Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panels, and particularly relates to a photovoltaic array semi-finished product assembly system. Background Art

[0002] A photovoltaic panel, also known as a solar cell module, is the smallest indivisible solar cell combination device, which not only has encapsulation and internal connection, but also can provide direct current output independently. A photovoltaic panel is a kind of photo-electric semiconductor thin sheet that directly generates electricity by using sunlight, also known as a solar cell chip or a photovoltaic cell. As long as it is illuminated by light with a certain illuminance condition, it can instantaneously output voltage and generate current in the case of a loop.

[0003] In practical applications, the photovoltaic panel and the photovoltaic support need to be transported to the installation site, and the photovoltaic support needs to be installed on the pile foundation first, and then single photovoltaic panels are sequentially installed on the photovoltaic support, resulting in low installation efficiency. Summary of the Utility Model

[0004] The problem to be solved by the utility model is: how to improve the installation efficiency of photovoltaic panels.

[0005] To solve the above problems, an embodiment of the utility model provides a photovoltaic array semi-finished product assembly system, which includes:

[0006] A photovoltaic support assembly device, located at the support assembly station, for assembling photovoltaic support components;

[0007] A first transmission line, for transmitting the assembled photovoltaic support to the photovoltaic panel placement station;

[0008] A photovoltaic panel placement device, located at the photovoltaic panel placement station, for placing multiple photovoltaic panels on the assembled photovoltaic support;

[0009] A photovoltaic panel fastening device, for performing a fastening operation on the photovoltaic panels placed on the assembled photovoltaic support to form a photovoltaic array semi-finished product.

[0010] Applying the solution of the present utility model, first assemble the photovoltaic support and the photovoltaic panel into a semi-finished photovoltaic array, and then install the semi-finished photovoltaic array on the pile foundation, which can improve the installation efficiency of the photovoltaic panel. Further, after the photovoltaic support assembly device assembles the photovoltaic support components at the support assembly station, the assembled photovoltaic support is transported to the photovoltaic panel placement station by the first transmission line, and then the photovoltaic panel placement device places multiple photovoltaic panels on the assembled photovoltaic support, and then the photovoltaic panel fastening device fastens the assembled photovoltaic support and the multiple photovoltaic panels together to form a semi-finished photovoltaic array. Among them, at least one of the photovoltaic support assembly device, the photovoltaic panel placement device and the photovoltaic panel fastening device cooperates with the first transmission line, so that at least part of the assembly process of the semi-finished photovoltaic array is streamlined, thereby improving the assembly efficiency of the semi-finished photovoltaic array.

[0011] In a possible embodiment, the photovoltaic support assembly device is used to assemble the photovoltaic support components outside the first transmission line. The photovoltaic support assembly device includes an automated support assembly device for automated assembly of photovoltaic support components, or includes a pre-positioning device for the photovoltaic support components for manual assembly of the photovoltaic support components; the semi-finished photovoltaic array assembly system further includes a support transfer device for transferring the assembled photovoltaic support onto the first transmission line.

[0012] In the embodiment of the present utility model, the photovoltaic support components outside the first transmission line can be assembled in an automated or manual manner. Using an automated support assembly device can improve the automation level of the assembly line and the consistency of assembly, and there is no need to consider safety issues in the case of manual assembly. However, in the case where the operation at the support assembly station is relatively complex, the development cycle of the automated support assembly device is long and the cost is high, and it may be applicable to a photovoltaic support structure. In this case, assembling the photovoltaic support components manually can adapt to any type of photovoltaic support and has a lower cost. After the operators are familiar with the operation, the assembly efficiency can be improved. In addition, since some components of the photovoltaic support have a certain degree of flexibility and deformation ability, when using an automated support assembly device, there may be a situation where the hole positions cannot be accurately aligned and the operation stops, while the manual method can ensure the assembly stability and assembly efficiency.

[0013] In a possible embodiment, the photovoltaic support assembly device is used to assemble the photovoltaic support components on the first transmission line; the photovoltaic support assembly device includes a photovoltaic support fastening device, and the photovoltaic support fastening device is used for automated fastening of the photovoltaic support components on the first transmission line, or for following fastening of the photovoltaic support components on the first transmission line running continuously at the support assembly station under manual operation.

[0014] In this way, the step of transporting the assembled photovoltaic support to the first transmission line is omitted, which can improve the assembly efficiency of the semi-finished photovoltaic panel array. Similarly, in the embodiments of the present utility model, the components of the photovoltaic support on the first transmission line can be fastened by an automated or manual method. Using the automated method can improve the automation level of the assembly line and the consistency of fastening, and there is no need to consider the safety issues in the manual assembly method. However, in the case of relatively complex operations, fastening the components of the photovoltaic support manually can adapt to any type of photovoltaic support and has a lower cost. After the operators are familiar with the operations, the assembly efficiency can be improved; in addition, due to the fact that some components of the photovoltaic support have a certain degree of flexibility and deformation ability, there may be a situation where the automated support assembly equipment cannot accurately align the holes and stagnates, while the manual method can ensure the fastening stability and efficiency. Further, adopting the method of having the operator follow the first transmission line can reduce the waiting time at the downstream stations, speed up the rhythm of the assembly line and improve the assembly efficiency. If the operator is made to assemble in a stationary state, in order to speed up the rhythm of the production line, it is necessary to make the first transmission line run at a speed higher than the human-machine interaction safety speed after the operator has completed the assembly. In order to ensure the safety of the operator, it is necessary to provide a safety protection shell for the operator, but the comfort of the operator during the assembly operation inside the safety protection shell is extremely poor. By making the transmission line run continuously at a speed not higher than the human-machine interaction safety speed and having the operator follow the transmission line for assembly, both the assembly efficiency and the safety and comfort of the operator are ensured.

[0015] In a possible embodiment, the speed of the first transmission line at the support assembly station is not higher than the human-machine interaction safety speed, so as to provide a safe and reliable human-machine interaction environment while improving the assembly efficiency of the semi-finished photovoltaic panel array.

[0016] In a possible embodiment, there are two or more photovoltaic support assembly devices, which are respectively located at different support assembly stations to assemble the components of the photovoltaic support. The first transmission line is used to alternately transport the assembled photovoltaic supports from two or more of the photovoltaic support assembly devices to the photovoltaic panel placement station. The assembled photovoltaic supports from different photovoltaic support assembly devices can be alternately transported to the downstream stations, thereby speeding up the rhythm of the production line and improving the assembly efficiency.

[0017] In a possible embodiment, the photovoltaic panel placement device includes: at least one manipulator, arranged on at least one side of the first transmission line, for placing a plurality of photovoltaic panels on the assembled photovoltaic support. Since relatively heavy photovoltaic panels need to be placed at the photovoltaic panel placement station, using an automated method can ensure the assembly efficiency while reducing the operation risk of the operator.

[0018] In a possible embodiment, the manipulator is configured to place the photovoltaic panel on the assembled photovoltaic support in a manner of following the speed of the first transmission line.

[0019] By using the manipulator to place the photovoltaic panel in a manner of following the speed of the first transmission line, compared with the method of stopping the first transmission line and then placing the photovoltaic panel, the first transmission line can still maintain transmission at a certain speed instead of stopping. Therefore, the transmission delay caused by the stop of the first transmission line can be reduced and the assembly efficiency can be improved. In addition, making the manipulator follow the first transmission line at the same speed can reduce the difficulty of placing plate control.

[0020] In a possible embodiment, the number of the manipulators is more than two, and the more than two manipulators are arranged on both sides of the first transmission line in the direction transverse to its transmission direction. An isolation device for the manipulator is also provided at the photovoltaic panel placement station.

[0021] In a possible embodiment, the first transmission line operates in a step-by-step manner at the photovoltaic panel fastening station. The photovoltaic panel fastening device is configured to automatically fasten the photovoltaic panel placed on the assembled photovoltaic support. The photovoltaic panel fastening device is located below the photovoltaic panel placed on the assembled photovoltaic support or downstream of the photovoltaic panel placement device. By making the first transmission line operate in a step-by-step manner, the fastening difficulty can be reduced; by using an automatic fastening device for the fastening operation, the automation degree of the production line can be improved, the fastening consistency can be improved, and the risk problems in the manual fastening method do not need to be considered.

[0022] Alternatively, the first transmission line operates in a continuous manner at the photovoltaic panel fastening station. The photovoltaic panel fastening device is located downstream of the photovoltaic panel placement device and is used to tightly fasten the photovoltaic panel placed on the assembled photovoltaic support under manual operation. In the case where the photovoltaic panel fastening operation is relatively complex, the development cycle of automated equipment is long, the cost is high, and it may only be applicable to the fastening structure of a certain type of photovoltaic support and photovoltaic panel. However, using a manual method for fastening can adapt to any type of photovoltaic panel and photovoltaic support, and the cost is relatively low. After the operator becomes familiar with the operation, the fastening efficiency can be improved. Further, adopting the method of manual fastening following the first transmission line can reduce the waiting time at the next station, speed up the production line tempo, and improve the assembly efficiency of the semi-finished photovoltaic panel array. If the operator fastens the panel in a stationary state, in order to speed up the production line tempo, the first transmission line needs to run at a speed higher than the human-machine interaction safety speed after the operator finishes fastening. To ensure the safety of the operator, a safety protection shell needs to be provided for the operator. However, the comfort of the operator during the assembly operation inside the safety protection shell is extremely poor. By enabling the transmission line to run continuously at a speed not higher than the human-machine interaction safety speed and the operator follows the transmission line for fastening, both the fastening efficiency and the safety and operation comfort of the operator are ensured.

[0023] In a possible embodiment, the speed of the continuously operating first transmission line at the photovoltaic panel fastening station is not higher than the human-machine interaction safety speed. This can avoid posing a safety threat to the operator due to too fast a transmission speed, improve the safety of the operation, and provide a safe human-machine interaction environment.

[0024] In a possible embodiment, the system further includes: a photovoltaic array semi-finished product stacking device, located at the stacking station, and the photovoltaic array semi-finished product stacking device is used to stack the photovoltaic array semi-finished products.

[0025] In a possible embodiment, the first transmission line is also used to transport the photovoltaic array semi-finished products to the stacking station. The first transmission line sequentially includes: a fastening station transmission section, an acceleration transmission section, and a stacking station transmission section, and the speeds of each transmission section are independently adjustable; the fastening station transmission section is used to transport the photovoltaic array semi-finished products from the photovoltaic panel fastening station to the acceleration transmission section, the acceleration transmission section is used to accelerate the photovoltaic array semi-finished products to the stacking station transmission section at a speed greater than that of the fastening station transmission section, and the stacking station transmission section is used to transport the photovoltaic array semi-finished products to and stop at the stacking station.

[0026] The setting of the acceleration transmission section can increase the distance between two adjacent semi-finished photovoltaic arrays, so that when the downstream semi-finished photovoltaic arrays are stacked, there is no semi-finished photovoltaic array waiting to be stacked, improving the production line rhythm and stacking efficiency. When there are multiple bracket assembly stations and the assembled photovoltaic brackets are alternately transported downstream, the distance between two adjacent semi-finished photovoltaic arrays may be very small. The setting of the acceleration transmission section is particularly applicable to this situation, which can greatly accelerate the rhythm of the entire production line and the stacking efficiency of the semi-finished photovoltaic arrays.

[0027] In a possible embodiment, the system further includes: a transfer vehicle and a conveying device. The semi-finished photovoltaic array stacking device is used to stack the semi-finished photovoltaic arrays onto the transfer vehicle, and the conveying device is used to convey the transfer vehicle filled with the semi-finished photovoltaic arrays onto a transport vehicle to realize the transportation of the semi-finished photovoltaic arrays.

[0028] In a possible embodiment, the manipulator is further used to take out a photovoltaic panel from a tray loaded with photovoltaic panels and move it to a photovoltaic panel placement station. The system further includes: a second transmission line for conveying the tray loaded with photovoltaic panels to a photovoltaic panel picking station; and / or a third transmission line for discharging empty trays.

[0029] In a possible embodiment, there are two or more of the second transmission line and / or the third transmission line, which are respectively arranged on both sides of the first transmission line. Description of the Drawings

[0036] In view of the problem of low installation efficiency of photovoltaic panels in the prior art, the present utility model provides a semi-finished product assembly system for a photovoltaic array, which pre-fastens multiple photovoltaic panels on a photovoltaic bracket to form a semi-finished product of the photovoltaic array, eliminating the need for workers to first install the bracket at the photovoltaic panel installation site and then lift the photovoltaic panel onto the photovoltaic bracket, thereby improving the installation efficiency and safety. Further, by using this system, at least one of the photovoltaic bracket assembly device, the photovoltaic panel placement device, and the photovoltaic panel fastening device cooperates with the first transmission line, whereby at least partial assembly line operation of the semi-finished product of the photovoltaic array can be achieved, thus reducing the waiting time during the assembly process and improving the assembly efficiency.

[0037] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following specifically describes the specific embodiments of the present utility model in conjunction with the accompanying drawings.

[0038] An embodiment of the present utility model provides a schematic structural diagram of a semi-finished product assembly system for a photovoltaic array. The system may include: a photovoltaic bracket assembly device, a first transmission line, a photovoltaic panel placement device, and a photovoltaic panel fastening device. Among them:

[0039] The photovoltaic bracket assembly device, located at the bracket assembly station, is used for assembling the components of the photovoltaic bracket;

[0040] The first transmission line is used to transfer the assembled photovoltaic bracket to the photovoltaic panel placement station;

[0041] The photovoltaic panel placement device, located at the photovoltaic panel placement station, is used for placing multiple photovoltaic panels on the assembled photovoltaic bracket;

[0042] The photovoltaic panel fastening device is used to perform a fastening operation on the photovoltaic panels placed on the assembled photovoltaic bracket to form a semi-finished product of the photovoltaic array.

[0043] At least one of the photovoltaic bracket assembly device, the photovoltaic panel placement device, and the photovoltaic panel fastening device cooperates with the first transmission line, enabling at least partial assembly line operation of the semi-finished product of the photovoltaic array, thereby improving the assembly efficiency.

[0044] Figure 1 This is a schematic diagram of the scene at a semi-finished product assembly site for a photovoltaic array in an embodiment of the present utility model. Referring to Figure 1 , at the semi-finished product assembly site, there are successively arranged a bracket assembly station 11, a photovoltaic panel placement station 12, and a photovoltaic panel fastening station 13.

[0045] The photovoltaic support assembly device is located at the support assembly station 11 and can assemble the components of the photovoltaic support to form an assembled photovoltaic support. The first transmission line 10 can transmit the assembled photovoltaic support from the support assembly station 11 to the photovoltaic panel placement station 12. The photovoltaic panel placement device is located at the photovoltaic panel placement station 12 and can place multiple photovoltaic panels on the assembled photovoltaic support. The photovoltaic panel fastening device is located at the photovoltaic panel fastening station 13 and can perform a fastening operation on the photovoltaic panels placed on the assembled photovoltaic support, thereby forming a semi-finished photovoltaic array.

[0046] Figure 2 This is a schematic structural diagram of a photovoltaic support in an embodiment of the present invention. Referring to Figure 2 , the components of the photovoltaic support, exemplarily, may include: a support beam 21, purlins 22, and purlin brackets 23. When the photovoltaic support assembly device assembles the components of the photovoltaic support, it can first assemble and fix the support beam 21 and the purlin bracket 23, and then fix the assembled support beam 21 and purlin bracket 23 to the purlins 22 to form an assembled photovoltaic support. It can be understood that the structure of the photovoltaic support is not limited to Figure 3 shown, and it can be any suitable structure capable of fixing photovoltaic panels.

[0047] In one embodiment, the components of the photovoltaic support can be arranged in the area within the support assembly station 11 and outside the first transmission line 10. At this time, the photovoltaic support assembly device can assemble the components of the photovoltaic support outside the first transmission line 20. After assembly, the assembled photovoltaic support is then placed on the first transmission line 20.

[0048] In a specific implementation, the photovoltaic support assembly device can include automated support assembly equipment for automatically assembling the components of the photovoltaic support, or include equipment for positioning the components of the photovoltaic support, and operators can manually assemble the components of the photovoltaic support with the help of these positioning devices.

[0049] For example, the automated support assembly equipment can include: automated fastening equipment and automated clamping equipment, such as but not limited to automated bolt tightening equipment and automated clamping equipment. The automated clamping equipment and the automated bolt tightening equipment can clamp and tighten the support beam 21 and the purlin bracket 23, and can also position, clamp, and tighten the purlins 22 and the assembled support beam 21 and purlin bracket 23. The automated assembly method can improve the automation level and assembly consistency.

[0050] Another example is, as Figure 3As shown, the photovoltaic support assembly device may further include: devices for positioning the components of the photovoltaic support, such as, but not limited to, positioning slots, card slots, etc. These positioning devices provide pre-positioning of the photovoltaic components to facilitate manual assembly of the photovoltaic support components by the operator. Automated support assembly devices are relatively complex, have a long development cycle, and are costly, and can only be applied to one type of photovoltaic support structure. However, assembling the components of the photovoltaic support manually can be adapted to any type of photovoltaic support, and the cost is relatively low. After the operator is familiar with the operation, the assembly efficiency can be improved. In addition, since some components of the photovoltaic support have a certain degree of flexibility and deformation ability, there may be a situation where the automated device stalls due to inaccurate alignment of the holes, while manual assembly can ensure assembly stability and efficiency.

[0051] In some embodiments, two or more photovoltaic support assembly devices may be provided at the assembly site. Each photovoltaic support assembly device can only assemble one photovoltaic support at the same time, and two or more photovoltaic support assembly devices can assemble two or more photovoltaic supports. At this time, the assembled photovoltaic supports from two or more photovoltaic support assembly devices can be alternately placed on the first transmission line by means of the support transfer device, so that the assembled photovoltaic supports can be continuously and uninterruptedly transported to the downstream station, thereby reducing the waiting time before the downstream station performs operations and further improving the assembly efficiency.

[0052] In some embodiments, in order to shorten the length of the first transmission line and reduce the cost of the assembly system, two or more of the photovoltaic support assembly devices may be provided at least on both sides of the first transmission line. Specifically, when two or more of the photovoltaic support assembly devices are provided at the assembly site, the two or more photovoltaic support assembly devices may be distributed on both sides of the first transmission line, which facilitates the alternate placement of each photovoltaic support assembly device on the first transmission line.

[0053] Figure 3 This is a schematic diagram of the scene of the support assembly station in an embodiment of the present invention. Referring to Figure 3 , two support assembly stations symmetrically distributed on both sides of the first transmission line 10 may be provided at the assembly site, namely the first support assembly station 41 and the second support assembly station 42. A first photovoltaic support assembly device 411, such as a device for positioning the components of the photovoltaic support, is provided in the first support assembly station 41, and a second photovoltaic support assembly device 421, such as a device for positioning the components of the photovoltaic support, is provided in the second support assembly station 42. The assembled photovoltaic supports from the first photovoltaic support assembly device and the second photovoltaic support assembly device can be alternately placed on the first transmission line 20.

[0054] In some embodiments, the assembly system may further include at least one bracket transfer device configured to transfer the assembled photovoltaic bracket to the first transmission line. Specifically, the bracket transfer device may transfer the assembled photovoltaic bracket to the first transmission line by means of hoisting or translational transportation.

[0055] In some embodiments, there are more than two photovoltaic bracket assembly devices, which are respectively located at different bracket assembly stations. The more than two photovoltaic bracket assembly devices are respectively configured to assemble the photovoltaic bracket components outside the first transmission line. At this time, at least one bracket transfer device may be provided to alternately place the assembled photovoltaic brackets from the more than two photovoltaic bracket assembly devices on the first transmission line.

[0056] For example, referring to Figure 3 , the assembly system may be provided with a bracket transfer device 43, such as, but not limited to, a hoisting device. The bracket transfer device 43 may alternately place the photovoltaic brackets assembled by the first photovoltaic bracket assembly device and the second photovoltaic bracket assembly device on the first transmission line 10.

[0057] In some embodiments, referring to Figure 3 , the bracket assembly station may further be provided with an isolation device 44. The isolation device 44 may be located on at least one side of the first transmission line and is configured to isolate the first transmission line from the bracket assembly station to prevent the high-speed transportation of the first transmission line from posing a threat to the operators in the bracket assembly station.

[0058] In some embodiments, the photovoltaic bracket components may be arranged on the first transmission line. At this time, the photovoltaic bracket assembly device may be configured to assemble the photovoltaic bracket components on the first transmission line. The assembled photovoltaic brackets are directly transported to the downstream station through the first transmission line without the need to provide a bracket transfer device to transfer the assembled photovoltaic brackets, thereby reducing the assembly cost and saving the photovoltaic bracket transfer time, thus improving the assembly efficiency.

[0059] In a specific implementation, when the photovoltaic bracket components are arranged on the first transmission line, the photovoltaic bracket assembly device may further include a photovoltaic bracket fastening device. The photovoltaic bracket fastening device may automatically fasten the photovoltaic bracket components on the first transmission line, such as, but not limited to, an automatic bolt tightening device; or be configured to perform following fastening on the photovoltaic bracket components on the continuously operating first transmission line under manual operation. In this case, the photovoltaic bracket fastening device may include, for example, a wrench, an electric screwdriver, and the like.

[0060] In one embodiment, the first transmission line can be controlled to stop at the bracket assembly station, so that the photovoltaic bracket fastening device can automatically fasten the photovoltaic bracket components on the first transmission line. Thereby, while ensuring the assembly efficiency, the automation level and fastening consistency are improved. In one example, the automatic photovoltaic bracket fastening device can be arranged below the first transmission line for automatic assembly. Carrying the photovoltaic bracket components by the first transmission line can reduce costs and there is no risk of tipping over, and the automatic device can also fully contact the position to be fastened.

[0061] In another embodiment, the first transmission line can also be controlled to run at a lower speed at the bracket assembly station, so that the photovoltaic bracket fastening device can follow the first transmission line under manual operation, that is, move basically synchronously with the first transmission line, to achieve following fastening of the photovoltaic bracket components.

[0062] Specifically, at the bracket assembly station, the method of manually following the continuously running first transmission line can be adopted, and the photovoltaic bracket fastening device is used to assemble the photovoltaic bracket components on the first transmission line to obtain the assembled photovoltaic bracket. By adopting this method, the step of transporting the assembled photovoltaic bracket to the first transmission line is omitted, and the assembly efficiency of the photovoltaic panel array semi-finished product can be improved; compared with manual assembly when the first transmission line is stationary, the waiting time of the downstream station can be reduced, and the assembly efficiency of the photovoltaic panel array semi-finished product can be improved.

[0063] At this time, the running speed of the first transmission line at the bracket assembly station can be controlled to avoid posing a safety threat to the operator due to too fast transmission speed and improve the safety of operation.

[0064] In one embodiment, the speed of the first transmission line at the bracket assembly station can be set not to be higher than the human-machine interaction safety speed. At this time, the running speed of the first transmission line can ensure that the operator performs the photovoltaic bracket assembly operation in a safe environment. In the present invention, the running speed of the first transmission line 20 can be set not to be higher than 300 mm / s, so as to facilitate manual following assembly operation of the photovoltaic panel and ensure the safety of the operator.

[0065] In a specific implementation, the photovoltaic bracket components can be arranged on the first transmission line, and the method of manually following the first transmission line below the continuously running first transmission line is adopted to assemble the photovoltaic bracket components on the first transmission line to obtain the assembled photovoltaic bracket.

[0066] At this time, at the bracket assembly station, the first transmission line has a certain height. The photovoltaic bracket components can be placed on the first transmission line, and the operator can move below the first transmission line at a speed substantially the same as the running speed of the first transmission line to complete the assembly on the first transmission line. After the assembly is completed, the assembled photovoltaic bracket is directly transported to the downstream station by the first transmission line. Carrying the photovoltaic bracket components by the first transmission line can reduce costs, and there is no risk of tipping over. The operator can also fully access the positions to be fastened.

[0067] In one embodiment, multiple bracket assembly stations can be provided. That is to say, the first transmission line can have multiple branches, and photovoltaic bracket components are provided on each branch. In this way, when there are multiple bracket assembly stations, the photovoltaic bracket components on different branches of the continuously running first transmission line can be assembled by means of manual following of different branches, and multiple assembled photovoltaic brackets can be obtained. The assembled photovoltaic brackets obtained on different branches subsequently can be alternately transported to the downstream station, thereby improving the assembly efficiency.

[0068] In a specific implementation, the first transmission line can transport the assembled photovoltaic bracket to the photovoltaic panel placement station. The photovoltaic panel placement station can include at least one manipulator, arranged on at least one side of the first transmission line. The manipulator can place multiple photovoltaic panels on the assembled photovoltaic bracket, for example, horizontally on the assembled photovoltaic bracket. The use of the manipulator can realize the automatic placement of photovoltaic panels, reduce the number of operators, improve the assembly safety, and improve the assembly efficiency.

[0069] Figure 4 This is a schematic diagram of the scene of the photovoltaic panel placement station in an embodiment of the present invention. Refer to Figure 4 In a specific implementation, only one manipulator 121 can be provided in the photovoltaic panel placement station, that is, one manipulator 121 is used for placing photovoltaic panels.

[0070] In some embodiments, two or more manipulators 121 can be provided in the photovoltaic panel placement station. The two or more manipulators 121 are at least arranged on both sides of the first transmission line 10, that is, on both sides in the direction transverse to the transmission direction of the first transmission line. The specific number of the manipulators 121 can be set according to actual needs. By providing two or more manipulators 212 on both sides of the first transmission line, the semi-finished photovoltaic array finally obtained can include two or more photovoltaic panels in the direction transverse to the transmission direction of the first transmission line, which can greatly improve the installation efficiency of the photovoltaic panels. Moreover, the two or more photovoltaic panels are carried by the first transmission line in a horizontal state, without the risk of tipping over.

[0071] For example, the photovoltaic panel placement station 12 can be provided with only two manipulators 121, which are respectively located on both sides of the first transmission line 10. Thus, photovoltaic panels can be placed at different positions of the assembled photovoltaic support 211 simultaneously, thereby improving the placement efficiency of the photovoltaic panels.

[0072] Again, the photovoltaic panel placement station 12 can also be provided with more than three manipulators 121, with at least two of the manipulators located on the same side of the first transmission line 10. The manipulators located on the same side of the first transmission line 10 can be arranged along the transmission direction of the first transmission line 10. In this way, more than three manipulators 121 can simultaneously place photovoltaic panels at different positions of the assembled photovoltaic support 111, thereby improving the placement efficiency of the photovoltaic panels.

[0073] In a specific implementation, the manipulator 121 can place multiple photovoltaic panels 122 on the assembled photovoltaic support 111 in a manner of following the speed of the first transmission line 10. Here, the so-called following the speed of the first transmission line 10 means that when the manipulator 121 places the photovoltaic panel 122 above the first transmission line 10, it moves along the transmission direction of the first transmission line 10 at the same speed as the first transmission line 10, so as to follow the first transmission line 10 and maintain synchronization with the first transmission line 20, that is, to be relatively stationary with respect to the first transmission line 10. Then, the photovoltaic panel 122 is placed on the assembled photovoltaic support 111.

[0074] By using the manipulator 121 to place the photovoltaic panels in a manner of following the speed of the first transmission line 10, compared with the method of stopping the first transmission line 10 and then placing the photovoltaic panels, the first transmission line 10 can still maintain transmission at a certain speed instead of stopping. Therefore, the transmission delay caused by the stop of the first transmission line 10 can be reduced, and the assembly efficiency can be improved. In addition, making the manipulator follow the first transmission line at the same speed can reduce the difficulty of plate placement control.

[0075] In a specific implementation, when the manipulator 121 places the photovoltaic panel on the assembled photovoltaic support 111, it can complete the positioning of the photovoltaic panel with the help of a vision component (such as a camera), etc., so as to achieve precise placement.

[0076] In a specific implementation, referring to Figure 4 , the photovoltaic panel placement station 12 can also be provided with an isolation device for the manipulator 121. The isolation device for the manipulator 121 is used to isolate the manipulator from the operators in the upstream and downstream stations.

[0077] Specifically, the isolation device of the manipulator 121 may include at least one of a first isolation device 121a and a second isolation device 121b, which is used to isolate the manipulator from the operator and prevent the operation of the manipulator from posing risks to personnel, thereby providing a safe interaction environment. Among them, the first isolation device 121a is located on one side of the photovoltaic panel placement station 12 close to the bracket assembly station, and can be used, for example, to isolate the manipulator from the operator at the bracket assembly station. The second isolation device 121b is located on one side of the photovoltaic panel placement station 12 close to the photovoltaic panel fastening station, and can be used, for example, to isolate the manipulator from the operator at the photovoltaic panel fastening station. The first transmission line 20 can run under the first isolation device 121a and the second isolation device 121b.

[0078] In a specific implementation, the first isolation device 121a and the second isolation device 121b can be implemented by using wire meshes, etc., and there is no limitation here as long as they can play an isolation role.

[0079] In some embodiments, at the photovoltaic panel fastening station 13 located downstream of the photovoltaic panel placement station 12, the assembled photovoltaic bracket 111 and the multiple photovoltaic panels 122 can be fastened together by manually using a photovoltaic panel fastening device to follow the first transmission line to form a semi-finished photovoltaic array. By manually performing the photovoltaic panel fastening operation, the fastening operation can be flexibly performed on each photovoltaic panel according to the placement position of the photovoltaic panel, thereby improving the fastening efficiency. In the case where the automated fastening equipment is relatively complex, the development cycle is long, the cost is high, and it may be applicable to a type of photovoltaic bracket structure. However, by manually fastening the photovoltaic bracket and the photovoltaic panel, it can be adapted to any type of photovoltaic bracket, and the cost is low. After the operator is familiar with the operation, the assembly efficiency can be improved. Further, the method of manually following the first transmission line for fastening can reduce the waiting time at the next station, speed up the production line tempo, and improve the assembly efficiency of the semi-finished photovoltaic panel array.

[0080] In some embodiments, to ensure the safety of the operator, after the photovoltaic panel and the assembled photovoltaic bracket are transported outside the isolation device of the manipulator, the photovoltaic bracket and the photovoltaic panel are fastened by manually using a photovoltaic panel fastening device.

[0081] In specific implementation, the speed of the first transmission line at the photovoltaic panel fastening station can be controlled to avoid posing a safety threat to the operator due to the excessive speed of the first transmission line. Specifically, the speed of the first transmission line at the photovoltaic panel fastening station can be set not to exceed the human-machine interaction safety speed, thereby ensuring that the operator performs the fastening operation in a safe environment. In the present utility model, the running speed of the first transmission line 20 can be set not to exceed 300 mm / s, so as to facilitate manual following and fastening operations on the photovoltaic panel and ensure the safety of the operator.

[0082] In specific implementation, at the photovoltaic panel fastening station, the operator can follow the first transmission line below the continuously running first transmission line and use the photovoltaic panel fastening device to fasten the assembled photovoltaic support and the multiple photovoltaic panels together to form a semi-finished photovoltaic array. At this time, the first transmission line has a certain height, usually higher than the height of the operator. The operator can stand below the first transmission line and perform the fastening operation on the assembled photovoltaic support and photovoltaic panel on the first transmission line above the operator to fully contact the fastening structure of the photovoltaic support and photovoltaic panel. In addition, carrying the photovoltaic panel and the assembled photovoltaic support by the first transmission line can reduce costs and there is no risk of overturning.

[0083] In one embodiment, in order to enable the operator at the photovoltaic panel fastening station to have sufficient operation time, the photovoltaic panel fastening station can be set to include a fastening area and a manual fastening buffer area. The first transmission line enters the manual fastening buffer area through the fastening area.

[0084] Specifically, the operator usually performs the fastening operation on the assembled photovoltaic support and photovoltaic panel in the fastening area. If the fastening operation is not completed in the fastening area, the operator can move to the manual fastening buffer area following the first transmission line and continue to perform the fastening operation. If the fastening operation has been completed in the fastening area, the fastened photovoltaic support and photovoltaic panel can be transmitted to the downstream station through the manual fastening buffer area. Similarly, at the support assembly station, if the manual following and assembly method along the first transmission line is adopted, the support assembly station can also be set to include a fastening area and a manual fastening buffer area, and the first transmission line enters the manual fastening buffer area through the fastening area at the support assembly station.

[0085] By setting the manual fastening buffer area, the running time of the first transmission line at the photovoltaic panel fastening station can be increased, thereby providing sufficient operation time for the operator and preventing the photovoltaic support and photovoltaic panel from reaching the downstream station before being fastened completely.

[0086] In a specific implementation, at the photovoltaic panel fastening station 13, an automated photovoltaic panel fastening device can be used to fasten the assembled photovoltaic support 111 and the multiple photovoltaic panels 122 together to form a semi-finished photovoltaic array. In one embodiment, the photovoltaic panel fastening device can be located below the photovoltaic panels on the assembled photovoltaic support. At this time, the photovoltaic panel fastening station at least partially overlaps with the photovoltaic panel placement station. In this way, after the photovoltaic panels are placed on the photovoltaic support, the first transmission line remains stationary without transmission, and the photovoltaic panel fastening device can fasten the photovoltaic support and the photovoltaic panels.

[0087] Correspondingly, the first transmission line can be set to run in a stepping manner at the photovoltaic panel placement station and the photovoltaic panel fastening station. Here, running in a stepping manner means that the first transmission line can advance one or more positions of the photovoltaic panels at a certain speed at a time, then stop for a certain period of time, and then resume running. The photovoltaic panel fastening device can fasten the photovoltaic support and the photovoltaic panels when the first transmission line stops.

[0088] In another embodiment, referring to Figure 2 , the automated photovoltaic panel fastening device can be located downstream of the photovoltaic panel placement device. At this time, the photovoltaic panel fastening station 12 and the photovoltaic panel placement station 11 are arranged along the transmission direction of the first transmission line 10. In this way, after the photovoltaic panels are placed on the photovoltaic support, they can be transported to the photovoltaic panel fastening station 13 through the first transmission line, and then the photovoltaic panel fastening device fastens the photovoltaic support and the photovoltaic panels.

[0089] Correspondingly, the first transmission line can be set to run in a stepping manner or continuously at the photovoltaic panel placement station, and run in a stepping manner at the photovoltaic panel fastening station. At this time, at the photovoltaic panel fastening station, the photovoltaic panel fastening device can fasten the photovoltaic support and the photovoltaic panels when the first transmission line stops.

[0090] In a specific implementation, the first transmission line can be controlled to leave the photovoltaic panel fastening station at a relatively high speed. That is to say, the first transmission line is stationary at the photovoltaic panel fastening station to facilitate the automated fastening of the photovoltaic panel fastening device. Then, the first transmission line can run at a relatively fast speed, for example but not limited to, at a speed not lower than 250 mm / s. Since the photovoltaic panels and the assembled photovoltaic support are fastened by an automated fastening device rather than manually, the first transmission line can be set to leave the photovoltaic panel fastening station at a relatively fast speed without considering the risk issues of the operators, thereby improving the production line tempo and assembly efficiency.

[0091] In some embodiments, the first transmission line has a predetermined height such that the automated photovoltaic panel fastening device can perform a fastening operation on the photovoltaic panel below the photovoltaic panel placed on the first transmission line to fully contact the fastening structures of the photovoltaic support and the photovoltaic panel. In addition, carrying the photovoltaic panel and the assembled photovoltaic support by the first transmission line can reduce costs and there is no risk of tipping over.

[0092] In the embodiments of the present application, for the same semi-finished photovoltaic array, the placement of the photovoltaic panels and the fastening of the photovoltaic panels can be carried out simultaneously, that is, the placement of the photovoltaic panels and the fastening of the photovoltaic panels are carried out alternately, rather than fastening all the photovoltaic panels after they are all placed. This is especially applicable when the semi-finished photovoltaic array includes a relatively large number of photovoltaic panels. In this way, the length of the first transmission line can be shortened, the number of manipulators required for placing the photovoltaic panels can be reduced, and the efficiency of panel placement and fastening can be improved.

[0093] In specific implementation, referring to Figure 1 , the assembly site may further include a stacking station 14. Exemplarily, the stacking station 14 is a downstream station of the photovoltaic panel fastening station 13. A semi-finished photovoltaic array stacking device is provided in the stacking station 14, and the semi-finished photovoltaic array stacking device is used to stack the semi-finished photovoltaic arrays.

[0094] In specific implementation, referring to Figure 5 , the first transmission line 10 can transport the semi-finished photovoltaic array to the stacking station 14. The semi-finished photovoltaic array stacking device can stack the semi-finished photovoltaic arrays transported to the stacking station 14 into the transfer carrier 51.

[0095] At this time, the stacking station is connected to the support assembly station, the photovoltaic panel placement station, and the photovoltaic panel fastening station through the first transmission line for transmission, so that the assembly process of the semi-finished photovoltaic array is further streamlined, thereby further improving the assembly efficiency of the semi-finished photovoltaic array. In addition, using the first transmission line to transport the semi-finished photovoltaic array can simplify the transmission complexity of the semi-finished photovoltaic array and save transmission costs.

[0096] In specific implementation, for convenience of description, the area between the photovoltaic panel fastening station and the stacking station can be referred to as the accumulation station. The first transmission line successively includes a fastening station transmission section, an acceleration transmission section, and a stacking station transmission section at the photovoltaic panel fastening station, the accumulation station, and the stacking station.

[0097] Among them, the fastening station transmission section is the transmission section of the photovoltaic panel fastening station. Through the fastening station transmission section of the first transmission line, the semi-finished photovoltaic array can be transported from the photovoltaic panel fastening station to the accumulation station, that is, the acceleration transmission section of the first transmission line.

[0098] The acceleration transmission section of the first transmission line is located between the fastening station transmission section and the stacking station transmission section of the first transmission line, and is used to transmit the photovoltaic array semi-finished product to the stacking station transmission section of the first transmission line at a speed greater than that of the fastening station transmission section, so that the photovoltaic array semi-finished product transmitted by the fastening station transmission section can be accelerated to quickly detach from the photovoltaic panel fastening station, thereby keeping a distance from the unfinished or assembled photovoltaic array semi-finished products upstream. The setting of the acceleration transmission section can increase the distance between two adjacent photovoltaic array semi-finished products, so that when the downstream photovoltaic array semi-finished products are stacked, there are no photovoltaic array semi-finished products waiting to be stacked, thereby improving the stacking efficiency.

[0099] The stacking station transmission section of the first transmission line is used to transmit the photovoltaic array semi-finished product to and stop it at the stacking station. The running speed of the stacking station transmission section of the first transmission line can be lower than the running speed of the acceleration transmission section of the first transmission line. By reducing the speed, the photovoltaic array semi-finished product can be accurately placed at the stacking station.

[0100] By dividing the first transmission line into three transmission sections with independently adjustable speeds, the photovoltaic array semi-finished products can be accumulated on the first transmission line by controlling the speed of each transmission section, and can be accurately placed on the stacking station, thereby facilitating continuous stacking operations at the stacking station, thereby further improving the stacking efficiency.

[0101] In some embodiments, the accelerated transmission section is further provided with an accelerated transmission section isolation device. By providing the accelerated transmission section isolation device, the accelerated transmission section of the first transmission line can be isolated from the outside, for example, from the operator of the photovoltaic panel fastening station, to avoid safety threats to external personnel due to the excessive speed of the accelerated transmission section, thereby improving assembly safety.

[0102] In some embodiments, the stacking station 14 may provide two placement positions, one for placing the first transfer carrier 51 and the other for placing the second transfer carrier 52. The first transfer carrier 51 may be across the first transmission line 10 for stacking the photovoltaic array semi-finished products that are about to be transmitted. The second transfer carrier 52 may be used as a backup stacking device. After the first transfer carrier 51 is fully loaded with the photovoltaic array semi-finished products, the second transfer carrier 52 is moved to the first transmission line 10, thereby reducing the stacking waiting time.

[0103] In a specific implementation, before the semi-finished photovoltaic array is transferred to the stacking station 14, the transfer vehicle can be transported to the assembly site, and the number of semi-finished photovoltaic arrays that can be stacked in each transfer vehicle is greater than 1. Specifically, the transfer vehicle can be transported to the assembly site by hoisting. During the hoisting process, the target position of the transfer vehicle can be located with the help of a positioning system to achieve precise placement.

[0104] In specific implementations, there can be various types of the semi-finished product stacking devices for the photovoltaic array, which are not limited here. For example, the semi-finished product stacking device for the photovoltaic array can be located above the transfer vehicle. When the semi-finished product of the photovoltaic array is transported to the stacking station, the semi-finished product stacking device for the photovoltaic array can grab the semi-finished product of the photovoltaic array and stack the grabbed semi-finished product of the photovoltaic array into the transfer vehicle from above the transfer vehicle.

[0105] In one embodiment, the semi-finished product stacking device for the photovoltaic array can be located below the transfer vehicle and has an automatic lifting function. Specifically, referring to Figure 6 , multiple semi-finished product stacking devices 61 can be provided. Before the arrival of the photovoltaic array product, the semi-finished product stacking devices 61 can be located below the first transmission line 10. When the photovoltaic array product arrives, the semi-finished product stacking devices 61 can rise from below the first transmission line 10 until they contact the semi-finished product of the photovoltaic array. Each semi-finished product stacking device 61 is used to support different positions of the semi-finished product of the photovoltaic array, so as to realize the loading of the semi-finished product of the photovoltaic array. After the loading is completed, all the semi-finished product stacking devices 61 rise synchronously into the transfer vehicle and stack the semi-finished products of the photovoltaic array from top to bottom.

[0106] In specific implementations, referring to Figure 5 , the assembly system can further include a transfer vehicle (such as the first transfer vehicle 51 and the second transfer vehicle 52) and a conveying device 15. The semi-finished product stacking device for the photovoltaic array is used to stack the semi-finished product of the photovoltaic array onto the transfer vehicle, and the conveying device is used to convey the transfer vehicle filled with the semi-finished product of the photovoltaic array onto the transport vehicle 16 to realize the transportation of the semi-finished product of the photovoltaic array.

[0107] In specific implementations, by way of example, the first transmission line 10 stops after transporting the semi-finished product of the photovoltaic array below the transfer vehicle. When the stacking of the semi-finished product of the photovoltaic array is completed, the first transmission line 10 continues to operate to complete the transportation of the next semi-finished product of the photovoltaic array until the transfer vehicle is full. After the transfer vehicle is full, the conveying device 15 can hoist the entire transfer vehicle onto the transport vehicle 16 (as shown in Figure 5 ) for transportation by the transport vehicle 16 to realize the transportation of the semi-finished product of the photovoltaic array. Among them, there are various choices for the transport vehicle 16, such as semi-trailers, full-trailers, special vehicles, etc.

[0108] In some embodiments, the conveying device 15 can also be used to place the empty semi-finished product stacking device at the stacking station 14. In addition, the conveying device 15 is not limited to a hoisting device and can also be any other suitable device that can realize the transfer function.

[0109] In some embodiments, referring toFigure 4 At the assembly site, a photovoltaic panel picking station 17 may also be provided. A second conveyor line 171 may be provided in the photovoltaic panel picking station 17. The second conveyor line 171 is used to convey a pallet 172 loaded with photovoltaic panels to the photovoltaic panel picking station 17. Correspondingly, the manipulator 121 is also used to take out the photovoltaic panels from the pallet 172 loaded with photovoltaic panels and move them to the photovoltaic panel placing station 12.

[0110] In a specific implementation, before using the manipulator 121 to place the photovoltaic panels on the assembled photovoltaic support, the second conveyor line 171 can be used to convey the pallet 172 loaded with photovoltaic panels to the photovoltaic panel picking station 17 first, so that the manipulator can take out the photovoltaic panels from the pallet 172 loaded with photovoltaic panels at the photovoltaic panel picking station 17 and move them to the photovoltaic panel placing station 13.

[0111] In a specific implementation, the second conveyor line 171 can sequentially convey several pallets 172 loaded with photovoltaic panels to the photovoltaic panel picking station. Each pallet 172 is loaded with a plurality of regularly arranged photovoltaic panels. From the side close to the first conveyor line 10 to the side far from the first conveyor line 10, they are the first photovoltaic panel, the second photovoltaic panel, the third photovoltaic panel, and so on. At the photovoltaic panel picking station, the manipulator takes out the first photovoltaic panel from the pallet in the order of distance and moves it to the photovoltaic panel placing station 22, places it on the assembled photovoltaic support 111, then the manipulator moves to the photovoltaic panel picking station again, takes out the second photovoltaic panel from the pallet and moves it to the photovoltaic panel placing station 12, places it on the assembled photovoltaic support 111, then, the manipulator moves to the photovoltaic panel picking station again, takes out the third photovoltaic panel from the pallet and moves it to the photovoltaic panel placing station 12, places it on the assembled photovoltaic support 111, and so on. Repeat multiple times until all the photovoltaic panels in the pallet are taken out. At this time, the pallet is an empty pallet.

[0112] By providing the photovoltaic panel picking station 17 and the second conveyor line 171, the transportation and taking out of the pallets loaded with photovoltaic panels can be realized in a pipeline manner, thereby reducing the time required to take out the photovoltaic panels, and further improving the assembly efficiency.

[0113] In a specific implementation, referring to Figure 4 The second conveyor line 171 can be two or more, and are respectively arranged on both sides of the first conveyor line 10. Correspondingly, the number of photovoltaic panel picking stations 27 can be two, and are respectively arranged on both sides of the first conveyor line 20. A second conveyor line 171 is provided in each photovoltaic panel picking station 27, so as to facilitate the manipulators on both sides of the first conveyor line 10 to take out the photovoltaic panels from the photovoltaic panel picking stations 17 on their respective sides.

[0114] In some embodiments, referring to Figure 4 , the assembly system may further include a third transfer line 173 for discharging empty pallets.

[0115] Specifically, the number of the third transfer lines 173 may be more than two, which are respectively arranged on both sides of the first transfer line 10 and connected to the second transfer lines 171 on the same side, and are respectively used for discharging the empty pallets 174 generated on the second transfer lines 171 on the same side. This can avoid the empty pallets 174 from hindering the flow of non-empty pallets (i.e., pallets 172), making the pallet flow smoother, and thus can further improve the assembly efficiency.

[0116] In a specific implementation, the third transfer line 173 can discharge the empty pallets in a direction away from the first transfer line, so that the pallet flow is smoother.

[0117] After the manipulator takes out the photovoltaic panel, it can place the photovoltaic panel on the assembled photovoltaic support, and transfer it to the downstream photovoltaic panel fastening station, accumulation station and stacking station through the first transfer line, and complete the corresponding operations at the corresponding stations.

[0118] As can be seen from the above, the assembly system of the present invention can quickly assemble the components of the photovoltaic support at the assembly site by setting the photovoltaic support assembly device, the photovoltaic panel placement device can quickly place the photovoltaic panel, and the photovoltaic panel fastening device can quickly fasten the photovoltaic panel and the assembled support. Each device of the entire photovoltaic panel assembly system is arranged in a production line and is fully automated for automatic assembly, which can reduce the waiting time at each station, thereby improving the assembly efficiency of the photovoltaic panel.

[0119] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention should be determined by the scope defined by the claims.
