[0023] Before introducing the wiring harness assembly device of the embodiment of the present invention, it is necessary to explain the oxygen sensor to which the wiring harness assembly device of the present invention is applicable. Figure 4 As shown, the oxygen sensor includes an oxygen sensor base 910 and a wiring harness 920 connected to one end of the oxygen sensor base 910 , and a connector of the wiring harness 920 is sealed and connected to the oxygen sensor.

[0024] Please refer to Figure 1 、 Figure 2 and Figure 4 As shown, an embodiment of the present invention provides a wiring harness assembly device, including a wiring harness pressing module 300 and a test module 340. The wiring harness pressing module 300 includes a wiring harness positioning seat 310 and a wiring harness assembly pressure head 320. The wiring harness positioning seat 310 is suitable for carrying the wiring harness 920 and the oxygen sensor base 910. The wiring harness assembly pressure head 320 is suitable for pressing the oxygen sensor base 910 to assemble it with the connector of the wiring harness 920; the test module 340 includes a test connector 341 and a test placement seat 344. The test placement seat 344 is located between the wiring harness positioning seat 310 and the test connector 341. The test placement seat 344 is provided with a test placement groove 3441. The test placement groove 3441 is suitable for placing part of the wiring harness 920; the test connector 341 is suitable for being electrically connected to the wiring harness 920.

[0025] According to the oxygen sensor assembly device of the embodiment of the present invention, the connector of the wiring harness 920 is fixed to the wiring harness positioning seat 310, and the rest of the wiring harness 920 extends and passes through the test placement slot 3441 and is connected to the test connector 341. The test placement slot 3441 divides the wiring harness 920 into two parts while carrying the wiring harness 920. The first part is the part from the wiring harness positioning seat 310 to the test placement slot 3441, and the second part is the part from the test placement slot 3441 to the test connector 341. It can be understood that due to the limitation of the wiring harness 920 placement slot, the wiring harness 920 is placed in the test position. The bending between the two parts of the wiring harness 920 will not affect each other. Specifically, if the remaining length of the first part of the wiring harness 920 is different based on different types of wiring harnesses 920, the first part of the wiring harness 920 will bend to ensure that the connector of the wiring harness 920 is located at the wiring harness positioning seat 310, and the bending deformation of the first part of the wiring harness 920 is limited to between the wiring harness positioning seat 310 and the test placement slot 3441, and will not affect the second part of the wiring harness 920. The second part of the wiring harness 920 can be stably connected to the test connector 341.

[0026] Subsequently, the harness assembly pressure head 320 presses against the oxygen sensor base 910 to assemble it with the connector of the harness 920. When the assembly is completed, the current of the test connector 341 is connected to the oxygen sensor base 910, and the oxygen sensor is functionally tested.

[0027] It should be noted that in the related art, during the production process of oxygen sensors, the assembly of the oxygen sensor base 910 and the wiring harness 920 and the testing of the oxygen sensor are usually completed by different machines, and the staff are required to carry the assembled oxygen sensor from different modules and install the oxygen sensor for testing, which results in low production efficiency; and even when the wiring harness pressing module 300 and the test module 340 are combined together, due to the different lengths of the wiring harness 920 of different types of oxygen sensors, when the connector of the wiring harness 920 is fixed to the wiring harness positioning seat 310, the other end is affected by the bending of the wiring harness, and there is a certain insertion angle tilt, resulting in an unstable connection with the test connector 341, that is, it cannot be well adapted to different types of oxygen sensors.

[0028] According to the oxygen sensor assembly equipment of an embodiment of the present invention, the wire harness pressing module 300 and the test module 340 are combined, and the electrical connection between the wire harness 920 and the test connector 341 is completed while the wire harness 920 is loaded onto the wire harness positioning seat 310, ensuring that the test connector 341 can be immediately functionally tested after the connector of the wire harness 920 is pressed onto the oxygen sensor substrate 910, thereby effectively improving production efficiency; further, by setting a test placement groove 3441, the wire harness 920 is split into two parts for limiting, and the bending of the wire harness 920 between different parts does not affect each other, ensuring that for wire harnesses 920 of different lengths, the bending deformation of the wire harness 920 can be limited to one of the two parts, ensuring that the connector of the wire harness 920 can be placed on the wire harness positioning seat 310 while the other end of the wire harness 920 can also be stably connected to the test connector 341.

[0029] In some embodiments, combined Figures 1 to 4 As shown, the wiring harness assembly device further includes a marking module 350 , which is located between the test placement slot 3441 and the test connector 341 and faces the wiring harness 920 .

[0030] In this embodiment, the marking module 350 is used to print identification information on the surface of the wire harness 920. The marking process is performed simultaneously with the press-fitting process of the wire harness press-fitting module 300, effectively improving the production efficiency of the oxygen sensor.

[0031] In this embodiment, the marking module 350 can be a laser printer, a laser engraving printer, etc.

[0032] In some embodiments, combined Figures 1 to 4 As shown, the extension direction of the test placement slot 3441 is the same as the extension direction of the test connector 341, so that the extension paths of the parts of different harnesses 920 located between the test placement seat 344 and the test connector 341 are the same.

[0033] In this embodiment, the extension direction of the test placement slot 3441 is the same as the extension direction of the test connector 341, so that the part of the wiring harness 920 between the test connector 341 and the test positioning slot is always straight and in the same position, to ensure that the marking module 350 can stably print marks on the wiring harness 920.

[0034] In other embodiments, the marking module 350 can also be set above the test placement slot 3441, and the wiring harness 920 in the test placement slot 3441 can be placed along the extension direction of the test placement slot 3441. Similarly, the position of the printed mark on each wiring harness 920 can always correspond to the marking module 350.

[0035] In other embodiments, the test placement slot 3441 can also be directly extended to dock with the test connector. In this case, for any shape of the test placement slot 3441, the printing position on each wiring harness 920 can always be kept corresponding to the marking module 350.

[0036] In some embodiments, combined Figures 1 to 4 As shown, the test module 340 also includes an anti-foolproof buckle 342, which is movably connected to one side of the test connector 341. The anti-foolproof buckle 342 can switch between an anti-foolproof state and an open state under the action of an external driving force; the anti-foolproof state is a state in which the hook of the anti-foolproof buckle 342 at least partially overlaps with the test connector 341 on the orthographic projection of the disengagement direction of the test connector 341 to limit the wiring harness 920 from disengaging from the test connector 341; the open state is a state in which the hook of the anti-foolproof buckle 342 does not overlap with the test connector 341 on the orthographic projection of the disengagement direction.

[0037] In this embodiment, the state switching of the anti-foolproof buckle 342 is adapted to the detection result of the test connector 341. For example, when the detection result of the test connector 341 is unqualified, the anti-foolproof buckle 342 switches from the open state to the anti-foolproof state to restrict the staff or the handling module from pulling out the wiring harness 920 from the test connector 341.

[0038] Of course, it can also be, for example: after the wiring harness 920 is plugged into the test connector 341, the anti-foolproof buckle 342 switches from the open state to the anti-foolproof state. When the test result of the test connector 341 is qualified, the anti-foolproof buckle 342 switches from the anti-foolproof state to the open state again, and if the test result is unqualified, the anti-foolproof buckle 342 remains in the anti-foolproof state.

[0039] In this embodiment, by setting the state switching of the anti-foolproof buckle 342, it is effectively prevented that the staff or the handling module mixes the oxygen sensors with qualified and unqualified test results of the test connector 341.

[0040] In this embodiment, for an oxygen sensor that fails the test, a worker needs to confirm and release the foolproof state of the foolproof buckle 342 before the sensor can be removed, thereby ensuring that each unqualified oxygen sensor is scrapped.

[0041] In this embodiment, the “external driving force” can be Figure 4 The push is provided by the cylinder, of course, it can also be a motor, oil cylinder, etc.

[0042] In some embodiments, combined Figures 1 to 4 As shown, the test module 340 also includes a reset member 343, the two ends of which are respectively connected to the anti-foolproof buckle 342 and the test connector 341, and the reset member 343 is suitable for pushing the anti-foolproof buckle 342 to switch from the open state to the anti-foolproof state.

[0043] In this embodiment, when the test connector 341 is not in use, the anti-foolproof buckle 342 is in an anti-foolproof state under the action of the reset member 343. When the wiring harness 920 is plugged into the test connector 341, the wiring harness 920 pushes the anti-foolproof buckle 342 and compresses the reset member 343, so that the anti-foolproof buckle 342 switches from the anti-foolproof state to the open state until the wiring harness 920 is fully plugged into the test connector 341. The wiring harness 920 releases the push on the anti-foolproof buckle 342, and under the action of the reset member 343, the anti-foolproof buckle 342 switches from the open state to the anti-foolproof state to limit and fix the wiring harness 920. When the test connector 341 is tested, for the wiring harness 920 that passes the test, the anti-foolproof buckle 342 will switch from the anti-foolproof state to the open state under the action of an external driving force; for the wiring harness 920 that fails the test, the anti-foolproof buckle 342 continues to maintain the anti-foolproof state.

[0044] In this embodiment, the reset member 343 enables the anti-foolproof buckle 342 to automatically switch from the open state to the anti-foolproof state without external drive, effectively reducing the control process required for external drive, and the physical structure is simpler and more reliable.

[0045] In this embodiment, the reset member 343 may be a linear spring. Of course, a torsion spring, a silicone pad, etc. may also be used.

[0046] In some embodiments, combined Figure 2 As shown, the test module 340 further includes a first detection member 345 , the detection end of the first detection member 345 faces the test placement slot 3441 and is suitable for detecting the wiring harness 920 .

[0047] In this embodiment, when the first detection member 345 determines that the wiring harness 920 is present, the wiring harness assembly press head 320 can be activated to press down and the test connector 341 can be detected. The first detection member 345 can be a component with object recognition capabilities such as a laser sensor or an image recognition device.

[0048] In some embodiments, combined Figure 1 and Figure 2 As shown, the wire harness pressing module 300 also includes a guiding mechanism 330, and the wire harness positioning seat 310, the guiding mechanism 330 and the wire harness assembly press head 320 are arranged in sequence along the third direction; the guiding mechanism 330 includes a guiding clamp 331, and the guiding clamp 331 is suitable for clamping the limiting oxygen sensor base 910 so that the connector of the oxygen sensor base 910 and the connector of the wire harness 920 correspond.

[0049] In this embodiment, the guide clamp 331 clamps and positions the oxygen sensor base 910 so that the oxygen sensor base 910 corresponds to the wire harness 920 positioned in the lower wire harness positioning seat 310, ensuring that the wire harness 920 and the oxygen sensor base 910 are stably assembled under the pressure of the wire harness assembly pressure head 320.

[0050] In some embodiments, combining 1 and Figure 2 As shown, the guiding mechanism 330 also includes a guiding bracket 332 and a guiding movable module 333. The guiding bracket 332 is connected to the wire harness positioning seat 310. The first end of the guiding movable module 333 is slidably connected to the guiding bracket 332 along the third direction, and the second end of the guiding movable module 333 is connected to the guiding clamp 331.

[0051] In this embodiment, a sliding connection is set between the guiding movable module 333 and the guiding bracket 332, so that the guiding clamp 331 connected to the guiding movable module 333 can move synchronously with the downward pressure of the wiring harness assembly pressure head 320, that is, during the entire process of the oxygen sensor base 910 being pressed and moved by the wiring harness assembly pressure head 320, the guiding clamp 331 always clamps and positions the oxygen sensor base 910, ensuring that the connector of the oxygen sensor base 910 corresponds to the connector of the wiring harness 920, thereby improving the assembly yield rate.

[0052] In this embodiment, the "sliding connection" can be achieved through a slide module, a screw module, a hole-shaft structure, etc.

[0053] In some embodiments, combined Figure 2 As shown, the wiring harness positioning seat 310 is provided with a wiring harness positioning groove 311. The cross-sectional area of ​​the wiring harness positioning groove 311 gradually decreases along the groove opening toward the groove bottom. That is, as the wiring harness 920 is placed into the wiring harness positioning groove 311, the groove wall of the wiring harness positioning groove 311 gradually tightens, reducing the difficulty of the wiring harness 920 entering the wiring harness positioning groove 311 while ensuring the positioning accuracy of the wiring harness 920 by the wiring harness positioning groove 311.

[0054] On the other hand, an embodiment of the present invention further provides an oxygen sensor assembly device, such as the wire harness assembly device of the above embodiment.

[0055] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the scope of the present invention.
