In the prior art, personnel generally manually insert the wire harness with terminals into the corresponding connector on a work surface to achieve assembly.

[0003] Authorization announcement No. CN215184979U discloses a precise guiding auxiliary device for assembling wiring harness terminals and connectors.

[0015] Step 2: Before stacking the low-voltage connecting wires, first retract the telescopic ends of the two comb plates through the controller to move each barrier plate away from the storage plate, and then stack each required low-voltage connecting wire in an up-and-down manner and place them into each storage slot in turn. Then, control the telescopic ends of the comb plates to extend horizontally to reset each barrier plate.

DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with the embodiments.

[0026] Embodiment 1: Figures 1 to 5 As shown, an automobile low-voltage wiring harness assembly device includes an assembly platform 1, a positioning plate 11 is fixedly arranged on the upper surface of the assembly platform 1, a connector 111 is horizontally placed on the positioning plate 11, the size of the positioning plate 11 is adapted to the connector 111, and the connector 111 can be ensured to be just embedded in the positioning plate 11, and a plurality of low-voltage connecting wires 112 are also arranged on the assembly platform 1, and a plurality of jacks are evenly arranged on the connector 111, and the low-voltage connecting wire 112 is composed of a wiring harness and a terminal connected to one end of the wiring harness, and the connector 111 and the low-voltage connecting wire 112 are both components of the automobile low-voltage wiring harness in the prior art, wherein the terminal can be horizontally inserted into the jack, so as to realize the assembly of the low-voltage connecting wire 112 and the connector 111. A controller 12 is fixedly installed on the upper surface of the assembly platform 1.

[0027] The upper surface of the assembly table 1 is provided with an automatic assembly mechanism, which includes two wall groove plates 21 fixedly connected to the upper surface of the assembly table 1. The two wall groove plates 21 are both located on the side of the connector 111 close to the jack. The two wall groove plates 21 are slidably provided with a slider plate 22 on the side close to each other. The two wall groove plates 21 are respectively provided with a limit groove on the side close to each other. The slider plate 22 is slidably connected in the limit groove, and the slider plate 22 can only move horizontally along the track of the limit groove. The two slider plates 22 are fixedly connected with a placement plate 23 on the side close to each other. The placement plate 23 is provided with a receiving groove 24 corresponding to the position of the jack. The shape of the receiving groove 24 is adapted to the shape of the terminal in the low-voltage connecting line 112, that is, the terminal can be placed in the receiving groove 24 from top to bottom, and initially, a terminal is placed inside each receiving groove 24, and only one terminal is shown in the figure. The placement plate 23 is provided with a U-shaped opening 25 at a position corresponding to each receiving groove 24. A small motor 26 is fixedly installed on the upper surface of the assembly platform 1, and the small motor 26 is controlled by the above-mentioned controller 12. A screw rod 27 is fixedly connected to the output shaft of the small motor 26, and the screw rod 27 is located between the two wall groove plates 21. The end of the screw rod 27 away from the small motor 26 is rotatably connected to the upper surface of the assembly platform 1. A nut sleeve block 28 is threadedly connected to the screw rod 27, and the initial positions of the placement plate 23 and the nut sleeve block 28 are both located at a position close to one side of the small motor 26. A connecting plate 29 is fixedly connected between the top surface of the nut sleeve block 28 and the bottom surface of the placement plate 23. After the placement plate 23 is horizontally displaced to the final position in the direction close to the connector 111, the side surface of the placement plate 23 close to the connector 111 can be horizontally fitted with the outer surface of the connector 111. Specifically, after the placement plate 23 moves to the final position, the terminal placed in the receiving groove 24 can be just inserted into the corresponding jack.

[0028] When in use: the staff first places a connector 111 horizontally on the positioning plate 11, and ensures that the various jacks on the connector 111 face the various placement plates 23. The positioning plate 11 can ensure that the various jacks of the connector 111 are aligned with the receiving slots 24, and then the small motor 26 is started by the controller 12. After the small motor 26 is started, the output shaft drives the screw rod 27 to rotate forward. As the screw rod 27 rotates forward, under the limiting action of the limiting groove in the wall slot plate 21 and the slider plate 22, the nut sleeve block 28 and the placement plate 23 will be driven to gradually translate in the direction close to the connector 111, thereby driving the various low-voltage connecting wires 112 placed inside the receiving slot 24 to move synchronously until each terminal is inserted into the corresponding jack at the same time. At this point, the assembly of a connector 111 and various low-voltage connecting wires 112 is completed. After a connector 111 and each low-voltage connecting wire 112 are assembled, the positions of the connector 111 and the low-voltage connecting wire 112 are both located on the side close to the positioning plate 11, and then the staff manually takes the connector 111 upward from the positioning plate 11, and at the same time, the terminals in the low-voltage connecting wire 112 that have been assembled with the connector 111 are also moved upward away from the inside of the receiving groove 24. During the process, the wiring harness in the low-voltage connecting wire 112 will move up from the U-shaped mouth 25, and as the staff takes away the connector 111 and the low-voltage connecting wire 112, the wiring harness will pass through the U-shaped mouth 25 and the receiving groove 24, so that the assembled connector 111 and the low-voltage connecting wire 112 can be taken away. Subsequently, the next connector 111 is placed horizontally on the positioning plate 11 for subsequent assembly.

[0029] Therefore, by cooperating with the provided placement plate 23, the accommodating groove 24, the small motor 26 and other components, the terminals of each low-voltage connecting line 112 can be automatically plugged into all the sockets on a connector 111 at one time, thereby realizing the assembly of the connector 111 and the low-voltage connecting line 112. Compared with the manual assembly method one by one in the prior art, this method can not only improve the assembly efficiency of the low-voltage connecting line 112 and the connector 111, but also ensure that the terminals and sockets in the low-voltage connecting line 112 are always inserted horizontally during the assembly process, thereby avoiding damage caused by uneven insertion of the terminals into the sockets, thereby improving the effectiveness of the assembly of the low-voltage connecting line 112 and the connector 111.

[0030] At the same time, the automatic plug-in method is more accurate than the manual plug-in method, which avoids the situation where the low-voltage connecting line 112 and the connector 111 are not properly plugged in during manual plug-in, thereby ensuring the assembly quality between the two and facilitating subsequent use.

[0031] Embodiment 2: Figure 1 , Figure 2 as well as Figures 6 to 8As shown, the low-voltage wiring harness assembly device for automobiles also includes a storage replacement mechanism provided on the assembly platform 1 and the wall slot plate 21. The storage replacement mechanism includes a storage plate 31 fixedly connected to the upper surface of the two wall slot plates 21. The storage plate 31 is located at a position close to the side of the small motor 26. The storage plate 31 is evenly provided with storage slots 32 corresponding to the position of the receiving slot 24. Each storage slot 32 is through-through from top to bottom. Each storage slot 32 is interconnected with the corresponding receiving slot 24, and the shape of each storage slot 32 is the same as that of the receiving slot 24. That is, the terminal of the low-voltage connecting line 112 can also be placed inside each storage slot 32, and multiple terminals can be stacked up and down in the storage slot 32. Two electrically controlled telescopic rods 33 are fixedly installed on the upper surface of the assembly platform 1 close to the storage plate 31, and the two electrically controlled telescopic rods 33 are controlled by the above-mentioned controller 12. Each storage slot 32 is slidably connected with a corresponding slot block 321, and the slot block 321 extends to the outside of the storage slot 32 near the side of the electric telescopic rod 33. Only one slot block 321 is shown in the figure, and the slot block 321 can be slid from the storage slot 32 from bottom to top. When in use, one slot block 321 can be placed in each storage slot 32. The telescopic ends of the two electric telescopic rods 33 are fixedly connected with a comb plate 34, and the top of the comb plate 34 is fixedly connected with a plurality of blocking plates 35. The plurality of blocking plates 35 are horizontally distributed, and two adjacent blocking plates 35 form a group, and the two adjacent blocking plates 35 are located between the bottom of the storage plate 31 and the top of the placement plate 23. Specifically, the two blocking plates 35 are located between the bottom of the storage slot 32 and the top of the receiving slot 24, and each blocking plate 35 can be horizontally displaced between the bottom of the storage slot 32 and the top of the placement plate 23. Initially, the blocking plate 35 is located between two adjacent terminals. A side of each blocking plate 35 close to the receiving plate 31 is provided with an inclined surface.

[0032] When using: Figure 6 As shown, in advance, the staff can place the required terminals of each low-voltage connecting wire 112 in the storage slot 32 in a stacked manner. Since the shape of each storage slot 32 is compatible with the shape of the terminal, the staff can easily stack each terminal in the corresponding storage slot 32. After the stacking is completed, the staff manually puts the slot block 321 into the corresponding storage slot 32 from top to bottom, so that the slot block 321 contacts the top terminal in the storage slot 32. Under the gravity of the slot block 321, the stability and tightness of the stacking between the terminals are guaranteed. The use of each storage slot 32 can provide storage space for each low-voltage connecting wire 112. Compared with the method of directly scattering the low-voltage connecting wire 112 on the work surface in the prior art, this method can ensure that each low-voltage connecting wire 112 is neatly and orderly placed, avoiding the situation of entanglement between each low-voltage connecting wire 112, thereby ensuring the orderliness of the staff's work surface.

[0033] When the next connector 111 needs to be connected and assembled with each low-voltage connection line 112, the staff controls the output shaft of the small motor 26 to rotate in the opposite direction through the controller 12, thereby driving the screw 27 to rotate in the opposite direction, and then prompting the placement plate 23 and each receiving slot 24 to translate and reset in the opposite direction. When the placement plate 23 is reset to the bottom of the receiving plate 31, the controller 12 will control the telescopic ends of the two electrically controlled telescopic rods 33 to be retracted horizontally, driving the comb plate 34 and each blocking plate 35 to first move horizontally away from the receiving plate 31. As each blocking plate 35 moves horizontally away from the receiving plate 31, the terminals of each low-voltage connection line 112 stacked inside the receiving slot 32 will move downward under the action of their own gravity and the gravity of each slot block 321, thereby prompting one terminal to fall into the corresponding receiving slot 24. Subsequently, the controller 12 controls the telescopic ends of the two electrically-controlled telescopic rods 33 to extend horizontally, driving each blocking plate 35 to reset horizontally. During the resetting process, the inclined surface of each blocking plate 35 will come into contact with the gap between two adjacent terminals, and as the inclined surface continues to translate, it will prompt each terminal located above the blocking plate 35 to move up synchronously inside the storage slot 32 for subsequent continued use.

[0034] As the terminal of the new low-voltage connecting line 112 falls into the corresponding receiving groove 24, the small motor 26 is started again through the controller 12 to drive the screw rod 27 to rotate forward, thereby driving the terminals inside each receiving groove 24 to move horizontally again, thereby realizing the connection and assembly between the second connector 111 and each low-voltage connecting line 112. In this way, the above steps can be repeated to realize the connection and assembly between each connector 111 and each low-voltage connecting line 112.

[0035] Therefore, by utilizing the cooperation between the storage groove 32, the baffle plate 35 and other components and the automatic assembly mechanism, the staff does not need to manually place the required low-voltage connecting wires 112. After a connector 111 and each low-voltage connecting wire 112 are assembled, each new low-voltage connecting wire 112 can automatically fall into the corresponding receiving groove 24 for continued assembly. This method not only reduces the workload of the staff, but also can further improve the connection and assembly efficiency of the connector 111 and the low-voltage connecting wire 112.

[0036] Embodiment 3: Figure 1 , Figure 2 as well as Figures 9 to 12As shown, a follow-up processing mechanism is commonly provided on the assembly table 1 and the wall groove plate 21, and the follow-up processing mechanism includes a top groove 41 opened on the top surface of the two wall groove plates 21, and a cross plate 42 is commonly slidably connected to the two top grooves 41, and a frame-shaped plate 43 is fixedly connected to the bottom of the cross plate 42, and an extension frame 431 is fixedly provided on the frame-shaped plate 43 and at a position corresponding to the connecting plate 29 and the slider plate 22. Specifically, the bottom surface height of the extension frame 431 corresponding to the connecting plate 29 is higher than the height of the above-mentioned nut sleeve block 28, and the extension frame 431 can allow the connecting plate 29 to move horizontally, that is, the frame-shaped plate 43 and the extension frame 431 will not block the horizontal displacement of the nut sleeve block 28 and the connecting plate 29; and the extension frame 431 corresponding to the position of the slider plate 22 can allow the slider plate 22 to pass horizontally. A plurality of soft brush groups 44 are evenly arranged on the frame plate 43, and four soft brush groups 44 form a group. The four soft brush groups 44 are distributed in a rectangular shape, and the position of each soft brush group 44 corresponds to the position of each receiving slot 24. Specifically, the four soft brush groups 44 can contact the four outer surfaces of the terminals in the low-voltage connecting line 112, and the placement plate 23 can horizontally pass through the frame plate 43 and the soft brush groups 44. In addition, a negative pressure dust suction device, such as a vacuum cleaner, can be installed on the upper surface of the assembly table 1. The negative pressure dust suction device is a prior art, so it is not shown in the figure, and the dust suction port in the negative pressure dust suction device is located directly below each soft brush group 44. One end of the horizontal plate 42 is fixedly connected to a matching plate 47, and a short rod 45 is rotatably connected to the upper surface of the assembly table 1 and one side close to the matching plate 47. An inclined disk 46 is fixedly provided on the outer wall of the end of the short rod 45 close to the matching plate 47. A bayonet is provided at the bottom of the matching plate 47, and the bayonet and the inclined disk 46 are slidably matched. A synchronous component 48 is transmission-connected between the end of the short rod 45 away from the inclined disk 46 and the output shaft of the small motor 26. The synchronous component 48 consists of two synchronous wheels and a belt transmission-connected between the two synchronous wheels, one of which is fixedly connected to the output shaft of the small motor 26, and the other is fixedly connected to the end of the short rod 45 away from the inclined disk 46.

[0037] In use: In addition, considering that the terminals of the low-voltage connecting wire 112 will have some dust and impurities attached to their surfaces during the aforementioned assembly or shipment process, in order to ensure the effectiveness of the connection and assembly between the connector 111 and the low-voltage connecting wire 112. In the process of the placement plate 23 driving each terminal to horizontally move toward each jack of the connector 111, each terminal will also horizontally pass between each soft brush group 44, thereby prompting each soft brush group 44 to stick to the four outer surfaces of each terminal. At the same time, with the rotation of the small motor 26, the short rod 45 and the inclined disk 46 will be driven to rotate synchronously through the synchronization component 48, and after the inclined disk 46 rotates, under the cooperation of the matching plate 47 and the inclined disk 46, the cross plate 42 will be driven to reciprocate horizontally along the trajectory of the top groove 41, thereby driving each soft brush group 44 to reciprocate and translate along the four outer surfaces of each terminal, thereby scraping the four outer surfaces of each terminal. Meanwhile, during the scraping process of each soft brush group 44 , the negative pressure dust suction device can be started to automatically collect the dust and impurities dropped by the scraping brushes through the dust suction port to prevent the impurities and dust from falling on the upper surface of the assembly table 1 .

[0038] Therefore, in the process of horizontal movement and assembly of each terminal, a corresponding soft-bristle brush group 44 is arranged on the movement path of each terminal, and each soft-bristle brush group 44 can move back and forth simultaneously along the four outer surfaces of the terminal, thereby effectively scraping off the dust and impurities attached to the outer surface of the terminal, preventing impurities from adhering to the terminal, thereby preventing dust and impurities from affecting the plug-in fit between the low-voltage connecting line 112 and the connector 111, thereby ensuring the assembly quality between the two.

[0039] Embodiment 4: Based on the automotive low-voltage wiring harness assembly device in the above embodiments 1 to 3, a method for using the automotive low-voltage wiring harness assembly device is now proposed. The method uses the automotive low-voltage wiring harness assembly device as described above, and the method comprises the following steps: Step 1: A worker manually places a connector 111 horizontally on the positioning plate 11 , ensuring that the jack faces the placement plate 23 .

[0040] Step 2: Before stacking the low-voltage connecting wires 112, first retract the telescopic ends of the two comb plates 34 through the controller 12 to prompt each blocking plate 35 to move away from the storage plate 31, and then place each required low-voltage connecting wire 112 in the interior of each storage groove 32 in sequence by stacking them up and down. Subsequently, control the telescopic ends of the comb plates 34 to extend horizontally to prompt each blocking plate 35 to reset.

[0041] Step three: Start and control the output shaft of the small motor 26 through the controller 12 to rotate in the forward direction, driving the placement plate 23 and the various terminals placed in the accommodating grooves 24 to move horizontally toward the direction close to the socket on the connector 111 until the terminal is horizontally inserted into the corresponding socket, thereby realizing the connection and assembly between the connector 111 and the various low-voltage connecting lines 112.

[0042] Step 4: After the connection and assembly of the connector 111 and each low-voltage connecting line 112 are completed, the staff will take them away, and then control the output shaft of the small motor 26 to rotate in the opposite direction through the controller 12, driving each placement plate 23 and each receiving slot 24 to translate and reset in the opposite direction.

[0043] Step 5: After each receiving slot 24 is reset, the telescopic end of the comb plate 34 is retracted, driving each blocking plate 35 to move synchronously, and then the terminal in the next low-voltage connecting line 112 falls downward into the corresponding receiving slot 24 under the action of gravity.

[0044] Step 5: Repeat the above steps 1 and 3 to realize the connection and assembly of the connector 111 and each low-voltage connecting line 112 again.

[0045] Step 6: During the process of connecting and assembling the connector 111 and the low-voltage connecting wires 112, the four outer surfaces of the terminals are brushed by the soft-bristle brush groups 44 to remove dust and impurities on the outer surfaces of the terminals.

[0046] Furthermore, in step 2, after the low-voltage connecting wires 112 are stacked, each slot block 321 is placed into the corresponding receiving slot 32 and pressed against the upper surface of the terminal of the low-voltage connecting wire 112 located inside the receiving slot 32 and at the top.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
