[0003] In the process of automatic assembly and production of mobile phones, the back cover of the mobile phone is an important accessory among the parts of the mobile phone supporting shell. The automatic assembly process of the back cover of the mobile phone involves the assembly process of multiple groups of auxiliary materials, such as adhesive assembly. The adhesive needs to be attached to the surface of the back cover of the mobile phone to assist in the fixed installation of other accessories such as mobile phone cameras on the back cover of the mobile phone. In the process of automatic adhesive backing of mobile phones, it is necessary to solve the problem of automatic feeding and transportation of the adhesive backing, and because the adhesive layer at the bottom of the adhesive backing is attached with a protective film when the adhesive backing is in the state of incoming material, the protective film at the bottom of the adhesive backing needs to be torn off before the subsequent adhesive backing can be performed, so the adhesive backing film tearing problem also needs to be solved; in addition, the adhesive backing is a sheet structure, and the adhesive backing needs to be supplied in batches to ensure the efficiency of automation. Generally, a material box is used as a storage mechanism, and multiple pieces of adhesive backing are stored in a stacked manner for the material taking mechanism to take the material piece by piece.

[0017] The utility model aims to provide a method for realizing automatic feeding of adhesive backing in an automatic assembly production line of mobile phones. Specifically, a material box space formed by a movable material box component is used to store multiple pieces of adhesive backing in a stacked manner.

The power output by the ejector rod drives the load-bearing plate to synchronously move upwards with the thickness of a piece of glue as the movement distance unit during the material taking process, so as to compensate for the height difference of the glue caused by taking out a piece of glue each time, so that the height of the uppermost layer of glue on the load-bearing plate is always maintained unchanged, thereby accurately controlling the glue taking out The material height is ensured to ensure the accuracy of adhesive backing material picking; and the four push rods that pass through the bottom plate of the movable material box assembly upwards can not only play the role of lifting the load-bearing plate, but also effectively limit the bottom plate, ensuring its position stability in the installation slide groove, avoiding position displacement caused by actions such as material picking, thereby ensuring the accuracy of the adhesive backing position; in the process of taking and placing materials, the four push rods pass through the through holes opened on the load-bearing support plate and the bottom plate to support the load-bearing plate upward, and are detachably connected and fixed with the four adsorption blocks at the bottom of the load-bearing plate (the adsorption blocks can be magnetic blocks, which adsorb the push rods by magnetic force); when the material in the material box space is taken out, the push rod descends, and after separating from the adsorption block, it descends downward from the through hole to the bottom of the load-bearing support plate to avoid movement interference when sliding in or pulling out the movable material box assembly. The utility model uses a conveying mechanism arranged on the side of the movable material box component as a material taking execution component. After the conveying mechanism takes out the adhesive sheet from the material box space piece by piece, it performs multi-piece detection at the multi-piece detection component. The qualified materials are conveyed to the film tearing component, and the film tearing component clamps the protective film at the bottom of the suspended and adsorbed adhesive sheet and then tears it downward; the adhesive sheet after film tearing is further conveyed to the transfer platform by the conveying mechanism and placed on the transfer platform for transfer or shooting positioning and other actions. At the same time, the transfer platform includes a transfer motor with the output end vertically upwardly arranged, and the position or angle of the adhesive sheet placed thereon can be fine-tuned and corrected by the transfer motor to ensure the position accuracy when it is attached to the back cover of the mobile phone.

The movable material box assembly forms a material box space with an opening at the top through a first side plate, a second side plate and a guide rod vertically arranged on the bottom plate, and uses a load-bearing plate that can move freely in the vertical direction as a glue bearing structure. The jacking mechanism arranged under the load-bearing assembly outputs power to simultaneously drive four ejector rods to pass through the load-bearing support plate of the load-bearing assembly and the bottom plate of the movable material box assembly to extend into the material box space, and is detachably connected to the bottom of the load-bearing plate through an adsorption block. The power output by the ejector rod drives the load-bearing plate to synchronously move upwards with the thickness of a piece of glue as the movement distance unit during the material taking process, so as to compensate for the height difference of the glue caused by taking out a piece of glue each time, so that the height of the uppermost layer of glue on the load-bearing plate is always maintained unchanged, thereby accurately controlling the glue taking out The material height is ensured to ensure the accuracy of adhesive backing material picking; and the four push rods that pass through the bottom plate of the movable material box assembly upwards can not only play the role of lifting the load-bearing plate, but also effectively limit the bottom plate, ensuring its position stability in the installation slide groove, avoiding position displacement caused by actions such as material picking, thereby ensuring the accuracy of the adhesive backing position; in the process of taking and placing materials, the four push rods pass through the through holes opened on the load-bearing support plate and the bottom plate to support the load-bearing plate upward, and are detachably connected and fixed with the four adsorption blocks at the bottom of the load-bearing plate (the adsorption blocks can be magnetic blocks, which adsorb the push rods by magnetic force); when the material in the material box space is taken out, the push rod descends, and after separating from the adsorption block, it descends downward from the through hole to the bottom of the load-bearing support plate to avoid movement interference when sliding in or pulling out the movable material box assembly.The utility model uses a conveying mechanism arranged on the side of the movable material box component as a material taking execution component. After the conveying mechanism takes out the adhesive sheet from the material box space piece by piece, it performs multi-piece detection at the multi-piece detection component. The qualified materials are conveyed to the film tearing component, and the film tearing component clamps the protective film at the bottom of the suspended and adsorbed adhesive sheet and then tears it downward; the adhesive sheet after film tearing is further conveyed to the transfer platform by the conveying mechanism and placed on the transfer platform for transfer or shooting positioning and other actions. At the same time, the transfer platform includes a transfer motor with the output end vertically upwardly arranged, and the position or angle of the adhesive sheet placed thereon can be fine-tuned and corrected by the transfer motor to ensure the position accuracy when it is attached to the back cover of the mobile phone.

[0043] The embodiments of the utility model are only to introduce its specific implementation methods and are not intended to limit its protection scope. The technicians in this industry can make some modifications inspired by the embodiments, so any equivalent changes or modifications made in accordance with the scope of the utility model patent are within the scope of the claims of the utility model patent.
