Description

Technical Field

[0001] The invention relates to the technical field of wire harness processing equipment, and in particular to automatic pressing equipment for outer conductors of wire harnesses. Background Art

[0002] In order to ensure the transmission performance of the data transmission line, the wiring harness used in new energy vehicles usually has a shielded aluminum foil layer inside to shield interference signals. The existing technology uses rotary cutting and peeling to process the shielded aluminum foil, but the existing technology has been found to still have some disadvantages during long-term use, such as: 1. After the shielding braided layer on the outer layer of the shielded aluminum foil in the wiring harness is turned outward on the shielding ring, the subsequent aluminum foil processing, center insulation layer stripping and center terminal crimping are all positioned by pressing the turned-out shielding braided layer. The stress points of the processing steps after rotary cutting and peeling of the shielding aluminum foil are concentrated on the turned-out shielding braided layer, and the shielding braided layer is easily broken at the root bend during multiple clamping and fixing processes; 2. After the turned-out shielding braided layer is clamped for multiple times, the cross-section of the wiring harness will transition from a circle to an ellipse, resulting in poor concentricity when pressing the center terminal and the outer conductor, and even in the case of serious deviation, the entire wiring harness will be directly scrapped.

DETAILED DESCRIPTION

[0026] 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.

[0027] like Figures 1 to 11 As shown, an automatic press-fitting device for outer conductors of a wire harness comprises a frame 1, a center terminal feeder 2, a clamping and positioning mechanism 3, an aluminum foil cutting and stripping mechanism 4 and a press-fitting and winding mechanism 5, wherein the center terminal feeder 2 is mounted on the frame 1 to automatically supply the center terminal of the wire harness to be press-fitted into the frame 1, the clamping and positioning mechanism 3 is mounted in the frame 1 and is used to adjust the processing station of the wire harness, the aluminum foil cutting and stripping mechanism 4 is mounted in the frame 1 and is used to groove and strip the shielding aluminum foil layer on the wire harness, and the press-fitting and winding mechanism 5 is mounted in the frame 1 to complete the automatic press-fitting of the wire harness and the center terminal and partially wind up the slotted shielding aluminum foil layer on the wire harness.

[0028] In this embodiment, the clamping and positioning mechanism 3 includes a motor 31, a screw 32 and a fixed clamp 33. The motor 31 is installed in the frame 1, and the screw 32 is installed on the output end of the motor 31. A fixed plate 34 is fixedly connected to the frame 1. The other end of the screw 32 is rotatably connected to the fixed plate 34. A guide rod 35 arranged parallel to the screw 32 is fixedly connected to the fixed plate 34. The fixed clamp 33 fixedly clamps the wire harness to be processed. The fixed clamp 33 is threadedly connected to the screw 32, and the fixed clamp 33 is also slidably arranged on the guide rod 35.

[0029] In this embodiment, the aluminum foil cutting and stripping mechanism 4 includes a second motor 401, a cam 402 and a knife holder 403. The second motor 401 is installed on the frame 1 through a mounting seat 404. The cam 402 is installed on the output shaft of the second motor 401. The output shaft of the second motor 401 passes through the mounting seat 404 and is threadedly mounted with a cross guide frame 405. The mounting seat 404 is also provided with a wedge frame 406 for limited sliding. A slide bar 407 is fixedly provided at the side end of the mounting seat 404. The lower end of the wedge frame 406 is slidably provided on the slide bar 407. The slide bar A spring 408 is sleeved between the end of the slide rod 407 and the wedge frame 406 on 407, the inclined end of the wedge frame 406 cooperates with the outer edge of the cam 402, and the end of the wedge frame 406 is bolted with a guide occlusal frame 409. The tool holder 403 is slidably set on the guide occlusal frame 409, and the tail cutting section of the tool holder 403 is also slidably set in the cross guide frame 405. The tool holder 403 is provided with a mounting groove 410, and a cutting knife 411 is adjustably installed in the mounting groove 410, and a grooving knife 412 is fixedly installed at the end of the tool holder 403.

[0030] It should be noted that the motor 1 31 and the motor 2 401 are both servo motors, and the working clamping end of the fixed clamp 33 cooperates with the outer side of the braided shielding layer turned outward on the wire harness;

[0031] The cross guide frame 405 is installed on the motor 2 401 through an elastic adapter, so that when the several tool holders 403 are in the process of being clamped, the cross guide frame 405 will move synchronously with the output end of the motor 2 401, and after the several tool holders 403 are clamped, the cross guide frame 405 will not continue to rotate with the output end of the motor 2 401.

[0032] In this embodiment, the width of the cutting knife 411 is greater than the width of the grooving knife 412. At the same time, there are four cutting knives 411. When the four cutting knives 411 are fully gathered together, the cutting edges thereof are closed circles, and the curved surface formed by the cutting edges of the cutting knife 411 and the grooving knife 412 in the horizontal direction is parallel to the end face of the wire harness.

[0033] It is worth mentioning that the outer edge of the cam 402 and the inclined surface end of the wedge-shaped frame 406 are in a small-inclination fit. That is, under the power transmission of the cam 402, the wedge-shaped frame 406 drives a plurality of tool holders 403 to perform variable-speed movement that is slow first and then fast, avoiding the tearing situation on both sides of the cut groove of the shielding aluminum foil layer due to the fast cutting speed of the grooving tool 412 at the start of cutting.

[0034] In this embodiment, the press-fitting and winding mechanism 5 includes a cylinder three 501, a winding part 502, and a "C"-shaped guide seat 503. The cylinder three 501 is installed on the frame 1 through a fixed seat 504. The output end of the cylinder three 501 is equipped with a strip-shaped mounting frame 505. Both ends of the strip-shaped mounting frame 505 are hinged with a push rod three 506. A push rod four 507 is hinged on the fixed seat 504. The other end of the push rod three 506 is limited and slidably arranged in the middle of the push rod four 507. The end of the push rod four 507 located above is fixedly connected with a press-fitting part 508. Two symmetrically arranged press-fitting heads 509 are hinged at the lower end of the press-fitting part 508. Both sides of the press-fitting part 508 are connected with the press-fitting heads 509 through tension springs 510. The end of the push rod four 507 located below is fixedly connected with a press-fitting seat 511. Feeding channels 512 are opened on both sides of the press-fitting seat 511. The guide seat 503 is fixedly connected to the fixed seat 504. An inclined-hole sliding frame 513 is slidably arranged in the guide seat 503. The inclined-hole sliding frame 513 is fixedly connected to the strip-shaped mounting frame 505. The winding part 502 is adjustably installed on the inclined-hole sliding frame 513.

[0035] In this embodiment, the winding part 502 can be arbitrarily adjusted in terms of angle and winding length in the installation opening on the inclined-hole sliding frame 513, and different models of the winding part 502 can also be replaced to adapt to the processing of wire harnesses of various specifications.

[0036] In this embodiment, the press-fitting seat 511 cooperates with the two press-fitting heads 509 in the vertical direction.

[0037] It should be noted that the working section of the winding part 502 is a lower-end arc-shaped concave surface. The working section of the winding part 502 corresponds to the remaining unslotted shielding aluminum foil in the horizontal direction. The upper end of the working section of the winding part 502 is adjustably installed through bolts, and the lower end of the winding part 502 cooperates with the wire harness shielding aluminum foil layer in the horizontal direction.

[0038] In addition, the feeding channels 512 cooperate with the central terminal feeder 2 in the horizontal direction.

[0039] Working process and principle: During use, the present invention first automatically supplies the wire harness center terminal material plate to be pressed into the frame 1 through the center terminal feeder 2, and then fixes the outward shielding braided layer of the wire harness on the fixed clamp 33, and starts the motor 1 31 so that its output end drives the lead screw 32 to rotate. Under the guidance of the guide rod 35, the end of the wire harness passes through the gap between two adjacent tool holders 403, so that the fixed clamp 33 moves to a position that cooperates with the aluminum foil cutting and stripping mechanism 4, and starts the motor 2 401 so that its output end drives the cam 402 to rotate, and drives the cross guide frame 405 at the end to move synchronously. In the initial stage, under the elastic force of the spring 408 , the lower end of the wedge frame 406 is against the side wall of the mounting seat 404, at which time the inner edge of the large diameter of the cam 402 contacts the wedge frame 406, and the movement of the cross guide frame 405 will drive a number of tool holders 403 to gather inward along the guide of the guide occlusal frame 409. After the cross guide frame 405 moves to the straight section of the tool holder 403, a number of tool holders 403 are clamped together, and the cross guide frame 405 will not continue to move with the output end of the motor 2 401. In the fully gathered state, the cutting knife 411 with a closed circular blade edge completely cuts off the shielding aluminum foil layer close to the end of the wire harness, and the grooving knife 412 cuts an arc-shaped opening on the shielding aluminum foil layer relatively far away from the end of the wire harness;

[0040] After the outer edge of the small diameter of the cam 402 contacts the wedge frame 406, the wedge frame 406 is pushed to slide backward, and the closed knife frame 403 is pulled through the guide bite frame 409. During the pulling back process, the shielding aluminum foil cut by the cutting knife 411 is directly peeled off, and the groove drawing knife 412 forms a groove on the shielding aluminum foil layer during the cutting process;

[0041] Start the motor 31 again so that its output end drives the motor 33 to move to the position matched with the press-fitting winding mechanism 5, directly start the cylinder 3 501 so that its output end drives the strip mounting frame 505 to extend forward, and the other end of the push rod 3 506 slides and pulls down in the push rod 4 507, driving the press-fitting part 508 and the press-fitting seat 511 to move toward each other, and the central terminal material of the wire harness placed in the press-fitting seat 511 is arranged under the tightening of the two press-fitting heads 509, and the wire harness is pressed and fitted on the wire harness. At the same time, the strip mounting frame 505 extends forward. During the process, the winding section 502 is also driven to slide forward in the guide seat 503 through the inclined hole sliding frame 513, and the winding blade at the lower end of the winding section 502 is placed between the shielding aluminum foil layer and the insulating layer through the end of the unslotted aluminum foil, and the unslotted aluminum foil completes the winding action in the arc-shaped concave surface of the winding section 502 until the outer diameter of the rolled-up shielding aluminum foil roll is consistent with the braided shielding layer. After the pressing and installation of the center terminal of the wire harness and the winding of the shielding aluminum foil are completed at the same time, the cylinder three 501 is started in reverse and the wire harness can be unloaded.

[0042] Based on the above, the present invention sets a clamping and adjusting mechanism 3, an aluminum foil cutting and stripping mechanism 4 and a pressing and winding mechanism 5 in the frame 1, and the output end of the motor 2 401 drives the cam 402 to rotate, and drives the cross guide frame 405 at the end to move synchronously, and the movement of the cross guide frame 405 in the inclined section of the knife frame 403 drives a plurality of knife frames 403 to clamp along the guide bite frame 409, and the cutting knife 411 and the groove knife 412 respectively completely cut off the shielding aluminum foil layer and cut out an arc opening, and finally the wedge frame 406 is pushed backward by the cam 402 to make the cut aluminum foil layer The shielding aluminum foil cut by the cutting knife 411 is directly peeled off, and the grooving knife 412 forms a groove on the shielding aluminum foil layer during the slicing process, and then drives the reeling part 502 to slide forward in the guide seat 503 through the output end of the cylinder 3 501 through the inclined hole sliding frame 513 to complete the reeling action of the ungrooved aluminum foil, so that the outer diameter of the rolled-up shielding aluminum foil roll is consistent with the braided shielding layer, thereby realizing the clamping force in the subsequent process, which is evenly distributed on both the turned-out shielding braided layer and the rolled-up shielding aluminum foil, ensuring that the turned-out root of the shielding braided layer will not be easily broken;

[0043] By distributing the clamping force to both the outward-turned shielding braided layer and the rolled-up shielding aluminum foil, the center terminal is synchronously pressed between the press-fit seat 511 and the two press-fit heads 509 to reduce the risk of the wire harness cross-section transitioning to an elliptical shape. At the same time, the concentricity of the center terminal and the outward-turned shielding braided layer and the shielding aluminum foil on the wire harness is ensured, thereby achieving concentricity between the center terminal and the outer conductor of the wire harness during subsequent press-fitting, thereby ensuring the signal transmission quality of the data transmission harness.

[0044] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
