Description

Technical Field

[0001] This invention relates to the technical field of automated equipment, and in particular to a wire harness assembly machine. Background Technology

[0002] Existing as Figure 1 The connector shown includes two plastic housings 9, and wire harnesses 91 are inserted into the two plastic housings 9. The wire harnesses 91 are U-shaped and there are two sets of wire harnesses 91. The two sets of wire harnesses 91 have different lengths. Each set of wire harnesses 91 has multiple wires in the length direction of the plastic housing 9. A locking block 92 for fixing the wire harnesses 91 is inserted into one side of the plastic housing 9. The locking block 92 is inserted through the plastic housing 9.

[0003] Currently, the assembly of these connectors relies primarily on manual labor. Operators first insert two sets of wire harnesses into the plastic housing sequentially, and then insert the locking block from the side to complete the assembly. However, during actual assembly, operators need to adjust the position of the wire harnesses before inserting them, ensuring that the bent parts of the wire harnesses align with the slots on the plastic housing. Since each set of wire harnesses consists of multiple strands, this alignment process takes a considerable amount of time, significantly impacting actual production. Furthermore, after assembly, product inspection is still required, and the varying skill levels of these inspectors further affect assembly efficiency.

[0040] During assembly, the carrier 21 flows to the feeding device 3 via the transmission line 22. The side baffle 381 extends and intercepts the carrier 21. Then, the lifting plate 382 pushes up, and the carrier 21 is lifted to fix its position. The plastic shell in the feeding vibratory plate 32 flows to the feeding bracket 31 via the feeding line 33. Then, the shell gripper 35, driven by the feeding cylinder 36 and the lifting cylinder 37, grips the plastic shell and places it on the carrier 21. Then, the moving cylinder 386 pushes the lifting plate 382, ​​causing the carrier 21 to move forward. The shell gripper 35 then places a second plastic shell into the carrier 21.

[0041] A cable pre-insertion assembly 41 and a cable insertion assembly 42 are provided on one side of the insertion line 23.

An assembly motor 57 is fixedly connected to the side of the assembly bracket 51 away from the transmission line 22. The assembly motor 57 is connected to the end of the drive link 56 away from the slider 521, thereby driving the drive link 56 to rotate. The assembly bracket 51, the moving shaft 52, and the clamping claw 53 together constitute a lock block assembly device 5 for inserting lock blocks. After the clamping claw 53 clamps the lock block, it is inserted into the plastic shell and passes through the wire harness, thereby fixing the wire harness inside the plastic shell.

[0046] A lock block detection device 6 is provided alongside the lock block assembly device 5. The lock block detection device 6 includes a detection platform 61 positioned on one side of the transmission line 22.

[0047] A feeding line 11 is installed next to the base 1. A tray-mounting robot 8 is placed near the feeding line 11 on the base 1. An appearance inspection camera 7 is placed between the tray-mounting robot 8 and the locking block detection device 6. When the carrier 21 passes the appearance inspection camera 7, the appearance inspection camera 7 takes a picture and performs appearance inspection. The tray-mounting robot 8 transports the finished product that has passed the locking block detection device 6 and the appearance inspection camera 7 onto the feeding line 11. A carrier positioning component 38 is also provided at the tray-mounting robot 8. This carrier positioning component 38 is based on the carrier positioning component 38 of the feeding device 3, the difference being that there is no moving cylinder 386.

[0048] The implementation principle of this embodiment is as follows: During the assembly operation, the carrier 21 on the transmission line 22 moves to the loading device 3. After being intercepted by the carrier positioning component 38, the outer shell gripper 35 inserts two plastic shells into the carrier 21. Then, it is transferred by the transfer device 12 to the insertion line 23. After passing through two sets of pre-insertion components 41 and insertion components 42, the assembly of the inner and outer wire harnesses is completed. Then, it moves back to the transmission line 22 via the transfer device 12 at the other end. Then, the locking block assembly device 5 performs the locking block assembly operation, completing the entire assembly process. Then, it continues to flow along the transmission line 22, passing through the locking block detection device 6 and the appearance inspection camera 7, and is moved by the tray-loading robot to the unloading line 11, completing the entire assembly and inspection process. This application uses specific wire harness assembly equipment to replace manual labor, avoiding processing differences caused by the operator's skill level, improving assembly efficiency, and also improving product quality.
