Description

Technical Field

[0001] The present application relates to the field of battery processing technology, and in particular to a tape assembly and a feeding and cutting device. Background Art

[0002] Soft-pack battery designs mostly use rolls of high-temperature adhesive tape for protection. In the existing battery manufacturing process, rolls of high-temperature adhesive tape are loaded on the feeder tray and automatically cut to a certain length. Due to the high UPH (Units Per Hour) of the automatic line, the high-temperature adhesive tape is consumed quickly and requires frequent roll changes. Feeder material replacement is more complicated. Taking the bottom adhesive tape of moto LT02 (100 meters) as an example, the roll change time is about 5 minutes, 1 hour / time, and the total roll change time for one shift is 40 minutes, resulting in reduced production efficiency and cost transfer to the battery, resulting in increased costs and reduced battery competitiveness.

[0003] The existing solution is mainly to increase the winding length of the roll of high-temperature adhesive tape, but the increase in outer diameter caused by this method will make the winding force difficult to control. For example, insufficient winding force will produce bubbles inside the adhesive tape. Excessive winding force will lead to uneven force, deformation of the adhesive tape and a bowl shape.

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

In order to simplify the disclosure of the embodiments of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the embodiments of the present application. In addition, the embodiments of the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0030] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure.

[0031] In order to solve the problems in the prior art, the present application provides a tape assembly and a feeding and cutting device, which can effectively reduce the frequency of roll changing, thereby improving production efficiency and ensuring the yield rate.

[0032] Figure 1 A schematic cross-sectional structure diagram of an adhesive tape assembly provided in an embodiment of the present application is shown; Figure 2 A schematic structural diagram showing a side view of an adhesive tape assembly provided in an embodiment of the present application; Figure 3 A schematic cross-sectional structure diagram of another adhesive tape assembly provided in an embodiment of the present application is shown; Figure 4 A schematic diagram of the three-dimensional structure of an adhesive tape assembly provided in an embodiment of the present application is shown.

[0033] like Figure 1-4 As shown, an embodiment of the present application provides a tape assembly, including: a barrel 1 and tape 2, the tape 2 includes at least two roll units 21 wound around the outer circumferential surface of the barrel 1 and a connecting portion 22 connecting two adjacent roll units 21, the tail end of one of the two adjacent roll units 21 is connected to the connecting portion 22, and the head end of the other is connected to the connecting portion 22.

[0034] In the present application, two adjacent roll units 21 are connected by the connecting part 22 of the adhesive tape assembly. When one of the roll units 21 is used up on the automatic line, it can directly transition to the next roll unit 21 through the connecting part 22, thereby effectively reducing the frequency of roll replacement, thereby improving production efficiency and ensuring the yield rate.

[0035] In the related art, in order to increase the length of the adhesive tape assembly, it is generally achieved by increasing the number of rolls of adhesive tape, for example, extending 100 meters of adhesive tape to 150 meters or 200 meters. However, as the diameter of the roll of adhesive tape increases, the winding force will be difficult to control. If the winding force is insufficient, bubbles will be generated inside the adhesive tape; if the winding force is too large, the adhesive tape will be significantly deformed and take a bowl shape.

[0036] In the present application, by arranging multiple units 21 on the same barrel 1, the diameter of the unit 21 is not changed, so there will be no problem of winding force control caused by the increase in the diameter of the unit 21, and the total length of the adhesive tape 2 on a single barrel 1 can be greatly increased. By arranging a connecting portion 22 between two rolls of units 21 for effective transition, in the automated processing of batteries, after one roll of unit 21 is used up, it can directly transition to the next roll of unit 21, thereby solving the problem of production interruption caused by frequent roll changes on the automatic line and reducing the production cost of batteries.

[0037] In some embodiments, the outer peripheral surface of the barrel 1 is provided with a winding portion 11 and a transition portion 12 along its own axial direction, the unit 21 is wound around the winding portion 11, and the transition portion 12 is located between two adjacent winding portions 11 for accommodating the connecting portion 22 of the adhesive tape 2.

[0038] In the present application, the unit 21 is wound around the winding portion 11 of the barrel 1, and the connecting portion 22 of the adhesive tape 2 is accommodated through the transition portion 12 to prevent the connecting portion 22 of the adhesive tape 2 from being squeezed and deformed by the units 21 on both sides, thereby ensuring the transition effect of the connecting portion 22 on the units 21 on both sides.

[0039] Furthermore, the width of the winding portion 11 is equal to the width of the unit 21 .

[0040] In the present application, the width of the winding portion 11 is equal to the width of the unit 21, and the unit 21 can be just wound around the winding portion 11 of the barrel 1. Specifically, the unit 21 is tightly wound around the winding portion 11 of the barrel 1, and the unit 21 will not be deformed during transportation or placement due to its excessively large diameter, thereby ensuring the effect of the unit 21 in the later use, and can reduce the occupation of the axial space of the barrel 1 by the unit 21, so that enough units 21 can be placed on the barrel 1.

[0041] In some embodiments, the width of the transition portion 12 is greater than or equal to the width of the connecting portion 22 .

[0042] In the present application, since the connecting portion 22 of the adhesive tape 2 is also wound on the outer peripheral side of the barrel 1, by making the width of the transition portion 12 greater than or equal to the width of the unit 21, it is ensured that the connecting portion 22 of the adhesive tape 2 can be wound on the outer peripheral surface of the barrel 1, avoiding the connecting portion 22 of the adhesive tape 2 from bending and deforming in the transition portion 12, so that the connecting portion 22 of the adhesive tape 2 can be used directly later, or it is ensured that the connecting portion 22 can effectively transition between the two rolls of unit 21, avoiding the situation where the next roll of unit 21 cannot be fed normally due to wrinkles in the connecting portion 22.

[0043] In some embodiments, the width of the transition portion 12 is equal to the width of the connecting portion 22 .

[0044] In the present application, the connecting portion 22 of the adhesive tape 2 is equal to the width of the unit 21, and the width of the transition portion 12 is equal to the width of the unit 21, which can minimize the occupation of the connecting portion 22 of the adhesive tape 2 on the barrel 1. Moreover, the width of the transition portion 12 is equal to the width of the connecting portion 22, and the connecting portion 22 can also be limited by the units 21 on both sides, thereby ensuring the stability of the connecting portion 22 wrapped around the transition portion 12 of the barrel 1.

[0045] In a specific embodiment, the unit 21 is provided with two rolls, and the two roll units 21 are respectively arranged at two ends of the barrel 1 along the axial direction.

[0046] In the present application, two winding parts 11 and a transition part 12 are provided on the outer peripheral side of the barrel 1, and the transition part 12 is located between the two winding parts 11. The unit 21 is provided with two rolls. The two-roll unit 21 is respectively wound around the two winding parts 11 of the barrel 1 and is respectively located at the two ends of the barrel 1 along the axial direction. This can minimize the space occupied on the outer peripheral surface of the barrel 1, thereby reducing the size of the entire adhesive tape assembly, and will not affect the automatic line material tray 4.

[0047] Optionally, the unit 21 in the present application can also be 3 rolls, 4 rolls, etc., depending on the width and maximum load capacity of the automatic wire material tray 4.

[0048] In some embodiments, the axial length of the barrel 1 is three times the width of the unit 21. Specifically, the width of the unit 21 is L, and the axial length of the barrel 1 is 3L.

[0049] In the present application, the axial length of the barrel 1 is three times the width of the unit 21, and the two roll units 21 are respectively arranged at the two ends of the barrel 1, so that the space left between the two roll units 21 can just accommodate the connecting portion 22 of the adhesive tape 2, ensuring that the connecting portion 22 can be effectively wound and limited between the two roll units 21, thereby ensuring the effective transition of the connecting portion 22 to the units 21 on both sides.

[0050] In some embodiments, the material of the connection portion 22 is the same as that of the unit 21 .

[0051] In the present application, the material of the connecting portion 22 is the same as that of the unit 21, which not only facilitates the processing and molding of the adhesive tape assembly and reduces production costs, but the connecting portion 22 can not only connect and transition the two adjacent rolls of unit 21, but can also be directly used as unit 21 to ensure a smooth transition between the two rolls of unit 21, and there will be no need to re-search for the head end of the unit 21, thereby further improving production efficiency.

[0052] In some embodiments, the winding direction of the connecting portion 22 on the cartridge 1 is consistent with the winding direction of the unit 21 on the cartridge 1 .

[0053] In the present application, the winding direction of the connecting part 22 is consistent with the winding direction of the unit 21, ensuring that the connecting part 22 can be effectively wound and the stability of the connecting part 22 is ensured. Moreover, during the unwinding process, the barrel 1 always rotates in one direction to complete the unwinding, so that the unit 21 can always maintain a tensioned platform, ensuring the continuity and stability of the feeding of the unit 21.

[0054] The adhesive tape assembly connects two adjacent roll units 21 through the connecting portion 22 of the adhesive tape assembly. When one roll unit 21 is used up on the automatic line, it can directly transition to the next roll unit 21 through the connecting portion 22, thereby effectively reducing the frequency of roll changes, thereby improving production efficiency and ensuring the yield rate.

[0055] Figure 5 A schematic diagram of the three-dimensional structure of a feeding and cutting device provided in an embodiment of the present application is shown; Figure 6 Show Figure 5 A partial enlarged structural schematic diagram of the feeding and cutting device A is shown.

[0056] like Figure 5-6 As shown, an embodiment of the present application provides a feeding and cutting device, including: a frame 3; a material tray 4, which is arranged on the frame 3; the above-mentioned adhesive tape assembly, which is arranged on the material tray 4; a guide wheel group 5, which is arranged on the frame 3 and is used to guide the adhesive tape assembly on the material tray 4; and a cutting module 6, which is arranged on the frame 3 and is used to cut the adhesive tape assembly after being guided by the guide wheel group 5.

[0057] In the present application, the adhesive tape assembly is installed on the material tray 4, and the adhesive tape assembly is guided by the guide wheel group 5 and then transported to the die-cutting module. The correction of the unit 21 is completed in the guide wheel group 5, thereby ensuring that the die-cutting module will not deviate when cutting the unit 21 after changing the roll.

[0058] In some embodiments, the cutting module 6 includes a tongue depressing assembly 61, and the tongue depressing assembly 61 is used for the deviation-correcting adhesive tape assembly.

[0059] Specifically, the cutting module 6 also includes a roller 62, and the end of the unit 21 is attached to the roller 62, and the tongue 63 moves upward to press the roller 62 to prevent the roller 62 from rotating. Then the tongue pressing assembly 61 is released, and the cutting module 6 moves in a straight line for a distance. The tongue pressing assembly 61 presses the unit 21, and the cutter 64 moves upward to cut off the unit 21. After the material taking module takes away the product, the cutter 64 and the tongue 63 return to their original positions, and the cutting module 6 returns synchronously. The adhesive tape assembly is pulled by the tongue pressing assembly 61, so that the new end of the unit 21 after cutting is pasted on the roller 62 again, and the above steps are repeated to complete the cutting of the unit 21.

[0060] When one roll of unit 21 is used up and transitioned to another roll of unit 21, the unit 21 discharged from the barrel 1 will form an angle with the cutting module 6. Since the distance from the barrel 1 to the cutting module 6 is one meter, and the movement of the cutting module 6 is a linear motion, the tongue depressor assembly 61 will also play a role in limiting and correcting the unit 21, so the cutter 64 will not tilt the cut shape, thereby ensuring the cutting quality of the unit 21.
