Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0028] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0029] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.
[0033] Silicon wafers, as the basic material for photovoltaic modules, are typically manufactured through multiple vapor deposition processes. During silicon wafer fabrication, a basket, acting as a carrier, is used to transfer the wafers between different processes via an AGV (Automated Guided Vehicle) cart. For example, after chemical vapor deposition (CVD), the CVD unloading equipment moves the basket filled with wafers to the unloading port via an internal transfer mechanism (such as a conveyor belt or robotic arm). At this point, the AGV has arrived at the CVD unloading equipment, and its platform is aligned with the unloading port. The internal transfer mechanism of the CVD unloading equipment then smoothly places the basket onto the AGV's platform. The AGV then transfers the basket to the PVD (Physical Vapor Deposition) loading equipment according to a pre-planned path. When the AGV arrives at the PVD loading equipment, the AGV's carrying platform connects with the PVD loading equipment's inlet. Then, the AGV's unloading mechanism (such as a conveyor belt) unloads the basket onto the PVD loading equipment's inlet conveyor belt, thus completing the transfer of the basket between the CVD unloading equipment and the PVD loading equipment.
[0034] However, existing AGV transport routes are long, transport time is high, equipment utilization is low, and turnover baskets are used extensively.
[0035] In this regard, on the one hand, one embodiment of this application provides a basket transfer mechanism that can be applied in the wafer field or the photovoltaic module field. It connects upstream and downstream equipment and can transfer silicon wafers between different processes or different equipment, such as transferring silicon wafers between different vapor deposition processes.
[0036] like Figure 1 and Figure 2 As shown, the flower basket transfer mechanism 10 may include a double-layer flower basket track assembly 100, an upstream lifting assembly 200, and a downstream lifting assembly 300. The double-layer flower basket track assembly 100 has a first flower basket inlet position, an upstream unloading position, and a first flower basket outlet position arranged vertically in sequence on the side near the upstream equipment, and a second flower basket inlet position, a downstream loading position, and a second flower basket outlet position arranged vertically in sequence on the side near the downstream equipment. The double-layer flower basket track assembly includes a first flower basket track and a second flower basket track spaced apart vertically. The basket conveyor system includes a first basket conveyor track that transports basket 20 from the first exit position to the second entry position, and a second basket conveyor track that transports basket 20 from the second exit position to the first entry position. An upstream lifting assembly 200, located near the upstream equipment, transports basket 20 to the first entry position, the upstream unloading position, and the first exit position. A downstream lifting assembly 300, also located near the upstream equipment, transports basket 20 to the second entry position, the downstream loading position, and the second exit position. It should be noted that... Figure 1 The square structure in the image represents the flower basket number 20.
[0037] The following description uses the transfer of the basket 20 between the chemical vapor deposition (CVD) and physical vapor deposition (PVD) processes as an example to illustrate the transfer process of the basket transfer mechanism 10. The upstream equipment includes a CVD unloading device, and the downstream equipment includes a PVD loading device. The structures of the upstream lifting assembly 200 and the downstream lifting assembly 300 can be the same as the lifting mechanisms in the CVD unloading device or the PVD loading device; for example, they can be configured as a screw conveyor structure or a belt conveyor structure.
[0038] When the CVD unloading equipment is unloading, the upstream lifting assembly 200 has already transported the basket 20 to the upstream unloading position, at which point the CVD unloading equipment inserts wafers into the basket 20. Once the basket 20 is full, the upstream lifting assembly 200 transports the basket 20 to the first exit basket position, and the first basket track of the double-layer basket track assembly 100 transports the full basket 20 from the first exit basket position to the second entry basket position. When the full basket 20 reaches the second entry basket position, the downstream lifting assembly 300 transports the full basket 20 to the downstream loading position, and the PVD loading equipment extracts wafers from the full basket 20. After all the silicon wafers in the basket 20 have been extracted, the downstream lifting assembly 300 transports the empty basket 20 to the second exit basket position, and the second basket track transports the empty basket 20 from the second exit basket position to the first entry basket position. Once the empty basket 20 reaches the first loading position, the upstream lifting component 200 transports the empty basket 20 to the upstream unloading position, facilitating unloading by the subsequent CVD unloading equipment. The basket 20 can repeat the above operation to form a closed-loop conveying system between the CVD unloading equipment and the PVD loading equipment. During normal production, as long as the number of empty baskets 20 is greater than 10, the baskets 20 can be reused, reducing the number of baskets 20 that need to be turned over.
[0039] As can be seen, the flower basket transfer mechanism 10 provided in this application, through the cooperation of the double-layer flower basket track assembly 100 and the upstream and downstream lifting assemblies 300, can eliminate the step of AGV trolley transporting flower basket 20, simplify the transportation problem of silicon wafers between different processes or different equipment, and can connect upstream and downstream equipment together, for example, to realize the integration of CVD to PVD production lines, thereby reducing the use of workshop space; in addition, it can also enable the flower basket 20 to form a closed loop of transportation between different processes or different equipment, so that the flower basket 20 can be recycled, reducing the number of times the flower basket 20 is turned over.
[0040] In some embodiments of this application, the first inlet basket position is located below the first outlet basket position, the second inlet basket position is located above the second outlet basket position, and the first basket track is located above the second basket track. When the CVD unloading equipment unloads material, the full basket 20 can be conveyed through the upper first basket track to the second inlet basket position near the PVD loading equipment; when the PVD loading equipment loads material, the empty basket 20 is conveyed through the lower second basket track to the first inlet basket position near the CVD unloading equipment. When the empty basket 20 is being conveyed by the second basket track, it can be moved for maintenance, or, according to production needs, empty baskets 20 can be added to or the number of empty baskets 20 can be reduced in the second basket track. Thus, by setting the positional relationships between the first inlet basket position and the first outlet basket position, between the second inlet basket position and the second outlet basket position, and between the first basket track and the second basket track, it is convenient to manually replenish or maintain the baskets 20.
[0041] Of course, in some other embodiments, the first flower basket inlet is located above the first flower basket outlet, the second flower basket inlet is located below the second flower basket outlet, and the first flower basket runway is located below the second flower basket runway. In this configuration, the upper first flower basket runway carries empty flower baskets 20, while the lower second flower basket runway carries full flower baskets 20.
[0042] like Figure 1 As shown in some embodiments of this application, the side of the first basket track near the upstream equipment has a first basket rotation station 100b, which is close to the first basket exit position. Since the inserting direction of the CVD unloading device is consistent with the pulling direction of the PVD loading device, when the full basket 20 reaches the first basket exit position from the upstream unloading position, it can first enter the first basket rotation station 100b for rotation, for example, rotation of 180°, to adjust the opening direction of the basket 20 so that the opening direction of the basket 20 faces the PVD loading device.
[0043] The first flower basket track is equipped with a first flower basket rotating assembly 500 at the first flower basket rotating station 100b. For example... Figure 3 As shown, the first flower basket rotating assembly 500 may include a flower basket platform 520 and a drive unit 510. The flower basket platform 520 is used to place the flower basket 20, and the drive unit 510 is capable of driving the flower basket platform 520 to rotate. The drive unit 510 may be a rotary motor or other driving mechanism, and this application does not impose specific limitations on it.
[0044] Furthermore, such as Figure 1 As shown, the first basket conveyor track has multiple basket conveyor channels 100a arranged side by side. A first upstream transfer device 110 is located on the side of the first basket conveyor track closest to the upstream equipment. The first upstream transfer device 110 can transport baskets 20 from the first basket rotation station 100b to the corresponding basket conveyor channel 100a. The first upstream transfer device 110 can transport the rotated baskets 20 to the corresponding basket conveyor channels 100a, facilitating the scheduling of baskets 20 and ensuring the orderly and stable operation of the entire CVD-PVD production line.
[0045] The structure of the first upstream transfer 110 can be the same as the transfer module of the basket 20 conveyor in the CVD unloading equipment, for example, it can be configured as a structure in which a linear motor and a slide rail cooperate.
[0046] The first basket conveying channel 100a can be equipped with a conveying mechanism, such as a belt conveyor. The number of first basket conveying channels 100a can be 2 to 4, for example, 2, 3, or 4. Each first basket conveying channel 100a can simultaneously accommodate 4 to 5 baskets 20. Setting the first basket conveying channels 100a to 2 to 4 allows for the turnover of baskets 20 between the CVD unloading equipment and the PVD loading equipment.
[0047] See also Figure 1 The first basket runway has a first basket temporary storage position 100c on the side near the downstream equipment, which is close to the second basket inlet position. A second downstream transfer unit 120 is also located on the side of the first basket runway near the downstream equipment. The second downstream transfer unit 120 can transport baskets 20 from the first basket temporary storage position 100c to the second basket inlet position. When the production capacities of the CVD and PVD equipment are not synchronized, or due to other reasons causing the feeding frequency of the CVD unloading equipment to be greater than the feeding frequency of the PVD loading equipment, there are not enough second basket inlet positions to accommodate baskets 20. In this case, the second downstream transfer unit 120 can first transport the full baskets 20 transported from the first basket runway to the first basket temporary storage position 100c for temporary storage. Then, when there are extra second basket inlet positions, the full baskets 20 in the first basket temporary storage position 100c slide into the second basket inlet position. The full flower basket 20 slides from the first flower basket temporary storage position 100c into the second flower basket position, which can be achieved by a conveying mechanism combining a linear motor and a slide rail.
[0048] The structure of the second downstream transfer 120 is the same as that of the first upstream transfer 110.
[0049] The flower basket transfer mechanism 10 also includes a second sensor, which is used to detect the lifting position and basket loading status of the downstream lifting assembly 300. When there are extra second flower basket positions, if the second sensor detects that the downstream lifting assembly 300 has been transported to the second flower basket position but is not loaded with a basket, the full flower basket 20 will slide from the first flower basket temporary storage position 100c into the second flower basket position under the drive of the conveying mechanism. The second sensor can be a camera module, which can take pictures of the downstream lifting assembly 300 to obtain its lifting position and basket loading status. Alternatively, the second sensor can be a combination of a weight sensor and an infrared sensor, where the weight sensor is used to obtain the basket loading status of the downstream lifting assembly 300, and the infrared sensor is used to obtain its lifting position.
[0050] In some embodiments of this application, the side of the second basket track near the downstream equipment has a second basket rotation station, which is close to the second basket exit position. Since the inserting direction of the CVD feeding device is consistent with the withdrawing direction of the PVD feeding device, when an empty basket 20 arrives at the second basket exit position from the downstream feeding position, it can first enter the second basket rotation station for rotation, for example, rotation of 180°, to adjust the opening direction of the basket 20 so that the opening direction of the basket 20 faces the CVD feeding device.
[0051] The second flower basket track is equipped with a second flower basket rotating assembly at the second flower basket rotating station. The second flower basket rotating assembly can have the same structure as the first flower basket rotating assembly 500.
[0052] Furthermore, the second basket conveyor track has multiple parallel second basket conveyor channels. A first downstream transfer device is located on the side of the second basket conveyor track closest to the downstream equipment. This first downstream transfer device can transport the basket 20 from the second basket rotation station to the corresponding second basket conveyor channel. The first downstream transfer device can transport the rotated basket 20 to the corresponding second basket conveyor channel, facilitating the scheduling of the basket 20 and ensuring the orderly and stable operation of the entire CVD-PVD production line.
[0053] The first downstream transfer can have the same structure as the first upstream transfer 110.
[0054] The conveying method of the second basket conveyor channel is the same as that of the first basket conveyor channel 100a. The number of second basket conveyor channels is 2 to 4, for example, it can be set to 2, 3 or 4. Each second basket conveyor channel can accommodate 4 to 5 baskets 20 at the same time. Setting the second basket conveyor channels to 2 to 4 can realize the turnover of baskets 20 between the CVD unloading equipment and the PVD loading equipment.
[0055] The second basket conveyor track has a second basket temporary storage position on the side closest to the upstream equipment, which is adjacent to the first basket entry position. The first basket conveyor track has a second upstream transfer mechanism on the side closest to the upstream equipment, capable of transporting baskets 20 from the second basket conveyor track to the second basket temporary storage position. When the production capacities of the CVD and PVD equipment are not synchronized, or due to other reasons causing the feeding frequency of the CVD unloading equipment to be lower than the feeding frequency of the PVD loading equipment, there are not enough first basket entry positions to accommodate baskets 20. In this case, the second upstream transfer mechanism can first transport empty baskets 20 from the second basket conveyor track to the second basket temporary storage position for temporary storage. Later, when there are extra first basket entry positions, the empty baskets 20 in the second basket temporary storage position slide into the first basket entry position. The sliding of empty baskets 20 from the second basket temporary storage position into the first basket entry position can be achieved through a conveying mechanism combining a linear motor and a slide rail.
[0056] The second upstream transfer and the second downstream transfer 120 have the same structure.
[0057] The flower basket transfer mechanism 10 also includes a first sensor, which is used to detect the lifting position and basket loading status of the upstream lifting assembly 200. When there are extra first flower basket loading positions, if the first sensor detects that the upstream lifting assembly 200 has been transported to the first flower basket loading position and there is no basket loaded in the upstream lifting assembly 200, the empty flower basket 20 will slide from the second flower basket temporary storage position into the first flower basket loading position under the drive of the conveying mechanism. The first sensor may have the same structure as the second sensor.
[0058] When one of the CVD or PVD equipment malfunctions, in order to ensure the other continues to operate, such as... Figure 1 and Figure 2 As shown, in one embodiment, the flower basket transfer mechanism 10 further includes an auxiliary support component 400. The auxiliary support component 400 is disposed on at least one side of the double-layer flower basket track assembly 100 and is movable between the first flower basket track and the second flower basket track. The auxiliary support component 400 has a flower basket placement position 400a. When the CVD equipment malfunctions, the auxiliary support component 400 can be raised and lowered to the second flower basket track to receive the empty flower basket 20. If the second flower basket track is located below the first flower basket track, the empty flower basket 20 can be directly transferred to other normally unloading CVD unloading equipment. However, if the second flower basket track is located above the first flower basket track, the empty flower basket 20 needs to be lowered to the first flower basket track before being transferred. When a PVD device malfunctions, the auxiliary support assembly 400 can be raised and lowered to the first basket track to receive a full basket 20. If the first basket track is above the second basket track, the full basket 20 must be lowered to the second basket track before being transferred to another normally operating PVD loading device. If the first basket track is below the second basket track, the full basket 20 can be transferred directly. The auxiliary support assembly 400 ensures high production efficiency in the CVD-PVD production process and minimizes losses.
[0059] The auxiliary load-bearing component 400 can be lifted or lowered by a lifting mechanism, which can be a screw structure or other conveying mechanism.
[0060] The auxiliary support component 400 can be configured as one or more. Figure 1 and Figure 2 Two are shown. When there are two auxiliary support components 400, these two auxiliary support components 400 can be located on opposite sides of the double-layer flower basket track component 100, and these two auxiliary support components 400 can be used to support a full flower basket 20 or an empty flower basket 20 at the same time, or one auxiliary support component 400 is used to support a full flower basket 20 and the other auxiliary support component 400 is used to support an empty flower basket 20.
[0061] On the other hand, one embodiment of this application also provides a photovoltaic module manufacturing system, which includes upstream equipment, downstream equipment, and a flower basket transfer mechanism 10 as described in any of the above claims, wherein the flower basket transfer mechanism 10 is connected between the upstream equipment and the downstream equipment.
[0062] As described above, the photovoltaic module manufacturing system, through the cooperation of the double-layer basket track component 100 of the basket transfer mechanism 10 and the upstream and downstream lifting components 300, can eliminate the step of AGV trolley transporting basket 20, simplifying the transportation of silicon wafers between different processes or different equipment, and connecting upstream and downstream equipment together, for example, realizing the integration of CVD to PVD production lines, thereby reducing the use of workshop space; in addition, it can also make the basket 20 form a closed-loop transport between different processes or different equipment, so that the basket 20 can be recycled, reducing the number of baskets 20 turnovers.
[0063] In some embodiments of this application, the upstream equipment includes a CVD unloading device, and the downstream equipment includes a PVD loading device. This allows the basket 20 to be transferred between the CVD and PVD processes.
[0064] 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.
[0065] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent 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. Therefore, the protection scope of this patent application should be determined by the appended claims.
