Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness terminal crimping technology, specifically an automotive wiring harness terminal crimping device. Background Technology

[0002] Automotive wiring harness terminals are connectors or joints used to connect wire harnesses of different components in an automotive electrical system. The terminals act as connection points for the wire harnesses, allowing different wires to be connected together. Crimping of automotive wiring harness terminals is a tool or machine used to connect the wires in the wiring harness to the terminals. By applying appropriate pressure and heat, the metal parts between the wires and terminals are connected together to ensure smooth current transmission and a stable connection.

[0003] When crimping wire harness terminals, the cables are usually fed into the crimping device manually and inserted into the terminal by hand. The machine then crimps the cable, and the cable is manually removed after crimping. This process is repeated, which not only allows for the crimping of only one cable at a time, but also requires workers to manually insert the cable into the terminal each time. This is time-consuming and labor-intensive. In the early stages, when workers are not proficient, the crimping efficiency is very low. Even after workers become familiar with the operation, such frequent manual insertion is still very tiring.

[0004] Therefore, we propose an automotive wiring harness terminal crimping device to solve the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an automotive wiring harness terminal crimping device. This solves the problem mentioned in the background art, where crimping wiring harness terminals often involves manually feeding the cable into the crimping device, manually inserting the cable into the terminal, then controlling the machine to crimp, and then manually removing it. This cycle repeats, allowing only one cable to be crimped at a time, and requiring manual insertion each time. This is time-consuming and labor-intensive. Initially, when workers are not proficient, crimping efficiency is very low. Even after workers become familiar with the operation, such frequent manual insertion is very tiring, increasing labor intensity and posing certain safety hazards. Furthermore, each manual insertion and removal creates gaps in the machine, further reducing work efficiency.

[0009] An automotive wiring harness terminal crimping device includes a body, a support base fixed at one end of the top of the body, a stamping table distributed at the front end of the support base, and a fixed base distributed at the end of the stamping table away from the support base.

[0010] A drive motor is fixedly mounted on the front surface of the fixed base, and a transmission roller is connected to the output end of the drive motor. A conveyor belt is fitted on the outer ring surface of the drive motor, and a fixed frame is distributed above the conveyor belt. A damper is fixedly mounted at the top center of the fixed frame, and a lower pressure seat is fixedly connected to the bottom of the damper. A guide rod is fixedly mounted on one side of the top of the lower pressure seat, and a spring is fitted on the outer ring surface of one end of the guide rod. A pressure roller is connected to the bottom inner side of the lower pressure seat. A support is distributed at the front end of the conveyor belt, and a first cylinder is fixedly mounted at the top front end of the support.

[0011] Furthermore, a second cylinder is fixedly mounted on the top of the support base, and the output end of the second cylinder is connected to a punch head, and an auxiliary roller is rotatably connected to one side of the top of the punch table.

[0012] Furthermore, the guide rods are symmetrically distributed along the vertical center line of the lower pressure seat, and the guide rods are perpendicular to the lower pressure seat.

[0013] Furthermore, the two ends of the spring are respectively fixedly connected to one side of the top of the lower pressure seat and one side of the bottom of the fixing frame.

[0014] Furthermore, the pressure roller is rotatably connected to the lower pressure seat via a bearing seat, and the pressure rollers are equidistantly distributed along the bottom of the lower pressure seat.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides an automotive wiring harness terminal crimping device, which has the following advantages:

[0018] This utility model, through its structure including a drive motor, conveyor belt, pressure roller, and pusher block, facilitates the lateral transport of cables to be crimped.

Detailed Implementation

[0024] 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.

[0025] Example

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the present invention provides an automotive wiring harness terminal crimping device, including a body 1, a support base 2 fixed at one end of the top of the body 1, a stamping table 3 distributed at the front end of the support base 2, and a fixed seat 4 distributed at the end of the stamping table 3 away from the support base 2.

[0027] A drive motor 5 is fixedly mounted on the front surface of the fixed base 4, and a transmission roller 6 is connected to the output end of the drive motor 5. The end of the transmission roller 6 away from the drive motor 5 is rotatably connected to the fixed base 4 through a bearing seat. The transmission roller 6 is symmetrically distributed along the vertical center line of the conveyor belt 7. The outer ring surface of the drive motor 5 is fitted with the conveyor belt 7, and a fixed frame 8 is distributed above the conveyor belt 7. Holes for sliding guide rods 11 are opened on both sides of the top of the fixed frame 8. A damper 9 is fixedly mounted in the middle of the top of the fixed frame 8. The bottom of the conveyor belt 7 is fixedly connected to a lower pressure seat 10. A guide rod 11 is fixedly provided on one side of the top of the lower pressure seat 10, and a spring 12 is sleeved on the outer ring of one end of the guide rod 11. A pressure roller 13 is connected to the inner side of the bottom of the lower pressure seat 10. Supports 14 are distributed at the front end of the conveyor belt 7, and a first cylinder 15 is fixedly provided at the front end of the top of the support 14. A push block 16 is connected to the output end of the first cylinder 15. The bottom of the push block 16 is attached to the upper surface of the conveyor belt 7, and the push block 16 can be rotatably connected to the output end of the first cylinder 15.

[0028] In use, the arranged terminals are laterally conveyed along the stamping table 3 under the action of the external structure. When a single terminal is conveyed to the protruding position in the middle of the stamping table 3, the cable to be crimped is placed in an arranged manner on the upper surface of the conveyor belt 7. Then, the drive motor 5 works to make the transmission roller 6 connected to its output end rotate. At this time, the rotation of the transmission roller 6 drives the conveyor belt 7 on its outer surface to move, thereby using the movement of the conveyor belt 7 to laterally convey the arranged cables. When the cable is conveyed to one end of the push block 16, the first cylinder 15 works to push the push block 16 connected to its output end, thereby making the push block 16 move along the upper surface of the conveyor belt 7, so that the push block 16 can be used to push the cable. One end of the cable is pushed onto the pressing table 3 to make contact with the terminal, which facilitates subsequent crimping. When the cable is transported laterally, the pressure roller 13 is pushed longitudinally. At this time, the pressure roller 13 is pushed longitudinally, which drives the lower pressure seat 10 to move longitudinally. Then, the lower pressure seat 10 drives the guide rod 11 to move longitudinally along the fixed frame 8. As the lower pressure seat 10 moves, the spring 12 also deforms and generates a reverse force. The damper 9 also deforms. The reverse force generated by the deformation of the damper 9 and the spring 12 can push the lower pressure seat 10 in the opposite direction, so that the lower pressure seat 10 drives the pressure roller 13 to reset, which facilitates the use of the pressure roller 13 to assist in the lateral transport of the cable.

[0029] like Figure 4 As shown, in some embodiments, a second cylinder 17 is fixedly provided at the top of the support base 2, and the output end of the second cylinder 17 is connected to a punch head 18, and an auxiliary roller 19 is rotatably connected to one side of the top of the punch table 3.

[0030] When in use, when one end of the cable is pushed above the stamping table 3 and comes into contact with the terminal, the second cylinder 17 works longitudinally to push the bottom of the fixedly connected stamping head 18, which facilitates the subsequent crimping of the cable and the terminal by the movement of the stamping head 18. The two auxiliary rollers 19 can assist in the lateral conveying of the terminals.

[0031] like Figure 2 and Figure 3 As shown, in some embodiments, the guide rods 11 are symmetrically distributed along the vertical center line of the lower pressure seat 10, and the guide rods 11 and the lower pressure seat 10 are distributed perpendicularly to each other.

[0032] During use, the longitudinal movement of the lower pressure seat 10 will drive the guide rod 11 to move longitudinally along the fixed frame 8, thereby using the movement of the guide rod 11 to improve the stability of the lower pressure seat 10 during longitudinal movement.

[0033] like Figure 2 and Figure 3 As shown, in some embodiments, the two ends of the spring 12 are respectively fixedly connected to one top side of the lower pressure seat 10 and one bottom side of the fixing frame 8.

[0034] When in use, when the guide rod 11 moves longitudinally under the action of the lower pressure seat 10, the lower pressure seat 10 will cause the spring 12 to deform. When the spring 12 deforms, it will generate a reverse force, which, together with the setting of the damper 9, can achieve the purpose of buffering.

[0035] like Figure 2 and Figure 3 As shown, in some embodiments, the pressure roller 13 is rotatably connected to the lower pressure seat 10 via a bearing seat, and the pressure roller 13 is equidistantly distributed along the bottom of the lower pressure seat 10.

[0036] In use, since the pressure roller 13 and the lower pressure seat 10 are rotatably connected, when the longitudinal movement of the lower pressure seat 10 causes the pressure roller 13 to contact the cable conveyed on the conveyor belt 7, the pressure roller 13 can not only press down and limit the cable, but also assist the cable in lateral conveying.

[0037] like Figure 4 As shown, in some embodiments, the auxiliary roller 19 is rotatably connected to one side of the top of the stamping table 3, and the auxiliary roller 19 is symmetrically distributed along the vertical center line of the stamping table 3.

[0038] In use, since the auxiliary roller 19 forms a rotatable connection with the stamping table 3, when the arranged terminals are transported laterally, the auxiliary roller 19 can be used to facilitate the lateral transport of the auxiliary terminals.

[0039] In summary, the arranged terminals are first transported laterally along the stamping table 3 under the action of the external structure. When a single terminal is transported to the protruding position in the middle of the stamping table 3, the cables to be crimped are placed in an arrangement on the upper surface of the conveyor belt 7. Then, the drive motor 5 and the working transmission roller 6 rotate to drive the conveyor belt 7 to move. The movement of the conveyor belt 7 is used to transport the arranged cables laterally. When the cable is transported to one end of the push block 16, the first cylinder 15 works to push the push block 16, causing the push block 16 to push one end of the cable onto the stamping table 3 and make contact with the terminal. Then, the second cylinder 17 works to push the stamping head 18. The movement of the punch head 18 is used to crimp the cable and the terminal. When the cable is transported laterally, it pushes the pressure roller 13 longitudinally. At this time, the pressure roller 13 is pushed longitudinally, which drives the lower pressure seat 10 to move longitudinally. Then, the lower pressure seat 10 drives the guide rod 11 to move longitudinally along the fixed frame 8. As the lower pressure seat 10 moves, the spring 12 also deforms and generates a reverse force. The damper 9 also deforms. The reverse force generated by the deformation of the damper 9 and the spring 12 can push the lower pressure seat 10 in the opposite direction, so that the lower pressure seat 10 drives the pressure roller 13 to reset. This makes it convenient to use the pressure roller 13 to assist in the lateral transport of the cable.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
