Assembling device for sealing rings of pens with center refills and method

Abstract

The invention discloses an assembling device for sealing rings of pens with center refills and a method. The assembling device comprises a feeding device, a staggering device and a suction nozzle, the feeding device conveys a sealing ring, the suction nozzle sucks the sealing ring and is connected with a gas source, the staggering device consists of a material carrying seat and a second cylinder which pushes the material carrying seat to move in a staggered manner, the material carrying seat is positioned at one end of the feeding device, and the suction nozzle is arranged above the material carrying seat so as to suck the sealing ring which is arranged on the material carrying seat and needs to be sucked. The direction of staggered movement of the material carrying seat is perpendicular to the feeding direction of the feeding device. The sealing ring which is arranged on the material carrying seat and needs to be sucked moves relative to other sealing rings in a staggered manner, accordingly, the suction nozzle accurately and reliably sucks the sealing ring assuredly, and assembly efficiency of the sealing ring of a pen with a center refill is improved.

Description

technical field [0001] The invention relates to the technical field of automatic assembly of pens, in particular to an automatic assembly device and method for sealing rings of core pens. Background technique [0002] On the cap of the core pen, there are usually a pen clip and a sealing ring that fixes the position of the nib and prevents the ink from evaporating from the nib, such as Figure 1a and 1b As shown, it is the structure of the traditional sealing ring before the improvement, Figure 2a and 2b It is the structure of the improved sealing ring widely used now. [0003] In the existing automatic assembly machine that assembles the pen holder and the sealing ring on the pen cap, when assembling the sealing ring, the linear feeder sends the sealing ring to the material receiving seat, and then the suction nozzle puts the sealing ring on the material receiving seat. The sealing rings are sent to the material receiving seat of the next station one by one to prepare f...

AI Technical Summary

Problems solved by technology

However, since the sealing rings delivered to the material receiving seat by the linear feeder are next to each other, even one part is stacked on top of the other, especially for the sealing ring shown in Figure 2, due to its bottom layer Thinner, it is more likely to overlap each other on the material receiving seat, and the result of this is that the suction nozzle cannot normally absorb the overlapped sealing ring, which greatly reduces the efficiency of assembly
