Description

Technical Field

[0001] This invention relates to the field of shell insertion technology, and in particular to a shell insertion device, shell insertion equipment, and shell insertion method. Background Technology

[0002] In the battery production process, the battery cells need to be placed inside the casing to ensure that they are immersed in the electrolyte, enabling the transfer of ions on the positive and negative electrodes and thus generating current. However, existing casing insertion devices require inverting the casing before inserting the battery cells from bottom to top. This method is complex and cumbersome, resulting in excessively large equipment size and frequent downtime. Summary of the Invention

[0003] Therefore, it is necessary to provide a shell insertion device, shell insertion equipment, and shell insertion method that improves upon the aforementioned defects, addressing the problems of complex structure and cumbersome operation of existing shell insertion devices.

The centering mechanism includes centering jaws, each jaw comprising a first clamping portion and a second clamping portion arranged sequentially along a first direction. The first clamping portion is used to clamp the battery cell, and the second clamping portion is used to clamp the area of ​​the housing near the housing opening. The geometric centers of the first clamping portion and the second clamping portion coincide, and the projection of the first clamping portion along the first direction is located within the second clamping portion.

Therefore, the pushing mechanism can push the battery cell into the casing from top to bottom, so that the casing does not need to be flipped or inverted before and after insertion. This simplifies the structure and workflow of the casing insertion device and improves the efficiency of battery insertion.

[0094] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0095] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0096] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0097] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly.

The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0100] To better understand the embodiments of this application, the following is combined with... Figures 1 to 18 The embodiments of this application will be described in detail.

[0101] like Figures 1 to 15 As shown, this application provides a casing device 1 for inserting a battery cell 2 into a housing 3. The casing device 1 includes a mounting component 11, a centering mechanism 12, and a pushing mechanism 13. The centering mechanism 12 is disposed on the mounting member 11. The centering mechanism 12 includes a centering gripper 121. The centering gripper 121 includes a first clamping part 1211 and a second clamping part 1212 arranged sequentially along the first direction X. The first clamping part 1211 is used to clamp the battery cell 2. The second clamping part 1212 of the housing 3 is used to clamp the area of ​​the housing 3 near the opening of the housing. The geometric centers of the first clamping part 1211 and the second clamping part 1212 coincide, and the projection of the first clamping part 1211 along the first direction X is located in the second clamping part 1212. The pushing mechanism 13 is disposed on the side of the centering mechanism 12 near the first clamping part 1211. The pushing mechanism 13 is movably disposed on the mounting member 11 along the first direction X, and the pushing mechanism 13 includes a pushing rod 131 extending along the first direction X, used to push the battery cell 2 into the housing 3.

[0102] Cell 2 refers to a component formed by stacking or winding positive and negative electrode plates and a separator. Cell 2 can be a lithium-ion battery, lithium-sulfur battery, sodium-lithium-ion battery, sodium-ion battery, or magnesium-ion battery, etc., and this application embodiment does not limit this. The shape of cell 2 can be cylindrical, flat, cuboid, or other shapes, and this application embodiment also does not limit this.

[0103] The housing 3 refers to an open accommodating component that houses the battery cell 2 and the electrolyte, thereby enabling the exchange of ions on the positive and negative electrode plates in the battery cell 2 and generating current. The housing 3 can be made of materials such as aluminum or copper, and this embodiment does not limit its material. The shape of the housing 3 is also not limited in this embodiment.

[0104] Mounting component 11 refers to the component that mounts the centering mechanism 12, the pushing mechanism 13, and other mechanisms. The centering mechanism 12 can be movably mounted on the mounting component 11 to adjust the relative position between the pushing mechanism 13 and the centering mechanism 12, thereby accelerating the insertion speed of the battery cell 2 into the casing. Alternatively, the centering mechanism 12 can be fixedly mounted on the mounting component 11 to increase its stability during insertion into the casing, ensuring that the battery cell 2 is smoothly inserted into the casing 3.

[0105] like Figure 8 As shown, the geometric centers of the first clamping portion 1211 and the second clamping portion 1212 on the centering jaw 121 coincide. This means that when the centering jaw 121 clamps the battery cell 2 and the housing 3, their geometric centers also coincide, ensuring the concentricity of the battery cell 2 and the housing 3. This ensures that when the battery cell 2 is inserted into the housing 3, the gap between the outer periphery of the battery cell 2 and the inner wall of the housing 3 is uniform, preventing damage to the battery cell 2 due to squeezing or collision, or even short circuits. The second clamping portion 1212 is used to clamp the area of ​​the housing 3 near the opening, meaning the housing 3 is clamped with its opening facing upwards in the second clamping portion 1212.

[0106] The projection of the first clamping part 1211 along the first direction X is located inside the second clamping part 1212. That is, while ensuring the concentricity of the first clamping part 1211 and the second clamping part 1212, the size of the first clamping part 1211 is smaller than the size of the second clamping part 1212. This ensures that the outer periphery of the battery cell 2 is located inside the inner wall of the housing 3 after clamping, which can further prevent the battery cell 2 from being squeezed and collided with the housing 3 during insertion and thus prevent damage to the battery cell 2, thereby improving the safety and effectiveness of insertion.

[0107] The pushing mechanism 13 is located on the side of the centering mechanism 12 near the first clamping part 1211. That is, when the pushing mechanism 13 moves towards the centering mechanism 12, the pushing mechanism 13 can come into contact with the battery cell 2, thereby pushing the battery cell 2 into the housing 3 and completing the housing insertion process.

[0108] The pushing mechanism 13 is movably disposed on the mounting member 11 along the first direction X. That is, the pushing mechanism 13 can move relative to the mounting member 11 along the first direction, thereby moving closer to or away from the centering mechanism 12 to push the battery cell 2 into the housing 3. Specifically, the pushing mechanism 13 can be movably connected relative to the mounting member 11 along the first direction through a guide rail slider mechanism or a gear rack mechanism.

[0109] The pushing mechanism 13 includes a pushing rod 131 extending along the first direction X. That is, the pushing rod 131 protrudes along the first direction 13 and is disposed on the pushing mechanism 13. By setting the pushing rod 131, the battery cell 2 can be pushed. This can prevent the battery cell 2 from being completely pushed into the housing 3 due to insufficient space between the pushing mechanism 13 and the centering mechanism 12 (for example, when a battery cell clamping mechanism 14 is provided between the pushing mechanism 13 and the centering mechanism, the pushing rod 131 can avoid the battery cell clamping mechanism 14 when pushing the battery cell 2). This can ensure that the battery cell 2 is completely installed in the housing 3.

[0110] By setting the centering mechanism 12 and the pushing mechanism 13, the centering of the battery cell 2 and the housing 3 can be achieved. In addition, the housing 3 is clamped in the second clamping part 1212 with the opening facing upward. Therefore, the pushing mechanism 13 can push the battery cell 2 into the housing 3 from top to bottom, so that the housing 3 does not need to be flipped or inverted before and after entering the housing. This simplifies the structure and workflow of the housing entry device 1 and improves the efficiency of battery entry.

[0111] like Figure 1 and Figure 3 As shown, in some embodiments, the centering gripper 121 is a split structure, and the centering mechanism 12 further includes a first driving part 122 that is drivenly connected to the centering gripper 121 for driving the centering gripper 121 to open or close.

[0112] The centering jaw 121 is a split structure, meaning it consists of at least two parts. The opening and closing of the centering jaw 121 is achieved by adjusting the distance between these parts, thereby clamping and releasing the battery cell 2 and the housing 3. Specifically, the centering jaw 121 can be a robotic arm, which opens and closes to achieve clamping and releasing; alternatively, the centering jaw 121 can also be a three-jaw chuck, which can also clamp and release the components.

[0113] The first drive unit 122 can be an electric motor, or a cylinder, electric cylinder, hydraulic cylinder, etc. The first drive unit 122 is drivenly connected to the centering gripper 121, thereby providing driving force to the centering gripper 121 to control its clamping and releasing.

[0114] By setting the centering gripper 121 as a separate structure, it is easy to load and unload the battery cell 2 and the housing 3.

[0115] like Figure 1As shown in 3 and 5 to 10, in some embodiments, the centering gripper 121 further includes a centering mount 1213, a centering rotatable seat 1214, and a centering clamping member 1215. The centering rotating seat 1214 is rotatably mounted on the centering mounting member 1213. The centering rotating seat 1214 is provided with a first sliding groove 12141. The first driving part 122 is drivenly connected to the centering rotating seat 1214 to drive the centering rotating seat 1214 to rotate. The centering clamping member 1215 is disposed on one side of the centering rotating seat 1214 along the first direction X. The centering clamping member 1215 includes a first clamping jaw 12151 and a second clamping jaw 12152 disposed at intervals along the second direction Y. One end of the first clamping jaw 12151 and the second clamping jaw 12152 are respectively movably disposed in the first sliding groove 12141, and the other end is respectively movably disposed on the centering mounting member 12143 along the second direction Y. The second direction Y is perpendicular to the first direction X, and the first clamping part 1211 and the second clamping part 1212 are respectively disposed on both sides of the first clamping jaw 12151 and / or the second clamping jaw 12152 along the first direction X.

[0116] The centering rotating seat 1214 is rotatably mounted on the centering mounting member 1213. Specifically, a rotating shaft can be set, with one end of the shaft rotatably inserted into the centering mounting member 1213 and the other end fixedly connected to the centering rotating seat 1214. The rotation of the rotating shaft realizes the rotation of the centering rotating seat 1214 relative to the centering mounting member 1213.

[0117] The centering rotary seat 1214 is provided with a first sliding groove 12141. When the centering rotary seat 1214 rotates relative to the centering mounting part 1213, the extension direction of the first sliding groove 12141 will also change accordingly.

[0118] The first drive unit 122 can be a motor that drives the centering rotary seat 1214 to rotate relative to the centering mounting member 1213; the first drive unit 122 can also be a cylinder, electric cylinder, hydraulic cylinder, cam mechanism, etc., which pushes the centering rotary seat 1214 to rotate (i.e., swing) relative to the mounting member 1213 within a certain range through linear motion.

[0119] like Figure 9 As shown, in the triangle, the distance d between the first gripper 12151 and the second gripper 12152 along the second direction can be expressed as: d = h / tana; where h is the height difference between the first gripper 12151 and the second gripper 12152 in the first direction X, and a is the angle between the first slide groove 12141 and the second direction Y.

[0120] One end of the first gripper 12151 and the second gripper 12152 are movably disposed in the first slide groove 12141. When the centering rotary seat 1214 rotates relative to the centering mounting member 1213, the included angle α between the first slide groove 12141 and the second direction Y will change accordingly. The other ends of the first gripper 12151 and the second gripper 12152 are movably disposed in the centering mounting member 12143 along the second direction Y. That is, when the first gripper 12151 and the second gripper 12152 move along the second direction Y relative to the centering mounting member 12143, the height difference h between the two in the first direction X will not change.

[0121] That is, when the centering rotary seat 1214 rotates relative to the centering mounting member 1213, the angle α between the first slide groove 12141 and the second direction Y will change accordingly. However, the height difference h between the first gripper 12151 and the second gripper 12152 in the first direction X remains constant. Therefore, the distance d between the first gripper 12151 and the second gripper 12152 in the second direction Y will change with the rotation of the centering rotary seat 1214. Thus, by adjusting the rotation angle and direction of the centering rotary seat 1214, the first gripper 12151 and the second gripper 12152 can move closer or further apart in the second direction Y, thereby realizing the clamping and releasing of the centering mechanism 12.

[0122] The first clamping part 1211 and the second clamping part 1212 are respectively disposed on both sides of the first jaw 12151 and / or the second jaw 12152 along the first direction X. That is, in some embodiments, one of the first jaw 12151 and the second jaw 12152 is provided with the first clamping part 1211 and the second clamping part 1212 on both sides of the first direction X to clamp the battery cell 2 and the housing 3 respectively. In other embodiments, the first jaw 12151 and the second jaw 12152 are provided with the first clamping part 1211 and the second clamping part 1212 on both sides of the first direction X, which can further ensure the stability and concentricity of the battery cell 2 and the housing 3 clamped on the first jaw 12151 and the second jaw 12152.

[0123] By setting up a centering rotary seat 1214 and a centering clamping member 1215, the centering clamping member 1215 can be clamped and released by controlling the rotation direction and angle of the centering rotary seat 1214. The structure is ingenious and the movement is reliable.

[0124] like Figure 6As shown, in some embodiments, the centering clamping member 1215 further includes: a first roller 12153, wherein a first gripper 12151 is movably disposed in a first groove 12141 via the first roller 12153; and / or a second roller 12154, wherein a second gripper 12152 is movably disposed in a first groove 12141 via the second roller 12154.

[0125] That is, in some embodiments, the centering clamp 1215 further includes one of the first roller 12153 and the second roller 12154; while in other embodiments, the centering clamp 1215 includes both the first roller 12153 and the second roller 12154.

[0126] The first roller 12153 and the second roller 12154 are components that can roll around their own axes. The first gripper 12151 is movably mounted in the first groove 12141 via the first roller 12153. This converts the sliding friction of the first gripper 12151 moving within the first groove 12141 into rolling friction of the first roller 12153 within the same groove. This reduces wear between the first gripper 12151 and the first groove 12141, thus increasing the service life of the centering mechanism 12. The function of the second roller 12154 is similar to that of the first roller 12153, and will not be described further here.

[0127] like Figure 5 and Figure 6 As shown, in some embodiments, the centering mounting member 1213 is provided with a first guide rail 12131 extending along the second direction Y, and the first gripper 12151 and the second gripper 12152 are respectively provided with a first slider 121511 and a second slider 121521, and the first slider 121511 and the second slider 121521 are respectively movably disposed on the first guide rail 12131.

[0128] The movement of the first gripper 12151 and the second gripper 12152 relative to the centering mounting member 1213 is achieved by setting the first guide rail 12131, the first slider 121511 and the second slider 121521. The structure is simple and highly reliable.

[0129] like Figure 3 , 5 As shown in Figure 6, in some embodiments, the centering gripper 121 further includes a first elastic member 1216, which extends along the second direction Y, and one end of the first elastic member 1216 is connected to the first gripper 12151, and the other end is connected to the second gripper 12152.

[0130] The first elastic element 1216 refers to an elastic component, which can be rubber or a spring. The first elastic element 1216 connects the first gripper 12151 and the second gripper 12152. When the centering gripper 121 clamps the battery cell 2 and the housing 3, the first elastic element 1216 can provide elastic force to increase the clamping force between the first gripper 12151 and the second gripper 12152, thereby improving the stability of the battery cell 2 and the housing 3 on the centering gripper 121.

[0131] like Figure 5 and Figure 6 As shown, in some embodiments, the centering gripper 121 further includes a first connector 1217. One end of the first connector 1217 is connected to the centering rotary seat 1214, and the other end is abutted by the first drive part 122. The first drive part 122 and / or the centering gripper 121 are movably disposed on the mounting member 11 along the first direction X to drive the first connector 1217 to swing.

[0132] One end of the first connector 1217 is connected to the centering rotary seat 1214. Specifically, the first connector 1217 can be integrally formed with the centering rotary seat 1214, or it can be manufactured separately and then assembled together by welding, bolting or other methods.

[0133] The first drive unit 122 and / or the centering gripper 121 are movably disposed on the mounting member 11 along the first direction X. That is, in some embodiments, one of the first drive unit 122 and the centering gripper 121 is movably disposed on the mounting member 11 along the first direction X; while in other embodiments, both the first drive unit 122 and the centering gripper 121 are movably disposed on the mounting member 11 along the first direction X. Specifically, a guide rail extending along the first direction can be provided on the mounting member 11, and a slider can be provided on the first drive unit 122 and / or the centering gripper 121. The relative position of the first drive unit 122 and the centering gripper 121 in the first direction X can be adjusted by the movement of the slider on the guide rail, thereby causing the first drive unit 122 and the first connecting member 1217 to approach and abut against each other to push the centering rotary seat 1214 to swing relative to the centering mounting member 12133.

[0134] By setting the first connecting member 1217, the centering rotating seat 1214 is configured as a rotatable connecting rod mounted on the centering mounting member 1213. When the first driving part 122 and / or the centering gripper 121 move along the first direction X, the first driving part 122 and the centering gripper 121 can move closer to each other, so that the first driving part 122 abuts against the first connecting member 1217 to push the centering rotating seat 1214 to swing relative to the centering mounting member 12133, thereby realizing the clamping and loosening of the battery cell 2 and the housing 3. The structure is simple and easy to control.

[0135] Furthermore, through the arrangement of the first driving unit 122 and the first elastic member 1216, when the first driving unit 122 and the centering jaw 121 approach each other along the first direction X, the first driving unit 122 can push the centering rotating seat 1214 to rotate, thereby causing the first jaw 12151 and the second jaw 12152 to move away from each other and open the centering jaw 121, so as to facilitate the loading of the battery cell 2 and the housing 3. After the loading is completed, the first driving unit 122 and the centering jaw 121 move away from each other along the first direction X, and the first jaw 12151 and the second jaw 12152 approach each other along the second direction Y under the drive of the elastic force of the first elastic member 1216, thereby clamping the battery cell 2 and the housing 3 while driving the centering rotating seat 1214 to rotate in the opposite direction and return to the initial position.

[0136] In summary, by setting the first driving part 122 and the first elastic element 1216, not only can the driving force when the centering claw 121 clamps be eliminated, but the control of clamping and releasing the centering claw 121 can also be made simpler and more reliable.

[0137] like Figure 6 and Figure 9 As shown, in some embodiments, the distance along the first direction X between the connection position of the first gripper 12151 and the first slide groove 12141 and the connection position of the second gripper 12152 and the first slide groove 12141 is greater than zero and less than or equal to the length of the first slide groove 12141.

[0138] The distance along the first direction X between the connection position of the first gripper 12151 and the first slide groove 12141 and the connection position of the second gripper 12152 and the first slide groove 12141 is greater than zero. That is, there is a certain height difference h between the first gripper 12151 and the second gripper 12152 along the first direction X. According to d = h / tana, only when h is not zero can the distance d between the first gripper 12151 and the second gripper 12152 change with the change of the included angle a. Only then can the clamping and loosening of the battery cell 2 and the housing 3 be achieved by rotating the centering rotating seat 1214.

[0139] However, when the distance along the first direction X between the connection position of the first gripper 12151 and the first slide groove 12141 and the connection position of the second gripper 12152 and the first slide groove 12141 is greater than the length of the first slide groove 12141, the first gripper 12151 and the second gripper 12152 will be able to disengage from the first slide groove 12141. Therefore, in order to ensure the normal operation of the centering gripper 121, it is also necessary to ensure that the height difference between the first gripper 12151 and the second gripper 12152 along the first direction X is less than or equal to the length of the first slide groove 12141.

[0140] like Figure 1 , 2As shown in 9 to 14, in some embodiments, the housing device 1 further includes a cell clamping mechanism 14 disposed along the first direction X between the pushing mechanism 13 and the centering mechanism 12.

[0141] The battery cell clamping mechanism 14 refers to the component used to clamp and fix the battery cell 2. Specifically, the battery cell clamping mechanism 14 can be a separate mechanism such as a robotic arm three-jaw chuck, which achieves clamping and releasing of the battery cell by the mutual approach and distance of the two parts.

[0142] In some embodiments, the cell clamping mechanism 14 is fixedly mounted on the mounting member 11. When the cell 2 is inserted into the housing, it can limit and fix the cell 2, preventing it from becoming misaligned due to insufficient clamping force of the centering mechanism 12 if the size of the cell 2 along the first direction X is too large. This would prevent the cell 2 from rubbing against the outer wall of the housing 3 when inserted into the housing 3, thus damaging the cell 2. In other embodiments, the cell clamping mechanism 14 is movably mounted on the mounting member 11 along the first direction X. When the cell 2 is inserted into the housing 3, the cell clamping mechanism 14 can also gradually move closer to the housing 3 along the first direction X, making the insertion process of the cell 2 more stable and further improving the quality of the cell 2 insertion process.

[0143] By setting a cell clamping mechanism 14 between the pushing mechanism 13 and the centering mechanism 12, the concentricity of the cell 2 and the housing 3 and the stability of the insertion process can be improved during the insertion of the cell 2 into the housing, thereby further ensuring the quality of the insertion process.

[0144] like Figure 1 and 2 As shown, in some embodiments, the battery cell clamping mechanism 14 includes a battery cell gripper 141 and a second driving part 142. The battery cell gripper 141 is a split structure; the second driving part 142 is drivenly connected to the battery cell gripper 141 to drive the battery cell gripper 141 to open or close.

[0145] Similarly, the cell clamp 141 is a split structure, meaning it consists of at least two parts, allowing it to open or close to clamp and release the cell 2. Specifically, the center clamp 121 can be a robotic arm or a three-jaw chuck to clamp and release the cell 2.

[0146] The second drive unit 142 can be a motor, or a cylinder, electric cylinder, hydraulic cylinder, etc. The second drive unit 142 is driven to connect with the battery cell gripper 141, thereby providing driving force to the battery cell gripper 141 to control its clamping and releasing.

[0147] like Figure 2As shown in 9 to 14, in some embodiments, the cell clamp 141 includes a cell clamping mounting member 1411, a cell clamping rotating seat 1412, and a cell clamping member 1413. The battery cell clamping mounting component 1411 includes a second guide rail 14111 extending along the second direction Y; a battery cell clamping rotating seat 1412 is rotatably disposed on the battery cell clamping mounting component 1411, and a second sliding groove 14121 is provided on the battery cell clamping rotating seat 1412; a second driving part 142 is drivenly connected to the battery cell clamping rotating seat 1412 to drive the battery cell clamping rotating seat 1412 to rotate; a battery cell clamping component 1413 is disposed on one side of the battery cell clamping rotating seat 1412 along the first direction X, and the battery cell clamping component 1413 includes a third clamping claw 14131 and a fourth clamping claw 14132 spaced apart along the second direction Y; one end of the third clamping claw 14131 and the fourth clamping claw 14132 is movably disposed in the second sliding groove 14121, and the other end is movably connected to the second guide rail 14111 through the third slider 141311 and the fourth slider 141321, respectively.

[0148] Similarly, the second slide groove 14121 is set on the cell clamping rotating seat 1412. When the cell clamping rotating seat 1412 rotates relative to the cell clamping mounting part 1411, the extension direction of the second slide groove 14121 will also change accordingly, thereby changing the angle α between the second slide groove 14121 and the second direction Y, and thus adjusting the distance between the third jaw 14131 and the fourth jaw 14132 along the second direction Y, so as to achieve clamping and loosening of the cell 2.

[0149] The second drive unit 142 can be a motor that drives the centering rotary seat 1214 to rotate relative to the battery cell clamping mounting member 1411; the second drive unit 142 can also be a cylinder, electric cylinder, hydraulic cylinder, cam mechanism, etc., which pushes the centering rotary seat 1214 to rotate (i.e., swing) relative to the mounting member 1213 within a certain range through linear motion.

[0150] like Figure 9 As shown, in the triangle, the distance d between the third gripper 14131 and the fourth gripper 14132 along the second direction can also be expressed as: d = h / tana; where h is the height difference between the third gripper 14131 and the fourth gripper 14132 in the first direction X, and a is the angle between the second slide groove 14121 and the second direction Y.

[0151] Similarly, when the cell clamping rotating seat 1412 rotates relative to the cell clamping mounting part 1411, the angle α between the second slide groove 14121 and the second direction Y will change accordingly. However, the height difference h between the third gripper 14131 and the fourth gripper 14132 in the first direction X remains constant. Therefore, the distance d between the third gripper 14131 and the fourth gripper 14132 in the second direction Y will change with the rotation of the cell clamping rotating seat 1412. Thus, by adjusting the rotation angle and direction of the cell clamping rotating seat 1412, the third gripper 14131 and the fourth gripper 14132 can move closer or further apart in the second direction Y, thereby realizing the clamping and releasing of the cell clamping mechanism 14.

[0152] By setting up a cell clamping rotating seat 1412 and a centering clamping member 1215, the clamping and releasing of the centering clamping member 1215 can be achieved by controlling the rotation direction and angle of the cell clamping rotating seat 1412. The structure is ingenious and the movement is reliable.

[0153] In some embodiments, the third gripper 14131 and / or the fourth gripper 14132 can also be movably disposed within the second groove 14121 via rollers. In this way, the sliding friction of the third gripper 14131 moving within the second groove 14121 can be converted into rolling friction of the rollers within the second groove 14121, reducing wear between the third gripper 14131 and the second groove 14121 and improving the service life of the cell clamping mechanism 14. The fourth gripper 14132 serves the same purpose as the rollers, and will not be described further here.

[0154] like Figure 2 As shown in 10 to 14, in some embodiments, the cell clamp 141 further includes a second elastic member 1414, which extends along the second direction Y, and one end of the second elastic member 1414 is connected to the third clamp 14131, and the other end is connected to the fourth clamp 14132.

[0155] The second elastic element 1414 can be rubber or a spring. The second elastic element 1414 connects the third jaw 14131 and the fourth jaw 14132. When the battery cell jaw 141 clamps the battery cell 2, the second elastic element 1414 can provide elastic force to increase the clamping force between the third jaw 14131 and the fourth jaw 14132, thereby improving the stability of the battery cell 2 on the battery cell jaw 141.

[0156] like Figure 10 , 12As shown in Figure 14, in some embodiments, the cell gripper 141 further includes a second connector 1415. One end of the second connector 1415 is connected to the cell clamping rotating seat 1412, and the other end is abutted by the second drive part 142. The second drive part 142 and / or the cell gripper 141 are movably disposed on the mounting member 11 along the first direction X to drive the second connector 1415 to swing.

[0157] One end of the second connector 1415 is connected to the cell clamping rotating seat 1412. Specifically, the second connector 1415 can be integrally formed with the cell clamping rotating seat 1412, or it can be manufactured separately and then combined and connected together by welding, bolting or other methods.

[0158] The second drive unit 142 and / or the cell clamp 141 are movably disposed on the mounting member 11 along the first direction X. That is, in some embodiments, one of the second drive unit 142 and the cell clamp 141 is movably disposed on the mounting member 11 along the first direction X; while in other embodiments, both the second drive unit 142 and the cell clamp 141 are movably disposed on the mounting member 11 along the first direction X. Specifically, a guide rail extending along the first direction X can be provided on the mounting member 11, and a slider can be provided on the second drive unit 142 and / or the cell clamp 141. The relative position between the second drive unit 142 and the cell clamp 141 can be adjusted by moving the slider on the guide rail.

[0159] By setting the second connector 1415, the cell clamping rotating seat 1412 is configured as a rotatable connecting rod mounted on the cell clamping mounting member 1411. By adjusting the relative distance between the second drive part 142 and / or the cell clamping claw 141 along the first direction X, the second drive part 142 and the cell clamping claw 141 can be brought closer to each other, so that the second drive part 142 abuts against the second connector 1415 to push the cell clamping rotating seat 1412 to swing relative to the cell clamping mounting member 14113, thereby realizing the clamping and loosening of the cell 2. The structure is simple and easy to control.

[0160] Furthermore, through the provision of the second drive unit 142 and the second elastic member 1414, when the second drive unit 142 and the cell clamping jaw 141 approach each other along the first direction X, the second drive unit 142 can push the cell clamping rotating seat 1412 to rotate, thereby causing the third jaw 14131 and the fourth jaw 14132 to move away from each other and open the cell clamping jaw 141, facilitating the loading of the cell 2. After loading is completed, the second drive unit 142 and the cell clamping jaw 141 move away from each other along the first direction X, while the third jaw 14131 and the fourth jaw 14132 approach each other along the second direction under the drive of the elastic force of the second elastic member 1414, thereby clamping the cell 2 while simultaneously driving the cell clamping rotating seat 1412 to rotate in the opposite direction and return to the initial position. In summary, by providing the second drive unit 142 and the second elastic member 1414, not only can the driving force when the cell clamping claw 141 is clamped be eliminated, but the control of clamping and releasing the cell clamping claw 141 can also be made simpler and more reliable.

[0161] like Figure 12 and 14 As shown, in some embodiments, the cell clamping mechanism 14 and / or the centering mechanism are movably disposed on the mounting member 11 along the first direction X. The cell clamping claw 141 also includes a protrusion 1416 disposed on the side of the cell clamping member 1413 near the cell 2. The protrusion 2416 includes a first protrusion 14161 that is buoyantly disposed on the side of the third claw 14131 near the fourth claw 14132; and / or a second protrusion 14162 that is buoyantly disposed on the side of the fourth claw 14132 near the third claw 14131.

[0162] The cell clamping mechanism 14 and / or the centering mechanism 12 are movably disposed on the mounting member 11 along the first direction X. That is, in some embodiments, one of the centering mechanism 12 and the cell clamping mechanism 14 is movably disposed on the mounting member 11 along the first direction X; while in other embodiments, both the centering mechanism 12 and the cell clamping mechanism 14 are movably disposed on the mounting member 11 along the first direction X. Specifically, a guide rail extending along the first direction X can be provided on the mounting member 11, and a slider can be provided on the centering mechanism 12 and / or the cell clamping mechanism 14. The movement of the slider on the guide rail realizes the movement of the centering mechanism 12 and / or the cell clamping mechanism 14 relative to the mounting member 11.

[0163] The cell clamping mechanism 14 and / or the centering mechanism 12 are movably disposed on the mounting member 11 along the first direction X. When the cell 2 is inserted into the housing 3, the cell clamping mechanism 14 and / or the centering mechanism 12 can also move closer to each other along the first direction X. That is, when the cell 2 is inserted into the housing 3 along the first direction X, it can be clamped in the cell clamping mechanism 14, making the process of inserting the cell 2 into the housing more stable and further improving the quality of the process of inserting the cell 2 into the housing.

[0164] In some embodiments, the protrusion 2416 includes one of a first protrusion 14161 and a second protrusion 14162. In other embodiments, the protrusion 2416 includes both the first protrusion 14161 and the second protrusion 14162.

[0165] The protrusion 2416 includes a first protrusion 14161 that is buoyantly disposed on the side of the third gripper 14131 near the fourth gripper 14132. That is, by setting the floating first protrusion 14161, the clamping force between the third gripper 14131 and the fourth gripper 14132 is limited.

[0166] Therefore, when the cell clamping mechanism 14 and / or the centering mechanism 12 move closer to each other along the first direction X to insert the cell 2 into the housing 3, the floating first protrusion 14161 and / or the second protrusion 14162 can provide clamping force for the cell 2, thereby ensuring that the cell 2 can be smoothly inserted into the housing 3. On the other hand, since the clamping force provided by the floating first protrusion 14161 and / or the second protrusion 14162 is limited, when the cell 2 and the housing 3 encounter resistance when the cell 2 is inserted into the housing 3 due to insufficient concentricity, the cell 2 may not be able to enter the housing due to insufficient clamping force and thus cannot generate enough friction between the cell 2 and the cell clamping member 1413 (at this time, only the cell clamping mechanism 14 and the cell 2 move relative to each other, while there is no relative movement between the cell 2 and the housing 3). Thus, it can prevent the cell 2 from being forcibly inserted into the housing 3 and damaging the cell 2 or the housing 3.

[0167] like Figure 12 As shown, in some embodiments, the cell clamp 141 further includes a rotating rod 1417 corresponding to the protrusion 1416 and a third elastic member 1418 disposed between the protrusion 1416 and the rotating rod 1417, and the rotating rod 1417 is spirally disposed on the cell clamp 1413 to adjust the compression degree of the third elastic member 1418.

[0168] A third elastic element 1418 is disposed between the protrusion 1416 and the rotating rod 1417, providing a floating force for the protrusion 1416 through the elastic force of the third elastic element 1418. The rotating rod 1417 is spirally disposed on the cell clamping member 1413. By rotating the rotating rod 1417, the relative distance between the rotating rod 1417 and the protrusion 1416 can be adjusted, thereby adjusting the degree of compression of the third elastic element 1418 and providing different elastic forces to the protrusion 1416 to adapt to different casing processes.

[0169] like Figure 1 , 2As shown in Figure 4, in some embodiments, the pushing mechanism 13 further includes a fourth elastic member disposed on the side of the pushing mechanism 13 near the first clamping part 1211. The height of the fourth elastic member along the first direction X is less than the height of the pushing rod 131. When the pushing mechanism 13 moves along the first direction X, the fourth elastic member abuts against the battery cell clamping mechanism 14.

[0170] like Figure 1 , 3 As shown in Figures 4 and 7, in some embodiments, the centering mechanism 12 and / or the cell clamping mechanism 14 are movably disposed on the mounting member 11 along the first direction X, and the housing device 1 further includes a limiting member 15 disposed between the cell clamping mechanism 14 and the centering mechanism 12 for limiting the relative distance between the cell clamping mechanism 14 and the centering mechanism 12 along the first direction X.

[0171] like Figure 1 , 3 As shown in Figure 4, in some embodiments, the housing device 1 further includes a housing positioning mechanism 16, which is disposed along the first direction X on the side of the centering mechanism 12 away from the pushing mechanism 13. The housing positioning mechanism 16 includes a first positioning part 161 and a second positioning part 162 disposed at intervals along the first direction X.

[0172] By setting the housing positioning mechanism 16, the housing 3 can be further fixed when it is inserted into the housing, preventing the housing 3 from tilting during the insertion process, further ensuring the concentricity of the battery cell 2 and the housing 3, and improving the quality of the battery cell 2 being inserted into the housing.

[0173] Specifically, the housing positioning mechanism 16 can be a clamping member, which clamps and releases the housing 3 by opening and closing the clamping member; in addition, the housing positioning mechanism 16 can also be an adsorption member, which adsorbs and fixes the housing 3 in the housing positioning mechanism 16 by adsorption force.

[0174] For example, in some embodiments, the housing positioning mechanism 16 may be provided with an adsorption member on the side near the housing 3. The adsorption member may be a negative pressure device that uses the generated negative pressure to adsorb and fix the housing 3 onto the housing positioning mechanism 16; in addition, the adsorption member may be a magnetic adsorption device that uses the electromagnetic force generated by an electromagnet or a permanent magnet to adsorb the housing 3 onto the housing positioning mechanism 16.

[0175] like Figure 4As shown, in some embodiments, the housing positioning mechanism 16 further includes a base plate 163, a top rod 164, and a third driving part 165. The base plate 163 is disposed on the side of the housing positioning mechanism 16 opposite to the centering mechanism 12, and a first through hole 1631 is provided on the base plate 163. The top rod 164 passes through the first through hole 1631. The third driving part 165 is drivenly connected to the top rod 164 to drive the top rod 164 to move along a first direction X, thereby lifting the housing 3 in the housing positioning mechanism 16.

[0176] When the battery cell 2 arrives, the housing 3 rests on the base plate 163. During loading, the third drive mechanism 165 drives the push rod 164 to move along the first direction X, thereby lifting the housing 3 from the base plate 163 and into the centering mechanism 12, completing the assembly of the battery cell 2 and the housing 3. After the battery cell 2 is installed in the housing, the housing 3 falls back onto the base plate 163 under the push of the push mechanism 13, so as to carry out subsequent unloading, transfer and other operations.

[0177] In some embodiments, such as Figure 1 and Figure 4 As shown, the mounting component 11 is provided with a guide rail extending along the first direction, and the pushing mechanism 13, the second driving part 142, the cell clamp 141, the housing centering mechanism 12 and the housing positioning mechanism 16 are all provided with sliders. The relative position of each component along the first direction can be adjusted by moving the slider on the guide rail.

[0178] like Figure 1 and Figure 4 As shown, in some embodiments, the pushing mechanism 13 further includes a pushing mounting member 132 and a floating assembly 133. The pushing mounting member 132 is movably disposed on the mounting member 11, and a second through hole is provided on the pushing mounting member 132, through which the pushing rod 131 is movably disposed; the floating assembly 133 is floatingly connected to one end of the pushing rod 131 away from the first clamping part 1211.

[0179] The push mounting component 132 is movably disposed on the mounting component 11. Specifically, a guide rail extending along the first direction X can be provided on the mounting component 11, and a slider can be provided on the push mounting component 132. The movable connection between the push mounting component 132 and the mounting component 11 is realized by the movement of the slider on the guide rail.

[0180] The floating component 133 refers to a component that can float along the first direction X. By floatingly connecting the floating component 133 to the end of the push rod 131 that is away from the first clamping part 1211, when the resistance between the battery cell 2 and the housing 3 is too great, the push rod 131 can float in the first direction X, thereby avoiding the push rod 131 forcibly pushing the battery cell 2 and damaging the battery cell 2 when the resistance between the battery cell 2 and the housing 3 is too great.

[0181] like Figure 1 and4 As shown, in some embodiments, the floating component 133 is a first spring sleeved on the push rod 131, with one end of the first spring abutting against the push mounting member 132 and the other end abutting against the push rod 131.

[0182] The other end of the first spring abuts against the push rod 131. Specifically, in some embodiments, the other end of the first spring can be fixedly connected to the push rod 131. When the resistance between the battery cell 2 and the housing 3 is too high due to insufficient concentricity, the push rod 131 can compress the first spring and move in a direction away from the first direction X, preventing the push rod 131 from continuing to push the battery cell 2 into the housing 3. In other embodiments, a protrusion can be provided on the push rod 131, and the other end of the first spring abuts against the protrusion. When the resistance between the battery cell 2 and the housing 3 is too high due to insufficient concentricity, the push rod 131 can also compress the first spring and move in a direction away from the first direction X, preventing the push rod 131 from continuing to push the battery cell 2 into the housing 3 and damaging the battery cell 2.

[0183] like Figure 1 and Figure 4 As shown, in some embodiments, the push mounting member 132 is provided with a third through hole, and the floating assembly 133 includes a floating member 1331, a floating rod 1332, and a second spring 1333. The floating member 1331 is disposed on the side of the push rod 131 opposite to the first clamping portion 1211; one end of the floating rod 1332 is fixedly connected to the floating member 1331, and the floating rod 1332 passes through the third through hole along the first direction X; the second spring 1333 is sleeved on the floating rod 1332, and one end of the second spring 1333 abuts against the push mounting member 132, and the other end abuts against the floating rod 1332.

[0184] The floating component 1331 is disposed on the side of the push rod 131 away from the first clamping part 1211. Specifically, the floating component 1331 can be connected to the push rod 131 or spaced apart from the push rod 131. When the resistance between the battery cell 2 and the housing 3 is too large due to insufficient concentricity, the push rod 131 moves in a direction away from the first direction X, thereby lifting the floating component 1331, and thus realizing the floating of the push rod 131 along the first direction X, preventing the push rod 131 from continuing to push the battery cell 2 into the housing 3 and damaging the battery cell 2.

[0185] The other end of the second spring 1333 abuts against the floating rod 1332. Specifically, the other end of the second spring 1333 can be fixedly connected to the floating rod 1332; or a protrusion can be provided on the floating rod 1332, and the other end of the second spring 1333 abuts against the protrusion.

[0186] By setting up a floating component 1331, a floating rod 1332, and a second spring 1333, when the resistance between the battery cell 2 and the housing 3 is too high due to insufficient concentricity, the push rod 131 moves in a direction away from the first direction X. At this time, the floating component 1331 is pushed by the push rod 131 and compresses the second spring 1333, thereby realizing the floating component 1331, the floating rod 1332, and the push rod 131 floating in the first direction X, preventing the push rod 131 from continuing to push the battery cell 2 into the housing 3 and damaging the battery cell 2. In addition, compared with the solution of directly mounting the second spring 1333 on the push rod 131, this solution will not affect the shape and pushing function of the push rod 131, so there is no need to worry that the push rod 131 cannot install the floating component 133 due to size or shape limitations, or that the floating component 133 will interfere with the battery cell 2, the battery cell clamping mechanism 14, etc.

[0187] like Figure 16 and 17 As shown, this application also provides a casing insertion device for inserting a battery cell 2 into a casing 3. The casing insertion device includes a conveying mechanism 4 and a plurality of casing insertion devices 1. The mounting component 11 of the casing insertion device 1 is fixedly connected to the conveying mechanism 4 to convey the casing insertion device 1.

[0188] The conveying mechanism 4 can be a component that conveys along a straight line, such as a chain, belt, or conveyor belt, or it can be a component that conveys along a curve, such as a turntable or turret. This application does not limit this.

[0189] By setting up a conveying mechanism 4, multiple casing devices 1 can work simultaneously, thereby improving the efficiency of casing insertion of the battery cell 2.

[0190] like Figure 17 As shown, in some embodiments, the conveying mechanism 4 is a turret, and the casing device also includes a guide cam 5. The guide cam 5 is cylindrical and concentrically arranged with the turret. The guide cam 5 has three guide grooves 51 on its outer periphery. The three guide grooves 51 are respectively connected to the pushing mechanism 13, the second driving part 142 and the cell clamp 141 to drive the three to move along the first direction X.

[0191] By setting the guide cam 5, when the housing device 1 is conveyed in the turret, the guide groove 51 on the guide cam 5 can adjust the relative position of the push mechanism 13, the second drive part 142 and the cell clamp 141 along the first direction X, so that the assembly of the cell 2 and the housing 3 can be realized by an external power source, which is simple in structure and highly efficient.

[0192] like Figure 16 As shown, in some embodiments, the casing insertion device further includes a cell feeding device 6 and a casing feeding device 7, with different casing insertion devices 1 respectively provided to supply the cell 2 and the casing 3 to the casing insertion device 1.

[0193] The battery cell feeding device 6 and the housing feeding device 7 can be gripping mechanisms such as robotic arms, which can be used to grip and transport the battery cells to achieve feeding. Alternatively, the battery cell feeding device 6 and the housing feeding device 7 can be conveying mechanisms such as conveyor belts, which can directly transport the battery cells 2 and the housing 3 into the housing loading device 1.

[0194] By setting the cell feeding device 6 and the housing feeding device 7 to correspond to different housing insertion devices 1, the cell 2 feeding time and the housing 3 feeding time are distributed at different positions of the housing insertion equipment, which facilitates simultaneous feeding of both and improves the production efficiency of the housing insertion equipment.

[0195] like Figure 16 As shown, in some embodiments, the battery cell feeding device 6 includes a transition turntable 61, a feeding turntable 62, and a rejection turntable 63. The transition turntable 61 is correspondingly arranged with the turret; the feeding turntable 62 is correspondingly arranged with the transition turntable 61 to transport the battery cell 2 to the transition turntable 61; the rejection turntable 63 is arranged between the feeding turntable 62 and the turret along the rotation direction of the transition turntable 61 to reject unqualified battery cells 2.

[0196] Specifically, when the battery cell 2 is being fed, the battery cell 2 first arrives at the feeding turntable 62. The battery cell 2 is then transferred from the feeding turntable 62 to the transition turntable 61. On the transition turntable 61, the appearance and other quality of the battery cell 2 are inspected. When the battery cell 2 is qualified, it will enter the casing device 1 under the transfer of the transition turntable 61. When the battery cell 2 is unqualified, it will be transferred from the transition turntable 61 to the rejection turntable 63 to complete the rejection of unqualified products.

[0197] like Figure 16 As shown, in some embodiments, the cell feeding device 6 further includes a detection element 64 and a rejection mechanism 66. The detection element 64 is disposed between the feeding turntable 62 and the rejection turntable 63 for detecting the cell 2; the rejection mechanism 66 is disposed between the transition turntable 61 and the rejection turntable 63, and the rejection mechanism 66 can move towards the rejection turntable 63 to push the unqualified cell 2 detected by the detection element 65 from the transition turntable 61 to the rejection turntable 63.

[0198] like Figure 18 As shown, this application also provides a method for inserting a battery cell 2 into a housing 3, the method comprising:

[0199] S1: The battery cell is clamped and fixed by the battery cell clamping mechanism;

[0200] S2: The centering mechanism clamps and fixes the opening ends of the battery cell 2 and the housing 3 at both ends along the direction of gravity to ensure the concentricity of the battery cell 2 and the housing 3.

[0201] S3: The cell clamping mechanism and the centering mechanism move closer to each other along the direction of gravity to insert the cell 2 into the housing 3.

[0202] That is, the battery cell 2 and the housing 3 are first clamped and fixed in the centering mechanism along the direction of gravity to ensure their concentricity. Then the battery cell clamping mechanism and the centering mechanism move closer to each other, so that the battery cell 2 is inserted into the housing 3. During this insertion process, the opening of the housing 3 is always facing upward. That is, there is no need to flip or adjust the housing 3 before or after insertion, which can eliminate the flipping mechanism on the equipment, thereby simplifying the equipment structure and movement.

[0203] like Figure 18 As shown, in some embodiments, the shell insertion method further includes:

[0204] When the S4 cell clamping mechanism and the centering mechanism approach each other, the cell clamping mechanism reduces the clamping force on cell 2.

[0205] When the cell clamping mechanism and the centering mechanism approach each other, that is, when the cell 2 begins to be inserted into the housing 3, the cell clamping mechanism reduces the clamping force on the cell 2. In this way, on the one hand, the smaller clamping force can provide a certain frictional force for the cell 2 and the cell clamping mechanism, thereby ensuring that the cell 2 can be smoothly inserted into the housing 3; on the other hand, since the clamping force provided by the cell clamping mechanism is limited, when the cell 2 and the housing 3 encounter resistance when the cell 2 is inserted into the housing 3 due to insufficient concentricity or other reasons, the cell 2 cannot enter the housing due to insufficient clamping force and cannot generate enough frictional force between the cell 2 and the cell clamping mechanism (at this time, only the cell clamping mechanism and the cell 2 move relative to each other, but there is no relative movement between the cell 2 and the housing 3). In this way, it can prevent the cell 2 from being forcibly inserted into the housing 3 and damaging the cell 2 or the housing 3.

[0206] like Figure 18 As shown, in some embodiments, the shell insertion method further includes:

[0207] S5: When the cell clamping mechanism and the centering mechanism approach each other, the cell clamping mechanism releases the cell and stops the relative movement.

[0208] S6: The battery cell continues to be inserted into the housing under the push of the push mechanism until it is completely installed in the housing.

[0209] When the cell clamping mechanism and the centering mechanism approach each other, they stop moving relative to each other to avoid interference or even collisions caused by being too close. Subsequently, the pushing mechanism pushes the cell 2 into the housing 3, ensuring that the cell 2 is completely inside the housing 3.

[0210] Specifically, such as Figures 1 to 17As shown, during the feeding process, the battery cell 2 and the housing 3 are conveyed to the battery cell clamping mechanism 14 and the housing positioning mechanism 16 of the housing insertion device 1 via the battery cell feeding device 6 and the housing feeding device 7, respectively. At the same time, the detection component 64 on the battery cell feeding device 6 will inspect the appearance and other quality of the battery cell 2 and reject unqualified battery cells 2.

[0211] During insertion, the cell clamping mechanism 14 and the pushing mechanism 13, driven by the guide cam 5, approach the centering mechanism 12 along the first direction X, thereby placing the cell 2 into the first clamping part 1211. Simultaneously, the third driving part 165 lifts the housing 3 in the housing positioning mechanism 16 and places it into the second clamping part 1212, thus controlling the concentricity of the cell 2 and the housing 3. Subsequently, driven by the guide cam 5, the second driving part 142 pushes the cell clamping rotating seat 1412 to rotate relative to the cell clamping mounting part 1411, thereby reducing the clamping force of the cell clamping mechanism 14. At the same time, the distance between the cell clamping mechanism 14 and the centering mechanism 12 along the first direction X is further reduced, allowing the cell 2 to be inserted into the housing 3. Subsequently, the second drive unit 142 drives the cell clamp 141 to fully open, and the cell 2 is fully inserted into the housing 3 under the push of the push mechanism 13; at the same time, the centering mechanism 12 and the first drive unit 122 approach each other and push the centering rotating seat 1214 to rotate and open the centering clamp 121. The housing 3 gradually falls back into the housing positioning mechanism 16 under the push of the push mechanism 13.

[0212] After the battery is inserted into the shell, the shell 3 is unloaded by the unloading device. The pushing mechanism 13, the battery cell gripper 141 and the second drive unit 142 return to their initial positions under the drive of the guide cam 5. At the same time, the battery insertion device 1 returns to the battery cell loading position and the shell loading position under the conveying of the turret to carry out the next battery cell 2 insertion.

[0213] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0214] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
