The support plate is a rectangular frame, and the Y-axis slide rail 22 is fixed to the support plate. The dust cover 21 can cover the lead screw and the slide rails on both sides. In this embodiment, taking graphite processing as an example, the processing of graphite slices generates a lot of dust, so protective measures are necessary.

[0028] Furthermore, a fixing block is provided at the end of the support frame away from the servo motor for connecting one side of the Y-axis accordion cover 25, and the other side of the Y-axis accordion cover 25 is connected to the Y-axis slider 23. The Y-axis accordion cover 25 is located below the Y-axis lead screw 24 and can extend and retract along the Y direction as the Y-axis slider 23 moves.

The wire cutting unit includes a cutting frame 31, a driving wire wheel 371, a driven wire wheel 372, and a cutting ring wire 38. The cutting ring wire 38 is arranged around the driving wire wheel 371 and the driven wire wheel 372, and the driving wire wheel 371 and the driven wire wheel 372 are arranged on the cutting frame 31, and the cutting frame 31 is connected with the Z-axis slider 352. The second servo motor drives the Z-axis slider 352 to ascend and descend, thereby synchronously driving the cutting frame 31 to ascend and descend. The cutting frame 31 is provided with two wire wheel boxes 32 for accommodating the driving wire wheel 371 and the driven wire wheel 372 respectively. One side of the wire wheel box 32 is provided with an openable protective cover plate 321, which can be opened during the installation, removal and maintenance of the wire wheel, and the protective cover plate 321 is closed during the working process, thereby playing a dustproof role for the wire wheel box 32. The opposite side of the two wire wheel boxes 32 is provided with a through hole for the cutting ring wire 38 to pass through. The cutting ring wire 38 is a conventional diamond ring wire.

[0032] The plane where the cutting ring wire 38 is located has a certain angle with the horizontal plane, such as 45°, or other suitable angles. The lower side of the cutting ring wire 38 is horizontally arranged, thereby completing the horizontal feeding cutting of the workpiece 4.

[0033] Figure 4 and 5 As shown in the figure, the upper side of the base 11 is provided with a workpiece 4 support platform for supporting and fixing the workpiece 4. The workpiece 4 support platform includes a vacuum chuck support plate 5 for adsorbing the workpiece 4 placed in position. The vacuum chuck support plate 5 is a rectangular plate structure, and is provided with a plurality of through holes penetrating through the upper and lower sides. The lower side of the vacuum chuck support plate 5 is provided with a cavity for connecting a vacuum pumping device. The vacuum adsorption principle is a conventional technology.

[0034] Figure 6 As shown in the figure, the top-suspended movable plane cutting machine further includes a dust suction unit, and the dust suction unit includes at least one dust suction pipe.

The other side of the cross pipe 62 is connected with a second dust suction pipe 63 for connecting to a dust suction fan.

[0035] The working principle of the top-suspended movable plane cutting machine is as follows:

[0036] The protection door 13 is opened, the workpiece 4 is placed on the vacuum chuck support plate 5 along the Y-axis direction, and after being placed in position, the vacuum chuck is opened to generate suction force on the workpiece 4, and the workpiece 4 remains stationary during cutting. In this embodiment, as shown in Figure 3 two workpieces 4 are loaded, and the workpieces 4 are graphite plates with a certain interval. In other embodiments, other soft long workpieces 4 can also be processed. Before starting processing, the Y-axis and Z-axis mechanisms are adjusted to the appropriate position, for example, according to the thickness of the graphite slice, the height position of the wire cutting unit is adjusted. After adjustment, the driving wire wheel 371 of the wire cutting unit rotates (driven by the corresponding servo motor), the first servo motor 26 moves the Y-axis slider 23 along the Y-axis direction, the cutting ring wire 38 of the wire cutting unit starts to contact and gradually cut the workpiece 4, and finally completes the slicing.

[0037] This type of planar cutting machine, since the wire cutting unit is top-hung, the workpiece is stationary during cutting, and the wire cutting unit performs lifting and horizontal movement, so the feeding space in the length direction of the workpiece can be saved, and the cutting machine can adapt to the length of the workpiece itself, so the occupied space of the cutting machine in the length direction of the workpiece will be significantly reduced.
