Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicle wire harness production, in particular to a wire unwinding device for new energy vehicle wire harness production. Background Technique

[0002] Many devices in the production process of new energy vehicle wire harnesses use various wire unwinding devices. These devices help improve production efficiency, ensure the quality of wire harness processing, and achieve automated production. The following are some common machines using wire unwinding devices in new energy vehicle wire harness production, including wire opening machines, winding machines, and wire stripping machines, etc. The winding machine is used to wind protective materials outside the wire harness. For example, there are plastic connectors at both ends of some automotive wire harnesses, and there are multiple strands of wire harnesses connected between the two connectors, which need to be wound outside for fixation and protection. In some factories with relatively low automation levels, when winding the wire harness, workers hold the wire harness horizontally and put it into the winding machine, and move it horizontally for winding. However, it is difficult for workers to keep the wire harness as straight as possible and move the wire harness smoothly horizontally, which is also labor-consuming. As a result, the wire harness is not wound evenly, and some inner cores are exposed. At the same time, manual operation is somewhat dangerous. The setting of the protective shell outside the winding machine is to play a certain protective role because the internal components of the winding machine rotate at high speed, and when there is a misoperation, it will still impact the worker's hand, making it inconvenient to use.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model

[0020] Please refer to Figures 1 to 4 , in the embodiment of the present utility model, a wire pay-off device for the production of new energy vehicle wiring harnesses includes a wire pay-off mechanism 10. The wire pay-off mechanism 10 includes a base 11 and a U-shaped frame 14. A limit frame 12 is slidably connected to the top of the base 11. An L-shaped frame 121 is slidably connected to the top of the limit frame 12. A rectangular shell 13 is fixedly connected to the front end of the L-shaped frame 121. Two support arms 131 are rotatably connected to the top of the rectangular shell 13. A limit rod 132 is fixedly connected to the bottom of the front end of the support arm 131. Both limit rods 132 are rotatably connected to the U-shaped frame 14. Fixed blocks 141 are fixedly connected to both sides of the U-shaped frame 14. Two support blocks 142 are slidably connected to the bottom of the U-shaped frame 14. A drive module 17 for driving the two support arms 131 to rotate synchronously is arranged inside the rectangular shell 13

[0021] Specifically, a U-shaped frame 14 is rotatably connected between the bottom ends of the two limit rods 132. Workers place the two ends of the wire harness on the tops of adjacent support blocks 142 respectively. The fixed blocks 141 prevent the wire harness from detaching and tighten the wire harness. Start the motor 123 to horizontally wind the wire harness through the winding unit body 20. Move at a constant speed to make the wire harness wind smoothly and evenly. Start the hydraulic rod 111 to make the U-shaped frame 14 contact the regulating frame 151 to drive the support block 142 to move, and automatically blank the packaged wire harness, saving manpower and being convenient to use

[0022] Example 1

[0023] As Figures 1 - 2 shown, in this embodiment, two hydraulic rods 111 are fixedly connected to the top of the base 11. The output end of the hydraulic rod 111 is fixedly connected to the limit frame 12. A one-way lead screw 122 is rotatably connected inside the limit frame 12. The one-way lead screw 122 penetrates through the L-shaped frame 121 and is in threaded connection with it. A motor 123 is fixedly connected to the outer wall of one end of the limit frame 12. The output end of the motor 123 penetrates through the limit frame 12 and is fixedly connected to the adjacent end of the one-way lead screw 122. A plurality of rollers 1211 are rotatably connected to the bottom of the L-shaped frame 121.

[0024] In this embodiment, the limit frame 12 is slidably limited by the base 11. By synchronously starting the two hydraulic rods 111, the limit frame 12 can be driven to move, driving the C-shaped frame 14 and the regulation frame 151 closer, thereby driving the two support blocks 142 to move to cut the wire harness. When the C-shaped frame 14 contacts the regulation frame 151, the wire harness is above the blanking frame 15, and the wire harness will fall on the inclined surface of the blanking frame 15 and slide automatically for collection. The L-shaped frame 121 is slidably limited by the limit frame 12, so that the L-shaped frame 121 can move horizontally to drive the C-shaped frame 14 to transfer. Starting the motor 123 can drive the one-way lead screw 122 to rotate, thereby driving the L-shaped frame 121, the rectangular shell 13 and its upper components to move horizontally. A device with a certain weight is fixed at the front end of the L-shaped frame 121. Through the setting of the rollers 1211, it is convenient to reduce the friction between the L-shaped frame 121 and the limit frame 12, making the overall movement of the L-shaped frame 121 smoother.

[0025] As Figure 4 shown, in this embodiment, a blanking frame 15 and a workbench 16 are arranged on the front side of the base 11. A collection cabinet 152 is movably clamped at the front end of the blanking frame 15. Connecting rods 143 are fixedly connected to both sides of the C-shaped frame 14. One end of the connecting rod 143 is fixedly connected to the adjacent fixed block 141. A first rack 1421 is fixedly embedded at the top of the support block 142. Two second racks 144 are slidably connected inside the C-shaped frame 14. A spring 145 is fixedly connected between one end of the second rack 144 and the C-shaped frame 14. Two circular gears 146 are rotatably connected inside the C-shaped frame 14. The second rack 144 and the first rack 1421 are both meshed with the adjacent circular gear 146. A regulation frame 151 for driving the second rack 144 is fixedly connected to the top of the blanking frame 15.

[0026] During specific implementation, the workbench 16 is provided for the staff to load the U-shaped frame 14. The unloading rack 15 is used to guide the wound wire harness in the U-shaped frame 14 to the inside of the collection cabinet 152 for collection. After the L-shaped frame 121 horizontally moves through the U-shaped frame 14 to drive the wire harness to pass through the winding unit body 20 for winding, the L-shaped frame 121 continues to move to one end of the limit frame 12. Then, two hydraulic rods 111 are synchronously started to push the limit frame 12 to move, so that the U-shaped frame 14 moves forward. The outer ends of the two second racks 144 are in contact with the regulation frame 151. The regulation frame 151 pushes the second rack 144 to move. The second rack 144 drives the circular gear 146 to rotate. Through the transmission of the circular gear 146 and the first rack 1421, the support block 142 is driven to move. The support block 142 completely moves below the U-shaped frame 14. Without the support of the support block 142, the wire harness falls into the unloading rack 15 for collection.

[0027] Embodiment 2

[0028] On the basis of Embodiment 1, in order to be able to drive the two support arms 131 to rotate synchronously, during the transfer process of the U-shaped frame 14, the U-shaped frame 14 is always flush with the rectangular shell 13, which is convenient for horizontally passing the wire harness through the winding unit body 20 for winding processing.

[0029] As Figures 1 - 3 shown, in this embodiment, the driving module 17 includes a second motor 174 fixedly connected to the inner bottom surface of the rectangular shell 13. Conical gears 171 are fixedly sleeved on the outer walls of the support arms 131. One of the two conical gears 171 faces directly upward and the other faces directly downward. Two shaft rods 172 are symmetrically and rotatably connected to the inner bottom surface of the rectangular shell 13. A conical gear 173 is fixedly sleeved at one end of the shaft rod 172. The conical gear 173 meshes with the adjacent conical gear 171. Both output ends of the second motor 174 are fixedly connected to the adjacent shaft rod 172.

[0030] During specific implementation, starting the second motor 174 can synchronously drive the two shaft rods 172 and the conical gears 173 to rotate. Through the transmission of the conical gears 173 and the conical gears 171, the two support arms 131 rotate synchronously in the same direction. Combined with the rotational connection between the U-shaped frame 14 and the limit rod 132, the U-shaped frame 14 is always parallel to the rectangular shell 13 during the movement process, which is convenient for transferring the wire harness.
