Description

Technical Field

[0001] The invention protects a cutting machine, in particular a straight surface and curved surface screen cutting machine, belonging to the technical field of mobile phone repair equipment. Background Art

[0002] With the development of electronic products such as mobile phones and tablets, their applications in people's lives are becoming more and more extensive. At present, the screen-to-body ratio of mobile phones, tablets, etc. is getting larger and larger, and even full-screen products have appeared. During the use of such electronic products, it is easy for the screen protective glass to be damaged due to squeezing, accidental falling or other reasons, so it needs to be replaced or repaired. The cover plate and the middle frame of the mobile phone screen are fixed with glue. During after-sales repair, in order to disassemble the screen and cover plate, the screen protective glass is often disassembled by heating and prying with tools, which is easy to damage the LCD screen. In order to solve this problem, people invented a screen cutter. When disassembling the screen protective glass, the screen cutter is used to cut the screen protective glass to facilitate its removal.

[0003] The plane working platform of the screen cutting machine in the prior art is fixed on the bottom plate, and the inclined working platform can be rotated to adjust its tilt angle. When it is placed horizontally, it can be used to cut straight screens (or flat screens), and when it is tilted, it can be used to cut curved screens. The purpose of the inclined working platform being able to rotate and adjust the angle is that when cutting straight screens, it can be adjusted to a plane and connected to the plane working platform to form an integrated platform. The inclined working platform is set on the right side of the plane working platform. Because the plane working platform is fixed, the operating space is too small when cutting curved screens, making it difficult to operate.

[0004] The left, right, up and down sliding of the cutting head are positioned and limited by chrome-plated rods and linear bearings, which causes the left and right, up and down swing errors of the cutting head to reach 1-2 mm. The cutting accuracy is extremely poor and the screen can be easily damaged. Summary of the invention

The plane worktable 3 is directly or indirectly mounted on the base plate 1 through a first guide rail slider pair, the inclined plane worktable 4 is mounted on the base plate 1, the horizontal adjustment mechanism is mounted on the base plate 1 through a second guide rail slider pair, the inclined plane worktable 4 is arranged between the plane worktable 3 and the horizontal adjustment mechanism, the vertical adjustment structure is mounted on the horizontal adjustment mechanism through a third guide rail slider pair, the motor 29 is mounted on the vertical adjustment structure through a fourth guide rail slider pair, and the cutting blade 30 is mounted on the main shaft of the motor 29.

[0023] In this embodiment, a plane workbench support seat 2 is fixedly installed on the bottom plate 1, a first guide rail 9 is fixedly installed above the plane workbench support seat 2, a first slider 10 is installed on the first guide rail 9, and the first slider 10 is fixedly installed together with the plane workbench 3. In this embodiment, the first slider 10 is installed at the bottom of the plane workbench 3, and the first slider 10 and the first guide rail 9 form a first guide rail slider pair, so that the first slider 10 can drive the plane workbench 3 to slide left and right along the first guide rail 9. In this embodiment, positioning strips are fixedly installed at two mutually perpendicular side edges above the plane workbench 3, which are the first positioning strip 5 and the second positioning strip 6, respectively, for positioning the mobile phone through the two edges during work. In this embodiment, on the plane The top of the plane workbench support seat 2 is fixedly installed with a first fixed magnet 15 and a second fixed magnet 16. The first fixed magnet 15 and the second fixed magnet 16 are respectively arranged corresponding to the two ends of the first guide rail 9, and can lock the plane workbench 3 to keep its position fixed. When the plane workbench 3 slides to one end of the first guide rail 9, the first fixed magnet 15 adsorbs the first slider 10 to maintain it fixed with the plane workbench 3. At this time, the inclined workbench 4 is exposed for cutting the curved screen. When the plane workbench 3 slides to the other end of the first guide rail 9, the second fixed magnet 16 adsorbs the first slider 10 to maintain it fixed with the plane workbench 3. At this time, the plane workbench 3 is located below the cutting blade 30 for cutting the flat screen. In this embodiment, a first limiting screw 12 is fixedly installed on the side of the two ends of the first guide rail 9, which can limit the first slider 10 on the first guide rail 9 to prevent the first slider 10 from escaping from the first guide rail 9 with the plane workbench 3. In this embodiment, the first limiting screw 12 is fixedly installed on the plane workbench support seat 2. In specific implementation, the first guide rail 9 can also be raised and fixed directly on the base plate 1, so that the planar workbench support seat 2 is not required.
