Description

Technical Field

[0001] This application relates to the field of terminal technology, and in particular to a terminal crimping device. Background Technology

[0002] A terminal crimping machine is a mechanical device used for processing wires and cables. It is mainly used to crimp metal terminals (also called terminal heads) to the ends of wires to facilitate connection and disconnection. Terminal crimping machines are widely used in many industries, such as electronics and electrical appliances, for connecting electrical components such as circuit boards, wires and cables.

[0003] In existing technologies, a stable electrical connection is generally formed by crimping metal terminals to the end of the wire. Conventional crimping machines require manual placement of the wire into the terminal head before crimping.

[0004] Manual operation can easily lead to incomplete crimping of the wire and terminal head, insufficient wire placement resulting in unstable crimping of the terminal head, or wire placement at an angle causing incomplete wire wrapping of the terminal head. Furthermore, crimped terminal wires produced based on manual experience may not meet the standard and are prone to defects. Utility Model Content

[0005] The purpose of this application is to provide a terminal crimping device to improve the problem that the crimped terminal wires produced by placing wires based on manual experience are inconsistent in standard and prone to defects.

[0006] This application provides a terminal crimping device, which adopts the following technical solution:

[0007] A terminal crimping device includes a workbench, a conveying assembly, a crimping mechanism, a pushing mechanism, and a wire securing mechanism. The wire securing mechanism is mounted on the crimping mechanism and includes a clamping motor, a rotating motor, and a turntable. The turntable is located at the output end of the rotating motor, and a clamping groove is formed on the side of the turntable. The clamping groove is a hemispherical groove. The side of the rotating motor is connected to the output end of the clamping motor, and the clamping motors are arranged in corresponding groups.

[0008] By adopting the above technical solution, the wire is clamped and rotated by a wire-fixing mechanism, ensuring that the wire extends accurately to the crimping area of ​​the crimping terminal and preventing the power wire from being crooked. The extension length of the wire is controlled by the number of rotations of the turntable controlled by the rotating motor, which prevents the wire from being crimped too short, thus avoiding poor contact. This standardizes the crimping of terminals and reduces the defect rate.

[0009] Optionally, an adhesive strip is provided in the clamping groove, and the adhesive strip is wound several times in the clamping groove.

[0010] By adopting the above technical solution, the friction is increased by setting the rubber strip, which prevents the wire from moving in the clamping groove. The rubber strip wrapping installation method facilitates installation and replacement.

[0011] Optionally, the pressing mechanism includes a drive motor, an auxiliary component, a pressing head, and a pressing plate. The pressing plate is mounted on a workbench, the auxiliary component is mounted on the pressing plate, and the auxiliary component has a mating groove. The drive motor is mounted above the auxiliary component, and the pressing head is mounted at the output end of the drive motor. The output end of the drive motor is slidably connected to the mating groove.

[0012] By adopting the above technical solution, the terminals are crimped onto the wires by setting a crimping mechanism, and the crimping of the drive motor output end is made more stable by setting auxiliary components, reducing shaking and increasing crimping quality.

[0013] Optionally, the crimping connector is provided with a crimping groove, which is an "M"-shaped opening groove, and the crimping plate is provided with a crimping groove corresponding to the crimping connector.

[0014] By adopting the above technical solution and setting an "M"-shaped opening crimping groove, the terminal can be wrapped and installed on the wire under pressure, and the crimping groove is set to cooperate with the crimping groove for crimping.

[0015] Optionally, the pushing mechanism includes a pushing motor, a clamping seat, and a push rod. The clamping seat is disposed at the output end of the pushing motor, one end of the push rod is fixed on the clamping seat, and an adjustment component is disposed on the worktable. The pushing motor is disposed on the adjustment component.

[0016] By adopting the above technical solution, a pushing mechanism is set to push the terminal to the crimping area for crimping, and a clamping seat is set to facilitate the replacement of the push rod and adapt to different terminals.

[0017] Optionally, the end of the push rod away from the push motor is provided with a fixing groove that can communicate with the pressure groove, and a magnet is provided on the bottom surface of the fixing groove.

[0018] By adopting the above technical solution, by setting a fixed groove to store the terminal, the terminal will not deviate in direction under the action of the push rod. By setting a magnet to hold the terminal, it is ensured that the terminal will not shake during the crimping process and affect the crimping quality.

[0019] Optionally, the adjustment assembly includes a movable plate, an adjusting bolt, and a fixing nut; the threaded end of the adjusting bolt passes through the movable plate and is threadedly connected to the worktable, the fixing nut is threadedly connected to the adjusting bolt, and the fixing nut cooperates with the adjusting bolt to fix and clamp the movable plate.

[0020] By adopting the above technical solution, the height of the drive motor can be adjusted by setting an adjustment component to accommodate push rods of different sizes and to make the sliding connection between the push rod and the pressure plate tighter, thus avoiding terminal jamming.

[0021] Optionally, the conveying assembly includes a platform and a conveying pipe, one end of which is connected to a terminal head production device, the platform is set on a workbench, and the conveying pipe is placed on the platform.

[0022] By adopting the above technical solution, the crimping efficiency is improved by setting up a conveying pipe and a conveying platform to stabilize and fix the conveying platform.

[0023] In summary, this application includes at least one of the following beneficial technical effects of the terminal crimping device:

[0024] 1. By setting up a wire clamping mechanism to rotate and hold the wire, the wire is accurately extended to the crimping area of ​​the crimping terminal, avoiding the power wire from being crimped. The extension length of the wire is controlled by the number of rotations of the turntable controlled by the rotating motor, so as to avoid poor contact caused by the wire being crimped too short. The terminal crimping standard is standardized and the defect rate is reduced.

[0025] 2. By setting an "M"-shaped opening crimping groove, the terminal can be wrapped and installed on the wire under pressure, and crimping is performed by setting a crimping groove in conjunction with the crimping groove;

[0026] 3. By setting a fixed groove to store the terminal, the terminal will not shift its direction under the action of the push rod. By setting a magnet to hold the terminal, it is ensured that the terminal will not shake during the crimping process and affect the crimping quality. Attached Figure Description
