Description

Technical Field

[0001] The utility model relates to the technical field of battery manufacturing equipment, and particularly relates to a short-stroke cutting and stacking integrated machine. Background Art

[0002] The cutting and stacking integrated machine is widely used in the new energy lithium battery manufacturing industry and is the main equipment for manufacturing battery cores at the present stage.

[0003] As Figure 1 and Figure 2 shown, most of the existing stacking tables of the cutting and stacking integrated machine include the following components: a negative electrode conveyor belt 1, a negative electrode conveyor belt sheet-taking manipulator 2 (including a rotating mechanism), a negative electrode deviation correction table sheet-taking manipulator 3, a diaphragm swing roller 4, a positive electrode deviation correction table sheet-taking manipulator 5, a positive electrode conveyor belt sheet-taking manipulator 6 (including a rotating mechanism), a positive electrode conveyor belt 7, a negative electrode pre-positioning platform 8, a positive electrode pre-positioning platform 9, a waste box 10, and a stacking table 11. The positive and negative electrode sheets are grabbed from their respective conveyor lines by the sheet suction devices on the upper linear motor manipulators (the negative electrode conveyor belt sheet-taking manipulator 2 and the positive electrode conveyor belt sheet-taking manipulator 6) and rotated 90° (because the orientation of the sheet during transportation is inconsistent with the stacking orientation), and then transported to the positive and negative electrode deviation correction devices (the positive electrode pre-positioning platform 9 and the negative electrode pre-positioning platform 8). After deviation correction, they are transported to the central stacking table 11 for stacking. Because the distances between each station below are different, each suction device requires a separate power source to displace different strokes. For the four sets of suction devices plus the intermediate diaphragm swing roller mechanism, a total of five movers are required for the linear motor.

[0004] In the existing cutting and stacking integrated machine technology, there is a relatively long distance before the positive and negative electrode conveyor belts in the front section of the equipment for die-cutting and sheet-making. And this distance value usually cannot be further narrowed, resulting in a relatively long distance between the four sections among the five sheet storage stations of each stacking table. This will lead to too long time required for transporting the sheets, affecting the overall efficiency of the machine. Moreover, the rotating mechanisms of the upper negative electrode conveyor belt sheet-taking manipulator 2 and the positive electrode conveyor belt sheet-taking manipulator 6, which are composed of a servo motor and a speed reducer, etc., are relatively heavy, which will affect the acceleration of the linear motor manipulator during translation and lengthen the transportation time. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a short-stroke cutting and stacking integrated machine, aiming to reduce the equipment cost, improve the energy efficiency, and improve the sheet stacking efficiency of the equipment.

[0006] To achieve the above purpose, the utility model provides a short-stroke cutting and stacking integrated machine, including: a frame, a positive electrode sheet conveyor belt, a positive electrode sheet rotating platform, a positive electrode sheet deviation correction table, a lifting stacking table, a negative electrode sheet deviation correction table, a negative electrode sheet rotating platform, and a negative electrode sheet conveyor belt, which are arranged on the frame at equal intervals in sequence;

[0007] Above the positive electrode sheet conveyor belt, the positive electrode sheet rotating platform, the positive electrode sheet deviation rectifying table, the lifting electrode sheet laminating table, the negative electrode sheet deviation rectifying table, the negative electrode sheet rotating platform and the negative electrode sheet conveyor belt, there are three movers arranged equidistantly in sequence and capable of synchronous reciprocating motion. A diaphragm reciprocating swing roller is arranged at the middle position of the middle mover among the three movers. Two manipulators are arranged on each mover, and the distance between every two adjacent manipulators on the three movers is the same.

[0008] A further technical solution of the present utility model is that it further includes a driving mechanism for driving the movement of the movers.

[0009] A further technical solution of the present utility model is that the driving mechanism includes a linear motor arranged on the frame, and the linear motor is connected to the three movers.

[0010] A further technical solution of the present utility model is that the driving mechanism includes a lead screw linear module or a synchronous belt arranged on the frame, and the lead screw linear module or the synchronous belt is connected to the three movers.

[0011] A further technical solution of the present utility model is that the rotation angles of the positive electrode sheet rotating platform and the negative electrode sheet rotating platform are 90°.

[0012] A further technical solution of the present utility model is that the frame includes a base and a mounting plate horizontally arranged on the base. The three movers are arranged equidistantly on the mounting plate, and the lifting laminating table is arranged on the base.

[0013] By canceling the rotating mechanism on the traditional manipulator, at the same time, adding the positive electrode sheet rotating platform between the positive electrode sheet conveyor belt and the positive electrode sheet deviation rectifying table, adding the negative electrode sheet rotating platform between the negative electrode sheet conveyor belt and the negative electrode sheet deviation rectifying table, and the equidistant design among the seven stations, with every two manipulators sharing one mover, the following technical effects can be achieved:

[0014] 1. The number of movers is reduced from five to three, which can reduce costs and improve energy efficiency;

[0015] 2. The number of displacements between the positive electrode conveyor belt and the negative electrode conveyor belt is increased from four sections to six sections, that is, the distance between each station becomes smaller, and the stroke of each displacement of the positive electrode sheet and the negative electrode sheet becomes smaller, thereby shortening the required time and improving the laminating efficiency of the equipment.

[0024] The realization, functional features and advantages of the object of the present invention will be further described with reference to the embodiments and the drawings. Specific embodiments

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0026] Please refer to Figures 3 to 5 , the present invention provides a short-stroke slitting and stacking machine. The preferred embodiment of the short-stroke slitting and stacking machine of the present invention includes a frame, and a positive electrode sheet conveyor belt 1, a positive electrode sheet rotating platform 2, a positive electrode sheet deviation rectifying table 3, a lifting and stacking table 4, a negative electrode sheet deviation rectifying table 5, a negative electrode sheet rotating platform 6 and a negative electrode sheet conveyor belt 7 arranged on the frame at equal intervals in sequence.

[0027] Above the positive electrode tab conveyor belt 1, the positive electrode tab rotating platform 2, the positive electrode tab deviation rectifying platform 3, the lifting tab stacking platform, the negative electrode tab deviation rectifying platform 5, the negative electrode tab rotating platform 6, and the negative electrode tab conveyor belt 7, there are three movers 8 arranged at equal intervals in sequence and capable of synchronous reciprocating motion. A diaphragm reciprocating swing roller 9 is arranged at the middle position of the middle mover 8 among the three movers 8. Two manipulators 10 are arranged on each mover 8, and the distance between every two adjacent manipulators 10 on the three movers 8 is the same.

[0028] The rotation angles of the positive electrode tab rotating platform 2 and the negative electrode tab rotating platform 6 are 90°.

[0029] In this embodiment, without changing the distance between the positive electrode tab conveyor belt 1 and the negative electrode tab conveyor belt 7, by adding the positive electrode tab rotating platform 2 between the positive electrode tab conveyor belt 1 and the positive electrode tab deviation rectifying platform 3, adding the negative electrode tab rotating platform 6 between the negative electrode tab conveyor belt 7 and the negative electrode tab deviation rectifying platform 5, and canceling the rotation mechanism of the manipulator in the prior art, the positive electrode tab on the positive electrode tab conveyor belt 1 is transferred to the positive electrode tab rotating platform 2 by the manipulator 10. After the positive electrode tab rotating platform 2 rotates 90°, the positive electrode tab is transferred to the positive electrode tab deviation rectifying platform 3 by the manipulator 10. The negative electrode tab on the negative electrode tab conveyor belt 7 is transferred to the negative electrode tab rotating platform 6 by the manipulator 10. After the negative electrode tab rotating platform 6 rotates 90°, the negative electrode tab is transferred to the negative electrode tab deviation rectifying platform 5 by the manipulator 10. Thus, the movement distance of the manipulator 10 can be reduced.

[0030] In addition, in this embodiment, the distances between all workstations are equal (a total of seven tab positions, that is, six intervals). Two of the above-mentioned manipulators 10 (taking piece suction cup devices) are installed at equal intervals on each mover 8. Two more of the above-mentioned manipulators 10 are also added on both sides of the middle diaphragm reciprocating swing roller 9, and every two of the manipulators 10 share one mover 8 to meet the requirements, thereby reducing the equipment cost. The six manipulators 10 reciprocate between the seven tab storage workstations to transport the positive and negative electrode tabs to the lifting stacking platform 4 for stacking.

[0031] Furthermore, in this embodiment, the short-stroke cutting and stacking integrated machine further includes a driving mechanism for driving the movement of the mover 8.

[0032] Wherein, the driving mechanism includes a linear motor arranged on the frame, and the linear motor is connected to the three movers 8.

[0033] Alternatively, the driving mechanism includes a lead screw linear module or a synchronous belt disposed on the frame, and the lead screw linear module or the synchronous belt is connected to the three movers 8.

[0034] In this embodiment, the frame includes a base 11 and a mounting plate 12 horizontally disposed on the base 11. The three movers 8 are equidistantly arranged on the mounting plate 12, and the lifting lamination table 4 is disposed on the base 11.

[0035] Hereinafter, taking the linear motor as an example, the working process of the short-stroke cutting and lamination integrated machine of the present invention will be described.

[0036] It should be noted that this embodiment also includes a controller connected to the linear motor. When the controller controls the linear motor to drive the movers 8 to move synchronously in the first direction, the diaphragm reciprocating swing roller 9 and the six manipulators 10 move synchronously in the first direction. The diaphragm reciprocating swing roller 9 covers the diaphragm on the lifting lamination table 4. At the same time, the six manipulators 10 act synchronously. The manipulators 10 located on the side of the positive electrode sheet conveyor belt 1 and on the left side of the diaphragm reciprocating swing roller 9 respectively transfer the positive electrode sheet on the positive electrode sheet conveyor belt 1 to the positive electrode sheet rotating platform 2, transfer the positive electrode sheet rotated 90° on the positive electrode sheet rotating platform 2 to the positive electrode sheet alignment table 3, and transfer the positive electrode sheet corrected by the positive electrode sheet alignment table 3 to the lifting lamination table 4 for lamination. The manipulators 10 located on the right side of the diaphragm reciprocating swing roller 9 and the side of the negative electrode sheet conveyor belt 7 respectively move to the negative electrode sheet alignment table 5, the negative electrode sheet rotating platform 6 and the negative electrode sheet conveyor belt 7 to transfer the negative electrode sheet. On the contrary, when the controller controls the linear motor to drive the movers 8 to move synchronously in the second direction opposite to the first direction, the diaphragm reciprocating swing roller 9 and the six manipulators 10 move synchronously in the second direction, and its working process is similar and will not be elaborated here.

[0037] In summary, by canceling the rotating mechanism on the traditional manipulator, and at the same time, adding the positive electrode sheet rotating platform between the positive electrode sheet conveyor belt and the positive electrode sheet alignment table, adding the negative electrode sheet rotating platform between the negative electrode sheet conveyor belt and the negative electrode sheet alignment table, and equidistant design between the seven stations, with every two manipulators sharing one mover, the following technical effects can be achieved:

[0038] 1. The number of movers is reduced from five to three, which can reduce costs and improve energy efficiency;

[0039] 2. The number of displacements between the positive electrode conveyor belt and the negative electrode conveyor belt is increased from four sections to six sections, that is, the distance between each station becomes smaller, and the stroke of each displacement of the positive electrode sheet and the negative electrode sheet becomes smaller, thereby shortening the required time and improving the lamination efficiency of the equipment.

[0040] The above are only the preferred embodiments of the present utility model, and do not thus limit the patent scope of the present utility model. Any equivalent structural transformation made under the concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields shall be included within the patent protection scope of the present utility model.
