Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic module production technology, and in particular relates to a plate placement device. Background Technology

[0002] Packaging photovoltaic (PV) modules requires pallets. First, spacers are placed on the pallet, then the PV modules are placed on the spacers, and so on, stacking the PV modules and spacers in sequence. Spacers are needed between the pallets and PV modules, and between every two layers of PV modules, to prevent friction and scratches between the modules. After stacking a set number of PV modules, the stack is then strapped and packaged to form a package of PV modules. Therefore, each package of PV modules requires a pallet, and the pallet should be placed face up when loading. However, when receiving PV modules, some are face up and some are face down. Manually flipping them is labor-intensive and inefficient. There is an urgent need to design a pallet loading mechanism that can simultaneously flip the pallets. The patent application number 2025210984570 filed earlier describes a board flipping unit, flipping mechanism, and feeding device that can achieve the flipping action of the pallet. However, after placing a partition paper on the pallet, the pallet and the partition paper are directly transported to the material cart. Because the partition paper is very thin and light, the partition paper and the pallet will shift during the process of moving the pallet and the partition paper together.

[0003] Therefore, in order to solve the above problems, it is urgent to design a device. The device should first identify the front and back of the pallet. If the back is identified, the pallet should be flipped over. Then, the spacer paper should be placed on the front of the pallet and then the spacer paper should be attached to the pallet. Then, the whole thing should be moved away for the subsequent stacking of photovoltaic modules. Therefore, it can realize both the flipping of the pallet and the attachment of the pallet and the spacer paper.

[0004] In the prior art, the pallet fastening device announced in Chinese Patent Publication No. CN203509528U includes a platform, a plate supply fastening unit, and a pallet flipping unit. The platform sequentially includes a pallet reverse fastening area and a pallet front fastening area along a first direction. The pallet flipping unit is located between the pallet reverse and front fastening areas. Although this solution includes a pallet flipping unit, a pallet reverse fastening area, and a pallet front fastening area, it first fastens corner strips to the front of the pallet, then flips the pallet over and fastens the corner strips to the reverse side, completing the fastening of the corner strips on both sides. Therefore, this solution cannot complete the aforementioned actions.

[0005] Therefore, it is necessary to provide a sheet material placement device to solve the above-mentioned technical problems. Utility Model Content

[0043] In this embodiment, the first feeding unit 3, the board flipping mechanism 1, the second feeding unit 4, the binding mechanism 2, and the receiving unit 5 are arranged sequentially from left to right in a straight line. Several conveying mechanisms include a first conveying mechanism 6 that conveys the first feeding unit 3 to the board flipping mechanism 1, a second conveying mechanism 7 that conveys the board 200 on the board flipping mechanism 1 to the binding mechanism 2 or the paper divider on the second feeding unit 4 to the binding mechanism 2, and a third conveying mechanism 8 that conveys the bound material on the binding mechanism 2 to the receiving unit 5. The first conveying mechanism 6, the second conveying mechanism 7, and the third conveying mechanism 8 are all jointly mounted on the gantry 9 via the XZ axis drive module 10.

[0044] In other embodiments, the layout of the first feeding unit 3, the board flipping mechanism 1, the second feeding unit 4, the binding mechanism 2, and the receiving unit 5 can be arranged according to the actual situation, and is not limited here; correspondingly, the number and layout of the handling mechanism are also changed accordingly, and are not limited here.

[0045] The board flipping mechanism 1 includes a first base 11, a first board flipping unit 12 and a second board flipping unit 13 disposed at the front and rear ends of the first base 11.

[0046] Both the first board flipping unit 12 and the second board flipping unit 13 include a mounting frame 14, a flipping drive module 15 mounted on the mounting frame 14, and a load-bearing clamping module 16 that is driven by the flipping drive module 15 to rotate around a horizontal axis.

[0047] The bearing clamping module 16 includes a rotating frame 161, a pair of clamping components 162 disposed at the left and right ends of the rotating frame 161 and clamping the left and right sides of the plate 200, and a straightening component 163 disposed on the rotating frame 161 and straightening the plate 200. The rotating frame 161 is provided with a limiting plate 164 for limiting the side of the plate 200. The clamping components 162 can clamp the upper and lower surfaces of the plate 200 on both sides to ensure the stability of the plate 200 during rotation. In addition, the straightening component 163 is provided to straighten the side of the plate 200, which can prevent the plate 200 from shifting position when loading.

[0048] A rotating shaft 165 is disposed in the middle of the rotating frame 161, and the rotating shaft 165 is rotatably mounted on the mounting frame 14 via a bearing 167. A support shaft 166 is disposed on one side of the rotating frame 161 with the rotating shaft 165. The flipping drive module 15 includes a first drive assembly 151 and a second drive assembly 152 that drive alternately. The first drive assembly 151 and the second drive assembly 152 are inclined and angled. The upper ends of the first drive assembly 151 and the second drive assembly 152 are rotatably mounted on the support shaft 166, and the lower ends are hinged to the mounting frame 14. The second drive assembly 152 is used to change the plate 200 from a horizontal state to a vertical state, and the first drive assembly 151 is used to change the plate 200 from a vertical state to a horizontal state. The first drive assembly 151 and the second drive assembly 152 operate alternately to realize the flipping action of the plate.

[0049] The first drive assembly 151 includes a first cylinder 1511 and a first drive rod 1512 extended by the first cylinder 1511. The second drive assembly 152 includes a second cylinder 1521 and a second drive rod 1522 extended by the second cylinder 1521. The top ends of the first drive rod 1512 and the second drive rod 1522 are rotatably mounted on the support shaft 166, and the length of the first drive rod 1512 is less than the length of the second drive rod 1522. The lower ends of the first cylinder 1511 and the second cylinder 1521 are hinged to the mounting bracket 14. Both the first cylinder 1511 and the second cylinder 1521 are equipped with an induction check valve 153, which ensures that the rotating frame 161 will rotate due to inertia when the first cylinder 1511 and the second cylinder 1521 are exhaling, making the rotation of the rotating frame 161 more stable and preventing the rotating frame 161 from swaying left and right when the first cylinder 1511 and the second cylinder 1521 are exhaling.

[0050] In this embodiment, the support shaft 166 is located to the left of the rotation shaft 165. Correspondingly, the first drive assembly 151 is located on the left, and the second drive assembly 152 is located on the right. The second cylinder 1521 of the second drive assembly 152 drives the second drive rod 1522 to retract, causing the rotating frame 161 to rotate 90° clockwise around the horizontal axis, changing the plate from a horizontal to a vertical state. Then, the first cylinder 1511 of the first drive assembly 151 drives the first drive rod 1512 to extend, causing the rotating frame 161 to continue rotating 90° clockwise around the horizontal axis, changing the plate from a vertical to a horizontal state, thus completing the plate flipping action. That is, the flipping drive module 15 drives the rotating frame 161 to rotate 180° clockwise around the horizontal axis to complete the plate flipping action.

[0051] In other embodiments, the support shaft 166 can be positioned to the right of the rotation shaft 165. Correspondingly, the first drive assembly 151 is positioned on the right, and the second drive assembly 152 is positioned on the left, with the rotation direction opposite to that described above. That is, the flipping drive module 15 drives the rotating frame 161 to rotate 180° counterclockwise around the horizontal axis to complete the flipping action of the sheet material. Therefore, the positions of the support shaft 166, the first drive assembly 151, and the second drive assembly 152 are set according to the actual situation and are not limited here.

[0052] The clamping assembly 162 includes a first clamping block 1621 clamping the upper surface of the board, a second clamping block 1622 clamping the lower surface of the board, a first clamping drive 1623 driving the first clamping block 1621 to extend and retract horizontally, and a second clamping drive 1624 driving the second clamping block 1622 to extend and retract horizontally. A limiting block 1625 is provided between the first clamping block 1621 and the second clamping block 1622 to limit the side edge of the board. The thickness of the limiting block 1625 is set to conform to the thickness of the board, which includes the sum of the thickness of the pallet and the thickness of the paper separator.

[0053] The correction component 163 includes a first correction component 163a for correcting the short side of the board and a second correction component 163b for correcting the long side of the board. Both the first correction component 163a and the second correction component 163b include a correction plate and a correction drive component for driving the correction plate closer to or further away from the side of the board.

[0054] The second board flipping unit 13 is movably mounted at one end of the first base 11 via a translation drive module 18. Boards are placed on the first board flipping unit 12 and the second board flipping unit 13. The translation drive module 18 drives the second board flipping unit 13 closer to the first board flipping unit 12, so that the first board flipping unit 12 and the second board flipping unit 13 together clamp the board for subsequent flipping. Furthermore, the translation drive module 18 allows the second board flipping unit 13 to move back and forth, adapting to boards of different lengths and improving the versatility of the board flipping mechanism 1. In this embodiment, the translation drive module 18 includes a second motor 181 mounted on the mounting frame 14, a second gear mounted on the output shaft of the second motor 181, a second rack meshing with the second gear at one end of the first base 11, and several slide rails at one end of the first base 11. The bottom of the mounting frame 14 is slidably mounted on the slide rails via a slider (not shown in the figure). In other embodiments, the translation drive module 18 may be configured as a motor-driven belt drive structure, thereby driving the second sheet metal flipping unit 13 to move back and forth. The structure of the translation drive module 18 is not limited here.

The Y-axis drive motor 2233 is mounted on a support frame 21, and the first movable frame 2232 is slidably mounted on the support frame 21 via a slider rail. The Y-axis drive motor 2233 drives the first movable frame 2232 to move the first alignment plate 2231 back and forth, which can adapt to boards 200 of the same length and improve the versatility of the binding device 100. That is, in this embodiment, the rear alignment module 224 is fixedly set, and the front alignment module 223 is movable back and forth, which can adapt to boards 200 of different lengths.

[0060] Binding modules 23 are provided on both the front and rear sides of the binding area 211. In this embodiment, the binding module 23 located on the front side of the binding area 211 is driven by the XY axis drive module 24 to move in the XY direction, and the binding module 23 located on the rear side of the binding area 211 is driven by the first X-axis drive component 25 to move in the X direction. The XY axis drive module 24 and the first X-axis drive component 25 are both mounted on the support frame 21.

[0061] The XY axis drive module 24 includes a Y axis drive assembly 241, a moving beam 242 driven by the Y axis drive assembly 241 to move in the Y direction, and a second X axis drive component 243 disposed on the moving beam 242. The binding module 23 on the front side of the binding area 211 is connected to the second X axis drive component 243. The left and right sides of the moving beam 242 are movably disposed on the support frame 21 by means of sliders and slide rails.

[0062] In this embodiment, the first X-axis drive unit 25 and the second X-axis drive unit 243 are both linear drive modules, or they can be servo motors driving linear movement. Their specific structures are not limited.

[0063] The second X-axis drive unit 243 and the first X-axis drive unit 25 enable the binding module 23 to move between the left and right sides of the board 200, so as to complete the binding of the left and right sides of the board 200, and also enable the binding operation of boards 200 of different widths; the Y-axis drive assembly 241 enables the binding module 23 at the front of the binding area 211 to move back and forth, and enables the binding operation of boards 200 of different lengths.

[0064] The binding module 23 includes a first support plate 234, a Z-axis drive 231 disposed on the first support plate 234, a mounting frame 232 driven by the Z-axis drive 231 to move along the Z-axis, and a nail gun 233 disposed on the mounting frame 232.

[0065] Nail gun 233 is existing technology, and its specific structure is not limited. It can adopt the design of existing technology. It can refer to the structure of the automatic nail gun in the 1013 automatic nail gun and automatic nailing device disclosed in Chinese Patent Publication No. CN118849120A, or the structure of the nail gun in the nail gun of the convenient nailing nail gun disclosed in Chinese Patent Authorization Announcement No. CN205904960U.

[0066] The first feeding unit 3, the second feeding unit 4, and the receiving unit 5 have the same or similar structures, each with three-sided enclosures forming a space for storing stacked materials. The first feeding unit 3 contains stacked boards, and the second feeding unit 4 contains stacked partition paper. A material-pulling trolley 20 is placed at the enclosure of the receiving unit 5. The pallets with the partition paper attached are transported onto the material-pulling trolley 20 for subsequent stacking of photovoltaic modules. In this embodiment, two first feeding units 3, two second feeding units 4, and two receiving units 5 are arranged side-by-side. The length and width dimensions of the enclosure spaces of the two first feeding units 3 can be the same or different, depending on the actual situation. If the length and width dimensions of the two enclosure spaces are the same, dual-station feeding can be achieved, improving feeding efficiency. If the length and width dimensions of the two enclosure spaces are different, feeding pallets of different sizes can be achieved, improving the versatility of the feeding mechanism. Since the dimensions of the paper divider correspond one-to-one with the dimensions of the pallet, the enclosure spaces of the second feeding unit 4 and the receiving unit 5 correspond to the enclosure spaces of the first feeding unit 3. In other embodiments, the first feeding unit 3, the second feeding unit 4, and the receiving unit 5 may also be one, three, or other quantities, depending on the actual space size, and are not limited here.

[0067] The first conveying mechanism 6 includes a first conveying frame 61, on which a first proximity switch 62 for sensing the plate is mounted, a first suction element 63 for adsorbing the plate, and a first camera (not shown) for photographing the plate. The first suction element 63 is preferably a sponge suction cup, which can stably adsorb the plate and avoid the risk of the plate falling. Other suction elements can also be used. The first camera (not shown) photographs the upper surface of the plate and transmits the photographed structure to the vision system. If the front side of the plate is detected to be facing up, a signal is given so that the plate flipping mechanism 1 does not need to flip the plate. If the back side of the plate is detected to be facing up, a signal is given so that the plate flipping mechanism 1 flips the plate.

[0068] The second transport mechanism 7 includes a second transport frame 71, on which a second proximity switch 72 for sensing the plate or paper separator is mounted, a second suction member 73 for adsorbing the paper separator, and a first clamping module 74 for clamping the plate. The second suction member 73 and the first clamping module 74 can be used selectively; that is, when transporting the paper separator, the second suction member 73 is used, preferably several suction cups, but other suction members are also acceptable. When transporting the plate, the first clamping module 74 is used to ensure the stability of the plate transport.

[0069] The third conveying mechanism 8 includes a third conveying frame 81, on which a third proximity switch 82 for sensing materials and a second clamping module 83 for clamping plates are provided.

Both the first clamping module 74 and the second clamping module 83 include a pair of left clamping plates and a right clamping plate, with two left clamping plates and two right clamping plates arranged opposite each other. In other embodiments, the number of left clamping plates and right clamping plates can be increased to improve clamping stability.

[0071] In this embodiment, in order to achieve the clamping action, the left or right clamping plate is extended or retracted by the clamping drive assembly 84. The clamping drive assembly 84 includes a clamping cylinder 841 and a push rod 842 disposed at the end of the clamped cylinder 841. The push rod 842 pushes the left or right clamping plate to extend or retract.

[0072] In other embodiments, both the left and right clamping plates are extended or retracted by the clamping drive assembly 84.

[0073] When using the board placement device 100 provided in this solution, the board 200 is first placed on the first feeding unit 3, the partition paper is placed on the second feeding unit 4, and the pulling trolley 20 is placed on the receiving unit 5. The first conveying mechanism 6 moves to the first feeding unit 3, the first camera takes a picture of the board 200 to identify the front and back of the board, the XZ axis drive module 10 drives the first conveying frame 61 to descend, and when the first proximity switch 62 contacts the board 200, the first suction member 63 descends to suction the board and transports the board to the board flipping mechanism 1. If the back of the board is facing up, the board flipping mechanism 1 flips the board so that the front of the board is facing up; if the front of the board 200 is facing up, there is no need to flip the board. The first clamping module 74 of the second conveying mechanism 7 directly transports the board with the front facing up to the binding mechanism 2, and then the second suction member 73 of the second conveying mechanism 7... The spacers are stacked on the surface of the board. The alignment unit 22 and the binding module 23 perform their corresponding actions in sequence. The left alignment module 221, right alignment module 222, front alignment module 223, and rear alignment module 224 of the alignment unit 22 simultaneously approach the edges of the board 200 and the spacers to align the board 200 and the spacers around their perimeter, making the sides of the board 200 and the spacers aligned. After the board and the spacers are aligned, the binding module 23 moves to the left corner of the board 200. The front and rear binding modules 23 first complete the binding action on the two left corners. Then the binding module 23 moves to the right corner of the board 200. The front and rear binding modules 23 first complete the binding action on the two right corners. After binding is completed, the second clamping module 83 of the third conveying mechanism 8 transports the board with the spacers to the material pulling trolley 20 of the receiving unit 5, and then removes the material pulling trolley 20 for subsequent stacking of photovoltaic modules.

[0074] 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.
