[0002] The loading structure of a laser marking machine refers to the mechanism or system in the laser marking machine that is responsible for placing the workpiece (usually a flat or curved material) in the marking position. This structure plays a vital role in the laser marking process because it affects the marking accuracy, speed and efficiency.

[0003] At present, the common loading method is to use the high-frequency vibration generated by the vibrating plate to create friction between the products, or to use the height difference created by the telescopic plate of the lifting machine to rely on the friction of the products to achieve loading. The above two methods both involve friction, but some products have special requirements on their surface, and the surface cannot have defects such as abrasions, scratches and scrapes. The above two loading methods cannot be used.

[0004] Therefore, the utility model provides an improved feeding structure of a laser marking machine to solve the above problems. Utility Model Content

[0012] Beneficial Effects

[0013] The utility model provides an improved feeding structure of a laser marking machine. Compared with the prior art, it has the following beneficial effects:

[0014] (1) The improved loading structure of the laser marking machine is positioned by moving the laser head left and right and moving the laser head forward and backward. The X-axis high-precision module moves to the left positioning point, and then the Z-axis high-precision module descends to the high and low positioning points. The Y-axis high-precision module moves forward so that the support on the X-axis high-precision module is inserted under the stacking tray, and then the Z-axis high-precision module lifts the stacking tray upward. In this loading process, it can avoid the defects of scratches, abrasions and stills and scrapes on the material surface caused by friction loading, so as to meet the requirements of some products that their surfaces must be kept smooth.

[0015] (2) The improved laser marking machine loading structure enables multiple stacking pallets to be stacked together through the cooperation of the notch slots on the pallet bottom plate and the fixed plug posts. Due to the cooperation of the movable block movably connected by the limit post inside the notch slot and the elastic component at the bottom of the fixed plug post, when the material support is inserted in the lifting and placing of the stacking pallet, the material on the stacking pallet will not be horizontally offset, thereby avoiding inaccurate marking due to material offset during the marking process, resulting in an increase in the defective rate of products.

[0026] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0027] Working principle: When working, the high-precision slide module is used to form an XYZ gantry structure. The X-axis high-precision module 6 is a left and right walking material discharge mechanism, the Z-axis high-precision module 5 is a high and low material collection structure, and the Y-axis high-precision module 12 is a front and rear material collection structure. The X-axis high-precision module 6 is equipped with a material collection insert 16. The materials are manually placed neatly in the stacking tray 13. When the worker stacks the products on the left side of the machine, press the start button, adjust the position of the laser light path 9 by adjusting the column 10 up and down by the laser head, and at the same time, move the laser head left and right through the module 7 and the front of the laser head. Afterwards, the moving module 8 is positioned, the X-axis high-precision module 6 moves to the left positioning point, and then the Z-axis high-precision module 5 will drop to the high and low positioning points, and the Y-axis high-precision module 12 moves forward so that the support plug 14 on the X-axis high-precision module 6 is inserted under the stacking tray 13, and then the Z-axis high-precision module 5 lifts the stacking tray 13 upward to separate the stacking tray 13 from the stacking tray 13 below, and then the X-axis high-precision module 6 moves to the right to the right marking point. After the top visual inspection system 11 detects the material tray, the laser marking machine starts marking, and waits for After the marking is completed, the Z-axis high-precision module 5 will descend and place the material tray on the right-hand stepping conveyor 2. The stepping conveyor 2 is equipped with a high-precision sensor. When the stacking tray 13 is placed on the stepping conveyor 2, the stepping conveyor 2 starts to transport the marked products to the packaging table 3, and the packaging workers complete the packaging. In the process of loading materials, it can avoid the defects of scratches, abrasions and stills and scratches on the surface of the material 16 caused by friction loading, so as to cope with the requirement that some products must keep their surface smooth. At the same time, through the bottom plate of the tray The cooperation between the notch slot 1302 and the fixed plug 1306 on 1301 allows multiple stacking pallets 13 to be stacked in combination. Due to the cooperation between the movable block 1304 movably connected to the limiting column 1303 inside the notch slot 1302 and the elastic component 1307 at the bottom of the fixed plug 1306, when the supporting plug 14 lifts and places the stacking pallet 13, the material 16 on the stacking pallet 13 will not be horizontally offset, thereby avoiding inaccurate marking due to the offset of the material 16 during the marking process, resulting in an increase in the defective rate of the product.
