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.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] In order to solve the above problems, Figure 1-Figure 3 As shown, the present embodiment provides a tape slitting device, which includes a feed shaft 1, a slitting mechanism 3, a first adsorption member and a second adsorption member. A plurality of feed trays 2 are rotatably arranged on the feed shaft 1, on which tape is rolled, and the slitting mechanism 3 is configured to slit the tape to form a plurality of slitting tapes. Along the pull-out direction of the tape, the upstream side and the downstream side of the slitting mechanism 3 are respectively provided with a first adsorption member and a second adsorption member, and the portion of the tape located between the first adsorption member and the second adsorption member is a slitting section. The first adsorption member can adsorb the tape section located thereon, and the second adsorption member can adsorb the tape section located thereon, and the second adsorption member can drive the slitting tape to be transported downstream to tension the slitting section.

[0047] The first adsorption member and the second adsorption member work together to respectively adsorb and fix the two ends of the slitting section of the adhesive tape, and the second adsorption member can drive the slitting tape to be transported downstream, so that the slitting section always remains in a tensioned state, and can maintain the flatness of the slitting section, reduce wrinkles or distortions caused by loose slitting sections, ensure stability during the slitting process, reduce slitting errors caused by tape shaking, and make the slitting operation more accurate and reliable. The structural design of this tape slitting device is simple, which can prevent the tape from shaking during the slitting process, ensure the flatness of the edges of the slitting tape, and ensure its subsequent normal use.

[0048] In some embodiments, Figure 1 As shown, there are multiple supply trays 2, and multiple supply trays 2 supply materials simultaneously, that is, multiple tapes are cut at the same time, which improves the cutting efficiency, optimizes the production process, and speeds up the production rhythm.

[0049] Specifically, Figure 1 As shown, the first adsorption member is an adsorption disk 4, and a plurality of first adsorption hole groups 41 are provided on the adsorption disk 4. The tape segments of the plurality of adhesive tapes pulled out by the plurality of feed disks 2 and located on the adsorption disk 4 correspond to the plurality of first adsorption hole groups 41. That is, each tape segment located on the adsorption disk 4 corresponds to a group of first adsorption hole groups 41. The first adsorption hole groups 41 can form a local negative pressure area to adsorb the tape segment located thereon, so that the cut segments of the adhesive tape can remain stable.

[0050] In this embodiment, a group of first adsorption holes 41 includes a plurality of first adsorption holes, and the plurality of first adsorption holes can evenly distribute the adsorption force on the tape segment, ensuring that the tape segment can be stably adsorbed over the entire width or length, and if one or a few of the first adsorption holes are blocked or fail, the remaining first adsorption holes can still maintain stable adsorption of the tape, ensuring the continuity and reliability of the slitting process. It should be noted that the number and layout of the first adsorption holes can be adjusted according to the width of the tape, and this embodiment does not limit this.

[0051] Specifically, Figure 1 As shown, the second adsorption member is an adsorption roller 5, and a plurality of second adsorption hole groups are formed on the adsorption roller 5. The band segments of the plurality of slit tapes on the adsorption roller 5 are used in a pair with the plurality of second adsorption hole groups. The adhesive tape is slit by the slitting mechanism 3 to form a plurality of slit tapes, and the band segments of the plurality of slit tapes on the adsorption disk 4 correspond to a group of second adsorption hole groups. The second adsorption hole groups can form a local negative pressure area to adsorb the band segments thereon, so that the slit segments of the adhesive tape can remain stable.

[0052] In this embodiment, a group of second adsorption holes includes a plurality of second adsorption holes, and the plurality of second adsorption holes can evenly distribute the adsorption force on the tape segment, ensuring that the tape segment can be stably adsorbed over the entire width or length, and if one or a few of the second adsorption holes are blocked or fail, the remaining second adsorption holes can still maintain stable adsorption of the tape, ensuring the continuity and reliability of the slitting process. It should be noted that the number and layout of the second adsorption holes can be adjusted according to the width of the slitting tape, and this embodiment does not limit this.

[0053] Specifically, the tape slitting device also includes a first driving member (not shown in the figure), which can drive the adsorption roller 5 to rotate around its own axis, so that the adsorption roller 5 drives the slitting tape to be transported downstream. In this embodiment, the first driving member is a rotating motor, and the driving end of the rotating motor is connected to the adsorption roller 5. The driving end of the rotating motor rotates to drive the adsorption roller 5 to rotate, thereby providing a driving force to the slitting tape to drive it to move downstream. In other embodiments, the first driving member can also be a rotating cylinder. It should be noted that any structure in the prior art that can drive the adsorption roller 5 to rotate can be used as the first driving member in this embodiment, and this embodiment is not limited to this.

[0054] Specifically, Figure 3 As shown, the slitting mechanism 3 includes a plurality of slitting components 31, which correspond to slitting a plurality of tapes pulled out from the feed tray 2. The slitting components 31 include at least two mounting plates 311 spaced apart along the width direction of the tape, and a blade 312 is sandwiched between two adjacent mounting plates 311. Each tape pulled out from the feed tray 2 corresponds to a slitting component 31, so that multiple tapes can be slid at the same time, greatly improving production efficiency. By setting the mounting plate 311, the blade 312 is sandwiched between the two mounting plates 311, which ensures the stability and accuracy of the blade 312 during the slitting process and reduces the possibility of the blade 312 shifting or shaking.

[0055] It is understandable that the number of mounting plates 311 and blades 312 is determined according to actual needs. Figure 3 As shown, in this embodiment, one tape needs to be cut into five strips, so the number of blades 312 is four, and the number of mounting plates 311 is five.

[0056] Specifically, the blade 312 is a ceramic blade or a tungsten steel blade. Both have high hardness, can maintain high precision and stability when cutting the tape, and reduce the error caused by the wear of the blade 312. It should be noted that the specific material of the blade 312 is determined according to actual needs, and this embodiment does not limit it.

[0057] In this embodiment, if Figure 3 As shown, the side of the mounting plate 311 facing the slitting section is provided with an arc surface 3111, and the tape section of the slitting section located on the mounting plate 311 is attached to the arc surface 3111. The first adsorbent and the second adsorbent work together to adsorb and fix the tape respectively to form a stable slitting section. The design of the arc surface 3111 ensures that the mounting plate 311 will not interfere with the slitting section, and can better fit the slitting section to provide support and guidance for it.

[0058] Furthermore, the mounting plate 311 has an adsorption chamber inside, and an adsorption port is provided on the arc surface 3111, which is connected to the adsorption chamber, so that the mounting plate 311 can adsorb the tape segment on which the slitting segment is located. Through this arrangement, the slitting segment is adsorbed and fixed by the mounting plate 311 during slitting, and is more stable and less likely to shake during the slitting process, making the slitting operation more accurate, and ensuring that the edge of the slitting tape is flat and will not be corrugated or jagged.

[0059] Specifically, Figure 1 As shown, the tape slitting device further includes a differential roller set 6, which is located at the downstream side of the second adsorbent. The differential roller set 6 includes a plurality of differential rollers 61, and the plurality of differential rollers 61 are located at different horizontal lines. Two adjacent slitting tapes are guided by different differential rollers 61. Each slitting tape can be guided and transported by the differential roller 61, and cross interference between adjacent slitting tapes can be avoided. Through this staggered traction method, adjacent slitting tapes can be separated from each other, and secondary adhesion of the slitting tapes after slitting can be avoided.

[0060] Specifically, Figure 1 As shown, the tape slitting device further includes a weight mechanism 7, which is located at the downstream side of the differential roller group 6. The weight mechanism 7 can move in the vertical direction to tension the slitting tape. By setting the weight mechanism 7, the slitting tape can be straightened to be supplied to the rear end for use.

[0061] In this embodiment, continue to refer to Figure 1 The weight mechanism 7 includes a base 71, a weight roller 72 and a second driving member (not shown in the figure). The weight roller 72 is slidably mounted on the base 71 in the vertical direction through a connecting frame 73, and the second driving member can drive the weight roller 72 to move in the vertical direction. In this embodiment, the second driving member is a linear motor, and the driving end of the linear motor is connected to the connecting frame 73 to drive the weight roller 72 to move in the vertical direction. In other embodiments, the second driving member can also be a cylinder. It should be noted that any structure in the prior art that can drive the weight roller 72 to move in the vertical direction can be used as the second driving member in this embodiment, and this embodiment is not limited to this.

[0062] Furthermore, a guide member is provided in the seat body 71, and the guide member extends in the vertical direction, and the guide member can provide guidance for the movement of the weight roller 72. By providing the guide member, the movement of the weight roller 72 in the vertical direction is guided, and the weight roller 72 is prevented from being deflected in other directions under the driving action of the second driving member.

[0063] In some embodiments, the guide member includes a slide rail and a slider that are slidably matched, the slide rail is vertically extended and arranged on the seat body 71, and the slider is arranged on the connecting frame 73. In this embodiment, the guide member is a guide rod 74, the guide rod 74 is vertically extended and arranged on the seat body 71, and the connecting frame 73 is penetrated by the guide rod 74.

[0064] Specifically, Figure 2 As shown, the suction roller 5 is provided with a plurality of first guide grooves 51 extending along the circumference thereof, and the plurality of first guide grooves 51 are arranged at intervals along the axial direction of the suction roller 5, and the plurality of slit tapes are located one by one in the plurality of first guide grooves 51. The first guide grooves 51 provide a clear path for the slit tapes, ensuring that the slit tapes can be conveyed on the suction roller 5 according to a predetermined track, and preventing adjacent slit tapes from deviating and sticking to each other during the conveying process.

[0065] In an optional embodiment, if Figure 1 As shown, the tape slitting device also includes a plurality of spacing rollers 8, all of which are located on the downstream side of the second adsorption member and distributed in the conveying path of the slitting tape to guide the slitting tape. The spacing roller 8 is provided with a plurality of second guide grooves extending along its circumference. The plurality of second guide grooves are arranged at intervals along the axial direction of the spacing roller 8. The distance between two adjacent second guide grooves is x1. The plurality of slitting tapes are located one by one in the plurality of second guide grooves. Among two adjacent spacing rollers 8, the x1 of the downstream spacing roller 8 is greater than the x1 of the upstream spacing roller 8.

[0066] The second guide groove provides a clear path for the slitting belt, ensuring that the slitting belt can be transported on the spacing roller 8 according to the predetermined track; between two adjacent spacing rollers 8, the x1 of the spacing roller 8 located downstream is greater than the x1 of the spacing roller 8 located upstream, that is, along the transportation direction of the slitting belt, the x2 on each spacing roller 8 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.

[0067] It should be noted that guide grooves may also be provided on other rollers on the tape slitting device, such as the weight roller 72 and the differential roller 61, and the spacing between the guide grooves on each roller gradually increases along the transport direction of the slitting tape, so that the slitting tape can be gradually dispersed during the transportation process. This can be flexibly designed according to actual conditions and is not limited in this embodiment.

[0068] Specifically, Figure 1 As shown, the tape slitting device further comprises a mounting frame 9, and all the above-mentioned structures are mounted on the mounting frame 9.

[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.
