[0031] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0032] Reference Figures 1-7 As shown, an electronic wire harness pre-assembly device includes a base 1. A wire feeding reel 2 is fixedly connected to the upper end of the base 1. A conveying assembly 3, a first clamping assembly 4, a thumb cylinder 15, and a second clamping assembly 10 are sequentially arranged on the upper end of the base 1 to the right of the wire feeding reel 2. A U-shaped frame 17 is fixedly connected to the upper end of the base 1 near the right side of the first clamping assembly 4. A second hydraulic rod 18 is fixedly installed on the inner top of the U-shaped frame 17. A cutting blade 19 is fixedly connected to the output end of the second hydraulic rod 18. Two sliding grooves 5 are opened at the upper end of the base 1.

[0033] Furthermore, the wire unwinding reel 2 is driven by a motor and is used to unwind the electronic wire harness.

[0034] Furthermore, the first clamping assembly 4 includes a fixed base 401 fixedly connected to the upper end of the base 1. A wire hole 402 is provided through the left end of the fixed base 401, and a first mounting groove 403 is provided on the right end of the fixed base 401 above the wire hole 402. Two first electric push rods 404 are fixedly installed on the inner top of the first mounting groove 403, and a first pressure block 405 is fixedly connected to the output end of the first electric push rod 404.

[0035] Furthermore, the second clamping assembly 10 includes a movable base 1001. A positioning line hole 1002 is provided at the left end of the movable base 1001. A contact sensor 1004 is provided on the inner right side of the positioning line hole 1002. A second mounting groove 1003 is provided at the left end of the movable base 1001 above the positioning line hole 1002. Two second electric push rods 1005 are fixedly mounted on the inner top of the second mounting groove 1003. A second pressure block 1006 is fixedly connected to the output end of each second electric push rod 1005. Storage grooves 1007 are provided at both the front and rear ends of the movable base 1001. The internal sliding connection of 007 is a third slider 1009. The left end of the third slider 1009 is fixedly connected to a fixed frame 1010. The internal rotating connection of the fixed frame 1010 is a second threaded rod 1011. The outer surface of the second threaded rod 1011 is threadedly connected to a fourth slider 1013. The left end of the fourth slider 1013 is fixedly connected to a connecting plate 1014. The opposite ends of the two connecting plates 1014 are fixedly connected to arc-shaped cutters 1015. The ends of the two fixed frames 1010 that are far apart from each other are fixedly installed with a third motor 1012 for driving the rotation of the second threaded rod 1011.

[0036] Furthermore, the conveying assembly 3 includes two support frames 301 fixedly connected to the upper end of the base 1. An adjustment groove 302 is provided through the front end of the support frame 301. A first threaded rod 303 is rotatably connected inside the adjustment groove 302. One end of the first threaded rod 303 passes through the upper end of the adjustment groove 302 and is fixedly connected to a knob 308. A lifting block 304 is threadedly connected to the outer surface of the first threaded rod 303. A rotating shaft 305 is rotatably connected between the two support frames 301 and between the two lifting blocks 304. A conveying wheel 306 is fixedly connected to the outer surface of the rotating shaft 305. A first motor 307 for driving the lower rotating shaft 305 to rotate is fixedly installed at the front end of the front support frame 301.

[0037] Furthermore, the conveyor wheel 306 is made of rubber and has strong friction. By rotating the knob 308, the first threaded rod 303 is driven to raise the lifting block 304, which increases the distance between the two conveyor wheels 306. At this time, the electronic wire harness can be passed between the two conveyor wheels 306. Then, by rotating the knob 308 in the opposite direction, the lifting block 304 is lowered to clamp the electronic wire harness between the two conveyor wheels 306 and fix it. The first motor 307 drives the lower conveyor wheel 306 to rotate. Under the action of the friction between the two conveyor wheels 306, the wire harness can be pushed to the right, thereby conveying the wire harness.

[0038] Furthermore, a lead screw 6 is rotatably connected inside the front slide groove 5, and a second motor 601 for driving the lead screw 6 to rotate is fixedly installed at the right end of the base 1. A first slider 7 is threadedly connected to the outer surface of the lead screw 6. A guide rod 8 is fixedly connected inside the rear slide groove 5, and a second slider 9 is slidably connected to the outer surface of the guide rod 8. The upper ends of the second slider 9 and the first slider 7 are fixedly connected to the lower end of the movable seat 1001.

[0039] Furthermore, by driving the lead screw 6 to rotate via the second motor 601, the first slider 7 and the second slider 9 can cause the movable seat 1001 to move closer to or away from the fixed seat 401. The fixed seat 401 is in close contact with the support frame 301, and the movable seat 1001 is in close contact with the fixed seat 401 in the initial state.

[0040] Furthermore, both the wire hole 402 and the positioning wire hole 1002 are directly aligned with the conveying area between the two conveying wheels 306 and are consistent with the diameter of the processed wire harness. In the initial state of the moving seat 1001, one end of the electronic wire harness on the wire feeding reel 2 is sequentially passed between the two conveying wheels 306, then through the wire hole 402, and finally abuts against the contact sensor 1004, thus completing the initial placement of the wire harness. When the contact sensor 1004 contacts the end of the wire harness, it sends an electrical signal to the external control device. At this time, the external control device will activate the second electrical... The push rod 1005 drives the second pressure block 1006 to descend and press and fix one end of the wire harness. Then, the second motor 601 drives the lead screw 6 to rotate, so that the second slider 9 and the first slider 7 drive the moving seat 1001 away from the fixed seat 401. During this process, the unwinding reel 2 and the conveying assembly 3 will simultaneously unwind and convey the wire harness. When the length of the wire harness between the moving seat 1001 and the fixed seat 401 is consistent with the required cutting length, the second motor 601 stops running. At this time, the first electric push rod 404 drives the first pressure block 405 to press down and fix the wire harness.

[0041] Furthermore, the upper end of the base 1 is located between the second clamping assembly 10 and the first clamping assembly 4 and is fixedly connected to an electric slide rail 11 via a bracket. The electric slide rail 11 is slidably connected to a slide block 12. Two first hydraulic rods 13 are fixedly installed at the lower end of the slide block 12. The output end of the first hydraulic rods 13 is fixedly connected to a lifting plate 14. A thumb cylinder 15 is fixedly installed at the lower end of the lifting plate 14.

[0042] Furthermore, two hydraulic cylinders 1008 are fixedly installed on the right end of the movable seat 1001. The output ends of the two hydraulic cylinders 1008 pass through the right end of the movable seat 1001 and are fixedly connected to the right ends of the two third sliders 1009.

[0043] Furthermore, after the two pressure blocks clamp and fix the wire harness, the hydraulic cylinder 1008 will push the third slider 1009 to move, so that the fixing frame 1010 extends out of the storage groove 1007. The extension length of the fixing frame 1010 is the same as the length of the wire harness that needs to be stripped. After the fixing frame 1010 extends out of the storage groove 1007, the third motor 1012 will drive the second threaded rod 1011 to rotate, so that the two arc-shaped cutters 1015 approach each other until they close, thereby cutting the outer sheath of the wire harness. The size of the arc-shaped cutter 1015 is adapted to the thickness of the outer sheath of the wire harness to avoid over-cutting.

[0044] Furthermore, during the process of the arc-shaped cutter 1015 cutting the wire harness, the first hydraulic rod 13 will synchronously drive the thumb cylinder 15 to move down, so that the two grippers of the thumb cylinder 15 are located on both sides of the wire harness. After the thumb cylinder 15 reaches the target position, the two grippers start to move and clamp the middle of the wire harness.

[0045] Furthermore, guide grooves 1016 are provided at the top and bottom inner sides of the storage groove 1007, and guide blocks 1017 are fixedly connected to the upper and lower ends of the third slider 1009. The guide blocks 1017 are slidably connected to the inside of the guide grooves 1016.

[0046] Furthermore, a waste collection trough 16 is provided through the upper end of the base 1 between the two sliding grooves 5.

[0047] Furthermore, after the two arc-shaped cutters 1015 close, the second electric push rod 1005 will drive the second pressure block 1006 to reset. At this time, the second motor 601 drives the moving seat 1001 away from the fixed seat 401, thereby causing the arc-shaped cutter 1015 to pull the cut wire harness outer sheath from the cut and separate it from the wire harness, thus completing the wire harness stripping. After the wire harness stripping is completed, the arc-shaped cutter 1015 automatically resets, and the stripped outer sheath will fall into the waste collection tank 16. The bottom of the waste collection tank 16 is equipped with a waste collection box for collecting waste.

[0048] Furthermore, there is sufficient distance between the two chutes 5 and the waste collection trough 16 to prevent waste from falling into the interior of the chutes 5.

[0049] Furthermore, after the wire harness is stripped, the second hydraulic rod 18 will drive the cutting blade 19 to descend and cut the end of the wire harness near the wire hole 402, thereby achieving fixed-length cutting of the wire harness. After cutting, the slide block 12 is moved by the electric slide rail 11, which enables the thumb cylinder 15 to move the clamped wire harness to the next process.

[0050] Furthermore, all motors in this solution are servo motors, and the operation of the motors, hydraulic cylinders, and hydraulic rods is controlled by a PLC. Through the precise control of each driving component by the PLC, the precise positioning of each component during the movement process can be achieved.

[0051] Working principle: In use, one end of the electronic wire harness on the wire feeding reel 2 is passed sequentially between the two conveying rollers 306, then through the wire hole 402, and then abuts against the contact sensor 1004 to complete the initial placement of the wire harness. When the contact sensor 1004 contacts the end of the wire harness, it sends an electrical signal to the external control device. At this time, the external control device will activate the second electric push rod 1005 to drive the second pressure block 1006 to descend and press and fix one end of the wire harness. Then, the second motor 601 drives the lead screw 6 to rotate, causing the second slider 9 and the first slider 7 to move the moving seat 1001 away from the fixed seat 401. During this process, the wire feeding reel 2 and the conveying assembly 3 will synchronously move the wire harness. During unwinding and conveying, when the length of the wire harness between the moving seat 1001 and the fixed seat 401 matches the required cutting length, the second motor 601 stops operating. At this time, the first electric push rod 404 drives the first pressure block 405 to press down and fix the wire harness. After the two pressure blocks have pressed and fixed the wire harness, the hydraulic cylinder 1008 will push the third slider 1009 to move, so that the fixing frame 1010 extends out of the storage groove 1007. The extension length of the fixing frame 1010 is the same as the length of the wire harness that needs to be stripped. After the fixing frame 1010 extends out of the storage groove 1007, the third motor 1012 will drive the second threaded rod 1011 to rotate, so that the two arc-shaped cutters 1015 interact with each other. The curved cutter 1015 approaches and closes, cutting the outer sheath of the wire harness. During the cutting process, the first hydraulic rod 13 simultaneously drives the thumb cylinder 15 downward, positioning the two grippers of the thumb cylinder 15 on either side of the wire harness. After the thumb cylinder 15 reaches the target position, the two grippers begin to move, clamping the middle of the wire harness. After the two curved cutters 1015 close, the second electric push rod 1005 drives the second pressure block 1006 to reset. At this time, the second motor 601 drives the moving seat 1001 away from the fixed seat 401, causing the curved cutter 1015 to pull the cut wire harness sheath away from the wire harness from the cut, thus completing the wire stripping process. After the wire harness is stripped, the arc-shaped cutter 1015 automatically resets, and the stripped outer sheath falls into the waste collection trough 16. The bottom of the waste collection trough 16 is equipped with a waste collection box for collecting waste. After the wire harness is stripped, the second hydraulic rod 18 drives the cutting blade 19 to descend and cut the end of the wire harness near the wire hole 402, thereby achieving fixed-length cutting of the wire harness. After cutting, the slide block 12 is moved by the electric slide rail 11, which enables the thumb cylinder 15 to move the clamped wire harness to the next process. At the same time, all components reset, and then the wire harness is continued to be transported by the conveying assembly 3, so that one end of the wire harness contacts the contact sensor 1004 and repeats the above processing steps.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
