Description

Technical Field

[0001] This utility model relates to the field of touch screen processing equipment technology, and in particular to a touch screen pressing device. Background Technology

[0002] A touchscreen, also known as a touch panel, is a sensor-type liquid crystal display device that can receive input signals from touch. When a graphic button on the screen is touched, the haptic feedback system on the screen can drive various connected devices according to a pre-programmed program. It can replace mechanical button panels and create vivid audio-visual effects through the liquid crystal display. The main function of the touchscreen controller is to receive touch information from the touch point detection device, convert it into touch point coordinates and send it to the CPU. At the same time, it can receive commands from the CPU and execute them.

[0003] Research revealed that traditional pressing devices lack efficient and precise automatic alignment mechanisms. When the touchscreen is conveyed to the pressing station, it is prone to positional deviation, resulting in uneven force on the edges during the pressing process. This can cause screen edge warping or poor adhesion, making it difficult to guarantee product yield. In addition, existing pressing devices rely heavily on manual collection and handling or simple mechanical stacking after the touchscreen is processed. This requires continuous manual collection and stacking, which is difficult to adapt to the high-efficiency collection requirements of automated production lines. Therefore, a touchscreen pressing device is provided to solve the above problems. Utility Model Content

The embodiments of this utility model will be described below based on its overall structure.

[0020] Reference Figures 1 to 5 In this embodiment of the present invention, a touch screen pressing device includes: Screen conveying and pressing mechanism 1 is used to convey the touch screen to be processed to a designated workstation for pressing. The screen center alignment mechanism 2 is provided on both sides and below the screen conveying and pressing mechanism 1. The screen center alignment mechanism 2 is used to adjust the touch screen to be processed to a suitable processing position before pressing. The automatic screen stacking mechanism 3 is disposed on the side of the screen conveying and pressing mechanism 1. The automatic screen stacking mechanism 3 is used to automatically stack the finished touch screen products for subsequent collection.

[0021] The screen conveying and pressing mechanism 1 includes an operating table 11. Four sets of first electric telescopic rods 12 are symmetrically fixedly connected to both sides of the operating table 11. The movable end of the first electric telescopic rod 12 is fixedly connected to the screen pressing fixture 13. A conveyor belt 14 is arranged on the inner side above the operating table 11. A screen support plate 15 is placed on the conveyor belt 14. The pressing part inside the screen pressing fixture 13 is adapted to the size of the touch screen. The screen support plate 15 has a placement groove adapted to the size of the touch screen on its inner side.

[0022] Using the above scheme: The conveyor belt 14 continuously operates to transport the screen support plate 15 carrying the touch screen to the center workstation of the operating table 11. When the sensor detects that it is in place, the four sets of first electric telescopic rods 12 press down synchronously to make the screen presser 13 and the placement groove of the screen support plate 15 form a closed pressing space. The presser part is precisely matched with the edge of the touch screen to ensure that the pressure is evenly distributed. After the pressing is completed, the first electric telescopic rods 12 are reset and raised, and the conveyor belt 14 continues to transport the screen support plate 15 to the next workstation.

[0023] The screen center alignment mechanism 2 includes an edge limiting ring 21 and a drive motor 22. There are two sets of edge limiting rings 21, which are symmetrically fixedly connected to both sides of the operating table 11. The edge limiting rings 21 are fixedly connected to the bottom of the operating table 11. The rotating shaft 34 of the drive motor 22 is fixedly connected to a rotating disk 23. Two sets of L-shaped rotating arms 24 are symmetrically rotatably connected to the bottom of the rotating disk 23. An arc-shaped clamping arm 25 is fixedly connected to the connecting column above each set of L-shaped rotating arms 24. The connecting plate part of the arc-shaped clamping arm 25 is adapted to the inner opening of the edge limiting ring 21. The connecting plate part of the arc-shaped clamping arm 25 is slidably connected to the inner side of the edge limiting ring 21. The clamping arm part of the arc-shaped clamping arm 25 is adapted to both sides of the screen support plate 15. The arc-shaped part of the arc-shaped clamping arm 25 can guide both sides of the screen support plate 15 so that it is clamped and aligned to a precise processing position by the two sets of arc-shaped clamping arms 25.

[0024] Using the above scheme: when the drive motor 22 drives the rotating disk 23 to rotate, the rotational motion is converted into linear sliding of the arc-shaped clamping arm 25 through the lever action of the L-shaped rotating arm 24. The two sets of arc-shaped clamping arms 25 move towards each other along the guide hole of the edge limiting ring 21. After their arc-shaped clamping surfaces contact the side of the screen support plate 15, they generate a centripetal thrust. The sliding limiting function of the edge limiting ring 21 is used to ensure that the clamping trajectory is accurate, and finally the central axis of the screen support plate 15 is completely coincident with the pressing center of the upper screen pressure plate 13.

[0025] The automatic screen stacking mechanism 3 includes an outer shell 31. Two sets of second electric telescopic rods 32 are fixedly connected to the inner bottom wall of the outer shell 31. A pallet guide pusher 33 is fixedly connected to the movable end of each second electric telescopic rod 32. The pallet guide pusher 33 has a ramp near the conveyor belt 14. The highest point of the ramp is close to the discharge end of the conveyor belt 14 and its height matches that of the conveyor belt 14. The horizontal portion of the side of the pallet guide pusher 33 is sized to match that of the conveyor belt 14, facilitating the sliding of the screen support plate 15 into a precise stacking position. Multiple sets of rotating shafts 34 are equidistantly rotatably connected to the inner side of the outer shell 31. Two sets of trapezoidal rotating blocks 35 are fixedly connected to the outer side of each set of rotating shafts 34. Each set of trapezoidal rotating blocks... A limiting rod 36 is fixedly connected above block 35. The limiting rod 36 is used to restrict the rotation of trapezoidal rotating block 35. Only when the pallet guide pusher 33 lifts the conveyor belt 14 and moves the conveyor belt 14 vertically upward, the two sides of the conveyor belt 14 push the long side of the trapezoidal rotating block 35 to rotate upward. After the conveyor belt 14 passes the trapezoidal rotating block 35 at the corresponding position, the long side of the trapezoidal rotating block 35 automatically resets due to gravity. When the second electric telescopic rod 32 resets, the limiting rod 36 restricts the rotation of the trapezoidal rotating block 35, and the long side lifts the two sides of the conveyor belt 14. Two sets of top columns are fixedly connected above the screen support plate 15. The height of the screen support plate 15 and the top columns are adapted to the distance between the two adjacent sets of rotating shafts 34.

[0026] The above scheme is adopted: the conveyor belt 14, together with the ramp structure of the pallet guide pusher 33, guides the screen support plate 15 to slide into the housing 31. Then, the second electric telescopic rod 32 is activated to push the pallet guide pusher 33 upward. When the pallet guide pusher 33 contacts the bottom rotating shaft 34, the long side of the trapezoidal rotating block 35 on both sides of the screen support plate 15 is squeezed, causing it to rotate upward around the rotating shaft 34. After the screen support plate 15 has completely passed the current layer's rotating shaft 34, the trapezoidal rotating block 35 is reset under the action of gravity. At this time, the limit rod 36 blocks the short side from rotating, forming a check structure. When stacking, the top column of the screen support plate 15 abuts against the bottom of the upper screen support plate 15, which facilitates the upward pushing of each layer. Through the cooperation of multiple sets of equidistant rotating shafts 34 and top columns, precise spacing between layers is achieved, and automatic vertical stacking is completed.

[0027] The working principle of this utility model is as follows: The conveyor belt 14 continuously rotates to transport the screen support plate 15 carrying the touch screen to be processed to the center station of the operating table 11. At this time, the drive motor 22 of the screen center alignment mechanism 2 starts, driving the rotating disk 23 to rotate. Through the L-shaped rotating arm 24, the two sets of arc-shaped clamping arms 25 slide towards each other along the guide hole of the edge limiting ring 21. The clamping arm part of the arc-shaped clamping arm 25 contacts both sides of the screen support plate 15 and applies a centripetal thrust to make it accurately aligned to the center axis of the processing station. After the screen support plate 15 is aligned, the four sets of first electric telescopic rods 12 press down synchronously, causing the upper screen presser 13 to close with the placement groove of the screen support plate 15. The presser part evenly presses the edge of the touch screen. After the pressing is completed, the first electric telescopic rods 12 reset and rise. The conveyor belt 14 continues to transport the screen support plate 15 carrying the finished touch screen to the ramp of the tray guide pusher 33 of the automatic screen stacking mechanism 3. The screen support plate 15 slides into the outer shell 31 along the ramp. The second electric telescopic rod 32 is activated and pushes the pallet guide pusher 33 vertically upward. The screen support plate 15 presses against the long side of the trapezoidal rotating block 35 on the bottom rotating shaft 34 on both sides, causing it to rotate upward around the rotating shaft 34. After the screen support plate 15 has completely passed the current layer rotating shaft 34, the trapezoidal rotating block 35 automatically resets due to gravity. The limit rod 36 restricts its reverse rotation to form a check structure. At this time, the top column of the screen support plate 15 abuts against the bottom of the upper screen support plate 15, which facilitates their upward pushing of each other. When the second electric telescopic rod 32 retracts, the pallet guide pusher 33 descends to the initial position, and the screen support plate 15 is lifted by the long side of the trapezoidal rotating block 35 and completed stacking. The above process is repeated. The vertical automatic stacking of the finished touch screen is achieved through the cooperation of multiple sets of equidistant rotating shafts 34 and top columns.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
