Description

Technical Field

[0001] This invention relates to the field of battery equipment technology, and in particular to a photovoltaic module arrangement device, a photovoltaic module production system, a photovoltaic module arrangement method, and a photovoltaic module production method. Background Technology

[0002] In the production of photovoltaic modules, from the arrival of silicon wafers and glass to the completion of full-format silicon wafer welding, the process involves equipment and processes such as string welding machines, stacking machines, and end welding machines. First, the solar cells are removed from the material box and arranged using vision and robotic compensation for handling. Then, the cells are connected in series using infrared welding ribbons. Next, the stacking machine arranges multiple strings of cells according to requirements, and the end welding machine welds the busbars to the strings, achieving full-format display processing. After the upper components are laid, the modules flow to the subsequent testing and lamination equipment.

[0003] Currently, in the photovoltaic module production process, the cells undergo at least 5 transfers from feeding to end welding, and at least 3 transfers after being welded into a string. Since silicon wafers are fragile, these transfers, especially after being welded into a string, greatly increase the breakage rate of the modules.

[0004] Therefore, how to improve the yield rate of component production lines and the production continuity of production lines is an urgent problem to be solved by personnel in this technical field. Summary of the Invention

At the solder ribbon loading station, multiple solder ribbons are arranged on the substrate assembly along a second direction perpendicular to the first direction.

[0086] Optionally, in the above photovoltaic module arrangement method, in the step of arranging the plurality of solar cells and the plurality of solder ribbons on the substrate module,

[0087] The support unit includes a first movable support unit and a second movable support unit.

[0088] The first moving support unit drives the substrate assembly to pass through the solder ribbon loading station corresponding to the solder ribbon loading unit along the first direction.

[0091] Input the lower rigid plate and the lower flexible layer to form a substrate assembly;

[0099] As can be seen from the above technical solution, the photovoltaic module arrangement device provided by the present invention combines a lower rigid plate and a lower flexible layer to form a substrate module. Since the cell loading unit and the ribbon loading unit can move relative to the substrate module carried by the support unit, multiple cells output by the cell loading unit and multiple ribbons output by the ribbon loading unit can complete the arrangement of the photovoltaic module during the relative movement with the substrate module, effectively utilizing space and time. During this process, the cells and ribbons are directly arranged on the substrate module so that the arranged ribbons and cells can be directly welded on the substrate module for subsequent operations (such as lamination). In this process, there is no need to handle the cells again, effectively avoiding the probability of cell breakage, reducing the breakage rate, and improving the yield of the module production line. Furthermore, since the cell loading unit and the ribbon loading unit can move relative to the substrate module carried by the support unit, continuous arrangement of cells and ribbons can be achieved, realizing production continuity on the production line.

[0111] This invention discloses a photovoltaic module arrangement device to improve the yield and production continuity of the module production line. This invention also provides a photovoltaic module production system, a photovoltaic module arrangement method, and a photovoltaic module production method.

[0112] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0113] like Figures 1-9 As shown, this embodiment of the invention provides a photovoltaic module arrangement device, including a support unit, a cell loading unit, and a ribbon loading unit. The support unit is used to support a substrate assembly, which includes a lower rigid plate and a lower flexible layer; the cell loading unit is used to move multiple cells to corresponding positions on the substrate assembly, and the cell loading unit is movable relative to the substrate assembly supported by the support unit; the ribbon loading unit is used to move multiple ribbons to corresponding positions on the substrate assembly, and the ribbon loading unit is movable relative to the substrate assembly supported by the support unit.

[0114] The photovoltaic module arrangement device provided in this invention combines a lower rigid plate and a lower flexible layer to form a substrate module. Since the cell loading unit and the ribbon loading unit can move relative to the substrate module carried by the support unit, the multiple cells output by the cell loading unit and the multiple ribbons output by the ribbon loading unit can complete the arrangement of the photovoltaic module during their relative movement with the substrate module, effectively utilizing space and time. During this process, the cells and ribbons are directly arranged on the substrate module, allowing for direct welding and subsequent operations (such as lamination) on the substrate module. This eliminates the need for repeated handling of the cells, effectively reducing the chance of cell breakage, lowering the breakage rate, and improving the yield of the module production line. Furthermore, because the cell loading unit and the ribbon loading unit can move relative to the substrate module carried by the support unit, continuous arrangement of cells and ribbons can be achieved, ensuring production continuity on the production line.

[0115] In this embodiment, the lower rigid plate can be a glass substrate, and the lower flexible layer can be a laminate commonly used in the field of solar cells, such as EVA (ethylene-vinyl acetate copolymer) or POE (polyolefin elastomer).

[0116] To simplify the layout of the photovoltaic module arrangement device while allowing relative movement between the substrate assembly carried by the support unit and the cell loading unit and the ribbon loading unit, preferably, the support unit is capable of moving the substrate assembly. That is, the main structures of the support unit, the cell loading unit, and the ribbon loading unit can be relatively fixed, reducing energy consumption.

[0117] Of course, the carrier unit can also function solely as a support platform for the substrate assembly, while the cell loading unit and the ribbon loading unit can move relative to the carrier unit. For example, a slide rail can be provided along the extension direction of the carrier unit, allowing the cell loading unit and the ribbon loading unit to slide on the slide rail; or, pulleys can be provided at the bottom of the cell loading unit and the ribbon loading unit, allowing them to slide along the extension direction of the carrier unit. This enables the cell loading unit to move relative to the substrate assembly carried by the carrier unit and the ribbon loading unit to move relative to the substrate assembly carried by the carrier unit.

[0118] The support unit is capable of moving the substrate assembly a predetermined distance within a unit time. That is, the support unit is a mobile support unit capable of moving the substrate assembly a predetermined distance within a unit time. The support unit is a mobile support unit capable of moving in a stepwise manner (moving the substrate assembly a unit distance after a certain time interval) or continuously (moving a predetermined distance continuously within a unit time).

[0119] The carrier unit moves the substrate assembly along a first direction, passing through a cell loading station and a ribbon loading station. The cell loading station is where the cell loading unit moves the cells onto the substrate assembly, and the ribbon loading station is where the ribbon loading unit moves the ribbons onto the substrate assembly. These stations allow multiple cells and ribbons moving in rows onto the substrate assembly to be arranged along a second direction perpendicular to the first direction. It is understood that the number of cells delivered by the cell loading unit to the substrate assembly through the cell loading station per unit time should meet the arrangement requirements of cells at a predetermined distance on the substrate assembly. Similarly, the number of ribbons delivered by the ribbon loading unit to the substrate assembly through the ribbon loading station per unit time should meet the arrangement requirements of ribbons at a predetermined distance on the substrate assembly. Here, the predetermined distance is N times the cell placement size, where N ≥ 1; the cell placement size is the spacing between the preceding and following cells. In this embodiment, the specific value of N can be determined based on the actual number of input battery cells in the battery cell loading unit and the predetermined distance, and is not specifically limited here. Of course, it can also be determined based on other predetermined distances, which are not specifically limited here and are all within the protection range.

[0120] Taking a predetermined spacing of one times the cell arrangement size as an example, a photovoltaic module arrangement device is described as follows: A support unit drives the substrate module to move along a first direction; a moving support unit drives the substrate module to move by one times the cell arrangement size. At the cell loading station, a cell loading unit loads multiple spaced cells into the substrate module in a second-direction arrangement. At the ribbon loading station, a ribbon loading unit loads multiple spaced ribbons into the substrate module in a second-direction arrangement. The support unit continues to drive the substrate module to move along the first direction by one times the cell arrangement size. The cell loading unit and the ribbon loading unit load another row of cells and ribbons at their respective cell loading and ribbon loading stations. The support unit continues to drive the substrate module to move along the first direction until it has completely passed the cell loading and ribbon loading stations, at which point the cells and ribbons are arranged in an array on the substrate module. By moving the substrate assembly in a direction perpendicular to the arrangement direction of the solar cells or solder ribbons when they are loaded onto the substrate assembly, multiple solar cells and solder ribbons can be arranged into a photovoltaic module during their relative movement with the substrate assembly, effectively utilizing space and time and improving work efficiency.

[0121] The carrier unit can move continuously or in a step-by-step manner; preferably, it is a step-by-step moving carrier unit. Step-by-step movement can achieve better layout accuracy.

[0122] The supporting unit can be a conveyor belt, conveyor rollers, or air-bearing support plate and conveying mechanism. The power transmission device of the above-mentioned supporting unit can be a gear and rack, or a linear motor.

[0123] Specifically, the support unit can drive the substrate assembly to move in steps, moving a row of solar cells and a row of solder ribbons towards the substrate assembly at each step of a preset distance. Alternatively, the support unit can drive the substrate assembly to move continuously, moving a row of solar cells and a row of solder ribbons towards the substrate assembly at the same speed as the substrate assembly at each preset distance of movement.

[0124] Corresponding to the first direction, the cell loading unit can be positioned before the ribbon loading unit, so that when arranged on the substrate assembly, the cells are arranged on the substrate assembly and the ribbons are arranged on the cells. Alternatively, the ribbon loading unit can also be positioned before the cell loading unit, so that when arranged on the substrate assembly, the ribbons are arranged on the substrate assembly and the cells are arranged on the ribbons. The relative positions of the cells and ribbons can be set as needed by those skilled in the art, such as arranging one ribbon between adjacent cells or one cell between adjacent ribbons. Corresponding to the cell loading unit and the ribbon loading unit, there can be one or two carrier moving units. For example, if there is one carrier moving unit, both the cell loading unit and the ribbon loading unit are correspondingly positioned thereto. As the substrate assembly passes through the cell loading station and the ribbon loading station successively via the carrier unit, the cells and ribbons are arranged in an array.

[0125] For example, there can be two carrier units, one for loading solar cells and the other for loading solder ribbon. The substrate assembly passes through the solar cell loading station and the other for loading solder ribbon sequentially via the two carrier units, completing the array arrangement of the solar cells and solder ribbon. Both carrier units can move in a stepping manner, or they can both move continuously at a predetermined speed, or one can move in a stepping manner while the other moves at a predetermined speed. Corresponding to the first direction, the solar cell loading unit can be positioned before the solder ribbon loading unit (passing through the solar cell loading station first, then entering the solder ribbon loading station), or the solder ribbon loading unit can also be positioned before the solar cell loading unit (passing through the solder ribbon loading station first, then entering the solar cell loading station).

[0126] In one embodiment, the carrier unit is capable of moving the substrate assembly in a step-by-step manner; the moving carrier unit can move the substrate assembly past the cell loading station and the solder ribbon loading station; the cell loading station is the station where the cell loading unit moves the cell onto the substrate assembly, and the solder ribbon loading station is the station where the solder ribbon loading unit moves the solder ribbon onto the substrate assembly. Specifically, the carrier unit can move the substrate assembly in a step-by-step manner, with each step moving one row of cell onto the substrate assembly and one row of solder ribbon onto the substrate assembly.

[0127] In another embodiment, the support unit includes a first movable support unit and a second movable support unit. The first movable support unit can drive the substrate assembly to move continuously at a predetermined speed or move in a stepping manner, and the second movable support unit can drive the substrate assembly to move in a stepping manner.

[0128] The first moving carrier unit can drive the substrate assembly through the solder ribbon loading station, which is a station where the solder ribbon loading unit feeds the solder ribbon to the substrate assembly at a predetermined speed.

[0129] The second moving carrier unit can drive the substrate assembly through the cell loading station, which is the station where the cell loading unit transports cells to the substrate assembly.

[0130] The first mobile support unit can be an air-bearing support plate, a linear motion mechanism, and a gripper mechanism. The second mobile support unit can be a linear motor or a rack and pinion structure, which is more suitable for continuous movement. If it is a stepping method, it can also be an air-bearing support plate, a linear motion mechanism, and a gripper mechanism. Of course, any other support unit structure that can achieve the desired purpose is acceptable.

[0131] Specifically, when the solar cells are loaded into the workstation, the arrangement of all solar cells is completed; when the substrate assembly passes through the solder ribbon loading station via the first moving support unit, the arrangement of all solder ribbons is completed. At this time, one moving support unit can be a step-type moving support unit, which is more suitable for solar cell arrangement; the other moving support unit can be a continuously moving support unit, which is more suitable for solder ribbon arrangement. This method is used to improve the arrangement efficiency and accuracy.

[0132] As an optional implementation, a mobile carrier unit is used, which moves in a step-by-step manner, and the cell loading unit and the ribbon loading unit are arranged sequentially along the first direction.

[0133] Furthermore, such as Figure 1The moving support unit includes an air-bearing support plate 9 and a conveying mechanism. The air-bearing support plate 9 supports the substrate assembly. The cell loading unit arranges the cells onto the substrate assembly supported by the air-bearing support plate 9, and the solder ribbon loading unit arranges the solder ribbon onto the substrate assembly supported by the air-bearing support plate 9. The conveying mechanism moves the substrate assembly on the air-bearing support plate 9 a predetermined distance per unit time (either by stepping or by continuously moving the predetermined distance at a predetermined speed). By supporting the substrate assembly with the air-bearing support plate 9 and moving the substrate assembly with the conveying mechanism, friction between the substrate assembly and existing support components is avoided, thus preventing the substrate assembly from affecting its quality.

[0134] Of course, the carrier unit can also be set as a conveyor belt or other moving unit that clamps and moves the substrate assembly, which will not be described in detail here.

[0135] Furthermore, the conveying mechanism includes a linear motion mechanism 8 and a gripper mechanism. There are two linear motion mechanisms 8, symmetrically arranged on both sides of the air-bearing support plate 9. The gripper mechanism includes two grippers symmetrically arranged on the two linear motion mechanisms 8. The two linear motion mechanisms 8 are used to drive the two grippers to move synchronously. Through the gripping of the two grippers, the corresponding substrate assembly can move a predetermined distance per unit time (moving in a stepping manner or continuously moving a predetermined distance at a predetermined speed). The linear motion mechanism 8 and the gripper mechanism have higher transmission accuracy, which is beneficial for more accurate arrangement of the battery cells and solder ribbons onto the substrate assembly.

[0136] Of course, conveyor belts or robotic arms can also be used as conveying mechanisms, which will not be elaborated on here and are all within the scope of protection.

[0137] Furthermore, there are multiple gripper mechanisms arranged along the extension direction of the air-bearing support plate 9. In two adjacent gripper mechanisms, the first region of the substrate assembly held by the gripper mechanism near the input end of the conveying mechanism completes the arrangement of battery cells and solder ribbons while being gripped, and the second region of the substrate assembly held by the gripper mechanism near the output end of the conveying mechanism completes the arrangement of battery cells and solder ribbons while being gripped. The first region and the second region are independent of each other. Through the above arrangement, the continuity of the overall processing is ensured.

[0138] In this embodiment, there are two gripper mechanisms. The first region and the second region together constitute the layout area of ​​the entire substrate assembly.

[0139] Specifically, the first and second gripper mechanisms form the first group, while the third and fourth gripper mechanisms form the second group. The first group of gripper mechanisms clamps and drives the substrate assembly in a stepping motion to arrange the battery cells and solder ribbons. After a portion of a module is arranged, the second group of gripper mechanisms clamps the module to arrange the remaining battery cells and solder ribbons. Simultaneously, the first group of gripper mechanisms releases the module and returns to pick up the next substrate assembly, closely following the previous group of substrate assemblies. The two sets of linear motors work together to enable continuous production and improve equipment capacity.

[0140] Furthermore, such as Figure 1 As shown in the embodiment of the present invention, the photovoltaic module arrangement device further includes an input transmission mechanism 6 and an output transmission mechanism 10. The input transmission mechanism 6 can transport the substrate assembly to the carrier unit, and the output transmission mechanism 10 can output the substrate assembly from the carrier unit.

[0141] Both the input transmission mechanism 6 and the output transmission mechanism 10 are transmission belt structures. Their movement enables the substrate assembly to move along the extension directions of the input transmission mechanism 6 and the output transmission mechanism 10.

[0142] The input transmission mechanism 6, the air flotation support plate 9, and the output transmission mechanism 10 extend in the same direction.

[0143] Preferably, the input transmission mechanism 6 is capable of vertical movement relative to the support unit, allowing it to be higher or lower than the support unit; similarly, the output transmission mechanism 10 is capable of vertical movement relative to the support unit, allowing it to be higher or lower than the support unit. Through the vertical movement of the input transmission mechanism 6 and the output transmission mechanism 10, the input and output of the support components on the support unit can be achieved. The extension direction of the linear motion mechanism is the same as the extension directions of the input transmission mechanism 6, the air-bearing support plate 9, and the output transmission mechanism 10. The air-bearing support plate 9 can have multiple rows and columns. To facilitate the transfer of substrate assemblies from the input transmission mechanism 6 to the air-bearing support plate 9, or to facilitate the output transmission mechanism 10 conveying the arranged substrate assemblies from the air-bearing support plate 9, the air-bearing support plate 9 can be staggered with the input transmission mechanism 6 and the output transmission mechanism 10, except for their vertical movement. During operation, the input transmission mechanism 6 docks with the previous station to transport the substrate assembly into the photovoltaic module arrangement device. Then, the input transmission mechanism 6 descends to place the incoming material, including the substrate assembly, onto the air-floating support plate 9. After positioning, the substrate assembly is driven to move along the first direction (lateral direction) by two linear movement mechanisms 8 and two sets of gripper mechanisms, advancing the length of one or two cells each time. After the cells (and solder strips) to be arranged are arranged, the output transmission mechanism 10 outputs the material to the next station.

[0144] Furthermore, the cell loading unit includes a cell feeding unit 2 and a cell transport unit 3. The cell feeding unit 2 is used to transport the cells; the cell transport unit 3 is connected to the output end of the cell feeding unit 2 and is used to transport the cells transported by the cell feeding unit 2 to the corresponding position of the substrate assembly.

[0145] In this embodiment, continuous loading of solar cells is achieved by setting up a solar cell loading unit 2 and a solar cell transport unit 3. Preferably, the solar cell transport unit 3 can be positioned to facilitate the arrangement of solar cells on the substrate assembly. Preferably, the solar cell transport unit 3 is mounted above the support unit.

[0146] Furthermore, such as Figure 3 As shown, the cell transport unit 3 includes a cell transport mechanism 27 for transporting multiple cells to corresponding positions on the substrate assembly. The cell transport mechanism 27 includes a cell transport drive device and multiple suction cup assemblies connected to the cell transport drive device, with the multiple suction cup assemblies arranged in a row at intervals. The carrier unit drives the substrate assembly along a first direction past the cell loading station. When the cell transport drive device drives the multiple suction cup assemblies to move from the cell loading station to above the substrate assembly, they are arranged in a direction perpendicular to the first direction. The cell loading station is the station where the cell loading unit moves the cells onto the substrate assembly. By arranging the cells onto the substrate assembly using multiple suction cups in a manner perpendicular to the substrate movement direction, the arrangement efficiency can be further improved.

[0147] The suction cup assembly is a conventional structure in the prior art. It can be in the form of a suction nozzle or a suction cup. The number of suction cups or suction nozzles is set according to the stability and size of the battery cell. Preferably, a single suction cup assembly includes two suction nozzles, which can simultaneously pick up both ends of the battery cell in the length direction.

[0148] Furthermore, to improve the accuracy of cell placement and soldering precision, the cell loading unit also includes a position adjustment device 28 for positioning multiple cells transported from the cell feeding unit 2. The cell transport mechanism 27 can transport the cells between the position adjustment device 28 and the corresponding position on the substrate assembly. After the cells are placed in the position adjustment device 28, their positions are adjusted, and then transported by the cell transport mechanism 27 until they are placed in the corresponding position on the substrate assembly. It should be noted that the position adjustment device 28 can be a position adjustment platform with a centering clamp positioning mechanism or an edge positioning mechanism on its side. Alternatively, the position adjustment device 28 can be itself an XYθ alignment platform (a three-axis precision alignment platform) used in conjunction with a CCD vision system. These position compensation structures are all conventional structures in the prior art, and their specific details will not be elaborated further.

[0149] Furthermore, the cell handling unit 3 also includes a cell support platform 22, which is mounted above the supporting unit and is used to carry multiple cells conveyed from the cell loading unit 2 at one time. The multiple cells are arranged in rows with intervals on the cell support platform 22. The cell handling mechanism 27 can at least transport the cells on the cell support platform 22 to the position adjustment device 28 for position compensation before transporting them to the corresponding position of the substrate assembly. The cell support platform 22 can be a conveyor belt.

[0150] Furthermore, the multiple suction cup assemblies are divided into at least two groups. All suction cup assemblies in each group are arranged in a straight line, with adjacent suction cup assemblies spaced apart. The cell handling drive device also drives one group of suction cup assemblies to move back and forth between the cell support platform 22 and the position adjustment device 28, while simultaneously driving the other group of suction cup assemblies to move back and forth between the position adjustment device 28 and the substrate assembly. By setting at least two groups of suction cup assemblies, a simultaneous pick-up and placement process can be achieved, further improving work efficiency.

[0151] Specifically, the cell loading unit 2 and the cell handling unit 3 include various forms:

[0152] As one of the forms, such as Figure 2 As shown, the cell loading unit 2 includes: a cell feeding mechanism; a cell conveying mechanism 24 connected to the cell feeding mechanism; a good cell inspection mechanism 19 (such as a CCD camera) for detecting defects in the cells; and a rotary conveying mechanism 20 for transferring defective cells detected by the good cell inspection mechanism 19 to the waste disposal area 25 or for rotating qualified cells to a specified direction and then transferring them to the cell carrier platform 22. The rotary conveying mechanism 20 can rotate the cells 180 degrees so that when the positive and negative electrodes of the cells need to be adjusted during loading, they can be rotated 180 degrees to accommodate this need. The cell conveying unit 3 transports the cells on the cell carrier platform 22 to the corresponding positions of the substrate assembly. The cell feeding mechanism includes: a first conveying mechanism 15A set at a certain angle to the conveying direction of the cell conveying mechanism 24 and a vacuum conveying mechanism 17 for transferring the cells on the first conveying mechanism 15A to the cell conveying mechanism 24. Furthermore, the cell feeding mechanism can also be a second conveying mechanism 15B with the same conveying direction as the cell conveying mechanism 24, and the output end of the second conveying mechanism 15B is connected to the input end of the cell conveying mechanism 24. Both the first conveying mechanism 15A and the second conveying mechanism 15B can be belt conveying mechanisms.

[0153] like Figure 2As shown, to accommodate the input of solar cells, the solar cell feeding unit 2 also includes a solar cell flipping mechanism 18, which is connected to the output end of the solar cell feeding mechanism. After flipping the solar cells, they enter the good product inspection mechanism 19 (such as a CCD camera, which takes pictures to detect whether they are good products).

[0154] Furthermore, in order to provide coarse compensation for the position of the battery cells, a battery cell position compensation position 21 is provided between the rotary conveying mechanism 20 and the battery cell placement plate 22.

[0155] The specific working process of the battery cell feeding unit 2 is as follows: If the battery cells flow in from the first conveying mechanism 15A, they are transported to the battery cell conveying mechanism 24 via the vacuum conveying mechanism 17. If the battery cells flow in from the second conveying mechanism 15B, they are directly connected to the battery cell conveying mechanism 24 and conveyed forward. Alternatively, they can be fed directly through the material box module and transported to the battery cell conveying mechanism 24 via the vacuum conveying mechanism 17. The battery cell conveying mechanism 24 transports the battery cells to the flipping mechanism 18, which flips the battery cells from face up to face down (the battery cells are defined as face up when feeding, and face down when arranging the battery cells). After the battery cells come out of the flipping mechanism 18, they are inspected for defects by the good product inspection mechanism 19. If there are damaged cells, they are transported to the waste position 25 by the rotary conveying mechanism 20. If they are good cells, they are rotated to the program-specified direction (the direction in which they can be directly arranged) by the rotary conveying mechanism 20. After the solar cells flow out of the station where the rotary conveying mechanism 20 is located, they flow into the solar cell position compensation position 21. The position of the solar cells is coarsely compensated by centering or side clamping, and then they enter the input end of the solar cell placement plate 22 in sequence.

[0156] like Figure 2 Figure 3 As shown, the battery cell handling unit 3 includes a battery cell support platform 22 and a battery cell handling mechanism 27. Specifically, the battery cell handling mechanism 27 includes an X-axis handling drive device 32, a battery cell handling linear motor assembly 33, a battery cell handling lifting cylinder 31 (i.e., the battery cell handling drive device), and a first suction cup assembly 29 and a second suction cup assembly 30 for picking up and releasing battery cells. Preferably, the position adjustment device 28 and the position of the battery cells output by the battery cell loading unit 2 are located above the support unit. The position adjustment devices 28 are multiple and arranged in rows to accommodate multiple rows of battery cells.

[0157] The position adjustment device 28 corresponds to the position of the solar cells output from the solar cell loading unit 2. Furthermore, a vision system corresponding to the position adjustment device 28 is included, located above the position adjustment device 28. The vision system is used to identify the position of the solar cells and calculate position compensation values. The solar cell transport mechanism 27 can transport the solar cells output from the solar cell loading unit 2 to the corresponding positions of the substrate assemblies transported by the position adjustment device 28 and the transport mechanism 1; and the solar cells from the position adjustment device 28 are transported to the corresponding positions of the substrate assemblies transported by the transport unit 1.

[0158] The vision system is preferably a CCD (Charge-coupled device) vision system, and the position adjustment device 28 is an XYθ alignment platform. The vision system is located directly above the position adjustment device 28. It takes pictures and calculates the position compensation value through the CCD vision system. The position adjustment device 28 compensates the position of the solar cell to the calibration position, and then the solar cell transport mechanism 27 transports the compensated solar cell to the substrate assembly.

[0159] In this system, the cell handling lifting cylinder 31 controls the descent of the first suction cup assembly 29, and the cell handling linear motor assembly 33 controls the descent of the second suction cup assembly 30. Driven by the X-axis handling drive device 32, the first suction cup assembly 29 and the second suction cup assembly 30 move along a first direction, respectively, to positions above the position adjustment device 28 and the cell arrangement station. The cell handling lifting cylinder 31 then controls the descent of the first suction cup assembly 29, and the cell handling linear motor assembly 33 controls the descent of the second suction cup assembly 30. It is understood that because the height of the substrate assembly is lower than the position adjustment device 28, the cell handling linear motor assembly 33 controls the second suction cup assembly 30 to descend above the cell arrangement station, achieving higher precision and smooth release of the cells, before it rises to a height higher than the position compensation device 28.

[0160] Preferably, the position adjustment device 28 has reserved space so that when switching between different battery cells, only the CCD calibration template needs to be switched, which can quickly switch between different specifications of products and has good compatibility.

[0161] To further improve work efficiency, this embodiment adopts a method of simultaneous picking and placing of battery cells. Specifically, the first suction cup assembly 29 is a suction cup assembly used to transport the battery cells output from the battery cell loading unit 2 (in this embodiment, it refers to the battery cells placed on the battery cell support platform 22) to the position adjustment device 28; the second suction cup assembly 30 is a suction cup assembly used to transport the battery cells from the position adjustment device 28 to the corresponding position of the substrate assembly transported by the conveying mechanism 1. During operation, the first suction cup assembly 29 and the second suction cup assembly 30 simultaneously pick up the battery cells that have been moved to the battery cell support platform 22 and the position adjustment device 28, respectively. Then, through the battery cell transport drive device, the first drive suction cup assembly 29 and the second suction cup assembly 30 move simultaneously, placing the multiple battery cells picked up by the two suction cup assemblies onto the position adjustment device 28 and the substrate assembly, respectively (i.e., the battery cells on the battery cell support platform 22 are transferred to the position adjustment device 28, and the battery cells on the position adjustment device 28 that have undergone position compensation are transferred to the substrate assembly), thereby achieving dual pick-up and dual placement of battery cells at corresponding positions on the battery cell support platform 22, the position adjustment device 28, and the substrate assembly. The battery cells compensated at one time are at least one row, preferably more than or equal to two rows. The first suction cup assembly 29 has at least one row of suction cups, preferably more than or equal to two rows, and the number of suction cups in each row is the same as the number of battery cells equidistantly arranged on the battery cell support platform 22. Similarly, the number of rows and quantities of suction cups on the second suction cup assembly 30 are the same as those on the first suction cup assembly 29.

[0162] like Figure 7 , Figure 8 As shown, another form differs from the above in that the cell loading units are no longer fed from one side of the carrier unit, but are instead positioned on both sides of the carrier unit. The advantages of this arrangement are its simple structure, small footprint, and ease of operation.

[0163] Specifically, such as Figure 7 , Figure 8 As shown, it includes a conveying mechanism 1 and a cell loading unit 2. The conveying mechanism 1 has the same structure as the previous type. The cell loading unit 2 includes a cell box 15 for placing and storing cells. The cell handling mechanism includes a cell handling mechanism 16 for transferring cells in the cell box 15 to the substrate assembly and the cell alignment platform 17.

[0164] The cell material box 15 can be divided into three parts: A inlet / outlet station, B inlet / outlet station, and pick-up station. The material box filled with cells enters from either A inlet / outlet station or B inlet / outlet station, and is then moved to the pick-up station 19 by a cylinder. The cells are then removed by the cell transport mechanism 16.

[0165] The cell alignment platform 17 is used to position the cells that are transported from the cell feeding box 15. The alignment method is mechanical positioning powered by a cylinder, such as centering clamp positioning or side-pushing positioning. The cell alignment platform 17 is located below the cell transport mechanism 16.

[0166] The cell handling mechanism 16 includes multiple suction cup assemblies and a drive device for moving these assemblies. The suction cup assemblies of the cell handling mechanism 16 can also be divided into at least two groups, each group including multiple suction cup assemblies arranged in rows. The simultaneous operation of both groups of suction cup assemblies enables dual pick-up and placement of cells. Alternatively, an XYθ compensation platform can be used in conjunction with a CCD vision system.

[0167] like Figure 9 As shown, the third type of cell loading unit differs from the second type in that the cell loading method is changed from external basket loading to internal loading. The cell loading unit 2 includes a cell conveying structure 61 arranged along the transmission direction of the carrying unit, a basket that moves along the cell conveying structure 61, and a cell picking mechanism 62. The cell conveying structure 61 has cell picking positions.

[0168] Furthermore, the cell loading unit also includes a secondary positioning platform 63 (i.e., the position adjustment device mentioned above) and a cell transport mechanism 64. The cell picking module 62 removes the cells and places them on the secondary positioning platform 63 for secondary positioning (this can be mechanical positioning or a method using an XYθ compensation platform in conjunction with a CCD vision system). After positioning, the cell transport mechanism 64 (which includes a rotary motor that can rotate the suction cup assembly by a certain angle, such as 90 degrees) transports the cells onto the substrate assembly. In this embodiment, because the material movement direction of the cell loading unit and the solder ribbon loading unit is parallel to the extension direction of the carrying unit, the floor space can be reduced. Additional rotation is required for the transport of the cells and solder ribbon.

[0169] In this embodiment, the solder ribbon loading unit includes: a solder ribbon feeding mechanism; a solder ribbon cutting mechanism for cutting the solder ribbon into multiple segments, the input end of which is connected to the output end of the solder ribbon feeding mechanism; and a solder ribbon transfer mechanism for moving the cut solder ribbon segments to corresponding positions on the substrate assembly. Alternatively, the cut solder ribbon can be directly transferred to the solder ribbon loading unit for loading. This solder ribbon cutting system can achieve the cutting of multiple solder ribbon segments, and by synchronously moving these segments through the solder ribbon feeding unit, it can effectively improve production efficiency and facilitate subsequent operations, thus enhancing overall production efficiency.

[0170] Furthermore, to further improve production efficiency, the welding strip cutting mechanism includes multiple welding strip cutting units connected in sequence. These multiple welding strip cutting units are arranged in a straight line.

[0171] Furthermore, the ribbon transfer mechanism 41 includes a ribbon transfer drive device and multiple suction cup assemblies connected to the ribbon transfer drive device, with the multiple suction cup assemblies arranged in a row at intervals. The carrying unit drives the substrate assembly to pass through the ribbon loading station along the first direction, and the ribbon transfer drive device drives the multiple suction cup assemblies to move from the ribbon loading station to above the substrate assembly and arrange them in a direction perpendicular to the first direction. The ribbon loading station is the station where the ribbon loading unit moves the ribbon onto the substrate assembly. By arranging the solar cells onto the substrate assembly using multiple suction cups in a manner perpendicular to the substrate movement direction, the solar cell arrangement efficiency can be further improved.

[0172] Furthermore, the ribbon feeding mechanism 38 includes multiple ribbon loading rolls arranged in rows at intervals, with the ribbon loading rolls positioned above the carrying unit. The carrying unit drives the substrate assembly along a first direction past the ribbon loading rolls, and the multiple ribbon loading rolls are arranged in a direction perpendicular to the first direction. This method is suitable for situations where the ribbon to be fixed on the battery cell is in a complex position, where adhesive is applied in advance before the battery cell is fed in, or where the battery cell or ribbon is melted. By arranging multiple ribbon loading rolls onto the substrate assembly in a manner perpendicular to the substrate movement direction, the ribbon arrangement efficiency can be further improved.

[0173] Furthermore, to control the distance between the multiple weld strip segments after cutting and improve the accuracy of the weld strip placement when feeding the weld strip to the required position, the weld strip cutting system also includes a spacing limiting mechanism for limiting the distance between the multiple weld strip cutting units. The spacing limiting mechanism includes a spacing linear drive device and multiple spacing limiting components connected one-to-one with the weld strip cutting units. The spacing linear drive device drives the multiple spacing limiting components to adjust the distance between adjacent cutting units along the arrangement direction of the multiple weld strip cutting units. The spacing limiting mechanism allows the multiple weld strip cutting units to be separated from each other and also achieves equidistant separation between adjacent cutting units. This ensures that the distance between two adjacent weld strip segments arranged in a straight line after cutting is controlled within the required range, improving the accuracy when multiple weld strip segments are simultaneously transported to the required position.

[0174] The spacing limiting assembly includes a spacing limiting connector and a spacing limiting member disposed on the welding strip cutting unit. In two adjacent spacing limiting assemblies, the spacing limiting connector of one spacing limiting assembly is connected to the spacing limiting member of the other spacing limiting assembly. The spacing limiting connector has a first limiting surface and a second limiting surface, which are respectively driven by a spacing linear drive mechanism to achieve limiting contact between the first and second limiting surfaces and the spacing limiting member. Specifically, the spacing limiting member has a bayonet structure. The spacing limiting connector includes a first connecting shaft segment, a second connecting shaft segment, and a third connecting shaft segment connected in sequence. The diameter of the second connecting shaft segment is smaller than the diameters of the first and third connecting shaft segments. The opening size of the bayonet structure is smaller than the diameters of the first and third connecting shaft segments but larger than the diameter of the second connecting shaft segment.

[0175] Specifically, the solder strip loading unit includes various forms, such as... Figure 6 As shown.

[0176] As one of the forms, such as Figure 5 As shown, the welding strip feeding unit includes a feeding machine platform 38, a feeding shaft 39, a tensioning wheel group 40, a welding strip transfer mechanism 41, a welding strip pulling mechanism 42, a spacing limiting mechanism, a welding strip end cutting mechanism 45, and a welding strip fixing mechanism 46.

[0177] Specifically, the system includes a strip pulling mechanism 42 for clamping the strip output from the feed roll 39 mounted on the strip feeder 38, the strip pulling mechanism 42 being movable in directions approaching and away from the strip feeder 38; a strip fixing mechanism 46 for clamping the strip, the strip fixing mechanism 46 being located on the movement trajectory of the strip pulling mechanism 42; and a strip cutting unit located on the side of the strip fixing mechanism 46 away from the strip feeder 38 and on the movement trajectory of the strip pulling mechanism 42. The number of strip cutting units is multiple, including a strip end cutting mechanism 45 and at least one partial strip cutting unit 44.

[0178] To improve production efficiency, the welding strip cutting unit includes multiple welding strip fixing positions and a cutter for cutting the welding strip in the multiple welding strip fixing positions together.

[0179] The solder ribbon transfer mechanism 41 includes a dual-drive linear slide module 48 and a vertical motion module 49 that moves along the driving direction of the dual-drive linear slide module 48. The vertical motion module 49 has multiple solder ribbon pick-and-place devices, each corresponding to a solder ribbon cutting unit. This configuration enables the linear movement and lifting of multiple solder ribbon segments, facilitating the simultaneous transfer of multiple solder ribbons arranged in rows to the corresponding positions on the substrate assembly. Alternatively, the solder ribbon transfer mechanism 41 can be any other functional structure, such as a robotic arm, which includes multiple suction cup modules to achieve synchronous transfer of multiple solder ribbons.

[0180] The welding strip loading unit 5 also includes a flux box 47 located at the output end of the welding strip feeder 38; the welding strip output by the welding strip feeder 38 is immersed in the flux box 47 and then enters the welding strip cutting mechanism.

[0181] The welding strip is initially fed from the feeding shafts 39 (four sets in total) in the feeding machine 38, tensioned by the tensioning wheel set 40, and then soaked in flux in the flux box 47 to improve the welding effect in subsequent stages. Next, the welding strip pulling mechanism 42, driven by its linear drive module, grips the welding strip with its claws. At this time, the lifting cylinder of the welding strip fixing mechanism 46 rises, allowing the welding strip pulling mechanism 42 to smoothly pull out multiple (e.g., 6 strips, the number of strips depends on the component panel) lengths of welding strip. Then, the welding strip is fixed. The lifting cylinder of mechanism 46 descends, and the grippers of the welding strip pulling mechanism 42 release and reset; the welding strip positioning mechanism (such as a vacuum adsorption device) of the partial welding strip cutting mechanism 44 is activated to ensure that the position of the welding strip does not shift, and then the welding strip end cutting mechanism 45 and the partial welding strip cutting mechanism 44 operate simultaneously to cut the welding strip into multiple segments; then, the spacing linear drive mechanism 43 of the spacing limiting mechanism is activated and the multiple groups of welding strips are separated at equal intervals, and then the entire group of welding strips is transported and placed in the corresponding position of the substrate assembly by the welding strip transfer mechanism 41.

[0182] As another form, this one differs from the previous one in that the solder ribbon loading units no longer feed from one side of the substrate assembly, but are instead positioned on both sides of the carrying unit. Furthermore, the solder ribbon feeding mechanism is placed parallel to the direction of movement of the substrate assembly. The advantages of this method are its simple structure, small footprint, and ease of operation. In addition, the solder ribbon transfer mechanism is replaced by a robotic arm.

[0183] like Figure 7 As shown, the ribbon transfer mechanism includes a four-axis manipulator and a row of suction cup assemblies. In this embodiment, there are two sets of ribbon transfer mechanisms, located on both sides of the support unit. The ribbon transfer mechanism transports the ribbon from the ribbon cutting mechanism to the corresponding positions on the support unit using multiple suction cup assemblies.

[0184] Furthermore, the photovoltaic module arrangement device provided in this embodiment of the invention also includes a solder ribbon dispensing unit 4, which is used to adhere solder ribbons to the solar cells. The solder ribbon dispensing unit 4 allows adhesive to be applied to the corresponding positions on the solar cells before or after loading. When arranging the solder ribbons, this ensures the ribbons adhere to the solar cells, preventing movement of the solder ribbons during subsequent photovoltaic module movement, thus guaranteeing the positioning and effectiveness of the arrangement and welding.

[0185] In one non-limiting implementation, the solder ribbon dispensing unit 4 is located at the input end of the cell loading unit. After the cell is dispensed by the solder ribbon dispensing unit 4, it enters the cell loading unit.

[0186] Among them, the welding strip dispensing unit 4 includes a screen printing component, which prints adhesive onto the corresponding position of the battery cell using the screen printing method. The screen printing method can make the amount of adhesive applied to each position uniform, and the printing and dispensing speed is fast and the precision is high, making it particularly suitable for some application scenarios with complex adhesive application.

[0187] In another embodiment, the solder ribbon dispensing unit 4 is disposed between the cell loading unit and the solder ribbon loading unit. The solder ribbon dispensing unit 4 performs a dispensing operation on the cell that has been moved to the corresponding position on the substrate assembly. That is, after dispensing the solder ribbon on the cell, the solder ribbon is moved to the corresponding position on the substrate assembly to complete the fixation of the solder ribbon and the cell.

[0188] like Figure 4 As shown, the solder ribbon dispensing unit 4 includes a dispensing valve 34 and a dispensing drive mechanism connected to the dispensing valve 34 and driving the dispensing valve 34 to move.

[0189] The dispensing valve 34 is preferably a non-contact piezoelectric dispensing valve.

[0190] The dispensing drive mechanism includes a dispensing linear drive device 35, a lateral movement cylinder 36, and a lifting cylinder 37. The movement directions of the dispensing linear drive device 35, the lateral movement cylinder 36, and the lifting cylinder 37 are perpendicular to each other, realizing corresponding movement along the X, Y, and Z axes, which allows the dispensing valve to be accurately aligned with the dispensing position.

[0191] A linear dispensing drive 35 drives multiple dispensing valves 34 and a lateral movement cylinder 36 in a linear motion, uniformly dispensing adhesive onto the solder strip placement positions of the battery cells at a constant speed. The lifting cylinder 37 rises when the dispensing valves 34 require maintenance or repair, and lowers when the valves 34 are in operation. The lateral movement cylinder 36 is normally in the extended position; its retraction is used to adjust the position of the dispensing valves 34, enabling dispensing of adhesive onto battery cells with different spacing.

[0192] This invention also provides a photovoltaic module production system, including a welding machine and a photovoltaic module arrangement device as described above. The welding machine is located at the output end of the photovoltaic module arrangement device, and the module structure arranged by the photovoltaic module arrangement device is welded by the welding machine.

[0193] In this embodiment, the welding machine includes: a pressure plate assembly and a support plate assembly arranged vertically at intervals, wherein the support plate assembly is located below the pressure plate assembly; a drive module corresponding to the pressure plate assembly and the support plate assembly, used to enable the pressure plate assembly and the support plate assembly to move closer to each other or further away from each other under the drive of the drive module; multiple laser scanning heads arranged above the pressure plate assembly or below the support plate assembly; and a translation module connected to the multiple laser scanning heads, used to drive the laser scanning heads to move so as to complete the laser welding operation on the entire surface of the material to be welded.

[0194] Furthermore, the photovoltaic module production system also includes: a lower flexible material feeding unit located at the input end of the photovoltaic module arrangement device and used for conveying the lower flexible material; a lower rigid material feeding unit located at the input end of the lower flexible material feeding unit and used for conveying the lower rigid material; an upper flexible material feeding unit located at the output end of the welding machine and used for conveying the upper flexible material to the welded photovoltaic modules; an upper rigid material feeding unit located at the output end of the upper flexible material feeding unit and used for conveying the upper rigid material to the welded photovoltaic modules; and a laminator for laminating the total photovoltaic module, wherein the total photovoltaic module is the module after arranging the upper flexible material and the upper rigid material. Through the above configuration, the overall production of photovoltaic modules is realized.

[0195] Of course, additional units or laminators can be installed as described above, which will not be specifically described here and are all within the scope of protection.

[0196] Preferably, the upper rigid plate can be a glass substrate, and the upper flexible layer is an EVA (ethylene-vinylacetate copolymer) or POE component.

[0197] The photovoltaic module production system also includes a layout detection buffer device located between the photovoltaic module layout device and the welding machine. This device inspects the layout of the modules after they have passed through the layout device, ensuring they are within acceptable limits before proceeding to the welding machine for welding.

[0198] The photovoltaic module production system also includes inspection equipment located between the welding machine and the upper flexible material feeding unit. The inspection equipment includes at least one of visual inspection, EL (electroluminescence) inspection equipment, and PL (photoluminescence) inspection equipment. The visual inspection can be carried out using a CCD camera and / or a microcrack detection device. The inspection equipment is used to inspect the welding quality.

[0199] The photovoltaic module production system provided in this embodiment of the invention further includes a busbar discharge device; the busbar discharge device is located between the lower flexible layer feeding unit and the photovoltaic module arrangement device; or, the busbar discharge device and the photovoltaic module arrangement device are located at the same workstation. A busbar is a conductive connecting component that connects solar cells into battery strings via solder strips, and enables connections between different battery strings.

[0201] The carrier unit carries the substrate assembly, which includes a lower rigid plate and a lower flexible layer.

[0202] Multiple solar cells and multiple solder ribbons are arranged on a substrate assembly. As the substrate assembly moves, the multiple solar cells are laid in rows and spaced apart on the substrate assembly to form a solar cell array, and the multiple solder ribbons are laid in rows and spaced apart on the substrate assembly to form a solder ribbon array.

[0203] With the above setup, in addition to improving the yield of the module production line and achieving production continuity, the arrayed battery cells and solder ribbons can effectively improve the arrangement efficiency and further improve production efficiency.

[0204] In this embodiment, the multiple solar cells are arranged in rows with spacing, with one or more rows of solar cells, and adjacent solar cells in each row spaced apart. Adjacent rows of solar cells are also spaced apart. Similarly, the multiple solder ribbons are arranged in rows with spacing, with adjacent solder ribbons in each row spaced apart. Adjacent rows of solder ribbons are also spaced apart. Of course, the placement of the solder ribbons depends on the arrangement of the solar cells on the substrate assembly.

[0205] In this embodiment, the photovoltaic module arrangement device further includes a solder ribbon dispensing unit 4, which is used to attach solder ribbons to the solar cells.

[0208] The carrier unit can simply move the substrate assembly. In one embodiment, specifically in the step of arranging multiple battery cells and multiple solder ribbons on the substrate assembly, the carrier unit moves the substrate assembly along a first direction a predetermined distance per unit time (moving in steps or continuously moving a predetermined distance at a predetermined speed).

This method improves arrangement efficiency and accuracy. Alternatively, the carrier unit can move the substrate assembly in other ways.

The first moving support unit drives the substrate assembly to move continuously at a predetermined speed or to move in a step manner, and the second moving support unit drives the substrate assembly to move in a step manner; wherein, the two moving support units can be located at two different work stations and move separately.

[0210] The first moving carrier unit drives the substrate assembly to pass through the solder ribbon loading station corresponding to the solder ribbon loading unit along the first direction. At the solder ribbon loading station, multiple solder ribbons are arranged on the substrate assembly along a second direction perpendicular to the first direction.

[0211] The second moving support unit drives the substrate assembly along the first direction through the battery cell loading station corresponding to the battery cell loading unit. At the battery cell loading station, multiple battery cells are arranged on the substrate assembly along a second direction perpendicular to the first direction. This method improves the arrangement efficiency and accuracy.

[0216] Since the above-mentioned photovoltaic module arrangement method has the above-mentioned technical effects, the photovoltaic module production method with the above-mentioned photovoltaic module arrangement method should also have the same technical effects, and will not be described in detail here.

[0217] Furthermore, after the step of welding the solder strips and cells in the arranged components, the process also includes: conveying upper flexible material and upper rigid material to the welded photovoltaic module; and laminating the photovoltaic module, which is a module with upper flexible material and upper rigid material arranged in the photovoltaic module.

[0218] In this embodiment, before the step of welding the solder ribbons and battery cells in the arranged components, an arrangement detection is also included.

This inspection can be performed using inspection equipment, including at least one of visual inspection, EL (electroluminescence) inspection equipment, and PL (photoluminescence) inspection equipment.

That is, the cell is first fed onto the substrate assembly, then the dispensing operation is performed on the cell, and finally the solder ribbon is fed to fix the solder ribbon to the cell.

[0223] During work:

As the substrate assembly moves, the multiple solar cells are laid in rows and spaced apart on the substrate assembly to form a solar cell array, and the multiple solder ribbons are laid in rows and spaced apart on the substrate assembly to form a solder ribbon array. In the step of arranging the multiple solar cells and multiple solder ribbons on the substrate assembly: first, the solar cells are arranged on the substrate assembly, then adhesive is applied to the solar cells, and finally, the solder ribbons are fixed to the solar cells by adhesive application.
