Description

Technical Field

[0001] This invention relates to the field of sodium electrode processing technology for batteries, and particularly to a sodium electrode processing apparatus for sodium-ion batteries. Background Technology

[0002] The sodium-ion battery electrode welding processing device is a specialized piece of equipment used in the manufacture of sodium-ion batteries. Its main function is to weld the positive and negative electrode plates (usually sodium plates) of sodium-ion batteries to other parts of the battery (such as electrolytes, separators, etc.) to complete the battery assembly process. The equipment is integrated with the workbench. During use, the batteries are arranged manually and the electrode plates are placed on top of the battery pack. The assembled components are then placed under the welding head, and spot welding is performed between the battery electrodes and the electrode plates using a foot pedal.

[0003] The welding equipment used in the existing sodium-ion battery processing requires manual stacking of the batteries, with the positive and negative electrodes connected before welding can be performed. This requires workers to put in more effort to stack the sodium-ion batteries to avoid errors, thus limiting production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a sodium-ion battery sodium electrode processing device. This device features an alternating rotation of the sodium-ion battery positions via a positive and negative electrode adjustment assembly, thereby connecting the positive electrode of the stacked sodium-ion battery to the negative electrodes positioned above and below. This cyclical process achieves alternating stacking to form a series battery pack. The device also includes a fully automated process for sodium-ion battery electrode gripping, orientation, stacking, and welding, significantly improving production efficiency. It boasts high reliability and a stable operating rhythm. The suction cup gripping mechanism offers strong adaptability and can handle electrode sheets of different sizes.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sodium sheet electrode processing device for sodium-ion batteries, comprising a working platform, the top surface of which is divided into an adjustment area, a welding area and a welding area, wherein a positive and negative electrode adjustment assembly is provided on the adjustment area and a welding head is provided on the welding area;

[0006] The positive and negative electrode adjustment assembly is used to stack sodium-ion battery electrodes sequentially on the area to be welded, wherein the positive electrode of the stacked sodium-ion battery electrode is connected to the negative electrode of the adjacent sodium-ion battery electrode.

[0007] The positive and negative electrode adjustment assembly includes an adjustment frame, a suction cup component, and a rack. The adjustment frame is equipped with a suction cup component that slides up and down. The rotating shaft fixed to the suction cup component rotates around the adjustment frame, and a gear ring is fixed to the outer wall of the rotating shaft.

[0008] The rack is driven by a drive cylinder on the working platform, which is used to control the rack to engage or disengage from the gear ring;

[0009] The adjustment frame moves back and forth between the adjustment area and the welding area via the slide rail on the work platform. One round trip of the adjustment frame is one cycle. The movement of the adjustment frame from the adjustment area to the welding area is the feeding action, and the return from the welding area to the adjustment area is the reset action. During one cycle, the drive cylinder keeps the drive rack away from the movement path of the gear ring for the rack and gear ring to disengage. In the next cycle, during the feeding action, the drive rack moves onto the movement path of the gear ring for the gear ring and rack to engage. After the gear ring passes the rack, it drives the suction cup to rotate synchronously to change the positive and negative polarity of the sodium-ion battery electrode, so that the positive and negative polarities of the stacked sodium-ion battery electrode are connected.

[0010] The welding head, with adjustable height, is used for welding the positive and negative electrodes after they have been stacked.

[0011] As an optional implementation, the suction cup component includes a suction cup, an air path support, and a main air pipe. The bottom of the air path support is connected to several suction cups, and the interior of the main air pipe is connected to several suction cups through the inner cavity of the air path support.

[0012] The top of the main air tube is inserted into the through hole at the bottom of the rotating shaft, where the main air tube and the rotating shaft rotate synchronously.

[0013] As an optional implementation, the adjusting frame is also equipped with a cylinder, the piston rod of the cylinder is connected to a rotating ring fitted on the outside of the main air pipe, wherein the rotating ring moves up and down synchronously with the main air pipe and can rotate around the main air pipe.

[0014] As an optional implementation, the rotating shaft is connected to a gas hose on the outer wall above the gear ring. The gas hose is connected to the through hole and connected to the air pump of the adjustment frame. The gas hose, rotating shaft, main air pipe and air path support form an air path channel. The air pump drives the suction cup to pick up or put down the sodium-ion battery cell through the air path channel.

[0015] As an optional implementation, the drive cylinder is connected to a rack via a piston rod, the rack is supported by an adjusting frame, and the drive cylinder is controlled by a drive assembly on a working platform.

[0016] As an optional implementation, the drive assembly includes a hydraulic pump and a pipeline. The hydraulic pump is connected to the drive cylinder through the pipeline and is used to change the position of the piston rod to drive the rack to reciprocate.

[0017] As an optional implementation, the drive assembly includes a first baffle, a second baffle, a limiting plate, a slotted limiting frame, a limiting rod, a top plate, and a drive tube. The limiting plate is mounted on the working platform, the first baffle is fixed on the limiting plate, and the second baffle slides back and forth along the slide rail on the limiting plate. The first baffle and the second baffle are connected by a spring.

[0018] The limiting plate is also provided with a locking groove. The bottom end of the limiting rod that slides at the bottom of the second baffle is inserted into the locking groove. The slotted limiting frame and the bracket on the limiting plate are connected by a spring. The top plate is fixed on the adjusting frame.

[0019] As an optional implementation, the slotted limiting frame is provided with an inclined slope at the bottom corner facing the top plate. The top plate pushes the slotted limiting frame upward through the inclined slope to offset it from the limiting rod.

[0020] As an optional implementation, the locking groove is composed of an inclined groove one, a V-shaped groove and an inclined groove two that are interconnected. The inclined groove one and the inclined groove two are respectively arranged on both sides of the V-shaped groove, and an arc-shaped notch for accommodating the limiting rod is provided at the included angle of the V-shaped groove.

[0021] As an optional implementation, the slotted limit frame has a slot for inserting a limit rod, and the slotted limit frame is used to hold the limit rod located in the arc-shaped notch.

[0022] The technical effects and advantages of this invention are as follows:

[0023] By alternating the positions of sodium-ion batteries through a positive and negative electrode adjustment assembly, the positive electrode of the stacked sodium-ion batteries is connected to the negative electrode above and below. This cycle is repeated, achieving alternating stacking of "one upright, one reversed" to form a series battery pack. This fully automates the process of sodium-ion battery electrode gripping, orientation, stacking, and welding, significantly improving production efficiency. The purely mechanical structure implements the action logic, ensuring high reliability and stable operation. The suction cup gripping mechanism is highly adaptable and can handle electrode sheets of different sizes. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1:

[0035] See Figures 1-3 A sodium-ion battery sodium sheet electrode processing device includes a working platform 1, the top surface of which is divided into an adjustment area, a welding area and a welding area. A positive and negative electrode adjustment assembly 2 is provided on the adjustment area, and a welding head 3 is provided on the welding area.

[0036] Specifically, the adjustment area, the area to be welded, and the welding area are distributed sequentially on the work platform 1. The positive and negative electrode adjustment assembly 2 is used to stack sodium-ion battery electrodes sequentially on the area to be welded, wherein the positive electrode of the stacked sodium-ion battery electrode is connected to the negative electrode of the adjacent sodium-ion battery electrode.

[0037] When sodium-ion batteries are moved to the working platform 1 by the conveyor belt, the sodium-ion batteries are placed in the same order. This means that during subsequent welding, the sodium-ion batteries need to be stacked and then the electrodes of the stacked batteries are welded by the welding head 3. In order to ensure that the positive electrode is connected to the negative electrode above and below during welding, the position of the sodium-ion batteries is rotated alternately by the positive and negative electrode adjustment assembly 2. This ensures that the positive electrode of the stacked sodium-ion batteries is connected to the negative electrode above and below, so as to ensure that the batteries are in series and form a battery pack.

[0038] The positive and negative pole adjustment assembly 2 includes an adjustment frame 21, a suction cup component 22 and a rack 23. The adjustment frame 21 is provided with a suction cup component 22 that slides up and down. The rotating shaft 24 fixed to the suction cup component 22 rotates around the adjustment frame 21. The outer wall of the rotating shaft 24 is fixed with a gear ring 25.

[0039] The rack 23 is pushed by the drive cylinder 11 on the working platform 1, which is used to control the rack 23 to engage or disengage from the gear ring 25;

[0040] The adjustment frame 21 moves back and forth between the adjustment area and the welding area via the slide rail on the working platform 1. One round trip of the adjustment frame 21 is one cycle. The movement of the adjustment frame 21 from the adjustment area to the welding area is a feeding action, and the return from the welding area to the adjustment area is a reset action. During one cycle, the drive cylinder 11 keeps the drive rack 23 away from the movement path of the gear ring 25 for the rack 23 and the gear ring 25 to disengage. During the feeding action of the next cycle, the drive rack 23 moves to the movement path of the gear ring 25 for the gear ring 25 and the rack 23 to engage. After the gear ring 25 passes the rack 23, it drives the suction cup 22 to rotate synchronously to change the positive and negative pole orientation of the sodium-ion battery electrode, so that the positive and negative poles of the stacked sodium-ion battery electrode are connected.

[0041] Welding head 3, with adjustable height, is used for welding the positive and negative electrodes after stacking.

[0042] The welding head 3 uses existing technology and is connected to the robotic arm. The robotic arm enables the welding head 3 to move to any position in three-dimensional space. The welding head 3 welds the sodium-ion battery electrodes after they are stacked.

[0043] The adjusting frame 21 is also equipped with a cylinder. The piston rod of the cylinder is connected to a rotating ring that is fitted on the outside of the main air pipe 223. The rotating ring moves up and down synchronously with the main air pipe 223 and can rotate around the main air pipe 223.

[0044] The bottom of the air passage support 222 is connected to several suction cups 221. The interior of the main air pipe 223 is connected to several suction cups 221 through the inner cavity of the air passage support 222. The top end of the main air pipe 223 is inserted into the through hole at the bottom of the rotating shaft 24. The main air pipe 223 and the rotating shaft 24 rotate synchronously.

[0045] Specifically, the cylinder can drive the rotating ring to rise or fall. The rotating ring is assembled from two ring bodies, upper and lower, by bolts. The opposite end faces of the upper and lower ring bodies are provided with ring grooves. A protrusion is fixed on the outer wall of the main air pipe 223. During assembly, first align the ring groove of the lower ring body with the bottom of the protrusion and put it on the protrusion. Then align the ring groove of the upper ring body with the top of the protrusion and put it on the protrusion. Finally, fix the upper and lower ring bodies with bolts, so that the main air pipe 223 rotates while the rotating ring does not rotate. The rotating ring and the main air pipe 223 can rise and fall under the pull of the piston rod of the cylinder.

[0046] The rotating shaft 24 is located on the outer wall above the gear ring 25 and is connected to a gas hose. The gas hose is connected to the through hole and is connected to the air pump of the adjusting frame 21. The gas hose, rotating shaft 24, main air pipe 223 and air path support 222 constitute an air path channel. The air pump drives the suction cup 221 to pick up or put down the sodium-ion battery cell through the air path channel.

[0047] The air pump is controlled by the PLC. The air pump draws gas from the negative electrode of the suction cup 221 through the air passage. The cylinder drives the suction cup 221 to descend, and the suction cup 221 picks up the sodium-ion battery. The stability is improved by setting up several suction cups 221.

[0048] The drive cylinder 11 is connected to the rack 23 via a piston rod. The rack 23 is supported by the adjusting frame 21. The drive cylinder 11 is controlled by the drive assembly 4 on the working platform 1.

[0049] The drive assembly 4 includes a hydraulic pump 41 and a pipe 42. The hydraulic pump 41 is connected to the drive cylinder 11 through the pipe 42 and is used to change the position of the piston rod to drive the rack 23 to reciprocate.

[0050] The following uses two cycles as an example to illustrate the working process of the positive and negative electrode adjustment assembly 2:

[0051] When the adjusting frame 21 is performing a reset action and moves to the position of the suction cup 221 above the sodium-ion battery, the hydraulic pump 41 draws liquid from the drive cylinder 11, thereby moving the rack 23 toward the drive cylinder 11 to deviate from the movement trajectory path of the gear ring 25.

[0052] The cylinder drives the suction cup 221 to descend and pick up the sodium-ion battery. The adjusting frame 21 performs a feeding action until the sodium-ion battery moves to the area to be welded. Then the cylinder drives the suction cup 221 to descend and release the sodium-ion battery.

[0053] To start the next cycle, the adjusting frame 21 moves back to reset, picking up the next suction cup 221 again. During this process, the hydraulic pump 41 injects liquid into the drive cylinder 11, thereby pushing the rack 23 to move in the opposite direction to the drive cylinder 11. The rack 23 moves onto the movement path of the gear ring 25, and the adjusting frame 21 performs a feeding action. During the movement, the gear ring 25 passes the rack 23 to drive the rotating shaft 24, the main air pipe 223, and the air path support 222 to rotate synchronously by 180°, which also rotates the sodium-ion battery by 180°. At this time, one sodium-ion battery is stacked on top of the previous sodium-ion battery, and the positive and negative terminals of the stacked sodium-ion batteries are connected so that they can be welded by the welding head 3.

[0054] Example 2:

[0055] See Figures 4-7 The difference between this embodiment and Embodiment 1 lies in the driving component 4; the rest of the structure is the same as in Embodiment 1.

[0056] The drive assembly 4 in this embodiment includes a drive tube 49, a first baffle 43, a second baffle 44, a limiting plate 45, a slotted limiting frame 46, a limiting rod 47, and a top plate 48. The limiting plate 45 is mounted on the working platform 1. The first baffle 43 is fixed on the limiting plate 45. The second baffle 44 slides back and forth along the slide rail on the limiting plate 45. The first baffle 43 and the second baffle 44 are connected by a spring. The piston rod connected to the side of the second baffle 44 extends into the drive tube 49. The drive tube 49 is connected to the drive cylinder 11 through a pipe 42.

[0057] The limiting plate 45 is also provided with a locking groove 451. The bottom end of the limiting rod 47 that slides at the bottom of the second baffle 44 is inserted into the locking groove 451. The slotted limiting frame 46 is connected to the bracket on the limiting plate 45 by a spring. The top plate 48 is fixed on the adjusting frame 21. The top plate 48 is composed of two plates, which are located on both sides of the limiting plate 45. The slotted limiting frame 46 can be set on the same side of either the upper or lower plate. The slotted limiting frame 46 and the first baffle 43 are symmetrically arranged on both sides of the limiting plate 45.

[0058] The slotted limiting frame 46 has an inclined slope at the bottom corner facing the top plate 48. The top plate 48 pushes the slotted limiting frame 46 upward through the inclined slope to offset it from the limiting rod 47. The slot inside the slotted limiting frame 46 is for the limiting rod 47 to be inserted. The slotted limiting frame 46 is used to hold the limiting rod 47 located in the arc-shaped notch.

[0059] The locking groove 451 is composed of an inclined groove 1, a V-shaped groove and an inclined groove 2 that are interconnected. The inclined groove 1 and the inclined groove 2 are respectively arranged on both sides of the V-shaped groove. An arc-shaped notch for accommodating the limiting rod 47 is provided at the included angle of the V-shaped groove. The ends of the inclined groove 1 and the inclined groove 2 are connected.

[0060] The V-groove has an arc-shaped notch positioned towards the connection between the first and second inclined grooves, and the angle between the V-groove and the arc-shaped notch is offset to prevent the limit rod 47 from moving back.

[0061] The movement path of the limiting rod 47 is sequentially inclined groove one, V-groove, inclined groove two, and inclined groove one. Taking the operation of the positive and negative pole adjustment assembly 2 as an example, the upper plate of the top plate 48 and the slotted limiting frame 46 are set on the same side of the limiting plate 45, and the lower plate of the top plate 48 is set on the other side of the limiting plate 45.

[0062] First cycle:

[0063] At this time, the limiting rod 47 is located at the connection between the second inclined groove and the first inclined groove. When the adjusting frame 21 is performing the reset action, the top plate 48 on the adjusting frame 21 first contacts the inclined surface of the slotted limiting frame 46. As the adjusting frame 21 and the top plate 48 continue to move, the lower plate of the top plate 48 slowly lifts the slotted limiting frame 46 towards the support direction and slowly compresses the spring to generate a rebound force. After the lower plate lifts the slotted limiting frame 46, it contacts one side of the slotted limiting frame 46 and the surface of the limiting plate 45. At this time, after the slotted limiting frame 46 is lifted, the limiting rod 47 will not collide with the slotted limiting frame 46 after it moves.

[0064] As the upper plate continues to move and contacts the second baffle 44, pushing the second baffle 44 towards the first baffle 43, the second baffle 44 compresses the spring during its movement. The limiting rod 47 moves from the connection between the first and second inclined grooves towards the connection between the second inclined groove and the V-shaped groove. While sliding along the locking groove 451, the limiting rod 47 can also slide along the second baffle 44. As the second baffle 44 moves, the piston rod connected to the side of the second baffle 44 moves towards the drive tube 49. The drive tube 49 injects liquid into the drive cylinder 11, pushing the rack 23 towards the moving path of the gear ring 25. When the limiting rod 47 moves to the connection between the second inclined groove and the V-shaped groove, the suction cup 221 is above the sodium-ion battery. The cylinder drives the suction cup 221 to descend and pick up the sodium-ion battery. At this time, the rack 23 continues to move.

[0065] When the adjusting frame 21 performs the feeding action, the upper plate moves in the opposite direction. Under the push of the spring, the second baffle 44 moves away from the first baffle 43. At this time, under the action of the spring, the second baffle 44 is pushed back, and the limiting rod 47 moves from the inclined groove to the V-groove direction. As the limiting rod 47 moves to the angle of the V-groove, the spring pushes the limiting rod 47 to be stuck in the arc-shaped notch position. At this time, the rack 23 is located on the moving path of the gear ring 25. As the upper plate continues to move in the opposite direction, the second baffle 44 first separates from the upper plate, and then the lower plate separates from the slotted limiting frame 46. At this time, under the action of the spring rebound force, the slotted limiting frame 46 descends and is stuck by the limiting rod 47.

[0066] During the movement, the gear ring 25 drives the rotating shaft 24, main air pipe 223 and air circuit support 222 to rotate synchronously by 180° via the rack 23, and after rotating the sodium-ion battery by 180°, the rotated sodium-ion battery is placed in the area to be welded.

[0067] Start the next cycle:

[0068] The adjusting frame 21 moves back to perform a reset action. During the movement, the gear ring 25 rotates 180° through the rack 23. The top plate 48 on the adjusting frame 21 first contacts the inclined surface of the slotted limit frame 46. The lower plate of the top plate 48 slowly lifts the slotted limit frame 46 towards the support. After the slotted limit frame 46 is lifted, the limit rod 47 moves and will not collide with the slotted limit frame 46.

[0069] As the upper plate continues to move and contacts the second baffle 44, it pushes the second baffle 44 to move towards the first baffle 43. During the movement, the second baffle 44 compresses the spring, and the limiting rod 47 moves from the connection of the V-groove towards the second inclined groove. The piston rod connected to the side of the second baffle 44 moves towards the drive tube 49. The drive tube 49 injects liquid into the drive cylinder 11, pushing the rack 23 to move towards the moving path of the gear ring 25. When the limiting rod 47 moves to the connection of the second inclined groove and the V-groove, the suction cup 221 is above the sodium-ion battery. The cylinder drives the suction cup 221 to descend and pick up the sodium-ion battery. At this time, the rack 23 continues to move.

[0070] When the adjusting frame 21 performs a feeding action, the upper plate moves in the opposite direction. Under the push of the spring, the second baffle 44 moves away from the first baffle 43. At this time, under the action of the spring, the second baffle 44 is pushed back, and the limiting rod 47 moves in the connection direction of the second inclined groove and the first inclined groove. As the upper plate continues to move in the opposite direction, the second baffle 44 first disengages from the upper plate, and then the lower plate disengages from the slotting limiting frame 46. At this time, under the action of the spring rebound force, the slotting limiting frame 46 descends and is locked by the limiting rod 47 into the second inclined groove and the first inclined groove. At the connection point of the first groove, when the limiting rod 47 moves toward the connection direction of the second groove and the first groove, the piston rod connected to the side of the baffle 2 44 moves away from the drive tube 49. The drive tube 49 draws liquid from the drive cylinder 11, pushing the rack 23 to move away from the moving path of the gear ring 25. At this time, the gear ring 25 moves while keeping the sodium-ion battery stationary. At this time, a sodium-ion battery is stacked on the previous sodium-ion battery, and the positive and negative terminals of the stacked sodium-ion batteries are connected so that they can be welded by the welding head 3.

[0071] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
