A large-scale electronic component attachment plug and its insertion method

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 a plug for attaching an electronic component and a method for attaching and inserting it, in particular to a plug for attaching a large electronic component and a method for attaching and inserting it. Background technique [0002] The placement and insertion machine is configured after the dispensing machine or screen printing machine in the production line. It is a device that accurately attaches and inserts electronic components to the PCB pads by moving the plug. The automatic placement and insertion machine is a device used to realize high-speed, high-precision automatic placement and insertion of electronic components. It is the most critical and complex equipment in the entire SMT production. The placement and insertion machine has developed from the early low-speed mechanical placement and insertion machine. It is a high-speed optical centering and inserting machine, and it is developing towards multi-functional and fle...
