Description

Technical Field

[0001] This invention relates to the field of photovoltaic technology, and in particular to an automatic box-opening system and method suitable for photovoltaic raw material boxes. Background Technology

[0002] Photovoltaic cells are batteries that convert solar energy into electrical energy and have broad application prospects in the field of renewable energy.

[0003] With the iterative updates of automation technology, photovoltaic cell manufacturing workshops have largely replaced manual labor through the application of automation. However, there are still jobs for which there is no mature technology to replace them, and the unpacking process of photovoltaic raw material boxes is one of them.

[0004] Because machines cannot replicate the precision and appropriate force required for manual operation, specifically:

[0005] 1. When tearing off the external tape of the photovoltaic raw material box, the tape cannot be automatically cut.

[0006] 2. It cannot automatically retrieve and recycle photovoltaic material boxes;

[0007] 3. Unable to automatically retrieve and transport photovoltaic raw material wafers from the photovoltaic raw material box.

[0008] Therefore, the use of manual methods to open photovoltaic material boxes and manually pick up and move photovoltaic material sheets results in slow production efficiency and high costs. Summary of the Invention

[0009] Based on the above analysis, the present invention aims to provide an automatic unpacking system and method for photovoltaic raw material wafers, in order to solve the problems of slow production efficiency and high cost caused by the existing manual opening of raw material wafer boxes and manual handling and transportation of photovoltaic raw material wafers.

[0094] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0095] Example 1

[0096] This embodiment provides an automatic box opening system suitable for photovoltaic raw material boxes.

[0097] The photovoltaic material box comprises an upper part (i.e., the feeding box 700) and a lower part (i.e., the unloading box 800), and the feeding box 700 and the unloading box 800 are connected together with tape. A photovoltaic material package 600 is placed inside the photovoltaic material box, with the specific structure as follows... Figures 1-2As shown, the photovoltaic material package 600 includes multiple photovoltaic material sheets 500 placed vertically and attached to each other, and protective layers 400 disposed on both sides of the multiple photovoltaic material sheets 500. The multiple photovoltaic material sheets 500 and the protective layers 400 on both sides are tightly attached but not sticky to each other. The protective layer 400 includes a rigid layer 100, a buffer layer 200 and a contact layer 300, wherein the buffer layer 300 may have multiple layers.

[0098] This embodiment describes an automatic box-opening system applicable to photovoltaic raw material boxes. See [link to relevant documentation]. Figure 3 It includes a first conveying mechanism, and a cutting station, a side-flipping station, a flipping station, a supporting station and a stacking station arranged sequentially along the conveying direction of the photovoltaic raw material box.

[0099] The first conveying mechanism can adopt a conventional structure in the existing technology, such as a conveyor belt, conveyor roller, conveyor chain plate, etc.

[0100] See the cutting station. Figure 4 The device includes a lifting and rotating mechanism 2, a lower clamping mechanism 3, and a cutting assembly 1. The lifting and rotating mechanism 2 is located below the first conveying mechanism, the lower clamping mechanism 3 is located above the first conveying mechanism, and the cutting assembly 1 is located beside the first conveying mechanism. The lifting and rotating mechanism 2, the lower clamping mechanism 3, and the cutting assembly 1 work together to cut the tape at the connection of the photovoltaic raw material box, and the lower clamping mechanism 3 removes the loading box 700.

[0101] Among them, see Figure 10 The lifting and rotating mechanism 2 includes a lifting drive unit 21, a first horizontal rotating unit 23, a first clamping unit 24, and a top plate 22. The lifting drive unit 21 is connected to the first horizontal rotating unit 23 and can drive the first horizontal rotating unit 23 to rotate. The top plate 22 is disposed above the first horizontal rotating unit 23 and can drive the top plate 22 to rotate horizontally. The first clamping unit 24 is disposed on the top plate 22. The lifting drive unit 21 can be an electric lifting rod, or a linear motion device such as a cylinder or hydraulic cylinder, which can drive the top plate 22 of the lifting and rotating mechanism 2 to move upward, thereby moving the photovoltaic material box on the first conveying mechanism upward a certain distance, ensuring that the photovoltaic material box is separated from the first conveying mechanism by a certain height.

[0102] The first clamping unit 24 is disposed on the top plate 22 of the lifting and rotating mechanism 2. It can be a translational type, i.e., a clamp located on both sides or four sides of the top plate, which moves towards the center to clamp the photovoltaic material box when clamping is needed. It can also be a flipping type, located in or attached to the plane of the top plate, which flips upward to clamp the photovoltaic material box when clamping is needed. Alternatively, it can be a vacuum suction cup disposed on the upper surface of the top plate.

[0103] The first horizontal rotating unit 23 can drive the top plate 22 of the lifting and rotating mechanism 2 to rotate around the vertical central axis. Preferably, it is a gear drive mechanism. For example, a rotating shaft can be provided at the bottom of the top plate 22, and a gear can be sleeved on the rotating shaft. The gear can be driven by the drive mechanism to drive the rotating shaft to rotate.

[0104] See Figure 10 The lower clamping mechanism 3 includes a first lifting component 31, a second clamping unit 32, and a first translation component 33. The first lifting component 31 is mounted on the first translation component 33 and can move along it. The second clamping unit 32 is mounted on the first lifting component 31 and can be driven to rise or fall by the first lifting component 31. Specifically, the first lifting component 31 can drive the second clamping unit 32 downwards until the second clamping unit 32 can secure the loading box 700. The second clamping unit 32 can rotate relative to the first lifting component 31, and can rotate along with it when the lifting and rotating mechanism 2 drives the photovoltaic raw material box to rotate. The first translation component 33 may include a driving device and a horizontally extending track. The first lifting component 31 is mounted on the horizontally extending track and can move along the horizontally extending track with the second clamping unit 32.

[0105] The structure of the second clamping unit 32 may be the same as or different from the structure of the first clamping unit 24.

[0106] See Figures 4-9 The cutting assembly 1 is located beside the first conveying mechanism. The cutting assembly 1 can be fixedly mounted on the frame of the first conveying mechanism, or it can be mounted on a separate cutting table. See also... Figure 8The cutting assembly 1 includes a first support 10 extending horizontally, and a first roller 12 and a cutter 11 disposed on the first support 10. The first support 10 is elastically biased toward the direction in which the cutter 11 extends, so that the first roller 12 remains in contact with the outer surface of the photovoltaic material box during the opening process. Specifically, a set of first rollers 12 is disposed at the middle of the end of the first support 10, and a cutter 11 is disposed on one side of the end of the first support 10, wherein the end of the cutter 11 protrudes outward from the first rollers 12, preferably protruding between 1mm and 3mm. An elastic element 13 is disposed inside the first support 10, preferably a compression spring, one end of which is fixedly connected to the frame or cutting table on which the cutting assembly 1 is disposed, and the other end is fixedly connected to the first support 10, so that the first support 10 is elastically biased toward the direction in which the cutter 11 extends. When subjected to pressure, the first support 10 can retract in the direction opposite to the elastic force. This design allows the cutter 11 to float, maintaining constant contact with the outer surface of the photovoltaic material box. This ensures complete cutting of the tape while preventing damage to the photovoltaic material package 600. The cutting assembly 1 also includes a cutter drive device that drives the cutting assembly 1 forward or backward to achieve blade advance or retraction.

[0107] See Figure 9 Because the photovoltaic raw material box is square, the compression of the spring component is the greatest when it is rotated 360° horizontally to the diagonal position, and therefore the force it receives is also the greatest, resulting in the greatest friction. So the rolling of the first roller 12 is used to offset most of the friction, thus ensuring that the cutter 11 works normally.

[0108] To improve cutting accuracy, the cutting assembly 1 may also include a vision recognition system and a second lifting assembly (not shown in the figure). The vision recognition system can obtain the actual height of the connection part of the photovoltaic material box using image recognition technology, and based on the obtained actual height of the connection part, control the second lifting assembly to drive the first bracket 10 to move the cutter 11 up and down, so that the cutter 11 is exactly aligned with the connection part of the photovoltaic material box.

[0109] In some embodiments, the second lifting component may be omitted. After the visual recognition system obtains the actual height of the connection part of the photovoltaic raw material box based on image recognition technology, the lifting drive unit 21 is controlled to move up and down according to the obtained actual height of the connection part, and the height is adjusted so that the cutter 11 is exactly aligned with the connection part of the photovoltaic raw material box.

[0110] With the above setup, when the photovoltaic raw material box is conveyed to the cutting station by the first conveying mechanism, the lifting drive unit 21 of the lifting and rotating mechanism 2 drives the top plate 22 to raise the photovoltaic raw material box to a certain height. The first clamping unit 24 clamps the unloading box 800. The lower clamping mechanism 3 moves downward, and then drives the second clamping unit 32 to clamp the loading box 700.

[0111] The cutting assembly 1 uses a visual recognition system and a second lifting assembly to adjust the height of the cutter 11. Then, the cutter drive device drives the cutter 11 to complete the cutting action, so that the first roller 12 of the cutting assembly 1 abuts against the outer surface of the photovoltaic raw material box. At this time, the cutter 11 cuts into the tape at the connection between the upper material box 700 and the lower material box 800.

[0112] Then, the first horizontal rotating unit 23 drives the top plate 22 to rotate the photovoltaic material box 360°. Under the action of the elastic element 13, the cutter 11 continuously cuts the tape along the connecting part. Since the first roller 12 is always in contact with the outer surface of the photovoltaic material box, the cutter 11 will always maintain a suitable cutting depth, ensuring that the tape is continuously cut without damaging the photovoltaic material package 600.

[0113] After the cutting is completed, see Figure 11 The lower clamping mechanism 3 first raises the upper material box 700 to detach it from the photovoltaic raw material package 600, then moves horizontally to the position where the upper material box 700 is recycled, and then lowers the upper material box 700.

[0114] See Figure 12 At the side-tilting station, a first vertical rotation mechanism 4 and a fixing mechanism 5 are provided. The first vertical rotation mechanism 4 is located at the output end of the first conveying mechanism, and the fixing mechanism 5 is located above the first vertical rotation mechanism 4; the first vertical rotation mechanism 4 causes the unloading box to tilt sideways with the photovoltaic raw material package, and the fixing mechanism 5 can remove the unloading box.

[0115] In this embodiment, the first vertical rotation mechanism 4 includes a first receiving platform 41 and a second receiving platform 42, which are perpendicular to each other and fixedly connected at their ends by a first rotating shaft. The first vertical rotation mechanism 4 can rotate around the first rotating shaft. The connecting line between the first receiving platform 41 and the second receiving platform 42 is a horizontally extending first rotating shaft 43, which is perpendicular to the conveying direction of the first conveying mechanism. The first receiving platform 41 and the second receiving platform 42 rotate around the first rotating shaft 43 between a first position and a second position. At the first position, the first receiving platform 41 extends horizontally, and the second receiving platform 42 extends vertically upward. At the second position, the second receiving platform 42 extends horizontally, and the first receiving platform 41 extends vertically upward. The function of the first vertical rotation mechanism 4 is to rotate the photovoltaic material box vertically by 90°, so that the photovoltaic material package 600 is placed horizontally. The purpose is to make the photovoltaic material package 600 easy to remove, preventing it from falling due to gravity or breaking due to excessive clamping force.

[0116] It should be noted that a second roller 44 is provided on the surface of the second receiving platform 42 facing the first receiving platform 41, and the second roller 44 is close to the free end of the second receiving platform 42. The size of the second roller 44 is such that when one side of the photovoltaic material box abuts against the surface of the second receiving platform 42, the side of the photovoltaic material package 600 abuts against the second roller 44. This arrangement ensures that during a 90° vertical rotation, the portion of the photovoltaic material package 600 outside the unloading box 800 has a support point, preventing it from sliding sideways or developing microcracks due to uneven stress. Furthermore, after a 90° sideways rotation, as the second vertical rotation mechanism removes the photovoltaic material package 600 horizontally from the unloading box 800, the second roller 44 reduces friction.

[0117] Preferably, two second rollers 44 can be provided, arranged in parallel at intervals.

[0118] Furthermore, the second rollers 44 can be arranged in two rows, along the direction from the upper edge of the feed box 800 to the free end of the second receiving platform 42, and each row of the second rollers can be provided with two or more.

[0119] See Figures 12-13 The fixing mechanism 5 includes a third lifting assembly 52, a third clamping unit 53, and a second translation assembly 51. The third lifting assembly 52 drives the third clamping unit 53 downwards until it secures the unloading box 800. The second translation assembly 51 may include a drive device and a horizontally extending track. The third lifting assembly 52 is positioned on this horizontally extending track and can move the third clamping unit 53 along it. The third clamping unit 53 may also include a vacuum suction cup or a Bernoulli suction cup, which can move the unloading box 800 upwards and then horizontally, transporting the unloading box 800 to the recycling position and lowering it down.

[0120] In some preferred embodiments, in order to simplify the system and reduce costs, the fixing mechanism 5 and the lower clamping mechanism 3 can be the same mechanism, as long as its movement trajectory can reach the cutting station, the side-flipping station, and the recycling positions of the loading box 700 and the unloading box 800.

[0121] See Figure 14 At the flipping station, a second vertical rotation mechanism 6 is provided. The second vertical rotation mechanism 6 can remove the photovoltaic raw material package from the unloading box from the side-flipping station and place it at the next station after the flipping station.

[0122] The second vertical rotation mechanism 6 includes a second support, a third translation component 61 disposed at the bottom of the second support, a second rotating shaft 62 disposed at the top of the second support, and a fourth clamping unit 63 connected to the second rotating shaft 62. The fourth clamping unit 63 can rotate around the second rotating shaft. The second rotating shaft 62 extends horizontally and is perpendicular to the conveying direction of the first conveying mechanism. The fourth clamping unit 63 can rotate around the second rotating shaft 62 between a third position and a fourth position. When the fourth clamping unit 63 is in the third position, its opening faces the tilting station. When the fourth clamping unit 63 is in the fourth position, its opening faces the supporting station. The third translation component 61 can drive the fourth clamping unit 63 to move back and forth between the tilting station and the supporting station. When it controls the fourth clamping unit 63 to move towards the tilting station, it positions the fourth clamping unit 63 in the third position. When it controls the fourth clamping unit 63 to move towards the supporting station, it positions the fourth clamping unit 63 in the fourth position.

[0123] The fourth clamping unit 63 clamps the photovoltaic raw material package 600 from both sides. The shape and structure of the jaws on the side of the fourth clamping unit 63 adjacent to the side-flipping station are suitable for insertion between or outside the second rollers 44 of the first vertical rotation mechanism 4, and the shape and structure of the jaws on the side of the support station are suitable for insertion into the support platform 7 of the support station.

[0124] For example, the first vertical rotation mechanism 4 has two second rollers 44 at the same height, spaced apart, with each roller 44 located at a corner of the photovoltaic material package 600. The gripper on one side of the fourth clamping unit 63, adjacent to the side-flipping station, extends from between the two second rollers into the space between the photovoltaic material package 600 and the second receiving platform 42, while the gripper on the other side adheres to the photovoltaic material package 600 from its upper side. When the fourth clamping unit 63 rotates clockwise to the fourth position, the lower gripper is inserted between the support columns on both sides of the support platform into the interior of the support platform, thereby placing the photovoltaic material package 600 onto the support platform.

[0125] Depending on the needs and without interfering, the second vertical rotation mechanism 6 can move and rotate simultaneously, or it can first move to the rotation station, rotate 180° in place, and then continue to move to the target position.

[0126] During the rotation of the second vertical rotating mechanism 6, not only can the photovoltaic raw material package 600 be moved along the conveying direction, but also the layers of the photovoltaic raw material package 600 can be aligned, reducing the unevenness between the layers caused by the previous side-flipping and picking actions.

[0127] See Figure 14 , Figure 16At the support station, a support platform 7 and a gripper mechanism 8 are provided. The gripper mechanism is movably positioned above the support platform 7.

[0128] In this embodiment, see Figure 14 The support platform 7 includes a support column 71, a platform 72, and protrusions 73. The protrusions 73 are fixed to the four corners of the platform 72 on top of the support column 71. The purpose of the support platform 7 is to support the photovoltaic material package 600 from its four corners. The support platform 7 is designed with a four-corner support style to facilitate the gripper mechanism 8 to grip the material wafer assembly by rotating it horizontally by 90° or without rotation (depending on the on-site requirements for the direction of the markings on the material wafers).

[0129] See Figure 16 The gripper mechanism 8 is located at the top and has a fifth gripping unit 83. The fifth gripping unit 83 includes two side portions 84, which are rotatable and can open outward or close inward. The bottom of the two side portions 84 has an inwardly extending support plate 85, which can support the photovoltaic material package 600 from the bottom. During the downward movement of the gripper mechanism 8, the two side portions 84 open outward. After landing in place, the two side portions 84 close inward, and the support plate 85 extends from the hollow position of the support platform 7, clamping into the bottom of the photovoltaic material package 600. Then, it drives the photovoltaic material package 600 to move upward and places the photovoltaic material package 600 into the empty stacking box.

[0130] The gripper mechanism 8 also includes a fourth lifting assembly 82 and a fourth translation assembly 81. The fourth lifting assembly 82 is movably mounted on the fourth translation assembly 81. A fifth gripping unit 83 is mounted on the fourth lifting assembly 82.

[0131] In some preferred embodiments, the gripper mechanism 8 further includes a second horizontal rotation unit 86, and the fifth gripping unit 83 is connected to the fourth lifting assembly 82 via the second horizontal rotation unit 86. This arrangement allows the fifth gripping unit 83 to rotate in the horizontal plane to meet the requirements of subsequent processes.

[0132] See Figure 18 The next station after the support station is the stacking station, which is equipped with a stacking box and a suction cup mechanism. The suction cup mechanism is movably positioned above the stacking box. The system provided in this embodiment also includes a second conveying mechanism located downstream of the support platform, with a gripper mechanism movable above the second conveying mechanism; and / or the stacking box is mounted on the second conveying mechanism. The stacking box can also be located in other positions, such as on a workbench. The suction cup mechanism is movably positioned above the stacking box.

[0133] The stacking box can be a triple box, a quad box, or a combination of other numbers of boxes. Of course, it can also be a single box. Using a multi-box structure, the relative positions between each pair of boxes are fixed. The suction cup mechanism 9 can be equipped with multiple suction cup units 94 to simultaneously pick up the protective layer 400 from the photovoltaic material packages 600 in multiple stacking boxes, thereby improving production efficiency.

[0134] Furthermore, the suction cup mechanism 9 includes a fifth lifting component 92, a fifth translation component 91, a connector 93, and a suction cup unit 94. The fifth lifting component 92 is disposed on the fifth translation component 91, and the suction cup unit 94 is disposed on the fifth lifting component 92 via the connector 93.

[0135] See appendix Figure 19 The suction cup mechanism 9 moves above the stacking box containing the photovoltaic raw material package 600. The fifth lifting component 92 drives the suction cup unit 94 to move downward. After the suction cup unit 94 picks up the upper protective layer 400 of the photovoltaic raw material package 600, it carries the upper protective layer 400 upward, separating the upper protective layer 400 from the photovoltaic raw material wafer 500. Then, the upper protective layer 400 is placed on the protective layer 400 recycling track.

[0136] The suction cup mechanism 9 moves above the stacking box containing the lower protective layer 400. The fifth lifting component 92 drives the suction cup unit 94 to move downward. After the suction cup unit 94 picks up the lower protective layer 400 of the photovoltaic raw material package 600, it carries the lower protective layer 400 upward and then places the lower protective layer 400 on the protective layer 400 recycling track.

[0137] The automatic box-opening system for photovoltaic raw material boxes in this embodiment also includes a control unit. The control unit is electrically connected to all the moving elements and sensing elements in the system, and can automatically control the entire box-opening system according to the sensed signals and through a pre-set control program.

[0138] Example 2

[0139] like Figures 2-19 As shown, the automatic box opening method using the automatic box opening system for photovoltaic raw material boxes as described in Example 1 includes the following steps:

[0140] S1: The tape connecting the feed box 700 and the unfeed box 800 is automatically cut by the cutting component 1, and the feed box 700 is retrieved by the lower clamping mechanism 3. Figure 2 (a)-(c) and Figures 4-11 As shown;

[0141] S2: The photovoltaic raw material package 600 is removed from the feeding box 800 by the second vertical rotation mechanism 6, and the feeding box 800 is recovered by the fixing mechanism 5. Figure 2(d)-(e) and Figures 12-15 As shown;

[0142] S3: The photovoltaic raw material package 600 is transported to the next station after the flipping station via the second vertical rotation mechanism 6, such as... Figure 2 (f) and Figures 16-17 As shown.

[0143] The automatic box opening method of the present invention can transform the manual box opening process in the prior art into a fully automatic box opening production line. The operation is fast, stable and reliable. It can also recover the loading box 700 and the unloading box 800 respectively, and automatically transport the photovoltaic raw material 500 to the next station, thereby improving production efficiency, reducing costs and improving product quality, and promoting the sustainable development of the photovoltaic cell manufacturing industry.

[0144] Among them, see Figure 2 as well as Figures 4-10 Step S1 includes the following process:

[0145] S11: The photovoltaic material box is conveyed to the cutting station via the first conveying mechanism, such as... Figure 2 (a) and Figure 4 As shown;

[0146] S12: The photovoltaic material box is lifted to a certain height away from the first conveying mechanism by the lifting and rotating mechanism 2, such as... Figure 5 As shown;

[0147] S13: The bottom of the photovoltaic material box is clamped by the lifting and rotating mechanism 2, and the top of the photovoltaic material box is clamped by the lower clamping mechanism 3. Figure 5 As shown;

[0148] S14: The feed cutter, driven by the lifting and rotating mechanism 2, rotates the photovoltaic material box horizontally 360°. Simultaneously, the cutting component 1 cuts the tape at the connection between the upper and lower boxes of the photovoltaic material box (700 and 800). The feed cutter retracts... Figure 2 (b) and Figures 6-9 As shown;

[0149] S15: The feeding box 700 of the photovoltaic raw material box is transported to the recycling position by the lower clamping mechanism 3, such as... Figure 2 (c) and Figures 10-11 As shown.

[0150] The photovoltaic raw material box is conveyed via a first conveying mechanism, which can be a conventional conveying device such as a conveyor belt, conveyor roller, or conveyor chain. When the photovoltaic raw material box is conveyed to its designated position, a detection mechanism detects it and sends this signal to a control unit. The control unit then initiates the next step, controlling the lifting and rotating mechanism 2 to lift the photovoltaic raw material box to a certain height. This allows the photovoltaic raw material box to rotate freely without hindrance after being moved a certain height away from the first conveying mechanism.

[0151] Then, the grippers at the top of the lifting and rotating mechanism 2 clamp the bottom of the unloading box 800, and the upper clamping element, namely the lower clamping mechanism 3, moves downwards towards the loading box 700, clamping the loading box 700 from the top. After the clamping action is completed, the cutter 1 advances to the connection between the loading box 700 and the unloading box 800, cutting the tape at that point. Then, the lifting and rotating mechanism 2 begins to rotate horizontally in place, its rotation axis located at the center of the photovoltaic material box and extending vertically, causing the photovoltaic material box to rotate 360° horizontally. During this process, the cutter remains against the connection between the loading box 700 and the unloading box 800, completely cutting the entire circle of tape. After the cutting action is completed, the cutter is retracted to avoid scratching the loading box 700, the unloading box 800, and the photovoltaic material package 600 within them.

[0152] After cutting, the lower clamping mechanism 3, via a vacuum suction cup positioned on top of the upper feeding box 700, moves the feeding box 700 upwards. After detaching the feeding box 700 from the photovoltaic raw material package 600, it then moves the feeding box 700 horizontally, transporting it to the recycling location. Figure 11 As shown.

[0153] See Figures 12-13 Step S2 includes the following process:

[0154] S21: The feeding box 800 and the photovoltaic raw material package 600 are conveyed to the first vertical rotation mechanism 4 at the side-tilting station via the first conveying mechanism, as follows: Figure 12 As shown;

[0155] S22: The first vertical rotating mechanism 4 rotates 90° clockwise around the horizontal axis, as shown. Figure 13 As shown in the first step;

[0156] S23: The fixing mechanism 5 moves down, fixing the feeding box 800, such as Figure 13 The second step is shown in the diagram;

[0157] S24: The second vertical rotation mechanism 6 translates toward the first vertical rotation mechanism 4, and its fourth clamping unit 63 clamps the photovoltaic raw material package 600 from the upper and lower sides, then translates in the opposite direction to remove the photovoltaic raw material package 600 from the unloading box 800. Figure 13The second, third, and fourth steps are shown in the diagram;

[0158] S25: The fixing mechanism 5 removes the feed box 800 using a suction cup and transports it to the recycling location, such as... Figure 13 As shown in step 5 of the process.

[0159] At this point, the feed box 700 of the photovoltaic raw material box has been removed, leaving only the feed box 800 and the photovoltaic raw material package 600 contained within it. It is now necessary to separate the feed box 800 from the photovoltaic raw material package 600. However, if the photovoltaic raw material package 600 is directly clamped and lifted upwards using a clamp, the protective layer 400 in the photovoltaic raw material package 600 is not bonded to the photovoltaic raw material sheet 500, nor to adjacent photovoltaic raw material sheets 500. Furthermore, the photovoltaic raw material sheet 500 has a smooth surface and is hard and brittle. Therefore, if the clamping force is too weak, the middle photovoltaic raw material sheet 500 will easily fall due to gravity; if the clamping force is too strong, the photovoltaic raw material sheet 500 will break, ultimately making it impossible to remove the photovoltaic raw material package 600.

[0160] To separate the feeding box 800 from the photovoltaic raw material package 600, this invention provides a separation method. First, the feeding box 800 and the photovoltaic raw material package 600 are conveyed to a first vertical rotation mechanism 4. The first vertical rotation mechanism 4 drives the feeding box 800 and the photovoltaic raw material package 600 to rotate 90° clockwise around a horizontal axis. This step changes the photovoltaic raw material package 600 from a vertical position to a horizontal position. Then, by clamping the photovoltaic raw material package 600 from the bottom and top with clamps, the situation described above can be avoided, and the photovoltaic raw material package 600 can be easily removed from the feeding box 800.

[0161] To prevent the feeding box 800 from moving due to friction with the photovoltaic raw material package 600, the upper fixing mechanism 5 moves down and presses against the upper surface of the feeding box 800, thereby fixing the feeding box 800 and making it easier to remove the photovoltaic raw material package 600.

[0162] Next, the photovoltaic raw material package 600 is removed from the feeding box 800 by the second vertical rotation mechanism 6. Then, the feeding box 800 is removed by the vacuum suction cup set on the fixing mechanism 5 and transported to the recycling position.

[0163] like Figures 15-17 As shown, step S3 includes the following process:

[0164] S31: The photovoltaic raw material package 600 is translated along the conveying direction of the second vertical rotation mechanism 6, while the second vertical rotation mechanism rotates 180° clockwise around the horizontal axis, placing the photovoltaic raw material package 600 onto the support platform 7 located at the next station after the flipping station, as shown. Figure 15 As shown;

[0165] S32: The photovoltaic material package 600 is released by the second vertical rotation mechanism 6 and moved in the opposite direction, leaving the photovoltaic material package 600 on the support platform 7. Figure 15 As shown;

[0166] S33: The next station after the flipping station is the support station. A gripper mechanism located above the support station picks up the photovoltaic material package from both sides at the bottom and places it into the stacking box of the stacking station located behind the support station. Figure 17 As shown.

[0167] After the second vertical rotating mechanism 6 removes the photovoltaic raw material package 600 from the unloading box 800, it translates along the conveying direction of the photovoltaic raw material package 600 while simultaneously rotating 180° clockwise around a horizontal axis, placing the photovoltaic raw material package 600 onto the support platform 7. This process achieves both the displacement of the photovoltaic raw material package 600 along the assembly line and the alignment of the various layers within the photovoltaic raw material package 600, eliminating the misalignment between the layers caused by tipping and friction during handling in the previous step.

[0168] Then, the second vertical rotation mechanism 6 releases the photovoltaic material package 600, moves in the opposite direction, and leaves the photovoltaic material package 600 on the support platform 7. The support platform 7 is a four-corner support device that supports the photovoltaic material package 600 from its four corners. This structure facilitates the loading and unloading of the photovoltaic material package 600.

[0169] See Figure 16 The gripper mechanism 8 is located at the top and has two rotatable sides 84, which can open outward or close inward. The bottom of each side 84 has an inwardly extending support plate 85 that can support the photovoltaic material package 600 from the bottom. During the downward movement of the gripper mechanism 8, the two sides 84 open outward; after landing, they close inward, and the support plate 85 extends from the hollow position of the support platform 7, engaging the bottom of the photovoltaic material package 600. This then moves the photovoltaic material package 600 upward and places it into an empty stacking box.

[0170] Through the above steps, the feeding box 700 and the unloading box 800 can be automatically recycled respectively, and the photovoltaic raw material package 600 can be placed into the stacking box for easy access, which facilitates the next process.

[0171] See Figure 19 The automatic box opening method may also include step S4: recycling the protective layer 400, specifically including:

[0172] The protective layer 400 located on the upper surface of the photovoltaic raw material package 600 is removed and recycled by the suction cup mechanism 9;

[0173] The photovoltaic raw material wafer 500 is sent to the next process via the second conveying mechanism;

[0174] After the photovoltaic raw material wafers 500 are removed and returned in the next process, the protective layer 400 located on the lower surface of the photovoltaic raw material package 600 is removed and recycled by the suction cup mechanism 9.

[0175] Example 3

[0176] Based on Example 2, in step S22, the rotation speed does not exceed 90° / second, and in step S31, the rotation speed does not exceed 90° / second. This setting prevents displacement and misalignment between the protective layer 400 and the photovoltaic raw material wafer 500, or between adjacent photovoltaic raw material wafers 500, during the flipping process, and also prevents the photovoltaic raw material package 600 from being thrown out of the box.

[0177] Furthermore, in step S14, before the cutting blade enters the feed box, the height of the photovoltaic raw material box is first identified, and then the height of the blade is adjusted according to the identification result so that the blade is aligned with the connection between the feed box 700 and the feed box 800. This setting allows the blade to adapt to the height error of the photovoltaic raw material box, ensuring precise alignment of the cutting position.

[0178] Step S2 also includes step S26: driving the first vertical rotation mechanism 4 to rotate 90° counterclockwise around the horizontal axis and return to the initial position.

[0179] Step S3 also includes step S34: controlling the second vertical rotation mechanism 6 to translate to the middle position, while rotating 180° counterclockwise around the horizontal axis to return to the initial position.

[0180] With the above settings, the first vertical rotation mechanism 4 and the second vertical rotation mechanism 6 can be automatically reset and ready for the next operation, making the whole process smooth and improving efficiency.

[0181] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
