The invention relates to the technical field of clamps, in particular to a pneumatic type bubble-prevention assembling clamp. The pneumatic type bubble-prevention assembling clamp comprises an upper die plate fixing plate, an upper die plate overturn structure, an upper die plate, a lower die plate and a lower die fixing plate. The upper die plate is movably connected with the upper die plate fixing plate through a rotating shaft, the upper die plate comprises a square-ring-shaped protruding upper die silica gel insert, an upper die plate vacuum absorption locating structure and an upper die gum locating column located in the square-ring-shaped concave part of the upper die silica gel insert, the upper die silica gel insert is provided with one wide edge and three narrow edges, the wide edge cross section in the direction from the wide edge to the corresponding narrow edge is an inclined plane, the lower plate comprises a product locating boss, a lower die plate vacuum absorption locating structure and an upper die gum locating column interworking hole corresponding to the upper die gum locating column, and the lower die plate is fixedly connected to the lower die fixing plate and is connected to an air pressure gauge at the same time. According to the pneumatic type bubble-prevention assembling clamp, accurate bonding and compression of products and gum can be achieved at the same time, gas between the products and the gum can be discharged smoothly in the mode of simulating rolling bonding, and no bubble is generated.
Description
technical field [0001] The invention relates to the technical field of fixtures, in particular to a pneumatic anti-bubble assembly fixture. Background technique [0002] With the development of science and technology, the application of mobile phones has become very common. In order to better protect the shell from damage, the shell of the mobile phone is often assembled with adhesive backing. In the field of production of mobile phone accessories, assembly lines are often used for production. However, when assembling the back glue, in order to ensure the stability of the back glue, two processes are often used for installation. First, the back glue is assembled, and then the assembled back glue is pressed. In the current processing process, the two processes are implemented separately, requiring different operators, increasing the labor cost, and the working time is long, and the production efficiency is not high. [0003] Chinese patent CN202811714U discloses a back glue...
