Description

Technical Field

[0001] This utility model relates to the field of electrode manufacturing equipment technology, specifically to an automatic electrode splicing device. Background Technology

[0002] The processing steps of electrode sheets, such as rolling, slitting, and laser die-cutting, require the removal of defective incoming materials. When removing defective products, the equipment needs to be stopped. Then, the identified defective products are cut off, and the remaining good electrode sheets are connected to the front and rear electrode sheets on the tape-joining platform by manually applying adhesive. The connected electrode sheets continue to the subsequent production.

[0003] Currently, the main process used in lithium battery manufacturing is manual electrode splicing, which is roughly as follows: 1. The operator holds a knife to cut off the defective electrode; 2. Align the good electrode sheets after removing the defective ones, and then use tape to stick the front and back of the electrode sheets together.

[0004] Manual tape application requires high skill from employees. Uneven application or exposed adhesive surfaces during the application process can cause gaps in the electrode sheets at the tape splicing points, leading to tape breakage and impacting equipment utilization and yield.

[0005] Manual application of adhesive has limitations in size range; electrode sheets wider than 1000mm require two people to work together, increasing labor costs. Utility Model Content

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] Reference Figure 1 This utility model provides an automatic electrode splicing device, including an operating platform 1, two sets of electrode adsorption components 4, a tape unwinding component 5, a tape stretching component 6, a tape reversal limiting component 7, and a tape cutting component 8. Along the moving direction of the electrode 9, a front pressure rod 3 and a rear pressure rod 2 are installed on the operating platform 1. The electrode adsorption components 4 are used to adsorb two electrode 9 to be bonded and move them to a designated position to avoid the subsequent adhesive application action. The two sets of electrode adsorption components 4 are arranged between the front pressure rod 3 and the rear pressure rod 2. The tape unwinding component 5 is used to unwind the tape 10. The tape stretching component 6 is used to clamp the tape 10 and drive the tape 10 to move. The tape reversal limiting component 7 is used to limit the reverse position of the tape 10 when the tape stretching component 6 drives the tape to reverse. The tape cutting component 8 is used to cut the tape 10.

[0039] As a preferred embodiment, refer to Figure 2 The electrode adsorption assembly 4 includes a second bracket 411 fixed on the operating platform 1, a mounting plate 412 rotatably connected to the second bracket 411, a plurality of suction nozzles 413 disposed on the mounting plate 412, a first cylinder connected to the suction nozzles 413, and a first motor driving the mounting plate 412 to rotate. The suction nozzles 413 face the electrode 9 and the suction nozzles 413 can adsorb the electrode 9 at least 90°.

[0040] Furthermore, the second support 411 includes a top plate, two side plates detachably fixed to the operating platform 1 and supporting both sides of the top plate, and a first connecting plate 415 disposed between the two side plates and located below the top plate. The first connecting plate 415 is rotatably connected to the mounting plate 412, and a first motor is fixed to the first connecting plate 415. The electrode adsorption assembly 4 also includes a first lifting drive 414 fixed to the top plate. The first lifting drive 414 has a lifting shaft that moves through the top plate and connects to the first connecting plate 415 to drive the mounting plate 412 to perform lifting movements, thereby causing the suction nozzle 413 to move closer to or away from the electrode 9.

[0041] When it is necessary to attach the electrode sheet, the first lifting drive 414 drives the suction nozzle 413 to approach the electrode sheet 9. When the suction nozzle 413 is close to the electrode sheet 9, the first cylinder is activated to make the suction nozzle 413 adsorb the electrode sheet 9. The first lifting drive 414 drives the mounting plate 412 to rise, and then the first motor drives the mounting plate 412 to rotate, so that the mounting plate 412 rotates at least 90° to provide laying space for the tape 10. This allows the tape stretching assembly 6 to pull the tape 10 to lay on the operating platform, so that the tape 10 can be pasted on both the front and back of the electrode sheet 9.

[0042] Furthermore, the electrode adsorption assembly 4 also includes at least two first slide rails 416 respectively fixed in the two side plates and two first sliders 417 respectively slidably connected to the first slide rails 416. The first sliders 417 are detachably connected to the first connecting plate 415. The first slide rails 416 and the first sliders 417 are used to limit the lifting and lowering movement of the first connecting plate 415.

[0043] As another preferred embodiment, refer to Figure 3 The electrode adsorption assembly 4 includes a third bracket 421 fixed on the operating platform 1, an adsorption plate 422 rotatably connected to the third bracket 421, and a second motor that drives the adsorption plate 422 to rotate. The adsorption plate 422 can rotate at least 90° after adsorbing the electrode 9.

[0044] It should be noted that an air cavity is provided in the adsorption plate 422, and multiple suction holes are provided on the lower surface of the adsorption plate 422 (the surface facing the electrode 9). The suction holes are connected to the air cavity, and a negative pressure can be generated in the air cavity to allow the adsorption plate 422 to adsorb the electrode 9.

[0045] Furthermore, the third support 421 includes a top plate, two side plates detachably fixed to the operating platform 1 and supporting both sides of the top plate, and a second connecting plate 424 disposed between the two side plates and located below the top plate. The second connecting plate 424 is rotatably connected to the adsorption plate 422, and a second motor is fixed to the second connecting plate 424. The electrode adsorption assembly 4 also includes a second lifting drive 423 fixed to the top plate. The second lifting drive 423 has a lifting shaft that moves through the top plate and connects to the second connecting plate 424 to drive the adsorption plate 422 to move up and down, thereby moving the adsorption plate 422 closer to or away from the electrode 9.

[0046] When it is necessary to attach the electrode sheet, the second lifting drive 423 drives the adsorption plate 422 to approach the electrode sheet 9. After the adsorption plate 422 is close to the electrode sheet 9 and adsorbs the electrode sheet 9, the second lifting drive 423 drives the adsorption plate 422 to rise. Then the second motor drives the adsorption plate 422 to rotate, so that the adsorption plate 422 rotates at least 90°, so that the tape 10 can provide laying space. This allows the tape stretching assembly 6 to pull the tape 10 to lay it on the operating platform, so that the tape 10 can be pasted on both the front and back of the electrode sheet 9.

[0047] Furthermore, a buffer pad can be provided on the surface of the adsorption plate 422 adsorbing the electrode 9. The buffer pad can be made of materials such as rubber or silicone. The buffer pad can prevent the adsorption plate 422 from colliding with the electrode 9 and causing damage to the electrode 10.

[0048] Furthermore, the electrode adsorption assembly 4 also includes at least two second slide rails 425 respectively fixed in the two side plates and two second sliders 426 respectively slidably connected to the second slide rails 425. The second sliders 426 are detachably connected to the second connecting plate 424. The second slide rails 425 and the second sliders 426 are used to limit the lifting and lowering movement of the second connecting plate 424.

[0049] Reference Figure 4 The tape stretching assembly 6 includes a first bracket 61 and a first clamp 65 fixed on the operating platform 1. The first clamp 65 is used to clamp the tape 10. The first clamp 65 can reciprocate in a direction perpendicular to the moving direction of the electrode 9, so that the tape 10 is pasted on the back and front of the electrode.

[0050] Furthermore, the tape stretching assembly 6 also includes a third lifting drive 64 connected to the first clamp 65 and driving the first clamp 65 to move up and down, and a third drive 62 driving the third lifting drive 64 to reciprocate along a direction perpendicular to the movement of the electrode 9. The third drive 62 is fixed on the first bracket 61, and the third lifting drive 64 is fixed on the third connecting plate 63. The third connecting plate 63 is connected to the third drive 62 and is driven by the third drive 62 to reciprocate along a direction perpendicular to the movement of the electrode 9.

[0051] Furthermore, the first support 61 includes a support plate extending along the width direction of the electrode 9 and two columns located on both sides of the electrode 9 and connected to both ends of the support plate. The columns are detachably fixed to the operating platform 1, and the third drive component 62 is fixed to the support plate. The tape stretching assembly 6 also includes a third slide rail 67 fixed to the support plate and a third slider slidably connected to the third slide rail 67. The third slider is detachably connected to the third connecting plate 63.

[0052] Reference Figure 5 The first chuck 65 includes two grippers 652 and a second cylinder 651 for driving the two grippers 652 to clamp or open. The tape stretching assembly 6 includes a fourth connecting plate 66, which is connected to the third lifting drive 64, and the second cylinder 651 is detachably fixed to the fourth connecting plate 66.

[0053] The two grippers 652 are an upper gripper and a lower gripper. The upper gripper has an upper clamping plate 6522, and the lower gripper has a lower clamping plate 6521. When the second cylinder 651 drives the upper and lower grippers to clamp, the lower surface of the lower clamping plate 6521 is lower than the lower surface of the second cylinder 651. At the same time, the upper surfaces of the lower clamping plate 6521 and the upper clamping plate 6522 are both inclined surfaces, so that the thickness of the free end of the lower clamping plate 6521 gradually decreases, thereby facilitating the insertion of the lower clamping plate 6521 under the tape 10 and clamping the tape 10 between the lower clamping plate 6521 and the upper clamping plate 6522.

[0054] Furthermore, in order for the tape 10 to detach from the lower clamping plate 6521 and the upper clamping plate 6522 during the reciprocating movement of the first clamping head 65 along the width direction of the electrode plate 9 by the third driving member 62, at least one set of mutually cooperating grooves 6523 and protrusions 6524 are provided between the lower clamping plate 6521 and the upper clamping plate 6522.

[0055] The tape reverse limiting assembly 7 and the tape unwinding assembly 5 are respectively located on opposite sides of the electrode adsorption assembly 4. The tape reverse limiting assembly 7 includes a heat-conducting wire 70, a winding unit 71, and a heat-conducting wire stretching unit 72. One end of the heat-conducting wire 70 is connected to the winding unit 71 and wound on the spool of the winding unit 71. The heat-conducting wire stretching unit 72 is arranged opposite to the winding unit 71 along the moving direction of the electrode. The heat-conducting wire stretching unit 72 is used to clamp the other end of the heat-conducting wire 70 and drive the heat-conducting wire 70 to reciprocate along the moving direction parallel to the moving direction of the electrode 9.

[0056] Preferably, the heat-conducting wire stretching unit 72 includes a linear reciprocating motor fixed on the operating platform 1 and a second chuck connected to the linear reciprocating motor, with the linear reciprocating motor located on the inner side of the column. The second chuck may be a pneumatic gripper.

[0057] When the third drive unit 62 drives the first chuck 65 to pull the tape 10 along the width of the electrode 9, and both ends of the tape 10 laid on the operating platform 1 extend 2-3 mm beyond the edge of the electrode 9, the linear reciprocating motor drives the second chuck to approach the winding unit 71. Then, the second chuck clamps the heat-conducting wire 70. Finally, the linear reciprocating motor drives the second chuck to reset, so that the heat-conducting wire 70 is above the tape 10. After the heat-conducting wire 70 passes through the tape 10, the third lifting drive unit 64 drives the first chuck 65 to rise above the heat-conducting wire 70. Then, the third drive unit 62 drives the first chuck 65 to move the tape 10 from above the heat-conducting wire 70 towards the tape unwinding assembly 5.

[0058] Furthermore, the automatic electrode splicing device also includes a pressure roller, which is used to press the tape 10 and the electrode 9 together to ensure complete adhesion between the tape and the electrode. The pressure roller is fixed on the fourth connecting plate 66 and located below the second cylinder 651. As the third driving member 62 drives the first chuck 65 to move the tape 10 from above the heat-conducting wire 70 towards the tape unwinding assembly 5, the pressure roller can simultaneously press the tape 10.

[0059] The tape cutting assembly 8 includes a cutter and a horizontal drive that drives the cutter to move in a direction parallel to the movement of the electrode 9.

[0060] Furthermore, the operating platform 1 is provided with a through slot, in which the cutting blade is movably configured. The tape cutting assembly 8 also includes a second drive member that drives the cutting blade to extend out of or retract into the through slot.

[0061] When electrode 9 needs to be spliced, the operation process of this utility model is roughly as follows:

[0062] 1. Close the front pressure rod 3 and the rear pressure rod 2 to prevent the electrode 9 from moving.

[0063] 2. The two sets of electrode adsorption components 4 adsorb two electrodes 9 to be bonded respectively, and drive the electrodes 9 to move upward a specified distance and then flip them 90°.

[0064] 3. The third driving component 62 drives the tape unwinding assembly 5. After the first chuck 65 clamps the tape 10, the third driving component 62 drives the first chuck 65 to pull the tape 10 along the width direction of the electrode 10 towards the tape reverse limiting assembly 7. When both ends of the tape 10 laid on the operating platform 1 exceed the edge of the electrode 9 by 2-3mm, the heat-conducting wire stretching unit 72 pulls the heat-conducting wire 70 through the tape 10 above it.

[0065] 4. The third driving component 62 drives the first chuck 65 to move the tape 10 from the top of the heat-conducting wire 70 towards the tape unwinding assembly 5, while the pressure roller presses the tape 10.

[0066] 5. On the side near the tape unwinding assembly 5, after the tape on both the front and back of the electrode 9 extends 2-3mm beyond the edge of the electrode 9, the cutter of the tape cutting assembly 8 cuts the tape 10.

[0067] This invention achieves automatic electrode splicing through the cooperation of an electrode adsorption component, a tape unwinding component, a tape stretching component, a tape reverse limiting component, and a tape cutting component. The splicing efficiency is high and the adhesive is smooth. No machine downtime is required, which improves equipment utilization, frees up manpower, and reduces labor costs.

[0068] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to the above embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
