Novel material suction nozzle device

Abstract

The invention discloses a novel material suction nozzle device. The speed of replacing the suction nozzle is extremely fast, the fitting precision is extremely high, and a series of actions of grasping, correcting and mounting the material are quickly completed. All motors, Mini-products can be used for the guide and all parts, the entire suction nozzle unit occupies a compact space, almost on thesame order of magnitude as commonly used material sizes, A suction nozzle device comprise a main bracket, a vertical power device, a guide rail and a suction nozzle device with a suction nozzle motor, a slide rail part of that guide rail is vertically arrange on the main bracket, a vertical power device is arranged on a slide block part of the guide rail, and the vertical power device can slide up and down on the slide rail part along with the slide block part; A suction nozzle device is arrange on a vertical power device, that vertical pow device can drive the suction nozzle device to move up and down, and a suction nozzle motor can drive the suction nozzle device to make a rotational motion in a horizontal direction. The invention relates to the technical field of SMT mounting.

Description

technical field [0001] The invention relates to the technical field of SMT placement, in particular to a novel material suction nozzle device. Background technique [0002] In the existing technology, material placement is the last process of the SMT production line. The speed and accuracy of its placement are facing challenges under the rapid growth of the 3C market and the trend of miniaturization of PCBA structure design. [0003] The suction nozzle device is one of the key components in the material placement process. The basic functional requirements are to quickly approach the material retrieving, correct the material posture, and place it according to the height of the placement point. Its movement speed and accuracy become the test. The most important indicator of process capability. Traditional suction nozzles mostly use sliding table cylinder, ball screw, belt drive, etc. These designs may not be able to carry multiple suction nozzles due to uncontrollable speed a...

AI Technical Summary

Problems solved by technology

Traditional suction nozzles mostly use sliding table cylinder, ball screw, belt drive, etc. These designs may not be able to carry multiple suction nozzles due to uncontrollable speed and height, or due to their large size and weight. Therefore, an SMT production line usually requires multiple suction nozzles. The machines work in parallel, the number of material flows is high, and the failure rate is high. Therefore, there is an urgent need for a solution with compact structure, large stroke, fast speed and high precision for material placement.
