[0025] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] 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 different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] like Figure 1-Figure 7 The automatic laser engraving machine for car buttons shown in the figure comprises an engraving machine main operation unit 1 and a conveying unit. A laser engraving assembly 8 is arranged on one side inside the engraving machine main operation unit 1. A rotating upper mold mechanism is arranged on one side inside the engraving machine main operation unit 1 and below the laser engraving assembly 8.

[0028] The conveying unit also includes a No. 1 roller conveyor 2, a No. 2 roller conveyor 34, a No. 3 roller conveyor 35, and an arc belt conveyor 3. The No. 1 roller conveyor 2 and the No. 2 roller conveyor 34 are respectively arranged on both sides of the interior of the engraving machine main operation unit 1. Both ends of the arc belt conveyor 3 are combined with the No. 1 roller conveyor 2 and the No. 2 roller conveyor 34. The No. 3 roller conveyor 35 is arranged inside the engraving machine main operation unit 1 and away from the No. 2 roller conveyor 34. The conveying direction of the roller conveyor 34, the third roller conveyor 35, and the arc belt conveyor 3 are arranged in a U shape. A support frame 5 is fixedly arranged in the middle of the outer side of the arc belt conveyor 3, and an arc track frame 4 is fixedly installed above the support frame 5. An arc gear ring 13 is arranged on the outer wall of the arc track frame 4 away from the support frame 5, and an arc guide rail mechanism is arranged on the inner side of the arc gear ring 13. A fixed seat 14 is connected to the lower side of one end of the arc guide rail mechanism through a first cylinder 15, and chuck mechanisms are arranged at both ends of the outer side of the fixed seat 14.

[0029] The rotary upper mold mechanism includes a second hydraulic cylinder 12 arranged inside the main operating unit 1 of the engraving machine, a frame 11 is fixedly arranged at the telescopic end of the second hydraulic cylinder 12, a first hydraulic cylinder 10 is fixedly arranged inside the frame 11, a driving turntable mechanism 9 is fixedly connected to the telescopic end of the first hydraulic cylinder 10, and a storage tray is arranged at the upper end of the driving turntable mechanism 9;

[0030] From the instruction manual Figure 1 , Figure 2 and Figure 3It can be seen that the first hydraulic cylinder 10 can drive the driving turntable mechanism 9 to receive the material at one end of the second roller conveyor 34, and then the second hydraulic cylinder 12 drives the frame 11 and the first hydraulic cylinder 10 to move in a horizontal direction, so that the driving turntable mechanism 9 can convey the disk loaded with the key to the lower end of the laser engraving assembly 8 for engraving;

[0031] The driving turntable mechanism 9 is composed of a motor gear box and a circular storage tray. The motor gear box can drive the storage tray to rotate, and then the multiple keys loaded on the disk are rotated in a circular direction, so that more keys can be engraved.

[0032] The arc guide mechanism includes an arc groove provided inside the arc gear ring 13, a rotating shaft 36 is movably provided inside the arc groove, and clamping wheels 33 are mounted on both ends of the rotating shaft 36, and the two clamping wheels 33 are in rolling contact with the edges of both sides of the arc rail frame 4, a guide frame 7 is provided in the middle of the inner side of the rotating shaft 36, and a driving mechanism is provided on the inner upper side of the guide frame 7;

[0033] The driving mechanism includes a motor 6 disposed on the inner side of the guide frame 7. A spur gear 32 is disposed at the output end of the motor 6. The spur gear 32 is meshed with the arc gear ring 13. The upper end of the first cylinder 15 is connected to the lower surface of the guide frame 7.

[0034] Reference Manual Attached Figure 1 , Figure 2 , Figure 4 , Figure 7 It can be seen that the motor 6 drives the spur gear 32 to rotate, thereby allowing the spur gear 32 to engage with the arc-shaped gear ring 13. Under the limitation of the clamping wheels 33 at the upper and lower ends of the rotating shaft 36 and the edge of the arc-shaped track frame 4, the overall structure of the motor 6 can be moved to the outside of the arc-shaped track frame 4.

[0035] The chuck mechanism includes a sleeve 17 fixedly arranged on one side of the fixed seat 14, a slide 19 is slidably installed inside the sleeve 17, a traction assembly is arranged above the slide 19, a third cylinder 18 is fixedly arranged above the inside of the slide 19, a pry mechanism is arranged at the telescopic end of the third cylinder 18, a slide rod 21 is slidably installed in the middle of the slide 19, a fixed block 22 is arranged at the front end of the slide rod 21, a spring 23 is arranged outside the slide rod 21 and at the rear end of the fixed block 22, an arc-shaped pad clamp 24 is fixedly arranged at the bottom end of the fixed block 22, and stabilizing members are arranged at both ends of the outer side of the arc-shaped pad clamp 24;

[0036] Reference Manual Attached Figure 5It can be seen that the arc-shaped pad clamp 24 can fit the outer side of the disc under the drive of the traction assembly, and the prying plate mechanism at the lower end also contacts the bottom edge of the disc. However, since the spring 23 and the slide bar 21 are arranged above the arc-shaped pad clamp 24, the prying plate mechanism can be embedded into the bottom of the disc within this elastic spacing as the traction assembly expands and contracts, thereby facilitating the disc to be stably separated from the upper surface of the arc-shaped belt conveyor 3, and the buttons on the surface of the disc will not fall off, and the arc-shaped pad clamp 24 can also clamp the disc in a balanced manner.

[0037] The traction assembly includes a second cylinder 16, which is fixedly arranged outside the fixing seat 14 and above the sleeve 17, and the telescopic end of the second cylinder 16 is connected to the outside of the slide 19;

[0038] Reference Manual Attached Figure 3 and Figure 5 It can be seen that the second cylinder 16 can be moved by telescopically driving the slide 19 to meet the use of different disc diameters.

[0039] The prying mechanism includes a U-shaped rod 31 fixedly arranged at the telescopic end of the third cylinder 18, and multiple tooth angles 29 are arranged on the outer surfaces of both sides of the U-shaped rod 31 and near the lower position. A clamping shaft 28 is rotatably inserted at the lower inner side of the slide 19, and arc gears 30 are arranged on the outer sides of both sides of the clamping shaft 28, and the two arc gears 30 are meshed with the tooth angles 29 at the corresponding positions. Rotating seats 27 are arranged on both ends of the outer side of the clamping shaft 28 and on one side of the arc gear 30, and a chipper 25 is arranged between the two rotating seats 27;

[0040] Reference Manual Attached Figure 4 , Figure 5 and Figure 6 It can be seen that under the lifting and lowering movement of the third cylinder 18, the U-shaped rod 31 will drive the multiple tooth angles 29 on the outer surface to engage with the corresponding arc gears 30, so that the clamping shaft 28 drives the rotating seat 27 and the chipper 25 to pry when they contact the bottom of the disc.

[0041] The stabilizing member includes a guide rod 20 fixedly arranged at one end of the outer side of the arc-shaped pad clamp 24, and a support rod 26 is arranged at the outer side of the slide 19 and at a position corresponding to the guide rod 20, and the guide rod 20 and the support rod 26 are slidably connected;

[0042] Reference Manual Attached Figure 5 It can be seen that in order to make the arc-shaped pad clip 24 cooperate with the elastic pressure of the spring 23 to be more stable, the guide rod 20 is correspondingly slidably inserted into the interior of the bracket rod 26.

[0043] Working principle: When in use, multiple discs with buttons installed are conveyed to the surface of the arc belt conveyor 3 through the No. 1 roller conveyor 2. Under the setting of the support frame 5 and the arc rail frame 4, the arc guide mechanism can drive the first cylinder 15 at the lower end and the fixed seat 14 to move along the conveying direction of the arc belt conveyor 3. Therefore, when the main operation unit 1 of the engraving machine stops, the spacing between the discs can be adjusted, and the sticking problem caused by the contact between the bottom of the disc and the arc belt conveyor 3 can be solved. The second cylinder 16 can drive the slide 19 to move closer or farther from each other according to the diameter of the disc until the corresponding arc pad clamp 24 can wrap around both sides of the disc. Its clamping drives the installed key disc to move, and in order to avoid the problem of the bottom of the disc sticking, which causes the clamped disc to be unbalanced, and the problem of the key falling off the surface of the disc mold due to shaking and lifting the disc, the third cylinder 18 can drive the U-shaped rod 31 to move downward, and the tooth angle 29 corresponding to the outer surface of the U-shaped rod 31 can engage with the arc gear 30, so that the rotating seat 27 and the chip 25 can be pried at the bottom of both sides of the disc. Since an elastic part is provided at the rear end of the arc pad clamp 24, the disc can be stably detached from the upper surface of the arc belt conveyor 3, and the installed keys will not fall from the mold surface. At this point, the working efficiency of the engraving machine main operation unit 1 can be fully improved.

[0044] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
