The invention provides a diaphragm stacking method.

In an embodiment of the present invention, referring to fig. 1, the membrane stacking method is used for a membrane stacking system, the membrane stacking system includes a material transporting mechanism, a stacking table 10, a reversing roller assembly 20, a membrane pressing member, and a membrane cutter 40, and the membrane stacking method includes:

s10, controlling a material conveying mechanism to provide a positive plate 61 and a negative plate 62, discharging a diaphragm 90 from the reversing roller assembly 20, and stacking the positive plate 61, the negative plate 62 and the diaphragm 90 on a stacking table 10 to form a plate group;

s20, controlling a diaphragm pressing piece to press the diaphragm 90 against the discharge end of the reversing roller assembly 20;

s30 controls the diaphragm cutter 40 to cut the diaphragm 90 at a position where the diaphragm 90 is between the diaphragm pressing member and the pole piece group.

In step S10, the material transporting mechanism provides the positive electrode sheet 61 and the negative electrode sheet 62, the reversing roller cooperates with the material transporting mechanism, and the separator 90 is provided between the positive electrode sheet 61 and the negative electrode sheet 62 while the material transporting mechanism provides the positive electrode sheet 61 and the negative electrode sheet 62 onto the stacking table 10. The formed pole piece group is the pole piece group required by the battery core, and the pole piece group can be packaged in the battery core in the manufacturing process of the battery.

After the membrane 90 is stacked once, i.e. after the pole piece assembly is formed, the membrane 90 needs to be cut so that the pole piece assembly can be removed from the stacking table 10 in the subsequent process. In cutting the membrane 90, the prior art typically cuts the membrane 90 directly, such that the tension present on the membrane 90 itself is suddenly reduced, which can easily cause the membrane 90 to buckle. In the method for stacking the diaphragms according to the present invention, in step S20, the diaphragm pressing member is controlled to press the diaphragm 90 against the discharge end of the reversing roller assembly 20, so that in step S30, when the cutter is controlled to cut off the diaphragm 90, the tension of the diaphragm 90 upstream of the reversing roller assembly 20 is unchanged, and wrinkling is avoided. So that the flatness of the separator 90 is improved.

Referring to fig. 1, optionally, the method of stacking the diaphragm further includes, after controlling the diaphragm cutter 40 to sever the diaphragm 90 at a position where the diaphragm 90 is between the diaphragm pressing member and the pole piece group:

s40, controlling a material conveying mechanism to take down the pole piece group from the stacking table 10;

s50, controlling the stacking table 10 to move towards the direction approaching to the reversing roller assembly 20, so that the distance between the stacking table 10 and the reversing roller assembly 20 in the vertical direction is smaller than the length of the free end 91 of the diaphragm 90;

s60 controls the reversing roller assembly 20 to move from the edge of the stacking table 10 toward the center of the stacking table 10.

After the pole piece is taken down from the stacking table 10 by the material conveying mechanism, the next membrane stacking can be started. Because the positive electrode sheet 61 and the negative electrode sheet 62 have a certain thickness when stacking the separator, the stacking table 10 descends by the thickness of one sheet in the process of stacking one sheet each time, so that the distance between the uppermost end of the sheet and the reversing roller assembly 20 is kept stable, and the separator 90 is ensured to be flat. When the pole piece group is removed, the stacking table 10 needs to be lifted to restore the distance between the stacking table 10 and the reversing roller assembly 20, so that the next membrane stacking is started.

The stacking table 10 moves towards the direction approaching the reversing roller assembly 20, namely, the stacking table 10 is lifted; the stacking table 10 can be lifted up along a straight line in the vertical direction, which is suitable for the diaphragms 90 at the front and rear ends of the pole piece group to be positioned at the same side of the pole piece group, that is, as shown in fig. 5, the front and rear ends of the diaphragms 90 of the pole piece group in fig. 5 are positioned at the left side of the pole piece group. The movement of the stacking table 10 to the direction approaching to the reversing roller can be firstly horizontal translation and then ascending; or ascending and then horizontally translating; or while ascending, i.e. ascending obliquely, this applies to the diaphragms 90 at the front and rear ends of the pole piece set being on different sides of the pole piece set.

During the ascent of the stack 10, the free end 91 of the membrane 90, i.e. the membrane 90 downstream of the reversing roller assembly 20 and the membrane pressing member after the membrane 90 has been cut, naturally sags under the force of gravity. Since the distance between the stacking table 10 and the reversing roller assembly 20 in the vertical direction is smaller than the length of the free end 91 of the diaphragm 90, when the reversing roller assembly 20 moves from the edge of the stacking table 10 to the center of the stacking table 10, the diaphragm 90 naturally abuts against the surface of the stacking table 10, so that the next stacking of the diaphragms is facilitated. The diaphragm 90 naturally abuts against the surface of the stacking base 10, that is, the state shown in fig. 7. The diaphragm 90 is naturally attached to the surface of the stacking table 10, and no extra step or execution device is needed to attach the diaphragm 90 to the surface of the stacking table 10, so that the diaphragm stacking efficiency can be improved.

Referring to fig. 1, optionally, the membrane stacking system further includes a pressing knife 70, and the membrane stacking method further includes, after controlling the reversing roller assembly 20 to move from the edge of the stacking table 10 toward the center of the stacking table 10:

s70, controlling the pressing knife 70 to press the free end 91 of the diaphragm 90 against the surface of the stacking table 10;

s80 controls the pressing of the diaphragm member away from the diaphragm 90.

After the step S60 is completed, the diaphragm 90 is naturally attached to the surface of the stacking table 10, and in the step S70, the diaphragm 90 is further pressed against the surface of the stacking table 10 by the pressing blade 70, so that the diaphragm 90 is prevented from deviating from the preset position. After the diaphragm 90 is pressed by the pressing knife 70, the diaphragm pressing piece is controlled to be far away from the diaphragm 90, so that after the diaphragm 90 is cut off, the diaphragm 90 is always pressed on the reversing roller assembly 20 by the diaphragm pressing piece, and the free end 91 of the diaphragm 90 is prevented from shifting to a preset position under the influence of environmental factors, and the accuracy of diaphragm stacking is prevented from being reduced; it is also possible to maintain sufficient tension on the diaphragm 90 upstream of the reversing roller assembly 20 at all times to remain flat.

Referring to fig. 2, optionally, the diaphragm pressing member is configured as a pressing block 30, the reversing roller assembly 20 includes a discharge reversing roller 21, the diaphragm stacking system further includes a pressing block 30 driving mechanism, and controlling the diaphragm pressing member to press the diaphragm 90 against the discharge end of the reversing roller assembly 20 includes:

s21, controlling a pressing block 30 driving mechanism to drive the pressing block 30 to press the diaphragm 90 against the discharging reversing roller 21.

The pressing block 30 is matched with the discharging reversing roller 21, so that the fixing effect on the diaphragm 90 is better.

The present invention also proposes a diaphragm stacking system, referring to fig. 3 to 9, comprising a controller for:

the material conveying mechanism is controlled to provide a positive plate 61 and a negative plate 62, the reversing roller assembly 20 outputs a diaphragm 90, and the positive plate 61, the negative plate 62 and the diaphragm 90 are stacked on the stacking table 10 to form a plate group;

the diaphragm 90 is pressed against the discharge end of the reversing roller assembly 20 by the control diaphragm pressing member;

the diaphragm cutter 40 is controlled to cut the diaphragm 90 at a position where the diaphragm 90 is between the diaphragm pressing member and the pole piece group.

It should be noted that the above explanation of the implementation and the advantageous effects of the membrane stacking method is also applicable to the corresponding embodiment of the membrane stacking system, and will not be expanded in detail here to avoid redundancy.

The material handling mechanism may be a robotic arm by which the membrane 90 is transported to the stacking station 10; the transporting rail may be matched with a push rod, the transporting rail transports the positive electrode plate 61 or the negative electrode plate 62 to the side surface of the stacking table 10, and the push rod pushes the positive electrode plate 61 or the negative electrode plate 62 to the stacking table 10. The reversing roll assembly 20 may include a plurality of reversing rolls, such as in the embodiment shown in fig. 3, the reversing roll assembly 20 having four reversing rolls with a septum gap formed therebetween, the septum 90 passing between the reversing rolls; the four reversing rolls cooperate to stabilize the direction of the exiting diaphragm. The reversing roller assembly 20 is adapted to move back and forth on both sides of the stack 10, e.g. in fig. 8 the reversing roller assembly 20 moves to the right of the stack 10, whereas in fig. 3 the reversing roller moves to the left of the stack 10. The reversing rollers move back and forth on both sides of the stacking table 10 to stack the separator 90 in a zigzag shape between the positive electrode sheet 61 and the negative electrode sheet 62 and separate the positive electrode sheet 61 from the accessory sheet.

The diaphragm pressing member may be a cylindrical pressing roller and the diffraction direction is the same as the direction changing roller, so that the diaphragm pressing member can be prevented from pressing the diaphragm 90. The diaphragm member surface may be provided with a high coefficient of friction material, such as silicone or rubber, to enhance the securement of the diaphragm 90.

In the state shown in fig. 3, the pole piece group has been laminated. The process of fig. 3 to 4, i.e. the process of pressing the diaphragm 90 against the discharge end of the reversing roller assembly 20 by the controller under control of the diaphragm pressing member; figure 5 shows the controller in controlling the diaphragm cutter 40 to sever the diaphragm 90 at a position where the diaphragm 90 is between the diaphragm pressing member and the pole piece set.

As shown in fig. 3, the stacked diaphragm system may also include a feed roller 80 to form a feed belt path for the diaphragm 90.

Referring to fig. 3-9, optionally, after the controller is used to control the diaphragm cutter 40 to sever the diaphragm 90 at a position where the diaphragm 90 is between the diaphragm pressing member and the pole piece set, the controller is further configured to:

controlling a material conveying mechanism to take down the pole piece group from the stacking table 10;

controlling the movement of the stacking table 10 in a direction approaching the reversing roller assembly 20, so that the distance between the stacking table 10 and the reversing roller assembly 20 in the vertical direction is smaller than the length of the free end 91 of the diaphragm 90;

the reversing roller assembly 20 is controlled to move from the edge of the stack 10 toward the center of the stack 10.

The material conveying mechanism can take off the pole piece group through a mechanical arm, and can also clamp and take off the pole piece group through a clamp 50 as shown in fig. 5.

The state shown in fig. 5 is changed to the state shown in fig. 7, namely, the controller is in the process of controlling the material conveying mechanism to take down the pole piece group from the stacking table 10; in the state shown in fig. 7, the stacking table 10 has been moved under the control of the controller in a direction approaching the reversing roller assembly 20 such that the distance between the stacking table 10 and the reversing roller assembly 20 in the vertical direction is smaller than the length of the free end 91 of the diaphragm 90, and the reversing roller assembly 20 is also moved by the edge of the stacking table 10 in the center direction of the stacking table 10 under the control of the controller, it can be seen that the diaphragm 90 naturally abuts against the surface of the stacking table 10.

Referring to fig. 7 and 8, optionally, the membrane stacking system further comprises a presser blade 70, and after the controller is configured to control the reversing roller assembly 20 to move from the edge of the stacking table 10 toward the center of the stacking table 10, the controller is further configured to:

the control pressing knife 70 presses the free end 91 of the diaphragm 90 against the surface of the stacking table 10;

the control presses the diaphragm member away from the diaphragm 90.

The pressing knives 70 can be used for pressing the positive electrode plate 61 or the negative electrode plate 62, that is, as shown in fig. 3, the two pressing knives 70 press the electrode plates at two ends of the electrode plate group to fix the electrode plates, thereby improving lamination precision. The hold down knife 70 may be used to hold down the diaphragm 90 to secure the diaphragm 90 against wrinkling or shifting of the diaphragm 90. As shown in fig. 7, the controller controls the presser blade 70 to press the free end 91 of the diaphragm 90 against the surface of the stack 10, thereby fixing the diaphragm 90. As shown in fig. 8, i.e., the controller controls the distance of the pressure diaphragm member from the diaphragm 90, at which point the reversing roller assembly 20 needs to be released from the new diaphragm 90, the distance of the pressure diaphragm member from the diaphragm 90 allowing the diaphragm 90 to be expelled from the reversing roller assembly 20. When the diaphragm 90 is laid at the position of the second presser 70, as shown in fig. 8, the two pressers 70 can be pressed against the diaphragm 90 at the same time, thereby improving the fixing effect on the diaphragm 90.

Referring to fig. 6, optionally, the membrane pressing member is configured as a pressing block 30, the reversing roller assembly 20 includes a discharge reversing roller 21, and the membrane stacking system further includes a pressing block 30 driving mechanism, and the controller is configured to:

the driving mechanism of the pressing block 30 is controlled to drive the pressing block 30 to press the diaphragm 90 against the discharging reversing roller 21.

The pressing block 30 is abutted against the discharging reversing roller 21, the pressing block 30 can be a pressing plate with the extending direction being the same as that of the discharging reversing roller 21, and the edge of the pressing block 30 is abutted against the discharging reversing roller 21 so as to improve the pressure of the pressing plate on the diaphragm 90 and the fixing effect on the diaphragm 90.

Referring to fig. 3, alternatively, the diaphragm pressing member is drivingly connected to the reversing roller assembly 20. Because the diaphragm pressing member and the reversing roller assembly 20 follow up in the moving process of the reversing roller assembly 20, the diaphragm pressing member is in driving connection with the reversing roller assembly 20, so that the diaphragm pressing member can be conveniently controlled, and the diaphragm pressing member is prevented from being accidentally separated from the reversing roller assembly 20, and the fixing effect on the diaphragm 90 is lost.

The invention also provides a readable storage medium, wherein the readable storage medium stores a control program of the membrane stacking system, and the control program of the membrane stacking system realizes the steps of the membrane stacking method when being executed by a processor. The storage medium may be a high-speed RAM memory or a stable memory (non-volatile memory), such as a disk memory.
