Description

Technical Field

[0001] The utility model relates to the technical field of keyboard production, in particular to a laser engraving machine capable of automatically loading and unloading materials. Background Art

[0002] When the keyboard is produced, all characters and words need to be printed or engraved on the keycaps. Some characters printed by silk screen printing are very easy to wear out, and the characters disappear after a long period of use, affecting the use. The currently commonly used laser engraving process is to engrave the characters on the keycaps through laser, and the characters will not wear out and disappear after long-term use.

[0003] For example, the patent with publication number CN214392825U discloses a laser engraving mechanism, which positions the workpiece through a positioning module and can effectively channel the large amount of heat generated during the laser engraving process through a heat dissipation module, thereby preventing the high heat of the laser engraving from damaging the workpiece.

The current keyboard laser engraving process requires manual loading and unloading. After loading, the keyboard needs to be manually aligned with the engraving position, and the overall efficiency is low.

[0005] Based on this, the utility model designs a laser engraving machine capable of automatically loading and unloading materials to solve the above problems. Utility Model Content

[0034] Example 1

[0035] Please refer to the instruction manual Figure 1-6 , a laser engraving machine capable of automatically loading and unloading materials, comprising a machine platform 1;

[0036] The machine 1 is equipped with a conveying mechanism 2, a laser engraving machine 3, a feeding assembly 7, an inclined plate 8 and a material receiving box 9, a plurality of receiving tables 4 are evenly spaced and installed on the conveying mechanism 2, a centering and fastening mechanism 5 is installed on the receiving table 4, and a releasing assembly 6 is installed on the receiving table 4, the centering and fastening mechanism 5 and the machine 1;

[0037] The centering and fastening mechanism 5 includes a clamping assembly 51 and a centering assembly 52, and the clamping assembly 51 and the centering assembly 52 are installed on the receiving platform 4;

[0038] In this embodiment, when the laser engraving machine capable of automatic loading and unloading is working normally, the conveying mechanism 2 drives the accommodating table 4 to move in a circular motion. When the accommodating table 4 moves to the position of the feeding component 7, the releasing component 6 releases the clamping component 51 and the centering component 52, so as to facilitate the conveying of the workpiece to be processed from the feeding component 7 to the accommodating table 4; when the workpiece to be processed enters the accommodating table 4, it is clamped by the clamping component 51, and the centering component 52 is used to center the workpiece to be processed, thereby realizing the positioning of the workpiece to be processed; the workpiece to be processed on the accommodating table 4 is conveyed to the bottom of the laser engraving machine 3 by the conveying mechanism 2, and after the engraving is completed by the laser engraving machine 3, the workpiece is continuously conveyed backward until the workpiece is flipped over, and the clamping component 51 and the centering component 52 no longer clamp the workpiece by releasing the component 6, and the workpiece is conveyed to the receiving box 9 through the inclined plate 8; thereby realizing automatic loading and unloading and improving engraving efficiency.

[0039] Example 2

[0040] like Figure 1-6As shown, as a preferred embodiment of the utility model, the clamping assembly 51 includes a placement plate 511, a spring 512, a first limiting rod 513, a centering plate 514 and a slide groove 515.

[0041] The centering assembly 52 includes a rotating disk 521, a first connecting rod 522, a second connecting rod 523, a second limiting rod 524 and a baffle 525. The second limiting rod 524 is fixedly mounted on the accommodating platform 4, and the second limiting rod 524 is limitedly slidably connected to the centering plate 514; the rotating disk 521 is rotatably mounted in the middle of the accommodating platform 4, one end of the first connecting rod 522 is rotatably connected to the rotating disk 521, and the other end of the first connecting rod 522 is rotatably connected to one end of the second connecting rod 523, and the two first connecting rods 522 are centrally symmetrically arranged with the axis of the rotating disk 521 as the center; the other end of the second connecting rod 523 is rotatably connected to the centering plate 514; the baffle 525 is fixedly mounted at one end of the accommodating platform 4;

[0042] A plurality of springs 512 are evenly arranged at equal intervals on the centering plate 514;

[0043] In this embodiment, when the clamping assembly 51 and the centering assembly 52 work normally, the workpiece is pushed onto the placement plate 511 until the attack is blocked by the baffle 525, thereby determining the longitudinal position of the workpiece; the centering plate 514 is pushed to move by the spring 512, and the centering plate 514 slides in the slide groove 515 under the limiting action of the first limiting rod 513, thereby pushing and clamping the workpiece; at the same time, the centering plates 514 on both sides are connected to the turntable 521 through the first connecting rod 522 and the second connecting rod 523, and the centering plates 514 on both sides are displaced in unison through the turntable 521, the first connecting rod 522 and the second connecting rod 523, and the workpiece is clamped in the middle, thereby facilitating subsequent laser engraving.

[0044] Example 3

[0045] like Figure 1-3 , 4 and 5, as a preferred embodiment of the utility model, the conveying mechanism 2 includes a slide rail 21, a slide table 22, a chain 23, a sprocket 24 and a motor 25, the slide rail 21 is fixedly installed on the lower side of the machine 1, the slide table 22 is fixedly connected to the accommodating table 4, and the slide table 22 is limitedly slidably connected to the slide rail 21; the middle part of the slide table 22 is fixedly connected to the chain 23, and the chain 23 is meshedly connected to the sprocket 24; the motor 25 is fixedly installed on the machine 1, and the output end of the motor 25 passes through the machine 1 and is fixedly connected to the sprocket 24;

The push rod 61 is slidably connected with the first release block 63 and the second release block 64.

[0047] In this embodiment, when the conveying mechanism 2 and the release assembly 6 are working normally, the motor 25 drives the chain 23 to perform a circular motion through the sprocket 24, and the chain 23 drives the slide 22 to move. The slide 22 performs a circular motion along the trajectory of the slide 22 under the limiting action of the slide rail 21, thereby driving the accommodating table 4 to perform a circular motion along the trajectory of the slide 22; when the accommodating table 4 moves to the position aligned with the feeding assembly 7, the first release block 63 pushes the push rod 61 to move, and the push rod 61 pushes the turntable 521 to rotate, and the rotation of the turntable 521 drives the centering plate 514 to the accommodating table 4 through the second connecting rod 523 and the first connecting rod 522. The two sides move and the spring is compressed, thereby facilitating the entry of the workpiece; when the workpiece moves toward the laser engraving machine 3, the push rod 61 disengages from the first release block 63, and the spring is reset to center and clamp the workpiece; when the accommodating table 4 moves to the position aligned with the inclined plate 8, the push rod 61 is pushed by the second release block 64, thereby driving the centering plate 514 to move to the two sides of the accommodating table 4 through the turntable 521, the second connecting rod 523 and the first connecting rod 522, and the spring is compressed, so that the centering plate 514 no longer clamps the workpiece, which facilitates the workpiece to fall onto the inclined plate 8 under the action of gravity, and is drawn into the material receiving box 9 through the inclined plate 8; thereby realizing automatic loading and unloading of workpieces.
