[0001] This utility model relates to the field of lithium battery production technology, and in particular to a bonding device. This utility model also relates to a stacking equipment equipped with the aforementioned bonding device. Background Technology

[0002] In lithium-ion battery production, the stacking process involves a high-positioned feed platform. When changing battery material rolls, personnel, aided by climbing equipment, must manually pull the material roll to the feed platform. This process requires the roll to pass through multiple rollers along a narrow path, necessitating multiple people working together to complete the feed roll connection. This method results in low efficiency and poses a risk of operator injury during the process. Utility Model Content

[0003] In view of this, the present invention aims to provide a belt splicing device to facilitate the smooth operation of belt splicing and to improve splicing efficiency.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A tape receiving device includes a fixing frame with a tape receiving platform, a tape fixing unit disposed on the tape receiving platform, and a tape feeding part;

[0006] The connecting platform is used to support the first and second material strips to be connected;

[0007] The material belt fixing unit is used to fix the first material belt and the second material belt, and the material belt fixing unit can move upward along the height direction of the fixing frame, and lift the fixed first material belt and the second material belt from the initial position to the preset position;

[0008] The tape feeding unit can reciprocate along a direction orthogonal to the tape conveying direction. In the initial position, the tape in the tape feeding unit is pulled out and can be adhered to the upper surface of the docking position of the first tape and the second tape. In the preset position, the tape feeding unit moves and the tape wraps around to the underside of the first tape and the second tape, and can be adhered to the lower surface of the docking position.

[0009] Furthermore, the tape receiving platform is provided with a cutting groove extending orthogonally to the tape conveying direction; a tape cutting part is provided on one side of the tape feeding part, and the tape cutting part and the tape feeding part can move synchronously along the cutting groove. The tape cutting part is used to cut the first tape and the second tape stacked on the tape receiving platform, so that the tail end of the first tape and the head end of the second tape after cutting are respectively located on both sides of the cutting groove.

[0010] Furthermore, the material strip fixing unit is provided on both sides of the cutting groove; each material strip fixing unit includes a lifting member that is vertically and flexibly disposed on the receiving platform, and a pressing member disposed on the lifting member, the pressing member being able to press the first material strip or the second material strip onto the lifting member.

[0011] Furthermore, the clamping member and the lifting member are detachably connected.

[0012] Furthermore, the connecting platform is provided with a drive unit for driving each of the lifting components to rise and fall. The drive unit is one that is connected to each of the lifting components, or the drive unit is multiple that are provided in a one-to-one correspondence with each of the lifting components.

[0013] Furthermore, the receiving platform is provided with mounting slots on both sides, and each of the lifting components is vertically and flexibly disposed in the mounting slot on the corresponding side; in the initial position, each of the lifting components is located in the corresponding mounting slot, and the upper surface of each of the lifting components is coplanar or nearly coplanar with the upper surface of the receiving platform; in the preset position, each of the lifting components is lifted above the corresponding mounting slot.

[0014] Furthermore, at least one of the lifting members is provided with a stop bar for the tape to pass through; the tape receiving platform is provided with a tape cutting part, the tape cutting part and the stop bar are located on the same side of the tape receiving platform, and the tape cutting part is capable of cutting the tape near the stop bar.

[0015] Furthermore, it also includes a waste collection box with a top opening and a side opening; the waste collection box is slidably disposed relative to the tape receiving platform along the extension direction of the cutting groove, and the waste collection box is provided with a mounting bracket, which is disposed near the side opening; the tape cutting part and the tape feeding part are disposed on the mounting bracket.

[0016] Furthermore, a guide structure is provided between the waste collection box and the receiving platform, the guide structure being used to guide the sliding of the waste collection box relative to the receiving platform.

[0017] Compared with the prior art, this utility model has the following advantages:

[0018] (1) The tape splicing device of this utility model is provided with a tape splicing platform for carrying the first and second tapes to be spliced, a tape fixing unit that can be raised and lowered on the tape splicing platform, and a tape feeding part that can reciprocate along a direction orthogonal to the tape conveying direction. When the tape fixing unit is in its initial position, the tape in the tape feeding part is pulled out and can be adhered to the upper surface of the splicing position of the first and second tapes. When the tape fixing unit drives the fixed first and second tapes to be raised to a preset position, the tape feeding part moves so that the tape wraps around to the bottom of the first and second tapes and adheres to the lower surface of the splicing position, thereby realizing the tape splicing operation of the first and second tapes. This structure can realize the tape splicing operation on one side of the tape splicing platform without the need for multiple people to cooperate, and facilitates the smooth progress of the tape splicing operation and helps to improve the splicing efficiency.

[0019] (2) A cutting groove extending orthogonal to the conveying direction of the material belt is set on the tape splicing platform so that the material belt cutting part and the tape feeding part can move synchronously along the cutting groove. On the one hand, the material belt cutting part can be used to cut the first material belt and the second material belt stacked on the tape splicing platform so that the tail end of the first material belt and the head end of the second material belt are located on both sides of the cutting groove, which can improve the neatness of the splicing position of the first material belt and the second material belt and thus improve the splicing quality. On the other hand, the cutting groove can also play a certain guiding role in the movement of the tape feeding part and the material belt cutting part.

[0020] (3) Material strip fixing units are provided on both sides of the cutting groove, which can effectively fix the first and second material strips on both sides of the cutting groove, preventing relative displacement between the first and second material strips and affecting the splicing quality. Each material strip fixing unit includes a lifting component and a clamping component. The lifting component can be used to lift the first or second material strip, and the cooperation between the clamping component and the lifting component can ensure the fixing effect of the first and second material strips.

[0021] (4) The clamping component and the lifting component are detachably connected. After the belt splicing operation is completed, the clamping component can be disassembled to prevent the clamping component from affecting the conveying of the belt after splicing, which is conducive to the smooth conveying of the belt downstream after splicing.

[0022] (5) By setting a drive unit on the connecting platform to drive the lifting of each lifting component, the automation level of the lifting of each lifting component can be improved. Furthermore, a single drive unit can be set to jointly drive the lifting of the lifting components on both sides, which helps save on the cost of the drive unit and better achieves synchronous lifting of the lifting components on both sides. Alternatively, multiple drive units can be set up, each corresponding to one of the lifting components. This not only achieves synchronous lifting of the lifting components on both sides but also allows for individual lifting of the lifting components on both sides, improving ease of use.

[0023] (6) By setting mounting grooves on both sides of the tape receiving platform, a mounting base can be provided for the installation of the lifting components, improving the installation effect of the lifting components and ensuring the reliability of the lifting components installed on the tape receiving platform. At the same time, when the lifting components are in the initial position, their upper surface is coplanar or nearly coplanar with the upper surface of the tape receiving platform, which can prevent damage to the first or second tape due to unevenness of the upper surfaces. In the preset position, each lifting component is lifted above the mounting groove, so that the first and second tapes are lifted to a certain height. This makes it easier for the tape feeding part and the tape cutting part to pass under the first and second tapes, and facilitates the tape to wrap around under the first and second tapes, so as to achieve the bonding of the tape on the lower surface of the joint position of the first and second tapes.

[0024] (7) A tape-blocking bar is provided on the lifting component to support and block the tape extending from the upper surface of the first and second tapes to the lower surface of the first and second tapes, preventing the electrode sheet from being damaged during tape splicing. At the same time, a tape cutting part is provided on the tape splicing platform, and the tape cutting part and the tape-blocking bar are arranged on the same side of the tape splicing platform. In this way, the excess tape near the tape-blocking bar can be cut off by the tape cutting part, thereby further improving the tape splicing quality.

[0025] (8) The waste collection box with a top opening and a side opening can be used to place the waste of the first and second strips after cutting. The side opening facilitates the sliding of the waste collection box relative to the tape-connecting platform along the extension direction of the cutting groove. The strip cutting part and the tape feeding part are set on the mounting bracket inside the waste collection box. This not only enables the strip cutting part and the tape feeding part to move synchronously along the cutting groove, but also helps to improve the integration of the structure and the compactness of the overall structure of the tape-connecting device.

[0026] (9) The setting of the guide structure is conducive to guiding the waste collection box to slide relative to the connecting platform, thereby improving the reliability and smoothness of the waste collection box moving along the extension direction of the cutting groove.

[0027] This utility model also proposes a stacking device, which includes a tape-connecting device as described above.

[0028] The stacking device of this utility model and the tape-connecting device described above have the same beneficial effects as the prior art, and will not be repeated here. Attached Figure Description

In addition, if terms such as "first" or "second" appear, they are also used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0046] Furthermore, in the description of this utility model, unless otherwise explicitly defined, the terms "installation," "connection," "joining," and "connector" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model in light of the specific circumstances.

[0047] In this utility model, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0048] The present invention will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0049] The first aspect of this utility model provides a tape splicing device, which is applied in a lithium battery stacking system and is mainly used for splicing battery materials. The tape splicing device of this embodiment is innovative in its structure, which facilitates the smooth operation of material splicing and improves splicing efficiency.

[0050] In existing technologies, the lamination process, a crucial step in lithium-ion battery production, primarily involves cutting the coiled electrode sheets into fixed-size sheets and stacking them into battery cells. During lamination, due to the high positioning of existing material receiving platforms, personnel, aided by climbing equipment, must manually pull the material strip to the receiving platform when changing battery material coils. This process requires the strip to pass through multiple rollers, and the narrow path necessitates multiple people working together to complete the strip receiving operation. This method results in low efficiency and poses a risk of operator injury during the process.

[0051] In view of this, in order to overcome the shortcomings of the prior art, the connecting device in this embodiment combines... Figures 1 to 4 In terms of overall structure, it includes a fixing frame 1 with a tape receiving platform 101, a tape fixing unit 2 disposed on the tape receiving platform 101, and a tape feeding part 3.

[0052] The receiving platform 101 is used to support the first material strip 100 and the second material strip 200 to be connected. The material strip fixing unit 2 is used to fix the first material strip 100 and the second material strip 200, and the material strip fixing unit 2 can move upward along the height direction of the fixing frame 1, so that the fixed first material strip 100 and the second material strip 200 can be lifted from the initial position to the preset position.

[0053] The tape feeding unit 3 can reciprocate along a direction orthogonal to the tape conveying direction. In the initial position, the tape in the tape feeding unit 3 is pulled out and can be bonded to the upper surface of the docking position of the first tape 100 and the second tape 200. In the preset position, the tape feeding unit 3 extends below the first tape 100 and the second tape 200 and moves orthogonal to the tape conveying direction, so that the tape wraps around to the lower surface of the first tape 100 and the second tape 200 and can be bonded to the lower surface of the docking position.

[0054] Therefore, by coordinating the lifting and lowering movement of the belt fixing unit 2 with the movement of the belt feeding unit 3 along a direction orthogonal to the belt conveying direction, the belt splicing operation of the first belt 100 and the second belt 200 on the splicing platform 101 can be realized. Moreover, this structure allows for belt splicing operations to be performed on one side of the splicing platform 101 without the need for multiple people, facilitates smooth belt splicing operations, and helps improve splicing efficiency.

[0055] It is understood that the first strip 100 and the second strip 200 mentioned above are battery materials, which can be electrode sheets or separators, or uncoated foil, etc. The strip connection device in this embodiment is used to connect the first and second ends of the two strips in order to facilitate the smooth supply of subsequent battery materials and ensure the orderly progress of the battery production process.

[0056] Based on the above overall introduction, specifically, as an exemplary structural form, the strapping device in this embodiment still consists of... Figures 1 to 4 and combined Figure 5 and Figure 7 As shown, it mainly includes a tape-joining platform 101, a tape fixing unit 2, and a tape feeding unit 3. The tape-joining platform 101 is used to support the first tape 100 and the second tape 200 being joined. The tape-joining platform 101 is fixed to a fixing frame 1 and connected to a fixed foundation via the fixing frame 1. In specific implementations, it can be fixed to the platform between two battery material rolls, for example, by welding or screwing. Figure 5 and Figure 7 In this way, the fixing frame is welded and fixed to the platform between the first battery material roll 10 and the second battery material roll 20.

[0057] In addition, the tape fixing unit 2 is used to fix the first tape 100 and the second tape 200. The tape fixing unit 2 is vertically and vertically mounted on the tape receiving platform 101, so that the fixed first tape 100 and the second tape 200 can be raised from their initial positions to preset positions, thereby avoiding the tape feeding part 3 and ensuring the smooth movement of the tape feeding part 3. At the same time, the tape feeding part 3 can reciprocate along a direction orthogonal to the tape conveying direction. The tape in the tape feeding part 3 is pulled out and can be successively bonded to the upper surface and the lower surface of the docking position of the first tape 100 and the second tape 200.

[0058] Continue to refer to Figures 1 to 4 and combined Figure 5 and Figure 6 As shown, in some exemplary embodiments, in this embodiment, for example, a cutting groove 102 extending orthogonally to the conveying direction of the tape is provided on the tape receiving platform 101, and a tape cutting part 4 is provided on one side of the tape feeding part 3. The tape cutting part 4 and the tape feeding part 3 can move synchronously along the cutting groove 102. The tape cutting part 4 is used to cut the first tape 100 and the second tape 200 stacked on the tape receiving platform 101, so that the tail end of the first tape 100 and the head end of the second tape 200 after cutting are respectively located on both sides of the cutting groove 102.

[0059] At this time, a cutting groove 102 extending orthogonal to the conveying direction of the tape is provided on the tape-connecting platform 101, so that the tape cutting part 4 and the tape feeding part 3 can move synchronously along the cutting groove 102. On the one hand, the tape cutting part 4 can first cut the first tape 100 and the second tape 200 stacked on the tape-connecting platform 101, so that the tail end of the first tape 100 and the head end of the second tape 200 are located on both sides of the cutting groove 102, which can improve the neatness of the connection position of the first tape 100 and the second tape 200, which is conducive to improving the tape-connecting quality. On the other hand, the cutting groove 102 can also play a certain guiding role in the movement of the tape feeding part 3 and the tape cutting part 4 orthogonal to the conveying direction of the tape.

[0060] In some exemplary embodiments, such as this one, it is preferable to provide strip fixing units 2 on both sides of the cutting groove 102. This allows for better fixing of the first strip 100 and the second strip 200 on both sides of the cutting groove 102, preventing relative displacement between the first strip 100 and the second strip 200 that could affect the splicing quality.

[0061] As an exemplary structure, the material strip fixing unit 2 in this embodiment includes, for example, a lifting member 21 and a pressing member 22. The lifting member 21 is vertically and flexibly mounted on the receiving platform 101, and the pressing member 22 is mounted on the pressing member 22. The pressing member 22 can press the first material strip 100 or the second material strip 200 onto the lifting member 21. At this time, by using the lifting member 21 to lift, the first material strip 100 or the second material strip 200 can be lifted, and the cooperation between the pressing member 22 and the lifting member 21 can ensure the fixing effect of the first material strip 100 and the second material strip 200.

[0062] Still refer to Figures 1 to 4 As shown, in terms of specific structure, each lifting member 21 includes, for example, a long strip-shaped support plate 211 extending along the extension direction of the cutting groove 102, and a vertical rod 212 connected to the support plate 211. The support plate 211 supports the first material strip 100 or the second material strip 200, and the vertical rod 212 is inserted into a through hole on the receiving platform 101 for connection with the driving unit 5 described below. Thus, driven by the driving unit 5, the vertical rod 212 moves up and down in the through hole, thereby causing the lifting member 21 as a whole to rise and fall along the height direction of the receiving platform 101.

[0063] To improve the stability of the lifting member 21 during its lifting and lowering process, in this embodiment, for example, a guide rod 213 is provided on the support plate 211. The guide rod 213 consists of two rods located at both ends of the support plate 211, and the aforementioned vertical rod 212 is located between the two guide rods 213. This arrangement not only guides the lifting and lowering of the lifting member 21, but also improves the stability of the lifting and lowering of the lifting member 21.

[0064] Reference Figure 3 and Figure 4 and combined Figure 7 As shown, in some exemplary embodiments, such as this embodiment, the conveyor platform 101 is provided with a drive unit 5 for driving each lifting member 21 to rise and fall. The drive unit 5 is one that is connected to each lifting member 21, or there are multiple drive units 5 that are provided in a one-to-one correspondence with each lifting member 21.

[0065] At this point, the installation of the drive unit 5 can improve the automation level of the lifting and lowering of each lifting component 21. Furthermore, the drive unit 5 can be configured as a single unit, jointly driving the lifting and lowering of both sides of the lifting components 21. This helps to save the cost of the drive unit 5 and better achieve synchronous lifting and lowering of the lifting components 21 on both sides. Alternatively, multiple drive units 5 can be configured, each corresponding to one of the lifting components 21. This not only enables synchronous lifting and lowering of the lifting components 21 on both sides but also allows for individual lifting and lowering of the lifting components 21 on both sides, improving ease of use.

[0066] In a preferred embodiment, a drive unit 5 is fixedly connected to each lifting member 21 at the bottom of the receiving platform 101. The power output end of each drive unit 5 is connected to the corresponding vertical rod 212, meaning that each lifting member 21 is driven individually by its corresponding drive unit 5. It can be understood that the drive unit 5 can be a linear drive device such as a cylinder, hydraulic cylinder, or linear motor to provide linear driving force to the vertical rod 212, facilitating the linear movement of the lifting member 21.

[0067] In this embodiment, the clamping member 22 is also elongated, and preferably, the clamping member 22 is detachably connected to the lifting member 21. This arrangement allows the clamping member 22 to be disassembled after the belt splicing operation is completed, preventing it from affecting the conveying of the belt after splicing, thus facilitating the smooth downstream conveying of the belt after splicing.

[0068] In terms of specific structure, preferably, the clamping member 22 and the lifting member 21 are magnetically connected, which further facilitates the disassembly of the clamping member 22. In specific implementation, to achieve the magnetic connection between the clamping member 22 and the lifting member 21, for example, magnets are embedded in the clamping member 22, and iron blocks are embedded in the lifting member 21 at positions corresponding to the magnets. The magnets are, for example, a plurality of them arranged at intervals along the length of the clamping member 22, and the iron blocks are a plurality of them arranged one-to-one with the magnets. In this way, the magnetic connection between the clamping member 22 and the lifting member 21 is achieved through the cooperation of the magnets and the iron blocks.

[0069] In addition, in this embodiment, one end of the clamping member 22 is provided with an arc-shaped hooking part 221, and the lifting member 21 is provided with a hooking shaft 210. The hooking part 221 is sleeved on the hooking shaft 210 and can rotate around the hooking shaft 210. In this way, when the clamping member 22 clamps the first material strip 100 and the second material strip 200, the hooking part 221 and the hooking shaft 210 can play a certain positioning role for the clamping member 22.

[0070] It should be noted that, in addition to the magnetic attraction structure described above, the clamping member 22 and the lifting member 21 can also be connected by a detachable connection such as screwing or snap-fit. However, the magnetic attraction connection is more convenient for disassembling the clamping member 22 and can better ensure the fixing effect of the first material strip 100 and the second material strip 200.

[0071] Depend on Figure 3 and Figure 4 As shown, in some exemplary embodiments, such as this embodiment, mounting grooves 1011 are provided on both sides of the receiving platform 101, that is, mounting grooves 1011 are provided on both sides of the cutting groove 102. The aforementioned lifting members 21 are vertically and flexibly disposed in the mounting grooves 1011 on the corresponding sides. Furthermore, in the initial position, each lifting member 21 is located in the corresponding mounting groove 1011, and the upper surface of each lifting member 21 is coplanar or nearly coplanar with the upper surface of the receiving platform 101. In the preset position, each lifting member 21 is lifted above the corresponding mounting groove 1011.

[0072] In specific implementation, the upper surface of the lifting member 21 is also the upper surface of the support plate 211. Furthermore, the aforementioned requirement that the upper surface of the lifting member 21 be coplanar or nearly coplanar with the upper surface of the receiving platform 101 means that the upper surface of the support plate 211 should be as coplanar as possible with the upper surface of the receiving platform 101. Nearly coplanar specifically means that due to machining accuracy or manufacturing errors, the upper surface of the lifting member 21 may be higher or lower than the upper surface of the receiving platform 101, resulting in a certain error compared to strict coplanarity. In this embodiment, the distance between the upper surface of the lifting member 21 and the upper surface of the receiving platform 101 should not exceed 0.1 mm.

[0073] At this time, by setting mounting grooves 1011 on both sides of the receiving platform 101, an installation foundation can be provided for the installation of the lifting component 21, improving the installation effect of the lifting component 21 and ensuring the reliability of the lifting component 21 on the receiving platform 101. At the same time, when the lifting component 21 is in the initial position, its upper surface is coplanar or nearly coplanar with the upper surface of the receiving platform 101, which can prevent damage to the first material belt 100 or the second material belt 200 due to unevenness of the upper surfaces of the two. In the preset position, each lifting component 21 is lifted above the mounting groove 1011, so that the first material belt 100 and the second material belt 200 are lifted to a certain height. This facilitates the passage of the tape feeding part 3 and the tape cutting part 4 under the first material belt 100 and the second material belt 200, and facilitates the tape to wrap around under the first material belt 100 and the second material belt 200, realizing the bonding of the tape on the lower surface of the joint position of the first material belt 100 and the second material belt 200.

[0074] Reference Figure 3 and Figure 4 and combined Figure 7 and Figure 8 As shown, in some exemplary embodiments, in this embodiment, for example, at least one of the lifting members 21 is provided with a tape stop bar 214 for the tape to pass through, and on this basis, the tape receiving platform 101 is also provided with a tape cutting part 11, the tape cutting part 11 and the tape stop bar 214 are located on the same side of the tape receiving platform 101, and the tape cutting part 11 can cut the tape near the tape stop bar 214.

[0075] In this embodiment, the adhesive-blocking rod 214 supports and blocks the tape extending from the upper surface of the first tape 100 and the second tape 200 to their lower surface, preventing damage to the electrode sheets during splicing. Simultaneously, a tape cutting part 11 is provided on the splicing platform 101, and the tape cutting part 11 and the adhesive-blocking rod 214 are arranged on the same side of the splicing platform 101. This allows the tape cutting part 11 to cut off excess tape near the adhesive-blocking rod 214, further improving the splicing quality.

[0076] In practical implementation, baffle rods 214 are provided on both lifting members 21, which can better and more stably support the tape and make the force on both lifting members 21 more balanced. It can be understood that, in addition to providing baffle rods 214 on both lifting members 21, it is also possible to provide baffle rods 214 on only one of the lifting members 21.

[0077] Furthermore, the tape cutting section 11 in this embodiment includes, for example, a tape cutter with serrations. This tape cutter is fixed to the end of the tape receiving platform 101, and the top of the serrations is higher than the upper surface of the tape receiving platform 101. This allows the tape near the tape stop bar 214 to be cut by the tape cutter when the lifting member 21 returns to its initial position. The tape cutting position Q is, for example... Figure 8 As shown in the image.

[0078] Reference Figure 3 and Figure 4 As shown, in some exemplary embodiments, this embodiment may further include, for example, a waste collection box 6 having a top opening 601 and a side opening 602. The waste collection box 6 is slidable relative to the tape receiving platform 101 along the extending direction of the cutting groove 102, and a mounting bracket 61 is provided inside the waste collection box 6, located near the side opening 602. The aforementioned tape cutting section 4 and tape feeding section 3 are specifically mounted on the mounting bracket 61.

[0079] By using the waste collection box 6 with a top opening 601 and a side opening 602, the waste from the first strip 100 and the second strip 200 after cutting can be placed using the top opening 601. The side opening 602 facilitates the sliding of the waste collection box 6 relative to the tape-connecting platform 101 along the extension direction of the cutting groove 102. The strip cutting part 4 and the tape feeding part 3 are mounted on the mounting bracket 61 inside the waste collection box 6. On the one hand, this allows the strip cutting part 4 and the tape feeding part 3 to move synchronously along the cutting groove 102. On the other hand, it also helps to improve the integration of the structure and increase the overall compactness of the tape-connecting device.

[0080] In specific implementation, the tape feeding section 3 includes a roll of tape fixed on the mounting bracket 61, and the tape feeding section 3 is closer to the side opening 602 than the tape cutting section 4, which facilitates the operation of cutting and bonding the first tape 100 and the second tape 200. Furthermore, the tape cutting section 4 preferably uses a cutter arranged at an angle on the mounting bracket 61; the angled cutter helps improve the cutting quality of the first tape 100 and the second tape 200. In addition, in this embodiment, a protective sleeve is provided on the top of the cutter to enhance safety during use.

[0081] To facilitate the movement of the waste collection box 6, in this embodiment, preferably, a handle 62 is provided on the side of the waste collection box 6 away from the side opening 602. By operating the handle 62, the waste collection box can be pulled out and pushed back, and the operation is convenient.

[0082] In addition, in some exemplary embodiments, such as this embodiment, a guide structure is provided between the two sides of the waste collection box 6 along the sliding direction and the receiving platform 101. The guide structure is used to guide the sliding of the waste collection box 6 relative to the receiving platform 101. By using the provided guide structure, the reliability and smoothness of the movement of the waste collection box 6 along the extension direction of the cutting groove 102 can be improved.

[0083] In practical implementation, the guide structure can, for example, adopt a combination of slide rails and chutes, where the slide rails are installed on the waste collection box 6, and the chutes are installed on the receiving platform 101. Of course, it is understandable that the slide rails can also be installed on the receiving platform 101, in which case the chutes are installed on the waste collection box 6, which is also acceptable.

[0084] In this embodiment, the tape-connecting device, during actual use, firstly, manually places the tail end of the first tape 100 and the head end of the second tape 200 onto the tape-connecting platform 101, wherein the first tape 100 and the second tape 200 have overlapping portions. Then, the clamping members 22 on both sides press the first tape 100 and the second tape 200 onto the corresponding lifting members 21 respectively, thus fixing the first tape 100 and the second tape 200. This state is as follows: Figure 5 As shown in the diagram. Then, as... Figure 6 As shown, the waste collection box 6 is pulled out, so that the material strip cutting part 4 cuts the first material strip 100 and the second material strip 200. The tail end of the first material strip 100 and the head end of the second material strip 200 after cutting are located on both sides of the cutting groove 102. At this time, the waste material cut above the first material strip 100 and the second material strip 200 is taken out and placed in the waste collection box 6.

[0085] Next, the tape in the tape feeding section 3 is pulled out, so that the end of the tape is adhered to the first end of the tape receiving platform 101. Then, the waste collection box 6 is pushed back to its original position. At this time, while the end of the tape is pressed, the tape continues to be pulled out. Then, by manually pressing down on the tape, the tape is adhered to the upper surface of the joint position of the first tape 100 and the second tape 200. Next, driven by the drive unit 5, the lifting rods on both sides are raised simultaneously, raising the first tape 100 and the second tape 200 fixed on the lifting member 21 to the preset position. The state of being raised to the preset position is as follows. Figure 7 As shown in the figure, at this time, the upper surfaces of the first material strip 100 and the second material strip 200 have been glued with adhesive tape, and at this time, the waste material located on the lower surfaces of the first material strip 100 and the second material strip 200 after cutting is manually picked up and placed into the waste material collection box 6.

[0086] Then, pull out the waste collection box 6 again. At this time, the tape wraps around the glue-blocking bar 214 and is located below the lower surfaces of the first material strip 100 and the second material strip 200. Next, lower the lifting members 21 on both sides from the preset position to the initial position, and manually press the joint position to make the tape adhere to the lower surface of the joint position of the first material strip 100 and the second material strip 200. At the same time, when the lifting member 21 is lowered to the initial position, the tape cutting part 11 is used to cut the tape near the glue-blocking bar 214, that is, at the tape cutting position Q. The cut tape 1000 is as follows. Figure 8 As shown, the bonding and connection of the first material belt 100 and the second material belt 200 is now complete. Finally, the clamping member 22 is removed from the lifting member 21, and the second material belt 200 can be conveyed downstream.

[0087] The tape splicing device of this embodiment can perform tape splicing operations on one side of the tape splicing platform 101 without the need for multiple people to cooperate, which facilitates the smooth progress of tape splicing operations and helps to improve splicing efficiency.

[0088] A second aspect of this utility model provides a stacking device, which includes the aforementioned tape-connecting device.

[0089] In specific implementation, refer to Figure 5 and Figure 7 As shown, for example, the splicing device is arranged on a platform between two battery material rolls, that is, the splicing device is fixed on a platform between the first battery material roll 10 and the second battery material roll 20. In this case, during the splicing operation, the material roll does not need to pass through the roller or other narrow space, which facilitates the splicing operation and the efficient splicing, and also avoids the risk of employees being squeezed during the splicing operation.

[0090] The stacking equipment of this embodiment, by adopting the above-mentioned tape-joining device, can perform tape-joining operations on one side of the tape-joining platform 101 without the need for multiple people to cooperate, and can ensure the smooth progress of tape-joining operations, and is conducive to improving tape-joining efficiency, thus having a very good usage effect.

The technical features or structures in the foregoing different embodiments can be arbitrarily combined to form other specific technical solutions as needed. For those skilled in the art, this utility model can have various modifications and variations.
