Based on the foregoing, the battery slice cutting apparatus in the prior art generally needs to provide a separate cooling spray head, but providing the cooling spray head separately and spraying the cooling liquid from the cooling spray head leads to an increase in manufacturing cost and production cost. In order to solve the above problems, the present embodiment provides a battery slice cutting apparatus, please refer to fig. 1 and fig. 2, the battery slice cutting apparatus includes a laser cutting mechanism 210 and a transferring mechanism 220, the laser cutting mechanism 210 is configured to cut a battery slice 100 located at a cutting station, the transferring mechanism 220 includes a transferring line body 221 and a carrying platform 222, the carrying platform 222 is slidably connected to the transferring line body 221 and can move to the cutting station along an extending direction of the transferring line body 221, the carrying platform 222 includes a carrying plate 2221, the carrying plate 2221 is a glass plate, the carrying plate 2221 is configured to simultaneously absorb portions of the battery slice 100 located at two sides of the cutting station 110, and laser emitted by the laser cutting mechanism 210 can penetrate through the glass plate.
In this embodiment, the bearing plate 2221 of the cell cutting device is a glass plate, laser with a specific wavelength is emitted by the laser cutting mechanism 210, the bearing plate 2221 has a higher light transmittance, that is, the glass plate has a good light transmittance, when laser emitted by the laser cutting mechanism 210 irradiates on the bearing plate 2221, the laser can penetrate through the glass plate, the bearing plate 2221 is not easy to damage, so that the bearing plate 2221 in this embodiment is not required to be provided with an avoiding groove, the cell 100 located at the bottom of the cutting groove is in direct contact with the bearing plate 2221, the heat of the cell 100 can be directly transmitted to the bearing plate 2221, thereby the heating region on the cell 100 is rapidly cooled, so that the cell 100 can be split along the cutting groove. Therefore, in this embodiment, the battery piece 100 can be cut without separately providing a cooling nozzle, so that the manufacturing cost of the battery piece cutting device and the production cost of the battery piece 100 cut by the battery piece cutting device are both low.
If the carrier 2221 only adsorbs the battery piece 100 located on one side of the cutting street 110, when the laser cutting mechanism 210 opens a cutting groove on the battery piece 100 along the cutting street 110 of the battery piece 100, the battery piece 100 located on the other side of the cutting street 110 may shake, which may cause irregular rupture of the battery piece 100, that is, the battery piece 100 does not split along the cutting groove, and thus the failure rate of the battery piece 100 obtained by cutting is high, whereas the carrier 2221 in this embodiment can simultaneously adsorb the parts of the battery piece 100 located on both sides of the cutting street 110, so as to ensure that when the laser cutting mechanism 210 opens a cutting groove on the battery piece 100 along the cutting street 110 of the battery piece 100, the parts of the battery piece 100 located on both sides of the cutting street 110 do not shake, that is, the battery piece 100 can be stably adsorbed on the carrier 2221, thereby ensuring that the battery piece 100 can accurately split along the cutting groove, thereby ensuring the qualification rate of the battery piece 100 obtained by cutting.
Referring to fig. 2, the carrier plate 2221 of the present embodiment is provided with two rows of absorption holes 22211, and when the battery piece 100 is carried on the carrier plate 2221, the two rows of absorption holes 22211 are respectively located at two sides of the cutting street 110 of the battery piece 100, so as to ensure that the carrier plate 2221 can simultaneously absorb portions of the battery piece 100 located at two sides of the cutting street 110.
Further, as shown in fig. 1, the laser cutting mechanism 210 includes a first laser emitting head 211 and a second laser emitting head 212 that are disposed at intervals along the extending direction of the transfer line body 221, where the first laser emitting head 211 is configured to open a cutting groove on the battery piece 100, and the second laser emitting head 212 is configured to heat a groove wall of the cutting groove on the battery piece 100. The structures of the first laser emitting head 211 and the second laser emitting head 212 are the prior art, and this embodiment will not be described in detail.
Specifically, in this embodiment, after the first laser emitter 211 forms the cutting groove on the battery piece 100 along the cutting street 110 of the battery piece 100, the second laser emitter 212 heats the groove wall of the cutting groove, and since the battery piece 100 at the bottom of the cutting groove directly contacts with the bearing plate 2221, after the groove wall of the cutting groove on the battery piece 100 is heated, a temperature difference is formed between the battery piece 100 and the bearing plate 2221, and the heat of the battery piece 100 can be rapidly transferred to the bearing plate 2221, so that the heating region on the battery piece 100 is rapidly cooled, a thermal stress is formed in the heating region of the battery piece 100, and the battery piece 100 can be further split along the cutting groove.
Since the heat of the battery cell 100 can be rapidly transferred to the carrier plate 2221 after the groove walls of the cut grooves on the battery cell 100 are heated, which can cause the temperature of the carrier plate 2221 to rapidly rise, in order to prevent the carrier plate 2221 from being broken due to thermal stress, the carrier plate 2221 in this embodiment is preferably a high borosilicate glass plate, which has a very low thermal expansion coefficient, and thus has a stronger fracture resistance.
It can be understood that, when the battery piece 100 is supported on the supporting plate 2221, the two rows of the absorption holes 22211 have the same distance with the cutting streets 110 of the battery piece 100, so as to further ensure that the battery piece 100 can be stably absorbed on the supporting plate 2221.
Further, when the battery piece 100 is carried on the carrying plate 2221, the suction forces formed in all the suction holes 22211 on the carrying plate 2221 are equal, so that the suction forces formed in all the suction holes 22211 in any row of the suction holes 22211 are equal, so as to ensure that the suction forces applied to the portions of the battery piece 100 located on either side of the cutting street 110 at each position along the extending direction of the cutting street 110 are the same, and simultaneously, the suction force formed in one row of the two rows of the suction holes 22211 is equal to the suction force formed in the other row of the two rows of the suction holes 22211, so as to ensure that the suction forces applied to the portions of the battery piece 100 located on both sides of the cutting street 110 are the same, thereby further ensuring that the battery piece 100 can be stably adsorbed on the carrying plate 2221.
In this embodiment, all the absorption holes 22211 of the supporting plate 2221 are connected to the same vacuum generator (not shown in the figure), when the battery sheet 100 is supported on the supporting plate 2221, the vacuum generator simultaneously forms negative pressure in all the absorption holes 22211 of the supporting plate 2221 to generate suction force to the battery sheet 100, and the suction forces formed in all the absorption holes 22211 of the supporting plate 2221 are equal.
In the present embodiment, the distance between any two adjacent suction holes 22211 in each row of suction holes 22211 is equal, so as to ensure that the suction force applied to the portions of the battery pieces 100 located on either side of the cutting street 110 is uniformly distributed along the extending direction of the cutting street 110, thereby further ensuring that the battery pieces 100 can be stably sucked on the bearing plate 2221.
As shown in fig. 1 to fig. 3, in order to slidably connect the carrying platform 222 to the transfer line body 221, the carrying platform 222 in this embodiment further includes a connecting plate 2222 and a mounting plate 2223, the connecting plate 2222 is slidably connected to one side of the transfer line body 221, the carrying plate 2221 is fixedly connected to the mounting plate 2223, the mounting plate 2223 is fixedly connected to the connecting plate 2222, the mounting plate 2223 is provided with two strip-shaped holes 22231, two rows of adsorption holes 22211 on the carrying plate 2221 are respectively opposite to the two strip-shaped holes 22231, and the two strip-shaped holes 22231 are communicated with the same vacuum generator.
Because the bearing plate 2221 is fixedly connected to the mounting plate 2223, the mounting plate 2223 is fixedly connected to the connecting plate 2222, and the mounting plate 2223 and the connecting plate 2222 are both aluminum plates, heat on the bearing plate 2221 in this embodiment can be rapidly transferred to the mounting plate 2223 and the connecting plate 2222, that is, the temperature of the bearing plate 2221 can be rapidly lowered after being raised, so as to ensure that after the groove wall of the cutting groove on the next cell piece 100 is heated, a temperature difference can be formed between the bearing plate 2221 and the next cell piece 100, and further ensure that heat on the next cell piece 100 can be rapidly transferred to the bearing plate 2221 when the cell piece cutting device cuts the next cell piece 100.
It can be understood that, because the battery piece cutting device in the prior art needs to adopt the cooling spray head to spray the cooling liquid to cool the heating area of the battery piece, when the battery piece cutting device in the prior art is used to cut the battery piece, a special worker needs to regularly clean the residual cooling liquid on the bearing plate, which leads to further improvement of the production cost, and when the worker cleans the bearing plate, the battery piece cutting device needs to be in the standby state for a long time, which leads to reduction of the production efficiency.
Referring to fig. 1, the transferring mechanism 220 in the embodiment includes two carrying platforms 222, and the two carrying platforms 222 can be alternately moved to the cutting station to prevent the laser cutting mechanism 210 from being in a standby state for a long time, so as to further improve the production efficiency of the battery slice cutting device.
Referring to fig. 1, in the embodiment, the two carrying platforms 222 are respectively connected to two sides of the transfer line body 221 in a sliding manner, and the mounting plate 2223 of one of the two carrying platforms 222 is located above the carrying plate 2221 of the other of the two carrying platforms 222, so as to prevent the two carrying platforms 222 from interfering during the moving process.
It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Numerous obvious variations, adaptations, and substitutions will occur to those skilled in the art without departing from the scope of the present invention. This need not be, nor should it be exhaustive of all embodiments.
