Specifically, the diaphragm pressing plate mechanism comprises an upper pressing plate and a lower pressing plate, and a pacifying plate is clamped between the upper pressing plate and the lower pressing plate. The pacifying plate is connected with the lower pressure plate through a synchronizing assembly, and the synchronizing assembly is configured to drive the pacifying plate to be close to or far away from the lower pressure plate when the lower pressure plate moves, so that the pacifying plate and the lower pressure plate form a first interval for the diaphragm to pass through before the lower pressure plate and the upper pressure plate clamp the diaphragm. This enables the membrane to be effectively held by the upper and lower platens by flattening the rolled up membrane through the narrow first gap.
Description

The invention relates to the technical field of battery manufacturing, in particular to a diaphragm pressing plate mechanism and a lamination machine.
Background
In the prior art, after the cell stack is completed, a certain length of membrane (tail membrane for short) is usually pulled out to wind one or more turns around the outer surface of the cell for ending. Specifically, the tail film is required to be pulled out to a certain length in the ending process, pressed by the diaphragm pressing plate mechanism after the diaphragm with a certain length is pulled out, and then gradually fed to one side of the battery cell in the tail film winding process, so that the tail film winding operation is completed by matching with the tail film winding mechanism.
The diaphragm pressing plate mechanism mainly comprises an upper pressing plate, a lower pressing plate and a driving piece, when the battery diaphragm is wound and rolled, the driving piece drives the upper pressing plate and the lower pressing plate to be opened, a discharging manipulator penetrates through the interval between the lower pressing plate and the upper pressing plate to reach the position of the lamination discharging position for grabbing the battery core, the battery core is transferred to a tail film winding position, and in the process, the diaphragm is pulled out for a certain length for winding and wrapping the periphery of the battery core; cutting the diaphragm in a hot melting mode after the diaphragm is pulled out for a specified length, moving the cut diaphragm along with the battery cell, and pressing the tail end of the diaphragm by the diaphragm pressing plate mechanism when the tail end of the diaphragm moves to a position, close to the tail film winding position, of the diaphragm pressing plate mechanism; when in winding, the diaphragm pressing plate mechanism and the diaphragm winding mechanism are close to each other along with the shortening of the tail film until the tail film winding is completed.
The diaphragm pressing plate mechanism has the following problems: after the diaphragm is cut by the thermal fuse, the tail end of the diaphragm is affected by tension and high temperature to turn over, so that the upper pressing plate and the lower pressing plate cannot press the tail end of the diaphragm during winding, and the tail film winding at the back is affected. To solve the problem, in the prior art, a vacuum adsorption hole is formed in a lower pressing plate so as to adsorb a diaphragm by utilizing negative pressure guided to the vacuum adsorption hole, so that the diaphragm pressing plate mechanism can effectively and timely press the tail end of the diaphragm during winding. However, the rolled membrane tail end is easy to break vacuum, and the vacuum adsorption holes cannot effectively adsorb the membrane tail end, so that the problem of timely compression of the membrane cannot be effectively solved.

The embodiment of the invention provides a diaphragm pressing plate mechanism and a lamination machine, which can smooth a cut and rolled diaphragm, so that an upper pressing plate and a lower pressing plate can press the diaphragm better.
Referring to fig. 1-3, an embodiment of the present invention provides a diaphragm pressing plate mechanism including an upper pressing plate 200 and a lower pressing plate 300, with a pacifier plate 400 interposed between the upper pressing plate 200 and the lower pressing plate 300. The tending plate 400 is connected to the lower platen 300 through a synchronizing assembly 500, the synchronizing assembly 500 being configured to bring the tending plate 400 toward or away from the lower platen 300 when the lower platen 300 is moved, so that the tending plate 400 and the lower platen 300 form a first space through which a diaphragm passes before the lower platen 300 and the upper platen 200 clamp the diaphragm, or so that the tending plate 400 and the lower platen 300 form a second space through which a discharging robot passes when the lower platen 300 and the upper platen 200 are opened.
In this embodiment, when the feeding manipulator needs to grab the wound electrical core to the winding station, the upper platen 200 is lifted, the lower platen 300 is lowered, the upper platen 200 and the lower platen 300 are far away from each other, and the synchronization assembly 500 drives the smoothing plate 400 to lift away from the lower platen 300, so that the smoothing plate 400 and the lower platen 300 form a second interval for the feeding manipulator to pass through. After the discharging manipulator grabs the wound battery core to the winding station, the battery core pulls the diaphragm to a specified length, and the thermal fuse cuts the diaphragm. The lower pressure plate 300 rises to enable the synchronous assembly 500 to drive the smoothing plate 400 to be close to the lower pressure plate 300, the smoothing plate 400 and the lower pressure plate 300 form a first interval, the cut diaphragm continuously moves along with the battery cell, the diaphragm passes through the first interval in the process of being pulled, the smoothing plate 400 smoothes the curled diaphragm, then the upper pressure plate 200 descends, the upper pressure plate 200 and the lower pressure plate 300 jointly compress the diaphragm, the diaphragm is better clamped, and the diaphragm is better wound to the battery cell.
In this embodiment, the first interval is between 0.1mm and 1.0mm, preferably 0.5mm, so that the purpose of smoothing the diaphragm can be achieved without affecting the normal passage of the diaphragm.
In this embodiment, the smoothing plate 400 is a capillary plate, which is low in cost and easy to obtain. Of course, in other alternative embodiments, the smoothing plate 400 may be made of other materials, which is not limited herein.
With continued reference to fig. 3, in an embodiment, in particular, the synchronization assembly 500 includes a pulley 510 and a timing belt 520. The pulley 510 is fixed above the upper platen 200. The first end of the timing belt 520 is connected to the leveling plate 400, and the second end of the timing belt 520 is reversed by the pulley 510 and then connected to the lower platen 300.
Thus, when the lower pressure plate 300 is raised, the second end of the timing belt 520 is raised along with the lower pressure plate 300, and the first end of the timing belt 520 is lowered, so that the smoothing plate 400 connected to the first end of the timing belt 520 is lowered; when the lower platen 300 descends, the second end of the timing belt 520 descends along with the lower platen 300, and the first end of the timing belt 520 ascends, so that the smoothing plate 400 connected to the first end of the timing belt 520 ascends. That is, when the lower platen 300 is raised, the smoothing plate 400 is lowered; when the lower platen 300 descends, the timing belt 520 ascends.
With continued reference to FIG. 3, in an embodiment, the synchronization assembly 500 is two, separated on either side of the smoothing plate 400. Thereby, centering the relevant driving structures of the upper and lower platens 200 and 300 is facilitated by leaving an upper space of the pacifier plate 400. At the same time, the smoothness of the stroke plate 400 moving up and down with the lower platen 300 is ensured.
In other embodiments, one synchronization assembly 500 may alternatively be employed, with the synchronization assembly 500 being disposed to the left, right, or centered on the pacifier plate 400. When one synchronizing assembly 500 is used and the synchronizing assembly 500 is provided on one side of the smoothing plate 400, a sliding guide structure is provided on the side of the smoothing plate 400 where the synchronizing assembly 500 is not provided, thereby ensuring that smooth movement of the smoothing plate 400 can be maintained even when a single synchronizing assembly 500 is used. When the single synchronizing assembly 500 is disposed at the middle of the tending plate 400, sliding guide structures are disposed at both sides of the tending plate 400.
Preferably, in the present embodiment, the synchronizing assembly 500 further includes an elastic member 123, and the elastic member 123 is configured to apply an elastic force to the leveling plate 400 when the lower pressure plate 300 moves toward the upper pressure plate 200, so that the leveling plate 400 approaches the lower pressure plate 300, thereby forming a first space between the leveling plate 400 and the lower pressure plate 300 through which the diaphragm passes.
In the case that the elastic member 123 is not provided, when the pacifier 400 moves upward along with the descent of the lower platen 300, the synchronous belt 520 is straightened, and the synchronization assembly 500 can drive the pacifier 400 to follow normally; when the lower platen 300 is lifted, the external force corresponding to one end of the synchronous belt 520 disappears, the tension of the synchronous belt 520 can be straightened only by the gravity of the flat platen 400 at the other end, if the weight of the flat platen 400 is insufficient, the synchronous belt 520 can not be effectively straightened easily, and thus, when the lower platen 300 is lifted down next time, the flat platen 400 can not be driven to move upwards in time, the flat platen 400 and the lower platen 300 are stretched, and the risk of interference between the flat platen 400 and the blanking manipulator is brought. Moreover, the leveling plate 400 is also blocked by the synchronous belt 520 due to gravity descending, so that the leveling plate 400 cannot be matched with the lower pressing plate 300 to form a narrow first interval rapidly, and the leveling effect of the leveling plate 400 is affected.
Based on this, through setting up the elastic member 123, the elastic member 123 stores energy when holding down plate 300 and smooth board 400 are opened relatively to release elastic potential energy when holding down plate 300 and top board 200 are close to each other, thereby apply decurrent elastic force to smooth board 400, in order to ensure to smooth board 400 can be close to holding down plate 300 fast in order to accomplish smooth effect, can take up hold of the hold-in range 520 fast simultaneously, guarantee the transmission effect of hold-in range 520.
The elastic member 123 may be charged in a compressed or stretched form.
Specifically, the elastic member 123 may be disposed between the lower platen 300 and the leveling plate 400, and when the lower platen 300 descends, the leveling plate 400 is pulled by the timing belt 520 to move upward, thereby realizing the opening of the lower platen 300 and the leveling plate 400, and at this time, the elastic member 123 is stretched to store elastic potential energy; when the lower pressure plate 300 rises upwards, the pulling force exerted by the lower pressure plate 300 on the elastic member 123 is reduced or even eliminated, and at this time, the stretched elastic member 123 retracts to pull the pacifier 400 to descend close to the lower pressure plate 300, so that the pacifier 400 and the lower pressure plate 300 form a first interval to pacify the curled portion of the diaphragm tail before being close to the upper pressure plate 200 to clamp the diaphragm, so that the upper pressure plate 200 can quickly and effectively press the diaphragm tail, and convenience is provided for the diaphragm hand tail roll.
The elastic member 123 may be disposed above the leveling plate 400, and in this case, the elastic member 123 is stored energy in a compressed form. Specifically, the upper end of the elastic member 123 is fixed with respect to the pacifier plate 400 such that the lower end of the elastic member 123 is crimped on the pacifier plate 400. When the lower pressure plate 300 descends, the leveling plate 400 is pulled by the timing belt 520 to move upward, so that the leveling plate 400 presses the elastic member 123, and the elastic member 123 is compressed to store elastic potential energy; when the lower platen 300 moves upward, the tension applied by the synchronous belt 520 to the leveling plate 400 is reduced or even eliminated, and the upper end of the elastic member 123 is fixed, at this time, the elastic member 123 can release elastic potential energy downward, so as to drive the leveling plate 400 to move downward, approach the lower platen 300 and form a first interval with the lower platen 300.
Referring to fig. 1 and 3, in the present embodiment, the elastic member 123 is employed to be disposed above the smoothing plate 400.
Further, in order to enable adjustment of the compression amount of the elastic member 123 to meet the demands of different elasticity of the different smoothing plates 400. With continued reference to fig. 1 and 3, in the present embodiment, a rod 121 is further disposed above the leveling plate 400, and a first adjusting member 124 is disposed on the rod 121, and an upper end of the elastic member 123 abuts against the first adjusting member, where the first adjusting member 124 is configured to be movable along the rod 121 and in locking relation with the rod 121, so as to adjust the compressed amount of the elastic member 123, and thus adjust the elastic force of the elastic member 123 applied to the leveling plate 400. Specifically, after the first interval between the pacifier plate 400 and the lower pressure plate 300 is fixed, when the first adjuster 124 moves downward (i.e., approaches the pacifier plate 400), the elastic member 123 is compressed more, the larger the reaction force it exerts on the pacifier plate 400, i.e., the larger the elastic force provided to the pacifier plate 400, so that the pacifier plate 400 can better maintain the interval width with the lower pressure plate 300; conversely, the first regulating member 124 moves upward, the space length side length of the elastic member 123 is deformed, the amount of compressed space is reduced, and the elastic force provided to the pacifier 400 is reduced.
The elastic member 123 may be provided in a hollow shape to be directly sleeved on the rod 121, thereby reducing difficulty in installation of the elastic member 123 and enabling the elastic member 123 to apply elastic force to the smoothing plate 400 along the rod 121.
The elastic member 123 may be a structural member capable of elastic deformation, such as a spring or a rubber column, and a metal spring is preferably used as the elastic member 123.
The locking structure between the first adjusting member 124 and the rod 121 may be a screw structure, a fastening structure, a clasping structure, or the like. For ease of implementation, a threaded configuration is preferred. The engaging structure may be an engaging structure formed by an elastic protrusion and a groove, for example, an elastic protrusion is disposed on the first adjusting member 124, a slot hole is disposed on the rod 121, when the first adjusting member 124 needs to be moved, the elastic protrusion is moved out of the slot hole, and after the first adjusting member 124 is adjusted in place, the elastic protrusion automatically pops up and is engaged into the slot hole; the clamping structure can also be a hard limiting structure, such as a back-off and a groove with an inclined plane, and the holding structure can be a clamping structure similar to a clip, and can also be a spanner-button type or knob type locking structure (see the rod fastening structure of the existing mop telescopic rod).
It should be noted that the above is merely an example of the locking structure between the first adjusting member 124 and the rod member 121, and the locking structure is not limited to the first adjusting member 124 and the rod member 121.
Still further, with continued reference to fig. 1 and 3, in this embodiment, the lower end of the rod 121 slides through the pacifier plate 400, the lower plate 300 is provided with a second adjuster 310, the lower end of the rod 121 is inserted through the pacifier plate 400 onto the second adjuster 310, and the second adjuster 310 is configured to move along the rod 121 and into locking relationship with the rod 121. Thus, the distance of the first interval between the lower pressure plate 300 and the smoothing plate 400 may be adjusted by adjusting the position of the second adjusting member 310 on the lever 121.
Likewise, the locking structure between the second adjusting member 310 and the rod member 121 may be a threaded structure, a fastening structure, a clasping structure, or the like, and for convenience of implementation, a threaded structure is preferably used.
Still further, a sleeve 420 is provided on the smoothing plate 400, and the rod 121 passes through the sleeve 420. Thereby, the smoothing plate 400 is enabled to realize sliding guide by the rod 121. Specifically, taking the example of providing the rod members 121 at both ends of the leveling plate 400, the transition frames 410 are provided at both ends of the leveling plate 400, respectively, and the shaft sleeves 420 are provided on the transition frames 410.
Still further, referring to fig. 1 and 3, in this embodiment, the diaphragm pressing plate mechanism further includes a guide assembly. The guide assembly is disposed parallel to the rod 121. The upper end of the rod 121 is connected with the movable part of the guide assembly. Thereby, it is possible to provide the movement guide in the vertical direction to the lower press plate 300, so that the lower press plate 300 moves more smoothly.
The diaphragm pressing plate mechanism further includes a first cylinder 600 and a second cylinder 700. An output shaft of the first cylinder 600 is connected to the upper platen 200 to drive the upper platen 200 up or down.

The working principle of the diaphragm pressing plate mechanism is as follows:
when the material is taken, the first air cylinder 600 and the second air cylinder 700 respectively drive the upper pressing plate 200 to ascend and the lower pressing plate 300 to descend, and meanwhile, the lower pressing plate 300 drives the smoothing plate 400 to ascend through the synchronous belt 520, so that a second interval is formed between the smoothing plate 400 and the lower pressing plate 300 in an unfolding mode, and the feeding manipulator penetrates through the diaphragm pressing plate mechanism to pick up the stacked battery cells.
When the membrane is pulled, the blanking manipulator moves the battery cell horizontally through the membrane pressing plate mechanism to pull the membrane out for a certain length; after the diaphragm is pulled out for a specified length, the diaphragm is cut in a hot melting mode, the cut diaphragm moves together with the battery cell, before the tail end of the diaphragm passes through the diaphragm pressing plate mechanism, the lower pressing plate 300 is driven by the second air cylinder 700 to ascend so as to drive the smoothing plate 400 to descend, a first interval of about 0.1 mm-1.0 mm is formed between the lower pressing plate 300 and the smoothing plate 400, and the tail end of the diaphragm is smoothed by the smoothing plate 400 when passing through the diaphragm pressing plate mechanism.
During winding, before the tail end of the diaphragm passes through the diaphragm pressing plate mechanism, the first cylinder 600 drives the upper pressing plate 200 to press down, the pacifying plate 400 is pressed onto the lower pressing plate 300, and then the tail end of the diaphragm is pressed, so that the winding mechanism at the winding position can smoothly wind the tail film.
Based on the above-mentioned diaphragm pressing plate mechanism, the embodiment of the invention also provides a lamination machine, which has all the beneficial effects of the above-mentioned diaphragm pressing plate mechanism, see above for details, and will not be repeated here.
