[0056] In the present invention, unless otherwise specified, directional words such as "up, down, left, right" are generally understood in conjunction with the directions shown in the drawings and actual applications.

[0057] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0058] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0059] The endpoints of the ranges and any values ​​disclosed herein are not limited to the precise ranges or values, and these ranges or values ​​should be understood to include values ​​close to these ranges or values. For numerical ranges, the endpoints of each range, the endpoints of each range and individual point values, and the individual point values ​​can be combined to form one or more new numerical ranges, and these numerical ranges should be considered to be specifically disclosed herein. The terms "optional" and "optional" mean that a range may or may not be included (or may or may not be present).

[0060] The flexible solar cell involved in the embodiments of the present invention is rectangular and includes a protective layer, adhesive, and silicon wafer stacked in sequence. Both the protective layer and the silicon wafer are provided with aligned scratches to facilitate subsequent breaking of the multiple wafers, improving wafer production efficiency. The protective layer can be made of materials such as glass or resin, which is not limited in the present invention.

[0061] It should be noted that before the battery cell enters the splitting process, laser or diamond scribing methods are required to form aligned scratches on the protective layer and the silicon wafer.

[0062] Specifically, there are multiple scratches, including multiple first scratches and multiple second scratches, the multiple first scratches are arranged in parallel and at equal intervals, the multiple second scratches are arranged in parallel and at equal intervals, the first scratches are perpendicular to the second scratches, and the multiple first scratches and the multiple second scratches work together to form a grid-shaped stress notch on the flexible battery sheet, which is convenient for cutting into small pieces.

[0063] An embodiment of the present invention provides an automatic horizontal and vertical wafer splitting device 10 for splitting the protective layer and silicon wafer in the three-layer structure of a solar cell without breaking the adhesive in the middle. This allows the split solar cell to remain adhered. At this point, the solar cell as a whole is in a semi-fractured state (i.e., seemingly broken but not broken), maintaining the integrity of the solar cell without breaking into small particles. This facilitates the circulation of the solar cell and provides conditions for subsequent full-scale breaking, shaping, and extended-length lamination production. The present invention has a high degree of automation and can effectively increase production capacity and improve product quality.

[0064] The following details why the present invention requires the protective layer and the silicon wafer to be cleaved, rather than the adhesive in between:

[0065] Back-contact flexible module cells are solar cells. During the production process, the cell sheet must first be broken into multiple small pieces. A predetermined number of these pieces are then bonded to a flexible circuit board, with a certain gap between adjacent pieces, to form the back-contact flexible module cell. This allows the back-contact flexible module cell to be used by unfolding the flexible circuit board, allowing the multiple small pieces to be spread out flat, increasing the area of ​​contact between the small pieces and sunlight, thereby achieving the photovoltaic power generation function of the back-contact flexible module cell and ensuring power generation efficiency. When the back-contact flexible module cell is no longer in use, the flexible circuit board is rolled up for storage, saving space. During this process, since there is a certain gap between adjacent small pieces, the small pieces will not interfere with the rolling of the flexible circuit board, making it easier to store the back-contact flexible module cell.

[0066] Based on the above situation, breaking the battery cell into multiple small pieces is a key process for achieving flexible batteries. However, the existing technology uses a single-step splitting process, which specifically requires two improvements. First, completely splitting a large battery cell into small cells in one go requires a lot of pressure, which can easily cause the cell to crack and cause defects. Second, splitting the cell into small pieces in one go makes it inconvenient to transfer the cell to subsequent processes.

[0067] In order to solve the technical problems existing in the single-splitting process, the inventors of the present invention creatively invented a secondary splitting process. The first splitting process splits the protective layer and the silicon wafer in the three-layer structure of the battery cell, keeping the adhesive in the middle still bonded, and the second splitting process breaks the adhesive again. The use of the secondary splitting process can significantly reduce the pressure required in the splitting process, avoiding defects caused by the fracturing of the battery cell due to excessive pressure. After the first splitting process splits the protective layer and the silicon wafer, the structure of the battery cell still maintains a certain integrity, which makes the battery cell easier to handle and circulate in subsequent processes. It provides a strong guarantee for all subsequent production links such as splitting, shaping, and expansion coating, and also greatly improves production efficiency and product quality.

[0068] In order to achieve the above purpose, Figures 1 to 4 As shown, the present invention provides an automatic horizontal and vertical splitting device for flexible module solar cells. The automatic horizontal and vertical splitting device 10 includes a frame 100, a conveying mechanism 110, a first splitting mechanism 120, and a second splitting mechanism 130. The conveying mechanism 110 is disposed on the frame 100. The first splitting mechanism 120 and the second splitting mechanism 130 are sequentially disposed on the conveying mechanism 110 along the conveying direction of the conveying mechanism 110. The conveying mechanism 110 is used to transport the solar cells along the conveying direction. The first splitting mechanism 120 is used to break the protective layer and the silicon wafer along the scratch marks in a first direction to split the solar cell into multiple strips connected by adhesive. The second splitting mechanism 130 is used to break the protective layer and the silicon wafer along the scratch marks in a second direction to split the multiple solar cells into multiple small solar cells connected by adhesive. The first direction and the second direction are perpendicular to each other. The present invention achieves fully automated production without human intervention, with the advantages of reducing costs, improving product quality, and increasing production efficiency.

[0069] It should be noted that the first direction and the second direction may be the width direction or the length direction of the battery cell, respectively and independently.

Multiple fixed seats 111 are evenly spaced below the conveyor belt support plate 1161 to support the conveyor belt support plate 1161. Preferably, there are five fixed seats 111. The conveyor belt 116 is disposed within the conveyor belt support plate 1161. The fourth drive member 112 is disposed at the starting end of the conveyor belt 116. The fourth drive member 112 is fixed below the conveyor belt 116 via a fourth drive member fixing plate 1121. One end of the fourth drive member 112 is connected to a synchronous pulley 113, which is connected to another synchronous pulley 113 via a synchronous belt 114. The other synchronous pulley 113 drives the driving pulley 115 to rotate. The driving pulley 115 is connected to a driven pulley 117 via the conveyor belt 116. A tensioning pulley 118 is also disposed in the middle of the conveyor belt 116. Among them, the driving wheel 115 is fixed to the conveyor belt support plate 1161 through the driving wheel fixing plate 1151, the driven wheel 117 is fixed to the conveyor belt support plate 1161 through the driven wheel fixing plate 1171, and the tensioning wheel 118 is fixed to the conveyor belt support plate 1161 through the tensioning wheel fixing plate 1181.

[0072] The driving pulley 115 is not directly connected to the fourth driving member 112 but is driven by the synchronous pulley 113 in order to reduce mechanical shock, improve transmission efficiency, and facilitate maintenance and adjustment. The tensioning pulley 118 is provided to maintain belt tension, compensate for belt elongation, reduce belt vibration, and extend belt life.

[0073] Preferably, the first splitting mechanism 120 includes a first support seat, a first driving member 122, a first connecting member, a first rolling wheel 124, a first follower belt 125 and two first follower pulleys 126, the first support seat is arranged on the conveying mechanism 110, the first driving member 122 is arranged on the first support seat, the top of the first connecting member is connected to the first driving member 122, the bottom of the first connecting member extends from both sides of the conveying mechanism 110 into the bottom surface of the conveying mechanism 110, the first rolling wheel 124 is arranged at the bottom of the first connecting member, the first follower belt 125 is arranged at the bottom of the first connecting member, and the first follower belt 125 is arranged at the bottom of the first connecting member. Placed above the top surface of the conveying mechanism 110, two first follower pulleys 126 are respectively arranged at the two ends of the first follower belt 125; wherein, the first driving member 122 drives the first rolling wheel 124 to rise through the first connecting member, and the first rolling wheel 124 abuts against the bottom surface of the conveying mechanism 110 to make the top surface of the conveying mechanism 110 protrude to form an angle. When the battery cell enters the gap between the top surface of the conveying mechanism 110 and the first follower belt 125, the angle breaks the protective layer and the silicon wafer along the scratch from the first direction to split the battery cell into multiple strips connected by adhesive.

[0074] Specifically, if Figure 3 and Figure 4As shown in the figure, the first support base is composed of two first fixing plates 1211 and a first connecting plate 1212. The two first fixing plates 1211 are respectively vertically arranged on both sides of the conveyor belt support plate 1161, and both ends of the first connecting plate 1212 are respectively connected to the two first fixing plates 1211. The first driving member 122 is arranged in the middle of the top surface of the first connecting plate 1212. The first connecting member is composed of a first rolling wheel connecting plate 1231 and a first rolling wheel fixing plate 1232. The bottom of the first driving member 122 is a movable end, and the bottom of the first driving member 122 is connected to the top of the first rolling wheel connecting plate 1231. The bottom of the first rolling wheel connecting plate 1231 is connected to the first rolling wheel fixing plate 1232. Both ends of the first rolling wheel fixing plate 1232 are respectively located in the gaps between both sides of the conveyor belt 116 and the conveyor belt support plate 1161 and respectively extend downward to form two parts that extend into the bottom surface of the conveyor belt 116. The first rolling wheel fixing plate 1232 is formed into a structure similar to the Chinese character "冂". Both ends of the first rolling wheel 124 are respectively connected to the two bottoms of the first rolling wheel fixing plate 1232. A first idler wheel support plate 1271 is further arranged on the inner side of the conveyor belt support plate 1161. The first idler wheel support plate 1271 has through grooves matching the two bottoms of the first rolling wheel fixing plate 1232 to facilitate the up and down movement of the two bottoms of the first rolling wheel fixing plate 1232. At the same time, two first idler wheels 127 are respectively and fixedly arranged on both sides of the first rolling wheel 124 on the first idler wheel support plate 1271, and the tops of the two first idler wheels 127 are abutted against the conveyor belt 116.

[0075] Among them, the two bottoms of the first rolling wheel fixing plate 1232 need to be arranged in the gaps between both sides of the conveyor belt 116 and the conveyor belt support plate 1161. In this way, when the first driving member 122 lifts the first rolling wheel 124, it can ensure that the first rolling wheel 124 can be abutted against the bottom of the conveyor belt 116, so as to ensure that an included angle is formed by the protrusion of the top surface of the conveyor belt 116. The first idler wheel support plate 1271 does not necessarily need to be arranged on the inner side of the conveyor belt support plate 1161, but the preferred arrangement in the present invention can make the mechanical structure compact and avoid mutual influence between components at the same time. The two first idler wheels 127 are naturally abutted against the conveyor belt 116, which can assist in transmission and guiding, ensure the stable operation of the belt, and reduce wear.

[0076] It should be noted that as Figure 5As shown, the first follower belt 125 is set above the top surface of the conveyor belt 116 through the first follower belt support plate 1251. The width of the gap between the conveyor belt 116 and the first follower belt 125 should be slightly larger than the thickness of the battery cell. Preferably, the width of the gap should be greater than 1mm, and more preferably, the width of the gap is 2mm-10mm. If the gap width is too small, the battery cell cannot enter the gap between the conveyor belt 116 and the first follower belt 125, resulting in the inability to split the battery cell. If the gap width is too large, when the first rolling wheel 124 lifts the conveyor belt 116, the first follower belt 125 cannot fit tightly against the top surface of the battery cell, resulting in the inability to play a good pressing role, thereby affecting the splitting effect, and may even cause some scratches to not be broken.

[0077] Further, if Figure 5 As shown, the angle formed by the protrusion of the top surface of the conveyor belt 116 ranges from 130° to 170°, more preferably, the angle ranges from 140° to 160°, and more preferably, the angle is 150°. It should be noted that the angle here refers to the angle formed between the conveyor belts on both sides of the raised portion of the conveyor belt 116. If the angle is too small, the battery cell may not be able to break smoothly when passing through the angle, resulting in poor splitting effect, or even the battery cell may not be completely broken. If the angle is too large, the battery cell may be subjected to excessive stress when passing through the angle, resulting in damage to the battery cell and affecting the subsequent process.

[0078] Preferably, the first splitting mechanism 120 further includes two first detection switches 128, which are respectively provided at both ends of the first follower belt 125 and are respectively used to detect the battery cells entering and leaving the first splitting mechanism 120. Specifically, the two first detection switches 128 are respectively provided at both ends of the first follower belt 125 via two first detection switch fixing plates 1281. When the battery cells are detected to have entered, the first driving member 122 drives the first rolling wheel 124 to rise via the first connecting member. When the battery cells are detected to have completely left, the first driving member 122 drives the first rolling wheel 124 to descend via the first connecting member.

[0079] Preferably, the second splitting mechanism 130 includes a second support seat, a second driving member, a second connecting member, a second rolling wheel, a second follower belt and two second follower pulleys, the second support seat is arranged on the conveying mechanism 110, the second driving member is arranged on the second support seat, the top of the second connecting member is connected to the second driving member, the bottom of the second connecting member extends into the bottom surface of the conveying mechanism 110 from both sides of the conveying mechanism 110, the second rolling wheel is arranged at the bottom of the second connecting member, the second follower belt is arranged above the top surface of the conveying mechanism 110, and the two second follower pulleys are respectively arranged at both ends of the second follower belt; wherein, the second driving member drives the second rolling wheel to rise through the second connecting member, the second rolling wheel abuts against the bottom surface of the conveying mechanism 110 so that the top surface of the conveying mechanism 110 protrudes to form an angle, when multiple battery cells enter the gap between the top surface of the conveying mechanism 110 and the second follower belt, the angle breaks the protective layer and the silicon wafer along the scratch from the second direction to split the multiple battery cells into multiple small battery cells connected to each other by adhesive.

[0080] Preferably, the second splitting mechanism 130 further includes two second detection switches, which are respectively provided at both ends of the second follower belt and are used to detect the battery cells entering and leaving the second splitting mechanism 130 .

[0081] In this embodiment, the specific structure of the second splitting mechanism 130 is the same as that of the first splitting mechanism 120 , except for the splitting direction, which will not be described again.

[0082] Preferably, the automatic horizontal and vertical splitting device 10 also includes a turning mechanism 140, which is arranged between the first splitting mechanism 120 and the second splitting mechanism 130. The turning mechanism 140 includes a third support seat and an arc-shaped rib 142. The third support seat is arranged on the conveying mechanism 110, and the top of the arc-shaped rib 142 is connected to the third support seat, and the bottom of the arc-shaped rib 142 is close to the top surface of the conveying mechanism 110; wherein, when the battery cell moves along the conveying direction of the conveying mechanism 110, after one corner of the battery cell abuts against the arc-shaped rib 142, the battery cell gradually rotates 90 degrees during transportation.

[0083] Specifically, if Figure 6 As shown, the third support base is composed of two third fixing plates 1411 and a third connecting plate 1412. The two third fixing plates 1411 are vertically arranged on both sides of the conveyor belt support plate 1161, and the two ends of the third connecting plate 1412 are respectively connected to the two third fixing plates 1411. The top of the arcuate rib 142 is connected to the top inner side surface of the third connecting plate 1412, and the bottom of the arcuate rib 142 is close to the top surface of the conveyor mechanism 110.

[0084] Furthermore, the curved rib 142 needs to be positioned between 1 / 4 and 1 / 3 of the width of the conveyor belt 116. If the curved rib 142 is positioned too close to the edge, a corner of the cell may not contact the curved rib 142, preventing the cell from turning. If the curved rib 142 is positioned too close to the center, it may block the cell from moving forward in the conveying direction.

[0085] Furthermore, the front end of the curved rib 142 (i.e., the portion that contacts the corner of the cell) is a curved surface structure, while the rear end of the curved rib 142 is a flat surface structure. The curved surface structure ensures that the corner of the cell does not experience excessive impact or jamming when contacting the curved rib 142, thereby smoothly initiating rotation. This provides a smooth transition, reduces friction and damage to the cell during contact, and ensures the integrity and quality of the cell. It can effectively guide the rotation direction of the cell, ensuring that the cell rotates along the predetermined path during transportation, avoiding deviation or jamming. It should be noted that the curvature of the curved surface structure should be moderate to ensure that the cell can gradually and stably rotate 90 degrees after contact. If the curvature is too large, the cell may experience excessive deviation or jamming upon contact; if the curvature is too small, the cell may not be able to smoothly initiate rotation.

[0086] Preferably, the automatic horizontal and vertical splitting device 10 also includes two first blocking mechanisms 150, one of which is arranged before the first splitting mechanism 120, and the other is arranged between the turning mechanism 140 and the second splitting mechanism 130. The first blocking mechanism 150 includes a fourth support seat, a third driving member 152, a third connecting member and a first vertical baffle 154. The fourth support seat is arranged on the conveying mechanism 110, and the third driving member 152 is arranged on the fourth support seat. The top of the third connecting member is connected to the third driving member 152, and the bottom of the third connecting member is connected to the first vertical baffle 154; wherein, the third driving member 152 drives the first vertical baffle 154 to descend or rise through the third connecting member to block the battery cell or allow it to continue to be transported.

[0087] Specifically, if Figure 7As shown, the fourth support base is composed of two fourth fixing plates 1511 and a fourth connecting plate 1512. The two fourth fixing plates 1511 are vertically disposed on either side of the conveyor belt support plate 1161, and the ends of the fourth connecting plate 1512 are connected to the two fourth fixing plates 1511. The third driving member 152 is disposed in the center of the top surface of the fourth connecting plate 1512. The bottom of the third driving member 152 passes through the fourth connecting plate 1512 and is connected to the first vertical baffle connecting plate 1541. One side of the first vertical baffle connecting plate 1541 is connected to the first vertical baffle 154. Two vertically movable first guide posts 153 are also vertically disposed on either side of the third driving member 152. The bottom of the first guide posts 153 is connected to the first vertical baffle connecting plate 1541. Both first guide posts 153 are sleeved with first bushings 1531. The coordinated use of first guide post 153 and first bushing 1531 ensures the accuracy of the vertical movement of first vertical baffle connecting plate 1541, thereby ensuring the accuracy and reliability of first blocking mechanism 150 in blocking and guiding materials. The primary function of first blocking mechanism 150 is to block and guide materials, while also serving as a material discharge and blocking mechanism when materials are needed in the next process.

[0088] Preferably, the first blocking mechanism 150 further includes a third detection switch 155, which is disposed on the fourth support base and is used to detect whether a battery cell is blocked by the first vertical baffle 154. Specifically, the third detection switch 155 is fixed to the fourth connecting plate 1512 via a third detection switch fixing plate 1551. When the third detection switch 155 detects the entry of a battery cell, the third driving member 152 drives the first vertical baffle 154 downward to block and guide the material. When the third detection switch 155 detects the material, and the next process requires the material, the third driving member 152 drives the first vertical baffle 154 upward to allow the material to flow into the next process.

[0089] It should be noted that if Figure 2 As shown, a vertical support bracket can also be provided on the conveyor belt support plate 1161 at the end of the conveying mechanism 110 of the present invention (i.e., after the second splitting mechanism 130) to facilitate the subsequent installation of the pushing mechanism 160 and the second blocking mechanism 180.

[0090] It should be noted that if Figure 1 As shown, the automatic transverse and longitudinal splitting device 10 of the present invention includes at least one pushing mechanism 160, a transfer platform 170 and a second blocking mechanism 180. The numbers of the three are corresponding and the specific number can be adjusted according to the actual production situation. In this embodiment, two of each mechanism are used as an example.

[0091] Preferably, the automatic transverse and longitudinal splitting device 10 further includes at least one pushing mechanism 160, which is arranged behind the second splitting mechanism 130. The pushing mechanism 160 includes a fifth support seat, a fifth driving member 162, a screw rod 163, a movable seat 164, a sixth driving member 165 and a flip push plate 166. The fifth support seat is arranged on the conveying mechanism 110, the screw rod 163 is arranged in the fifth support seat, the fifth driving member 162 is arranged at one end of the screw rod 163, and the movable seat 164 is provided with a sixth driving member 165. The top of the seat 164 is sleeved on the screw rod 163, the sixth driving member 165 is arranged at the bottom of the movable seat 164, and the flip push plate 166 is hinged to the sixth driving member 165; wherein, when the battery cell enters the pushing mechanism 160, the sixth driving member 165 drives the flip push plate 166 to press down to close to the surface of the conveying mechanism 110, and the fifth driving member 162 drives the movable seat 164 to move along the length direction of the screw rod 163, so that the flip push plate 166 pushes the battery cell to the transfer platform 170.

[0092] Specifically, if Figure 8 As shown, the fifth support base is composed of two fifth fixing plates 1611 and a fifth connecting plate 1612. The ends of the fifth connecting plate 1612 are respectively connected to the two fifth fixing plates 1611, and the top of the fifth connecting plate 1612 is fixedly connected to the vertical support bracket. A screw rod 163 is disposed between the two fifth fixing plates 1611, and one end of the screw rod 163 extends out of the fifth fixing plate 1611 and connects to the fifth driving member 162. The top of the movable seat 164 is sleeved on the screw rod 163, and the bottom of the movable seat 164 is connected to the sixth driving member 165. A side plate 1641 is provided on both sides of the bottom of the movable seat 164, and a sixth driving member connecting plate 1653 is provided on the inner side of the middle part of the two side plates 1641. Two sixth driving member fixing seats 1651 are provided on the sixth driving member connecting plate 1653 at intervals. The top of the sixth driving member fixing seat 1651 is provided with a sixth driving member rotating shaft 1652. The middle part of the sixth driving member 165 is rotatably connected to the sixth driving member rotating shaft 1652, and the rear end of the sixth driving member 165 is movably connected to the movable seat 164 up and down. A flip push plate rotating seat 1661 is provided on the inner front end of each of the two side panels 1641, each connected by a flip push plate rotating shaft 1662. A flip push plate connecting plate 1663 is provided between the two flip push plate rotating seats 1661. A retaining groove is provided at the front end of each of the two side panels 1641, matching the bottom of the flip push plate connecting plate 1663. A hinge seat is provided on the flip push plate connecting plate 1663. The sixth driving member 165 is hingedly connected to the flip push plate connecting plate 1663 via a hinge 1664 and a pin of the hinge seat. A flip push plate 166 is provided on the outer side of the flip push plate connecting plate 1663. Two second guide posts 1665 are provided between the flip push plate connecting plate 1663 and the flip push plate 166. Both second guide posts 1665 are sleeved with a second bushing 1666 and a first elastic member 1667.

[0093] When the conveyor belt 116 delivers the battery cell with completed horizontal and vertical splitting to the position of the pushing mechanism 160, the piston rod of the sixth driving member 165 extends to the front end, and the rear end of the sixth driving member 165 is slightly lifted. The piston rod pushes the hinge 1664 to drive the flip push plate connecting plate 1663 to rotate downward around the flip push plate rotation axis 1662 until its bottom abuts against the limit groove. At the same time, the flip push plate connecting plate 1663 drives the flip push plate 166 to press down around the flip push plate rotation axis 1662, The bottom is close to the surface of the conveyor belt 116, and the fifth driving member 162 drives the movable seat 164 to move forward, driving the flip push plate 166 to move, and pushing the battery cell to the transfer platform 170. After pushing is completed, the sixth driving member 165 drives the flip push plate 166 to lift up, and the fifth driving member 162 drives the movable seat 164 to retreat, driving the flip push plate 166 to retreat. In this way, because the flip push plate 166 is in a raised state, its retreat will not affect the continued transportation of other battery cells on the conveyor belt 116.

[0094] It should be noted that the pushing direction of the pushing mechanism 160 is perpendicular to the conveying direction of the battery cells. The function of the pushing mechanism 160 is to push the battery cells onto the transfer platform 170 on the side of the conveying mechanism 110 .

[0095] Preferably, the automatic transverse and longitudinal splitting device 10 also includes at least one transfer platform 170, which corresponds to the pushing mechanism 160 and is arranged on the side of the conveying mechanism 110. The transfer platform 170 includes a sixth support seat 171, a longitudinal baffle 172, a transverse baffle 173, a seventh driving member 175 and a longitudinal movable push plate 176. The sixth support seat 171 is arranged on the side of the conveying mechanism 110, and the longitudinal baffle 172 and the transverse baffle 173 are arranged perpendicular to each other on the sixth support seat 171. The seventh driving member 175 is arranged on the side of the sixth support seat 171, and the longitudinal movable push plate 176 is connected to the seventh driving member 175 and is opposite to the longitudinal baffle 172; wherein, after the pushing mechanism 160 pushes the battery cell to abut against the transverse baffle 173, the seventh driving member 175 drives the longitudinal movable push plate 176 to move toward the longitudinal baffle 172 to push the battery cell until it abuts against the longitudinal baffle 172.

[0096] Specifically, if Figure 9As shown, the longitudinal baffle 172 and the transverse baffle 173 are disposed perpendicularly to each other in the middle of the top surface of the sixth support seat 171. The transverse baffle 173 is parallel to the conveying direction and opposite the pusher mechanism 160. The longitudinal baffle 172 is perpendicular to the conveying direction and disposed at one end of the transverse baffle 173. Together, they form a transfer positioning area. The seventh driving member 175 is disposed on the side of the sixth support seat 171 and opposite the longitudinal baffle 172. The seventh driving member 175 is connected to the longitudinal movable push plate 176 via a longitudinal movable push plate connecting plate 1761 and a longitudinal movable push plate fixing plate 1762, which are disposed in sequence. Two third guide posts 1763 are disposed between the longitudinal movable push plate fixing plate 1762 and the longitudinal movable push plate 176. Both third guide posts 1763 are sleeved with a third bushing 1764 and a second elastic member 1765.

[0097] Specifically, if Figure 10 As shown, below the sixth support seat 171, the tenth driving member 174 is fixedly mounted to the bottom of the longitudinal baffle 172 and the transverse baffle 173 using the tenth driving member fixing plate 1741. Both the longitudinal baffle 172 and the transverse baffle 173 can be moved vertically up and down using the tenth driving member 174. During the production process of battery cells, slight differences in the thickness of battery cells from different batches, or slight changes in the relative position between the transfer platform 170 and other components such as the conveying mechanism 110 during equipment installation, commissioning, and long-term operation may result in the battery cells being pushed to the transfer platform 170 by the pushing mechanism 160. The contact and abutment between the longitudinal baffle 172 and the transverse baffle 173 may not be optimal. By providing the tenth driving member 174, the height position of the longitudinal baffle 172 and the transverse baffle 173 can be flexibly adjusted according to actual conditions. For example, when the thickness of the battery cell is slightly larger than expected, the tenth driving member 174 can be used to drive the longitudinal baffle 172 and the transverse baffle 173 to move upward a certain distance to ensure that the battery cell can smoothly and accurately abut against the baffle, avoiding problems such as the battery cell not being fully in place or getting stuck due to the baffle being too low; conversely, when the thickness of the battery cell is slightly smaller than expected, the height of the baffle can be appropriately lowered to ensure reliable contact between the battery cell and the baffle, thereby improving the accuracy and reliability of the transfer platform 170 in positioning the battery cell, providing more accurate battery cell positions for subsequent production links, and ensuring the smooth progress of the entire production process and the stability of product quality.

[0098] Preferably, the automatic horizontal and vertical splitting device 10 also includes at least one second blocking mechanism 180, which is correspondingly arranged before the pushing mechanism 160. The second blocking mechanism 180 includes a seventh support seat 181, an eighth driving member 182, a fourth connecting member and a second vertical baffle 183. The seventh support seat 181 is arranged on the conveying mechanism 110, and the eighth driving member 182 is arranged on the seventh support seat 181. The top of the fourth connecting member is connected to the eighth driving member 182, and the bottom of the fourth connecting member is connected to the second vertical baffle 183; wherein, the eighth driving member 182 drives the second vertical baffle 183 to descend or rise through the fourth connecting member to block the battery cell or allow it to continue to be transported.

[0099] Specifically, if Figure 11 As shown, the seventh support seat 181 is installed on the vertical support bracket, the eighth driving member 182 is arranged on the seventh support seat 181, the top of the second vertical baffle connecting plate 1831 is connected to the eighth driving member 182, and the bottom of the second vertical baffle connecting plate 1831 is connected to the second vertical baffle 183.

[0100] It should be noted that the second blocking mechanism 180 is preferably used in conjunction with multiple, sequentially installed ones. A single second blocking mechanism 180 primarily serves as a guide. When multiple second blocking mechanisms 180 are installed simultaneously, their coordinated action ensures the proper functioning of the subsequent multiple pushing mechanisms 160 and transfer platform 170, enabling faster cell guiding and unloading operations, reducing waiting and adjustment time, and thus improving the efficiency of the entire production process.

[0101] Preferably, the automatic horizontal and vertical splitting device 10 also includes a positioning mechanism 190, which is arranged between the second blocking mechanism 180 and the second splitting mechanism 130. The positioning mechanism 190 includes two support plates 191, a fixed baffle 192, a ninth driving member 193 and a movable baffle 194. The two support plates 191 are spaced apart and are respectively arranged on both sides of the conveying mechanism 110. The fixed baffle 192 is arranged on the inner side of one of the support plates 191, and the movable baffle 194 is arranged on the inner side of the other support plate 191. The ninth driving member 193 is arranged on the fixed baffle 192 and is connected to the movable baffle 194; wherein, when the battery cell enters the positioning mechanism 190, the ninth driving member 193 drives the movable baffle 194 close to or away from the fixed baffle 192 to clamp or release the battery cell.

[0102] Specifically, if Figure 12As shown, two support plates 191 are respectively arranged on either side of the conveyor belt support plate 1161, and a fixed baffle 192 and a movable baffle 194 are respectively arranged on either side of the conveyor belt 116. The fixed baffle 192 and the movable baffle 194 are both close to the surface of the conveyor belt 116. Two fourth guide posts 195 are arranged between the upper portions of the two support plates 191. A fixed baffle connecting plate 1921 and a movable baffle connecting plate 1941 are respectively provided through the ends of the two fourth guide posts 195. The fixed baffle 192 and the movable baffle 194 are respectively provided on the fixed baffle connecting plate 1921 and the movable baffle connecting plate 1941. A ninth driving member 193 is also provided on the fixed baffle connecting plate 1921. The movable end of the ninth driving member 193 is connected to the movable baffle connecting plate 1941 via a connecting seat 196. Fourth bushings 1951 are also provided at the locations where the two fourth guide posts 195 pass through the movable baffle connecting plate 1941.

[0103] Preferably, the automatic horizontal and vertical splitting device 10 also includes an anti-drop mechanism 200, which is arranged at the end of the conveying mechanism 110. The anti-drop mechanism 200 includes an eighth support seat and an anti-drop baffle 202. The eighth support seat is arranged on the conveying mechanism 110, and the anti-drop baffle 202 is connected to the eighth support seat and is close to the surface of the conveying mechanism 110.

[0104] Specifically, if Figure 13 As shown, the eighth support base is composed of two eighth fixing plates 2011 and an eighth connecting plate 2012. The two eighth fixing plates 2011 are respectively vertically arranged on both sides of the conveyor belt support plate 1161, and the ends of the eighth connecting plate 2012 are respectively connected to the two eighth fixing plates 2011. The main function of the anti-drop mechanism 200 is to prevent the conveyor belt 116 from conveying the battery cells to the end. If the pushing mechanism 160 fails to push the battery cells away in time, the anti-drop mechanism 200 will block the battery cells and prevent them from falling.

[0105] In this embodiment, the first driving member 122, the third driving member 152, the fourth driving member 112, the fifth driving member 162, the sixth driving member 165, the seventh driving member 175, the eighth driving member 182, the ninth driving member 193, and the tenth driving member 174 are all cylinders, but are not limited to this. In other embodiments, they can also be hydraulic cylinders or electric cylinders, etc., which are not specifically limited in the present invention.

[0106] In this embodiment, the first elastic member 1667 and the second elastic member 1765 are both springs, but are not limited thereto. In other embodiments, they may also be elastic retaining rings or rubber rings, etc., which are not specifically limited in the present invention.

[0107] The present invention also provides a method for automatically splitting a flexible module battery sheet horizontally and vertically, which is applied to an automatic horizontal and vertical splitting device for a flexible module battery sheet, specifically comprising:

[0108] S101, transporting the battery cells sequentially through the first splitting mechanism 120 and the second splitting mechanism 130 by the conveying mechanism 110;

[0109] Specifically, the cell includes a protective layer, an adhesive, and a silicon wafer stacked in sequence. Both the protective layer and the silicon wafer are provided with aligned scratches to facilitate breaking between multiple small pieces, improving the efficiency of small piece preparation. There are multiple scratches, each of which includes multiple first scratches and multiple second scratches. The multiple first scratches are arranged in parallel and at equal intervals, and the multiple second scratches are arranged in parallel and at equal intervals. The first scratches are perpendicular to the second scratches. The multiple first scratches and the multiple second scratches work together to form a grid-like stress notch on the flexible cell, facilitating breaking into small pieces.

[0110] S102, using the first splitting mechanism 120 to break the protective layer and the silicon wafer along the scratch from a first direction to split the solar cell into multiple strips connected by adhesive;

[0111] Specifically, before entering the first splitting mechanism 120 , the material is also guided by the first blocking mechanism 150 , while controlling the discharge and blocking of the battery cells.

[0112] Furthermore, when the first splitting mechanism 120 detects the entry of the battery cell, the first driving member 122 drives the first rolling wheel 124 to rise, and the first rolling wheel 124 abuts against the bottom surface of the conveyor belt 116 so that the top surface of the conveyor belt 116 protrudes to form an angle.

[0115] Specifically, before entering the second splitting mechanism 130 , the battery cell is first gradually rotated 90 degrees during transportation by the turning mechanism 140 , and then the material is guided and transported in a controlled manner by the first blocking mechanism 150 .

[0116] Furthermore, the splitting process of the second splitting mechanism 130 is the same as that of the first splitting mechanism 120, except for the splitting direction, which will not be described in detail here.

[0118] S104 , after the battery cells leave the second splitting mechanism 130 , the alignment mechanism 190 aligns the battery cells to ensure that the positions of the battery cells entering the pushing mechanism 160 are uniform, facilitating accurate pushing.

[0119] S105 , the second blocking mechanism 180 is used to control the material to be guided and the discharge and blocking of the battery cells are controlled at the same time.

[0120] S106 , the battery cells are pushed into the transfer platform 170 through the pushing mechanism 160 , and the transfer platform 170 positions the battery cells in the horizontal and vertical directions, and notifies the downstream equipment robot to pick up the cells.

[0121] This invention overcomes the limitations of traditional wafer splitting methods, precisely cleaving the protective layer and silicon wafer within the three-layer structure of a cell without damaging the adhesive, ensuring that the cell remains bonded after splitting. This not only provides a strong guarantee for all subsequent production steps, including splitting, shaping, and laminating, but also significantly improves production efficiency and product quality.

[0122] Furthermore, the method of the present invention realizes fully automatic production, reduces manual operation links, reduces labor costs and error rates, greatly improves production efficiency, and makes the preparation process of battery cells more efficient and stable.
