Description

Technical Field

[0001] The present invention relates to the technical field of semiconductor processing, and in particular to a three-station photovoltaic sheet processing device. Background Art

[0002] Photovoltaic cells are one of the important components of solar cell modules. Their main function is to convert light energy into electrical energy, thereby realizing solar power generation. Since solar energy is a renewable and clean energy, solar cells have received more and more attention.

[0003] During the production of photovoltaic cells, a suction cup assembly is often required to grab the photovoltaic cells from the transmission line to the turntable, and then the turntable drives the photovoltaic cells into the processing position, so as to achieve continuous operation. The existing turntable structures used for solar energy processing include a four-station turntable and a two-station turntable. Among them, the two-station turntable needs to rotate 180° within 0.1s for each processing. The fast rotation speed makes the photovoltaic cells susceptible to large centrifugal forces, resulting in flying pieces and damage to the photovoltaic cells. The four-station turntable needs to rotate 90° within 0.1s for each processing. Since the four stations rotate at the same time, the rotary motor needs to provide a very large rotational acceleration, so a set of water cooling devices needs to be added, which increases the cost of the equipment. It can be seen that the existing turntable structures cannot realize the processing of photovoltaic cells well. Summary of the invention

[0062] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0063] The overall structure, working principle and technical effects of the three-station photovoltaic panel processing equipment provided by the present invention are described in detail below through embodiments and in conjunction with the accompanying drawings.

[0064] Please refer to Figures 1 to 7 The three-station photovoltaic sheet processing equipment 100 includes a body 110, a three-station turntable assembly 130, a gripping assembly 150 and a processing assembly 180. The body 110 is the mounting base of the three-station photovoltaic sheet processing equipment 100, and most of the parts, components and assemblies of the three-station photovoltaic sheet processing equipment 100 are mounted on the body 110. The three-station turntable assembly 130 is rotatably arranged on the body 110. The three-station turntable assembly 130 is provided with a first station 131, a second station 132 and a third station 133. The first station 131, the second station 132 and the third station 133 are arranged in an equilateral triangle with the rotation axis of the three-station turntable assembly 130 as the center. The first station 131, the second station 132 and the third station 133 are all used to fix photovoltaic sheets. The grabbing assembly 150 is disposed on the machine body 110 and is used to grab the photovoltaic sheet to the first station 131 and to grab downward the photovoltaic sheet processed in the third station 133. The processing assembly 180 is disposed on the machine body 110 to process the photovoltaic sheet in the second station 132.

[0065] In this embodiment, the turntable 135 is configured as a three-station turntable assembly 130, and the first station 131, the second station 132 and the third station 133 are arranged in an equilateral triangle with the rotation axis of the three-station turntable assembly 130 as the center. In this way, each station occupies a 120° circular angle of the turntable 135, which can avoid the problem of flying flakes caused by large centrifugal force. The three-station does not have high requirements on the rotation acceleration of the drive motor 134 of the three-station turntable assembly 130, so there is no need to increase water cooling, which is lower cost.

[0066] Please refer to Figures 1 to 7, wherein the three-station turntable assembly 130 includes a drive motor 134 and a turntable 135 on which the output shaft of the drive motor 134 is arranged. The drive motor is fixedly mounted on the body 110. The turntable 135 is connected to the rotating shaft of the drive motor in a transmission manner. The drive motor 134 can drive the turntable 135 to rotate. The first station 131, the second station 132 and the third station 133 are arranged on the turntable 135 in an equilateral triangle with the rotation axis of the turntable 135 as the center. It can be seen from the figure that the first station 131, the second station 132 and the third station 133 are enclosed in the middle in sequence to form an equilateral triangle, and the drive motor 134 is arranged at the center of the equilateral triangle.

[0067] In this embodiment, the driving motor 134 is a DD motor, which has the effects of high energy efficiency, low noise, high precision and long life.

[0068] Furthermore, the first station 131, the second station 132 and the third station 133 are all provided with two fixed grooves along the length direction of each side of the equilateral triangle. There are six fixed grooves in total, which are used to accommodate and fix the photovoltaic sheets. The first station 131 is a loading station, and the grabbing assembly 150 can grab two unprocessed photovoltaic sheets and load them into the two fixed grooves of the first station 131 respectively. After that, the driving motor drives the turntable 135 to rotate 120°, so that the two photovoltaic sheets of the first station 131 are rotated to the second station 132 for processing. After the processing is completed, the driving motor drives the turntable 135 to rotate 120° again, so that the two processed photovoltaic sheets of the second station 132 are transferred to the third station 133, and the third station 133 is a unloading station. The grabbing assembly 150 grabs the photovoltaic sheet on the third station 133. In this way, loading, processing and unloading can be realized in sequence, thereby realizing assembly line production. The most important thing is that the turntable 135 can be realized without reversing.

[0069] Please refer to Figures 1 to 7 In this embodiment, the grabbing assembly 150 includes a driving assembly 151, a mechanical arm 152 and a suction cup 153. The driving assembly 151 is disposed on the body 110. The mechanical arm 152 is disposed on the driving assembly 151, and the driving assembly 151 can drive the mechanical arm 152 to rotate along the axis of the driving assembly 151. The suction cup 153 is disposed on the mechanical arm 152, and the suction cup 153 is used to grab the photovoltaic sheet. The first station 131 and the third station 133 are both located on the same circumference with the rotation center of the driving assembly 151 as the center of the circle. The driving assembly 151 drives the mechanical arm 152 to rotate so that the suction cup 153 corresponds to the first station 131 or the third station 133.

[0070] In this embodiment, the first station 131 and the third station 133 are arranged on the same circumference of the rotation center of the grabbing assembly 150, so that the grabbing assembly 150 can load materials to the first station 131 and unload materials to the third station 133 at the same time.

[0071] In this embodiment, the three-station photovoltaic sheet processing equipment 100 further includes a feed conveyor line 190 and a discharge conveyor line 210. The feed conveyor line 190 is disposed on the machine body 110 and is disposed near the first station 131. The discharge conveyor line 210 is disposed on the machine body 110 and is disposed near the third station 133. The suction cup 153 can grab the photovoltaic sheet on the feed conveyor line 190 to the first station 131 and the suction cup 153 can grab the photovoltaic sheet on the third station 133 to the discharge conveyor line 210.

[0072] In this embodiment, a feed conveyor line 190 is provided so that the photovoltaic sheets to be processed can be fed to the grab assembly 150 through the feed conveyor line 190. A discharge input line is provided so that the processed photovoltaic sheets can be grabbed by the grab assembly 150 to the discharge conveyor line 210, thereby transporting the processed photovoltaic sheets away.

[0073] Generally, the photovoltaic sheets to be processed are placed on a flower basket, each flower basket is provided with multiple layers, and multiple photovoltaic sheets are stacked at intervals, and two adjacent photovoltaic sheets are arranged at intervals under the support of the flower basket. The end of the feed conveyor line 190 can be extended and extended into the gap between two photovoltaic sheets, and the upper photovoltaic sheet is conveyed toward the first workstation 131 due to the conveyance of the feed conveyor line 190.

[0074] Please refer to Figures 1 to 7 In this embodiment, the end of the feeding conveyor line 190 close to the first station 131 has a first loading station and a second loading station in sequence along the length direction of the feeding conveyor line 190, and each of the first loading station and the second loading station can be placed with a corresponding photovoltaic sheet. The suction cup 153 of the grabbing assembly 150 can grab two photovoltaic sheets on the first loading station and the second loading station into the two fixed grooves of the first station 131 at one time.

[0075] It should be noted that the first loading station and the second loading station are two specific positions of the feed conveyor line 190. The feed conveyor line 190 is a transmission belt structure, which can convey the photovoltaic panels carried on the upper side along a preset direction. Generally, the feed conveyor line 190 is formed by splicing multiple belt transmission lines. Of course, in some other embodiments of the present application, the feed conveyor line 190 can also be a belt transmission line.

[0076] Please refer to Figures 1 to 7In this embodiment, the end of the feeding conveyor line 190 near the third station 133 has a first unloading station and a second unloading station in sequence along the length direction of the unloading conveyor line 210. The first unloading station and the second unloading station can each be placed with a corresponding photovoltaic sheet. The suction cup 153 of the grabbing assembly 150 can grab the photovoltaic sheets in the two fixed grooves of the third station 133 at one time and move them to the first unloading station and the second unloading station, and then transfer them through the unloading conveyor line 210 and stack them in the empty flower basket through the telescopic belt at the end.

[0077] It should be noted that the first unloading station and the second unloading station are two specific positions of the unloading conveyor line 210. The unloading conveyor line 210 is a transmission belt structure, which can convey the photovoltaic sheet carried on it along a preset direction. Generally, the unloading conveyor line 210 is formed by splicing multiple belt transmission lines. Of course, in some other embodiments of the present application, the unloading conveyor line 210 can also be a belt transmission line.

[0078] In this embodiment, the feed conveyor line 190 and the discharge conveyor line 210 are arranged in parallel, and the angle between the feed conveyor line 190 and the first workstation 131 is 30°, the angle between the third workstation 133 and the discharge conveyor line 210 is 30°, and the feed conveyor line 190 and the discharge conveyor line 210 are both arranged vertically relative to the second workstation 132.

[0079] Further, the suction cup 153 includes a first suction cup 154 ​​and a second suction cup 155. The first suction cup 154 ​​and the second suction cup 155 are both rotatably mounted on the mechanical arm 152, and the angle between the line connecting the rotation center of the first suction cup 154 ​​and the rotation center of the mechanical arm 152 and the line connecting the rotation center of the second suction cup 155 and the rotation center of the mechanical arm 152 is 120°.

[0080] Please refer to Figures 1 to 7 In this embodiment, the suction cup 153 is set as the first suction cup 154 ​​and the second suction cup 155, and the line connecting the two and the rotation center of the robot arm 152 is 120°. In this way, when the robot arm 152 rotates to the first suction cup 154 ​​and the first loading station and the second loading station on the feeding conveyor line 190, the second suction cup 155 also corresponds to the two photovoltaic cells on the third station 133 of the turntable 135. Therefore, when the feeding conveyor line 190 loads the first station 131, the photovoltaic cells of the third station 133 can be unloaded to the discharging conveyor line 210 at the same time, thereby improving efficiency.

[0081] After the first suction cup 154 ​​grabs the photovoltaic cell on the feed conveyor line 190 and the second suction cup 155 grabs the photovoltaic cell on the third station 133, the robot arm 152 rotates 60 degrees. At this time, the photovoltaic cell grabbed by the first suction cup 154 ​​corresponds to the first station 131, and the photovoltaic cell grabbed by the second suction cup 155 corresponds to the first unloading station and the second unloading station on the discharge conveyor line 210.

[0082] Further, the mechanical arm 152 includes a connecting portion 174 and a first extension portion 175 and a second extension portion 176 connected to the connecting portion 174. The connecting portion 174 is connected to the output shaft of the driving assembly 151, generally by a fastener. The first extension portion 175 and the second extension portion 176 both extend along the radial direction of the connecting portion 174, and the angle between the first and second extension portions 175 and 176 is 120°. The first suction cup 154 ​​is disposed on the first extension portion 175, and the second suction cup 155 is disposed on the second extension portion 176. The installation positions of the first suction cup 154 ​​and the second suction cup 155 are located on the same circumference.

[0083] Since the central angle of the line connecting the feed conveyor line 190 and the first station 131 with the center of rotation of the robot arm 152 is 60°, and the angle between the first station 131 and the feed conveyor line 190 is 30°. Since the central angle of the line connecting the discharge conveyor line 210 and the third station 133 with the center of rotation of the robot arm 152 is 60°, and the angle between the third station 133 and the discharge conveyor line 210 is 30°. The two photovoltaic sheets are arranged vertically on the feed conveyor line 190. At this time, the first suction cup 154 ​​must grab the two photovoltaic sheets in a manner perpendicular to the first extension portion 175. When placing the photovoltaic sheet on the first station 131, due to the three-station setting of the turntable 135, the first suction cup 154 ​​needs to be rotated to be parallel to the first extension portion 175 before the two photovoltaic sheets can be placed in the two station slots of the first station 131. When the second suction cup 155 grabs the processed photovoltaic sheet on the third station 133 and takes it to the discharge conveyor line 210 , it also needs to rotate due to the angle problem.

[0084] Please refer to Figures 1 to 7Based on the above problems, in this embodiment, the grabbing assembly 150 further includes a transmission assembly 156. The transmission assembly 156 is configured to drive the first suction cup 154 ​​to rotate relative to the mechanical arm 152, so as to adjust the angle of the first suction cup 154 ​​when the first suction cup 154 ​​grabs the photovoltaic sheet from the feeding conveyor line 190 to the first station 131 so that the first suction cup 154 ​​corresponds to the feeding conveyor line 190 and the first station 131. That is, when the first suction cup 154 ​​is about to grab the first loading station and the second loading station on the feeding conveyor line 190, the transmission assembly 156 drives the first turntable 135 to rotate so that the direction of the first suction cup 154 ​​corresponds to the photovoltaic sheets on the first loading station and the second loading station, so that the first suction cup 154 ​​can grab two photovoltaic sheets at the same time. After the first suction cup 154 ​​grabs onto the feed conveyor line 190 and before placing it on the first workstation 131, the transmission assembly 156 needs to drive the first suction cup 154 ​​to rotate so that the two photovoltaic panels grabbed by the first suction cup 154 ​​correspond one by one to the two fixed grooves of the first workstation 131, thereby achieving precise grabbing and placement during the loading process.

[0085] Furthermore, the transmission assembly 156 is also configured to drive the second suction cup 155 to rotate relative to the mechanical arm 152, so as to adjust the angle of the second suction cup 155 when the second suction cup 155 grabs the photovoltaic sheet from the third station 133 to the discharge conveyor line 210 so that the second suction cup 155 corresponds to the discharge conveyor line 210 and the third station 133. That is, when the second suction cup 155 is to grab the photovoltaic sheet in the two fixed grooves of the third station 133, the transmission assembly 156 needs to drive the second suction cup 155 to rotate to be parallel to the second extension 176, so that the second suction cup 155 will correspond to the two fixed grooves on the third station 133, so that the second suction cup 155 can grab two photovoltaic sheets on the third station 133 at the same time. After the second suction cup 155 grabs the two photovoltaic panels on the third station 133 and places them in front of the discharge conveyor line 210, the transmission assembly 156 needs to drive the second suction cup 155 to rotate so that the two photovoltaic panels grabbed by the second suction cup 155 correspond one by one to the two fixed grooves of the first station 131, and the second suction cup 155 is perpendicular to the second extension part 176, thereby achieving precise grabbing and placement during the unloading process.

[0086] Please refer to Figures 1 to 7In this embodiment, the transmission assembly 156 includes a fixed shaft 157, a synchronous wheel assembly 158, a first synchronous wheel 159, a second synchronous wheel 161 and a conveyor belt 162. The fixed shaft 157 is fixedly arranged relative to the machine body 110, and the axis of the fixed shaft 157 coincides with the rotation axis of the driving assembly 151. The synchronous wheel assembly 158 is fixedly arranged on the fixed shaft 157. The first synchronous wheel 159 is installed on the first suction cup 154, and the axis of the first synchronous wheel 159 coincides with the rotation axis of the first suction cup 154. The second synchronous wheel 161 is installed on the second suction cup 155, and the axis of the second synchronous wheel 161 coincides with the rotation axis of the second suction cup 155. The conveyor belt 162 is sleeved on the outer periphery of the synchronous wheel assembly 158, the first synchronous wheel 159 and the second synchronous wheel 161. When the driving assembly 151 drives the mechanical arm 152 to rotate, the conveyor belt 162 can drive the first synchronous wheel 159 and the second synchronous wheel 161 to rotate. This arrangement allows the first suction cup 154 ​​and the second suction cup 155 to rotate in conjunction with each other during the rotation of the mechanical arm 152, and the linkage can be achieved without the need for a power element such as a motor.

[0087] Please refer to Figures 1 to 7 In this embodiment, the driving assembly 151 is a DD motor, and the inner side of the central axis is hollow. The fixed shaft 157 is fixedly connected to the body 110, and extends from the hollow area inside the central axis of the driving assembly 151 to the top of the driving assembly 151, and extends to the top of the DD motor, so that the fixed shaft 157 is in line with the rotation axis of the driving assembly 151. The synchronous wheel assembly 158 is fixedly mounted on the fixed shaft 157. Since the synchronous wheel assembly 158 is fixed and does not rotate, the first synchronous wheel 159 is mounted on the first suction cup 154 ​​and can rotate with the first suction cup 154, and the second synchronous wheel 161 is mounted on the second suction cup 155 and can rotate with the second suction cup 155. The synchronous wheel assembly 158, the first synchronous wheel 159 and the second synchronous wheel 161 are linked by the conveyor belt 162. In this way, the first suction cup 154 ​​and the second suction cup 155 can be driven to rotate by the swing of the mechanical arm 152 during the swinging process of the mechanical arm 152.

[0088] Further, the synchronous wheel assembly 158 includes a third synchronous wheel 163 and a fourth synchronous wheel 164, and the third synchronous wheel 163 and the fourth synchronous wheel 164 are fixedly arranged on the fixed shaft 157. The first synchronous wheel 159, the second synchronous wheel 161, the third synchronous wheel 163 and the fourth synchronous wheel 164 are all synchronous toothed belt wheels, and the gear ratio of the first synchronous wheel 159 and the third synchronous wheel 163 is 1:1.5, and the gear ratio of the second synchronous wheel 161 and the fourth synchronous wheel 164 is 1:1.5. The conveyor belt 162 includes a first synchronous toothed belt 165 and a second synchronous toothed belt 166, and the first synchronous toothed belt 165 is sleeved on the outer periphery of the third synchronous wheel 163 and the first synchronous wheel 159, and the second synchronous toothed belt 166 is sleeved on the outer periphery of the fourth synchronous wheel 164 and the second synchronous wheel 161.

[0089] That is to say, during each loading and unloading process, the driving assembly 151 drives the mechanical arm 152 to rotate 60°. The angle between the first extension 175 and the second extension 176 of the mechanical arm 152 is 120°. When the first suction cup 154 ​​takes the material from the feeding conveyor line 190, the angle between the first suction cup 154 ​​and the first extension 175 is 90°, and the angle between the second suction cup 155 and the second extension 176 is 0°. At this time, the first suction cup 154 ​​can grab the two photovoltaic panels of the first loading station and the second loading station on the feeding conveyor line 190, and the second suction cup 155 can also grab the two photovoltaic panels on the third station 133. After the driving assembly 151 drives the mechanical arm 152 to rotate 60°, the first suction cup 154 ​​will be above the first station 131, and the second suction cup 155 will be above the discharge conveyor line 210. In the process of driving the mechanical arm 152 to rotate 60° by the driving component 151, the first suction cup 154 ​​and the second suction cup 155 rotate 90° due to the gear ratio of 1:1.5, and the angle between the first suction cup 154 ​​and the first extension portion 175 is changed from 90° (the first suction cup 154 ​​and the first extension portion 175 are perpendicular) to 0° (the first suction cup 154 ​​and the first extension portion 175 are parallel), and the angle between the second suction cup 155 and the second extension portion 176 is changed from 0° (the second suction cup 155 and the second extension portion 176 are parallel) to 90° (the second suction cup 155 and the second extension portion 176 are perpendicular). This arrangement can increase the angles of the first suction cup 154 ​​and the second suction cup 155 during the rotation of the mechanical arm 152 so that the first suction cup 154 ​​and the second suction cup 155 have corresponding angles at corresponding positions.

[0090] It is worth noting that in the present embodiment, the fixed shaft 157 is fixed relative to the body 110, and the third synchronous wheel 163 and the fourth synchronous wheel 164 are relatively fixed to the fixed shaft 157 and do not rotate. In this way, it is ensured that the robot arm 152 is driven and rotated by the driving component 151, and the corresponding first suction cup 154 ​​and second suction cup 155 are driven to rotate through the first synchronous toothed belt 165 and the second synchronous toothed belt 166 without the need to set up a separate driving motor or other power elements.

[0091] Of course, in some other embodiments of the present application, the rotation of the first suction cup 154 ​​relative to the first extension portion 175 and the rotation of the second suction cup 155 relative to the second extension portion 176 can be controlled by a separate motor drive. For example, a first motor is provided on the first extension portion 175, and the first suction cup 154 ​​is mounted on the output shaft of the first motor. The first suction cup 154 ​​can be driven by the first motor to rotate 90° while the mechanical arm 152 swings. A second motor is provided on the second extension portion 176, and the second suction cup 155 is mounted on the output shaft of the second motor. The second motor drives the second suction cup 155 to rotate 90° while the mechanical arm 152 swings. Secondly, the rotation of the first suction cup 154 ​​and the second suction cup 155 can also be driven to rotate simultaneously by a motor in combination with a belt or the like.

[0092] Please refer to Figures 1 to 7 In this embodiment, the first suction cup 154 ​​includes a first mounting seat 167, a first suction cup body 168 and a second suction cup body 169. The first suction cup body 168 and the second suction cup body 169 are fixedly installed on the first mounting seat 167 at intervals, and the first mounting seat 167 is rotatably installed on the mechanical arm 152. Negative pressure chambers are provided in the first suction cup body 168 and the second suction cup body 169. By using pipelines to form negative pressure in the negative pressure chamber, the photovoltaic sheet of the first loading station can be adsorbed on the first suction cup body 168 and the photovoltaic sheet of the second loading station can be adsorbed on the second suction cup body 169. After the mechanical arm 152 rotates 60° to the first station 131 to release the negative pressure, the two photovoltaic sheets adsorbed by the first suction cup body 168 and the second suction cup body 169 will fall into the two fixed grooves of the first station 131 under the action of gravity.

[0093] Specifically, the first suction cup body 168 and the second suction cup body 169 are fixedly mounted at both ends of the length direction of the first mounting seat 167 and are parallel to each other. The first mounting seat 167 has a first rotating shaft 178, and the first rotating shaft 178 is mounted on the first extension portion 175 through a bearing. The first synchronous wheel 159 is fixedly mounted on the first rotating shaft 178, so that the first suction cup 154 ​​assembly can be better rotated relative to the first extension portion 175.

[0094] In this embodiment, the second suction cup 155 includes a second mounting seat 171, a third suction cup body 172 and a fourth suction cup body 173. The third suction cup body 172 and the fourth suction cup body 173 are fixedly installed on the second mounting seat 171 at intervals, and the second mounting seat 171 is rotatably installed on the mechanical arm 152. Negative pressure chambers are provided in the third suction cup body 172 and the fourth suction cup body 173. The photovoltaic sheet of the third station 133 can be adsorbed on the third suction cup body 172 and the fourth suction cup body 173 by forming negative pressure in the negative pressure chamber through pipelines. After the mechanical arm 152 rotates 60° to the first unloading station and the second unloading station of the unloading conveyor line 210, the negative pressure is released, and the two photovoltaic sheets adsorbed by the third suction cup body 172 and the fourth suction cup body 173 will fall to the first unloading station and the second unloading station under the action of gravity and be carried on the unloading conveyor line 210.

[0095] Specifically, the third suction cup body 172 and the fourth suction cup body 173 are fixedly mounted at both ends of the length direction of the second mounting seat 171 and are parallel to each other. The second mounting seat 171 has a second rotating shaft 179, and the second rotating shaft 179 is mounted on the second extension portion 176 through a bearing. The second synchronous wheel 161 is fixedly mounted on the second rotating shaft 179, so that the second suction cup 155 assembly can be better rotated relative to the second extension portion 176.

[0096] It is worth noting that the mechanical arm 152 of the present embodiment only rotates and does not move up and down in the height direction, which makes the movement simpler and improves efficiency. The height difference between the first suction cup body 168 and the second suction cup body 169 and the bearing surface of the feed conveyor line 190 is set appropriately, and the negative pressure formed by the first suction cup body 168 and the second suction cup body 169 can be used to directly suck up the photovoltaic sheet carried on the feed conveyor line 190 and separate it from the feed conveyor line 190. The height difference between the first suction cup body 168 and the second suction cup body 169 and the first station 131 is set appropriately. After the negative pressure of the first suction cup body 168 and the second suction cup body 169 is released, the photovoltaic sheet can also fall to the two fixed grooves of the first station 131 under the action of gravity. The appropriate height difference will not cause the photovoltaic sheet to be damaged when it falls to the first station 131. Secondly, the present embodiment provides that the loading of the first suction cup 154 ​​component and the unloading of the second suction cup 155 component are carried out synchronously.

[0097] In this embodiment, the machine body 110 is provided with two sets of processing components 180 corresponding to the second workstation 132. The two sets of processing components 180 are provided so that two sets of photovoltaic sheets can be processed simultaneously, which can improve the processing efficiency.

[0098] Further, in this embodiment, the processing component 180 is a laser doping processing component 180, which can perform laser doping on the photovoltaic sheet. Of course, in some other embodiments of the present application, the processing component 180 can also be replaced by other processing components 180.

[0099] Please refer to Figures 1 to 7 , since it is necessary to replace the flower basket and other operations during the processing of the photovoltaic sheet, it will lead to the inability to continuously process and affect the efficiency. In order to enable the three-station photovoltaic sheet processing equipment 100 to operate continuously, in this embodiment, the three-station laser miscellaneous equipment also includes a first temporary storage component 230 and a second temporary storage component 250. The first temporary storage component 230 is arranged on the body 110 and corresponds to the feeding conveyor line 190. The first temporary storage component 230 can temporarily store the photovoltaic sheets on the feeding conveyor line 190. In this way, during the processing of the photovoltaic sheet in the processing component 180, some photovoltaic sheets to be processed can be temporarily stored on the first temporary storage component 230, and during the process of replacing the flower basket, the photovoltaic sheets temporarily stored in the first temporary storage component 231 can be put back to the feeding conveyor line 190, so that the three-station photovoltaic sheet processing equipment 100 is not affected by the replacement of the flower basket and can operate continuously. Similarly, the processed photovoltaic sheets also need to be placed on the flower basket by the discharge conveyor line 210, and the flower basket needs to be replaced after the flower basket is full. In this embodiment, the second temporary storage component 250 is disposed on the machine body 110 and is disposed corresponding to the discharge conveyor line 210. The second temporary storage component 250 can temporarily store the photovoltaic sheets on the discharge conveyor line 210. After the empty flower basket is replaced, the photovoltaic sheets temporarily stored on the second temporary storage component 250 can be put back to the discharge conveyor line 210 and stacked on the flower basket, thus ensuring continuous action and improving efficiency.

[0100] Specifically, the first temporary storage component 230 includes a first temporary storage member 231, a first connecting column 232 and a first driving member 233. The first connecting column 232 is fixedly disposed on the body 110, the first temporary storage member 231 is movably mounted on the first connecting column 232, the first driving member 233 is disposed on the first connecting column 232, and the first driving member 233 is configured to drive the first temporary storage member 231 to move in the up and down directions relative to the first connecting column 232. The first temporary storage member 231 has a first top plate 234 and a first side plate 235 and a second side plate 236 disposed on both sides of the first top plate 234 in the length direction. The first side plate 235 and the second side plate 236 are mutually connected. A plurality of first plug-in grooves 237 are arranged at intervals on both sides along the height direction, and the first side plate 235 and the second side plate 236 are located on both sides in the width direction of the feed conveyor line 190; when the photovoltaic cells on the feed conveyor line 190 need to be temporarily stored, the photovoltaic cells carried on the feed conveyor line 190 can be plugged into the first plug-in grooves 237 driven by the feed conveyor line 190, and then the first temporary storage member 231 is lifted as a whole under the first driving member 233 to lift the photovoltaic cells plugged in the first plug-in grooves 237 for temporary storage, and make the upper and lower first plug-in grooves 237 of the first temporary storage member 231 flush with the height of the photovoltaic cells carried on the feed conveyor line 190.

[0101] In this embodiment, a plurality of first insertion slots 237 are arranged on opposite sides of the first side plate 235 and the second side plate 236 of the first temporary storage member 231 . Each of the first insertion slots 237 can temporarily store one photovoltaic cell, thereby temporarily storing more photovoltaic cells.

[0102] Specifically, the width of the feed conveyor line 190 is smaller than the width of the photovoltaic sheet, so that when the photovoltaic sheet is carried on the feed conveyor line 190, both sides extend out of the feed conveyor line 190. In normal operation, the photovoltaic sheet carried on the feed conveyor line 190 passes through the first plug-in slot 237 under the action of the feed conveyor line 190 to enter the first loading station and the second loading station. During temporary storage, when the photovoltaic cell transmitted by the feed conveyor line 190 passes through the first plug-in slot 237, the first temporary storage member 231 will be driven and lifted by the first driving member 233, and the photovoltaic cell will be lifted up and separated from the feed conveyor line 190 and temporarily stored in this first plug-in slot 237. The first plug-in slot 237 below the lifted first temporary storage member 231 will be at the same height as the photovoltaic cell carried on the feed conveyor line 190. If the next photovoltaic cell is not temporarily stored, it will pass through the first plug-in slot 237 under the action of the feed output line and enter the next workstation. If the temporarily stored photovoltaic cell is plugged into the first plug-in slot 237 under the action of the feed conveyor line 190, the first temporary storage member 231 will be lifted again, and this photovoltaic cell will also be temporarily stored. When the temporarily stored photovoltaic sheets need to be returned to the feeding conveyor line 190 for example, when replacing the flower basket, the height of the first temporary storage member 231 only needs to be lowered so that the temporarily stored photovoltaic sheets can contact the bearing surface of the feeding conveyor line 190 and can be transferred to the next station under the action of the feeding conveyor line 190. The first temporary storage assembly 230 has a simple structure and control, and can temporarily store more photovoltaic sheets.

[0103] In this embodiment, the second temporary storage component 250 includes a second temporary storage member 251, a second connecting column 252 and a second driving member 253. The second connecting column 252 is fixedly disposed on the body 110, the second temporary storage member 251 is movably mounted on the second connecting column 252, the second driving member 253 is disposed on the second connecting column 252, and the second driving member 253 is configured to drive the second temporary storage member 251 to move in the up and down directions relative to the second connecting column 252. The second temporary storage member 251 has a second top plate 254 and a third side plate 255 and a fourth side plate 256 disposed on both sides of the second top plate 254 in the length direction. The third side plate 255 and the fourth side plate 256 are mutually connected. A plurality of second plug-in slots 257 are arranged at intervals on both sides of the pair along the height direction, and the third side plate 255 and the fourth side plate 256 are located on both sides of the width direction of the discharge conveyor line 210; when the photovoltaic sheets on the discharge conveyor line 210 need to be temporarily stored, the photovoltaic sheets carried on the discharge conveyor line 210 can be plugged into the second plug-in slots 257 driven by the discharge conveyor line 210, and then the second temporary storage member 251 is lifted as a whole under the drive of the second driving member 253 to lift and temporarily store the photovoltaic sheets plugged into the second plug-in slots 257, and the second temporary storage member 251 is made to be flush with the height of the photovoltaic sheets carried on the discharge conveyor line 210. The operating principle of the second temporary storage component 250 is the same as the structure and principle of the first temporary storage component 230, which will not be repeated here.

[0104] Please refer to Figures 1 to 7 In this embodiment, the three-station photovoltaic sheet processing equipment 100 further includes a position detection module 260 and a defect detection module 270. The position detection module 260 is disposed on the body 110 and is disposed corresponding to the first station 131. The position detection module 260 is configured to detect the position information of the photovoltaic sheet on the first station 131. So that the processing component 180 performs laser impurity treatment on the photovoltaic sheet according to the position information. The defect detection module 270 is disposed on the body 110 and is disposed corresponding to the third station 133. The defect detection module 270 is configured to detect the quality of the photovoltaic sheet on the third station 133.

[0105] Since the positions of the photovoltaic sheets placed on the first station 131 each time will be different, the position differences will affect the processing. In this embodiment, a position detection module 260 is set at the first station 131. The position detection module 260 can detect the position of the photovoltaic sheet placed on the first station 131, so that the processing component 180 can process the photovoltaic sheet according to the position of the photovoltaic sheet, thereby ensuring the processing accuracy of each photovoltaic sheet. Secondly, the position detection and loading share a station, which can achieve the miniaturization of the equipment. The position detection module 260 can enable the viewing angle detection module to capture the position of the photovoltaic sheet relative to the turntable 135 through the viewing angle sensor. The defect detection module 270 uses a CCD detection component to detect whether the processed photovoltaic sheet has defects. Setting the defect detection module 270 at the third station 133 and sharing a station with the unloading station can achieve the miniaturization of the equipment.

[0106] Secondly, the three-station photovoltaic cell processing equipment 100 also includes a waste kicking component 280, which is arranged between the second unloading station and the second temporary storage component 250. When the defect detection module 270 detects that the photovoltaic cell has defects, the waste kicking component 280 will grab the corresponding photovoltaic cell from the discharge conveyor line 210 into the waste cell box.

[0107] Please refer to Figure 8 In this embodiment, two production lines are arranged on the machine body 110, so that the processing efficiency can be improved. Of course, in other embodiments of the present application, the number of production lines can be determined according to demand, and can also be one or more.

[0108] In summary, in this embodiment, the turntable 135 is configured as a three-station turntable assembly 130, and the first station 131, the second station 132 and the third station 133 are arranged in an equilateral triangle with the rotation axis of the three-station turntable assembly 130 as the center. In this way, each station occupies a 120° circular angle of the turntable 135, which can avoid the problem of flying flakes caused by large centrifugal force, and the three stations do not have high requirements on the rotation acceleration of the driving motor 134 of the three-station turntable assembly 130, so there is no need to increase water cooling and the cost is lower.

[0109] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
