Description

Technical Field

[0001] The present invention relates to the technical field of battery aluminum shell production, and specifically to a cutting tooling for new energy battery aluminum shell production. Background Art

[0002] A battery aluminum shell refers to a battery outer shell made of aluminum alloy material, which is mainly used for encapsulating various batteries such as lithium-ion batteries and nickel-metal hydride batteries, playing roles such as protecting the internal battery cells, isolating the external environment, supporting the battery structure, and assisting in heat dissipation.

[0003] The battery aluminum shell is a thin-walled rectangular shell structure with a length and height greater than the width. During cutting, generally, multiple battery aluminum shells are arranged and attached together. After being clamped and limited at the front and rear sides, the cutting tool moves from the rear to the front to cut the battery aluminum shells in sequence. However, the following problems exist in this cutting process: 1. A number of battery aluminum shells arranged and attached together are only fixed on one side of the cutting position. When cutting, since the battery aluminum shell is a thin-walled shell structure, and the cut battery aluminum shells will fall down, and the uncut battery aluminum shells are lacking the rear-side limit, it is easier to cause the battery aluminum shells to be deformed under force. Moreover, when multiple battery aluminum shells arranged and attached together are clamped and moved closer to the cutting position, the battery aluminum shells in the middle will have displacement errors due to insufficient clamping force. In the case where the ends are not aligned subsequently, there will be dimensional deviations between the cut finished products; 2. There are a large number of cutting scraps generated during the cutting process. The scraps are adsorbed on the inner and outer walls of the cutting position of the battery aluminum shell and on the operation platform. This not only pollutes the working environment and requires regular cleaning, but also easily causes the subsequent loaded battery aluminum shells to be placed unevenly. Summary of the Invention

[0016] One or more of the above technical solutions in the embodiments of the present invention have at least one of the following technical effects: 1. According to a cutting tool for producing an aluminum shell of a new energy battery provided by an embodiment of the present invention, through the clamping mechanisms and pressing mechanisms on both sides of the cutting position of the battery aluminum shell, while the pressing mechanism presses the upper end of the battery aluminum shell, the clamping mechanisms complete the partition clamping operation of multiple groups of battery aluminum shells, so that the battery aluminum shells on both sides always remain vertical during the cutting process, and when the pressing mechanism moves upward to release the pressing, the clamping mechanisms also automatically release the clamping of the battery aluminum shells, so that the battery aluminum shells can be smoothly pushed by the pushing plate under the limitation of the clamping mechanism; the battery aluminum shells are divided into multiple groups for clamping, and in combination with the method of pushing at the end, it is avoided that too many products are clamped at one time, resulting in displacement deviation of the products in the middle during feeding, ensuring that the displacement amounts of multiple battery aluminum shells are consistent after each cutting, so as to ensure the neatness of the cutting port and increase the product qualification rate.

[0017] 2. According to a cutting tool for producing an aluminum shell of a new energy battery provided by an embodiment of the present invention, the inner support mechanism extends into the vicinity of the cutting position of the battery aluminum shell to support the inner wall of the battery aluminum shell, reducing the problem of warping deformation of the cutting port caused by excessive cutting force during the cutting process of the battery aluminum shell.

[0018] 3. According to a cutting tool for producing an aluminum shell of a new energy battery provided by an embodiment of the present invention, the elastic anti-chip cover is provided to make the cutting operation in a relatively sealed environment, avoiding more chips from splashing onto the workbench. The chips on the inner and outer walls of the cutting position of the battery aluminum shell are adsorbed by a vacuum cleaner. By cooperating with the pressure contact rod and the push rod, the automatic diversion of cutting waste and the automatic recycling of the pull-out drawer are realized, and the waste chips can be self-cleaned and continuously collected, ensuring the working environment and efficiency.

[0019] 4. The right end of the battery aluminum shell is resisted by the rectangular alignment block, and the left end of the battery aluminum shell is pushed by the push plate, which not only seals the two ends of the battery aluminum shell, but also ensures that the ends of the battery aluminum shell are aligned, reducing the cutting error between the battery aluminum shells.

DETAILED DESCRIPTION

[0028] In order to make the above - mentioned objects, features and advantages of the present invention more obvious and understandable, the following will describe the specific embodiments of the present invention in detail with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0029] Please refer to Figure 1 and Figure 2 , a cutting tooling for the production of aluminum shells of new - energy batteries, which includes a workbench 1. On the left side of the upper end of the workbench 1, there is a feeding mechanism 2 for pushing the aluminum shells of the batteries for feeding. The feeding mechanism 2 includes a T - shaped slide rail 21 fixedly connected to the left side of the upper end of the workbench 1. A feeding plate 22 is slidably connected to the T - shaped slide rail 21 through an electric slider. A pushing plate 23 is slidably connected to the upper end of the feeding plate 22.

[0030] Continue to refer to Figure 1 , Figure 2 and Figure 3 , on the upper end of the workbench 1, on the right side of the feeding mechanism 2, there is an inverted U - shaped plate 11. A cutting member 3 for cutting the aluminum shells of the batteries is provided on the inverted U - shaped plate 11. The cutting member 3 is composed of a high - speed rotating blade and a protective cover. Through holes are provided on the side wall of the protective cover. The upper end of the protective cover is fixedly connected to the bottom end of a hydraulic telescopic rod. The fixed section of the hydraulic telescopic rod is fixedly connected to the horizontal section of the inverted U - shaped plate 11; a horizontal plate 12 is provided on the upper end of the workbench 1 through a height - increasing plate; an elastic anti - chip cover 4 is fixedly provided at the lower part of the protective cover. The elastic anti - chip cover 4 is used to protect against the flying chips during the cutting of the aluminum shells of the batteries; pressing mechanisms 5 are symmetrically arranged on both sides of the elastic anti - chip cover 4. The pressing mechanisms 5 are used to press both sides of the cutting part of the aluminum shells of the batteries; on the opposite sides of the two pressing mechanisms 5, a set of clamping mechanisms 6 is provided respectively. The clamping mechanisms 6 are used to clamp a plurality of aluminum shells of the batteries; the cutting tooling also includes an inner - support mechanism 8. The inner - support mechanism 8 is used to provide inner support for the right side of the aluminum shell of the battery during the cutting process; a rotating roller 13 is rotatably connected to the upper end of the workbench 1 through a mounting seat between the feeding mechanism 2 and the clamping mechanism 6. The height of the rotating roller 13 is the same as the height of the horizontal plate 12. The setting of the rotating roller 13 reduces the friction when the aluminum shell of the battery moves.

[0031] First, load the battery aluminum shell. First, start the electric slider and slide the loading plate 22 to the left side of the T-shaped slide rail 21, which is convenient for placing the battery aluminum shells on the loading plate 22 in batches. In the initial state, the pushing plate 23 is located at the leftmost side of the loading plate 22. Each time, multiple battery aluminum shells are placed on the upper end of the loading plate 22 as a group. During the placement process of each group of battery aluminum shells, they are in a slightly inclined state, and the inclination angle is less than 10 degrees, which is convenient for subsequent clamping and simultaneous correction of the placed battery aluminum shells. The sliding setting of the T-shaped slide rail 21 makes it only necessary to align with the clamping mechanism 6 on the left side when loading the battery aluminum shell. After all the loading is completed, start the electric slider to drive the loading plate 22 and the battery aluminum shells on the upper side into the right clamping mechanism 6 to complete the preliminary limit of the battery aluminum shell. The left and right movement of the pushing plate 23 can be driven by an electric telescopic cylinder (the electric telescopic cylinder is not shown in the figure), which is prior art and will not be elaborated here; the left and right movement of the T-shaped slide rail 21 is convenient for loading and placing longer battery aluminum shells, and the movement of the pushing plate 23 is convenient for the battery aluminum shell to intermittently move towards the cutting position during the operation. Under the limited length of the workbench 1, it can not only meet the convenient loading but also meet the operation movement requirements.

[0032] The horizontal plate 12 is provided to make the heights of the battery aluminum shells equal when placed, and the horizontal plate 12 on the right side of the cutting member 3 is convenient for placing the battery aluminum shells after cutting. The cutting member 3 performs cutting operations on multiple battery aluminum shells from top to bottom under the action of the hydraulic telescopic rod.

[0033] It should be noted that in the prior art, the number of battery aluminum shells cut at one time is forty, and the specific number can fluctuate according to the actual situation. The number of cuts in this application is greater than thirty and less than forty. Without significantly affecting the cutting efficiency, multiple battery aluminum shells are fixed in different areas to avoid the problem that the fallen battery aluminum shells in the traditional cutting method have no auxiliary support for the uncut battery aluminum shells.

[0034] Refer to Figure 1 and Figure 3 As shown in and, the clamping mechanism 6 includes a fixed rod 61 detachably connected to the vertical section of the inverted U-shaped plate 11. Two limiting plates 62 for limiting the front and rear sides of the battery aluminum shell are symmetrically arranged on the fixed rod 61. At least one adaptation adjustment member 63 for separating and limiting multiple groups of battery aluminum shells is arranged between the two limiting plates 62. A pushing assembly 64 is arranged above the adaptation adjustment member 63.

[0035] It should be noted that the number and installation position of the adaptation adjustment member 63 can be adjusted according to actual needs. In the attached drawings of this application, two adaptation adjustment members 63 are selected for installation.

[0036] Continue to refer to Figure 5 and Figure 6, the adaptation adjusting member 63 includes a rectangular block 631 detachably connected to the fixed rod 61. A through hole 632 is formed through the front and rear of the rectangular block 631. Two symmetrically arranged protruding blocks 633 are slidably disposed in the through hole 632. The two protruding blocks 633 are connected by a spring. A plurality of ball bearings (not shown in the figure) for reducing friction are rotatably provided on the opposite sides of the two protruding blocks 633. The ball bearings can reduce the sliding friction between the battery aluminum shell and the protruding block 633 when the battery aluminum shell is pushed. Tapered surfaces are provided at the upper ends of the opposite ends of the two protruding blocks 633. A relief hole 634 communicating with the through hole 632 is formed at the upper end of the rectangular block 631. A T-shaped extrusion block 635 is slidably connected up and down in the relief hole 634. The bottom end of the transverse end of the extrusion block 635 is connected to the rectangular block 631 by a pressing spring.

[0037] It should be noted that both the limit plate 62 and the adaptation adjusting member 63 are detachably assembled on the fixed rod 61. During actual use, the distance between the limit plate 62 and the adaptation adjusting member 63 or between two adaptation adjusting members 63 is adjusted according to the number of battery aluminum shells in each group. The number of adaptation adjusting members 63 can also be selected according to actual needs. The limit plate 62 and the adaptation adjusting member 63 are fixed to the fixed rod 61 through existing fixing structures, such as bolts. When placing the battery aluminum shells, the loading plate 22 is located at the leftmost side of the T-shaped slide rail 21. The right side of the battery aluminum shell is located at the position of the left clamping mechanism 6. A plurality of battery aluminum shells are placed in a group. The right sides of the battery aluminum shells in each group are respectively located between the limit plate 62 and the adaptation adjusting member 63 or between two adaptation adjusting members 63. For the convenience of description, the space between the limit plate 62 and the adaptation adjusting member 63 and the space between two adaptation adjusting members 63 are defined as the placement space. In the natural state, the distance between the two protruding blocks 633 is the smallest under the action of the spring, and at this time, the extrusion block 635 is located at the upper end of the rectangular block 631 under the action of the pressing spring. In this state, the distance of the plurality of placement spaces is the largest, which is convenient for placing a plurality of aluminum shells in each group. A plurality of groups of battery aluminum shells are sequentially placed in the corresponding placement spaces, and the loading plate 22 is moved to the right to move the plurality of groups of battery aluminum shells to the right clamping mechanism 6 on the right, so that both the left and right sides of the cutting part of the battery aluminum shell are in a clamped state.

[0038] Refer to Figure 1 、 Figure 3 、 Figure 4 and Figure 6, the pressing mechanism 5 includes a fixing plate 51 fixedly connected between two vertical sections of the inverted U-shaped plate 11. Two telescopic cylinders 52 are symmetrically and fixedly connected to the fixing plate 51 in the front and back. The telescopic sections of the telescopic cylinders 52 slide through the bottom end of the fixing plate 51. The bottom end of the telescopic cylinder 52 is fixedly connected with a moving plate 53 that moves up and down. The right side of the bottom end of the moving plate 53, away from one side of the telescopic cylinder 52, is fixedly connected with a pressing plate 54 through a connecting rod. One side of the pressing plate 54 close to the elastic anti-chip cover 4 is fixedly connected to the elastic anti-chip cover 4 through a rectangular strip.

[0039] In the initial state, the pressing plate 54 is located above the battery aluminum shell. At the same time, the telescopic cylinders 52 located above the fixing plate 51 are started. The telescopic cylinders 52 synchronously drive the moving plate 53 to move downward. The moving plate 53 will drive the pressing plate 54 to move downward to the upper end of the battery aluminum shell. Since the pressing plate 54 and the elastic anti-chip cover 4 are fixedly connected through a rectangular strip, the pressing plate 54 will synchronously drive the elastic anti-chip cover 4 to move downward, and the bottom end of the pressing plate 54 is flush with the bottom end of the elastic anti-chip cover 4. When the pressing plate 54 is pressed down to the upper end of the battery aluminum shell, the bottom end of the elastic anti-chip cover 4 also fits against the upper end of the battery aluminum shell, so that both sides of the cutting part of the battery aluminum shell are inside the elastic anti-chip cover 4. It should be noted that the elastic anti-chip cover 4 is made of an elastic material and can be selected according to requirements during use, such as silicone rubber, metal rubber, plastic elastomer, etc.

[0040] Refer to Figure 3 and Figure 6 , the pushing component 64 includes an ear seat fixedly connected to the left side of the moving plate 53. A through hole penetrating up and down is opened on the ear seat. A limiting rod 641 is slidably connected in the through hole. The bottom end of the limiting rod 641 is fixedly connected with a pushing bar 642. A compression spring is sleeved on the limiting rod 641, and both ends of the compression spring are respectively fixedly connected to the ear seat and the pushing bar 642.

[0041] During the downward movement of the moving plate 53, the ear seat will move downward synchronously. The limiting rod 641 on the ear seat drives the pushing bar 642 to first contact the upper end of the extrusion block 635. During the continuous downward movement of the moving plate 53, the compression spring will be compressed. The extrusion block 635 presses the protruding block 633 downward under the pressure of the pushing bar 642, so that the protruding blocks 633 in each rectangular block 631 move toward the front and back sides, and the distance of each placement space is reduced. At this time, the inclined battery aluminum shell will gradually be perpendicular to the placement surface under the pressing action of the protruding block 633, and the side surfaces of each group of battery aluminum shells are clamped in a divided area. When the compression spring is compressed to the shortest state, the moving plate 53 will drive the pressing plate 54 to press down to the upper end of the battery aluminum shell.

[0042] Refer to Figure 1 and Figure 7, the inner support mechanism 8 includes a sliding block 81 that is slidably connected to the horizontal plate 12 left and right. On the left side of the sliding block 81, there are multiple groups of rectangular alignment blocks 82. The right side of the rectangular alignment block 82 is slidably connected to the sliding block 81 through a sliding rod, and the right side of the sliding rod slidably penetrates the right side of the sliding block 81. A return spring is sleeved on the sliding rod, and both ends of the return spring are fixedly connected between the sliding block 81 and the rectangular alignment block 82.

[0043] Continue to refer to Figure 7 , on the left side wall of the rectangular alignment block 82, a plurality of rectangular through holes are evenly opened from front to back. Rectangular guide blocks 83 are fixedly connected symmetrically up and down in each rectangular through hole. On the side of the sliding block 81 close to the rectangular alignment block 82, a groove is opened, and an inner support module is detachably connected in the groove. The inner support module includes a rectangular seat fixedly connected in the groove. On the left side of the rectangular seat corresponding to the rectangular through holes, a plurality of groups of inner support bars 84 are hinged. Each group of inner support bars 84 is composed of two inner support bars 84 that are symmetrically distributed up and down, and a torsion spring is arranged at the connection of the inner support bar 84 and the rectangular seat. Each group of inner support bars 84 gradually approaches from left to right.

[0044] First, according to the multiple placement spaces formed by the limiting plate 62 and the adaptive adjustment member 63, select an inner support module with a matching number. When the inner support module is assembled, the rectangular seat can be fixed in the groove opened on the sliding block 81 through screws, and each group of inner support bars 84 is correspondingly placed into the rectangular through holes opened on the sliding block 81; initially, under the limitation of the rectangular alignment block 82, the vertical distance between the two inner support bars 84 in each group of inner support bars 84 is less than the inner height of the battery aluminum shell. At this time, the torsion spring connecting the inner support bars 84 is in a compressed state. Specifically, during work, the sliding block 81 is pushed to move left to the working position by an external driving device. When the feeding mechanism 2 drives the battery aluminum shell to feed right and up, the left side of the inner support bar 84 first contacts the right side of the battery aluminum shell. As the battery aluminum shell continues to move right, the battery aluminum shell will push the rectangular alignment block 82 to move towards the sliding block 81. Under the limiting action of the sliding block 81 and the rectangular guide block 83, the two inner support bars 84 gradually open. While the left side of the inner support bar 84 extends into the battery aluminum shell, it gradually opens and abuts against the inner upper and lower walls of the battery aluminum shell, thereby performing inner support on the battery aluminum shell.

[0045] Refer to Figure 3 and Figure 6, the cutting tooling for the production of aluminum shells of new energy batteries further includes a collection component 7. The collection component 7 includes a collection bin 71 opened on the workbench 1. A drawer 711 with an upward opening is slidably arranged in the collection bin 71. A dust collector is arranged at the front side of the workbench 1 corresponding to the position of the drawer 711. At the opening of the collection bin 71 on the upper end of the workbench 1, there are two groups of rectangular plates 72 arranged symmetrically left and right. Each group of rectangular plates 72 consists of two front and rear rectangular plates 72. A rotating plate 73 is hinged between the front and rear rectangular plates 72 through a torsion spring. In the state where the torsion spring is not stressed, the height of the rotating plate 73 is the same as that of the horizontal plate 12, and the gap distance between the two rotating plates 73 is greater than the thickness of the blade.

[0046] Continue to refer to Figure 3 and Figure 6 , there are two horizontal plates 12 arranged left and right. There is a gap between the two horizontal plates 12 and directly below the cutting member 3. Symmetrically front and rear circular holes are opened at the positions of the two horizontal plates 12 close to the gap. A push rod 74 is slidably arranged in the circular holes. A compression spring is sleeved on the outside of the push rod 74 and above the horizontal plate 12. The two ends of the compression spring are respectively connected to the horizontal plate 12 and the top of the push rod 74; the bottom end of the protective cover is symmetrically fixedly connected with a cooperating pressure contact rod 75.

[0047] After the clamping mechanism 6 clamps the side of the battery aluminum shell, the pressing mechanism 5 applies a downward pressure to the battery aluminum shell, and the inner support mechanism 8 provides inner support to the right side of the battery aluminum shell; then press down the cutting member 3 so that the cutting member 3 cuts the battery aluminum shell. During the cutting process, the protective cover drives the cooperating pressure contact rod 75 to descend synchronously. The cooperating pressure contact rod 75 simultaneously presses the left and right push rods 74. The bottom end of the push rod 74 will contact the top end of the rotating plate 73 and gradually press the rotating plate 73 to rotate downward. The vacuum cleaner on the front side of the drawer 711 is always in operation during the cutting process. The negative pressure causes air to enter the inside of the elastic anti-chip cover 4 from the gap between the bottom of the elastic anti-chip cover 4 and the adaptive adjustment member 63 and the through holes of the protective cover. The flowing air blows the chips adsorbed on the inner and outer walls at the cutting position of the battery aluminum shell into the drawer 711, facilitating the adsorption and collection of the chips generated during the cutting process. Both ends of the battery aluminum shell are blocked by the rectangular alignment block 82 and the push plate 23, so that the air flow enters the inside of the elastic anti-chip cover 4 from the gap and the through holes as much as possible. The drawer 711 can be pulled backward for timely cleaning; after each cutting is completed, first release the downward pressure of the pressing mechanism 5, and at the same time release the clamping force of the clamping mechanism 6 on the battery aluminum shell. The sliding block 81 drives the cut battery aluminum shell to move a certain distance to the right synchronously. During the continuous rightward movement of the sliding block 81, the spring between the sliding block 81 and the rectangular alignment block 82 will gradually return to its initial state, and the inner support strip 84 will no longer support the inside of the battery aluminum shell. Then, use an external pushing device to push the cut battery aluminum shell for blanking, and then start a new round of cutting operations.
