Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, and in particular to a shaping device and a battery manufacturing system. Background Technology

[0002] During battery production, an insulating sleeve is typically fitted onto the battery cell to ensure its insulation performance. The insulating sleeve is usually tubular and, for ease of storage, is typically flattened and wound onto a reel. When fitting the insulating sleeve onto the battery cell, it needs to be pulled from the reel and cut to a predetermined length before being fitted onto the cell.

[0003] However, because the insulating sleeve is flattened during storage, it is not easy to directly apply it to the battery cell, and creases are formed on the insulating sleeve due to compression. These creases affect the insulating sleeve's coverage of the battery cell, thus hindering its protection. Utility Model Content

[0004] In view of this, the present application aims to provide a shaping device that can shape the insulating sleeve and improve the protection effect on the battery cell.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows: A shaping device for shaping an insulating sleeve includes a frame, a rotating mechanism mounted on the frame, and an expansion mechanism mounted on the rotating end of the rotating mechanism. The expansion mechanism includes an expansion portion disposed on the rotating end for the insulating sleeve to be fitted, and a first driving portion; The expansion section includes two expansion members slidably disposed on the rotating end, and the first driving section is capable of driving the two expansion members to move away from or towards each other; The rotating mechanism drives the expansion portion to rotate relative to the insulating sleeve, so that the two expansion members are respectively oriented toward the creases at the left and right ends of the insulating sleeve.

[0006] Furthermore, the expansion member has a convex arc-shaped contact surface on one side of the insulating sleeve; and / or, the end of the expansion member is provided with a guide surface, and the guide surface can guide the insulating sleeve to be fitted onto the expansion portion.

[0007] Furthermore, the rotating mechanism includes a rotating disk rotatably mounted on the frame, and a first motor mounted on the frame; the output shaft of the first motor is provided with a drive gear, and the rotating disk is provided with a driven gear meshing with the drive gear.

[0008] Furthermore, the first driving unit includes a bidirectional lead screw rotatably mounted on the rotating disk, and a second motor that drives the bidirectional lead screw to rotate; the bidirectional lead screw has two threaded sections with opposite directions of rotation, and the two expansion members are respectively screwed onto the two threaded sections.

[0009] Furthermore, the frame is provided with a loading and unloading mechanism, which includes a moving unit and a gripping unit driven by the moving unit to grip the insulating sleeve; the gripping unit is driven to move so as to put the outer insulating sleeve on the expansion portion and to remove the insulating sleeve from the expansion portion.

[0010] Furthermore, the gripping unit includes a second driving part connected to the mobile end, and two clamping blocks connected to the second driving part; the second driving part can drive the two clamping blocks to clamp the two ends of the insulating sleeve with the crease, so that the upper and lower sides of the insulating sleeve expand outward.

[0011] Furthermore, positioning grooves are formed on both opposite sides of the two clamping blocks, and the two ends of the insulating sleeve with the crease respectively abut against the two positioning grooves.

[0012] Furthermore, the moving units are configured as two separate units on opposite sides of the expansion portion, and each moving unit is provided with a gripping unit; the gripping unit includes a suction cup assembly, and the two suction cup assemblies can be driven to move and respectively adhere to opposite sides of the insulating sleeve.

[0013] Furthermore, the moving unit includes a linear module connected to the frame and a telescopic cylinder connected to the drive end of the linear module; the linear module can drive the telescopic cylinder to move along the extension direction of the expansion member, and the piston rod of the telescopic cylinder is connected to the gripping unit and can drive the gripping unit to move closer to or away from the expansion member.

[0014] Compared with related technologies, this application has the following advantages: (1) The shaping device described in this application can expand the insulating sleeve by setting two expansion members, so that the insulating sleeve is adjusted to a preset shape so that the insulating sleeve can be fitted onto the battery cell. At the same time, by setting the rotation mechanism, the expansion members can be driven to align with the creases of the insulating sleeve. While shaping the insulating sleeve, the expansion members can expand the crease position in a targeted manner, which is beneficial to eliminate the creases on the insulating sleeve and can effectively ensure that the insulating sleeve is evenly covered on the battery cell, thereby improving the protection effect of the battery cell.

[0015] (2) The arc-shaped contact surface reduces frictional damage to the insulating sleeve by providing a smooth transition. At the same time, the guide surface facilitates the placement of the insulating sleeve on the expansion portion, preventing damage to the insulating sleeve due to jamming during the placement process.

[0016] (3) The rotating disk provides a mounting base for the first drive unit and the expansion parts. At the same time, the gear meshing transmission method has high transmission efficiency and precision, and can accurately control the rotation angle of the rotating disk, so that the two expansion parts can be accurately aligned with the creases at the left and right ends of the insulating sleeve.

[0017] (4) By setting up a bidirectional lead screw, the two threaded sections on the bidirectional lead screw can drive the two expansion parts to move synchronously in opposite directions, ensuring the synchronicity of the expansion parts' movement, so as to ensure the shaping effect on the insulating sleeve.

[0018] (5) By setting up the loading and unloading mechanism, the automatic loading and unloading operation of the insulating sleeve on the expansion part can be realized, eliminating the need for manual placement and removal of the insulating sleeve, which significantly reduces the intensity of manual labor.

[0019] (6) By setting up a gripping mechanism consisting of a clamping block and a second driving part, while gripping and fixing the insulating sleeve, the two clamping blocks can clamp the two ends of the insulating sleeve with creases, so that the upper and lower sides of the insulating sleeve expand outward due to the clamping force. Thus, the insulating sleeve can be pre-expanded, which makes it easier to put the insulating sleeve on the expansion part.

[0020] (7) By setting a positioning groove on the clamping block, the clamping position of the insulating sleeve can be accurately positioned to ensure that the two clamping blocks always act on the end of the insulating sleeve with creases, so as to ensure that the insulating sleeve can expand due to clamping, and further facilitate the installation of the insulating sleeve on the expanded part.

[0021] (8) With the setting of two moving units and suction cup assembly, the two suction cup assembly can be adsorbed on the upper and lower sides of the insulating sleeve, improving the stability of gripping the insulating sleeve. At the same time, the two suction cup assembly can be driven by the two moving units to separate the upper and lower sides of the insulating sleeve, thereby pre-expanding the insulating sleeve so that the insulating sleeve can be fitted on the expanded part.

[0022] (9) By combining the linear module and the telescopic cylinder, the gripping unit can be driven to move, and the gripping unit can move in multiple dimensions, thus improving the flexibility of loading and unloading operations.

[0023] Another object of this application is to provide a battery production system having the shaping device described above.

[0031] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0032] An embodiment of the first aspect of this application provides a shaping mechanism for shaping an insulating sleeve 4.

[0033] In related technologies, the insulating sleeve 4 is flattened during storage, making it difficult to directly apply it to the battery cell, and creases are formed on the insulating sleeve 4 due to compression. The presence of these creases affects the covering effect of the insulating sleeve 4 on the battery cell, thus hindering the improvement of the battery cell's protection.

[0034] In view of this, in order to overcome the shortcomings of related technologies, the shaping device in this embodiment combines... Figure 1 , Figure 2 and Figure 3As shown, the overall design includes a frame 1, a rotating mechanism mounted on the frame 1, and an expansion mechanism mounted on the rotating end of the rotating mechanism.

[0035] The expansion mechanism includes an expansion section on the rotating end for the insulating sleeve 4 to be fitted, and a first driving section. The expansion section includes two expansion members 3 slidably disposed on the rotating end, and the first driving section is capable of driving the two expansion members 3 to move away from or towards each other. The rotation mechanism drives the expansion section to rotate relative to the insulating sleeve 4, so that the two expansion members 3 are respectively oriented towards the creases at the left and right ends of the insulating sleeve 4.

[0036] Therefore, by setting two expansion members 3, the insulating sleeve 4 can be expanded and adjusted to a preset shape so that the insulating sleeve 4 can be fitted onto the battery cell. At the same time, by setting a rotating mechanism, the expansion member 3 can be driven to align with the crease of the insulating sleeve 4. While shaping the insulating sleeve 4, the expansion member 3 can expand the crease position in a targeted manner, which helps to eliminate the crease on the insulating sleeve 4 and effectively ensures that the insulating sleeve 4 is evenly covered on the battery cell, thereby improving the protection effect of the battery cell.

[0037] Based on the above general introduction, specifically, the frame 1 of this embodiment has an upright plate-like structure, and two expansion members 3 extend outward in a direction perpendicular to the frame 1 and are arranged opposite to each other.

[0038] In some exemplary embodiments, the expansion member 3 has a convex arc-shaped contact surface on one side abutting the insulating sleeve 4. Simultaneously, the end of the expansion member 3 may be provided with a guide surface 301, which guides the insulating sleeve 4 to be fitted onto the expansion portion.

[0039] The arc-shaped contact surface and its smooth transition reduce frictional damage to the insulating sleeve 4. Simultaneously, the guide surface 301 facilitates the fitting of the insulating sleeve 4 onto the expansion portion, preventing damage to the insulating sleeve 4 due to jamming during fitting.

[0040] In some of the exemplary implementations, combined with Figure 4 As shown, the rotating mechanism includes a rotating disk 2 rotatably mounted on a frame 1, and a first motor 102 mounted on the frame 1. The output shaft of the first motor 102 is provided with a drive gear 1021, and the rotating disk 2 is provided with a driven gear 201 that meshes with the drive gear 1021.

[0041] The rotating disk 2 provides a mounting base for the first drive unit and the expansion member 3. At the same time, the gear meshing transmission method has high transmission efficiency and precision, and can accurately control the rotation angle of the rotating disk 2, so that the two expansion members 3 can be accurately aligned with the creases at the left and right ends of the insulating sleeve 4.

[0042] In a specific implementation, the frame 1 of this embodiment has mounting holes for the rotating disk 2. The rotating disk 2 is rotatably mounted in the mounting holes. The expansion portion and the first drive portion are located on one side of the rotating disk 2, and the first motor 102 is also located on the side where the expansion portion is located. Meanwhile, a driven gear 201 is provided on the other side of the rotating disk 2. The driven gear 201 is a ring-shaped rack that conforms to the edge of the rotating disk 2, and the output shaft of the first motor 102 can pass through the frame 1 and extend to the side where the driven gear 201 is located.

[0043] In some exemplary embodiments, the first drive unit includes a bidirectional lead screw 5 rotatably mounted on a rotating disk 2, and a second motor 501 that drives the bidirectional lead screw 5 to rotate. The bidirectional lead screw 5 has two threaded sections with opposite directions of rotation, and two expansion members 3 are respectively screwed onto the two threaded sections.

[0044] By setting up the bidirectional lead screw 5, the two threaded sections on the bidirectional lead screw 5 can drive the two expansion members 3 to move synchronously in opposite directions, ensuring the synchronicity of the movement of the expansion members 3, so as to ensure the shaping effect of the insulating sleeve 4.

[0045] In a specific implementation, the rotating disk 2 of this embodiment is also provided with a slide rail 202, and the end of the expansion member 3 is formed with a slider 302 that is slidably disposed on the slide rail 202. The slider 302 is screwed onto the bidirectional lead screw 5 so that the expansion member 3 can be moved by the rotation of the bidirectional lead screw 5.

[0046] In some exemplary embodiments, the frame 1 is provided with a loading and unloading mechanism, which includes a moving unit and a gripping unit driven by the moving unit to grip the insulating sleeve 4. The gripping unit is driven to move so as to put the outer insulating sleeve 4 onto the expansion portion and to remove the insulating sleeve 4 from the expansion portion.

[0047] By setting up the loading and unloading mechanism, the loading and unloading operation of the insulating sleeve 4 on the expansion section can be realized, eliminating the need for manual placement and removal of the insulating sleeve 4, and significantly reducing the intensity of manual labor.

[0048] Specifically, in some exemplary embodiments, the gripping unit includes a second drive unit 602 connected to the mobile end, and two clamping blocks 6 connected to the second drive unit 602. The second drive unit 602 is capable of driving the two clamping blocks 6 to clamp the two ends of the insulating sleeve 4 with creases, causing the upper and lower sides of the insulating sleeve 4 to expand outward.

[0049] By setting up a gripping mechanism consisting of a clamping block 6 and a second driving part 602, while gripping and fixing the insulating sleeve 4, the two clamping blocks 6 can clamp the two ends of the insulating sleeve 4 with creases, so that the upper and lower sides of the insulating sleeve 4 expand outward due to the clamping force. Thus, the insulating sleeve 4 can be pre-expanded, making it easier to put the insulating sleeve 4 on the expanded part.

[0050] In specific implementation, the second drive unit 602 of this embodiment is a conventional drive structure known to those skilled in the art, such as a cylinder, an electric push rod, a linear module 8, etc., which can drive the two clamping blocks 6 to move away from or closer to each other to achieve clamping of the insulating sleeve 4.

[0051] Furthermore, in some exemplary embodiments, positioning grooves 601 are formed on both opposite sides of the two clamping blocks 6, and the two ends of the insulating sleeve 4 with creases respectively abut against the two positioning grooves 601.

[0052] By providing a positioning groove 601 on the clamping block 6, the clamping position of the insulating sleeve 4 can be accurately positioned, ensuring that the two clamping blocks 6 always act on the creased end of the insulating sleeve 4, so that the insulating sleeve 4 can expand due to clamping, further facilitating the fitting of the insulating sleeve 4 onto the expanded part.

[0053] In specific implementation, the positioning groove 601 of this embodiment is V-shaped so that the end of the insulating sleeve 4 with creases can be locked in the positioning groove 601.

[0054] Furthermore, in some of the exemplary implementations, combined with Figure 5 As shown, in another embodiment, the moving units are configured as two separate units located on opposite sides of the expansion portion, and each moving unit is equipped with a gripping unit. The gripping unit includes a suction cup assembly 7, and the two suction cup assemblies 7 can be driven to move and respectively adhere to opposite sides of the insulating sleeve 4.

[0055] With the arrangement of two moving units and suction cup assembly 7, the two suction cup assembly 7 can be adsorbed on the upper and lower sides of the insulating sleeve 4, improving the stability of gripping the insulating sleeve 4. At the same time, the two suction cup assembly 7 can be driven by the two moving units to separate the upper and lower sides of the insulating sleeve 4, thereby pre-expanding the insulating sleeve 4 so that the insulating sleeve 4 can be fitted onto the expanded part.

[0056] In a specific implementation, the suction cup assembly 7 of this embodiment includes a base 701 connected to the moving end of the moving unit, and a plurality of suction cups 702 disposed on the base 701. The plurality of suction cups 702 are arranged along the length direction of the insulating sleeve 4, that is, the extension direction of the expansion member 3. Meanwhile, the base 701 is provided with an air passage communicating with each suction cup 702, and the base 701 is provided with a connector for communicating with the air passage and for communicating with an external negative pressure source.

[0057] In some exemplary embodiments, the moving unit includes a linear module 8 connected to the frame 1 and a telescopic cylinder 9 connected to the drive end of the linear module 8. The linear module 8 can drive the telescopic cylinder 9 to move along the extension direction of the expansion member 3, and the piston rod of the telescopic cylinder 9 is connected to the gripping unit and can drive the gripping unit closer to or away from the expansion member. Specifically, the linear module 8 can drive the gripping unit to move along the extension direction of the expansion member 3 to place the insulating sleeve 4 gripped by the gripping unit onto the expansion member, while the telescopic cylinder 9 can adjust the position of the gripping unit in the height direction so that the gripping unit can separate the upper and lower sides of the insulating sleeve 4 to achieve pre-expansion of the insulating sleeve 4.

[0058] Therefore, by combining the linear module 8 and the telescopic cylinder 9, the gripping unit can be driven to move, enabling the gripping unit to move in multiple dimensions and improving the flexibility of loading and unloading operations.

[0059] In practice, the frame 1 is provided with an outwardly extending bracket 101, and the linear module 8 is mounted on the bracket 101.

The rotation mechanism drives the expansion section to rotate relative to the insulating sleeve 4, so that the two expansion members 3 are respectively oriented towards the creases at the left and right ends of the insulating sleeve 4.

[0063] Furthermore, the frame 1 has an upright plate-like structure, and two expansion members 3 extend outward in a direction perpendicular to the frame 1 and are arranged opposite each other.

Meanwhile, the driven gear 201 is provided on the other side of the rotating disk 2. This driven gear 201 is a ring-shaped rack conforming to the edge of the rotating disk 2, and the output shaft of the first motor 102 can pass through the frame 1 and extend to the side where the driven gear 201 is located.

[0065] Furthermore, the first drive unit includes a bidirectional lead screw 5 rotatably mounted on the rotating disk 2, and a second motor 501 that drives the bidirectional lead screw 5 to rotate.

The linear module 8 can drive the telescopic cylinder 9 to move along the extension direction of the expansion member 3, and the piston rod of the telescopic cylinder 9 is connected to the gripping unit and can drive the gripping unit to move closer to or away from the expansion member.

[0067] In one embodiment, the gripping unit includes a second driving unit 602 connected to the mobile end, and two clamping blocks 6 connected to the second driving unit 602. The second driving unit 602 can drive the two clamping blocks 6 to clamp the two ends of the insulating sleeve 4 with folds, causing the upper and lower sides of the insulating sleeve 4 to expand outward.
