[0032] During the production process of lithium batteries, electrodes or diaphragms are in the form of rolls and are installed in roll-to-roll assemblies for unwinding and feeding.

[0033] In the related art, the tape splicing device includes a first material roll assembly, a second material roll assembly, a loading assembly and a tape splicing mechanism. The loading assembly is used to receive the material tape released from the first material roll to form a working material tape. The tape splicing mechanism includes a tape cutting piece and a gluing piece. When the material roll of the first material roll assembly is almost used up, the tape cutting piece cuts the working material tape from the first material roll. After the material roll of the second material roll assembly is pulled, it is glued to the working material tape using the gluing piece to ensure continuous material supply of the device.

[0034] However, after the second material roll assembly is installed with the material roll, the tape splicing mechanism needs to pull the material roll of the second material roll assembly before it can bond the working material tape. The tape splicing steps are relatively cumbersome, resulting in a long tape splicing time, which is not conducive to improving production efficiency.

[0035] In order to solve the above problems, the present invention proposes a tape splicing device 10 , which aims to simplify the tape splicing steps of the tape splicing device 10 , shorten the tape splicing time, and improve production efficiency.

[0036] Reference Figures 1 to 6 In one embodiment of the present invention, the tape splicing device 10 includes a frame 1, a first material roll assembly 2, a second material roll assembly 3, a material carrier assembly 841, and a tape splicing assembly 5. The first material roll assembly 2 is mounted on the frame 1 for mounting a first material roll 91. The second material roll assembly 3 is mounted on the frame 1 and is spaced apart from the first material roll assembly 2 for mounting a second material roll 92. The end 921 of the second material roll 92 is provided with an adhesive surface 9535. The material carrier assembly 841 is mounted on the frame 1 and is spaced apart from the first material roll assembly 2 and the second material roll assembly 3 for receiving a portion of the material tape released from the first material roll 91 to form a working material tape 93.

[0037] The tape connecting assembly 5 includes a first driving member 51, a tape pressing member 53 and a tape cutting member 55. The tape pressing member 53 is located on the side of the working material tape 93 away from the second winding assembly 3, and is connected to the frame 1 for sliding in the direction of approaching or moving away from the working material tape 93 to press one side of the working material tape 93 against the adhesive surface 9535. The first driving member 51 is connected to the tape pressing member 53 to drive the tape pressing member 53 to slide. The tape cutting member 55 is connected to the tape pressing member 53 for cutting the part of the working material tape 93 connected to the first material roll 91.

[0038] The first and second winding assemblies 2 and 3 can each be provided with a first and second reels, which are respectively disposed through the first and second material rolls 91 and 92, so that the first and second material rolls 91 and 92 can rotate and unwind. The first and second reels can each be driven by a drive motor 511 as rotation drive ends 31, driving the first and second material rolls 91 and 92 to actively rotate.

[0039] The material carrier assembly 841 can be a guide roller assembly, which receives and guides the material strip unwound from the first or second material roll 91 , 92 . This portion of the material strip serves as the working material strip 93 for subsequent processing. The splicing device 10 also includes a traction assembly 84 and a tension adjustment assembly 81 . The traction rollers of the traction assembly 84 traction the working material strip 93 , thereby driving the first or second material roll 91 , 92 to be unwound and fed. The tension adjustment assembly 81 then adjusts the tension of the material strip to meet the requirements of the production process.

[0040] In the technical solution of the present invention, when the material roll of the first material roll assembly 2 is almost used up, the pressing member 53, under the drive of the first driving member 51, presses one side of the working material tape 93 against the bonding surface 9535 of the second material roll 92, so that one side of the working material tape 93 is bonded to the second material roll 92, and the part of the working material tape 93 connected to the first material roll 91 is cut by the tape cutting member 55, so that the working material tape 93 and the first material roll 91 are separated, so that the loading assembly 841 can take over the material tape unwound from the second material roll 92, thereby realizing continuous feeding of the device.

[0041] Therefore, after the second material roll 92 of the present invention is installed on the second material roll assembly 3, the tape splicing assembly 5 directly presses the working material tape 93 against the bonding surface 9535 of the second material roll 92 through the tape pressing member 53, so that the second material roll 92 does not need to be pulled for bonding. The splicing steps are relatively simple, the splicing time is shortened, and it is beneficial to improve production efficiency.

[0042] Optionally, the splicing device 10 also includes a manual splicing platform 87, which is located on the side of the first material roll 91 and the second material roll 92 away from the loading assembly 841. When the splicing assembly 5 is in an abnormal state, the operator can also manually splice the first material roll 91 or the second material roll 92, thereby achieving splicing of the first material roll 91 or the second material roll 92, which is beneficial to further ensure the continuous feeding of the device.

[0043] Optionally, the belt connecting device 10 also includes an iron removal component 82, an anti-static component 83 and an appearance detection component 85, wherein the iron removal component 82 and the anti-static component 83 can purify the material belt, place the material residue adsorbed on the material belt, and observe it through the appearance detection component 85 to ensure the production quality of the material belt.

[0044] Reference Figure 3 and Figure 4 In one embodiment of the present utility model, the belt connecting device 10 also includes a rack assembly 11, the rack assembly 11 is connected to the frame 1, the first driving member 51 includes a driving motor 511 and a driving gear 513, the driving motor 511 is connected to the belt pressing member 53, the driving gear 513 is connected to the output shaft of the driving motor 511, and is meshed with the rack assembly 11 to drive the belt pressing member 53 to slide.

[0045] In this embodiment, the belt pressing member 53 uses a gear rack transmission structure to achieve automatic sliding on the frame 1 and automatic pressing against the working material belt 93, which is conducive to achieving precise control of the sliding stroke of the belt pressing member 53, ensuring that the belt pressing member 53 fully presses the working material belt 93 against the bonding surface 9535, and ensuring normal splicing of the belt splicing assembly 5.

[0046] Reference Figure 3 and Figure 4In one embodiment of the present invention, the belt connecting assembly 5 also includes a first guide rail 57, which is installed on the frame 1. The first guide rail 57 extends along a sliding direction parallel to the belt pressing member 53, and the belt pressing member 53 is slidably connected to the first guide rail 57.

[0047] In this embodiment, the sliding of the belt pressing member 53 is guided by the first guide rail 57, which can ensure the sliding stability of the belt pressing member 53, prevent the belt pressing member 53 from shifting during the sliding process, ensure that the working material belt 93 is pressed against the adhesive surface 9535 of the second material roll 92, and ensure the normal splicing of the belt splicing assembly 5.

[0048] Reference Figure 3 and Figure 4 In one embodiment of the present invention, the tape cutting member 55 includes a cutting cylinder 551 and a cutter 553. The cutting cylinder 551 is connected to the tape pressing member 53, and the cutter 553 is connected to the telescopic part of the cutting cylinder 551 for cutting the working material tape 93.

[0049] In this embodiment, the cutter 553 is driven by the telescopic portion of the cutting cylinder 551 to cut the working material strip 93 and separate the working material strip 93 from the first material roll 91. Therefore, the cylinder drive method ensures cutting force while also achieving rapid cutting of the working material strip 93, which is conducive to improving production efficiency.

[0050] Reference Figure 3 and Figure 4 In one embodiment of the present invention, the tape cutting member 55 also includes a second guide rail 555, which is installed on the tape pressing member 53 and extends along the telescopic direction of the telescopic part of the cutting cylinder 551, and the cutter 553 is slidably connected to the second guide rail 555.

[0051] In this embodiment, the second guide rail 555 is used to guide the sliding of the cutter 553, which can ensure the sliding stability of the cutter 553, prevent the cutter 553 from shifting during the sliding process, ensure that the cutter 553 accurately cuts the working material strip 93, and enables the working material strip 93 to be separated from the first material roll 91 in a timely manner, thereby ensuring the normal production of the equipment.

[0052] Reference Figure 3 and Figure 4In one embodiment of the present invention, the strip cutting member 55 further includes a heating member 557, which is connected to the telescopic portion of the cutting cylinder 551. The heating member 557 is provided with a mounting groove on the surface facing the working material strip 93, and the groove wall of the mounting groove is provided with a power-passing hole. Both ends of the cutter 553 are connected to the heating member 557 and partially pass through the power-passing hole for electrical heating.

[0053] In this embodiment, the cutter 553 is electrically heated by the heating element 557 so that the cutter 553 has a first temperature, thereby achieving thermal cutting of the working material strip 93, which is conducive to achieving rapid separation of the working material strip 93 and improving production efficiency.

[0054] Reference Figures 2 to 4 In one embodiment of the present invention, the bonding surface 9535 is generally arc-shaped, and the belt pressing member 53 includes a first bracket 531 and a pressure roller 533. The first bracket 531 is slidably connected to the frame 1, and the pressure roller 533 is connected to the side of the first bracket 531 facing the bonding surface 9535. The pressure roller 533 is used to press against the side of the working material belt 93 away from the bonding surface 9535.

[0055] In this embodiment, the outer surface cross-section of the second material roll 92 is circular, and the bonding surface 9535 is generally arc-shaped. The working material tape 93 is pressed against the bonding surface 9535 by the pressure roller 533, so that the working material tape 93 and the bonding surface 9535 are in arc-shaped contact, which is beneficial to increase the contact area between the working material tape 93 and the bonding surface 9535, and then enhance the bonding force to ensure the normal splicing of the splicing assembly 5.

[0056] Reference Figures 2 to 4 In one embodiment of the present invention, there are two connecting tape assemblies 5, and the two connecting tape assemblies 5 are arranged on opposite sides of the working material tape 93. The pressing piece 53 of one connecting tape assembly 5 is used to press the working material tape 93 against the adhesive surface 9535 provided on the first material roll 91, and the pressing piece 53 of the other connecting tape assembly 5 is used to press the working material tape 93 against the adhesive surface 9535 provided on the second material roll 92.

[0057] In this embodiment, the first material roll 91 and the second material roll 92 can alternately release the working material tape 93. Therefore, by providing two sets of splicing components 5, when the material roll of one of the first material tape and the second material roll 92 is almost used up, the other one can be used as a spare material roll. The spare material roll can be spliced ​​by a corresponding set of splicing components 5 to achieve alternating material preparation of the first material roll 91 and the second material roll 92, further ensuring the continuous material supply of the device and improving production efficiency.

[0058] Reference Figures 2 to 4In one embodiment of the present invention, the second material winding assembly 3 is provided with a rotating drive end 31, and the second material roll 92 is connected to the rotating drive end 31 for rotation. The tape splicing device 10 also includes an identification assembly 6, and the identification assembly 6 is installed on the frame 1 and is spaced apart from the first material winding assembly 2. The identification assembly 6 is used to identify the bonding surface 9535. The first material winding assembly 2 controls the rotation stroke of the first material roll 91 according to the identification information of the identification assembly 6, so as to set the bonding surface 9535 toward one side of the tape pressing member 53.

[0059] In this embodiment, after the second material roll 92 is installed in the second winding assembly 3, the position of the adhesive surface 9535 of the second material roll 92 is unknown, making it impossible for the splicing assembly 5 to properly splice the tape. Therefore, the recognition assembly 6 identifies the position of the adhesive surface 9535 and controls the rotation of the second material roll 92, so that the adhesive surface 9535 faces the pressure piece of the splicing assembly 5, ensuring proper splicing of the splicing assembly 5. Therefore, this solution avoids manual measurement and adjustment of the second material roll 92 and instead achieves proper alignment of the second material roll 92 through automatic rotation and recognition of the second material roll 92, further improving production efficiency.

[0060] Reference Figure 2 In one embodiment of the present invention, the identification component 6 includes a second bracket 61 and a color mark sensor 63, the second bracket 61 is connected to the frame 1, and the color mark sensor 63 is connected to the side of the second bracket 61 facing the first roll component 2 to generate identification information based on the color difference between the adhesive surface 9535 and the first material roll 91.

[0061] In this embodiment, since there is a color difference between the adhesive surface 9535 and the outer surface of the second material roll 92, the color difference can be identified by the color mark sensor 63, so as to quickly determine the position of the adhesive surface 9535 in the second material roll 92, which is conducive to further improving production efficiency.

[0062] Reference Figure 2 、 Figure 5 and Figure 6In one embodiment of the present invention, the tape splicing device 10 also includes an adhesive member 95 and a separator 96, the adhesive member 95 includes a main body 951, a first adhesive layer 9513, and a second adhesive layer 9533, the first adhesive layer 9513 and the second adhesive layer 9533 are arranged at intervals on the same side of the main body 951, the first adhesive layer 9513 is bonded to the end 921 of the second material roll 92, and the bonding surface 9535 is formed on the side of the second adhesive layer 9533 facing away from the main body 951, and the separator 96 is arranged on the side of the main body 951 facing away from the first adhesive layer 9513, and is bonded to the outer surface of the roll body 923 of the second material roll 92.

[0063] In this embodiment, the adhesive member 95 is lifted up against the roll body 923 of the second material roll 92 by the separator 96, and the end 921 of the second material roll 92 is bonded to the first adhesive layer 9513. After the working material tape 93 is bonded to the adhesive surface 9535 of the second adhesive layer 9533, the second material roll 92 is unwound and fed. The adhesive member 95 moves synchronously with the unwinding of the second material roll 92, and the separator 96 temporarily remains on the roll body 923 of the second material roll 92. Therefore, this solution achieves the initial separation of the end 921 of the second material roll 92 and the roll body 923 by lifting the adhesive member 95 and initially bonding the end 921 of the second material roll 92 to the first adhesive layer 9513. Therefore, after the adhesive surface 9535 is bonded to the working material tape 93, the second material roll 92 can be unwound normally, ensuring normal production of the equipment.

[0064] Optionally, the adhesive member 95 is a special double-sided tape, and one side of the double-sided tape is respectively torn off the first tear-off section 9511 and the second tear-off section 9531 to expose the first adhesive layer 9513 and the second adhesive layer 9533.

[0065] In summary, the tape splicing device 10 of the embodiment of the present invention adopts the following working steps:

[0066] Material preparation stage: The separator 96 is arranged on the side of the main body 951 of the adhesive member 95 away from the first adhesive layer 9513, and is bonded to the second material roll 92 through the third adhesive layer 961. The first tear-off section 9511 and the second tear-off section 9531 of the adhesive member 95 are torn off, and the end 921 of the second material roll 92 is bonded to the first adhesive layer 9513 of the adhesive member 95. The second adhesive layer 9533 forms an adhesive surface 9535 for bonding the working material tape 93. The second material roll 92 is loaded onto the second roll assembly 3.

[0067] Tape splicing stage: The rotating drive end 31 of the second material roll assembly 3 drives the second material roll 92 to rotate, and the identification assembly 6 performs color difference identification on the adhesive surface 9535 of the second material roll 92. After identifying the position of the adhesive surface 9535 of the second material roll 92, the second material roll 92 continues to rotate so that the adhesive surface 9535 of the second material roll 92 is oriented toward the tape pressing part 53 of the tape splicing assembly 5.

[0068] Next, driven by the first drive member 51, the tape pressing member 53 presses one side of the working tape 93 against the adhesive surface 9535 of the second material roll 92. The tape cutting member 55 then cuts and repositions the portion of the working tape 93 connected to the first material roll 91, separating the working tape 93 from the first material roll 91. The second material roll 92 is then rotated until one side of the working tape 93 is completely bonded to the adhesive surface 9535 of the second material roll 92, and the tape pressing member 53 is then repositioned. Finally, the material carrier assembly 841 can receive the unwound material from the second material roll 92, ensuring continuous material feeding of the device.

[0069] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
