Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, and in particular to a material lifting and turning device. Background Technology

[0002] Photovoltaic modules (also called solar panels) are power generation systems that convert solar energy into electrical energy. Their structure is generally a rectangular flat plate with dimensions no less than 1 meter in length and width. Due to their fragile nature, safe movement is a crucial consideration during the manufacturing process. Sometimes, electronic components need to be installed on both sides during manufacturing, which may necessitate flipping the modules during transportation.

[0003] Chinese patent CN110255137A discloses a flipping final inspection machine, which includes a lifting and conveying mechanism and a clamping and flipping assembly. The lifting and conveying mechanism includes a conveying assembly and a lifting assembly. The conveying assembly is used to translate the photovoltaic module within a lower horizontal conveying surface. The lifting assembly is used to raise the photovoltaic module to the flipping height of the clamping and flipping assembly and to lower the photovoltaic module to the horizontal conveying surface. The clamping and flipping assembly can flip the photovoltaic module 180° around a higher rotation axis. The clamping and flipping assembly includes a clamping component that can clamp the wide side of the photovoltaic module from both sides in the horizontal conveying direction, and then flip it using the flipping assembly. However, there is a drawback: photovoltaic modules vary in width, and when the clamping assembly clamps the photovoltaic module, the axis of symmetry of the photovoltaic module in the front-to-back direction may not be collinear with the rotation axis. If, during the flipping process, the downward flipped portion of the photovoltaic module is wide, and this width is greater than the height difference between the rotation axis and the horizontal conveying surface, the photovoltaic module may collide with the conveying assembly, thus posing a risk of damage.

[0004] Therefore, it is necessary to improve the structure of the flip component to solve the above problems. Utility Model Content

[0005] The main purpose of this invention is to provide a material lifting and turning device that can center the conveying direction in the front and back when clamping, so as to prevent the downward turning part of the photovoltaic module from hitting the lifting conveyor line and ensure the safety of product conveying.

[0006] This utility model achieves the above objective through the following technical solution: a material lifting and turning device, comprising:

[0007] frame;

[0008] A pair of flipping assemblies are respectively located on the left and right sides of the upper part of the frame. Each flipping assembly includes a flipping drive, a flipping beam, a translation drive assembly, and a pair of flipping arms. The rotation axes of the two flipping drives are collinear and are along the left-right direction. The middle part of the flipping beam is connected to the drive shaft of the flipping drive and the length direction of the flipping beam is perpendicular to the rotation axis. The translation drive assembly drives the two flipping arms to translate along the length direction of the flipping beam. The mirror surfaces of the two flipping arms always pass through the rotation axis. The two flipping arms on the same flipping assembly clamp the photovoltaic module from the front and rear sides. A first linear guide rail is provided on the flipping beam along its length direction. The flipping arm is L-shaped and includes a sliding part and a clamping part connected vertically. The sliding part moves along the first linear guide rail.

[0009] A lifting assembly line is located at the lower part of the frame. The lifting assembly line includes a synchronous lifter fixed to the lower part of the frame and a synchronous conveyor line driven by the synchronous lifter to lift. The synchronous conveyor line conveys photovoltaic modules in the front-to-back direction. The tilting arm is located outside the left and right sides of the lifting range of the synchronous conveyor line. The maximum clamping width of the tilting arm is less than 2H, where H is the height difference between the rotating shaft and the conveying surface of the synchronous conveyor line.

[0010] Specifically, the frame includes a fence and two flip support frames located on the left and right sides of the fence. The upper part of the flip support frame is higher than the highest point of the fence, and the two flip components are respectively fixed to the upper part of the two flip support frames. The lifting assembly line, the front and rear centering assembly and the left and right centering assembly are all located within the area enclosed by the fence and are staggered from each other.

[0011] Specifically, the synchronous lifter includes four push rods arranged in a rectangle below the synchronous conveyor line and a power coupling that drives the four push rods to lift synchronously.

[0012] Specifically, the flipping assembly further includes a flipping base for connecting the flipping drive to the frame. The flipping base includes a base plate, a vertical plate disposed on the base plate, and two reinforcing plates disposed in the inner angle formed by the base plate and the vertical plate. The flipping drive is fixed to the vertical plate and located between the two reinforcing plates. The drive shaft of the flipping drive passes through the vertical plate and is connected by a bearing.

[0013] Specifically, the clamping part has two flexible clamping blocks in the groove.

[0014] Specifically, the translation drive assembly includes a motor fixed to the middle of the tilting beam, a coupling screw extending from both ends of the motor, and two threaded sleeves that are threaded to both ends of the coupling screw. The axis of the coupling screw is parallel to the length direction of the tilting beam, and the threads at both ends rotate in opposite directions. Each threaded sleeve is connected to a sliding part. The tilting beam is provided with two pairs of screw seats. Each pair of screw seats is passed through by the same end of the coupling screw and connected by a bearing. The threaded sleeve moves between the two screw seats.

[0015] Specifically, one of the flipping arms is equipped with a gripping sensor at its end to detect the proximity of the photovoltaic module.

[0016] Specifically, it also includes a front and rear centering component, which includes a second linear guide rail, a front and rear centering drive mechanism, two front and rear sliders, two pairs of lifting drive components, and two pairs of front and rear limit stop wheels. The length direction of the second linear guide rail is along the front and rear direction. The front and rear sliders are respectively located in the front and rear direction of the lifting conveyor and slide along the second linear guide rail. Each front and rear slider is provided with two lifting drive components. Each lifting drive component drives one front and rear limit stop wheel to rise and fall. The two front and rear limit stop wheels on the same front and rear slider are arranged side by side. The front and rear centering drive mechanism drives the two front and rear sliders to move synchronously in opposite directions.

[0017] Furthermore, it also includes a left-right centering component, which includes a left-right centering drive mechanism, two third linear guides, two left and right sliders, and two pairs of left and right limiting wheels. The two third linear guides are respectively located on the left and right sides of the second linear guide, and their length direction is along the left and right direction. The left and right sliders are respectively located in the left and right directions of the lifting conveyor line and each slides along a third linear guide. Each left and right slider is provided with two left and right limiting wheels, and the two left and right limiting wheels on the same left and right slider are arranged one after the other. The left-right centering drive mechanism drives the two left and right sliders to move synchronously in opposite directions.

[0018] The beneficial effects of this utility model's technical solution are:

[0019] After the photovoltaic module is clamped by the flipping arm, the photovoltaic module rotates along its axis of symmetry parallel to its long side. During the flipping process, the height difference between the lowest position of the photovoltaic module and the rotating shaft is half the width of the photovoltaic module (i.e., the clamping width of the flipping arm). The drop between the rotating shaft and the conveying surface of the synchronous conveyor line is H. As long as this drop allows the lowest point of the photovoltaic module to pass through, it will not collide with the photovoltaic module. Therefore, as long as the maximum clamping width of the flipping arm is less than 2H, the flipping safety can be guaranteed. Attached Figure Description

[0034] 200 - Photovoltaic modules. Detailed Implementation

[0035] The present invention will be further described in detail below with reference to specific embodiments.

[0036] Example:

[0037] like Figure 1 , Figure 6 and Figure 7 As shown, the present invention provides a material lifting and turning device 100, which includes a frame 1, a pair of turning components 2, a lifting conveyor line 3, a front and rear centering component 4, and a left and right centering component 5. The pair of turning components 2 are respectively located on the left and right sides of the upper part of the frame 1, and the lifting conveyor line 3, the front and rear centering component 4, and the left and right centering component 5 are located at the lower part of the frame 1.

[0038] The frame 1 serves as the fixed foundation for the flipping assembly 2, the lifting conveyor line 3, the front-to-back centering assembly 4, and the left-to-right centering assembly 5, and has a skeletal structure. The flipping assembly 2 is used to flip the photovoltaic module 200 back and forth. The lifting conveyor line 3 is used to move the photovoltaic module 200 into and out of the equipment in the front-to-back direction, and to achieve vertical lifting and lowering of the photovoltaic module 200. The front-to-back centering assembly 4 determines the front-to-back position of the photovoltaic module 200 after it enters the equipment, and the left-to-right centering assembly 5 determines the left-to-right position of the photovoltaic module 200 after it enters the equipment.

[0039] like Figure 1 As shown, the frame 1 includes a fence 11 and two tilting support frames 12 located on the left and right sides of the fence 11. The upper part of the tilting support frame 12 is higher than the highest point of the fence 11, and two tilting components 2 are respectively fixed to the upper parts of the two tilting support frames 12. The lifting conveyor line 3, the front-to-back centering component 4, and the left-to-right centering component 5 are all located within the area enclosed by the fence 11 and are staggered from each other. The front-to-back direction is the conveying direction of the lifting conveyor line 3, and the left-to-right direction is the direction perpendicular to the conveying direction in the horizontal plane.

[0040] The flipping component 2 needs to be positioned at a higher level, so it should be located on the upper part of the frame 1 and fixed to the flipping support frame 12. The fence 11 serves to support and protect the components of the lifting assembly line 3, the front and rear centering components 4, and the left and right centering components 5.

[0041] like Figures 2 to 4 As shown, each flip assembly 2 includes a flip base 21, a flip drive 22, a flip beam 23, a translation drive assembly 24, and a pair of flip arms 25. The two flip drive 22s have collinear axes of rotation along the left-right direction. The middle part of the flip beam 23 is connected to the drive shaft of the flip drive 22, and the length direction of the flip beam 23 is perpendicular to the axis of rotation. The two flip arms 25 are L-shaped and mirror-symmetrically arranged at both ends of the flip beam 23. The translation drive assembly 24 drives the two flip arms 25 to translate along the length direction of the flip beam 23. The mirror-like surfaces of the two flip arms 25 always pass through the axis of rotation. The two flip arms 25 on the same flip assembly 2 clamp the photovoltaic module 200 from the front and rear sides. One flip arm 25 has a gripping sensor 26 at its end to sense the proximity of the photovoltaic module 200.

[0042] The flip base 21 connects the flip drive 22 to the frame 1. The flip drive 22 is a servo motor or a rotary motor. The flip beam 23 fixes the translation drive assembly 24 and the flip arm 25, and rotates or turns under the control of the flip drive 22. The flip arms 25 clamp the long edge of the photovoltaic module 200 by moving closer to each other. The translation drive assembly 24 is used to achieve symmetrical movement of the two flip arms 25 towards and away from each other on a defined mirror plane (perpendicular to the length direction of the flip beam 23). Because the flip arms 25 move in a centered manner, after the flip arms 25 clamp the photovoltaic module 200, the line of symmetry of the photovoltaic module 200 must be at the height of the rotation axis. The clamp sensor 26 is used to detect whether the photovoltaic module 200 has reached the appropriate height, so as to ensure that the photovoltaic module 200 can be clamped when the flip arms 25 move closer to each other.

[0043] like Figure 2 As shown, the flipping base 21 includes a base plate 211 connected to the flipping support frame 12, a vertical plate 212 vertically arranged on the base plate 211, and two reinforcing plates 213 arranged in the inner angle formed by the base plate 211 and the vertical plate 212. The flipping drive member 22 is fixed on the vertical plate 212 and located between the two reinforcing plates 213. The drive shaft of the flipping drive member 22 passes through the vertical plate 212 and is connected by a bearing.

[0044] Half the weight of the photovoltaic module 200 is carried on the drive shaft of the flipping drive 22, and the direction of the load is always perpendicular to the axis of the drive shaft. To prevent wear on the drive shaft during operation, a flipping seat 21 is specially designed to distribute the load on the drive shaft. The bearing can guide the load to the upright plate 212 while protecting the smooth rotation of the drive shaft, and then transfer it to the flipping support frame 12 through the base plate 211. The two reinforcing plates 213 can stabilize the angle between the upright plate 212 and the base plate 212, thereby protecting the flipping drive 22.

[0045] like Figure 4 As shown, a first linear guide rail 231 is provided on the flip beam 23 along its length direction. The flip arm 25 includes a sliding part 251 and a clamping part 252 connected vertically. The sliding part 251 moves along the first linear guide rail 231. The clamping part 252 has a groove-shaped cross section with the groove opening facing the clamping part 252 on the other side. Two flexible clamping blocks 253 are provided in the groove of the clamping part 252.

[0046] The first linear guide rail 231 enables the flipping arm 25 to move accurately along the length of the flipping beam 23. The first linear guide rail 231 can distribute the load of the flipping arm 25, preventing it from deviating from its direction of movement. The clamping part 252 contacts the photovoltaic module 200 not only on the side but also on both sides of the photovoltaic module 200 to prevent it from falling during flipping. The flexible clamping block 253 on the inner side of the clamping part 252 contacts the photovoltaic module 200, ensuring flexible contact between the flipping arm 25 and the edge of the photovoltaic module 200, preventing damage or breakage. The two flexible clamping blocks 253 on each flipping arm 25 provide relatively stable clamping.

[0047] like Figure 2 and Figure 4 As shown, the translation drive assembly 24 includes a motor 241 fixed to the middle of the tilting beam 23, a coupling screw 242 extending from both ends of the motor 241, and two threaded sleeves 243 respectively threaded to both ends of the coupling screw 242. The axis of the coupling screw 242 is parallel to the length direction of the tilting beam 23 and the threads at both ends rotate in opposite directions. Each threaded sleeve 243 is connected to a sliding part 251. The tilting beam 23 is provided with two pairs of screw seats 232. Each pair of screw seats 232 is passed through by the same end of the coupling screw 242 and connected by a bearing. The threaded sleeves 243 move between the two screw seats 232.

[0048] Both ends of the coupling screw 242 are driven by motors 241, maintaining a consistent rotation speed. To ensure synchronized and opposite movements of the two tilting arms 25 on the same tilting assembly 2, the two threaded sleeves 243 have the same pitch but rotate in opposite directions. This translation drive assembly 24 has a self-locking function; when the drive shaft of the motor 241 is not rotating, the tilting arms 25 will not move away on their own, preventing the photovoltaic module 200 from being loosened and falling. Because the coupling screw 242 is a precision component and susceptible to deformation, the bearings here are designed to reduce axial misalignment that could cause jamming.

[0049] like Figure 5 As shown, the lifting assembly line 3 includes a synchronous lifter 31 fixed to the lower part of the frame 1 and a synchronous conveyor line 32 driven by the synchronous lifter 31 to lift and lower. The synchronous lifter 31 includes four push rods 311 arranged in a rectangle at the lower part of the synchronous conveyor line 32 and a power coupling 312 that drives the four push rods 311 to lift and lower synchronously. The synchronous conveyor line 32 conveys photovoltaic modules 200 in the front-to-back direction. The tilting arms 25 are located outside the left and right sides of the lifting range of the synchronous conveyor line 32. The maximum clamping width of the tilting arms 25 is less than 2H, where H is the height difference between the rotating shaft and the conveying surface of the synchronous conveyor line 32.

[0050] The synchronous lifter 31 ensures that the photovoltaic module 200 is lifted smoothly. During transfer, the photovoltaic module 200 must be raised to the height of the tilting arm 25, and the lowest point of the tilting arm 25 must be below the lower surface of the photovoltaic module 200. The synchronous conveyor line 32 will also contact the lower surface of the photovoltaic module 200 when lifting it. The tilting arm 25 moves along the front-to-back direction, while the photovoltaic module 200 moves along the up-down direction. Regardless of the length of the photovoltaic module 200, the tilting arm 25 must ensure that it is not hit by the synchronous conveyor line 32, especially the end of the clamping part 252. Therefore, the tilting arm 25 must be outside the lifting range of the synchronous conveyor line 32. After the flipping arm 25 clamps the photovoltaic module 200, the photovoltaic module 200 rotates along its axis of symmetry parallel to its long side. During the flipping process, the height difference between the lowest position of the photovoltaic module 200 and the rotating shaft is half the width of the photovoltaic module 200 (that is, the clamping width of the flipping arm 25). The drop between the rotating shaft and the conveying surface of the synchronous conveying line 32 is H. As long as this drop allows the lowest point of the photovoltaic module 200 to pass through, it will not collide with the photovoltaic module 200. Therefore, as long as the maximum clamping width of the flipping arm 25 is less than 2H, the flipping safety can be guaranteed.

[0051] like Figure 5 As shown, the front-to-back centering assembly 4 includes a second linear guide rail 41, a front-to-back centering drive mechanism 45, two front and rear sliders 42, two pairs of lifting drive components 43, and two pairs of front and rear limiting stop wheels 44. The length direction of the second linear guide rail 41 is along the front-to-back direction. The front and rear sliders 42 are located in the front-to-back direction of the lifting conveyor line 3 and slide along the second linear guide rail 41. Each front and rear slider 42 is provided with two lifting drive components 43. Each lifting drive component 43 drives one front and rear limiting stop wheel 44 to rise and fall. The two front and rear limiting stop wheels 44 on the same front and rear slider 42 are arranged side by side. The front-to-back centering drive mechanism 45 drives the two front and rear sliders 42 to move synchronously in opposite directions. The left-to-right centering assembly 5 includes a left-to-right centering drive mechanism 54, two third linear guide rails 51, two left and right sliders 52, and two pairs of left and right limiting stop wheels 53. Two third linear guides 51 are respectively located on the left and right sides of the second linear guide 41, and their length direction is along the left and right direction. The left and right sliders 52 are located in the left and right directions of the lifting conveyor line 3 and slide along one of the third linear guides 51. Each left and right slider 52 is provided with two left and right limit wheels 53, and the two left and right limit wheels 53 on the same left and right slider 52 are arranged one after the other. The left and right centering drive mechanism 54 drives the two left and right sliders 52 to move synchronously in opposite directions.

[0052] Both the front-to-back centering drive mechanism 45 and the left-to-right centering drive mechanism 54 can adopt synchronous belt pulley mechanisms. The slider can be fixed to the two taut parts of the synchronous belt to achieve symmetrical movement of the slider. The front-to-back limit rollers 44 push the long side of the photovoltaic module 200 to center in the front-to-back direction, and the left-to-right limit rollers 53 push the short side of the photovoltaic module 200 to center in the left-to-right direction. In this way, the center position of the photovoltaic module 200 is always determined. This center position is below the axis of the flipping drive component 22 and is located on the mirror symmetry plane of the two flipping components 2. This ensures that there is an optimal initial distance between the photovoltaic module 200 and the flipping arm 25, avoiding accidental collisions. Since the front-to-back direction is the conveying direction of the synchronous conveyor line 32, the front-to-back limit rollers 44 cannot obstruct the movement of the photovoltaic module 200 when it moves back and forth. Therefore, the lifting drive component 43 needs to be hidden below the horizontal conveying surface. The left-to-right limit rollers 53 do not obstruct the movement of the photovoltaic module 200, so the lifting drive component is not required.

[0053] The working process of this material lifting and turning device 100 is as follows:

[0054] 1. The synchronous conveyor line 32 is initially in a low position and is connected to other production lines. With the front and rear limit rollers 44 descending, the synchronous conveyor line 32 moves the photovoltaic module 200 to its middle position.

[0055] 2. The front and rear limit stop wheels 44 are raised under the control of the lifting drive component 43. The front and rear centering components 4 and the left and right centering components 5 work together to act on the four sides of the photovoltaic module 200 to center the photovoltaic module 200. Then the front and rear centering components 4 and the left and right centering components 5 return to their positions.

[0056] 3. The flip beam 23 is initially in a horizontal position, the flip arms 25 are far apart, the synchronous lift 31 drives the synchronous conveyor line 32 to rise, and the photovoltaic module 200 also rises together. When the photovoltaic module 200 is sensed by the clamping sensor 26, the flip arms 25 move closer to each other and use the flexible clamping block 253 to clamp the two long sides of the photovoltaic module 200.

[0057] 4. The synchronous conveyor line 32 detaches from the lower surface of the photovoltaic module 200 and descends to the bottom. The flipping drive 22 drives the flipping beam 23 to rotate 180°, causing the photovoltaic module 200 to flip over. Then the synchronous conveyor line 32 rises again to support the photovoltaic module 200.

[0058] 5. The flip arm 25 releases the photovoltaic module 200, and the synchronous conveyor line 32 carries the photovoltaic module 200 back to the lowest conveyor surface, and then sends the photovoltaic module 200 out of the equipment forward or backward.

[0059] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
