The tool rest according to the embodiment of the present invention will be described in detail below based on fig. 1A to 4.

Fig. 1A schematically illustrates one of perspective views of a tool holder according to an embodiment of the present invention, fig. 2A schematically illustrates one of perspective views of a tool holder mount and a second position adjustment portion according to an embodiment of the present invention, and fig. 3A schematically illustrates one of perspective views of a first position adjustment portion according to an embodiment of the present invention.

Referring to fig. 1A, 2A and 3A in combination, an embodiment of the present invention provides a tool holder for mounting a tool D, wherein the tool D may refer to a tool D for cutting a display panel including, but not limited to, a liquid crystal panel, for example, the display panel may further include an organic electroluminescent display panel. The cutter holder may carry the cutter D to perform a displacement so as to cut in a predetermined direction at a designated position on the display panel, and further perform operations such as rough cutting or fine cutting to cut off an unnecessary portion on the display panel.

Referring to fig. 1A, a tool holder includes: a tool holder mount 100 and a first position adjustment portion 200. The tool rest mounting seat 100 is a base of the whole tool rest, the tool rest mounting seat 100 is used as a connecting medium between the tool rest and an external mechanism, and detachable mounting between the tool rest and the external mechanism can be realized, for example, the tool rest mounting seat 100 can be fixedly connected with a moving assembly on a wire motor machine. The first position adjusting portion 200 is disposed on the tool rest mount 100, and optionally, the first position adjusting portion 200 may be fixedly connected to the tool rest mount 100 or may be movably connected to the tool rest mount 100, which will be described in detail below and not be repeated herein.

Referring to fig. 1A and 2A in combination, the first position adjusting part 200 includes: a first mounting assembly 210, a first drive assembly 220, a first cutter mounting assembly 230, and a second cutter mounting assembly 240. The first mounting assembly 210 is used to achieve the connection between the first position adjusting portion 200 and the tool rest mount 100, and when the first position adjusting portion 200 is movably connected to the tool rest mount 100, the first mounting assembly 210 may be connected to the tool rest mount 100 through the second position adjusting portion 300, and further, the second position adjusting portion 300 may drive the entire first position adjusting portion 200 to displace in the second direction X relative to the tool rest mount 100, where the second direction X intersects the first direction Z, for example, where the second direction X is perpendicular to the first direction Z.

The first mounting assembly 210 includes a first base 211 and a first mounting plate 212, the first base 211 being coupled to the tool holder mount 100, at least one side of the first mounting plate 212 being coupled to the first base 211. For example, referring to fig. 2A, the first base 211 includes two risers extending in the first direction Z, and adjacent two sides of the first mounting plate 212 are respectively connected to inner sides of the two risers.

The first tool mounting assembly 230 and the second tool mounting assembly 240 are used to mount tools D, respectively, and the tools D mounted on the first tool mounting assembly 230 and the second tool mounting assembly 240 may be the same or different, and are specifically determined according to actual needs, and are not limited herein.

The first drive assembly 220 is used to drive the first and second tool mount assemblies 230, 240 for finer movement in the first direction Z. Illustratively, the first direction Z is in the same direction as the thickness direction of the display panel to be cut, so that the spacing between the first and second cutter mounting assemblies 230 and 240 and the display panel, and thus the cutting pressure or depth of the cutter D on the display panel, can be precisely controlled by the first driving assembly 220. In addition, the first drive assembly 220 may also be used for quick tool change, for example, by the first drive assembly 220, the first tool mounting assembly 230 (or the second tool mounting assembly 240) with the target tool D mounted thereto may be driven to an operative position, leaving the second tool mounting assembly 240 (or the first tool mounting assembly 230) without the target tool D mounted thereto away from the operative position, without requiring a shutdown in the process. Compared with the scheme that the cutter D is required to be disassembled by stopping in the traditional scheme to complete the cutter changing, the embodiment of the invention remarkably improves the cutter changing efficiency.

Specifically, the first driving assembly 220 includes: the first rotating wheel 221 and the first servo motor 222 driving the first rotating wheel 221 to rotate, wherein the first servo motor 222 is installed on the first installation plate 212, the axial direction of the first rotating wheel 221 is in the same direction with the thickness direction of the first installation plate 212, the first installation plate 212 and the first rotating wheel 221 are arranged along a first direction Z, and the first direction Z is in the same direction with the axial direction of the first rotating wheel 221.

Referring to fig. 2A, the first servomotor 222 and the first rotary wheel 221 are located on different sides of the first mounting plate 212, for example, the first mounting plate 212 includes two sides disposed opposite in the first direction Z, wherein one side may be the upper side of the first mounting plate 212 in fig. 2A, and the other side may be the lower side of the first mounting plate 212 in fig. 2A. The first servo motor 222 is located at an upper side of the first mounting plate 212, and the first rotating wheel 221 is located at a lower side of the first mounting plate 212, that is, the first servo motor 222, the first mounting plate 212, and the first rotating wheel 221 are sequentially arranged in the vertical direction in fig. 2A. Alternatively, the rotation shaft of the first servomotor 222 extends in the first direction Z, and the rotation shaft of the first servomotor 222 is connected to the first rotation wheel 221 after passing through the first mounting plate 212.

The first tool mounting assembly 230 includes: a first cutter mounting end 231 and a first cutter mounting opposite end 232 disposed opposite in a first direction Z, the second cutter mounting assembly 240 comprising: a second tool mounting end 241 and a second tool mounting opposite end 242 disposed opposite in the first direction Z. For example, the first tool mounting end 231 and the first tool mounting opposite end 232 are disposed opposite in the vertical direction in fig. 2A, wherein the first tool mounting end 231 is located below the first tool mounting opposite end 232 in fig. 2A. The second tool mounting end 241 and the second tool mounting counter end 242 are disposed opposite in the vertical direction in fig. 2A, wherein the second tool mounting end 241 is located below the second tool mounting counter end 242 in fig. 2A. The first tool mounting end 231 and the second tool mounting end 241 are for mounting a tool D.

Alternatively, the first and second tool mounting assemblies 230, 240 may be aligned along a third direction Y, which intersects with each other, e.g., the third direction Y, the second direction X, and the first direction Z are perpendicular to each other. Wherein the first and second tool mounting assemblies 230, 240 may be substantially mirror images, the mirror surface may pass through a midpoint of the first wheel 221 and be parallel to a plane defined by the first and second directions Z, X. In some drawings of the embodiment of the present invention, a part of the second tool mounting assembly 240 is blocked by a structure such as a protective shield DB, and the specific structure of this part may refer to the corresponding part of the first tool mounting assembly 230, which is not described herein.

Fig. 2B schematically illustrates a front view of the first position adjusting portion according to an embodiment of the present invention.

Referring to fig. 2A and 2B in combination, a side of the first rotating wheel 221 facing away from the first mounting plate 212 includes a first curved surface Q1, and the first tool mounting opposite end 232 and the second tool mounting opposite end 242 both abut against the first curved surface Q1, and the topography of the first curved surface Q1 is configured to: the first tool mounting end 231 is made to protrude from the second tool mounting end 241 in the first direction Z when the first rotation wheel 221 is rotated to the first position, and the second tool mounting end 241 is made to protrude from the first tool mounting end 231 in the first direction Z when the first rotation wheel 221 is rotated to the second position.

For example, the first wheel 221 includes two surfaces disposed opposite to each other in the vertical direction in fig. 2B, one of which may be an upper surface of the first wheel 221 in fig. 2B, the other surface may be a lower surface of the first wheel 221 in fig. 2B, and the first curved surface Q1 may refer to the lower surface of the first wheel 221. Different regions of the first curved surface Q1 may have different curved surface heights, wherein the curved surface heights may refer to a distance between the region and the upper surface of the first rotation wheel 221. When the first rotating wheel 221 rotates, the first tool mounting end 232 and the second tool mounting end 242 can be driven to move in the first direction Z by the first curved surface Q1, and the movement directions of the two can be reversed. For example, the second tool mounting opposite end 242 may be moved upward when the first tool mounting end 231 is moved downward, and the second tool mounting opposite end 242 may be moved downward when the first tool mounting end 231 is moved upward. When the first cutter mounting end 231 moves downward to the target position, the first cutter mounting end 231 protrudes from the second cutter mounting end 241 in the first direction Z, that is, the first cutter mounting end 231 is lower than the second cutter mounting end 241, at this time, the first cutter mounting end 231 reaches the working position, and the cutter D thereon can cut the display panel.
