[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 system has a problem of low production efficiency.

[0038] The present utility model proposes a laser processing system for use in photovoltaic wafer processing to solve the problem that the existing laser processing system has low productivity 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 700 (Direct Drive Motor), the DD motor 700 is drivingly connected to the turntable 100 to drive 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 wafer. The turntable 100 is used for placing materials. After the materials are placed on the turntable 100, the DD motor 700 drives the turntable 100 to rotate, and the turntable 100 can drive the materials to rotate.

[0040] A first processing station 200, a first loading / unloading station 400, a second processing station 300, and a second loading / unloading station 500 are sequentially arranged around the rotation axis of the turntable 100. The turntable 100 can synchronously transfer the materials at the first processing station 200 and the second processing station 300 to the first loading / unloading station 400 and the second loading / unloading station 500. Specifically, the material at the first processing station 200 can be transferred to the first loading / unloading station 400 or the second loading / unloading station 500 according to the rotation direction of the turntable 100, and the material at the second processing station 300 can be transferred to the first loading / unloading station or the second loading / unloading station 500 according to the rotation direction of the turntable 100; when the material at the first processing station 200 is transferred to the first loading / unloading station 400, the material at the second processing station 300 is transferred to the second loading / unloading station 500; the turntable 100 can also synchronously transfer the materials at the first loading / unloading station 400 and the second loading / unloading station 500 to the first processing station 200 and the second processing station 300. Similarly, the material at the first loading / unloading station 400 can be transferred to the first processing station 200 or the second processing station 300 according to the rotation direction of the turntable 100, and the material at the second loading / unloading station 500 can be transferred to the first processing station 200 or the second processing station 300 according to the rotation direction of the turntable 100; when the material at the first loading / unloading station 400 is transferred to the first processing station 200, the material at the second loading / unloading station 500 is transferred to the second processing station 300.

[0041] A conveyor line mechanism 600 has a first transportation track and a second transportation track to enable part of the materials to move in the laser processing system along the first transportation track and another part of the materials to move along the second transportation track. The first loading / unloading station 400 is arranged in the first transportation track, and the second loading / unloading station 500 is arranged in the second transportation track. The conveyor line mechanism 600 can also input materials into the turntable 100 or receive the materials output from the turntable 100. Specifically, when the conveyor line mechanism 600 is transporting materials at this time, the materials in the first transportation track can be input into the turntable 100 through the first loading / unloading station 400, and the materials in the second transportation track can be input into the turntable 100 through the second loading / unloading station 500, so that the conveyor line mechanism 600 of the present application can input two materials into the turntable 100 at the same time, shortening the time for the materials to be input into the turntable 100, improving the efficiency, and thus increasing the production capacity. Then the turntable 100 drives the materials to rotate and rotates the materials from the loading / unloading station to the processing station for processing. At this time, the laser processing system of the present application can process two materials through a certain processing time, thereby increasing the output of the laser processing system and solving the technical problem of low production efficiency in the prior art. Further, when the materials at the two processing stations are processed, the turntable 100 rotates to transfer the materials from the processing station to the loading / unloading station. At this time, the conveyor line mechanism 600 receives the processed materials in the first loading / unloading station 400 and the second loading / unloading station 500, so that the processed materials move in the laser processing system.

[0042] In one embodiment, referring to Figure 1 , the turntable 100 includes a disk body 110 and carriers 120 for placing materials. The number of the carriers 120 is configured to be four, and the four carriers 120 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 120 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 700 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 700, the angle of each drive rotation is the same. Further, in the present application, the DD motor 700 is drivingly connected to the disk body 110. When the DD motor 700 drives the disk body 110 to rotate, the disk body 110 can drive the carriers 120 to rotate. However, this design is not limited thereto. In other embodiments, the number of the carriers 120 can be set to six, eight, etc. When the number of the carriers 120 is the sum of multiple processing positions and loading / unloading positions, the laser processing system can form a waiting material position, and the waiting material position can enable the turntable 100 to have the function of temporarily storing materials.

[0043] In one embodiment, referring to Figure 1 , the conveyor line mechanism 600 includes a first conveyor line mechanism 610 and a second conveyor line mechanism 620. The first conveyor line mechanism 610 enables part of the materials to move in the laser processing system along the first transportation track, and can input materials to the turntable 100 through the first loading / unloading position 400, or receive the materials output from the turntable 100 through the first loading / unloading position 400; the second conveyor line mechanism 620 enables another part of the materials to move in the laser processing system along the second transportation track, and can input materials to the turntable 100 through the second loading / unloading position 500, or receive the materials output from the turntable 100 through the second loading / unloading position 500. Specifically, the conveyor line mechanism 600 is set to two. Among them, the first conveyor line mechanism 610 corresponds to the first transportation track, and the second conveyor line mechanism 620 corresponds to the second transportation track. In this way, when one of the conveyor line mechanisms 600 needs to be maintained during the use of the conveyor line mechanism 600 of the present application, 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 and prevent the production line from stopping, and further improve the production capacity of the laser processing system of the present application during the maintenance of some structures during use.

[0044] Further, since the first loading and unloading position 400 is set in the first transportation track and the second loading and unloading position 500 is set in the second transportation track, part of the structure of the turntable 100 can coincide with the first conveyor line mechanism 610 and the second conveyor line mechanism 620. At this time, when the conveying directions of the first conveyor line mechanism 610 and the second conveyor line mechanism 620 are parallel, the one that can make the distance between the first conveyor line mechanism 610 and the second conveyor line mechanism 620 smaller makes the structure of the present application more compact.

[0045] In one embodiment, referring to Figure 1 , Figure 2 , the first conveyor line mechanism 610 includes a first loading conveyor line 611, a first unloading conveyor line 612 and a first transfer structure 613. The first loading and unloading position 400 is arranged between the first loading conveyor line 611 and the first unloading conveyor line 612. The first transfer structure 613 is used to transfer the material in the first loading conveyor line 611 to the first loading and unloading position 400, or transfer the material at the first loading and unloading position 400 to the first unloading conveyor line 612. Specifically, during use, when the first loading conveyor line 611 conveys the unprocessed material to a preset position, the first transfer structure 613 transfers the unprocessed material in the first loading conveyor line 611 to the first loading and unloading position 400 and places the material on the carrier 120 of the turntable 100. After the material is on the turntable 100, the DD motor 700 drives the turntable 100 to rotate, so that the material at the first loading and unloading position 400 rotates to the first processing position 200 or the second processing position 300. At this time, the laser processes the material. After the material is processed, the DD motor 700 drives the turntable 100 to rotate, so that the processed material rotates to the first loading and unloading position 400, and it is transferred to the first unloading conveyor line 612 through the first transfer structure 613.

[0046] In one embodiment, referring to Figure 2, the first transfer structure 613 includes a first guide rail 6131, a first driving member 6132, and a first suction cup 6133. The first driving member 6132 and the first suction cup 6133 are both installed on the first guide rail 6131. The first driving member 6132 is drivingly connected to the first suction cup 6133. The first driving member 6132 drives the first suction cup 6133, enabling the first suction cup 6133 to move along a first transportation trajectory. Further, the extending direction of the first guide rail 6131 is parallel to the direction of the first transportation trajectory. At the same time, since the first transportation trajectory corresponds to the first conveying line mechanism 610 and the first loading and unloading position 400 is set in the first transportation trajectory, when the first driving member 6132 drives the first suction cup 6133 to move along the first transportation trajectory, the first suction cup 6133 can transfer the material in the first feeding conveyor line 611 to the first feeding position, or transfer the material at the first loading and unloading position 400 to the first discharging conveyor line 612.

[0047] Further, in this embodiment, referring to Figure 2 , the first driving member 6132 includes a first driving motor 6132a and a synchronous belt (not shown). The first driving motor 6132a is drivingly connected to the synchronous belt. The synchronous belt is installed on the first guide rail 6131. The first suction cup 6133 is slidably engaged with the first guide rail 6131. The synchronous belt is drivingly connected to the first suction cup 6133. When the first driving motor 6132a drives the synchronous belt to rotate, the synchronous belt can drive the first suction cup 6133 to move, causing the first suction cup 6133 to slide along the first guide rail 6131. Further, the synchronous belt and the first suction cup 6133 are connected by screwing. In this way, the synchronous belt can drive the first suction cup 6133 to move during rotation.

[0048] In one embodiment, referring to Figure 2, the first suction cups 6133 are configured to be two, and the first driving member 6132 is drivingly connected to the two first suction cups 6133 so that the two first suction cups 6133 can move synchronously. That is to say, the above-mentioned synchronous belt is drivingly connected to the two first suction cups 6133. When the first driving motor 6132a drives the synchronous belt to rotate, the synchronous belt can synchronously drive the two first suction cups 6133 to move along the first guide rail 6131; the first loading conveyor line 611 has a first loading position 6111 disposed close to the first loading and unloading position 400. When the material is located at the first loading position 6111, the first suction cups 6133 in the first transfer structure 613 can grab the material from the first loading conveyor line 611. Then, the first driving member 6132 drives the first suction cups 6133 to move, and the first suction cups 6133 can transfer the material to the first loading and unloading position 400. The first unloading conveyor line 612 has a first receiving position 6121 disposed close to the first loading and unloading position 400. The first suction cups 6133 in the first transfer structure 613 can place the material in the first unloading conveyor line 612; the distance between the first loading position 6111 and the first loading and unloading position 400, the distance between the first receiving position 6121 and the first loading and unloading position 400, and the distance between the two first suction cups 6133 are all the same. Specifically, when one of the first suction cups 6133 corresponds to the first loading position 6111, the other suction cup can correspond to the first loading and unloading position 400. At this time, when the first driving member 6132 drives the two first suction cups 6133 to move, one of the first suction cups 6133 can grab the material located at the first loading position 6111, and the other first suction cup 6133 can grab the material located at the first loading and unloading position 400. At this time, when the first transfer structure 613 is driven once, the movement of the two materials can be achieved, that is, the material located at the first loading position 6111 is transferred to the first loading and unloading position 400, and the material located at the first loading and unloading position 400 is transferred to the first receiving position 6121. In this way, the operation of the first transfer structure 613 can be reduced at this time, the working efficiency of the transfer structure can be improved, and further the working efficiency of the laser processing system can be improved, thereby improving the production capacity.

[0049] In one embodiment, refer to Figure 1, the second conveyor line mechanism 620 includes a second loading conveyor line 621, a second unloading conveyor line 622, and a second transfer structure 623. The second loading and unloading position 500 is disposed between the second loading conveyor line 621 and the second unloading conveyor line 622. The second transfer structure 623 is used to transfer the materials in the second loading conveyor line 621 to the second loading and unloading position 500, or transfer the materials at the second loading and unloading position 500 to the second unloading conveyor line 622. Specifically, during use, when the second loading conveyor line 621 conveys the unprocessed materials to a preset position, at this time, the second transfer structure 623 transfers the unprocessed materials in the second loading conveyor line 621 to the second loading and unloading position 500, and makes the materials located on the carrier 120 of the turntable 100. After the materials are located on the turntable 100, the DD motor 700 drives the turntable 100 to rotate, so that the materials at the second loading and unloading position 500 are rotated to the first processing position 200 or the second processing position 300. At this time, the laser processes the materials. When the materials are processed, the DD motor 700 drives the turntable 100 to rotate, so that the processed materials are rotated to the second loading and unloading position 500, and are transferred to the second unloading conveyor line 622 through the second transfer structure 623. Further, when the second conveyor line mechanism 620 in this embodiment cooperates with the first conveyor line mechanism 610 in the above embodiment, materials can be synchronously input into the turntable 100. That is to say, the first transfer structure 613 transfers the materials in the first loading conveyor line 611 to the first loading and unloading position 400, so that the materials are located on one of the carriers 120. The second transfer structure 623 transfers the materials in the second loading conveyor line 621 to the second loading and unloading position 500, so that the materials are located on one of the carriers 120. Then, the DD motor 700 drives the turntable 100 to rotate, and transfers the materials from the loading and unloading position to the processing position. At this time, the laser processes the materials at the two processing positions. When the processing is completed, according to the rotation direction of the DD motor 700, the materials entering the turntable 100 through the first loading and unloading position 400 can be output through the second loading and unloading position 500, or output through the first loading and unloading position 400. Then, the first transfer structure 613 and the second transfer structure 623 transfer the materials at the first loading and unloading position 400 and the second loading and unloading position 500 to the first unloading conveyor line 612 and the second unloading conveyor line 622.

[0050] In one embodiment, the second transfer structure 623 includes a second guide rail, a second driving member, and a second suction cup. The second driving member and the second suction cup are both installed on the second guide rail. The second driving member is drivingly connected to the second suction cup. The second driving member drives the second suction cup, and can make the second suction cup move along the second transportation trajectory. In this embodiment, the structure of the second driving member is the same as the structure of the above first driving member 6132 (see Figure 1 , Figure 2 ), and will not be specifically described herein.

[0051] In one embodiment, two second suction cups are provided, and the second driving member is drivingly connected to the two second suction cups so that the two second suction cups can move synchronously; the second loading conveyor line 621 has a second loading position 6211 disposed near the second loading and unloading position 500, and the second unloading conveyor line 622 has a second receiving position 6221 disposed near the second loading and unloading position 500. The distance between the second loading position 6211 and the second loading and unloading position 500, the distance between the second receiving position 6221 and the second loading and unloading position 500, and the distance between the two second suction cups are all the same. Further, when two second suction cups are provided in the second transfer structure 623, its structure is the same as that when two first suction cups 6133 are provided in the first transfer structure 613 (see Figure 1 , Figure 2 ), and the embodiments regarding two second suction cups provided in the second transfer structure 623 will not be described in detail herein.

Further, when the conveying directions of the first conveyor line mechanism 610 and the second conveyor line mechanism 620 are parallel, the structure of the laser processing system of the present application is more compact and occupies a smaller area compared to the structure where the first conveyor line mechanism 610 and the second conveyor line mechanism 620 are not parallel; at the same time, when the conveying directions are parallel, the conveying directions of the materials can be the same or opposite.

[0053] In one embodiment, referring to Figure 2 , the first loading conveyor line 611, the second loading conveyor line 621, the first unloading conveyor line 612, and the second unloading conveyor line 622 of the present application all adopt a belt conveying module 800. Specifically, the belt conveying module 800 includes a mounting frame 810, a conveyor belt 820 mounted on the mounting frame 810, and a second driving motor 830. The second driving motor 830 is drivingly connected to the conveyor belt 820, and the conveyor belt 820 is driven to rotate by the second driving motor 830, so as to convey the material by the conveyor belt 820.
