Description

Technical Field

[0001] This invention relates to the field of wire harness terminal plugging, specifically a wire harness terminal plugging device. Background Technology

[0002] New energy vehicle wiring harness terminals are electrical connectors used to connect and fix new energy vehicle wiring harnesses. Wiring harness terminals are important components used to transmit power, signal, and data, and are used to connect different electronic devices, sensors, and controllers. The connection between new energy vehicle wiring harnesses is completed by plugging in the female terminal and the male terminal together. Generally, wiring harness terminal plugging devices are needed to carry out a large number of terminal plugging tasks.

[0003] However, the existing wire harness terminal plugging devices do not have high synchronization in placing the female and male terminals in the plugging position, resulting in a terminal pairing time difference. In addition, the feeding fixture has a single structural form, and generally the plugging is performed after the feeding fixture is completed or the feeding fixture is performed after the plugging is completed, which is not conducive to improving the overall processing efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a wire harness terminal plug-in device in order to solve the above-mentioned problems.

[0005] The present invention achieves the above-mentioned objective through the following technical solution: a wire harness terminal plugging device, comprising a terminal tooling mechanism, two turntables for assembling female and male terminals, a T-shaped plate, a terminal stacking tube, a first cylinder, a second cylinder, and a vibration motor. Each turntable has multiple right-angle slots distributed on its surface, and a terminal tooling mechanism is configured at each right-angle slot. One end of a strip hole communicating with one end face of the T-shaped plate is rotatably connected to a drive shaft located in the middle of the turntable. The two T-shaped plates move in opposite directions to form a plugging force on the same pair of female and male terminals. The terminal tooling mechanism includes a carrier, a J-shaped clamp, a bar magnet, and a bar electromagnet. A rectangular slot is provided on the top of the carrier, and one end of the J-shaped clamp is installed at both sides of the slot opening. Two bar electromagnets in the same group are respectively installed on the side walls of the rectangular slot, and the bar electromagnets and the bar magnet located on the other side wall of the J-shaped clamp form a magnetic field force. A vibration motor is installed on one side of the terminal stacking tube, and the top of the rectangular hole located at the bottom side of the terminal stacking tube is rotatably connected to one end of the rectangular baffle through a rotating shaft fitted with a torsion spring. An L-shaped insert bracket located on one side of the bottom port of the terminal stacking tube forms a terminal support structure with the rectangular baffle, and the horizontal end of the L-shaped insert bracket is inserted between two J-shaped clips in the same group by movement.

[0006] Preferably, the bottom of the carrier is fixed to two short guide rails by adjustment, and the two short guide rails are fixedly installed alternately on the side walls of the right-angle slots.

[0007] Preferably, the two ends of the drive shaft in the middle of the turntable are located in corresponding circular grooves, and a servo motor and an electromagnetic brake are respectively installed in the two circular grooves of the same group.

[0008] Preferably, the bottom sides of the T-shaped plate are equipped with sliding blocks, and the two sliding blocks are slidably connected to two long guide rails respectively. The two long guide rails are fixedly installed in parallel on the platform, and the platform has a slotted hole structure in the middle.

[0009] Preferably, a vertical plate is fixedly installed on one side of the top of the T-shaped plate, and a guide plate is fixedly installed at the output end of the first cylinder at the top of the vertical plate. The guide plate is fixedly connected to one end of the strip plate by positioning bolts, and the other end of the strip plate is fixedly connected to the side wall of the vibration motor.

[0010] Preferably, the two protrusions at the bottom of the T-shaped plate are respectively connected to the output ends of the two second cylinders.

[0011] Preferably, one end of the rectangular hole is connected to the port face corresponding to the bottom end of the terminal stacking tube, and the bottom end face of the rectangular baffle located at the rectangular hole is higher than the top end face of the J-shaped clip standing at the highest point.

[0012] Preferably, the internal structure shape of the terminal stacking tube matches the corresponding surrounding structure shape of the placed terminal.

[0013] The beneficial effects of the present invention are: 1. By distributing and installing the terminal tooling mechanism in each right-angle slot on the turntable, and combining the synchronous counter-rotation of the two turntables, the assembly speed between the female and male terminals to be inserted is accelerated. At the same time, the magnetic pole change of the magnetic field generated by the bar electromagnet is used to repel and clamp the terminal or magnetically attract and release the terminal clamping on the bar magnet located on the other side wall of the J-type clip. The terminal feeding tooling and insertion can be completed simultaneously, which greatly improves the insertion efficiency of the wire harness terminal. 2. A long tube for stacking terminals with a high degree of matching between its internal structure shape and the corresponding terminal surface structure shape is used, and a vibration motor is used to control the vibration of the long tube for stacking terminals. At the same time, the L-shaped bracket and the rectangular baffle form a terminal dropping structure, which can stack several terminals together from bottom to top and ensure that they fall into the terminal dropping structure in an orderly manner. Third, by using the first cylinder as a horizontal pushing force structure, the terminals at the terminal support structure can be delivered between the two J-shaped clamps, solving the problem of inconvenient material feeding and conveying tooling due to the small size of the terminals.

[0020] Please see Figure 1-5 As shown, a wire harness terminal plugging device includes a terminal tooling mechanism 1, two turntables 2 for assembling female and male terminals, a T-shaped plate 3, a terminal stacking tube 4, a first cylinder 5, a second cylinder 8, and a vibration motor 11. Each turntable 2 has multiple right-angle slots 210 distributed on its surface, and a terminal tooling mechanism 1 is arranged at each right-angle slot 210. One end of the strip hole 310 communicating with one end face of the T-shaped plate 3 is rotatably connected to the drive shaft located in the middle of the turntable 2. The two T-shaped plates 3 move in opposite directions to form a plugging force on the same pair of female and male terminals. The terminal tooling mechanism 1 includes a carrier 120, a J-shaped clamp 130, a bar magnet 131, and a bar electromagnet 140. The top of the carrier 120 has a rectangular groove 121, and one end of the J-shaped clamp 130 is installed at both sides of the groove opening. Two bar electromagnets 140 of the same group are respectively installed on the two side walls inside the rectangular groove 121, and the bar electromagnets 140 and the bar magnet 131 located on the other side wall of the J-shaped clamp 130 form a magnetic field force. Combination Figure 1 , Figure 2 and Figure 5 As shown, by distributing the terminal tooling mechanism 1 to each right-angle slot 210 distributed on the turntable 2, and combining the synchronous opposite rotation of the two turntables 2, the assembly speed between the female and male terminals to be inserted is accelerated. At the same time, the magnetic pole change of the magnetic field generated by the bar electromagnet 140 is used to repel and clamp the terminal or magnetically attract and release the terminal clamping on the bar magnet 131 located on the other side wall of the J-type clip 130, which greatly improves the insertion efficiency of the wire harness terminal.

[0021] A vibration motor 11 is installed on one side of the terminal stacking tube 4, and the top end of the rectangular hole 410 located on the side of the bottom end of the terminal stacking tube 4 is rotatably connected to one end of the rectangular baffle 420 through a rotating shaft fitted with a torsion spring. The L-shaped insert bracket 430 located on one side of the bottom port of the terminal stacking tube 4 and the rectangular baffle 420 form a terminal support structure. The horizontal end of the L-shaped insert bracket 430 is inserted between two J-shaped clips 130 in the same group by movement. One end of the rectangular hole 410 is connected to the port surface corresponding to the bottom end of the terminal stacking tube 4, and the bottom end face of the rectangular baffle 420 located at the rectangular hole 410 is higher than the top end face of the J-shaped clip 130 standing at the highest point. The internal structure shape of the terminal stacking tube 4 matches the corresponding surrounding structure shape of the placed terminal. Combination Figure 2 and Figure 4As shown, a terminal stacking tube 4 with a high degree of matching between its internal structure shape and the corresponding terminal surface structure shape is used, and a vibration motor 11 is used to control the vibration of the terminal stacking tube 4. At the same time, the L-shaped insertion bracket 430 and the rectangular baffle 420 form a terminal dropping structure, which can stack several terminals together from bottom to top and ensure that they fall into the terminal dropping structure in an orderly manner. The first cylinder 5 serves as a horizontal pushing force structure, which can send the terminals at the terminal dropping structure to the two J-shaped clamps 130, thus solving the problem of inconvenient material feeding and conveying tooling due to the small size of the terminals.

[0022] like Figure 5 As shown, the bottom of the carrier 120 is fixed to two short guide rails 110 by adjustment, and the two short guide rails 110 are fixedly installed alternately on the side wall of the right angle groove 210 so as to adjust the position of the carrier 120.

[0023] The two ends of the drive shaft in the middle of the turntable 2 are respectively located in the corresponding circular grooves 311. A servo motor and an electromagnetic brake are respectively installed in the two circular grooves 311 of the same group. The servo motor and the electromagnetic brake can complete the rotation and fixation of the turntable 2.

[0024] like Figure 3 As shown, slide blocks 320 are installed on both sides of the bottom of the T-shaped plate 3, and the two slide blocks 320 are slidably connected to two long guide rails 10 respectively. The two long guide rails 10 are fixedly installed in parallel on the platform 9, and the platform 9 has a slotted hole structure in the middle. The stability of the T-shaped plate 3 in moving and guiding is ensured by the long guide rails 10.

[0025] Furthermore, a vertical plate 330 is fixedly installed on one side of the top of the T-shaped plate 3, and a guide plate 6 is fixedly installed at the output end of the first cylinder 5 located at the top of the vertical plate 330. The guide plate 6 is fixedly connected to one end of the strip plate 7 by positioning bolts, and the other end of the strip plate 7 is fixedly connected to the side wall of the vibration motor 11.

[0026] Furthermore, the two protrusions at the bottom of the T-shaped plate 3 are respectively connected to the output ends of the two second cylinders 8.

[0027] Working principle: The first cylinder 5 moves the bottom end of the terminal stacking tube 4, which is connected by the guide plate 6, the strip plate 7 and the vibration motor 11, towards the terminal tooling mechanism 1, which is in a vertical position directly in front of it, until the part of the terminal located between the bottom end of the L-shaped bracket 430 and the rectangular baffle 420 is delivered between the two J-shaped clamps 130 in the same group. At this time, the outer side of the energized bar electromagnet 140 forms the same magnetic pole that repels the bar magnet 131, causing the corresponding part of the J-shaped clamp 130 to extend outward, which plays the role of clamping and fixing the terminal. After the terminal is clamped and fixed, the first cylinder 5 retracts and resets, and the rectangular baffle 420 unfolds outward so that the remaining part of the terminal is completely separated from the terminal stacking tube 4, while providing a space for the next terminal to slide down. While the terminal stacking tube 4 is reset, the two second cylinders 8 extend synchronously to move the T-shaped plates 3 connected to them toward the center of the platform 9, and in conjunction with the synchronously running servo motor, rotate the connected turntable 2, so that the mother and child terminals that have been fixed by the tooling are in a horizontal state. Due to multiple equipment calibrations and the fact that the important connection parts of the mother and child terminals exceed the rectangular slot 121, the insertion task between the mother terminal and the child terminal can be completed. At the same time, under the action of the first cylinder 5 that extends again, the terminal tooling mechanism 1 at another location also completes the terminal loading tooling. After the insertion is completed, the bar electromagnet 140 changes the direction of the current to change the magnetic poles and magnetically attracts the corresponding part of the previously repelled J-type clip 130 and moves it inward, releasing the fixed restraint on the inserted female and male terminals, and resetting the whole assembly to prepare for the insertion of the next task.
