Description

Technical Field

[0001] This utility model relates to the field of battery technology, specifically to a current collector welding device and an integrated equipment for welding and coating battery cells. Background Technology

[0002] In the production process of lithium batteries, it is necessary to weld the current collectors and wrap the circumference of the battery electrodes. The former is to connect the electrodes of the entire cell to form a whole, while the latter is to ensure the insulation of the electrodes inside the battery and prevent them from contacting the steel shell. Both of these processes are indispensable parts of lithium battery production.

[0003] Both ends of the battery cell require the welding of current collectors. Currently, the current collectors are welded to one end of the battery cell, and then the battery cell is manually rotated before the current collectors are welded to the other end of the battery cell. This process is cumbersome, time-consuming, labor-intensive, and results in low production efficiency. Utility Model Content

[0043] Please see Figure 1 This utility model provides a collector welding device in one embodiment, comprising: a first cell flipping welding mechanism 10, a cell rotating mechanism 20, a second cell flipping welding mechanism 30, and a cell conveying mechanism 50;

[0044] The first cell flipping and welding mechanism 10, the cell rotating mechanism 20, and the second cell flipping and welding mechanism 30 are arranged sequentially along the conveying direction of the cell conveying mechanism 50.

[0045] The first cell flipping and welding mechanism 10 and the second cell flipping and welding mechanism 30 are respectively used to weld the processing current collector to the two end electrodes of the processing cell 60.

[0046] The cell rotation mechanism 20 includes a plurality of cell grippers 21, a lifting drive assembly 22 and a rotation drive assembly 23. The cell grippers 21 are arranged above the cell conveying mechanism 50. The lifting drive assembly 22 is driven to the cell grippers 21 and is used to drive the cell grippers 21 to lift. The rotation drive assembly 23 is driven to the cell grippers 21 and is used to drive the cell grippers 21 to rotate.

[0047] The cell conveying mechanism 50 is used to convey the processed cell 60.

[0048] The working principle of the manifold welding device according to one embodiment of the present invention is explained below:

[0049] In this embodiment, the first cell flipping welding mechanism 10 performs current collector welding on the positive electrode of the cell, and the second cell flipping welding mechanism 30 performs current collector welding on the negative electrode of the cell. The subcontracted battery cell 60 is placed horizontally on the battery cell conveying mechanism 50. After the battery cell conveying mechanism 50 conveys the subcontracted battery cell 60 to the first battery cell flipping and welding mechanism 10, the first battery cell flipping and welding mechanism 10 performs current collector welding on the positive electrode of the subcontracted battery cell 60 on the battery cell conveying mechanism. Then the subcontracted battery cell 60 is conveyed to the battery cell rotating mechanism 20. The lifting drive component 22 of the battery cell rotating mechanism 20 drives the battery cell gripper 21 to descend and grab the subcontracted battery cell 60. Then the lifting drive component 22 drives the battery cell gripper 21 to rise. Then the rotation drive component 23 drives the battery cell gripper 21 to rotate 180°, so that the angle of the battery cell is reversed. Then the subcontracted battery cell 60 moves to the second battery cell flipping and welding mechanism 30. The second battery cell flipping and welding mechanism 30 performs current collector welding on the negative electrode of the subcontracted battery cell 60 on the battery cell conveying mechanism, thereby realizing the current collector welding of the positive and negative electrodes of the battery cell.

[0050] Please see Figure 2 and Figure 3The specific structure of the rotary drive assembly 23 can be designed according to actual needs. For example, in some optional embodiments, the rotary drive assembly 23 includes a fixed base 231, a rotating base 232, a transmission gear 233, a transmission rack 234, and a rack translation drive module 235. The transmission gear 233 is rotatably mounted on the fixed base 231, and the rotating base is connected to the transmission gear 233. The transmission rack 234 is movably mounted on the fixed base 231 and meshes with the transmission gear 233. The rack translation drive module 235 is drivenly connected to the transmission rack 234. When the transmission rack 234 moves under the drive of the rack translation drive module 235, the transmission rack 234 can drive the transmission gear 233 to rotate. When the transmission gear 233 rotates, it can drive the rotating base to rotate.

[0051] The specific structure of the rack translation drive module 235 can be designed according to actual needs. For example, the rack translation drive module 235 can use electric cylinders, pneumatic cylinders, hydraulic cylinders, etc.

[0052] The specific structure of the lifting drive assembly 22 can be designed according to actual needs. For example, the lifting drive assembly 22 can be a lead screw drive assembly, a rotary motor translation drive assembly, a belt translation drive assembly, a cylinder translation drive assembly, or a linear motor translation drive assembly.

[0053] The specific structure of the battery cell gripper 21 can be designed according to actual needs. For example, the battery cell gripper 21 can adopt a finger cylinder or other suitable structure.

[0054] The connection method between the lifting drive assembly 22, the rotation drive assembly 23, and the cell clamp 21 can be designed according to actual needs. For example, in this embodiment, the lifting drive assembly 22 is driven to connect with the fixed base 231, and the cell clamp 21 is set on the rotating base. The lifting drive assembly 22 drives the fixed base 231 to rise and fall, thereby realizing the lifting and falling of the rotation drive assembly 23, and then driving the cell clamp 21 to rise and fall. Alternatively, in other embodiments, the lifting drive assembly 22 is set on the rotating base and driven to connect with the cell clamp 21. The rotating base drives the lifting drive assembly 22 and the cell clamp 21 to rotate together, while the lifting drive assembly 22 directly drives the cell clamp 21 to rise and fall.

[0055] In some optional embodiments, the cell rotation mechanism 20 includes a plurality of cell grippers 21 arranged sequentially along the conveying direction of the cell conveying mechanism 50. The plurality of cell grippers 21 can simultaneously grip a plurality of processed cells 60, thereby enabling the cell rotation mechanism 20 to move and adjust the angle of the plurality of cell grippers 21 at one time.

[0056] Please see Figure 4In some optional embodiments, the collector welding device further includes a cell centering mechanism 40. The cell centering mechanism 40, the first cell flipping welding mechanism 10, the cell rotating mechanism 20, and the second cell flipping welding mechanism 30 are arranged sequentially along the conveying direction of the cell conveying mechanism 50. The cell centering mechanism 40 includes two centering clamps 41 and a clamping plate driving assembly 42. The two centering clamps 41 are respectively disposed on both sides of the cell conveying mechanism 50. The clamping plate driving assembly 42 is drivenly connected to the two centering clamps 41. The two centering clamps 41 move closer to each other and further away from each other under the drive of the clamping plate driving assembly 42. The two centering clamps 41 move closer to each other under the drive of the clamping plate driving assembly 42, so that the two centering clamps 41 can clamp the processing cell 60 located on the cell conveying mechanism 50, so that the processing cell 60 is clamped and positioned, thereby determining the position of the processing cell 60 relative to the cell conveying mechanism 50. Then the two centering clamps 41 move away from each other, thereby releasing the processing cell 60.

[0057] The specific structure of the clamping plate drive assembly 42 can be designed according to actual needs. For example, the clamping plate drive assembly 42 includes two drive assemblies, which are connected to the centering clamping plate 41. The two drive assemblies can be a lead screw drive assembly, a rotary motor translation drive assembly, a belt translation drive assembly, a cylinder translation drive assembly, or a linear motor translation drive assembly, and are not limited to this example.

[0058] Please see Figures 5 to 7 In some optional embodiments, the first cell flipping welding mechanism 10 and the second cell flipping welding mechanism 30 both include a cell lifting assembly 110, a cell lifting assembly 120, a current collector positioning seat 130, a flipping clamping assembly 140 and a welding assembly 150.

[0059] The cell lifting assembly 110 is used to drive the processing cell 60 located on the cell conveying mechanism 50 to rise and fall;

[0060] The cell lifting assembly 120 is arranged on one side of the cell lifting assembly 110;

[0061] The current collector positioning seat 130 is positioned above the cell lifting assembly 120;

[0062] The flipping clamping assembly 140 includes a flipping drive module 141 and a plurality of battery cell clamping modules 142 arranged sequentially along the conveying direction of the battery cell conveying mechanism 50. The flipping drive module 141 is driven to the battery cell clamping modules 142. Under the drive of the flipping drive module 141, the battery cell clamping modules 142 rotate downward to a first position located at the top of the battery cell lifting assembly 110 and rotate upward to a second position located between the battery cell lifting assembly 120 and the current collector positioning seat 130.

[0063] The welding assembly 150 is positioned above the manifold positioning seat 130.

[0064] The working principle of the first cell flipping and welding mechanism 10 and the second cell flipping and welding mechanism 30 is the same. The working principle of the first cell flipping and welding mechanism 10 is explained below:

[0065] When the cell clamping module 142 is in the first position, the cell lifting assembly 110 can lift the processing cell 60 on the cell conveying mechanism 50 from the cell conveying mechanism 50, so that the processing cell 60 is located at the cell clamping module 142. Then, the cell clamping module 142 clamps the processing cell 60. The flipping drive module 141 drives the cell clamping module 142 to rotate upward to the second position. Then, the cell lifting assembly 120 pushes the processing cell 60 on the cell clamping module 142 upward, so that the processing cell 60... The top electrode moves toward the processing current collector on the current collector positioning seat 130. Then the welding assembly 150 welds the processing current collector onto the electrode of the processing cell 60. Next, the cell lifting assembly 120 descends, and the flipping drive module 141 drives the cell clamping module 142 to rotate back to the first position. Then, the cell clamping module 142 releases the processing cell 60, so that the processing cell 60 is placed on the cell lifting assembly 110. Then, the cell lifting assembly 110 descends to place the processing cell 60 back onto the cell conveying mechanism 50.

[0066] Since the battery cells 60 being processed can be taken away from the battery cell conveying mechanism 50 for processing and then put back onto the battery cell conveying mechanism 50, the degree of automation can be effectively improved. This facilitates integration with other processing structures to form an integrated device, increases the integration of the equipment, and helps improve production efficiency.

[0067] The specific structure of the flip drive module 141 can be designed according to actual needs. For example, the flip drive module 141 can adopt a flip drive motor.

[0068] Please see Figure 8In some optional embodiments, the cell lifting assembly 110 includes a first support base 111, a second support base 112 and a lifting drive module 113. A conveying clearance space 114 for the cell conveying mechanism 50 is formed between the first support base 111 and the second support base 112. The lifting drive module 113 is drivenly connected to the first support base 111 and the second support base 112. The cell conveying mechanism 50 passes through the conveying clearance space 114. The first support base 111 and the second support base 112 are distributed on both sides of the cell conveying mechanism 50. The processing cell 60 extends from both sides of the cell conveying mechanism 50. Therefore, when the first support base 111 and the second support base 112 rise under the drive of the lifting drive module 113, the first support base 111 and the second support base 112 can support the parts of the processing cell 60 that extend from both sides of the cell conveying mechanism 50, thereby lifting the processing cell 60. After the first support base 111 and the second support base 112 descend, the processing cell 60 can be placed on the cell conveying mechanism 50.

[0069] The specific structure of the lifting drive module 113 can be designed according to actual needs. For example, the lifting drive module 113 can be an electric cylinder, a pneumatic cylinder, a hydraulic cylinder, etc., and is not limited to this example.

[0070] In some alternative embodiments, the first support 111 and the second support 112 are connected by a connecting beam 115, and the lifting drive module 113 is arranged on one side of the conveying clearance space 114 and is drivenly connected to the first support 111. The connecting beam 115 can connect the first support 111 and the second support 112 together, and the lifting drive module 113 only needs to drive the first support 111 to rise and fall, which can simultaneously drive the first support 111 and the second support 112 to rise and fall together.

[0071] In some optional embodiments, the first support 111 and the second support 112 are provided with a plurality of limiting grooves 1111. The positions of the limiting grooves 1111 of the first support 111 and the limiting grooves 1111 of the second support 112 correspond one to one. The battery cell conveying mechanism 50 has a plurality of processed battery cells 60. Each processed battery cell 60 can simultaneously extend into the corresponding limiting grooves 1111 of the first support 111 and the limiting grooves 1111 of the second support 112. The limiting grooves 1111 can prevent the processed battery cells 60 from shaking relative to the first support 111 and the second support 112.

[0072] In some optional embodiments, the cell lifting assembly 120 includes a plurality of lifting rods 121 and a lifting drive module 122. The lifting rods 121 are arranged on the collector plate positioning seat 130. The lifting drive module 122 is drivenly connected to the plurality of lifting rods 121. When the cell clamping module 142 is in the second position, the lifting rods 121 are correspondingly located below the cell clamping module 142 and abut against the bottom of the processed cell 60. When the lifting rods 121 rise, they can push the processed cell 60 to rise. When the lifting rods 121 fall, the processed cell 60 falls accordingly. It should be noted that when the lifting rods 121 fall, the cell clamping module 142 can slightly loosen the processed cell 60, so that the processed cell 60 can fall by gravity.

[0073] The specific structure of the lifting drive module 122 can be designed according to actual needs. For example, the lifting drive module 113 can use electric cylinders, pneumatic cylinders, hydraulic cylinders, etc., without being limited to this example.

[0074] The specific structure of the cell clamping module 142 can be designed according to actual needs. For example, the cell clamping module 142 can use a finger cylinder. In this embodiment, the cell clamping module 142 includes a clamping drive module 1421 and two clamping plates 1422. The two clamping plates 1422 clamp and cooperate under the drive of the clamping drive module 1421, and the two clamping plates 1422 cooperate to clamp the processed cell 60. When the cell clamping module 142 is in the second position, the lifting rods 121 of the cell lifting assembly 120 push the processed cell 60 upward one by one, thereby driving the processed cell 60 to rise relative to the two clamping plates 1422. After the current collector is welded, the lifting rods 121 descend, and the processed cell 60 descends under the action of gravity. The clamping plates 1422 can slightly loosen the processed cell 60, so that the processed cell 60 can descend. In addition, in this embodiment, after the first support base 111 and the second support base 112 lift the sub-processed battery cell 60, the clamping plate 1422 can extend between the first support base 111 and the second support base 112 to clamp the sub-processed battery cell 60.

[0075] The specific structure of the clamping drive module 1421 can be designed according to actual needs. For example, the lifting drive module 113 can be an electric cylinder, a pneumatic cylinder, a hydraulic cylinder, etc., and is not limited to this example.

[0076] The specific structure of the welding assembly 150 can be designed according to actual needs. For example, in some optional embodiments, the welding assembly 150 includes a two-axis translation drive module 151 and a laser module 152. The laser module 152 is arranged on the top of the collector plate positioning seat 130. The two-axis translation drive module 151 is drivenly connected to the laser module 152. The laser module 152 can move and be raised / lowered along the conveying direction of the cell conveying mechanism 50 under the drive of the two-axis translation drive module 151. The two-axis translation drive module 151 may include a first electric cylinder and a second electric cylinder. The first electric cylinder drives the second electric cylinder to rise / lower, and the second electric cylinder drives the laser module 152 to move along the conveying direction of the cell conveying mechanism 50. Of course, the structure of the two-axis translation drive module 151 is not limited to this, and those skilled in the art can also choose other suitable structures based on the teachings of this utility model.

[0077] Please see Figure 9 and Figure 10 In some optional embodiments, the top of the current collector positioning seat 130 is provided with a plurality of positioning slots 131 arranged sequentially along the conveying direction of the cell conveying mechanism 50. The positioning slots 131 are used to position and cooperate with the processing current collector. When the cell clamping module 142 is in the second position, the cell clamping module 142 is located below the positioning slots 131. After the lifting rod 121 lifts the processing cell 60, the processing cell 60 moves to the positioning slot 131. The top electrode of the processing cell 60 extends into the positioning slot 131, so that the processing current collector contacts the processing cell 60, and then the welding operation can be performed.

[0078] The first cell flipping welding mechanism 10 is used to weld the current collector of the positive electrode of the cell. Since the current collector of the positive electrode has a tab, in order to improve the positioning stability, in some optional embodiments, a tab positioning groove 132 is formed on one side of the positioning through groove 131 of the first cell flipping welding mechanism 10. The tab positioning groove 132 is used to position the tab of the current collector, so that the position of the current collector is stably positioned. Moreover, after welding, the position of the tab of the current collector relative to the current collector is the same for each current collector 60, which facilitates the processing of the tab in subsequent processes.

[0079] The aforementioned manifold welding device can be applied to a battery cell welding and coating integrated equipment, which includes: the aforementioned manifold welding device.

[0080] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
