DETAILED DESCRIPTION

[0048] The technical solution of the present application will be described clearly and completely below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0049] During the crimping process, the wiring harness will be affected by the unqualified crimping between the wire and the terminal (for example, the insulation of the wire is crimped with the terminal or the wiring harness is broken during the crimping process, etc.), which will affect the conductive performance of the terminal. At present, directly inserting the crimped terminals into the sockets will result in a high defective rate of the module connector after the sockets are completed. At the same time, each wiring harness in the module connector after the sockets are completed needs to be tested separately to find the specific wiring harness or terminal that causes the module connector to become a defective product.

[0050] To solve the above problems, the following Figure 1-Figure 6, describes the wire harness assembly device provided in the embodiment of the present application. The wire harness assembly device includes an operating table 100, a crimping mechanism 400, a detection mechanism 500 and a socket mechanism 600. The crimping mechanism 400, the detection mechanism 500 and the socket mechanism 600 are all arranged on the operating table 100. The crimping mechanism 400 is used to crimp the terminals to the two ends of the wire harness; the detection mechanism 500 is located on the discharge side of the crimping mechanism 400, and is used to detect the conductivity of the terminals crimped to the two ends of the wire harness; the socket mechanism 600 is located on the discharge side of the detection mechanism 500, and is used to insert the terminals that have passed the conductivity performance test into the sheath.

[0051] By setting the detection mechanism 500 between the crimping mechanism 400 and the socket mechanism 600, after the terminals are crimped to the two ends of the wire harness, the conductivity of the terminals crimped to the two ends of the wire harness can be detected in time. If the conductivity of the terminals crimped to the two ends of the wire harness is unqualified, the assembly link is exited; if the conductivity of the terminals crimped to the two ends of the wire harness is qualified, the socket mechanism 600 is continued. The socket mechanism 600 inserts the terminals that have passed the conductivity detection into the sheath. In this way, the terminals after crimping can be preliminarily screened to filter out the unqualified crimping products caused by the crimping of the insulation skin of the wire harness and the terminal and the disconnection of the connection between the wire harness and the terminal, and prevent the unqualified crimping terminals from entering the socket mechanism 600, thereby improving the yield rate of the connector after the socket.

[0052] Reference Figure 4 As shown, in some embodiments of the present application, the detection mechanism 500 includes a first conductive clip 510 and a second conductive clip 520, and the first conductive clip 510 and the second conductive clip 520 are arranged opposite to each other. The first conductive clip 510 and the second conductive clip 520 respectively detect the conductivity performance of the terminals crimped at both ends of the wiring harness by clamping the corresponding terminals. In some specific embodiments, the first conductive clip 510 is arranged on the left side of the operating table 100, and the second conductive clip 520 is arranged on the right side of the operating table 100. The first conductive clip 510 and the second conductive clip 520 are respectively electrically connected to a multimeter or a resistance tester through wires. When the terminals crimped at both ends of the wiring harness are respectively electrically connected to the first conductive clip 510 and the second conductive clip 520, the terminals are tested for their conductivity. Specifically: if the measured resistance is less than 30Ω, it indicates that the circuit is conductive, and it is determined that the terminals crimped at both ends of the wiring harness have good conductivity, and the socket mechanism 600 can continue to be entered; if the measured resistance is greater than 30Ω, it indicates that there are virtual contacts in the circuit, for example, there is a break at the crimping position or the terminal is crimped with the insulation skin, and it is determined that the terminals crimped at both ends of the wiring harness have poor conductivity, and they are withdrawn from the assembly process.

[0053] Reference Figure 4As shown, in some embodiments of the present application, the jack mechanism 600 includes a first jack clamp 610, a second jack clamp 620, a first sheath clamp 630 and a second sheath clamp 640, wherein the first jack clamp 610 and the second jack clamp 620 are arranged opposite to each other for clamping the wiring harness; the first sheath clamp 630 and the second sheath clamp 640 are arranged opposite to each other for clamping the sheath respectively; the first jack clamp 610 and the second jack clamp 620 can move between the first sheath clamp 630 and the second sheath clamp 640 along the first direction, and the first jack clamp 610 and the second jack clamp 620 move away from each other along the second direction so that the terminal that has passed the conductivity performance test is plugged into the corresponding sheath, the first direction is the length direction of the operating table 100, and the second direction is the width direction of the operating table 100; the first jack clamp 610 and the second jack clamp 620 move closer to each other along the first direction to detect the plug-in firmness of the terminal and the sheath. In some specific embodiments, the first jack clamp 610 and the first sheath clamp 630 are respectively arranged on the left side of the operating table 100, and the second jack clamp 620 and the second sheath clamp 640 are respectively arranged on the right side of the operating table 100; the jack mechanism 600 also includes a movable module, which can drive the first jack clamp 610 and the second jack clamp 620 to move simultaneously along the length direction of the operating table 100 or the width direction of the operating table 100, and the movable module is a cylinder, a hydraulic cylinder, an electric cylinder, or a linear slide.

[0054] After the first jack clamp 610 and the second jack clamp 620 clamp the wire harness, the first jack clamp 610 and the second jack clamp 620 move with the wire harness along the length direction of the operating table 100 to a position between the first sheath clamp 630 and the second sheath clamp 640; then, the first jack clamp 610 and the second jack clamp 620 move away from each other along the second direction, so that the terminal that has passed the conductivity performance test is plugged into the corresponding sheath; after plugging, the first jack clamp 610 and the second jack clamp 620 approach each other along the first direction. It should be noted that the distance between them is very small in order to pull back the terminal inserted into the sheath to detect the firmness of the connection between the terminal and the sheath. If the connection between the terminal and the sheath is not firm, the terminal will be pulled out of the sheath and needs to be reinserted; if the connection between the terminal and the sheath is firm, the first jack clamp 610 and the second jack are reset.

Specifically, the first conductive clip 510 and the first socket clip 610 are installed on the same mobile module, and the second conductive clip 520 and the second socket clip 620 are installed on the same mobile module, so that when the first socket clip 610 and the second socket clip 620 hold the wiring harness, the first conductive clip 510 and the second conductive clip 520 can timely detect the conductive performance of the terminal, thereby saving processes and improving assembly efficiency.
