Specific implementation

[0029] The utility model will be further described below in conjunction with the embodiment shown in the drawings.

[0030] As Figures 1-4 It is the structure schematic view of the turnover machine of the utility model photovoltaic module packing tray, the turnover machine is used for overturning tray, and then the vertical packing of photovoltaic module (photovoltaic board) is facilitated, and the turnover machine includes bottom frame 1, turnover mechanism and clamping mechanism. Wherein bottom frame 1 is formed by welding the aluminum profile vertically and horizontally, mainly plays the role of support, and bottom frame 1 is fixed on the workshop packing ground by the bolt fastening mode. Turnover mechanism is installed at the top of bottom frame 1, and clamping mechanism is installed at one side of turnover mechanism, clamps tray through clamping mechanism, and then overturns tray under the action of turnover mechanism, to complete the vertical packing of photovoltaic module.

[0031] The turnover mechanism comprises a sliding frame 2, a motor mounting plate 3, a first motor 4, a gear 5, a rack 6, a turnover frame 7 and a turnover cylinder 8. The sliding frame 2 is made of aluminum profiles and is welded horizontally and longitudinally, and is movably mounted on the top of the bottom frame 1 and used for conveying the packaged tray. Specifically, the first slide rail is at least two, is fixed on the top of the bottom frame 1 by screw fastening, and the length direction of the first slide rail is parallel to the length direction of the bottom frame 1. The first slide block is slidably mounted on the first slide rail, and the sliding frame 2 is fixed on the top of the first slide block by screw fastening. When the driving unit drives the sliding frame 2 to move, the sliding frame 2 will drive the first slide block to move synchronously along the length direction of the first slide rail, so as to improve the stability of the movement of the sliding frame 2.

[0032] The driving unit comprises the motor mounting plate 3, the first motor 4, the gear 5 and the rack 6. The rack 6 is fixed on one side of the top of the bottom frame 1 by screw fastening, and the length direction of the rack 6 is parallel to the length direction of the bottom frame 1. The motor mounting plate 3 is fixed on the top of the sliding frame 2 by screw fastening, the motor shell of the first motor 4 is fixed on the bottom of the motor mounting plate 3 by screw fastening, the gear 5 is installed on the motor shaft of the first motor 4 by key connection, and the gear 5 is engaged with the rack 6. When the first motor 4 drives the gear 5 to rotate, the sliding frame 2 is driven to slide along the length direction of the rack 6 through the engagement of the gear 5 and the rack 6, so as to convey the packaged tray.

[0033] The turnover frame 7 is made of aluminum profiles and is rotatably mounted on one side of the top of the sliding frame 2. The cylinder body of the turnover cylinder 8 is rotatably connected with the top of the sliding frame 2, and the piston rod of the turnover cylinder 8 is rotatably connected with one side of the turnover frame 7. The turnover frame 7 is driven to turn by the turnover cylinder 8, so as to turn the tray clamped thereon (the turnover cylinder 8 can be a commercially available linear cylinder).

[0034] As shown in Figure 8 , the fixed plate 31 is fixed on one side of the sliding frame 2 by screw fastening, the first mounting plate 32 and the second mounting plate 33 are fixed on the side of the fixed plate 31 away from the sliding frame 2 by welding, and the first mounting plate 32 and the second mounting plate 33 are spaced apart to form an installation gap for installing the turnover cylinder 8. The adapter block 34 is fixed on one side of the cylinder body of the turnover cylinder 8 by welding and is arranged in the installation gap between the first mounting plate 32 and the second mounting plate 33.

[0035] The first shaft hole horizontally penetrates the first mounting plate 32, the second shaft hole horizontally penetrates the second mounting plate 33 and is coaxially arranged with the first shaft hole, and the mounting hole horizontally penetrates the adapter block 34 and is coaxially arranged with the first shaft hole. The pin shaft 35 penetrates the first shaft hole, the mounting hole and the second shaft hole in sequence, and the pin shaft 35 ensures that the cylinder body of the turnover cylinder 8 is in a rotary connection state with the sliding frame 2. (In order to avoid axial deviation of the pin shaft 35, annular clamping grooves are formed at both ends of the pin shaft 35, the axis of the clamping grooves is coaxially arranged with the rotary axis of the pin shaft 35, and the clamping spring is clamped in the clamping groove to axially limit the pin shaft 35).

[0036] The piston rod of the turnover cylinder 8 and the turnover frame 7, and the turnover frame 7 and the sliding frame 2 are also connected in rotation by the pin shaft 35 structure.

[0037] The clamping mechanism is installed on one side of the turnover frame 7, and the tray is clamped by the clamping mechanism, and then the tray is turned over under the action of the turnover mechanism. The clamping mechanism includes a feeding assembly and a clamping assembly. The feeding assembly is installed on the side of the turnover frame 7 away from the sliding frame 2, and is used for conveying the packaged tray. The clamping assembly is arranged on both sides of the feeding assembly, and is used for clamping the tray conveyed by the conveying assembly.

[0038] The feeding assembly includes a roller shaft mounting plate 20, a roller shaft 21, a second motor 22, a driving belt 23 and a synchronous belt 24. The roller shaft mounting plate 20 has two plates, which are fixed on the side of the turnover frame 7 away from the sliding frame 2 by welding. The two roller shaft mounting plates 20 are arranged in the vertical direction and are spaced apart, and are used for installing the roller shaft 21. The roller shaft 21 has a plurality of roller shafts, which are rotatably installed between the two roller shaft mounting plates 20. Specifically, through holes are formed in the corresponding positions of the two roller shaft mounting plates 20, and the two ends of the roller shaft 21 are respectively installed in the through holes of the roller shaft mounting plate 20 through bearings. Under the action of the bearings, the roller shaft 21 can rotate normally.

[0039] As shown in Figure 6 Each roller shaft 21 is axially sleeved with two synchronous wheels, the synchronous belt 24 is wound around the synchronous wheels of adjacent two roller shafts 21, and the synchronous belt 24 is staggered along the axis direction of the roller shaft 21. The housing of the second motor 22 is installed on one side of the turnover frame 7 by screw fastening, the driving wheel is installed on the motor shaft of the second motor 22 by key connection, and the driving belt 23 is wound around the driving wheel and the synchronous wheel of one of the roller shafts 21. The second motor 22 drives the driving belt 23 to rotate, and drives the roller shaft 21 to rotate under the action of friction, so as to convey the packaged tray.

[0040] The clamping mechanism includes a first push cylinder 9, a push plate 10, an extension plate 11, a groove 12, a reinforcing plate 13, a support frame 25, a guide sleeve 26, a guide column 27, a second push cylinder 28, a resistance plate 29 and a folding plate 30. As shown in Figure 4As shown, the pushing plate 10 is slidingly installed on the turnover frame 7 away from the sliding frame 2 (specifically, the second sliding rail is fixed on the side of the turnover frame 7 away from the sliding frame 2 by screw fastening, the second sliding block is slidingly installed on the second sliding rail, and the pushing plate 10 is fixed on the side of the second sliding block away from the second sliding rail by screw fastening. When the first pushing cylinder 9 drives the pushing plate 10 to move, the cooperation of the second sliding rail and the second sliding block improves the stability of the movement of the pushing plate 10).

[0041] The cylinder body of the first pushing cylinder 9 is rotatably connected to the turnover frame 7 by a pin shaft, and the piston rod of the first pushing cylinder 9 is rotatably connected to one side of the pushing plate 10 by a pin shaft. The first pushing cylinder 9 drives the pushing plate 10 to move, thereby satisfying the clamping of trays of different sizes and improving the versatility of the equipment (a commercially available linear cylinder can be selected for the first pushing cylinder 9). The two ends of the first pushing cylinder 9 are arranged in a hinged structure, which can compensate for installation errors. If a rigid fixation is adopted, a slight deviation in centering will cause the piston rod to bear a lateral force, accelerate the wear of the sealing element, and even cause jamming or air leakage.

[0042] The extension plate 11 is fixed on the side of the pushing plate 10 away from the turnover frame 7 by welding and passes through the gap between the adjacent roller shafts 21 without interfering with the tray on the roller shaft 21. Figure 7 As shown, the support frame 25 is fixed on the roller shaft mounting plate 20 by screw fastening and is arranged opposite to the extension plate 11. The guide sleeve 26 is embedded in the support frame 25, the guide column 27 is embedded in the guide sleeve 26, and the end of the guide column 27 close to the extension plate 11 is welded with the abutting plate 29. The movement of the abutting plate 29 is guided by the cooperatively arranged guide sleeve 26 and guide column 27 to avoid tilting of the abutting plate 29 during movement.

[0043] The cylinder body of the second pushing cylinder 28 is fixed on one side of the support frame 25 by screw fastening, the piston rod of the second pushing cylinder 28 passes through the support frame 25, and the piston rod is connected to the abutting plate 29 through a floating joint. The second pushing cylinder 28 drives the abutting plate 29 to move (a commercially available linear cylinder can be selected for the second pushing cylinder 28).

[0044] The folding plate 30 is integrally connected to the side of the abutting plate 29 away from the roller shaft 21 and is perpendicular to the abutting plate 29 (i.e., the abutting plate 29 and the folding plate 30 form an "L" shape). The operator places the tray on the roller shaft 21, the second pushing cylinder 28 drives the abutting plate 29 to move, and the tray is clamped between the abutting plate 29 and the extension plate 11, completing the clamping of the tray and avoiding damage to the tray caused by falling during subsequent turnover (since the abutting plate 29 and the folding plate 30 form an "L" shape, the angle plate structure formed by the folding plate 30 and the abutting plate 29 will be clamped on the side of the rectangular tray, thereby avoiding the tray from falling during turnover).

[0045] AsFigure 5 As shown, the groove 12 is formed at the bottom of the extension plate 11 to reduce the weight of the extension plate 11. The reinforcing plate 13 is fixed in the groove 12 by welding, and the included angle between two adjacent reinforcing plates 13 is 120° to improve the structural strength of the extension plate 11 and prevent the extension plate 11 from bending when supporting the photovoltaic panel.

[0046] Two limiting plates 14 are fixed to the groove 12 of the extension plate 11 by welding. A guide sleeve 15 is embedded in the limiting plate 14, and a guide post 16 passes through the guide sleeve 15. A buffer plate 17 is fixed to the end of the guide post 16 away from the extension plate 11. A connecting plate 19 is fixed to the end of the guide post 16 away from the buffer plate 17 to ensure the synchronous movement of the two guide posts 16 and to prevent the buffer plate 17 from falling out of the guide sleeve 15 when resetting. A spring 18 is sleeved on the guide post 16 and is located between the buffer plate 17 and the guide sleeve 15 (when the robotic arm grips the photovoltaic panel and places it on the extension plate 11, the buffer plate 17 on one side of the extension plate 11 prevents the photovoltaic panel from directly and rigidly contacting the side of the extension plate 11 and causing a collision).

[0047] The photovoltaic module packaging pallet flipping machine of this utility model first places the pallet on the roller 21 when packaging photovoltaic modules. Then, the second push cylinder 28 pushes the abutment plate 29 to move until the pallet is clamped between the abutment plate 29 and the extension plate 11, completing the pallet clamping. The flipping cylinder 8 then drives the flipping frame 7 to rotate... Figure 3 As shown, the first motor 4 drives the sliding frame 2 to move to the loading station (at this time, the pallet is in a vertical state). The robotic arm picks up the photovoltaic panels and places them horizontally on the extension plate 11 (at this time, the side of the photovoltaic panel is against the pallet). After placing a specified number of photovoltaic panels, the packing straps are tied to the outside of the photovoltaic panels. To prevent the photovoltaic panels from slipping as a whole, the pallet and photovoltaic panels can be tied together with another layer of packing straps around the perimeter. After the packing is completed, the flipping cylinder 8 drives the flipping frame 7 to flip. At the same time, the first motor 4 drives the sliding frame 2 to move out of the loading station (at this time, the pallet is in a horizontal state, and the photovoltaic panels are turned to a vertical state, thus completing the vertical installation of the photovoltaic panels). Finally, the rotating roller 21 removes the packed pallet.

They should not be construed as limiting the scope of protection of this utility model.
