In the process of making battery strings, welding tapes are needed to connect the upper and lower surfaces of two adjacent battery cells. Usually, the welding tapes are fixed to the battery cells by using adhesive tapes.

[0047] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0048] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0050] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0051] In the process of making battery strings, it is necessary to use welding tape to connect the upper and lower surfaces of two adjacent battery cells. Usually, the welding tape is fixed on the battery cell by using adhesive tape to fix the welding tape. Since there are many welding tapes on the battery cell, multiple adhesive tapes are also required to fix the welding tapes separately. In order to simplify the replacement action and improve the production rhythm, it is usually adopted to cut a roll of adhesive tape into the required number of strips and then supply them to the battery cell. When the commonly used slitting mechanism is used, because the adhesive tape has great elasticity, the adhesive tape is prone to shaking when being cut by the slitting knife, resulting in the edge of the tape after cutting to be corrugated or jagged, affecting the normal use of the tape.

[0052] In order to solve the above problems, Figure 1-Figure 4 As shown, the present embodiment provides a tape slitting device, which includes a feed shaft 1, a tape threading mechanism 3 and a slitting mechanism 4. A plurality of feed trays 2 are rotatably arranged on the feed shaft 1. The feed trays 2 are wound with tape. The tape pulled out from the feed trays 2 passes through the tape threading mechanism 3. The tape threading mechanism 3 can clamp the tape. The slitting mechanism 4 is located on the downstream side of the tape threading mechanism 3. The slitting mechanism 4 has a guide surface 4211. The blade 41 protrudes from the guide surface 4211. The tape segment on the guide surface 4211 can be adsorbed. The blade 41 can slit the tape to form a plurality of slit tapes.

[0053] The tape threading mechanism 3 is located on the upstream side of the slitting mechanism 4. The tape passes through the tape threading mechanism 3 and is clamped by the tape threading mechanism 3. The tape threading mechanism 3 can ensure that the tape maintains a stable path, reduce the vibration or swing of the tape during transmission, and to a certain extent reduce the possibility of jitter during tape slitting; the guide surface 4211 of the slitting mechanism 4 can stably support the tape so that the tape can slide smoothly on the guide surface 4211, and the tape segment on the guide surface 4211 can be adsorbed. When the tape is cut into multiple slitting tapes by the blade 41 protruding from the guide surface 4211, since the tape is adsorbed on the guide surface 4211 by the slitting mechanism 4, under the action of the adsorption force, the tape will remain stable and flat, and will not produce wrinkles or distortions due to relaxation, nor will it produce jitter or fluctuations, thereby ensuring the stability of the slitting process, reducing the slitting error caused by the jitter of the tape, and making the slitting operation more accurate and reliable. The tape slitting device has a simple structural design and can prevent the tape from shaking during the slitting process, thereby ensuring that the edges of the slit tape are smooth and ensuring its subsequent normal use.

[0054] Specifically, Figure 1 , Figure 2As shown, the slitting mechanism 4 includes a plurality of slitting components 42, which slit a plurality of tapes pulled out from a plurality of feed trays 2 one by one, and the slitting components 42 include at least two mounting plates 421 spaced apart along the width direction of the tape, a guide surface 4211 is provided on the side of the mounting plate 421 facing the tape, a blade 41 is sandwiched between two adjacent mounting plates 421, an adsorption chamber is provided inside the mounting plate 421, an adsorption port 42111 is provided on the guide surface 4211, the adsorption port 42111 is communicated with the adsorption chamber, and a vacuum generator is connected to the adsorption chamber.

[0055] Each tape pulled out from the feed tray 2 corresponds to a slitting assembly 42, which can realize slitting of multiple tapes at the same time, greatly improving production efficiency; by setting a mounting plate 421, the blade 41 is clamped between two mounting plates 421, thereby ensuring the stability and accuracy of the blade 41 during the slitting process, and reducing the possibility of deviation or shaking of the blade 41; the adsorption port 42111 is connected to the adsorption chamber, and the adsorption chamber is connected to a vacuum generator. The vacuum generator is used to form a local negative pressure area at the adsorption port 42111 to adsorb the tape segment located on the guide surface 4211.

[0056] In this embodiment, if Figure 2 As shown, the guide surface 4211 is an arc surface. The design of the arc surface makes the adhesive tape slide more smoothly on the mounting plate 421, ensuring that there are no sharp edges and corners on the sliding path of the adhesive tape, and thus the adhesive tape will not be damaged.

[0057] It is understandable that the number of mounting plates 421 and blades 41 is determined according to actual needs. Figure 2 As shown, in this embodiment, one tape needs to be cut into five strips, so the number of blades 41 is four, and the number of mounting plates 421 is five.

[0058] Specifically, the blade 41 is made of ceramic or tungsten steel, both of which have high hardness, and can maintain high precision and stability when slitting the tape, thereby reducing errors caused by wear of the blade 41 .

[0059] Specifically, Figure 1 , Figure 3 As shown, the tape threading mechanism 3 includes a shaft assembly 31, and the shaft assembly 31 includes two shafts 311. The distance between the two shafts 311 is adjustable, and the tape is threaded between the two shafts 311. When threading the tape, first adjust the two shafts 311 to increase the distance between the two shafts. At this time, the tape can be threaded conveniently and quickly, and then adjust the distance between the two shafts 311 so that the two shafts clamp the tape. The distance between the two shafts is determined according to the thickness of the tape and the required clamping force. By setting the distance between the shafts 311 to be adjustable, it is more convenient to pass the tape, and the tape threading mechanism 3 can clamp tapes of different thicknesses and requiring different clamping forces, and has strong versatility.

[0060] For more details, see Figure 1 , Figure 3 The belt threading mechanism 3 further includes two mounting seats 32 and a locking member (not shown in the figure). The two mounting seats 32 are respectively arranged at the two ends of the shaft assembly 31. Two mounting holes 321 are provided on the mounting seats 32. The ends of the two shafts 311 are respectively inserted into the two mounting holes 321, and at least one shaft 311 can slide in the mounting holes 321 to approach or move away from the other shaft 311; the locking member is inserted into the mounting holes 321 and the shaft 311 to fix the shaft 311 to the mounting seats 32. When adjusting the distance between the two shafts 311, the locking member is screwed to allow at least one shaft 311 to move freely. After sliding the shaft 311 to a suitable position, the locking member is re-inserted and screwed to fix the shaft 311.

[0061] In this embodiment, at least one mounting hole 321 is a waist-shaped hole. In this case, the shaft rod 311 can slide along the length direction of the waist-shaped hole to change the distance between the two shaft rods 311 .

[0062] In this embodiment, if Figure 1 , Figure 3 As shown, the belt threading mechanism 3 also includes a plurality of first annular bodies 33 and a plurality of second annular bodies 34. The plurality of first annular bodies 33 are rotatably sleeved on a shaft rod 311 in one direction through a first one-way bearing. The plurality of first annular bodies 33 are arranged at intervals. The plurality of second annular bodies 34 are rotatably sleeved on another shaft rod 311 in one direction through a second one-way bearing. The plurality of second annular bodies 34 are arranged at intervals. The plurality of first annular bodies 33 and the plurality of second annular bodies 34 correspond to each other to form a plurality of annular body groups. The plurality of adhesive tapes are threaded through the plurality of annular body groups one by one so that the first annular bodies 33 and the second annular bodies 34 clamp the corresponding adhesive tapes. By setting up the annular body group, the belt can drive the annular body group to rotate when it is transported forward. At this time, the friction between the belt and the annular body group is sliding friction, the friction force is small, the wear on the belt is also small, and the transmission efficiency can be improved, which helps to reduce the overall energy consumption; the setting of the first one-way bearing and the second one-way bearing enables the first annular body 33 and the second annular body 34 to rotate only in one direction, thereby preventing the belt from retreating due to the reverse rotation of the first annular body 33 and the second annular body 34 (taking the direction of the first annular body 33 and the second annular body 34 as positive when the belt moves forward).

[0063] Specifically, Figure 3 As shown, the first annular body 33 or the second annular body 34 is provided with a first guide groove 35 along its circumference, and the adhesive tape is located in the first guide groove 35. The first guide groove 35 provides a clear path for the adhesive tape, ensuring that the adhesive tape can be conveyed on the tape threading mechanism 3 according to a predetermined track, so that the adhesive tape runs more stably.

[0064] In an optional embodiment, if Figure 1 As shown, the tape slitting device also includes a plurality of damping pressure rods 7, which are located one by one above the plurality of feeding trays 2, and the damping pressure rods 7 are pressed on the tape. The damping pressure rods 7 can provide a certain damping when the tape is pulled out to prevent the tape from being pulled out excessively.

[0065] Specifically, Figure 1 , Figure 4 As shown, the tape slitting device also includes a differential roller 5, which is located at the downstream side of the slitting mechanism 4, and is provided with a plurality of second guide grooves 51 extending along its circumference. The plurality of second guide grooves 51 are arranged at intervals along the circumference of the differential roller 5, and the plurality of slitting tapes are located one by one in the plurality of second guide grooves 51, and the bottoms of two adjacent second guide grooves 51 are located on different horizontal lines. The plurality of second guide grooves 51 on the differential roller 5 provide stable guidance for the plurality of slitting tapes, which helps to reduce the swing and deviation of the slitting tapes during the transmission process, and the bottoms of two adjacent second guide grooves 51 are located on different horizontal lines. This design enables the differential roller 5 to perform layered positioning on two adjacent slitting tapes, so that the adjacent slitting tapes are effectively separated to avoid sticking between the slitting tapes.

[0066] Specifically, Figure 1 As shown, the tape slitting device also includes a plurality of spacing rollers 6, all of which are located on the downstream side of the slitting mechanism 4 and are distributed on the conveying path of the slitting tape to guide the slitting tape. The spacing rollers 6 are provided with a plurality of third guide grooves 61 extending along their circumferences. The plurality of third guide grooves 61 are arranged at intervals along the axial direction of the spacing rollers 6. The distance between two adjacent third guide grooves 61 is x1. The plurality of slitting tapes are located one by one in the plurality of third guide grooves 61. Among the two adjacent spacing rollers 6, the x1 of the downstream spacing roller 6 is greater than the x1 of the upstream spacing roller 6.

[0067] The third guide groove 61 provides a clear path for the slitting belt, ensuring that the slitting belt can be transported on the spacing roller 6 according to the predetermined track; between two adjacent spacing rollers 6, the x1 of the spacing roller 6 located downstream is greater than the x1 of the spacing roller 6 located upstream, that is, along the transportation direction of the slitting belt, the x1 on each spacing roller 6 is gradually increasing, that is, the slitting belt will gradually disperse during the transportation process to achieve the spacing of the slitting belt. Compared with directly spacing the slitting belt across a large angle, this gradual spacing method can reduce the occurrence of tilting or deformation of the slitting belt.

[0068] Specifically, Figure 1 As shown, the tape slitting device further comprises a mounting frame 8, and all the above-mentioned structures are mounted on the mounting frame 8.

[0069] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
