the top of the limit slot 1 502, the movable frame 406 is located on the side of the linear module 2 405 close to the power box 309, the electric telescopic rod 3 411 is not extended, and the height of the copper column 2 413 is lower than the slot plate 302.

[0053] The working status is:

[0054] Install the wiring harness:

[0055] When testing a multi-channel low-voltage wiring harness, the staff will sequentially place the ring terminal at one end of the multi-channel harness on the copper column 305, and monitor whether the end of the wiring harness close to the copper column 305 is located between a set of wire wheels 308 to complete the installation of the wiring harness.

[0056] Automatic cable management:

[0057] When one end of the multi-channel low-voltage wire harness is sleeved on the copper column 1 305 through the ring terminal, the linear module 1 306 is started, driving the movable plate 307 to move toward the power box 309, so that the movable plate 307 drives the top wire wheel 308 to move synchronously. In the process of the wire wheel 308 following the movable plate 307 to move toward the power box 309, the outer skin of the wire harness outside the slot plate 302 and the wire wheel 308 produce friction. Under the action of rotation, multiple wire wheels 308 bring the wire harness into the slot of the slot plate 302. At the same time, the continuous rotation of the wire wheel 308 Rotation can prevent excessive friction between the outer skin of the wire harness and the wire wheel 308. During this process, the twisted wire automatically recovers under the action of elastic force until the movable plate 307 moves to the side close to the power box 309 under the drive of the linear module 306. The multi-channel low-voltage wire harness is completely placed in the groove of the groove plate 302, achieving the effect of wire management. The staff only needs to put the ring terminal at one end of the multi-channel low-voltage wire harness on the copper column 305, and there is no need to fix the two ends of the multi-channel low-voltage wire harness in turn. At the same time, there is no need to manually restore the low-voltage wire harness in a twisted state, saving time and effort.

[0058] Mobile hook:

[0059] When the ring terminal at one end of the multi-way low-voltage wiring harness is sleeved on the copper pillar 305 and the multi-way low-voltage wiring harness is inserted into the slot plate 302 under the action of the wire wheel 308, the unfixed ring terminal of the multi-way low-voltage wiring harness is located at the end of the slot plate 302 away from the rotating wheel 303, and the ring terminal extends out of the slot of the slot plate 302. At this time, the ring terminal of the multi-way low-voltage wiring harness away from the copper pillar 305 will be in an inclined state due to excessive twisting during the wiring harness production process. At this time, the movable axis of the electric telescopic rod 314 extends downward, pushing the pressure plate to contact the ring terminal of the multi-way low-voltage wiring harness away from the copper pillar 305, so that the ring terminal of the multi-way low-voltage wiring harness away from the copper pillar 305 is pressed against the bottom surface of the pressure plate, thereby being in a horizontal state. Then the power box 309 is started, and the motor in the power box 309 drives the screw rod 310 to rotate, so that the screw rod 310 drives the slider 311 close to the screw rod 310 under the action of the thread. When the pin 507 enters the portion with the inclined section in the limit groove 506, the pin 507 moves downward in cooperation with the inclined section, thereby driving the slider 2 503 and the limit groove 1 502 to move downward, so that the two sliders 503 drive the tension gauge 312 to move downward, and at the same time further squeeze the spring 504 until the tension gauge 312 moves to the end of the screw rod 310 away from the power box 309 under the drive of the slider 1 311. At the same time, the tension gauge 312 continues to descend in cooperation with the pin 507 and the limit groove 2 506, so that the height of the hook on the tension gauge 312 is lower than the slot plate 302, and at this time the hook is located below the unfixed ring terminal of the low-voltage wiring harness.

[0060] It is to be noted that the electric telescopic rod 314 extends downward to drive the pressure plate to contact the connection between the multi-channel low-voltage wire harness and the ring terminal, and contacts the ring terminal part to change its angle to facilitate hooking;

[0061] The screw rod 310 drives the slider 1 311 close to the slot plate 302. In the process of the slider 1 311 driving the dynamometer 312 to move synchronously with the cooperation of the fixed frame 501 and the slider 2 503, the dynamometer 312 moves toward the final position of the slot plate 302, so that the front end of the hook thereon does not correspond to the center point of the circular ring terminal of the multi-channel low-voltage wiring harness, so that the hook is more biased toward the direction of the slot plate 302, so that the dynamometer 312 has a certain displacement space to hook the circular ring terminal of the multi-channel low-voltage wiring harness when it moves upward with the help of the limiting groove 2 506.

[0062] Straighten the low-voltage wiring harness:

[0063] When the hook of the dynamometer 312 moves to the bottom of the unfixed ring terminal of the low-voltage wiring harness, the power box 309 drives the screw rod 310 to rotate in the opposite direction, so that the screw rod 310 drives the slider 1 311 to move toward the power box 309, so that the slider 1 311 drives the dynamometer 312 to move toward the power box 309 through the fixed frame 501 and the slider 2 503. At the same time, the dynamometer 312 rises rapidly under the guidance of the inclined section of the limit groove 2 506 under the cooperation of the slider 2 503, the spring 504, the pin 507 and the limit groove 2 506, so that the tail of the dynamometer 312 rises rapidly. During the rising process, the hook is hooked into the unfixed ring terminal of the low-voltage wiring harness, and then the slider 311 continues to drive the dynamometer 312 to move, so that the pin shaft 507 slides out of the inclined section of the limit groove 506. At this time, since one end of the low-voltage wiring harness is fixed in cooperation with the ring terminal and the copper column 305, the hook and the ring terminal will gradually straighten the low-voltage wiring harness when the dynamometer 312 moves. Then the power box 309 is powered off, so that the multiple low-voltage wiring harnesses are in a state of being straightened by the copper column 305 and the dynamometer 312, thereby realizing automatic straightening of the multiple low-voltage wiring harnesses, saving time and effort.

[0064] Electrical testing:

[0065] After the multi-channel low-voltage wiring harness is straightened with the cooperation of copper pillar 1 305 and dynamometer 312, electric telescopic rod 311 is started to drive lifting plate 412 to rise, so that lifting plate 412 drives copper pillar 2 413 to rise, thereby making multiple copper pillars 2 413 contact with the ring terminals of the multi-channel low-voltage wiring harness hooked by multimeter 408. Since the ring terminals on the other side of the multi-channel low-voltage wiring harness are connected to wire 1 409 through copper pillar 1 305, multiple multimeters 408 are started at this time, and the electrical performance of the multi-channel low-voltage wiring harness can be tested in turn, which is more convenient to use.

[0066] Tensile test:

[0067] When the multi-channel low-voltage wiring harness is straightened under the action of copper column 1 305 and the dynamometer 312, the power box 309 can be started so that the power box 309 drives the screw rod 310 to rotate further in the opposite direction, so that the slider 1 311 continues to drive the dynamometer 312 to move through the fixed frame 501 and the slider 2 503. At this time, since one end of the multi-channel low-voltage wiring harness is fixed by copper column 1 305, the value of the tension when the dynamometer 312 moves to pull the low-voltage wiring harness can be displayed on the dynamometer 312, thereby achieving the effect of performing tension tests on the multi-channel low-voltage wiring harness in sequence, and under the precise movement of the screw rod 310 and the slider 1 311, the position of the dynamometer 312 can be finely adjusted to adjust the tension of the dynamometer 312 on the multi-channel low-voltage wiring harness, so that the test is more accurate.

[0068] Check the low voltage wiring harness:

[0069] After multiple low-voltage wiring harnesses are straightened under the fixation of copper column 1 305 and tensile gauge 312, linear module 2 405 starts and drives the movable frame 406 to move toward the fixed seat 2, thereby driving multiple industrial cameras 407 to move along the path of the slot plate 302, and then the surface of the low-voltage wiring harness is scanned by the industrial camera 407 and transmitted to the external analysis equipment for analysis, so as to avoid the situation where small damage on the surface of the low-voltage wiring harness is easily overlooked when observed with the naked eye.

[0070] Swivel Harness:

[0071] When inspecting the surface of the low-voltage wiring harness through the industrial camera 407, the electric telescopic rod 2 402 can be started, so that the electric telescopic rod 2 402 extends and pushes the rack 403 to slide inside the slide groove 401. When the rack 403 slides, the gear 404 drives the rotating wheel 303 to rotate, so that the rotating wheel 303 drives the arc seat 304 and the copper column 1 305 to rotate, thereby driving the low-voltage wiring harness to rotate through the cooperation between the copper column 1 305 and the circular ring terminal at one end of the low-voltage wiring harness. Since the hook at the tail end of the dynamometer 312 is usually designed to be rotatable, the multiple low-voltage wiring harnesses will rotate synchronously when the rotating wheel 303 rotates, so that the industrial camera 407 can observe the entire outer skin of the multiple low-voltage wiring harnesses in the process of moving back and forth under the action of the linear module 2 405 to avoid omissions. At the same time, the multiple low-voltage wiring harnesses rotate together, and there is no need to rotate them one by one for inspection, which saves time and effort during inspection.

[0072] Embodiment 2: A device for detecting a multi-channel low-voltage wiring harness for an automobile. A method for using the device for detecting a multi-channel low-voltage wiring harness for an automobile comprises the following steps:

[0073] Step 1: Install the ring terminal at one end of the multi-way low-voltage wire harness onto the copper pillar 305 in sequence.

[0074] Step 2: Start the linear module 306, drive the movable plate 307 and the wire pulley 308 to move toward the power box 309, and under the action of the movement and rotation of the wire pulley 308, the multi-channel low-voltage wire harness is put into the slot plate 302, and then the electric telescopic rod 314 is started, driving the pressure plate at the bottom of the movable shaft to move downward and contact the ring terminal of the multi-channel low-voltage wire harness, so that the multi-channel low-voltage wire harness away from the ring terminal at one end of the copper column 305 gradually fits into the bottom surface of the pressure plate and is in a horizontal state.

[0075] Step 3: Start the power box 309 to drive the screw rod 310 to rotate. Under the action of the thread, the screw rod 310 drives the slider 1 311 and the dynamometer 312 to approach the slot plate 302. The dynamometer 312 descends with the cooperation of the pin shaft 507 and the inclined section of the limit slot 2 506, so that the hook on the dynamometer 312 moves to the bottom of the unfixed ring terminal of the low-voltage wiring harness.

[0076] Step 4: Start the power box 309 to drive the screw rod 310 to rotate in the opposite direction, so that the screw rod 310 drives the slider 1 311 and the dynamometer 312 to move toward the power box 309. The dynamometer 312 rises rapidly under the guidance of the inclined section of the limit groove 2 506 under the cooperation of the slider 2 503, the spring 504, the pin 507 and the limit groove 2 506, thereby hooking the hook on the dynamometer 312 into the unfixed ring terminal of the low-voltage wiring harness, and then the multi-channel low-voltage wiring harness is straightened under the action of the screw rod 310 continuing to drive the slider 1 311 and the dynamometer 312 to slide.

[0077] Step 5: Start the electric telescopic rod 3 411 to push the lifting plate 412 upward, thereby pushing the copper column 2 413 upward until it contacts the ring terminal of the multi-channel low-voltage wiring harness hooked by the multimeter 408, and then use the multimeter 408 to test the electrical performance of the multi-channel low-voltage wiring harness in turn.

[0078] Step 6: After the multi-channel low-voltage wiring harness is straightened, the power box 309 is started again, so that the slider 1 311 and the tension gauge 312 continue to move toward the power box 309 under the action of the screw rod 310. Since one end of the multi-channel low-voltage wiring harness is fixed by the copper column 1 305, the value of the tension when the tension gauge 312 moves to pull the low-voltage wiring harness can be displayed on the tension gauge 312, thereby performing tension tests on the multi-channel low-voltage wiring harness in turn.

[0079] Step 7: After the tension test, start the linear module 2 405 to drive the movable frame 406 and the industrial camera 407 to move toward the fixed seat 2, scan the surface of the low-voltage wire harness, and transmit it to the external analysis equipment for analysis. Then start the electric telescopic rod 2 402 to push the rack 403. When the rack 403 slides, it drives the rotating wheel 303 to rotate through the gear 404. The rotating wheel 303 drives the arc seat 304 and the copper column 1 305 to rotate, and drives the low-voltage wire harness to rotate. The industrial camera 407 scans the entire outer skin of the multi-channel low-voltage wire harness during the back and forth movement under the action of the linear module 2 405.
