Description

Technical Field

[0001] This utility model relates to the field of tape cutting technology, and in particular to a cutting mechanism and tape cutting equipment. Background Technology

[0002] In lithium battery manufacturing, tape is used repeatedly for bonding and fixing, such as after cell stacking and after electrode welding. The tape is typically unwound by rollers, cut to the required length by a cutting mechanism, and then transported to the specific location on the battery for application by a bonding machine. Existing cutting mechanisms mostly use cylinders or electric cylinders to directly drive the cutter head in a linear motion. This driving method is difficult to meet the needs of production scenarios with compact structural space requiring cutting on both sides. Specifically, cutting on both sides means two cutters, each driven by a cylinder or electric cylinder, which is costly and occupies assembly space. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a cutting mechanism with a compact structure that can cut rubber on both sides.

[0022] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0023] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0025] Please refer to Figures 1 to 3 A cutting mechanism 1 includes a mounting plate 11, on which two blade holders 15 are slidably mounted. Each blade holder 15 is equipped with a cutting tool. The mechanism also includes a drive block 13 adjustablely mounted on the mounting plate 11. The drive block 13 acts on the two blade holders 15, allowing them to move closer or further apart along a first direction X. The drive block 13 moves along a second direction Y, where the first direction X is perpendicular to the second direction Y. Each blade holder 15 is equipped with a cutting head 16. In this embodiment, one drive block 13 drives both blade holders 15, i.e., both cutting heads 16, allowing them to move closer or further apart, thereby enabling the cutting heads 16 to cut the tape 211. Figure 1 As shown, it can be understood that the tape 211 corresponding to the blade head 16 of the cutting mechanism 1 is located outside the blade holder 15, that is, the direction of movement of the blade head 16. Since the direction of movement of the drive block 13 is perpendicular to the direction of movement of the blade holder 15, the compactness of the assembly structure of the two blade holders 15 can be improved in the direction of movement of the blade holder 15, that is, in the first direction X, thereby reducing the assembly space of the cutting mechanism 1. This is beneficial for assembly and use in adhesive cutting equipment or adhesive application equipment, while reducing the number of drive mechanisms and saving production costs.

[0026] Specifically, such as Figure 1 and Figure 2 As shown, the drive block 13 and the tool holder 15 are connected by connecting plates 14. There are two connecting plates 14, each corresponding to one of the two tool holders 15. One end of the connecting plate 14 is pivotally connected to the tool holder 15, and the other end is pivotally connected to the drive block 13. The pivot axis between the connecting plate 14 and the tool holder 15 is defined as the first axis a, and the pivot axis between the connecting plate 14 and the drive block 13 is defined as the second axis b. The first axis a and the second axis b are parallel, and the first axis a is perpendicular to the plane defined by the first direction X and the second direction Y. In this embodiment, the plane defined by the first direction X and the second direction Y is parallel to the mounting plate 11. Specifically, the tool holder 15 is slidably connected to the mounting plate 11 through a slide rail slider assembly. The mounting plate 11 is provided with a first drive member 12, including but not limited to a cylinder or an electric cylinder. The drive block 13 is assembled to the first drive member 12 and is driven by it to move along the second direction Y. In use, when tape 211 needs to be cut, the connecting plate 14 transmits the force of the drive block 13 to the blade holder 15, realizing the conversion of the perpendicular movement direction of the blade holder 15 and the drive block 13, such as... Figure 2 As shown, the two connecting plates 14 are driven by the same drive block 13, which is simple and compact in structure, and at the same time can provide the knife holder 15 with a larger stroke, which is beneficial to the smooth cutting of the tape 211.

[0027] like Figure 2As shown, in some embodiments, the axial direction of the first axis a and the second axis b is defined as the third direction Z, and the first direction X, the second direction Y, and the third direction Z are perpendicular to each other. In the third direction Z, the connecting plate 14 is positioned between the mounting plate 11 and the tool holder 15. To provide sufficient space for the connecting plate 14 to move, a pad 18 is provided on the mounting plate 11, and a slide rail is mounted on the pad 18.

[0028] In this embodiment, the cutting mechanism 1 further includes a base plate 17, and the mounting plate 11 is detachably mounted on the base plate 17. This facilitates the assembly of the cutting mechanism 1 with other equipment and also facilitates the maintenance of the cutting mechanism 1.

[0029] Furthermore, such as Figure 3 As shown, a linear guide rail extending along the second direction Y is disposed on the base plate 17, and a sliding block is disposed on the mounting plate 11 to slidably engage with the linear guide rail. One end of the linear guide rail is provided with a first engaging portion 172, and the mounting plate 11 is provided with a second engaging portion 112 adapted to the first engaging portion 172. The combination of the sliding block and the linear guide rail can be a slide rail-slider assembly. The engagement of the first engaging portion 172 and the second engaging portion 112 fixes the relative position of the mounting plate 11 and the base plate 17 in the second direction Y, while also facilitating the removal of the mounting plate 11 from the base plate 17. Optionally, the combination of the first engaging portion 172 and the second engaging portion 112 can be a ball joint.

[0030] The base plate 17 is provided with a locking groove 173 extending along the second direction Y. The mounting plate 11 is threaded with a locking bolt 113 corresponding to the locking groove 173, and the locking bolt 113 can extend into the locking groove 173. The locking bolt 113 here cooperates with the first snap-fit ​​part 172 and the second snap-fit ​​part 112 to more securely assemble the mounting plate 11 in the second direction Y.

[0031] like Figure 4 and Figure 5 As shown, this embodiment also provides a tape cutting device, including a longitudinal plate 2 and the aforementioned cutting mechanism 1. The longitudinal plate 2 is provided with two unwinding rollers 21 corresponding to the two blade holders 15. The cutting mechanism 1 is mounted on the longitudinal plate 2. The two unwinding rollers 21 enable the tape cutting device to output two tapes 211 simultaneously. The cutting mechanism 1 achieves the cutting of the two tapes 211, resulting in high efficiency.

[0032] Furthermore, the longitudinal plate 2 is equipped with two pressure-pressing parts corresponding to the two blade holders 15. The pressure-pressing part includes a pressure-pressing assembly 22 and a tape-pulling assembly 23. The tape 211 extends from the self-unwinding roller 21 through the pressure-pressing assembly 22 to the tape-pulling assembly 23, and the blade 16 is located between the pressure-pressing assembly 22 and the tape-pulling assembly 23. In use, the pressure-pressing assembly 22 fixes the tape 211, and the tape-pulling assembly 23 clamps the free end of the tape 211 to cooperate with the pressure-pressing assembly 22 to tighten the tape 211 in the third direction Z to facilitate cutting by the blade 16.

[0033] like Figure 5 As shown, the adhesive application assembly 22 includes two first clamping plates 222 disposed opposite to each other on the longitudinal plate 2. The first clamping plates 222 are adjustablely connected to the longitudinal plate 2, and the adhesive tape 211 is located between the two first clamping plates 222. The two first clamping plates 222 can move closer to each other or further away from each other. Specifically, a first adapter plate 221 is provided on the longitudinal plate 2, and a finger cylinder is mounted on the first adapter plate 221. The two first clamping plates 222 are mounted on the finger cylinder and driven by it. That is, the first clamping plates 222 are adjustablely connected to the longitudinal plate 2 through the finger cylinder and the first adapter plate 221. The adhesive tape 211 is located between the two first clamping plates 222. In use, the two first clamping plates 222 move closer to each other to fix the adhesive tape 211.

[0034] like Figure 5 As shown, the adhesive-pulling assembly 23 includes an adhesive-pulling seat 231 movably disposed on the longitudinal plate 2. Two opposing second clamping plates 232 are adjustablely mounted on the adhesive-pulling seat 231. The two second clamping plates 232 can move closer to or further away from each other, allowing the adhesive-pulling seat 231 to move closer to or further away from the adhesive-pressing assembly 22. Specifically, the adhesive-pulling seat 231 is slidably connected to the longitudinal plate 2 via a slide rail slider assembly. Optionally, a second driving member 233 is mounted on the longitudinal plate 2 to drive the adhesive-pulling seat 231 to move closer to or further away from the adhesive-pressing assembly 22 along a third direction Z. The second driving member 233 includes, but is not limited to, a cylinder or an electric cylinder. In this embodiment, a finger cylinder is provided on the adhesive-pulling seat 231, and the two second clamping plates 232 are mounted on and driven by the finger cylinder to move closer to or further away from each other. In use, the two second clamping plates 232 cooperate to clamp the free end of the tape 211. The second driving component 233 drives the tape pulling seat 231 to move away from the pressing component 22 by a certain distance along the third direction Z. The pressing component 22 then presses and fixes the tape 211. At this time, the tape 211 is in a stretched and taut state. Finally, the tape 211 is cut by the cutter head 16.

[0035] like Figure 4As shown, a guide roller 24 is provided between the unwinding roller 21 and the pressure assembly 22. The tape 211 passes sequentially through the guide roller 24, the pressure assembly 22, and the stretching assembly 23. At least one guide roller 24 is adjustablely mounted on the longitudinal plate 2. Specifically, the axial direction of the guide roller 24 is parallel to the second direction Y. In this embodiment, a fixed seat is provided at the end of the guide roller 24 adjustablely mounted on the longitudinal plate 2 facing the longitudinal plate 2. The fixed seat is slidably mounted on the longitudinal plate 2 via a slide rail slider assembly. In use, the fixed seat is moved relative to the longitudinal plate 2 by a cylinder mounted on the longitudinal plate 2. Since the tape 211 is wound on the guide roller 24, after the tape 211 is fixed by the pressing assembly 22, the position of at least one guide roller 24 is adjusted to drive the unwinding roller 21 to rotate and unwind the tape 211. Then the guide roller 24 is reset, and the tape is pulled by the tape pulling assembly 23 to stretch the unwound tape 211 taut. In this way, the unwinding roller 21 does not need to be equipped with a drive device, saving the manufacturing cost of the equipment.

[0036] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
