A pressing device for electronic products protected by electrorheological fluid

Abstract

The invention relates to the technical field of electronic product processing equipment, and discloses a pressing device for electronic products protected by electrorheological fluid, including a sliding frame, a pressing plate and a support table, the pressing plate is located on the top of the sliding frame, and the The support platform is located inside the sliding frame, and the bottom of the sliding frame is slidably connected with a sliding plate. There are four sliding frames in total; the upward supporting force is lost, thereby achieving the purpose of protecting electronic products. In addition, the current There are two symmetrical positive and negative electrodes in the variable fluid, and the two electrodes correspond to two enamelled copper columns and two conductive sleeves. When the pressing surface is inclined, the exposed ends on the two enamelled copper columns cannot At the same time, it is in contact with two conductive sleeves, so that the electrodes in the electrorheological fluid cannot form a path, and then when the pressing surface is inclined, it can also achieve the purpose of protecting electronic products, greatly improving the electronic products during the pressing process. yield rate.

Description

technical field [0001] The invention relates to the technical field of electronic product processing equipment, in particular to an electronic product pressing device protected by electrorheological fluid. Background technique [0002] At present, as electronic products become more and more diversified, the requirements for the production and manufacture of electronic products are getting higher and higher. Precise and stable pressing operations for PCB boards and wiring harnesses. [0003] In the prior art, when pressing parts requiring high lamination precision such as chips or PCB boards, since electronic products are directly pressed by the lamination board on the support table, when the lamination force is too large or the lamination angle appears When tilted, electronic products are easily damaged by excessive pressure, which leads to an increase in the rate of defective products. In addition, during the pressing process, due to the effect of pressure, electronic prod...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a pressing device for electronic products protected by electrorheological fluid, which protects electronic products by using electrorheological fluid. When the pressure is too high or the pressing surface is tilted, it will automatically Reduce the pressure on the electronic product and convert the downward force into a lateral clamping force, clamp the electronic product, avoid its movement and shaking, and solve the problem when the pressing force is too large or the pressing angle is inclined , electronic products are easily damaged by excessive pressure, which leads to an increase in the rate of defective products. In addition, during the pressing process, due to the effect of pressure, electronic products are prone to move, which further increases the rate of defective products, thereby increasing The processing cost of electronic products
