[0032] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0033] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0034] As Figures 1-3 shown, a multi-station laser engraving device with automatic loading and unloading provided by an embodiment of the present invention includes a base 8. A conveyor component 6 for conveying a product 5 to be processed is provided on the upper side of the base 8. A conventional conveyor belt can be used for the conveyor component 6. Preferably, the two sides of the conveyor component 6 are rounded to facilitate the loading and unloading of the product 5 to be processed and avoid jamming. It further includes:

[0035] A transmission box 14 is fixed on the base 8 on one side of the conveyor component 6. A plurality of pushing shafts 4 are uniformly arranged and installed on the side of the transmission box 14 close to the conveyor component 6.

[0037] Positioning and blanking assembly. A positioning and blanking assembly is also installed on the transmission box 14. The positioning and blanking assembly includes a positioning plate 3, a blanking adjustment telescopic cylinder 16, a U-shaped frame 23, and a sleeve 24. The blanking adjustment telescopic cylinder 16 is fixed on the transmission box 14. The output end of the blanking adjustment telescopic cylinder 16 is fixed with a U-shaped frame 23.

A plurality of first suction holes 2 are also formed on the side of the positioning plate 3 close to the conveying assembly 6.

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

[0039] Negative pressure adsorption assembly. A negative pressure adsorption assembly is also installed on the transmission box 14. The negative pressure adsorption assembly is used for adjustable negative pressure suction on the second suction holes 13 and the first suction holes 2, so that the product to be processed 5 closely adheres to the pushing shaft 4 for movement, and the product to be processed 5 is in close contact with the positioning plate 3.

[0040] Laser engraving assembly 1. A laser engraving assembly 1 is also installed on the transmission box 14. The laser engraving assembly 1 is used for laser engraving the product to be processed 5 positioned by the positioning plate 3. After the laser engraving assembly 1 laser engraves the product to be processed 5, the positioning and blanking assembly is also used to push the product to be processed 5 onto the conveying assembly 6.

[0041] In the embodiment of the present invention, the conveying assembly 6 can convey the product to be processed 5 before and after processing, so as to realize the efficient processing of the product to be processed 5; the feeding assembly 7 can push the product to be processed 5 onto the pushing shaft 4, and then the driving assembly drives the pushing shaft 4 to rotate. The rotation of the pushing screw 12 drives the product to be processed 5 to abut against the positioning plate 3 for positioning. Subsequently, the laser engraving assembly 1 can be started to laser engrave the product to be processed 5 positioned by the positioning plate 3. After the laser engraving assembly 1 laser engraves the product to be processed 5, the positioning and blanking assembly is also used to push the product to be processed 5 onto the conveying assembly 6, realizing the automatic loading and unloading processing operation of the product to be processed 5. In addition, the negative pressure adsorption assembly can perform adjustable negative pressure suction on the second suction holes 13 and the first suction holes 2, so that the product to be processed 5 closely adheres to the pushing shaft 4 for movement, and the product to be processed 5 is in close contact with the positioning plate 3, improving the reliability of the transmission and positioning of the product to be processed 5; the blanking adjustment telescopic cylinder 16 can not only adjust the position of the positioning plate 3 to match the laser engraving assembly 1, but also push the product to be processed 5 onto the conveying assembly 6; it is specified that there are multiple sleeves 24 and they can be adjusted and slid, enabling multi-station laser engraving processing and adapting to the positioning processing requirements of different models of products to be processed 5, which is flexible and convenient.

[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 Figures 1-3 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, after the motor 34 drives the material pushing shaft 4 to rotate, the material pushing screw 12 drives the product to be processed 5 to move and abut against both the first branch and the second branch of the positioning plate 3. The structure of the material pushing screw 12 can drive the product to be processed 5 in two directions, so that the product to be processed 5 abuts against both the first branch and the second branch of the positioning plate 3.

[0048] As Figures 1-5 shown, as a preferred embodiment of the present invention, the negative pressure adsorption assembly includes a negative pressure device 17, a first electromagnetic valve 18, a negative pressure pipe 19, a second electromagnetic 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 a negative pressure pipe 19 and a multi-way pipe 21 are respectively installed on the two negative pressure ports. A first electromagnetic valve 18 and a second electromagnetic valve 20 are respectively installed on the negative pressure pipe 19 and the multi-way pipe 21. The end of the negative pressure pipe 19 away from the negative pressure device 17 is fixed to the top of the transmission box 14, and the negative pressure pipe 19 communicates with the air cavity 36. The second suction hole 13 communicates with the air cavity 36 through the inner cavity of the material pushing shaft 4; the multi-way pipe 21 has a plurality of branches corresponding to the number of positioning plates 3, and the plurality of branches are respectively connected to the top of the positioning plate 3 through a hose 22, and the hose 22 communicates with the first suction hole 2 through the inner cavity of the positioning plate 3. For the conventional arrangement of the inner cavity of the positioning plate 3, it is only necessary to ensure that the hose 22 communicates with all the first suction holes 2, and no limitation is made.

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

[0050] During application, flexible adjustment can be performed through the first electromagnetic valve 18 and the second electromagnetic valve 20, which is convenient for reliable adjustment and control; when the negative pressure pipe 19 sucks negative pressure on the air cavity 36, the transmission rod 35 ensures reliable transmission and communicates with all the second suction holes 13 on the material pushing shafts 4, so that the second suction holes 13 generate negative pressure to stably adsorb the product to be processed 5, ensuring the reliability of the transmission of the material pushing screw 12 to the product to be processed 5; when the multi-way pipe 21 sucks negative pressure on the hose 22, the hose 22 can adapt to the movement of the positioning plate 3, and the first suction hole 2 generates negative pressure to reliably adsorb the positioned product to be processed 5, ensuring stability.

[0051] As Figure 1 and Figure 6As shown, as a preferred embodiment of the present invention, the feeding assembly 7 includes a feeding telescopic cylinder 9, a feeding support 10, and a feeding push plate 11. On the base 8 on the side of the conveying assembly 6 away from the transmission box 14, a feeding support 10 is fixed. On the feeding support 10, a plurality of feeding telescopic cylinders 9 perpendicular to and horizontally arranged with the conveying assembly 6 are fixed. The output end of the feeding telescopic cylinder 9 is detachably and fixedly connected to the feeding push plate 11. The feeding push plate 11 is arranged with a gap from the upper surface of the conveying assembly 6, and the feeding push plate 11 is also perpendicular to the feeding telescopic cylinder 9. By driving the feeding push plate 11 to move through the feeding telescopic cylinder 9, a plurality of products 5 to be processed on the conveying assembly 6 can be pushed onto the pushing shaft 4. It is set that the feeding push plate 11 is detachable, which is beneficial for the feeding push plate 11 to push and position the corresponding number of products 5 to be processed with the positioning plate 3 onto the pushing shaft 4, which is stable and reliable.

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

For the application of the laser engraving heads 32, conventional technologies can be adopted without limitation.

[0053] During application, the laser engraving translation telescopic cylinder 28 and the laser engraving lifting telescopic cylinder 29 can be used to translate and lift the laser engraving heads 32 respectively. With the position adjustment of the positioning plate 3, combined adjustment in the X, Y, and Z directions can be achieved, which can meet the laser engraving requirements of products 5 to be processed with different sizes, and is flexible and reliable.
