Electronic component placement equipment

Abstract

The invention discloses electronic component placement equipment. A placement mechanism comprises suction nozzles, a first motor which controls the suction nozzles to rotate, a second motor which controls the suction nozzles to move up and down, an air pipe which controls materials to be fed in or discharged out of the suction nozzles, wherein the second motor is arranged at the upper portion of the placement mechanism, the first motor is arranged on a connecting piece at the front portion of the placement mechanism, the connecting piece is perpendicular to the suction nozzles, the first motor controls the suction nozzles to rotate through a rotation synchronous belt and a rotation synchronous pulley, and the second motor controls the suction nozzles to move up and down through an up-down motion synchronous belt and an up-down motion synchronous pulley. The structure of the placement equipment has two freedom degrees, and components are sucked and placement operation is executed when the suction nozzles on a placement head of the placement equipment move up and down and rotate. The rotating angle of a spiral mechanical arm of the placement equipment is controlled by a computer, the placement position is fixed, components, needing to be placed, on a PCB are moved to the positions under a certain suction nozzle through the horizontal movement of a placement platform and the rotation of the placement platform, the suction nozzles lower the components and the placement is achieved.

Description

technical field [0001] The invention relates to electronic component mounting equipment, in particular to an electronic component mounting machine. Background technique [0002] Mounter is a general term for placement equipment in the industry, also known as placement machine, "Surface Mounting System" (Surface Mounting System), is a device used to achieve high-speed, high-precision placement of components, is the entire SMT The most critical and complex equipment in the production line. Mounter is a high-tech mechatronics equipment, mainly composed of computer, ball screw, linear guide, motor, motor drive, optical system, vacuum system and various sensors. [0003] Common placement machines generally have the following types. [0004] 1. Arch type: The component feeding trough and the printed circuit board (PCB) are fixed, and the patch head (installed with several vacuum suction nozzles) reciprocates between the feeding trough and the printed circuit board, and the compo...

AI Technical Summary

Problems solved by technology

The disadvantage is that the reciprocating distance of the placement head is long, and the speed is easily limited

The disadvantage is that there are more restrictions on the type of mounted components, and the price is expensive

The relevant technologies of this type of placement machine have the following deficiencies: 1. The placement head of the arch type placement machine is installed on the beam, drives the motor through the x and y axes to move to the trough area, and then drives the suction nozzle down through the Z axis Retrieving materials requires a large number of axes to be controlled, and the calculation coordinates are in the world coordinate system. The control strategy is complicated and the speed is low; expensive

3. The assembly line operation is generally two groups of placement heads in turn, and the efficiency needs to be improved; the movement of the placement head is relatively large, which is not conducive to the improvement of accuracy
