Split type heating and pressure maintaining jig table and pressure maintaining equipment

Abstract

The invention discloses a split type heating and pressure maintaining jig table and pressure maintaining equipment. The split type heating and pressure maintaining jig table comprises a jig base, a first heating rod, a lens floating supporting table and a second heating rod, wherein the jig base is provided with a bearing surface suitable for bearing an equipment shell, and an assembling groove is arranged at a position, corresponding to a lens area on the equipment shell, of the bearing surface; the first heating rod is arranged in the jig base and is used for heating the jig base; the lens floating supporting table is embedded in the assembling groove and can elastically float in a vertical direction, and when the equipment shell is pressed to be attached to the bearing surface, the lens floating supporting table elastically abuts against the lens area; and the second heating rod is arranged on the lens floating supporting table and is used for heating the lens floating supporting table. According to the split type heating and pressure maintaining jig table provided by the invention, an upper face and a lower face of hot melt adhesive can be heated at the same time, it can be ensured that the hot melt adhesive is evenly melted, heating is even, bonding is firm and reliable, and flatness is high.

Description

technical field [0001] The invention relates to pressure maintaining equipment, in particular to a split heating and pressure maintaining fixture table and pressure maintaining equipment. Background technique [0002] In the processing and manufacturing of electronic equipment, it is usually necessary to bond two parts with hot melt adhesive. In this bonding process, it is usually necessary to use pressure holding equipment to heat and press the parts so that the hot melt The two parts are glued together. [0003] In the related art, the pressure holding equipment is used to heat and press the parts, but usually, the upper pressurization and heating equipment is used to press down on the jig, and the two parts on the jig are heated and pressurized, that is, , heating from top to bottom. For example, on the backboard of some mobile phones, a piece of parts (such as SP board) is bonded by hot melt adhesive on the inner surface of the backboard. When heating from the top to t...

AI Technical Summary

Problems solved by technology

When the back plates of these mobile phones need to be bonded with other parts (such as bonding a piece of workpiece on the inner surface of the back plate), since the bottom surface of the back plate is not in the same plane as the lens area, when the back plate is kept under pressure, The lens area cannot be reliably supported, resulting in less pressure on the lens area during the pressure holding process, resulting in uneven bonding between the back plate and other parts, and poor flatness
