Description

Technical Field

[0001] The invention relates to the technical field of cable crimping devices, and in particular to a crimping device for automobile wiring harness cables. Background Art

[0002] A wiring harness cable is a device that combines multiple cables or wires through components such as insulation layers, protective layers, and connectors to transmit power or signals. It usually includes protection and fixing devices and is widely used in automobiles, aerospace, industrial equipment, and consumer electronics to ensure stable and reliable power and signal transmission between components.

[0003] Most existing cables are crimped manually during crimping, and the efficiency of such crimping is not very high. The prior art publication number CN117477315B discloses a crimping device for automotive wiring harness cables, including a frame, a terminal fixing seat and a cable conveying plate are installed on the bottom wall of the frame, and a lower mold and an upper mold are provided on the frame that are symmetrical up and down. The present invention uses a wire arranging plate to straighten the battery core and clamp the battery core end immediately after the main cutting plate strips the cable insulation layer, and then drives the terminal fixing seat to sleeve the terminal from the bottom of the battery core on the outer periphery of the battery core, and then uses the lower mold and the upper mold to crimp the terminal and the battery core, replacing the prior art method of first stripping the insulation layer of the cable and then conveying it to the cable conveying plate for crimping, avoiding the problem of poor socketing of the terminal due to divergence of the battery core during the conveying process. The present application completes the operation of stripping the insulation layer and crimping the cable at one time, improves the efficiency of crimping, and can reduce the defects of crimping. However, when the device is in use, two wire-management plates are used to form a circular ring that is sleeved outside the battery cell and moves along the outer wall of the battery cell to straighten the battery cell. In this way, the wire-management plates are prone to damage the outer surface of the battery cell when moving along the outer wall of the battery cell. In particular, when there is an insulating layer on the outer surface of the battery cell, if the insulating layer is damaged, leakage and short circuit may occur later. Summary of the invention

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides a crimping device for automotive wiring harness cables, which can effectively solve the problem in the prior art that the wire management plate moves along the outer wall of the battery cell and causes damage to the battery cell.

The clamping head is used to clamp the terminal on the outer surface of the cable, and the flexible placement frame is used to carry the cable and adjust the inner wall diameter according to the cross-sectional diameter of the cable.

[0006] Preferably, a connecting block is fixedly installed at a position of the inner top end of the operating box away from the feed port, a baffle is fixedly installed at the lower end surface of the connecting block, a linear drive device is fixedly installed at a position of the inner top end of the operating box close to the feed port, the output end of the linear drive device is fixedly connected to two chucks, sponges are fixedly installed on opposite surfaces of the two chucks, a trigger sensor is embedded on the outer peripheral surface of the sponge close to the chuck, the trigger sensor is signal-connected with the linear drive device, two pairs of slide rails are symmetrically installed on both sides of the inner wall of the operating box, slide rods are slidably installed on the inner walls of the two pairs of slide rails, the slide rods penetrate the chucks and are slidably connected thereto, connecting rods are fixedly installed on the opposite sides of the two chucks, and push rods are fixedly installed on the lower end surfaces of the two chucks.

[0007] Preferably, external covers are symmetrically installed on both sides of the operating box, and two gas injection boxes are fixedly installed at the inner wall of the external cover away from the discharge port. A linkage rod is slidably installed on the inner wall of the two gas injection boxes. The linkage rod slider is composed of a straight rod integrally formed with one side of the slider, and the end of the straight rod away from the gas injection box is fixed to the connecting rod, and a sealing slide is fixedly installed on the side of the linkage rod close to the clamping ring. The sealing slide is air-tightly slidably connected to the gas injection box, and two gas pipes are connected to the opposite sides of the two gas injection boxes, and the two gas pipes pass through the clamping ring and are connected to the airbag.

[0008] Preferably, an upper bracket is fixedly mounted on the upper end surface of the operation box, a first driving source is fixedly mounted on the lower end surface of the upper bracket, and a driving end of the first driving source is fixed to the chuck.

[0009] Preferably, a lower bracket is fixedly installed on the lower end surface of the operating box, a second driving source is fixedly installed on the upper end surface of the lower bracket, a support plate is fixedly installed on the telescopic end of the second driving source, the upper end surface of the support plate is fixedly connected to the flexible placement frame, and a second magnet is fixedly installed on the upper end surface of the flexible placement frame.

[0011] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects: First, the outer surface of the cable is fixed by two clamps that are driven close to each other. While the clamps move to fix the cable, the air in the gas injection box can be pushed into the air bag through the air pipe by the setting of the connecting rod and the linkage rod. By the setting of the clamp ring, the air bag can only expand toward the axial center line position of the clamp ring. The expanded air bag will fix the battery cells of the cable together. At this time, the battery cells of the cable are fixed together with the outer surface of the cable, and the sponge and air bag can effectively fix the cable while avoiding movement on the outer surfaces of the cable and the battery cell, which will cause damage to the appearance of the cable and the battery cell.

[0012] Secondly, the two clamps drive the push rod to move when they move relative to each other. When the push rod moves, it drives the diameter of both ends of the flexible placement frame to decrease through the guide rod to match the diameter of the cable clamped by the two clamps. Therefore, when placing the terminal in the flexible placement frame, the matching degree of the terminal and the outer surface diameter of the cable can be effectively improved, avoiding the use of terminals that do not match the cable diameter for connection.

[0022] Reference Fig. 9 Two sliders 507 are symmetrically slidably installed in the support plate 506, and two support rods 508 are fixedly installed on the upper end surfaces of the two sliders 507. A first magnet 509 is fixedly installed on the opposite side of the two support rods 508, and the first magnet 509 is magnetically connected to the second magnet 513. At least one magnetic strip 514 is fixedly installed on the inner wall of the flexible placement frame 512, and two external blocks 510 are symmetrically installed on the lower end surface of the support plate 506. A spring 511 is fixedly installed on the side of the two external blocks 510 close to the slider 507, and the two ends of the spring 511 are respectively connected to the slider 507 and the external block 510. A guide rod 515 is fixedly installed on the opposite side of the two support rods 508, which are driven to move toward each other by the support rods 508, so that the second magnet 513 can drive the flexible placement frame 512 to relatively reel up, thereby reducing the diameter of the flexible placement frame 512.

[0023] The working principle of the present invention is as follows: The prepared cable is placed thereon, and the battery core passes through the two clamps 304 and the airbag 407 and rests against the baffle 302, being restricted from continuing to extend toward the interior of the operating box 2. The linear drive device 303 is started, and the driving end of the linear drive device 303 drives the two clamps 304 to clamp. When the two clamps 304 move toward each other to clamp, the sponge 306 contacts the cable first. The sponge 306 can protect the outer surface of the cable. During the continuous clamping process of the clamps 304, cables of different diameters are fixed between the two clamps 304, and the trigger sensor 305 is triggered. The trigger sensor is a device that detects and responds to specific events. It can detect the approach or touch of an object, thereby starting or stopping the device. The triggered trigger sensor 305 sends a signal to the linear drive device 303 to stop driving the two clamps 304 to move continuously. When the two clamps 304 are driven to move, the connecting rod 307 is driven to move, and the connecting rod 307 is driven to move during the movement. The linkage rod 402 drives the sealing slide plate 404 to slide airtightly on the outer wall of the gas injection box 403 during the sliding process to prevent air loss. The linkage rod 402 compresses the air inside the gas injection box 403 during the movement, and the compressed air enters the airbag 407 through the air delivery pipe 405 to expand the airbag 407. During the expansion process, the airbag 407 will only expand toward the axial center line of the airbag 407 due to the setting of the clamp ring 406, so as to fix the battery core of the cable and gather the loose battery cores together. The two chucks 304 driven to move relative to each other will drive the push rod 310 to move relative to each other when moving, and the push rod 310 will drive the linkage rod 402 to move relative to each other when moving relative to each other, and the linkage rod 402 will drive the support rod 508 to move relative to each other when moving relative to each other, and the support rod 508 will stably move in the support plate 506 through the setting of the slider 507 during the relative movement, and the slider 507 will compress the spring 511 with the external block 510 during the sliding process, and the support rod 508 will drive the second magnet 513 to move relative to each other through the magnetic connection between the first magnet 509 and the second magnet 513 during the relative movement, and the second magnet 513 will reduce the distance between the two ends of the flexible placement frame 512 during the relative movement, so that the diameter between the two ends of the flexible placement frame 512 is reduced; It should be noted that, in the process of relative movement between the two clamps 304 to clamp the cable, cables of different diameters will trigger the sensor 305 when being clamped by the clamp 304, and send a signal to stop the linear drive device 303 from moving by triggering the sensor 305, so that when the clamp 304 clamps cables of different diameters, the push rod 310 will drive the guide rod 515 to move relatively, and the guide rod 515 will drive the second magnet 513 and the flexible placement frame 512 to move relatively through the support rod 508 and the first magnet 509, and then the two ends of the flexible placement frame 512 will reduce in diameter. After the diameter of the flexible placement frame 512 is reduced, the diameter of the flexible placement frame 512 will be equal to the diameter of the cable, so as to facilitate the placement of terminals with the same diameter as the cable inside the flexible placement frame 512, so as to avoid employees placing mismatched terminals, resulting in defective products in subsequent crimping and waste; After determining the diameter of the terminal to be placed, the matching terminal is placed in the flexible placement frame 512, and the flexible placement frame 512 for placing the terminal is driven to rise by turning on the second driving source 505. It should be noted that in the process of placing the terminal, the terminal has an opening, and the opening needs to be placed upward to ensure that the battery cell can be placed normally inside the terminal. After the flexible placement frame 512 drives the terminal to rise, the guide rod 515 will always be slidably connected with the push rod 310 to keep the two ends of the flexible placement frame 512 matched with the terminal diameter to prevent the terminal from rotating therebetween. After the rising terminal is connected to the battery cell, the first driving source 502 is started to drive the clamping head 503 to descend. The clamping head 503 will contact the opening of the terminal during the descent process and squeeze the opening of the terminal to make the opening roll back to the position of the battery cell, thereby fixing the terminal and the battery cell. After the terminal and the battery cell are fixed, the two clamps 304 can be separated by opening the linear drive device 303. The two separated clamps 304 will drive the linkage rod 402 to slide back to the original position in the inner wall of the gas injection box 403 through the connecting rod 307, and the air inside the airbag 407 will be re-exhausted into the interior of the gas injection box 403. The airbag 407 will retract to release the fixed battery cell, and by driving the first driving source 502 and the second driving source 505 back to the original position, the terminal will be fixed on the outer surface of the battery cell.
