PCB pin header connector pin bending mechanism, pin bending method thereof and assembly production equipment

Abstract

The invention relates to the technical field of electronic component production and particularly relates to a pin bending mechanism, a pin bending method, a pin bending device and assembly production equipment for PCB pin header connectors. The mechanism comprises a driving assembly and a pin bending assembly, wherein the driving assembly comprises a pin bending air cylinder, a pin bending connecting rod, a rack, a rack sliding base and a gear; a lower end of the pin bending connecting rod is fixedly mounted on a piston rod of the pin bendingair cylinder, and an upper end of the pin bending connecting rod is connected with the rear end of the rack through a joint; the rack is installed in the rack sliding seat in a sliding mode, the rack sliding seat is fixedly installed on the machine frame, the gear is meshed with the rack, and the gear is installed on the pin bending assembly in a rotating mode; and the pin bending assembly comprises a bearing seat, a bearing, a mounting ring, a connecting plate and a pin bending plate. The mechanism is advantaged in that the air cylinder drives the rack and the gear to move, and a rotation angle of the gear can be accurately controlled by controlling the action of the air cylinder, so the pin bending angle of the pin bending plate is controlled, and consistency of pins after pin bending is conveniently improved.

Description

technical field [0001] The invention relates to the technical field of electronic component production, in particular to a pin bending mechanism, a bending method, a bending device and assembly production equipment of a PCB pin header connector. Background technique [0002] Pin header, a kind of connector, English name: Pin Header. This kind of connector is widely used in PCB circuit boards in electronics, electrical appliances, and instruments. Its function is to act as a bridge between blocked or isolated circuits in the circuit and take on the role of current or signal transmission. Task. It is usually used in conjunction with a female header to form a board-to-board connection; or it is used in conjunction with an electronic harness terminal to form a board-to-wire connection; it can also be used independently for a board-to-board connection. [0003] With the development of modern electronic equipment in the direction of miniaturization and density, the straight stru...

AI Technical Summary

Problems solved by technology

[0006] 1. The traditional bending mechanism cannot accurately control the angle of the bending foot, and the stitches often break, and the stitches after bending are poor in consistency, which affects the subsequent assembly

[0007] 2. Although the traditional pin header and connector bending equipment can realize automatic bending, it needs to manually load and move materials, the production and processing efficiency is low, and the scrap rate is high

[0008] 3. In the process of material transfer, the traditional pin connector requires a horizontally arranged cylinder and a vertically arranged cylinder to cooperate with each other to realize horizontal movement and vertical movement. The cost is high and it is not conducive to assembly production

[0009] 4. The connection between the material receiving action and the material shifting action of the traditional conveying device PCB pin connector is not tight, and the material shifting action can only be performed alone, and the newly loaded pin header connector cannot be transported to the material transfer mechanism, resulting in Low delivery efficiency

[0010] 5. When the traditional bending device bends the two rows of stitches, it usually bends the feet successively, but the later bending feet will affect the previous bending feet, thereby reducing the quality of the bending feet

[0011] 6. The feeding efficiency of the small connecting seat is low
