Description

Technical Field

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

[0002] As a crucial component of the battery, the battery casing needs to be sized to match the internal components such as the battery cells and electrodes. To ensure that the overall dimensions of the battery meet design requirements, the battery casing typically needs to be precisely cut.

[0003] Battery casing cutting typically involves the coordinated action of multiple parts. For example, during cutting, a dust extraction component removes fine particles generated during the cutting process, and a waste removal component removes waste materials after cutting. In existing technologies, the cutting, dust extraction, and waste removal components each typically have their own corresponding drive components. These components move to different positions to perform the relevant operations on the battery casing. Clearly, existing devices have a large number of drive components, occupy a large volume, require ample installation space, and their separate control design makes the control process relatively complex.

[0004] Therefore, it is necessary to improve the existing battery casing cutting device. Utility Model Content

[0005] This application provides a battery casing cutting device, which aims to solve the problems of existing battery casing cutting devices having a large number of driving components, high requirements for installation space, and relatively complex control processes due to their split control design.

[0006] To achieve the above objectives, this application proposes a battery casing cutting device. The battery casing cutting device includes:

The sliding mounting base is connected to the driving element and moves laterally under the drive of the driving element to move the cutting element to or out of the cutting operation area.

[0009] The waste discharge assembly includes a guide component disposed below the cutting operation area. A first roller structure is provided between the guide component and the sliding mounting base. The first roller structure is used to drive the guide component to move vertically when the sliding mounting base moves laterally.

[0010] A vacuuming assembly includes a guide seat and a vacuuming component rotatably connected to the guide component. A second roller structure is provided between the vacuuming component and the guide seat. The second roller structure is used to limit the rotation of the vacuuming component by the traction of the vacuuming component when it moves vertically along with the guide component.

[0011] In some embodiments, the first roller structure includes:

[0012] A first groove plate is vertically connected to the sliding mounting base, and a first roller is connected to the end of the first groove plate away from the sliding mounting base;

[0013] The second groove plate is laterally connected to the guide component, and the second groove plate is laterally provided with a first guide limiting groove with a height difference at both ends;

[0014] The first roller is inserted into the first guide limiting groove.

[0015] In some embodiments, the first guide limiting groove includes a front section, a middle section, and a tail section;

[0016] The front section is close to the guide member, the tail section is far from the guide member, and the relative height of the front section is lower than the relative height of the tail section. The middle section obliquely connects the front section and the tail section.

[0017] In some embodiments, a second guide limiting groove is vertically formed on the first groove plate; the first roller structure further includes a roller mounting plate that is horizontally slidable, the roller mounting plate being provided with the first roller and the second roller, the second roller being located above the first roller, and the second roller being inserted into the second guide limiting groove.

[0018] In some embodiments, the guide is a through guide tube, and a first mating notch is provided at the top of the guide tube and on the side near the cutting member. The first mating notch is designed to fit the outer surface of the cutting member, and is used to avoid lateral movement of the cutting member and to block the cut battery casing waste when the cutting member leaves the cutting operation area.

[0019] In some embodiments, a second docking notch is provided at the top of the guide tube and on the other side opposite to the first docking notch. The second docking notch is used to avoid the rotation of the vacuum cleaner so that the vacuum cleaner can dock with the cutting operation area.

[0020] In some embodiments, a discharge port is provided below the guide member, and a telescopic tube is provided between the bottom end of the guide member and the discharge port, the telescopic tube being used to maintain the communication between the guide member and the discharge port.

[0021] In some embodiments, the guide seat includes two oppositely disposed side plates; the second roller structure includes:

[0022] The third guide and limiting groove is obliquely and upwardly opened on the two side plates;

[0023] There are two third rollers, which are located on both sides of the vacuum cleaner and are respectively inserted into the third guide limiting groove.

[0029] The connecting rod has one end fixedly connected to the rotating shaft of the pusher plate, and the other end is rotatably equipped with a fourth roller, which is inserted into the fourth guide limiting groove.

[0030] This application proposes the above-mentioned battery casing cutting device. The device comprises three components for cutting the battery casing: a first roller structure between the cutting component and the waste discharge component, a second roller structure between the waste discharge component and the guide seat, and a connection structure between the waste discharge component and the dust collection component. This design allows the guide and dust collection components to move synchronously to or out of the cutting area while the cutting component is driven by a drive unit. Therefore, this application's technical solution utilizes only a single drive unit with multiple roller structures to simultaneously achieve synchronous movement of the three components in different directions. Operation and control are simple, and the number of drive devices used is small, reducing size and space constraints. Attached Figure Description

[0040] See Figure 1As shown, this application proposes a battery casing cutting device 100. The battery casing cutting device 100 mainly includes four parts: a drive component 13, a cutting assembly 10, a waste discharge assembly 20, and a dust collection assembly 40. After the battery casing to be cut is fixed in the cutting work area, the cutting assembly 10 is responsible for completing the cutting operation, while the waste discharge assembly 20 discharges the battery casing waste generated during the cutting process, keeping the cutting work area clean. The dust collection assembly 40 can suck up the dust and debris generated during the cutting process, keeping the working environment clean.

[0041] Specifically, the cutting assembly 10 includes a sliding mounting base 11 and a cutting element 12 disposed on the sliding mounting base 11. The sliding mounting base 11 is the carrier of the cutting element 12, is connected to the driving element 13 and moves laterally under the drive of the driving element 13, so as to drive the cutting element 12 to accurately move to or out of the cutting operation area, thereby completing the cutting operation of the battery case in the further operation of the cutting element 12.

[0042] In one embodiment, the cutting member 12 includes an inner cutting head. As it moves with the sliding mounting base 11 toward the cutting work area, the inner cutting head extends into the interior of the battery case and then rotates around the inner wall of the battery case to complete the cutting operation on the battery case.

[0043] The waste discharge assembly 20 includes a guide 21 disposed below the cutting operation area. The guide 21 is used to receive waste generated during the cutting process. Typically, a channel is formed inside the guide 21, in which the waste generated during cutting is transported and discharged.

[0044] A first roller structure 30 is further provided between the guide component 21 and the sliding mounting base 11. The first roller structure 30 is used to drive the guide component 21 to move vertically when the sliding mounting base 11 moves laterally. In fact, the first roller structure 30 is the transmission structure between the sliding mounting base 11 and the guide component 21, so that the guide component 21 can be height adjusted when the sliding mounting base 11 moves laterally. Specifically, when the sliding mounting base 11 approaches the cutting operation area, the guide component 21 simultaneously approaches the cutting operation area to ensure accurate docking and ensure that the waste material can be smoothly discharged.

[0045] The vacuuming assembly 40 includes a guide seat 41 and a vacuuming component 42 rotatably connected to the guide member 21. A second roller structure 50 is provided between the vacuuming component 42 and the guide seat 41. The second roller structure 50 is used to limit the rotation of the vacuuming component 42 when it moves vertically along with the guide member 21. In this way, the vacuuming component 42 also moves synchronously with the sliding mounting base 11 and the guide member 21. When the battery casing does not need to be cut, each component can simultaneously exit the cutting operation area to facilitate the fixing of the battery casing. When the battery casing needs to be cut, each component simultaneously approaches the fixed battery casing and reaches the predetermined position to ensure the smooth progress of the cutting operation.

[0046] Understandably, to ensure smooth and accurate movement of the sliding mounting base 11 and the guide component 21, corresponding support bases can be provided. For example, a first support base 110 can be provided for the sliding mounting base 11, and the driving component 13 can also be provided on the first support base 110; and a second support base 220 can be provided for the guide component 21. Furthermore, each support base is provided with a linear guide rail for the corresponding component to move, so that each component moves along the corresponding linear guide rail.

[0047] In summary, the battery casing cutting device 100 proposed in this application enables the material guide 21 and the dust suction component 42 to move synchronously when the cutting component 10 is driven by the drive component 13, that is, each component moves synchronously to or out of the cutting operation area. Therefore, the technical solution of this application can achieve synchronous movement of three components in different directions simultaneously using only a single drive component 13 in conjunction with multiple roller structures. The operation and control are simple, and the number of drive devices used is small, which can reduce the size and reduce the space restrictions for device installation. Figure 4 In the figures, (a) and (b) respectively present structural schematic diagrams of the battery cutting device of this application in the initial state and the working state.

[0048] See Figure 1 As shown, in some embodiments, the first roller structure 30 includes a first groove plate 31 and a second groove plate 33. The first groove plate 31 is vertically connected to the sliding mounting base 11, and a first roller 32 is connected to one end of the first groove plate 31 away from the sliding mounting base 11; the second groove plate 33 is horizontally connected to the guide member 21, and a first guide limiting groove 34 with a height difference at both ends is horizontally opened on it; the first roller 32 is inserted into the first guide limiting groove 34.

[0049] In this embodiment, the first groove plate 31 and the second groove plate 33 are respectively connected to the sliding mounting base 11 and the guide member 21. The first groove plate 31 can move with the sliding mounting base 11, and during the movement, the first roller 32 connected to it moves within the first guide limiting groove 34 on the second groove plate 33. Based on the shape of the first guide limiting groove 34 (with a height difference at both ends in the horizontal direction), the first roller 32 gradually pushes against the second groove plate 33 during its movement within the first guide limiting groove 34, causing the second groove plate 33 to drive the guide member 21 to move vertically according to the height difference.

[0050] Specifically, the first guide and limiting groove 34 includes a front section, a middle section, and a rear section; wherein, the front section is close to the guide member 21, the rear section is far from the guide member 21, the relative height of the front section is lower than the relative height of the rear section, and the middle section obliquely connects the front section and the rear section. In this way, as the first roller 32 moves from the rear section to the front section, based on its guiding and limiting function, the cutting member 12 is brought closer to the cutting operation area, and the guide member 21 is driven to rise.

[0051] The front and rear sections are both horizontally oriented, meaning that after the guide component 21 rises or falls to a certain height, its height remains unchanged as the sliding mounting base 11 continues to move horizontally. This facilitates precise control of the movement of each component and allows for sufficient margin.

[0052] See Figure 1 As shown, in some embodiments, a second guide limiting groove 36 is vertically provided on the first groove plate 31; the first roller structure 30 also includes a roller mounting plate 35 that is horizontally slidable, a first roller 32 and a second roller 37 are provided on the roller mounting plate 35, the second roller 37 is located above the first roller 32, and the second roller 37 is inserted into the second guide limiting groove 36.

[0053] In this embodiment, the first roller structure 30 is further designed. It not only enables the lifting and lowering of the guide component 21 based on the assembly between the first roller 32 and the first guide limiting groove 34, but also allows adjustment of the height of the sliding mounting base 11 and the cutting component 12 to accommodate the cutting of battery casings of different sizes and models. It is understood that, based on the assembly between the second guide limiting groove 36 and the second roller 37, after the sliding mounting base 11 adjusts its height, its second roller 37 remains within the second guide limiting groove 36. When the sliding mounting base 11 moves laterally, the second roller 37 can push against the roller mounting plate 35 and move in the same direction, thereby driving the first roller 32 to move within the first guide limiting groove 34, thus achieving the driving operation of the guide component 21.

[0054] For example, the sliding mounting base 11 and the driving member 13 are both disposed on the first support base 110. Furthermore, the first support base 110 is movably disposed on a height adjustment component (such as an adjustment mounting base, an adjustment slide rail, etc.). By providing a separate driving member 13 to drive the first support base 110 to move in the vertical direction, the height position of the sliding mounting base 11 and the cutting member 12 on it can be adjusted.

[0055] To ensure the stability and accuracy of the roller mounting plate 35 during movement, a linear guide rail corresponding to the roller mounting plate 35 can be further provided on the second support 220. This linear guide rail corresponding to the roller mounting plate 35 and the linear guide rail corresponding to the guide member 21 are located on different sides of the second support 220, which can further save space.

[0056] See Figure 3 As shown, in some embodiments, the guide member 21 is a through guide tube, and a first docking notch 211 is provided at the top of the guide tube and on the side near the cutting member 12. The first docking notch 211 is designed to fit the outer surface of the cutting member 12, and is used to avoid the lateral movement of the cutting member 12 and to block the cut battery casing waste when the cutting member 12 leaves the cutting operation area.

[0057] Understandably, since the cutting element 12 proposed in this application is an internal cutting head, after the cutting element 12 has finished cutting, the cut waste material is usually hung on the internal cutting head. At this time, in order to prevent the cut battery casing waste material from moving with the internal cutting head, the first docking notch 211 is designed. The shape design of the first docking notch 211 not only avoids the movement of the cutting element 12, but also effectively blocks the waste material, so that after the waste material is separated from the internal cutting head, it falls into the guide tube under its own gravity for guidance and conveying.

[0058] Additionally, a second docking notch 212 is provided at the top of the guide tube and on the other side opposite to the first docking notch 211. The second docking notch 212 is used to avoid the rotation of the dust collection component 42 so that the dust collection component 42 docks with the cutting operation area, ensuring that the dust collection component 42 can be kept in the optimal dust collection position, thereby maximizing the dust collection effect.

[0059] See Figure 1 As shown, in some embodiments, a discharge port 22 is provided below the guide member 21, and a telescopic tube 23 is provided between the bottom end of the guide member 21 and the discharge port 22. The telescopic tube 23 is used to maintain the communication between the guide member 21 and the discharge port 22.

[0060] In this embodiment, the telescopic tube 23 is generally made of a soft, wear-resistant, and corrosion-resistant material to ensure its long-term reliability and durability. The design of the telescopic tube 23 allows the guide 21 to maintain communication with the discharge port 22 while moving up and down within a certain range, preventing waste material from falling out during transmission.

[0061] See Figure 1 as well as Figure 2 As shown, in some embodiments, the guide seat 41 includes two opposing side plates 411; the second roller structure 50 includes a third guide limiting groove 52 and a third roller 51. The third guide limiting groove 52 is obliquely opened on the two side plates 411; there are two third rollers 51, which are disposed on both sides of the dust collection component 42 and are respectively inserted into the third guide limiting groove 52.

[0062] Understandably, as the vacuum cleaner 42 moves along the guide 21, the third rollers 51 on both sides of the vacuum cleaner 42 move along the third guide limiting groove 52. At this time, with the cooperation of the third rollers 51 and the third guide limiting groove 52, the special shape design of the third guide limiting groove 52 restricts the direction of movement of the vacuum cleaner 42, thereby allowing it to rotate and adjust its angle while following the guide 21, achieving the effect of the vacuum cleaner 42 rotating relative to the guide 21.

[0063] The assembly between the third guide limiting grooves 52 on both sides and the third rollers 51 on both sides makes the movement control of the vacuum cleaner 42 more stable and accurate.

[0064] See Figure 2 as well as Figure 3 As shown, in some embodiments, the device further includes a pushing assembly 70 disposed at the top of the vacuuming component 42. The pushing assembly 70 includes a pushing plate 71 and a third roller structure 72. The pushing plate 71 is rotatably disposed at the top of the vacuuming component 42; the third roller structure 72 is disposed between the pushing plate 71 and the guide component 21, and is used to drive the pushing plate 71 to rotate when the vacuuming component 42 moves with the guide component 21 and rotates.

[0065] In this embodiment, the pusher plate 71 is designed to rotate as the vacuum cleaner 42 rotates after the battery casing is cut out of the cutting area, thus pushing the waste material and preventing it from falling out of the second docking notch 212. The top edge of the pusher plate 71 is designed to conform to the shape of the battery casing to avoid obstructing its movement. The third roller structure 72 is positioned between the pusher plate 71 and the guide member 21 to control the movement of the pusher plate 71.

[0066] See Figure 3As shown, the third roller structure 72 further includes a fourth guide limiting groove 721 and a connecting rod 722. The fourth guide limiting groove 721 is laterally adjacent to the top end of the guide member 21; one end of the connecting rod 722 is fixedly connected to the rotation shaft of the pusher plate 71, and the other end is rotatably equipped with a fourth roller 723, which is inserted into the fourth guide limiting groove 721. Thus, due to the limiting effect of the fourth guide limiting groove 721 on the fourth roller 723, the connecting rod 722 will rotate relative to the fourth roller 723 during the rotation of the dust collection member 42 to adapt to its rotational changes. Based on this, the connecting rod 722 drives the pusher plate 71 to rotate, realizing the pushing operation of the pusher plate 71.
