[0035] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0036] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0039] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0040] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0041] In the manufacturing process of solar cells, the cells need to be transferred through baskets to complete processes such as transfer, cleaning, and inspection. However, when the cells are inserted into the baskets, the orientation of the baskets is not the same as the orientation required for subsequent processes, necessitating the baskets to be flipped. Traditionally, this is done manually, which is time-consuming, labor-intensive, and inefficient.

[0042] Please see Figure 1 To alleviate the above problems, the applicant, after in-depth research, designed a flipping device 100. The flipping device 100 includes a frame 10, a feeding component 20, a flipping component 30, a first transport component 40, and a second transport component 50. The feeding component 20 and the first transport component 40 are arranged sequentially along the first horizontal direction X. The flipping component 30 is rotatably mounted on the frame 10. The flipping component 30 includes an annular frame 31 with a hollow area 311. The first transport component 40 and the second transport component 50 are both located in the hollow area 311 and are arranged sequentially along the vertical direction Z. The annular frame 31 is used to drive the first transport component 40 and the second transport component 50 to rotate 180°. One of the first transport component 40 and the second transport component 50 is used to receive the part to be flipped from the feeding component 20 before flipping. The other of the first transport component 40 and the second transport component 50 is used to receive the part to be flipped from the first transport component 20 after flipping and to transport the part to be flipped outward.

[0043] by Figure 1 For example, the first horizontal direction X is the direction from front to back.

[0044] As an example, the part to be flipped can be a flower basket, a battery cell, or other components, which can be selected according to actual production needs.

[0045] The frame 10 mainly serves as a support and installation component. The frame 10 can be made of sheet metal, plastic, or other materials with better mechanical properties.

[0046] As an example, the feeding component 20 uses an automated guided vehicle (AGV) to achieve automatic feeding, thereby improving the production efficiency of the flipping device 100.

[0047] As an example, the first transport component 40 and the second transport component 50 have identical structures, and their relative positions adjust according to the rotation angle. Generally, initially, the first transport component 40 is located below the second transport component 50 and can receive the parts to be flipped from the feeding component 20. After flipping 180°, the second transport component 50 is located below the first transport component 40 and can receive the parts to be flipped from the first transport component 40, subsequently conveying them outwards. After this, the positions and functions of the first transport component 40 and the second transport component 50 are interchanged, and they cooperate to perform the next round of flipping of the parts to be flipped.

[0048] In actual operation, after the loading component 20 completes loading via the automatic guide vehicle, it conveys the part to be flipped to the first transport component 40. The first transport component 40 receives the part to be flipped from the loading component 20. Then, the annular frame 31 drives the first transport component 40, the second transport component 50, and the part to be flipped to rotate 180° to achieve a 180° flip of the part to be flipped. Finally, the second transport component 50 receives the part to be flipped from the first transport component 40 and conveys it outward so that the part to be flipped can proceed to the next process.

[0049] Therefore, in this application, by cooperating with the feeding component 20, the flipping component 30, the first transport component 40, and the second transport component 50, the workpiece to be flipped can be automatically flipped 180°. This flipping method saves time and labor, effectively improving production efficiency. In addition, the method of using the flipping component 30, the first transport component 40, and the second transport component 50 to achieve the flipping of the workpiece has a simple structure, occupies a small area, and can also reduce the manufacturing cost of the flipping device 100.

[0050] Please continue reading. Figure 1 In some embodiments, there are multiple feeding components 20, first transport components 40, and second transport components 50, all arranged at intervals along a second horizontal direction Y perpendicular to the first horizontal direction X. Each feeding component 20 corresponds one-to-one with a first transport component 40 or a second transport component 50. One of the first transport components 40 and the second transport component 50 receives the component to be flipped from the corresponding feeding component 20, while the other receives the component to be flipped from the first transport component 40 or the second transport component 50. Thus, in the second horizontal direction Y, multiple feeding components 20 can achieve multi-station feeding, and multiple first transport components and multiple second transport components working together can achieve multi-station flipping. This allows for the simultaneous flipping of multiple components, resulting in high flipping efficiency and good versatility.

[0051] As an example, with Figure 1For example, the second horizontal direction Y is the left and right direction. There are two of each of the feeding component 20, the first transport component 40 and the second transport component 50. The flipping device 100 can realize dual-station feeding and dual-station flipping.

[0052] It is worth mentioning that in this embodiment, the automated guided vehicle sequentially feeds materials to each feeding component 20. After all feeding components 20 have finished feeding, all feeding components 20 operate synchronously and transport the parts to be flipped to their respective first transport components 40. Then, all the corresponding first transport components 40 and second transport components 50 cooperate to flip the parts to be flipped. After that, all the second transport components 50 receive the corresponding parts to be flipped and transport the corresponding parts to be flipped outward.

[0053] Please see Figure 2 In some embodiments, the feeding assembly 20 includes a feeding motor 21, a first feeding drive wheel, a second feeding drive wheel 22, a feeding drive shaft 23, a feeding conveyor belt 24, multiple feeding drive wheels 25, multiple feeding driven wheels 26, and multiple feeding conveyor belts 27. The first feeding drive wheel is fixed to the output shaft of the feeding motor 21. The second feeding drive wheel 22 and all the feeding drive wheels 25 are fixed to the feeding drive shaft 23. The feeding conveyor belt 24 is sleeved on the first feeding drive wheel and the second feeding drive wheel 22. The feeding drive wheels 25 and the feeding driven wheels 26 correspond one-to-one with the feeding conveyor belts 27. The feeding conveyor belts 27 are sleeved on the corresponding feeding drive wheels 25 and feeding driven wheels 26. All the feeding conveyor belts 27, all the feeding drive wheels 25, and all the feeding driven wheels 26 are arranged at intervals along the second horizontal direction Y.

[0054] As an example, the feeding motor 21 can be a servo motor, a motor, or other drive structure, which can be set according to the requirements.

[0055] As an example, both the feeding conveyor belt 24 and the feeding conveyor belt 27 can be belts, chains or other conveying structures, and there is no specific limitation here.

[0056] In actual operation, in the feeding assembly 20, the feeding motor 21 works, and its power is transmitted sequentially through the first feeding drive wheel, the feeding conveyor belt 24, the second feeding drive wheel 22, the feeding drive shaft 23, and all the first feeding drive wheels 25 to all the feeding conveyor belts 27, so as to drive all the feeding conveyor belts 27 to run, thereby enabling all the feeding conveyor belts 27 to receive the parts to be flipped and drive the parts to be flipped to move, thus completing the feeding of the first transport assembly 40.

[0057] In this application, all the feeding conveyor belts 27 in the feeding assembly 20 cooperate to jointly carry and transport the same piece to be flipped, thereby improving the stability of the conveying of the piece to be flipped. The feeding motor 21 transmits power synchronously to all the feeding conveyor belts 27 in the same group through the first feeding drive wheel, the second feeding drive wheel 22, the feeding conveyor belt 24 and the feeding drive shaft 23. All the feeding conveyor belts 27 in the same group can be driven by one feeding motor 21, which simplifies the structure of the flipping device 100 and thereby reduces the manufacturing cost of the flipping device 100.

[0058] Of course, the structure of the feeding assembly 20 is not limited to the one described above. For example, the feeding assembly 20 may only include a feeding motor 21, multiple feeding drive wheels 25, multiple feeding driven wheels 26 and multiple feeding conveyor belts 27. All the feeding drive wheels 25 in the feeding assembly 20 are arranged at intervals on the output shaft of the feeding motor 21.

[0059] In the above embodiments, each group of feeding components 20 has an independently configured feeding motor 21. In other embodiments, all groups of feeding components 20 may share the same feeding motor 21. For example, all feeding drive wheels 25 in all feeding components 20 may be spaced apart on the output shaft of the feeding motor 21. Please refer to [link / reference]. Figure 2 In some embodiments, a first blocking cylinder 28 is provided between at least two adjacent feeding conveyor belts 27 in the feeding assembly 20. The telescopic shaft of the first blocking cylinder 28 is used to block the parts to be flipped on the feeding conveyor belt 27 from retreating to the outside of the feeding conveyor belt 27 in a direction opposite to the first horizontal direction X.

[0060] Preferably, a first blocking cylinder 28 is provided between each pair of adjacent feeding conveyor belts 27 in the feeding assembly 20.

[0061] In actual operation, the automated guided vehicle (AGV) moves fully loaded with the parts to be flipped to the loading assembly 20 and docks with the loading conveyor belt 27 of the loading assembly 20 for loading. The number of parts to be flipped on each loading assembly 20 can be set according to actual needs. Taking five parts to be flipped as an example, when the loading assembly 20 has five parts to be flipped, and the five parts to be flipped pass the first blocking cylinder 28 under the operation of the loading conveyor belt 27, the telescopic shaft of the first blocking cylinder 28 extends and protrudes upward from the loading conveyor belt 27 in the same group of loading assemblies 20, so as to prevent all the parts to be flipped on the loading conveyor belt 27 from retreating in the opposite direction to the first horizontal direction X, thereby ensuring that the parts to be flipped on the loading conveyor belt 27 can be transported to the first transmission assembly.

[0062] It is worth noting that during the process of the automated guided vehicle feeding the material onto the feeding conveyor belt 27, the telescopic shaft of the first blocking cylinder 28 needs to be retracted to below the feeding conveyor belt 27 of the same feeding assembly 20, so as to avoid affecting the feeding of the automated guided vehicle onto the feeding assembly 20.

[0063] Please see Figure 1 and Figure 2 Furthermore, in some embodiments, a second blocking cylinder 29 is provided between at least two adjacent feeding conveyor belts 27 in the feeding assembly 20. The second blocking cylinder 29 is located close to the flipping assembly 30 relative to the first blocking cylinder 28. The telescopic shaft of the second blocking cylinder 29 is used to block the remaining items to be flipped from being transported to the first transport assembly 40 after the feeding conveyor belt 27 has transported one item to be flipped to the first transport assembly 40.

[0064] Preferably, a second blocking cylinder 29 is also provided between every two adjacent feeding conveyor belts 27 in the feeding assembly 20.

[0065] Specifically, the first blocking cylinder 28 and the second blocking cylinder 29, located between the two identical feeding conveyor belts 27, are arranged at intervals along the first horizontal direction X.

[0066] After the automated guided vehicle completes loading the material onto the loading assembly 20, the loading assembly 20 conveys the parts to be flipped to the corresponding first transport assembly. During this process, the telescopic shaft of the second blocking cylinder 29 retracts below the loading conveyor belt 27 to avoid affecting the conveyor belt 27's transport of the parts to be flipped. Each time the loading conveyor belt 27 loads a part to be flipped onto the first transport assembly 40, the telescopic shaft of the second blocking cylinder 29 extends and protrudes upwards from the loading conveyor belt 27 within the same loading assembly 20, preventing any remaining parts to be flipped on the loading conveyor belt 27 from moving along the first horizontal direction X onto the first transport assembly 40. This ensures that the cooperating first transport assembly 40 and second transport assembly 50 only operate to flip one part at a time. It is worth noting that during the loading process of the automated guided vehicle onto the feeding conveyor belt 27, the telescopic shaft of the second blocking cylinder 29 also needs to extend and protrude upwards from the feeding conveyor belt 27 within the same group of feeding components 20, in order to prevent the parts to be flipped from moving along the first horizontal direction X and falling off the feeding conveyor belt 27 during the loading process of the automated guided vehicle.

[0067] Please see Figure 3In some embodiments, the first transport assembly 40 includes a first motor 41, a plurality of first driving wheels 45, a plurality of first driven wheels 46, and a plurality of first conveyor belts 47. The first motor 41 is driven by all the first driving wheels 45. Each of the first driving wheels 45 and the first driven wheels 46 corresponds to a first conveyor belt 47, and the first conveyor belt 47 is fitted onto the corresponding first driving wheel 45 and the first driven wheel 46. The second transport assembly 50 includes a second motor 51, a plurality of second driving wheels 56, a plurality of second driven wheels 57, and a plurality of second conveyor belts 58. The second motor 51 is driven by all the second driving wheels 56. Each of the second driving wheels 56 and the second driven wheels 57 corresponds to a second conveyor belt 58, and the second conveyor belt 58 is fitted onto the corresponding second driving wheel 56 and the second driven wheel 57. All the first conveyor belts 47 and all the second conveyor belts 58 are arranged at intervals along a second horizontal direction Y.

[0068] As an example, the first motor 41 and the second motor 51 can be servo motors, motors, or other drive structures, which can be set according to requirements. As an example, the first transport assembly 40 also includes a first transmission wheel, a second transmission wheel 42, a first transmission shaft 43, and a first conveyor belt 44. The first transmission wheel is fixed on the output shaft of the first motor 41, the second transmission wheel 42 and all the first drive wheels 45 are fixed on the first transmission shaft 43, and the first conveyor belt 44 is sleeved on the first transmission wheel and the second transmission wheel 42, so that the power of the first motor 41 can be transmitted sequentially through the first transmission wheel, the first conveyor belt 44, the second transmission wheel 42, the first transmission shaft 43, and all the first drive wheels 45 to all the first conveyor belts 47, so as to drive the parts to be flipped on all the first conveyor belts 47 in the first transport assembly 40 to translate, thereby completing the purpose of the first transport assembly 40 to receive the parts to be flipped conveyed by the loading assembly 20. This design allows for flexible adjustment of the spacing between each pair of adjacent first drive wheels 45 in the first transport assembly 40, as well as the spacing between each pair of adjacent first conveyor belts 47, thereby enabling stable support of the parts to be flipped.

[0069] Of course, the structure of the first transport component 40 is not limited to the one described above. In other embodiments, all the first drive wheels 45 in the first transport component 40 may also be spaced apart on the output shaft of the first motor 41.

[0070] In the above embodiments, each group of first transport components 40 has an independently configured first motor 41. In other embodiments, all groups of first transport components 40 may share the same first motor 41. For example, all first drive wheels 45 in all first transport components 40 may be spaced apart on the output shaft of the first motor 41. As an example, the second transport component 50 also includes a third transmission wheel 52, a fourth transmission wheel 53, a second transmission shaft, and a second conveyor belt 55. The third transmission wheel 52 is fixed on the output shaft of the second motor 51, the fourth transmission wheel 53 and all second drive wheels 56 are fixed on the second transmission shaft, and the second conveyor belt 55 is sleeved on the third transmission wheel 52 and the fourth transmission wheel 53, so that the power of the second motor 51 can be transmitted sequentially through the third transmission wheel 52, the second conveyor belt 55, the fourth transmission wheel 53, the second transmission shaft, and all second drive wheels 56 to all second conveyor belts 58, thereby driving the parts to be flipped on all second conveyor belts 58 in the second transport component 50 to translate, thus completing the purpose of the second transport component 50 to transport the parts to be flipped outward. This design allows for flexible adjustment of the spacing between each pair of adjacent second drive wheels 56 in the second transport assembly 50, as well as the spacing between each pair of adjacent second conveyor belts 58, thereby enabling stable outward transport of the parts to be flipped.

[0071] Of course, the structure of the second transport component 50 is not limited to the one described above. In other embodiments, all the second drive wheels 56 in the second transport component 50 may also be spaced apart on the output shaft of the second motor 51.

[0072] In the above embodiments, each group of second transport components 50 has an independently configured second motor 51. In other embodiments, all groups of second transport components 50 may share the same second motor 51. For example, all second drive wheels 56 in all second transport components 50 are spaced apart on the output shaft of the second motor 51.

[0073] As an example, the first conveyor belt 44, the first conveyor belt 47, the second conveyor belt 55, and the second conveyor belt 58 can all be belts, chains, or other conveying structures, and are not specifically limited here. In actual operation, the first motor 41 starts and drives all the first conveyor belts 47 in the first transport assembly 40 to move, thereby enabling the first conveyor belts 47 in the first transport assembly 40 to receive the parts to be flipped from the feeding assembly 20. After the parts to be flipped are flipped 180°, the second motor 51 starts and drives all the second conveyor belts 58 in the second transport assembly 50 to move, thereby enabling the second conveyor belts 58 in the second transport assembly 50 to transport the parts to be flipped outwards.

[0074] In this application, all the first conveyor belts 47 in the first transport assembly 40 cooperate to jointly carry and receive the same item to be flipped, and all the second conveyor belts 58 in the second transport assembly 50 cooperate to jointly carry and transport the same item to be flipped outward. This design improves the stability of the movement of the item to be flipped. Furthermore, a single first motor 41 can drive multiple first conveyor belts 47 within the same group, and a single second motor 51 can drive multiple second conveyor belts 58 within the same group. This design simplifies the structure of the flipping device 100, thereby reducing the manufacturing cost of the flipping device 100.

[0075] Please see Figure 3 In some embodiments, a first clamping cylinder 48 is provided between at least two adjacent second conveyor belts 58 in the first transport component 40, and a second clamping cylinder 59 is provided between at least two adjacent second conveyor belts 58 in the second transport component 50. The first clamping cylinder 48 and the second clamping cylinder 59 are aligned in the vertical direction Z, and the telescopic shafts of the aligned first clamping cylinder 48 and the second clamping cylinder 59 cooperate to clamp the part to be flipped.

[0076] Preferably, in the first transport assembly 40, a first clamping cylinder 48 is further provided between every two adjacent first conveyor belts 47, and in the second transport assembly 50, a second clamping cylinder 59 is further provided between every two adjacent second conveyor belts 58. The number of first clamping cylinders 48 and second clamping cylinders 59 are the same and correspond one-to-one, and the telescopic shafts of the corresponding first clamping cylinders 48 and second clamping cylinders 59 cooperate to clamp the part to be flipped.

[0077] In actual operation, all the first conveyor belts 47 of the first transport component 40 continue to run after receiving the item to be flipped until the item moves between the first clamping cylinder 48 and the second clamping cylinder 59 and is clamped by the first clamping cylinder 48 and the second clamping cylinder 59.

[0078] In this embodiment, all the first clamping cylinders 48 and all the second clamping cylinders 59 in the corresponding first transport component 40 and second transport component 50 cooperate to clamp the same piece to be flipped, so as to ensure that the piece to be flipped will not fall off the flipping component 30 during the 180° rotation process, thereby improving the reliability of the flipping.

[0079] Please see Figure 5In some embodiments, the side circumferential surface of the annular frame 31 is continuously provided with a plurality of teeth 312. The flipping device 100 also includes a drive assembly 60, which includes a flipping motor, a flipping drive wheel 61 and a flipping driven wheel 62. The flipping motor is connected to the flipping drive wheel 61 in a transmission manner, and the flipping driven wheel 62 is engaged between the flipping drive wheel 61 and the teeth 312 of the annular frame 31.

[0080] As an example, the flip motor can be a servo motor, a motor, or other drive structure, which can be set according to the requirements.

[0081] It can be understood that the annular frame 31 is equivalent to an annular gear. When the flipping motor is working, its power can be transmitted to the annular frame 31 in sequence through the flipping drive wheel 61 and the flipping driven wheel 62, thereby driving the first transport component 40, the second transport component 50 and the item to be flipped to rotate 180°, so as to realize the flipping of the item to be flipped.

[0082] The flipping device 100 uses a flipping motor, a flipping drive wheel 61, and a flipping driven wheel 62 to drive the annular frame 31 to rotate, thereby flipping the part to be flipped. The flipping drive wheel 61, the flipping driven wheel 62, and the annular frame 31 have less wear, and the flipping device 100 has a long service life.

[0083] Of course, in other embodiments, the structure of the drive assembly 60 is not limited to the one described above. For example, the drive assembly 60 includes a tilting motor, a tilting drive wheel 61, and a tilting conveyor belt. The annular frame 31 is used as a tilting driven wheel. The tilting drive wheel 61 is fixed on the output shaft of the tilting motor. The tilting conveyor belt is sleeved on the tilting drive wheel 61 and the annular frame 31. When the tilting motor is working, its power is transmitted to the annular frame 31 sequentially through the tilting drive wheel 61 and the tilting conveyor belt, driving the annular frame 31 to rotate. Another example is that the drive assembly 60 includes a tilting motor and a tilting drive wheel 61, with the tilting motor and the tilting drive wheel 61 being drive-connected. The tilting drive wheel 61 meshes with the teeth 312 of the annular frame 31. Yet another example is that the drive assembly 60 includes a tilting motor, with the output shaft of the tilting motor directly drive-connected to the tilting assembly 30. Please refer to [link to relevant documentation]. Figure 1 and Figure 4 In some embodiments, the flipping assembly 30 further includes a first support plate 32, a second support plate 33, a connecting rod 34, and a rotating shaft 35. The first support plate 32 and the second support plate 33 are located in the hollow region 311 of the annular frame 31 and are connected to the annular frame 31. The first support plate 32 and the second support plate 33 are arranged at intervals along the vertical direction Z. The first transport assembly 40 and the second transport assembly 50 are respectively supported on the two surfaces of the first support plate 32 and the second support plate 33 facing each other. The connecting rod 34 is connected between the first support plate 32 and the second support plate 33. One end of the rotating shaft 35 is connected to the connecting rod 34, and the other end of the rotating shaft 35 is rotatably connected to the frame 10.

[0084] In the embodiment where the drive assembly 60 includes a flip motor and the output shaft of the flip motor is directly connected to the flip assembly 30, the flip motor is directly connected to the connecting rod 34.

[0085] The frame 10 includes a connected support rod 11 and a mounting rod 12. The support rod 11 extends in the vertical direction Z, and the mounting rod 12 extends in the first horizontal direction X. The rotating shaft 35 is rotatably connected to the mounting rod 12. The support rod 11 is used to raise the tilting assembly 30 to avoid the tilting assembly 30 from contacting the mounting surface (e.g., the ground) of the mounting frame 10 during rotation and causing scratches. The mounting rod 12 is used to mount the rotating shaft 35 to achieve the rotatable mounting of the tilting assembly 30.

[0086] Specifically, the first transport component 40 is installed on the side of the first support plate 32 facing the second support plate 33, and the second transport component 50 is installed on the side of the second support plate 33 facing the first support plate 32. The first support plate 32 and the second support plate 33 are both located in the hollow area 311 of the annular frame 31 and connected to the annular frame 31. The connecting rod 34 extends in the vertical direction Z and is connected between the first support plate 32 and the second support plate 33. The rotating shaft 35 is fixed on the first connecting rod 34.

[0087] In this embodiment, the rotational installation of the flipping assembly 30 can be achieved through the cooperation of the first bearing plate 32, the second bearing plate 33, the connecting rod 34, the rotating shaft 35 and the annular frame 31, so that the annular frame 31 can be separated from the mounting surface of the mounting frame 10, avoiding the annular frame 31 from contacting the mounting surface and scratching during rotation, thus ensuring the smooth flipping.

[0088] In some embodiments, the flipping device 100 further includes a feeding component, which has the same structure as the feeding component 20, so it will not be described in detail here.

[0089] Among them, the number of feeding components 20, first transport components 40 and second transport components 50 are the same as the number of unloading components, and each corresponds to the unloading component. The unloading component is used to receive the parts to be flipped from the corresponding second transport components 50 after flipping, and to transport the parts to be flipped to the next process.

[0090] This application also provides a solar cell manufacturing production line, which includes the flipping device 100 as described in any of the above embodiments. The solar cell manufacturing production line provided by this application has the effects of any of the above embodiments, and therefore will not be described again here.

[0091] Please see Figure 1The aforementioned flipping device 100 and solar cell manufacturing production line, through the cooperation of the feeding component 20, the flipping component 30, the first transport component 40 and the second transport component 50, can automatically flip the workpiece to be flipped 180°. This flipping method saves time and effort and effectively improves production efficiency.

[0092] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0093] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
