[0002] A touchscreen, also known as a touch panel, is a sensor-based 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. As a latest computer input device, the touchscreen is currently the simplest, most convenient, and most natural way for humans to interact with computers.

[0003] Currently, touchscreens typically require laser etching during the production process. This process involves opening the laser etching machine's processing space, placing the touchscreen glass panel on the worktable, closing the machine's cabinet door, and then using the machine's built-in controller and program to operate the laser head and etch the glass panel. However, this process requires frequent opening of the cabinet door to replace the glass panel, making it complex and inconvenient to change the processing table.

[0031] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0032] See Figure 1-11This invention provides a laser etching machine for touch screen production, comprising a cabinet 3 and a controller 1. The controller 1 is located on the top of the cabinet 3. A laser head 8 is connected to the top of the cabinet 3 and is connected to the controller 1 via a wire. The controller 1 controls the operation of the laser head 8. Both sides of the cabinet 3 have inlet and outlet ports 31 for the touch screen to enter and exit. An electric cylinder 6 and a processing table 7 are provided inside the cabinet 3. The telescopic rod at the top of the electric cylinder 6 is fixedly connected to a support frame 12. The support frame 12 is located on the lower side of the processing table 7 and the processing table 7 slides along the support frame 12. A left limit frame 9 and a right limit frame 10 are provided on the processing table 7, and both the left limit frame 9 and the right limit frame 10 are rotatably connected to the processing table 7.

[0033] A rack plate 17 is inlaid and fixed in the middle of the lower side of the processing table 7. A circular gear 122 is meshed and connected to the lower side of the rack plate 17. The circular gear 122 is rotatably connected to the support frame 12 through a connecting rod. Two positioning seats 72 are symmetrically welded and fixed to the upper side of the processing table 7. The positioning seats 72 are rotatably connected to the left limit frame 9 and the right limit frame 10 through a rotating shaft. A baffle 11 is integrally connected to the lower side of the left limit frame 9 and the right limit frame 10. The baffle 11 is located on the left and right sides of the processing table 7 and the circular gear 122, and the lower side of the baffle 11 is on the same horizontal plane as the bottom surface of the support frame 12.

[0034] In the process of using this invention, a stepper motor is first fixed to the back of the support frame 12 and connected to the rotating rod 18. Simultaneously, the controller 1 controls the operation of both the stepper motor and the electric cylinder 6. The program for etching the desired shape is built into the controller 1. When laser etching is required on the touchscreen glass plate, the electric cylinder 6 moves the processing table 7 to a position level with the inlet / outlet ports 31 on both sides. Then, the stepper motor drives the connecting rod to rotate, which in turn drives the circular gear 122 to rotate. Under the action of the gear teeth, the rack plate 17 moves to the right, simultaneously moving the processing table 7 to the right along the limiting slider 13 and the support frame 12. Then, the right side of the processing table 7 passes through the inlet / outlet port 31, and when the baffle 11 on the left limiting frame 9 contacts the left side of the support frame 12, the movement of the processing table 7 is limited. Then the operation begins. The operator rotates the right limiting frame 10 upwards, places the glass plate on the processing table 7, and slides it into the left limiting frame 9. Then, the right limiting frame 10 is rotated in the opposite direction. The glass plate is clamped, fixed, and limited by the left and right limiting frames 9 and 10. The processing table 7 is then reset by the stepper motor and electric cylinder 6. The laser head 8 is then operated by the controller 1 to perform laser etching on the glass plate. After the laser etching is completed, the electric cylinder 6 and stepper motor are operated again. This time, the stepper motor moves the processing table 7 to the left, thus extending the processing table 7 from the left inlet / outlet 31. The left limiting frame 9 is then rotated upwards to separate it from the glass plate. The laser-etched glass plate is then removed from the processing table 7. The processing table 7 is then moved to the right inlet / outlet 31 to process the next glass plate.

[0035] like Figure 4 , Figure 6 and Figure 7 As shown, the front and rear sides of the processing table 7 are provided with sliding grooves 71. The top of the front side of the support frame 12 is provided with a limiting slider 13. The limiting slider 13 and the rear of the support frame 12 are both located in the sliding grooves 71. The limiting slider 13 is provided with an opening groove 131. The opening groove 131 is provided with a connecting plate 132 and a positioning rod 133. The positioning rod 133 is fixedly connected to the connecting plate 132 and is inserted into the limiting slider 13. It moves up and down along the limiting slider 13. The lower part of the positioning rod 133 extends into the positioning hole 121 on the support frame 12.

[0036] In use, the cabinet door of the cabinet 3 is opened, and the connecting plate 132 is grasped and moved upward. This causes the positioning rod 133 to move upward and separate from the positioning hole 121. Then, the limiting slider 13 is moved forward to separate the limiting slider 13 from the processing table 7. The processing table 7 is then removed from the support frame 12, achieving the purpose of easy disassembly. The processing table 7 of the required specifications is then placed on the support frame 12, and the limiting slider 13 is placed into the groove 71 on the processing table 7 again. The connecting plate 132 is moved downward, and the positioning rod 133 is inserted into the positioning hole 121 again. The support frame 12 and the limiting slider 13 achieve the purpose of limiting the processing table 7, making installation convenient and the operation simple.

[0037] like Figure 4 and Figure 9 As shown, a housing 16 is fixedly connected to the left side of the left limiting frame 9 and the right side of the right limiting frame 10. A buffer spring 15 and a clamping bar 14 are provided inside the housing 16. A through hole 101 is provided inside the left limiting frame 9 and the right limiting frame 10. The clamping bar 14 is provided in the through hole 101 and moves left and right along the through hole 101. An inclined surface is provided on the lower side of the clamping bar 14.

[0038] In use, when the glass plate is slid into the left limiting frame 9, the glass plate presses against the clamping bar 14 on the left limiting frame 9, thereby moving the clamping bar 14 into the through hole 101 and compressing the buffer spring 15. Then, the right limiting frame 10 is reset, and the clamping bar 14 on the right limiting frame 10 moves to the right under the action of the inclined surface, thereby also compressing the buffer spring 15. At this time, the glass plate is stably clamped by the left limiting frame 9, the right limiting frame 10, and the clamping bar 14, which improves stability. When it is necessary to remove the glass plate, the left limiting frame 9 is rotated upward, at which time the left limiting frame 9 separates from the glass plate. Then, the buffer spring 15 on the right limiting frame 10 returns to its original deformation and moves the clamping bar 14 to the left, thereby pushing the glass plate out, making it convenient for the staff to remove the glass plate.

[0039] like Figure 1 and Figure 3 As shown, protective trays 2 are provided on both the left and right sides of the cabinet 3. The protective trays 2 are located below the inlet / outlet 31 and are rotatably connected to the cabinet 3 via hinges. The protective trays 2 facilitate the placement of glass plates. The outer side of the protective trays 2 is provided with magnetic strips 21 and notches 22. The notches 22 are located on the front and rear sides of the magnetic strips 21. The magnetic strips 21 facilitate the magnetic connection between the protective trays 2 and the side of the cabinet 3, thereby closing the inlet / outlet 31. The notches 22 facilitate the gripping of one side of the protective trays 2, thereby opening the protective trays 2.

[0040] like Figure 1 , Figures 10-14 As shown, a limiting frame 4 is fixedly connected to the bottom of the cabinet 3. A base plate 5 is slidably connected inside the limiting frame 4. The base plate 5 is fixed to the lower side of the electric cylinder 6. A positioning groove 33 is opened at the bottom of the cabinet 3. The lower part of the protruding plate 19 is set inside the positioning groove 33. The protruding plate 19 is sleeved and fixed on the rotating rod 18. The rotating rod 18 is set inside the base plate 5 and is rotatably connected to the base plate 5. A knob is connected to the front side of the rotating rod 18, and an indicator head is set on the knob. The knob is located on the front side of the base plate 5.

[0041] The base plate 5 is equipped with a semiconductor cooling chip 20 and a heat dissipation fin 23. The cold side of the semiconductor cooling chip 20 is in contact with the electric cylinder 6, and the hot side of the semiconductor cooling chip 20 is in contact with the heat dissipation fin 23. A groove 34 is provided at the bottom of the cabinet 3. A suction fan 24 is fixedly connected to the top of the groove 34, and the suction fan 24 is located on the lower side of the heat dissipation fin 23.

[0042] The base plate 5 has multiple air intake channels 51 inside, and the air intake channels 51 are symmetrically arranged on both sides of the heat dissipation fins 23 and are in contact with the space where the heat dissipation fins 23 are located. The air intake channels 51 are shaped with the upper side being larger and the lower side being smaller.

[0043] In use, the base plate 5 is slid into the limiting frame 4, and then the knob is turned to rotate the convex plate 19. The convex plate 19 then rotates into the positioning groove 33, thereby positioning the base plate 5. The semiconductor cooling chip 20 and the suction fan 24 are connected to an external power source and operated. The operation of the suction fan 24 facilitates the absorption and delivery of air inside the cabinet 3. The air inside the cabinet 3 then enters the air intake duct 51, passes through the suction fan 24, and enters the groove 3. The heat is then discharged to the outside of the cabinet 3 through the air vent 32. During the airflow, the heat emitted from the laser head 8, stepper motor, and electric cylinder 6 is carried out, achieving the purpose of heat dissipation. The airflow also dissipates heat from the heat dissipation fins 23. The heat dissipation fins 23 are then cooled and transferred to the hot surface of the thermoelectric cooler 20, and then to the cold surface of the thermoelectric cooler 20, which cools the cold surface of the thermoelectric cooler 20. In turn, the thermoelectric cooler 20 directly cools the electric cylinder 6, resulting in high heat dissipation efficiency.

[0044] like Figure 14 As shown, multiple air holes 32 are provided on the lower left and lower right sides of the cabinet 3, and the air holes 32 are connected to the grooves 34, so that the suction fan 24 can exhaust the heat generated inside the cabinet 3 to the outside of the cabinet 3 with the hot air.

[0045] The above are merely embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
