Description

Technical Field

[0001] This utility model relates to the field of battery cell processing technology, and in particular to a battery cell leveling device and edge-wrapping system. Background Technology

[0002] During the processing of solar cells, the edges of the cells need to be edge-wrapped. Leveling the paper sheets is a crucial step in this process; only by accurately positioning the cells can the quality of the subsequent adhesive coating and edge wrapping be guaranteed. Existing edge-wrapping systems require high-precision camera vision alignment and software-based visual algorithm positioning to adjust the edge position. After photographing each cell, adjustments are needed in the X, Y, and R directions to ensure the edge-wrapping position of each cell is as consistent as possible before coating and wrapping. This results in high costs for the leveling device and increases the overall cost of the edge-wrapping system. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a battery cell leveling device and edge-wrapping system, which abandons the traditional visual inspection mechanism and uses a mechanical structure to achieve battery cell leveling, saving costs, facilitating edge wrapping, and improving edge-wrapping quality.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a battery cell leveling device for leveling polygonal battery cells, the leveling device comprising:

[0005] An edge-adjusting mechanism includes a lifting drive and a leveling roller. Multiple leveling rollers are spaced apart along a first direction of the horizontal plane. All leveling rollers are at the same height and move up and down synchronously under the drive of the lifting drive.

[0006] A pendulum mechanism is located above the edge adjustment mechanism. The pendulum mechanism includes a vertically arranged upright rod that can move up and down and is clamped by a clamping component to limit its height position. A rotary motor is fixed on the upright rod, and an adsorption platform for adsorbing the battery cell is fixed at the output end of the rotary motor.

[0007] During the upward movement of the leveling roller, the solar cell with the offset angle can be pushed to rotate until the bottom edge of the solar cell abuts against all the leveling rollers to make the bottom edge horizontal, and the upright can be pushed upward.

[0008] The beneficial effects of this utility model are as follows:

[0009] When the leveling roller moves upward by the set stroke, it pushes the angled solar cell to rotate until its bottom edge is against all the leveling rollers. At this point, the bottom edge of the solar cell is horizontal, and the solar cell is adjusted to the specified angle. The leveling roller also pushes the upright rod upward during its movement to ensure the solar cell is in place. After the leveling roller moves upward by the set stroke, the clamping assembly clamps and limits the height of the upright rod, and the rotation shaft of the rotary motor is locked, placing the adsorption table and the solar cell on it at the adjusted angle and height. This system utilizes a purely mechanical structure, with a vertically movable upright rod and a clamping mechanism that limits its position. Combined with a rotary motor that shuts off when power is off, it works in conjunction with the edge-adjusting mechanism to level the bottom edge of each solar cell that needs to be edge-wrapped.

[0010] Furthermore, the clamping assembly includes a fixed rod and a telescopic rod that can move up and down along the fixed rod. The telescopic rod is fixedly connected to the upright. The fixed rod is provided with a clamping part. The clamping part includes grippers located on both sides of the telescopic rod and capable of moving synchronously relative to each other or in opposite directions. When the grippers are close together, they can limit the height position of the telescopic rod.

[0011] Furthermore, each of the uprights is connected to at least two of the clamping assemblies, which are spaced apart along a first direction. By using multiple clamping assemblies to limit the height of the upright, the problem of the upright sliding down due to malfunction of a single clamping assembly can be avoided.

[0012] Furthermore, multiple suspension mechanisms are spaced apart along a second direction in the horizontal plane. Each suspension mechanism attracts a battery cell that is vertical and extends along the second direction. The battery cells attracted by multiple suspension mechanisms can be simultaneously leveled at the edge-adjusting mechanism. The fixing rods of all suspension mechanisms are fixed to a connecting plate. At this time, when the leveling roller rises and falls, the battery cells on multiple suspension mechanisms can be leveled simultaneously.

[0013] Furthermore, the rotary motor is de-energized when the leveling roller moves upward, and energized when the clamping assembly defines the height position of the upright to constrain the battery cell to a horizontal state at the bottom edge.

[0014] Furthermore, the leveling roller is a polyurethane roller.

[0015] This utility model also discloses an edge-wrapping system, including a feeding mechanism, the aforementioned edge-adjusting mechanism, edge-wrapping mechanism, curing mechanism, and unloading mechanism arranged sequentially along a second direction in a horizontal plane. The edge-wrapping system also includes a transverse swing device, the output end of which is provided with multiple aforementioned suspension mechanisms. The transverse swing device can drive all the suspension mechanisms to move sequentially to the feeding mechanism, the edge-adjusting mechanism, the edge-wrapping mechanism, the curing mechanism, and the unloading mechanism.

[0016] Furthermore, the edge-wrapping mechanism includes a liftable coating platform. The coating platform includes a coating surface that abuts against the bottom edge of the battery cell. A scraper for applying edge-wrapping adhesive to the coating surface is slidably connected to the coating platform. The edge-wrapping mechanism employs transfer printing technology, which solves the problem of adhesive uniformity and allows for edge-wrapping processes with relatively thin thicknesses.

[0017] Furthermore, both the feeding mechanism and the unloading mechanism include a conveyor line and a buffer rack. The buffer rack includes a plurality of placement positions distributed vertically for placing one of the battery cells. The buffer rack can move up and down to align the placement positions with the conveyor line in sequence.

[0018] Furthermore, the lateral swing device includes a linear module and a rotating mechanism connected to the linear module. The linear module is used to drive the rotating mechanism to move along a first direction. The suspension mechanism is connected to the rotating mechanism through a connecting plate. The rotating mechanism can drive all the suspension mechanisms to rotate. Attached Figure Description

[0035] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0036] In the figures below, the first direction is the X direction, the second direction is the Y direction, the first direction and the second direction are perpendicular in the horizontal plane, and the vertical direction is the Z direction.

[0037] This utility model discloses a leveling device for a battery cell 8, used for leveling a polygonal battery cell 8 to ensure that the bottom edge of the battery cell 8 is horizontal, facilitating subsequent edge wrapping. For example, the battery cell 8 is square.

[0038] See appendix Figure 1 As shown, the leveling device includes an edge adjustment mechanism 1 and a suspension mechanism 2 located above the edge adjustment mechanism 1. The suspension mechanism 2 is used to adsorb the battery cell 8 and cooperates with the edge adjustment mechanism 1 to achieve the leveling of the battery cell 8.

[0039] See appendix Figure 1 and attached Figure 2 As shown, the edge adjustment mechanism 1 includes a lifting drive 11 and leveling rollers 12. Multiple leveling rollers 12 are spaced apart along a first direction on the horizontal plane. All leveling rollers 12 are at the same height and move synchronously under the drive of the lifting drive 11. Multiple leveling rollers 12 can contact multiple points on the bottom edge of the battery cell 8 to adjust the angle of the battery cell 8. The suspension mechanism 2 includes a vertically arranged upright 21. The upright 21 can move up and down and is clamped by a clamping assembly 22 to limit its height position. A rotary motor 23 is fixed on the upright 21, and an adsorption platform 24 for adsorbing the battery cell 8 is fixed to the output end of the rotary motor 23.

[0040] During the upward movement of the leveling roller 12, it can push the angled battery cell 8 to rotate until the bottom edge of the battery cell 8 is in contact with all the leveling rollers 12. At this time, the bottom edge of the battery cell 8 is horizontal, and the battery cell 8 is adjusted to the specified angle. During the movement, the leveling roller 12 can also push the upright rod 21 upward to ensure that the battery cell 8 has been adjusted into place. After the leveling roller 12 has moved upward, the clamping assembly 22 clamps the limiting upright rod 21, limiting the limiting rod to the height position at this time, and the rotation shaft of the rotary motor 23 is locked, limiting the adsorption table 24 and the battery cell 8 on it to the set angle and height.

[0041] The leveling device in this embodiment abandons traditional visual inspection and instead utilizes a purely mechanical structure. It employs a vertically movable pole 21 and a clamping assembly 22 that limits its position, along with a rotary motor 23 that shuts off when power is off. This, in conjunction with the edge-adjusting mechanism 1, completes the leveling of the bottom edge of each battery cell 8 that currently requires edge wrapping. By avoiding the use of conventional camera-based visual positioning and correction, costs are saved, while still meeting subsequent adhesive application requirements.

[0042] The rotary motor 23 is de-energized when the leveling roller 12 moves upward. At this time, the motor shaft of the rotary motor 23 can rotate under the action of external force, thereby adjusting the angle of the battery cell 8. When the clamping assembly 22 limits the height position of the upright 21, the angle of the battery cell 8 has been adjusted to the correct position. Therefore, the rotary motor 23 is energized to limit the battery cell 8 to a horizontal position at the bottom edge.

[0043] See appendix Figure 4 As shown, the clamping assembly 22 includes a fixed rod 221 and a telescopic rod 222 that can move up and down along the fixed rod 221. The telescopic rod 222 is fixedly connected to the upright rod 21. A clamping part 223 is provided on the fixed rod 221. The clamping part 223 includes grippers located on both sides of the telescopic rod 222 and capable of moving synchronously relative to or away from each other. When the grippers are close together, they can limit the height position of the telescopic rod 222. A clamping cylinder is fixed on the fixed rod 221 for driving the grippers to move.

[0044] The telescopic rod 222 moves upward under the push of the leveling roller 12. When the leveling roller 12 moves upward, the grippers are in a distanced state, and the position of the telescopic rod 222 is not restricted, so that the telescopic rod 222 can move upward. However, initially, the grippers can also hold the telescopic rod 222 to ensure that the telescopic rod 222 will not move, but at this time the height of the telescopic rod 222 is lower than the height of the leveled telescopic rod 222. A limit block can also be set in the fixed rod 221 to limit the downward movement of the telescopic rod 222 and prevent the telescopic rod 222 from sliding out of the fixed rod 221 under the action of gravity.

[0045] The travel setting of the leveling roller 12 is manually set. It needs to ensure that while adjusting the angle of the solar cell 8, it can also push the telescopic rod 222 upward to meet the leveling requirements of the solar cell 8. Generally speaking, the offset angle of the solar cell 8 will not be too large.

[0046] For example, see Appendix Figure 2 As shown in (a), the battery cell 8 is tilted at an angle of (+θ). When the lower leveling roller 12 moves upward under the drive of the lifting drive component 11, the rotary motor 23 is switched off via a signal synchronization control. At this time, the lower leveling roller 12 slowly rises until it begins to contact the side of the tilted bottom edge of the battery cell 8. Then, the motor shaft of the rotary motor 23 slowly rotates to straighten the angle of the battery cell 8, and finally, the other side of the tilted bottom edge of the battery cell 8 also contacts the leveling roller. At this time, the side of the battery cell 8 that needs to be edged is completely flat with the lower edge-adjusting adhesive, and the battery cell 8 has been leveled. After the lower leveling roller 12 continues to slowly rise and move a set stroke Z, the upright rod 21 and the telescopic rod 222 also retract by a stroke Z. Finally, the clamping blocks on both sides of the telescopic rod 222 are driven by the clamping cylinder to move closer to each other to clamp the telescopic rod 222 and prevent it from changing. See Appendix for details. Figure 2 As shown in (b), the battery cell 8 is in a leveling state.

[0047] For example, see Appendix Figure 3 As shown in (a), the battery cell 8 has a negative tilt angle (-θ) and a downward offset H. When the lower leveling roller 12 moves upward under the drive of the lifting drive component 11, the rotary motor 23 is switched off by the signal synchronous control. At this time, the lower leveling roller 12 slowly rises until it begins to contact the side of the tilted bottom edge of the battery cell 8. Then, the motor shaft of the rotary motor 23 slowly rotates to straighten the angle of the battery cell 8, and finally the other side of the tilted bottom edge of the battery cell 8 also contacts the leveling roller. At this time, the side of the battery cell 8 that needs to be edged is completely flat with the lower edge-adjusting adhesive, and the battery cell 8 has been leveled. After the lower leveling roller 12 continues to slowly rise and move a set stroke Z, the upright 21 and the telescopic rod 222 retract by a stroke Z+H. Finally, the clamping blocks on both sides of the telescopic rod 222 are driven by the clamping cylinder to move closer to each other to clamp the telescopic rod 222 and prevent it from changing. See Appendix for details. Figure 3 As shown in (b), the battery cell 8 is in a leveling state.

[0048] In one embodiment, each upright 21 is connected to at least two clamping assemblies 22, which are spaced apart along a first direction. By using multiple clamping assemblies 22 to limit the height of the upright 21, the problem of the upright 21 sliding down due to an abnormality in a single clamping assembly 22 can be avoided.

[0049] In one embodiment, to simultaneously level multiple battery cells 8, multiple suspension mechanisms 2 are spaced apart along a second direction in the horizontal plane. Each suspension mechanism 2 holds a battery cell 8 in a vertical position and extends along the second direction. The battery cells 8 held by multiple suspension mechanisms 2 can be simultaneously leveled at the edge-adjusting mechanism 1. The fixing rods 221 of all suspension mechanisms 2 are fixed to a connecting plate 73. At this time, when the leveling roller 12 rises and falls, it can simultaneously level the battery cells 8 on multiple suspension mechanisms 2.

[0050] In one embodiment, the leveling roller 12 is a polyurethane roller.

[0051] In one embodiment, an edge-wrapping system is also disclosed for wrapping the edge of the battery cell 8.

[0052] See appendix Figure 5 and attached Figure 6 As shown, the edge-binding system includes a feeding mechanism 3, the edge-adjusting mechanism 1, the edge-binding mechanism 4, the curing mechanism 5, and the unloading mechanism 6 arranged sequentially along the second direction in the horizontal plane. The edge-binding system also includes a transverse swing device 7. The output end of the transverse swing device 7 is provided with multiple suspension mechanisms 2. The transverse swing device 7 can drive all the suspension mechanisms 2 to move sequentially to the feeding mechanism 3, the edge-adjusting mechanism 1, the edge-binding mechanism 4, the curing mechanism 5, and the unloading mechanism 6.

[0053] The battery cells 8 are fed at the feeding mechanism 3, and each battery cell 8 is held in place by multiple suspension mechanisms 2. They are then moved to the edge-wrapping mechanism 4 by a lateral swing device 7. The edge-wrapping mechanism 4 and the suspension mechanisms 2 work together to level the battery cells 8, ensuring that the bottom edges of all battery cells 8 are at the same height and horizontal. Next, the lateral swing device 7 moves the suspension structure above the edge-wrapping mechanism 4 to apply adhesive to the bottom edges of all battery cells 8. Then, the lateral swing device 7 moves the suspension structure above the curing mechanism 5 to perform UV curing on the wrapped bottom edges. The lateral swing device 7 then moves the suspension structure above the edge-wrapping mechanism 4 again, and the rotary motor 23 rotates 90 degrees, allowing the other side of the battery cell 8 to be used as the bottom edge for adhesive application. This process is repeated until all edges of the battery cells 8 have been coated and cured. Finally, all battery cells 8 are unloaded at the unloading mechanism 6.

[0054] Both the loading mechanism 3 and the unloading mechanism 6 include a conveyor line 31 and a buffer rack 32. The buffer rack 32 includes multiple placement positions for placing one solar cell 8, distributed vertically. The buffer rack 32 can move up and down to align the placement positions with the conveyor line 31 in sequence. Each placement position corresponds to a cantilever mechanism, allowing multiple cantilever mechanisms to load and unload multiple solar cells 8.

[0055] For the feeding mechanism 3, the buffer rack 32 is initially at its lowest point, with the uppermost placement position aligned with the conveyor line 31. When the battery cell 8 moves to the end of the conveyor line 31, it is already inserted into the uppermost placement position. The buffer rack 32 moves upward to lift the battery cell 8, separating it from the conveyor line 31, until the second layer placement position in the buffer rack 32 aligns with the conveyor line 31. When the battery cell 8 on the conveyor line 31 enters the second layer placement position, the buffer rack 32 moves up another layer, and so on, until each layer in the buffer rack 32 has placed the battery cell 8, waiting for the cantilever mechanism to grab it. The unloading mechanism 6 operates in the opposite manner to the feeding mechanism 3. The buffer rack 32 of the unloading mechanism 6 is filled with battery cells 8 and descends layer by layer from the highest position, placing the battery cells 8 from the placement positions onto the conveyor line 31 in sequence.

[0056] The lateral swing device 7 includes a linear module and a rotating mechanism 72 connected to the linear module 71. The linear module drives the rotating mechanism 72 to move along a first direction. The suspension mechanism 2 is connected to the rotating mechanism 72 via a connecting plate 73. The rotating mechanism 72 can drive all suspension mechanisms 2 to rotate. The rotating mechanism 72 can be a motor, driving the suspension mechanism 2 to rotate 90°. Therefore, the battery cells 8 are in a horizontal state at the feeding mechanism 3 and the unloading mechanism 6, but in a vertical state at the edge adjusting mechanism 1, the edge wrapping mechanism 4, and the curing mechanism 5. Therefore, the rotating mechanism 72 drives all suspension mechanisms 2 to rotate synchronously.

[0057] See appendix Figure 7 As shown, the edge-binding mechanism 4 is located below the suspension mechanism 2. The edge-binding mechanism 4 includes a lifting and lowering adhesive-coating platform 41. The adhesive-coating platform 41 includes an adhesive-coating surface that can abut against the bottom edge of the battery cell 8. A scraper 42 for applying edge-binding adhesive to the adhesive-coating surface is slidably connected to the adhesive-coating platform 41.

[0058] First, a row of edge-sealing adhesive is evenly applied to the coating platform 41. Then, the automatic adhesive scraper control mechanism controls the scraper rod 42 to move uniformly from one end of the coating platform 41 to the other end at a certain interval and speed, thus completing the uniform application of the edge-sealing adhesive. At this time, a layer of edge-sealing adhesive should be evenly applied to the coating platform 41 (the coating thickness is closely related to the ink characteristics, viscosity, the required edge-sealing thickness, and the gap and speed of the wire rods, etc.). After the pendulum mechanism 2 moves horizontally to directly above the coating platform 41, the coating platform 41 rises to the edge-sealing height, contacts the bottom edge of the battery cell 8 that needs to be edge-sealed, and then quickly descends, thus completing the edge-sealing action.

[0059] The edge-binding mechanism 4 also includes a second lifting drive 43 for driving the rubber-coating platform 41 to lift.

[0060] In existing technologies, the industrial-scale edge-wrapping method for battery cells 8 is generally roller coating or immersion coating. This method results in edge-wrapping lines and morphology that are affected by various factors, leading to unstable edge-wrapping quality. In this embodiment, the edge-wrapping mechanism 4 employs transfer printing technology, which solves the problem of adhesive uniformity and enables thinner edge-wrapping processes. The selection of the adhesive scraper 42 generally follows standardized specifications, allowing for the selection of a suitable scraper model based on the desired edge-wrapping thickness.

[0061] The curing mechanism 5 includes a curing table with multiple UV lamps. When the suspension mechanism 2 moves horizontally to directly above the curing table, the UV lamps are lit to complete the curing of the edge-sealing adhesive.

[0062] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
