Description

Technical Field

[0001] This utility model belongs to the field of terminal processing, and in particular relates to a connector terminal processing device. Background Technology

[0002] Drilling is a necessary step in connector terminal production to form mounting holes and positioning holes. Stamping is a pressure processing method that uses a die mounted on a press to apply pressure to the material at room temperature, causing it to separate or plastically deform, thereby obtaining the desired part.

[0003] In the existing technology, when the terminal is placed on the mold for punching, the terminal strip is prone to misalignment with the mold during the stamping or conveying process, resulting in inaccurate punching position of the terminal, or even product scrap. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide a connector terminal processing device to prevent the material strip from falling off the guide groove during the conveying or stamping process, thereby ensuring the positional accuracy of the punching.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a connector terminal processing device, comprising a feeding mechanism, a punching mechanism, and a receiving mechanism, wherein the feeding mechanism is located upstream of the punching mechanism, and the punching mechanism is located upstream of the receiving mechanism;

[0006] The punching mechanism includes a carrier, a stamping plate, and a stamping module for driving the stamping plate downward. The carrier is mounted on a workbench, and its upper surface is recessed to form a guide groove that matches the strip material. The stamping plate is located above the carrier, and its lower surface is provided with stamping columns. The stamping plate has clamping structures at its upper and lower ends. The clamping structure includes a mounting base and several clamping wheels. The clamping wheels are rotatably connected to the mounting base. The mounting base has a slotted hole through which screws pass to connect with the carrier. The strip material is located between the clamping wheels and the guide groove. The clamping wheels prevent the strip material from detaching from the guide groove during conveying or stamping, thus ensuring the positional accuracy of the punching.

[0007] The carrier is provided with an air cavity, which is connected to a gas flow channel. The material strip includes terminals arranged along the length of the material strip. Each terminal is provided with an adsorption part. The air cavity is located below the adsorption part, and the adsorption part corresponds to the air cavity. The negative pressure of the air cavity is used to adsorb the terminals to prevent the material strip from falling off the guide groove.

[0008] Furthermore, the stamping module includes a fixed plate and a stamping cylinder. The stamping cylinder is fixed to the fixed plate, and the push rod of the stamping cylinder is connected to the stamping plate. The fixed plate is fixed to the upper end of the connecting rod, and the lower end of the connecting rod passes through the stamping plate and is connected to the carrier.

[0009] Furthermore, the gas flow channel is connected to the air pipe, and the air pipe is connected to the negative pressure pump.

[0010] Furthermore, the carrier is provided with a waste discharge hole corresponding to the stamping column, and a waste collection trough is provided below the waste discharge hole.

[0011] Furthermore, both the feeding mechanism and the receiving mechanism include a material tray and a rotary drive motor for driving the material tray to rotate. The material tray is connected to the output shaft of the rotary drive motor. The rotary drive motor is fixed to a guide block, the guide block is fixed to a bracket, and the bracket is fixed to a worktable.

[0012] Furthermore, it also includes a material guiding module, which includes a limiting rod, a tension spring, and a sliding block. The limiting rod has a limiting groove through which the material strip passes. The limiting rod is fixed to the sliding block, and the guide rod passes through the sliding block. The sliding block can slide along the length direction of the guide block. Both ends of the guide rod are respectively installed on the mounting block, which is fixed to the guide block. One end of the tension spring is connected to the mounting block, and the other end of the tension spring is connected to the sliding block.

[0013] Furthermore, the guide block is equipped with a limiting block to limit the movement of the sliding block.

[0015] The punching mechanism of this utility model includes a carrier, a stamping plate, and a stamping module that drives the stamping plate to press down. The upper surface of the carrier is recessed downward to form a guide groove that matches the strip material. The clamping structure includes a mounting base and several clamping wheels. The clamping wheels are rotatably connected to the mounting base. By setting the clamping wheels, the strip material is prevented from falling out of the guide groove during conveying or stamping, thus ensuring the positional accuracy of the punching. More preferably, the mounting base is provided with a waist-shaped hole, through which screws pass to connect with the carrier to accommodate strip material of different thicknesses.

[0016] The carrier of this utility model is provided with an air cavity, which is connected to a gas flow channel. The material strip includes terminals arranged along the length of the material strip. Each terminal is provided with an adsorption part.

One end of the tension spring is connected to the mounting block, and the other end of the tension spring is connected to the sliding block. After the material strip passes through the limiting groove, the amplitude of the material strip swing is reduced, which facilitates material collection and release. Attached Figure Description
