[0045] The battery pack alignment device and battery processing equipment provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0046] Reference Figures 1 to 3 As shown, Figure 1 A schematic diagram of a battery pack calibration device according to an embodiment of this application is shown. Figure 2 A top view of the battery pack alignment device according to an embodiment of this application is shown. Figure 3 A side view of a battery pack film correction device according to an embodiment of this application is shown.

[0047] According to some embodiments of this application, a battery pack alignment device is used for processing a battery 600. The battery 600 includes a battery body 610 and a film layer 620 covering the surface of the battery body 610. The film layer 620 has two extending edges 621, which at least partially overlap. The battery pack alignment device includes: a base 100, a transfer assembly 200, a support assembly 300, and an alignment assembly 400. The transfer assembly 200 is movably connected to the base 100 and is used to transfer and fix the battery 600. The support assembly 300 is mounted on the base 100 and has a clearance opening 301. The support assembly 300 is used to support one side of the extending edge 621, and the clearance opening 301 corresponds to the overlapping portion of the extending edge 621. The alignment assembly 400 is movably connected to the base 100 and is used to move from the other side of the extending edge 621 toward the extending edge 621 and push the two extending edges 621 at least partially separate to align the position of the film layer 620.

[0048] In the embodiments of this application, a transfer component 200 is provided on the base 100 to transfer the battery 600 to a preset position. The battery is then supported on one side of the two extended edges 621 of the film layer 620 by a support component 300, with the clearance opening 301 in the support component 300 corresponding to the overlapping portion of the two extended edges 621. Furthermore, by controlling the correction component 400 to move from the other side of the two extended edges 621 toward the extended edges 621, the two extended edges 621 are at least partially separated. This achieves positional correction of the overlapping portion of the two extended edges 621, preventing misalignment at the overlapping point of the two extended edges 621 of the film layer 620, which could lead to wrinkles, bubbles, and other problems after battery coating. This helps improve the coating quality of the battery 600.

[0049] Understandably, in the battery 600 manufacturing process, it is typically necessary to cover the four sides of the battery body 610 with a film layer 620 to provide insulation protection. The battery body 610 usually includes two large, opposing surfaces and four side surfaces. During the coating process of the battery 600, one or two film layers 620 are usually used. First, the two large surfaces of the battery body 610 are covered, and the edges of the film layer 620 extend outwards with extension edges 621. After the large surfaces of the battery body 610 are covered, the extension edges 621 of the film layer 620 are folded over to cover the sides of the battery body 610.

[0050] like Figure 6 As shown, Figure 6A schematic diagram of a battery according to an embodiment of this application is shown. The first extension edge 621a of the film layer 620 is folded down from top to bottom, and the second extension edge 621b is folded up from bottom to top. The first extension edge 621a and the second extension edge 621b overlap at least partially. When the first extension edge 621a and the second extension edge 621b are used to cover the corresponding sides of the battery body 610, parts of the first extension edge 621a and the second extension edge 621b will be suspended. These parts of the extension edge 621 are prone to defects such as misalignment and bulging. If these parts of the extension edge 621 are directly pressed to the battery body 610, it will cause quality defects such as wrinkles and bubbles in the corresponding area of ​​the film layer 620 on the battery body 610.

[0051] Therefore, this application provides a battery pack alignment device that can be applied to the battery packing process of battery 600. After completing the large-scale coating operation of the battery body 610 and folding the extension edge 621 of the film layer 620, the device further aligns the overlapping positions of the two sides of the extension edge 621 of the film layer 620, thereby reducing defects such as misalignment and bulging of the extension edge 621 and effectively reducing the defect rate of battery 600.

[0052] Specifically, a movable transfer component 200 is provided on the base 100. A preset position can be set on the base 100 for performing calibration operations. The transfer component 200 can be used to transfer the battery 600 from the previous process to the preset position and clamp and fix the battery 600.

[0053] like Figure 7 As shown, Figure 7 The diagram shows a schematic of the battery pack alignment device before alignment begins according to an embodiment of this application. At this time, the two large surfaces of the battery body 610 are covered with film layers 620, and the extension edges 621 of the upper and lower film layers 620 are folded over and cover the sides of the battery body 610, with the two extension edges 621 at least partially overlapping.

[0054] Furthermore, a support assembly 300 and a correction assembly 400 are provided on the base 100. The support assembly 300 supports one side of the two extension edges 621. The support assembly 300 has a clearance opening 301, which corresponds to the overlapping portion of the two extension edges 621 when the support assembly 300 supports the extension edges 621. The correction assembly 400 pushes the extension edges 621 from the other side, causing the overlapping portion of the two extension edges 621 to separate from each other, thereby correcting the relative position of the two extension edges 621 and eliminating problems such as misalignment and bulging of the two extension edges 621.

[0055] It is understandable that, such as Figure 6As shown, the extension edge 621 may include a first side and a second side opposite to each other. The first side faces the battery body 610, and the second side faces away from the first side. Typically, the first side of the extension edge 621 is provided with an adhesive layer so as to bond and fix it to the battery body 610.

[0056] A support component 300 can be provided to support the first side of the extension edge 621. The correction component 400 can at least partially move along the direction from the second side of the extension edge 621 to the first side. During the correction operation, the correction component 400 abuts against the second side of the extension edge 621 and applies a pushing force to the two extension edges 621 to separate the overlapping portions of the two extension edges 621. In this way, when the correction component 400 is reset, it can prevent the correction component 400 from sticking to the extension edge 621.

[0057] Optionally, such as Figure 1 As shown, the support assembly 300 includes a first driving member 310 and a support member 320; the first driving member 310 is mounted on the base 100, the support member 320 is connected to the first driving member 310, and a clearance opening 301 is provided in the support member 320. The first driving member 310 is used to drive the support member 320 closer to the battery 600, and is supported on one side of the two extended edges 621 by the support member 320.

[0058] In the embodiments of this application, the support member 320 can be driven to reciprocate by the first driving member 310. The support member 320 is provided with a clearance opening 301. During the correction operation, the first driving member 310 drives the support member 320 to move closer to the battery body 610, and the support member 320 extends at least partially to one side of the two extension edges 621, so that the support member 320 can support the two extension edges 621. At the same time, the clearance opening 301 in the support member 320 corresponds to the overlapping part of the two extension edges 621, thereby facilitating the correction component 400 to push the overlapping part of the two extension edges 621 apart from the other side of the extension edges 621.

[0059] The first driving component 310 can be configured as a motor driving mechanism, a cylinder driving mechanism, a hydraulic driving mechanism, or other driving mechanisms. The first driving component 310 can also be selected from other types of driving mechanisms. Those skilled in the art can make flexible settings according to actual needs. The embodiments of this application are not limited here.

[0060] Optionally, such as Figure 4 As shown, Figure 4A partial schematic diagram of a battery pack alignment device according to an embodiment of this application is shown. The support member 320 includes: a connecting portion 321, a first support arm 322, and a second support arm 323; the connecting portion 321 is connected to the first drive member 310, and the first support arm 322 and the second support arm 323 are connected to the same side of the connecting portion 321, and the first support arm 322, the second support arm 323 and the connecting portion 321 enclose to form a clearance opening 301; the first support arm 322 is used to support one of the two extended sides 621, and the second support arm 323 is used to support the other of the two extended sides 621.

[0061] In the embodiments of this application, a first support arm 322 and a second support arm 323 are provided on the same side of the connecting portion 321, with the first support arm 322 and the second support arm 323 spaced apart, so that the first support arm 322, the second support arm 323 and the connecting portion 321 enclose and form a clearance opening 301. The first support arm 322 and the second support arm 323 then provide support for the two extending edges 621 respectively, so that the overlapping portion of the two extending edges 621 is located between the first support arm 322 and the second support arm 323, so that the correction component 400 can be used to push the overlapping portion of the extending edges 621 apart. The structure is simple and easy to operate and control.

[0062] like Figure 7 and Figure 8 As shown, Figure 7 This diagram shows a battery pack alignment device according to an embodiment of the present application before alignment begins. Figure 8 A schematic diagram of the support assembly supporting the extended edge of the membrane layer according to an embodiment of this application is shown. During the calibration operation, after the transfer assembly 200 carrying the battery 600 moves to a preset position, the support assembly 320 can be driven to move as a whole by the first drive member 310, so that the first support arm 322 extends to one side of the first extended edge 621a to support the non-overlapping portion of the first extended edge 621a; correspondingly, the second support arm 323 extends to one side of the second extended edge 621b to support the non-overlapping portion of the second extended edge 621b.

[0063] Optionally, such as Figure 4 As shown, at least one of the first support arm 322 and the second support arm 323 is movably connected to the connecting part 321. The first support arm 322 and the second support arm 323 can move relative to each other to adjust the size of the clearance opening 301.

[0064] In the embodiments of this application, by setting at least one of the first support arm 322 and the second support arm 323 to be movably connected to the connecting part 321, the distance between the first support arm 322 and the second support arm 323 can be adjusted, thereby adjusting the size of the formed clearance opening 301 to meet the correction requirements of different overlap sizes of the two extended edges 621 and improve the applicability of the correction device.

[0065] Specifically, a groove can be provided in the connecting part 321, and the first support arm 322 and / or the second support arm 323 can be slidably connected to the groove. At the same time, a locking member can also be provided to lock the position of the first support arm 322 and / or the second support arm 323 on the connecting part 321, thereby facilitating flexible adjustment of the size of the clearance opening 301 according to the structure of the overlapping part of the extension edge 621.

[0066] Optionally, such as Figure 4 As shown, the correction assembly 400 includes a second drive member 410 and a lever 420; the lever 420 is movably connected to the base 100, and the second drive member 410 is connected to the lever 420 for driving the lever 420 to move from the other side of the two extension edges 621 toward the extension edges 621, and pushing the two extension edges 621 to at least partially separate via the lever 420.

[0067] In the embodiments of this application, the second driving member 410 can drive the lever 420 to move closer to or away from the extension edge 621, so that the lever 420 can push the extension edge 621 from the other side of the two extension edges 621, so that the overlapping part of the two extension edges 621 is separated from each other, thereby realizing the correction of the relative position of the two extension edges 621.

[0068] Reference Figures 8 to 10 As shown, Figure 8 This illustration shows a schematic diagram of a support component supporting an extension edge of a membrane layer according to an embodiment of this application. Figure 9 This illustration shows a schematic diagram of the correction component in an embodiment of this application pushing the two extended edges apart. Figure 10 An embodiment of this application is shown. Figure 9 An enlarged view of part A, shown in the middle circle.

[0069] In practical applications, after the first support arm 322 and the second support arm 323 respectively support the non-overlapping portions of the two extension edges 621, the second driving member 410 drives the lever 420 to move, so that the lever 420 moves closer to the side of the two extension edges 621 away from the support member 320, and pushes the two extension edges 621 to move. At this time, the overlapping portion of the two extension edges 621 is exactly located at the clearance opening 301 of the support member 320. Under the pushing action of the lever 420, the overlapping portion of the two extension edges 621 will separate from each other, thereby realizing the correction of the relative position of the two extension edges 621.

[0070] Then, the lever 420 is moved by the second driving member 410, and the support member 320 is moved by the first driving member 310, so as to reset the lever 420 and the support member 320 for the next battery 600 calibration operation.

[0071] The second driving component 410 can be a motor driving mechanism, a cylinder driving mechanism, a hydraulic driving mechanism, or other types of driving mechanisms. Those skilled in the art can make flexible settings according to actual needs, and the embodiments of this application are not limited here.

[0072] Optionally, such as Figure 4 As shown, the calibration assembly 400 also includes a connecting plate 430 and a slide rail 440; the slide rail 440 is mounted on the base 100, the connecting plate 430 is slidably connected to the slide rail 440, the lever 420 is connected to the connecting plate 430, and the second driving member 410 is connected to the connecting plate 430 to drive the connecting plate 430 to slide along the slide rail 440 and drive the lever 420 to move through the connecting plate 430.

[0073] In the embodiments of this application, a slide rail 440 is provided on the base 100, the connecting plate 430 is slidably connected to the slide rail 440, and the lever 420 is installed on the connecting plate 430 so that the movement of the lever 420 is more flexible through the cooperation of the slide rail 440 and the connecting plate 430. At the same time, it can also play a guiding and limiting role in the movement of the lever 420.

[0074] The extension direction of the slide rail 440 can be set to be consistent with the overlapping direction of the two extension edges 621, so as to facilitate the movement of the lever 420 toward the extension edge 621 by the second driving member 410, so as to correct the relative position of the two extension edges 621.

[0075] Optionally, such as Figure 5 As shown, Figure 5 A schematic diagram of a transfer assembly according to an embodiment of this application is shown; the transfer assembly 200 includes: a transfer arm 210 and a gripper mechanism 220; the transfer arm 210 is movably connected to the base 100, and the gripper mechanism 220 is connected to the transfer arm 210, and the gripper mechanism 220 is used to hold the battery 600.

[0076] In the embodiments of this application, the transfer arm 210 can drive the gripper mechanism 220 to move, and the gripper mechanism 220 can hold the battery 600 to transfer the battery 600 from the previous process to a preset position. At the same time, during the calibration of the film layer 620 of the battery 600, the gripper mechanism 220 clamps and fixes the battery 600 to perform the corresponding calibration operation.

The second gripper 223 can move relative to the fixed plate 221 to move closer to or further away from the first gripper 222.

[0078] In the embodiments of this application, by setting the first gripper 222 to be fixedly connected to the fixed plate 221 and the second gripper 223 to be movably connected to the fixed plate 221, the second gripper 223 can cooperate with the first gripper 222 to clamp the battery 600 by moving relative to the fixed plate 221.

[0079] Specifically, a third driving member can be provided in the fixed plate 221. The third driving member is connected to the second gripper 223. The second gripper 223 can be moved by the third driving member, thereby adjusting the distance between the first gripper 222 and the second gripper 223.
