[0034] Reference Figure 3 and Figure 4In order to prevent too much pallet from piling up and squeezing into the docking position of the loading conveyor belt 1, a loading baffle 331 and a position on the partition 33 relative to the manipulator 8 are respectively provided with a loading diversion driving source, which is specifically a loading diversion cylinder 34. The output end of the loading diversion cylinder 34 is provided with a loading diversion plate 341 for side-pushing the pallet to position.

When the material unloading diversion cylinder 35 on the material unloading baffle 332 drives the material unloading diversion plate 351 to operate, the material unloading diversion plate 351 can push the pallet from the other side, so that the pallet is clamped between the material unloading diversion plate 351 and the partition 33. All the loading diversion cylinders 34 and all the unloading diversion cylinders 35 are staggered, and a plurality of photoelectric elements 36 are provided on the partition 33.

[0035] Reference Figures 1 to 6 The working principle of the fully automatic anti-mixing laser processing automatic line of the present invention is:

[0036] The feeding motor 11 controls the feeding drive belt 12 to run, thereby driving the feeding conveying belt 1 to run, and the unloading motor 21 controls the unloading drive belt 22 to run, thereby driving the unloading conveying belt 2 to run in the opposite direction relative to the feeding conveying belt 1;

[0037] The operator places a plurality of pallets with different material information on the feeding conveyor belt 1 in sequence at the head of the rack 3, and the feeding conveyor belt 1 conveys the plurality of pallets with different material information forward;

[0038] When the photoelectric element 36 senses that the pallet has entered the code reading space between the support frame 5 and the feeding conveyor belt 1, the material blocking cylinder 61 drives the material blocking member 62 to move downward to block the pallet in the code reading space, and the code reader 51 quickly reads the material information on the pallet;

[0039] If the material information of the tray is different from the product information to be lasered by the laser machine 81 of the workstation, the material stopper 62 is reset, and the tray continues to move forward with the feeding conveyor belt 1 to the next workstation for code reading;

[0040] If the material information of the pallet is consistent with the product information to be lasered by the laser machine 81 of the workstation, the lifting cylinder 73 controls the side push block 74 to move down to the side of the pallet, and the side push cylinder 71 pulls the connecting plate 72 to slide along the two guide rods 721. The connecting plate 72 drives the lifting cylinder 73 and the side push block 74 to move together, and the side push block 74 can push the pallet from the feeding conveyor belt 1 to the storage conveyor belt 4;

[0041] The storage motor 42 controls the storage conveyor belt 4 to run through the gearbox, so that the tray is away from the support frame 5 and is temporarily stored on the storage conveyor belt 4;

[0042] The robot 8 of the workstation grabs the pallet stored on the material storage conveyor belt 4 and places the pallet on the laser machine 81 of the workstation for laser processing;

[0043] After the laser processing is completed, the robot 8 of the workstation grabs the pallet carrying the processed products and places the pallet on the unloading conveyor belt 2. The unloading conveyor belt 2 returns the pallet carrying the processed products to the original operator, who can then remove the pallet carrying the products from the unloading conveyor belt 2.

[0044] In the fully automatic anti-mixing laser processing line of the present invention, each pallet is designed with a different QR code, each workstation is designed with a code reading function, and a variety of different photosensitive elements are used for precise diversion and positioning. The workstations can be increased or decreased according to site and production capacity requirements, and can also be freely allocated on the control system according to the needs of processing workpieces.

[0045] The fully automatic anti-mixing laser processing line of the present invention uniformly conveys multiple pallets carrying multiple products through the feeding conveyor belt 1, uses the material blocking mechanism 6 to block the pallet to prevent the pallet from being transported out of the docking position, and the code reader 51 reads the material information on the pallet. The side pushing mechanism 7 pushes the pallet sideways to the storage conveyor belt 4 and the storage conveyor belt 4 transports the storage material, and then accurately transfers it to the laser machine 81 for laser processing. The entire equipment can accurately identify, store and laser process multiple pallets with different material information conveyed on the same feeding conveyor belt 1, so that the same production line can laser process multiple products at the same time, avoid mixing of materials, and help improve production efficiency and customer satisfaction.

[0046] The above disclosure is only a preferred embodiment of the present invention, which cannot be used to limit the scope of protection of the present invention. Therefore, equivalent changes made within the scope of the patent application of the present invention are still within the scope covered by the present invention.
