[0002] Automotive wiring harnesses are widely used in new energy vehicles. According to traditional processing techniques and workflows, after assembly, marking lines are drawn on the sleeves of the wiring harness. Currently, this marking is typically done by hand, but hand-drawn markings cannot be completed in one stroke, resulting in uneven lines. Furthermore, the wiring harness needs to be rotated during marking, causing processing difficulties. Additionally, after marking, the harness needs to be moved to the next process step to check its dimensional accuracy. Therefore, hand-drawn markings have many drawbacks, making it essential to design a device that simultaneously checks the dimensions of automotive wiring harnesses and marks them.

[0022] An apparatus for checking the dimensions of automotive wiring harnesses and simultaneously marking them with lines includes:

[0023] Workbench 1;

[0024] A 1:1 length drawing 2 is set on the table surface of the workbench 1 for dimensional inspection of automotive wiring harnesses;

[0025] A wire harness clamping module 3, disposed on the table surface of the workbench 1, is used to clamp the sleeved portion 7 of the automotive wire harness; and,

[0026] Marking pen module 4, installed on the workbench 1, is used to draw marking lines on the sleeved portion 7 of the automotive wiring harness.

[0027] Specifically, such as Figure 1 As shown, in this embodiment, the workbench 1 has a long plate structure. A 1:1 length drawing, consistent with the dimensions of the automotive wiring harness to be inspected, is fixed on the workbench 1 by adhesive or transparent tape. The 1:1 length drawing shows the lengths of each part of the automotive wiring harness and the allowable tolerance range. A wiring harness clamping module 3 and a marking pen line module 4 are also provided on the workbench 1. The wiring harness clamping module 3 and the marking pen line module 4 are positioned at locations corresponding to the positions where the automotive wiring harness has sleeves in the 1:1 length drawing 2, thus facilitating the clamping module 3 to clamp the sleeved part of the automotive wiring harness, and the marking pen line module 4 to draw marking lines on the sleeved part of the automotive wiring harness. The specific operation process is as follows: the assembled automotive wiring harness is placed on the workbench, the sleeved part of the automotive wiring harness is clamped in the module, and while the wiring harness is slowly rotated, the marking pen held in the marking pen line module draws marking lines on the sleeve. Finally, a 1:1 length inspection device is used to check all dimensions of the wiring harness. This utility model discloses a device for simultaneously checking the dimensions of automotive wiring harnesses and drawing marking lines. By setting up a 1:1 length drawing 2, a wiring harness clamping module 3, and a marking line module 4 on the workbench 1, the device allows for simultaneous marking of the sleeved portions of the wiring harness by the operator twisting it (twisting the harness to rotate it one revolution) at the same workstation. Simultaneously, it allows for dimensional checks of the wiring harness to determine if it is within tolerance limits, reducing material transfers and improving production efficiency. This device not only ensures accurate marking line positioning and wiring harness dimensions but also significantly improves employee work efficiency.

[0028] Furthermore, the wire harness clamping module 3 includes a clamping module body 30, and a car wire harness receiving groove 31 is machined on one side of the clamping module body 30. The part of the car wire harness with a sleeve can enter the car wire harness receiving groove 31 through the open end of the car wire harness receiving groove 31 and rotate in the car wire harness receiving groove 31.

[0029] Specifically, such as Figure 3As shown, in this embodiment, the clamping module body 30 is a square block structure. The clamping module body 30 has a horizontally arranged automotive wiring harness receiving groove 31 on the side facing the operator. The part of the automotive wiring harness with a sleeve can enter the automotive wiring harness receiving groove 31 through the open end of the automotive wiring harness receiving groove 31 and rotate in the automotive wiring harness receiving groove 31. The wiring harness clamping module with this structure not only has the advantages of simple structure, but also convenient operation.

[0030] Furthermore, the opening end of the clamping module body 30 is also provided with a guide surface 32.

[0031] Specifically, in this embodiment, the opening end of the clamping module body 30 is provided with a guide surface 32, so that the opening of the automotive wiring harness receiving groove 31 gradually increases from the inside to the outside, and the opening of the automotive wiring harness receiving groove 31 is an enlarged opening, so that the part of the automotive wiring harness with a sleeve can be easily inserted into the automotive wiring harness receiving groove 31. In this embodiment, the width of the automotive wiring harness receiving groove 31 is slightly larger than the part of the automotive wiring harness with a sleeve, so that the part of the automotive wiring harness with a sleeve can be confined within it and can be rotated by the operator's twisting, thereby causing the marking pen to draw a marking coil on the outer wall of the sleeve by the operator's twisting.

[0032] Furthermore, the marking pen drawing module 4 includes a marking pen clamping block 40 and a locking screw 41;

[0033] The marker pen holder 40 has a through hole 42 for the marker pen 6 to pass through, and the locking screw 41 is provided on the marker pen holder 40 to lock the marker pen 6 that passes through the through hole 42.

[0034] Specifically, such as Figure 3 As shown, in this embodiment, the marking pen drawing module 4 includes a marking pen clamping block 40 and a locking screw 41. The marking pen clamping block 40 is a square block structure with a through hole 42 machined in it. The marking pen 6 can pass through the through hole 42 so that the pen tip faces the part of the automotive wiring harness with a sleeve placed in the wiring harness clamping module 3 and contacts the outer wall of the sleeve. The top of the marking pen clamping block 40 is provided with a threaded hole, and the locking screw 41 is provided in the threaded hole. The end of the locking screw 41 can contact the marking pen that passes through the through hole to fix and lock the marking pen in the marking pen clamping block 40.

[0035] Furthermore, it also includes an automotive wiring harness clamping point module 5, which is set on the table surface of the workbench 1 for fixing one end of the automotive wiring harness.

[0036] Specifically, an automotive wiring harness clamping module 5 is provided at one end of the 1:1 length drawing 2 on the workbench 1. The automotive wiring harness clamping module 5 is provided with an automotive wiring harness sheath receiving groove. The sheath at one end of the automotive wiring harness can be put into the automotive wiring harness sheath receiving groove to fix one end of the automotive wiring harness. This makes it convenient for the operator to straighten the automotive wiring harness so that the automotive wiring harness can be compared with the 1:1 length drawing 2 on the workbench 1 to determine whether the length of the automotive wiring harness meets the requirements.

[0037] Furthermore, both the wire harness clamping module 3 and the marking stroke module 4 have two sets.

[0038] Specifically, in this embodiment, since both the wire harness clamping module 3 and the marking line module 4 have two sets, the wire harness clamping module 3 can effectively clamp (limit) the part of the automotive wire harness with sleeves, thereby facilitating the operator to twist the part of the automotive wire harness with sleeves and make this part rotate in the automotive wire harness receiving groove 31 of the wire harness clamping module 3. With two sets of marking line modules 4, two marking lines can be drawn on the part of the automotive wire harness with sleeves at the same time to meet the process requirements.

[0039] Furthermore, the wire harness clamping module 3 and the marking pen line module 4 are detachably connected to the table surface of the workbench 1.

[0040] Specifically, in this embodiment, the clamping module body 30 is provided with an outwardly protruding fixing part 33 on the side opposite to the open end. The fixing part 33 is provided with a first mounting hole 34. The clamping module body 30 is fixed to the workbench 1 by inserting screws into the first mounting hole 34. The marking pen clamping block 40 is provided with a second mounting hole 43. The marking pen clamping block 40 is fixed to the workbench 1 by inserting screws into the second mounting hole 43. Since the wire harness clamping module 3 and the marking pen drawing module 4 are detachably connected to the workbench 1, different automotive wire harness drawings can be replaced to realize the length inspection and drawing of different automotive wire harnesses.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
