Description

Glass cutting device and glass cutting machine

Technical Field

The invention relates to the technical field of glass cutting, in particular to a glass cutting device and a glass cutting machine.

Background

The display panel glass of intelligent display terminals such as smart phones, tablets, computers and the like is usually cut by a disc-shaped micro-tooth diamond cutter wheel.

As shown in fig. 1 to 6, the cutter wheel 3 is rotatably mounted on the cutter holder 2 via a pin 5. The blade carrier 2 is mounted on the moving part of the glass cutting machine by a set of bearings 1, and the blade wheel 3 forms a predetermined cutting line on the glass when the moving part moves in a predetermined traveling direction 6. The tool post 2 comprises a cylindrical bearing mounting handle 4 for mounting the bearing 1, the bearing 1 is mounted on a moving part of the cutting machine, the bearing 1 can ensure that the tool post 2 can rotate 360 degrees, and the distance between the center of the bearing mounting handle 4 and a parallel line passing through the geometric center of the cutter wheel 3 is L, which is called an eccentric distance L.

The axial direction of the bearing 1 is vertical to the advancing direction 6 of the moving part of the cutting machine, the axial direction of the cutter wheel 3 is vertical to the axial direction of the bearing 1, and when the cutter wheel 3 is positioned right behind the bearing 1, the axial line of the cutter wheel 3 is vertical to the advancing direction 6 of the moving part.

When cutting glass, the cutting machine draws the tool rest 2 and the tool wheel 3 to move along the required cutting direction through the moving parts. When the advancing direction 6 of the moving part of the cutting machine is not perpendicular to the axial direction of the cutter wheel, namely the cutter wheel 3 is not positioned right behind the moving part, the cutter wheel rotates around the axis of the bearing 1 under the action of the friction force between the cutter wheel 3 and the glass, so that the cutter wheel 3 rotates right behind the axis of the bearing 1, and therefore, the cutter wheel 3 can be automatically aligned under the action of the friction force between the cutter wheel 3 and the glass in the process of cutting the glass.

In addition, since the knife rest 2 can freely rotate in 360 degrees, the angle of the knife rest 2 is not fixed in the initial stage of cutting, the knife flywheel 3 is likely not to be right behind the bearing 1 (that is, there is a certain included angle between the cutting advancing direction 6 of the initial cutting position and the direction of the edge of the knife flywheel 3 in general), and the existence of the eccentric distance L can enable the edge of the knife flywheel to be automatically aligned along with the advancing of the cutting, and the direction of the edge of the knife flywheel after the cutting is performed for a certain distance L1 is consistent with the cutting advancing direction 6 (that is, the axial direction of the knife flywheel 3 is perpendicular to the advancing direction). At this time, the actual cutting path of the cutter wheel 3 will be an arc L2, as shown in fig. 6, and the arc L2 is typically about 0.5-10mm in size.

At present, the design of a display panel enables the cutting position to be outside the use area of the panel every time, namely, the initial cutting arc line L2 is outside the use area, but some panel designs require that the cutting initial position is the boundary of the use area, or the cutting initial position is very close to the use area, the existence of the arc line L2 can seriously affect the qualified rate of cutting, and the problem that the direction of a cutter wheel at the cutting initial position is inconsistent with the cutting direction is solved to become a key of the cutter rest design.
