DETAILED DESCRIPTION

[0027] In the present invention, unless otherwise specified, directional words such as "upper, lower, left, right" are generally understood in conjunction with the directions shown in the drawings and actual applications.

[0028] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0029] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0030] The endpoints and any values ​​of the ranges 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 endpoint values ​​of each range, the endpoint values ​​of each range and the individual point values, and the individual point values ​​can be combined with each other to obtain one or more new numerical ranges, which should be considered as specifically disclosed in this article. Among them, the terms "optional" and "optional" all mean that they may be included or not included (or may be present or not).

[0031] The flexible battery sheet involved in the embodiment of the present invention is arranged in a rectangular shape, and the battery sheet includes a protective layer, an adhesive and a silicon sheet stacked in sequence, and the protective layer and the silicon sheet are provided with scratches aligned with each other to facilitate the subsequent breaking between multiple small sheets and improve the efficiency of small sheet preparation. Among them, the protective layer can be made of materials such as glass or resin, and the present invention does not limit it.

[0032] It should be noted that before the battery cell enters the splitting process, laser or diamond scribing is required to form aligned scratches on the protective layer and the silicon wafer.

[0033] 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-like stress notch on the flexible battery sheet, which is convenient for cutting into small pieces.

[0034] The embodiment of the present invention provides an automatic horizontal and vertical splitting device 10, which is used to split the protective layer and silicon wafer in the three-layer structure of the battery cell without splitting the adhesive in the middle, so that the battery cell after the splitting is still in an adhesive state. At this time, the battery cell is in a semi-broken state as a whole (i.e., seemingly broken but not broken), which can maintain the integrity of the battery cell without being scattered into small particles, thereby facilitating the circulation of the battery cell and providing conditions for subsequent all-round breaking, shaping, and extended-distance laminating production. The present invention has a high degree of automation and can effectively improve production capacity and product quality.

[0035] The following will explain in detail why the present invention needs to split the protective layer and the silicon wafer, but not split the adhesive in the middle: The back-contact flexible component battery is a solar cell. In the production process of the back-contact flexible component battery, the cell sheet needs to be split into multiple small pieces first, and then a preset number of small pieces are bonded to the flexible circuit board, with a certain gap between adjacent small pieces, to form a back-contact flexible component battery. In this way, when the back-contact flexible component battery needs to be used, the flexible circuit board is unfolded to achieve the flattening of multiple small pieces, so as to increase the contact area between the small pieces and the sunlight, thereby realizing the photovoltaic power generation function of the back-contact flexible component battery and ensuring the power generation efficiency; when the back-contact flexible component battery is not needed, the flexible circuit board is rolled up for easy storage and saves space. In 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, which is convenient for the storage of the back-contact flexible component battery.

[0036] Based on the above situation, splitting the battery cell into multiple small pieces is an important process for realizing flexible batteries, and the existing technology adopts a one-time splitting process, which specifically has two points to be improved. First, the splitting process requires a large pressure to completely split a large battery cell into small battery cells at one time, which can easily cause the battery cell to be crushed and produce defects. Second, splitting the battery cell into small pieces at one time is not convenient for the subsequent process of the battery cell.

[0037] In order to solve the technical problems existing in the primary splitting process, the inventor 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 secondary splitting process can significantly reduce the pressure required in the splitting process, avoiding defects caused by cell fracturing 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.

[0038] 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 a flexible component battery sheet, the automatic horizontal and vertical splitting device 10 comprises a frame 100, a conveying mechanism 110, a first splitting mechanism 120 and a second splitting mechanism 130, the conveying mechanism 110 is arranged on the frame 100, the first splitting mechanism 120 and the second splitting mechanism 130 are sequentially arranged on the conveying mechanism 110 along the conveying direction of the conveying mechanism 110, the conveying mechanism 110 is used to transport the battery sheet along the conveying direction, the first splitting mechanism 120 is used to break the protective layer and the silicon wafer along the scratch from the first direction so that the battery sheet is split into a plurality of strips connected by adhesive, the second splitting mechanism 130 is used to break the protective layer and the silicon wafer along the scratch from the second direction so that the plurality of battery sheets are split into a plurality of small battery sheets connected by adhesive, wherein the first direction and the second direction are perpendicular to each other. The present invention realizes fully automated production without manual intervention, and has the advantages of reducing costs, improving product quality and improving production efficiency.

[0039] 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.

[0040] Preferably, the conveying mechanism 110 includes a fixed seat 111, a fourth driving member 112, a driving wheel 115, a conveying belt 116 and a driven wheel 117.

One end of the fourth driving member 112 is connected to a synchronous wheel 113, and the synchronous wheel 113 is connected to another synchronous wheel 113 through a synchronous belt 114. The other synchronous wheel 113 drives the driving wheel 115 to rotate. The driving wheel 115 is connected to the driven wheel 117 through the conveyor belt 116. A tensioning wheel 118 is also arranged in the middle of the conveyor belt 116. Among them, the driving wheel 115 is fixed to the conveying belt support plate 1161 through the driving wheel fixing plate 1151, the driven wheel 117 is fixed to the conveying belt support plate 1161 through the driven wheel fixing plate 1171, and the tensioning wheel 118 is fixed to the conveying belt support plate 1161 through the tensioning wheel fixing plate 1181.

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.

The bottom of the first driving member 122 is the 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. The two ends of the first rolling wheel fixing plate 1232 are respectively located in the gaps between the two 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". The two 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 inside the conveyor belt support plate 1161. The first idler wheel support plate 1271 has through grooves that match 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. The tops of the two first idler wheels 127 are in contact with the conveyor belt 116.

[0045] Among them, the two bottoms of the first rolling wheel fixing plate 1232 need to be arranged in the gaps between the two 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 in contact with 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 inside the conveyor belt support plate 1161, but the preferred arrangement of 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 in natural contact with the conveyor belt 116, which can assist in transmission and guiding, ensure the stable operation of the belt, and reduce wear.

[0046] It should be noted that as Figure 5As shown, the first follower belt 125 is disposed 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 larger than 1 mm, and more preferably, the width of the gap is 2 mm-10 mm. 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 failure 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 failure to play a good pressing role, thereby affecting the splitting effect, and may even cause some scratches to not be broken.

[0047] Furthermore, 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, and 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.

[0048] Preferably, the first splitting mechanism 120 further includes two first detection switches 128, which are respectively disposed at the two ends of the first follower belt 125, and are respectively used to detect that the battery cell enters and leaves the first splitting mechanism 120. Specifically, the two first detection switches 128 are respectively disposed at the two ends of the first follower belt 125 through two first detection switch fixing plates 1281, and when the battery cell is detected to enter, the first driving member 122 drives the first rolling wheel 124 to rise through the first connecting member, and when the battery cell is detected to leave completely, the first driving member 122 drives the first rolling wheel 124 to descend through the first connecting member.

[0049] 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 so that the multiple battery cells are split into multiple small battery cells connected to each other by adhesive.

[0050] Preferably, the second splitting mechanism 130 further includes two second detection switches, which are respectively arranged at two ends of the second follower belt and are respectively used to detect the battery cells entering and leaving the second splitting mechanism 130 .

[0051] In this embodiment, the specific structure of the second splitting mechanism 130 is the same as the specific structure of the first splitting mechanism 120, except that the splitting directions are different, which will not be described again.

[0052] Preferably, the automatic transverse and longitudinal 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, 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.

[0053] Specifically, Figure 6 As shown, the third support seat is composed of two third fixing plates 1411 and a third connecting plate 1412. The two third fixing plates 1411 are respectively 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 inner side surface of the top 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.

[0054] Furthermore, the arcuate rib 142 needs to be located at 1 / 4 to 1 / 3 of the width of the entire conveyor belt 116. If the arcuate rib 142 is located too close to the edge, a corner of the cell may not be able to abut against the arcuate rib 142, thereby causing the cell to be unable to turn. If the arcuate rib 142 is located too close to the center, it may block the cell from moving forward in the conveying direction.

[0055] Furthermore, the front end of the arcuate rib 142 (i.e., the portion abutting against the corner of the battery cell) is an arcuate structure, and the rear end of the arcuate rib 142 is a planar structure. The arcuate structure can ensure that the corner of the battery cell will not produce excessive impact or jamming when contacting the arcuate rib 142, so that the battery cell can start to rotate smoothly, and can provide a smooth transition, reduce the friction and damage of the battery cell during contact, ensure the integrity and quality of the battery cell, and effectively guide the rotation direction of the battery cell to ensure that the battery cell rotates along the predetermined path during transportation to avoid deviation or jamming. It should be noted that the curvature of the arcuate structure should be moderate to ensure that the battery cell can gradually and stably rotate 90 degrees after contact. If the curvature is too large, the battery cell may produce excessive deviation or jamming when in contact; if the curvature is too small, the battery cell may not start to rotate smoothly.

[0056] Preferably, the automatic transverse and longitudinal 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, 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 ascend through the third connecting member to block the battery cell or allow it to continue to be transported.

[0057] Specifically, Figure 7As shown, the fourth support seat is composed of two fourth fixing plates 1511 and a fourth connecting plate 1512. The two fourth fixing plates 1511 are respectively vertically arranged on both sides of the conveyor belt support plate 1161, and the two ends of the fourth connecting plate 1512 are respectively connected to the two fourth fixing plates 1511. The third driving member 152 is arranged in the middle 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. The fourth connecting plate 1512 is also vertically provided with two first guide pillars 153 that can move up and down on both sides of the third driving member 152. The bottom of the first guide pillar 153 is connected to the first vertical baffle connecting plate 1541, and the two first guide pillars 153 are both sleeved with first bushings 1531. The first guide column 153 and the first bushing 1531 can ensure the movement accuracy of the first vertical baffle connecting plate 1541 when it moves up and down, thereby ensuring the accuracy and reliability of the first blocking mechanism 150 when blocking the material for correction. The main function of the first blocking mechanism 150 is to block the material for correction, and at the same time, it can be used as a material discharge and blocking function when the next process needs the material.

[0058] Preferably, the first blocking mechanism 150 further includes a third detection switch 155, which is disposed on the fourth support seat and is used to detect whether any battery cell is blocked by the first vertical baffle 154. Specifically, the third detection switch 155 is fixed to the fourth connecting plate 1512 through the third detection switch fixing plate 1551. When the third detection switch 155 detects that a battery cell enters, the third driving member 152 drives the first vertical baffle 154 to descend to block and guide the material. When the third detection switch 155 detects the material, when the next process needs the material, the third driving member 152 drives the first vertical baffle 154 to ascend, and the material flows into the next process.

[0059] It should be noted that if Figure 2 As shown, a vertical support bracket may also be provided on the conveyor belt support plate 1161 at the end of the conveyor mechanism 110 of the present invention (i.e. after the second splitting mechanism 130) to facilitate the installation of the subsequent pushing mechanism 160 and the second blocking mechanism 180.

[0060] 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 consistent, and the specific number can be adjusted according to actual production conditions. In this embodiment, two of each mechanism are used as an example.

[0061] 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 arranged on the conveying mechanism 110. 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 be 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.

[0062] Specifically, Figure 8 As shown, the fifth support seat is composed of two fifth fixing plates 1611 and a fifth connecting plate 1612. The two 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. The screw rod 163 is arranged between the two fifth fixing plates 1611, and one end of the screw rod 163 extends out of the fifth fixing plate 1611 and is connected 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 respectively arranged on both sides of the bottom of the movable seat 164, and a sixth driving member connecting plate 1653 is arranged on the inner side of the middle part of the two side plates 1641. Two sixth driving member fixing seats 1651 are arranged 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. The inner sides of the front ends of the two side plates 1641 are each provided with a flip push plate rotating seat 1661 through 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, the front ends of the two side plates 1641 are provided with a limit groove matching the bottom of the flip push plate connecting plate 1663, a hinge seat is provided on the flip push plate connecting plate 1663, and the sixth driving member 165 is hingedly connected to the flip push plate connecting plate 1663 through the hinge 1664 and the 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 pillars 1665 are provided between the flip push plate connecting plate 1663 and the flip push plate 166, and the two second guide pillars 1665 are both sleeved with a second bushing 1666 and a first elastic member 1667.

[0063] When the conveyor belt 116 delivers the battery cell with completed transverse and longitudinal 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, and the piston rod pushes the hinge 1664 to drive the flip push plate connecting plate 1663 to rotate downward around the flip push plate rotating shaft 1662 until its bottom abuts against the limit groove, and the flip push plate connecting plate 1663 simultaneously drives the flip push plate 166 to press down around the flip push plate rotating shaft 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 pushes the battery cell to the transfer platform 170. After pushing the material, 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 lifted state, its retreat will not affect the continued transportation of other battery cells on the conveyor belt 116.

[0064] It should be noted that the pushing direction of the pushing mechanism 160 is perpendicular to the conveying direction of the battery cells, and 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 .

[0065] 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, 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 until it abuts 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.

[0066] Specifically, Fig. 9As shown, the longitudinal baffle 172 and the transverse baffle 173 are mutually perpendicularly arranged at the middle position of the top surface of the sixth support seat 171, the transverse baffle 173 is parallel to the conveying direction and opposite to the material pushing mechanism 160, and the longitudinal baffle 172 is perpendicular to the conveying direction and arranged at one end of the transverse baffle 173, and the two together form a transfer positioning area. The seventh driving member 175 is arranged on the side of the sixth support seat 171 and opposite to the longitudinal baffle 172. The seventh driving member 175 is connected to the longitudinal movable push plate 176 through the longitudinal movable push plate connecting plate 1761 and the longitudinal movable push plate fixing plate 1762 arranged in sequence. Two third guide pillars 1763 are arranged between the longitudinal movable push plate fixing plate 1762 and the longitudinal movable push plate 176, and the two third guide pillars 1763 are both sleeved with a third bushing 1764 and a second elastic member 1765.

[0067] Specifically, Fig.10 As shown, below the sixth support seat 171, the tenth driving member 174 is fixedly installed on the bottom of the longitudinal baffle 172 and the transverse baffle 173 by the tenth driving member fixing plate 1741. Both the longitudinal baffle 172 and the transverse baffle 173 can be moved up and down in the vertical direction by the tenth driving member 174. In the production process of battery cells, there may be slight differences in the thickness of battery cells in 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, resulting in the battery cells being pushed to the transfer platform 170 by the pushing mechanism 160. The contact and abutment with the longitudinal baffle 172 and the transverse baffle 173 are not in the optimal state. By setting 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, thereby avoiding problems such as the battery cell not being able to fully fall into 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 precise battery cell positions for subsequent production links, and ensuring the smooth progress of the entire production process and the stability of product quality.

[0068] Preferably, the automatic transverse and longitudinal 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.

[0069] Specifically, Fig.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.

[0070] It should be noted that the second blocking mechanism 180 is preferably used together with a plurality of second blocking mechanisms 180 arranged in sequence. If there is a single second blocking mechanism 180, it mainly plays a guiding role. When multiple second blocking mechanisms 180 are installed at the same time, the synergistic effect of the multiple subsequent pushing mechanisms 160 and the transfer platform 170 can ensure that the subsequent multiple pushing mechanisms 160 and the transfer platform 170 can operate normally, and the guiding and unloading operations of the battery cells can be completed more quickly, reducing the waiting time and adjustment time, thereby improving the efficiency of the entire production process.

[0071] Preferably, the automatic transverse and longitudinal 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 to approach or move away from the fixed baffle 192 to clamp or release the battery cell.

[0072] Specifically, Fig.12As shown, two support plates 191 are respectively arranged on both sides of the conveyor belt support plate 1161, a fixed baffle 192 and a movable baffle 194 are respectively arranged on both sides of the conveyor belt 116, and the fixed baffle 192 and the movable baffle 194 are both close to the surface of the conveyor belt 116. Two fourth guide pillars 195 are arranged between the upper parts of the two support plates 191, and a fixed baffle connecting plate 1921 and a movable baffle connecting plate 1941 are respectively penetrated on both ends of the two fourth guide pillars 195, and the fixed baffle 192 and the movable baffle 194 are respectively arranged on the fixed baffle connecting plate 1921 and the movable baffle connecting plate 1941. A ninth driving member 193 is also arranged on the fixed baffle connecting plate 1921, and the movable end of the ninth driving member 193 is connected to the movable baffle connecting plate 1941 through a connecting seat 196, and a fourth bushing 1951 is also arranged at the position where the two fourth guide pillars 195 pass through the movable baffle connecting plate 1941.

[0073] Preferably, the automatic transverse and longitudinal 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.

[0074] Specifically, Fig.13 As shown, the eighth support seat 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 two 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 cell to the end. When the pushing mechanism 160 fails to push the battery cell away in time, the battery cell is blocked to prevent the battery cell from falling.

[0075] 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 may also be hydraulic cylinders or electric cylinders, etc., and the present invention does not make specific limitations.

[0076] 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.

[0077] The present invention also provides a method for automatically splitting a flexible component battery sheet horizontally and vertically, which is applied to an automatic horizontal and vertical splitting device for a flexible component battery sheet, and specifically includes: S101, transporting the battery cells in sequence through the first splitting mechanism 120 and the second splitting mechanism 130 by the conveying mechanism 110; Specifically, the battery cell includes a protective layer, an adhesive and a silicon wafer which are stacked in sequence, and the protective layer and the silicon wafer are provided with scratches aligned with each other to facilitate the splitting of multiple small pieces and improve the efficiency of preparing small pieces. There are multiple scratches, and the multiple scratches include 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 battery cell, which is convenient for cutting into small pieces.

[0078] S102, using the first splitting mechanism 120 to break the protective layer and the silicon wafer along the scratch from a first direction so as to split the solar cell into a plurality of strips connected by adhesive; Specifically, before entering the first splitting mechanism 120 , the material is also guided by the first blocking mechanism 150 , and the discharge and blocking of the battery cells are controlled at the same time.

[0079] 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 to make the top surface of the conveyor belt 116 protrude to form an angle, and the conveyor belt 116 cooperates with the first follower belt 125 to break 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.

[0080] S103, using the second splitting mechanism 130 to break the protective layer and the silicon wafer along the scratch from a second direction so as to split the plurality of battery cells into a plurality of small battery cells connected to each other by adhesive; The first direction and the second direction are perpendicular to each other.

[0081] Specifically, before entering the second splitting mechanism 130 , the battery sheet 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 .

[0082] 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 herein.
