Description

Technical Field

[0001] The present application relates to the technical field of wiring harness production equipment, and in particular to a quick material replacement device for automobile wiring harness terminals. Background Art

[0002] Wire harness terminals are also called wiring terminals. Wire harness terminals are connected to both ends of the wire harness and are used to connect to power sources or other electrical components.

[0003] Terminals are usually stored in the form of terminal strips, which are coiled on a core barrel to form a terminal plate. During the terminal crimping process, the terminal plate is hung on the frame of the terminal crimping machine. When a force is applied to one end of the terminal strip, the terminal plate can rotate to unwind and complete the terminal pair loading.

[0004] However, in the actual production process, there are many types of terminals, and the terminal crimping machine usually needs to crimp multiple terminals. When another type of terminal needs to be crimped, the terminal plate needs to be replaced, which is time-consuming and affects the production efficiency of the wiring harness, and thus has a certain impact on the production efficiency of the entire electronic product. Utility Model Content

[0008] By adopting the above technical solution, during the terminal crimping process, the axis of the terminal plate is parallel to the sliding direction of the sliding frame, and then multiple terminal plates are arranged on the sliding frame along the sliding direction of the sliding frame. As the sliding frame slides, multiple terminal plates can be driven to alternately correspond to the terminal crimping machine set on one side of the sliding frame, so as to quickly realize the replacement of terminal plates, improve the production efficiency of wire harnesses, and reduce the impact on the overall production of electronic products.

[0020] By adopting the above technical solution, the terminal strip extends downward, bypasses the guide member and extends toward the terminal crimping machine, thereby controlling the angle at which the terminal strip enters the terminal crimping machine, making it convenient for workers to crimp the terminals.

[0021] Optionally, a limiting member is arranged on a side of the guide member away from the terminal crimping machine, and a limiting hole for the terminal strip to pass through is formed between the limiting member and the guide member.

[0022] By adopting the above technical solution, the terminal strip is inserted into the limiting hole, and the limiting hole limits the terminal strip, preventing the terminal strip from moving in a direction away from the guide member, causing the terminal strip to separate from the guide member, thereby improving the stability of the terminal strip's movement during the loading process.

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-3 This application is described in further detail.

[0029] Reference Figure 1 and Figure 2, is a fast material changing device for automobile wiring harness terminals disclosed in the present application, comprising a support table 1 and a sliding frame 2, wherein the sliding frame 2 is connected to the support table 1 by sliding in a horizontal direction.

During the terminal crimping process, a plurality of terminal discs 8 are arranged on the sliding frame 2 along the sliding direction of the sliding frame 2. By sliding the sliding frame 2, a plurality of terminal discs 8 can be alternately corresponded to the terminal crimping machine 3, thereby realizing fast material changing of the terminals.

[0030] Reference Figure 1 and Figure 3 , a sliding assembly 4 is arranged between the sliding frame 2 and the support platform 1, and the sliding assembly 4 includes a fixed rod 41 and a sliding block 42, and the fixed rod 41 is arranged horizontally and fixedly connected to the support platform 1 by screws. A sliding hole is opened on the sliding block 42, and the sliding block 42 is slidably sleeved on the fixed rod 41. The sliding frame 2 is fixedly connected to the sliding block 42 to realize the sliding connection between the sliding frame 2 and the support platform 1. In order to improve the sliding stability of the sliding frame 2, the sliding assembly 4 can be arranged in multiple groups at intervals in a direction perpendicular to the sliding direction of the sliding frame 2, and two groups are arranged in this embodiment.

[0031] Reference Figure 1 and Figure 3 The sliding frame 2 includes a plurality of support rods 21 arranged in parallel and spaced apart along the sliding direction of the sliding block 42 and at least one connecting rod 22 arranged in a direction perpendicular to the support rods 21. In this embodiment, the number of support rods 21 is 4 and the number of connecting rods 22 is 1. The connecting rod 22 is welded and connected with the plurality of support rods 21 to form the sliding frame 2. The terminal disk 8 is arranged between two adjacent support rods 21, and the terminal disk 8 can rotate around its own axis. The two end faces of the terminal disk 8 can abut against the opposite side faces of the two adjacent support rods 21, so that the movement of the terminal disk 8 in the direction parallel to its own axis can be limited, thereby improving the stability of the terminal disk 8 during the unwinding process.

[0032] Reference Figure 1 and Figure 3 A limiting groove 23 is provided on the side of the support rod 21 facing away from the ground, and the limiting groove 23 penetrates the support rod 21 along the sliding direction of the sliding frame 2. A rotating shaft 25 is provided in the limiting groove 23, and the rotating shaft 25 is inserted into a plurality of limiting grooves 23 at a time. The rotating shaft 25 is a cylindrical structure and can rotate around its own axis in the limiting groove 23. The terminal plate 8 is sleeved on the rotating shaft 25 to realize the rotation connection between the terminal plate 8 and the sliding frame 2. The rotating shaft 25 can be moved out of the limiting groove 23 away from the ground by moving the rotating shaft 25 along the length direction of the support rod 21, so as to facilitate the replacement of the terminal plate 8.

[0033] Reference Figure 1and Figure 3 The sliding frame 2 further includes a support plate 24, which is horizontally arranged between the support rods 21 and the sliding block 42. A plurality of support rods 21 are welded to the support plate 24 at one end close to the ground. The sliding block 42 is fixedly connected to the support plate 24 by screws. The support plate 24 provides an installation space for the sliding block 42, which facilitates the installation of the sliding block 42, thereby improving the stability of the sliding frame 2 supporting the terminal plate 8.

The sliding support plate 24 enables the positioning member 5 to correspond to different slots 11, so that the sliding frame 2 can be positioned at different positions, thereby improving the stability of the terminal plate 8 during the unwinding process.

[0035] Reference Figure 1 and Figure 2 The slide frame 2 is provided with a guide 6, which is arranged below the terminal plate 8. After the terminal plate 8 is unwound, the terminal strip extends downward to below the guide 6, and then extends toward the direction close to the terminal crimping machine 3. The guide 6 changes the extension direction of the terminal strip, thereby changing the angle of the terminal strip when entering the terminal crimping machine 3, reducing the interference between the terminal strip and the terminal crimping machine 3, and facilitating the crimping of the terminal by the staff.

[0036] Reference Figure 1 and Figure 2 The guide member 6 is an arc-shaped plate structure. The guide member 6 is arranged on the side of the sliding frame 2 away from the terminal crimping machine 3, and the opening is facing the terminal crimping machine 3. The terminal strip is in contact with the outer wall of the guide member 6 to improve the stability of the terminal strip during the sliding process relative to the guide member 6.

[0037] Reference Figure 1 and Figure 3 The guide member 6 is provided with a limit member 7, which includes a horizontal bar 71 and a vertical bar 72. Two vertical bars 72 are provided, and the two vertical bars 72 are respectively welded vertically at both ends of the horizontal bar 71 to form a U-shaped structure.

The limit member 7 blocks the terminal strip from moving in the direction away from the guide member 6, thereby reducing the occurrence of the terminal strip being separated from the guide member 6 after the terminal crimping machine 3 is stopped.

[0038] The implementation principle of this embodiment is: by sliding the sliding frame 2, different pairs of terminal discs 8 are quickly matched with the terminal crimping machine 3, thereby increasing the speed of replacing the terminal discs 8 and reducing the impact of the replacement of the terminal discs 8 on the production of the wiring harness.
