The invention relates to automatic press fit devices, in particular to an automatic silica gel belt press fit device. The automatic silica gel belt press fit device comprises a feeding belt; a fixing plate is arranged above the feeding belt, a press fit air cylinder is arranged over the fixing plate, and a press fit plate connected with the press fit air cylinder is arranged below the fixing plate; and the feeding belt is provided with front side positioning blocks and back side positioning blocks, and the front side positioning blocks and the back side positioning blocks are all provided with positioning air cylinders. According to the technical scheme provided by the invention, the work that automatic press fitting can be conducted on a silica gel belt adhered to the border of a display screen can be achieved, and moreover, the silica gel belt subjected to press fitting is not prone to being disengaged; and meanwhile, the flatness of the silica gel belt is also ensured, the defect of traditional manual operation is overcome, and the production efficiency of an enterprise is improved.
