In different embodiments of the present invention, the sequence of the steps can be adjusted according to the adjustment of the process.

[0049] In the process of wire harness production, multiple wires need to be assembled together. Each end of the wire is connected with a terminal, so multiple terminals need to be inserted into the same terminal housing to form a connection structure. After assembly, it is necessary to determine whether each terminal is inserted in place. Therefore, a terminal position inspection device is needed to check.

[0053] Figure 4 A schematic side view of a terminal in-position inspection device according to an embodiment of the present invention is shown.

[0054] A terminal in-place inspection device includes a base 101, an upper support structure 102, a correction block 103, a correction block handle 1031, a correction block fixing structure 104, a lifting structure 105, a locking structure 106, a locking cylinder 107, a pull-down mechanism 108, and a horizontal cylinder 109.

[0055] The upper support structure 102 is disposed on the base 101. The top surface of the upper support structure 102 has a terminal lifting structure 105, the lower surface of the lifting structure 105 is flush with the lower surface of the top of the upper support structure 102, and the upper surface of the lifting structure 105 is recessed downward relative to the upper surface of the top of the upper support structure 102. The lifting structure 105 is an arc-shaped structure with a hollow middle portion, and the hollow portion is rectangular. The lifting structure 105 can support the connection structure of the wiring harness. The lifting structure 105 has an opening.

[0056] The locking structure 106 is connected to the locking cylinder 107, and the locking cylinder 107 drives the locking structure 106 to move in the horizontal direction. The locking cylinder 107 is arranged on the top surface of the upper support structure 102. Two sets of locking structures 106 and locking cylinders 107 are relatively arranged on both sides of the lifting structure 105, and the two locking structures 106 can be driven by the locking cylinders 107 to move toward each other to clamp the object between them.

[0057] The correction block fixing structure 104 is arranged on the top surface of the upper support structure 102. The correction block 103 is movably connected to the correction block fixing structure 104. The bottom surface of the correction block 103 has a slot 1032, which is located just above the lifting structure 105 and is used to correct the position of the connection structure placed on the lifting structure 105, more specifically, just above the hollow of the lifting structure 105.

[0058] The correction block 103 can be pulled up and pushed down by the correction block handle 1031 to move up and down along the correction block fixing structure 104. When the correction block 103 moves downward and the connecting structure is inserted into the slot 1032, the position of the connecting structure is accurate.

[0059] The pull-down mechanism 108 is located below the top of the upper support structure 102. The pull-down mechanism 108 has a terminal clamping claw. The pull-down mechanism 108 can move the terminal clamping claw up and down.

[0060] The horizontal cylinder 109 is located below the pull-down mechanism 108 and is configured to drive the pull-down mechanism to move in the horizontal direction. A support block 110 is provided below the pull-down mechanism 108 and is fixedly connected to the pull-down mechanism 108. The support block 110 is connected to the piston rod of the horizontal cylinder 109.

[0061] Figure 5 A schematic diagram of two pull-down mechanisms on the left side of an embodiment of the present invention is shown.

[0062] Figure 6 A schematic diagram showing the distribution of five terminal clamps according to an embodiment of the present invention is shown.

[0063] Figure 7 A schematic diagram showing the distribution of five pull-down mechanisms according to an embodiment of the present invention is shown.

[0064] like Figure 5 As shown, the pull-down mechanism includes a fixing plate 11 , a slide rail 12 , upper and lower cylinders 13 , a clamp fixing plate 14 , a terminal clamp 15 , a limit block 16 , and a bottom plate 17 .

[0065] The slide rail 12 is located on the side of the fixed plate 11 and above the horizontal cylinder 109. The piston rods of the upper and lower cylinders 13 are fixedly connected to the clamping jaw fixing plate 14, and the clamping jaw fixing plate 14 is slidably connected to the slide rail 12. The upper and lower cylinders 13 can drive the clamping jaw fixing plate 14 to move up and down along the slide rail 12 to drive the terminal clamping jaw 14 to move up and down.

[0066] The limiting block 16 is disposed on the side of the fixing plate 11 and is located below the slide rail 12 to limit the clamping jaw fixing plate 14 and control the downward movement distance of the clamping jaw fixing plate 14 .

[0067] The fixed plate 11 and the upper and lower cylinders 13 are all arranged on a bottom plate 17 , and the bottom plate 17 is connected to the horizontal cylinder 109 .

[0068] like Figure 6 As shown, the terminal clamping claw 15 has a U-shaped opening, and both sides of the U-shaped opening have chamfers. The chamfers are provided to facilitate the terminal to be inserted into the U-shaped opening.

[0069] The number of pull-down mechanisms can be adjusted according to the number of terminals of the wiring harness product, and the position distribution of the pull-down mechanisms corresponds to the distribution of the terminals in the connection structure. In one embodiment of the present invention, the number of pull-down mechanisms is 5, and the distribution is 2 on each side and 1 facing the operator. Figure 6 and 7 shown.

[0070] The four pull-down mechanisms distributed on the left and right will move left and right under the drive of the horizontal cylinder 109, and the pull-down mechanism facing the operator will move forward and backward under the drive of the horizontal cylinder 109. During operation, the five pull-down mechanisms will move toward the middle at the same time under the drive of the horizontal cylinder 109.

[0071] The terminal in place inspection device further comprises a control device, which is electrically connected to the locking cylinder 107, the horizontal cylinder 109 and the upper and lower cylinders 13 to control the operation of each cylinder.

[0072] Figure 8 A schematic diagram showing a partial structure of a wiring harness according to an embodiment of the present invention. Fig. 9 A schematic top view of a connection structure of a wire harness according to an embodiment of the present invention is shown.

[0073] like Figure 8 and 9As shown, the wiring harness includes a connection structure and wires 21. The connection structure 20 includes a housing 22 and a terminal 23 inserted into the housing. The terminal 23 is completely inserted into the housing, and a portion of the terminal 23 is exposed to the outside.

[0074] Fig.10 A schematic diagram showing a connection structure of a wire harness according to an embodiment of the present invention is placed on a supporting structure.

[0075] The inspection steps using the terminal in-place inspection device are as follows:

[0076] The connection structure of the wiring harness is placed on the supporting structure 105, and the exposed terminals are located under the supporting structure 105. Fig.10 shown.

[0077] When the control device is turned on, the control device will first instruct the locking cylinder 107 to operate, driving the locking structure 106 to press against the connecting structure from the side. Then the control device will instruct the horizontal cylinder 109 to operate, driving the pull-down mechanism 108 to move, so that the opening of the terminal clamp 15 clamps the terminal. After that, the control device will instruct the upper and lower cylinders 13 to operate downward, pulling down the terminal. If the terminal is not in place, it will fall off the housing. If it is plugged in place, the terminal clamp 15 will slide off the terminal.

[0078] Finally, the upper and lower cylinders 13 push the clamp fixing plate 14 upward, the horizontal cylinder 109 moves the pull-down mechanism 108 away from the terminal, and the locking cylinder 107 moves the locking structure 106 away from the connecting structure, and the operator removes the wire harness.
