[0035] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0036] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. Conversely, when an element is said to be "directly on" another element, there is no intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0038] like Figures 1 to 5 As shown, a feeding device for a wire harness crimping machine is characterized by comprising a material rack 1 for placing empty wire rods, wherein the wire rods are provided with a plurality of slots.

[0039] Fixing structure 2 is used to fix the wiring rod.

[0040] The wire shifting structure 3 is used to move the crimped terminal wire to the wiring rod position and insert the terminal wire into the slot of the wiring rod.

[0041] The discharge structure 4 is equipped with a discharge trough for placing the wiring rod with the terminal wires plugged in.

[0042] The movable structure 5 is used to move the empty wiring bar to the fixed structure 2 position and move the wiring bar with the terminal wire inserted at the fixed structure 2 position to the discharge structure 4 position.

[0043] After the terminal wires are crimped and formed, the terminal wires are moved to the wiring rod slot at the assembly bar 21 position by the wire shifting structure 3. At this time, the empty wiring rods are placed by the material rack 1, and then the empty wiring rods are moved to the assembly bar 21 position by the action of the moving structure 5. After the terminal wires are inserted, the wiring rods are moved to the discharge structure 4 position by the moving structure 5 and then taken out. In this process, the fully automatic loading and unloading of wiring rods and the fully automatic insertion process of terminal wires are realized, which can improve production efficiency. The terminal wires are neatly arranged on the wiring rods, which is convenient for subsequent production processes.

[0044] At this time, the empty wiring bar is placed at the material rack 1 position, and needs to work together with the moving structure 5 to realize the automatic feeding process of the wiring bar. Therefore, in this embodiment, the material rack 1 includes an inclined storage plate 11, and a transfer block 12 is provided at the lower position of the storage plate 11. The transfer block 12 is provided with a vertical groove 121, and an arc surface 122 is provided on one side of the vertical groove 121. The arc surface 122 and the bottom of the storage plate 11 form a smooth surface. The storage plate 11 is tilted, allowing the wiring rod located on the upper side of the storage plate 11 to slide downwards under gravity. To catch the sliding wiring rod, a transition block 12 is provided at a lower position on the storage plate 11. The transition block 12 has a corresponding vertical groove 121 to catch the sliding wiring rod. To make the wiring rod slide more smoothly, the side of the vertical groove 121 has an arc surface 122, which forms a smooth surface with the bottom of the storage plate 11. That is, the wiring rod can smoothly slide from the bottom of the storage plate 11 through the arc surface 122 into the vertical groove 121. At the same time, when the wiring rod slides to the vertical groove 121 on the upper side of the storage plate 11, the wiring rod changes from a tilted state to a vertical state, so that the slot of the wiring rod is located on the upper side. When it moves to the fixed structure 2, the slot of the wiring rod is also facing upwards, making it convenient to insert the terminal wire into the slot of the wiring rod.

[0045] The wiring rod on the upper side of the storage plate 11 moves because the storage plate 11 is tilted. At this time, in order to control the moving speed of the wiring rod during the movement, it is necessary to control the tilt angle of the storage plate 11. Specifically, in this embodiment, the storage plate 11 is rotatably connected to the adapter block 12. The lower side of the storage plate 11 is also provided with a tilting cylinder 13. The cylinder body of the tilting cylinder 13 is fixed by a bracket. The piston rod of the tilting cylinder 13 is rotatably connected to the bottom of the storage plate 11 through a ball shaft, which is used to control the relative rotation between the storage plate 11 and the adapter block 12. The storage plate 11 is rotatably connected to the adapter block 12 at a lower position via a rotating shaft. As the storage plate 11 rotates, it remains relatively level with the arc-shaped surface 122 of the adapter block 12, thus not affecting the sliding process of the wiring bar. The cylinder body of the tilting cylinder 13 is fixed to the frame of the device and is rotatably fixed. The piston rod of the tilting cylinder 13 is fixed to the bottom of the storage plate 11 via a ball joint. When the piston rod of the tilting cylinder 13 extends or retracts, the storage plate 11 rotates around the lower rotating shaft, allowing the sliding speed of the wiring bar on the upper side of the storage plate 11 to be adjusted, thereby controlling the time it takes for the wiring bar to enter the adapter block 12.

[0046] Since multiple wiring rods are installed on the upper side of the storage bar, in order to maintain a certain production rhythm, the wiring rods need to slide into the vertical slot 121 of the transfer block 12 one by one at a certain frequency. Therefore, at this time, a limiting cylinder 14 is provided on the lower side of the storage plate 11. The piston rod of the limiting cylinder 14 is connected to a limiting rod 15. The end of the limiting rod 15 passes through the storage plate 11 to the upper side of the storage plate 11. Under the action of the limiting cylinder 14, the limiting rod 15 protrudes from the upper side of the storage plate 11 or moves to the lower side of the storage plate 11, thereby forming a blocking structure for the wiring rods. In this way, by controlling the action of the limiting rod 15, only the wiring rod at the bottom position moves into the vertical slot 121 of the transfer plate each time. The remaining wiring rods cannot move downward under the action of the limiting rod 15, thereby ensuring that the wiring rods slide into the vertical slot 121 of the transfer block 12 one by one at a certain frequency.

[0047] The fixing structure 2 is used to fix the wiring rod. After the empty wiring rod is fixed by the fixing structure 2, the crimped terminal wire is moved to the wiring rod at the position of the fixing structure 2 by the wire-moving structure 3, thus completing the insertion of the terminal wire into the slot of the wiring rod. Specifically, the fixing structure 2 includes an assembly strip 21, with a horizontally arranged assembly groove 22 on its upper side. Clamping structures 23 are provided at both ends of the assembly strip 21 to clamp the wiring rod at the position of the assembly groove 22. Further, the clamping structure 23 includes a clamping cylinder 231, with a clamping block 232 on the piston rod of the clamping cylinder 231. The clamping block 232 is spaced a certain distance from the end of the assembly strip 21. The length of the assembly strip 21 is less than the overall length of the wiring rod. Under the action of the moving structure 5, the wiring rod is moved to the position of the assembly groove 22 of the assembly strip 21, and then both ends are clamped by the clamping blocks 232 of the clamping cylinder 231, thus fixing the wiring rod during the terminal wire insertion process and ensuring the terminal wire insertion effect.

[0048] The moving structure 5 is used to move the wiring bar, including moving the empty wiring bar from the position of the adapter block 12 to the position of the assembly slot 22 of the assembly strip 21, and also moving the wiring bar with the terminal wire inserted from the position of the assembly slot 22 of the assembly strip 21 to the position of the discharge slot of the discharge structure 4. Specifically, the moving structure 5 includes a longitudinal moving plate 51, which is fixed to the base plate by a guide rail slider structure. The upper side of the base plate is provided with a longitudinal cylinder 52 for controlling the movement of the longitudinal moving plate 51. Vertical cylinders 53 are respectively provided at both ends of the longitudinal moving plate 51. The piston rod of the vertical cylinder 53 is connected to an upper moving plate 54. The upper side of the upper moving plate 54 is provided with a first moving block 55 and a second moving block 56. The first moving block 55 and the second moving block 56 are spaced apart. The first moving block 55 moves the wiring bar from the position of the material rack 1 to the position of the fixed structure 2, and the second moving block 56 moves the material rack 1 with the terminal wire inserted to the position of the discharge structure 4. Under the action of the longitudinal cylinder 52, the longitudinal moving plate 51 moves longitudinally, which allows the first moving block 55 to move longitudinally between the transition block 12 and the assembly strip 21, and the second moving block 56 to move longitudinally between the assembly strip 21 and the discharge chute. Then, under the action of the vertical cylinder 53, the first moving block 55 and the second moving block 56 move up and down, thereby completing the movement of the wiring bar. At this time, by controlling the synchronous movement of the first moving block 55 and the second moving block 56 through the longitudinal cylinder 52, the empty wiring bar can move from the transition block 12 to the position of the assembly strip 21, and the assembly strip 21 after the terminal wire is inserted can move to the position of the discharge chute simultaneously. At this time, only one longitudinal cylinder 52 is needed to control the movement of two different workstations. The overall structure is relatively simple, reducing equipment costs. At the same time, the efficiency of the wiring bar during movement is also high.

[0049] The two ends of the wiring rod are engaged by the first moving block 55 or the second moving block 56 and then moved. To ensure that the wiring rod does not fall out during the movement, in this embodiment, the first moving block 55 and the second moving block 56 are provided with limiting grooves 57, and the outer side of the limiting grooves 57 is provided with side baffles 58. By setting the limiting grooves 57 and the outer side baffles 58, the wiring rod can be limited. In this way, the two ends are stably engaged by the first moving block 55 or the second moving block 56 during the movement of the wiring rod. At the same time, in order to ensure that the first moving block 55 and the second moving block 56 can smoothly move the wiring rod out from the position of the adapter block 12, the first moving block 55 and the second moving block 56 are located on the outer side of the adapter block 12. In addition, in order to ensure that the wiring rod can be moved in and out of the assembly strip 21, the first moving block 55 and the second moving block 56 are located between the assembly strip 21 and the clamping block 232.

[0050] The wire-shifting structure 3 is used to move the crimped terminal wire and insert it into the slot of the wiring rod. In this embodiment, the wire-shifting structure 3 includes a horizontal support 31, a horizontal module 32 on the side of the horizontal support 31, a horizontal moving plate 33 at the moving end of the horizontal module 32, and a vertical moving cylinder 34 at the lower side of the horizontal moving plate 33. The piston rod of the vertical moving cylinder 34 is connected to a finger cylinder 35 through a connecting plate, and the moving end of the finger cylinder 35 is provided with a gripper 36. Under the action of the horizontal module 32, the horizontal moving plate 33 moves horizontally, and under the action of the vertical moving cylinder 34, the finger cylinder 35 moves vertically, so that the finger cylinder 35 can move horizontally and vertically. Then, the terminal wire is clamped and moved by the gripper 36 of the finger cylinder 35, thereby completing the movement of the crimped terminal wire.

[0051] In another embodiment, a wire harness crimping and blanking method is included, specifically comprising:

[0052] Place the empty wiring rod on the outside of the inclined storage plate 11;

[0053] If there is a wiring rod at the position of the vertical slot 121 of the adapter block 12, if not, control the storage plate 11 to rotate to the preset angle position, and control the wiring rod to slide from the side of the storage plate 11 to the position of the vertical slot 121 of the adapter block 12.

[0054] The first moving block 55 of the control moving structure 5 moves the wiring bar at the position of the transfer block 12 to the position of the assembly groove 22 of the assembly strip 21. At the same time, if there is a wiring bar at the position of the assembly groove 22 of the assembly strip 21, the second moving block 56 of the moving structure 5 moves the original wiring bar to the position of the discharge groove of the discharge structure 4.

[0055] The fixing structure 2 fixes both ends of the wiring rod, thereby fixing the wiring rod in the position of the assembly slot 22;

[0056] The movable structure 5 moves to the initial position, specifically the first movable block 55 moves to the position aligned with the transition block 12, and the second movable block 56 moves to the position aligned with the assembly slot 22;

[0057] The wire shifting structure 3 inserts the crimped terminal wire into the wiring bar at position 22 of the assembly slot.

[0058] After the terminal wire is formed by crimping, the terminal wire is moved to the wiring rod slot at the assembly bar 21 by the wire moving structure 3. At this time, the empty wiring rod is placed by the material rack 1, and then the empty wiring rod is moved to the assembly bar 21 by the action of the moving structure 5. After the terminal wire is inserted, the wiring rod is moved to the discharge structure 4 by the moving structure 5 and then taken out. In this process, the fully automatic loading and unloading of wiring rods and the fully automatic insertion process of terminal wires are realized, thereby improving production efficiency. The terminal wires are neatly arranged on the wiring rods, which facilitates subsequent production processes.

[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
