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, and in particular to a device and method for automatic assembly of a spring in a correction fluid pen tip. Background technique [0002] At present, correction fluid pens have been widely used in study and work. In the production of correction fluid pens, after the components are produced separately, the next important step is to assemble these components. At present, the assembly of the correction fluid pen mainly adopts automated assembly, that is, assembly on an automated assembly machine. [0003] Such as figure 1 Shown is a common correction fluid pen, which includes a pen barrel and a pen tip 9 mounted on the pen barrel. A correction fluid tube (not shown) is installed in the pen barrel. The pen tip 9 includes a needle bar 92 and a spring set on the needle bar. 91. The limit sleeve 93 and the outer casing 94 installed outside the spring 91, the needle bar 92, the sp...

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
