Suction means and lens module assembling apparatus

Abstract

The present invention provides a suction device, which includes a tube body and a suction source communicating with the tube body. The tube body has a suction end port for sucking a component, wherein the outer wall of the tube body is provided with ventilative grooves. The suction device is suitable for being arranged on an assembling device such as a lens module assembling device, and is in particular suitable for assembling a small and light component needing to be assembled in a holding space. The suction device can ensure air in the holding space to communicate with the outside, and then can ensure the variety of the air pressure in the holding space to be less; and then the suction device can position the small and light component accurately, and can ensure the positioned components not to shift.

Description

technical field [0001] The invention relates to a suction device, and to a lens module assembly equipment with the suction device. Background technique [0002] In the assembly equipment of various products, the suction device is often used to hold the components to be assembled and assemble them on the proper position of the product. The suction device usually has a tube body and a suction source, the tube body communicates with the suction source, through the action of the suction source, the tube body holds a component at a suction port, and then moves to the assembly position Place the component. When the suction device sucks and assembles components of a certain specification, the size of the suction port of the tube body is usually smaller than the surface size of the component, so as to accurately suck and assemble it. [0003] However, some products and the components used therein, for example, the lens module components and the lens barrel used in the miniaturized...

AI Technical Summary

Problems solved by technology

When the suction device is used to hold this type of lens module components and assemble them into the lens barrel, especially when lens module components have been assembled in the lens barrel, the gas in the lens barrel will be compressed to cause the gas pressure to rise. It is difficult to make the small and light lens module components drift and cause inaccurate positioning

In addition, when the suction device is pulled out from the lens barrel, the reduction of gas pressure inside the lens barrel may also cause the lens module components to move.
