Technical Field

[0001] The present invention relates to the technical field of automotive parts processing, and particularly to a wire threading and assembling mechanism for automotive wire harness terminals and terminal housings. Background Art

[0002] Automotive wire harness terminals are crucial conductive components in the automotive wire harness system, mainly responsible for electrical connection tasks to ensure the current and signal transmission between various electrical devices in the vehicle. The automotive wire harness terminal housing is used to fix the wire harness terminal in a specific position, prevent it from shifting or falling off due to vibration and shaking during vehicle driving, protect the terminal from the external environment, and ensure insulation between terminals and between the terminal and the vehicle body or other components, prevent current leakage, and improve the safety and reliability of the electrical system. The wire threading of automotive wire harness terminals and terminal housings is a key process in wire harness assembly, directly affecting the electrical performance and reliability of the wire harness.

[0003] In the existing wire threading work of automotive wire harness terminals and terminal housings, only the material taking part is automated, and the wire threading process requires manual operation by workers. However, manual wire threading has low efficiency and uneven quality.

[0004] Therefore, a wire threading and assembling mechanism for automotive wire harness terminals and terminal housings is proposed to make the wire threading process fully automated and improve the wire threading efficiency and quality. Summary of the Invention

[0005] In view of the above problems that only the material taking part is automated in the existing wire threading work of automotive wire harness terminals and terminal housings, and the wire threading process requires manual operation by workers, but manual wire threading has low efficiency and uneven quality, the present invention is proposed.

[0006] To solve the above technical problems, the present invention provides the following technical solution: A wire threading and assembling mechanism for automotive wire harness terminals and terminal housings, which includes a machine body, a feeding tray, and a turntable shaft for driving the feeding tray to rotate. A material taking mechanism and a wire threading mechanism are arranged on the machine body. The wire threading mechanism includes a large module, a small module, and a wire drawing mechanism; The large module includes a fixing plate fixed on the machine body. A fixing column is fixedly arranged on the top of the fixing plate. A fixing vertical plate is fixedly arranged on the side of the fixing column. A wire threading guide rail A is arranged on the fixing vertical plate. A wire threading lead screw A is arranged in the wire threading guide rail A. One end of the wire threading guide rail A is connected to a motor B. The output shaft of the motor B is connected to the wire threading lead screw. A wire threading slider A is arranged on the wire threading lead screw A. A rotary clamping cylinder B and a vertical cylinder A are arranged on the side of the wire threading slider A away from the feeding tray. The cylinder body of the rotary clamping cylinder B is arranged at the output end of the vertical cylinder A. The rotary clamping cylinder B is horizontally arranged, and the jaws of the rotary clamping cylinder B face the material taking mechanism; The small module includes a threading guide rail B disposed on a fixed vertical plate on the side away from the loading tray. A threading lead screw B is arranged inside the threading guide rail B. A threading slider B is arranged on the threading lead screw B. A side plate B is arranged on the threading slider B. The side plate B is arranged perpendicular to the axis direction of the threading lead screw B. An up-and-down cylinder B is arranged on the side plate B. The output end of the up-and-down cylinder is provided with a wire-straightening cylinder, and the jaws of the wire-straightening cylinder face downward.

[0007] By adopting the above solutions, the automatic material taking and automatic threading processes are realized, improving work efficiency and processing quality. The material taking mechanism grabs the wire harness terminals on the loading tray and then transports them to the set position. Then the large module moves to the position of the wire harness terminals, and the rotary clamping cylinder B grabs the wire harness terminals. Then the large module moves backward to drive the wire harness terminals into the terminal housing. During this process, the small module straightens the wire harness on the wire harness terminals, making it more convenient to thread the wire harness into the terminal housing.

[0008] Preferably, the wire-drawing mechanism includes a threading lead screw C arranged on the side of the fixed vertical plate away from the loading tray. A threading slider C is arranged on the threading lead screw C. A side plate C is arranged on the side of the threading slider C away from the loading tray. A connecting plate is arranged on the side of the side plate C away from the rotary clamping cylinder B. A wire-drawing cylinder is fixedly arranged at the bottom of the connecting plate, and the jaws of the wire-drawing cylinder face the rotary clamping cylinder B.

[0009] By adopting the above solutions, after the wire harness terminals are completely inserted into the terminal housing, the wire-drawing cylinder is moved to the front of the terminal housing through the transmission of the threading lead screw. Then the wire-drawing cylinder cooperates with the rotary clamping cylinder B to complete the installation of the terminal housing and the terminal completely.

[0010] Preferably, the wire-drawing mechanism further includes a threading track arranged above the threading lead screw C. The threading track is fixed on the side plate C.

A belt is connected in a matching manner between the driving pulley and the driven pulley.

[0011] By adopting the above solutions, the wire-drawing mechanism is transported to the front of the terminal housing to realize the position adjustment of the wire-drawing mechanism.

[0014] Preferably, the material taking mechanism includes a material taking guide rail fixedly arranged on the top of the machine body. A material taking lead screw is arranged in the material taking guide rail. A material taking slider is arranged on the material taking lead screw.

A motor A is arranged on one side of the material taking guide rail close to the loading tray. The output shaft of the motor A is connected to the material taking lead screw.

[0015] By adopting the above scheme, automatic material taking from the loading tray is realized, and the working efficiency is improved. The motor A drives the material taking lead screw to transport the rotary clamping cylinder A to the position of the loading tray. After the rotary clamping cylinder A grabs the wire harness terminal, the material taking lead screw transports the rotary clamping cylinder A to the wire threading position, realizing the automatic material taking process.

[0016] Preferably, a wire rail connecting plate A is arranged on the top of the slider support plate. A wire rail for installing the power transmission line is arranged on the wire rail connecting plate A.

[0018] The beneficial effects of the present invention are as follows: 1. By setting the material taking mechanism, the automatic material taking process is realized, and the working efficiency of the device is improved. The motor A drives the material taking lead screw to move, transports the rotary clamping cylinder A to the position of the loading tray, then grabs the wire harness terminal, and then the motor A reverses, and transports the rotary clamping cylinder A to the wire threading position through the material taking lead screw.

[0019] 2. By setting the large module and the wire drawing mechanism, the automatic wire threading and installation work of the wire harness terminal and the terminal shell is realized, improving the wire threading efficiency and wire threading quality. The rotary clamping cylinder B on the large module moves to the rotary clamping cylinder A to take materials.

[0046] Working principle: Feeding process: The motor A408 works to drive the feeding lead screw 402 to rotate, and then the side plate is transported to the feeding tray 2. Then the feeding cylinder 409 pushes out to lift the rotary clamping cylinder A. After the rotary clamping cylinder A406 grabs the wire harness terminal 52, the motor A408 rotates in reverse, and the feeding lead screw 402 transports the rotary clamping cylinder A406 to the wire threading position. Then the clamping jaws of the rotary clamping cylinder A406 rotate a certain angle, generally 90 degrees, to thread the wire harness 53 parallel to the wire threading guide rail A304 to cooperate with wire threading. It should be noted that the feeding cylinder 409 does not need to retract after reaching the wire threading position.

[0047] Threading process: The operation of motor B306 drives the rotation of threading lead screw A305, thereby moving threading slider A307. Threading slider A307 transports rotary clamping cylinder B308 and wire-straightening cylinder 605 to the threading position. Upper and lower cylinder A310 and upper and lower cylinder B608 descend simultaneously. Rotary clamping cylinder A406 clamps the wire harness terminal 52. Wire-straightening cylinder 605 enters the wire-straightening position. The jaws of wire-straightening cylinder 605 clamp the wire harness 53, straightening the loose wire harness 53 and straightening it to the required position. Then rotary clamping cylinder A406 releases. Upper and lower cylinder A310 and upper and lower cylinder B608 rise simultaneously. At the same time, the vibrating disk feeding mechanism places the terminal housing 51 at the assembly position.

[0048] Threading lead screw A305 transports the wire harness terminal 52 to a position before the threading position. Upper and lower cylinder A310 and upper and lower cylinder B608 descend simultaneously. Upper and lower cylinder C708 descends, and places the guide rod 709 into the terminal housing 51. Threading lead screw A305 continues to move, and sends the front end of the wire harness terminal 52 into the terminal housing 51 to about 10 mm. The wire-straightening jaws release. Upper and lower cylinder B608 rises. Threading lead screw B602 runs to the safe position.

[0049] Threading lead screw A305 continues to insert the wire harness terminal 52 into about 20 mm. Then upper and lower cylinder C708 drives the guide rod 709 to rise. Then the wire-pulling cylinder 707 clamps the wire harness terminal 52. Threading lead screw A305 runs the wire harness terminal 52 to the required position in the terminal housing 51. Then the jaws of rotary clamping cylinder B308 and the jaws of wire-pulling cylinder 707 release simultaneously, completing the assembly process of the wire harness terminal 52 and the terminal housing 51.
