Description

Technical Field

[0001] The present application relates to the field of automated production, and more particularly to a feeding device for flexible wire harnesses. Background Art

[0002] With the rapid development of industries such as electronics, automotive, and communication, the demand for flexible wire harnesses is increasing day by day. As an important component connecting various electronic components or modules, the quality and production efficiency of flexible wire harnesses directly affect the performance and cost of the final products. Therefore, how to improve the production efficiency and feeding accuracy of flexible wire harnesses has become the focus of manufacturers. During the production process of wire harnesses, it is necessary to insert and assemble sheaths or injection molded parts with the wire harnesses. Therefore, the transportation and positioning of injection molded parts are very important. However, the existing feeding mechanisms mainly wind and wrap the wire harnesses themselves and cannot effectively position the injection molded parts.

[0003] For example, in the patent with the application number CN202120757309.0, a feeding device for wire harness production, the following deficiencies exist in the actual use process of the above patent:

[0004] This device collects the material wire harness through a receiving plate, and then multiple rotating shafts rotate to bend and guide the wire harness, so that multiple wires are wound to form a wire harness body. However, during the subsequent overall assembly of the wire harness, there is a lack of feeding and positioning operations for sheaths and injection molded parts. It is necessary for workers to pick up the sheaths and insert them into the wire harness body, which increases the processing cost and cannot achieve automated production. Summary of the Utility Model

[0005] In order to improve the problem that the conventional wire harness feeding device lacks feeding and positioning operations for the protective sleeve parts, resulting in incomplete automated production and increased processing costs, the present application provides a feeding device for flexible wire harnesses.

[0006] The feeding device for flexible wire harnesses provided by the present application adopts the following technical solutions:

[0007] A feeding device for flexible wire harnesses includes a main base. A moving groove is formed on one side of the top of the main base, and a moving seat for transporting materials is movably arranged in the moving groove.

[0008] The feeding mechanism includes a moving mechanism arranged on the top of the main base on the side of the moving seat. A lead screw inside the moving mechanism is connected to a U-shaped feeding plate. A plurality of negative pressure suction ports for adsorbing materials are arranged on the surfaces of both U-shaped ends of the feeding plate, and the left U-shaped end of the feeding plate is aligned with the moving seat.

[0009] On one side of the moving groove at the top of the main base, a positioning seat is provided. The top of the positioning seat is aligned with the right U-shaped end of the feeding plate. On the outer side of one side of the main base where the positioning seat is located, a plurality of storage bins are rotatably arranged. One of the plurality of storage bins close to the positioning seat is linearly aligned with the positioning seat and the moving seat respectively.

[0010] By adopting the above technical solution, the moving mechanism drives the feeding plate to move, and cooperates with the negative pressure suction port to adsorb the injection molding material at the right end of the bottom of the feeding plate, so as to drive the injection molding material to move into the positioning seat for auxiliary positioning. Then, as the right end of the feeding plate adsorbs the injection molding material, the left end of the feeding plate adsorbs the injection molding material in the positioning seat and moves it into the moving seat, thus completing the placement of the injection molding material. Then, the moving seat moves along the moving groove to complete the transportation of the material, while positioning the injection molding material, the whole process is automated production.

[0011] Preferably, grooves are formed on both sides of the channel of the moving groove, and conveyor belts are connected in both grooves. The two conveyor belts are in contact with the bottom of the moving seat. A plurality of card slots are formed on the surface of the moving seat, and a limiting plate is fixedly arranged on one side of the surface of the moving seat close to the positioning seat.

[0012] By adopting the above technical solution, the grooves of the moving groove reserve space for the installation of the conveyor belt. At the same time, the conveyor belt drives the moving seat to move horizontally along the moving groove, thus completing the transportation of the material. At the same time, the limiting plate is fixed on the surface of the moving seat, which is convenient for the subsequent clamping and fixing of the positioning device.

[0013] Preferably, a connecting block is threadedly connected to the surface of the lead screw inside the moving mechanism. An electric push rod I is fixedly arranged on the top of the connecting block, and the telescopic end of the electric push rod I movably penetrates through the connecting block and is fixedly connected to the top of the feeding plate.

[0014] By adopting the above technical solution, the connecting block moves inside the moving mechanism to drive the feeding plate to move synchronously. At the same time, the telescopic end of the electric push rod I extends to drive the feeding plate to press downwards, thereby shortening the adsorption distance of the material and driving the material to move.

[0015] Preferably, electric push rods II are fixedly arranged at the positions of the left U-shaped end of the feeding plate corresponding to the plurality of card slots. The telescopic ends of the plurality of electric push rods II movably penetrate through the bottom of the feeding plate and are connected with a pressing ring. The bottom surface of the pressing ring is flush with the bottom surface of the negative pressure suction port.

[0016] By adopting the above technical solution, the negative pressure suction port adsorbs the material. When the feeding plate moves the material to the top of the moving seat, the telescopic end of the electric push rod II extends to drive the pressing ring to press downwards, applying a downward thrust to the top of the material, so that the material falls onto the surface of the moving seat, thus completing the picking and placing of the material.

[0017] Preferably, through slots are provided at the positions of the feeding plate corresponding to the multiple negative pressure suction ports, and the inner walls of the multiple through slots are fixedly inserted with the negative pressure suction ports.

[0018] By adopting the above technical solution, the negative pressure suction port is movably inserted into the through slot and fixed with a nut, thereby reserving space for the fixation of the negative pressure suction port.

[0019] Preferably, a positioning plate is fixedly provided at the top of the positioning seat at the position of the pressing ring, and the width of the inner surface of the positioning plate is the same as the width of the outer surface of the pressing ring.

[0020] By adopting the above technical solution, the pressing ring presses down to form the outer surface of the pressing ring in contact with the inner wall of the positioning plate, thereby completing the docking of the material and playing an auxiliary positioning effect at the same time.

[0021] Preferably, a plurality of support plates are fixedly provided on one side of the top of the main base close to the positioning seat, and a rotating rod is rotatably arranged through the middle of each of the plurality of support plates, and a limiting block is fixedly provided on the surface of the rotating rod at the position of the limiting plate.

[0022] By adopting the above technical solution, the rotation of the rotating rod drives the limiting block to abut against the groove in the middle of the limiting plate (9), thereby positioning the moving seat and playing a limiting and clamping role at the same time.

[0023] Preferably, a rotating seat is fixedly connected to the bottom of each of the plurality of storage boxes, transparent plates are connected to the opposite sides of the plurality of storage boxes, and the transparent plates are connected to the storage boxes through opening and closing members fixed by screws. Material plates are placed inside the storage boxes, inside the positioning plates, and inside the card slots.

[0024] By adopting the above technical solution, the rotating seat drives the plurality of storage boxes to rotate so as to align with the positioning seat (4) for convenient replenishment of materials, and the materials in the storage boxes are transported to the inside of the positioning plates and the card slots through the feeding mechanism for the feeding process.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The right end of the feeding plate drives the material plate into the positioning plate for clamping and positioning, and then the left end of the feeding plate adsorbs the material plate and moves it into the card slot. While the negative pressure suction port adsorbs, the electric push rod drives the pressing ring to press down, generating a thrust on the material plate so as to be clamped in the card slot, thereby completing the positioning operation of the material plate. As the conveyor belt drives the moving seat to move horizontally, the material plate is transported into the wire harness production line for assembly, forming an automated production, reducing costs and improving production efficiency at the same time.

[0035] The following will further elaborate on this application in conjunction with the attached Figures 1 - 5 for a more detailed description of this application

[0036] The embodiment of this application discloses a feeding device for flexible wire harnesses

[0037] Refer to Figure 1 , Figure 2 , a feeding device for flexible wire harnesses, including a main base 1. The main base 1 is integrally T-shaped, and a moving groove 2 is opened inward on the upper end surface of the T-shape. Grooves are opened inward on both sides of the groove of the moving groove 2. A conveyor belt 7 is installed in the two grooves, and a moving seat 3 is abutted against the opposite side of the two conveyor belts 7 in the moving groove 2. The moving seat 3 is integrally T-shaped, and a card slot 8 is opened inward on the upper surface of the moving seat 3. Both ends of the card slot 8 penetrate through the moving seat 3 to communicate with the outside for easy picking. At the same time, a plurality of support plates 10 are fixed on the side wall of the T-shaped protrusion of the main base 1, and a rotating rod 11 passes through the middle of the plurality of support plates 10 movably. The end of the rotating rod 11 is connected to a motor device outside to keep rotating, and a limiting block 12 is fixed on the surface of the rotating rod 11 at the position of the limiting plate 9.

[0038] It should be noted that the outside of the conveyor belt 7 is connected to a motor device to keep running, and a plurality of moving seats 3 are transported inside the conveyor belt 7 in sequence to enter the device for feeding operation.

[0039] The conveyor belt 7 is fixed on both sides of the inner wall of the moving groove 2, so that the crawler of the conveyor belt 7 applies a clamping force to both sides of the bottom of the moving seat 3, thereby driving the movement of the moving seat 3, thereby driving the material to be translated. As the moving seat 3 moves, the moving groove 2 limits the moving seat 3 to make the moving seat 3 in a linear translation state, which plays an auxiliary positioning role for the subsequent feeding mechanism 5. At the same time, the rotating rod 11 drives the limiting block 12 to rotate, so that the limiting block 12 is clamped with the groove of the limiting plate 9, forming the positioning and fixing of the moving seat 3.

[0040] Refer to Figure 1 , Figure 3 , Figure 5 , a positioning seat 4 is fixed by screws on the upper surface of the main base 1 on one side of the limiting block 12. Positioning plates 13 are fixedly arranged at the positions of the clamping grooves 8 on the upper surface of the positioning seat 4, and grooves are formed around the top of the positioning seat 4 between the positioning plates 13, and the length of the inner wall of the groove is the same as the length of the clamping groove 8. At the same time, a rotating seat 16 is fixedly arranged on the outer surface of the main base 1 on one side of the positioning seat 4. The bottom of the rotating seat 16 is docked with the motor device, and a turntable is arranged on the top of the rotating seat 16. Four storage boxes 6 are connected around the surface of the turntable. A transparent plate 15 is movably abutted against one side surface of each storage box 6 away from each other. The transparent plate 15 is made of glass material. The connection between the transparent plate 15 and the storage box 6 forms a cavity inside the storage box 6, and a plurality of material plates 17 are placed in the cavity.

[0041] It should be noted that opening and closing members 14 are fixed by screws on both sides where the plurality of transparent plates 15 are connected to the storage box 6. The opening and closing members 14 can be disassembled by screws, so that the transparent plates 15 can be movably opened and closed on the storage box 6, facilitating the placement of the material plates 17 into the cavity of the storage box 6.

[0042] The rotation of the turntable of the rotating seat 16 drives the rotation of the plurality of storage boxes 6, so that the storage box 6 containing the material plates 17 is aligned with the positioning seat 4, facilitating the subsequent material transportation process of the feeding mechanism 5, and replacing the storage box 6 that has used up the material plates 17. Personnel can observe the quantity of the material plates 17 inside the storage box 6 through the transparent plate 15 for easy replacement. At the same time, the positioning plate 13 receives the material plates 17 and forms a clamping connection, thereby positioning the material plates 17, facilitating the grasping action of the feeding mechanism 5.

[0043] Refer to Figure 1 , Figure 4, the feeding mechanism 5 includes a moving mechanism 51 disposed on one side of the moving base 3 at the top of the main base 1. The housing of the moving mechanism 51 is fixedly connected to the external cavity, and a motor device is connected to the end of the housing of the moving mechanism 51. A threaded lead screw is disposed inside the moving mechanism 51, and a connecting block 52 is threadedly connected to the surface of the threaded lead screw. One end of the connecting block 52 away from the lead screw protrudes outside the housing of the moving mechanism 51, and an electric push rod 53 is fixedly provided on the upper end surface of the connecting block 52 located outside. The telescopic end of the electric push rod 53 movably penetrates through the bottom of the connecting block 52 and is fixedly connected to a feeding plate 54. The feeding plate 54 is integrally U-shaped, and a plurality of groups of through slots 57 are formed in a four-by-four group on the U-shaped surface. A negative pressure suction port 58 is inserted into each through slot 57, and the negative pressure suction port 58 is fixed to the through slot 57 by a nut.

[0044] It should be noted that the top of the negative pressure suction port 58 is connected to an external negative pressure sending device through a pipeline, so as to transmit negative pressure suction to adsorb the material plate 17. At the same time, electric push rods 55 are fixedly provided on the U-shaped left end surface of the feeding plate 54 at the central positions of a plurality of groups of clamping slots 8. The telescopic ends of the electric push rods 55 movably penetrate through the bottom of the feeding plate 54. The telescopic end of the feeding plate 54 is fixedly connected to a pressing ring 56, and the bottom of the pressing ring 56 is flush with the suction port at the bottom of the negative pressure suction port 58.

[0045] The rotation of the lead screw of the moving mechanism 51 drives the connecting block 52 to translate. As the connecting block 52 translates, it drives the electric push rod 53 to move synchronously. The electric push rod 53 operates to extend its telescopic end, thereby pushing the feeding plate 54 downward to shorten the distance between the negative pressure suction port 58 and the material plate 17. As the negative pressure suction port 58 is connected to the negative pressure to generate suction, the material plate 17 is adsorbed at the suction port of the negative pressure suction port 58 to form a grasping action and follows the movement of the feeding plate 54 to change positions. Then, the telescopic ends of the electric push rods 55 extend to push the pressing ring 56 downward, so that the material plate 17 falls into the clamping slot 8, thereby completing the grasping and placing process of the material plate 17.

[0046] Among them, the moving mechanism 51, the electric push rod 53, the electric push rod 55, the conveyor belt 7, the negative pressure suction port 58, and the externally connected negative pressure sending device and motor device of this device are all prior arts, and their structures will not be described in detail.

[0047] The implementation principle of the feeding device for a flexible wire harness in an embodiment of this application is as follows: When using this device, the material plate 17 needs to be filled in the storage box 6. Then, the rotation of the lead screw in the moving mechanism 51 drives the connecting block to move horizontally, thereby driving the feeding plate 54 to move. When the U-shaped right end of the feeding plate 54 is aligned with the top of the storage box 6, the telescopic end of the electric push rod 53 extends, thereby driving the feeding plate 54 to move downward;

[0048] When the bottom of the negative pressure suction port 58 is about to contact the material plate 17 in the storage box 6, the negative pressure sending device is started to generate negative pressure and convey it through a pipeline to the negative pressure suction port 58, thereby generating suction to adsorb the material plate 17 at the bottom of the negative pressure suction port 58. Then, the electric push rod 53 drives the feeding plate 54 to rise, and the moving mechanism 51 drives the right end of the feeding plate 54 to move to the alignment state with the positioning plate 13. As the electric push rod 53 extends downward, the feeding plate 54 drives the material plate 17 to be clamped on the inner wall of the positioning plate. 13, and the negative pressure suction port 58 at the right end of the feeding plate 54 stops adsorbing, so that the material plate 17 is placed in the positioning plate 13.

[0049] Then, the moving mechanism 51 and the electric push rod 53 repeat this process. When the right end of the feeding plate 54 adsorbs the material plate 17 again, the negative pressure suction port 58 at the left end of the feeding plate 54 adsorbs the material plate 17 in the positioning plate 13. And when the right end of the feeding plate 54 moves above the positioning plate 13 again, the left end of the feeding plate 54 drives the positioned material plate 17 to move above the card slot 8. At this time, the electric push rod 55 extends, thereby pushing down the pressing ring 56 downward to press the material plate 17 into the card slot 8. Then, the conveyor belt 7 drives the whole moving seat 3 to move into the subsequent wire harness docking mechanism, and transports the next moving seat 3 to the position directly below the feeding plate 54. Repeat this process to complete the positioning and transportation operations of the material plate 17, and achieve automated production, reducing costs while improving production efficiency.

[0050] The above are only optional embodiments of the present disclosure and are not used to limit the present disclosure. For those skilled in the art, the present disclosure can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present disclosure shall be included within the protection scope of the present disclosure.
