Description
Technical Field
[0001] The utility model relates to the field of lamination machines, in particular to a lamination diaphragm folding and reversing mechanism. Background Art
[0002] At present, stacking machines are widely used in the new energy industry. Among them, stacking machines without tail roll requirements are more common. For stacking processing without tail roll requirements, manual operation is usually used to cut the diaphragm first, and then manually lay the diaphragm on the stacking table for positioning. The manual laying and positioning of the diaphragm on the stacking table can easily cause diaphragm positioning deviation, inaccurate positioning, and uneven and loose edge wrapping of the first electrode sheet. It may even cause the edge wrapping of the first negative electrode sheet to be cut, ultimately resulting in a high defective rate of the battery cell. At the same time, stacking machines without tail roll processing requirements take a long time to complete the diaphragm reversing operation, which makes it have the disadvantages of time-consuming reversing, long production cycle and low reversing efficiency. Summary of the Invention
[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a laminated diaphragm folding and reversing mechanism.
[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions: the laminated diaphragm folding and reversing mechanism includes a first linear sliding module and a second linear sliding module which are balanced, a movable base plate is provided across the first linear sliding module and the second linear sliding module, a first screw rod kit is provided between the first linear sliding module and the second linear sliding module, the first screw rod kit is connected to a first drive unit, the first screw rod kit is connected and installed to the movable base plate, a diaphragm reversing component and a laminate device are respectively provided on the movable base plate, and a diaphragm cutting component is provided above the laminate device.
[0005] By adopting the above-mentioned technical solution, the lamination device moves back and forth under the drive of the first drive unit to longitudinally lay the diaphragm on the adjacent stacked pole pieces on the lamination device, and the diaphragm cutting component is used to cut the diaphragm connecting the battery cell and the diaphragm roll. When the diaphragm at the front end of the diaphragm roll is transferred to the side of the diaphragm reversing component facing the lamination device through the diaphragm reversing component, the diaphragm reversing component sucks the diaphragm at the front end of the diaphragm roll and presses it to the side of the lamination device. Because the first drive unit can drive the movable base plate to move back and forth through the first screw rod kit, the lamination device can move back and forth with the movement of the movable base plate. The first drive unit drives the lamination device and the diaphragm reversing component to move together in the direction of the lamination device facing the diaphragm reversing component to complete the diaphragm flipping from the diaphragm reversing component and laying it on the lamination device, which completes the positioning of the diaphragm on the lamination device. When each electrode is placed on the surface of the top diaphragm of the stacking device, the first drive unit drives the stacking device to move in the direction opposite to the last movement direction to flip the diaphragm longitudinally, so that it can automatically complete the laying of diaphragms for adjacent stacked electrode pieces on the stacking device. At the same time, each time a electrode piece is placed on the stacking device, the height of the electrode piece will be lowered to keep each electrode piece at the top of the stacking device always at the same height.
[0006] Furthermore, the diaphragm reversing component includes a reversing vertical plate installed on the movable base plate, a third linear sliding module and a second driving unit are provided on one side of the reversing vertical plate, a lifting and moving vertical plate is provided on the third linear sliding module, the second driving unit is connected to the lifting and moving vertical plate, and the second driving unit drives the lifting and moving vertical plate to move up and down on the third linear sliding module; a lifting and moving horizontal plate is provided on the lifting and moving vertical plate, a fourth linear sliding module and a third driving unit are provided on the lifting and moving horizontal plate, a horizontal moving horizontal plate is provided on the fourth linear sliding module, the third driving unit is connected to the horizontal moving horizontal plate, and the third driving unit drives the horizontal moving horizontal plate to move back and forth on the fourth linear sliding module; a diaphragm suction plate is provided on one side of the horizontal moving horizontal plate, and a diaphragm guide plate is provided on the horizontal moving horizontal plate.
[0007] By adopting the above technical solution, after the stacking device reciprocates to complete the placement of the diaphragms on the adjacent stacked electrode sheets, since the battery cells are still connected to the diaphragms, the first drive unit drives the stacking device and the diaphragm reversing component to move in a direction facing the stacking device, so that the diaphragms are firmly placed on the diaphragm guide plates. The diaphragm cutting component moves downward to blow air into the diaphragm between the diaphragm reversing component and the stacking device, thereby cutting the diaphragm. The air blowing can blow the front end of the cut diaphragm roll onto the side of the diaphragm suction plate, which then absorbs the front end of the cut diaphragm. The second and third drive units cooperate to drive the diaphragm suction plate to press the front end of the diaphragm against the side of the stacking device, thereby securing the diaphragm at the front end of the diaphragm roll. When the first drive unit drives the stacking device and the diaphragm reversing component to move in a direction facing the diaphragm reversing component, the diaphragm placed on the diaphragm guide plates is flipped up and placed on the stacking device, completing the diaphragm reversal.
[0008] Furthermore, one side surface of the diaphragm suction plate is provided with more than one suction hole.
[0009] Furthermore, the upper surface of the diaphragm suction plate and the upper surface of the diaphragm guide plate are in the same horizontal plane, one end of the diaphragm guide plate is extended downward to provide a guide plate mounting portion, the diaphragm guide plate is connected and installed with the diaphragm suction plate through the guide plate mounting portion, and the other end of the diaphragm guide plate is extended downward to provide an inclined plate.
[0010] By adopting the above technical solution, the design of the inclined plate makes it have a certain angle with the diaphragm, and the diaphragm flips up and changes direction on the diaphragm guide plate without sticking to the inclined plate, which makes the action of flipping the diaphragm simple and convenient, and the diaphragm guide plate will not hook the diaphragm and cause the diaphragm to tear.
[0011] Furthermore, the diaphragm cutting component includes a film cutting vertical plate, on which a fifth linear sliding module and a sixth linear sliding module are provided, the fifth linear sliding module and the sixth linear sliding module are arranged in a balanced manner, a cutter mounting seat is connected between the fifth linear sliding module and the sixth linear sliding module, a cutter is installed on the cutter mounting seat, a blowing seat is provided on the side of the cutter mounting seat, a fourth drive unit is provided on the film cutting vertical plate, and the fourth drive unit is drive-connected to the cutter mounting seat.
[0012] Furthermore, the blowing seat and the cutter are arranged in a balanced manner, and the blowing seat is provided with more than one blowing hole.
[0013] Furthermore, the lamination device includes a lamination base plate, a lamination supporting assembly is provided on the lamination base plate, and a first lamination assembly and a second lamination assembly are provided on both sides of the lamination supporting assembly.
[0014] By adopting the above-mentioned technical solution, the first pressing assembly presses and fixes one end or one side of the topmost electrode sheet of the stack support assembly. When the sixth drive unit drives the second pressing assembly in the stack device to move toward the first pressing assembly, one side of the diaphragm is flipped up and reversed, and laid on the surface of the topmost electrode sheet. When the sixth drive unit drives the stack device to move along the first pressing assembly toward the second pressing assembly, the other end or the other side of the diaphragm is flipped up and reversed, and laid on the surface of the topmost electrode sheet. When the first pressing assembly and the second pressing assembly move downward synchronously, they can respectively press and fix the diaphragms that have completed the reversal on both ends or both sides of the electrode sheet, so as to ensure that the diaphragm wraps the electrode sheet flat and tightly, and avoid the phenomenon that the diaphragm cutting component easily cuts the edge of the diaphragm of the first negative electrode sheet when cutting the diaphragm.

[0016] By adopting the above-mentioned technical solution, as the pole pieces are stacked on the stacking table, when the height of the pole piece stacked on the top of the stacking table exceeds a predetermined height, the fifth drive unit drives the stacking lifting frame to descend on the seventh linear sliding module and the eighth linear sliding module through the second screw rod kit, and the stacking table is lowered as the stacking lifting frame is lowered, so that the top pole piece on the stacking table can always be maintained at the same height.

The sixth drive unit drives the first fixed lateral moving seat and the second fixed lateral moving seat to move towards each other on the tenth linear sliding module and the eleventh linear sliding module through the pulley assembly to simultaneously flip up and reverse the left and right ends of the diaphragm, so that it can automatically hem the two ends of the pole piece placed on the surface of the diaphragm; when the eighth drive unit and the ninth drive unit respectively drive the first pressure plate and the second pressure plate to descend, they press and fix the pole piece on the top of the stacking table to avoid uneven and loose hemming of the pole piece and the easy cutting of the hemming part of the pole piece and diaphragm. On the contrary, the sixth drive unit drives the first fixed transverse moving seat and the second fixed transverse moving seat through the pulley kit to separate from each other synchronously on the tenth linear sliding module and the eleventh linear sliding module. At the same time, the eighth drive unit and the ninth drive unit respectively drive the first pressure plate and the second pressure plate to rise and reset to exit or release the pressure on the pole piece.

[0022] Compared with the prior art, the present invention has the following advantages: a diaphragm reversing component and a lamination device are provided on a movable base plate. The diaphragm reversing component cooperates with the lamination device and, driven by a first drive unit, drives the diaphragm to isolate and repeatedly reverse the adjacent stacked pole pieces on the lamination device. Furthermore, a diaphragm cutting component is provided above the lamination device. The first drive unit drives the lamination device and the diaphragm reversing component to move together in a direction facing the lamination device so that the diaphragm can be laid on the diaphragm guide plate. The diaphragm cutting component cuts the diaphragm and blows air through the blowing holes to blow the cut diaphragm at the front end of the diaphragm roll onto the side of the diaphragm suction plate in the diaphragm reversing component. The diaphragm suction plate suctions and secures the diaphragm through the suction holes. When the second and third drive units cooperate to drive the diaphragm suction plate toward the lamination device, the sucked diaphragm is pressed against the side of the lamination device to secure the diaphragm at the front end of the diaphragm roll. When the first drive unit drives the stacking device and the diaphragm reversing component to move along the direction of the stacking device facing the diaphragm reversing component so that the diaphragm laid on the diaphragm guide plate is flipped up and laid on the stacking device, the reversal of the diaphragm is completed. The diaphragm is reversed when one end of the diaphragm is pressed against the side of the stacking device to ensure that the reversal of the diaphragm will not be offset.

The above-mentioned drive units are not limited to this, and all drive sources that can drive the components connected thereto to perform linear reciprocating motion can be attempted to use.
[0045] In one embodiment, the structural design principle of the laminated diaphragm folding and reversing mechanism is as follows: a diaphragm reversing component 6 and a laminate device 7 are respectively provided on the movable base plate 3, and a diaphragm cutting component 8 is provided above the laminate device 7. When the first drive unit 5 drives the laminate device 7 and the diaphragm reversing component 6 to move together in the direction of the laminate device 7 facing the diaphragm reversing component 6, the inertia or driving force generated can drive the diaphragm laid on the diaphragm reversing component 6 to flip up and turn longitudinally and lay on the laminate device 7. After each electrode is placed on the diaphragm surface on the stacking device 7, the first drive unit 5 drives the stacking device 7 to move in the opposite direction of the previous movement to perform longitudinal flipping and reversing of the diaphragm. At the same time, the fifth drive unit 722 of the stacking support assembly 72 in the stacking device 7 drives the second screw assembly 723 to drive the stacking lifting frame 726 to descend on the seventh linear sliding module 724 and the eighth linear sliding module 725, so that the stacking platform 727 lowers the height of one electrode as the stacking lifting frame 726 descends, so as to keep the top electrode on the stacking platform 727 always at the same height. This cycle is repeated until the diaphragm completes the isolation and repeated reversal of all adjacent electrodes on the stacking device 7, and the stacking of the electrodes reaches the predetermined production quantity, thus completing the production of the battery cell electrodes isolated and stacked by the diaphragm.
[0046] The first film pressing assembly 73 and the second film pressing assembly 74 are respectively provided on both sides of the stacking support assembly 72 of the stacking device 7. When the sixth driving unit 732 in the first film pressing assembly 73 and the second film pressing assembly 74 drives the pulley kit 7393 to rotate forward and reverse, it can drive the first fixed transverse moving seat 7391 and the second fixed transverse moving seat 7392 to move towards or away from each other on the tenth linear sliding module 738 and the eleventh linear sliding module 739 at the same time. When the sixth drive unit 732 drives the first fixed transverse moving seat 7391 and the second fixed transverse moving seat 7392 to approach each other on the tenth linear sliding module 738 and the eleventh linear sliding module 739 through the pulley kit 7393, the left and right sides of the diaphragm can be flipped up and reversed, so that the two sides of the pole piece placed on the diaphragm can be automatically edged; when the eighth drive unit 7396 and the ninth drive unit 7397 respectively drive the first pressure plate 7398 and the second pressure plate 7399 to descend, the diaphragm on both sides of the top pole piece on the stacking table 727 can be pressed and fixed, which avoids the phenomenon of uneven edge wrapping, loose edge wrapping and easy cutting of the edge wrapping of the pole piece diaphragm.
[0047] When the battery cell needs to cut off the diaphragm connected to it, the first drive unit 5 drives the stacking device 7 and the diaphragm reversing component 6 to move together along the diaphragm reversing component 6 in the direction of the stacking device 7. The power energy generated drives the diaphragm to be laid on the diaphragm guide plate 60. The blowing hole 87 in the diaphragm cutting component 8 along with the blowing seat 85 and the cutter 84 along with the cutter mounting seat 83 can move toward the diaphragm along the fifth linear sliding module 81 under the drive of the fourth drive unit 86, so that the downward-moving cutter 84 automatically cuts off the diaphragm, and the downward-moving blowing hole 87 blows air to the diaphragm at the front end of the cut diaphragm roll to blow it to the side of the diaphragm suction plate 69 in the diaphragm reversing component 6. The diaphragm suction plate 69 and the diaphragm guide plate 60 in the diaphragm reversing component 6 move together with the horizontally movable cross plate 68 and can perform linear reciprocating movement on the fourth linear sliding module 66 under the drive of the third drive unit 67, so that the diaphragm suction plate 69 can move closer to the stacking device 7 under the drive of the third drive unit 67; when the diaphragm at the front end of the diaphragm roll is blown to the side of the diaphragm suction plate 69 in the diaphragm reversing component 6, the diaphragm suction plate 69 can use the suction hole 691 set on its side to suck the diaphragm at the front end of the diaphragm roll and, under the drive of the third drive unit 67, can press the diaphragm at the front end of the diaphragm roll to the side of the stacking device 7 to fix the diaphragm at the front end of the diaphragm roll. After the diaphragm connected to the battery cell is cut off by the diaphragm cutting component 8, the finished battery cell can be taken away from the stacking table 727 by a robot for unloading. The first drive unit 5 drives the stacking device 7 and the diaphragm reversing component 6 to move along the stacking device 7 facing the diaphragm reversing component 6 so that the diaphragm laid on the diaphragm guide plate 60 is turned up and laid on the stacking device 7 to complete the reversal of the diaphragm. The front end or end of the diaphragm is pressed against the side of the stacking device 7 to reverse the diaphragm to avoid the reversal of the diaphragm. It ensures that the diaphragm can be accurately positioned on the stacking device 7 to prepare for laying the diaphragm for the stacking sheet of the next battery cell.
[0048] Its overall structural design realizes the ability to use the diaphragm to isolate and automatically and repeatedly reverse the adjacent pole pieces on the stacking device 7, and it can reverse the two sides of the diaphragm separately through the first pressing assembly 73 and the second pressing assembly 74, so as to realize the automatic edging and pressing of the two sides of the pole piece simultaneously. It not only has the advantages of smooth edging, tight edging, precise positioning, high edging efficiency, good edging effect and ensuring high yield rate of battery cells, but also has the advantages of flexible steering operation, high steering efficiency and high steering accuracy for the diaphragm, and the process of repeated steering of the diaphragm and edging of the pole piece does not require manual participation, so that it can effectively solve the current stacking machine structure that requires manual laying of the diaphragm and positioning of the diaphragm on the stacking table, resulting in inaccurate diaphragm positioning, uneven pole piece edging, loose pole piece edging, easy cutting of the pole piece diaphragm edging part, low diaphragm commutation efficiency and low yield rate of finished battery cells.
[0049] The above embodiment is only an example of the present invention and is not intended to limit the implementation and scope of rights of the present invention. Any technical solution that is identical or equivalent to the content described in the claims of the present invention should be included in the protection scope of the present invention.
