Abstract
Description
Technical Field
[0001] This application relates to the field of conveying technology, and in particular to a conveying device. Background Technology
[0002] During the transport and transfer of solar cells, the solar cells loaded in the basket are first taken out by a robotic arm and placed on a conveyor belt. Then, after being regulated by a sorting device, the solar cells are transported to the lifting platform area. The lifting platform lifts the solar cells, and the gantry suction device transfers the solar cells to the carrier plate.
[0003] However, during the conveying and lifting process, solar cells may break into fragments. If these fragments are not cleaned up in time, they can cause extensive scratches on the cells, or cause them to fall off the edge of the lifting platform during lifting, resulting in missed suction and fragmentation. In traditional technology, if fragments are found during the conveying and transfer process, personnel need to enter the device to clean them up. This cleaning process not only poses a risk of mechanical injury but may also contaminate the solar cells. Therefore, a conveying device capable of automatically cleaning up fragments is needed.

[0032] In traditional technologies, solar cell overlap is a common problem during the conveying process. This overlap occurs when a solar cell deviates from its designated position, potentially causing it to collide with surrounding components and break during lifting. These fragments falling onto the lifter not only increase the risk of overlap but also scratch the cells, affecting their quality. While manual cleaning is possible, it requires shutting down the system, impacting production efficiency and potentially causing secondary contamination of the conveying equipment, further reducing solar cell yield.
[0033] Based on this, this application provides a conveying device, such as... Figure 1 , Figure 2 and Figure 3 As shown, the conveying device includes a conveying mechanism 100, a detection mechanism, and a cleaning mechanism.
[0034] The conveying mechanism 100 includes a lifter 110 and a film picker (not shown in the figure). The film picker is movably mounted on the lifter 110, which carries the film, and the film picker is used to pick up and transfer the film from the lifter 110. The detection mechanism includes at least one image acquisition unit 200, which is used to acquire images of the lifter 110 to determine the location of foreign objects. The cleaning mechanism includes at least one cleaner 300, which is electrically connected to the image acquisition unit 200. The cleaner 300 is used to clean the lifter 110 according to the location of the foreign objects acquired by the image acquisition unit 200.
[0035] This application, by installing an image acquisition device 200 on the lifting device 110, allows the image acquisition device 200 to photograph and analyze the lifting device 110 after the cell picker transfers the battery cells, thus determining the location of debris and other foreign objects. The cleaning mechanism then moves to the location of the foreign objects on the lifting device 110 based on this location information to perform cleaning. By incorporating the image acquisition device 200 and the cleaning device 300, this application effectively removes debris and other foreign objects from the conveying device, significantly improving production efficiency and reducing contamination of the conveyed materials.
[0036] Optionally, the image acquisition device 200 is positioned above the lifter 110.
[0037] Optionally, the cleaner 300 is movably positioned above the lifter 110.
[0038] It should be noted that the image acquisition device 200 in this application can take pictures of the lifting device 110, and the position of foreign objects can be analyzed through the pictures. For example, the image acquisition device 200 can be a CCD camera. It is understood that the image acquisition device 200 can acquire images of the lifting device 110 after the film picker transfers the film on the lifting device 110, so as to avoid the film picker interfering with the image acquisition.
[0039] Understandably, during the operation of the lifter 110, the cleaner 300 is not in the lifting stroke of the lifter 110, therefore the cleaner 300 will not affect the operation of the lifter 110. After the lifter 110 completes lifting and returns to its initial position, based on the information acquired by the image acquisition device 200, the cleaner 300 is driven to the lifter 110 to clean it. If no foreign objects are detected on the lifter 110, the conveying device continues to operate.
[0040] In some embodiments, the cell picker of this application can transfer the battery cells on the lifter 110. For example, the cell picker can be a gantry suction device that can pick up and transfer the battery cells on the lifter 110 in batches.
[0041] In some embodiments, such as Figure 3 and Figure 4 As shown, the cleaner 300 includes a driver 310 and a blowing element 320. The driver 310 is mounted on the lifter 110, and the blowing element 320 is connected to the driver 310. The driver 310 drives the blowing element 320 to move along the arrangement direction of the pieces on the lifter 110. The blowing port of the blowing element 320 faces the lifter 110 for blowing and cleaning the lifter 110. With the cleaner 300 configured as described above, based on the foreign object location information output by the image acquisition unit 200, the driver 310 drives the blowing element 320 to move to the foreign object location, thereby cleaning the debris on the lifter 110 by blowing, effectively improving cleaning efficiency.
[0042] Optionally, after the cleaner 300 has finished cleaning, the image acquisition device 200 can be used to take another picture of the cleaned lifter 110 to determine whether there are still foreign objects on the lifter 110. If there are still foreign objects on the lifter 110, it is necessary to clean it again or trigger an alarm.
[0043] In some embodiments, such as Figure 3 and Figure 4As shown, the actuator 310 includes at least two slide rails 311, a support frame 312, and a driving member 313. The two slide rails 311 are respectively disposed on both sides of the lifter 110. The support frame 312 spans the lifter 110, and its two ends are slidably disposed on the two slide rails 311 respectively. The blowing member 320 is disposed on the support frame 312. The driving member 313 is disposed on the slide rails 311 and is used to drive the support frame 312 to slide along the slide rails 311. With the actuator 310 configured as described above, the support frame 312 spans the lifter 110, and the blowing member 320 is disposed on the support frame 312 for movement, achieving full-coverage cleaning of the side of the lifter 110 where the battery cells are placed, effectively ensuring cleaning effect and efficiency.
[0044] In some embodiments, such as Figure 3 and Figure 4 The support frame 312 includes a crossbar 3121 and telescopic members 3122 respectively disposed at both ends of the crossbar 3121. A blowing member 320 is disposed on the crossbar 3121, and the telescopic member 3122 is slidably disposed on the slide rail 311. The telescopic member 3122 is used to extend and retract to adjust the relative distance between the crossbar 3121 and the lifter 110. In this application, the support frame 312 is configured as described above, with the portion connecting the support frame 312 to the slide rail 311 configured as the telescopic member 3122. The telescopic member 3122 can extend and retract in directions away from and towards the lifter 110, thereby adjusting the relative distance between the blowing member 320 on the crossbar 3121 and the lifter 110. This adjusts the blowing effect of the blowing member 320 on foreign objects, avoiding the problem of the blowing member 320 being too far from the foreign objects to clean them effectively, and improving the blowing and cleaning efficiency.
[0045] In some embodiments, the lifter 110 includes a plurality of side-by-side and spaced-apart lifters 111 and a lifter (not shown in the figure). Two adjacent lifters 111 are used to carry the plate, and the lifter is connected to the lifter 111 and is used to drive the lifter 111 to rise and fall.
[0046] In some embodiments, such as Figure 3 and Figure 4 As shown, the lifter 110 includes multiple limiting members 112. The limiting members 112 are disposed at one end of the lifter 111 used to support the cell, and are used to limit the cell. This application uses the limiting members 112 to limit the cell, which can reduce problems such as cell overlap and displacement during the lifting process, thereby reducing the problem of cell fragmentation during the lifting process.
[0047] It is understood that the limiting member 112 in this application can limit the position of the battery cell. For example, it can be a limiting block. By setting multiple limiting blocks on the lifter 110, the battery cell is locked in place by the cooperation between the limiting blocks. Optionally, the limiting block can be detachably set on the lifter 110, and the limiting member 112 can be replaced according to the battery cell of different sizes.
[0048] In some embodiments, the limiting member 112 includes a plurality of first limiting blocks 1121 and a plurality of second limiting blocks 1122 disposed on the support frame 111. Each first limiting block 1121 is disposed at both ends of the sheet along the length direction, and each second limiting block 1122 is disposed at both ends of the sheet along the width direction. The first limiting blocks 1121 and the second limiting blocks 1122 engage and limit the sheet.
[0049] In some embodiments, such as Figure 2 and Figure 3 As shown, the lifter 110 also includes a positioning sensor 113, which is disposed between adjacent lifters 111. The positioning sensor 113 is used to detect the position of the battery cells. By setting the positioning sensor 113 on the lifter 110, this application uses the positioning sensor 113 to detect the position of the battery cells on the lifter 110, thereby further ensuring the accuracy of the battery cell position on the lifter 110 and effectively reducing the risk of lifting debris.
[0050] In some embodiments, such as Figure 2 As shown, the conveying mechanism 100 also includes a transmitter 120 disposed between adjacent lifting frames 111, which is used to convey the sheet to the lifting frame 110.
[0051] In some embodiments, the conveyor 120 includes at least two conveyor belts 121 arranged side by side and spaced apart, with adjacent two conveyor belts 121 used to carry the sheet body; a positioning sensor 113 is disposed between the adjacent two conveyor belts 121.
[0052] Optionally, limit blocks may be provided on the conveyor belt 121 to limit the movement of the battery cells on the conveyor belt 121.
[0053] It is understandable that when the conveyor belt 121 is used to transport the battery cells, the height of the lifting frame 111 is lower than the height of the conveyor belt 121. After the conveyor belt 121 transports the battery cells to the position of the lifting frame 111, the lifting frame 111 is lowered by the action of the lifter to lift the battery cells on the conveyor belt 121. After being lifted, the battery cells on the lifting frame 111 are picked up and transferred by the cell picker.
[0054] In some embodiments, the conveying device further includes a controller. The controller is electrically connected to the image acquisition unit 200 and the cleaner 300, respectively. The controller is used to receive the location information of the foreign object output by the image acquisition unit 200, and to control the cleaner 300 to move to the location of the foreign object on the lifter 110 for cleaning based on the location information of the foreign object.
[0055] In some embodiments, the conveying device further includes an alarm. The alarm is electrically connected to the image acquisition unit 200. When the image acquisition unit 200 detects a foreign object in the lifting device 110, the alarm sounds.
[0056] In some embodiments, such as Figure 1 As shown, the conveying device also includes a housing 400. The housing 400 houses a lifter 110, a wafer picker, a detection mechanism, and a cleaning mechanism. This application utilizes the housing 400 to encapsulate the device, thereby preventing external environmental factors from contaminating the solar cells.
[0057] Exemplarily, a method for conveying battery cells using the above-described conveying device is provided, comprising the following steps:
[0058] S1. Transfer the battery cells from the basket to the conveyor belt 121. Use the conveyor belt 121 to transport the battery cells to the position of the support frame 111. When the positioning sensor 113 detects that all the battery cells are in the preset position, the conveyor belt 121 stops.
[0059] S2. Start the lifter 110 and use the lifter to raise the lifter 111 so that the lifter 111 can place the battery cells on the conveyor belt 121 on two adjacent lifters 111. At the same time, under the limiting action of the first limiting block 1121 and the second limiting block 1122, the battery cells are limited and fixed on the lifter 110.
[0060] S3. After lifting the solar cells to the designated height, the cell picker will pick up the solar cells and transfer them to the carrier plate.
[0061] S4. After the cell transfer device moves the battery cell, the lifter 110 falls back to its initial position, and the image acquisition device 200 performs image acquisition and analysis on the lifter 110 to determine if there are any foreign objects such as fragments on the lifter 110.
[0062] S5. If foreign objects such as fragments are detected on the lifter 110, the driver 310 moves the blowing component 320 to the location of the foreign object based on the location information obtained by the image acquisition unit 200, and blows away the foreign object. After the removal is completed, the image acquisition unit 200 performs image acquisition and analysis on the lifter 110 again. If there are no foreign objects, the next battery cell delivery operation is performed; if there are still foreign objects on the lifter 110, the blowing component 320 is driven again to clean it, and an alarm signal is sent to the alarm.
[0063] S6. If no foreign objects such as fragments are found on the lifter 110, proceed directly to the next battery cell delivery operation.
[0064] In summary, this application, by installing an image acquisition device 200 on the lifting device 110, allows the image acquisition device 200 to photograph and analyze the lifting device 110 after the cell collector transfers the battery cells from the lifting device 110, thus determining the location of debris and other foreign objects. The cleaning mechanism then moves to the location of the foreign objects on the lifting device 110 based on this location information to perform cleaning. This application, by installing the image acquisition device 200 and the cleaner 300, effectively removes debris and other foreign objects from the conveying device, significantly improving production efficiency and reducing contamination of the conveyed materials.
[0065] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0066] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
