[0042] In order for those skilled in the art to better understand the technical solutions of the present disclosure, the present disclosure will be described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure and do not limit the present disclosure. ​

[0044] Those skilled in the art should understand that in the disclosure of the present application, the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like is based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element indicated must have a particular orientation, be constructed and operated in a particular orientation, therefore the above terms cannot be understood as a limitation of the present application.

[0045] The present application will be further described in detail below in conjunction with the drawings, see as Figures 1 to 7 Description.

[0046] The present application provides a kind of laser cutting sheet material loading device 1, it is used to the sheet workpiece 2 in laser cutting device is loaded, workpiece 2 is automatically conveyed to laser cutting station;Due to the particularity of laser cutting sheet material, therefore, when laser processing, sheet material can only be conveyed piece by piece, the present application is loaded for this kind of sheet material needing laser cutting, can effectively reduce the interval length of loading, to improve the transmission rate of sheet material, improve work efficiency.

[0047] Specifically, as Figures 1 to 3As shown, the feeding device 1 for laser cutting sheet materials (hereinafter referred to as the feeding device 1) includes a worktable 11, a feeding mechanism 12, and a feeding mechanism 13, which are arranged on the worktable 11. The feeding mechanism 12 can temporarily store at least two workpieces 2 at the same time, and when storing workpieces 2, the workpieces 2 are arranged horizontally from the feeding station to the laser cutting station. The feeding mechanism 13 can push the workpieces 2 on the feeding mechanism 12 toward the laser cutting station to ensure the continuous supply of material to the laser cutting station and reduce the interval time between workpieces 2 feeding. After the laser cutting device processes the workpiece 2 at the processing station on the feeding mechanism 12, the feeding mechanism 13 can push at least one remaining workpiece 2 to be processed to the laser processing station for processing, which provides a certain amount of processing time for the workpieces 2. The feeding mechanism 12 provides buffer time and placement space. During the buffer time, the operator or the feeding mechanism can place the new workpiece 2 in the empty position of the feeding mechanism 12. The feeding mechanism 12 can be fed again before all the workpieces 2 on the feeding mechanism 12 are processed. This allows the feeding mechanism 12 to continuously guide the workpieces 2 to the laser cutting station. The laser cutting device can also continuously process the workpieces 2, greatly reducing the efficiency problems caused by the feeding interval time, thereby greatly improving the overall working efficiency of the feeding device 1.

[0048] It should be noted that in this application, the displacement parallel to the workpiece 2 moving from the loading station to the laser cutting station on the loading mechanism 12 is taken as the X-axis, the direction parallel to the X-axis on the worktable 11 is taken as the Y-axis, and the direction perpendicular to the worktable 11 is taken as the Z-axis. The X-axis, Y-axis, and Z-axis share a common reference coordinate system to facilitate the description of the relationship between the various mechanisms in this application.

The two feeding platforms 121 are arranged opposite each other to form a horizontally limited feeding space. The size of the feeding space is set according to the size of the sheet material. The two ends of the sheet material are attached to the two feeding platforms 121 at both ends, and the middle part of the sheet material is suspended underneath, so that the laser cutting device will not accidentally cut the feeding platform 121 when cutting the sheet material. Along the X-axis, the length of the feeding platform 121 is greater than X1, and the length of the sheet material is X2, where X1>X2, so that the feeding space can simultaneously hold at least two horizontally arranged workpieces 2. Preferably, X1>2.5X2, so that the sheet material will not stick together in the feeding space, avoiding the laser cutting device from affecting the other piece when cutting one piece.

[0050] Furthermore, the material placement platform 121 is described in more detail; such as...
