Description

Technical Field

[0001] The utility model relates to the technical field of touch screens, in particular to an automatic alignment and laminating device for a touch screen. Background Art

[0002] The production process of capacitive touch screen involves a key process, namely the lamination process. The screen can be divided into three parts, namely the protective glass, the touch screen, and the display screen. These three parts need to be laminated. Generally speaking, two laminations are required, one between the protective glass and the touch screen, and the other between the display screen and the touch screen. According to the lamination method, it can be divided into full lamination and frame lamination. At present, the digital devices we use, whether mobile phones, tablets, or notebooks, all use non-full lamination technology, that is, frame lamination;

[0003] When the existing bonding device assembles the touch screen, it is necessary to bond multiple screen components together before pasting. During the bonding process, it is easy to cause the screen component of the previous step to shift, which will affect the production efficiency and quality. Therefore, we have introduced a new touch screen automatic alignment bonding device. Utility Model Content

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. In the utility model, two adsorption mechanisms are arranged in the operating mechanism of the device, and the four micro suction cups in common in the two adsorption mechanisms are respectively distributed at the four corners below the fixed frame at the lower part of the operating mechanism, and two infrared probes are arranged at the lower part of the two adsorption mechanisms. When the device is used, the screen assembly stored in the placement box can be accurately adsorbed out by the four micro suction cups through the four infrared probes, and when the four micro suction cups adsorb the screen assembly outward, the adsorption mechanism will pump a small amount of adhesive into the micro suction cups through a micro pump. When multiple screen assemblies are placed in the assembly slot in sequence, they can be positioned and pasted by a small amount of adhesive in the micro suction cups, so as to prevent the screen assembly from shifting when the adsorption mechanism is removed, and it is also more convenient for the subsequent overall fixation of multiple screen assemblies.

[0027] In this embodiment, the adsorption mechanism 74 includes an adhesive storage box 741, a filling port 742 is provided at the front of the upper end of the adhesive storage box 741, a transparent observation window 743 is provided at the middle of the front end of the adhesive storage box 741, micro pumps 744 are fixedly installed on the rear side of the front end and the rear of the upper end of the adhesive storage box 741, and the output ends of the two micro pumps 744 are fixedly connected to the connecting hoses 745, and the outer surfaces of the two connecting hoses 745 away from the micro pumps 744 are interspersed and fixedly connected with micro suction cups 746. The adhesive storage box 741 and the upper part of the fixed frame 73 are fixedly connected. The two ends are fixedly connected, the two connecting hoses 745 are both inserted and connected with the fixed frame 73, and the two micro suction cups 746 are both located at the two left corners of the lower end or the two right corners of the lower end of the fixed frame 73 and are fixedly connected with the fixed frame 73. By providing an adhesive storage box 741 in the adsorption mechanism 74, when the device is in use, the adsorption mechanism 74 can pump a small amount of adhesive into the two micro suction cups 746 for positioning and pasting the screen assembly, preventing the screen assembly from shifting when the adsorption mechanism 74 is removed, and can more conveniently perform subsequent fixing operations on multiple screen assemblies.
