Device and method for assembling spring in correction fluid pen point

Abstract

The invention discloses a device and method for assembling a spring in a correction fluid pen point, which are used for assembling the spring into a stop collar of the correction fluid pen point. The assembling device is one part of correction fluid automatic assembling equipment and comprises an upper sliding part, a lower sliding part connected with the upper sliding part, a pushing part which is used for pushing the upper sliding part and the lower sliding part to slide, a load support which is used for accommodating the stop collar and a mandril part which is arranged above the load support and used for pushing the spring into the load support, wherein the upper sliding part is fixedly connected with the pushing part, the upper sliding part is provided with a first through hole, and the lower sliding part is provided with a second through hole. According to the assembling device disclosed by the invention, the spring can be reliably assembled into the stop collar in the correctionfluid pen point on the load support, assembling quality and reliability of the spring in the correction fluid pen point are greatly improved, defective products during assembling are reduced, and integrated assembling efficiency of a correction fluid pen is improved.

Description

technical field [0001] The invention relates to the technical field of automatic assembly of correction fluid, in particular to an automatic assembly device and method for an inner spring of a correction fluid nib. Background technique [0002] At present, correction fluid pens are widely used in study and work, and in the production of correction fluid pens, after each component is produced separately, the next very important step is to assemble these components. At present, the assembly of the correction fluid pen mainly adopts automatic assembly, that is, it is assembled on an automatic assembly machine. [0003] Such as figure 1 Shown is a common correction fluid pen, which includes a pen holder and a nib 9 installed on the pen holder. The pen holder is equipped with a correction fluid tube (not shown in the figure), and the nib 9 includes a needle rod 92 and a spring sleeved on the needle rod. 91. The limit sleeve 93 and the outer casing 94 installed outside the sprin...

AI Technical Summary

Problems solved by technology

[0004] However existing assemblies such as figure 1 In the automatic assembly equipment for the correction fluid pen shown, the spring in the correction fluid pen head is directly dropped from the position directly above the position of the correction fluid stopper and the needle bar, and since the stopper itself is relatively small, There is often a certain deviation between the ideal position of the spring, the limit sleeve and the needle bar. Therefore, the spring installation deviation often occurs, which not only reduces the yield and efficiency of the spring installation, but also affects the entire correction fluid pen. assembly yield and efficiency
