[0001] This invention relates to the field of automotive wiring harness terminal crimping mold technology, specifically a dual-station crimping mold. Background Technology

[0002] With the current trend of automotive intelligence, the penetration rate of ADAS (Advanced Driver Assistance Systems) is rapidly increasing, the number of on-board sensors is increasing, and the data transmission requirements (high-speed, high-frequency, large data volume) are correspondingly increasing. As a result, the usage of on-board radio frequency connectors is also growing. FAKRA connectors are a common standard radio frequency signal connector in the automotive industry and are now widely used in the industry. This places higher demands on the processing efficiency of equipment. Currently, the industry's processing equipment can only process a single terminal at a time, which results in low efficiency. Therefore, there is an urgent need for a high-efficiency automated processing equipment. Summary of the Invention

[0038] The feeding base plate assembly 3 includes a feeding base plate 301. Parallel A slide rail 315 and B slide rail 316 are arranged on the feeding base plate 301. An A-claw guide plate 306 and a movable A-pressure plate 311 are provided at the A slide rail 315. A B-claw guide plate 304 and a movable B-pressure plate 314 are provided at the B slide rail 316. The A-terminal positioning plate 302, B-terminal positioning plate 303, B-claw guide plate 304, A-claw guide plate 306, and baffle 307 are fixed to the feeding base plate 301 by bolts. The A-claw guide plate 306 and baffle 307 are fixed by threads. The A-pressure plate 311 is positioned by a slotted fit with the feeding base plate 301. The B-pressure plate 314 is positioned by a slotted fit with the feeding base plate 301. The square hole on the material base plate 301 is used for positioning. The outer circumference of the cam 313 is tangent to the inner circumference of the hole in the B pressure plate 314 to form a cam engagement. The inner circumference of the pressure handle 310 is tangent to the inner circumference of the hole in the A pressure plate 311 to form a cam engagement. The flat pin 309 is connected to the flat square hole of the pressure handle 310 and the cam 313 to form a transmission engagement. The flat pin 309 is connected to the round hole of the feeding base plate 301 to form a hinge. The four clamping screws 308 are connected to the threads of the A pressure plate 311 and the B pressure plate 314 respectively. One end of the four springs 312 is inserted into the clamping screws 308, and the other end is inserted into the four countersunk holes under the feeding base plate 301. The adjusting screw 305 is connected to the clearance of the hole in the feeding base plate 301.

[0039] The feeding assembly 4 includes a mounting plate 403, which is connected to a mounting base 112 on the main body assembly 1. A slide rail 404 is provided on the mounting plate 403, and a moving block 412 is slidably connected to the slide rail 404. The bottom end of the moving block 412 is provided with a movable feeding claw A 409 and a feeding claw B 408, with the feeding claw B 408 located between the feeding claw A 409 and the mounting plate 403. The component driving the feeding assembly 4 is a driving cylinder 401, which is fixedly connected to a cylinder support 402 by bolts. The cylinder support 402 is then fixedly connected to the mounting plate 403 by bolts. The rail 404 and the stop block 405 are fixedly connected to the mounting plate 403 by bolts. The A feeding claw seat 410, the B feeding claw seat 406 and the moving block 412 are hinged by the pin 411. Two torsion springs 407 are inserted into the pin 411. The B feeding claw 408 and the A feeding claw 409 are fixedly connected to the B feeding claw seat 406 and the A feeding claw seat 410 by bolts, respectively. The internal threads of the two push rods 413 are fixedly connected to the external threads of the rods of the A cylinder 414 and the B cylinder 415 by threads, respectively. Then, the A cylinder 414 and the B cylinder 415 are fixedly connected to the moving block 412 by threads, and the moving block 412 is fixedly connected to the guide block on the slide rail 404 by bolts.

[0040] In the above structure, cylinder A 414 controls the A feeding claw 409 to drop and press the terminal strip on slide A 315, thereby allowing the feeding of the terminal strip on slide A 315. At this time, cylinder B 415 controls the B feeding claw 408 to lift, thereby prohibiting the feeding of the terminal strip on slide B 316. Cylinder B 415 controls the B feeding claw 408 to drop and press the terminal strip on slide B 316, thereby allowing the feeding of the terminal strip on slide B 316. At this time, cylinder A 414 controls the A feeding claw 409 to lift, thereby prohibiting the feeding of the terminal strip on slide A 315.

[0041] The lower jaw 105 on the main body assembly 1 is adapted to the upper jaw 205 on the slider assembly 2, and the lower jaw 109 on the upper jaw 208 is adapted to the lower jaw. When the slider assembly 2 moves downward, the bottom surface of the upper punch A 209 contacts the top surface of the cutter A 113, and the bottom surface of the upper punch B 206 contacts the top surface of the cutter B 106, thereby completing the crimping of the two terminals.

[0042] The A-claw guide plate 306 is provided with an A-guide hole 317. When the drive cylinder 401 drives the terminal strip on the A slide 315 of the feeding base plate assembly 3 and moves it towards the main body assembly 1, the claw head of the A-feeding claw 409 falls down and presses against the surface of the terminal strip on the A slide 315, and moves linearly in the A-guide hole 317. The B-claw guide plate 304 is provided with a B-guide hole 318. When the drive cylinder 401 drives the terminal strip on the B slide 316 of the feeding base plate assembly 3 and moves it towards the main body assembly 1, the claw head of the B-feeding claw 408 falls down and presses against the surface of the terminal strip on the B slide 316, and moves linearly in the B-guide hole 318.

[0043] In practical use, rotating the pressure handle 310 drives the cam 313 to rotate, causing the A pressure plate 311 and the B pressure plate 314 to move upward, thus creating a space between them and the feeding base plate 301 for placing the terminal strip. The terminal strip is placed on the A slide rail 315 and the B slide rail 316 respectively. Rotating the pressure handle 310 again causes the A pressure plate 311 and the B pressure plate 314 to move downward, thereby pressing down the terminal strip.

[0044] During the terminal feeding process, cylinder B 415 is activated, and the output shaft of cylinder B 415 retracts, pulling the push rod 413 to move away from the main component 1. The feeding claw seat 406 of B rotates along the pin shaft 411, thereby causing the feeding claw 408 of B to press down on the terminal strip on the slide rail 316. At this time, the feeding claw 409 of A is in an upward state. Simultaneously, the drive cylinder 401 is activated, and the output end of the drive cylinder 401 pushes the moving block 412 to move along the slide rail 404 towards the main component 1, thereby pushing the feeding claw seat 410 of A and the feeding claw seat 406 of B to move, thereby causing the terminal strip pressed down by the feeding claw 408 of B to move.

[0045] When the terminal strip on slide rail 316 moves to lower jaw 105, a wire is placed at lower jaw 105. The hanging head 201 of slider assembly 2 is activated, starting the terminal crimping process. This causes slider 204 to move downward, thereby causing upper jaw 205 and upper punch B206 to move downward, and then lower jaw 105 to contact upper jaw 205. The bottom surface of upper punch B206 contacts the top surface of cutter B106, completing the crimping of the terminal and wire on slide rail 316.

[0046] After the terminal on slide B 316 is fed and crimped, the hanging head 201 controls the small upper jaw 205 and the upper punch B206 to move upward, while the output shaft of the drive cylinder 401 pulls the moving block 412 backward, moving the B feeding claw 408 and the A feeding claw 409 to the next terminal to be crimped.

[0047] The output shaft of cylinder B 415 extends, controlling the B feeding claw 408 to lift upwards and release the terminal strip. Cylinder A 414 is activated, and the output shaft of cylinder A 414 retracts, pulling the push rod 413 to move away from the main component 1. The A feeding claw seat 410 rotates along the pin 411, thereby causing the A feeding claw 409 to press down on the terminal strip on the A slide rail 315. The drive cylinder 401 is activated, and the output shaft of the drive cylinder 401 pushes the moving block 412 to move along the slide rail 404 towards the main component 1, thereby pushing the A feeding claw seat 410 and the B feeding claw seat 406 to move, thereby causing the terminal strip on the A slide rail 315 pressed down by the A feeding claw 409 to move.

[0048] When the terminal strip of slide rail 315 moves to lower jaw 109, a wire is placed at lower jaw 109. The hanging head 201 of slider assembly 2 is activated, starting the terminal crimping process. This causes slider 204 to move downward, thereby causing upper jaw 208 and upper punch A 209 to move downward, and then lower jaw 109 to contact upper jaw 208. The bottom surface of upper punch A 209 contacts the top surface of cutter A 113, completing the crimping of the terminal and wire on slide rail 315.

[0049] After the terminal on slide A 315 is fed and crimped, the hanging head 201 controls the upper jaw 208 and the upper punch A 209 to move upward, while the output shaft of the drive cylinder 401 pulls the moving block 412 backward, moving the B feeding claw 408 and the A feeding claw 409 to the next terminal to be crimped.

[0050] Then, the alternating feeding and crimping process of the terminal strips on slide A 315 and slide B 316 is repeated.

[0051] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. The scope of patent protection of the present invention shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present invention shall also be included within the scope of protection of the present invention.
