And the sliced pole pieces enter the deviation correction station and the detection station before entering the lamination station for lamination operation. The deviation of the pole piece is corrected by the deviation correcting device at the deviation correcting station, and the image information of the notch edge of the pole piece is collected by the burr detecting device. And the collected image information is analyzed, so that whether burrs generated by cutting the pole piece exceed the standard or not can be judged. Therefore, due to the fact that the burr detection device is arranged between the deviation rectifying device and the lamination table, burr detection can be carried out on each pole piece laminated on the lamination table, and the pole pieces with burrs exceeding the standard are effectively prevented from flowing out.

Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery equipment, in particular to a cutting and stacking integrated machine. Background Art

[0002] The pole pieces required for the lamination process may produce burrs on the edges of the cuts, and the burrs on the edges of the pole pieces may pierce the diaphragm, causing the positive and negative poles to contact and cause a short circuit. In order to improve the product safety of lithium batteries, the pole pieces will be regularly inspected offline for burrs during the actual production process. When it is detected that the burrs on the pole pieces exceed the standard, shutdown measures will be taken and the relevant battery cells will be isolated for inspection. However, since factors such as molds, incoming materials, and the real-time status of equipment are all closely related to the generation of burrs, the generation of burrs is irregular. Therefore, the traditional sampling scheme still cannot eliminate the risk of pole pieces with excessive burrs flowing out. Utility Model Content

[0011] In one embodiment, it also includes:

[0014] A transport mechanism capable of transferring the electrode piece on the first conveying mechanism to the carrier at the loading station, and transferring the electrode piece on the carrier to the first conveying mechanism at the unloading station;

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0030] See also Figure 1 and Figure 2 The utility model provides a cutting and laminating machine 10. The cutting and laminating machine 10 includes a laminating table 100, a deviation correction device 200 and a burr detection device 300.

[0031] The stacking table 100 is arranged at the stacking station, the deflection correction device 200 is arranged at the deflection correction station, and the burr detection device 300 is arranged at the detection station. The cutting and stacking integrated machine 10 can drive the sliced ​​pole piece 20 to enter the deflection correction station and the detection station before entering the stacking station. Specifically, the pole piece 20 can be circulated between the stations under the drive of the conveyor belt and the manipulator. The pole piece 20 can enter the deflection correction station first, or it can enter the detection station first. The deflection correction device 200 can perform deflection correction operations on the pole piece 20 entering the deflection correction station, and the burr detection device 300 can collect image information of the cut edge of the pole piece 20 passing the detection station for burr detection. The pole piece 20 that passes the burr detection finally enters the stacking station and completes the stacking operation on the stacking table 100; the pole piece 20 that fails the burr detection is discarded.

[0032] It can be seen that since the burr detection device 300 is arranged between the correction device 200 and the stacking table 100, each pole piece 20 stacked on the stacking table 100 will be subjected to burr detection, thereby avoiding the missed detection of pole pieces 20 with excessive burrs, thereby effectively preventing the pole pieces 20 with excessive burrs from flowing out.

[0033] Specifically, the electrode sheet 20 includes a positive electrode sheet and a negative electrode sheet. Therefore, two deflection correction devices 200 and burr detection devices 300 are provided and are respectively located on both sides of the stacking platform 100, wherein the deflection correction device 200 and burr detection device 300 on one side are used for deflection correction and burr detection of the positive electrode sheet, and the deflection correction device 200 and burr detection device 300 on the other side are used for deflection correction and burr detection of the negative electrode sheet.

[0034] Moreover, the electrode sheets 20 on both sides can be transferred alternately to the stacking platform 100. In this way, the positive electrode sheets and the negative electrode sheets can be alternately stacked on the stacking platform 100 to produce a battery cell. Moreover, since the positive electrode sheets and the negative electrode sheets are independently transported, corrected, detected and transferred on different sides of the stacking platform 100, and are completed by different mechanisms, the positive electrode sheets and the negative electrode sheets can be effectively avoided from being mixed up.

[0035] Please refer again Figure 1 The cutting and stacking machine 10 in one embodiment of the present invention includes a stacking table 100, a deviation correction device 200 and a burr detection device 300. The burr detection device 300 includes a detection platform 310 and detection cameras 320 arranged on both sides of the detection platform 310 in the width direction.

[0036] The detection platform 310 is used to carry the electrode 20 entering the detection station. Specifically in this embodiment, the surface of the detection platform 310 can form a negative pressure to adsorb the carried electrode 20. The surface of the detection platform 310 is generally distributed with a plurality of adsorption holes (not shown) connected to the negative pressure cavity to form a negative pressure. Since the electrode 20 is adsorbed and fixed on the detection platform 310, it is possible to avoid the displacement of its position caused by factors such as airflow and vibration, thereby keeping the position of the electrode 20 stable for easy detection.

[0037] The detection platform 310 can expose the cut edges on both sides of the pole piece 20. Specifically, the cut of the pole piece 20 is located on both sides of its width direction, and the detection platform 310 is in a long strip shape and its width is slightly smaller than the width of the pole piece 20, so it can expose the cut edges on both sides of the pole piece 20. Since the cut edges are exposed, it is more convenient for the detection cameras 320 on both sides to respectively collect image information of the two cut edges of the pole piece 20 carried on the detection platform 310.

[0038] Furthermore, in the present embodiment, the burr detection device 300 includes a camera driving component 330 , and the detection camera 320 is disposed at a moving end of the camera driving component 330 , and can reciprocate along the longitudinal direction of the detection platform 310 under the drive of the camera driving component 330 .

[0039] The camera driving assembly 330 generally includes a guide rail and a driving element. The guide rail extends along the longitudinal direction of the detection platform 310. The driving element can be a cylinder, an electric cylinder, a linear motor or a motor screw pair structure. By driving the detection camera 320 to move along the longitudinal direction of the detection platform 310, the detection camera 320 can be focused on various places of the edge of the cut of the pole piece 20 in turn, thereby obtaining clearer image information.

[0040] In addition, in this embodiment, the deflection correction device 200 includes a deflection correction table 210, which is located on the side of the detection platform 310 facing away from the stacking station 100. The cutting and stacking machine 10 can drive the pole piece 20 to enter the deflection correction station, the detection station and the stacking station in sequence. The deflection correction table 210 can carry the pole piece 20 entering the deflection correction station and drive the carried pole piece 20 to perform the deflection correction operation.

[0041] Specifically, the deflection correction platform 210 can drive the pole piece 20 carried thereon to translate and rotate, thereby adjusting the position and angle of the pole piece 20. The deflection correction device 200 generally also includes a deflection correction camera (not shown), which is used to obtain image information of the pole piece 20 to determine whether the pole piece 20 is offset. The sliced ​​pole piece 20 is first placed on the deflection correction platform 210, and then transferred to the detection platform 310 after the deflection correction is completed.

[0042] In this embodiment, the cutting and stacking machine 10 also includes a first manipulator (not shown), a second manipulator (not shown) and a third manipulator (not shown). The first manipulator can grab the pole piece 20 and place it on the correction table 210, the second manipulator can grab the pole piece 20 on the correction table 210 and place it on the detection platform 310, and the third manipulator can grab the pole piece 20 on the detection platform 310 and place it on the stacking table 100.

[0043] The first manipulator, the second manipulator and the third manipulator can all adopt the same structure and can grasp the pole piece 20 through the suction cup.

[0044] Please refer again Figure 2 In another embodiment of the present invention, a cutting and stacking machine 10 includes a stacking table 100, a deviation correction device 200, a burr detection device 300, a first conveying mechanism 400, a second conveying mechanism 500 and a transport mechanism 600.

[0045] The first conveying mechanism 400 can carry and convey the electrode piece 20 to the deflection correction station. The sliced ​​electrode piece 20 is placed on the first conveying mechanism 400 and conveyed downstream by the first conveying mechanism 400. Specifically in this embodiment, the first conveying mechanism 400 is configured as a vacuum belt. In this way, the electrode piece 20 can be adsorbed on the surface of the vacuum belt during the conveying process, thereby preventing the electrode piece 20 from falling off.

[0046] The second conveying mechanism 500 includes a plurality of carrier plates 510, each of which can move along a circular path and pass through a loading station, a testing station, and a unloading station in sequence. Specifically, the second conveying mechanism 500 can be provided with a circular guide rail (not shown). The plurality of carrier plates 510 can be slidably mounted on the guide rail. A driving element can be provided on each carrier plate 510 to drive each carrier plate 510 to slide along the guide rail individually, so as to pass through a loading station, a testing station, and an unloading station in sequence.

[0047] Specifically, in this embodiment, the second conveying mechanism 500 further includes a magnetic suspension track (not shown), and a plurality of carriers 510 are disposed on the magnetic suspension track and can circulate along the magnetic suspension track between the loading station, the inspection station, the unloading station and the loading station. The magnetic suspension track does not directly contact the carrier 510, so the friction force on the carrier 510 is extremely small, which helps to maintain a stable state.

[0048] The carrier plate 510 is used to carry the electrode 20 and is generally in a long strip shape. Further, the unloading station is located downstream of the first conveying mechanism 400 in the conveying direction relative to the loading station. Figure 2 As shown in the example, if the first conveying mechanism 400 conveys from left to right, the unloading station is located on the right side of the loading station.

[0049] The transport mechanism 600 can be a manipulator or a manipulator with a suction cup, which can pick up and release the electrode piece 20. The transport mechanism 600 can transfer the electrode piece 20 on the first conveying mechanism 400 to the carrier 510 at the loading station, and can transfer the electrode piece 20 on the carrier 510 to the first conveying mechanism 400 at the unloading station. Specifically, in the present embodiment, two transport mechanisms 600 are provided, one of which is responsible for transferring the electrode piece 20 on the first conveying mechanism 400 to the carrier 510 at the loading station, and the other transport mechanism 600 is responsible for transferring the electrode piece 20 on the carrier 510 to the first conveying mechanism 400 at the unloading station.

[0050] More specifically, the burr detection device 300 in this embodiment includes two sets of detection cameras 320 arranged opposite to each other, and the pole piece 20 passing through the detection station passes between the two sets of detection cameras 320, and the two sets of detection cameras 320 can respectively collect image information of the two cut edges of the pole piece 20. Each set of detection cameras 320 may include more than two detection cameras 320, and the detection cameras 320 in this embodiment may adopt the same structure as the detection cameras 320 in the previous embodiment.

[0051] Since the pole piece 20 in this embodiment is carried on the carrier plate 510 when passing through the inspection station, and the inspection camera 32 for taking pictures can be fixedly arranged, the burr inspection device 300 can omit the inspection platform 310 and the camera driving component 330 compared with the previous embodiment.

[0052] During the operation of the cutting and stacking machine 10, the sliced ​​electrode 20 is first placed on the first conveying mechanism 400 and transported to the deflection correction station by the first conveying mechanism 400 to prepare for deflection correction and lamination operations. When the electrode 20 enters the loading station, the transport mechanism 600 transfers the electrode 20 on the first conveying mechanism 400 to the carrier 510, and then the carrier 510 carries the electrode 20 into the inspection station, and the two opposite sets of inspection cameras 320 collect image information of the electrode 20 to realize burr detection. If the burrs of the electrode 20 after the inspection are qualified, it will continue to move to the unloading station with the carrier 510, and be sent back to the first conveying mechanism 400 by the transport mechanism 600 to continue to be transported to the deflection correction station.

[0053] Different from the previous embodiment, the pole piece 20 in this embodiment enters the inspection station before entering the deflection correction station. After the pole piece that has passed the burr detection is transported to the deflection correction station, the deflection correction device 200 can perform deflection correction operations on it. Specifically, the deflection correction device 200 in this embodiment can adopt the same structure as that in the previous embodiment. After the deflection correction is completed, the pole piece 20 can be transferred from the deflection correction station to the lamination table 100 for lamination by the lamination robot.

[0054] By controlling the speed of the first conveying mechanism 400 and the second conveying mechanism 500, when the carrier 510 moves from the loading station to the unloading station, the empty space formed by the electrode 20 moving out of the first conveying mechanism 400 is also transferred from the loading station to the unloading station. In this way, the transport mechanism 600 can return the electrode 20 that has completed the inspection to its original position on the first conveying mechanism 400. In this process, the first conveying mechanism 400 does not need to be stopped, so the electrode 20 can be inspected online, which helps to improve the overall working efficiency of the cutting and stacking machine 10.

[0055] In this embodiment, a pre-positioning station is provided between the loading station and the detection station, and the pre-positioning station is provided with a pre-positioning mechanism 700, which can perform a correction operation on the pole piece 20 passing through the pre-positioning station. The pole piece 20 may be offset during the conveying process of the first conveying mechanism 400 and the second conveying mechanism 500, thereby affecting the detection effect of the burr detection device 300. By correcting the deviation through the pre-positioning mechanism 700, the position of the pole piece 20 passing through the detection station can be kept consistent, thereby ensuring the accuracy of the burr detection result.

[0056] Specifically, the pre-positioning mechanism 700 in this embodiment may include a correction camera and a robot for correction, and the robot can move according to the carrier 510 to correct the pole piece 20 carried by it. In this embodiment, the transport mechanism 600 can transfer multiple pole pieces 20 carried on the first conveying mechanism 400 to multiple carriers 510 respectively, or transfer multiple pole pieces 20 carried on multiple carriers 510 respectively to the first conveying mechanism 400 during a transport operation.

[0057] For example, after the electrode pieces 20 are transported to the loading station, the transport mechanism 600 can simultaneously transfer the four electrode pieces 20 to the four carriers 510. When the four carriers 510 carrying the electrode pieces 20 complete the deflection correction and burr detection and flow to the unloading station, the transport mechanism 600 can simultaneously transfer the four electrode pieces 20 on the four carriers 510 to the first transport mechanism 400. In this way, the number of actions of the transport mechanism 600 can be reduced, which helps to further improve work efficiency.

[0058] In addition, in this embodiment, the pole pieces 20 on the first conveying mechanism 400 are perpendicular to the conveying direction of the first conveying mechanism 400. For example, if the first conveying mechanism 400 is conveyed in the left-right direction, the pole pieces 20 extend in the up-down direction on the first conveyor 400. In this way, each pole piece 20 occupies a smaller lateral (conveying direction) space on the first conveying mechanism 400, and the first conveying mechanism 400 can convey more pole pieces 20 per unit time, thereby helping to improve the conveying efficiency of the pole pieces 20.

[0059] Furthermore, each carrier plate 510 in this embodiment can rotate around a rotation axis, and the carrier plate 510 can rotate to be perpendicular to the conveying direction of the first conveying mechanism 400 when entering the loading station and the unloading station, and can rotate to be parallel to the conveying direction of the first conveying mechanism 400 when entering the deviation correction station and the detection station.

[0060] The carrier plate 510 may be provided with a rotating shaft (not shown) perpendicular to its bearing surface to achieve rotation. When the carrier plate 510 is rotated to be perpendicular to the conveying direction of the first conveying mechanism 400, its extension direction is the same as the extension direction of the electrode 20 on the first conveying mechanism 400, so that the handling mechanism 600 can transfer the electrode 20 between the first conveying mechanism 400 and the second conveying mechanism 500.

[0061] When the carrier plate 510 rotates to be parallel to the conveying direction of the first conveying mechanism 400, the electrode piece 20 carried by it is rotated approximately 90 degrees compared to when it is on the first conveying mechanism 400. At this time, the two cut edges of the electrode piece 20 can face the two sets of detection cameras 320 respectively, so that it is more convenient for the detection camera 320 to obtain image information of the cut edges.

[0062] The above-mentioned cutting and stacking machine 10, the sliced ​​pole piece 20 will enter the correction station and the detection station in sequence before entering the stacking station for stacking operation. The pole piece is corrected by the correction device 200 at the correction station, and the image information of its cut edge is collected by the burr detection device 300. By analyzing the collected image information, it can be determined whether the burrs generated by the cutting of the pole piece 20 exceed the standard. It can be seen that since the burr detection device 300 is arranged between the correction device 200 and the stacking table 100, each pole piece 20 stacked on the stacking table 100 will be subjected to burr detection, thereby effectively preventing the pole piece 20 with excessive burrs from flowing out.

[0063] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0064] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
