[0065] The technical solution of the present disclosure will be described in detail below with reference to specific embodiments and drawings.

[0066] Example 1

[0067] The present disclosure provides a guide device, as shown in Figures 1 to 4, for guiding battery cells into a battery housing 200. The guide device 10 includes a fixed guide member 1, at least one movable guide member 2, and a guide drive assembly 3. The guide drive assembly 3 is in transmission connection with the movable guide member 2, and the guide drive assembly 3 is used to drive the movable guide member 2 to move between at least a first state and a second state. When the movable guide member 2 is in the first state, the movable guide member 2 and the fixed guide member 1 are arranged to form a first guide channel 4. When the movable guide member 2 is in the second state, the movable guide member 2 and the fixed guide member 1 are arranged to form a second guide channel 5. The width and / or height of the cross section of the second guide channel 5 are different from those of the first guide channel 4. The inlet ends of the first guide channel 4 and the second guide channel 5 are formed with guide portions to guide the battery cells into the battery housing 200.

[0068] It should be explained that the inlet ends of the first guide channel 4 and the second guide channel 5 refer to the ends of the first guide channel 4 and the second guide channel 5 facing the battery cell, which are the first ports that the battery cell passes through when being introduced into the battery housing 200 .

[0069] In the above, the guide drive assembly 3 is used to drive the movable guide member 2 to move at least between the first state and the second state, so that the movable guide member 2 and the fixed guide member 1 can be surrounded to form a first guide channel 4 or a second guide channel 5. The entrance ends of the first guide channel 4 and the second guide channel 5 are formed with a guide portion. When guiding the battery cell into the battery housing 200, the guide portion can be located at the front end of the entrance end of the battery housing 200 to guide the battery cell to be loaded into the battery housing 200, so that the battery cell can be loaded into the battery housing 200 more smoothly through the guide device 10. Moreover, the width and / or height of the cross section of the first guide channel 4 and the second guide channel 5 are different, so that the first guide channel 4 and the second guide channel 5 can be adapted to two battery shells 200 of different sizes. Compared with a guide device 10 that can only be adapted to one size of battery shell 200, the battery shell insertion device 100 assembled with the guide device 10 needs to replace the corresponding guide device 10 when introducing battery cells into battery shells 200 of different sizes, which is cumbersome and laborious, resulting in the battery shell insertion device 100 being unable to meet the rapid response to the production needs of batteries of different sizes, thereby reducing the production efficiency of batteries of different sizes. The guide device 10 disclosed in the present invention can effectively reduce the number of replacements for battery shells 200 of different sizes, thereby improving the production efficiency of batteries of different sizes.

[0070] In addition, the guide drive assembly 3 is used to drive the movable guide member 2 to move at least between the first state and the second state, that is, the movable guide member 2 can be in the first state, the second state, or the third state under the drive of the guide drive assembly 3, so that the movable guide member 2 and the fixed guide member 1 can form a first guide channel 4, a second channel, or a third channel, which is not limited here, so that the guide device 10 can adapt to more battery shells 200 of different sizes and models, so that more batteries of different sizes and models can be put into the shell, further improving the production efficiency of the battery shelling equipment 100 assembled with the guide device 10 for batteries of different sizes and models.

[0071] When the battery cell is introduced into the battery housing 200 through the above-mentioned guiding device 10, first, the battery housing 200 can be placed in the first guide channel 4 or the second guide channel 5 of the guiding device 10, such as, the inlet end of the battery housing 200 and the part close to the inlet end are placed in the first guide channel 4 or the second guide channel 5 of the guiding device 10. At this time, the battery housing 200 can be fixed by the guiding device 10 to prevent the battery cell from moving along the introduction direction during the process of introducing the battery cell into the battery housing; then, the battery cell is placed at the inlet end of the first guide channel 4 or the second guide channel 5, and the central axis of the battery cell extending along the introduction direction is adjusted to be aligned with the central axis of the battery housing 200 extending along the introduction direction and the central axis of the first guide channel 4 or the second guide channel 5 extending along the introduction direction; then, the battery cell is pushed into the battery housing 200 along the first guide channel 4 or the second guide channel 5 until the battery cell is completely loaded.

[0072] Among them, when the movable guide member 2 is in the first state, the movable guide member 2 and the fixed guide member 1 are arranged to form a first guide channel 4. The first guide channel 4 can be formed by all the movable guide members 2 and the fixed guide member 1, or by part of the movable guide members 2 and the fixed guide member 1. This is not limited here. Similarly, when the movable guide member 2 is in the second state, the movable guide member 2 and the fixed guide member 1 are arranged to form a second guide channel 5. The second guide channel 5 can be formed by all the movable guide members 2 and the fixed guide member 1, or by part of the movable guide members 2 and the fixed guide member 1. This is not limited here.

[0073] Furthermore, the movable guide member 2 and the fixed guide member 1 enclose a first guide channel 4 or a second guide channel 5. The movable guide member 2 may abut against the fixed guide member 1, or a gap may be provided between the movable guide member 2 and the fixed guide member 1, and this is not limited here. For example, when there is only one movable guide member 2, the movable guide member 2 and the fixed guide member 1 may abut against each other to form the first guide channel 4, or the movable guide member 2 and the fixed guide member 1 may have a gap provided between them, and the two may enclose a second guide channel 5.

[0074] In addition, the number of movable guide members 2 can be one, two or more, which is not limited here.

[0075] The inlet ends of the first guide channel 4 and the second guide channel 5 are formed with guide portions, which may be guide slopes or guide arc surfaces, and are not limited here.

[0076] Optionally, as shown in Figures 3 to 6, the movable guide member 2 includes a first movable guide member 21, which is arranged opposite to the fixed guide member 1, and the guide drive assembly 3 is used to drive the first movable guide member 21 to move toward or away from the fixed guide member 1, so that the first movable guide member 21 moves at least between the first state and the second state; and when the first movable guide member 21 is in the first state or the second state, the first movable guide member 21 and the fixed guide member 1 are arranged to form a first guide channel 4 or a second guide channel 5.

[0077] Therefore, by driving the first movable guide member 21 to move toward or away from the fixed guide member 1 through the guide drive component 3, the first movable guide member 21 and the fixed guide member 1 can be surrounded to form a first guide channel 4 or a second guide channel 5, so that the structure of the guide device 10 is simple and easy to implement, and the operation of changing the guide channel can be relatively simple.

[0078] Among them, the first movable guide member 21 is arranged opposite to the fixed guide member 1, and when the cross-sectional shape of the guide channel formed by the first movable guide member 21 and the fixed guide member 1 is rectangular, when the first movable guide member 21 moves at least between the first state and the second state through the guide drive assembly 3, the guide channel formed by the first movable guide member 21 and the fixed guide member 1 may have a change in the width of the cross section, or a change in the height of the cross section, that is, the guide device 10 can be compatible with a variety of battery shells 200 with the same width and different thicknesses, such as the guide devices 10 shown in Figures 3 and 4, or the guide device 10 can be compatible with a variety of battery shells 200 with different widths and the same thickness, such as the guide devices 10 shown in Figures 5 and 6.

[0079] Optionally, as shown in Figures 7 to 10, the movable guide 2 also includes a second movable guide 22 and a third movable guide 23, and the second movable guide 22 and the third movable guide 23 are respectively located on opposite sides of the fixed guide 1 along the first direction, and the guide drive assembly 3 is used to drive the second movable guide 22 and the third movable guide 23 to move along the first direction (the direction shown by x in Figure 7), respectively. The first direction is configured to be perpendicular to the loading direction of the battery cell and perpendicular to the moving direction of the first movable guide 21 relative to the fixed guide 1; when the first movable guide 21, the second movable guide 22 and the third movable guide 23 are all in the first state, the first movable guide 21 and the fixed guide 1 are surrounded by a first guide channel 4, and when the first movable guide 21, the second movable guide 22 and the third movable guide 23 are all in the second state, the first movable guide 21, the second movable guide 22, the third movable guide 23 and the fixed guide 1 are surrounded by a second guide channel 5.

[0080] In this way, the width or thickness of the cross-section of the guide channel formed by the movable guide member 2 and the fixed guide member 1 can be varied within a larger range of sizes, so that the guide channel can be compatible with battery shells 200 of more sizes and types, thereby further improving the production efficiency of the battery shell insertion equipment 100 assembled with the guide device 10 for batteries of different sizes and types.

[0081] Exemplarily, when the fixed guide member 1 is placed horizontally and the first movable guide member 21 is located above the fixed guide member 1, the first direction may be the horizontal direction, and the second movable guide member 22 and the third movable guide member 23 may be respectively located on both sides of the fixed guide member 1 along the horizontal direction, so that when the first movable guide member 21, the second movable guide member 22 and the third movable guide member 23 are all in the first state, as shown in Figure 7, the first movable guide member 21 and the fixed guide member 1 may be surrounded to form a first guide channel 4, so that when the first movable guide member 21, the second movable guide member 22 and the third movable guide member 23 are all in the second state, as shown in Figure 8, the second movable guide member 22 and the third movable guide member 23 are located between the first movable guide member 21 and the fixed guide member 1, and the first movable guide member 21, the second movable guide member 22, the third movable guide member 23 and the fixed guide member 1 are surrounded to form a second guide channel 5.

[0082] The second movable guide 22 or the third movable guide 23 can be any one of a guide block, a guide plate, etc., which is not limited here. In addition, the structure of the second movable guide 22 can be substantially the same as that of the third movable guide 23, reducing the structural complexity of the guide device 10.

[0083] Optionally, as shown in Figures 11 and 12, the fixed guide member 1 has a first inner wall 11, and the first movable guide member 21 has a second inner wall 211 opposite to and parallel to the first inner wall 11; the first movable guide member 21 also has a third inner wall 212 and a fourth inner wall 213, and the third inner wall 212 and the fourth inner wall 213 are both perpendicular to the second inner wall 211, and are respectively arranged on the two sides opposite to each other along the first direction of the second inner wall 211, and / or, the fixed guide member 1 also has a fifth inner wall 12 and a sixth inner wall 13, and the fifth inner wall 12 and the sixth inner wall 13 are both perpendicular to the first inner wall 11, and are respectively arranged on the two sides opposite to each other along the first direction of the first inner wall 11, and the first direction is configured to be perpendicular to the loading direction of the battery cell and parallel to the first inner wall 11.

[0084] In this way, the cross-section of the guide space formed by the fixed guide member 1 and the movable guide member 2 can be changed in the direction perpendicular to the first inner wall 11, that is, the height dimension of the cross-section of the guide space can be changed. For example, the width of the cross-section of the first guide space and the second guide space is the same, but the height is different, so that the guide space can be compatible with a variety of battery shells 200 with the same width and different thicknesses, and the number of movable guide members 2 can be reduced, thereby reducing the difficulty of manufacturing the guide device 10.

[0085] In addition, when the movable guide member 2 also includes a second movable guide member 22 and a third movable guide member 23, the inner wall of the second movable guide member 22 may be parallel to the third inner wall 212 and / or the fifth inner wall 12, and the inner wall of the third movable guide member 23 may be parallel to the fourth inner wall 213 and / or the sixth inner wall 13. At this time, the first movable guide member 21, the second movable guide member 22, the third movable guide member 23 and the fixed guide member 1 may be jointly arranged to form a guide channel. Of course, it is also possible that the first movable guide member 21 and the fixed guide member 1 are arranged to form a guide channel.

[0086] The above-mentioned guide drive assembly 3 is used to drive the first movable guide member 21, the second movable guide member 22 and the third movable guide member 23 to move along the first direction respectively. In some embodiments, the guide drive assembly 3 may include a driving member, and the driving member can drive the first movable guide member 21, the second movable guide member 22 and the third movable guide member 23 respectively through multiple clutches, thereby reducing the number of driving members and reducing costs.

[0087] In other embodiments where the guide drive assembly 3 is used to respectively drive the first movable guide 21, the second movable guide 22 and the third movable guide 23 to move along the first direction, the guide drive assembly 3 includes a first guide drive, a second guide drive and a third guide drive, the first guide drive is transmission-connected to the first movable guide 21, the second guide drive is transmission-connected to the second movable guide 22, and the third guide drive is transmission-connected to the third movable guide 23.

[0088] In this way, the first movable guide member 21, the second movable guide member 22 and the third movable guide member 23 can be moved separately and independently, which simplifies the driving process of the three by the guide drive component 3, making the driving operation of the first movable guide member 21, the second movable guide member 22 and the third movable guide member 23 by the guide drive component 3 simple and quick; at the same time, the first movable guide member 21, the second movable guide member 22 and the third movable guide member 23 can also be moved at the same time, thereby improving efficiency.

[0089] The first guide drive member can be any one of a pneumatic cylinder, an electric cylinder, a combination of a motor and a lead screw nut, etc., and is not limited here. The second guide drive member and the third guide drive member can have substantially the same structure as the first guide drive member, and will not be described in detail here.

[0090] In addition, the first guide driving member is connected to the first movable guide member 21 in a transmission manner. The driving end of the first guide driving member can be directly connected to the first movable guide member 21, or the driving end of the first guide driving member can be connected to the first movable guide member 21 through a flange, a connecting plate, a connecting seat, etc., which is not limited here.

[0091] In other embodiments, as shown in Figures 13 to 15, the second movable guide 22 includes a first sub-movable guide 22a and a second sub-movable guide 22b, and the third movable guide 23 includes a third sub-movable guide 23a and a fourth sub-movable guide 23b. The first sub-movable guide 22a and the third sub-movable guide 23a are arranged close to the first movable guide 21, and the second sub-movable guide 22b and the fourth sub-movable guide 23b are arranged close to the fixed guide 1; the first sub-movable guide 22a has a plurality of first guide walls 221 and a plurality of second guide walls 222, and the plurality of first guide walls 221 and the plurality of second guide walls 222 are perpendicular to each other, the second sub-movable guide 22b has a third guide wall 223, and the third sub-movable guide 23a has a plurality of fourth guide walls 231 and a plurality of fifth guide walls 232, and the plurality of fourth guide walls 231 and the plurality of fifth guide walls 232 are mutually perpendicular. Vertically, the fourth sub-movable guide 23b has a sixth guide wall 233, multiple first guide walls 221 and multiple fourth guide walls 231 are parallel to the first direction, multiple second guide walls 222, third guide walls 223, multiple fifth guide walls 232 and sixth guide walls 233 are all perpendicular to the first direction; the guide drive assembly 3 can respectively drive the second sub-movable guide 22b and the fourth sub-movable guide 23b to move along the first direction, so that the third guide wall 223 is respectively aligned with the multiple second guide walls 222, and the sixth guide wall 233 is respectively flush with the multiple fifth guide walls 232, and the guide drive assembly 3 can drive the first movable guide 21 to move in a direction close to or away from the fixed guide 1, so that the inner wall of the first movable guide 21 is respectively aligned with the multiple first guide walls 221, or so that the inner wall of the first movable guide 21 is respectively flush with the multiple fourth guide walls 231.

[0092] Thus, the guide channel formed by the movable guide member 2 and the fixed guide member 1 can be compatible with a variety of battery shells 200 with the same width and different thicknesses, and can also be compatible with a variety of battery shells 200 with different widths and the same thicknesses, and can also be compatible with a variety of battery shells 200 with different widths and thicknesses. This means that the guide device 10 can adapt to more battery shells 200 of different sizes and models, so that the battery shell insertion equipment 100 assembled with the guide device 10 can perform battery cell shell insertion operations on more batteries of different sizes and models, further improving the production efficiency of the battery shell insertion equipment 100 assembled with the guide device 10 for batteries of different sizes and models.

[0093] The number of first guide walls 221 may be two, three, or more, and is not limited thereto. The number of second guide walls 222 may be two, three, or more, and is not limited thereto. The number of fourth guide walls 231 may be two, three, or more, and is not limited thereto. The number of fifth guide walls 232 may be two, three, or more, and is not limited thereto.

[0094] In addition, the guide drive assembly 3 can respectively drive the second sub-movable guide member 22b and the fourth sub-movable guide member 23b to move along the first direction. The guide drive assembly 3 can include one drive member, which is respectively connected to the second sub-movable guide member 22b and the fourth sub-movable guide member 23b. Alternatively, the guide drive assembly 3 can include two drives, which are respectively connected to the second sub-movable guide member 22b and the fourth sub-movable guide member 23b. Similarly, the first sub-movable guide member 22a and the third sub-movable guide member 23a can be driven by the same drive member, or can be driven separately by corresponding drives, which is not limited here.

[0095] Optionally, as shown in Figures 14 and 15, the inner wall of the fixed guide member 1 and the inner wall of the first movable guide member 21 are both planar and parallel to each other, the second sub-movable guide member 22b also has a seventh guide wall 224, and the fourth sub-movable guide member 23b also has an eighth guide wall 234, and the seventh guide wall 224 and the eighth guide wall 234 are both flush with the inner wall of the fixed guide member 1.

[0096] Thus, the seventh guide wall 224 and the eighth guide wall 234 can be flush with the inner wall of the fixed guide member 1, so that the size of the guide space formed by the movable guide member 2 and the fixed guide member 1 along the first direction can be larger, so that the guide space can be compatible with a battery shell 200 with a wider width, and the seventh guide wall 224 and the eighth guide wall 234 can also limit the outer wall of the battery shell 200, so that the battery shell 200 located in the guide space can be more stable.

[0097] The seventh guide wall 224 may be a plane flush with the inner wall of the fixed guide member 1 , and the eighth guide wall 234 may also be a plane flush with the inner wall of the fixed guide member 1 .

[0098] In some embodiments, the battery housing 200 is a square housing having a large surface, which is configured as the side surface with the largest area of ​​the battery housing 200 , and the inner wall of the fixed guide 1 that contacts the large surface of the battery housing 200 is arranged in a horizontal direction.

[0099] Thus, the fixed guide member 1 can be arranged in the horizontal direction, which facilitates the fixation of the fixed guide member 1. At the same time, when the battery housing 200 is placed in the guide channel formed by the fixed guide member 1 and the movable guide member 2, the large surface of the battery housing 200 can also move horizontally along the inner wall of the fixed guide member 1, so that the movement of the battery housing 200 can be relatively smooth.

[0100] In other embodiments, the ends of the first guide channel 4 and the second guide channel 5 away from the inlet end are used to engage with the outer wall of the open end of the battery housing 200 .

[0101] It should be explained that the ends of the first guide channel 4 and the second guide channel 5 away from the inlet end may be the portions of the first guide channel 4 and the second guide channel 5 that abut against the outer wall of the battery housing 200 .

[0102] Thus, when the battery cell is loaded into the battery housing 200 through the first guide channel 4 or the second guide channel 5 , the battery housing 200 can be prevented from moving due to thrust, thereby allowing the battery cell to be smoothly introduced into the battery housing 200 .

[0103] Example 2

[0104] The present disclosure also discloses a battery shell insertion device 100, as shown in Figure 16, comprising the guide device 10, the shell positioning device 20, and the battery cell positioning device 30 of any one of the first embodiments. The shell positioning device 20 is used to align the battery shell 200 with the end of the first guide channel 4 or the second guide channel 5 away from the inlet end; the battery cell positioning device 30 is used to align the battery cell with the inlet end of the first guide channel 4 or the second guide channel 5.

[0105] It should be explained that the above-mentioned alignment of the battery shell 200 with the end of the first guide channel 4 or the second guide channel 5 away from the inlet end means that the central axis of the battery shell 200 extending along the introduction direction of the battery cell is on the same straight line as the central axis of the first guide channel 4 extending along the introduction direction or the central axis of the second guide channel 5 extending along the introduction direction.

[0106] It also needs to be explained that the above-mentioned alignment of the battery cell with the inlet end of the first guide channel 4 or the second guide channel 5 means that the central axis of the battery cell extending along the introduction direction is on the same straight line as the central axis of the first guide channel 4 extending along the introduction direction or the central axis of the second guide channel 5 extending along the introduction direction.

[0107] In this embodiment, the shell positioning device 20 is used to align the battery shell 200 with the end of the first guide channel 4 or the second guide channel 5 away from the inlet end, and the battery cell positioning device 30 is used to align the battery cell with the inlet end of the first guide channel 4 or the second guide channel 5, so that the central axis of the battery shell 200 extending along the introduction direction and the central axis of the battery cell extending along the introduction direction are aligned with the central axis of the first guide channel 4 or the second guide channel 5 extending along the introduction direction, so that the battery cell can be smoothly loaded into the battery shell 200 through the first guide channel 4 or the second guide channel 5, effectively improving the efficiency of introducing the battery cell into the battery shell 200.

[0108] In addition, the guiding device 10 in the battery shell insertion device 100 is the guiding device 10 described in any one of the above embodiments. Therefore, the guiding device 10 of the battery shell insertion device 100 has substantially the same technical effect as the guiding device 10 in the above embodiment 1. Since the above embodiment 1 has described the guiding device 10 in more detail, it will not be repeated here.

[0109] The battery cells may be introduced into the battery housing 200 by manually pushing the battery cells into the battery housing 200 or by mechanically pushing the battery cells into the battery housing 200, which is not limited here.

[0110] Optionally, when the battery cell is pushed by a mechanical structure, as shown in Figures 16 and 17, the battery shell insertion device 100 also includes a pushing device 40, which is located on the side of the battery cell positioning device 30 away from the guide device 10. The pushing device 40 includes a pushing drive and a pushing member 420. The pushing drive is transmission-connected to the pushing member 420 and is used to drive the pushing member 420 to move along the introduction direction of the battery cell to push the battery cell into the battery shell 200.

[0111] As a result, the operation of pushing the battery cell into the battery housing 200 can be made time-saving and labor-saving, and the efficiency of introducing the battery into the battery housing 200 is effectively improved.

[0112] The pushing member 420 may be any one of a pushing block, a pushing plate, a pushing frame, etc., and is not limited here.

[0113] The pushing drive member can have multiple implementation methods. In one possible implementation method, the pushing drive member may include a driving member, the driving end of which is transmission-connected to the pushing member 420, and is used to drive the pushing member 420 to move along the introduction direction to push the battery cell into the battery housing 200. The structure is simple and easy to implement.

[0114] In another possible implementation, as shown in Figures 16 and 17, the pushing drive member includes a pushing lifting drive member 410 and a pushing horizontal drive member 430. The pushing lifting drive member 410 is transmission-connected to the pushing member 420 for driving the pushing member 420 to move in the vertical direction to adjust the central axis of the pushing member 420 to coincide with the central axis of the battery housing 200. The pushing horizontal drive member 430 is transmission-connected to the pushing lifting drive member 410 for driving the pushing lifting drive member 410 to move along the introduction direction of the battery cell, thereby driving the pushing member 420 to move along the introduction direction of the battery cell.

[0115] Thus, the pushing member 420 can be driven to move in the vertical direction by pushing in the lifting drive member 410, so that the central axis of the pushing member 420 extending in the introduction direction coincides with the central axis of the battery housing 200 extending in the introduction direction, and the adjustment is fast and relatively accurate; and the pushing member 420 can be driven to move in the introduction direction by pushing in the horizontal drive member 430, so that pushing the battery cell into the battery housing 200 can be more time-saving and labor-saving.

[0116] Among them, the push-in lifting drive member 410 is transmission-connected to the push-in member 420. The driving end of the push-in lifting drive member 410 can be directly connected to the push-in member 420, or the driving end of the push-in lifting drive member 410 can be connected to the push-in member 420 through a flange, a connecting plate, etc., which is not limited here.

[0117] The push-in lifting drive member 410 can be any one of a pneumatic cylinder, an electric cylinder, a combination of a motor and a gear rack, etc., and is not limited here.

[0118] The structure of the horizontal driving member 430 may be substantially the same as that of the lifting driving member 410 , and will not be described in detail herein.

[0119] In some embodiments, as shown in Figure 16, the shell positioning device 20 has a shell bearing surface 210, which is used to bear the battery shell 200 so that the battery shell 200 is aligned in the vertical direction with the end of the first guide channel 4 or the second guide channel 5 away from the entrance end; the shell positioning device 20 includes a first shell positioning drive member and a second shell positioning drive member, which are used to push the battery shell 200 to move in a horizontal direction perpendicular to the introduction direction of the battery cell so that the battery shell 200 is aligned in the horizontal direction with the end of the first guide channel 4 or the second guide channel 5 away from the entrance end.

[0120] It should be explained that the above-mentioned battery housing 200 is aligned vertically with the end of the first guide channel 4 or the second guide channel 5 away from the inlet end, which means that the center line of the battery housing 200 extending along the introduction direction and the center line of the end of the first guide channel 4 or the second guide channel 5 extending along the introduction direction away from the inlet end are located in the same horizontal plane.

[0121] It should also be explained that the horizontal alignment of the above-mentioned battery housing 200 and the end of the first guide channel 4 or the second guide channel 5 away from the inlet end means that the center line of the battery housing 200 extending along the introduction direction and the center line of the end of the first guide channel 4 or the second guide channel 5 extending along the introduction direction away from the inlet end are located in the same vertical plane.

[0122] Thus, the battery shell 200 can be positioned in the vertical direction through the shell bearing surface 210, so that the center line of the battery shell 200 extending along the introduction direction can be more accurately located in the same horizontal plane as the center line of the first guide channel 4 or the second guide channel 5 extending along the introduction direction, and the position of the battery shell 200 on the shell bearing surface 210 can be adjusted by the first shell positioning drive member and the second shell positioning drive member, so that the center line of the battery shell 200 extending along the introduction direction can be more quickly and accurately located in the same vertical plane as the center line of the first guide channel 4 or the second guide channel 5 extending along the introduction direction, thereby enabling the center line of the battery shell 200 extending along the introduction direction to be more quickly and accurately located in the same straight line as the center line of the first guide channel 4 or the second guide channel 5 extending along the introduction direction.

[0123] In which, the shell positioning device 20 may include a positioning seat, the shell bearing surface 210 may be located on the upper surface of the positioning seat, the first shell positioning drive member and the second shell positioning drive member may be arranged on the shell bearing surface 210 or at other positions of the positioning seat, and the first shell positioning drive member and the second shell positioning drive member are arranged relative to each other in a horizontal direction perpendicular to the introduction direction of the battery cell, and the battery shell 200 can be placed between the first shell positioning drive member and the second shell positioning drive member.

[0124] In addition, the battery shell insertion device 100 further includes a horizontal driving device, which is transmission-connected to the shell positioning device 20 and is used to drive the shell positioning device 20 to move toward or away from the guide device 10 .

[0125] Thus, the housing positioning device 20 can relatively quickly drive the battery housing 200 to move toward or away from the guide device 10, effectively improving the moving speed of the battery housing 200 and improving the efficiency of introducing the battery cells into the battery housing 200.

[0126] The horizontal driving device may be any one of a linear motor, an electric cylinder, a combination of a motor and a rack and pinion, etc., and is not limited here.

[0127] In addition, the structure of the cell positioning device 30 may be substantially the same as that of the housing positioning device 20 . For details, reference may be made to the above description of the structure of the housing positioning device 20 , which will not be repeated here.

[0128] In other embodiments, as shown in FIG. 16 and FIG. 18 , the battery shell insertion device 100 further includes a blanking device 50 , which is used to blank the battery shell 200 into which the battery cells are introduced.

[0129] As a result, the blanking of the battery casing 200 with the battery cells can be time-saving and labor-saving, and the operating efficiency of the battery casing device 100 is effectively improved.

[0130] Among them, the unloading device 50 can have multiple implementation methods. In one possible implementation method, the unloading device 50 may include a driving member and an adsorption member. The driving end of the driving member is connected to the adsorption member to drive the adsorption member to move toward or away from the battery shell 200 with the battery cells introduced. A plurality of vacuum adsorption holes are provided on the adsorption member to vacuum adsorb the battery shell 200 with the battery cells introduced. Then, the battery shell 200 with the battery cells introduced can be moved and unloaded under the drive of the driving member, and the operation is simple and convenient.

[0131] In another possible implementation, as shown in Figures 16 and 18, the unloading device 50 includes a unloading lifting drive member 510, a unloading horizontal drive member 520 and a clamping member 530. The unloading lifting drive member 510 is transmission-connected to the clamping member 530, and is used to drive the central axis of the clamping mouth of the clamping member 530 to coincide with the central axis of the battery shell 200. The unloading horizontal drive member 520 is transmission-connected to the unloading lifting drive member 510, and is used to drive the unloading lifting drive member 510 to move in a direction close to or away from the shell positioning device 20, thereby driving the clamping member 530 to move in a direction close to or away from the shell positioning device 20.

[0132] Thus, the clamping member 530 can be driven to rise and fall by the blanking lifting drive member 510, so that the center line of the clamping mouth of the clamping member 530 extending along the introduction direction can be more quickly and accurately coincided with the center line of the battery shell 200 extending along the introduction direction, so that when the clamping member 530 is driven by the blanking horizontal drive member 520 to move toward the position of the battery shell 200 close to the shell positioning device 20, the battery shell 200 with the battery cells introduced can be clamped quickly and accurately, effectively improving the blanking efficiency of the battery shell 200 with the battery cells introduced.

[0133] Among them, the transmission connection between the unloading lifting drive member 510 and the clamping member 530 can be roughly the same as the transmission connection between the above-mentioned pushing lifting drive member 410 and the pushing member 420. Please refer to the above for details and will not be repeated here.

[0134] The horizontal driving member 520 for blanking is connected to the lifting driving member 510 in a transmission manner, which can be roughly the same as the transmission connection between the pushing lifting driving member 410 and the pushing member 420 mentioned above, and will not be repeated here.

[0135] In addition, the structure of the blanking lifting drive member 510 can be substantially the same as that of the push-in lifting drive member 410. For details, please refer to the above and will not be repeated here. The structure of the blanking horizontal drive member 520 can be substantially the same as that of the push-in horizontal drive member 430 and will not be repeated here.

[0136] Optionally, the lower surface of the battery shell 200 may be partially in a suspended state, as shown in Figure 18, the clamping member 530 includes a first clamping claw 5310 and a second clamping claw 5320, the first clamping claw 5310 and the second clamping claw 5320 are used to clamp the upper surface and lower surface of the battery shell 200, respectively, the lower surface of the battery shell 200 is configured as the side of the battery shell 200 facing the shell bearing surface 210, and the upper surface of the battery shell 200 is configured as the side of the battery shell 200 facing away from the shell bearing surface 210.

[0137] Thus, the clamping member 530 can clamp the battery housing 200 more stably.

[0138] Moreover, when the battery shell 200 is a square shell and the upper surface and the lower surface of the battery shell 200 are the two large surfaces of the battery shell 200, the first clamping claw 5310 and the second clamping claw 5320 can be made to clamp the battery shell 200 more easily even if the center line of the clamping mouth of the clamping member 530 extending along the introduction direction does not completely coincide with the center line of the battery shell 200 extending along the introduction direction. At the same time, it is also convenient to make the clamping surfaces of the first clamping claw 5310 and the second clamping claw 5320 wider, so that there can be a larger contact area between the clamping member 530 and the battery shell 200, so that the clamping member 530 can clamp the battery shell 200 more firmly.

[0139] In addition, the clamping member 530 may also include a clamping drive member, the driving end of which can be connected to the first clamping jaw 5310 and / or the second clamping jaw 5320, and is used to adjust the distance between the first clamping jaw 5310 and the second clamping jaw 5320, so that the distance between the first clamping jaw 5310 and the second clamping jaw 5320 can be adjusted according to the distance between the upper surface and the lower surface of the battery shell 200, so that the clamping member 530 can clamp the battery shell 200 more firmly while also clamping battery shells 200 of different sizes and models, thereby improving the applicability of the unloading device 50.

[0140] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present disclosure.
