Description

Pressing die mechanism, upper die jig and pressing equipment Technical Field The present utility model relates to a device for chip packaging, and more particularly to a pressing mechanism, an upper die jig and a pressing device. Background The conventional press-fit device suitable for the chip packaging process is provided with a lower die jig for arranging a plurality of pressed objects in a matrix, and an upper die jig which can be driven to move up and down to be matched with the lower die jig for pressing the pressed objects. The horizontal section of each pressed object is rectangular, and is respectively provided with a substrate, a crystal grain, a thermal interface material and a radiating fin from bottom to top. The upper die jig is provided with die units the same as the pressed objects in number. The compression mould units respectively correspond to the pressed objects up and down. Ideally, the pressing units should respectively press the pressed objects in a straight line downwards in the vertical direction, so that the pressed objects achieve good pressing quality and good packaging quality in the subsequent process. Such as the compression molding unit disclosed in taiwan patent No. I804790. The die unit of the patent I804790 locates a die at the bottom of a pressing rod, and uses a temperature sensing member inserted through the pressing rod and located at the central part of the pressing rod to sense the temperature of the pressed object, which results in fixing the die to the fixing member of the pressing rod and around the temperature sensing member without the position of the temperature sensing member. Disclosure of utility model It is therefore an object of the present utility model to provide a pressing mechanism, an upper die jig and a pressing device, which can overcome at least one of the drawbacks of the related art. The pressing mold mechanism is provided with a sleeving component, a pressing mold component, a lower fixing piece and a temperature sensing piece. The sleeve joint assembly is provided with a shaft rod and a bushing sleeved on the shaft rod. The shaft lever is provided with a through hole penetrating up and down. The bushing is provided with a shaft hole for the shaft rod to pass through. The pressing die assembly is arranged at the bottom end of the shaft lever and is provided with a pressing seat. The lower fixing piece is provided with a first channel communicated with the through hole. The pressing seat is fixed on the through hole by the lower fixing piece. The first channel is used for the temperature sensing element to pass through. The upper die fixture is provided with at least one die pressing mechanism and an upper die base. The upper die base is provided with the same number of setting areas as the at least one die pressing mechanism, and the setting areas are used for setting the at least one die pressing mechanism. The at least one pressing die mechanism is clamped in the setting area by the bushing. The shaft rod can be driven to drive the die assembly to move up and down relative to the upper die base. The pressing device is provided with the upper die jig and a lower die jig matched with the upper die jig for pressing at least one pressed object. The utility model has the beneficial effects that the first channel for the temperature sensing piece to pass through is integrated with the lower fixing piece for fixing the pressing seat on the shaft lever. Besides the structural optimization, the device has the characteristic of simplifying the structure. And, because the upper die jig of the pressing device is provided with the at least one pressing die mechanism, the upper die jig can be matched with the lower die jig to press the pressed object corresponding to the at least one pressing die mechanism, so as to achieve the purpose of the pressing device.
