Large-scale electronic element attaching-inserting joint and attaching-inserting method therefor

Abstract

The invention discloses a large-scale electronic element attaching-inserting joint and an attaching-inserting method therefor. The attaching-inserting joint comprises an attaching-inserting joint supporting base, a synchronous band apparatus I, a control motor I, an L-shaped sliding block, a clamping air cylinder, a synchronous band apparatus II, a control motor II, a chuck, a spline shaft, a spline shaft sleeve I, a spline shaft sleeve II, a pull rod and a thrust bearing; under the action of the clamping air cylinder, the chuck can be controlled to be in a clamped state or in a loosened state through the chuck so as to clamp or loosen the large-scale electronic element by the chuck; by controlling the rotation of the motor I, the synchronous band apparatus I can drive the L-shaped sliding block to move up and down in a perpendicular direction so as to drive the clamping air cylinder, the pull rod, the spline shaft, the spline shaft sleeve II and the chuck to move together; a driven wheel II of the synchronous band apparatus II is fixedly connected with the outer peripheral surface of the spline shaft sleeve I; by controlling the rotation of the control motor II, the driven wheel II can be driven to rotate so as to drive the spline shaft sleeve I, the spline shaft, the spline shaft sleeve II and the chuck to rotate in a horizontal direction around the axial line of the spline shaft to realize control for the rotating angle of the chuck.

Description

Technical field [0001] The invention relates to an electronic component sticking plug and a sticking method, in particular to a large electronic component sticking plug and a sticking method. Background technique [0002] The placement machine is configured after the glue dispenser or screen printer in the production line. It is a device that accurately pastes the electronic components onto the PCB pads by moving the paste plug. The automatic placement machine is a device used to achieve high-speed and high-precision automatic placement of electronic components. It is the most critical and complex equipment in the entire SMT production. The placement machine has been developed from the early low-speed mechanical placement machine It is a high-speed optical centering placement machine, and is developing towards multi-functional, flexible connection and modularization. As a crucial functional part of the placement machine, the sticking plug can quickly and accurately stick the ele...
