[0002] A touch screen, 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 tactile 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. In order to prevent the touch screen from shifting during the cutting process, the touch screen needs to be fixed by a fixture during the processing.

[0003] A search revealed Chinese patent CN220030400U, which discloses a cutting fixture for touchscreen processing, including a support plate with connecting blocks fixedly connected to all four sides of the support plate to meet the processing requirements of different display screen orientations. However, the existing fixture only clamps specific models of touchscreens, requiring different fixtures for other models, thus limiting its functionality. To better address these issues, promote the development of industry technology, and enhance core competitiveness, this application proposes a new structural design that differs from existing technologies. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cutting fixture for touchscreen processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A cutting fixture for touchscreen processing includes a fixed frame and a carrier plate. The fixed frame and the carrier plate are connected by a guide assembly and fixed by a pin assembly. The carrier plate has two first sliding grooves, each containing a slider. The top of the slider has a slot, and a pressure block is movably connected within the slot. Two positioning posts are fixedly connected to the bottom of the pressure block. The bottom of the slider has a second sliding groove communicating with the slot, and the positioning posts slide along the second sliding groove. Springs are sleeved on the outer sides of the two positioning posts, and the two ends of the springs are fixed to the pressure block and the slider, respectively. A connecting frame is fixedly connected between the bottom ends of the two positioning posts, and a connecting shaft is fixedly connected to the bottom of the connecting frame. Two fixed plates are fixedly connected to the bottom of the carrier plate, and a bidirectional threaded rod is movably connected between the two fixed plates. Two slides are movably connected to the outer side of the bidirectional threaded rod, and each slide has a groove inside, with the connecting shaft slidably connected to the groove. The fixed plate has a power component for moving the bidirectional threaded rod.

[0006] As a further embodiment of this utility model, two guide rods are fixedly connected between the two fixed plates, and the guide rods are slidably connected to the slide.

[0007] As a further embodiment of this utility model, the guide assembly includes two slide rails, which are fixed to the bottom of the carrier plate by bolts. Guide grooves are provided on the top of both sides of the fixing frame, and the slide rails are slidably connected to the guide grooves on the carrier plate.

[0008] As a further embodiment of this utility model, the pin assembly includes multiple insertion holes, which are opened on one side of the fixing frame. A connecting plate is fixedly connected to the bottom of the carrier plate, and a lead screw is movably connected to the connecting plate, with the lead screw engaging with the corresponding insertion hole.

[0009] As a further improvement of this utility model, a clearance groove is provided at the middle position of the top of the carrier plate.

[0010] As a further embodiment of this utility model, the power component includes a motor, which is fixed to an adjacent fixing plate by bolts, and one end of the motor output shaft is fixed to a bidirectional threaded rod.

[0011] As a further improvement of this invention, a rubber pad is fixedly connected to the bottom of the pressure block.

[0018] Reference Figures 1-3 A cutting fixture for touch screen processing includes a fixed frame 5 and a carrier plate 2. The fixed frame 5 and the carrier plate 2 are connected by a guide assembly and fixed by a pin assembly. The guide assembly includes two slide rails 4, which are fixed to the bottom of the carrier plate 2 by bolts. Guide grooves are provided on the top of both sides of the fixed frame 5, and the slide rails 4 are slidably connected to the guide grooves on the carrier plate 2. The guide assembly can guide the carrier plate 2, allowing the carrier plate to move in the required direction. The pin assembly includes multiple insertion holes 6, which are provided on one side of the fixed frame 5. A connecting plate 8 is fixed to the bottom of the carrier plate 2 by bolts. A lead screw 7 is threaded onto the connecting plate 8, and the lead screw 7 is inserted into the corresponding insertion hole 6. When it is necessary to adjust the position of the carrier plate 2, the lead screw 7 is loosened, allowing the carrier plate 2 to slide along the fixed frame 5 via the slide rails 4. After the carrier plate 2 is moved to the appropriate position, the lead screw 7 is tightened and inserted into the corresponding insertion hole 6, thereby fixing the relative position of the carrier plate 2 and the fixed frame 5. This allows the operator to adjust the position of the touch screen clamped on the carrier plate 2 according to the processing requirements.

[0019] Specifically, the carrier plate 2 has two first sliding grooves 9, and a slider 10 is slidably connected in each of the two first sliding grooves 9. The top of the slider 10 has a slot 16, and a pressure block 15 is slidably connected in the slot 16. The bottom of the pressure block 15 is fixed with two positioning posts 17 by bolts. The bottom of the slider 10 has a second sliding groove 21 that communicates with the slot 16, and the positioning posts 17 are slidably connected along the second sliding groove 21. Springs 18 are sleeved on the outside of the two positioning posts 17, and the two ends of the springs 18 are fixed to the pressure block 15 and the slider 10, respectively. The bottom ends of the two positioning posts 17 are... A connecting frame 11 is bolted between the two components. A connecting shaft 20 is bolted to the bottom of the connecting frame 11. Two fixing plates 3 are bolted to the bottom of the carrier plate 2. A bidirectional threaded rod 13 is rotatably connected between the two fixing plates 3. Two slides 12 are threaded to the outer side of the bidirectional threaded rod 13. Through the cooperation of the slider 10 and the pressure block 15, the device can position and clamp touch screens of different sizes within the applicable range, making it more flexible to use and eliminating the need for repeated clamping changes. Both slides 12 have grooves 19 inside, and the connecting shaft 20 is connected to... The groove 19 is slidably connected, and the connecting shaft 20 can rotate within the groove 19. The fixed plate 3 is provided with a power component that drives the bidirectional threaded rod 13 to move. The power component includes a motor, which is a geared motor of model JGY370. The motor is fixed to an adjacent fixed plate 3 by bolts, and one end of the motor output shaft is fixed to the bidirectional threaded rod 13. The motor drives the bidirectional threaded rod 13 to rotate, thereby causing the two slides 12 to move towards each other along the bidirectional threaded rod 13. This, in turn, causes the connecting frame 11 to drive the slider 10 along the first slide groove via the connecting shaft 20. The slider 10 moves inward until it contacts the side of the touch screen. Then the slide 12 continues to move because the slider 10 is restricted by the touch screen. At this time, the connecting shaft 20 moves downward along the groove 19, which causes the connecting shaft 10 to pull the connecting bracket 11 downward. This causes the positioning column 17 to pull the pressure block 15 downward along the groove 16, and the spring 18 contracts until the bottom of the pressure block 15 contacts the upper surface of the touch screen, so that the pressure block 15 presses down on the touch screen, thereby further restricting and fixing the position of the touch screen and preventing the touch screen from shifting during the cutting process.

[0020] It should be noted that two guide rods 14 are fixed between the two fixed plates 3 by bolts, and the guide rods 14 are slidably connected to the slide 12. The guide rods 14 can guide the slide 12, so that the slide 12 can move horizontally stably and avoid the slide 12 from deviating during the movement. A clearance groove 1 is provided in the middle of the top of the carrier plate 2. The clearance groove 1 can avoid the cutting blade of the external cutting equipment. A rubber pad is glued to the bottom of the pressure block 15. The rubber pad can protect the touch screen on the carrier plate 2 and prevent the touch screen from directly contacting the pressure block 15 and easily causing wear.

[0021] Working principle: When the touch screen needs to be cut, the touch screen to be cut is first placed on the carrier plate 2, positioned between the two pressure blocks 15. Then, the motor is started, and the motor drives the bidirectional threaded rod 13 to rotate, causing the two slides 12 to move towards each other along the bidirectional threaded rod 13. This causes the connecting frame 11 to move the slider 10 along the inner side of the first slide groove 9 through the connecting shaft 20 until the slider 10 contacts the side of the touch screen. Then, the slides 12 continue to move. Because the slider 10 is restricted by the touch screen, the connecting shaft 20 moves downward along the groove 19, causing the connecting shaft 10 to pull the connecting frame 11 downward. This causes the positioning post 17 to pull the pressure block 15 downward along the groove 16, and the spring 18 contracts until the bottom of the pressure block 15 contacts the upper surface of the touch screen, pressing the touch screen down. This further restricts and fixes the position of the touch screen, preventing it from shifting during the cutting process.

[0022] When the position of the carrier plate 2 needs to be adjusted, loosen the screw 7 so that the carrier plate 2 can slide along the mounting bracket 5 via the slide rail 4. After moving the carrier plate 2 to the appropriate position, tighten the screw 7 and insert it into the corresponding socket 6 to fix the relative position of the carrier plate 2 and the mounting bracket 5, so that the operator can adjust the position of the touch screen clamped on the carrier plate 2 according to the processing requirements.
