In the prior art, after the battery piece is wrapped, the battery piece needs to be transferred, but when the existing buffer storage flower basket is used for transferring the battery piece, the battery piece is easy to displace, so that the rubber coating parts on the peripheral edges of the battery piece are polluted or collided, the wrapping effect is influenced, and the battery piece is caused to lose efficacy, leak electricity and the like.

The inventor finds that in the transferring process of the battery piece, the vacuum adsorption principle is adopted to prevent the battery electricity from displacing, and the encapsulation parts at the peripheral edges of the battery piece can be effectively prevented from being polluted or colliding, so that the edge covering effect is ensured, and the problems of failure, electric leakage and the like of the battery piece are solved.

In a first aspect, please refer to fig. 1, an embodiment of the present application provides a cell slice caching flower basket 10, wherein a cavity 111 is disposed in a substrate 100, and the substrate 100 is provided with an air pumping hole 120 communicated with the cavity 111; the inner wall of the base body 100 is convexly provided with a supporting piece 130 for supporting the battery piece, a first channel 131 communicated with the cavity 111 is arranged in the supporting piece 130, the first channel 131 is provided with an opening 1311, and the opening 1311 is positioned at one end of the top of the supporting piece 130 far away from the inner wall of the base body 100.

In the application, the supporting piece 130 is used for supporting the battery piece, the arranged cavity 111, the air suction opening 120 and the first channel 131 jointly form an air flow channel, and negative pressure can be formed on the end face of the battery piece supported by the supporting piece 130 through the air flow channel, so that the battery piece can be firmly adsorbed by the battery piece caching basket 10 in the battery piece transferring process, the battery piece is prevented from being displaced, the edge covering effect is ensured, and the problems of failure, electric leakage and the like of the battery piece are solved; in addition, the openings 1311 of the first channel 131 are disposed at one end of the top of the support 130 away from the inner wall of the base 100, so that the distribution range of the openings 1311 is small and concentrated at a position contacting with the battery cell, thereby improving adsorption efficiency and securing adsorption effect.

It will be appreciated that the cell sheet caching flower basket 10 may be used in conjunction with automated equipment that may be constructed as is known in the art, in view of the intelligent mechanization of the cell sheet production line.

For further understanding of the technical solution, the operation principle of the battery piece buffer storage flower basket 10 is explained here.

In the battery piece feeding stage, after the wrapping is completed, the battery piece is placed on the supporting piece 130 in the battery piece caching flower basket 10 through the automatic device, meanwhile, the operation of vacuumizing the battery piece caching flower basket 10 is completed, so that the end face, contacted with the battery piece, of the supporting piece 130 generates negative pressure, the generated negative pressure can firmly adsorb and fix the battery piece, after the transfer process is completed, the automatic device is used for performing airflow backfill operation on the battery piece caching flower basket 10 again, and after the battery piece is loosened, the battery piece is transferred to the next process.

It is to be understood that the number of the supporting members 130 is not particularly limited and may be set as required as is well known in the art.

It should be noted that the form of the support member 130 may be adjusted in consideration of the quality of the hemming.

Referring to fig. 2, as an example, the supporting member 130 includes a horizontal section 132 and a supporting section 133 connected to each other, the first channel 131 is distributed in the horizontal section 132 and the supporting section 133, one end of the horizontal section 132 is connected to the inner wall of the base 100, one end of the supporting section 133 away from the horizontal section 132 extends toward the top of the base 100, and the opening 1311 is located at an end surface of the supporting section 133 away from the horizontal section 132.

In this embodiment, the supporting member 130 is provided in a segmented form, and the horizontal segment 132 is connected between the inner wall of the base 100 and the supporting segment 133, so that when the battery piece is adsorbed and fixed on the supporting segment 133, the distance between the two sides of the battery piece and the inner wall of the base 100 is relatively long, the contact between the two side edges of the battery piece and the inner wall of the base 100 can be avoided, and the edge covering effect can be ensured. In addition, the end of the support section 133 far from the horizontal section 132 extends towards the top of the base 100, and the opening 1311 is located at the end face of the end of the support section 133 far from the horizontal section 132, so that a certain height difference exists between the horizontal section 132 and the support section 133 of the support member 130, when the battery piece is adsorbed and fixed, the peripheral edge of the battery piece is in a suspended state, excessive contact between the peripheral edge of the battery piece and the upper surface of the support member 130 is avoided, and the edge covering effect is further ensured.

It is to be understood that the size of the horizontal segment 132 in the axial direction and the size of the support segment 133 in the axial direction are not particularly limited, and the size of the horizontal segment 132 in the axial direction may be larger than the size of the support segment 133 in the axial direction, may be the same as the size of the support segment 133 in the axial direction, and may be smaller than the size of the support segment 133 in the axial direction.

As an example, the horizontal section 132 has a larger dimension in the axial direction than the support section 133.

In this embodiment, when the battery piece is fixed by adsorption, the distance between the two sides of the battery piece and the inner wall of the base 100 in the axial direction of the horizontal section 132 is further increased, which is more beneficial to ensuring the edge covering quality.

On this basis, the angle relationship at the connection position of the horizontal segment 132 and the supporting segment 133 is not particularly limited, and it can be understood that the horizontal segment 132 and the supporting segment 133 of the supporting member 130 have a certain height difference, so that the peripheral edge of the battery piece is in a suspended state when the battery piece is adsorbed and fixed.

It should be noted that the angle at the junction of the horizontal segment 132 and the support segment 133 can be optimized to better suspend the peripheral edge of the cell.

As an example, the horizontal segment 132 and the supporting segment 133 are perpendicular, that is, the angle at the joint of the horizontal segment 132 and the supporting segment 133 is 90 °, and the spatial configuration of the supporting member 130 is L-shaped.

In this embodiment, the horizontal section 132 and the support section 133 are perpendicular, on one hand, when the axial length of the support section 133 is fixed, the distance from the end face of one end of the support section 133 away from the horizontal section 132 to the top of the horizontal section 132 is larger, so that when the battery piece is adsorbed at the opening 1131, the distance from the bottom of the battery piece to the top of the horizontal section 132 is larger, which is more favorable for suspending the peripheral edge of the battery piece; on the other hand, the vertical connection enables the axial direction of the supporting section 133 to be vertically distributed, which is beneficial to enhancing the structural stability of the supporting member 130

The inventors have also studied that the arrangement of the support segments 133 can be optimized in order to ensure the quality of the battery piece.

As an example, an end surface of the supporting segment 133 away from the horizontal segment 132 is provided with a cushion 134, and the cushion 134 is disposed outside the opening 1311.

In this embodiment, the cushion pad 134 is provided to reduce the impact between the bottom of the battery piece and the end surface of the support segment 133 when the battery piece is fixed by suction, thereby preventing the battery piece from being damaged.

It is understood that the sectional shape of the cushion pad 134 in the thickness direction of the battery cell is not particularly limited, and may be any one of a triangle, a square, a rectangle, a circle, and an ellipse having the opening 1311 provided therein.

On this basis, the material of the cushion pad 134 is not particularly limited, and may be selected from conventional cushion materials.

It should be noted that the shape and structure of the base 100 are not particularly limited, and the distribution of the supporting members 130 is not particularly limited, and it should be understood that the base can support the battery cells stably.

As an example, the base 100 includes two baffles 110 oppositely disposed, and each baffle 110 has a cavity 111 therein; the support 130 is connected to the inner wall of the baffle 110, and the first channel 131 in the support 130 communicates with the corresponding cavity 111 in the baffle 110.

In this embodiment, the base 100 is disposed as two opposite baffles 110, and the support 130 is disposed on the inner wall of the baffles 110, which is convenient for taking and placing the battery cells. In addition, the first channel 131 in the support 130 communicates with the cavity 111 in the corresponding barrier 110, so that the connection of the first channel 131 and the cavity 111 is facilitated.

On the basis, in order to further increase the convenience of taking and placing the battery pieces, the distance between the two baffles 110 can be adjusted.

As an example, the distance between the two baffles 110 corresponds to the long side of the cell, and the distance is slightly larger than the size of the long side of the cell; the support 130 on each baffle 110 corresponds to the short side of the cell.

It should be noted that the structure of the baffle 110 may be adjusted in consideration of the stability of the substrate 100 and the convenience of the air-extracting operation.

As an example, a connecting member 200 is disposed between the two baffles 110, a second channel 210 is disposed in the connecting member 200, and the second channel 210 is communicated with the cavity 111 in each baffle 110.

In this embodiment, the connecting member 200 is provided to connect two baffles 110 together, so as to improve the stability of the base 100; the second channel 210 is used for communicating the cavities 111 in the two baffles 110 together, so that the cavities in the two baffles 110 can be conveniently and synchronously exhausted at one position.

It is understood that the number of the connecting members 200 is not particularly limited, and the number may be 1, two, or three.

As an example, the number of the connection members 200 is two.

On this basis, the specific position of the connecting member 200 is not limited, and the connecting member may be disposed on the top of the two baffles 110 at the same time, may be disposed on the bottom of the two baffles 110 at the same time, and may be disposed on each of the top and the bottom of the two baffles 110.

As an example, one connector 200 is provided at each of the top and bottom of the two baffles 110.

In this embodiment, the top and bottom of the barrier 110 are each provided with a connector 200, which can further increase the stability of the barrier 110.

It should be noted that the form of the connection member 200 may be optimized in consideration of the efficiency of vacuum suction.

As an example, the second channel 210 is not provided in the connector 200 located at the top of the baffle 110, and the second channel 210 is provided only in the connector 200 located at the bottom of the baffle 110.

In this embodiment, the second channel 210 is provided only in the bottom connection member 200, which is advantageous for rapidly completing the vacuum process, thereby improving the efficiency of the vacuum adsorption process.

It will be appreciated that structural adjustments may be made to the overall airflow path in view of control of the overall airflow path and consistency of air pressure changes.

As an example, the suction port 120 is located on the connection member 200 and communicates with the second passage 210.

In this embodiment, the air suction ports 120 are disposed on the connection member 200 because the cavities 111 and the first passages 131 on both sides are integrally disposed in a relatively distributed positional relationship with respect to the connection member 200, and this arrangement can ensure that the air pressures in the cavities 111 and the first passages 131 at both ends of the connection member 200 are uniformly changed.

It should be noted that when the pumping port 120 is not provided in the connection member 200, the pumping port 120 may be provided in one of the baffles 110 and communicated with the first passages 131, or may be provided in two of the baffles 110 and communicated with the two first passages 131, respectively.

As an example, referring to fig. 3, the pumping holes 120 are provided on the two baffles 110 and respectively communicate with the two first passages 131.

In this embodiment, each of the baffles 110 is provided with one pumping hole 120, which can improve the efficiency of the vacuum pumping.

It should be noted that the manner of providing one pumping hole 120 on each baffle 110 is also applicable to the case of not providing the connector 200.

It is understood that the number of the pumping holes 120 on each connecting member 200 or each baffle 110 is not limited, and may be one, two, or three.

As an example, the number of the pumping ports 120 is 1.

It should be noted that, since the number of the first channels 131 is greater than that of the cavities 111, in order to ensure that the cell buffering flower basket 10 can quickly absorb or release the cells, thereby improving the transfer efficiency of the cells, the sizes of the single cavities 111 and the single first channels 131 may be adjusted.

As an example, the cross-sectional area of the single cavity 111 ≧ the cross-sectional area of the single first passage 131.

The inventor further researches and discovers that the air extraction opening 120 can be adjusted to improve the overall controllability of the cell piece buffer storage flower basket 10.

Referring to fig. 4, as an example, the air extracting opening 120 is provided with an air flow valve 121, and the air flow valve 121 is used for controlling the opening and closing of the air extracting opening 120.

In this embodiment, the air flow valve 121 is arranged at the air extraction opening 120, so that on one hand, when the battery piece is in vacuum adsorption by the battery piece cache basket 10, the air flow valve 121 is closed, so that the battery piece cache basket 10 is always kept in a vacuum adsorption state in the battery piece transfer process, and the battery piece is prevented from displacing; on the other hand, after the battery piece is transferred, the airflow valve 121 is opened to realize airflow backfilling, so that the battery piece is loosened by the battery piece buffer basket 10, and battery piece blanking is completed. Based on this, the controllability of the entire cell buffer basket 10 is improved by the control of the airflow valve 121.
