[0002] Among the many processes involved in mobile phone manufacturing, centering the touchscreen on the phone's midframe is a crucial step. Traditionally, the touchscreen is manually aligned against the midframe, then placed in a laminating machine for a specific period of time to ensure even hot melt adhesive flow between the touchscreen and the midframe, ultimately achieving a complete fit. However, this method is not only labor-intensive but can also lead to unstable and inaccurate positioning of the touchscreen, making it difficult to meet the precision requirements of modern mobile phone manufacturing for touchscreen-to-midframe lamination.

[0003] Therefore, existing technology has introduced single-station touch screen alignment equipment, which aligns the mobile phone touch screen with the phone's midframe. The touch screen is then manually removed and placed on a conveyor belt, transported to the next station, and then manually placed on a laminating machine for lamination. However, the alignment and lamination of the mobile phone touch screen are performed at two separate stations, resulting in a long production line and numerous operations. This makes it easy for the touch screen to shift before the hot melt adhesive has fully solidified. Furthermore, the entire mobile phone touch screen assembly process requires two sets of equipment and two people to operate, resulting in high equipment and labor costs. Summary of the Invention

The extension portion extends outward along the length of the connecting portion at both ends and is vertically movable to the first support columns 512. Thus, by designing the extension portion on the first lifting plate 541 to be movably connected to the first support columns 511, the vertical movement of the first lifting plate 541 is more stable, thereby ensuring the accuracy of the press-fitting of the mobile phone touch screen and the mobile phone midframe. Preferably, there are four first support columns 512, each located at the four corners of the first support plate 511. Of course, in other alternative embodiments, the number of the first support columns 512 is not limited to four, and can be two, six, or more than six.

[0057] Furthermore, the first support plate 511 is provided with a first guide hole at a position corresponding to the first guide column 542, and a sleeve is provided in the first guide hole, and the first support plate 511 is movably connected to the first guide column 542 through the sleeve. Thus, the stability of the movement of the adsorption tooling 55 and the first lifting plate 541 is improved by the design of the first guide column 542. Preferably, the number of the first guide columns 542 is four, and the four first guide columns 542 are arranged in a matrix in the middle of the first support plate 511. Of course, in other alternative embodiments, the number of the first guide columns 542 is not limited to four, and can be two, or six, or more than six.

[0058] Furthermore, the extension portion of the first lifting plate 541 is provided with a through hole at a position corresponding to the first support column 512. A sleeve is disposed in the through hole, and the first lifting plate 541 is movably connected to the first support column 512 via the sleeve. Thus, the cooperation between the sleeve and the first support column 511 makes the movement of the first lifting plate 541 more stable and smooth.

[0059] Preferably, the stroke driver 52 is a lifting cylinder, and the limit driver 53 is a limit cylinder. The cylinder body of the lifting cylinder is vertically mounted on the first support plate 511 through the limit plate 543, and the output end of the lifting cylinder passes through the first support plate 511 and is connected to the first lifting plate 541. The limit cylinder is disposed between the first support plate 511 and the limit plate 543, and the cylinder body of the limit cylinder is vertically mounted on the first support plate 511. The output end of the limit cylinder is disposed toward the limit plate 543 and movably abuts against the limit plate 543. Of course, in other alternative embodiments, the stroke driver 52 may be an electric push rod, and the limit driver 53 may be an electric push rod.

[0060] Please also see Figure 14 , Figure 14The schematic diagram of the structure of the pressing mechanism described in Example 1 of the present invention is shown. The pressing mechanism 60 includes a second support frame 51, a second lifting plate 63, a contoured upper tooling 64, and a pressing driver 62. The second support frame 51 is mounted on the mounting plate 10, and the pressing driver 62 is mounted on the second support frame 51. The upper surface of the second lifting plate 63 is connected to the output end of the pressing driver 62, and the lower surface of the second lifting plate 63 is connected to the contoured upper tooling 64. The contoured upper tooling 64 and the contoured lower tooling 30 enclose and define a pressing cavity. The pressing cavity matches the shape of the mobile phone touch screen 44 and the mobile phone middle frame 31 after pressing and installing. Thus, the pressing driver 62 drives the second lifting plate 63 to lower the contoured upper tooling 64, thereby maintaining pressure and pressing the press-fitted mobile phone touch screen and mobile phone middle frame together. This ensures that the hot melt adhesive between the mobile phone touch screen and the mobile phone middle frame flows evenly and fits the two together perfectly. 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] Furthermore, 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 positioned above the mounting plate 10 via the second support columns 612. The press-fit actuator 62 is mounted on the second support plate 611. The second lifting plate 63 includes a second connecting portion and a second extension. The output end of the press-fit actuator 62 is vertically movable through the second support plate 611 and connected to the second connecting portion of the second lifting plate 63. The second extensions extend outward from both ends of the first connecting portion along its length, and the second extensions are vertically movable to the second support columns 612. Thus, the design of the movable connection between the second lifting plate and the second support columns makes the vertical movement of the second lifting plate smoother. Preferably, the number of second support columns is four, respectively disposed at the four corners of the second support plate. Of course, in other alternative embodiments, the number of second support columns is not limited to four and can be two, six, or more.

[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. A sleeve is disposed in the second through-hole, through which the second lifting plate 63 is vertically movably connected to the second support column 611. Thus, the movable cooperation between the sleeve and the second support column makes the movement of the second lifting plate more stable and smooth.

[0063] In this embodiment, the surface of the upper profiling tooling 64 facing the lower profiling tooling is provided with a press-fitting guide post 641, and the lower profiling tooling 64 is provided with a press-fitting guide hole 32 at a position corresponding to the press-fitting guide post 641. Thus, through the cooperation between the press-fitting guide post 641 and the press-fitting guide hole 32, the upper profiling tooling 64 and the lower profiling tooling 30 are precisely aligned and matched, thereby ensuring the pressing accuracy during the downward pressing.

[0064] In this embodiment, the pressing mechanism 60 further includes a pressure gauge 65, which is disposed between the output terminal of the pressing driver and the second lifting plate. Thus, the pressure gauge transmits pressure data in real time to ensure that the touch screen and the midframe of the mobile phone 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 carrying and positioning mechanism, the pressing mechanism and the pressing mechanism respectively.

[0066] Before use, the overall position of the bearing positioning assembly and the mobile phone touch screen is adjusted through the bearing positioning adjustment platform to accurately align the mobile phone touch screen with the mobile phone middle frame. During use, the production worker places the mobile phone middle frame into the contoured lower tooling, places the mobile phone touch screen into the mobile phone touch screen bearing positioning mechanism, and starts the mobile phone touch screen pressing device. 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 activated, and its output end abuts against the limit plate, causing the adsorption tooling to pause at the position of the mobile phone touch screen and adhere 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 activated again, and its output end moves in the opposite direction to disengage from the limit plate, causing the adsorption tooling adsorbing the mobile phone touch screen to continue to descend, so as to press the mobile phone touch screen onto the mobile phone middle frame.

[0067] The conveying mechanism transports the pressed mobile phone touch screen and mobile phone middle frame to the second workstation. The pressing driver drives the contoured upper tooling to descend to maintain 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 into place. Finally, the production worker takes out the pressed mobile phone touch screen and mobile phone middle frame.

[0068] Compared with the prior art, the mobile phone touch screen compression device provided by the utility model realizes the active bearing of the mobile phone touch screen and the accurate alignment of the mobile phone touch screen and the mobile phone middle frame through the mobile phone touch screen bearing and positioning mechanism of the first station, realizes the suction and compression of the mobile phone touch screen through the compression mechanism, then the mobile phone touch screen and the mobile phone middle frame after compression are conveyed to the second station through the conveying mechanism, and the mobile phone touch screen and the mobile phone middle frame after compression are pressure-maintained and compressed for a certain time through the compression mechanism, so that the alignment and lamination of the mobile phone touch screen and the mobile phone middle frame are realized, the two processes of alignment and lamination and pressure-maintenance and compression of the mobile phone touch screen and the mobile phone middle frame are integrated on one equipment, the space is saved while realizing the accurate alignment and assembly of the mobile phone touch screen and the mobile phone middle frame, the production line is shortened, the problem that the touch screen is displaced before the hot melt adhesive is completely solidified due to the long conveying line and the multiple operation and operation is avoided, the personnel can be simplified through the process integration, the labor cost is saved, and the automatic alignment and compression can be realized through the controller, and the automation level of the production line is improved.
