Description
Technical Field
[0001] This utility model relates to the field of wire harness crimping machines, and in particular to a wire feeding mechanism for a wire harness crimping machine. Background Technology
[0002] A wire harness crimping machine is a high-efficiency device used for the precise connection of wires to terminals or connectors. It is widely used in the automotive, electronics, communications and new energy fields. Its core principle is to use mechanical external force to tightly bond the terminals and wires, forming reliable electrical conduction and mechanical strength, replacing the traditional welding process, and has the advantages of high efficiency and strong stability.
[0003] Before crimping, wire harnesses need to be arranged and cut sequentially. However, the wire harness is in a curled state inside the wire feeding reel, which causes curling stress inside the wire harness and affects the accuracy of subsequent wire harness cutting. There is a problem that a lot of time needs to be spent straightening the wire harness after feeding before crimping, resulting in low production efficiency. To solve this problem, a wire feeding mechanism for a wire harness crimping machine is proposed. Utility Model Content

A first stabilizing wheel 501 and a second stabilizing wheel 502 are respectively arranged on both sides of the connecting plate 5.
[0023] Example 1: Please refer to Figure 1-4 In this embodiment of the utility model, a wire feeding mechanism for a wire harness pressing machine is provided. A separator ring 5031 is provided on the side of the tension wheel 503. A connecting plate 507 is provided at both ends of the tension wheel 503. The connecting plate 507 is connected to the tension wheel 503 by a bearing. A guide post 504 is provided below the connecting plate 507. The lower end of the guide post 504 is connected to the connecting plate 5. The upper end of the guide post 504 passes through the connecting plate 507. A stop block 506 is provided at the upper end of the guide post 504. A spring 505 is provided on the outside of the guide post 504.
[0024] Spring 505 drives tension wheel 503 to move upward continuously. One end of wire harness body 6 is connected to wire feeding wheel, while the other end of wire harness body 6 is clamped by two rollers 4, so that wire harness body 6 is always in a straight state, thereby relieving the curling stress inside wire harness body 6, reducing the occurrence of bending of wire harness body 6, and improving the accuracy of subsequent wire cutting and crimping operations.
[0025] Example 2: Please refer to Figure 1-4 The difference from Embodiment 1 is that the wire harness body 6 passes between the upper and lower rollers 4, and the upper and lower rollers 4 are clamped to the wire harness body 6. Each end of the roller 4 is provided with a column 402, and the roller 4 is connected to the column 402 by a bearing. The column 402 is installed on the workbench 1, and the upper roller 4 is connected to the second motor 401.
[0026] The fixed frame 3 is equipped with a second electric telescopic rod 304 and a third electric telescopic rod 305. The telescopic end of the second electric telescopic rod 304 is connected to the positioning plate 3041, and the telescopic end of the third electric telescopic rod 305 is connected to the cutting blade 3051. The limiting block 301 is equipped with a pressure groove 302 and a blade groove 303. The pressure groove 302 and the blade groove 303 are located directly below the positioning plate 3041 and the cutting blade 3051, respectively. The wire feeder 2 is equipped with a first electric telescopic rod 203. The telescopic end of the first electric telescopic rod 203 is connected to the pressure plate 2031. The worktable 1 is equipped with a lead screw 101. One end of the lead screw 101 is connected to the first motor 102, and the other end of the lead screw 101 passes through the transmission plate 202. The lead screw 101 is threadedly connected to the transmission plate 202.
[0027] When one end of the wire harness body 6 is successively wound around the first stabilizing wheel 501, the tensioning wheel 503, and the second stabilizing wheel 502, and then passes between the two rollers 4, the fixing frame 3, and the wire feeding frame 2, the first electric telescopic rod 203 controls the pressure plate 2031 to descend and fix one end of the wire harness body 6 inside the wire feeding frame 2. Then, the first motor 102 drives the wire feeding frame 2 to move to the predetermined position through the lead screw 101. At this time, the wire feeding frame 2 pulls the wire harness body 6 to move. The moving distance of the wire feeding frame 2 is the length required after the wire harness body 6 is cut. When the wire feeding frame 2 stops, the second electric telescopic rod 304 controls the positioning plate 3041 to descend and press the wire harness body 6 tightly. The third electric telescopic rod 304... 05. Then, control the cutting blade 3051 to descend and cut the wire harness body 6. Then, take out the cut wire harness body 6 and reset the pressure plate 2031, wire feeder 2, positioning plate 3041 and cutting blade 3051. After the wire feeder 2 is reset, the material receiving platform 201 and the side of the limiting block 301 are attached. Finally, the second motor 401 drives the roller 4 to rotate. The roller 4 then drives the wire harness body 6 to move until one end of the wire harness body 6 is inside the wire feeder 2. Repeat the above steps to realize continuous wire feeding and cutting operations of the wire harness body 6, which improves production efficiency. Compared with the traditional method of manually straightening the wire before cutting, it reduces the consumption of manpower and material resources and reduces production costs.
[0028] The working principle of this utility model is as follows:
[0029] When one end of the wire harness body 6 is fixed inside the wire feeder 2 by the pressure plate 2031, the first motor 102 drives the wire feeder 2 to move to the predetermined position through the lead screw 101. At this time, the wire feeder 2 pulls the straight wire harness body 6 to move. The moving distance of the wire feeder 2 is the length required after the wire harness body 6 is cut. Then, the positioning plate 3041 first descends to press the wire harness body 6, and the cutting blade 3051 descends to cut the wire harness body 6. Then, the cut wire harness body 6 is taken out, and the pressure plate 2031, the wire feeder 2, the positioning plate 3041 and the cutting blade 3051 are reset. Finally, the second motor 401 drives the roller 4 to rotate, and the roller 4 drives the wire harness body 6 to move until one end of the wire harness body 6 is inside the wire feeder 2. By repeating the above steps, the continuous wire feeding and cutting operation of the wire harness body 6 can be realized.
