During the processing, the movement of the processing head 11 in the X-axis direction can feed the sheet under processing in the X-axis direction. The material rack 12, the workbench 14 and the machining head 11 can be sequentially arranged in the second direction, namely the material rack 12, the workbench 14 and the machining head 11 are sequentially arranged in the Y-axis direction, so that the feeding and discharging mechanical arm 2 can conveniently move the sheets between the material rack 12 and the positioning mechanism 13.

It is understood that the machining head 111 may be retracted inside the machining head 11 or may be extended outside the machining head 11, that is, the machining head 111 may be moved up and down in the Z direction to adjust the movement of the machining head 11 in the Z axis. During the processing, the processing head 111 can feed the sheet being processed in the Z-axis direction by its own expansion and contraction function.
Further, the processing apparatus 1 is connected to a linear motor (not shown in the drawings), and a linear slide rail (not shown in the drawings) can be used in cooperation with the linear motor, specifically: the workbench 14 can be connected with a first linear motor, and the workbench 14 can be slidably connected to the machine tool base 3 through a first linear sliding rail, so that the first linear motor drives the workbench 14 to slide along the first linear sliding rail; the processing aircraft nose 11 can be connected with second linear electric motor to processing aircraft nose 11 accessible second linear slide rail sliding connection is in support frame 4, and then second linear electric motor drive processing aircraft nose 11 slides along second linear slide rail.

Of course, in practical applications, the machining device 1 is not limited to the linear movement realized by the cooperation of the linear motor and the linear slide rail, and may also be realized by various mechanical structures such as a ball screw, a belt transmission, a rack and pinion transmission, and the like, that is, the movement of the worktable 14 relative to the machine tool base 3 may be realized by the above alternative, and the movement of the machining head 11 relative to the support frame 4 may also be realized by the above alternative, so that the stable movement may be realized, and the machining precision may be improved.
Optionally, a processing boss 15 may be further disposed at a position of the working table 14 corresponding to the positioning mechanism 13, so as to facilitate positioning of the sheet by the positioning mechanism 13 and processing of the sheet by the processing head 11; the processing boss 15 can be disposed on the worktable 14, and the worktable 14 drives the processing boss 15 to move when moving. In the processing process, a sheet to be processed can be placed on the processing boss 15, then the sheet is positioned through the positioning mechanism 13, the workbench 14 is controlled to move so as to drive the sheet on the processing boss 15 to move, and the sheet is processed by matching with the processing machine head 11.

Alternatively, as shown in fig. 1, each processing device 1 may be provided with at least two processing stations, and the at least two processing stations may be arranged in the first direction, that is, the at least two processing stations may be arranged in the X-axis direction. Preferably, each processing device 1 comprises two processing stations, and the two processing stations are arranged along the X-axis direction, so that each processing device 1 has two processing heads 11, and the two processing heads 11 form a group, that is, the two processing heads 11 can be simultaneously controlled to process two sheets respectively. Each processing device 1 is provided with two processing stations, so that on one hand, the full-automatic feeding and discharging intelligent CNC processing equipment can simultaneously process four sheets, and the processing efficiency is improved; on the other hand, the two processing devices 1 can independently operate, even two processing stations in each processing device 1 can independently operate, and cannot mutually influence when processing sheets, and each processing device 1 can process according to the content required to be processed by the respective sheet to be processed, so that the processing precision is improved, and the quality of the processed product is better.
Further, when each processing device 1 is provided with at least two processing stations, the working table 14 of each processing station can have two arrangements, specifically as follows:
as a first arrangement of the working table 14, as shown in fig. 3, in the present embodiment, each working table 14 in each processing device 1 is integrally formed to form a larger working table 14, and the processing bosses 15 and the positioning mechanisms 13 of all processing stations in each processing device 1 are all disposed on the working table 14, that is, during the processing, the working table 14 moves to drive all the processing bosses 15 in the whole processing device 1 and the sheets supported by the processing bosses 15 to move, which can be understood as that all the sheets on the working table 14 move synchronously. Based on this, the processing heads 11 of all processing stations in each processing device 1 are also set to move synchronously to match with the corresponding processing bosses 15; in addition, the processing heads 11 of the adjacent processing stations can be arranged without intervals, so that the space occupancy rate of the parts can be effectively reduced.
As a second arrangement of the working table 14, in a specific application, the working table 14 of each processing station in each processing device 1 is independently arranged, that is, each processing station has one working table 14 independently and is not shared with the working tables 14 of other processing stations, that is, during the processing, the working table 14 of each processing station can only move the processing boss 15 in the processing station and the sheet supported by the processing boss 15. Based on this, the processing heads 11 of the processing stations in the processing devices 1 can operate independently and only need to be matched with the processing bosses 15 of the respective processing stations; and, the processing heads 11 of the adjacent processing stations have a certain interval therebetween to avoid the interference problem that may be generated when each is operated.
Alternatively, as shown in fig. 1 and 4, the loading and unloading robot 2 includes a cross beam 23, a moving longitudinal beam 22, and a loading and unloading assembly 21. The cross beam 23 may be disposed on the top of the machine tool base 3 along the second direction, and one end of the cross beam 23 may be disposed on the support frame 4, that is, the cross beam 23 is disposed along the Y-axis direction. One end of the movable longitudinal beam 22 is movably connected to the cross beam 23 so as to enable the movable longitudinal beam 22 to move along the length direction (i.e. the Y-axis direction) of the cross beam 23, and the other end of the movable longitudinal beam 22 is movably connected to the machine tool base 3, namely, the movable longitudinal beam 22 is vertically placed on the machine tool base 3, and so as to enable the movable longitudinal beam 22 to move on the machine tool base 3 along the second direction, namely, the movable longitudinal beam 22 can move along the Y-axis direction. The loading and unloading assembly 21 is movably connected to the moving longitudinal beam 22 so as to enable the loading and unloading assembly 21 to move along the third direction, i.e. the loading and unloading assembly 21 can move along the Z-axis direction.
Optionally, as shown in fig. 1 and fig. 4, the feeding and discharging assembly 21 includes a rotating shaft 212, a connecting driving member 213, and at least two feeding and discharging members 211, the rotating shaft 212 can be used to drive the feeding and discharging members 211 to rotate, that is, the connecting driving member 213 drives the rotating shaft 212 to rotate, and the rotation of the rotating shaft 212 drives the feeding and discharging members 211 to rotate. The connecting driving member 213 can be used to drive the rotating shaft 212 to rotate, and a rotating motor can be disposed in the connecting driving member 213, that is, the connecting driving member 213 is specifically driven by the rotating motor to drive the rotating shaft 212 to rotate.
The rotating shaft 212 may be disposed along the first direction, that is, the rotating shaft 212 may be disposed along the X-axis direction, and both ends of the rotating shaft 212 may extend toward the left and right sides of the moving longitudinal beam 22 in the first direction, respectively. The connecting driving member 213 may be connected to a middle portion of the rotating shaft 212, and the connecting driving member 213 is further connected to the moving longitudinal beam 22 to drive the rotating shaft 212 to move along the third direction, i.e. the rotating shaft 212 may move along the Z-axis direction. Each feeding and discharging part 211 is arranged at a position corresponding to a processing station of the processing device 1 and connected to the rotating shaft 212, that is, the feeding and discharging parts 211 and the material rack 12 and/or the positioning mechanism 13 are linearly arranged side by side along the Y-axis direction.
Alternatively, as shown in fig. 4, the feeding and discharging component 211 includes a connection portion 2112 and a suction cup 2111, the connection portion 2112 may be connected to the rotation shaft 212, and the suction cup 2111 may be disposed on a side of the connection portion 2112, where the side is set to be a side where the connection portion 2112 faces a surface of a sheet when rotating, so as to drive the suction cup 2111 to rotate and suck the sheet.
Note that the suction cups 2111 on the respective connection portions 2112 are all located on the same plane, that is, the respective connection portions 2112 are aligned side by side so that the suction cups 2111 on the respective connection portions 2112 can simultaneously suck the sheet. As shown in fig. 4, the connection portions 2112 on the two sides of the loading and unloading robot 2 are not in the same plane, which is intended to be understood by those skilled in the art: the loading/unloading section 211 is different from the connection section 2112 when loading and unloading the sheet on the stack 12 and the table 14.
Further, the suction cup 2111 may employ a vacuum cup. The vacuum chuck has the following advantages: firstly, the vacuum chuck is pollution-free, is particularly environment-friendly, cannot pollute the environment, and does not generate light, heat, electromagnetism and the like; secondly, the workpiece (sheet) is not damaged, and the vacuum chuck is made of rubber materials, so that the workpiece is not damaged when being sucked or put down.
Alternatively, the connection portion 2112 may be directly fixed to the rotating shaft 212, or the connection portion 2112 may be configured to be detachable so that the connection portion 2112 is detachably fixed to the rotating shaft 212. It is understood that when the connection portion 2112 is configured to be detachable, one end of the connection portion 2112 may be configured to have a holding function, such as a holding end of a clip, and the other end of the connection portion 2112 may be configured to have a certain length, such as a holding end of a clip, to provide a space for placing the suction cup 2111. If the sucking disc 2111 in the feeding and discharging component 211 is damaged, the connecting part 2112 can be directly taken down from the rotating shaft 212, the dismounting step is simple, the equipment cannot be damaged, the component is easy to replace, and the whole full-automatic feeding and discharging intelligent CNC machining equipment has more flexibility.
As shown in fig. 1 and 4, further, at least two sets of suction cups 2111 may be provided, and two sets of suction cups 2111 may be provided on opposite sides of the connection portion 2112. In this embodiment, the two groups of suction cups 2111 are respectively a first group of suction cups and a second group of suction cups, when the device is operated, the first group of suction cups and the second group of suction cups can simultaneously feed from the material rack 12 and convey a sheet to the workbench 14, the sheet sucked by the first group of suction cups is a first sheet, the sheet sucked by the second group of suction cups is a second sheet, the first sheet is firstly placed on the workbench 14 for processing, and the first group of suction cups are used for blanking after the first sheet is processed; then the rotating shaft 212 is rotated to enable the second sheet to be located below the first sheet and to be horizontally placed, the second sheet is placed on the workbench 14 to be processed, after the second sheet technician finishes the second sheet, the second group of suction cups are used for blanking, and then the first sheet and the second sheet are conveyed back to the rack 12 to be placed, so that the processing efficiency is improved.
