Description

TECHNICAL FIELD

[0001] The present application relates to the field of battery production, in particular to a strip material cutting device and a film strip attaching device. BACKGROUND

[0002] When cutting strip material (such as solder strip, film strip), it is usually necessary to set a clamping feeding mechanism and a traction mechanism on the front and rear sides of the cutting device respectively. After cutting off the strip material each time, the end of the strip material in the feeding direction is sent out of the cutting knife by the clamping feeding mechanism, so as to facilitate the traction mechanism to pull out the strip material to a predetermined length, and the cutting device is used to cut off the strip material again. The setting of the clamping feeding mechanism increases the cost and structural complexity of the device. SUMMARY

[0003] In view of the above technical problems existing in the traditional cutting device, the present application provides a strip material cutting device, and the technical scheme is as follows:

[0004] A strip material cutting device, comprising a base, a mounting frame, a pressing mechanism and a cutting mechanism, wherein:

[0005] The mounting frame is arranged on the base, and a plurality of material channels are arranged on the mounting frame and extend from a first side wall of the mounting frame to a second side wall of the mounting frame;

[0006] The pressing mechanism is arranged on the first side wall of the mounting frame;

[0007] The cutting mechanism is arranged on the second side wall of the mounting frame, and a cutting member of the cutting mechanism is arranged to maintain a predetermined distance from the exit end of the material channel;

[0008] A plurality of strip materials pass through the pressing mechanism along a first horizontal direction and then pass through the corresponding material channel to the second side of the mounting frame;

[0009] The pressing mechanism is used to press the strip material, and the cutting mechanism is used to cut off the strip material by the cutting member to obtain a strip material segment of a predetermined length.

[0010] Since the material channel and the cutting member of the cutting mechanism maintain a predetermined distance, after the cutting mechanism cuts off the strip material, the cut end of the strip material extends outward from the material channel. In this way, the traction mechanism can again clamp the cut end of the strip material to pull the strip material before the next cutting is performed. It can be seen that the strip material cutting device provided by the present application does not need to use the clamping feeding mechanism to feed the strip material, so it can reduce the cost and structural complexity of the device.

[0011] In some embodiments, the pressing mechanism comprises a pressing plate, a cushion plate and a cushion plate driving part, wherein: the pressing plate is fixedly installed on the first side wall of the mounting frame; the cushion plate driving part is arranged on the mounting frame; the cushion plate is connected to the driving end of the cushion plate driving part and arranged opposite to the pressing plate in an up-down direction, the strip-shaped material passes between the pressing plate and the cushion plate, and the cushion plate driving part is used to drive the cushion plate to move towards or away from the pressing plate to press or release the strip-shaped material.

[0012] Through the cooperation of the pressing plate and the cushion plate, the pressing mechanism realizes the pressing and releasing of the strip-shaped material passing between the pressing plate and the cushion plate.

[0018] After the strip-shaped material is pressed by the pressing mechanism, the strip-shaped material in the material channel is adsorbed by the suction block, and the strip-shaped material to be cut is stretched out of the material channel outlet, so that the strip-shaped material to be cut can be prevented from drooping.

[0019] In some embodiments, the cutting mechanism comprises at least one cutting assembly, the cutting assembly comprising a cutter holder, a cutter holder driving mechanism and a plurality of cutting pieces, wherein: the cutter holder driving mechanism is arranged on the mounting frame; the cutter holder is slidingly connected to the second side wall of the mounting frame and connected to the driving end of the cutter holder driving mechanism; the plurality of cutting pieces are arranged side by side on the cutter holder along the second horizontal direction, each cutting piece corresponding to a material passage and being used to cut the strip material passing through the corresponding material passage, wherein the second horizontal direction is perpendicular to the first horizontal direction; the cutter holder driving mechanism is used to drive the cutter holder to slide on the mounting frame along the second horizontal direction, so as to drive the cutting pieces to move between the avoiding positions and the cutting positions; when the cutting piece moves to the corresponding cutting position, the cutting piece is aligned with the corresponding material passage and a predetermined gap is formed between the cutting piece and the outlet of the material passage; when the cutting piece moves to the corresponding avoiding position, the cutting piece is offset from the corresponding material passage.

[0020] By arranging the cutting mechanism, the plurality of cutting pieces can be driven by the cutter holder driving mechanism to move synchronously between the avoiding positions and the cutting positions, and when each cutting piece moves to the corresponding cutting position, the cutting piece is aligned with the corresponding material passage, thereby implementing synchronous cutting of all strip materials, and when each cutting piece moves to the corresponding avoiding position, the material passage is exposed, thereby enabling the traction mechanism to smoothly clamp the cut end of the strip material from each material passage to implement traction of the strip material before the next cutting is performed.

[0021] In some embodiments, the cutting mechanism further comprises a first limiting piece, which is arranged on the mounting frame and located at one side of the cutter holder; the cutter holder comprises a first sliding plate and a second sliding plate, wherein: the first sliding plate is slidingly connected to the second side wall of the mounting frame and connected to the driving end of the cutter holder driving mechanism, the cutter holder driving mechanism drives the first sliding plate to slide on the mounting frame in the second horizontal direction, a plurality of groups of waist-shaped holes are arranged on the first sliding plate, each group of waist-shaped holes comprises a first waist-shaped hole and a second waist-shaped hole arranged symmetrically above and below, a included angle smaller than 90° is formed between the first waist-shaped hole and the second waist-shaped hole, and the included angle opening faces the first limiting piece; the second sliding plate is slidingly connected to the first sliding plate and can slide on the first sliding plate in the second horizontal direction; the cutting piece is a scissors, wherein the rotation axis of the scissors is connected to the second sliding plate, the first tail end of the scissors is slidingly connected in the first waist-shaped hole and can slide in the first waist-shaped hole, the second tail end of the scissors is slidingly connected in the second waist-shaped hole and can slide in the second waist-shaped hole, and the cutting end of the scissors faces the first limiting piece; when the first sliding plate slides towards the first limiting piece to the first position, the second sliding plate abuts against the first limiting piece, and the cutting end of each scissors reaches the corresponding cutting position; when the first sliding plate continues to slide towards the first limiting piece to the second position, the first tail end and the second tail end of the scissors slide close to each other under the guidance of the first waist-shaped hole and the second waist-shaped hole, so as to drive the cutting end of the scissors to cut the strip-shaped material passing through the corresponding material channel.

[0022] By arranging the first limiting piece and by arranging the specific structure of the cutter holder, the cutter holder is driven to slide by the cutter holder driving mechanism, so as to drive the cutting piece to the corresponding cutting position and to drive the cutting piece to perform the cutting action. That is, the cutter holder driving mechanism not only realizes the translation driving of the cutting piece, but also realizes the cutting driving of the cutting piece, thereby further reducing the complexity of the equipment.

[0023] In some embodiments, the cutting mechanism further comprises a second limiting piece, which is arranged on the mounting frame and located at the same side of the cutter holder as the first limiting piece; when the first sliding plate continues to slide towards the first limiting piece to the second position, the first sliding plate abuts against the second limiting piece.

[0028] By providing the translation driving mechanism, the mounting frame can be driven to slide on the base, so that the mounting frame and the pressing mechanism and the cutting mechanism thereon can avoid the traction mechanism. By providing the translation driving mechanism in the form of a scissor linkage, the actual driving stroke of the translation driving cylinder is extended, and the sliding range of the mounting frame is increased.

[0063] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below in combination with the drawings and specific embodiments.

[0064] When cutting a strip-shaped material (such as a welding strip, a film strip), it is usually necessary to respectively set a clamping feeding mechanism and a traction mechanism on the front and rear sides of the cutting device. After cutting off the strip-shaped material each time, the end of the strip-shaped material in the feeding direction is sent out of the cutting knife by the clamping feeding mechanism, so as to facilitate the traction mechanism to pull out the strip-shaped material to a predetermined length, and the cutting device is used to implement the cutting-off processing again. The setting of the clamping feeding mechanism increases the cost and structural complexity of the equipment.

[0065] In view of the above technical problems existing in the traditional cutting device, the present application provides a strip-shaped material cutting device. By using the strip-shaped material cutting device, the clamping feeding mechanism is no longer needed to send out the strip-shaped material, so that the cost and structural complexity of the equipment can be reduced.

[0066] As shown in Figure 1 The strip-shaped material cutting device provided by the embodiment of the present application comprises a base 1, a mounting frame 2, a pressing mechanism 3 and a cutting mechanism 4, wherein:

[0067] The mounting frame 2 is arranged on the base 1, and the mounting frame 2 is provided with a plurality of material channels penetrating from the first side wall (such as the left side wall) of the mounting frame to the second side wall (such as the right side wall) of the mounting frame.

[0068] The pressing mechanism 3 is arranged on the first side wall of the mounting frame 2.

[0069] The cutting mechanism 4 is installed on the second side wall of the mounting frame, and the cutting part of the cutting mechanism 4 maintains a predetermined distance from the exit end of the material channel.

[0070] Several strips of material along the first horizontal direction (e.g.) Figure 1 After passing through the clamping mechanism 3 in the X-axis direction, they pass through the corresponding material channel to the second side of the mounting frame.

[0071] The clamping mechanism 3 is used to clamp the strip material, and the cutting mechanism 4 is used to cut the strip material through the cutting piece to obtain a strip material segment of a predetermined length.

[0072] As can be seen, because a predetermined distance is maintained between the material channel and the cutting element of the cutting mechanism 4 along the first horizontal direction, the cutting mechanism 4 does not perform the cutting action directly against the outlet of the material channel. Therefore, after the cutting mechanism 4 cuts the strip material, the cut end of the strip material still extends out of the material channel outlet and is suspended in the air. This ensures that the traction mechanism can smoothly clamp the cut end of the strip material to pull the strip material before performing the next cut. Using the strip material cutting device provided in this application, there is no need to use a clamping and feeding mechanism to feed the strip material out, thus reducing the cost and structural complexity of the equipment.

[0073] The strip material cutting device provided in this application embodiment is suitable for cutting strip materials such as film strips and welding strips.

[0074] like Figure 2 As shown, optionally, the clamping mechanism 3 includes a pressure plate 31, a pad 32, and a pad driving part 33, wherein: the pressure plate 31 is fixedly installed on the first side wall of the mounting frame 2. The pad driving part 33 is disposed on the mounting frame 2. The pad 32 is connected to the driving end of the pad driving part 33 and is arranged vertically opposite to the pressure plate 31. The strip material passes between the pressure plate 31 and the pad 32. The pad driving part 33 drives the pad 32 to move up or down toward or away from the pressure plate 31, thereby clamping or releasing the strip material.

[0075] Figure 2 In the illustrated embodiment, the pad 32 is located below the pressure plate 31. The pad driving unit 33 includes two lifting drive cylinders arranged in pairs on both sides of the mounting frame 2. Both ends of the pad 32 are respectively connected to one of the lifting drive cylinders. When the two lifting drive cylinders synchronously drive the pad 32 to rise, they compress the strip material; when the two lifting drive cylinders synchronously drive the pad 32 to fall, they release the strip material. Of course, in some alternative embodiments, the pad 32 may also be positioned above the pressure plate 31.

[0076] Optionally, the clamping mechanism 3 further includes several second horizontal directions perpendicular to the first horizontal direction (e.g., ...). Figure 2The elastic pressing rods 34 are arranged side by side on the pressing plate 31 in the Y-axis direction of the X-Y coordinate system. When the cushion plate 32 is driven to move towards the pressing plate 31, each elastic pressing rod 34 is used to elastically press a strip material on the cushion plate 32, so that all the strip materials can be pressed. Optionally, an anti-sticking layer is arranged on the side of the cushion plate 32 which is in contact with the strip materials, so as to prevent the pressed strip materials from being adhered to the cushion plate 32.

[0077] Continuing to refer to Figure 2 As shown in the drawings, the pressing mechanism 3 further comprises a guide rod 35, wherein the guide rod 35 passes through the cushion plate 32, one end of the guide rod 35 is connected to the pressing plate 31, and the other end of the guide rod 35 is connected to the mounting frame 2. The cushion plate driving part 33 drives the cushion plate 32 to ascend and descend along the guide rod 35. By arranging the guide rod 35, the ascending and descending of the cushion plate 32 is guided, and the deviation of the cushion plate 32 is prevented.

[0078] As shown in the drawings, Figures 3 to 5 Optionally, a plurality of guide-out assemblies 5 are arranged on the mounting frame 2, each guide-out assembly 5 comprises a support block 51 and an adsorption block 52, wherein the support block 51 is provided with a material channel 53 as described above, and the adsorption block 52 is arranged above the support block 51 and is used to adsorb the strip material in the material channel 53.

[0079] After the part of the strip material in the pressing mechanism 3 is pressed by the pressing mechanism 3, the strip material in the material channel is adsorbed by the adsorption block 52, and the strip material to be cut is extended out of the outlet of the material channel 53. In this way, the strip material to be cut is prevented from drooping and causing the cutting mechanism 4 to fail to smoothly implement the cutting operation.

[0080] As shown in the drawings, Figures 3 to 4 The cutting mechanism 4 comprises two cutting assemblies which are symmetrically arranged on the mounting frame 2 along the second horizontal direction, and the two cutting assemblies synchronously implement the cutting operation on the strip material. By arranging two cutting assemblies, the cutting members can be evenly arranged on the two cutting assemblies, so as to shorten the length of each cutting assembly, and finally reduce the load of the driving part of the cutting assembly, so that the cutting assembly can be more smoothly moved and implement the cutting operation.

[0081] Of course, only one cutting assembly can be arranged, and all the cutting members are arranged in the cutting assembly.

[0082] Since the structures and cutting principles of the two cutting assemblies are the same, only the cutting assembly on one side (for example, the right side) will be taken as an example to describe the structure and cutting principle of the cutting assembly.

[0083] As shown in the drawings, Figure 3 , Figure 4 , Figure 6 andFigure 7 As shown in the figure, the cutting assembly comprises a cutter holder 41, a cutter holder driving mechanism 42 and a plurality of cutting members 43, wherein: the cutter holder driving mechanism 42 is arranged on the mounting frame 2. The cutter holder 41 is slidingly connected to the second side wall of the mounting frame 2 and connected to the driving end of the cutter holder driving mechanism 42. The plurality of cutting members 43 are arranged side by side on the cutter holder 41 along the second horizontal direction (such as the Y-axis direction in the figure), each cutting member 43 corresponds to a material passage 53, and is respectively used to cut off the strip material passing out from the corresponding material passage 53. The cutter holder driving mechanism 42 is used to drive the cutter holder 41 to slide on the mounting frame 2 along the second horizontal direction, so as to drive each cutting member 43 to move between the respective avoiding position and the cutting position.

[0084] When the cutting member 43 moves to the corresponding cutting position, the cutting member 43 is aligned with the corresponding material passage 53, and a predetermined size gap is formed between the cutting member 43 and the outlet of the material passage 53. At this time, the cutting member 43 can implement the cutting operation on the strip material passing out from the corresponding material passage 53.

[0085] After completing the cutting operation on the strip material, when the cutting member 43 moves to the corresponding avoiding position, the cutting member 43 is offset from the corresponding material passage 53. At this time, the traction mechanism can clamp the cut end of the strip material extending from the material passage 53 to implement the traction of the strip material before the next cutting is performed.

[0086] As shown in the figure, optionally, the cutting mechanism 4 further comprises a first limiting member 44 arranged on the mounting frame 2 and located at one side (such as the left side in the figure) of the cutter holder 41. Figures 3 to 4

[0087] The cutter holder 41 comprises a first sliding plate 411 and a second sliding plate 412, wherein: the first sliding plate 411 is slidingly connected to the second side wall of the mounting frame 2 and connected to the driving end of the cutter holder driving mechanism 42, the cutter holder driving mechanism 42 drives the first sliding plate 411 to slide on the mounting frame 2 along the second horizontal direction, and a plurality of groups of waist-shaped holes are arranged on the first sliding plate 411, each group of waist-shaped holes comprises a first waist-shaped hole 413 and a second waist-shaped hole 414 arranged symmetrically upward and downward, a included angle smaller than 90° is formed between the first waist-shaped hole 413 and the second waist-shaped hole 414, and the included angle opening faces the first limiting member 44. The second sliding plate 412 is slidingly connected to the first sliding plate 411 and can slide on the first sliding plate 411 along the second horizontal direction.

[0088] ​The cutting member 43 is a scissors, wherein a rotating shaft of the scissors is connected to the second sliding plate 412, a first tail end of the scissors is slidingly connected in the first waist-shaped hole 413 and can slide along the first waist-shaped hole 413, a second tail end of the scissors is slidingly connected in the second waist-shaped hole 414 and can slide along the second waist-shaped hole 414, and a cutting end of the scissors faces the first limiting member 44. Optionally, the first tail end and the second tail end of the scissors are both provided with a roller, the roller on the first tail end of the scissors is located in the first waist-shaped hole 413 and can roll in the first waist-shaped hole 413, and the roller on the second tail end of the scissors is located in the second waist-shaped hole 414 and can roll in the second waist-shaped hole 414.

[0089] Optionally, a spring 46 is further arranged between the first sliding plate 411 and the second sliding plate 412, and the spring 46 tends to pull the second sliding plate 412, so that the cutting end of the scissors is in an open state.

[0090] The specific cutting process of the cutting mechanism 4 is as follows:

[0091] In the initial state, the first sliding plate 411 is away from the first limiting member 44, and each scissors is in an avoiding position, and each scissors is misaligned with the corresponding material channel 53.

[0092] When the cutting operation needs to be performed, the knife holder driving mechanism 42 first drives the first sliding plate 411 to slide towards the first limiting member 44 to the first position, so that the second sliding plate 412 abuts against the first limiting member 44, and the cutting end of each scissors reaches the corresponding cutting position.

[0093] The knife holder driving mechanism 42 continues to drive the first sliding plate 411 to slide towards the first limiting member 44 to the second position, and in this process, since the second sliding plate 412 is abutted by the first limiting member 44, a relative displacement is generated between the first sliding plate 411 and the second sliding plate 412. The first tail end and the second tail end of each scissors are pressed and slide close under the guidance of the first waist-shaped hole 413 and the second waist-shaped hole 414, so as to drive the cutting end of the scissors to close, thereby cutting the strip-shaped material passing out from the corresponding material channel.

[0094] After the cutting operation is completed, the knife holder driving mechanism 42 drives the first sliding plate 411 to slide away from the first limiting member 44 to reset, so that each scissors returns to the initial avoiding position, and at the same time, the spring 46 is reset under pressure, so as to drive the second sliding plate 412 to slide relative to the first sliding plate 411 to reset, and the cutting end of each scissors returns to the open state.

[0095] It can be seen that by setting the first limiting member 44 and by setting the structure of the tool rest 41 as described above, the tool rest driving mechanism 42 can drive the second sliding plate 412 to slide, thereby enabling the cutting member 43 to switch between the cutting position and the avoiding position and enabling the cutting member 43 to perform the cutting action. That is, the tool rest driving mechanism 42 not only enables the translation driving of the cutting member 43 but also enables the cutting driving of the cutting member 43, thereby further reducing the complexity of the equipment.

[0096] Optionally, the cutting mechanism 4 further comprises a second limiting member 45, which is arranged on the mounting frame 2 and located on the same side of the tool rest as the first limiting member 44. When the first sliding plate 411 continues to slide towards the first limiting member 44 to the second position, the first sliding plate 411 finally abuts against the second limiting member 45.

[0097] By setting the second limiting member 45, the sliding of the first sliding plate 411 is limited, thereby preventing the first sliding plate 411 from sliding too much and damaging the cutting member 43.

[0098] As shown in FIGS. Figure 1 and Figures 8 to 10 The base 1 is provided with a first sliding rail 6 and a second sliding rail 7 extending along a first horizontal direction, and the mounting frame 2 is slidingly connected to the first sliding rail 6. Correspondingly, the strip material cutting device in the embodiment of the present application further comprises a translation driving mechanism 8. The translation driving mechanism 8 comprises a translation driving cylinder 81, a sliding block 82 and a scissor linkage 83, wherein: the translation driving cylinder 81 is mounted on the base 1, the sliding block 82 is slidingly connected to the second sliding rail 7 and connected to the driving end of the translation driving cylinder 81, and the translation driving cylinder 81 is used to drive the sliding block 82 to slide along the second sliding rail 7. The scissor linkage 83 is connected to the sliding block 82, one end of the scissor linkage 83 extends out of the sliding block 82 and is hinged to the base 1, and the other end of the scissor linkage 83 extends out of the sliding block 82 and is hinged to the mounting frame 2.

[0099] When the translation driving cylinder 81 drives the sliding block 82 to slide along the second sliding rail 7, the scissor linkage 83 is driven to extend and retract, thereby pushing the mounting frame 2 to slide along the first sliding rail 6.

[0100] By setting the translation driving mechanism 8, the mounting frame 2 can be driven to slide on the base 1, thereby enabling the mounting frame 2 and the pressing mechanism 3 and the cutting mechanism 4 thereon to avoid the traction mechanism. By setting the translation driving mechanism 8 as a scissor driving structure, the driving stroke of the translation driving cylinder 81 is lengthened, and the sliding range of the mounting frame 2 is increased.

[0101] The present application also provides a film strip attaching device, which comprises a rack and a film strip feeding device, a film strip traction device, a film strip suction device and any one of the strip material cutting devices provided in the above embodiments arranged on the rack.
