Automatic pitch changing mechanism

Abstract

The invention discloses an automatic pitch changing mechanism which comprises a plurality of X pitch changing driving modules, at least one Y pitch changing driving module, a plurality of rows of suction rod modules, a plurality of X pitch changing modules and a plurality of Y pitch changing modules. Each row of suction rod modules comprises a plurality of suction rod modules which are arranged at intervals, and the suction rod modules in the same row are connected through an X variable pitch module; the Y variable-pitch module is arranged in the length direction perpendicular to the X variable-pitch module and used for being connected with the suction rod modules in different rows. Each X variable-pitch module is driven by at least one X variable-pitch driving module and is used for driving the suction rod modules in the same row to adjust the spacing; and at least one Y variable-pitch module is driven by a Y variable-pitch driving module and is used for driving the suction rod modules in different rows to adjust the spacing. The device is light in structure and easy to implement, multi-stage pitch changing can be completed by driving the pitch changing pull rod to move, efficiency is higher, assembling and maintaining are easy, debugging is easy, the number of universal parts is large, and therefore the machining cost is low.

Description

technical field [0001] The invention relates to the technical field of keyboard assembly, in particular to an automatic distance changing mechanism. Background technique [0002] In the assembly process of the keyboard, it is generally necessary to install the keycaps on the paint spraying vehicle first for the painting process. After the painting is completed, the keycaps are removed from the painting vehicle and then installed on the keyboard bottom plate. Due to the different sizes or types of keyboards, the distance between the keycaps is different, but the spray paint carrier can only be used for one size or type of keyboard. The management of the production line is difficult, and it brings certain operational complexity to the production of the switching line. Therefore, a pitch-change mechanism for picking and placing keycaps with inconsistent distances between the paint spraying vehicle and the keyboard bottom plate came into being. [0003] The existing pitch chan...

Problems solved by technology

[0003] The existing pitch-changing mechanism takes up a lot of space and is heavy, and the processed parts cannot be used universally, which leads to high processing costs. There are too many precision parts processed, which is not conducive to maintenance, and it is impossible to realize the pitch-changing of the keycaps on the entire paint-spraying carrier, resulting in subsequent machine failures. Need to deal with keycaps that cannot be changed
