[0034] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0035] Please refer to Figures 1 to 17 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, which is a fully automatic digital battery wire bonding device.

[0036] Among them, the first wire bonding mechanism 50, the second wire bonding mechanism 30, the first coating mechanism 60, the tab bending mechanism 70, and the second coating mechanism 80 can correspondingly complete the welding of the first wire 516, the welding of the second wire, the coating of the tab, the bending of the tab, and the coating of the battery 16. Therefore, the fully automatic digital battery wire bonding equipment has more complete functions and higher automation.

[0037] This application provides a fully automatic digital battery wire bonding device, including a first transfer mechanism 41; a turntable mechanism 40 disposed beside the first transfer mechanism 41; a first wire bonding mechanism 50, a second wire bonding mechanism 30, a first coating mechanism 60, a tab folding mechanism 70, a second coating mechanism 80, and a second transfer mechanism 90 disposed outside the turntable mechanism 40; the first transfer mechanism 41 can load the battery 16 onto the first carrier 412 of the turntable mechanism 40; the first wire bonding mechanism 50 bonds the first wire 516 to the battery. The battery 16 has a first tab 17; a second wire bonding mechanism 30 bonds a second wire to the second tab 18 of the battery 16; a first adhesive wrapping mechanism 60 wraps a first adhesive tape 617 around the battery 16; a tab bending mechanism 70 bends the first tab 17 and the second tab 18 of the battery 16; a second transfer mechanism 90 transfers the battery 16 from the first carrier 412 to the second adhesive wrapping mechanism 80; after the second adhesive wrapping mechanism 80 wraps a second adhesive tape 811 around the battery 16, the second transfer mechanism 90 can recycle the battery 16. The first transfer mechanism 41 includes a first robotic arm 430, which can be a gantry robotic arm. The first robotic arm 430 has one or more first transfer suction cups 431. In this embodiment, there are three first transfer suction cups 431. The first transfer suction cups 431 of the first robotic arm 430 can move up and down by being driven by a cylinder. The first robotic arm 430 picks up the battery 16 and places it into the first carrier 412 of the turntable mechanism 40. The first carrier 412 then passes through the first wire bonding mechanism 50, the second wire bonding mechanism 30, the first coating mechanism 60, and the tab bending mechanism 70. The first wire bonding mechanism 50 bonds the first wire 516 to the first tab 17. The second wire bonding mechanism 30 bonds the first wire to the second tab 18. The first coating mechanism 60 coats the tab with adhesive. The tab bending mechanism 70 bends the tab. After the tab is bent, the second transfer mechanism 90, including the second robotic arm, uses a second suction cup on the second robotic arm to transfer the battery 16 from the first carrier 412 to the second coating mechanism 80 for a second coating. After the battery 16 is coated a second time, the second transfer mechanism 90 retrieves the battery 16. Therefore, this fully automatic digital battery wire bonding equipment has more functions and a higher degree of automation. Even better, a wire-picking mechanism 420 is provided on the outside of the turntable 418. This mechanism 420 includes a lever 423, which can be inserted into the gap between the first wire 516 and the second wire, and move either the first wire 516 or the second wire. A second cylinder 422 is located at the output end of the first cylinder 421, and the lever 423 is located at the output end of the second cylinder 422. With the cooperation of the first cylinder 421 and the second cylinder 422, the lever 423 can separate the first wire 516 and the second wire by a certain distance, thus ensuring the safety of the subsequent second coating process.

[0038] More specifically, the fully automated digital battery wire bonding equipment in this embodiment also includes a tab straightening and detection mechanism 20, a tab cutting mechanism 24, and a material preparation mechanism 10. The tab straightening and detection mechanism 20, the tab cutting mechanism 24, and the material preparation mechanism 10 are located beside the first transfer mechanism 41. The first transfer mechanism 41 can load the battery 16 from the material preparation mechanism 10 onto the tab straightening and detection mechanism 20 and the tab cutting mechanism 24. The tab straightening and detection mechanism 20 can detect the battery 16 and straighten the tabs. The tab cutting mechanism 24 can cut the tabs. A first detection camera 29 is arranged beside the first wire bonding mechanism 50. A second detection camera 324 is arranged beside the second wire bonding mechanism 30. The first detection camera 29 can detect the tabs. The second detection camera 324 can detect the welding quality. The first detection camera 29 and the second detection camera 324 are CCD cameras. The tab straightening and testing mechanism 20 can straighten the tabs of the battery 16 and also test the internal resistance, charge, and voltage of the battery 16. The third cutter 26 of the tab cutting mechanism 24 can cut the tabs to the designed size. The material preparation mechanism 10 can provide the battery 16, and the first transfer mechanism 41 picks up the battery 16 from the material preparation mechanism 10 and then loads the battery 16 onto the first carrier 412. The first inspection camera 29 inspects the quality of the cut tabs, and the second inspection camera 324 inspects the quality of the bonding wires.

[0039] The material preparation mechanism 10 includes a material preparation conveyor belt 11 and a rotatable material preparation rack 14 mounted on the conveyor belt 11. The rack 14 is equipped with suction heads 15 that can hold batteries 16 and then lower them onto the conveyor belt 11. A fifth rotary cylinder 13 is connected to the rack 14 and drives it to rotate. A sixth linear module 12, driven by a cylinder, drives the rack 14 to move up and down. Multiple suction heads 15 are present. This design allows for large-scale material preparation with high efficiency. Furthermore, the rack 14 is rotatable, which facilitates holding the batteries 16 and provides greater flexibility in the receiving angle.

[0040] The electrode straightening and testing mechanism 20 includes a third carrier 22 and a straightening clamp 23 disposed on one side of the third carrier 22. The third carrier 22 is driven by a third cylinder 21 and can clamp the battery 16 to prevent it from loosening. The third cylinder 21 drives the straightening clamp 23 to move toward the electrode of the battery 16 on the third carrier 22, clamping the electrode and straightening it. More preferably, the clamp of the straightening clamp 23 is provided with a detection spring. When the straightening clamp 23 clamps the electrode, the detection spring contacts the electrode, thereby enabling the battery 16 to be tested. This method of straightening and testing is performed simultaneously, resulting in higher work efficiency.

[0041] The electrode cutting mechanism 24 includes a third cutter 26, a cutter holder 27 located below the third cutter 26, and a waste trough 28 located beside the cutter holder 27. The electrode of the battery 16 extends into the cutter holder 27, and a fourth cylinder 25 drives the third cutter 26 to move towards the electrode, cutting it to the designed length. The waste material from the cutting falls into the waste trough 28. This structure is simple and highly efficient.

[0042] Preferably, the first wire bonding mechanism 50 includes a first upper wire device 510, a first upper welding needle device 520, and a first lower welding needle device 522. The first upper wire device 510 can rotate the first wire 516 and place it on the first electrode tab 17. The support rod 417 on the first carrier 412 supports the first wire bonding. The first upper welding needle device 520 has a first upper welding needle 521. The first lower welding needle device 522 has a first lower welding needle 523. The first upper welding needle 521 and the first lower welding needle 523 can move toward the first electrode tab 17 and weld the first wire 516 onto the first electrode tab 17. The first wire bonding mechanism 50 is used to weld the first wire 516 onto the first electrode tab 17. When the first carrier 412 moves to the first wire bonding mechanism 50, the first upper wire device 510 first clamps the first wire 516 and rotates it to adjust its direction, and then places the first wire 516 on the first electrode tab 17. The support rod 417 supports the first wire bonding to prevent the first wire 516 from drooping and to ensure the welding quality. The first upper welding pin 521 and the first lower welding pin 523, driven by a ball screw servo module or a cylinder, move toward the electrode and the first wire 516, so that the first wire 516 and the first electrode 17 are welded together.

[0043] The second wire bonding mechanism 30 includes a second upper wire bonding device 310, a second upper welding needle device 320, and a second lower welding needle device 322. The second upper wire bonding device 310 can rotate the second wire and place it on the second electrode tab 18. The support rod 417 on the first carrier 412 supports the second wire bonding. The second upper welding needle device 320 has a second upper welding needle 321. The second lower welding needle device 322 has a second lower welding needle 323. The second upper welding needle 321 and the second lower welding needle 323 can move toward the second electrode tab 18 and bond the second wire to the second electrode tab 18. The second wire bonding mechanism 30 is used to bond the second wire to the second electrode tab 18. When the second carrier 824 moves to the second wire bonding mechanism 30, the second upper wire device 310 first clamps the second wire and rotates it to adjust its direction, then places the second wire on the second electrode tab 18; the support rod 417 supports the second wire to prevent it from sagging and ensures the welding quality; the second upper welding pin 321 and the second lower welding pin 323, driven by a lead screw servo module or cylinder, move toward the electrode tab and the second wire, so that the second wire and the second electrode tab 18 are welded together. Therefore, the first wire bonding mechanism 50 and the second wire bonding mechanism 30 work together to easily weld the first wire 516 and the second wire onto the electrode tab, and the multi-stage welding further ensures the welding quality.

[0044] Preferably, the first loading device 510 includes a first linear module 511, a second linear module 512 disposed on the first linear module 511, a first rotary cylinder 513 disposed on the second linear module 512, a second rotary cylinder 514 disposed on the output end of the first rotary cylinder 513, and a first loading clamp 515 disposed on the output end of the second rotary cylinder 514. The first linear module 511 and the second linear module 512 are lead screw servo modules. The first loading clamp 515 clamps the first wire 516. The first linear module 511, the second linear module 512, the first rotary cylinder 513, and the second rotary cylinder 514 cooperate to allow the first loading clamp 515 to not only flexibly adjust the loading direction of the first wire 516, but also flexibly receive the first wire 516 coming from other directions, making it adaptable to a wide range of scenarios.

[0045] The second wire feeding device 310 includes a third linear module 311, a fourth linear module 312 disposed on the third linear module 311, a third rotary cylinder 313 disposed on the second linear module 312, a fourth rotary cylinder 314 disposed on the output end of the third rotary cylinder 313, and a second wire feeding clamp 315 disposed on the output end of the fourth rotary cylinder 314. The third linear module 311 and the fourth linear module 312 are lead screw servo modules. The second wire feeding clamp 315 can clamp the second wire; with the cooperation of the third linear module 311, the fourth linear module 312, the third rotary cylinder 313, and the fourth rotary cylinder 314, the second wire feeding clamp 315 can not only flexibly adjust the wire feeding direction of the second wire, but also flexibly receive second wires coming from other directions, adapting to a wide range of scenarios.

[0046] The included angle between the first linear module 511 and the third linear module 311 is an acute angle or a right angle. This design makes the layout of the first wire bonding mechanism 50 and the second wire bonding mechanism 30 more flexible, saves more deployment space, and can adapt to the vertical direction of the first wire 516 and the second wire, making it highly versatile.

[0047] Preferably, the first adhesive coating mechanism 60 includes a first material tray 616, a first adhesive pulling device 610, and a first adhesive pressing device 620. The first material tray 616 contains first adhesive paper 617. The first adhesive pulling device 610 can pull the first adhesive paper 617 to the top and bottom surfaces of the electrode tab. The first adhesive pressing device 620 is located at the discharge end of the first adhesive pulling device 610, and the first adhesive pressing device 620 can press the first adhesive paper 617 on the electrode tab. The first material tray 616 contains a large number of first adhesive papers 617, wherein the first adhesive paper 617 is insulating adhesive paper. The first adhesive paper 617 comes out from the first material tray 616, and is then pulled forward by the first adhesive pulling device 610. The first adhesive paper 617 adheres to the top surface of the electrode tab, and then the first adhesive paper 617 is lifted upward and adhered to the top surface of the electrode tab. When the first adhesive paper 617 reaches the desired length, the adhesive paper is cut by the first cutter 615. Next, the first adhesive applicator 620 presses the first adhesive paper 617 onto the electrode tab, so that the first adhesive paper 617 is firmly adhered to the electrode tab. This adhesive applicator mechanism is simple and highly efficient.

[0048] Preferably, the first adhesive-pulling device 610 includes a first adhesive-pulling clamp 611, a first adhesive-pulling seat 612, a fifth linear module 613, and a first lifting module 614; the first adhesive-pulling clamp 611 is disposed on the first adhesive-pulling seat 612, and the first adhesive-pulling clamp 611 can press the first adhesive paper 617 onto the first adhesive-pulling seat 612; the first adhesive-pulling seat 612 is connected to the fifth linear module 613; the fifth linear module 613 is disposed on the first lifting module 614; a first cutter 615 is disposed inside the first adhesive-pulling seat 612, and the first cutter 615 is connected to a first cutter 615 cylinder, which drives the first cutter 615 to extend from the first adhesive-pulling seat 612. The first pressing device 620 includes a first upper pressing seat 621 and a first lower pressing seat 622, which close and press against the first adhesive paper 617 on the electrode tab. The working principle of the first adhesive-pulling device 610 and the first adhesive-pressing device 620 is as follows: the first adhesive-pulling clamp 611 presses down on the adhesive paper; the fifth linear module 613 drives the first adhesive-pulling seat 612 forward, the first adhesive-pulling clamp 611 can be pulled forward, the first adhesive paper 617 moves to the first lower adhesive-pressing seat 622, and the adhesive paper is pre-adheded to the bottom of the electrode tab.

[0049] The fifth linear module 613 drives the first adhesive-pulling seat 612 to retract, and the first adhesive-pulling clamp 611 releases the adhesive paper, which continues to be pulled out. The first lifting module 614 drives the first adhesive-pulling seat 612 to move upward. Then, the fifth linear module 613 drives the adhesive-pulling seat, and the adhesive paper adheres to the top surface of the electrode tab. Next, the first cutter 615 is driven by a cylinder to cut the first adhesive paper 617. 3. The first upper pressure adhesive seat 621 and the first lower pressure adhesive seat 622 are driven by their corresponding cylinders to press the first adhesive paper 617 onto the electrode tab. The first lower pressure adhesive seat 622 presses the bottom surface of the electrode tab, and the first upper pressure adhesive seat 621 presses the top surface of the electrode tab, so that the adhesive paper is firmly adhered to the electrode tab. Therefore, the first adhesive-pulling device 610 and the first pressure adhesive device 620 work together to efficiently stick the adhesive paper onto the electrode tab. The structure is simple and ingenious, the connection is tight, and it helps to improve the adhesive application efficiency.

[0051] During bending, the forming needle 722 moves to the bending position of the tab, and then the tab bending cylinder 715 drives the tab bending clamp 711 to clamp the tab and the forming needle 722 at the same time. Then the forming needle 722 is pulled out and the clamp is released.

When folding the tab, the forming needle 722 cylinder drives the forming needle 722 to move to the tab-folding position. Then, under the combined action of the second lifting module 714 and the eighth linear module 713, the tab-folding clamp 711 moves to the tab position; then, the tab-folding cylinder 715 drives the tab-folding clamp 711 to move, and the tab is bent into the designed shape. After the tab is bent, the tab bending fixture 711 opens, the second lifting module 714 and the eighth linear module 713 reset, and the tab is released. Due to the presence of the forming needle 722, the bending position of the tab will form a shape consistent with the forming needle 722.
