[0002] A lampshade is a cover that is placed around the flame of a lamp or on a bulb to focus light or protect against wind and rain. The lampshade is not only placed on the lamp to gather light, but also can prevent electric shock and protect the eyes. With the progress of life and people's demand for various aesthetics, lampshades are now often engraved with various patterns or cut into different shapes to enhance the appearance. Lasers are generally used to carve or cut lampshades. When the laser lampshade cutting machine on the market is cutting the lampshade, since the lampshade is directly placed on the processing position and is processed and cut by the laser, the lampshade is prone to shaking or offset during processing, thereby affecting the cutting accuracy and processing effect, and further affecting the quality of the finished product after the lampshade is processed.

[0019] 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.

[0020] See also Figure 1-3 The utility model provides a technical solution: a laser lampshade cutting machine, comprising a frame 1, on which a mounting mechanism 2, a positioning mechanism 3 and a laser cutting device 4 are provided. The mounting mechanism 2 is used to mount the lampshade thereon for laser cutting processing. The positioning mechanism 3 is used to tighten the lampshade when the lampshade is mounted on the mounting mechanism 2, thereby keeping the lampshade stable and avoiding its deviation during processing and affecting the processing quality. The laser cutting device 4 is used to emit laser to directly carve or cut the lampshade.

[0021] A transmission device is also provided on the frame 1, which includes a conveying track 10 installed with the frame 1, a conveying platform 11 slidingly matched with the conveying track 10, and a conveying motor 12 fixedly installed with the conveying platform 11. The driving end of the conveying motor 12 is matched with the conveying track 10 for transmission. The mounting mechanism 2 includes a mounting seat 20 fixedly mounted with the conveying platform 11, a chuck 21 connected with the mounting seat 20, and a rotating motor 22 connected to the chuck 21 for driving the chuck 21 to rotate. The transmission device is mainly used to enable the conveying motor 12 to move between the conveying track 10 after the lampshade is installed. Transmission occurs to transport the installation mechanism 2 on the transfer table 11 to the bottom of the laser cutting device 4 for processing. When installing the lampshade, since there is a wiring hole on the top of the lampshade, the chuck 21 will be provided with a positioning roller clamped and fixed thereto. The positioning roller is passed through the wiring hole to install the lampshade on the positioning roller so that the positioning roller carries the lampshade for cutting processing. Since the side of the lampshade is elliptical, the rotating motor 22 needs to drive the chuck 21 to rotate during processing, so that the positioning roller drives the lampshade to rotate, thereby enabling the side of the lampshade to be processed in all directions.

[0022] The mounting mechanism 2 also includes an adaptive angle correction device, wherein the adaptive angle correction device includes a support platform 23 connected to the mounting seat 20, and the rotating motor 22 is installed on the support platform 23. Both sides of the support platform 23 are provided with waist-shaped holes 24. Because the support platform 23 and the mounting seat 20 are connected by screws, the waist-shaped holes 24 are provided on both sides of the support platform 23. The locking position between the screws and the waist-shaped holes 24 can be adjusted to change the inclination angle between the support platform 23 and the mounting seat 20, thereby changing the inclination angle between the rotating motor 22 and the chuck 21 and the positioning roller relative to the horizontal plane. In this way, when the lampshade is mounted on the mounting mechanism 2 for processing, all-round angle processing can be performed.

[0023] The positioning mechanism 3 and the mounting mechanism 2 are arranged correspondingly in the horizontal direction. The positioning mechanism 3 includes a tightening cylinder 30 and a positioning block 31. A connecting shaft 32 connected to the driving end of the tightening cylinder 30 is provided, and the positioning block 31 is connected to the connecting shaft 32. A connecting plate 33 is also provided on the back side of the positioning block 31. The connecting plate 33 and the connecting shaft 32 are connected by a pin 34. Since a pin 34 is inserted between the connecting plate 33 and the connecting shaft 32, the connecting plate 33 and the connecting shaft 32 can rotate, so that the inclination angle between the positioning block 31 and the connecting shaft 32 can also be changed, so that when the inclination angle of the lampshade relative to the horizontal plane is changed by the adaptive angle correction device, the lampshade can be tightened and positioned again by changing the inclination angle of the positioning block 31.

[0024] The laser cutting device 4 includes a gantry 40 located above the frame 1, a translation rail 41 connected to the gantry 40, and a laser box 42 that slides with the translation rail 41. A longitudinal rail 43 is also provided on the laser box 42. The longitudinal rail 43 is also provided with a laser head 44 that slides and rises with the laser box 42. The laser box 42 can slide and translate on the translation rail 41 to change the position of the laser head 44, so that the lampshade can be translated and cut or engraved. By providing the longitudinal rail 43, the laser head 44 can be driven to descend, so that the lampshade can be engraved and silk-screened more accurately.

[0025] The working principle of the utility model is as follows: when the lampshade needs to be carved or cut, the chuck 21 is first passed through the open end of the lampshade, and the positioning roller clamped and fixed by the chuck 21 is passed through the wiring hole at the top of the lampshade, so that the lampshade is installed on the chuck 21. Then the transmission device is started to transport the mounting mechanism 2 to the bottom of the laser cutting device 4, so that the lampshade is moved to the position to be processed by the laser, and then the tightening cylinder 30 is used to drive the positioning block 31 to tighten the top of the lampshade, so that the lampshade is clamped between the positioning block 31 and the chuck 21, so that the lampshade is fixed on the chuck 21. It remains stable during processing to ensure the processing quality, and then the laser box 42 is translated on the translation track 41 or the laser head 44 is raised and lowered on the longitudinal track 43, thereby driving the laser head 44 to cut or carve the lampshade. By providing a positioning mechanism 3 on the frame 1, when the lampshade is installed on the mounting mechanism 2 and the laser cutting device 4 is used for cutting, the tightening cylinder 30 can drive the positioning block 31 to tighten and position the lampshade, so that the lampshade remains stable during the processing, thereby ensuring the cutting accuracy and processing quality.

[0026] 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.
