[0037] When producing photovoltaic wafers, laser processing is required. When different types of photovoltaic wafers are laser processed, there is a problem that the processing time of some photovoltaic wafers is relatively long. For photovoltaic wafers with a relatively long single processing time, the existing laser processing systems have low production efficiency.
[0038] The present utility model provides a laser processing system for processing photovoltaic wafers, which solves the problem of low production capacity of the existing laser processing systems for photovoltaic wafers with a relatively long single processing time.
[0039] Please refer to Figure 1 , Figure 2 , in an embodiment of the present utility model, the laser processing system includes: a turntable 100 and a DD motor 800 (Direct Drive Motor), the DD motor 800 is drivingly connected to the turntable 100 for driving the turntable 100 to rotate. The laser processing system further includes a laser (not shown), and the laser emits laser light to process the photovoltaic wafers. Further, the turntable 100 is used for placing materials. After the materials are placed on the turntable 100, the DD motor drives the turntable 100 to rotate, and the turntable 100 can drive the materials to rotate.
[0040] A first processing position 200, a first loading / unloading position 400, a second processing position 300, and a second loading / unloading position 500 are sequentially arranged around the rotation axis of the turntable 100. The turntable 100 can synchronously transfer the materials at the first processing position 200 and the second processing position 300 to the first loading / unloading position 400 and the second loading / unloading position 500. Specifically, the materials at the first processing position 200 can be transferred to the first loading / unloading position 400 or the second loading / unloading position 500 according to the rotation direction of the turntable 100, and the materials at the second processing position 300 can be transferred to the first loading / unloading position or the second loading / unloading position 500 according to the rotation direction of the turntable 100; when the materials at the first processing position 200 are transferred to the first loading / unloading position 400, the materials at the second processing position 300 are transferred to the second loading / unloading position 500; further, the turntable 100 can also synchronously transfer the materials at the first loading / unloading position 400 and the second loading / unloading position 500 to the first processing position 200 and the second processing position 300. Similarly, the materials at the first loading / unloading position 400 can be transferred to the first processing position 200 or the second processing position 300 according to the rotation direction of the turntable 100, and the materials at the second loading / unloading position 500 can be transferred to the first processing position 200 or the second processing position 300 according to the rotation direction of the turntable 100; when the materials at the first loading / unloading position 400 are transferred to the first processing position 200, the materials at the second loading / unloading position 500 are transferred to the second processing position 300.
[0041] The conveyor line mechanism 600 is used to transport materials, enabling the materials to move within the laser processing system and capable of inputting materials into the turntable 100 or receiving the materials output from the turntable 100. Specifically, the conveyor line mechanism 600 inputs materials into the turntable 100 through the first loading and unloading position 400 and the second loading and unloading position 500, or receives the materials output from the turntable 100 through the first loading and unloading position 400 and the second loading and unloading position 500. In this embodiment, after the conveyor line mechanism 600 inputs materials into the turntable 100 through the first loading and unloading position 400 and the second loading and unloading position 500, then the turntable 100 drives the materials located at the first loading and unloading position 400 and the second loading and unloading position 500 to rotate to the first processing position 200 and the second processing position 300. Then the materials located at the first processing position 200 and the second processing position 300 can be processed by the laser in the laser processing system. During the processing, the laser processing system of the present application can process two materials. When the processing is completed, the turntable 100 rotates to transfer the processed materials from the first processing position 200 and the second processing position 300 to the first loading and unloading position 400 and the second loading and unloading position 500. At this time, the conveyor line mechanism 600 receives the processed materials through the first loading and unloading position 400 and the second loading and unloading position 500. At this time, two processed products can be obtained. In this way, within a certain processing time, the present application can obtain more products, which can improve the production capacity of the laser processing system of the present application and solve the problem of low production efficiency in the prior art.
[0042] However, this design is not limited thereto. In other embodiments, the present application can also be provided with a third processing position and a third loading and unloading position. At this time, during processing, the conveyor line mechanism 600 can input materials into the turntable 100 through the first loading and unloading position 400, the second loading and unloading position 500, and the third loading and unloading position, so that the materials are located on the turntable 100. Then when the turntable 100 drives the materials to rotate, the first processing position 200, the second processing position 300, and the third processing position are reached. At this time, the laser in the processing system processes the materials, enabling three materials to be processed simultaneously.
[0043] In one embodiment, refer to Figure 1, the turntable 100 includes a disk body 110 and carriers (not shown), the carriers are used for placing materials, the number of the carriers is configured to be four, and the four carriers are evenly distributed along the rotation circumference of the disk body 110. The first processing position 200, the first loading / unloading position 400, the second processing position 300, the second loading / unloading position 500 and the four carriers are arranged in one-to-one correspondence. Specifically, the central angle between adjacent two positions (loading / unloading position, processing position) is 90 degrees. In this way, the angle that the DD motor drives the turntable 100 to rotate each time is the same. That is to say, regardless of the forward or reverse rotation direction of the DD motor, the angle driven to rotate each time is the same. Further, in the present application, the DD motor is drivingly connected to the disk body 110. When the DD motor drives the disk body 110 to rotate, the disk body 110 can drive the carriers to rotate. However, this design is not limited thereto. In other embodiments, the number of carriers can be set to six, eight, etc. When the number of carriers is the sum of multiple processing positions and loading / unloading positions, the laser processing system can form waiting positions for materials at this time, and the waiting positions can enable the turntable 100 to have the function of temporarily storing materials.

Specifically, the conveyor line mechanism 600 is set to two, and respectively inputs materials to the turntable 100 through the first loading / unloading position 400 and the second loading / unloading position 500, or receives the materials output by the turntable 100. During use, when one of the conveyor line mechanisms 600 needs to be maintained, the other conveyor line mechanism 600 can work normally, so as to ensure the normal operation of the laser processing system of the present application without stopping the line, and further improve the production capacity of the laser processing system of the present application when encountering maintenance during use.

Specifically, the materials are conveyed by the first loading conveyor line 611 to be close to the first transfer structure 613. At this time, the first transfer structure 613 transfers the materials in the first loading conveyor line 611. The first transfer structure 613 is driven for the first time, and the materials are transferred through the first loading and unloading position 400 to the carrier at the first loading and unloading position 400 on the turntable 100. When the materials at the processing position are processed, at this time, the DD motor drives the turntable body 110 to rotate, so that the unprocessed materials enter the first processing position 200 from the first loading and unloading position 400. At this time, the materials processed at the second processing position 300 enter the first loading and unloading position 400.

That is to say, the first transfer structure 613 is arranged between the first feeding conveyor line 611 and the first discharging conveyor line 612; when the first driving member 6132 drives the first swing arm 6131 to rotate, one of the first suction cups 6133 can transfer the material in the first feeding conveyor line 611 to the first loading and unloading position 400, and at the same time, the other first suction cup 6133 transfers the material at the first loading and unloading position 400 to the first discharging conveyor line 612.

That is to say, after the material processing is completed, one of the first suction cups 6133 is arranged corresponding to the first feeding conveyor line 611, and the other first suction cup 6133 is arranged corresponding to the first loading and unloading position 400. At this time, the two first suction cups 6133 work simultaneously.

The first transfer structure 613 rotates ninety degrees, and the processed material can be located on the first discharging conveyor line 612, and the unprocessed material enters the first loading and unloading position 400. In this way, the first driving member 6132 can drive once to realize the transfer of two materials, which can improve the transfer efficiency of the materials, and further improve the production efficiency of the present application, and further solve the technical problems existing in the prior art.
[0048] In one embodiment, refer to Figure 1, the second conveying line mechanism 620 can adopt the following structure.

Specifically, the materials are conveyed by the second loading conveying line 621 to be close to the second transfer structure 623. At this time, the second transfer structure 623 transfers the materials in the second loading conveying line 621. The second transfer structure 623 is driven for the first time, and transfers the materials to the carrier at the second loading and unloading position 500 in the turntable 100 through the second loading and unloading position 500. When the materials at the processing position are processed, at this time, the DD motor drives the disk body 110 to rotate, so that the unprocessed materials enter the second processing position 300 from the second loading and unloading position 500.
