Description

Technical Field

[0001] This utility model relates to the technical field of touch screen pressing, specifically a pressing device for touch screen processing. Background Technology

[0002] A touchscreen is also known as a sensor-based liquid crystal display device that can receive input signals from touch. Touchscreen lamination is a process used in touchscreen manufacturing to tightly bond the two main components of the touchscreen together.

[0003] According to Chinese Patent No. CN221969155U, a precision pressing device for touchscreen processing is disclosed, including a base plate, a pressing component on the top of the base plate, and a stabilizing component that works in conjunction with the pressing component. The stabilizing component includes several fixing rods fixedly installed on the side of the base plate. One side of each fixing rod is provided with a movably connected carrier plate, the top of each fixing rod is provided with a movably connected support rod, and the outer side of each support rod is provided with a movably connected stabilizing plate. This precision pressing device for touchscreen processing works by placing the touchscreen to be pressed on top of the carrier plate, sliding the carrier plate into a sliding groove, rotating the support rod, causing the top plate to move downwards within the fixing rod, and simultaneously activating a hydraulic rod. The extension of the hydraulic rod causes the lower cylindrical fixing seat to descend, and the descent of the fixing seat causes the stabilizing plate to slide outside the support rod, simultaneously pushing the fixing plate downwards. The descent of the fixing plate causes the pressing plate to precisely press the touchscreen on the carrier plate.

[0004] The above solution still has the following shortcomings: during the touch screen processing and pressing process, the pressing component may cause uneven force on the touch screen after contact with the touch screen, resulting in more bulges on the touch screen and thus affecting the product quality of the touch screen. Utility Model Content

[0005] The purpose of this invention is to provide a pressing device for touch screen processing, in order to solve the problem that during the pressing process of touch screen processing, the pressing component may cause uneven force on the touch screen after contact with the touch screen, resulting in more bulges on the touch screen and thus affecting the product quality of the touch screen.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a pressing device for touch screen processing, comprising a base, a U-shaped frame fixed on the front and rear sides of the base, a slide table on the left and right sides of the crossbar of the U-shaped frame, a slider slidably disposed between the two slide tables, a first electric push rod fixed at the bottom of the slider, an installation rod fixed at the output end of the first electric push rod, and a pressure roller rotatably disposed between the installation rods.

[0007] Preferably, the top surface of the base is provided with a placement groove, the bottom surface of the placement groove is fixed with a pressure sensor, and the pressure roller is directly above one end of the placement groove.

[0008] Preferably, two second electric push rods are respectively provided on the left and right sides inside the placement slot, and the output ends of the two second electric push rods are fixed with fixing plates.

[0009] Preferably, the top surface of the fixing plate is provided with a sliding groove, and an L-shaped limiting plate is slidably disposed inside the sliding groove.

[0010] Preferably, a sponge pad is provided at one end of the fixing plate.

[0011] Preferably, a PLC controller is fixed on the left side of the base, and the slide, the first electric push rod, the pressure sensor, the second electric push rod are electrically connected to the PLC controller.

[0012] Compared with the prior art, the pressing device for touch screen processing that adopts the above technical solution has the following beneficial effects:

[0013] 1. The operator places the touchscreen at one end of the placement slot, with that end directly below the pressure roller. The PLC controller then activates the first electric push rod. Since the pressure roller is fixed to the output end of the first electric push rod, it moves downwards under the push rod's influence. When the pressure roller contacts the top surface of the touchscreen, it applies downward pressure. Because a pressure sensor is fixed to the bottom of the placement slot, the pressure sensed by the touchscreen is received and transmitted to the PLC controller, preventing excessive pressure from crushing the touchscreen. When the appropriate pressure is reached, the first electric push rod is stopped, and the two sliding tables are activated. Since the sliding tables and sliders are slidably connected, the sliders move, driving the first electric push rod. The movement of the first push rod causes the pressure roller to rotate, thus pressing the two components of the touchscreen together. The rolling pressure roller effectively presses the two components of the touchscreen together, and during the movement, it squeezes out any air bubbles generated during the pressing process, preventing bubble formation. Furthermore, the force between the pressure roller and the touchscreen is even, improving the product quality of the touchscreen.

[0014] 2. After the operator places the touchscreen into one end of the placement slot, the PLC controller activates four second electric push rods. Since each pair of second electric push rods has a fixed plate at its output end, the push rods stop after a brief contact between the two fixed plates and the sides of the touchscreen. The fixed plates then completely secure the touchscreen, preventing it from shaking during the pressing process. Furthermore, the fixed plate has a sponge pad at the contact end with the touchscreen, preventing excessive pressure from damaging the ends of the touchscreen. After securing it, the L-shaped limiting plate is adjusted so that one end of the L-shaped limiting plate contacts both sides of the touchscreen, and the plate at this contact end is thin enough that excessive pressure at one end during the pressing process causes the sides and rear end to lift, improving the bonding quality of the touchscreen.

[0020] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1-4 As shown, a pressing device for touch screen processing includes a base 1. U-shaped frames 2 are fixed to the front and rear sides of the base 1. Slide tables 3 are respectively arranged on the left and right sides of the crossbar of the U-shaped frames 2. A slider 4 is slidably arranged between the two slide tables 3. A first electric push rod 5 is fixed to the bottom of the slider 4. A mounting rod 6 is fixed to the output end of the first electric push rod 5. A pressure roller 7 is rotatably arranged between the mounting rods 6. A placement groove 8 is formed on the top surface of the base 1. A pressure sensor 9 is fixed to the bottom surface of the placement groove 8. The pressure roller 7 corresponds to the top of one end of the placement groove 8.

[0022] In use, the operator places the touchscreen at one end of the placement groove 8, with that end directly below the pressure roller 7. Then, the PLC controller 15 activates the first electric push rod 5. Since the pressure roller 7 is fixed to the output end of the first electric push rod 5, it moves downwards under the influence of the first electric push rod 5. When the pressure roller 7 contacts the top surface of the touchscreen, it generates downward pressure. Because a pressure sensor 9 is fixed to the bottom surface of the placement groove 8, the pressure sensed by the touchscreen is received by the pressure sensor 9 and transmitted to the PLC controller 15, thus preventing excessive pressure from crushing the touchscreen. When the appropriate pressure is reached, the first electric push rod 5 is stopped, and then the two slides 3 are activated. Since the slides 3 and the slider 4 are slidably connected, the slider 4 moves, causing the first electric push rod 5 to move. The movement of the first electric push rod 5 causes the pressure roller 7 to rotate, thereby pressing the two parts of the touchscreen together. The roller 7 can press the two parts of the touch screen together, and during the movement, it can squeeze out the air bubbles generated during the pressing process, so that no air bubbles are generated. In addition, the force between the roller 7 and the touch screen is uniform, thereby improving the product quality of the touch screen.

[0023] like Figures 2-4 As shown, two second electric push rods 10 are respectively arranged on the left and right sides inside the placement slot 8, and the output ends of the two second electric push rods 10 are fixed with fixing plates 11. A sliding groove 12 is opened on the top surface of the fixing plate 11, and an L-shaped limiting plate 13 is slidably arranged inside the sliding groove 12. A sponge pad 14 is provided at one end of the fixing plate 11. A PLC controller 15 is fixed on the left side of the base 1. The PLC controller 15 is a Siemens 6ES7511-1AK02-0AB0. The slide table 3, the first electric push rod 5, the pressure sensor 9, and the second electric push rods 10 are electrically connected to the PLC controller 15.

[0024] During use, the operator places the touchscreen into one end of the placement slot 8, and then activates four second electric push rods 10 via the PLC controller 15. Since each pair of second electric push rods 10 has a fixing plate 11 at its output end, after the two fixing plates 11 briefly contact the sides of the touchscreen, the four second electric push rods 10 are stopped. Under the action of the two fixing plates 11, the touchscreen is completely fixed, preventing it from shaking during the pressing process. Furthermore, since a sponge pad 14 is fixed to the end of the fixing plate 11 that contacts the touchscreen, excessive pressure from the fixing plate 11 prevents damage to the ends of the touchscreen. After fixing, the L-shaped limiting plate 13 is adjusted so that one end of the L-shaped limiting plate 13 contacts the sides of the touchscreen, and the height of this contacting end is sufficiently thin. During the touchscreen pressing process, excessive pressure at one end causes the sides and rear end to lift, improving the adhesion quality of the touchscreen.

[0025] 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.
