Description

Split type heating pressurize tool platform and pressurize equipment

Technical Field

Background

In the manufacturing process of electronic devices, two parts are generally required to be bonded by hot melt adhesive, and in the bonding process, the parts are generally required to be heated and pressurized by pressure maintaining equipment, so that the two parts are bonded and fixed after the hot melt adhesive is melted.

In the related art, the parts are heated and pressurized by the pressure maintaining device, but the upper pressurizing and heating device is usually used to press down on the jig, so as to heat and pressurize the two parts on the jig, that is, to heat the two parts from the upper side to the lower side. For example, in the back plate of some mobile phones, a sheet-shaped part (such as an SP plate) is adhered to the inner surface of the back plate through a hot melt adhesive, and when the back plate is heated from the top down, the upper layer of the hot melt adhesive melts first, and the part of the lower layer, which is in contact with the back plate, melts slowly and unevenly, so that the adhesion is not firm, and the flatness is also affected.

In addition, many electronic apparatuses generally have a camera module, and some electronic apparatuses have a camera module protruding from an apparatus case. For example, in some mobile phones, in order to adapt to a protruding camera module, a lens area on a back plate corresponding to the camera module protrudes downward. When the back plate of these mobile phones needs to be bonded to other parts (for example, a sheet-like workpiece is bonded to the inner surface of the back plate), since the bottom surface of the back plate and the lens region are not on the same plane, the lens region cannot be reliably supported when the back plate is subjected to pressure holding, and further, the lens region is pressed little during the pressure holding process, so that the back plate and other parts are bonded unevenly, and the flatness is poor.
