Description

Technical Field

[0001] The utility model relates to a wire harness production and processing device, in particular to a terminal riveting machine for wire harness assembly. Background Art

[0002] There are many types of cable harnesses. Some cable harnesses have metal wires exposed at the ends, and are subsequently connected directly through metal wires between cables. Another type of cable harness needs to have terminals connected to the ends, and the terminals are inserted into connectors. Subsequently, the cable harnesses are connected to the cable harnesses, or the cable harnesses and the equipment are connected using connectors.

[0003] When the terminal is connected to the end of the cable harness, the exposed metal wire at the end of the cable harness is placed on the terminal, and then the terminal and the metal wire are riveted together using a terminal riveting machine.

[0004] like Figure 1 As shown, the initial state of the terminal is a sheet structure, and multiple terminals are connected through a metal strip 101, and then the metal strip with the terminal 102 is sent into the riveting machine. It is only necessary to put the metal wire at the end of the cable harness where the terminal needs to be installed in the corresponding position, and the metal wire and the corresponding terminal can be riveted together through the terminal riveting machine. After the riveting is completed, the terminal is rolled into a corresponding shape (such as a cylindrical shape or other required shape that can clamp the metal wire) and detached from the metal strip. A metal strip traction mechanism will also be set at the rear end to pull the metal strip at a certain distance, so that each terminal will be moved to the terminal riveting position.

[0005] However, in the prior art, a feeding shaft is set at the top of the riveting press, and the metal strip with the terminal is mounted on the feeding shaft, while the terminal riveting position is located at the bottom of the riveting press. After the terminal strip is pulled out, it is transmitted through a side shaft or a transmission shaft. In this way, when the terminal with the metal strip enters the riveting press, the metal strip is easy to deviate, bend, or break. It is very inconvenient to manually adjust or manually put the broken metal strip back into the riveting press frequently. Summary of the invention

[0006] The utility model aims to provide a terminal riveting machine for wiring harness assembly. By using the structure, the stability of the terminal during transportation can be ensured, and the terminal can be prevented from bending and breaking.

At least one limiting member is arranged on the left side of the material guide plate, and a limiting material passing channel is formed between the limiting member and the material guide plate, and the left side of the material guide plate is inclined to the right from top to bottom.

[0009] In the above technical solution, the material guide plate includes a middle material guide plate, the top of the middle material guide plate is provided with an upper material guide plate bent toward the upper right, the bottom of the middle material guide plate is provided with a lower material guide plate bent toward the right, the connection between the upper material guide plate and the middle material guide plate is an arc structure, and the connection between the lower material guide plate and the middle material guide plate is an arc structure.

[0011] In the above technical solution, a sound-absorbing sponge is installed on the right side wall of the guide plate.

[0012] In the above technical solution, the bracket includes a cross bar and a longitudinal bar, the right end of the cross bar is connected to the left side of the top of the body, the rear end of the longitudinal bar is connected to the left end of the cross bar, and the right bottom surface of the guide plate is fixedly connected to the top of the longitudinal bar.

[0013] In the above technical solution, there are two limit members, and the two limit members are arranged at an interval up and down.

[0014] In the above technical solution, the limiting member is a U-shaped rod opening to the right, and a limiting material passing channel is formed between the U-shaped rod and the left side surface of the material guide plate.

[0019] 1. The present invention directly uses a material guide plate to guide the terminal strip, so that the terminal and the terminal strip can not only be guided by the material guide plate, but also supported by the material guide plate to prevent the terminal from rotating or bending relative to the terminal strip, and also to prevent the terminal strip from bending or breaking, effectively ensuring the stability and quality of the material guide and reducing the subsequent labor intensity of personnel;

[0026] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0027] Example 1: See Figure 2 , 3 As shown, a terminal riveting machine for wiring harness assembly includes a machine body 1, a material discharge shaft 2 is provided on the top of the machine body 1, a terminal feeding port 3 is provided on the left side of the bottom of the machine body 1, and a material guide is also provided on the left side of the machine body 1, and the material guide is installed on the left side of the machine body 1 through a bracket 4;

[0028] The material guide member includes a material guide plate 5, which is a C-shaped structure opened to the right. The top of the material guide plate 5 is connected to the bracket 4, and the bottom of the material guide plate 5 is arranged near the terminal feed port 3. At least one limiting member 6 is arranged on the left side of the material guide plate 5, and a limiting material passage 15 is formed between the limiting member 6 and the material guide plate 5, and the left side of the material guide plate 5 is inclined to the right from top to bottom.

[0029] In this embodiment, the terminal material strip disk is directly placed on the unwinding shaft, and after the end of the terminal material strip is pulled out, it passes through the left side wall of the guide plate, and then is pulled to the right and enters the terminal feed port into the body for riveting. In the process of the end of the terminal material strip moving to the right, the terminal material strip will be guided toward the lower left through the top of the guide plate during the process of being released from the unwinding shaft, and then guided through the left side wall of the guide plate, and finally guided through the bottom of the guide plate, so that after being released from the unwinding shaft, the position between the unwinding shaft and the terminal feed port will basically contact the guide plate, which can effectively prevent the terminal material strip from bending, especially bending or breaking between adjacent terminals of the terminal material strip, and ensure the stability and quality of the guide. The setting of the limiter allows the limiter to form a limit material passage between it and the guide plate, so that the terminal will be limited by the limiter to prevent it from moving back and forth on the guide plate and detaching from the guide plate, playing a limiting role and ensuring that the terminal material strip is transported within the corresponding track.

[0030] See also Figure 2 , 3 As shown, the material guide plate 5 includes a middle material guide plate 7, the top of the middle material guide plate 7 is provided with an upper material guide plate 8 bent toward the upper right, the bottom of the middle material guide plate 7 is provided with a lower material guide plate 9 bent toward the right, the connection between the upper material guide plate 8 and the middle material guide plate 7 is an arc structure 10, and the connection between the lower material guide plate 9 and the middle material guide plate 7 is an arc structure 10.

[0031] The right bottom surface of the upper material guide plate is connected to the bracket, the right end of the lower material guide plate is arranged at the upper left of the terminal feed opening, and the right end of the lower material guide plate is arranged close to the terminal feed opening.

[0032] In this embodiment, the upper guide plate is used to connect with the bracket. At the same time, the connection between the upper guide plate and the middle guide plate is an arc structure. After the terminal material strip is released, the material is reversed through the arc structure, so that the bending arc of the terminal material strip is smaller, and the arc structure is excessive, so as to prevent the terminal material strip from breaking due to the bending distance being too short, and also prevent the terminal material strip from being stuck at the connection between the upper guide plate and the middle guide plate, so as to ensure the smooth movement of the terminal material strip. Similarly, the lower guide plate guides the terminal material strip to enter the terminal feed port. The connection between the lower guide plate and the middle guide plate also adopts an arc structure, which can also prevent the terminal material strip from breaking due to the bending distance being too short, and also prevent the terminal from being stuck at the bending of the middle guide plate and the lower guide plate.

[0033] See also Figure 2 , 3 As shown, a sound-absorbing sponge 11 is installed on the right side wall of the guide plate 5. Since the terminal strip and the terminals on the terminal strip are made of metal materials, and in order to ensure the strength and service life of the guide, the guide piece is a metal plate with an integrated structure. Therefore, the terminal strip is always in contact with the guide plate, and when it moves, the contact between the terminal strip and the guide plate will cause the vibration of the guide plate and produce noise. By arranging an attracting sponge on the right side, the vibration can be reduced as much as possible, and while reducing the noise, the noise can also be absorbed to a certain extent, reducing the noise and improving the user experience.

[0034] Of course, a rubber layer or a cloth layer can also be set on the left side wall of the guide plate to reduce the rigid sliding contact between the two and further reduce noise. However, in this way, the friction between the terminal strip and the guide plate will be greater, and the terminal strip may scratch the rubber layer or the cloth layer, causing the scratched part to bulge, causing the terminal strip to get stuck and break during movement. Therefore, the cloth layer or the rubber layer needs to be replaced frequently, which is inconvenient. Using suction cotton is more effective.

[0035] See also Figure 2 , 3 As shown, the bracket 4 includes a cross bar 12 and a longitudinal bar 13, the right end of the cross bar 12 is connected to the left side of the top of the body 1, the rear end of the longitudinal bar 13 is connected to the left end of the cross bar 12, and the right bottom surface of the guide plate 5 is fixedly connected to the top of the longitudinal bar 13. Among them, the right side of the bottom of the upper guide plate is fixedly connected to the top of the longitudinal bar.

[0036] The crossbar and the longitudinal bar are arranged to install the material guide plate on the machine body, so that the material guide plate can be conveniently installed or removed from the machine body, and is also convenient for maintenance and replacement.

[0037] There are two limit members, which are spaced apart from each other.

[0038] The limiting member is a U-shaped rod that opens to the right, and a limiting material passage is formed between the U-shaped rod and the left side of the guide plate. The two U-shaped rods can limit the upper and lower sides of the terminal strip passing through the guide plate, preventing the terminal strip from shifting forward and backward on the guide plate, thereby ensuring the limiting quality. In addition, the U-shaped rod is used, and a hole is set on the middle guide plate, and a screw hole is set on the right end of the U-shaped rod. By directly passing the bolt through the hole and the screw hole of the U-shaped rod, the U-shaped rod and the guide plate can be quickly connected and fixed.

[0039] See also Figure 2 As shown, a vertical pole 14 is provided on the left side of the top of the body 1, and the unloading shaft 2 is installed on the top of the vertical pole 14, and the unloading shaft is arranged above the bracket. In this way, the unloading shaft can be raised, so that the diameter of the terminal material belt reel can be larger, and the terminal material belt reel with a larger diameter can be used for a longer time, and the terminals of more cable harness ends can be connected.

[0040] Wherein, the material guide is a metal plate with slight elasticity. In this way, the thickness of the material guide can be set thinner, the cost will be lower, and it can be bent to a certain extent, and the inclination angle of the middle material guide plate can be adjusted to make the conveying of the terminal material strip smoother and more stable, and also ensure the quality of the material guide. Moreover, because it has a certain elasticity, when the cable harness is riveted for terminal, when the riveting speed is faster, the traction speed will also be faster. When the traction speed is accelerated, the unwinding speed may not keep up. In this way, in the process of accelerating the traction of the terminal material strip, the bottom of the material guide can be bent to the right, thereby giving a certain reaction time for the unwinding, preventing the terminal material strip from being broken.
