Detailed Implementation

[0042] The technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0043] The components of the embodiments of this application described and shown in the accompanying drawings can be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of this application provided in the drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application.

[0044] Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0045] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0046] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0047] The following reference Figures 1 to 10 This application describes a floating positioning and automatic correction device according to some embodiments.

[0048] See Figures 1 to 8 As shown, an embodiment of this application provides a floating positioning and automatic correction device, including: a support member 1, a floating member 2 disposed on the support member 1, and a first positioning mechanism 5;

[0049] The floating component 2 is disposed on the supporting component 1 and can slide relative to the supporting component 1;

[0050] The first positioning mechanism 5 is disposed on the side of the floating member 2, and the first positioning mechanism 5 is used to position the workpiece placed on the floating member 2. During the positioning process, the workpiece placed on the floating member 2 remains relatively stationary with respect to the floating member 2 (in this embodiment, the workpiece is the battery cell 7, and this will be used as an example for the following description. Of course, the workpiece is not limited to the battery cell 7, but can also be other structures).

[0051] Based on the structure described above, when positioning the battery cell 7 using the novel floating positioning and automatic alignment device provided in this application, the robot first places the battery cell 7 onto the floating component 2. The floating component 2 and the battery cell 7 on it are in a free state. Then, the first positioning mechanism 5 pushes the battery cell 7 and moves synchronously with the floating component 2, ultimately making the battery cell 7 accurately positioned. During the positioning process, the battery cell 7 and the floating component 2 are always in a relatively stationary state, that is, there is no relative movement between them. This avoids damage to the electrode and separator of the battery cell 7 and helps to reduce the defect rate of the battery cell 7. In addition, the battery cell 7 can be accurately positioned before the next process, which can improve the accuracy of the next process, such as the stacking of the battery cell 7.

[0052] Preferably, such as Figure 1 As shown, the floating positioning and automatic correction device also includes an auxiliary rolling member 3, which is disposed on the support member 1. The floating member 2 is placed on the top of the auxiliary rolling member 3 along its height direction, so that rolling friction is formed between the floating member 2 and the support member 1.

[0053] Furthermore, preferably, the auxiliary rolling member 3 includes a mounting base and a ball disposed in the mounting base, and the ball is capable of rolling relative to the mounting base; the floating member 2 is placed on the ball.

[0054] Based on the above structure, it can be seen that placing the floating component 2 above the ball causes rolling friction between the floating component 2 and the supporting component 1. The rolling friction is very small, ensuring that both can maintain a relatively stationary state and move synchronously, thus avoiding damage to the battery cell 7.

[0055] Based on the aforementioned structure, the auxiliary rolling member 3 can preferably be a bullseye bearing, which meets the usage requirements, is easy to procure, and has low cost. Of course, the structure of the auxiliary rolling member 3 is not limited to this; it can also be other structures that enable the floating member 2 and the supporting member 1 to form rolling friction. Preferably, the supporting member 1 is a rectangular plate, and the floating member 2 is also a rectangular plate, and it is disposed above the supporting member 1.

[0056] Preferably, such as Figure 1 As shown, multiple auxiliary rolling members 3 are provided on both sides of the support member 1 along its width direction, and the multiple auxiliary rolling members 3 on each side are arranged sequentially at intervals along the length direction of the support member 1.

[0057] In this embodiment, preferably, as follows: Figures 1 to 3 As shown, the floating positioning and automatic correction device also includes a correction mechanism 4 disposed on the support member 1, which is used to adjust the floating member 2 to a preset feeding position.

[0058] Further, preferably, such as Figures 1 to 3 As shown, there are two correction mechanisms 4, which are respectively located at both ends of the floating member 2 along its corrected length direction.

[0059] Furthermore, preferably, the floating member 2 is provided with a clearance groove 21, and preferably, the clearance groove 21 is provided on both the left and right sides of the floating member 2, and the clearance groove 21 passes through the corresponding side of the floating member 2.

[0060] As can be seen from the structure described above, before feeding the battery cell 7, the position of the floating component 2 is adjusted by the two correction mechanisms 4 at both ends of the floating component 2 so that it is corrected to the feeding position, and then the battery cell 7 is fed into the floating component 2. This not only facilitates effective cooperation with the robot arm on the preset route, but also effectively avoids the gripper of the robot arm on the preset route through the avoidance groove 21 at the preset position.

[0061] Of course, the number of corrective mechanisms 4 is not limited to this. There can be two or one, for example, when the other end of the floating member 2 has a fixed object as a corrective structure, it only needs to set one corrective mechanism 4 at one end. Or when the floating member 2 is a multi-deformable or irregular structure, it can set corrective mechanisms 4 at multiple ends, depending on actual needs.

[0062] In this embodiment, preferably, as follows: Figure 3 As shown, the correction mechanism 4 includes three correction drive devices 41, two of which are respectively disposed on opposite sides of the floating member 2 and each has a telescopic end facing the floating member 2.

[0063] One of the correction drive devices 41 is located at the end of the floating member 2 and has a telescopic end facing the floating member 2.

[0064] As can be seen from the structure described above, the drive ends of the three alignment drive devices 41 all extend, pushing the floating component 2 to be aligned, that is, to be in the preset material feeding position.

[0065] Furthermore, preferably, the correction drive device 41 is a cylinder.

[0066] Furthermore, preferably, the support member 1 has a mounting groove 22 at its bottom along its height direction, and the side of the mounting groove 22 has an opening, through which the correction drive device 41 is installed in the corresponding mounting groove 22.

[0067] Of course, the number of correction drive devices 41 is not limited to three, but can also be four, five, six, etc. For example, two or three correction drive devices 41 can be provided on each side of the floating member 2 along the width direction. Two or three can be provided at one end of the floating member 2 along its corrected length direction. Of course, when the end of the floating member 2 is polygonal, correction drive devices 41 can also be provided on multiple side parts, depending on the actual needs.

[0068] In this embodiment, preferably, as follows: Figures 1 to 8 As shown, the first positioning mechanism 5 includes a first positioning component 51, and each first positioning component 51 includes a first driving device 511, a first pushing member 512, and a first blocking and limiting member 514; wherein, the first driving device 511 is disposed on the support member 1;

[0069] The first blocking and limiting member 514 is disposed on the side of the floating member 2, and the first blocking and limiting member 514 is connected to the first driving device 511 through the first pushing member 512. The first driving device 511 is used to drive the first blocking and limiting member 514 to move relative to the floating member 2.

[0070] Further, preferably, such as Figures 1 to 3 as well as Figure 7 As shown, there are multiple first blocking and limiting members 514, which are arranged sequentially along the length of the floating member 2. The first positioning component 51 also includes a first connecting member 513, and the multiple first blocking and limiting members 514 are all connected to the first pushing member 512 through the first connecting member 513. It can be seen that the first connecting member 513 can realize the synchronous linkage of multiple first blocking and limiting members 522, improve the positioning effect, and reduce the number of driving devices, which helps to reduce costs.

[0071] Further, preferably, such as Figures 1 to 3 As shown, the first positioning mechanism 5 includes a second positioning component 52 (which is disposed on the outside of the first positioning component away from the floating component 2), and the second positioning component 52 includes an auxiliary mounting component 521 and a limiting component 522; wherein, the auxiliary mounting component 521 is disposed on the support component 1, the limiting component 522 is connected to the auxiliary mounting component 521, and the limiting component 522 extends to one end of the floating component 2 along its corrected length direction.

[0072] And preferably, such as Figures 1 to 8 As shown, there are two first positioning components 51, which are respectively disposed on both sides of the floating member 2 along its corrected width direction; there are two second positioning components 52, which are respectively disposed on both ends of the floating member 2 along its corrected length direction. That is to say, this application adopts a structure of one side reference and three sides positioning. Along the length direction of the battery cell 7, one end of the battery cell 7 is provided with a second positioning component 52. This second positioning component 52 serves as a reference and remains stationary. It does not need to be equipped with the second driving device 523 described below. The other end of the battery cell 7 is also provided with a second positioning component 52. However, this second positioning component 52 needs to be equipped with a second driving device 523. Preferably, the second driving device 523 is disposed on the support member 1, and the corresponding auxiliary mounting member 521 is connected to the second driving device 523. The second driving device 523 is used to drive the limiting member 522 to approach or move away from the battery cell 7 placed on the floating member 2. In addition, the two sides of the battery cell 7 along its width direction are positioned by two first positioning components 51.

[0073] Of course, it is not limited to this. Four-sided simultaneous driving positioning can also be used, that is, the two ends of the battery cell 7 along its length direction are provided with a second positioning component 52, and each second positioning component 52 includes a second driving device 523. This can also meet the positioning requirements, but more components are used, which increases the cost.

[0074] As can be seen from the structure described above, after the floating component 2 is aligned using the alignment mechanism 4, the robot places the primary battery cell onto the floating component 2. The drive end of the alignment drive device 41 of the alignment mechanism 4 retracts completely, and the floating component 2 and the battery cell 7 on the floating component 2 are supported by the bullseye bearing at the bottom, so that the floating component 2 and the battery cell 7 on it are in a free state. Then, the drive end of the first drive device 511 retracts, causing the first blocking and limiting member 514 to move toward the battery cell 7. All the first blocking and limiting members 514 on both sides of the battery cell 7 abut against the side of the battery cell 7 according to the aforementioned operation, thereby achieving the limitation of the battery cell 7 on both sides along its width direction. At the same time, the drive end of the second drive device 523 retracts, causing the limiting member 522 to move toward the battery cell 7 and push the battery cell 7 against the limiting member 522 at the other end, thereby achieving the limitation of the battery cell 7 at both ends along its length direction.

[0075] As can be seen, for the rectangular battery cell 7, both ends in the length direction and both sides in the width direction are effectively limited. Then, the secondary battery cell can be placed on the primary battery cell through the second positioning mechanism 6, or it can be directly picked up by the robot and transferred to the next process (when the robot picks up the battery cell 7, after the robot has stably picked up the battery cell 7, the first positioning component 51 and the second positioning component 52 need to be activated to release the battery cell 7, so that the robot can take the battery cell 7 away).

[0076] Preferably, both the first drive device 511 and the second drive device 523 are cylinders. However, other options are possible depending on actual needs, such as a motor and lead screw or gear / rack transmission structure. Furthermore, preferably, there are two of each of the first drive device 511 and the second drive device 523, but this is not limited to two; more than two may be used. Preferably, such as... Figure 6 As shown, the first pushing member 512 includes a square plate and an L-shaped support block connected to each other. An extension of the L-shaped support block extends to the bottom of the first connecting member 513 and is connected to the first connecting member 513.

[0077] Preferably, such as Figure 7As shown, the first blocking and limiting member 514 includes a first supporting part 5141 and a first blocking and limiting part 5142; wherein, the first blocking and limiting part 5142 has an oblong hole along the width direction of the floating member 2, and the first blocking and limiting part 5142 and the first supporting part 5141 are assembled by bolts and oblong holes, so that the longitudinal position of the first blocking and limiting part 5142 can be adjusted along the width direction of the floating member 2; the first connecting member 513 has an oblong hole extending along the length direction of the floating member 2, and the first blocking and limiting member 514 and the first connecting member 513 are detachably connected by an assembly structure of bolts and oblong holes, so that the lateral position of the first blocking and limiting member 514 can be adjusted along the length direction of the floating member 2.

[0078] Based on this, preferably, the first blocking and limiting part 5142 is a cuboid extending along the width direction of the floating member 2; the first supporting part 5141 is a cuboid.

[0079] Preferably, such as Figures 1 to 3 As shown in Figure 7, the first adapter 513 is a cuboid extending along the length of the floating member 2, and the top corners of the ends of this cuboid are rounded. An oblong through hole extending along the length of the cuboid is provided on the cuboid.

[0080] Preferably, such as Figure 2 As shown, the auxiliary installation component 521 includes a first plate 5211 arranged in the vertical direction and a second plate 5212 arranged in the horizontal direction, and the two are connected together. The first plate 5211 is connected to the second driving device 523, and the second plate 5212 is connected to the limiting component 522.

[0081] Preferably, such as Figure 2 As shown, the limiting member 522 includes a limiting plate and two limiting posts. The limiting plate has a groove on the side facing the floating member 2 to avoid the protrusion structure at the front end of the battery cell 7. The two limiting posts are respectively set on both sides of the groove and can abut against both sides of the protrusion structure of the battery cell 7 to play a limiting role. The limiting plate and the aforementioned second plate 5212 are connected together by a plug-in protrusion and a slot. Of course, it is not limited to this. The two can be connected by bolts or welding.

[0082] In this embodiment, preferably, as follows: Figures 1 to 8 As shown, the floating positioning and automatic correction device also includes a second positioning mechanism 6, which is used to limit the placement path of the secondary battery cell placed on the primary battery cell, so that the secondary battery cell is placed directly above the primary battery cell.

[0083] Further, preferably, such as Figures 1 to 8As shown, the second positioning mechanism 6 includes a third driving device 61, a second pushing member 62, and a second blocking and limiting member 63; wherein, the third driving device 61 is disposed on the supporting member 1, and preferably, the third driving device 61 is a cylinder. Of course, it can also be selected according to actual needs, such as a transmission structure of motor and lead screw or gear and rack.

[0084] The second blocking and limiting member 63 is disposed on the side of the floating member 2, and the second blocking and limiting member 63 is connected to the third driving device 61 through the second pushing member 62. The third driving device 61 is used to drive the second blocking and limiting member 63 to move relative to the floating member 2.

[0085] Furthermore, preferably, there are two second positioning mechanisms 6, which are respectively disposed on both sides of the floating member 2 along its corrected width direction.

[0086] As can be seen from the structure described above, for a rectangular primary battery cell, after its two ends in the length direction and both sides in the width direction are positioned by the first positioning mechanism 5, the driving end of the third driving device 61 retracts, causing the second blocking and limiting member 63 to move toward the battery cell 7, so that the guide side of the second blocking and limiting member 63 is above the edge of the battery cell 7, that is, a guide passage is formed above the battery cell 7. The robot places the secondary battery cell above the second blocking and limiting member 63 and performs forward placement through the aforementioned guide passage, allowing the secondary battery cell to slide freely along the guide side of the second blocking and limiting member 63 to fall directly above the primary battery cell, achieving the automatic alignment function of the battery cell 7. This avoids friction between the battery cells 7, ensures accurate stacking, and is efficient and practical.

[0087] In this embodiment, preferably, as follows: Figures 1 to 3 As shown in Figure 7, there are multiple second blocking and limiting members 63, which are arranged sequentially along the length direction of the floating member 2; there are also multiple second pushing members 62, which correspond one-to-one with the multiple second blocking and limiting members 63.

[0088] The second positioning mechanism 6 also includes a second transition member 64, through which a plurality of second pushing members 62 are connected.

[0089] As can be seen from the structure described above, the second adapter 64 enables the synchronous linkage of multiple second stop and limit components 63, improving the positioning effect. In addition, reducing the number of drive devices helps to reduce costs.

[0090] Preferably, such as Figure 7 As shown, the second transition member 64 is a cuboid extending along the length of the floating member 2, and its top is provided with an avoidance groove to avoid the first pushing member 512.

[0091] Preferably, such as Figure 6 As shown, the second pushing member 62 includes a first mounting plate 621, a second mounting plate 622, and a third mounting plate 623 that are connected vertically in sequence to form a C-shaped structure. The first connecting member 513 is disposed within the C-shaped structure and is connected to the first mounting plate 621. The second mounting plate 622 is disposed on the side of the supporting member 1. The second blocking and limiting member 63 is connected to the third mounting plate 623. The third mounting plate 623 extends above the supporting member 1 and is located on the side of the floating member 2.

[0092] Preferably, such as Figure 7 As shown, the second blocking and limiting member 63 includes a second support part 631 and a second blocking and limiting part 632; wherein, the second blocking and limiting part 632 has an oblong hole along the width direction of the floating member 2, and the second blocking and limiting part 632 and the second support part 631 are assembled by bolts and the oblong hole, so that the longitudinal position of the second blocking and limiting part 632 can be adjusted along the width direction of the floating member 2; the third mounting plate 623 of the second pushing member 62 has an oblong hole extending along the length direction of the floating member 2, and the second blocking and limiting member 63 and the second pushing member 62 are assembled by bolts and the oblong hole, so that the lateral position of the second blocking and limiting part 632 can be adjusted along the length direction of the floating member 2.

[0093] Based on this, preferably, the second blocking and limiting part 632 is a cuboid extending along the width direction of the floating member 2; the second support part 631 is a cuboid.

[0094] In summary, the working principle of the floating positioning and automatic correction device provided in this application is as follows:

[0095] Step 1: First, extend all the drive ends of the three alignment drive devices 41 to push the floating component 2 to be aligned, that is, to be in the preset material feeding position.

[0096] Step 2: Using a robotic arm, the primary battery cell is placed onto the floating component 2. The driving end of the correction drive device 41 of the correction mechanism 4 retracts completely, and the floating component 2 and the battery cell 7 on the floating component 2 are supported by the bullseye bearing at the bottom, so that the floating component 2 and the battery cell 7 on it are in a free state. Then, the driving end of the first drive device 511 retracts, causing the first blocking and limiting component 514 to move toward the battery cell 7. All the first blocking and limiting components 514 on both sides of the battery cell 7 abut against the side of the battery cell 7 according to the aforementioned operation, thereby achieving the limitation of the battery cell 7 on both sides along its width direction. At the same time, the driving end of the second drive device 523 retracts, causing the limiting component 522 to move toward the battery cell 7 and push the battery cell 7 against the limiting component 522 at the other end, thereby achieving the limitation of the battery cell 7 at both ends along its length direction.

[0097] Step 3: When it is necessary to stack another cell 7 on the primary cell 7 on the floating component 2, the drive end of the third drive device 61 is retracted, causing the second blocking and limiting component 63 to move toward the cell 7, so that the guide side of the second blocking and limiting component 63 is above the edge of the cell 7, that is, a guide passage is formed above the cell 7. The robot places the secondary cell above the second blocking and limiting component 63 and performs forward placement through the aforementioned guide passage, so that the secondary cell slides down along the guide side of the second blocking and limiting component 63 and falls directly above the primary cell, completing the accurate stacking of the two cells 7.

[0098] Step four: Finally, the robotic arm will simultaneously pick up the two stacked battery cells 7 and move them to the next workstation.

[0099] Note: In actual production, two floating positioning and automatic correction devices can be used to position the two battery cells 7 (i.e., the primary battery cell and the secondary battery cell) separately in the manner described above. After positioning is completed, the robot arm picks up the positioned secondary battery cell and places it on the primary battery cell. Of course, the secondary battery cell placed can also be a battery cell 7 that has not been positioned by the floating positioning and automatic correction devices, or it can be a battery cell 7 that has been positioned by other structures.

[0100] In addition, after step two is completed, steps three and four can be skipped. Instead, the robotic arm can directly transfer the positioned battery cell 7 to other processes, depending on actual needs.

[0101] As can be seen from the above, the floating positioning design for placing the battery cell 7 in this technical solution can effectively avoid damage to the electrode or separator of the battery cell 7 due to external squeezing or pushing. In addition, the second battery cell 7 is stacked and placed through a guide structure, falling freely on the first battery cell 7, which plays an automatic alignment function of the battery cell 7. This not only avoids friction between the battery cells 7, but also ensures accurate stacking, high efficiency and practicality, and reduces production costs and subsequent maintenance costs.

[0102] Note: In this embodiment, if the structure is arranged based on the length and width of the floating member 2, it is arranged according to the orientation of the floating member 2 after it has been corrected by the correction mechanism 4, rather than in a skewed state.

[0103] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them.
