Portable adjustable sucker

Abstract

The invention discloses a portable adjustable sucker, which consists of an upper sucker and a lower sucker. The upper sucker is provided with an air exhaust slot inside and locking grooves on both sides. Air suction holes (a) are distributed in the bottom plate of the upper sucker. Upper sucker guide slots are arranged on the two sides of the lower part of the bottom plate. The lower sucker is provided with protruding edges on both sides, which are located in the corresponding upper sucker guide slots. Air suction holes (b) are distributed in the bottom plate of the lower sucker. The upper sucker is provided with an upper sucker fixed handle at one end, and the lower sucker is provided with a lower sucker fixed handle at one end. The upper sucker fixed handle is provided with a screw hole(a), and the lower sucker fixed handle is provided with a set of screw holes (b). A fixing screw passes through the screw hole (a) and one of the screw holes (b) to fix the upper and lower suckers. The time for replacement of different types of suckers is saved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a suction cup, in particular to a portable adjustable suction cup used when a flexible circuit board is automatically attached to a covering film. Background technique [0002] In recent years, electronic accessories have generally appeared in various fields, and are updated at the rate of several generations per year. As an important part of electronic accessories, printed circuit boards are also constantly being improved and updated. FPC has become the main development trend of printed circuit boards with its convenience, small size, high density and high performance. With the improvement of people's living standards, there is also a certain degree of requirements for materials, especially for electronic accessories, which not only pay attention to practicality and beauty, but also have higher and higher requirements in terms of volume, integration, and functions of accessories. With the continuous development of the indust...

AI Technical Summary

Problems solved by technology

With the continuous development of the industry, the application fields of FPC continue to increase, and the demand continues to increase; when the flexible circuit board is automatically attached to the cover film, the suction cup will be used. Due to the different sizes of the flexible circuit board, the type of the suction cup needs to be constantly replaced, and if the suction cup If the size is larger than the cover film, air leakage will occur; if the size of the suction cup is smaller than the cover film, the two sides of the cover film will lose the adsorption force
