Description

Technical Field

[0001] The utility model relates to the technical field of flipping, in particular to a flipping device and a flipping system. Background Art

[0002] In the production process of photovoltaic modules, glass is needed. Suppliers generally package multiple stacked glasses into a group, and all the glasses in each group are oriented in the same direction. However, the glass groups after packaging may face up or face up with the back relative to the ground, and the directions are not uniform. When unloading, the directions of all the glasses in multiple groups need to be unified, that is, to ensure that all the glasses are placed in the same direction before the actual production of photovoltaic modules.

[0003] In the prior art, each group of packed glasses is usually unpacked first, and then the horizontally placed large glass pieces are placed upright on the glass mounting frame, and then the upright large glass pieces are sucked and flipped 90 degrees by a suction cup to change the direction of the glass. In this way, all the glass pieces are placed in the same direction.

[0004] However, the above method can only flip one piece of glass at a time, and the flipping efficiency is low. Utility Model Content

[0005] The utility model aims to provide a turning device and a turning system for improving the turning efficiency of glass.

[0006] In order to achieve the above-mentioned purpose, in the first aspect, the utility model provides a flipping device. The flipping device is used to flip a workpiece, and the workpiece includes a plurality of parts stacked and placed, and the parts have a first surface and a second surface opposite to each other, and the first surface and the second surface of two adjacent parts are abutted. The above-mentioned flipping device includes: a base frame, a rotating mechanism, a bearing mechanism and a clamping mechanism. The rotating mechanism is rotatably arranged on the base frame, and the rotating mechanism has a accommodating space. The bearing mechanism and the clamping mechanism are both arranged on the rotating mechanism and are located in the accommodating space, and the bearing mechanism and the clamping mechanism are arranged oppositely and at intervals. When the flipping device is in a working state, the bearing mechanism and the clamping mechanism are used to clamp two opposite surfaces of the workpiece. The rotating mechanism is used to flip the bearing mechanism, the clamping mechanism and the workpiece to adjust the direction of the surface of the workpiece relative to the base frame.

[0007] Compared with the prior art, in the turning device provided by the utility model, since the turning device is in a working state, the bearing mechanism and the clamping mechanism are used to clamp the two opposite surfaces of the workpiece. At this time, the bearing mechanism and the clamping mechanism can clamp and fix the workpiece to ensure the safety and stability of the workpiece during the later turning process. Further, since the rotating mechanism is used to turn over the bearing mechanism, the clamping mechanism and the workpiece to adjust the direction of the surface of the workpiece relative to the base frame. At this time, the angle of rotation of the rotating mechanism can be adjusted according to actual needs to adjust the direction of the workpiece relative to the base frame. Exemplarily, when the rotating mechanism drives the workpiece to rotate 180°, the workpiece can be turned from the first surface facing up to the second surface facing up. Since the workpiece includes a plurality of stacked parts, the parts have a first surface and a second surface relative to each other, and the first surface and the second surface of two adjacent parts are abutted. Therefore, when the workpiece is turned from the first surface facing up to the second surface facing up, the orientation of the plurality of parts relative to the base frame changes at the same time. Based on this, compared with the prior art, the turning device provided by the utility model improves the turning speed and turning efficiency.

[0008] In one implementation, the rotating mechanism comprises: a first driving member, a transmission member, a frame and a rotating member. The transmission member is connected to the first driving member, the frame is rotatably arranged on the base frame, the rotating member is arranged on the frame, the rotating member is connected to the transmission member, and the transmission member is used to drive the rotating member to rotate relative to the base frame.

[0009] When the above technical solution is adopted, the above rotating mechanism has a simple structure and is easy to manufacture, assemble and use, thereby improving work efficiency.

[0010] In one implementation, the bearing mechanism includes: a first bearing plate, a second bearing plate and a reset cylinder. The first bearing plate is arranged on the rotating mechanism, and the first bearing plate has a side wall.

The reset cylinder is arranged on the second bearing plate, the reset cylinder has a telescopic end, the telescopic end faces the side wall, and the reset cylinder is used to adjust the position of the second bearing plate relative to the first bearing plate.

[0011] When the above technical solution is adopted, since the reset cylinder is used to adjust the position of the second carrier plate relative to the first carrier plate, the reset cylinder can be used to make the second carrier plate be located in the central area of ​​the first carrier plate or other areas actually required. For example, when the second carrier plate is located in the central area of ​​the first carrier plate, the force on the second carrier plate can be balanced to ensure the stability of the carrier mechanism when carrying the workpiece.

[0012] In one implementation, the above-mentioned bearing mechanism also includes: a first limit plate, a second limit plate, a rolling member and a locking member. The first limit plate is arranged on the first bearing plate, and is located between the first bearing plate and the second bearing plate. The second limit plate is arranged on the second bearing plate, and is located between the first bearing plate and the second bearing plate. The rolling member is limited between the first limit plate and the second limit plate, and the second limit plate is movably connected to the first limit plate through the rolling member, and the rolling member is used to assist in adjusting the position of the second bearing plate relative to the first bearing plate. One end of the locking member is arranged on the first bearing plate, and the other end of the locking member is close to the second bearing plate, and the locking member is used to fix the relative position of the second bearing plate and the first bearing plate.

[0013] When the above technical solution is adopted, since the rolling member is limited between the first limit plate and the second limit plate, when the rotating mechanism flips the bearing mechanism, the rolling member can be prevented from falling off to ensure the normal use of the bearing mechanism. Furthermore, since the rolling member can assist in adjusting the position of the second bearing plate relative to the first bearing plate, under the joint action of the rolling member and the reset cylinder, the position of the second bearing plate relative to the first bearing plate can be quickly adjusted to improve work efficiency. Further, when the position of the second bearing plate relative to the first bearing plate is adjusted into place, the relative position of the second bearing plate and the first bearing plate is fixed by a locking member. At this time, the second bearing plate can be prevented from being displaced relative to the first bearing plate again to ensure that the position of the workpiece placed on the second bearing plate does not change, which is convenient for the clamping mechanism and the first bearing plate to stably clamp the workpiece.

[0014] In one implementation, the clamping mechanism includes: a bottom plate, a pressing plate, and a lifting structure.

[0015] When the above technical solution is adopted, since the lifting structure is used to drive the pressing plate to approach or move away from the bottom plate, the position of the pressing plate can be adjusted according to the thickness of the workpiece to expand the application range of the clamping mechanism. Furthermore, the above clamping mechanism has a simple structure, is easy to manufacture, and is also easy to assemble and use, thereby improving work efficiency.

[0016] In one implementation, the lifting structure includes: a second driving member and a first connecting assembly.

One end of the first connection member is connected to the telescopic drive end, and one end of the adapter is rotatably connected to the other end of the first connection member through a cross connecting shaft. One end of the mounting member is slidably connected to the other end of the adapter along a first direction through a cross roller guide, and one end of the first base is slidably connected to the other end of the mounting member along a second direction through a cross roller guide, the first direction is different from the second direction, and the other end of the first base is arranged on the pressure plate.

[0018] When the above technical solution is adopted, the cross connecting shaft is used to make the first base have two mutually perpendicular rotational degrees of freedom relative to the first connecting member, and then the pressure plate has two mutually perpendicular rotational degrees of freedom relative to the bottom plate, that is, the pressure plate can rotate in two different directions relative to the bottom plate. Furthermore, the above two cross roller guides are used to make the first base have two mutually perpendicular translational degrees of freedom relative to the first connecting member, so that the pressure plate has two mutually perpendicular translational degrees of freedom relative to the bottom plate, that is, the pressure plate can translate in two different directions relative to the bottom plate. In summary, the pressure plate can be adjusted in real time according to the position of the workpiece to be abutted, so as to ensure that the pressure plate can fit the surface of the workpiece, thereby ensuring the stability and safety of the workpiece when the workpiece is clamped in cooperation with the supporting mechanism.

[0023] When the above technical solution is adopted, the cross connecting shaft is used to make the second base have two mutually perpendicular rotational degrees of freedom relative to the second connecting member, and then the pressing plate has two mutually perpendicular rotational degrees of freedom relative to the bottom plate, that is, the pressing plate can rotate in two different directions relative to the bottom plate. At this time, the connecting structure can rotate with the first connecting component, thereby adjusting the angle of the pressing plate relative to the bottom plate.

[0024] In one implementation, the above-mentioned flipping device includes three clamping mechanisms, the bearing mechanism and one of the clamping mechanisms are arranged opposite to each other and spaced apart, and the other two clamping mechanisms are arranged opposite to each other and spaced apart. When the flipping device is in working state, the bearing mechanism and the three clamping mechanisms are used to clamp and fix the four surfaces of the workpiece.

[0025] When the above technical solution is adopted, with the cooperation of the bearing mechanism and the three clamping mechanisms, the safety and stability of the workpiece during the later flipping process can be further ensured, and the relative sliding of the workpiece due to gravity during the flipping process can be reduced or avoided.

[0026] In one implementation, at least one clamping mechanism further includes: a clamping structure and a positioning structure.

One end of the positioning structure is disposed through the bottom plate, and the positioning structure is located outside the lifting structure, the pressure plate, and the clamping structure. When the flipping device is in a working state, the positioning structure is used to abut against one surface of the workpiece to assist the clamping mechanism opposite thereto to abut against another surface of the workpiece, and the two surfaces of the workpiece are relatively distributed.

[0027] When the above technical solution is adopted, the positioning structure is pre-contacted with one surface of the workpiece to apply a supporting force to the workpiece, thereby preventing the workpiece from being displaced due to the thrust from the clamping mechanism when the clamping mechanism opposite to the positioning structure abuts against the other surface of the workpiece.

[0028] In one implementation, the clamping structure includes: a clamping plate and a moving assembly. The clamping plate is arranged opposite to the pressing plate and spaced apart, and is used to abut against the surface of the workpiece.

Further, since the rotating mechanism is used to flip the bearing mechanism, the clamping mechanism and the workpiece to adjust the direction of the surface of the workpiece relative to the base frame. At this time, the angle of rotation of the rotating mechanism can be adjusted according to actual needs to adjust the direction of the workpiece relative to the base frame. Exemplarily, when the rotating mechanism drives the workpiece to rotate 180°, the workpiece can be flipped from the first surface facing up to the second surface facing up. Since the workpiece includes a plurality of stacked parts, the parts have a first surface and a second surface relative to each other, and the first surface and the second surface of two adjacent parts are abutted. Therefore, when the workpiece is flipped from the first surface facing up to the second surface facing up, the orientation of the plurality of parts relative to the base frame changes at the same time.

[0060] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0061] In order to solve the above technical problems, in the first aspect, the embodiment of the utility model provides a flipping device. Figure 1 The flipping device is used to flip a workpiece 1, which includes a plurality of parts 10 stacked together. The parts 10 have a first surface and a second surface opposite to each other, and the first surfaces and the second surfaces of two adjacent parts 10 are in contact with each other.

[0062] For example, see Figure 1 The part 10 may be glass, silicon wafer, photovoltaic module or other structures. Further, the workpiece 1 may also include two trays 11, wherein the stacked parts 10 are horizontally placed in one of the trays 11, and the other tray 11 is buckled on the surface of the part 10 located at the top.

[0063] See also Figure 1 and Figure 2 , the above-mentioned flipping device 2 includes: a base frame 3, a rotating mechanism 4, a bearing mechanism 5 and a clamping mechanism 6. The rotating mechanism 4 is rotatably arranged on the base frame 3, and the rotating mechanism 4 has a accommodating space. The bearing mechanism 5 and the clamping mechanism 6 are both arranged on the rotating mechanism 4, and are located in the accommodating space, and the bearing mechanism 5 and the clamping mechanism 6 are arranged oppositely and at intervals. When the flipping device 2 is in a working state, the bearing mechanism 5 and the clamping mechanism 6 are used to clamp two opposite surfaces of the workpiece 1. The rotating mechanism 4 is used to flip the bearing mechanism 5, the clamping mechanism 6 and the workpiece 1 to adjust the direction of the surface of the workpiece 1 relative to the base frame 3. Exemplarily, the angle at which the above-mentioned rotating mechanism 4 flips the bearing mechanism 5, the clamping mechanism 6 and the workpiece 1 can be 30°, 60°, 90°, 180° or 270°, etc.

[0064] See also Figure 1and Figure 2 In the flipping device 2 provided by the embodiment of the utility model, when the flipping device 2 is in working state, the bearing mechanism 5 and the clamping mechanism 6 are used to clamp the two opposite surfaces of the workpiece 1. At this time, the bearing mechanism 5 and the clamping mechanism 6 can clamp and fix the workpiece 1 to ensure the safety and stability of the workpiece 1 during the later flipping process. Further, since the rotating mechanism 4 is used to flip the bearing mechanism 5, the clamping mechanism 6 and the workpiece 1 to adjust the direction of the surface of the workpiece 1 relative to the base frame 3. At this time, the rotation angle of the rotating mechanism 4 can be adjusted according to actual needs to adjust the direction of the workpiece 1 relative to the base frame 3. Exemplarily, when the rotating mechanism 4 drives the workpiece 1 to rotate 180°, the workpiece 1 can be flipped from the first surface facing up to the second surface facing up. Since the workpiece 1 includes a plurality of stacked parts 10, the part 10 has a first surface and a second surface relative to each other, and the first surface and the second surface of two adjacent parts 10 are abutted. Therefore, when the workpiece 1 is flipped from the first surface facing up to the second surface facing up, the orientation of the plurality of parts 10 relative to the base frame 3 changes simultaneously. Based on this, compared with the prior art, the flipping device 2 provided by the utility model improves the flipping speed and flipping efficiency.

[0065] As a possible implementation, when the first surfaces and second surfaces of any two adjacent parts 10 of the multiple parts 10 included in the workpiece 1 abut against each other, after the workpiece 1 is flipped from the first surface facing upward to the second surface facing upward, the orientations of all parts 10 relative to the base frame 3 are changed simultaneously. At this time, the flipping speed and flipping efficiency can be further improved.

[0066] It should be understood that the multiple parts 10 included in the workpiece 1 can be packaged and fixed together by outer packaging such as packaging paper, packaging bags or fixing plates, or can be simply stacked and placed without being packaged and fixed by packaging. When the multiple parts 10 included in the workpiece 1 are packaged and fixed by packaging, the packaging can be left unpacked when the orientation of the workpiece 1 is adjusted by using the turning device 2, which can not only save time, but also prevent the parts 10 from colliding with each other and preventing the parts 10 from being broken or damaged.

[0067] As a possible implementation, see Figures 1 to 3 The rotating mechanism 4 comprises: a first driving member 40, a transmission member 41, a frame 42 and a rotating member 43. The transmission member 41 is connected to the first driving member 40, the frame 42 is rotatably arranged on the base frame 3, the rotating member 43 is arranged on the frame 42, the rotating member 43 is connected to the transmission member 41, and the transmission member 41 is used to drive the rotating member 43 to rotate relative to the base frame 3. The rotating mechanism 4 has a simple structure, is easy to manufacture, and is also easy to assemble and use, thereby improving work efficiency.

[0068] Exemplarily, the first driving member 40 can be a motor or manually driven. The transmission member 41 can be a gear, the rotating member 43 is a gear ring, and the gear and the gear ring are meshed. Further, the frame 42 includes: a main body 44 and a frame ring 45. The frame ring 45 is arranged at both ends of the main body 44, and the rotating member 43 is arranged on the main body 44, and is located between the two frame rings 45. The base frame 3 includes: a base 30 and a support frame 31. The support frame 31 is provided with a slot, and the frame ring 45 is arranged in the slot, and the frame ring 45 can rotate relative to the support frame 31. In actual use, the motor is connected to the gear power, and the gear and the gear ring are meshed. When the motor drives the gear to rotate, the gear drives the gear ring to rotate, and the gear ring drives the frame 42 to rotate on the base frame 3.

[0069] As a possible implementation, see Figure 1 , Figure 4 and Figure 5 The above-mentioned bearing mechanism 5 includes: a first bearing plate 50, a second bearing plate 51 and a reset cylinder 52. The first bearing plate 50 is arranged on the rotating mechanism 4, and the first bearing plate 50 has a side wall 500. The second bearing plate 51 is opposite to the first bearing plate 50 and is arranged at a distance. The second bearing plate 51 is used to carry the workpiece 1, and the side wall 500 is located at the periphery of the second bearing plate 51. The reset cylinder 52 is arranged on the second bearing plate 51, and the reset cylinder 52 has a telescopic end, which faces the side wall 500. The reset cylinder 52 is used to adjust the position of the second bearing plate 51 relative to the first bearing plate 50.

[0070] When the above technical solution is adopted, since the reset cylinder 52 is used to adjust the position of the second carrier plate 51 relative to the first carrier plate 50, the second carrier plate 51 can be located in the central area of ​​the first carrier plate 50 or other areas actually required by the reset cylinder 52. For example, when the second carrier plate 51 is located in the central area of ​​the first carrier plate 50, the force on the second carrier plate 51 can be balanced to ensure the stability of the carrier mechanism 5 when carrying the workpiece 1.

[0071] In an optional manner, the first bearing plate 50 has four side walls 500, and the bearing mechanism 5 includes four reset cylinders 52, and the telescopic end of each reset cylinder 52 corresponds to a side wall 500. In actual use, the four reset cylinders 52 are all started or partially started, and the telescopic ends of the started reset cylinders 52 extend out and abut against the corresponding side walls. At this time, the reset cylinders 52 drive the second bearing plate 51 to move until the second bearing plate 51 is located in the center area of ​​the first bearing plate 50. For example, when the four reset cylinders 52 are all started, the travel amounts of the telescopic ends in the reset cylinders 52 are equal, and at this time, the second bearing plate 51 is located in the center area of ​​the first bearing plate 50.

[0072] In an alternative approach, see Figure 4 and Figure 5 The above-mentioned bearing mechanism further includes: a first limiting plate 53, a second limiting plate 54, a rolling member 55 and a locking member 56. The first limiting plate 53 is arranged on the first bearing plate 50, and is located between the first bearing plate 50 and the second bearing plate 51. The second limiting plate 54 is arranged on the second bearing plate 51, and is located between the first bearing plate 50 and the second bearing plate 51. The rolling member 55 is limited between the first limiting plate 53 and the second limiting plate 54, and the second limiting plate 54 is movably connected to the first limiting plate 53 through the rolling member 55. The rolling member 55 is used to assist in adjusting the position of the second bearing plate 51 relative to the first bearing plate 50. One end of the locking member 56 is arranged on the first bearing plate 50, and the other end of the locking member 56 is close to the second bearing plate 51. The locking member 56 is used to fix the relative position of the second bearing plate 51 and the first bearing plate 50.

[0073] In the case of adopting the above technical solution, since the rolling member 55 is limited between the first limiting plate 53 and the second limiting plate 54, when the rotating mechanism flips the bearing mechanism 5 by 180°, the rolling member 55 can be prevented from falling off, so as to ensure the normal use of the bearing mechanism 5. Further, since the rolling member 55 can assist in adjusting the position of the second bearing plate 51 relative to the first bearing plate 50, under the joint action of the rolling member 55 and the reset cylinder 52, the position of the second bearing plate 51 relative to the first bearing plate 50 can be quickly adjusted to improve the work efficiency. Further, when the position of the second bearing plate 51 relative to the first bearing plate 50 is adjusted in place, the relative position of the second bearing plate 51 and the first bearing plate 50 is fixed by the locking member 56. At this time, the second bearing plate 51 can be prevented from being displaced again relative to the first bearing plate 50, so as to ensure that the position of the workpiece 1 placed on the second bearing plate 51 does not change, so as to facilitate the clamping mechanism 6 and the first bearing plate 50 to stably clamp the workpiece 1.

[0074] Exemplarily, the longitudinal section of the first limit plate 53 is T-shaped, the longitudinal section of the second limit plate 54 is L-shaped, the fixed end of the rolling element 55 is arranged on the cross bar portion of the L-shaped second limit plate, and the rolling end of the rolling element 55 abuts against the cross bar portion of the T-shaped first limit plate. The rolling element 55 may be a steel ball roller.

[0075] In an optional manner, the rolling member 55 is also arranged between the first bearing plate 50 and the second bearing plate 51, the fixed end of the rolling member 55 is arranged on the first bearing plate 50, the rolling end of the rolling member 55 abuts against the second bearing plate 51, and the second bearing plate 51 can move freely on the rolling member 55.

[0076] In an alternative approach, see Figure 4The locking member 56 may be a locking cylinder, and the piston end of the locking cylinder is connected to the second bearing plate 51. When the second bearing plate 51 moves into place, the locking cylinder is opened, so that the second bearing plate 51 is locked and cannot move freely.

[0077] As a possible implementation, see Figure 1 and Figure 6 , the clamping mechanism 6 includes: a base plate 60, a pressure plate 61 and a lifting structure 62. The base plate 60 is arranged on the rotating mechanism 4, and the pressure plate 61 is opposite to the base plate 60 and is arranged at an interval, and the pressure plate 61 is used to abut against the surface of the workpiece 1. One end of the lifting structure 62 passes through the base plate 60 and is arranged on the pressure plate 61, and the lifting structure 62 is used to drive the pressure plate 61 to approach or move away from the base plate 60. Exemplarily, the pressure plate 61 is a rectangular pressure plate, and the surface of the pressure plate 61 used to abut against the workpiece 1 completely covers or exceeds the abutted surface of the workpiece 1. Furthermore, the clamping mechanism 6 includes four lifting structures 62 distributed along the circumferential direction, at which time the pressure plate 61 can be subjected to balanced force.

[0078] When the above technical solution is adopted, since the lifting structure 62 is used to drive the pressing plate 61 to be close to or away from the bottom plate 60, the position of the pressing plate 61 can be adjusted according to the thickness of the workpiece 1 to expand the application range of the clamping mechanism 6. Furthermore, the above clamping mechanism 6 has a simple structure, is easy to manufacture, and is also easy to assemble and use, thereby improving work efficiency.

[0079] In an alternative approach, see Figure 6 , the above-mentioned lifting structure 62 includes: a second driving member 63 and a first connecting component 64. The second driving member 63 is arranged on the base plate 60, and the second driving member 63 has a telescopic driving end, and the telescopic driving end passes through the base plate 60. One end of the first connecting component 64 is connected to the telescopic driving end, and the other end of the first connecting component 64 is arranged on the pressing plate 61. The second driving member 63 is used to drive the first connecting component 64 and the pressing plate 61 to move closer to or away from the base plate 60, and the first connecting component 64 is used to adjust the position of the pressing plate 61 relative to the base plate 60. Exemplarily, the above-mentioned second driving member 63 can be a compression hydraulic cylinder. In actual use, the four lifting structures 62 are driven by the same type of second driving member 63 to achieve complete fit between the pressing plate 61 and the surface of the workpiece 1.

[0080] In an alternative approach, see Figure 6 and Figure 7The first connecting assembly 64 includes: a first connecting member 640, an adapter 641, a mounting member 642 and a first base 643. One end of the first connecting member 640 is connected to the telescopic driving end, and one end of the adapter 641 is rotatably connected to the other end of the first connecting member 640 through a cross connecting shaft 90. One end of the mounting member 642 is slidably connected to the other end of the adapter 641 along a first direction through a cross roller guide 91, and one end of the first base 643 is slidably connected to the other end of the mounting member 642 along a second direction through a cross roller guide 91. The first direction is different from the second direction, and the other end of the first base 643 is arranged on the pressing plate 61.

[0081] When the above technical solution is adopted, the cross connecting shaft 90 is used to make the first base 643 have two mutually perpendicular rotational degrees of freedom relative to the first connecting member 640, so that the pressure plate 61 has two mutually perpendicular rotational degrees of freedom relative to the bottom plate 60, that is, the pressure plate 61 can rotate in two different directions relative to the bottom plate 60. Further, the above two cross roller guides 91 are used to make the first base 643 have two mutually perpendicular translational degrees of freedom relative to the first connecting member 640, so that the pressure plate 61 has two mutually perpendicular translational degrees of freedom relative to the bottom plate 60, that is, the pressure plate 61 can translate in two different directions relative to the bottom plate 60. In summary, the pressure plate 61 can be adjusted in real time according to the position of the workpiece 1 to be abutted, so as to ensure that the pressure plate 61 can fit with the surface of the workpiece 1, and thus ensure the stability and safety of the workpiece 1 when the workpiece 1 is clamped by the supporting mechanism 5.

[0082] In an alternative approach, see Figure 6 The clamping mechanism 6 comprises a connecting structure 65 . One end of the connecting structure 65 passes through the bottom plate 60 and is disposed on the pressing plate 61 . The lifting structure 62 is located at the periphery of the connecting structure 65 . The connecting structure 65 is used to adjust the angle of the pressing plate 61 relative to the bottom plate 60 .

[0083] When the above technical solution is adopted, on the basis of the lifting structure 62 , the connecting structure 65 can further improve the stability of the pressing plate 61 and ensure the stability of the clamping mechanism 6 .

[0084] In an alternative approach, see Figure 6 The connection structure 65 includes: a ball guide shaft 66 and a second connection component 67. The ball guide shaft 66 is arranged on the bottom plate 60, one end of the ball guide shaft 66 passes through the bottom plate 60 and is connected to one end of the second connection component 67, the other end of the second connection component 67 is arranged on the pressing plate 61, and the second connection component 67 is used to adjust the angle of the pressing plate 61 relative to the bottom plate 60.

[0085] In an alternative approach, see Figure 6 and Figure 8The second connecting assembly 67 includes: a second connecting member 68 and a second base 69. One end of the second connecting member 68 is connected to the end of the ball guide shaft 66, one end of the second base 69 is rotatably connected to the other end of the second connecting member 68 through a cross connecting shaft 90, and the other end of the second base 69 is disposed on the pressing plate 61. Exemplarily, the second connecting member 68 is a universal joint base.

[0086] When the above technical solution is adopted, the cross connecting shaft 90 is used to make the second base 69 have two mutually perpendicular rotational degrees of freedom relative to the second connecting member 68, and then the pressing plate 61 has two mutually perpendicular rotational degrees of freedom relative to the bottom plate 60, that is, the pressing plate 61 can rotate in two different directions relative to the bottom plate 60. At this time, the connecting structure 65 can rotate together with the first connecting component 64, thereby adjusting the angle of the pressing plate 61 relative to the bottom plate 60.

[0087] In an optional manner, the above-mentioned turning device 2 includes three clamping mechanisms 6, the bearing mechanism 5 and one of the clamping mechanisms 6 are arranged opposite to each other and spaced apart, and the other two clamping mechanisms 6 are arranged opposite to each other and spaced apart. When the turning device 2 is in working state, the bearing mechanism 5 and the three clamping mechanisms 6 are used to clamp and fix the four surfaces of the workpiece 1.

[0088] When the above-mentioned technical solution is adopted, with the cooperation of the supporting mechanism 5 and the three clamping mechanisms 6, the safety and stability of the workpiece 1 during the later flipping process can be further ensured, the relative sliding of the workpiece 1 due to gravity during the flipping process of the workpiece 1 can be reduced or avoided, and the workpiece 1 can be prevented from detaching from the flipping device 2.

[0089] For the convenience of description, the other three clamping mechanisms 6 are defined as a clamping mechanism 6, a side clamping mechanism 7 and a lateral clamping mechanism 8. The supporting mechanism 5 and the clamping mechanism 6 are arranged opposite to each other and at intervals, and are used to clamp and fix two surfaces of the workpiece 1 (generally the top surface and the bottom surface of the workpiece 1). The side clamping mechanism 7 and the lateral clamping mechanism 8 are arranged opposite to each other and at intervals, and are used to clamp and fix the other two surfaces of the workpiece 1 (generally the side surfaces of the workpiece 1). In the embodiment of the utility model, the surfaces of the above-mentioned side clamping mechanism 7, the lateral clamping mechanism 8, the clamping mechanism 6 and the supporting mechanism 5 used to abut against the workpiece 1 completely cover or exceed the abutted surface of the workpiece 1.

[0090] In an alternative approach, see Figure 1 and Fig. 9The pressing plate 61 of the lateral clamping mechanism 8 can be a rectangular parallelepiped or a structure with a T-shaped cross section. For example, when the top and bottom surfaces of the stacked multiple parts 10 are both provided with trays 11, the upper and lower areas of the side surface of the workpiece 1 protrude outward compared to the middle area. At this time, the pressing plate 61 is selected to have a T-shaped cross section so as to better fit the side surface of the workpiece 1, thereby ensuring the safety and stability of the workpiece 1 during the later flipping process.

[0091] Furthermore, in actual use, the four lifting structures 62 included in the lateral clamping mechanism 8 are driven by the same type of second driving member 63 to achieve complete fit between the pressing plate 61 and the side surface of the workpiece 1 .

[0092] Furthermore, since the side surface of the workpiece 1 is generally made of glass, the material of the surface of the pressing plate 61 that contacts the workpiece 1 is a soft polyurethane material to prevent the workpiece 1 from being damaged during the flipping process.

[0093] In an alternative approach, see Figure 1 , Fig.10 and Fig.11 , the at least one clamping mechanism (such as the side clamping mechanism 7) further includes: a clamping structure 70 and a positioning structure 71. The clamping structure 70 is arranged on the pressing plate 61, and the clamping structure 70 is used to abut against the surface of the workpiece 1. One end of the positioning structure 71 is arranged through the bottom plate 60, and the positioning structure 71 is located at the periphery of the lifting structure 62, the pressing plate 61 and the clamping structure 70. When the flipping device 2 is in working state, the positioning structure 71 is used to abut against one surface of the workpiece 1 to assist the clamping mechanism 6 opposite thereto to abut against the other surface of the workpiece 1, and the two surfaces of the workpiece 1 are relatively distributed.

[0094] When the above technical solution is adopted, the positioning structure 71 is pre-contacted with one surface of the workpiece 1 so that the workpiece 1 is subjected to a supporting force, thereby preventing the workpiece 1 from being displaced due to the thrust from the clamping mechanism 6 when the clamping mechanism 6 opposite to the positioning structure 71 abuts against the other surface of the workpiece 1.

[0095] In an alternative approach, see Fig.10 and Fig.11 The clamping structure 70 includes: a clamping plate 72 and a moving assembly 73. The clamping plate 72 is arranged opposite to the pressing plate 61 and spaced apart, and is used to abut against the surface of the workpiece 1. The moving assembly 73 is arranged between the clamping plate 72 and the pressing plate 61, and the clamping plate 72 is movably connected to the pressing plate 61 through the moving assembly 73. Exemplarily, the clamping structure 70 includes two clamping plates 72 arranged opposite to each other.

[0096] Furthermore, since the side of the workpiece 1 is generally glass, the material of the side of the clamping plate 72 that contacts the workpiece 1 is a soft polyurethane material to prevent the workpiece 1 from being damaged during the flipping process. Furthermore, in actual use, the four lifting structures 62 are driven by the same type of second driving member 63 to achieve complete contact between the clamping plate 72 and the side of the workpiece 1.

[0097] In an alternative approach, see Fig.10 and Fig.11 The moving assembly 73 includes: a first moving assembly 74. The first end of the first moving assembly 74 is disposed on the pressing plate 61, and the second end of the first moving assembly 74 is rotatably disposed on the pressing plate 72. The first moving assembly 74 is used to drive the pressing plate 72 to move along the third direction or the fourth direction, the third direction is different from the fourth direction, and the third direction and the fourth direction are both parallel to the pressing plate 72.

[0098] When adopting the above technical solution, the first moving component 74 can be used to make the clamping plate 72 rotate relative to the pressure plate 61 or translate in two different directions. At this time, the clamping plate 72 can be adjusted in real time according to the position of the workpiece 1 to be abutted to ensure that the clamping plate 72 can fit the surface of the workpiece 1, thereby ensuring the stability and safety of the workpiece 1 when clamping the workpiece 1.

[0099] In an alternative approach, see Fig.11 and Fig.12 The first moving assembly 74 includes: a third driving member 740, a bidirectional screw rod 741 and a third connecting assembly 742. The third driving member 740 is connected to one end of the bidirectional screw rod 741, and is used to drive the bidirectional screw rod 741 to move. The nut 7410 of the bidirectional screw rod 741 is connected to one side of the third connecting assembly 742, and is used to drive the third connecting assembly 742 to move. One end of the third connecting assembly 742 is set on the pressing plate 61, and the other end of the third connecting assembly 742 is rotatably set on the pressing plate 72.

[0100] Exemplarily, the third driving member 740 may be a servo motor, the bidirectional screw rod 741 may be a ball screw, and the servo motor is connected to the ball screw rod via a coupling 93 .

[0101] In an alternative approach, see Fig.11 and Fig.12The third connecting assembly 742 includes: a third connecting member 743, a fourth connecting member 744, a fifth connecting member 745 and a first bearing 746. One side of the third connecting member 743 is arranged on the pressure plate 61, one side of the fourth connecting member 744 is slidably connected with the other side of the third connecting member 743 along the third direction through the cross roller guide 91, the nut of the bidirectional screw rod 741 is connected with the fourth connecting member 744, and the third direction is consistent with the length direction of the bidirectional screw rod 741. One side of the fifth connecting member 745 is slidably connected with the other side of the fourth connecting member 744 along the fourth direction through the cross roller guide 91, and the first bearing 746 is rotatably connected with the other side of the fifth connecting member 745 and the pressure plate 72 respectively.

[0102] When the above technical solution is adopted, the first bearing 746 has two mutually perpendicular translational degrees of freedom relative to the third connecting member 743, and the clamping plate 72 can translate in two different directions relative to the clamping plate 61. Further, the clamping plate 72 can rotate relative to the clamping plate 61 by using the first bearing 746. In summary, the position of the clamping plate 72 relative to the workpiece 1 can be adjusted so that the clamping plate 72 is aligned with the workpiece 1 and the force on the clamping plate 72 is balanced.

[0103] In an alternative approach, see Fig.10 The side clamping mechanism 7 further includes: two sensors 75. The two sensors 75 are mounted on the clamping plate 72, and each sensor 75 corresponds to the position of each first moving assembly 74. In actual use, when the sensor 75 detects that it is in place, the third driving member 740 of the first moving assembly 74 corresponding to the sensor 75 stops working.

[0104] In an alternative approach, see Fig.11 and Fig.13 The above-mentioned moving assembly 73 further includes: a second moving assembly 76. The first end of the second moving assembly 76 is disposed on the pressing plate 61, and the second end of the second moving assembly 76 is rotatably disposed on the clamping plate 72, and the second moving assembly 76 is used to drive the two clamping plates 72 to move closer to or away from each other.

[0105] When the above technical solution is adopted, the distance between the two clamping plates 72 can be adapted to workpieces 1 of different sizes, so as to expand the applicable range of the moving assembly 73 .

[0106] In an alternative approach, see Fig.11 and Fig.13The second moving assembly 76 includes a sixth connecting member 760, a seventh connecting member 761 and a second bearing 762. One side of the sixth connecting member 760 is disposed on the pressure plate 61, and the other side of the sixth connecting member 760 is slidably connected to one side of the seventh connecting member 761 through a cross roller guide 91, and the second bearing 762 is rotatably connected to the other side of the seventh connecting member 761 and the pressure plate 72 respectively.

[0107] When the above technical solution is adopted, the second bearing 762 has one translational freedom and one rotational freedom relative to the sixth connecting member 760. At this time, the clamping plate 72 can rotate and translate relative to the clamping plate 61 to cooperate with the first moving assembly 74 to adjust the position of the clamping plate 72 relative to the workpiece 1, so that the clamping plate 72 is aligned with the workpiece 1 and the force on the clamping plate 72 is balanced.

[0108] In an alternative approach, see Fig.10 The side clamping mechanism 7 further includes a steel ball roller 92, the fixed end of which is arranged on the pressing plate 61, and the rolling end of which is in contact with the pressing plate 72. Under the joint action of the steel ball roller and the moving assembly 73, the position of the pressing plate 72 relative to the pressing plate 61 can be quickly adjusted.

[0109] In an alternative approach, see Fig.10 The positioning structure 71 includes: a fourth driving member 710 and a positioning member 711. The fourth driving member 710 is disposed on the bottom plate 60, and the fourth driving member 710 has a telescopic driving end, and the telescopic driving end penetrates the bottom plate 60. One end of the positioning member 711 is connected to the telescopic driving end, and the fourth driving member 710 is used to drive the positioning member 711 to approach or move away from the bottom plate 60.

[0110] For example, the fourth driving member 710 may be a cylinder, and the positioning member 711 may be a positioning guide wheel. In actual use, the guide wheel end of the positioning guide wheel is used to abut against the surface of the workpiece 1.

[0111] The specific use process of the flip device is described below by taking a possible implementation as an example. It should be understood that the following description is only for understanding and is not intended to be a specific limitation.

[0112] See also Figures 1 to 13 First, a plurality of stacked parts 10 are horizontally placed in one of the trays 11, and another tray 11 is buckled onto the surface of the topmost part 10, thereby forming a workpiece 1 to be flipped.

[0113] Next, the workpiece 1 is placed on the second bearing plate 51. At the same time, the telescopic end of the reset cylinder 52 is retracted and located in the cylinder body. The locking member 56 releases the second bearing plate 51, so that the second bearing plate 51 is in a free state.

[0114] Next, the positioning structure 71 included in the side clamping mechanism 7 is activated, and the fourth driving member 710 drives the positioning member 711 to approach the first side of the workpiece 1. When the positioning member 711 abuts against the first side of the workpiece 1, the side clamping mechanism 8 is activated, and the pressing plate 61 included in the side clamping mechanism 8 approaches and completely fits the second side of the workpiece 1. When the pressing plate 61 completely fits the second side of the workpiece 1, the second driving members 63 of the four lifting structures 62 included in the side clamping mechanism 8 are locked.

[0115] Next, the second driving members 63 of the four lifting structures 62 included in the side clamping mechanism 7 drive the pressing plate 61 to approach the first side of the workpiece 1 with a very small force until the pressing plate 72 connected to the pressing plate 61 is in close contact with the first side of the workpiece 1 .

[0116] Next, the second driving members 63 of the four lifting structures 62 included in the side clamping mechanism 7 respectively inject a certain volume of hydraulic oil in the reverse direction, so that the four second driving members 63 move backward a small distance at the same time, so that the clamping plate 72 is parallel to the first side of the workpiece 1 but not in contact.

[0117] Next, the four first moving components 74 included in the side clamping mechanism 7 respectively drive the two clamping plates 72 to move away from each other. When the corresponding sensors 75 detect that they are in position, the four first moving components 74 stop moving. At this time, the two clamping plates 72 do not exceed the upper and lower edges of the workpiece 1, and the distance between the clamping plate 72 and the first side surface of the workpiece 1 is less than the thickness of a single glass.

[0118] Next, the second driving members 63 of the four lifting structures 62 included in the side clamping mechanism 7 are respectively injected with hydraulic oil from the front side with very small pressure to make the clamping plate 72 close to the first side of the workpiece 1 again. Then, the four second driving members 63 are locked. Then, the locking member 56 of the supporting mechanism 5 is opened to lock the second supporting plate 51.

[0119] Next, the pressing mechanism 6 opposite to the carrying mechanism 5 is started. The second driving members 63 of the four lifting structures 62 included in the pressing mechanism 6 are supplied with oil using the same hydraulic source, so that the pressing plate 61 is in close contact with the tray 11 .

[0120] When the pressing plate 61 in the clamping mechanism 6 is in close contact with the pallet 11, the first driving member 40 (motor) drives the transmission member 41 (gear) to rotate, and the gear drives the rotating member 43 (gear ring) to rotate, so that the gear ring drives the frame 42 to rotate 180° on the base frame 3, and then drives the supporting mechanism 5, the clamping mechanism 6, the side clamping mechanism 7, the lateral clamping mechanism 8 and the workpiece 1 to rotate 180° on the base frame 3.

[0121] After the rotation is completed, the side clamping mechanism 7 and the lateral clamping mechanism 8 are retracted, and then the clamping mechanism 6 is lowered. The staff takes out the turned workpiece 1, and the turning of the workpiece 1 is completed.

[0122] In a second aspect, the embodiment of the utility model further provides a flipping system, which is applied in the preparation process of solar cells. The flipping system includes a control device and the flipping device described in the above technical solution, and the control device is communicatively connected or electrically connected to the flipping device. The flipping device is used to flip a workpiece, and the workpiece includes a plurality of parts stacked and placed, and the parts include: any one of glass, silicon wafers or photovoltaic modules.

[0123] The flipping system provided by the embodiment of the utility model includes a flipping device. When the flipping device is in a working state, the bearing mechanism and the clamping mechanism are used to clamp the two opposite surfaces of the workpiece. At this time, the bearing mechanism and the clamping mechanism can clamp and fix the workpiece to ensure the safety and stability of the workpiece during the later flipping process. Further, since the rotating mechanism is used to flip the bearing mechanism, the clamping mechanism and the workpiece to adjust the direction of the surface of the workpiece relative to the base frame. At this time, the angle of rotation of the rotating mechanism can be adjusted according to actual needs to adjust the direction of the workpiece relative to the base frame. Exemplarily, when the rotating mechanism drives the workpiece to rotate 180°, the workpiece can be flipped from the first surface facing up to the second surface facing up. Since the workpiece includes a plurality of stacked parts, the parts have a first surface and a second surface relative to each other, and the first surface and the second surface of two adjacent parts are abutted. Therefore, when the workpiece is flipped from the first surface facing up to the second surface facing up, the orientation of the plurality of parts relative to the base frame changes simultaneously. Based on this, compared with the prior art, the flipping device provided by the embodiment of the utility model improves the flipping speed and flipping efficiency.

[0124] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0125] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
