The traditional way to bond the mobile phone touch screen is to manually hold the mobile phone touch screen against the mobile phone frame for alignment and bonding, and then put it into a pressing machine for a certain period of time to ensure that the hot melt glue between the mobile phone touch screen and the mobile phone frame flows evenly, so that the mobile phone touch screen and the mobile phone frame are completely bonded in place. However, this method is not only labor-efficient, but also may cause the problem of unstable and inaccurate positioning of the mobile phone touch screen, which is difficult to meet the requirements of modern mobile phone manufacturing for the bonding accuracy of the touch screen and the mobile phone frame.

[0003] Therefore, in the prior art, a single-station touch screen alignment device is introduced, which completes the alignment of the mobile phone touch screen and the mobile phone middle frame through the alignment device, and is manually taken out and placed on a conveyor belt, and then conveyed to the next station, and then manually taken out and placed in a press machine for pressing. However, the alignment and pressing of the mobile phone touch screen are performed at two stations respectively, the production line is relatively long, and there are many operations. Before the hot melt adhesive is completely solidified, the touch screen is prone to displacement.

The contoured upper tooling 64 and the contoured lower tooling 30 enclose and define a pressing cavity, and the pressing cavity matches the shape of the mobile phone touch screen 44 and the mobile phone middle frame 31 after pressing and installation. Therefore, the pressing driver 62 drives the second lifting plate 63 to drive the contoured upper tooling 64 to descend, so as to maintain the pressure and press the mobile phone touch screen and the mobile phone middle frame after pressing, so that the hot melt adhesive between the mobile phone touch screen and the mobile phone middle frame is evenly spread and the two are completely fitted in place. In this embodiment, the pressing driver 62 is a lifting cylinder. Of course, in other practicable embodiments, the pressing driver 62 may be an electric push rod.

[0061] Further, the second support frame 61 includes a first support plate 611 and a plurality of second support columns 612, the second support plate 611 is arranged above the mounting plate 10 through the second support columns 612, the pressing driver 62 is installed on the second support plate 611, the second lifting plate 63 includes a second connecting portion and a second extending portion, the output end of the pressing driver 62 is movably arranged in the second support plate 611 along the vertical direction, and is connected to the second connecting portion of the second lifting plate 63, the second extending portion is the two ends of the first connecting portion extending outward along the length direction thereof, and the second extending portion is movably connected to the second support column 612 along the vertical direction. Thus, through the design of the movably connected second lifting plate and the second support column, the movement of the second lifting plate in the vertical direction is more stable. Preferably, the number of the second support columns is four, which are respectively arranged at the four corners of the second support plate. Of course, in other replaceable embodiments, the number of the second support columns is not limited to four, and can be two, or six, or more than six.

[0062] Furthermore, the second extension of the second lifting plate 63 is provided with a second through hole at a position corresponding to the second support column 612, and a sleeve is provided in the second through hole, and the second lifting plate 63 is movably connected to the second support column 611 in the vertical direction through the sleeve. Thus, the movement of the second lifting plate is more stable and smooth through the movability of the sleeve and the second support column.

[0063] In this embodiment, the upper profiling tooling 64 is provided with a pressing guide column 641 on the surface facing the lower profiling tooling, and the lower profiling tooling 64 is provided with a pressing guide hole 32 at a position corresponding to the pressing guide column 641. Thus, through the cooperation of the pressing guide column 641 and the pressing guide hole 32, the upper profiling tooling 64 is precisely aligned with the lower profiling tooling 30 to ensure the pressing accuracy of the pressing.

[0064] In this embodiment, the pressing mechanism 60 further includes a pressure gauge 65, which is disposed between the output end of the pressing driver and the second lifting plate. Thus, the pressure gauge transmits pressure data in real time to ensure that the mobile phone touch screen and the mobile phone middle frame are pressed together under standard pressure.

[0065] In this embodiment, the mobile phone touch screen pressing device further includes a control component, and the control component is electrically connected to the conveying mechanism, the touch screen bearing and positioning mechanism, the pressing mechanism and the pressing mechanism respectively.

[0066] Before use, adjust the overall position of the bearing positioning assembly and the mobile phone touch screen through the bearing positioning adjustment platform to accurately align the mobile phone touch screen with the mobile phone middle frame. When in use, the production worker puts the mobile phone middle frame into the contoured lower tooling, puts the mobile phone touch screen into the mobile phone touch screen bearing positioning mechanism, starts the mobile phone touch screen pressing device, and the stroke driver of the pressing mechanism drives the adsorption tooling to descend. When it descends to the position of the mobile phone touch screen, the limit driver is started, and its output end abuts against the limit plate, so that the adsorption tooling pauses at the position of the mobile phone touch screen and adheres and adsorbs the mobile phone touch screen. At the same time, the bearing positioning driver drives the two bearing positioning parts to move away from each other to release the mobile phone touch screen. Then, the limit driver is started again, and its output end moves in the opposite direction to disengage from the limit plate, so that the adsorption tooling adsorbing the mobile phone touch screen continues to descend, so as to press the mobile phone touch screen into the mobile phone middle frame;

[0067] The conveying mechanism conveys the pressed mobile phone touch screen and mobile phone middle frame to the second workstation, and the pressing driver drives the contoured upper tooling to descend, so as to maintain the pressure and press the mobile phone touch screen and mobile phone middle frame for a certain period of time, so that the hot melt adhesive between the mobile phone touch screen and the mobile phone middle frame flows evenly and the two are completely fitted in place. Finally, the production staff takes out the pressed mobile phone touch screen and mobile phone middle frame.

[0068] Compared with the prior art, the mobile phone touch screen pressing device provided by the present invention sets a mobile phone touch screen carrying positioning mechanism and a pressing mechanism at the first station, sets a pressing mechanism at the second station, and sets a conveying mechanism between the first station and the second station. The mobile phone touch screen carrying positioning mechanism at the first station realizes the active carrying of the mobile phone touch screen and the precise alignment of the mobile phone touch screen and the mobile phone middle frame. The mobile phone touch screen is sucked and pressed by the pressing mechanism, and the pressed mobile phone touch and the mobile phone middle frame are conveyed to the second station by the conveying mechanism, and then the pressed mobile phone touch screen and the mobile phone middle frame are aligned by the pressing mechanism. The pressure-holding and pressing are performed for a certain period of time, so as to realize the alignment, lamination and pressure-holding pressing of the mobile phone touch screen and the mobile phone middle frame. Through the above arrangement, the two processes of alignment, lamination and pressure-holding pressing of the mobile phone touch screen and the mobile phone middle frame are integrated into one device, which saves space while realizing the precise alignment and assembly of the mobile phone touch screen and the mobile phone middle frame, helps to shorten the production line, and avoids the problem of touch screen displacement before the hot melt adhesive is completely solidified due to the long transmission line and many operations. In addition, the process integration can streamline the personnel and save labor costs. Further, the controller can realize automatic alignment and pressing, thereby improving the automation level of the production line.
