[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] See also Figure 1-3 The utility model provides a technical solution: a device for cutting a LED rear lamp shade, comprising a cutting platform 1, a fixture bracket 2 fixedly mounted on the upper surface of the cutting platform 1, an electric telescopic rod 3 fixedly connected to the bottom of the fixture bracket 2, an output end bearing of the electric telescopic rod 3 connected to a gripping plate 4, and a pressure sensor 5 fixedly connected to the upper surface of the gripping plate 4 for real-time monitoring of the gripping force;
[0022] An electric telescopic rod 2 7 is fixedly connected to the bottom of the top of the clamp bracket 2, and the output end of the electric telescopic rod 2 7 is fixedly connected to a mounting plate 8. A rotating motor 9 is fixedly connected to the bottom of the mounting plate 8, and a grabbing plate 2 6 is fixedly connected to the shaft end of the rotating motor 9. The grabbing plate 2 6 cooperates with the grabbing plate 1 4 to complete the clamping process of the workpiece.
[0023] The shapes of the clamping surfaces of the first and second gripping plates 4 and 6 are arranged to fit the shapes of the surfaces in contact with the lampshade.
[0024] The cutting platform 1 is located on the upper surface of one side of the clamp bracket 2, and is fixedly connected to a linear motor 10 for lateral movement of the laser cutting position. The sliding output end of the linear motor 10 is fixedly connected to the laser emitter bracket. The right side of the laser emitter bracket is fixedly connected to a control computer 11. The left side of the laser emitter bracket is fixedly connected to a linear motor 2 12 for longitudinal movement of the laser cutting position. A laser emitter 13 is fixedly installed on the left side of the sliding output end of the linear motor 2 12. A laser nozzle 14 is fixedly installed at the bottom of the laser emitter 13 to adjust the laser emission position.
[0025] In this embodiment, first select a suitable clamping point on the workpiece, place the workpiece between the gripping plate 1 4 and the gripping plate 2 6, then start the electric telescopic rod 1 3 and the electric telescopic rod 2 7, and then observe the value displayed by the pressure sensor 5. Since traditional clamps can easily cause cracks on the plastic surface when clamping plastic workpieces if they are too tight, and can easily cause insufficient cutting accuracy if they are too loose, the utility model installs a pressure sensor 5 to observe the clamping force in real time. After multiple tests, a reasonable clamping force value range is obtained. When the value displayed by the sensor reaches the allowable range, the electric telescopic rod 1 3 and the electric telescopic rod 2 7 are stopped. At this time, the workpiece is clamped and there is no damage.
[0026] If rotary cutting is required, the rotary motor 9 can be started. Since the shaft end of the rotary motor 9 is fixedly connected to the gripping plate 2 6, the gripping plate 2 6 and the gripping plate 1 4 rotate accordingly. Under the action of the clamping friction force, the workpiece can be clamped and rotated in a circle for easy cutting.
[0027] Enter the program in the control computer 11 and start it. The slider output ends of the linear motor 10 and the linear motor 2 12 can move horizontally and vertically according to the program settings. The laser nozzle 14 can cut at the set coordinates to complete the cutting process, and finally achieve the purpose of the fixture not damaging the workpiece while clamping the workpiece to ensure cutting accuracy.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
