[0002] During factory inspection of the wiring harness for the power battery pack, inspectors will visually observe the outer skin of the wiring harness, or use machine vision to automatically compare and inspect the outer skin of the wiring harness, mainly to detect whether the outer skin of the wiring harness is damaged, cracked or other defects.

Detailed implementation manner

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 to 4 , in the embodiment of the present invention, a wire harness detection device for a power battery pack includes a bottom plate 100, a winding mechanism 400 is arranged on the top surface of the bottom plate 100, and a downward pressing mechanism 300 is arranged in a matching manner with the winding mechanism 400;

[0022] The winding mechanism 400 includes a cylinder 410, and the bottom end of the cylinder 410 is rotatably connected to the top surface of the bottom plate 100. A vertical chute 411 is opened on the inner side wall of the cylinder 410, and a sliding plate 420 is arranged inside the cylinder 410. One end of the sliding plate 420 is slidably clamped inside the chute 411, and the other end of the sliding plate 420 is fixedly connected to a guiding tube 421. A column 430 is fixedly connected to the top surface of the bottom plate 100, and the column 430 is located at the center inside the cylinder 410. A camera module 440 is fixedly connected to the top surface of the sliding plate 420.

[0023] Specifically, by fixing the top of the wire harness, and then passing the wire harness through the inside of the guiding tube 421, so that the whole wire harness is located inside the cylinder 410, and the tail naturally hangs down. Then, by rotating the cylinder 410 and simultaneously sliding down the sliding plate 420, the guiding tube 421 moves synchronously with the sliding plate 420, and the wire harness is wound around the column 430 in a spiral shape. At this time, the surface of the wire harness can be observed through the camera module 440 to check whether there are cracks or other damages on the surface of the wire harness. After the observation is completed, the cylinder 410 can be reversed and the sliding plate 420 can be slid up to reset the wire harness. Then, continue to rotate the cylinder 410 in the reverse direction and slide down the sliding plate 420 at the same time, so that the wire harness is wound around the column 430 in the reverse direction, so that all parts of the wire harness are bent and photographed by the camera module 440, which is convenient for the user to detect the surface of the wire harness.

[0024] Embodiment 1

[0025] AsFigures 1 - 2 As shown, in this embodiment, a motor box 450 is fixedly connected to one side of one arm of the U-shaped frame 200, a driving motor is arranged inside the motor box 450, a gear 451 is fixedly connected to the motor shaft of the driving motor, a plurality of tooth blocks 412 are fixedly connected to the outer side wall of the cylinder body 410, and the gear 451 meshes with the adjacent tooth blocks 412. A sponge cylinder 422 is fixedly sleeved on the inner side wall of the guide pipe 421.

[0026] In this embodiment, by starting the driving motor, the gear 451 can be driven to rotate, so that the gear 451 controls the rotation direction of the cylinder body 410 through the tooth blocks 412. When the wire harness is passed through the guide pipe 421, the wire harness can be closely attached to the inner wall of the sponge cylinder 422, and the sponge cylinder 422 can be closely attached to wire harnesses of different thicknesses through the elasticity of the sponge cylinder 422.

[0027] As Figures 1 - 3 shown, in this embodiment, a U-shaped frame 200 is arranged on the top surface of the bottom plate 100, and both ends of the two arms of the U-shaped frame 200 are fixedly connected to the top surface of the bottom plate 100. A notch is formed on the top surface of the U-shaped frame 200, and the notch is located above the upright column 430. A U-shaped clamping plate 210 is fixedly connected to the top surface of the U-shaped frame 200, and the inside of the U-shaped clamping plate 210 is communicated with the inside of the notch. Both arms of the U-shaped clamping plate 210 are L-shaped, and a clamping plate 220 is arranged in a matching manner with the U-shaped clamping plate 210. A groove is formed on one side of the clamping plate 220, and both arms of the U-shaped clamping plate 210 are respectively slidably clamped at both ends inside the groove. A resisting block 230 is slidably clamped between both arms of the U-shaped clamping plate 210, and one end of the resisting block 230 is rotatably connected to a screw rod 231. A threaded hole is formed on the other side of the clamping plate 220, and the outer side wall of the screw rod 231 is screwed with the inner side wall of the threaded hole.

[0028] During specific implementation, when fixing the head of the wire harness, the clamping plate 220 can be removed from the U-shaped clamping plate 210, and then the head of the wire harness is placed at the notch. Then, the user can clamp the clamping plate 220 on the U-shaped clamping plate 210 to close the U-shaped clamping plate 210 and prevent the wire harness from moving out of the notch. Then, the screw rod 231 is rotated to make the resisting block 230 press against the wire harness to fix the wire harness and prevent the wire harness from rotating or detaching from the notch.

[0029] Embodiment Two

[0030] On the basis of Embodiment One, a pressing mechanism 300 is arranged to control the movement of the sliding plate 420.

[0031] As Figure 1 and Figure 4As shown, in this embodiment, the pressing mechanism 300 includes two electric push rods 310, and the two electric push rods 310 are respectively fixedly connected to the opposite sides of the U-shaped frame 200 through mounting brackets. A snap ring 320 is arranged inside the cylinder body 410, and the movable ends of the two electric push rods 310 are fixedly connected to the top surface of the snap ring 320. A card slot 423 is formed on the top surface of the sliding plate 420, and the snap ring 320 is slidably clamped inside the card slot 423.

[0032] During specific implementation, when the cylinder body 410 rotates, the user can start the two electric push rods 310 to drive the snap ring 320 to move up and down inside the cylinder body 410, so that the snap ring 320 drives the sliding plate 420 to move synchronously. When the cylinder body 410 drives the guide pipe 421 and the wire harness to rotate around the column 430, the spacing of the wire harness wound on the column 430 can be adjusted by the downward movement speed of the snap ring 320. The larger the spacing of the wire harness wound on the column 430, the smaller the bending degree of the wire harness; the smaller the spacing of the wire harness wound on the column 430, the larger the bending degree of the wire harness skin, so as to control the bending degree of the wire harness skin. The two electric push rods 310 do not contact the cylinder body 410, and the rotation of the cylinder body 410 does not affect the electric push rods 310.

Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.

This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
