[0001] This utility model relates to the technical field of wire feeding devices, specifically a wire feeding device for automotive wire harness processing. Background Technology

[0002] Automotive wiring harnesses are a crucial component of the electrical system in modern vehicles, carrying electrical signals and transmitting power. With the increasing electrification and intelligence of automobiles, the functions and quantity of wiring harnesses are gradually increasing, leading to ever-rising precision machining requirements. This necessitates the use of wire-laying devices during processing. However, an existing wire-laying device for automotive wiring harness processing (Announcement No.: CN218732323U) has the following drawbacks in use:

[0003] When processing a wire harness, after the current harness is finished, the next wire harness needs to be processed. The operator needs to manually remove the storage rack on the wire reel and place the next storage rack with the wire harness wound on it for the next processing. This requires manual handling by the operator, which is labor-intensive and inconvenient. Therefore, this patent proposes a wire feeding device for automotive wire harness processing to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a wire feeding device for automotive wiring harness processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wire feeding device for automotive wiring harness processing, comprising a base plate, a support frame fixed to the top of the base plate, a turntable rotatably connected to the inner wall of one end of the support frame, a plurality of feeding rollers rotatably connected to one side of the turntable, a feeding mechanism provided at the top of the base plate, the feeding mechanism comprising a first limiting frame and a second limiting frame fixed to the top of the base plate, a feeding plate slidably connected between the first limiting frame and the second limiting frame, a connecting frame fixed to one side of the first limiting frame, a first cylinder fixed to one end of the connecting frame, the output end of the first cylinder being fixed to the feeding plate, a support seat fixed to the top of the base plate, a feeding mechanism provided on the support seat, the feeding mechanism comprising a first rack fixed to the bottom end of the feeding plate, a gear rotatably connected to the top of the support seat, a second rack slidably connected to the top of the support seat, the first rack and the second rack meshing with the gear, and a feeding rod fixed to one side of the second rack.

[0007] Preferably, the top of the support frame is fixedly connected to a discharge box, and the discharge box is fixed to the first limiting frame and the second limiting frame.

[0008] Preferably, a second cylinder is fixed to the inner wall of the other end of the support frame, and the output end of the second cylinder is rotatably connected to a limit plate.

[0009] Preferably, a fixing frame is fixed to the top of the base plate, a first rotating wheel is rotatably connected to one end of the fixing frame, and a second rotating wheel is provided at one end of the fixing frame.

[0010] Preferably, one end of the fixing frame is provided with an installation groove, a lead screw is rotatably connected in the installation groove, a slider is screwed to the outer wall of the lead screw, and one end of the slider is rotatably connected to the second rotating wheel.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By driving a turntable to rotate, which in turn drives multiple feeding rollers to rotate, and multiple storage racks are inserted into the feeding rollers, the wire harness is wound on the storage racks. After the wire harness is processed, the storage rack needs to be removed, and then the next storage rack containing the wire harness is placed on it to complete the feeding process. In this process, by activating the first cylinder, the first cylinder drives the feeding plate to move forward, thereby pushing the storage racks in the first and second limit frames to move, so that the storage racks are inserted into one of the feeding rollers.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Automotive wiring harnesses are an important component of the electrical system in modern vehicles, carrying electrical signals and power transmission. With the increasing electrification and intelligence of automobiles, the functions and quantity of wiring harnesses are gradually increasing, leading to ever-higher precision machining requirements, necessitating the use of wire-laying devices during the manufacturing process.

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: a wire feeding device for automotive wiring harness processing, including a base plate 1, a support frame 2 fixed to the top of the base plate 1, a turntable 3 rotatably connected to the inner wall of one end of the support frame 2, a plurality of feeding rollers 7 rotatably connected to one side of the turntable 3, and a feeding mechanism 8 provided at the top of the base plate 1. Both the turntable 3 and the feeding rollers 7 can be driven to rotate by existing drive devices, which is prior art and will not be elaborated upon here. The feeding mechanism 8 includes a first limiting frame 801 and a second limiting frame 802 fixed to the top of the base plate 1, and a feeding plate 80 is slidably connected between the first limiting frame 801 and the second limiting frame 802. 3. A connecting frame 804 is fixed to one side of the first limiting frame 801. A first cylinder 805 is fixed to one end of the connecting frame 804. The output end of the first cylinder 805 is fixed to the feeding plate 803. A support base 13 is fixed to the top of the base plate 1. A feeding mechanism 9 is provided on the support base 13. The feeding mechanism 9 includes a first rack 901 fixed to the bottom end of the feeding plate 803. A gear 902 is rotatably connected to the top end of the support base 13. A second rack 903 is slidably connected to the top end of the support base 13. The first rack 901 and the second rack 903 mesh with the gear 902. A feeding rod 904 is fixed to one side of the second rack 903. The feeding mechanism 8 also includes a limiting plate 806 fixed to the top end of the feeding plate 803.

[0021] It should be noted that by driving the turntable 3 to rotate, the turntable 3 drives multiple feeding rollers 7 to rotate. Multiple storage racks are inserted into the feeding rollers 7. The wire harness is wound on the storage racks. After the wire harness is processed, the storage rack needs to be removed, and then the next storage rack containing the wire harness is placed to complete the feeding process. During this process, by activating the first cylinder 805, the first cylinder 805 drives the feeding plate 803 to move forward, thereby pushing the storage racks in the first limit frame 801 and the second limit frame 802 to move, so that the storage rack inserts into one of the feeding rollers. On 7, when the feeding plate 803 moves, the first rack 901 moves, which drives the gear 902 to rotate. The gear 902 rotates, which drives the second rack 903 to move. The second rack 903 moves, which drives the unloading rod 904 to move, pushing the storage rack on the other unloading roller 7 off the unloading roller 7 to achieve unloading. After that, the first cylinder 805 drives the feeding plate 803 to return to its original position. Compared with the existing method that requires manual material handling, this method is easier to operate and does not require much effort to move the wire harness.

[0022] like Figure 1 and Figure 2 As shown, a discharge box 12 is fixedly connected to the top of the support frame 2, and the discharge box 12 is fixed to the first limiting frame 801 and the second limiting frame 802. A second cylinder 10 is fixed to the inner wall of the other end of the support frame 2, and the output end of the second cylinder 10 is rotatably connected to the limiting plate 11. A fixing frame 4 is fixed to the top of the base plate 1, and a first rotating wheel 5 is rotatably connected to one end of the fixing frame 4, and a second rotating wheel 6 is provided at one end of the fixing frame 4. An installation groove is opened at one end of the fixing frame 4, and a lead screw is rotatably connected in the installation groove. A slider is screwed to the outer wall of the lead screw, and one end of the slider is rotatably connected to the second rotating wheel 6.

[0023] It should be noted that the discharge box 12 contains multiple storage racks with wire harnesses wound inside. When the first cylinder 805 moves the feeding plate 803 forward, the limiting plate 806 moves forward to block the discharge port of the discharge box 12, preventing the storage racks above from falling. When the feeding plate 803 returns to its original position, the discharge port is no longer blocked, and the next storage rack falls from the discharge port into the space between the first limiting frame 801 and the second limiting frame 802, facilitating the next feeding. By activating the second cylinder 10, the second cylinder 10 drives the limiting plate 11 to... The material storage rack on the feeding roller 7 clamps the material to prevent it from falling. In addition, the height of the second rotating wheel 6 can be adjusted to facilitate the adjustment of the feeding height of the wire harness. In this solution, the electrical components are controlled by their matching peripheral controller. The control circuit can be implemented by simple programming by those skilled in the art. It is common knowledge in the field and is only used without modification. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
