Then, the cables are assembled into the electronic product so that the terminals at both ends of the cables can be installed in the corresponding positions of the electronic product.

[0004] However, this method of manually picking up the cables one by one and transporting them to the cable assembly station is usually inefficient and easily affects the cable assembly efficiency. Utility Model Content

[0044] Reference Figure 3 The detection component 25 includes a detection source and a support cylinder 252. The support cylinder 252 is fixedly mounted on the side wall of the straightening support plate 21 and is located below the lower slide 243. The piston rod of the support cylinder 252 extends downwardly from the slide 243. The detection source is a pressure sensor 251.

The pressure detection by the pressure sensor 251 and the external control system are both existing technologies in the art and will not be described in detail here.

[0045] In another embodiment of the present application, the detection source can also be a visual camera, which is installed on the side wall of the straightening support plate 21, and the input end of the visual camera is facing the cable between the upper clamping member 23 and the lower clamping member 24, and the visual camera is used to take pictures to detect the straightening state of the cable. The specific visual camera and the visual camera's photo detection of the cable are existing technologies in this field and will not be elaborated here. In another embodiment of the present application, the detection source can also be an external power supply, by energizing the upper electric clamp 231 in the upper clamping member 23 and the lower electric clamp 241 in the lower clamping member 24. When the cable is straightened, the upper electric clamp 231 and the lower electric clamp 241 are connected. When the cable is not straightened, the upper electric clamp 231 and the lower electric clamp 241 are not connected, thereby judging whether the cable is straightened.

[0046] The working principle of the embodiment of the present application is as follows: when the cables are in a dispersed state after being processed by the branching mechanism 4, the cables in the branching mechanism 4 need to be transported one by one to the next process through the harness unloading mechanism. At this time, the transfer motor 31 in the transfer assembly 3 drives the straightening support plate 21 to rotate to a vertical state, so that the upper clamping member 23 and the lower clamping member 24 on the straightening support plate 21 are sent to the cables in the branching mechanism 4, and at this time, the upper clamping member 23 is driven by the straightening member 22 to move to the lower clamping member 24, so that the upper clamping member 23 and the lower clamping member 24 are fitted together, and then the upper clamping cylinder 232 and the lower clamping cylinder 242 are respectively driven to drive the upper electric clamping claw 231 and the lower clamping claw 24. When the lower electric clamp 241 moves toward the line-dividing mechanism 4 to the cable, and the upper electric clamp 231 and the lower electric clamp 241 begin to move toward the line-dividing mechanism 4, the upper electric clamp 231 drives the first upper clamping part 2311 and the second upper clamping part 2312 to open, and the lower electric clamp 241 drives the first lower clamping part 2411 and the second lower clamping part 2412 to open, thereby facilitating the upper electric clamp 231 and the lower electric clamp 241 to clamp the cable.

[0047] When the upper clamping member 23 and the lower clamping member 24 move to the cable in the branching mechanism 4, the limiting rod 27 in the upper clamping member 23 contacts the side wall of the cable, so that the cable is always in the upper clamping groove 2313 of the upper clamping member 23, and the metal terminal at the upper end of the cable is located above the upper clamping member 23, and then the upper clamping member 23 and the lower clamping member 24 contract, so that the metal terminal at the upper end of the cable contacts the top wall of the upper clamping groove 2313 formed by the first upper clamping part 2311 and the second upper clamping part 2312 in the upper clamping member 23, and the cable can slide in the upper clamping groove 2313. Then, the straightening motor 221 drives the straightening drive wheel 222 to rotate, causing the straightening drive wheel 222 to drive the straightening transmission wheel 223 to rotate via the straightening synchronous belt 224, thereby causing the straightening synchronous belt 224 to drive the upper slide 233 to move upward, thereby driving the upper clamping member 23 to move upward, causing the upper clamping member 23 to drive the metal terminal of the cable to move upward, thereby pulling the cable upward, so that the cable is gradually straightened. At this time, the support cylinder 252 supports the lower slide 243, thereby offsetting the gravity of the lower clamping member 24 on the lower slide 243, so that the value detected by the pressure sensor 251 is a stable value.

[0048] Then, as the straightening member 22 drives the upper clamping member 23 to move upward until the cable is straightened, the metal terminal at the lower end of the cable contacts the bottom wall of the lower clamping groove 2413 formed between the first lower clamping portion 2411 and the second lower clamping portion 2412 in the lower clamping member 24, so that the upper clamping member 23 pulls the lower clamping member 24 upward through the cable, thereby causing the value in the pressure sensor 251 to change. At this time, the external control system detects the change in the value in the pressure sensor 251, thereby determining that the cable has been straightened, and sending a stop action instruction to the straightening member 22, so that the cable is no longer straightened. Then the transfer motor 31 drives the straightening support plate 21 to rotate a certain angle, so that the metal terminal at the lower end of the cable moves out of the branching mechanism 4.

[0049] Then, the upper clamping cylinder 232 pulls the upper electric clamping jaw 231 to move in the direction of the straightening support plate 21, so that the upper electric clamping jaw 231 drives the upper end of the cable to move in the direction of the straightening support plate 21, thereby causing the upper electric clamping jaw 231 to move relative to the upper push rod 26, so that the upper push rod 26 gradually extends into the upper clamping groove 2313 on the upper electric clamping jaw 231, so that the end of the upper push rod 26 hits the side wall of the metal terminal at the upper end of the cable, thereby pushing the metal terminal at the upper end of the cable to the end of the upper clamping groove 2313. At the same time, the lower clamping cylinder 24 The lower electric clamping jaw 241 is pulled toward the straightening support plate 21, thereby causing the lower electric clamping jaw 241 to be displaced relative to the lower push rod 28, causing the lower push rod 28 to gradually extend into the lower clamping groove 2413 on the lower electric clamping jaw 241, so that the end of the lower push rod 28 abuts against the side wall of the metal terminal at the lower end of the cable, thereby pushing the metal terminal at the lower end of the cable to the end of the lower clamping groove 2413, so that the cable is parallel to the axis of the straightening support plate 21. In this process, the straightening member 22 fine-tunes the position of the upper clamping member 23, so that the cable remains in a taut state.

[0050] Then the upper electric clamp 231 continues to drive the first upper clamping part 2311 and the second upper clamping part 2312 to further perform the clamping action, thereby clamping the upper end of the cable, so that the upper end of the cable remains in a positioned state on the upper electric clamp 231. At the same time, the lower electric clamp 241 continues to drive the first lower clamping part 2411 and the second lower clamping part 2412 to continue clamping, thereby clamping the lower end of the cable, thereby positioning the lower end of the cable in the lower electric clamp 241. Then, the upper clamping part 23 is driven to drop a certain distance by the straightening part 22, so that the cable is slightly bent, so that the terminals at both ends of the cable are kept in a constant position, so that it can adapt to cables of different lengths, and it is convenient to keep the metal terminals of the cable in the working position in the next process when the straightening support plate 21 is driven by the transfer motor 31 to rotate to the next process.

[0051] The above are preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
