Technical Field
[0001] The utility model relates to the technical field of battery core foam cutting, and in particular to a battery core foam cutting device for adapting a battery pack. Background Art
[0002] Foam is a material made of foamed plastic particles, referred to as foam. Foam is divided into PU foam, anti-static foam, electric foam, EPE, anti-static EPE, CR, EVA, bridged PE, SBR and EPDM, etc. Foam has a series of characteristics such as elasticity, light weight, fast pressure-sensitive fixation, easy use, easy bending, ultra-thin volume and reliable performance. In the manufacturing process of battery packs, multiple battery cells need to be stacked along the thickness direction, and foam is placed between the battery cells to form a battery module. Some foams are called battery cell foams, which are consistent with commonly used foams. Battery cell foams need to be cut during the production process to adapt to different battery packs.
[0003] In the process of cutting the battery cell foam, the large-sized battery cell foam is cut into small-sized battery cell foams of the same size in batches mainly according to the size of the battery cells in the battery pack. The cutting process is mainly realized by a cutter, but in the actual cutting process, generally only the corners of the large-sized battery cell foam are abutted and fixed. In the actual cutting process, there is a certain distance between the corners of the battery cell foam and the cutting position, which lacks the necessary flattening and fixation near the cutting position. In the cutting process of the cutter, wrinkles and warped corners of the battery cell foam are easily caused, affecting the cutting of the next station. The existence of wrinkles and warped corners will further compress the cutting position of the large-sized battery cell foam, thereby causing unnecessary waste of battery cell foam.
[0004] Therefore, it is necessary to invent a cell foam cutting device for adapting to a battery pack to solve the above problems. Utility Model Content
[0005] In order to solve the deficiencies of the prior art, the purpose of the utility model is to provide a battery cell foam cutting device for adapting to battery packs, which solves the problem that there is a certain distance between the corner position of the battery cell foam and the cutting position in the prior art, resulting in a lack of necessary flattening and fixation near the cutting position. During the cutting process of the cutter, wrinkles and curled corners of the battery cell foam are easily caused, affecting the cutting of the next workstation. The presence of wrinkles and curled corners will further compress the cutting position of large-sized battery cell foam, thereby causing unnecessary waste of battery cell foam.
[0006] In order to achieve the above objectives, the utility model adopts the following technical solutions:
[0007] A core foam slitting device for adapting to a battery pack, comprising a slitting plate, a lifting member arranged directly above the slitting plate, and a square plate installed at the bottom end of the lifting member and capable of rotating 90 degrees and being locked. At the four corners of the slitting plate, there are corner fixing mechanisms for abutting and fixing the core foam at the corners. A sliding plate is slidably arranged at the bottom end of the square plate, and a sliding seat is slidably arranged at the bottom end of the sliding plate, and the sliding directions of the sliding plate and the sliding seat are perpendicular. A cutting knife for slitting the core foam is installed at the bottom end of the sliding seat. Telescopic frames capable of longitudinal expansion are installed in the middle of the four sides of the square plate. A side pressing roller capable of abutting against the top end of the core foam is rotatably installed at the bottom end of the telescopic frame, and a spring is sleeved on the telescopic frame;
[0008] When the cutting knife is in the slitting position, the telescopic frame is in a compressed state, and the side pressing roller presses tightly against the top end of the core foam.
[0009] As a preferred solution of the present invention, side clamping seats are detachably installed in the middle of the four sides of the square plate. The top end of the telescopic frame is connected to the bottom surface of the side clamping seat, and a mounting seat is installed at the bottom end of the telescopic frame. The side pressing roller is rotatably installed in the mounting seat.
[0010] As a preferred solution of the present invention, first slide rails are installed at the symmetric positions at the bottom end of the square plate. The sliding plate can slide along the two first slide rails. A second slide rail is installed at the bottom end of the sliding plate. The sliding seat can slide along the second slide rail, and the first slide rail is perpendicular to the second slide rail.
[0011] As a preferred solution of the present invention, a plurality of columns are arranged at the bottom end of the slitting plate, and a U-shaped frame is commonly installed between the bottom ends of the plurality of columns. The lifting member is detachably installed at the top of the U-shaped frame.
[0012] As a preferred solution of the present invention, a connecting plate is sleeved at the bottom end of the lifting part of the lifting member. An arc chuck is installed at the end of the connecting plate. A positioning stud capable of sliding along the arc of the arc chuck is installed at the top end of the square plate. A nut is threadedly sleeved on the part of the positioning stud located above the arc chuck. The maximum angle for the positioning stud to slide in the arc chuck is 90 degrees.
[0013] As a preferred solution of the present invention, long grooves with one end being an open end are opened at the four corners of the slitting plate. Sealing plates capable of closing the open ends of the long grooves are abutted at the four corners of the slitting plate. A screw rod is threadedly inserted into the sealing plate. A rotating frame is installed at one end of the screw rod located outside the slitting plate. An inserting column is installed at one end of the screw rod located inside the slitting plate. Inserting holes for the inserting column to rotate and insert are opened at the adapted positions inside the slitting plate.
[0014] As a preferred embodiment of the present utility model, the corner fixing mechanism includes a slider threadedly sleeved on a screw rod and slidable along a long groove, and a folding abutting frame detachably mounted on the top end of the slider through a mounting frame.
[0015] In the above technical solution, the technical effects and advantages provided by the present utility model are as follows:
[0016] In the present utility model, the corner fixing structures at the four corners of the slitting plate abut and fix at the four corner positions of the large-sized cell foam. During the actual slitting process, the lifting member moves vertically up and down, thereby driving the cutting knife to move down to the slitting position and slit the large-sized cell foam into small-sized cell foams. During the slitting process, the sliding plate slides along the bottom end of the square plate and the sliding seat slides along the bottom end of the sliding plate. And since the sliding direction of the sliding seat is perpendicular to that of the sliding plate, the cutting knife can perform a vertical movement within the plane at the bottom end of the square plate. At the same time, since the square plate can rotate 90 degrees at the bottom end of the lifting member, the cutting knife can perform a vertical movement cutting with different distance lengths within the plane, that is, the cell foam to be slit is adapted to different battery packs for use. During the process that the lifting member moves vertically up and down to drive the cutting knife to move down to the slitting position, the side pressing rollers first contact the top end of the cell foam. And under the forced expansion and contraction of the telescopic frame and the passive compression and limitation of the spring, when the cutting knife reaches the slitting position, the side pressing rollers are pressed tightly against the top end of the cell foam. Thus, during the slitting process by the cutting knife, multiple side pressing rollers press and fix near the slitting position, avoiding the wrinkles and corner warping near the slitting position of the cell foam caused by the shearing stress of the cutting knife, which further affects the slitting of the next working station, that is, avoiding the problem that the slitting position is further compressed due to the existence of wrinkles and corner warping, and finally maximizing the utilization of the slitting of the cell foam.

[0024] The present utility model will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model, and cannot be used to limit the protection scope of the present utility model.
[0025] The present utility model provides a Figures 1-5 core foam slitting device for adapting to a battery pack as shown in the figure, including a slitting plate 1, a lifting member 13 arranged directly above the slitting plate 1, and a square plate 14 installed at the bottom end of the lifting member 13 and capable of rotating 90 degrees and locking. Corner fixing mechanisms for corner abutting and fixing the core foam are provided at the four corners of the slitting plate 1. A slide plate 16 is slidably arranged at the bottom end of the square plate 14, and a slide seat 28 is slidably arranged at the bottom end of the slide plate 16, and the sliding directions of the slide plate 16 and the slide seat 28 are perpendicular. A cutting knife 18 for slitting the core foam is installed at the bottom end of the slide seat 28. Telescopic frames 20 capable of longitudinal expansion and contraction are installed in the middle of the four sides of the square plate 14. A side pressing roller 22 capable of abutting against the top end of the core foam is rotatably installed at the bottom end of the telescopic frame 20, and a spring 23 is sleeved on the telescopic frame 20. The lifting member 13 moves longitudinally up and down, so as to drive the cutting knife 18 to move down to the slitting position and slit the large-size core foam into small-size core foam;
[0026] When the cutting knife 18 is in the slitting position, the telescopic frame 20 is in a compressed state, and the side pressing roller 22 presses tightly against the top end of the core foam.
[0027] Side clamping seats 19 are detachably installed in the middle of the four sides of the square plate 14. The top end of the telescopic frame 20 is connected to the bottom surface of the side clamping seat 19. A mounting seat 21 is installed at the bottom end of the telescopic frame 20. The side pressing roller 22 is rotatably installed in the mounting seat 21. During the forced expansion and contraction process of the telescopic frame 20, the spring 23 is synchronously forced to be compressed. When the cutting knife 18 leaves the slitting position, the telescopic frame 20 resets under the drive of the spring 23.
[0028] At symmetric positions at the bottom end of the square plate 14, first slide rails 15 are installed. The sliding plate 16 can slide along the two first slide rails 15. At the bottom end of the sliding plate 16, a second slide rail 17 is installed. The sliding seat 28 can slide along the second slide rail 17, and the first slide rail 15 is perpendicular to the second slide rail 17. The driving force for the sliding plate 16 to slide along the first slide rail 15 and the driving force for the sliding seat 28 to slide along the second slide rail 17 can be driven by electricity, and the specific sliding distance is realized by programming.
[0029] At the bottom end of the slitting plate 1, a plurality of upright columns 2 are provided. Between the bottom ends of the plurality of upright columns 2, a U-shaped frame 3 is commonly installed. The lifting member 13 is detachably installed on the top of the U-shaped frame 3. On the one hand, the U-shaped frame 3 provides support for the slitting plate 1, and on the other hand, it can fix the position of the lifting member 13 directly above the slitting plate 1.
[0030] A connecting plate 24 is sleeved at the bottom end of the lifting part of the lifting member 13. At the end of the connecting plate 24, an arc-shaped chuck 25 is installed. At the top end of the square plate 14, a positioning stud 26 that can slide along the arc of the arc-shaped chuck 25 is installed. A nut 27 is threadedly sleeved on the part of the positioning stud 26 above the arc-shaped chuck 25. The maximum angle for the positioning stud 26 to slide within the arc-shaped chuck 25 is 90 degrees. When the positioning stud 26 slides along the arc from one side of the arc-shaped chuck 25 to the other side, the rotation angle of the square plate 14 is exactly 90 degrees.
[0031] At the four corners of the slitting plate 1, long slots 4 with one open end are opened. At the four corners of the slitting plate 1, sealing plates 5 that can close the open ends of the long slots 4 are abutted. A screw rod 7 is threadedly inserted into the sealing plate 5. At one end of the screw rod 7 located outside the slitting plate 1, a rotating frame 10 is installed. At one end of the screw rod 7 located inside the slitting plate 1, a plug post 9 is installed. At a suitable position inside the slitting plate 1, a jack 6 for the plug post 9 to rotate and insert is opened. The corner fixing mechanism includes a slider 8 threadedly sleeved on the screw rod 7 and capable of sliding along the long slot 4, and a folding abutting frame 12 detachably installed on the top end of the slider 8 through a mounting frame 11. By rotating the rotating frame 10 to drive the screw rod 7 to rotate, the slider 8 slides along the long slot 4 under the limitation of the long slot 4, and then drives the folding abutting frame 12 to slide towards or away from the center of the square plate 14, so as to abut and fix the cell foams of different sizes at their corner positions.
[0032] In the present utility model, the corner fixing structures at the four corners of the slitting plate 1 are used to abut and fix at the four corner positions of the large-sized cell foam. During the actual slitting process, the lifting member 13 moves vertically up and down, thereby driving the cutting knife 18 to move downward to the slitting position and slit the large-sized cell foam into small-sized cell foams. During the slitting process, through the sliding of the sliding plate 16 along the bottom end of the square plate 14 and the sliding of the sliding seat 28 along the bottom end of the sliding plate 16, and since the sliding direction of the sliding seat 28 is perpendicular to that of the sliding plate 16, the cutting knife 18 can perform a vertical movement within the plane at the bottom end of the square plate 14. At the same time, since the square plate 14 can rotate 90 degrees at the bottom end of the lifting member 13, the cutting knife 18 can perform a vertical movement cutting with different distance lengths within the plane, that is, the cell foam to be slit is adapted to different battery packs for use. During the process of the lifting member 13 moving vertically up and down and driving the cutting knife 18 to move downward to the slitting position, the side pressing rollers 22 first come into contact with the top end of the cell foam, and under the forced expansion and contraction of the telescopic frame 20 and the passive compression and limitation of the spring 23, when the cutting knife 18 reaches the slitting position, the side pressing rollers 22 are pressed tightly against the top end of the cell foam. Thus, during the slitting process of the cutting knife 18, the plurality of side pressing rollers 22 are used to press and fix near the slitting position, avoiding the wrinkles and corner warping near the slitting position of the cell foam caused by the shear stress of the cutting knife 18, which in turn affects the slitting of the next working station, that is, avoiding the problem that the slitting position is further compressed due to the existence of wrinkles and corner warping, and finally maximizing the utilization of the slitting of the cell foam.
[0033] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the technical principle of the present utility model, several improvements and deformations can still be made, and these improvements and deformations should also be regarded as the protection scope of the present utility model.
