Abstract

A pressure maintaining device comprises a bottom plate, a first positioning module and a pressure maintaining module, wherein the first positioning module and the pressure maintaining module are arranged on the bottom plate. The pressure maintaining module comprises a first pressure maintaining air cylinder and a profiling pressing block. The first positioning module comprises a floating plate, limiting columns arranged on the two sides of the floating plate, a first positioning air cylinder fixedly connected with the floating plate, a pair of connecting rod assemblies arranged on one side of the floating plate, and multiple first positioning blocks arranged on the other side of the floating plate. The surfaces, adjacent to the floating plate, of the limiting columns are in a step shape. Each connecting rod assembly comprises a first sliding block, two rotary arms connected to the two sides of the first sliding block in a pivoted manner correspondingly, and two second sliding blocks connected with the two rotary arms in a pivoted manner correspondingly. The first sliding blocks abut against the limiting columns, the first positioning blocks are connected with the second sliding blocks, the first positioning air cylinder is used for driving the floating plate to move in the direction away from or close to the bottom plate, the first sliding blocks drive the second sliding blocks and the first positioning blocks to slide, and accordingly the multiple first positioning blocks can clamp or release workpieces.

Description

technical field [0001] The invention relates to an assembly device, in particular to a pressure-holding device for shell back glue. Background technique [0002] In recent years, consumer electronics products are developing towards miniaturization and ultra-thinness, and the application of conductive adhesives in consumer electronics products is very common and extensive. Usually, the conductive adhesive is attached to the housing of the electronic product, and it needs to be kept under pressure at a certain temperature to enhance the adhesion between the adhesive and the housing and prevent degumming. In addition, there may be stickers attached to the outside of the housing, which also needs to be kept under pressure. Contents of the invention [0003] In view of the above, it is necessary to provide a pressure maintaining device that realizes automatic pressure maintaining. [0004] A pressure-holding device for positioning and pressing workpieces, which includes a bot...
