DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] The following further elaborates on the present utility model in conjunction with the accompanying drawings.
[0018] Combined with the atta Figures 1-4, A cutting device for a display screen, including a support base 1. At the top of the support base 1, there are multiple driving rollers 2 driven electrically, and the multiple driving rollers 2 can convey the display screen raw materials. On both sides of the support base 1, there are connected support frames 3. At the top of the support frames 3, there is an electrically driven guide rail 4 connected. At the bottom of the electrically driven guide rail 4, there is a moving slider 5 driven electrically. At the bottom of the moving slider 5, there is an electric push rod 6 connected. At the telescopic power end of the bottom of the electric push rod 6, there is a support plate 7 connected. At the bottom of the support plate 7, there is a laser cutter 8 connected. This is a common laser cutting structure for display screens. By driving the lateral movement of the moving slider 5 through the electrically driven guide rail 4, and by the electric push rod 6, the lifting operation of the support plate 7 can be driven. With the laser cutter 8 that can only move horizontally and vertically, laser cutting operations can be carried out. At the top of the support plate 7, there is a first limit sleeve rod 9 connected. At the bottom of the moving slider 5, there is a limit sleeve 21 sleeved on the first limit sleeve rod 9. By cooperating the first limit sleeve rod 9 with the limit sleeve 21, the stable lifting operation of the support plate 7 can be ensured.
[0019] On both sides of the electrically driven guide rail 4, there are connected support side plates 10. At the top of the support side plates 10, there is an electric cylinder 11 connected. At the telescopic power end of the bottom of the electric cylinder 11, there is a lifting lower pressing plate 12 connected. At the bottom of the lifting lower pressing plate 12, there is a shrinking lower pressing plate 15 connected. Inside the lifting lower pressing plate 12, there is a limit groove 18. The shrinking lower pressing plate 15 extends into the limit groove 18 and is limited and slidably provided with a limit lifting plate 17. At the top of the limit lifting plate 17, there are multiple springs 20 connected. At the inner top of the lifting lower pressing plate 12, there is a pressure sensor 19 connected. Before laser cutting, by the electric cylinder 11, the lifting lower pressing plate 12 and the shrinking lower pressing plate 15 can be driven to press down and stabilize the glass raw material. Through the multiple springs 20 and the pressure sensor 19 arranged inside, the corresponding pressure can be sensed, thereby preventing the glass from being damaged due to excessive pressure, and thus ensuring that the glass generates displacement operations during the cutting process.
[0020] At the bottom of the shrinking lower pressing plate 15, there is a rubber protection pad 16 connected. During the pressing down process, if the hard plate is directly used to press down, it is easy to cause damage and wear. Through the rubber protection pad 16, the protection operation of the glass raw material can be carried out. On both sides of the support side plates 10, there are connected limit sleeve plates 13. At the top of the lifting lower pressing plate 12, there is a second limit sleeve rod 14 penetrating the limit sleeve plates 13. By cooperating the limit sleeve plates 13 with the second limit sleeve rod 14, the stable lifting operation of the lifting lower pressing plate 12 can be ensured.
[0021] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. In general, if those of ordinary skill in the art are inspired by it and without departing from the gist of the creation of the present utility model, they design without creative efforts structural modes and embodiments similar to the technical solution, all of which shall fall within the protection scope of the present utility model.
