The beam positioning sleeve 10183 is provided with a second positioning pin (not shown in the figure). After the beam 10181 is adjusted to a target height, the beam 10181 is fixed at the target height through cooperation of the second positioning pin and the second positioning hole 10185.

[0059] In a specific application scenario, in the process of placing the thin plate segment to be turned over on the turning-over device 10, it is necessary to first adjust the clamping trolley to a position that can adapt to the lifting lug according to the distribution of the lifting lug on the thin plate segment to be turned over and other related parameters, such as the existence of some protruding parts on the thin plate segment to be turned over; first, the trolley frame 1010 is moved to the target position by cooperating the walking assembly 1011 with the walking track 10013, and then the position of the U-shaped clamp is adjusted in the first direction, the second direction and the third direction by the first driving member 1014, the second driving member 1015 and the third driving member 1016 in the position adjusting assembly; before the carrying device 20 places the thin plate segment on the turning-over platform 100, the horizontal beams 10181 in the receiving assembly 1018 of each clamping trolley should be adjusted to the same horizontal height by the horizontal beam oil cylinder 10182, and then all the horizontal beams 10181 at the same horizontal height jointly support the thin plate segment when the carrying device 20 places the thin plate segment on all the horizontal beams 10181, and in the process of placing the thin plate segment on the horizontal beams 10181, the lifting lug should be inserted between the two clamping plates 10120 of the corresponding U-shaped clamp, and then the position of the U-shaped clamp and the corresponding lifting lug is fixed by the third positioning pin 10122 passing through the third positioning hole 10123 of one clamping plate 10120, the lug hole of the lifting lug and the third positioning hole 10123 of the other clamping plate 10120 in turn, so as to clamp and fix the lifting lug. It can be understood that in the process of placing the thin plate segment on the horizontal beams 10181, the lifting lug may not be completely inserted between the two clamping plates 10120 of the corresponding U-shaped clamp, or the lug hole of the lifting lug and the third positioning hole 10123 on the two clamping plates 10120 cannot be completely aligned, at which time the position of the U-shaped clamp can be adjusted again in the first direction, the second direction and the third direction by the first driving member 1014, the second driving member 1015 and the third driving member 1016 in the position adjusting assembly, so that the lifting lug is inserted between the two clamping plates 10120 of the corresponding U-shaped clamp, and the lug hole of the lifting lug and the third positioning hole 10123 on the two clamping plates 10120 are completely aligned.

[0060] III. Lifting of the thin plate segment.

[0061] The turning-over device 10 of the present application also comprises a lifting device 102, which is used to lift the turning-over platform 100, the clamping device 101 on the turning-over platform 100 and the thin plate segment clamped and fixed by the clamping device 101 as a whole, to provide further preparation for turning over the thin plate segment.

[0062] For example, the lifting device 102 comprises lifting beams 1021 arranged at the sides of the turnover platform 100, the lifting beams 1021 are connected to the middle positions of the sides of the turnover platform 100 through rotating shafts 1022; the lifting device 102 can lift or lower the lifting beams 1021 to drive the turnover platform 100 connected to the lifting beams 1021 and the thin plate segments to be turned over fixed on the turnover platform 100 to rise or fall together. In the present application, the middle positions of the sides of the turnover platform 100 connected by the rotating shafts 1022 refer to the middle regions of the sides of the turnover platform 100, and are not limited to the positions in the middle.

[0063] In a specific embodiment, please refer to Figures 2 to 5 , the lifting device 102 comprises four columns 1020 arranged at the four corners of the periphery of the turnover platform 100 and two lifting beams 1021 arranged in parallel with the second frame beams 10011 and arranged at the two sides of the turnover platform 100, each of the two lifting beams 1021 is located between the two columns 1020 close to one side thereof, and the middle positions of the two lifting beams 1021 are respectively connected to the positions corresponding to the ends of the first frame beams 10010 in the middle of the turnover platform 100 through rotating shafts 1022, and each of the columns 1020 is further provided with a lifting driving assembly 1023, and the ends of the two lifting beams 1021 are connected to the lifting driving assemblies 1023 of the corresponding columns 1020, and the four lifting driving assemblies 1023 are used to lift or lower the two lifting beams 1021 along the columns 1020 and drive the turnover platform 100 connected to the lifting beams 1021 through the rotating shafts 1022 to rise or fall together. In addition, the sides of the four columns 1020 are provided with inclined pull rods 1024, which are used to support the columns 1020 to keep them in an upright state and prevent them from tilting to ensure the safe operation of the lifting device 102.

[0064] It can be understood that, when the lifting driving assemblies 1023 lift or lower the two lifting beams 1021 and the turnover platform 100, in order to keep the turnover platform 100 balanced, a connecting assembly can also be arranged between the second frame beams 10011 of the turnover platform 100 and the lifting beams 1021, and the structure of the connecting assembly is not limited here, for example, it can be a temporarily arranged rope or a welded plate, etc.

[0065] Further, the lifting driving assembly 1023 can include a fixed pulley set 10230, a movable pulley set 10231, a steel wire rope 10232, and a lifting winch 10233, wherein the fixed pulley set 10230 is fixedly arranged at the top of the stand column 1020, the movable pulley set 10231 is fixedly connected with the end of the corresponding lifting beam 1021, the fixed pulley set 10230 and the movable pulley set 10231 are connected through the steel wire rope 10232, and the steel wire rope 10232 is connected with the lifting winch 10233. The lifting beam 1021 fixedly connected with the movable pulley set 10231 is lifted by winding the steel wire rope 10232 through the lifting winch 10233, so as to realize the lifting of the sheet segment on the turnover platform 100.

[0066] IV. Turnover process of the sheet segment

[0067] The turnover equipment 10 of the present application further includes a turnover driving device 103. After the lifting device 102 lifts the turnover platform 100, the clamping device 101 on the turnover platform 100, and the sheet segment clamped and fixed by the clamping device 101 as a whole to a preset height, the turnover driving device 103 can drive the turnover platform 100 to rotate 180 degrees around the rotation shaft 1022 relative to the lifting beam 1021, so as to realize the turnover of the sheet segment.

[0068] Please refer to Figures 2 to 6c wherein, Figures 6a to 6cis a schematic view of the turning-over process of the turning-over device 10. It can be understood that, since the turning-over platform 100 is turned over 180 degrees around the rotation shaft 1022 after being lifted to a preset height, when the turning-over platform 100 is rotated 90 degrees around the rotation shaft 1022, the end of the turning-over platform 100 facing downward is closest to the ground, and at this time, the point closest to the ground should not contact the ground. Since the rotation shaft 1022 is connected to the position corresponding to the end of the first frame beam 10010 in the middle of the turning-over platform 100, that is, the preset height should be greater than half the length of the second frame beam 10011, so as to ensure that the turning-over platform 100 does not collide with the ground during the process of being turned over 180 degrees around the rotation shaft 1022 after being lifted to the preset height. The application can be provided with a height detector (not shown in the figure) on the lifting device 102, for example, on the bottom of the lifting beam 1021. When the lifting beam 1021 is lifted to a certain height, the height detector can detect the height of the lifting beam 1021 from the ground. When it is detected that the height of the lifting beam 1021 from the ground is less than or equal to half the length of the second frame beam 10011, the lifting device 102 continues to lift the lifting beam 1021, so as to ensure that the height of the turning-over platform 100 is greater than half the length of the second frame beam 10011 when the turning-over platform 100 is lifted to the preset height. In addition, a height detector can be arranged at the bottom of each lifting beam 1021, and four height detectors are used to detect whether the heights of the two ends of the two lifting beams 1021 are consistent during the lifting or lowering of the two lifting beams 1021, that is, to ensure that the turning-over platform 100 maintains the same height at the four corners during the lifting process.

[0069] The turnover driving device 103 of the present application comprises two rotating discs 1030 and four turnover cylinders 1031, each rotating disc 1030 is sleeved on a rotating shaft 1022, the rotating disc 1030 rotates coaxially with the rotating shaft 1022 on which it is sleeved, at least two connecting holes (not shown in the figure) are arranged on each rotating disc 1030, two turnover cylinders 1031 are arranged on each lifting beam 1021, each turnover cylinder 1031 comprises a turnover cylinder sleeve 10310 and a turnover cylinder telescopic rod 10311, the turnover cylinder telescopic rod 10311 is inserted into the turnover cylinder sleeve 10310 and can move as a piston, the end of the turnover cylinder sleeve 10310 away from the turnover cylinder telescopic rod 10311 is hinged to the lifting beam 1021, the end of the turnover cylinder telescopic rod 10311 away from the turnover cylinder sleeve 10310 is connected to one connecting hole on the corresponding rotating disc 1030, the rotating disc 1030 and the turnover cylinder telescopic rod 10311 can rotate around the connecting hole, that is, the rotating disc 1030 and the turnover cylinder telescopic rod 10311 are connected in rotation around the connecting hole as the axis, the installation positions of the four turnover cylinders 1031 are symmetric about the first frame beam 10010 in the middle of the turnover platform 100, the four turnover cylinders 1031 are used to apply a pushing force or a pulling force to the two rotating discs 1030, so that the rotating discs 1030 rotate and drive the rotating shafts 1022 on which the rotating discs 1030 are sleeved to rotate coaxially, thereby making the turnover platform 100, the clamping device 101 on the turnover platform 100 and the thin plate segment clamped and fixed by the clamping device 101 rotate as a whole, and finally the thin plate segment can be rotated by 180 degrees to realize the turnover of the thin plate segment.

[0070] As an implementable manner, the distances from the connecting holes on the rotating disc 1030 to the center of the rotating shaft 1022 on which the rotating disc 1030 is sleeved are all equal.

[0071] As another implementable manner, three connecting holes are arranged on each rotating disc 1030, and the included angle between any two connecting holes on the rotating disc 1030 and the line connecting the center of the rotating shaft 1022 on which the rotating disc 1030 is sleeved is 120 degrees.

[0072] The specific turnover process of the turnover platform 100 and the thin plate segment will be explained below. Figures 2 to 6c The specific turnover process of the turnover platform 100 and the thin plate segment will be explained below. Figure 6aAfter the lifting device 102 lifts the tilting platform 100, the clamping device 101 on the tilting platform 100, and the thin plate clamped and fixed by the clamping device 101 as a whole to the preset height, the tilting cylinder 1031 on the left side begins to retract, and at the same time, the tilting cylinder 1031 on the right side also begins to retract. At this time, the tilting cylinder 1031 on the left side applies a pulling force to the rotating disk 1030, and the tilting cylinder 1031 on the right side also applies a pulling force to the rotating disk 1030. Since the distance from the connecting hole on the rotating disk 1030 to the center of the rotating shaft 1022 on which the rotating disk 1030 is mounted is equal, and the distance from any two connecting holes on the rotating disk 1030 to the center of the rotating shaft 1022 on which the rotating disk 1030 is mounted is equal, the distance from any two connecting holes on the rotating disk 1030 to the center of the rotating shaft 1022 on which the rotating disk 1030 is mounted is equal. The included angle between the connecting lines is 120 degrees. Therefore, the pulling force applied by the left-side tilting cylinder 1031 to the rotating disk 1030 and the pulling force applied by the right-side tilting cylinder 1031 to the rotating disk 1030 both generate a torque that causes the rotating disk 1030 to rotate counterclockwise around the rotating shaft 1022. Therefore, the rotating disk 1030 can rotate counterclockwise around the rotating shaft 1022. Since the rotating disk 1030 rotates coaxially with its mounted rotating shaft 1022, the rotating shaft 1022 can also rotate counterclockwise, thereby driving the tilting platform 100 connected to the rotating shaft 1022, the clamping device 101 on the tilting platform 100, and the thin plate segment clamped and fixed by the clamping device 101 to rotate counterclockwise as a whole around the rotating shaft 1022. When the rotation reaches the first position, as... Figure 6b As shown, at this time, the intersection of the extension direction of the tilting cylinder telescopic rod 10311 of the right tilting cylinder 1031 and the vertical direction passing through the center of the rotating shaft 1022 is located above the center of the rotating shaft 1022. While the left tilting cylinder 1031 continues to retract, the right tilting cylinder 1031 begins to extend. At this time, the left tilting cylinder 1031 applies a pulling force to the rotating disk 1030, while the right tilting cylinder 1031 applies a pushing force to the rotating disk 1030. Because the extension direction of the tilting cylinder telescopic rod 10311 of the right tilting cylinder 1031 intersects the vertical direction passing through the center of the rotating shaft 1022, the extension direction of the right tilting cylinder telescopic rod 1031 is above the center of the rotating shaft 1022. The intersection point in the vertical direction is located above the center of the rotation axis 1022. Therefore, the pulling force applied by the left-side tilting cylinder 1031 to the rotating disk 1030 and the pushing force applied by the right-side tilting cylinder 1031 to the rotating disk 1030 both generate a torque that causes the rotating disk 1030 to rotate counterclockwise around the rotation axis 1022. Thus, the rotating disk 1030 can continue to rotate counterclockwise around the rotation axis 1022, thereby driving the tilting platform 100 connected to the rotation axis 1022, the clamping device 101 on the tilting platform 100, and the thin plate segment clamped and fixed by the clamping device 101 to continue to rotate counterclockwise around the rotation axis 1022 as a whole. When the rotation continues to reach the second position, as Figure 6cAs shown, at this time, the intersection of the extension direction of the turning cylinder telescopic rod 10311 of the left turning cylinder 1031 and the vertical direction passing through the center of the rotating shaft 1022 is below the center of the rotating shaft 1022, at this time, the extension of the right turning cylinder 1031 is continued to be kept, and the extension of the left turning cylinder 1031 is also started to be adjusted, at this time, the right turning cylinder 1031 applies a pushing force to the rotating disc 1030, and the left turning cylinder 1031 also applies a pushing force to the rotating disc 1030, since the intersection of the extension direction of the turning cylinder telescopic rod 10311 of the left turning cylinder 1031 and the vertical direction passing through the center of the rotating shaft 1022 is below the center of the rotating shaft 1022, therefore, the pushing force applied by the left turning cylinder 1031 to the rotating disc 1030 and the pushing force applied by the right turning cylinder 1031 to the rotating disc 1030 both generate a torque that makes the rotating disc 1030 rotate counterclockwise around the rotating shaft 1022, so that the rotating disc 1030 can continue to rotate counterclockwise around the rotating shaft 1022, and further drive the turnover platform 100 connected with the rotating shaft 1022, the clamping device 101 on the turnover platform 100 and the thin plate segment clamped and fixed by the clamping device 101 as a whole to continue to rotate counterclockwise around the rotating shaft 1022, and until the rotating shaft 1022 is rotated counterclockwise by 180 degrees, the extension and retraction of all turning cylinders 1031 are stopped, and the turnover work of the thin plate segment is completed. It can be understood that during the turning process, the extension direction of the left turning cylinder 1031 and the extension direction of the right turning cylinder 1031 do not pass through the center of the rotating shaft 1022 at the same time, so that it can be ensured that during the extension and retraction process of the left turning cylinder 1031 and the right turning cylinder 1031, at least the extension force of one of the cylinders to the rotating disc 1030 can generate a torque that makes the rotating disc 1030 rotate around the rotating shaft 1022, that is, there is no case that the forces cannot make the rotating disc 1030 rotate along the direction of the center of the rotating shaft 1022.

[0073] Please combine Figures 7 to 12As an implementation manner, the clamping trolley further comprises a protection assembly 1019, which comprises at least two wall self-locking lead screws 10190 and a cross beam wall 10191; the wall self-locking lead screws 10190 are arranged in the second direction through the cross beam 10181, each wall self-locking lead screw 10190 is fixedly connected with the cross beam wall 10191 at one end close to the U-shaped clamp, and the other end is connected with a lateral transmission motor 10192, and the cross beam wall 10191 is arranged in parallel with the cross beam 10181. In the process of fixing the thin plate segments, after the third positioning pin 10122 sequentially passes through the third positioning hole 10123 of one clamping plate 10120, the ear hole of the lifting lug and the third positioning hole 10123 of another clamping plate 10120, and the position of the U-shaped clamp and the corresponding lifting lug is fixed, each lateral transmission motor 10192 should be driven to drive the corresponding wall self-locking lead screw 10190 to rotate, so that the cross beam wall 10191 fixedly connected with the wall self-locking lead screw 10190 at one end close to the U-shaped clamp abuts against the side surface of the U-shaped clamp. It can be understood that all the clamping trolleys of the present application are arranged in the same direction, and when they are turned by 90 degrees, all the cross beam walls 10191 should be turned to the lower side of the U-shaped clamp. Since the fixing mode of the lifting lug of the thin plate segment and the U-shaped clamp in the present application is mechanical pinning, in the process of turning the thin plate segment by 180 degrees, the lifting oil cylinder 10161 of the U-shaped clamp has small gravity of the thin plate segment in the direction perpendicular to the lifting oil cylinder 10161 in the early stage of turning, but has large gravity of the thin plate segment in the direction perpendicular to the lifting oil cylinder 10161 in the middle and late stages of turning. By abutting the cross beam wall 10191 against the side surface of the U-shaped clamp, and in the middle and late stages of turning, the cross beam wall 10191 should be located below the U-shaped clamp, so that the gravity of the thin plate segment in the direction perpendicular to the lifting oil cylinder 10161 originally borne by the lifting oil cylinder 10161 of the U-shaped clamp in the middle and late stages of turning is mainly borne by the cross beam wall 10191, thereby avoiding damage to the lifting oil cylinder 10161 of the U-shaped clamp.

[0074] Further, the protection assembly 1019 further comprises at least two lateral strong guide rods 10193, each end of the cross beam wall 10191 is provided with at least one lateral strong guide rod 10193, one end of the lateral strong guide rod 10193 is connected with the cross beam 10181, and the other end is connected with the cross beam wall 10191, and the at least two lateral strong guide rods 10193 are used to bear the gravity of the thin plate segment on the cross beam wall 10191 in the turning process.

[0075] Further, in order to make the thin plate segments originally borne by the lifting oil cylinder 10161 of the U-shaped clamp in the middle and later stages of the turnover mainly bear the gravity of the thin plate segments in the direction perpendicular to the lifting oil cylinder 10161 by the cross beam abutment 10191, a notch 10124 can be formed on the U-shaped clamp at the position where the cross beam abutment 10191 abuts against the side surface of the U-shaped clamp. When the cross beam abutment 10191 abuts against the side surface of the U-shaped clamp, it can further abut against the side surface position of the notch 10124, and the U-shaped clamp is lifted by the lifting oil cylinder 10161 of the U-shaped clamp so that the bottom surface position of the notch 10124 of the U-shaped clamp abuts against the lower surface of the cross beam abutment 10191.

[0076] V. Transfer of the thin plate segments after the turnover is completed.

[0077] The lifting device 102 in the turnover equipment 10 of the present application is also used to lower the turnover platform 100, the clamping device 101 on the turnover platform 100 and the thin plate segments clamped and fixed by the clamping device 101 as a whole, and to realize the transfer of the thin plate segments after the turnover is completed by the transport vehicle 30 in the thin plate segment turnover system.

[0078] The following will be described in combination with Figures 1 to 12In a specific embodiment, after the rotating disc 1030 is rotated and the rotating shaft 1022 sleeved with the rotating disc 1030 is coaxially rotated by applying a pushing force or a pulling force to the rotating disc 1030 through the turnover cylinder 1031, the turnover platform 100, the clamping device 101 on the turnover platform 100 and the sheet segment clamped and fixed by the clamping device 101 are rotated as a whole, and finally the sheet segment is turned over by 180 degrees, the transport vehicle 30 is first driven to a specified position below the turnover platform 100, at this time, the transport vehicle 30 can carry a rack for placing the sheet segment; then the brake of the lifting winch 10233 is released, the steel wire rope 10232 is retracted in the reverse direction to slowly lower the lifting beam 1021 fixedly connected with the movable pulley set 10231, and the turnover platform 100, the clamping device 101 on the turnover platform 100 and the sheet segment clamped and fixed by the clamping device 101 are slowly lowered until the sheet segment is stably placed on the transport vehicle 30. The position of the U-shaped clamp in the third direction is adjusted by the third driving member 1016, the third positioning pin 10122 is withdrawn from the third positioning hole 10123 and the ear hole of the lifting lug after the third positioning pin 10122 does not bear downward pressure, the second positioning pin is withdrawn from the second positioning hole 10185, and the position between the cross beam abutment 10191 and the U-shaped clamp is adjusted by driving the abutment self-locking screw 10190 by the lateral transmission motor 10192, the pressure between the cross beam abutment 10191 and the U-shaped clamp is released, and the height of the cross beam 10181 is adjusted by the cross beam cylinder 10182 to retract the cross beam 10181, and the complete separation of the sheet segment and the clamping trolley is completed. Then the steel wire rope 10232 is wound by the lifting winch 10233 to lift the lifting beam 1021 fixedly connected with the movable pulley set 10231, the turnover platform 100 is lifted to the preset height again, and at the same time, the transport vehicle 30 can transport the turned-over sheet segment to the next station to realize the transfer of the turned-over sheet segment.

[0079] Six, resetting of the turnover device 10 after the transfer of the sheet segment.

[0080] The turnover driving device 103 in the turnover device 10 of the present application is further used to continue to drive the turnover platform 100 to rotate 180 degrees around the rotating shaft 1022 relative to the lifting beam 1021, so as to realize the resetting of the turnover platform 100 after turnover, and lower the reset turnover platform 100 to the stable contact between the turnover platform 100 and the ground by the lifting device 102 in the turnover device 10, thereby completing the resetting of the turnover device 10 after the transfer of the sheet segment.

[0081] The related work flow and details are described above in the first to fifth aspects, which will not be repeated here.

[0082] It can be understood that the turnover device 10 in the thin plate segmented turnover system does not necessarily include all the devices mentioned above, for example, the turnover platform 100, the clamping device 101, the lifting device 102, and the turnover driving device 103, and each device does not necessarily include all the components or parts thereof, and all the components or parts thereof can be set according to the work required by the respective device; correspondingly, the thin plate segmented turnover system can only include part of the above six aspects to realize the turnover of the thin plate, for example, the thin plate segmented turnover system can only include the second to fourth aspects, and at this time the thin plate segmented turnover system can only include the turnover device 10.

[0083] The functions and methods that can be realized by the thin plate segmented turnover system, the turnover device 10, and the clamping trolley will be described in detail below.

[0084] An embodiment of the thin plate segmented turnover method provided by the present application is described below. Please refer to Figure 13 , Figure 13 is a flowchart of an embodiment of the thin plate segmented turnover method provided by the present application. In the embodiment, the method is applied to a thin plate segmented turnover system composed of a carrying device, a transport trolley, and a turnover device, wherein the turnover device includes a turnover platform, a lifting device, and a turnover driving device, the lifting device includes two lifting beams arranged on both sides of the turnover platform, and the middle positions of each lifting beam are connected to the middle positions of the sides of the turnover platform through a rotating shaft, respectively, and the turnover platform can rotate relative to the lifting beams around the rotating shaft; the method includes the following steps:

[0085] S131: The transport trolley and the carrying device cooperate to place the thin plate segment to be turned over on the turnover platform.

[0086] S132: The lifting device lifts the lifting beam, and then lifts the turnover platform connected to the lifting beam through the rotating shaft and the thin plate segment to be turned over fixed on the turnover platform to a preset height.

[0087] S133: The turnover driving device drives the rotating shaft to rotate, so as to drive the turnover platform fixedly connected to the rotating shaft, the thin plate segment to be turned over fixed on the turnover platform, and the thin plate segment to be turned over to rotate relative to the lifting beam by a set angle, so as to realize the turnover of the thin plate segment to be turned over.

[0088] S134: The lifting device lowers the lifting beam, and then places the turnover platform after turnover and the thin plate segment after turnover fixed on the turnover platform on the transport trolley and separates the thin plate segment after turnover from the turnover platform, and transfers the thin plate segment after turnover to the next station by the transport trolley.

[0089] S135: The turnover device separated from the thin plate segment after turnover is reset by the cooperation of the lifting device and the turnover driving device.

[0090] The above-mentioned setting angle is an arbitrary angle, for example, 180 degrees. As an implementable manner, the lifting device further comprises four columns, the columns are provided with inclined pull rods on the sides, and each column is further provided with a lifting driving assembly. The lifting driving assembly can comprise a fixed pulley set, a movable pulley set, a steel wire rope and a lifting winch. The lifting beams can be provided with wear-resistant sliding blocks at both ends, and the sliding blocks slide in the columns. The upward pulling force of the lifting beam is provided by the lifting winch and is transmitted through the fixed pulley set and the movable pulley set. After being lifted to the highest position, the lifting winch brake is applied. The rotating shafts at both ends of the turning platform are installed in the lifting beams in cooperation with bearings, and the turning of the turning platform is realized by the extension or shortening of the two groups of hydraulic turning cylinders on both sides.

[0091] The thin plate segment turning system in the embodiment can be the thin plate segment turning system in the above-mentioned structural embodiment, and therefore the thin plate segment turning method of the embodiment can be understood in combination with the related structural schematic diagram and the related textual description. It can be understood that each step in the method flow in the embodiment can be adjusted and refined according to actual needs, for example, a corresponding flow step can be added according to the specific structure of the thin plate segment turning system, and the specific steps can be understood and supplemented in combination with the above-mentioned related structural schematic diagram and the textual description of the related structure. Here, the detailed description and explanation of each flow step are not repeated.

[0092] In this way, the thin plate segment turning system in the application adopts two lifting beams arranged at the middle positions of the two sides of the turning platform to be connected to the middle positions of the sides of the turning platform through a rotating shaft respectively, so that the turning platform can rotate relative to the lifting beams around the rotating shaft. Then, the turning platform and the thin plate segment fixed on the turning platform connected through the rotating shaft can be lifted to a preset height together with the lifting beams, and the turning platform is rotated 180 degrees around the rotating shaft relative to the lifting beams, so as to realize the turning of the thin plate segment. The turning operation of the thin plate segment is simple and convenient, and the turning process is safe. Moreover, since the middle positions of the two lifting beams are connected to the middle positions of the two sides of the turning platform through a rotating shaft respectively, the preset height to which the turning platform is lifted only needs to be not less than half of the width of the turning platform, and the occupied operation space is small, which is particularly suitable for indoor places such as workshops and warehouses.

[0093] The application provides a flow description of an embodiment of a method for rotating a thin plate segment 180 degrees by using a turning device in a thin plate segment turning method. Figure 14 , Figure 14is a flowchart of an embodiment of a method for rotating a sheet segment by 180 degrees using a turnover device in a turnover method of the sheet segment. In this embodiment, the method is applied to a turnover device composed of a turnover platform, a lifting device, and a turnover driving device. The lifting device includes two lifting beams arranged on both sides of the turnover platform. The middle positions of each lifting beam are connected to the middle positions of the sides of the turnover platform through a rotating shaft, respectively. The turnover platform can rotate relative to the lifting beams around the rotating shaft. The turnover driving device includes two rotating discs and four turnover cylinders. Each rotating disc is correspondingly sleeved on a rotating shaft and rotates coaxially with the rotating shaft. At least two connecting holes are arranged on each rotating disc. Two turnover cylinders are arranged on each lifting beam. One end of each turnover cylinder is fixedly connected to the lifting beam, and the other end is telescopically connected to a connecting hole on the corresponding rotating disc. The rotating disc and the turnover cylinder can rotate around the connecting hole. The installation positions of the four turnover cylinders are symmetric about the line connecting the two rotating shafts. The method includes the following steps:

[0094] S141: After the lifting device lifts the turnover platform and the sheet segment to be turned over fixed on the turnover platform to a preset height, the rotating disc is rotated by a set angle around the rotating shaft by the extension and contraction of the left turnover cylinder and the extension and contraction of the right turnover cylinder, thereby driving the turnover platform connected to the rotating shaft and the sheet segment to be turned over fixed on the turnover platform as a whole to rotate around the rotating shaft by a set angle.

[0095] It can be understood that the set angle can be any angle, and in this embodiment, it is 180 degrees. The extension and contraction of the left turnover cylinder and the extension and contraction of the right turnover cylinder can apply a torque to the rotating disc that can make the rotating disc rotate in the same direction around the rotating shaft, thereby rotating the rotating disc around the rotating shaft.

Since the turning-over platform can rotate relative to the lifting beam around the rotating shaft, the rotating disc rotates coaxially with the rotating shaft on which the rotating disc is sleeved, and the rotating disc and the turnover oil cylinder can rotate around the connecting hole. The extension and contraction of the turnover oil cylinder located on the left side and the extension and contraction of the turnover oil cylinder located on the right side are matched to make the rotating disc rotate 180 degrees around the rotating shaft, so that the turning-over platform connected with the rotating shaft and the sheet segments fixed on the turning-over platform can be driven to rotate 180 degrees around the rotating shaft as a whole, so that the turning-over process of the sheet segments of the application can control the turning-over speed of the turnover oil cylinder, prevent a large acceleration from affecting the stability of the equipment structure during the turning-over process, and make the turning-over process very safe. The turning-over platform and the lifting beam are cooperated with each other through the turnover oil cylinder, the rotating disc and the connecting shaft to provide the turning-over power for the turning-over platform during the turning-over and keep the balance during the non-turning-over.
