[0038] When the loading assembly 7 pushes the product 5 to be processed onto the pushing shaft 4, the rotation of the pushing screw 12 drives the product 5 to be processed to abut against the positioning plate 3 for positioning;

[0039] Negative pressure adsorption component, the transmission box 14 is also equipped with a negative pressure adsorption component, which is used to perform adjustable negative pressure suction on the suction hole 2 13 and the suction hole 1 2, so that the product 5 to be processed moves closely against the push shaft 4, and the product 5 to be processed is closely abutted against the positioning plate 3;

[0040] The laser engraving component 1 is also installed on the transmission box 14.

After the laser engraving component 1 has performed laser engraving on the product 5 to be processed, the positioning and unloading component is also used to push the product 5 to be processed onto the conveying component 6.

[0041] In the embodiment of the present invention, the product 5 to be processed before and after processing can be conveyed by the conveying component 6, so as to realize efficient processing of the product 5 to be processed; the product 5 to be processed can be pushed onto the pushing shaft 4 by the loading component 7, and then the pushing shaft 4 is driven to rotate by the driving component, and the rotation of the pushing screw 12 drives the product 5 to be processed to be positioned against the positioning plate 3, and then the laser engraving component 1 can be started to perform laser engraving on the product 5 to be processed positioned by the positioning plate 3, and after the laser engraving component 1 performs laser engraving on the product 5 to be processed, the positioning unloading component is also used to push the product 5 to be processed onto the conveying component 6, so as to realize automatic loading and unloading processing of the product 5 to be processed.

[0042] In summary, the multi-station laser engraving equipment with automatic loading and unloading, through integrated conveying, loading, positioning, laser engraving and unloading components, combined with adjustable negative pressure adsorption and multi-station adjustment functions, realizes an efficient, accurate and automated processing flow of the product 5 to be processed, greatly improving production efficiency and flexibility.

[0043] like Figure 1-Figure 3 As shown, as a preferred embodiment of the present invention, the material unloading adjusting telescopic cylinder 16 is perpendicular to the conveying assembly 6 and is horizontally arranged, two material unloading adjusting telescopic cylinders 16 are arranged, and the cylinder body of the material unloading adjusting telescopic cylinder 16 is fixedly connected to the top of the transmission box 14 through the cylinder seat 15, and the output ends of the two material unloading adjusting telescopic cylinders 16 are fixedly connected to the two side branches of the U-shaped frame 23.

[0044] The middle branch of the U-shaped frame 23 is in a horizontal state, and a fastening bolt 25 for locking the sleeve 24 after adjustment is installed to ensure its stability.

[0045] The positioning plate 3 adopts an L-shaped structure, the first branch of the positioning plate 3 is arranged perpendicular to the conveying component 6, and the second branch of the positioning plate 3 is arranged parallel to the conveying component 6. The suction hole 2 is opened on the side of the first branch away from the moving direction of the conveying component 6 and the side of the second branch close to the conveying component 6, so as to ensure the adsorption reliability of the product 5 to be processed; the length of the first branch is smaller than the length of the second branch, so that the product 5 to be processed can be reliably positioned while the product 5 to be processed can be separated from the positioning plate 3 and stay on the conveying component 6, that is, the contact length of the first branch with the product 5 to be processed is reduced, thereby reducing friction.

[0046] like Figure 1 , Figure 4 and Figure 5 As shown, as a preferred embodiment of the present invention, an air cavity 36 and a transmission cavity 39 are respectively opened on the inner side of the transmission box 14, the push shaft 4 is rotatably connected to the transmission box 14, and the end of the push shaft 4 away from the conveying assembly 6 extends into the air cavity 36; the driving assembly includes a motor 34, a transmission rod 35, a double-groove pulley 37 and a transmission belt 38, and a motor cavity 33 is also opened in the transmission box 14 on the side of the air cavity 36 away from the transmission cavity 39, and a motor 34 is fixed in the motor cavity 33, and the output shaft of the motor 34 extends into the air cavity 36, and a plurality of transmission rods 35 are circumferentially distributed and fixed to the end of the output shaft of the motor 34, and the other end of the transmission rod 35 is fixedly connected to the end of one of the push shafts 4; a double-groove pulley 37 is also fixed on the push shaft 4 in the transmission cavity 39, and two adjacent double-groove pulleys 37 are connected by a transmission belt 38 for transmission, as shown in FIG. Figure 4 As shown in the figure, they are connected in sequence, so that after the motor 34 drives one pusher shaft 4 to rotate, the double-groove pulley 37 and the transmission belt 38 are used to drive all the pusher shafts 4 to rotate in the same direction.

[0047] Preferably, when the motor 34 drives the pushing shaft 4 to rotate, the pushing screw 12 drives the product to be processed 5 to move and abut against the first branch and the second branch of the positioning plate 3. The structure of the pushing screw 12 can drive the product to be processed 5 in two directions, so that the product to be processed 5 abuts against the first branch and the second branch of the positioning plate 3.

[0048] like Figure 1-Figure 5 As shown in the figure, as a preferred embodiment of the present invention, the negative pressure adsorption component includes a negative pressure device 17, a solenoid valve 18, a negative pressure pipe 19, a solenoid valve 20, a multi-way pipe 21 and a hose 22. The negative pressure device 17 is fixed to the top of the transmission box 14. The negative pressure device 17 has two negative pressure ports, and the two negative pressure ports are respectively equipped with a negative pressure pipe 19 and a multi-way pipe 21.

For the conventional arrangement of the opening of the inner cavity of the positioning plate 3, it is sufficient to ensure that the hose 22 is connected to all the suction holes 2, and there is no limitation.

[0049] Preferably, after the laser engraving assembly 1 has performed laser engraving on the product 5 to be processed, the negative pressure device 17 stops working, releasing the negative pressure suction state of the suction hole 1 2 and the suction hole 2 13 , which helps the positioning plate 3 to reliably push the product 5 to be processed onto the conveying assembly 6 .

[0050] When in use, the electromagnetic valve 18 and the electromagnetic valve 20 can be flexibly adjusted to facilitate reliable adjustment and control; when the negative pressure tube 19 draws negative pressure to the air cavity 36, the transmission rod 35 ensures reliable transmission and is connected with all the suction holes 13 on the pushing shaft 4, so that the suction holes 13 generate negative pressure to stably adsorb the product 5 to be processed, thereby ensuring the reliability of the transmission of the pushing screw 12 to the product 5 to be processed; when the multi-way tube 21 draws negative pressure to the hose 22, the hose 22 can adapt to the movement of the positioning plate 3, and the negative pressure generated by the suction hole 12 can reliably adsorb the positioned product 5 to be processed, thereby ensuring stability.

A gap is set between the loading push plate 11 and the upper surface of the conveying component 6. The loading push plate 11 is also perpendicular to the loading telescopic cylinder 9. The loading push plate 11 is driven by the loading telescopic cylinder 9 to move, so that a plurality of products to be processed 5 on the conveying component 6 can be pushed onto the pushing shaft 4. Setting the loading push plate 11 to be detachable is conducive to the loading push plate 11 pushing the corresponding number of products to be processed 5 and the positioning plate 3 onto the pushing shaft 4, which is stable and reliable.

[0052] The laser carving component 1 includes a laser carving support plate 26, a fixing bolt 27, a laser carving translation and telescopic cylinder 28, a laser carving lifting and telescopic cylinder 29, a connecting plate 30, a laser carving cross plate 31 and a laser carving machine head 32.
