Description

Display screen panel cutting device and display screen panel cutting equipment
Technical Field
The invention relates to the technical field of glass cutting, in particular to a display screen panel cutting device and display screen panel cutting equipment.
Background
Glass for architectural glass, photovoltaic glass, automotive glass, display glass, and the like is generally produced by cutting large-format glass into small-size glass as required by a disk-shaped cutter wheel.
As shown in fig. 1 to 6, the related art display screen panel cutting device includes a cutter frame 2 and a cutter wheel 3 mounted at one end of the cutter frame 2, one end of the cutter frame 2 remote from the cutter wheel 3 is provided with a bearing mounting handle 4, and the cutter wheel 3 is rotatably mounted on the cutter frame 2 through a pin 5. The tool rest 2 is arranged on the adapter sleeve 7 through a group of bearings 1, and the adapter sleeve 7 is connected with a moving part of the glass cutting machine. The cutter wheel 3 forms a predetermined cutting line on the glass when the moving member moves in a predetermined traveling direction 6. The tool holder 2 comprises a cylindrical bearing mounting shank 4 for mounting the bearing 1, the presence of which bearing 1 ensures that the tool holder 2 can rotate 360 degrees. As shown in fig. 6, the axis 8 of the bearing mounting shank 4 is at a distance from the geometric center of the cutter wheel 3, which is called the eccentric distance.
In the glass cutting process, when the moving part of the glass cutting machine moves according to the preset advancing direction 6, the cutter wheel 3 is pulled by the moving part, so that a preset cutting line can be formed on the glass, and the glass is cut.
When the travelling direction 6 of the moving part of the cutting machine is not perpendicular to the axial direction of the cutter wheel, namely, when the cutter wheel 3 is not positioned right behind the moving part, the cutter wheel 3 rotates around the axis of the bearing 1 under the action of friction force between the cutter wheel 3 and 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 reset under the action of the friction force between the cutter wheel 3 and glass in the process of cutting the glass.
In addition, since the tool rest 2 can freely rotate by 360 degrees, the angle of the tool rest 2 is not fixed at the beginning stage of cutting, the tool wheel 3 is likely not to be right behind the bearing 1 (i.e. a certain included angle is generally formed between the cutting advancing direction 6 of the beginning position of cutting and the direction of the blade part of the tool wheel 3), and the eccentric distance can enable the blade part of the tool wheel to automatically align along with the advancing direction of cutting, and the direction of the blade part of the tool wheel is consistent with the cutting advancing direction 6 after the cutting is conducted for a certain distance (i.e. the axial direction of the tool wheel 3 is perpendicular to the advancing direction). At this time, the actual cutting path of the cutter wheel 3 may be an end arc L1, thereby affecting the quality and yield of glass cutting.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. The following description of at least one exemplary embodiment is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Example 1
As shown in connection with fig. 7 to 11, the display screen panel cutting apparatus of the present embodiment includes a blade holder 1, a traction assembly 3, and a damping member 4.
The knife rest 1 is used for carrying a knife wheel 2 for cutting a display screen panel. The carriage 1 is rotatably mounted to the carriage 3 with the carriage 3 coupled to the carriage 1 for movement of the carriage 1 along a path for cutting the display screen panel. The damping member 4 is coupled to one of the traction assembly 3 and the tool holder 1 and abuts the other of the traction assembly 3 and the tool holder 1 to create a resistance against rotation of the tool holder 1 relative to the traction member 3.
In the prior art, after completing a cut, the display screen panel cutting device is separated from the display screen panel, and then the cutter holder 1 swings freely to cause the cutter wheel 2 to deviate from the position right behind the traction member 3, and when the cut is performed again, the cutter wheel 2 still undergoes a process of automatically rotating to the right behind the traction member 3 by the acting force between the cutter wheel 2 and the display screen panel, and the process can cause the cutting line to have an undesirable arc track.
In order to solve the problem that the cutting line has an undesirable arc track, the display screen panel cutting device further comprises a damping member 4, wherein the damping member 4 plays a role of preventing the cutter wheel 2 from rotating randomly around the rotation axis 20 of the cutter holder 1 relative to the traction assembly 3, and the damping member 4 can position the cutter wheel 2 behind the traction assembly 3 after the display screen panel cutting device completes one cutting and leaves the cut display screen panel. Further, when the display screen panel cutting device cuts the display screen panel, the force between the cutter wheel 2 and the display screen panel can overcome the positioning force of the damping member 4 to the cutter holder 1, so that the cutter wheel 2 can automatically fine-tune the position around the rotation axis 20 of the cutter holder 1.
The damping member 4 includes an elongated cantilever portion 41 and a mounting portion 42 connected to the cantilever portion 41, an end of the cantilever portion 41 remote from the mounting portion 42 being a free end, the mounting portion 42 being connected to one of the traction assembly 3 and the tool holder 1, the cantilever portion 41 being in abutment with the other of the traction assembly 3 and the tool holder 1.
As shown in fig. 11, in a plane parallel to the rotation axis 20 of the tool holder 1, the mounting portion 42 is provided at a distance from the tool holder 1, and the cantilever portion 41 extends from the mounting portion 42 toward the peripheral surface of the tool holder 1 in a direction away from the rotation axis 20 and abuts against the peripheral surface of the tool holder 1. That is, when the extending direction of the cantilever portion 41 is deviated from the radial direction of the tool holder 1 and the cantilever portion 41 extends directly toward the rotation axis 20 of the tool holder 1, the end surface of the free end of the cantilever portion 41 abuts against the tool holder 1, and the contact area between the cantilever portion 41 and the tool holder 1 is small, and the friction force with the tool holder 1 is also small. The cantilever portion 41 extends to the peripheral surface of the tool holder 1 in a direction offset from the rotation axis of the tool holder 1 and abuts against the tool holder 1, which is advantageous in increasing the contact area of the cantilever portion 41 with the tool holder 1.
The tool rest 1 protrudes out of the end face of one end of the traction assembly 3, the installation part 42 is installed on the end face of the traction assembly 3 through the screw 5, the first gasket 6 is arranged between the installation part 42 and the traction assembly 3, and the second gasket 7 is arranged between the nut of the screw 5 and the installation part 42.
As shown in fig. 12 to 14, the mounting portion 42 of the damping member 4 is annular, a threaded hole adapted to the screw 5 is provided on the end surface of the traction assembly 3, and the screw 5 is threaded into the threaded hole on the traction assembly 3 after passing through the mounting portion 42, thereby fixing the mounting portion 42 on the traction assembly 3.
The damping member 4 includes two cantilever portions 41 connected to both sides of the mounting portion 42, respectively, and the two cantilever portions 41 are located on both sides of the tool holder 1, respectively.
The tool holder 1 is provided with a plane parallel to the axis of rotation 20 of the tool holder 1, against which the cantilever portion 41 abuts.
As shown in fig. 11, in the present embodiment, the cantilever portion 41 is provided obliquely with respect to the plane, the free end of the cantilever portion 41 abuts against the plane, and the distance between at least a section of the cantilever portion 41 near the free end and the plane gradually decreases in the direction near the free end.
In other embodiments, at least a section of cantilever portion 41 is attached to a planar surface.
In this embodiment, the cantilever portion 41 is an elongated resilient member, and the cantilever portion 41 rails on the rotational path of the plane of the tool holder 1 to prevent rotation of the tool holder 1 relative to the traction assembly 3. When the cutter wheel 2 deviates from the right rear of the rotation axis 20 of the cutter head 1, the resistance of the display screen panel 2 to the cutter wheel 2 can enable the cutter head 1 to overcome the blocking of the cantilever part 41 and automatically adjust to the right rear of the rotation axis 20 of the cutter head 1 during the movement of the cutter wheel 2 along the display panel.
In the present embodiment, the tool holder 1 has two planes symmetrically arranged on both sides of the rotation axis 20 of the tool holder 1, and the two cantilever portions 41 of the damping member 4 abut against the two planes, respectively. The two cantilever portions 41 respectively prevent the tool holder 1 from rotating in opposite directions.
The two cantilever portions 41 of the damping member 4 are symmetrically arranged on both sides of the tool holder 1 to clamp the tool holder 1 between the two cantilever portions 41.
In some embodiments, the cantilever portion 41 and the mounting portion 42 of the damping member 4 are in communication with an elongated member, the middle portion of which is coiled in a ring shape to form the mounting portion 42.
As shown in fig. 7, the cutter holder in this embodiment includes a cutter wheel mount 11 for carrying the cutter wheel 2 and a mounting shaft 12 connected to the cutter wheel mount 11. The traction assembly 3 comprises a bearing 31, and the mounting shaft 12 is mounted on the bearing 31 such that the tool holder 1 is rotatable relative to the traction assembly 3. In some embodiments, the plane described above is formed on the cutterhead mount 12.
In some embodiments, the traction assembly 3 further comprises a bearing sleeve that fits over the bearing 31.
The cutter wheel 2 is rotatably mounted on the cutter frame 1, a rotation axis 10 of the cutter wheel 2 relative to the cutter frame 1 is perpendicular to a rotation axis 20 of the cutter frame 1 relative to the traction assembly 3, and the rotation axis 10 of the cutter wheel 2 and the rotation axis 20 of the cutter frame 1 are arranged at intervals in the moving direction of the traction assembly 3.
According to another aspect of the present invention, there is also provided a display screen panel cutting apparatus including the above display screen panel cutting device.
Example two
As shown in fig. 15 to 18, the tool holder 1 includes an annular member 13 extending in the circumferential direction of the rotation axis 20 of the tool holder 1, and the cantilever portion 41 of the damping member 4 abuts against the circumferential surface of the annular member 13. The friction between the cantilever portion 41 and the annular member 13 acts to resist rotation of the tool holder 1 relative to the traction assembly 3.
After the display screen panel cutting device completes one cut and leaves the cut display screen panel, the cantilever portion 41 can position the cutter wheel 2 behind the traction member 3. Further, when the display screen panel cutting device cuts the display screen panel, the force between the cutter wheel 2 and the display screen panel can overcome the resistance of the cantilever portion 41 and the annular member 13 of the cutter holder 1, so that the cutter wheel 2 can automatically fine-adjust the position about the rotation axis 20 of the cutter holder 1.
In some embodiments, the cantilever portion 41 extends in a tangential direction of the ring member 13 to increase the friction of the cantilever portion 41 with the ring member 13.
As shown in fig. 19 to 21, a groove 14 is provided on the peripheral surface of the ring member 13, and a cantilever portion 41 is fitted in the groove 14 to increase the contact area between the cantilever portion 41 and the ring member 13, thereby increasing the friction force between the cantilever portion 41 and the ring member 13.
As shown in fig. 15, the present embodiment is also different from the first embodiment in that the display screen panel cutting device further includes a third spacer 9 provided between the traction member 3 and the mounting portion 42 of the damping member 4.
Example III
As shown in fig. 22 and 23, the present embodiment is different from the first embodiment in that: the attachment portion 42 is connected to the tool holder 1, and the cantilever portion 41 abuts against the traction unit 3.
The mounting portion 42 is connected to the cutter wheel seat 11; the cantilever portion 41 extends obliquely to the axis of rotation 20 of the tool holder 1 towards the traction assembly 3 and abuts the traction member 3. The cantilever portion 41 includes an arcuate segment adjacent its free end that projects toward the traction assembly 3 and abuts the traction assembly 3 to increase the contact area between the cantilever portion 41 and the ring member 13 and thereby increase the friction between the cantilever portion 41 and the ring member 13.
In the present embodiment, the cantilever portion 4 is an elastic member. In the present embodiment, the cantilever portion 41 and the mounting portion 42 of the damping member 4 are integral.
Example IV
As shown in fig. 24, the present embodiment is different from the second embodiment in that the damping member 4 is a rigid member, and the cantilever portion 41 of the damping member 4 abuts against the annular member 13 to prevent the tool holder from rotating relative to the traction assembly 3 by the friction force between the cantilever portion 41 and the annular member 13.
After the display screen panel cutting device completes one cut and leaves the cut display screen panel, the cantilever portion 41 can position the cutter wheel 2 behind the traction member 3. Further, when the display screen panel cutting device cuts the display screen panel, the force between the cutter wheel 2 and the display screen panel can overcome the resistance of the cantilever portion 41 and the annular member 13 of the cutter holder 1, so that the cutter wheel 2 can automatically fine-adjust the position about the rotation axis 20 of the cutter holder 1.
Example five
As shown in fig. 25, the present embodiment is different from the fourth embodiment in that: the damping member 4 is an elongated member, and the damping member 4 has only one cantilever portion 41. The circumferential surface of the annular member 13 is planar and contacts the free ends of the strip-like members.
The foregoing is illustrative of the present invention and is not to be construed as limiting thereof, but rather, any modification, equivalent replacement, improvement or the like which comes within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
