Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, and in particular to a one-line roller bonding system. Background Technology

[0002] In the battery manufacturing industry, a continuous supply of material strips is a key factor in ensuring production efficiency and product quality. In this process, the winding and unwinding operations of the material strips are particularly critical, ensuring the continuity and stability of the production process.

[0003] Traditional roll-changing processes typically involve complex mechanical structures and operating procedures. While these methods meet production needs to some extent, they also have many shortcomings.

[0004] Traditional bidirectional roll-over processes often require the entire roll-over shaft to be rotated / flipped. This not only increases the complexity of the mechanical structure but also increases the length of the tail material, leading to waste and ultimately increasing production costs and reducing efficiency. Given these problems, there is an urgent need for an innovative solution to achieve fast and efficient bidirectional roll-over operations. This solution should avoid the entire rotation / flipping of the roll-over shaft, reduce the length of the material strip in the equipment, simplify the equipment structure, reduce equipment costs, and increase roll-over speed. This will improve the efficiency and quality of the battery manufacturing process while reducing resource waste and production costs. Utility Model Content

[0005] In view of this, the purpose of this application is to provide a one-line roller splicing system that enables fast and efficient bidirectional roll changing operations, improves the efficiency and quality of the battery manufacturing process, and reduces resource waste and production costs.

[0006] To achieve the above technical objectives, this application provides a one-line roller splicing system, including a splicing frame, a splicing mechanism, a cutting mechanism, an adhesive application mechanism, and a roll changing and moving device;

[0012] Furthermore, the tape-connecting mechanism includes a tape-connecting drive assembly, a first tape-connecting roller, a second tape-connecting roller, and a roller support;

[0013] The first receiving roller and the second receiving roller are arranged parallel to each other and spaced apart, and are rotatably mounted on the roller bracket;

[0014] The roller support is rotatably mounted on the tape receiving frame, and its rotation center line is parallel to a second direction perpendicular to the first direction;

[0015] The central axis of the first receiving roller and the central axis of the second receiving roller are parallel to the rotation center line of the roller support;

[0016] The belt drive assembly is connected to the roller support and is used to drive the roller support to rotate.

[0017] Furthermore, the cutting mechanism includes a first cutting blade assembly, a second cutting blade assembly, and a cutting blade drive assembly;

[0018] The first cutter assembly and the second cutter assembly are symmetrically arranged with respect to the vertical plane containing the rotation center line of the roller support, and are located below the roller support;

[0019] The cutter drive assembly is connected to the first cutter assembly and the second cutter assembly, and is used to drive the first cutter assembly and the second cutter assembly to move along the Z-axis direction or along the second direction.

[0020] Furthermore, both ends of the first cutter assembly and the second cutter assembly are fixed with sliders;

[0021] The tape receiving frame is provided with a slide rail that is slidably connected to the slider in the Z-axis direction;

[0022] There are two cutter drive components, each connected to the slider, used to drive the slider to move in the Z-axis direction.

[0023] Furthermore, the cutting mechanism also includes a first support roller and a second support roller;

[0024] The first and second support rollers are symmetrically arranged on the vertical plane relative to the rotation center line of the roller bracket, and are rotatably connected to the belt receiving frame.

[0025] The first cutter assembly and the second cutter assembly are capable of moving upward through the space between the first support roller and the second support roller.

[0026] Furthermore, the cutting mechanism includes a first cutting blade assembly, a second cutting blade assembly, and a cutting blade drive assembly;

[0027] The first cutter assembly is rotatably mounted on the roller bracket and is located on one side of the first receiving roller;

[0028] The rotation center line of the first cutter assembly coincides with the central axis of the first receiving roller;

[0029] The second cutter assembly is rotatably mounted on the roller bracket and is located on one side of the second receiving roller;

[0030] The rotation center line of the second cutter assembly coincides with the central axis of the second receiving roller;

[0031] The cutter drive assembly is connected to the first cutter assembly and the second cutter assembly, and is used to drive the first cutter assembly and the second cutter assembly to rotate independently.

[0032] Furthermore, the adhesive applicator includes an adhesive applicator assembly and a first adhesive applicator drive assembly;

[0034] The rotation center line of the adhesive application assembly is parallel to the second direction.

[0035] Furthermore, the adhesive applicator also includes a second adhesive applicator drive assembly;

[0036] The second adhesive application drive component is connected to the adhesive application component and is used to drive the adhesive application component to move along the second direction.

[0037] Furthermore, the first adhesive application drive assembly is disposed on one side of the adhesive application assembly parallel to the second direction, and is connected to the adhesive application assembly via a transmission assembly.

[0038] As can be seen from the above technical solutions, the one-line roller bonding system designed in this application has the following beneficial effects:

[0039] 1. By integrating a tape-jointing mechanism that presses excess material onto a complete roll, a tape-cutting mechanism that cuts excess material, and an adhesive-applying mechanism that applies adhesive to the complete roll, and then driving this mechanism to move in the first direction, the system can move between the first and second tape-changing devices. This eliminates the need for repositioning the tape-changing devices, enabling rapid bidirectional tape changing and significantly accelerating the tape-changing speed. Since repositioning the tape-changing devices is unnecessary, the tape travel length within the system is reduced. Shortening the tape travel length effectively mitigates risks and improves production process stability and product quality.

[0040] 2. The tape splicing mechanism, tape cutting mechanism, and adhesive application mechanism are integrated and installed in parallel within the same tape splicing frame, with their respective drive shafts being parallel or perpendicular to each other. This ensures rapid adhesive application and neat tape splicing, application, and cutting, avoiding tape waste. This structure simplifies the entire system and avoids the space-consuming problem that may result from long tape travel, thus reducing space requirements.

[0041] 3. The simplified system structure, shortened conveyor belt length, and elimination of complex repositioning operations collectively result in cost savings. In manufacturing, the simplified structure reduces the number of parts and manufacturing complexity, lowering production costs. In usage, reduced conveyor belt wear and maintenance costs further reduce long-term operating costs. Attached Figure Description

[0051] This application discloses a one-line roller bonding system.

[0052] Please see Figure 1 as well as Figure 4One embodiment of the one-line roller bonding system provided in this application includes:

[0053] The tape splicing frame 14, tape splicing mechanism 11, tape cutting mechanism 12, adhesive application mechanism 13, and roll changing moving device 2.

[0054] The tape splicing mechanism 11, tape cutting mechanism 12, and adhesive applicator 13 are mounted parallel to each other on the tape splicing frame 14, with their respective drive shafts either parallel or perpendicular to each other. The tape splicing frame 14 further enhances the structural stability of the one-line tape splicing device 1, ensuring the accuracy and reliability of each mechanism during operation. Simultaneously, the design of the tape splicing frame 14 facilitates the installation and maintenance of each mechanism, improving overall operational convenience. The tape splicing frame 14 can be made of high-strength materials (such as steel) to provide excellent load-bearing capacity and resistance to deformation, maintaining structural integrity even under prolonged high-load operation; no specific limitations are imposed.

[0055] The roll changing moving device 2 is connected to the tape receiving frame 14 and is used to drive the tape receiving frame 14 to move.

[0056] The one-line roller bonding system designed in this application is as follows: Figure 4 As shown, it is positioned between the first winding device 3 and the second winding device 4, with the first winding device 3 and the second winding device 4 along a first direction (specifically as shown in the figure). Figure 1 The shown can be considered as the X-axis direction) are arranged in parallel intervals. The first rewinding device 3 includes a first rewinding drive mechanism 31 and a first rewinding shaft 32; the first rewinding drive mechanism 31 is mounted on the rewinding frame 5 (the rewinding frame 5 can be arranged along a second direction perpendicular to the first direction (specifically as shown in the figure)). Figure 1 The first rewinding device (which can be considered as the Y-axis direction) is located on one side of the tape receiving frame 14 and connected to the first rewinding shaft 32 to drive the first rewinding shaft 32 to rotate. The second rewinding device 4 includes a second rewinding drive mechanism 41 and a second rewinding shaft 42; the second rewinding drive mechanism 41 is mounted on the rewinding frame 5 and connected to the second rewinding shaft 42 to drive the second rewinding shaft 42 to rotate. The first rewinding device 3 and the second rewinding device 4 are existing rewinding device structures and will not be described in detail. The rotation center line of the first rewinding shaft 32 and the rotation center line of the second rewinding shaft 42 are parallel to the second direction.

[0057] It should be noted that:

[0058] The adhesive application mechanism 13 is used to apply adhesive at a preset position on the complete roll of material in the first roll changing device 3 (second roll changing device 4). Its drive shaft refers to a drive shaft component or equivalent drive shaft component capable of driving the adhesive application portion in the adhesive application mechanism 13 to move in a certain direction / angle to achieve adhesive application. The following description uses a specific design of the adhesive application mechanism 13 as an example: The adhesive application mechanism 13 includes an adhesive application assembly 131 and a first adhesive application drive assembly 132. The first adhesive application drive assembly 132 is connected to the bottom of the adhesive application assembly 131 and is used to drive the adhesive application assembly 131 to swing. In this case, the drive shaft refers to the drive shaft component that drives the adhesive application assembly 131 to swing using the first adhesive application drive assembly 132. For example, if the first adhesive application drive assembly 132 is a rotary motor, then the drive shaft is its output shaft.

[0059] The tape-joining mechanism 11 is used to press the excess tape from the second rewinding device 4 (first rewinding device 3) onto the adhesive application position of the complete tape roll of the first rewinding device 3 (second rewinding device 4). Its drive shaft refers to a drive shaft or equivalent drive shaft capable of driving the tape-joining portion of the tape-joining mechanism 11 to move in a certain direction / angle to achieve tape joining. The specific design of the tape-joining mechanism 11 in the following text application will be used as an example for illustration: The design of the tape-joining mechanism 11 includes a tape-joining drive assembly 115, a first tape-joining roller 111, a second tape-joining roller 112, and a roller support 114. The tape-joining drive assembly 115 is connected to the roller support 114 and is used to drive the roller support 114 to rotate, thereby driving the first tape-joining roller 111 and the second tape-joining roller 112 to rotate, thus realizing the function of pressing the tape from the excess tape roll onto the tape of the complete tape roll. At this time, the drive shaft refers to the drive shaft component that drives the roller support 114 to rotate via the belt drive assembly 115. For example, if the belt drive assembly 115 is a rotary motor, then the drive shaft is its output shaft.

[0060] The cutting mechanism 12 is used to cut off the excess material roll, thereby completing the roll changing operation. Its drive shaft refers to a drive shaft or equivalent drive shaft capable of driving the cutting portion of the cutting mechanism 12 to move in a certain direction / angle to achieve cutting. The following description uses the specific design of the tape receiving mechanism 11 in this application as an example: For one structural design of the cutting mechanism 12, it includes a first cutter assembly 121, a second cutter assembly 122, and a cutter drive assembly 123. The cutter drive assembly 123 is connected to the first cutter assembly 121 and the second cutter assembly 122, and is used to drive the first cutter assembly 121 and the second cutter assembly 122 to move along the Z-axis direction or along a second direction. One method is to cut directly along the Z-axis by pressure cutting, and the other is to cut along the second direction by sliding cutting. Taking the Z-axis pressure cutting design as an example, the drive shaft here refers to the drive shaft component that drives the first cutter assembly 121 and the second cutter assembly 122 to move along the Z-axis direction. For example, if the cutter drive assembly 123 is a telescopic cylinder, then the drive shaft is the telescopic shaft; if it is a lead screw displacement structure, then its slider can be the equivalent drive shaft, and in this case, the drive shaft is perpendicular to the drive shafts of the other two mechanisms. If the cutting is done in a horizontal sliding cutting manner, then the drive shaft is parallel to the drive shafts of the other two mechanisms.

[0061] By designing their respective drive shafts to be parallel or perpendicular to each other, neatness can be achieved in tape splicing, adhesive application, and tape cutting.

[0062] The one-line roller bonding system designed in this application has the following beneficial effects:

[0063] 1. By integrating the tape-attaching mechanism 11 (which has the function of pressing the excess material roll onto the complete material roll), the tape-cutting mechanism 12 (which has the function of cutting the excess material roll), and the adhesive-applying mechanism 13 (which has the function of applying adhesive to the complete material roll), and driving it to move in the first direction by the roll-changing moving device 2, the system can move between the first roll-changing device 3 and the second roll-changing device 4. This allows the system to quickly achieve bidirectional roll changing without repositioning the roll-changing devices, significantly accelerating the roll-changing speed. Since there is no need to reposition the roll-changing devices, the length of the tape in the system is reduced. Shortening the tape length can effectively reduce these risks and improve the stability of the production process and product quality.

[0064] 2. The tape splicing mechanism 11, tape cutting mechanism 12, and adhesive application mechanism 13 are integrated parallel to each other within the same tape splicing frame 14, and their respective drive shafts are parallel or perpendicular to each other, ensuring rapid adhesive application and achieving neatness in tape splicing, adhesive application, and tape cutting, thus avoiding tape waste. This structure simplifies the entire system structure and avoids the large space occupation problem that may be caused by long tape travel, achieving the goal of reducing space occupation.

[0065] 3. The simplified system structure, shortened conveyor belt length, and elimination of complex repositioning operations collectively result in cost savings. In manufacturing, the simplified structure reduces the number of parts and manufacturing complexity, lowering production costs. In usage, reduced conveyor belt wear and maintenance costs further reduce long-term operating costs.

[0066] The above is Embodiment 1 of the one-line roller bonding tape system provided in this application. The following is Embodiment 2 of the one-line roller bonding tape system provided in this application. Please refer to the following for details. Figures 1 to 4 .

[0067] Based on the solution of Embodiment 1 above:

[0068] Furthermore, taking the first winding device 3 and the second winding device 4 as an example, which are arranged parallel to each other along the first direction:

[0069] The distribution design of the tape splicing mechanism 11, the tape cutting mechanism 12, and the adhesive applicator 13 can be as follows:

[0070] In the Z-axis direction (specifically as follows) Figure 4 The three mechanisms are arranged sequentially from top to bottom along the Z-axis direction (as shown); or, the tape cutting mechanism 12 is installed on the adhesive applicator 13, while the tape receiving mechanism 11 is arranged below the tape receiving mechanism 11 along the Z-axis direction. It can be understood that the three mechanisms have two layout methods: one is arranged sequentially from top to bottom; the other is to integrate the tape receiving mechanism 11 and the tape cutting mechanism 12, and then arrange the tape receiving mechanism 11 (which integrates the tape cutting mechanism 12) and the adhesive applicator 13 vertically.

[0071] Correspondingly, the roll changing moving device 2 moves along the first direction with the drive tape receiving frame 14.

[0072] Furthermore, such as Figure 1 As shown, the tape-joining frame 14 includes two side beams 141 and a bottom beam 142. The two side beams 141 are vertically fixed to both ends of the bottom beam 142, forming a U-shaped frame structure. The roll-changing moving device 2 is fixed to the bottom beam 142 to drive the tape-joining frame 14 to move. The roll-changing moving device 2 can be a linear drive device such as a cylinder or a linear motor, which realizes the movement of the tape-joining frame 14 between the first roll-changing device 3 and the second roll-changing device 4 through linear reciprocating motion.

[0073] Furthermore, such as Figure 1 As shown, the tape receiving mechanism 11 includes a tape receiving drive assembly 115, a first tape receiving roller 111, a second tape receiving roller 112, and a roller support 114.

[0074] The first receiving roller 111 and the second receiving roller 112 are arranged parallel to each other and are rotatably mounted on the roller bracket 114; the roller bracket 114 is rotatably mounted on the receiving frame 14, and its own rotation center line is parallel to the second direction perpendicular to the first direction.

[0075] The roller support 114 may include two roller fixing plates 113. One end of the first receiving roller 111 and the second receiving roller 112 are rotatably connected to one roller fixing plate 113, and the other end is connected to the other roller fixing plate 113. The two roller fixing plates 113 are rotatably connected to the receiving frame 14 through rotating shafts.

[0076] The central axis of the first receiving roller 111 and the central axis of the second receiving roller 112 are parallel to the rotation center line of the roller support 114; ensuring that the first receiving roller 111 and the second receiving roller 112 are set parallel to the first changing device 3 and the second changing device 4, so that the receiving rollers are parallel to the changing rollers of the changing device.

[0077] The tape splicing drive assembly 115 is connected to the roller bracket 114 and is used to drive the roller bracket 114 to rotate. The tape splicing drive assembly 115 can be a motor or other drive device. By driving the roller bracket 114 to rotate, it drives the first tape splicing roller 111 and the second tape splicing roller 112 to rotate, thereby achieving the function of pressing the tape from the tail roll onto the tape of the complete roll. The tape splicing drive assembly 115 can precisely control the rotation angle and speed of the roller bracket 114 to ensure the accuracy and stability of tape splicing.

[0078] The working principle of the tape-connecting mechanism 11 is as follows: Taking the residual material roll of the first changing device 3 first passing through the second tape-connecting shaft as an example, the second tape-connecting shaft can be swung towards the complete material roll of the second changing device 4 by rotating the drive roller bracket 114, so as to press the residual material roll onto the complete material roll. After the residual material roll is cut by the tape-cutting mechanism 12, the complete material roll is switched to first passing through the first tape-connecting roller 111. When the complete material roll is used to become a residual material roll, the first tape-connecting shaft can be swung towards the complete material roll of the first changing device 3 by controlling the rotation of the roller bracket 114, and then pressed. This process is repeated to achieve the pressing of the material rolls between the two changing devices.

[0079] This application uses a rotating roller bracket to switch different splicing rollers to press the excess material roll onto the complete material roll, effectively solving the problem of insufficient clamping force in the traditional swing arm splicing method, which easily leads to deviation during the splicing process. This not only affects the accuracy of splicing but may also have an adverse impact on subsequent processing technology.

[0080] Furthermore, such as Figure 1 as well as Figure 2 As shown, one structural design of the cutting mechanism 12 includes a first cutting blade assembly 121, a second cutting blade assembly 122, and a cutting blade drive assembly 123.

[0081] The first cutting blade assembly 121 and the second cutting blade assembly 122 are symmetrically arranged with respect to the vertical plane where the rotation center line of the roller support 114 lies, and are located below the roller support 114.

[0082] The first cutting blade assembly 121 is disposed near the first winding device 3 and is used to cut off the excess material roll of the first winding device 3; the second cutting blade assembly 122 is disposed near the second winding device 4 and is used to cut off the excess material roll of the second winding device 4.

[0083] The cutter drive assembly 123 is connected to the first cutter assembly 121 and the second cutter assembly 122, and is used to drive the first cutter assembly 121 and the second cutter assembly 122 to move along the Z-axis or along the second direction. It can be understood that there are two cutting methods in this design structure: one is to cut directly in the Z-axis direction by pressure cutting, and the other is to cut along the second direction by sliding cutting.

[0084] Specifically, the Z-axis pressure cutting method involves the cutter drive assembly 123 driving the cutter assembly downwards along the Z-axis until the cutter assembly contacts the material strip, and the material strip is cut by the sharp edge of the cutter assembly itself. This cutting method is suitable for situations where the material strip is relatively thin and the requirements for the cut surface are not high. The second-direction sliding cutting method, on the other hand, involves the cutter drive assembly 123 driving the cutter assembly to move along the second direction, utilizing the shearing force generated by the relative motion between the cutter assembly and the material strip to cut the material strip. This cutting method is suitable for situations where the material strip is relatively thick or where there are certain requirements for the cut surface. In practical applications, the appropriate cutting method can be selected according to specific production needs and material strip characteristics.

[0085] Furthermore, such as Figure 1 as well as Figure 2 As shown, the cutting mechanism 12 also includes a first material support roller 124 and a second material support roller 125.

[0086] The first support roller 124 and the second support roller 125 are symmetrically arranged with respect to the vertical plane of the rotation center line of the roller bracket 114, and are rotatably connected to the tape receiving frame 14; the first cutter assembly 121 and the second cutter assembly 122 can move upward through the space between the first support roller 124 and the second support roller 125; the first support roller 124 is arranged near the first winding device 3; the second support roller 125 is arranged near the second winding device 4.

[0087] The support rollers provide support and guidance for the material strip, ensuring its stability during cutting and preventing deviation or wrinkling, thus improving cutting accuracy and stability. Furthermore, the support rollers are rotatably connected to the tape receiving frame 14, reducing frictional resistance during strip movement.

[0088] Furthermore, such as Figure 1 as well as Figure 2 As shown, taking the movement of the first cutter assembly 121 and the second cutter assembly 122 in the Z-axis direction driven by the cutter drive assembly 123 as an example, the two ends of the first cutter assembly 121 and the second cutter assembly 122 can be fixed to the same slider 127, and then connected to the frame 14 (specifically, the two side beams 141 are fixed with slide rails 126 that are slidably connected to the slider 127). The cooperation between the slider 127 and the slide rail 126 improves the sliding stability of the cutter assembly in the Z-axis direction. For this example, there can be two cutter drive assemblies 123, each a linear cylinder, fixed to the frame 14 and connected to the slider 127, driving the slider 127 to move in the Z-axis direction. Specifically, the piston rod of the linear cylinder is fixedly connected to the slider 127. When the linear cylinder works, the piston rod extends and retracts, driving the slider 127 to move along the slide rail 126 in the Z-axis direction, thereby driving the cutter assembly to move in the Z-axis direction. This drive method has a simple structure, stable power, and is easy to control. Meanwhile, the tight fit between the slider 127 and the slide rail 126 ensures the stability and accuracy of the cutting assembly during movement, thereby improving cutting quality. Furthermore, the stroke of the linear cylinder can be adjusted according to actual needs to adapt to the cutting requirements of different specifications of strip materials.

[0089] The first cutting blade assembly 121 and the second cutting blade assembly 122 may consist of a blade holder and a cutting blade fixed on the blade holder, which will not be described in detail.

[0090] Furthermore, another structural design for the cutting mechanism 12 includes a first cutting blade assembly 121, a second cutting blade assembly 122, and a cutting blade drive assembly 123.

[0091] The first cutting blade assembly 121 is rotatably mounted on the roller bracket 114 and located on one side of the first receiving roller 111; the rotation center line of the first cutting blade assembly 121 coincides with the central axis of the first receiving roller 111.

[0092] The second cutter assembly 122 is rotatably mounted on the roller bracket 114 and located on one side of the second receiving roller 112; the rotation center line of the second cutter assembly 122 coincides with the central axis of the second receiving roller 112.

[0093] The cutter drive assembly 123 is connected to the first cutter assembly 121 and the second cutter assembly 122, and is used to drive the first cutter assembly 121 and the second cutter assembly 122 to rotate independently. There can be two cutter drive assemblies 123, each a rotary cylinder, connected to the first cutter assembly 121 and the second cutter assembly 122 respectively, for driving the first cutter assembly 121 and the second cutter assembly 122 to rotate independently. When the first receiving roller 111 presses the excess material roll onto the complete material roll, the first cutter assembly 121 can be controlled to rotate to cut the excess material roll. Similarly, when the second receiving roller 112 presses the excess material roll onto the complete material roll, the second cutter assembly 122 can be controlled to rotate to cut the excess material roll.

[0094] Regarding the design of the tape receiving frame 14, in order to further improve the structural strength, a reinforcing beam 143 can be added. In order to avoid affecting the operation of the tape receiving mechanism 11, the reinforcing beam 143 can be set below the tape receiving mechanism 11, specifically below the material support roller. Those skilled in the art can make appropriate design changes based on this, without limitation.

[0095] Furthermore, such as Figure 3 As shown, the design of the adhesive applicator 13 includes an adhesive applicator assembly 131 and a first adhesive applicator drive assembly 132.

[0096] The first adhesive application drive assembly 132 is connected to the bottom of the adhesive application assembly 131 and is used to drive the adhesive application assembly 131 to swing. The rotation center line of the adhesive application assembly 131 is parallel to the second direction, so that the first adhesive application assembly 131 can swing closer to the first roll changing device 3 or closer to the second roll changing device 4.

[0097] This design gives the adhesive applicator 13 a high degree of flexibility and adaptability. Under the action of the first adhesive applicator drive assembly 132, the adhesive applicator assembly 131 can precisely swing to the desired position, easily achieving this whether it's near the first roll changer 3 or the second roll changer 4. The rotation center line of the adhesive applicator assembly 131 is parallel to the second direction, ensuring the stability and accuracy of the swing, thereby improving the efficiency and quality of adhesive applicator application. Furthermore, the adhesive applicator 13 has a compact structure, occupies little space, and is easy to integrate and apply on automated production lines.

[0098] Furthermore, the swingable setting of the adhesive application component 131 allows it to swing and rotate from the origin position to contact the surface of the tape roll of one of the tape changers, directly forming a support point with the surface of the tape roll. The bottom of the adhesive application component 131 still uses the origin position as the support point, forming a top contact. This design has the characteristics of triangular stability to ensure that the adhesive application trajectory is not skewed.

[0099] The first adhesive application drive assembly 132 can be a drive device such as a motor, which precisely controls the swing angle and speed of the adhesive application assembly 131 to ensure the accuracy and stability of adhesive application. Alternatively, the first adhesive application drive assembly 132 can be arranged parallel to the second direction on one side of the adhesive application assembly 131 and connected to the adhesive application assembly 131 via a transmission assembly. This design avoids occupying too much space in the second direction, resulting in a more compact structure.

[0100] This application achieves adhesive application to the entire roll by controlling the swing of the adhesive application component 131. Compared with traditional methods that require additional adhesive application components, such as six-axis adhesive application or adhesive application components placed above the roll changing shaft, this effectively reduces the occupation of production space and lowers the configuration cost of the equipment.

[0101] Furthermore, such as Figure 3 As shown, when the width of the material roll's tape is greater than the tape application range of the adhesive application component 131, the tape application cannot be completed in one pass. In this case, the adhesive application mechanism 13 needs to add a second adhesive application drive component 133. The second adhesive application drive component 133 is connected to the adhesive application component 131 and is used to drive the adhesive application component 131 to move along the second direction, so as to achieve tape application at the preset position of the tape in the second direction. Specifically, the first adhesive application drive component 132 and the adhesive application component 131 can be directly mounted on the second adhesive application drive component 133 and driven by the second adhesive application drive component 133.

[0102] This design significantly enhances the flexibility and applicability of the adhesive application mechanism 13. In actual operation, when encountering a wide strip, the first adhesive application drive component 132 can be used to swing the adhesive application component 131 to a suitable application position. Then, the second adhesive application drive component 133 is activated, driving the adhesive application component 131 to move along the second direction, thereby completing the adhesive application across the entire strip width. The addition of the second adhesive application drive component 133 not only improves the adhesive application efficiency but also ensures the application quality, further enhancing the performance of the entire roller-applied splicing system. Simultaneously, this dual-drive component design provides the adhesive application mechanism 13 with more operational possibilities, enabling the system to better adapt to different production needs and strip characteristics.

[0103] The second adhesive application drive assembly 133 can be a linear drive device such as a cylinder. Through precise control, it can be ensured that the adhesive application assembly 131 moves accurately and stably in the second direction, thereby achieving a high-quality adhesive application operation.

[0104] The adhesive application component 131 is designed based on the existing adhesive application mechanism 13, and will not be described in detail.

[0105] The tape splicing process of the one-line roller splicing system designed in this application can be as follows:

[0106] 1. The tape-joining frame 14 is driven by the roll-changing moving device 2 to move closer to the second roll-changing device 4 containing the complete roll of material by a preset distance. Specifically, in response to the roll-changing command, the control device controls the roll-changing moving device 2 to drive the tape-joining frame 14 to move closer to the second roll-changing shaft 42 of the second roll-changing device 4 containing the complete roll of material by a preset distance.

[0107] 2. The adhesive applicator 13 contacts the surface of the complete roll of material and applies adhesive to the surface of the complete roll. Specifically, the control device controls the first adhesive applicator drive assembly 132 of the adhesive applicator 13 to swing the adhesive applicator assembly 131 towards the direction closer to the second roll changer 42 until it contacts the surface of the complete roll of material and applies adhesive to the surface of the complete roll of material. If the width of the material strip of the roll is greater than the adhesive application range of the adhesive applicator assembly 131 in one pass, the second adhesive applicator drive assembly 133 is controlled to move the adhesive applicator assembly 131 in a second direction to achieve adhesive application at a preset position in the second direction.

[0108] 3. The tail roll of the first roll changing device 3 is pressed onto the preset tape-connecting position by the tape-connecting mechanism 11. Specifically, the control device controls the tape-connecting drive assembly 115 to drive the roller bracket 114 to rotate, so that the second tape-connecting roller 112 rotates and presses the tail roll of the first roll changing shaft 32 of the first roll changing device 3 on the second tape-connecting roller 112 onto the preset tape-connecting position.

[0109] 4. The tail roll is cut by the tape cutting mechanism 12. Specifically, the control device controls the cutter drive assembly 123 to drive the first cutter assembly 121 to cut the tail roll, thus completing the tape splicing operation.

[0110] The above provides a detailed description of the one-line roller bonding system provided in this application. For those skilled in the art, based on the ideas of the embodiments of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
