Description

Technical Field

[0001] This utility model relates to the technical field, specifically to an integrated equipment for welding and coating battery cells. Background Technology

[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloys as the positive / negative electrode materials and a non-aqueous electrolyte solution. Due to the highly reactive chemical properties of lithium metal, its processing, storage, and use require very strict environmental control. With the development of science and technology, lithium-ion batteries have become the mainstream technology.

[0003] 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.

[0004] Since both the positive and negative terminals of the battery require welding current collectors, currently, a separate welding assembly is used for welding. Then, the battery orientation is manually or mechanically adjusted before welding. After welding, the battery is transferred to the tab bending mechanism for tab bending. Tab bending prevents the tabs from interfering with tape wrapping. Finally, after the tab bending is completed, the battery cell is wrapped. Because transferring the battery cells between different mechanisms requires placing multiple cells into and removing the turnover box, continuous production cannot be achieved.

[0044] Please see Figure 1 and Figure 2This utility model provides an integrated battery cell welding and coating equipment, comprising: a collector plate welding device 10, two collector plate feeding mechanisms 20, a battery cell tab bending mechanism 30, a battery cell coating mechanism 40, and a battery cell conveying mechanism 50.

[0045] The collector plate welding device 10, the cell tab bending mechanism 30 and the cell coating mechanism 40 are arranged sequentially along the conveying direction of the cell conveying mechanism 50. Two collector plate feeding mechanisms 20 are arranged on one side of the collector plate welding device 10. The cell conveying mechanism 50 is used to convey the processed cell 60.

[0046] The collector welding device 10 includes a first cell flipping welding mechanism 110, a cell rotating mechanism 120, and a second cell flipping welding mechanism 130;

[0047] The first cell flipping and welding mechanism 110, the cell rotating mechanism 120, and the second cell flipping and welding mechanism 130 are arranged sequentially along the conveying direction of the cell conveying mechanism 50.

[0048] The first cell flipping and welding mechanism 110 and the second cell flipping and welding mechanism 130 are respectively used to weld the processing current collector to the two end electrodes of the processing cell 60.

[0049] The cell rotation mechanism 120 includes a plurality of cell grippers 121, a lifting drive assembly 122 and a rotation drive assembly 123. The cell grippers 121 are arranged above the cell conveying mechanism 50. The lifting drive assembly 122 is driven to the cell grippers 121 and is used to drive the cell grippers 121 to lift. The rotation drive assembly 123 is driven to the cell grippers 121 and is used to drive the cell grippers 121 to rotate.

[0050] Two collector plate feeding mechanisms 20 are respectively arranged on one side of the first cell flipping and welding mechanism 110 and the second cell flipping and welding mechanism 130.

[0051] The specific structure of the battery cell conveying mechanism 50 can be designed according to actual needs. For example, the battery cell conveying mechanism 50 can adopt a mesh belt conveying mechanism, a roller conveying mechanism, a chain plate conveying mechanism, or a belt conveying mechanism. The battery cell conveying mechanism 50 is provided with multiple conveying seats arranged sequentially along the conveying direction of the battery cell conveying mechanism 50, and the battery cells 60 to be processed are placed on the conveying seats.

[0052] The working principle of the integrated battery cell welding and coating equipment according to one embodiment of this utility model is explained below:

[0053] In this embodiment, the first cell flipping welding mechanism 110 performs current collector welding on the positive electrode of the cell, and the second cell flipping welding mechanism 130 performs current collector welding on the negative electrode of the cell.

[0054] 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 110, the first battery cell flipping and welding mechanism 110 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 120. The lifting drive component 122 of the battery cell rotating mechanism 120 drives the battery cell gripper 121 to descend and grab the subcontracted battery cell 60. Then the lifting drive component 122 drives the battery cell gripper 121 to rise. Then the rotation drive component 123 drives the battery cell gripper 121 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 130. The second battery cell flipping and welding mechanism 130 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.

[0055] Next, the battery cell is transported to the tab bending mechanism for tab bending, and then the battery cell is transported to the battery cell coating mechanism 40 for coating. The battery cell can continuously complete the current collector welding, tab bending and coating processes, which effectively speeds up production efficiency.

[0056] Please see Figure 3 and Figure 4 The specific structure of the rotary drive assembly 123 can be designed according to actual needs. For example, in some optional embodiments, the rotary drive assembly 123 includes a fixed base 1231, a rotating base 1232, a transmission gear 1233, a transmission rack 1234, and a rack translation drive module 1235. The transmission gear 1233 is rotatably mounted on the fixed base 1231, and the rotating base is connected to the transmission gear 1233. The transmission rack 1234 is movably mounted on the fixed base 1231 and meshes with the transmission gear 1233. The rack translation drive module 1235 is drivenly connected to the transmission rack 1234. When the transmission rack 1234 moves under the drive of the rack translation drive module 1235, the transmission rack 1234 can drive the transmission gear 1233 to rotate. When the transmission gear 1233 rotates, it can drive the rotating base to rotate.

[0057] The specific structure of the rack translation drive module 1235 can be designed according to actual needs. For example, the rack translation drive module 1235 can use electric cylinders, pneumatic cylinders, hydraulic cylinders, etc.

[0058] The specific structure of the lifting drive assembly 122 can be designed according to actual needs. For example, the lifting drive assembly 122 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.

[0059] The specific structure of the battery cell gripper 121 can be designed according to actual needs. For example, the battery cell gripper 121 can adopt a finger cylinder or other suitable structure.

[0060] The connection method between the lifting drive assembly 122, the rotation drive assembly 123, and the cell clamp 121 can be designed according to actual needs. For example, in this embodiment, the lifting drive assembly 122 is driven to connect with the fixed base 1231, and the cell clamp 121 is set on the rotating base. The lifting drive assembly 122 drives the fixed base 1231 to rise and fall, thereby realizing the lifting and falling of the rotation drive assembly 123, and thus driving the cell clamp 121 to rise and fall. Alternatively, in other embodiments, the lifting drive assembly 122 is set on the rotating base and driven to connect with the cell clamp 121. The rotating base drives the lifting drive assembly 122 and the cell clamp 121 to rotate together, while the lifting drive assembly 122 directly drives the cell clamp 121 to rise and fall.

[0061] In some optional embodiments, the cell rotation mechanism 120 includes a plurality of cell grippers 121 arranged sequentially along the conveying direction of the cell conveying mechanism 50. The plurality of cell grippers 121 can simultaneously grip a plurality of processed cells 60, thereby enabling the cell rotation mechanism 120 to move and adjust the angle of the plurality of cell grippers 121 at one time.

[0062] Please see Figure 5 In some optional embodiments, the collector welding device 10 further includes a cell alignment mechanism 140. The cell alignment mechanism 140, the first cell flipping welding mechanism 110, the cell rotating mechanism 120, and the second cell flipping welding mechanism 130 are arranged sequentially along the conveying direction of the cell conveying mechanism 50. The cell alignment mechanism 140 includes two alignment clamps 141 and a clamp drive assembly 142. The two alignment clamps 141 are respectively disposed on both sides of the cell conveying mechanism 50, and the clamp drive assembly 142 is connected to the two alignment clamps 141. The clamping plates 141 are driven to connect. The two centering clamping plates 141 move closer and further away from each other under the drive of the clamping plate driving assembly 142. The two centering clamping plates 141 move closer to each other under the drive of the clamping plate driving assembly 142, so that the two centering clamping plates 141 can clamp the processing battery cell 60 located on the battery cell conveying mechanism 50, so that the processing battery cell 60 is clamped and positioned, thereby determining the position of the processing battery cell 60 relative to the battery cell conveying mechanism 50. Then the two centering clamping plates 141 move away from each other, thereby releasing the processing battery cell 60.

[0063] The specific structure of the clamping plate drive assembly 142 can be designed according to actual needs. For example, the clamping plate drive assembly 142 includes two drive assemblies, which are connected to the centering clamping plate 141. 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.

[0064] Please see Figures 6 to 8 In some optional embodiments, the first cell flipping welding mechanism 110 and the second cell flipping welding mechanism 130 both include a cell lifting assembly 1110, a cell lifting assembly 1120, a current collector positioning seat 1130, a flipping clamping assembly 1140 and a welding assembly 1150.

[0065] The cell lifting assembly 1110 is used to drive the processing cell 60 located on the cell conveying mechanism 50 to rise and fall;

[0066] The cell lifting assembly 1120 is arranged on one side of the cell lifting assembly 1110;

[0067] The current collector positioning seat 1130 is positioned above the cell lifting assembly 1120;

[0068] The flipping clamping assembly 1140 includes a flipping drive module 1141 and a plurality of battery cell clamping modules 1142 arranged sequentially along the conveying direction of the battery cell conveying mechanism 50. The flipping drive module 1141 is driven to connect with the battery cell clamping modules 1142. Under the drive of the flipping drive module 1141, the battery cell clamping modules 1142 rotate downward to a first position located at the top of the battery cell lifting assembly 1110 and rotate upward to a second position located between the battery cell lifting assembly 1120 and the current collector positioning seat 1130.

[0069] The welding assembly 1150 is positioned above the manifold positioning seat 1130.

[0070] The working principle of the first cell flipping and welding mechanism 110 and the second cell flipping and welding mechanism 130 is the same. The working principle of the first cell flipping and welding mechanism 110 is explained below:

[0071] When the cell clamping module 1142 is in the first position, the cell lifting assembly 1110 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 1142. Then, the cell clamping module 1142 clamps the processing cell 60. The flipping drive module 1141 drives the cell clamping module 1142 to rotate upward to the second position. Then, the cell lifting assembly 1120 pushes the processing cell 60 on the cell clamping module 1142 upward, so that the processing cell 60... The top electrode moves toward the processing current collector on the current collector positioning seat 1130. Then, the welding assembly 1150 welds the processing current collector to the electrode of the processing cell 60. Next, the cell lifting assembly 1120 descends, and the flipping drive module 1141 drives the cell clamping module 1142 to rotate back to the first position. Then, the cell clamping module 1142 releases the processing cell 60, so that the processing cell 60 is placed on the cell lifting assembly 1110. Then, the cell lifting assembly 1110 descends to place the processing cell 60 back onto the cell conveying mechanism 50.

[0072] 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.

[0073] The specific structure of the flip drive module 1141 can be designed according to actual needs. For example, the flip drive module 1141 can adopt a flip drive motor.

[0074] Please see Figure 9 In some optional embodiments, the cell lifting assembly 1110 includes a first support base 1111, a second support base 1112, and a lifting drive module 1113. A conveying clearance space 1114 for the cell conveying mechanism 50 is formed between the first support base 1111 and the second support base 1112. The lifting drive module 1113 is drivenly connected to the first support base 1111 and the second support base 1112. The cell conveying mechanism 50 passes through the conveying clearance space 1114. The first support base 1111 and the second support base 1112 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 1111 and the second support base 1112 rise under the drive of the lifting drive module 1113, the first support base 1111 and the second support base 1112 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 1111 and the second support base 1112 fall, the processing cell 60 can be placed on the cell conveying mechanism 50.

[0075] The specific structure of the lifting drive module 1113 can be designed according to actual needs. For example, the lifting drive module 1113 can use an electric cylinder, a pneumatic cylinder, a hydraulic cylinder, etc., and is not limited to this example.

[0076] In some alternative embodiments, the first support 1111 and the second support 1112 are connected by a connecting beam 1115. The lifting drive module 1113 is arranged on one side of the conveying clearance space 1114 and is drivenly connected to the first support 1111. The connecting beam 1115 can connect the first support 1111 and the second support 1112 together, and the lifting drive module 1113 only needs to drive the first support 1111 to rise and fall, which can simultaneously drive the first support 1111 and the second support 1112 to rise and fall together.

[0077] In some optional embodiments, the first support 1111 and the second support 1112 are provided with a plurality of limiting grooves 11111. The positions of the limiting grooves 11111 of the first support 1111 and the limiting grooves 11111 of the second support 1112 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 11111 of the first support 1111 and the limiting grooves 11111 of the second support 1112. The limiting grooves 11111 can prevent the processed battery cells 60 from shaking relative to the first support 1111 and the second support 1112.

[0078] In some optional embodiments, the cell lifting assembly 1120 includes a plurality of lifting rods 1121 and a lifting drive module 1122. The lifting rods 1121 are arranged on the collector plate positioning seat 1130. The lifting drive module 1122 is drivenly connected to the plurality of lifting rods 1121. When the cell clamping module 1142 is in the second position, the lifting rods 1121 are located below the cell clamping module 1142 and abut against the bottom of the processed cell 60. When the lifting rods 1121 rise, they can push the processed cell 60 to rise. When the lifting rods 1121 fall, the processed cell 60 falls accordingly. It should be noted that when the lifting rods 1121 fall, the cell clamping module 1142 can slightly loosen the processed cell 60, so that the processed cell 60 can fall by gravity.

[0079] The specific structure of the lifting drive module 1122 can be designed according to actual needs. For example, the lifting drive module 1113 can use electric cylinders, pneumatic cylinders, hydraulic cylinders, etc., without being limited to this example.

[0080] The specific structure of the cell clamping module 1142 can be designed according to actual needs. For example, the cell clamping module 1142 can use a finger cylinder. In this embodiment, the cell clamping module 1142 includes a clamping drive module 11421 and two clamping plates 11422. The two clamping plates 11422 clamp and cooperate under the drive of the clamping drive module 11421, and the two clamping plates 11422 cooperate to clamp the processed cell 60. When the cell clamping module 1142 is in the second position, the lifting rods 1121 of the cell lifting assembly 1120 push the processed cell 60 upward one by one, thereby driving the processed cell 60 to rise relative to the two clamping plates 11422. After the current collector is welded, the lifting rods 1121 descend, and the processed cell 60 descends under the action of gravity. The clamping plates 11422 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 1111 and the second support base 1112 lift the sub-processed battery cell 60, the clamping plate 11422 can extend between the first support base 1111 and the second support base 1112 to clamp the sub-processed battery cell 60.

[0081] The specific structure of the clamping drive module 11421 can be designed according to actual needs. For example, the lifting drive module 1113 can be an electric cylinder, a pneumatic cylinder, a hydraulic cylinder, etc., and is not limited to this example.

[0082] The specific structure of the welding assembly 1150 can be designed according to actual needs. For example, in some optional embodiments, the welding assembly 1150 includes a two-axis translation drive module 1151 and a laser module 1152. The laser module 1152 is arranged on the top of the collector plate positioning seat 1130. The two-axis translation drive module 1151 is drivenly connected to the laser module 1152. The laser module 1152 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 1151. The two-axis translation drive module 1151 may include a first electric cylinder and a second electric cylinder. The first electric cylinder drives the second electric cylinder to move up and down, and the second electric cylinder drives the laser module 1152 to move along the conveying direction of the cell conveying mechanism 50. Of course, the structure of the two-axis translation drive module 1151 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.

[0083] Please see Figure 10 and Figure 11In some optional embodiments, the top of the current collector positioning seat 1130 is provided with a plurality of positioning through slots 1131 arranged sequentially along the conveying direction of the cell conveying mechanism 50. The positioning through slots 1131 are used to position and cooperate with the processing current collector. When the cell clamping module 1142 is in the second position, the cell clamping module 1142 is located below the positioning through slot 1131. After the lifting rod 1121 lifts the processing cell 60, the processing cell 60 moves to the positioning through slot 1131. The top electrode of the processing cell 60 extends into the positioning through slot 1131, so that the processing current collector contacts the processing cell 60, and then the welding operation can be performed.

[0084] The first cell flipping welding mechanism 110 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 1132 is formed on one side of the positioning through groove 1131 of the first cell flipping welding mechanism 110. The tab of the current collector is positioned by the tab positioning groove 1132, 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.

[0085] Please see Figures 12 to 16 The specific structure of the battery cell tab bending mechanism 30 can be designed according to actual needs. For example, in this embodiment, the battery cell tab bending mechanism 30 includes: a battery cell support assembly 310, a battery cell rotation assembly 320, and multiple tab bending assemblies 330.

[0086] The battery cell support assembly 310 includes a first battery cell lifting seat 311, a second battery cell lifting seat 312, and a battery cell lifting module 313. A clearance conveying space 314 is formed between the first battery cell lifting seat 311 and the second battery cell lifting seat 312, through which the battery cell conveying mechanism 50 passes. Multiple support wheels 3111 are rotatably arranged on both the first battery cell lifting seat 311 and the second battery cell lifting seat 312. The multiple support wheels 3111 are arranged sequentially along the extension direction of the clearance conveying space 314. A support space 3112 is formed between two adjacent support wheels 3111 on the first battery cell lifting seat 311 and between two adjacent support wheels 3111 on the second battery cell lifting seat 312.

[0087] The cell rotation assembly 320 includes a mounting base 321, a wheel drive module 322 and multiple drive wheels 323. The wheel drive module 322 is drivenly connected to the multiple drive wheels 323. The drive wheels 323 are arranged above the clearance conveying space 314. The multiple drive wheels 323 are arranged sequentially along the extension direction of the clearance conveying space 314.

[0088] Multiple tab bending assemblies 330 are correspondingly arranged on one side of multiple support spaces 3112. Each tab bending assembly 330 includes a tab detection module 331, a first tab bending member 332, and a first bending drive module 333. The tab detection module 331 is correspondingly arranged on one side of the support space 3112 of the first cell lifting seat 311. The first bending drive module 333 is drivenly connected to the first tab bending member 332. The first tab bending member 332 is correspondingly arranged on one side of the support space 3112 of the first cell lifting seat 311. The first tab bending member 332 moves back and forth from the first cell lifting seat 311 to the second cell lifting seat 312 under the drive of the first bending drive module 333.

[0089] Please see Figure 17 The working principle of the battery cell tab bending mechanism 30 according to one embodiment of the present invention will be explained below:

[0090] The cell conveying mechanism 50 passes through the clearance conveying space 314. The processing cell 60 is conveyed horizontally by the cell conveying mechanism 50 to the space between the first cell lifting seat 311 and the second cell lifting seat 312. The positive terminal of the processing cell 60 faces the first cell lifting seat 311, and both ends of the processing cell 60 extend from both sides of the cell conveying mechanism 50. The cell lifting module 313 drives the first cell lifting seat 311 and the second cell lifting seat 312 to rise, and the processing cell... The portions of the battery cell 60 extending from both sides of the battery cell conveying mechanism 50 will correspondingly enter the support space 3112. The two support wheels 3111 on the first battery cell lifting seat 311 and the two support wheels 3111 on the second battery cell lifting seat 312 jointly support a processing battery cell 60. The first battery cell lifting seat 311 and the second battery cell lifting seat 312 rise until the top of the processing battery cell 60 abuts against the bottom of the power wheel 323. At this time, the power wheel 323 contacts the processing battery cell 60. Then, the wheel drive module 322 drives the power wheel 323 to rotate. The friction between the power wheel 323 and the processing battery cell 60 will drive the processing battery cell 60 to rotate. Since the support wheel 3111 can rotate, the friction between the support wheel 3111 and the processing battery cell 60 is rolling friction, so the processing battery cell 60 can rotate relatively smoothly. After the processing battery cell 60 rotates to a specific position, the tab of the current collector of the positive electrode of the processing battery cell 60 will trigger the electrode. After the ear detection module 331 detects the ear, the first ear bending member 332 moves under the drive of the first bending drive module 333. Since the ear is a radial extension relative to the processed battery cell 60, the ear protrudes from the processed battery cell 60. The first ear bending member 332 moves along the axial direction of the processed battery cell 60. As the first ear bending member 332 moves, it will drive the ear to bend axially toward the processed battery cell 60, so that the ear extends axially.

[0091] The specific structure of the cell lifting module 313 can be designed according to actual needs. For example, the cell lifting module 313 can be a screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc., and is not limited to this example.

[0092] The specific structure of the first bending drive module 333 can be designed according to actual needs. For example, the first bending drive module 333 can be a screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc., and is not limited to this example.

[0093] The specific structure of the wheel drive module 322 can be designed according to actual needs. For example, the wheel drive module 322 includes multiple wheel drive motors, which are connected to the drive wheels 323.

[0094] In some optional embodiments, the cell support assembly 310 further includes a first cell positioning seat 315, a second cell positioning seat 316, a first positioning drive module 317, and a second positioning drive module 318. The first cell positioning seat 315 is movably disposed on the first cell lifting seat 311 and is located on the side of the first cell lifting seat 311 away from the second cell lifting seat 312. The first positioning drive module 317 is drivenly connected to the first cell positioning seat 315. The first cell positioning seat 315 is positioned at the first cell positioning seat 316. Driven by the drive module 317, the support wheel 3111 of the first cell lifting seat 311 moves closer to and further away from the support wheel 3111 of the second cell lifting seat 312. The second cell positioning seat 316 is movably mounted on the second cell lifting seat 312 and is located on the side of the second cell lifting seat 312 away from the support wheel 3111 of the first cell lifting seat 311. The second positioning drive module 318 is driven to connect with the second cell positioning seat 316. Driven by the second positioning drive module 318, the second cell positioning seat 316 moves closer to and further away from the support wheel 3111 of the second cell lifting seat 312. After the cell lifting module 313 drives the first cell lifting seat 311 and the second cell lifting seat 312 to rise, the support wheel 3111 supports the processed cell 60. Then, the first cell positioning seat 315 and the second cell positioning seat 316 move toward the support wheel 3111. The first cell positioning seat 315 abuts against the positive terminal of the processed cell 60, so that the current collector on the positive terminal of the processed cell 60 is pressed. The second cell positioning seat 316 abuts against the negative terminal of the processed cell 60. The support wheel 3111 supports the processed cell 60, and the first cell positioning seat 315 and the second cell positioning seat 316 cooperate to restrict the two sides of the processed cell 60. Then, the power wheel 323 presses the processed cell 60 downward, so that the processed cell 60 is restricted vertically and laterally, improving the stability of the restriction.

[0095] The specific structure of the first positioning drive module 317 and the second positioning drive module 318 can be designed according to actual needs. For example, the first positioning drive module 317 and the second positioning drive module 318 can be a lead screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc., and are not limited to this example.

[0096] In some optional embodiments, a plurality of first positioning elements 3151 are provided on the first cell positioning base 315, and the plurality of first positioning elements 3151 are correspondingly arranged on one side of the support space 3112. A plurality of second positioning elements 3161 are rotatably provided on the second cell positioning base 316, and the plurality of second positioning elements 3161 are correspondingly arranged on one side of the support space 3112. When the first cell positioning base 315 moves toward the support wheel 3111, the first positioning elements 3151 abut against the processed cell in the support space 3112. When the second cell positioning seat 316 moves toward the support wheel 3111, the second positioning member 3161 abuts against the negative end of the processed cell 60 in the support space 3112. The first positioning member 3151 abuts against the positive end of the processed cell 60, and the second positioning member 3161 abuts against the negative end of the processed cell 60. The friction between the second positioning member 3161 and the processed cell 60 causes the second positioning member 3161 to rotate with the processed cell 60, thereby improving the positional stability of the processed cell 60.

[0097] In some optional embodiments, the tab bending assembly 330 further includes a second tab bending member 334 and a second bending drive module 335. The second tab bending member 334 is vertically and vertically disposed above the first cell positioning seat 315. The second bending drive module 335 is drivenly connected to the second tab bending member 334. After the first tab bending member 332 moves, it will drive the tab to bend axially toward the processed cell 60. Then the second tab bending member 334 will descend to press the tab onto the first cell positioning seat 315, so that the tab is stably straightened.

[0098] The specific structure of the second bending drive module 335 can be designed according to actual needs. For example, the second bending drive module 335 can be a screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc., and is not limited to this example.

[0099] Please see Figures 18 to 19In some optional embodiments, the second electrode bending member 334 is positioned above the first positioning member 3151. The first positioning member 3151 has a support portion 3152. After the second electrode bending member 334 descends, it drives the electrode to press against the support portion 3152. When the electrode is bent by the first electrode bending member 332, it also bends towards the support portion 3152. Since the second electrode bending member 334 cannot completely straighten the electrode, it descends under the drive of the second bending drive module 335, pressing the electrode against the support portion 3152, thus stably straightening the electrode. In this embodiment, the moving direction of the first electrode bending member 332 and the moving direction of the second electrode bending member 334 are perpendicular to each other.

[0100] In some optional embodiments, both the first cell lifting seat 311 and the second cell lifting seat 312 are provided with movable tracks 3113. The first cell positioning seat 315 is slidably connected to the movable track 3113 of the first cell lifting seat 311, and the second cell positioning seat 316 is slidably connected to the movable track 3113 of the second cell lifting seat 312. The first cell lifting seat 311 and the second cell lifting seat 312 are moved stably through the movable tracks 3113.

[0101] In some alternative embodiments, a friction layer 324 is provided on the outer peripheral surface of the drive wheel 323. The friction layer 324 can be a rubber layer or a silicone layer, etc. The friction layer 324 can increase the friction between the drive wheel 323 and the processed battery cell 60, thereby ensuring that the drive wheel 323 can drive the processed battery cell 60 to rotate, so that the processed battery cell 60 can rotate to a suitable angle.

[0102] In some optional embodiments, the first cell lifting seat 311 and the second cell lifting seat 312 are connected to each other by a connector 319, and the cell lifting module 313 is driven to be connected to the first cell lifting seat 311 or the second cell lifting seat 312, so that the cell lifting module 313 can be arranged on one side of the conveying space 314, so that the cell lifting module 313 can simultaneously drive the first cell lifting seat 311 and the second cell lifting seat 312 to rise and fall.

[0103] Please see Figure 20 Two collector plate feeding mechanisms 20 respectively transport the processing collector plates to the collector plate positioning seat 1130 of the first cell flipping and welding mechanism 110 and the collector plate positioning seat 1130 of the second cell flipping and welding mechanism 130. The specific structure of the collector plate feeding mechanism 20 can be designed according to actual needs. For example, in this embodiment, the collector plate feeding mechanism 20 includes a collector plate handling component 210, a collector plate storage component 220 and a collector plate transfer seat 230.

[0104] The collector plate storage components 220 of the two collector plate feeding mechanisms 20 are respectively arranged on one side of the collector plate positioning seat 1130 of the first cell flipping welding mechanism 110 and the second cell flipping welding mechanism 130. The collector plate transfer seat 230 is respectively arranged between the collector plate storage components 220 and the collector plate positioning seat 1130. The collector plate transport component 210 is used to transport the collector plates on the collector plate storage components 220 to the collector plate transfer seat 230 and the corresponding collector plate positioning seat 1130 in sequence.

[0105] The collector plate transport assembly 210 is used to sequentially transport the collector plates on the collector plate storage assembly 220 to the collector plate transfer seat 230 and the corresponding collector plate positioning seat 1130. The collector plate transport assembly 210 includes a two-axis transport module 211, a movable seat 212, a plurality of suction heads 213 and a plurality of welding suction plates 214. The two-axis transport module 211 is driven to the movable seat 212. The suction heads 213 and the welding suction plates 214 are both set on the movable seat 212. The movable seat 212 can move to the first transport position and the second transport position in the direction from the collector plate storage assembly 220 to the collector plate positioning seat 1130 under the drive of the two-axis transport module 211, and can also be raised and lowered under the drive of the two-axis transport module 211. The suction heads 213 and the plurality of welding suction plates 214 are all connected to a negative pressure generating device. After the negative pressure generating device is started, a negative pressure for adsorbing the processing collector plates can be formed at the suction heads 213 and the plurality of welding suction plates 214. The welding assembly 1150 welds the fabricated current collector on the current collector positioning seat 1130 to the electrode of the fabricated cell 60.

[0106] When the movable seat 212 is in the first transport position, the adsorption head 213 is located at the collection plate storage component 220, and the welding adsorption plate 214 is located at the collection plate transfer seat 230.

[0107] When the movable seat 212 is in the second transport position, the adsorption head 213 is located at the collector plate transfer seat 230, and the welding adsorption plate 214 is located at the collector plate positioning seat 1130.

[0108] The working principle of the collecting tray feeding mechanism 20 according to one embodiment of this utility model is described below:

[0109] The two-axis transport module 211 drives the movable seat 212 to move to the first transport position, and then drives the movable seat 212 to descend, so that the adsorption head 213 adsorbs the processing collection plate on the collection plate storage component 220, and the welding adsorption plate 214 adsorbs the processing collection plate on the collection plate transfer seat 230.

[0110] Subsequently, the two-axis transport module 211 drives the movable seat 212 to rise, then drives the movable seat 212 to move to the second transport position, and then drives the movable seat 212 to descend. Then, the adsorption head 213 releases its adsorption on the processing collection plate, so that the processing collection plate on the adsorption head 213 is placed on the collection plate transfer seat 230, while the welding adsorption plate 214 releases its adsorption on the processing collection plate, so that the processing collection plate on the welding adsorption plate 214 is placed on the collection plate positioning seat 1130. This cycle is repeated, so that the processing collection plate on the collection plate storage component 220 can be continuously transported to the collection plate positioning seat 1130.

[0111] The design of the transfer seat 230 in the collector tray reduces the distance that the movable seat 212 moves each time, effectively speeding up the production cycle.

[0112] The specific structure of the two-axis conveying module 211 can be designed according to actual needs. For example, in one embodiment, the two-axis conveying module 211 includes a lateral translation module and a vertical translation module. The lateral translation module is driven to connect with the vertical translation module, and the vertical translation module is driven to connect with the movable seat 212. The lateral translation module drives the vertical translation module and the movable seat 212 to move back and forth together in the direction from the collector storage component 220 to the collector positioning seat 1130. The lateral translation module drives the movable seat 212 to rise and fall. The lateral translation module and the vertical translation module can be a 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, etc.

[0113] In some optional embodiments, the manifold transport assembly 210 includes multiple adsorption heads 213 and multiple welding adsorption plates 214. The multiple adsorption heads 213 are arranged side by side. The manifold transport assembly 210 can simultaneously adsorb multiple processing manifolds through the multiple adsorption heads 213 and the multiple welding adsorption plates 214. The movable seat 212 can transport multiple processing manifolds at the same time with a single movement, which improves the transport efficiency.

[0114] Please see Figure 21In some optional embodiments, the collector tray transfer base 230 is provided with a plurality of transfer positioning grooves 231 for positioning and cooperating with the processing collector tray. The processing collector tray is positioned by the transfer positioning grooves 231. It should be noted that the transfer positioning grooves 231 need to be adapted to the structure of the adsorption head 213 and the welding adsorption plate 214, so that the adsorption head 213 can place the processing collector tray in the transfer positioning groove 231 and the welding adsorption plate 214 can adsorb the processing collector tray in the transfer positioning groove 231. When the collector tray conveying assembly 210 includes multiple adsorption heads 213 and multiple welding adsorption plates 214, the collector tray transfer base 230 is provided with multiple transfer positioning grooves 231 arranged side by side.

[0115] Please see Figure 22 and Figure 23 In some optional embodiments, the collector tray transport assembly 210 includes a support 221 and a collector tray lifting module 222. The support 221 is provided with a plurality of collector tray storage channels 2211. The top and bottom of the collector tray storage channels 2211 are respectively formed with a top port and a bottom port. The collector tray lifting module 222 is located below the collector tray storage channels 2211. A part of the collector tray lifting module 222 extends into the collector tray storage channel 2211 from the bottom port. When the movable seat 212 is in the first transport position, the suction head 213 is located at the top port of the collector tray storage channel 2211. Multiple processing collection trays can be stored in the collection tray storage channel 2211. The multiple processing collection trays in the collection tray storage channel 2211 are stacked sequentially from top to bottom. The suction head 213 can stop above the top port, stop at the top port, or extend into the collection tray storage channel 2211 from the top port. Then, the collection tray lifting module 222 drives the processing collection tray in the collection tray storage channel 2211 to rise, so that the processing collection tray at the highest point in the collection tray storage channel 2211 can contact the suction head 213.

[0116] It should be noted that since the welding of the manifolds is all done by laser, the structure of the welding adsorption plate 214 needs to be designed to avoid the laser. However, due to structural limitations, the welding adsorption plate 214 cannot adsorb the manifolds on the manifold storage component 220. Usually, an adsorption head 213 corresponding to the manifold storage component 220 is needed to adsorb the manifolds on the manifold storage component 220. Through the design of the manifold transfer seat 230, after the adsorption head 213 adsorbs and moves the manifolds on the manifold storage component 220 to the manifold transfer seat 230, the welding adsorption plate 214 can adsorb the manifolds from the manifold transfer seat 230. Therefore, it effectively avoids the situation where the welding adsorption plate 214 cannot adsorb the manifolds due to the incompatibility between the structure of the welding adsorption plate 214 and the manifold storage component 220. Especially when the adsorption head 213 needs to extend into the manifold storage channel 2211 to adsorb and replace the manifolds, the welding adsorption plate 214 cannot extend into the manifold storage channel 2211 due to structural limitations.

[0117] In some optional embodiments, the manifold transport assembly 210 further includes an adsorption lifting module 215, which is driven to connect with the adsorption head 213. The adsorption head 213 can be raised and lowered under the drive of the adsorption lifting module 215. When the movable seat 212 is in the first transport position, after the movable seat 212 is lowered, the welding adsorption plate 214 adsorbs the manifold transfer seat 230. At this time, the adsorption lifting module 215 needs to drive the adsorption head 213 to a suitable position so that the adsorption head 213 can contact the manifold storage channel 2211. After the adsorption head 213 adsorbs the manifold, the adsorption lifting module 215 drives the adsorption head 213 to rise to a suitable position so that the manifold can be placed on the manifold transfer seat 230 in the future.

[0118] The specific structure of the adsorption lifting module 215 can be designed according to actual needs. For example, the adsorption lifting module 215 can be a screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module.

[0119] The specific structure of the collector plate lifting module 222 can be designed according to actual needs. For example, in some optional embodiments, the collector plate lifting module 222 includes several push rods 2221 and a push rod 2221 driving module. The push rods 2221 are located below the collector plate storage channel 2211. The push rod 2221 driving module is driven to the push rods 2221. The push rods 2221 can extend into the bottom port under the drive of the push rod 2221 driving module. The push rods 2221 can stably push the processing collector plate in the collector plate storage channel 2211 to rise.

[0120] The specific structure of the push rod 2221 drive module can be designed according to actual needs. For example, the push rod 2221 drive module can be a lead screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module.

[0121] In some alternative embodiments, the support 221 has multiple collector tray storage channels 2211 arranged side by side to accommodate more processing collector trays. When the collector tray handling assembly 210 includes multiple adsorption heads 213 and multiple welding adsorption trays 214, the adsorption heads 213 can adsorb the processing collector trays in the collector tray storage channels 2211.

[0122] In some optional embodiments, the support 221 is provided with a first storage seat 2212, a second storage seat 2213 and a moving drive module 2214. The first storage seat 2212 and the second storage seat 2213 are movably mounted on the support 221. Both the first storage seat 2212 and the second storage seat 2213 are provided with a collection tray storage channel 2211. The moving drive module 2214 is driven to the first storage seat 2212 and the second storage seat 2213. Under the drive of the moving drive module 2214, when the movable seat 212 is in the first transport position, the first storage seat 2212 or the second storage seat 2213 is correspondingly located below the suction head 213. In this embodiment, both the first storage base 2212 and the second storage base 2213 are provided with the same number of collector tray storage channels 2211 as the suction head 213. When the movable base 212 is in the first transport position, the first storage base 2212 is initially positioned below the suction head 213. The suction head 213 picks up the processing collector trays in the collector tray storage channels 2211 on the first storage base 2212. After all the processing collector trays in the collector tray storage channels 2211 on the first storage base 2212 have been transported away, the movement drive module 2214 moves the first storage base 2212 away and moves the second storage base 2213 away. The storage seat 2213 moves to a position corresponding to the position below the suction head 213. Then, the suction head 213 picks up the processing collection trays in the collection tray storage channel 2211 on the second storage seat 2213. At this time, the collection tray storage channel 2211 of the first storage seat 2212 can be filled with processing collection trays. After all the processing collection trays in the collection tray storage channel 2211 on the second storage seat 2213 have been removed, the first storage seat 2212 is moved back to the position corresponding to the position below the suction head 213. In this way, there is no need to stop the production operation to fill the processing collection trays, ensuring continuous production.

[0123] The specific structure of the mobile drive module 2214 can be designed according to actual needs. For example, the mobile drive module 2214 can be a lead screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc. In this case, the mobile drive module 2214 drives the first storage seat 2212 and the second storage seat 2213 to translate. Of course, the mobile drive module 2214 can also achieve position switching by driving the first storage seat 2212 and the second storage seat 2213 to rotate. For example, in this embodiment, the mobile drive module 2214 is a geared motor, which is drivenly connected to the first storage seat 2212 and the second storage seat 2213 to drive the first storage seat 2212 and the second storage seat 2213 to rotate around the geared motor; in addition, the geared motor can be drivenly connected to a turntable, and the first storage seat 2212 and the second storage seat 2213 are arranged on the turntable.

[0124] The principle and structure of the cell coating mechanism 40 are well known to those skilled in the art and will not be described in detail here. The cell conveying mechanism 50 can finally convey the processed cell 60 to the cell coating mechanism 40. The cell coating mechanism 40 coats the processed cell 60 with glue. The cell conveying mechanism 50 can also pass through the processed cell 60. After the processed cell 60 is coated with glue, the cell conveying mechanism 50 can also convey the processed cell 60 to the next process.

[0125] 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.
