In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0044] like Figure 1 and Figure 2 As shown, this embodiment provides a laser sintering device, which includes an assembly line transmission module 1, a rotating transport module 2 and a rotating platform 3, wherein the assembly line transmission module 1 is used to transmit solar cells, the assembly line transmission module 1 and the rotating platform 3 are respectively located on two opposite sides of the rotating transport module 2, the rotating transport module 2 is used to drive the solar cells to rotate so as to transport the solar cells between the loading station 16 of the assembly line transmission module 1 and the unloading station of the rotating platform 3, and the rotating platform 3 is used to carry the solar cells to rotate between the processing station and the unloading station of the rotating platform 3.

[0045] In the laser sintering equipment provided in this embodiment, when the pipeline transmission module 1 transmits the solar cell to the loading station 16, the rotary transport module 2 rotates and transports the solar cell at the loading station 16 to the unloading station of the rotary carrier 3. Then, the rotary carrier 3 rotates the solar cell at the unloading station to the processing station to facilitate processing of the solar cell. After the solar cell at the processing station is processed, the rotary carrier 3 rotates the solar cell at the processing station to the unloading station, so that the rotary transport module 2 can rotate and transport the processed solar cell at the unloading station to the loading station 16 again. Under the joint cooperation of the pipeline transmission module 1, the rotary transport module 2 and the rotary carrier 3, the laser sintering equipment realizes the automatic loading of solar cells and the automatic unloading after processing, and realizes the conversion of solar cells between various stations by rotation, which not only makes the layout of each module more reasonable, but also improves the processing efficiency.

[0046] Optionally, in this embodiment, if Figure 1 and Figure 2 As shown, the pipeline transmission module 1 transmits the solar cell sheets along the left-right direction, and the pipeline transmission module 1 and the rotating platform 3 are respectively located on two opposite sides of the rotating transport module 2 along the front-back direction.

[0047] In this embodiment, if Figure 1 and Figure 2 As shown, the laser sintering equipment further includes a laser sintering module 4, which is located on a side of the rotating platform 3 away from the rotating transport module 2 (i.e., the laser sintering module 4 is located on the rear side of the rotating platform 3), and the laser sintering module 4 is used to laser sinter the solar cell at the processing station. Since the specific structure and working principle of the laser sintering module 4 belong to the prior art, they will not be described here.

[0048] In this embodiment, the laser sintering equipment also includes a material unloading module 5, and the pipeline transmission module 1 transmits the solar cell from left to right, so that the solar cell passes through the furnace connection station 11, the first positioning station 12, the waste recovery station 13, the drawer feeding station 14, the second positioning station 15, the loading station 16 and the unloading and picking station 17 on the pipeline transmission module 1 in sequence. When the solar cell is transmitted to the first positioning station 12, the positioning member (not shown in the figure) located at the first positioning station 12 can realize the positioning of the solar cell to ensure the accuracy of the placement of the solar cell on the pipeline transmission module 1. When the positioned solar cell is further transmitted to the waste recovery station 13, the waste transplanting module (not shown in the figure) at the waste recovery station 13 can pick up and unload unqualified solar cells, and replenish them. The material module (not shown in the figure) can replenish the required number of solar cells at the drawer replenishment station 14. When the replenished solar cells are transferred to the second positioning station 15, the positioning member (not shown in the figure) located at the second positioning station 15 can realize the positioning of the solar cells. When the positioned solar cells are further transported to the loading station 16, the rotary transport module 2 rotates and transports the solar cells at the loading station 16 to the unloading station of the rotary platform 3. When the rotary transport module 2 rotates and transports the processed solar cells at the unloading station to the loading station 16 again, the assembly line transmission module 1 continues to transport the solar cells until the solar cells are transported to the unloading pick-up station 17, so that the unloading module 5 can pick up and unload the processed solar cells at the unloading pick-up station 17. It should be noted that the laser sintering equipment meets the production demand of 9300pcs / s of solar cells through the above-mentioned processing flow of solar cells. It should be noted that since the unloading module 5, the positioning member, the waste material transplanting module and the material replenishing module all belong to the prior art, they will not be described in detail here.

[0049] Optionally, in this embodiment, the pipeline transmission module 1 can be a belt conveyor, and the pipeline transmission module 1 can be a whole belt conveyor. Optionally, in other embodiments, the pipeline transmission module 1 can also be a belt conveyor spliced ​​with multiple sections, so as to facilitate the repair and replacement of the belt conveyor with problems.

[0050] Combination Figure 3 The specific structure of the rotating transport module 2 is described as follows: Figure 3As shown, the rotary transport module 2 includes a first rotary drive component 21 and an adsorption component 22, wherein the adsorption component 22 is connected to the output end of the first rotary drive component 21 by transmission, the first rotary drive component 21 is used to drive the adsorption component 22 to rotate, and the adsorption component 22 is located above the assembly line transmission module 1 and the rotating platform 3, and the adsorption component 22 can adsorb the solar cells at the loading station 16 and the unloading station. It should be noted that the first rotary drive component 21 can be a rotary motor, and when the adsorption component 22 is located directly above the loading station 16, under the action of the suction force of the adsorption component 22, the solar cells at the loading station 16 can be sucked up by the adsorption component 22. Similarly, when the adsorption component 22 is located directly above the unloading station, under the action of the suction force of the adsorption component 22, the solar cells at the unloading station can be sucked up by the adsorption component 22. In this embodiment, the adsorption component 22 is used to adsorb and pick up the solar cells at the loading station 16 and the unloading station, thereby avoiding clamping damage to the solar cells and improving the protection of the solar cells.

[0051] Optionally, in this embodiment, the adsorption assembly 22 includes a mounting frame 221 and a plurality of adsorption plates 222, wherein the mounting frame 221 is transmission-connected to the output end of the first rotation drive assembly 21, and the plurality of adsorption plates 222 are connected to the mounting frame 221, and each adsorption plate 222 is capable of adsorbing solar cells at the loading station 16 and the unloading station, and when at least one adsorption plate 222 is located directly above the loading station 16, at least one adsorption plate 222 is located directly above the unloading station. The above arrangement ensures that when at least one adsorption plate 222 absorbs the solar cell at the loading station 16, at this time, at least one adsorption plate 222 absorbs the solar cell at the unloading station, and the mounting frame 221 synchronously drives multiple adsorption plates 222 to rotate 180°, the solar cell absorbed at the unloading station is moved by the corresponding adsorption plate 222 to directly above the loading station 16, and the solar cell absorbed at the loading station 16 is moved by the corresponding adsorption plate 222 to just above the unloading station, so that the mounting frame 221 can synchronously realize the transportation of the solar cell to be processed from the loading station 16 to the unloading station and the transportation of the processed solar cell from the unloading station to the loading station 16 in the process of driving the multiple adsorption plates 222 to rotate synchronously, thereby further improving the processing efficiency of the solar cell.

[0052] Optionally, in the present embodiment, the adsorption assembly 22 includes four adsorption plates 222, two loading stations 16 are provided on the assembly line transmission module 1, and two unloading stations are provided on the rotating platform 3. When two adsorption plates 222 are opposite to the two loading stations 16 one by one, the remaining two adsorption plates 222 are opposite to the two unloading stations one by one. The above arrangement enables the mounting frame 221 to synchronously realize the transportation of two solar cells to be processed from the loading station 16 to the unloading station and the transportation of two processed solar cells from the unloading station to the loading station 16 in the process of driving the multiple adsorption plates 222 to rotate synchronously, thereby further improving the processing efficiency of the solar cells. It should be noted that in other embodiments, the specific number of adsorption plates 222 can be set according to demand.

[0053] In this embodiment, the mounting frame 221 is a rectangular frame, and each corner of the rectangular frame is connected to a suction plate 222. By designing the mounting frame 221 as a rectangular frame structure, the structural strength and structural stability of the mounting frame 221 are effectively improved, and the rationality of the layout of the multiple suction plates 222 is also improved.

[0054] Combination Figure 4 The specific structure of the rotating stage 3 is described as follows. Figure 4 As shown, the rotating platform 3 includes a second rotating drive assembly 31 and a bearing assembly 32. The bearing assembly 32 is connected to the output end of the second rotating drive assembly 31. The second rotating drive assembly 31 is used to drive the bearing assembly 32 to rotate, and the bearing assembly 32 is used to carry the solar cell. It should be noted that the second rotating drive assembly 31 can be a rotating motor.

[0055] Alternatively, if Figure 4 As shown, the bearing assembly 32 includes a fixed frame 321 and a plurality of bearing plates 322. The fixed frame 321 is connected to the output end of the second rotation drive assembly 31 by transmission. The plurality of bearing plates 322 are connected to the fixed frame 321. Each bearing plate 322 can bear solar cells, and when at least one bearing plate 322 bears a solar cell and is located at a processing station, at least one bearing plate 322 bears a solar cell and is located at a material unloading station. The above arrangement enables the fixed frame 321 to synchronously realize the transportation of the processed solar cells from the processing station to the material unloading station and the transportation of the solar cells to be processed from the material unloading station to the processing station in the process of driving the plurality of bearing plates 322 to rotate synchronously, thereby further improving the processing efficiency of the solar cells.

[0056] Optionally, in this embodiment, the supporting assembly 32 includes four supporting plates 322. When two supporting plates 322 carry solar cells and are located at the processing station, the remaining two supporting plates 322 carry solar cells and are located at the unloading station. The above arrangement enables the fixing frame 321 to synchronously realize the transportation of two processed solar cells from the processing station to the unloading station and the transportation of two solar cells to be processed from the unloading station to the processing station in the process of driving the multiple supporting plates 322 to rotate synchronously, thereby further improving the processing efficiency of the solar cells. It should be noted that in other embodiments, the specific number of the suction supporting plates 322 can be set according to demand.

[0057] In this embodiment, the fixing frame 321 includes a first connecting plate 3211 and two second connecting plates 3212. The first connecting plate 3211 is drivingly connected to the output end of the second rotating drive assembly 31. The opposite ends of the first connecting plate 3211 are respectively connected to the two second connecting plates 3212. The two second connecting plates 3212 are arranged oppositely and in parallel, and the opposite ends of each second connecting plate 3212 are connected to a carrier plate 322. The structural design of the fixing frame 321 makes the fixing frame 321 present an "I" shape, which effectively improves the structural strength and structural stability of the fixing frame 321, and also improves the rationality of the layout of multiple carrier plates 322.
