The previous process is the feeding process, and the next process is the flipping process. process. Obviously, the feeding device 30 can also be split into a feeding device 30 and a turning device according to the process, and the split feeding device 30 can also be used as a feeding device 30 of other material handling devices. Examples are not particularly limited.

As shown in Figures 3, 6, 8 and 9, a jacking station and a feeding station are formed in the feeding device 30 in the embodiment of the present invention. The feeding device 30 may include two lifting mechanisms 31 disposed opposite to each other, and an overturning mechanism 32 disposed adjacent to the lifting mechanisms 31 .

In one embodiment, referring to FIG. 6 , the two lifting mechanisms 31 are oppositely arranged on both sides in the width direction of the conveyor belt 21 , and the lifting mechanisms 31 include a jacking block 311 and a lifting drive assembly 312 . The lifting drive assembly 312 drives the jacking block 311 to reciprocate up and down, the jacking block 311 is close to the side edge of the conveyor belt 21, and the two jacking blocks 311 arranged oppositely form the jacking of the material storage tray 23.

In one embodiment, the above-mentioned turning mechanism 32 may include a fixing frame 321 and a turning component 322 connected to the fixing bracket 321, the turning component 322 is provided with one or more suction cups 325, and the turning component 322 is configured to rotate along the fixed frame 321, so that the suction cup 325 on it picks up the material on the material storage tray 23 from the jacking station, and the turning assembly 322 rotates and resets after the material is picked up. , so that the surface of the material to be engraved is placed on the suction cup 325 downwards, the overturning mechanism 32 can make the surface to be engraved face downward, and then the transfer device 40 transfers the material to the positioning device 50 during the transfer process In the middle, the laser engraved surface faces the positioning panel 511 for precise positioning.

In one embodiment, the above-mentioned fixing bracket 321 of the turning mechanism 32 may include two oppositely arranged brackets, the two brackets are respectively arranged on both sides of the conveyor belt 21 in the width direction, and the above-mentioned brackets are mounted on the two brackets. The overturn assembly 322.

The turning arm 324 and the turning shaft 323 can be integrally formed or separately connected and fixed. One or more cantilever frames, each of which is provided with one or more soft suction cups 325 . At a certain moment, the turning arm 324 is horizontally arranged on one side of the turning shaft 323, the material storage tray 23 is arranged on the other side of the turning tray, and the suction cup 325 on the turning arm 324 deviates from the The conveyor belt 21 forms a loading station.

When the material storage tray 23 is lifted from the initial position to the position, the turning arm 324 rotates along the central axis of the turning shaft 323, driving the suction cup 325 to rotate toward the direction of the conveyor belt 21, so that the suction cup 325 Pick up the material by adsorption, see Figure 8; after the material is picked up, the turning arm 324 is rotated and reset along the central axis of the turning shaft 323, and the empty material storage tray 23 is lowered and reset with the jacking block 311, The surface of the material to be laser-engraved faces the conveyor belt 21, as shown in FIG. 9 .

Thus, the suspended arm of the support serves as the rotation axis of the turning arm 324, and the turning arm 324 is flexibly connected with the hanging arm of the support, thereby realizing the adsorption and turning of the material.

What needs to be explained here is that the lifting mechanism 31 can only be lowered and reset after the material carried on it is picked up by the turning mechanism 32, that is, when there is no material on the jacking station. This design can form a closed-loop feedback , when the material is conveyed to the turning mechanism 32, it proves that the material on the lifting mechanism 31 has indeed been conveyed away, which can prevent the delivery from being in place, or "snatching" the material on the lifting mechanism 31 has not been picked up As the price increase mechanism falls back, the material feeding disorder is caused, thereby reducing the possibility of errors in production.

That is, the feeding device 30 first lifts and lifts the material and then flips and loads the material, while the unloading device 70 first flips and feeds the material and then lifts and unloads the material.

Those skilled in the art should know that when the turning mechanism 32 is used as an independent material turning device, it may be necessary to provide a feeding mechanism on its feeding side to feed materials to the feeding place of the turning mechanism 32 .

When the feeding device 30 is used as a part of a complete set of material automatic packaging equipment, the specific process of related operations after the feeding device 30 loads the materials to be engraved can refer to the relevant content in the following embodiments.

The material conveying device is arranged in a straight line on one side of the 7 sets of laser engraving equipment , the 7 sets of laser engraving equipment are lined up on the same side of the material conveying device. One end of the material conveying device is used for loading materials, and the other end is equipped with a dust removal device to remove dust from the completed laser engraving materials;

In the initial state, 7 sets of laser engraving equipment are on standby, and the material is loaded on the conveyor belt of the material conveying device. The distance between each material is the same. When the first material placed on the conveyor belt reaches the 7th laser engraving equipment (along The material conveying direction of the material conveying device is named after the 7 devices in turn. The arrow P in Figure 12 indicates the material conveying direction. The 7 laser engraving devices are: the first laser engraving device, the second laser engraving device, the 3 sets of laser engraving equipment, the 4th set of laser engraving equipment, the 5th set of laser engraving equipment, the 6th set of laser engraving equipment, the 7th set of laser engraving equipment, of which the 7th set of radium engraving equipment is close to the dust removal device 90, and the 6th set The machines under the engraving equipment are not displayed, but it is understandable that the machines under the 7 laser engraving equipment are actually the same) when the jacking position means the jacking of the first 1-6 laser engraving equipment in front There are also materials on the workstation.
