Positioning mechanism for assembling keycap

Abstract

The invention discloses a positioning mechanism for assembling a keycap. The mechanism comprises a supporting seat through which a conveying line passes, a pressing plate fixed to the supporting seat,a positioning cover plate which is fixed to the pressing plate and performs the secondary positioning of the keycap, and a jacking plate which is located below the pressing plate, jacks a jig bearingthe keycap upwards and abuts against the pressing plate. A plurality of positioning openings allowing the keycap to stretch out are formed in the positioning cover plate. The keycap on the paint spraying jig is directly subjected to secondary positioning, thereby achieving direct butt joint with a paint spraying assembly line, reducing the assembly process, and improving the assembly efficiency and the assembly precision.

Description

【Technical field】 [0001] The invention belongs to the technical field of keyboard assembly, in particular to a positioning mechanism for keycap assembly. 【Background technique】 [0002] As far as current personal computer usage habits are concerned, the keyboard is one of the indispensable input devices for inputting characters, symbols or numbers. Not only that, but all consumer electronic products in daily life or large-scale processing equipment used in the industry need to be equipped with a key structure as an input device to operate the above-mentioned electronic products and processing equipment. [0003] Generally speaking, most of the keys on the keyboard device are keys with square keycaps, and a small number of keys such as space key (SPACE), input key (Enter), large character key (Caps Lock), shift key (Shift), etc. The length of the keycap is greater than the width, and this type of key is called a multiple key. [0004] After injection molding, keycaps need t...

AI Technical Summary

Problems solved by technology

[0004] After injection molding, keycaps need to be sprayed and dried before they can be assembled, and then in the step of spraying and drying, in the prior art, all keycaps are generally placed on a carrier jig for painting. The automatic assembly of the keycap requires very high positional accuracy. Therefore, after the keycap is painted on the painting fixture, its positional accuracy cannot meet the precision requirements of the automatic assembly. Therefore, when the company first started, it was Take the keycaps on the paint jig out of the jig and place them on a keycap template with more precise positioning, then put the keycap template on the assembly line and transport it to the assembly station, and the manipulator removes it from the keycap template The keycap realizes automatic assembly; however, the intermediate transfer process of the keycap will lead to an extension of the assembly efficiency, and the assembly process steps will also increase, reducing the production efficiency, and it is necessary to add one or more manipulators, which increases the assembly cost
