Description

Technical Field

[0001] The present invention relates to the technical field of laser cell slice separation, and in particular to a cell slice slice sliding device and method. Background Art

[0002] The technological innovation of cell halving is an inevitable trend in the development of the photovoltaic industry. It not only helps reduce packaging losses, optimize process issues in the module production process, and improve module reliability, but also helps reduce manufacturing costs. Of course, this technology also brings some new challenges and problems, requiring continuous optimization and improvement by companies and researchers within the industry.

[0003] For example, the disclosure (announcement) No. CN113066760A discloses a slicing method and device for cutting a whole battery cell into multiple small battery cells, which is used to slicing a battery cell into n small battery cells. The specific steps are as follows: a scanning laser is used to etch a small groove at both ends of each splitting line of the battery cell to be sliced, and then n-1 splitting devices are used to act on the n-1 splitting lines respectively to slicing the battery cell into n small battery cells.

[0004] The above technical solution has the following defects: the above-mentioned suction cup is used to fix the battery cell, and its operation is cumbersome for the battery cell adsorption process. When the battery cell is cut, the vibration generated may cause the battery cell to separate from the suction cup, resulting in the battery cell position offset, and then causing the laser cutting to have a deviation, which causes the battery cell to be cut into defective products. The above-mentioned suction cup is set in a small number, resulting in a small adsorption area for the battery cell, and the adsorption force of the battery cell cannot be detected at any time. At the same time, the above-mentioned method of driving the battery cell forward is to use a motor to drive the screw to rotate, and the screw drives the suction cup and the battery cell forward. However, after the battery cell is cut, the suction cup needs to return to the initial position, and the motor needs to drive the screw to flip, and then ensure that the suction cup returns to its position. In order to quickly cut the battery cell, this process ensures that the battery cell moves forward at a uniform speed. Once the battery cell is cut and passes the laser generator, the reverse motor is used to run and drive the suction cup back at a uniform speed, which wastes time and reduces work efficiency.

[0014] A method for separating and sliding a battery cell comprises the following steps:

[0015] S1: According to the number and size of cell cuts, the corresponding laser generators are pre-activated. If the cell is cut into two pieces, the middle set of laser generators is activated; if the cell is cut into three pieces, the two sets of laser generators on both sides are activated; if the cell is cut into four pieces, the three sets of laser generators are activated;

[0016] S2: The battery cells are transferred to the tray assembly via the transfer roller. The vacuum negative pressure pump is used to operate the inner ring of the nozzle to form a negative pressure suction force, which can adsorb and lock the battery cells. The air pressure sensor in the inner ring of the nozzle can constantly detect the negative pressure suction force of each nozzle inner ring to prevent excessive suction force from causing battery cell breakage and insufficient pressure from causing battery cell movement.

[0017] S3: By driving the double-sided rack to slide back and forth, the tray assembly can be driven to slide back and forth. When the tray assembly is driven to slide forward, the battery cells on it are cut by the laser beam emitted by the laser generator;

[0018] S4: A row of laser generators at the front pre-cuts a groove on the surface of the cell, and then the air jet assembly at the front sprays cold air on the surface of the cell to cool it down. Then, a row of laser generators at the rear cuts again based on the groove, and the air jet assembly at the rear sprays cold air on the surface of the cell again. The alternating hot and cold air allows the cell to automatically split along the cut groove.

[0019] S5: When the tray assembly passes over the laser generator, the robotic arm behind it takes away the cut battery cells and enters the next process.

[0020] Compared with the prior art, the present invention provides a cell slice sliding device and method, which has the following features:

[0021] Beneficial effects:

[0022] 1. The battery cell slicing slide device and method uses a tool to insert into the notches at both ends of the pallet, and tilt the pallet. At the same time, the clamp is squeezed back into the installation groove by force. The clamp no longer interferes with the cross bar, and the U-shaped frame will also leave the cross bar. Then the entire pallet is removed. By rotating the threaded sleeve on the top of the tee joint, the tee joint and the inner ring of the nozzle can be disengaged. Then, by rotating the locking nut, the restriction on the inner ring of the nozzle can be released. Then, the inner ring of the nozzle can be removed from the rubber outer ring, thereby achieving the purpose of disassembling and repairing the damaged inner ring of the nozzle.

[0023] 2. The battery cell slicing sliding device and method are configured with an upper air pressure sensor inside the inner ring of the nozzle. Once the inner ring of the nozzle and the battery cell form a closed cavity, a negative pressure adsorption force is formed in the cavity. The air pressure sensor can detect the air pressure value in the cavity, and the air pressure value can be directly viewed through an external display screen, thereby detecting the adsorption force of the battery cell.

[0024] 3. The battery cell slicing slide device and method, the battery cells enter the tray assembly through the transfer roller, there are multiple suction nozzle inner rings on the surface of the tray assembly, the vacuum negative pressure pump inside the cabinet is started, the vacuum negative pressure pump's exhaust end is interconnected with the hose, air pipe and three-way joint, the vacuum negative pressure pump exhaust end exhausts air, and the suction nozzle inner ring generates suction, which can negatively adsorb the battery cells that fall on the top of the suction nozzle inner ring, and there is an air pressure sensor in the suction nozzle inner ring. Once the battery cell is sucked, there is no gas flow in the cavity inside the suction nozzle inner ring, and the air pressure sensor will detect the air pressure value in the cavity, thereby realizing negative pressure adsorption of the battery cell. Compared with the traditional suction cup, the negative pressure suction of the present application is adjustable, the adsorption area is large, and its adsorption force is also greater than the adsorption force of the suction cup, thereby ensuring that the battery cell is firmly adsorbed and the battery cell position will not be shifted due to vibration.

[0025] 4. The battery cell slicing sliding device and method drive the servo motor to rotate the driving gear, the driving gear drives the transmission gears on both sides to rotate, and the transmission gear drives the fan gear to rotate synchronously, one of the fan gears drives the double-sided rack to slide forward, and when the tail end of the fan gear disengages from one side of the double-sided rack, the other fan gear continues to engage with the other side of the double-sided rack, and then the double-sided rack will slide back, so that the double-sided rack will perform a forward-backward-forward reciprocating mode, and then the tray assembly will also perform a reciprocating mode. Compared with the traditional operation that requires the motor to reverse and return, the driving servo motor in this application only needs to rotate continuously to move the tray assembly forward and backward without any delay or jamming in the middle, and then it can also ensure that the tray assembly moves forward at a uniform speed during the forward movement and quickly retreats during the backward movement. At the same time, it is linked with the jet assembly. When the tray assembly moves forward, the jet assembly sprays cold air. When the tray assembly moves backward, the jet assembly does not spray cold air, saving the use of cold air. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0052] Example 1: Please refer to Figure 1The cell slicing slide device includes a cabinet 10, a platform plate 20 is fixedly installed on the top of the cabinet 10, and two lifting assemblies 30 are fixedly installed on the top of the cabinet 10 for controlling the horizontal height adjustment; a transverse movement assembly 40 is movably installed between the two lifting assemblies 30 for adjusting the horizontal spacing; three groups of equally spaced laser generators 50 are detachably installed on the bottom of the transverse movement assembly 40, the front row of laser generators 50 pre-cut grooves, and the rear row of laser generators 50 cuts again; the front and back sides of the lifting assembly 30 are fixedly installed with jet assemblies 60 for quickly cooling the cutting seam and cleaning cutting residues.

[0053] See also Figure 1 One end of the surface of the platform plate 20 is equipped with multiple transfer rollers 70 arranged at equal intervals for conducting the battery cells; the other end of the surface of the platform plate 20 is fixedly equipped with a robotic arm 80 for transporting the cut battery cells; a tray assembly 90 is slidingly provided on the surface of the platform plate 20 for adsorbing and fixing the battery cells; a reciprocating drive assembly 100 is provided between the bottom of the platform plate 20 and the cabinet 10 for driving the battery cells forward; a through hole 110 is opened on the surface of the platform plate 20.

[0054] See also Figure 2-3 The lifting assembly 30 includes a vertical shell 31, the bottom of the vertical shell 31 is fixedly mounted on the surface of the platform plate 20, the top of the vertical shell 31 is fixedly mounted with a sealing plate 32, the top of the sealing plate 32 is fixedly mounted with a vertical servo motor 33, the output end of the vertical servo motor 33 is fixedly mounted with a vertical screw rod 34, the bottom of the vertical screw rod 34 is rotatably mounted on the inner bottom wall of the vertical shell 31, and the outer side of the vertical screw rod 34 is threadedly connected with a vertical screw sleeve 35.

[0055] Specifically, the vertical servo motor 33 drives the vertical screw rod 34 to rotate, and the vertical screw rod 34 drives the vertical screw sleeve 35 to move up or down, which can then drive the transverse movement component 40 and the laser generator 50 to move up or down to ensure that the horizontal height position of the laser generator 50 is adjusted.

[0056] See also Figure 3-4The transverse moving assembly 40 includes a transverse shell 41. Both ends of the transverse shell 41 extend into the rectangular holes on the side of the vertical shell 31. The vertical screw sleeves 35 are embedded in the two ends of the transverse shell 41. The inner wall of the vertical shell 31 is fixedly installed with a transverse moving servo motor 42. The output end of the transverse moving servo motor 42 is fixedly installed with a transverse screw rod 43. The other end of the transverse screw rod 43 is rotatably connected to the inner wall of the transverse shell 41. The outer side of the transverse screw rod 43 is provided with two sections of thread grooves with opposite thread directions. The middle section of the outer side of the transverse screw rod 43 is fixedly installed with a limit plate 44. Two symmetrically arranged transverse screw sleeves 45 are threadedly connected to the outside of the screw rod 43, and an extension plate 46 is fixedly installed on the outside of the transverse screw sleeve 45. Both ends of the extension plate 46 extending outward are fixedly installed with a ring plate 47. Three groups of laser generators 50 are all installed on the ring plate 47. The two groups of laser generators 50 on the left and right sides slide on the bottom of the transverse shell 41 through the transverse screw sleeve 45 and the transverse screw rod 43. The laser generator 50 located in the middle group is fixedly installed in the middle part of the bottom of the transverse shell 41 through the extension plate 46 and the ring plate 47.

[0057] Specifically, the transverse screw rod 43 is driven to rotate by the transverse servo motor 42, and the rotating transverse screw rod 43 can control the two transverse screw sleeves 45 to move closer to or separate from each other, and then the laser generators 50 on both sides will move closer to or separate from each other, and the distance between the three groups of laser generators 50 changes, so that the battery cells can be cut into different widths.

[0058] See also Figure 4-5 The jet assembly 60 includes a transverse pipe 61, which is located between the laser generator 50 and the vertical shell 31 and does not contact the laser generator 50. A number of air nozzles 62 are fixedly installed at the bottom of the transverse pipe 61. Both ends of the transverse pipe 61 are fixedly installed on the outer wall of the vertical shell 31 through fasteners 63. One end of the transverse pipe 61 is closed, and an electromagnetic control valve 64 is installed at the other end of the transverse pipe 61. The bottom of the electromagnetic control valve 64 is connected to the exhaust end of the air conditioner, and the air conditioner is installed inside the cabinet 10.

[0059] Specifically, the cold air generated by the air conditioner enters the horizontal pipes 61 on the front and rear sides through the electromagnetic control valve 64, and then the cold air is ejected from the air nozzle 62. When the cold air blows onto the cut battery cells, the cut seams can be cooled and the cutting residues can be blown away. The cut seams of the battery cells can be quickly and naturally cracked in the alternating hot and cold mode. Compared with traditional spraying, the cold air sprayed in this application is cleaner and tidier, and can also reduce the contamination of the battery cells by liquid.

[0060] Based on the first embodiment, the second embodiment is formed: please refer to Figure 6-7The tray assembly 90 includes a base plate 91, which is attached to the platform plate 20. A column 92 is fixedly installed at the bottom of the base plate 91. The column 92 passes through the interior of the through hole 110 and an X-shaped frame 93 is fixedly installed at the bottom. A support frame 94 is installed on the top of the base plate 91. Two symmetrical cross bars 95 are fixedly installed on the inner wall of the support frame 94. A U-shaped frame 96 is set on the outer side of the cross bar 95. A support plate 97 is fixedly installed on the top of the U-shaped frame 96. The surface of the support plate 97 is provided with concave holes arranged at equal intervals, and notches are provided at both ends of the support plate 97.

[0061] Specifically, inserting the tool into the notched slot allows the carrier plate 97 to be lifted out of the carrier frame 94, enabling removal and installation. The carrier plate 97 is constructed of a hard aluminum alloy, increasing its strength and reducing burn-through defects caused by short-duration laser beam exposure. Simultaneously, the laser generator 50's transmission power and focal position must be controlled. Proper laser power settings can minimize burn-through of the carrier plate 97, ensuring excellent cutting quality and eliminating melt marks.

[0062] See also Figure 8-12 A rubber outer ring 98 is embedded in the concave hole, and a nozzle inner ring 99 is embedded in the rubber outer ring 98. An air pressure sensor is installed inside the nozzle inner ring 99. The outer side of the nozzle inner ring 99 is threadedly connected to a locking nut 910. The nozzle inner ring 99 is detachably mounted on the support plate 97 through the locking nut 910. A three-way joint 911 is installed at the bottom of the nozzle inner ring 99. Two adjacent three-way joints 911 are connected by a hose 912. The hose 912 is connected to the air pipe 913, and the air pipe 913 is connected to the vacuum negative pressure pump. The vacuum negative pressure pump is installed inside the cabinet 10.

[0063] Specifically, the suction end of the vacuum negative pressure pump is interconnected with the air pipe 913, the hose 912, and the three-way connector 911, which then forms a negative pressure suction force inside the inner ring 99 of the suction nozzle. When the battery cell falls on the inner ring 99 of the suction nozzle, the battery cell will be negatively adsorbed. At the same time, there is an air pressure sensor inside the inner ring 99 of the suction nozzle, which can well detect the suction force on the battery cell, increase the connection strength of the battery cell, and prevent the position of the battery cell from shifting. At the same time, the position of the inner ring 99 of the suction nozzle must ensure that it is always staggered with the laser beam emitted by the laser generator to prevent the laser beam from burning the sensor in the inner ring 99 of the suction nozzle. It can also control the laser focus position of the laser generator 50 to always be on the battery cell.

[0064] See also Figure 13-14, mounting grooves 961 are provided on both sides of the U-shaped frame 96, and a groove plate 962 is fixedly installed at the opening of the mounting groove 961. A clamping head 963 is movably inserted on the inner groove plate 962, and a limiting ring 964 is fixedly installed on the side of the clamping head 963. A pushing spring 965 is fixedly installed on the side of the limiting ring 964. The limiting ring 964 and the pushing spring 965 are both located inside the mounting groove 961.

[0065] Specifically, when the support plate 97 is tilted and disassembled, its clamping head 963 is squeezed back into the interior of the installation groove 961 by the squeezing of the cross bar 95. When the clamping head 963 passes the position of the cross bar 95, its U-shaped frame 96 and the cross bar 95 are no longer locked with each other; on the contrary, when the support plate 97 is installed in the interior of the support frame 94, its U-shaped frame 96 just spans the cross bar 95, and its pushing spring 965 pushes the clamping head 963 out, and the clamping head 963 rests on the cross bar 95, thereby locking the two.

[0066] Based on the second embodiment, the third embodiment is formed: Figure 15-18 The reciprocating drive assembly 100 includes a number of brackets 101, which are fixedly installed on the top of the cabinet 10, and a connecting plate 102 is installed between the brackets 101. A guide rail 103 is fixedly installed on the inner bottom wall of the connecting plate 102, and a double-sided rack 104 is slidably installed inside the connecting plate 102. The bottom of the X-shaped frame 93 is fixedly installed on the top of the double-sided rack 104, and a slide groove 105 corresponding to the guide rail 103 is opened at the bottom of the double-sided rack 104. The double-sided rack 104 slides inside the connecting plate 102 through the guide rail 103 and the slide groove 105.

[0067] Specifically, when the double-sided rack 104 slides back and forth, the bottom plate 91 and the supporting frame 94 are moved back and forth through the X-shaped frame 93 .

[0068] See also Figure 15-18 , sector gears 106 are provided on both sides of the double-sided rack 104. When one of the sector gears 106 is engaged with one side of the double-sided rack 104, the other sector gear 106 does not contact one side of the double-sided rack 104. A shaft 107 is fixedly installed inside the sector gear 106, and a transmission gear 108 is fixedly installed on the upper end of the shaft 107. The lower end of the shaft 107 is fixed on the upper surface of the cabinet 10; a driving gear 109 is engaged between the two transmission gears 108, and the driving gear 109 is fixedly installed on the output end of the driving servo motor 111, and the driving servo motor 111 is installed on the upper surface of the cabinet 10.

[0069] Specifically, the driving servo motor 111 drives the driving gear 109 to rotate, and the driving gear 109 drives the transmission gears 108 on both sides to rotate, and the transmission gear 108 drives the sector gear 106 to rotate synchronously, and one of the sector gears 106 drives the double-sided rack 104 to slide forward. When the tail end of the sector gear 106 disengages from one side of the double-sided rack 104, the other sector gear 106 continues to engage with the other side of the double-sided rack 104, and then the double-sided rack 104 will slide back, so that the double-sided rack 104 will perform a reciprocating mode of forward-backward-forward, and then the tray assembly 90 will also perform a reciprocating mode. Compared with the traditional operation that requires the motor to reverse and return, the driving servo motor 111 in this application only needs to rotate continuously to move the tray assembly 90 forward and backward without any delay or jamming in between. This can also ensure that the tray assembly 90 moves forward at a uniform speed during the forward movement and quickly retreats during the backward movement. At the same time, it is linked with the jet assembly 60. When the tray assembly 90 moves forward, the jet assembly 60 sprays cold air. When the tray assembly 90 moves backward, the jet assembly 60 does not spray cold air, thereby saving the use of cold air.

[0070] When in use, a method for separating and sliding a battery cell comprises the following steps:

[0071] S1: According to the number and size of the cell cuts, the corresponding laser generators 50 are pre-activated. If the cell is cut into two parts, the middle group of laser generators 50 is activated; if the cell is cut into three parts, the two groups of laser generators 50 on both sides are activated; if the cell is cut into four parts, the three groups of laser generators 50 are activated; the spacing between the three groups of laser generators 50 can be adjusted using the transverse movement assembly 40 to meet the cell cutting requirements.

[0072] S2: The battery cell is transferred to the tray assembly 90 via the transfer roller 70. The vacuum negative pressure pump is operated, and the inner ring 99 of the suction nozzle forms a negative pressure suction force, which can absorb and lock the battery cell. The air pressure sensor in the inner ring 99 of the suction nozzle can constantly detect the negative pressure suction force of each inner ring 99 of the suction nozzle to prevent the battery cell from being broken due to excessive suction force, and the battery cell from being moved due to insufficient pressure.

[0073] S3: The double-sided rack 104 is driven to slide back and forth, driving the tray assembly 90 to slide back and forth. When the tray assembly 90 is driven to slide forward, the battery cells thereon are cut by the laser beam emitted by the laser generator 50;

[0074] S4: The front row of laser generators 50 pre-cuts a groove on the surface of the cell, and then the front air jet assembly 60 sprays cold air on the surface of the cell to cool it down. The rear row of laser generators 50 then cuts again on the groove, and the rear air jet assembly 60 sprays cold air on the surface of the cell again. The alternating hot and cold air allows the cell to automatically split along the cut groove.

[0075] S5: After the tray assembly 90 passes over the laser generator 50, the robotic arm 80 behind it takes away the cut battery cells and enters the next process.

[0076] To sum up, the battery cell segmentation slide device is inserted into the notched grooves at both ends of the support plate 97 through a tool, and the support plate 97 is tilted up. At the same time, the clamping head 963 is squeezed back into the installation groove 961 by force, and the clamping head 963 no longer interferes with the cross bar 95. The U-shaped frame 96 will also leave the cross bar 95, and then the entire support plate 97 is removed. By rotating the threaded sleeve on the top of the three-way joint 911, the three-way joint 911 can be disengaged from the inner ring 99 of the suction nozzle, and then the restriction on the inner ring 99 of the suction nozzle can be released by rotating the locking nut 910. Then the inner ring 99 of the suction nozzle can be removed from the rubber outer ring 98, thereby achieving the purpose of disassembling and repairing the damaged inner ring 99 of the suction nozzle.

[0077] The battery cell slicing slide device is configured with an air pressure sensor inside the inner ring 99 of the nozzle. Once the inner ring 99 of the nozzle forms a closed cavity with the battery cell, a negative pressure adsorption force is formed in the cavity. The air pressure sensor can detect the air pressure value in the cavity, and the air pressure value can be directly viewed through an external display screen, thereby detecting the adsorption force of the battery cell.

[0078] The battery cell slicing slide device, the battery cells enter the tray assembly 90 through the transfer roller 70, and there are multiple suction nozzle inner rings 99 on the surface of the tray assembly 90. The vacuum negative pressure pump inside the cabinet 10 is started, and the exhaust end of the vacuum negative pressure pump is interconnected with the hose 912, the air pipe 913 and the three-way joint 911. The exhaust end of the vacuum negative pressure pump exhausts air, and the suction nozzle inner ring 99 generates suction, which can negatively adsorb the battery cells falling on the top of the suction nozzle inner ring 99. There is an air pressure sensor in the suction nozzle inner ring 99. Once the battery cell is sucked, there is no gas flow in the cavity inside the suction nozzle inner ring 99. The air pressure sensor will detect the air pressure value in the cavity, thereby realizing negative pressure adsorption of the battery cell. Compared with the traditional suction cup, the negative pressure suction of the present application is adjustable, the adsorption area is large, and its adsorption force is also greater than the adsorption force of the suction cup, thereby ensuring that the battery cell is firmly adsorbed and the battery cell position will not be shifted due to vibration.
