It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0046] Please refer to Figure 1-Figure 6 , a capacitor lamination machine, comprising:

[0047] The turntable 100 is driven by a rotating motor. A plurality of workstations 110 arranged in a circular array are formed on the turntable 100. A material bin 120 is provided on each workstation 110. The rotating motor drives the turntable 100 to rotate one workstation 110 at a time.

[0048] The material pressing mechanism 200 is arranged corresponding to the material bin 120 and fixed on the turntable 100. The material pressing mechanism 200 includes a material pressing moving module and a material pressing arm 210;

[0050] The positive electrode cutting sheet feeding mechanism 400 includes a second feeding and pulling module 410, a second laser scanning module 420, a second pin feeding module 430, a second pin cutting module 440, a second cold welding module 450, a second flattening module 460, a positive electrode cutting module 470 and a positive electrode loading module 480. The second feeding and pulling module 410 conveys the negative electrode material strip, the second laser scanning module 420 sweeps out a plurality of welding grooves on the positive electrode material strip, the second cold welding module 450 welds the positive electrode material strip and the positive electrode pin material strip conveyed by the second pin feeding module 430 into one, the second pin cutting module 440 cuts the welded positive electrode pin material strip to form a positive electrode pin, the second flattening module 460 flattens the welding point between the positive electrode pin material strip and the positive electrode material strip, the positive electrode cutting module 470 cuts the welded positive electrode material strip to form a positive electrode foil, and the negative electrode loading module 380 conveys the positive electrode foil to the silo 120;

[0051] A plurality of electrolytic paper cutting sheet feeding mechanisms 500, including a third material pulling and feeding module 510, an electrolytic paper cutting sheet module 520 and an electrolytic paper loading module 530, wherein the third material pulling and feeding module 510 conveys the electrolytic paper material strip to the electrolytic paper cutting sheet module 520, the electrolytic paper cutting sheet module 520 cuts the electrolytic paper material strip into sheets of electrolytic paper, and the electrolytic paper loading module 530 conveys the electrolytic paper to the silo 120;

[0052] The aluminum sheet feeding mechanism 600 includes an aluminum sheet bin 610 and an aluminum sheet feeding robot 620 . The aluminum sheet feeding robot 620 transports the aluminum sheets in the aluminum sheet bin 610 to the bin 120 .

[0053] The positive and negative foils are first formed into welding grooves before the pins are welded, which reduces the thickness of the welding point and avoids the welding point being too protruding and affecting the overall performance. The pin strip is welded to the electrode strip and then cut, which improves work efficiency and eliminates the process of multiple handling and positioning. Similarly, the positive and negative foils are first welded to the pins before cutting, which only requires one handling and positioning, which also improves work efficiency. After the electrolytic paper strip is cut, it is directly transported to the silo 120 for lamination. The overall process is compact and coherent with high efficiency. Lamination is carried out through the turntable 100, which is convenient and simple, and different cut pieces can be laminated at the same time, and multiple capacitors can be laminated one by one, which is efficient. A pressing mechanism 200 is also provided on the turntable 100, and the material is pressed after each lamination to prevent the capacitor lamination from being too fluffy and detaching from the silo 120.

[0054] Please refer to Figure 1 and Figure 2 , one of the positive electrode sheet feeding mechanism 400 and the negative electrode material feeding mechanism is located at one end of the turntable 100, and the other is located at the other end of the turntable 100, and a plurality of electrolytic paper sheet feeding mechanisms 500 are arranged on both sides of the line connecting the positive electrode sheet feeding mechanism 400 and the negative electrode material feeding mechanism. Usually, the number of electrolytic paper sheet feeding mechanisms 500 on both sides is the same. Circular lamination, high efficiency. It can be understood that the number of electrolytic paper sheet feeding mechanisms 500 is generally set according to the number of electrolytic papers between the positive electrode foil and the negative electrode foil. Simply, if there are N layers of electrolytic paper between the adjacent positive electrode foil and the negative electrode foil, 2N electrolytic paper sheet feeding mechanisms 500 are generally set, that is, N electrolytic paper sheet feeding mechanisms 500 are set on each side.

[0055] Please refer to Figure 1 , Figure 2 and Figure 5 The aluminum sheet feeding mechanism 600 and one of the electrolytic paper sheet feeding mechanisms 500 share a station 110. One of the aluminum sheet feeding mechanism 600 and the electrolytic paper sheet feeding mechanism 500 that share a station 110 is directly opposite to the station 110, and the other is tilted. The structure is compact, saving space occupation, and the aluminum sheet is generally only set on the top and bottom layers of the capacitor core, with a small number of stacking times. If the station 110 is occupied alone, there will be multiple empty stacks and discontinuity.

[0056] Please refer to Figure 1 and Figure 2, and also includes a material unloading mechanism 700, which includes a moving mechanism 710 and a material unloading clamp 720, and the material unloading clamp 720 clamps the laminated capacitor core from one of the bins 120. The material unloading mechanism 700 is set to take out the laminated capacitor core to avoid interfering with the operation of the turntable 100 and affecting the continuity, and the lamination can be continued without stopping. The material unloading clamp 720 can be clamped by a cylinder drive. The moving mechanism 710 can be single-axis, double-axis or multi-axis as needed.

[0057] Please refer to Figure 1 and Figure 2 The unloading mechanism 700 shares a workstation 110 with one of the electrolytic paper cutting sheet feeding mechanisms 500. One of the unloading mechanism 700 and the electrolytic paper cutting sheet feeding mechanism 500 sharing a workstation 110 is directly opposite to the workstation 110, and the other is tilted. Similarly, unloading is required only after multiple stacking. If a single workstation 110 is occupied, there will be an empty stacking position, which affects the consistency and efficiency.

[0058] Please refer to Figure 1 , Figure 2 and Figure 6 , and also includes a bundling mechanism 800, which includes a driving motor 810, a rotating mechanism 820, a clamping mechanism 830 and a tape conveying mechanism 840. The clamping mechanism 830 clamps the capacitor core, and the driving motor 810 drives the rotating mechanism 820 to rotate. The rotating mechanism 820 drives the clamping mechanism 830 to rotate so that the tape conveyed by the tape conveying mechanism 840 is wound around the capacitor core. The stacked capacitor core is bundled by the bundling mechanism 800 to avoid scattered loss and facilitate subsequent operations. In particular, the rotating mechanism 820 includes a main transmission mechanism 821, a first branch transmission mechanism 822, and a second branch transmission mechanism 823, and the clamping mechanism 830 includes a first clamping jaw 831 and a second clamping jaw 832. The main transmission mechanism 821 synchronously drives the first branch transmission mechanism 822 and the second branch transmission mechanism 823 to rotate, the first branch transmission mechanism 822 drives the first clamping jaw 831 to rotate, and the second branch transmission mechanism 823 drives the second clamping jaw 832 to rotate, and the first clamping jaw 831 and the second clamping jaw 832 respectively clamp the two ends of the capacitor core. In particular, the tape conveying mechanism 840 releases two tapes set at intervals at the same time.

[0059] Please refer to Figure 1 and Figure 2, the positive electrode loading module 480 and the negative electrode loading module 380 are both composed of a mobile manipulator 381 and a vacuum adsorption head 382. Generally, the mobile manipulator 381 includes horizontal linear movement and lifting movement, that is, two-axis movement, and a three-axis movement or a four-axis movement manipulator 381 can also be used as needed. Preferably, the lifting movement is a motor screw moving mechanism 710. Since the thickness will increase after lamination, the motor screw moving mechanism 710 can be easily adjusted.

[0060] Please refer to Figure 1-Figure 4 The first feeding and pulling module 310, the second feeding and pulling module 410, the third feeding and pulling module, the first pin feeding module 330, and the second pin feeding module 430 all include a discharge roller 311, a tension roller group 312, an auxiliary roller group 313, a pulling cylinder 314, a feeding cylinder 315, a feeding slider 316, and a guide rail 317. The feeding slider 316 clamps the material strip, and the pulling cylinder 314 drives the feeding slider 316 to move along the guide rail 317. Pulling materials through the cylinder is convenient and simple, with high length consistency and convenient reciprocation. The tension of the material strip is ensured by the tension roller group 312 to avoid affecting other operations and ensure the consistency of the pulling length. The auxiliary roller group 313 is generally arranged at both ends of each other mechanism (laser scanning module, cold welding module, flattening module, cutting module) to ensure the stability of other operations and ensure that the material strip transmission is not offset.

[0061] Preferably, the first laser cutting module 320, the first cold welding module 350, the first flattening module 360, the second laser cutting module 420, the second cold welding module 450, and the second flattening module 460 all include a motor screw lifting mechanism 321. The motor screw lifting mechanism has high precision.

[0062] Please refer to Figure 2-Figure 5 The first pin cutting module 340, the second pin cutting module 440, the positive electrode cutting module 470 and the negative electrode cutting module 370 all include a cutting cylinder 341, a knife seat 342 and a blade. The knife seat 342 and the blade are detachably connected. The cutting cylinder 341 drives the knife seat 342 to rise and fall or rotate through the lever principle. That is, the lifting cutting method can be adopted, and a hinge can be set in the middle of the knife seat 342 to swing and cut using the lever principle. The specific selection can be made according to needs.

[0063] It can be understood that the material bin 120 is provided with a relief groove 121 for the material pressing arm 210 of the material pressing mechanism 200 to extend into. Generally, each material pressing mechanism 200 is provided with two material pressing arms 210, and the two material pressing arms 210 respectively press the ends of the cut pieces. The material bin 120 is also provided with a relief notch 122 for the material unloading clamp 720 of the material unloading mechanism 700 to extend into.

[0064] In particular, the pressing and moving module includes a lifting and pressing module and a forward and backward moving module. The lifting and pressing module of the pressing mechanism 200 is fixed on the turntable 100, and the lifting and pressing module is connected to a lifting platform 220. The lifting and pressing module drives the lifting platform 220 to move up and down. The forward and backward moving modules corresponding to the number of the bins 120 are assembled on the lifting platform 220, and the forward and backward moving modules drive the pressing arm 210 to move forward and backward. Simply, the lifting and pressing module can use a motor screw module, and the forward and backward moving module generally uses a cylinder with a guide rail slider mechanism for linear movement.

[0065] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0066] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0067] In summary, the present invention provides a capacitor laminating machine, in which welding grooves are first formed on both the positive and negative foils before the pins are welded, which reduces the thickness of the weld and avoids the weld being too protruding and affecting the overall performance. The pin strip is welded to the electrode strip and then cut, which improves work efficiency and eliminates the process of multiple handling and positioning. Similarly, the positive and negative foils are first welded with pins before cutting, which only requires one handling and positioning, and also improves work efficiency. After the electrolytic paper strip is cut, it is directly transported to the silo for lamination, and the overall process is compact and coherent with high efficiency. Lamination is carried out on a turntable, which is convenient and simple, and different cut pieces can be laminated at the same time, and multiple capacitors can be laminated one by one, which is highly efficient. A pressing mechanism is also provided on the turntable, and the material is pressed after each lamination to prevent the capacitor lamination from being too fluffy and falling out of the silo.
