Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present application.

[0038] The present application provides an automatic loading and unloading device. Referring to Figures 1 to 6 , the automatic loading and unloading device includes: a processing platform 10 for mounting a workpiece; a transfer platform 20 spaced apart from the processing platform 10 along a first direction for transferring the workpiece; a first material taking mechanism 30 for transferring the workpiece to be processed on the transfer platform 20 to the processing platform 10, and transferring the processed workpiece on the processing platform 10 to the transfer platform 20; the first material taking mechanism 30 includes a first driving component 31 with a driving direction along the first direction, and a pair of first material taking components 32 drivingly connected to the first driving component 31; one of the first material taking components 32 is used for grasping the workpiece to be processed, and the other first material taking component 32 is used for grasping the processed workpiece.

[0039] In the embodiment of the present application, one of the first material taking components 32 can grasp the workpiece to be processed on the transfer platform 20, and the first driving component 31 drives the first material taking component 32 to move above the processing platform 10. Then, the other first material taking component 32 grasps the processed workpiece on the processing platform 10, and then places the unprocessed workpiece on the processing platform 10. In this way, the waiting time for loading and unloading can be reduced, and the efficiency can be improved.

[0040] Next, the first driving component 31 can drive the first material taking component 32 to return above the transfer platform 20, so that the empty first material taking component 32 grasps the workpiece to be processed on the transfer platform 20, and then places the processed workpiece back on the transfer platform 20, realizing the switching of workpieces in different states on the transfer platform 20. The workpiece to be processed is then driven by the first driving component 31 and transported to the processing platform 10. By the cooperation of the two first material taking components 32 and the transfer platform 20, the loading and unloading time can be reduced, and the efficiency can be improved.

[0041] In some embodiments, the above workpiece is generally a sheet-shaped workpiece. The first material taking component 32 can adopt the method of clamping with a cylinder or sucking with negative pressure. Specifically, it can clamp the edges at both ends of the workpiece or suck one side surface of the workpiece. In addition, referring to Figure 3 and Figure 5 , the above transfer platform 20 and processing platform 10 can adopt the method of clamping and fixing to fix and limit the workpiece. Specifically, the transfer platform 20 includes a receiving member 21. A limiting protrusion 22 is respectively arranged at two adjacent sides of the receiving member 21. First clamping members 23 are respectively arranged at the other two adjacent sides of the receiving member 21. The two first clamping members 23 are respectively driven by a first cylinder 24, so that the first clamping members 23 and the limiting protrusions 22 can jointly clamp the workpiece, and the workpiece is completely fixed in the first direction and the second direction. The processing platform 10 includes a receiving plate (not shown in the figure). A convex block is respectively arranged at two adjacent sides of the receiving plate. Second clamping members are respectively arranged at the other two adjacent sides of the receiving plate. The two second clamping members are respectively driven by a second cylinder, so that the second clamping members and the convex blocks can jointly clamp the workpiece, and the workpiece is completely fixed in the first direction and the second direction.

[0042] Further referring to Figure 2, the first material taking mechanism 30 further includes two first lifting components 34 connecting the first driving component 31 and the first material taking component 32, and the first lifting components 34 are arranged in one-to-one correspondence with the first material taking component 32; the first material taking component 32 is arranged along a second direction, and the second direction is perpendicular to the first direction. In this embodiment, the first lifting component 34 can adopt a lifting cylinder, and the first material taking component 32 can adopt a clamping jaw cylinder, and the clamping jaw cylinder includes a clamping jaw 33 for clamping the workpiece. The lifting cylinder drives the first material taking component 32 to descend to grab the workpiece, or places the workpiece on the transfer platform 20 or the processing platform 10, and then drives the first material taking component 32 to rise to move the workpiece away from the transfer platform 20 or the processing platform 10. One clamping jaw cylinder is correspondingly arranged on one lifting cylinder, and the cylinder body of the lifting cylinder is arranged at the driving end of the first driving component 31. The first driving component 31 can be an electric cylinder, which can drive the first lifting component 34 and the first material taking component 32 to move along the first direction, so that the first lifting component 34 and the first material taking component 32 move above the processing platform 10 or above the transfer platform 20, so as to complete the workpiece transfer on the two platforms.

[0043] Further referring to Figure 2 and Figure 3 , since the first material taking component 32 is arranged along the second direction, a driving cylinder (not shown in the figure) with a driving direction along the second direction can be arranged between the lifting cylinder and the first driving component 31, so that the two first material taking components 32 can correspond to the lower transfer platform 20 or the processing platform 10 in the second direction under the driving of the driving cylinder. Of course, a second driving component 26 can also be arranged below the transfer platform 20, and the driving direction of the second driving component 26 is along the second direction, which is used to drive the transfer platform 20 to be docked with the two first material taking components 32 respectively, and the second driving component 26 can also be a driving cylinder.

[0044] Referring to Figure 1 , the automatic loading and unloading device further includes: a material box 60, which is arranged on the side of the transfer platform 20 away from the processing platform 10; a second material taking mechanism 40, which is arranged along the second direction with the material box 60 and is located on one side of the transfer platform 20, and is used to transfer the workpiece to be processed to the transfer platform 20. In this embodiment, at least two material boxes 60 can be provided, one for placing the workpiece to be processed and one for placing the processed workpiece. The second material taking mechanism 40 can be a manipulator with a suction cup or a clamping jaw cylinder at the execution end. The manipulator can be composed of a three-axis linear drive module. The manipulator can also be a flexible manipulator composed of multiple electric motors.

[0045] In addition, a slot arranged vertically is provided in the material box 60, and the slot is used to accommodate the workpiece arranged vertically. Further referring to Figure 4, the second workpiece picking mechanism 40 further includes a second picking component 41 for picking up workpieces, and a flipping component 43 for driving the second picking component 41 to flip. In this embodiment, a rotary cylinder can also be provided at the execution end of the manipulator as the flipping component 43, and the second picking component 41 is arranged at the rotating end of the rotary cylinder. The clamping of the cylinder or the adsorption of the suction cup can be adopted. Specifically, a third cylinder can be arranged at the rotating end of the rotary cylinder. One side of the cylinder body of the third cylinder is arranged at the rotating end of the rotary cylinder, and a limiting member 44 is arranged on the other side of the cylinder body. A hook 42 is arranged at the driving end of the third cylinder, and the hook 42 can move towards the limiting member 44, and the two can be used to clamp the workpiece. The rotary cylinder drives the third cylinder to rotate, making the hook 42 vertically downward, which is convenient for picking up the workpiece in the material box 60 or putting the workpiece back into the material box 60. Of course, when the hook 42 picks up the workpiece in the material box 60, the rotary cylinder then drives the third cylinder to rotate, keeping the workpiece horizontal so as to place the workpiece on the transfer platform 20.

[0046] In some embodiments, referring to Figure 1 , the automatic loading and unloading device further includes: a cleaning component 51, arranged on one side of the second workpiece picking mechanism 40; a third driving component 52, arranged below the cleaning component 51 and the second workpiece picking mechanism 40; a carrier 53, arranged at the driving end of the third driving component 52; the second workpiece picking mechanism 40 is also used to transfer the processed workpiece on the transfer platform to the carrier 53, and the third driving component 52 is used to transfer the carrier 53 to the cleaning component 51. The cleaning component 51 in this embodiment can adopt the method of cleaning with a cleaning roller or negative pressure cleaning. Specifically, the cleaning component 51 includes a suction hood. The upper end of the suction hood is connected to an external negative pressure generator through a trachea, and the lower end faces one end of the third driving component 52. The third driving component 52 can be an electric cylinder, and an installation position for placing the workpiece is arranged on the carrier 53. The processed workpiece on the transfer platform can be taken off by the second workpiece picking mechanism 40 and placed on the carrier 53. The third driving component 52 drives the carrier 53 and the workpiece to move to the cleaning component 51, and the cleaning component 51 removes the residues generated during the processing of the workpiece. After cleaning, the third driving component 52 transfers the workpiece to the second workpiece picking mechanism 40, and the second workpiece picking mechanism 40 puts the workpiece back into the material box 60. Further, the above-mentioned cleaning component 51, the second workpiece picking mechanism 40, and the material box 60 are arranged in sequence along the second direction, and the driving direction of the third driving component 52 is along the second direction. Such an arrangement can shorten the transfer path of the workpiece and further improve the transfer efficiency.

Further, the laser processing device further includes a laser processing module 13 disposed on the processing platform 10 and a fourth driving component 12 for driving the movement of the processing platform 10. The laser processing module 13 includes at least one processing head, and the processing head is disposed on a gantry, and the gantry is disposed on the machine table 11. The processing head is vertically downward and faces the processing platform 10 below. The fourth driving component 12 can drive the processing platform 10 to move along a first direction and a second direction, so that the processing head can form a corresponding processing trajectory on the workpiece. Of course, the fourth driving component 12 can also drive the processing platform 10 to lift, ensuring that the laser beam emitted by the processing head can be focused on the workpiece. In addition, the laser processing device further includes a blowing component 14 disposed on one side of the processing head. The blowing component 14 includes an annular air nozzle, and an air flow channel is provided inside the air nozzle. Air holes can be provided at the upper end and the lower end of the air nozzle for blowing air to the processing head and the processing platform 10 to remove the dust on the workpiece and avoid the dust from entering the optical path above.

By doubling the number of the above-mentioned processing heads, processing platforms 10, transfer platforms 20 and first material taking components 32, the laser processing device can perform the loading, unloading, transfer and processing of multiple workpieces at the same time, further improving the processing efficiency.

[0049] In the embodiment of the present application, the working principle of the automatic loading and unloading device is as follows: one of the first material taking components 32 grabs the workpiece to be processed on the transfer platform 20, and the first driving component 31 drives the first material taking component 32 to move above the processing platform 10, and the other first material taking component 32 grabs the processed workpiece on the processing platform 10, and then places the unprocessed workpiece on the processing platform 10. Then, the first driving component 31 can drive the first material taking component 32 to return above the transfer platform 20, so that the empty first material taking component 32 grabs the workpiece to be processed on the transfer platform 20, and then places the processed workpiece back on the transfer platform 20, realizing the switching of workpieces in different states on the transfer platform 20. The workpiece to be processed is driven by the first driving component 31 and transferred to the processing platform 10.
