DETAILED DESCRIPTION

[0018] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0020] In the prior art, when a 3D laser cutting device is used to cut a workpiece, it is necessary to position the workpiece before laser cutting. If the workpiece is not positioned, the workpiece will be displaced, affecting the accuracy of laser cutting. In the process of positioning the workpiece, since laser cutting of workpieces of different thicknesses is required, when processing thin workpieces, the traditional 3D laser cutting device cannot effectively support the thin workpiece, resulting in the phenomenon of cutting offset of the thin workpiece during the cutting process. At the same time, when processing other workpieces, if the width of the workpiece is too wide, the traditional positioning mechanism cannot be adjusted according to the width of the workpiece, and the wide workpiece cannot be effectively positioned, thereby affecting the processing efficiency of the 3D laser cutting device.

[0021] The purpose of the present invention is at least that when the laser cutting equipment is processing the workpiece, affected by the thickness of the workpiece itself, when the workpiece is thin, the workpiece switching mechanism 300 drives the lateral support pallets 405 on both sides to move to both sides, and the multi-point support pallet 304 will move to the middle of the sound insulation shell 101. The multi-point support pallet 304 has more contact points than the lateral support pallet 405, and the contact points of the multi-point support pallet 304 can better fit the lower surface of the thin workpiece and support it to prevent deviation during the processing. Subsequently, the positioning frame 308 can be used to position the thin workpiece for processing, so that the lower surface of the thin workpiece can better fit the multi-point support pallet. The contact point of plate 304 can improve the efficiency and stability of laser cutting, and can effectively prevent the displacement and offset of thin workpieces during processing. When processing some normal thickness and thicker workpieces through the width adjustment component 400, the two lateral support plates 405 can be moved to the middle and merged into a whole piece to process normal thickness and thicker workpieces. At the same time, by adjusting the distance between the two lateral support plates 405, the width adjustment effect can be achieved according to the width of the workpiece, thereby making the positioning equipment have higher versatility, and can be adjusted when facing workpieces of different widths and thicknesses, thereby improving the practicability and processing efficiency of the device.

The multi-point support plate 304 has more contact points than the transverse support plate 405, so the multi-point support plate 304 is more suitable for supporting thin workpieces, and the transverse support plate 405 is more suitable for supporting workpieces of normal thickness or thicker thickness. The multi-point support plate 304 and the transverse support plate 405 can be adjusted between the workpiece switching mechanism 300, and they can be switched according to different workpieces, thereby improving the versatility and practicality of the workpiece positioning device.
